We have filed this Annual  Report on Form 10-K for the year ended  December  31,
2005 (the "Report") without audited financial statements. As audited financial
statements are not contained in the Report, the Report does not satisfy all
requirements under the Securities Exchange Act and, therefore, is deficient.

On March 29, 2006, after discussions with the audit committee and BDO Seidman
LLP, our Independent Registered Public Accounting Firm, and after doing
additional analysis on guidelines set forth in EITF 00-27: Application of Issue
No. 98-5 to Certain Convertible Instruments, our management determined that the
accounting treatment for certain Debentures and Warrants issued between March
2003 and August 2005, was inaccurately reflected in our financial statements
between March 2003 and September 2005 and that these financial statements need
to be restated. The effects of such restatements for the fiscal years ended
December 31, 2004 and 2003 are reflected herein.

We plan on amending the Report as soon as possible to provide audited financial
statements and any other information not included in the Report.

PART I

ITEM 1. Business.

GENERAL

We are a biopharmaceutical company engaged in the clinical development,
manufacture, marketing and distribution of new drug entities based on natural
immune system enhancing technologies for the treatment of viral and immune based
chronic disorders. We were founded in the early 1970s, as a contract researcher
for the National Institutes of Health. Since that time, we have established a
strong foundation of laboratory, pre-clinical, and clinical data with respect to
the development of nucleic acids to enhance the natural antiviral defense system
of the human body and to aid the development of therapeutic products for the
treatment of chronic diseases. We own a U.S. Food and Drug Administration
("FDA") approved GMP (good manufacturing practice) manufacturing facility in New
Jersey.


1
Our flagship  products  include  Ampligen(R)  and Alferon N  Injection(R).
Ampligen(R) is an experimental drug currently undergoing clinical development
for the treatment of: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome
("ME/CFS" or "CFS"), and HIV. In August 2004, we completed a Phase III clinical
trial ("AMP 516") treating over 230 ME/CFS patients with Ampligen(R) and are
presently in the process of preparing a new drug application ("NDA") to be filed
with the FDA. Over its developmental history, Ampligen(R) has received various
designations, including Orphan Drug Product Designation (FDA), Emergency
(compassionate) Cost Recovery Sales Authorization (FDA) and "promising" clinical
outcome recognition based on the evaluation of certain summary clinical reports
(AHRQ, Agency Health Research Quality). In response to our application for Fast
Track Designation, the FDA has requested additional information to support the
potential of Ampligen(R) to treat a serious or life threatening aspect of
ME/CFS. The definition of the "seriousness of a condition", according to
Guidance for Industry documents published in July, 2004 is "a matter of
judgment, but generally based on its impact on such factors as survival,
day-to-day functioning, or the likelihood that the disease, if left untreated,
will progress from a less severe condition to a more serious one". The FDA
requested a "complete and audited report of the Amp 516 study to determine
whether Ampligen(R) has a clinically meaningful benefit on a serious or life
threatening aspect of ME/CFS in order to evaluate whether the Amp 516 study
results do or do not support a "fast track designation". The FDA has also
invited us to include a schedule for completion of all ME/CFS studies as well as
a proposed schedule for our NDA submission. Because we believe our ME/CFS
studies are complete, we intend to request a pre-NDA meeting to obtain advice on
preparing and submitting our NDA, which may eliminate the need for Fast Track
Designation. Meanwhile, we continue with our existing ongoing efforts to prepare
a complete and audited report of our various studies, including the
well-controlled Amp 516 study. We are using our best efforts to complete the
requisite reports including the hiring of additional staff and various expert
medical/regulatory consultants, but can provide no assurance as to whether the
outcome of this large data collection and filing process (approximately 750
patients, treated more than 45,000 times) will be favorable or unfavorable,
specifically with respect to the FDA's perspective. We plan to use an
independent contractor to file the NDA electronically to facilitate the review
by the FDA. Also, we can provide no guidance as to the tentative date at which
the compilation and filing of such data will be complete, as significant factors
are outside our control including, without limitation, the ability and
willingness of the independent clinical investigators to complete the requisite
reports at an acceptable regulatory standard, the ability to collect overseas
generated data, and the ability of Hollister-Stier facilities to interface with
our own New Brunswick staff/facilities to meet the manufacturing regulatory
standards. In addition, Ampligen(R) is undergoing pre-clinical testing for
possible treatment of avian influenza ("bird flu").

Alferon N Injection(R) is the registered trademark for our injectable
formulation of natural alpha interferon, which is approved by the FDA for the
treatment of genital warts. Alferon N Injection(R) is also in pre-clinical
development for treating Multiple Sclerosis and West Nile Virus ("WNV").

With the threat of an avian influenza pandemic rising and health officials
warning that the virus could develop resistance to current flu treatments, the
pursuit of a cost-effective and capable co-administered immunotherapeutic to
existing antivirals and vaccines has become critical. This combination may
permit the use of lower dosages and fewer injections of the antivirals and
vaccines used to combat avian flu, thereby decreasing the cost of both
immunization programs and treatment programs for the full-blown disease.

In antimicrobial (antibacterial) therapy, which is the best-studied
clinical model, synergistic drug combinations may result in curative
conditions/outcomes, often not observed when the single drugs are given alone.
In the case of avian influenza where global drug supplies are presumptively in
very limited supply relative to potential needs, therapeutic synergistic
combinations could not only affect the disease outcome, but also the number of
individuals able to access therapies.


2
We recently  announced that true therapeutic  synergy had been observed in
the interaction between Ampligen(R) and Tamiflu in the inhibition of the avian
influenza virus. The same synergy was observed in the interaction between
Ampligen(R) and Relenza in December 2005. Cell destruction was measured in vitro
using different drug combinations. True therapeutic synergy is defined by
mathematical equations which indicate that the therapeutic effect observed is in
fact greater than the expected arithmetic sum of the two drugs working
independently, and is referred to by pharmacologists as the "Chou/Talalay"
equations developed at Johns Hopkins University.

In a recently reported study from a vaccine group in Japan, the
incorporation of poly I: poly C (dsRNA) into a nasal administration of a killed
influenza A preparation converted a poorly immunogenic response into a highly
efficacious vaccine in protection of mice from lethal infection from human
influenza A. Ampligen(R) is a dsRNA which currently is undergoing testing in
this animal model.

Recently, at the fourth annual Biodefense Research Meeting of the American
Society of Microbiology held in Washington, D.C., we presented results of
laboratory testing that showed our two investigational immunotherapeutics,
Ampligen(R) and Alferon(R), are potentially useful against H5N1, or avian flu,
virus. The pre-clinical research indicates that Ampligen(R), a specifically
configured double-stranded RNA, can provide cross-protection against avian flu
viral mutations as well as boost the effectiveness of Tamiflu and Relenza, the
only two drugs formally recognized for combating bird flu, up to 100 times.
Other lab tests, in healthy human volunteers, indicate that Alferon(R) LDO (Low
Dose Oral), a new delivery form of an anti-viral with prior regulatory approval
for a category of sexually transmitted diseases, can stimulate genes that induce
the production of interferon and other immune compounds, key building blocks in
the body's defense system. The studies were conducted in conjunction with the
National Institute of Infectious Diseases of Japan.

We have recently entered into an agreement with Defence R&D Canada,
Suffield ("DRDC Suffield"), an agency of the Canadian Department of National
Defence, to evaluate the antiviral efficacy of our experimental therapeutic
Ampligen(R) and Alferon(R) for protection against human respiratory influenza
virus infection in well validated animal models. DRDC Suffield is conducting
research and development of new drugs that could potentially become part of the
arsenal of existing antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the respiratory influenza
virus infection on a mouse-adapted strain of human influenza. DRDC Suffield has
already conducted extensive research in the use of liposome delivery technology
to enhance the antiviral activity of a closely-allied Ampligen(R) analogue, Poly
ICLC (an immunomodulating dsRNA) which is very similar to Ampligen(R). Results
suggest that ribonucleic acid-based drugs have the ability to elicit protective
broad-spectrum antiviral immunity against various pathogenic viruses. Hence,
there is the potential for efficacy to be maintained against mutating strains of
an influenza virus. Liposomes, a carrier system for nucleic acid-based drugs,
have shown an ability to protect these drugs against in vivo degradation,
delivering them to intracellular sites of infection, thereby reducing any
toxicity and prolonging their therapeutic effectiveness. Protection can be
afforded for 21 days with two doses of dsRNA. It is believed that in humans with
active flu infection, Tamiflu, given twice daily, may ameliorate symptoms.


3
We have over 100  patents  worldwide  with 9  additional  patents  pending
comprising our intellectual property. We continually review our patents rights
to determine whether they have continuing value. Such review includes an
analysis of the patent's ultimate revenue and profitability potential on an
undiscounted cash basis to support the realizability of our respective
capitalized cost. In addition, management's review addresses whether each patent
continues to fit into our strategic business plans. We have a fully
commercialized product (Alferon N Injection(R)), and a GMP certified
manufacturing facility.

In March 2004, we completed the step-by-step acquisition from Interferon
Sciences, Inc. ("ISI") of ISI's commercial assets, Alferon N Injection(R)
inventory, a worldwide license for the production, manufacture, use, marketing
and sale of Alferon N Injection(R), as well as, a 43,000 square foot
manufacturing facility in New Jersey and the acquisition of all intellectual
property related to Alferon Injection(R). Alferon N Injection(R) is a natural
alpha interferon that has been approved by the FDA for commercial sale for the
intra-lesional treatment of refractory or recurring external genital warts in
patients 18 years of age or older. The acquisition was completed in Spring 2004
with the acquisition of all world wide commercial rights.

We completed the transfer and consolidation of our Rockville Quality
Assurance Lab and equipment into our New Brunswick facility in 2005. We believe
this newly consolidated lab will provide more efficiency with regard to the
quality assurance needs for both Ampligen(R) and Alferon N Injection(R).

On December 9, 2005, we executed a Supply Agreement with Hollister-Stier
Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for the contract
manufacturing of Ampligen(R) for a five year term. Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier will formulate and bottle
the Ampligen(R). In November 2005, we paid $100,000 as a deposit in order to
initiate the manufacturing project. This deposit was expensed as research and
development during the 4th Quarter 2005. The achievement of the initial
objectives described in the agreement, in combination with our polymer
production facility under construction in New Brunswick, N.J., may enable us to
manufacture the raw materials for approximately 10,000 doses of Ampligen(R) per
week. We executed a confidentiality agreement with Hollister-Stier; therefore,
we commenced the transfer of our manufacturing technology to Hollister-Stier.
Currently, Hollister-Stier has completed two pilot manufacturing runs of
Ampligen(R) for stability testing.

On February 8, 2006, we executed a Manufacturing and Safety Agreement with
Hyaluron, Inc. ("Hyaluron") of Burlington, Massachusetts, for the formulation,
packaging and labeling of Alferon N Injection(R). Pursuant to the Agreement, we
will supply raw materials in sufficient quantity and provide any pertinent
information to the project.

We outsource certain components of our research and development,
manufacturing, marketing and distribution while maintaining control over the
entire process through our quality assurance group and our clinical monitoring
group.


4
We are in the process of installing an Ampligen(R) raw material production
line within our New Brunswick facility, which is anticipated to be completed and
in production by May 2006. The production of Ampligen(R) raw materials in our
own facilities has obvious advantages with respect to overall control of the
manufacturing procedure of Ampligen(R)'s raw materials, keeping costs down and
controlling regulatory compliance issues (other parts of our 43,000 sq. ft.
wholly owned FDA approved facility are already in compliance for Alferon N
Injection(R) manufacture). This will also allow us to obtain Ampligen(R) raw
materials on a more consistent manufacturing basis. As of December 31, 2005, we
have capitalized approximately $821,000 towards the construction and
installation of this production line at our New Jersey facility. We expect the
first lot of Ampligen(R) raw material to be produced in the second quarter 2006.
We estimate the total cost of establishing this production line to be
$1,900,000, including modifications to our New Brunswick facility. We have also
identified three manufacturers to expand polymer manufacture, if necessary, and
obtained preliminary proposals from two and have initiated discussions with the
third.

Since the completion of our AMP 516 ME/CFS Phase III clinical trial for
use of Ampligen(R) in the treatment of ME/CFS we have received inquiries from
and, under confidentiality agreements, are having dialogue with other companies
regarding marketing opportunities. No proposals or agreements have resulted from
the dialogue, nor can we be assured that any proposals or agreements will result
from these inquiries.

Our principal executive offices are located at One Penn Center, 1617 JFK
Boulevard, Philadelphia, Pennsylvania 19103, and our telephone number is
215-988-0080.

OUR PRODUCTS

Our primary products consist of our experimental compound, Ampligen(R),
our FDA approved natural interferon product, Alferon N Injection(R) and our
experimental liquid natural interferon LDO.

Ampligen(R)

Nucleic acid compounds represent a potential new class of pharmaceutical
products that are designed to act at the molecular level for treatment of human
diseases. There are two forms of nucleic acids, DNA and RNA. DNA is a group of
naturally occurring molecules found in chromosomes, the cell's genetic
machinery. RNA is a group of naturally occurring informational molecules which
orchestrate a cell's behavior and which regulate the action of groups of cells,
including the cells, which comprise the body's immune system. RNA directs the
production of proteins and regulates certain cell activities including the
activation of an otherwise dormant cellular defense against virus and tumors.
Our double-stranded, specifically configured, RNA drug product, trademarked
Ampligen(R), which is administered intravenously, is (or has been) in human
clinical development for various disease indications, including treatment for
ME/CFS, HIV, renal cell carcinoma and malignant melanoma.


5
Our proprietary  development drug technology including Ampligen(R),  which
utilizes specially configured ribonucleic acid ("RNA") is currently protected by
more than 100 patents worldwide with 9 additional patent applications pending to
provide further proprietary protection in various international markets. Certain
patents apply to the use of Ampligen(R) alone and certain patents apply to the
use of Ampligen(R) in combination with certain other drugs. Some composition of
matter patents pertain to other new medications which have a similar mechanism
of action. During 2005, we reviewed our portfolio of patents and patent
applications. As a result of this review, various patents and patent
applications were not renewed. The non-renewed patents consisted mostly of
international origin or were not conducive to oral application.


The main U.S. ME/CFS treatment patent (#6130206) expires October 10, 2017.
Our main patents covering HIV treatment (#4820696, #5063209, and #5091374)
expire on April 11, 2006, November 5, 2008, and February 25, 2009, respectively;
Hepatitis treatment coverage is conveyed by U.S. patent #5593973 which expires
on January 14, 2014. The U.S. Ampligen(R) Trademark (#1,515,099) expires on
December 6, 2008 and can be renewed thereafter for an additional 10 years. The
FDA has granted us "orphan drug status" for our nucleic acid-derived
therapeutics for ME/CFS, HIV, and renal cell carcinoma and malignant melanoma.
Orphan drug status grants us protection against competition for a period of
seven years following FDA approval, as well as certain federal tax incentives,
and other regulatory benefits. Patent coverage for the HIV indication following
the expiration of patent #4820696, #5063209 and #5091374 is planned to be
obtained from patent pending application #PCT/US 0239890. In the event that this
patent application is not approved, we still have the marketing protection
provided by the orphan drug designation for using Ampligen(R) to treat HIV.

Based on the results of published, peer reviewed pre-clinical studies and
clinical trials, we believe that Ampligen(R) may have broad-spectrum anti-viral
and anti-cancer properties. Approximately 750 patients have participated in
Ampligen(R) clinical trials authorized by the FDA at over twenty clinical trial
sites across the U.S., representing the administration of more than 45,000 doses
of this drug.

We are in the process of preparing an NDA to file with the FDA for the use
of Ampligen(R) in the treatment of patients with ME/CFS.

Alferon N Injection(R)

Interferons are a group of proteins produced and secreted by cells to
combat diseases. Researchers have identified four major classes of human
interferon: alpha, beta, gamma and omega. The Alferon N Injection(R) product
contains a multi-species form of alpha interferon. The worldwide market for
injectable alpha interferon-based products has experienced rapid growth and
various alpha interferon injectable products are approved for many major medical
uses worldwide. Alpha interferons are manufactured commercially in three ways:
by genetic engineering, by cell culture, and from human white blood cells. All
three of these types of alpha interferon are or were approved for commercial
sale in the U.S. Our natural alpha interferon is produced from human white blood
cells.


6
The  potential  advantages of natural alpha  interferon  over  recombinant
(synthetic) interferon produced and marketed by other pharmaceutical firms may
be based upon their respective molecular compositions. Natural alpha interferon
is composed of a family of proteins containing many molecular species of
interferon. In contrast, recombinant alpha interferon each contain only a single
species. Researchers have reported that the various species of interferons may
have differing antiviral activity depending upon the type of virus. Natural
alpha interferon presents a broad complement of species, which we believe may
account for its higher activity in laboratory studies. Natural alpha interferon
is also glycosylated (partially covered with sugar molecules). Such
glycosylation is not present on the currently U.S. marketed recombinant alpha
interferons. We believe that the absence of glycosylation may be, in part,
responsible for the production of interferon-neutralizing antibodies seen in
patients treated with recombinant alpha interferon. Although cell
culture-derived interferon is also composed of multiple glycosylated alpha
interferon species, the types and relative quantity of these species are
different from our natural alpha interferon.

The FDA approved Alferon N Injection(R) in 1989 for the intralesional
(within lesions) treatment of refractory (resistant to other treatment) or
recurring external genital warts in patients 18 years of age or older. Certain
types of human papillomaviruses ("HPV") cause genital warts, a sexually
transmitted disease ("STD"). A published report estimates that approximately
eight million new and recurrent causes of genital warts occur annually in the
United States alone.

The U.S. Alferon(R) Patents expire February 10, 2012 (5,503,828 and
5,676,942) and December 22, 2017 (5,989,441).

Alferon N Injection(R) [Interferon alfa-n3 (human leukocyte derived)] is a
highly purified, natural-source, glycosylated, multi-species alpha interferon
product. There are essentially no antibodies observed against natural interferon
to date and the product has a relatively low side-effect profile. Alferon(R) is
the only natural-source, multi-species alpha interferon currently sold in the
U.S.

The recombinant DNA derived alpha interferon are now reported to have
decreased effectiveness after one year, probably due to antibody formation and
other severe toxicities. These detrimental effects have not been reported with
the use of Alferon N Injection(R) which could allow this product to assume a
much larger market share.

It is our belief that the use of Alferon(R) N in combination with
Ampligen(R) has the potential to increase the positive therapeutic responses in
chronic life threatening viral diseases. Combinational therapy is evolving to
the standard of acceptable medical care based on a detailed examination of the
Biochemistry of the body's natural antiviral response.

Alferon(R) LDO

Alferon(R) LDO is an experimental low-dose, oral liquid formulation of
Natural Alpha Interferon and like Alferon N Injection(R) should not cause
antibody formation, which is a problem with recombinant interferon. It is an
experimental immunotherapeutic believed to work by stimulating an immune cascade
response in the cells of the mouth and throat, enabling it to bolster an immune
response through the entire body orally. Oral interferon would be much more
economically feasible for patients and logistically manageable in development
programs in third-world countries primarily affected by HIV and other emerging
viruses (SARS, Ebola, bird flu, etc.). Oral administration of Alferon(R) N, with
its affordability, low toxicity, no production of antibodies, and broad range of
potential bio activity, could be a breakthrough treatment for viral diseases.


7
A clinical  study to evaluate  the use of  Alferon(R)  LDO in HIV infected
volunteers was initiated during the second quarter 2005 in Philadelphia, PA. The
study is currently being conducted at Drexel University and Philadelphia FIGHT,
a comprehensive AIDS service organization providing primary care, consumer
education, advocacy and research on potential treatments and vaccines. The study
is designed to determine whether Alferon(R) LDO can resuscitate the
broad-spectrum antiviral and immunostimulatory genes. As of December 31, 2005,
seven patients have enrolled and completed dosing. We are currently receiving
data from this study and we are in the process of analyzing the results. The
trial methodology may have implications for treating other emerging viruses such
as avian influenza (bird flu).

Oragens

We acquired a series of patents on Oragens, potentially a set of oral
broad spectrum antivirals and immunological enhancers, through a licensing
agreement with Temple University in Philadelphia, PA. We were granted an
exclusive worldwide license from Temple for the Oragens products. These
compounds have been evaluated in various academic laboratories for application
to chronic viral and immunological disorders.

The 2', 5' oligoadenylate synthetase/RNase L system is an important and
widely distributed pathway for the inhibition of viral replication and tumor
growth. The 2', 5' oligoadenylate synthetase, up activation by double-stranded
RNA, synthesizes 2', 5' oligoadenylates (2-5A) from ATP. These bioactive 2-5As
directly activate RNase L, which degrades viral and cellular RNAs resulting in
the inhibition of protein synthesis.

The bioactive 2-5A molecules can be degraded by various hydrolytic
enzymes, resulting in a short half life. Analogues of these bioactive 2-5As,
termed Oragen RNA compounds, have been produced to increase stability and
maintain or increase biological activity without demonstrable toxicity.

Pursuant to the terms of our agreement with Temple, we are obligated to

assistance required. We currently pay a royalty of $30,000 per year to Temple.


RESEARCH AND DEVELOPMENT ("R&D")

Our focus is on developing drugs for use in treating viral and immune
based chronic disorders and diseases including ME/CFS, HIV, HPV, SARS and West
Nile Virus. Our current R&D projects target treatment therapies for ME/CFS, HIV,
HPV and other viral diseases.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome ("ME/CFS")

Chronic Fatigue Syndrome ("CFS"), also known as Chronic Immune Dysfunction
Syndrome ("CFIDS") and, myalgic encephalomyelitis ("ME") is a serious and
debilitating chronic illness and a major public health problem. Long
misunderstood, under-recognized, and under-diagnosed, ME/CFS is now recognized
by both the government and private sector as a major health problem, including
the National Institutes of Health, U.S. Centers for Disease Control and
Prevention ("CDC"), FDA and Social Security Administration, recognizes CFS as
one of the most common chronic illnesses of our time. The CDC listed ME/CFS as a
priority disease, causing severe health and financial problems for the patients,
their family, and the community. ME/CFS is endemic in the population, but
occasionally seen in clusters suggesting an infectious basis. A variety of
immunological, endocrine, autonomic nervous system, and metabolic abnormalities
have been documented. A groundbreaking, community-based study of ME/CFS by Dr.
Leonard Jason was published in the Archives of Internal Medicine in 1999 and
showed a prevalence rate of 422 of every 100,000 Americans. As many as 800,000
people nationwide suffer from CFS, twice the number previously estimated by the
CDC. Furthermore, 90% of the patients with the illness are struggling without
the benefit of medical diagnosis or treatment. While ME/CFS strikes people of
all age, racial, ethnic, and socioeconomic groups, it is most prevalent amongst
women. Research has shown that ME/CFS is about three times as common in women as
men, a rate similar to that of many autoimmune diseases, such as multiple
sclerosis and lupus. To put this into perspective, ME/CFS is over four times
more common than HIV infection in women, and the rate of ME/CFS in women is
considerably higher than a woman's lifetime risk of getting lung cancer as
published by the CFIDS Association of America.


8
The most common symptom of ME/CFS is  incapacitating  fatigue,  which does
not subside with rest. Many severe ME/CFS patients become completely disabled or
totally bedridden and are afflicted with severe pain and mental confusion even
at rest. This debilitating tiredness is associated with flu-like symptoms such
as chills, fever, headache, sore throat, painful lymph nodes, muscle aches,
weakness and joint pain. Diagnosis of ME/CFS is a time-consuming and difficult
process which is generally arrived at by excluding other illnesses with similar
symptoms and comparing a patient's symptoms with the case definition.
Overlapping symptoms can occur with several diseases, such as fibromyalgia, Gulf
War Illnesses, and multiple chemical sensitivities. Many diseases have similar
symptoms including Lupus and Lyme disease which so closely mimic ME/CFS that
they need to be considered when making a diagnosis to rule them out.

The case definition for ME/CFS criteria calls for certain symptoms to be
present along with fatigue that interferes with physical, mental, social, and
educational activities. Both the fatigue and symptoms must have occurred for (at
least) a six month period. People with ME/CFS may experience many more than the
symptoms named in the case definition, so knowledgeable physicians will take
this fact into consideration when making a diagnosis (after other possible
reasons for symptoms have been ruled out).

The leading model of ME/CFS pathogenesis is thought to be rooted in
abnormalities in the immune system and brain (central nervous system), both of
which affects and alters the function of the other. Because some cases of
chronic fatigue begin with a flu-like infection, several viruses have been
studied as possible causes because all are relatively common in the general
population, including Human Herpesvirus ("HHV") 6 and 7, Retroviruses,
Epstein-Barr Virus, Enteroviruses, as well as, Mycoplasmas, etc. Whilst, the
etiology is likely to be caused by a collection of factors, including viral,
hormonal, stress, and other triggers for the illness in genetically,
environmentally or otherwise susceptible individuals and continues to be a
subject of discussion.

Most ME/CFS patients are treated symptomatically with traditional
treatments geared toward treating symptoms of the disease, such as improving
quality of sleep, reducing pain and treatment of depression. Clinically, a
number of different therapeutic approaches have been pursued, but with no
significant clinical success.


9
In  1998,  we  were  authorized  by  the  FDA  to  initiate  a  Phase  III
multicenter, placebo-controlled, randomized, double blind clinical trial to
treat 230 patients with ME/CFS in the U.S. The objective of this Phase III,
clinical study, denoted as Amp 516, was to evaluate the safety and efficacy of
Ampligen(R) as a treatment for ME/CFS. Over the course of the study, we engaged
the services of 12 clinical investigators at Medical Centers in California, New
Jersey, Florida, North Carolina, Wisconsin, Pennsylvania, Nevada, Illinois, Utah
and Connecticut. These clinical investigators were medical doctors with special
knowledge of ME/CFS who have recruited, prescreened and enrolled ME/CFS patients
for inclusion in the Phase III Amp 516 ME/CFS clinical trial. This clinical
trial enrolled and randomized over 230 ME/CFS patients. We completed drug dosing
in this trial in August 2004. A preliminary review of the data collected during
this trial indicated that Ampligen(R) improved exercise treadmill performance by
19.0% versus 4.2% in the placebo group, or more than twice the minimum
considered medically significant (6.5%), a statistically significant increase
(p=0.025). The major significance is the ability to safely obtain medical
benefits (increased physical performance) which have largely eluded others.
Also, Ampligen(R) significantly improved important secondary endpoints
associated with Quality of Life. There was no significant difference in the
number of serious adverse events, suggesting that the drug was generally well
tolerated. Given that the FDA has already granted Ampligen(R) Treatment Protocol
Status and Orphan Drug Status based on earlier studies, we believe these
medically and statistically significant results, when finalized, will facilitate
FDA review and approval of Ampligen(R) as a therapy to treat ME/CFS.

Human Immunodeficiency Virus ("HIV")

Over fifteen antiviral drugs are currently approved by the FDA for the
treatment of HIV infection. Most target the specific HIV enzymes, reverse
transcriptase ("RT") and protease. The use of various combinations of three or
more of these drugs is often referred to as Highly Active Anti-Retroviral
Therapy ("HAART"). HAART involves the utilization of several antiretrovirals
with different mechanisms of action to decrease viral loads in HIV-infected
patients. The goal of these combination treatments is to reduce the amount of
HIV in the body ("viral load") to as low as possible. Experience has shown that
using combinations of drugs from different classes is a more effective strategy
than using only one or two drugs. HAART has provided dramatic decreases in
morbidity and mortality of HIV infection. Subsequent experience has provided a
more realistic view of HAART and the realization that chronic HIV suppression
using HAART, as currently practiced, would require treatment for life with
resulting significant cumulative toxicities. The various reverse transcriptase
and protease inhibitor drugs that go into HAART have significantly reduced the
morbidity and mortality connected with HIV; however there has been a significant
cost due to drug toxicity. It was estimated that 50% of HIV deaths were from the
toxicity of the drugs in HAART. Some estimates suggest that it would require as
many as 60 years of HAART for elimination of HIV in the infected patient. Thus
the toxicity of HAART drugs and the enormous cost of treatment make this goal
impractical.

We believe that the concept of Strategic Therapeutic Interruption ("STI")
of HAART provides a unique opportunity to minimize the current deficiencies of
HAART while retaining the HIV suppression capacities of HAART. STI is the
cessation of HAART until HIV again becomes detectable (i.e., rebounds) followed
by resumption of HAART with subsequent suppression of HIV. By re-institution of
HAART, HIV may be suppressed before it can inflict damage to the immune system
of the patient. We believe that Ampligen(R) combined with the STI approach may
offer a unique opportunity to retain HAART's superb ability to suppress HIV
while potentially minimizing its deficiencies. All present approved drugs block
certain steps in the life cycles of HIV. None of these drugs address the immune
system, as Ampligen(R) potentially does, although HIV is an immune-based
disease.


10
By using  Ampligen(R) in combination  with STI of HAART, we will undertake
to boost the patients' own immune system's response to help them control their
HIV when they are off of HAART. Our minimum expectation is that Ampligen(R) has
potential to lengthen the HAART-free time interval with a resultant decrease in
HAART-induced toxicities. The ultimate potential, which of course requires full
clinical testing to accept or reject the hypothesis, is that Ampligen(R) may
potentiate STI of HAART to the point that the cell mediated immune system will
be sufficient to eliminate requirement for HAART. Clinical results of using our
technology has been presented at several International AIDS Scientific Forums.

Our Amp 720 HIV study is a treatment using a Strategic Treatment
Interruption ("STI"). The patients' antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as mono-immunotherapy. Patients, who have completed
at least nine months of Ampligen(R) therapy, were able to stay off HAART for a
total STI duration with a mean time of 29.0 weeks whereas the control group,
which was also taken off HAART, but not given Ampligen(R), had earlier HIV
rebound with a mean duration of 18.7 weeks. Thus, on average, Ampligen(R)
therapy spared the patients excessive exposure to HAART, with its inherent
toxicities, for more than 11 weeks.

Forty one HIV patients have participated in this 64 week study. The rate
of enrollment depends on patient availability and on other products being in
clinical trials for the treatment of HIV, causing competition for the same
patient population. At present, more than 18 FDA approved drugs for HIV
treatment may compete for available patients. The length, and subsequently the
expense of these studies, will also be determined by an analysis of the interim
data, which will determine when completion of the ongoing Phase IIb is
appropriate and whether a Phase III trial will be conducted or not. In case a
Phase III study is required; the FDA might require a patient population
exceeding the current one which will influence the cost and time of the trial.
Accordingly, the number of "unknowns" is sufficiently great to be unable to
predict when, or whether, we may obtain revenues from our HIV treatment
indications.

Human Papilloma Virus (HPV)

Human papillomavirus ("HPV") is one of the most common causes of sexually
transmitted infection in the world. Experts estimate that there are more cases
of genital HPV infection than of any other sexually transmitted disease ("STD")
in the United States. Overall, in the United States, an estimated 20 million
people (15% of the population) are currently infected with HPV, 50-75% of which
is with high-risk types, and about 5.5 million people are infected every year.
It has been estimated that a least 50% of sexually active men and women acquire
genital HPV infection at some point in their lives.

Treating genital warts does not cure a HPV infection. The virus remains in
the body in an inactive state after warts are removed. A person treated for
genital warts may still be able to transmit the infection. Common methods for
removing genital warts involve surgically removing them. Cryotherapy is a method
that entails freezing off the wart with liquid nitrogen and is relatively
inexpensive, safe and effective. The downside to this procedure beyond the pain
factor is it must be performed by a trained health care provider. Laser therapy
(using an intense light to destroy the warts) or surgery (cutting off the warts)
has the advantage of getting rid of warts in a single office visit. However,
treatment can be expensive and the operator must be well-trained in these
methods. In addition, surgery will most likely cause scarring over the afflicted
area.


11
There are additionally a number of topical creams and solutions  available
to treat genital warts. Bloodroot paste is made from naturally occurring
substances, but its effects on treating genital warts are not conclusively
supportive. Condylox (also called podophyllin) is a brown liquid that causes a
burning sensation as it dries, but it must be washed off by 4 to 6 hours
otherwise it may be dangerous. Condylox can be quite expensive as well. Condysil
is an additional cream that may be applied. It consists of "all natural"
ingredients and its producers claim it produces no scarring. The current leading
treatment of genital warts is the topical cream Aldara, but in fact there may be
a reoccurrence rate of up to 40% when this drug is used. Treatment for genital
warts may also come in the form of injections. Intron A is a substance that must
be injected 3 times weekly and Alferon(R) N, which is the only natural source,
multi-species alpha interferon currently sold in the US for HPV treatment, is
injected twice weekly.

Hepatitis C Virus ("HCV")

Hepatitis C infection is typically mild in its early stages, and is often
not diagnosed until a late state when it has caused severe liver disease. A
typical cycle of disease from infection to symptomatic liver disease can take 20
years; therefore, the true impact of HCV may not be fully apparent. Hepatitis C
is believed to be transmitted only by blood. However, unlike many other blood
borne viruses (like HCV), virtually any source of blood products seems to be
capable of carrying the virus, even if the source is indirect like a used razor,
for example. This makes Hepatitis C far more transmittable than most other blood
borne viruses including HIV.

Hepatitis C is an RNA virus. Once an infection has begun, Hepatitis C
creates different genetic variations of itself within the body of the host. The
mutated forms are frequently different enough from their ancestor that the
immune system cannot recognize them. Thus, even if the immune system begins to
succeed against one variation, the mutant strains quickly take over and become
new, predominant strains. Thus, the development of antibodies against HCV may
not produce an immunity against the disease like it does with most other
viruses. More than 80% of individuals infected with HCV will progress to a
chronic form of the disease.

The World Health Organization estimates that more than 4.5 million people
in the United States are infected with Hepatitis C and more than 200 million
worldwide. A vaccine against Hepatitis C is not available and there are many
times more people infected with HCV than HIV (the virus that causes AIDS). It is
anticipated that without prompt intervention to treat infected populations, the
death rate from Hepatitis C could surpass that from AIDS.

Alferon N Injection(R) has been studied for the potential treatment of
HIV, Hepatitis C and other indications. ISI, the company from which Hemispherx
obtained rights to Alferon N Injection(R), has conducted clinical trials with
regard to the use of Alferon N Injection(R) in the treatment of HIV and
Hepatitis C. While ISI found the results to be encouraging, in both instances
the FDA determined that additional trials were necessary.


12
We are evaluating  the  possibility of conducting a pivotal trial for HCV.
This trial would be designed to evaluate the efficacy and safety of Alferon N
Injection(R) in comparison with an untreated control group in previously
untreated patients with chronic HCV. The primary endpoint would be the
proportion of patients in whom ALT is normal at the end of 40 weeks of treatment
and at the end of the 24 week follow-up period. We would plan on enrolling
approximately 208 patients. We will be making a decision on this clinical trial
by June 2006.

Other Diseases

A clinical study has been approved by the Clinical Research Ethics
Committee of the Kowloon West Cluster at the Princess Margaret Hospital in Hong
Kong to evaluate the use of Alferon(R) LDO (Low Dose Oral Interferon Alfa-N3,
Human Leukocyte Derived) in normal volunteers and/or asymptomatic subjects with
exposure to a person known to have Severe Acute Respiratory Syndrome ("SARS").
This study completed the dosing of ten patients during the fourth quarter 2005
and we expect to complete analyzing the results of this study in the coming
months.

SARS is one of a group of "emerging" infectious disease that recently
attracted the intense scrutiny of public health officials due to the severity of
disease in epidemics based in Asia, but also involving Europe and North America
as well. An international effort to limit its spread and to identify the
infectious agent has been spectacularly successful and of major significance in
the prevention of a pandemic. A replicating virus of classic coronavirus
morphology was identified initially by electron microscopy. This identification
of the virus family allowed the rapid identification of a new human coronavirus
(SARS-CoV) as the etiological agent of SARS. Recently it has been observed that
the US FDA approved antiviral drug, Alferon(R) (i.e.-natural interferon) has
significant activity against SARS-CoV in vitro as indicated by reduction in
cytopathic effect ("CPE"). This protocol was designed to respond to any
reemergence of SARS with a prophylaxis trial at epidemic sites to be conducted
to evaluate the activity of Alferon(R) LDO (low dose oral) to prevent
symptomatic infection by SARS-CoV. Gene microarray analysis of infection by
SARS-CoV and the effect of Alferon(R) LDO are used in the design and conduct of
this clinical trial. Differential cellular gene responses to infection and the
response to Alferon(R) may predict clinical outcomes.

This trial methodology may have implications for treating other emerging
viruses such as avian influenza. Present production methods for vaccines involve
the use of millions of chicken eggs and would be slow to respond to an outbreak
according to a convened World Health Organization expert panel in November 2004.
Health officials are also concerned that bird flu could mutate to cause the next
pandemic and render present vaccines under development ineffective. We have
prepared more than 300,000 doses of Alferon(R) LDO for appropriate clinical
programs.

With the threat of an avian influenza pandemic rising and health officials
warning that the virus could develop resistance to current flu treatments, the
pursuit of a cost-effective and complementary treatment to existing antivirals
and vaccines has become critical. This combination may permit the use of lower
dosages and fewer injections of the antivirals and vaccines used to combat avian
flu, thereby decreasing the cost of both immunization programs and treatment
programs for the full-blown disease.


13
In  antimicrobial  (antibacterial)  therapy,  which  is  the  best-studied
clinical model, synergistic drug combinations may result in curative
conditions/outcomes, often not observed when the single drugs are given alone.
In the case of avian influenza where global drug supplies are presumptively in
very limited supply relative to potential needs, therapeutic synergistic
combinations could not only affect the disease outcome, but also the number of
individuals able to access therapies.

In a recently reported study from a vaccine group in Japan, the
incorporation of poly I: poly C (dsRNA) into a nasal administration of a killed
influenza A preparation converted a poorly immunogenic response into a highly
efficacious vaccine in protection of mice from lethal infection from human
influenza A. Ampligen(R) is a dsRNA which currently is undergoing testing in the
animal model.

A preclinical study was initiated in June 2005, to determine if
Ampligen(R) enhances the effectiveness of different drug combinations on avian
influenza. The preclinical study suggests a new, and potentially pivotal role of
double-stranded RNA ("dsRNA") therapeutics in improving the efficacy of the
present standards in care in both influenza prevention and treatment of acute
disease. The preclinical study is being conducted by research affiliates of the
National Institutes of Health at Utah State University to examine potential
therapeutic synergies with different drug combinations. The ongoing research is
comparing the relative protection conveyed by Tamiflu (oseltamivir, Roche) and
Relenza (Zanamivir, GlaxoSmithKline) with Ampligen(R) (dsRNA), alone and in
combination, against the avian flu virus (H5N1). Cell destruction was measured
in vitro using different drug combinations. Both drugs, given alone, were
effective in inhibiting cell destruction by avian influenza, but viral
suppression with the combination was greater than either drug alone. The overall
assessment is that there was improvement in cell protection when Ampligen(R) was
combined with oseltamivir carboxylate (Tamiflu) and Zanamivir (Relenza). Further
immediate experimental tests are planned.

Recently, Japanese researchers (Journal of Virology page 2910, 2005) have
found that dsRNAs increase the effectiveness of influenza vaccine by more than
300% and may also convey "cross-protection ability against variant viruses"
(mutated strains of influenza virus). In October 2005, we signed a research
agreement with the National Institute of Infectious Diseases, in Tokyo, Japan.
The collaboration, by Hideki Hasegawa, M.D., Ph.D., Chief of the Laboratory of
Infectious Disease Pathology, will assess our experimental therapeutic
Ampligen(R) as a co-administered immunotherapeutic to the Institution's nasal
flu vaccine.

In October 2005, we also engaged the Sage Group, Inc., a health care,
technology oriented, strategy and transaction advisory firm, to assist us in
obtaining a strategic alliance in Japan for the use of Ampligen(R) in treating
Chronic Fatigue Syndrome or CFS. In the past year leaders in the Japanese
medical community have established the Japanese Society of the Fatigue Science
and the Osaka City University Hospital opened the Fatigue Clinical Center as the
initial step in their Fatigue Research Project.


14
In November  2005,  we entered into an agreement  with Defence R&D Canada,
Suffield ("DRDC Suffield"), an agency of the Canadian Department of National
Defence, to evaluate the antiviral efficacy of our experimental therapeutic
Ampligen(R) and Alferon(R) for protection against human respiratory influenza
virus infection in well validated animal models. DRDC Suffield is conducting
research and development of new drugs that could potentially become part of the
arsenal of existing antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the respiratory influenza
virus infection on a mouse-adapted strain of human influenza. DRDC Suffield has
already conducted extensive research in the use of liposome delivery technology
to enhance the antiviral activity of a closely-allied Ampligen(R) analogue, Poly
ICLC (an immunomodulating dsRNA) which is very similar to Ampligen(R). Results
suggest that ribo nucleic acid-based drugs have the ability to elicit protective
broad-spectrum antiviral immunity against various pathogenic viruses. Hence,
there is the potential for efficacy to be maintained against mutating strains of
an influenza virus. Liposomes, a carrier system for nucleic acid-based drugs,
have shown an ability to protect these drugs against in vivo degradation,
delivering them to intracellular sites of infection, thereby reducing any
toxicity and prolonging their therapeutic effectiveness. Protection can be
afforded for 21 days with two doses of dsRNA. It is believed that in humans with
active flu infection, Tamiflu, given twice daily, may ameliorate symptoms.

A clinical study to evaluate the use of Alferon(R) LDO in HIV infected
volunteers was initiated during the second quarter 2005 in Philadelphia, PA. The
study is currently being conducted at two sites, Drexel University and
Philadelphia FIGHT, a comprehensive AIDS service organization providing primary
care, consumer education, advocacy and research on potential treatments and
vaccines. The study is designed to determine whether Alferon(R) LDO can
resuscitate the broad-spectrum antiviral and immunostimulatory genes. The
initial patient enrolled in this study in July 2005 and, as of December 2005,
seven patients have enrolled and completed dosing. We are currently receiving
data from this study and we are in the process of analyzing the results. The
trial methodology may have implications for treating other emerging viruses such
as avian influenza (bird flu). Present production methods for vaccines involve
the use of millions of chicken eggs and would be slow to respond to an outbreak
according to a recently convened WHO expert panel in November 2004. Health
officials are also concerned that bird flu could mutate to cause the next
pandemic and render present vaccines under development ineffective.

In September 2004, we commenced a clinical trial using Alferon N
Injection(R) to treat patients infected with the West Nile Virus. The infectious
Disease section of New York Queens Hospital and the Weill Medical College of
Cornell University are conducting this double-blinded, placebo controlled trial.
This study plans to enroll 60 patients as they become available. As of December
31, 2005, nine patients have entered this study. The CDC reports that 2,819
cases of West Nile Virus have been reported in the US as of January 10, 2006,
including 105 deaths.

In 2005 we completed the transfer and consolidation of our Rockville
Quality Assurance Lab and equipment into our New Brunswick facility. We believe
this newly consolidated lab will provide more efficiencies with regard to the
quality assurance needs for both Ampligen(R) and Alferon N Injection(R).

An FDA authorized Phase I/II study of Ampligen(R) in cancer, including
patients with renal cell carcinoma was completed in 1994. The results of this
study indicated that patients receiving high doses (200-500mg) twice weekly
experienced an increase in medium survival compared to the low dose group and as
compared to an historical control group. We received authorization from the FDA
to initiate a Phase II study using Ampligen(R) to treat patients with metastatic
renal cell carcinoma. Patients with metastatic melanoma were included in the
Phase I/II study of Ampligen(R) in cancer. The FDA has authorized us to conduct
a Phase II clinical trial using Ampligen(R) in melanoma. We do not expect to
devote any significant resources to funding these studies in the near future.


15
MANUFACTURING

Historically, we have outsourced the manufacturing of Ampligen(R) to
certain contractor facilities in the United States and South Africa while
maintaining full quality control and supervision of the process. Nucleic Acid
polymers constitute the raw material used in the production of Ampligen(R). We
previously acquired our raw materials from Ribotech, Ltd. ("Ribotech") located
in South Africa. Ribotech, is jointly owned by us (24.9%) and Bioclones
(Proprietary), Ltd. (75.1%). Bioclones manages and operates Ribotech. There are
a limited number of manufacturers in the United States available to provide the
polymers. At present, we do not have any agreements with third parties for the
supply of any of such materials. In order to obtain Ampligen(R) raw materials of
higher quality (GMP certified) and on a more regular production basis, we are
setting up polymer manufacturing operations in our New Brunswick facility. This
consolidation and transfer of manufacturing operations has been implemented in
response to a recent inspection of the Ribotech facility in South Africa, our
previous supplier of polymers. This facility is not, at present, suitable for
the commercial manufacture of polymers used to make Ampligen(R). We have also
identified and contacted two manufacturers for the possible manufacture of
polymers. Engagement of either of these facilities would provide back up to our
NJ facility and additional production capacity. This transfer of polymer
manufacturing to our own facilities, and/or to another contract manufacturer may
delay certain steps in commercialization process, specifically, our NDA filing.

Until 1999, we distributed Ampligen(R) in the form of a freeze-dried
powder to be formulated by pharmacists at the site of use. We perfected a
production process to produce ready to use liquid Ampligen(R) in a dosage form,
which will mainly be used upon commercial approval of Ampligen(R). We had
engaged the services of Schering-Plough ("Schering") to mass produce
ready-to-use Ampligen(R) doses; however, in connection with settling various
manufacturing infractions previously noted by the FDA, Schering entered into a
"Consent Decree" with the FDA whereby, among other things, it agreed to
discontinue various contract (third party) manufacturing activities at various
facilities including its San Juan, Puerto Rico, plant. Ampligen(R) (which was
not involved in any of the cited infractions) was produced at this Puerto Rico
plant from year 2000-2004. Operating under instructions from the Consent Decree,
Schering advised us that it would no longer manufacture Ampligen(R) in this
facility beyond 2004 and would assist us in an orderly transfer of said
activities to other non Schering facilities.

On December 9, 2005, we executed a Supply Agreement with Hollister-Stier
Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for the contract
manufacturing of Ampligen(R) for a five year term. Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier will formulate and bottle
the Ampligen(R). In November 2005, we paid $100,000 as a deposit in order to
initiate the manufacturing project. This deposit was expensed as research and
development during the 4th Quarter 2005. The achievement of the initial
objectives described in the agreement, in combination with our polymer
production facility under construction in New Brunswick, N.J., may enable us to
manufacture the raw materials for approximately 10,000 doses of Ampligen(R) per
week. We executed a confidentiality agreement with Hollister-Stier; therefore,
we commenced the transfer of our manufacturing technology to Hollister-Stier.
Currently, Hollister-Stier has completed two pilot manufacturing runs of
Ampligen(R) for stability testing.


16
We have  identified  two other cGMP  production  facilities  in the United
States capable of manufacturing Ampligen(R). Engagement of either of these
facilities would provide back-up to Hollister-Stier and/or provide additional
production capacity if needed. We are reviewing proposals from these production
facilities and expect to act upon one or the other at the appropriate time.

The purified drug concentrate utilized in the formulation of Alferon N
Injection(R) is manufactured in our New Brunswick, New Jersey facility and
Alferon N Injection(R) was formulated and packaged at a production facility
formerly owned and operated by Abbott Laboratories located in Kansas. Abbott
Laboratories has sold the facility to Hospira. Hospira recently completed the
production of 11,590 vials. Hospira is ceasing the labeling and packaging of
Alferon N Injection(R) as they are seeking larger production runs for cost
efficiency purposes. We have identified two manufacturers and, on February 8,
2006, we executed a Manufacturing and Safety Agreement with Hyaluron, Inc.
("Hyaluron") of Burlington, Massachusetts, for the formulation, packaging and
labeling of Alferon N Injection(R). Pursuant to the Agreement, we will supply
raw materials in sufficient quantity and provide any pertinent information to
the project.

We have begun preliminary work to convert the third lot of approximately
13,000 vials to finished goods inventory with an anticipated completion date for
the third quarter 2006. By the first quarter 2007, we anticipate manufacturing
new Alferon N Injection(R) lots from blood leukocytes at our New Jersey
facility. Final formulation and packaging would be completed by a third party
contractor as noted above.

The transfer of Ampligen(R) raw materials production to our own facilities
has obvious advantages with respect to overall control of the manufacturing
procedure of Ampligen(R)'s raw materials, keeping costs down and controlling
regulatory compliance issues (other parts of the of our 43,000 sq. ft. wholly
owned FDA approved facility are already in compliance for Alferon N Injection(R)
manufacture). This will also allow us to obtain Ampligen(R) raw materials on a
more consistent manufacturing basis. As of December 31, 2005, we have
capitalized approximately $821,000 towards the construction and installation of
this production line at our New Jersey facility. The anticipated completion date
for the facility is first quarter 2006 with the first lot of Ampligen(R) raw
material being produced in the second quarter 2006. We estimate the total cost
of establishing this production line to be some $1,900,000, including
modifications to our New Brunswick facility. This polymer production line will
have the capacity to produce up to four kilograms per week, or 100 kilograms per
year which should allow us to manufacture up to one-half million 400 mg doses
per year. We have also identified three contract manufacturers to expand polymer
manufacture, if necessary, and obtained preliminary proposals from two and
initiated discussions with the third.


MARKETING/DISTRIBUTION

Our marketing strategy for Ampligen(R) reflects the differing health care
systems around the world, and the different marketing and distribution systems
that are used to supply pharmaceutical products to those systems. In the U.S.,
we expect that, subject to receipt of regulatory approval, Ampligen(R) will be
utilized in four medical arenas: physicians' offices, clinics, hospitals and the
home treatment setting. We currently plan to use a service provided in the home
infusion (non-hospital) segment of the U.S. market to execute direct marketing
activities, conduct physical distribution of the product and handle billing and
collections. Accordingly, we are developing marketing plans to facilitate the
product distribution and medical support for indication, if and when they are
approved, in each arena. We believe that this approach will facilitate the
generation of revenue without incurring the substantial costs associated with a
sales force. Furthermore, management believes that the approach will enable us
to retain many options for future marketing strategies. In February 1998, we and
Accredo Health Services (formerly Gentiva Health Services) entered into a
Distribution/Specialty Agreement for the distribution of Ampligen(R) for the
treatment of ME/CFS patients under the U.S. treatment protocols.



17
In Europe, we plan to adopt a country-by-country and, in certain cases, an
indication-by-indication marketing strategy due to the heterogeneity regulation
and alternative distribution systems in these areas. We also plan to adopt an
indication-by-indication strategy in Japan. Subject to receipt of regulatory
approval, we plan to seek strategic partnering arrangements with pharmaceutical
companies to facilitate introductions in these areas. The relative prevalence of
people from target indications for Ampligen(R) varies significantly by
geographic region, and we intend to adjust our clinical and marketing planning
to reflect the specialty of each area. In October 1994, we entered into a
licensing agreement with Bioclones (Propriety) Limited ("Bioclones") with
respect to co-development of various RNA drugs, including Ampligen(R), for a
period ending three years from the expiration of the last licensed patents. The
licensing agreement provided SAB/Bioclones with an exclusive manufacturing and
marketing license for certain southern hemisphere countries (including certain
countries in South America, Africa and Australia as well as the United Kingdom
and Ireland (the licensed territory). We deem this marketing arrangement with
Bioclones void due to the numerous and long standing failures of performance by
Bioclones. In Spain, Portugal and Andorra we have entered into a Sales
Distribution Agreement with Laboratorios del Dr. Esteve, S. A., a major
pharmaceutical firm headquartered in Spain.

We continue our efforts to establish an internal marketing and sales
infrastructure to support the sales of Alferon N Injection(R) in the United
States. We continually search for qualified sales managers to increase sales
coverage in all major US markets. Our current sales force includes three
regional sales managers in Texas, Florida and New York. Our sales force will
introduce Alferon N Injection(R) and promote Alferon N Injection(R) to OB GYN's,
dermatologists, and infectious disease physicians and particularly STD Clinics,
who are involved in the treatment of patients with refractory or recurring
external genital warts, as well as physicians about the growing problem and the
risks of HPV. We also intend to expand our marketing/sales programs on an
international basis with our primary focus on Europe. This program is being
designed to engage European pharmaceutical distributors to market and distribute
Alferon N Injection(R).


COMPETITION

Our potential competitors are among the largest pharmaceutical companies
in the world, are well known to the public and the medical community, and have
substantially greater financial resources, product development, and
manufacturing and marketing capabilities than we have.

These companies and their competing products may be more effective and
less costly than our products. In addition, conventional drug therapy, surgery
and other more familiar treatments will offer competition to our products.
Furthermore, our competitors have significantly greater experience than we do in
pre-clinical testing and human clinical trials of pharmaceutical products and in
obtaining FDA, EMEA Health Protection Branch ("HPB") and other regulatory
approvals of products. Accordingly, our competitors may succeed in obtaining
FDA, EMEA and HPB product approvals more rapidly than us. If any of our products
receive regulatory approvals and we commence commercial sales of our products,
we will also be competing with respect to manufacturing efficiency and marketing
capabilities, areas in which we have no experience. Our competitors may possess
or obtain patent protection or other intellectual property rights that prevent,
limit or otherwise adversely affect our ability to develop or exploit our
products.


18
The major  competitors  with drugs to treat HIV  diseases  include  Gilead
Pharmaceutical, Pfizer, Bristol-Myers, Abbott Labs, Glaxo Smithkline, Merck and
Schering-Plough Corp. Alferon N Injection(R) currently competes with a product
produced by Schering for treating genital warts. 3M Pharmaceutical also has
received FDA approval for its immune response modifier product, Aldera, for the
treatment of genital and perianal warts. We believe the approval and marketing
of this product is the main reason that sales of Alferon N Injection(R) have not
met our expectations in the current year.


GOVERNMENT REGULATION

Regulation by governmental authorities in the U.S. and foreign countries
is and will be a significant factor in the manufacture and marketing of Alferon
N products and our ongoing research and product development activities.
Ampligen(R) and the products developed from the ongoing research and product
development activities will require regulatory clearances prior to
commercialization. In particular, new human drug products for humans are subject
to rigorous preclinical and clinical testing as a condition for clearance by the
FDA and by similar authorities in foreign countries. The lengthy process of
seeking these approvals, and the ongoing process of compliance with applicable
statutes and regulations, has required, and will continue to require the
expenditure of substantial resources. Any failure by us or our collaborators or
licensees to obtain, or any delay in obtaining, regulatory approvals could
materially adversely affect the marketing of any products developed by us and
our ability to receive product or royalty revenue. We have received orphan drug
designation for certain therapeutic indications, which might, under certain
conditions, accelerate the process of drug commercialization. Alferon N
Injection(R) is only approved for use in intralesional treatment of refractory
or recurring external genital warts in patients 18 years of age or older. Use of
Alferon N Injection(R) for other applications requires regulatory approval.

A "Fast-Track" designation by the FDA, while not affecting any clinical
development time per se, has the potential effect of reducing the regulatory
review time by fifty percent (50%) from the time that a commercial drug
application is actually submitted for final regulatory review. Regulatory
agencies may apply a "Fast Track" designation to a potential new drug to
accelerate the approval and commercialization process. Criteria for "Fast Track"
include: a) a devastating disease without adequate therapy and b) laboratory or
clinical evidence that the candidate drug may address the unmet medical need. As
of this date, we have not received a Fast-Track designation for any of our
potential therapeutic indications although we have received "Orphan Drug
Designation" for both ME/CFS and HIV/AIDS in the U.S. We will continue to
present data from time to time in support of obtaining accelerated review. We
have not yet submitted any NDA for Ampligen(R) or any other drug to a North
American regulatory authority. In 2000, we submitted an emergency treatment
protocol for clinically-resistant HIV patients, which was withdrawn by us during
the statutory 30 day regulatory review period in favor of a set of individual
physician-generated applications. There are no assurances that authorizations to
commence such treatments will be granted by any regulatory authority or that the
resultant treatments, if any, will support drug efficacy and safety. In 2001, we
did receive FDA authorization for two separate Phase IIb HIV treatment protocols
in which our drug is combined with certain presently available antiretroviral
agents. Interim results were presented in 2002 and 2003 at various international
scientific meetings.


19
We are subject to various federal,  state and local laws,  regulations and
recommendations relating to such matters as safe working conditions, laboratory
and manufacturing practices, the experimental use of animals and the use of and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds and infectious disease agents, used in connection with our research
work. The laboratory and production facility in New Brunswick, New Jersey, which
we acquired from ISI, is approved for the manufacture of Alferon N Injection(R)
and we believe it is in substantial compliance with all material regulations.
However, we cannot give assurances that facilities owned and operated by third
parties that are utilized in the manufacture of our products, are in substantial
compliance, or if presently in substantial compliance, will remain so.


RESEARCH AND DEVELOPMENT/COLLABORATIVE AGREEMENTS

In 1994, we entered into a licensing agreement with Bioclones
(Proprietary) limited ("Bioclones") for manufacturing and international market
development in Africa, Australia, New Zealand, Tasmania, the United Kingdom,
Ireland and certain countries in South Africa, of Ampligen(R) and Oragen(TM). We
deem this marketing arrangement with Bioclones void due to the numerous and long
standing failures of performance by Bioclones. On December 27, 2004 we initiated
a lawsuit in Federal Court identifying a conspiratorial group seeking to
illegally manipulate our stock for purposes of bringing about a hostile takeover
of Hemispherx. This conspiratorial group includes Bioclones.

In 1998, we entered into a strategic alliance with Accredo to develop
certain marketing and distribution capacities for Ampligen(R) in the United
States. Accredo is one of the nation's largest home health care companies with
over 400 offices and sixty thousand caregivers nationwide. Pursuant to the
agreement, Accredo assumed certain responsibilities for distribution of
Ampligen(R) for which they received a fee. Through this arrangement, we may
mitigate the necessity of incurring certain up-front costs. Accredo has also
worked with us in connection with the Amp 511 ME/CFS cost recovery treatment
program, Amp 516 ME/CFS Phase III clinical trial and the Amp 719 (combining
Ampligen(R) with other antiviral drugs in HIV-salvage therapy and Amp 720 HIV
Phase IIb clinical trials now under way). There can be no assurances that this
alliance will develop a significant commercial position in any of its targeted
chronic disease markets. The agreement had an initial one year term from
February 9, 1998 with successive additional one year terms unless either party
notifies the other not less than 180 days prior to the anniversary date of its
intent to terminate the agreement. Also, the agreement may be terminated for
uncured defaults, or bankruptcy, or insolvency of either party and will
automatically terminate upon our receiving an NDA for Ampligen(R) from the FDA,
at which time, a new agreement will need to be negotiated with Accredo or
another major drug distributor.


20
The Company acquired a series of patents on Oragens,  potentially a set of
oral broad spectrum antivirals and immunological enhancers, through a licensing
agreement with Temple University in Philadelphia, PA. The Company was granted an
exclusive worldwide license from Temple for the Oragens products. These
compounds have been evaluated in various academic laboratories for application
to chronic viral and immunological disorders. The 2', 5' oligoadenylate
synthetase/RNase L system is an important and widely distributed pathway for the
inhibition of viral replication and tumor growth. The 2', 5' oligoadenylate
synthetase, up activation by double-stranded RNA, synthesizes 2', 5'
oligoadenylates (2-5A) from ATP. These bioactive 2-5As directly activate RNase
L, which degrades viral and cellular RNAs resulting in the inhibition of protein
synthesis. The bioactive 2-5A molecules can be degraded by various hydrolytic
enzymes, resulting in a short half life. Analogues of these bioactive 2-5As,
termed Oragen RNA compounds, have been produced to increase stability and
maintain or increase biological activity without demonstrable toxicity. Pursuant
to the terms of the Company's agreement with Temple, the Company is obligated to
pay royalties of 2% to 4% of sales depending on the amount of technical
assistance required. The Company currently pays a royalty of $30,000 per year to
Temple. This agreement is to remain in effect until the date that the last
licensed patent expires unless terminated sooner by mutual consent or default
due to royalties not being paid. The last Oragen(TM) patent expires on June 1,
2018. The Company records the payment of the royalty as research and development
cost for the period incurred.

In December, 1999, we entered into an agreement with Biovail Corporation
International ("Biovail"). Biovail is an international full service
pharmaceutical company engaged in the formulation, clinical testing,
registration and manufacture of drug products utilizing advanced drug delivery
systems. Biovail is headquartered in Toronto, Canada. The agreement grants
Biovail the exclusive distributorship of our product in the Canadian territories
subject to certain terms and conditions. In return, Biovail agrees to conduct
certain pre-marketing clinical studies and market development programs,
including without limitation, expansion of the Emergency Drug Release Program in
Canada with respect to our products. In addition, Biovail agrees to work with us
in preparing and filing a New Drug Submission with Canadian Regulatory
Authorities at the appropriate time. Biovail invested $2,250,000 in Hemispherx
equity at prices above the then current market price and agreed to make an
additional investment of $1,750,000 based on receiving approval to market
Ampligen(R) in Canada from the appropriate regulatory authorities in Canada. The
agreement requires Biovail to buy exclusively from us and penetrate certain
market segments at specific rates in order to maintain market exclusivity. The
agreement terminates on December 15, 2009, subject to successive two-year
extensions by the parties and subject to earlier termination by the parties for
uncured defaults under the agreement, bankruptcy or insolvency of either party,
or withdrawal of our product from Canada for a period of more than ninety days
for serious adverse health or safety reasons.


21
In  May  2000,  we  acquired  an  interest  in  Chronix  Biomedical  Corp.
("CHRONIX"). Chronix focuses upon the development of diagnostics for chronic
diseases. We issued 100,000 shares of common stock to Chronix toward a total
equity investment of $700,000. Pursuant to a strategic alliance agreement, we
provided Chronix with $250,000 for research and development in an effort to
develop intellectual property on potential new products for diagnosing and
treating various chronic illnesses such as ME/CFS. These costs were expensed as
incurred. The strategic alliance agreement provides us certain royalty rights
with respect to certain diagnostic technology developed from this research and a
right of first refusal to license certain therapeutic technology developed from
this research. The strategic alliance agreement provides us with a royalty
payment of 10% of all net sales of diagnostic technology developed by Chronix
for diagnosing Chronic Fatigue Syndrome, Gulf War Syndrome and Human Herpes
Virus-6 associated diseases. The royalty continues for the longer of 12 years
from September 15, 2000 or the life of any patent(s) issued with regard to the
diagnostic technology. The strategic alliance agreement also provides us with
the right of first refusal to acquire an exclusive worldwide license for any and
all therapeutic technology developed by Chronix on or before September 14, 2012
for treating Chronic Fatigue Syndrome, Gulf War Syndrome and Human Herpes
Virus-6 associated diseases. During the quarter ended December 31, 2002 and
September 30, 2004 we recorded a noncash charge of $292,000 and $373,000,
respectively, with respect to our investment in Chronix. This impairment reduces
our carrying value to reflect a permanent decline in Chronix's market value
based on its then proposed equity offerings.

In March 2002, our European subsidiary Hemispherx S.A. entered into a
Sales and Distribution agreement with Esteve. Pursuant to the terms of the
Agreement, Esteve was granted the exclusive right to market Ampligen(R) in
Spain, Portugal and Andorra for the treatment of ME/CFS. In addition to other
terms and other projected payments, Esteve agreed to conduct certain clinical
trials using Ampligen(R) in the patient population coinfected with HCV and HIV
viruses. The Agreement runs for the longer of ten years from the date of first
arms-length sale in the Territory, the expiration of the last Hemispherx patent
exploited by Esteve or the period of regulatory data protection for Ampligen(R)
in the applicable territory. Pursuant to the terms of the agreement Esteve is to
conduct clinical trials using Ampligen(R) to treat patients with both HCV and
HIV and is required to purchase certain minimum annual amounts of Ampligen(R)
following regulatory approval. Esteve initiated the HIV/HCV clinical trials in
Spain in late 2004, but did not proceed with the trials due to an inability to
enroll a sufficient number of patients. We are discussing with Esteve their
initiation of another clinical trial utilizing Ampligen(R) in another
indication. The agreement is terminable by either party if Ampligen(R) is
withdrawn from the territory for a specified period due to serious adverse
health or safety reasons; bankruptcy, insolvency or related issues of one of the
parties; or material breach of the agreement. Hemispherx may transform the
agreement into a non-exclusive agreement or terminate the agreement in the event
that Esteve does not meet specified percentages of its annual minimum purchase
requirements under the agreement. Esteve may terminate the agreement in the
event that Hemispherx fails to supply Ampligen(R) to the territory for a
specified period of time or certain clinical trials being conducted by
Hemispherx are not successful. The last patent with respect to this agreement
expires on June 5, 2012.

Recently, Japanese researchers (Journal of Virology page 2910, 2005) have
found that dsRNAs increase the effectiveness of influenza vaccine by more than
300% and may also convey "cross-protection ability against variant viruses"
(mutated strains of influenza virus). In October 2005, we signed a research
agreement with the National Institute of Infectious Diseases, in Tokyo, Japan.
The collaboration, by Hideki Hasegawa, M.D., Ph.D., Chief of the Laboratory of
Infectious Disease Pathology, will assess our experimental therapeutic
Ampligen(R) as a co-administered immunotherapuetic to the Institution's nasal
flu vaccine.

In October 2005, we also engaged the Sage Group, Inc., a health care,
technology oriented, strategy and transaction advisory firm, to assist us in
obtaining a strategic alliance in Japan for the use of Ampligen(R) in treating
Chronic Fatigue Syndrome or CFS. In the past year leaders in the Japanese
medical community have established the Japanese Society of the Fatigue Science
and the Osaka City University Hospital opened the Fatigue Clinical Center as the
initial step in their Fatigue Research Project. We are in discussions with the
Sage Group, Inc. to expand its engagement to assist us in obtaining a strategic
alliance in Japan for the use of Ampligen(R) in treating Avaian Flu.


22
In November  2005,  we entered into an agreement  with Defence R&D Canada,
Suffield ("DRDC Suffield"), an agency of the Canadian Department of National
Defence, to evaluate the antiviral efficacy of our experimental therapeutic
Ampligen(R) and Alferon(R) for protection against human respiratory influenza
virus infection in well validated animal models. DRDC Suffield is conducting
research and development of new drugs that could potentially become part of the
arsenal of existing antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the respiratory influenza
virus infection on a mouse-adapted strain of human influenza.

We have entered into agreements for consulting services, which are
performed at medical research institutions and by medical and clinical research
individuals. Our obligation to fund these agreements can be terminated after the
initial funding period, which generally ranges from one to three years or on an
as-needed monthly basis. During the year ending December 31, 2003, 2004 and 2005
we incurred approximately $395,000, $220,000 and $236,000 respectively, of
consulting service fees under these agreements. These costs are charged to
research and development expense as incurred.

On December 9, 2005, we executed a Supply Agreement with Hollister-Stier
Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for the contract
manufacturing of Ampligen(R) for a five year term. Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier will formulate and bottle
the Ampligen(R). In November 2005, we paid $100,000 as a deposit in order to
initiate the manufacturing project. This deposit was expensed as research and
development during the 4th Quarter 2005. The achievement of the initial
objectives described in the agreement, in combination with our polymer
production facility under construction in New Brunswick, N.J., may enable us to
manufacture the raw materials for approximately 10,000 doses of Ampligen(R) per
week. We executed a confidentiality agreement with Hollister-Stier; therefore,
we commenced the transfer of our manufacturing technology to Hollister-Stier.
Currently, Hollister-Stier has completed two pilot manufacturing runs of
Ampligen(R) for stability testing.

On February 8, 2006, we executed a Manufacturing and Safety Agreement with
Hyaluron, Inc. ("Hyaluron") of Burlington, Massachusetts, for the formulation,
packaging and labeling of Alferon N Injection(R). Pursuant to the Agreement, we
will supply raw materials in sufficient quantity and provide any pertinent
information to the project.

The development of our nucleic acid based products requires the commitment
of substantial resources to conduct the time-consuming research, preclinical
development, and clinical trials that are necessary to bring pharmaceutical
products to market and to establish commercial-scale production and marketing
capabilities. During our last three fiscal years, we have directly spent
approximately $12,136,000 in research and development, of which approximately
$5,144,000 was expended in the year ended December 31, 2005. These direct costs
do not include the overhead and administrative costs necessary to support the
research and development effort.


23
HUMAN RESOURCES

As of March 24, 2006, we had 62 personnel consisting of 43 full time
employees, 19 regulatory/research medical personnel on a part-time basis. Part
time personnel are paid on a per diem or monthly basis. 43 personnel are engaged
in our research, development, clinical, and manufacturing effort. 19 of our
personnel perform regulatory, general administration, data processing, including
bio-statistics, financial and investor relations functions. We have no union
employees and we believe our relationship with our employees is good.

While we have been successful in attracting skilled and experienced
scientific personnel, there can be no assurance that we will be able to attract
or retain the necessary qualified employees and/or consultants in the future.


SCIENTIFIC ADVISORY BOARD

Our Scientific Advisory Board consists of individuals who we believe have
particular scientific and medical expertise in Virology, Cancer, Immunology,
Biochemistry and related fields. These individuals will advise us about current
and long term scientific planning including research and development. The
Scientific Advisory Board will hold periodic meetings as needed by the clinical
studies in progress by us. In addition, individual Scientific Advisory Board
Members sometimes will consult with, and meet informally with our employees. All
members of the Scientific Advisory are employed by others and may have
commitments to and/or consulting agreements with other entities, including our
potential competitors. Members of the Scientific Advisory Board are compensated
at the rate of $1,000 per meeting attended or per day devoted to our affairs.



ITEM 1A. Risk Factors.

The following cautionary statements identify important factors that could
cause our actual result to differ materially from those projected in the
forward-looking statements made in this Form 10-K. Among the key factors that
have a direct bearing on our results of operations are:

No assurance of successful product development

Ampligen(R) and related products. The development of Ampligen(R) and our
other related products is subject to a number of significant risks. Ampligen(R)
may be found to be ineffective or to have adverse side effects, fail to receive
necessary regulatory clearances, be difficult to manufacture on a commercial
scale, be uneconomical to market or be precluded from commercialization by
proprietary right of third parties. Our products are in various stages of
clinical and pre-clinical development and, require further clinical studies and
appropriate regulatory approval processes before any such products can be
marketed. We do not know when, if ever, Ampligen(R) or our other products will
be generally available for commercial sale for any indication. Generally, only a
small percentage of potential therapeutic products are eventually approved by
the FDA for commercial sale.

The clinical development of the experimental therapeutic, Ampligen(R) for
CFS was initiated approximately 16 years ago. To date federal health agencies
have yet to reach a consensus regarding various aspects of ME/CFS, including
parameters of "promising therapies" for ME/CFS and which aspects of ME/CFS are
anticipated to be "serious or life-threatening".


24
Over  its   developmental   history,   Ampligen(R)  has  received  various
designations, including Orphan Drug Product Certification (FDA), Emergency
(compassionate) Cost Recovery Sales Authorization (FDA) and "promising" clinical
outcome recognition based on the evaluation of certain summary clinical reports
(AHRQ, Agency Health Research Quality). However to date, the FDA has determined
it has yet to receive sufficient information to support the potential of
Ampligen(R) to treat a serious or life threatening aspect of ME/CFS. The
definition of the "seriousness of a condition", according to Guidance for
Industry documents published in July 2004 is "a matter of judgment, but
generally based on its impact on such factors as survival, day-to-day
functioning, or the likelihood that the disease, if left untreated, will
progress from a less severe condition to a more serious one". The FDA has
recently requested a "complete and audited report of the Amp 516 study to
determine whether Ampligen(R) has a clinically meaningful benefit on a serious
or life threatening aspect of ME/CFS in order to evaluate whether the Amp 516
study results do or do not support a "fast track designation". The FDA has also
invited us to include a schedule for completion of all ME/CFS studies as well as
a proposed schedule for our NDA submission. Because we believe our ME/CFS
studies are complete, we intend to request a pre-NDA meeting to obtain advice on
preparing and submitting our NDA, which may eliminate the need for Fast Track
Designation. Meanwhile, we will continue with our existing ongoing efforts to
prepare a complete and audited report of our various studies, including the
well-controlled Amp 516 study. We are using our best efforts to complete the
requisite reports including the hiring of new staff and various recognized
expert medical/regulatory consultants, but can provide no assurance as to
whether the outcome of this large data collection and filing process
(approximately 750 patients, treated more than 45,000 times) will be favorable
or unfavorable, specifically with respect to the FDA's perspective. Also, we can
provide no guidance as to the tentative date at which the compilation and filing
of such data will be complete, as significant factors are outside our control
including, without limitation, the ability and willingness of the independent
clinical investigators to complete the requisite reports at an acceptable
regulatory standard, the ability to collect overseas generated data, and the
ability of Hollister-Stier facilities to interface with our own New Brunswick
staff/facilities to meet the manufacturing regulatory standards.

Alferon N Injection(R). Although Alferon N Injection(R) is approved for
marketing in the United States for the intralesional treatment of refractory or
recurring external genital warts in patients 18 years of age or older; to date
it has not been approved for other indications. We face many of the risks
discussed above, with regard to developing this product for use to treat other
ailments such as multiple sclerosis and cancer.

Our drug and related technologies are investigational and subject to regulatory
approval. If we are unable to obtain regulatory approval, our operations will be
significantly affected.

All of our drugs and associated technologies, other than Alferon N
Injection(R), are investigational and must receive prior regulatory approval by
appropriate regulatory authorities for general use and are currently legally
available only through clinical trials with specified disorders. At present,
Alferon N Injection(R) is only approved for the intralesional treatment of
refractory or recurring external genital warts in patients 18 years of age or
older. Use of Alferon N Injection(R) for other indications will require
regulatory approval. In this regard, ISI, the company from which we obtained our
rights to Alferon N Injection(R), conducted clinical trials related to use of
Alferon N Injection(R) for treatment of HIV and Hepatitis C. In both instances,
the FDA determined that additional studies were necessary in order to fully
evaluate the efficacy of Alferon N Injection(R) in the treatment of HIV and
Hepatitis C diseases. We have no immediate plans to conduct these additional
studies at this time.


25
Our products,  including Ampligen(R),  are subject to extensive regulation
by numerous governmental authorities in the U.S. and other countries, including,
but not limited to, the FDA in the U.S., the Health Protection Branch ("HPB") of
Canada, and the Agency for the Evaluation of Medicinal Products ("EMEA") in
Europe. Obtaining regulatory approvals is a rigorous and lengthy process and
requires the expenditure of substantial resources. In order to obtain final
regulatory approval of a new drug, we must demonstrate to the satisfaction of
the regulatory agency that the product is safe and effective for its intended
uses and that we are capable of manufacturing the product to the applicable
regulatory standards. We require regulatory approval in order to market
Ampligen(R) or any other proposed product and receive product revenues or
royalties. We cannot assure you that Ampligen(R) will ultimately be demonstrated
to be safe or efficacious. In addition, while Ampligen(R) is authorized for use
in clinical trials in the United States, we cannot assure you that additional
clinical trial approvals will be authorized in the United States or in other
countries, in a timely fashion or at all, or that we will complete these
clinical trials. If Ampligen(R) or one of our other products does not receive
regulatory approval in the U.S. or elsewhere, our operations most likely will be
materially adversely affected.



Although preliminary in vitro testing indicates that Ampligen(R) enhances the
effectiveness of different drug combinations on avian influenza, preliminary
testing in the laboratory is not necessarily predictive of successful results in
clinical testing or human treatment.

Ampligen(R) is undergoing pre-clinical testing for possible treatment of
avian flu. Although preliminary in vitro testing indicates that Ampligen(R)
enhances the effectiveness of different drug combinations on avian flu,
preliminary testing in the laboratory is not necessarily predictive of
successful results in clinical testing or human treatment. No assurance can be
given that similar results will be observed in clinical trials. Use of
Ampligen(R) in the treatment of avian flu requires prior regulatory approval.
Only the FDA can determine whether a drug is safe, effective or promising for
treating a specific application. As discussed in the prior risk factor,
obtaining regulatory approvals is a rigorous and lengthy process.

In addition, Ampligen(R) is being tested on one strain of avian flu. There
are a number of strains and strains mutate. No assurance can be given that a
Ampligen(R) will be effective on any strains that might infect humans.

We may continue to incur substantial losses and our future profitability is
uncertain.

We began operations in 1966 and last reported net profit from 1985 through
1987. Since 1987, we have incurred substantial operating losses, as we pursued
our clinical trial effort and expanded our efforts in Europe. As of December 31,
2005 our accumulated deficit was approximately $149,677,000. We have not yet
generated significant revenues from our products and may incur substantial and
increased losses in the future. We cannot assure that we will ever achieve
significant revenues from product sales or become profitable. We require, and
will continue to require, the commitment of substantial resources to develop our
products. We cannot assure that our product development efforts will be
successfully completed or that required regulatory approvals will be obtained or
that any products will be manufactured and marketed successfully, or be
profitable.


26
We may require additional financing which may not be available.

The development of our products will require the commitment of substantial
resources to conduct the time-consuming research, preclinical development, and
clinical trials that are necessary to bring pharmaceutical products to market.
As of December 31, 2005, we had approximately $16,204,000 in cash and cash
equivalents and short-term investments. These funds should be sufficient to meet
our operating cash requirements, including debt service, for the near term.
However, we may need to raise additional funds through additional equity or debt
financing or from other sources in order to complete the necessary clinical
trials and the regulatory approval processes including the commercializing of
Ampligen(R) products. There can be no assurances that we will raise adequate
funds which may have a material adverse effect on our ability to develop our
products. Also, we have the ability to curtail discretionary spending, including
some research and development activities, if required to conserve cash.

Under the common stock purchase agreement signed with Fusion Capital on
July 8, 2005, we only have the right to receive $40,000 per trading day unless
our stock price equals or exceeds $2.00, in which case the daily amount may be
increased under certain conditions as the price of our common stock increases
(For a more detailed description of the terms of this agreement, see the
agreement filed as an exhibit to our Current Report on Form 8-K filed with the
SEC on July 11, 2005). Fusion Capital does not have the right nor the obligation
to purchase any shares of our common stock on any trading days that the market
price of our common stock is less than $1.00. Since we initially registered
10,000,000 shares purchasable by Fusion Capital pursuant to the common stock
purchase agreement, the selling price of our common stock to Fusion Capital will
have to average at least $2.00 per share for us to receive the maximum proceeds
of $20.0 million without registering additional shares of common stock. As of
March 24, 2006, we need an average selling price of $0.99 per share for the
remainder of the agreement to realize the $20,000,000 in proceeds. The closing
price of our stock was $3.78 on March 24, 2006. Subject to approval by our board
of directors, we have the right, but not the obligation, to issue more than
10,000,000 shares to Fusion Capital. In the event we elect to issue more than
10,000,000 shares, we will be required to file a new registration statement and
have it declared effective by the Securities and Exchange Commission. In the
event that we decide to issue more than 10,113,278 (19.99% of our outstanding
shares of common stock as of the date of our agreement), we would first be
required to seek stockholder approval in order to be in compliance with the
American Stock Exchange Market rules. As of March 24, 2006, Fusion Capital has
purchased 8,211,508 shares amounting to $18,230,011 in our receipt of gross
proceeds.

The extent to which we rely on Fusion Capital as a source of funding will
depend on a number of factors including, the prevailing market price of our
common stock and the extent to which we are able to secure working capital from
other sources. Specifically, Fusion Capital shall not have the right nor the
obligation to purchase any shares of our common stock on any trading days that
the market price of our common stock is less than $1.00. If obtaining sufficient
financing from Fusion Capital were to prove unavailable or prohibitively
dilutive and if we are unable to commercialize and sell Ampligen(R) and/or
increase sales of Alferon N Injection(R) or our other products, we will need to
secure another source of funding in order to satisfy our working capital needs.
Even if we are able to access the full $20.0 million under the common stock
purchase agreement with Fusion Capital, we may still need additional capital to
fully implement our business, operating and development plans. Should the
financing we require to sustain our working capital needs be unavailable or
prohibitively expensive when we require it, the consequences would materially
adversely affect our business, operating results, financial condition and
prospects.

27
We may not be  profitable  unless we can  protect  our  patents  and/or  receive
approval for additional pending patents.

We need to preserve and acquire enforceable patents covering the use of
Ampligen(R) for a particular disease in order to obtain exclusive rights for the
commercial sale of Ampligen(R) for such disease. We obtained all rights to
Alferon N Injection(R), and we plan to preserve and acquire enforceable patents
covering its use for existing and potentially new diseases. Our success depends,
in large part, on our ability to preserve and obtain patent protection for our
products and to obtain and preserve our trade secrets and expertise. Certain of
our know-how and technology is not patentable, particularly the procedures for
the manufacture of our drug product which are carried out according to standard
operating procedure manuals. We have been issued certain patents including those
on the use of Ampligen(R) and Ampligen(R) in combination with certain other
drugs for the treatment of HIV. We also have been issued patents on the use of
Ampligen(R) in combination with certain other drugs for the treatment of chronic
Hepatitis B virus, chronic Hepatitis C virus, and a patent which affords
protection on the use of Ampligen(R) in patients with Chronic Fatigue Syndrome.
We have not yet been issued any patents in the United States for the use of
Ampligen(R) as a sole treatment for any of the cancers, which we have sought to
target. With regard to Alferon N Injection(R), we have acquired from ISI its
patents for natural alpha interferon produced from human peripheral blood
leukocytes and its production process. We cannot assure that our competitors
will not seek and obtain patents regarding the use of similar products in
combination with various other agents, for a particular target indication prior
to our doing such. If we cannot protect our patents covering the use of our
products for a particular disease, or obtain additional patents, we may not be
able to successfully market our products.

The patent position of biotechnology and pharmaceutical firms is highly
uncertain and involves complex legal and factual questions.

To date, no consistent policy has emerged regarding the breadth of
protection afforded by pharmaceutical and biotechnology patents. There can be no
assurance that new patent applications relating to our products or technology
will result in patents being issued or that, if issued, such patents will afford
meaningful protection against competitors with similar technology. It is
generally anticipated that there may be significant litigation in the industry
regarding patent and intellectual property rights. Such litigation could require
substantial resources from us and we may not have the financial resources
necessary to enforce the patent rights that we hold. No assurance can be made
that our patents will provide competitive advantages for our products or will
not be successfully challenged by competitors. No assurance can be given that
patents do not exist or could not be filed which would have a materially adverse
effect on our ability to develop or market our products or to obtain or maintain
any competitive position that we may achieve with respect to our products. Our
patents also may not prevent others from developing competitive products using
related technology.


28
There can be no assurance that we will be able to obtain  necessary  licenses if
we cannot enforce patent rights we may hold. In addition, the failure of third
parties from whom we currently license certain proprietary information or from
whom we may be required to obtain such licenses in the future, to adequately
enforce their rights to such proprietary information, could adversely affect the
value of such licenses to us.

If we cannot enforce the patent rights we currently hold we may be
required to obtain licenses from others to develop, manufacture or market our
products. There can be no assurance that we would be able to obtain any such
licenses on commercially reasonable terms, if at all. We currently license
certain proprietary information from third parties, some of which may have been
developed with government grants under circumstances where the government
maintained certain rights with respect to the proprietary information developed.
No assurances can be given that such third parties will adequately enforce any
rights they may have or that the rights, if any, retained by the government will
not adversely affect the value of our license.

There is no guarantee that our trade secrets will not be disclosed or known by
our competitors.

To protect our rights, we require certain employees and consultants to
enter into confidentiality agreements with us. There can be no assurance that
these agreements will not be breached, that we would have adequate and
enforceable remedies for any breach, or that any trade secrets of ours will not
otherwise become known or be independently developed by competitors.

If our distributors do not market our products successfully, we may not generate
significant revenues or become profitable.

We have limited marketing and sales capability. We are dependent upon
existing and, possibly future, marketing agreements and third party distribution
agreements for our products in order to generate significant revenues and become
profitable. As a result, any revenues received by us will be dependent on the
efforts of third parties, and there is no assurance that these efforts will be
successful. Our agreement with Accredo offers the potential to provide some
marketing and distribution capacity in the United States while agreements with
Biovail Corporation and Laboratorios Del Dr. Esteve S.A. may provide a sales
force in Canada, Spain and Portugal. We also had an agreement with Bioclones
(Proprietary), Ltd ("Bioclones") that covered South America, Africa, United
Kingdom, Australia and New Zealand. However, we deem this marketing arrangement
with Bioclones void due to the numerous and long standing failures of
performance by Bioclones. In addition, in December 2004, we initiated a lawsuit
in Federal Court identifying a conspiratorial group seeking to illegally
manipulate our stock for purposes of bringing about the hostile takeover of
Hemispherx. This conspiratorial group includes Bioclones.

We cannot assure that our domestic or foreign marketing partners will be
able to successfully distribute our products, or that we will be able to
establish future marketing or third party distribution agreements on terms
acceptable to us, or that the cost of establishing these arrangements will not
exceed any product revenues. The failure to continue these arrangements or to
achieve other such arrangements on satisfactory terms could have a materially
adverse effect on us.


29
There are no long-term  agreements with suppliers of required  materials.  If we
are unable to obtain the required raw materials, we may be required to scale
back our operations or stop manufacturing Alferon N Injection(R) and/or
Ampligen(R).

A number of essential materials are used in the production of Alferon N
Injection(R), including human white blood cells. We do not have long-term
agreements for the supply of any of such materials. There can be no assurance we
can enter into long-term supply agreements covering essential materials on
commercially reasonable terms, if at all.

There are a limited number of manufacturers in the United States available
to provide the polymers for use in manufacturing Ampligen(R). At present, we do
not have any agreements with third parties for the supply of any of these
polymers. We are establishing relevant manufacturing operations within our New
Brunswick, New Jersey facility for the production of Ampligen(R) raw materials
in order to obtain polymers on a more consistent manufacturing basis. The
establishment of an Ampligen(R) raw materials production line within our own
facilities, while having obvious advantages with respect to regulatory
compliance (other parts of the of our 43,000 sq. ft. wholly owned FDA approved
facility are already in compliance for the manufacture of Alferon N
Injection(R)), may delay certain steps in the commercialization process,
specifically a targeted NDA filing.

If we are unable to obtain or manufacture the required raw materials, we
may be required to scale back our operations or stop manufacturing. The costs
and availability of products and materials we need for the production of
Ampligen(R) and the commercial production of Alferon N Injection(R) and other
products which we may commercially produce are subject to fluctuation depending
on a variety of factors beyond our control, including competitive factors,
changes in technology, and FDA and other governmental regulations and there can
be no assurance that we will be able to obtain such products and materials on
terms acceptable to us or at all.

There is no assurance that successful manufacture of a drug on a limited scale
basis for investigational use will lead to a successful transition to
commercial, large-scale production.

Small changes in methods of manufacturing, including commercial scale-up,
may affect the chemical structure of Ampligen(R) and other RNA drugs, as well as
their safety and efficacy, and can, among other things, require new clinical
studies and affect orphan drug status, particularly, market exclusivity rights,
if any, under the Orphan Drug Act. The transition from limited production of
pre-clinical and clinical research quantities to production of commercial
quantities of our products will involve distinct management and technical
challenges and will require additional management and technical personnel and
capital to the extent such manufacturing is not handled by third parties. There
can be no assurance that our manufacturing will be successful or that any given
product will be determined to be safe and effective, capable of being
manufactured economically in commercial quantities or successfully marketed.


30
We have limited manufacturing experience and capacity.

Ampligen(R) has been only produced in limited quantities for use in our
clinical trials and we are dependent upon third party suppliers for key
components of our products and for substantially all of the production process.
The failure to continue these arrangements or to achieve other such arrangements
on satisfactory terms could have a material adverse affect on us. Also, to be
successful, our products must be manufactured in commercial quantities in
compliance with regulatory requirements and at acceptable costs. To the extent
we are involved in the production process, our current facilities are not
adequate for the production of our proposed products for large-scale
commercialization, and we currently do not have adequate personnel to conduct
commercial-scale manufacturing. We intend to utilize third-party facilities if
and when the need arises or, if we are unable to do so, to build or acquire
commercial-scale manufacturing facilities. We will need to comply with
regulatory requirements for such facilities, including those of the FDA
pertaining to current Good Manufacturing Practices ("cGMP") regulations. There
can be no assurance that such facilities can be used, built, or acquired on
commercially acceptable terms, or that such facilities, if used, built, or
acquired, will be adequate for our long-term needs.

In connection with settling various manufacturing infractions previously
noted by the FDA, Schering-Plough ("Schering") entered into a "Consent Decree"
with the FDA whereby, among other things, it agreed to discontinue various
contract (third party) manufacturing activities at various facilities including
its San Juan, Puerto Rico, plant. Ampligen(R) (which was not involved in any of
the cited infractions) was produced at this Puerto Rico plant from year
2000-2004. Operating under instructions from the Consent Decree, Schering has
advised us that it would no longer manufacture Ampligen(R) in this facility
beyond 2004 and would assist us in an orderly transfer of said activities to
other non Schering facilities.

On December 9, 2005, we executed a Supply Agreement with Hollister-Stier
Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for the contract
manufacturing of Ampligen(R) for a five year term. Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier will formulate and bottle
the Ampligen(R). We paid a $100,000 deposit in order to initiate the
manufacturing project and expensed this payment as a research and development
cost. The achievement of the initial objectives described in the agreement, in
combination with our polymer production facility under construction in New
Brunswick, N.J., may enable us to manufacture the raw materials for
approximately 10,000 doses of Ampligen(R) per week. We executed a
confidentiality agreement with Hollister-Stier; therefore, we commenced the
transfer of our manufacturing technology to Hollister-Stier. Currently,
Hollister-Stier has completed two pilot manufacturing runs of Ampligen(R) for
stability testing.

We have identified two other capable cGMP facilities in the US for the
manufacture of Ampligen(R) and obtained proposals from both. If either of these
two facilities are acceptable, we would be able to maintain a minimum of two
independent production sites for the production of Ampligen(R). We are in the
process of reviewing these other proposals.

The purified drug concentrate utilized in the formulation of Alferon N
Injection(R) is manufactured in our New Brunswick, New Jersey facility and
Alferon N Injection(R) was formulated and packaged at a production facility
formerly owned and operated by Abbott Laboratories located in Kansas. Abbott
Laboratories has sold the facility to Hospira. Hospira completed the production
of 12,000 vials in November 2005. Hospira ceased the labeling and packaging of
Alferon N Injection(R) as they are seeking larger production runs for cost
efficiency purposes. We have identified two manufacturers to replace Hospira
and, on February 8, 2006, we executed a Manufacturing and Safety Agreement with
Hyaluron, Inc. ("Hyaluron") of Burlington, Massachusetts, for the formulation,
packaging and labeling of Alferon N Injection(R). Pursuant to the Agreement, we
will supply raw materials in sufficient quantity and provide any pertinent
information to the project.


31
We may not be profitable unless we can produce  Ampligen(R) or other products in
commercial quantities at costs acceptable to us.

We have never produced Ampligen(R) or any other products in large
commercial quantities. We must manufacture our products in compliance with
regulatory requirements in large commercial quantities and at acceptable costs
in order for us to be profitable. We intend to utilize third-party manufacturers
and/or facilities if and when the need arises or, if we are unable to do so, to
build or acquire commercial-scale manufacturing facilities. If we cannot
manufacture commercial quantities of Ampligen(R) or enter into third party
agreements for its manufacture at costs acceptable to us, our operations will be
significantly affected. Also, each production lot of Alferon N Injection(R) is
subject to FDA review and approval prior to releasing the lots to be sold. This
review and approval process could take considerable time, which would delay our
having product in inventory to sell.

Rapid technological change may render our products obsolete or non-competitive.

The pharmaceutical and biotechnology industries are subject to rapid and
substantial technological change. Technological competition from pharmaceutical
and biotechnology companies, universities, governmental entities and others
diversifying into the field is intense and is expected to increase. Most of
these entities have significantly greater research and development capabilities
than us, as well as substantial marketing, financial and managerial resources,
and represent significant competition for us. There can be no assurance that
developments by others will not render our products or technologies obsolete or
noncompetitive or that we will be able to keep pace with technological
developments.

Our products may be subject to substantial competition.

Ampligen(R). Competitors may be developing technologies that are, or in
the future may be, the basis for competitive products. Some of these potential
products may have an entirely different approach or means of accomplishing
similar therapeutic effects to products being developed by us. These competing
products may be more effective and less costly than our products. In addition,
conventional drug therapy, surgery and other more familiar treatments may offer
competition to our products. Furthermore, many of our competitors have
significantly greater experience than us in pre-clinical testing and human
clinical trials of pharmaceutical products and in obtaining FDA, HPB and other
regulatory approvals of products. Accordingly, our competitors may succeed in
obtaining FDA, HPB or other regulatory product approvals more rapidly than us.
There are no drugs approved for commercial sale with respect to treating ME/CFS
in the United States. The dominant competitors with drugs to treat HIV diseases
include Gilead Pharmaceutical, Pfizer, Bristol-Myers, Abbott Labs, Glaxo
SmithKline, Merck and Schering-Plough Corp. These potential competitors are
among the largest pharmaceutical companies in the world, are well known to the
public and the medical community, and have substantially greater financial
resources, product development, and manufacturing and marketing capabilities
than we have. Although we believe our principal advantage is the unique
mechanism of action of Ampligen(R) on the immune system, we cannot assure that
we will be able to compete.


32
ALFERON N Injection(R).  Many potential  competitors are among the largest
pharmaceutical companies in the world, are well known to the public and the
medical community, and have substantially greater financial resources, product
development, and manufacturing and marketing capabilities than we have. Alferon
N Injection(R) currently competes with Schering's injectable recombinant alpha
interferon product (INTRON(R) A) for the treatment of genital warts. 3M
Pharmaceuticals also received FDA approval for its immune-response modifier,
Aldara(R), a self-administered topical cream, for the treatment of external
genital and perianal warts. Alferon N Injection(R) also competes with surgical,
chemical, and other methods of treating genital warts. We cannot assess the
impact products developed by our competitors, or advances in other methods of
the treatment of genital warts, will have on the commercial viability of Alferon
N Injection(R). If and when we obtain additional approvals of uses of this
product, we expect to compete primarily on the basis of product performance. Our
potential competitors have developed or may develop products (containing either
alpha or beta interferon or other therapeutic compounds) or other treatment
modalities for those uses. In the United States, three recombinant forms of beta
interferon have been approved for the treatment of relapsing-remitting multiple
sclerosis. There can be no assurance that, if we are able to obtain regulatory
approval of Alferon N Injection(R) for the treatment of new indications, we will
be able to achieve any significant penetration into those markets. In addition,
because certain competitive products are not dependent on a source of human
blood cells, such products may be able to be produced in greater volume and at a
lower cost than Alferon N Injection(R). Currently, our wholesale price on a per
unit basis of Alferon N Injection(R) is higher than that of the competitive
recombinant alpha and beta interferon products.

General. Other companies may succeed in developing products earlier than
we do, obtaining approvals for such products from the FDA more rapidly than we
do, or developing products that are more effective than those we may develop.
While we will attempt to expand our technological capabilities in order to
remain competitive, there can be no assurance that research and development by
others or other medical advances will not render our technology or products
obsolete or non-competitive or result in treatments or cures superior to any
therapy we develop.

Possible side effects from the use of Ampligen(R) or Alferon N Injection(R)
could adversely affect potential revenues and physician/patient acceptability of
our product.

Ampligen(R). We believe that Ampligen(R) has been generally well tolerated
with a low incidence of clinical toxicity, particularly given the severely
debilitating or life threatening diseases that have been treated. A mild
flushing reaction has been observed in approximately 15% of patients treated in
our various studies. This reaction is occasionally accompanied by a rapid heart
beat, a tightness of the chest, urticaria (swelling of the skin), anxiety,
shortness of breath, subjective reports of "feeling hot," sweating and nausea.
The reaction is usually infusion-rate related and can generally be controlled by
slowing the infusion rate. Other adverse side effects include liver enzyme level
elevations, diarrhea, itching, asthma, low blood pressure, photophobia, rash,
transient visual disturbances, slow or irregular heart rate, decreases in
platelets and white blood cell counts, anemia, dizziness, confusion, elevation
of kidney function tests, occasional temporary hair loss and various flu-like
symptoms, including fever, chills, fatigue, muscular aches, joint pains,
headaches, nausea and vomiting. These flu-like side effects typically subside
within several months. One or more of the potential side effects might deter
usage of Ampligen(R) in certain clinical situations and therefore, could
adversely affect potential revenues and physician/patient acceptability of our
product.


33
Alferon  N  Injection(R).  At  present,  Alferon  N  Injection(R)  is only
approved for the intralesional (within the lesion) treatment of refractory or
recurring external genital warts in adults. In clinical trials conducted for the
treatment of genital warts with Alferon N Injection(R), patients did not
experience serious side effects; however, there can be no assurance that
unexpected or unacceptable side effects will not be found in the future for this
use or other potential uses of Alferon N Injection(R) which could threaten or
limit such product's usefulness.

We may be subject to product liability claims from the use of Ampligen(R),
Alferon N Injection(R), or other of our products which could negatively affect
our future operations.

We face an inherent business risk of exposure to product liability claims
in the event that the use of Ampligen(R) or other of our products results in
adverse effects. This liability might result from claims made directly by
patients, hospitals, clinics or other consumers, or by pharmaceutical companies
or others manufacturing these products on our behalf. Our future operations may
be negatively affected from the litigation costs, settlement expenses and lost
product sales inherent to these claims. While we will continue to attempt to
take appropriate precautions, we cannot assure that we will avoid significant
product liability exposure. Although we currently maintain product liability
insurance coverage, there can be no assurance that this insurance will provide
adequate coverage against Ampligen(R) and/or Alferon N Injection(R) product
liability claims. A successful product liability claim against us in excess of
Ampligen(R)'s $1,000,000 in insurance coverage; $3,000,000 in aggregate, or in
excess of Alferon N Injection(R)'s $5,000,000 in insurance coverage; $5,000,000
in aggregate; or for which coverage is not provided could have a negative effect
on our business and financial condition.


The loss of Dr. William A. Carter's services could hurt our chances for success.

Our success is dependent on the continued efforts of Dr. William A. Carter
because of his position as a pioneer in the field of nucleic acid drugs, his
being the co-inventor of Ampligen(R), and his knowledge of our overall
activities, including patents and clinical trials. The loss of Dr. Carter's
services could have a material adverse effect on our operations and chances for
success. We have secured key man life insurance in the amount of $2,000,000 on
the life of Dr. Carter and we have an employment agreement with Dr. Carter that,
as amended, runs until December 31, 2010. However, Dr. Carter has the right to
terminate his employment upon not less than 30 days prior written notice. The
loss of Dr. Carter or other personnel, or the failure to recruit additional
personnel as needed could have a materially adverse effect on our ability to
achieve our objectives.

Uncertainty of health care reimbursement for our products.

Our ability to successfully commercialize our products will depend, in
part, on the extent to which reimbursement for the cost of such products and
related treatment will be available from government health administration
authorities, private health coverage insurers and other organizations.
Significant uncertainty exists as to the reimbursement status of newly approved
health care products, and from time to time legislation is proposed, which, if
adopted, could further restrict the prices charged by and/or amounts
reimbursable to manufacturers of pharmaceutical products. We cannot predict
what, if any, legislation will ultimately be adopted or the impact of such
legislation on us. There can be no assurance that third party insurance
companies will allow us to charge and receive payments for products sufficient
to realize an appropriate return on our investment in product development.


34
There are  risks of  liabilities  associated  with  handling  and  disposing  of
hazardous materials.

Our business involves the controlled use of hazardous materials,
carcinogenic chemicals, flammable solvents and various radioactive compounds.
Although we believe that our safety procedures for handling and disposing of
such materials comply in all material respects with the standards prescribed by
applicable regulations, the risk of accidental contamination or injury from
these materials cannot be completely eliminated. In the event of such an
accident or the failure to comply with applicable regulations, we could be held
liable for any damages that result, and any such liability could be significant.
We do not maintain insurance coverage against such liabilities.

Risks Associated With an Investment in Our Common Stock

We reported material weaknesses in our internal control over financial reporting
that, if not remedied, could adversely affect our internal controls.

In connection with the review of our internal control over financial reporting
as of December 31, 2005, it was determined that the accounting principles
applied to certain features of our convertible debentures, the valuation of
debenture related and other common stock warrants dating back to 2003 were
inaccurately reflected in our interim financial statements through 2003 and 2005
and our annual financial statements for the years ended December 31, 2003 and
2004. Our processes and procedures related to the preparation and audit of the
quarterly and annual financial statements were not adequate to ensure that the
financials were prepared in accordance with generally accepted accounting
principles. While the result of applying the proper accounting principles
decreased our net loss per share by only $0.02 and $0.01 for the years ended
December 31, 2003 and 2004, respectively we consider our accounting review
process to be a material weakness that resulted in a material misstatement to
our consolidated financial statements.


We have taken and plan to take, during 2006, additional steps to remediate these
internal control weaknesses. In March 2006, we increased the time allocated by
our financial consultants with regards to remediate these disclosed internal
control weaknesses and spend additional time monitoring our internal controls on
an ongoing basis. Notwithstanding the foregoing, the measures we have taken and
any future measures to remediate the internal control weaknesses reported that
we may take, we may not be able to effectively maintain effective internal
control over financial reporting in the future. In addition, additional
deficiencies in our internal controls may be discovered in the future. Any
failure to remediate the reported material weakness or to implement new or
improved controls, or difficulties encountered in their implementation, could
harm our operating results, cause us to fail to meet our reporting obligations
or result in material misstatements in our financial statements. Any such
failure also could affect the ability of our management to certify in our 2006
Form 10-K and 10-Q that our internal controls are effective when it provides an
assessment of our internal control over financial reporting, and could affect
the results of our independent registered public accounting firm's related
attestation report regarding our management's assessment. Inferior internal
controls could also cause investors to lose confidence in our reported financial
information, which could have a negative effect on the trading price of our
securities.


35
The market price of our stock may be adversely affected by market volatility.

The market price of our common stock has been and is likely to be
volatile. In addition to general economic, political and market conditions, the
price and trading volume of our stock could fluctuate widely in response to many
factors, including:

o announcements of the results of clinical trials by us or our
competitors;

o adverse reactions to products;

o governmental approvals, delays in expected governmental approvals or
withdrawals of any prior governmental approvals or public or
regulatory agency concerns regarding the safety or effectiveness of
our products;

o changes in U.S. or foreign regulatory policy during the period of
product development;

o developments in patent or other proprietary rights, including any
third party challenges of our intellectual property rights;

o announcements of technological innovations by us or our competitors;

o announcements of new products or new contracts by us or our
competitors;

o actual or anticipated variations in our operating results due to the
level of development expenses and other factors;

o changes in financial estimates by securities analysts and whether
our earnings meet or exceed the estimates;

o conditions and trends in the pharmaceutical and other industries;
new accounting standards; and

o the occurrence of any of the risks described in these "Risk
Factors."

Our common stock is listed for quotation on the American Stock Exchange.
For the 12-month period ended December 31, 2005, the price of our common stock
has ranged from $1.25 to $3.70 per share. We expect the price of our common
stock to remain volatile. The average daily trading volume of our common stock
varies significantly. Our relatively low average volume and low average number
of transactions per day may affect the ability of our stockholders to sell their
shares in the public market at prevailing prices and a more active market may
never develop.

In the past, following periods of volatility in the market price of the
securities of companies in our industry, securities class action litigation has
often been instituted against companies in our industry. If we face securities
litigation in the future, even if without merit or unsuccessful, it would result
in substantial costs and a diversion of management attention and resources,
which would negatively impact our business.


36
Our stock price may be adversely  affected if a significant amount of shares are
sold in the public market.

As of March 24, 2006, approximately 899,772 shares of our common stock,
constituted "restricted securities" as defined in Rule 144 under the Securities
Act of 1933. Also, we have registered 22,331,890 shares issuable (i) to Fusion
Capital pursuant to the common stock purchase agreement with Fusion Capital;
(ii) upon conversion of approximately 135% of Debentures that we issued in 2003
and 2004; (iii) as payment of 135% of the interest on all of the Debentures;
(iv) upon exercise of 135% of certain Warrants; and (v) upon exercise of certain
other warrants. Registration of the shares permits the sale of the shares in the
open market or in privately negotiated transactions without compliance with the
requirements of Rule 144. To the extent the exercise price of the warrants is
less than the market price of the common stock, the holders of the warrants are
likely to exercise them and sell the underlying shares of common stock and to
the extent that the conversion price and exercise price of these securities are
adjusted pursuant to anti-dilution protection, the securities could be
exercisable or convertible for even more shares of common stock. We also may
issue shares to be used to meet our capital requirements or use shares to
compensate employees, consultants and/or directors. We are unable to estimate
the amount, timing or nature of future sales of outstanding common stock. Sales
of substantial amounts of our common stock in the public market could cause the
market price for our common stock to decrease. Furthermore, a decline in the
price of our common stock would likely impede our ability to raise capital
through the issuance of additional shares of common stock or other equity
securities.

The sale of our common stock to Fusion Capital may cause dilution and the sale
of the shares of common stock acquired by Fusion Capital and other shares
registered for selling stockholders could cause the price of our common stock to
decline.

The sale by Fusion Capital and other selling stockholders of our common
stock will increase the number of our publicly traded shares, which could
depress the market price of our common stock. Moreover, the mere prospect of
resales by Fusion Capital and other selling stockholders could depress the
market price for our common stock. The issuance of shares to Fusion Capital
under the common stock purchase agreement dated July 8, 2005, will dilute the
equity interest of existing stockholders and could have an adverse effect on the
market price of our common stock.

The purchase price for the common stock to be sold to Fusion Capital
pursuant to the common stock purchase agreement will fluctuate based on the
price of our common stock. All shares sold to Fusion Capital are freely
tradable. Fusion Capital may sell none, some or all of the shares of common
stock purchased from us at any time. We expect that the shares will be sold over
a period of in excess of 25 months from August 3, 2005. Depending upon market
liquidity at the time, a sale of shares under this offering at any given time
could cause the trading price of our common stock to decline. The sale of a
substantial number of shares of our common stock to Fusion Capital pursuant to
the purchase agreement, or anticipation of such sales, could make it more
difficult for us to sell equity or equity-related securities in the future at a
time and at a price that we might otherwise wish to effect sales.

Provisions of our Certificate of Incorporation and Delaware law could defer a
change of our management which could discourage or delay offers to acquire us.

Provisions of our Certificate of Incorporation and Delaware law may make
it more difficult for someone to acquire control of us or for our stockholders
to remove existing management, and might discourage a third party from offering
to acquire us, even if a change in control or in management would be beneficial
to our stockholders. For example, our Certificate of Incorporation allows us to
issue shares of preferred stock without any vote or further action by our
stockholders. Our Board of Directors has the authority to fix and determine the
relative rights and preferences of preferred stock. Our Board of Directors also
has the authority to issue preferred stock without further stockholder approval.
As a result, our Board of Directors could authorize the issuance of a series of
preferred stock that would grant to holders the preferred right to our assets
upon liquidation, the right to receive dividend payments before dividends are
distributed to the holders of common stock and the right to the redemption of
the shares, together with a premium, prior to the redemption of our common
stock. In this regard, in November 2002, we adopted a stockholder rights plan
and, under the Plan, our Board of Directors declared a dividend distribution of
one Right for each outstanding share of Common Stock to stockholders of record
at the close of business on November 29, 2002. Each Right initially entitles
holders to buy one unit of preferred stock for $30.00. The Rights generally are
not transferable apart from the common stock and will not be exercisable unless
and until a person or group acquires or commences a tender or exchange offer to
acquire, beneficial ownership of 15% or more of our common stock. However, for
Dr. Carter, our chief executive officer, who already beneficially owns 9.4% of
our common stock, the Plan's threshold will be 20%, instead of 15%. The Rights
will expire on November 19, 2012, and may be redeemed prior thereto at $.01 per
Right under certain circumstances.

Because the risk factors  referred to above could cause actual  results or
outcomes to differ materially from those expressed in any forward-looking
statements made by us, you should not place undue reliance on any such
forward-looking statements. Further, any forward-looking statement speaks only
as of the date on which it is made and we undertake no obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the date on which such statement is made or reflect the occurrence of
unanticipated events. New factors emerge from time to time, and it is not
possible for us to predict which will arise. In addition, we cannot assess the
impact of each factor on our business or the extent to which any factor, or
combination of factors, may cause actual results to differ materially from those
contained in any forward-looking statements. Our research in clinical efforts
may continue for the next several years and we may continue to incur losses due
to clinical costs incurred in the development of Ampligen(R) for commercial
application. Possible losses may fluctuate from quarter to quarter as a result
of differences in the timing of significant expenses incurred and receipt of
licensing fees and/or cost recovery treatment revenues in Europe, Canada and in
the United States.

ITEM 1B. Unresolved Staff Comments.

None.

ITEM 2. Properties.

We currently lease our headquarters located in Philadelphia, Pennsylvania
consisting of a suite of offices of approximately 15,000 square feet. We also
currently own, occupy and use our New Brunswick, New Jersey laboratory and
production facility that we acquired from ISI. These facilities consist of two
buildings located on 2.8 acres. One building is a two story facility consisting
of a total of 31,300 square feet. This facility contains offices, laboratories,
production space and shipping and receiving areas. It is also contains space
designated for research and development, our pharmacy, packaging, quality
assurance and quality control laboratories. Building Two has 11,670 square feet
consisting of offices, laboratories and warehouse space. The property has
parking space for approximately 100 vehicles.


38
In 2005, we initiated the transfer of Ampligen(R) raw materials production
to our own facilities has obvious advantages with respect to overall control of
the manufacturing procedure of Ampligen(R)'s raw materials, keeping costs down
and controlling regulatory compliance issues (other parts of the of our 43,000
sq. ft. wholly owned FDA approved facility are already in compliance for Alferon
N Injection(R) manufacture). This will also allow us to obtain Ampligen(R) raw
materials on a more consistent manufacturing basis. As of December 31, 2005, we
have capitalized approximately $821,000 towards the construction and
installation of this production line at our New Jersey facility. The anticipated
completion date for the facility is May 2006 with the first lot of Ampligen(R)
raw material being produced in the second quarter 2006. We estimate the total
cost of establishing this production line to be some $1,900,000, including
modifications to our New Brunswick facility. This polymer production line will
have the capacity to produce up to four kilograms per week, or 100 kilograms per
year which should allow us to manufacture up to one-half million 400 mg doses
per year.

Our lease on the Rockville facility expired in June 2005 and we completed
the move of our laboratory and equipment to our New Brunswick facility.
Consolidation of this laboratory with our existing laboratory in New Brunswick
will provide economical benefit. With the consolidation complete, it is our
belief that the consolidated facility will enable us to meet our requirements
for planned clinical trials and treatment protocols for the foreseeable future.



ITEM 3. Legal Proceedings.

On September 30, 1998, we filed a multi-count complaint against Manuel P.
Asensio, Asensio & Company, Inc. ("Asensio"). The action included claims of
defamation, disparagement, tortuous interference with existing and prospective
business relations and conspiracy, arising out of Asensio's false and defamatory
statements. The complaint further alleged that Asensio defamed and disparaged us
in furtherance of a manipulative, deceptive and unlawful short-selling scheme in
August and September, 1998. In 1999, Asensio filed an answer and counterclaim
alleging that in response to Asensio's strong sell recommendation and other
press releases, we made defamatory statements about Asensio. We denied the
material allegations of the counterclaim. In July 2000, following dismissal in
federal court for lack of subject matter jurisdiction, we transferred the action
to the Pennsylvania State Court. In March 2001, the defendants responded to the
complaints as amended and a trial commenced on January 30, 2002. A jury verdict
disallowed the claims against the defendants for defamation and disparagement
and the court granted us a directed verdict on the counterclaim. On July 2, 2002
the Court entered an order granting us a new trial against Asensio for
defamation and disparagement. Thereafter, Asensio appealed the granting of a new
trial to the Superior Court of Pennsylvania. The Superior Court of Pennsylvania
has denied Asensio's appeal. Asensio petitioned the Supreme Court of
Pennsylvania for allowance of an appeal, which was denied. We now anticipate the
scheduling of a new trial against Asensio for defamation and disparagement in
the Philadelphia Common Pleas Court.

In June 2002, a former ME/CFS clinical trial patient and her husband filed
a claim in the Superior Court of New Jersey, Middlesex County, against us, one
of our clinical trial investigators and others alleging that she was harmed in
the ME/CFS clinical trial as a result of negligence and breach of warranties. On
June 25, 2004 all claims against us were dismissed with prejudice. The former
ME/CFS clinical trial patient and her husband have now appealed the dismissal of
their claims to the New Jersey Superior Court, Apellate Division, upheld the
dismissal of all claims against us and the matter is now concluded.


39
In June 2002, a former  ME/CFS  clinical  trial patient in Belgium filed a
claim in Belgium, against Hemispherx Biopharma Europe, NV/SA, our Belgian
subsidiary, and one of our clinical trial investigators alleging that she was
harmed in the Belgium ME/CFS clinical trial as a result of negligence and breach
of warranties. We believe the claim is without merit and we are defending the
claim against us through our product liability insurance carrier.

In December 2004, we filed a multicount complaint in federal court
(Southern District of Florida) against a conspiratorial group seeking to
illegally manipulate our stock for purposes of bringing about a hostile takeover
of Hemispherx. The lawsuit alleges that the conspiratorial group commenced with
a plan to seize control of our cash and proprietary assets by an illegal
campaign to drive down our stock price and publish disparaging reports on our
management and current fiduciaries. The lawsuit seeks monetary damages from each
member of the conspiratorial group as well as injunctions preventing further
recurrences of their misconduct. The conspiratorial group includes Bioclones, a
privately held South African Biopharmaceutical company that collaborated with
us, and Johannesburg Consolidated Investments, a South African corporation,
Cyril Donninger, R. B. Kebble, H. C. Buitendag, Bart Goemaere, and John Doe(s).
Bioclones, Johannesburg Consolidated Investments, Cyril Donninger, R. B. Kebble
and H.C. Buitendag filed a motion to dismiss the complaint, which was granted by
the court. We are in the process of appealing this decision to the 11th federal
circuit court of appeals.

On January 10, 2005, we initiated a multicount lawsuit in the United
States District Court for the Eastern District of Pennsylvania seeking
injunctive relief and damages against a conspiratorial group, many of whom are
foreign nationals or companies located outside the United States alleging that
the conspiratorial group has engaged in secret meetings, market manipulations,
fraudulent misrepresentations, utilization of foreign accounts and foreign
secrecy laws all in furtherance of an illegal scheme to take over Hemispherx and
enrich themselves at the expense of Hemispherx's public shareholders. On
February 18, 2005 we filed an amended complaint in the same lawsuit joining
Redlabs, USA, Inc. as a defendant with the existing defendants R.E.D.
Laboratories, N.V./S.A., Bart Goemaere, Jan Goemaere, Dr. Kenny De Meirleir,
Kenneth Schepmans, Johan Goossens, Lieven Vansacker and John Does. Pursuant to
an agreement in which R.E.D. Laboratories, N.V./S.A. and Dr. Kenny DeMeirleir
agreed not to participate in a hostile takeover of Hemispherx for a period of
five years, R.E.D. Laboratories, N.V./S.A. and Dr. Kenny DeMeirleir have been
dismissed as defendants in the litigation. The litigation is proceeding against
the remaining defendants.

ITEM 4. Submission of Matters to a Vote of Security Holders.

No matters were submitted to a vote of the security holders during the
last quarter of the year ended December 31, 2005.

PART II

ITEM 5. Market for Registrant's Common Equity, Related Stockholder Matters and
Issuer Purchases of Equity Securities

In 2005 we issued 6,632,389 shares of common stock consisting of 1)
1,614,628 shares for debt repayment, debt conversion and interest payments
related to the October 2003, January 2004 and July 2004 Convertible Debentures;
2) 343,995 shares in payment of services rendered and 3) 4,673,766 shares issued
pursuant to the Fusion Capital Equity Funding Agreement.

The foregoing issuances of securities were private transactions and exempt
from registration under section 4(2) of the Securities Act and/or regulation D
rule 506 promulgated under the Securities Act. These securities have been or
will be registered with the SEC.

Since October 1997 our common stock has been listed and traded on the
American Stock Exchange ("AMEX") under the symbol HEB. The following table sets
forth the high and low list prices for our Common Stock for the last two fiscal
years as reported by the AMEX. Such prices reflect inter-dealer prices, without
retail markup, markdowns or commissions and may not necessarily represent actual

On March 24, 2006, the last sale price for our common stock on the AMEX
was $3.78 per share.

We have not paid any dividends on our Common Stock in recent years. It is
management's intention not to declare or pay dividends on our Common Stock, but
to retain earnings, if any, for the operation and expansion of our business.

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

The following discussion and analysis is related to our financial
condition and results of operations for the three years ended December 31, 2005.
This information should be read in conjunction with Item 6 - "Selected Financial
Data" and our consolidated financial statements and related notes thereto
beginning on F-1 of this Form 10-K.

Statement of Forward-Looking Information

Certain statements in the section are "forward-looking statements." You
should read the information before Item 1B above, "Special Note" Regarding
Forward-Looking Statements" for more information about our presentation of
information.

Background

We have reported net income only from 1985 through 1987. Since 1987, we
have incurred, as expected, substantial operating losses due to our conducting
clinical testing.

In the course of almost three decades, we have established a strong
foundation of laboratory, pre-clinical and clinical data with respect to the
development of nucleic acids to enhance the natural antiviral defense system of
the human body and the development of therapeutic products for the treatment of
chronic diseases. Our strategy is to obtain the required regulatory approvals
which will allow the progressive introduction of Ampligen(R) (our proprietary
drug) for treating Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome
("ME/CFS"), HIV, Hepatitis C ("HCV") and Hepatitis B ("HBV") in the U.S.,
Canada, Europe and Japan. In 2004, we completed a phase III clinical trial in
the U.S. for use of Ampligen(R) in treatment of ME/CFS and are in the process of
assembling and analyzing the obtained data preparatory to completing and filing
a New Drug Application with the FDA. We are also testing Ampligen(R) in Phase
IIb Clinical Trials in the U.S. for the treatment of newly emerging multi-drug
resistant HIV, and for the induction of cell mediated immunity in HIV patients
that are under control using potentially toxic drug cocktails.

43
Our  proprietary   drug  technology   utilizes   specifically   configured
ribonucleic acid ("RNA") and is protected by more than 100 patents worldwide,
with over 9 additional patent applications pending to provide further
proprietary protection in various international markets. Certain patents apply
to the use of Ampligen(R) alone and certain patents apply to the use of
Ampligen(R) in combination with certain other drugs. Some compositions of matter
patents pertain to other new RNA compounds, which have a similar mechanism of
action.

In March 2003 we obtained from Interferon Sciences, Inc. ("ISI") all of
its raw materials, work-in-progress and finished product Alferon N Injection(R),
together with a limited license to sell Alferon N Injection(R), a natural alpha
interferon that has been approved for commercial sale for the intralesional
treatment of refractory or recurring external condylomata acuminata ("genital
warts") in patients 18 years of age or older in the United States. In March
2004, we acquired from ISI the balance of ISI's rights to its product as well as
ISI's production facility. We are marketing the Alferon N Injection(R) in the
United States through sales facilitated via third party agreements.
Additionally, we intend to implement studies testing the efficacy of Alferon N
Injection(R) in multiple sclerosis and other chronic viral diseases. In this
regard, the FDA recently authorized a Phase II clinical study designed to
investigate the activity and safety of Alferon(R) LDO in early stage HIV
positive patients.

We were incorporated in Maryland in 1996 under the name HEM research,
Inc., and originally served as a supplier of research support products. Our
business was redirected in the early 1980's to the development of nucleic acid
pharmaceutical technology and the commercialization of RNA drugs. We were
reincorporated in Delaware and changed our name to Hem Pharmaceutical Corp. in
1991 and to Hemispherx Biopharma, Inc., in June 1995. We have three domestic
subsidiaries BioPro Corp., BioAegean Corp., and Core BioTech Corp., all of which
are incorporated in Delaware. Our foreign subsidiaries include Hemispherx
Biopharma Europe N.V./S.A. established in Belgium in 1998 and Hemispherx
Biopharma Europe S.A. incorporated in Luxembourg in 2002.

Restatements

(a) On March 29, 2006, after doing additional analysis on guidelines set forth
in EITF 00-27: Application of Issue No. 98-5 to Certain Convertible
Instruments, it was determined that the accounting treatment for the March
2003, July 2003, October 2003, January 2004 and July 2004 Debentures
(collectively, the "Debentures") was inaccurately reflected in the
financial statements for the quarters and years ended included in our
Annual Report on Form 10-K for the years ended December 31, 2004 and 2003,
and for the quarterly periods ended March 31, 2003, June 30, 2003,
September 30, 2003, March 31, 2004, June 30, 2004, September 30, 2004,
March 31, 2005, June 30, 2005 and September 30, 2005, included within our
Quarterly Reports on Form 10-Q and that, therefore, a restatement of our
financial statements for the periods referenced above was required. In
connection with the initial recording of the Debentures mentioned above,
it was originally determined that the discount related to the embedded
conversion features and warrant issuances calculated at fair value was
approximately $1,607,000, $2,724,000, $2,879,000, $2,272,000 and
$1,260,000 for the March 2003, July 2003, October 2003, January 2004 and
July 2004 Debentures, respectively. The discount derived from determining
the fair value of the embedded conversion feature and warrant issuances is
amortized to financing costs over the life of the debenture or charged to
earnings on the earlier conversion thereof. To properly account for the
initial calculation of the discount, we determined, under guidance from
EITF 00-27: Application of Issue No. 98-5 to Certain Convertible
Instruments, the debt discount should be restated for the March 2003, July
2003, October 2003, January 2004 and July 2004 Debentures to $2,098,000,
$2,280,000, $3,177,000, $1,998,000 and $628,000, respectively. The total
impact of this restatement on our statement of operations was to decrease
the net loss for the year ended December 31, 2004 by $382,000 or $0.01 per
share and an increase in net loss of $301,000 or $0.01 per share for the
period ended December 31, 2003.

44
(b)   On March 29, 2006, it was determined that the accounting treatment for the
investment banking fees paid to Cardinal Capital, LLC ("Cardinal") in
connection with the Debenture issuances was inaccurately reflected in the
financial statements for the quarters and years ended included in our
Annual Report on Form 10-K for the years ended December 31, 2004 and 2003,
and for the quarterly periods ended March 31, 2003, June 30, 2003,
September 30, 2003, March 31, 2004, June 30, 2004, September 30, 2004,
March 31, 2005, June 30, 2005 and September 30, 2005, included within our
Quarterly Reports on Form 10-Q and that, therefore, a restatement of our
financial statements for the periods referenced above was required. In
connection with the initial recording of the Debentures mentioned above,
it was originally determined that the fair value of the warrants issued as
investment banking fees paid to Cardinal Securities, LLC, be accounted for
as a discount to the underlying Debentures and be amortized over the life
of the debenture or charged to earnings on the earlier conversion thereof.
These investment banking fees should have been capitalized as an asset on
the balance sheet and amortized over the life of the debenture or charged
to earnings on the earlier conversion thereof. In addition, our
calculation of the fair value of the warrants issued to Cardinal as part
of the Debenture issuances as a discount to the Debenture was determined
to be overstated at the time of issuance. The total impact of this
restatement on our statement of operations was to decrease the net loss
for the year ended December 31, 2004 by $460,000 or $.01 and an increase
to the net loss for the year ended December 31, 2003 of $138,000 or $0.00
per share.

(c) On March 29, 2006, after doing additional analysis on guidelines set forth
in EITF 00-27: Application of Issue No. 98-5 to Certain Convertible
Instruments, it was determined that the accounting treatment for the
conversion price reset on the July 2003, January 2004 and July 2004
debentures was inaccurately reflected in the financial statements for the
quarters and years ended included in our Annual Report on Form 10-K for
the years ended December 31, 2004 and 2003, and for the quarterly periods
ended September 2003, March 31, 2004, June 30, 2004, September 30, 2004,
March 31, 2005, June 30, 2005 and September 30, 2005, included within our
Quarterly Reports on Form 10-Q and that, therefore, a restatement of our
financial statements for the periods referenced above was required. A
conversion price reset was triggered on the July 2003 Debenture upon the
issuance of the October 2003 Debenture. In addition, a conversion price
reset was triggered on both the January 2004 and July 2004 debentures upon
the closing of the August 2004 Private Placement (See Note 8 & 9 contained
within the consolidated financial statements contained herein for more
details on the resets). Under the previous accounting treatment, we did
not properly account for the conversion price resets on the July 2003,
January 2004 and July 2004 debentures. To properly account for the
conversion price resets, we determined, under guidance from EITF 00-27:
Application of Issue No. 98-5 to Certain Convertible Instruments, an
additional debt discount should have been recorded for the July 2003,
January 2004 and July 2004 Debentures of approximately $741,000, $915,000
and $632,000, respectively. The total impact of this restatement on our
statement of operations was to increase the net loss for the year ended
December 31, 2004 and 2003 by $1,037,000 and $58,000 or $0.02 and $0.00
per share, respectively.

45
(d)   On March 29, 2006, it was determined that the accounting treatment for the
warrant conversion price reset on the July 2009 Warrants (See Note 8
"January 2004 Debenture" within the consolidated financial statements
contained herein for more detail on this transaction) was inaccurately
reflected in the financial statements for the quarter and year ended
included in our Annual Report on Form 10-K for the year ended December 31,
2004, and for the quarterly period ended March 31, 2005, included within
our Quarterly Reports on Form 10-Q, and that, therefore, a restatement of
our financial statements for the periods referenced above was required.
The warrant price reset on the July 2009 Warrants was triggered upon the
closing of the August 2004 Private Placement and we recorded an additional
charge to earnings of $337,000 in 2005 upon the warrant price reset. This
additional charge to earnings in 2005 included $108,000 that pertained to
the quarter ended December 31, 2004. The total impact of this restatement
on our statement of operations was to increase the net loss for the year
ended December 31, 2004 by $108,000 or $0.00 per share.

(e) On March 29, 2006, it was determined that the accounting treatment for the
warrant conversion price reset on the May and June 2009 Warrants (See Note
8 within the consolidated financial statements contained herein for more
detail on this transaction) was inaccurately reflected in the financial
statements for the quarter and year ended included in our Annual Report on
Form 10-K for the year ended December 31, 2004, and for the quarterly
period ended March 31, 2005, included within our Quarterly Reports on Form
10-Q, and that, therefore, a restatement of our financial statements for
the periods referenced above was required. The warrant price reset on the
May and June 2009 Warrants was triggered upon the closing of the August
2004 Private Placement and we recorded an additional charge to earnings of
$1,359,000 in 2005 upon the warrant price resets. This additional charge
to earnings included $357,000 that pertained to 2004 as restated. The
total impact of this restatement on our statement of operations was to
increase the net loss for the year ended December 31, 2004 by $357,000 or
$0.01 per share.

(f) On March 29, 2006, it was determined that the accounting treatment for the
issuance of the June 2008 Warrants (See Note 8 within the consolidated
financial statements contained herein for more detail on this transaction)
was inaccurately reflected in the financial statements for the quarter and
year ended included in our Annual Report on Form 10-K for the year ended
December 31, 2003, and that, therefore, a restatement of our financial
statements for the periods referenced above was required. Under the
pervious accounting treatment, the June 2008 Warrants issued as incentive
for the March 2003 debenture holders to exercise prior warrant issuances
was not accounted for properly. To properly account for the issuance of
the additional warrants, we determined that we should have recorded a
lower debt discount of approximately $1,320,000. The total impact of this
restatement on our statement of operations was to decrease the net loss
for the year ended December 31, 2003 by $1,320,000 or $0.04 per share.

(g) On March 30, 2006, it was determined that the accounting treatment for the
issuance of the June 2009 Warrants (See Note 8 within the consolidated
financial statements contained herein for more detail on this transaction)
and warrants issued in conjunction with a debt modification were
inaccurately reflected in the financial statements for the quarters ended
June 30, 2004, through September 30, 2005 and the year ended included in
our Annual Report on Form 10-K for the year ended December 31, 2004, and
that, therefore, a restatement of our financial statements for the periods
referenced above were required. Under the pervious accounting treatment,
the initial issuance of the June 2009 Warrants and the warrants issued in
conjunction with the debt modification were not accounted for properly. To
properly account for the issuance of the additional warrants, we
determined that we should have recorded a lower charge to earnings of
approximately $1,667,000. The total impact of this restatement on our
statement of operations was to decrease the net loss for the year ended
December 31, 2004 by $1,677,000 or $0.04 per share.


As a result of the corrections of the errors described above, we restated our
financial statements included in this Annual Report on Form 10-K as follows:

We and our audit committee have discussed the above errors and adjustments with
our current independent registered public accounting firm and have determined
that a restatement is necessary for the periods described above. This Annual
Report on Form 10-K for the fiscal year ended December 31, 2005 reflects the
changes for the annual results for the years ended December 31, 2003 and
December 31, 2004. We will file our Quarterly Reports on Form 10-Q/A for the
quarterly periods ended March 31, 2004, June 30, 2004, September 30, 2004, March
31, 2005, June 30, 2005 and September 31, 2005, as soon as practicable in
connection with the restatements described above.

Result of Operations

Years Ended December 31, 2005 vs. 2004

49
Net loss

Our net loss of $13,213,000 for the year ended December 31, 2005 was down
46% compared to the same period in 2004. This reduction of $10,185,000 in loss
was primarily due to: 1) lower costs associated with non-cash financing charges
related to our convertible debentures and related warrants. These non-cash
financing costs were down $7,784,000 or 66% of the change in net loss from
period to period, 2) production/cost of goods sold expenditures were down
$1,721,000 due to increased expenditures during 2004 associated with ramping up
of the New Brunswick facility for further production of Alferon N Injection(R),
and 3) lower non-cash stock compensation expenses of approximately $1,617,000.
These lower expenses were slightly offset by an increase in research &
development ("R & D") costs during the current period of approximately
$1,302,000 mainly due to costs associated with the transfer of our technology to
Hollister-Stier, our contract manufacturer of Ampligen(R), and costs related to
the construction of our Ampligen(R) raw material production line within our New
Jersey facility. Certain costs related to our exploratory drug, Ampligen(R),
were expensed as R&D costs. Net losses per share were $(.26) for current period
versus $(.52) in the same period 2004.

The lower stock compensation expense noted above resulted from having a
limited number of shares of Common Stock authorized but not issued or reserved
for issuance upon conversion or exercise of outstanding convertible and
exercisable securities such as debentures, options and warrants prior to our
annual meeting of stockholders in September 2003. Prior to the meeting, to
permit consummation of the sale of the July 2003 Debentures and the related
warrants, Dr. Carter agreed that he would not exercise his warrants or options
unless and until our stockholders approve an increase in our authorized shares
of common stock. For Dr. Carter's waiver of his right to exercise certain
options and warrants prior to approval of the increase in our authorized shares,
we have agreed to compensate Dr. Carter.

Revenues

Revenues for the year ended December 31, 2005 were $1,083,000 as compared
to $1,229,000 for the same period in 2004. Alferon N Injection(R) sales were
down $140,000 or 13% while Ampligen(R) sold under the cost recovery clinical
program was down $6,000 or 3%. The decline in Alferon N Injection(R) sales can
be attributed to increased competition from rival products, specifically, 3M
Pharmaceutical's product Aldera. Ampligen(R) sold under the cost recovery
clinical program is a product of physicians and ME/CFS patients applying to us
to enroll in the program. After screening the patient's enrollment records, we
ship Ampligen(R) to the physician. A typical six-month treatment therapy costs
the patient about $7,200 for Ampligen(R). This program has been in effect for
many years and is offered as a treatment option to patients severely affected by
ME/CFS. As the name "cost recovery" implies, we have no gain or profit on these
sales. The benefits to us include 1) physicians and patients becoming familiar
with Ampligen(R) and 2) collection of clinical data relating to the patients'
treatment and results.

Production costs/cost of goods sold

Our costs for production/cost of goods sold were down $1,721,000 for the
year ended December 31, 2005 compared to the same period in 2004. $1,642,000 of
this decrease in production costs is primarily due to expenses incurred in 2004
related to preparing the New Brunswick facility for the production of Alferon N
Injection(R). There were no such costs in 2005. We are nearing completion of the
construction of the production line within our own facility in New Brunswick for
Ampligen(R) raw materials. We believe that this installation will increase
production capacity, improve efficiency and assure compliance with worldwide
drug manufacturing standards and processes.

50
Alferon  cost of goods sold for the year ended  December 31, 2005 and 2004
were $391,000 and $470,000, respectively. Since acquiring the right to
manufacture and market Alferon N Injection(R) in March 2003, we have converted
the work-in-progress inventory into finished goods as needed. This
work-in-progress inventory included three production lots totaling the
equivalent of approximately 55,000 vials (doses) at various stages of the
manufacturing process. Approximately 42,000 vials have been produced. Our
contractor, Hospira completed the labeling and packaging of approximately 12,000
vials of Alferon N Injection(R) inventory and these vials were released into
finished goods inventory in November 2005. Hospira gave notice that they will no
longer label and package Alferon N Injection(R) as they are seeking larger
production runs for cost efficiency purposes. We have identified two
manufacturers to replace Hospira and, on February 8, 2006, we executed a
Manufacturing and Safety Agreement with Hyaluron, Inc. ("Hyaluron") of
Burlington, Massachusetts, for the formulation, packaging and labeling of
Alferon N Injection(R). Pursuant to the Agreement, we will supply raw materials
in sufficient quantity and provide any pertinent information to the project.

We have started preliminary work to convert the third lot of approximately
13,000 vials to finished goods inventory with an anticipated completion date for
the third quarter 2006. By the first quarter 2007, we anticipate preparing new
Alferon N Injection(R) lots from blood leukocytes at our New Jersey facility.
Final formulation and packaging of Alferon N Injection(R) would be completed by
a third party contractor as noted above.

The installation of a Ampligen(R) raw material production line within our
New Brunswick facility should be completed and in production by May 2006. The
transfer of Ampligen(R) raw material production to our own facilities has
obvious advantages with respect to overall control of the manufacturing process,
keeping costs down and controlling regulatory compliance issues (other parts of
our 43,000 sq. ft. wholly owned FDA approved facility are already in compliance
for Alferon N Injection(R) manufacture). This will also allow us to obtain
Ampligen(R) raw materials on a more consistent and reliable basis. As of
December 31, 2005, we have capitalized approximately $821,000 towards the
construction and installation of this production line. The anticipated
completion date for the first lot of Ampligen(R) raw material being produced is
the second quarter 2006. We estimate the total cost of establishing this
production line to be some $1,900,000, including modifications to our New
Brunswick facility. This polymer production line will have the capacity to
produce up to four kilograms per week, or 100 kilograms per yeah which should
allow us to manufacture up to one-half million 400 mg doses per year. We have
identified three contract manufacturers to expand polymer manufacture, if
necessary, and obtained preliminary proposals from two and initiated discussions
with the third.

Research and Development costs

Overall research and development direct costs for the year ended December
31, 2005 and 2004 were $5,144,000 and $3,842,000, respectively. These costs in
2005 reflect the direct costs associated with our effort to develop our lead
product, Ampligen(R), as a therapy in treating chronic diseases and cancers as
well as on-going clinical trials involving patients with HIV. In addition, these
costs reflect direct costs incurred relating to the development of Alferon(R)
LDO (low dose oral interferon alfa-N3, human leukocyte derived). We have over
approximately 130,000 doses on hand of Alferon(R) LDO which have been prepared
for use in clinical trials treating patients affected with the SARS, Avian Flu
or other potentially emerging infectious diseases.

51
During 2005, we increased our clinical  staff by employing  several highly
trained individuals to focus on the preparation of our Ampligen(R) NDA filing.
The NDA filing is a very complex document and we are being meticulous in the
preparation of the document. Our clinical monitors and research assistants
completed the process of visiting the multiple clinical study sites around the
country for our AMP 516 study in January 2006. Our process included collecting
and auditing data generated at each of these sites. Since we are now
incorporating a larger sample of data from our previous trials for inclusion in
the NDA filing (see below for further details), our clinical monitors and
research assistants plan on visiting our sites associated with our AMP 511 study
in 2006 with the intention of collecting and auditing this additional data. All
data must be reviewed and checked to clarify any inconsistencies or inaccuracies
that turn up. Due to the human factor, these types of problems occur in all
clinical trials. These gaps and inconsistencies in data must be resolved with
the respective clinical investigators, while maintaining a clear record of
events which allows the FDA to conduct a meaningful audit of these records.

We believe that our AMP 516 ME/CFS Phase III clinical trial for use of
Ampligen(R) in the treatment of ME/CFS is the most comprehensive study ever
conducted in ME/CFS. This Phase III clinical trial, which was conducted over a
six-year period, involved an enrollment of more than 230 severely debilitated
ME/CFS patients and was conducted at twelve medical centers throughout the
United States. The study is serving as the basis for us to file a new drug
application with the FDA.

We had originally targeted a late 2004 filing date for this NDA for
Ampligen(R). In order to respond to recent changes in the regulatory environment
that place a greater emphasis on the safety and efficacy of all new experimental
drug candidates, we are now incorporating a larger sample of data from our
previous trials. The NDA filing will now include data accumulated from 45,000
administrations of the studied drug to approximately 750 ME/CFS patients. We
plan to complete and file the NDA before year end 2006.

The clinical development of the experimental therapeutic, Ampligen(R) for
ME/CFS was initiated approximately 16 years ago. To date federal health agencies
have yet to reach a consensus regarding various aspects of ME/CFS, including
parameters of "promising therapies" for ME/CFS and which aspects of ME/CFS are
anticipated to be "serious or life-threatening".

52
Over  its   developmental   history,   Ampligen(R)  has  received  various
designations, including Orphan Drug Product Certification (FDA), Emergency
(compassionate) Cost Recovery Sales Authorization (FDA) and "promising" clinical
outcome recognition based on the evaluation of certain summary clinical reports
(AHRQ, Agency Health Research Quality). However to date, the FDA has determined
it has yet to receive sufficient information to support the potential of
Ampligen(R) to treat a serious or life threatening aspect of ME/CFS. The
definition of the "seriousness of a condition", according to Guidance for
Industry documents published in July, 2004 is "a matter of judgment, but
generally based on its impact on such factors as survival, day-to-day
functioning, or the likelihood that the disease, if left untreated, will
progress from a less severe condition to a more serious one". The FDA has
recently requested a "complete and audited report of the Amp 516 study to
determine whether Ampligen(R) has a clinically meaningful benefit on a serious
or life threatening aspect of ME/CFS in order to evaluate whether the Amp 516
study results do or do not support a "fast track designation". The FDA has also
invited us to include a schedule for completion of all ME/CFS studies as well as
a proposed schedule for our NDA submission. Because we believe our ME/CFS
studies are complete, we intend to request a pre-NDA meeting to obtain advice on
preparing and submitting our NDA. At the same time we will continue with our
existing ongoing efforts to prepare a complete and audited report of our various
studies, including the well-controlled Amp 516 study. We are using our best
efforts to complete the requisite reports including the hiring of new staff and
various recognized expert medical/regulatory consultants, but can provide no
assurance as to whether the outcome of this large data collection and filing
process (approximately 750 patients, treated more than 45,000 times) will be
favorable or unfavorable, specifically with respect to the FDA's perspective. We
plan to use an independent contractor to file the NDA electronically to
facilitate the review by the FDA. Also, we can provide no guidance as to the
tentative date at which the compilation and filing of such data will be
complete, as significant factors are outside our control including, without
limitation, the ability and willingness of the independent clinical
investigators to complete the requisite reports at an acceptable regulatory
standard, the ability to collect overseas generated data, and the ability of
Hollister-Stier facilities (or the facilities of such other manufacturer as we
may retain in the event that we do not come to definitive terms with
Hollister-Stier) to interface with our own New Brunswick staff/facilities to
meet the manufacturing regulatory standards.

The timing of the FDA review process of the NDA is subject to the control
of the FDA and result in one of the following events; 1) approval to market
Ampligen(R) for use in treating ME/CFS patients, 2) require more research,
development, and clinical work, 3) approval to market as well as conduct more
testing, or 4) reject our NDA application. Given these variables, we are unable
to project when material net cash inflows are expected to commence from the sale
of Ampligen(R).

Our Amp 720 HIV study is a treatment using a Strategic Treatment
Interruption ("STI"). The patients' antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as mono-immunotherapy. Patients, who have completed
at least nine months of Ampligen(R) therapy, were able to stay off HAART for a
total STI duration with a mean time of 29.0 weeks whereas the control group,
which was also taken off HAART, but not given Ampligen(R), had earlier HIV
rebound with a mean duration of 18.7 weeks. Thus, on average, Ampligen(R)
therapy spared the patients excessive exposure to HAART, with its inherent
toxicities, for more than 11 weeks.

41 HIV patients have already participated in this 64 week study. The rate
of enrollment depends on patient availability and on other products being in
clinical trials for the treatment of HIV, causing competition for the same
patient population. At present, more than 18 FDA approved drugs for HIV
treatment competing for available patients. The length, and subsequently the
expense of these studies, will also be determined by an analysis of the interim
data, which will determine when completion of the ongoing Phase IIb is
appropriate and whether a Phase III trial will be conducted or not. In case a
Phase III study is required, the FDA might require a patient population
exceeding the current one which will influence the cost and time of the trial.
Accordingly, the number of "unknowns" is sufficiently great to be unable to
predict when, or whether, we may obtain revenues from our HIV treatment
indications.

With the threat of an avian influenza pandemic rising and health officials
warning that the virus could develop resistance to current flu treatments, the
pursuit of a cost-effective and complementary treatment to existing antivirals
and vaccines has become critical. This combination may permit the use of lower
dosages and fewer injections of the antivirals and vaccines used to combat avian
flu, thereby decreasing the cost of both immunization programs and treatment
programs for the full-blown disease.

53
In  antimicrobial  (antibacterial)  therapy,  which  is  the  best-studied
clinical model, synergistic drug combinations may result in curative
conditions/outcomes, often not observed when the single drugs are given alone.
In the case of avian influenza where global drug supplies are presumptively in
very limited supply relative to potential needs, therapeutic synergistic
combinations could not only affect the disease outcome, but also the number of
individuals able to access therapies.

In a recently reported study from a vaccine group in Japan, the
incorporation of poly I: poly C (dsRNA) into a nasal administration of a killed
influenza A preparation converted a poorly immunogenic response into a highly
efficacious vaccine in protection of mice from lethal infection from human
influenza A. Ampligen(R) is a dsRNA which currently is undergoing testing in the
animal model.

Recently, at the fourth annual Biodefense Research Meeting of the American
Society of Microbiology held in Washington, D.C., we presented results of
laboratory testing that showed our two investigational immunotherapeutics,
Ampligen(R) and Alferon(R), are potentially useful against H5N1, or avian flu,
virus. The pre-clinical research indicates that Ampligen(R), a specifically
configured double-stranded RNA, can provide cross-protection against avian flu
viral mutations as well as boost the effectiveness of Tamiflu and Relenza, the
only two drugs formally recognized for combating bird flu, up to 100 times.
Other lab tests, in healthy human volunteers, indicate that Alferon(R) LDO (Low
Dose Oral), a new delivery form of an anti-viral with prior regulatory approval
for a category of sexually transmitted diseases, can stimulate genes that induce
the production of interferon and other immune compounds, key building blocks in
the body's defense system. The studies were conducted in conjunction with the
National Institute of Infectious Diseases of Japan.

We have recently entered into an agreement with Defence R&D Canada,
Suffield ("DRDC Suffield"), an agency of the Canadian Department of National
Defence, to evaluate the antiviral efficacy of our experimental therapeutic
Ampligen(R) and Alferon(R) for protection against human respiratory influenza
virus infection in well validated animal models. DRDC Suffield is conducting
research and development of new drugs that could potentially become part of the
arsenal of existing antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the respiratory influenza
virus infection on a mouse-adapted strain of human influenza. DRDC Suffield has
already conducted extensive research in the use of liposome delivery technology
to enhance the antiviral activity of a closely-allied Ampligen(R) analogue, Poly
ICLC (an immunomodulating dsRNA) which is very similar to Ampligen(R). Results
suggest that ribo nucleic acid-based drugs have the ability to elicit protective
broad-spectrum antiviral immunity against various pathogenic viruses. Hence,
there is the potential for efficacy to be maintained against mutating strains of
an influenza virus. Liposomes, a carrier system for nucleic acid-based drugs,
have shown an ability to protect these drugs against in vivo degradation,
delivering them to intracellular sites of infection, thereby reducing any
toxicity and prolonging their therapeutic effectiveness. Protection can be
afforded for 21 days with two doses of dsRNA. It is believed that in humans with
active flu infection, Tamiflu, given twice daily, may ameliorate symptoms.

54
A  preclinical   study  was  initiated  in  June  2005,  to  determine  if
Ampligen(R) enhances the effectiveness of different drug combinations on avian
influenza. The preclinical study suggests a new, and potentially pivotal role of
double-stranded RNA ("dsRNA") therapeutics in improving the efficacy of the
present standards in care in both influenza prevention and treatment of acute
disease. The preclinical study is being conducted by research affiliates of the
National Institutes of Health at Utah State University to examine potential
therapeutic synergies with different drug combinations. The ongoing research is
comparing the relative protection conveyed by Tamiflu (oseltamivir, Roche) and
Relenza (Zanamivir, GlaxoSmithKline) with Ampligen(R) (dsRNA), alone and in
combination, against the avian flu virus (H5N1). Cell destruction was measured
in vitro using different drug combinations. Both drugs, given alone, were
effective in inhibiting cell destruction by avian influenza, but viral
suppression with the combination was greater than either drug alone. The overall
assessment is that there was improvement in cell protection when Ampligen(R) was
combined with oseltamivir carboxylate (Tamiflu) and Zanamivir (Relenza). Further
immediate experimental tests are planned.

Recently, Japanese researchers (Journal of Virology page 2910, 2005) have
found that dsRNAs increase the effectiveness of influenza vaccine by more than
300% and may also convey "cross-protection ability against variant viruses"
(mutated strains of influenza virus). In October 2005, we signed a research
agreement with the National Institute of Infectious Diseases, in Tokyo, Japan.
The collaboration, by Hideki Hasegawa, M.D., Ph.D., Chief of the Laboratory of
Infectious Disease Pathology, will assess our experimental therapeutic
Ampligen(R) as a co-administered immunotherapeutic to the Institution's nasal
flu vaccine.

In October 2005, we also engaged the Sage Group, Inc., a health care,
technology oriented, strategy and transaction advisory firm, to assist us in
obtaining a strategic alliance in Japan for the use of Ampligen(R) in treating
Chronic Fatigue Syndrome or CFS. In the past year leaders in the Japanese
medical community have established the Japanese Society of the Fatigue Science
and the Osaka City University Hospital opened the Fatigue Clinical Center as the
initial step in their Fatigue Research Project.

A clinical study has been approved by the Clinical Research Ethics
Committee of the Kowloon West Cluster at the Princess Margaret Hospital in Hong
Kong to evaluate the use of Alferon(R) LDO (Low Dose Oral Interferon Alfa-N3,
Human Leukocyte Derived) in normal volunteers and/or asymptomatic subjects with
exposure to a person known to have SARS. This study completed the dosing of ten
patients during the fourth quarter 2005 and we expect to complete analyzing the
results of this study in the coming months.

A clinical study to evaluate the use of Alferon(R) LDO in HIV infected
volunteers was initiated during the second quarter 2005 in Philadelphia, PA. The
study is currently being conducted at two sites, Drexel University and
Philadelphia FIGHT, a comprehensive AIDS service organization providing primary
care, consumer education, advocacy and research on potential treatments and
vaccines. The study is designed to determine whether Alferon(R) LDO can
resuscitate the broad-spectrum antiviral and immunostimulatory genes. The
initial patient enrolled in this study in July 2005 and, as of December 2005,
seven patients have enrolled and completed dosing. We are currently receiving
data from this study and we are in the process of analyzing the results. This
trial methodology may have implications for treating other emerging viruses such
as avian influenza (bird flu). Present production methods for vaccines involve
the use of millions of chicken eggs and would be slow to respond to an outbreak
according to a recently convened World Health Organization expert panel in
November 2004. Health officials are also concerned that bird flu could mutate to
cause the next pandemic and render present vaccines under development
ineffective.

55
In  September  2004,  we  commenced  a  clinical  trial  using  Alferon  N
Injection(R) to treat patients infected with the West Nile Virus. The infectious
Disease section of New York Queens Hospital and the Weill Medical College of
Cornell University are conducting this double-blinded, placebo controlled trial.
This study plans to enroll 60 patients as they become available. As of March 1,
2006, nine patients have entered this study. The CDC reports that 2,744 cases of
West Nile Virus have been reported in the US as of January 10, 2006, including
105 deaths.

We have completed the transfer and consolidation of our Rockville Quality
Assurance Lab and equipment into our New Brunswick facility. We believe this
newly consolidated lab will provide more efficiencies with regard to the quality
assurance needs for both Ampligen(R) and Alferon N Injection(R).

In connection with settling various manufacturing infractions previously
noted by the FDA, Schering entered into a "Consent Decree" with the FDA whereby,
among other things, it agreed to discontinue various contract (third party)
manufacturing activities at various facilities including its San Juan, Puerto
Rico, plant. Ampligen(R) (which was not involved in any of the cited
infractions) was produced at this Puerto Rico plant from year 2000-2004.
Operating under instructions from the Consent Decree, Schering has advised us
that it would no longer manufacture Ampligen(R) in this facility beyond 2004 and
would assist us in an orderly transfer of said activities to other non Schering
facilities.

On December 9, 2005, we executed a Supply Agreement with Hollister-Stier
Laboratories LLC of Spokane, Washington, for the contract manufacturing of
Ampligen(R) for a five year term. Pursuant to the agreement we will supply the
key raw materials and Hollister-Stier will formulate and bottle the Ampligen(R).
We paid $100,000 as a deposit in order to initiate the manufacturing project.
This deposit was expended as research and development in 2005. The achievement
of the initial objectives described in the agreement, in combination with our
polymer production facility under construction in New Brunswick, N.J., may
enable us to manufacture the raw materials for approximately 10,000 doses of
Ampligen(R) per week. We executed a confidentiality agreement with
Hollister-Stier; therefore, we commenced the transfer of our manufacturing
technology to Hollister-Stier. Currently, Hollister-Stier has completed two
pilot manufacturing runs of Ampligen(R) for stability testing.

We have identified two other cGMP production facilities in the United
States capable of manufacturing Ampligen(R). Engagement of either of these
facilities would provide back-up to Hollister-Stier and/or provide additional
production capacity if needed. We are reviewing proposals from these production
facilities and expect to act upon one or the other at the appropriate time.

General and Administrative Expenses

General and Administrative ("G&A") expenses for the years ended December
31, 2005 and 2004 were approximately $5,187,000 and $6,164,000, respectively.
The decrease in G&A expenses of $977,000 during this period is primarily due to
a non-cash stock compensation charge of $1,617,000 resulting from the issuance
of 1,450,000 warrants to purchase common stock at $2.20 per share to Dr. Carter
in 2003 that vested in the first quarter 2004. The warrants vested upon the
second ISI asset closing which occurred in March 17, 2005. Higher professional
fees, specifically legal costs, during 2005, slightly offset this decrease in
G&A as we initiated legal proceedings seeking injunction relief and damages
against conspiratorial group engaged in illegal activities to take over
Hemispherx and enrich themselves at the expense of our stockholders. Please see
Item 3. "Legal Proceedings" in Part I, above for more information.

56
Interest and Other Income

Interest and other income for the three months ended December 31, 2005 and
2004 totaled $831,000 and $49,000, respectively. The increase in interest and
other income during the year can primarily be attributed to the maturing of
marketable securities during the 2005 period. All funds in excess of our
immediate need are invested in short-term high quality securities. As described
in Note 3(f) to the accompanying financial statements, we have determined that
all obligations under the MOU with Fujisawa have been fulfilled; therefore,
other income of $241,000 has been recorded in this period.

Interest Expense and Financing Costs

Non-cash financing costs and interest expenses were approximately
$4,859,000 for the year ended December 31, 2005 versus $12,185,000 in charges
for the same period a year ago. Non-cash financing costs consist of the
amortization of debenture closing costs, the amortization of Original Issue
Discounts and the amortization of costs associated with beneficial conversion
features of our debentures and the fair value of the warrants relating to the
Debentures. These charges are reflected in the Consolidated Statements of
Operations under the caption "Financing Costs." The main reason for the decrease
in financing costs and interest expense of $7,780,000 or 64% can be attributed
to the aggregate total of these charges being reduced since 2004 due to
decreased amortization charges as well as charges related to the conversion of
debentures. Please see Note 8 in the consolidated financial statements contained
herein for more details on these transactions.

Years Ended December 31, 2004 (as restated) vs. 2003 (as restated)

During the year ended December 31, 2004, we 1) materially improved our
cash position, 2) completed the acquisition of our production facility in New
Brunswick, New Jersey, as well as, acquired all of ISI's rights to market
Alferon(R) N, 3) completed drug dosing in our Phase III AMP 516 ME/CFS clinical
trial and 4) continued our efforts to develop Ampligen(R)/Alferon(R) N. Our cash
position improved as a result of placing January and July 2004 6% convertible
debentures with an aggregate maturity value of $6,000,000 (gross proceeds of
$5,695,000) and the August 2004 private placement with select institutional
investors of approximately 3,617,000 shares of our common stock and warrants
producing $7,524,000 in gross proceeds. Completion of the drug dosing in the AMP
516 ME/CFS clinical trial in August 2004 allowed us to start the next step
towards completing data collection and analysis.

Net loss

Non-cash charges materially affected our net losses for the years ended
December 31, 2004 and 2003. Our losses as restated, of $23,398,000 for the year
ended December 31, 2004, include non-cash financing charges of $11,801,000 and
non-cash charges of $2,000,000 for stock compensation expenses. The losses for
the same period, as restated, in 2003 of $13,993,000 included non-cash financing
charges of $6,568,000. This $9,405,000 increase in net operating losses reflects
an increase of $5,233,000 in non-cash finance charges, $692,000 in research and
development expenses and $1,610,000 in production/cost of goods sold. The
increase in our research and development costs were the result of 1) costs
incurred in the development of a more efficient bottling manufacturing process
for Alferon N Injection(R), 2) vials abstracted from the third lot of Alferon N
Injection(R) inventory for research and development purposes, and 3) costs
associated with using Alferon N Injection(R) in a clinical trial to treat
patients infected with the West Nile Virus. Our production cost/cost of goods
sold increased due to 1) higher Alferon N Injection(R) sales, 2) costs related
to preparing our New Brunswick, NJ facility for the installation of the lab now
located in Rockville, MD, and 3) expanding production at our New Brunswick
facility to include Ampligen(R) raw material. The $2,000,000 for stock
compensation expense primarily consisted of $1,769,000 resulting from warrants
issued to Dr. Carter in 2003 that vested in the first quarter 2004. These
warrants vested upon the second ISI asset closing which occurred on March 17,
2004.

57
Revenues

Revenues for the year ended December 31, 2004 were $1,229,000 as compared
to revenues of $657,000 for the same period in 2003. Revenues for the year ended
December 31, 2004 from sales of Alferon(R) N totaled $1,050,000 versus $509,000
for the period of March 11, 2003, the date we acquired the rights to the
Alferon(R) N business from ISI, through December 31, 2003. Sales of Alferon(R) N
are anticipated to increase as we have more product available and intend to
expand our marketing/sales programs on an international basis. Revenues from our
ME/CFS cost recovery treatment programs principally underway in the U.S., Canada
and Europe were $179,000 for the year ended December 31, 2004 versus $148,000
for the year ended December 31, 2003. These clinical programs allow us to
provide Ampligen(R) therapy at our cost to severely debilitated ME/CFS patients.
Under this program the patients pay for the cost of Ampligen(R) doses infused.
These costs total approximately $7,200 for a 24-week treatment program.

We executed a Memorandum of Understanding (MOU) in January 2004 with
Astellas Pharma ("Astellas"), formally Fujisawa Deutschland GmbH, a major
pharmaceutical corporation, granting them an exclusive option for a limited
number of months to enter a Sales and Distribution Agreement with exclusive
rights to market Ampligen(R) for ME/CFS in Germany, Austria and Switzerland. The
MOU required us to file the full report on the results of our AMP 516 Clinical
Trial with Astellas by May 31, 2004. If the full report was not provided to
Astellas by May 31, 2004 and Astellas did not wish to exercise its option, we
would have been required to refund one half of the 400,000 Euro fee. We
submitted our initial report to Astellas on May 28, 2004 and responded to
subsequent inquiries for additional information. The option period ends 12 weeks
after the later of Astellas's review of the full report on the results of our
Amp 516 clinical trial and Astellas's meeting with three of the trial's
principal investigators. We received an initial fee of 400,000 Euros
(approximately $497,000 US). If we did not provide them with the full report by
December 31, 2004 and Astellas did not wish to exercise its option, we would be
required to refund the entire fee. On November 9, 2004, we and Fuji terminated
the MOU by mutual agreement. We did not agree on the process to be utilized in
certain European Territories for obtaining commercial approval for the sale of
Ampligen(R) in the treatment of patients suffering from Chronic Fatigue Syndrome
(CFS). Instead of a centralized procedure, and in order to obtain an earlier
commercial approval of Ampligen(R) in Europe, we have determined to follow a
decentralized filing procedure which was not anticipated in the MOU. We believe
that it now is in the best interest of our stockholders to potentially
accelerate entry into selected European markets whereas the original MOU
specified a centralized registration procedure. Pursuant to mutual agreement of
the parties we refunded 200,000 Euros to Astellas. We have recorded the
remaining 200,000 Euros as an accrued liability as of December 31, 2004. We are
currently holding the 200,000 Euros pending further developments in accordance
with the mutually agreed upon termination with Astellas. The Company has
determined that all obligations under the MOU with Astella's have been fulfilled
and, therefore, $241,000 was recorded in September 2005 as other income.

58
Production costs/cost of goods sold

Production costs for the year ended December 31, 2004 and 2003 were
$2,112,000 and $502,000, respectively. These costs reflect approximately
$470,000 for the cost of sales of Alferon N Injection(R) for the year ended
December 31, 2004. In addition, costs of sales for Alferon N Injection(R) for
the period March 11, 2003 (acquisition date of inventory from ISI) through
December 31, 2003 amounted to $240,000. The remaining production costs in 2004
represent expenditures associated with preparing the New Brunswick facility for
the installation of the lab now located in Rockville, MD and for further
production of Alferon N Injection(R) and Ampligen(R) raw materials. In August
2004, we released most of the second lot of product (approximately 13,000 vials)
to Abbott laboratories for bottling and realized approximately 12,000 vials of
Alferon(R) N. Some 3,000 of the remaining vials within this lot were held back
to be utilized in the development of a more compatible vial size for
manufacturing of Alferon N Injection(R). Our production and quality control
personnel in our New Brunswick, NJ facility are involved in the extensive
process of manufacturing and validation required by the FDA.

Research and Development costs

Overall research and development direct costs for the year ended December
31, 2004 were $3,842,000 as compared to $3,150,000 during the same period a year
earlier. These costs primarily reflect the direct costs associated with our
effort to develop our lead product, Ampligen(R), as a therapy in treating
chronic diseases and cancers as well as on-going clinical trials involving
patients with HIV. The primary reasons for the increase in research and
development costs of $692,000 for the year ended December 31, 2004 versus the
same period a year ago were primarily due to 1) costs incurred in the
development of a more efficient bottling manufacturing process for Alferon N
Injection(R), 2) vials abstracted from the third lot of Alferon N Injection(R)
inventory for research and development purposes, and 3) costs associated with
using Alferon N Injection(R) in a clinical trial to treat patients infected with
the West Nile Virus.

In 2004 we completed the double-blind segment of our AMP 516 ME/CFS Phase
III clinical trial for use of Ampligen(R) in the treatment of ME/CFS. Clinical
data on the primary endpoint exercise treadmill duration was presented at the
17th International Conference on Anti-viral Research in Tucson, AZ on May 3,
2004. The data showed that patients receiving Ampligen(R) for 40 weeks improved
exercise treadmill performance by a medically and statistically significant
amount compared to the Placebo group. New data was presented at the Interscience
Conference on Antimicrobial Agents and Chemotherapy on increases in exercise
capacity with Ampligen(R) and Placebo which were correlated with an improved
ability to utilize oxygen, so called, maximum oxygen consumption or (VO2max).
VO2max has been previously shown by others to be decreased with individuals with
CFS. An abnormal exercise stress test, including a low VO2max, could help
qualify CFS patients for disability under Social Security Administration rules.
Additional data on subset analyses showed that both Stratification cohorts
(those with baseline exercise treadmill duration greater than or less than nine
minutes) improved exercise capacity by over 6.5%, an amount considered medically
significant in other chronic diseases.

59
Ampligen(R)  is in two  Phase  IIb  studies  for the  treatment  of HIV to
overcome multi-drug resistance, virus mutation and toxicity associated with
current HAART therapies. One study, the AMP-719, is a Salvage Therapy, conducted
in the U.S. and evaluating the potential synergistic efficacy of Ampligen(R) in
multi-drug resistant HIV patients for immune enhancement. The second study, the
AMP-720, is a clinical trial designed to evaluate the effect of Ampligen(R)
under Strategic Treatment Intervention and is also conducted in the U.S.
Enrollment in the AMP 719 study is presently on hold as we focus our efforts on
the AMP 720 study.

ME/CFS

Over 230 patients have participated in our ME/CFS Phase III clinical
trial. In August 2004, the remaining patients completed drug dosing in the open
label segment (Stage II) of this Phase III protocol. We completed the randomized
placebo controlled phase (Stage I) of this study in February 2004 and have
started final data collection for the data analysis. This process includes
validation and quality assurance and should be completed by early 2005. As with
any experimental drug being tested for use in treating human diseases, the FDA
must approve the testing and clinical protocols employed and must render their
decision based on the safety and efficacy of the drug being tested. Historically
this is a long and costly process. Our ME/CFS AMP 516 clinical study is a Phase
III study, which based on favorable results, will serve as the basis for us to
file a new drug application with the FDA. The FDA review process could take
18-24 months and result in one of the following events; 1) approval to market
Ampligen(R) for use in treating ME/CFS patients, 2) required more research,
development, and clinical work, 3) approval to market as well as conduct more
testing, or 4)reject our application. Given these variables, we are unable to
project when material net cash inflows are expected to commence from the sale of
Ampligen(R).

HIV

The Amp 720 HIV study is a treatment using a Strategic Treatment
Interruption (STI). The patients' antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as mono-immunotherapy. Ampligen(R) is an experimental
immunotherapeutic designed to display both antiviral and immune enhancing
characteristics. Prolonged use of Highly Active Antiretroviral Therapy (HAART)
has been associated with long-term, potentially fatal, toxicities. The clinical
study AMP 720 is designed to address these issues by evaluating the
administration of our lead experimental agent, Ampligen(R), a double stranded
RNA drug acting potentially both as an immunomodulator and antiviral. Patients,
who have completed at least nine months of Ampligen(R) therapy, were able to
stay off HAART for a total STI duration with a mean time of 29.0 weeks whereas
the control group, which was also taken off HAART, but not given Ampligen(R),
had earlier HIV rebound with a mean duration of 18.7 weeks. Thus, on average,
Ampligen(R) therapy spared the patients excessive exposure to HAART, with its
inherent toxicities, for more than 11 weeks. As more patients are enrolled, the
related clinical costs will continue to increase with some offset to our overall
expenses due to the diminishing cost of the ME/CFS clinical trial. It is
difficult to estimate the duration or projected costs of these two clinical
trials due to the many variables involved, i.e.: patient drop out rate,
recruitment of clinical investigators, etc. The length of the study and costs
related to our clinical trials cannot be determined at this time as such will be
materially influenced by (a) the number of clinical investigators needed to
recruit and treat the required number of patients, (b) the rate of accrual of
patients and (c) the retention of patients in the studies and their adherence to
the study protocol requirements. Under optimal conditions, the cost of
completing the studies could be approximately $2.0 to $3.0 million. The rate of
enrollment depends on patient availability and on other products being in
clinical trials for the treatment of HIV, as there is competition for the same
patient population. At present, more than 18 FDA approved drugs for HIV
treatment compete for available patients. The length, and subsequently the
expense of these studies, will also be determined by an analysis of the interim
data, which will determine when completion of the ongoing Phase IIb is
appropriate and whether a Phase III trial be conducted or not. In case a Phase
III study is required; the FDA might require a patient population exceeding the
current one which will influence the cost and time of the trial. Accordingly,
the number of "unknowns" is sufficiently great to be unable to predict when, or
whether, we will complete this trial and/or obtain revenues from our HIV
treatment indications.

60
In  September,  2004  we  commenced  a  clinical  trial  using  Alferon  N
Injection(R) to treat patients infected with the West Nile Virus. The infectious
Disease section of New York Queens Hospital and the Weill Medical College of
Cornell University will be conducting this double-blinded, placebo controlled
trial. During 2004, over 2,000 human cases of West Nile Virus were reported in
40 states.

Manufacturing

In order to obtain Ampligen(R) raw materials of higher quality (GMP
certified) and on a more regular production basis, we have implemented
consolidation and transfer of relevant manufacturing operations into our New
Brunswick, New Jersey facility. This consolidation and transfer of manufacturing
operations has been implemented as a recent inspection of the Ribotech facility
in South Africa, our previous supplier of Ampligen(R) raw materials, indicated
that it did not, at present, meet the necessary GMP standards for a fully
certified commercial process. The transfer of Ampligen(R) raw materials
manufacture to our own facilities, while having obvious advantages with respect
to regulatory compliance (other parts of the 43,000 sq. ft. wholly owned
facility are already in compliance for Alferon(R) N manufacture), may delay
certain steps in the commercialization process, specifically a targeted NDA
filing.

In connection with settling various manufacturing infractions previously
noted by the FDA, Schering entered into a "Consent Decree" with the FDA whereby,
among other things, it agreed to discontinue various contract (third party)
manufacturing activities at various facilities including its San Juan, Puerto
Rico, plant. Ampligen(R) (which was not involved in any of the cited
infractions) was produced at this Puerto Rico plant from year 2000-2004.
Operating under instructions from the Consent Decree, Schering has recently
advised us that it would no longer manufacture Ampligen(R) in this facility at
the end of the applicable term (which is 4th quarter 2004) and would assist us
in an orderly transfer of said activities to other non Schering facilities. On
December 9, 2005, we executed a Supply Agreement with Hollister-Stier
Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for the contract
manufacturing of Ampligen(R) for a five year term. Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier will formulate and bottle
the Ampligen(R). In November 2005, we paid a $100,000 deposit upon executing the
agreement in order to initiate the manufacturing project. We recorded this
payment as a research and development cost in 2005. The achievement of the
initial objectives described in the agreement, in combination with our polymer
production facility under construction in New Brunswick, N.J., may enable us to
manufacture the raw materials for approximately 10,000 doses of Ampligen(R) per
week. We executed a confidentiality agreement with Hollister-Stier; therefore,
we commenced the transfer of our manufacturing technology to Hollister-Stier.
Currently, Hollister-Stier has completed two pilot manufacturing runs of
Ampligen(R) for stability testing.

61
We have  identified  two other cGMP  production  facilities  in the United
States capable of manufacturing Ampligen(R). Engagement of either of these
facilities would provide back-up to Hollister-Stier and/or provide additional
production capacity if needed. We are reviewing proposals from these production
facilities and expect to act upon one or the other at the appropriate time.

The purified drug concentrate utilized in the formulation of Alferon N
Injection(R) is manufactured in our New Brunswick, New Jersey facility and
Alferon N Injection(R) was formulated and packaged at a production facility
formerly owned and operated by Abbott Laboratories located in Kansas. Abbott
Laboratories has sold the facility to Hospira. Hospira recently completed the
production of 11,590 vials. Hospira is ceasing the labeling and packaging of
Alferon N Injection(R) as they are seeking larger production runs for cost
efficiency purposes. We have identified two manufacturers and, on February 8,
2006, we executed a Manufacturing and Safety Agreement with Hyaluron, Inc.
("Hyaluron") of Burlington, Massachusetts, for the formulation, packaging and
labeling of Alferon N Injection(R). Pursuant to the Agreement, we will supply
raw materials in sufficient quantity and provide any pertinent information to
the project.

General and Administrative Expenses

General and Administrative ("G&A") expenses for the year ended December
31, 2004 and 2003 were approximately $6,164,000 and $4,257,000, respectively.
The increase in G&A expenses of $1,907,000 during this period is primarily due
to non-cash charges of $2,000,000 for stock compensation expenses in 2004. These
stock compensation charges consisted of $1,769,000 resulting from warrants
issued to Dr. Carter in 2003 that vested in 2004 and directors' fees paid in
2004 of $231,000. The warrants noted above vested upon the second ISI asset
closing which occurred on March 17, 2004. In addition, investment banking fees
relating to assistance in financing matters increased in 2004 as compared to a
period early by approximately $124,000. These increases were offset by a
decrease in service fees in 2004 of approximately $191,000 as compared to a year
earlier. These services fees related to the acquisition of ISI.

Impairment loss

During the year ended December 31, 2004, we recorded a non-cash charge of
$373,000 with respect to our investment in Chronix. This impairment reduces our
carrying value to reflect a permanent decline in Chronix's market value based on
its then proposed investment offerings.

Other Income/Expense

Interest and other income for the year ended December 31, 2004 and 2003
totaled $49,000 and $80,000, respectively. All funds in excess of our immediate
need are invested in short-term high quality securities.

62
Interest Expense and Financing Costs

Interest expense and financing costs, as restated, were $13,852,000 for
the year ended December 31, 2004 versus $6,821,000 for the same period a year
ago. Non-cash financing costs consist of the amortization of debenture closing
costs, the amortization of Original Issue Discounts and the amortization of
costs associated with beneficial conversion features of our debentures and the
fair value of the warrants relating to the Debentures. These charges are
reflected in the Consolidated Statements of Operations under the caption
"Financing Costs."


Liquidity And Capital Resources

Cash used in operating activities for the year ended December 31, 2005 was
$7,236,000. Cash provided by financing activities for the year ended December
31, 2005 amounted to $8,034,000, substantially from proceeds from the sale of
common stock. As of December 31, 2005, and March 28, 2006 we had approximately
$16,204,000 and $22,400,000 in cash and cash equivalents and short-term
investments, respectively. These funds should be sufficient to meet our
operating cash requirements including debt service for the near term. However,
we may need to raise additional funds through additional equity or debt
financing or from other sources in order to complete the necessary clinical
trials and the regulatory approval processes including the commercializing of
Ampligen(R) products. There can be no assurances that we will raise adequate
funds from these or other sources, which may have a material adverse effect on
our ability to develop our products. Also, we have the ability to curtail
discretionary spending, including some research and development activities, if
required to conserve cash.

Because of our long-term capital requirements, we may seek to access the
public equity market whenever conditions are favorable, even if we do not have
an immediate need for additional capital at that time. Any additional funding
may result in significant dilution and could involve the issuance of securities
with rights, which are senior to those of existing stockholders. We may also
need additional funding earlier than anticipated, and our cash requirements, in
general, may vary materially from those now planned, for reasons including, but
not limited to, changes in our research and development programs, clinical
trials, competitive and technological advances, the regulatory process, and
higher than anticipated expenses and lower than anticipated revenues from
certain of our clinical trials for which cost recovery from participants has
been approved.

March 2003 Debenture

On March 12, 2003, we issued an aggregate of $5,426,000 in principal
amount of 6% Senior Convertible Debentures due January 2005 (the "March 2003
Debentures") and an aggregate of 743,288 warrants to two investors in a private
placement for aggregate gross proceeds of $4,650,000. The March 2003 Debentures
were to mature on January 31, 2005 and bore interest at 6% per annum, payable
quarterly in cash or, subject to satisfaction of certain conditions, common
stock. Any shares of common stock issued to the investors as payment of interest
were valued at 95% of the average closing price of the common stock during the
five consecutive business days ending on the third business day immediately
preceding the applicable interest payment date. Pursuant to the terms and
conditions of the March 2003 Debentures, we pledged all of our assets, other
than our intellectual property, as collateral and were subject to comply with
certain financial and negative covenants, which include but were not limited to
the repayment of principal balances upon achieving certain revenue milestones.
The March 2003 debenture, at issuance, was recorded at a discount of $4,194,520
due to the fair value ascribed to the detachable warrants using the
Black-Scholes Method and the effect of a beneficial conversion feature.

The March 2003 Debentures were convertible at the option of the investors
at any time through January 31, 2005 into shares of our common stock. The
conversion price under the March 2003 Debentures was fixed at $1.46 per share,
subject to adjustment for anti-dilution protection for issuance of common stock
or securities convertible or exchangeable into common stock at a price less than
the conversion price then in effect.

The investors also received Warrants to acquire at any time through March
12, 2008 an aggregate of 743,288 shares of common stock at a price of $1.68 per
share. All of these warrants have been exercised.

On June 25, 2003, we issued to each of the March 2003 Debenture holders
warrants to acquire at any time through June 25, 2008 an aggregate of 1,000,000
shares of common stock at a price of $2.40 per share (the "June 2008 Warrants").
These warrants were issued as incentive for the debenture holders to exercise
prior warrant issuances. This issuance, as restated, resulted in an additional
debt discount to the March 2003 Debentures of $1,320,000 to be amortized over
the remaining life of the debenture or in the event of conversion written off to
financing costs on pro-rata basis. Pursuant to our agreement with the March 2003
Debenture holders, we registered the shares issuable upon exercise of these June
2008 Warrants for public sale.

On May 14, 2004, in consideration for the March 2003 Debenture holders'
exercise of all of the June 2008 Warrants, we issued to the holders warrants
(the "May 2009 Warrants") to purchase an aggregate of 1,300,000 shares of our
common stock. We issued 1,000,000 shares of common stock and received gross
proceeds of $2,400,000 from the exercise of the June 2008 Warrants.

64
The May 2009  Warrants are to acquire at any time  commencing  on November
14, 2004 through April 30, 2009 an aggregate of 1,300,000 shares of common stock
at a price of $4.50 per share. This transaction generated a non-cash charge of
approximately $2,355,000 in financing costs during the second quarter of 2004.
This was written off as the March 2003 Debenture holders had fully converted
their note in 2003. Upon completion of the August 2004 Private Placement (see
below), the exercise price was lowered to $4.008 per share. On May 14, 2005, the
exercise price of these May 2009 Warrants was reset again to the lesser of the
exercise price then in effect or a price equal to the average of the daily price
of the common stock between May 15, 2004 and May 13, 2005. The exercise price
(and the reset price) under the May 2009 Warrants also is subject to adjustments
for anti-dilution protection similar to those in the other Warrants.
Notwithstanding the foregoing, the exercise price as reset or adjusted for
anti-dilution, will in no event be less than $4.008 per share. We recorded an
additional charge to financing costs of $39,000 to account for the reset of the
exercise price of these warrants.

As of December 31, 2003, the investors had converted the total $5,426,000
principal of the March 2003 Debentures into 3,716,438 shares of our common
stock. Financing costs and interest expense incurred for the year ended December
31, 2003, on the March 2003 Debenture amounted to $3,703,166 and $112,000,
respectively. The interest due on this debenture was paid in cash of $17,000
with $94,000 being paid by the issuance of shares of our common stock. The
investor exercised all 743,288 warrants in July 2003 which produced gross
proceeds in the amount of approximately $1,249,000.


July 2003 Debenture

On July 10, 2003, we issued an aggregate of $5,426,000 in principal amount
of 6% Senior Convertible Debentures due July 31, 2005 (the "July 2003
Debentures") and an aggregate of 507,102 Warrants (the "July 2008 Warrants") in
a private placement for aggregate proceeds of $4,650,000. Pursuant to the terms
of the July 2003 Debentures, $1,550,000 of the proceeds from the sale of the
July 2003 Debentures were to have been held back and released to us if, and only
if, we acquired ISI's facility with in a set timeframe. These funds were
released to us in October 2003 although we had not acquired ISI's facility at
that time. The July 2003 Debentures matured on July 31, 2005 and bore interest
at 6% per annum, payable quarterly in cash or, subject to satisfaction of
certain conditions, common stock. Any shares of common stock issued to the
investors as payment of interest were valued at 95% of the average closing price
of the common stock during the five consecutive business days ending on the
third business day immediately preceding the applicable interest payment date.
The July 2003 debenture, at issuance, was recorded at a discount of $3,587,000
due to the fair value ascribed to the warrant using Black-Scholes Method and the
effect of a beneficial conversion feature.

The July 2003 Debentures were convertible at the option of the investors
at any time through July 31, 2005 into shares of our common stock. The
conversion price under the July 2003 Debentures was fixed at $2.14 per share;
however, as part of the subsequent debenture placement closed on October 29,
2003 (see below), the conversion price under the July 2003 Debentures was
lowered to $1.89 per share. The conversion price was subject to adjustment for
anti-dilution protection for issuance of common stock or securities convertible
or exchangeable into common stock at a price less than the conversion price then
in effect. In addition, in the event that we did pay the redemption price at
maturity, the Debenture holders, at their option, may have converted the balance
due at the lower of (a) the conversion price then in effect and (b) 95% of the
lowest closing sale price of our common stock during the three trading days
ending on and including the conversion date. In 2003, we recorded a debt
discount of approximately $741,000 upon the conversion price reset to $1.89 per
share. The additional debt discount is amortized over the remaining life of the
debenture or in the event of a conversion written off to financing costs on a
pro-rata basis.

65
The July 2008  Warrants  received by the  investors,  as amended,  were an
aggregate of 507,102 shares of common stock at a price of $2.46 per share. The
amended Warrants did not result in any additional debt. These Warrants were
exercised in July 2004 which produced gross proceeds in the amount of
$1,247,000.

As of December 31, 2004, the investors had converted the total $5,426,000
principal of the July Debentures into 2,870,900 shares of common stock.

We recorded financing costs for the years ended December 31, 2004 and
2003, with regard to the July 2003 Debentures of $2,516,000 and $1,281,000,
respectively. Interest expense for the year ended December 31, 2003, with regard
to the July 2003 Debentures was $117,000.

October 2003 Debenture

On October 29, 2003, we issued an aggregate of $4,142,357 in principal
amount of 6% Senior Convertible Debentures due October 31, 2005 (the "October
2003 Debentures") and an aggregate of 410,134 Warrants (the "October 2008
Warrants") in a private placement for aggregate gross proceeds of $3,550,000.
Pursuant to the terms of the October 2003 Debentures, $1,550,000 of the proceeds
from the sale of the October 2003 Debentures were held back and were to be
released to us if, and only if, we acquired ISI's facility within 90 days of
January 26, 2004 and provide a mortgage on the facility as further security for
the October 2003 Debentures. In April 2004, we acquired the facility and we
subsequently provided the mortgage of the facility to the Debenture holders and
the above funds were released. The October 2003 Debentures were to mature on
October 31, 2005 and bore interest at 6% per annum, payable quarterly in cash
or, subject to satisfaction of certain conditions, common stock. Any shares of
common stock issued to the investors as payment of interest shall be valued at
95% of the average closing price of the common stock during the five consecutive
business days ending on the third business day immediately preceding the
applicable interest payment date. The October 2003 debenture, at issuance, was
recorded at a discount of $3,177,000 due to the fair value ascribed to the
warrants using Black-Scholes and the effect of the beneficial conversion
feature.

In October 2005, we entered into an amendment agreement with the October
2003 Debenture holders to amend the maturity date from October 31, 2005 to June
30, 2007, and increase the interest rate from 6% to 7% (see "Debenture Agreement
Amendment" below for more details).

Upon completing the sale of the October 2003 Debentures, we received
$3,275,000 in net proceeds consisting of $1,725,000 from the October 2003
Debentures and $1,550,000 that had been withheld from the July 2003 Debentures.
As noted above, pursuant to the terms of the October 2003 Debentures, $1,550,000
of the proceeds from the sale of the October 2003 Debentures had been held back.
However, these proceeds were released to us in April 2004. As required by the
Debentures, we have provided a mortgage on the ISI facility as further security
for the Debentures.

66
The October 2003 Debentures are convertible at the option of the investors
at any time through October 31, 2005 into shares of our common stock. The
conversion price under the October 2003 Debentures is fixed at $2.02 per share,
subject to adjustment for anti-dilution protection for issuance of common stock
or securities convertible or exchangeable into common stock at a price less than
the conversion price then in effect. In addition, in the event that we do not
pay the redemption price at maturity, the Debenture holders, at their option,
may convert the balance due at the lower of (a) the conversion price then in
effect and (b) 95% of the lowest closing sale price of our common stock during
the three trading days ending on and including the conversion date.

The October 2008 Warrants, as amended, received by the investors were to
acquire an aggregate of 410,134 shares of common stock at a price of $2.32 per
share. The amended Warrants resulted in an additional debt discount of
approximately $53,000 in 2004 to be amortized over the remaining life of the
October 2003 debenture or in the event of conversion be written off to financing
costs on a pro-rata basis. These Warrants were exercised in July 2004 which
produced gross proceeds in the amount of approximately $952,000.

As noted above, on July 13, 2004, in consideration for the Debenture
holders' exercise of all of the July 2003 and October 2003 Warrants amounting to
approximately $2,199,000 in gross proceeds, we issued to these holders warrants
(the "June 2009 Warrants") to purchase an aggregate of 1,300,000 shares of
common stock since the July 2003 debenture was fully converted in July 2004. The
issuance of these warrants resulted in an additional debt discount to the
October 2003 Debenture, as restated, of $1,515,000 and a financing charge, as
restated, of $2,128,000. The additional debt discount of $1,515,000 will be
amortized over the remaining life of the debenture.

The June 2009 Warrants are to acquire at any time commencing on January
13, 2005 through June 30, 2009 an aggregate of 1,300,000 shares of common stock
at a price of $3.75 per share. On July 13, 2005, the exercise price of these
June 2009 Warrants was reset to the lesser of the exercise price then in effect
or a price equal to the average of the daily price of the common stock between
July 14, 2004 and July 12, 2005. The exercise price (and the reset price) under
the June 2009 Warrants also is subject to adjustments for anti-dilution
protection similar to those in the other Warrants. Notwithstanding the
foregoing, the exercise price as reset or adjusted for anti-dilution, will in no
event be less than $3.33 per share. Upon completion of the August 2004 Private
Placement (see below), the exercise price was lowered to $3.33 per share. We
agreed to register the shares issuable upon exercise of the June 2009 Warrants
pursuant to substantially the same terms as the registration rights agreements
between us and the holders. Pursuant to this obligation, we have registered the
shares.

We have paid $1,300,000 into the debenture cash collateral account as
required by the terms of the October 2003 Debentures. The amounts paid through
December 31, 2005 have been accounted for as advances receivable and are
reflected as such on the accompanying balance sheet as of December 31, 2005. The
cash collateral account provides partial security for repayment of the
outstanding Debentures in the event of default.

As of December 31, 2005, the investors had converted $2,071,178 principal
amount of the October 2003 Debenture into 1,025,336 shares of Common Stock. The
remaining balance of $2,071,178 is convertible into 1,025,336 shares of common
stock.

67
We recorded  financing  costs for the years ended December 31, 2005,  2004
and 2003, with regard to the October 2003 Debentures of $1,142,000, $1,212,000
and $274,000, respectively. Interest expense for the years ended December 31,
2005, 2004 and 2003, with regard to the October 2003 Debentures was $129,000,
$118,000 and $24,000, respectively.

January 2004 Debenture

On January 26, 2004, we issued an aggregate of $4,000,000 in principal
amount of 6% Senior Convertible Debentures due January 31, 2006 (the "January
2004 Debentures"), an aggregate of 790,514 warrants (the "July 2009 Warrants")
and 158,103 shares of common stock, and Additional Investment Rights (to
purchase up to an additional $2,000,000 principal amount of January 2004
Debentures commencing in six months) in a private placement for aggregate net
proceeds of $3,695,000. The January 2004 Debentures mature on January 31, 2006
and bear interest at 6% per annum, payable quarterly in cash or, subject to
satisfaction of certain conditions, common stock. Any shares of common stock
issued to the investors as payment of interest shall be valued at 95% of the
average closing price of the common stock during the five consecutive business
days ending on the third business day immediately preceding the applicable
interest payment date. Pursuant to the terms of the January 2004 debentures,
commencing July 26, 2004, we began to repay the then outstanding principal
amount under the Debentures in monthly installments amortized over 18 months in
cash or, at our option, in shares of common stock. Any shares of common stock
issued to the investors as installment payments shall be valued at 95% of the
average closing price of the common stock during the 10-day trading period
commencing on and including the eleventh trading day immediately preceding the
date that the installment is due. The January 2004 debenture, at issuance, was
recorded at a discount of $2,463,000 due to the fair value of the warrants using
Black-Scholes and the effect of the beneficial conversion feature.

The January 2004 Debentures are convertible at the option of the investors
at any time through January 31, 2006 into shares of our common stock. The
conversion price under the January 2004 Debentures was fixed at $2.53 per share,
subject to adjustment for anti-dilution protection for issuance of common stock
or securities convertible or exchangeable into common stock at a price less than
the conversion price then in effect. In addition, in the event that we do not
pay the redemption price at maturity, the Debenture holders, at their option,
may convert the balance due at the lower of (a) the conversion price then in
effect and (b) 95% of the lowest closing sale price of our common stock during
the three trading days ending on and including the conversion date. Upon
completion of the August 2004 Private Placement, the conversion price was
lowered to $2.08 per share. We recorded an additional debt discount as restated
(see Note 2), of approximately $915,000 due to this conversion price reset.

In October 2005, we entered into an amendment agreement with the January
2004 Debenture holders to amend the maturity date from October 31, 2005 to June
30, 2007, and increase the interest rate from 6% to 7% (see "Debenture Agreement
Amendment" below for more details).

There are two classes of July 2009 Warrants received by the Investors:
Class A and Class B. The Class A warrants are to acquire any time from July 26,
2004 through July 26, 2009 an aggregate of up to 395,257 shares of common stock
at a price of $3.29 per share. The Class B warrants are to acquire any time from
July 26, 2004 through July 26, 2009 an aggregate of up to 395,257 shares of
common stock at a price of $5.06 per share. On January 27, 2005, the exercise
price of these July 2009 Class A and Class B Warrants were reset to the lesser
of their respective exercise price then in effect or a price equal to the
average of the daily price of the common stock between January 27, 2004 and
January 26, 2005. The exercise price (and the reset price) under the July 2009
Warrants also is subject to similar adjustments for anti-dilution protection.
Notwithstanding the foregoing, the exercise prices as reset or adjusted for
anti-dilution, will in no event be less than $2.58 per share. Upon completion of
the August 2004 Private Placement (see Note 9), the exercise price was lowered
to $2.58 per share. In 2004, as restated, and 2005, we recorded an additional
charge to financing costs of $108,000 and $228,000 respectively, to account for
the reset of the exercise price of the July 2009 warrants to $2.58 per share.

68
As of December 31, 2005,  the investors had made  installment  payments of
$1,888,888 and converted $746,510 principal amount of the January 2004
Debentures into 1,094,149 and 347,000 shares of common stock, respectively. The
remaining principal on these debentures was $1,364,602 as of December 31, 2005.

We recorded financing costs for the years ended December 31, 2005 and 2004
with regard to the January 2004 Debentures of $1,486,000 and $1,750,000,
respectively. Interest expense for the years ended December 31, 2005 and 2004,
with regard to the January 2004 Debentures was $145,000 and $207,000,
respectively.


July 2004 Debentures

Pursuant to the Additional Investment Rights issued in connection with the
January 2004 and July 2004 debentures, we issued to the investors an additional
$2,000,000 principal amount of January 2004 Debentures (the July 2004
Debentures"). The July 2004 Debentures are identical to the January 2004
Debentures except that the conversion price is $2.58. The investors exercised
the Additional Investment Rights on July 13, 2004 and we received net proceeds
of $1,860,000. Upon completion of the August 2004 Private Placement , the
conversion price was lowered to $2.08 per share. The July 2004 debentures, at
issuance, were recorded at a discount of $628,000 due to the embedded conversion
feature and the fair value of the warrants utilizing the Black-Scholes Method.
We recorded a reduction in debt discount of approximately $628,000 upon the
conversion price reset to $2.08 per share, which is being amortized over the
remaining life of the debenture.

In October 2005, we entered into an amendment agreement with the July 2004
Debenture holders to amend the maturity date from October 31, 2005 to June 30,
2007, and increase the interest rate from 6% to 7% (see "Debenture Agreement
Amendment" below for more details).

As of December 31, 2005, we made installment payments of $500,000
resulting in the issuance of 331,669 shares of our common stock. The Debenture
holders had not converted any portion of this debenture as of December 31, 2005.

We recorded financing costs for the years ended December 31, 2005 and 2004
with regard to the July 2004 Debentures of $808,000 and $297,000, respectively.
Interest expense for the years ended December 31, 2005 and 2004, with regard to
the January 2004 Debentures was $113,000 and $61,000, respectively.

69
Debenture Agreement Amendment

On October 6, 2005, we entered into a material definitive agreement with
the October 2003, January 2004 and July 2004 debenture holders to 1) amend the
remaining outstanding debentures that were to mature on October 31, 2005 (as
amended, the "Series A Debenture") and the two traunches of outstanding
debentures due to mature on January 31, 2006 (as amended, respectively, the
"Series B and Series C Debentures"), to a maturity date of June 30, 2007, 2) to
increase the interest rate from 6% per annum to 7% per annum. In consideration
for extending the maturity date of the outstanding debentures, we issued an
aggregate of 225,000 Warrants (the "October 2009 Warrants") to the debenture
holders to acquire common stock at a price of $2.50 per share at any time from
October 31, 2005 through October 31, 2009. The October 2009 Warrants contain
provisions for adjustment of the exercised price in the event of certain
anti-dilution events. We agreed to register 135% of the shares issuable as
interest shares that might result due to the amendments to the Debentures and
issuable upon exercise of the October 2009 Warrants.

The above transaction and amendment to the existing terms of the
above-mentioned debentures would fall under EITF 96-19, "Debtor's Accounting for
a Modification or Exchange of Debt Instruments". This EITF discussed and reached
a consensus that a substantial modification of terms should be accounted for,
and reported in the same manner as, an extinguishment. Any modification of a
debt instrument between a debtor and creditor in a non-troubled debt situation
is deemed to be a substantial modification in the event the present value of the
cash flows under the new terms of the new debt instrument is at least 10 percent
different from the present value of the remaining cash flows under the terms of
the original instrument. In the event the cash flow effect of the present value
basis is less than 10 percent, the debt instruments are not considered to be
substantially different. The discount rate to be used to calculate the present
value of the cash flows is the effective interest rate of the original debt
instrument. Accordingly, we have treated the change in terms to the original
debentures as non-substantial in nature and have not accounted for such
modification as an extinguishment of debt, but rather a debt modification. In
addition, the 225,000 warrants issued to the debenture holders as consideration
for extending the maturity date were valued using the Black-Scholes method was
$556,000 and recorded as additional debt discount on the July 2004 Debenture.
The discount will be amortized as interest expense over the new term of the debt
instrument. Any costs incurred by third parties were expensed as incurred.

Registration Rights Agreements

We entered into Registration Rights Agreements with the investors in
connection with the issuance of (i) the above Debentures; (ii) the June 2008,
July 2008, October 2008, July 2009, and May 2009 Warrants (collectively, the
"Warrants"); and (iii) the shares issued in January 2004. Pursuant to the
Registration Rights Agreements we have registered on behalf of the investors the
shares issued to them in January 2004 and 135% of the shares issuable upon
conversion of the Debentures and upon exercise of all of the Warrants. If,
subject to certain exceptions, sales of all shares so registered cannot be made
pursuant to the registration statements, then we will be required to pay to the
investors their pro rata share of $.00067 times the outstanding principal amount
of the relevant Debentures for each day the above condition exists.

Investment Banking Fees

By agreement with Cardinal Securities, LLC, for general financial advisory
services and in conjunction with the private debenture placements in July and
October 2003 and in January and July 2004, we paid Cardinal Securities, LLC an
investment banking fee equal to 7% of the investments made by the Debenture
holders and issued to Cardinal the following warrants to purchase common stock:
(i) 112,500 exercisable at $2.57 per share; (ii) 87,500 exercisable at $2.42 per
share; and (iii) 100,000 exercisable at $3.04 per share. The $2.57 warrants
expire on July 10, 2008, the $2.42 warrants expire on October 29, 2008 and the
$3.04 warrants expire on January 5, 2009. With regard to the exercise of the
June 2008 Warrants and issuance of the May 2009 Warrants, Cardinal received an
investment banking fee of 7%, half in cash and half in shares. With regard to
the exercise of the Additional Investment Rights, the July 2008 and October 2008
Warrants and issuance of the July 2009 Warrants, Cardinal received an investment
banking fee of 7%, $146,980 in cash and 22,703 in shares as well as 50,000
warrants exercisable at $4.07 expiring on July 12, 2009. By agreement with
Cardinal, we have registered all of the foregoing shares and shares issuable
upon exercise of the above mentioned warrants for public resale. As a result of
all of the transactions discussed above, we recorded $715,000, as restated as
deferred financing costs on the balance sheet.

Section 713 of the American Stock Exchange Company Guide

As discussed below, Section 713 of the American Stock Exchange ("AMEX")
Company Guide provides that we must obtain stockholder approval before issuance,
at a price per share below market value, of common stock, or securities
convertible into common stock, equal to 20% or more of our outstanding common
stock (the "Exchange Cap"). The Debentures and Warrants have provisions that
require us to pay cash in lieu of issuing shares upon conversion of the
Debentures or exercise of the Warrants if we are prevented from issuing such
shares because of the Exchange Cap. In May 2004, the Debenture holders agreed to
amend the provisions of these Debentures and Warrants to limit the maximum
amount of funds that the holders could receive in lieu of shares upon conversion
of the Debentures and/or exercise of the Warrants in the event that the Exchange
Cap was reached to 119.9% of the conversion price of the relevant Debentures and
19.9% of the relevant Warrant exercise price. See below for the accounting
effect on this matter.

Taken separately, the March, July, October and January 2004 debenture
transactions do not trigger Section 713. However, the AMEX took the position
that these transactions should be aggregated and, as such, stockholder approval
was required for the issuance of common stock for a portion of the potential
exercise of the warrants and conversion of the Debentures in connection with the
January 2004 Debentures. The amount of potential shares that we could exceed the
Exchange Cap amounted to approximately 1,299,000. In accordance with EITF 00-19,
Accounting For Derivative Financial Instruments Indexed to and Potentially
Settled in a Company's Own Stock, we recorded on January 26, 2004, a redemption
obligation of approximately $1,244,000. This liability represented the fair
market value of the warrants and beneficial conversion feature related to the
1,299,000 shares.

In addition, in accordance with EITF 00-19, we revalued this redemption
obligation associated with the beneficial conversion feature and warrants as of
March 31, 2004. We recorded an additional redemption obligation and finance
charge of $947,000 as a result of this revaluation. Upon stockholder approval,
our redemption obligation was recorded as additional paid in capital as of the
date approval was received.

The requisite stockholder approval was obtained at our Annual Meeting of
Stockholders on June 23, 2004. In accordance with EITF 00-19, we revalued this
redemption obligation associated with the beneficial conversion feature and
warrants as of June 23, 2004. We recorded a reduction in the value of the
redemption obligation and financing charge of $260,000 as a result of this
revaluation. In addition, upon receiving the requisite stockholder approval,
this redemption obligation was reclassified as additional paid in capital as of
the date the approval was received or June 23, 2004.

Accounting Guidance

The March, July, October, January 2004 and July 2004 issuances of 6%
Senior Convertible Debentures in the principal amounts of $5,426,000,
$5,426,000, $4,142,357 and $4,000,000 and $2,000,000 respectively and related
embedded conversion features and warrants issuances were accounted for in
accordance with EITF 98-5: Accounting for convertible securities with beneficial
conversion features or contingency adjustable conversion and with EITF No.
00-27: Application of issue No. 98-5 to Certain convertible instruments. We
determined the fair values to be ascribed to detachable warrants issued with the
convertible debentures utilizing the Black-Scholes method. In addition, upon the
debenture holders conversion of any debt principle, we would write off the
pro-rata portion of the debt discount applicable to the conversion.

Collateral and Financial Covenants

Pursuant to the terms and conditions of all of the outstanding Debentures,
we have pledged all of our assets, other than our intellectual property, as
collateral, and we are subject to comply with certain financial covenants. As of
December 31, 2005, we was in compliance with debt covenants contained within our
debenture agreements.

In connection with the Debenture agreements, we has outstanding letters of
credit of $1 million as additional collateral.


Equity Financings

On August 5, 2004, we closed a private placement with select institutional
investors ("August 2004 Private Placement") of approximately 3,617,300 shares of
Common Stock and warrants to purchase an aggregate of up to approximately
1,085,200 shares of Common Stock. Jefferies & Company, Inc. acted as Placement
Agent for which it received a fee and warrants to purchase Common Stock. We
raised approximately $6,984,000 net proceeds from this private offering.

The Warrant issued to each purchaser is exercisable for up to 30% of the
number of shares of Common Stock purchased by such Purchaser, at an exercise
price equal to $2.86 per share. Each Warrant has a term of five years and is
fully exercisable from the date of issuance. Pursuant to the Registration Rights
Agreement, made and entered into as of August 5, 2004 (the "Rights Agreement"),
we registered the resales of the shares issued to the Purchasers and shares
issuable upon the exercise of the Warrants.

By agreement with Cardinal Securities, LLC, for general financial advisory
services and in conjunction with the August 2004 Private Placement with select
institutional investors, we paid Cardinal Securities, LLC an investment banking
fee of $140,000. We paid Cardinal one-half of the fee in cash with the remainder
being paid with the issuance of 50,000 warrants to purchase common stock
exercisable at $2.50 per share expiring on March 31, 2010 and 46,667 shares of
common stock. By agreement with Cardinal, we registered all of the foregoing
shares and shares issuable upon exercise of the above mentioned warrants for
public resale.

72
Closing of the August 2004 Private  Placement  triggered the anti-dilution
provisions of the January 2004 Debentures and the July 2004 Debentures and the
July 2009 Warrants and the June 2009 Warrants. The conversion price adjustment
for the Debentures noted above resulted in an adjustment of $1,320,000 in the
third quarter 2004 to the Debenture discount and additional paid-in-capital
using the Black-Scholes Method. Any adjustment to the Debenture discount will be
amortized over the remaining life of the Debentures.

On July 8, 2005, we entered into a common stock purchase agreement with
Fusion Capital Fund II, LLC ("Fusion Capital"), pursuant to which Fusion Capital
agreed, under certain conditions, to purchase on each trading day $40,000 of our
common stock, unless our stock price equals or exceeds $2.00 in which case the
daily amount may be increased under certain conditions as the price of the
common stock increases, up to an aggregate of $20.0 million over approximately a
25 month period, subject to earlier termination at our discretion. In our
discretion, we may elect to sell less common stock to Fusion Capital than the
daily amount and we may increase the daily amount as the market price of our
stock increases. The purchase price of the shares of common stock will be equal
to a price based upon the future market price of the common stock without any
fixed discount to the market price. Fusion Capital does not have the right or
the obligation to purchase shares of our common stock in the event that the
price of the common stock is less than $1.00. Since we initially registered
10,000,000 shares purchasable by Fusion Capital pursuant to the common stock
purchase agreement, the selling price of our common stock to Fusion Capital will
have to average at least $2.00 per share for us to receive the maximum proceeds
of $20.0 million without registering additional shares of common stock. As of
March 24, 2006, we need an average selling price of $0.99 per share for the
remainder of the agreement to realize the $20,000,000 in proceeds. The closing
price of our stock was $3.78 on March 24, 2006.

Pursuant to our agreement with Fusion Capital, we registered for public
sale by Fusion Capital up to 10,795,597 shares of our common stock. However, in
the event that we decide to issue more than 10,113,278, i.e. greater than 19.99%
of the outstanding shares of common stock as of the date of the agreement, we
would first seek stockholder approval in order to be in compliance with American
Stock Exchange rules. As of March 24, 2006, Fusion Capital has purchased
8,211,508 shares amounting to $18,230,011 in our receipt of gross proceeds.

In connection with entering into the above agreement with Fusion Capital,
in July 2005, we issued to Fusion Capital 402,798 shares of common stock.
392,798 of these shares represented 50% of the commitment fee due Fusion Capital
with the remaining 10,000 shares issued as reimbursement for expenses. An
additional 392,799 shares, representing the remaining balance of the commitment,
are issuable in conjunction with daily purchases of common stock by Fusion
Capital. These additional commitment shares will be issued in an amount equal to
the product of (x) 392,799 and (y) the Purchase Amount Fraction. The "Purchase
Amount Fraction" means a fraction, the numerator of which is the purchase price
at which the shares are being purchased by Fusion Capital and the denominator of
which is $20,000,000. As of March 24, 2006, Fusion Capital was issued 358,036
shares towards this remaining commitment fee.

73
ASSET ACQUISITIONS

In March 2003, we acquired from ISI, ISI's inventory of Alferon N
Injection(R) and a limited license for the production, manufacture, use,
marketing and sale of this product. As partial consideration, we issued 487,028
shares of our common stock to ISI. Pursuant to our agreements with ISI, we
registered these shares for public sale and ISI reported that it sold all of
these shares. We also agreed to pay ISI 6% of the net sales of Alferon N
Injection(R).

In March 2003, we also entered into an agreement to purchase from ISI all
of its rights to the product and other assets related to the product including,
but not limited to, real estate and machinery. For these assets, we issued to
ISI an additional 487,028 shares and issued 314,465 shares and 267,296 shares,
respectively to the American National Red Cross and GP Strategies Corporation,
two creditors of ISI. We guaranteed the market value of all but 62,500 of these
shares to be $1.59 per share on the termination date. ISI, GP Strategies and the
American National Red Cross reported that they sold all of their shares.

Pursuant to the acquisition agreement, we satisfied other liabilities of
ISI which were past due and secured by a lien on ISI's real estate and pays ISI
a 6% royalty on the net sales of products containing natural alpha interferon.

On May 30, 2003, we issued the shares to GP Strategies and the American
National Red Cross. Pursuant to our agreements with ISI and these two creditors,
we registered the foregoing shares for public sale. As a result at December 31,
2003 the guaranteed value of these shares ($491,000), which had not been sold by
these two creditors, were reclassified to redeemable common stock. At December
31, 2004, all shares had been sold by these two creditors and the redeemable
common stock was reclassified to equity.

On November 6, 2003, we acquired and subsequently paid, the outstanding
ISI property tax lien certificates in the aggregate amount of $457,000 from
certain investors. These tax liens were issued for property taxes and utilities
due for 2000, 2001 and 2002.

In March 2004, we issued 487,028 shares to ISI to complete the acquisition
of the balance of ISI's rights to market its product as well as its production
facility in New Brunswick, New Jersey. ISI has sold all of its shares. The
aggregated cost of the land and buildings was approximately $3,316,000. The cost
of the land and buildings was allocated as follows:

Land $ 423,000

Buildings 2,893,000
---------

Total cost $ 3,316,000

We accounted for these transactions as a Business Combination under SFAS
No. 141 Accounting for Business Combinations.

New Accounting Pronouncements

On December 2004, the FASB issued Statement of Financial Accounting
Standards No. 123 (Revised 2004), "Share-Based Payment" ("SFAS 123R"). On April
14, 2005, the Securities and Exchange Commission issued an amendment to Rule
4-01 of Regulation S-X that allows companies to implement SFAS 123R at the
beginning of their next fiscal year, instead of the next reporting period that
begins after June 15, 2005 as originally required. Accordingly, we will adopt
SFAS 123R effective January 1, 2006 using the "modified prospective" method in
which compensation cost is recognized beginning with the effective date base on
(a) the requirements of SFAS 123R for all share-based payments granted after the
effective date and (b) the requirements of SFAS 123 for all awards granted to
employees prior to the effective date of SFAS 123R that remain unvested on the
effective date. In addition, we expect to continue to utilize the Black-Scholes
option-pricing model, which is an acceptable option valuation model in
accordance with SFAS 123R, to estimate the value of stock options granted to
employees.

Beyond those restricted stock and stock option awards previously granted,
we cannot predict with certainty the impact of SFAS 123R on its future
consolidated financial statements as the type and amount of such awards are
determined on an annual basis and encompass a potentially wide range depending
upon the compensation decisions made by the Human Resources Committee of our
Board of Directors. SFAS 123R also requires the benefits of tax deductions in
excess of compensation cost recognized in the financial statements to be
reported as a financing cash flow, rather than an operating cash flow as
currently required under Statement of Financial Accounting Standards No. 95,
"Statement of Cash Flows" ("SFAS 95"). This requirement, to the extent it
exists, will decrease net operating cash flows and increase net financing cash
flows in periods subsequent to adoption. We cannot estimate what those amounts
will be in the future because they depend on, among other things, when employees
exercise stock options.

On March 29, 2005, the SEC issued Staff Accounting Bulletin No. 107 ("SAB
107") which expresses the view of the SEC Staff regarding the interaction of
SFAS 123R and certain SEC rules and regulations and provides the staff's views
regarding the valuation of share-based payment arrangements. We believe that the
views provided in SAB 107 are consistent with the approach taken in the
valuation and accounting associated with share-based compensation issued in
prior periods as well as those issued during 2005.

75
In June 2005, the FASB's  Emerging  Issues Task Force ("EITF") issued EITF
Issue No. 05-02 "The Meaning of "Conventional Convertible Debt Instrument" in
EITF Issue 00-19 "Accounting for Derivative Financial Instruments Indexed to,
and Potentially Settled in, A Company's Own Stock", which retains the exception
in paragraph 4 of EITF Issue No. 00-19 for conventional debt instruments. Those
instruments in which the holder has an option to convert the instrument into a
fixed number of shares (or a corresponding amount of cash at the issuer's
discretion) and its ability to exercise the option is based on either (a) the
passage of time or (b) a contingent event, should be considered "conventional"
for purposes of applying that exception. The consensus should be applied on a
prospective basis for new or modified instruments starting from the third
quarter of 2005. The adoption of EITF No. 05-02 is not expected to have a
material effect on the Company's consolidated financial statements or results of
operations.

When there is a modification of a convertible debt instrument, the change
in the fair value of an embedded conversion option should be included in the
analysis of determining whether a debt extinguishment has occurred. The change
in the fair value of the embedded conversion option is calculated as the
difference between the fair value of the conversion option immediately prior to
and after the modification. Also, when a modification of a convertible debt
instrument occurs, the change in the fair value of the embedded conversion prior
should be recognized as a discount (or premium) with a corresponding increase
(or decrease) in additional paid-in capital. Lastly, a beneficial feature should
not be recognized or reassessed upon modification of a convertible debt
instrument. The adoption of EITF No. 05-02 is not expected to have a material
effect on the Company's consolidated financial statements or results of
operations.

In November 2005, FASB issued FSP FAS 115-1 and FAS 124-1, "The Meaning of
Other-Than-Temporary Impairment and Its Application to Certain Investments"
("FSP FAS 115-1"), which provides guidance on determining when investments in
certain debt and equity securities are considered impaired, whether an
impairment is other-than-temporary, and on measuring such impairment loss. FSP
FAS 115-1 also includes accounting considerations subsequent to the recognition
of an other-than-temporary impairment and requires certain disclosures about
unrealized losses that have not been recognized as other-than-temporary
impairments. FSP FAS 115-1 is required to be applied to reporting periods
beginning after December 15, 2005. We are required to adopt FSP FAS 115-1 in the
first quarter of 2006. We do not expect the adoption of this statement to have a
material impact on our consolidated results of operations or financial
condition.

In November 2004, the FASB issued SFAS No. 151, "Inventory Costs - An
amendment of ARB No. 43, Chapter 4" ("SFAS No. 151"). SFAS No. 151 amends the
guidance in Accounting Research Bulletin No. 43, Chapter 4, "Inventory Pricing,"
to clarify the accounting for abnormal amounts of idle facility expense,
freight, handling costs, and wasted material (spoilage). Additionally, SFAS No.
151 requires that the allocation of fixed production overheads to the cost of
conversion be based on the normal capacity of the production facilities. SFAS
No. 151 is required to be adopted in the first quarter of 2006. We have
determined that the adoption of SFAS No. 151 will not have a material impact on
the consolidated financial statements.

76
In  December  2004,  the FASB issued  Statement  of  Financial  Accounting
Standards No. 153 (SFAS 153"), "Exchanges of Non-monetary Assets-an amendment of
APB Opinion No. 29." SFAS 152 addresses the measurement of exchanges of
non-monetary assets. It eliminates the exception from fair value measurement for
non-monetary exchanges of similar productive assets in paragraph 21(b) of APB
Opinion No. 29 "Accounting for Non-monetary Transactions" and replaces it with
an exception for exchanges that do not have commercial substance. A non-monetary
exchange has commercial substance if the future cash flows of the entity are
expected to change significantly as a result of the exchange. As required by
SFAS 153, we adopted this new accounting standard effective July 1, 2005. The
adoption of SFAS 153 did not have a material impact on our financial statements.

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error
Corrections. SFAS No. 154 establishes retrospective application as the required
method for reporting a change in accounting principle in the absence of explicit
transition requirements specific to the newly adopted accounting principle. SFAS
No. 154 also provides guidance for determining whether retrospective application
is impractical. SFAS No. 154 is effective for accounting changes and corrections
of errors made in fiscal years beginning after December 15, 2005. We do not
expect that the adoption of SFAS No. 154 will have a material impact on its
results of operations or financial position.

Disclosure About Off-Balance Sheet Arrangements

Prior to our annual meeting of stockholders in September 2003, we had a
limited number of shares of Common Stock authorized but not issued or reserved
for issuance upon conversion or exercise of outstanding convertible and
exercisable securities such as debentures, options and warrants. Prior to the
meeting, to permit consummation of the sale of the July 2003 Debentures and the
related warrants, Dr. Carter agreed that he would not exercise his warrants or
options unless and until our stockholders approve an increase in our authorized
shares of common stock. For Dr. Carter's waiver of his right to exercise certain
options and warrants prior to approval of the increase in our authorized shares,
we have agreed to compensate Dr. Carter and issued Dr. Carter 1,450,000 warrants
to purchase common stock at $2.20 per share in 2003 that vested in the first
quarter 2004 upon the second ISI asset closing.

In connection with the Debenture agreements, we have outstanding letters
of credit of $1,000,000 as additional collateral.

Critical Accounting Policies

Financial Reporting Release No. 60 requires all companies to include a
discussion of critical accounting policies or methods used in the preparation of
financial statements. Our significant accounting policies are described in the
Notes to the Consolidated Financial Statements. The significant accounting
policies that we believe are most critical to aid in fully understanding our
reported financial results are the following:

Revenue

Revenue from the sale of Ampligen(R) under cost recovery clinical
treatment protocols approved by the FDA is recognized when the treatment is
provided to the patient.

Revenues from the sale of product are recognized when the product is
shipped, as title is transferred to the customer. We have no other obligation
associated with our products once shipment has occurred.

77
Short-term Investments

Investments with original maturities of more than three months and less
than 12 months and marketable equity securities are considered available for
sale. The investments classifiedas available for sale include debt securities
and equity securities carried at estimated fair value. The unrealized gains and
losses are recorded as a component of shareholders' equity. Patents and
Trademarks

Patents and Trademarks

Patents and trademarks are stated at cost (primarily legal fees) and are
amortized using the straight-line method over the estimated useful life of 17
years We review our patents and trademark rights periodically to determine
whether they have continuing value. Such review includes an analysis of the
patent and trademark's ultimate revenue and profitability potential on an
undiscounted cash basis to support the realizability of our respective
capitalized cost. In addition, management's review addresses whether each patent
continues to fit into our strategic business plans.

Convertible Securities with Beneficial Conversion Features

The October, January 2004 and July 2004 Debenture issuances and related
embedded conversion features and warrants issuances were accounted for in
accordance with EITF 98-5: Accounting for convertible securities with beneficial
conversion features or contingency adjustable conversion and with EITF No.
00-27: Application of issue No. 98-5 to certain convertible instruments. We
determined the fair values to be ascribed to detachable warrants issued with the
convertible debentures utilizing the Black-Scholes method.

Concentration of Credit Risk

Our policy is to limit the amount of credit exposure to any one financial
institution and place investments with financial institutions evaluated as being
credit worthy, or in short-term money markets, which are exposed to minimal
interest rate and credit risks. At times, we have bank deposits and overnight
repurchase agreements that exceed federally insured limits.

Concentration of credit risk, with respect to receivables, is limited
through our credit evaluation process. We do not require collateral on our
receivables. Our receivables consist principally of amounts due from wholesale
drug companies as of December 31, 2005.

Please see Note 3 within the Consolidated Financial Statements for a
summary of our significant accounting policies.

Item 7A. Quantitative And Qualitative Disclosures About Market Risk

We had approximately $16,204,000 in cash and cash equivalents and
short-term investments at December 31, 2005. To the extent that our cash and
cash equivalents exceed our near term funding needs, we invest the excess cash
in three to six month high quality interest bearing financial instruments. We
employ established conservative policies and procedures to manage any risks with
respect to investment exposure.

We have not entered into, and do not expect to enter into, financial
instruments for trading or hedging purposes.

ITEM 8. Financial Statements and Supplementary Data.

The consolidated balance sheets as of December 31, 2004 and 2005, and our

concerning the determination of his annual bonus. Dr. Carter is also entitled to
an incentive bonus of 0.5% of the gross proceeds received by us from any joint
venture or corporate partnering arrangement. Dr. Carter's agreement also
provides that he be paid a base salary and benefits through the last day of the
then term of the agreement if he is terminated without "cause", as that term is
defined in agreement. In addition, should Dr. Carter terminate the agreement or
the agreement be terminated due to his death or disability, the agreement
provides that Dr Carter be paid a base salary and benefits through the last day
of the month in which the termination occurred and for an additional twelve
month period. Pursuant to his original agreement, Dr. Carter was granted options
to purchase 73,728 (post split) shares in 1991. The exercise period of these
options is extended through December 31, 2010 and, should Dr. Carter's
employment agreement be extended beyond that date, the option exercise period is
further extended to the last day of the extended employment period.

The amended and restated engagement agreement, retroactive to January 1,
2005, provides for our engagement of Dr. Carter as a consultant related to
patent development, as one of our directors and as chairman of the Executive
Committee of our board of directors until December 31, 2010 unless sooner
terminated for cause or disability. The agreement automatically renews for
successive one year periods after the initial termination date or any renewal
period. Dr. Carter has the right to terminate the agreement on 30 days' prior
written notice. The initial base fee as of January 1, 2004 is $207,777, subject
to annual adjustments equal to the percentage increase or decrease of annual
dollar value of directors' fees provided to our directors during the prior year.
The annual fee is further subject to adjustment based on the average increase or
decrease in the Consumer Price Index for the prior year. In addition, Dr. Carter
could receive an annual performance bonus of up to 25% of his base fee, at the
sole direction of the Compensation Committee of the board of directors, based on
his performance. Dr. Carter will not participate in any discussions concerning
the determination of this annual bonus. Dr. Carter's agreement also provides
that he be paid his base fee through the last day of the then term of the
agreement if he is terminated without "cause", as that term is defined in the
agreement. In addition, should Dr. Carter terminate the agreement or the
agreement be terminated due to his death or disability, the agreement provides
that Dr. Carter be paid fees due him through the last day of the month in which
the termination occurred and for an additional twelve month period.

On February 14, 2005 we entered  into an agreement  with The Sage Group of
Branchburg, New Jersey for R. Douglas Hulse, an Executive Director of The Sage
Group, to serve as President and Chief Operating Officer of our company. In
addition, other Sage Group principals and Senior Directors will be made
available to assist as needed. The engagement is expected to continue for a
period of 18 months; however, it is terminable on 30 days written notice by
either party after 12 months. Compensation for the services include a ten year
warrant to purchase 250,000 shares of our common stock at an exercise price of
$1.55. These warrants were issued to Sage Healthcare Advisors, LLC and are to
vest at the rate of 12,500 per month of the engagement with 25,000 vesting upon
completion of the eighteenth month. Vesting accelerates in the event of a merger
or a purchase of a majority of our assets or equity. We valued these warrants at
$213,000 utilizing the Black-Scholes Method. As of December 31, 2005, the
213,000 was expensed to stock compensation expense. The Sage Group also is to
receive a monthly retainer of $10,000 for the period of the engagement. In
addition, for each calendar year (or part thereof) during which the agreement is
in effect, The Sage Group will be entitled to an incentive bonus in an amount
equal to 0.5% of the gross proceeds received by us during such year from any
joint ventures or corporate partnering arrangements. After termination of the
agreement, The Sage Group will only be entitled to receive the incentive bonus
based upon gross proceeds received by us during the two year period commencing
on the termination of the agreement with respect to any joint ventures or
corporate partnering arrangements entered into by us during the term of the
agreement. Mr. Hulse will devote approximately two to two and one half days per
week to our business.

We entered into an engagement agreement, retroactive to January 1, 2005,
with Ransom W. Etheridge which provides for Mr. Etheridge's engagement as our
General Counsel until December 31, 2009 unless sooner terminated for cause or
disability. The agreement automatically renews for successive one year periods
after the initial termination date unless we or Mr. Etheridge give written
notice otherwise at least ninety days prior to the termination date or any
renewal period. Mr. Etheridge has the right to terminate the agreement on 30
days' prior written notice. The initial annual fee for services is $96,000 and
is annually subject to adjustment based on the average increase or decrease in
the Consumer Price Index for the prior year. Mr. Etheridge's agreement also
provides that he be paid all fees through the last day of then current term of
the agreement if he is terminated without "cause" as that term is defined in the
agreement. In addition, should Mr. Etheridge terminate the agreement or the
agreement be terminated due to his death or disability, the agreement provides
that Mr. Etheridge be paid the fees due him through the last day of the month in
which the termination occurred and for an additional twelve month period. Mr.
Etheridge will devote approximately 85% of his business time to our business.

90
We entered into an amended and restated engagement agreement,  retroactive
to January 1, 2005, with Robert E. Peterson which provides for Mr. Peterson's
engagement as our Chief Financial Officer until December 31, 2010 unless sooner
terminated for cause or disability. Mr. Peterson has the right to terminate the
agreement on 30 days' prior written notice. The initial annual fee for services
is $202,680 and is annually subject to increases based on the average increase
in the cost of inflation index for the prior year. Mr. Peterson shall receive an
annual bonus in each year that our Chief Executive Officer is granted a bonus.
The bonus shall equal a percentage of Mr. Peterson's base annual compensation
comparable to the percentage bonus received by the Chief Executive Officer. In
addition, Mr. Peterson shall receive bonus compensation upon Federal Drug
Administration approval of commercial application of Ampligen(R). Mr. Peterson's
agreement also provides that he be paid all fees through the last day of then
current term of the agreement if he is terminated without "cause" as that term
is defined in the agreement. In addition, should Mr. Peterson terminate the
agreement or the agreement be terminated due to his death or disability, the
agreement provides that Mr. Peterson be paid the fees due him through the last
day of the month in which the termination occurred and for an additional twelve
month period. Mr. Peterson will devote approximately 85% of his business time to
our business.

On March 11, 2005 the Board of Directors, deeming it essential to the best
interests of our shareholders to foster the continuous engagement of key
management personnel and recognizing that, as is the case with many publicly
held corporations, a change of control might occur and that such possibility,
and the uncertainty and questions which it might raise among management, might
result in the departure or distraction of management personnel to the detriment
of our company and our shareholders, determined to reinforce and encourage the
continued attention and dedication of members of our management to their
engagement without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change in control of our company
and entered into identical agreements regarding change in control with William
A. Carter, our Chief Executive Officer and Chief Scientific Officer, Robert E.
Peterson, our Chief Financial Officer and Ransom W. Etheridge, our General
Counsel. Each of the agreements regarding change in control became effective
March 11, 2005 and continue through December 31, 2007 and shall extend
automatically to the third anniversary thereof unless we give notice to the
other party prior to the date of such extension that the agreement term will not
be extended. Notwithstanding the foregoing, if a change in control occurs during
the term of the agreements, the term of the agreements will continue through the
second anniversary of the date on which the change in control occurred. Each of
the agreements entitles William A. Carter, Robert E. Peterson and Ransom W.
Etheridge, respectively, to change of control benefits, as defined in the
agreements and summarized below, upon their respective termination of
employment/engagement with our company during a potential change in control, as
defined in the agreements or after a change in control, as defined in the
agreements, when their respective terminations are caused (1) by us for any
reason other than permanent disability or cause, as defined in the agreement (2)
by William A. Carter, Robert E. Peterson and/or Ransom W. Etheridge,
respectively, for good reason as defined in the agreement or, (3) by William A.
Carter, Robert E. Peterson and/or Ransom W. Etheridge, respectively for any
reason during the 30 day period commencing on the first date which is six months
after the date of the change in control.

The benefits for each of the foregoing executives would be as follows:

o A lump sum cash payment of three times his base salary and annual
bonus amounts; and

o Outplacement benefits.

91
Each  agreement  also  provides  that the  executive is entitled to a "gross-up"
payment to make him whole for any federal excise tax imposed on change of
control or severance payments received by him. Dr. Carter's agreement also
provides for the following benefits:

o Continued insurance coverage through the third anniversary of his
termination; and

o Retirement benefits computed as if he had continued to work for the
above period.

Compensation of Directors

The compensation package for non-employee members of the Board of
Directors was changed on September 9, 2003. Board member compensation consists
of an annual retainer of $100,000 to be paid 50% in cash and 50% in our common
stock. On September 9, 2003 the Directors approved a 10 year plan which
authorizes up to 1,000,000 shares for use in supporting this compensation plan.
The number of shares paid shall have a value of $12,500 with the value of the
shares being determined by the closing price of our common stock on the American
Stock Exchange on the last day of the calendar quarter. In addition, all
non-employee directors received some compensation in 2003 for special project
work performed on our behalf. This project work ceased as of September 30, 2003.
All directors have been granted options to purchase common stock under our Stock
Option Plans and/or Warrants to purchase common stock. We believe such
compensation and payments are necessary in order for us to attract and retain
qualified outside directors.

2004 Equity Incentive Plan

Our 2004 Equity Incentive Plan ("2004 Plan") provides for the grant of
non-qualified and incentive stock options, stock appreciation rights, restricted
stock and other stock awards to our employees, directors, officers, consultants
and advisors for the purchase of up to an aggregate of 8,000,000 shares of
common stock. The 2004 plan is administered by the board of directors, which has
complete discretion to select eligible individuals to receive and to establish
the terms of grants under the plan. Stock options awarded under the Equity
Incentive Plan may be exercisable at such times (not later than 10 years after
the date of grant) and at such exercise prices (not less than fair market value
at the date of grant) as the Board may determine. The Board may provide for
options to become immediately exercisable upon a "change in control" as defined
in the plan. The number of shares of common stock available for grant under the
2004 Plan is subject to adjustment for changes in capitalization. As of December
31, 2005, 5,714,320 shares were available for grants under the 2004 Plan 633,080
and 1,652,600 options were issued in 2004 and 2005 respectively. Unless sooner
terminated, the Equity Incentive Plan will continue in effect for a period of 10
years from its effective date

1990 Stock Option Plan

Our 1990 Stock Option Plan, as amended ("1990 Plan"), provides for the
grant of options to our employees, directors, officers, consultants and advisors
for the purchase of up to an aggregate of 460,798 shares of common stock. The
1990 Plan is administered by the Compensation Committee of the board of
directors, which has complete discretion to select eligible individuals to
receive and to establish the terms of option grants. The number of shares of
common stock available for grant under the 1990 Plan is subject to adjustment
for changes in capitalization. As of December 31, 2004 and 2005, 18,881 options
were available for grants under the 1990 Plan. This plan remains in effect until
terminated by the Board of Directors or until all options are issued.

92
401(K) Plan

In December 1995, we established a defined contribution plan, effective
January 1, 1995, entitled the Hemispherx Biopharma employees 401(K) Plan and
Trust Agreement. All of our full time employees are eligible to participate in
the 401(K) plan following one year of employment. Subject to certain limitations
imposed by federal tax laws, participants are eligible to contribute up to 15%
of their salary (including bonuses and/or commissions) per annum. Participants'
contributions to the 401(K) plan may be matched by Hemispherx at a rate
determined annually by the board of directors. Each participant immediately
vests in his or her deferred salary contributions, while our contributions will
vest over one year. See Note 12 to the consolidated financial statements
contained herein.

Compensation Committee Interlocks and Insider Participation

Our Compensation Committee of the Board of Directors consists of , the
Committee Chairman, William Mitchell, M.D., Richard Piani and Dr. Iraj E. Kiani.
Please see Item 13. "Certain Relationships and Related Transactions" below for
more information.

Compensation Committee Report on Compensation

The Compensation Committee makes recommendations concerning salaries and
compensation for our employees and consultants.

The following report of the compensation committee discusses our executive
compensation policies and the basis of the compensation paid to our executive
officers in 2005.

In general, the compensation committee seeks to link the compensation paid
to each executive officer to the experience and performance of such executive
officer. Within these parameters, the executive compensation program attempts to
provide an overall level of executive compensation that is competitive with
companies of comparable size and with similar market and operating
characteristics.

There are three elements in our executive total compensation program, all
determined by individual and corporate performance as specified in the various
employment agreements; base salary, annual incentive, and long-term incentives.

Base Salary

The Summary Compensation Table shows amounts earned during 2005 by our
executive officers. The base compensation of such executive officers is set by
terms of the employment agreement entered into with each such executive officer.
We established the base salaries for Chief Executive Officer, Dr. William A.
Carter under an employment agreement in December 3, 1998 (as amended and
restated on March 11, 2005), which provides for a base salary of $290,888. In
addition, we entered into an agreement with Dr. Carter for his services as a
consultant related to patient development, development of patents and as a
member of our Board of Directors. This agreement establishes a base annual fee
of $207,777. Both agreements are subject to annual cost of living adjustments.
Dr. Carter is entitled to an annual performance bonus of up to 25% of the base
salary of each agreement at the discretion of the compensation committee of the
Board of Directors.


93
On March 11, 2005, we entered into an extended  engagement  agreement with
Robert E. Peterson, Chief Financial Officer retroactive to January 1, 2005 for a
base annual fee of $202,680 until December 31, 2010. Mr. Peterson's agreement
allows for annual cost of living increases and a performance bonus.

On March 11, 2005, we entered into an engagement agreement with Ransom W.
Etheridge, Corporate General Counsel, retroactive to January 1, 2005 for an
annual fee of $96,000 until December 31, 2009.

Annual Incentive

Our Chief Executive Officer and our Chief Financial Officer are entitled
to an annual incentive bonus as determined by the compensation committee based
on such executive officers' performance during the previous calendar year. The
cash bonus awarded to our Chief Executive Officer in 2004 and 2005 and the cash
bonus awarded to the Chief Financial Officer in 2004 and 2005 were determined
based on this provision in their employment agreements.

Long-Term Incentives

We grant long-term incentive awards periodically to align a significant
portion of the executive compensation program with stockholder interest over the
long-term through encouraging and facilitating executive stock ownership.
Executives are eligible to participate in our incentive stock option plans. Our
Chief Executive Officer and President, Dr. William Carter, received a grant of
645,000 stock options in 2005 of which 535,000 were issued to replace options
previously awarded that expired. These options are exercisable at rates varying
from $1.75 to $2.87 per share. The options vested on the date of grant.

On April 26, 2005, our Chief Financial Officer, Robert E. Peterson, was
granted 100,000 stock options exercisable at $1.75 per share expiring on April
26, 2015 unless previously exercised. On December 8, 2005 Mr. Peterson was
granted 10,000 stock options exercisable at $2.61 per share expiring on December
8, 2015.

Ransom Etheridge, our Corporate Secretary and General Counsel, was awarded
100,000 stock options on April 26, 2005 exercisable at $1.75 per share expiring
April 26, 2015, unless previously exercised.

Audit Fees

Represents fees for professional services provided for the audit of our
annual financial statements, services that are performed to comply with
generally accepted auditing standards, and review of our financial statements
included in our quarterly reports and services in connection with statutory and
regulatory filings.

Audit-Related Fees

Represents the fees for assurance and related services that are reasonably
related to the performance of the audit or review of our financial statements.

The Audit Committee has determined that BDO Seidman, LLP's rendering of
these non-audit services is compatible with maintaining auditors independence.
The Board of Directors considers BDO Seidman, LLP to be well qualified to serve
as our independent public accountants. The committee also approved the charges
for services performed in 2005.

100
The Audit  Committee  pre-approves  all  auditing  services  and the terms
thereof (which may include providing comfort letters in connection with
securities underwriting) and non-audit services (other than non-audit services
prohibited under Section 10A(g) of the Exchange Act or the applicable rules of
the SEC or the Public Company Accounting Oversight Board) to be provided to us
by the independent auditor; provided, however, the pre-approval requirement is
waived with respect to the provisions of non-audit services for us if the "de
minimus" provisions of Section 10A (i)(1)(B) of the Exchange Act are satisfied.
This authority to pre-approve non-audit services may be delegated to one or more
members of the Audit Committee, who shall present all decisions to pre-approve
an activity to the full Audit Committee at its first meeting following such
decision.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

(1) Business

Hemispherx Biopharma, Inc. and subsidiaries (the Company) is a
biopharmaceutical company engaged in the clinical development, manufacture,
marketing and distribution of new drug entities based on natural immune system
enhancing technologies for the treatment of viral and immune based chronic
disorders. The Company was founded in the early 1970s, as a contract researcher
for the National Institutes of Health. The Company has established a strong
foundation of laboratory, pre-clinical, and clinical data with respect to the
development of nucleic acids to enhance the natural antiviral defense system of
the human body and to aid the development of therapeutic products for the
treatment of chronic diseases. The Company owns a U.S. Food and Drug
Administration ("FDA") approved GMP (good manufacturing practice) manufacturing
facility in New Jersey.

The Company's flagship products include Ampligen(R) and Alferon N
Injection(R). Ampligen(R) is an experimental drug undergoing clinical
development for the treatment of: Myalgic Encephalomyelitis/Chronic Fatigue
Syndrome ("ME/CFS" or "CFS"), and HIV. In August 2004, we completed a Phase III
clinical trial ("AMP 516") treating over 230 ME/CFS patients with Ampligen(R)
and are in the process of preparing a new drug application ("NDA") to be filed
with the FDA.

In March 2004, the Company completed the step-by-step acquisition from
Interferon Sciences, Inc. ("ISI") of ISI's commercial assets, Alferon N
Injection(R) inventory, a worldwide license for the production, manufacture,
use, marketing and sale of Alferon N Injection(R), as well as, a 43,000 square
foot manufacturing facility in New Jersey and the acquisition of all
intellectual property related to Alferon Injection(R). Alferon N Injection(R) is
a natural alpha interferon that has been approved by the FDA for commercial sale
for the intra-lesional treatment of refractory or recurring external genital
warts in patients 18 years of age or older. The acquisition was completed in
Spring 2004 with the acquisition of all world wide commercial rights.

The consolidated financial statements include the financial statements of
Hemispherx Biopharma, Inc. and its wholly-owned subsidiaries. The Company has
three domestic subsidiaries BioPro Corp., BioAegean Corp. and Core BioTech
Corp., all of which are incorporated in Delaware and are dormant. The Company's
foreign subsidiaries include Hemispherx Biopharma Europe N.V./S.A. established
in Belgium in 1998 and Hemispherx Biopharma Europe S. A. incorporated in
Luxemburg in 2002 which is also dormant. All significant intercompany balances
and transactions have been eliminated in consolidation.

(2) Restatements

(a) On March 29, 2006, after doing additional analysis on guidelines set
forth in EITF 00-27: Application of Issue No. 98-5 to Certain
Convertible Instruments, it was determined that the accounting
treatment for the March 2003, July 2003, October 2003, January 2004
and July 2004 Debentures (collectively, the "Debentures") was
inaccurately reflected in the financial statements for the quarters
and years ended included in our Annual Report on Form 10-K for the
years ended December 31, 2004 and 2003, and for the quarterly
periods ended March 31, 2003, June 30, 2003, September 30, 2003,
March 31, 2004, June 30, 2004, September 30, 2004, March 31, 2005,
June 30, 2005 and September 30, 2005, included within our Quarterly
Reports on Form 10-Q and that, therefore, a restatement of our
financial statements for the periods referenced above was required.
In connection with the initial recording of the Debentures mentioned
above, it was originally determined that the discount related to the
embedded conversion features and warrant issuances calculated at
fair value was approximately $1,607,000, $2,724,000, $2,879,000,
$2,272,000 and $1,260,000 for the March 2003, July 2003, October
2003, January 2004 and July 2004 Debentures, respectively. The
discount derived from determining the fair value of the embedded
conversion feature and warrant issuances is amortized to financing
costs over the life of the debenture or charged to earnings on the
earlier conversion thereof. To properly account for the initial
calculation of the discount, the Company determined, under guidance
from EITF 00-27: Application of Issue No. 98-5 to Certain
Convertible Instruments, the debt discount should be restated for
the March 2003, July 2003, October 2003, January 2004 and July 2004
Debentures to $2,098,000, $2,280,000, $3,177,000, $1,998,000 and
$628,000, respectively. The total impact of this restatement on our
statement of operations was to decrease the net loss for the year
ended December 31, 2004 by $382,000 or $0.01 per share and an
increase in net loss of $301,000 or $0.01 per share for the period
ended December 31, 2003.

F-9
(b)   On March 29, 2006, it was determined  that the accounting  treatment
for the investment banking fees paid to Cardinal Capital, LLC
("Cardinal") in connection with the Debenture issuances was
inaccurately reflected in the financial statements for the quarters
and years ended included in our Annual Report on Form 10-K for the
years ended December 31, 2004 and 2003, and for the quarterly
periods ended March 31, 2003, June 30, 2003, September 30, 2003,
March 31, 2004, June 30, 2004, September 30, 2004, March 31, 2005,
June 30, 2005 and September 30, 2005, included within our Quarterly
Reports on Form 10-Q and that, therefore, a restatement of our
financial statements for the periods referenced above was required.
In connection with the initial recording of the Debentures mentioned
above, it was originally determined that the fair value of the
warrants issued as investment banking fees paid to Cardinal
Securities, LLC, be accounted for as a discount to the underlying
Debentures and amortized over the life of the debenture or charged
to earnings on the earlier conversion thereof. These investment
banking fees should have been capitalized as an asset on the balance
sheet and amortized over the life of the debenture or charged to
earnings on the earlier conversion thereof. In addition, our
calculation of the fair value of the warrants issued to Cardinal as
part of the Debenture issuances as a discount to the Debenture was
determined to be overstated at the time of issuance. The total
impact of this restatement on our statement of operations was to
decrease the net loss for the year ended December 31, 2004 by
$460,000 or $.01 and an increase to the net loss for the year ended
December 31, 2003 of $138,000 or $0.00 per share.

(c) On March 29, 2006, after doing additional analysis on guidelines set
forth in EITF 00-27: Application of Issue No. 98-5 to Certain
Convertible Instruments, it was determined that the accounting
treatment for the conversion price reset on the July 2003, January
2004 and July 2004 debentures was inaccurately reflected in the
financial statements for the quarters and years ended included in
our Annual Report on Form 10-K for the years ended December 31, 2004
and 2003, and for the quarterly periods ended September 2003, March
31, 2004, June 30, 2004, September 30, 2004, March 31, 2005, June
30, 2005 and September 30, 2005, included within our Quarterly
Reports on Form 10-Q and that, therefore, a restatement of our
financial statements for the periods referenced above was required.
A conversion price reset was triggered on the July 2003 Debenture
upon the issuance of the October 2003 Debenture. In addition, a
conversion price reset was triggered on both the January 2004 and
July 2004 debentures upon the closing of the August 2004 Private
Placement (See Note 8 & 9 contained within the consolidated
financial statements contained herein for more details on the
resets). Under the previous accounting treatment, The Company did
not properly account for the conversion price resets on the July
2003, January 2004 and July 2004 debentures.. To properly account
for the conversion price resets, the Company determined, under
guidance from EITF 00-27: Application of Issue No. 98-5 to Certain
Convertible Instruments, an additional debt discount should have
been recorded for the July 2003, January 2004 and July 2004
Debentures of approximately $741,000, $915,000 and $632,000,
respectively. The total impact of this restatement on our statement
of operations was to increase the net loss for the year ended
December 31, 2004 and 2003 by $1,037,000 and $58,000 or $0.02 and
$0.00 per share, respectively.

F-10
(d)   On March 29, 2006, it was determined  that the accounting  treatment
for the warrant conversion price reset on the July 2009 Warrants
(See Note 8 "January 2004 Debenture" within the consolidated
financial statements contained herein for more detail on this
transaction) was inaccurately reflected in the financial statements
for the quarter and year ended included in our Annual Report on Form
10-K for the year ended December 31, 2004, and for the quarterly
period ended March 31, 2005, included within our Quarterly Reports
on Form 10-Q, and that, therefore, a restatement of our financial
statements for the periods referenced above was required. The
warrant price reset on the July 2009 Warrants was triggered upon the
closing of the August 2004 Private Placement and the Company
recorded an additional charge to earnings of $337,000 in 2005 upon
the warrant price reset. This additional charge to earnings in 2005
included $108,000 that pertained to the quarter ended December 31,
2004. The total impact of this restatement on the Company's
statement of operations was to increase the net loss for the year
ended December 31, 2004 by $108,000 or $0.00 per share.

(e) On March 29, 2006, it was determined that the accounting treatment
for the warrant conversion price reset on the May and June 2009
Warrants (See Note 8 within the consolidated financial statements
contained herein for more detail on this transaction) was
inaccurately reflected in the financial statements for the quarter
and year ended included in the Company's Annual Report on Form 10-K
for the year ended December 31, 2004, and for the quarterly period
ended March 31, 2005, included within the Company's Quarterly
Reports on Form 10-Q, and that, therefore, a restatement of the
Company's financial statements for the periods referenced above was
required. The warrant price reset on the May and June 2009 Warrants
was triggered upon the closing of the August 2004 Private Placement
and we recorded an additional charge to earnings of $1,359,000 in
2005 upon the warrant price resets. This additional charge to
earnings in 2005 included $357,000 that pertained to 2004. The total
impact of this restatement on the Company's statement of operations
was to increase the net loss for the year ended December 31, 2004 by
$357,000 or $0.01 per share.

F-11
(f)   On March 29, 2006, it was determined  that the accounting  treatment
for the issuance of the June 2008 Warrants (See Note 8 within the
consolidated financial statements contained herein for more detail
on this transaction) was inaccurately reflected in the financial
statements for the quarter and year ended included in our Annual
Report on Form 10-K for the year ended December 31, 2003, and that,
therefore, a restatement of our financial statements for the periods
referenced above was required. Under the pervious accounting
treatment, the June 2008 Warrants issued as incentive for the March
2003 debenture holders to exercise prior warrant issuances was not
accounted for properly. To properly account for the issuance of the
additional warrants, we determined that we should have recorded a
lower debt discount of approximately $ . The total impact of this
restatement on our statement of operations was to decrease the net
loss for the year ended December 31, 2003 by $1,320,000 or $0.04 per
share.

(g) On March 30, 2006, it was determined that the accounting treatment
for the issuance of the June 2009 Warrants (See Note 8 within the
consolidated financial statements contained herein for more detail
on this transaction) and warrants issued in conjunction with a debt
modification were inaccurately reflected in the financial statements
for the quarters ended June 30, 2004, through September 30, 2005 and
the year ended included in our Annual Report on Form 10-K for the
year ended December 31, 2004, and that, therefore, a restatement of
our financial statements for the periods referenced above was
required. Under the pervious accounting treatment, the intial
issuance of the June 2009 Warrants and the warrants issued in
conjunction with the debt modification were not accounted for
properly. To properly account for the issuance of the additional
warrants, we determined that we should have recorded a lower charge
to earnings of approximately $1,667,000. The total impact of this
restatement on our statement of operations was to decrease the net
loss for the year ended December 31, 2004 by $1,667,000 or $0.04 per
share.


As a result of the corrections of the errors described above, the Company
restated our financial statements included in this Annual Report on Form 10-K as

The Company and the Company's audit committee have discussed the above errors
and adjustments with the Company's current independent registered public
accounting firm and have determined that a restatement is necessary for the
periods described above. This Annual Report on Form 10-K for the fiscal year
ended December 31, 2005 reflects the changes for the annual results for the
years ended December 31, 2003 and December 31, 2004. The Company will file the
Company's Quarterly Reports on Form 10-Q/A for the quarterly periods ended March
31, 2004, June 30, 2004, September 30, 2004, March 31, 2005, June 30, 2005 and
September 31, 2005, as soon as practicable in connection with the restatements
described above.

(3)   Summary of Significant Accounting Policies

(a) Cash and Cash Equivalents

Cash equivalents consist of money market certificates and overnight
repurchase agreements collateralized by money market securities with original
maturities of less than three months, with both a cost and fair value of
$8,813,000 and $3,827,000 at December 31, 2004 and 2005, respectively.

(b) Short-term Investments

Investments with original maturities of more than three months and less
than 12 months and marketable equity securities are considered available for
sale. The investments classified as available for sale include debt securities
and equity securities carried at estimated fair value of $7,924,000 and
$12,377,000 at December 31, 2004 and 2005 respectively. The unrealized gains and
losses are recorded as a component of shareholders' equity.

(c) Investments in unconsolidated affiliates

Investments in companies in which the Company owns 20% or more and not
more than 50% are accounted for using the equity method of accounting.

Investments in companies in which the Company owns less than 20% of and
does not exercise a significant influence are accounted for using the cost
method of accounting.


In May 2000, the Company acquired an interest in Chronix Biomedical Corp.
("CHRONIX"). Chronix focuses upon the development of diagnostics for chronic
diseases. The Company issued 100,000 shares of common stock to Chronix toward a
total equity investment of $700,000. Pursuant to a strategic alliance agreement,
the Company provided Chronix with $250,000 for research and development in an
effort to develop intellectual property on potential new products for diagnosing
and treating various chronic illnesses such as ME/CFS. These costs were expensed
as incurred. The strategic alliance agreement provides the Company certain
royalty rights with respect to certain diagnostic technology developed from this
research and a right of first refusal to license certain therapeutic technology
developed from this research. The strategic alliance agreement provides the
Company with a royalty payment of 10% of all net sales of diagnostic technology
developed by Chronix for diagnosing Chronic Fatigue Syndrome, Gulf War Syndrome
and Human Herpes Virus-6 associated diseases. The royalty continues for the
longer of 12 years from September 15, 2000 or the life of any patent(s) issued
with regard to the diagnostic technology. The strategic alliance agreement also
provides the Company with the right of first refusal to acquire an exclusive
worldwide license for any and all therapeutic technology developed by Chronix on
or before September 14, 2012 for treating Chronic Fatigue Syndrome, Gulf War
Syndrome and Human Herpes Virus-6 associated diseases. During the quarter ended
December 31, 2002 and September 30, 2004 the Company recorded a non-cash charge
of $292,000 and $373,000, respectively, with respect to the Company's investment
in Chronix. This impairment reduces the Company's carrying value to reflect a
permanent decline in Chronix's market value based on its then proposed equity
offerings.

Property and equipment, net $3,303 $3,364
====== ======

Property and equipment consist of land, building, furniture, fixtures,
office equipment, and leasehold improvements and is recorded at cost.
Depreciation and amortization is computed using the straight-line method over
the estimated useful lives of the respective assets, ranging from five to
thirty-nine years. Depreciation and amortization expense was $80,000, $113,000
and $114,000 for 2003, 2004 and 2005, respectively.

Construction in progress consists of funds used for the construction and
installation of the Company's Ampligen(R) raw material production line within
the Company's New Jersey facility. As of December 31, 2005, construction in
progress was $821,000. The Company estimates the total cost of establishing the
production line to be $1,900,000.

(e) Patent and Trademark Rights

Patents and trademarks are stated at cost (primarily legal fees) and are
amortized using the straight line method over the established useful life of 17
years. The Company reviews its patents and trademark rights periodically to
determine whether they have continuing value. Such review includes an analysis
of the patent and trademark's ultimate revenue and profitability potential on an
undiscounted cash flow basis to support the realizability of its respective
capitalized cost. Management's review addresses whether each patent continues to
fit into the Company's strategic business plans. During the years ended December
31, 2003, 2004 and 2005, the Company decided not to pursue the technology in
certain countries for strategic reasons and recorded charges of $5,000, $223,000
and $194,000 respectively. Amortization expense was $122,000, $104,000 and
$87,000 in 2003, 2004 and 2005, respectively. The accumulated amortization as of
December 31, 2003, 2004 and 2005 is $2,150,000, $1,807,000 and $1,572,000,
respectively.

As of December 31, 2005, the weighted average remaining life of the
patents and trademarks was 9 years. Amortization of patents and trademarks for
each of the next five years is as follows: 2006 - $87,000, 2007 - $86,000, 2008
- - $86,000, 2009 - $86,000 and 2010 - $86,000.

(f) Revenue and License Fee Income

The Company executed a Memorandum of Understanding (MOU) in January 2004
with Astellas Pharma ("Astellas"), formally Fujisawa Deutschland GmbH, a major
pharmaceutical corporation, granting them an exclusive option for a limited
number of months to enter a Sales and Distribution Agreement with exclusive
rights to market Ampligen(R) for ME/CFS in Germany, Austria and Switzerland. The
Company received an initial fee of 400,000 Euros (approximately $497,000 US) in
2004. On November 9, 2004, the Company and Astellas terminated the MOU by mutual
agreement. The Company did not agree on the process to be utilized in certain
European Territories for obtaining commercial approval for the sale of
Ampligen(R) in the treatment of patients suffering from Chronic Fatigue Syndrome
(CFS). Instead of a centralized procedure, and in order to obtain an earlier
commercial approval of Ampligen(R) in Europe, the Company has determined to
follow a decentralized filing procedure which was not anticipated in the MOU.
The Company believed that it was in the best interest of the Company's
stockholders to potentially accelerate entry into selected European markets
whereas the original MOU specified a centralized registration procedure.
Pursuant to mutual agreement of the parties the Company refunded 200,000 Euros
to Astellas. The Company has determined that all obligations under the MOU with
Astellas have been fulfilled and, therefore, $241,000 was recorded in September
2005 as other income. Revenue from the sale of Ampligen(R) under cost recovery
clinical treatment protocols approved by the FDA is recognized when the
treatment is provided to the patient.

F-17
Revenues from the sale of Alferon N Injection(R)  are recognized  when the
product is shipped, as title is transferred to the customer. The Company has no
other obligation associated with its products once shipment has occurred.

(g) Net Loss Per Share

Basic and diluted net loss per share is computed using the weighted
average number of shares of common stock outstanding during the period.
Equivalent common shares, consisting of stock options and warrants accounting to
25,935,142 shares, are excluded from the calculation of diluted net loss per
share since their effect is antidilutive.

(h) Accounting for Income taxes

Deferred income tax assets and liabilities are determined based on
differences between the financial statement reporting and tax bases of assets
and Liabilities and are measured using the enacted tax rates and laws in effect
when the differences are expected to reverse. The measurement of deferred income
tax assets is reduced, if necessary, by a valuation allowance for any tax
benefits, which are not expected to be realized. The effect on deferred income
tax assets and liabilities of a change in tax rates is recognized in the period
that such tax rate changes are enacted.

(i) Comprehensive (loss)

Comprehensive (loss) consists of net loss and net unrealized gains
(losses) on securities and is presented in the consolidated statements of
changes in stockholders' equity and comprehensive (loss).

(j) Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses for the reporting
period. Actual results could differ from those estimates.

F-18
(k)   Foreign currency translations

Assets and liabilities of the Company's foreign operations are generally
translated into U.S. dollars at current exchange rates as of balance sheet date.
Revenues and expenses are translated at average exchange rates during each
period. Transaction gains and losses that arise from exchange rate fluctuations
are included in the results of operations as incurred. The resulting translation
adjustments are immaterial for all years presented.

(l) Recent Accounting Standard and Pronouncements:

On December 2004, the FASB issued Statement of Financial Accounting
Standards No. 123 (Revised 2004), "Share-Based Payment" ("SFAS 123R"). On April
14, 2005, the Securities and Exchange Commission issued an amendment to Rule
4-01 of Regulation S-X that allows companies to implement SFAS 123R at the
beginning of their next fiscal year, instead of the next reporting period that
begins after June 15, 2005 as originally required. Accordingly, the Company will
adopt SFAS 123R effective January 1, 2006 using the "modified prospective"
method in which compensation cost is recognized beginning with the effective
date based on (a) the requirements of SFAS 123R for all share-based payments
granted after the effective date and (b) the requirements of SFAS 123 for all
awards granted to employees prior to the effective date of SFAS 123R that remain
unvested on the effective date. In addition, the Company expects to continue to
utilize the Black-Scholes option-pricing model, which is an acceptable option
valuation model in accordance with SFAS 123R, to estimate the value of stock
options granted to employees.

Beyond those restricted stock and stock option awards previously granted,
the Company cannot predict with certainty the impact of SFAS 123R on its future
consolidated financial statements as the type and amount of such awards are
determined on an annual basis and encompass a potentially wide range depending
upon the compensation decisions made by the Compensation Committee of the
Company's Board of Directors. SFAS 123R also requires the benefits of tax
deductions in excess of compensation cost recognized in the financial statements
to be reported as a financing cash flow, rather than an operating cash flow as
currently required under Statement of Financial Accounting Standards No. 95,
"Statement of Cash Flows" ("SFAS 95"). This requirement, to the extent it
exists, will decrease net operating cash flows and increase net financing cash
flows in periods subsequent to adoption. The Company cannot estimate what those
amounts will be in the future because they depend on, among other things, when
employees exercise stock options.

On March 29, 2005, the SEC issued Staff Accounting Bulletin No. 107 ("SAB
107") which expresses the view of the SEC Staff regarding the interaction of
SFAS 123R and certain SEC rules and regulations and provides the staff's views
regarding the valuation of share-based payment arrangements. The Company
believes that the views provided in SAB 107 are consistent with the approach
taken in the valuation and accounting associated with share-based compensation
issued in prior periods as well as those issued during 2005.

In June 2005, the FASB's Emerging Issues Task Force ("EITF") issued EITF
Issue No. 05-02 "The Meaning of "Conventional Convertible Debt Instrument" in
EITF Issue 00-19 "Accounting for Derivative Financial Instruments Indexed to,
and Potentially Settled in, A Company's Own Stock", which retains the exception
in paragraph 4 of EITF Issue No. 00-19 for conventional debt instruments. Those
instruments in which the holder has an option to convert the instrument into a
fixed number of shares (or a corresponding amount of cash at the issuer's
discretion) and its ability to exercise the option is based on either (a) the
passage of time or (b) a contingent event, should be considered "conventional"
for purposes of applying that exception. The consensus should be applied on a
prospective basis for new or modified instruments starting from the third
quarter of 2005. The adoption of EITF No. 05-02 is not expected to have a
material effect on the Company's consolidated financial statements or results of
operations.

F-19
When there is a modification of a convertible debt instrument, the change in the
fair value of an embedded conversion option should be included in the analysis
of determining whether a debt extinguishment has occurred. The change in the
fair value of the embedded conversion option is calculated as the difference
between the fair value of the conversion option immediately prior to and after
the modification. Also, when a modification of a convertible debt instrument
occurs, the change in the fair value of the embedded conversion prior should be
recognized as a discount (or premium) with a corresponding increase (or
decrease) in additional paid-in capital. Lastly, a beneficial feature should not
be recognized or reassessed upon modification of a convertible debt instrument.
The adoption of EITF No. 05-02 is not expected to have a material effect on the
Company's consolidated financial statements or results of operations.

In November 2005, FASB issued FSP FAS 115-1 and FAS 124-1, "The Meaning of
Other-Than-Temporary Impairment and Its Application to Certain Investments"
("FSP FAS 115-1"), which provides guidance on determining when investments in
certain debt and equity securities are considered impaired, whether an
impairment is other-than-temporary, and on measuring such impairment loss. FSP
FAS 115-1 also includes accounting considerations subsequent to the recognition
of an other-than-temporary impairment and requires certain disclosures about
unrealized losses that have not been recognized as other-than-temporary
impairments. FSP FAS 115-1 is required to be applied to reporting periods
beginning after December 15, 2005. The Company is required to adopt FSP FAS
115-1 in the first quarter of 2006. The Company does not expect the adoption of
this statement to have a material impact on the Company's consolidated results
of operations or financial condition.

In November 2004, the FASB issued SFAS No. 151, "Inventory Costs - An
amendment of ARB No. 43, Chapter 4" ("SFAS No. 151"). SFAS No. 151 amends the
guidance in Accounting Research Bulletin No. 43, Chapter 4, "Inventory Pricing,"
to clarify the accounting for abnormal amounts of idle facility expense,
freight, handling costs, and wasted material (spoilage). Additionally, SFAS No.
151 requires that the allocation of fixed production overheads to the cost of
conversion be based on the normal capacity of the production facilities. SFAS
No. 151 is required to be adopted in the first quarter of 2006. The Company has
determined that the adoption of SFAS No. 151 will not have a material impact on
the consolidated financial statements.

In December 2004, the FASB issued Statement of Financial Accounting
Standards No. 153 (SFAS 153"), "Exchanges of Non-monetary Assets-an amendment of
APB Opinion No. 29." SFAS 152 addresses the measurement of exchanges of
non-monetary assets. It eliminates the exception from fair value measurement for
non-monetary exchanges of similar productive assets in paragraph 21(b) of APB
Opinion No. 29 "Accounting for Non-monetary Transactions" and replaces it with
an exception for exchanges that do not have commercial substance. A non-monetary
exchange has commercial substance if the future cash flows of the entity are
expected to change significantly as a result of the exchange. As required by
SFAS 153, the Company adopted this new accounting standard effective July 1,
2005. The adoption of SFAS 153 did not have a material impact on the Company's
financial statements.

F-20
In May 2005,  the FASB issued SFAS No. 154,  Accounting  Changes and Error
Corrections. SFAS No. 154 establishes retrospective application as the required
method for reporting a change in accounting principle in the absence of explicit
transition requirements specific to the newly adopted accounting principle. SFAS
No. 154 also provides guidance for determining whether retrospective application
is impractical. SFAS No. 154 is effective for accounting changes and corrections
of errors made in fiscal years beginning after December 15, 2005. The Company
does not expect that the adoption of SFAS No. 154 will have a material impact on
its results of operations or financial position.

(m) Research and Development Costs

Research and development related to both future and present products are
charged to operation as incurred.

(n) Stock Based Compensation

The Company follows Statement of Financial Accounting Standards (SFAS) No.
123, "Accounting for Stock-Based Compensation." We chose to apply Accounting
Principal Board Opinion 25 and related interpretations in accounting for stock
options granted to the Company's employees.

The Company provides pro forma disclosures of compensation expense under
the fair market value method of SFAS No. 123, "Accounting for Stock-Based
Compensation," and SFAS No. 148, "Accounting for Stock-Based Compensation -
Transition and Disclosure."

The weighted average assumptions used for the years presented are as follows:

Had compensation cost for the Company's option plan been determined using
the fair value method at the grant dates, the effect on the Company's net loss
and loss per share for the years ended December 31, 2003, 2004, and 2005 would
have been as follows:

For stock warrants granted to non-employees, the Company measures fair
value of the equity instruments utilizing the Black-Scholes method if that value
is more reliably measurable than the fair value of the consideration or service
received. The Company amortizes such cost over the related period of service.

The exercise price of all stock warrants granted was equal to or greater
than the fair market value of the underlying common stock as defined by APB 25
on the date of the grant.

The lower stock compensation expense noted above resulted from having a limited
number of shares of Common Stock authorized but not issued or reserved for
issuance upon conversion or exercise of outstanding convertible and exercisable
securities such as debentures, options and warrants prior to the Company's
annual meeting of stockholders in September 2003. Prior to the meeting, to
permit consummation of the sale of the July 2003 Debentures and the related
warrants, Dr. Carter agreed that he would not exercise his warrants or options
unless and until the Company's stockholders approve an increase in the Company's
authorized shares of common stock. For Dr. Carter's waiver of his right to
exercise certain options and warrants prior to approval of the increase in the
Company's authorized shares, the Company have agreed to compensate Dr. Carter.

(o) Accounts Receivable

Concentration of credit risk, with respect to accounts receivable, is limited
due to the Company's credit evaluation process. The Company does not require
collateral on its receivables. The Company's receivables primarily consist of
amounts due from the wholesale drug companies as of December 31, 2005.

(p) Deferred Financing Issuance Costs

Deferred financing issuance costs represent costs incurred by the Company to
issue convertible debt instruments. The costs are being amortized in accordance
with the interest method of accounting over the terms of the debt.

F-22
(q)   Convertible Securities with Beneficial Conversion Features

The March 2003, July 2003, October 2003, January 2004 and July 2004 Debenture
issuances and related embedded conversion features and warrants issuances were
accounted for in accordance with EITF 98-5: Accounting for convertible
securities with beneficial conversion features or contingency adjustable
conversion and with EITF No. 00-27: Application of issue No. 98-5 to certain
convertible instruments. The Company determined the fair values to be ascribed
to detachable warrants issued with the convertible debentures utilizing the
Black-Scholes method. Any discount derived from determining the fair value of
the warrants is amortized to financing costs over the remaining life of the
debenture. The unamortized discount upon the conversion of the debentures is
expensed to financing cost on a pro-rata basis.

(4) Inventories

The Company uses the lower of first-in, first-out ("FIFO") cost or market
method of accounting for inventory.



Inventories consist of the following:

(5) Acquisition of Assets of Interferon Sciences, Inc.

On March 11, 2003, the Company acquired from ISI, ISI's inventory of
Alferon N Injection(R) and a limited license for the production, manufacture,
use, marketing and sale of this product. As partial consideration, the Company
issued 487,028 shares of its common stock to ISI. Pursuant to their agreements
with ISI, the Company registered these shares for public sale and ISI reported
that it sold all of these shares. The Company also agreed to pay ISI 6% of the
net sales of Alferon N Injection(R).

On March 11, 2003, the Company also entered into an agreement to purchase from
ISI all of its rights to the product and other assets related to the product
including, but not limited to, real estate and machinery. For these assets, the
Company issued to ISI an additional 487,028 shares and issued 314,465 shares and
267,296 shares, respectively to the American National Red Cross and GP
Strategies Corporation, two creditors of ISI. The Company guaranteed the market
value of all but 62,500 of these shares to be $1.59 per share on the termination
date. ISI, GP Strategies and the American National Red Cross reported that they
sold all of their shares.

Pursuant to the acquisition agreement, the Company satisfied other liabilities
of ISI which were past due and secured by a lien on ISI's real estate and pays
ISI a 6% royalty on the net sales of products containing natural alpha
interferon.

On May 30, 2003, the Company issued the shares to GP Strategies and the American
National Red Cross. Pursuant to the Company's agreements with ISI and these two
creditors, the Company registered the foregoing shares for public sale. As a

March 2003 Debenture

On March 12, 2003, the Company issued an aggregate of $5,426,000 in
principal amount of 6% Senior Convertible Debentures due January 2005 (the
"March 2003 Debentures") and an aggregate of 743,288 warrants to two investors
in a private placement for aggregate gross proceeds of $4,650,000. The March
2003 Debentures were to mature on January 31, 2005 and bore interest at 6% per
annum, payable quarterly in cash or, subject to satisfaction of certain
conditions, common stock. Any shares of common stock issued to the investors as
payment of interest were valued at 95% of the average closing price of the
common stock during the five consecutive business days ending on the third
business day immediately preceding the applicable interest payment date.
Pursuant to the terms and conditions of the March 2003 Debentures, the Company
pledged all of the Company's assets, other than the Company's intellectual
property, as collateral and were subject to comply with certain financial and
negative covenants, which include but were not limited to the repayment of
principal balances upon achieving certain revenue milestones. The March 2003
debenture, at issuance, was recorded at a discount of $4,194,520 due to the fair
value ascribed to the detachable warrants using the Black-Scholes Method and the
effect of a beneficial conversion feature.

The March 2003 Debentures were convertible at the option of the investors
at any time through January 31, 2005 into shares of the Company's common stock.
The conversion price under the March 2003 Debentures was fixed at $1.46 per
share, subject to adjustment for anti-dilution protection for issuance of common
stock or securities convertible or exchangeable into common stock at a price
less than the conversion price then in effect.

The investors also received Warrants to acquire at any time through March
12, 2008 an aggregate of 743,288 shares of common stock at a price of $1.68 per
share. All of these warrants have been exercised.

On June 25, 2003, the Company issued to each of the March 2003 Debenture
holders warrants to acquire at any time through June 25, 2008 an aggregate of
1,000,000 shares of common stock at a price of $2.40 per share (the "June 2008
Warrants"). These warrants were issued as incentive for the debenture holders to
exercise prior warrant issuances. This issuance, as restated, resulted in an
additional debt discount to the March 2003 Debentures of $1,320,000 to be
amortized over the remaining life of the debenture or in the event of conversion
written off to financing costs on pro-rata basis. Pursuant to the Company's
agreement with the March 2003 Debenture holders, the Company registered the
shares issuable upon exercise of these June 2008 Warrants for public sale.

F-27
On May 14, 2004, in  consideration  for the March 2003 Debenture  holders'
exercise of all of the June 2008 Warrants, the Company issued to the holders
warrants (the "May 2009 Warrants") to purchase an aggregate of 1,300,000 shares
of the Company's common stock. The Company issued 1,000,000 shares of common
stock and received gross proceeds of $2,400,000 from the exercise of the June
2008 Warrants.

The May 2009 Warrants are to acquire at any time commencing on November
14, 2004 through April 30, 2009 an aggregate of 1,300,000 shares of common stock
at a price of $4.50 per share. This transaction generated a non-cash charge of
approximately $2,355,000 in financing costs during the second quarter of 2004.
This was written off as the March 2003 Debenture holders had fully converted
their note in 2003. Upon completion of the August 2004 Private Placement (see
below), the exercise price was lowered to $4.008 per share. On May 14, 2005, the
exercise price of these May 2009 Warrants was reset again to the lesser of the
exercise price then in effect or a price equal to the average of the daily price
of the common stock between May 15, 2004 and May 13, 2005. The exercise price
(and the reset price) under the May 2009 Warrants also is subject to adjustments
for anti-dilution protection similar to those in the other Warrants.
Notwithstanding the foregoing, the exercise price as reset or adjusted for
anti-dilution, will in no event be less than $4.008 per share. The Company
recorded an additional charge to financing costs of $39,000 to account for the
reset of the exercise price of these warrants.

As of December 31, 2003, the investors had converted the total $5,426,000
principal of the March 2003 Debentures into 3,716,438 shares of the Company's
common stock. Financing costs and interest expense incurred for the year ended
December 31, 2003, on the March 2003 Debenture amounted to $3,703,166 and
$112,000, respectively. The interest due on this debenture was paid in cash of
$17,000 with $94,000 being paid by the issuance of shares of the Company's
common stock. The investor exercised all 743,288 warrants in July 2003 which
produced gross proceeds in the amount of approximately $1,249,000.


July 2003 Debenture

On July 10, 2003, the Company issued an aggregate of $5,426,000 in
principal amount of 6% Senior Convertible Debentures due July 31, 2005 (the
"July 2003 Debentures") and an aggregate of 507,102 Warrants (the "July 2008
Warrants") in a private placement for aggregate proceeds of $4,650,000. Pursuant
to the terms of the July 2003 Debentures, $1,550,000 of the proceeds from the
sale of the July 2003 Debentures were to have been held back and released to the
Company if, and only if, the Company acquired ISI's facility with in a set
timeframe (see Note 5 above). These funds were released to the Company in
October 2003 although the Company had not acquired ISI's facility at that time.
The July 2003 Debentures matured on July 31, 2005 and bore interest at 6% per
annum, payable quarterly in cash or, subject to satisfaction of certain
conditions, common stock. Any shares of common stock issued to the investors as
payment of interest were valued at 95% of the average closing price of the
common stock during the five consecutive business days ending on the third
business day immediately preceding the applicable interest payment date. The
July 2003 debenture, at issuance, was recorded at a discount of $3,587,000 due
to the fair value ascribed to the warrant using Black-Scholes Method and the
effect of a beneficial conversion feature.

F-28
The July 2003 Debentures  were  convertible at the option of the investors
at any time through July 31, 2005 into shares of the Company's common stock. The
conversion price under the July 2003 Debentures was fixed at $2.14 per share;
however, as part of the subsequent debenture placement closed on October 29,
2003 (see below), the conversion price under the July 2003 Debentures was
lowered to $1.89 per share. The conversion price was subject to adjustment for
anti-dilution protection for issuance of common stock or securities convertible
or exchangeable into common stock at a price less than the conversion price then
in effect. In addition, in the event that the Company did pay the redemption
price at maturity, the Debenture holders, at their option, may have converted
the balance due at the lower of (a) the conversion price then in effect and (b)
95% of the lowest closing sale price of the Company's common stock during the
three trading days ending on and including the conversion date. In 2003, the
Company recorded a debt discount of approximately $741,000 upon the conversion
price reset to $1.89 per share. The additional debt discount is amortized over
the remaining life of the debenture or in the event of a conversion written off
to financing costs on a pro-rata basis.

The July 2008 Warrants received by the investors, as amended, were an
aggregate of 507,102 shares of common stock at a price of $2.46 per share. The
amended Warrants did not result in any additional debt. These Warrants were
exercised in July 2004 which produced gross proceeds in the amount of
$1,247,000.

As of December 31, 2004, the investors had converted the total $5,426,000
principal of the July Debentures into 2,870,900 shares of common stock.

The Company recorded financing costs for the years ended December 31, 2004
and 2003, with regard to the July 2003 Debentures of $2,516,000 and $1,281,000,

On October 29, 2003, the Company issued an aggregate of $4,142,357 in
principal amount of 6% Senior Convertible Debentures due October 31, 2005 (the
"October 2003 Debentures") and an aggregate of 410,134 Warrants (the "October
2008 Warrants") in a private placement for aggregate gross proceeds of
$3,550,000. Pursuant to the terms of the October 2003 Debentures, $1,550,000 of
the proceeds from the sale of the October 2003 Debentures were held back and
were to be released to the Company if, and only if, the Company acquired ISI's
facility within 90 days of January 26, 2004 and provide a mortgage on the
facility as further security for the October 2003 Debentures (see Note 5 above).
In April 2004, the Company acquired the facility and the Company subsequently
provided the mortgage of the facility to the Debenture holders and the above
funds were released. The October 2003 Debentures were to mature on October 31,
2005 and bore interest at 6% per annum, payable quarterly in cash or, subject to
satisfaction of certain conditions, common stock. Any shares of common stock
issued to the investors as payment of interest shall be valued at 95% of the
average closing price of the common stock during the five consecutive business
days ending on the third business day immediately preceding the applicable
interest payment date. The October 2003 debenture, at issuance, was recorded at
a discount of $3,177,000 due to the fair value ascribed to the warrants using
Black-Scholes and the effect of the beneficial conversion feature.

F-29
In October 2005, the Company entered into an amendment  agreement with the
October 2003 Debenture holders to amend the maturity date from October 31, 2005
to June 30, 2007, and increase the interest rate from 6% to 7% (see "Debenture
Agreement Amendment" below for more details).

Upon completing the sale of the October 2003 Debentures, the Company
received $3,275,000 in net proceeds consisting of $1,725,000 from the October
2003 Debentures and $1,550,000 that had been withheld from the July 2003
Debentures. As noted above, pursuant to the terms of the October 2003
Debentures, $1,550,000 of the proceeds from the sale of the October 2003
Debentures had been held back. However, these proceeds were released to the
Company in April 2004. As required by the Debentures, the Company has provided a
mortgage on the ISI facility as further security for the Debentures.

The October 2003 Debentures are convertible at the option of the investors
at any time through October 31, 2005 into shares of the Company's common stock.
The conversion price under the October 2003 Debentures is fixed at $2.02 per
share, subject to adjustment for anti-dilution protection for issuance of common
stock or securities convertible or exchangeable into common stock at a price
less than the conversion price then in effect. In addition, in the event that
the Company does not pay the redemption price at maturity, the Debenture
holders, at their option, may convert the balance due at the lower of (a) the
conversion price then in effect and (b) 95% of the lowest closing sale price of
the Company's common stock during the three trading days ending on and including
the conversion date.

The October 2008 Warrants, as amended, received by the investors were to
acquire an aggregate of 410,134 shares of common stock at a price of $2.32 per
share. The amended Warrants resulted in an additional debt discount of
approximately $53,000 in 2004 to be amortized over the remaining life of the
October 2003 debenture or in the event of conversion be written off to financing
costs on a pro-rata basis. These Warrants were exercised in July 2004 which
produced gross proceeds in the amount of approximately $952,000.

As noted above, on July 13, 2004, in consideration for the Debenture
holders' exercise of all of the July 2003 and October 2003 Warrants amounting to
approximately $2,199,000 in gross proceeds, the Company issued to these holders
warrants (the "June 2009 Warrants") to purchase an aggregate of 1,300,000 shares
of common stock since the July 2003 debenture was fully converted in July 2004.
The issuance of these warrants resulted in an additional debt discount to the
October 2003 Debenture, as restated, of $1,515,000 and a financing charge, as
restated, of $2,128,000. The additional debt discount of $1,515,000 will be
amortized over the remaining life of the debenture.

F-30
The June 2009  Warrants are to acquire at any time  commencing  on January
13, 2005 through June 30, 2009 an aggregate of 1,300,000 shares of common stock

June 2009 Warrants was reset to the lesser of the exercise price then in effect
or a price equal to the average of the daily price of the common stock between
July 14, 2004 and July 12, 2005. The exercise price (and the reset price) under
the June 2009 Warrants also is subject to adjustments for anti-dilution
protection similar to those in the other Warrants. Notwithstanding the
foregoing, the exercise price as reset or adjusted for anti-dilution, will in no
event be less than $3.33 per share. Upon completion of the August 2004 Private
Placement (see below), the exercise price was lowered to $3.33 per share. The
Company agreed to register the shares issuable upon exercise of the June 2009
Warrants pursuant to substantially the same terms as the registration rights
agreements between the Company and the holders. Pursuant to this obligation, the
Company has registered the shares.

The Company has paid $1,300,000 into the debenture cash collateral account
as required by the terms of the October 2003 Debentures. The amounts paid
through December 31, 2005 have been accounted for as advances receivable and are
reflected as such on the accompanying balance sheet as of December 31, 2005. The
cash collateral account provides partial security for repayment of the
outstanding Debentures in the event of default.

As of December 31, 2005, the investors had converted $2,071,178 principal
amount of the October 2003 Debenture into 1,025,336 shares of Common Stock. The

principal amount of 6% Senior Convertible Debentures due January 31, 2006 (the
"January 2004 Debentures"), an aggregate of 790,514 warrants (the "July 2009
Warrants") and 158,103 shares of common stock, and Additional Investment Rights
(to purchase up to an additional $2,000,000 principal amount of January 2004
Debentures commencing in six months) in a private placement for aggregate net
proceeds of $3,695,000. The January 2004 Debentures mature on January 31, 2006
and bear interest at 6% per annum, payable quarterly in cash or, subject to
satisfaction of certain conditions, common stock. Any shares of common stock
issued to the investors as payment of interest shall be valued at 95% of the
average closing price of the common stock during the five consecutive business
days ending on the third business day immediately preceding the applicable
interest payment date. Pursuant to the terms of the January 2004 debentures,
commencing July 26, 2004, the Company began to repay the then outstanding
principal amount under the Debentures in monthly installments amortized over 18
months in cash or, at the Company's option, in shares of common stock. Any
shares of common stock issued to the investors as installment payments shall be
valued at 95% of the average closing price of the common stock during the 10-day
trading period commencing on and including the eleventh trading day immediately
preceding the date that the installment is due. The January 2004 debenture, at
issuance, was recorded at a discount of $2,463,000 due to the fair value of the
warrants using Black-Scholes and the effect of the beneficial conversion
feature.

F-31
The January 2004 Debentures are convertible at the option of the investors
at any time through January 31, 2006 into shares of the Company's common stock.
The conversion price under the January 2004 Debentures was fixed at $2.53 per
share, subject to adjustment for anti-dilution protection for issuance of common
stock or securities convertible or exchangeable into common stock at a price
less than the conversion price then in effect. In addition, in the event that
the Company does not pay the redemption price at maturity, the Debenture
holders, at their option, may convert the balance due at the lower of (a) the
conversion price then in effect and (b) 95% of the lowest closing sale price of
the Company's common stock during the three trading days ending on and including
the conversion date. Upon completion of the August 2004 Private Placement (see
Note 9), the conversion price was lowered to $2.08 per share. The Company
recorded an additional debt discount as restated (see Note 2), of approximately
$915,000 due to this conversion price reset.

In October 2005, the Company entered into an amendment agreement with the
January 2004 Debenture holders to amend the maturity date from October 31, 2005
to June 30, 2007, and increase the interest rate from 6% to 7% (see "Debenture
Agreement Amendment" below for more details).

There are two classes of July 2009 Warrants received by the Investors:
Class A and Class B. The Class A warrants are to acquire any time from July 26,
2004 through July 26, 2009 an aggregate of up to 395,257 shares of common stock
at a price of $3.29 per share. The Class B warrants are to acquire any time from
July 26, 2004 through July 26, 2009 an aggregate of up to 395,257 shares of
common stock at a price of $5.06 per share. On January 27, 2005, the exercise
price of these July 2009 Class A and Class B Warrants were reset to the lesser
of their respective exercise price then in effect or a price equal to the
average of the daily price of the common stock between January 27, 2004 and
January 26, 2005. The exercise price (and the reset price) under the July 2009
Warrants also is subject to similar adjustments for anti-dilution protection.
Notwithstanding the foregoing, the exercise prices as reset or adjusted for
anti-dilution, will in no event be less than $2.58 per share. Upon completion of
the August 2004 Private Placement (see Note 9), the exercise price was lowered
to $2.58 per share. In 2004, as restated, and 2005, the Company recorded an
additional charge to financing costs of $108,000 and $228,000 respectively, to
account for the reset of the exercise price of the July 2009 warrants to $2.58
per share.

As of December 31, 2005, the investors had made installment payments of
$1,888,888 and converted $746,510 principal amount of the January 2004
Debentures into 1,094,149 and 347,000 shares of common stock, respectively. The
remaining principal on these debentures was $1,364,602 as of December 31, 2005.

The Company recorded financing costs for the years ended December 31, 2005
and 2004 with regard to the January 2004 Debentures of $1,486,000 and
$1,750,000, respectively. Interest expense for the years ended December 31, 2005
and 2004, with regard to the January 2004 Debentures was $145,000 and $207,000,
respectively.


F-32
July 2004 Debentures

Pursuant to the Additional Investment Rights issued in connection with the
January 2004 and July 2004 debentures, the Company issued to the investors an
additional $2,000,000 principal amount of January 2004 Debentures (the July 2004
Debentures"). The July 2004 Debentures are identical to the January 2004
Debentures except that the conversion price is $2.58. The investors exercised
the Additional Investment Rights on July 13, 2004 and the Company received net
proceeds of $1,860,000. Upon completion of the August 2004 Private Placement
(see Note 9), the conversion price was lowered to $2.08 per share. The July 2004
debentures, at issuance, were recorded at a discount of $628,000 due to the
embedded conversion feature and the fair value of the warrants utilizing the
Black-Scholes Method. The Company recorded a reduction in debt discount of
approximately $628,000 upon the conversion price reset to $2.08 per share, which
is being amortized over the remaining life of the debenture.

In October 2005, the Company entered into an amendment agreement with the
July 2004 Debenture holders to amend the maturity date from October 31, 2005 to
June 30, 2007, and increase the interest rate from 6% to 7% (see "Debenture
Agreement Amendment" below for more details).

As of December 31, 2005, the Company made installment payments of $500,000
resulting in the issuance of 331,669 shares of the Company's common stock. The
Debenture holders had not converted any portion of this debenture as of December
31, 2005.

The Company recorded financing costs for the years ended December 31, 2005
and 2004 with regard to the July 2004 Debentures of $808,000 and $297,000,
respectively. Interest expense for the years ended December 31, 2005 and 2004,
with regard to the January 2004 Debentures was $113,000 and $61,000,
respectively.

Debenture Agreement Amendment

On October 6, 2005, the Company entered into a material definitive
agreement with the October 2003, January 2004 and July 2004 debenture holders to
1) amend the remaining outstanding debentures that were to mature on October 31,
2005 (as amended, the "Series A Debenture") and the two traunches of outstanding
debentures due to mature on January 31, 2006 (as amended, respectively, the
"Series B and Series C Debentures"), to a maturity date of June 30, 2007, 2) to
increase the interest rate from 6% per annum to 7% per annum. In consideration
for extending the maturity date of the outstanding debentures, the Company
issued an aggregate of 225,000 Warrants (the "October 2009 Warrants") to the
debenture holders to acquire common stock at a price of $2.50 per share at any
time from October 31, 2005 through October 31, 2009. The October 2009 Warrants
contain provisions for adjustment of the exercised price in the event of certain
anti-dilution events. The Company agreed to register 135% of the shares issuable
as interest shares that might result due to the amendments to the Debentures and
issuable upon exercise of the October 2009 Warrants.

F-33
The  above  transaction  and  amendment  to  the  existing  terms  of  the
above-mentioned debentures would fall under EITF 96-19, "Debtor's Accounting for
a Modification or Exchange of Debt Instruments". This EITF discussed and reached
a consensus that a substantial modification of terms should be accounted for,
and reported in the same manner as, an extinguishment. Any modification of a
debt instrument between a debtor and creditor in a non-troubled debt situation
is deemed to be a substantial modification in the event the present value of the
cash flows under the new terms of the new debt instrument is at least 10 percent
different from the present value of the remaining cash flows under the terms of
the original instrument. In the event the cash flow effect of the present value
basis is less than 10 percent, the debt instruments are not considered to be
substantially different. The discount rate to be used to calculate the present
value of the cash flows is the effective interest rate of the original debt
instrument. Accordingly, the Company has treated the change in terms to the
original debentures as non-substantial in nature and have not accounted for such
modification as an extinguishment of debt, but rather a debt modification. In
addition, the 225,000 warrants issued to the debenture holders as consideration
for extending the maturity date were valued using the Black-Scholes method was
$556,000 and recorded as additional debt discount on the July 2004 Debenture.
The discount will be amortized as interest expense over the new term of the debt
instrument. Any costs incurred by third parties were expensed as incurred.

Registration Rights Agreements

The Company entered into Registration Rights Agreements with the investors
in connection with the issuance of (i) the above Debentures; (ii) the June 2008,
July 2008, October 2008, July 2009, and May 2009 Warrants (collectively, the
"Warrants"); and (iii) the shares issued in January 2004. Pursuant to the
Registration Rights Agreements the Company has registered on behalf of the
investors the shares issued to them in January 2004 and 135% of the shares
issuable upon conversion of the Debentures and upon exercise of all of the
Warrants. If, subject to certain exceptions, sales of all shares so registered
cannot be made pursuant to the registration statements, then the Company will be
required to pay to the investors their pro rata share of $.00067 times the
outstanding principal amount of the relevant Debentures for each day the above
condition exists.

Investment Banking Fees

By agreement with Cardinal Securities, LLC, for general financial advisory
services and in conjunction with the private debenture placements in July and
October 2003 and in January and July 2004, the Company paid Cardinal Securities,
LLC an investment banking fee equal to 7% of the investments made by the
Debenture holders and issued to Cardinal the following warrants to purchase
common stock: (i) 112,500 exercisable at $2.57 per share; (ii) 87,500
exercisable at $2.42 per share; and (iii) 100,000 exercisable at $3.04 per
share. The $2.57 warrants expire on July 10, 2008, the $2.42 warrants expire on
October 29, 2008 and the $3.04 warrants expire on January 5, 2009. With regard
to the exercise of the June 2008 Warrants and issuance of the May 2009 Warrants,
Cardinal received an investment banking fee of 7%, half in cash and half in
shares. With regard to the exercise of the Additional Investment Rights, the
July 2008 and October 2008 Warrants and issuance of the July 2009 Warrants,
Cardinal received an investment banking fee of 7%, $146,980 in cash and 22,703
in shares as well as 50,000 warrants exercisable at $4.07 expiring on July 12,
2009. By agreement with Cardinal, the Company has registered all of the
foregoing shares and shares issuable upon exercise of the above mentioned
warrants for public resale. As a result of all of the transactions discussed
above, the Company recorded $715,000, as restated as deferred financing costs on
the balance sheet.

F-34
Section 713 of the American Stock Exchange Company Guide

As discussed below, Section 713 of the American Stock Exchange ("AMEX")
Company Guide provides that the Company must obtain stockholder approval before
issuance, at a price per share below market value, of common stock, or
securities convertible into common stock, equal to 20% or more of the Company's
outstanding common stock (the "Exchange Cap"). The Debentures and Warrants have
provisions that require us to pay cash in lieu of issuing shares upon conversion
of the Debentures or exercise of the Warrants if the Company is prevented from
issuing such shares because of the Exchange Cap. In May 2004, the Debenture
holders agreed to amend the provisions of these Debentures and Warrants to limit
the maximum amount of funds that the holders could receive in lieu of shares
upon conversion of the Debentures and/or exercise of the Warrants in the event
that the Exchange Cap was reached to 119.9% of the conversion price of the
relevant Debentures and 19.9% of the relevant Warrant exercise price. See below
for the accounting effect on this matter.

Taken separately, the March, July, October and January 2004 debenture
transactions do not trigger Section 713. However, the AMEX took the position
that these transactions should be aggregated and, as such, stockholder approval
was required for the issuance of common stock for a portion of the potential
exercise of the warrants and conversion of the Debentures in connection with the
January 2004 Debentures. The amount of potential shares that the Company could
exceed the Exchange Cap amounted to approximately 1,299,000. In accordance with
EITF 00-19, Accounting For Derivative Financial Instruments Indexed to and
Potentially Settled in a Company's Own Stock, the Company recorded on January
26, 2004, a redemption obligation of approximately $1,244,000. This liability
represented the fair market value of the warrants and beneficial conversion
feature related to the 1,299,000 shares.

In addition, in accordance with EITF 00-19, the Company revalued this
redemption obligation associated with the beneficial conversion feature and
warrants as of March 31, 2004. The Company recorded an additional redemption
obligation and finance charge of $947,000 as a result of this revaluation. Upon
stockholder approval, the Company's redemption obligation was recorded as
additional paid in capital as of the date approval was received.

The requisite stockholder approval was obtained at the Company's Annual
Meeting of Stockholders on June 23, 2004. In accordance with EITF 00-19, the
Company revalued this redemption obligation associated with the beneficial
conversion feature and warrants as of June 23, 2004. The Company recorded a
reduction in the value of the redemption obligation and financing charge of
$260,000 as a result of this revaluation. In addition, upon receiving the
requisite stockholder approval, this redemption obligation was reclassified as
additional paid in capital as of the date the approval was received or June 23,
2004.

Accounting Guidance

The March, July, October, January 2004 and July 2004 issuances of 6%
Senior Convertible Debentures in the principal amounts of $5,426,000,
$5,426,000, $4,142,357 and $4,000,000 and $2,000,000 respectively and related
embedded conversion features and warrants issuances were accounted for in
accordance with EITF 98-5: Accounting for convertible securities with beneficial
conversion features or contingency adjustable conversion and with EITF No.
00-27: Application of issue No. 98-5 to Certain convertible instruments. The
Company determined the fair values to be ascribed to detachable warrants issued
with the convertible debentures utilizing the Black-Scholes method. In addition,
the Company, upon the debenture holders conversion of any debt principle, would
write off the pro-rata portion of the debt discount applicable to the
conversion.

F-35
Collateral and Financial Covenants

Pursuant to the terms and conditions of all of the outstanding Debentures,
the Company has pledged all of the Company's assets, other than the Company's
intellectual property, as collateral, and the Company is subject to comply with
certain financial covenants. As of December 31, 2005, the Company was in
compliance with debt covenants contained within the Company's debenture
agreements.

In connection with the Debenture agreements, the Company has outstanding
letters of credit of $1 million as additional collateral.


(9) Stockholders' Equity

(a) Preferred Stock

The Company is authorized to issue 5,000,000 shares of $.01 per value
preferred stock with such designations, rights and preferences as may be
determined by the board of directors. There were no preferred shares issued and
outstanding at December 31, 2004 and 2005.

(b) Common Stock

On July 31, 2003, we had approximately 104,000 shares of the Company's
$.001 authorized shares of $.001 par value Common Stock that were not issued or
reserved for issuance. In order to accommodate the shares needed for the July
2003 Debenture, Dr. Carter, the Company's Chief Executive Officer and Cardinal
Capital, the placement agent, agreed that they would not exercise their warrants
or options unless and until the Company's stockholders approved an increase in
the Company's authorized shares of common stock. This action freed up 3,206,650
shares.

The Company's stockholders approved an amendment to the Company's
corporate charter at the Annual Shareholder meeting held in Philadelphia, PA on
September 10, 2003. This amendment increased the Company's authorized shares
from 50,000,000 to 100,000,000.

As of December 31, 2004 and 2005, 49,631,766 and 56,264,155 shares, net of
shares held in the treasury, were outstanding, respectively.

(c) Minority Shareholder Interest

On March 20, 2002 the Company's European Subsidiary Hemispherx Biopharma
Europe, S.A. ("Hemispherx, S.A.") entered into a Sales and Distribution
agreement with Laboratorios del Dr. Esteve S.A. ("Esteve")(Note 18). Pursuant to
the terms of the Agreement, Esteve was granted the exclusive right to market
Ampligen(R) in Spain, Portugal and Andorra for the treatment of Myalgic
Encephalitis/Chronic Fatigue Syndrome ("ME/CFS"). In addition to other terms and
other projected payments, Esteve paid an initial and non refundable fee of
625,000 Euros (approximately $563,000) to Hemispherx S.A. on April 24, 2002 as
the first part of a series of milestone based payments.

F-36
During March 2002,  Hemispherx  was  authorized  to issue up to 22,000,000
Euros of seven percent (7%) convertible preferred securities. Such securities
are guaranteed by the parent company and are convertible into a specified number
of shares of Hemispherx S.A. pursuant to the securities agreement. Conversion is
to occur on the earlier of an initial public offering of Hemispherx S.A. on a
European stock exchange or September 30, 2003.

Esteve purchased 1,000,000 Euros of Hemispherx Biopharma Europe S.A.'s
convertible preferred equity certificates on May 23, 2002. During 2002, the
terms and conditions of these securities were changed so that these preferred
equity certificates could be converted into the common stock of Hemispherx
Biopharma, Inc. in the event that a European IPO was not completed by September
30, 2003. The conversion rate was 300 shares of Hemispherx Biopharma, Inc.'s
common shares for each 1,000 Euro convertible preferred certificate. As a result
the Company recorded approximately $946,000 as minority interest in subsidiary
on its balance sheet at December 31, 2002.

On December 18, 2002, we proposed that Esteve convert their convertible
preferred equity certificates into Hemispherx common stock pursuant to the terms
of the agreement and all unpaid dividends at the market price on that conversion
date. On January 9, 2003, Esteve accepted the Company's proposal and we
registered these shares for public sale.

On March 13, 2003, we issued 347,445 shares of the Company's common stock
to Provesan SA, an affiliate of Esteve S.A., in exchange for 1,000,000 Euros of
convertible preferred equity certificates and any unpaid dividends. As a result
of the exchange, the minority interest in subsidiary was transferred to
stockholders' equity on such date.

The contingent conversion price was more than the then market value of the
parent company's or subsidiaries' common stock at each of the respective
measurement dates. As a result and in accordance with Emerging Issues Task Force
(EITF) No. 00-27 "Application of Issue No. 98-5 (Accounting for Convertible
Securities with Beneficial Conversion Features or Contingently Adjustable
Conversion Ratios) to Certain Convertible Instruments", the Company did not
ascribe any value to any contingent conversion feature.

(c) Equity Financing

On August 5, 2004, the Company closed a private placement with select
institutional investors ("August 2004 Private Placement") of approximately
3,617,300 shares of its Common Stock and warrants to purchase an aggregate of up
to approximately 1,085,200 shares of its Common Stock. Jefferies & Company, Inc.
acted as Placement Agent for which it received a fee and warrants to purchase
Common Stock. The Company raised approximately $6,984,000 net proceeds from this
private offering.

The Warrant issued to each purchaser is exercisable for up to 30% of the
number of shares of Common Stock purchased by such Purchaser, at an exercise
price equal to $2.86 per share. Each Warrant has a term of five years and is
fully exercisable from the date of issuance. Pursuant to the Registration Rights
Agreement, made and entered into as of August 5, 2004 (the "Rights Agreement"),
the Company registered the resales of the shares issued to the Purchasers and
shares issuable upon the exercise of the Warrants.

F-37
By agreement with Cardinal Securities, LLC, for general financial advisory
services and in conjunction with the August 2004 Private Placement with select
institutional investors, the Company paid Cardinal Securities, LLC an investment
banking fee of $140,000. The Company paid Cardinal one-half of the fee in cash
with the remainder being paid with the issuance of 50,000 warrants to purchase
common stock exercisable at $2.50 per share expiring on March 31, 2010 and
46,667 shares of common stock. By agreement with Cardinal, the Company has
agreed to register all of the foregoing shares and shares issuable upon exercise
of the above mentioned warrants for public resale.

Closing of the August 2004 Private Placement triggered the anti-dilution
provisions of the January 2004 Debentures and the July 2004 Debentures and the
July 2009 Warrants and the June 2009 Warrants. The conversion price adjustment
for the Debentures noted above resulted in an adjustment of $1,320,000 in the
third quarter 2004 to the Debenture discount and additional paid-in-capital
using the Black-Scholes Method.

On July 8, 2005, the Company entered into a common stock purchase
agreement with Fusion Capital Fund II, LLC ("Fusion Capital"), pursuant to which
Fusion Capital has agreed, under certain conditions, to purchase on each trading
day $40,000 of the Company's common stock up to an aggregate of $20.0 million
over approximately a 25 month period, subject to earlier termination at the
Company's discretion. In the Company's discretion, it may elect to sell less
common stock to Fusion Capital than the daily amount and we may increase the
daily amount as the market price of the Company's stock increases. The purchase
price of the shares of common stock will be equal to a price based upon the
future market price of the common stock without any fixed discount to the market
price. Fusion Capital does not have the right or the obligation to purchase
shares of the Company's common stock in the event that the price of the common
stock is less than $1.00.

Pursuant to the Company's agreement with Fusion Capital, the Company has
registered for public sale by Fusion Capital up to 10,795,597 shares of our
common stock. However, in the event that the Company decides to issue more than
10,113,278, i.e. greater than 19.99% of the outstanding shares of common stock
as of the date of the agreement, the Company would first seek stockholder
approval in order to be in compliance with American Stock Exchange rules. As of
December 31, 2005, Fusion Capital has purchased 4,007,255 shares amounting to
approximately $8,034,000 in gross proceeds to the Company.

In connection with entering into the above agreement with Fusion Capital,
the Company, in July 2005, issued to Fusion Capital 402,798 shares of its common
stock. 392,798 of these shares represented 50% of the commitment fee due Fusion
Capital with the remaining 10,000 shares issued as reimbursement for expenses.
An additional 392,799 shares, representing the remaining balance of the
commitment, are issuable in conjunction with daily purchases of common stock by
Fusion Capital. These additional commitment shares will be issued in an amount
equal to the product of (x) 392,799 and (y) the Purchase Amount Fraction. The
"Purchase Amount Fraction" means a fraction, the numerator of which is the
purchase price at which the shares are being purchased by Fusion Capital and the
denominator of which is $20,000,000. As of December 31, 2005, Fusion Capital was
issued 263,713 shares towards this commitment fee.

F-38
(d)   Common Stock Options and Warrants

(i) Stock Options

The 1990 Stock Option Plan provides for the grant of options to purchase
up to 460,798 shares of the Company's Common Stock to employees, directors, and
officers of the Company and to consultants, advisors, and other persons whose
contributions are important to the success of the Company. The recipients of
options granted under the 1990 Stock Option Plan, the number of shares to be
converted by each option, and the exercise price, vesting terms, if any,
duration and other terms of each option shall be determined by the Company's
board of directors or, if delegated by the board, its Compensation Committee. No
option is exercisable more than 10 years and one month from the date as of which
an option agreement is executed. These shares become vested through various
periods not to exceed four years from the date of grant. The option price
represents the fair market value of each underlying share of Common Stock at the

In December 1992, the Board of Directors approved the 1992 Stock Option
Plan (the 1992 Stock Option Plan) which provides for the grant of options to
purchase up to 92,160 shares of the Company's Common Stock to employees,
directors, and officers of the Company and to consultants, advisors, and other
persons whose contributions are important to the success of the Company. The
recipients of the options granted under the 1992 Stock Option Plan, the number
of shares to be covered by each option, and the exercise price, vesting terms,
if any, duration and other terms of each option shall be determined by the
Company's board of directors. No option is exercisable more than 10 years and
one month from the date as of which an option agreement is executed. To date, no
options have been granted under the 1992 Stock Option Plan.

The Company's 1993 Employee Stock Purchase Plan (the 1993 Purchase Plan)
was approved by the board of directors in July 1993. The outline of the 1993
Purchase Plan provides for the issuance, subject to adjustment for capital
changes, of an aggregate of 138,240 shares of Common Stock to employees.

The 1993 Purchase Plan is administered by the Compensation Committee of
the board of directors. Under the 1993 Purchase Plan, Company employees are
eligible to participate in semi-annual plan offerings in which payroll
deductions may be used to purchase shares of Common Stock. The purchase price
for such shares is equal to the lower of 85% of the fair market value of such
shares on the date of grant or 85% of its fair market value of such shares on
the date such right is exercised. There have been no offerings under the 1993
Purchase Plan to date and no shares of Common Stock have been issued thereunder.

During 2003, the Company issued options to acquire 200,000 shares to its
general counsel under the 1990 plan for services rendered. As a result, the
Company charged operating expenses in the amount of $237,000.

The Equity Incentive Plan effective May 1, 2004, authorizes the grant of
non-qualified and incentive stock options, stock appreciation rights, restricted
stock and other stock awards. A maximum of 8,000,000 shares of common stock is
reserved for potential issuance pursuant to awards under the Equity Incentive
Plan. Unless sooner terminated, the Equity Incentive Plan will continue in
effect for a period of 10 years from its effective date.

The Equity Incentive Plan is administered by the Board of Directors. The
Equity Incentive Plan provides for awards to be made to such officers, other key
employees, non-employee directors, consultants and advisors of the Company and
its subsidiaries as the Board may select.

F-40
Stock options  awarded under the Equity  Incentive Plan may be exercisable
at such times (not later than 10 years after the date of grant) and at such
exercise prices (not less than fair market value at the date of grant) as the
Board may determine. The Board may provide for options to become immediately
exercisable upon a "change in control," which is defined in the Equity Incentive
Plan to occur upon any of the following events: (a) the acquisition by any
person or group, as beneficial owner, of 20% or more of the outstanding shares
or the voting power of the outstanding securities of the Company; (b) either a
majority of the directors of Company at the annual stockholders meeting has been
nominated other than by or at the direction of the incumbent directors of the
Board, or the incumbent directors cease to constitute a majority of the
Company's Board; (c) the Company's stockholders approve a merger or other
business combination pursuant to which the outstanding common stock of the
Company no longer represents more than 50% of the combined entity after the
transaction; (d) the Company's shareholders approve a plan of complete
liquidation or an agreement for the sale or disposition of all or substantially
all of the Company's assets; or (e) any other event or circumstance determined
by the Company's Board to affect control of the Company and designated by
resolution of the Board as a change of control.

Information regarding the options approved by the Board of Directors under
the Equity Incentive Plan is summarized below:

entered into a standby finance agreement pursuant to which the parties agreed to
provide an aggregate of $5,500,000 in financing to the Company during 1995 in

warrants were issued leaving a balance of 5,436,189 at December 31, 2005.

(e) Stock Repurchase

The Company's repurchases of shares of common stock are recorded as
"Treasury Stock" and result in a reduction of "Stockholders' equity." When
treasury shares are reissued, the Company uses a first-in, first-out method and
the excess of repurchase cost over reissuance price is treated as a reduction of
"Additional paid-in capital." At December 31, 2003 there were 443 shares in the
treasury. During 2003 most of the then existing treasury shares were either
re-issued or retired. There was no Treasury Stock repurchased, re-issued and the
balance of 443 shares were sold in 2004.

(f) Rights offering

On November 19, 2002, the Board of Directors of Hemispherx Biopharma, Inc.
(the "Company") declared a dividend distribution of one Right for each
outstanding share of Common Stock to stockholders of record at the close of
business on November 29, 2002 (the "Record Date"). Each Right entitles the
registered holder to purchase from the Company a unit consisting of one
one-hundredth of a share (a "Unit") of Series A Junior Participating Preferred
Stock, par value $.01 per share (the "Series A Preferred Stock") at a Purchase
Price of $30.00 per Unit, subject to adjustment. The description and terms of
the Rights are set forth in a Rights Agreement (the "Rights Agreement") between
the Company and Continental Stock Transfer & Trust Company, as Rights Agent.

F-44
Initially,  the  Rights are  attached  to all  Common  Stock  certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. Subject to certain exceptions specified in the Rights Agreement,
the Rights will separate from the Common Stock and a Distribution Date will
occur upon the earlier of (i) 10 days following a public announcement that a
person or group of affiliated or associated persons (an "Acquiring Person") has
acquired beneficial ownership of 15% or more (or 20% or more for William A.
Carter, M.D.) of the outstanding shares of Common Stock (the "Stock Acquisition
Date"), other than as a result of repurchases of stock by the Company or certain
inadvertent actions by institutional or certain other stockholders or (ii) 10
business days (or such later date as the Board shall determine) following the
commencement of a tender offer or exchange offer that would result in a person
or group becoming an Acquiring Person. Until the Distribution Date, (i) the
Rights will be evidenced by the Common Stock certificates and will be
transferred with and only with such Common Stock certificates, (ii) new Common
Stock certificates issued after the Record Date will contain a notation
incorporating the Rights Agreement by reference and (iii) the surrender for
transfer of any certificates for Common Stock outstanding will also constitute
the transfer of the Rights associated with the Common Stock represented by such
certificate. Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the occurrence of a Triggering Event (as defined below) that,
upon any exercise of Rights, a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

(11) Research, Consulting and Supply Agreements

In 1994, the Company entered into a licensing agreement with Bioclones
(Proprietary) limited ("Bioclones") for manufacturing and international market
development in Africa, Australia, New Zealand, Tasmania, the United Kingdom,
Ireland and certain countries in South Africa, of Ampligen(R) and Oragen(TM).
The Company deemed this marketing arrangement with Bioclones void due to the
numerous and long standing failures of performance by Bioclones. On December 27,
2004 the Company initiated a lawsuit in Federal Court identifying a
conspiratorial group seeking to illegally manipulate the Company's stock for
purposes of bringing about a hostile takeover of Hemispherx. This conspiratorial
group includes Bioclones.

In 1998, the Company entered into a strategic alliance with Accredo to
develop certain marketing and distribution capacities for Ampligen(R) in the
United States. Accredo is one of the nation's largest home health care companies
with over 400 offices and sixty thousand caregivers nationwide. Pursuant to the
agreement, Accredo assumed certain responsibilities for distribution of
Ampligen(R) for which they received a fee. Through this arrangement, the Company
may mitigate the necessity of incurring certain up-front costs. Accredo has also
worked with the Company in connection with the Amp 511 ME/CFS cost recovery
treatment program, Amp 516 ME/CFS Phase III clinical trial and the Amp 719
(combining Ampligen(R) with other antiviral drugs in HIV-salvage therapy and Amp
720 HIV Phase IIb clinical trials now under way). There can be no assurances
that this alliance will develop a significant commercial position in any of its
targeted chronic disease markets. The agreement had an initial one year term
from February 9, 1998 with successive additional one year terms unless either
party notifies the other not less than 180 days prior to the anniversary date of
its intent to terminate the agreement. Also, the agreement may be terminated for
uncured defaults, or bankruptcy, or insolvency of either party and will
automatically terminate upon the Company's receiving an NDA for Ampligen(R) from
the FDA, at which time, a new agreement will need to be negotiated with Accredo
or another major drug distributor. There were no initial fees.

In December, 1999, the Company entered into an agreement with Biovail
Corporation International ("Biovail"). Biovail is an international full service
pharmaceutical company engaged in the formulation, clinical testing,
registration and manufacture of drug products utilizing advanced drug delivery
systems. Biovail is headquartered in Toronto, Canada. The agreement grants
Biovail the exclusive distributorship of the Company's product in the Canadian
territories subject to certain terms and conditions. In return, Biovail agrees
to conduct certain pre-marketing clinical studies and market development
programs, including without limitation, expansion of the Emergency Drug Release
Program in Canada with respect to the Company' products. Biovail agrees to work
with the Company in preparing and filing of a New Drug Submission with Canadian
Regulatory Authorities. Biovail invested $2.25 million in Hemispherx equity at
prices above the then current market price and agreed to make further payments
based on reaching certain regulatory milestones. The Agreement requires Biovail
to penetrate certain market segments at specific rates in order to maintain
market exclusivity. The agreement terminates on December 15, 2009, subject to
successive two-year extensions by the parties and subject to earlier termination
by the parties for uncured defaults under the agreement, bankruptcy or
insolvency of either party, or withdrawal of the Company's product from Canada
for a period of more than ninety days for serious adverse health or safety
reasons.

F-46
In May 2000, the Company acquired an interest in Chronix  Biomedical Corp.
("CHRONIX"). Chronix focuses upon the development of diagnostics for chronic
diseases. The Company issued 100,000 shares of common stock to Chronix toward a
total equity investment of $700,000. Pursuant to a strategic alliance agreement,
the Company provided Chronix with $250,000 to conduct research in an effort to
develop intellectual property on potential new products for diagnosing and
treating various chronic illnesses such as ME/CFS. The strategic alliance
agreement provides the Company certain royalty rights with respect to certain
diagnostic technology developed from this research and a right of first refusal
to license certain therapeutic technology developed from this research. The
strategic alliance agreement provides the Company with a royalty payment of 10%
of all net sales of diagnostic technology developed by Chronix for diagnosing
Chronic Fatigue Syndrome, Gulf War Syndrome and Human Herpes Virus-6 associated
diseases. The royalty continues for the longer of 12 years from September 15,
2000 or the life of any patent(s) issued with regard to the diagnostic
technology. The strategic alliance agreement also provides the Company with the
right of first refusal to acquire an exclusive worldwide license for any and all
therapeutic technology developed by Chronix on or before September 14, 2012 for
treating Chronic Fatigue Syndrome, Gulf War Syndrome and Human Herpes Virus-6
associated diseases. During the quarter ended December 31, 2002 and September
30, 2004 the Company recorded a noncash charge of $292,000 and $373,000,
respectively, with respect to the Company's investment in Chronix. This
impairment reduces the Company's carrying value to reflect a permanent decline
in Chronix's market value based on its then proposed equity offerings.

In March 2002, the Company's European subsidiary Hemispherx S.A. entered
into a Sales and Distribution agreement with Esteve. Pursuant to the terms of
the Agreement, Esteve was granted the exclusive right to market Ampligen(R) in
Spain, Portugal and Andorra for the treatment of ME/CFS. In addition to other
terms and other projected payments, Esteve agreed to conduct certain clinical
trials using Ampligen(R) in the patient population coinfected with HCV and HIV
viruses. The Agreement runs for the longer of ten years from the date of first
arms-length sale in the Territory, the expiration of the last Hemispherx patent
exploited by Esteve or the period of regulatory data protection for Ampligen(R)
in the applicable territory. Pursuant to the terms of the agreement Esteve is to
conduct clinical trials using Ampligen(R) to treat patients with both HCV and
HIV and is required to purchase certain minimum annual amounts of Ampligen(R)
following regulatory approval. Esteve initiated the HIV/HCV clinical trials in
Spain in late 2004, but did not proceed with the trials due to an inability to
enroll a sufficient number of patients. The Company is discussing with Esteve
their initiation of another clinical trial utilizing Ampligen(R) in another
indication. The agreement is terminable by either party if Ampligen(R) is
withdrawn from the territory for a specified period due to serious adverse
health or safety reasons; bankruptcy, insolvency or related issues of one of the
parties; or material breach of the agreement. Hemispherx may transform the
agreement into a non-exclusive agreement or terminate the agreement in the event
that Esteve does not meet specified percentages of its annual minimum purchase
requirements under the agreement. Esteve may terminate the agreement in the
event that Hemispherx fails to supply Ampligen(R) to the territory for a
specified period of time or certain clinical trials being conducted by
Hemispherx are not successful. The last patent with respect to this agreement
expires on June 5, 2012.

F-47
In October 2005, the Company signed a research agreement with the National
Institute of Infectious Diseases, in Tokyo, Japan. The collaboration, by Hideki
Hasegawa, M.D., Ph.D., Chief of the Laboratory of Infectious Disease Pathology,
will assess the Company's experimental therapeutic Ampligen(R) as a
co-administered immunotherapuetic to the Institution's nasal flu vaccine.

In October 2005, the Company also engaged the Sage Group, Inc., a health
care, technology oriented, strategy and transaction advisory firm, to assist the
Company in obtaining a strategic alliance in Japan for the use of Ampligen(R) in
treating Chronic Fatigue Syndrome or CFS (see Note 18). The Company is in
discussions with the Sage Group, Inc. to expand its engagement to assist the
Company in obtaining strategic alliance in Japan for the use of Ampligen(R) in
treating Avian Flu.

In November 2005, the Company entered into an agreement with Defence R&D
Canada, Suffield ("DRDC Suffield"), an agency of the Canadian Department of
National Defence, to evaluate the antiviral efficacy of the Company's
experimental therapeutic Ampligen(R) and Alferon(R) for protection against human
respiratory influenza virus infection in well validated animal models. DRDC
Suffield is conducting research and development of new drugs that could
potentially become part of the arsenal of existing antiviral weapons to combat
the bird flu. The initial study will focus on the testing of potential drugs
against the respiratory influenza virus infection on a mouse-adapted strain of
human influenza.

On December 9, 2005, the Company executed a Supply Agreement with
Hollister-Stier Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for
the contract manufacturing of Ampligen(R) for a five year term. Pursuant to the
agreement the Company will supply the key raw materials and Hollister-Stier will
formulate and bottle the Ampligen(R). In November 2005, the Company paid
$100,000 as a deposit in order to initiate the manufacturing project. This
deposit was expensed as research and development during the 4th Quarter 2005.
The achievement of the initial objectives described in the agreement, in
combination with the Company's polymer production facility under construction in
New Brunswick, N.J., may enable the Company to manufacture the raw materials for
approximately 10,000 doses of Ampligen(R) per week. The Company executed a
confidentiality agreement with Hollister-Stier; therefore, the Company commenced
the transfer of the Company's manufacturing technology to Hollister-Stier.
Currently, Hollister-Stier has completed two pilot manufacturing runs of
Ampligen(R) for stability testing.

On February 8, 2006, the Company executed a Manufacturing and Safety
Agreement with Hyaluron, Inc. ("Hyaluron") of Burlington, Massachusetts, for the
formulation, packaging and labeling of Alferon N Injection(R). Pursuant to the
Agreement, the Company will supply raw materials in sufficient quantity and
provide any pertinent information to the project.

The Company has entered into agreements for consulting services, which are
performed at medical research institutions and by medical and clinical research
individuals. The Company's obligation to fund these agreements can be terminated
after the initial funding period, which generally ranges from one to three years
or on an as-needed monthly basis. During the year ending December 31, 2003, 2004
and 2005 the Company incurred approximately $395,000, $220,000 and $236,000
respectively, of consulting service fees under these agreements. These costs are
charged to research and development expense as incurred.

(12)  401(K) Plan

The Company has a defined contribution plan, entitled the Hemispherx
Biopharma Employees 401(K) Plan and Trust Agreement (the 401(K) Plan). Full time
employees of the Company are eligible to participate in the 401(K) Plan
following one year of employment. Subject to certain limitations imposed by
federal tax laws, participants are eligible to contribute up to 15% of their
salary (including bonuses and/or commissions) per annum. Participants'
contributions to the 401(K) Plan may be matched by the Company at a rate
determined annually by the Board of Directors.

Each participant immediately vests in his or her deferred salary
contributions, while Company contributions will vest over one year. In 2003,
2004 and 2005 the Company provided matching contributions to each employee for
up to 6% of annual pay aggregating $34,000, $77,000 and $89,000 respectively.

(13) Royalties, License, and Employment Agreements

The Company also has entered into a licensing agreement with a group of
individuals and Hahnemann University relating to their contributions to the
development of certain compounds, including Ampligen(R), and to obtain exclusive
information and regulatory rights relating to these compounds. Under this
agreement, the Company will pay 2% of net sales proceeds of Ampligen(R) not to
exceed an aggregate amount of $6 million per year through 2005.

The Company acquired a series of patents on Oragens, potentially a set of
oral broad spectrum antivirals and immunological enhancers, through a licensing
agreement with Temple University in Philadelphia, PA. The Company was granted an
exclusive worldwide license from Temple for the Oragens products. These
compounds have been evaluated in various academic laboratories for application
to chronic viral and immunological disorders. The 2', 5' oligoadenylate
synthetase/RNase L system is an important and widely distributed pathway for the
inhibition of viral replication and tumor growth. The 2', 5' oligoadenylate
synthetase, up activation by double-stranded RNA, synthesizes 2', 5'
oligoadenylates (2-5A) from ATP. These bioactive 2-5As directly activate RNase
L, which degrades viral and cellular RNAs resulting in the inhibition of protein
synthesis. The bioactive 2-5A molecules can be degraded by various hydrolytic
enzymes, resulting in a short half life. Analogues of these bioactive 2-5As,
termed Oragen RNA compounds, have been produced to increase stability and
maintain or increase biological activity without demonstrable toxicity. Pursuant
to the terms of the Company's agreement with Temple, the Company is obligated to
pay royalties of 2% to 4% of sales depending on the amount of technical
assistance required. The Company currently pays a royalty of $30,000 per year to
Temple. This agreement is to remain in effect until the date that the last
licensed patent expires unless terminated sooner by mutual consent or default
due to royalties not being paid. The last Oragen(TM) patent expires on June 1,
2018. The Company records the payment of the royalty as research and development
cost for the period incurred.

In October 1994, the Company entered into a licensing agreement with
Bioclones (Propriety) Limited (SAB/Bioclones) with respect to co-development of
various RNA drugs, including Ampligen(R), for a period ending three years from
the expiration of the last licensed patents. The licensing agreement provided
SAB/Bioclones with an exclusive manufacturing and marketing license for certain
southern hemisphere countries (including certain countries in South America,
Africa and Australia as well as the United Kingdom and Ireland (the licensed
territory). We deem this marketing arrangement with Bioclones void due to the
numerous and long standing failures of performance by Bioclones.

F-49
In December  2004,  the Company  filed a  multicount  complaint in federal
court (Southern District of Florida) against a conspiratorial group, which
includes Bioclones, seeking to illegally manipulate the Company's stock for
purposes of bringing about a hostile takeover of Hemispherx (see Note 17).

In October 1994, the Board of Directors granted an at the time director of
the Company the right to receive 3% of gross proceeds of any licensing fees
received by the Company pursuant to the SAB/Bioclones licensing agreement, a fee
of .75% of gross proceeds in the event that SAB Bioclones makes a tender offer
for all or substantially all of the Company's assets, including a merger,
acquisition or related transaction, and a fee of 1% on all products manufactured
by SAB Bioclones.

On March 20, 2002, the Company's European subsidiary Hemispherx Biopharma
Europe, S.A. ("Hemispherx S.A.") entered into a sales and Distribution agreement
with Laboratories Del Dr. Esteve S.A. ("Esteve"). Pursuant to the terms of the
agreement, Esteve was granted the exclusive right to market Ampligen(R) in
Spain, Portugal and Andorra for the treatment of Myalgic/Chronic Fatigue
Syndrome ("ME/CFS"). In addition to other terms and other projected payments,
Esteve paid an initial and non-refundable fee of 625,000 Euros (approximately
$563,000) to Hemispherx S.A. on April 24, 2002. Esteve is to pay a fee of
1,000,000 Euros after U.S. Food and Drug Administration approval of Ampligen(R)
for the treatment of ME/CFS and a fee of 1,000,000 Euros upon Spain's approval
of the final marketing authorization for using Ampligen(R) for the treatment of
ME/CFS.

In connection with the two agreements entered into with ISI, the Company
is obligated to pay ISI a 6% royalty on the net sales of the Alferon N
Injection(R) product.

The Company has contractual agreements with two of its officers. The
aggregate annual base compensation under these contractual agreements for 2003,
2004 and 2005 was $637,000, $662,000 and $701,000 respectively. In addition,
certain of these officers are entitled to receive performance bonuses of up to
25% of the annual base salary (in addition to the bonuses described below). In
2003, 2004 and 2005, bonuses of $266,100, 264,800 and $175,300 respectively were
granted. In 2003, the Chief Executive Officer of the Company was granted
warrants to purchase 1,450,000 shares of common stock at $2.20 per share. The
Chief Executive Officer's employment agreement (see below) provides for bonuses
based on gross proceeds received by the Company from any joint venture or
corporate partnering agreement. In 2004, the Chief Executive Officer of the
Company was granted options to purchase 320,000 shares of common stock at $2.60
per share and $3.44 per share and the Chief Financial Officer of the Company was
granted options to purchase 63,824 shares of common stock at $2.60 and $3.44 per
share. In 2005, the Chief Executive Officer of the Company was granted options
to purchase 945,000 shares of common stock at $1.75 to $2.87 per share and the
Chief Financial Officer of the Company was granted options to purchase 110,000
shares of common stock at $1.75 to $2.61 per share.

F-50
On March 11, 2005, the Company's board of directors, at the recommendation
of the Compensation Committee, approved an amended and restated employment
agreement and an amended and restated engagement agreement with Dr. William A.
Carter.

The amended and restated employment agreement provides for Dr. Carter's
employment as the Company's Chief Executive Officer and Chief Scientific Officer
until December 31, 2010 unless sooner terminated for cause or disability. The
agreement automatically renews for successive one year periods after the initial
termination date unless the Company or Dr. Carter give written notice otherwise
at least ninety days prior to the termination date or any renewal period. Dr.
Carter has the right to terminate the agreement on 30 days' prior written
notice. The initial base salary retroactive to January 1, 2005 is $290,888,
subject to adjustment based on the average increase or decrease in the Consumer
Price Index for the prior year. In addition, Dr. Carter could receive an annual
performance bonus of up to 25% of his base salary, at the sole discretion of the
Compensation Committee of the board of directors, based on his performance or
the Company's operating results. Dr. Carter will not participate in any
discussions concerning the determination of his annual bonus. Dr. Carter is also
entitled to an incentive bonus of 0.5% of the gross proceeds received by us from
any joint venture or corporate partnering arrangement. Dr. Carter's agreement
also provides that he be paid a base salary and benefits through the last day of
the then term of the agreement if he is terminated without "cause", as that term
is defined in agreement. In addition, should Dr. Carter terminate the agreement
or the agreement be terminated due to his death or disability, the agreement
provides that Dr Carter be paid a base salary and benefits through the last day
of the month in which the termination occurred and for an additional twelve
month period. Pursuant to his original agreement, Dr. Carter was granted options
to purchase 73,728 (post split) shares in 1991. The exercise period of these
options is extended through December 31, 2010 and, should Dr. Carter's
employment agreement be extended beyond that date, the option exercise period is
further extended to the last day of the extended employment period.

The amended and restated engagement agreement, retroactive to January 1,
2005, provides for the Company's engagement of Dr. Carter as a consultant
related to patent development, as one of the Company's directors and as chairman
of the Executive Committee of the Company's board of directors until December
31, 2010 unless sooner terminated for cause or disability. The agreement
automatically renews for successive one year periods after the initial
termination date or any renewal period. Dr. Carter has the right to terminate
the agreement on 30 days' prior written notice. The initial base fee as of
January 1, 2004 is $207,777, subject to annual adjustments equal to the
percentage increase or decrease of annual dollar value of directors' fees
provided to the Company's directors during the prior year. The annual fee is
further subject to adjustment based on the average increase or decrease in the
Consumer Price Index for the prior year. In addition, Dr. Carter could receive
an annual performance bonus of up to 25% of his base fee, at the sole direction
of the Compensation Committee of the board of directors, based on his
performance. Dr. Carter will not participate in any discussions concerning the
determination of this annual bonus. Dr. Carter's agreement also provides that he
be paid his base fee through the last day of the then term of the agreement if
he is terminated without "cause", as that term is defined in the agreement. In
addition, should Dr. Carter terminate the agreement or the agreement be
terminated due to his death or disability, the agreement provides that Dr.
Carter be paid fees due him through the last day of the month in which the
termination occurred and for an additional twelve month period.

F-51
On February 14, 2005 the Company  entered into an agreement  with The Sage
Group of Branchburg, New Jersey for R. Douglas Hulse, an Executive Director of
The Sage Group, to serve as President and Chief Operating Officer of the
Company. In addition, other Sage Group principals and Senior Directors will be
made available to assist as needed. The engagement is expected to continue for a
period of 18 months; however, it is terminable on 30 days written notice by
either party after 12 months. Compensation for the services include a ten year
warrant to purchase 250,000 shares of the Company's common stock at an exercise
price of $1.55. These warrants are to be issued to Sage Healthcare Advisors, LLC
and are to vest at the rate of 12,500 per month of the engagement with 25,000
vesting upon completion of the eighteenth month. Vesting accelerates in the
event of a merger or a purchase of a majority of the Company's assets or equity.
The Sage Group also is to receive a monthly retainer of $10,000 for the period
of the engagement. In addition, for each calendar year (or part thereof) during
which the agreement is in effect, The Sage Group will be entitled to an
incentive bonus in an amount equal to 0.5% of the gross proceeds received by us
during such year from any joint ventures or corporate partnering arrangements.
After termination of the agreement, The Sage Group will only be entitled to
receive the incentive bonus based upon gross proceeds received by us during the
two year period commencing on the termination of the agreement with respect to
any joint ventures or corporate partnering arrangements entered into by us
during the term of the agreement. Mr. Hulse will devote approximately two to two
and one half days per week to the Company's business.

The Company entered into an engagement agreement, retroactive to January
1, 2005, with Ransom W. Etheridge which provides for Mr. Etheridge's engagement
as the Company's General Counsel until December 31, 2009 unless sooner

F-52
On March 11, 2005 the Board of Directors, deeming it essential to the best
interests of the Company's shareholders to foster the continuous engagement of
key management personnel and recognizing that, as is the case with many publicly
held corporations, a change of control might occur and that such possibility,
and the uncertainty and questions which it might raise among management, might
result in the departure or distraction of management personnel to the detriment
of the Company and the Company's shareholders, determined to reinforce and
encourage the continued attention and dedication of members of the Company's
management to their engagement without distraction in the face of potentially
disturbing circumstances arising from the possibility of a change in control of
the Company and entered into identical agreements regarding change in control
with William A. Carter, the Company's Chief Executive Officer and Chief
Scientific Officer, Robert E. Peterson, the Company's Chief Financial Officer
and Ransom W. Etheridge, the Company's General Counsel. Each of the agreements
regarding change in control became effective March 11, 2005 and continue through
December 31, 2007 and shall extend automatically to the third anniversary
thereof unless the Company gave notice to the other party prior to the date of
such extension that the agreement term will not be extended. Notwithstanding the
foregoing, if a change in control occurs during the term of the agreements, the
term of the agreements will continue through the second anniversary of the date
on which the change in control occurred. Each of the agreements entitles William
A. Carter, Robert E. Peterson and Ransom W. Etheridge, respectively, to change
of control benefits, as defined in the agreements and summarized below, upon
their respective termination of employment/engagement with the Company during a
potential change in control, as defined in the agreements or after a change in
control, as defined in the agreements, when their respective terminations are
caused (1) by us for any reason other than permanent disability or cause, as
defined in the agreement (2) by William A. Carter, Robert E. Peterson and/or
Ransom W. Etheridge, respectively, for good reason as defined in the agreement
or, (3) by William A. Carter, Robert E. Peterson and/or Ransom W. Etheridge,
respectively for any reason during the 30 day period commencing on the first
date which is six months after the date of the change in control.

The benefits for each of the foregoing executives would be as follows:

o A lump sum cash payment of three times his base salary and annual
bonus amounts; and
o Outplacement benefits.

Each agreement also provides that the executive is entitled to a "gross-up"
payment to make him whole for any federal excise tax imposed on change of
control or severance payments received by him. Dr. Carter's agreement also
provides for the following benefits:

o Continued insurance coverage through the third anniversary of his
termination; and

F-53
o     Retirement  benefits computed as if he had continued to work for the
above period.

In order to facilitate the Company's need to obtain financing and prior to
the Company's shareholders approving an amendment to the Company's corporate
charter to merge the number of authorized shares, Dr. Carter, the Company's
Chief Executive Officer, agreed to waive his right to exercise certain warrants
and options unless and until the Company's shareholder approved an increase in
the Company's authorized shares of Common Stock.

In October 2003, in recognition of this action as well as Dr. Carter's
prior and on-going efforts relating to product development securing critically
needed financing and the acquisition of a new product line, the Compensation
Committee determined that Dr. Carter be awarded bonus compensation in 2003
consisting of $196,636 and a grant of 1,450,000 stock warrants for a value of
$1,769,000 based on Black Scholes calculations with an exercise price of $2.20
per share. This additional compensation was reviewed by an independent valuation
firm and found to be fair and reasonable within the context of total
compensation paid to chief executive officers of comparable biotechnology
companies. These warrants vested upon the second ISI Asset closing. The Company
expensed the intrinsic value of these warrants upon their vesting.

The Company has engaged the Sage Group, Inc., a health care, technology
oriented, strategy and transaction advisory firm, to assist us in obtaining a
strategic alliance in Japan for the use of Ampligen(R) in treating Chronic
Fatigue Syndrome or CFS. R. Douglas Hulse, the Company's President and Chief
Operating Officer, is a member and an executive director of The Sage Group, Inc.

respectively. The term of the lease for the Rockville, Maryland facility expired
June 2005. The Company transferred this operational site to the Company's New
Jersey facility. The term of the lease for the Philadelphia, Pennsylvania
offices is through April, 2007 with an average rent of $15,000 per month, plus
applicable taxes and charges.

(15)  Income Taxes

As of December 31, 2005, the Company has approximately $81,000,000 of
federal net operating loss carryforwards (expiring in the years 2006 through
2026) available to offset future federal taxable income. The Company also has
approximately $28,000,000 of state net operating loss carryforwards (expiring in
the years 2006 through 2010) available to offset future state taxable income.
The utilization of certain state net operating loss carryforwards may be subject
to annual limitations.

Under the Tax Reform Act of 1986, the utilization of a corporation's net
operating loss carryforward is limited following a greater than 50% change in
ownership. Due to the Company's prior and current equity transactions, the
Company's net operating loss carryforwards may be subject to an annual
limitation generally determined by multiplying the value of the Company on the
date of the ownership change by the federal long-term tax exempt rate. Any
unused annual limitation may be carried forward to future years for the balance
of the net operating loss carryforward period.

Deferred income taxes reflect the net tax effects of temporary differences
between carrying amounts of assets and liabilities for financial reporting
purposes and the carrying amounts used for income tax purposes. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which temporary
differences representing net future deductible amounts become deductible. Due to
the uncertainty of the Company's ability to realize the benefit of the deferred
tax asset, the deferred tax assets are fully offset by a valuation allowance at
December 31, 2004 and 2005.


The components of the net deferred tax asset of December 31, 2004 and 2005
consists of the following:

(16) Contingencies

On September 30, 1998, the Company filed a multi-count complaint against
Manuel P. Asensio, Asensio & Company, Inc. ("Asensio"). The action included
claims of defamation, disparagement, tortuous interference with existing and
prospective business relations and conspiracy, arising out of Asensio's false
and defamatory statements. The complaint further alleged that Asensio defamed
and disparaged the Company in furtherance of a manipulative, deceptive and
unlawful short-selling scheme in August and September, 1998. In 1999, Asensio
filed an answer and counterclaim alleging that in response to Asensio's strong
sell recommendation and other press releases, the Company made defamatory
statements about Asensio. The Company denied the material allegations of the
counterclaim. In July 2000, following dismissal in federal court for lack of
subject matter jurisdiction, the Company transferred the action to the
Pennsylvania State Court. In March 2001, the defendants responded to the
complaints as amended and a trial commenced on January 30, 2002. A jury verdict
disallowed the claims against the defendants for defamation and disparagement
and the court granted the Company a directed verdict on the counterclaim. On
July 2, 2002 the Court entered an order granting the Company a new trial against
Asensio for defamation and disparagement. Thereafter, Asensio appealed the
granting of a new trial to the Superior Court of Pennsylvania. The Superior
Court of Pennsylvania has denied Asensio's appeal. Asensio petitioned the
Supreme Court of Pennsylvania for allowance of an appeal, which was denied. The
Company now anticipates the scheduling of a new trial against Asensio for
defamation and disparagement in the Philadelphia Common Pleas Court.

In June 2002, a former ME/CFS clinical trial patient and her husband filed
a claim in the Superior Court of New Jersey, Middlesex County, against the
Company, one of its clinical trial investigators and others alleging that she
was harmed in the ME/CFS clinical trial as a result of negligence and breach of
warranties. On June 25, 2004 all claims against the Company were dismissed with
prejudice. The former ME/CFS clinical trial patient and her husband have now
appealed the dismissal of their claims to the New Jersey Superior Court,
Apellate Division, upheld the dismissal of all claims against the Company and
the matter is now concluded.

In June 2002, a former ME/CFS clinical trial patient in Belgium filed a
claim in Belgium, against Hemispherx Biopharma Europe, NV/SA, the Company's
Belgian subsidiary, and one of the Company's clinical trial investigators
alleging that she was harmed in the Belgium ME/CFS clinical trial as a result of
negligence and breach of warranties. The Company believes the claim is without
merit and the Company is defending the claim against the Company through its
product liability insurance carrier.

In December 2004, the Company filed a multicount complaint in federal
court (Southern District of Florida) against a conspiratorial group, which
includes Bioclones, seeking to illegally manipulate its stock for purposes of
bringing about a hostile takeover of Hemispherx. The lawsuit alleges that the
conspiratorial group commenced with a plan to seize control of its cash and
proprietary assets by an illegal campaign to drive down its stock price and
publish disparaging reports on the Company's management and current fiduciaries.
The lawsuit seeks monetary damages from each member of the conspiratorial group
as well as injunctions preventing further recurrences of their misconduct. The
conspiratorial group includes Bioclones, a privately held South African
Biopharmaceutical company that collaborated with the Company (see Note 13), and
Johannesburg Consolidated Investments, a South African corporation, Cyril
Donninger, R. B. Kebble, H. C. Buitendag, Bart Goemaere, and John Doe(s).
Bioclones, Johannesburg Consolidated Investments, Cyril Donninger, R. B. Kebble
and H.C. Buitendag filed a motion to dismiss the complaint, which was granted by
the court. The Company is in the process of appealing this decision to the 11th
federal circuit court of appeals.

F-56
On January 10, 2005,  the Company  initiated a  multicount  lawsuit in the
United States District Court for the Eastern District of Pennsylvania seeking
injunctive relief and damages against a conspiratorial group, many of whom are
foreign nationals or companies located outside the United States alleging that
the conspiratorial group has engaged in secret meetings, market manipulations,
fraudulent misrepresentations, utilization of foreign accounts and foreign
secrecy laws all in furtherance of an illegal scheme to take over Hemispherx and
enrich themselves at the expense of Hemispherx's public shareholders. On
February 18, 2005 the Company filed an amended complaint in the same lawsuit
joining Redlabs, USA, Inc. as a defendant with the existing defendants R.E.D.
Laboratories, N.V./S.A., Bart Goemaere, Jan Goemaere, Dr. Kenny De Meirleir,
Kenneth Schepmans, Johan Goossens, Lieven Vansacker and John Does. Pursuant to
an agreement in which R.E.D. Laboratories, N.V./S.A. and Dr. Kenny DeMeirleir
agreed not to participate in a hostile takeover of Hemispherx for a period of
five years, R.E.D. Laboratories, N.V./S.A. and Dr. Kenny DeMeirleir have been
dismissed as defendants in the litigation. The litigation is proceeding against
the remaining defendants.

(17) Certain Relationships and Related Transactions

The Company has employment agreements with certain of its executive
officers and have granted such officers and directors options and warrants to
purchase its common stock, as discussed in Notes 3(n) and 13.

Ransom W. Etheridge, the Company's Secretary, General Counsel and one of
its directors, is an attorney in private practice, who renders corporate legal
services to us from time to time, for which he has received fees totaling

engagement. In addition, for each calendar year (or part thereof) during which
the agreement is in effect, Sage Group will be entitled to an incentive bonus in
an amount equal to 0.5% of the gross proceeds received by the Company during
such year from any joint ventures or corporate partnering arrangements. After
termination of the agreement, Sage Group will only be entitled to receive the
incentive bonus based upon gross proceeds received by the Company during the two
year period commencing on the termination of the agreement with respect to any
