General

Heartland Express, Inc. ("Heartland" or the "Company") is a short-to-medium
haul truckload carrier based near Iowa City, Iowa. The Company provides
nationwide transportation service to major shippers, using late-model equipment
and a combined fleet of company-owned and owner-operator tractors. The Company's
primary traffic lanes are between customer locations east of the Rocky
Mountains. In the second quarter of 2005, the Company expanded to the Western
United States with the opening of a terminal in Phoenix, Arizona. Management
believes that the Company's service standards and equipment accessibility have
made it a core carrier to many of its major customers.

Heartland was founded by Russell A. Gerdin in 1978 and became publicly
traded in November 1986. Over the twenty years from 1986 to 2006, Heartland has
grown to $571.9 million in revenue from $21.6 million and net income has
increased to $87.2 million from $3.0 million. Much of this growth has been
attributable to expanding service for existing customers, acquiring new
customers, and continued expansion of the Company's operating regions. More
information regarding the Company's revenues, profits, and assets for the past
three years can be found in our "Consolidated Balance Sheets" and "Consolidated
Statements of Income" that are included in this report.

In addition to internal growth, Heartland has completed five acquisitions
since 1987 with the most recent in 2002. In June 2002, the Company purchased the
business and trucking assets of Chester, Virginia based truckload carrier Great
Coastal Express. These five acquisitions have enabled Heartland to solidify its
position within existing regions, expand into new operating regions, and to
pursue new customer relationships in new markets. The Company will continue to
evaluate acquisition candidates that meet its financial and operating
objectives.

Heartland Express, Inc. is a holding company incorporated in Nevada, which
owns all of the stock of Heartland Express Inc. of Iowa, Heartland Equipment,
Inc., and A & M Express, Inc. The Company operates as one reportable operating
segment.

Operations

Heartland's operations department focuses on the successful execution of
customer expectations and providing consistent opportunity for the fleet of
employee drivers and independent contractors, while maximizing equipment
utilization. These objectives require a combined effort of marketing, regional
operations managers, and fleet management.

The Company's operations department is responsible for maintaining the
continuity between the customer's needs and Heartland's ability to meet those
needs by communicating customer's expectations to the fleet management group.
They are charged with development of customer relationships, ensuring service
standards, coordinating proper freight-to-capacity balancing, trailer asset
management, and daily tactical decisions pertaining to matching the customer
demand with the appropriate capacity within geographical service areas. They
assign orders to drivers based on well-defined criteria, such as driver safety
and United States Department of Transportation (the "DOT") compliance, customer
needs and service requirements, equipment utilization, driver time at home,
operational efficiency, and equipment maintenance needs.

1
Fleet  management  employees  are  responsible  for driver  management  and
development. Additionally, they maximize the capacity that is available to the
organization to meet the service needs of the Company's customers. Their
responsibilities include meeting the needs of the drivers within the standards
that have been set by the organization and communicating the requirements of the
customers to the drivers on each order to ensure successful execution.

Serving the short-to-medium haul market (518-mile average length of haul in
2006) permits the Company to use primarily single, rather than team drivers and
dispatch most loads directly from origin to destination without an intermediate
equipment change other than for driver scheduling purposes.

Heartland also operates eight specialized regional distribution operations
in Atlanta, Georgia; Carlisle, Pennsylvania; Columbus, Ohio; Jacksonville,
Florida; Kingsport, Tennessee; Chester, Virginia; Olive Branch, Mississippi; and
Phoenix, Arizona. These short-haul operations concentrate on freight movements
generally within a 400-mile radius of the regional terminal and are designed to
meet the needs of significant customers in those regions.

Personnel at the regional locations manage these operations, and the
Company uses a centralized computer network and regular communication to achieve
company-wide load coordination.

The Company emphasizes customer satisfaction through on-time performance,
dependable late-model equipment, and consistent equipment availability to meet
the volume requirements of its large customers. The Company also maintains a
high trailer to tractor ratio, which facilitates the positioning of trailers at
customer locations for convenient loading and unloading. This minimizes waiting
time, which increases tractor utilization and promotes driver retention.

Customers and Marketing

The Company targets customers in its operating area with multiple,
time-sensitive shipments, including those utilizing "just-in-time" manufacturing
and inventory management. In seeking these customers, Heartland has positioned
itself as a provider of premium service at compensatory rates, rather than
competing solely on the basis of price. Freight transported for the most part is
non-perishable and predominantly does not require driver handling. We believe
Heartland's reputation for quality service, reliable equipment, and equipment
availability makes it a core carrier for many of its customers.

Heartland seeks to transport freight that will complement traffic in its
existing service areas and remain consistent with the Company's focus on
short-to-medium haul and regional distribution markets. Management believes that
building lane density in the Company's primary traffic lanes will minimize empty
miles and enhance driver "home time."

The Company's 25, 10, and 5 largest customers accounted for 68%, 49%, and
35% of revenue, respectively, in 2006. The Company's primary customers include
retailers and manufacturers. The distribution of customers is not significantly
different from the previous year. One customer accounted for 14% of revenue in
2006. No other customer accounted for as much as ten percent of revenue.

Seasonality

The nature of the Company's primary traffic (appliances, automotive parts,
consumer products, paper products, packaged foodstuffs, and retail goods) causes
it to be distributed with relative uniformity throughout the year. However,
seasonal variations during and after the winter holiday season have historically
resulted in reduced shipments by several industries. In addition, the Company's
operating expenses historically have been higher during the winter months due to
increased operating costs and higher fuel consumption in colder weather.

Drivers, Independent Contractors, and Other Employees

Heartland relies on its workforce in achieving its business objectives. As
of December 31, 2006, Heartland employed 3,317 persons. The Company also
contracted with independent contractors to provide and operate tractors.
Independent contractors own their own tractors and are responsible for all
associated expenses, including financing costs, fuel, maintenance, insurance,
and highway use taxes. The Company historically has operated a combined fleet of
company and independent contractor tractors.

2
Management's strategy for both employee drivers and independent contractors
is to (1) hire only safe and experienced drivers; (2) promote retention with an
industry leading compensation package, positive working conditions, and
targeting freight that requires little or no handling; and (3) minimize safety
problems through careful screening, mandatory drug testing, continuous training,
and financial rewards for accident-free driving. Heartland also seeks to
minimize turnover of its employee drivers by providing modern, comfortable
equipment, and by regularly scheduling them to their homes. All drivers are
generally compensated on the basis of miles driven including empty miles. This
provides an incentive for the Company to minimize empty miles and at the same
time does not penalize drivers for inefficiencies of operations that are beyond
their control.

Heartland is not a party to a collective bargaining agreement. Management
believes that the Company has good relationships with its employees.

Revenue Equipment

Heartland's management believes that operating high-quality, efficient
equipment is an important part of providing excellent service to customers. All
tractors are equipped with satellite-based mobile communication systems. This
technology allows for efficient communication with our drivers to accommodate
the needs of our customers. A uniform fleet of tractors and trailers are
utilized to minimize maintenance costs and to standardize the Company's
maintenance program. In June, 2004 the Company began the replacement of its
entire tractor fleet with trucks manufactured by Navistar International
Corporation. At December 31, 2006, primarily all the Company's tractors are
manufactured by Navistar International Corporation. Primarily all of the
Company's trailers are manufactured by Wabash National Corporation. The
Company's policy is to operate its tractors while under warranty to minimize
repair and maintenance cost and reduce service interruptions caused by
breakdowns. In addition, the Company's preventive maintenance program is
designed to minimize equipment downtime, facilitate customer service, and
enhance trade value when equipment is replaced. Factors considered when
purchasing new equipment include fuel economy, price, technology, warranty
terms, manufacturer support, driver comfort, and resale value. Owner-operator
tractors are periodically inspected by the Company for compliance with
operational and safety requirements of the Company and the DOT.

Effective October 1, 2002, the Environmental Protection Agency (the "EPA")
implemented engine requirements designed to reduce emissions. These new emission
standards have resulted in a significant increase in the cost of new tractors,
lower fuel efficiency, and higher maintenance costs. The EPA has mandated
additional engine emissions requirements that will take effect in January 2007.
Compliance with the 2007 standards is expected to further increase the cost of
new tractors, decrease fuel economy, and increase maintenance costs. The
inability to recover these cost increases with rate increases or cost reduction
efforts could adversely affect the Company's results of operations.

Fuel

The Company purchases fuel through a network of approximately 28 fuel stops
throughout the United States at which the Company has negotiated price
discounts. Bulk fuel sites are maintained at ten of the Company's terminal
locations in order to take advantage of volume pricing. Both aboveground and
underground storage tanks are utilized at the bulk fuel sites. Exposure to
environmental clean up costs is minimized by periodic inspection and monitoring
of the tanks.

Increases in fuel prices can have an adverse effect on the results of
operations. The Company has fuel surcharge agreements with most customers
enabling the pass through of long-term price increases. Fuel consumed by empty
and out-of-route miles and by truck engine idling time is not recoverable.

Competition

The truckload industry is highly competitive and fragmented with thousands
of carriers of varying sizes. The Company competes with other truckload
carriers; primarily those serving the regional, short-to-medium haul market.
Logistics providers, railroads, less-than-truckload carriers, and private fleets
provide additional competition but to a lesser extent. The industry is highly
competitive based primarily upon freight rates, service, and equipment
availability. The Company competes effectively by providing high-quality service
and meeting the equipment needs of targeted shippers. In addition, there is a
strong competition within the industry for hiring of drivers and independent
contractors.


3
Safety and Risk Management

We are committed to promoting and maintaining a safe operation. Our safety
program is designed to minimize accidents and to conduct our business within
governmental safety regulations. The Company hires only safe and experienced
drivers. We communicate safety issues with drivers on a regular basis and
emphasize safety through equipment specifications and regularly scheduled
maintenance intervals. Our drivers are compensated and recognized for the
achievement of a safe driving record.

The primary risks associated with our business include cargo loss and
physical damage, personal injury, property damage, and workers' compensation
claims. The Company self-insures a portion of the exposure related to all of the
aforementioned risks. Insurance coverage including, self-insurance retention
levels, is evaluated on an annual basis. The Company actively participates in
the settlement of each claim incurred.

The Company self-insures auto liability (personal injury and property
damage) claims up to $1.0 million per occurrence. In addition, the Company is
responsible for the first $2.0 million in the aggregate for all claims in excess
of $1.0 million and below $2.0 million. Liabilities in excess of these amounts
and up to $50.0 million per occurrence are assumed by an insurance company. The
Company assumes any liability in excess of $50.0 million. Catastrophic physical
damage coverage is carried to protect against natural disasters. The Company
self-insures workers' compensation claims up to $1.0 million per occurrence. The
Company increased the retention amount from $500,000 to $1.0 million effective
April 1, 2005. All amounts in excess of $1.0 million are covered by an insurance
company. In addition, primary and excess coverage is maintained for employee
medical and hospitalization expenses.

Regulation

The Company is a common and contract motor carrier regulated by the DOT and
various state and local agencies. The DOT generally governs matters such as
safety requirements, registration to engage in motor carrier operations,
insurance requirements, and periodic financial reporting. The Company currently
has a satisfactory DOT safety rating, which is the highest available rating. A
conditional or unsatisfactory DOT safety rating could have an adverse effect on
the Company, as some of the Company's contracts with customers require a
satisfactory rating. Such matters as weight and dimensions of equipment are also
subject to federal, state, and international regulations.

The Federal Motor Carrier Safety Administration (the "FMCSA") of the U.S.
Department of Transportation issued a final rule on April 24, 2003, that made
several changes to the regulations governing the hours of service for drivers of
commercial vehicles that deliver freight. The new rules became effective on
January 4, 2004. On July 16, 2004, the U.S. Circuit Court of Appeals for the
District of Columbia rejected the new hours of service rules for truck drivers,
contending that the FMCSA had failed to properly address the impact of the rules
on the health of drivers as required by Congress. On September 30, 2004, the
extension of the federal highway bill signed into law by the President extended
the previously vacated 2003 hours of service rules until the FMCSA could adopt a
new set of regulations, but not later than September 30, 2005. Effective October
1, 2005, all truckload carriers became subject to revised hours of service
regulations. The only significant change from the previous regulations is that a
driver using the sleeper berth provision must take at least eight consecutive
hours in the sleeper berth during their ten hours off-duty. Previously, drivers
were allowed to split their ten hour off-duty time in the sleeper berth into two
periods, provided neither period was less than two hours. This more restrictive
sleeper berth provision is requiring some drivers to more efficiently plan their
schedules and may have a negative impact on mileage productivity. It is expected
that the greatest impact will be for multiple-stop shipments or those shipments
with pickup or delivery delays. Multiple-stop shipments are an insignificant
portion of the Company's business. The Company has avoided a significant
disruption in productivity through proper planning and customer communications
in an effort to more efficiently schedule driver loading and unloading of
freight.

We also may become subject to new or more restrictive regulations relating
to matters such as fuel emissions and ergonomics. Our company drivers and
independent contractors also must comply with the safety and fitness regulations
promulgated by the DOT, including those relating to drug and alcohol testing.
Additional changes in the laws and regulations governing our industry could
affect the economics of the industry by requiring changes in operating practices
or by influencing the demand for, and the costs of providing, services to
shippers.

The Company's operations are subject to various federal, state, and local
environmental laws and regulations, implemented principally by the EPA and
similar state regulatory agencies. These laws and regulations include the
management of underground fuel storage tanks, the transportation of hazardous
materials, the discharge of pollutants into the air and surface and underground
waters, and the disposal of hazardous waste.


4
The  Company  transports  an
insignificant number of hazardous material shipments. Management believes that
its operations are in compliance with current laws and regulations and does not
know of any existing condition that would cause compliance with applicable
environmental regulations to have a material effect on the Company's capital
expenditures, earnings and competitive position. In the event the Company should
fail to comply with applicable regulations, the Company could be subject to
substantial fines or penalties and to civil or criminal liability.

ITEM 1A. RISK FACTORS

Our future results may be affected by a number of factors over which we
have little or no control. The following issues, uncertainties, and risks, among
others, should be considered in evaluating our business and growth outlook.

Our business is subject to general economic and business factors that are
largely out of our control.

Our business is dependent on a number of factors that may have a materially
adverse effect on our results of operations, many of which are beyond our
control. The most significant of these factors are recessionary economic cycles,
changes in customers' inventory levels, excess tractor or trailer capacity in
comparison with shipping demand, and downturns in customers' business cycles.
Economic conditions, particularly in market segments and industries where we
have a significant concentration of customers and in regions of the country
where we have a significant amount of business, that decrease shipping demand or
increase the supply of tractors and trailers can exert downward pressure on
rates or equipment utilization, thereby decreasing asset productivity. Adverse
economic conditions also may harm our customers and their ability to pay for our
services. Customers encountering adverse economic conditions represent a greater
potential for loss, and we may be required to increase our allowance for
doubtful accounts.

We are also subject to increases in costs that are outside of our control
that could materially reduce our profitability if we are unable to increase our
rates sufficiently. Such cost increases include, but are not limited to,
declines in the resale value of used equipment, increases in interest rates,
fuel prices, taxes, tolls, license and registration fees, insurance, revenue
equipment, and healthcare for our employees. We could be affected by strikes or
other work stoppages at customer, port, border, or other shipping locations.

In addition, we cannot predict the effects on the economy or consumer
confidence of actual or threatened armed conflicts or terrorist attacks, efforts
to combat terrorism, military action against a foreign state or group located in
a foreign state, or heightened security requirements. Enhanced security measures
could impair our operating efficiency and productivity and result in higher
operating costs.

Our growth may not continue at historic rates.

Historically, we have experienced significant and rapid growth in revenue
and profits. There can be no assurance that our business will continue to grow
in a similar fashion in the future or that we can effectively adapt our
management, administrative, and operational systems to respond to any future
growth. Further, there can be no assurance that our operating margins will not
be adversely affected by future changes in and expansion of our business or by
changes in economic conditions.

5
Increased  prices,  reduced  productivity,  and restricted  availability  of new
revenue equipment may adversely affect our earnings and cash flows.

We have experienced higher prices for new tractors over the past few years,
partially as a result of government regulations applicable to newly manufactured
tractors and diesel engines, in addition to higher commodity prices and better
pricing power among equipment manufacturers. More restrictive Environmental
Protection Agency, or EPA, emissions standards for 2007 will require vendors to
introduce new engines. Additional EPA mandated emission standards will become
effective for newly manufactured trucks beginning in January 2010. We have
decided to upgrade our fleet with pre-2007 engines. Our business could be harmed
if we are unable to continue to obtain an adequate supply of new tractors and
trailers. We expect to continue to pay increased prices for equipment.
Furthermore, when we do decide to purchase tractors with post-2007 engines, such
engines are expected to reduce equipment productivity and lower fuel mileage
and, therefore, increase our operating expenses. At December 31, 2006, 100% of
our tractor fleet was comprised of tractors with pre-2007 engines that meet
EPA-mandated clean air standards.

In addition, a decreased demand for used revenue equipment could adversely
affect our business and operating results. We rely on the sale and trade-in of
used revenue equipment to offset the cost of new revenue equipment. The demand
for used revenue equipment is currently stable. However, a reversal of this
trend could result in lower market values. This would increase our capital
expenditures for new revenue equipment, decrease our gains on sale of revenue
equipment, or increase our maintenance costs if management decides to extend the
use of revenue equipment in a depressed market.

If fuel prices increase significantly, our results of operations could be
adversely affected.

We are subject to risk with respect to purchases of fuel. Prices and
availability of petroleum products are subject to political, economic, and
market factors that are generally outside our control. Political events in the
Middle East, Venezuela, and elsewhere and hurricanes, and other weather-related
events, also may cause the price of fuel to increase. Because our operations are
dependent upon diesel fuel, significant increases in diesel fuel costs could
materially and adversely affect our results of operations and financial
condition if we are unable to pass increased costs on to customers through rate
increases or fuel surcharges. Historically, we have sought to recover a portion
of short-term increases in fuel prices from customers through fuel surcharges.
Fuel surcharges that can be collected do not always fully offset the increase in
the cost of diesel fuel. To the extent we are not successful in these
negotiations our results of operations may be adversely affected.

Difficulty in driver and independent contractor recruitment and retention may
have a materially adverse effect on our business.

Difficulty in attracting or retaining qualified drivers, including
independent contractors, could have a materially adverse effect on our growth
and profitability. Our independent contractors are responsible for paying for
their own equipment, fuel, and other operating costs, and significant increases
in these costs could cause them to seek higher compensation from us or seek
other opportunities within or outside the trucking industry. In addition,
competition for drivers, which is always intense, continues to increase. If a
shortage of drivers should continue, or if we were unable to continue to attract
and contract with independent contractors, we could be forced to limit our
growth, experience an increase in the number of our tractors without drivers,
which would lower our profitability, or be required to further adjust our driver
compensation package. We have increased our driver compensation on several
occasions recently. While no additional pay increases are planned for 2007,
increases in driver compensation could adversely affect our profitability if not
offset by a corresponding increase in rates.

We operate in a highly regulated industry, and increased costs of compliance
with, or liability for violation of, existing or future regulations could have a
materially adverse effect on our business.

Our operations are regulated and licensed by various U.S. agencies. Our
company drivers and independent contractors also must comply with the safety and
fitness regulations of the United States Department of Transportation, including
those relating to drug and alcohol testing and hours-of-service. Such matters as
weight and equipment dimensions are also subject to U.S. regulations. We also
may become subject to new or more restrictive regulations relating to fuel
emissions, drivers' hours-of-service, ergonomics, or other matters affecting
safety or operating methods. Other agencies, such as the EPA and the Department
of Homeland Security (the "DHS"), also regulate our equipment, operations, and
drivers. Future laws and regulations may be more stringent and require changes
in our operating practices, influence the demand for transportation services,



6
or require us to incur significant  additional  costs.  Higher costs incurred by
us, or by our suppliers who pass the costs onto us through higher prices, could
adversely affect our results of operations.

The DOT, through the Federal Motor Carrier Safety Administration Act,
imposes safety and fitness regulations on us and our drivers. New rules that
limit driver hours-of-service were adopted effective January 4, 2004, and then
modified effective October 1, 2005. The rules effective October 1, 2005, did not
substantially change the existing rules but have created a moderate reduction in
the amount of time available to drivers in longer lengths of haul, and reduced
equipment productivity in those lanes. The FMCSA is studying rules relating to
braking distance and on-board data recorders that could result in new rules
being proposed. We are unable to predict the effect of any proposed rules, but
we expect that any such proposed rules would increase costs in our industry, and
the on-board recorders potentially could decrease productivity and the number of
people interested in being drivers.

In the aftermath of the September 11, 2001 terrorist attacks, federal,
state, and municipal authorities have implemented and continue to implement
various security measures, including checkpoints and travel restrictions on
large trucks. The Transportation Security Administration (the "TSA") of the DHS
has adopted regulations that require determination by the TSA that each driver
who applies for or renews his or her license for carrying hazardous materials is
not a security threat. This could reduce the pool of qualified drivers, which
could require us to increase driver compensation, limit our fleet growth, or let
trucks sit idle. These regulations also could complicate the matching of
available equipment with hazardous material shipments, thereby increasing our
response time on customer orders and our non-revenue miles. As a result, it is
possible we may fail to meet the needs of our customers or may incur increased
expenses to do so. These security measures could negatively impact our operating
results.

Some states and municipalities have begun to restrict the locations and
amount of time where diesel-powered tractors, such as ours, may idle, in order
to reduce exhaust emissions. These restrictions could force us to alter our
drivers' behavior, purchase on-board power units that do not require the engine
to idle, or face a decrease in productivity.

Our operations are subject to various environmental laws and regulations, the
violation of which could result in substantial fines or penalties.

In addition to direct regulation by the DOT and other agencies, we are
subject to various environmental laws and regulations dealing with the handling
of hazardous materials, underground fuel storage tanks, and discharge and
retention of storm-water. We operate in industrial areas, where truck terminals
and other industrial facilities are located, and where groundwater or other
forms of environmental contamination have occurred. Our operations involve the
risks of fuel spillage or seepage, environmental damage, and hazardous waste
disposal, among others. We also maintain bulk fuel storage and fuel islands at
the majority of our facilities.

If we are involved in a spill or other accident involving hazardous
substances, or if we are found to be in violation of applicable laws or
regulations, it could have a materially adverse effect on our business and
operating results. If we should fail to comply with applicable environmental
regulations, we could be subject to substantial fines or penalties and to civil
and criminal liability.

Our business also is subject to the effects of new tractor engine design
requirements implemented by the EPA such as those that became effective October
1, 2002, and additional EPA emission requirements that become effective in
January 2007 which are discussed above under "Risk Factors - Increased prices
for, or increased costs of operating, new revenue equipment may materially and
adversely affect our earnings and cash flow." Additional changes in the laws and
regulations governing or impacting our industry could affect the economics of
the industry by requiring changes in operating practices or by influencing the
demand for, and the costs of providing, services to shippers.

We may not make acquisitions in the future, or if we do, we may not be
successful in integrating the acquired company, either of which could have a
materially adverse effect on our business.

Historically, acquisitions have been a part of our growth. There is no assurance
that we will be successful in identifying, negotiating, or consummating any
future acquisitions. If we fail to make any future acquisitions, our growth rate
could be materially and adversely affected. Any acquisitions we undertake could
involve the dilutive issuance of equity securities and/or incurring
indebtedness. In addition, acquisitions involve numerous risks, including
difficulties in assimilating the acquired company's operations, the diversion of



7
our management's attention from other business concerns,  risks of entering into
markets in which we have had no or only limited direct experience, and the
potential loss of customers, key employees, and drivers of the acquired company,
all of which could have a materially adverse effect on our business and
operating results. If we make acquisitions in the future, we cannot guarantee
that we will be able to successfully integrate the acquired companies or assets
into our business.

If we are unable to retain our key employees or find, develop, and retain
service center managers, our business, financial condition, and results of
operations could be adversely affected.

We are highly dependent upon the services of several executive officers and
key management employees. The loss of any of their services could have a
short-term, negative impact on our operations and profitability. We must
continue to develop and retain a core group of managers if we are to realize our
goal of expanding our operations and continuing our growth. Failing to develop
and retain a core group of managers could have a materially adverse effect on
our business. The Company has developed a structured business plan and
procedures to prevent a long-term effect on future profitability due to the loss
of key management employees.

We are highly dependent on a few major customers, the loss of one or more of
which could have a materially adverse effect on our business.

A significant portion of our revenue is generated from several major
customers. For the year ended December 31, 2006, our top 25 customers, based on
revenue, accounted for approximately 68% of our revenue. A reduction in or
termination of our services by one or more of our major customers could have a
materially adverse effect on our business and operating results.

Seasonality and the impact of weather affect our operations and profitability.

Our tractor productivity decreases during the winter season because
inclement weather impedes operations, and some shippers reduce their shipments
after the winter holiday season. Revenue can also be affected by bad weather and
holidays, since revenue is directly related to available working days of
shippers. At the same time, operating expenses increase and fuel efficiency
declines because of engine idling and harsh weather which creates higher
accident frequency, increased claims, and more equipment repairs. We can also
suffer short-term impacts from weather-related events such as hurricanes,
blizzards, ice storms, and floods that could harm our results or make our
results more volatile.

Ongoing insurance and claims expenses could significantly reduce our earnings.

Our future insurance and claims expense might exceed historical levels,
which could reduce our earnings. We self-insure for a portion of our claims
exposure resulting from workers' compensation, auto liability, general
liability, cargo and property damage claims, as well as employees' health
insurance. We also are responsible for our legal expenses relating to such
claims. We reserve currently for anticipated losses and expenses. We
periodically evaluate and adjust our claims reserves to reflect our experience.
However, ultimate results may differ from our estimates, which could result in
losses over our reserved amounts.

We maintain insurance above the amounts for which we self-insure with
licensed insurance carriers. Although we believe the aggregate insurance limits
should be sufficient to cover reasonably expected claims, it is possible that
one or more claims could exceed our aggregate coverage limits. Insurance
carriers have raised premiums for many businesses, including trucking companies.
As a result, our insurance and claims expense could increase, or we could raise
our self-insured retention when our policies are renewed. If these expenses
increase, or if we experience a claim in excess of our coverage limits, or we
experience a claim for which coverage is not provided, results of our operations
and financial condition could be materially and adversely affected.

We are dependent on computer and communications systems, and a systems failure
could cause a significant disruption to our business.

Our business depends on the efficient and uninterrupted operation of our
computer and communications hardware systems and infrastructure. We currently
use a centralized computer network and regular communication to achieve
system-wide load coordination. Our operations and those of our technology and
communications service providers are vulnerable to interruption by fire,
earthquake, power loss, telecommunications failure, terrorist attacks, Internet
failures, computer viruses, and other events beyond our control. In the event of
a significant system failure, our business could experience significant
disruption.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND
PURCHASES OF EQUITY SECURITIES

Price Range of Common Stock

The Company's common stock trades on the NASDAQ Global Select Market under
the symbol HTLD. The following table sets forth, for the calendar periods
indicated, the range of high and low price quotations for the Company's common
stock as reported by the NASDAQ Global Select Market and the Company's dividends
declared per common share from January 1, 2005 to December 31, 2006. The prices
and dividends declared have been restated to reflect a four-for-three stock
split on May 15, 2006.

Dividends Declared
Period High Low per Common Share
Calendar Year 2006
1st Quarter $ 18.75 $ 14.55 $.015
2nd Quarter 19.59 15.73 .020
3rd Quarter 18.51 14.10 .020
4th Quarter 17.71 14.79 .020

Calendar Year 2005
1st Quarter $ 17.33 $ 14.29 $ .015

3rd Quarter 16.31 14.09 .015
4th Quarter 16.64 14.06 .015

On January 30, 2007, the last reported sale price of our common stock on
the NASDAQ Global Select Market was $16.74 per share.

The prices reported reflect interdealer quotations without retail mark-ups,
markdowns or commissions, and may not represent actual transactions. As of
February 1, 2007, the Company had 232 stockholders of record of its common
stock. However, the Company estimates that it has a significantly greater number
of stockholders because a substantial number of the Company's shares are held of
record by brokers or dealers for their customers in street names.

Dividend Policy

During the third quarter of 2003, the Company announced the implementation
of a quarterly cash dividend program. The Company has declared and paid
quarterly dividends for the past fourteen consecutive quarters. The Company does
not currently intend to discontinue the quarterly cash dividend program.
However, future payments of cash dividends will depend upon the financial
condition, results of operations and capital requirements of the Company, as
well as other factors deemed relevant by the Board of Directors.

Stock Split

On April 20, 2006, the Board of Directors approved a four-for-three stock
split, affected in the form of a 33 percent stock dividend. The stock split
occurred on May 15, 2006, to shareholders of record as of May 5, 2006. This
stock split increased the number of outstanding shares to 98.4 million from 73.8
million. The number of common shares issued and outstanding and all per share
amounts have been adjusted to reflect the stock split for all periods presented.

Stock Repurchase

In September 2001, the Board of Directors approved the repurchase of up to
6.3 million shares of Heartland Express, Inc. common stock. During the year
ended December 31, 2006, 176,700 shares were repurchased for $2.5 million at
approximately $14.41 per share and the shares were retired. The cost of such
shares purchased and retired in excess of their par value in the amount of
approximately of $2.5 million was charged to retained earnings.


10
Share Based Compensation

On March 7, 2002, the Company's chief executive officer transferred 181,500
of his own shares establishing a restricted stock plan on behalf of key
employees. The shares vest over a five year period or upon death or disability
of the recipient. The shares were valued at the March 7, 2002 market value of
approximately $2.0 million. The market value of $2.0 million is being amortized
over a five year period as compensation expense. Compensation expense of
$376,029, $363,568 and $380,427 for the years ended December 31, 2006, 2005, and
2004, respectively, is recorded in salaries, wages, and benefits on the
consolidated statement of income. As of December 31, 2006, there was $62,672 of
unearned compensation cost related to the restricted stock granted. This cost
will be recognized over the first quarter of 2007. All unvested shares are
included in the Company's 98.3 million outstanding shares.

A summary of the Company's non-vested restricted stock as of December 31,
2006, and changes during the twelve months ended December 31, 2006 is presented
in the table below:

Grant-date
Shares Fair Value

Vested (34,000) 11.00
Forfeited - -
______ __________
Non-vested stock outstanding at December 31, 2006 34,200 $ 11.00
====== ==========

The fair value of the shares vested was $578,245 and $549,201 for the twelve
months ended December 31, 2006 and 2005, respectively.

In December 2004, the FASB issued SFAS No. 123(R), "Share-Based Payment," a
revision of SFAS No. 123, which addresses the accounting for share-based payment
transactions. SFAS No. 123(R) eliminates the ability to account for employee
share-based compensation transactions using APB Opinion No. 25, "Accounting for
Stock Issued to Employees," and generally requires instead that such
transactions be accounted and recognized in the consolidated statement of income
based on their fair value. SFAS No. 123(R) also requires entities to estimate
the number of forfeitures expected to occur and record expense based upon the
number of awards expected to vest. The Company implemented SFAS No. 123(R) on
January 1, 2006. The unamortized portion of unearned compensation was
reclassified to retained earnings upon implementation. The amortization of
unearned compensation is being recorded as additional paid-in capital effective
January 1, 2006. The implementation of SFAS No. 123(R) had no effect on the
Company's results of operations for the year ended December 31, 2006.

Non-monetary Transactions" ("SFAS 153"). The prospective application of SFAS 153
after June 30, 2005 resulted in the immediate recognition of gains from the
trade-in of revenue equipment rather than reduction in the cost of the new
revenue equipment. The recognition of gains from trade-in of revenue equipment
is offset over the equipment life by increased depreciation expense. For the
twelve month period of 2006 and the six month period of 2005, gains resulting
from the adoption of SFAS 153 were $14.8 million for 2006 and $6.1 million for
2005, net of associated increase in depreciation expense. Management believes
that gains reported in future periods will not be at the same level as reported
in the 2006 and 2005 periods.
(3) The Company increased the amount accrued for workers' compensation by $2.9
million and decreased the amount accrued for accident liability claims by $11.2
million during the 2003 period as a result of actuarial studies.

ITEM 7. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Overview

Heartland Express, Inc. is a short-to-medium haul truckload carrier. The
Company transports freight for major shippers and generally earns revenue based
on the number of miles per load delivered. The Company provides regional dry van
truckload services from nine regional operating centers including a regional
operation based at its corporate headquarters. The Company's nine regional
operating centers accounted for 73.2% of the 2006 operating revenues. The
Company expanded to the Western United States in the second quarter of 2005 with
the opening of a regional operating center in Phoenix, Arizona. The Company
takes pride in the quality of the service that it provides to its customers. The
keys to maintaining a high level of service are the availability of late-model
equipment and experienced drivers.

Operating efficiencies and cost controls are achieved through equipment
utilization, operating a fleet of late model equipment, maintaining an industry
leading driver to non-driver employee ratio, and the effective management of
fixed and variable operating costs. At December 31, 2006, the Company's tractor
fleet had an average age of 1.2 years while the trailer fleet had an average age
of 3.1 years. The Company has grown internally by providing quality service to
targeted customers with a high density of freight in the Company's regional
operating areas. In addition to the development of its regional operating
centers, the Company has made five acquisitions since 1987. Future growth is
dependent upon several factors including the level of economic growth and the
related customer demand, the available capacity in the trucking industry,
potential of acquisition opportunities, and the availability of experienced
drivers.

The Company achieved record operating results during the year ended
December 31, 2006. The Company ended the year with operating revenues of $571.9
million, including fuel surcharges, net income of $87.2 million, and earnings
per share of $0.89 on average outstanding shares of 98.4 million. The Company
posted a 78.4% operating ratio (operating expenses as a percentage of operating
revenues) and a 15.2% net margin. The Company ended the year with cash, cash
equivalents, and short-term investments of $331.3 million and a debt-free
balance sheet. The Company has total assets of $669.1 million at December 31,
2006. The Company achieved a return on assets of 14.0% and a return on equity of
18.6%, both improvements over 2005. The Company's cash flow from operations for
the year of $128.1 million was 22.4% of operating revenues.

The 2006 and 2005 periods have been favorably impacted by gains on the
trade-in of revenue equipment. Prior to the implementation of Statement of
Financial Accounting Standard No. 153 on July 1, 2005, the gains related to
trade-in of revenue producing equipment was deferred as a reduction of the basis
of the new equipment. For the years ended December 31, 2006 and 2005, gains from
the trade-in of revenue equipment were $14.8 million and $6.1 million,
respectively, net of associated increase in depreciation expense. Management
believes that gains reported in future periods will not be at the same level as
reported in 2006.

The Company hires only experienced drivers with safe driving records. In
order to attract and retain experienced drivers who understand the importance of
customer service, the Company increased pay for all drivers by $0.03 per mile
during both the first quarters of 2004 and 2005. Effective October 2, 2004, the
Company began paying all drivers an incremental amount for miles driven in the
upper Northeastern United States. In 2006, the Company implemented additional
pay increases for drivers in selected operations groups and a fleet-wide
incentive for all drivers maintaining a valid hazardous materials endorsement on
their commercial driver's license. The Company has solidified its position as an
industry leader in driver compensation with these aforementioned increases.

======= ======= =======

Year Ended December 31, 2006 Compared With Year Ended December 31, 2005

Operating revenue increased $48.1 million (9.2%), to $571.9 million in 2006
from $523.8 million in 2005, as a result of the Company's expansion of its fleet
and customer base as well as improved freight rates. Operating revenue for both
periods was positively impacted by fuel surcharges assessed to the customer
base. Fuel surcharge revenue increased $21.7 million, (36.3%) to $81.4 million
in 2006 from $59.7 million reported in 2005.

Salaries, wages, and benefits increased $15.0 million (8.6%), to $189.2
million in 2006 from $174.2 million in 2005. These increases were the result of
increased reliance on employee drivers due to a decrease in the number of
independent contractors utilized by the Company and a driver pay increase. The
Company increased driver pay by $0.01 per mile in January 2006 for all drivers
maintaining a valid hazardous materials endorsement on their commercial driver's
license and implemented quarterly pay increases for selected operating
divisions. These increases to driver compensation resulted in a cost increase of
approximately $5.6 million in 2006. During 2006, employee drivers accounted for
94% and independent contractors 6% of the total fleet miles, compared with 92%
and 8%, respectively, in 2005. Workers' compensation expense increased $0.6
million (18.0%) to $4.2 million in 2006 from $3.6 million in 2005 due to an
increase in frequency and severity of claims. Health insurance expense increased
$0.8 million (10.3%) to $8.5 million in 2006 from $7.7 million in 2005 due to an
increase in frequency and severity of claims and increased reliance on employee
drivers.

Rent and purchased transportation decreased $5.2 million (17.7%), to $24.4
million in 2006 from $29.6 million in 2005. This reflected the Company's
decreased reliance upon independent contractors. Rent and purchased
transportation for both periods includes amounts paid to independent contractors
for fuel stabilization. The Company increased the base mileage rate for
independent contractors by $0.03 per mile in the first quarter of 2005 for the
second consecutive year. In the first quarter of 2006, the Company increased the
independent contractor base mileage pay by $0.01 per mile for all independent
contractors maintaining a hazardous materials endorsement on their commercial
driver's license, and an additional $0.01 per mile per quarter beginning on
April 1, 2006.

Fuel increased $22.7 million (18.4%), to $146.3 million in 2006 from $123.6
million in 2005. The increase is the result of increased fuel prices and an
increased reliance on company-owned tractors. The Company's fuel cost per
company-owned tractor mile increased 13.8% in 2006 compared to 2005. Fuel cost
per mile, net of fuel surcharge, decreased 2.3% in 2006 compared to 2005. The

14
Company's  fuel  cost  per  gallon  increased  11.7%  in 2006  compared  to 2005
primarily due to continued instability in the Middle East and concerns over
domestic inventory levels.

Operations and maintenance decreased $2.3 million (15.4%), to $12.6 million
in 2006 from $14.9 million in 2005. The decrease is primarily attributed to the
improved average age of the revenue equipment in our fleet. The average age of
our tractor fleet is 1.2 years while the average age of the trailer fleet is 3.1
years. In 2005, the average age of tractors was 1.5 years with trailers
averaging 3.2 years.

Insurance and claims decreased $1.3 million (7.3%), to $16.6 million in
2006 from $17.9 million in 2005 due to a decrease in the frequency and severity
of claims.

Depreciation increased $9.1 million (23.9%), to $47.3 million in 2006 from
$38.2 million in 2005. This increase is attributable to the growth of our
company-owned tractor and trailer fleet, an increased cost of new tractors
primarily associated with the EPA-mandated clean air engines, and the
implementation of SFAS No. 153. New tractors have a higher cost than the models
being replaced due to EPA-mandated clean air standards. As of December 31, 2006,
100% of the Company's tractor fleet had the EPA clean air engine compared to
68.6% at December 31, 2005. For the year ended December 31, 2006, as a result of
SFAS No. 153, approximately $2.8 million of additional depreciation was
recognized due to a higher depreciable basis of revenue equipment acquired
through trade-ins. For the same period of 2005, the additional depreciation
attributable to SFAS No. 153 was $369,000. In future periods, we expect
depreciation will increase as we continue to upgrade our fleet in compliance
with EPA-mandated engine changes and due to the impact of SFAS No. 153.

Other operating expenses increased $0.7 million (4.0%), to $17.4 million in
2006 from $16.7 million in 2005. Other operating expenses consist of costs
incurred for advertising expense, freight handling, highway tolls, driver
recruiting expenses, and administrative costs.

Gain on the disposal of property and equipment increased $10.1 million
(125.9%), to $18.1 million in 2006 from $8.0 million in the 2005 period. The
2006 period includes $17.6 million from gains on trade-ins of revenue equipment
which are recognized under SFAS No. 153 compared to $6.5 million for the same
period of 2005. Prior to the implementation of SFAS No 153, gains from trade-ins
of revenue equipment were deferred as a reduction of the basis of the new
equipment. Management does not believe gains in the future will be at similar
levels realized in the 2006 period.

Interest income increased $4.3 million (59.1%), to $11.7 million in 2006
from $7.4 million in 2005. The increase is the result of higher average balances
of cash, cash equivalents, and short-term investments and higher yields than
2005.

The Company's effective tax rate was 35.5% for 2006 and 2005, respectively.
Income taxes have been provided for at the statutory federal and state rates,
adjusted for certain permanent differences between financial statement income
and income for tax reporting.

As a result of the foregoing, the Company's operating ratio (operating
expenses as a percentage of operating revenue) was 78.4% during the year ended
December 31, 2006 compared with 80.1% for 2005. Net income increased $15.3
million (21.2%), to $87.2 million for the year ended December 31, 2006 from
$71.9 million for the year ended December 31, 2005.

Year Ended December 31, 2005 Compared With Year Ended December 31, 2004

Operating revenue increased $66.7 million (14.6%), to $523.8 million in
2005 from $457.1 million in 2004, as a result of the Company's expansion of its
fleet and customer base as well as improved freight rates and improved
utilization of fleet capacity. Operating revenue for both periods was positively
impacted by fuel surcharges assessed to the customer base. Fuel surcharge
revenue increased $31.2 million, (109.5%), to $59.7 million in 2005 from $28.5
million reported in 2004.

Salaries, wages, and benefits increased $16.7 million (10.6%), to $174.2
million in 2005 from $157.5 million in 2004. These increases were the result of
increased reliance on employee drivers due to a decrease in the number of
independent contractors utilized by the Company and a driver pay increase. The
Company increased driver pay by $0.03 per mile in the first quarter of 2005 for
the second consecutive year. During the fourth quarter of 2004, the Company
implemented additional mileage pay for miles driven in the Northeast corridor of
the United States. These increases to driver compensation resulted in a cost

15
increase of approximately  $9.2 million in 2005.  During 2005,  employee drivers
accounted for 92% and independent contractors 8% of the total fleet miles,
compared with 88% and 12%, respectively, in 2004. Workers' compensation expense
decreased $4.0 million (53.0%) to $3.6 million in 2005 from $7.6 million in 2004
due to a decrease in frequency and severity of claims. Health insurance expense
increased $3.2 million (71.2%) to $7.7 million in 2005 from $4.5 million in 2004
due to an increase in frequency and severity of claims and increased reliance on
employee drivers.

Rent and purchased transportation decreased $7.2 million (19.4%), to $29.6
million in 2005 from $36.8 million in 2004. This reflected the Company's
decreased reliance upon independent contractors. Rent and purchased
transportation for both periods includes amounts paid to independent contractors
for fuel stabilization. The Company increased the base mileage rate for
independent contractors by $0.03 per mile in the first quarter of 2005 for the
second consecutive year. During the fourth quarter of 2004, the Company
implemented additional mileage pay for miles driven in the Northeast corridor of
the United States. These increases resulted in additional cost of $0.8 million
in 2005.

Fuel increased $40.3 million (48.4%), to $123.6 million in 2005 from $83.3
million in 2004. The increase is the result of increased fuel prices, an
increased reliance on company-owned tractors, and a decrease in fuel economy
associated with the EPA-mandated clean air engines. The Company's fuel cost per
company-owned tractor mile increased 39.7% in 2005 compared to 2004. Fuel cost
per mile, net of fuel surcharge, increased 12.0% in 2005 compared to 2004. The
Company's fuel cost per gallon increased 34.5% in 2005 compared to 2004
primarily due to continued instability in the Middle East and severe hurricanes
in the Gulf Coast region. In addition, the fuel economy for tractors with the
EPA-mandated clean air engines decreased 7.3%. In 2005, tractors with the
EPA-mandated clean air engine accounted for 47.9% of the miles generated by the
company-owned fleet.

Operations and maintenance increased $2.0 million (15.6%), to $14.9 million
in 2005 from $12.9 million in 2004. The increase is primarily attributable to
the growth of the company-owned tractor and trailer fleets and the associated
costs to maintain revenue equipment.

Insurance and claims increased $1.4 million (8.4%), to $17.9 million in
2005 from $16.5 million in 2004 due to an increase in the frequency and severity
of claims.

Depreciation increased $8.6 million (29.0%), to $38.2 million in 2005 from
$29.7 million in 2004. This increase is attributable to the growth of our
company-owned tractor and trailer fleet, an increased cost of new tractors
primarily associated with the EPA-mandated clean air engines, and the
implementation of SFAS No. 153. New tractors have a higher cost than the models
being replaced due to EPA-mandated clean air standards. As of December 31, 2005,
68.6% of the Company's tractor fleet had the EPA clean air engine compared to
32.6% at December 31, 2004. For the year ended December 31, 2005, as a result of
SFAS No. 153, approximately $369,000 of additional depreciation was recognized
due to a higher depreciable basis of revenue equipment acquired through
trade-ins.

Other operating expenses increased $2.3 million (15.9%), to $16.7 million
in 2005 from $14.4 million in 2004. Other operating expenses consist of costs
incurred for advertising expense, freight handling, highway tolls, driver
recruiting expenses, and administrative costs.

Gain on the disposal of property and equipment increased $7.8 million
(4494.1%), to $8.0 million in 2005 from $0.2 million in the 2004 period. For
2005, $6.5 million represents gains on trade-ins of revenue equipment which are
recognized under SFAS No. 153. Prior to the implementation of SFAS No 153 on
July 1, 2005, gains were deferred as a reduction of the basis of the new
equipment.

Interest income increased $4.3 million (140.1%), to $7.4 million in 2005
from $3.1 million in 2004. The increase is the result of higher average balances
of cash, cash equivalents, and short-term investments and higher yields than
2004.

The Company's effective tax rate was 35.5% and 35.4% in 2005 and 2004,
respectively. Income taxes have been provided for at the statutory federal and
state rates, adjusted for certain permanent differences between financial
statement income and income for tax reporting.

As a result of the foregoing, the Company's operating ratio (operating
expenses as a percentage of operating revenue) was 80.1% during the year ended
December 31, 2005 compared with 79.5% for 2004. Net income increased $9.5
million (15.2%), to $71.9 million for the year ended December 31, 2005 from
$62.4 million for the year ended December 31, 2004.

16
Inflation and Fuel Cost

Most of the Company's operating expenses are inflation-sensitive, with
inflation generally producing increased costs of operations. During the past
three years, the most significant effects of inflation have been on revenue
equipment prices and the compensation paid to the drivers. Innovations in
equipment technology and comfort have resulted in higher tractor prices, and
there has been an industry-wide increase in wages paid to attract and retain
qualified drivers. The Company historically has limited the effects of inflation
through increases in freight rates and certain cost control efforts. In addition
to inflation, fluctuations in fuel prices can affect profitability. Most of the
Company's contracts with customers contain fuel surcharge provisions. Although
the Company historically has been able to pass through most long-term increases
in fuel prices and operating taxes to customers in the form of surcharges and
higher rates, shorter-term increases are not fully recovered.

Fuel prices have remained high throughout 2004, 2005, and 2006, thus
increasing our cost of operations. In addition to the increased fuel costs, the
reduced fuel efficiency of the new EPA engines has put additional pressure on
profitability due to increased fuel consumption. Competitive conditions in the
transportation industry, such as lower demand for transportation services, could
affect the Company's ability to obtain rate increases or fuel surcharges.

Liquidity and Capital Resources

The growth of the Company's business requires significant investments in
new revenue equipment. Historically the Company has been debt-free, funding
revenue equipment purchases with cash flow provided by operations. The Company
also obtains tractor capacity by utilizing independent contractors, who provide
a tractor and bear all associated operating and financing expenses. The
Company's primary source of liquidity for the year ended December 31, 2006, was
net cash provided by operating activities of $128.1 million compared to $104.9
million in 2005 due primarily to higher net income in 2006. Cash flow from
operating activities was 22.4% of operating revenues in 2006 compared with 20.0%
in 2005.

Capital expenditures for property and equipment, net of trade-ins, totaled
$76.1 million for 2006 compared to $49.2 million during 2005. We currently
expect capital expenditures for revenue equipment, net of trades, to be
approximately $48.7 million in 2007. In addition, the Company began construction
of a new facility in Phoenix, Arizona in 2006. This facility is expected to be
completed in the first quarter of 2007 with additional capital expenditures of
$2.2 million. These projected capital expenditures will be funded by cash flows
from operations. Total expenditures for the new corporate headquarters and shop
facility in North Liberty, Iowa are expected to be approximately $12.0 million
to $15.0 million. Construction is expected to be completed in the second quarter
of 2007.

The Company paid cash dividends of $6.9 million in 2006 compared to $6.0
million in 2005. The Company began paying cash dividends in the third quarter of
2003. The Company declared a $2.0 million cash dividend in December 2006,
payable on January 2, 2007.

The Company paid income taxes of $41.3 million in 2006 compared to $42.1
million in 2005. The decrease is primarily attributable to an increase in
interest income not subject to tax along with an increase in tax depreciation.

During the year ended December 31, 2006, 176,700 shares of the Company's
common stock were repurchased for $2.5 million at approximately $14.41 per
share. The repurchased shares were subsequently retired. At December 31, 2006,
the Company has 4.9 million shares remaining under the current Board of Director
repurchase authorization. Future purchases are dependent upon market conditions.

Management believes the Company has adequate liquidity to meet its current
and projected needs. The Company will continue to have significant capital
requirements over the long-term which are expected to be funded by cash flow
provided by operations and from existing cash, cash equivalents, and short-term
investments. The Company ended the year with $331.3 million in cash, cash
equivalents, and short-term investments and no debt. Net working capital for the
year ended December 31, 2006 increased by $32.7 million over 2005. Based on the
Company's strong financial position, management believes outside financing could
be obtained, if necessary, to fund capital expenditures.

Off-Balance Sheet Transactions

The Company's liquidity is not materially affected by off-balance sheet
transactions.

Contractual Obligations and Commercial Commitments

The following sets forth our contractual obligations and commercial
commitments at December 31, 2006. As of December 31, 2006 the Company has no
debt outstanding.

</TABLE>

(1) The purchase obligations reflect the total purchase price of
approximately $14.9 million, for tractors scheduled to be delivered in
the first quarter of 2007. These purchases are expected to be financed
by existing cash and short-term investment balances, and with cash
flows from operations.

(2) The purchase obligations reflect $15.0 million for the new
corporate headquarters. The anticipated costs for the new corporate
headquarters are expected to range from $12.0 - $15.0 million. The
corporate headquarters will be funded with proceeds from the sale of
the current corporate headquarters and from existing cash and
short-term investment balances, and with cash flows from operations.

(3) The operating lease obligations include the rental of facilities
at the Company's corporate headquarters. This lease expires May 31,
2010 and contains a five-year renewal option (See Note 5 for further
details). In 2005, the Company announced the construction of a new
corporate headquarters which is expected to be ready for occupancy in
2007. The lease will be cancelled upon the occupancy of the new
corporate headquarters and shop facility. The operating lease
obligations also include the lease of a terminal space in Phoenix,
Arizona. This lease expired June 30, 2006 and contains two one-year
renewal options. The Company extended the lease for a one-year term in
June 2006. The Company anticipates occupancy in the new Phoenix
terminal in the first quarter, 2007. The lease will be canceled upon
occupancy of the new Phoenix terminal.

Critical Accounting Policies

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting periods.

The Company's management routinely makes judgments and estimates about the
effect of matters that are inherently uncertain. As the number of variables and
assumptions affecting the probable future resolution of the uncertainties
increase, these judgments become even more subjective and complex. The Company
has identified certain accounting policies, described below, that are the most
important to the portrayal of the Company's current financial condition and
results of operations.

The most significant accounting policies and estimates that affect the
financial statements include the following:

* Revenue is recognized when freight is delivered.


18
*    Selections of estimated  useful lives and salvage  values for purposes
of depreciating tractors and trailers. Depreciable lives of tractors
and trailers are 5 and 7 years, respectively. Estimates of salvage
value are based upon the expected market values of equipment at the
end of the expected useful life.
* Management estimates accruals for the self-insured portion of pending
accident liability, workers' compensation, physical damage and cargo
damage claims. These accruals are based upon individual case
estimates, including reserve development, and estimates of
incurred-but-not-reported losses based upon past experience.
* Management judgment is required to determine the provision for income
taxes and to determine whether deferred income taxes will be realized.
Deferred tax assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which the
temporary differences are expected to be recovered or settled. A
valuation allowance is required to be established for the amount of
deferred income tax assets that are determined not to be realizable. A
valuation allowance for deferred income tax assets has not been
established due to the profitability of the Company's business.

Management periodically re-evaluates these estimates as events and
circumstances change. These factors may significantly impact the Company's
results of operations from period-to-period.

New Accounting Pronouncements

See Note 1 of the consolidated financial statements for a full description
of recent accounting pronouncements and the respective dates of adoption and
effects on results of operations and financial position.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company purchases only high quality liquid investments. Primarily all
investments as of December 31, 2006 have an original maturity or interest reset
date of six months or less. Due to the short term nature of the investments the
Company is exposed to minimal market risk related to its cash equivalents and
investments.

The Company has no debt outstanding as of December 31, 2006 and therefore,
has no market risk related to debt.

As of December 31, 2006, the Company has no derivative financial
instruments to reduce its exposure to diesel fuel price fluctuations.

HEARTLAND EXPRESS, INC.
AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Significant Accounting Policies

Nature of Business:

Heartland Express, Inc., (the "Company") is a short-to-medium-haul,
truckload carrier of general commodities. The Company provides nationwide
transportation service to major shippers, using late-model equipment and a
combined fleet of company-owned and owner-operator tractors. The Company's
primary traffic lanes are between customer locations east of the Rocky
Mountains. In 2005, the Company expanded to the Western United States with the
opening of a terminal in Phoenix, Arizona. The Company operates the business as
one reportable segment.

Principles of Consolidation:

The accompanying consolidated financial statements include the parent
company, Heartland Express, Inc., and its subsidiaries, all of which are wholly
owned. All material intercompany items and transactions have been eliminated in
consolidation.

Use of Estimates:

The preparation of financial statements in conformity with U.S. 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 during the
reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents:

Cash equivalents are short-term, highly liquid investments with
insignificant interest rate risk and original maturities of three months or
less. Restricted and designated cash and short-term investments totaling $5.5
million in 2006 and $4.7 million in 2005 are classified as other assets. The
restricted funds represent those required for self-insurance purpose and
designated funds that are earmarked for a specific purpose not for general
business use.

Short-term Investments:

The Company investments are primarily in the form of tax free municipal
bonds with interest reset provisions or short-term municipal bonds. The
investments typically have a put option of 28 or 35 days. At the reset date the
Company has the option to roll the investment over or sell. The Company receives
the par value of the investment on the reset date if sold. The cost approximates
fair value due to the nature of the investment. Therefore, accumulated other
comprehensive income (loss) has not been recognized as a separate component of
stockholders' equity. Investment income received is generally exempt from
federal income taxes.

Revenue and Expense Recognition:

Revenue, drivers' wages and other direct operating expenses are recognized
when freight is delivered. Sales and other taxes collected from customers and
remitted to the government are recorded on a net basis.

Trade Receivables and Allowance for Doubtful Accounts:

Revenue is recognized when freight is delivered creating a credit sale and
an accounts receivable. Credit terms for customer accounts are typically on a
net 30 day basis. The Company uses a percentage of aged receivable method in
determining the allowance for bad debts. The Company reviews the adequacy of its
allowance for doubtful accounts on a monthly basis. The Company is aggressive in
its collection efforts resulting in a low number of write-offs annually.
Conditions that would lead an account to be considered uncollectible include;
customers filing bankruptcy and the exhaustion of all practical collection
efforts. The company will use the necessary legal recourse to recover as much of
the receivable as is practical under the law.

25
Property, Equipment, and Depreciation:

Property and equipment are stated at cost, while maintenance and repairs
are charged to operations as incurred.

Effective July 1, 2005, gains from the trade of revenue equipment are being
recognized in operating income in compliance with Statement of Financial
Accounting Standards ("SFAS") No. 153, "Accounting for Non-monetary
Transactions". Prior to July 1, 2005, gains from the trade-in of revenue
equipment were deferred and presented as a reduction of the depreciable basis of
new revenue equipment. Operating income for the years ended December 31, 2006
and 2005 were favorably impacted by $14.8 million and $6.1 million,
respectively, from gains on the trade-in of revenue equipment, net of the
associated increase in depreciation expense as a result of the higher
depreciable basis of traded revenue equipment since July 1, 2005. SFAS No. 153
was adopted prospectively July 1, 2005, thus trade-ins that occurred prior to
July 1, 2005 did not impact gain on sale. Management does not believe that the
level of gains realized for the 2006 and 2005 periods will continue into the
future. Depreciation expense is expected to increase due to the higher
depreciable base of revenue equipment.

Depreciation for financial statement purposes is computed by the
straight-line method for all assets other than tractors. Tractors are
depreciated by the 125% declining balance method. Tractors are depreciated to
salvage values of $15,000 while trailers are depreciated to salvage values of
$4,000.

Lives of the assets are as follows:
Years
Land improvements and building 3-30
Furniture and fixtures 2-3
Shop and service equipment 3-5
Revenue equipment 5-7

Advertising Costs:

The Company expenses all advertising costs as incurred. Advertising costs
are included in other operating expenses in the consolidated statements of
income.

Goodwill:

Goodwill is tested at least annually for impairment by applying a fair
value based analysis in accordance with the provisions of SFAS No. 142,
"Goodwill and Other Intangible Assets". Management determined that no impairment
charge was required for the years ended December 31, 2006, 2005, and 2004.

Earnings per Share:

Earnings per share are based upon the weighted average common shares
outstanding during each year. The Company has no common stock equivalents;
therefore, diluted earnings per share are equal to basic earnings per share. All
earnings per share data presented reflect the four-for-three stock split on May
15, 2006.

Workers' Compensation and Accident Costs:

Insurance accruals reflect the estimated cost for auto liability, cargo
loss and damage, bodily injury and property damage (BI/PD), and workers'
compensation claims, including estimated loss development and loss adjustment
expenses, not covered by insurance. The cost of cargo and BI/PD insurance and
claims are included in insurance and claims expense, while the costs of workers'
compensation insurance and claims are included in salaries, wages, and benefits
in the consolidated statements of income.

Share-Based Compensation:

The Company recorded share-based compensation arrangements in accordance
with SFAS No. 123 (revised 2004), "Share-Based Payment." This standard requires
that share-based transactions be accounted for and recognized in the statement
of income based on their fair value. At December 31, 2006, the Company has one
share-based compensation program, which is further detailed in Note 7:
Stockholders' Equity below. That program expires in March of 2007 and, at this
date; the Company does not plan any additional share-based programs.

26
Impairment of Long-Lived Assets:

The Company periodically evaluates property and equipment for impairment
upon the occurrence of events or changes in circumstances that indicate the
carrying amount of assets may not be recoverable. Recoverability of assets to be
held and used is measured by a comparison of the carrying amount of an asset
group to future net undiscounted cash flows expected to be generated by the
group. If such assets are considered to be impaired, the impairment to be
recognized is measured by the amount over which the carrying amount of the
assets exceeds the fair value of the assets. There were no impairment charges
recognized during the years ended December 31, 2006, 2005, and 2004.

Income Taxes:

The Company uses the asset and liability method of accounting for income
taxes. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statements
carrying amount of existing assets and liabilities and their respective tax
basis. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled.

New Accounting Pronouncements:

In June 2006, the FASB issued FASB Interpretation No. 48 "Accounting for
Uncertainty in Income Taxes (an interpretation of FASB Statement No. 109)",
which is effective for fiscal years beginning after December 15, 2006 with
earlier adoption encouraged. This interpretation was issued to clarify the
accounting for uncertainty in income taxes recognized in the financial
statements by prescribing a recognition threshold and measurement attribute for
the financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. The Company will record a cumulative
adjustment of approximately $5.4 million to decrease the January 1, 2007
retained earnings upon adoption.

In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements".
This Statement defines fair value, establishes a framework for measuring fair
value in generally accepted accounting principles(GAAP), and expands disclosures
about fair value measurements. The provisions of SFAS No. 157 are effective as
of the beginning of the first fiscal year that begins after November 15, 2007.
As of December 31, 2006, management believes that SFAS No. 157 will have no
effect on the financial position, results of operations, and cash flows of the
Company.

In June 2006, the FASB ratified the consensus reached on Emerging Issues
Task Force (EITF) Issue No. 06-03, "How Sales Taxes Collected from Customers and
Remitted to Governmental Authorities Should be Presented in the Income Statement
(that is, Gross Versus Net Presentation)." The EITF reached a consensus that the
presentation of taxes on either a gross or net basis is an accounting policy
decision that requires disclosure. EITF 06-03 is effective for the first interim
or annual reporting period after December 15, 2006. The Company revenues are
typically considered "sales tax exempt" of requiring the collection of amounts
that must further be remitted to a taxing authority. To the extent that the
Company does collect taxes, those taxes are recorded on a net basis, which we
have previously disclosed. The adoption of EITF 06-03 will not have any effect
on the Company's financial position, results of operation or cash flows.

Reclassifications:

Certain reclassifications have been made to prior year financial statements
to conform to the December 31, 2006 presentation.

2. Adopted Accounting Pronouncements

In December 2004, the FASB issued SFAS No. 123 (revised 2004), "Share-Based
Payment" ("SFAS 123R"), a revision of SFAS No. 123, "Accounting for Stock Based
Compensation". SFAS 123R eliminates the ability to account for employee
share-based compensation transactions using APB Opinion No. 25, "Accounting for
Stock Issued to Employees", and generally requires instead that such
transactions be accounted for and recognized in the statement of income based on
their fair value. SFAS 123R also requires entities to estimate the number of
forfeitures expected to occur and record expense based upon the number of awards
expected to vest. The Company implemented SFAS No. 123(R) on January 1, 2006.
The unamortized portion of unearned compensation was reclassified to retained
earnings upon implementation.

27
The amortization of unearned compensation is being
recorded as additional paid-in capital effective January 1, 2006. The
implementation of SFAS No. 123(R) had no effect on the Company's results of
operations for the twelve months ended December 31, 2006.

In September 2006, the SEC issued Staff Accounting Bulletin No. 108,
"Considering the Effects of Prior Year Misstatements when Quantifying
Misstatements in Current Year Financial Statements" (SAB 108), to address
diversity in practice in quantifying financial statement misstatements. SAB 108
requires an entity to quantify misstatements using a balance sheet and income
statement approach and to evaluate whether either approach results in
quantifying an error that is material in light of relevant quantitative and
qualitative factors. SAB 108 is effective as of the beginning of the Company's
2006 fiscal year, allowing a one-time transitional cumulative effect adjustment
to retained earnings as of January 1, 2006 for errors that were not previously
deemed material, but are material under the guidance in SAB 108. The Company
adopted the provisions of SAB No. 108 and recorded a $15.9 million cumulative
adjustment to the January 1, 2006 retained earnings for a previously unrecorded
state income tax exposure liability and related deferred tax liability. The
amount recorded pertains to potential state income tax liabilities for the years
1996 through 2005 and the impact on deferred tax liabilities for those same
years. These errors were considered immaterial under the Company's previous
method of evaluating misstatements.

3. Concentrations of Credit Risk and Major Customers

The Company's major customers represent the consumer goods, appliances,
food products and automotive industries. Credit is granted to customers on an
unsecured basis. The Company's five largest customers accounted for 35% of total
gross revenues for the year ended December 31, 2006 and 32% and 33% for the
years ended December 31, 2005 and 2004 respectively. Operating revenue from one
customer exceeded 10% of total gross revenues in 2006, 2005, and 2004. Annual
revenues for this customer were $79.5 million, $66.2 million, and $62.7 million
for the years ended December 31, 2006, 2005, and 2004, respectively.

4. Income Taxes

Deferred income taxes are determined based upon the differences between the
financial reporting and tax basis of the Company's assets and liabilities.
Deferred taxes are provided at the enacted tax rates to be in effect when the
differences reverse.

Deferred tax assets and liabilities as of December 31 are as follows:

2006 2005
------------ ------------
Deferred income tax liabilities,
related to property and equipment $ 57,623,000 $ 48,012,000
============ ============
Deferred income tax assets:
Allowance for doubtful accounts $ 306,000 $ 306,000
Accrued expenses 6,691,000 6,436,000
Insurance accruals 22,351,000 21,143,000
Other (171,000) 836,000
------------ ------------
Deferred income tax assets $ 29,177,000 $ 28,721,000
============ ============

The Company has not recorded a valuation allowance. In management's
opinion, it is more likely than not that the Company will be able to utilize its
deferred tax assets in future periods as a result of the Company's history of
profitability, taxable income and reversal of deferred tax liabilities.

The income tax provision is
as follows:
2006 2005 2004
----------- ----------- -----------
Current income taxes:
Federal $35,820,886 $37,708,855 $27,905,357
State 7,055,716 4,499,238 2,808,197
----------- ----------- -----------
42,876,602 42,208,093 30,713,554

Deferred income taxes:

5,101,000 (2,630,000) 3,469,000
----------- ----------- -----------
Total $47,977,602 $39,578,093 $34,182,554
=========== =========== ===========

28
The income tax provision differs from the amount determined by applying the
U.S. federal tax rate as follows:

2006 2005 2004
----------- ----------- -----------
Federal tax at statutory rate (35%) $47,301,860 $39,019,349 $33,820,200
State taxes, net of federal benefit 4,809,000 2,401,000 1,363,000
Non-taxable interest income (4,039,000) (2,540,000) (1,045,000)
Other (94,258) 697,744 44,354
----------- ----------- -----------
$47,977,602 $39,578,093 $34,182,554
=========== =========== ===========

As stated in Note 2 above, the Company adopted SAB 108 by recording a $15.9
million cumulative adjustment to retained earnings. The Company adjusted
retained earnings due to a previously unrecorded state income tax exposure
liability of $11.8 million and related increase in the deferred tax liability of
$4.1 million.

5. Related Party Transactions

The Company leases two office buildings and a storage building from
its chief executive officer under a lease which provides for monthly
rentals of $27,618 plus the payment of all property taxes, insurance and
maintenance which are reported in the Company's consolidated financial
statements. The lease was renewed for a five year term on June 1, 2005
increasing the monthly rental from $24,969 to $27,618. In the opinion of
management, the rates paid are comparable to those that could be negotiated
with a third party.

The total minimum rental commitment under the building lease is as follows:


Year ending December 31:
2007 $ 331,415
2008 331,415
2009 331,415
2010 138,090
----------
$1,132,335
==========

Rent expense paid to the Company's chief executive officer totaled $331,415
for the year ended December 31, 2006, $318,169 and $299,625 for the years ended
December 31, 2005 and 2004 respectively. In 2005, the Company announced the
construction of a new corporate headquarters which is expected to be ready for
occupancy in 2007. The lease will be cancelled prior to the occupancy of the new
corporate headquarters and shop facility. The new facilities are being
constructed by the Company's chief executive officer and will be sold to the
Company for the cost of contruction.

During the first quarter of 2006, the Company purchased 16.7 acres of land
in North Liberty from the Company's chief executive officer for $1,250,000. The
purchase price was based on the fair market value that could be obtained from an
unrelated third party on an arm's length basis. The transaction was approved by
the Board of Directors.

6. Accident and Workers' Compensation Insurance Liabilities

The Company acts as a self-insurer for auto liability involving property
damage, personal injury, or cargo up to $1.0 million for any individual claim.
In addition, the Company is responsible for $2.0 million in the aggregate for
all claims in excess of $1.0 million and below $2.0 million. Liabilities in
excess of these amounts are assumed by an insurance company up to $50.0 million.
The Company increased the retention amount from $500,000 to $1.0 million for
each claim effective April 1, 2003.

The Company acts as a self-insurer for workers' compensation liability up
to $1.0 million for any individual claim. The Company increased the retention
amount from $500,000 to $1.0 million effective April 1, 2005. Liabilities in
excess of this amount are assumed by an insurance company. The State of Iowa has
required the Company to deposit $700,000 into a trust fund as part of the


29
self-insurance  program. This deposit has been classified in other assets on the
consolidated balance sheet. In addition, the Company has provided its insurance
carriers with letters of credit of approximately $2.5 million in connection with
its liability and workers' compensation insurance arrangements. There are no
outstanding balances due on the letters of credit at December 31, 2006.

Accident and workers' compensation accruals include the estimated
settlements, settlement expenses and an estimate for claims incurred but not yet
reported for property damage, personal injury and public liability losses from
vehicle accidents and cargo losses as well as workers' compensation claims for
amounts not covered by insurance.

Accident and workers' compensation accruals are based upon individual case
estimates, including reserve development, and estimates of
incurred-but-not-reported losses based upon past experience. Since the reported
liability is an estimate, the ultimate liability may be more or less than
reported. If adjustments to previously established accruals are required, such
amounts are included in operating expenses in the current period.

7. Stockholders' Equity

On July 21, 2004 the Board of Directors approved a three-for-two stock
split, affected in the form of a 50 percent stock dividend. The stock split
occurred on August 20, 2004, to shareholders of record as of August 9, 2004. A
total of 25.0 million common shares were issued in this transaction.

On April 20, 2006, the Board of Directors approved a four-for-three stock
split, affected in the form of a 33 percent stock dividend. The stock split
occurred on May 15, 2006, to shareholders of record as of May 5, 2006. This
stock split increased the number of outstanding shares to 98.4 million from 73.8
million. The number of common shares issued and outstanding and all per share
amounts have been adjusted to reflect the stock splits for all periods
presented.

In September, 2001, the Board of Directors of the Company authorized a
program to repurchase 6.3 million shares of the Company's Common Stock in open
market or negotiated transactions using available cash and cash equivalents. In
2006 and 2005, respectively, 176,700 and 1.2 million shares were repurchased and
retired. No shares were purchased during 2004. The authorization to repurchase
remains open at December 31, 2006 and has no expiration date.

On March 7, 2002, the principal stockholder awarded 181,500 shares of his
common stock to key employees of the Company. These shares had a fair market
value of $11.00 per share on the date of the award. The shares will vest over a
five-year period subject to restrictions on transferability and to forfeiture in
the event of termination of employment. Any forfeited shares will be returned to
the principal stockholder. The fair market value of these shares, $1,995,592 on
the date of the award, was treated as a contribution of capital and is being
amortized on a straight-line basis over the five year vesting period as
compensation expense. Compensation expense of approximately $376,000, $364,000,
and $380,000 was recognized for the years ended December 31, 2006, 2005, and
2004, respectively. The original value of forfeited shares is treated as a
reduction of additional paid in capital and unearned compensation in the
consolidated statements of shareholders' equity. There were no shares forfeited
during the year ended December 31, 2006. There were 2,000 shares forfeited in
2005 and no shares forfeited in 2004.

8. Profit Sharing Plan and Retirement Plan

The Company has a retirement savings plan (the "Plan") for substantially
all employees who have completed one year of service and are 19 years of age or
older. Employees may make 401(k) contributions subject to Internal Revenue Code
limitations. The Plan provides for a discretionary profit sharing contribution

information relating to the Company, including its consolidated subsidiaries, is
made known to the officers who certify the Company's financial reports and to
other members of senior management and the Board of Directors.

Based on their evaluation as of December 31, 2006, the principal executive
officer and principal financial officer of the Company have concluded that the
Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and
15d-15(e) under the Exchange Act) are effective to ensure that the information
required to be disclosed by the Company in the reports that it files or submits
under the Exchange Act is recorded, processed, summarized and reported within
the time periods specified in Securities and Exchange Commission (the "SEC")
rules and forms.

Management's Report on Internal Control Over Financial Reporting - The
Company's management is responsible for establishing and maintaining adequate
internal control over financial reporting, as such term is defined in Exchange
Act Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and
with the participation of our management, including our principal executive
officer and principal financial officer, we conducted an evaluation of the
effectiveness of our internal control over financial reporting based on the
framework in Internal Control - Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission as of December 31, 2006.
Based on our evaluation under the framework in Internal Control - Integrated
Framework, our management concluded that our internal control over financial
reporting was effective as of December 31, 2006. Our management's assessment of
the effectiveness of our internal control over financial reporting as of

Report of Independent Registered Public Accounting Firm



The Board of Directors and Stockholders
Heartland Express, Inc.:


We have audited management's assessment, included in the accompanying
Management's Report on Internal Control Over Financial Reporting under Item 9A,
that Heartland Express, Inc. and subsidiaries (the Company) maintained effective
internal control over financial reporting as of December 31, 2006, based on
criteria established in Internal Control--Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO). The
Company's management is responsible for maintaining effective internal control
over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting. Our responsibility is to express an opinion on
management's assessment and an opinion on the effectiveness of the Company's
internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over
financial reporting, evaluating management's assessment, testing and evaluating
the design and operating effectiveness of internal control, and performing such
other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.


A company's internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, management's assessment that Heartland Express, Inc. and
subsidiaries maintained effective internal control over financial reporting as
of December 31, 2006, is fairly stated, in all material respects, based on
criteria established in Internal Control--Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also,
in our opinion, the Company maintained, in all material respects, effective
internal control over financial reporting as of December 31, 2006, based on
criteria established in Internal Control--Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the consolidated balance
sheets of Heartland Express, Inc. and subsidiaries as of December 31, 2006 and
2005, and the related consolidated statements of income, stockholders' equity,
and cash flows for each of the years in the three-year period ended December 31,
2006, and our report dated February 27, 2007 expressed an unqualified opinion on
those consolidated financial statements.

By  execution  of this  written  instrument  (the "Basic  Plan  Document"),
Heartland Express, Inc. of Iowa establishes this Nonqualified Deferred
Compensation Plan ("Plan"), consisting of this Basic Plan Document, all of its
Exhibits and all other documents to which it refers, for the benefit of certain
Employees that the Employer designates as provided in this instrument. The
primary purpose of the Plan is to provide additional compensation to
Participants upon termination of employment or service with the Employer. The
Employer will pay benefits under the Plan only in accordance with the terms and
conditions set forth in the Plan.

PREAMBLE

Plan Type. The Employer establishes this Plan as an unfunded nonqualified

providing deferred compensation for a select group of management or highly
compensated employees" within the meaning of 29 U.S.C. Sections 1101(a)(1),
1081(a)(3) and 1051(2).

Possible Nonuniformity. The Plan terms set forth in this Plan Document
apply uniformly to all Participants; except to the extent the Employer adopts
inconsistent provisions with respect to one or more Participants in a separate
written instrument attached as an Addendum to this Basic Plan Document. The
Employer need not provide the same Plan benefits or apply the same Plan terms
and conditions to all Participants, even as to Participants who are of similar
pay, title and other status with the Employer. The Employer may create a
separate Addendum for one or more Participants, specifying such terms and
conditions as are applicable to a given Participant.

(B) Insignificant Service. If an Employee continues to perform services for
the Employer, but the services are not more than insignificant, the Employee

1.409A-1(m) or in Applicable Guidance.

identification date, the Participant is a Specified Employee for the 12 month
period commencing on the first day of the fourth month following the
identification date, which date is December 31. The Employer may amend its
Adoption Agreement to change the identification date but any such amendment is
not effective for 12 months after the adoption of the amendment. The Employer,
in determining whether this Section 1.43 and all related Plan provisions apply,
will determine whether the Employer has any publicly traded stock as of the date

amount pursuant to a nondiscretionary formula. For this purpose, the
Participant's or the Employer's designation of a calendar year or years for
payment without more is deemed to mean payment on January 1 in such years. A
Specified Time or Fixed Schedule also means as described in Prop. Treas. Reg.
Section 1.409A-3(g)(1) and other Applicable Guidance.

of forfeiture is substantial. A condition related to the purpose of the
Compensation relates to the Participant's performance for the Employer or to the
Employer's business activities or organizational goals. A Substantial Risk of
Forfeiture does not include any addition of a condition after a Legally Binding
Right to the Compensation arises or any extension of a period during which the
Compensation is subject to a Substantial Risk of Forfeiture. Compensation is not
subject to a Substantial Risk of Forfeiture merely because payment is
conditioned on the Participant's refraining from performing services.
Compensation is not subject to a Substantial Risk of forfeiture  beyond the date
or time that the Participant otherwise could have elected to receive the
Compensation unless the amount of Compensation (disregarding Earnings) is
materially greater than the amount of Compensation that the Participant
otherwise could have elected to receive. As such, a Participant's Elective
Deferrals generally may not be made subject to a Substantial Risk of Forfeiture.

Employees as designated by the Employer, from time to time, shall be
Participants in the Plan. An Employee shall be a Participant in this Plan only

Deferral election for that Taxable Year not later than 30 days after the
Plan goes into effect or the Participant becomes a Participant. The
election may apply only to Compensation for services the Participant
performs subsequent to the date the Participant delivers the election to
the Employer. For Compensation that is earned for a specified performance
period, including an annual bonus, and where the new Participant makes an
Elective Deferral election after the service period commences, the Employer
will pro rate the election by multiplying the Compensation by the ratio of
the number of days left in the performance period at the time of the
election, over the total number of days in the entire performance period.

(3) Omitted.

day of the Participant's Taxable Year, but is Compensation for the
Participant's services during the final payroll period within the meaning
of Code Section 3401(b) which contains the last day of the Taxable Year,
the Compensation is treated for purposes of an election under this Section
2.02(B), as Compensation for the current Taxable Year in which the final
payroll period commenced. This Section 2.02(B)(6) does not apply to
Compensation for services performed over any period other than the final
payroll period as described herein and the Employer will apply this Section
2.02(B)(6) in accordance with Prop. Treas. Reg. Section 1.409A-2(a)(11) and
Applicable Guidance. If the Employer amends its plan after December 31,
2006, to alter the timing rule of this Section 2.02(B)(6), any such
amendment may not take effect until 12 months after the later of the date
the amendment if adopted and is effective.

(7) Separation Pay/Window Program. If the Participant's election
relates to Separation Pay and the Separation Pay: (i) is due to an actual
involuntary Separation from Service; and (ii) is the result of bona-fide,
arm's length negotiations, then the Participant may make an election under
this Section 2.02(B) at any time up to the time that the Participant has a

Section 2.02(B) deadline becomes irrevocable as to a Taxable Year following the
last day on which a Participant may make an election under Section 2.02(B) for
such Taxable Year. A Participant may revoke or make any number of changes to
his/her Elective Deferral election during the period prior to the election
becoming irrevocable.
A change payment election under Section 4.03(B) does not
render an Elective Deferral election and an accompanying initial payment
election under Section 4.03(A), revocable within the meaning of this Section
2.02(C).

(D) Election Duration. A Participant's Elective Deferral election remains
in effect for the duration of the Taxable Year for which the Participant makes
the election and for all subsequent Taxable Years unless the Participant
executes a subsequent timely election, modification or revocation. A

those in Article VII, may make a new election, or may revoke or modify an
existing election effective no earlier than for the next Taxable Year.

2.03 Nonelective Contributions. During each Taxable Year the Employer may,
but is not required to, make one or more Nonelective Contributions to the Plan,
in such amounts as the Employer elects in its complete discretion, including
zero.

2.04 Omitted.

Taxable Year at such times as Code Section 409A or Applicable Guidance may
permit. The Employer is not required to contribute any actual contribution (or
to post any notional contribution) to an Account at the time that the Employer
makes its contribution election.

2.08 Administration. The Employer will administer all Employer
Contributions in the same manner as Elective Deferrals, except as the Plan
otherwise provides. Any Employer Contribution is not subject to an immediate
Participant right to elect a cash payment in lieu of the Employer Contribution
and such amounts are payable only in accordance with the Plan terms.

III. VESTING AND SUBSTANTIAL RISK OF FORFEITURE

3.01 Vesting Schedule or other Substantial Risk of Forfeiture.

(A) Elective Deferral Account. A Participant's Elective Deferral Account is
100% Vested at all times.

as of the Effective Date of a Participant's Nonelective Contribution
Account, plus Earnings credited thereto after the Effective Date, shall be
100% Vested at all times, subject to the terms of Section 3.01(B)(4).

(4) If at any time while the Participant is employed by the Employer
or has any balance in his/her Nonelective Contribution Account, the
Participant does any of the following, then the balance of such
Participant's Nonelective Contribution Account as of the date on which such
event occurs shall be entirely forfeited in the absolute discretion of the
Employer: (1) the Participant directly or indirectly competes against the
Employer or directly or indirectly assists a third party in competing

the Employer an act of fraud, misappropriation or embezzlement.

3.02 Immediate Vesting on Specified Events. Notwithstanding Sections

Vested without regard to the Participant's age or credited Years of Service if
the Participant incurs a Separation from Service as a result of (1) the
Participant's death, (2) the Participant's Disability, or (3) a Change in
Control. For purposes of the immediately preceding sentence, a Participant shall
only be deemed to have incurred a Separation from Service as the result of a
Change in Control if both of the following conditions (1) and (2) are satisfied
and either one of the following conditions (3) or (4) are satisfied: (1) the
Participant's Account is not forfeited pursuant to section 3.01(B)(3), (2) the
Separation from Service occurs within nine (9) months of the Change in Control,
(3) the Separation from Service is not voluntary by the Participant, and (4) the

Control.

4.01 Payment Events. A Participant's Vested Accrued Benefit may not be paid
to the Participant until after the earlier of the following events to occur: (1)
the Participant's Separation from Service; and (2) the Participant attaining
Retirement Age. Following the occurrence of any of the forgoing events, the Plan
will pay to the Participant (or if the Participant is deceased, the
Participant's Beneficiary) the Vested Accrued Benefit held in the Participant's
Account at the time and in the form and method determined in accordance with the
Employer and Participant's respective elections under Section 4.03.

(A) Payment to Specified Employees. Notwithstanding anything to the
contrary in the Plan or in a Participant or Employer payment election, the Plan
may not make payment to a Specified Employee, based on Separation from Service,
earlier than 6 months following Separation from Service (or if earlier, upon the
Specified Employee's death), except as permitted in the final sentence of this
Section 4.01(A). Any payments that otherwise would be payable to the Specified
Employee during the foregoing 6 month period will be accumulated and payment
delayed until a date specified in the Adoption Agreement that is after the 6
month period. The Employer may amend this Section 4.01 with regard to the method
of treating payments otherwise payable within the 6 month period, provided that
any change in method may not be effective for 12 months after the adoption of
the amendment. This Section 4.01(A) does not apply to payments made on account
of a domestic relations order under Section 4.03(D)(i), payments made because of
a conflict of interest under Section 4.03(D)(ii), or payment of employment taxes
under Section 4.03(D)(v).

4.02 Omitted.

4.03 Form, Timing and Method/ Payment Election. The Plan will pay a
Participant's Vested Accrued Benefit from his/her Elective Deferral Account in
the method (as between lump-sum and installments) and commencing as of the date
determined in accordance with the Participant's election under Sections 4.03(A)
or (B). Likewise, the Plan will pay a Participant's Vested Accrued Benefit from
his/her Nonelective Deferral Account in the method (as between lump-sum and
installments) and commencing as of the date determined in accordance with the
Employer's election under Sections 4.03(A) or (B). Until the Plan pays a
Participant's entire Vested Accrued Benefit, the Plan will continue to credit
the Participant's Account with Earnings, in accordance with Section 5.02. The
Plan will pay a Participant's Vested Accrued Benefit in the form (as between
property and cash) determined by Employer in its discretion. Notwithstanding any
payment election by Participant to the contrary, upon the Participant's death,
the Employer shall pay as soon as administratively permissible in lump sum any
Vested Accrued Benefit remaining in the Participant's Account at death to the
applicable person or persons determined in accordance with Section 4.05.

(A) Initial Payment Election. A Participant must make an initial payment
election with respect to his/her Elective Deferral Account at the time of the
Participant's Elective Deferral election under Section 2.02(B). The Employer
must make an initial payment election as to a Participant's Nonelective Deferral
Account at the time that the Employer grants a Legally Binding Right to Deferred
Compensation to the Participant. A payment election may apply only to the
Deferred Compensation that is the subject of the Elective Deferral election or
the Employer Contribution or may apply to such Deferred Compensation and to all
future Deferred Compensation, as the payment election indicates. A Participant
must make any permissible initial payment election on a form the Employer
provides for that purpose. If the Participant or the Employer as applicable have
the right to make an initial payment election but fail to do so, the Plan will
pay the affected Participant's Vested Accrued Benefit attributable to the
non-election under this default provision, in a lump-sum cash payment 13 months
following the earliest event permitting payment of the Participant's Account
under Section 4.01. If this default provision applies, the default payment is
deemed to be an initial payment election under the Plan.

(B) Change Payment Election. A Participant's and the Employer's initial
payment election under Section 4.03(A) (including any Plan default payment
applicable in the absence of an actual initial payment election) may be
subsequently changed in the manner provided in this Section 4.03(B). Further, a
Beneficiary following a Participant's death may make a change payment election
under this Section 4.03(B) with respect to the deceased Participant's Elective
Deferral Account. A Participant or Beneficiary must make any change payment
election on a form the Employer provides for such purpose.

(1) Conditions on Change Payment Elections. Any Participant or
Employer change payment election: (i) may not take effect until at least 12
months following the date of the change payment election; (ii) if the
change payment election relates to a payment based on Separation from
Service or on Change in Control, or if the payment is at a Specified Time
or pursuant to a Fixed Schedule, the change payment election must result in
payment being made not earlier than 5 years following the date upon which
the payment otherwise would
have been made (or,  in the case of an  installment  payments  treated as a
single payment, 5 years from the date the first amount was scheduled to be
paid); and (iii) if the change payment election relates to payment at a
Specified Time or pursuant to a Fixed Schedule, the Participant or Employer
must make the change payment election not less than 12 months prior to the
date the payment is scheduled to be made (or, in the case of an installment
payments treated as a single payment, 12 months prior to the date the first
amount was scheduled to be paid).

(2) Definition of "Payment." Except as otherwise provided in Section
4.03(B)(3), a "payment" for purposes of applying Section 4.03(B)(1) is each
separately identified amount the Plan is obligated to pay to a Participant
on a determinable date and includes amounts paid for the benefit of the
Participant. An amount is "separately identified" only if the Employer can
objectively determine the amount. A payment includes the provision of any
taxable benefit, including payment in cash or in-kind. A payment includes,
but is not limited to, the transfer, cancellation or reduction of an amount
of Deferred Compensation in exchange for benefits under a welfare benefit
plan, fringe benefits excludible under Code Sec 119 or Sec 132, or any
other benefit that is excluded from gross income.

(3) Installment Payments. For purposes of Section 4.03, a series of
installment payments is treated as a single payment. For purposes of this
Section 4.03(B)(3), a "series of installment payments" means payment of a
series of substantially equal periodic amounts to be paid over a
predetermined number of years, except to the extent that any increase in
the payment amounts reflects reasonable Earnings through the date of
payment.

(4) Coordination with Anti-Acceleration Rule. In applying Section
4.03(C), "payment" means as described in Sections 4.03(B)(2) and (3). A
Participant under a change payment election may change the form of payment
to a more rapid schedule (including a change from installments to a
lump-sum payment) without violating Section 4.03(C), provided any such
change remains subject to the change payment election provisions under this
Section 4.03(B). Accordingly, if the Participant's payment change election
modifies the payment method from installments to a lump-sum payment, a
change payment election must satisfy Section 4.03(B)(1) measured from the
first installment payment. If a change payment election only modifies the
timing of an installment payment, the change payment election must apply to
each installment and must satisfy Section 4.03(B) measured from each
installment payment.

(5) Omitted.

(6) Certain Payment Delays not Subject to Change Payment Election
Rules. The following payment delay provisions do not result in the Plan
failing to provide for payment upon a permissible event as Code Sec 409A
requires nor are the delays treated as a change payment election under this
Section 4.03(B). The Plan, in the Employer's complete discretion, may delay
payment to a Participant if the Employer reasonably anticipates that the
payment will violate Federal securities law or other applicable law. The
Plan will pay such Deferred Compensation at the earliest date at which the
Employer reasonably anticipates that the payment will not cause a violation
of such laws. For purposes of this Section 4.03(B)(6), a violation of
"other applicable law" does not include a payment which would cause
inclusion of the Deferred Compensation in the Participant's gross income or
which would subject the Participant to any Code penalty or other Code
provision. If the Employer amends this Section 4.03(B)(6) to add any
additional payment delays permitted under Applicable Guidance, then any
such amendment may not be effective for at least 12 months following the
Employer's adoption of the amendment. As required under Section 4.03(C),
the Employer may not amend this Section 4.03(B)(6) to remove any or all
payment delays described herein as to any previous Deferred Compensation.

(C) No Acceleration-General Rule. Neither the Employer nor a Participant
may accelerate the time or schedule of any Plan payment or amount scheduled to
be paid under the Plan. For this purpose, the following are not an acceleration:
(i) payment made in accordance with Plan provisions or pursuant to an initial
payment election under Section 4.03(A) or a change payment election under
Section 4.03(B) under which payment on an accelerated schedule is required on
account of an intervening event which includes Separation from Service,
Disability, death, Change in Control or Unforeseeable Emergency; (ii) The
Employer's waiver or acceleration of the satisfaction of any condition
constituting a Substantial Risk of Forfeiture provided that payment is made only
upon a permissible payment event and the Employer's action otherwise does not
violate Code Sec 409A; and (iii) a choice between a distribution of cash or
property if the timing and the amount of income inclusion to the Participant are
the same.
(D)  Permissible   Accelerations.   Notwithstanding  Section  4.03(C),  the
following accelerations of the time or schedule of payment are permitted with
regard to the payment of each Participant's Account: (i) a payment to an
individual other than the Participant required under a domestic relations order
under Code Sec. 414(p)(1)(B); (ii) a payment required under a certificate of
divestiture under Code Sec. 1043(b)(2) relating to conflicts of interest; (iii)
a Plan amendment to permit certain cash-out payments described in Sections
4.03(E) and (F); (iv) as it relates to the Deferred Compensation, a payment to
pay the FICA tax under Code Sec 3101, 3121(a) and 3121(v)(2) and to pay income
taxes at source on wages under Code Sec 3401 or under corresponding provisions
of state, local or foreign tax laws related to payment of the FICA and to pay
additional income tax at source on wages attributable to pyramiding Section Sec
3401 wages and taxes, but the total of all such payments may not exceed the
aggregate of the FICA amount and the income tax withholding related to the FICA
amount; (v) a payment to any affected Participant at any time that the Plan
fails to meet the requirements of Code Sec 409A and the regulations thereunder,
provided that such payment may not exceed the amount required to be included in
income as a result of such failure; and (vi) payment to prevent the occurrence
of a "nonallocation year" under Code Sec 409(p) in accordance with Prop. Treas.
Reg. Sec 1.409A-3(h)(2)(ix) or other Applicable Guidance.

(E) Cash-Out Upon Separation. Notwithstanding a Participant's or the
Employer's payment election, the Plan will pay in a single cash payment the
entire Vested Accrued Benefit of a Participant who has Separated from Service
where the Participant's Vested Accrued Benefit does not exceed $10,000. A
payment under this Section 4.03(E) must terminate the Participant's entire
interest in the Plan and in all similar deferred compensation arrangements
within the meaning of Prop. Treas. Reg. Sec 1.409A-1(c) or other Applicable
Guidance. The Employer will make any payment under this Section 4.03(E) on or
before the later of: (i) December 31 of the Taxable Year in which the
Participant Separates from Service; or (ii) the 15th day of the third month
following the Participant's Separation from Service.

(F) Omitted.

4.04 Withholding. The Employer will withhold from any payment made under
the Plan and from any amount taxable under Code Sec 409A, all applicable taxes,
and any and all other amounts required to be withheld under Federal, state or
local law, including Notice 2005-1 and other Applicable Guidance.

4.05 Beneficiary Designation. A Participant may designate a Beneficiary
(including one or more primary and contingent Beneficiaries) to receive payment
of any Vested Accrued Benefit remaining in the Participant's Account at death.
The Employer will provide each Participant with a form for this purpose and no
designation will be effective unless made on that form and delivered to the
Employer. A Participant may modify or revoke an existing designation of
Beneficiary by executing and delivering a new designation to the Employer. In
the absence of a properly designated Beneficiary, the Employer will pay a
deceased Participant's Vested Accrued Benefit to the Participant's surviving
spouse and if none, to the duly appointed personal representative of the
Participant's estate. If a Beneficiary is a minor or otherwise is a person whom
the Employer reasonably determines to be legally incompetent, the Employer may
cause the Plan to pay the Participant's Vested Accrued Benefit to a guardian,
trustee or other proper legal representative of the Beneficiary. The Plan's
payment of the deceased Participant's Vested Accrued Benefit to the person or
persons determined in accordance with the preceding provisions of this Section
4.05 shall completely discharge the Employer and the Plan of all further
obligations under the Plan.

4.06 Administration of Payment Date(s).

(A) Objective Payment Date(s). The Participant or the Employer in an
initial payment election or change payment election made pursuant to the
Adoption Agreement must provide for a payment date that the Employer, at the
time of the payment event, objectively can determine. Such payment date may, but
need not, coincide with a payment event, but any payment must be on or following
and must relate to a Plan payment event. If any such election provides for
payment only in a designated calendar year, the payment date is deemed to be
January 1 of that year.

(B) Multiple Payment Events/Fixed Schedule Linked to Payment Events. The
Participant or the Employer in a payment election under Sections 4.03(A) or (B):
(i) may  provide  for  payment  upon the  earliest  or  latest  of more than one
permissible payment event under Sections 4.01 and 4.02; (ii) may provide that a
payment based on Separation from Service, attaining Retirement Age, death, or
Change in Control is to be made in accordance with a Fixed Schedule that the
Employer objectively can determine at the time of the applicable payment event;
or (iii) may provide for an alternative payment schedule if the payment event to
which the payment schedule is linked occurs prior to a single specified date.

(C) Treatment of Payment as Made on Designated Payment Date. The Plan's
payment of Deferred Compensation is deemed made on the Plan required payment
date or payment election required payment date even if the Plan makes payment
after such date, provided the payment is made by the latest of: (i) the end of
the calendar year in which the payment is due; (ii) the 15th day of the third
calendar month following the payment due date; (iii) in case the Employer cannot
calculate the payment amount on account of administrative impracticality which
is beyond the Participant's control (or the control of the Participant's
estate), in the first calendar year in which payment is practicable; (iv) in
case the Employer does not have sufficient funds to make the payment without
jeopardizing the Employer's solvency, in the first calendar year in which the
Employer's funds are sufficient to make the payment. The Employer may cause the
Plan to pay a Participant's Vested Accrued Benefit on any date which satisfies
this Section 4.06(C) and that is administratively practicable following any Plan
specified payment date or the date specified in any valid payment election.

(D) Disputed Payments. In the event of a dispute between the Employer and a
Participant as to whether Deferred Compensation is payable to the Participant or
as to the amount thereof, the Plan is deemed to make timely payment on any Plan
required payment date or payment election required payment date if: (i) the
Participant accepts any portion of the payment that the Employer is willing to
make (unless such acceptance results in a forfeiture of the Participant's claim
to the remaining amount); (ii) the Participant makes prompt, reasonable and
good-faith efforts to collect the payment; and (iii) the Plan makes payment in
the first calendar year in which the Employer and the Participant enter into a
legally binding settlement of the dispute, the Employer concedes that the amount
is payable or the Employer is required to cause the Plan to make payment under a
final and nonappealable judgment or other binding decision. This Section 4.06(D)
does not apply if the Plan's failure to make payment on a required date is on
account of: (i) the Participant's failure to request payment, to provide
information or to take any other action necessary for the Plan to make payment;
or (ii) the Participant or a member of the Participant's family (as defined in
Code Sec 267(c)(4) applied to include the spouse of any family member), any
person or group of persons over whom the Participant or the Participant's family
has effective control or any person whose compensation (or any portion thereof)
is controlled by the Participant or the Participant's family members, makes the
decision to not pay.

4.07 Employer Approval of Participant Elections. A Participant's or the
Employer's initial payment elections or change payment elections must be
consistent with the Plan and with the Adoption Agreement. The Employer at the
time of the election must approve any Participant payment election as to form,
timing and method, where the Adoption Agreement does not expressly authorize the
elected form, timing or method. The Employer, in its absolute discretion, may
withhold approval for any reason, including, but not limited to non-compliance
with Plan terms. If the Employer does not approve a Participant's initial
payment election or change payment election, the Employer will pay the
Participant's Vested Accrued Benefit under Section 4.03 as though the
Participant did not make such payment election.

V. PLAN EARNINGS

5.01 Unfunded Plan. The Employer intends this Plan to be an unfunded plan
that is wholly or partially exempt under ERISA. No Participant, Beneficiary or
successor thereto has any legal or equitable right, interest or claim to any
property or assets of the Employer, including assets held in any Account under
the Plan. The Employer's obligation to pay Plan benefits is an unsecured promise
to pay. This Plan does not create a trust for the benefit of any Participant. At
any time the Employer may amend this Plan such that (i) the Employer may elect
to make notional contributions in lieu of actual contributions to the Plan; and
(ii) the Employer may elect not to invest any actual Plan contributions. If the
Employer elects to invest any actual Plan contributions, such investments may be
held for the Employer's benefit in providing for the Employer's obligations
under the Plan or for such other purposes as the Employer may determine. Any
assets held in Plan Accounts remain subject to claims of the Employer's general
creditors, and no Participant's or Beneficiary's claim to Plan assets has any
priority over any general unsecured creditor of the Employer.
5.02 Account Earnings. The Plan periodically will credit each Participant's
Elective Deferral and Nonelective Contribution as actual contributions to that
Participant's Account. Further, the Plan periodically will credit or charge each
Participant's Account with net investment earnings, gain and loss actually
incurred by the Account. The Participant has the right to direct the investment
of the Participant's Account, subject to the Employer's discretionary right to
limit the investment options available to the Participant and the Employer's
discretionary control over the mechanics and methodology for executing such
investment direction by the Participant. The Participant's right to direct the
investment of his/her Account is limited strictly to investment direction, and
the Participant will not be entitled to the distribution of any Account asset
except as the Plan otherwise permits. If a Participant fails at any time to
direct the investment of his/her Account, pursuant to investment elections that
may be required from time to time at the inception of such Account or
subsequently thereto, then the Employer shall have the right in its absolute
discretion to direct the investment of such Account, and such investment
direction by the Employer shall be exempt from any prudent investor, risk
diversification or other investment standards that might otherwise be
applicable. Except as otherwise provided in the Plan, all Plan assets, including
all incidents of ownership thereto, at all times will be the sole property of
the Employer.

VI. MISCELLANEOUS

6.01 No Assignment. No Participant or Beneficiary has the right to
anticipate, alienate, assign, pledge, encumber, sell, transfer, mortgage or
otherwise in any manner convey in advance of actual receipt, the Participant's
Account. Prior to actual payment, a Participant's Account is not subject to the
debts, judgments or other obligations of the Participant or Beneficiary and is
not subject to attachment, seizure, garnishment or other process applicable to
the Participant or Beneficiary.

6.02 Not Employment Contract. This Plan is not a contract for employment
between the Employer and any Employee who is a Participant. This Plan does not
entitle any Participant to continued employment with the Employer, and benefits
under the Plan are limited to payment of a Participant's Vested Accrued Benefit
in accordance with the terms of the Plan.

6.03 Amendment and Termination.

(A) Amendment.

(1) Amendment and Restatement of Prior Plans and Arrangements. This
Basic Plan Document is hereby deemed an amendment and restatement of any
and all prior nonqualified deferred compensation top hat plans or
arrangements previously sponsored by the Employer, the terms of which are
hereby superseded and replaced. Each Participant's benefits and interests
under any and all prior nonqualified deferred compensation top hat plans
and arrangements, if any, are now solely represented by such Participant's
Accrued Benefit.

(2) Future Plan Amendments. The Employer reserves the right to amend
the Plan at any time to comply with Code Sec 409A, Notice 2005-1, Prop.
Treas. Reg. Sec 1.409A and other Applicable Guidance or for any other
purpose, provided that such amendment will not result in taxation to any
Participant under Code Sec 409A. Except as the Plan and Applicable Guidance
otherwise may require, the Employer may make any such amendments effective
immediately.

(B) Termination. The Employer may terminate, but is not required to
terminate, the Plan and distribute Plan Accounts under the following
circumstances:

(1) Dissolution/Bankruptcy. The Employer may terminate the Plan within
12 months following a dissolution of a corporate Employer taxable under
Code Sec 331 or with approval of a Bankruptcy court under 11 U.S.C. Sec
503(b)(1)(A), provided that the Deferred Compensation is paid to the
Participants and is included in the Participants' gross income in the
latest calendar year: (i) in which the plan termination occurs; (ii) in
which the amounts no longer are subject to a Substantial Risk of
Forfeiture; or (iii) in which the payment is administratively practicable.
(2) Change in Control.  The Employer may terminate the Plan within the
30 days preceding or the 12 months following a Change in Control provided
the Employer distributes all Plan Accounts (and must distribute the
accounts under any substantially similar Employer plan which plan the
Employer also must terminate) within 12 months following the Plan
termination.

(3) Other. The Employer may terminate the Plan for any other reason in
the Employer's discretion provided that: (i) the Employer also terminates
all Aggregated Plans in which any Participant also is a participant; (ii)
the Plan makes no payments in the 12 months following the Plan termination
date other than payments the Plan would have made irrespective of Plan
termination; (iii) the Plan makes all payments within 24 months following
the Plan termination date; and (iv) the Employer within 5 years following
the Plan termination date does not adopt a new plan covering any
Participant that would be an Aggregated Plan.

(4) Applicable Guidance. The Employer may terminate the Plan under
such other circumstances as Applicable Guidance may permit.

(C) Effect on Vesting. Any Plan amendment or termination will not reduce
the Vested Accrued Benefit held in any Participant Account at the date of the
amendment or termination and also may not accelerate vesting except as may be
permitted without subjecting any Participant to taxation under Code Sec 409A.

(D) Cessation of Future Contributions. The Employer may elect at any time
to amend the Plan to cease future Elective Deferrals or Nonelective
Contributions as of a specified date. In such event, the Plan remains in effect
(except those provisions permitting the frozen contribution type) until all
Accounts are paid in accordance with the Plan terms, or, if earlier, upon the
Employer's termination of the Plan.

6.04 Severability. If the Employer or any proper authority determines any
provision of the Plan will cause taxation under Code Sec 409A or is otherwise
invalid, the remaining portions of the Plan will continue in effect and will be
interpreted consistent with the elimination of the invalid provision.

6.05 Notice and Elections. Any notice given or election made under the Plan
must be in writing and must be delivered or mailed by certified mail, to the
Employer or to the Participant or Beneficiary as appropriate. The Employer will
prescribe the form of any Plan notice or election to be given to or made by
Participants. Any notice or election will be deemed given or made as of the date
of delivery, or if given or made by certified mail, as of 3 business days after
mailing.

6.06 Administration. The Employer will administer and interpret the Plan,
including making a determination of the Vested Accrued Benefit due any
Participant or Beneficiary under the Plan. As a condition of receiving any Plan
benefit to which a Participant or Beneficiary otherwise may be entitled, a
Participant or Beneficiary will provide such information and will perform such
other acts as the Employer reasonably may request. The Employer may cause the
Plan to forfeit any or all of a Participant's Vested Accrued Benefit, if the
Participant fails to cooperate reasonably with the Employer in the
administration of the Participant's Plan Account, provided that this provision
does not apply to a bona fide dispute under Section 4.06(D). The Employer may
retain agents to assist in the administration of the Plan and may delegate to
agents such duties as it sees fit. The decision of the Employer or its designee
concerning the administration of the Plan is final and is binding upon all
persons having any interest in the Plan. The Employer will indemnify, defend and
hold harmless any Employee designated by the Employer to assist in the
administration of the Plan from any and all loss, damage, claims, expense or
liability with respect to this Plan (collectively, "claims") except claims
arising from the intentional acts or gross negligence of the Employee.

6.07 Account Statements. The Employer from time to time will provide each
Participant with a statement of the Participant's Vested Accrued Benefit. The
Employer also will provide Account statements to any Beneficiary of a deceased
Participant with a Vested Accrued Benefit remaining in the Plan.

6.08 Accounting. The Employer will maintain for each Participant as is
necessary for proper administration of the Plan, an Elective Deferral Account
and a Nonelective Contribution Account.
6.09 Costs and Expenses. Except for investment charges, which will be borne
by the Account to which they pertain, the Employer will pay the costs, expenses
and fees associated with the operation of the Plan, excluding those incurred by
Participants or Beneficiaries.

6.10 Reporting. The Employer will report Deferred Compensation for Employee
Participants on Form W-2 for Employee Participants in accordance with Notice
2005-1 and Applicable Guidance.

6.11 ERISA Claims Procedure. Subject to the following, the claims
procedures set forth in DOL Reg. Sec 2560.503-1 apply as the Plan's claims
procedures: For purposes of the Plan's claims procedure under this Section 6.11,
the "Plan Administrator" means the Employer. A Participant or Beneficiary may
file with the Plan Administrator a written claim for benefits, if the
Participant or Beneficiary disputes the Plan Administrator's determination
regarding the Participant's or Beneficiary's Plan benefit. However, the Plan
Administrator will cause the Plan to pay only such benefits as the Plan
Administrator in its discretion determines a Participant or Beneficiary is
entitled to receive. The Plan Administrator under this Section 6.11 will provide
a separate written document to affected Participants and Beneficiaries which
explains the Plan's claims procedure and which by this reference is incorporated
into the Plan. If the Plan Administrator makes a final written determination
denying a Participant's or Beneficiary's claim, the Participant or Beneficiary
must file an action with respect to the denied claim within 180 days following
the date of the Plan Administrator's final determination.

VII. APPLICABLE 409A TRANSITION RULES

7.01 2005 and 2006 Operational Rules. The following provisions apply to the
Plan during the 2005 and 2006 Taxable Years.

(A) Good Faith. The Employer will operate the Plan during the 2005 and 2006
Taxable Years in good faith compliance in accordance with: (i) Notice 2005-1;
(ii) Code Sec 409A; and (iii) any Applicable Guidance as of the effective date
thereof. The Employer also may operate the Plan consistent with the Prop. Treas.
Reg. Sec 1.409A before such regulations become effective and may apply such
regulations to the extent that they are inconsistent with Notice 2005-1.
Although the Employer intends this Plan document to comply with the provisions
of Notice 2005-1 and of Prop. Treas. Reg. Sec 1.409A, the Employer will not
apply any Plan provision which is inconsistent therewith and, by December 31,
2006, will amend any such provision to comply with Applicable Guidance. The
Employer and the Participants may not exercise discretion under the Plan in a
manner that would violate Code Sec 409A.

(B) New Payment Elections. A Participant, on or before December 31, 2006,
may make a new payment election as to any Compensation Deferred previously. Any
such election must be a permissible election under Section 4.03(A), but an
election under this Section 7.01(B) is not treated as a change in the timing or
form of distribution and need not comply with Section 4.03(B) as it applies to
such changes. In addition, during 2006, a Participant may not make a new payment
election under this Section 7.01(B) which: (i) would result in the Participant
not receiving any payment which the Plan otherwise would make in 2006; or (ii)
would accelerate to 2006 any payment the Plan would otherwise make after 2006.

7.02 Incorporation of Applicable Guidance. In the event of Applicable
Guidance that is contrary to any Plan provision, the Employer, as of the
effective date of the Applicable Guidance, will operate the Plan in conformance
therewith and disregard any inconsistent Plan provision. Any such Applicable
Guidance is deemed to be incorporated by reference into the Plan and to
supersede any contrary Plan provision during any period in which the Employer is
permitted to comply operationally with the Applicable Guidance and before a
formal Plan amendment is required.

2006 Top Hat Nonqualified Deferred Compensation Plan
ERISA Claims Procedure

Pursuant to section 6.11 of the 2006 Top Hat Nonqualified Deferred Compensation
Plan, the following claims procedures shall apply to and are hereby incorporated
into the Plan with respect to any claim for benefits under the Plan by a
Participant or Beneficiary. All capitalized terms used in this instrument shall
have the definition set forth in the Plan unless expressly provided otherwise in
this instrument.

1. NAMED FIDUCIARY AND PLAN ADMINISTRATOR. The Named Fiduciary and Plan
Administrator of the Plan shall be the Employer (Heartland Express, Inc. of
Iowa) until its resignation or removal by the Employer's board of
directors. The Named Fiduciary and Administrator shall be responsible for
management, control and administration of the Plan as established herein
and shall make all determinations as to rights to benefits under the Plan.
It may delegate to others certain aspects of the management and operation
responsibilities of the Plan including the employment of advisors and the
delegation of ministerial duties to qualified individuals.

2. FILING OF CLAIM FOR BENEFITS. A Participant or Beneficiary of the Plan
shall make a claim for the benefits by delivering a written request to the
Plan Administrator or such person or office as the Plan Administrator shall
designate for the processing of claims. Upon receipt of such request, the
Plan Administrator may require the claimant to complete such forms and
provide such additional information as may be reasonably necessary to
establish the claimant's right to the benefit under the Plan.
3. NOTIFICATION TO CLAIMANT OF DECISION. If a claim for benefits is wholly or
partially denied, the Plan Administrator (or the party to whom such
authority has been delegated) shall furnish to claimant a notice of the
decision, meeting the requirement of the following Paragraph 4, within
ninety (90) days after receipt of the claim by the Plan Administrator. If
special circumstances require more than ninety (90) days to process the
claim, this period may be extended for up to an additional ninety (90) days
by giving written notice to the claimant before the end of the initial
ninety (90) day period. However, if the claim for benefits concerns the
payment of benefits under the Plan due to a determination of Employee as
disabled, then a decision shall be rendered within 45, not 90, days, and
such period may be extended, if special circumstances require such an
extension, by no more than two 30-day periods by giving written notice to
the claimant of such extensions. An extension notice shall indicate (1) the
special circumstances requiring an extension of time, (2) the date by which
the Corporation expects to render the benefit determination, (3) the
standards on which entitlement to a benefit is based, (4) the unresolved
issues that prevent a decision on the claim, and (5) the additional
information needed to resolve those issues. If the period of time is
extended because the claimant has failed to provide necessary information
to decide the claim, the claimant shall have at least 45 days within which
to provide the specified information, and the period for making the benefit
determination shall be tolled from the date on which the notification of
the extension is sent to the claimant, until the date on which the claimant
provides the information. Failure to provide a notice of decision in the
time specified shall constitute a denial of the claim and the claimant
shall be entitled to require a review of the denial under the review
procedures specified in Paragraphs 5 and 6 below.

4. CONTENT OF NOTICE. The notice to be provided to every claimant who is
denied a claim for benefits under Paragraph 3 above shall be in writing and
shall set forth in a manner calculated to be understood by the claimant,
the following:

a. The specific reason or reasons for the denial;

b. A specific reference to pertinent Plan provisions on which the denial is
based;
c.   A description of any additional  material or information  necessary for the
claimant to perfect the claim and the explanation of why such material or
information is necessary; and

d. An explanation of the Plan's claim review procedure describing the steps to
be taken by the claimant who wishes to submit his or her claim for review
and including a statement of the claimant's rights to bring a civil action
under Section 502 of ERISA following an adverse determination in review,
all written in a manner calculated to be understood by the claimant.

5. REVIEW PROCEDURE. The purpose of the review procedure set forth in this
paragraph and in Paragraph 6 following is to provide a procedure by which a
claimant under the Plan may have a reasonable opportunity to appeal a
denial of a claim to an "appropriate named fiduciary" for a full and fair
review. As used herein, the term "appropriate name fiduciary" shall mean
the Employer. To accomplish this purpose, the claimant or his duly
authorized representative:

a. May request a review upon written application to the appropriate name
fiduciary;

b. May Review pertinent Plan documents; and

c. May submit issues and comments in writing.

A claimant (or his duly authorized representative) shall request a review by
filing a written application for the review with the appropriate named fiduciary
at any time within sixty (60) days after receipt by the claimant of written
notice of the denial of his claim. However, if the claim for benefits concerns
the payment of benefits under the Plan due to a determination of Employee as
disabled, then a claimant shall have 180, not 60, days to file a written
application for review.

6. DECISION ON REVIEW. The decision on review of a denied claim shall be made
in the following manner.

a. The decision on review shall be made by the appropriate named fiduciary
that may, in his or its discretion, hold a hearing on the denied claim. The
appropriate named fiduciary shall make his or its decision promptly which
shall ordinarily be not later than sixty (60) days after the Plan's receipt
of the request for review unless special circumstances (such as the need
for holding a hearing) require an extension of time for processing. In that
case a decision shall be rendered as soon as possible, but not later than
one hundred twenty (120) days after receipt of the request for review.
However, if the claim for benefits concerns the payment of benefits under
the Plan due to a determination of Employee as disabled, then a decision on
appeal shall be rendered within 45, not 60, days; provided that an
extension due to special circumstance for an additional 45 days is
permitted. If an extension of time is required due to special
circumstances, written notice of the extension shall be furnished to the
claimant prior to the time the extension commences containing the same
information as stated in paragraph 3 of this Schedule "1" with regard to an
extension of the initial review.

b. The decision on review shall be in writing and shall include (1) specific
reasons for the decisions, written in a manner calculated to be understood
by the claimant, (2) specific references to the pertinent Plan provisions
on which the decision is based, (3) a statement that the claimant is
entitled to receive, upon request and free of charge, reasonable access to,
and copies of, all documents, records and other information relevant to the
claimant's claim for benefits; and (4) a statement of claimant's right to
bring an action under Section 502(a) of ERISA, all written in a manner
calculated to be understood by the claimant..

c. In the event the decision on review is not furnished to the claimant within
the time required, the claim shall be deemed denied on review.
