                                        PART I

ITEM 1.   BUSINESS

     (a)  GENERAL DEVELOPMENT OF BUSINESS.

      Marten Transport, Ltd. is a long-haul truckload carrier providing
protective service and time-sensitive transportation.  "Protective service
transportation" means temperature controlled or insulated carriage of
temperature-sensitive materials and general commodities.  We have operating
authority, both contract and common, granted by the Interstate Commerce
Commission ("ICC") and are currently regulated by the United States Department
of Transportation ("DOT") and the Federal Highway Administration ("FHWA").

      As of December 31, 1998, we operated a fleet of 1,460 tractors and 2,097
trailers.  Most of our trailers are protective service trailers.  As of December
31, 1998, 994 tractors and 2,094 trailers in our fleet were company-owned and
466 tractors and 3 trailers were under contract with independent contractors. 
As of December 31, 1998, we had 1,337 employees, including 1,026 drivers.  Our
employees are not represented by a collective bargaining unit. 

      Organized under Wisconsin law in 1970, we are a successor to a sole
proprietorship Roger R. Marten founded in 1946.  In 1988, we reincorporated
under Delaware law.  Our executive offices are located at 129 Marten Street,
Mondovi, Wisconsin 54755.  Our telephone number is (715) 926-4216. 

     (b)  FINANCIAL INFORMATION ABOUT SEGMENTS.

      Since our inception, substantially all of our revenue, operating profits
and assets have related primarily to one business segment--long-haul truckload
carriage of time- and temperature-sensitive materials and general commodities. 

     (c)  NARRATIVE DESCRIPTION OF BUSINESS.

      We specialize in protective service transportation of foods, chemicals and
other products requiring temperature-controlled carriage or insulated carriage. 
We also provide dry freight carriage.  In 1998, we earned approximately 79% of
our revenue from hauling protective service products and 21% of our revenue from
hauling dry freight.  Most of our dry freight loads require the special services
we offer or allow us to position our equipment for hauling protective service
loads.  The specialized transportation services we offer include: 

     -    dependable, late-model tractors allowing timely deliveries;

     -    late-model, temperature controlled trailers;

     -    scheduled pickups and deliveries;
<PAGE>

     -    assistance in loading and unloading;

     -    availability of extra trailers placed for customers' convenience;

     -    sufficient equipment to respond promptly to customers' varying needs;
          and

     -    an on-line computer system, which customers use to obtain information
          on the status of deliveries.

MARKETING AND CUSTOMERS

      Our senior management and marketing personnel seek customers whose
products require protective or other specialized services and who ship multiple
truckloads per week.  To minimize empty miles, we also solicit customers whose
shipping requirements allow us to balance the number of loads originating and
terminating in any given area.

      Our marketing strategy emphasizes service.  A key element of this strategy
is our strong commitment to satisfying the individualized requirements of our
customers.  In addition, we have developed an electronic data interchange
("EDI") system.  We use this system to provide customers with current
information on the status of shipments in transit.  Customers also place orders,
and we bill customers, electronically using this system.  We also use a
satellite tracking system to enhance monitoring of shipment locations.

      We maintain marketing offices in our Mondovi, Wisconsin headquarters, as
well as in other locations throughout the United States.  Marketing personnel
travel in their regions to solicit new customers and maintain contact with
customers.  Once we establish a customer relationship, the customer's primary
contact is one of our customer service managers.  Working from our terminal in
Mondovi, the customer service managers regularly contact customers to solicit
additional business on a load-by-load basis.  Each customer service manager is
assigned to particular customers and takes responsibility for monitoring overall
transportation, service requirements and shipments for each customer.  These
efforts to coordinate shipper needs with equipment availability have been
instrumental in maintaining an average empty mile rate of 6.6% in 1998.

      We set our own freight rates instead of using those published by tariff
publishing bureaus.  This allows us to offer rates that are more responsive to
market conditions and the level of service required by a particular customer. 
We have designed our rate structure to compensate us for the cost of protective
service revenue equipment as well as for hauling loads into areas generating
empty miles.

      A single customer, The Pillsbury Company, accounted for approximately 11%
of our revenue in 1998, 13% of our revenue in 1997 and 13% of our revenue in
1996.

OPERATIONS

      Our operations are designed to efficiently use our equipment while
emphasizing individualized service to customers.  Our EDI system provides
real-time and on-line shipment tracking information, increases equipment
utilization and assists management in long-range planning and trend analysis.

      We maintain our dispatch operations in our Mondovi, Wisconsin
headquarters.  We assign customer service managers to particular customers and
regions.  Customer service managers work closely with our fleet managers,
marketing personnel and drivers.  Customer service managers also coordinate with
our marketing personnel to match customer needs with our capacity and location
of revenue equipment.  Fleet managers, who are assigned a group of drivers
regardless of load destination, dispatch loads.  After dispatching a load, a
fleet 


                                          2
<PAGE>

manager takes responsibility for its proper and efficient delivery and tracks
the status of that load through daily contact with drivers.    During these
daily contacts, fleet managers and drivers discuss the driver's location, load
temperature and any problems.  We constantly update this information, along with
information concerning available loads, on our EDI computer system.  We use this
computer-generated information to meet delivery schedules, respond to customer
inquiries and match available equipment with loads. 

      Our primary traffic lanes are between the Midwest and the following
regions: West Coast, Pacific Northwest, Southwest, Southeast and the East Coast;
and from California to the Pacific Northwest and the Midwest.  The average
length of a trip (one-way) was 1,081 miles during 1998, 1,092 miles during 1997
and 1,095 miles during 1996.  Our loads generally move directly from origin to
destination, which eliminates the need for freight terminals.  We operate
maintenance facilities in Mondovi, Wisconsin; Ontario, California; Wilsonville,
Oregon; and Jonesboro, Georgia.

      We have agreements with various fuel distributors.  These agreements allow
our drivers to purchase fuel at a discount while in transit.  We also purchase
fuel in bulk in Mondovi and at our maintenance facilities.

DRIVERS

      As of December 31, 1998, we employed 1,026 drivers and had contracts with
independent contractors for the services of 466 tractors.  Independent
contractors provide both a tractor and a qualified driver for our use.  We
recruit drivers from throughout the United States.  The ratio of drivers to
tractors as of December 31, 1998, was approximately 1 to 1.  Our drivers are not
represented by a collective bargaining unit.  Our turnover of drivers was
approximately 62% in 1998.  Based on industry surveys, we believe our driver
turnover rate is in line with the industry.

      We select drivers, including independent contractors, using our specific
guidelines for safety records, driving experience and personal evaluations.  We
maintain stringent screening, training and testing procedures for our drivers to
reduce the potential for accidents and the corresponding costs of insurance and
claims.  We train new drivers at our Wisconsin terminal in all phases of our
policies and operations, as well as in safety techniques and fuel-efficient
operation of the equipment.  All new drivers must also pass DOT required tests
prior to assignment to a vehicle.  We maintain a toll-free number, satellite
tracking and a staff of fleet managers to communicate and support drivers while
on the road for extended periods.

      To retain qualified drivers and promote safe operations, we purchase
premium quality tractors and equip them with optional comfort and safety
features.  These features include air ride suspension on the chassis and cab,
air conditioning, high-quality interiors, power steering, engine brakes and
double sleeper cabs.  

      We pay company-employed drivers a fixed rate per mile.  The rate increases
based on length of service.  Drivers are also eligible for bonuses based upon
safe, efficient driving.  We believe that our compensation program provides an
important incentive to attract and retain qualified drivers.  Drivers that have
been with us for at least six months are also eligible to purchase shares of our
Common Stock under a stock purchase plan we sponsor.  We pay the brokerage
commissions on purchases and the plan's administrative costs.

      We pay independent contractors a fixed rate per mile.  Independent
contractors pay for their own fuel, insurance, maintenance and repairs. 
Independent contractors that have been under contract with us for at least six
months are also eligible to purchase shares of our Common Stock under a stock
purchase plan we sponsor.  We pay the brokerage commissions on purchases and the
plan's administrative costs.  

REVENUE EQUIPMENT

      The trucking industry requires significant capital investment in revenue
equipment.  We finance a portion of our revenue equipment purchases using
long-term debt.  We purchase tractors and trailers 


                                          3
<PAGE>

manufactured to our specifications.  Freightliner or Peterbilt manufacture most
of our tractors.  Most of our tractors are equipped with 435/500 or 370/435
horsepower Detroit Diesel or Cummins engines.  These engines enable the
equipment to maintain constant speed with optimum fuel economy under conditions
often encountered by our equipment, such as mountainous terrain and maximum
weight loads.  Utility, Great Dane or Wabash manufacture most of our single van
trailers.  Most of our trailers are equipped with Thermo-King cooling and
heating equipment.  Our single van refrigerated trailers are either 53 feet long
(1,605 trailers) or 48 feet long (489 trailers).  All of our trailers are 102
inches wide and have at least 106 inches of inside height.  We standardize
equipment to simplify driver training, control the cost of spare parts
inventory, enhance our preventive maintenance program and increase fuel economy.

      The following table shows the type and age of equipment we own as of
December 31, 1998:

</TABLE>

      We replace our tractors and trailers based on factors such as age, the
market for used equipment and improvements in technology and fuel efficiency. 
We have a comprehensive maintenance program for our company-owned tractors and
trailers to minimize equipment downtime and enhance resale or trade-in value. 
We regularly perform inspections, repairs and maintenance at our facilities in
Mondovi, Wisconsin; Ontario, California; Jonesboro, Georgia; and Wilsonville,
Oregon, and at independent contract maintenance facilities.

EMPLOYEES

      As of December 31, 1998, we employed 1,337 people.  This total consists of
1,026 drivers, 116 mechanics and maintenance personnel, along with 195 support
personnel.  Support personnel includes management and administration.  Our
employees are not represented by a collective bargaining unit.  We consider
relations with our employees to be good.

COMPETITION

      The trucking industry is highly competitive.  Our primary competitors are
other protective service truckload carriers and private carriage fleets.  For
freight not requiring protective service trailers, our competitors also include
dry freight truckload carriers and railroads.  To compete, we rely primarily on
our quality of service and our ability to provide protective service and other
specialized services.  We have substantially less financial resources, own less
equipment and carry less freight than several other truckload carriers offering
protective service.

REGULATION

      We are a motor common and contract carrier.   The DOT and the FHWA, along
with various state agencies, regulate our operations.  These regulatory
authorities have broad powers, generally governing 


                                          4
<PAGE>

activities such as authority to engage in motor carrier operations, rates and
charges, and certain mergers, consolidations and acquisitions.  The Motor
Carrier Act of 1980 (the "MCA") substantially increased competition among motor
carriers and limited the level of regulation in the industry.  The MCA allowed
applicants to obtain ICC operating authority more easily and allowed interstate
motor carriers to change their rates without ICC approval.  The law also removed
many route and commodity restrictions.  The Trucking Industry Regulatory Reform
Act of 1994 (the "TIRRA") has further increased industry competition and limited
industry regulation.  The TIRRA repealed tariff filing for individually
determined rates, simplified the granting of operating authority, and pre-empted
price, route and service regulation by the states.  Effective January 1, 1996,
the ICC Termination Act of 1995 abolished the ICC and transferred its regulatory
authority to the DOT and the FHWA.

      Motor carrier operations are subject to the DOT's safety requirements
governing interstate operations.  Matters such as weight and dimensions of
equipment are also regulated by federal and state authorities.

      We also have operating authority between the United States and the
Canadian Provinces of Alberta, British Columbia, Manitoba, Ontario, Quebec and
Saskatchewan.

ITEM 2.   PROPERTIES

      Our executive offices and principal terminal are located on approximately
seven acres in Mondovi, Wisconsin.  This facility consists of approximately
28,000 square feet of office space and approximately 21,000 square feet of
equipment repair and maintenance space.  Originally constructed in 1965, these
facilities were expanded in 1971, 1980, 1987 and 1993.  

      We maintain a maintenance facility in Ontario, California.  We purchased
this facility in 1997 for $1.5 million from R & R Properties, a
sole-proprietorship owned by Randolph L. Marten.  From 1985 through 1997, we
leased this facility from R & R Properties.  Total rental expense for this lease
was $126,000 per year during 1995 through 1997.  This facility includes
approximately 2,700 square feet of office space, 8,000 square feet of equipment
repair and maintenance space and a parking lot of 150,000 square feet.  

      We purchased a maintenance facility in Jonesboro, Georgia in 1993.  The
building at this facility is approximately 12,500 square feet and consists of
office space and a two and one-half bay service and repair space.  This facility
also has parking for up to forty tractors and trailers.

      We purchased a maintenance facility in Wilsonville, Oregon in 1995.  The
building at this facility is approximately 20,000 square feet and consists of
office space and an eight-bay service and repair space.  This facility also has
an eight-acre paved and fenced yard area.

ITEM 3.   LEGAL PROCEEDINGS

      We periodically are a party to routine litigation incidental to our
business.  Primarily, this litigation involves claims for personal injury and
property damage caused while transporting freight.  There are currently no
material pending legal, governmental, administrative or other proceedings to
which we are a party or of which any of our property is the subject which are
unreserved.

      We partially self-insure for losses relating to workers' compensation,
auto liability, general liability and cargo claims, along with employees' group
health benefits.  We self-insure for property damage claims.  We also maintain
an insurance policy that limits annual total losses to $7.5 million for auto
liability, workers' compensation and general liability claims.  We believe that
our current liability limit is reasonable.  However, we could suffer losses over
our policy limits.  Losses in excess of our policy limits could negatively
affect our financial condition.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

          Our credit facility described in Note 2 to the financial statements as
well as in the Management's Discussion and Analysis carries interest rate risk. 
Amounts borrowed under this agreement are subject to interest charges at a rate
equal to either the London Interbank Offered Rate plus applicable margins, or
the bank's Reference Rate.  The Reference Rate is generally the prime rate. 
Should the lender's Reference Rate change, our interest expense will increase or
decrease accordingly.  As of December 31, 1998, we had borrowed approximately
$4.8 million subject to interest rate risk.  On this amount, a 1% increase in
the interest rate would cost us $48,000 in additional gross interest cost on an
annual basis.

TO OUR SHAREHOLDERS AND EMPLOYEES                                              1

Our annual report is a welcome opportunity to communicate to shareholders, 
customers, prospects and employees the aspects of our business that make us 
successful, as well as to highlight our financial results. Our success, 
coupled with the discipline we use to manage our company, helps build 
Marten's reputation as a financially solid, respected transportation company.

The partnerships we form with drivers and independent contractors, non-driver 
employees, customers and suppliers are extremely important. This year, we'll 
describe how these individual partnerships contribute to Marten's continued 
growth and profitability.

1998 FINANCIAL HIGHLIGHTS

For the fiscal year ended December 31, 1998, we posted record revenue of 
$193.6 million, up 12 percent from $172.4 million in 1997. Net income for 
1998 increased 43 percent to $7.6 million, or $1.67 per diluted share, from 
$5.3 million, or $1.19 per diluted share, in 1997.

Operating income for 1998 was $16.3 million, compared with $12.8 million in 
1997. Marten's operating ratio, which compares operating costs to revenue, 
decreased to 91.6 percent in 1998 from 92.5 percent the year earlier.

Revenue gains stem from several factors. First, we increase the potential for 
higher revenue by enlarging our fleet. We went from 1,317 tractors and 1,835 
trailers at December 31, 1997, to 1,460 and 2,097, respectively, at December 
31, 1998. Second, we significantly expanded our dedicated service business, 
which I'll address later in this letter. Third, we increased our revenue from 
our top 10 customers by 9 percent in 1998. This reflects the solid 
relationships we maintain with our top customers.

A RELATIONSHIP BUSINESS

Operating a successful transportation business requires close partnerships 
with people inside and outside the organization. We recognize the need to 
build, maintain and manage partnerships, and we've designed programs and 
systems with our business partners to strengthen our service and financial 
performance. Key examples follow.

DRIVERS/INDEPENDENT CONTRACTORS: The industry-wide driver shortage continues 
to affect our business. To help manage our driver turnover, we provide 
referral bonuses to drivers who bring us qualified new recruits. We paid more 
than $140,000 in referral bonuses in 1998 -- an important investment in our 
future. Likewise, sharpening our focus on dedicated service programs also 
reduces driver turnover. Some employees like driving in dedicated lanes, 
which offers more predictable scheduling.

Independent contractors, who represent 31 percent of our total driver 
network, are extremely important to Marten. The Contractor Services Program 
launched in mid-1998 helps independent contractors (including former 
Marten-employed drivers) build their own businesses. The program includes 
accounting firm referrals, equipment advice, sources for insurance and other 
essential start-up elements. We've signed up 30 independent contractors for 
this program so far.

NON-DRIVER EMPLOYEES: Partnerships with non-driver employees at all four 
Marten locations -- from mechanics to fleet managers, sales and office 
personnel -- also are critical. Overall, we benefit from a very stable 
workforce. Two areas worth special note are Marten's empowering of terminal 
managers, who now have more control of day-to-day operations within their 
regions, and the introduction of a popular scholarship program for children 
of Marten employees.

In the area of terminal operations, we moved some of our daily operations 
management to regional staff. For example, instead of overseeing driver 
recruiting from our Mondovi headquarters, we solicit driver candidates from 
all four regional facilities. We've also asked regional managers to supervise 
many of the loading/unloading programs in their areas and maintain direct 
contact with many nearby customers, which helps improve service.

In 1998, we invested $10,000 in a new scholarship program for college-bound 
children of Marten employees. Last year, we received 17 applications and 
awarded scholarships to eight students. We expect an even larger number of 
applications this year.

CUSTOMERS: Many aspects of our business contribute to mutually beneficial 
customer relationships. Superior service and state-of-the-art equipment, for 
example, provide the capacity our customers require. We spend considerable 
time building an understanding of each other's needs. When customers 
understand the cost elements associated with running a transportation 
business,

<PAGE>

TO OUR SHAREHOLDERS AND EMPLOYEES                                              2

and we understand the implications of meeting customer requests, we form 
long-term, "win/win" partnerships. If we maintain open-ended communication, 
we can improve equipment utilization, reduce costs and increase margins.

We win business because we're responsive. We keep relationships because we 
have the equipment and flexibility to meet the individualized needs of every 
customer -- and because our people deliver the service level expected. We are 
known in the industry as a premier carrier for customers who require time- 
and temperature-sensitive service.

SUPPLIERS: We contract with equipment suppliers who provide the best tractors 
and trailers in the industry. The same is true of companies that supply 
technology resources to manage our business and vendors who help add speed to 
our system.

Many of our customers have very tight delivery windows and travel deadlines. 
Our information systems personnel work with our network, hardware and 
software vendors to design and maintain systems to our specifications. This 
allows us to successfully communicate with customers, drivers and Marten 
operations personnel.

We're in great shape to surpass $200 million in revenue in 1999, thanks in 
large part to the partnerships highlighted here. Our balance sheet is strong 
and our expense control disciplines continue to drive profitability. We have 
invested time and resources in response to the "Year 2000 problem" and don't 
anticipate that the costs to address this issue will have a material effect 
on our financial or service performance going forward. (See Management's 
Discussion and Analysis for details.)

I'd like to thank all who contribute to our continued success. Thanks 
especially to Robert Smith, promoted to chief operating officer last August, 
for his dedication to Marten and our business associates.

Sincerely,

/s/ Randolph L. Marten

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS Operating revenue for the year ended December 31, 1998, 
increased 12 percent over 1997, compared with increases of 18 percent in 1997 
and 6 percent in 1996. These increases were the result of transporting 
additional freight associated with increases to our fleet each of the last 
three years. Average freight rates and equipment utilization, measured by 
average miles traveled per tractor, increased in 1998 and 1997 due to 
stronger customer demand, as compared to 1996. Average freight rates and 
utilization declined in 1996. Our contracts with customers require fuel 
surcharges and rebates based on significant fluctuations in the price of 
diesel fuel. Operating revenue in 1998 was reduced by fuel rebates of $496,000
due to a decrease in the price of diesel fuel. Operating revenue was increased
by fuel surcharges of $1.2 million in 1997 and $1.4 million in 1996 due to an 
increase in the price of diesel fuel. We expect operating revenue in 1999 to 
exceed 1998 levels due primarily to planned revenue equipment additions.

Operating expenses in 1998 represented 91.6 percent of operating revenue, 
compared with 92.5 percent in 1997 and 95.8 percent in 1996. This ratio 
improved in 1998 and 1997 due primarily to an increase in the revenue generated
per tractor, reflecting more efficient utilization of our equipment. This ratio
was not as favorable in 1996 due to reduced equipment utilization and lower 
freight rates. The aggregate amount of operating expenses increased 11 percent
in 1998, 14 percent in 1997 and 11 percent in 1996.

The transportation of additional freight and expansion of our fleet caused 
most expense categories to increase during the last three years. Purchased 
transportation expense increased to 24.2 percent of revenue in 1998, compared 
with 20.8 percent in 1997 and 13.7 percent in 1996. These increases reflect 
planned growth in the number of independent contractor-owned vehicles. 
Independent contractors assume responsibility for their own

salaries, wages and benefits expense, fuel and fuel tax expense, and supplies 
and maintenance expense. As a result, our expenses in these categories have 
been reduced relative to revenue during the last three years. A significant 
decrease in the price of diesel fuel caused an additional reduction in fuel 
and fuel tax expense in 1998. A significant increase in the price of diesel 
fuel negatively impacted fuel and fuel tax expense in 1997 and 1996. An 
increase in our trailer fleet caused depreciation expense to increase during 
the last three years. Our insurance and claims expense continued to be 
positively impacted by our strong focus on driver safety and training, which 
has led to improved accident experience over the last three years. Insurance 
and claims expense represented 1.9 percent of revenue in 1998, compared with 
2.0 percent in 1997 and 4.7 percent in 1996. Our gain on disposition of 
revenue equipment has fluctuated over the last three years due to changes in 
the market value received for used revenue equipment. We anticipate our 1999 
operating expenses as a percent of revenue will remain at current levels.

Interest expense as a percent of revenue declined in 1998 to 2.0 percent of 
revenue, compared with 2.4 percent in both 1997 and 1996. This improvement 
was primarily caused by a decrease in our average long-term debt during 1998. 
We anticipate interest expense in 1999 as a percent of revenue will remain at 
1998 levels.

Our effective tax rate was 40 percent for the last three years. We expect the 
effective tax rate to be 40 percent or less in 1999.

In 1998, the Financial Accounting Standards Board issued Statement No. 133, 
"Accounting for Derivative Instruments and Hedging Activities," as discussed 
in Note 1 to the financial statements. This statement, effective in our first 
quarter of 2000, is expected to have minimal impact on our results of 
operations and financial position because we did not have significant 
derivative instruments as of December 31, 1998.

Inflation can be expected to affect most of our operating expenses. The 
impact of inflation, however, was minimal during the three years ended 
December 31, 1998.

CAPITAL RESOURCES AND LIQUIDITY Net cash provided by our operating activities 
in 1998 was $24,486,000. Our business requires significant capital 
expenditures to update and expand our fleet with new, more efficient tractors 
and trailers. We invested $29,262,000 in property and equipment and other 
assets in 1998, requiring net cash from financing activities of $3,840,000. 
We are committed to purchase approximately $26 million of new revenue 
equipment, net of trade-in allowances, in the first half of 1999. We have 
paid, and expect to pay, for these purchases using cash flows from operations 
and proceeds from long-term debt.

In 1998, we issued $25 million in Series A Senior Unsecured Notes and 
obtained a $40 million unsecured committed credit facility. The Senior Notes 
bear fixed interest at 6.78 percent and mature in 2008. The credit facility 
matures in 2001 and bears variable interest based upon, at our option, either 
the London Interbank Offered Rate plus applicable margins, or the bank's 
Reference Rate. The proceeds of these fundings were used to retire a 
substantial portion of existing long-term debt, causing current maturities of 
long-term debt to decrease. This reduction in current maturities resulted in 
a positive working capital position. Cash flows from operating activities 
have historically met our working capital needs despite a working capital 
deficit. The working capital deficit in prior years was caused by current 
maturities of long-term debt associated with additions to our fleet. Our 
operating profits, short turnover in accounts receivable and cash management 
practices allow us to effectively meet our working capital requirements. 
Short-term borrowings have not been and are not expected to be used to meet 
working capital needs. We believe our liquidity will adequately satisfy 
expected near-term operating requirements.

SEASONALITY The trucking industry experiences seasonal fluctuations in 
revenue and expenses. Our operations are consistent with this pattern. We 
experience revenue declines after the winter holiday season because our 
customers reduce shipments. Operating expenses temporarily increase in the 
winter due to reduced fuel efficiency and additional maintenance cost.

IMPACT OF YEAR 2000 Computer programs have historically been written to 
abbreviate dates by using two digits instead of four digits to identify a 
particular year. The so-called "Year 2000 problem" is the inability of 
computer software or hardware to recognize or properly process dates ending 
in "00" and dates after the Year 2000. Significant attention is being focused 
as the Year 2000 approaches on updating or replacing such software and 
hardware in order to avoid system failures, miscalculations or business 
interruptions that might otherwise result. Marten is taking the steps we 
believe are necessary to insure that this potential problem does not 
adversely affect our operating results in the future. We are continuing our 
as-yet incomplete assessment of the impact of the Year 2000 problem.

Marten has reviewed its internal information systems and believes that the 
costs and efforts to address the Year 2000 problem will not be material to 
our business, financial condition or results of operations, and may be 
resolved through replacements and upgrades to our software or hardware. The 
Year 2000 problem may, however, adversely impact Marten by affecting the 
business and operations of parties with which we transact business, although 
we are unable to precisely determine the likelihood or potential impact of 
any such event. There can be no assurance that Marten will be able to 
effectively address Year 2000 issues in a cost-efficient manner and without 
interruption to our business,

or that Year 2000 problems encountered by our suppliers, customers or other 
parties will not have a material impact on our business, financial condition 
and results of operations.

Marten's state of readiness for the Year 2000, our estimated costs associated 
with Year 2000 issues, the risks we face associated with Year 2000 issues and 
our Year 2000 contingency plans are summarized below.

STATE OF READINESS - Internally, we have implemented a three-phase process to 
assess Year 2000 compliance of our systems and remediate any material 
non-compliance. The phases are (1) to identify and test our material computer 
software and hardware in order to determine whether they are Year 2000 
compliant; (2) to correct or replace those software or hardware systems in 
which we determine there is a material problem with Year 2000 compliance; and 
(3) to internally test the corrected or upgraded systems in order to 
determine whether they are Year 2000 compliant. We have completed all three 
phases with respect to most of our material internally written and purchased 
information technology (IT) systems and non-IT systems and believe the 
systems are Year 2000 compliant. However, Marten also utilizes a sales and 
marketing system, an insurance claims management system and a maintenance 
tracking system, all of which are in the second phase. We expect these three 
systems will be through phase three and achieve Year 2000 compliance in 1999.

Externally, we have implemented a three-phase process to assess Year 2000 
compliance of the systems of our vendors and third-party servicers, and 
remediate any material non-compliance. The phases are (1) to identify the 
vendors and other third parties with whom we transact business and determine 
whether they are significant to our business ("core" parties); (2) to contact 
the vendors and other third parties with whom we do business by, among other 
methods, sending them letters and questionnaires designed to solicit 
information relating to the Year 2000 problem; and (3) to evaluate the 
responses received from the vendors and other third parties. The 
questionnaire we are using asks vendors and other third parties such 
questions as (i) whether they have a documented Year 2000 compliance plan, 
(ii) whether they are aware of any Year 2000 readiness issues that could 
affect Marten, (iii) whether, if such an issue exists, they have plans in 
place to ensure compliance, (iv) what their target date is for Year 2000 
compliance and (v) whether they have any contingency plans. We have 
substantially completed all three phases with respect to our vendors and 
third-party service providers. We plan to follow up during 1999 with our core 
vendors and third parties with whom we do business to update our information 
regarding the Year 2000 problem.

COSTS ASSOCIATED WITH YEAR 2000 ISSUES - We estimate that the future costs 
associated with implementing all phases of our Year 2000 assessment and 
resolving any Year 2000 problems will be between $100,000 and $200,000. This 
estimated range includes expenditures for both repairs and upgrades. We 
believe that these costs, assuming this estimate is accurate, would not have 
a material effect on our business, financial condition and results of 
operations. We estimate our costs to date associated with Year 2000 issues to 
be less than $25,000. We anticipate that cash flow from operations will be 
used to pay the costs to address Year 2000 issues. All Year 2000 costs are 
expensed as incurred.

RISKS ASSOCIATED WITH YEAR 2000 ISSUES - We are unaware of any material risk 
to Marten associated with Year 2000 issues at the present time. We believe 
that the reasonably likely worst case Year 2000 scenario is a decrease in the 
efficiency with which we procure and deliver loads, and a decrease in the 
efficiency with which we receive payment for services rendered. A decrease in 
efficiency, however, would not necessarily result in a decrease in business. 
We expect that load procurement, load delivery and billing all could be 
achieved through alternative methods within a relatively short period of 
time. Any disruption, however, could result in some lost revenue.

We face the additional risk of experiencing an increase in claims and 
litigation relating to the Year 2000 problem because, among other reasons, 
there is no uniform definition of Year 2000 "compliance" and because all 
vendor and third-party situations cannot be anticipated, particularly those 
involving third-party products. Such claims, if successful, could have a 
material adverse effect on future results. Moreover, the costs of defending 
Marten against such claims, even if ultimately resolved in our favor, could 
have a material adverse effect on future results.

CONTINGENCY PLANS - We have completed a specific contingency plan for the 
Year 2000 problem. This contingency plan identifies alternate vendors and 
service providers to decrease the impact on Marten if one or more of the core 
parties with whom we do business suffers a significant Year 2000 problem.

FORWARD-LOOKING INFORMATION This annual report contains certain 
forward-looking statements. Any statements not of historical fact may be 
considered forward-looking statements. Written words such as "may," "expect," 
"believe," "anticipate" or "estimate," or other variations of these or 
similar words, identify such statements. These statements by their nature 
involve substantial risks and uncertainties, and actual results may differ 
materially, depending on a variety of factors, such as the industry driver 
shortage, the market for revenue equipment, fuel prices and general weather 
and economic conditions.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS: Marten Transport, Ltd. is a long-haul truckload carrier 
providing protective service transportation of time- and 
temperature-sensitive materials and general commodities. We earned 
approximately 11 percent of our revenue from a single customer in 1998, 13 
percent in 1997 and 13 percent in 1996.

CASH EQUIVALENTS: We invest available funds in short-term cash equivalents. 
These investments are primarily mutual funds with U.S. government-backed 
securities having original maturities of three months or less. These 
investments are stated at cost, which approximates market value.

PREPAID EXPENSES AND OTHER: As of December 31, prepaid expenses and other 
consisted of the following:

</TABLE>

PROPERTY AND EQUIPMENT: Additions and improvements to property and equipment 
are capitalized at cost. Maintenance and repair expenditures are charged to 
operations. Gains and losses on disposals of revenue equipment are included 
in operations.

Depreciation is computed based on the cost of the asset, reduced by its 
estimated salvage value, using the straight-line method for financial 
reporting purposes. Accelerated methods are used for income tax reporting 
purposes. Following is a summary of estimated useful lives:

</TABLE>

TIRES IN SERVICE: The cost of original equipment and replacement tires placed 
in service is capitalized. Amortization is calculated based on cost, less 
estimated salvage value, using the straight-line method over 24 months. The 
current portion of capitalized tires in service is included in prepaid 
expenses in the balance sheets. The long-term portion of capitalized tires in 
service and the estimated salvage value are included in revenue equipment in 
the balance sheets. The cost of recapping tires is charged to operations.

INSURANCE AND CLAIMS: We self-insure, in part, for losses relating to 
workers' compensation, auto liability, general liability and cargo claims, 
along with employees' group health benefits. We self-insure for property 
damage claims. We maintain insurance coverage for per-incident and total 
losses in amounts we consider adequate based upon ongoing review and 
historical experience. We reserve currently for anticipated losses. The 
insurance and claims reserves are continuously evaluated and adjusted to 
reflect our experience. Under agreements with our insurance carriers and 
regulatory authorities, we have arranged for approximately $2.2 million in 
letters of credit to guarantee settlement of claims.

REVENUE RECOGNITION: We record revenue and related expenses on the date 
shipment of freight is completed.

ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: Statement of 
Financial Accounting Standards No. 133, "Accounting for Derivative 
Instruments and Hedging Activities" (Statement No. 133) was issued in June 
1998 and is effective in our first quarter of 2000. Statement No. 133 
requires companies to record the fair value of derivatives as either assets 
or liabilities on the balance sheet. The accounting for gains or losses from 
changes in the fair value of derivatives depends on the intended use of the 
derivatives and whether the criteria for hedge accounting have been 
satisfied. We have entered into commodity swap agreements to partially hedge 
Marten's exposure to diesel fuel price fluctuations. Statement No. 133 is 
expected to have minimal impact on Marten's results of operations and 
financial position because we did not hold significant derivative instruments 
as of December 31, 1998.

USE OF ESTIMATES: We must make estimates and assumptions to prepare the 
financial statements using generally accepted accounting principles. These 
estimates and assumptions affect the reported amounts of assets and 
liabilities and the disclosure of contingent assets and liabilities in the 
financial statements. The reported amounts of revenue and expenses in the 
financial statements are also affected. These estimates are primarily related 
to insurance and claims accruals and depreciation. Actual results could 
differ from these estimates.

The debt agreements contain restrictive covenants which, among other matters, 
require us to maintain certain financial ratios. We satisfied all debt 
covenants at December 31, 1998.

3. LEASES

We lease office equipment and facilities under operating leases with terms 
ranging from one to five years. Under most of these agreements, we pay 
maintenance and other expenses for the leased property.

Minimum future obligations under operating leases in effect at December 31, 
1998, are as follows:

4. RELATED PARTY TRANSACTIONS

The following related party transactions occurred during the three years 
ended December 31, 1998:

(a) We paid approximately $1.5 million in 1998 and $1.6 million in 1997 to 
purchase fuel and tires from a company in which one of our directors, elected 
in 1997, is the president and a shareholder.

(b) We purchased an office and terminal facility in 1997 for $1.5 million 
from an entity owned by our chairman of the board. We leased the facility 
under a non-cancelable operating lease with the same entity before it was 
purchased. Total rental expense charged to operations for this lease was 
$126,000 per year during 1997 and 1996.

(c) During the three years ended December 31, 1998, we have had checking, 
savings and investment accounts at banks which are controlled by one of our 
directors and officers.

We believe that these transactions with related parties are on reasonable 
terms which are comparable to terms available from unaffiliated third parties.

5. INCOME TAXES

We use the liability method of accounting for income taxes. Deferred taxes 
are calculated based on the estimated future tax effects of differences 
between the financial statement and tax bases of assets and liabilities given 
current tax laws.

The components of the provision for income taxes consisted of the following:

6. STOCK SPLIT

In 1997, our board of directors authorized a three-for-two stock split of our 
common stock, $.01 par value. Each shareholder of record received an 
additional one-half share for each share of common stock held as of the close 
of business on December 15, 1997. The additional shares were distributed on 
January 5, 1998. The stock split was effected in the form of a dividend, 
using authorized but unissued shares of our common stock. All per share 
amounts for 1997 and prior years have been retroactively adjusted to reflect 
the stock split.

7. EARNINGS PER COMMON SHARE

Basic and diluted earnings per common share were computed as follows:

</TABLE>

The following options were outstanding but were not included in the 
calculation of diluted earnings per share. The options' exercise prices were 
greater than the average market price of the common shares. Therefore, 
including the options in the denominator would be antidilutive, or decrease 
the number of weighted-average shares.

8. EMPLOYEE BENEFITS

STOCK INCENTIVE PLANS: Under our Stock Incentive Plan adopted in 1995, 
officers, directors and employees may be granted incentive and non-statutory 
stock options. Incentive stock option prices must be at least the fair market 
value of our common stock on the date of grant. Non-statutory stock option 
prices must be at least 85 percent of the fair market value of our common 
stock on the date the option is granted. Stock options expire within 10 years 
after the date of grant. The plan also allows for stock appreciation rights, 
restricted stock awards, performance units and stock bonuses, none of which 
have been awarded as of December 31, 1998. The maximum number of shares of 
common stock available for issuance under the plan is 750,000 shares.

In 1986, we adopted an Incentive Stock Option Plan and a Non-Statutory Stock 
Option Plan allowing for the grant of options. The option prices must be at 
least the fair market value of our common stock on the date of grant. In 
these plans, 375,000 shares of common stock are available for issuance to 
officers, directors and employees. Options under the Incentive Stock Option 
Plan expire within 10 years after the date of grant. Options under the 
Non-Statutory Stock Option Plan expire within 10 years and one month after 
the date of grant.

We account for these plans under Accounting Principles Board Opinion No. 25, 
"Accounting for Stock Issued to Employees," under which compensation cost is 
not recorded. If compensation cost had been recorded consistent with 
Statement of Financial Accounting Standards No. 123, "Accounting for 
Stock-Based Compensation" (Statement No. 123), our net income and earnings 
per common share would have been the following pro forma amounts:

Because the Statement No. 123 method of accounting has only been applied to 
options granted in 1995 or after, the pro forma comparison above may not be 
representative of the impact of compensation cost in future years.

As of December 31, stock option activity under our plans was as follows:

RETIREMENT SAVINGS PLAN: We sponsor a defined contribution retirement savings 
plan under Section 401(k) of the Internal Revenue Code. Employees are 
eligible for the plan after one year of service. Each participant can 
contribute up to 15 percent of compensation. We contribute 25 percent of each 
participant's contribution, up to a total of 4 percent contributed. Our 
contribution vests at the rate of 20 percent per year for the second through 
sixth years of service. In addition, we may make elective contributions as 
determined by the board of directors. Elective contributions were not made in 
1998, 1997 or 1996. Total expense recorded for the plan was $197,000 in 1998, 
$183,000 in 1997 and $192,000 in 1996.

STOCK PURCHASE PLANS: An Employee Stock Purchase Plan and an Independent 
Contractor Stock Purchase Plan are sponsored to encourage employee and 
independent contractor ownership of our common stock. Eligible participants 
specify the amount of regular payroll or contract payment deductions and 
voluntary cash contributions that are used to purchase shares of our common 
stock. The purchases are made at the market price on the open market. We pay 
the broker's commissions and administrative charges for purchases of common 
stock under the plans.

9. FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value of each class of financial instruments was estimated using the 
following methods and assumptions:

CASH AND CASH EQUIVALENTS: The carrying amount approximated fair value due to 
the short maturity of these instruments.

LONG-TERM DEBT: The fair value of our long-term debt approximated the 
carrying amount at December 31, 1998, and December 31, 1997. The fair value 
was estimated using discounted cash flow analysis. Our current borrowing 
rates for similar long-term debt were used in this analysis.

10. COMMITMENTS

We have commitments to purchase approximately $26 million of new revenue 
equipment, net of trade-in allowances, in the first half of 1999.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Marten Transport, Ltd.:

We have audited the accompanying balance sheets of Marten Transport, Ltd. (a 
Delaware corporation) as of December 31, 1998 and 1997, and the related 
statements of operations, changes in shareholders' investment and cash flows 
for each of the three years in the period ended December 31, 1998. These 
financial statements are the responsibility of the company's management. Our 
responsibility is to express an opinion on these financial statements based 
on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of Marten Transport, Ltd. as of 
December 31, 1998 and 1997, and the results of its operations and its cash 
flows for each of the three years in the period ended December 31, 1998, in 
conformity with generally accepted accounting principles.
