ITEM 1.   BUSINESS

GENERAL

     Great Lakes Aviation, Ltd. ("Great Lakes") is a regional airline, which 
during 1997 operated under three marketing identities (the "Regional 
Identities"):  United Express, Midway Connection and Great Lakes Airlines.  
The Company is one of several companies operating as United Express under 
code sharing agreements with United Air Lines, Inc. ("United").  While the 
Company does not compete against other United Express carriers on routes that 
it serves, it does compete with them to receive the right to serve additional 
markets under a United agreement.  On October 1, 1995 the Company began 
operating as Midway Connection under a code sharing agreement with Midway 
Airlines Corporation ("Midway"). The Midway Agreement was terminated on May 
16, 1997 and the Company ceased operating as Midway Connection.  On August 8, 
1995, the Company began operations in the Southwest United States and Mexico 
independently under its own code as Great Lakes Airlines.  This service was 
discontinued on May 16, 1997 although the Company still operates as Great 
Lakes Airlines on one route in the Midwest.  As of December 31, 1997, the 
Company's fleet consisted of 37 Beechcraft Model 1900 19-passenger aircraft 
and 10 Embraer Brasilia 30-passenger aircraft. References herein to the 
Company include Great Lakes and its wholly owned subsidiary, RDU, Inc.  RDU, 
Inc. currently has no activity and is not being utilized by the Company.

     The table below sets forth certain operating information for each of the 
Regional Identities for the year ended December 31, 1997.

</TABLE>

     The Company's recent performance has caused certain liquidity problems.  
See "Management's Discussion and Analysis of Financial Condition".

     On May 16, 1997 following inspections of the Company's operations by the 
Federal Aviation Administration ("FAA"), the Company and the FAA entered into 
an agreement whereby the Company voluntarily suspended flight operations 
pending a thorough review of the Company's maintenance and recordkeeping 
procedures.  On May 23, 1997, the Company resumed limited operations at five 
cities after entering into a Consent Order (the "Order") with the FAA.  The 
Order imposed a civil penalty of $1,000,000 of which $300,000 is being paid 
in installments through June 1, 1998 and $700,000 which will be forgiven if 
the Company complies with all of the terms and conditions of the Order.  The 
Order also required the Company to, among other things, inspect each of the 
Company's aircraft and demonstrate to the FAA's satisfaction that the Company 
has sufficient equipment, qualified personnel, manuals, systems, procedures 
and financial resources to safely conduct operations.  The Company believes 
it is in compliance with the Order as of the date of this filing.

                                       1
<PAGE>

     As a result of the voluntary suspension of service, the Company suffered 
lost revenues, incurred substantial maintenance expenses, continued operating 
expenses, and other related expenses.  In connection with the Order, each of 
the Company's aircraft underwent an FAA approved inspection prior to being 
returned to service.  At December 31, 1997, the Company had returned all but 
four of its Beech 1900 aircraft and two of its Brasilia aircraft to service.  
The cost of these inspections, as well as the expenses of terminating 
operations in the Southeast and Southwest (see Managements Discussion and 
Analysis--Overview), and the expected costs to eliminate aircraft surplus to 
the Company needs (see Aircraft--Summary of Additions and Deletions) have 
been included in the 1997 statement of operations as Shutdown and other 
Nonrecurring Expenses, as follows:

</TABLE>

     The Company has returned to its historical core route structure with the 
primary focus being that of the United Express Marketing Relationship.  
Within that relationship the Company is seeking to maximize its operating 
advantage at Chicago's O'Hare Airport where revenue passenger yields are 
relatively higher.  Service has also been reinstated at United's Denver hub 
and at Minneapolis/St. Paul for those routes that the Company believes are 
economically advantageous.

UNITED EXPRESS RELATIONSHIP

     The United Express operation serves 50 destinations in eleven states 
located in the Upper Midwest, with hubs located at Chicago O'Hare, Denver and 
Minneapolis/St. Paul, as of December 31, 1997.  The Company became a "United 
Express" carrier in 1992 under a code sharing agreement with United and is 
one of the principal United Express regional carriers.

     The code sharing agreement with United expired in December 1997.  The 
Company believes its relationship with United is satisfactory, as evidenced 
by United's recent selection of the Company as the United Express carrier for 
additional routes serving the Denver airport.  Since December 31, 1997, the 
Company has been operating as if the principal day-to-day operational 
provisions of the previous code sharing agreement are still effective.  The 
Company and United have entered into negotiations to renew the code sharing 
agreement.  The Company anticipates a favorable change in the method of 
allocating passenger fares which will increase the Company's share of the 
ticket price for passengers traveling a portion of their journey on United.  
As part of their negotiations, United has informed the Company that it 
intends to restructure its operating relationships with certain of its United 
Express carriers, pursuant to which the Company will provide service to 
Denver from fourteen additional cities effective April 23, 1998 and an 
additional four cities on June 1, 1998.  The effect of this will be that the 
Company will become the only United Express carrier providing service with 
nineteen seat aircraft at the Chicago and Denver hubs.  The Company also 
intends to reduce its service that it provides using 30 seat Brasilia 
aircraft.  While the Company expects a new code sharing agreement to be 
finalized on a mutually advantageous basis, no assurance can be given that 
this actually will be accomplished.  Certain material provisions of the prior 
code sharing agreement and related agreements (the "United Express 
Agreements") are described herein because any new code sharing agreement may 
contain similar terms.  Any failure to enter into a new code sharing 
agreement with United, any material adverse change in terms from the prior 
code sharing agreement, or any substantial decrease in the number of routes 
served by the Company under this agreement 

                                       2
<PAGE>

could have a material adverse effect on the Company's business.  As a result 
of the code sharing relationship with United, the Company's business is 
sensitive to events and risks affecting United.  If adverse events affect 
United's business, the Company's business may also be adversely affected.

     The United Express Agreements entitle the Company to use United's "UA" 
flight designator code to identify its code sharing flights and fares in 
computer reservation systems, United's "Apollo" reservation system (including 
United's automated check-in, ticketing and boarding pass, and advance seat 
reservation and baggage tracing systems), to use the United Express logo and 
aircraft exterior paint schemes and uniforms similar to those of United and 
to otherwise advertise and market its association with United. United Express 
passengers participate in United's "Mileage Plus" frequent flyer program and 
are eligible to receive a minimum of 500 United frequent flyer miles for each 
trip on a United Express flight. The United Express Agreements also provide 
for coordinated schedules and through fares.  A through fare is a cost-saving 
fare available to a prospective passenger who, in order to reach a particular 
destination, transfers between the major carrier and that carrier's code 
sharing partner. United establishes all through fares and the Company 
receives a portion of the fares on a formula basis, subject to periodic 
adjustment.

     United provides a number of additional services to the Company. These 
include publication of the fares, rules and related information that are part 
of the Company's contracts of carriage for passengers and freight; 
publication of the Company's code sharing flight schedules and related 
information using the United "UA" flight designator code and flight numbers 
assigned by United; provision of ticket handling services at United's 
ticketing locations; provision of airport signage at airports where both the 
Company and United operate; provision of United ticket stock and related 
documents; provision of expense vouchers, checks and cash disbursements to 
passengers on code sharing flights of Great Lakes inconvenienced by flight 
cancellations, diversions and delays; and cooperation in the development and 
execution of advertising, promotion and marketing efforts featuring United 
Express and the relationship between United and the Company.  The Company 
pays United a monthly fee based on the total number of revenue passengers 
boarded on all of Great Lakes' United Express flights.  This fee varies 
depending on whether the passenger travels through United hubs at Denver and 
Chicago, is carried to or from other airports served by United or if the 
passenger is carried between cities only served by Great Lakes.  The Company 
also receives an incentive amount for each passenger that connects with a 
United flight. 

     With the exception of certain pre-approved destinations connecting with 
Minneapolis/St. Paul or Detroit, the United Express Agreements require the 
Company to obtain United's prior consent to operate as a United Express 
carrier on all routes.  Additionally, the United Express Agreements restrict 
the Company's ability to decrease its service to Denver and Chicago O'Hare 
below certain minimum levels.  Great Lakes has the exclusive right to provide 
United Express service to and from Detroit and Minneapolis/St. Paul and on 
existing Great Lakes' routes to and from Chicago O'Hare and Denver.  The 
United Express Agreements, however, had prohibited the Company from entering 
into a code sharing agreement with any other airline at Chicago, Denver, Des 
Moines, Detroit, Minneapolis/St. Paul or Omaha.  The code sharing agreement, 
however, does not prohibit United from competing with Great Lakes, by 
initiating its own service. 

UNITED EXPRESS MARKETS   

CHICAGO

     The Company's service to the Chicago O'Hare market is anchored by its 
ownership of 54 slots and 20 slot exemptions and its lease of seven slots 
allocated by the FAA.  A slot is a 30 minute interval during the period from 
6:45 a.m. to 9:14 p.m. during which an airline may operate either a take-off 
or landing.   Flights in this market are used primarily to provide connecting 
opportunities with United flights. The Company's ability to increase its 
passenger volume at Chicago O'Hare is limited by its allocation of slots, and 
future increases in passenger volume are expected to come from increased load 
factors, the acquisition of additional slots and the concentrated use at 
O'Hare of currently operated larger aircraft.  See "Slot Allocation" and " 
Aircraft." During 1997, approximately 67 percent of the Company's passenger 
traffic was carried to or from Chicago. During 1997, approximately 50 percent 
of the Company's traffic at Chicago O'Hare connected with United, 5 percent 
connected with other airlines and 45 percent traveled exclusively on a Great 
Lakes flight ("on-line").  As of December 31, 1997, Great Lakes had 53 
weekday Chicago
                                       3
<PAGE>

O'Hare departures serving 28 destinations located in Iowa, Illinois, Indiana, 
Michigan, North Dakota, South Dakota and Wisconsin.

DENVER

     The Company's primary strategy at Denver is to implement service in 
markets where United and other major carriers have reduced service and to 
feed that traffic to this United hub.  The Company is currently in 
negotiations with United with respect to the sharing of the expenses of 
operating at the new Denver airport.  During 1997, approximately 25 percent 
of the Company's passenger traffic was carried to or from Denver. During 
1997, approximately 55 percent of the Company's traffic at Denver connected 
with United, 5 percent connected with other carriers and 40 percent were 
on-line. As of December 31, 1997, the Company had 24 weekday Denver 
departures serving 14 destinations located in Colorado, Kansas, Minnesota, 
Nebraska, North Dakota and South Dakota.

     In the first quarter of 1998, the Company was selected by United to 
replace another United Express carrier at ten Essential Air Service points in 
Colorado, Kansas, and Wyoming to be served from Denver, effective April 23, 
1998.  In addition, the Company plans to begin service to four additional 
cities in Nebraska, Colorado, Kansas, and Wyoming on that date.  It is 
anticipated that beginning June 1, 1998 the Company will add United Express 
service to four more cities in Colorado and New Mexico from Denver.  This 
additional service out of Denver is subject to FAA approval pursuant to the 
FAA Consent Order.

MINNEAPOLIS/ST. PAUL

     As of December 31, 1997, Great Lakes had 11 weekday departures serving 8 
destinations located in Colorado, Iowa, Michigan, Minnesota, North and South 
Dakota, Nebraska and Wisconsin. During 1997, services in the Minneapolis/St. 
Paul markets were substantially reduced and the remaining services are 
supported by the Essential Air Service Subsidy program.

ESSENTIAL AIR SERVICE PROGRAM

     The Airline Deregulation Act of 1978 ("The Deregulation Act") allowed 
airlines great freedom to introduce, increase and generally reduce or 
eliminate service to existing markets. Under the Essential Air Service 
Program, which is administered by the Department of Transportation (DOT), 
certain communities that received scheduled air service prior to the passage 
of the Deregulation Act are guaranteed specified levels of "essential air 
service." The DOT may authorize federal subsidies to compensate a carrier 
providing essential air service in otherwise unprofitable or minimally 
profitable markets. If these subsidies are eliminated the Company may 
discontinue service to some or all of the subsidized communities.


                                       4
<PAGE>

     At December 31, 1997, the Company served 21 essential air service 
communities on a subsidized basis.  The Company received $6.1 million, $3.5 
million and $2.6 million in essential air service subsidies for the years 
ended December 31, 1997, 1996 and 1995, respectively. An airline serving a 
community that qualifies for essential air services is required to give the 
DOT advance notice before it may terminate, suspend or reduce service. 
Depending on the circumstances, the DOT may require the continuation of 
existing service until a replacement carrier is found.  The Company has 
negotiated increases in rates and added additional cities and flight 
frequencies for which it receives subsidy revenue. Subsidy rates in effect at 
April 14, 1998 are expected to generate essential air service revenues of 
approximately $18.6 million on an annualized basis, as follows:

AIRCRAFT

GENERAL

     At December 31, 1997, the Company's fleet consisted of 37 Beechcraft 
1900 aircraft and 10 Embraer Brasilia aircraft, of which 25 Beechcraft 1900 
aircraft and eight Embraer Brasilia aircraft were operated in scheduled 
service.  The Company has leased or sub-leased eight 1900 Beechcraft to other 
operators.  As of December 31, 1997, the Company had four Beechcraft 1900 
aircraft and two Embraer Brasilia aircraft which had not yet been returned to 
service following the voluntary suspension of operation on May 16, 1997.  The 
Beechcraft 1900 aircraft are pressurized, radar equipped and offer a 300-mile 
per hour cruising speed for 19 passengers, plus cargo, with a range of 850 
miles. The Beechcraft 1900 aircraft is widely regarded by airlines as an 
efficient and reliable aircraft for regional service.  As of December 31, 
1997, the Company owned  seven of its Beechcraft 1900 aircraft and leased the 
remaining 30 under agreements with remaining terms ranging from three months 
to 18 years.

     The 30 passenger Embraer Brasilia aircraft are equipped with advanced 
avionics, have stand-up cabins, restrooms, are staffed with a flight 
attendant and offer a 360 mile per hour cruising speed with a range of 750 
miles.  As of December 31, 1997, the Company owned four of its Embraer 
Brasilia aircraft and leased the remaining six under agreements with 
remaining terms ranging from six to 15 years.

     (1) - 8 of these aircraft are subleased to other carriers
     (2) - These two aircraft have been returned to the lessor and the 
           estimated lease termination costs are included in Shutdown 
           and Other Nonrecurring Expenses 

     As part of the realignment of United's relationships with its United 
Express carriers, the Company has been authorized to replace service from 
Denver previously provided by another United Express carrier beginning April 
23, 1998. This service will be performed with Beech 1900 aircraft, and 
represents a significant expansion of the Company's current service.  In 
light of the Company's present and planned route structure, the Company has 
determined to reduce the size of its Brasilia fleet. In February 1998 the 
Company entered into an agreement with another carrier to sell its ten 
remaining Brasilia aircraft and related spare parts and specialized tooling, 
and disposed of one Brasilia aircraft pursuant to that agreement in March 
1998. Subsequent to the February 1998 agreement, management has determined to 
continue to utilize five Brasilia aircraft in its operations and accordingly, 
the Company is currently renegotiating the agreement with the other carrier 
to reduce the number of Brasilia aircraft to be sold. There can be no 
assurance that any modification to the February 1998 agreement will be made. 
The Company has included a net charge of $1.3 million in Shutdown and other 
Nonrecurring Expenses for 1997 to reflect the financial statement impact of 
the disposition of those aircraft expected to be sold in 1998. If management 
determines or if the Company is required to dispose of additional Brasilia 
aircraft, it is likely that a substantial additional charge to operations 
would be required.

     As of December 31, 1997, the average ages of the Company's owned and 
leased aircraft were 6.8 and 4.1 years, respectively. 

AIRCRAFT DEBT AND LEASES

     Raytheon Corporation together with its financing affiliate 
(collectively, "Raytheon") is the Company's primary aircraft supplier and 
largest creditor. The Company has financed all of its Beechcraft 1900 
aircraft and one of its Brasilia aircraft under lease and debt agreements 
with Raytheon. Raytheon has also provided a $5 million working capital line 
of credit to the Company collateralized by the Company's accounts receivable 
(together with the aircraft leases and debt agreement, the "Raytheon 
Agreements").  The Raytheon Agreements went into default during the first 
quarter of 1997 due to the Company's non-payment of scheduled amounts due. 

     On July 16, 1997 the Company reached an agreement with Raytheon pursuant 
to which Raytheon provided a short-term loan of $4 million.  This loan, and 
the $5 million working capital line of credit, which were due on July 29, 
1997, have been extended until June 30, 1998. The $4 million loan, as well as 
existing Raytheon indebtedness, has been collateralized with all previously 
unpledged Beech aircraft spare parts and equipment and accounts receivable.  
In addition, Raytheon was granted a ten year warrant, exercisable commencing 
July 16, 1998, to purchase one million shares of the Company's common stock 
at a price of $.75 per share. In connection with the July 16, 1997 agreement, 
all defaults under the Raytheon Agreements were waived.  

     Effective August 31, 1997, the Company restructured its Raytheon 
aircraft agreements, through a combination of sale-leaseback transactions and 
modifications to existing leases. The restructuring resulted in a total of 30 
Beech 1900 aircraft being financed under operating leases of various terms 
with monthly lease payments ranging from $18,000 to $40,000 per aircraft and 
seven Beech 1900C aircraft remaining as owned aircraft.  The restructuring 
also cured all of the defaults with Raytheon and resulted in a net gain of 
$1.5 million, which will be recognized over the life of the lease agreements.

                                       6
<PAGE>

     The Company has financed nine of its Brasilia aircraft through lease and 
debt agreements with other unrelated entities (collectively, the "Brasilia 
Agreements").  During 1997, all of the Brasilia Agreements went into default 
due to non-payment of scheduled amounts due.  All defaults under the Brasilia 
Agreements have been cured as of the date of this filing.  Two Brasilia 
aircraft which the Company had in its fleet at January 1, 1997, were returned 
to the lessor through the exercise of the lessor's rights as a result of the 
default. The lease on one of these aircraft has been assigned to another 
carrier and it is anticipated that the other lease will be assigned in the 
near future.  The estimated lease termination costs associated with these two 
returned aircraft are included in Shutdown, and Other Nonrecurring Expenses.

     On December 22, 1997 the Company became guarantor on an aircraft financing
agreement between Raytheon and a related party of the Company.  In January 1998
the aircraft were leased to the Company and subsequently sub-leased under short
term operating leases.

     The aircraft lease agreements contain provisions which the Company believes
are typical of leases for the type of aircraft involved. These terms include the
requirement that the Company pay all taxes, maintenance, insurance and other 
operating expenses; general and tax indemnities from the Company; 
condition-on-return provisions; and default provisions, including cross-default
provisions with other leases or agreements. 

MAINTENANCE

     The FAA mandates periodic inspection and maintenance of commercial 
aircraft. The Company performs most maintenance and inspection of its aircraft
and engines (except engine overhaul) using its own personnel. The Company 
supports its fleet by utilizing decentralized maintenance bases capable of 
performing these functions. During 1997, the Company reduced the number of these
bases from eighteen to five.  The remaining bases are located at:  Huron, South 
Dakota; Grand Island, Nebraska; Spencer, Iowa; Springfield, Illinois; Marquette,
Michigan. The Company attempts to perform its maintenance at locations where its
aircraft are stored overnight to reduce maintenance costs and promote a higher 
level of operating efficiency.  Parts and supplies inventories are also 
maintained at these locations to promote the mechanical dispatch reliability of 
the fleet. The Company also maintains an inventory of spare engines and 
propellers for its fleet to allow for minimal downtime during major overhauls. 
The Company performs certain major maintenance overhauls to its fleet, which it 
believes most other regional airlines have performed by outside contractors. 

SLOT ALLOCATION

     At Chicago O'Hare, scheduled flights between 6:45am and 9:14pm may be 
conducted only if an airline has obtained a slot. Of the 54 owned slots and 
20 slot exemptions allocated to the Company by the FAA as of December 31, 
1997, 37 may be used for aircraft with up to 75 seats and the remainder may 
be used for aircraft with up to 110 seats.

     Outstanding slots at FAA slot-controlled airports are currently freely 
exchanged between airlines and other persons, bought or sold (often with gates
or other on-ground assets), or leased. Slot values depend on several factors, 
including the airport, the time of day, the number and availability of slots, 
and whether they are commuter or air carrier slots. Interests in slots have also
been used by airlines as collateral to secure debt financing and other 
obligations. The DOT and FAA must be advised of all slot transfers and must 
determine that each such transfer will not be injurious to the Essential Air 
Service Program. The transfer of a slot obtained in an FAA-administered lottery
is limited for two years after its acquisition to either transfer for other 
lottery slots at the same airport or sales or leases to new entrants or 
incumbent slot holders with a small number of slots. 

     During January 1997 the Company was awarded its slot exemptions for the 
specific purpose of providing 20 operations per day between Chicago O'Hare 
Airport and Dubuque and Mason City, Iowa; Huron and Sioux Falls, South 
Dakota; and Fargo, North Dakota.  These slot exemptions may not be bought, 
sold or traded without DOT approval.

     The FAA's slot regulations require the use of each slot at least 80 
percent of the time, measured on a bi-monthly basis. Failure to do so without 
a waiver from the FAA (which is granted only in exceptional cases) subjects 
the slot to recall by the FAA. In addition, the slot regulations provide that 
slots do not represent a property right, but 

                                       7
<PAGE>

represent an operating privilege subject to FAA control and that slots may be 
withdrawn by the FAA at any time without compensation to meet the DOT's 
operational needs (such as providing slots for international or essential air 
transportation or providing slots for new entrant carriers). 

     Since the creation of the slot system in 1968, and subsequent to the 
adoption of the FAA's slot allocation, use and transfer regulations in 1985, 
there have been and are currently pending several proposals introduced in 
Congress and discussions within the DOT and the FAA regarding slots. In 
August 1993, the National Commission To Ensure A Strong Competitive Airline 
Industry recommended that the "FAA review the rule that limits operations at 
`high density' airports with the aim of either removing these artificial 
limits or raising them to the highest level consistent with safety 
requirements."  In August 1995, Congress passed legislation granting the FAA 
authority to create additional slots for essential air service, international 
and certain domestic jet operations.  The Company has received 48 slots 
(including 20 slot exemptions) to date pursuant to the August 1995 
legislation.

YIELD MANAGEMENT

     The Company closely monitors its inventory and pricing of available 
seats with a computerized yield management system.  This system enables the 
Company's revenue control analysts to examine the Company's past traffic and 
pricing trends and to estimate the optimal allocation of seats by fare class 
(the number of seats made available for sale at various fares).  The analysts 
then monitor each flight to adjust seat allocations and overbooking levels, 
with the objective of maximizing the total revenue for each flight. 

MARKETING

     The Company's services are marketed primarily by means of listings in 
computerized reservation systems and the OFFICIAL AIRLINE GUIDE, advertising 
and promotions, and through direct contact with travel agencies and corporate 
travel departments.  The Company's advertising and promotional programs 
emphasize the Company's close affiliation with United, including coordinated 
flight schedules and the right of the Company's passengers to participate in 
United's "Mileage Plus" frequent flyer program.

COMPETITION

     The Company competes primarily with regional and major air carriers and 
automobile transportation. The Company's competition from other air carriers 
varies from location to location and, in certain areas, comes from regional 
and major carriers who serve the same destinations as the Company but through 
different hub and spoke systems. The domestic airline industry has undergone 
major structural changes since the enactment of the Deregulation Act.  Since 
that time, there has been substantial consolidation and integration of both 
major and regional carriers, including the acquisition or association of most 
regional carriers by or with major carriers.  Deregulation has made possible 
the rapid entry of competitors into the Company's markets, and competitors 
are able to adjust fares rapidly to improve their competitive position.  

     Almost all markets are subject to a high degree of price competition 
both from established carriers and low fare jet carriers.  The Company 
believes, however, that its ability to compete in its market areas is 
strengthened by its code sharing relationships with United and United's 
substantial presence at Chicago O'Hare and Denver which enhance the 
importance to Great Lakes of the United "UA" flight designator code in the 
Upper Midwest. After May 16, 1997, the Company's scheduled operations at 
Minneapolis/St. Paul have been substantially reduced and the resources 
re-deployed to Chicago and Denver where United's dominant position will 
generate considerably greater connecting traffic to the Company's flights.  
The Company competes with other airlines by offering frequent flights, 
flexible schedules and low fares. In addition, the Company's competitive 
position benefits from the large number of participants in United's "Mileage 
Plus" frequent flyer programs who fly regularly to or from the markets served 
by the Company. The United Express Agreements do not prohibit United from 
competing with the Company.  The United Express Agreements require the 
Company to obtain United's written consent before commencing service as a 
United Express carrier on routes other than certain pre-approved routes.

     There can be no assurance that the Company will not experience increased 
competition from existing competitors or from new entrants on one or more of 
the Company's routes. 

                                       8
<PAGE>

FUEL

     The Company has not experienced difficulty with fuel availability and 
expects to be able to obtain fuel at prevailing prices in quantities 
sufficient to meet its future requirements. The Company contracts directly 
with refiners for the purchase of its fuel. Standard industry contracts 
generally do not provide protection against fuel price increases and do not 
ensure availability of supply.  Accordingly, a significant increase in the 
cost of fuel, if not accompanied by an equivalent increase in passenger 
revenues, could have a material impact on the Company's future operating 
results. 

EMPLOYEES

     On December 31, 1997, the Company had 794 full-time and 174 part-time 
employees as follows:

</TABLE>

     The Company's pilots are represented by the International Brotherhood of 
Teamsters.  Effective November 1, 1997, the Company and union reached an 
agreement which becomes amendable October 30, 2000.  During 1996 the flight 
attendants voted to be represented by the Teamsters Union, however, no 
collective bargaining agreement has been negotiated.

     The Company's mechanics are represented by the International Association 
of Machinists.  The current agreement became effective November 1, 1997 and 
becomes amendable on November 1, 2000.

     The Company believes that relations with its employees are satisfactory.

CHARTER AND FREIGHT SERVICE

     The Company uses available aircraft and from time to time leases four and 
six passenger aircraft from an affiliated company to provide charter services 
to private individuals, corporations and groups such as collegiate athletic 
teams. The Company also carries freight, mail and small packages on most of its
scheduled flights. Revenues from its charter flights and freight deliveries were
1.8 percent, 1.6 percent and 1.5 percent of the Company's total revenues for 
the years ended December 31, 1997, 1996 and 1995, respectively. 

REGULATION

     In accordance with the provisions of the Federal Aviation Act of 1958, 
as amended (the "1958 Act"), the Company is an air carrier subject to regulation
by the DOT, primarily with respect to economic matters, and is also subject to 
regulation by the FAA with respect to certain safety related matters. 

     The Deregulation Act eliminated many regulatory constraints so that 
airlines became free to set fares and, with limited exceptions, to establish 
domestic routes without the necessity of seeking government approval. The DOT 
is still authorized to establish consumer protection regulations; to prohibit 
certain pricing practices; to mandate conditions of carriage; and to make 
ongoing determinations of a carrier's fitness, willingness and ability to 
properly and lawfully provide air transportation. The DOT also has the power 
to bring proceedings for the enforcement of its regulations under the 1958 
Act, including the assessment of civil penalties and the revocation of 
operating authority, and to seek criminal sanctions. 

     The Company holds an air carrier-operating certificate issued by the FAA 
pursuant to Part 121 of its regulations. The Company, as a commuter air 
carrier, is licensed under Part 298 of the 

                                       9
<PAGE>

Economic Regulations of the DOT.  The Company is subject to the jurisdiction 
of the FAA with respect to its aircraft maintenance and operations, including 
equipment, ground facilities, dispatch, communications, training, weather 
observation, flight personnel and other matters affecting air safety.  To 
ensure compliance with its regulations, the FAA requires airlines to obtain 
an operating certificate and operations specifications for the particular 
aircraft and types of operations conducted by the carrier, all of which are 
subject to suspension or revocation for cause. 

     The Company is subject to the jurisdiction of the Federal Communications 
Commission regarding the use of its radio facilities. Local governments and 
authorities in certain markets have adopted regulations governing various 
aspects of aircraft operations, including noise abatement and curfews and use 
of airport facilities. The Company believes that it is in compliance with all 
such regulations. 

     The FAA heavily regulates the use of landing and take-off slots at 
Chicago O'Hare. The FAA has the authority to revoke a carrier's slots for 
failure to comply with FAA regulations. 

INSURANCE

     The Company carries the types and amounts of insurance required by the 
DOT and customary in the regional airline industry, including coverage for 
public liability, property damage, aircraft loss or damage, baggage and cargo 
liability and workers' compensation.  The United Express Agreements requires 
the Company to maintain certain specified levels of insurance coverage. The 
Company believes that the insurance is adequate as to amounts and risks 
covered. There can be no assurance, however, that the limits of the Company's 
insurance will be sufficient to cover any catastrophic loss. 

ITEM 2.   PROPERTIES

     The Company leases gate and ramp facilities at 51 airports where 
ticketing is handled by Company personnel.  Payments to airport authorities 
for ground facilities are based on a number of factors, including the amount 
of space used and flight volume.  The Company also leases aircraft 
maintenance and hangar space at 5 of the locations it serves.

     The Company leases approximately 15,000 square feet of space in Spencer, 
Iowa for its administrative, flight operations and maintenance offices, in 
addition to approximately 35,000 square feet of aircraft maintenance and 
hangar space located adjacent thereto. The Company leases an additional 
32,000 square feet of space in Spencer for administration and maintenance 
shops.  The Company believes that it has adequate facilities for the conduct 
of its current and planned operations. 

ITEM 3.   LEGAL PROCEEDINGS

     The Company is a defendant in a lawsuit arising from the collision of a 
small aircraft with one of the Company's Beechcraft 1900 aircraft in Quincy, 
Illinois on November 19, 1996.  The collision occurred at the intersection of 
two runways as the Company's aircraft was landing, and resulted in the death 
of all ten passengers and the two crewmembers.  The Company's insurance 
carrier is providing for the Company's defense in the lawsuit and the Company 
believes that all claims arising from the accident will be adequately covered 
by insurance.

     The Company is a party to several routine pending legal proceedings, 
none of which management believes are material to the Company. 

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS DURING FOURTH
          QUARTER OF FISCAL YEAR

     There were no matters submitted to a vote of the Company's shareholders 
during the three-month period ended December 31, 1997.

     The Company's Common Stock is currently listed on the NASDAQ National 
Market.  In September 1997, the NASD issued new listing requirements for the 
NASDAQ National Market System which became effective February 23, 1998.  The 
changes increase the standards for continued listing on the NASDAQ National 
Market.  Companies may qualify for continued listing under two different 
Continued Listing Standards.  Standard 1 requires, among other things, Net 
Tangible Assets greater than $4.0 million, Market Value of Public Float in 
excess of $5.0 million, and a minimum Bid price greater than $1 per share. 
Standard 2 requires, among other things, Market Value of Public Float in 
excess of $15.0 million, and a minimum Bid Price of $5 per share.  Currently, 
the Company is not in compliance with the minimum requirements under either 
of these standards.  Under Standard 1, the Company does not meet the Net 
Tangible Assets requirement.  It is the Company's position, that although not 
reflected in the Company's financial statements, if recorded, the value of 
the Company's airport slots at Chicago O'Hare would bring it into compliance 
with the Net Tangible Assets requirement. The Company will notify NASDAQ 
within the next 30 days of its noncompliance. The Company will inform NASDAQ 
of its plan of compliance and why the Company believes it is in compliance 
with the Net Tangible Assets requirement. No assurance can be given that the 
Company's position will be accepted by NASDAQ.

     Should the Common Stock be suspended from trading privileges on the 
NASDAQ National Market as a result of the Company's failure to comply with 
any of the above, or other applicable requirements, the Company, prior to 
re-inclusion, must comply with the applicable continued listing standards 
prior to continued listing.  However, should the Common Stock be terminated 
from trading privileges on the NASDAQ National Market, the Company, prior to 
re-inclusion, must comply with the applicable requirements for initial 
listing on the NASDAQ National Market, which are more stringent than the 
requirements for continued listing. There can be no assurance that the Common 
Stock will continue to be listed on the NASDAQ National Market.

     In the event that the Common Stock is delisted from the NASDAQ National 
Market and the Company fails other relevant criteria, trading, if any, in 
shares of Common Stock would be subject to the full range of the Penny Stock 
Rules. Under Exchange Act Rule 15g-8, broker-dealers must take certain steps 
prior to selling a penny stock, which steps include:  (i) obtaining financial 
and investment information from the investor; (ii) obtaining a written 
suitability questionnaire and purchase agreement signed by the investor; 
(iii) providing the investor a written identification of the shares being 
offered and in what quantity; and (iv) deliver to the investor a written 
statement setting forth the basis on which the broker or dealer approved the 
investor's account for the transaction.  If the Penny Stock Rules are not 
followed by a broker-dealer, the investor has no obligation to purchase the 
shares.  Accordingly, delisting from the NASDAQ National Market and the 
application of the comprehensive Penny Stock Rules would make it more 
difficult for broker-dealers to sell the Common Stock, purchasers of shares 
of Common Stock would have difficulty in selling such shares in secondary 
transactions and the per share price of such stock would likely be greatly 
reduced.

     As of March 31, 1998, the Company had approximately 1,800 holders of its 
Common Stock.  The closing price of its common stock on April 15, 1998, as 
reported by the NASDAQ National Market was $3.00 per share. 

     The transfer agent for the Company's Common Stock is Norwest Bank 
Minnesota, N.A., 161 North Concord Exchange, South St. Paul, Minnesota, 
55075-0738, telephone: (612) 450-4064.

     The Company has not paid any dividends on its Common Stock since its 
initial public offering in January 1994 and expects that for the foreseeable 
future it will follow a policy of retaining earnings in order to finance the 
continued development of its business.  Payment of dividends is within the 
discretion of the Company's Board of Directors and will depend upon the 
earnings, capital requirements and operating and financial condition of the 
Company, and any applicable restrictive debt and lease covenants, among other 
factors.

     revenue passengers and is calculated by dividing revenue passenger miles 
     by available seat miles.

(4)  "Break-even passenger load factor" represents the percentage of 
     available seat miles which must be flown by revenue passengers at the 
     average yield (net of commissions and fees) for airline operations to 
     break even.

(5)  "Average yield per revenue passenger mile" represents the average 
     passenger revenue received for each mile a revenue passenger is carried.

(6)  "Operating cost per available seat mile" represents operating expenses 
     divided by available seat miles.

(7)  "Average passenger fare" represents passenger revenue divided by the 
     number of revenue passengers carried.

(8)  "Average passenger trip length" represents revenue passenger miles 
     divided by the number of revenue passengers carried.

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

OVERVIEW

     The discussion and analysis throughout this filing contains certain 
forward-looking terminology such as "believes," "anticipates," "will," and 
"intends," or comparable terminology.  Such statements are subject to certain 
risks and uncertainties that could cause actual results to differ materially 
from those projected.  Potential purchasers of the Company's securities are 
cautioned not to place undue reliance on such forward-looking statements 
which are qualified in their entirety by the cautions and risks described 
herein and in other reports filed by the Company with the Securities and 
Exchange Commission.

     The Company began providing air charter service in 1979, and has 
provided scheduled passenger service in the Upper Midwest since 1981.  In 
April 1992, the Company began operating as a United Express carrier under a 
cooperative marketing agreement with United.   As of December 31, 1997, the 
Company served 51 destinations in eleven states with 192 scheduled departures 
each weekday.

     As discussed in Item 1. BUSINESS, General, the Company suspended flight 
operations on May 16, 1997 and pursuant to the Order resumed limited 
operations on May 23, 1997.  Additionally, the Company discontinued service 
as Midway Connection in the Southeast United States and as Great Lakes 
Airlines in the Southwest United States and Mexico on May 16, 1997.  
Operating revenues from these two markets decreased to $13.5 million in 1997 
from $23.3 million in 1996. The Company anticipates that this reduction in 
service will have a positive impact on profitability since the Company's 
focus will be on its core business. Both Midway Connection and Great Lakes 
Airlines in the Southwest United States and Mexico were operated at a loss.  
Throughout the remainder of 1997, the Company returned all but four of its 
Beech 1900 aircraft and two of its Brasilia aircraft to service.

     As part of the realignment of United's relationships with its United 
Express carriers, the Company has been authorized to replace service from 
Denver previously provided by another United Express carrier beginning April 
23, 1998. This service will be performed with Beech 1900 aircraft, and 
represents a significant expansion of the Company's current service.  In 
light of the Company's present and planned route structure, the Company has 
determined to reduce the size of its Brasilia fleet. In February 1998 the 
Company entered into an agreement with another carrier to sell its ten 
remaining Brasilia aircraft and related spare parts and specialized tooling, 
and disposed of one Brasilia aircraft pursuant to that agreement in March 
1998. Subsequent to the February 1998 agreement, management has determined to 
utilize five Brasilia aircraft in its operations and accordingly the Company 
is currently renegotiating the agreement with the other carrier to reduce the 
number of Brasilia aircraft to be sold. There can be no assurance that any 
modification to the February 1998 agreement will be made. The Company has 
included a net charge of $1.3 million in Shutdown and other Nonrecurring 
Expenses for 1997 to reflect the financial statement impact of the 
disposition of those aircraft expected to be sold in 1998. If management 
determines or if the Company is required to dispose of additional Brasilia 
aircraft, it is likely that a substantial additional charge to operations 
would be required.

     The Company has suffered significant recurring losses and negative cash 
flows, which raise substantial doubt about its ability to continue as a going 
concern.  The Company's viability as a going concern depends upon its return 
to sustained profitability.

     OPERATING REVENUES:  Operating revenues decreased 23.6% to $83.8 million 
in 1997 from $109.7 million during 1996.  The decrease in operating revenues 
resulted from the decrease in revenue passenger miles flown by 32.3% to 202.7 
million in 1997 from 299.6 million during 1996 offset by increase of 2.4 cents 
in yield per revenue passenger mile to 37.1 cents in 1997 from 34.7 cents in 
1996. This coincided with a 35.4% decrease in capacity to 438.3 million ASMs 
in 1997 from 678.3 million ASMs during 1996. The increase in passenger yield 
is due primarily to price increases in key markets, moving service from lower 
yield markets to higher yield markets, and due to an increased emphasis on 
managing the quantity of seats made available for sale at discounted rates.  
In addition, public service revenue increased 74.3% to $6.1 million in 1997 
from $3.5 million in 1996. 

     OPERATING EXPENSES:  Total operating expenses decreased 17.5% to $97.4 
million, or 22.2 cents per ASM, in 1997 from $118.1 million, or 17.4 cents 
per ASM in 1996.  The increase in cost per ASM reflects the costs associated 
with the voluntary shutdown and the corresponding decrease in ASMs.

     Salaries, wages, and benefits expense increased to 5.0 cents per ASM 
during 1997, from 4.1 cents per ASM during 1996, due to normal pay increases 
and a smaller ASM base across which to spread fixed labor costs.

     Aircraft fuel expense per ASM increased to 3.0 cents in 1997 from 2.9 
cents in 1996 due to increased fuel prices from suppliers and the 
reinstatement of the 4.3 cents per gallon federal excise tax on jet fuel in 
August 1996, affecting all of 1997 and only five months in 1996.

     Aircraft maintenance and repairs expense decreased to 1.6 cents per ASM 
during 1997, from 2.0 cents per ASM in 1996 due to a decrease in the number 
of engine overhauls performed in 1997.

     Aircraft expense increased to 4.5 cents per ASM during 1997, from 3.4 
cents per ASM in 1996 due to reduced utilization because of the previously 
discussed voluntary suspension of flight operations. 

     Other rentals and landing fee expenses increased to 1.2 cents per ASM 
during 1997, from 1.0 cents per ASM in 1996, as a result of fixed facility 
costs spread over a lower ASM base.

     Other operating expenses increased to 4.6 cents per ASM in 1997 from 3.8 
cents in 1996, reflecting fixed expenses, including general and administrative,
marketing, and communications, spread across a lower ASM base in 1997.  In 
addition, 1997 includes higher passenger booking fees on an ASM basis due to 
increases in rates and higher United program fees since a higher percentage of 
the Company's flying was under the United Code in 1997 versus 1996.

     Shutdown and other nonrecurring expenses of 2.1 cents per ASM represents 
the estimated costs associated with the voluntary shutdown and the one-time 
charge for the write-down of the Brasilia aircraft.  This expense includes 
$7.9 million related to salaries and wages, aircraft maintenance materials 
and repairs, aircraft ownership costs, facilities rental, and other expenses 
directly related to the shutdown.  The remaining $1.3 million for the 
Brasilia aircraft reduction represents a reduction of the carrying value of 
the aircraft to their estimated net realizable value, accrued estimated 
future unrecoverable lease payments, accrued estimated lease termination 
costs, and a reduction of the carrying value of the spare part inventories to 
net realizable value offset by the recognition of related deferred purchase 
incentives on these aircraft.

     (BENEFIT) FOR INCOME TAXES:  No income tax benefit was recorded for 1997 
considering that the Company is in a loss carry forward position and that the 
realization of any benefits of such are substantially in doubt. 

COMPARISON OF 1996 TO 1995

     OPERATING REVENUES:   Operating revenues increased 30.3% to $109.6 
million in 1996 from $84.2 million during 1995.  The increase in operating 
revenues resulted from the increase in revenue passenger miles flown by 20.5% 
to 299.6 million in 1996 from 248.6 million during 1995 and an increase of 
9.8% in yield per revenue passenger mile, which increased from 31.6 cents in 
1995 to 34.7 cents in 1996.  This coincided with a 19.8% increase in capacity 
to 678.3 million ASMs in 1996 from 566.3 million ASMs during 1995.  The 
addition of Midway Connection and Arizona service for the entire year 
accounted for 54.6% and 26.8%, respectively, of the increase in operating 
revenues.  The increase in passenger yield is due primarily to the expiration 
of the 10% transportation tax without a corresponding 

                                       17
<PAGE>

reduction in ticket prices and increases in certain fares.  Midway 
Connection's full year operation increased the overall average as a result of 
its higher yield produced from its passengers with shorter trips.

     OPERATING EXPENSES:  Total operating expenses increased to $118.1 
million, or 17.4 cents per ASM, in 1996 from 85.0 million, or 15.0 cents per 
ASM in 1995. In part, the increase in cost per ASM is due to decreased 
utilization of the Embraer 120 aircraft because of two airworthiness 
directives requiring frequent propeller inspections and lack of replacement 
propeller blades during the first quarter of 1996.  The increase of total 
operating expenses reflect the costs associated with expansion of the 
Company's aircraft fleet and increased level of operations, except as 
detailed below.

     Salaries, wages, and benefits expense increased to 4.1 cents per ASM 
during 1996, from 3.8 cents per ASM during 1995, due to additional flight 
attendant wages and additional pilot guarantees and training costs incurred 
related to expansion of operations utilizing Brasilia aircraft, FAA 
Regulations Part 121 training, and customer service salaries to facilitate 
the Company's expansion into new markets.  In addition, mechanic wages 
increased because of the previously discussed Brasilia propeller inspections 
and replacement and increases in the number of mechanics to build staff to 
required levels.

     Aircraft fuel expense per ASM increased to 2.9 cents in 1996 from 2.5 
cents in 1995 due to increased fuel prices from suppliers and the 
reinstatement of the 4.3 cents per gallon federal excise tax on jet fuel in 
August 1996.

     Aircraft maintenance, and repairs expense increased to 2.0 cents per ASM 
during 1996, from 1.6 cents per ASM, in 1995, due to higher engine overhaul 
expense and increased repairs and contract labor for the initial on-going 
periodic maintenance checks on the Brasilia.

     Depreciation and amortization decreased to 0.8 cents per ASM in 1996 
from 1.1 cents per ASM in 1995, while aircraft rental expense increased to 
1.7 cents per ASM during 1996, from 0.9 cents per ASM in 1995, due to the 
increasing number of aircraft leased, along with the conversion of five 
capital leases to operating leases in June 1996.

     Other rentals and landing fee expenses increased to 1.0 cents per ASM 
during 1996, from 0.9 cents per ASM in 1995, as a result of higher facility 
and landing fee costs at the new Denver International Airport, along with 
increased administrative facility costs necessary for the Company's expansion 
into new markets.

     Other operating expenses increased to 3.8 cents per ASM in 1996 from 3.1 
cents in 1995, reflecting higher passenger booking fees due to increases in 
rates and increased bookings for the Midway Connection and higher credit card 
expenses for the Midway Connection and Great Lakes Airlines operations.  
These expenses were also increased due to flight cancellations resulting from 
severe weather conditions in upper Midwest and to unanticipated turnover in 
flight personnel due to major carrier hiring.  During the fourth quarter of 
1996, the Company accelerated its program to replace its Beechcraft 1900C 
aircraft with 1900D aircraft.  As a consequence, the Company believes it has 
excess Beechcraft 1900C inventory and has made an adjustment for $1.5 million 
dollars to reduce the inventory to estimated net realizable value.  These 
increases were partially offset by lower United program fees due to increased 
flying under the Company's own code and insurance proceeds from the November 
accident.

     INTEREST EXPENSE:  Interest expense decreased to 0.9 cents per ASM, in 
1996 from 1.3 cents per ASM, during 1995, due to decrease in the prime 
interest rate to which a substantial portion of debt is tied.

     (BENEFIT) FOR INCOME TAXES:  The Company's effective rate was 10.2 
percent in 1996 and 35.9 percent in 1995.  In recognition of the Company's 
financial results of recent periods the Company has ceased recognizing future 
tax benefits until it is more likely than not that such benefits will be 
realized.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has suffered significant recurring losses and negative cash 
flows, which raise substantial doubt about its ability to continue as a going 
concern. The Company has no further availability on its $5 million line of 
credit with Raytheon. The Company is heavily dependent on Raytheon and United 
for its liquidity requirements, however neither Raytheon nor United is under 
any current obligation to provide further financing to the Company. The 
Company's viability as a going concern depends upon its return to sustained 
profitability.


                                       18 


<PAGE>

     The Company's working capital decreased to ($5.6) million at December 
31, 1997 from $0.6 million at December 31, 1996.  Cash decreased $6.7 million 
to $0.0 million at December 31, 1997 from $6.7 million at December 31, 1996.  
The major uses of working capital in 1997 were a net loss of $18.3 million 
offset by non cash charges for depreciation of $4.2 million, deferral of 
lease payments of $5.9 million and the decrease in accounts receivable, 
inventories, and prepaid expenses totaling $4.1 million.  These changes are a 
result of the Company's reduced level of operations in 1997.

     Raytheon is the Company's primary aircraft supplier and largest 
creditor. The Company has financed all of its Beechcraft 1900 aircraft and 
one of its Brasilia aircraft under related lease and debt agreements with 
Raytheon, and Raytheon has also provided a $5 million working capital line of 
credit, collateralized by accounts receivable. The Raytheon Agreements went 
into default in 1997 due to the Company's non-payment of scheduled amounts 
due. 

     On July 16, 1997 the Company reached an agreement with Raytheon pursuant 
to which Raytheon provided a short-term loan of $4 million.  This loan, and 
the $5 million working capital line of credit which were due on July 29, 
1997, have been extended until June 30, 1997. The $4 million loan, as well as 
existing Raytheon indebtedness, has been collateralized with all previously 
unpledged Beech aircraft spare parts and equipment and accounts receivable.  
In addition, Raytheon was granted a warrant for a period of ten years, 
exercisable commencing July 16, 1998, to purchase one million shares of the 
Company's common stock at a price of $.75 per share.  In connection with the 
July 16, 1997 agreement, all defaults under the Raytheon Agreements were 
waived.

     Effective August 31, 1997, the Company restructured its Raytheon 
aircraft agreements.  The restructuring resulted in a total of 30 Beech 1900 
aircraft under operating leases of various terms with monthly lease payments 
ranging from $18,000 to $40,000 per aircraft and seven (7) Beech 1900C 
airliners remaining as owned aircraft.  The restructuring also cured all of 
the defaults with Raytheon. The restructuring resulted in a net deferred gain 
of $1.5 million, which will be recognized over the life of the lease 
agreements.

     In addition, the Company has financed nine of its Brasilia aircraft 
through lease and debt agreements with other unrelated entities 
(collectively, the "Brasilia Agreements").  During 1997, all of the Brasilia 
Agreements went into default due to non-payment of scheduled amounts due.  
All defaults under the Brasilia Agreements have been cured as of the date of 
this filing.  Two Brasilia aircraft, which the Company had in its fleet as of 
January 1, 1997 were returned to the lessor through the exercise of the 
lessor's rights as a result of the default.  The lease on one of these 
aircraft has been assigned to another carrier and it is anticipated that the 
other lease will be assigned in the near future, thereby terminating the 
lease without a significant expense to the Company.  The lease costs 
associated with these two returned aircraft are included in Excess Aircraft, 
Shutdown, and Other Non-recurring Expenses.

     Although the Company has decreased its accounts payable balance from 
December 31, 1996, it continues to have past due trade accounts.  Notes 
totaling approximately $1.8 million have been issued in 1997 to certain of 
the vendors, which, in general, require payment over a one-year period.  The 
balance of these notes was $.7 million as of December 31, 1997.  The Company 
believes that it has reached an appropriate accommodation with its key 
suppliers and that it will be able to obtain necessary goods and services on 
acceptable terms as long as timely payment is made for current purchases.

     Capital expenditures related to aircraft and equipment totaled $1.1 
million in 1997, $2.6 million during 1996, and $18.2 million in 1995.  
Payment of debt exceeded borrowings by $14.2 million in 1996.  Long-term 
borrowings exceeded principal repayments by $10.2 in 1995.  

     Long-term debt, net of current maturities of $2.2 million, totaled $28.5 
million at December 31, 1997 compared to $66.0 million net of current 
maturities of $5.1 million, at December 31, 1996, and $87.5 million, net of 
current maturities of $4.8 million at December 31, 1995.  As a result of the 
restructuring of the Company's Raytheon aircraft agreements, long term debt 
decreased $40.6 million.  As of December 31, 1997, the term notes bear 
interest at rates ranging from 7.5 to 9.1 percent and are payable monthly or 
quarterly through July, 2007.  All long-term debt as of December 31, 1997, 
relates to the acquisition of aircraft and is collateralized by 11 related 
aircraft.  There are no financial covenants related to such long-term debt.

YEAR 2000 IMPACT ON COMPUTERS

     Many currently installed computer systems and software products are 
coded to accept only two-digit entries in the date field.  These date code 
fields will need to accept four digit entries to distinguish 21st century 
dates from 20th century dates.  As a result, in approximately two years, 
computer systems and software used by many companies may need to be upgraded 
to comply with such "Year 2000" requirements.

     The Company has started to review its computer systems and application 
programs for year 2000 compliance. The Company can not give any assurances 
that The Company's systems nor the systems of other parties upon which the 
Company must rely, will be year 2000 compliant on a timely basis.  Examples 
of  systems operated by others that the Company may use and or rely upon are: 
 FAA Air Traffic Control, Computer Reservation Systems for travel agent sales 
and United Airlines' reservation, passenger check in and ticketing systems.  
The Company's business, financial condition and or results of operations 
could be materially adversely affected by the failure of its systems and 
applications or those operated by others.

SEASONALITY

     Since commencing operations, the Company has traditionally experienced 
lower passenger load factors during the months of January through April, 
November and December.  This seasonality can be attributed primarily to 
relatively difficult winter weather operating conditions in the Company's 
principal area of operations and fewer vacations and other discretionary 
trips and reduced business travel during these months.  These seasonal 
factors have generally resulted in reduced revenues, profitability and cash 
flow for the Company during these months. 

FREQUENT FLYER PROGRAM

     On the Company's United Express passengers may earn miles in United's 
"Mileage Plus" and frequent flyer program, and passengers may use mileage 
accumulated in this program to obtain discounted or free tickets for trips 
that might include a flight segment on one of the Company's flights.  No 
revenues are earned or collected on free tickets awarded to passengers under 
the program. Awards earned under the frequent flyers program have an 
expiration date three years from the date earned.  The program also contains 
certain restrictions, including blackout dates and capacity controlled 
bookings, which substantially limit the use of awards on certain flights and 
during the busiest periods.  The Company continually monitors the number of 
free travel award reservations on its flight segments to ensure that they are 
within the capacity restrictions defined in the "Mileage Plus" program.  The 
Company's yield management program and related seat restrictions minimize the 
number of revenue passengers that may be displaced on any individual flight 
segment.  To date, the Company has not experienced any material use of 
"Mileage Plus" and awards to obtain travel on flights, and the incremental 
cost to the Company attributable to the exercise of frequent flyer awards 
(consisting primarily of a minimal amount of additional gate and passenger 
service expenses) has not been material.  Awards used on the Company's 
flights during the year ended December 31, 1997 represented approximately 
2.6% percent of the Company's total passengers.  The Company expects that 
this percentage will remain approximately the same for the foreseeable 
future.  Based on this low percentage, on the availability on many of the 
Company's flights of otherwise vacant seats, and on the program's 
restrictions, the Company believes that the displacement, if any, of revenue 
passengers by users of "Mileage Plus" and awards will not become material.  
The Company continually monitors the number of awards redeemed and will 
accrue the incremental costs associated with the "Mileage Plus" and program 
if they become material.

EFFECTS OF INFLATION

     Inflation has not had a material effect on the Company's operations in 
the past five years.

CAUTIONARY STATEMENTS FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS OF THE 
PRIVATE SECURITIES LITIGATION REFORM ACT OF 1996

CAUTIONARY FACTORS

     The Company wishes to caution shareholders and prospective investors 
that the following important factors, among other identified in this Annual 
Report on Form 10-K, could affect the Company's actual operating results, and 
that such results could differ materially from those expressed in any 
forward-looking statements made by the Company.  The statements under this 
caption are intended to serve as cautionary statements within the meaning of 
the Private Securities Litigation Reform Act of 1996.  The following 
information is not intended to limit in any way the characterization of other 
statements or information under other captions as cautionary statements for 
such purpose.  The order in which such factors appear below should not be 
construed to indicate their relative importance or priority.

DEPENDENCE ON RELATIONSHIP WITH UNITED

     The Company generated approximately 84% of its revenues for the year 
ended December 31, 1997 under the United Express Agreements described under 
"Business - United Express Relationship".  The United Express Agreements 
required the Company to comply with specific operating performance standards 
and, with certain limited exceptions, restrict the ability of the Company to 
merge with another company or dispose of its assets or aircraft without first 
offering United a right of first refusal to acquire the Company or such 
assets or aircraft.  The United Express Agreements also prohibited the 
Company from entering into similar arrangements with other carriers in 
Chicago, Denver, Minneapolis-St. Paul, Detroit, Des Moines or Omaha without 
United's prior approval.  The United Express Agreements required the Company 
to obtain United's prior consent to operate as a United Express carrier in 
any market, except for certain pre-approved markets connecting with 
Minneapolis-St. Paul or Detroit.  The United Express Agreements terminated on 
December 31, 1997.  The Company believes its relationship with United is 
satisfactory, as evidenced by United's recent selection of the Company as the 
United Express carrier for additional routes serving the Denver airport. 
Since December 1997, the Company has been operating as if the day-to-day 
operational provisions of the previous code sharing agreement are still 
effective.  A failure to renew the United Express Agreements, any termination 
or materially adverse modification of the agreements, or any substantial 
decrease in the number of routes served by the Company under the agreements 
would have a materially adverse effect on the Company's business.  As a 
result of the United Express Agreements, the Company's business is sensitive 
to events and risks affecting United.  If adverse events affect United's 
business, the Company's business will also be adversely affected.

EFFECT OF GENERAL ECONOMIC CONDITIONS

     The airline industry is significantly affected by general economic 
conditions.  During recent recessions, most airlines reduced fares in an 
effort to increase traffic.  Economic and competitive conditions in the 
airline industry have contributed to a number of bankruptcies and 
liquidations among airlines.  A worsening of current economic conditions, or 
an extended period of recession nationally or regionally, would have a 
materially adverse effect on the Company's operations.

FUEL COSTS

     Fuel is a major component of operating expense for all airlines.  The 
Company's cost of fuel varies directly with market conditions, and the 
Company has no guaranteed long-term sources of supply.  The Company intends 
generally to follow industry trends by raising fares in response to 
significant fuel price increases.  However, the Company's ability to pass on 
increased fuel costs through fare increases may be limited by economic and 
competitive conditions. Accordingly, a reduction in the availability or an 
increase in the price of fuel could have a materially adverse effect on the 
Company's cash flow from operations and profitability.

SEASONALITY

     Historically, the Company has experienced lower passenger load factors 
during the months of January through April.  This seasonality can be attributed
primarily to relatively difficult winter weather operating conditions in the 
Company's principal area of operations, resulting in fewer vacations and other
discretionary trips and reduced business travel during these months.  These 
season factors have generally resulted in reduced revenues, increased operating
losses and reduced cash flow for the Company during these months.

CONTROL BY PRINCIPAL STOCKHOLDER

     Mr. Voss beneficially owns approximately 62% of the outstanding shares 
of the Company's common stock.  On October 22, 1996, Mr. Voss transferred 
approximately one-half of the shares of the Company's common stock owned by 
him, to now his ex-spouse, Ms. Gayle R. Voss, pursuant to the Marital 
Dissolution Stipulation and Property Settlement.  Ms. Voss has granted Mr. 
Voss an Irrevocable Proxy to vote such securities until June 28, 2010.  In 
addition, the terms of the United Express Agreements require that Mr. Voss 
control at least 51% of the Company's outstanding voting stock.  Accordingly, 
Mr. Voss will continue to be in a position to control the management and 
affairs of the Company.

NO ASSURANCE AS TO LIQUIDITY ON THE NATIONAL MARKET SYSTEM

     The Company's common stock is currently listed on The NASDAQ National 
Market System.  As discussed in Part II, Item 5, the Company may not be 
compliance with the new continued listing requirements. There can be no 
assurance that the Company's common stock will be actively traded on such 
market or that it will continue to be listed on such market.

               REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Great Lakes Aviation, Ltd.:

We have audited the accompanying consolidated balance sheets of Great Lakes 
Aviation, Ltd. (an Iowa corporation) and Subsidiary as of December 31, 1996 
and 1995, and the related consolidated statements of operations, stockholders' 
equity and cash flows for each of the years then ended. 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 Great Lakes Aviation, Ltd. 
and Subsidiary as of December 31, 1996 and 1995, and the results of its 
operations and its cash flows for each of the years then ended, in conformity 
with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the 
Company will continue as a going concern. As discussed in Note 3 to the 
financial statements, the Company has suffered significant losses in 1996 and 
1995 and negative operating cash flow in 1996, has been unable to meet its 
significant current and long-term financial obligations, and has defaulted on 
certain financial and operating agreements. These matters raise substantial 
doubt about its ability to continue as a going concern. Management's plans in 
regard to these matters are also described in Note 3. The financial statements 
do not include any adjustments relating to the recoverability and 
classification of asset carrying amounts or the amount and classification of 
liabilities that might result should the Company be unable to continue as a 
going concern.

Our audits were made for the purpose of forming an opinion on the basic 
financial statements taken as a whole. The supplemental schedule to the 
consolidated financial statements is presented for the purposes of complying 
with the Securities and Exchange Commission's rules and is not part of the 
basic financial statements. This schedule has been subjected to the auditing 
procedures applied in the audits of the basic financial statements, and, in 
our opinion, fairly states in all material respects the financial data 
required to be set forth therein in relation to the basic financial statements 
taken as a whole.

                           INDEPENDENT AUDITOR'S REPORT

The Board of Directors
Great Lakes Aviation, Ltd.:

We have audited the accompanying consolidated balance sheet of Great Lakes 
Aviation, Ltd. (an Iowa Corporation) and subsidiary as of December 31, 1997, 
and the related consolidated statements of operations, stockholders' equity, 
and cash flows for the year then ended. In connection with our audit of the 
consolidated financial statements we have also audited the financial 
statement schedule for the year ended December 31, 1997. These financial 
statements and the financial statement schedule are the responsibility of the 
Company's management. Our responsibility is to express an opinion on these 
financial statements and the financial statement schedule based on our audit.

We conducted our audit 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 audit provides a 
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of Great 
Lakes Aviation, Ltd. and subsidiary as of December 31, 1997, and the results 
of their operations and their cash flows for the year then ended, in 
conformity with generally accepted accounting principles. Also in our 
opinion, the related financial statement schedule for the year ended December 
31, 1997, when considered in relation to the basic financial statements taken 
as a whole, presents fairly, in all material respects, the information set 
forth therein.

The accompanying consolidated financial statements have been prepared 
assuming that the Company will continue as a going concern. As discussed in 
note 3 to the consolidated financial statements, the Company has suffered 
significant losses in each of the last three years, and a result has 
insufficient liquidity to pay its obligations as they come due, and has 
defaulted on certain financial and operating agreements. These matters raise 
substantial doubt about the Company's ability to continue as a going concern. 
Management's plans in regard to these matters are also described in note 3. 
The consolidated financial statements do not include any adjustments that 
might result from the outcome of this uncertainty.

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                          DECEMBER 31, 1997 AND 1996

(1)  CORPORATE ORGANIZATION AND BUSINESS

     CORPORATE ORGANIZATION

     The consolidated financial statements include the accounts of Great 
          Lakes Aviation, Ltd. (Great Lakes) and its wholly owned subsidiary, 
          RDU Inc. (RDU), referred to collectively herein as the Company. All 
          significant inter-company accounts and transactions have been 
          eliminated in consolidation.

     BUSINESS

     As of December 31, 1997, the Company provides scheduled passenger and 
          air freight service via two marketing identities (United Express 
          and Great Lakes Airlines), the first of which operates under a 
          code-sharing agreement.

     The Company operates as United Express under a cooperative marketing 
          agreement (United Express Agreement) with United Airlines, Inc. 
          (United) and provides service to 50 destinations in the Upper 
          Midwest as of December 31, 1997. The United Express Agreement 
          expired December 31, 1997, which had been extended on a monthly 
          basis from April 25, 1997. The Company and United are currently 
          operating under the terms of the previous United Express Agreement 
          (see note 3). Approximately 50 percent, 45 percent, and 40 percent 
          of the United Express passengers connected with United for the 
          years ended December 31, 1997, 1996, and 1995, respectively.  
          Outside the scope of the United Express Agreement, the Company 
          serves limited destinations in the Upper Midwest as Great Lakes 
          Airlines.

     From October 1, 1995 to May 16, 1997, the Company operated as a "Midway 
          Connection" carrier under a cooperative marketing agreement (Midway 
          Connection agreement) with Midway Airlines, Inc. (Midway) and 
          served Raleigh/Durham from 14 destinations in eight states located 
          along the East Coast as of December 31, 1996. Approximately 50 
          percent of Midway Connection passengers connected with Midway. The 
          Midway Connection operation was terminated on May 16, 1997 after 
          the Company temporarily suspended flight operations (see note 2).

     In August 1995, the company foreclosed under a security Agreement and 
          acquired certain assets of Arizona Airways. Inc. From August 1995 
          to May 16, 1997, the company served nine destination in Arizona, 
          New Mexico, and Mexico (collectively, the Southwest) as Great Lakes 
          Airlines. The Company terminated their operations in the Southwest 
          after the company temporarily suspended flight operation (see note 
          2).
 
     Revenues during 1997, 1996, and 1995 were derived 84 percent, 79 percent 
          and 97 percent from United Express operations, 8 percent, 13 
          percent and 1 percent from Midway Connection and 8 percent, 8 
          percent and 2 percent from Great Lakes Airlines operations.

     During October 1995, the Company sold certain landing and takeoff slots 
          at Chicago O'Hare airport to United, generating a gain of $3,850,000 
          (see note 9).

                                        29                           (Continued)

(2)  SHUTDOWN AND OTHER NONRECURRING EXPENSES

     Under terms of a consent order (the Order) with the Federal Aviation 
          Administration (FAA), the Company temporarily suspended its flight 
          operations on May 16, 1997 and resumed flight operations on a 
          limited basis on May 23, 1997 (the Shutdown). Under terms of the 
          Order, the Company was assessed a civil penalty of $1,000,000, of 
          which $700,000 of the civil penalty will not be paid if the Company 
          complies with all terms of the Order for a one year period ending 
          May 23, 1998. The Order, among other things, required the Company 
          inspect each aircraft and demonstrate to the FAA's satisfaction 
          that the Company has sufficient equipment, qualified personnel, 
          manuals, systems and financial resources to safely conduct 
          operations. As of December 31, 1997, the Company believes that it 
          has complied with the terms of the Order and Management anticipates 
          doing so through the end of the Order. The Company's results for 1997
          reflect a charge of $300,000 for the portion of the penalty paid to 
          date.

     Subsequent to the Shutdown, the Company incurred continuing operating 
          expenses, significant maintenance expenses and other expenses 
          related to the shutdown. Those expenses have been included in the 
          statement of operations and are classified as shutdown and other 
          nonrecurring expenses.

     When flight operations were resumed, on reduced basis on May 23, 1997, 
          the Company terminated its flight operations as Midway Connection 
          and as Great Lakes Airlines in the Southeastern and Southwestern 
          United States, respectively. The costs related to the termination 
          of operations in those areas are included in shutdown and other 
          nonrecurring expenses.

     In connection with the reduced flight operations discussed above, the 
          Company has identified seven Embraer Brasilia 30 passenger aircraft 
          (Brasilia) (including two aircraft which were returned to the lessor 
          in June, 1997 as discussed in note 5), as being excess, which are not 
          needed by the Company to conduct its core United Express operation 
          servicing Chicago O'Hare, and to a lessor extent Denver and 
          Minneapolis.  Additionally, the Company has four Beechcraft 
          1900C 19 passenger aircraft which are idle at December 31, 1997. 
          Subsequent to May 16, 1997, the Company has disposed of thirteen 
          Beechcraft 1900C aircraft considered to be excess though sales or 
          leasing or subleasing arrangements to other parties.

     The Company's intent is to dispose of seven Brasilia aircraft (including 
          two aircraft which were returned to the lessor in June, 1997 as 
          discussed in note 5). The Company has, consistent with its intent 
          to dispose of seven Brasilia aircraft, reduced the carrying value 
          of owned aircraft to their estimated net realizable value, accrued 
          future lease payments estimated to be unrecoverable, accrued 
          estimated lease termination costs, and reduced the carrying value 
          of the related Brasilia spare part inventories to their net 
          realizable value. In February 1998, the Company entered into an 
          agreement to sell all of their remaining Brasilia aircraft and 
          their Brasilia spare part inventories and began negotiating with 
          the lessors and creditors for release of the Brasilia aircraft. In 
          April 1998, the Company determined that they have a continued need 
          for five of their Brasilia aircraft, and began negotiating with the 
          other party for a modification of the agreement. As of April 15, 
          1998, the existing agreement to sell all of the Company's Brasilia 
          aircraft has not been modified, and there can no assurance that the 
          other party will agree to the modification. As discussed above, 
          consistent with the Company's intent, the Company has accrued 
          diposal and lease termination costs for seven Brasilia aircraft. 
          Under terms of the existing agreements, the Company has disposed of 
          three aircraft to date. Management expects that four additional 
          Brasilia aircraft will be disposed of during the remainder 1998. 
          Management currently expects that it will continue to utilize the 
          five remaining Brasilia aircraft in its operations. However, if 
          management latter determines to dispose of these aircraft, it is 
          likely that a substantial additional charge to operations would be 
          required.

                                      30                           (Continued)

(3)  LIQUIDITY AND GOING-CONCERN MATTERS

     The Company has suffered significant losses in each of the last three 
          years, and as a result, has had insufficient liquidity to pay its 
          obligations as they come due, and has defaulted on certain 
          financial and operating agreements. These matters raise substantial 
          doubt about its ability to continue as a going concern. The 
          Company's ability to continue as a going concern depends upon 
          successfully negotiating deferrals or a restructuring of its 
          financial obligations, negotiating extended terms under its major 
          operating agreements, and ultimately, returning to sustained 
          profitability. The accompanying consolidated financial statements 
          have been prepared on a going concern basis which assumes 
          continuity of operations and realization of assets and liquidation 
          of liabilities in the ordinary course of business. The consolidated 
          financial statements do not include any adjustments that might 
          result if the Company were forced to discontinue its operations.

     Raytheon Aircraft Corp. and its financing affiliates (collectively, 
          "Raytheon") is the Company's primary aircraft supplier and largest 
          creditor. The Company has financed all 37 of its Beechcraft 1900 
          aircraft and one of its Brasilia aircraft under related lease and 
          debt agreements with Raytheon, and Raytheon has also extended the 
          Company a $5 million line of credit and a $4 million short term 
          note both of which are secured by accounts receivable and Beech 
          aircraft spare parts and equipment (collectively, the "Raytheon 
          Agreements"). The Raytheon Agreements went into default in 1997 due 
          to the Company's nonpayment of scheduled amounts due. The Raytheon 
          Agreements also contain cross-default provisions which may be 
          triggered if the Company's obligations to other creditors are 
          accelerated as a result of nonpayment of those obligations. The 
          default provisions of the Raytheon Agreements give Raytheon the 
          right to accelerate certain amounts due under the Raytheon 
          Agreements or repossess the aircraft or other assets securing the 
          Raytheon Agreements.

(3)  LIQUIDITY AND GOING-CONCERN MATTERS, CONTINUED

     The Company reached agreements with Raytheon in the third quarter of 
          1997 resulting in the restructuring of all of its Raytheon aircraft 
          agreements, which cured all defaults with Raytheon and allowed the 
          Company to defer certain lease payments (see note 5). The $4 million 
          short term note, discussed above, which originally expired in July 
          1997, has been extended to June 30, 1998. While the Company intends 
          to seek a further extension of the loans there can be no assurance 
          that Raytheon will agree to further extensions.

     In addition, the Company has financed 11 of its Brasilia aircraft 
          through five lease and debt agreements with other unrelated 
          entities (collectively, the "Brasilia Agreements"). During 1997, 
          all of the Brasilia Agreements went into default due to nonpayment 
          of scheduled amounts due. One of these Brasilia Agreements has been 
          subsequently modified to allow deferral of payment of the scheduled 
          amounts. Except as discussed in the following paragraph, the 
          Company has cured all of the other Brasilia Agreement defaults 
          during the year, either by entering into a short term note agreement 
          or by making the payments current. Remedies available under the 
          default provisions of the Brasilia Agreements have not been 
          exercised, but include possible repossession and resale of the 
          related aircraft, with the Company being responsible to pay any 
          shortfall between such sale proceeds and the balance of the 
          underlying obligations.

     The Company has returned two Brasilia aircraft to a lessor in June 1997. 
          In addition the Company has entered into a short term note 
          agreement in August 1997 with the lessor which covered unpaid 
          rentals due at that time. In 1998, the Company's lease agreement 
          was terminated, the Company is currently in negotiation with the 
          lessor in respect to unpaid rentals, lease termination costs and 
          the outstanding balance of a short term note agreement. The Company 
          has accrued estimated lease termination costs in the 1997 financial 
          statements. Actual results of these ongoing negotiations of the 
          lease termination could differ materially from these estimates.

     As discussed in note 2, the Company has signed an agreement to deliver 
          all remaining of its Brasilia aircraft (including the two discussed 
          above) to another party through sales and lease agreements (as 
          discussed above, the Company is currently negotiating a 
          modification of the agreement to sell all of their Brasilia 
          aircraft, and intends on disposing seven Brasilia aircraft). The 
          Company is currently in negotiations with the other related 
          Brasilia aircraft lessors and creditors to terminate the existing 
          leases and debt arrangements that would allow them to deliver the 
          aircraft. In the first quarter of 1998, the Company has entered 
          into a lease termination agreement with one of their Brasilia 
          lessors that leases the Company two Brasilia aircraft. There can be 
          no assurance that the Company will be able to reach other 
          acceptable agreements with the remaining Brasilia lessors and 
          creditors that will allow them to deliver the aircraft under terms 
          of the agreement. As of December 31, 1997, the Company has accrued 
          estimated costs related to lease terminations and losses expected 
          from the sale of owned aircraft and related spare parts. Actual 
          results from the disposition of the Brasilia aircraft could differ 
          materially from these estimates.

     During 1996 and through the third quarter of 1997, the Company has 
          extended and increased the past due amounts owed to its trade 
          vendors. The Company entered into several short term note 
          agreements totaling approximately $1.8 million with vendors 
          allowing them to pay the remaining balances, generally over a one 
          year period. As of December 31, 1997 the Company had remaining 
          short term note balances related to these agreements of 
          approximately $.7 million. The Company has also entered into 
          various other agreements with trade vendors allowing them to 
          continue operations. The Company has significantly reduced the 
          total trade payable balances during the third and fourth quarters 
          of 1997, but continues to have a significant amount of trade 
          payables past due. There can be no assurance that the Company's 
          trade vendors will continue to supply the Company with goods and 
          services on terms acceptable to the Company or that they will 
          further agree to any credit accommodations on past due amounts owed.

     On April 25, 1997, the United Express Agreement expired. The United 
          Express Agreement was extended on a monthly basis until December 
          31, 1998. In 1998, the Company and United have operated under the 
          terms of the previous United Express Agreement. Currently, the 
          Company is in default of a covenant of the previous United Express 
          Agreement as a result of its nonpayment of invoices when due. The 
          Company earns the majority of its revenues under the United Express 
          Agreement and, in exchange for certain per passenger fees, receives 
          certain benefits from its relationship with United including the 
          listing of its flights under United's computer reservation system 
          code. Management is negotiating with United to renew the United 
          Express Agreement. While management believes that initial 
          discussions have been favorable, there can be no assurance that 
          such negotiations will be successful or that the United Express 
          Agreement will be renewed or extended on terms acceptable to the 
          Company.

     Since its inception in October 1995 until May 16, 1997, significant 
          operating losses were incurred from the Company's operations under 
          the Midway Connection Agreement. This is partially attributable to 
          the fact that Midway reduced the number of aircraft in its 
          operation early in 1996 rather than expanding operations as it had 
          originally planned. This reduced the number of connecting 
          opportunities for the Company's flights and, in turn, potential 
          traffic which could use the Company's services. During the first 
          quarter of 1997, the Company eliminated certain unprofitable routes 
          and the number of aircraft committed to Midway services was reduced 
          from twelve to ten.

     As discussed in note 2, the Company terminated all of their operations 
          as a Midway Connection serving the Southeastern United States, 
          following the temporary suspension of flight operations on May 16, 
          1997. The remaining ten aircraft that had been committed to serving 
          the Southeastern United States, after being recertified by the FAA, 
          were returned to serving in the Company's core operation in the 
          Midwest, are currently idle and are considered to be in excess to 
          the Company's current operating needs or have been subleased to 
          other parties. The Company and Midway are currently negotiating on 
          the final settlement of their agreement that was to expire on 
          October 1, 1997. The settlement is not expected to have a material 
          adverse effect on the financial statements or operations of the 
          Company.

     The Company has made several revisions to its flight schedule in 1997, 
          including as previously discussed, the termination of operations as 
          Midway Connection in the Southeastern United States and as Great 
          Lakes Airlines in the Southwestern United States. Additionally in 
          the first quarter of 1998, the Company has announced its plan to 
          operate certain routes as United Express serving the Western United 
          States out of Denver. It is anticipated the Company will start 
          flying the additional routes in the second quarter of 1998. The 
          Company has continued to analyze opportunities in 1997 and the 
          first quarter of 1998 to improve its revenues, to increase revenue 
          passenger yields, and reduce operating expenses. The Company is 
          also analyzing opportunities to rationalize its capacity levels, 
          optimize its aircraft fleet and mix (including, as previously 
          discussed eliminating seven Brasilia aircraft from its operations), 
          and improve the deployment of its capacity. As part of the Consent 
          Order, the Company must satisfy the FAA that they have aircraft, 
          personnel, and other resources prior to commencing operations of 
          new routes. The Company is currently negotiating to obtain 
          additional Beechcraft 1900D 19 passenger aircraft, principally through
          lease agreements. Finally, the Company has recently negotiated 
          improved terms and subsidy rates on certain of its routes 
          subsidized by the U.S. Department of Transportation under the 
          Essential Air Service program.

(3)  LIQUIDITY AND GOING-CONCERN MATTERS, CONTINUED

     There can be no assurance the operational improvement initiatives the 
          Company has taken in 1997 and in the first quarter of 1998 will 
          result in improved operating performance or sustained 
          profitability. Additionally, there can be no assurance that the 
          agreements the Company has reached with their trade vendors and 
          creditors will continue on terms that are acceptable to the 
          Company. If the Company is unsuccessful in its efforts, it may 
          continue to be unable meet its current and future obligations, 
          making it necessary to undertake such other actions as may be 
          appropriate to preserve asset values, potentially including seeking 
          protection from its creditors under applicable bankruptcy laws.

(4)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ACCOUNTS RECEIVABLE

     Substantially all accounts receivable balances are due from various 
          airlines, with approximately 55 percent of the December 31, 1997, 
          balance and 42 percent of the December 31, 1996, balance due from 
          United. All receivables are pledged as collateral securing a 
          $5,000,000 line of credit and a $4,000,000 short term note.

     INVENTORIES

     Inventories consist of flight equipment spare parts and fuel and are 
          stated at the lower of average cost or market. An allowance for 
          depreciation is provided at rates which depreciate the cost of 
          flight equipment spare parts, less estimated residual value, over 
          the estimated useful lives of the related aircraft. The accumulated 
          allowances were $3,513,000 and $3,082,000, respectively, at 
          December 31, 1997 and 1996. At December 31, 1997, inventories 
          include the estimated realizable value of $2,008,000 Brasilia 
          related spare parts, of which the Company intends to dispose. 
          Expendable parts are charged to maintenance expense as used. 
          Inventories consisting of Beech aircraft spare parts and equipment 
          have been pledged as collateral securing a $5,000,000 line of 
          credit and a $4,000,000 short term note.

     PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost and depreciated on a 
          straight-line basis for financial reporting purposes over estimated 
          useful lives of 14-20 years for flight equipment and 3-10 years for 
          other property and equipment. Leasehold improvements are amortized 
          over the shorter of the life of the lease or the life of the asset. 
          Accelerated methods of depreciation are used for tax reporting 
          purposes. All owned aircraft are pledged to collateralize 
          outstanding obligations.

     Maintenance and repairs, including periodic aircraft overhauls, are 
          expensed as incurred.

     OTHER ASSETS

     Approximately $1,475,500 and $1,800,000 of long-term deposits on 
          aircraft operating leases at December 31, 1997 and 1996, 
          respectively, were included in other assets.

                                      34                           (Continued)

     DEFERRED LEASE PAYMENTS

     During 1997, the Company failed to make scheduled payments on several 
          leases and subsequently renegotiated substantially all of their 
          lease agreements. The renegotiated leases contain higher monthly 
          payments and or longer payment terms than the original agreements. 
          The unpaid rentals have been accrued and expensed in the period to 
          which they related and are being amortized over the new lease terms 
          of the aircraft as a reduction in future operating costs.

     DEFERRED CREDITS

     The Company has received various incentives in the form of interest rate 
          subsidies and spares parts in connection with the acquisition of 
          new aircraft. Incentives, other than those related to certain 
          Brasilia Aircraft, which the Company intends to dispose (see note 
          2), are being amortized as a reduction of rent expense or interest 
          expense over the term of the related agreement.

     REVENUE RECOGNITION

     Passenger revenues are recorded as income when the respective services 
          are rendered. Liability for unused tickets issued by the Company is 
          recorded as unearned revenue. The Company also receives public 
          service subsidy revenues for serving certain communities that do 
          not generate sufficient traffic to fully support profitable air 
          service, which are recorded as income as the agreed upon air 
          service is furnished by the Company.

     FREQUENT FLYER AWARDS

     The Company operates under a code-sharing agreement with United, and 
          participates in its frequent flyer program. The Company has not 
          deferred any revenue or accrued for incremental costs for mileage 
          accumulation relating to these programs, as the impact has not been 
          material.

     INCOME TAXES

     The Company accounts for deferred income taxes under the liability 
          method. Under this method, deferred tax assets and liabilities are 
          recognized for differences in the financial statement carrying 
          values of assets and liabilities and their respective tax bases at 
          tax rates expected to be in effect when the temporary differences 
          reverse.

     LOSS PER SHARE

     Statement of Financial Accounting Standards No. 128, "Earnings Per 
          Share" was adopted by the Company effective December 31, 1997. This 
          statement replaces the primary and fully diluted earnings per share 
          (EPS) disclosures with basic and diluted EPS disclosures.

                                      35                           (Continued)

     LOSS PER SHARE, CONTINUED

     Basic earnings per share amounts are computed by dividing net earnings 
          by the weighted average number of common shares outstanding during 
          the year. Diluted earnings per share amounts are computed by dividing
          net loss by the weighted average number of shares and all dilute 
          potential shares outstanding during the year. Since the Company has 
          suffered net losses in each of the three years ended December 31, 
          1997, 1996 and 1995, the adoption of SFAS 128 did not effect 
          previously reported loss per share data (basic). Diluted per share 
          amounts are not presented as the consideration of potential shares 
          would have reduced the reported losses per share. See notes 6 and 8 
          for a description of certain warrants and stock options which could 
          materially effect earnings per share in the future.

     STOCK OPTIONS

     The Company accounts for employee stock options using the intrinsic value 
          method prescribed under Accounting Principles Board Opinion No. 25, 
          "Accounting for Stock Issued to Employees." (APB No. 25).

     USE OF ESTIMATES

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

     FAIR VALUE OF FINANCIAL INSTRUMENTS

     Unless otherwise indicated, the carrying amounts of the Company's 
          financial instruments approximate fair value.

     RECLASSIFICATIONS

     Certain balances in the 1996 and 1995 financial statements have been 
          reclassified to conform with the 1997 presentation. These 
          reclassifications had no effect on net loss or stockholders' equity 
          as previously reported.

     The above table does not include two Brasilia aircraft that were returned 
          to the lessor in 1997, as discussed in the following paragraphs. As 
          discussed in note 2, the Company has determined that the seven 
          Brasilia aircraft (including the two that were returned to the lessor,
          discussed above) will not be needed to conduct operations in the 
          future, and the Company plans to dispose of such aircraft in 1998.

     During 1995, the Company and Raytheon amended the terms of certain 
          aircraft lease agreements which were recorded by the Company as 
          capital leases. Under the terms of then new amended agreements, these 
          leases met the criteria for treatment as operating leases. The gain 
          resulting from these transactions was not material. As discussed in 
          the following paragraphs, these agreements were again amended in 1997.

     Since January 1, 1996, the Company has taken delivery of ten new 
          Beechcraft 1900D aircraft. All of these aircraft had been initially 
          financed by the manufacturer under 14-1/2 year operating leases. As 
          discussed in the following paragraphs, the agreements were amended in 
          1997. In connection with the lease of these new Beechcraft 1900D 
          aircraft, the Company acquired the right to sell Raytheon certain 
          Beechcraft 1900C aircraft at prices equal to the balance owed on the 
          aircraft.

     During 1996, the Company sold eight aircraft to Raytheon and leased them 
          back under 12-year operating leases with an option to return upon 
          30-day notice during the first two years. Gains and losses on these 
          transactions were amortized over the first two years of the lease 
          agreement because that was the maximum term for which the Company 
          expected to retain the aircraft. Seven of the aircraft were returned 
          to Raytheon in 1996 and 1997. The remaining aircraft was destroyed 
          in November 1996.

     During 1997, the Company renegotiated 17 operating lease agreements under 
          which the Company failed to make timely lease payments to Raytheon. 
          The new lease agreements have terms ranging from 7-1/2 years to 15 
          years. The new lease agreements generally require higher monthly 
          lease payments than the previous lease agreements. The unpaid rentals 
          due at the time the leases were re-negotiated have been accrued and 
          expensed in the 1997 financial statements and are being amortized 
          over the term of the new agreements to offset the effect of the 
          higher future lease payments. The transaction did not result in a 
          gain or loss

     During 1997, the Company sold eleven aircraft to Raytheon and 
          leased them back under operating leases with various terms 
          ranging from 8-1/2 years to 18 years. The gains and losses on 
          these transactions are being amortized over the term of the 
          lease agreements.

     During 1997, the Company sold two Beechcraft 1900C aircraft to 
          Raytheon for an aggregate sale price of $5.8 million 
          representing the balance owed on the aircraft. The aircraft 
          were then purchased by a related party of the Company, 
          re-leased under monthly operating lease agreements by the 
          Company providing for monthly payments of $22,000 per aircraft 
          and subsequently sub-leased to a third party under a short term 
          lease agreement with the same terms as the lease. The sub-lease 
          agreements expire in 1998.

     During 1997, the Company sold a Beechcraft 1900C that had 
          previously been pledged as additional collateral under a lease 
          agreement with a third party which covers two of its Brasilia 
          aircraft. The proceeds from the sale were used to purchase a 
          certificate of deposit which is pledged as collateral for the 
          Brasilia lease. In the first quarter of 1998, the Company 
          entered into an agreement with the lessor to terminate the 
          Brasilia aircraft lease. A substantial portion of the 
          certificate of deposit will be used to pay the lease 
          termination costs. The lease termination costs have been 
          accrued and reflected in the 1997 financial statements (see 
          note 2).
  
     The Company has returned two Brasilia aircraft to a lessor in June 
          1997. In addition the Company has entered into a short term 
          note agreement in August 1997 with the lessor which covered 
          unpaid rentals due at that time. In 1998, the Company's lease 
          agreement was terminated, the Company is currently in 
          negotiation with the lessor in respect to unpaid rentals, lease 
          termination costs and the outstanding balance of a short term 
          note agreement. The Company has accrued its best estimate of 
          those costs in the 1997 financial statements. Actual results of 
          these ongoing negotiations of the lease termination could differ 
          materially from these estimates.
  
     As of December 31, 1997 lease commitments for aircraft were as 
          follows:

(A)  The Company entered into a short term note with Raytheon in July 1997 
     which has been extended to June 30, 1998. The interest rate is 
     variable and based on the prime lending rate, which at December 31, 
     1997 was 8.50 percent. The note is secured by accounts receivable and 
     Beech aircraft spare parts and equipment and is cross collaterialized 
     with the other Raytheon agreements.

(B)  The Company entered into a $2.5 million line of credit with Raytheon, 
     that was later amended to increase to a $5.0 million line of credit 
     in August 1996. The line of credit expired on March 31, 1997, and has 
     been extended to June 30, 1998. The line of credit is due upon demand. 
     The interest rate is variable and based on the prime lending rate, 
     which at December 31, 1997 and 1996 was 8.50 percent and 8.25 percent, 
     respectively. The note is secured by accounts receivable and Beech 
     aircraft spare parts and inventory and is cross collaterialized with 
     the other Raytheon agreements.

(C)  Various other short term notes consist of various trade notes, various 
     lease payment default notes and related party notes in 1997, and various 
     trade notes in 1996. During 1997 and 1996, the Company converted 
     approximately $1.8 million each year in trade payables to short term 
     notes. The notes require monthly payments and are due in 1998. The 
     interest rates vary with the a maximum interest rate of 10.5 percent. The 
     notes are unsecured. The related party note is payable to an entity 
     controlled by the majority shareholder, and is due upon demand with 
     interest at 12 percent.

     (D) The Raytheon notes consist of eight term notes in 1997 and twenty 
         nine term notes in 1996. As discussed in note 5, many of the term 
         notes outstanding at December 31, 1996 were repaid in connection 
         with sale-leaseback transactions in 1997. Additionally all of the 
         remaining notes were amended in 1997 due to payment defaults by the 
         Company. The notes require monthly payments through October 2006. 
         The interest rates on all of the remaining note agreements, after 
         the amendments, are 7.50 percent at December 31, 1997 and ranged 
         from 6.60 percent to 9.0 percent at December 31, 1996. The notes are 
         collateralized by aircraft.

     (E) Other long term notes consist of three term notes in 1997 and 1996. 
         The notes require monthly or quarterly payments through July 2007. 
         The interest rates on the notes are approximately 9.05 percent at 
         December 31, 1997 and 1996, respectively. The notes are 
         collateralized by aircraft.

       The Company's aircraft note agreements contain restrictive covenants 
         with which the Company must Comply. The Company was in compliance 
         with these covenants at December 31, 1997.

       In connection with the refinancing of the Company's long-term notes, 
         short term note agreements, and the restructuring of the Company's 
         lease agreements, the Company issued Raytheon a warrant to purchase 
         one million shares of the Company's stock, at the then current 
         market price of the stock. The warrant is exercisable for ten years 
         beginning July 16, 1998 at a price of $.75 per share. Accordingly, 
         the Company has recorded a discount equal to the estimated fair 
         value of the warrant on the date of issuance ($650,000), which is 
         being amortized as additional interest expense over the weighted 
         average life of the debt and lease agreements to which it relates. 
         As of December 31, 1997, the remaining unamortized discount is 
         $617,500, and is included above as a component of long-term debt.

       The fair value of the Company's debt instruments at December 31, 1997 
         and 1996, are not reasonably determinable considering the financial 
         condition of the Company.

(8)  EMPLOYEE BENEFIT PLANS

     401(k)

     The Company maintains a qualified 401(k) employee savings plan for the 
          benefit of substantially all employees. The Company matches up to 
          4 percent of participating employees' contributions. Company 
          contributions totaled $276,000 in 1997, $316,000 in 1996, and 
          $260,000 in 1995.

     STOCK OPTION PLANS

     In November 1993, the Company adopted The Great Lakes Aviation, Ltd. 
          1993 Stock Option Plan and the 1993 Director Stock Option Plan (the 
          Plans). Under the Plans, options to purchase an aggregate of not 
          more than 600,000 shares of common stock may be granted from time 
          to time to key employees, officers, and directors of the Company.

     On May 19, 1995, the board of directors passed a resolution offering all 
          employee option holders the option to reprice their current options 
          at the then market price ($3.88) in exchange for 30 percent of 
          their options. This offer was accepted by all employee stock option 
          holders. The exercise dates were adjusted to reflect this change.

     The Company accounts for the Plans under APB No. 25, under which no 
          compensation cost has been recognized. Had compensation cost for 
          the Plans been determined consistent with SFAS 123, the Company's 
          pro forma net loss and loss per share would not have been 
          materially different from its historical amounts.

     EMPLOYEE STOCK PURCHASE PLAN

     The Company maintains an employee stock purchase plan. Under the plan, 
          certain employees are eligible to purchase an aggregate of not more 
          than 125,000 shares of the Company's common stock at 95 percent of 
          the lower of the fair market value at the beginning or the end of 
          the calendar year in which the shares are purchased. In 1998 and 
          1997, 1,722 and 2,795 shares were purchased with 1997 and 1996 
          payroll withholdings, respectively.

(9)  COMMITMENTS AND CONTINGENCIES

     In connection with the acquisition of the Brasilia aircraft, the 
          Brazilian government has provided a financing subsidy to the 
          Company in the form of semiannual payments directly to the Company. 
          The Company has deferred those payments and amortized the payments 
          over the term of the financing on a straight-line basis. For those 
          seven Brasilia aircraft which the Company intends to dispose, the 
          remaining deferred amount related to those aircraft was included as 
          a reduction of the net book value of the owned Brasilia aircraft 
          and as a reduction the estimated lease termination costs on leased 
          Brasilia aircraft. The Company expects that it will transfer the 
          right to receive future subsidy payments in connection with the 
          sale of aircraft or termination of leases. The remaining subsidy 
          payments are not collateralized or otherwise secured against the 
          credit risk of the Brazilian government.

     The Company leases certain small aircraft used in its charter 
          operations. Beginning in December 1994, two Beechcraft Model 1900 
          19-passenger aircraft used in airline operations were financed 
          under operating leases from a company owned by Great Lakes' 
          president and majority stockholder. Total payments under these 
          leases were $830,000 in 1997, $884,000 in 1996, and $844,000 in 
          1995.

     The FAA imposed penalties on the Company for non-compliance during the 
          shutdown which occurred in May 1997. These penalties total 
          $1,000,000, of which $700,000 has been suspended for the period of 
          12 calendar months from the date of the Consent Order, and shall be 
          waived if the Company complies with all the terms and conditions of 
          the Consent Order. The $300,000 minimum penalty has been expensed 
          during 1997. The remaining $700,000 has not been accrued as the 
          Company believes that it has and will comply with the Consent Order 
          for all relevant periods.

     NONAIRCRAFT LEASE COMMITMENTS

     The Company leases certain hanger and terminal facilities under 
          operating leases, which provide for approximate future minimum 
          lease payments, as follows:

     SLOT ALLOCATIONS

     On August 29, 1995, United exercised its contractual option and 
        effective October 29, 1995, purchased ten of the Company's landing 
        and takeoff slots at Chicago O'Hare airport for $3,850,000. The sale 
        of the slots resulted in a gain of $3,850,000 which was recorded in 
        the fourth quarter of 1995. These ten slots were the only slots owned 
        by the Company which were not encumbered by requirements to provide 
        essential air service to small communities. The Company had an 
        agreement to lease these slots from United for $11,000 per month 
        until May 1997. Thereafter, the Company has not paid any separate 
        consideration for the use of these slots.

     United has an option which expired concurrently with the United Express 
        Agreement in April 1997, which was extended on a monthly basis to 
        December 31, 1997, to acquire all or any portion of the Company's 
        slots for the lesser of their fair market value or certain 
        specified maximum prices set forth in the option agreement. United 
        did not exercise its option to purchase the slots prior to the 
        expiration of the United Express Agreement. The maximum aggregate 
        purchase price for the 54 slots was $26.2 million. United's 
        acquisition of the slots would be subject to the approval of the 
        U.S. Department of Transportation (DOT) and the assumption by 
        United of essential air service responsibility to certain communities. 
        In the event United acquires the slots, the Company has the right 
        to lease the slots from United for a period of one year thereafter.

     LITIGATION

     The Company is a defendant in a lawsuit arising from the collision of a 
        small aircraft with one of the Company's Beechcraft 1900 aircraft in 
        Quincy, Illinois on November 19, 1996. The collision occurred at the 
        intersection of two runways as the Company's aircraft was landing, 
        and resulted in the death of all ten passengers and the two crew 
        members. The Company's insurance carrier is providing for the Company's 
        defense in the lawsuit and the Company believes that all claims arising 
        from the accident will be adequately covered by insurance.

     The Company is a party to other ongoing legal claims and assertions 
        arising in the ordinary course of business. In the opinion of 
        management, the resolution of these matters will not have a material 
        adverse effect on the Company's financial position, results of 
        operations, or cash flows.

THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE 
NOT BEEN REGISTERED UNDER EITHER THE SECURITIES ACT OF 1933 OR APPLICABLE 
STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, OFFERED, 
PLEDGED OR OTHERWISE DISTRIBUTED FOR VALUE UNLESS THERE IS AN EFFECTIVE 
REGISTRATION STATEMENT UNDER SUCH ACT AND SUCH LAWS COVERING SUCH SECURITIES, 
OR THE COMPANY RECEIVES AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY 
STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT, OFFER, PLEDGE OR OTHER 
DISTRIBUTION FOR VALUE IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS 
DELIVERY REQUIREMENTS OF SUCH ACT AND SUCH LAWS.

                                                            DATE: JULY 23, 1998

                                    WARRANT

                        TO PURCHASE 1,000,000 SHARES OF
                                COMMON STOCK OF

                           GREAT LAKES AVIATION, LTD.

     THIS CERTIFIES THAT, for good and valuable consideration, RAYTHEON 
AIRCRAFT CREDIT CORPORATION (the "Holder") is entitled to subscribe for and 
purchase from Great Lakes Aviation, Ltd., an Iowa corporation (the 
"Company"), 1,000,000 fully paid and nonassessable shares of the Common Stock 
of the Company at a price per share equal to $0.75 (the "Warrant Exercise 
Price"), subject to the antidilution provisions of this Warrant.  The shares 
which may be acquired upon exercise of this Warrant are referred to herein as 
the "Warrant Shares."

     This Warrant is subject to the following provisions, terms and 
conditions:

     1.   EXERCISE.  This Warrant may be exercised, in whole but not in part, 
at any time after July 23, 1998 up to and including the tenth anniversary of 
the date hereof, after which date this Warrant shall expire.  To exercise 
this Warrant, the Holder shall deliver a written notice of exercise (in the 
form attached hereto) to the Company at the principal office of the Company 
and accompanied or preceded by the surrender of this Warrant along with a 
certified or cashier's check in payment of the Warrant Exercise Price for 
such shares.

     2.   ISSUANCE OF THE WARRANT SHARES.

     (a)  The Company agrees that the shares of Common Stock purchased hereby 
shall be and are deemed to be issued to the Holder as of the close of 
business on the date on which this Warrant shall have been surrendered and 
the payment made for such Warrant Shares as aforesaid.  Subject to the 
provisions of the next section, certificates for the Warrant Shares so 
purchased shall be delivered to the Holder within a reasonable time after the 
exercise hereof.

     (b)  Notwithstanding the foregoing, the Company shall not be required to 
deliver any certificate for Warrant Shares upon exercise of this Warrant 
except in accordance with registrations 

<PAGE>

under applicable securities laws or an opinion of counsel reasonably 
acceptable to it to the effect that an exemption from the applicable 
securities registration requirements is available.  Nothing herein, however, 
shall obligate the Company to effect registration under federal or state 
securities laws. If registration is not in effect and if the Company has not 
received an opinion of counsel reasonably acceptable to it to the effect that 
an exemption is available when the Holder seeks to exercise the Warrant, the 
Warrant exercise period will be extended, if need be, to prevent the Warrant 
from expiring, until such time as either registration becomes effective or 
the Company has received an opinion of counsel reasonably acceptable to it to 
the effect that an exemption is available, and the Warrant shall then remain 
exercisable for a period of at least 45 calendar days from the date the 
Company delivers to the Holder written notice of the availability of such 
registration or exemption.  The Holder agrees to execute such documents and 
make such representations, warranties, and agreements as may be required 
solely to comply with the exemptions relied upon by the Company, or the 
registrations made, for the issuance of the Warrant Shares.

     (c)  The Holder acknowledges and understands that (i) the Common Stock 
to be issued to Holder upon exercise of this Warrant will not be registered 
under the Securities Act of 1933 (the "Act") or any state securities laws; 
(ii) the Common Stock issued to Holder upon exercise of this Warrant will be 
subject to transfer restrictions under the Act and applicable state 
securities laws and may not be transferred unless (x) subsequently registered 
under the Act and applicable state securities laws or (y) there is delivered 
to the Company an opinion of counsel satisfactory to the Company that such 
registration is not required; and (iii) the Company will place a restrictive 
legend on the certificate(s) representing the Common Stock to be issued to 
Holder hereunder, containing the following language:

          THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED 
          WITHOUT REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS 
          AMENDED (THE "ACT") AND WITHOUT REGISTRATION UNDER 
          APPLICABLE STATE SECURITIES LAWS, IN RELIANCE UPON 
          EXEMPTIONS CONTAINED IN THE ACT AND SUCH LAWS.  NO 
          TRANSFER OF THESE SHARES OR ANY INTEREST THEREIN MAY BE 
          MADE EXCEPT PURSUANT TO EFFECTIVE REGISTRATION STATEMENTS 
          UNDER SAID LAWS UNLESS THIS CORPORATION HAS RECEIVED AN 
          OPINION OF COUNSEL SATISFACTORY TO IT THAT SUCH TRANSFER 
          OR DISPOSITION DOES NOT REQUIRE REGISTRATION UNDER SAID 
          LAWS AND, FOR ANY SALES UNDER RULE 144 OF THE ACT, SUCH 
          EVIDENCE AS IT SHALL REQUEST FOR COMPLIANCE WITH THAT 
          RULE.

Upon written request, the Company agrees to issue to Holder a replacement 
stock certificate without such legend upon the expiration of the restrictions 
imposed by Rule 144.

     3.   COVENANTS OF THE COMPANY.  The Company covenants and agrees that 
all Warrant Shares will, upon issuance, be duly authorized and issued, fully 
paid, nonassessable, and free from all taxes, liens, and charges with respect 
to the issue thereof.  The Company further covenants and agrees that during 
the period within which the rights represented by this Warrant may be 
exercised, the Company will at all times have authorized and reserved for the 
purpose of issue upon exercise of this Warrant a sufficient number of shares 
of Common Stock to provide for the exercise of the rights represented by this 
Warrant.

                                       2
<PAGE>

     4.   ANTIDILUTION ADJUSTMENTS.  The provisions of this Warrant are 
subject to adjustment as provided in this Section 4.

     (a)  The Warrant Exercise Price shall be adjusted from time to time such 
that in case the Company shall hereafter:

          (i)   pay any dividends with respect to its Common Stock payable 
     in any class of stock or securities convertible into any class of stock 
     of the Company;

          (ii)  subdivide its then outstanding shares of Common Stock into a 
     greater number of shares; or

         (iii)  combine outstanding shares of Common Stock, by reclassification 
     or otherwise;

then, in any such event, the Warrant Exercise Price in effect immediately 
prior to such event shall (until adjusted again pursuant hereto) be adjusted 
immediately after such event to a price (calculated to the nearest full cent) 
determined by dividing (a) the total number of shares of Common Stock 
outstanding immediately prior to such event (including the maximum number of 
shares of Common Stock issuable in respect of any securities convertible into 
Common Stock but excluding any options or warrants to acquire Common Stock), 
multiplied by the then existing Warrant Exercise Price, by (b) the total 
number of shares of Common Stock outstanding immediately after such event 
(including the maximum number of shares of Common Stock issuable in respect 
of any securities convertible into Common Stock but excluding any options or 
warrants to acquire Common Stock), and the resulting quotient shall be the 
adjusted Warrant Exercise Price per share.  An adjustment made pursuant to 
this subsection shall become effective immediately after the record date in 
the case of a dividend or distribution and shall become effective immediately 
after the effective date in the case of a subdivision, combination or 
reclassification. If, as a result of an adjustment made pursuant to this 
subsection, the Holder of this Warrant is entitled to receive shares of two 
or more classes of capital stock, the Board of Directors (whose determination 
shall be conclusive) shall determine the allocation of the adjusted Warrant 
Exercise Price between or among shares of such classes of capital stock.  All 
calculations under this subsection shall be made to the nearest cent or to 
the nearest 1/100 of a share, as the case may be.  In the event that at any 
time as a result of an adjustment made pursuant to this subsection, the 
Holder of this Warrant is entitled to receive any shares of the Company other 
than shares of Common Stock, the Warrant Exercise Price of such other shares 
so receivable upon exercise of this Warrant shall be subject to adjustment 
from time to time in a manner and on terms as nearly equivalent as 
practicable to the provisions with respect to Common Stock contained in this 
Section.

     (b)  Upon each adjustment of the Warrant Exercise Price pursuant to 
Section 4(a) above, the Holder of this Warrant shall thereafter (until 
another such adjustment) be entitled to purchase at the adjusted Warrant 
Exercise Price the number of shares, calculated to the nearest full share, 
obtained by multiplying the number of shares specified in this Warrant (as 
adjusted as a result of all adjustments in the Warrant Exercise Price in 
effect prior to such adjustment) by the Warrant Exercise 

                                       3
<PAGE>

Price in effect prior to such adjustment and dividing the product so obtained 
by the adjusted Warrant Exercise Price.

     (c)  In case of any consolidation or merger to which the Company is a 
party other than a merger or consolidation in which the Company is the 
continuing corporation (provided that the Company's then outstanding shares 
are not converted into securities of another corporation or cash), or in the 
case of any statutory exchange of securities with another corporation 
(including any exchange effected in connection with a merger of a third 
corporation into the Company), there shall be no adjustment under subsection 
(a) of this Section above but the Holder of this Warrant shall have the right 
thereafter to convert such Warrant into the kind and amount of shares of 
stock and other securities and property which he, she or it would have owned 
or have been entitled to receive immediately after such consolidation, merger 
or statutory exchange had such Warrant been converted immediately prior to 
the effective date of such consolidation, merger or statutory exchange.  The 
provisions of this subsection shall similarly apply to successive 
consolidations, mergers or statutory exchanges.

     (d)  Upon any adjustment of the Warrant Exercise Price, then and in each 
such case, the Company shall give written notice thereof, by first-class 
mail, postage prepaid, addressed to the Holder as shown on the books of the 
Company, which notice shall state the Warrant Exercise Price resulting from 
such adjustment and the increase or decrease, if any, in the number of shares 
of Common Stock purchasable at such price upon the exercise of this Warrant, 
setting forth in reasonable detail the method of calculation and the facts 
upon which such calculation is based.

     5.   NO VOTING RIGHTS.  This Warrant shall not entitle the Holder to any 
voting rights or other rights as a shareholder of the Company.

     6.   FRACTIONAL SHARES.  Fractional shares shall not be issued upon the 
exercise of this Warrant, but in any case where the Holder would, except for 
the provisions of this Section, be entitled under the terms hereof to receive 
a fractional share, the Company shall, upon the exercise of this Warrant for 
the largest number of whole shares then called for, pay a sum in cash equal 
to the fair market value of such fractional share.

     7.   CALL PROVISION.  At any time prior to the exercise of this Warrant, 
the Company may, at its option, deliver a written notice to the registered 
Holder hereof (the "Call Notice"), which shall be sent via certified mail, 
return receipt requested, and shall be effective as of the date of mailing. 
Upon delivery of the Call Notice this Warrant shall not be exercisable and 
within 10 days after the date of the Call Notice the Company shall purchase 
and the Holder of this Warrant shall sell this Warrant to the Company at a 
price (the "Warrant Purchase Price") equal to ninety percent (90%) of the 
product of (i) the number of shares of Common Stock issuable upon exercise of 
this Warrant, multiplied by (ii) the difference between (x) the Reported Last
