                                     PART I

ITEM 1.  BUSINESS

     A. General

     Whitehall Corporation ("Whitehall" or the "Company") is an independent
provider of maintenance and modification services for commercial, military and
freighter aircraft. The Company focuses primarily on two categories of
commercial customers: established traditional commercial carriers that view
outsourcing as a way to reduce operating expenses and increase their
competitiveness and new entrant, low-cost air carriers that rely on outsourcing
for scheduled heavy maintenance The Company operates two United States Federal
Aviation Administration ("FAA") and Joint Aviation Authority of the European
Economic Community ("JAA") certified repair stations that specialize in heavy
maintenance and modification of Boeing 707, 727, 737, McDonnell Douglas DC-8,
DC-9, DC-10 and Lockheed L-100, L-188 and C-130 aircraft. The Company offers its
customers a comprehensive range of aviation services, including scheduled "A,"
"B," "C" and "D" level inspections, block overhauls and repairs, corrosion
prevention and control programs and exterior stripping and painting.
Modification services provided by the Company include interior reconfiguration,
cargo conversions and avionics installations. Through a joint venture, the
Company also designs, and markets hushkits designed to reduce the noise created
by Boeing 737-100 and 737-200 series aircraft to levels which comply with
FAA-mandated Stage 3 noise reduction standards. The Company was incorporated
under the laws of Delaware in 1963 as a successor to a Minnesota corporation
organized in 1960.

     B. Significant Developments

     On March 24, 1998, the Company entered into a definitive merger agreement
(the "Merger Agreement") with Aviation Sales Company ("AVS") pursuant to which a
wholly-owned subsidiary of AVS will merge (the "Merger") with and into the
Company. As a result of the Merger, the Company will become a wholly owned
subsidiary of AVS. The Merger is expected to be accounted for as a pooling of
interests. Under the terms of the Merger Agreement, each share of the Company's
common stock outstanding at the effective time of the Merger will be converted
into the right to receive .5143 shares of common stock of AVS. Consummation of
the Merger, which is expected to occur at the end of the second quarter of 1998,
is subject to customary closing conditions, including, without limitation,
approval of the Company's and AVS's stockholders and successful completion of
regulatory review under the Hart-Scott-Rodino Antitrust Improvements Act. No
assurance can be given that the Merger will ultimately be consummated or that it
will be consummated on the terms set forth in the Merger Agreement.

     In July 1997, the Company purchased from Zantop International Airlines,
Inc. ("Zantop") certain assets (the "Acquired Assets") used in connection with
the operation of Zantop's third party aircraft maintenance business located in
Macon, Georgia. Among the Acquired Assets were all of the Zantop's leasehold
interests in the properties located at its Macon facility (the "Leased
Facilities"). The purchase price for the Acquired Assets was $1.5 million in
cash plus the assumption of certain liabilities, including approximately $4.3
million in future lease obligations relating to the Leased Facilities.

     In April 1997, the United States Air Force ("USAF") awarded the Company a
five-year contract (the "C-130 Contract") to perform Programmed Depot
Maintenance on its fleet of C-130 cargo aircraft stationed in the continental
United States. In June 1997, the C-130 Contract was cancelled at the convenience
of the U.S. government because the USAF elected to perform this work with
government personnel at two of its remaining USAF bases rather than outsourcing
it to private contractors. The C-130 Contract provides for reimbursement by the
USAF of costs incurred by the Company during its term. The Company has made a
claim for reimbursement and is currently negotiating a settlement with the USAF
for the claimed amount.

     In March 1997, the Company sold its electronics business to a private
investor group (the "Crystek Buyer") for approximately $2.7 million. The
transaction was structured as a sale by the Company of all of the outstanding
capital stock of Crystek Crystals Corporation, the Company's electronics
division operating subsidiary ("Crystek"). The Company received approximately 
$1.9 million in cash and two promissory notes aggregating $864,000. The
promissory notes are due in installments from 1998 through 2001 and bear
interest at a rate of 10% per annum. Under the terms of the agreement


                                       -2-


<PAGE>   3

relating to the sale of Crystek (the "Crystek Agreement"), the Company agreed to
remediate certain environmental conditions on the real property owned by Crystek
(the "Crystek Property") and, if such environmental conditions are not
satisfactorily remediated by December 31, 1998, the Crystek Buyer has the right
to require the Company to repurchase the Crystek Property on the terms and
subject to the conditions set forth in the Crystek Agreement. In the event of
such a sale, the Crystek Buyer will have the right to lease the Crystek Property
from the Company.

     In November 1996, the Company sold its ocean systems business to a
newly-formed company, Hydroscience Technologies, Inc. ("HTI"), in exchange for
818,182 shares of preferred stock of HTI (the "HTI Preferred Stock") and the
limited assumption by HTI of potential warranty liabilities associated with such
business. The aggregate amount of HTI Preferred Stock received by the Company
was equal to the book value of the assets transferred by it to HTI. The HTI
Preferred Stock carries a liquidation preference of $5.50 per share. At the
Company's election, the HTI Preferred Stock is convertible into 45% of the
common stock of HTI. The Company has concluded that the value of its investment
in the HTI Preferred Stock has declined permanently. The entire amount was
written off in September 1997.

     C. Financial Information about Industry Segments

     During 1997, the Company operated in two business segments: aircraft
maintenance and electronics. During 1996, the Company also operated in the ocean
systems business. A table presenting selected financial information attributable
to each of the principal industry segments in which the Company operated is set
forth in Note N of the Notes to the Consolidated Financial Statements filed
under Item 8 in Part II of this Annual Report on Form 10-K.

     As described in Item 1(B) above, the Company sold its ocean systems
business in November 1996 and its electronics business in March 1997. As a
result, the Company operates exclusively in the aviation maintenance industry.

     D. Narrative Description of the Business

INDUSTRY OUTLOOK

     General. The Company believes that the total market for commercial airframe
heavy maintenance and modification services in North America is approximately
$2.3 billion annually. Approximately 65% of these services are currently being
performed by airlines themselves, with the remaining demand being outsourced to
independent providers such as the Company. As the commercial airline industry
continues to operate under intense competition and federal budgetary constraints
force reductions in military spending, management believes that both the private
and military sectors will increasingly view outsourcing as a logical and
effective way to reduce operating cost. Factors which management believes
indicate the strength of the demand for its services include (i) the projected
growth of worldwide air traffic, (ii) the proliferation of start-up airlines
which typically depend on outside facilities for maintenance, (iii) the desire
of established airlines to reduce costs by divesting themselves of large
segments of their maintenance operations and shifting these responsibilities to
third-party providers who are often able to provide these services more quickly
and less expensively; (iv) the growth of the worldwide air cargo industry which
the Company believes will foster the demand for passenger-to-freighter
modification services and (v) the current policy of the United States military
to promote outsourcing to the private sector many of the services that were
traditionally provided internally.

     Commercial Maintenance Market. The growth of the worldwide commercial
aircraft maintenance market is greatly affected by worldwide air travel.
According to Boeing's 1997 Current Market Outlook (the "Boeing Report"), world
air travel is expected to grow at a compound annual rate of 5.5% for the next
ten years. During that same period, the worldwide fleet of commercial airplanes
is expected to double. Further, deregulation of the aviation industry in the
United States and the European Economic Community, increased demand for low-fare
air travel and relatively low barriers to entry have led to the emergence of
several start-up airlines. Approximately 92% of the aircraft operators worldwide
have fleets of less than 30 aircraft. For these carriers, in-house maintenance
capabilities are not generally considered to be economically viable. In
addition, a number of established airlines have begun to view maintenance
outsourcing as a way to increase productivity of their assets, reduce operating
costs and better focus their resources on their core competencies of
transporting passengers and freight.

     Commercial Modification Market. The Company expects the airframe
modification business to experience growth over the next several years,
primarily due to the rapid expansion of the global air freight industry and the
phase in of federal noise control legislation requiring airlines to either
modify or remove from their U.S. fleet certain aircraft models


                                       -3-


<PAGE>   4







by the end of 1999. As the worldwide freight transport market continues to grow,
so does the demand for dedicated cargo aircraft. According to the Boeing Report,
air cargo traffic is projected to increase at a compound annual rate of 6.6%
through 2016 and an additional 420 dedicated freighter aircraft are expected to
be added to the world fleet during that period. Because few cargo carriers are
willing to commit the capital to purchase newly built cargo aircraft, it is
expected that the majority of the dedicated freighter aircraft coming into
circulation in the next several years will be passenger aircraft which have been
modified and converted for cargo duty.

     The Airport Noise and Capacity Act of 1990 ("ANCA") requires the phaseout
of Stage 2 aircraft (defined as aircraft that comply with the Stage 2 noise
levels prescribed in Part 36 of the Federal Aviation Regulations) by December
31, 1999, subject to certain exceptions. The FAA regulations which implement the
ANCA require carriers to modify or reduce the number of Stage 2 aircraft
operated by 75% by the end of 1998 and 100% by the end of 1999. Alternatively, a
carrier could satisfy these compliance requirements by phasing in aircraft
meeting the stricter Stage 3 requirements (set forth in Part 36 of the Federal
Aviation Regulations) so that its fleet has at least 75% Stage 3 aircraft by the
end of 1998 and 100% of Stage 3 aircraft by the end of 1999. Certain types of
Stage 2 aircraft can be modified to meet Stage 3 requirements by installing a
hushkit to the aircraft's engine. AvAero Noise Reduction Joint Venture
("AvAero"), a joint venture in which the Company holds a 40% interest, designs
and markets FAA-certified hushkits for Boeing 737-100 and 737-200 series
aircraft. AvAero's other venturers are Avro Corp., which holds a 40% interest,
and WDW Aviation Management, Inc., which holds a 20% interest.

MILITARY MAINTENANCE AND MODIFICATION MARKET. The U.S. military has also turned
to outsourcing in an effort to reduce costs in a shrinking budgetary
environment. Currently, U.S. military and government civilian personnel perform
approximately 72% and 64% of the aircraft maintenance for the USAF and United
States Navy ("Navy"), respectively. Several factors suggest that a greater
percentage of this work may be outsourced in the future. Budget constraints have
lead to a reduction in the number of military and government civilian personnel
in each branch of the U.S. military. The Navy is considering closing three of
its six naval aviation depots, however the number of its aircraft to be
maintained is expected to be reduced by only 25%. The USAF has moved to
"privatize in place" rather than close down its Kelly and McClellen bases.
Private contractors have submitted proposals to perform the work on site at
these bases and to employ many of the former government workers. The reduction
in the government's internal capacity to provide military aircraft maintenance
and modification services has not been accompanied by a corresponding reduction
in demand for these services. The current U.S. policy favoring the rapid
deployment of forces as opposed to maintaining numerous overseas military bases
relies heavily on the ability to quickly airlift personnel and equipment to
areas requiring military or humanitarian intervention. Accordingly, the need for
maintenance, modification and life extension programs for a substantial portion
of the U.S. military air fleet is expected to continue. Under the so-called
"60-40 law," the military was limited in the amount of depot level aircraft
maintenance work it was permitted to transfer to the private sector to 40% of
its overall depot level maintenance requirements. On November 18, 1997, the
National Defense Authorization Act for Fiscal 1998 increased this amount to 50%.
Although the recent change in law and current trend towards outsourcing by the
U.S. military should result in greater opportunities for independent maintenance
providers such as the Company, there can be no assurance that the Company will
be successful in obtaining any future U.S. military contracts.

Principal Products And Services

     Commercial Maintenance Services. The principal services performed by the
Company are scheduled "A," "B," "C" and "D" level maintenance checks. Each
involves a different degree of inspection and the services performed at each
level vary depending upon the individual aircraft operator's FAA-certified
maintenance program. The "A" and "B" level checks involve the fewest required
procedures and often can be completed within a few days. The "C" and "D" level
checks are more comprehensive and usually take several weeks to complete,
depending upon the scope of the work to be performed.

     The "C" level check is an intermediate level service inspection that
typically includes a thorough cleaning of the aircraft's exterior, testing and
lubrication of its operational systems, filter servicing and limited cleaning
and servicing of the interior. Trained mechanics perform a visual inspection of
the external structure and internal structure through access panels. The "D"
level check includes all of the work accomplished in the "C" level check but
places a more detailed emphasis on the integrity of the systems and structural
functions. In the "D" level check, the aircraft is disassembled to the point
where the entire structure can be inspected and evaluated. Once the evaluation
and repairs are completed, the aircraft and its systems are reassembled to the
detailed tolerances demanded in each system's specifications. Depending upon the
type of aircraft and the FAA-certified maintenance program being followed,
intervals between "C" level checks can range from 1,000 to 5,000 flight hours
and intervals between "D" level checks can range from 10,000 to 25,000 flight
hours.




                                       -4-


<PAGE>   5







     Structural inspections performed during "C" level and "D" level checks
provide Company personnel with detailed information about the condition of the
aircraft and the need to perform additional work or repairs not provided for in
the original workscope. Project coordinators and customer support personnel work
closely with the aircraft's customer service representative in evaluating the
scope of any additional work required and in the preparation of a detailed cost
estimate for the labor and materials required to complete the job. Upon receipt
of the customer representative's approval of the estimate, the Company releases
the requisitions and work orders into the work flow for the aircraft.

     Other maintenance services offered to commercial customers include
Supplemental Structure Inspections ("SSI's") and Corrosion Prevention and
Control Programs ("CPCP's"). SSI's are structural inspections which focus on
known problem areas and are required by most aircraft manufacturers. CPCP's are
also an outgrowth of manufacturer-required Aging Aircraft Programs and involve
the inspection and treatment of areas with known corrosion problems. These
additional inspections often supplement the "C" and "D" level check tasks.

     Commercial Modification Services. Each aircraft certified by the FAA is
constructed under a "Type Certificate." Anything which is done subsequently to
modify the aircraft from its original specifications requires the review,
flight-testing and approval of the FAA which is evidenced by the issuance of a
Supplemental Type Certificate ("STC") for that particular modification. Typical
modification services performed by the Company include refurbishing and
reconfiguring passenger seating, installing passenger amenities such as
telephones and video screens and converting traditional passenger cabins into
amenity filled "VIP" quarters.

     The process of converting a passenger plane to freighter configuration
entails completely stripping the interior; strengthening the load-bearing
capacity of the flooring; installing the bulkhead or cargo net; cutting into the
fuselage for the installation of a large cargo door; reinforcing the surrounding
structures for the new door; replacing windows with metal plugs; and fabricating
and installing the cargo door itself. The aircraft interior may also need to be
lined to protect cabin walls from pallet damage and the air conditioning system
may have to be modified. Conversion contracts also typically require "C" or "D"
level maintenance checks as these converted aircraft have often been out of
service for some time and maintenance is required for the aircraft to comply
with current FAA standards.

     The Company owns a 40% interest in AvAero, a joint venture that designs and
markets hushkits for Boeing 737- 100 and 737-200 series aircraft. The AvAero
hushkit weighs approximately 500 pounds at its heaviest configuration and fits a
wide range of engine models and aircraft weights. Major airlines have cited its
design simplicity, ease of installation, performance and absence of operational
restrictions as major factors in selecting the AvAero hushkit over competing
models. In January 1997, AvAero was selected by Southwest Airlines ("Southwest")
to provide hushkits for up to 34 of Southwest's Boeing 737 aircraft. The
agreement with Southwest provides for the delivery of 20 hushkits beginning in
June 1997 and an option to purchase an additional 14 hushkits.

     Additional modification services performed by the Company include cockpit
reconfiguration and the integration of Traffic Control and Avoidance Systems
("TCAS"), windshear detection systems and navigational aids.

     Military Maintenance and Modification Services. The Company provides
aircraft maintenance and modification services to the U.S. military and the
military branches of certain foreign governments. The Company specializes in
providing Programmed Depot Maintenance ("PDM") on large transport planes used to
move troops, supplies and equipment, such as the C-130 "Hercules." The PDM
program involves a nose to tail inspection and repair program. It begins with
the defueling of the aircraft and the stripping of its exterior paint. Trained
mechanics then perform a section-by-section structural examination of the entire
aircraft which can result in modifications to the airframe. Avionics are
inspected and repaired, replaced or modified as needed. Corrosion prevention and
control measures and various system overhauls or upgrades may also be performed.
At the completion of the overhaul, the aircraft is repainted.

     On April 15, 1997, the Company was awarded the C-130 Contract by the USAF.
It provided for the furnishing of PDM on the USAF's C-130 aircraft stationed in
the continental United States. In June 1997, the C-130 Contract was cancelled at
the convenience of the U.S. government because the USAF elected to perform this
work with government personnel at two of its remaining USAF bases rather than
outsourcing it to private contractors. The C-130 Contract provides for
reimbursement by the USAF of costs incurred by the Company during its term. The
Company has made a claim for reimbursement and is currently negotiating a
settlement with the USAF for the claimed amount.



                                       -5-


<PAGE>   6
     The Company is currently performing C-130 PDM work for the government of
Mexico and continues to bid for similar work for aircraft owned and operated by
certain other foreign governments.

PRICING

     The Company's services are offered to commercial customers on a contract
basis. Customers are generally offered either time and material based
arrangements or flat rate fixed price arrangements. Under the time and materials
fee arrangement, customers receive a detailed price estimate and condition
report from the Company after a thorough inspection of the aircraft. Following
the approval by the customer of the estimate, the Company issues work orders and
requisitions for the customer's aircraft. Customer support personnel closely
monitor the progress of the aircraft and negotiate with the customer any
additional pricing, scheduling and logistical issues which arise during the
course of servicing. Most of the aircraft serviced by the Company are priced on
a time and material based arrangement.

     Under the flat rate fixed pricing contracts, the Company establishes a set
price prior to undertaking a maintenance or modification project based upon
estimates made either before or after inspection of the aircraft. The Company's
flat rate fixed price estimates made prior to inspection of an aircraft are
based upon standard labor and materials requirements and typically include
provisions for adjustments based upon condition of the aircraft.

     The U.S. military contracts for which the Company competes are awarded on a
competitive bid basis. The contracts are typically firm agreements to provide
specified aviation services at a fixed rate. They typically have terms of one
year subject to annual renewals at the option of the contracting agency.

MANAGEMENT INFORMATION SYSTEM

     The Company has developed an advanced integrated management information
system which allows management and customers to track the progress of every
aircraft being serviced on a real time basis. Bar coded work task cards are
tracked electronically and help coordinate the work of each assigned mechanic
and quality control inspector. The system can be accessed from any one of more
than 200 display stations located throughout the Company's Lake City and Macon
facilities. Project Coordinators can immediately access such detailed
information as the number of work-hours generated for any given project, a list
of all parts used or ordered and the identity of and tasks performed by each
mechanic and quality control inspector who has worked on an aircraft. This
information enables management to optimize the daily deployment of personnel,
materials and equipment among the various projects in service and to provide
customers with quick and accurate information about the status of their
aircraft.

COMPETITION

     The market for aircraft maintenance and modification services is highly
competitive and fragmented. In addition to several other independent maintenance
operators, the Company faces significant competition from major commercial
airlines that own and operate their own aircraft maintenance service centers. In
addition, the aircraft divisions of certain large original equipment
manufacturers ("OEM"s) have announced their intention to enter this market. Such
OEM's and airlines have substantially greater financial resources than the
Company. The Company does not have data available to determine its exact
relative market position. The Company believes that the most important bases for
competition in its industry are dependability of performance, prompt turnaround
time, price and flexibility. The Company considers its competitive strengths to
be the flexibility and experience of its labor force, its efficient facilities
and its reputation for quality and on-time delivery. The Company's principal
competitors for its commercial work include Tramco, Inc., Dee Howard Company,
Mobile Aerospace, Inc., Triad International Maintenance Corporation and Pemco
World Air Services, Inc. Its principal competitors for military contracts
include Boeing Military Aircraft, Lockheed-Martin Aeromod and Raytheon-E
Systems.

CUSTOMERS

     The Company's commercial services are offered to the airline industry at
large, and in particular, to owners and operators of aircraft who do not have
maintenance facilities of their own or whose facilities are unable to
accommodate an increasing workload. These customers have historically included
many start-up passenger airlines and air cargo companies. The Company's
customers also include large, established air carriers who have turned to
outsourcing




                                       -6-


<PAGE>   7

portions of their maintenance operations in an effort to increase their
profitability. During 1997, AirTran Holdings, Inc. (formerly, Valujet, Inc.)
accounted for approximately 23% of the Company's consolidated net sales, and the
top three customers of the Company (including AirTran) accounted for
approximately 49% of such sales. During 1996, three customers accounted for
approximately 26%, 15%, and 14% of the Company's consolidated net sales. During
1995, two customers accounted for 30% and 21% of the Company's consolidated net
sales. None of the Company's customers are contractually obligated to provide
the Company with any minimum number of aircraft for servicing in the future.
There can be no assurance that the Company's larger historical customers will
continue to utilize the Company's services to the same extent as they have in
the past. The Company's commercial customers include Continental Airlines,
American Trans Air, AirTran, Ryan International/Emery Worldwide, Burlington Air
Freight, and US Airways. The Company has also performed services under
government contracts for the USAF, the U.S. Coast Guard and the Mexican Air
Force. The U.S. government accounted for approximately 5% and 2% of the
Company's 1997 and 1995 consolidated net sales, respectively. The Company made
no sales to the U.S. government in 1996.

REGULATION AND CERTIFICATION

     The maintenance, modification and operation of aircraft are strictly
regulated by the FAA and foreign aviation authorities which oversee such matters
as aircraft certification, inspection, maintenance, certification of personnel
and record keeping. FAA regulations are designed to insure that all aircraft and
aviation equipment are continuously maintained in proper condition to ensure
safe operation of the aircraft. Similar rules apply in most foreign countries.
All aircraft must be maintained under a continuous monitoring program and must
periodically undergo thorough inspection and maintenance. The inspection,
maintenance and repair procedures for the various types of aircraft are
prescribed by regulatory authorities and can be performed only by certified
repair facilities utilizing certified technicians. The Company operates FAA-
certified repair stations in Lake City, Florida and Macon, Georgia and has been
granted licenses from the FAA and several foreign regulatory counterparts,
including the JAA, to perform maintenance, repair and overhaul services on most
narrow-bodied aircraft and wide-bodied aircraft. The Company also employs a
dedicated staff of FAA-certified structural, electrical, avionics and Airframe
and Powerplant technicians.

     In addition to domestic and foreign governmental regulations, OEMs,
commercial airlines and other customers require that the Company satisfy certain
requirements relating to the quality of its services. The Coordinated Agency for
Supplier Evaluation ("CASE"), a consortium of United States air carriers,
reviews the operations of the Company on a regular basis for quality and
efficiency. The Company has completed several audits conducted by the FAA and
CASE and has continually met or exceeded the requirements imposed by its
customers and by OEMs.

     The Company's operations are also subject to a variety of worker and
community safety laws. The Occupational Safety and Health Act of 1970 ("OSHA")
mandates general requirements for safe workplaces for all employees. Specific
safety standards have been promulgated for workplaces engaged in the treatment,
disposal or storage of hazardous waste. The Company believes that its operations
are in material compliance with OSHA's health and safety requirements.

ENVIRONMENTAL MATTERS

     The Company's operations, like those of other companies engaged in similar
businesses, are subject to federal, state and local environmental laws and
regulation by government agencies, including the United States Environmental
Protection Agency ("EPA") and the Florida Department of Environmental Protection
("FDEP"). Among other matters, these regulatory authorities impose requirements
that regulate the emission, discharge, generation, management, transportation
and disposition of hazardous materials, pollutants and contaminants, govern
public and private response actions to hazardous or regulated substances which
may be or have been released to the environment, and require the Company to
obtain and maintain licenses and permits in connection with its operations. This
extensive regulatory framework imposes significant compliance burdens and risks
on the Company.

     The Company periodically reviews its reserves for potential environmental
liabilities. Such review includes an evaluation of currently available facts
with respect to each individual site and consideration of factors such as
existing technology, current laws and regulations and the Company's prior
experience in remediation of contaminated sites. As assessments and remediation
efforts progress at individual sites, the Company's environmental reserves and
remediation plans are reviewed and adjusted to reflect the additional legal and
technical information as it becomes available.

     The Company is taking remedial action pursuant to EPA regulations at the
Lake City, Florida facility.


                                       -7-


<PAGE>   8
Environmental testing continues to be performed at this site and the Company is
monitoring the results of such tests to assess the impact and magnitude of the
Company's required remediation efforts. Based upon the most recent cost
estimates provided by the Company's environmental consultants, the Company
believes that the total remaining remediation and compliance costs at this
facility will be approximately $2.4 million. There are, however, other areas on
the property at Lake City that could also require remediation, although the
Company does not believe it is responsible for such areas. In the event
remediation efforts are required in such areas, the Company may be required to
share in the costs of such remediation in order to continue its operations at
Lake City. The Company is unable to estimate the potential amount of such costs
at this time.

     In connection with the sale of Crystek, the Company was required to
perform, at its own expense, an environmental site assessment on the Crystek
Property. The Company is also required to remedy all recognized environmental
conditions identified in the assessment to bring the Crystek Property into
compliance with all applicable Federal, State and local environmental laws. If
the facility is not brought into compliance with such environmental laws by
December 31, 1998, the Crystek Buyer shall have the option of requiring the
Company to repurchase the Crystek Property. The Company has engaged independent
environmental consultants to review the potential environmental liabilities on
the Crystek Property. Such investigation and testing resulted in the
identification of likely environmental remedial actions. Based upon the cost
estimates provided by the consultants, the Company believes that the total
remediation and compliance costs for the Crystek Property will be approximately
$1.0 million.

     Actual costs required to be incurred by the Company in the future for
environmental compliance and remediation may vary from the Company's current
estimates of such costs, primarily because of the inherent uncertainties in
evaluating environmental exposures. These uncertainties include the extent of
remediation based on testing and evaluation not yet completed, the varying costs
and effectiveness of remediation methods and potential changes in environmental
laws, regulations or the interpretations thereof. No assurance can be given that
actual amounts ultimately required to be expended by the Company for
environmental compliance and remediation in the future will not be material.

MATERIALS

     The Company purchases components, parts and equipment from various
suppliers. The Company is not dependent upon any single supplier or group of
suppliers for any of the material it uses in its business and has encountered no
difficulties in purchasing sufficient quantities in the open market.

PATENTS, TRADEMARKS, LICENSES, FRANCHISES AND CONCESSIONS

     The Company holds no material patents, franchises or concessions.

BACKLOG

     Although the Company has in prior years reported backlog in its Annual
Report on Form 10-K and Quarterly Reports on Form 10-Q, management has
determined that the Company is not able to calculate and report with certainty
or reliability the backlog of orders which it believes to be firm. Though the
Company generally enters into written customer contracts, such contracts
generally define the obligations of the parties once an aircraft is delivered
for service but do not usually obligate the customer to deliver for service any
specific number of aircraft or to deliver an aircraft on any specific date. Any
estimate would also be subject to the difficulties of estimating the likelihood
of success of the Company's outstanding bids, the inability to predict services
to be provided in the future on aircraft delivered on a "drop-in" basis and the
fact that anticipated aircraft service dates often extend beyond a fiscal
period. Further estimates of the value of service to be rendered on any
particular aircraft are difficult to make until such time as the aircraft is
actually delivered for service and inspected.

EMPLOYEES

     As of December 31, 1997, the Company has approximately 1,152 full-time
employees. None of the Company's employees are covered by a collective
bargaining agreement. The Company believes that its relations with its employees
are generally good.

</TABLE>


     The Company leases approximately 70,000 sq. ft. of the Dallas, Texas
facility to HTI.

     The Company's aircraft depot located at the Lake City Municipal Airport in
Lake City, Florida spans 120 acres and includes seven maintenance hangars, two
runways, over 1.3 million square feet of ramp space, an FAA-certified control
tower and a fuel farm. The seven clear span steel hangars provide over 650,000
square feet of covered space and can comfortably house up to 18 narrow-bodied
aircraft. There is also covered nose dock space which allows for the sheltered
maintenance of up to four additional aircraft. Six hangars are used for heavy
maintenance and modification and one hangar is dedicated for aircraft striping
and painting. Each hangar has its own technical library, customer representative
offices, tool rooms, storage rooms and a production control center where all of
the paperwork associated with a project's workscope is maintained. Each of the
hangars are in close proximity to one another and to the Company's
administrative offices and hydraulic and sheetmetal shops. The Lake City
facility is operated by the Company under a lease from the City of Lake City
which expires in 2022. Since 1992, the Company has invested more than $9.2
million to renovate and improve the Lake City facility to the point where it is
now capable of accommodating nearly all narrow-bodied and wide-bodied aircraft
in current production.

     The Company's Macon facility consists of five buildings on the East ramp of
the Macon Municipal Airport in Macon, Georgia. With over 140,000 square feet
under roof, the Macon facility can house three DC-8 and three DC-9 aircraft in
its hangar bays. One of its three hangar bays can also accommodate a DC-10 or
A-300 size aircraft.

     The Company believes that its plants and other physical properties are
adequate for its intended operations

ITEM 3.  LEGAL PROCEEDINGS

     On May 10, 1991, an action was filed in the District Court of Dallas
County, Texas, by Lee D. Webster, former Chairman, Chief Executive Officer and
President of Whitehall, against the Company, each of its directors (other than
Mr. Webster) and Cambridge Capital Fund, L.P., alleging, among other things,
that ( i ) the defendants' actions, both individually and in concert,
constituted willful interference with Mr. Webster's employment relationship with
the Company and was the direct cause of Mr. Webster's termination as its
President and Chairman of the Board, and (ii) the defendants' actions forced Mr.
Webster into retirement without providing Mr. Webster with retirement benefits
which Mr. Webster was purportedly promised. On August 17, 1994, the defendants
were granted a partial summary judgment. On October 24, 1994, Mr. Webster filed
a third amended petition and alleged the following causes of action: tortuous
interference with contractual relations against Cambridge Capital Fund, L.P.,
and directors George F. Baker and John J. McAtee; intentional infliction of
emotional distress and breach of oral contracts. The third amended petition
sought compensatory and punitive damages in excess of $35 million.


                                       -9-


<PAGE>   10

On January 12, 1995, the Court entered an abatement on one of the breach of oral
contract claims against the Company and entered a summary judgment in the
defendants' favor on all remaining claims alleged by Mr. Webster. On February
26, 1996, the Court granted a summary judgment in favor of the defendants on Mr.
Webster's remaining claims and entered a take nothing final judgment which
dismissed all of Mr. Webster's claims with prejudice to refiling. On March 26,
1996, Mr. Webster appealed the final judgment to the Dallas, Texas Court of
Appeals. Oral argument was held on November 13, 1997. To date, no decision has
been reached by the court. Management intends to vigorously defend this appeal.

     The Company is also involved in certain legal proceedings in the normal
course of its business. After consultation with counsel, management is of the
opinion that the outcome of the above-mentioned proceedings will not have a
material effect on the financial position or results of operations of the
Company.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     There were no matters submitted for a vote of the Company's stockholders in

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

OPERATING RESULTS

     Consolidated sales totaled $65,791,000 for 1997, a decrease of 6% from
sales of $70,170,000 in 1996. Consolidated sales in 1996 include approximately
$1.9 million of sales in the Ocean Systems segment, which was sold in November
1996. Sales in the Electronics segment decreased by $2,212,000 to $672,000 in
1997. In March of 1997, the Company sold the Electronics segment for $2.7
million, see Item 1B and Note L of the Notes to Consolidated Financial
Statements. Aircraft Maintenance segment sales decreased by $221,000 to
$65,119,000 in 1997, primarily as a result of hangar space that was reserved in
anticipation of the United States Air Force C-130 maintenance contract awarded
in April 1997, which was subsequently canceled at the convenience of the
government in June 1997. The C-130 contract provides for reimbursement by the
United States Air Force of costs incurred during its operation, and the Company
has recorded a claim against the government for these costs. This reduction in
anticipated revenue was partially offset by the acquisition of the Macon,
Georgia facility, which accounted for approximately $12 million of the segment's
sales. Sales are also affected by arrivals of planes later than their scheduled
time.

     Consolidated sales totaled $70,170,000 for 1996, an increase of 25% over
sales of $56,229,000 in 1995. Aircraft Maintenance segment sales increased by
$22,699,000 to $65,340,000 in 1996, primarily as a result of its continued
expansion into the third party commercial aircraft maintenance market. Sales in
the Ocean Systems segment decreased by $8,002,000 to $1,946,000 in 1996.
Revenues in the Ocean Systems segment decreased primarily as a result of
contract completions with no follow-on contract awards. In November 1996, the
Company sold substantially all of the assets of the Ocean Systems segment, see
Item 1B and Note D. Sales in the Electronics segment decreased by $756,000 to
$2,884,000 in 1996.

     Consolidated sales totaled $56,229,000 for 1995, an increase of 75% over
sales of $32,098,000 in 1994. Aircraft Maintenance segment sales increased by
$17,238,000 to $42,641,000 in 1995, primarily as a result of its continued
expansion into the third party commercial aircraft maintenance market. Sales in
the Ocean Systems segment increased by $6,126,000 to $9,948,000 in 1995.
Revenues in the Ocean Systems segment increased primarily as a result of new
product sales in the commercial geophysical market. Sales in the Electronics
segment increased by $767,000 to $3,640,000 in 1995.

     The Company recorded an operating loss of $9,996,000 in 1997 compared to an
operating profit of $5,705,000 in 1996. The Aircraft Maintenance segment
reported an operating loss of $9,764,000 in 1997 compared to an operating profit
of $7,026,000 in 1996 primarily due to the increase in environmental reserves
(see "Environmental Matters" above), an increase in the provision for obsolete
inventory, and an increase in the allowance for doubtful accounts. The allowance
was increased because of disputes with large customers (the ultimate outcome of
which can not be determined at this time) and certain customers in weak
financial condition, including two customers that went into bankruptcy. The
Electronics segment reported an operating loss of $6,000 in 1997 compared to an
operating profit of $557,000 in 1996. The Electronics segment was sold in March
1997. Corporate office general and administrative expenses decreased to $337,000
in 1997 compared to $968,000 in 1996. This decline was the result of lower
insurance and legal expense reserves, as well as a reduction in corporate staff
and staff expenses.

     The Company recorded an operating profit of $5,705,000 in 1996 compared to
an operating profit of $2,875,000 in 1995. The Aircraft Maintenance segment
reported an operating profit of $7,026,000 in 1996 compared to an operating
profit of $3,430,000 in 1995. The improved profitability in the Aircraft
Maintenance segment resulted primarily from the increase in sales. The Company
increased its sales to its three largest customers in 1996 over those same
customers in 1995, mainly because those customers had increased the size of
their fleets. The Ocean Systems segment reported an operating loss of $789,000
in 1996 compared to an operating profit of $419,000 in 1995. The decline in
sales was the primary reason for the 1996 operating loss in the Ocean Systems
segment. The Electronics segment reported an operating profit of $557,000 in
1996 compared to an operating profit of $796,000 in 1995. The decline in sales
was the primary reason for the lower 1996 operating profit in the Electronics
segment. Corporate office general and administrative expenses decreased to
$968,000 in 1996 compared to $2,128,000 in 1995 primarily as a result of
reductions in legal and insurance expenses.

     Other expense, net in 1997 includes the $4,500,000 writedown of the
Company's investment in Hydroscience

Technologies, Inc. (HTI) preferred stock (See Item 1B). Other income in 1996
includes interest earned of $307,000 and investment income of $440,000. Other
income in 1995 includes gains on sales of fixed assets of $650,000 and interest
earned of $671,000. Other income in 1994 includes gains on sales of fixed assets
of $512,000 and interest earned of $791,000.

     The Company recorded an income tax benefit of $3,610,000 in 1997. The
Company recorded net income tax expense of $2,206,000 for 1996 and $889,000 in
1995.

YEAR 2000 ISSUE

     The Year 2000 issue is the result of computer programs being written using
two digits rather than four digits to define the applicable year. Any of the
Company's computer programs that have date-sensitive software may recognize a
date using '00' as the year 1900 rather than the year 2000. If the Company's
systems are unable to recognize or properly treat the year 2000, critical
financial and operational information may be processed incorrectly. The Company
has not yet assessed the year 2000 compliance expense and related potential
effect on the Company's earnings.

LIQUIDITY AND CAPITAL RESOURCES

     During 1997, cash used in operating activities totaled $4,545,000 as
compared to $4,084,000 in 1996 and $1,802,000 in 1995.

     The Company made capital expenditures during 1997 of approximately
$3,739,000 compared to $4,438,000, and $1,668,000 in 1996 and 1995. The majority
of the capital expenditures in all years were made to renovate the Aero facility
in Lake City, Florida. All planned major expansions have been completed as of
December 31, 1997. Including in 1997 capital expenditures was the construction
of a building and the purchase of other items for the C-130 contract and the
completion of the refinishing of various hanger floors. However, the Company
will make capital and other expenditures during 1998 as conditions warrant.

     Cash and cash equivalents decreased from approximately $2,656,000 at
December 31, 1996, to $1,251,000 at December 31, 1997. During 1997, the Company
borrowed an additional $7,163,000 on its line of credit primarily to fund
working capital, the acquisition of the Macon, Georgia facility, and capital
expenditures of $3,739,000. At December 31, 1997, there was approximately
$2,287,000 available under the line of credit.

     The Company believes that, despite the losses generated in 1997 mainly
attributable to the increase in the accounts receivable reserve, the increase in
the environmental reserve, and the writedown of its investment in the HTI
Preferred Stock, its cash balances and line of credit facility are sufficient to
meet its short and long-term capital requirements. The Company intends to
continue to pursue opportunities for the acquisition of aircraft maintenance
facilities, and any future acquisitions may require additional capital. In order
to provide additional funds for the Company's growth strategies and for
operations over the long-term, the Company may incur, from time to time,
additional short and long-term bank indebtedness and may issue, in public or
private transactions, equity and debt securities. The availability and terms of
such securities may depend upon market and other conditions. There can be no
assurances that such potential financing will be available on terms acceptable
to the Company.


FORWARD-LOOKING STATEMENTS

     This Form 10-K includes certain forward-looking statements, including
statements made under Item 7, about anticipated results, liquidity and capital
resources and statements made under Item 1 concerning the anticipated growth of
worldwide air traffic and the expected trend toward greater outsourcing by
commercial air carriers and the US Military. Such forward-looking statements are
based upon known and unknown assumptions, risks, uncertainties, and other
factors which may cause the actual results, performance or achievements of the
Company to be materially different from any future results, performance or
achievements expressed or implied by such forward-looking statements. Factors
that could cause actual results to differ from such expectations include, but
are not limited to, those associated with general economic and business
conditions, aircraft and aerospace industry trends, availability of financing,
and the inability or failure to identify or consummate successful acquisitions
or to assimilate the operations of any acquired businesses with those of the
Company.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Whitehall Corporation and Subsidiaries:

We have audited the accompanying consolidated balance sheets of Whitehall
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1997
and 1996, and the related consolidated statements of operations, shareholders'
equity, and cash flows for the three years in the period ended December 31,
1997. These consolidated financial statements and the schedule referred to below
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements and schedule 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 Whitehall Corporation and
subsidiaries as of December 31, 1997 and 1996, and the results of its operations
and its cash flows for the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index to
financial statements is presented for 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.

                     WHITEHALL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE A -- ACCOUNTING POLICIES AND PRACTICES

Consolidation: The consolidated financial statements of Whitehall Corporation
and subsidiaries (the "Company") include the accounts of all subsidiaries after
elimination of intercompany accounts and transactions.

Use of Estimates: Generally accepted accounting principles require management to
make estimates and assumptions that affect the reported amount of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Reclassifications: Certain reclassifications have been made to 1996 and 1995
amounts to conform with the 1997 presentation.

Long-term Contracts: Revenue on long-term contracts in 1996 and 1995 is
recognized using the percentage of completion or unit of delivery method. On
contracts where the percentage of completion method is applied, revenue is
accrued in the proportion that costs incurred bear to management's estimate of
total contract costs. Any known or anticipated losses are provided for
currently.

Concentration of Credit Risk: Financial instruments which potentially subject
the Company to concentrations of credit risk consist principally of temporary
cash investments and accounts receivable. The Company places its temporary cash
investments with creditworthy financial institutions and, thus, limits the
amount of credit exposure to any one entity. The Company's customer base is
comprised primarily of U.S. airlines and air transport companies.

Cash Equivalents: Cash equivalents consist of highly liquid debt instruments
purchased with an original maturity of three months or less.

Inventories: Inventories are carried at average cost, not in excess of market.

Property, Plant and Equipment: Property, plant and equipment is stated at cost.
Provisions for depreciation and amortization have been computed generally using
the straight-line method over the estimated useful lives of the assets.

Long-Lived Assets: The Company periodically reviews its long-lived assets for
impairment. If this review indicates that the carrying amount of an asset may
not be recovered through future operations or sale, the carrying value of the
asset will be reduced to its fair value. In 1997, the Company recorded an
impairment loss on its investment in preferred stock (see Note D).

Research and Development: Research and development costs are included in
selling, engineering and administrative expenses and amounted to approximately
$41,000 in 1996, and $45,000 in 1995. There were no research and development
costs incurred in 1997.

Federal Income Taxes: The Company accounts for income taxes using an asset and
liability approach for financial accounting and income tax reporting. Deferred
tax liabilities and assets are recognized for the estimated future tax effects
attributable to temporary differences and carryforwards and are adjusted
whenever tax rates or other provisions of income tax statutes change.

The Company and all subsidiaries file a consolidated Federal income tax return.
Deferred federal income taxes have been provided for temporary differences
between tax and financial reporting resulting primarily from depreciation
provisions, allowances and expense accruals.

Earnings (Loss) Per Share: Effective January 1, 1997, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings Per
Share." SFAS No. 128 simplifies the computation of earnings per share (EPS) by
replacing the presentation of primary EPS with a presentation of basic EPS.
Basic EPS is calculated by dividing the income (loss) available to common
shareholders by the weighted average number of common shares outstanding during
the period. Options and other potentially dilutive securities are excluded from
the calculation of basis EPS. Diluted EPS includes options and other potentially
dilutive securities that are excluded from basic EPS to the extent that these
securities are not anti-dilutive. Options were not included in the 1997
computation of diluted EPS because they are anti-dilutive.

The following is a reconciliation between basic and diluted EPS for the years
ended December 31, 1997, 1996, and 1995:

</TABLE>


In accordance with SFAS No. 128, the earnings (loss) per share for all prior
periods have been restated.

Joint Venture Investment: See Note D.

Treasury Shares: During 1991, the Board of Directors authorized the repurchase
of up to 1,000,000 shares of the Company's common stock. An additional
authorization of 500,000 shares was made by the Board of Directors in March
1993. As of December 31, 1997, a total of 1,257,800 shares have been purchased
under these authorizations. The Company did not acquire any treasury stock
during 1995, 1996 or 1997.

Environmental Costs: Environmental expenditures that relate to current
operations are expensed. Remediation costs that relate to existing conditions
caused by past operations are accrued when it is probable that these costs will
be incurred and can be reasonably estimated. Environmental costs are included in
selling, engineering and administrative expenses in the accompanying
consolidated statements of operations.

Other Income (Expense): Other expense for 1997 includes the $4.5 million
writedown of the Company's investment in the preferred stock of Hydroscience
Technologies, Inc. Other income, net in 1996 and 1995 includes interest earned
of $307,000 and $671,000, respectively, and gains on sales of fixed assets of
$11,000 and $650,000, respectively.

Employee Benefits: The Company offers no significant post-employment or
post-retirement benefits.

New Accounting Pronouncements: During 1997, the Financial Accounting Standards
Board (FASB) issued SFAS No. 129, "Disclosure of Information About Capital
Structure," which establishes standards for disclosing certain information about
an entity's capital structure. The statement is effective for years ending after
December 15, 1997, and its adoption did not have any impact on the Company's
financial statements.

During 1997, FASB issued SFAS No. 130, "Reporting Comprehensive Income," which
establishes standards for reporting and display of comprehensive income and its
components (revenues, expenses, gains, and losses) in a company's financial
statements. This statement requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. This Statement does not require a specific format
for that financial statement but requires that an enterprise display an amount
representing total comprehensive income for the period in that financial
statement. This statement requires that an enterprise (a) classify items of
other comprehensive income by their nature in a financial statement and (b)
display the accumulated balance of other comprehensive income separately from
retained earnings and additional paid-in capital in the equity section of a
statement of financial position. SFAS No. 130 is effective for periods beginning
after December 15, 1997.

During 1997, FASB issued SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information." This Statement is effective for financial
statements for periods beginning after December 15, 1997. As the Company is
operating


                                      -23-
<PAGE>   24


in only one segment as of December 31, 1997, and plans to focus solely on the
aircraft maintenance industry, this statement is not expected to have an impact
on the Company's financial statements.

</TABLE>


Accrued sales not billed will be billed on the basis of contract terms and
deliveries. All accrued amounts at December 31, 1997, are expected to be billed
and collected in 1998.



 In April 1997, the Company was awarded the United States Air Force C-130
 maintenance contract, which was subsequently canceled in June 1997 at the
 convenience of the government, based on no fault or issue with the Company. The
 C-130 contract provides for reimbursement by the United States Air Force of
 costs incurred during its operation, and the Company has recorded a $2.8
 million net receivable from the government for these costs, which is the
 Company's best estimate of the amount it will collect for the claim it has
 made. The Company is currently negotiating a termination settlement with the
 government.

NOTE D -- INVESTMENTS

In November 1996, the Company sold substantially all of the assets related to
its Ocean Systems segment to Hydroscience Technologies, Inc. ("HTI") in exchange
for 818,182 shares of HTI Preferred Stock, which carries a liquidation
preference of $5.50 per share. At the Company's election, the HTI Preferred
Stock is convertible after December 31, 1997, into 45% of HTI's Common Stock.
(See Note P for pro forma information related to this transaction.) Although the
purchaser of Ocean


                                      -24-
<PAGE>   25

Systems provided additional capital and new management, the continuing decline
in defense spending and other concerns caused management to reevaluate this
preferred stock in 1997. Management has concluded that the value of its
investment has declined permanently. The entire amount was written off in 1997.

During 1994, the Company obtained 40% ownership of a joint venture involved in
the development of aircraft-related technology for an initial investment of
$1,000. The Company accounts for its investment in the joint venture under the
equity method. In 1994, the Company obtained a promissory note for an advance of
$2,000,000 to the joint venture. The principal balance of the promissory note
accrues interest at a maximum rate of 5% per annum and the principal balance
with accrued interest is due January 5, 1999. The note is secured by certain
assets of the joint venture. During 1997 and 1996, the Company advanced an
additional $815,000 and $75,000 to the joint venture. These advances are
included in accounts receivable.

Summarized balance sheet information for the joint venture as of December 31,
1997 and 1996 is as follows:

NOTE F - LONG-TERM DEBT

The Company entered into a long-term note and a credit facility during 1996 with
a bank. The credit facility consists of a $12,000,000 line of credit agreement
and a $3,000,000 standby letter of credit agreement. Advances under the line of
credit agreement accrue interest at the prime interest rate (8.5% at December
31, 1997). The Company also pays an annual commitment fee of 1/4 of 1 % on the
unused portion of the line of credit. At December 31, 1997, the unused and
available portion of the line of credit was $2,287,000. The line of credit
expires on June 30, 1998. Management is confident that this line will be renewed
or comparable financing can be obtained at June 30, 1998, for at least another
one-year period.

The credit facility is unsecured and contains certain financial covenants
related to working capital, consolidated net income and consolidated tangible
net worth, among other restrictions. The Company was in violation of certain
covenants as of December 31, 1997; however, these covenants have been waived by
the bank.

This debt was incurred to finance the acquisition of certain fixed assets. The
total future debt principal payments are $283,000 in 1998, $263,000 in 1999, and
zero thereafter.

A $1,700,000 standby letter of credit was issued, pursuant to the standby letter
of credit agreement, in order to comply with the annual financial assurances
required by the Florida Department of Environmental Protection and related to
the environmental remediation being performed at the Company's Lake City,
Florida facility (see Note O). The standby letter of credit agreement has an
annual commitment fee of 1% of the amount of the letter of credit.

NOTE G -- SHAREHOLDERS' EQUITY

On January 29, 1997, the Board of Directors declared a 2 for 1 stock split to be
effected in the form of a 100% stock dividend to shareholders of record at the
close of business March 25, 1997. The dividend resulted in $384,000 being
transferred from retained earnings to common stock. This amount represents the
par value of the new stock. All share and per share amounts have been adjusted
to recognize this dividend.

On March 17, 1997, the shareholders approved an amendment to the Company's
Restated Certificate of Incorporation increasing the number of authorized shares
of Common Stock from 5,000,000 shares to 20,000,000 shares.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets and liabilities as of December 31, 1997 and
1996 are as follows:

The Company has established a valuation allowance to offset the deferred tax
assets that have resulted from items that will only be deductible when such
items are actually incurred. The valuation allowance will be maintained until it
is more likely than not that these deferred tax assets will be realized.

NOTE I -- STOCK OPTION PLANS

In May 1992, the stockholders approved the Whitehall Corporation Incentive Stock
Option Plan ("Incentive Plan") and the Whitehall Corporation Non-Employee
Directors Stock Option Plan ("Directors Plan"). The Incentive Plan provides for
the grant of incentive stock options for up to 650,000 shares of Common Stock to
key employees. The Directors Plan provides for the grant of incentive stock
options for up to 130,000 shares of Common Stock to non-employee Directors of
the Company. Under the Plans, the exercise price for stock options will not be
less than the fair market value of the optioned stock at the date of grant.
Stock options expire ten years from the date of grant and generally vest over a
five-year period with one-fifth of the shares becoming exercisable on each of
the five anniversaries of the date of grant. As December 31, 1997, 1996, and
1995 there were 347,100, 218,600, and 196,200 options exercisable, respectively.
The option period under both Plans may not be more than ten years from the date
the option is granted.

The Company accounts for its stock option plans in accordance with Accounting
Principles Board Opinion No. 25, under which no compensation cost has been
recognized for stock option awards. In 1996, the Company adopted SFAS No. 123,
which requires that options be priced using the fair value method, and has
elected the disclosure only alternative. The fair value of each stock option
grant is estimated on the date of grant using the Black-Scholes option pricing
model. Using the fair value method to determine compensation costs, the
Company's pro forma net income and net income per share would be:

be expected in future years.

NOTE J -- SAVINGS PLAN

The Company implemented a voluntary 401(k) savings plan for eligible employees
(as defined by the Plan document) effective September 1, 1992. The Company
contributed $50 per enrolling employee in 1995. The Company contributes 50% of

The Company's contributions vest over a six-year period.

NOTE K - ACQUISITION

In July 1997, the Company acquired an aircraft maintenance company in Macon,
Georgia for approximately $6.7 million in cash and assumed liabilities. This
acquisition involved the purchase of inventories, equipment, and certain
intangible assets. This acquisition was accounted for using the purchase method
of accounting. Accordingly, operations of the acquired business are included in
the accompanying consolidated financial statements for the period subsequent to
the effective date of the acquisition. See Note P for pro forma information for
this acquisition as if it had occurred at the beginning of the fiscal year.

The preliminary estimated fair values assigned to assets acquired and
liabilities assumed is summarized as follows:

NOTE O -- COMMITMENTS AND CONTINGENCIES

Environmental Matters

The Company's operations, like those of other companies engaged in similar
businesses, are subject to extensive and evolving federal, state, and local
environmental laws and regulations. The measurement of environmental liabilities
is based on an evaluation of currently available facts with respect to each
individual site and considers factors such as existing technology, presently
enacted laws and regulations, and prior experience in remediation of
contaminated sites. As assessments and remediation progress at individual sites,
these liabilities are reviewed and adjusted to reflect the additional technical
and legal information as it becomes available. In order to comply with present
federal, state and local provisions which have been enacted or adopted
regulating the discharge of materials into the environment, or otherwise
relating to the protection of the environment, the Company will be required to
fund remediation efforts, which could result in potentially substantial
operating costs and capital expenditures.

The Company is taking remedial action pursuant to Environmental Protection
Agency ("EPA") regulations at the Lake City, Florida facility. Ongoing testing
is being performed and new information is being gathered to continually assess
the impact and magnitude of the required remediation efforts on the Company.
Based upon the most recent cost estimates provided by environmental consultants,
the Company believes that the total remaining remediation and compliance costs
for this facility will be approximately $2.4 million, which has been accrued at
December 31, 1997.

Additionally, there are other areas on the Lake City property that could also
require remediation. The Company believes it 



                                      -31-
<PAGE>   32



is not responsible for these areas; however, it may be required to take part in
the remediation process to continue its operations at that location. No estimate
of any such costs to the Company is available at this time.

In connection with the sale of Crystek (see Note L), Whitehall was required to
perform, at its own expense, an environmental site assessment at the Crystek
facility. The Company is also required to remedy all recognized environmental
conditions identified in the assessment to bring the Crystek facility into
compliance with all applicable Federal, State, and local environmental laws. If
the facility is not brought into compliance with environmental laws by December
31, 1998, the buyer shall have the option of requiring the Company to repurchase
the property. The Company has engaged environmental consultants to review
potential environmental liabilities at the Crystek facility. Such investigation
and testing resulted in the identification of likely environmental remedial
actions. Based upon the cost estimates provided by the consultants, the Company
believes that the total remediation and compliance costs for this facility will
be approximately $1.0 million, which has been accrued at December 31, 1997.

Future information and developments will require the Company to continually
reassess the expected impact of the environmental matters discussed above.
Actual costs to be incurred in future periods may vary from the estimate, given
the inherent uncertainties in evaluating environmental exposures. These
uncertainties included the extent of required remediation based on testing and
evaluation not yet completed and the varying costs and effectiveness of
remediation methods.

To comply with the financial assurances required by the Florida Department of
Environmental Protection (FDEP), the Company requested and a bank issued a
$1,700,000 standby letter of credit in favor of the FDEP. This letter of credit
meets all conditions required by the FDEP.

Legal Matters

On May 10, 1991, an action was filed in the District Court of Dallas County,
Texas, by Lee D. Webster, former Chairman, Chief Executive Officer and President
of Whitehall, against the Company, each of its directors (other than Mr.
Webster) and Cambridge Capital Fund, L.P., alleging, among other things, that 
(i) the defendants' actions, both individually and in concert, constituted
willful interference with Mr. Webster's employment relationship with the Company
and was the direct cause of Mr. Webster's termination as its President and
Chairman of the Board, and (ii) the defendants' actions forced Mr. Webster into
retirement without providing Mr. Webster with retirement benefits which Mr.
Webster was purportedly promised. On August 17, 1994, the defendants were
granted a partial summary judgment. On October 24, 1994, Mr. Webster filed a
third amended petition and alleged the following causes of action: tortuous
interference with contractual relations against Cambridge Capital Fund, L.P.,
and directors George F. Baker and John J. McAtee; intentional infliction of
emotional distress and breach of oral contracts. The third amended petition
sought compensatory and punitive damages in excess of $35 million. On January
12, 1995, the Court entered an abatement on one of the breach of oral contract
claims against the Company and entered a summary judgment in the defendants'
favor on all remaining claims alleged by Mr. Webster. On February 26, 1996, the
Court granted a summary judgment in favor of the defendants on Mr. Webster's
remaining claims and entered a take nothing final judgment which dismissed all
of Mr. Webster's claims with prejudice to refiling. On March 26, 1996, Mr.
Webster appealed the final judgment to the Dallas, Texas Court of Appeals. Oral
argument was held on November 13, 1997. To date, no decision has been reached by
the court. Management intends to vigorously defend this appeal.

The Company is also involved in certain legal proceedings in the normal course
of its business. After consultation with counsel, management is of the opinion
that the outcome of the above-mentioned proceedings will not have a material
effect on the financial position or results of operations of the Company.

The pro forma financial information does not purport to represent what the
results of operations of the Company would have actually been if the
aforementioned transactions had occurred on January 1, 1996, nor does it project
the results of operations for any future periods.

 NOTE Q -- RELATED PARTY TRANSACTIONS

 As of December 31, 1997, two former officers of the Company were indebted to
 the Company in the aggregate amount of approximately $363,000. This amount is
 classified as accounts receivable and is fully reserved.
 These receivables will be written off in 1998.

 NOTE R -- SUBSEQUENT EVENT

 On March 24, 1998, the Company entered into a definitive agreement with
 Aviation Sales Company (AVS). Under the terms of the agreement, the Company
 will exchange its common stock for common stock of AVS. This transaction is
 expected to be accounted for as a pooling of interests.

          failure by the Seller to perform any contract, commitment or

                                    Article 3

                            Acquisition Consideration

          Section 3.1 Acquisition Consideration. (a) In consideration of the
sale, conveyance, assignment and transfer of the Assets by the Seller to the
Purchaser and in reliance on the representations and warranties made herein by
the Seller and the Stockholders, the Purchaser agrees on the Closing Date (i) to
assume the Assumed Liabilities in accordance with Section 2.2, (ii) to pay, by
wire transfer or other immediately available funds, One Million Two Hundred
Thousand Dollars ($1,200,000); (iii) to pay, in immediately available funds, an
additional inventory payment (the "Inventory Prepayment") in the amount of Three
Hundred Thousand Dollars ($300,000) (which Inventory Prepayment shall be
governed by the terms and conditions set forth below in Section 3.1(b)) and
(iv) an amount allocated to the Seller out of the amounts pre-paid by the Seller
with respect to rent and other pre-paid expenses (including utility payments and
other deposits) under the Facility Lease for the month in which the Closing
shall occur (the "Closing Month"), and which allocation to the Seller shall be
made on the basis of the number of days left in the Closing Month as of the
Closing Date. The consideration set forth in clauses (i), (ii), (iii) and (iv)
above, collectively, shall be hereafter referred to as the "Acquisition
Consideration").

          (b) The Inventory Prepayment shall be deemed to be a credit against
purchases by the Purchaser of the Seller's inventory on the Closing Date and/or
subsequently thereafter. As such, the Purchaser shall from time to time elect to
purchase inventory items at a purchase price of the then fair market value, and
such purchase price shall be deducted from the Inventory Prepayment. Upon the
Inventory Prepayment credit balance being reduced to zero, the Purchaser shall
have the right to purchase inventory from time to time at a purchase price equal
the then fair market value, which purchase price shall be paid in cash, within
thirty (30) days from the date of such purchase. For purposes of this Agreement,
"fair market value" shall be determined, with respect to purchases of inventory
made at Closing, by mutual agreement of the parties, and, with respect to
purchases made subsequent to the Closing, the lesser of the Seller's list price
of each item of inventory or the amount that the Purchaser could then purchase
such item of inventory on the open market. At Closing, the Seller shall deliver
to the Purchaser the list price of all inventory items, which list shall be set
forth as Schedule 3.1(b) attached hereto. All inventory of the Seller located at
the Facility shall remain at the Facility after the Closing Date. Thereafter,
any items of inventory may be sold by the Seller to a third party, provided
that, prior to the consummation of any such sale, the Seller shall send written
notice to the Purchaser of the Seller's desire to sell such inventory and the
purchase price offered by a third party, and thereupon, the Purchaser shall have
the right, exercisable within five (5) business days from receipt of the
Seller's notice, to purchase any and all of such items of inventory at the same
purchase price for such items as set forth in the Seller's notice.

          Section 4.1 Delivery of Documents. (i) At the Closing, the Seller and

of Sale").

                                    Article 5

mutually agreed upon by the parties (the "Closing Date"), the parties hereto
will take all actions necessary to (A) effect the Acquisition and (B) satisfy
the document delivery requirements on which the obligations of the parties to

actions collectively being the "Closing"). The Closing shall be effective as of

in each jurisdiction where the character of the properties and assets owned,
leased or operated by it or the nature of the business conducted by it makes

or in the aggregate, a material adverse effect on the business, financial
condition or results of operations of the Seller.

Agreement and to consummate the transactions contemplated hereby. The execution,
delivery and performance of this Agreement by the Seller and the consummation of
the transactions contemplated hereby have been duly authorized by the board of
directors of the Seller and by all other all requisite corporate action on the
part of the Seller, including the obtaining of the requisite vote or consent of
the Seller's stockholders. This Agreement has been duly executed and delivered
by the Seller and is a valid and binding obligation of the Seller, enforceable
against the Seller in accordance with its terms.

Instruments. The execution and delivery by the Seller of this Agreement do not,

          Filing"), in each case on the part of or with respect to the Seller,
          except for those Government Consents and Governmental Filings with

          Licenses held by the Seller and identified on Schedule 6.4; and

               (3) require, on the part of the Seller, any consent by or

          Section 6.4) or otherwise, except as and to the extent specified on
          Schedule 6.4;

               (4) assuming that all Government Consents, Government Filings,
          Contract Consents and Contract Notices described in clauses (2) and

received by the Seller since January 1, 1992 relating in whole or in part to the
existence of Hazardous Substances at any Owned Property or Leased Real Estate or
any real property previously owned or operated by the Seller or the compliance
of the Seller with respect to any Environmental Law.

          Section 6.20 Insurance. Schedule 6.20 sets forth all policies or
binders of fire, liability, workmen's compensation, vehicular or other insurance
held by or on behalf of the Seller




                                      -17-

with respect to the Business (specifying the insurer, the policy number or
covering note number with respect to binders, and describing each pending claim
thereunder of more than $5,000, setting forth the aggregate amounts paid out
under each such policy through the date of this Agreement and the aggregate
limit of any of the insurer's liability thereunder). Such policies and binders
are in full force and effect and insure against risks and liabilities customary
for companies of similar size, financial condition and engaged in the business
in which the Seller is engaged. The Seller is not in default with respect to
payment of any premium or any provision contained in any such policy or binder
and has not failed to give any notice or present any claim under any such policy
or binder in due and timely fashion. Except for claims set forth on Schedule
6.20, there are no outstanding unpaid claims under any such policy or binder,
and the Seller has not been advised of any defense to coverage in connection
with any claim to coverage asserted or noticed by the Seller under or in
connection with any of its extant insurance policies. The Seller has not
received any written notice from or on behalf of any insurance carrier issuing
policies or binders relating to or covering the Seller that there will be a
cancellation or non-renewal of existing policies or binders, or that alteration
of any equipment or assets or any improvements to real estate occupied by or
leased to or by the Seller, purchase of additional equipment or assets, or
material modification of any of the methods of doing business, will be required.
The Seller has no knowledge of any inaccuracy in any application for such
policies or binders, any failure to pay premiums when due or any similar state
of facts which might form the basis for termination of any such insurance.

          Section 6.21 Brokers or Finders. No agent, broker, investment banker,
financial advisor or other person or entity is or will be entitled, by reason of
any agreement, act or statement by the Seller, to any financial advisory,
broker's, finder's or similar fee or commission in connection with any of the
transactions contemplated by this Agreement.

          Section 6.22 Full Disclosure. No statement herein or in the Schedules
hereto or in any certificate delivered pursuant to the requirements of this
Agreement by or on behalf of the Seller contains or will contain any untrue
statement of a material fact concerning the Seller or any of its Affiliates, or
omits or will omit to state a material fact necessary in order to make the
statements made herein or therein concerning the Seller or any of its
Affiliates, in light of the circumstances under which they were made, not
misleading.

hereunder and thereunder. The Purchaser is duly authorized, qualified or
licensed to do business as a foreign corporation, and is in good standing, in
all other jurisdictions in which its right, title or interest in or to any
asset, or the conduct of its business, requires such authorization,
qualification or licensing, except where the failure to so qualify or to be in
good standing would not have a material adverse effect on the ability of the
Purchaser to perform its obligations hereunder.

          Section 7.2 Authorization and Validity of Agreement. The execution,
delivery and performance of this Agreement and the other agreements and
instruments contemplated by this Agreement to be executed in connection with the
Acquisition by the Purchaser and the consummation by the Purchaser of the
transactions contemplated hereby and thereby have been duly authorized by its
board of directors. No other corporate action is necessary for the
authorization, execution, delivery and performance by the Purchaser of this
Agreement and such other agreements and instruments and the consummation by the
Purchaser of the transactions contemplated hereby or thereby. This Agreement has
been duly executed and delivered by the Purchaser and constitutes the legal,
valid and binding obligation of the Purchaser, enforceable in accordance with
its terms.

          Section 7.3 No Approvals or Notices Required: No Conflict with
Instruments to which the Purchaser is a Party. The execution, delivery and
performance of this Agreement and the other agreements and instruments in
connection with the Acquisition by the Purchaser and the consummation by it of
the transactions contemplated thereby (i) will not violate (with or without the
giving of notice or the lapse of time or both), or require any consent,
approval, filing or notice under, any provision of any law, rule or regulation,
court order, judgment or decree applicable to the Purchaser, except for such
violations the occurrence of which, and such consents, approvals, filings or
notices the failure of which to obtain or make, would not in the aggregate
reasonably be expected to have a material adverse effect on the Purchaser's
ability to perform its obligations hereunder or thereunder, and (ii) will not
conflict with, or result in the breach or termination of any provision of, or
constitute a default under, or result in the acceleration of the performance of
the obligations of the Purchaser under, the charter or bylaws of the Purchaser,
or any indenture, mortgage, deed of trust, lease, licensing agreement, contract,
instrument or other agreement to which the Purchaser is a party or by which the
Purchaser or any of its assets or properties is bound, except for such
conflicts, breaches, terminations, defaults, accelerations or liens which would
not in the aggregate reasonably be expected to have a material adverse effect on
the Purchaser's ability to perform its obligations hereunder or thereunder.

                                    Article 8

                                    Covenants

       reasonable access during normal business hours to the representatives,
       officers, Employees and contractors of the Seller involved in the

       may reasonably request; provided that the Purchaser shall not take any
       action to supervise the Seller's Employees or otherwise operate the
       Business. The Seller shall have the right to have its representatives
       present at any discussions between the Purchaser and any of the persons
       specified in this Section, and the Purchaser agrees to schedule such
       discussions through the Seller.

              Section 8.2   Conduct of the Business Pending the Closing Date.
       The Seller agrees that, except as required or contemplated by this
       Agreement or otherwise consented to or approved in writing by the
       Purchaser, during the period commencing on the date hereof and ending on
       the Closing Date, it will:

              (a)    operate and maintain the Business in all material respects
       only in the usual, regular and ordinary manner consistent with past

       maintenance, use its best efforts to preserve the present business
       organization of the Business intact, keep available the services of the
       present Employees (subject to the Purchaser's rights to direct the
       Seller to terminate any Employee pursuant to Section 8.10) and preserve
       its present relationships with all persons having business dealings with
       the Business;

              (b)    maintain its books, accounts and records relating to the
       Business in the usual, regular and ordinary manner, on a basis

       conduct of the Business and perform all of its material obligations
       relating to the Business;

              (c)    not (i) modify or change in any material respect any of
       the Assets or dispose of any material Asset except for (A) the sale of
       inventory in the ordinary course of business, consistent with past
       practice, and (B) any Assets that in the ordinary course of business are
       replaced with substantially similar Assets, (ii) enter into any
       Contract, commitment or other agreement that would be material to the
       operation of the Business or use of the Assets or, except as expressly
       contemplated by this Agreement or expressly contemplated by or required
       pursuant to their respective terms, modify or change in any material
       respect any obligation under any such Contract, commitment or agreement,
       (iii) modify or change in any material respect any obligation under any
       License, (iv) modify or change in any material respect the manner in

              (d)    not (i) permit or allow any of the Assets to become
       subject to any Liens, (ii) waive any material claims or rights relating
       to the Business, (iii) grant any increase in the compensation or
       benefits of any of the Seller's Employees (including any such increase
       pursuant





                                      -20-
<PAGE>   22
       to any bonus, pension, profit-sharing or other plan or commitment),
       except (A) for reasonable increases in the ordinary course of business
       that are consistent with past practice or (B) for reasonable payments in
       normal sales compensation plans, including bonuses, consistent with past
       practice or (iv) agree, whether in writing or otherwise, to do any of

              (e)    not take any action that would result in the
       representations with respect to the Seller as contained in this
       Agreement not being true as of the Closing Date if the representations
       were given for the period from the date hereof through the Closing Date;

              Section 8.3   Cooperation by the Purchaser. The Purchaser hereby
       covenants and agrees to respond to any and all of the Seller's requests
       for consents required pursuant to this Article as promptly as reasonably
       practicable, provided that the Purchaser shall have been provided with
       all information it may reasonably request or that is otherwise
       reasonably necessary to evaluate such request for consent.

              Section 8.4   Risk of Loss. On or prior to the Closing, risk of
       loss, damage or destruction to the Assets and risk of taking of the
       Facility or any of the Assets or any portion of the Business by eminent
       domain shall be borne by the Seller. In the event of any such loss,
       damage or destruction not repaired or replaced by the Seller, the
       Purchaser on or prior to the Closing shall have the option of (a)
       causing the Seller to assign and transfer to the Purchaser all such
       proceeds receivable under any insurance policy for any such loss, damage
       or destruction or the receivable from any such taking by eminent domain,
       as the case may be, (b) reducing the Purchase Price by the amount of the
       reasonable good faith estimate of the cost of repair or replacement or
       the reasonable good faith estimate of the amount of proceeds from such
       taking by eminent domain, as the case may be, or (c) terminating this
       Agreement, without liability to either party. The parties further
       acknowledge and agree that the risk of loss, damage or destruction of
       the inventory items to remain at the Facility as Retained Assets, and
       risk of taking by eminent domain with respect to such items, shall be
       borne by the Seller until such time as the inventory items are purchased
       by the Purchaser.

       Section 8.5   Further Actions.

              (a)    Subject to the terms and conditions hereof, the Seller and
       the Purchaser agree to use their commercially reasonable efforts to
       take, or cause to be taken, all actions and to do, or cause to be done,
       all things necessary, proper or advisable to consummate and make
       effective the transactions contemplated by this Agreement, and to
       confirm that such transactions have been accomplished, including,
       without limitation, using all commercially reasonable efforts (without
       commencement of litigation): (i) to obtain prior to the Closing all
       Licenses and consents to the transfer of any Licenses that are
       transferable by the Seller; (ii) to effect all necessary registrations
       and filings; and (iii) to furnish to each other such information and

                                      -21-
<PAGE>   23
              (b)    All Government Consents and Contract Consents in respect
       of the Seller as are required in connection with the consummation of the
       transactions contemplated hereby shall have been obtained by the Seller
       and shall be in full force and effect, all Governmental Filings and
       Contract Notices in respect of the Seller or the Business as are
       required in connection with the consummation of such transactions shall
       have been made by the Seller, and all Licenses of the Seller that are
       required to be transferred in connection with the consummation of such
       transactions shall have been transferred by the Seller.

              Section 8.6   Work-In-Progress. (a) WIP relating to the Business
       as of the Closing Date shall be undertaken by the Purchaser and shall be
       performed until completion after the Closing Date. Upon such completion,
       the Seller acknowledges that the Purchaser shall have the sole
       responsibility to bill any finished products and services to the
       applicable customer. The effective time (the "WIP Effective Time") of
       transfer of all WIP shall be 12:01 a.m. on the Closing Date in order to
       calculate the allocation of revenues received from customers with respect
       to completed WIP. WIP to be performed on a time and materials basis shall
       be billed out and revenues received allocated on a pro rata basis based
       upon the WIP Effective Time. Revenue collected from WIP performed on a
       flat rate basis, shall be allocated on the basis of the formula set forth
       in the following sentence. The Seller's proportional share of revenues
       received by the Purchaser with respect to WIP items performed at a flat
       rate shall be equal to the fraction that is obtained by dividing (i) the
       Seller's actual labor and material expense (each calculated at normal
       customer billing rates) by (ii) the sum of (A) the Seller's actual labor
       and material expense (each calculated at normal customer billing rates)
       plus (B) the Purchaser's actual labor and material expense (each
       calculated at normal customer billing rates). Upon the Purchaser's
       receipt of payment in respect of such completed WIP, the Purchaser shall,
       within ten (10) business days, deliver to the Seller its allocable share
       of such payment, in accordance with the foregoing formulas.
       Notwithstanding the foregoing, nothing contained in this Section 8.7
       shall be deemed to impose any liability on the Purchaser in the event
       that any completed WIP becomes or remains uncollectible, in whole or in
       part, and accordingly, the Purchaser only shall be obligated to use its
       commercially reasonable efforts (which shall not include the commencement
       of litigation) to collect from customers payment with respect to
       completed WIP and to remit to the Seller the payments due to the Seller
       in accordance with the terms of this Section.

              (b)    The Seller hereby acknowledges and agrees that the Seller
       shall remain liable for any warranty claims or other claims for breach
       of contract, negligence, personal injury, property or any other claims,
       suits, actions, litigation, judgments, costs (including, without
       limitation, reasonable attorneys' fees and disbursements), losses and
       other damages and liabilities, relating to, arising out of or in
       connection with, WIP (collectively, the "WIP Claims") to the extent that
       any of such WIP Claims were incurred or accrued prior to the Closing or
       otherwise arose out of, or are attributable to work performed or
       conditions existing prior to Closing. All such WIP Claims asserted
       against the Purchaser shall be handled in accordance with procedures
       for indemnification under Section 10.1.

              Section 8.7   Non-Competition; Non-Solicitation. Neither the
       Seller nor any of the Stockholders shall enter into direct or indirect
       competition (whether as an owner, partner, member,





                                      -22-
<PAGE>   24
       officer, director, employee, consultant or in any other capacity) with
       the Business or relating to, or connected with, the Assets, or the
       business activities to be conducted by the Purchaser at the Facility on
       and after the Closing Date (provided, however, the Seller shall be
       permitted to perform maintenance on airplanes and parts owned by the
       Seller, so long as the Seller does not engage in any third party
       maintenance activities); and (ii) neither the Seller nor any of the
       Stockholders shall solicit any of the Employees retained by the
       Purchaser, any person or entity that is a customer of the Seller with
       respect to the Business as of the date hereof or on the Closing Date, or
       any person or entity that is as of the Closing Date, or becomes after
       the Closing Date, a customer of the Purchaser with respect to the
       Business. The restrictions in clause (i) of the preceding sentence, as
       to James M. Zantop only, shall terminate one (1) year from the date of
       this Agreement. The Seller acknowledges and agrees that the scope of the
       Business is nationwide, and accordingly, the scope of the foregoing
       non-competition provision shall extend throughout the United States. The
       parties hereby expressly agree that the scope of the non-competition
       restriction is necessary and reasonable to assure that the Purchaser is
       permitted to enjoy the benefits of this Agreement as contemplated by the
       parties hereunder. The parties further agree that the Seller's present
       third-party airplane maintenance business at Willow Run Airport for
       Spirit Airlines, Inc. and USAJet, Inc. is not competitive with the
       Business.

              Section 8.8   License to Use Seller's Name. In consideration for
       the Purchaser's entering into this Agreement, the Seller hereby grants
       and licenses to the Purchaser the non-exclusive right and license, on
       royalty-free basis, to use the name "Zantop," individually or in
       connection with other words or phrases, with respect to assumed or
       "doing-business-as" names used in connection with the Business. The
       foregoing license shall terminate on the one year anniversary of the
       Closing Date; provided, however, that if at such termination date there
       exists any unsatisfied indemnification claims, then the Purchaser shall,
       in addition, to any and all other rights and remedies that the Purchaser
       may have in law or in equity, be permitted to continue to possess and
       use the license until all such indemnification claims are satisfied by
       the Seller or the Stockholders, as the case may be.

              Section 8.9   Maintenance of Existing Accounting System.  The
       Seller and the Purchaser hereby agree that from the date hereof and
       extending through a maximum of 120 days from the Closing Date, the
       Seller shall continue to maintain the existing accounting system with
       respect to the Business, and in connection therewith, the Seller shall
       also provide the Purchaser with access to the Seller's central computer
       system to the extent of such accounting system. In consideration for the
       foregoing services, the Purchaser shall pay to the Seller $4,500 per
       month (the "Monthly Accounting Fee") for any month that the Purchaser
       desires to have the Seller provide such services, plus the cost of any
       required programming changes (provided that any such proposed changes
       and the estimated cost thereof have been pre-approved in writing by the
       Purchaser) at the Seller's standard billing rate of $50 per hour;
       provided, that the Purchaser shall not acquire any interest in the
       Seller's operating software by reason of such payments; and provided,
       further that the Purchaser may terminate the Seller's services at any
       time within the 120 day period, so long as the Purchaser pays to the
       Seller a pro rata portion of the Monthly Accounting Fee, based on the
       number of days left in the month in which services are being provided at
       the time of termination.

       Section 8.10  Retention of Employees. The Seller and the Purchaser hereby
expressly agree that the Purchaser shall have no obligation whatsoever to retain
or hire the existing Employees of the Seller as of the Closing Date.
Furthermore, the Seller agrees that the Seller shall, at the instruction of the
Purchaser, terminate any Employee's employment prior to or on the Closing Date,
and, in connection therewith, the Purchaser shall assume no liability arising
from such terminations, and Seller shall indemnify and hold the Purchaser
harmless in accordance with Section 10.1 for any claim or liability arising out
of the terminations.

                                   ARTICLE 9

executive order promulgated or enacted by any United States federal, provincial
or state governmental authority which restrains, enjoins or otherwise prohibits
the transactions contemplated hereby shall be in effect; provided, that before
any determination is made to the effect that this condition has not been
satisfied, the Seller and the Purchaser shall each use commercially reasonable
efforts and take such other actions as may be reasonably necessary, at its own
expense, to have such order or injunction lifted or dismissed.

representations and warranties had been made on and as of the Closing Date,
with only such exceptions as would not in the aggregate reasonably be expected

results of operations of the Business; provide, however, that to the extent
that any such representation or warranty refers to financial or other
information that





                                      -24-
<PAGE>   26

              (c)    Significant Events and Incidental Losses. After the date
       of this Agreement, no event, occurrence or other matter has occurred

              Section 9.4   Conditions Precedent to the Obligations of the

pay certain administrative expenses in connection with the Bonds; and

         WHEREAS, the City has determined that the construction of the Project
in the manner and for the purpose set forth herein will result in both short

enhance the ability of the City and the Issuer to provide for future
development of industrial sites contiguous to the Airport; and

         WHEREAS, in consideration of the foregoing public benefits and as
security for the payment of the Bonds, the City will enter into a contract with
the Issuer, dated the date hereof (the "Contract"), whereby, in consideration
of the Issuer's agreement to issue the Bonds, the City agrees to pay certain
amounts equal to principal, premium (if any) and interest on the Bonds as they
come due in the event that moneys therefor are unavailable under this
Agreement, and further, to levy an annual tax within the limits prescribed by

necessary to produce funds sufficient to make the above payments to the Issuer
pursuant to the Contract; and

provided, however, no Determination of Taxability shall occur under

                                REPRESENTATIONS


         Section 2.1. Representations by the Issuer. The Issuer makes the
following representations as the basis for the undertakings on its part herein
contained:

         (a) Organization and Authority. The Issuer is a public body corporate
     and politic and an instrumentality of the City of Macon and the County of
     Bibb, created and validly existing pursuant to the Constitution and laws of
     the State, including particularly the provisions of the Act. The Issuer has
     all requisite power and authority under the Act to (i) issue the Bonds,
     (ii) use the proceeds thereof to acquire, construct and install the
     Project, (iii) own, lease and dispose of the Project, and (iv) enter into
     and perform its obligations under, this Agreement and the Indenture. The
     Issuer has sufficient title to the Leased Land by means of a leasehold
     interest from the City to perform and fulfill its obligations hereunder.

         (b) Pending Litigation. There are no actions, suits, proceedings,
     inquiries or investigations pending, or to the knowledge of the Issuer
     threatened, against or affecting the Issuer in any court or before any
     governmental authority or arbitration board or tribunal, which involve the
     possibility of materially and adversely affecting the transactions
     contemplated by this Agreement, the Contract or the Indenture or which
     would in any way adversely affect the validity or enforceability of the
     Bonds, the Indenture, the Contract, this Agreement or any agreement or
     instrument to which the Issuer is a party and which is used or contemplated
     for use in the consummation of the transactions contemplated hereby or
     thereby.

         (c) Security for the Bonds. As security for the Bonds, the Issuer has,
     as of the date hereof, entered into the Contract with the City, pursuant to
     which the City, in consideration of the Issuer's agreement to issue the
     Bonds, has agreed to make certain payments equal to the amount of
     principal, premium (if any) and interest falling due on the Bonds should
     funds payable under this Agreement be insufficient to make said payments.
     Pursuant to the Contract, the City has further agreed to levy an annual tax
     within the limits prescribed by law on all taxable property located in the
     City at such rate or rates as may be necessary to produce funds sufficient
     to make the above payments to the Issuer pursuant to the Contract. The
     Issuer's rights under this Agreement are not being pledged under the terms
     of the Indenture as security for the Bonds but are pledged by the 


                                      -10-
<PAGE>   16


     Issuer to the City under the Contract as security for the City.

         (d) Issue, Sale, and Other Transactions Are Legal and Authorized. The
     issuance and sale of the Bonds and the execution and delivery by the Issuer
     of this Agreement, the Contract and the Indenture, and the compliance by
     the Issuer with all of the provisions of each thereof and of the Bonds (i)
     are within the purposes, powers and authority of the Issuer, (ii) have been
     done in full compliance with the provisions of the Act, are legal and will
     not conflict with or constitute on the part of the Issuer a violation of or
     a breach of or default under, or result in the creation of any lien, charge
     or encumbrance upon any property of the Issuer (other than as contemplated
     by this Agreement and the Indenture) under the provisions of any charter
     instrument, by-law, indenture, mortgage, deed of trust, note agreement or
     other agreement or instrument to which the Issuer is a party or by which
     the Issuer is bound, or any license, judgment, decree, law, statute, order,
     rule or regulation of any court or governmental agency or body having
     jurisdiction over the Issuer or any of its activities or properties, and
     (iii) have been duly authorized by all necessary corporate action on the
     part of the Issuer.

         (e) Governmental Consents. Neither the nature of the Issuer nor any of
     its activities or properties, nor any relationship between the Issuer and
     any other person, nor any circumstance in connection with the offer, issue,
     sale or delivery of any of the Bonds is such as to require the consent,
     approval or authorization of, or the filing, registration or qualification
     with, any governmental authority on the part of the Issuer in connection
     with the execution, delivery and performance of this Agreement, the
     Contract and the Indenture or the offer, issue, sale or delivery of the
     Bonds, other than those already obtained, including specifically (i) the
     public approval of the issuance of the Bonds and compliance with the
     information reporting requirements contained in Section 147(f) and Section
     149(e), respectively, of the Code, and (ii) the validation of the Bonds by
     the Superior Court of the County.

         (f) No Defaults. No event has occurred and no condition exists with
     respect to the Issuer which would constitute an "event of default" as
     defined in this Agreement, the Contract or the Indenture or which, with the
     lapse of time or with the giving of notice or both, would become an "event
     of default" under this Agreement, the Contract or the Indenture. The Issuer
     is not in default under the Act or under any charter, instrument, by-law or
     other agreement or instrument to which it is a party or by which it is
     bound.

<PAGE>   17


         (g) No Prior Pledge. This Agreement has not been pledged or
     hypothecated in any manner or for any purpose by the Issuer as security for
     the payment of the Bonds. The Issuer has agreed with the City in the
     Contract that it will apply rentals hereunder to the payment of the Bonds
     before calling on the City for any payments necessary to pay the Bonds.

         (h) Disclosure. Neither the representations of the Issuer contained in
     this Agreement, the Contract and the Indenture nor any written statement
     relating to the Issuer furnished to the original purchasers of the Bonds by
     or on behalf of the Issuer in connection with the transactions contemplated
     hereby, contains any untrue statement of a material fact or omits to state
     a material fact necessary in order to make the statements contained herein
     and therein not misleading.

         (i) Nature and Location of Project. The financing of the Project is in
     furtherance of the public purposes intended to be served by the Act. The
     Project will be located within Bibb County, Georgia.

         (j) Official Action. By resolution duly adopted on November 3, 1992,
     the Issuer took "official action" (within the meaning of Section
     1.103-8(a)(5) of the Income Tax Regulations) providing for the acquisition,
     construction and installation of the Project and the financing of the cost
     of the Project, in whole or in part, through the issuance of the Bonds.

         (k) Limited Obligations. Notwithstanding anything herein contained to
     the contrary, any obligation the Issuer may hereby incur for the payment of
     money shall not constitute an indebtedness of the State or of any political
     subdivision thereof within the meaning of any state constitutional
     provision or statutory limitation and shall not give rise to a pecuniary
     liability of the State or a political subdivision thereof, or constitute a
     charge against the general credit or taxing power of said State or a
     political subdivision thereof, but shall be limited obligations of the
     Issuer payable solely from (i) revenues derived from the sale of the Bonds,
     and (ii) amounts on deposit from time to time in the Project Fund and the
     Bond Fund, including payments made into the Bond Fund pursuant to the
     Contract, subject to the provisions of this Agreement and the Indenture
     permitting the application thereof for the purposes and on the terms and
     conditions set forth herein and therein.

<PAGE>   18


         (l) Use of Proceeds. Not less than 95% of the net proceeds of the sale
     of the Bonds have been used to acquire land or property of a character
     subject to the allowance for depreciation under Section 167 of the Code and
     such costs representing proceeds so used are properly chargeable to the
     capital account of the Issuer for federal income tax purposes or would be
     so chargeable either with a proper election by the Issuer or but for a
     proper election by the Issuer to deduct the costs.

         (m) Inducement. The issuance of the Bonds by the Issuer and the use of
     the proceeds to enable the Company to acquire, construct and install the
     Project have induced the Company to locate the Project in the County,
     which will directly result in an increase in employment opportunities in
     the City of Macon, Georgia, for approximately one hundred forty (140)
     additional persons.

         (n) Operation of Project. The Company intends to operate the Project
     from the Completion Date to the expiration or sooner termination of this
     Agreement as provided herein as a "project" within the meaning of the Act,
     and as an "exempt facility" as described in Section 2.2(n) hereof.

         (o) Commencement of Construction. The acquisition, construction and
     installation of the Project commenced after November 3, 1992, and no
     obligation relating to the acquisition, construction or installation of the
     Project was paid or incurred prior to such date.

         (p) Composite Issues. There are no other obligations heretofore issued
     or to be issued by or on behalf of any state, territory or possession of
     the United States, or political subdivision of any of the foregoing, or of
     the District of Columbia, for the benefit of the Issuer or any "Related
     Person" (as that term is defined in Section 147(a)(2) of the Code), which
     constitute "private activity bonds" within the meaning of Section 141 of
     the Code and which (i) were or are to be sold at substantially the same
     time as the Bonds, (ii) were or are to be sold at substantially the same
     interest rate as the interest rate of the Bonds, (iii) were or are to be
     sold pursuant to a common plan of marketing as the marketing plan for the
     Bonds, and (iv) are payable directly or indirectly by the Issuer or from
     the source from which the Bonds are payable.

         (q) I.R.S. Form 8038 Information. The information furnished by the
     Issuer and used by the Issuer in connection with preparing I.R.S. Form
     8038, "Information Return for Tax-Exempt Private Activity Bond Issues,"
     which has been filed by or on behalf of the Issuer with the Internal
     Revenue Service

     Center in Philadelphia, Pennsylvania, pursuant to Section 149(e) of the
     Code, was true and complete as of the date of the filing thereof.

         (r) Exempt Facility. Section 103(a) of the Code provides that, except
     as provided in Section 103(b), gross income does not include interest on
     any State or local bond. Section 103(b) provides that Section 103(a) does
     not apply to any private activity bond which is not a "qualified bond"
     within the meaning of Section 141 of the Code. Section 141 defines a
     private activity bond as any bond issued as part of an issue where more
     than 10 percent of the proceeds of that issue are (1) to be used for any
     private business use and the payment of principal or interest on more than
     10 percent of the proceeds of the issue is (under the terms of the issue or
     any underlying arrangement) directly or indirectly secured by any interest
     in property to be used for a private business use or payments in respect of
     such property, or (2) to be derived from payments (whether or not to the
     issuer) in respect of property, or borrowed money, used or to be used for a
     private business use.

         As more than 10 percent of the proceeds of the Bonds will be used in a
     private business use and the payment of the principal of and the interest
     on more than 10 percent of the proceeds of the Bonds will be derived from
     payments in respect of property to be used for a private business use, the
     Bonds are "private activity bonds" under Section 141 of the Code. Section
     141(d)(1)(A) defines the term "qualified bond" as any private activity bond
     if such bond is an exempt facility bond, and qualified bonds are included
     in the interest exclusion of Section 103(a).

         Section 142(a)(1) defines "exempt facility bonds" as any bond issued as
     part of an issue 95 percent or more of the net proceeds of which are to be
     used to provide facilities for an airport, so the Bonds will be "exempt
     facility bonds" under Section 142(a)(1) of the Code. Further, in
     compliance with the requirements of Section 142(b) of the Code, all the
     property to be financed by the net proceeds of the issue is to be owned by
     the City. The City has, pursuant to the Lease, leased the Leased Land to
     the Issuer, and the Issuer has hereunder subleased the Leased Land to the
     Company for a term of twenty-five years. Pursuant to this Agreement and in
     compliance with Section 142(b)(1)(B) of the Code, the Company has made in
     Section 8.12 hereof an irrevocable election, binding on the Company and all
     successors in interest under this Agreement, not to claim depreciation or
     an investment tax credit with respect to the Project or the Leased Land.
     The twenty-five-year term of this Agreement (including any renewal options
     contained herein), for the purposes of Section 168(i)(3) of the Code, is
     not more than 80 percent of





                                      -14-

<PAGE>   20

     the reasonably expected economic life of the Project (as determined under
     Section 147(b) of the Code). Also in compliance with Section 142(b)(1)(B),
     the Company has no option to purchase the Project or to renew or extend the
     Lease Term except at fair market value (as of the time the option is
     exercised).

         (s) Limitation on Maturity. The weighted average maturity of the Bonds
     does not exceed the weighted average estimated economic life of the
     components comprising the Project by more than 20%, determined pursuant to
     Section 147(b) of the Code.

         (t) Restrictions on Financings and Operation of Certain Facilities. At
     no time will:

             (i) any portion of the net proceeds of the sale of the Bonds be
         used to provide any airplane, skybox, or other private luxury box, any
         health club facility, any facility primarily used for gambling, or any
         store the principal business of which is the sale of alcoholic
         beverages for consumption off premises; or

             (ii) any portion of the proceeds of the sale of the Bonds be used
         (directly or indirectly) for the acquisition of land (or an interest
         therein) to be used for farming purposes, or 25% or more of the net
         proceeds of the sale of the Bonds be used (directly or indirectly) for
         the acquisition of land other than land to be used for farming
         purposes; or

             (iii) any portion of the net proceeds of the sale of the Bonds be
         used for the acquisition of any property or any interest therein, other
         than land or an interest in land as provided in the preceding
         subparagraph, unless the first use of such property is pursuant to such
         acquisition; provided, however, that this limitation shall not apply
         with respect to any building (and the equipment therefor) if
         "Rehabilitation Expenditures" (hereinafter defined) with respect to
         such building equal or exceed fifteen percent of the portion of the
         cost of acquiring such building (and equipment) financed with proceeds
         of the Bonds; or, in the case of structures other than a building, if
         Rehabilitation Expenditures with respect to such structure equal or
         exceed one hundred percent of the portion of the cost of acquiring such
         structure financed with the proceeds of the Bonds. The term
         "Rehabilitation Expenditures" means any amount properly chargeable to
         the capital account of the Company or a successor to the Company or by
         the seller under a sales contract with the Company for the property
         acquired in connection with the rehabilitation

             


                                     -15-

         of such property, or in the case of property constituting equipment, in
         connection with the replacement of such equipment with equipment having
         substantially the same function, excluding, however, (A) expenditures
         described in Section 48(g)(2)(B) of the Code and (B) amounts incurred
         after the date two years after the later of the date of acquisition of
         the property in question or the date of issuance and delivery of the
         Bonds.


         (u) Reasonable Expectations. Based on current facts, estimates and
     circumstances, it is expected that:

             (i) the acquisition, construction and installation of the Project
         and the expenditure of all Bond proceeds will be completed by May 1,
         1994,

             (ii) work on the Project (which has commenced) will proceed with
         due diligence to completion,

             (iii) the net proceeds of the sale of the Bonds are needed for the
         purpose of paying all or a part of the cost of the acquisition,
         construction and installation of the Project, and

             (iv) the Project will not be sold or disposed of, in whole or in
         part, prior to payment in full of the Bonds.


         (v) Substantial Binding Obligation. The Company reasonably expects to
     enter into various contracts providing for the acquisition, construction
     and installation of the Project within six months of the issuance of the
     Bonds, and the amounts required to be paid under said contracts are
     expected to exceed $100,000 or 2 1/2%, whichever is less, of the estimated
     total cost of the Project.

         (w) Federal Guaranty Prohibition. The Company shall take no action and
     shall not permit or suffer any action to be taken if the result of the same
     would be to cause the Bonds to be "federally guaranteed" within the
     meaning of section 149(b) of the Code.

         (x) Limitation on Issuance Costs. From the proceeds of the Bonds
     received from the initial purchasers thereof on the date of issuance and
     delivery of the Bonds, and investment earnings thereon, an amount not in
     excess of two percent (2%) of the face amount of the Bonds shall be used to
     pay for, or provide for the payment of, Issuance Costs.

         Section 2.2. Representations by the Company. The Company makes the
following representations as the basis for the undertakings on its part herein
contained:

         (a) Corporate Organization and Power. The Company (i) is a corporation
     duly organized, validly existing and in good standing under the laws of the
     State of Michigan and is qualified to do business and is in good standing
     under the laws of the State, and (ii) has all requisite power and authority
     and all necessary licenses and permits to own and operate its properties
     and to carry on its business as now being conducted and as presently
     proposed to be conducted.

         (b) Pending Litigation. There are no proceedings pending, or to the
     knowledge of the Company threatened, against or affecting the Company in
     any court or before any governmental authority or arbitration board or
     tribunal which involve the possibility of materially and adversely
     affecting the properties, profits or condition (financial or otherwise) of
     the Company, or the ability of the Company to perform its obligations under
     this Agreement. The only litigation pending, or to the knowledge of the
     Company, threatened, against or affecting the Company is fully described in
     a schedule which has been furnished to the Issuer by the Company. The
     Company is not in default with respect to an order of any court,
     governmental authority or arbitration board or tribunal.


         (c) Agreements Are Legal and Authorized. The execution and delivery by
     the Company of this Agreement and the compliance by the Company with all of
     the provisions hereof and thereof (i) are within the power of the Company,
     (ii) will not conflict with or result in any breach of any of the
     provisions of, or constitute a default under, or result in the creation of
     any lien, charge or encumbrance (other than Permitted Encumbrances) upon
     any property of the Company under the provisions of, any agreement, charter
     document, by-law or other instrument to which the Company is a party or by
     which it may be bound, or any license, judgment, decree, law, statute,
     order, rule or regulation of any court or governmental agency or body
     having jurisdiction over the Company or any of its activities or
     properties, and (iii) have been duly authorized by all necessary corporate
     action on the part of the Company.

         (d) Governmental Consent. Neither the Company nor any of its business
     or properties, nor any relationship between the Company and any other
     person, nor any circumstances in connection with the execution, delivery
     and performance by the Company of this Agreement or the offer, issue, sale
     or delivery by the Issuer of the Bonds, is such as to require the consent,
     approval or authorization of, or the filing,



                                      -17-

<PAGE>   23

     registration or qualification with, any governmental authority on the part
     of the Company other than those already obtained.

         (e) No Defaults. No event has occurred and no condition exists with
     respect to the Company that would constitute an "event of default" under
     this Agreement or the Indenture, or which, with the lapse of time or with
     the giving of notice or both, would become an "event of default" under this
     Agreement or the Indenture. The Company is not in violation in any material
     respect of any agreement, charter document, by-law or other instrument to
     which it is a party or by which it may be bound.

         (f) Compliance with Law. The Company is not in violation of any laws,
     ordinances, governmental rules or regulations to which it is subject and
     has not failed to obtain any licenses, permits, franchises or other
     governmental authorizations necessary to the ownership of its properties or
     to the conduct of its business, which violation or failure to obtain might
     materially and adversely affect the properties, business, prospects,
     profits or condition (financial or otherwise) of the Company.

         (g) Restrictions on the Company. The Company is not a party to any
     contract or agreement that restricts the right or ability of the Company to
     enter into this Agreement.

         (h) Disclosure. Neither the representations of the Company contained in
     this Agreement, nor any written statement relating to the Company furnished
     by or on behalf of the Company to the Issuer or to the original purchasers
     of the Bonds in connection with the transactions contemplated hereby or
     thereby, contains any untrue statement of a material fact or omits to state
     a material fact necessary to make the statements contained herein or
     therein not misleading. There is no fact that the Company has not disclosed
     to the Issuer and to the City in writing that materially and adversely
     affects or in the future may (so far as the Company can now reasonably
     foresee) materially and adversely affect the acquisition, construction,
     installation, ownership or operation of the Project, or the properties,
     business, prospects, profits or condition (financial or otherwise) of the
     Company, or the ability of the Company to perform its obligations under
     this Agreement or any documents or transactions contemplated hereby.

         (i) Inducement. The issuance of the Bonds by the Issuer and the use of
     the proceeds to enable the Company to acquire, construct and install the
     Project have induced the Company to locate the Project in the County, which
     will directly result in an increase in employment opportunities in




                                      -18-
<PAGE>   24

     the City of Macon, Georgia, for approximately one hundred forty (140)
     additional persons.

         (j) Operation of Project. The Company intends to operate the Project
     from the Completion Date to the expiration or sooner termination of this
     Agreement as provided herein as a "project" within the meaning of the Act,
     and as an "exempt facility" as described in Section 2.2(n) hereof.

         (k) Commencement of Construction. The acquisition, construction and
     installation of the Project commenced after November 3, 1992, and no
     obligation relating to the acquisition, construction or installation of
     the Project was paid or incurred prior to such date.

         (1) Composite Issues. There are no other obligations heretofore issued
     or to be issued by or on behalf of any state, territory or possession of
     the United States, or political subdivision of any of the foregoing, or of
     the District of Columbia, for the benefit of the Company or any "Related
     Person" (as that term is defined in Section 147(a)(2) of the Code), which
     constitute "private activity bonds" within the meaning of Section 141 of
     the Code and which (i) were or are to be sold at substantially the same
     time as the Bonds, (ii) were or are to be sold at substantially the same
     interest rate as the interest rate of the Bonds, (iii) were or are to be
     sold pursuant to a common plan of marketing as the marketing plan for the
     Bonds, and (iv) are payable directly or indirectly by the Company or from
     the source from which the Bonds are payable.

         (m) I.R.S. Form 8038 Information. The information furnished by the
     Company and used by the Issuer in connection with preparing I.R.S. Form
     8038, "Information Return for Tax-Exempt Private Activity Bond Issues,"
     which has been filed by or on behalf of the Issuer with the Internal
     Revenue Service Center in Philadelphia, Pennsylvania, pursuant to Section
     149(e) of the Code, was true and complete as of the date of the filing
     thereof.

         (n) Exempt Facility. Section 103(a) of the Code provides that, except
     as provided in Section 103(b), gross income does not include interest on
     any State or local bond. Section 103(b) provides that Section 103(a) does
     not apply to any private activity bond which is not a "qualified bond"
     within the meaning of Section 141 of the Code. Section 141 defines a
     private activity bond as any bond issued as part of an issue where more
     than 10 percent of the proceeds of that issue are (1) to be used for any
     private business use and the payment of principal or interest on more than
     10 percent of the proceeds of the issue is (under the terms of the issue or

                                           



                                      -19-

<PAGE>   25
     any underlying arrangement) directly or indirectly secured by any interest
     in Property to be used for a private business use or payments in respect of
     such property, or (2) to be derived from payments (whether or not to the
     issuer) in respect of property, or borrowed money, used or to be used for a
     private business use.

         As more than 10 percent of the proceeds of the Bonds will be used in a
     private business use and the payment of the principal of and the interest
     on more than 10 percent of the proceeds of the Bonds will be derived from
     payments in respect of property to be used for a private business use, the
     Bonds are "private activity bonds" under Section 141 of the Code. Section
     141(d)(1)(A) defines the term "qualified bond" as any private activity bond
     if such bond is an exempt facility bond, and qualified bonds are included
     in the interest exclusion of Section 103(a).

         Section 142(a)(1) defines "exempt facility bonds" as any bond issued as
     part of an issue 95 percent or more of the net proceeds of which are to be
     used to provide facilities for an airport, so the Bonds will be "exempt
     facility bonds" under Section 142(a)(1) of the Code. Further, in compliance
     with the requirements of Section 142(b) of the Code, all the property to be
     financed by the net proceeds of the issue is to be owned by the City. The
     City has, pursuant to the Lease, leased the Leased Land to the Issuer, and
     the Issuer has hereunder subleased the Leased Land to the Company for a
     term of twenty-five years. Pursuant to this Agreement and in compliance
     with Section 142(b)(1)(B) of the Code, the Company has made in Section 8.12
     hereof an irrevocable election, binding on the Company and all successors
     in interest under this Agreement, not to claim depreciation or an
     investment credit with respect to the Project or the Leased Land. The
     twenty-five-year term of this Agreement (including the seven-year renewal
     option contained herein), for the purposes of Section 168(i)(3) of the
     Code, is not more than 80 percent of the reasonably expected economic life
     of the Project (as determined under Section 147(b) of the Code). Also in
     compliance with Section 142(b)(1)(B), the Company has no option to purchase
     the Project or to renew or extend the Lease Term except at fair market
     value (as of the time the option is exercised).

         (o) Limitation on Maturity. The weighted average maturity of the Bonds
     does not exceed the weighted average estimated economic life of the
     components comprising the Project by more than 20%, determined pursuant to
     Section 147(b) of the Code.

         (p) Restrictions on Financing and Operation of Certain Facilities. At
     no time will:



                                      -20-

<PAGE>   26


             (i) any portion of the net proceeds of the sale of the
         Bonds be used to provide any airplane, skybox, or other private luxury
         box, any health club facility, any facility primarily used for
         gambling, or any store the principal business of which is the sale of
         alcoholic beverages for consumption off premises; or 
        
             (ii) any portion of the proceeds of the sale of the Bonds be used
         (directly or indirectly) for the acquisition of land (or an interest
         therein) to be used for farming purposes, or 25% or more of the net
         proceeds of the sale of the Bonds be used (directly or indirectly) for
         the acquisition of land other than land to be used for farming
         purposes; or

             (iii) any portion of the net proceeds of the sale of the Bonds be
         used for the acquisition of any property or any interest therein, other
         than land or an interest in land as provided in the preceding
         subparagraph, unless the first use of such property is pursuant to such
         acquisition; provided, however, that this limitation shall not apply
         with respect to any building (and the equipment therefor) if
         "Rehabilitation Expenditures" (hereinafter defined) with respect to
         such building equal or exceed fifteen percent of the portion of the
         cost of acquiring such building (and equipment) financed with proceeds
         of the Bonds; or, in the case of structures other than a building, if
         Rehabilitation Expenditures with respect to such structure equal or
         exceed one hundred percent of the portion of the cost of acquiring such
         structure financed with the proceeds of the Bonds. The term
         "Rehabilitation Expenditures" means any amount properly chargeable to
         the capital account of the Company or a successor to the Company or by
         the seller under a sales contract with the Company for the property
         acquired in connection with the rehabilitation of such property, or in
         the case of property constituting equipment, in connection with the
         replacement of such equipment with equipment having substantially the
         same function, excluding, however, (A) expenditures described in
         Section 48(g)(2)(B) of the Code and (B) amounts incurred after the date
         two years after the later of the date of acquisition of the property in
         question or the date of issuance and delivery of the Bonds.
                 
         (q) Reasonable Expectations. Based on current facts, estimates and
     circumstances, it is expected that:



                                      -21-

<PAGE>   27


             (i) the acquisition, construction and installation of the Project
         and the expenditure of all Bond proceeds will be completed by May 1,
         1994.

             (ii) work on the Project (which has commenced) will proceed with
         due diligence to completion,

             (iii) the net proceeds of the sale of the Bonds are needed for the
         purpose of paying all or a part of the cost of the acquisition,
         construction and installation of the Project, and

             (iv) the Project will not be sold or disposed of, in whole or in
         part, prior to payment in full of the Bonds.

         (r) Substantial Binding Obligation. The Company reasonably expects to
     enter into various contracts providing for the acquisition, construction
     and installation of the Project within six months of the issuance of the
     Bonds, and the amounts required to be paid under said contracts are
     expected to exceed $100,000 or 2 1/2%, whichever is less, of the estimated
     total cost of the Project.

         (s) Federal Guaranty Prohibition. The Company shall take no action and
     shall not permit or suffer any action to be taken if the result of the same
     would be to cause the Bonds to be "federally guaranteed" within the
     meaning of section 149(b) of the Code.

         (t) Limitation on Issuance Costs. From the proceeds of the Bonds
     received from the initial purchasers thereof on the date of issuance and
     delivery of the Bonds, and investment earnings thereon, an amount not in
     excess of two percent (2%) of the face amount of the Bonds shall be used to
     pay for, or provide for the payment of, Issuance Costs.

                      LEASING CLAUSES AND TITLE TO PROJECT


         Section 3.1. Lease of the Project. The Issuer hereby leases to the
Company, and the Company hereby leases from the Issuer, the Project at the rent
set forth in Section 5.2 and in accordance with the provisions hereof.

         Section 3.2. Lease Term and Renewal Options. This Agreement shall
become effective upon its execution and delivery, and the leasehold interest
created hereby shall then begin, and, subject to the other provisions hereof,
shall expire at midnight, May 1, 2018. The Company shall also have the option to
renew the Lease Term for one seven-year period at fair market value at the time
that the option is exercised.

         It is the specific understanding of the parties hereto that, pursuant
to the terms of the Lease, upon either (i) prepayment of all of the rental
amounts due under Section 5.2 hereof and all other amounts due and payable to
the bondholders and/or to the Trustee with respect to the payment of the Bonds,
including reasonable counsel fees, or (ii) the Company's election to exercise
its option to renew the Lease Term following the expiration thereof on May 1,
2018, the Issuer shall assign its interest in this Agreement to the City and
shall notify the Company and the City of such payment and shall advise the
parties that the City has become the Lessor under this Agreement. Upon such
assignment and notice, the Issuer's position as Lessor in this Agreement shall
terminate and the City shall immediately become the Lessor of the Project
hereunder, and upon such event, the City shall immediately and automatically
assume all of the rights, duties, powers and responsibilities of the Issuer as
to this Agreement. At the expiration of this Agreement at midnight on May 1,
2018, should the Company elect not to exercise its renewal option, or at the end
of the last option to renew exercised by the Company pursuant to this Section,
or upon repossession pursuant to Section 9.2 hereof, the Project shall be
returned to the City in good condition and repair.

         Section 3.3. Title to Project. The Issuer hereby represents and
warrants that the City holds fee simple title in and to the Leased Land subject
only to the Lease and this Agreement. The Project shall be the property of the
City and subject to the terms of the Lease and this Agreement.

         Section 3.4. Quiet Enjoyment. The Issuer warrants and agrees that it
will defend the Company in the quiet enjoyment and peaceable possession of the
Project, free from all claims of all persons claiming by, through or under the
Issuer throughout the Lease Term, so long as the Company shall perform the
agreements to



                                      -23-


<PAGE>   29




be performed by it hereunder, or so long as the period for remedying any failure
in such performance shall not have expired. The City has, pursuant to the terms
of the Lease, agreed that it will defend the Issuer in the quiet enjoyment and
peaceable possession of the Project, free from all claims of all persons
claiming by, through or under the City throughout the Lease Term, so long as the
Issuer shall perform the agreements to be performed by it under the Lease, or so
long as the period for remedying any failure in such performance shall not have
expired.

                                   ARTICLE IV.

                           COMMENCEMENT AND COMPLETION
                      OF THE PROJECT; ISSUANCE OF THE BONDS

          Section 4.1. Agreement to Acquire and Construct the Project. Not
later than the delivery hereof the Issuer will have leased the Leased Land from
the City and the Issuer agrees that:

          (a) it will cause the Project to be constructed on the Leased Land,
     wholly within the boundary lines thereof. It will acquire, construct and
     install other facilities necessary for the completion and commencement of
     operation of the Project. The aforesaid acquisition, construction and
     installation shall be substantially in accordance with the Plans and
     Specifications, or, to the extent permitted by Section 8.10(c), and
     amendments thereto as may be agreed to by the parties hereto.

          (b) it will cause to be acquired and installed in the Project or on
     the Leased Land, the Leased Equipment, to consist of machinery, equipment
     and related property described in the list attached hereto as Exhibit "B"
     and such other items of machinery, equipment and related property as in the
     Company's judgment may be necessary for the operation of the Project. The
     Leased Equipment shall be the property of the City and subject to the terms
     of the Lease and this Agreement.

          The Issuer, to the maximum extent permitted by law, hereby makes,
constitutes and appoints the Company as its true, lawful and exclusive agent for
the acquisition, construction and installation of the Project, and the Company
hereby accepts such agency to act and do all things on behalf of the Issuer, to
perform all acts of the Issuer hereinbefore provided in this Section 4.1. and to
bring any actions or proceedings against any person which the Issuer might bring
with respect thereto as the Company shall deem proper. The Issuer hereby
ratifies and confirms all actions of, and assumes and adopts all contracts
entered into by, the Company with respect to the Project prior to the date
hereof. This appointment of the Company to act as agent and all authority hereby
conferred or granted is conferred and granted irrevocably, until all activities
in connection with the acquisition, construction and installation of the Project
shall have been completed, and shall not be terminated prior thereto by act of
the Issuer or of the Company.

          The Company agrees to construct and install the Project with all
reasonable dispatch and to use its best efforts to cause said construction and
installation to be completed as soon as practicable, delays incident to strikes,
riots, acts of God or the




                                      -25-

public enemy beyond the reasonable control of the Company only excepted, but if
said construction and installation is not completed within the time herein
contemplated there shall be no resulting liability on the part of the Company
and no diminution in or postponement or abatement of the rents required in
Section 5.2 to be paid by the Company.

          Section 4.2. Agreement to Issue Bonds; Application of Proceeds. In
order to provide funds for the payment of the cost of the acquisition,
construction and installation of the Project, the Issuer agrees that as soon as
possible it will authorize, validate, sell and cause to be delivered to the
initial purchaser or purchasers thereof, the Bonds, bearing interest and
maturing as set forth in Article II of the Indenture, at a price to be approved
by the Company. Upon the issuance and delivery of the Bonds, all accrued
interest (if any) derived from the sale of the Bonds shall be paid into the Bond
Fund. The balance of the proceeds of the sale of the Bonds shall be deposited
into the Project Fund.

          Section 4.3. Disbursements from the Project Fund. The Issuer will in
the Indenture authorize and direct the Trustee to use the moneys in the Project
Fund for the following purposes but, subject to the provisions of Section 4.8,
for no other purposes:

          (a) payment of interest prior to the Completion Date, payment to the
     Company and to the Issuer, as the case may be, of such amounts, if any, as
     shall be necessary to reimburse either of them in full for all advances and
     payments made by either of them prior to or after the delivery of the Bonds
     for expenditures in connection with clearing the Leased Land, site
     improvement, the preparation of the Plans and Specifications (including any
     preliminary study or planning of the Project or any aspect thereof), the
     construction of the Project, the acquisition and installation of the Leased
     Equipment and the acquisition, construction and installation necessary to
     provide utility services or other facilities including trackage to connect
     the Project with public transportation facilities, and all real or personal
     properties deemed necessary in connection with the Project, or any one or
     more of said expenditures (including architectural, engineering and
     supervisory services) with respect to any of the foregoing; provided,
     however, that in no event shall moneys be disbursed from the Project Fund
     to reimburse the City for any advances or payments made by the City in
     connection with site preparation on the Leased Land undertaken pursuant to
     any obligation of the City to make said site improvements.

          (b) payment of, or reimbursement of the Company and the Issuer for,
     Issuance Costs, but in any event not more than 



                                      -26-
<PAGE>   32



     two percent (2.0%) of the face amount of the Bonds shall be used for such
     purposes as provided by the Code;

          (c) payment of, or reimbursement of the Company for, labor, services,
     material, supplies and/or equipment used or furnished in site improvement
     and in the construction of the Project, all as provided in the Plans and
     Specifications, payment for the cost of the acquisition and installation of
     the Leased Equipment, payment for the cost of acquisition, construction and
     installation of utility services or other facilities including trackage to
     connect the Project with public transportation facilities, and all real and
     personal properties deemed necessary in connection with the Project and
     payment for the miscellaneous expenses incidental to any of the foregoing;

          (d) payment of, or reimbursement of the Company for, the fees, if any,
     for architectural, engineering and supervisory services with respect to the
     Project;

          (e) payment of, or reimbursement of the Company, subject to the
     limitation on the use of the proceeds of the Bonds for the payment of,
     Issuance Costs;

          (f) payment of, or reimbursement of the Company and the Issuer for,
     any other legal and valid costs and expenses relating to the Project,
     subject to the limitation on the use of the proceeds of the Bonds for the
     payment of Issuance Costs; and

          (g) all moneys remaining in the Project Fund (including moneys earned
     on investments made pursuant to the provisions of Section 4.8) after the
     Completion Date and payment in full of the cost of the acquisition,
     construction and installation of the Project, and after payment of all
     other items provided for in the preceding subsections of this Section then
     due and payable, shall be used to reimburse the City for any payments it
     may have made pursuant to the Contract, and thereafter, at the direction of
     the Company shall be (i) used to acquire, construct and install additions,
     extensions and improvements to the Project in accordance with amended Plans
     and Specifications therefor duly filed with the Issuer subject to Section
     8.10(c), (ii) deposited into the Bond Fund and used by the Trustee to the
     maximum extent practicable consistent with making partial redemptions in
     amounts of not less than $5,000 or integral multiples thereof, for the
     redemption of Bonds at the earliest date permitted by the indenture or the
     purchase of Bonds for the purpose of cancellation at any time prior to the
     earliest date permitted by the Indenture for the redemption of Bonds, or
     (iii) deposited into the Bond Fund and used by the Trustee to pay interest
     on the Bonds, or (iv) a combination of (i), (ii) and/or (iii) as is
     provided in 



                                      -27-
<PAGE>   33



     such direction, provided that amounts approved by the Authorized Company
     Representative shall be retained by the Trustee in the Project Fund for
     payment of costs not then due and payable. Any balance remaining of such
     retained moneys after full payment of all such Project costs shall be used
     by the Trustee as directed by the Company in the manner specified in
     clauses (i), (ii), (iii) or (iv) of this subsection. Amounts directed by
     the Company to be used by the Trustee to redeem Bonds or to purchase Bonds
     for the purpose of cancellation shall not, pending such use, be invested at
     a yield which exceeds the yield on the Bonds, unless the Trustee shall
     receive an opinion of nationally recognized bond counsel acceptable to the
     Trustee stating that such use would not affect the exclusion of the
     interest on the Bonds from gross income for federal income tax purposes.
     Amounts in excess of the aggregate of 3% of the net proceeds of the sale of
     the Bonds shall not be directed by the Company to be used for the purposes
     described in clauses (i), (ii), (iii) or (iv) without providing the Trustee
     with an opinion of a firm of nationally recognized bond counsel acceptable
     to the Trustee stating that such use will not impair the exclusion of the
     interest on the Bonds from gross income for federal income tax purposes. In
     the event the yield must be so restricted, the Trustee shall be entitled to
     rely upon advice from such legal and accounting experts as may be
     reasonably required, and the costs of such advice shall be borne by the
     Company.

          The payments specified in subsections (a) through (g) of this Section
(other than payment of interest on the Bonds accruing prior to the Completion
Date) shall be made by the Trustee only upon receipt of the following;

          (1) a written requisition for such payment signed by the Authorized
     Company Representative and, subject to the indemnification provisions of
     Section 8.3 hereof, the Authorized Issuer Representative;

          (2) a certificate by the person signing such requisition certifying;

               (i) that an obligation in the stated amount has been incurred in
          connection with the issuance of the Bonds or the acquisition,
          construction and installation of the Project;

               (ii) that such obligation is a proper charge against the Project
          Fund and has not been the basis of any previous withdrawal from the
          Project Fund, and specifying the purpose and circumstances of such
          obligation in reasonable detail and the name and address of the person
          to whom such obligation is owed, 


                                      -28-
<PAGE>   34



          accompanied by a bill or statement of account for such obligation;

               (iii) that (A) he has no notice of any vendors', materialmen's,
          mechanics', suppliers', or other similar liens or right to liens,
          chattel mortgages or conditional sales contracts, or other contracts
          or obligations which should be satisfied or discharged before payment
          of such obligation is made, or (B) such requisition is for the purpose
          of obtaining funds to be used to satisfy or discharge a lien or
          contract of the type described in (A) above;

               (iv) that such requisition contains no request for payment on
          account of any portion of such obligation which the Company is, as of
          the date of such requisition, entitled to retain under any retained
          percentage agreements;

               (v) that such requisition contains no request for payment on
          account of any obligation paid or incurred prior to November 3, 1992;
          and

          (3) with respect to any such requisition for payment for labor,
     services, material, supplies and/or equipment, an additional certificate,
     signed by the Authorized Company Representative and Authorized Issuer
     Representative, certifying that insofar as such obligation was incurred for
     labor, services, material, supplies and/or equipment in connection with the
     acquisition, construction and installation of the Project, such labor
     and/or services were actually performed in a satisfactory manner and such
     material, supplies and/or equipment were actually used in or about the
     construction or delivered at the site of the Project for that purpose and
     that the item of equipment with respect to which any payment is requested
     constitutes Leased Equipment. Such requisition and certification shall be
     in substantially the form attached hereto as Exhibit "C" and by this
     reference thereto made a part hereof. The Trustee may require additional
     certifications as in its reasonable judgment may be necessary. The
     Authorized Issuer Representative may rely conclusively on any certification
     furnished it by Dennis & Dennis, Inc. with respect to any of the foregoing.

          In making any such payment from the Project Fund the Trustee may rely
on any such requisitions and any such certificates delivered to it pursuant to
this Section and the Trustee shall be relieved of all liability with respect to
making such payments in accordance with any such requisitions and such
supporting certificate or certificates without inspection of the Project or any
other investigation. Disbursements from the Project 


                                      -29-

Fund for deposit in the Bond Fund to pay interest on the Bonds accruing during
the Construction Period may be made by the Trustee at the proper times without
the necessity of receiving any such written requisition or supporting
certificate pertaining thereto.

          The Issuer and the Company agree for the benefit of each other and for
the benefit of the Trustee and the holders of the Bonds that the proceeds of the
Bonds will not be used in any manner which would result in the loss of the
exemption from federal income taxation of the interest on the Bonds.

          Section 4.4. Obligation to Furnish Documents to Trustee. The Company
agrees to furnish to the Trustee the documents referred to in Section 4.3 that
are required by the Trustee to effect payments out of the Project Fund, and to
cause such requisitions and certificates to be directed by the Authorized
Company Representative to the Trustee as may be necessary to effect such
payments. Such obligation of the Company is subject to any provisions hereof or
of the Indenture requiring additional documentation with respect to payments and
shall not extend beyond the moneys in the Project Fund available for payment
under the terms of the Indenture.

          Section 4.5. Establishment of Completion Date. The Completion Date
shall be evidenced to the Trustee by a certificate signed by the Authorized
Company Representative stating that, except for amounts retained by the Trustee
for Project costs not then due and payable as provided in Section 4.3(g),

          (a) the acquisition, construction and installation of the Project have
     been completed substantially in accordance with the plans and
     specifications therefor and all labor, services, materials, supplies and/or
     equipment used in such acquisition, construction and installation have been
     paid for,

          (b) all other facilities necessary in connection with the Project have
     been acquired, constructed and installed substantially in accordance with
     the Plans and Specifications therefor and all costs and expenses incurred
     in connection therewith have been paid,

          (c) the Project and all other facilities in connection therewith have
     been acquired, constructed and installed to his satisfaction and are
     suitable and sufficient for the efficient operation of the Project for its
     intended purposes, and

          (d) a certificate of occupancy, if required, and any other permissions
     required of governmental authorities for the occupancy of the Project have
     been obtained.


                                      -30-
<PAGE>   36



Notwithstanding the foregoing, such certificate by the Authorized Company
Representative shall state that it is given without prejudice to any rights
against third parties which exist on the date of such certificate or which may
subsequently come into being and shall be in substantially the form attached
hereto as Exhibit "D" and by this reference thereto made a part hereof. The
Company agrees to furnish a copy of such certificate to the Issuer at the same
time such document is furnished to the Trustee.

          Section 4.6. Company Required to Pay Project Costs If Project Fund
Insufficient. If the moneys in the Project Fund available for payment of the
cost of the Project should not be sufficient to pay the cost thereof in full,
the Company agrees to complete the Project and to pay all that portion of the
cost of the Project as may be in excess of the moneys available therefor in the
Project Fund. The Issuer does not make any warranty, either express or implied,
that the moneys which will be paid into the Project Fund and which, under the
provisions of this Agreement, will be available for payment of the cost of the
Project will be sufficient to pay all costs which will be incurred in that
connection. The Company agrees that if after exhaustion of the moneys in the
Project Fund the Company should pay any portion of the cost of the Project
pursuant to the provisions of this Section, it shall not be entitled to any
reimbursement therefor from the Issuer or from the Trustee or from the holders
or owners of any of the Bonds, nor shall it be entitled to any diminution in or
postponement of the payments required to be made hereunder.

          Section 4.7. Issuer to Pursue Remedies Against Suppliers, Contractors
and Their Sureties. At the direction and sole cost of the Company (to the extent
that such cost is not payable and actually paid from the Project Fund), the
Issuer will promptly proceed, either separately or in conjunction with others,
to exhaust the remedies of the Issuer against any defaulting supplier,
contractor or subcontractor and against any surety therefor, for the performance
of any contract made in connection with the Project. If the Company shall so
notify the Issuer, the Company may, in its own name or in the name of the
Issuer, prosecute or defend any action or proceeding or take any other action
involving any such supplier, contractor, subcontractor or surety which the
Company deems reasonably necessary, and in such event the Issuer agrees to
cooperate fully with the Company and to take all necessary actions or
proceedings. In addition, the Issuer recognizes that it may be entitled to a
refund of certain sales, use or other taxes levied and paid on goods and
merchandise which are used in the construction of the Project and which become
an integral part thereof. The Issuer agrees that it will, at the request and
expense of the Company, take all necessary action to obtain any such refund to
which it is entitled. Any moneys recovered by way of damages, refunds,
adjustments or otherwise in connection with the foregoing prior to the
Completion Date shall 




                                      -31-
<PAGE>   37



be paid into the Project Fund and after the Completion Date shall be used as
authorized by Section 4.3(g).

          Section 4.8. Investment of Bond Fund and Project Fund Moneys
Permitted. Any moneys held in the Bond Fund or the Project Fund shall be
invested or reinvested by the Trustee upon the oral request and direction of the
Company, promptly confirmed in writing, in Permitted Investments as defined in
the Indenture, to the extent permitted by the laws of the State. Such
investments shall be made upon direction of the Authorized Company
Representative and shall mature in such amounts and at such times as may be
necessary to provide funds when needed to make payments from the Bond Fund or
the Project Fund. The Trustee may make any and all such investments through its
own bond department or trust investment department. Any interest or gain
received from such investments shall be credited to and held in the Bond Fund or
the Project Fund and any loss from such investments shall be charged against the
Bond Fund or the Project Fund and paid by the Company at such time as there are
insufficient moneys in any such Fund to make a required payment. The Trustee
shall not be responsible or liable for any loss suffered in connection with any
investment of funds made by it in accordance with this Section 4.8 or the
provisions of Article VII of the Indenture. The provisions of this Section 4.8
shall be subject to the provisions of Section 8.10 of this Agreement and Section
510 of the Indenture.

                                   ARTICLE V.

                    TITLE TO PROJECT; PROVISIONS FOR PAYMENT

          Section 5.1. Title to the Project. The Issuer acknowledges and agrees
that it will not be vested with any interest (other than this leasehold
interest) in the Project by virtue of executing, delivering and performing this
Agreement or issuing the Bonds to finance the cost of the acquisition,
construction and installation thereof. Title to the Project shall remain in the
City subject to the Lease and this Agreement.

          Section 5.2. Payment Obligations of the Company. As rent for the
Project, the Company agrees to make prompt payment to the Trustee for the
account of the Issuer, for deposit in the Bond Fund, amounts sufficient to pay
the principal of, and the interest on, the Bonds as the same become due, as
follows: on or before the 15th day prior to each Bond Payment Date (as defined
in the Indenture) or any other date that any payment of interest, redemption
premium, if any, or principal (whether by scheduled payment or by mandatory
redemption, if any, as provided in Section 301 of the Indenture) is required to
be made in respect of the Bonds pursuant to the Indenture, until the principal
of, redemption premium, if any, and interest on the Bonds shall have been fully
paid or provision for payment thereof shall have been made in accordance with
the Indenture, in immediately available funds, a sum which will enable the
Trustee to pay the amount payable on such date (taking into account any money
then held by the Trustee and available for such payment) as principal of
(whether at maturity or upon redemption or acceleration or otherwise),
redemption premium, if any, and interest on the Bonds as provided in the
Indenture.

          All such payments shall be made to the Trustee at its principal
corporate trust office in Charlotte, North Carolina, in lawful money of the
United States of America which will be immediately available on the date each
such payment is due. Each payment shall be sufficient to pay the total amount of
principal of and interest on, the Bonds due on the succeeding Bond Payment Date.
Anything herein to the contrary notwithstanding, if on any such payment date,
the balance in the Bond Fund is insufficient to make the required payments of
principal of, and interest on, the Bonds on such date, the Company shall
forthwith pay any such deficiency.

          Should the Company fail to make the payments required under this
Section and such payments are made by the City pursuant to the terms of the
Contract between the City and the Issuer, the Company shall be obligated
hereunder to pay to the Issuer for the account and benefit of the City all such
sums so paid by the City



                                      -33-
<PAGE>   39

pursuant to the Contract with interest thereon from the date of payment by the
City at the rate of 7% per annum.

          Section 5.3. Other Payments; Trustee's Fees and Expenses. In addition
to payment of the amounts specified in Section 5.2, the Company agrees to pay to
the Trustee until payment in full of the Bonds shall have been made as rent
hereunder, (a) an amount equal to the reasonable fees and charges of the Trustee
for the Ordinary Services of the Trustee rendered and its reasonable Ordinary
Expenses incurred under the Indenture, (b) the reasonable fees and charges of
the Trustee and any other paying agent for acting as paying agent and Bond
Registrar as provided in the Indenture, as and when the same become due,
including the reasonable fees of Counsel, and (c) the reasonable fees and
charges of the Trustee for Extraordinary Services rendered by it and reasonable
Extraordinary Expenses incurred by it under the Indenture, as and when the same
become due.

          Section 5.4. Obligations of the Company Absolute and Unconditional.
The obligations of the Company and the Issuer to make the payments required in
Section 5.2 and to perform and observe the other agreements on its part
contained herein shall be absolute and unconditional and shall not be subject to
diminution by set-off, counterclaim, abatement or otherwise. Until such time as
the principal of, and the interest on, the Bonds shall have been paid in full,
the Company (a) will not suspend or discontinue any payments provided for in
Section 5.2 except to the extent the same have been prepaid, (b) will perform
and observe all its other agreements contained herein, and (c) except as
provided in Sections 10.1, 10.2 and 10.3, will not terminate this Agreement for
any cause, including, without limiting the generality of the foregoing, any acts
or circumstances that may constitute failure of consideration, sale, loss,
eviction or constructive eviction, destruction of or damage to the Project,
commercial frustration of purpose, any change in the tax or other laws of the
United States of America or of the State or any political subdivision of either,
or any failure of the Issuer to perform and observe any agreement, whether
express or implied, or any duty, liability or obligation arising out of or in
connection herewith or with the Indenture. Nothing contained in this Section
shall be construed to release the issuer from the performance of any of the
agreements on its part herein contained; and if the Issuer should fail to
perform any such agreement, the Company may institute such action against the
Issuer as the Company may deem necessary to compel performance or recover its
damages for nonperformance so long as such action shall not affect or alter the
agreements on the part of the Company contained in the preceding sentence.

          Nothing contained herein shall be construed as a waiver of any rights
which the Company may have against the Issuer under this Agreement, or against
any person under this Agreement, the Indenture or otherwise, or under any
provision of law.

                                   ARTICLE VI.

                 MAINTENANCE, MODIFICATION, TAXES AND INSURANCE

          Section 6.1. Maintenance and Modification of Project by Company.

          (a) Throughout the Lease Term the Company shall at its own expense (i)
     keep the Project in as reasonably safe condition as the operation thereof
     will permit, and (ii) keep the Leased Equipment and all other improvements
     forming a part of the Project in good repair and in good operating
     condition, making from time to time all necessary repairs thereto and
     renewals and replacements thereof.

          (b) The Company may, from time to time, in its sole discretion and at
     its own expense, make any additions, modifications or improvements to the
     Project, including installation of additional machinery, equipment, and
     related property; which it may deem desirable for its business purposes;
     provided that all such additions, modifications and improvements do not
     adversely affect the structural integrity of the building and are located
     wholly within the boundary lines of the Leased Land. All machinery,
     equipment and related property so installed by the Company shall remain the
     sole property of the Company in which neither the Issuer nor the Trustee
     shall have any interest and may be modified or removed at any time;
     provided, that any damage to the Project occasioned by such modification or
     removal shall be repaired by the Company at its own expense.

          (c) The Company shall not permit any mechanics', materialmen's,
     suppliers', vendors', or other similar lien to be established or remain
     against the Project for labor or materials furnished or services rendered
     in connection with any additions, modifications, improvements, repairs,
     renewals or replacements so made by it; provided, that if the Company shall
     first notify the Issuer of its intention so to do, the Company may in good
     faith contest any mechanics', materialmen's, suppliers', vendors' or other
     similar lien filed or established against the Project, and in such event
     may permit the items so contested to remain undischarged and unsatisfied
     during the period of such contest and any appeal therefrom unless the
     Issuer or the Trustee shall notify the Company that, in the opinion of
     independent Counsel, by nonpayment of any such items, the lien or security
     interests afforded by this Agreement will be materially endangered or the
     Project or any part thereof or the Trust Estate will be subject to loss or
     forfeiture, in which event the Company shall promptly pay and cause to be
     satisfied and discharged all such unpaid items. The Issuer will cooperate
     fully with the Company in any such contest.



                                      -35-

          Section 6.2. Taxes, Other Governmental Charges and Utility Charges.
The Issuer and the Company acknowledge that under present law, no part of the
Issuer's interest in the Project is subject to ad valorem taxation by the State
or by any political or taxing subdivision thereof, and that under present law,
the income and profits (if any) of the Issuer from the Project are not subject
to either federal or State taxation. The Issuer and the Company also acknowledge
that the Company's interest in the Leased Land and the Project is a usufruct and
not an estate for years, and therefore, the Company's interest in the Leased
Land and the Project is not subject to either federal or State taxation. The
Company shall pay, as the same become lawfully due and payable,

          (a) all taxes and governmental charges of any kind whatsoever upon or
     with respect to the interest held by the Company hereunder,

          (b) all taxes and governmental charges of any kind whatsoever upon or
     with respect to the Project or any machinery, equipment or related property
     installed or brought by the Company therein or thereon (including, without
     limiting the generality of the foregoing, any taxes levied upon or with
     respect to the income or profits of the Issuer from the Project which, if
     not paid, will become a lien on the Project prior to or on a parity with
     the security interest in favor of the Issuer created hereunder),

          (c) all utility and other charges incurred in the operation,
     maintenance, use, occupancy and upkeep of the Project, and

          (d) all assessments and charges lawfully made by any governmental body
     for public improvements that may be secured by a lien on the Project;

provided, that with respect to special assessments or other governmental charges
that may lawfully be paid in installments over a period of years, the Company
shall be obligated to pay only such installments as are required to be paid
during the Lease Term.

          The Company may, at its own expense and in its own name and behalf or
in the name and behalf of the Issuer, in good faith contest any such taxes,
assessments and other charges and, in the event of any such contest, may permit
the taxes, assessments and other charges so contested to remain unpaid during
the period of such contest and any appeal therefrom unless the Issuer or the
Trustee shall notify the Company that, in the opinion of Independent Counsel, by
nonpayment of any such items the lien or security interests afforded by this
Agreement in favor of the Issuer will be materially endangered or the Project or
any part thereof will be subject to loss or forfeiture, in which event such


                                      -36-
<PAGE>   42



taxes, assessments or charges shall be paid promptly. The Issuer shall cooperate
fully with the Company in any such contest. If the Company shall fail to pay any
of the foregoing items required by this Section to be paid by the Company, the
Issuer may (but shall be under no obligation to) pay the same, and any amounts
so advanced therefor by the Issuer shall become an additional obligation of the
Company to the Issuer, which amounts, together with interest thereon at the rate
of 8% per annum from the date thereof, the Company agrees to pay.

          Section 6.3. Insurance Required. Throughout the Lease Term the Company
shall keep the Project continuously insured against such risks as are
customarily insured against by businesses of like size and type (other than
business interruption insurance), paying as the same become due all premiums in
respect thereto, including, but not necessarily limited to:

          (a) insurance to the full insurable actual cash value of the Project
     against loss from damage by fire and lightning, with uniform standard
     extended coverage endorsement limited only as may be provided in the
     standard form of extended coverage endorsement at the time in use in the
     State, and the policies evidencing such insurance may provide that the
     Company shall be self-insured to the extent of $100,000 in connection with
     each separate claim insured against. Such self-insurance may, at the
     Company's option, be taken directly as a deductible or indirectly under any
     type of retrospective rating arrangement between the Company and such
     insurer as it may select; and

          (b) general public liability insurance against claims for bodily
     injury, death or property damage occurring on, in or about the Project and
     the adjoining streets, sidewalks, and passageways, such insurance to afford
     protection of not less than $10,000,000 with respect to bodily injury to
     any one person, not less than $10,000,000 with respect to bodily injury to
     two or more persons in any one accident, and not less than $10,000,000 with
     respect to property damage resulting from any one occurrence, and the
     policies evidencing such insurance may provide that the Company shall be
     self-insured to the extent of $100,000 in connection with each separate
     claim insured against. Such self-insurance may, at the Company's option, be
     taken directly as a deductible or indirectly under any type of
     retrospective rating arrangement between the Company and such insurer as it
     may select; and 

          (C) during the Construction Period and throughout the Lease Term, the
     Company shall maintain, or cause to be maintained in connection with the
     Project, Workers' Compensation Coverage required by then applicable law.

          With respect to the insurance required by Section 6.3(a), if the
Issuer shall disagree with the Company as to the full insurable actual cash
value of the Project, the Issuer shall have the right at its own expense to
appoint an MAI appraiser to determine such value for such purposes, and, should
the Company disagree with such appraisal, it may appoint at its own expenses a
second MAI appraiser and the two appraisers shall appoint a third MAI appraiser
(at the joint expense of the Issuer and the Company), and the appraisers shall
establish such value.

          Section 6.4. Application of Net Proceeds of insurance. The Net
Proceeds of the insurance carried pursuant to the provisions of Section 6.3
shall be applied, as follows: (a) the Net Proceeds of the insurance required in
Section 6.3(a) shall be applied as provided in Section 7.1, and (b) the Net
Proceeds of the insurance required in Sections 6.3(b) and (c) shall be applied
toward extinguishment or satisfaction of the liability with respect to which
such insurance proceeds may be paid.

          Section 6.5. Additional Provisions Respecting Insurance. All insurance
required in Section 6.3 shall be taken out and maintained in generally
recognized responsible insurance companies selected by the Company and
authorized to do business in the State. All policies evidencing such insurance
shall provide for payment of the losses for coverage required by Section 6.3(a)
and 6.3(b) to the Issuer, the Company and the City as their respective interests
may appear; provided, however, that all claims regardless of amount may be
adjusted by the Company with the insurers, subject to approval of the Issuer,
which approval shall not be unreasonably withheld, as to settlement of any claim
which is an amount which would require payment to the Issuer as aforesaid. The
insurance hereby required may be contained in blanket policies now or hereafter
maintained by the Company.

          All such policies, or a certificate or certificates of the insurers
that such insurance is in force and effect, shall be deposited with the Issuer
and the City and shall contain a provision that such policy may not be cancelled
unless the Issuer and the City are notified at least thirty (30) days prior to
cancellation; and at least thirty (30) days prior to expiration of any such
policy, the Company shall furnish the Issuer and the City with evidence
satisfactory to the latter that the policy has been renewed or replaced or is no
longer required hereby.

          The Company may fulfill its obligations to keep the Project insured
pursuant to Section 6.3 hereof and this Section 6.5 by having the Project
covered under a blanket or master policy of the City or the Issuer. In the case
of such coverage, the Issuer must assure the receipt by the Company thirty (30)
days prior notice of any changes, modifications or cancellations of insurance
coverage. The Issuer agrees to use its best efforts to procure the insurance at
the most favorable rates possible, and, 




                                      -38-
<PAGE>   44



if possible, to cause the City to provide coverage through its blanket or master
policies (in which case the cost of such insurance to the Company shall be
equitably reduced to reflect the cost savings as a result of such inclusion in
the City's or the Issuer's blanket or master policies).

          Section 6.6. Other Issuer Expenses. Anything to the contrary herein
notwithstanding, the Company shall pay any expenses not specifically mentioned
herein which are incurred by the Issuer in connection with the Project, this
Agreement, the Indenture or the Bonds, and which are not payable from the
Project Fund pursuant to Section 4.3.

          The provisions of this Section shall survive the termination of this
Agreement.

          Section 6.7. Advances by Issuer or City. If the Company fails to
maintain the full insurance coverage required hereby or fails to keep the
Project in as reasonably safe condition as its operating conditions will permit,
or fails to keep the Project and the Leased Equipment in good repair and good
operating condition, the Issuer or the City may (but unless satisfactorily
indemnified shall be under no obligation to) take out the required policies of
insurance and pay the premiums on the same or make the required repairs,
renewals and replacements; and all amounts so advanced therefor by the Issuer or
the City will become an additional obligation of the Company to the one making
the advancement, which amounts, together with interest thereon at the rate per
annum borne by the Bonds from the date thereof, the Company agrees to pay.

          The provisions of this Section shall survive the termination of this
Agreement.

                                   ARTICLE VII

                      DAMAGE, DESTRUCTION AND CONDEMNATION

          Section 7.1. Damage and Destruction. If prior to payment in full of
the Bonds the Project is damaged by fire or other casualty, the Company at its
option shall have the right to use the Net Proceeds of insurance resulting from
such claims for losses to either (a) redeem the Bonds, or (b) replace, repair,
rebuild or restore the Project as hereinafter set forth.

          The Company shall make such election within ninety (90) days following
any such loss by giving written notice to the issuer and the City.

          In the event the Company elects to redeem the Bonds, the Net Proceeds
of insurance attributable to (x) the contents of the Project exclusive of the
Leased Equipment described in Exhibit "B" hereto and (y) the improvements on the
Leased Land belonging to the Company present on the Leased Land as of May 1,
1993 shall promptly be paid to the Company, and all other Net Proceeds of
insurance shall promptly upon receipt thereof be applied (without any investment
thereof) to the redemption of the Bonds, and any remainder of Net Proceeds after
providing for the redemption of the Bonds in full shall be paid, in the event
the Company does not elect to replace, repair, rebuild or restore the property,
to restoring the site of the Project to developable condition and the balance
shall be paid to the Company, the Issuer and the City as their respective
interests may appear.

          In the event the Company elects to replace, repair, rebuild or restore
the property,

          (i) the Net Proceeds of insurance attributable to (x) the contents of
     the Project exclusive of the Leased Equipment described in Exhibit "B"
     hereto and (y) the improvements on the Leased Land belonging to the Company
     present on the Leased Land as of May 1, 1993 shall promptly be paid to the
     Company, (ii) all other Net Proceeds of insurance shall promptly upon
     receipt thereof be deposited in a special trust account with the issuer and
     made available to the Company to replace, repair, rebuild or restore,

          (ii) the Company, or the Issuer at the Company's direction, shall
     proceed promptly to replace, repair, rebuild or restore the property
     damaged or destroyed to substantially the same condition as existed prior
     to the event causing such damage or destruction, with such changes,
     alterations and modifications (including the substitution and addition of
     other property) as may be desired by the Company and as will not impair the
     operating unity or productive capacity of the 



                                      -40-
<PAGE>   46

     Project or change its character to such an extent that its ownership by the
     issuer would not be permitted under the laws pursuant to which the Issuer
     then exists, and

          (iii) the issuer shall apply so much as may be necessary of the Net
     Proceeds of such insurance to the payment of the costs of such replacement,
     repair, rebuilding or restoration, either on completion thereof or as the
     work progresses, as directed by the Company.

Each such direction of the Company shall be accompanied by a certificate of an
architect or engineer (or, in the case of a loss of $25,000 or less, the
Company), which architect or engineer shall be selected by the Company and
satisfactory to the City, in charge of the replacement, repair, rebuilding or
restoration, dated not more than thirty (30) days prior to such direction,
setting forth in substance that

          (A) the sum then directed to be applied either has been paid by the
     Company, or is justly due, to contractors, subcontractors, materialmen,
     engineers, architects or other persons who shall have rendered services or
     furnished materials or improvements for the replacement, repair, rebuilding
     or restoration therein specified; the names of such persons; a brief
     description of such services or materials or improvements and the several
     amounts so paid or due to each of such persons; and, a statement that none
     of the costs of the services or materials or improvements described in such
     certificate has been or is being made the basis, in any previous or then
     pending direction, for payment under this Section and that the sum then
     directed to be applied does not exceed the value of the services or
     materials or improvements described in the certificate, and

          (B) except for the amount, if any, stated (pursuant to (A) preceding)
     in such certificate to be due for services or materials or improvements,
     there is not outstanding any indebtedness known to the persons signing such
     certificate which is then due for labor, services, material, supplies
     and/or equipment in connection with the replacement, repair rebuilding or
     restoration which, if unpaid, might become the basis of mechanics',
     materialmen's, suppliers' and vendors, liens or other similar liens (other
     than those being contested in good faith as permitted herein upon the
     Project or any part thereof).

The Issuer may conclusively rely upon such direction and shall have no liability
or responsibility for payments made pursuant to this Section in reliance
thereon. If said Net Proceeds are not sufficient to pay in full the costs of
such replacement, repair, rebuilding or restoration, the Company shall
nonetheless complete the same and shall pay that portion of the costs thereof in
excess 


                                      -41-
<PAGE>   47



of the amount of said Net Proceeds or shall advance to the Issuer the moneys
necessary to complete said work, in which case the Issuer shall proceed so to
complete the work. The Company shall not, by reason of the payment of such
excess costs (whether by direct payment thereof or advances to the Issuer), be
entitled to any reimbursement from the Issuer or the City or any diminution in
or postponement or abatement of the Rents payable under Section 5.2.

          Any balance of said Net Proceeds remaining after payment of all the
costs of such replacement, repair, rebuilding or restoration shall be paid into
the Bond Fund. If payment in full of the Bonds has been made, all Net Proceeds
shall be paid to the Issuer for the benefit of the Company.

          Section 7.2. Condemnation. If the title in and to, or the temporary
use of, the Project or any part thereof shall be taken under the exercise of the
power of eminent domain by any governmental body or by any other person acting
under governmental authority, or the Project or any part thereof is sold in lieu
of such exercise of the power of eminent domain, the Company shall be obligated
to continue to pay the rents specified in Section 5.2. The Issuer shall cause
the Net Proceeds received by it and the City, from any award made in such
eminent domain proceeding, or from any proceeds of a sale in lieu thereof, to be
applied in one or more of the following ways as shall be directed in writing by
the Company:

          (a) the restoration of the improvements of the Project to
     substantially the same condition as existed prior to the exercise of such
     power of eminent domain, with such changes, alterations and modifications
     (including the substitution and addition of other property) as may be
     desired by the Company, provided that such changes, alterations and
     modifications do not adversely affect or impair the structural integrity of
     the building or change the Project's character to such an extent that the
     Project would not constitute a "project" within the meaning of the Act and
     that all such changes, alterations and modifications are located within the
     boundaries of the Leased Land;

          (b) the acquisition, by construction or otherwise, by the Issuer of
     other improvements on any remaining portion of the Leased Land suitable for
     the Company's operations at the Project, provided that such improvements do
     not adversely affect or impair the structural integrity of the building or
     change the Project's character to such an extent that the Project would not
     constitute a "project" within the meaning of the Act and that all such
     improvements are located within the boundary lines of the Leased Land. All
     such improvements to the Project shall inure to and become part of the
     Project; 




                                      -42-
<PAGE>   48



          (c) redemption of the Bonds together with accrued interest thereon to
     the date of redemption; provided, that no part of any such condemnation
     award or proceeds of a sale in lieu thereof may be applied for such
     redemption unless (1) the Bonds are to be redeemed in whole in accordance
     with the Indenture upon exercise by the Company of its option to direct
     redemption of the Bonds provided by Section 10.1(b), or (2) if less than
     all of the Bonds are to be redeemed, the Company shall furnish to the
     Issuer and the City a certificate of an Independent Engineer (who shall be
     selected by the Company and be acceptable to the City and the Issuer)
     stating (i) that the property forming a part of the Project that was taken
     in such eminent domain proceeding is not essential to the Company's use or
     occupancy of the Project, (ii) that the Project has been restored to a
     condition substantially equivalent to its condition prior to the taking in
     such eminent domain proceeding, or (iii) that improvements have been
     acquired which are suitable for the Company's operations at the Project as
     contemplated by the foregoing subsection (b) of this Section; or

          (d) payment into the Bond Fund or, if payment in full of the Bonds has
     been made, to the Company.

          Within ninety (90) days from the date of entry of a final order in any
eminent domain proceeding granting condemnation or a sale in lieu of
condemnation, the Company shall direct the Issuer and the City in writing as to
which way or ways specified in this Section the Company elects to have the
condemnation award applied. The direction of the Company shall, in the case of a
restoration under Section 7.2(a) or the acquisition or construction of
improvements under Section 7.2(b), be accompanied by a certificate similar to
that required in Section 7.1. The Issuer may conclusively rely upon such
direction and shall have no liability for payments made pursuant to this Section
in reliance thereon.

          The Company shall take or cause to be taken such action, if any, as
may be necessary to perfect the lien and security interest of the Issuer with
respect to any improvements of the Project pursuant to this Section.

          The Issuer shall cooperate fully with the Company in the handling and
conduct of any prospective or pending eminent domain proceeding with respect to
the Project or any part thereof and shall, to the extent it may lawfully do so,
permit the Company to litigate in any such proceeding in the name and on behalf
of the Issuer. In no event will the Issuer voluntarily settle, or consent to the
settlement of, any prospective or pending eminent domain proceeding with respect
to the Project or any part thereof without the written consent of the Company
and the Trustee.

<PAGE>   49





          In the event the Company elects to redeem the Bonds, the Net Proceeds
of condemnation proceeds shall promptly upon receipt thereof be applied (without
any investment thereof) to the redemption of the Bonds.

          In the event the Company elects to replace, repair, rebuild or restore
the property, the Net Proceeds of condemnation proceeds shall promptly upon
receipt thereof be deposited in a special trust account with the Issuer and made
available to the Company for such purpose.

          Section 7.3. Condemnation of Company-Owned Property. The Company shall
be entitled to the proceeds of any condemnation award or portion thereof made
for damages to or taking of its own property or for damages on account of the
taking of or interference with the Company's rights to possession, use or
occupancy of the Project.

                              PARTICULAR AGREEMENTS

          Section 8.1. No Warranty of Condition or Suitability by the Issuer.
THE ISSUER MAKES NO WARRANTY, EITHER EXPRESS OR IMPLIED, AS TO THE CONDITION OF
THE PROJECT OR THAT IT WILL BE SUITABLE FOR THE COMPANY'S PURPOSES OR NEEDS. The
Company releases the Issuer from, agrees that the Issuer shall not be liable for
and agrees to hold the Issuer harmless against, any loss or damage to property
or any injury to or death of any person that may be occasioned by any cause
whatsoever pertaining to the Project or the use thereof.

          Section 8.2. Inspection of the Project. The Company agrees that the
City, the Issuer and the Trustee and their duly authorized agents who are
acceptable to the Company shall have the right at reasonable times during
business hours, subject to the Company's usual safety and security requirements
for persons on the Leased Land, to enter upon the Leased Land and to examine and
inspect the Project without interference or prejudice to the Company's
operations; provided, however, that any such right of inspection shall be solely
for the purpose of determining the Company's compliance with this Agreement.
Before exercising any such right of inspection, the Issuer or the Trustee, as
the case may be, shall first give notice, written or oral, to the Company at
least three (3) hours prior to making the requested inspection of the Project.

          The Company further agrees that the City, the Issuer and its duly
authorized agents who are acceptable to the Company shall have such rights of
access to the Project as may be reasonably necessary to cause to be completed
the acquisition, construction and installation of the Project.

          Section 8.3. Indemnification of Issuer and Trustee. The Company shall
indemnify and save the Issuer and its directors, officers and employees, and the
Trustee and its directors, officers, employees, agents and affiliates harmless
against and from all claims by or on behalf of any person, firm or corporation
arising from the conduct or management of, or from any work or thing done on,
the Project during the term of this Agreement, and against and from all claims
arising during the term of this Agreement from

          (a) any condition of the Project caused by the Company,

          (b) any failure on the part of the Company in the performance of any
     of its obligations hereunder,



                                      -45-
<PAGE>   51



          (c) any contract entered into by the Company or by the Issuer with the
     written consent of the Company in connection with the acquisition,
     construction and installation of the Project,

          (d) any act of negligence of the Company or of its agents,
     contractors, servants, employees or licensees, and

          (e) any act of negligence of any assignee or sublessee of the Company,
     or of any agent, contractor, servant, employee or licensee of any assignee
     or sublessee of the Company.

The Company shall indemnify and save the Issuer (including its directors,
officers and employees) harmless from and against all costs and expenses
incurred in or in connection with any action or proceeding brought thereon, and
upon notice from the Issuer, the Company shall defend the Issuer in any such
action or proceeding. This indemnification shall not extend to the Issuer for
actions undertaken in negligence or bad faith.

and expenses incurred in or in connection with any action or proceeding brought
thereon, and upon notice from the Trustee, the Company shall defend the Trustee
in any such action or proceeding. This indemnification shall not extend to the
Trustee for actions undertaken in negligence or bad faith.

          The Company agrees to pay to the Trustee any and all sums of money
required to be paid by the Issuer pursuant to Section 1002 of the Indenture.

          The provisions of this Section shall survive the termination of this
Agreement.

          Section 8.4. Maintenance of Corporate Existence; Qualification in the
State. The Company agrees that so long as any Bonds remain outstanding it shall
maintain its corporate existence and shall not merge or consolidate with any
other corporation and shall not transfer or convey all or substantially all of
its property, assets and licenses; provided, however, the Company may, without
violating any provision hereof, consolidate with or merge into another domestic
corporation (i.e., a corporation incorporated and existing under the laws of one
of the states of the United States of America or the District of Columbia) or
permit one or more other domestic corporations to consolidate with or merge into
it, or transfer all or substantially all of its assets to another domestic
corporation, but only on the condition that ration, but only on the condition
that


                                      -46-
<PAGE>   52



          (a) the assignee corporation or the corporation resulting from or
     surviving such merger (if other than the Company) or consolidation or the
     corporation to which such transfer is made is in compliance with the terms
     of the second paragraph of this Section and shall expressly assume in
     writing and agree to perform all of the Company's obligations hereunder,
     and

          (b) in connection with any such consolidation or merger there shall
     be filed with the Issuer and the Trustee a letter from an independent
     certified public accountant (or firm thereof) satisfactory to the Trustee
     certifying that immediately after the consummation of such consolidation,
     merger or transfer the corporation resulting from or surviving such
     consolidation or merger or the corporation to which such transfer is made
     will have an aggregate stockholders' equity at least equal the aggregate
     stockholders' equity of the Company as of March 31, 1993.

If the Company is the surviving corporation in such a consolidation or merger,
the express assumption referred to in (a) above shall not be required, but the
letter of an independent certified public accountant (or firm thereof) shall be
filed as indicated in (b) above.

          The Company warrants (i) that it is and throughout the term hereof it
will continue to be qualified to do business in the State, and (ii) that if it
elects to consolidate with, merge into or transfer all or substantially all of
its assets to another corporation in accordance with this Section, and such
other corporation is not organized under the laws of the State, the Company, as
a condition of such consolidation, merger or transfer of assets, shall cause
such other corporation to qualify to do business as a foreign corporation in the
State and to remain so qualified continuously during the term hereof.

          The Company shall preserve and keep in full force and effect all
licenses and permits necessary to the proper conduct of its business.

          Section 8.5. Assignment and Subleasing. This Agreement may be
assigned, and the Project may be subleased as a whole or in part, by the Company
without the necessity of obtaining the consent of either the Issuer or the City,
subject, however, to the following conditions:

          (1) the Company shall remain primarily liable for its obligations
     hereunder, including the payment of the rents specified in Section 5.2
     hereof and the performance and observance of the other agreements on its
     part herein contained;




                                      -47-
<PAGE>   53



          (2) the assignee or sublessee shall assume the obligations of the
     Company hereunder (including specifically, but without limitation, all
     covenants required to maintain the tax-exempt status of the Bonds) to the
     extent of the interest assigned or subleased;

          (3) the Company shall, within thirty (30) days after the delivery
     thereof, furnish or cause to be furnished to the Issuer and to the City a
     true and complete copy of each such assignment and sublease, as the case
     may be; and

          (4) any assignee or sublessee shall elect and waive in writing
     satisfactory to the Issuer any rights to claim depreciation or investment
     tax credit with respect to the Project or the Leased Land.

          Section 8.6. Annual Audit; Financial Information. The Company agrees
to have an annual audit made by an independent certified public accountant (or
firm thereof) and to furnish to the Issuer and the City either a copy of such
audit promptly upon its completion or a copy of the Company's annual report to
its stockholders if such annual report shall contain financial statements of
substantially similar detail and similarly prepared and certified.

          Section 8.7. Agreement of Issuer Not to Assign or Pledge. The Issuer
agrees that except for granting to the City a security interest in the Issuer's
rights hereunder, it will not attempt to assign, pledge, transfer or convey its
interest in or create any assignment, pledge, lien, charge or encumbrance of any
form or nature with respect to this Agreement so long as the Company is not in
default hereunder.

          Section 8.8. Redemption of Bonds. The Issuer or the Trustee, at the
request at any time of the Company and if the same are then redeemable, shall
forthwith take all steps that may be necessary under the applicable redemption
provisions of the Indenture to effect redemption of all or any portion of the
Bonds, as may be specified by the Company, on the earliest redemption date on
which such redemption may be made under such applicable provisions or upon the
date set for the redemption by the Company pursuant to Sections 10.1 and 10.2.
As long as the Company is not in default hereunder and the Issuer is not
obligated to call Bonds pursuant to the terms of the Indenture, neither the
Issuer nor the Trustee shall redeem any Bond prior to its stated maturity unless
requested to do so in writing by the Company.

          Section 8.9. Reference to Bonds Ineffective After Bonds Paid. Upon
payment in full of the Bonds and all fees and charges of the Trustee, all
references herein to the Bonds and the Trustee shall be ineffective, and neither
the Trustee nor the holders of any of the Bonds shall thereafter have any rights
hereunder,

saving and excepting those that shall have theretofore vested and any right of
the Issuer or the Trustee to indemnification under Section 8.3, which right
shall survive the payment of the Bonds and the termination of this Agreement.
Reference is hereby made to Section 802 of the Indenture which sets forth the
conditions upon the existence or occurrence of which payment in full of the
Bonds shall be deemed to have been made. Upon payment in full of the Bonds and
all fees and charges of the Trustee, the Company may elect to continue as lessee
of the Project under the provisions of this Agreement, with no further rental
payments due after prepayment of the rental installments provided in Section 5.2
hereof. In the case of such an election, all rights and obligations of the
Company, as lessee, and the Issuer, as lessor, shall continue hereunder until
midnight on May 1, 2018. The Company shall then have the option to renew the
Lease Term for one seven-year period at fair market value at the time the option
is exercised.

          Section 8.10. Covenants of Company and Issuer with Respect to
Exemption of Interest from Federal Income Taxation. The Bonds are being issued
by the Issuer in compliance with the conditions necessary for the interest
income on the Bonds to be exempt from federal income taxation pursuant to the
provisions of Sections 103(a), 103(b)(1), 141(d)(1)(A) and 142(a) of the Code
relating to "exempt facility bonds" issued as part of an issue 95% of the net
proceeds of which are to be used to provide funds for the construction of a new
airport hangar. It is the intention of the parties hereto that the interest on
the Bonds be and remain excludable from gross income for federal income tax
purposes, and, to that end, the Issuer and the Company do hereby covenant with
each other, the Trustee and each of the holders of any Bonds, as follows:

          (a) that the Issuer will not cause and the Company will not cause or
     permit the proceeds of the Bonds to be used in a manner which will cause
     the interest on the Bonds to lose the exemption from federal income
     taxation conferred by Sections 103(a), 103(b)(1), 141(e) and 142(a) of the
     Code;

          (b) that, during the term of this Agreement, the Company will fully
     comply with all effective rules, rulings and regulations promulgated by the
     Department of the Treasury or the Internal Revenue Service, with respect to
     bonds issued under Section 142 of the Code so as to maintain the tax-exempt
     status of the interest payable on the Bonds;

          (c) that the Company will make no change in the plans and
     specifications for the Project which would result in (i) the Project not
     being a "project" within the meaning of the Act or an airport exempt
     facility under the Code, or (ii) a violation of the limitation on maturity
     of the Bonds under Section 147(b) of the Code;




                                      -49-
<PAGE>   55



          (d) that no portion of the Project will be used as office space for
     individuals who are not employees of a governmental unit or of the Issuer
     other than office space that is directly related to the day-to-day
     operations at the Project and that is located at or within the Project; and

          (e) that at no time will:

               (i) any portion of the net proceeds of the sale of the Bonds be
          used to provide any airplane, skybox, or other private luxury box, any
          health club facility, any facility primarily used for gambling, or any
          store the principal business of which is the sale of alcoholic
          beverages for consumption off premises; or

               (ii) any portion of the proceeds of the Bonds be used to provide
          any lodging facility, any retail facility (including food and beverage
          facilities) in excess of a size necessary to serve passengers and
          employees at the "exempt facility" (as defined in Section 142(a) of
          the Code), any retail facility (other than parking) for passengers or
          the general pubic located outside the exempt facility terminal, any
          office building for individuals who are not employees of a
          governmental unit or of the operating authority for the exempt
          facility, or any industrial park or manufacturing facility; or

               (iii) any portion of the proceeds of the sale of the Bonds be
          used (directly or indirectly) for the acquisition of land (or an
          interest therein) to be used for farming purposes, or 25% or more of
          the net proceeds of the sale of the Bonds be used (directly or
          indirectly) for the acquisition of land other than land to be used for
          farming purposes; or

               (iv) any portion of the net proceeds of the sale of the Bonds be
          used for the acquisition of any property or any interest therein,
          other than land or an interest in land as provided in the preceding
          subparagraph, unless the first use of such property is pursuant to
          such acquisition; provided, however, that this limitation shall not
          apply with respect to any building (and the equipment therefor) if
          "Rehabilitation Expenditures" (hereinafter defined) with respect to
          such building equal or exceed fifteen percent of the portion of the
          cost of acquiring such building (and equipment) financed with proceeds
          of the Bonds; or, in the case of structures other than a building, if
          Rehabilitation Expenditures with respect to such structure equal or
          exceed one hundred percent of the portion of the cost of



                                      -50-
<PAGE>   56


          acquiring such structure financed with the proceeds of the Bonds. The
          term "Rehabilitation Expenditures" means any amount properly
          chargeable to the capital account of the Company or a successor to the
          Company or by the seller under a sales contract with the Company for
          the property acquired in connection with the rehabilitation of such
          property, or in the case of property constituting equipment, in
          connection with the replacement of such equipment with equipment
          having substantially the same function, excluding, however, (A)
          expenditures described in Section 48(g)(2)(B) of the Code and (B)
          amounts incurred after the date two years after the later of the date
          of acquisition of the property in question or the date of issuance and
          delivery of the Bonds; or

               (v) any Bond be held by a person who is a substantial user of the
          facilities or by a related person of such substantial user (as
          "Related Person" is defined in Section 147(a)(2) of the Code).

          Section 8.11. Non-Arbitrage Covenant. The Company and the Issuer each
covenants that it shall take no action, nor shall the Company approve the
Trustee's taking any action or making any investment or use of the proceeds of
the Bonds or any other moneys which may arise out of, or in connection with,
this Agreement, the Indenture or the Project, which would cause the Bonds to be
treated as "arbitrage bonds" within the meaning of Section 148 of the Code.
Without limiting the generality of the foregoing, the Company covenants and
agrees to comply with the requirements of Section 148(d)(3) and Section 148(f)
of the Code as it may be applicable to the Bonds or the proceeds derived from
the sale of the Bonds or any other moneys which may arise out of or in
connection with, this Agreement, the Indenture or the Project.

          Section 8.12. Depreciation Election. The Company hereby makes an
irrevocable election, binding on the Company and all successors in interest
under this Agreement, not to claim depreciation or an investment tax credit with
respect to the Project. This covenant is intended to be a covenant running with
the land and this Agreement shall be recorded in the records of the Clerk of the
Superior Court of Bibb County.

                       EVENTS OF DEFAULT AND REMEDIES

                 Section 9.1. Events of Default Defined. The following shall be
"events of default" hereunder and the term "event of default" shall mean,
whenever it is used herein, any one or more of the following events:

                 (a)      failure by the Company to make any payment required
         to be made hereunder when the same becomes due and payable but in any
         event, by five days prior to a Bond Payment Date;

                 (b)      failure by the Company to observe and/or perform any
         agreement hereunder or under the Lease (to which it is a signatory) on
         its part to be observed and/or performed, other than as referred to in
         subsection (a) of this Section, for a period of thirty (30) days after
         written notice, specifying such failure and requesting that it be
         remedied, given to the Company by the Issuer, unless the Issuer shall
         agree in writing to an extension of such time prior to its expiration;
         provided, however, if the failure stated in the notice cannot be
         corrected within the applicable period, the Issuer will not
         unreasonably withhold its consent to an extension of such time if it
         is possible to correct such failure and corrective action is
         instituted by the Company within the applicable period and diligently
         pursued until the failure is corrected; or in the case of any such
         default which can be cured with due diligence but not within such
         thirty-day period, the Company's failure to proceed promptly to cure
         such default and thereafter prosecute the curing of such default with
         due diligence;

                 (c)      any representation by or on behalf of the Company
         contained in this Agreement or in any instrument furnished in
         compliance with or in reference to this Agreement or the Indenture
         proves false or misleading in any material respect as of the date of
         the making or furnishing thereof;

                 (d)      the Company shall (i) apply for or consent to the
         appointment of, or the taking of possession by, a receiver, custodian,
         trustee or liquidator of the Company or of all or a substantial part
         of its property, (ii) admit in writing its inability, or be generally
         unable, to pay its debts as such debts become due, (iii) make a
         general assignment for the benefit of its creditors, (iv) commence a
         voluntary case under the Federal Bankruptcy Code (as now or hereafter
         in effect), (v) file a petition seeking to take advantage of any other
         law relating to bankruptcy, insolvency, reorganization, winding-up, or
         composition or adjustment of debts, (vi) fail to controvert in a
         timely or appropriate manner, or acquiesce

                                      -52-
<PAGE>   58
         in writing to, any petition filed against the Company in an
         involuntary case under said Federal Bankruptcy Code, or (vii) take any
         corporate action for the purpose of effecting any of the foregoing;

                 (e)      a proceeding or case shall be commenced, without the
         application or consent of the Company, in any court of competent
         jurisdiction, seeking (i) the liquidation, reorganization,
         dissolution, winding-up, or composition or adjustment of debts, of the
         Company, (ii) the appointment of a trustee, receiver, custodian,
         liquidator or the like of the Company or of all or any substantial
         part of its assets, or (iii) similar relief in respect of the Company
         under any law relating to bankruptcy, insolvency, reorganization,
         winding-up, or composition or adjustment of debts, and such proceeding
         or case shall continue undismissed, or an order, judgment or decree
         approving or ordering any of the foregoing shall be entered and
         continue unstayed and in effect, for a period of sixty (60) days from
         commencement of such proceeding or case or the date of such order,
         judgment or decree, or an order for relief against the Company shall
         be entered in an involuntary case under said Federal Bankruptcy Code;
         or

                 (f)      an "event of default" occurs and is continuing under 
         the Indenture.

                 The foregoing provisions of subsection (b) of this Section are
subject to the following limitations: If by reason of force majeure the Company
is unable in whole or in part to carry out the agreements on its part therein
referred to, the failure to perform such agreements due to such inability shall
not constitute an event of default nor shall it become an event of default upon
appropriate notification to the Company and/or the passage of the stated period
of time. The term force majeure as used herein shall mean, without limitation,
the following: acts of God; strikes, lockouts or other industrial disturbances;
acts of public enemies; orders of any kind of the government of the United
States of America or of the State or any of their departments, agencies,
political subdivisions or officials, or any civil or military authority;
insurrections; riots; epidemics; landslides; lightning; earthquakes; fires;
hurricanes; tornadoes; storms; floods; washouts; droughts; arrests; restraint
of government and people; civil disturbances; explosions; breakage or accident
to machinery, transmission pipes or canals; partial or entire failure of
utilities; or any other cause or event not reasonably within the control of the
Company. The Company agrees, however, to remedy with all reasonable dispatch
the cause or causes preventing the Company from carrying out its agreements;
provided, that the settlement of strikes, lockouts and other industrial
disturbances shall be entirely within the discretion of the Company, and the
Company shall not be required to make settlement of strikes,

                                      -53-
<PAGE>   59
lockouts and other industrial disturbances by acceding to the demands of the
opposing party or parties when such course is, in the judgment of the Company,
unfavorable to the Company.

                 Section 9.2. Remedies. Whenever an event of default shall have
happened and be continuing, the Issuer may take any one or more of the
following remedial steps:

                 (a)      The Issuer may declare all installments of rent
         payable under Section 5.2 for the remainder of the Lease Term to be
         immediately due and payable, whereupon the same shall become
         immediately due and payable.  If the Issuer elects to exercise the
         remedy afforded in this subsection (a) and accelerates all rents
         required to be paid under Section 5.2 for the remainder of the Lease
         Term, the amount then due and payable by the Company as accelerated
         payments shall be the sum of (i) the aggregate principal amount of the
         outstanding Bonds, (ii) all interest on the Bonds then due and (iii)
         all other amounts due and payable to the bondholders and/or to the
         Trustee with respect to the payment of the Bonds, including reasonable
         Counsel fees;

                 (b)      The Issuer may re-enter and take possession of the
         Project without terminating the Lease Term and without any liability
         to the Company for such entry and repossession, and sublease the
         Project for the account of the Company, holding the Company liable for
         the difference in the rents and other amounts payable by such
         sublessee in such subleasing and the rents and other amounts payable
         by the Company hereunder;

                 (c)      The Issuer may terminate the Lease Term, exclude the
         Company from possession of the Project and use its best efforts to
         lease the Project to another for the account of the Company, holding
         the Company liable for all rents and other amounts payable by the
         Company hereunder up to the effective date of such leasing; and

                 (d)      The Issuer may take whatever action at law or in 
         equity may appear necessary or desirable to collect any sums then due 
         and thereafter to become due hereunder or to enforce performance and 
         the observance of any agreement of the Company hereunder.

In the event of an acceleration of the Bonds, all payments due under Section
5.2 hereunder shall be and become immediately due and payable without notice or
demand; provided, however, that in no event shall the Company be excluded from
possession of the Project pursuant to subsection (c) above until the Company
has been given notice of such termination of the Lease Term and thirty (30)
days to pay the amount provided for in subsection (a) above, which thirty (30)
day period shall begin to run upon the later of

                                      -54-
<PAGE>   60
(1) the receipt of notice of acceleration pursuant to subsection (a) above, or
(2) the receipt of notice of termination of the Lease Term pursuant to
subsection (c) above. Any amounts collected pursuant to action taken under this
Section shall be paid into the Bond Fund and applied in accordance with the
provisions of the Indenture and after payment in full of the Bonds and the
payment of any costs occasioned by an event of default hereunder, any excess
moneys in the Bond Fund shall be returned to the Company as an overpayment of
rents.

                 Section 9.3. No Remedy Exclusive. Subject to Section 7.2(d)
hereof, no remedy herein conferred upon or reserved to the Issuer is intended
to be exclusive of any other remedy, but each and every such remedy shall be
cumulative and shall be in addition to every other remedy hereunder or now or
hereafter existing at law, in equity or by statute. No delay or omission to
exercise any right or power accruing upon the occurrence of any event of
default shall impair any such right or power or shall be construed to be a
waiver thereof, but any such right or power may be exercised from time to time
and as often as may be deemed expedient.

                 Section 9.4. Agreement to Pay Counsel Fees and Expenses. If
there should occur a default or an event of default hereunder and the Issuer
should employ Counsel or incur other expenses for the collection of sums due
hereunder or the enforcement of performance or observance of any agreement on
the part of the Company herein contained, the Company agrees that it will on
demand therefor pay to the Issuer the reasonable fee of such Counsel and such
other reasonable expenses so incurred by the Issuer.

                 The provisions of this Section shall survive the termination
of this Agreement.

                           PREPAYMENT UNDER AGREEMENT

                 Section 10.1. Option to Prepay Rental Payments Under Agreement
in Whole in Certain Events. So long as the Company is not in default hereunder,
the Company shall have, and is hereby granted, the option to prepay the rents
required to be made under Section 5.2 if any of the following shall have
occurred:

                 (a)      the Project shall have been damaged or destroyed to
         such an extent that the Company is thereby prevented from carrying on
         its normal operations at the Project for a period of six (6)
         consecutive months;

                 (b)      title in and to, or the temporary use of, all or
         substantially all of the Project shall have been taken under the
         exercise of the power of eminent domain by any governmental authority,
         or person acting under governmental authority (including such a taking
         as, in the judgment of the Company, results in the Company being
         prevented thereby from carrying on its normal operations at the
         Project for a period of three (3) consecutive months); or

                 (c)      as a result of any changes in the Constitution of the
         State or the Constitution of the United States of America or by
         legislative or administrative action (whether State or Federal) or by
         final decree, judgment, decision or order of any court or
         administrative body (whether State or Federal), this Agreement shall
         have become void or unenforceable or impossible of performance in
         accordance with the intent and purposes of the parties as expressed
         herein.

To exercise such option, the Company (i) shall, within ninety (90) days
following the event giving rise to the Company's desire to exercise such
option, deliver to the Issuer and to the Trustee a certificate, executed by an
officer of the Company, stating (A) the event giving rise to the exercise of
such option, (B) that the Company has directed the Trustee to redeem all of the
Bonds in accordance with the provisions of the Indenture, and (C) the date upon
which such prepayment is to be made, which date shall not be less than
forty-five (45) days nor more than ninety (90) days from the date such notice
is mailed; and (ii) shall make arrangements satisfactory to the Trustee for the
giving of the required notice of redemption.

                 The prepayment price which shall be paid to the Trustee by the
Company on or prior to its exercise of the option granted in this Section shall
be the sum of the following:

                                      -56-
<PAGE>   62
                 (1)      an amount of money which, when added to the amount
         then on deposit in the Bond Fund, will be sufficient to pay and redeem
         all of the then outstanding Bonds on the earliest applicable
         redemption date including, without limitation, principal plus accrued
         interest thereon to said redemption date, plus

                 (2)      an amount of money equal to the Trustee's and paying
         agents' fees and expenses under the Indenture accrued and to accrue
         until such final payment and redemption of the Bonds.

                 Section 10.2.  Other Options to Prepay Rental Payments Under
Agreement. The Company shall have, and is hereby granted, the option to prepay
the rents required to be made under Section 5.2 in whole, at any time, or in
part on any Bond Payment Date (as defined in the Indenture), by (i) depositing
irrevocably with the Trustee for the account of the Issuer sufficient moneys to
pay the principal of and interest on all of the Bonds due and to become due on
or prior to the redemption date (if the Bonds are to be redeemed) or maturity
thereof, (ii) paying to the Trustee all Trustee's fees and expenses due in
connection with the payment or redemption of any such Bonds, and (iii) if any
Bonds are to be redeemed on any date prior to their maturity, giving the
Trustee irrevocable instructions to redeem such Bonds on such date and either
evidence satisfactory to the Trustee that all redemption notices required by
the Indenture have been given or irrevocable power authorizing the Trustee to
give such redemption notices.

                 Section 10.3. Obligation to Prepay Rental Payments Under
Agreement Under Certain Circumstances. If there occurs a Determination of
Taxability, not later than six (6) months following the date of such
Determination of Taxability, the Company shall be obligated to, as promptly as
practical, pay to the Trustee for the account of the Issuer for deposit in the
Bond Fund, the following:

                 (a)      For application by the Trustee to the redemption of
         Bonds which are outstanding on the date of such Determination of
         Taxability and which will not mature or otherwise be redeemed prior to
         the redemption date contemplated by this Section:

                          (i)  the principal amount of such Bonds plus accrued 
                 interest to such redemption date; plus

                          (ii) an additional amount equal to one-half (1/2) the
                 interest paid and/or accrued on each such Bond during the
                 Taxable Period;

                 (b)      To be paid by the Trustee to the holders of Bonds
         which are outstanding on the date of the Event of Taxability

                                      -57-

         and which will mature or will be redeemed prior to the redemption date
         provided for in this Section, an additional amount equal to one-half
         (1/2) the interest paid and/or accrued on each such Bond during the
         Taxable Period.

                          Said accelerated payments shall also include expenses
         of redemption and the fees and expenses of the Trustee and the paying
         agent(s) accrued and to accrue until such final payment and redemption
         of the Bonds.

         Issuer and the Trustee of (i) the filing by the Company of any
         Supplemental Statement which shows that an Event of Taxability has
         occurred, and (ii) its receipt of any oral or written advice from the
         Internal Revenue Service that an Event of Taxability has occurred.

                 Promptly upon receipt of written notice of the occurrence of a
Determination of Taxability, the Trustee shall cause notice thereof to be given
to the bondholders in the same manner as is provided in the Indenture for
notices of redemption. In such notice to bondholders, the Trustee may make
provisions for obtaining advice from bondholders, in such form as shall be
deemed appropriate, respecting relevant assessments made on such bondholders by
the Internal Revenue Service, so as to be able, if appropriate, to verify the
existence, present or future, of a Determination of Taxability.

                 The Company shall immediately instruct the Trustee to apply
the accelerated payments made by the Company as a result of such Determination
of Taxability, together with any moneys then held by the Trustee, in the order
of priority set forth in Section 504 of the Indenture, on the earliest possible
date after the giving of the required notice of redemption under the Indenture,
to the redemption of Bonds or to the payment to the holders of Bonds which will
mature or will be redeemed prior to the redemption date contemplated by this
Section, all in accordance with the requirements hereinbefore set forth in this
Section. A copy of such instructions shall be forwarded by the Company, to the
Issuer.

                 Upon the redemption date contemplated by this Section,
provided there has been deposited with the Trustee the total amount as
required, such amount shall constitute the total compensation due the Issuer
and the holders of the Bonds as a result of an occurrence of such Determination
of Taxability and the Company shall not be deemed to be in default hereunder by
reason of the occurrence of such Determination of Taxability.

                 Upon the occurrence of a Determination of Taxability, any
other option of the Company to prepay the rents required to be made under
Section 5.2 shall be superseded by its prepayment of

Mr. Jim Loree
Zantop International Airlines, Inc.
Ypsilanti, Michigan

Dear Jim:

     Enclosed is a history and description of the Zantop facilities and
operations in Macon.  I have attempted to boil down all of the many details of
the arrangements between Zantop, the City and the Authority into a fairly short
summary.  I think the attachment of the 1986 lease agreement and the project
summary of the 1992 expansion may be particularly helpful.

     Also, I have not, of course, been able to color the plats which I have
attached, but I hope you can color as suggested in the summary.  Also, please
enter the amount of the unpaid principal on each bond issue.

     Jim, I suspect as this project moves forward, that we will need to have a
meeting with the other parties and go through all of the documents so that
everyone will have a full understanding.  I suspect that this might be best
done in Macon, and it will probably take some time to go through all of the
documents.  If you think this would be the proper approach, and if we can help
with this, please let us know.

     Please look at the attached carefully.  In my haste to get this to you
this afternoon, I may have misstated something or left something out that may
be considered crucial.  If you have any revisions to suggest, please call me or

                HISTORY AND DESCRIPTION OF ZANTOP INTERNATIONAL
                AIRLINES, INC. FACILITIES AND OPERATIONS AT THE
                MIDDLE GEORGIA REGIONAL AIRPORT, MACON, GEORGIA


     Zantop International Airlines, Inc. ("Zantop") initiated its operations at
the Middle Georgia Regional Airport ("Airport") under a lease assignment
agreement dated September 2, 1980, with the Macon-Bibb County Industrial
Authority ("Authority") and Hawaiian Airlines, Inc. ("Hawaiian").  The original
site of operations consisted of an aircraft repair and maintenance center which
had been constructed on the original site for use by and lease to Hawaiian.
Hawaiian was not successful in an air freight operation which it undertook, and
Zantop agreed, by the September 2, 1980, lease agreement, to assume the
responsibilities and rights of Hawaiian under its agreements with the City of
Macon ("City") and the Authority.

     The property covered by the September 2, 1980, agreement consisted of the
property shown as Parcel 1 on Exhibit "A," which is attached hereto.  For
convenience, this Parcel 1 is shaded in red on Exhibit "A."  This Parcel 1 is
owned by the City, but was leased by the City to the Authority on September 2,
1979, for use by the Authority for sublease to Hawaiian.

     The sublease between the Authority and Zantop was amended on two
occasions: October 4, 1982, and September 12, 1983.

     On September 13, 1985, the City leased an additional parcel of land to
Zantop.  This parcel is adjacent to Parcel 1 referred to above, and is shown as
Parcel 2 (consisting of an apron area of 99,068 square feet and a ground lease
area of 100,932 square feet, as well as Parcels "A," "B," and "C," on Exhibit 
"A" 
<PAGE>   77
attached hereto.  All of the properties subject to lease under the September 13,
1985, lease are shown in blue on Exhibit "A" attached hereto.
     
     On December 19, 1986, the City and Zantop executed an agreement which
merged all previous lease agreements into one comprehensive agreement.  A copy
of this lease agreement is attached hereto.  The 1986 lease permitted an
expansion of the Zantop facilities, and Zantop built a new hanger on a
reconfigured Parcel 2, consisting of approximately 47,000 square feet, said
hangar is located on Parcel 2 as indicated on Exhibit "B." 

     The 1986 expansion was financed by the issuance of revenue bonds by the
Authority in the amount of $3,950,000.00. These bonds are paid through lease
payments made by Zantop. Final payment will occur in 1998.  The current
principal balance due on these bonds is $ 675,000.00 as of June 1, 1997.

     In 1993, Zantop needed additional space and entered and entered into
agreements with the City and the Authority which permitted the Authority to
issue additional revenue bonds in the amount of $4,500,000.00.  With these
funds, Zantop constructed a new hangar consisting of approximately 68,500 square
feet on Parcels 1 and 2A, as shown on Exhibit "B" (said new hangar being
attached to existing buildings).  Under the 1993 agreement, Zantop agreed to pay
additional rentals sufficient to pay debt service on the bonds through May 1,
2018.

     The principal balance due on these bonds is $ 4,190,000.00 as of May 1,
1997.

     For a better understanding of the 1993 agreements, a "Project



                                       2

<PAGE>   78
Memorandum" is attached hereto.

     This project memorandum was approved by Zantop, the City and the
Authority, and the expansion and financing activities as described in the
memorandum were essentially carried out as planned.

     The foregoing information is, indeed, a summary.  Many details are not
stated, but all pertinent documents are available for review.

     This summary is intended to be a guide to an understanding of the status
of Zantop facilities and operations at Macon vis a vis the City and the
Authority.

Dear Jim,

According to your lease with the City of Macon dated December 1986, the rental
payment for parcels 1 and 2A is $2,473.00. This rate began on 8/01/93 and runs
to 8/01/96.

A Cost of Living increase should have been adjusted to your monthly invoice
as of August 1996, but was inadvertently overlooked.

The adjustment should have been done by the formula as follows:


                  August, 1996 CPI-W               154.5
Rent on 8/01/86 x ------------------ = $2,473.00 x ----- = $2,683.14
                  August, 1993 CPI-W               142.4

                               PROJECT MEMORANDUM
               ZANTOP INTERNATIONAL AIRLINES, INC. 1992 EXPANSION

     Zantop International Airlines, Inc. ("Zantop") has operated an aircraft
maintenance, overhaul and repair facility at Middle Georgia Regional Airport
since 1980. Zantop now employs approximately 335 people in skilled and
managerial positions. Exhibit "A" attached hereto is a Historical and
Statistical Highlights summary of Zantop operations. Exhibit "B" attached hereto
(letter from Zantop to Tom Moody) sets forth some details of Zantop expansion
plans.

     Zantop has proposed to substantially increase its operations and its
employment at the airport if satisfactory facilities can be provided.

     This memorandum outlines the general details of a proposed transaction
which will permit expansion of facilities and operations of Zantop. It is
understood by the parties that if the general plan as outlined herein is
approved by Zantop, the City of Macon, County of Bibb and the Macon-Bibb County
Industrial Authority ("Authority"), the project will be undertaken and the
necessary documentation will be put in place to consummate the transactions
involved.

     The following definitions shall apply throughout this Project Memorandum.

                                  EXHIBIT "A"
<PAGE>   89
     (a)  "Hangar I" means the original hangar built for Hawaiian Airlines
owned by the City and leased by Zantop and shown outlined in red on Exhibit "C";

     (b)  "Hangar II" means the hangar constructed in the 1986-87 period now in
use by Zantop and shown outlined in green on Exhibit "C";

     (c)  "Hangar I Additions" means the additions to be made to Hangar I and
support facilities (including fixed permanent equipment) to be constructed and
acquired, said additions shown outlined in blue on Exhibit "C";

     (d)  "Hangar III" means Hangar I, together with Hanger I Additions (red
and blue on Exhibit "C");

     (e)  "Zantop Series 1992 Bonds" means the bonds described in paragraph 4
hereunder.

     1.   New Facilities. Hangar I Additions, consisting of approximately
61,500 square feet will be constructed on the airport ramp adjacent to and
connected with Hangar I so as to constitute Hangar III. A plat generally
outlining the existing areas under lease by Zantop and depicting the location of
Hangar I improvements is attached as Exhibit "C". The cost of the new facilities
is estimated to be approximately $4,000,000, but in any event, no more than
$4,500,000 ("Project Costs").

     2.   Site Improvements. In order to accommodate the Zantop expansion,
substantial improvements need to be made to airport properties, including
improvements of portions of ramp space located upon Parcels 1 and 2 as

                                     - 2 -
<PAGE>   90
shown on Exhibit "C" and upon ramp space adjacent thereto, vehicular parking
expansion and improvements, storm water drainage improvements, augmentation of
the existing fire protection water supply and other miscellaneous improvements.
The scope of these improvements and the estimated costs thereof will be
determined by the parties on an expedited basis. A preliminary list of
improvements is attached as Exhibit "D" hereto. An analysis of the improvements
indicates that some of the items are quite directly related to the Zantop
project, and others are indirectly related to the project, but nevertheless
necessary to approximately and conveniently accommodate Zantop's expansion as
well as for the improvement for the infrastructure of the City's airport. The
Authority shall pay the costs for Items shown on Exhibit "D".

     3.   Financing. Project Costs will be financed through a lease arrangement
between the City, Industrial Authority and Zantop. The term "Project Costs" as
used in this memorandum shall include the actual cost of the Hangar I Additions,
the cost for site improvements as described in Exhibit "D", capitalized
interest on the bonds during the construction period minus estimated
construction fund earnings and two percent of the bond amount for issuance costs
as allowed under current federal law. The Macon-Bibb County Industrial Authority
will issue revenue bonds in an amount not to exceed $4,500,000 for the cost as
described above. Zantop will enter into a twenty-five


                                     - 3 -
<PAGE>   91
year lease of Hangar III (the "1992 Lease") and lease payments shall be
sufficient under the term of the lease to retire all debt service on the bonds
to be issued for Project costs (the "Basic Fixed Rental"), as well as $2,473.00
per month commencing on August 1, 1993 (allocated as rent for Parcel 1 charged
by the City (the "Additional Rent"). Zantop shall also pay to City the sum of
$10,000 per year as a payment for City services on Hangar I Additions, in
addition to other rental payments, said payments to commence on November 1,
1993, and continue through the term of the 1992 Lease. Further, Zantop shall
make payments for City services as required by Paragraph 5(A) of the lease
agreement between the parties dated December 19, 1986 (the "1986 Lease"), and
these payments shall continue through the term of the 1992 Lease. Further, the
$10,000 per year payment described above shall be adjusted each four (4) years
commencing on November 1, 1997, in accordance with the CPI adjustment formula
set forth in Paragraph 5(A) of the 1986 Lease: provided however that in no event
shall said payment ever be less than $10,000. In consideration for Zantop's
inclusion of site improvements in the Project Cost and their payment of excess
issuance costs over and above amounts that can be financed with proceeds of the
tax exempt bonds, such cost to be in excess of $200,000.00, the City agrees that
for a period of twenty years, beginning on November 1, 1993, Zantop will be
credited $10,000


                                     - 4 -
<PAGE>   92
annually against amounts owed to the City for City services on Hangar I
additions. Additionally, Zantop agrees to grant and convey to the City a
security interest in its leasehold interest and all improvements located on
Parcels 2, A, B and C. Prior to August 1, 1993, rents shall continue as
presently required by the 1986 Lease, and Additional Rent payments shall be
adjusted every four (4) years. The debt service on the bonds will be guaranteed
by the City, but the lease payments by Zantop shall be sufficient for a period
of twenty-five years so as to cover all debt service, payments for City services
and Additional Rent. Furthermore, the parties agree that in the event the City
allows Zantop to construct additional improvements in the future on the leased
premises at Zantop's sole expense and without any financing to be guaranteed by
the City, in any way, then the City will not require an additional payment for
City services regarding the proposed future improvements.

     4.   Contract for construction of Hangar I Additions. The Authority shall
contract with Zantop to construct the Hangar I Additions. Plans and
specifications shall have prior approval of the City. Construction costs shall
be paid from bond proceeds. 

     5.   Terms of the Lease. Based upon a $4,500,000 Zantop Series 1992 Bond
issue, the Basic Fixed Rental to be paid by Zantop over a 25 year period will be
approximately $372,000 per year assuming a 6.6% average


                                      - 5 -
<PAGE>   93
interest rate. This rental will pay all debt service on the Series A Bonds. The
actual Basic Fixed Rental will be determined by the interest rate at the time
the bonds are sold.

     Except for the ramps and taxiways located on the Leased Premises, Lessee
shall, at its own expense, maintain the leased premises during the term of this
Lease and any renewal or extension thereof in presentable condition and, in
doing so, shall keep the premises in a presentable, safe and neat condition.

     Lessor shall not be required to make any repairs or improvements to said
leased premises (excluding ramps and taxiways) during the term of this Lease, or
any renewal or extension hereof. It is agreed that Lessee shall have the right
to make such improvements to the leased premises as may be agreed in writing
between the parties, and it is further agreed that any building or permanent
improvements erected or constructed on said premises shall, upon construction or
erection, become part of the realty and become the property of Lessor, subject
to the Lessee's right of use and occupancy during the term of this Lease or any
extensions thereof.

     Lessor, in its reasonable discretion, shall be the sole judge of the
quality of maintenance of the leased premises by Lessee. Upon written notice by
Lessor, through its Airport Director, the Lessee shall be required to perform
whatever reasonable maintenance Lessor may deem


                                     - 6 -

          Although Zantop International Airlines, Inc., was organized on May
30, 1972, its history goes back to 1946, shortly after World War II, when Duane
Zantop, sole stockholder of the present company, and his brothers organized
Jackson Flying Service. Shortly thereafter they formed an airline known as
Zantop Air Transport and moved their operation to Detroit's Metro Airport from
where they moved freight and passengers under a Supplemental Air Carrier
Certificate. In 1966, Zantop Air Transport, by then the world's largest
Supplemental Air Carrier, was sold to a New York based group of investors. This
company changed its name and operated out of Willow Run Airport and Oakland,
California, until its demise in April of 1972.

          To fill the need of local industry, especially the automotive
companies, Zantop International Airlines was formed with an original capital
cash investment of $50,000, a lot of talent, and many cooperative suppliers. It
is the only scheduled airline with its corporate offices in Michigan and the
only one operating an air cargo hub in the state.

          Zantop International Airlines provides all-cargo scheduled and
charter service within the USA and charter service internationally from its
base at Detroit's Willow Run Airport. In May 1978, the company received
authority to provide general cargo service and, by 1980, expanded into a
scheduled hub system at Willow Run Airport serving 19 of its own air freight
stations throughout the USA.

          Zantop maintains FAA-approved repair stations at both Willow Run
Airport and at its maintenance facility at the Macon Municipal

Mr. Tom Moody, Executive Director
Macon-Bibb Co. Industrial Authority
305 Colesium Drive
Macon, GA 31202

Dear Tom:

     Zantop International Airlines moved into the Macon Airport facility during
the fall of 1980. Attracting us to the area was a hangar facility capable of
housing the L-188 electra aircraft which is the predominant type in Zantop's
fleet. Other factors included generally mild climate, a good recruit area for
aircraft mechanics, and a very congenial city and county government. Throughout
the years Zantop's needs have changed and we have progressed into a premier
third party maintenance provider. Major milestones for this facility include the
following:

     1.  1982  Began providing contract third party maintenance service.

     2.  1985  Received FAA Repair Station Certification.

     3.  1985  Acquired supplemental type certificate (STC) allowing Zantop to
               convert DC-8 passenger aircraft to all cargo configuration.

     4.  1985  Completed first DC-8 modified cargo aircraft 25 aircraft 
         completed to date.

     5.  1985  Entered into agreement to build new 40,000 square ft. hangar.

     6.  1986  Developed all data and received STC for L-188 flight director
               installation.     

     7.  1987  Established a formal training department.

     8.  1988  Completed construction of new 40,000 square ft. hangar facility.

     The facility has grown from approximately 65 employees in 1980 to 335 at
the present time. Temporary employees used during 1990 and 1991 boosted
employment to over 500. Annual payroll has increased to $7,800,000.00 and
local vendor (Middle Georgia) orders surpass $1,600,000.00 annually.



                                   EXHIBIT B
<PAGE>   100
     Zantop has steadily increased the Macon sales in spite of a turbulent and
difficult economic environment. These sales are almost entirely to non-Georgia
companies and include work on European aircraft. Zantop's total Macon sales in
1991 was $14.4 million and it should be noted that most economist have found a
spending multiplier of about six (6) for facilities such as Zantop so that each
dollar spent in the Macon area will have about a six dollar impact on merchants
in the area.

     During the last two years the FAA has mandated and operators are now
requiring that an aircraft which is having large amounts of maintenance
performed on it be placed into a suitable hangar facility. Since we are
primarily involved in DC-8 type aircraft, a need for more space to hangar these
aircraft has arrived. In order for Zantop to expand our customer base and also
receive a larger portion of our existing customer's work we must expand the
present facility. When completed an additional 140 employees would be required
to man load one line of aircraft. The majority of these employees would be
aircraft sheetmetal and could be hired from the local technical schools.

     I have been working with Chris Sheridan to develop some preliminary plans
as to what Zantop's needs are. We feel the plans are acceptable and now are at
the point in which you need to be involved since the city owns the hangar that
will be enlarged.

     Would you please develop some ideas on various ways we could proceed with
this project. Jim Zantop will be in town on September 14 and we will meet in
your conference room on September 15, 1992.

     We look forward to working with you on this project and hopefully we will
have another hangar by this time next year.


Best regards,


Timothy J. [ILLEGIBLE]
Manager of Maintenance

       ______SUME OF WATER AVAILABLE FOR FIRE PROTECTION NEEDS TO BE           ESTIMATED 
       _____EASED IN ORDER TO MEET CODE REQUIREMENTS FOR THE NEW HANGAR.         COSTS
       IT IS PROPOSED TO MEET THIS REQUIREMENT BY PROVIDING A MEANS TO 
       REFILL THE RESERVOIR DURING A FIRE RATHER THAN INCREASING THE SIZE 
       OF THE RESERVOIR. ALSO, THE SIZE OF THE NEW HANGAR WILL REQUIRE 
       ADDITIONAL PUMPING CAPACITY IN THE AIRPORT'S EAST RAMP, FIRE 
       PROTECTION PUMPING STATION.                                              ($ 30,000.00)

II.    RAMP EXTENSION

       THE DEPTH OF THE RAMP NEEDS EXTENDED TOWARD THE TAXIWAY TO PROVIDE
       AN ADEQUATE MANEUVERING AREA IN FRONT OF THE HANGARS. FORTUNATELY
       THE GRASSED AREA BETWEEN THE RAMP AND TAXIWAY "CHARLIE" IS ACTUALLY
       PAVED -- THE PAVEMENT DATES BACK TO WORLD WAR II. RATHER THAN HAVING 
       TO CONSTRUCT AN EXPENSIVE, FULL DEPTH PAVEMENT, IT IS ANTICIPATED THAT
       THE AREA WILL ONLY NEED AN ASPHALT WEARING SURFACE PAVED OVER THE
       ORIGINAL WORLD WAR II PAVEMENT.                                          ($ 46,000.00)

III.   PARKING

       ADDING TWO HANGAR BAYS WHICH WILL ACCOMMODATE DC-8'S WILL ADD
       APPROXIMATELY 250 EMPLOYEES TO ZANTOP'S PAYROLL. ADDITIONAL PAVED 
       PARKING AND THE PAVING OF EXISTING, STONE SURFACED PARKING LOTS IS 
       NEEDED.                                                                  ($ 37,000.00)

IV.    RAMP AT FRONT OF NEW HANGAR.

       THE GRADE OF THE EXISTING RAMP AT THE FRONT OF THE NEW HANGAR WILL
       NEED TO BE INCREASED IN ORDER TO MEET CODE REQUIREMENTS FOR DRAINAGE
       AWAY FROM THE HANGAR. THIS CAN BE ACCOMPLISHED BY PAVING A TAPERED
       WEARING SURFACE ON TOP OF THE EXISTING RAMP. THE MAXIMUM DEPTH OF THE
       NEW ASPHALT AT THE HANGAR WILL BE 3 INCHES AND IT WILL TAPER TO THE
       EXISTING RAMP SURFACE FIFTY FEET OUT IN FRONT OF THE NEW HANGAR.         ($ 11,000.00)

V.     REPAIR OF SOFT AREAS IN PAVEMENT OF RAMP

       THERE ARE SEVERAL DETERIORATED AREAS IN THE PAVEMENT OF THE EXISTING
       RAMP WHICH NEED ATTENTION. THE OTHER PAVING REQUIRED FOR THE PROJECT
       PRESENTS AN ECONOMICAL OPPORTUNITY TO MAKE THESE NEEDED REPAIRS. THE
       DETERIORATED AREAS IN THE RAMP ARE PRESENTLY HAVING TO BE COVERED BY
       STEEL PLATE IN ORDER TO PREVENT DAMAGE TO AIRCRAFT LANDING GEAR.         ($ 15,000.00)
                                                                                ------------
                                                 ESTIMATED TOTAL                ($139,000.00)

         three years, commencing on September 1, 1988, as follows:

               The rental of $1649.98 per month shall be increased by the same
               percentage by which the cost of living has increased, if any,
               from the beginning of this Lease to the beginning of the three
               year period for which each rent adjustment is computed, based
               upon the increase, if any, in "all items," Consumer Price
               Index for Urban Wage Earners and Clerical Workers, U.S. City
               Average: All Items (1967 = 100), published by the United States
               Bureau of Labor Statistics (Index). The adjusted monthly rental
               so computed shall continue through each three year period for
               which each computation of rent adjustment shall have been made.
               In no event shall the monthly rental be less than $1649.98.

               4.  Additional Rent if Aircraft Fuel is Not Purchased From A City
         Lessee. In the event that Zantop should not purchase all of its Macon
         uplift aircraft fuel requirements from a vendor which, at the time of
         purchase, is a direct or indirect lessee of the City, then, and in that
         event, Zantop shall pay to the City




                                     - 3 -
<PAGE>   107
as additional rent One Cent ($.01) on each gallon of aircraft fuel purchased
from a vendor who is not then a direct or indirect lessee from the City. Lessees
from the City who sell aircraft fuel at the Airport are required to pay to the
City as rental One Cent ($.01) per gallon as part of the consideration for their
leases, and the purpose of this paragraph of the Agreement is to assure that the
City will not lose this revenue should Zantop purchase aircraft fuel from a
vendor which is not a direct or indirect lessee from the City. Nothing contained
in this Lease shall prevent Zantop from purchasing from a vendor of its choice.

         The term "Macon uplift aircraft fuel" means the fuel that is loaded
into Zantop's aircraft tanks at the Airport.

         5.   Payment in lieu of taxes.

         A.   Zantop agrees to make a payment in lieu of taxes to the City for
the existing hangar facility located on Parcel "1", Exhibit "B", on November 1,
1994, and on that date each year thereafter for the balance of the Lease
Agreement and all option periods which are exercised by Zantop. Said payment in
lieu of taxes shall be in addition to the rental payments provided for in this
lease. Said payment in lieu of taxes shall be figured as follows:

     Gross Value of Hangar on January 1, 1994     = $1,500,000
     x 82% (Current estimated Value Ratio
            for Industrial Facilities)            = $1,230,000
     x 40% Net Taxable Value                      = $  492,000
     x the mileage rate levied by the City of Macon
     in the year 1994 and in each year thereafter.

         The Gross Value will be fixed for a period of five years. Commencing
on November 1, 1999 and every five years thereafter the Gross Value shall be
increased by the same percentage by which the cost of living has increased, if
any, from January 1, 1994 to the beginning of the five year period for which
each payment in lieu of taxes adjustment is computed, based upon the increase,
if any, "all items," Consumer Price Index for Urban Wage Earners and Clerical
Workers, U.S. City average: all items (1967 = 100) published by the United
States Bureau of Labor


                                      -4-
<PAGE>   108


Statistics (Index). The adjusted payment in lieu of taxes so computed shall
continue through each five year period for which each computation of said
payment in lieu of taxes adjustment shall have been made. In no event shall the
Gross Value be less than $1,500,000.

         B.   Zantop agrees to make a payment in lieu of taxes to the City for
the new hangar facility located approximately as shown on the attached Exhibit
"B" on November 1, 1988, and on that date each year thereafter for the balance
of the Lease term and all option periods which are exercised by Zantop. Said
payment in lieu of taxes shall be in addition to the rental payments provided
for in this lease. Said payment in lieu of taxes shall be figured as follows:

     Gross Value of Hangar on January 1, 1988     = $3,000,000
     x 82% (Current estimated Value Ratio
            for Industrial Facilities)            = $2,460,000
     x 40% Net Taxable Value                      = $  984,000
     x the mileage rate levied by the City of
     Macon in 1988 and in each year thereafter.

         The Gross Value will be fixed for a period of five years. Commencing on
January 1, 1993 and every five years thereafter, the Gross Value shall be
increased by the same percentage by which the cost of living has increased, if
any, from January 1, 1988 to the beginning of the five year period for which
each payment in lieu of taxes adjustment is computed, based upon the increase,
if any, in "all items" Consumer Price Index for Urban Wage Earners and Clerical
Workers, U.S. City Average: all items (1967 = 100), published by the United
States Bureau of Labor Statistics (Index). The adjusted payment in lieu of taxes
so computed shall continue through each five year period for which each
computation of the payment in lieu of taxes adjustment shall have been made. In
no event shall the Gross Value be less than $3,000,000.

         C.   Zantop agrees that in the event any improvements (other than
routine repairs and maintenance) are made to any of the hangar facilities
located on the leased premises, or if new



                                      -5-
<PAGE>   109


facilities are constructed, that it will report the costs of said improvements
or new facilities and the same formula outlined above would then be applied to
the improvements so as to increase the payments in lieu of taxes
proportionately.

         6.   Option.  Zantop shall have the option of extending the term of the
lease of the same terms and conditions for two renewal terms of ten years each.
Said option shall be exercisable as follows:


         Not more than one year nor less than six months prior to the expiration
of the original term, Zantop shall, if it desires to exercise these options,
notify the City in writing of its election to exercise a renewal option. Should
Zantop fail to do so within such time, its right to exercise shall nevertheless
be extended until thirty days after the City notifies Zantop in writing that it
has not received a notice of exercise from Zantop.

7.   Construction of New Hangar Facility. Zantop agrees to construct a new
hangar and shop facility on the site shown as the "proposed hangar" on the
attached Exhibit "B" entirely at Zantop's expense. The City will not be called
upon to assume nor guarantee any debt in connection with the costs of this new
hangar which is estimated to be $3,000,000. Zantop further agrees that
construction must commence on said new facility on or before June 30, 1987.
Once construction has commenced, Zantop agrees to prosecute the same with due
diligence to completion of the facility. For the purposes hereof, construction
will be deemed to have commenced upon the accomplishment of the following, with
evidence thereof to the City: (a) Zantop and its general contractor shall have
entered into a contract for the construction of said facility, and (b) the
general contractor shall have begun the performance of such contract, including
at the minimum the commencement of rough grading activities and the excavation
of footings and foundations. The City at its sole option may extend the date by
which construction must commence, however, said date shall not be extended to a
date any later than September 30, 1987.

         8.   Use. The Leased Premises are primarily to be used for air cargo
operations, the maintenance, overhaul, modification and repair of aircraft, and
for office and administrative functions related thereto, and may be used for any
other lawful purpose or purposes which are not in conflict with the normal
operations of the Airport. Zantop is specifically granted the right to
construct, operate and maintain one or more aircraft hangars, shops, office
facilities and any and all other improvements necessary to carry out Zantop's
operations at the Airport, provided that the construction of such facilities
shall be in accordance with all reasonable policies and guidelines of the City
and the Federal Aviation Administration. Zantop shall, at its own expense,
repair all damages to the premises caused by its employees, patrons, or its
operation thereon, and shall maintain and repair all equipment thereon,
including any drainage installations, paving, curbs, islands, buildings, and
improvements.

         The City shall not be required to make any repairs or improvements to
said leased premises during the term of this Lease, or any renewal or extension
hereof. It is agreed that Zantop shall have the right to make the improvements
referred to above and such other improvements to the Leased Premises as may be
agreed in writing between the parties. It is further agreed and provided that
no mobile or portable building or trailer, placed upon the Leased Premises,
shall at any time be used for living or sleeping quarters and shall be used only
in connection with the operation of the business of Zantop, hereinbefore
specified.

         The City, in its reasonable discretion, shall be the sole judge of the
quality of maintenance of the Leased Premises by Zantop. Upon written notice by
the City, through its Airport Director, to Zantop, Zantop shall be required to
perform whatever reasonable maintenance City may deem necessary. If said
maintenance is not undertaken by Zantop within ten (10) days after receipt of
written notice, the City shall have the right to 



                                      -7-

<PAGE>   111


enter upon the Leased Premises and perform the necessary maintenance, Zantop
being liable for the cost thereof.

         Upon the termination of this Lease, Zantop shall return the premises
and any such improvements to City in good condition, reasonable wear and tear
and uninsured casualty damage excepted, and such improvements shall become the
property of City. Zantop shall maintain such facilities constructed by Zantop in
good condition and the City shall have no responsibility or liability for the
construction or maintenance of said facilities.

         9.   Responsibility of the City to Maintain Aircraft Aprons.
Notwithstanding the provisions of the preceding paragraph, the City agrees to
maintain the apron lease areas, consisting of a total of 294,500 square feet as
shown on Exhibit "B" in good and serviceable condition.

         10.  Liability of City.  It is agreed that the City shall not be
responsible or liable for the loss of or damage or injury to persons occurring
on or about the Leased Premises. Zantop shall at all times keep the premises in
a safe condition for its invitees and licensees. Zantop agrees to indemnify,
hold City harmless and defend City in respect of damage or injury to City, the
Leased Premises and the property or persons of City's other tenants, or anyone
else, on or about the Leased Premises.

         11.  Subletting. Zantop may sublet all or any portion of the Leased
Premises, provided, however, that it shall first obtain the written consent of
the City, which consent shall not be unreasonably, arbitrarily or capriciously
withheld.

         12.  Other Agreements.  Zantop shall not enter into any transaction
which would deprive City of any of the rights and powers necessary to perform
all covenants or other obligations under various type agreements with the United
States of America relating to the use of Airport property.

         13.  Removal of Equipment.  Zantop may (if not in default hereunder) at
any time prior to the termination of this Lease, or any extension hereof, remove
all fixtures and equipment which it has placed on the Leased Premises or in any
improvements



                                      -8-
<PAGE>   112


erected thereon, provided that Zantop shall repair all damages to the premises
caused by such removal.

         14.  Assignment.  The City recognizes that it shall be necessary for
Zantop to assign all its rights under this lease as security and collateral for
the project funds required for the improvements to be made upon the leased
premises and the City consents and agrees to such assignment or assignment for
such purposes; provided that any entity which obtains ownership of such rights
or obtains possession of the leased premises because of a default on the part of
Zantop in connection with the financing arrangements for said improvements shall
only have such rights as provided to Zantop by this lease and any such entity
shall be entitled to exercise such rights upon the continuing acceptance of the
obligations of Zantop imposed by this lease.

         15.  Default.  It is mutually agreed that in the event Zantop should
default in the payment of rent, when due, or any other default occurs as to the
performance of other terms and provisions of this Lease, and Zantop fails to
cure any such default within ninety (90) days after the date of receipt of
written notice of default from the City, or if Zantop should be adjudicated a
bankrupt; then, in any event, the City may terminate this Lease: provided,
however, that upon such default occurring the City shall also notify IDBI
Managers, Inc., as managing general agent for Firemen's Insurance Company of
Newark, New Jersey (the "Agency"). Such notice to the Agency shall be
simultaneous with the notice given to Zantop, and after such notice of default
to Zantop and the Agency, the Agency may, pursuant to the financing agreements
between Zantop and the Agency, assume lease payments or other obligations
required by this Lease so as to cure such default.  Upon such termination of
this Lease by the City, Zantop will at once surrender possession of the Leased
Premises to the City and will remove all of Zantop's property therefrom. The
City may forthwith re-enter the Leased Premises and take possession thereof, and
it may remove all persons and effects therefrom, using such force as may be



                                      -9-
<PAGE>   113

reasonably necessary without being guilty of trespass, forceful entry, detainer
or other tort.

         16.  Reasonable Access.  The City shall at all times provide Zantop
with reasonable access to the Leased Premises by vehicles, aircraft, and
pedestrians. Zantop agrees that the City shall have reasonable access over and
upon the Leased Premises for inspection, security emergencies or other purposes
which do not unreasonably interfere with the use of the Leased Premises by
Zantop.

         17.  Signs.  Zantop shall place no signs upon the outside walls or roof
of the Leased Premises, except with the written consent of the City, which
consent shall not be unreasonably, arbitrarily or capriciously withheld.

         18.  Attorney's Fees.  If any rent owing under the terms of this Lease
is collected by or through an attorney at law, Zantop agrees to pay an
additional fifteen percent (15%) thereof as attorney's fees.  

         19.  Strict Compliance.  Time is of the essence of this contract. All
rights conferred upon the City to enforce this Lease are cumulative of those
conferred by law. The waiver of any provision hereunder by the City shall not
constitute a waiver of its rights to demand exact compliance with all terms
hereof.

         20.  Peaceable Enjoyment.  The City agrees that upon payment of the
rent herein provided for, and upon observance and performance by Zantop of the
covenants herein contained and on the part of Zantop to be observed and
performed. Zantop shall peaceably hold and enjoy the Leased Premises for the

same.

         23. Force Majeure. For the purpose of any of the provisions of this
Agreement, neither City nor Zantop, as the case may be, nor any successor in
interest, shall be considered in breach of, or default in, the obligations
thereof with respect to this Agreement in the event of enforced delay in the
performance of such obligations due to unforeseeable causes beyond the control
and without the fault or negligence thereof, including, but not restricted to,
acts of God, acts of the public enemy, acts of the Federal Government, acts of
the other party, fires, floods, epidemics, quarantine restrictions, strikes,

pension liabilities thereunder; and no "reportable event" within the meaning of
Section 4043 of ERISA (other than the proper termination of such plans referred
to above) has occurred with respect to any such plan.

     6.10 Remediation of Real Property

          (a) Buyer and Seller agree that a Phase I Environmental Site
Assessment of the Real Property has indicated the possible existence of
recognized environmental conditions at the Real Property. Promptly after the
Closing, Seller will conduct and complete, at its sole cost and expense, such
additional environmental investigations, studies, sampling and testing
(collectively, the "Investigation") as may be required in order to more
accurately determine the existence and extent of any recognized environmental
conditions identified in the Phase I Environmental Site Assessment. Upon
completion of the Investigation, and unless Seller has and exercises the option
to purchase the Real Property pursuant to Section 6.10(b), Seller shall, at its
sole cost and expense, and as expeditiously as possible, remedy all recognized
environmental conditions identified by the Investigation to the full extent
necessary to bring the Real Property into compliance with all applicable
federal, state and local environmental laws, regulations, ordinances and other
governmental requirements ("Environmental Laws") and in no case requiring a deed
restriction on the use of the Real Property (the "Remediation"). Buyer shall
have full access to all information pertaining to the Investigation and the
Remediation, all of which will be conducted so as to interfere as little as
possible with the ongoing operation of the Business.

          (b) Seller shall have the right and option, in its sole discretion, to
purchase the Real Property, upon the terms and conditions hereinafter set forth,
in lieu of undertaking the remediation. Such option is exercisable by giving

of five (5) years after the consummation of this transaction in any capacity
whatsoever (either as an employee, officer, director, stockholder, proprietor,
partner in a joint venture, consultant, or otherwise) engage in any business
competitive with the Business as conducted by Crystek at the time of this
Agreement, or solicit from any firm, person, or corporation which shall be
either a customer or supplier of Crystek any such business or purchase for
resale any such equipment, inventory, or supplies that would be competitive with

as a matter of law and hereby consents to injunctive relief within the
jurisdictional parameters set forth in this Agreement.

(including, without limitation, reasonable attorneys' and accountants' fees and
disbursements) whatsoever arising out of or resulting from (i) any breach of
warranty or misrepresentation made in this Agreement by Seller, or in any
exhibit, schedule or certification furnished pursuant hereto, or the

Agreement, the Indemnitor hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts and hereby waives any right it may have to object to the bringing of any

                                FIRST AMENDMENT
                                       TO
                            STOCK PURCHASE AGREEMENT

     THIS FIRST AMENDMENT TO STOCK PURCHASE AGREEMENT ("First Amendment") is
made as of the 31st day of March, 1997, by and among CRYSTEK ACQUISITION
CORPORATION, a Florida corporation ("Buyer"), WHITEHALL CORPORATION, a Delaware
corporation ("Seller"), and CRYSTEK REAL ESTATE CORPORATION, a Pennsylvania
corporation (the "Land Company").

                                  WITNESSETH:

     WHEREAS, Seller and Buyer have previously entered into a Stock Purchase
Agreement dated February 13, 1997 (the "Purchase Agreement") pursuant to which
Seller has agreed to sell, and Buyer has agreed to purchase, all of the
outstanding shares of capital stock of Crystek Crystals Corporation, a Florida
corporation ("Crystek"); and

     WHEREAS, Seller currently owns certain Real Property (as defined in the
Purchase Agreement) which Seller intended to convey to Crystek on or before the
Closing Date; and

     WHEREAS, Seller and Buyer have made certain agreements under the Purchase
Agreement with respect to the Real Property, the remediation of certain
environmental conditions which may exist with respect to the Real Property, and
the possible reconveyance of the Real Property to the Seller, all as more
fully described in the Purchase Agreement; and

     WHEREAS, in order to facilitate the Buyer's financing of the transactions
contemplated by the Purchase Agreement, the parties now wish to amend their
agreement to provide (i) that the Real Property shall be purchased by the Land
Company, rather than conveyed by Whitehall to Crystek, and (ii) that a portion
of the purchase price payable under the Purchase Agreement shall be added to
the Buyer's Promissory Note deliverable at Closing, and deducted from the cash
payable at Closing, all as more fully described herein. 
<PAGE>   2
     NOW THEREFORE, the parties hereto, intending to be legally bound, hereby
agree as follows:

          1.  Definitions. Except as otherwise defined herein, all capitalized
terms used in this First Amendment shall have the meanings assigned to such
terms in the Purchase Agreement.

          2.  Purchase of Real Property.

              (a) The parties agree that, on the Closing Date, the Real
Property shall be transferred and conveyed by Seller to the Land Company, by
special warranty deed, for a purchase price of $300,000. Accordingly, the
purchase price payable for the Shares under the Purchase Agreement shall be
reduced from $2,714,310 to $2,414,310. The allocation of the purchase price set
forth in Schedule 2.08 to the Purchase Agreement shall be restated as set forth
on Schedule 2.08 attached hereto.

              (b) The cost of title insurance with respect to the conveyance of
the Real Property shall be equally divided between Seller and the Land Company,
based upon the purchase price therefor. From and after the Closing Date, all
of the rights, options and obligations of Buyer set forth in Section 6.10 of
the Purchase Agreement shall belong to and be exercised solely by the Land
Company, including, without limitation, the right of access to all information
pertaining to the Investigation and the Remediation, the right and option to
require Seller to purchase the Real Property on the terms and under the
conditions set forth in Section 6.10(b) of the Purchase Agreement, and the
right and option to lease the Real Property back from Seller in the event of a
reconveyance.

     3.  Payment of the Purchase Price. The Land Company shall pay the entire
purchase price for the Real Property to Seller pursuant to a Promissory Note in
the form of EXHIBIT A attached hereto, which will be executed by the Land
Company and delivered to Seller on the Closing Date. The Note shall bear
interest at the rate of 10% per annum, payable quarterly, and the principal
shall be due and payable in a single installment due on April 30,


                                       2

1999 or sooner as provided therein. The Note shall be secured by a pledge of all
of the Land Company's outstanding capital stock, in the form of EXHIBIT B
attached hereto. The Note shall be prepayable by the Land Company at any time,
in whole or in part, without penalty.

     4.  Modification of Payment Terms. Section 2.02(a)(i) and 2.02(a)(ii) of
the Purchase Agreement are hereby amended by reducing the cash payable at
Closing to $1,850,000 and increasing the principal amount of the Note to
$564,310, the Note to be in the form of Exhibit C attached hereto (in addition
to the Promissory Note referenced in Paragraph 3 above).

     5.  Modification of Section 4.16. Section 4.16 of the Purchase Agreement
is hereby amended by deleting from lines 5 and 6 thereof the words
"Twenty-Seven Thousand Dollars ($27,000.00)" and substituting therefor the words
"all cash on hand in excess of One Hundred Thousand Dollars ($100,000.00)".

     6.  Miscellaneous.

         (a) In all other respects, the Purchase Agreement shall remain in full
force and effect, as amended by this First Amendment.

         (b) This First Amendment shall be governed by and construed in
accordance with the laws of the State of Texas.

         (c) This First Amendment shall be binding upon and inure to the
benefit of the parties hereto, as well as their respective successors and
assigns.

         (d) This First Amendment may be executed in more than one counterpart,
each of which shall constitute an original, but all of which when taken
together shall constitute one and the same document.

     IN WITNESS WHEREOF, the parties hereto have executed this First Amendment
as of
