                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL

American Aircarriers Support, Incorporated ("AAS") is an international supplier
of aviation services, which include sales of aircraft components and spare
parts, maintenance, overhaul and repair of those products, and engine
management services. Its customers include major commercial passenger and cargo
airlines, other maintenance and repair facilities and other redistributors
located throughout the world. Until the fourth quarter of 1998, substantially
all of the revenues of AAS were derived from the sale of the following
products:

     o complete Pratt & Whitney JT8D series engines and, to a lesser extent,
       General Electric CFM56 engines; 
     o engine components and spare parts primarily for these two types of
       engines; and
     o airframe components and spare parts primarily for Boeing,
       McDonnell-Douglas and Airbus aircraft. 

In the last quarter of 1998, AAS began to implement an acquisition strategy
aimed primarily at expanding its aviation capabilities with related products,
such as engine management services, maintenance, overhaul and repair services
and manufacturing capabilities, and becoming a full service "one stop" supplier
of products and services for customers. Between October 1, 1998 and November
19, 1998, AAS used three newly formed subsidiaries to acquire substantially all
of the assets, and/or the inventory, of:

     o Global Turbine Services, Inc ("GTI") and its affiliate Turbine
       Inspections, Incorporated ("TII"), an engine management service;
     o Condor Flight Spares, Inc. ("Condor"), a redistributor of landing gear
       parts and now a FAA certified landing gear maintenance, overhaul and
       repair facility;
     o American Jet Engine Services, Inc. ("Amjet"), a FAA certified
       maintenance, overhaul and repair facility specializing in jet engines;
       and
     o Global Air Spares, Inc. ("GASI") and Atlantic Airmotive Corporation
       ("AAC"), both Amjet affiliates engaged in jet engine and engine parts
       redistribution.

As a result of these transactions, AAS has expanded its service base and offers
the following additional aviation services:

     o FAA-certified engine maintenance and repair; 
     o FAA-certified landing gear maintenance and repair; and
     o Engine management services.

Operations of Amjet, Condor, GTI, TII, GASI and AAC (collectively referred to
as the "acquired companies" in this report) have continued or expanded in the
locations in which they were previously operating. Amjet, GASI and AAC now
operate as AAS-Amjet, Inc. ("AAS-Amjet"); Condor now operates as AAS Landing
Gear Services, Inc. ("AAS Landing Gear"); and GTI and TII operate as AAS Engine
Services, Inc. ("AAS Engine Services"). Unless the context otherwise required,
the term "AAS" in this report includes AAS and the acquired companies. The
principal executive office of AAS was recently relocated to 587 Greenway
Industrial Drive, Lakemont Business Park, Fort Mill, South Carolina 29715. The
phone number of the executive office is (803) 548-2160.

INDUSTRY OVERVIEW AND BUSINESS STRATEGY

Management of AAS believes that the annual worldwide market for aircraft
components and spare parts is approximately $11 billion, approximately $1.3
billion of which represents sales of aircraft components and spare parts in the
redistribution market. Management also believes that the annual worldwide
market for aircraft maintenance, overhaul and repair is approximately $27
billion. According to the 1998 BOEING REPORT, global air

                                      -2-


<PAGE>   3



travel is projected to increase approximately 63% by the year 2007, and the
number of passenger and cargo aircraft in service will increase approximately
44% to 17,700 from 12,300 in that same time period. Management expects the
aviation sales and service provider market to continue to grow due to the
number of aircraft which will be required to service the projected growth in
the passenger and cargo airline industry. To meet the demand for aircraft,
management believes operators will keep their older aircraft in operation for a
longer period of time. The 1998 BOEING REPORT estimated that two-thirds of the
12,300 aircraft, or approximately 8,200 aircraft, in use in 1997 will still be
in service twenty years later in 2017. The primary market for redistribution
sales and maintenance, overhaul and repair services is older aircraft.
Accordingly, as an increased number of older commercial aircraft are kept in
service, the demand for components and spare parts and maintenance, overhaul
and repair services to keep these aircraft in service also increases.

Management also expects that cost considerations will continue to cause
aircraft operators and maintenance, overhaul and repair facilities to purchase
components and spare parts from redistributors rather than from new parts
manufacturers. Cost considerations will also cause airlines to continue the
trends of outsourcing inventory management functions and leasing rather than
purchasing to reduce capital requirements, reducing the number of approved
suppliers, increasing the utilization of third-party service providers and
relying on just in time inventory management. Finally, management believes that
airlines prefer to use approved full service suppliers which are capable of
providing improved documentation and traceability, larger inventories, higher
standards of quality control and, most importantly, are capable of providing
"one stop shopping" for the supply of spare parts and aircraft components and
the maintenance, overhaul and repair of those parts and components. The
strategy of AAS is to enhance its position as a leading redistributor of engine
and airframe components and spare parts, to expand its maintenance, overhaul
and repair capabilities, and to integrate other aviation services in order to
provide "one stop shopping" to its customers as the aircraft industry continues
its growth.

OPERATIONS

Until the fourth quarter of 1998, the principal source of revenue for AAS has
been the sale of engines, engine components and spare parts and airframe
components and spare parts in the redistribution market. It generates these
revenues primarily from purchasing engines, engine components and spare parts
and airframe components and spare parts, having necessary repairs made by
licensed repair facilities, then selling those items from its inventory. It
also generates revenues from consignment sales and exchange transactions. Under
a typical consignment arrangement, AAS does not acquire title to the components
and spare parts, but rather remits to the title owner of the components and
spare parts being sold a percentage of the profits from the sale. An exchange
transaction generally involves a high value/high turnover rotable component or
spare part which an operator frequently replaces when performing aircraft
maintenance. In an exchange transaction, AAS delivers a component or spare part
in exchange for a "core" unit, which is the same part as the part delivered by
AAS, but in need of overhaul. The customer pays an exchange fee upon delivery.
Upon receipt of the "core" unit from the customer, AAS has the core overhauled,
bills the customer for the overhaul charges and retains the overhauled "core"
unit in its inventory for re-sale. If the "core" unit cannot be repaired, it is
returned to the customer and the exchange transaction is converted to an
outright sale of the component or spare part that was previously delivered, at
a sales price agreed upon at the time the exchange transaction was negotiated.

AAS has from time to time since its inception also generated revenues from
leasing engines and select airframe components and spare parts to aircraft
operators. Both large and small aircraft operators seeking to lower working
capital requirements, capital expenditures and overhead expenses are
increasingly leasing complete engines rather than maintain spare engine pools.
Under an operating lease, the lessor retains title to the property.
Accordingly, AAS has the ability to re-lease, sell or disassemble the aircraft
or engines for components and spare parts at the expiration of the lease term.

Management believes that there is an increasing demand by customers for not
only engine operating leases, but for rotable inventory aircraft operating
leases. Management also believes that product sales will be enhanced by
expanding leasing services, because AAS will have the opportunity to sell
components and spare parts both for the leased aircraft or engines as well as
other aircraft or engines in the lessee's fleet when needed. Accordingly, AAS
intends to expand the leasing business.

AAS has been rapidly expanding its core business by broadening and increasing
its inventory by acquiring engines, components and spare parts for a variety of
wide-body aircraft. The results of operations to date have depended
substantially upon engine sales and sales of airframe components and spare
parts in the redistribution market for Boeing 737 aircraft and engine
components and spare parts for the Pratt & Whitney JT8 engine series. AAS
intends to expand its CFM56 complete engine and engine components and spare
parts inventory, offer an expanded range of avionics and instrumentation
products, and expand its product lines by adding engines such as the JT9D, CF6
and PW4000 engines used in Boeing 747 and 767 aircraft, the McDonnell-Douglas
DC-10 and the Airbus A300, and the engine components and spare parts and
airframe components and spare parts for those same wide-body aircraft.

Management of AAS also determined that another means to increase revenues and
operating income was to integrate new services and products with its
redistribution capabilities and to become a full service aviation supplier.
Accordingly, in the last quarter of 1998, AAS began the integration by adding
the acquired companies to its operations. AAS now offers engine and landing
gear maintenance, overhaul and repair and engine management services.

PRODUCTS

COMPLETE ENGINES, ENGINE COMPONENTS AND SPARE PARTS. AAS has concentrated on
the Pratt & Whitney JT8 series engines and, to a lesser extent, General
Electric CFM56 engines and their related components and spare parts.. Industry
sources estimate that the JT8D engine powers approximately 40% of commercial
aircraft worldwide, including Boeing 737-100 and -200 aircraft, 727 aircraft
and McDonnell-Douglas DC-9 aircraft. The CFM56 is used to power aircraft
including Boeing 737-300, -400 and -500 aircraft, McDonnell-Douglas DC-8 and a
variety of Airbus aircraft. It is the second most popular engine worldwide
based on the number of aircraft powered by this engine type. Production of the
JT8D ceased in 1987, but operators of existing narrow-body aircraft continue to
maintain their JT8D engines because there is no cost-effective replacement for
those engines.

AAS generally purchases most of its engines in non-serviceable condition,
commissions necessary repairs to a third party licensed repair facility (or to
AAS-Amjet, its own newly acquired FAA licensed repair facility), and then
resells or leases the completely overhauled engines. Where possible, AAS uses
engine components and spare parts from its own inventory in order to minimize
out-of-pocket repair cost and maximize inventory turnover.

AIRFRAME COMPONENTS AND SPARE PARTS. Inventory of airframe components and spare
parts including avionics, hydraulics, landing gear and flight surfaces consists
primarily of rotables for Boeing, McDonnell-Douglas and Airbus aircraft. A
rotable is a part which is removed either periodically as dictated by the FAA,
an original equipment manufacturer or an operator's maintenance procedures, or,
on an as-needed basis. After removal a rotable is typically repaired or
overhauled and either re-used an indefinite number of times or used for a
designated number of allowable flight hours and/or cycles. Airframe components
and spare parts are generally obtained from disassembly of aircraft and
purchase of bulk inventory. After purchase, and disassembly if required, the
components and spare parts are sent to AAS where evaluations are undertaken and
repairs are commissioned as required.

SERVICES

Each of the acquisition transactions in the last quarter of 1998 enabled AAS to
expand the products and services which it offered to its customers. The
services now offered include engine maintenance, overhaul and repair, landing
gear maintenance, overhaul and repair, and engine management services.

ENGINE MAINTENANCE, OVERHAUL AND REPAIR. AAS-Amjet is a FAA licensed 145 repair
facility which specializes in the maintenance, overhaul and repair of JT8D
engines. AAS-Amjet overhauls engines for airlines and other end user customers
as well as on behalf of the Company as a whole. 


                                      -4-


<PAGE>   5




LANDING GEAR MAINTENANCE, OVERHAUL AND REPAIR. Prior to the acquisition of its
assets by AAS, Condor was a redistributor of complete landing gear, as well as
landing gear components and spare parts. Subsequent to the acquisition, it
obtained FAA certification to repair and maintain landing gear. The FAA
certification allows AAS Landing Gear it to overhaul wide-body and narrow body
landing gear, making it one of only a very few non-airline overhaul facilities
in the United States. AAS is currently utilizing the services of AAS Landing
Gear for all maintenance, overhaul and repair work on its owned landing gear.
Like AAS-Amjet, AAS Landing Gear performs maintenance, overhaul and repair
services for entities other than AAS.

ENGINE MANAGEMENT SERVICES. AAS Engine Services provides total engine
management services, including borescoping, trend monitoring, engine condition
analysis and valuation, overhaul management and troubleshooting. Engine
borescoping is a diagnostic procedure in which a video camera is inserted into
engine sections to analyze the condition of an engine without disassembly.
These services are provided to AAS when it has the opportunity to obtain an
engine and to owners of engines who want someone to analyze and evaluate their
engines, arrange for required overhaul or maintenance services and monitor the
provision of those services.

INVENTORY ACQUISITION

AAS obtains most of its component and spare part inventory by purchasing
individual components and spare parts from airlines, manufacturers, repair
facilities or other redistributors; excess inventory from aircraft operators
("bulk inventory purchases"); or aircraft and engines for disassembly.

BULK INVENTORY PURCHASES. AAS makes bulk inventory purchases by bidding on the
inventory of companies that are eliminating certain portions of their component
and spare part inventory. Generally those companies are selling their inventory
because they retired an aircraft type from their fleet, or they instituted an
inventory reduction program to reduce costs, or they are downsizing operations
or they are dissolving their businesses. Bulk inventory purchases generally
allow AAS to obtain large inventories of aircraft components and spare parts at
a lower cost than can ordinarily be obtained by purchasing aircraft components
and spare parts on an individual basis. When AAS acquired substantially all of
the assets of the acquired companies, the purchases included approximately $5.5
million of engines, engine components and spare parts, airframe components and
spare parts and landing gear components and spare parts. These purchases could
also be deemed bulk inventory purchases.

DISASSEMBLY PURCHASES. The availability of aircraft for disassembly varies
based on a number of factors, including demand for older aircraft, the rate at
which aircraft operators retire older aircraft from their fleet, availability
of new aircraft and decisions by cargo carriers to standardize fleets of cargo
aircraft that may formerly have served as passenger aircraft. Sellers are
usually motivated to dispose of their aircraft at prices that justify
disassembly for a variety of reasons, including the seller's need for immediate
liquidity or inability to economically operate the aircraft or to lease the
aircraft to a third party. Additionally, such aircraft may require extensive
maintenance or overhaul or may require government-mandated improvements which
are uneconomical for the seller to perform.

AAS acquires aircraft for disassembly if management believes that it can
recover the total purchase price within three to twenty-four months through the
sale of a portion of the components and spare parts and can sell the remaining
components and spare parts over the subsequent five years. AAS catalogues all
of the hundreds of components and spare parts on an aircraft which is to be
disassembled by using either its own computerized data base information or by
information provided by the seller or, if none is available, by creating its
own data base. AAS enters the list of components and spare parts and all the
relevant information regarding the components and spare parts, including each
part's repair history, into its computer data base. Entry of this data into the
computer data base as soon as the aircraft is purchased enables sales personnel
to begin marketing efforts as soon as the purchase is completed. 

In 1998, AAS acquired and disassembled an Airbus A310 airframe and two Boeing
737-200 aircraft. The aggregate acquisition costs of these three was
approximately $3.2 million, which was funded from a draw under

                                      -5-


<PAGE>   6


a credit facility with NationsBank, N.A. (the "Credit Facility"). AAS retained
a third party contractor to disassemble these aircraft where they were
purchased. During the third quarter of 1998, the third party contractor began
to ship the hundreds of components and spare parts derived by the disassembly
to AAS for cleaning, inspection and evaluation. At the end of the third
quarter, all of the four engines and a significant number of components and
spare parts from the two Boeing 737-200 aircraft had been sold and AAS had
recovered approximately 78% of the purchase price. At December 31, 1998, AAS
had not completed the Airbus A310 disassembly project.

SALES AND MARKETING

AAS has developed a sales and marketing program for its redistribution
activities which includes well-trained and knowledgeable in-house sales
personnel and commissioned independent sales agents, customer service
specialists, computerized inventory management, listing of aircraft components
and spare parts in two electronic industry data base catalogues and a home page
on the Internet.

In addition to directly marketing its inventory, AAS utilizes the services of
independent sales agents who primarily specialize in international sales. Each
sales agent has extensive experience with the requirements of aircraft
operators and other customers. Sales agents are paid on a commission basis and
are retained under agency agreements terminable at will by either party. In
addition to performing sales activities, these sales agents assist in
identifying opportunities to purchase aircraft, engines and bulk components and
spare parts inventories. AAS is focusing on increasing the number of sales
agents in the international market, not only to increase sales, but to help
identify opportunities to purchase aircraft and spare parts on a worldwide
basis.

As a means of generating exposure to existing and potential customers, AAS
lists its inventory in the Inventory Locator Service ("ILS") and the Air
Transport Association's Airline Inventory Redistribution System ("AIRS")
computerized data bases. Buyers of aircraft components and spare parts can
access the ILS or AIRS, as well as other spare parts data bases, to determine
the companies which have the desired inventory available. Neither the ILS nor
AIRS lists price information relating to a particular component or spare part.
AAS also advertises in select industry catalogues and management attends a
number of industry conferences and trade shows in order to acquaint potential
customers with the redistribution capabilities of AAS.

Both manufacturers' prices for new parts and market forces establish the price
for aircraft components and spare parts in the redistribution market. No
pricing service or price catalogue exists for those components and spare parts.
Rather, prices are determined by referencing new parts catalogues with
consideration given to existing supply and demand conditions. Often, aircraft
operators will opt for quality components and spare parts from redistributors
even when new components and spare parts are still in production. Aircraft
components and spare parts sold in the redistribution market must meet the same
FAA quality standards as new components and parts, but they cost less, and are
often more readily available, than new components and parts. Prices for engines
generally depend on the level of thrust, the availability of the engine type at
the time of repair, the availability of alternative engine types that can be
used in a customer's application and whether an aircraft is "on the ground"
awaiting installation of an engine or a spare part.

AAS also markets its engine and landing gear maintenance, overhaul and repair
services and its engine management services to customers purchasing aircraft
components and spare parts, and markets its aircraft components and spare parts
to customers of the engine and landing gear maintenance, overhaul and repair
services and engine management services.

AAS also maintains a website on the Internet which can be located at
HTTP://WWW.A-A-S.COM. The website is designed to create a new channel of sales
and marketing. The web site contains information concerning products
and services available through AAS and the acquired companies. It will
eventually accommodate e-commerce sales transactions and allow customers to
submit orders directly to AAS entirely over the Internet.

                                      -6-

CUSTOMERS

Domestic sales accounted for approximately 77% of total revenues of AAS in 1998
and foreign sales accounted for the remaining approximately 23% of such
revenues. Customers of AAS include over 500 domestic and international
commercial passenger and cargo airlines, maintenance and repair facilities and
other redistributors. In 1998, no customer accounted for in excess of 10% of
net sales, although one customer accounted for 5% of net sales. In a given
period, a substantial portion of the net sales of AAS may be attributable to a
small number of customers due to the substantial cost of engines. However, in
1998, the customer who accounted for 5% of net sales did not purchase an
engine.

QUALITY ASSURANCE

Aircraft operators require a readily available and identifiable source of
components and spare parts meeting regulatory and manufacturing requirements.
Accordingly, AAS maintains stringent quality control standards and procedures
and has implemented a total quality assurance program. In September 1996, the
FAA issued an advisory circular (FAA Advisory Circular 00-56) to support the
implementation of a voluntary accreditation program for civil aircraft parts
suppliers. This accreditation program established quality standards applicable
to suppliers such as AAS, and designated FAA recognized quality assurance
organizations to perform quality assurance audits for accreditation of these
suppliers. AAS is a member of Airline Suppliers Association ("ASA") and that
organization was the FAA recognized quality assurance organization which
performed the initial quality assurance audit for accreditation of AAS. In
October 1998, ASA found that AAS meets requirements of ASA's Quality System
Standard "ASA-100" and the FAA Advisory Circular 00-56 and was accredited. AAS
will be subject to quality assurance audits on an on-going basis in order to
maintain its accreditation. Although accreditation is voluntary and not
required in order to conduct operations, management believes that accreditation
is invaluable as a sales tool. Components and spare parts procured from an
accredited supplier convey assurance to the purchaser that the quality is as
stated and the appropriate documentation is on file at the supplier's place of
business. Accreditation also provides assurance that the supplier has
implemented an appropriate quality assurance system and has demonstrated the
ability to maintain such system.

An important factor in the aircraft components and spare parts redistribution
market relates to the documentation and traceability of aircraft components and
spare parts. AAS requires all of its suppliers to provide adequate
documentation as dictated by customers.

WARRANTIES

AAS provides no warranties with the aircraft components and spare parts it
sells unless the part was repaired by AAS-Amjet or AAS Landing Gear. It
provides a pass-through to its customers of any warranty rights it receives
from third party maintenance and repair facilities. Engine repairs are
customarily warranted by maintenance and repair facilities, including
AAS-Amjet, for a period of six months or 1,000 flying hours. Landing gear
repairs are generally warranted for THE EARLIER OF TEN YEARS OR THE NEXT
OVERHAUL. Only labor and workmanship are warranted on repairs; parts are
warrantied by the manufacturer. AAS generally accepts returns of aircraft
components and spare parts by its customers within a period of 45 days from the
date of sale.

REGULATION

The aviation industry is highly regulated in the United States by the FAA and
in other countries by similar regulatory agencies. These regulations are
designed to ensure that all aircraft and aircraft equipment are continuously
maintained in proper condition to ensure safe operation of aircraft. The
regulations dictate the monitoring, inspection, maintenance and repair
procedures and schedules for the various types of aircraft, engines and
aircraft components and spare parts and require such procedures be performed
only by licensed repair facilities utilizing licensed technicians.
Demonstration of compliance with applicable FAA and manufacturing standards is
required prior to installation of a component or spare part on an aircraft.
Accordingly, AAS only utilizes 

                                      -7-


<PAGE>   8


licensed repair facilities (including AAS Landing Gear and AAS-Amjet) to repair
and certify the products it sells and maintains the quality assurance program
described above to provide customers with required compliance documentation.

Regulations promulgated by the FAA governing noise emission standards for older
aircraft and the FAA's Aging Aircraft Program Plan (the "Aging Aircraft
Program") have a material impact on the market for products of AAS. All stage 2
aircraft must install hush-kits to meet the FAA noise emission standards or be
phased out of operation in the United States by December 31, 1999 and in the
European Union by April 1, 2002. The Aging Aircraft Program requires aircraft
operators to perform structural modifications and inspections to address
airframe fatigue and to implement corrosion prevention and control programs,
which increase the operating and maintenance costs of older aircraft.
Furthermore, the Environmental Protection Agency and the various agencies of
the European Union have sought the adoption of stricter standards limiting the
emission of nitrous oxide from aircraft engines. Management of AAS believes
that certain aircraft operators will continue to utilize older aircraft because
the cost of acquiring new replacement aircraft is substantially greater than
the cost to update an older aircraft to comply with noise emission standards
and the Aging Aircraft Program.

While the redistribution business is not regulated by the FAA, the products AAS
sells to its customers must be accompanied by documentation which enables the
customers to comply with the regulatory requirements applicable to those
customers. AAS-Amjet and AAS Landing Gear, the newly acquired repair
operations, must be certified by the FAA and, in some cases, by original
equipment manufacturers, in order to perform maintenance, overhaul and repair
services. Management believes that these operations are in material compliance
with applicable regulations. Certified repair operations are periodically
inspected and must comply with all regulations to maintain certification.
Personnel at repair facilities must also be certified to perform the services
they provide.

PRODUCT LIABILITY

A catastrophic accident or incident occurs periodically in the commercial
aviation industry. If the incident occurs due to failure of any part of the
aircraft, product liability claims could be asserted against the seller,
manufacturer, repairer or lessor of the part. No lawsuit has ever been filed
against AAS based upon a product liability theory and AAS maintains product
liability insurance in the amount of $100 million. Management believes this
amount is adequate, however, claims could arise in excess of that amount.
Moreover, AAS may be unable to obtain product liability insurance coverage in
the future or it may be only available at an unacceptable cost. The financial
condition of AAS could be adversely affected if it had to pay, or even defend,
a catastrophic product liability claim not fully covered by insurance.

COMPETITION

The aircraft components and spare parts redistribution market is highly
competitive and fragmented. AAS competes against a limited number of
well-capitalized companies offering a broad range of products and services and
numerous small competitors serving distinct market niches. The principal
companies with which AAS currently competes are AAR Corp., The AGES Group,
Aviation Sales Company, AVTEAM, Inc., Banner Aerospace, Kellstrom Industries
and The Memphis Group, all of which are significantly larger and have greater
market share and financial resources than AAS. Customers in need of aircraft
parts also have access, through computer-generated inventory catalogues, to a
broad array of suppliers, including aircraft manufacturers, OEMs of components
and spare parts, airlines and aircraft services companies, which may have the
effect of increasing competition for, and lowering prices on, parts sales.
Management believes that depth of inventories, the ability to provide a broad
array of both products and required services, timeliness, quality and
traceability of products, service and price are the key competitive factors in
the industry. If AAS is unsuccessful in maintaining its competitive position,
it may lose market share and its financial results may be materially adversely
affected.

ITEM 5.   MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

The common stock of AAS is quoted on The Nasdaq Stock Market(R) under the
trading symbol AIRS. The following table sets forth the range of high and low
closing sale prices, as reported by The Nasdaq Stock Market, from May 28, 1998
(the date on which the common stock commenced trading) through December 31,
1998. The prices set forth below reflect interdealer quotations, without retail
markups, markdowns or commissions, and may not represent actual transactions.

    FISCAL YEAR 1998                       HIGH                        LOW   
    ----------------                    ---------                   ---------
    May 28, 1998 through end of 
      Second Quarter                    $  6.25                     $ 6.00
    Third Quarter                          6.25                       4.25
    Fourth Quarter                         9.75                       4.50

On March 10, 1999, the closing sale price of the common stock was $9.625. As
of March 10, 1999, the number of record shareholders of the common stock was
approximately 35. The number of sets of proxy material for the upcoming Annual
Meeting of Shareholders requested by brokers for their beneficial owners
indicates that there are approximately 975 beneficial shareholders.

Holders of common stock are entitled to receive such dividends as may be
declared by the Board of Directors. In connection with the termination of its S
Corporation status, AAS distributed to its shareholders a total of $2.4
million. This amount represented approximately 50% of the accumulated taxable
income not previously distributed plus an amount equal to the estimated 1998
tax liability of its stockholders through the date of termination of the S
Corporation election. Other than that distribution, the Board of Directors has
never declared or paid any cash dividends and it does not anticipate paying any
cash dividends on its common stock in the foreseeable future.

UNREGISTERED SECURITIES. AAS issued unregistered shares of its common stock as
part of the purchase price in each of the transactions with the acquired
companies. It issued 625,000 shares of common stock valued at $3,750,000 to
Amjet, 90,104 shares of common stock valued at $518,100 to GTI and TII, and
125,000 shares of common stock valued at $750,000 to Condor. All of these
issuances were made to acquired companies whose principals had access to
information enabling them to evaluate the merits and risks of the investment by
virtue of their relationship to AAS, the business of their respective acquired
companies and their economic bargaining power. AAS relied on Section 4(2) of
the Securities Act of 1933, as amended (the "Act") for the exemption from the
registration requirements with respect to such issuances.

For a period of one year, the acquired companies may "piggy-back" the shares
acquired pursuant to their respective agreements onto certain types of
registration statements which AAS files to register its securities under the
Act for a public offering. Each of the acquired companies also was granted the
right to a "demand" that AAS file a registration statement under the Act
covering their respective shares. The "demand" registration right commences
after July 1, 1999 with respect to Amjet and GTI and September 1, 1999 with
respect to Condor. The respective demand rights may only be exercised on one
occasion. All expenses incurred in connection with the registration of these
shares, excluding underwriting discounts or fees, are payable by AAS.

USE OF PROCEEDS OF THE INITIAL PUBLIC OFFERING. AAS registered 2,300,000 shares
of common stock for sale to the public on a Form SB-2 Registration Statement
(Reg. No. 333-48497) (the "Registration Statement") declared effective on May
28, 1998. AAS also registered 200,000 warrants to purchase shares of common
stock and 200,000 shares of common stock underlying such warrants issued to
Cruttenden Roth Incorporated, the underwriter of the public offering.

                                      -12-


<PAGE>   13


A closing on the initial public offering of 2,000,000 shares of common stock
was held June 2, 1998 and a closing on an additional 250,000 over-allotment
shares of common stock was held July 14, 1998. AAS received aggregate gross
proceeds of $13.5 million from the sale of these 2,250,000 shares at an
offering price of $6.00 per share. Expenses incurred by AAS in connection with
the issuance and distribution of these shares were $945,000 for underwriting
discounts and commissions, $270,000 for expenses paid to or for underwriters,
and $641,000 for other expenses (consisting of registration fees, filing fees,
legal fees, printing and engraving, consulting fees, accounting fees and
transfer agent fees and costs, appraisal fees, insurance costs, presentation
and travel expense), for total expenses of $1,856,000. Included in other
expenses were legal fees of $182,000 (of which $96,000 was paid to a
co-counsel) paid to a law firm in which a director of AAS is a partner. No
other expenses were direct or indirect payments to directors, officers or their
associates or to persons owning ten percent or more of any class of equity
securities of AAS or to affiliates of AAS. The resulting net offering proceeds
after payment of all expenses was $11,644,000.

The net offering proceeds were used as follows: an aggregate of $3.0 million to
repay advances from two stockholders and to make distributions to those two
stockholders in connection with the termination of the S- Corporation status of
AAS, $3.0 million for repayment of a portion of outstanding indebtedness and
$5.6 million to acquire additional inventory. One of the stockholders receiving
a portion of the $3.0 million amount is an officer, director and principal
shareholder and the other is a principal shareholder. No other expenditures
were direct or indirect payments to directors, officers or their associates or
to persons owning ten percent or more of any class of equity securities of AAS
or to affiliates of AAS. Furthermore, the use of proceeds described above does
not represent a material change in the use of proceeds described in the
prospectus contained in the Registration Statement. Substantially all of the
proceeds have been expended and this is the final required report of the use of
the proceeds.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE FINANCIAL
STATEMENTS (AND NOTES THERETO) APPEARING ELSEWHERE IN THIS REPORT ON FORM
10-KSB.

OVERVIEW

AAS is an international supplier of aviation services, which include sales of
aircraft components and spare parts in the redistribution market, maintenance,
overhaul and repair of those products, and engine management services,
primarily to other maintenance and repair facilities, major commercial
passenger and cargo airlines and other redistributors located throughout the
world. Historically, revenues have principally been derived from the
redistribution of engine components and spare parts for the Pratt & Whitney JT8
series of engines and, to a lesser extent, the General Electric CFM56, as well
as avionics, rotable, repairable and expendable airframe components and spare
parts for Boeing, McDonnell-Douglas and Airbus aircraft. AAS fulfills
customers' requirements for engine and airframe components and spare parts
through purchases of surplus aircraft for disassembly, bulk purchases of
aircraft components and spare parts from aircraft operators, purchases of
individual components and spare parts from other redistributors, consignments
from aircraft operators and others, and exchanges of inventoried aircraft
components and spare parts for components and spare parts that require service
or overhaul.


                                     -13-
<PAGE>   14

In the last quarter of 1998, AAS began to implement an acquisition strategy
aimed primarily at integrating its aviation capabilities with related products,
such as engine management services, maintenance, overhaul and repair services
and manufacturing capabilities, and becoming a full service "one stop" supplier
of both products and services for customers. Between October 1, 1998 and
November 19, 1998, using three newly formed subsidiaries to acquire
substantially all of the assets, including inventory, of the acquired
companies. All of the acquisitions have been accounted for under the purchase
method of accounting. As a result, revenues in the last quarter of 1998 include
revenues from the provision of FAA certified overhaul and maintenance services
through AAS-Amjet and AAS Landing Gear and engine management services through
AAS Engines, services previously provided by certain of the acquired companies.
The material financial terms of each of the asset purchase transactions are set
forth below.

GTI AND TII. AAS acquired substantially all of the assets of GTI and TII for a
purchase price $1.1 million and assumption of certain accounts payable not to
exceed $305,013. The purchase price was comprised of $586,932 cash paid from
working capital and issuance of 90,104 shares of common stock valued at
$518,100.

CONDOR. AAS acquired substantially all of the operating assets of Condor for a
purchase price $1.75 million. The purchase price was comprised of $1.0 million
cash paid from working capital and issuance of 125,000 shares of common stock
valued at $750,000. Condor received one-half of the cash payment on November 9,
1998 and the other one-half of the cash payment and the shares of common stock
on November 30, 1998, the date upon which it received FAA certification to
overhaul and maintain landing gear for commercial aircraft.

AMJET. AAS acquired substantially all of the assets of Amjet for a purchase
price of $12.25 million and assumption of certain accounts and trade payables,
certain warranty claims, employee bonuses, and claims and liability arising
from specified investigations. The purchase price was comprised of
approximately $8.5 million cash paid from the Credit Facility, the issuance of
625,000 shares of common stock valued at $3.75 million. In addition, AAS
acquired the inventories of GASI and AAC for an aggregate purchase price of
$2.55 million cash, also paid from the Credit Facility.

AAS was incorporated in the State of South Carolina under the name Aviation
Alloys, Inc. in June 1985 and commenced active operations under its current
name in 1990. It was recapitalized, reincorporated in the State of Delaware and
converted from a S Corporation to a C Corporation immediately prior to its
initial public offering in May 1998. The statement of operations data includes
a pro forma provision for federal and state income taxes as if AAS were a C
Corporation subject to federal and state income taxes for all years presented.
See Note 3 to Financial Statements for more information. The statement of
operations data also includes pro forma net income, pro forma earnings per
share and pro forma weighted average shares outstanding to take into account
the public offering in May 1998.

RESULTS OF OPERATIONS

The operating results of AAS are affected by many factors, including the volume
and timing of orders from large customers, the timing of expenditures and
method of purchasing inventory in anticipation of future sales, and the mix of
aircraft engines and components and spare parts contained, at any time, in the
Company's inventory or sold during any period. A large portion of the Company's
operating expenses are relatively fixed. Since the Company typically does not
obtain long-term purchase orders or commitments from its customers, it must
anticipate the future volume of orders based upon the historic purchasing
patterns of its customers and upon its discussions with its customers as to
their future requirements. Cancellations, reductions or delays in orders by a
customer or group of customers could have a material adverse effect on the
Company's business, financial condition and results of operations.

The table on the following page sets forth, for the periods indicated, the
percentage of net sales represented by certain items included in the statements
of operations:

COMPARISON OF YEARS ENDED DECEMBER 31, 1998 AND 1997

Net sales (gross sales, net of allowances for returns) for 1998 increased $13.1
million, or 98.3%, to $26.3 million from $13.2 million in 1997. Growth in the
sales of engines, engine components and airframe components and spare parts by
AAS accounted for approximately 72% of the total $13.1 million increase. Sales
associated with the companies acquired during the fourth quarter accounted for
approximately 28%. Sales to international customers of engine and airframe
components and spare parts increased approximately $2.0 million, to
approximately $6.0 million in 1998 as compared to approximately $4.2 million in
1997; however, as a percentage of net sales, international sales of engine and
airframe components and spare parts decreased to 23% of net sales in 1998 from
30% of net sales in 1998.

Cost of sales increased $8.1 million, or 101.3%, to $16.0 million in 1998 as
compared to $7.9 million in 1997. As a percentage of net sales, the increase
was 0.9%. Cost of sales consists primarily of product costs (acquisition costs
and costs associated with repairs, overhaul or certification), freight charges
and certain labor and overhead expenses. Gross profit increased to $10.3
million in 1998 from $5.3 million in 1997. As a percentage of net sales, gross
profit decreased slightly to 39.1% in 1998 from 40.0% in 1997. The increase in
cost of sales as a percentage of revenue and the decrease in gross profit as a
percentage of revenue was due primarily to the increase in the labor intensive
activities associated with repair and overhaul operations, which added
significant direct labor and overhead expenses to the cost of sales.

Selling and marketing expenses increased $968,000, or 137.7%, to $1.7 million
in 1998 from $703,000 in 1997. This increase is primarily due to outside sales
office expense, commissions paid to agents on increased sales volumes in 1998,
compensation expenses related to additional sales personnel, sales related
travel and advertising costs, and increased sales expenses relating to the
acquired companies. As a percentage of net sales, selling and marketing
expenses increased to 6.4% in 1998 from 5.3% in 1997.

General and administrative expenses increased $1.1 million, or 195.5%, to $1.7
million in 1998 from $564,000 in 1997. This increase is primarily due to the
addition of compensation expense associated with the employment of the
principals and employees of the companies acquired during the fourth quarter
and the new occupancy charges, such as rent and depreciation, associated with
the facilities of the acquired companies. Also included in 1998 expenses are
increased occupancy charges associated with the addition of corporate offices
and warehouse space and professional fees and insurance premiums associated
with operating as a public entity. As a percentage of net sales, general and
administrative expenses increased to 6.3% in 1998 from 4.3% in 1997.

Net other expense totaled $185,000 in 1998 as compared to net other income of
$36,000 in 1997. Although interest income and other income increased by
approximately $25,000 in 1998, primarily from investment of the public offering
proceeds, interest expense on higher levels of indebtedness outstanding under
the Credit Facility increased approximately $245,000.

As a result of the above, net income before taxes increased $2.7 million, or
66.1%, to $6.8 million in 1998 from $4.1 million in 1997. AAS was not subject
to federal and state income taxes in 1997 and only became subject to

                                      -15-


<PAGE>   16



such taxes on May 28, 1998 when it terminated its election to be taxed as an S
Corporation in connection with its initial public offering. Actual net income
after income tax expense of $1.8 million was $5.0 in 1998. However, to allow
comparisons with C Corporations, pro forma federal and state income taxes have
been assumed to reflect the reconciliation between the statutory provision for
income taxes and the actual pro forma income tax provision. Based on this
assumption, AAS would have incurred pro forma income taxes of $2.6 million in
1998 and $1.6 million in 1997, resulting in pro forma net income of $4.2
million and $2.4 million in 1998 and 1997, respectively.

COMPARISON OF YEARS ENDED DECEMBER 31, 1997 AND 1996

Net sales increased $4.8 million, or 58.6%, to $13.2 million in 1997 from $8.4
million in 1996. Sales to international customers increased $3.2 million, to
$4.2 million in 1997 from $1.0 million in 1996, as AAS obtained new customers
in Europe and the Far East during 1997.

Cost of sales increased $2.4 million, or 45.0%, to $7.9 million in 1997 from
$5.5 million in 1996. Gross profit increased to $5.3 million in 1997 from $2.9
million in 1996, reflecting an increase in gross profit as a percentage of net
sales to 40.0% from 34.4%. The increase in gross profit was due primarily to
increased engine and engine component and spare part sales in 1997 as compared
to 1996, which generally carry higher margins than airframe components and
spare parts.

Selling and marketing expenses increased $152,000, or 27.6%, to $703,000 in
1997 from $551,000 in 1996. This increase primarily reflects commissions paid
to agents in 1997, higher compensation to sales personnel and travel related
sales costs. As a percentage of net sales, selling and marketing expenses
declined to 5.3% in 1997 from 6.6% in 1996.

General and administrative expenses increased $186,000, or 49.4%, to $564,000
in 1997 from $378,000 in 1996. This increase reflects increased personnel
expense resulting from higher staffing levels, expenses associated with
relocation to a new headquarters facility, increased insurance expense, and an
increase in the discretionary contribution by AAS to the employee profit
sharing plan. As a percentage of net sales, general and administrative expenses
declined to 4.3% in 1997 from 4.5% in 1996.

Net other income totaled $36,000 in 1997 compared to net other expense of
$1,000 in 1996. While interest expense increased to $79,000 in 1997 from
$74,000 in 1996, interest income increased to $81,000 in 1997 from $71,000 in
1996 and other income increased to $35,000 in 1997 from $1,000 in 1996.

As a result of the above, net income increased $2.1 million, or 109.6%, to $4.1
million in 1997 from $1.9 million in 1996. As AAS was not subject to federal
and state income taxes. However, to allow comparisons with C Corporations, pro
forma federal and state income taxes have been assumed at a combined 40% rate.
Based on this assumption, AAS would have incurred pro forma income taxes of
$1.6 million in 1997 and $777,000 in 1996, resulting in pro forma net income of
$2.4 million and $1.2 million in 1997 and 1996, respectively.

LIQUIDITY AND CAPITAL RESOURCES

The primary sources of liquidity for AAS prior to completion of the May 1998
initial public offering were cash flow from operating activities, borrowings
under the Credit Facility and advances from its two founders. AAS requires
capital to purchase inventory, to fund product servicing and overhaul
facilities, for normal operating expenses and for general working capital
purposes.

The Credit Facility was initially established with NationsBank in June 1995. In
July 1998, AAS entered into a new agreement with NationsBank which expanded its
revolving Credit Facility. This new Credit Facility permits borrowings of up to
$30.0 million, $10.0 million of which replaced the working capital line which
was to mature September 30, 1998 and $20.0 million of which was restricted to
funding acquisitions. The new Credit Facility was amended in March 1999 to
permits borrowings of up to $35.0 million, $15.0 million for working capital
and $20.0 million for acquisitions. This is a revolving credit line, with
principal due on maturity and interest payable monthly. The Credit Facility
bears interest at the London Interbank Offered Rate ("LIBOR") plus an amount
between 1.25% and 2.5%, is secured by accounts receivable and inventory, and
matures June 30, 2000. As of 

                                      -16-


<PAGE>   17



December 31, 1998, AAS had $3.2 million outstanding under the working capital
line of the Credit Facility and $13.0 million outstanding under the acquisition
line of the Credit Facility. The financial situation of AAS changed
significantly upon completion of the May 1998 initial public offering and the
receipt of net proceeds of $11.6 million from the offering. It changed
significantly again in the fourth quarter of 1998 as a result of AAS making
significant cash payments and borrowings in its acquisition of the assets of the
acquired companies and incurring significant fees and expenses in connection
with such transactions.

As of December 31, 1998, the principal sources of liquidity included cash and
cash equivalents of $2.2 million, net accounts receivable of $4.0 million, and
$6.8 million and $7.0 million of borrowings still available under the working
capital line and acquisition line, respectively, of the Credit Facility. AAS
had working capital of $19.7 million and $11.3 million of long-term debt as of
December 31, 1998.

For the year ended December 31, 1998, operating activities used cash of $6.9
million, primarily for increases in inventory, partially offset by net income
and increases in accounts payable and accrued expenses. Net cash used in
investing activities during the year ended December 31, 1998 was $13.5 million,
reflecting the purchase of certain fixed assets and investments, while net cash
provided by financing activities during the same period was $21.8 million,
consisting primarily of proceeds from the public offering, net of offering
transaction costs, and borrowings under the Credit Facility, partially offset
by debt repayments and distributions in connection with the termination of the
S-Corporation status of AAS.

Capital expenditures were approximately $2.8 million and $263,000 in 1998 and
1997, respectively. The expenditures in 1998 were primarily for equipment and
leasehold improvements in facilities of the acquired companies and in the new
plating facility currently under construction. Expenditures in 1997 were
primarily for furniture and fixtures installed in the corporate headquarters
facility. At December 31, 1998, the Company had outstanding commitments to
acquire machinery and equipment of approximately $2.0 million.

Existing cash balances, accounts receivable and amounts available under the
Credit Facility should be sufficient to meet capital requirements for at least
the next 12 months. If capital requirements increase thereafter, AAS could be
required to secure additional sources of capital. It may not be capable of
securing additional capital or the terms upon which such capital could be
secured may not be acceptable.

INFLATION

Although management cannot accurately anticipate the effect of inflation on
operations, it does not believe that inflation has had, or is likely in the
foreseeable future to have, a material effect on results of operations or the
financial condition of AAS. Increases in fuel costs due to inflation may
adversely affect demand for used aircraft, thereby decreasing demand for
aircraft components and spare parts.

YEAR 2000 ISSUES

AAS is cognizant of the issues associated with the programming code in existing
computer systems and devices that utilize microchip processors as the year 2000
approaches. The "Year 2000" problem is pervasive and complex, as virtually
every computer operation will be affected in some way by the rollover of the
two-digit year value to "00". Computer systems that do not properly recognize
date-sensitive information when the year changes to 2000 could generate
erroneous data or fail.

In the ordinary course of business, AAS has replaced or is in the process of
replacing non-compliant hardware and software in all of its facilities as well
as those of the acquired companies with systems that are Year 2000 ready. AAS
has confirmed with the licensors of financial information and operational
applications that have been licensed from outside vendors that those products
are Year 2000 ready.

The information system used by AAS in tracking and processing inventory
currently is non-compliant. AAS has contracted for the development of a
proprietary system to replace the existing system. Testing and implementation
of the system is expected to be completed in the third quarter of 1999. Should
management assess that the new system will not be implemented prior to the end
of 1999, AAS can purchase and install upgrades of the existing system that are
or will be Year 2000 ready at a cost approximating $50,000.

Year 2000 issues may also affect the computer systems of the customers, vendors
and financial institutions with which AAS and the acquired companies do
business. AAS has made inquiry of significant customers, vendors and financial
institutions and has been advised that these customers expect to be Year 2000
ready in sufficient time to allow for testing and system implementation before
December 31, 1999.

Management of AAS believes all of its systems and those of the acquired
companies will be fully Year 2000 ready by September 30, 1999 and that amounts
currently budgeted for hardware and software upgrades will be sufficient to
address expenses associated with any Year 2000 issues. Approximately $225,000
was expended during 1998 and approximately $500,000 is budgeted for expenditure
during 1999 for information systems acquisition and development. As many of
these expenditures are for information and operational systems enhancements, a
significant portion of these expenditures will be capitalized and amortized.
Management does not anticipate that any other material expenditures will be
necessary to achieve Year 2000 compliance. Failure to achieve full Year 2000
compliance prior to December 31, 1999 could have a material adverse impact on
results of operations of AAS.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of
American Aircarriers Support, Incorporated and Subsidiaries

We have audited the accompanying consolidated balance sheets of American
Aircarriers Support, Incorporated and Subsidiaries as of December 31, 1998 and
1997 and the related consolidated statements of operations, stockholders'
equity and cash flows for the years then ended. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of American
Aircarriers Support, Incorporated and Subsidiaries as of December 31, 1998 and
1997, and the results of their operations and their cash flows for the years
then ended in conformity with generally accepted accounting principles.

           AMERICAN AIRCARRIERS SUPPORT, INCORPORATED AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of
American Aircarriers Support, Incorporated, a Delaware corporation and its
wholly-owned subsidiaries AAS Engine Services, Inc., AAS Landing Gear Services,
Inc., and AAS Amjet, Inc. (collectively "AAS" or the "Company"). All
significant intercompany accounts and transactions have been eliminated in
consolidation. Certain pro forma information has been provided in connection
with the initial public offering of securities (Note 3).

DESCRIPTION OF BUSINESS

AAS is an international supplier of aviation services including the sale,
maintenance, repair and overhaul of spare parts and engines to major commercial
and cargo airlines, maintenance and repair facilities and other parts
distributors. The company specializes in both engines and airframe parts,
primarily for Boeing, Douglas and Airbus aircraft. AAS also offers engine
management services, and maintenance, repair and overhaul ("MRO") services for
engines and landing gear at its FAA licensed facilities. The Company's
headquarters and distribution facility is located in Fort Mill, South Carolina.
The Company's FAA licensed facilities are located in Miami, Florida.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH AND CASH EQUIVALENTS

The Company considers all liquid investments purchased with a maturity of 90
days or less to be cash equivalents. Included in cash equivalents are
investments in overnight repurchase agreements and a tax-exempt money market
mutual fund. These investments are recorded at cost, which approximates market.

TRADE RECEIVABLES

The Company's allowance for doubtful accounts is based on management's
estimates of the creditworthiness of its customers, and, in the opinion of
management is believed to be set in an amount sufficient to respond to normal
business conditions.

INVENTORIES

Inventories are valued at lower of cost or market. The cost of aircraft parts
purchased individually is determined on a specific identification basis, which
includes the cost associated with the overhaul and repair necessary for resale.
For parts acquired through bulk purchases or through whole aircraft purchases,
the costs are assigned to pools, which are amortized as part sales are
recognized. The amount of cost amortized is based upon the gross profit
percentage as determined from the estimated sales value of the parts. The sales
value estimates and gross profit percentages are based on historical
experience, are monitored by management, and are adjusted periodically as
necessary.

As a result of the acquisitions of FFA licensed MRO facilities, the Company
maintains raw materials and work in process inventories in support of those
overhaul facilities. The cost of the work in process inventory is the direct
labor and overhead costs determined by the labor hours attributed to it.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ASSETS HELD FOR LEASE

The Company leases engines to the airline industry on a worldwide basis through
operating leases. Operating income is recognized on a straight-line basis over
the term of the underlying leases. The cost of the asset held for lease is
amortized, principally on a straight-line basis, to the estimated remaining net
realizable value over the lease term or the economic life of the asset.
Accumulated amortization at December 31, 1998 was $31,000.

PROPERTY AND EQUIPMENT

Property and equipment is recorded at cost. Depreciation of furniture, fixtures
and equipment is provided under the straight-line method over the estimated
useful lives, generally five and seven years. Amortization of leasehold
improvements is provided on the straight-line method over the estimated useful
lives of leased assets or the term of the lease, whichever is shorter. Repair
and maintenance costs are charged to operations as incurred while major
improvements are capitalized. When assets are retired or disposed of, the cost
and accumulated depreciation thereon are removed from the accounts and any
gains or losses are included in operations.

INTANGIBLE ASSETS

Goodwill represents the excess of cost over the fair value of the net assets of
businesses acquired and is amortized using the straight-line method over 30
years. The Company assesses the recoverability of goodwill whenever adverse
events or changes in circumstances or business climate indicate that expected
future undiscounted cash flows may not be sufficient to support the recorded
asset. Based upon its most recent analysis, management of the Company believes
that no material impairment of goodwill exists. Accumulated amortization at
December 31, 1998 was $87,495.

REVENUE RECOGNITION

Revenue from the sales of parts and related costs is recognized when products
are shipped to the customer. Revenue from engine sales is recognized when the
title and risk of ownership are transferred to the customer, which is generally
upon delivery of the engine. The Company provides its customers the right to
return products within 45 days of shipment. The effect of this program is
estimated and a provision for sales returns and allowances is established. The
Company also warehouses and sells inventories on behalf of others under
consignment agreements. The Company records revenues on the sale of consigned
inventories upon shipment of the part. The Company exchanges rotable parts in
need of service or overhaul for new, overhauled or serviceable parts in its
inventory for a fee. Fees on exchanges are recorded when the products are
shipped.

Revenues from fixed-fee contracts for MRO sales are recognized on the
percentage-of-completion method, measured by the cost-to-cost method,
commencing when progress reaches a point where experience is sufficient to
estimate final results with reasonable accuracy.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

REVENUE RECOGNITION (continued)

Provisions for estimated losses on uncompleted contracts, if any, are made in
the period in which such losses are determined. Changes in job performance, job
conditions and estimated profitability, including final contract settlements,
may result in revisions to costs and income and are recognized in the period in
which the revisions are determined.

Warranties on MRO workmanship varies from six months to 10 years dependent upon
a number of factors including the type of part repaired, flight hours, and the
expected life of a part. Manufacturers' warranties for any new or replacement
parts are passed through to the customer.

The asset, "Costs and estimated earnings in excess of billings on uncompleted
contracts" represents revenues recognized in excess of amounts billed. The
liability "Billings in excess of costs and estimated earnings on uncompleted
contracts" represents billings in excess of revenues recognized.

PRO FORMA EARNINGS PER SHARE (UNAUDITED)

In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share," which is required to be adopted for the fiscal years ending after
December 15, 1997. SFAS No. 128 supercedes APB Opinion No. 15, "Earnings Per
Share" and specifies the computation, presentation and disclosure requirements
for earnings per share ("EPS") for entities with publicly held common stock or
potential common stock. Essentially, this Statement replaces the primary EPS
and fully diluted EPS presentations under APB Opinion No. 15 with a basic EPS
and a diluted EPS. Pro forma earnings per share for all periods presented have
been determined under the provisions of SFAS No. 128, and include certain pro
forma adjustments to income and shares as discussed in Note 3.

INCOME TAXES

Prior to the reincorporation and initial public offering discussed in Note 3,
the Company, with the consent of its stockholders, elected to be taxed as an S
Corporation for federal and state income tax purposes as defined in Section
1361 of the Internal Revenue Code of 1986. Therefore, the Company was generally
exempt from all federal and state income taxes as stockholders of the Company
were taxed on corporate income. In connection with the reincorporation, on May
28, 1998, the Company terminated its S-corporation income tax election.

Following the termination of the S-corporation election, the Company became
subject to federal and state income taxes. At that time, the Company adopted
the provisions of SFAS No. 109, ACCOUNTING FOR INCOME TAXES. Under SFAS No.
109, deferred tax assets or liabilities are computed based upon the difference
between the financial reporting and income tax basis of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to be realized or settled. Deferred income
taxes reflect the net tax effect of temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes. Pro forma income and earnings per share
have been determined using estimated effective federal and state income tax
rates as discussed in Note 3.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair value approximates book value for the following financial instruments due
to their short-term nature: cash and cash equivalents, accounts receivable, and
accounts payable. Fair values of notes payable and long-term debt are based on
estimates using present value techniques. Fair values of investments accounted
for at cost were based on prices of recently-made investments in the companies,
and at December 31, 1998 and 1997 approximated carrying values.

At December 31, 1998 and 1997, the carrying values of the Company's notes
payable and long-term debt approximated their fair values as the interest rates
on such financial instruments are comparable to market rates and/or remaining
principal is due in a relatively short period of time. Fair value of unused
line of credit arrangements approximate carrying value as the terms are at
current market for similar agreements.

CONCENTRATIONS OF CREDIT RISK

Financial instruments which potentially subject the Company to concentrations
of credit risk consist of cash and cash equivalents, accounts receivable and
investments.

Cash balances in financial institutions periodically exceed amounts insured by
the FDIC. These balances and investments in overnight repurchase agreements are
held by a national financial institution and management believes risk of loss
related to these amounts is remote.

Accounts receivable subject the Company to a potential concentration of credit
risk. Receivables are usually due within 30 days and the Company performs
periodic credit evaluations of its customer's financial condition.
Substantially all of the Company's customers are in the aviation industry and
sales are usually affected by the current economic condition of the industry.
Sales to international customers have accounted for an increasing amount of net
sales in recent years. The Company anticipates that international sales will
continue to represent a material portion of the Company's net sales in future
periods. Sales to international customers may be subject to greater risks,
including variations in local economies, fluctuating exchange rates and greater
difficulty in accounts receivable collection.

In a given period, a substantial portion of the Company's net sales may be
attributable to the sale of one or more engines. Sales of engines, the timing
of aircraft spare parts sales or a lease transaction during a given period may
result in a customer being considered a major customer of the Company for that
period. In 1998 and 1997, none of the Company's customers accounted for in
excess of 10% of net sales. Currently, the Company believes that it has no
customer, the loss of which would have a material adverse effect on the
Company's results of operations.

USE OF ESTIMATES

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

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ADVERTISING COSTS

The Company expenses advertising costs as they are incurred. Advertising costs
were $74,136 in 1998, and $17,437 in 1997, respectively.

SEGMENT INFORMATION

The Company is in one business segment, as a supplier of aviation services
including the sale, maintenance, repair and overhaul of spare parts and
engines, and follows the requirement of SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information."

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" (SFAS No. 133). This statement addresses the accounting
for derivative instruments, including certain derivative instruments imbedded
in other contracts, and hedging activities. The Statement is effective for all
fiscal quarters of all fiscal years beginning after June 15, 1999. Management
does not anticipate the adoption of the provisions of SFAS No. 133 will
significantly impact the Company's financial reporting.

NOTE 3.  REINCORPORATION AND INITIAL PUBLIC OFFERING

Through an initial public offering (the "Offering") which commenced on May 28,
1998, the Company sold 2,250,000 shares of common stock (including the purchase
of 250,000 shares on July 10, 1998 by the lead underwriter through the exercise
of the over-allotment option). Immediately prior to the effective date of the
registration statement, the then existing stockholders of the South Carolina
corporation (American Aircarriers Support, Inc. or "AASINC") exchanged all
outstanding shares of AASINC for 4.1 million shares of common stock of AAS, and
AASINC merged with and into AAS (together, the "Reincorporation"). AAS was
formed for the purpose of reincorporating in Delaware and otherwise had no
operations. The authorized capital stock of AAS consists of 20,000,000 shares
of common stock and 2,000,000 shares of preferred stock. The authorized capital
stock of AASINC consisted of 100,000 shares of common stock, $1 par value. At
December 31, 1997, 100 shares were outstanding. The balance sheets, statements
of stockholders' equity, and pro forma earnings per share calculations give
effect to the stock issued in connection with the Reincorporation.

Gross proceeds of the Offering totaled $13,500,000 with expenses related to the
Offering totaling $1,856,000. As part of the Offering, the Company granted
warrants to purchase 200,000 shares of common stock at a price of $7.98 per
share to the underwriters. The warrants expire on June 2, 2003.

The proceeds of the Offering were used to repay shareholder advances, repay a
portion of the Company's line of credit, pay distributions to shareholders and
to purchase additional inventory.

NOTE 3.  REINCORPORATION AND INITIAL PUBLIC OFFERING (CONTINUED)

In connection with the reincorporation, on May 28, 1998, the Company terminated
its S Corporation income tax election. The pro forma data on the statement of
operations provides information as if the Company had been treated as a C
Corporation for income tax purposes for all periods presented. Pro forma net
income includes a provision for income taxes as if the Company were subject to
federal and state income taxes as described above at a combined effective tax
rate of approximately 38 percent in 1998 and 40 percent in 1997. The following
unaudited pro forma information reflects the reconciliation between the
statutory provision for income taxes and the actual pro forma income tax
provision.

consisting of $1.0 million in cash and 125,000 shares of the Company's Common
Stock. Stock issued in the acquisition was valued at $6.00 per share based on
the market price of the stock near the date on which the parties agreed to the
terms of the acquisition. Condor received FAA certification to overhaul and
maintain landing gear for commercial aircraft on November 30, 1998.

The acquisitions were accounted for under the purchase method of accounting.
Accordingly, the results of operations are included in the accompanying
consolidated financial statements from the dates of acquisition. The purchase
prices, including $470,000 of acquisition costs, have been allocated to assets
acquired and liabilities assumed based on their fair values at the dates of
acquisition. The excess of the purchase price over the fair value of net assets
acquired in the AMJET acquisition of approximately $10 million has been
recorded as goodwill and is being amortized on a straight-line basis over 30
years.

NOTE 8.  INVESTMENTS

During 1998 and 1997, the company made investments totaling $410,000 in two
joint venture arrangements with Global. In October 1998, the Company acquired
the remaining interest in the joint ventures in connection with the acquisition
of the assets of Global. (See note 4). Prior to October 1998, the investment
was accounted for on the equity method. Income recognized from the joint
venture through September 30, 1998 totaled $48,000.

The Company made investments of $50,000 in 1997 and $50,000 in 1996 in
nonpublic companies, which were accounted for at cost. The investment made in
1997 was in a company in which a director is a principal. In conjunction with
the initial public offering, these two investments were included as part of the
distributions, in connection with the termination of the Company's
S-Corporation status, to the then existing common stockholders. The investments
were distributed at estimated fair value, which was equivalent to carrying
value, in lieu of an equal portion of cash.

NOTE 9.  LINE OF CREDIT

The Company's credit facility was initially established with a bank in June
1995. On July 13, 1998, the Company entered into an agreement with the bank for
an expanded $30 million credit facility. Under the terms of the agreement, $10
million replaced the Company's existing revolving credit line which was due to
mature September 30, 1998. The line of credit bears an annual interest rate
equal to the three-month London Interbank Offered Rate ("LIBOR") plus an amount
between 1.25% and 2.50% based upon the Company's financial performance. On
December 31, 1998, there was $3,250,000 outstanding under the revolving line of
credit bearing a LIBOR-based interest rate of 6.3%.

The remaining $20 million of the credit facility was established as the
Company's acquisition line of credit, at the same annual interest rate, plus an
unused commitment fee of between 10 and 20 basis points. The acquisition
portion of the Company's credit facility requires any used portion to be
converted to a term loan which amortizes in equal monthly installments over a
five year period. On December 31, 1998, $13 million of the acquisition portion
of the credit facility had been converted to term loans.

NOTE 9.  LINE OF CREDIT (CONTINUED)

The credit facility matures June 30, 2000 and is collateralized by the
Company's accounts receivable and inventory. The credit facility requires the
Company to meet certain financial covenants. On December 31, 1998, the Company
was in compliance with all covenants of the credit facility. At December 31,
1998, approximately $1,900,000 of retained earnings were free of restrictions
under the most restrictive of these covenants.

In March 1999, the facility was modified to increase the revolving working
capital portion borrowing limit to $35 million, and to change the criteria of
certain debt ratios imposed under the borrowing base and principal repayment
structure.

NOTE 12.  INCOME TAXES

Prior to the Reincorporation on May 28, 1998 (see Note 3), the Company had
elected to be taxed as an S Corporation for federal and state income tax
purposes as defined in Section 1361 of the Internal Revenue Code of 1986.
Therefore, prior to May 28, 1998, the Company was generally exempt from all
federal and state income taxes as stockholders of the Company were taxed on
corporate income. As a result of the Reincorporation, the Company terminated
its S Corporation election and became subject to federal and state income taxes
at the corporate level. Net deferred tax assets of approximately $40,000 were
established for temporary differences existing at the time of the termination
of the S Corporation election.

The components of the provision for income taxes are as follows:

NOTE 14.  COMMITMENTS AND CONTINGENCIES

The Company has employment agreements with certain key executives. The terms
extend for periods of three to five years.

Although the Company has never had any product liability claims resulting from
failure of a spare part sold or repaired by it, there is no guarantee that the
Company could not be subject to liability from its potential exposure relating
to faulty aircraft parts in the future. The Company maintains liability
insurance with coverage it believes to be in sufficient amounts and on terms
that are generally consistent with industry practice, but there can be no
assurance that such coverage will be adequate to fully protect the Company from
any liabilities it might incur. An uninsured or partially insured loss could
have a material adverse effect upon the Company's financial condition.

NOTE 15.  STOCK OPTION PLAN

In February 1998, the Company adopted the 1998 Omnibus Stock Option Plan (the
"Option Plan"). An aggregate of 450,000 shares of common stock are reserved for
issuance under the Option Plan. During 1998, the Company granted stock options
to individuals who are employees, directors or consultants of the Company
totaling 393,250 shares. The options have an exercise price ranging from $6.00
to $6.60 per share, with a weighted average exercise price of $6.18 per share.
Options for 89,400 shares having a weighted average exercise price of $6.00 per
share are vested as of December 31, 1998, with the remaining options vesting
over four years. The options have terms of between five and ten years. No
options were exercised during the year.

The Company applies APB Opinion 25 and related interpretations in accounting
for its Option Plan. Accordingly, no compensation expense has been recognized.
Had compensation expense been determined based on the fair value at the grant
dates for awards under the Option Plan consistent with the methodology of SFAS
No. 123, the Company's 1998 pro forma net income and earnings per share would
have been reduced to the amounts indicated below. No compensation expense would
be recognized related to the options issued to consultants as these options
represent an expense of the Offering and as such are accounted for as a
reduction of proceeds from the Offering.

                                                                     BASED ON
                                      AS REPORTED                  SFAS NO. 123
                                      -----------                  ------------

Pro forma net income                  $4,194,057                     $3,989,023

Pro forma basic earnings
 per share                                 $0.76                          $0.72

Pro forma diluted earnings 
 per share                                 $0.76                          $0.72

For purposes of determining compensation expense under SFAS 123, the fair value
of each option is measured on the grant date using the Black-Scholes
option-pricing model with the following weighted-average assumptions for the
options granted in 1998: dividend yield of 0 percent; expected volatility of 55
percent; risk-free interest rate of 5.2 percent; and expected life of 7 years.

The weighted average fair value of options granted during 1998 was $3.65.

NOTE 16.  EMPLOYEE BENEFIT PLANS

The Company has a 401(k) profit sharing plan that covers substantially all of
its employees. Employees who have completed more than one year of service and
are over the age of 21 may contribute from 1% to 15% of their base pay. The
Company match on the 401(k) portion is discretionary up to 100% of
contributions up to 6% of eligible salaries. The profit sharing contribution by
the Company is also discretionary. The Company made no contribution to the plan
for the 401(k) portion and contributed $58,264 in 1998 and $63,261 in 1997 for
the profit sharing portion.

The Company has a medical reimbursement plan covering substantially all of its
employees that pays up to $500 per quarter per employee for all medical bills
not covered by another group plan. Reimbursement to employees under this plan
for the years ended December 31, 1998 and 1997 were $23,374 and $16,266,
respectively.

NOTE 17.  RELATED PARTY TRANSACTIONS

The Company leases several warehouse and MRO facilities from related parties
under leases expiring at various dates through 2008. Total rent expense under
these operating leases was $137,400 in 1998 and $81,230 in 1997. Minimum lease
payments are summarized in Note 11.

In October 1993, the Company borrowed $200,000 from U.S. Aviation, Inc.
("USAC") related to the balance of the purchase price of aircraft parts
acquired in December 1989. An original former stockholder is a co-founder,
officer and director of USAC. The note bore an interest rate of 7%, payable in
five equal annual installments of principal and interest, with a maturity of
October 1, 1998. The note was secured by inventory and guaranteed by one
existing stockholder. Principal and interest paid on this note during each of
the period ended December 31, 1997 was $48,780. During 1998, the Company paid
the final payment of $48,780.

The Company presently sells inventory owned by USAC, on consignment and remits
payments quarterly to USAC for 60% of the sales price, less any overhaul and
repair costs incurred by the Company necessary to facilitate the sale of the
inventory. Sales on consignment for USAC were $36,788 and $76,959 in 1998 and
1997, respectively.

In July 1993, the Company borrowed $525,000 from an original former
stockholder. The note bore an interest rate of 6%, with interest only payable
at each anniversary date and the note balance payable in full on June 30, 1998.
The note was guaranteed by the other original stockholder. Interest expense
recognized was $7,875 and $31,500 in 1998 and 1997, respectively. The loan and
accrued interest was repaid from the proceeds of the initial public offering.

The Company had historically made distributions to stockholders in amounts
estimated to cover individual tax liabilities on income from the Company in
connection with its S Corporation election. In 1996, the stockholders loaned
back to the Company funds in excess of their tax liabilities. The notes payable
totaling $121,267 bearing an annual interest rate of 8% were paid in full on
June 12, 1998. In December 1997, the Company made distributions to the
stockholders in the amount necessary to fund their anticipated 1997 tax
liabilities. The stockholders loaned back to the Company funds in excess of
110% of their 1996 tax liabilities. The notes payable totaling $810,000 bearing
and annual interest rate of 8% were paid at maturity on April 15, 1998.

NOTE 17.  RELATED PARTY TRANSACTIONS (CONTINUED)

The Company made investments of $50,000 in 1997 and $50,000 in 1996 in
nonpublic companies, were accounted for at cost. The investment made in 1997
was in a company in which a director is a principal. In conjunction with the
initial public offering, these two investments were included as part of the
distributions, in connection with the termination of the Company's
S-Corporation status, to the then existing common stockholders. The investments
were distributed at estimated fair value, which was equivalent to carrying
value, in lieu of an equal portion of cash.

In connection with the acquisition of Condor, the Company had outstanding
accounts payable to related parties of $53,700 at December 31, 1998. The
accounts payable were for amounts owed to the previous owners for certain
deposits which were made prior to the acquisition.

The Company incurred legal expenses of $315,892 in 1998 and $15,985 in 1997
from a law firm in which a director is a partner. A substantial portion of the
1998 expenditures were included as transaction costs relating to the public
offering and as acquisition cost relating to company acquisitions.

at each anniversary of the Employment Agreement. A "triggering event" as defined
below, or the death or disability of the Executive, shall immediately accelerate
and vest all outstanding options. Any additional options in the future shall be
in the discretion of the Compensation Committee.

         In the event of the occurrence of a "triggering event" which shall be
defined to include a (i) change in ownership in one or a series of transactions
of 50% or more of the outstanding shares of the Company, or (ii) merger,
consolidation, reorganization or liquidation of the Company, and following such
triggering event either (i) the Executive elects to terminate this agreement or
(ii) the Executive's services are terminated by the Company or the Executive or
the Executive's duties, authority or responsibilities are substantially
diminished, the Executive shall receive lump sum compensation equal to 2 times
his annual salary and incentive or bonus payments, if any, as shall have been
paid to the Executive during the Company's most recent 12-month period within 30
days of the triggering event. If the total amount of the change of control
compensation were to exceed three (3) times the Executive's base amount (the
average annual taxable compensation of the Executive for the five (5) years
preceding the year in which the change of control occurs), the Company and the
Executive may agree to reduce the lump sum

compensation to be received by Executive in order to avoid the imposition of the
golden parachute tax as provided in the Tax Reform Act of 1984, as amended by
the Tax Return Act of 1986. If the Company fails to pay the sum calculated
hereunder pursuant to a triggering event then the noncompete set forth in
paragraph 11(c) shall be void.

         In the event the Executive is required to hire counsel to negotiate on
his behalf in connection with his termination or resignation from the Company
upon the occurrence of a triggering event, or in order to enforce the rights and
obligations of the Company as provided in this paragraph, the Company shall
reimburse to the Executive all reasonable attorneys' fees which may be expended
by the Executive in seeking to enforce the terms hereof. Such reimbursement
shall be paid every 30 days after the Executive provides copies of invoices from
the Executive's counsel to the Company. However, such invoices may be redacted
to preserve the attorney-client privilege, client confidentiality or work
product.

         6. Expense Reimbursement. The Company will reimburse the Executive, at
least semi-monthly, for all reasonable and necessary expenses, including without
limitation, travel expenses, and reasonable entertainment expenses, incurred by
him in carrying out his duties under this Agreement. The Executive shall present
to the Company each month an account of such expenses in such form as is
reasonably required by the Board of Directors.

         Since the Executive agrees to relocate to Charlotte, North Carolina,
the Company shall reimburse Executive for reasonable relocation costs including
moving expenses for personal possessions and house hunting as well as selling
expenses for selling his home in Weston, Florida, such reimbursement not to
exceed $37,500.00.

         7. Medical and Dental Coverage. Commencing February 8, 1999, the
Executive will be entitled to participate in the Company's employee group
medical and other group insurance programs on the same basis as other executives
of the Company. Any other benefits offered to personnel in the Company similar
to Executive shall also be offered to Executive upon the same terms.

         8. Medical Examination. The Executive agrees to submit himself for
physical examination on one occasion per year as requested by the Company for
the purpose of the Company's obtaining life insurance on the life of the
Executive for the benefit of the Company as may be required; provided, however,
that the Company shall bear the entire cost of such examinations and shall pay
all premiums on any key man life insurance obtained for the benefit of the
Company as beneficiary or with respect to any other designated beneficiary.


<PAGE>   4

         9. Vacation Time. The Executive shall be entitled each year to three
(3) weeks vacation in accordance with the established practices of the Company,
now or hereafter in effect for the executive personnel, during which time the
Executive's compensation shall be paid in full.

         10. Benefits Payable on Disability. If the Executive becomes disabled
from properly performing services hereunder by reason of illness or other
physical or mental incapacity, the Company shall continue to pay the Executive
his then current salary hereunder for the first six (6) months of such
continuous disability commencing with the first date of such disability. In
replacement to the foregoing, the Company intends to provide group disability
insurance which will cover the Executive. If the Company has not obtained such
coverage within 120 days of the Executive's employment, then the Company will
reimburse the Executive for the cost of disability insurance which will provide
not less than 65% of salary as a benefit.

         11. Obligations of Executive During and After Employment.

                  (a) The Executive agrees that during the terms of his
         employment under this Agreement, he will engage in no other business
         activities directly or indirectly, which are competitive with or which
         might place him in a competing position to that of the Company, or any
         affiliated company.

                  (b) The Executive realizes that during the course of his
         employment, Executive will have produced and/or have access to
         confidential business plans, information, business opportunity records,
         notebooks, data, formula, specifications, trade secrets, customer
         lists, account lists and secret inventions and processes of the Company
         and its affiliated companies. Therefore, during or subsequent to his
         employment by the Company, or by an affiliated company, the Executive
         agrees to hold in confidence and not to directly or indirectly disclose
         or use or copy or make lists of any such information, except to the
         extent authorized by the Company in writing. All records, files,
         business plans, documents, equipment and the like, or copies thereof,
         relating to Company's business, or the business of an affiliated
         company, which Executive shall prepare, or use, or come into contact
         with, shall remain the sole property of the Company, or of an
         affiliated company, and shall not be removed from the Company's or the
         affiliated company's premises without its written consent, and shall be
         promptly returned to the Company upon termination of employment with
         the Company and its affiliated companies. The restrictions and
         obligations of Executive set forth in this Section 11(b) shall not
         apply to (i) information that is or becomes generally available and
         known to the industry (other than as a result of a disclosure directly
         or indirectly by Executive); or (ii) information that was known to
         Executive prior to Executive's employment by the Company or its
         predecessor.


<PAGE>   5

                  (c) Because of his employment by the Company, Executive shall
         have access to trade secrets and confidential information about the
         Company, its business plans, its business accounts, its business
         opportunities, its expansion plans into other geographical areas and
         its methods of doing business. Executive agrees that for a period of
         one (1) year after termination (regardless of any longer severance
         payments) or expiration of his employment, he will not, directly or
         indirectly, compete with the Company in its then present aviation
         business.

                  (d) In the event a court of competent jurisdiction finds any
         provision of this Section 11 to be so overbroad as to be unenforceable,
         then such provision shall be reduced in scope by the court, but only to
         the extent deemed necessary by the court to render the provision
         reasonable and enforceable, it being the Executive's intention to
         provide the Company with the broadest protection possible against
         harmful competition.

                  (e) The Company acknowledges and agrees that during the term
         of this Agreement, Executive may, in his discretion, engage in other
         business and investment activities in addition to those contemplated by
         this Agreement, so long as (a) such activities do not violate the terms
         of the noncompete provisions of paragraph 11(c) hereof, and (b)
         notwithstanding such activities, the Executive devotes such time and
         attention to the affairs of the Company as is reasonably necessary to
         discharge his duties under this Employment Agreement.

                  (f) Notwithstanding anything herein to the contrary, nothing
         herein shall prohibit Executive, during the term hereof or during any
         period as to which paragraph 11(c) applies, from owning interests in
         any public company that engages in business competitive with the
         Company if his ownership interest in such company does not exceed two
         (2%) percent of any class of its capital stock.

         12. Termination for Cause by the Company. The Company may, without
liability, terminate the Executive's employment hereunder for cause at any time
upon written notice from the Board of Directors specifying such cause, and
thereafter the Company's obligations hereunder shall cease and terminate;
provided, however, that such written notice shall not be delivered until after
the Board of Directors shall have given the Executive written notice specifying
the conduct alleged to have constituted such cause and the Executive has failed
to cure such conduct, if curable, within fifteen (15) days following receipt of
such notice.


<PAGE>   6

         Grounds for termination "for cause" are one or more of the following:

                  (a) A willful breach of a material duty by the Executive
         during the course of his employment;

                  (b) Habitual neglect of a material duty by the Executive;

                  (c) Fraud on the Company, conviction of a felony involving or
         against the Company, or conviction of a crime of moral turpitude that
         affects the integrity and name of the Company.

         13. Termination by the Executive or the Company Without Cause;
Termination by Executive With Cause.

                  (a) The Executive, without cause, may terminate this Agreement
         upon 90 days prior written notice to the Company. In such event, the
         Executive shall be required to render the services required under this
         Agreement during such 90-day period unless otherwise directed by the
         Board of Directors. Compensation for vacation time not taken by
         Executive shall be paid to the Executive at the date of termination.
         Executive shall be paid for only the ninety (90) day period pursuant to
         normal pay practices and then all obligations regarding pay shall
         cease.

                  (b) The Company, without cause, may terminate this Agreement.
         In such event, the Company shall pay a severance allowance equal to the
         balance of the base salary payable over the term of the contract at
         regular monthly installments unless the parties negotiate a mutually
         acceptable discounted lump sum. No other benefits will be provided once
         this Agreement is terminated. However, if a triggering event as defined
         in paragraph 5 supra occurs within six (6) months of Executive's
         termination without cause, Executive shall be paid the lump sum
         compensation amount due under paragraph 5.

                  (c) The Executive may terminate this Agreement with the
         Company at any time, upon 30 days' written notice and opportunity for
         the Company to remedy any non-compliance, by reason of (i) the
         Company's material failure to perform its duties pursuant to this
         Agreement, or (ii) any material diminishment in the duties and
         responsibilities, working facilities, or compensation as described in
         paragraphs 1, 2, 4 and 5 of this Agreement. In the event of termination
         of this Agreement by the Executive for cause, the Executive shall be
         paid all base salary specified herein for the remaining term of this
         Agreement. The provisions of paragraph 11(c) shall only apply so long
         as Executive is receiving timely payment in accordance with the
         bi-weekly payroll process.


<PAGE>   7

         14. Termination upon Death of Executive. In addition to any other
provision relating to the termination, this Agreement shall terminate upon the
Executive's death. In such event, the Company shall pay a severance allowance
equal to one hundred eighty (180) days' salary to the Executive's estate.

         15. Arbitration. Any controversy, dispute or claim arising out of, or
relating to, this Agreement and/or its interpretation shall, unless resolved by
agreement of the parties, be settled by binding arbitration in Charlotte,
Mecklenburg County, North Carolina, in accordance with the Rules of the American
Arbitration Association then existing. This Agreement to arbitrate shall be
specifically enforceable under the prevailing arbitration law of the State of
North Carolina. The award rendered by the arbitrators shall be final and
judgment may be entered upon the award in any court of the State of North
Carolina having jurisdiction of the matter.

         16.  General Provisions.

                  (a) The Executive's rights and obligations under this
         Agreement shall not be transferrable by assignment or otherwise, nor
         shall Executive's rights be subject to encumbrance or to the claims of
         the Company's creditors. Nothing in this Agreement shall prevent the
         consolidation of the Company with, or its merger into, any other
         corporation, or the sale by the Company of all or substantially all of
         its property or assets.

                  (b) This Agreement and the rights of Executive with respect to
         the benefits of employment referred to herein constitute the entire
         Agreement between the parties hereto in respect of the employment of
         the Executive by the Company and supersede any and all other agreements
         either oral or in writing between the parties hereto with respect to
         the employment of the Executive.

                  (c) The provisions of this Agreement shall be regarded as
         divisible, and if any of said provisions or any part thereof are
         declared invalid or unenforceable by a court of competent jurisdiction
         or in an arbitration proceeding, the validity and enforceability of the
         remainder of such provisions or parts thereof and the applicability
         thereof shall not be affected thereby.

                  (d) This Agreement may not be amended or modified except by a
         written instrument executed by Company and Executive.

                  (e) This Agreement and the rights and obligations hereunder

         State of South Carolina.

                  (f) Executive shall have no duty to mitigate the payment due
         him from Company pursuant to this Agreement and any money earned by
         Executive from other sources after his 


<PAGE>   8

         employment with the Company terminates shall not reduce the amount owed
         him by the Company pursuant to this Agreement.

                  (g) In the event of any proceeding regarding the enforcement
         of any provision of this Agreement to which the Company and the
         Executive are adverse parties, the losing party shall reimburse the

         and disbursements, incurred by the prevailing party in defense or
         prosecution of any such proceeding.

                        MODIFICATION AND WAIVER AGREEMENT


         THIS MODIFICATION AND WAIVER AGREEMENT (the "Agreement") is made and
entered into as of the ____ day of January, 1999 between AMERICAN AIRCARRIERS
SUPPORT, INCORPORATED (the "Borrower") and NATIONSBANK, N.A. (the "Bank").


                              STATEMENT OF PURPOSE

         The Borrower and the Bank are parties to a Loan Agreement (the "Loan
Agreement") dated July 13, 1998. The Bank has agreed to amend the Loan Agreement
and to provide for a limited waiver of the Borrowing Base Agreement as provided
herein.

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties hereto, each to the other, the parties do hereby
agree as follows:

         1. Amendment of Loan Agreement.

                  (a) Section 2.A. is amended to increase the Bank's commitment
         to make Working Capital Loans from $10,000,000 to $15,000,000 and to
         provide that the obligation of the Borrower to repay the Working
         Capital Loans shall be evidenced by the promissory note of the Borrower
         in the form attached hereto as Exhibit A (the "Working Capital Note")
         payable to the order of the Bank.

                  (b) Section 6.B. of the Loan Agreement is hereby amended by
         deleting the same in its entirety and inserting in lieu thereof the
         following:

                           Lease Expenditures. Incur new obligations for the
                  lease or purchase of real or personal property requiring
                  payments in any fiscal year in excess of an aggregate of
                  $250,000.

         2. Waiver. The aircraft engine (the "leased engine") which is the
subject of the lease between Kellstrom and Vasp Airlines (the "Kellstrom
Lease"), which leased engine and Kellstrom Lease is to be acquired by the
Borrower, will be included in the Borrowing Base and not financed under a
separate term note, subject to review and approval by Bank of the Kellstrom
Lease. If the Borrower has not sold the leased engine and Kellstrom Lease by not
later than March 18, 1999, the Borrower shall promptly grant to the Bank a
security interest in the leased engine and an assignment of the Kellstrom Lease
as additional collateral for the obligations of the Borrower to the Bank under
the Loan Agreement, and failure to do so shall constitute an event of default
under the Loan Agreement.

         3. Limited Amendment. This Agreement shall not be deemed (i) to be a
waiver of, or consent to, or a modification or amendment of, any other term or
condition of the Loan Agreement or (ii) to prejudice any right or rights which
the Bank may now have or may have in 


<PAGE>   2

the future under or in connection with the Loan Agreement or any other loan
document or any of the instruments or agreements referred to therein, as the
same may be amended or modified from time to time.

         4. Representations and Warranties of the Borrower. The Borrower
represents and warrants to the Bank as follows:

                  (a) The Borrower has no defenses, offsets or counterclaims
         against the Bank relating to the Loan Agreement, as modified by this
         Agreement; and

                  (b) The Borrower has full power and lawful authority to
         execute and perform this Agreement.

         5. Conditions to Effectiveness. The effectiveness of this Agreement is
subject to receipt by the Bank of the following documents:

                  (a) The favorable opinion of counsel to the Borrower,

         contemplated by this Agreement and in such form as the Bank shall
         reasonably require.

                  (b) A certified copy of resolutions duly adopted by the Board
         of Directors of the Borrower authorizing the execution, delivery and
         performance of this Agreement and the Working Capital Note, in form and
         substance satisfactory to the Bank.

                  (c) This Agreement and the Working Capital Note, each duly
         executed.

this Agreement and the Loan Agreement, the terms of this Agreement shall govern.

         8. Counterparts. This Agreement may be executed in separate
counterparts, and said counterparts taken together shall be deemed to constitute
one and the same instrument. An executed copy of this Agreement delivered by
telecopier shall be intended to have the same effect as an originally executed
copy of this Agreement.

the order of Bank, its successors and assigns, without setoff, at its offices
indicated at the beginning of this Note, or at such other place as may be
designated by Bank, the principal amount of Four Million Three Hundred Thousand
Dollars ($4,300,000.00), or so much thereof as may be advanced from time to time
in immediately available funds, together with interest computed daily on the
outstanding principal balance hereunder, at an annual interest rate, and in
accordance with the payment schedule, indicated below.

1. Rate. The Rate per annum shall be the 90-day LIBOR (London Interbank Offered
Rate), determined on a daily basis, plus the Applicable Margin. The Rate is
established by Bank as an index and may or may not at any time be the best or
lowest rate charged by Bank on any loan.

The initial Applicable Margin shall be 1.25% and shall be subject to adjustment
based on the ratio of Borrower's (x) Consolidated Senior Funded Debt plus
Subordinated Debt to (y) EBITDA (as defined and determined in accordance with
the Loan Agreement). The calculation and any change in the Applicable Margin
shall take place and be applicable as of the last day of the immediately
preceding fiscal quarter.

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the State of North
Carolina; if any higher rate ceiling is lawful, then that higher rate ceiling
shall apply. Any payment in excess of such maximum shall be refunded to Borrower
or credited against principal, at the option of Bank.

2. Accrual Method. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder).

3. Rate Change Date. Any Rate based on a fluctuating index or base rate will
change, unless otherwise provided, each time and as of the date that the index
or base rate changes.

In the event any index is discontinued, Bank shall substitute an index
determined by Bank to be comparable, in its sole discretion.

4. Payment Schedule. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

5. Principal Plus Accrued Interest. For the first three months of the term of
the Note, Borrower shall pay accrued interest only payable on the first day of
each month commencing on December 1, 1998 and continuing through February 1,
1999. Thereafter, principal shall be paid in sixty consecutive equal monthly
installments of $145,000 each, plus accrued interest, commencing on March 1,
1999, and continuing on the same day of each successive month thereafter, with a
final payment of all unpaid principal and accrued interest due on February 1,
2004. If , on any payment date, accrued interest exceeds the installment amount
set forth above, Borrower will also pay such excess as and when billed.

6. Automatic Payment. Borrower has elected to authorize Bank to effect payment
of sums due under this Note by means of debiting Borrower's account number 00000
180 2800. This authorization shall not affect the obligation of Borrower to pay
such sums when due, without notice, if there are insufficient funds in such
account to make such payment in full on the due date thereof, or if Bank fails
to debit the account.

7. Waivers, Consents and Covenants. Borrower, any indorser or guarantor hereof,
or any other party hereto (individually an "Obligor" and collectively
"Obligors") and each of them jointly and severally: (a) waive presentment,
demand, protest, notice of demand, notice of intent to accelerate, notice of
acceleration of maturity, notice of protest, notice of nonpayment, notice of
dishonor, and any other notice required to be given under the law to any Obligor
in connection with the delivery, acceptance, performance, default or enforcement
of this Note, any indorsement or guaranty of this Note, or any other documents
executed in connection with this Note or any other note or other loan documents
now or hereafter executed in connection with any obligation of Borrower to Bank
(the "Loan Documents"); (b) consent to all delays, extensions, renewals or other
modifications of this Note or the Loan Documents, or waivers of any term hereof
or of the Loan Documents, or release or discharge by Bank of any of Obligors, or
release, substitution or exchange of any security for the 


2
<PAGE>   5

payment hereof, or the failure to act on the part of Bank, or any indulgence
shown by Bank (without notice to or further assent from any of Obligors), and
agree that no such action, failure to act or failure to exercise any right or
remedy by Bank shall in any way affect or impair the obligations of any Obligors
or be construed as a waiver by Bank of, or otherwise affect, any of Bank's
rights under this Note, under any indorsement or guaranty of this Note or under
any of the Loan Documents; and (c) agree to pay, on demand, all costs and
expenses of collection or defense of this Note or of any indorsement or guaranty
hereof and/or the enforcement or defense of Bank's rights with respect to, or
the administration, supervision, preservation, or protection of, or realization
upon, any property securing payment hereof, including, without limitation,
reasonable attorney's fees, including fees related to any suit, mediation or
arbitration proceeding, out of court payment agreement, trial, appeal,
bankruptcy proceedings or other proceeding, in such amount as may be determined
reasonable by any arbitrator or court, whichever is applicable.

8. Delinquency Charge. To the extent permitted by law, a delinquency charge may
be imposed in an amount not to exceed four percent (4%) of the unpaid portion of
any payment that is more than fifteen days late. Unless the terms of this Note
call for repayment of the entire balance of this Note (both principal and
interest) in a single payment and not for installments of interest or principal
and interest, the 4% delinquency charge may be imposed not only with respect to
regular installments of principal or interest or principal and interest, but
also with respect to any other payment in default under this Note (other than a
previous delinquency charge), including without limitation, a single payment of
principal due at the maturity of this Note. In the event any installment, or
portion thereof, is not paid in a timely manner, subsequent payments will be
applied first to the past due balance (which shall not include any previous
delinquency charges), specifically to the oldest maturing installment, and a
separate delinquency charge will be imposed for each payment that becomes due
until the default is cured.

9. Events of Default. The following are events of default hereunder: (a) the
failure to pay or perform any obligation, liability or indebtedness of any
Obligor to Bank, or to any affiliate or subsidiary of NationsBank Corporation,
whether under this Note or any Loan Documents, as and when due (whether upon
demand, at maturity or by acceleration); (b) the death of any Obligor (if an
individual); (c) the resignation or withdrawal of any partner or a material
owner/guarantor of Borrower, as determined by Bank in its sole discretion; (d)
the commencement of a proceeding against any Obligor for dissolution or
liquidation, the voluntary or involuntary termination or dissolution of any
Obligor or the merger or consolidation of any Obligor with or into another
entity; (e) the insolvency of, the business failure of, the appointment of a
custodian, trustee, liquidator or receiver for or for any of the property of,
the assignment for the benefit of creditors by, or the filing of a petition
under bankruptcy, insolvency or debtor's relief law or the filing of a petition
for any adjustment of indebtedness, composition or extension by or against any
Obligor; (f) the determination by Bank that any representation or warranty made
to Bank by any Obligor in any Loan Documents or otherwise is or was, when it was
made, untrue or materially misleading; (g) the failure of any Obligor to timely
deliver such financial statements, including tax returns, other statements of
condition or other information, as Bank shall request from time to time; (h) the
entry of a judgment against any Obligor which Bank deems to be of a material
nature, in Bank's sole discretion; (i) the seizure or forfeiture of, or the
issuance of any writ of possession, garnishment or attachment, or any turnover
order for any property of any Obligor; (j) the determination by Bank that a
material adverse change has occurred in the financial condition of any Obligor;
or (k) the failure of Borrower's business to comply with any law or regulation
controlling its operation.

10. Remedies upon Default. Whenever there is a default under this Note (a) the
entire balance outstanding hereunder and all other obligations of any Obligor to
Bank (however acquired or evidenced) shall, at the option of Bank, become
immediately due and payable and any obligation of Bank to permit further
borrowing under this Note shall immediately cease and terminate, and/or (b) to
the extent permitted by law, the Rate of interest on the unpaid principal shall
be increased at Bank's discretion up to the maximum rate allowed by law, or if
none, Bank's Prime Rate plus 3% per annum (the "Default Rate"). The provisions
herein for a Default Rate and a delinquency charge shall not be deemed to extend
the time for any payment hereunder or to constitute a "grace period" giving
Obligors a right to cure any default. At Bank's option, any accrued and unpaid
interest, fees or charges may, for purposes of computing and accruing interest
on a daily basis after the due date of this Note or any installment thereof, be
deemed to be a part of the principal balance, and interest shall accrue on a
daily compounded basis after such date at the Default Rate provided in this Note
until the entire outstanding balance of principal and interest is paid in full.
Upon a default under this Note, Bank is hereby authorized at any time, at its
option and without notice or demand, to set off and charge against any deposit
accounts of any Obligor (as well as any money, instruments, securities,
documents, chattel paper, credits, claims, demands, income and any other
property, rights and interests of any Obligor), which at any time shall come
into the possession or custody or under the control of Bank or any of its
agents, affiliates or correspondents, any and all obligations due hereunder.
Additionally, Bank shall have all rights and remedies available under each of
the Loan Documents, as well as all rights and remedies available at law or in
equity.

11. Non-Waiver. The failure at any time of Bank to exercise any of its options
or any other rights hereunder shall not constitute a waiver thereof, nor shall
it be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by Bank
unless the same shall be in writing, duly signed on behalf of Bank; each such
waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligors to Bank
in any other respect at any other time.

12. Applicable Law, Venue and Jurisdiction. This Note and the rights and
obligations of Borrower and Bank shall be governed by and interpreted in
accordance with the law of the State of North Carolina. In any litigation in
connection with or to enforce this Note or any indorsement or guaranty of this
Note or any Loan Documents, Obligors, and each of them, irrevocably consent to
and confer personal jurisdiction on the courts of the State of North Carolina or
the United States located within the State of North Carolina and expressly waive
any objections as to venue in any such courts. Nothing contained herein shall,
however, prevent Bank from bringing any action or exercising any rights within
any other state or jurisdiction or from obtaining personal jurisdiction by any
other means available under applicable law.

13. Partial Invalidity. The unenforceability or invalidity of any provision of
this Note shall not affect the enforceability or validity of any other provision
herein and the invalidity or unenforceability of any provision of this Note or
of the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as it may apply to other persons or
circumstances.

14. Binding Effect. This Note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successors, assigns, heirs and
personal representatives, provided, however, that no obligations of Borrower or
Obligors hereunder can be assigned without prior written consent of Bank.

15. Controlling Document. To the extent that this Note conflicts with or is in
any way incompatible with any other document related specifically to the loan
evidenced by this Note, this Note shall control over any other such document,
and if this Note does not address an issue, then each other such document shall
control to the extent that it deals most specifically with an issue.

16. ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES HERETO
INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS
INSTRUMENT, AGREEMENT OR DOCUMENT OR ANY RELATED INSTRUMENTS, AGREEMENTS OR
DOCUMENTS, INCLUDING ANY CLAIM BASED ON OR ARISING FROM AN ALLEGED TORT, SHALL

ANY SUCCESSOR THEREOF ("J.A.M.S."), AND THE "SPECIAL RULES" SET FORTH BELOW. IN
THE EVENT OF ANY INCONSISTENCY, THE SPECIAL RULES SHALL CONTROL. JUDGMENT UPON
ANY ARBITRATION AWARD MAY BE ENTERED IN ANY COURT HAVING JURISDICTION. ANY PARTY
TO THIS INSTRUMENT, AGREEMENT OR DOCUMENT MAY BRING AN ACTION, INCLUDING A

CLAIM TO WHICH THIS AGREEMENT APPLIES IN ANY COURT HAVING JURISDICTION OVER SUCH

         B. RESERVATION OF RIGHTS. NOTHING IN THIS ARBITRATION PROVISION SHALL
BE DEEMED TO (I) LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF
LIMITATION OR REPOSE AND ANY WAIVERS CONTAINED IN THIS INSTRUMENT, AGREEMENT OR
DOCUMENT; OR (II) BE A WAIVER BY BANK OF THE PROTECTION AFFORDED TO IT BY 12

AS (BUT NOT LIMITED TO) INJUNCTIVE RELIEF, WRIT OF POSSESSION OR THE APPOINTMENT
OF A RECEIVER. BANK MAY EXERCISE SUCH SELF HELP RIGHTS, FORECLOSE UPON SUCH
PROPERTY, OR OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES BEFORE, DURING OR

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

FOR VALUE RECEIVED, the undersigned Borrower unconditionally (and jointly and
severally, if more than one) promises to pay to the order of Bank, its
successors and assigns, without setoff, at its offices indicated at the
beginning of this Note, or at such other place as may be designated by Bank, the
principal amount of Fifteen Million Dollars ($15,000,000.00), or so much thereof
as may be advanced from time to time in immediately available funds, together
with interest computed daily on the outstanding principal balance hereunder, at
an annual interest rate, and in accordance with the payment schedule, indicated
below.

1. Rate. The Rate shall be the 90-day LIBOR (London Interbank Offered Rate),
plus 2 percent ("Applicable Margin"), per annum. The "Rate" is the fluctuating
rate of interest established by Bank from time to time, at its discretion,
whether or not such rate shall be otherwise published. The Rate is established
by Bank as an index and may or may not at any time be the best or lowest rate
charged by Bank on any loan.

The Rate of the Loan shall also be subject to adjustment based on the Borrower's
Leverage ratio as defined under the Financial Covenants in the Loan Agreement.
The calculation and any change in the Applicable Margin shall take place and be
applicable as of the last day of the immediately preceding fiscal quarter.

</TABLE>

Notwithstanding any provision of this Note, Bank does not intend to charge and
Borrower shall not be required to pay any amount of interest or other charges in
excess of the maximum permitted by the applicable law of the State of North
Carolina; if any higher rate ceiling is lawful, then that higher rate ceiling
shall apply. Any payment in excess of such maximum shall be refunded to Borrower
or credited against principal, at the option of Bank.

2. Accrual Method. Unless otherwise indicated, interest at the Rate set forth
above will be calculated by the 365/360 day method (a daily amount of interest
is computed for a hypothetical year of 360 days; that amount is multiplied by
the actual number of days for which any principal is outstanding hereunder).

3. Rate Change Date. Any Rate based on a fluctuating index or base rate will
change, unless otherwise provided, each time and as of the date that the index
or base rate changes.

In the event any index is discontinued, Bank shall substitute an index
determined by Bank to be comparable, in its sole discretion.

4. Payment Schedule. All payments received hereunder shall be applied first to
the payment of any expense or charges payable hereunder or under any other loan
documents executed in connection with this Note, then to interest due and
payable, with the balance applied to principal, or in such other order as Bank
shall determine at its option.

   Single Principal Payment. Principal shall be paid in full in a single
payment on June 30, 2000. Interest thereon shall be paid monthly, commencing on
February 1, 1999, and continuing on the same day of each successive month
thereafter, with a final payment of all unpaid interest at the stated maturity
of this Note.

5. Revolving Feature. Borrower may borrow, repay and reborrow hereunder at any
time, up to a maximum aggregate amount outstanding at any one time equal to the
principal amount of this Note, provided that Borrower is not in default under
any provision of this Note, any other documents executed in connection with this
Note, or any other note or other loan documents now or hereafter executed in
connection with any other obligation of 


<PAGE>   10

Borrower to Bank, and provided that the borrowings hereunder do not exceed any
borrowing base or other limitation on borrowings by Borrower. Bank shall incur
no liability for its refusal to advance funds based upon its determination that
any conditions of such further advances have not been met. Bank records of the
amounts borrowed from time to time shall be conclusive proof thereof.

   Uncommitted Facility. Borrower acknowledges and agrees that,
notwithstanding any provisions of this Note or any other documents executed in
connection with this Note, Bank has no obligation to make any advance, and that
all advances are at the sole discretion of Bank.

6. Automatic Payment. Borrower has elected to authorize Bank to effect payment
of sums due under this Note by means of debiting Borrower's account number
_______________________________. This authorization shall not affect the
obligation of Borrower to pay such sums when due, without notice, if there are
insufficient funds in such account to make such payment in full on the due date
thereof, or if Bank fails to debit the account.

7. Waivers, Consents and Covenants. Borrower, any indorser or guarantor hereof,
or any other party hereto (individually an "Obligor" and collectively
"Obligors") and each of them jointly and severally: (a) waive presentment,
demand, protest, notice of demand, notice of intent to accelerate, notice of
acceleration of maturity, notice of protest, notice of nonpayment, notice of
dishonor, and any other notice required to be given under the law to any Obligor
in connection with the delivery, acceptance, performance, default or enforcement

executed in connection with this Note or any other note or other loan documents
now or hereafter executed in connection with any obligation of Borrower to Bank
(the "Loan Documents"); (b) consent to all delays, extensions, renewals or other
modifications of this Note or the Loan Documents, or waivers of any term hereof
or of the Loan Documents, or release or discharge by Bank of any of Obligors, or
release, substitution or exchange of any security for the payment hereof, or the
failure to act on the part of Bank, or any indulgence shown by Bank (without
notice to or further assent from any of Obligors), and agree that no such
action, failure to act or failure to exercise any right or remedy by Bank shall
in any way affect or impair the obligations of any Obligors or be construed as a
waiver by Bank of, or otherwise affect, any of Bank's rights under this Note,
under any indorsement or guaranty of this Note or under any of the Loan
Documents; and (c) agree to pay, on demand, all costs and expenses of collection
or defense of this Note or of any indorsement or guaranty hereof and/or the
enforcement or defense of Bank's rights with respect to, or the administration,
supervision, preservation, or protection of, or realization upon, any property
securing payment hereof, including, without limitation, reasonable attorney's
fees, including fees related to any suit, mediation or arbitration proceeding,
out of court payment agreement, trial, appeal, bankruptcy proceedings or other
proceeding, in such amount as may be determined reasonable by any arbitrator or
court, whichever is applicable.

8. Delinquency Charge. To the extent permitted by law, a delinquency charge may
be imposed in an amount not to exceed four percent (4%) of the unpaid portion of
any payment that is more than fifteen days late. Unless the terms of this Note
call for repayment of the entire balance of this Note (both principal and
interest) in a single payment and not for installments of interest or principal
and interest, the 4% delinquency charge may be imposed not only with respect to
regular installments of principal or interest or principal and interest, but
also with respect to any other payment in default under this Note (other than a
previous delinquency charge), including without limitation, a single payment of
principal due at the maturity of this Note. In the event any installment, or
portion thereof, is not paid in a timely manner, subsequent payments will be
applied first to the past due balance (which shall not include any previous
delinquency charges), specifically to the oldest maturing installment, and a
separate delinquency charge will be imposed for each payment that becomes due
until the default is cured.

9. Events of Default. The following are events of default hereunder: (a) the
failure to pay or perform any obligation, liability or indebtedness of any
Obligor to Bank, or to any affiliate or subsidiary of NationsBank Corporation,
whether under this Note or any Loan Documents, as and when due (whether upon
demand, at maturity or by acceleration); (b) the death of any Obligor (if an
individual); (c) the resignation or withdrawal of any partner or a material
owner/guarantor of Borrower, as determined by Bank in its sole discretion; (d)
the commencement of a proceeding against any Obligor for dissolution or
liquidation, the voluntary or involuntary termination or dissolution of any
Obligor or the merger or consolidation of any Obligor with or into another
entity; (e) the insolvency of, the business failure of, the appointment of a
custodian, trustee, liquidator or receiver for or for any of the property of,
the assignment for the benefit of creditors by, or the filing of a petition
under bankruptcy, insolvency or debtor's relief law or the filing of a petition
for any adjustment of indebtedness, composition or extension by or against any
Obligor; (f) the determination by Bank that any representation or warranty made
to Bank by any Obligor in any Loan Documents or otherwise is or was, when it was
made, untrue or materially misleading; (g) the failure of any Obligor to timely
deliver such financial statements, including tax returns, other statements of
condition or other information, as Bank shall request from time to time; (h) the
entry of a judgment against any Obligor which Bank deems to be of a material
nature, in Bank's sole discretion; (i) the seizure or forfeiture of, or the
issuance of any writ of possession, garnishment or attachment, or any turnover
order for any property of any Obligor; (j) the determination by Bank that a
material adverse change has occurred in the financial condition of any Obligor;
or (k) the failure of Borrower's business to comply with any law or regulation
controlling its operation.

10. Remedies upon Default. Whenever there is a default under this Note (a) the
entire balance outstanding hereunder and all other obligations of any Obligor to
Bank (however acquired or evidenced) shall, at the option of Bank, become
immediately due and payable and any obligation of Bank to permit further
borrowing under this Note shall immediately cease and terminate, and/or (b) to
the extent permitted by law, the Rate of interest on the unpaid principal shall
be increased at Bank's discretion up to the maximum rate allowed by law, or if
none, Prime plus 3% per annum (the "Default Rate"). The provisions herein for a
Default Rate and a delinquency charge shall not be deemed to extend the time for
any payment hereunder or to constitute a "grace period" giving Obligors a right
to cure any default. At Bank's option, any accrued and unpaid interest, fees or
charges may, for purposes of computing and accruing interest on a daily basis
after the due date of this Note or any installment thereof, be deemed to be a
part of the principal balance, and interest shall accrue on a daily compounded
basis after such date at the Default Rate provided in this Note until the entire
outstanding balance of principal and interest is paid in full. Upon a default
under this Note, Bank is hereby authorized at any time, at its option and
without notice or demand, to set off and charge against any deposit accounts of
any Obligor (as well as any money, instruments, securities, documents, chattel
paper, credits, claims, demands, income and any other property, rights and
interests of any Obligor), which at any time shall come into the possession or
custody or under the control of Bank or any of its agents, affiliates or
correspondents, any and all obligations due hereunder. Additionally, Bank shall
have all rights and remedies available under each of the Loan Documents, as well
as all rights and remedies available at law or in equity.

11. Non-Waiver. The failure at any time of Bank to exercise any of its options
or any other rights hereunder shall not constitute a waiver thereof, nor shall
it be a bar to the exercise of any of its options or rights at a later date. All
rights and remedies of Bank shall be cumulative and may be pursued singly,
successively or together, at the option of Bank. The acceptance by Bank of any
partial payment shall not constitute a waiver of any default or of any of Bank's
rights under this Note. No waiver of any of its rights hereunder, and no
modification or amendment of this Note, shall be deemed to be made by 


<PAGE>   11

Bank unless the same shall be in writing, duly signed on behalf of Bank; each
such waiver shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Bank or the obligations of Obligors to Bank
in any other respect at any other time.

12. Applicable Law, Venue and Jurisdiction. This Note and the rights and
obligations of Borrower and Bank shall be governed by and interpreted in
accordance with the law of the State of North Carolina. In any litigation in
connection with or to enforce this Note or any indorsement or guaranty of this
Note or any Loan Documents, Obligors, and each of them, irrevocably consent to
and confer personal jurisdiction on the courts of the State of North Carolina or
the United States located within the State of North Carolina and expressly waive
any objections as to venue in any such courts. Nothing contained herein shall,
however, prevent Bank from bringing any action or exercising any rights within
any other state or jurisdiction or from obtaining personal jurisdiction by any
other means available under applicable law.

13. Partial Invalidity. The unenforceability or invalidity of any provision of
this Note shall not affect the enforceability or validity of any other provision
herein and the invalidity or unenforceability of any provision of this Note or
of the Loan Documents to any person or circumstance shall not affect the
enforceability or validity of such provision as it may apply to other persons or
circumstances.

14. Binding Effect. This Note shall be binding upon and inure to the benefit of
Borrower, Obligors and Bank and their respective successors, assigns, heirs and
personal representatives, provided, however, that no obligations of Borrower or
Obligors hereunder can be assigned without prior written consent of Bank.

15. Controlling Document. To the extent that this Note conflicts with or is in
any way incompatible with any other document related specifically to the loan
evidenced by this Note, this Note shall control over any other such document,
and if this Note does not address an issue, then each other such document shall
control to the extent that it deals most specifically with an issue.

16. ARBITRATION. ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES HERETO
INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS
INSTRUMENT, AGREEMENT OR DOCUMENT OR ANY RELATED INSTRUMENTS, AGREEMENTS OR
DOCUMENTS, INCLUDING ANY CLAIM BASED ON OR ARISING FROM AN ALLEGED TORT, SHALL

ANY ARBITRATION AWARD MAY BE ENTERED IN ANY COURT HAVING JURISDICTION. ANY PARTY
TO THIS INSTRUMENT, AGREEMENT OR DOCUMENT MAY BRING AN ACTION, INCLUDING A
SUMMARY OR EXPEDITED PROCEEDING, TO COMPEL ARBITRATION OF ANY CONTROVERSY OR
CLAIM TO WHICH THIS AGREEMENT APPLIES IN ANY COURT HAVING JURISDICTION OVER SUCH

         B. RESERVATION OF RIGHTS. NOTHING IN THIS ARBITRATION PROVISION SHALL
BE DEEMED TO (I) LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF
LIMITATION OR REPOSE AND ANY WAIVERS CONTAINED IN THIS INSTRUMENT, AGREEMENT OR
DOCUMENT; OR (II) BE A WAIVER BY BANK OF THE PROTECTION AFFORDED TO IT BY 12
U.S.C. SEC. 91 OR ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR (III) LIMIT THE
RIGHT OF BANK HERETO (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT LIMITED

AS (BUT NOT LIMITED TO) INJUNCTIVE RELIEF, WRIT OF POSSESSION OR THE APPOINTMENT
OF A RECEIVER. BANK MAY EXERCISE SUCH SELF HELP RIGHTS, FORECLOSE UPON SUCH
PROPERTY, OR OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES BEFORE, DURING OR

entered into as of the 3rd day of March, 1999 between AMERICAN AIRCARRIERS
SUPPORT, INCORPORATED (the "Borrower") and NATIONSBANK, N.A. (the "Bank").


                              STATEMENT OF PURPOSE

         The Borrower and the Bank are parties to a Loan Agreement dated July
13, 1998 (as heretofore amended, the "Loan Agreement"). The Bank has agreed to
further amend the Loan Agreement as provided herein.

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties hereto, each to the other, the parties do hereby
agree as follows:

         1. Amendment of Loan Agreement.

         (a) Section 1 of the Loan Agreement is amended by inserting the
following definitions in proper alphabetical order:

                  EBITDA. EBITDA means, for any period, (a) net income of the
         Borrower for such period plus (b) the sum of the following, to the
         extent deducted in the determination of net income: (i) interest
         expense, (ii) income and franchise taxes and (iii) amortization,
         depreciation and other non-cash charges (including amortization of good
         will and other intangible assets), all determined in conformity with
         GAAP.

                  Senior Funded Debt. Senior Funded Debt means, with respect to
         the Borrower at any date and without duplication, the sum of the
         following calculated in accordance with GAAP: (a) all liabilities,
         obligations and indebtedness for borrowed money (other than
         Subordinated Debt) including but not limited to obligations evidenced
         by bonds, debentures, notes or other similar instruments of the
         Borrower, (b) all obligations to pay the deferred purchase price of
         property or services of the Borrower, except trade payables arising in
         the ordinary course of business, (c) all obligations of the Borrower as
         lessee under capital leases, (d) all indebtedness of any other Person
         secured by a lien on any asset of the Borrower, (e) all contingent
         obligations of the Borrower, (f) all obligations, contingent or
         otherwise, of the Borrower relative to the face amount of letters of
         credit, whether or not drawn, and banker's acceptances issued for the
         account of the Borrower and (g) all obligations incurred by the
         Borrower pursuant to Hedging Agreements.


<PAGE>   2

                  Subordinated Debt. Subordinated Debt means all indebtedness of
         the Borrower, the repayment of which is subordinated to the obligations
         of the Borrower under this Agreement in form and manner satisfactory to
         the Bank.

         (b) Section 5.A(i) is hereby amended by deleting the same in its
entirety and inserting in lieu thereof the following:

                  Maintain maximum Senior Funded Debt (determined on a
         consolidated basis for the Borrower and its consolidated subsidiaries)
         plus Subordinated Debt to trailing four quarters EBITDA of less than
         4.0 to 1.0 at all times prior to June 1, 1999 and 3.50 to 1.0 at all
         times thereafter.

         2. Amendment of Acquisition Loan Notes. Commencement of the
amortization of the principal balance of the Borrower's Promissory Note dated
November 16, 1998 in the principal amount of $8,700,000 shall be deferred from
March 1, 1999 to May 1, 1999, and commencement of the amortization of the
principal balance of the Borrower's Promissory Note dated December 7, 1998 in
the principal amount of $4,300,000 shall be deferred from April 1, 1999 to June
1, 1999.

         3. Limited Amendment. This Agreement shall not be deemed (i) to be a
waiver of, or consent to, or a modification or amendment of, any other term or
condition of the Loan Agreement or (ii) to prejudice any right or rights which
the Bank may now have or may have in the future under or in connection with the
Loan Agreement or any other loan document or any of the instruments or
agreements referred to therein, as the same may be amended or modified from time
to time.

         4. Representations and Warranties of the Borrower. The Borrower
represents and warrants to the Bank as follows:

                  (a) The Borrower has no defenses, offsets or counterclaims
         against the Bank relating to the Loan Agreement, as modified by this
         Agreement; and

                  (b) The Borrower has full power and lawful authority to
         execute and perform this Agreement.

                           a ____________________________________ corporation,

hereinafter called "Tenant";



                              W I T N E S S E T H:



         In consideration of the mutual covenants and agreements contained
herein, the parties agree for themselves, their successors, and assigns, as
follows:

         1. Description of Premises; Purpose. Landlord hereby leases to Tenant,
and Tenant hereby accepts and rents from Landlord, the Premises located in the
Building (as those terms are defined in the Basic Lease Information), together
with the nonexclusive right to use all parking areas, driveways, sidewalks and
other common facilities furnished by Landlord from time to time in the Building
or on the Land for the common use of tenants in the Building. The Premises are
designated on the building plan attached hereto as Exhibit B. Tenant shall use
the Premises for its Tenant Operations only and for no other purpose.

         2. Lease Term. The term of this Lease (the "Lease Term") shall commence
on the Lease Execution Date and shall end at midnight on the Expiration Date,
unless extended by the exercise of the following option to renew. Tenant is
hereby granted an option to renew and extend the Lease Term for one (1)
additional period of five (5) years (the "Renewal Term") commencing on the
initial Expiration Date. Tenant may exercise its option to renew only if it is
not in default hereunder and only by giving Landlord written notice of such
exercise not less than one hundred eighty (180) days prior to the initial
Expiration Date. The foregoing renewal rights may be execised only by the
original Tenant and shall not inure to the benefit of any assignee, subtenant or
other transferee of the original Tenant. All of the terms and conditions hereof
shall apply during the Renewal Term except that (i) Tenant shall have no further
right to renew this Lease beyond the Renewal Term and (ii) Landlord shall have
no obligation to perform any work or improvements in or in respect of the
Premises.

         3. Construction and Acceptance of Premises.

         (a) Landlord shall proceed to construct improvements upon the Premises
in compliance with the "Description of Landlord's Work" in Exhibit C attached
hereto, with such minor variations as Landlord may deem advisable, and shall
tender the Premises to Tenant. The Premises shall be deemed to be "Ready for
Occupancy" when Landlord has substantially completed Landlord's Work, as
described in Exhibit C and obtained a Certificate of Occupancy from the
appropriate governmental authority. If the Premises are not Ready for Occupancy
prior to the Occupancy Date that is set forth in the Basic Lease Information,
Landlord shall not be deemed to be in default hereunder or otherwise liable in
damages to Tenant, nor shall the Lease Term be affected (other than as set forth
in Paragraph 3(c) herein), except that if for any reason (other than delays
caused by Tenant and Tenant's agents, employees, contractors, subcontractors or
licensees (collectively, "Tenant Delay Factors"), including, without limitation,
change orders requested by Tenant relative to the Description of Landlord's
Work) the Premises are not Ready for Occupancy within six (6) months following
the Occupancy Date that is set forth in the Basic Lease Information (provided
such six-(6) month period shall be extended relative to any delays 


4
<PAGE>   5

in getting the Premises Ready for Occupancy resulting from Force Majeure
Matters, as defined herein), Tenant may, at its option, terminate this Lease by
written notice to Landlord delivered within thirty (30) days following the
expiration of such six-(6) month period, in which event neither party shall have
any further liabilities or obligations hereunder, except Landlord shall repay to
Tenant any prepaid rent (including the Advance Rental Payment, as defined
herein) or Security Deposit (as defined herein) and all indemnification
obligations herein shall survive such termination. Time is of the essence
relative to Tenant's right to terminate this Lease pursuant to this Paragraph
3(a). When the Premises are Ready for Occupancy, Tenant agrees to accept
possession thereof By accepting possession of the Premises, Tenant shall be
deemed to have accepted the same and to have acknowledged that the same fully
comply with Landlord's covenants and obligations hereunder. Tenant further
agrees that, if requested by Landlord, Tenant will furnish Landlord with a
written statement that Tenant has accepted the Premises and that Landlord has
fully complied with Landlord's covenants and obligations hereunder.

         (b) If any Tenant Work is specified in Exhibit C, Tenant agrees to
proceed with due diligence to perform the work described under "Description of
Tenant's Work" in Exhibit C, all of such work to be performed in a good and
workmanlike manner, using new materials, in accordance with plans and
specifications approved by Landlord and in compliance with Exhibit C, and to
install Tenant's fixtures, furniture and equipment in the Premises. Any Tenant
Work or any other work in or with respect to the Premises performed by Tenant in
the future causing venting, opening, sealing, waterproofing or any altering of
the roof of the Building shall be performed by Landlord's roofing contractor at
Tenant's expense. Tenant shall provide Landlord with a certificate from
Landlord's roofing contractor that all such work causing venting, opening,
sealing, waterproofing or in any way altering the roof of the Building has been
performed properly. Tenant hereby holds Landlord harmless from any damage to the
Premises resulting, directly or indirectly, from Tenant's venting, opening,
sealing, waterproofing or in any other way altering the roof of the Building
unless such a certificate from Landlord's roofing contractor was delivered to
Landlord contemporaneously with the completion of such work. In the event of any
dispute as to work performed or required to be performed by Landlord or Tenant,
the certificate of Landlord's architect or engineer shall be conclusive.

         (c) In the event the Premises shall be Ready for Occupancy (as defined
in Paragraph 3(a) herein) prior to the Occupancy Date that is set forth in the
Basic Lease Information, the Occupancy Date shall be the earlier of (i) the date
that is set forth as the Occupancy Date in the Basic Lease Information or (ii)
the date that Tenant occupies the Premises. In the event of a delay in the
completion of Landlord's Work beyond the Occupancy Date that is set forth in the
Basic Lease Information (as contemplated in Paragraph 3(a) herein), the term
"Occupancy Date" herein shall automatically be modified to become the actual
date the Premises shall become Ready for Occupancy and the Expiration Date shall
automatically be modified on a consistent basis (i.e., to afford the full Lease
Term, as defined in the Basic Lease Information). Provided, however, and
notwithstanding the foregoing terms and provisions to the contrary, if and to
the extent the Premises are not Ready for Occupancy on or before the Occupancy
Date set forth in the Basic Lease Information as a result of one or more Tenant
Delay Factors, there shall be no adjustment in the Occupancy Date and the
Expiration Date that are set forth in the Basic Lease Information.

         4. Annual Rental. From and after January 1, 1999, and during the full
Lease Term (as the same may be extended), Tenant shall pay to Landlord, without
notice, demand, reduction, setoff or any defense, a total annual rental (the
"Annual Rental") consisting of the sum total of the Minimum Rental and Tenant's
Proportionate Share (as said terms are defined herein) of taxes, insurance
premiums and common area maintenance costs (provided, however, as set forth in
the Basic Lease Information, payment of Minimum Rental shall not commence until
the Rent Commencement Date).

         (a) Minimum Rental. For the period from the Rent Commencement Date
through the Expiration Date, as the same may be extended pursuant to Paragraph
2, Tenant shall pay a minimum rental (the "Minimum Rental") at the annual rates
set forth below, in equal monthly installments, in advance on the Rent
Commencement Date and on the first day of each month thereafter during the
remainder of the Lease Term. Minimum Rental for any parital calendar month shall
be prorated on a per diem basis.

                  (i) From April 15, 1999, (the Rent Commencement Date) through
December 31, 2000, Tenant shall pay Minimum Rental at the annual rate of Three
Hundred Forty-Seven Thousand Thirty-Five and 95/00 Dollars ($347,035.95), in
equal monthly installments of Twenty-Eight Thousand Nine Hundred Nineteen
Thousand and 66/100 Dollars ($28,919.66) each.

                  (ii) From January 1, 2001, through December 31, 2002, Tenant
shall pay Minimum Rental at the annual rate of Three Hundred Sixty-One Thousand
Six Hundred Forty-Seven and 99/100 Dollars ($361,647.99), in equal monthly
installments of Thirty Thousand One Hundred Thirty-Seven and 33/100 Dollars
($30,127.33) each.

                  (iii) From January 1, 2003, through December 31, 2003, Tenant
shall pay Minimum Rental at the annual rate of Three Hundred Seventy-Five
Thousand Forty-Two and 36/100 Dollars ($375,042.36), in equal monthly
installments of Thirty-One Thousand Two Hundred Fifty-Three and 53/100 Dollars
($31,253.53) each.

                  (iv) During the first year of the Renewal Term (from January
1, 2004, through December 31, 2004), if any, Tenant shall pay Minimum Rental at
the annual rate of Three Hundred Eighty-Two Thousand Three Hundred Forty-Eight
and 38/100 Dollars ($382,348.38), in equal monthly installments of Thirty-One
Thousand Eight Hundred Sixty-Two and 37/100 Dollars ($31,862.37) each.

                  (v) On January 1, 2005, and on January 1 of each successive
calendar year during the Renewal Term, if any, the Minimum Rental shall be
increased by two percent (2%) of the Minimum Rental payable during the next
preceding calendar year.

         (b) [Intentionally deleted].

         (c) Tenant's Proportionate Share. "Tenant's Proportionate Share" of the
taxes, of the insurance premiums and of common area maintenance costs (including
any assessment by a property owner's association), as described herein, shall be
determined by multiplying each such amount by a fraction, the numerator of which
is the total square footage of space in the Premises and the denominator of
which is the total square footage of space in the Building.

                  (1) Tenant's Proportionate Share of Taxes. Tenant shall pay an
         amount equal to Tenant's Proportionate Share of any ad valorem taxes
         (or any tax hereafter imposed in lieu thereof) payable for the Building
         relative to the Lease Term. Tenant's Proportionate Share of taxes shall
         be paid as provided in Paragraph 4(d) herein. Anything contained herein
         to the contrary notwithstanding, any increase in ad valorem taxes on
         the Premises as a result of alterations, additions or improvements made
         by, for or on account of Tenant shall be reimbursed entirely by Tenant
         to Landlord (as additional rent hereunder) within thirty (30) days
         after Tenant's receipt of written demand therefor.

                  (2) Tenant's Proportionate Share of Insurance Premiums. Tenant
         shall pay an amount equal to Tenant's Proportionate Share of any amount
         of premiums charged for fire and extended coverage and liability
         insurance, together with all endorsements thereto, carried by Landlord
         on the Building relative to the Lease Term. Tenant's Proportionate
         Share of insurance premiums shall be paid as provided in Paragraph 4(d)
         herein.

                  (3) Tenant's Proportionate Share of Common Area Maintenance
         Costs. Tenant shall pay an amount equal to Tenant's Proportionate Share
         of the costs of maintaining the Building's common areas (as designated
         from time to time by Landlord for the common use of tenants of the
         Building) relative to the Lease Term. Common area maintenance costs
         shall include, but are not limited to, the cost of grass mowing, shrub
         care and general landscaping (including irrigation); the cost of
         repairing, replacing and maintaining parking areas, driveways,
         sidewalks, exterior lighting, common plumbing, common advertising signs
         and other facilities operated with respect to the Building; the cost of
         providing security for the Building and the Land; the cost of providing
         fire alarm monitoring for the Building; and property management fees
         and expenses. Additionally, if a property owner's association is
         established for the maintenance of the common areas 


6
<PAGE>   7

         of the Center, any property owner's association charges allocated to
         the Land and the Building shall be included in the maintenance costs
         for the Land and the Building, and Tenant shall pay Tenant's
         Proportionate Share thereof. Tenant's Proportionate Share of common
         area maintenance costs shall be paid as provided in Paragraph 4(d)
         herein. Landlord shall use good faith efforts to keep the operating and
         maintenance costs in line with costs for other similarly situated first
         class centers. Tenant, at its expense, shall provide its own garbage
         collection, recycling and disposal.

         (d) Payment of Tenant's Proportionate Share. The estimated amounts of
Tenant's Proportionate Share for taxes, insurance premiums and common area
maintenance costs for the calendar year in which the Rent Commencement Date
(i.e., the Rent Commencement Date that is set forth in the Basic Lease
Information) falls are set forth in the Basic Lease Information. For each
succeeding calendar year during the Lease Term, Landlord shall submit an
estimate of Tenant's Proportionate Share for taxes, insurance premiums and
common area maintenance costs on or before April 1 of each such succeeding
calendar year. If an estimate of Tenant's Proportionate Share of expenses for
any calendar year during the Lease Term has not been submitted on or before the
first day of any month in such calendar year, Tenant shall pay Tenant's
Proportionate Share for such month(s) at the estimated rate for the previous
calendar year, and such payment(s) shall be adjusted effective as of January 1
of such calendar year at such time as the estimate for such calendar year is
submitted, at which time the deficiency or overage (as the case may be) in the
estimated payments for the preceding months in such calendar year also shall be
collected or credited (as the case may be). Landlord shall charge, and Tenant
shall pay, the estimated Tenant's Proportionate Share of expenses on a monthly
basis or on some other periodic basis established by Landlord, payable in
advance and subject to adjustment after the end of the respective calendar year
on the basis of the actual costs incurred for such calendar year. Tenant's
Proportionate Share of estimated taxes, insurance premiums and common area
maintenance costs shall be paid in a like manner, with the monthly rental
installments being adjusted accordingly. In the event such costs actually
decrease for any such calendar year, Landlord shall reimburse Tenant for any
overage paid and the monthly rental installments for the next period shall be
reduced accordingly (but in no event below the then-current Minimum Rental).
Upon the Expiration Date of this Lease, Landlord may elect to either (i) require
Tenant to pay any unpaid estimated Tenant's Proportionate Share within thirty
(30) days after the Expiration Date, which estimate shall be made by Landlord
based upon actual and estimated costs for such year, or (ii) elect to withhold
Tenant's Security Deposit until the exact amount of Tenant's Proportionate Share
shall have been determined and paid, after which Landlord shall return any
excess Security Deposit to Tenant.

         (e) Late Charge. If Tenant should fail to pay to Landlord when due any
installment of Annual Rental or other sum to be paid hereunder, Tenant shall pay
Landlord on demand a late charge of four percent (4%) of the amount due. Failure
to pay such late charge upon demand therefor shall be an Event of Default (as
defined herein) hereunder. Provision for such late charge shall be in addition
to all other rights and remedies available to Landlord hereunder or at law or in
equity and shall not be construed as liquidated damages or as limiting
Landlord's remedies in any manner, and such late charge shall accrue
automatically, regardless of whether Landlord shall have given Tenant written
notice of any such delay in payment.

         5. Alterations and Improvements by Tenant. Any structural changes or
other material alterations, additions, or improvements made to the Premises by
Tenant shall be subject to the prior written consent of Landlord and shall be at
the sole cost and expense of Tenant. All such alterations, additions or
improvements shall be constructed in a good and workmanlike manner, using new
materials, in accordance with plans and specifications approved by Landlord and
in compliance with the terms of Paragraph 3(b) herein and all Applicable Laws.
As used herein, "Applicable Laws" shall mean all laws, ordinances (including
Fire and Building Codes), regulations, orders, interpretations and zoning
requirements of any governmental authority, agency or other public or private
regulatory authority (including insurance underwriters or rating bureaus) which
may be in effect from time to time and relating to the Tenant Operations, the
Premises or Tenant's business conducted therein. Additionally, Tenant covenants
and agrees that no improvements, changes, alterations, additions, maintenance or
repairs shall be made by Tenant to the Premises which might impair the
structural soundness of the Building, which might result in 


7
<PAGE>   8

an overload of the weight capacity of floors in the Building, which might result
in an overload of capacity of electric lines serving the Building, or which
might interfere with electric or electronic equipment in the Building or on any
adjacent or nearby property. Upon the expiration or earlier termination of this
Lease, all alterations, additions or improvements, including, without
limitation, all walls, railings, carpeting, floor and wall coverings and other
permanent real estate fixtures (excluding, however, Tenant's trade fixtures and
equipment, as described in Paragraph 11 herein) made by, for, or at the
direction of Tenant, and upon the election of Landlord, shall either: (i) become
the property of Landlord and remain upon the Premises or (ii) be removed from
the Premises by Tenant, at Tenant's sole cost and expense.

         6. Use of Premises. Tenant shall use the Premises only for the Tenant
Operations and for no other purpose and shall comply with all Applicable Laws in
connection with the use of the Premises. Tenant shall be responsible for any and
all costs and expenses associated with Tenant's compliance with all Applicable
Laws, including the cost of altering the Premises to comply with Applicable Laws
(including changes therein from time to time). Without limiting the generality
of the foregoing, Tenant shall be responsible, at Tenant's expense, for all
costs of complying with the requirements of the Americans With Disabilities Act
(as amended) (the "ADA"), including costs for alterations, (i) relative to the
Premises and, (ii) to the extent such compliance is required as a result of the
specific use made by Tenant of the Premises, relative to the exterior and common
areas and facilities of the Building. Landlord shall be responsible for
complying with the requirements of the ADA relative to the exterior and common
areas and facilities of the Building in all instances other than where such
compliance is required as a result of the specific use made of space in the
Building by any tenant in the Building. Additionally, Tenant covenants and
agrees that nothing shall be done or kept in the Premises which might result in
an overload of the weight capacity of floors in the Building, which might result
in an overload of capacity of electric lines serving the Building, or which
might interfere with electric or electronic equipment in the Building or on any
adjacent or nearby property. Tenant shall not do any act or follow any practice
relating to the Premises which shall constitute a nuisance or detract in any way
from the reputation of the Center as a first class real estate development.
Tenant's duties in this regard shall include allowing no noxious or offensive
odors, fumes, gases, smoke, dust, steam or vapors, or any loud or disturbing
noise or vibrations to originate in or emit from the Premises. If, within thirty
(30) days of demand therefor by Landlord, Tenant fails, at its expense, to make
any alterations required to be made by Tenant pursuant to this paragraph, then
Landlord shall have the right to make such alterations (including any entry
required in the Premises to make such alterations), and Tenant shall pay to
Landlord (as additional rent hereunder) all costs and expenses incurred by
Landlord relative to such alterations; and such additional rent shall be paid by
Tenant to Landlord within thirty (30) days after demand therefor by Landlord.
Additionally, Tenant shall save Landlord harmless from any penalties, fines,
costs, expenses or damages resulting from Tenant's failure to comply with the
terms and requirements of this paragraph.

         7. Taxes. Tenant shall pay in a timely manner and prior to delinquency
any taxes or assessments of any nature imposed or assessed upon its trade
fixtures, equipment, machinery, inventory, merchandise or other personal
property located on the Premises and owned by or in the custody of Tenant.
Landlord shall pay all ad valorem property taxes which are now or hereafter
assessed upon the Center, the Building and the Premises, except as otherwise
expressly provided in this Lease.

         8. Fire and Extended Coverage Insurance. Landlord shall maintain and
pay for fire insurance, with extended coverage, covering the Building equal to
ninety percent (90%) of the insurable value thereof (i.e., the replacement cost,
less depreciation). Provided, however, if Tenant uses the Premises for any
purpose or in any manner which causes an increase in Landlord's insurance rates,
Tenant shall pay such additional insurance premium (in addition to all other
payments due under this Lease) to Landlord as additional rent within thirty (30)
days after demand from Landlord. Tenant shall maintain and pay for all fire and
extended coverage insurance on its contents in the Premises, including trade
fixtures, equipment, machinery, merchandise or other personal property belonging
to or in the custody of Tenant.

         9. Landlord's Limited Covenant to Repair and Replace. During the Lease
Term, Landlord shall be responsible for repairs or replacements to the roof,
exterior walls and structural members, including foundation and subflooring of
the Premises (except office fronts, plate glass 


8
<PAGE>   9

windows, doors, door closure devices, window and door frames, nailing, locks and
hardware and painting or other treatment of interior and exterior walls, and
except for any repairs and replacements necessitated by an "Event of Tenant
Misconduct" as defined in Paragraph 16(a) herein). Landlord's efforts to repair
and replace pursuant to this paragraph shall be made within a reasonable time
after written notice from Tenant of the need for such repair or replacement to
be made. Without limiting the generality of the foregoing, with respect
particularly to any Emergency Repair, Landlord shall be obligated to commence
repair efforts within five (5) days of its receipt of notice from Tenant of the
need for such Emergency Repair and diligently prosecute such Emergency Repair to
completion ("Landlord's Emergency Repair Obligation"). As used herein,
"Emergency Repair" shall mean any repair which, if made, would cure a condition
having a significant adverse effect on Tenant's operations in the Premises. With
respect to latent or patent defects in the Premises or in the Building,
Landlord's liability shall not extend beyond one year from the date of
substantial completion of the construction of the improvements specified in the
Description of Landlord's Work set forth in Exhibit C hereto, whether or not
such defects are discovered within such one-year period. If Landlord cannot,
using due diligence, complete its repairs and replacements within two hundred
ten (210) days after written notice from Tenant and if the resulting condition
renders a material portion of the Premises untenantable for the Tenant
Operations, then, following the expiration of such two-hundred-ten- (210) day
period and continuing until such time as the repair or replacement is completed
(or is completed sufficiently so as to not render a material portion of the
Premises untenantable for the Tenant Operations), either party may terminate
this Lease effective upon thirty (30) days prior written notice, without
prejudice to Landlord's rights to receive payment from Tenant for uninsured
damages caused directly or indirectly by Tenant as stated below. If the cause of
such repairs or replacements is the result of an Event of Tenant Misconduct,
then Tenant shall not be entitled to terminate this Lease pursuant to this
paragraph, and Tenant shall pay Landlord the full amount of such cost, damage,
and expense (except as otherwise provided in Paragraph 14 herein). Furthermore,
in the event Landlord diligently pursues the completion of the required repairs
and replacements during the two-hundred-ten- (210) day period provided above but
is unable to complete such repairs and replacements prior to the expiration of
such period, such two-hundred-ten- (210) day period shall be extended for all
purposes under this paragraph (including Tenant's termination right) for such
additional, reasonable period of time as is necessary to allow Landlord to
complete such repair or replacement (provided Landlord must continue to pursue
the completion of such repair or replacement in a diligent manner). Landlord's
duty to repair or replace as prescribed in this paragraph shall be Tenant's sole
remedy and shall be in lieu of all other warranties or guaranties of Landlord,
express or implied. Furthermore, the terms of this paragraph shall have no
application to casualty events and exercises of the power of eminent domain that
affect the Building or the Land, which shall be governed by the terms and
provisions in Paragraph 13 herein and Paragraph 18 herein, respectively.

         10. Tenant's Covenant to Repair. Tenant shall be responsible for the
repair, replacement and maintenance in good order and condition of all parts and
components of the Premises, other than those specified for maintenance by
Landlord herein, including, without limitation, the plumbing, wiring, electrical
system, heating system, air conditioning system, glass and plate glass,
equipment and machinery constituting fixtures located within the Premises and
shall keep all plumbing units, pipes and connections free from obstruction and
protected against ice and freezing. At the end of the Lease Term, Tenant shall
return the Premises to Landlord in as good a condition as existed at the time
all of the Landlord's Work and all of the Tenant's Work (if any) was completed
pursuant to Paragraph 3 herein, excepting only normal wear and tear, acts of God
and repairs required to be made by Landlord hereunder. Tenant's duty to maintain
the heating and air conditioning system serving the Premises shall specifically
include the duty to inspect the system, to replace filters as recommended and to
perform other recommended periodic servicing. During the entire Lease Term,
Tenant shall obtain and maintain a service contract with an independent
maintenance contractor reasonably satisfactory to Landlord to provide such
service for the heating and air conditioning system. The service contract must
include all services suggested by the applicable equipment manufacturer(s) in
the operation and maintenance manual(s) and must become effective on the
Occupancy Date. If any repairs required to be made by Tenant hereunder are not
made within thirty (30) days after written notice delivered to Tenant by
Landlord (provided no advance written notice shall be required in cases of
emergency), Landlord may, at its option, make such repairs without liability 


9
<PAGE>   10

to Tenant for any loss or damage which may result to Tenant's stock or business
by reason of such repairs, and Tenant shall pay to Landlord immediately upon
demand, as additional rental hereunder, the cost of such repairs plus ten
percent (10%) of the amount thereof, and failure to do so shall constitute an
Event of Default hereunder.

         11. Trade Fixtures and Equipment; Non-Liability for Certain Damages.

         (a) So long as Tenant is not in default under this Lease, any trade
fixtures and equipment installed in the Premises at Tenant's expense shall
remain Tenant's personal property, and Tenant shall have the right at any time
during the Lease Term to remove such fixtures and equipment. Upon removal of any
fixtures or equipment, Tenant shall immediately restore the Premises to
substantially the same condition as existed at the time all of the Landlord's
Work and all of the Tenant's Work (if any) was completed pursuant to Paragraph 3
herein, ordinary wear and tear and acts of God alone excepted. Any trade
fixtures and equipment not removed by Tenant at the expiration or an earlier
termination of this Lease shall, at Landlord's option, either: (i) become the
property of Landlord or (ii) be removed by Landlord, at Tenant's expense.

         (b) Landlord and Landlord's agents and employees shall not be liable to
Tenant or any other person or entity whomsoever for any injury to person or
damage to property caused by the Premises or other portions of the Center
becoming out of repair or by defect in or failure of equipment, pipes or wiring,
or broken glass, or by the backing up of drains, or by gas, water, steam,
electricity or oil leaking, escaping or flowing into the Premises, nor shall
Landlord be liable to Tenant or any other person or entity whomsoever for any
loss or damage that may be occasioned by or through the acts or omissions of
other tenants of the Center or of any other persons or entities whomsoever,
excepting only duly authorized employees and agents of Landlord. Landlord shall
not be liable to Tenant for any compensation, damages or reduction of rent by
reason of inconvenience or annoyance or loss of business arising from power
losses or shortages or from the necessity of Landlord's entering the Premises
for any of the purposes authorized in this Lease or for repairing the Premises.
Landlord's liability with respect to any defects, repairs or maintenance for
which Landlord is responsible under any provision of this Lease shall be limited
to the cost of such repairs or maintenance or the curing of such defect. Tenant
shall indemnify and hold Landlord harmless from and against any loss, cost,
expense or claims arising out of such injury or damage referred to in this
paragraph.

         12. Utilities. Tenant shall pay in a timely manner and prior to
delinquency for all utilities or services related to its use of the Premises,
including electricity, gas, heat, sewer, water, telephone and janitorial
services. Landlord shall not be responsible for the stoppage or interruption of
utilities services, other than as required by its limited covenant to repair and
replace set forth herein.

         13. Damage or Destruction of Premises. If the Building is so damaged by
fire or other casualty that substantial alteration or reconstruction of the
Building shall be required (whether or not the Premises shall have been damaged
by such casualty) or in the event any mortgagee of Landlord should require that
all or any portion of the insurance proceeds payable as a result of a casualty
be applied to the payment of the underlying mortgage debt, Landlord may, at its
option, terminate this Lease by notifying Tenant in writing of such termination
within sixty (60) days after the date the casualty event occurs. If the Premises
are damaged by fire or other casualty but are not rendered untenantable for
Tenant's business, either in whole or in part, and if Landlord does not
terminate this Lease pursuant to the immediately preceding sentence, Landlord
shall cause such damage to be repaired (to the extent of Landlord's Work)
without unreasonable delay and the Annual Rental shall not be abated. If by
reason of such casualty, the Premises are rendered untenantable for Tenant's
business, either in whole or in part, and Landlord does not terminate this Lease
as provided in the first sentence above in this Paragraph 13, Landlord shall
cause the damage to be repaired or replaced (to the extent of Landlord's Work)
without unreasonable delay, and in the interim, the Annual Rental shall be
equitably reduced as to such portion of the Premises as is rendered
untenantable. Any such abatement of rent shall not, however, create an extension
of the Lease Term. Provided, however, if by reason of such casualty, the
Premises are rendered substantially untenantable, and Landlord fails to give
Tenant reasonable assurances that the amount of time required to repair the
damage, using due diligence, shall not exceed two hundred ten (210) days from
the date the casualty event 


10
<PAGE>   11

occurs, then either party shall have the right to terminate this Lease by giving
written notice of termination within sixty (60) days after the date the casualty
event occurs. Notwithstanding the other provisions of this Paragraph 13, in the
event there is a casualty loss to the Premises to the extent of fifty percent
(50%) or more of the replacement value during the last Lease Year of the Lease
Term, including any extension of the Lease Term that has then been exercised by
Tenant, either party may, at its option, terminate this Lease by giving written
notice within sixty (60) days after the date the casualty event occurs; and, in
such case, rent shall abate as of the later of (i) the date of such termination
notice or (ii) the date that Tenant vacates the Premises (which vacation of the
Premises must occur within thirty (30) days after the date of such termination
notice). Except as provided herein, there shall be no obligation of Landlord to
rebuild or repair in case of fire or other casualty, and no termination under
this Paragraph 13 shall affect any rights of Landlord or Tenant hereunder
because of prior defaults of the other party. Tenant shall give Landlord
immediate notice of any fire or other casualty in the Premises.

         14. Mutual Waiver; Waiver of Subrogation. The parties mutually release
and waive unto the other, all rights to claim damages, costs or expenses for any
injury to persons (including death) or property caused by a casualty of any type
whatsoever in, on or about the Premises, the Building or the Center if the
amount of such damages, costs or expenses either (i) has been paid to such
damaged party under the terms of any policy of insurance or (ii) would have been
paid to such damaged party under the terms of any policy of insurance required
to be carried by such party hereunder if such party had actually procured such
insurance. All insurance policies carried with respect to this Lease, if
permitted under applicable law, shall contain a provision whereby the insurer
waives prior to loss all rights of subrogation against either Landlord or Tenant
(as the case may be).

         15. Signs and Advertising. In order to provide architectural control
for the Center, Tenant may install, at Tenant's expense: only such exterior
signs, marquees, billboards, outside lighting fixtures and/or other decorations
on the Premises as shall have been approved in advance and in writing by
Landlord. The care and maintenance of all such approved signs shall be the sole
responsibility of Tenant. Landlord shall have the right to remove any such sign
or other decoration and fully restore the exterior of the Premises at the cost
and expense of Tenant if any such exterior work is done without Landlord's prior
written approval. Upon the expiration or earlier termination of this Lease,
Tenant shall remove any such sign or decoration and fully restore the exterior
of the Premises, at Tenant's sole cost and expense. Tenant shall not permit,
allow or cause to be used in, on or about the Premises any sound production
devices, mechanical or moving display devices, bright lights, or other
advertising media, the effect of which would be visible or audible from the
exterior of the Premises.

         16. Indemnification, Liability Insurance and Hazardous Substances.

         (a) Indemnification by Tenant. Tenant shall indemnify and save Landlord
harmless against any and all claims, suits, demands, actions, fines, damages and
liabilities and all costs and expenses thereof (including, without limitation,
reasonable attorneys' fees) arising out of injury to persons (including death)
or property occurring in, on or about, or arising out of, the Premises, the
Building or other areas in the Center if caused by or occasioned wholly or in
part by any willful or negligent act or omission of Tenant, its agents,
subtenants, licensees, invitees, contractors, subcontractors or employees
(collectively, an "Event of Tenant Misconduct"). Tenant shall give Landlord
immediate written notice of any such happening causing injury to persons or
property.

         (b) Indemnification by Landlord. Landlord shall indemnify and save
Tenant harmless against any and all claims, suits, demands, actions, fines,
damages and liabilities and all costs and expenses thereof (including, without
limitation, reasonable attorneys' fees) arising out of injury to persons
(including death) or property occurring in, on or about, or arising out of, the
Premises, the Building or other areas in the Center if such damage or injury is
caused by any willful or negligent act or omission of Landlord, its agents or
employees.

         (c) Liability Insurance. At all times during the Lease Term, Tenant
shall, at its own expense, keep in force comprehensive public liability
insurance in such amounts and with such companies as shall, from time to time,
be acceptable to Landlord (and to any mortgagee having a mortgage interest in
the Premises) and naming Landlord as an additional insured. The amounts 


11
<PAGE>   12

of such coverage, until changed at Landlord's request, shall be $1,000,000.00
with respect to bodily injury or death of one person as a result of any one
accident and $500,000.00 with respect to damage to property. Tenant shall first
furnish to Landlord a copy of the required policy or certificate of insurance,
evidencing the required coverage and naming Landlord as an additional insured
under such policy, within five (5) days of the Lease Execution Date and
thereafter prior to each policy renewal date. Such policy also shall include
contractual liability coverage for the performance by Tenant of the indemnity
obligations of Tenant under this Lease, and such policy shall contain a
provision whereby the insurer is not allowed to cancel, fail to renew or
materially change the coverage without first giving thirty (30) days written
notice to Landlord.

         (d) Presence and Use of Hazardous Substances. Tenant shall not, without
Landlord's prior written consent, keep on or around the Premises, the common
areas or facilities in or relating to the Building, the Land, or the Center, for
use, disposal, treatment, generation, storage or sale, any substances designated
as, or containing components designated as, hazardous, dangerous, toxic or
harmful, and/or any substance that is subject to regulation by any then-current
federal, state or local law, statute or ordinance and the rules and regulations
implementing them, including, but not limited to, the Resource Conservation and
Recovery Act (42 U.S.C. ss. 6901 et seq.); the Comprehensive Environmental
Response, Compensation and Liability Act (42 U.S.C. ss. 9601 et seq.); the Clean
Water Act (33 U.S.C. ss. 1251 et seq.); the Clean Air Act (42 U.S.C. ss. 7401 et
seq.); and the Toxic Substances Control Act (15 U.S.C. ss. 2601 et seq.) (such
substances being herein collectively referred to as "Hazardous Substances").
With respect to any such Hazardous Substance, Tenant shall:

                  (1) Comply promptly, timely and completely with all
         governmental requirements for reporting, keeping and submitting
         manifests and obtaining and keeping current identification numbers;

                  (2) Submit to Landlord true and correct copies of all reports,
         manifests and identification numbers at the same time as they are
         required to be and/or are submitted to the appropriate governmental
         authorities;

                  (3) Within five (5) days of Landlord's request from time to
         time, submit written reports to Landlord regarding Tenant's use,
         storage, treatment, transportation, generation, disposal or sale of
         Hazardous Substances and provide evidence satisfactory to Landlord of
         Tenant's compliance with the applicable governmental laws, statutes,
         ordinances, rules, regulations and requirements;

                  (4) Allow Landlord or Landlord's agent or representative to
         enter the Premises at all times to check Tenant's compliance with all
         applicable governmental laws, statutes, ordinances, rules, regulations
         and requirements regarding Hazardous Substances;

                  (5) Comply with minimum levels, standards or other performance
         standards or requirements which may be set forth or established for
         certain Hazardous Substances; and if minimum standards or levels are
         applicable to Hazardous Substances present on the Premises, such
         standards or levels shall be established and documented by an on-site
         inspection by the appropriate governmental authorities and shall be set
         forth in an addendum to this Lease;

                  (6) Comply with all applicable governmental laws, statutes,
         ordinances, rules, regulations and requirements regarding the proper
         and lawful use, sale, transportation, generation, treatment and
         disposal of such Hazardous Substances; and

                  (7) Pay to Landlord upon demand as additional rent any and all
         costs incurred by Landlord and associated with Landlord's inspection of
         the Premises and Landlord's monitoring of Tenant's compliance with this
         Paragraph 16(d), including Landlord's attorneys' fees and costs.

The terms and provisions in this Paragraph 16(d) shall survive the expiration of
the Lease Term or the earlier termination of this Lease.

<PAGE>   13

         (e) Unauthorized Releases of Hazardous Substances; Cleanup Costs;
Default and Indemnification.

                  (1) Tenant shall give immediate written notice to Landlord of
         any release, spill, discharge or threatened discharge of any Hazardous
         Substance on or at the Premises, the common areas or facilities in or
         relating to the Building, the Land, the Center, or the surrounding
         environment, which release, spill, discharge or threatened discharge
         was not made pursuant to or in conformance with the terms of any permit
         or license issued to Tenant by the appropriate governmental authority.
         Such notice shall include a description of measures taken or proposed
         to be taken by Tenant to contain and/or remedy the release, spill,
         discharge or threatened discharge and any resultant damage to property,
         persons, the Premises, the common areas or facilities in or relating to
         the Building, the Land, the Center, and/or the surrounding environment.
         Tenant also shall give immediate written notice to Landlord of any
         private or governmental investigation relating to Hazardous Substances
         on or about the Premises.

                  (2) At Tenant's own expense, Tenant shall promptly take all
         steps necessary to contain and remedy any release, spill, discharge or
         threatened discharge of Hazardous Substances on or at the Premises, the
         common areas or facilities in or relating to the Building, the Land,
         the Center, or the surrounding environment, and all resultant damage or
         injury to property, persons, and the environment. Landlord shall have
         the right, but not the obligation, to participate in and approve any
         environmental assessment or remedial cleanup plan for the Premises, the
         common areas or facilities in or relating to the Building, the Land and
         the Center. Tenant, its employees, agents and contractors shall fully
         cooperate with any and all federal, state and local governmental
         officials having jurisdiction over the Premises in resolving or
         addressing any situation involving the presence of Hazardous Substances
         on or about the Premises.

                  (3) Tenant shall be fully and completely liable to Landlord
         for any and all cleanup costs and any and all other charges, fees, and
         penalties (civil and criminal) imposed by any governmental authority
         with respect to Tenant's use, generation, handling, storage,
         containment, disposal, transportation, and/or sale of Hazardous
         Substances.

                  (4) Tenant shall indemnify, defend and save Landlord harmless
         from any and all of the costs, fees, penalties and charges assessed
         against or imposed upon Landlord (as well as Landlord's attorneys' fees
         and costs) as a result of Tenant's use, generation, handling, storage,
         containment, disposal, transportation, and/or sale of Hazardous
         Substances.

                  (5) Upon Tenant's default under Paragraph 16(d) herein or this
         Paragraph 16(e) and in addition to the rights and remedies set forth
         elsewhere in this Lease, Landlord shall be entitled to the following
         rights and remedies:

                           (A) At Landlord's option, to terminate this Lease
                  immediately; and

                           (B) To recover any and all damages associated with
                  the default,

including, but not limited to, cleanup costs and charges, civil and criminal
penalties and fees, loss of business and sales by Landlord and other tenants of
the Building or the Center, any and all damages and claims asserted by third
parties, and Landlord's attorneys' fees and costs.

The terms and provisions in this Paragraph 16(e) shall survive the expiration of
the Lease Term or the earlier termination of this Lease.

         17. Landlord's Right of Entry. Landlord and those persons authorized
by Landlord shall have the right to enter the Premises at all reasonable times
and upon reasonable notice for the purposes of making repairs, making
connections, installing utilities, providing services to the Premises or for any
other tenant, making inspections or showing the Premises to prospective
purchasers and/or lenders. Further, during the last six (6) months of the Lease
Term, including any extended Lease Term that has then been exercised by Tenant,
Landlord and those persons 


13
<PAGE>   14

authorized by it shall have the right, at reasonable times and upon reasonable
notice to Tenant, to show the Premises to prospective tenants. Notwithstanding
any term or provision in this Lease, including this Paragraph 17, to the
contrary, Landlord shall be entitled to enter the Premises at all times and
without any advance notice to Tenant if Landlord reasonably determines or
believes that an emergency circumstance or situation exists that requires such
entry.

         18. Eminent Domain. If any substantial portion of the Premises is taken
under the power of eminent domain (including any conveyance made in lieu
thereof) or if any such taking shall materially impair the normal operation of
Tenant's business, then either party shall have the right to terminate this
Lease by giving written notice of such termination within thirty (30) days after
such taking. If neither party elects to terminate this Lease pursuant to the
immediately preceding sentence, Landlord shall repair and restore the Premises
to a tenantable condition and the Annual Rental shall be equitably reduced as to
the portion of the Premises that is taken. All compensation awarded for any
taking (or the proceeds of a private sale in lieu thereof) shall be the property
of Landlord, whether such award is for compensation for damages to Landlord's or
Tenant's interest in the Premises, and Tenant hereby assigns all of its interest
in any such award to Landlord; provided, however, Landlord shall not have any
interest in any separate award made to Tenant for loss of business, moving
expenses or the taking of Tenant's trade fixtures or equipment if a separate
award for such items is made to Tenant.

         19. Events of Default and Landlord's Remedies.

         (a) Upon the occurrence of any one or more of the following events
(each, an "Event of Default"; collectively, "Events of Default"), Landlord shall
be entitled to exercise any rights or remedies available in this Lease, at law
or in equity. Events of Default shall be:

                  (1) Tenant's failure to pay when due any rental or other sum
         of money payable hereunder if not remedied within five (5) days after
         written notice thereof is given to Tenant (provided, however, and
         notwithstanding the foregoing to the contrary, Tenant shall not be
         entitled to such notice and cure period more than two (2) times during
         any given Lease Year).

                  (2) Failure by Tenant to perform any of the other terms,
         covenants or conditions contained in this Lease if such failure is not
         remedied within thirty (30) days after written notice thereof is given
         to Tenant.

                  (3) Tenant, or any guarantor of Tenant's obligations under
         this Lease (if any), becomes bankrupt or insolvent, files any debtor
         proceedings, files pursuant to any statute a petition in bankruptcy or
         insolvency or for reorganization, or files a petition for the
         appointment of a receiver or trustee for all or substantially all of
         such party's assets and such petition or appointment is not set aside
         within sixty (60) days from the date of such petition or appointment or
         if such party makes an assignment for the benefit of creditors or
         petitions for or enters into such an arrangement.

                  (4) Tenant vacates, abandons, or fails to operate in the
         Premises (or any substantial part thereof) or allows its leasehold
         estate under this Lease to be taken under any writ of execution and
         such writ is not vacated or set aside within thirty (30) days.

         (b) In addition to its other remedies at law or in equity, Landlord,
upon an Event of Default by Tenant, shall have the immediate right to reenter
and remove all persons and property from the Premises and dispose of such
property as it deems fit, all without resort to legal process and without being
guilty of trespassing or being liable for any damages caused thereby; provided,
however, Landlord may undertake the foregoing actions without resort to legal
process only if such actions can be completed in a manner that does not violate
applicable laws and legal requirements and without causing a disturbance of the
peace. If Landlord reenters the Premises, either with or without legal process
(subject to the limitations in the preceding sentence), it may either terminate
this Lease or, from time to time without terminating this Lease, make such
alterations and repairs as may be necessary or appropriate to relet the
Premises, and relet the Premises upon such terms and conditions as Landlord
deems advisable, without any responsibility of Landlord whatsoever to account to
Tenant for any surplus rents collected. Tenant also shall be liable for and
shall pay to Landlord, in addition to any other sum provided to 


14
<PAGE>   15

be paid herein, brokers' fees incurred by Landlord in connection with reletting
the whole or any part of the Premises; the costs of removing from the Premises
and storing Tenant's or other occupants' property; the costs of repairing,
altering, remodeling or otherwise putting the Premises into condition acceptable
to a new tenant or tenants, and all reasonable expenses incurred by Landlord in
enforcing or defending Landlord's rights and/or remedies under this Lease,
including reasonable attorneys' fees. No retaking of possession of the Premises
by Landlord shall be deemed as an election to terminate this Lease unless a
written notice of such intention is given by Landlord to Tenant at the time of
reentry; but, notwithstanding any such reentry or reletting without termination,
Landlord may at any time thereafter elect to terminate this Lease for such
previous default. In the event of an elected termination of this Lease by
Landlord, whether before or after reentry, Landlord may recover from Tenant
damages, including the costs of recovering the Premises, and Tenant shall remain
liable to Landlord for the total Annual Rental (which may, at Landlord's
election, be accelerated to be due and payable in full as of the Event of
Default or at any time thereafter and recoverable as damages in a lump sum) that
would have been payable by Tenant hereunder for the remainder of the Lease Term,
less the rentals actually received by Landlord from any reletting. (In the event
of any such acceleration, in determining the Annual Rental which would be
payable by Tenant subsequent to default, the Annual Rental rate for each
calendar year of the unexpired Lease Term shall be equal to the Annual Rental
rate payable by Tenant for the last calendar year prior to the default). If any
rent owing under this Lease is collected by or through an attorney, Tenant
agrees to pay Landlord's reasonable attorneys' fees to the extent allowed by
applicable law.

         20. Subordination. This Lease is subject and subordinate to any and all
mortgages or deeds of trust now or hereafter placed upon the property of which
the Premises are a part, and this clause shall be self-operative, without any
further instrument necessary to effect such subordination, provided any such
lender may, at its option and without seeking or obtaining Tenant's consent,
subordinate the lien of its mortgage or deed of trust to this Lease. At the
request from time to time of Landlord or any lender that holds a mortgage or
deed of trust on the property of which the Premises are a part, Tenant shall
promptly execute and deliver to Landlord any such instrument or instruments as
Landlord or such lender may reasonably request evidencing the subordination of
this Lease to such mortgage or deed of trust. Provided, however, as a condition
to Tenant's obligation to execute and deliver any such instrument(s), the
applicable lender must agree that Tenant's rights to quiet enjoyment and
possession of the Premises under this Lease shall not be divested by foreclosure
or other default proceedings under the applicable mortgage or deed of trust so
long as Tenant shall not be in default under this Lease. Tenant shall continue
its obligations under this Lease in full force and effect, notwithstanding any
foreclosure or default proceedings by any such lender.

         21. Assigning and Subletting. Tenant shall not assign, sublet,
mortgage, pledge or encumber this Lease, the Premises, or any interest in the
whole or in any portion thereof, without the prior written consent of Landlord
(which consent shall not be unreasonably withheld). If Tenant makes any such
assignment, mortgage, sublease or pledge (whether with or without Landlord's
written consent), Tenant named herein and any guarantor of Tenant's obligations
under this Lease shall nonetheless remain primarily liable for the performance
and observation of all of the terms of this Lease required to be observed or
performed by Tenant hereunder. Any rental or any fee or charge received by
Tenant in connection with any such assignment or sublease which is in excess of
the Annual Rental payable to Landlord hereunder shall be paid immediately by
Tenant to Landlord as additional rental under this Lease. In addition, Landlord
shall have the option, in its sole discretion, to terminate this Lease effective
as of the proposed effective date of any assignment or sublease, by giving
Tenant written notice thereof within thirty (30) days after Landlord's receipt
of said notice from Tenant; and in the event Tenant shall propose to sublet only
a portion of the Premises, Landlord shall have the additional option to
terminate this Lease as to that portion of the Premises proposed to be sublet.
Should Landlord not elect to so terminate this Lease in connection with any
proposed subletting or assignment, Landlord shall continue to have the right to
disapprove same (subject to the terms above). Upon any subletting or assignment
by Tenant in accordance with the terms hereof, any renewal options, expansion
options, and/or rights of first refusal granted herein shall become null and
void. Consent by Landlord to one or more assignments or sublettings shall not
operate as a waiver of Landlord's rights as to any subsequent assignments or
sublettings.


15
<PAGE>   16

         22. Covenant of Quiet Enjoyment. Landlord represents that it has full
right and authority to lease the Premises and that Tenant shall peacefully and
quietly hold and enjoy the Premises for the full Lease Term so long as Tenant
does not default in the performance of any of the terms hereof.

         23. Estoppel Certificates. Within ten (10) days after any request by
Landlord, Tenant shall deliver a written estoppel certificate addressed to
Landlord and/or any other party designated by Landlord, certifying any facts
that are then true with respect to this Lease, including, without limitation,
that this Lease is in full force and effect, that no default exists on the part
of Landlord or Tenant hereunder, that Tenant is in possession of the Premises,
that Tenant has commenced the payment of rent hereunder, and that there are no
defenses or offsets claimed by Tenant with respect to payment of rentals under
this Lease.

         24. Protection Against Liens. Tenant shall do all things necessary to
prevent the filing of any mechanic's, materialmen's or other types of liens
whatsoever, against all or any part of the Premises, the Building, the Land or
the Center by reason of any claims made by, against, through or under Tenant. If
any such lien is filed against the Premises, the Building, the Land or the
Center (or any portion thereof), Tenant shall either cause the same to be
discharged of record within twenty (20) days after filing or, if Tenant, in its
discretion and in good faith, determines that such lien should be contested,
Tenant shall furnish such security as may be necessary to prevent any
foreclosure proceedings against the Premises, the Building, the Land or the
Center (or any portion thereof) during the pendency of such contest. If Tenant
shall fail to discharge such lien within said time period or fail to furnish
such security, then Landlord may, at its election and in addition to any other
right or remedy available to it, discharge the lien by paying the amount claimed
to be due or by procuring the discharge by giving security or in such other
manner as may be allowed by law. If Landlord acts to discharge or secure any
such lien as permitted herein, then Tenant shall immediately reimburse Landlord
(as additional rent) for all sums paid and all costs and expenses (including
reasonable attorneys' fees) incurred by Landlord relative to such lien, together
with interest on the total expenses and costs at the maximum lawful rate.

         25. Force Majeure. Whenever a period of time is herein prescribed for
the taking of any action by Landlord, Landlord shall not be liable or
responsible for, and there shall be excluded from the computation of such period
of time, any delays due to any condition, matter or circumstance beyond the
reasonable control of Landlord (collectively, "Force Majeure Matters"; each, a
"Force Majeure Matter"), including, without limitation, the following: strikes;
defaults or failures to perform by contractors or subcontractors; lockouts; acts
of God; governmental restrictions, war or enemy action or invasion; civil
commotion; insurrection; riot; mob violence; malicious mischief or sabotage;
fire or any other casualty; adverse weather conditions or unusual inclement
weather; condemnation; unavailability of materials; failure of a governmental
instrumentality to act in a timely fashion; any litigation or other legal
proceeding which delays the approval of plans or the issuance of any grading or
building permit for construction, including, without limitation, the issuance of
an injunction enjoining such approval and/or issuance, as the case may be; any
law, order or regulation of any governmental, quasi-governmental, judicial or
military authority; or other similar cause. Without limiting the generality of
the foregoing, in the event a Force Majeure Matter affects Landlord's
construction and delivery obligation(s) relative to the Premises under this
Lease, the period of time during which Landlord may complete such construction
and delivery obligation(s) shall be extended by the same number of days as the
number of days of delay caused by such Force Majeure Matter on the critical path
of completing such construction and delivery obligation(s).

         26. Nonwaiver. No course of dealing between Landlord and Tenant and no
delay or omission of Landlord in exercising any right arising from Tenant's
default shall impair such right or be construed to be a waiver of a default.

         27. Landlord Liability. All obligations of Landlord hereunder will be
construed as covenants, not conditions, and all such obligations will be binding
upon Landlord only during the period of its ownership and possession of the
Building and not thereafter. The term "Landlord," under this Lease, shall mean
only the owner, for the time being, of the Building. If Landlord shall sell,
assign or transfer all or any part of its interest in the Premises or in this
Lease to a 


16
<PAGE>   17

successor in interest which expressly assumes the obligations of Landlord
hereunder, then the selling, assigning or transferring Landlord shall thereupon
be released and discharged from all covenants and obligations hereunder, and
Tenant shall look solely to such successor in interest for the performance of
all of Landlord's obligations hereunder. Tenant's obligations under this Lease
shall in no manner be affected by Landlord's assignment or transfer hereunder,
and Tenant shall thereafter attorn and look solely to such successor in interest
as the landlord hereunder. Notwithstanding any other provision hereof, Landlord
shall not have any personal liability hereunder. In the event of any breach or
default by Landlord in any term or provision of this Lease, Tenant agrees to
look solely to Landlord's interest in the Land and the Building; however, in no
event shall any deficiency judgment or any money judgment of any kind be sought
or obtained against Landlord.

         28. Holding Over. If Tenant remains in possession of the Premises or
any part thereof after the expiration of the Lease Term, whether with or without
Landlord's acquiescence, Tenant shall be deemed only a tenant at will and there
shall be no renewal of this Lease without a written agreement signed by both
parties specifying such renewal; in addition, the monthly Minimum Rental
required to be paid under this Lease relative to any holdover period shall
automatically become one hundred fifty percent (150%) of the monthly Minimum
Rental payable immediately prior to the expiration of the Lease Term. Tenant
also shall be liable for any and all damages, direct and consequential, suffered
by Landlord as a result of any holdover without Landlord's unequivocal written
acquiescence.

         29. Notices. Any notice allowed or required by this Lease shall be
deemed to have been sufficiently served if the same shall be in writing and
placed in the United States Mail, via certified mail or registered mail, return

         The addresses of Landlord and Tenant to which notices shall be directed

         30. Miscellaneous.

         (a) Rules and Regulations. Attached hereto as Exhibit D are the rules
and regulations currently in effect with respect to the Building. Landlord shall
have the right from time to time to reasonably amend these rules and regulations
for Tenant's use of the Premises, the Building and the Land. Tenant shall abide
by and actively enforce such rules and regulations, including, without
limitation, rules and regulations governing parking of vehicles on designated
portions of the Land as to its employees, agents, invitees and licensees.

         (b) Evidence of Authority. If requested by Landlord, Tenant shall
furnish appropriate legal documentation evidencing the valid existence and good
standing of Tenant and the authority of any parties signing this Lease on behalf
of Tenant to act for Tenant.

         (c) Nature and Extent of Agreement. This Lease, together with all
exhibits hereto, contains the complete agreement of the parties concerning the
subject matter hereof, and there are no oral or written understandings,
representations, or agreements pertaining thereto which have not been
incorporated herein. This Lease creates only the relationship of landlord and
tenant between the parties, and nothing herein shall impose upon either party
any powers, obligations or restrictions not expressed herein. This Lease shall
be construed and governed by the laws of the state in which the Premises are
located.

         (d) Severability. If any term or provision of this Lease, or the
application thereof to 


17
<PAGE>   18

any person or circumstance shall, to any extent, be invalid or unenforceable,
the remainder of this Lease, or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby, and each term and provision of
this Lease shall be valid and enforced to the fullest extent permitted by law,
notwithstanding the invalidity of any other term or provision hereof.

         (e) Binding Effect. This Lease shall be binding upon and shall inure to
the benefit of the parties hereto and their respective heirs, successors and
assigns. This Lease shall not be binding on Landlord until executed by an
officer of Landlord having a title of Vice President or higher and delivered to
Tenant. No amendment or modification of this Lease shall be binding upon
Landlord unless same is in writing and executed by an officer of Landlord having
a title of Vice President or higher.

         (f) Captions and Headings. The captions and headings in this Lease are
for convenience and reference only, and they shall in no way be held to explain,
modify, or construe the meaning of the terms of this Lease.

         (g) Security Deposit. Tenant shall pay to Landlord on the Lease
Execution Date a sum (the "Security Deposit") equal to one month's Minimum
Rental as security for the performance of all obligations to be performed by
Tenant hereunder. The Security Deposit may be held by Landlord in such manner as
it shall elect, and Landlord shall be entitled to retain any interest which
accrues on the Security Deposit. In the event of a default by Tenant hereunder,
Landlord may, at its option, apply all or any part of the Security Deposit to
cure the default, and thereupon Tenant shall immediately redeposit with Landlord
the amount so applied in order that Landlord will always have the full Security
Deposit on hand during the Lease Term. Upon the termination of this Lease and
provided that Tenant is not in default hereunder, Landlord shall refund to
Tenant any of the remaining balance of the Security Deposit, subject to final
adjustments for payment of any rental required to be paid by Tenant under this
Lease and compliance by Tenant with all of its obligations hereunder. If the
Premises are sold, Landlord shall transfer the Security Deposit to the new
owner; and upon such transfer, Landlord shall thereupon be released from all
liability for the Security Deposit, and Tenant thereafter shall look solely to
the new owner for the Security Deposit. The terms of the immediately preceding
sentence shall apply to every transfer of the Security Deposit.

         (h) Lease Review. The submission of this Lease to Tenant for review
does not constitute a reservation for or option for the Premises, and this Lease
shall become effective as a contract only upon execution and delivery by
Landlord and Tenant.

         (i) Brokerage. Landlord warrants and represents to Tenant that Landlord
has not engaged or contracted with any person, firm or entity to serve or act as
a Realtor(R), broker, agent or finder, other than Broker (if any) identified in
the Basic Lease Information, for the purpose of leasing the Premises or in
regard to this Lease. Tenant warrants and represents to Landlord that Tenant has
not engaged, contracted with or dealt with any person, firm or entity (other
than Broker, if any) to serve or act as a Realtor(R), broker, agent or finder
for the purpose of leasing the Premises or in regard to this Lease. Landlord
agrees to be solely responsible for the payment of any commission to Broker (if
any) relating to this Lease pursuant to a separate agreement between Landlord
and Broker (if any). Tenant shall and does hereby indemnify and hold harmless
Landlord from and against any claim for any consulting fee, finder's fee,
commission, or like compensation, including reasonable attorneys' fees in
defense thereof, payable in connection with this Lease and asserted by any party
arising out of any act or agreement by Tenant, excluding the commission payable
by Landlord to Broker (if any) as described above. Landlord shall and does
hereby indemnify and hold harmless Tenant from and against any claim for any
consulting fee, finder's fee, commission, or like compensation, including
reasonable attorneys' fees in defense thereof, payable in connection with this
Lease and asserted by any party arising out of any act or agreement by Landlord
(including the commission payable by Landlord to Broker, if any, as described
above).

         (j) Memorandum of Lease. Upon the request of either party, the other
party shall join in the execution of a memorandum of this Lease (a "Memorandum")
in recordable form. Either party may record the Memorandum in the appropriate
land record office, at its own expense. However, neither party shall record this
Lease (or any portion thereof) without the written consent of the other party.

         (k) Advance Rental Payment.  [Intentionally deleted.]

         (l) Landlord's Consent. Whenever this Lease requires Landlord's consent
to or approval of any item or matter, Landlord may condition such consent or
approval on payment or reimbursement by Tenant of all costs and expenses
incurred by Landlord in connection with reviewing and responding to such item or
matter.

         (m) Survival of Obligations. Notwithstanding any term or provision in
this Lease to the contrary, any liability or obligation of Landlord or Tenant
arising during or accruing with respect to the Lease Term shall survive the
expiration or earlier termination of this Lease, including, without limitation,
obligations and liabilities relating to (i) rental payments, (ii) the condition
of the Premises and the removal of Tenant's property, and (iii) indemnity and
hold harmless provisions in this Lease.

         (n) Confidentiality. Tenant shall not disclose the terms of this Lease
to any third party except (i) legal counsel to Tenant, (ii) any assignee of
Tenant's interest in this Lease or any sublessee of Tenant relative to the
Premises (or any portion thereof), (iii) as required by applicable law or by
subpoena or other similar legal process, or (iv) for financial reporting
purposes.

         (o) Attorneys' Fees. In the event either party defaults in the
performance of any of the terms of this Lease and the other party employs
attorney(s) in connection therewith, the defaulting party agrees to pay the
prevailing party's reasonable attorneys' fees (calculated at such attorneys'
reasonable and customary hourly rates and without regard to the amount in
controversy) and costs of litigation.

         (p) Time of Performance. Except as expressly otherwise herein provided,
with respect to all required acts of Tenant, time is of the essence of this
Lease.

         (q) Real Estate Investment Trust. During the Lease Term, should a real
estate investment trust become Landlord hereunder, all provisions of this Lease
shall remain in full force and effect except as modified by this Paragraph
30(g). If Landlord in good faith determines that its status as a real estate
investment trust under the provisions of the Internal Revenue Code of 1986, as
heretofore or hereafter amended, will be jeopardized because of any provision of
this Lease, Landlord may request reasonable amendments to this Lease and Tenant
will not unreasonably withhold, delay or defer its consent thereto, provided
that such amendments do not (a) increase the monetary obligations of Tenant
pursuant to this Lease or (b) in any other manner adversely affect Tenant's
interest in the Premises.

         (r) Additional Terms and Provisions. The additional terms and
provisions, if any, set forth on Exhibit E attached to this Lease are
incorporated herein by reference. If there is no Exhibit E attached to this
Lease, there are no such additional terms and provisions. If there is an Exhibit
E attached to this Lease, the additional terms and provisions set forth thereon
shall control if in conflict with any of the terms and provisions of this Lease.

         IN WITNESS WHEREOF, the parties have caused this Lease to be duly
executed under seal as of the Lease Execution Date pursuant to authority duly
given.

     north/south taxiway to the west of the NORTHWEST HANGAR as shown on 
     Exhibit "A".

2.   MASTER LEASE:

     SUBLESSEE hereby acknowledges that the Premises and SUBLESSOR'S rights 
     thereto are subject to the Master Lease with Broward County, a copy of 
     which is on file in the offices of Broward County Aviation Department, 
     Division of Airports and SUBLESSOR'S offices, and SUBLESSEE hereby 
     represents that it is familiar with the provisions of same and said Master 
     Lease is incorporated herein by reference. SUBLESSEE acknowledges that (a) 
     it will comply with each and every provision of the Master Lease in 
     accordance with the terms hereof as such provisions relate to the 
     Premises, except as such provisions are supplemented or amended by this 
     Sublease Agreement; (b) any and all rights and reservations of Broward 
     County under the Master Lease as such rights or reservations may apply to 
     the leased Land described in the Master Lease or SUBLESSOR shall likewise 
     apply to the Premises and SUBLESSEE under this Sublease Agreement; and (c) 
     any remedy which Broward County may have against SUBLESSOR or the leased 
     premises under the Master Lease shall become a remedy of SUBLESSOR and 
     Broward County against SUBLESSEE and the Premises under this Sublease 
     Agreement. The foregoing shall in no manner limit SUBLESSOR's right to 
     require SUBLESSEE to comply with SUBLESSEE's obligations under this 
     Sublease Agreement or SUBLESSEE's obligations, as limited by this 
     Agreement, under the Master Lease.

3.   LEASE TERM:

     The term of this Lease is for FOUR (4) years commencing December 15, 1997 
     and continuing through December 14, 2001, subject to and conditioned upon 
     the approval of Broward County Florida, and the fulfillment of all terms 
     and conditions of this lease. Furthermore, the SUBLESSOR does hereby grant 
     SUBLESSEE an additional TWO YEAR NINE AND ONE HALF MONTHS Option to Lease

     the end of the initial lease term (December 14, 2001).

     RENTAL AMOUNT:

     The agreed total base annual rental amount for year one shall be $96,000 or
     $8,000 per month plus any applicable sales or use tax or other sums imposed
     by law on such payments. It is recognized that, for purposes of any rental
     increases imposed on SUBLESSOR by Broward County, SUBLESSEE shall occupy
     50% of the total premises leased by SUBLESSOR and will be responsible to
     pay, as additional rent, 50% of any such Broward County imposed rental
     increase. Therefore, 50% of the final rent increase resulting from the
     revaluation of the premises in August 1997, which is currently being
     negotiated with Broward County (estimated to be between $500 and $2,200 per
     month), will be added to the base monthly rent of $8,000 retroactive to
     December 15, 1997. It is further agreed that 50% of any rent increase
     resulting from the re-evaluation of the premises by Broward County as of
     August 2002 will be added to the then monthly rental rate paid by SUBLESSEE
     during the option period if said option has been exercised by SUBLESSEE. In
     addition, at the time of percentage Consumer Price Index (CPI) increases
     (if any) imposed by Broward County on SUBLESSOR, SUBLESSEE'S annual rental
     amount will be increased by a dollar amount equal to 50% of that CPI
     percentage increase. Base monthly rent will also increase beginning the
     second year (December 15, 1998) as well as at the beginning of each year
     thereafter including each option year by an amount of $500 per month. All
     rents are due monthly in advance on the first calendar day of each month
     payable to: CRESCENT HELICOPTERS, 7750 Pines Blvd., Pembroke Pines, FL
     33024. The first lease payment due December 15, 1997 will be for both the
     first and last month's base lease payments amounting to $16,000. A 10%
     penalty fee will be incurred by the SUBLESSEE for any payments not received
     by the SUBLESSOR by the seventh calendar day of the applicable month.

5.   DEPOSIT:

     Receipt is hereby made in the amount of $8,500 from SUBLESSEE. Upon
     acceptance of this lease, such deposit shall belong to the SUBLESSOR and
     applied as a Security Deposit for the period of said Lease. Said Security
     Deposit shall secure the performance of the SUBLESSEE'S obligation
     hereunder and shall constitute a fund from which any liens incurred by
     SUBLESSEE or damages caused by SUBLESSEE and suffered by SUBLESSOR shall be
     paid. Any Deposit remaining upon termination shall be returned to the
     SUBLESSEE. SUBLESSEE shall not have the right to apply the Security Deposit
     in payment of monthly rent.

6.   LESSEE'S OBLIGATIONS:

          improvements shall at the end of the lease term become the property of
          the SUBLESSOR unless said improvements are removed by SUBLESSEE and

          AND ACCEPTED. Any material failure on the part of the SUBLESSEE herein
          to comply with the terms, conditions, rules or regulations now in
          existence, or which may be hereinafter required by Broward County,
          Florida, to whom this Lease is subservient, or the failure to pay rent
          within Seven calendar days after the same is due and payable, shall,
          at the option of the SUBLESSOR, work a forfeiture of this said
          contract and of all rights of the SUBLESSEE hereunder, and, thereupon,
          the SUBLESSOR, it's agent or attorneys, shall have the right to enter
          said premises and remove therefrom all persons and/or personal
          property located therein, forcibly or otherwise.

          the end of the term of this Lease, or any extension thereof, or if
          said SUBLESSEE shall suffer the rent or any other sums of money due

          sums of money due SUBLESSOR herein provided shall not be realized by

          releting, the said SUBLESSEE shall pay any deficiency.

16.  LIMITATION OF LANDLORD'S LIABILITY:

     SUBLESSOR shall not be liable for any damages or injury by any cause, which

17.  DEFAULT AND REMEDIES:

     A.  DEFAULT. The occurrence of any of the following shall constitute a
         material default and breach of this Lease by SUBLESSEE:
          (1) Any failure by SUBLESSEE to pay Minimum Rent or Percentage Rent or
              any other monetary sums required to be paid hereunder, where such
              failure continues for three (3) days after written notice by
              SUBLESSOR to SUBLESSEE:
          (2) The failure to occupy or the abandonment or vacation of the
              Premises by SUBLESSEE;
          (3) The repudiation of this Lease by SUBLESSEE, any action by
              SUBLESSEE which renders performances by SUBLESSEE of its
              obligations under this Lease impossible, or any action by
              SUBLESSEE which demonstrates an intent by SUBLESSEE not to perform
              an obligation under this Lease or not to continue with the
              performance of obligations under this Lease;
          (4) A failure by SUBLESSEE to observe and perform any other provisions
              of this Lease to be observed or performed by SUBLESSEE, where such
              failure continues for fifteen (15) days after written notice
              thereof by SUBLESSOR to SUBLESSEE; provided, however, that if the
              nature of the default is such that the same cannot reasonably be
              cured within said fifteen (15) day period, SUBLESSEE shall not be
              deemed to be in default if SUBLESSEE shall within such period
              commence such cure and thereafter diligently prosecute the same to
              completion;
          (5) The making by SUBLESSEE of any general assignment or general
              arrangement for the benefit of creditors, the filing by or against
              SUBLESSEE of a petition to have SUBLESSEE adjudged  bankrupt or of
              a petition for reorganization or arrangement under any law
              relating to bankruptcy (unless, in the case of a petition filed
              against SUBLESSEE, the same is dismissed within sixty (60) days),
              the appointment of a trustee or receiver to take possession of
              substantially all of SUBLESSEE'S assets or of SUBLESSEE'S interest
              in this Lease, where possession is not restored to SUBLESSEE
              within thirty (30) days, or the attachment, execution or other
              judicial seizure of substantially all of SUBLESSEE'S assets
              located at the Premises or of SUBLESSEE'S interest in this Lease,
              where such seizure is not discharged within thirty (30) days.
     B.  NOTICE. SUBLESSEE shall pay SUBLESSOR the sum of One Hundred and
         No/100ths dollars ($100.00) in addition to any other obligations
         hereunder for the cost of sending each Notice to Default. 
     C.  REMEDIES. In the event of any such material default or breach by
         SUBLESSEE, SUBLESSOR may at any time thereafter, without limiting
         SUBLESSOR in the exercise of any right of remedy at law or in equity
         which SUBLESSOR may have by reason of such default or breach:
         (1)  Maintain this Lease in full force and effect and recover the Rent
              and other monetary charges as they become due (or alternatively,
              if SUBLESSOR exercises the right to accelerate the Rent due
              hereunder as set forth in Section 17D below, recover all Rent and
              other monetary charges due as a result of acceleration), without
              terminating SUBLESSEE'S right to possession irrespective of
              whether SUBLESSEE shall have


                                       5
<PAGE>   10
               abandoned the Premises. In the event SUBLESSOR elects not to
               terminate this Lease, SUBLESSOR shall nevertheless have the right
               to attempt to re-let the Premises at such rent and upon such
               conditions and for such a term, and to do all acts necessary to
               maintain or preserve the Premises as SUBLESSOR deems reasonable
               and necessary without being deemed to have elected to terminate
               this Lease, including removal of all persons and property from
               the Premises; such property may be removed and stored in a public
               warehouse or elsewhere at the cost of and for the account of
               SUBLESSEE, and if SUBLESSEE does not pay for storage, then sold
               at public auction; the proceeds of such sale shall first be
               applied to payment of the expenses of such sale, second to
               amounts due SUBLESSOR and the balance, if any, to SUBLESSEE. In
               the event any re-letting occurs, SUBLESSEE'S right to possession
               of the Premises under this Lease shall terminate automatically
               upon the new SUBLESSEE taking possession of the Premises, but
               SUBLESSEE shall nevertheless be responsible for damages, more
               particularly described in Sections 17C.(2)a through 17C.(2)e.
               Notwithstanding that SUBLESSOR fails to elect to terminate the
               Lease initially, SUBLESSOR may at any time during the term of
               this Lease elect to terminate this Lease by virtue of such
               previous default of SUBLESSEE.
          (2)  Terminate SUBLESSEE'S right to possession by any lawful means
               and SUBLESSEE shall immediately surrender possession of the
               Premises to SUBLESSOR. In such event SUBLESSOR shall be entitled
               to recover from SUBLESSEE all damages incurred by SUBLESSOR by
               reason of SUBLESSEE'S default, including without limitation
               thereto the following:
                   a.) the worth at the time of award of any unpaid Rent which
                       had been earned at the time of such termination; plus
                   b.) the worth at the time of award of the amount by which the
                       unpaid Rent which would have been earned after
                       termination until the time of award exceeds, the amount
                       of such rental loss that could have been reasonably
                       avoided; plus
                   c.) the amount by which the unpaid Rent for the balance of
                       the term after the time of award exceeds the amount of
                       such rental loss that could be reasonably avoided; plus
                   d.) any other amount necessary to compensate SUBLESSOR for
                       all the detriment proximately caused by SUBLESSEES
                       failure to perform its obligation under this Lease or
                       which in the ordinary course of events would be likely to
                       result therefrom including costs and expenses incurred by
                       SUBLESSOR in making the Premises ready for a new
                       SUBLESSEE; plus
                   e.) at SUBLESSOR'S election, such other amounts in addition
                       to or in lieu of the foregoing as may be permitted from
                       time to time by applicable law of the State where the
                       Premises are located. Upon any such re-entry, SUBLESSOR
                       shall have the right to make any reasonable repairs,
                       alterations or modifications to the Premises, which
                       SUBLESSOR in its sole discretion deems reasonable and
                       necessary. As used in Section 17C.(2)a. above, the "worth
                       at the time of award" is computed by allowing interest at
                       the rate of one percent (1%) per month from the date of
                       default. The term Rent, means the rent to be paid
                       pursuant to Paragraph 4 and all other monetary sums
                       required to be paid by SUBLESSEE pursuant to the terms of
                       this Lease.
     D.  ACCELERATION OF RENT. In the event of any such material default or
         breach by SUBLESSEE, SUBLESSOR may, at its election and without
         limiting SUBLESSOR'S other rights and remedies, accelerate the payment
         of all Rent and other monetary sums payable by 


                                       6
<PAGE>   11
             SUBLESSEE for the balance of the term and upon any such elections 
             such sums shall be immediately due and payable in full.
     E.      SPECIAL DAMAGES. In addition to the damages for breach of this 
             Lease described in Paragraph 17C. and 17D. SUBLESSEE agrees that 
             SUBLESSOR shall be entitled to receive from SUBLESSEE any and all
             costs in connection with SUBLESSEE'S default hereunder, including
             without limitation, administrative costs of SUBLESSOR associated 
             with SUBLESSEE'S default, costs of repairing and/or remodeling the
             Premises for new SUBLESSEES and leasing commissions for any leasing
             agent engaged to re-let the Premises. 
     F.      LATE CHARGES. SUBLESSEE hereby acknowledges that late payment by
             SUBLESSEE to SUBLESSOR of Rent and other sums due hereunder will 
             cause SUBLESSOR to incur costs not contemplated by this Lease, the
             exact amount of which are unknown and will be extremely difficult
             to ascertain other than such late charges which may be imposed on
             SUBLESSOR by the terms of any mortgage or trust deed covering the
             Premises. Accordingly, if any installment of Rent or any other sums
             due from SUBLESSEE shall not be received by SUBLESSOR or 
             SUBLESSOR'S designee within seven (7) days after such amount shall
             be due, SUBLESSEE shall pay to SUBLESSOR in addition to any late 
             charges incurred by SUBLESSOR under any mortgage or deed of trust
             covering the Premises, a late charge equal to ten percent (10%) of
             the amount(s) past due and additionally all such installments of 
             Rent or other sums due shall bear interest from the seventh day 
             forward at the rate of One percent (1%) per month until paid in 
             full. The parties hereby agree that such late charges represents 
             fair and reasonable estimate of the costs SUBLESSOR will incur by
             reason of late payment by SUBLESSEE. Acceptance of such late charge
             by SUBLESSOR shall in no event constitute a waiver of SUBLESSEE'S 
             default with respect to such overdue amount, nor prevent SUBLESSOR
             from exercising any of the rights and remedies granted hereunder. 
     G.      DEFAULT BY SUBLESSOR. SUBLESSOR shall not be in default unless 
             SUBLESSOR fails to perform obligations required of SUBLESSOR within
             a reasonable time, but in no event later that thirty (30) days 
             after written notice by SUBLESSEE to SUBLESSOR and to the holder of
             any mortgage or deed of trust covering the Premises furnished to 
             SUBLESSEE in writing, specifying wherein SUBLESSOR has failed to 
             perform such obligations; provided, however, that if the nature of
             SUBLESSOR'S obligation is such that more than thirty (30) days are
             required for performance, then SUBLESSOR shall not be in default if
             SUBLESSOR commences performance within such thirty (30) day period
             and thereafter diligently prosecutes the same to completion; 
             provided, further, that in the event that SUBLESSOR has defaulted 
             in the payments of a monetary obligation and SUBLESSEE has advanced
             monies to pay such obligation. SUBLESSOR shall pay SUBLESSEE 
             interest on such monies advanced at a rate of one percent (1%) per
             month until paid in full. 
     H.      BANKRUPTCY. 
             (1.)      CHAPTER 7. In the event that SUBLESSEE shall become a 
                       debtor in a case filed under Chapter 7 of the Bankruptcy
                       Code, and SUBLESSEE'S trustee or SUBLESSEE shall elect to
                       assume this Lease for the purpose of assigning the same
                       or otherwise, such election and assignment may be made 
                       only if the provisions of Sections 17H.(2), 17H.(3), and
                       17H.(5) are satisfied. If SUBLESSEE or SUBLESSEE'S 
                       trustee shall fail to elect to assume this Lease within
                       sixty (60) days after the filing of such petition or such
                       additional time as provided by the court within such 60-
                       day period, this Lease shall be deemed to have been 
                       rejected. Immediately thereupon SUBLESSOR shall be 
                       entitled to possession of the Premises without further 
                       obligation to SUBLESSEE or SUBLESSEE'S trustee and this
                       Lease, upon the election of SUBLESSOR, shall terminate 
                       but SUBLESSOR'S right to be compensated for



                                       7

<PAGE>   12
               damages (including, without limitation, damages pursuant to this 
               Paragraph 17) in any such proceeding shall survive whether or 
               not the Lease is terminated.
          (2.) CHAPTER 11. In the event that SUBLESSEE shall become a debtor in 
               a case filed under Chapter 11 of the Bankruptcy Code, or in a 
               case filed under Chapter 7 of the Bankruptcy Code which is 
               converted to Chapter 11, SUBLESSEE'S trustee or SUBLESSEE, as 
               debtor-in-possession, must elect to assume this Lease within 
               sixty (60) days from the date of the filing of the petition 
               under Chapter 11 or conversion thereto, or SUBLESSEE'S trustee 
               or the debtor-in-possession shall be deemed to have rejected 
               this Lease. Immediately thereupon SUBLESSOR shall be entitled to 
               possession of the Premises without further obligation to 
               SUBLESSEE or SUBLESSEE'S trustee and this Lease, upon the 
               election of SUBLESSOR, shall terminate, but SUBLESSOR'S right to 
               be compensated for damages (including, without limitation, 
               damages pursuant to this Paragraph 17) in any such proceeding 
               shall survive whether or not the Lease is terminated.
                    Should SUBLESSEE'S trustee, or SUBLESSEE or debtor-in-
               possession elect to assume this lease, it can do so only if:
               a.)  SUBLESSEE'S trustee or the debtor-in-possession has cured 
                    all defaults under this Lease, or has provided SUBLESSOR 
                    with Assurance (as defined below) that it will cure all 
                    defaults susceptible of being cured by the payment of money 
                    on the date of such assumption, and that it will cure all 
                    other defaults under this Lease which are susceptible of 
                    being cured by the performance of any act within fifteen 
                    (15) days from the date of such assumption.
               b.)  SUBLESSEE'S trustee or the debtor-in-possession has
                    compensated or has provided SUBLESSOR with Assurance that 
                    within ten (10) days from the date of such assumption that 
                    it will compensate SUBLESSEE for any actual pecuniary loss 
                    incurred by SUBLESSEE arising from the default of 
                    SUBLESSEE, SUBLESSEE'S trustee, or the debtor-in-possession 
                    indicated in any statement of actual pecuniary loss sent 
                    by SUBLESSOR to SUBLESSEE'S trustee or the 
                    debtor-in-possession.
               c.)  SUBLESSEE'S trustee or the debtor-in-possession has 
                    provided SUBLESSOR with Assurance of future performance of 
                    each of the obligations under this Lease of SUBLESSEE, 
                    SUBLESSEE'S trustee or the debtor-in-possession, and if 
                    SUBLESSEE'S trustee or the debtor-in-possession has 
                    provided such assurance, SUBLESSEE'S trustee or the 
                    debtor-in-possession shall also deposit with, or provide 
                    Assurance as defined below to SUBLESSOR, as security for 
                    the timely payment of Rent hereunder, an amount equal to 
                    six (6) monthly installment payments of the Rent, provided 
                    all terms and provisions of this Lease shall have been 
                    complied with. The obligations imposed upon SUBLESSEE'S 
                    trustee or the debtor-in-possession by this paragraph shall 
                    continue with respect to SUBLESSEE or any assignee of this 
                    Lease after the completion of bankruptcy proceedings.
               d.)  Such assumption will not breach or cause a default under 
                    any provision of any other lease, mortgage, financing 
                    agreement or other agreement by which SUBLESSOR is bound 
                    relating to the Premises. For purposes of this Paragraph 
                    17H, SUBLESSOR and SUBLESSEE acknowledge that "Assurance" 
                    shall mean no less than: SUBLESSEE'S trustee or the 
                    debtor-in-possession has and will continue to have 
                    sufficient unencumbered assets after the payment of all 
                    secured obligations and administrative expenses to assure 
                    SUBLESSOR that sufficient funds will be available to 
                    fulfill the obligations of SUBLESSEE under this Lease and 
                    there shall have been deposited with SUBLESSOR, or the 
                    Bankruptcy Court


                                       8
<PAGE>   13
                      shall have entered an order segregating sufficient cash
                      payable to SUBLESSOR and/or SUBLESSEE'S trustee or
                      debtor-in-possession shall have been granted a valid and
                      perfected first lien and security interest and/or mortgage
                      in property of SUBLESSEE, SUBLESSEE'S trustee of the
                      debtor-in-possession, acceptable as to value and kind to
                      SUBLESSOR, to secure to SUBLESSOR the obligation of
                      SUBLESSEE'S trustee or the debtor-in-possession to cure
                      the defaults under this Lease, monetary and/or
                      non-monetary, within the time periods set forth above.
          (3). SUBSEQUENT PETITIONS. In the event that this Lease is assumed in 
               accordance with Paragraph 17H(2) and thereafter SUBLESSEE is
               liquidated or files or has filed against it a subsequent petition
               under Chapter 7 or Chapter 11 or the Bankruptcy Code, SUBLESSOR
               may, at it's option, terminate this Lease and all rights of
               SUBLESSEE hereunder by giving SUBLESSEE notice of its election to
               so terminate within thirty (30) days after the occurrence of
               either of such events.
          (4). ADEQUATE ASSURANCES. If SUBLESSEE'S trustee or the 
               debtor-in-possession has assumed the Lease pursuant to the terms
               and provisions of Sections 17H(1), 17H(2) and 17H(3) for the
               purposes of assigning (or thereafter elects to assign) this
               Lease, this Lease may be so assigned only if the proposed
               assignee has provided adequate assurance of future performances
               of all of the terms, covenants and conditions of this Lease to be
               performed by SUBLESSEE. SUBLESSOR shall be entitled to receive
               all cash proceeds of such assignment. As used herein, "adequate
               assurance of future performance" shall mean and include all such
               requirements as set forth in Section 365 of Title II, U.S. Code
               (as may be amended) are met, and further that no less than each
               of the following conditions has been satisfied.
               a). The proposed assignee has furnished SUBLESSOR with either 
                   (i) a current financial statement audited by a certified
                   public accountant indicating a net worth and working capital
                   in amounts which SUBLESSOR reasonably determines to be
                   sufficient to assure the future performance by such assignee
                   of SUBLESSEE'S obligations under this Lease, or (ii) a
                   guarantee or guarantees, in form and substance satisfactory
                   to SUBLESSOR, from one or more persons with a net worth which
                   SUBLESSOR reasonable determines to be sufficient to secure
                   the SUBLESSEE'S obligations hereunder, and has also furnished
                   information with respect to the proposed assignee's
                   management ability, expertise and experience in SUBLESSEE'S
                   business and SUBLESSOR has reasonably determined that the
                   proposed assignee has the management expertise and experience
                   to operate the business conducted on the Premises.
               b). SUBLESSOR has obtained all consents or waivers from others 
                   required under any lease, mortgage, financing arrangement or
                   other agreement by which SUBLESSOR is bound, in order to
                   permit SUBLESSOR to consent to such assignment without
                   violating the terms of any such agreement.
               c). The proposed assignment will not release or impair any 
                   guaranty of the obligations of SUBLESSEE (including the
                   proposed assignee) under this Lease.
          (5). USE AND OCCUPANCY CHARGES. When, pursuant to the Bankruptcy 
               Code, SUBLESSEE'S trustee or the debtor-in-possession shall be
               obligated to pay reasonable use and occupancy charges for the use
               of the Premises, such charges shall not be less than the Base
               Rent plus Broward County valuation rental increase, CPI
               increases, and other charges due hereunder. No acceptance by
               SUBLESSOR of said use and occupancy charges, or of Rent hereunder
               shall constitute a waiver of any of the provisions of this
               Paragraph 17H, or any of SUBLESSOR'S rights thereunder.

          (6)  NO TRANSFER IN BANKRUPTCY WITHOUT CONSENT. Neither the whole nor 
               any portion of SUBLESSEE'S interest in this Lease or its estate 
               in the Premises shall pass to any trustee, receiver, or assignee 
               for the benefit of creditors, or any other person or entity, or 
               otherwise by operation of law under the laws of any state having 
               jurisdiction of the person or property of SUBLESSEE unless the 
               requirements and conditions of this Paragraph 17H, are truly met 
               or unless SUBLESSOR shall have otherwise consented to such 
               transfer in writing. No acceptance by SUBLESSOR of installment 
               payments or Rent or any other payments from any such trustee, 
               receiver, assignee, person or other entity shall be deemed to 
               constitute such consent by SUBLESSOR nor shall it be deemed a 
               waiver of SUBLESSOR'S rights under this Paragraph 17H including 
               the right to terminate this Lease for any transfer of 
               SUBLESSEE'S interest under this Lease without such consent.

time to time official receipts evidencing payment of taxes as required in

hereto if the commencement and the end of the term of this lease do not coincide
with the beginning or end of the tax year.

         Section 3.03 - Installment Payment. Lessee shall have the right to
execute in the name of the Lessor and as its attorney in fact such agreement or
agreements or other instrument which may be required or permitted by law to
permit the payment of such taxes or assessments in installments, but Lessee
shall not be liable to pay any installments for taxes not due at the end of this
original or any renewed term after occupancy of the Lessee has closed.

         Section 3.04 - Unpaid Taxes. If Lessee fails to pay any such taxes,
assessments or other public charges which it is obligated to pay as provided in
this Article, before the same become delinquent, then and in such event, Lessor
may pay the same, together with any interest and penalties thereon, and the
amount so paid shall be deemed rent immediately due and payable by Lessee to
Lessor on demand, together with interest thereon at the rate of ten percent
(10%) per annum plus an additional service fee of two percent (2%).

         Section 3.05 - Contest of Taxes. Anything in this Article to the
contrary notwithstanding, Lessor agrees that Lessee shall have the right, at
Lessee's sole cost and expense, to contest the legality, validity, or the basis
of calculation, of any of the taxes, assessments or other public charges
provided to be paid by Lessee, but no such contest shall be carried on or
maintained by Lessee after such taxes, assessments or other public charges
become delinquent unless Lessee shall have duly paid the amount involved under
protest or shall procure and maintain a stay of all proceedings to enforce any
collection thereof and any forfeiture or sale of the Demised Premises, and shall
also provide for payment thereof together with all penalties, interest, cost and
expense by deposit of a sufficient sum of money or by a good and sufficient
undertaking as may be required by law to accomplish such stay. Lessor agrees
that it will, at the request of Lessee, execute or join in the execution of any
instrument or documents necessary in connection with any such contest except
bonds or undertakings. In the event any such contest is made by Lessee, Lessee
shall promptly, upon final determination thereof adversely to Lessee, pay and
discharge the amount involved, or affected by, any such contest, together with
any penalties, fines, interest, costs and expenses that may have accrued
thereon.

         Section 3.06 - Maintenance and Repairs. As between the Lessor and the

maintenance costs and shall take good care of the Demised Premises and keep the
same and all parts thereof, together with any and all alterations, additions and
improvements therein or thereto, in good order and condition, except for normal
wear and tear, damage done by casualty not covered by the provisions of the
usual fire and extended coverage insurance, or acts of the Lessor.

         The Lessor agrees to maintain the premises and structure in a good

not be altered or changed without the written consent of the Lessor and the
Lessee shall not attach anything whatsoever to the Demised Premises that might
damage the Demised Premises or that might be a permanent attachment to the
Demised Premises without the written consent of Lessor. The consent of Lessor
shall not be unreasonably withheld. The costs of any such alterations or
improvements approved by Lessor shall be borne by the Lessee and shall remain
upon and be surrendered with the Demised Premises; provided, however, that any
trade fixtures installed by Lessee may be removed by Lessee at the expiration of
the term of this Lease, or of any renewal, provided that the Lessee is not in
default under the terms hereof and provided further that any damage occasioned
by any such removal shall be paid by Lessee.

         Section 3.08 - Fees and Commissions. Lessor and Lessee represent to
each other that neither party has engaged the services of a real estate broker
or agent in negotiating or consuming the closing of this Lease. Lessor and
Lessee agree to indemnify and hold each other free and harmless of any
obligation for real estate commissions, finder's fees and legal fees earned as
services performed in connection with this lease.

         Section 3.09 - Indemnification of Lessor. Lessee covenants and agrees
that Lessor shall not be liable for any injuries or damages to persons,
entities, or property from any cause whatsoever by reason of the use,
occupation, control or enjoyment of the Demised Premises by Lessee, or any
person entering thereon for any reason or invited (other than Lessor or their
agents), suffered or permitted by Lessee to go or be thereon or holding under
Lessee at any time during the term of this lease, and Lessee will save and hold
harmless Lessor from and against any and all liability, penalties, damages,
expenses and judgments whatsoever on account of such injuries or damages. The
injuries and damages referred to in this paragraph shall include, without
limiting the generality of the preceding provisions, to injuries, damages and
mechanic's liens arising directly or indirectly out of any demolition, repairs,
restoration, reconstruction, changes, alterations and construction which Lessee
may make or cause to be made upon the Demised Premises or any part thereof.
Lessee, at Lessee's expense, agrees to employ legal counsel to defend any action
for which any claim shall be made for injuries or damages commenced against

         Section 3.10 - Compliance with Laws. The Lessee covenants that it will
during the demised term properly observe and at its own expense promptly comply
with and execute all present and future laws, rules, regulations and notices of
every nature and kind whatsoever of any governmental agency or authority
concerning the Demised Premises. It is expressly understood that the Lessee
shall have thirty (30) days or such time as said authorities shall accord, or
that Lessee shall necessarily need, within which to comply with, contest, obey,
carry out, observe and/or perform any such law, rule, regulation or notice.

coverage on the Demised Premises in solvent, mutual or stock companies or
company, insuring both the Lessor and the Lessee, in an amount and form
reasonably acceptable to the parties.

with the Limited Phase II Environmental Assessment Report dated June 17, 1998.
Lessor had any and all recommended cleanups recommended by the Limited Phase II
Environmental Assessment Report performed prior to Lessee's possession of the

out of or in any way relating to a breach of the environmental warranties made

fines, expenses, liabilities or losses arising during or after the lease term
out of or in any way relating to the presence, release or disposal of Toxic or

include costs incurred in connection with:

                  (i) the presence or suspected presence of Toxic or Hazardous
         Substances in the soil, groundwater or soil vapor on or under the
         Demised Premises resulting from any act or omission of Lessee;

                  (ii) the presence or suspected presence of Toxic or Hazardous
         Substances on or under the Demised Premises as a result of any

                                 EMINENT DOMAIN

         Section 6.01 - Eminent Domain. If more than twenty-five percent (25%)
of the land area of the Demised Premises is taken under the power of eminent
domain (including any conveyance made in lieu thereof), and such taking shall
make the operation of Lessee's business on the Demised Premises impractical,
then Lessee shall have the right to terminate this lease by giving Lessor
written notice of such termination within thirty (30) days after such taking or
condemnation. If Lessee does not so elect to terminate this lease, the rental to
be paid by Lessee hereunder shall be equitably reduced in proportion to Lessee's
loss of the use of the Demised Premises. Any award or awards payable on account
of any taking or condemnation of all or part of the Demised Premises shall be
payable to Lessor.

         default, but only if the party in default has not remedied such default
         within the said thirty (30) days or if the party in default has not
         commenced such act or acts as shall be necessary to remedy the default
         and shall complete such act or acts promptly; or

         (b) terminate this lease for the nonpayment of rent at any time after
         the expiration of ten (10) days following written notice to Lessee of
         nonpayment of such rent (provided each default has not been cured); and

         (c) any termination of this lease under sub-paragraphs (a) and (b) of
         this Section 7.01 shall not prejudice Lessor's right to prosecute any
         other remedy which it may have for a breach of this lease or default
         hereunder.

         Section 7.02 - Event of Default Defined. Each of the following shall be

                  (2) A petition or answer against Lessee seeking a
                  reorganization, arrangement, composition, readjustment,
                  liquidation, dissolution or other relief of the same or
                  different kind under any provision of the Bankruptcy Act;

                  (3) Adjudication of Lessee as a bankrupt or insolvent or

                  or part thereof upon execution, attachment or other process of
                  law or equity (except pursuant to a valid assignment or
                  sublease pursuant to Article VIII).

         Section 7.03 - Repossession. Upon termination of this lease as
hereinabove provided, or pursuant to statute, or by summary proceedings or
otherwise, the Lessor may enter forthwith without further demand or notice upon
any part of the Demised Premises, if it has not theretofore done so, and resume
possession either by summary proceedings, or by action at law or in equity or by
entry or otherwise as the Lessor may determine, and shall not be liable in
trespass or for any damages to Lessee or any other person. In no event shall
such re-entry or resumption of possession or reletting as hereafter provided be
deemed to be an acceptance or surrender of this lease or a waiver of the rights

of Lessee, and Lessee shall pay to Lessor on demand any amount properly paid by
Lessor including reasonable attorney fees for such purpose, with interest
thereon at the rate of ten percent (10%) per annum plus an additional service
fee of two percent (2%) from the date of payment thereof by Lessor.


<PAGE>   10

         Section 7.06 - Non-Exclusive Effect. The default provisions in this
Article VII shall not operate to exclude, override or limit any other right or
remedy provided in this lease, but shall be read in conjunction with the other
provisions hereof as supplementary thereto, and any election by the party for
whose benefit a particular provision operates, as communicated in any notice to
the other party, shall be conclusive as to the provision under which the former
is proceeding. Unless otherwise specified in such notice, however, any such
election shall not act as a waiver of the right to proceed under any other
provision at any other time with respect to the same or any other breach,
default, omission or failure of performance which may be the subject of the
election.

                                  ARTICLE VIII

and only while the Lessee is not in default.

                                   ARTICLE IX

                          TRANSFER OF LESSOR'S INTEREST

         Section 9.01 - Transfer of Lessor's Interest. In the event of the sale,
assignment or transfer by Lessor of its interest in the Demised Premises or in
this lease (other than a collateral assignment to secure a debt of Lessor) to a
successor in interest who expressly assumes the obligations of Lessor hereunder,
Lessor shall thereupon be released or discharged from all of its covenants and
obligations hereunder, except such obligations as shall have accrued prior to
any such sale, assignment or transfer; and Lessee agrees to look solely to such
successor in interest of Lessor for performance of such obligations. Lessor's
assignment of the lease or of any or all of its rights herein shall in no manner
affect Lessee's obligations hereunder. Lessee shall thereafter attorn and look
to such assignee, as Lessor, provided Lessee has first received written notice
of such assignment of Lessor's interest.

and from time to time upon not less than ten (10) days prior written request by
Lessor, to execute, acknowledge and deliver to Lessor, and Lessor agrees at any
time and from time to time, upon not less than ten (10) days prior written
request by Lessee, to execute, acknowledge and deliver to Lessee a statement in
writing certifying that this lease is unmodified and in full force and effect
(or if there have been mutually agreed upon modifications that the same is in
full force and effect, as modified, and stating the modifications), and the
dates to which the fixed rent and other charges have been paid in advance, if
any, and whether or not there is any existing default, other than on any
existing mortgage, by Lessee with respect to any sums of money required to be
paid by Lessee under the terms of this lease, or notice of default served by
Lessor, it being intended that any such statement delivered pursuant to this
paragraph may be relied upon by any prospective purchaser of the fee or
leasehold estate or by any prospective or existing mortgagee or assignee of any
mortgage upon the leasehold estate, or by any prospective assignee or subtenant
of the leasehold estate. If any such certification by Lessor shall allege
non-performance by Lessee, the nature and extent of such non-performance shall,
insofar as actually known by Lessor, be summarized therein. In the event that
either party shall fail to execute, acknowledge and deliver to the other each
statement prior to the expiration of said ten (10) day period, it shall be
conclusively presumed a certification that this lease is unmodified and in full
force and effect, that all rental has been paid to date and that there is no
existing default.

         Section 10.02 - Acknowledgment of Rent. The Lessor within ten (10)
days, upon request of the Lessee or any holder of a mortgage on the fee or
leasehold interest herein demised, will furnish a written statement duly
acknowledging the amount of rent and additional rent due, if any.
