NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of presentation

Consolidated Financial Statements

The accompanying unaudited consolidated financial statements of Willis Lease
Finance Corporation and its subsidiaries (the "Company") have been prepared
pursuant to the rules and regulations of the Securities and Exchange Commission
for reporting on Form 10-Q. Pursuant to such rules and regulations, certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted. The accompanying unaudited interim financial statements
should be read in conjunction with the audited consolidated financial statements
and notes thereto, together with Management's Discussion and Analysis of
Financial Condition and Results of Operations, contained in the Company's Annual
Report to Shareholders incorporated by reference in the Company's Annual Report
on Form 10-KA for the fiscal year ended December 31, 1996.

In the opinion of management, the accompanying unaudited consolidated financial
statements contain all adjustments (consisting of only normal and recurring
adjustments) necessary to present fairly the financial position of the Company
as of September 30, 1997, and December 31, 1996, and the results of its
operations for the three month and nine month periods ended September 30, 1997
and 1996 and its cash flows for the nine month periods ended September 30, 1997
and 1996. The results of operations and cash flows for the nine month period
ended September 30, 1997, are not necessarily indicative of the results of
operations or cash flows which may be reported for the remainder of 1997.

2. Management 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 disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenue and expenses during the reporting period. Actual
results could differ from those estimates.

During the quarter ended September 30, 1997, the Company recorded an allowance
for estimated returns of spare parts based on recent experience. Such returns
occur in the ordinary course of the Company's business.

3. Shares Issued

The Company's Employee Stock Purchase Plan (the "Purchase Plan") was adopted by
the Board of Directors on June 21, 1996. The Purchase Plan is designed to allow
eligible employees of the Company and participating subsidiaries to purchase
shares of Common Stock, at semi-annual intervals, through their periodic payroll
deduction under the Purchase Plan. The purchase price is the lesser of 85% of
the market price of the Common Stock at the beginning of each purchase interval
or 85% of the market price of the Common Stock at the end of each purchase
interval. A reserve of 75,000 shares of Common Stock has been established for
this purpose. During the nine month period ended September 30, 1997, the Company
issued 10,527 shares of Common Stock as a result of employee stock purchases
under the Purchase Plan.

Under the 1996 Stock Option/Stock Issuance Plan, 525,000 shares of the Company's
Common Stock were set aside to provide eligible persons with the opportunity to
acquire a proprietary interest in the Company. During the nine month period
ended September 30, 1997, 15,000 stock options were exercised in connection with
this agreement.

4. Financing

In February 1997, the Company obtained a new loan agreement for $41.5 million to
replace an existing loan of $44.2 million. The transaction resulted in an
extraordinary gain of $2 million or $0.36 per weighted average share, net of
tax. The new facility bears interest at LIBOR plus 2.5% and matures in February
1998. At that time, the Company has the option to extend the facility for an
additional six years.

In June 1997, the Company obtained a $15 million revolving credit facility to
finance the acquisition of engines and high-value spare parts for sale or lease.
In July 1997, the Company increased this facility to $30 million. This facility,
which expires on June 12, 1998, bears interest at prime plus 50 basis points and
may be renewed annually.

5. Subsequent event

On October 5, 1997, Western Pacific Airlines, Inc., a domestic lessee of three
engines with a combined net book value of $8.7 million filed a petition under
Chapter 11 of the Bankruptcy Code in the District of Colorado. Western Pacific
has 60 days from October 5, 1997, to agree to perform its obligations and to
cure any defaults under its leases with the Company. If Western Pacific does not
cure its defaults, the Company intends to repossess its engines. Although the
Company has not received any payments from Western Pacific in October 1997, the
Company has security deposits and prepaid rents totaling $284,500 relating to
these engines. At this time, the Company does not anticipate that the bankruptcy
will have a material adverse effect on the Company's financial position or
results of operations.

6. Earnings Per Share

For the purposes of calculating earnings per share, weighted average shares
outstanding includes the effect, if any, of outstanding options and warrants. 

7. Commitments

In June 1997, the Company committed to purchase nine aircraft engines. The
Company is obligated to purchase these engines by December 31, 1997. The
agreement provides that, to the extent that a purchased engine will be
overhauled by the seller, the payment of both the purchase price and the cost of
the overhauled engine will be deferred until the engine is overhauled and
delivered to the Company. It is not known at this time how many engines will be
overhauled. As of September 30, 1997, three of the nine engines subject to this
agreement have been purchased.

The Company has entered into commitments for the purchase of an aircraft for
disassembly by WASI, the purchase of two engines for the lease portfolio and the
purchase of three commuter aircraft with three spare engines for the lease
portfolio. The aggregate purchase price for these assets is $19.9 million and as
of September 30, 1997, deposits of $310,000 have been made in connection with
these purchases. The Company has arranged financing for one engine and is in the
process of arranging financing for the other purchases.

8.  New Accounting Pronouncement

In February 1997, the Financial Accounting Standards Board issued SFAS No. 128,
"Earnings per Share" which requires the Company to replace its presentation of
primary earnings per share with a presentation of basic earnings per share and
requires dual presentation of basic and diluted earnings per share on the face
of the income statement. The principal difference between primary earnings per
share under current accounting standards and basic earnings per share under the
new statement is that basic earnings per share does not consider common stock
equivalents such as stock options and warrants. Diluted earnings per share under
the new Statement will include potential dilution of convertible securities,
stock options and warrants. The Statement is effective for the Company's third
quarter of 1997 and requires restatement of all prior periods presented under
the new Statement. Basic earnings per share under the new Statement would have
been $.27 and $.13 for the three months ended September 30, 1997 and 1996, and
$1.05 and $.62 for the nine months ended September 30, 1997 and 1996. Diluted
earnings per share under the new Statement would have been $.26 and $.13 for the
three months ended September 30, 1997 and 1996, and $1.03 and $.62 for the nine
months ended September 30, 1997 and 1996.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS

OVERVIEW

The Company is engaged in the business of providing operating leases of
commercial jet aircraft engines and aircraft equipment and selling aircraft
engines and parts to air carriers and overhaul/repair facilities worldwide. The
Company's core business is acquiring and leasing commercial aircraft spare
engines and other aircraft equipment, primarily pursuant to operating leases. As
a significant corollary to its core business, the Company, through its
wholly-owned subsidiary Willis Aeronautical Services, Inc., ("WASI"),
specializes in the purchase and resale of aftermarket airframe and engine parts,
engines, modules and rotable components. The Company also engages in the
selective purchase and resale of commercial aircraft engines

Summary of Financial Results for the Quarter Ended September 30, 1997. Total
revenues for the quarter ending September 30, 1997, were $14.4 million, compared
to $7.3 million in the corresponding quarter of 1996. This increase resulted
from increased revenue due to a higher asset base and significantly higher spare
parts sales, offset by a slight decrease in sale of equipment acquired for
resale. Net income for the quarter ending September 30, 1997, was $1.5 million,
compared to $434,000 in the corresponding quarter of 1996.

Lease Portfolio. During the quarter ended September 30, 1997, eight engines were
added to the Company's lease portfolio at a total cost of $24.4 million and
three engines were sold.

Leasing Activities. Operating lease revenue for the three months ended September
30, 1997, increased 39% to $4.9 million from $3.5 million for the comparable
period in 1996. This increase reflects operating lease revenues from fourteen
additional engines and five spare parts packages acquired after September 30,
1996. In late June 1997, the Company entered into two finance leases. Finance
lease income generated from these transactions totaled $223,000 for the quarter
ended September 30, 1997. There were no comparable transactions as of September
30, 1996.

Expenses directly related to operating lease activity increased 71% to $3.3
million for the three months ended September 30, 1997, from the comparable
period in 1996. Interest expense increased 86% to $2.0 million for the three
months ended September 30, from the comparable period in 1996, due primarily to
an increased loan base and the replacement of the existing facility with a new
loan agreement in the first quarter of 1997 bearing a higher interest rate.
Residual sharing expenses increased 40% to $227,000 from the comparable period
in 1996. This expense is calculated by comparing the net book value of the
engines subject to such agreements to their related debt balances and adjusting
the residual share payable up or down to the appropriate amount representing the
sharing percentage of any excess of the net book value over the corresponding
debt balance for the five engines subject to residual sharing. Depreciation
expense increased 55% to $1.1 million for the three months ended September 30,
1997, from the comparable period in 1996, due to the larger asset base.


                                       10
<PAGE>   11

Gain on Sale of Leased Engines. During the quarter ended September 30, 1997, the
Company sold two engines from the lease portfolio. These engines had a net book
value of $4.4 million and they were sold for a gain of $936,000. Maintenance
deposits collected on one of these engines were not required to be refunded to
the lessee or remitted to the seller and are included in the gain. There were no
sales of leased engines for the quarter ended September 30, 1996.

Spare Parts Sales. Revenues from spare parts sales increased 542% from $869,000
to $5.6 million compared to the three months ended September 30, 1996, due
primarily to the acquisition of three engines in the second and third quarters
of 1997 and the subsequent sale of parts from these engines. The gross profit,
before interest expense, decreased to 28% from 75% in the corresponding period
in 1996. The Company does not believe that the relatively high margin in 1996 is
indicative of future results.

Sale of Equipment Acquired for Resale. During the three months ended September
30, 1997, the Company sold one engine for $1.9 million which resulted in a gain
of $500,000, plus four engines acquired at a cost of $600,000 and sold for a
gain of $100,000. During the three months ended September 30, 1996, the Company
sold two engines for $2.8 million, resulting in a loss of $200,000 due to higher
than expected overhaul costs on the engines.

Interest and Other Income. Interest and other income decreased to $91,000 from
$150,000 for the three months ended September 30, 1996. This is a result of less
cash on deposit earning interest.

General and Administrative Expenses. General and administrative expenses
increased 83% to $2.4 million for the three months ended September 30, 1997,
from $1.3 million in the comparable period in 1996. This increase reflects
expenses associated with staff additions, increased rent due to the expansion of
the WASI facility, as well as an increase in professional fees, insurance
expense and public company costs incurred by the Company in 1997. As of
September 30, 1997, the Company has 40 full-time and 4 part-time employees,
compared to 1 part-time and 24 full-time employees as of September 30, 1996.

Income Taxes. Income taxes for the three months ended September 30, 1997,
increased to $970,000 from $300,000 in the comparable period in 1996. This
increase reflects an increase in the Company's pre-tax earnings.

Lease Portfolio. During the first nine months of 1997, sixteen engines and five
spare parts packages were added to the Company's lease portfolio at a total cost
of $52.8 million. Five engines were sold from the portfolio.

Leasing Activities. Operating lease revenue for the nine months ended September
30, 1997, increased 30% to $13.5 million from $10.4 million from the comparable
period in 1996. This increase reflects lease revenues from additional engines
and spare parts packages acquired after September 30, 1996. In late June 1997,
the Company entered into two finance leases. Finance lease income generated from
these transactions totaled $223,000 for the nine months ended September 30,
1997. There were no comparable transactions as of September 30, 1996.

Expenses directly related to operating lease activity increased 37% to $8.6
million. Interest expense increased 55% to $5.0 million for the nine months
ended September 30, 1997, from the comparable period in 1996, due primarily to
an increased loan base and the replacement of the existing facility with a new
loan agreement in the first quarter of 1997 bearing a higher interest rate.
Depreciation expense increased 18% to $2.9 million for the nine months ended
September 30, 1997, from the comparable period in 1996, due to the larger asset
base in 1997. Residual sharing expense increased 12% to $598,000 for the nine
months ended September 30, 1997, from the comparable period in 1996, due to the
larger asset base in 1997. This expense is calculated by comparing the net book
value of the engines subject to such agreements to their related debt balances
and adjusting the residual share payable up or down to the appropriate amount
representing the sharing percentage of any excess of the net book value over the
corresponding debt balance for the five engines subject to residual sharing.

Gain on Sale of Leased Engines. During the nine months ended September 30, 1997,
the Company sold three engines from the lease portfolio. These engines had a net
book value of $6.1 million and they were sold for a gain of $1.3 million. There
were no sales of leased engines for the nine months ended September 30, 1996.

Spare Parts Sales. Revenues from spare parts sales increased 247% to $11.5
million. The gross margin decreased to 32% in 1997 from 51% in the 
corresponding period in 1996. The Company does not believe that the relatively
high margin in 1996 is indicative of future results.

Sale of Equipment Acquired for Resale. During the nine months ended September
30, 1997, the Company sold 10 engines for $12.7 million which resulted in a gain
of $2.1 million, compared to the nine months ended September 30, 1996, during
which the Company sold five engines for $9.6 million resulting in a gain of $1.1
million. Included in the 1997 sales was one transaction involving the sale of
four engines acquired at a cost of $600,000 and sold for a gain of $100,000.

Interest and Other Income. Interest and other income for the nine months ended
September 30, 1997, increased to $544,000 from $197,000 for the nine months
ended September 30, 1996. This is a result of interest earned on deposits held,
primarily the proceeds from the Company's initial public offering.

General and Administrative Expenses. General and administrative expenses
increased 85% to $6.4 million for the nine months ended September 30, 1997, from
the comparable period in 1996. This increase reflects expenses associated with
staff additions, increased rent due to the expansion of the WASI facility, as
well as an increase in professional fees, insurance expense and public company
costs.

Income Taxes. Income taxes for the nine months ended September 30, 1997,
increased to $2.5 million from $1.4 million for the comparable period in 1996.
This increase reflects an increase in the Company's pre-tax earnings.

Extraordinary Item. In February 1997, the Company obtained a new loan agreement
for $41.5 million to replace the existing note of $44.2 million. The transaction
resulted in an extraordinary gain of $2 million, net of tax, or $.36 per
weighted average share.

LIQUIDITY AND CAPITAL RESOURCES

In September 1997, the Company financed two engines using its $15 million
financial program with Fleet Capital Corporation. The total amount borrowed 
was $6.3 million with interest rates varying from 8.9% to 10%.

At September 30, 1997, $66.6 million of the Company's borrowings were on a
variable rate basis, at various interest rates tied to either LIBOR or the Prime
rate. The Company's equipment leases are generally structured at fixed rental
rates for specified terms. To date, these variable rate borrowings have resulted
in lower interest expense for the Company. In September 1996, the Company
purchased an amortizing interest rate cap from an investment grade financial
institution (the "Counter Party") to limit its exposure to increases in interest
rates on a portion of its variable rate borrowings. Pursuant to this cap, the
Counter Party will make payments to the Company, based on the notional amount of
the cap, if the three month LIBOR rate is in excess of 7.66%. As of September
30, 1997, the notional principal amount of the cap was $37.2 million and said 
amount will decline to $26 million at the end of its term. The cost of the cap
is being amortized as an expense over a four year period. The Company will be
exposed to credit risk in the event of non-performance by the Counter Party. 
Increases in interest rates could narrow or eliminate the spread, or result in 
a negative spread, between the rental revenue the Company realizes under its
leases and the debt service that the Company pays under its floating rate
borrowings.

As of September 30, 1997, the Company had four engines and three spare parts
packages which had not been financed. The Company will seek permanent
financing for this equipment, although no assurance can be given that such
financing will be available on favorable terms, if at all. In addition, certain
of the Company's engines have been financed under floating rate facilities.
Until fixed rate financing for these assets is in place, the Company is subject
to interest rate risk if interest rates increase, since the underlying lease
revenue is fixed.

The Company has received a letter of commitment from a financial institution to
provide an $80 million warehouse facility to a special purpose subsidiary of the
Company, for the financing of jet aircraft engines to be transferred by the
Company to such finance subsidiary. The facility will become available
immediately upon completion of definitive agreements. This transaction's
structure is intended to facilitate future public or private securitized note
issuances by the special purpose subsidiary. This facility is expected to have
an eight year term and to bear interest at LIBOR plus 225 basis points. This
facility requires the issuer to hedge 50% of this facility against interest rate
changes.

The Company believes that its current and anticipated credit facilities and
internally generated funds and cash on hand should be sufficient to fund the
Company's anticipated operations for the immediate future. The Company
anticipates that it will also need to raise additional equity capital to
continue its growth.

The Company's ability to successfully execute its business strategy is 
dependent in part on its ability to raise equity capital and to obtain debt
capital. There can be no assurance that the necessary amount of such equity or
debt capital will continue to be available to the Company on favorable terms, or
at all. If the Company were unable to obtain any portion of required financing
on favorable terms, the Company's ability to add new engines and parts packages
to its portfolio or to conduct profitable operations with its existing asset
base would be impaired, which would have a material adverse effect on the
Company's business, financial condition and results of operations.

In June 1997, the Company committed to purchase nine aircraft engines. The
Company is obligated to purchase these engines by December 31, 1997. The
agreement provides that, to the extent that a purchased engine will be
overhauled by the seller, the payment of both the purchase price and the cost of
the overhauled engine will be deferred until the engine is overhauled and
delivered to the Company. It is not known at this time how many engines will be
overhauled. As of September 30, 1997, three of the nine engines subject to this
agreement have been purchased.

The Company has entered into commitments for the purchase of an aircraft for
disassembly by WASI, the purchase of two engines for the lease portfolio and the
purchase of three commuter aircraft with three spare engines for the lease
portfolio. The aggregate purchase price for these assets is $19.9 million and as
of September 30, 1997, deposits of $310,000 have been made in connection with
these purchases. The Company has arranged financing for one engine and is in the
process of arranging financing for the other purchases.

FACTORS THAT MAY AFFECT FUTURE RESULTS

In addition to other information in this Report, the following risk factors
should be considered carefully by potential purchasers in evaluating an
investment in the Common Stock of the Company. Except for historical information
contained herein, the discussion in this Report contains forward-looking
statements that involve risks and uncertainties, such as statements of the
Company's plans, objectives, expectations and intentions. The cautionary
statements made in this Report should be read as being applicable to all related
forward-looking statements wherever they appear in this Report. The Company's
actual results could differ materially from those discussed here. Factors that
could cause or contribute to such differences include those discussed below, as
well as those discussed elsewhere herein and in the Company's report on Form
10-KA for the year ended December 31, 1996.

The Company leases its portfolio of aircraft equipment and spare parts packages
(collectively "Aircraft Equipment") primarily under operating leases. Operating
leases require the Company to re-lease or sell Aircraft Equipment in its
portfolio in a timely manner upon termination of the lease in order to minimize
off-lease time and recover its original investment in the Aircraft Equipment.
Numerous factors, many of which are beyond the control of the Company, may have
an impact on the Company's ability to re-lease or sell Aircraft Equipment on a
timely basis. Among the factors are general market conditions, regulatory
changes (particularly those imposing environmental, maintenance and other
requirements on the operation of aircraft engines), changes in the supply or
cost of the Aircraft Equipment and technological developments. Further, the
value of a particular used aircraft engine varies greatly depending upon its
condition, the number of hours remaining until the next major maintenance of the
aircraft engine is required and general conditions in the airline industry. In
addition, the success of an operating lease depends in part upon having the
Aircraft Equipment returned by the lessee in marketable condition as required by
the lease. Consequently, there can be no assurance that the Company's estimated
residual value for the Aircraft Equipment would be realized. If the Company is
unable to re-lease or sell the Aircraft Equipment on favorable terms, its
business, financial condition, cash flow, ability to service debt and results of
operations could be adversely affected.

The Company through WASI, also acquires aviation equipment such as whole engines
or airframes which can dismantled and sold as parts. Before parts may be
installed in an aircraft, they must meet certain standards of condition
established by the Federal Aviation Administration ("FAA"). Parts must also be
traceable to sources deemed acceptable by the FAA. Parts owned by the Company
may not meet applicable standards or standards may change, causing parts which
are already in the Company's inventory to be scrapped or modified. Engine
manufacturers may also develop new parts to be used in lieu of parts already
contained in the Company's inventory. In all such cases, to the extent the
Company has such parts in its inventory, their value may be reduced. In
addition, if the Company did not sell airframe and engine component parts that
it purchases soon after acquisition, the Company would be subject to all the
risks of ownership described above.

The Company also engages in the selective purchase and resale of commercial
aircraft engines and engine components in the aftermarket. On occasion, the
Company purchases engines or components without having a commitment for their
sale or lease. If the Company purchased an engine or components
without having a firm commitment for their sale or if a firm commitment for sale
were to exist but not be consummated for whatever reason, the Company would be
subject to all the risks of ownership described above.

The Company would be affected by downturns in the air transportation industry in
general. In particular, substantial increases in fuel costs or interest rates,
increasing fare competition, slower growth in air traffic, or any significant
downturn in the general economy could adversely affect the air transportation
industry and may therefore negatively impact the Company's business, financial
condition and results of operations.

A lessee may default in performance of its lease obligations and the Company may
be unable to enforce its remedies under a lease. The Company's inability to
collect receivables under a lease or to repossess Aircraft Equipment in the
event of a default by a lessee could have a material adverse effect on the
Company's business, financial condition or results of operations. In most cases
where a debtor seeks protection under Chapter 11 of the United States Bankruptcy
Code (the "Bankruptcy Code"), creditors are automatically stayed from enforcing
their rights. In the case of United States certified airlines, Section 1110 of
the Bankruptcy Code provides certain relief to lessors of the aircraft
equipment. Specifically, the airline has 60 days from the date the airline seeks
protection under Chapter 11 of the Bankruptcy Code to agree to perform its
obligations and to cure any defaults. If it does not do so, the lessor may
repossess the aircraft equipment. The scope of Section 1110 has been the subject
of significant litigation and there can be no assurance that the provisions of
Section 1110 will protect the Company's investment in an aircraft engine in the
event of a lessee's bankruptcy. In addition, Section 1110 does not apply to
lessees located outside of the United States and applicable foreign laws may not
provide comparable protection.


                                       15
<PAGE>   16
 The Company has experienced fluctuations in its quarterly results and
anticipates that these fluctuations may continue. Such fluctuations may be due
to a number of factors, including the timing of acquisitions and sales of
engines and spare parts and engine marketing activities, unanticipated early
lease terminations or default by a lessee. Given the possibility of such
fluctuations, the Company believes that comparisons of the results for preceding
quarters are not necessarily meaningful and that results for any one quarter
should not be relied upon as an indication of future performance. In the event
the Company's revenues or earnings for any quarter are less than the level
expected by securities analysts or the market in general, such shortfall could
have an immediate and significant adverse impact on the market price of the
Company's Common Stock.

In 1996, approximately 61% of the Company's lease revenue was generated by
leases to foreign customers. During the nine months ended September 30, 1997,
approximately 64% of the Company's lease revenue was generated by leases to
foreign customers. Such leases may present greater risks to the Company because
certain foreign laws, regulations and judicial procedures may not be as
protective of lessor rights as those which apply in the United States. In
addition, many foreign countries have currency and exchange laws regulating the
international transfer of currencies. To date, the Company has experienced some
collection problems under certain leases with foreign airlines, and there can be
no assurance that the Company will not experience such collection problems in
the future. The Company may also experience collection problems related to the
enforcement of its lease agreements under foreign local laws and the attendant
remedies in such locales. Consequently, the Company is subject to the timing and
access to courts and the remedies local laws impose in order to collect its
lease payments and recover its assets.

In some circumstances, the Company acquires and leases assets before it has
secured debt financing. There can be no assurance that debt financing will be
available after the asset has been acquired or, if available, at attractive
rates or terms. Factors that could cause debt financing to be more expensive or
unavailable include changes in interest rates, financial conditions of the
lessee or the Company, prospects for the airline industry or the asset type as
well as general economic conditions. If debt financing is not available, a like
amount of the Company's equity capital would be unavailable for use to acquire
additional assets, which could have a material adverse effect on the Company's
business, financial condition and results of operations.

The Company has recently experienced significant growth in revenues. Such growth
has placed, and is expected to continue to place, a significant strain on the
Company's managerial, operational and financial resources. Due to the Company's
rapid pace of growth over the past year, the Company hired three new officers
(an Executive Vice President and Chief Administrative Officer, an Executive Vice
President and Chief Financial Officer and a Senior Vice President and General
Counsel) during the four months prior to September 30, 1997. There can be no
assurance that the Company will be able to effectively manage the expansion of
its operations, or that the Company's systems, procedures or controls will be
adequate to support the Company's operations. An inability to effectively manage
growth could have a material adverse effect on the Company's business, financial
condition and results of operations.

One of the components of the Company's growth strategy is the selected
acquisition of businesses complementary to the Company's existing businesses and
possible expansion into new aviation-related activities. The inability of the
Company to identify suitable acquisition candidates or to complete acquisitions
on reasonable terms could adversely affect the Company's ability to grow. In
addition, any acquisition or expansion made by the Company may result in
potentially dilutive issuances of equity securities, the incurrence of
additional debt and the amortization of expenses related to goodwill and other
intangible assets. The Company also may experience difficulties in the
assimilation of operations, services, products and personnel, an inability to
sustain or improve historical revenue levels, the diversion of management's
attention from ongoing business operations and the potential loss of key
employees. Any of the foregoing could have a material effect on the Company's
financial condition, results of operations and prospects.

August 14, 1997 (Continued)

                    Engine Record Data To Be Provided To WLFC

      1.    Bill of Sale for each Engine.

      2.    Letter and documentation stating the reason for removal of each
            Engine which shall  include a Form 8130-3 or JAA Form.

      3.    Life Limited parts sheet signed by Air India for each Engine.

      4.    Material Certification form from Air India and/or PW for each
            Engine, as applicable.

      5.    Log sheet defining any work performed by Air India on each Engine.

      6.    Documentation and verification defining the preservation performed
            on each Engine to ensure that the Engine(s) are preserved to Pratt &
            Whitney specifications prior to Delivery.

      On behalf of WLFC, PWES will put forward reasonable efforts to obtain any
      of the above Engine Documentation that WLFC requires from Air India.
      Additionally, PWES shall provide copies of the Pratt & Whitney original
      build documentation for each Engine.

2.5   PWES will be under no obligation to ship an Engine if there is a previous
      invoice outstanding by WLFC to PW which exceeds PW's outstanding invoice
      balance to WLFC.

2.6   Within at least fifteen (15) days prior to Delivery notification of any
      specified Engine described in this Agreement by WLFC to PW, WLFC and PW
      shall mutually agree whether each Engine to be Delivered shall be either
      leased or disposed of for its modules and component parts. PW shall be
      granted by WLFC the "right of first refusal" to lease each such Engine as
      Delivery notification is exercised by WLFC. When a lease is mutually
      agreed to by the parties, the Lease Support Agreement by and between WLFC
      and PW shall govern. When WLFC determines that a PW engine as described in

      of WLFC or its affiliates (such PW Engine being referred to as an
      unserviceable Engine), WLFC will dispose of such Engine(s), and the
      modules, parts and components thereof in accordance with the Engine
      Disposition Agreement.

2.7   PW shall provide, at no-charge to WLFC, four (4) PW engine data plates to
      allow whatever four (4) engines, as described in this Agreement or

      which shall exclude the programming plugs. WLFC shall return

      WLFC shall so identify the subject first two (2) Engines by serial number
      from the Engines specified in this Agreement at the time of or prior to
      the delivery to WLFC to which Engines the data plates shall be assigned.
      WLFC shall cause each of the subject first two (2) Engines to be
      overhauled and modified by PW at PW's Cheshire, Connecticut facility to
      the PW4060 thrust rating. It is contemplated that the third and fourth
      engines that WLFC selects at its sole discretion, whether part of this
      Agreement or otherwise, may be, but not necessarily, overhauled or
      modified by PW's Cheshire Connecticut facility. This data plate
      provisioning has an estimated value of Three Hundred and Forty-Seven
      Thousand, Eight Hundred Dollars ($347,800.00) per Engine to WLFC.

2.8   PW shall grant WLFC the "right of first refusal" to competitively bid on
      the purchase of PW engine serial number 727391, if PW decides to sell said

      customs or other duties which are based upon the purchase and sale or any
      subsequent use, operation or possession of the Engine (the "Taxes"),
      exclusive of taxes on or measured by PWES's income. WLFC shall promptly
      remit to PWES or the proper taxing authority and shall indemnify, defend
      and hold PWES, its officers, employees and directors, harmless for and
      against all such Taxes, interest and penalties assessed, and reasonable
      attorneys' fees incurred in connection with the payment or collection of
      such Taxes.

      (b)   The provisions of this Article 3.0 shall survive the completion of
            the transactions contemplated by this Agreement and its earlier
            cancellation or termination.

              ARTICLE 4.0 - INSPECTION, DELIVERY, TITLE, RISK OF LOSS

      bank that the payment has been received in accordance with Article 2.0

      Engine.

      (b)   Upon Delivery of the Engine to WLFC, WLFC shall bear full risk of

            Engine Inspection Acknowledgment Receipt, WLFC shall be responsible
            for any technical discrepancies in the Engine and the Engine
            Documentation which it has accepted.

      (c)   Title to each Engine shall pass to WLFC upon Delivery.

<PAGE>   12

Loan only to refinance the Debtor's purchase of the Engine.

        2.5 Increased Costs. If any change in any law, regulation or treaty, or
in the interpretation or administration thereof, or compliance by the Lender
with any request or directive (whether or not having the force of law) of any
authority charged with the interpretation or administration thereof, shall in
the reasonable determination of the Lender:

        (a) subject the Lender to any tax, levy or other governmental charge
with respect to the Loan or its obligation to make or maintain the Loan or
change the basis of taxation of payments by the Debtor to the Lender in respect
of the Loan (other than any tax on or measured by the overall net income of the
Lender); or

        (b) impose, modify or hold applicable any reserve, special deposit or
similar requirement against assets of, deposits or other liabilities of or for
the account of, or loans or commitments by, the Lender with respect to the Loan
(including without limitation any reserves against "Eurocurrency Liabilities"
under Regulation D of the Board of Governors of the Federal Reserve System); or

         (c) impose on the Lender any other condition with respect to the Loan
or its obligation to make and maintain the Loan; and the result of any of the
foregoing is to increase the cost to the Lender of making or maintaining such
Loan or to reduce the amount of any sum received or receivable by the Lender
under this Agreement or the Note issued to the Lender, then the Debtor shall pay
to the affected Lender on demand from time to time such additional amounts as
may be necessary to reimburse the Lender for such increased cost or to
compensate the Lender for such reduced amount; provided, however, that upon the
Debtor's payment of such increased cost or compensation to the Lender, the
Debtor shall have the option to prepay the Note in full at the time of its
payment of any such increased cost or compensation with no prepayment penalty at
such time only. A certificate, calculating in reasonable detail the amount of
such increased cost or reduced amount, shall be submitted to the Debtor by any
affected Lender, and shall, absent manifest error, be final, conclusive and
binding for all purposes.

        2.6 Capital Adequacy. If any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any governmental agency or
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Lender with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, in 



                                       12
<PAGE>   13

the Lender's reasaonable determination (which determination shall be conclusive
and binding) has the effect of increasing the amount of capital required to be
maintained by the Lender or reducing the rate of return on capital as a
consequence of its agreement to make, or its making of, the Loan pursuant to
this Agreement to a level below that which the Lender could have achieved but
for such adoption, change or compliance (taking into consideration policies with
respect to capital adequacy) by an amount reasonably deemed by the Lender to be
material, then, upon demand by the Lender, the Debtor shall pay to the Lender,
from time to time as specified by the Lender, such additional amounts which
shall be sufficient to compensate the Lender for the cost of such additional
capital or reduced rate of return; provided, however, that upon the Debtor's
payment of such additional amounts or compensation to the Lender, the Debtor
shall have the option to prepay the Note in full at the time of its payment of
any such additional amounts or compensation with no prepayment penalty at such
time only. A certificate calculating in reasonable detail the amount of any such
cost or reduced rate of return, submitted to the Debtor by any such affected
Lender, shall, absent manifest error, be final, conclusive and binding for all
purposes.

        2.7 Illegality. In the event that the Lender shall have reasonably
determined that the making or continuation of the Loan is or has become unlawful
or interferes with or prevents compliance by the Lender in good faith with any
applicable law, governmental rule, regulation, guideline or order (whether or
not having the force of law or whether or not failure to comply therewith would
be unlawful), the Lender shall promptly give notice to the Debtor of such
determination. The Debtor shall, on the next Installment Payment Date after
notice of any such determination or earlier if required by law, repay the entire
Loan, together with all interest accrued thereon and all other amounts payable
hereunder and under the Note with no prepayment penalty at such time only.

        2.8 Funding Losses. If the Debtor fails to fulfill the conditions set
forth in Sections 2.5, 2.6, and/or 2.7 of this Agreement by the time specified
for their fulfillment or otherwise fails to borrow the Loan after delivering a
notice with respect thereto, then the Debtor shall pay the Lender the amount of
any losses, costs and expenses reasonably incurred as a consequence thereof,
including any loss of margin or expenses incurred in liquidating or re-employing
deposits or other funds acquired to make such Loan. A certificate, calculating
in reasonable detail the amount of any such losses, costs and expenses,
submitted to the Debtor shall, absent manifest error, be final, conclusive and
binding for all purposes.

        2.9 Method of Payment. The Debtor shall make each payment due under this
Agreement and under the Note to the Lender at its 



                                       13

time to time (including, without limitation, any time at which any amount is due
under this Agreement) any amount due under this Agreement or the Note,
including, without limitation, principal, interest, fees and charges, against
any account of the Debtor with the Lender (other than any payments or amounts
held in the Account which are solely Maintenance Fees or Security Deposits which
payments or amounts shall be disbursed pursuant to the terms of Sections 9.1(b),
9.1(c) and/or 10.13 of this Agreement). Whenever any payment to be made under
this Agreement or under the Note shall be stated to be due on a Saturday, Sunday
or a public holiday, or the equivalent for banks generally under the laws of the
State of Rhode Island or California, such payment shall be made on the next
succeeding Business Day, and such extension of time shall be included in the
computation of the payment of interest.

                Parts; Additions, Modifications; Identification; Event of Loss
                re Engine.

        (a) Maintenance and Operation. Debtor, at its own cost and expense,
shall (or shall cause the Lessee to) (i) maintain, inspect, service, repair,
overhaul and test the Engine in accordance with the manufacturer's maintenance
program and (w) an FAA approved Part 121 maintenance program, (x) all
maintenance manuals initially furnished with the Engine, if any, including any
subsequent amendments or supplements to such manuals issued by the applicable
manufacturer from time to time, (y) all "mandatory", "alert" and (to the extent
applicable to Debtor, or its operations) "highly recommended" or other service
bulletins, modification kits, and similar notices and components issued,
supplied, or available by or through the manufacturer and/or the manufacturer(s)
of the Engine or Part with respect to the Engine and (z) all "airworthiness
alerts" and "Airworthiness" or other "Directives", "Service Letters",
"Circulars" and "Operator Bulletins" and all other applicable service,
maintenance, repair and overhaul regulations issued by the FAA or similar
regulatory agency having jurisdictional authority, and whenever possible causing
compliance to the foregoing to be completed through corrective modification in
lieu of operating manual restrictions; (ii) maintain all Records and all other
records, logs, and other materials required by the FAA to be maintained in
respect of the 



                                       30

Engine, or by the manufacturer thereof for enforcement of any warranties.
Without limiting the generality of the foregoing, Debtor shall (or shall cause
the Lessee to) maintain, inspect, service, repair, overhaul and test the Engine,
and furnish all parts, replacements, mechanisms, devices and servicing required
therefor, so that the value, condition and operating efficiency of the Engine
shall at all times be maintained and preserved at a level which is the higher
of, (x) its value, condition and operating efficiency when delivered to Debtor,
fair wear and tear excepted, or (y) the level required by any governmental
authority having jurisdiction with respect thereto, or as shall be required by
any and all applicable "airworthiness alerts" and "Airworthiness" or other
"Directives", "Service Letters", "Circulars" and "Operator Bulletins". All
maintenance procedures required under this Section 5.11(a) or any other
provision of this Agreement shall be undertaken and completed in accordance with
all FAA standards and procedures and all manufacturer recommended procedures, as
well as the procedures established by Debtor for similar engines which it owns
or leases, and only by properly trained, licensed, and certified maintenance
sources and maintenance personnel, so as to keep the Engine in good operating
condition, ordinary wear and tear alone excepted. Debtor shall not (and shall
cause the Lessee not to) permit the Engine to be serviced, repaired, maintained,
used or operated in any manner contrary to directives of the FAA or the
manufacturer's operating manuals or instructions, or in violation of the
manufacturer's specifications, service bulletins or other requirements,
including, without limitation, such of the manufacturer's requirements as may be
applicable to keep in full force and effect each warranty, product or
performance guaranty, service life policy or the like. Notwithstanding anything
contained in this Section 5.11(a) to the contrary, so long as the Debtor shall
(or cause the Lessee to) maintain, inspect, service, repair, overhaul and test
the Engine (and maintain and keep any Records) at a level which fully satisfies
in all respects the terms and conditions of the Lease, the Debtor shall be
deemed to have complied in all respects to the terms and conditions of this
Section 5.11(a).

        (b) Compliance and Use. The Engine shall be maintained, used and
operated by Debtor (or the Debtor shall cause the Lessee to) maintain, use and
operate the Engine, in compliance with any and all statutes, laws, ordinances,
regulations and mandatory standards, letters, circulars, bulletins, instructions
or directives issued by any governmental agency applicable to the maintenance,
use or operation thereof, in compliance with any certificate, license or
registration relating to the Engine issued by any agency, and in a manner that
does not modify or impair any existing warranties on the Engine or any part
thereof. Debtor shall also (or shall cause the Lessee to) operate the Engine
solely in the conduct of its business and/or for commercial purposes, and Debtor
shall not (and shall cause the Lessee not to) operate or permit the Engine to be
operated at any time or in any 



                                       31
<PAGE>   32

geographic area when or where insurance required by the provisions of Section
5.12 hereof shall not be in effect or excluded from coverage, or in any
recognized or threatened area of hostilities unless fully covered to Lender's
satisfaction by hull, war, and political risk insurance, or any area in which
Lender's first lien on the Engine may be jeopardized or not recognized, as
determined in Lender's sole judgment, or in a manner, for any time period, such
that, any third party shall be deemed to have "operational control" of the
Engine, except for the Lessee pursuant to the terms of the Lease.
Notwithstanding anything contained in this Section 5.11(b) to the contrary, so
long as the Debtor shall (or cause the Lessee to) use, operate, maintain,
inspect, service, repair, overhaul and test the Engine (and maintain and keep
any Records) at a level which fully satisfies in all respects the terms and
conditions of the Lease, the Debtor shall be deemed to have complied in all
respects to the terms and conditions of this Section 5.11(b).

        (c) Identification. If requested by Lender in writing, Debtor shall, at
its own cost and expense (or the Debtor shall cause the Lessee, at the Lessee's
own cost and expense to), attach to the Engine a data plate satisfactory to
Lender disclosing Lender's security interest in the Engine.

        (d) Replacement Parts. Debtor, at its own cost and expense, will
promptly (or will cause the Lessee to promptly) replace all Parts which may from
time to time become worn out, lost, stolen, taken, destroyed, seized,
confiscated, requisitioned, damaged beyond repair or permanently rendered or
declared unfit for use for any reason whatsoever (such substituted Parts
hereinafter called "Replacement Parts"). In addition, in the ordinary course of
maintenance, service, repair, overhaul or testing, Debtor may, at its own cost
and expense, (or may cause the Lessee to promptly) remove serviceable Parts,
provided that Debtor shall, at its own cost and expense (or Debtor shall cause
the Lessee, at the Lessee's own cost and expense to), replace such serviceable
Parts as promptly as practicable. All Replacement Parts (i) shall be owned by
Debtor or Lessee free and clear of all Liens (other than the Lien of the Lender
hereunder), (ii) shall be in an airworthy condition and of at least equivalent
model and modification status and/or service bulletin accomplishment status,
shall be fully interchangeable as to form, fit and function and shall be in a
good operating condition as, and shall have a value and utility at least equal
to, the Parts replaced assuming such replaced Parts were in the condition and
repair required to be maintained by the terms hereof, (iii) shall have a current
"serviceable tag" of the manufacturer or maintenance facility providing such
items to Debtor or Lessee, indicating that such Parts are new, serviceable or
overhauled, (iv) if serviceable, shall have all maintenance records from the
last overhaul thereof and the maintenance history since the last overhaul
thereof, (v) if overhauled, have all overhaul records, and (vi) if a life
limited Part, have continuous 



                                       32
<PAGE>   33

records since the date of manufacture or the date of the last overhaul. All
Parts at any time removed from the Engine shall remain part of the Collateral,
no matter where located, until such time as such Parts shall be replaced by
Parts which have been incorporated or installed in or attached to the Engine and
which meet the requirements for Replacement Parts specified above. Without
limiting the generality of any term of this Agreement, immediately upon any
Replacement Part becoming incorporated or installed in or attached to the Engine
as above provided, without further act, such Replacement Part shall become
subject to this Agreement including, without limitation, the lien and security
interest of this Agreement, and shall be deemed part of the Collateral and shall
be deemed part of the Engine, as the case may be, for all purposes hereof to the
same extent as the Parts originally incorporated or installed in or attached to
the Engine, and the Lender's lien and security interest with respect to the Part
being replaced by the Replacement Part shall automatically thereafter be deemed
to be released and shall no longer be subject to the terms of this Agreement.
Notwithstanding anything contained in this Section 5.11(d) to the contrary, so
long as the Debtor shall (or cause the Lessee to) use, operate, maintain,
inspect, service, repair, overhaul and test the Engine and replace any Parts
(and maintain and keep any Records) at a level which fully satisfies in all
respects the terms and conditions of the Lease, the Debtor shall be deemed to
have complied in all respects to the terms and conditions of this Section
5.11(d).

        (e) Additions; Modifications. Debtor (or the Lessee) shall be entitled
from time to time during the term of this Agreement to, at Debtor's or Lessee's
sole cost and expense, make such alterations, modifications, additions to or
removals from any Engine or Engine as may be reasonable in the proper conduct by
Debtor (or the Lessee, as applicable) of its business; provided, that in no
event shall any such alteration, modification, addition or removal (i) impair
the originally intended function or use of the Engine or diminish the use,
condition or value of the same, assuming the Engine was in the condition and
repair then required to be maintained by the terms hereof, and/or (ii) as to any
Additional Parts (as such term is defined below), the removal of any such
Additional Parts can be readily removed without causing material damage to the
Engine. All Parts incorporated or installed in or attached to the Engine as the
result of such alteration, modification or addition shall be collectively
referred to as the "Additional Parts". Debtor shall (or shall cause the Lessee
to) repair all damage to the Engine resulting from any installation and/or
removal of any Additional Parts so as to restore the Engine to its condition
prior to installation, normal wear and tear excepted assuming the Engine was in
the condition and repair then required to be maintained by the terms hereof. Any
alterations or modifications with respect to the Engine that may at any time
during the term of this Agreement be required to comply with applicable law or
any governmental rule or regulation shall be 



                                       33
<PAGE>   34

made at the sole cost and expense of Debtor or Lessee, as applicable. Without
limiting the generality of any term of this Agreement, immediately upon any
Additional Parts becoming incorporated or installed in or attached to the Engine
as above provided, without further act, such Additional Parts shall become
subject to this Agreement including, without limitation, the lien and security
interest of this Agreement, and shall be deemed part of the Collateral and shall
be deemed part of the Engine, as the case may be, for all purposes hereof to the
same extent as the Parts originally incorporated or installed in or attached to
the Engine; provided, that if such Additional Part was in addition to, and not a
replacement of or substitution for, any Part incorporated or installed in or
attached or added to the Engine on the date the Engine became subject to the
terms of this Agreement (a "Debtor Additional Part"), Debtor may (or may cause
the Lessee to) at any time remove such Debtor Additional Part from the Engine so
long as the removal of such Debtor Additional Part (i) does not impair the
originally intended function or use of the Engine or diminish the use, condition
or value of the same, assuming the Engine was in the condition and repair then
required to be maintained by the terms hereof, and/or (ii) can be readily
removed without causing material damage to the Engine, and upon removal of such
Debtor Additional Part, Lender's lien and security interest with respect to such
Debtor Additional Part shall automatically be deemed to be released and shall no
longer be subject to the terms of this Agreement. Notwithstanding anything
contained in this Section 5.11(e) to the contrary, so long as the Debtor shall
(or cause the Lessee to) use, operate, maintain, inspect, service, repair,
overhaul and test the Engine and make additions or modifications to the Engine
or any Parts (and maintain and keep any Records) at a level which fully
satisfies in all respects the terms and conditions of the Lease, the Debtor
shall be deemed to have complied in all respects to the terms and conditions of
this Section 5.11(e).

        5.12   Insurance.

        (a) Engine Liability and Property Damage Insurance. Debtor represents
and warrants that it will (or will cause the Lessee to) maintain at all times,
at its own cost and expense (or at the Lessee's own cost and expense), with
insurers of recognized responsibility, (i) comprehensive aircraft and general
public liability insurance against bodily injury and property damage claims in
an amount not less than $300,000,000.00 for each single occurrence and (ii) such
other property damage insurance (exclusive of manufacturer's product liability
insurance) with respect to the Engine as is of the type and in the amounts
usually carried by companies engaged in the same or a similar business as Debtor
(or Lessee), similarly situated with Debtor (or Lessee), and owning or operating
similar aircraft and engines, and which covers risks of the kind customarily
insured against by such 



                                       34
<PAGE>   35

companies.

        (b) Insurance Against Loss or Damage to the Engine. Debtor represents
and warrants that it will (or will cause the Lessee to) maintain in effect at
all times, at its own cost and expense (or at the Lessee's own cost and
expense), with insurers of recognized responsibility, all-risk ground and flight
aircraft hull insurance covering the Engine, provided that such insurance shall
at all times be not less than the greater of (i) the full replacement value of
the Engine as such value is set forth on Exhibit C attached hereto, (ii) the
aggregate unpaid principal amount of the Note or (iii) the amount which would be
paid pursuant to Section 2.3 hereof upon the occurrence of an Event of Loss
(each such amount determined as of each anniversary of the Closing Date for the
next succeeding year throughout the term of this Agreement). Debtor shall (or
shall cause the Lessee to), at its (or the Lessee's) own cost and expense,
additionally maintain in effect with an insurer of recognized responsibility
reasonably satisfactory to Lender, hijacking (air piracy) insurance with respect
to the Engine in a face amount of not less than the greater of (i) the full
replacement value of the Engine as such value is set forth on Exhibit C attached
hereto, (ii) the aggregate unpaid principal amount of the Note or (iii) the
amount which would be paid pursuant to Section 2.3 hereof upon the occurrence of
an Event of Loss (each such amount determined as of each anniversary of the
Closing Date for the next succeeding year throughout the term of this
Agreement), which shall be in full force and effect throughout any geographical
areas at any time traversed by the Engine. Such insurance shall also include
governmental confiscation and expropriation and related insurance, if and to the
extent the same is maintained by Debtor (or Lessee, as applicable) with respect
to other aircraft owned or operated by Debtor (or Lessee, as applicable) on the
same routes as the Engine or where the custom in the United States airline
industry is to carry such insurance with respect to aircraft and engines
operated on the same routes as the Engine.

        (c) Lender as Additional Insured; Notice. Any policies of insurance
carried in accordance with this Section and any policies taken out in
substitution or replacement or any such policies (i) shall be amended to name
Lender as the additional insured as its interests may appear, (ii) with respect
to insurance carried in accordance with paragraph (b) of this Section 5.12
covering the Engine, shall provide that any amount(s) payable thereunder which
exceed $200,000.00 in the aggregate shall be paid directly to Lender as sole
loss payee and not to Lender and Debtor jointly (and, so long as no Event of
Default has occurred, such amounts shall be disbursed by Lender to Debtor or
other appropriate persons for payment of the costs actually incurred with
respect to repairs made to the Engine so as to restore it to the operating
condition required hereunder, or shall be disbursed by Lender as otherwise
required by this Agreement), and that any amount(s) of 



                                       35
<PAGE>   36

less than $200,000.00 in the aggregate shall be paid to Debtor (and such amounts
shall be applied by Debtor to pay the costs of such repairs) provided, however,
that if an Event of Default has occurred, any and all such proceeds or amounts
shall be paid directly to Lender to be applied pursuant to the applicable terms
of this Agreement, (iii) shall provide that if any insurer cancels such
insurance for any reason whatever, or any substantial change is made in any of
the coverage required hereunder, or the same is allowed to lapse for nonpayment
of premium or such insurance coverage is reduced, such cancellation, change,
lapse or reduction shall not be effective as to Lender for thirty (30) days
following receipt by Lender of written notice, and (iv) shall provide that in
respect of the interests of Lender in such policies, the insurance shall not be
invalidated by any action or inaction of Debtor or any other Person (other than
Lender). Each insurance policy and its respective cover amount(s) obtained in
accordance with the requirements set forth in paragraphs (a) and (b) of this
Section 5.12 shall (i) be primary insurance, not subject to any co-insurance
clause and shall be without right of contribution from any other insurance, and
(ii) expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured or loss payee, and shall waive any right of such insurer
to any setoff, counterclaim or other deduction, by attachment or otherwise, in
respect of Lender or Debtor. Debtor shall arrange for appropriate certification
as to the satisfaction of the requirements set forth above in this Section 5.12
to be delivered to Lender not later than the Closing Date.

        (d) Reports, etc. Upon the request of the Lender, Debtor shall furnish
to Lender a report describing in reasonable detail the insurance then carried
and maintained on the Engine and certifying that such insurance complies with
the terms hereof and such other evidence of insurance coverage that the Lender
reasonably requests. In the event Debtor shall fail to maintain insurance as
herein provided, Lender may, at its option, provide such insurance, and Debtor
shall, upon demand, reimburse Lender for the cost thereof, together with
interest at the Late Charge Rate from the date of payment through the date of
reimbursement.

        (e) Agreed Value. Anything herein to the contrary notwithstanding, at
all times while the Engine is subject to this Agreement, the insurance required
by Section 5.12 of this Agreement shall be for an amount on an "agreed value"
basis not less than the greater of (i) the full replacement value of the Engine
as such value is set forth on Exhibit C attached hereto, (ii) the aggregate
unpaid principal amount of the Note or (iii) the amount which would be paid
pursuant to Section 2.3 hereof upon the occurrence of an Event of Loss (each
such amount determined as of each anniversary of the Closing Date for the next
succeeding year throughout the term of this Agreement).

status reports regarding the Engine, which monthly status reports (and all
related documents and information) shall be reasonably satisfactory to the
Lender and shall include (i) the amount of the hours and cycles flown by the
Engine for the applicable month, (ii) notice of any repairs, overhauls,
servicing and all other maintenance procedures or services performed or required
with regard to the Engine for the applicable month as a result of any
"Airworthiness Directives" which have required the Engine to be out of service
for more than ten (10) days of said applicable month, and (iii) copies of all
reports regarding the Engine which are provided by the Lessee to the Debtor
pursuant to the terms of the Lease and copies of any reports or other
information regarding any damage to the Engine.

        5.33 Furnishing of Additional Information. Debtor agrees that it shall
furnish to Lender from time to time such information relating to the Collateral,
the Debtor or the Guarantor (or their respective Subsidiaries and/or
Affiliates), financial or otherwise, as Lender shall reasonably request;
provided, however, with regard to any additional information concerning the
Engine, the Lender shall be entitled to (i) any additional information
concerning the Engine which the Lessee is required to provide the Debtor (or the
Lender) under the terms of the Lease, and (ii) any additional information
concerning the Engine which may be in the Debtor's possession or control.

        SECTION 6. SECURITY INTEREST.

        6.1 Grant of Security Interest. As collateral security for the prompt
and complete payment and performance when due of all of the Obligations and in
order to induce Lender to enter into this Agreement and make the Loan to Debtor
in accordance with the terms hereof and to extend other credit from time to time
to Debtor, whether under this Agreement, the Note or otherwise, Debtor hereby
assigns, conveys, mortgages, pledges, hypothecates and transfers to Lender, and
hereby grants to Lender a present and continuing first priority security
interest in and lien on all of Debtor's right, title and interest in, to and
under the Collateral; but none of Debtor's (and/or any other party's of any kind
whatsoever) obligations, liabilities and/or duties of any kind whatsoever under,
or with respect to the Collateral. Notwithstanding anything to the contrary
contained herewith or otherwise, the Lender does not by virtue of this
Agreement, the Collateral Assignment or otherwise assume any obligations,
liabilities and/or duties of any kind whatsoever of the Debtor (and/or of any
other party of any kind whatsoever) under, or with respect to, the Collateral
and the Lender shall not be responsible in any way whatsoever for the
performance by the Debtor (and/or by any other party of any kind whatsoever) in
connection with, relating to, or arising under, the Collateral.



                                       41
<PAGE>   42

        The security interest granted herein shall attach to each item of
Collateral at the time Debtor has any interest of any kind whatsoever in such
Collateral without any further action of any kind whatsoever.

        6.2 Lender Appointed as Attorney-in-Fact.

        (a) Debtor hereby irrevocably constitutes and appoints Lender and any
other officer or agent thereof, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of Debtor and in the name of Debtor or in its own name, from time to
time in Lender's discretion, for the purpose of carrying out the terms of this
Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Agreement. Debtor hereby ratifies all that said attorney shall
lawfully do or cause to be done by virtue hereof. To the extent permitted by
law, this power of attorney is a power coupled with an interest and shall be
irrevocable. Without limiting the generality of the foregoing, pursuant to such
appointment, the Lender shall have authority (i) to endorse Debtor's name on any
checks, notes, drafts or any other payments or instrument relating to the
Collateral which come into the Lender's possession or control, (ii) to execute,
sign, file and record UCC financing statements, UCC amendments and other lien
recordation documents with respect to any Collateral, and (iii) to settle
insurance claims with the applicable insurer and/or to collect any insurance
proceeds from the applicable insurer in connection with any casualty occurrence
or Event of Loss.

        (b) The powers conferred on Lender hereunder are solely to protect its
interest in the Collateral and shall not impose any duty upon it to exercise any
such powers. Lender shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers and neither it nor any of
its officers, directors, employees or agents shall be responsible to Debtor for
any act or failure to act.

        SECTION 7. EVENTS OF DEFAULT.

        The term "Event of Default", wherever used herein, shall mean any of the
following events or circumstances (whatever the reason for such Event of Default
and whether it shall be voluntary or involuntary, or come about or be effected
by operation of law, or be pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation or any
administrative or governmental body):

        (a) Debtor shall fail to pay any Obligation within ten (10)

indebtedness with Lender or any parent, affiliate or subsidiary of Lender; or
either Debtor or Guarantor shall default in the performance of, or compliance
with, any term contained in any agreement or instrument evidencing or relating
to such indebtedness with Lender or any parent, affiliate or subsidiary of
Lender, if the effect of such default is to cause or permit such indebtedness to
become due prior to its stated maturity, or if any such indebtedness is not paid
at maturity; or Debtor shall otherwise be in default of any of its Obligations;
or

        (e) Debtor shall or shall attempt to remove, sell, transfer, charter,
convey, pledge, mortgage, encumber, part with possession of, assign or sublet
the Engine or any part thereof, use the Engine for an illegal purpose, or permit
the same to occur (except for the leasing of the Engine to the Lessee under the
Lease); or

        (f) either Debtor or Guarantor shall fail to perform or observe any
covenant, condition or agreement (other than those covenants, conditions or
agreements specifically referred to elsewhere in this Section 7) required to be
performed or observed by the Debtor and/or the Guarantor under this Agreement,
the Collateral Assignment, the Guaranty or any agreement, document or
certificate delivered by Debtor or the Guarantor in connection herewith, and
such failure shall continue for fifteen (15) days after written notice thereof
from Lender to Debtor and/or Guarantor; or

        (g) any representation or warranty made by Debtor in this Agreement or
any agreement, document or certificate delivered by Debtor in connection
herewith or pursuant hereto shall prove to have been incorrect, misleading, or
inaccurate in any material respect when such representation or warranty was made
or given (or, if a continuing representation or warranty, at any material 



                                       43
<PAGE>   44

time); or

        (h) any representation or warranty made by Guarantor in the Guaranty,
the Pledge Agreement or any agreement, document or certificate delivered by
Guarantor in connection therewith or pursuant hereto shall prove to have been
incorrect, misleading, or inaccurate in any material respect when such
representation or warranty was made or given (or, if a continuing representation
or warranty, at any material time); or

        (i) either Debtor or Guarantor shall generally fail to pay its debts as
they became due and such failure shall continue for ten (10) Business Days after

voluntary petition, answer or consent, seek relief under the provisions of any
other now existing or future bankruptcy or other insolvency or similar law
(other than a law which does not provide for or permit the readjustment or
alteration of Debtor's and/or the Guarantor's obligations hereunder or under the
Guaranty, as the case may be) providing for the reorganization or liquidation of
corporations, or providing for an assignment for the benefit of creditors, or
providing for an agreement, composition, extension or adjustment with their
respective creditors; or

        (j) a petition against Debtor and/or Guarantor in a proceeding under
applicable bankruptcy laws or other insolvency laws (other than any law which
does not provide for or permit any readjustment or alteration of Debtor's and/or
the Guarantor's obligations hereunder or under the Guaranty, as the case may
be), as now or hereafter in effect, shall be filed and shall not be withdrawn or
dismissed within sixty (60) days thereafter, or if, under the provisions of any
law (other than any law which does not provide for or permit the readjustment or
alteration of Debtor's and/or the Guarantor's obligations hereunder or under the
Guaranty, as the case may be) providing for reorganization or liquidation of
corporations which may apply to Debtor and/or the Guarantor, any court of
competent jurisdiction shall assume jurisdiction, custody or control of Debtor
and/or the Guarantor or of any substantial part of their respective property and
such jurisdiction, custody or control shall remain in force unrelinquished,
unstayed or unterminated for a period of sixty (60) days; or

        (k) either Debtor or Guarantor shall default in any payment,
indebtedness or other obligation to any Person (other than to the Lender or any
parent, affiliate or subsidiary of 



                                       44

Lender) regarding any loan, lease, deferred purchase price agreement,
advancement of credit or any other financing or credit arrangement or facility
of any kind whatsoever (other than those transactions, conditions, covenants,
agreements or matters specifically referred to elsewhere in this Section 7), if
the aggregate amount of such respective payment, indebtedness or obligation
regarding any such loan, lease, deferred purchase price agreement, advancement
of credit or any other financing or credit arrangement or facility of any kind
whatsoever, or if the aggregate amount of the underlying agreement, indebtedness
or obligation regarding any such default of any such loan, lease, deferred
purchase price agreement, advancement of credit or any other financing or credit
arrangement or facility of any kind whatsoever, is in excess of $250,000.00 and
such default results in the acceleration of (or the request for) any such
payment, agreement, indebtedness or obligation of any such loan, lease, deferred
purchase price agreement, advancement of credit or any other financing or credit
arrangement or facility of any kind whatsoever; or

        (l) either Debtor or Guarantor shall default in any payment,
indebtedness or other obligation to any Person (other than to the Lender or any
parent, affiliate or subsidiary of Lender or other than any payment,
indebtedness or other obligation concerning any loan, lease, deferred purchase
price agreement, advancement of credit or any other financing or credit
arrangement or facility of any kind whatsoever or any other transaction,
condition, covenant, agreement or matter specifically referred to elsewhere in
this Section 7), if the aggregate amount of such respective payment,
indebtedness or obligation, or if the aggregate amount of the underlying
agreement, indebtedness or obligation regarding any such default, is in excess
of $250,000.00 and such default results in the acceleration of (or the request
for) any such payment, agreement, indebtedness or obligation unless such default
or acceleration is subject to a bona fide dispute between the Debtor or the
Guarantor and such other party and said dispute is being diligently contested by
the Debtor or the Guarantor in good faith and by appropriate proceedings,
provided, however, any such bona fide dispute and default shall be resolved and
cured within one hundred eighty (180) days after the occurrence of such default;
or

        (m) any judgment, attachment or garnishment against Debtor and/or the

or either Debtor 



                                       45
<PAGE>   46

or Guarantor shall terminate its existence by merger, consolidation, or sale of
substantially all of its assets or otherwise (except as otherwise expressly
permitted with regard to the Guarantor in Section 5.10 of this Agreement); or

        (o) if the Guarantor shall no longer continue to control one hundred
percent (100%) of Debtor's issued and outstanding stock at all times; or

        (p) if any person or group (as defined in Rules 13d-3 and 13-5 under the
Securities Act), becomes the "beneficial owner" (as defined in Rules 13d-3 and
13d-5 under the Securities Act) of a larger number of shares of common stock of
the Guarantor than the number of shares of which CHARLES F. WILLIS, IV and
members of his family (including children, brothers and sisters) is the
beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Securities Act);
or

        (q) if either Debtor or Guarantor is a publicly held corporation, there
shall be a change in the ownership of the Debtor's or the Guarantor's, as the
case may be, stock such that the Debtor or Guarantor, as the case may be, is no
longer subject to the reporting requirements of the Securities Exchange Act of
1934, or no longer has a class of equity securities registered under Section 12
of the Securities Act of 1933; or

        (r) if a Lessee Event of Default has occurred under the Lease; or

        (s) if the Debtor ceases to be a wholly-owned Subsidiary of the
Guarantor.

        Notwithstanding Subsection (r) of this Section 7, Debtor shall have the
right, within ten (10) days after the Debtor has been given notice that a Lessee
Event of Default has occurred under the Lease, to cure, at its sole cost and
expense, any Lessee Event of Default under the Lease relating solely to the
Lessee's failure to pay any Monthly Rent, Maintenance Fees and other payments
expressly due the Debtor by the Lessee thereunder (each a "Lessee Payment
Default") by paying the Lender the applicable Monthly Rent, Maintenance Fees and
such other payments or amounts expressly due the Debtor by the Lessee under the
Lease (any such Monthly Rent, Maintenance Fees and other payments or amounts
hereinafter collectively, the "Lessee Cure Payment") within such ten (10) day
period; provided, however, that the Debtor shall only have the right to cure one
(1) Lessee Payment Default during the term of the Lease. The Debtor shall not,
as a result of exercising the right to cure any such Lessee Payment Default,
obtain any Lien on any of the Collateral (including any Monthly Rent,
Maintenance Fees or any other amounts payable under the Lease) for or on account
of any costs or expenses incurred in connection with the exercise of such right,
nor shall any claim 



                                       46
<PAGE>   47
of the Debtor against the Lessee or any other party for the repayment of such
costs or expenses impair the prior right and security interest of the Lender in
the Collateral (including any Monthly Rent, Maintenance Fees or any other
amounts payable under the Lease). Upon the receipt by the Lender of the Debtor's
payment of the applicable Lessee Cure Payment (in immediately available funds),
the Lender shall credit and apply any such payment to the applicable outstanding
Obligations, Maintenance Fees, Security Deposits and/or other amounts required
under this Agreement, as the case may be, as provided in Section 9.1, Section
10.13 or any other applicable section of this Agreement.

        SECTION 8. REMEDIES.

        8.1 Termination of Commitment. If an Event of Default specified in
subsections 7 (i) or (j) above shall occur, then, and in any such event, the
Commitment shall immediately terminate and the principal amount of the Note,
together with accrued interest thereon and all other amounts owing under or with
respect to this Agreement (including, without limitation, any prepayment premium
or fee calculated as of the date of the Event of Default which premium or fee
shall also be due and payable) shall become immediately due and payable without
any notice or other action by Lender, and if any other Event of Default shall
occur and be continuing, then, and in any such event, Lender may (a) terminate
forthwith the Commitment and/or (b) declare the Note to be forthwith due and
payable, whereupon the remaining principal amount of the Note, together with
accrued interest thereon and all other amounts owing under or with respect to
this Agreement (including, without limitation, any prepayment premium or fee
calculated as of the date of the Event of Default which premium or fee shall
also be due and payable), shall become immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived, anything contained herein or in the Note to the
contrary notwithstanding. During the continuance of any Event of Default
hereunder, Lender shall have the right to pursue and enforce any of its rights
and remedies under Section 8, Subsections 8.2 through 8.4, inclusive, hereof.

        8.2 Additional Remedies. Upon the occurrence of any Event of Default,
Lender may, at its sole option and discretion, in addition to any other rights
or remedies granted to it under this Agreement, at law or in equity or under any
other instrument or agreement securing, evidencing or relating to the
Obligations, exercise one or more of the following remedies with respect to any
or all of the Collateral: (a) cause Debtor to, at Debtor's expense, promptly
return such Collateral (or any portion thereof requested by Lender) to such
location as Lender may from time to time reasonably designate, or Lender, at its
option, may enter upon the premises where the Collateral (or any portion thereof


                                       47
<PAGE>   48
requested by Lender) is located and take immediate possession of and remove the
same by self-help (to the extent permitted by law), or summary proceedings or
otherwise all without liability to Lender for or by reason of damage to property
or such entry or taking possession; provided, however, that the Lender shall not
remove any Collateral in the possession of the Lessee under the Lease so long as
no default or event of default exists under the Lease; (b) sell any or all of
the Collateral at public or private sale or otherwise dispose of, hold, use,
operate, lease to others or keep idle the Collateral (or any portion thereof),
all as Lender in its sole discretion may determine and all free and clear of any
rights of Debtor; (c) remedy such default, including making repairs or
modifications to any Collateral, for the account of and the expense of Debtor
and Debtor agrees to reimburse Lender for all of Lender's reasonable costs and
expenses; (d) apply any security deposit or other cash collateral or sale or
remarketing proceeds of any Collateral at any time as it sees fit to reduce any
amounts due to Lender (other than any payments or amounts held in the Account
which are solely Maintenance Fees or Security Deposits which payments or amounts
shall be disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13
of this Agreement); and (e) exercise any other right or remedy which may be
available to it under applicable law and the UCC or proceed by appropriate court
action to enforce the terms hereof or to recover damages for the breach hereof.
In addition to the foregoing, Debtor shall continue to be liable for all
indemnities under this Agreement and the Note and for all legal fees and other
costs and expenses resulting from any Event of Default or the exercise of
Lender's remedies. Without limiting the generality of the foregoing, Lender
shall (i) have the right upon any public sale or sales, and, to the extent
permitted by law, upon any such private sale or sales to purchase the whole or
any part of the Collateral so sold, free of any right or equity of redemption in
Debtor, which right or equity is hereby expressly released, and/or (ii) apply
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale (after deducting all reasonable costs and expenses of every
kind incurred therein or incidental to the care, safekeeping or otherwise of any
or all of the Collateral or in any way relating to the rights of Lender
hereunder, including attorney's fees and legal expenses) to the payment in whole
or in part of the Obligations, in such order as Lender may elect and only after
so applying such net proceeds and after the payment by Lender of any other
amount required by any provision of law (including Section 9-504(1)(c) of the
UCC), need Lender account for the surplus, if any, to Debtor. To the extent
permitted by applicable law, Debtor waives all claims, damages, and demands
against Lender arising out of the repossession, retention or sale of the
Collateral. Debtor agrees that Lender need not give more than ten (10) days'
notice (which notification shall be deemed given when mailed, postage prepaid,
addressed to Debtor at its address set forth in Section 10.2. hereof or
delivered by overnight delivery service to the Debtor at such 



                                       48
<PAGE>   49

address) of the time and place of any public sale or of the time after which a
private sale may take place and that such notice is reasonable notification of
such matters. Debtor shall be liable for any deficiency if the proceeds of any
sale or disposition of the Collateral are insufficient to pay all amounts to
which Lender is entitled.

        8.3 Costs of Collection. Debtor shall be liable for, and also agrees to
pay, all costs, charges and expenses of Lender, including reasonable attorneys'
fees and disbursements, incurred by or on behalf of Lender with respect to (i)
any Event of Default, (ii) the collection of any of the Obligations, (iii) the



                                       49
<PAGE>   50

enforcement of any of its respective rights under this Agreement, at law or in
equity or otherwise and/or (iv) the exercise of any of Lender's rights or
remedies under this Agreement, at law or in equity or otherwise.

        8.4 Waivers. Without limiting the generality of any other terms of this
Agreement, Debtor hereby waives presentment, demand, protest or any notice,
except as expressly provided herein, (to the extent permitted by applicable law)
of any kind in connection with this Agreement or any Collateral.

        SECTION 9. ACCOUNT

        9.1 Account.

        (a) All proceeds of checks, notes, cash and other proceeds of the Lease
Receivables as well as all proceeds from the sale of the Engine, any securities
(other than securities issued by Debtor) and any other Collateral and other cash
receipts of every kind and nature (other than the proceeds of any other
borrowing or amount expressly permitted by this Agreement) shall be collected
into any account required by the Lender in its sole discretion (the "Account")
commencing on the date of this Agreement and at all times hereafter pursuant to
the terms of this Section 9.1. The Lender shall maintain the Account at all
times until the Loan and any and all other Obligations of the Debtor due or
owing to the Lender under this Agreement, the Note, the Collateral Assignment or
any agreement, instrument or document evidencing any other Obligations have been
paid in full. Simultaneously with the Debtor's execution of this Agreement, the
Debtor shall direct the Lessee to make all payments under the Lease directly to
the Lender and into the Account. The Debtor shall hold in trust for Lender and
immediately remit to Lender by depositing the same into the Account all checks,
notes, cash and other proceeds of the Lease Receivables as well as all proceeds
from the sale of the Engine, any securities (other than securities issued by
Debtor) and any other Collateral and other cash receipts of every kind and
nature (other than the proceeds of other borrowing or amount expressly permitted
by this Agreement). The Debtor agrees that all payments or amounts received in
the Account will be the sole and exclusive property of Lender. The Lender shall,
on the second (2nd) Business Day after which any payment or amount is received
into the Account, and on a provisional basis until the final receipt of good
funds, (i) credit and apply all payments or amounts held in the Account which
are Monthly Rent to the applicable monthly principal and interest installment
due under the Note and any other outstanding amounts due or payable under the
Note and this Agreement, (ii) so long as no Lessee Event of Default exists under
the Lease, hold all payments or amounts held in the Account which are solely
Maintenance Fees and/or Security Deposits pursuant to the terms of this Section
9 and/or Section 10.13 of this Agreement, and (iii) so long as no Event of
Default exists under this Agreement, the Note, the Collateral Assignment or any
agreement, instrument 



                                       50
<PAGE>   51

or document evidencing any other Obligations, disburse the remaining amounts
held in the Account (after application to the payments or amounts due or payable
under the Note and this Agreement as provided in subclause (i) above) which are
not Maintenance Fees or Security Deposits expressly due or payable under the
Lease (or are not accrued interest on any Maintenance Fees or Security Deposits)
to the Debtor by wire transfer to Wells Fargo Bank, San Francisco, CA 94163, ABA
No. 121 000 248, Account No. 4518-101423 or to such other address or bank
account requested by the Debtor pursuant to the notice provisions of Section
10.2 of this Agreement. Upon the occurrence of an Event of Default under this
Agreement, the Note, the Collateral Assignment or any agreement, instrument or
document evidencing any other Obligations, the Lender shall, on the second (2nd)
Business Day after which any payment or amount is received into the Account
(other than any payments or amounts held in the Account which are solely
Maintenance Fees or Security Deposits which payments or amounts shall be
disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13 hereof),
and on a provisional basis until the final receipt of good funds, credit and
apply all such payments or amounts (including, without limitation, any accrued
interest on any amounts contained in the Account) first, to any amounts due or
outstanding under the Note (including, without limitation, all principal,
accrued interest or any prepayment premium or fee calculated as of the date of
the Event of Default which premium or fee shall also be due and payable),
second, the remainder of any such payments or amounts, if any (or in the event
there are no amounts due or outstanding under the Note, all such payments or
amounts shall be applied), to any other amounts due or payable under this
Agreement, the Collateral Assignment, or any amounts due or outstanding under
any agreement, instrument or document evidencing any other Obligations, and
third, the remainder of any such payments or amounts, if any, to a cash
collateral account under the sole dominion and control of Lender until such
Event of Default is cured by Debtor pursuant to the applicable terms of this
Agreement or any other applicable agreement or waived by Lender in its sole
discretion. Any provisional credit hereunder is subject to reversal if the final
collection of a payment is not received by the Lender within five (5) Business
Days following the initial receipt of such payment and will thereafter be
credited when such payment is actually received in good funds. The Debtor agrees
that it shall promptly pay to the Lender $85.00 per month for the Lender's
administration of the Account, together with, if any, all other reasonable fees
charged, and all reasonable expenses incurred, by the Lender in connection with
the administration of the Account. The Lender shall send the Debtor monthly
invoices regarding the $85.00 monthly payment and any other reasonable fees or
expenses charged or incurred in connection with the Lender's administration of
the Account. Without in any way whatsoever limiting the generality of the terms
of this Agreement, the Note, the Collateral Assignment or any other terms and
conditions of any other agreement, instrument 



                                       51
<PAGE>   52

or document evidencing any other Obligations, Debtor hereby irrevocably appoints
Lender its attorney-in-fact to endorse Debtor's name on any checks, notes,
drafts or any other payments or instruments relating to such items (and/or any
Collateral) which come into the Lender's possession or control pursuant to the
Account and to take any other action of any kind whatsoever that the Lender
deems necessary or desirable in its sole discretion regarding the same and/or
the Account, including, without limitation, inserting missing dates on checks,
notes, drafts or any other payments or instruments and/or rejecting and/or
returning checks, notes, drafts or any other payments or instruments, without
being liable in any way whatsoever for wrongful dishonor or any other thing or
matter of any kind whatsoever. To the extent appropriate or permissible under
the applicable law, such power is coupled with an interest and shall be
irrevocable. In addition, such power shall terminate only upon the Debtor's
payment and/or performance, as the case may be, in full of all of the
indebtedness and/or obligations of any kind whatsoever owing or due to the
Lender by the Debtor. Neither the Lender nor its counsel will be liable for any
acts or omissions nor error of judgment or mistake of fact or law in connection
with the exercise and/or enforcement of its rights under this Section 9. Nothing
contained in this Agreement, the Collateral Assignment or any other agreement,
instrument or document evidencing any other Obligations or otherwise or any acts
or omissions of the Lender or its counsel shall be deemed, or construed, in any
way whatsoever as the Lender being in control of the management and/or affairs
of the Debtor (other than to exercise the rights granted to the Lender under
this Agreement, the Collateral Assignment or any other agreement, instrument or
document evidencing any other Obligations to, among other things, protect its
interest in the Collateral). The Debtor further agrees that the terms of this
Section 9 are in addition to, and do not in any way whatsoever limit, the terms
of this Agreement or any related cash management or lockbox agreements or
documents executed and/or delivered in connection herewith. However, in the
event of a conflict between the terms and provisions of this Section 9 and any
related cash management or lockbox agreements or documents executed and/or
delivered in connection herewith, the applicable terms and provisions of this
Section 9 shall control for all purposes. Notwithstanding anything to the
contrary contained in this Section 9 or otherwise, all payments, funds or
amounts received into the Account (including, without limitation, all Monthly
Rent, Maintenance Fees and Security Deposits) may also be commingled with the
Lender's other funds and no trust relationship of any kind whatsoever shall
exist between the Lender and the Debtor as to any such payments, funds or
amounts so deposited. No interest shall be payable with regard to any payments,
funds or amounts deposited into the Account except as otherwise expressly
provided in Section 9.1(b) hereof.

        (b) The amount of all existing Maintenance Fees and Security Deposits
only held in the Account shall bear interest at a variable rate equal to the
Libor Rate for each Interest Period. 



                                       52
<PAGE>   53

Any interest accrued on the Maintenance Fees and/or the Security Deposits
pursuant to the immediately preceding sentence for any Interest Period shall be
credited into the Account on the first day of each calendar month immediately
following said Interest Period or on the first Business Day of such calendar
month (said first day or first Business Day of each calendar month hereinafter
the "Interest Credit Day") so long as any such Maintenance Fees and/or Security
Deposits are required to be maintained in the Account pursuant to the terms of
this Section 9. The Maintenance Fees and/or the Security Deposits (including,
without limitation, any accrued interest thereon), shall not be released and/or
disbursed to the Debtor (or any other party) until any and all obligations
outstanding under the Note, the Collateral Assignment and this Agreement (other
than any obligations relating solely to any other agreement, instrument or
document between the Debtor and the Lender) have been fully paid and/or
performed, as the case may be, except as otherwise expressly provided in Section
9.1(c) hereof, provided, however, that upon the occurrence of any Event of
Default under this Agreement, the Note, the Collateral Assignment or any
agreement, instrument or document evidencing any other Obligations, the
Maintenance Fees and the Security Deposits (including, without limitation, any
accrued interest thereon), shall not be released and/or disbursed to the Debtor
until any and all Obligations outstanding by the Debtor under this Agreement,
the Note, the Collateral Assignment or any other agreement, instrument or
document between the Debtor and the Lender have been fully paid and/or
performed, as the case may be, except as otherwise expressly provided in Section
9.1(c) hereof; provided further, however, that nothing contained in the
foregoing proviso shall be deemed to limit, impair or adversely affect in any
way whatsoever the Lender's rights under this Agreement, the Collateral
Assignment or any other agreements, documents or instruments to set off, debit
or apply any Maintenance Fees, Security Deposits or any other amounts as
provided in Section 9.1(c) or Section 10.13 of this Agreement or any other
applicable section of this Agreement.

        (c) So long as no Lessee Event of Default exists under the Lease, upon
three (3) Business Days prior written notice by the Debtor to the Lender for the
release of any Maintenance Fees which are being held in the Account, and receipt
by the Lender from the Debtor of such documents (including, without limitation,
such documents required to be supplied by the Lessee under the Lease or the
General Terms Agreement relating to any such amounts) as the Lender shall
reasonably request to document the Lessee's right to such Maintenance Fees, the
Lender shall disburse directly to the Lessee (or the applicable vendor, supplier
or maintenance company performing the applicable maintenance work or to the
Debtor if the Debtor has already paid for any such maintenance work) on behalf
of the Debtor the amount of any Maintenance Fees which the Lender expressly
agrees shall be released from the Account (which approval or agreement shall be
in the reasonable determination of the Lender). Upon and after 



                                       53
<PAGE>   54

the occurrence of a Lessee Event of Default under the Lease (but without
limiting any rights of the Lender to debit, apply or set off any amounts in the
Account which are not Maintenance Fees or Security Deposits, including, without
limitation, all Monthly Rent and accrued interest in the Account), the Lender
shall have the absolute right to immediately debit the Account for any
Maintenance Fees and Security Deposits (and the amounts in the Account relating
to Maintenance Fees and Security Deposits shall be immediately released
accordingly), and apply the proceeds thereof first, to any amounts due or
outstanding under the Note (including, without limitation, all principal,
accrued interest or any prepayment premium or fee calculated as of the date of
the Event of Default which premium or fee shall also be due and payable),
second, the remainder of any such amounts, if any, to any other amounts due or
payable under this Agreement, the Collateral Assignment, or any amounts due or
outstanding under any agreement, instrument or document evidencing any other
Obligations, and third, the remainder of any such amounts, if any, to a cash
collateral account under the sole dominion and control of Lender until such
Event of Default is cured by Debtor pursuant to the applicable terms of this
Agreement or any other applicable agreement or waived by Lender in its sole
discretion; provided, however, that in the event the Debtor exercises its right
to cure one (1) Lessee Payment Default and pays the Lender the applicable Lessee
Cure Payment pursuant to the terms of the last paragraph of Section 7 of this
Agreement, upon the receipt by the Lender of the Debtor's payment of the
applicable Lessee Cure Payment (in immediately available funds), the Lender
shall credit any amounts into the Account which the Lender has set off or
debited against Maintenance Fees or Security Deposits only with a corresponding
amount from the Debtor's payment of the Lessee Cure Payment, and effective as of
any such credit such amounts shall be deemed Maintenance Fees and/or Security
Deposits, as the case may be, and, if applicable, the Lender shall also credit
or apply any remaining amounts of such payment as provided in Section 9.1(a),
Section 9.1(b) or Section 10.13 of this Agreement or any other applicable
section of this Agreement.

        SECTION 10. MISCELLANEOUS.

        10.1 No Waiver; Cumulative Remedies. No failure or delay on the part of
Lender in exercising any right, power or privilege hereunder or under the Note
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
No right or remedy in this Agreement is intended to be exclusive but each shall
be cumulative and in addition any other remedy referred to herein or otherwise
available to Lender at law or in equity; and the exercise by Lender of any one
or more of such remedies shall not preclude the simultaneous or later exercise
by Lender of any or all such other remedies. No express or implied waiver by
Lender of an Event of Default shall in any way be, or be construed to be, a
waiver of any future or 



                                       54
<PAGE>   55

subsequent Event of Default. After the occurrence of any Event of Default, the
acceptance by Lender of any installment of principal and interest or of any
other sum owing hereunder or under the Note shall not constitute a waiver of
such Event of Default, regardless of Lender's knowledge or lack of knowledge
thereof at the time of acceptance of any such payment, and shall not constitute
a reinstatement of this Agreement and/or the Note if Lender has sent Debtor a
notice of default, unless Lender shall have agreed in writing to reinstate this
Agreement and/or the Note and waive the Event of Default. To the extent
permitted by law, Debtor waives any rights now or hereafter conferred by statute
or otherwise which limit or modify any of Lender's rights or remedies under this
Agreement and/or the Note.

        10.2 Notices. All notices, requests and demands to or upon any party
hereto shall be deemed to have been duly given or made when received by
overnight delivery service to the address indicated below or when deposited in
the United States mail, return receipt requested first class postage prepaid,
addressed to such party as follows, or to such other address as may be hereafter
designated in writing by such party to the other party hereto:

taxes in connection with the recording of this Agreement or any other document
or instrument required hereby; and (iii) all costs and expenses of Lender in

taxes (other than any corporate income, capital, franchise or similar taxes
payable by Lender with respect to the payments made to Lender hereunder or



                                       55

thereunder) and all license, filing, and registration fees and assessments and
other charges, if any, which may be payable or determined to be payable in

        (b) Debtor hereby further agrees, whether or not the transactions

and hereby agrees to indemnify, protect, save, defend and keep harmless Lender

limitation, claims involving or alleging product liability or strict or absolute
liability in tort), actions, suits, demands, costs, expenses and disbursements
(including, without limitation, legal fees and expenses) of any kind and nature
whatsoever (the foregoing being collectively referred to as the "Indemnified
Liabilities") which may be imposed on, incurred by or asserted against any
Indemnified Parties, whether or not any such Indemnified Parties shall also be
indemnified as to any such Indemnified Liabilities by any other Person, in any
way relating to or arising out of this Agreement or any documents contemplated
hereby, or the performance or enforcement of any of the terms hereof or thereof,
or in any way relating to or arising out of the manufacture, inspection,
construction, purchase, acceptance, rejection, ownership, titling or re-titling,
delivery, lease, sublease, possession, use, operation, maintenance, condition,
registration or re-registration, sale, return, removal, repossession, storage or
other disposition of the Engine or any part thereof or any accident in
connection therewith (including, without limitation, latent and other defects,
whether or not discoverable, and any Indemnified Liabilities for patent,
trademark or copyright infringement, provided, however, that Debtor shall have
no obligations thereunder with respect to Indemnified Liabilities arising from
the gross negligence or willful misconduct of Lender.

        (c) If Debtor fails to perform or comply with any of its agreements
contained herein and Lender shall itself perform or comply, or otherwise cause
performance or compliance, with such agreement, the reasonable expenses of
Lender incurred in connection with such performance of compliance, together with
interest thereon at the rate provided for in the Note shall be payable by Debtor
to Lender on demand and until such payment shall constitute Obligations secured
hereby.

        10.4 Entire Agreement. This Agreement, together with the Note, the

delivered in connection therewith, as applicable, constitutes the entire

        10.6 Amendments. Neither this Agreement, nor any terms hereof, may be

writing signed by the party against which enforcement of a change, waiver,
discharge or termination is sought.

        10.7 Counterparts. This Agreement may be executed by the parties hereto
on any number of separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together
constitute but one and the same instrument.

        10.8 Headings. The headings of the Sections and paragraphs are for

        10.9 Successors or Assigns. This Agreement shall be binding upon and
inure to the benefit of Debtor and Lender and their respective heirs, executors,

        10.10 Authorization. Lender, its agents, representatives and employees

        10.12 Additional Waivers. Without limiting the generality of any other

Agreement, the Note or any Obligations, or any payment hereunder or thereunder,
may be extended, modified or subordinated (by forbearance or otherwise), or the
terms hereof or thereof, as the case may be, may be modified or amended with the
Debtor, from time to time, without in any way affecting in any way the
obligations or the liability of the Debtor or any endorser or guarantor of
Debtor or otherwise. The Debtor hereby further consents and agrees that the
Lender or any other party may release or surrender, exchange or substitute any

thereof) now held or which may hereafter be held as security for this Agreement,
the payment of the Note and/or any Obligations, or may add any property as
security, or may release any party liable hereunder or under any applicable loan
documents or otherwise, all without releasing in any way the obligations or the
liability of the Debtor or any endorser or guarantor of Debtor or otherwise. The
Debtor hereby further expressly waives any right to require the Lender or any
other party to marshal any property or other collateral security of any kind
whatsoever (or any portion thereof) now held or which may hereafter be held as
security for this Agreement, the payment of the Note and/or any Obligations or
otherwise to compel the Lender or any other party to seek recourse against or
satisfaction of the indebtedness owed to it from one source before seeking
recourse or satisfaction from another source.

        10.13 Right of Set Off. Upon the occurrence of an Event of Default under
this Agreement, the Lender is hereby authorized at any time and from time to
time without notice to the Debtor or any other party (any such notice being
expressly waived by the Debtor), to set off and apply any and all deposits
(general or special, time or demand, provisional or final) of any kind
whatsoever at any time held, including, without limitation, any amounts or
proceeds (including, without limitation, any accrued interest) contained in the
Account (other than any Maintenance Fees or Security Deposits as expressly
provided below), and other indebtedness at any time owing by the Lender to or
for the credit or the account of the Debtor against any and all of the



                                       58
<PAGE>   59

obligations of the Debtor now or hereafter existing under this Agreement, the
Note, the Collateral Assignment or any agreement, document or instrument
evidencing any other Obligations, irrespective of whether or not the Lender
shall have made any demand under this Agreement, the Note, the Collateral
Assignment or any agreement, document or instrument evidencing any other
Obligations, and although such obligations may be unmatured; provided, however,
that the Lender shall not be authorized to set off any amounts in the Account
which are solely Maintenance Fees and/or Security Deposits without notice to the
Debtor or any other party until after the occurrence a Lessee Event of Default
under the Lease, and upon the occurrence of any such Lessee Event of Default,
the Lender shall have the right to set off and apply any and all Maintenance
Fees and/or Security Deposits without notice to the Debtor as provided in this
Section 10.13; provided further, however, that in the event the Debtor exercises
its right to cure one (1) Lessee Payment Default and pays the Lender the Lessee
Cure Payment pursuant to the terms of the last paragraph of Section 7 of this
Agreement, upon the receipt by the Lender of the Debtor's payment 
of the applicable Lessee Cure Payment (in immediately available funds), the
Lender shall credit any amounts into the Account which the Lender has set off or
debited against Maintenance Fees or Security Deposits only with a corresponding
amount from the Debtor's payment of the Lessee Cure Payment, and effective as of
any such credit such amounts shall be deemed Maintenance Fees and/or Security
Deposits, as the case may be, and, if applicable, the Lender shall also credit
or apply any remaining amounts of such payment as provided in this Section 10.13
or in Section 9.1(a) or Section 9.1(b) of this Agreement or any other applicable
section of this Agreement. The Lender agrees promptly to notify the Debtor after
any such set off and application, provided that the failure to give such notice
shall not affect the validity of such setoff and application. The rights of the
Lender under this Section 10.13 are in addition to any other rights and remedies
of any kind whatsoever (including, without limitation, other rights of setoff)
which the Lender may have.

        10.14 Primary Obligations. Notwithstanding anything to the contrary
contained herein or otherwise, the Debtor shall be, and remain, primarily and
fully liable and obligated for any and all Obligations and the performance of
all terms and conditions hereunder notwithstanding the Lease and the Lessee's
obligations thereunder.

        10.15 Assignment By Lender. Lender, may at any time, without notice to
Debtor, mortgage, grant a security interest in or otherwise transfer, sell or
assign all or any part of its interest in this Agreement, the Note, the

due or to become due hereunder or under the Note, this Agreement, the Guaranty
or any other documents or agreements or under the Obligations and Debtor shall

                                       59
<PAGE>   60

obligations under this Agreement, the Note and the Obligations for the benefit
of such assignee, lender, creditor, mortgagee, transferee or Person of Lender
except that the interest of any such assignee, lender, creditor, mortgagee,
transferee or Person of Lender shall be subject to Debtor's rights of use and
possession, so long as no Default or Event of Default has occurred and is
continuing hereunder; provided, however, that any transfer, sale or assignment
of all or any part of the Lender's interest in this Agreement, the Note, the
Collateral Assignment, the Guaranty, the Pledge Agreement, the Pledged Stock,
the Stock Powers, the Obligations, or the Engine or any payments or other sums
due or to become due hereunder or under the Note, this Agreement, the Guaranty
or any other documents or agreements or under the Obligations to any Competitor
of the Debtor or the Guarantor or to any Designated Lender of a Competitor of
the Debtor or the Guarantor shall be subject to the prior written consent of the
Debtor and the Guarantor, which consent by the Debtor and the Guarantor shall
not be unreasonably withheld or conditioned and shall be given or denied by the
Debtor and the Guarantor within ten (10) Business Days after receipt by the
Debtor and the Guarantor of any request by the Lender for such consent, and in
the event that the Debtor or the Guarantor do not object in writing to any such
request by the Lender within in such ten (10) Business Day period any such
failure to so object shall be deemed (without any further action of any kind
whatsoever) an absolute waiver of the Debtor's and the Guarantor's rights to
object to any such assignment, sale or transfer; provided further, however, that
no consent of any kind of the Debtor or the Guarantor shall be required for any
merger or consolidation between the Lender or any parent, affiliate or
subsidiary of the Lender and any Competitor of the Debtor or the Guarantor or
any Designated Lender of a Competitor of the Debtor or the Guarantor (or any
parent, affiliate or subsidiary of any such Competitor or Designated Lender).
Debtor agrees that the rights hereunder of any such assignee, lender, creditor,
mortgagee, transferee or Person of Lender shall not be subject to any defense,
setoff, recoupment, abatement, reduction, claim or counterclaim (collectively
the "Defenses") that Debtor has or may at any time have against Lender and/or
its agents, employees, officers, directors, shareholders, subsidiaries,
affiliates, successors, and assigns for any reason whatsoever; and Debtor hereby
waives any right to assert at any time any of the foregoing Defenses against any
such assignee, lender, creditor, mortgagee, transferee or Person of Lender.
Debtor further agrees, if so directed in writing, to, among other things, pay
all sums due or to become due hereunder or under the Note and/or the Obligations
directly to the assignee, lender, creditor, mortgagee, transferee or Person of
Lender or any other party designated in writing by Lender or any such assignee,
lender, creditor, mortgagee, transferee or Person of Lender. Upon the written
request of Lender or any assignee, lender, creditor, mortgagee, transferee or
Person of Lender, Debtor also agrees (i) to promptly execute and deliver to
Lender or to such assignee, lender, creditor, mortgagee, transferee or Person of
Lender an acknowledgment of assignment in form and substance satisfactory to 



                                       60
<PAGE>   61

the requesting party which, among other things, reaffirms the basic terms and
conditions of this Agreement, the Note and/or the Obligations, and (ii) to
comply with the reasonable demands of any such assignee, lender, creditor,
mortgagee, transferee or Person of Lender in order to perfect any such
assignment or transfer, at Lender's sole expense.

        10.16 Jurisdiction. Debtor hereby irrevocably consents and agrees that
any legal action, suit, or proceeding arising out of or in any way in connection
with this Agreement may be instituted or brought in the courts of the State of
Rhode Island or the United States Courts for the District of Rhode Island, as
Lender may elect or in any other state or Federal Court as Lender shall deem
appropriate, and by execution and delivery of this Agreement, Debtor hereby
irrevocably accepts and submits to, for itself and in respect of its property,

mail, postage prepaid, to Debtor at the address set forth in Section 10.2
hereof, such method of service to constitute, in every respect, sufficient and
effective service of process in any such legal action or proceeding. Nothing in
this Agreement shall affect the right to service of process in any other manner
permitted by law or limit the right of Lender to bring actions, suits or
proceedings in the courts of any other jurisdiction. Debtor further agrees that
final judgment against it in any such legal action, suit or proceeding shall be
conclusive and may be enforced in any other jurisdiction, within or outside the
United States of America, by suit on the judgment, a certified or exemplified
copy of which shall be conclusive evidence of the fact and the amount of the
liability.

        10.17 Jury Waiver. THE DEBTOR HEREBY KNOWINGLY AND FREELY WAIVES ITS
RIGHTS TO A JURY TRIAL IN ANY ACTION, SUIT OR PROCEEDING RELATING TO, ARISING

        Re: Engine Loan and Security Agreement

Gentlemen:

        We have acted as general counsel for T-12 Inc., a California corporation
("Debtor"), and Willis Lease Finance Corporation, a California Corporation
("Guarantor") in connection with the execution of the Engine Loan and Security
Agreement of even date (the "Agreement"), between Debtor and Fleet Capital
Corporation ("Lender") and the related transactions contemplated thereby. Terms
not otherwise defined herein shall have the defined meanings set forth in the
Agreement.

        We are familiar with the Debtor and the Guarantor, their respective
affairs, and their respective charter, by-laws, and corporate records. We have
examined originals or copies, certified or otherwise identified to our
satisfaction, or such records, instruments, decisions, certificates, and
documents, have made such inquiries as to questions of fact of officers and
representatives of Debtor and the Guarantor and have made such examinations of
laws, rules, regulations, orders, decrees, writs, judgments, awards,
injunctions, and the like, as are necessary and appropriate for purposes of
giving the opinions hereinafter expressed.

        Based upon the foregoing, it is our opinion:

        1.     Debtor is a corporation duly organized, validly existing and in
               good standing under the laws of the State of California, has the
               necessary authority and power to own the Engine and its other
               assets and to transact the business in which it is engaged, and
               is duly qualified to do business in each jurisdiction in which
               the conduct of its business or the ownership or operation of its
               assets requires such qualification.

        2.     Debtor is a citizen of the United States within the 


                                       1
<PAGE>   68

               meaning of Subtitle VII of Title 49 of the United States Code, as
               amended and recodified.

        3.     Debtor has full power, authority and legal right to execute and
               deliver the Agreement, the Note, the Collateral Assignment and
               all other instruments to be executed and delivered pursuant to
               the Agreement, to perform its obligations thereunder, to borrow
               thereunder and to grant the security interest created by the
               Agreement and the Collateral Assignment.

        4.     No consent of any other party (including any partners,
               stockholders, trustees or holders of indebtedness), and no
               consent, license, approval or authorization of, exemption by, or
               registration or declaration with, any governmental body,
               authority, bureau or agency is required in connection with the
               execution, delivery or performance by Debtor of the Agreement,
               the Note, the Collateral Assignment and any other instruments to
               be executed and delivered pursuant to the Agreement, or the
               validity or enforceability of the Agreement, the Note, the
               Collateral Assignment and any other instruments to be executed
               and delivered pursuant to the Agreement, except recordation of
               the Agreement with the FAA, which shall have been duly effected
               as of the Closing Date.

        5.     The execution, delivery and performance by Debtor of each of the
               Agreement, the Note, the Collateral Assignment and any other
               instruments to be executed and delivered pursuant to the
               Agreement does not and shall not violate any provision of any
               applicable law or regulation or of any judgment, award, order,
               writ or decree of any court or governmental instrumentality, will
               not violate any provision of the charter or by-laws of Debtor and
               will not violate any provision of or cause a default under any
               mortgage, indenture, contract, agreement or other undertaking to
               which Debtor is a party or which purports to be binding upon
               Debtor or upon any of its assets, and will not result in the
               creation or imposition of any Lien on any of the assets of Debtor
               other than the security interest intended to be created by the
               Agreement and the Collateral Assignment.

        6.     The Agreement, the Collateral Assignment and any other
               instruments to be executed and delivered pursuant to the
               Agreement have been duly 


                                       2

<PAGE>   69

               authorized, executed and delivered by Debtor and constitutes
               legal, valid and binding obligations of Debtor enforceable in
               accordance with their respective terms. The Note and the Schedule
               have been duly authorized, executed and delivered by Debtor and
               constitutes legal, valid and binding obligations of Debtor
               enforceable in accordance with their respective terms.

        7.     To the best of Debtor's actual knowledge, there is no action,
               suit, investigation or proceeding (whether or not purportedly on
               behalf of Debtor) pending or threatened against or affecting
               Debtor or any of its assets (a) which involves the Engine or any
               of the transactions contemplated by the Agreement, the Note, the
               Collateral Assignment and any other instruments to be executed
               and delivered pursuant to the Agreement; or (b) which, if
               adversely determined, could have an adverse effect upon the
               transactions contemplated by the Agreement, the Note, the
               Collateral Assignment and any other instruments to be executed
               and delivered pursuant to the Agreement or a material adverse
               effect on the business, operations or financial condition of
               Debtor.

        8.     On the Closing Date Debtor shall have good and marketable title
               to the Engine subject to no Liens except the security interest in
               favor of Lender and the interest of the Lessee in the Engine
               pursuant to the Lease.

        9.     On the Closing Date Lender shall have a legal, valid and
               continuing first and only priority security interest in the
               Collateral, free and clear of all other Liens except for the
               interest of the Lessee in the Engine pursuant to the Lease, and
               all filings, recordings or other actions necessary or desirable
               in order to establish, protect and perfect such security interest
               in favor of Lender as a perfected first and only priority
               security interest in the Collateral will have been duly effected,
               and all taxes, fees and other charges in connection therewith
               shall have been duly paid.

        10.    Debtor is not in default, and no event or condition exists which
               after the giving of notice or lapse of time or both would
               constitute an event of default, under any mortgage, indenture,
               contract, agreement, judgment or other undertaking to which
               Debtor is a party or which purports to be 


                                       3

<PAGE>   70

               binding upon Debtor or upon any of its assets, except for any
               such default, event or condition which, individually or in the
               aggregate, would not affect Debtor's ability to perform its
               obligations under the Agreement or any such mortgage, indenture,
               contract, agreement, judgment or other undertaking.

        11.    Guarantor is a corporation duly organized, validly existing and
               in good standing under the laws of the State of California, has
               the necessary authority and power to own and operate its assets
               and to transact the business in which it is engaged, and is duly
               qualified to do business in each jurisdiction where its failure
               to do so would adversely affect its business, operations or
               financial condition or its ability to perform under the Guaranty,
               the Pledge Agreement, the Stock Powers and all other instruments
               to be executed and delivered pursuant thereto and to perform its
               obligations thereunder.

        12.    Guarantor has full power, authority and legal right to execute

               and all other instruments to be executed and delivered pursuant
               thereto and to perform its obligations thereunder.

        13.    No consent of any other party (including any partners,
               stockholders, trustees or holders of indebtedness), and no
               consent, license, approval or authorization of, exemption by, or
               registration or declaration with, any governmental body,
               authority, bureau or agency is required in connection with the
               execution, delivery or performance by Guarantor of the Guaranty,
               the Pledge Agreement, the Stock Powers and all other instruments
               to be executed and delivered pursuant thereto, or the validity or
               enforceability of the Guaranty, the Pledge Agreement, the Stock
               Powers and all other instruments to be executed and delivered
               pursuant thereto.

        14.    The execution, delivery and performance by Guarantor of each of
               the Guaranty, the Pledge Agreement, the Stock Powers and all
               other instruments to be executed and delivered pursuant thereto
               does not and shall not violate any provision of any applicable
               law or regulation or of any judgment, award, order, writ or
               decree of any court or governmental instrumentality, will not
               violate any provision of the charter or 


                                       4

               by-laws of Guarantor and will not violate any provision of or
               cause a default under any mortgage, indenture, contract,
               agreement or other undertaking to which Guarantor is a party or
               which purports to be binding upon Guarantor or upon any of its
               assets, and will not result in the creation or imposition of any
               Lien on any of the assets of Guarantor other than the security
               interest intended to be created by the Pledge Agreement.

        15.    The Guaranty, the Pledge Agreement, the Stock Powers and all
               other instruments to be executed and delivered pursuant thereto
               have been duly authorized, executed and delivered by Guarantor
               and constitute legal, valid and binding obligations of Guarantor
               enforceable in accordance with their respective terms.

        16.    There is no action, suit, investigation or proceeding (whether or
               not purportedly on behalf of Guarantor) pending or threatened
               against or affecting Guarantor or any of its assets (a) which
               involves the Collateral or the Pledge Stock or any of the
               transactions contemplated by the Agreement, the Guaranty, the
               Pledge Agreement, the Stock Powers and all other instruments to
               be executed and delivered pursuant thereto; or (b) which, if
               adversely determined, could have an adverse effect upon the
               transactions contemplated by the Agreement or a material adverse
               effect on the business, operations or financial condition of
               Guarantor.

        17.    On the Closing Date Guarantor shall have good and marketable
               title to the Pledged Stock subject to no Liens except the
               security interest created by the Pledge Agreement in favor of
               Lender.

        18.    On the Closing Date Lender shall have a legal, valid and
               continuing first and only priority security interest in the
               Pledged Stock, free and clear of all other Liens, and all
               filings, recordings or other actions necessary or desirable in
               order to establish, protect and perfect such security interest in

               all taxes, fees and other charges in connection therewith shall
               have been duly paid.

               which after the giving of notice

               or lapse of time or both would constitute an event of default,
               under any mortgage, indenture, contract, agreement, judgment or
               other undertaking to which Guarantor is a party or which purports
               to be binding upon Guarantor or upon any of its assets, except
               for any such default, event or condition which, individually or

               Guaranty, the Pledge Agreement, the Stock Powers or all other
               instruments to be executed and delivered pursuant thereto and to

change the basis of taxation of payments by the Debtor to the Lender in respect
of the Loan (other than any tax on or measured by the overall net income of the
Lender); or

         (b) impose, modify or hold applicable any reserve, special deposit or
similar requirement against assets of, deposits or other liabilities of or for
the account of, or loans or commitments by, the Lender with respect to the Loan
(including without limitation any reserves against "Eurocurrency Liabilities"

Federal Reserve System); or

         (c) impose on the Lender any other condition with respect to the Loan
or its obligation to make and maintain the Loan; and the result of any of the
foregoing is to increase the cost to the Lender of making or maintaining such
Loan or to reduce the amount of any sum received or receivable by the Lender
under this Agreement or the Note issued to the Lender, then the Debtor shall pay
to the affected Lender on demand from time to time such additional amounts as
may be necessary to reimburse the Lender for such increased cost or to
compensate the Lender for such reduced amount; provided, however, that upon the
Debtor's payment of such increased cost or compensation to the Lender, the
Debtor shall have the option to prepay the Note in full at the time of its
payment of any such increased cost or compensation with no prepayment penalty at
such time only. A certificate, calculating in reasonable detail the amount of
such increased cost or reduced amount, shall be submitted to the Debtor by any
affected Lender, and shall, absent manifest error, be final, conclusive and
binding for all purposes.

        2.6 Capital Adequacy. If any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any governmental agency or
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Lender with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, in the Lender's
reasaonable determination (which determination shall be conclusive and binding)
has the effect of increasing the amount of capital required to be maintained by
the Lender or reducing the rate of return on capital as a consequence of its
agreement to make, or its making of, the Loan pursuant to this Agreement to a
level below that which the Lender could have achieved but for such adoption,
change or compliance (taking into consideration policies with respect to capital
adequacy) by an amount reasonably deemed by the Lender to be material, then,
upon demand by the Lender, the Debtor shall pay to the Lender, from time to time
as specified by the Lender, such additional amounts which shall be sufficient to
compensate the Lender for the cost of such additional capital or reduced rate of
return; provided, however, that upon the Debtor's payment of such additional
amounts or compensation to the Lender, the Debtor shall have the option to
prepay the Note in full at the time of its payment of any such additional
amounts or compensation with no prepayment penalty at such time only. A
certificate calculating in reasonable detail the amount of any such cost or
reduced rate of return, submitted to the Debtor by any such affected Lender,
shall, absent manifest error, be final, conclusive and binding for all purposes.

        2.7 Illegality. In the event that the Lender shall have reasonably
determined that the making or continuation of the Loan 



                                       12
<PAGE>   13

is or has become unlawful or interferes with or prevents compliance by the
Lender in good faith with any applicable law, governmental rule, regulation,
guideline or order (whether or not having the force of law or whether or not
failure to comply therewith would be unlawful), the Lender shall promptly give
notice to the Debtor of such determination. The Debtor shall, on the next
Installment Payment Date after notice of any such determination or earlier if
required by law, repay the entire Loan, together with all interest accrued
thereon and all other amounts payable hereunder and under the Note with no
prepayment penalty at such time only.

        2.8 Funding Losses. If the Debtor fails to fulfill the conditions set
forth in Sections 2.5, 2.6, and/or 2.7 of this Agreement by the time specified
for their fulfillment or otherwise fails to borrow the Loan after delivering a
notice with respect thereto, then the Debtor shall pay the Lender the amount of
any losses, costs and expenses reasonably incurred as a consequence thereof,
including any loss of margin or expenses incurred in liquidating or re-employing
deposits or other funds acquired to make such Loan. A certificate, calculating
in reasonable detail the amount of any such losses, costs and expenses,
submitted to the Debtor shall, absent manifest error, be final, conclusive and
binding for all purposes.

        2.9 Method of Payment. The Debtor shall make each payment due under this
Agreement and under the Note to the Lender at its Head Office or at such other
place as the Lender may from time to time designate in writing not later than
2:00 P.M. (Rhode Island time) on the date when due in lawful money of the United

Account Number: 015-5527767, For: Fleet Capital Corporation, Reference Credit:

(including, without limitation, any time at which any amount is due under this
Agreement) any amount due under this Agreement or the Note, including, without
limitation, principal, interest, fees and charges, against any account of the
Debtor with the Lender (other than any payments or amounts held in the Account
which are solely Maintenance Fees or Security Deposits which payments or amounts
shall be disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13
of this Agreement). Whenever any payment to be made under this Agreement or
under the Note shall be stated to be due on a Saturday, Sunday or a public
holiday, or the equivalent for banks generally under the laws of the State of
Rhode Island or California, such payment shall be made on the next succeeding
Business Day, and such extension of time shall be included in the computation of
the payment of interest.

hereunder will violate or result in a violation of the Securities Exchange Act

of this Agreement and to establish and protect the rights, interests and
remedies created, or intended to be created, in favor of Lender hereby,
including, without limitation, the execution, delivery, recordation and filing

dispose, assign, sublease, pledge, mortgage, exchange, lease or otherwise
relinquish possession or dispose of any of its now owned or hereafter acquired

<PAGE>   28

security interest in the Collateral), except (i) for the Lease and the leasing

        (b)     Liens for taxes or assessments or other government charges or
                levies not yet due and payable or, if due and payable, Liens for

                proceedings and for which appropriate cash reserves are
                maintained, and where in the Lender's sole judgment, there is no
                danger of the sale, forfeiture or loss of any of the Collateral,

                course of business which do not exceed in the aggregate
                $100,000.00 and which are not past due for more than thirty (30)
                days, unless such Liens are being diligently contested in good
                faith by appropriate proceedings and appropriate cash reserves

        (a) Maintenance and Operation. Debtor, at its own cost and expense,
shall (or shall cause the Lessee to) (i) maintain, inspect, service, repair,
overhaul and test the Engine in accordance with the manufacturer's maintenance
program and (w) an FAA approved Part 121 maintenance program, (x) all
maintenance manuals initially furnished with the Engine, if any, including any
subsequent amendments or supplements to such manuals issued by the applicable
manufacturer from time to time, (y) all "mandatory", "alert" and (to the extent
applicable to Debtor, or its operations) "highly recommended" or other service
bulletins, modification kits, and similar notices and components issued,
supplied, or available by or through the manufacturer and/or the manufacturer(s)
of the Engine or Part with respect to the Engine and (z) all "airworthiness
alerts" and "Airworthiness" or other "Directives", "Service Letters",
"Circulars" and "Operator Bulletins" and all other applicable service,
maintenance, repair and overhaul regulations issued by the FAA or similar
regulatory agency having jurisdictional authority, and whenever possible causing
compliance to the foregoing to be completed through corrective modification in
lieu of operating manual restrictions; (ii) maintain all Records and all other
records, logs, and other materials required by the FAA to be maintained in
respect of the Engine, or by the manufacturer thereof for enforcement of any
warranties. Without limiting the generality of the foregoing, Debtor shall (or
shall cause the Lessee to) maintain, inspect, service, repair, overhaul and test
the Engine, and furnish all



                                       29
<PAGE>   30

parts, replacements, mechanisms, devices and servicing required therefor, so
that the value, condition and operating efficiency of the Engine shall at all
times be maintained and preserved at a level which is the higher of, (x) its
value, condition and operating efficiency when delivered to Debtor, fair wear
and tear excepted, or (y) the level required by any governmental authority
having jurisdiction with respect thereto, or as shall be required by any and all
applicable "airworthiness alerts" and "Airworthiness" or other "Directives",
"Service Letters", "Circulars" and "Operator Bulletins". All maintenance
procedures required under this Section 5.11(a) or any other provision of this
Agreement shall be undertaken and completed in accordance with all FAA standards
and procedures and all manufacturer recommended procedures, as well as the
procedures established by Debtor for similar engines which it owns or leases,
and only by properly trained, licensed, and certified maintenance sources and
maintenance personnel, so as to keep the Engine in good operating condition,
ordinary wear and tear alone excepted. Debtor shall not (and shall cause the
Lessee not to) permit the Engine to be serviced, repaired, maintained, used or
operated in any manner contrary to directives of the FAA or the manufacturer's
operating manuals or instructions, or in violation of the manufacturer's
specifications, service bulletins or other requirements, including, without
limitation, such of the manufacturer's requirements as may be applicable to keep
in full force and effect each warranty, product or performance guaranty, service
life policy or the like. Notwithstanding anything contained in this Section
5.11(a) to the contrary, so long as the Debtor shall (or cause the Lessee to)
maintain, inspect, service, repair, overhaul and test the Engine (and maintain
and keep any Records) at a level which fully satisfies in all respects the terms
and conditions of the Lease, the Debtor shall be deemed to have complied in all
respects to the terms and conditions of this Section 5.11(a).

        (b) Compliance and Use. The Engine shall be maintained, used and
operated by Debtor (or the Debtor shall cause the Lessee to) maintain, use and
operate the Engine, in compliance with any and all statutes, laws, ordinances,
regulations and mandatory standards, letters, circulars, bulletins, instructions
or directives issued by any governmental agency applicable to the maintenance,
use or operation thereof, in compliance with any certificate, license or
registration relating to the Engine issued by any agency, and in a manner that
does not modify or impair any existing warranties on the Engine or any part
thereof. Debtor shall also (or shall cause the Lessee to) operate the Engine
solely in the conduct of its business and/or for commercial purposes, and Debtor
shall not (and shall cause the Lessee not to) operate or permit the Engine to be
operated at any time or in any geographic area when or where insurance required
by the provisions of Section 5.12 hereof shall not be in effect or excluded from
coverage, or in any recognized or threatened area of hostilities unless fully
covered to Lender's satisfaction by hull, war, and political risk insurance, or
any area in which Lender's first lien on the Engine may be jeopardized or not
recognized, as determined 



                                       30
<PAGE>   31

in Lender's sole judgment, or in a manner, for any time period, such that, any
third party shall be deemed to have "operational control" of the Engine, except
for the Lessee pursuant to the terms of the Lease. Notwithstanding anything
contained in this Section 5.11(b) to the contrary, so long as the Debtor shall
(or cause the Lessee to) use, operate, maintain, inspect, service, repair,
overhaul and test the Engine (and maintain and keep any Records) at a level
which fully satisfies in all respects the terms and conditions of the Lease, the
Debtor shall be deemed to have complied in all respects to the terms and
conditions of this Section 5.11(b).

        (c) Identification. If requested by Lender in writing, Debtor shall, at
its own cost and expense (or the Debtor shall cause the Lessee, at the Lessee's
own cost and expense to), attach to the Engine a data plate satisfactory to
Lender disclosing Lender's security interest in the Engine.

        (d) Replacement Parts. Debtor, at its own cost and expense, will
promptly (or will cause the Lessee to promptly) replace all Parts which may from
time to time become worn out, lost, stolen, taken, destroyed, seized,
confiscated, requisitioned, damaged beyond repair or permanently rendered or
declared unfit for use for any reason whatsoever (such substituted Parts
hereinafter called "Replacement Parts"). In addition, in the ordinary course of
maintenance, service, repair, overhaul or testing, Debtor may, at its own cost
and expense, (or may cause the Lessee to promptly) remove serviceable Parts,
provided that Debtor shall, at its own cost and expense (or Debtor shall cause
the Lessee, at the Lessee's own cost and expense to), replace such serviceable
Parts as promptly as practicable. All Replacement Parts (i) shall be owned by
Debtor or Lessee free and clear of all Liens (other than the Lien of the Lender
hereunder), (ii) shall be in an airworthy condition and of at least equivalent
model and modification status and/or service bulletin accomplishment status,
shall be fully interchangeable as to form, fit and function and shall be in a
good operating condition as, and shall have a value and utility at least equal
to, the Parts replaced assuming such replaced Parts were in the condition and
repair required to be maintained by the terms hereof, (iii) shall have a current
"serviceable tag" of the manufacturer or maintenance facility providing such
items to Debtor or Lessee, indicating that such Parts are new, serviceable or
overhauled, (iv) if serviceable, shall have all maintenance records from the
last overhaul thereof and the maintenance history since the last overhaul
thereof, (v) if overhauled, have all overhaul records, and (vi) if a life
limited Part, have continuous records since the date of manufacture or the date
of the last overhaul. All Parts at any time removed from the Engine shall remain
part of the Collateral, no matter where located, until such time as such Parts
shall be replaced by Parts which have been incorporated or installed in or
attached to the Engine and which meet the requirements for Replacement Parts
specified above. Without limiting the generality of any term of this Agreement,
immediately upon any Replacement Part becoming incorporated or



                                       31
<PAGE>   32

installed in or attached to the Engine as above provided, without further act,
such Replacement Part shall become subject to this Agreement including, without
limitation, the lien and security interest of this Agreement, and shall be
deemed part of the Collateral and shall be deemed part of the Engine, as the
case may be, for all purposes hereof to the same extent as the Parts originally
incorporated or installed in or attached to the Engine, and the Lender's lien
and security interest with respect to the Part being replaced by the Replacement
Part shall automatically thereafter be deemed to be released and shall no longer
be subject to the terms of this Agreement. Notwithstanding anything contained in
this Section 5.11(d) to the contrary, so long as the Debtor shall (or cause the
Lessee to) use, operate, maintain, inspect, service, repair, overhaul and test
the Engine and replace any Parts (and maintain and keep any Records) at a level
which fully satisfies in all respects the terms and conditions of the Lease, the
Debtor shall be deemed to have complied in all respects to the terms and
conditions of this Section 5.11(d).

        (e) Additions; Modifications. Debtor (or the Lessee) shall be entitled
from time to time during the term of this Agreement to, at Debtor's or Lessee's
sole cost and expense, make such alterations, modifications, additions to or
removals from any Engine or Engine as may be reasonable in the proper conduct by
Debtor (or the Lessee, as applicable) of its business; provided, that in no
event shall any such alteration, modification, addition or removal (i) impair
the originally intended function or use of the Engine or diminish the use,
condition or value of the same, assuming the Engine was in the condition and
repair then required to be maintained by the terms hereof, and/or (ii) as to any
Additional Parts (as such term is defined below), the removal of any such
Additional Parts can be readily removed without causing material damage to the
Engine. All Parts incorporated or installed in or attached to the 



                                       32
<PAGE>   33

Engine as the result of such alteration, modification or addition shall be
collectively referred to as the "Additional Parts". Debtor shall (or shall cause
the Lessee to) repair all damage to the Engine resulting from any installation
and/or removal of any Additional Parts so as to restore the Engine to its
condition prior to installation, normal wear and tear excepted assuming the
Engine was in the condition and repair then required to be maintained by the
terms hereof. Any alterations or modifications with respect to the Engine that
may at any time during the term of this Agreement be required to comply with
applicable law or any governmental rule or regulation shall be made at the sole
cost and expense of Debtor or Lessee, as applicable. Without limiting the
generality of any term of this Agreement, immediately upon any Additional Parts
becoming incorporated or installed in or attached to the Engine as above
provided, without further act, such Additional Parts shall become subject to
this Agreement including, without limitation, the lien and security interest of
this Agreement, and shall be deemed part of the Collateral and shall be deemed
part of the Engine, as the case may be, for all purposes hereof to the same
extent as the Parts originally incorporated or installed in or attached to the
Engine; provided, that if such Additional Part was in addition to, and not a
replacement of or substitution for, any Part incorporated or installed in or
attached or added to the Engine on the date the Engine became subject to the
terms of this Agreement (a "Debtor Additional Part"), Debtor may (or may cause
the Lessee to) at any time remove such Debtor Additional Part from the Engine so
long as the removal of such Debtor Additional Part (i) does not impair the
originally intended function or use of the Engine or diminish the use, condition
or value of the same, assuming the Engine was in the condition and repair then
required to be maintained by the terms hereof, and/or (ii) can be readily
removed without causing material damage to the Engine, and upon removal of such
Debtor Additional Part, Lender's lien and security interest with respect to such
Debtor Additional Part shall automatically be deemed to be released and shall no
longer be subject to the terms of this Agreement. Notwithstanding anything
contained in this Section 5.11(e) to the contrary, so long as the Debtor shall
(or cause the Lessee to) use, operate, maintain, inspect, service, repair,
overhaul and test the Engine and make additions or modifications to the Engine
or any Parts (and maintain and keep any Records) at a level which fully
satisfies in all respects the terms and conditions of the Lease, the Debtor
shall be deemed to have complied in all respects to the terms and conditions of
this Section 5.11(e).

        5.12   Insurance.

        (a) Engine Liability and Property Damage Insurance. Debtor represents
and warrants that it will (or will cause the Lessee to) maintain at all times,
at its own cost and expense (or at the Lessee's own cost and expense), with
insurers of recognized responsibility, (i) comprehensive aircraft and general
public liability insurance against bodily injury and property damage claims in
an amount not less than $300,000,000.00 for each single occurrence and (ii) such
other property damage insurance (exclusive of manufacturer's product liability
insurance) with respect to the Engine as is of the type and in the amounts
usually carried by companies engaged in the same or a similar business as Debtor
(or Lessee), similarly situated with Debtor (or Lessee), and owning or operating
similar aircraft and engines, and which covers risks of the kind customarily
insured against by such companies.

        (b) Insurance Against Loss or Damage to the Engine. Debtor represents
and warrants that it will (or will cause the Lessee to) maintain in effect at
all times, at its own cost and expense (or at the Lessee's own cost and
expense), with insurers of recognized responsibility, all-risk ground and flight
aircraft hull insurance covering the Engine, provided that such insurance shall
at all times be not less than the greater of (i) the full replacement value of
the Engine, which replacement value shall be the express amount provided for
each twelve (12) month period set forth on Exhibit C attached hereto, (ii) the
aggregate unpaid 



                                       33
<PAGE>   34

principal amount of the Note or (iii) the amount which would be paid pursuant to
Section 2.3 hereof upon the occurrence of an Event of Loss (each such amount
determined as of each anniversary of the Closing Date for the next succeeding
year throughout the term of this Agreement). Debtor shall (or shall cause the
Lessee to), at its (or the Lessee's) own cost and expense, additionally maintain
in effect with an insurer of recognized responsibility reasonably satisfactory
to Lender, hijacking (air piracy) insurance with respect to the Engine in a face
amount of not less than the greater of (i) the full replacement value of the
Engine, which replacement value shall be the express amount provided for each
twelve (12) month period set forth on Exhibit C attached hereto, (ii) the
aggregate unpaid principal amount of the Note or (iii) the amount which would be
paid pursuant to Section 2.3 hereof upon the occurrence of an Event of Loss
(each such amount determined as of each anniversary of the Closing Date for the
next succeeding year throughout the term of this Agreement), which shall be in
full force and effect throughout any geographical areas at any time traversed by
the Engine. Such insurance shall also include governmental confiscation and
expropriation and related insurance, if and to the extent the same is maintained
by Debtor (or Lessee, as applicable) with respect to other aircraft owned or
operated by Debtor (or Lessee, as applicable) on the same routes as the Engine
or where the custom in the United States airline industry is to carry such
insurance with respect to aircraft and engines operated on the same routes as
the Engine.

        (c) Lender as Additional Insured; Notice. Any policies of insurance
carried in accordance with this Section and any policies taken out in
substitution or replacement or any such policies (i) shall be amended to name
Lender as the additional insured as its interests may appear, (ii) with respect
to insurance carried in accordance with paragraph (b) of this Section 5.12
covering the Engine, shall provide that any amount(s) payable thereunder which
exceed $200,000.00 in the aggregate shall be paid directly to Lender as sole
loss payee and not to Lender and Debtor jointly (and, so long as no Event of
Default has occurred, such amounts shall be disbursed by Lender to Debtor or
other appropriate persons for payment of the costs actually incurred with
respect to repairs made to the Engine so as to restore it to the operating
condition required hereunder, or shall be disbursed by Lender as otherwise
required by this Agreement), and that any amount(s) of less than $200,000.00 in
the aggregate shall be paid to Debtor (and such amounts shall be applied by
Debtor to pay the costs of such repairs) provided, however, that if an Event of
Default has occurred, any and all such proceeds or amounts shall be paid
directly to Lender to be applied pursuant to the applicable terms of this
Agreement, (iii) shall provide that if any insurer cancels such insurance for
any reason whatever, or any substantial change is made in any of the coverage
required hereunder, or the same is allowed to lapse for nonpayment of premium or
such insurance coverage is reduced, such cancellation, change, lapse or
reduction shall not be effective as to Lender for thirty (30) days following
receipt by Lender of written notice, and (iv) shall provide that 



                                       34
<PAGE>   35

in respect of the interests of Lender in such policies, the insurance shall not
be invalidated by any action or inaction of Debtor or any other Person (other
than Lender). Each insurance policy and its respective cover amount(s) obtained
in accordance with the requirements set forth in paragraphs (a) and (b) of this
Section 5.12 shall (i) be primary insurance, not subject to any co-insurance
clause and shall be without right of contribution from any other insurance, and
(ii) expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured or loss payee, and shall waive any right of such insurer
to any setoff, counterclaim or other deduction, by attachment or otherwise, in
respect of Lender or Debtor. Debtor shall arrange for appropriate certification
as to the satisfaction of the requirements set forth above in this Section 5.12
to be delivered to Lender not later than the Closing Date.

        (d) Reports, etc. Upon the request of the Lender, Debtor shall furnish
to Lender a report describing in reasonable detail the insurance then carried
and maintained on the Engine and certifying that such insurance complies with
the terms hereof and such other evidence of insurance coverage that the Lender
reasonably requests. In the event Debtor shall fail to maintain insurance as
herein provided, Lender may, at its option, provide such insurance, and Debtor
shall, upon demand, reimburse Lender for the cost thereof, together with
interest at the Late Charge Rate from the date of payment through the date of
reimbursement.

        (e) Agreed Value. Anything herein to the contrary notwithstanding, at
all times while the Engine is subject to this Agreement, the insurance required
by Section 5.12 of this Agreement shall be for an amount on an "agreed value"
basis not less than the greater of (i) the full replacement value of the Engine,
which replacement value shall be the express amount provided for each twelve
(12) month period set forth on Exhibit C attached hereto, (ii) the aggregate
unpaid principal amount of the Note or (iii) the amount which would be paid
pursuant to Section 2.3 hereof upon the occurrence of an Event of Loss (each
such amount determined as of each anniversary of the Closing Date for the next
succeeding year throughout the term of this Agreement).

        5.13 Indebtedness. Debtor shall not create, incur, assume, or suffer to
exist any recourse or nonrecourse Indebtedness, except:

        (a)     Indebtedness of the Debtor under this Agreement or under any
                other agreement, instrument or document with or in favor of the
                Lender; and

        (b)     Accounts payable to trade creditors for goods or services and
                current operating liabilities (other than for borrowed money),
                in each case incurred in the ordinary course of business and
                paid within the required time, unless diligently contested by
                the 



                                       35
<PAGE>   36

                Debtor in good faith and by appropriate proceedings.

        5.14 Leases. Debtor shall not create, incur, assume, or suffer to exist
any obligation as lessee for the rental or hire of any real or personal
property, except: (a) leases existing on the date of this Agreement and any
extensions or renewals thereof; and (b) leases that do not in the aggregate
require the Debtor to make payments (including taxes, insurance, maintenance,
and similar expense which the Debtor is required to pay under the terms of any
lease) in any fiscal year of the Debtor in excess in the aggregate amount of
$20,000.

        5.15 Sale and Leaseback. Debtor shall not sell, transfer, or otherwise
dispose of any real or personal property to any Person and thereafter directly
or indirectly lease back the same or similar property.

dividends; or purchase, redeem, retire, or otherwise acquire for value any of
its capital stock now or hereafter outstanding or any interests therein; or make
any distribution of assets to its shareholders as such whether in cash, assets,
or obligations of the Debtor; or alleviate or otherwise set apart any sum for
the payment of any dividend or distribution on, or for the purchase, redemption,
or retirement of, any shares of its capital stock or any interests therein; or

loan or advance of any kind whatsoever to any Person, or purchase or otherwise
acquire any capital stock, assets, obligations, or other securities of, make any

received in settlement of debts (created in the ordinary course of business)
owing to the Debtor.

property or the rendering of any service, with any Affiliate, except in the

shall not waive any provisions of, or modify or amend, the Lease or the General
Terms Agreement in any way whatsoever, nor shall Debtor have authority to

by the Lessee;

        (d) using its best efforts, upon the request of the Lender in its sole

Person 



                                       38
<PAGE>   39

that is not an Affiliate shall be subject to the prior written consent of
the Lender, which consent shall not be unreasonably withheld, provided further,
however, that any lease or sale of the Engine proposed by the Debtor to any

furnish to Lender from time to time such information relating to the Collateral,
the Debtor or the Guarantor (or their respective Subsidiaries and/or
Affiliates), financial or otherwise, as Lender shall reasonably request;

Engine, 



                                       39
<PAGE>   40

Engine which may be in the Debtor's possession or control.

        SECTION 6. SECURITY INTEREST.

        6.1 Grant of Security Interest. As collateral security for the prompt
and complete payment and performance when due of all of the Obligations and in
order to induce Lender to enter into this Agreement and make the Loan to Debtor
in accordance with the terms hereof and to extend other credit from time to time
to Debtor, whether under this Agreement, the Note or otherwise, Debtor hereby
assigns, conveys, mortgages, pledges, hypothecates and transfers to Lender, and
hereby grants to Lender a present and continuing first priority security
interest in and lien on all of Debtor's right, title and interest in, to and
under the Collateral; but none of Debtor's (and/or any other party's of any kind
whatsoever) obligations, liabilities and/or duties of any kind whatsoever under,
or with respect to the Collateral. Notwithstanding anything to the contrary
contained herewith or otherwise, the Lender does not by virtue of this
Agreement, the Collateral Assignment or otherwise assume any obligations,
liabilities and/or duties of any kind whatsoever of the Debtor (and/or of any
other party of any kind whatsoever) under, or with respect to, the Collateral
and the Lender shall not be responsible in any way whatsoever for the
performance by the Debtor (and/or by any other party of any kind whatsoever) in
connection with, relating to, or arising under, the Collateral.

        The security interest granted herein shall attach to each item of
Collateral at the time Debtor has any interest of any kind whatsoever in such
Collateral without any further action of any kind whatsoever.

        6.2 Lender Appointed as Attorney-in-Fact.

        (a) Debtor hereby irrevocably constitutes and appoints Lender and any
other officer or agent thereof, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of Debtor and in the name of Debtor or in its own name, from time to
time in Lender's discretion, for the purpose of carrying out the terms of this
Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Agreement. Debtor hereby ratifies all that said attorney shall
lawfully do or cause to be done by virtue hereof. To the extent permitted by
law, this power of attorney is a power coupled with an interest and shall be
irrevocable. Without limiting the generality of the foregoing, pursuant to such
appointment, the Lender shall have authority (i) to endorse Debtor's name on any
checks, notes, drafts or any other payments or instrument relating 



                                       40
<PAGE>   41

to the Collateral which come into the Lender's possession or control, (ii) to
execute, sign, file and record UCC financing statements, UCC amendments and
other lien recordation documents with respect to any Collateral, and (iii) to
settle insurance claims with the applicable insurer and/or to collect any
insurance proceeds from the applicable insurer in connection with any casualty
occurrence or Event of Loss.

        (b) The powers conferred on Lender hereunder are solely to protect its
interest in the Collateral and shall not impose any duty upon it to exercise any
such powers. Lender shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers and neither it nor any of
its officers, directors, employees or agents shall be responsible to Debtor for
any act or failure to act.

        SECTION 7. EVENTS OF DEFAULT.

        The term "Event of Default", wherever used herein, shall mean any of the
following events or circumstances (whatever the reason for such Event of Default
and whether it shall be voluntary or involuntary, or come about or be effected
by operation of law, or be pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation or any
administrative or governmental body):

full force and effect any of the insurance required under this Agreement, or
shall (or the Lessee shall) operate or permit the operation of the Engine at a
time when, or at a place in which, such insurance shall not be in effect; or

        (c) Debtor shall fail (or shall fail to cause the Lessee) to maintain
the Engine in accordance and in compliance with Section 5.11 hereof; or

note, security agreement, equipment lease, title retention, aircraft lease or
conditional sales agreement or any other instrument or agreement evidencing such
indebtedness with Lender or any parent, affiliate or subsidiary of Lender; or
either Debtor or Guarantor shall default in the performance of, or compliance
with, any term contained in any agreement or instrument evidencing or relating
to such indebtedness with Lender or any parent, affiliate or subsidiary of
Lender, if the effect of such default is to cause or permit such indebtedness to
become due prior to its stated maturity, or if any such indebtedness is not 



                                       41
<PAGE>   42

paid at maturity; or Debtor shall otherwise be in default of any of its

the same to occur (except as expressly permitted by Section 5.7 and/or Section
5.8 of this Agreement); or

        (f) either Debtor or Guarantor shall fail to perform or observe any
covenant, condition or agreement (other than those covenants, conditions or

and/or the Guarantor under this Agreement, the Collateral Assignment, the
Guaranty or any agreement, document or certificate delivered by Debtor or the
Guarantor in connection herewith, and such failure shall continue for fifteen
(15) days after written notice thereof from Lender to Debtor and/or Guarantor;
or

        (g) any representation or warranty made by Debtor in this Agreement or
any agreement, document or certificate delivered by Debtor in connection
herewith or pursuant hereto shall prove to have been incorrect, misleading, or
inaccurate in any material respect when such representation or warranty was made
or given (or, if a continuing representation or warranty, at any material time);
or

        (h) any representation or warranty made by Guarantor in the Guaranty,
the Pledge Agreement or any agreement, document or certificate delivered by
Guarantor in connection therewith or pursuant hereto shall prove to have been
incorrect, misleading, or inaccurate in any material respect when such
representation or warranty was made or given (or, if a continuing representation
or warranty, at any material time); or

        (i) either Debtor or Guarantor shall generally fail to pay its debts as
they became due and such failure shall continue for ten (10) Business Days after
written notice by Lender, admit its inability to pay its debts or obligations

Guaranty, as the case may be) providing for the reorganization or liquidation of
corporations, or providing for an assignment for the benefit of creditors, or

the Guarantor's obligations hereunder or under the Guaranty, as the case may
be), as now or hereafter in effect, shall be filed and shall not be withdrawn or
dismissed within sixty (60) days thereafter, or if, under the provisions of any
law (other than any law which does not provide for or permit the readjustment or

and/or the Guarantor or of any substantial part of their respective property and
such jurisdiction, custody or control shall remain in force unrelinquished,
unstayed or unterminated for a period of sixty (60) days; or

        (k) either Debtor or Guarantor shall default in any payment,
indebtedness or other obligation to any Person (other than to the Lender or any
parent, affiliate or subsidiary of Lender) regarding any loan, lease, deferred
purchase price agreement, advancement of credit or any other financing or credit
arrangement or facility of any kind whatsoever (other than those transactions,

this Section 7), if the aggregate amount of such respective payment,
indebtedness or obligation, or if the aggregate amount of the underlying
agreement, indebtedness or obligation regarding any such default, is in excess
of $250,000.00 and such default results in the acceleration of (or the request

the Debtor or the Guarantor in good faith and by appropriate proceedings,
provided, however, any such bona fide dispute and default shall be resolved and
cured within two hundred seventy (270) days after the occurrence of such
default; or

        (m) any judgment, attachment or garnishment against Debtor and/or the

as otherwise expressly permitted with regard to the Guarantor in Section 5.10 of
this Agreement); or

        (o) if the Guarantor shall no longer continue to control one hundred
percent (100%) of Debtor's issued and outstanding stock at all times; or

        (p) if any person or group (as defined in Rules 13d-3 and 13-5 under the
Securities Act), becomes the "beneficial owner" (as defined in Rules 13d-3 and
13d-5 under the Securities Act) of a larger number of shares of common stock of

beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Securities Act);
or

        (q) if either Debtor or Guarantor is a publicly held corporation, there
shall be a change in the ownership of the Debtor's or the Guarantor's, as the
case may be, stock such that the Debtor or Guarantor, as the case may be, is no
longer subject to the reporting requirements of the Securities Exchange Act of
1934, or no longer has a class of equity securities registered under Section 12

the Guarantor.

        Notwithstanding Subsection (r) of this Section 7, Debtor shall have the
right, within ten (10) days after the Debtor has been given notice that a Lessee
Event of Default has occurred under the Lease, to cure, at its sole cost and
expense, any Lessee Event of Default under the Lease relating solely to the
Lessee's failure to pay any Monthly Rent, Maintenance Fees and other payments
expressly due the Debtor by the Lessee thereunder (each a "Lessee Payment
Default") by paying the Lender the applicable Monthly Rent, Maintenance Fees and
such other payments or amounts expressly due the Debtor by the Lessee under the
Lease (any such Monthly Rent, Maintenance Fees and other payments or amounts
hereinafter collectively, the "Lessee Cure Payment") within such ten (10) day
period; provided, however, that the Debtor shall only have the right to cure
three (3) non-consecutive Lessee Payment Defaults during the term of the Lease;
provided further, however, the Debtor shall not have the right to cure any
consecutive Lessee Payment Defaults for any reason whatsoever. The Debtor shall
not, as a result of exercising the right to cure any such Lessee Payment
Default, obtain any Lien on any of the Collateral (including any Monthly Rent,
Maintenance Fees or any other amounts payable under the Lease) for or on account
of any costs or expenses incurred in connection with the exercise of such right,
nor shall any claim of the Debtor against the Lessee or any other party for the
repayment of such costs or expenses impair the prior right and security interest
of the Lender in the Collateral (including any Monthly Rent, Maintenance Fees or
any other amounts payable under the Lease). Upon the receipt by the Lender of
the Debtor's payment of the applicable Lessee Cure Payment (in immediately
available funds), the Lender shall credit and apply any such payment to the
applicable outstanding Obligations, Maintenance Fees, Security Deposits and/or
other amounts required under this Agreement, as the case may be, as provided in
Section 9.1, Section 10.13 or any other applicable section of this Agreement.

        SECTION 8. REMEDIES.

        8.1 Termination of Commitment. If an Event of Default specified in
subsections 7 (i) or (j) above shall occur, then, and in any such event, the
Commitment shall immediately terminate and the principal amount of the Note,
together with accrued interest thereon and all other amounts owing under or with
respect to this Agreement (including, without limitation, any prepayment premium
or fee calculated as of the date of the Event of Default which premium or fee
shall also be due and payable) shall become immediately due and payable without
any notice or other action by Lender, and if any other Event of Default shall
occur and be continuing, then, and in any such event, Lender may (a) terminate
forthwith the Commitment and/or (b) declare the Note to be forthwith due and
payable, whereupon the remaining principal amount of the Note, together with
accrued interest thereon and all other amounts owing under or with respect to
this Agreement 



                                       45
<PAGE>   46

(including, without limitation, any prepayment premium or fee calculated as of
the date of the Event of Default which premium or fee shall also be due and
payable), shall become immediately due and payable without presentment, demand,
protest or other notice of any kind, all of which are hereby expressly waived,
anything contained herein or in the Note to the contrary notwithstanding. During
the continuance of any Event of Default hereunder, Lender shall have the right
to pursue and enforce any of its rights and remedies under Section 8,
Subsections 8.2 through 8.4, inclusive, hereof.

        8.2 Additional Remedies. Upon the occurrence of any Event of Default,
Lender may, at its sole option and discretion, in addition to any other rights
or remedies granted to it under this Agreement, at law or in equity or under any
other instrument or agreement securing, evidencing or relating to the
Obligations, exercise one or more of the following remedies with respect to any
or all of the Collateral: (a) cause Debtor to, at Debtor's expense, promptly
return such Collateral (or any portion thereof requested by Lender) to such
location as Lender may from time to time reasonably designate, or Lender, at its
option, may enter upon the premises where the Collateral (or any portion thereof
requested by Lender) is located and take immediate possession of and remove the
same by self-help (to the extent permitted by law), or summary proceedings or
otherwise all without liability to Lender for or by reason of damage to property
or such entry or taking possession; provided, however, that the Lender shall not
remove any Collateral in the possession of the Lessee under the Lease so long as
no default or event of default exists under the Lease; (b) sell any or all of
the Collateral at public or private sale or otherwise dispose of, hold, use,
operate, lease to others or keep idle the Collateral (or any portion thereof),
all as Lender in its sole discretion may determine and all free and clear of any
rights of Debtor; (c) remedy such default, including making repairs or
modifications to any Collateral, for the account of and the expense of Debtor
and Debtor agrees to reimburse Lender for all of Lender's reasonable costs and
expenses; (d) apply any security deposit or other cash collateral or sale or
remarketing proceeds of any Collateral at any time as it sees fit to reduce any
amounts due to Lender (other than any payments or amounts held in the Account
which are solely Maintenance Fees or Security Deposits which payments or amounts
shall be disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13
of this Agreement); and (e) exercise any other right or remedy which may be
available to it under applicable law and the UCC or proceed by appropriate court
action to enforce the terms hereof or to recover damages for the breach hereof.
In addition to the foregoing, Debtor shall continue to be liable for all
indemnities under this Agreement and the Note and for all legal fees and other
costs and expenses resulting from any Event of Default or the exercise of
Lender's remedies. Without limiting the generality of the foregoing, Lender
shall (i) have the right upon any public sale or sales, and, to the extent
permitted by law, upon any such private sale or sales to purchase the whole or
any part of the Collateral 



                                       46
<PAGE>   47

so sold, free of any right or equity of redemption in Debtor, which right or
equity is hereby expressly released, and/or (ii) apply the net proceeds of any
such collection, recovery, receipt, appropriation, realization or sale (after
deducting all reasonable costs and expenses of every kind incurred therein or
incidental to the care, safekeeping or otherwise of any or all of the Collateral
or in any way relating to the rights of Lender hereunder, including attorney's
fees and legal expenses) to the payment in whole or in part of the Obligations,
in such order as Lender may elect and only after so applying such net proceeds
and after the payment by Lender of any other amount required by any provision of
law (including Section 9-504(1)(c) of the UCC), need Lender account for the
surplus, if any, to Debtor. To the extent permitted by applicable law, Debtor
waives all claims, damages, and demands against Lender arising out of the
repossession, retention or sale of the Collateral. Debtor agrees that Lender
need not give more than ten (10) days' notice (which notification shall be
deemed given when mailed, postage prepaid, addressed to Debtor at its address
set forth in Section 10.2. hereof or delivered by overnight delivery service to
the Debtor at such address) of the time and place of any public sale or of the
time after which a private sale may take place and that such notice is
reasonable notification of such matters. Debtor shall be liable for any
deficiency if the proceeds of any sale or disposition of the Collateral are
insufficient to pay all amounts to which Lender is entitled.

        8.3 Costs of Collection. Debtor shall be liable for, and also agrees to
pay, all costs, charges and expenses of Lender, including reasonable attorneys'
fees and disbursements, incurred by or on behalf of Lender with respect to (i)
any Event of Default, (ii) the collection of any of the Obligations, (iii) the
enforcement of any of its respective rights under this Agreement, at law or in
equity or otherwise and/or (iv) the exercise of any of Lender's rights or
remedies under this Agreement, at law or in equity or otherwise.

        8.4 Waivers. Without limiting the generality of any other terms of this
Agreement, Debtor hereby waives presentment, demand, protest or any notice,
except as expressly provided herein, (to the extent permitted by applicable law)
of any kind in connection with this Agreement or any Collateral.

        SECTION 9. ACCOUNT

        9.1 Account.

        (a) All proceeds of checks, notes, cash and other proceeds of the Lease
Receivables as well as all proceeds from the sale of the Engine, any securities
(other than securities issued by Debtor) and any other Collateral and other cash
receipts of every kind and nature (other than the proceeds of any other
borrowing or amount expressly permitted by this Agreement) shall be collected
into any account required by the Lender in its sole 



                                       47
<PAGE>   48

discretion (the "Account") commencing on the date of this Agreement and at all
times hereafter pursuant to the terms of this Section 9.1. The Lender shall
maintain the Account at all times until the Loan and any and all other
Obligations of the Debtor due or owing to the Lender under this Agreement, the
Note, the Collateral Assignment or any agreement, instrument or document
evidencing any other Obligations have been paid in full. Simultaneously with the
Debtor's execution of this Agreement, the Debtor shall direct the Lessee to make
all payments under the Lease directly to the Lender and into the Account. The
Debtor shall hold in trust for Lender and immediately remit to Lender by
depositing the same into the Account all checks, notes, cash and other proceeds
of the Lease Receivables as well as all proceeds from the sale of the Engine,
any securities (other than securities issued by Debtor) and any other Collateral
and other cash receipts of every kind and nature (other than the proceeds of
other borrowing or amount expressly permitted by this Agreement). The Debtor
agrees that all payments or amounts received in the Account will be the sole and
exclusive property of Lender. The Lender shall, on the second (2nd) Business Day
after which any payment or amount is received into the Account, and on a
provisional basis until the final receipt of good funds, (i) credit and apply
all payments or amounts held in the Account which are Monthly Rent to the
applicable monthly principal and interest installment due under the Note and any
other outstanding amounts due or payable under the Note and this Agreement, (ii)
so long as no Lessee Event of Default exists under the Lease, hold all payments
or amounts held in the Account which are solely Maintenance Fees and/or Security
Deposits pursuant to the terms of this Section 9 and/or Section 10.13 of this
Agreement, and (iii) so long as no Event of Default exists under this Agreement,
the Note, the Collateral Assignment or any agreement, instrument or document
evidencing any other Obligations, disburse the remaining amounts held in the
Account (after application to the payments or amounts due or payable under the
Note and this Agreement as provided in subclause (i) above) which are not
Maintenance Fees or Security Deposits expressly due or payable under the Lease
(or are not accrued interest on any Maintenance Fees or Security Deposits) to
the Debtor by wire transfer to Wells Fargo Bank, San Francisco, CA 94163, ABA
No. 121 000 248, Account No. 4518-101423 or to such other address or bank
account requested by the Debtor pursuant to the notice provisions of Section
10.2 of this Agreement. Upon the occurrence of an Event of Default under this
Agreement, the Note, the Collateral Assignment or any agreement, instrument or
document evidencing any other Obligations, the Lender shall, on the second (2nd)
Business Day after which any payment or amount is received into the Account
(other than any payments or amounts held in the Account which are solely
Maintenance Fees or Security Deposits which payments or amounts shall be
disbursed pursuant to the terms of Sections 9.1(b), 9.1(c) and/or 10.13 hereof),
and on a provisional basis until the final receipt of good funds, credit and
apply all such payments or amounts (including, without limitation, any accrued
interest on any amounts contained in the 



                                       48
<PAGE>   49

Account) first, to any amounts due or outstanding under the Note (including,
without limitation, all principal, accrued interest or any prepayment premium or
fee calculated as of the date of the Event of Default which premium or fee shall
also be due and payable), second, the remainder of any such payments or amounts,
if any (or in the event there are no amounts due or outstanding under the Note,
all such payments or amounts shall be applied), to any other amounts due or
payable under this Agreement, the Collateral Assignment, or any amounts due or
outstanding under any agreement, instrument or document evidencing any other
Obligations, and third, the remainder of any such payments or amounts, if any,
to a cash collateral account under the sole dominion and control of Lender until
such Event of Default is cured by Debtor pursuant to the applicable terms of
this Agreement or any other applicable agreement or waived by Lender in its sole
discretion. Any provisional credit hereunder is subject to reversal if the final
collection of a payment is not received by the Lender within five (5) Business
Days following the initial receipt of such payment and will thereafter be
credited when such payment is actually received in good funds. The Debtor agrees
that it shall promptly pay to the Lender $85.00 per month for the Lender's
administration of the Account, together with, if any, all other reasonable fees
charged, and all reasonable expenses incurred, by the Lender in connection with
the administration of the Account. The Lender shall send the Debtor monthly
invoices regarding the $85.00 monthly payment and any other reasonable fees or
expenses charged or incurred in connection with the Lender's administration of
the Account. Without in any way whatsoever limiting the generality of the terms
of this Agreement, the Note, the Collateral Assignment or any other terms and
conditions of any other agreement, instrument or document evidencing any other
Obligations, Debtor hereby irrevocably appoints Lender its attorney-in-fact to
endorse Debtor's name on any checks, notes, drafts or any other payments or
instruments relating to such items (and/or any Collateral) which come into the
Lender's possession or control pursuant to the Account and to take any other
action of any kind whatsoever that the Lender deems necessary or desirable in
its sole discretion regarding the same and/or the Account, including, without
limitation, inserting missing dates on checks, notes, drafts or any other
payments or instruments and/or rejecting and/or returning checks, notes, drafts
or any other payments or instruments, without being liable in any way whatsoever
for wrongful dishonor or any other thing or matter of any kind whatsoever. To
the extent appropriate or permissible under the applicable law, such power is
coupled with an interest and shall be irrevocable. In addition, such power shall
terminate only upon the Debtor's payment and/or performance, as the case may be,
in full of all of the indebtedness and/or obligations of any kind whatsoever
owing or due to the Lender by the Debtor. Neither the Lender nor its counsel
will be liable for any acts or omissions nor error of judgment or mistake of
fact or law in connection with the exercise and/or enforcement of its rights
under this Section 9. Nothing contained in this Agreement, the Collateral
Assignment or any other agreement, instrument or document evidencing any other
Obligations or otherwise or any acts or omissions of the Lender or its counsel
shall be deemed, or construed, in any way whatsoever as the Lender being in
control of the management and/or affairs of the Debtor (other than to exercise
the rights granted to the Lender under this Agreement, the Collateral


                                       49
<PAGE>   50
Assignment or any other agreement, instrument or document evidencing any other
Obligations to, among other things, protect its interest in the Collateral). The
Debtor further agrees that the terms of this Section 9 are in addition to, and
do not in any way whatsoever limit, the terms of this Agreement or any related
cash management or lockbox agreements or documents executed and/or delivered in
connection herewith. However, in the event of a conflict between the terms and
provisions of this Section 9 and any related cash management or lockbox
agreements or documents executed and/or delivered in connection herewith, the
applicable terms and provisions of this Section 9 shall control for all
purposes. Notwithstanding anything to the contrary contained in this Section 9
or otherwise, all payments, funds or amounts received into the Account
(including, without limitation, all Monthly Rent, Maintenance Fees and Security
Deposits) may also be commingled with the Lender's other funds and no trust
relationship of any kind whatsoever shall exist between the Lender and the
Debtor as to any such payments, funds or amounts so deposited. No interest shall
be payable with regard to any payments, funds or amounts deposited into the
Account except as otherwise expressly provided in Section 9.1(b) hereof.

        (b) The amount of all existing Maintenance Fees and Security Deposits
only held in the Account shall bear interest at a variable rate equal to the
Libor Rate for each Interest Period. Any interest accrued on the Maintenance
Fees and/or the Security Deposits pursuant to the immediately preceding sentence
for any Interest Period shall be credited into the Account on the first day of
each calendar month immediately following said Interest Period or on the first
Business Day of such calendar month (said first day or first Business Day of
each calendar month hereinafter the "Interest Credit Day") so long as any such
Maintenance Fees and/or Security Deposits are required to be maintained in the
Account pursuant to the terms of this Section 9. The Maintenance Fees and/or the
Security Deposits (including, without limitation, any accrued interest thereon),
shall not be released 


                                       50
<PAGE>   51

and/or disbursed to the Debtor (or any other party) until any and all
obligations outstanding under the Note, the Collateral Assignment and this
Agreement (other than any obligations relating solely to any other agreement,
instrument or document between the Debtor and the Lender) have been fully paid
and/or performed, as the case may be, except as otherwise expressly provided in
Section 9.1(c) hereof, provided, however, that upon the occurrence of any Event
of Default under this Agreement, the Note, the Collateral Assignment or any
agreement, instrument or document evidencing any other Obligations, the
Maintenance Fees and the Security Deposits (including, without limitation, any
accrued interest thereon), shall not be released and/or disbursed to the Debtor
until any and all Obligations outstanding by the Debtor under this Agreement,
the Note, the Collateral Assignment or any other agreement, instrument or
document between the Debtor and the Lender have been fully paid and/or
performed, as the case may be, except as otherwise expressly provided in Section
9.1(c) hereof; provided further, however, that nothing contained in the
foregoing proviso shall be deemed to limit, impair or adversely affect in any
way whatsoever the Lender's rights under this Agreement, the Collateral
Assignment or any other agreements, documents or instruments to set off, debit
or apply any Maintenance Fees, Security Deposits or any other amounts as
provided in Section 9.1(c) or Section 10.13 of this Agreement or any other
applicable section of this Agreement.

        (c) So long as no Lessee Event of Default exists under the Lease, upon
three (3) Business Days prior written notice by the Debtor to the Lender for the
release of any Maintenance Fees which are being held in the Account, and receipt
by the Lender from the Debtor of such documents (including, without limitation,
such documents required to be supplied by the Lessee under the Lease or the
General Terms Agreement relating to any such amounts) as the Lender shall
reasonably request to document the Lessee's right to such Maintenance Fees, the
Lender shall disburse directly to the Lessee (or the applicable vendor, supplier
or maintenance company performing the applicable maintenance work or to the
Debtor if the Debtor has already paid for any such maintenance work) on behalf
of the Debtor the amount of any Maintenance Fees which the Lender expressly
agrees shall be released from the Account (which approval or agreement shall be
in the reasonable determination of the Lender). Upon and after the occurrence of
a Lessee Event of Default under the Lease (but without limiting any rights of
the Lender to debit, apply or set off any amounts in the Account which are not
Maintenance Fees or Security Deposits, including, without limitation, all
Monthly Rent and accrued interest in the Account), the Lender shall have the
absolute right to immediately debit the Account for any Maintenance Fees and
Security Deposits (and the amounts in the Account relating to Maintenance Fees
and Security Deposits shall be immediately released accordingly), and apply the
proceeds thereof first, to any amounts due or outstanding under the Note
(including, without limitation, all principal, accrued interest or any
prepayment premium or fee calculated as of the date of the Event of Default
which premium or fee shall also be due and payable), second, the remainder of
any such amounts, if any, to any other amounts due or payable under this
Agreement, the Collateral Assignment, or any amounts due or outstanding under
any agreement, instrument or document evidencing any other Obligations, and
third, the remainder of any such amounts, if any, to a cash collateral account
under the sole dominion and control of Lender until such Event of Default is
cured by Debtor pursuant to the applicable terms of this Agreement or any other
applicable agreement or waived by Lender in its sole discretion; provided,
however, that in the event the Debtor exercises its 



                                       51
<PAGE>   52

right to cure three (3) non-consecutive Lessee Payment Defaults and pays the
Lender the applicable Lessee Cure Payment pursuant to the terms of the last
paragraph of Section 7 of this Agreement, upon the receipt by the Lender of the
Debtor's payment of the applicable Lessee Cure Payment (in immediately available
funds), the Lender shall credit any amounts into the Account which the Lender
has set off or debited against Maintenance Fees or Security Deposits only with a
corresponding amount from the Debtor's payment of the applicable Lessee Cure
Payment, and effective as of any such credit such amounts shall be deemed
Maintenance Fees and/or Security Deposits, as the case may be, and, if
applicable, the Lender shall also credit or apply any remaining amounts of such
payment as provided in Section 9.1(a), Section 9.1(b) or Section 10.13 of this
Agreement or any other applicable section of this Agreement.

        SECTION 10. MISCELLANEOUS.

        10.1 No Waiver; Cumulative Remedies. No failure or delay on the part of
Lender in exercising any right, power or privilege hereunder or under the Note
shall operate as a waiver thereof, nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
No right or remedy in this Agreement is intended to be exclusive but each shall
be cumulative and in addition any other remedy referred to herein or otherwise
available to Lender at law or in equity; and the exercise by Lender of any one
or more of such remedies shall not preclude the simultaneous or later exercise
by Lender of any or all such other remedies. No express or implied waiver by
Lender of an Event of Default shall in any way be, or be construed to be, a
waiver of any future or subsequent Event of Default. After the occurrence of any
Event of Default, the acceptance by Lender of any installment of principal and
interest or of any other sum owing hereunder or under the Note shall not
constitute a waiver of such Event of Default, regardless of Lender's knowledge
or lack of knowledge thereof at the time of acceptance of any such payment, and
shall not constitute a reinstatement of this Agreement and/or the Note if Lender
has sent Debtor a notice of default, unless Lender shall have agreed in writing
to reinstate this Agreement and/or the Note and waive the Event of Default. To
the extent permitted by law, Debtor waives any rights now or hereafter conferred
by statute or otherwise which limit or modify any of Lender's rights or remedies
under this Agreement and/or the Note.

        10.2 Notices. All notices, requests and demands to or upon any party
hereto shall be deemed to have been duly given or made when received by
overnight delivery service to the address indicated below or when deposited in
the United States mail, return receipt requested first class postage prepaid,

without releasing in any way the obligations or the liability of the Debtor or

thereof) now held or which may hereafter be held as security for this Agreement,
the payment of the Note and/or any Obligations or otherwise to compel the Lender

        10.13 Right of Set Off. Upon the occurrence of an Event of Default under
this Agreement, the Lender is hereby authorized at any time and from time to
time without notice to the Debtor or any other party (any such notice being
expressly waived by the Debtor), to set off and apply any and all deposits
(general or special, time or demand, provisional or final) of any kind
whatsoever at any time held, including, without limitation, any amounts or
proceeds (including, without limitation, any accrued interest) contained in the
Account (other than any Maintenance Fees or Security Deposits as expressly
provided below), and other indebtedness at any time owing by the Lender to or
for the credit or the account of the Debtor against any and all of the
obligations of the Debtor now or hereafter existing under this Agreement, the
Note, the Collateral Assignment or any agreement, document or instrument
evidencing any other Obligations, irrespective of whether or not the Lender
shall have made any demand under this Agreement, the Note, the Collateral
Assignment or any agreement, document or instrument evidencing any other
Obligations, and although such obligations may be unmatured; provided, however,
that the Lender shall not be authorized to set off any amounts in the Account
which are solely Maintenance Fees and/or Security Deposits without notice to the
Debtor or any other party until after the occurrence a Lessee Event of Default
under the Lease, and upon the occurrence of any such Lessee Event of Default,
the Lender shall have the right to set off and apply any and all Maintenance
Fees and/or Security Deposits without notice to the Debtor as provided in this
Section 10.13; provided further, however, that in the event the Debtor exercises
its right to cure three (3) non-consecutive Lessee Payment Defaults and pays the
Lender the applicable Lessee Cure Payment pursuant to the terms of the last
paragraph of Section 7 of this Agreement, upon the receipt by the Lender of the
Debtor's payment 



                                       56
<PAGE>   57

of the applicable Lessee Cure Payment (in immediately available funds), the
Lender shall credit any amounts into the Account which the Lender has set off or
debited against Maintenance Fees or Security Deposits only with a corresponding
amount from the Debtor's payment of the applicable Lessee Cure Payment, and
effective as of any such credit such amounts shall be deemed Maintenance Fees
and/or Security Deposits, as the case may be, and, if applicable, the Lender
shall also credit or apply any remaining amounts of such payment as provided in
this Section 10.13 or in Section 9.1(a) or Section 9.1(b) of this Agreement or
any other applicable section of this Agreement. The Lender agrees promptly to
notify the Debtor after any such set off and application, provided that the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of the Lender under this Section 10.13 are in addition
to any other rights and remedies of any kind whatsoever (including, without
limitation, other rights of setoff) which the Lender may have.

        10.14 Primary Obligations. Notwithstanding anything to the contrary
contained herein or otherwise, the Debtor shall be, and remain, primarily and

request by the Lender for such consent, and in the event that the Debtor or the
Guarantor do not object in writing to any such request by the Lender within in
such ten (10) Business Day period any such failure to so object shall be deemed
(without any further action of any kind whatsoever) an absolute waiver of the
Debtor's and the Guarantor's rights to object to any such assignment, sale or
transfer; provided further, however, that no consent of any kind of the Debtor
or the Guarantor shall be required for any merger or consolidation between the
Lender or any parent, affiliate or subsidiary of the Lender and any Competitor
of the Debtor or the Guarantor or any Designated Lender of a Competitor of the
Debtor or the Guarantor (or any parent, affiliate or subsidiary of any such
Competitor or Designated Lender). Debtor agrees that the rights hereunder of any
such assignee, lender, creditor, mortgagee, transferee or Person of Lender shall
not be subject to any defense, setoff, recoupment, abatement, reduction, claim
or counterclaim (collectively the "Defenses") that Debtor has or may at any time
have against Lender and/or its agents, employees, officers, directors,
shareholders, subsidiaries, affiliates, successors, and assigns for any reason
whatsoever; and Debtor hereby waives any right to assert at any time any of the

writing, to, among other things, pay all sums due or to become due hereunder or
under the Note and/or the Obligations directly to the assignee, lender,

conditions of this Agreement, the Note and/or the Obligations, and (ii) to
comply with the reasonable demands of any such assignee, lender, creditor,
mortgagee, transferee or Person of Lender in order to perfect any such
assignment or transfer, at Lender's sole expense.

with this Agreement may be instituted or brought in the courts of the State of
Rhode Island or the United States Courts for the District of Rhode Island, as

September __, 1997

Fleet Capital Corporation
50 Kennedy Plaza
Fifth Floor
Providence, Rhode Island 02903

        Re: Engine Loan and Security Agreement

Gentlemen:

        We have acted as general counsel for T-12 Inc., a California corporation
("Debtor"), and Willis Lease Finance Corporation, a California Corporation
("Guarantor") in connection with the execution of the Engine Loan and Security
Agreement of even date (the "Agreement"), between Debtor and Fleet Capital
Corporation ("Lender") and the related transactions contemplated thereby. Terms
not otherwise defined herein shall have the defined meanings set forth in the
Agreement.

        We are familiar with the Debtor and the Guarantor, their respective
affairs, and their respective charter, by-laws, and corporate records. We have
examined originals or copies, certified or otherwise identified to our
satisfaction, or such records, instruments, decisions, certificates, and
documents, have made such inquiries as to questions of fact of officers and
representatives of Debtor and the Guarantor and have made such examinations of
laws, rules, regulations, orders, decrees, writs, judgments, awards,
injunctions, and the like, as are necessary and appropriate for purposes of
giving the opinions hereinafter expressed.

        Based upon the foregoing, it is our opinion:

        1.      Debtor is a corporation duly organized, validly existing and in
                good standing under the laws of the State of California, has the
                necessary authority and power to own the Engine and its other
                assets and to transact the business in which it is engaged, and
                is duly qualified to do business in each jurisdiction in which
                the conduct of its business or the ownership or operation of its
                assets requires such qualification.

        2.      Debtor is a citizen of the United States within


                                       1

<PAGE>   65

                the meaning of Subtitle VII of Title 49 of the United States
                Code, as amended and recodified.

        3.      Debtor has full power, authority and legal right to execute and
                deliver the Agreement, the Note, the Collateral Assignment and
                all other instruments to be executed and delivered pursuant to
                the Agreement, to perform its obligations thereunder, to borrow
                thereunder and to grant the security interest created by the
                Agreement and the Collateral Assignment.

        4.      No consent of any other party (including any partners,
                stockholders, trustees or holders of indebtedness), and no
                consent, license, approval or authorization of, exemption by, or
                registration or declaration with, any governmental body,
                authority, bureau or agency is required in connection with the
                execution, delivery or performance by Debtor of the Agreement,
                the Note, the Collateral Assignment and any other instruments to
                be executed and delivered pursuant to the Agreement, or the
                validity or enforceability of the Agreement, the Note, the
                Collateral Assignment and any other instruments to be executed
                and delivered pursuant to the Agreement, except recordation of

                other undertaking to which Guarantor is a party or which
                purports to be binding upon Guarantor or upon any of its assets,
