                        WILLIS LEASE FINANCE CORPORATION
                                AND SUBSIDIARIES

                   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-K for the fiscal year ended December 31, 1998.

     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 March 31, 1999, and December 31, 1998, and the results of its
operations for the three month periods ended March 31, 1999 and 1998 and its
cash flows for the three month periods ended March 31, 1999 and 1998. The
results of operations and cash flows for the period ended March 31, 1999 are not
necessarily indicative of the results of operations or cash flows which may be
reported for the remainder of 1999.

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.

3.   SHAREHOLDERS' EQUITY

     Authorized capital shares of the Company include 5,000,000 shares of
preferred stock and 20,000,000 shares of common stock with a par value of $0.01
per share. As of March 31, 1999 and December 31, 1998, 7,370,645 and 7,360,813
shares, respectively, of common stock were issued and outstanding. No preferred
stock was issued or outstanding as of March 31, 1999 or December 31, 1998.

     The rights and preferences of preferred stock are established by the
Company's Board of Directors upon issuance.

     The Company has a 1996 Employee Stock Purchase Plan (the "Purchase Plan")
under which 75,000 shares of common stock have been reserved for issuance. This
plan became effective in September 1996. Eligible employees may designate not
more than 10% of their cash compensation to be deducted each pay period for the
purchase of common stock under the Purchase Plan, and participants may purchase
not more than $25,000 of common stock in any one

calendar year. Each January 31 and July 31, shares of common stock are purchased
with the employees' payroll deductions over the immediately preceding six months
at a price per share of 85% of the lesser of the market price of the common
stock on the purchase date or the market price on the date of entry into an
offering period. During the three month period ended March 31, 1999, the Company
issued 4,382 shares of Common Stock as a result of employee stock purchases
under the Purchase Plan.

     Under the 1996 Stock Option/Stock Issuance Plan, as amended and restated 
February 24, 1998, 1,025,000 shares of the Company's shares have been set 
aside to provide eligible persons with the opportunity to acquire a 
proprietary interest in the Company. The plan includes a Discretionary Option 
Grant Program, a Stock Issuance Program, and an Automatic Option Grant 
Program for eligible nonemployee Board Members. During the three month period 
ended March 31, 1999, 7,500 options were exercised. In connection with the 
exercise of a portion of these options, the Company recognized a tax benefit 
of approximately $30,000.

     In conjunction with its initial public offering, the Company sold 
five-year purchase warrants for $0.01 per warrant covering an aggregate of 
100,000 shares of common stock exercisable at a price equal to 130% of the 
initial public offering price. The warrants became exercisable in December 
1997. The warrants' exercise price and the number of shares of Common Stock 
are subject to adjustment to protect the warrant holders against dilution in 
certain events. In February 1998, a holder of 50,000 of the warrants 
exercised the warrants under the net issuance rights of the warrants. Based 
on the closing price on such date, the exercise resulted in the issuance of 
25,238 shares to the holder of the warrants.

4.   FINANCING

     In March 1998, the Company repaid a loan that had residual sharing 
provisions. The repayment resulted in an extraordinary expense of $0.2 
million, net of tax.

5.  COMMITMENTS

    The Company has three leases for its office and warehouse space. The 
annual lease rental commitments are $309,481, $420,000, and $25,814 and the 
leases expire on May 31, 2003, December 31, 2010 and July 31, 1999, 
respectively.

     The Company has committed to purchase during 1999, additional used 
aircraft and new and used engines for its operations. Certain deposits were 
made in connection with these commitments. The Company's current, remaining 
commitment to such purchases is not more than $31.1 million.

6.   OPERATING SEGMENTS

    The Company operates in two business segments: (i) Leasing and Related 
Operations which involves acquiring and leasing, primarily pursuant to 
operating leases, commercial aircraft, aircraft spare engines and other 
aircraft equipment and the selective purchase and resale of commercial 
aircraft engines and other aircraft equipment and (ii) Spare Parts Sales 
which involves the purchase and resale of after-market engine and airframe 
parts, whole engines, engine modules and rotable aircraft components and 
leasing of engines destined for disassembly and sale of parts.

    In 1998, the Company formed Pacific Gas Turbine Center, Incorporated 
("PGTC") to engage in engine disassembly and maintenance, repair and overhaul 
services. During the three months ended March 31, 1999, the majority of 
PGTC's revenue was derived from services provided to WASI. Revenue from third 
parties during this period was not material. Accordingly, for the three 
months ended March 31, 1999, the operations of PGTC are included in the Spare 
Parts Sales segment. PGTC was not in operation during the three months ended 
March 31, 1998.

                                       8

<PAGE>

    The Company evaluates the performance of each of the segments based on
profit or loss after general and administrative expenses and inter-company
allocation of interest expense. While the Company believes there are synergies
between the two business segments, the segments are managed separately because
each requires different business strategies.

    The following tables present a summary of the operating segments (in
thousands):

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

     OVERVIEW

     The Company's core business is acquiring and leasing, primarily pursuant 
to operating leases, commercial aircraft spare engines, aircraft and other 
aircraft equipment. The Company, through WASI, also specializes in the 
purchase and resale of aftermarket airframe and engine parts, engines, 
modules and rotable components. In July 1998, the Company formed Pacific Gas 
Turbine Center, Incorporated ("PGTC"). PGTC provides engine disassembly and 
maintenance, repair and overhaul services to WASI and third parties from the 
Company's San Diego location. In addition, the Company engages in the 
selective purchase and resale of commercial aircraft engines.

     Revenue consists primarily of lease revenue, income from the sale of 
spare parts and components and income from the sale of engines and equipment.

     RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THE THREE MONTHS ENDED MARCH

</TABLE>

    LEASING RELATED ACTIVITIES. Lease related revenue for the quarter ended 
March 31, 1999, increased 64% to $10.6 million from $6.4 million for the 
comparable period in 1998. This increase reflects lease related revenues from 
additional engines, aircraft and spare parts packages. The aggregate of net 
book value of leased equipment and net investment in direct finance lease at 
March 31, 1999 and 1998 was $289.8 million and $193.8 million, respectively, 
an increase of 50%.

    During the quarter ended March 31, 1999, 6 engines were added to the 
Company's lease portfolio at a total cost of $20.1 million. Eight engines 
from the lease portfolio were sold or transferred to inventory for sale. The 
engines sold from the lease portfolio had a total net book value of $11.2 
million and were sold for a gain of $3.4 million.

    During the quarter ended March 31, 1998, the Company sold one engine from 
the lease portfolio. The engine had a net book value of $2.2 million and was 
sold for a gain of $3.1 million.

    During the quarter ended March 31, 1999, the Company sold two engines 
acquired for resale for $5.8 million which resulted in a gain of $1.0 
million. The Company had no such sales during the comparable 1998 period.

    SPARE PARTS SALES. Revenues from spare parts sales increased 197% to $9.0 
million as compared to $3.0 million in the quarter ended March 31, 1998. The 
gross margin decreased to 26% from 32% in the corresponding period in 1998. 
This decrease was due to a change in the mix of parts being sold during the 
past twelve months.

                                       11

<PAGE>

    INTEREST AND OTHER INCOME.  Interest and other income for the quarters 
ended March 31, 1999 and 1998, were $0.2 million. This is a result of 
interest earned on cash and deposits held.

    INTEREST EXPENSE AND RESIDUAL SHARING Interest expense related to all 
activities increased 88% to $4.9 million for the quarter ended March 31, 
1999, from the comparable period in 1998, due to an increase in average debt 
outstanding during the period. This increase in debt was primarily related to 
debt associated with the increase in lease portfolio assets and to a lesser 
extent an increase in spare parts inventories. Residual sharing expense 
decreased 10% to $211,560 for the quarter ended March 31, 1999 from $232,512 
for the comparable period in 1998. The decline was due to the repayment, in 
March 1998, of one of the Company's loans which had residual sharing 
provisions. Residual sharing arrangements apply to three of the Company's 
engines as of March 31, 1999. The Company accrues for its residual sharing 
obligations using net book value as a proxy for residual proceeds.

    DEPRECIATION EXPENSE. Depreciation expense increased 120% to $3.1 million 
for the quarter ended March 31, 1999, from the comparable period in 1998, due 
primarily to the increase in lease portfolio assets.

    GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses 
increased 47% to $4.7 million for the quarter ended March 31, 1999, from the 
comparable period in 1998. This increase reflects expenses, in all business 
segments, associated with staff additions, increased rent due to the 
expansion of the facilities, as well as an increase in professional fees and 
insurance expense.

     INCOME TAXES. Income taxes, exclusive of tax on extraordinary items, for 
the quarter ended March 31, 1999, increased to $1.9 million from $1.3 million 
for the comparable period in 1998. This increase reflects an increase in the 
Company's pre-tax earnings. The effective tax rate for the quarters ended 
March 31, 1999 and 1998 were 40%.

    EXTRAORDINARY ITEM. In March 1998, the Company repaid a loan that had 
residual sharing provisions and an interest rate of 10%. The repayment 
resulted in an extraordinary expense of $0.2 million, net of tax. The Company 
had no such transactions during the comparable 1999 period.

ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 
133, "Accounting for Derivative Instruments and Hedging Activities", which 
standardizes the accounting for derivative instruments, including certain 
derivative instruments embedded in other contracts, by requiring that an 
entity recognize those items as assets or liabilities in the statement of 
financial position and measure them at fair value. This statement is 
effective for all quarters of fiscal years beginning after June 15, 1999. The 
Company is reviewing the effect this standard will have on the Company's 
consolidated financial statements.

LIQUIDITY AND CAPITAL RESOURCES

     Historically, the Company has financed its growth through borrowings 
secured by its equipment lease portfolio. Cash of approximately $30.9 million 
and $49.4 million, in the three month periods ended March 31, 1999 and 1998, 
respectively, was derived from this activity. In these same time periods 
$20.4 million and $8.0 million, respectively, was used to pay down related 
debt. Cash flow from operating activities used approximately $1.6 million and 
$0.8 million in the three month periods ended March 31, 1999 and 1998, 
respectively. The deficit cash flow from operations was primarily 
attributable to repayment of an account payable related to the purchase of an 
engine and an increase in WASI's accounts receivable due to increased sales.

     The Company's primary use of funds is for the purchase of equipment for 
lease. Approximately $23.0 million and $50.3 million of funds were used for 
this purpose in the three month periods ended March 31, 1999 and 1998, 
respectively.

     At March 31, 1999, the Company had a $150.0 million revolving credit 
facility to finance the acquisition of aircraft engines, aircraft and spare 
parts for sale or lease as well as for general working capital purposes. As 
of March 31, 1999, 

                                       12

<PAGE>

$9.3 million was available under this facility, subject to the Company 
providing sufficient collateral. The facility has a two-year revolving period 
followed by a four-year term-out period. The facility is renewable annually.

     At March 31, 1999, the Company had an $80.0 million debt warehouse 
facility, to a wholly-owned special purpose finance subsidiary of the 
Company, WLFC Funding Corporation, for the financing of jet aircraft engines 
transferred by the Company to such finance subsidiary. This transaction's 
structure facilitates future public or private securitized note issuances by 
the special purpose finance subsidiary. The subsidiary is consolidated for 
financial statement presentation purposes. The facility has an eight-year 
initial term. The Company has guaranteed the obligations under the facility 
on a limited basis, up to an amount equal to the greater of (i) the lesser of 
$5 million and 20% of the outstanding obligations or (ii) 10% of the 
outstanding obligations. Assuming compliance with the facility's terms, 
including sufficiency of collateral, as of March 31, 1999, $15.0 million was 
available under this facility.

      Approximately $10.1 million of the Company's debt is repayable during 
1999. Such repayments consist of scheduled installments due under term loans.

     The Company believes that its current equity base, internally generated 
funds and existing and contemplated debt facilities are sufficient to fund 
the Company's anticipated operations into the third quarter of 1999, at which 
time additional capital will be required to fund projected growth. The 
Company is currently discussing, with its commercial and investment banks, 
additions to its debt and equity capital bases.

      As of March 31, 1999, the Company had two engines and four spare parts 
packages which had not been financed. The Company may seek 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, since the underlying lease revenue is fixed. See 
"Management - Interest Rate Exposure" below.

     The Company has committed to purchase, during 1999, additional used 
aircraft and used and new engines for its operations. Certain deposits were 
made, in 1998, in connection with a portion of these commitments. As of March 
31, 1999, the Company's current commitment to such purchases is not more than 
$31.1 million, which includes $1.4 million of deposits in other assets.

MANAGEMENT OF INTEREST RATE EXPOSURE

    At March 31, 1999, $207.7 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. 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 interest rate that the 
Company pays under its borrowings.

    In September 1996, the Company purchased an amortizing interest rate cap 
in order 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 March 31, 1999, the 
notional principal amount of the cap was $34.3 million, which will decline to 
$26.0 million at the end of its term. The cost of the cap is being amortized 
as an expense over its remaining term. To further mitigate exposure to 
interest rate changes, the Company entered into an interest rate swap 
agreement in December 1998, which has a notional outstanding amount of $15.0 
million, a duration of two years and a fixed rate of 4.95%. Under its 
borrowing agreement, WLFC Funding Corporation is required to hedge a certain 
portion of its $80 million warehouse facility against changes in interest 
rates. WLFC has entered into interest rate swap agreements in order to meet 
such hedging requirements and to manage the variable interest rate risk 
related to its debt. As of March 31, 1999, such swap agreements had notional 
outstanding amounts of $40 million, a weighted average remaining duration of 
36 months and a weighted average fixed rate of 5.88%.

    The Company will be exposed to risk in the event of non-performance of 
the interest rate hedge counter parties. The Company anticipates that it will 
hedge additional amounts of its floating rate debt during the next several 
months.

FACTORS THAT MAY AFFECT FUTURE RESULTS

    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 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-K for the year ended 
December 31, 1998. 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 or in other written or oral statements by the 
Company.

     The businesses in which the Company is engaged are capital intensive 
businesses. Accordingly, the Company's ability to successfully execute its 
business strategy and to sustain its operations is dependent, in large part, 
on the availability of debt and equity capital. There can be no assurance 
that the necessary amount of such capital will continue to be available to 
the Company on favorable terms or at all. If the Company is not successful in 
obtaining sufficient capital, the Company's ability to: (i) add new aircraft 
engines, aircraft and spare parts packages to its portfolio, (ii) add 
inventory to support its spare parts sales, (iii) fund its working capital 
needs, (iv) develop the business of PGTC, and (v) finance possible future 
acquisitions, would be impaired. The Company's inability to obtain sufficient 
capital would have a material adverse effect on the Company's business, 
financial condition and/or results of operations.

     The Company retains title to the aircraft engines, aircraft and parts 
packages that it leases to third parties. Upon termination of a lease, the 
Company will seek to re-lease or sell the aircraft equipment or will 
dismantle the equipment and will sell the parts. The Company also engages in 
the selective purchase and resale of commercial aircraft engines and engine 
components. On occasion, the Company purchases engines or components without 
having a firm commitment for their sale. Numerous factors, many of which are 
beyond the Company's control, may have an impact on the Company's ability to 
re-lease or sell aircraft equipment on a timely basis, including the 
following: (i) general market conditions, (ii) the condition of the aircraft 
equipment upon termination of the lease, (iii) the maintenance services 
performed during the lease term and, as applicable, the number of hours 
remaining until the next major maintenance is required, (iv) regulatory 
changes (particularly those imposing environmental, maintenance and other 
requirements on the operation of aircraft engines), (v) changes in the supply 
or cost of aircraft engines, and (vi) technological developments. There is no 

                                      14

<PAGE>

assurance that the Company will be able to re-lease or sell aircraft 
equipment on a timely basis or on favorable terms. The failure to re-lease or 
sell aircraft equipment on a timely basis or on favorable terms re-lease or 
sell aircraft equipment on a timely basis or on favorable terms could have a 
material adverse effect on the Company's business, financial condition and/or 
results of operations.

     The Company experiences fluctuations in its operating results. Such 
fluctuations may be due to a number of factors, including: (i) general 
economic conditions, (ii) the timing of sales of engines and spare parts, 
(iii) financial difficulties experienced by airlines, (iv) interest rates, 
(v) fuel costs, (vi) downturns in the air transportation industry, (vii) 
increased fare competition, (viii) decreases in growth of air traffic, (ix) 
unanticipated early lease termination or a default by a lessee, (x) the 
timing of engine acquisitions, (xi) engine marketing activities, (xii) 
fluctuations in market prices for the Company's assets. The Company 
anticipates that fluctuations from period to period will continue in the 
future. As a result, the Company believes that comparisons to results of 
operations for preceding periods are not necessarily meaningful and that 
results of prior periods should not be relied upon as an indication of future 
performance.

     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 due 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 and/or results of 
operations. Various airlines have experienced financial difficulties in the 
past, certain airlines have filed for bankruptcy and a number of such 
airlines have ceased operations. In most cases where a debtor seeks 
protection under Chapter 11 of Title 11 of the United States 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 aircraft equipment. The scope of Section 1110 
has been the subject of significant litigation and there is no assurance that 
the provisions of Section 1110 will protect the Company's investment in an 
aircraft, aircraft engines or parts 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. Leases of spare parts may involve additional risks. For example, 
it is likely to be more difficult to recover parts in the event of a lessee 
default and the residual value of parts may be less ascertainable than an 
engine.

    The Company's leases are generally structured at fixed rental rates for 
specified terms while many of the Company's borrowings are at a floating 
rate. 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 interest rate the Company pays under its borrowings, 
and have a material adverse effect on the Company's business, financial 
condition and/or results of operations.

    During the three month period ended March 31, 1999, 76% of the Company's 
lease revenue was generated by leases to foreign customers, including 7% from 
Asian customers and 18% from South American customers. Such international 
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. 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 addition, political 
instability abroad and changes in international policy also present risk of 
expropriation of the Company's leased engines. Furthermore, many foreign 
countries have currency and exchange laws regulating the international 
transfer of currencies.

    The Company generates a portion of its revenue from sale of leased 
assets. The inability to execute transactions for gain on sale or a change in 
the accounting guidelines related to such sales could have a material impact 
on the Company's business, financial condition and/or results of operations.

    The Company has recently experienced significant growth in revenues. The 
Company's growth has placed, and is expected to continue to place, a 
significant strain on the Company's managerial, operational and financial 
resources. There is 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, 
in which event the Company's business, financial condition and/or results of 
operations could be adversely affected. The Company may also acquire 
businesses that would complement or expand the Company's existing businesses. 
Any acquisition or expansion made by the Company may result in one or more of 
the following events: (i) the incurrence of additional debt, (ii) future 

                                      15

<PAGE>

charges to earnings related to the amortization of goodwill and other 
intangible assets, (iii) difficulties in the assimilation of operations, 
services, products and personnel, (iv) an inability to sustain or improve 
historical revenue levels, (v) diversion of management's attention from 
ongoing business operations, and (vi) potential loss of key employees. Any of 
the foregoing factors could have a material adverse effect on the Company's 
business, financial condition and/or results of operations.

    The markets for the Company's products and services are extremely 
competitive, and the Company faces competition from a number of sources. 
These include aircraft and aircraft part manufacturers, aircraft and aircraft 
engine lessors, airline and aircraft service companies and aircraft spare 
parts redistributors. Certain of the Company's competitors have substantially 
greater resources than the Company, including greater name recognition, 
larger inventories, a broader range of material, complementary lines of 
business and greater financial, marketing and other resources. In addition, 
equipment manufacturers, aircraft maintenance providers, FAA certified repair 
facilities and other aviation aftermarket suppliers may vertically integrate 
into the markets that the Company serves, thereby significantly increasing 
industry competition. There can be no assurance that competitive pressures 
will not materially and adversely affect the Company's business, financial 
condition and/or results of operations.

     The Company's leasing activities generate significant depreciation 
allowances that provide the Company with substantial tax benefits on an 
ongoing basis. In addition, the Company's lessees currently enjoy favorable 
accounting and tax treatment by entering into operating leases. Any change to 
current tax laws or accounting principles that make operating lease financing 
less attractive or affect the Company's recognition of revenue or expense 
would have a material impact on the Company's business, financial condition 
and/or results of operations.

     Before parts may be installed in an aircraft, they must meet certain 
standards of condition established by the FAA and/or the equivalent 
regulatory agencies in other countries. Specific regulations vary from 
country to country, although regulatory requirements in other countries are 
generally satisfied by compliance with FAA requirements. Parts must also be 
traceable to sources deemed acceptable by the FAA or such equivalent 
regulatory agencies. Such standards may change in the future, requiring 
engine components already contained in the Company's inventory to be scrapped 
or modified. In all such cases, to the extent the Company has such engine 
components in its inventory, their value may be reduced and the Company's 
business, financial condition and/or results of operations could be adversely 
affected

     The Company obtains a substantial portion of its inventories of 
aircraft, engines and engine parts from airlines, overhaul facilities and 
other suppliers. There is no organized market for aircraft, engines and 
engine parts, and the Company must rely on field representatives and 
personnel, advertisements and its reputation as a buyer of surplus inventory 
in order to generate opportunities to purchase such equipment. The market for 
bulk sales of surplus aircraft, engines and engine parts is highly 
competitive, in some instances involving a bidding process. While the Company 
has been able to purchase surplus inventory in this manner successfully in 
the past, there is no assurance that surplus aircraft, engines and engine 
parts of the type required by the Company's customers will be available on 
acceptable terms when needed in the future or that the Company will continue 
to compete effectively in the purchase of such surplus equipment.

     A change in the market for aircraft and engine parts could result in the 
Company's inventory being overvalued and could require the Company to 
write-down its inventory valuations in order to bring them into line with the 
revised fair market value. Furthermore, when the Company purchases and 
dismantles used aircraft, engines and parts, the Company assigns a value to 
the parts based on market price. Airline manufacturers may also develop new 
parts to be used in lieu of parts already contained in the Company's 
inventory. There is no assurance that a write-down would not adversely affect 
the Company's business, operating results or financial condition.

     The Company uses computer systems in many areas of its operations. In 
addition, various third parties that are important to the Company's business 
(including lessees, customers, vendors and financial institutions) use 
computer systems in their areas of operations. Should the Company or certain 
of such third parties not be "Year 2000 compliant," certain of the Company's 
operations could be disrupted for an indeterminate period of time, 
potentially having a material adverse impact on the Company's results, 
business, financial condition and/or of operations. As is the case with most 
companies, the Year 2000 computer problem creates risks for the Company.

                                      16

<PAGE>

     The Company has assessed the Year 2000 computer problem as it affects 
the Company's computer systems and information technology. As a result of the 
Company's assessment, the Company does not expect any material interruption 
of internal operations arising from the Company's computer systems and 
information technology not being Year 2000 compliant. The mission critical 
systems of the Company identified during the assessment are all off the shelf 
software packages with unmodified source codes which have been certified by 
the manufacturer as Year 2000 compliant. The Company is not aware of any 
significant Year 2000 issues with respect to the airworthiness of the 
Company's aircraft, aircraft engines or spare parts; however, should such 
issues result in Airworthiness Directives or other manufacturer recommended 
maintenance for leased assets, the implementation and the majority of the 
cost of such implementation would generally be the responsibility of the 
lessee. Any resulting costs to the Company cannot be estimated at this time.

     Significant uncertainties remain about the effect on the Company's 
operations of third parties that may not be Year 2000 compliant and with whom 
the Company does business (including lessees, customers, vendors and 
financial institutions). The Company is in the process of assessing Year 2000 
issues relating to such third parties and certain of the Company's officers 
have oversight of these assessments. The Company has circulated to 
significant third parties with whom the Company does business a written 
request for their plans and progress in addressing the Year 2000 issue. The 
Company intends to evaluate the responses and develop contingency plans to 
address risks of non-compliance by such third parties. The Company expects to 
complete this process by July 1999. The costs associated with assessing the 
Year 2000 issue, including developing and implementing the above plan, are 
expected to be nominal. Non-compliance on the part of a third party could 
result in lost revenue and an inability to make lease or other payments to 
the Company. Non-compliance by the third party's financial institution could 
also affect the ability to process payments.

     A reasonable worst case scenario would be that a large number of third 
parties (including lessees and spare parts customers) will be unable to 
operate and generate revenues and as a result will be unable to make lease 
payments or purchase parts. The Company is unable to estimate the likelihood 
or the magnitude of the resulting lost revenue at this time. However, should 
this occur, the Company would attempt to repossess leased engines, aircraft 
and spare parts from non-compliant third parties and place such assets with 
compliant third parties. The Company cannot assure you that it would be able 
to re-lease such assets at favorable terms or at all. Similarly, the Company 
would attempt to find compliant customers for the Company's spare parts 
sales. If a significant number of leased assets could not be re-leased on 
favorable terms or at all, or their re-lease is delayed, or if compliant 
customers for spare parts sales were unavailable, the Company's business, 
financial condition and/or results of operations would be adversely affected.

     Providers of casualty and liability insurance to the aviation industry 
have indicated that they may exclude coverage for Year 2000 related risks 
and/or may require aviation equipment operators to answer, to the insurance 
provider's satisfaction, a questionnaire regarding the Year 2000 preparedness 
of aviation equipment operators, in order to provide coverage for Year 2000 
risks. The inability of a lessee to obtain or maintain coverage for Year 2000 
related losses and/or the Company's inability to obtain or maintain any 
contingent insurance for Year 2000 related risks would expose the Company to 
material risk of loss. The Company is in the process of informing its lessees 
of Year 2000 related insurance issues and will be monitoring its lessees' 
ability to obtain insurance coverage for Year 2000 related risks.

ITEM 2A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company's primary market risk exposure is that of interest rate 
risk. A change in the U.S. prime interest rate, LIBOR rate, or cost of funds 
based on commercial paper market rates, would affect the rate at which the 
Company could borrow funds under its various borrowing facilities. Increases 
in interest rates to the Company, which may cause the Company to raise the 
implicit rates charged to its customers, could result in a reduction in 
demand for the Company's leases. Certain of the Company's warehouse credit 
facilities are variable rate debt. The Company estimates a one percent 
increase or decrease in the Company's variable rate debt would result in an 
increase or decrease, respectively, in interest expense of $1.4 million per 
annum. The Company estimates a two percent increase or decrease in the 
Company's variable rate debt would result in an increase or decrease, 
respectively, in interest expense of $2.9 million per annum. The foregoing 
effect of interest rate changes, net of interest rate hedges, on per annum 
interest expense is estimated as constant due to the terms of the Company's 
variable rate borrowings, which generally provide for the maintenance of 
borrowing levels given adequacy of collateral and compliance with other loan 
conditions.

                                       17

<PAGE>

     The Company hedges a portion of its borrowings, effectively fixing the 
rate of these borrowings. The Company is currently required to hedge a 
portion of debt of the WLFC Funding Corporation Facility. Such hedging 
activities may limit the Company's ability to participate in the benefits of 
any decrease in interest rates, but may also protect the Company from 
increases in interest rates. A portion of the Company's leases provide that 
lease payments be adjusted based on changes in interest rates. Furthermore, 
since lease rates tend to vary with interest rate levels, it is likely that 
the Company can adjust lease rates for the effect of change in interest rates 
at the termination of leases. Other financial assets and liabilities are at 
fixed rates.

     The Company is also exposed to currency devaluation risk. During the 
three month period ended March 31, 1999, 76% of the Company's total lease 
revenues came from non-United States domiciled lessees. All of the leases 
require payment in United States (U.S.) currency. If these lessees' currency 
devalues against the U.S. dollar, the lessees could potentially encounter 
difficulty in making the U.S. dollar denominated lease payments.

     SECTION 2.1    SALE AND DELIVERY OF THE CLASS A NOTE.

     On the basis of the representations and warranties and subject to the 
terms and conditions herein set forth, the Issuer agrees to deliver to the 
Deal Agent on behalf of the Purchasers, on the Closing Date, the Class A Note 
with a maximum principal amount of $80,000,000, which Class A Note shall be

     SECTION 2.2    ACCEPTANCE AND CUSTODY OF SERIES 1997-1 CLASS A NOTES.  

     On the Closing Date, the Deal Agent shall take delivery of the Class A

     SECTION 2.3    FUNDINGS OF LOANS.

     (a)   On the terms and conditions hereinafter set forth, the Issuer may, 
at its option, request Loans from the Purchasers.  The Deal Agent may act on 
behalf of and for the benefit of the Purchasers in this regard.  VFCC may, in 
its sole discretion, fund, or if VFCC shall decline to fund, the Liquidity 
Agent shall fund on behalf of the Investors, Loans from time to time during 
the period from the date hereof to but not including the Termination Date.  
Under no circumstances shall any Purchaser fund any Loan if, after giving 
effect to such Funding or Incremental Funding, the aggregate Class A Note 
Principal Balance outstanding hereunder would exceed the lesser of (i) the 
Class A Note Commitment or (ii) the Asset Base.

     (b)   The Issuer may, within 60 days, but no later than 45 days, prior 
to the then existing Commitment Termination Date, by written notice to the 
Deal Agent, make written request for VFCC and the Investors to extend the 
Commitment Termination Date for an additional period of 364 days.  The Deal 
Agent will give prompt notice to VFCC and each of the Investors of its 
receipt of such request for extension of the Commitment Termination Date.  
VFCC and each Investor shall make a determination, in their sole discretion 
and after a full credit review, not less than 15 days prior to the then 
applicable Commitment Termination Date as to 

                                      4
<PAGE>

whether or not it will agree to extend the Commitment Termination Date; 
PROVIDED, HOWEVER, that the failure of VFCC or any Investor to make a timely 
response to the Issuer's request for extension of the Commitment Termination 
Date shall be deemed to constitute a refusal by VFCC or the Investor, as the 
case may be, to extend the Commitment Termination Date.  The Commitment 
Termination Date shall only be extended upon the consent of both (i) VFCC and 
(ii) 100% of the Investors.

     SECTION 2.4    THE INITIAL FUNDING, SUBSEQUENT FUNDINGS AND INCREMENTAL 
                    FUNDINGS.

     (a)   Subject to the conditions described in Section 2.3, the initial 
Funding and each Incremental Funding shall be made in accordance with the 
procedures described in Section 2.4(b).

     (b)   The initial Funding and each Incremental Funding shall be made, 
after receipt by the Purchasers of a Loan Request delivered by the Issuer to 
the Deal Agent at least two Business Days prior to such proposed Funding Date 
and each such notice shall specify (i) the aggregate amount of such initial 
Funding or Incremental Funding which amount must satisfy the applicable 
minimum requirement set forth in the following sentence and (ii) the date of 
such Funding or Incremental Funding.  The Issuer shall deliver no more than 
two such notices in any calendar month, and each amount specified in any such 
notice must satisfy the following minimum requirements, as applicable, as a 
condition to the related Funding: (i) the initial Funding shall be in an 
amount equal to $5,000,000 or an integral multiple of $10,000 in excess 
thereof; (ii)  each Incremental Funding hereunder  shall be in an amount 
equal to $1,000,000 or an integral multiple of $10,000 in excess thereof; 
PROVIDED, HOWEVER, that if such Incremental Funding is to be made hereunder 
at a time when there is no outstanding Commercial Paper issued in respect of 
a Funding of $5,000,000 or an integral multiple of $10,000 in excess thereof, 
then such Incremental Funding shall be in an amount equal to $5,000,000 or an 
integral multiple of $10,000 in excess thereof.  Each notice delivered by the 
Issuer pursuant to this Section 2.4 shall be irrevocable.  Following receipt 
of such notice, the Deal Agent will consult with VFCC in order to assist VFCC 
in determining whether or not to make the purchase.  If VFCC declines to make 
a proposed purchase, the initial Funding or Incremental Funding will be made 
by the Investors.  On the date of such Funding or Incremental Funding, as the 
case may be, VFCC or each Investor shall, upon satisfaction of the applicable 
conditions set forth in Article III, make available to the Issuer in same day 
funds, at such bank or other location reasonably designated by Issuer in its 
Loan Request given pursuant to this Section 2.4(b), an amount equal to (i) 
the amount of such Loan related to such initial Funding or Incremental 
Funding, as the case may be, in the case of a Funding by VFCC or (ii) such 
Investor's pro rata share of the amount of such Loan, in the case of a 
purchase by the Investors.

     SECTION 2.5    REDUCTION OF THE CLASS A NOTE COMMITMENT.

     The Issuer may, upon at least five Business Days' notice to the Deal 
Agent, terminate in whole or reduce in part the portion of the Class A Note 
Commitment that exceeds the sum of the aggregate Class A Note Principal 
Balance and interest accrued and to accrue thereon through the date of 
payment, and the Commitments of the Purchasers shall be reduced 
proportionately; 

                                      5
<PAGE>

PROVIDED, HOWEVER, that each partial reduction of the Class A Note Commitment 
shall be in an aggregate amount equal to $1,000,000 or an integral multiple 
thereof.  Each notice of reduction or termination pursuant to this Section 
2.5 shall be irrevocable.

     SECTION 2.6    DETERMINATION OF INTEREST.  

     The Deal Agent shall determine the Interest (including unpaid Interest, 
if any, due and payable on a prior Payment Date) to be paid on each Payment 
Date for the applicable Interest Accrual Period and shall advise the Issuer 
and the Indenture Trustee thereof on the related Determination Date.

     SECTION 2.7    PAYMENTS, COMPUTATIONS, ETC.

     (a)   Unless otherwise expressly provided herein, all amounts to be paid 
or deposited by the Issuer or the Servicer hereunder shall be paid or 
deposited in accordance with the terms hereof no later than 11:00 A.M. 
(Charlotte, North Carolina time) on the day when due in lawful money of the 
United States in immediately available funds to the Agent's Account.  The 
Issuer shall, to the extent permitted by law, pay to the Purchasers interest 
on all amounts not paid or deposited when due hereunder at 1% per annum above 
the Base Rate, payable on demand; PROVIDED, HOWEVER, that such interest rate 
shall not at any time exceed the maximum rate permitted by applicable law.  
Such interest shall be retained by the Deal Agent except to the extent that 
such failure to make a timely payment or deposit has continued beyond the 
date for distribution by the Deal Agent of such overdue amount to the 
Purchasers, in which case such interest accruing after such date shall be for 
the account of, and distributed by the Deal Agent to the Purchasers.  All 
computations of interest and other fees hereunder shall be made on the basis 
of a year of 360 days for the actual number of days (including the first but 
excluding the last day) elapsed.

     (b)   Whenever any payment hereunder shall be stated to be due on a day 
other than a Business Day, such payment shall be made on the next succeeding 
Business Day, and such extension of time shall in such case be included in 
the computation of payment of Interest or any fee payable hereunder, as the 
case may be.

     (c)   If any Funding or Incremental Funding requested by the Issuer and 
approved by a Purchaser and the Deal Agent pursuant to Section 2.4, is not, 
for any reason whatsoever related to a default or nonperformance by the 
Issuer, made or effectuated, as the case may be, on the date specified 
therefor, the Issuer shall indemnify such Purchaser against any reasonable 
loss, cost or expense incurred by such Purchaser, including, without 
limitation, any loss (excluding loss of anticipated profits, net of 
anticipated profits in the reemployment of such funds in the manner 
determined by such Purchaser), cost or expense incurred by reason of the 
liquidation or reemployment of deposits or other funds acquired by such 
Purchaser to fund or maintain such Funding or Incremental Funding, as the 
case may be, during such Interest Accrual Period.

<PAGE>

     SECTION 2.8    INCREASED COSTS; CAPITAL ADEQUACY; ILLEGALITY.

     (a)   If either (i) the introduction of or any change (including, 
without limitation, any change by way of imposition or increase of reserve 
requirements) in or in the interpretation of any law or regulation after the 
date of this Agreement or (ii) the compliance by a Purchaser or any Affiliate 
thereof (each of which, an "Affected Party") with any guideline or request 
from any central bank or other governmental agency or authority (whether or 
not having the force of law), (A) shall subject an Affected Party to any Tax 
(except for Taxes on the overall net income of such Affected Party), duty or 
other charge with respect to an Asset Interest, a Loan, or a Funding or any 
right to make Fundings hereunder, or on any payment made hereunder or under 
the Supplement or (B) shall impose, modify or deem applicable any reserve 
requirement (including, without limitation, any reserve requirement imposed 
by the Federal Reserve Board, but excluding any reserve requirement, if any, 
included in the determination of Interest), special deposit or similar 
requirement against assets of, deposits with or for the amount of, or credit 
extended by, any Affected Party or (C) shall impose any other condition 
affecting an Asset Interest, a Loan or a Purchaser's rights hereunder, the 
result of which is to increase the cost to any Affected Party or to reduce 
the amount of any sum received or receivable by an Affected Party under this 
Agreement or the Supplement (any such costs being referred to herein as 
"Increased Costs"), then within ten days after demand by such Affected Party 
(which demand shall be accompanied by a statement setting forth the basis for 
such demand), the Issuer shall pay directly to such Affected Party such 
additional amount or amounts as will compensate such Affected Party for such 
additional or increased cost incurred or such reduction suffered.

     (b)   If either (i) the introduction of or any change in or in the 
interpretation of any law, guideline, rule, regulation, directive or request 
after the date of this Agreement or (ii) compliance by any Affected Party 
with any law, guideline, rule, regulation, directive or request from any 
central bank or other governmental authority or agency (whether or not having 
the force of law), including, without limitation, compliance by an Affected 
Party with any request or directive regarding capital adequacy, has or would 
have the effect of reducing the rate of return on the capital of any Affected 
Party as a consequence of its obligations hereunder or arising in connection 
herewith to a level below that which any such Affected Party could have 
achieved but for such introduction, change or compliance (taking into 
consideration the policies of such Affected Party with respect to capital 
adequacy) by an amount deemed by such Affected Party to be material, then 
from time to time, within ten days after demand by such Affected Party (which 
demand shall be accompanied by a statement setting forth the basis for such 
demand), the Issuer shall pay directly to such Affected Party such additional 
amount or amounts as will compensate such Affected Party for such reduction.

     (c)   If as a result of any event or circumstance similar to those 
described in clauses (a) or (b) of this Section 2.8, any Affected Party is 
required to compensate a bank or other financial institution providing 
liquidity support, credit enhancement or other similar support to such 
Affected Party in connection with this Agreement or the funding or 
maintenance of Fundings hereunder, then within ten days after demand by such 
Affected Party, the Issuer shall pay to such Affected Party such additional

     (d)   In determining any amount provided for in this Section 2.8, the 
Affected Party may use any reasonable averaging and attribution methods.  Any 
Affected Party making a claim under this section shall submit to the Issuer a 
certificate setting forth in reasonable detail as to such additional or 
increased cost or reduction, which certificate shall be conclusive absent 
demonstrable error.

     (e)   If a Purchaser shall notify the Deal Agent that a Eurodollar 
Disruption Event as described in clause (a) of the definition of "Eurodollar 
Disruption Event" has occurred, the Deal Agent shall in turn so notify the 
Issuer, whereupon all Loans in respect of which Interest accrues at the 
Adjusted Eurodollar Rate shall immediately be converted into Loans in respect 
of which Interest accrues at the Base Rate.

     SECTION 2.9    TAXES.

     (a)   All payments made by a Lessee in respect of a Lease Agreement and 
all payments made by the Issuer or the Servicer under this Agreement or the 
Supplement will be made free and clear of and without deduction or 
withholding for or on account of any Taxes, unless such withholding or 
deduction is required by law.  In such event, the Lessee, Issuer, or Servicer 
(as the case may be) shall pay to the appropriate taxing authority any such 
Taxes required to be deducted or withheld (subject to compliance by each 
Purchaser with Section 2.9(d)) and the amount payable to each Purchaser or 
the Deal Agent (as the case may be) will be increased (such increase, the 
"Additional Amount") such that every net payment made under this Agreement 
after deduction or withholding for or on account of any Taxes (including, 
without limitation, any Taxes on such increase) is not less than the amount 
that would have been paid had no such deduction or withholding been deducted 
or withheld.  The foregoing obligation to pay Additional Amounts, however, 
will not apply with respect to net income or franchise taxes imposed on a 
Purchaser or the Deal Agent, respectively, with respect to payments required 
to be made by the Issuer or Servicer under this Agreement, by a taxing 
jurisdiction in which such Purchaser or Deal Agent is organized, conducts 
business or is paying taxes as of the date such tax obligation is incurred 
(as the case may be).  If a Purchaser or the Deal Agent pays any Taxes in 
respect of which the Issuer is obligated to pay Additional Amounts under this 
Section 2.9(a), the Issuer shall promptly reimburse such Purchaser or Deal 
Agent in full.

     (b)   The Issuer will indemnify each Purchaser and the Deal Agent for 
the full amount of Taxes in respect of which the Issuer is required to pay 
Additional Amounts (including, without limitation, any Taxes imposed by any 
jurisdiction on such Additional Amounts) paid by such Purchaser or the Deal 
Agent (as the case may be) and any liability (including penalties, interest 
and expenses) arising therefrom or with respect thereto; PROVIDED, HOWEVER, 
that such Purchaser or the Deal Agent, as appropriate, making a demand for 
indemnity payment shall provide the Issuer, at its address set forth under 
its name on the signature pages hereof, with a certificate from the relevant 
taxing authority or from a responsible officer of such Purchaser or the Deal 
Agent stating or otherwise evidencing that response such Purchaser or the 
Deal Agent has made payment of such Taxes and will provide a copy of or 
extract from documentation, if available, furnished by such taxing authority 
evidencing assertion or payment of such Taxes. 

                                      8
<PAGE>

This indemnification shall be made within ten days from the date a Purchaser 
or the Deal Agent (as the case may be) makes written demand therefor.

     (c)   Within 30 days after the date of any payment by the Issuer of any 
Taxes, the Issuer will furnish to the Deal Agent, at its address set forth 
under its name on the signature pages hereof, appropriate evidence of payment 
thereof.

     (d)   If a Purchaser is not created or organized under the laws of the 
United States or a political subdivision thereof, such Purchaser shall, to 
the extent that it may then do so under applicable laws and regulations, 
deliver to the Issuer with a copy to the Deal Agent (i) within 15 days after 
the date hereof, or, if later, the date on which such Purchaser becomes a 
Purchaser hereof two (or such other number as may from time to time be 
prescribed by applicable laws or regulations) duly completed copies of IRS 
Form 4224 or Form 1001 (or any successor forms or other certificates or 
statements which may be required from time to time by the relevant United 
States taxing authorities or applicable laws or regulations), as appropriate, 
to permit the Issuer to make payments hereunder for the account of such 
Purchaser, as the case may be, without deduction or withholding of United 
States federal income or similar Taxes and (ii) upon the obsolescence of or 
after the occurrence of any event requiring a change in, any form or 
certificate previously delivered pursuant to this Section 2.9(d), copies (in 
such numbers as may from time to time be prescribed by applicable laws or 
regulations) of such additional, amended or successor forms, certificates or 
statements as may be required under applicable laws or regulations to permit 
the Issuer to make payments hereunder for the account of such Purchaser, 
without deduction or withholding of United States federal income or similar 
Taxes.

     (e)   For any period with respect to which a Purchaser or the Deal Agent 
has failed to provide the Issuer with the appropriate form, certificate or 
statement described in Section 2.9(d) (other than if such failure is due to a 
change in law occurring after the date of this Agreement), the Deal Agent or 
such Purchaser, as the case may be, shall not be entitled to indemnification 
under clauses (a) or (b) of this Section 2.9 with respect to any Taxes.

     (f)   Within 30 days of the written request of the Issuer therefor, the 
Deal Agent and the Purchasers, as appropriate, shall execute and deliver to 
the Issuer such certificates, forms or other documents which can be furnished 
consistent with the facts and which are reasonably necessary to assist the 
Issuer in applying for refunds of Taxes remitted hereunder; PROVIDED, 
HOWEVER, that the Deal Agent and the Purchasers shall not be required to 
deliver such certificates forms or other documents if in their respective 
sole discretion it is determined that the deliverance of such certificate, 
form or other document would have a material adverse effect on the Deal Agent 
or Purchasers and PROVIDED FURTHER, HOWEVER, that the Issuer shall reimburse 
the Deal Agent or Purchaser for any reasonable expenses incurred in the 
delivery of such certificate, form or other document.

     (g)   If, in connection with an agreement or other document providing 
liquidity support, credit enhancement or other similar support to the 
Purchasers in connection with this Agreement or the funding or maintenance of 
Fundings hereunder, the Purchasers are required to compensate a bank or other 
financial institution in respect of Taxes under circumstances similar 

                                      9
<PAGE>

to those described in this section then within ten days after demand by the 
Purchasers, the Issuer shall pay to the Purchasers such additional amount or 
amounts as may be necessary to reimburse the Purchasers for any amounts paid 
by them.

     (h)   Without prejudice to the survival of any other agreement of the 
Issuer hereunder, the agreements and obligations of the Issuer contained in 
this Section 2.9 shall survive the termination of this Agreement.

     SECTION 2.10   ASSIGNMENT OF THE CONTRIBUTION AND SALE AGREEMENT.

     The Issuer hereby grants, assigns and pledges to the Deal Agent, for the 
ratable benefit of the Purchasers hereunder, all of the Issuer's right, and 
title to and interest in the Contribution and Sale Agreement.  The Issuer 
confirms that following an Event of Default the Deal Agent shall have the 
sole right to enforce the Issuer's rights and remedies under the Contribution 
and Sale Agreement for the benefit of the Purchasers, but without any 
obligation on the part of the Deal Agent, the Purchasers or any of their 
respective Affiliates, to perform any of the obligations of the Issuer under 
the Contribution and Sale Agreement.  The Issuer further confirms and agrees 
that such assignment to the Deal Agent shall terminate upon the Collection 
Date; PROVIDED, HOWEVER, that the rights of the Deal Agent and the Purchasers 
pursuant to such assignment with respect to rights and remedies in connection 
with any indemnities and any breach of any representation, warranty or 
covenants made by the Seller pursuant to the Contribution and Sale Agreement, 
which rights and remedies survive the termination of the Contribution and 
Sale Agreement, shall be continuing and shall survive any termination of such 
assignment.

                         REPRESENTATIONS AND WARRANTIES

     SECTION 4.1    REPRESENTATIONS AND WARRANTIES OF THE ISSUER.

     The Issuer represents (as of the Effective Date and as of each date on 
which a Loan is made by a Class A Noteholder pursuant to the Supplement, 
unless otherwise indicated) and warrants to, and agrees with, the Purchaser 
that:

           (i)      The Issuer is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware, with its chief 
executive office located at 2320 Marinship Way, Suite 300, Sausalito, 
California 94965, and has the power to own its assets and to engage in the 
activities in which it is presently engaged and is duly qualified and in good 
standing under the laws of each jurisdiction where its ownership of property 
or the conduct of its activities requires such qualification, if the failure 
to so qualify would have a material adverse effect on the financial condition 
of the Issuer or on the enforceability of the Class A Note or the ability of 
the Issuer to perform its obligations under this Agreement and the other 
Related Documents to which it is a party.  One hundred percent of the 
beneficial ownership of the Issuer is owned by Willis Lease Finance 
Corporation ("WLFC").  The Issuer has no subsidiaries;

           (ii)     The Issuer has the power, authority and legal right to 
execute, deliver and perform its obligations under this Agreement and the 
other Related Documents to which it is a party (collectively, the "Issuer 
Documents"); the execution, delivery, and performance of the Issuer Documents 
by the Issuer have been duly authorized by the Issuer by all necessary 
action, the Issuer Documents, other than the Class A Note, have been duly 
executed and delivered by the Issuer, and the Class A Note, when issued in 
accordance with the terms hereof and of the Indenture and the Supplement, 
will have been duly executed and delivered;

           (iii)    Each of the Issuer Documents (other than the Class A 
Note), assuming due authorization, execution and delivery by the other 
parties thereto, constitutes, and the Class A Note, when issued and 
authenticated in accordance with the terms of the Indenture and the 
Supplement, will constitute, a legal, valid and binding obligation of the 
Issuer, enforceable against the Issuer in accordance with its terms, except 
that such enforcement may be limited by (A) bankruptcy, insolvency, 
reorganization, moratorium or other similar laws (whether statutory, 
regulatory or decisional) now or hereafter in effect relating to creditors' 
rights generally and (B) general principles of equity (regardless of whether 
such enforceability is considered in a proceeding in equity or at law);

           (iv)     The consummation of the transactions contemplated by the 
Issuer Documents and the fulfillment of the terms therein will not conflict 
with or result in any breach of any of the terms and provisions of or 
constitute (with or without notice, lapse of time or both) a default under 
the certificate of incorporation or by-laws of the Issuer, or any indenture, 
agreement, mortgage, deed of trust, commitment letter or funding arrangement 
with any lending institution or investment bank or other instrument to which 
the Issuer is a party or by which it is 

                                      12
<PAGE>

bound, or result in the creation or imposition of any lien, claim or 
encumbrance upon any of its properties pursuant to the terms of such 
indenture, agreement, mortgage, deed of trust, commitment letter or funding 
arrangement with any lending institution or investment bank or other such 
instrument, other than as created pursuant to the Indenture and the 
Supplement, or violate any law or, any order, rule or regulation applicable 
to the Issuer of any court or of any federal or state regulatory body, 
administrative agency or other governmental instrumentality having 
jurisdiction over the Issuer or any of its properties and there are no legal 
or governmental proceedings pending or, to the best knowledge of the Issuer, 
threatened or contemplated that would result in a material modification or 
revocation thereof;

           (v)      There are no litigation, proceedings or investigations to 
which the Issuer, or any Affiliate of the Issuer, is a party pending, or, to 
the knowledge of Issuer, threatened, before any court, regulatory body, 
administrative agency or other tribunal or governmental instrumentality (A) 
asserting the invalidity of the Class A Note or the other Issuer Documents, 
(B) seeking to prevent the issuance of the Class A Note or the consummation 
of any of the transactions contemplated by the other Issuer Documents, or (C) 
seeking any determination or ruling that would materially and adversely 
affect the performance by the Issuer of its obligations under, or the 
validity or enforceability of, the Class A Note or the other Issuer Documents;

           (vi)     All approvals, authorizations, consents, orders or other 
actions of any person, corporation or other organization, or of any court,

prior to the Effective Date;

           (vii)    No written materials delivered to the Purchaser by or on 
behalf of the Issuer in connection with the sale of the Class A Note contain 
any untrue statement of a material fact or omit a material fact necessary to 
make the statements contained therein or herein not misleading.  There is no 
fact peculiar to the Issuer or any Affiliate of the Issuer or, to the 
knowledge of the Issuer, any Lease Agreement, Lessee or Engine which the 
Issuer has not disclosed to the Deal Agent in writing which materially 
adversely affects or, so far as the Issuer can now reasonably foresee, will 
materially adversely affect the ability of the Issuer to perform the 
transactions contemplated hereby and by the other Related Documents;

           (viii)   The List of Engines to be created as of the Closing Date 
and each supplement thereto will be available to the Deal Agent by the Issuer

all material respects) description of the Engines;

           (ix)     The representations and warranties made by the Issuer in 
the Issuer Documents are true and correct in all material respects and the 
Purchaser shall be entitled to rely on such representations and warranties;

           (x)      Any taxes, fees and other governmental charges payable by 
the Issuer in connection with the execution and delivery of the Issuer 
Documents, the pledge of the Collateral 

                                      13
<PAGE>

to the Indenture Trustee, and the execution, delivery and sale of the Class A 
Note, have been paid;

           (xi)     To the extent the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), may be deemed to apply to the Class A Note and 
the Loans, none of the transactions contemplated in the Issuer Documents 
(including, without limitation thereof, the use of the proceeds from the sale 
of the Class A Note) will violate or result in a violation of Section 7 of 
the Exchange Act, or any regulations issued pursuant thereto;

           (xii)    Concurrently with the execution and delivery of this 
Agreement, the Issuer is executing no other note purchase agreement with 
respect to the Class A Note;

           (xiii)   The Issuer is not an "investment company" within the 
meaning of the Investment Company Act of 1940, as amended;

           (xiv)    For so long as the Series 1997-1 Class A Notes are the 
only Notes outstanding under the Indenture, each of the Indenture and the 
Supplement need not be qualified as an "indenture" pursuant to the terms of 
the Trust Indenture Act of 1939, as amended;

           (xv)     The Issuer has not taken and will not take, directly or 
indirectly, any action prohibited by Rules 101 and 102 under Regulation M of 
the Securities and Exchange Commission in connection with the offering of the 
Class A Note;

           (xvi)    To the extent that the Securities Act may be deemed to 
apply to the Class A Note and the Loans, neither the Issuer nor any affiliate 
(as defined in Rule 501(b) of Regulation D under the Securities Act 
("Regulation D")) of the Issuer has directly, or through any agent, 
including, without limitation, FUNB, (i) sold, offered for sale, solicited 
offers to buy or otherwise negotiated in respect of, any security (as defined 
in the Securities Act) which is or will be integrated with the sale of the 
Class A Note in a manner that would render the issuance and sale of the Class 
A Note a violation of the Securities Act or require the registration of the 
Class A Note under the Securities Act or (ii) engaged in any form of general 
solicitation or general advertising (within the meaning of Regulation D) in 
connection with the offering of the Class A Note.

           (xvii)   To the extent that the Securities Act may be deemed to 
apply to the Class A Note and the Loans, it is not necessary in connection 
with the offer, sale and delivery of the Class A Note in the manner 
contemplated by this Agreement to register the Class A Note under the 
Securities Act assuming that the Purchaser is an "accredited investor" as 
defined in Regulation D under the Securities Act;

           (xviii)  No event has occurred and is continuing that constitutes, 
or with the passage of time or the giving of notice or both would constitute, 
an Early Amortization Event under, and as defined in, the Indenture.  The 
Issuer is not in violation of any agreement, charter instrument, by-law or 
other instrument to which they are a party or by which they are or may be 
bound;

                                      14
<PAGE>

           (xix)    The aggregate amount of Scheduled Payments payable by the 
Lessees under the Lease Agreements during each Collection Period is 
sufficient to pay the monthly Servicing Fee, and the principal and interest 
on the Class A Note, as such payments become due and payable, in accordance 
with the Indenture and the Supplement;

           (xx)     The Issuer agrees that it will not directly or 
indirectly, sell or offer to sell the Class A Note or similar security in a 
manner that would render the issuance and sale of the Class A Note pursuant 
to this Agreement a violation of Section 5 of the Securities Act.

     SECTION 4.2    REPRESENTATIONS AND WARRANTIES AND AGREEMENTS OF WLFC.

     WLFC hereby represents (as of the Effective Date and as of each date on 
which a Loan is made by a Class A Noteholder pursuant to the Supplement, 
unless otherwise indicated) and warrants to, and agrees with, the Purchaser 
that:

           (i)      The representations and warranties made by WLFC in this 
Note Purchase Agreement, the Guaranty, the Contribution and Sale Agreement, 
the Servicing Agreement and any other Related Document to which it is a party 
(collectively, the "WLFC Documents") are true and correct in all material 
respects and the Purchaser shall be entitled to rely on such representations 
and warranties;

           (ii)     No written materials delivered to the Purchaser by or on 
behalf of WLFC in connection with the sale of the Class A Note contain any 
untrue statement of a material fact or omit a material fact necessary to make 
the statements contained therein or herein not misleading.  There is no fact 
peculiar to WLFC or any Affiliate of WLFC or, to the knowledge of WLFC, any 
Lease Agreement, Lessee or Engine which WLFC had not disclosed to the Deal 
Agent in writing which materially affects adversely or, so far as WLFC can 
now reasonably foresee, will materially affect adversely the ability of WLFC 
to perform the transactions contemplated hereby and by the Indenture, the 
Supplement, the Servicing Agreement and the Class A Note;

           (iii)    Any taxes, fees and other governmental charges payable by 
WLFC on or prior to the Effective Date in connection with the execution and 
delivery of the WLFC Documents, have been, or will be, paid on or prior to 
the Effective Date;

           (iv)     To the extent that the Exchange Act may be deemed to 
apply to the Class A Note and the Loans, none of the transactions 
contemplated herein (including, without limitation thereof, the use of the 
proceeds from the sale of the Class A Note) will violate or result in a 
violation of Section 7 of the Exchange Act or any regulations issued pursuant 
thereto including, without limitation, Regulations T, U and X of the Federal 
Reserve Board, 12 C.F.R., Chapter II.  WLFC will not use any distribution 
from the Issuer of proceeds received by the Issuer from the sale of the Class 
A Note to purchase or carry, directly or indirectly, margin stock;

           (v)      No event has occurred and is continuing that constitutes, 
or with the passage of time or the giving of notice or both would constitute 
an Early Amortization Event 

                                      15
<PAGE>

under, and as defined in, the Servicing Agreement or the Indenture and the 
Supplement, respectively.  WLFC is not in violation in any material respect 
of any term of any agreement, charter instrument, by-law or other instrument 
to which it is a party or by which it is or may be bound;

           (vi)     The aggregate amount of Scheduled Payments payable by the 
Lessees under the Lease Agreements during each Collection Period is 
sufficient to cover the monthly Servicing Fee, and pay the principal and 
interest on the Class A Note, as such payments become due and payable, in 
accordance with the Indenture and the Supplement; and

           (vii)    To the extent that the Securities Act may be deemed to 
apply to the Class A Note and the Loans, neither WLFC nor any affiliate (as 
defined in Rule 501(b) of Regulation D) of WLFC has directly, or through any 
agent, including, without limitation, First Union, (i) sold, offered for 
sale, solicited offers to buy or otherwise negotiated in respect of, any 
security (as defined in the Securities Act) which is or will be integrated 
with the sale of the Class A Note in a manner that would render the issuance 
and sale of the Class A Note a violation of the Securities Act or require the 
registration of the Class A Note under the Securities Act or (ii) engaged in 
any form of general solicitation or general advertising (within the meaning 
of Regulation D) in connection with the offering of the Class A Note.  It is 
not necessary in connection with the offer, sale and delivery of the Class A 
Note to register the Class A Note under the Securities Act.

                                   INDEMNIFICATION

     SECTION 6.1    INDEMNITIES BY THE ISSUER.

     Without limiting any other rights which the Deal Agent, the Purchasers 
or any of their respective Affiliates may have hereunder or under applicable 
law, the Issuer hereby agrees to indemnify each of the Deal Agent, the 
Purchasers and each of their respective Affiliates, together with their 
respective successors and permitted assigns (each of the foregoing Persons 
being individually called an "Indemnified Party") from and against any and 
all damages, losses, claims, liabilities and related costs and expenses, 
including reasonable attorneys' fees and disbursements (all of the foregoing 
being collectively referred to as "Indemnified Amounts") awarded against or 
incurred by any of them arising out of, or resulting from the breach by the 
Issuer or the Servicer of any representation, warranty, covenant or 
obligation of the Issuer or the Servicer of, this Agreement, any Deal 
Document or the  Class A Note, excluding, however, Indemnified Amounts to the 
extent resulting from gross negligence or willful misconduct on the part of 
such Indemnified Party.

     Any amounts subject to the indemnification provisions of this Section 
6.1 shall be paid by the Issuer to the Deal Agent within ten (10) Business 
Days following the Deal Agent's demand therefor.  Notwithstanding anything to 
the contrary, the Issuer's obligations to make payments under this Section 
6.1 shall be limited solely to funds available from time to time for such 
purpose pursuant to Section 3.2 of the Supplement and to the extent they are 
not so paid, such obligations shall not constitute a claim against the Issuer 
or the Collateral.

                                     ARTICLE VII

                                    THE DEAL AGENT

     SECTION 7.1    AUTHORIZATION AND ACTION OF THE DEAL AGENT.

     Each Purchaser hereby designates and appoints FCM as Deal Agent 
hereunder, and authorizes the Deal Agent to take such actions as agent on its 
behalf and to exercise such powers as are delegated to the Deal Agent by the 
terms of this Agreement together with such powers as are reasonably 
incidental thereto.  The Deal Agent shall not have any duties or 
responsibilities, except those expressly set forth herein, or any fiduciary 
relationship with any Purchaser, and no 

                                      17
<PAGE>

implied covenants, functions, responsibilities, duties, obligations or 
liabilities on the part of the Deal Agent shall be read into this Agreement 
or otherwise exist for the Deal Agent.  In performing its functions and 
duties hereunder, the Deal Agent shall act solely as agent for the Purchasers 
and does not assume nor shall be deemed to have assumed any obligation or 
relationship of trust or agency with or for the Issuer or any of its 
successors or assigns.  The Deal Agent shall not be required to take any 
action which exposes the Deal Agent to personal liability or which is 
contrary to this Agreement, any other agreement by which the Deal Agent is 
bound or applicable law.  The appointment and authority of the Deal Agent 
hereunder shall terminate on the Collection Date.

     SECTION 7.2    DELEGATION OF DUTIES.

     The Deal Agent may execute any of its duties under this Agreement by or 
through agents or attorneys-in-fact and shall be entitled to advice of 
counsel concerning all matters pertaining to such duties.  The Deal Agent 
shall not be responsible for the negligence or misconduct of any agents or 
attorneys-in-fact selected by it with reasonable care.

     SECTION 7.3    EXCULPATORY PROVISIONS.

     Neither the Deal Agent nor any of its directors, officers, agents or 
employees shall be (i) liable for any action lawfully taken or omitted to be 
taken by it or them under or in connection with this Agreement (except for 
its, their or such Person's own gross negligence or willful misconduct) or 
(ii) responsible in any manner to any of the Purchasers for any recitals, 
statements, representations or warranties made by the Issuer contained in 
this Agreement or in any certificate, report, statement or other document 
referred to or provided for in, or received under or in connection with, this 
Agreement or for the value, validity, effectiveness, genuineness, 
enforceability or sufficiency of this Agreement or any other document 
furnished in connection herewith, or for any failure of the Issuer to perform 
its obligations hereunder, or for the satisfaction of any condition specified 
in Article III.  The Deal Agent shall not be under any obligation to any 
Purchaser to ascertain or to inquire as to the observance or performance of 
any of the agreements or covenants contained in, or conditions of, this 
Agreement, or to inspect the properties, books or records of the Issuer.  The 
Deal Agent shall not be deemed to have knowledge of any Event of Default or 
Early Amortization Event unless the Deal Agent has received written notice 
from the Issuer, the Indenture Trustee or a Purchaser.

     SECTION 7.4    RELIANCE.

     The Deal Agent shall in all cases be entitled to rely, and shall be 
fully protected in relying, upon any document or conversation believed by it 
to be genuine and correct and to have been signed, sent or made by the proper 
Person or Persons and upon advice and statements of legal counsel (including, 
without limitation, counsel to the Issuer), independent accountants and other 
experts selected by the Deal Agent.  The Deal Agent shall in all cases be 
fully justified in failing or refusing to take any action under this 
Agreement or any other document furnished in connection herewith unless it 
shall first receive such advice or concurrence of VFCC or all of the 
Purchasers, as applicable, as it deems appropriate or it shall first be 
indemnified to its satisfaction 

                                      18
<PAGE>

by the Purchasers, PROVIDED that unless and until the Deal Agent shall have 
received such advice, the Deal Agent may take or refrain from taking any 
action, as the Deal Agent shall deem advisable and in the best interests of 
the Purchasers. The Deal Agent shall in all cases be fully protected in 
acting, or in refraining from acting, in accordance with a request of VFCC or 
all of the Purchasers, as applicable, and such request and any action taken 
or failure to act pursuant thereto shall be binding upon all the Purchasers.

     SECTION 7.5    NON-RELIANCE ON DEAL AGENT AND OTHER PURCHASERS.

     Each Purchaser expressly acknowledges that none of the Deal Agent or any 
of their respective officers, directors, employees, agents, attorneys-in-fact 
or affiliates has made any representations or warranties to it and that no 
act by the Deal Agent hereafter taken, including, without limitation, any 
review of the affairs of the Issuer, shall be deemed to constitute any 
representation or warranty by the Deal Agent.  Each Purchaser represents and 
warrants to the Deal Agent that it has made and will make, independently and 
without reliance upon the Deal Agent or any other Purchaser and based on such 
documents and information as it has deemed appropriate, its own appraisal of 
and investigation into the business, operations, property, prospects, 
financial and other conditions and creditworthiness of the Issuer and made 
its own decision to enter into this Agreement.

     SECTION 7.6    DEAL AGENT IN ITS INDIVIDUAL CAPACITY.

     Any of the Deal Agent and its Affiliates may make loans to, accept 
deposits from and generally engage in any kind of business with the Issuer or 
any Affiliate of the Issuer as though the Deal Agent were not the Deal Agent 
hereunder.  With respect to the acquisition of the Class A Note pursuant to 
this Agreement, each of the Deal Agent and its Affiliates shall have the same 
rights and powers under this Agreement as any Purchaser and may exercise the 
same as though it were not the Deal Agent and the terms "Purchaser" and 
"Purchasers" shall include the Deal Agent in its individual capacity, if the 
Deal Agent shall become a Purchaser hereunder.

     SECTION 7.7    SUCCESSOR DEAL AGENT.

     The Deal Agent may, upon 5 days' notice to the Issuer and the 
Purchasers, and the Deal Agent will, upon the direction of all of the 
Purchasers (other than the Deal Agent, in its individual capacity), resign as 
Deal Agent.  If the Deal Agent shall resign, then VFCC during such 5-day 
period shall appoint from among the Purchasers a successor agent.  If for any 
reason no successor Deal Agent is appointed by VFCC during such 5-day period, 
then effective upon the termination of such 5-day period, the Purchasers 
shall perform all of the duties of the Deal Agent hereunder and the Issuer 
shall for all purposes deal directly with the Purchasers.  After any retiring 
Deal Agent's resignation hereunder as Deal Agent, the provisions of this 
Article VII and Article VI shall inure to its benefit as to any actions taken 
or omitted to be taken by it while it was Deal Agent under this Agreement.  
The retiring Deal Agent shall provide prompt written notice of its 
resignation hereunder to each Rating Agency.

hereto and, to the extent that rights and obligations hereunder have been 
assigned to it pursuant to such Assignment and Acceptance, have the rights 
and obligations of an Investor hereunder and (ii) the Investor assignor 
thereunder shall, to the extent that rights and obligations hereunder have 
been assigned by it pursuant to such Assignment and Acceptance, relinquish 
its rights and be released from its obligations under this Agreement (and, in 
the case of an Assignment and Acceptance covering all or the remaining 
portion of an assigning Investor's rights and obligations under this 
Agreement, such Investor shall cease to be a party hereto).

     (b)   By executing and delivering an Assignment and Acceptance, the

together with such powers as are reasonably incidental thereto; and (vii) 
such assignee agrees that it will perform in accordance with their terms all 
of the obligations which by the terms of this Agreement are required to be 
performed by it as an Investor.

     (c)   The Deal Agent shall maintain at its address referred to herein a 
copy of each Assignment and Acceptance delivered to and accepted by it and a 
register for the recordation of the names and addresses of the Investors and 
the Commitment of, and the Capital of, each Asset interest owned by each 
investor from time to time (the "REGISTER").  The entries in the Register 
shall be conclusive and binding for all purposes, absent manifest error, and 
VFCC, the Seller and the Investors may treat each Person whose name is 
recorded in the Register as an Investor hereunder for all purposes of this 
Agreement.  The Register shall be available for inspection by VFCC, the 
Liquidity Agent or any Investor at any reasonable time and from time to time 
upon reasonable prior notice.

     (d)   Subject to the provisions of Section 8.1(a), upon its receipt of 
an Assignment and Acceptance executed by an assigning Investor and an 
assignee, the Deal Agent and the Liquidity Agent shall each, if such 
Assignment and Acceptance has been completed and is in substantially the form

Agent shall then (i) record the information contained therein in the Register 
and (ii) give prompt notice thereof to VFCC.

     (e)   Each Investor may sell participations to one or more banks or 
other entities in or to all or a portion of its rights and obligations under

Commitment and each Asset Interest owned by it); PROVIDED, HOWEVER, that (i) 
such Investor's obligations under this Agreement (including, without 
limitation, its Commitment hereunder) shall remain unchanged, (ii) such 
Investor shall remain solely responsible to the other parties hereto for the 
performance of such obligations and (iii) the Deal Agent and the other 
Investors shall continue to deal solely and directly with such Investor in 
connection with such Investor's rights and obligations under this Agreement, 
and PROVIDED 

                                      21
<PAGE>

FURTHER that the Deal Agent shall have confirmed that upon the effective date 
of such participation the provisions of Section 3.03(f) of the VFCC 
Administration Agreement shall be satisfied. Notwithstanding anything herein 
to the contrary, each participant shall have the rights of an Investor 
(including any right to receive payment) under Sections 2.8 and 2.9; 
PROVIDED, HOWEVER, that no participant shall be entitled to receive payment 
under either such Section in excess of the amount that would have been 
payable under such Section by the Seller to the Investor granting its 
participation had such participation not been granted, and no Investor 
granting a participation shall be entitled to receive payment under either 
such Section in an amount which exceeds the sum of (i) the amount to which 
such Investor is entitled under such Section with respect to any portion of 
any Asset Interest owned by such Investor which is not subject to any 
participation PLUS (ii) the aggregate amount to which its participants are 
entitled under such Sections with respect to the amounts of their respective 
participations.  With respect to any participation described in this Section 
8.1, the participant's rights as set forth in the agreement between such 
participant and the applicable Investor to agree to or to restrict such 
Investor's ability to agree to any modification, waiver or release of any of 
the terms of this Agreement or to exercise or refrain from exercising any 
powers or rights which such Investor may have under or in respect of this 
Agreement shall be limited to the right to consent to any of the matters set 
forth in Section 9.1 of this Agreement.

     (f)   Each Investor may, in connection with any assignment or 
participation or proposed assignment or participation pursuant to this 
Section 8.1, disclose to the assignee or participant or proposed assignee or 
participant any information relating to the Seller or VFCC furnished to such 
Investor by or on behalf of the Seller or VFCC.

     (g)   In the event (i) an Investor ceases to qualify as an Eligible 
Assignee, or (ii) an Investor makes demand for compensation pursuant to 
Section 2.8 or Section 2.9, VFCC may, and, upon the direction of the Seller 
and prior to the occurrence of an Early Amortization Event, shall, in any 
such case, notwithstanding any provision to the contrary herein, replace such 
Investor with an Eligible Assignee by giving three Business Days' prior 
written notice to such Investor.  In the event of the replacement of an 
Investor, such Investor agrees (i) to assign all of its rights and 
obligations hereunder to an Eligible Assignee selected by VFCC upon payment 
to such Investor of the amount of such Investor's Asset Interests together 
with any accrued and unpaid Yield thereon, all accrued and unpaid commitment 
fees owing to such Investor and all other amounts owing to such Investor 
hereunder and (ii) to execute and deliver an Assignment and Acceptance and 
such other documents evidencing such assignment as shall be necessary or 
reasonably requested by VFCC or the Deal Agent.  In the event that any 
Investor ceases to qualify as an Eligible Assignee, such affected Investor 
agrees (1) to give the Deal Agent, the Seller and VFCC prompt written notice 
thereof and (2) subject to the following proviso, to reimburse the Deal 
Agent, the Liquidity Agent, the Seller, VFCC and the relevant assignee for 
all fees, costs and expenses (including, without limitation, the reasonable 
fees and out-of-pocket expenses of counsel for each of the Deal Agent, the 
Liquidity Agent, the Seller and VFCC and such assignee) incurred by the Deal 
Agent, the Liquidity Agent, the Seller, VFCC and such assignee, respectively, 
in connection with any assignment made pursuant to this Section 8.1(g) by 
such affected Investor; PROVIDED, HOWEVER, that such affected Investor's 
liability for such 

                                      22
<PAGE>

costs, fees and expenses shall be limited to the amount of any up-front fees 
paid to such affected Investor at the time that it became a party to this 
Agreement.

     (h)   Nothing herein shall prohibit any Investor from pledging or 
assigning as collateral any of its rights under this Agreement to any Federal 
Reserve Bank in accordance with applicable law and any such pledge or 
collateral assignment may be made without compliance with Section 8.1(a) or 
Section 8.1(b).

     (i)   In the event any Investor causes Increased Costs, expenses or 
Taxes to be incurred by the Deal Agent, Liquidity Agent or VFCC in connection 
with the assignment or participation of such Investor's rights and 
obligations under this Agreement to an Eligible Assignee then such Investor 
agrees that it will make reasonable efforts to assign such Increased Costs, 
expenses or Taxes to such Eligible Assignee in accordance with the provisions 
of this Agreement.

     (j)   VFCC may at any time assign, or a security interest in or sell a 
participation interest in, any Asset Interest (or portion thereof) to any 
Person.  The parties to any such assignment, or sale of participation 
interest, shall execute and deliver to the Deal Agent, for its acceptance and 
recording in its books and records, such agreement or document as may be 
satisfactory to such parties and the Deal Agent.

     the Class A Note or (D) amend or modify any defined term (or any defined
     term used directly or indirectly in such defined term) used in clauses (A)
     through (C) above in a manner which would circumvent the intention of the
     restrictions set forth in such clauses; or

<PAGE>

           (ii)     without the written consent of the then Deal Agent, amend,

     SECTION 9.3    NO WAIVER; REMEDIES.

     No failure on the part of the Deal Agent or a Purchaser to exercise, and 
no delay in exercising, any right hereunder shall operate as a waiver

     SECTION 9.5    RECOURSE AGAINST CERTAIN PARTIES.

     (a)   No recourse under or with respect to any obligation, covenant or 
agreement (including, without limitation, the payment of any fees or any

the Deal Agent as contained in the Deal Documents or any other agreement, 
instrument or document entered into by it pursuant hereto or in connection 
herewith shall be had against any administrator of such party or any 
incorporator, affiliate, stockholder, officer, employee or director of such 
party or of any such administrator, as such, by the enforcement of any 
assessment or by any legal or equitable proceeding, by virtue of any statute 
or otherwise; IT BEING EXPRESSLY AGREED AND UNDERSTOOD that the agreements of 
such party contained in the Deal Documents and all of the other agreements, 
instruments and documents entered into by it pursuant hereto or in connection 
herewith are, in each case, solely the corporate obligations of such party, 
PROVIDED THAT, in the case of VFCC, such liabilities shall be paid only after 
the repayment in full of all Commercial Paper and all other liabilities 
contemplated in the program documents with respect to VFCC, and that no 
personal liability whatsoever shall attach to or be incurred by any 
administrator of such party or any incorporator, stockholder, affiliate, 
officer, employee or director of such party or of any such administrator, as 
such, or any of them, under or by reason of any of the obligations, covenants 
or agreements of such Purchaser contained in the Deal Documents or in any 
other such instrument, document or agreement, or which are implied therefrom, 
and that any and all personal liability of every such administrator of such 
party and each incorporator, stockholder, affiliate, officer, employee or 
director of such party or of any such administrator, or any of them, for 
breaches by such party of any such obligations, covenants or agreements, 
which liability may arise either at common law or in equity, by statute or

amount required to be paid by it hereunder or in excess of any amount 
available to VFCC after paying or making provision for the payment of its 
Commercial Paper.  All payment obligations of VFCC hereunder thereunder are 
contingent upon the availability of funds in excess of the amounts necessary

Liquidity Agent, the Servicer and each Investor agrees that they shall not 
have a claim under Section 101(5) of the United States Bankruptcy Code if and 
to the extent that any such payment obligation exceeds the amount available

of this Agreement.

with respect to enforcing their respective rights and remedies as against the 
Issuer under this Agreement, the Indenture, any Class A Note, any other Deal 
Document and the other documents to be delivered hereunder or in connection 
herewith; PROVIDED, however, that none of the Deal Agent, any Purchaser or 
any affiliate thereof shall be entitled to any such payment (and shall 
reimburse the Issuer for any such payments previously received) if such 
person has been determined by a court of competent jurisdiction to not be 
entitled to receive indemnification pursuant to Article VI hereof in 
connection with such enforcement.  The Issuer also agrees to pay on demand 
all costs and expenses of the Purchasers and the Deal Agent, and their 
respective Affiliates, successors or assigns, if any (including reasonable 
counsel fees and expenses), incurred in connection with the negotiation, 
execution, and delivery of this Agreement and the transactions contemplated 
hereby and/or the enforcement, administration (including periodic auditing), 
amendment or modification of, or any waiver or consent issued in connection

hereunder, including, without limitation, the reasonable fees and 
out-of-pocket expenses of counsel for Purchaser and the Deal Agent with 
respect thereto and with respect to advising the Purchaser and the Deal Agent 
as to their rights and remedies under this Agreement, the Deal Documents and 
the other agreements executed pursuant hereto. Any amounts subject to the 
provisions of this Section 9.10 shall be paid by the Issuer to the Deal Agent 
within ten (10) Business Days following the Deal Agent's written demand 
therefor.  Notwithstanding anything to the contrary, the Issuer's obligations 
to make payments under this Section 9.10 shall be limited solely to funds 
available from time to time for such purpose pursuant to Section 3.2 of the 
Supplement and to the extent they are not so paid, such obligations shall not 
constitute a claim against the Issuer or the Collateral.

     SECTION 9.11   RATABLE PAYMENTS.

     If any Purchaser, whether by setoff or otherwise, has payment made to it 
with respect to any portion of any amount of the principal amount of the 
Class A Note or other amount owing to such Purchaser (other than payments 
received pursuant to Article VI) in a greater proportion than that received 
by any other Purchaser, such Purchaser agrees, promptly upon demand, to pay 
to the Deal Agent, for distribution ratably to all other Purchasers, the 
amount of such excess such that all Purchasers shall receive their ratable 
portion of such payment. 

     SECTION 9.12   CONFIDENTIALITY.

     (a)   Each of the Deal Agent, the Purchasers and the Issuer shall 
maintain and shall cause each of its employees and officers to maintain the 
confidentiality of this Agreement and the other confidential proprietary 
information with respect to the other parties hereto and their respective 
businesses obtained by it or them in connection with the structuring, 
negotiating and execution of the transactions contemplated herein, except 
that each such party and its officers and employees may (i) disclose such 
information to its external accountants and attorneys and as required by 
applicable law, applicable accounting requirements or order of any judicial 
or administrative proceeding and (ii) disclose the existence of this 
Agreement, but not the financial terms thereof.

     (b)   Anything herein to the contrary notwithstanding, the Issuer hereby 
consents to the disclosure of any nonpublic information with respect to it 
(i) to the Deal Agent, the Liquidity Agent, the Investors, prospective 
Investors or a Purchaser by each other, (ii) by the Deal Agent or the 
Purchasers to any prospective or actual assignee or participant of any of 
them or (iii) by the Deal Agent to any rating agency that provides a rating 
for the Commercial Paper, Commercial Paper dealer or placement agent or 
provider of a surety, guaranty or credit or liquidity enhancement to a 
Purchaser and to any officers, directors, employees, outside accountants and 
attorneys of any of the foregoing, provided each such Person is informed of 
the confidential nature of such information and agrees to keep such 
information confidential pursuant to the terms of this Section 8.10.  In 
addition, the Purchasers, the Liquidity Agent, the Investors and the Deal 
Agent may disclose any such nonpublic information pursuant to any law, rule, 
regulation, direction, request or order of any judicial, administrative or 
regulatory authority or proceedings (whether or not having the force or 
effect of law).  As used herein, the terms "Investors" and the "Liquidity 
Agent" shall have their respective meanings as set forth in the Liquidity 
Purchase Agreement.

     SECTION 9.13   EXECUTION IN COUNTERPARTS; SEVERABILITY; INTEGRATION.

     This Agreement may be executed in any number of counterparts and by 
different parties hereto in separate counterparts, each of which when so 
executed shall be deemed to be an original and all of which when taken 
together shall constitute one and the same agreement.  In case any provision 
in or obligation under this Agreement shall be invalid, illegal or 
unenforceable in any jurisdiction, the validity, legality and enforceability 
of the remaining 

                                      28

provisions or obligations, or of such provision or obligation in any other 
jurisdiction, shall not in any way be affected or impaired thereby.  This 
Agreement contains the final and complete integration of all prior 
expressions by the parties hereto with respect to the subject matter hereof 
and shall constitute the entire agreement among the parties hereto with 
respect to the subject matter hereof, superseding all prior oral or written 
understandings.

make such withdrawal except upon presentation of supporting documentation 
reasonably determined by the Deal Agent to comply with the terms of the 
applicable Lease Agreement (which shall evidence its determination by written

contributions to fund benefits) with respect to any Plan of Issuer, or Plan 
subject to Title IV of ERISA of any ERISA Affiliate, has been, or is expected 
to be, incurred by Issuer or an ERISA Affiliate, either directly or 
indirectly.  All Plans of Issuer are in material compliance with ERISA and 
the Code.  No lien under Section 412 of the Code or 302(f) of ERISA or 
requirement to provide security under the Code or ERISA has been or is 
reasonably expected by Issuer to be imposed on its assets.  The Issuer does 
not have any obligation under any collective bargaining agreement. As of the

security interest created thereby to vest in the Indenture Trustee in order 
to insure the first priority perfected security interest of the Indenture 
Trustee (for the benefit of the Series 1997-1 Noteholders) in the Collateral. 
 Each Lease Agreement is "chattel paper" (under the UCC, if the UCC is in 
effect in the jurisdiction whose law governs the Lease Agreement).  All 
executed counterparts of each Lease Agreement (other than the one held by the 
related Lessee or filed with any relevant Governmental Authority) that 
constitutes "chattel paper" are in the possession of the Indenture Trustee.

     SECTION 6.24.     ELIGIBLE LEASE AGREEMENTS; ELIGIBLE ENGINES.
