                        WILLIS LEASE FINANCE CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of presentation

Consolidated Financial Statements

The accompanying  unaudited  consolidated  financial  statements of Willis Lease
Finance Corporation (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  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 Stockholders
incorporated  by reference in the Company's  Annual Report on Form 10-KA for the
fiscal year ended December 31, 1996.

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

2. Management Estimates

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

3. Employee Stock Purchase Plan

The Company's  Employee Stock Purchase Plan (the "Purchase Plan") was adopted by
the Board of  Directors  on June 21,  1996 and  filed  with the  Securities  and
Exchange  Commission on November 1, 1996. The Purchase Plan is designed to allow
eligible  employees of the Company and  participating  subsidiaries  to purchase
shares of Common Stock, at semi-annual intervals, through their periodic payroll
deduction  under the Purchase  Plan.  The purchase price is the lesser of 85% of
the market price of the Common Stock at the beginning of each purchase  interval
or 85% of the  market  price of the  Common  Stock  at the end of each  purchase
interval.  A reserve of 75,000 shares of common stock has been  established  for
this  purpose.  During the six month  period  ended June 30,  1997,  the Company
issued  4,068  shares of Common  Stock as a result of employee  stock  purchases
under the plan.

4. Financing

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

5. Subsequent event

In July 1997, the Company increased its $15 million revolving credit facility to
$30 million.

6. Pro Forma Net Income Per Share

Net income per share has been  computed by dividing  net income by the number of
shares of Willis Lease Finance  Corporation  common stock issued to the original
shareholder  (3,110,657 shares), plus common stock issued in connection with the
Initial  Public  Offering  (2,316,136  shares),  warrants  and options  (400,000
shares) and shares issued in the six months ended June 30, 1997 (11,568  shares)
diluted on a weighted average basis for the period.  This calculation results in
a weighted  average number of shares  outstanding of 5,553,920 and 3,110,657 for
the six months ended June 30, 1997 and June 30, 1996, respectively.

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


Overview

The Company's primary  businesses are the leasing of spare replacement  aircraft
engines,  spare  parts  packages  and the  strategic  acquisition  and resale of
aircraft engines and parts to the worldwide commercial airline aftermarket.  The
Company commenced leasing operations in 1988 and established Willis Aeronautical
Services,  Inc., ("WASI") to conduct its spare parts resale operation in October
1994.  Revenue  consists  primarily of operating lease revenue,  income from the
sale of leased engines, sales of spare parts and components and equipment sales.

Summary of Financial Results for the Quarter Ended June 30, 1997. Total revenues
for the  quarter  ending  June 30,  1997 were $15.9  million,  compared  to $9.2
million  in the  corresponding  quarter of 1996.  This  increase  resulted  from
increased  revenue due to a higher  asset base,  higher spare parts sales and an
increase in sale of equipment  acquired  for resale.  Net income for the quarter
ending  June 30,  1997,  was  $1.3  million,  compared  to $0.7  million  in the
corresponding quarter of 1996.

Lease Portfolio.  During the quarter ended June 30, 1997, six engines were added
to the Company's  operating and direct finance lease  portfolios at a total cost
of  $18.7  million.  One  engine  with a net  book  value  of $3.2  million  was
transferred  from the lease  portfolio  into the  equipment  acquired for resale
portfolio and subsequently sold for $3.6 million.

Operating  Leases.  Operating  lease revenue for the three months ended June 30,
1997 increased 31% to $4.4 million from $3.4 million from the comparable  period
in 1996. This increase reflects lease revenues from additional engines and spare
parts packages acquired after June 30, 1996 ($1.3 million), one engine off-lease
during the  quarter  ended June 30, 1996 but on lease  during the quarter  ended
June 30, 1997 ($0.1  million) and net increases in effective  lease rates on the
existing  portfolio  ($0.2  million).  Offsetting this increase is a decrease of
lease  revenue of $0.6 million  from  engines on lease during the quarter  ended
June 30, 1996 and sold or otherwise disposed of prior to April 1, 1997.

Net income is not materially  affected in the short term by lease volume. In the
early  years of a lease,  much of the lease  revenue  is  offset  by the  higher
interest  expense.  Accordingly,  the timing of new lease volume does not have a
material effect on the near-term quarterly net income.

Expenses  directly  related to operating  lease  activity  increased 45% to $2.7
million for the three months ended June 30, 1997 from the  comparable  period in
1996.  Interest expense increased 50% to $1.6 million for the three months ended
June 30, 1997 from the comparable  period in 1996, due primarily to an increased
loan base and the replacement of the existing facility with a new loan agreement
bearing a higher  interest rate in the first quarter of 1997.  Residual  sharing
expenses  increased  19% to $181,000 from the  comparable  period in 1996 due to
changes  in the  Company's  portfolio  of engines  subject  to such  agreements.
Depreciation  expense  increased 43% to $930,000 for the three months ended June
30,  1997 from the  comparable  period in 1996,  due to the larger  asset  base,
offset by  accelerated  depreciation  on one engine in 1996;  this engine is not
depreciated on an accelerated basis in 1997.

Spare  Parts  Sales.  Revenues  from spare parts  sales  increased  218% to $3.7
million and the gross  margin  increased  to 34% for the three months ended June
30, 1997 from 25% in the  corresponding  period in 1996, due to higher volume of
spare parts sales.

Equipment Sales. During the three months ended June 30, 1997, the Company sold 4
engines for $7.6 million which  resulted in a gain of $1.2 million,  compared to
the three months  ended June 30,  1996,  during which the Company sold 2 engines
for $4.6 million resulting in a gain of $0.7 million.

Interest and Other Income.  Interest and other income for the three months ended
June 30, 1997 increased to $201,000 from $46,000 for the three months ended June
30, 1996.  This is a result of interest  earned on deposits held,  primarily the
proceeds from the Company's initial public offering.

General  and  Administrative  Expenses.   General  and  administrative  expenses
increased  81% to $2.2 million for the three months ended June 30, 1997 from the
comparable  period in 1996. This increase reflects  additional  compensation and
related benefits,  telephone and travel costs due to staff additions,  increased
rent due to the expansion of the WASI  facility and an increase in  professional
fees incurred by the Company and public  company costs  incurred in 1997. In the
past  twelve  months,  the  Company  has  increased  its  staff to 32  full-time
employees  and 2  part-time  employees,  up from 24  full-time  employees  and 1
part-time  employee a year ago as a result of its growth in assets and  increase
in transactions under consideration.

Results of Operations

Six months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996

Revenue is summarized as follows:
                                              Six Months Ended June 30,

                                            1997              1996

                                        =======================================
                                                             
                                                             
Lease  Portfolio.  During the first six months of 1997,  eight engines and three
spare parts  packages  (primarily  avionics)  were added to the Company's  lease
portfolio at a total cost of $25.8 million.  One engine with a net book value of
$603,000  was sold  from the  portfolio,  resulting  in a gain of  $397,000.  In
addition,  one engine with a net book value of $3.2 million was transferred from
the lease  portfolio  into the  equipment  acquired  for  resale  portfolio  and
subsequently sold for $3.6 million.

Operating Leases. Operating lease revenue for the six months ended June 30, 1997
increased  25% to $8.5 million from $6.8 million from the  comparable  period in
1996. This increase  reflects lease revenues from  additional  engines and spare
parts packages acquired after June 30, 1996 ($2.2 million), one engine off-lease
during the six months  ended  June 30,  1996 but on lease  during the six months
ended June 30,  1997  ($0.3  million)  and an  increase  of one engine  that was
partially  on lease  during the six months  ended June 30, 1996 but was on lease
for the entire six months ended June 30, 1997 ($0.2  million).  Offsetting  this
increase is a decrease in lease  revenue of $0.5  million  from engines on lease
during the six months  ended June 30,  1996 and sold or  otherwise  disposed  of
prior to January 1, 1997. In addition,  there was a decrease in lease revenue of
$0.5 million on three  engines due to lower lease rates in 1997,  when  compared
with the six months ended June 30, 1996.

Net income is not materially  affected in the short term by lease volume. In the
early  years of a lease,  much of the lease  revenue  is  offset  by the  higher
interest  expense.  Accordingly,  the timing of new lease volume does not have a
material effect on the near-term quarterly net income.

Expenses  directly  related to operating  lease  activity  increased 21% to $5.2
million  for the six months  ended June 30, 1997 from the  comparable  period in
1996.  Interest  expense  increased 39% to $3.1 million for the six months ended
June 30, 1997 from the comparable  period in 1996, due primarily to an increased
loan base and the replacement of the existing facility with a new loan agreement
bearing a higher  interest rate in 1997.  Depreciation  expense  increased 2% to
$1.8  million for the six months ended June 30, 1997 from  comparable  period in
1996, due to the larger asset base,  offset by accelerated  depreciation  on one
engine in 1996, no longer applicable in 1997.

Spare Parts Sales. Revenues from spare parts sales increased 41% to $5.9 million
and the gross  margin  decreased  to 37% in 1997  from 43% in the  corresponding
period in 1996, due to changes in the inventory mix of parts sold.

Equipment  Sales.  During the six months ended June 30, 1997, the Company sold 5
engines for $10.1 million which resulted in a gain of $1.5 million,  compared to
the six months ended June 30, 1996,  during which the Company sold 3 engines for
$6.8 million resulting in a gain of $1.3 million.

Interest  and Other  Income.  Interest and other income for the six months ended
June 30, 1997  increased to $453,000  from $47,000 for the six months ended June
30, 1996.  This is a result of interest  earned on deposits held,  primarily the
proceeds from the Company's initial public offering.

General  and  Administrative  Expenses.   General  and  administrative  expenses
increased  88% to $3.9  million for the six months  ended June 30, 1997 from the
comparable  period in 1996. This increase reflects  additional  compensation and
related benefits,  telephone and travel costs due to staff additions,  increased
rent  due to the  expansion  of the WASI  facility,  as well as an  increase  in
professional  fees,  insurance  expense and public company costs incurred by the
Company in 1997.

Liquidity and Capital Resources


In June 1997, the Company  obtained a $15 million  revolving  credit facility to
finance the acquisition of engines and high-value spare parts for sale or lease.
This facility,  which expires on February 28, 1998, bears interest at prime plus
75 basis points and may be renewed annually. In July 1997, the Company increased
its $15 million revolving credit facility to $30 million.

At June 30, 1997,  $56 million of the  Company's  borrowings  were on a variable
rate basis,  substantially  all of which bears  interest at LIBOR plus 2.5%. The
Company's  engine  leases are  generally  structured  at fixed  rental rates for
specific  terms.  To date,  this variable  rate  borrowing has resulted in lower
interest  expense for the Company.  In September 1996, the Company  purchased an
interest rate cap from an investment grade financial institution for $460,000 to
limit its exposure to  increases in interest  rates on a portion of its variable
rate  borrowings.  The cap has a notional  principal amount of $39.0 million and
caps the  Company's  exposure to interest  rate  increases  for a period of four
years to a maximum fixed  interest  rate of 8.66%.  The cost of the cap is being
amortized  over four years.  The  Company  will be exposed to credit risk in the
event of non-performance by the counterparty to the cap.

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 the
future, the Company does not expect to enter into any variable rate loans except
in those instances where it obtains a variable rate lease from its customers and
anticipates  reducing its  remaining  variable rate  borrowings  during the next
three years,  after which the Company will  re-evaluate its exposure to interest
rate variations.

As of June 30, 1997, the Company has four engines and three spare parts packages
which have not been financed. Until such permanent financing is in place, two of
the  engines  and the three  spare parts  packages  have  interest  rate risk if
interest  rates  increase,  since the  underlying  lease  revenue is fixed.  The
Company will seek permanent financing for the engines, although no assurance can
be given that permanent  financing will be available on favorable  terms,  if at
all.

The  Company  believes  that its  current  and  anticipated  credit  facilities,
internally  generated  funds and the net proceeds of the Initial Public Offering
("the  Offering"),  should  be  sufficient  to fund  the  Company's  anticipated
operations  until the first  quarter of 1998.  Thereafter,  the Company may seek
additional equity capital to fund projected  growth.  The Company has received a
letter of  commitment  from a  financial  institution  to provide an $80 million
securitized  warehouse facility for the financing of jet aircraft engines.  This
transaction's  structure  is indented  to  facilitate  future  public or private
securitized note issuances.  The facility will become available immediately upon
completion of definitive agreements. The warehouse facility requires the Company
to  hedge  50%  of  the  floating  rate  facility.   The  Company's  ability  to
successfully  execute its business strategy,  and to sustain its operations,  is
dependent  in part on its  ability to obtain debt  capital  and to raise  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 were unable to obtain any portion of required financing on favorable
terms,  the Company's  ability to add new engines to its portfolio or to conduct
profitable  operations  with its existing  asset base would be  impaired,  which
would  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

Factors That May Affect Future Results

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

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

The  Company  also  engages in the  short-term  trading of  commercial  aircraft
engines in the aftermarket.  Although it is the Company's  general policy not to
purchase engines on speculation,  the Company has and, if it deems  appropriate,
may in the future purchase  engines without having a commitment for the engines'
resale.  If the  Company  were to  purchase  an  engine  without  having  a firm
commitment  for its resale or if a firm  commitment for resale were to exist but
not be consummated for whatever reason,  the Company would be subject to all the
risks of ownership of the engine as described above.

The Company also engages in the  purchase and resale of  aftermarket  airframes,
airframe rotable parts, engine parts,  engines and modules.  Before parts may be
installed  in an  aircraft,  they  must  meet  certain  standards  of  condition
established by the Federal Aviation Administration ("FAA") and/or the equivalent
regulatory agencies in other countries.  Parts must also be traceable to sources
deemed  acceptable  by such  agencies.  Parts  owned by the Company may not meet
applicable standards or standards may change, causing parts which are already in
the Company's  inventory to be scrapped or modified.  Engine  manufacturers  may
also  develop  new parts to be used in lieu of parts  already  contained  in the
Company's inventory. In all such cases, to the extent the Company has such parts
in its inventory, their value may be reduced.

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

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


                                       14
<PAGE>


In 1996,  approximately  61% of the  Company's  lease  revenue was  generated by
leases to foreign  customers.  Such  leases  may  present  greater  risks to the
Company because certain  foreign laws,  regulations and judicial  procedures may
not be as protective of lessor rights as those which apply in the United States.
In addition,  many foreign  countries have currency and exchange laws regulating
the international  transfer of currencies.  To date, the Company has experienced
some collection  problems under certain leases with foreign airlines,  and there
can be no  assurance  that the  Company  will  not  experience  such  collection
problems in the future.  The Company  may also  experience  collection  problems
related to the enforcement of its lease  agreements under foreign local laws and
the  attendant  remedies in such locales  Section 1110 does not apply to lessees
located outside of the United States and applicable foreign laws may not provide
comparable  protection.  Consequently,  the Company is subject to the timing and
access to courts  and the  remedies  local laws  impose in order to collect  its
lease payments and recover its assets.

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

The Company has recently experienced significant growth in revenues. Such growth
has placed,  and is expected to continue to place,  a significant  strain on its
managerial, operational and financial resources. Due to the Company's rapid pace
of growth over the past year,  the Company has recently  added to its management
team. On June 17, 1997, Rae A. Capps,  formerly Vice President,  General Counsel
and Corporate Secretary for Hawaiian Airlines, joined the Company as Senior Vice
President and General Counsel.  On July 30, 1997, Donald A. Nunemaker,  formerly
President  and  CEO  of  LeasePartners,   Inc.,  joined  the  Company  as  Chief
Administrative  Officer and Executive Vice President.  There can be no assurance
that  the  Company  will be able to  effectively  manage  the  expansion  of its
operations,  or that the  Company's  systems,  procedures  or  controls  will be
adequate to support the  Company's  operations.  Any  inability  to  effectively
manage growth could have a material  adverse  effect on the Company's  business,
financial condition and results of operations.

                                  2. The Credit

         2.1. The Loans.  Subject to the terms and  conditions  herein set forth
and in reliance upon the  representations,  warranties  and covenants  contained
herein, CoreStates Bank agrees to make revolving credit loans ("Revolving Credit
Loans") to Willis  upon  receipt of loan  requests  therefor  in amounts  not to
exceed at any time outstanding,  in the aggregate,  $15,000,000 (such amount, as
the same may be reduced pursuant to ss.2.7 hereof being  hereinafter  called the
"Revolving  Loan  Commitment").  For  purposes  of  determining  the  amount  of
Revolving  Credit  Loans  outstanding,  the  Standby  Letters  of Credit  issued
pursuant to ss.2.2  hereof shall be deemed  Revolving  Credit Loans and shall be
added to the  Revolving  Credit Loans  outstanding  to determine  the  aggregate
Revolving Credit Loans  outstanding.  As provided below,  Revolving Credit Loans
may be  requested  by Willis,  and made from time to time prior to the  Revolver
Termination  Date.  All Loans  shall be made to Willis at the main office of the
Bank, Broad and Chestnut Streets, Philadelphia, Pennsylvania 19101.

         Revolving  Credit Loans may be made from time to time during the period
beginning  on the date hereof and ending on June 12, 1998 or on the earlier date
of termination in full,  pursuant to ss.2.7 or ss.8.1 hereof, of the obligations
of the Bank under this ss.2.1 (June 12, 1998 or such earlier date of termination
being herein called the "Revolver Termination Date").  Revolving Credit Loans at
the occasion of each borrowing shall be in aggregate  principal amounts at least
equal to $150,000 or, if less, the remaining unused amount of the Revolving Loan
Commitment.  Willis shall not be entitled to any Revolving Credit Loan if, after
giving effect to such Loan, the unpaid amount of the then outstanding  Revolving
Credit Loans would exceed the then current Borrowing Base. Prior to the Revolver
Termination  Date and within the limits of the Revolving Loan Commitment and the
Borrowing Base, Willis may borrow,  prepay and reborrow  Revolving Credit Loans.
All  Revolving  Credit Loans shall mature and be due and payable as set forth in
the  next  paragraph  of this  ss.2.1  unless  the  maturity  of said  Loans  is
accelerated as provided in ss.2.7 or ss.8.1 hereof.

         At the end of each Agreement Year, Willis may request that the Revolver
Termination  Date be extended for one full year by notifying  CoreStates Bank in
writing  not more  than 90 days nor  less  than 60 days  prior to the end of the
existing Agreement Year that it desires an extension of the Revolver Termination
Date.  If  CoreStates  Bank in its sole  discretion  shall  elect to extend  the
Revolver  Termination  Date for one full year, it shall notify Willis in writing
prior to the end of the existing Agreement Year that it is willing to extend the
Revolver  Termination  Date on the terms and  conditions  set forth  herein.  If
CoreStates  Bank shall not issue such written notice,  the Revolver  Termination
Date shall not be deemed  extended.  In the Event that the Revolver  Termination
Date is not extended and provided that the maturity date of the Revolving Credit
Loans has not been  accelerated  as  provided  in ss.2.7 or ss.8.1  hereof,  the
outstanding  principal  balance  of the  Note  shall  be  repaid  in 23  monthly
installments,  each in the amount of the  greater of (i) 1.75% of the  Revolving
Credit Loans  outstanding  at the Revolver  Termination  Date or (ii) 90% of the
aggregate  lease payments  received in respect of items of Collateral  which are
subject  to lease  during the  specified  month and a final  installment  in the
amount of the unpaid  balance of the Revolving  Credit Loans  outstanding at the
end of the 24th month  following the Revolver  Termination  Date. In addition to
the monthly  payments  described above, if any payment is required to be made in
order to remain in compliance with the Borrowing Base covenant in ss.7.5 herein,
such additional  payment shall reduce the final  installment  only and shall not
have any effect on the 23 monthly installments.  The term "Agreement Year" shall
mean a one  year  period  ending  on the  same  month  and  day as the  Revolver

                                                                   Dated

Termination  Date. The first Agreement Year will expire on the first anniversary
of the date of this Agreement.

         Willis may have Revolving Credit Loans outstanding at any time and from
time to time in an aggregate amount up to, but not exceeding  $5,000,000 for the
acquisition of Category B Equipment. Any item of Category B Equipment which is a
Stage III jet engine shall be deducted from Category B Equipment and become part
of  Category A  Equipment  upon the  physical  removal of that  engine  from its
airframe,  provided  that such  Equipment  otherwise  qualifies  as  Category  A
Equipment.

         2.2.  Standby Letters of Credit.  The Bank, under the terms and subject
to the conditions of this Agreement, agrees to provide Standby Letters of Credit
to  Willis,  from  time to time  prior  to the  Revolver  Termination  Date,  as
requested by Willis,  provided that (A) the aggregate  amount of Standby Letters
of Credit outstanding at any one time shall not exceed $2,000,000 or such lesser
amount,  if any, as will, when added to the amount of the Revolving Credit Loans
then  outstanding,  aggregate  $15,000,000  (or such lesser  amount as Willis is
entitled to borrow  hereunder  at such time by reason of the  limitation  of the
Borrowing Base or otherwise), and (B) no Standby Letter of Credit shall be for a
term longer than one year.

         Willis  shall  request a Standby  Letter  of  Credit  by  delivering  a
completed  letter  of  credit  application  to the  Bank on such  form as may be
specified  by the Bank not  less  than  three  Business  Days  prior to the date
specified  by Willis as the date the  Standby  Letter of Credit is to be issued.
The standard form of  CoreStates'  letter of credit  application as currently in
effect shall be used.

         Standby  Letters of Credit shall not bear interest until drawn upon but
shall each be subject to an annual charge, payable in advance, as such may exist
from time to time,  provided,  however,  that at no time shall the annual charge
for any Standby Letter of Credit exceed 2.75%.

         Any  obligation of Willis to pay money in  connection  with any Standby
Letter of Credit or the application  therefor shall be deemed secured as if made
as a Loan  hereunder.  In the event Willis shall  terminate  the  Commitment  as
provided  in  ss.2.6  and  shall  pay the  outstanding  principal  amount of the
Revolving  Credit Loans in full and with  interest or the  Revolver  Termination
Date shall  occur at a time when one or more  Standby  Letters of Credit  remain
outstanding, then Willis shall furnish to the Bank within two Business Days such
amount of cash, to be held as cash  collateral and invested in  certificates  of
deposit of the Bank with  interest  payable to Willis,  as will pay the  maximum
amount  which  may be  drawn by  beneficiaries  of  Standby  Letters  of  Credit
outstanding at the date of such termination or the Revolver Termination Date, as
applicable.

         2.3. The Revolving  Credit Note. The Revolving Credit Loans made by the
Bank shall be evidenced by a single  promissory note of Willis (such  promissory
note as it may be amended, extended, modified,  restated, replaced,  substituted
for or renewed,  the "Revolving  Credit Note") in principal face amount equal to
the  Bank's  Revolving  Loan  Commitment,  payable  to the order of the Bank and
otherwise in the form attached  hereto as Exhibit A. The  Revolving  Credit Note
shall be dated the Closing  Date,  shall bear interest at the rate per annum and
be payable as to principal  and interest in  accordance  with the terms  hereof.
Each  outstanding  Revolving  Credit  Loan shall be and  payable as set forth in
ss.2.1  hereof unless the maturity of said Loans is  accelerated  as provided in
ss.2.7 or ss.8.1 hereof.  The Bank shall maintain records of all Loans evidenced
by the Revolving Credit Notes and of all payments  thereon,  which records shall
be conclusive absent manifest error

                                                                   Dated

        2.4. Funding Procedures

         (a)  Requests  for  Advance.  Each request for a Loan shall be made not
later than 2:00 p.m.  on a  Business  Day by  delivery  to the Bank of a written
request  signed by Willis or in the  alternative  a telephone  request  followed
promptly by written confirmation of the request, specifying the date, amount and
type of the Loan to be made.  Each  request  shall be received not less than one
Business Day prior to the date of the proposed  borrowing.  No request  shall be
effective until actually received in writing by the Bank. Willis may not request
more than three advances per week.

         (b)  Irrevocability.  Upon  receipt of a request  for a Loan and if the
conditions  precedent  provided  herein  shall be  satisfied at the time of such
request, the request for a Loan shall not be revocable by Willis.

         (c)  Availability of Funds.  In the case of a borrowing,  the Bank will
make funds immediately  available to Willis on the date of each Loan by a credit
to the account of Willis at the Bank's  address set forth  opposite  its name on
the signature page hereof.

        2.5.  Interest.  Each Loan shall bear interest on the  principal  amount
thereof from the date made until such Loan is paid in full,  at a rate per annum
equal to the Prime Rate plus 1/2 of 1%.

        2.6.  Fees.

         (a)  Structuring  and Arranging Fee. Willis agrees to pay to the Bank a
structuring  and  arranging  fee (the  "Fee") in the  amount of 1/2 of 1% of the
Revolving  Loan  Commitment at the time this Agreement is executed and delivered
by both parties.  The $10,000 deposit paid to the Bank by Willis in March,  1997
shall be credited in full to the amount due with respect to the Closing Fee.

         (b) Revolving Loan  Commitment Fee. Willis agrees to pay to the Bank as
compensation  for the Revolving  Loan  Commitment,  a fee (the  "Revolving  Loan
Commitment Fee") computed as follows:  (1) when the average daily balance of the
aggregate Loans  outstanding  under the Revolving Credit Note (measured over the
previous calendar quarter or portion thereof, as applicable) is less than 50% of
the Revolving Loan Commitment,  Willis shall pay a Revolving Loan Commitment Fee
equal to 3/8 of 1% of the unused portion of the Revolving Loan  Commitment,  and
(2) when the average daily balance of the aggregate Loans  outstanding under the
Revolving  Credit Note (measured over the previous  calendar  quarter or portion
thereof, as applicable) is at least 50% of the Revolving Loan Commitment, Willis
shall pay a  Revolving  Loan  Commitment  Fee  equal to 1/4 of 1% of the  unused
portion of the Revolving  Loan  Commitment.  The Revolving  Loan  Commitment Fee
shall be payable in arrears on the first day of each  January,  April,  July and
October,  commencing July 1, 1997 (for the three month period or portion thereof
ended on the preceding  day), and ending on the Revolver  Termination  Date. The
Revolving  Loan  Commitment  Fee shall be  calculated  on the basis of a 360 day
year.

        2.7. Reduction or Termination of Commitments.

         (a)  Voluntary.  Willis may at any time,  on not less than one Business
Days'  written  notice,  terminate  or  permanently  reduce the  Revolving  Loan
Commitment,  provided  that any  reduction  shall be

                                                                   Dated

in the  minimum  amount  of  $150,000  or a  multiple  thereof  and that no such
reduction  shall cause the principal  amount of Loans  outstanding to exceed the
reduced Revolving Loan Commitment.

         (b) Revolving Loan Commitment  Termination.  In the event the Revolving
Loan  Commitment  is  terminated,   the  Revolver   Termination  Date  shall  be
accelerated  to the date of such  termination  and Willis shall,  simultaneously
with such  termination,  repay the  Revolving  Credit Loans in  accordance  with
ss.2.9.

        2.8  Voluntary  Prepayments.  On one Business  Day's notice to the Bank,
Willis may, without penalty, at its option, prepay any Loan in whole at any time
or in part from time to time,  provided that each partial prepayment shall be in
the minimum  principal  amount of $150,000  or, if  greater,  then in  multiples
thereof and, if less than $150,000  shall be  outstanding,  in principal  amount
equal  to  amount   remaining   outstanding.   Notwithstanding   the  foregoing,
prepayments may be made in connection with the release of collateral as provided
in ss.9.3,  which  prepayments  shall not be subject to the  requirements of the
previous sentence.

        2.9. Payments.

payable on the first  Business Day of each calendar  month and upon the Revolver
Termination Date.

         (b) Form of Payments,  Application of Payments, Payment Administration,
Ect. All payments of principal,  interest,  fees,  or other  amounts  payable by
Willis hereunder shall be remitted to the Bank at the address set forth opposite
its name on the  signature  page hereof or at such office or account as the Bank
shall specify to Willis, in immediately available funds not later than 2:00 p.m.

a Business  Day,  the  maturity  of such  payment  shall be extended to the next
succeeding  Business  Day and  interest and  commitment  fees shall  continue to
accrue  during such  extension.  Willis  authorizes  the Bank to deduct from any
account of Willis  maintained at the Bank or over which the Bank has control any
amount payable under this  Agreement,  the Note or any other Loan Document which
is not  paid in a timely  manner.  The  Bank's  failure  to  deliver  any  bill,
statement or invoice with respect to amounts due under this Section or under any
Loan Document  shall not affect  Willis's  obligation to pay any  installment of
principal,  interest  or any other  amount  under  this  Agreement  when due and
payable.

         (c) Demand Deposit  Account.  Willis shall maintain at least one demand

the Bank to deposit  into said  account  all  amounts to be  advanced  to Willis
hereunder.  Further,  Willis  authorizes  the Bank  (but the Bank  shall  not be
obligated)  to deduct from said  account,  or any other  account  maintained  by
Willis at the Bank, any amount payable hereunder on or after the date upon which
it is due and payable.  Such  authorization  shall include but not be limited to
amounts payable with respect to principal, interest, fees and expenses.

         (d) Net Payments.  All payments  made to the Bank by Willis  hereunder,
under any Note or under any other Loan  Document  will be made  without set off,
counterclaim or other defense.

                                                                   Dated

validly  existing and in good standing under the laws of the jurisdiction of its
incorporation,  (ii) has the corporate power and authority  necessary to own its
assets,  carry on its  business  and  enter  into and  perform  its  obligations

qualified to do business and is in good standing in each jurisdiction  where the
nature  of  its  business  or the  ownership  of its  properties  requires  such
qualification,  except  where the  failure to be so  qualified  would not have a
Material Adverse Effect.

        3.2. Corporate Authority,  Validity,  Etc. The making and performance of
the Loan Documents to which it is a party are within its power and authority and
have been duly  authorized by all  necessary  corporate  action.  The making and
performance  of the Loan Documents do not and under present law will not require

other  person,  do not and under  present law will not  violate  any law,  rule,
regulation order, writ, judgment, injunction, decree, determination or award, do
not violate any provision of its charter or by-laws,  do not and will not result
in any breach of any material  agreement,  lease or  instrument to which it is a

are  accurately  set forth on  Schedule 1 attached  hereto;  all such shares are
validly issued, fully paid and non-assessable, and the issuance and sale thereof
are in compliance  with all  applicable  federal and state  securities and other

lease or instrument except to the extent such default  reasonably could not have
a Material Adverse Effect. No  authorizations,  approvals or consents of, and no
filings or  registrations  with,  any  governmental  or regulatory  authority or
agency are necessary for the execution, delivery or performance by Willis of any
Loan  Document  to  which it is a party or for the  validity  or  enforceability
thereof,  except any filings or registrations expressly contemplated by the Loan
Documents.  Each Loan Document, when executed and delivered,  will be the legal,
valid and binding  obligation  of Willis,  enforceable  against it in accordance
with its terms.

        3.3.  Litigation.  Except  as  disclosed  on  Schedule  1,  there are no
actions,  suits or  proceedings  pending or, to Willis's  knowledge,  threatened
against or affecting  Willis or any of its assets  before any court,  government
agency, or other tribunal which if adversely determined  reasonably could have a
Material  Adverse Effect or upon the ability of Willis to perform under the Loan
Documents.  If there is any disclosure on Schedule 1, the status  (including the
tribunal,  the nature of the claim and the amount in  controversy)  of each such
litigation matter as of the date of this Agreement is set forth in Schedule 1.

or contributes to or has maintained or contributed to any multiemployer plan (as
defined in ss.4001 of ERISA)  under which  Willis or any ERISA  Affiliate  could
have any  withdrawal  liability;  (b)  neither  Willis nor any ERISA  Affiliate,
sponsors  or  maintains  any Plan under which  there is an  accumulated  funding
deficiency within the meaning of ss.412 of the Code,  whether or not waived; (c)
the aggregate  liability for accrued benefits and other ancillary benefits under
each  Plan that is or will be  sponsored  or  maintained  by Willis or any ERISA
Affiliate (determined on the basis of the actuarial

                                                                   Dated

assumptions  prescribed for valuing benefits under  terminating  single-employer
defined  benefit  plans under  Title IV of ERISA) does not exceed the  aggregate
fair market value of the assets under each such defined  benefit  pension  Plan;
(d) the aggregate liability of Willis and each ERISA Affiliate arising out of or
relating to a failure of any Plan to comply with the  provisions of ERISA or the
Code, will not have a Material Adverse Effect;  and (e) there does not exist any
unfunded liability (determined on the basis of actuarial assumptions utilized by
the actuary for the plan in preparing the most recent  Annual  Report) of Willis
or any  ERISA  Affiliate  under  any  plan,  program  or  arrangement  providing
post-retirement life or health benefits.

        3.5.  Financial  Statements.  The consolidated  financial  statements of
Willis as of and for the Fiscal Years ending  December 31, 1996 and December 31,
1995,  consisting of a balance sheet, a statement of operations,  a statement of
shareholders' equity, a statement of cash flows and accompanying footnotes,  and
the interim consolidated and consolidating  financial statements of Willis as of
March 31, 1997 furnished to the Bank in connection herewith,  present fairly, in
all  material  respects,  the  financial  position,  results of  operations  and
operating  statistics Willis as of the dates and for the periods referred to, in
conformity  with GAAP.  Except as set forth on  Schedule 1 hereto,  there are no
liabilities,  fixed or  contingent,  which are not  reflected in such  financial
statements,  other than  liabilities  which are not  required to be reflected in
such balance sheets.

        3.6.  Not in Default,  Judgments,  Etc. No Event of Default or Potential
Default  under any Loan  Document  has occurred  and is  continuing.  Willis has
satisfied  all  judgments  and is not in default with  respect to any  judgment,
writ,  injunction,  decree,  rule, or regulation  of any court,  arbitrator,  or
federal, state, municipal,  or other governmental authority,  commission,  board
bureau, agency, or instrumentality, domestic or foreign.

        3.7 Taxes.  Willis has filed all federal,  state,  local and foreign tax
returns  and  reports  which it is  required  by law to file and as to which its
failure to file would have a Material  Adverse  Effect,  and has paid all taxes,
including wage taxes,  assessments,  withholdings and other governmental charges
which are  presently due and payable,  other than those being  contested in good
faith by appropriate  proceedings,  if any, and disclosed on Schedule 1. The tax
charges,  accruals  and  reserves on the books of Willis are adequate to pay all
such taxes that have accrued but are not presently due and payable.

        3.8.  Permits,  Licenses,  Etc. Willis possesses all permits,  licenses,
franchises,  trademarks,  trade names,  copyrights and patents  necessary to the
conduct of its  business as presently  conducted or as presently  proposed to be
conducted,  except  where  the  failure  to  possess  the same  would not have a
Material Adverse Effect.

        3.9. No Materially Adverse Contracts, Etc. To the best of its knowledge,
Willis is not subject to any charter,  corporate or other legal restriction,  or
any judgment,  decree,  order,  rule or regulation  which in the judgment of its
directors  or officers  has or is  expected  in the future to have a  materially

shall provide that CoreStates shall retain the sole right and  responsibility to
