                            SHARE PURCHASE AGREEMENT

      This Share Purchase Agreement is made as of November 7, 2000 by and
between SR Technics Group America, Inc., a Delaware corporation ("Buyer"), and
Willis Lease Finance Corporation, Inc., a Delaware corporation ("Seller").

                              PRELIMINARY STATEMENT

      Seller desires to sell, and Buyer desires to purchase, all of the
outstanding shares (the "Shares") of Willis Aeronautical Services, Inc., a
California corporation, and a wholly-owned subsidiary of Seller (the "Company"),
on the terms set forth in this Agreement.

                                    AGREEMENT

      The parties, intending to be legally bound, agree as follows:

                                  1. ARTICLE 1

                          DEFINITIONS AND USE OF TERMS

1.1 CONSTRUCTION

      Any reference in this Agreement to an "Article," "Section" or "Part"
refers to the corresponding Article, Section and Part of this Agreement or the
Disclosure Schedule, unless the context indicates otherwise. The headings of
Articles and Sections are provided for convenience only and should not affect
the construction or interpretation of this Agreement. All words used in this
Agreement should be construed to be of such gender or number as the
circumstances require. The terms "include" or "including" indicate examples of a
foregoing general statement and not a limitation on that general statement. Any
reference to a statute refers to the statute, any amendments or successor
legislation, and all regulations promulgated under or implementing the statute,
as in effect at the relevant time. Any reference to a Contract or other document
as of a given date means the Contract or other document as amended, supplemented
and modified from time to time through such date.

1.2 DEFINITIONS

      For the purposes of this Agreement, the capitalized terms and variations
on them have the meanings specified in Schedule 1.2.

                                    ARTICLE 2

                      SALE AND TRANSFER OF SHARES; CLOSING

2.1 SHARES

      Subject to the terms and conditions of this Agreement, at the Closing,
Seller will sell and transfer the Shares to Buyer, and Buyer will purchase the
Shares from Seller.

2.2 PURCHASE PRICE

                                       6
<PAGE>

      Subject to the post-closing adjustments paid pursuant to Section 2.6, the
purchase price for the Shares (the "Purchase Price") will be the Estimated
Adjusted Net Book Value, plus the Estimated Closing Date Inventory Value, plus
U.S.$2,500,000 (the "Initial Purchase Price").

2.3 CLOSING

      The Closing will take place at the offices of the Seller within five
business days of the satisfaction or waiver of each of the conditions set forth
in Articles 7 and 8 or at such other time and place as the parties mutually
agree. Subject to the provisions of Article 9, failure to consummate the
purchase and sale provided for in this Agreement at the place and on the date
determined by the previous sentence will result in the termination of this
Agreement and will relieve each party of any obligation under this Agreement.

2.4 CLOSING DELIVERIES

      At the Closing:

      (a) Seller will deliver to Buyer:

            (i) certificates representing the Shares, duly endorsed in blank (or
      accompanied by duly executed stock powers in blank);

            (ii) a pay-off letter from First Union National Bank with respect to
      the amount owed to such bank by Company pursuant to the Revolving Credit
      Agreement in the form attached hereto as Exhibit A; and

            (iii) a certificate executed by the chief executive officer of
      Seller representing and warranting to Buyer that each of Seller's
      representations and warranties in this Agreement was accurate in all
      respects as of the date of this Agreement and is accurate in all respects
      as of the Closing Date as if then made (giving full effect to any
      supplements to the Disclosure Schedule that Seller delivered to Buyer
      before the Closing Date in accordance with Section 5.5).

      (b) Buyer will deliver to Seller:

            (i) the Initial Purchase Price by wire transfer to an account
specified by Seller;

            (ii) a certificate executed by the chief executive officer of Buyer
to the effect that, except as otherwise stated in such certificate, each of
Buyer's representations and warranties in this Agreement was accurate in all
respects as of the date of this Agreement and is accurate in all respects as of
the Closing Date as if then made; and

            (iii) a certificate executed by the chief executive officer of SR
Technics Group, a company organized under the laws of Switzerland ("SRT") to the
effect that, except as otherwise stated in such certificate, each of SRT's
representations and warranties in this Agreement was accurate in all material
respects as of the date of this Agreement and is accurate in all material
respects as of the Closing Date as if then made.

                                       7

2.5 INVENTORY VALUATION

      The Inventory as of May 31, 2000 ("May 31 Inventory") has an agreed to
value of U.S.$15,000,000 (the "Initial Inventory Value"). The Inventory value
will be calculated as of the Closing Date according the rules listed below:

      (a) If material was May 31 Inventory and was sold prior to the Closing
Date (the "Sold Inventory"), the "Sold Inventory Valuation Adjustment" will be
calculated as follows: the Sold Inventory Valuation Adjustment is equal to the
(i) sales price less (I) any repair and overhaul expenses incurred after May 31,
2000 and less (II) any gross profit margin of the Sold Inventory multiplied by
(ii) the corresponding Valuation Percentage, as listed on Schedule 2.5. The May
31 Inventory that remains in the Inventory on the Closing Date will not affect
the Sold Inventory Valuation Adjustment.

      (b) If new Inventory has been purchased between June 1, 2000 and the
Closing Date, and is still in the Inventory as of the Closing Date (the "New
Inventory"), any increase in the value of the total Inventory (the "New
Inventory Valuation Adjustment") will be calculated as follows: the New
Inventory Valuation Adjustment will be equal to the net book value of the New
Inventory as of the Closing Date. Only JT8D spare parts will be counted in the
New Inventory. No other spare parts will be considered New Inventory. Any
Inventory purchased and sold between June 1, 2000 and the Closing Date will not
be factored into the calculation of the New Inventory Valuation Adjustment.

      (c) If the Company incurs any repair and overhaul expenses between June 1,
2000 and the Closing Date which are directly attributable to May 31 Inventory or
New Inventory, the cost of these expenses, excluding the amount attributable to
Sold Inventory, will be referred to as the "Repair and Overhaul Valuation
Adjustment".

      (d) The "Closing Date Inventory Value" is the aggregate of (i) the Initial
Inventory Value, minus (ii) any Sold Inventory Valuation Adjustment, plus (iii)
any New Inventory Valuation Adjustment, plus (iv) any Repair and Overhaul
Valuation Adjustment.

2.6 PURCHASE PRICE ADJUSTMENT PROCEDURE

      (a) The "Adjustment Amount" (which may be a positive or negative number)
will be equal to (i) Adjusted Net Book Value, plus the Closing Date Inventory
Value plus U.S.$2,500,000 minus (ii) the Initial Purchase Price. "Adjusted Net
Book Value" means the amount calculated by subtracting the book value of the
liabilities (excluding the Company's debt to Seller and affiliates) as of the
Closing Date from the book value of the Company's assets (excluding the net book
value of Inventory (including aircraft engines that are part of Inventory)) as
of the Closing Date.

      (b) Buyer will cause the Company to prepare a statement of the Adjusted
Net Book Value and Closing Date Inventory Value as of the Closing Date (the
"Adjusted Statement"). The Adjusted Net Book Value will be determined consistent
with the accounting policies and procedures used in the preparation of the
Company May 31 Balance Sheet. Buyer will cause the Adjusted Statement to be
audited by independent public accountants. Buyer will deliver the Adjusted
Statement and the proposed Adjustment Amount to Seller within 60 days after the
Closing Date. If within 30 days following delivery of the Adjusted Statement,
Seller does not deliver to Buyer notice of any objection to the

                                       8
<PAGE>

Adjusted Statement (which notice must contain a reasonably detailed statement of
the basis of Seller's objection), then the Adjustment Amount will be paid under
Section 2.6(f).

      (c) If Seller disputes any items of the Adjusted Statement, then Seller
will deliver to Buyer, within 30 days following Seller's receipt of the Adjusted
Statement, a written notice specifying in reasonable detail all disputed items
and the basis for such disputed items (a "Notice of Dispute"). If Seller
delivers a Notice of Dispute, Buyer and Seller will, within 30 days following
such notice (the "Resolution Period"), attempt in good faith to resolve their
differences, and any resolution by them as to any disputed amounts will be in
writing, and will be final, binding and conclusive.

      (d) If the parties are unable to resolve all disputes with respect to the
Adjusted Statement prior to the expiration of the Resolution Period, issues
remaining in dispute will be submitted, as soon as practicable (but no later
than 30 days from the expiration of the Resolution Period), to public
accountants of internationally recognized standing mutually acceptable to the
parties that are not the regular accounting firm of either party (the "Neutral
Auditors"). Each party will furnish to the Neutral Auditors such work papers and
other documents and information relating to the disputed issues as the Neutral
Auditors may request and are available to that party (or its independent public
accountants), and will be afforded the opportunity to present the Neutral
Auditors any material relating to the disputed issues and to discuss the issues
with the Neutral Auditors. The parties agree to execute a reasonable engagement
letter if requested by the Neutral Auditors. The Neutral Auditors will act as an
expert and not as an arbitrator to determine only those issues with respect to
the Adjusted Statement which are still in dispute. The Neutral Auditors'
determination will be made as soon as practicable after their selection, will be
set forth in a written statement (the "Neutral Auditors' Notice") delivered to
Buyer and Seller and will be final, binding and conclusive and enforceable in
any court of competent jurisdiction. The fees and expenses of the Neutral
Auditors will be allocated by the Neutral Auditors between Buyer and Seller in
proportion to the extent that either party did not prevail on its items in
dispute; provided that so long as a party complies in all material respects in
good faith with the procedures of this Section 2.6, such fees will not include
the other party's outside counsel or accounting fees.

      (e) The Neutral Auditors will recalculate the Adjustment Amount based on
the resolution of the issues in dispute.

      (f) On the tenth business day following (i) the expiration of the 30-day
period for delivery of a Notice of Dispute (if no Notice of Dispute is given and
subject to Section 2.6(c)), (ii) Buyer's and Seller's resolution of all
objections pursuant to Section 2.6(c), or (iii) the date of the Neutral
Auditors' Notice (as the case may be), if the Adjustment Amount is positive,
Buyer will pay that amount to Seller, and if the Adjustment Amount is negative,
Seller will pay the absolute value of that amount to Buyer, in accordance with
the terms of this Section 2.6(f). All payments will be made by wire transfer to
an account specified by the recipient, together with interest at the prime rate
(as published in The Wall Street Journal on the Closing Date), compounded daily
beginning on the Closing Date and ending on the date of payment.

      (g) The parties agree that no party will be deemed to be in breach of or
default under this Agreement by reason of such party's technical failure to meet
any of the timetables for performance specified in this Section 2.6, provided
that such party will have made a good faith effort to meet such timetables and
otherwise will have complied and will continue to comply in all material
respects with the other provisions of this Section 2.6.

                                    ARTICLE 3

                    REPRESENTATIONS AND WARRANTIES OF SELLER

      Subject to the Disclosure Schedule, which may be updated pursuant to
Section 5.5, Seller represents and warrants to Buyer as follows:

3.1 ORGANIZATION AND GOOD STANDING

      (a) The Company is a corporation duly organized, validly existing and in
good standing under the laws of its jurisdiction of formation, with full
corporate power and authority to conduct its business as it is now being
conducted, to own or use the properties and assets that it purports to own or
use, and to perform all its obligations under all Company Contracts. The Company
is duly qualified to do business as a foreign entity and is in good standing in
each jurisdiction in which either the ownership or use of the properties owned
or used by it, or the nature of the activities conducted by it, requires such
qualification, except where the failure to be so qualified or be in good
standing will not have a Material Adverse Effect.

      (b) Seller has delivered to Buyer copies of the Organizational Documents
of the Company, as currently in effect. Part 3.1 contains a complete and
accurate listing of the Company's jurisdiction of formation and other
jurisdictions in which it is authorized to do business.

3.2 ENFORCEABILITY; NO CONFLICT

      (a) Seller is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware. Assuming due authorization,
execution and delivery of this Agreement by Buyer, this Agreement constitutes
the legal, valid, and binding obligation of Seller, enforceable against Seller
in accordance with its terms, subject to any applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws now or hereafter in effect relating
to creditors' rights generally or to general principles of equity. Assuming due
authorization, execution and delivery by the other parties thereto, each
Ancillary Agreement and Transaction Document to which Seller is a party will,
upon execution and delivery, constitute Seller's legal, valid, and binding
obligation, enforceable against Seller in accordance with its terms, subject to
any applicable bankruptcy, insolvency, reorganization, moratorium or similar
laws now or hereafter in effect relating to creditors' rights generally or to
general principles of equity. Seller has the absolute and unrestricted right,
power, and authority to execute and deliver this Agreement and the Ancillary
Agreements and Transaction Documents to which it is a party and to perform its
obligations hereunder and thereunder, which actions have been duly authorized
and approved by all necessary corporate action of Seller.

      (b) Except for requirements under the HSR Act or as otherwise disclosed in
Part 3.2(b), Seller and the Company are not and will not be required to give any
notice to any Person or obtain any material Consent or material Governmental
Authorization in connection with the execution and delivery of this Agreement or
the consummation or performance of any of the Contemplated Transactions.

                                       10
<PAGE>

      (c) Except as disclosed in Part 3.2(c), neither the execution and delivery
of this Agreement nor the consummation or performance of any of the Contemplated
Transactions will directly or indirectly (with or without notice or lapse of
time):

            (i) Contravene any provision of the Organizational Documents of the
      Company, or any resolution adopted by the management or shareholders of
      the Company;

            (ii) Contravene any material provision or term of any Company
      Contract, Governmental Authorization, material Legal Requirement, or Order
      to which the Company, or any of the assets owned or used by the Company,
      may be subject; or

            (iii) result in the imposition or creation of any Encumbrance (other
      than in favor of Buyer) upon or with respect to any of the assets owned or
      used by the Company.

      (d) Except as disclosed in Part 3.2(d), neither the execution and delivery
of this Agreement by Seller nor the consummation or performance of any of the
Contemplated Transactions by Seller will give any Person the right to prevent,
delay, or otherwise interfere with any of the Contemplated Transactions pursuant
to:

            (i) any provision of Seller's Organizational Documents;

            (ii) any resolution adopted by the board of directors or the
stockholders of Seller;

            (iii) any material Legal Requirement or Order to which Seller may be
subject; or

            (iv) any material provision or term of any Contract to which Seller
is a party or by which Seller may be bound.

3.3 CAPITALIZATION

      The authorized equity securities of the Company consist of 100,000 shares
of common stock, no par value, of which 12,500 shares are issued and
outstanding. The Shares represent all of the issued and outstanding shares in
the Company. Seller is and will be on the Closing Date the record and beneficial
owner and holder of the Shares, free and clear of all Encumbrances, except for
the liens of Union Bank of California and Bank of America and the liens of the
banks pursuant to the Revolving Credit Agreement which shall be released on
closing. No legend (other than legends required by applicable federal and state
securities laws) or other reference to any purported Encumbrance appears upon
any certificate representing the Shares. All of the Shares have been duly
authorized and validly issued and are fully paid and nonassessable. There are no
Contracts giving any Person any right, title or interest in or to the Shares,
any equity securities or other securities of the Company. None of the Shares or
other securities of the Company was issued in violation of any Legal
Requirement. The Company does not own, or have any Contract to acquire, any
equity securities or other securities of any Person or any direct or indirect
equity or ownership interest in any other business.

3.4 FINANCIAL STATEMENTS

                                       11
<PAGE>

      Seller has delivered to Buyer the following (collectively referred to as
the "Financial Statements"): (a) the unaudited balance sheet of the Company at
December 31, 1999 (the "Company's 1999 Balance Sheet") and (b) an unaudited
balance sheet of the Company as at May 31, 2000 (the "Company May 31 Balance
Sheet") and the related unaudited statement of income. The Financial Statements
have been prepared in accordance with the books and records of the Company and
fairly present the financial condition and the results of operations, changes in
stockholders' and members' equity, and cash flow of the Company as at the
respective dates of and for the periods referred to in such Financial
Statements, all in accordance with GAAP, except as otherwise noted in the notes
or schedules, subject in the case of interim or unaudited financial statements,
to normal recurring year-end adjustments (the effect of which will not,
individually or in the aggregate, be materially adverse to the financial
condition of the Company). Except as set forth in Part 3.4, the Financial

this Agreement. In addition, the provisions of this Agreement, in particular

this Agreement has been committed by the other party or parties and such breach
has not been waived in writing by the other party or parties;

      (b) by Buyer if any condition in Article 7 has not been satisfied as of

      (c) by Seller, if any condition in Article 8 has not been satisfied as of

obligations under this Agreement or because one or more of the conditions to the

under this Agreement, the terminating party's right to pursue all legal remedies
will survive such termination unimpaired; provided, further, that the sole

through a supplemental disclosure by the other party or otherwise) that a
representation or warranty made by the other party is untrue will be to elect to
terminate this Agreement pursuant to Section 9.1.

                            INDEMNIFICATION; REMEDIES

this Agreement, will survive the Closing and the consummation of the
Contemplated Transactions, subject to the limitations set forth in this Section
10.1 and Sections 10.4, 10.5 and Article 11. The right to indemnification,
payment of damages or other remedy based on such representations, warranties,
covenants, and obligations will not be affected by any investigation conducted
with respect to the accuracy or inaccuracy of or compliance with, any
representation, warranty, covenant, or obligation, except to the extent that a
party obtains actual knowledge of an inaccuracy of, or failure of the other
party to comply with any representation, warranty, covenant or obligation. The
sole remedy of any party which obtains actual knowledge prior to the Closing
(whether through a supplemental disclosure by the other party or otherwise),
that a representation or warranty made by the other party is untrue, will be to
elect to terminate this agreement pursuant to Section 9.1. Notwithstanding any
other provision of this Agreement to the contrary (except as relates to Tax
matters governed by Article 11), the provisions of this Article 10 will be the
sole and exclusive remedy from and after the Closing Date for any claims arising
under this Agreement, including claims of breach of any representation, warranty
or covenants in this Agreement; provided, however, that the foregoing clause of
this sentence will not be deemed a waiver by any party of any right to specific
performance or injunctive relief, or any right to remedy arising by reason of
any claim of fraud with respect to this Agreement.

      Subject to Sections 10.4 and 10.5, Seller will indemnify and hold harmless
Buyer, the Company, and their respective Representatives, equity owners,

certificate or document delivered by Seller pursuant to this Agreement;

      (d) any breach by Seller of any covenant or obligation of Seller in this

Sheet;

      (f) any matter disclosed in Part 3.22;

      (g) any claim by any Person for brokerage or finder's fees or commissions
or similar payments based upon any agreement or understanding alleged to have
been made by any such Person with either Seller or the Company (or any Person
acting on their behalf) in connection with any of the Contemplated Transactions;

      (h) any and all Proceedings, demands or assessments incidental to any of

Company dated May 1, 2000.

Notwithstanding the foregoing, indemnification for breach of any representation
or warranty contained in Section 3.17 or for breach of any covenant or
obligation contained in Article 11 is governed by Article 11 (except as
expressly set forth in this Article 10).

10.3 INDEMNIFICATION BY BUYER

      Buyer will indemnify and hold harmless Seller and its Representatives,
equity owners, controlling persons and affiliates (collectively, the "Seller
Indemnitees") for, and will pay to the Seller Indemnitees the monetary value of
any Adverse Consequences arising, directly or indirectly, from or in connection
with:

      (a) any breach of any representation or warranty made by Buyer in this
Agreement or in any document (other than the certificate described in Section
2.4(b)(ii)) delivered by Buyer pursuant to this Agreement;

      (b) any breach by Buyer of any covenant or obligation of Buyer in this
Agreement;

      (c) unless a release shall be obtained from the lessor thereunder, any
Liabilities arising under Company Lease Number One or Company Lease Number Two
subsequent to Closing any and all Proceedings, demands or assessments incidental
thereto;

      (e) any and all Proceedings, demands or assessments incidental to any of
the matters set forth in Section 10.3(a) through (d).

performed or complied with before the Closing Date or (ii) a representation or
warranty, other than those in Sections 3.3, 3.17, 3.18, and 3.20, unless on or

of a claim specifying the factual basis of that claim in reasonable detail to
the extent then known by Buyer; a claim with respect to a breach of a
representation or warranty contained in Section 3.3, 3.18, or 3.20, or a claim
for indemnification or reimbursement not based upon any covenant or obligation
to be performed or complied with before the Closing Date, may be made at any

performed or complied with before the Closing Date may be made at any time.

10.5 LIMITATIONS ON INDEMNIFICATION--SELLER

      (b) Notwithstanding any other provision in this Agreement, and in addition
to the limitations set forth above, (i) Seller will have no liability (for
indemnification or otherwise) under Section 10.2 or Article 11 unless and until
the monetary value of the Adverse Consequences suffered by the Buyer
Indemnitees, in the aggregate, exceeds U.S.$200,000, in which event the relevant
Buyer Indemnitees will only be entitled to recover amounts in respect of
Seller's indemnification obligations hereunder that are in excess of
U.S.$200,000, and (ii) Seller's maximum liability to the Buyer Indemnitees
(other than with respect to claims under Article 11), in the aggregate, under
this Agreement shall be the Purchase Price.

      (c) Notwithstanding any other provision in this Agreement, and in addition
to the limitations set forth above, Seller will have no liability pursuant to
this Article 10 and Article 11 with respect to any Liability or Adverse
Consequences suffered by any Buyer Indemnitee to the extent that any Buyer
Indemnitee shall already have obtained (whether pursuant to any other provision

with respect to such Liability or Adverse Consequences from Seller. Without
limiting the foregoing, Seller will have no liability pursuant to this Article

<PAGE>

10.7 PROCEDURE FOR INDEMNIFICATION--DEFENSE OF THIRD-PARTY CLAIMS

      (a) Promptly after receipt by a Person entitled to indemnity under Section
10.2 or 10.3 (an "Indemnified Person") of notice of the assertion of a
third-party claim against it, the Indemnified Person will, if a claim is to be
made against a Person obligated to indemnify under such Section (an
"Indemnifying Person"), give notice to the Indemnifying Person of the assertion
of such claim. An Indemnified Person's failure to notify an Indemnifying Person
will not relieve the Indemnifying Person of any Liability that it may have to
the Indemnified Person, except to the extent that the Indemnifying Person
demonstrates that the resolution of such claim is prejudiced by the Indemnified
Person's failure to give such notice.

      (b) If any claim referred to in Section 10.7(a) is brought against an
Indemnified Person by means of a Proceeding and the Indemnified Person gives
notice to the Indemnifying Person of the commencement of such Proceeding, the
Indemnifying Person will be entitled to participate in such Proceeding and, to
the extent that it wishes (unless (i) the Indemnifying Person is also a party to
such Proceeding and the Indemnified Person determines in good faith that joint
representation would be inappropriate or (ii) the Indemnifying Person fails to
provide reasonable assurance to the Indemnified Person of its financial capacity
to defend such Proceeding and provide indemnification with respect to such
Proceeding), assume the defense of such Proceeding with counsel reasonably
satisfactory to the Indemnified Person. After notice from the Indemnifying
Person to the Indemnified Person of its election to assume the defense of such
Proceeding, the Indemnifying Person will not, as long as it diligently conducts
such defense, be liable to the Indemnified Person under this Article 10 for any
fees of other counsel or any other expenses with respect to the defense of such
Proceeding, in each case subsequently incurred by the Indemnified Person in
connection with the defense of such Proceeding, other than reasonable costs of
investigation. If the Indemnifying Person assumes the defense of a Proceeding,
no compromise or settlement of such claims may be effected by the Indemnifying
Person unless (A) the sole relief provided is monetary damages that are paid in
full by the Indemnifying Person or (B) the Indemnified Person consents to such
compromise or settlement, which such consent will not be unreasonably withheld
or delayed.

                                       39
<PAGE>

      (c) If written notice is given to an Indemnifying Person of the
commencement of any Proceeding and the Indemnifying Person does not, within
fifteen days after the Indemnified Person's notice is given, give written notice
to the Indemnified Person of its election to assume the defense of such
Proceeding, the Indemnifying Person will be bound by any determination made in
such Proceeding or any compromise or settlement effected by the Indemnified
Person.

      (d) Notwithstanding the foregoing, if an Indemnified Person determines in
good faith that there is a reasonable probability that a Proceeding may
adversely affect it or its affiliates other than as a result of monetary damages
for which it would be entitled to indemnification under this Agreement, the
Indemnified Person may, by notice to the Indemnifying Person, assume the
exclusive right to defend, compromise, or settle such Proceeding (unless the
Indemnifying Person is also a party to such Proceeding and the Indemnifying
Person determines in good faith that joint representation would be
inappropriate), but the Indemnifying Person will not be bound by any
determination of a Proceeding so defended or any compromise or settlement
effected without its consent (which may not be unreasonably withheld).

      (e) Notwithstanding the provisions of Sections 10.7(a) through (d), any
claim involving Taxes will be governed by Article 11.

10.8 PROCEDURE FOR INDEMNIFICATION--OTHER CLAIMS

      A claim for indemnification for any matter not involving a third-party
claim may be asserted by notice to the party obligated to indemnify and shall be
paid promptly after such notice.

                                   ARTICLE 11

                                   TAX MATTERS

11.1 TAX RETURNS

      (a) Seller will prepare and file, or cause to be prepared and filed, all
of the Company's Tax Returns for all taxable years or periods ending on or
before the Closing Date, and Seller will pay, or cause to be paid, all Taxes
shown as due thereon, (and will be entitled to all refunds thereof) except to
the extent such Taxes are taken into account in the calculation of the Closing
Net Book Value. Seller will prepare, or cause to be prepared, such Tax Returns
using accounting methods and other practices that are consistent with those used
by the Company in its prior Tax Returns. Items to be taken into account in the
Company's Tax Return for the short taxable period ending on the Closing Date
will be determined under the "closing-the-books" method as described in Treasury
Regulation Section 1.1502-76(b)(2)(i) (or any similar provision of state, local
or foreign law). Seller will deliver, or cause to be delivered, a draft of each
of the Tax Returns for the Company to Buyer not less than 75 days prior to the
due date for filing such Tax Returns, and Buyer will provide Seller with its
comments on, and proposed changes to, such Tax Returns not later than 45 days
prior to such due date. If any aspect of such Tax Returns remains in dispute
within 30 days prior to the due date for filing such Tax Returns, the matter in
dispute will be submitted to a mutually acceptable, nationally-recognized firm
of certified public accountants for resolution. The decision of such accountant
will be final and binding on the parties, and the fees and expenses of the
accountant will be paid one-half by Buyer and one-half by Seller.

                                       40
<PAGE>

      (b) Buyer will prepare and file, or cause to be prepared and filed, all of
the Company's Tax Returns for all taxable years or periods ending after the
Closing Date, and Buyer will pay, or cause to be paid, all Taxes shown as due
thereon; provided, that with respect to any Straddle Period, Buyer will be
entitled to indemnification as set forth in Section 11.3.

11.2 INDEMNIFICATION OF SELLER

      Buyer will indemnify and hold harmless Seller from and against any and all
Taxes arising out of or relating to any breach of Buyer's covenants contained in
this Article 11.

11.3 INDEMNIFICATION OF BUYER

      Seller will indemnify and hold harmless the Buyer Indemnitees from and
against any and all Liability of the Company for Taxes arising out of or
relating to: (a) the Pre-Closing Period that have not been paid prior to the
Closing Date and are not taken into account in the calculation of the Closing
Net Book Value; (b) any member of an affiliated group with which the Company has
filed a Tax Return on a consolidated, combined or unitary basis; and (c) any
Adverse Consequences arising, directly or indirectly, from or in connection with
any breach of the representations and warranties contained in Section 3.17 of
this Agreement or of Seller's covenants contained in this Article 11.

11.4 APPORTIONMENT OF TAXES

      With respect to any Straddle Period, Buyer and Seller will, to the extent
permitted by law, elect to treat the Closing Date as the last day of the taxable
year or period of the Company and will apportion any Taxes arising in a Straddle
Period to the Pre-Closing Period under the "closing-the-books" method as
described in Treasury Regulation Section 1.1502-76(b)(2)(i) (or any similar
provision of state, local or foreign law). In any case where applicable law does
not permit the Company to treat the Closing Date as the last day of the taxable
year or period, any Taxes arising in a Straddle Period will be apportioned to
the Pre-Closing Period and the period beginning after the Closing Date based on
a closing of the books of the Company; provided that (i) exemptions, allowances
or deductions that are calculated on an annualized basis (including
depreciation, amortization and depletion deductions) will be apportioned on a
daily pro rata basis and (ii) solely for purposes of determining the marginal
tax rate applicable to income during such period in a jurisdiction in which such
tax rate depends upon the level of income, annualized income will be taken into
account.

11.5 INDEMNIFICATION PROCESS

      Buyer will notify Seller in writing ("Buyer's Notice") promptly upon
receipt by Buyer or the Company of notice of any pending or Threatened Tax
audits or assessments which may materially affect the Tax liabilities of the
Company or Seller or for which Seller could be required to indemnify Buyer
pursuant to Section 11.3 (a "Tax Claim"). If (i) Buyer's Notice is not given
within 30 days of Buyer's receipt of written notice of the Tax Claim, or (ii)
Buyer's Notice fails to reasonably describe such notice, in each case taking
into account the facts and circumstances with respect to such Tax Claim, the
Seller will not be liable to the Buyer to the extent the Seller's ability to
effectively contest the Tax Claim is prejudiced.

                                       41
<PAGE>

      In the event of a third-party claim for Taxes, Buyer will permit Seller,
at its expense, to control any Proceeding relating to any taxable year or period
of the Company ending on or before the Closing Date. Seller will not settle or
otherwise compromise any issue or matter on a basis that could adversely affect
Buyer's liability for Taxes (including any indemnification for Taxes pursuant to
Section 11.2 or the imposition of tax deficiencies) without Buyer's prior
written consent, which consent will not be unreasonably withheld. If Seller does
not assume the defense of any such Proceeding, Buyer may, without any effect to
its right of indemnification by Seller under this Article 11, defend the same in
such manner as it may deem appropriate. No claim for Taxes relating to a
Pre-closing Period will be settled, either administratively or after
commencement of litigation, on a basis that could adversely affect the Seller's
liability for Taxes (including any indemnification for Taxes pursuant to Section
11.3 or the imposition of tax deficiencies) without Seller's prior written
consent, which consent shall not be unreasonably withheld. Buyer will control
any Proceeding relating to any taxable year or period of the Company ending
after the Closing Date.

11.6 TIMING OF PAYMENT

      Payment of any amounts due under this Article 11 will be made by Seller or
Buyer, as the case may be, within 14 days of the receipt of reasonable evidence
establishing that such a payment is required. If a payment of any amount due
under this Article 11 is not made within 14 days of the receipt of such request,
interest will accrue at the federal "underpayment" rate set forth at Section
6621(a)(2) of the Code beginning the date of the receipt of such request.

11.7 CHARACTERIZATION OF INDEMNITY PAYMENT

      All amounts paid by Buyer or Seller, as the case may be, by reason of
Sections 10.2, 10.3, 11.2 and 11.3 will be treated to the extent permitted under
applicable Legal Requirements as adjustments to the Purchase Price for all Tax
purposes.

11.8 TRANSACTIONAL TAXES

      Notwithstanding any other provision of this Agreement, all transfer,
documentary, recording, notarial, sales, use, registration, stamp and other
similar Taxes or fees imposed by any U.S. federal, state or local taxing
authority in connection with the Contemplated Transactions will be borne by
Seller regardless of which party is obligated to pay such Tax under applicable
Legal Requirements; any such Taxes or fees imposed by any Swiss or other
European national or local taxing authority in connection with the Contemplated
Transactions will be borne by Buyer regardless of which party is obligated to
pay such Tax under applicable Legal Requirements. Buyer and Seller will
cooperate in timely making and filing all Tax Returns as may be required to
comply with Legal Requirements relating to such Taxes.

11.9 TAX SHARING AGREEMENTS

      Seller will cause the Company to terminate as of the Closing Date any Tax
sharing, indemnity or allocation agreement between the Company and any other
party.

11.10 TAX ELECTIONS; NET OPERATING LOSSES

                                       42
<PAGE>

      From and after the date hereof, Seller will not, without the prior written
consent of Buyer (which consent may not be unreasonably withheld), make or
revoke, or cause or permit to be made or revoked, any Tax election with respect
to the Company. Notwithstanding the foregoing, Seller intends to reattribute all
of the Company's net operating losses ("NOLs") to Seller's consolidated group
prior to the Closing Date and Buyer hereby agrees to cooperate with Seller and
the Company in furtherance thereof, including participating fully in a timely
manner in all requirements of Treasury Regulation Sections 1.1502-20(g) and
1.1502-96(b) in order to allow Seller to reattribute the Company's NOLs to
Seller's consolidated group.

11.11 TAX RECORDS

      Seller will make available to Buyer such records as Buyer may require for
the preparation of any Tax Return and such records as Buyer may require for the
defense of any Proceeding concerning such Tax Return. Buyer will make available
to Seller such records as Seller may require for the preparation of any Tax
Return and such records as Seller may require for the defense of any Proceeding
concerning any such Tax Return.

11.12 FOREIGN INVESTMENT IN REAL PROPERTY TAX ACT AFFIDAVIT

      At the Closing, Seller will deliver an affidavit stating, under penalties
of perjury, Seller's U.S. taxpayer identification number and that Seller is not
a "foreign person" as defined in Section 1445 of the Code.

11.13 MISCELLANEOUS

      (a) Except as expressly provided in Article 10, this Article 11 and the
representations and warranties in Section 3.17 are the sole such provisions in
this Agreement governing Tax matters. Except as expressly provided in Article
10, this Article 11 is the sole provision governing indemnification for Tax
matters addressed in Section 3.17 and in this Article 11.

      (b) The covenants and agreements of the parties contained in this Article
11 and the representations and warranties contained in Section 3.17 will survive

Agreement.

                                OTHER AGREEMENTS

12.1 PUT OPTION WITH RESPECT TO RUN-OUT ENGINES

      (a) As of the Closing Date and for a period of three years thereafter (the
"Exercise Period"), Buyer and Company hereby irrevocably grant and issue to
Seller the right and option (the "Put Option") to sell any and all of the
Run-Out Engines to the Company. The Put Option is exercisable by Seller with
respect to each Run-Out Engine at any time after the Put Exercise Date as
contained in Schedule 12.1 by the delivery to the Company and Buyer of a written
notice identifying such Run-Out Engine and the Put Exercise Price. All Run-Out
Engines delivered pursuant to the exercise of the Put Option will be free of all
Encumbrances. Seller shall not be required to exercise the Put Option with
respect to any or all of the Run-Out Engines.

                                       43
<PAGE>

      (b) The exercise price for the Put Option (the "Put Exercise Price") for
each of the Run-Out Engines will be equal to the amount set forth on Schedule
12.1.

      (c) Within 30 days of receipt of the notice delivered pursuant to Section
12.1(a), Buyer will cause the Company to, and the Company will, transfer to
Seller the amount of the Put Exercise Price and Seller will deliver (at its
expense) the Run-Out Engines with respect to which the Put Option is exercised
to the Company's facility in California.

12.2 SALES OF INVENTORY

      (a) Within 24 months following the Closing Date (the "Sales Period"), the
Company shall, in a reasonable commercial manner consistent with past practice,
dispose of the May 31 Inventory owned by the Company on the Closing Date. The
value received for the disposition of such May 31 Inventory after the Closing
Date shall be known as the "Disposition Value".

      (b) For the purposes of this Section 12.2, the following terms will apply:

            (i) "WLFC Revenue Adjustment" will mean the proportion of the
      Disposition Value which Buyer will pay, or will cause the Company to pay,
      to Seller within one month after the expiration of each calendar quarter
      in the Sales Period.

            (ii) The "Lower Threshold" will equal 105% of the Inventory Value.

            (iii) The "Middle Threshold" will equal 118.333% of the Inventory
      Value.

            (iv) The "Upper Threshold" will equal 138.333% of the Inventory
      Value.

      (c) The WLFC Revenue Adjustment will be calculated as follows:

            (i) If the Disposition Value is less than or equal to the Lower
      Threshold, the WLFC Revenue Adjustment will equal zero.

            (ii) If the Disposition Value is greater than the Lower Threshold
      but is less than or equal to the Middle Threshold, the WLFC Revenue
      Adjustment will equal the difference between the Disposition Value and the
      Lower Threshold.

            (iii) If the Disposition Value is greater than the Middle Threshold
      but is less than or equal to the Upper Threshold, the WLFC Revenue
      Adjustment will equal the sum of:

                  (1) the difference between the Middle Threshold and the Lower
            Threshold; and

                  (2) 75% of the difference between the Disposition Value and
            the Middle Threshold.

            (iv) If the Disposition Value is greater than the Upper Threshold,
      the WLFC Revenue Adjustment will equal the sum of:

                                       44
<PAGE>

                  (1) the difference between the Middle Threshold and the Lower
                  Threshold;

                  (2) 75% of the difference between the Upper Threshold and the
                  Middle Threshold; and

                  (3) 50% of the difference between the Disposition Value and
                  the Upper Threshold.

      (d) Buyer will cause the Company to consult with Seller as to the manner
and the terms of any transaction (or series of transactions) that results in a
disposition of the Closing Date Inventory for consideration in excess of
U.S.$1,000,000.

      (e) After the Closing Date and until the 24 month anniversary of the
Closing Date, Buyer will provide Seller with monthly reports of sales of the May
31 Inventory made in the previous month. Upon Seller's request and at Seller's
cost and expense, Buyer will provide Seller with an accounting of all matters
relating to Sections 12.2(a) through (d) and will make all books and records
relating to any of the forgoing matters available to Seller upon reasonable
notice, during normal business hours.

12.3 UCC TERMINATION STATEMENTS AND RELEASES

      As promptly as practicable after the Closing Date and after receipt from
First Union National Bank, Seller will deliver to Buyer a release from First
Union National Bank of the obligations of Company under the Revolving Credit
Agreement and UCC termination statements or amendments to UCC filings, as and if
applicable, relating to the Company's assets covered by the Revolving Credit
Agreement (the "Termination Statements").

12.4 ESTIMATION OF INVENTORY VALUE

      No later than ten days prior to Closing, Seller will deliver to Buyer a
statement based on the Company's unaudited balance sheet at October 31, 2000
reflecting the Adjusted Net Book Value calculated as of October 31, 2000 instead
of as of the Closing Date ("Estimated Adjusted Net Book Value") and the
estimated Closing Date Inventory Value calculated as of October 31, 2000 instead
of as of the Closing Date ("Estimated Closing Date Inventory Value").

12.5 NO USE OF "WILLIS" NAME

      After the Closing, Buyer will use reasonable commercial efforts to cease
using any Marks, Net Names or other Intellectual Property containing "Willis;"
provided that Buyer shall have all right, title and interest in and to the
acronym "WASI."

                                       48
<PAGE>

effect. Any provision of this Agreement held invalid or unenforceable only in

13.12 ENFORCEMENT OF AGREEMENT

      (a) Seller acknowledges and agrees that Buyer could be damaged irreparably
if any of the provisions of this Agreement are not performed in accordance with

adequately compensated in all cases by monetary damages alone. Accordingly,
Seller agrees that, in addition to any other right or remedy to which Buyer may
be entitled, at law or in equity, it will be entitled to enforce any provision

13.13 WAIVER

      The rights and remedies of the parties to this Agreement are cumulative
and not alternative. Neither any failure nor any delay by any party in
exercising any right, power, or privilege under this Agreement or any of the
documents referred to in this Agreement will operate as a waiver of such right,
power, or privilege, and no single or partial exercise of any such right, power,
or privilege will preclude any other or further exercise of such right, power,
or privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement or any of the documents referred to in this Agreement can be

may be given by a party will be applicable except in the specific

                                       49
<PAGE>

instance for which it is given; and (c) no notice to or demand on one party will
be deemed to be a waiver of any obligation of that party or of the right of the
party giving such notice or demand to take further action without notice or
demand as provided in this Agreement or the documents referred to in this
Agreement.

13.14 ARBITRATION SERVICE OF PROCESS

      (a) Any Proceeding arising out of or relating to this Agreement (or breach
thereof) whether arising in tort, contract or otherwise, will be in accordance
with the following procedures:

            (i) The parties, on written notice of a Proceeding given by one

            (ii) If the parties are unable to reach such a solution within a

            (v) If such Proceeding cannot be resolved by mediation within 60

and costs, photocopying and other preparation

                                       50
<PAGE>

expenses. The costs and other fees charged by the independent mediator or AAA,
whether in connection with a mediation and/or arbitration, will be shared
equally by the parties.

other provisions of the Agreement will remain in full force and effect and are
specifically adopted and affirmed by each Party.

_________________, 2000, by and between WILLIS LEASE FINANCE CORPORATION, a
corporation organized under the laws of the State of Delaware ("WLFC"), and
WILLIS AERONAUTICAL SERVICES, INC., a corporation organized under the laws of

                                    RECITALS

      WHEREAS, WASI, which has been divested by WLFC, desires to obtain from
WLFC certain management, administrative and support services, for a limited
period of time, related to the operation of WASI's business.

      WHEREAS, the capitalized terms used herein and not otherwise defined in
the text hereof will have the meanings ascribed to them in the Share Purchase
Agreement dated November 7, 2000 by and among SR Technics Group America, Inc., a
Delaware corporation, and WLFC (the "Share Purchase Agreement").

                                    AGREEMENT

      In consideration of the mutual promises and covenants set forth herein and
intending to be legally bound, the parties agree as follows:

1. Extent of Services

      1.1 WLFC will provide to WASI the administrative, support and other
services (each, a "Transition Service," and collectively, the "Transition
Services") set forth on Schedule A.

      1.2 WLFC will make a specific employee of WLFC available to WASI to
provide certain executive management services (the "Executive Services"). The
name of this specific employee and the description of the services to be
performed are set forth on Schedule B. The terms under which this individual
will perform the Executive Services are more specifically defined in that
certain Consulting Agreement dated as of the date hereof by and among Donald A.

      1.3 The Transition Services and the Executive Services will be known,
collectively, as the "Services".

2. Term

      2.1 This Agreement shall be effective as of the Closing Date.
<PAGE>

      2.2 The Executive Services will be provided for a period of three months
from the Closing Date.

      2.3 The Transition Services will be provided for an initial term of three
months and may be renewed from month to month thereafter upon the mutual written
consent of the parties with the aim of WLFC assisting in the transition of WASI
to a stand-alone entity.

      2.4 WASI will coordinate with WLFC as to the exact scope of Services that
will be requested from time to time.

3. Quality

      3.1 In providing the Transition Services, WLFC will employ the same
standard of care that it employs in providing the services in Schedule A to WLFC
or any of its affiliates.

      3.2 In providing the Executive Services, WLFC will ensure that the
individual named in Schedule B will perform the services detailed therein with
the same standard of care that would be expected of him if he were providing
those services to WLFC or any of its affiliates.

4. Charges For Services; Payment.

      4.1 Payment of Fee.

            In consideration for WLFC providing the Services to WASI, WASI
agrees to pay a fee to WLFC (the "Fee") which will be calculated in accordance
with the terms of Section 4.2.

      4.2 Calculation of Fee.

            The Fee will be calculated monthly in accordance with the following
provisions:

            (a) WLFC will determine the total direct costs and expenses
            (excluding overhead and other indirect costs and expenses) incurred
            in each month (or part thereof) to provide the Services under this
            Agreement (the "Costs"). The Costs will consist of the following:

                  (i) all direct costs and expenses incurred by WLFC in
                  performance of the Services; and

                  (ii) an appropriate proportionate allocation of any direct
                  costs and expenses incurred by WLFC partly in performance of
                  the Services and partly in relation to other matters.

            (b) The Fee will be equal to the aggregate of the Costs plus 12.5%.

      4.3 Payment.

            After the end of each month of the term (including any month
occurring after the extension of the initial term) of this Agreement, WLFC will
provide an invoice to WASI, detailing the services provided and providing
support for the calculation of the Fee. WASI will

pay the Fee (plus any applicable sales and service taxes) within 30 days after
invoicing by WLFC, by check or wire transfer to a bank account designated by
WLFC.

5. Liability; Indemnity.

      5.1 Indemnity.

            WASI will indemnify, defend and hold WLFC, its Affiliates and each
of their respective directors, officers, employees and agents harmless from and
against any loss, liability, claim, damage or expense (including reasonable
legal fees and expenses) suffered or incurred by any such indemnified party to
the extent relating to or arising from (i) the acts or omissions of WASI, its
Affiliates, employees, agents or contractors in connection with the performance
of the Services; (ii) any breach by WASI of any of its obligations under this
Agreement; or (iii) the performance of Services hereunder by WLFC; provided,
however, that WASI will have no such indemnification obligations (x) if WLFC has
not complied with its performance standard as set forth in Section 3 and such
failure to comply is the cause of such loss, liability, claim, damage or expense
or (y) to the extent relating to or arising from the gross negligence or willful
misconduct of WLFC and/or its Affiliates, directors, officers, employees and
agents.

      5.2 Duty to Mitigate.

            Each party will have the duty to mitigate damages for which the
other party may become responsible.

6. Miscellaneous

      6.1 No Assignment; No Third Party Beneficiaries.

            Neither party may without prior written consent of the other party
assign or delegate any of its rights or obligations under this Agreement, such
consent not to be unreasonably withheld. This Agreement will be for the benefit
of the parties only, and there are no intended third party beneficiaries.

      6.2 Notices.

      6.4 Confidentiality.

of its Affiliates, officers, directors, employees and agents to, hold all
non-public information relating to the business of the other party disclosed to
such person by reason of this Agreement confidential and will not disclose any
such information to any Person unless legally compelled to do so; provided,
however, that to the extent that any party may become so legally compelled, it
may only disclose such information if it will first have used reasonable efforts
to, and, if practicable, will have afforded the other party the opportunity to
obtain, an appropriate protective order or other satisfactory assurance of
confidential treatment for the information required to be so disclosed.

      6.5 Relationship Of Parties.

            Except as provided in this Agreement, the Share Purchase Agreement
or any Ancillary Agreement, none of the parties will act or represent or hold
out as having authority to act as an agent or partner of any other party, or in
any way bind or commit the other party to any obligations and nothing contained
in this Agreement will be construed as creating a partnership, joint venture,
agency, trust or other association of any kind, each party being individually
responsible only for its obligations as set forth in this Agreement. WASI
acknowledges and agrees that the Executive listed on Schedule B is an executive
officer and director of WLFC, and as such owes his primary duty of loyalty
(including a fiduciary duty) to WLFC.

            This Agreement may be executed in one or more counterparts, each of
which will be deemed to be an original copy of this Agreement and all of which,
