                       FIRST AMENDMENT TO RIGHTS AGREEMENT

      THIS FIRST AMENDMENT TO RIGHTS AGREEMENT (this "Amendment"), is entered
into by and between WILLIS LEASE FINANCE CORPORATION, a Delaware Corporation
(the "Company") and AMERICAN STOCK TRANSFER & TRUST COMPANY, a trust company
organized under the laws of the State of New York, as rights agent (the "Rights
Agent"), and shall be deemed effective as of __________, 2000 (the "Effective
Date").

                                    RECITALS

      WHEREAS, the Company and the Rights Agent entered into a Rights Agreement
dated September 24, 1999 (the "Rights Agreement") to provide for the
distribution of preferred share purchase rights for each share of Company common
stock outstanding at the Close of Business (as such term is defined in the
Rights Agreement) on October 12, 1999, which rights represent the right to
purchase one one-hundredth of a preferred share of the Company subject to the
terms and conditions set forth in the Rights Agreement;

      WHEREAS, the Company, FlightTechnics LLC, a Delaware limited liability
company (the "Investor") and certain affiliates of the Investor have entered
into an Investment Agreement dated as of November 7, 2000(the "Investment
Agreement") whereby the Company has (i) agreed to issue and sell and the
Investor has agreed to purchase 1,300,000 shares of the Company's common stock
and (ii) subject to the satisfaction of certain conditions set forth in the
Investment Agreement, the Investor has been given the option to purchase between
1,700,000 shares of the Company's common stock and that number of shares that
when added to the 1,300,000 shares already purchased by the Investor, would
equal 34.9% of the total outstanding common stock of the Company;

      WHEREAS, the Company's Board of Directors (the "Board") has determined
that it is fair and in the best interests of the shareholders of the Company to
amend the Rights Agreement to allow the Investor to purchase shares of the
Company's common stock pursuant to the Investment Agreement without triggering
the preferred share purchase rights under the Rights Agreement; and

      WHEREAS, the Board has voted in favor of this Amendment.

                                    AGREEMENT

      NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
promises, covenants and conditions hereinafter set forth, the parties hereto

                       MEMBER INTEREST PURCHASE AGREEMENT

      This Member Interest 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, 50% of the
outstanding membership interests (the "Interests") of Pacific Gas Turbine
Center, LLC, a Delaware limited liability company (the "Company"), on the terms
set forth in this Agreement.

                                    AGREEMENT

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

                                  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, capitalized terms and variations on
them have the meanings specified in Schedule 1.2.
<PAGE>

                                   ARTICLE 2

      SALE AND TRANSFER OF INTERESTS; CLOSING

2.1 INTERESTS

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

2.2 PURCHASE PRICE

      The purchase price for the Interests (the "Purchase Price") will be U.S.$
15,000,000 (the "Initial Purchase Price"), increased or reduced by the
Adjustment Amount, as appropriate.

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) instruments or other evidence sufficient to transfer to Buyer
title to the Interests; and

            (ii) 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 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 (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 and Principal and Interest Payment 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
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; 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

                                      -2-
<PAGE>

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.

2.5 ADJUSTMENT PROCEDURE

      (a) "Net Book Value" as of a given date means the amount calculated by
subtracting the liabilities from the value of the Company's assets as of that
date. The Net Book Value as of May 31, 2000 is equal to U.S.$18,145,000 the
"Initial Net Book Value").

      (b) Buyer will cause the Company to prepare and will cause
PricewaterhouseCoopers, certified public accountants, to audit a balance sheet
(the "Closing Balance Sheet") of the Company as of the Closing Date. Buyer will
prepare the Closing Balance Sheet in accordance with GAAP applied on a basis
consistent with the accounting policies and procedures used in the preparation
of the Interim Unaudited Company Balance Sheet using period ending or interim
period procedures. Buyer will then determine the Net Book Value as of the
Closing Date (the "Closing Net Book Value") using the same methodology as was
used to calculate the Initial Net Book Value. Buyer will deliver the Closing
Balance Sheet and its Closing Net Book Value to Seller within 60 days after the
Closing Date. If within 30 days following delivery of the Closing Balance Sheet
and the Closing Net Book Value calculation, Seller does not deliver to Buyer
notice of any objection to the Closing Balance Sheet (which notice must contain
a reasonably detailed statement of the basis of Seller's objection), then the
Closing Book Value will be used in calculating the Adjustment Amount in Section
2.5(e).

      (c) If Seller disputes any items of the Closing Balance Sheet, then Seller
will deliver to Buyer, within 30 days following Seller's receipt of the Closing
Balance Sheet, 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
Closing Balance Sheet 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 after 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 Closing Balance Sheet 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

                                      -3-
<PAGE>

so long as a party complies in all material respects in good faith with the
procedures of this Section 2.5, such fees will not include the other party's
outside counsel or accounting fees.

      (e) The Neutral Auditors will recalculate the Closing Net Book Value based
on the resolution of the issues in dispute, and such recalculated Closing Net
Book Value will be used in calculating the Adjustment Amount. The "Adjustment

Account Receivable relating to the amount or validity of such Account
Receivable.

such fact or condition require any change in any Part, Buyer will promptly
deliver to Seller a supplement to the Part specifying such change. During the

9.1 TERMINATION EVENTS

      This Agreement may, by notice given before or immediately prior to the

      (a) by either Buyer or Seller if a material breach of any provision of
this Agreement has been committed by the other party and such breach has not
been waived in writing by the other party;

      (b) by Buyer, if any condition in Article 7 has not been satisfied as of
the Closing Date or if satisfaction of such a condition by such date is or

obligations under this Agreement) and Buyer has not waived in writing such

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

representations in Sections 3.25 and 4.5 and the obligations in Sections 12.1,
12.3 and 12.14 will survive; provided, however, that if this Agreement is
terminated by a party because of the breach of the other party's covenant
obligations under this Agreement or because one or more of the conditions to the
terminating party's obligations under this Agreement is not satisfied as a
result of the other party's failure to comply with its covenant obligations
under this Agreement, the terminating party's right to pursue all legal remedies
will survive such termination unimpaired; provided, further, that 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

                                      -28-
<PAGE>

warranty made by the other party is untrue will be to elect to terminate this
Agreement pursuant to Section 9.1.

                            INDEMNIFICATION; REMEDIES

10.1 SURVIVAL, RIGHT TO INDEMNIFICATION; WAIVER

      All representations, warranties, covenants, and obligations in this
Agreement, the Disclosure Schedule and other Schedules, the supplements to the
Disclosure Schedule and other Schedules, the certificate delivered pursuant to
Section 2.4(a)(ii), and any other certificate or document delivered pursuant to
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.

10.2 INDEMNIFICATION BY SELLER

      Subject to Sections 10.4 and 10.5, Seller will indemnify and hold harmless
Buyer and its Representatives, equity owners, controlling persons and
affiliates, other than the Company (collectively, the "Buyer Indemnitees") for,
and will pay to the Buyer Indemnitees the Adjusted 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 Seller in this
Agreement as of the date of this Agreement giving effect to the Disclosure
Schedule and any supplements to the Disclosure Schedule;

      (b) any breach of any representation or warranty made by Seller in this
Agreement as of the Closing Date giving effect to the Disclosure Schedule and
any supplements to the Disclosure Schedule;

      (c) any breach of any representation or warranty made by Seller in any
certificate or document delivered by Seller pursuant to this Agreement;

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

                                      -29-
<PAGE>

      (e) any aggregate Liabilities of the Company existing at or arising out of
a state of facts existing at or before the Closing Date, to the extent that such
Liabilities are not reflected or reserved against in the Interim Unaudited
Company Balance Sheet;

      (f) any matter disclosed in Part 3.21;

      (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;
and

      (h) any and all Proceedings, demands or assessments incidental to any of
the matters set forth in Section 10.2(a) through (g).

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) unless a release shall be obtained from the lessor thereunder, 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) 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 such Person with Buyer (or any Person acting on its behalf) in
connection with any of the Contemplated Transactions;

      (d) unless a release shall be obtained from the lessor thereunder, any
Liabilities arising under the Company Lease subsequent to Closing and 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 (c).

Notwithstanding the foregoing, indemnification for breach of a covenant or
obligation contained in Article 11 will be governed by Article 11 (except as
expressly set forth in this Article 10).

indemnification or otherwise) under Section 10.2 or Article 11 unless and until
the monetary value of the Adverse Consequences suffered by the Buyer

Buyer Indemnitees shall 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

      (c) Notwithstanding any other provision in this Agreement, and in addition

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
10 and Article 11 with respect to any Liability or Adverse Consequences suffered

<PAGE>

U.S.$200,000, and (ii) Buyer's maximum liability to the Seller Indemnitees in
respect of Buyer's indemnification obligations under Section 10.3, in the

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
written 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 written 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.

      (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.

                                      -32-
<PAGE>

      (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).

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 written notice to the party obligated to indemnify and
will be paid promptly after such notice.

                                   ARTICLE 11

                                   TAX MATTERS

11.1 TAX RETURNS

      The Company, in consultation with 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, using accounting methods and
other practices that are consistent with those used by the Company in its prior
Tax Returns. Tax Returns for the short period ending on the Closing Date will be
prepared by taking into account Treasury Regulation Section 1.706-1(c)(1) or any
similar provision of state, local or foreign law, which requires a complete
closing of the partnership books on the Closing Date.

11.2 INDEMNIFICATION OF SELLER

      Buyer will indemnify and hold harmless Seller Indemnitees 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 Buyer Indemnitees for Taxes arising out of
or relating to: (a) the Company for the Pre-Closing Period and (b) 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.

                                      -33-
<PAGE>

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 1.706-1(c)(1) (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 based on a closing of the books of the Company; provided that
(i) exemptions, allowances or deductions that are calculated on a 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 written 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.

      In the event of a third-party claim for Taxes, Seller will be entitled to
participate, at its expense, in 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 elect to participate in the defense of any such Proceeding,
the Company may, without any effect on Buyer's right of indemnification by
Seller under this Article 11, defend the same in such manner as it may deem
appropriate, provided that 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 Seller's liability for Taxes (including any
indemnification for Taxes pursuant to Section 11.3 or the imposition of tax
deficiencies) without the prior written consent of Seller, which consent shall
not be unreasonably withheld. The Company 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 30 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 30 days of the receipt of such request,
interest will accrue at the federal

                                      -34-
<PAGE>

"underpayment" rate set forth in Section 6621(a)(2) of the Code beginning on the
31st day after 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 obliged 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

      (a) Seller will not unreasonably withhold its consent (if such consent is
required) to the making of a Section 754 election with respect to the Company,
effective for the taxable period ending on the Closing Date

      (b) Within 90 days after the Closing Date, Buyer will prepare an
allocation required under Section 755 of the Code.

11.11 TAX RECORDS

      The Company 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 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
representation and warranties contained in Section 3.17 are the sole provisions

12.12 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
the specific terms and that any breach of this Agreement by Seller could not be

be entitled, at law or in equity, it will be entitled to enforce any provision
of this Agreement by a decree of specific performance and to temporary,
preliminary and permanent injunctive relief to prevent breaches or threatened

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

claim or right unless in writing signed by the other party; (b) no waiver that
may be given by a party will be applicable except in the specific instance for
which it is given; and (c) no notice to or demand on one party will be deemed to
