                           (B)      if the Net Maintenance Amount as of the
                                    relevant Closing Date is a positive number
                                    (i.e., the Maintenance Reimbursement Amount
                                    exceeds the Required Maintenance Expenses),
                                    then AerFi shall pay to AerCo the Net
                                    Maintenance Amount and if the Net
                                    Maintenance Amount as of such Closing Date
                                    is a negative number (i.e., the Maintenance
                                    Reimbursement Amount is less than the
                                    Required Maintenance Expenses), then AerCo
                                    shall pay to AerFi the Net Maintenance
                                    Amount.

         (b)      Any amounts described in Clause 2.2(a)(v) shall be paid on the
                  Reimbursement Date immediately succeeding the relevant Closing
                  Date. All other amounts payable under this Clause 2.2 shall be
                  made on the relevant Closing Date.

         (c)      For the purposes of Exhibit A, the delivery position of each
                  Aircraft shall be determined sequentially according to the
                  date on which the Shares in the relevant Company are
                  transferred and if thereby more than one Aircraft is delivered
                  on a particular Closing Date, AerCo shall determine the
                  delivery position of each Aircraft in its sole discretion.

         (d)      An amount equal to the Security Deposits with respect to the
                  Aircraft owned by the Companies whose Shares are transferred
                  on each Closing Date shall be transferred from the Aircraft
                  Purchase Account to the Collection Account to be held as part
                  of the Liquidity Reserve Amount.

         (e)      On the Offering Closing Date AerCo shall issue D Notes in an
                  initial principal amount of $80,000,000 to refinance the Sub
                  class D-1 Notes.

         benefit of any person who is resident in Jersey for the purposes of the
         Income Tax (Jersey) Law 1961 as amended.

         and the Class E Notes for its own account, for investment purposes and

                                       18
<PAGE>   19

         The Sellers acknowledge and agree with the Purchasers that the
         Purchasers have relied on the Sellers' representations and agreements
         set forth in Clause 8 and AerFi's undertaking in Clause 5 that it will
         use its reasonable commercial efforts to meet all conditions precedent
         to the transfer of the Remaining Companies with the Remaining Aircraft
         prior to 10 July 2001 and that AerCo has obtained financing for the
         purpose of purchasing all of the Remaining Companies with the Remaining
         Aircraft. The parties agree that, in order to put AerCo in the economic
         position that it would be in if the Remaining Companies with the
         Remaining Aircraft were all transferred to the Purchasers on the
         Offering Closing Date, and in consideration for such reliance, for each
         Remaining Aircraft, (a) on each Calculation Date occurring prior to the
         Closing Date of the sale of the Shares of the Remaining Company owning
         such Remaining Aircraft or the Non-Delivery Date with respect to such
         Remaining Aircraft or Remaining Company, AerFi shall pay to AerCo an
         amount equal to the Rent Payment for the Rent Transfer Period ending on
         such Calculation Date, and (b) on the Payment Date next succeeding the
         Calculation Date (a "REIMBURSEMENT DATE"), AerCo shall pay to AerFi the
         Rent Payment Reimbursement Amount. On the Calculation Date next
         following the Closing Date of the sale of the Shares in the Company
         owning a Remaining Aircraft or a Non-Delivery Date with respect to a
         Remaining Aircraft, AerFi shall pay to AerCo all Rent Payments relating
         to such Remaining Aircraft received for the period from and including
         the immediately preceding Calculation Date (or if none, the Offering
         Closing Date) to but excluding such Closing Date or Non-Delivery Date,
         as the case may be (the "END PERIOD") and, on the following
         Reimbursement Date, AerCo shall pay to AerFi interest received on all
         funds in the Aircraft Purchase Account during such End Period referable
         to the Aircraft and an amount equal to the interest, if any, on the D
         and E Notes which would actually have been payable on the Payment Date
         next succeeding such Calculation Date had the principal amount of the D
         and E Notes allocable to such Remaining Aircraft been outstanding
         during such End Period. If at any time following the Closing Date or
         Non-Delivery Date with respect to a Remaining Company or Remaining
         Aircraft, the Sellers receive any Rent Payment in respect of any period
         ending on such Closing Date or Non-Delivery Date or, if any at time
         following the Closing Date with respect to a Remaining Company or
         Remaining Aircraft, the Seller(s) shall receive any Maintenance Rent in
         respect of such Remaining Company or Remaining Aircraft, AerFi shall,
         promptly upon receipt thereof, pay such amount to AerCo.

         Except as otherwise provided in this Clause 4, neither AerFi nor AerCo
         shall have any obligation to make any payments with respect to a
         Remaining Aircraft pursuant to this Clause 4 to the extent such
         payments relate to any period following the earlier of the Closing Date
         of the sale of the Shares in the Company owning such Remaining Aircraft
         and the Non-Delivery Date for such Remaining Aircraft or Remaining
         Company.

5.       ADDITIONAL AerFi OBLIGATIONS WITH RESPECT TO REMAINING AIRCRAFT

         AerFi shall be fully responsible for payment of all Lease Expenses and
         Required Maintenance Expenses with respect to each Remaining Aircraft
         during the period from the Offering Closing Date until the earlier of
         (a) a Non-Delivery Date with respect to that Remaining Aircraft and (b)
         the Closing Date of the sale of the

                                       19
<PAGE>   20

         Shares in the Company owning that Remaining Aircraft. AerFi represents
         and covenants with AerCo that it shall use its reasonable commercial
         efforts to ensure that all Aircraft not owned by Companies the Shares
         in which are transferred to the Purchasers on the Offering Closing Date
         are transferred to the Purchasers prior to 10 July 2001. AerFi
         acknowledges that such efforts may involve the payment of money by
         AerFi to release certain liens on such Aircraft and the obtaining of
         certain consents. AerFi agrees to keep AerCo informed of its progress
         in meeting the conditions to the transfer of each such Aircraft and to
         notify AerCo immediately if AerFi reasonably believes that it will have
         to deliver a Termination Notice with respect to any Remaining Aircraft
         or Remaining Company or proposes delivery of a Substitute Aircraft. In
         addition, prior to the Closing Date or, as the case may be,
         Non-Delivery Date occurring, AerFi agrees to provide AerCo on each
         Calculation Date with a written report of the following information
         with respect to each Remaining Aircraft: gross lease receipts received
         from each Lessee of a Remaining Aircraft with a breakdown between
         rental payment and Maintenance Reimbursement Amount, security deposits
         and the form in which they are held, maintenance claims and payments
         and status thereof, Required Maintenance Expenses, Lease Expenses,
         amounts overdue from each Lessee of a Remaining Aircraft (with
         explanation of why amounts are overdue and description of
         communications with such Lessee) and any other material information
         relating to each Remaining Aircraft.

6.       SUBSTITUTION AND TERMINATION

6.1      SUBSTITUTION: AerCo may in its sole discretion agree to accept a
         Substitute Aircraft proposed by AerFi provided that (a) such Substitute
         Aircraft (i) is no more than seven years old as of 17 July, 2000, (ii)
         is subject to an operating lease contract, or letter of intent for an
         operating lease contract, that is to become effective within 90 days
         after the signing of such letter of intent, (iii) is of the same type
         as the undelivered Aircraft and (iv) does not give rise to a
         Concentration Default and (b) AerCo shall have received a Rating Agency
         Confirmation (as defined in the Notes Indenture) with respect to such
         substitution. AerFi shall have obtained an appraisal of the Base Value
         of such Substitute Aircraft from the Appraisers as of the date which is
         no more than 30 days prior to the Closing Date with respect to the
         relevant Remaining Company.

6.2      TERMINATION: If AerFi determines with respect to any Remaining Aircraft
         or Remaining Company that, using its reasonable commercial efforts, it
         will not be able to meet the conditions set forth in Clause 13 hereto
         with respect to the transfer of such Remaining Aircraft or Remaining
         Company and will not be able to provide a Substitute Aircraft
         acceptable to AerCo, AerFi shall give written notice to AerCo to that
         effect (each such notice a "TERMINATION NOTICE"), specifying the
         Remaining Aircraft or Remaining Company to which such Termination
         Notice applies and the reasons for its inability to meet such
         conditions. Upon the delivery of such Termination Notice, the
         obligations of the relevant Seller(s) to transfer such Remaining
         Aircraft or to sell the Shares of that Remaining Company to the
         relevant Purchaser shall terminate and no party shall have any
         liability to any other party, whether under this Agreement, the Deed of
         Tax Indemnity or any other Transaction Document, in relation to such
         Remaining Aircraft or Remaining Company, subject to payment of amounts

         (b)      with respect to all Remaining Aircraft at such time, upon the
                  earliest to occur of:

                  (ii)     AerFi becoming or being declared insolvent, or an
                           examiner or receiver or liquidator or similar officer
                           being appointed over AerFi or over all or a
                           substantial part of its assets, or AerFi making an
                           arrangement for the benefit of its creditors
                           generally or AerFi taking steps (or steps being taken

                  (iii)    an event or condition which results in the

         to indemnify the Sellers and their Affiliates, and any of their
         successors and assigns, officers, directors, servants, agents and
         employees (each a "PURCHASER INDEMNITEE") from and against any claims,
         damages, losses, costs, expenses, fees (including counsel's fees),
         payments, demands, liabilities, actions, proceedings, penalties or
         fines (together, the "LOSSES") which any Purchaser Indemnitee may incur
         or suffer, (i) in relation to any Aircraft to the extent it arises out
         of a loss or liability relating to acts or omissions (other than acts
         or omissions of a Purchaser Indemnitee) after the Closing Date of the
         sale of the Shares in the Company owning such Aircraft, or (ii) in
         relation to any misrepresentation or breach of warranty, covenant or
         agreement made or to be performed by the Purchasers pursuant to this
         Agreement (together the "PURCHASER Indemnity"), provided that:-

         (a)      such loss or liability would exceed in the aggregate US$4
                  million and, in such event, subject to Clause 10 hereof, the
                  Purchaser agrees to indemnify for the full amount of such loss
                  or liability; and

         (b)      the Purchaser Indemnity shall not extend to any claim on
                  account of any Taxes occasioned by any delivery of Aircraft.


9.2      SELLER INDEMNITY: The Sellers hereby jointly and severally agree to
         indemnify the Purchasers and their Affiliates, and any of their
         successors and assigns, officers, directors, servants, agents and
         employees (each a "SELLER INDEMNITEE" and, together with the Purchaser
         Indemnitees, the "INDEMNIFIED PARTIES") against any Losses arising out
         of or resulting from:-

         (a)      the breach by the Sellers of any Warranty;

         (b)      the breach of any covenant or agreement contained in this
                  Agreement by the Sellers; and

         (c)      non-agreed Liabilities of any Company not reflected on the
                  Reference Balance Sheet of that Company, whether arising
                  before or after the Closing Date of the sale of the Shares in
                  that Company, that are directly caused by any action or
                  inaction on the part of the Company prior to such Closing Date
                  other than any actions or inactions in the ordinary course of
                  the business of the relevant Company,

         in each case whether or not any action, investigation, litigation or
         proceeding relating thereto is brought by the Purchasers, the Sellers
         or any other Seller Indemnitee and whether or not a Seller Indemnitee
         is otherwise a party thereto. To the extent that the Sellers'
         undertakings in this Clause 9.2 may be unenforceable,

                                       23
<PAGE>   24

         the Sellers shall jointly and severally contribute the maximum amount
         that they are permitted to contribute under any applicable law to the
         payment and satisfaction of all Losses incurred by the Purchasers or
         any Company which any Seller Indemnitee may incur or suffer, provided
         that the indemnity contained in this Clause 9.2 shall not extend to or
         cover any liabilities or claims for Losses resulting from, incurred in
         connection with or arising from a Tax liability (it being the intention
         of the parties that claims in respect of Tax would be the subject
         matter of the Deed of Tax Indemnity).

9.3      NOTICE OF CLAIMS:

         (a)      An Indemnified Party shall give the Purchasers or the Sellers
                  (as the case may be) (the "INDEMNIFYING PARTY") notice of any
                  matter which such Indemnified Party has determined has given,
                  or could give, rise to a right of indemnification under this
                  Agreement, within sixty (60) days of such determination. The
                  notice shall state the amount of the Loss, if known, and the
                  method of its calculation and shall contain a reference to the
                  provisions of this Agreement in respect of which such right of
                  indemnification is claimed or arises.

         (b)      If an Indemnified Party receives written notice of any third
                  party claim or potential claim ("THIRD PARTY Claim") against
                  it which is or may be the subject of a claim by it under the
                  Purchaser Indemnity or the Seller Indemnity (as the case may
                  be), the obligations and liabilities of the Indemnifying Party
                  under this Clause 9 shall be subject to the following terms
                  and conditions:-

                  (i)      the Indemnified Party shall give written notice
                           thereof to the Indemnifying Party within thirty (30)
                           days of receipt of such notice provided that failure
                           to give such notice shall not release the
                           Indemnifying Party from any of its obligations under
                           this Clause 9 except to the extent such Indemnifying
                           Party has been released from any other obligation or
                           liability that it may have to an Indemnified Party
                           otherwise than under this Clause 9;

                  (ii)     the Indemnifying Party shall be entitled to assume
                           and control the defence of such Third Party Claim and
                           take such further action to contest, resist or appeal
                           the validity, applicability and amount of such claim
                           in appropriate administrative or judicial proceedings
                           either:-

                           (A)      in the name of the Indemnified Party
                                    (provided the Indemnifying Party shall
                                    indemnify and secure the Indemnified Party
                                    to its reasonable satisfaction against all
                                    losses costs damages and expenses which may
                                    be incurred thereby), or

                           (B)      in its own name,

                  in either case, at its own expense and through retaining legal
                  advisers of its choice provided that it gives notice of its
                  intention to do so to the Indemnified Party within five (5)
                  days of receipt of the notice of such Third

                                       24
<PAGE>   25

                  Party Claim from the Indemnified Party; provided however, that
                  if there exists or is reasonably likely to exist a conflict of
                  interest that would make it inappropriate in the judgement of
                  the Indemnified Party, in its sole and absolute discretion,
                  for the same legal advisers to represent both the Indemnified
                  Party and the Indemnifying Party, then the Indemnified Party
                  shall be entitled to retain its own legal advisers, in each
                  jurisdiction for which the Indemnified Party reasonably
                  determines counsel is required, at the expense of the
                  Indemnifying Party. In the event that the Indemnifying Party
                  exercises its right hereunder to undertake the defence of any
                  such Third Party Claim, the Indemnified Party shall co-operate
                  with the Indemnifying Party in such defence as is reasonably
                  required by the Indemnifying Party. In the event that the
                  Indemnified Party is, directly or indirectly, conducting the
                  defence against any such Third Party Claim, the Indemnifying
                  Party shall co-operate with the Indemnified Party in such
                  defence as is reasonably required by the Indemnified Party. No
                  such Third Party Claim may be settled by the Indemnifying
                  Party without the prior written consent of the Indemnified
                  Party and no such Third Party Claims may be settled by the
                  Indemnified Party without the prior written consent of the
                  Indemnifying Party.

9.4      TO BE MADE FREE FROM DEDUCTIONS: All sums payable under or pursuant to
         the Purchaser Indemnity or the Seller Indemnity shall be paid free and
         clear of all deductions or withholdings whatsoever save only as may be
         required by law. If any such deductions or withholdings are required by
         law the Indemnifying Party shall be obliged to pay to the Indemnified
         Party such sums as will after such deduction or withholding have been
         made leave the Indemnified Party with the same amount as it would have
         been entitled to receive in the absence of any such requirement to make
         a deduction or withholding together with interest on the amount payable
         by the Indemnifying Party under this sub-clause at a rate equal to the
         rate of interest applicable to the AerCo Group Class D Notes (as
         defined in the Notes Indenture) in respect of the period commencing on
         the date upon which payment of the full amount was due until payment by
         the Indemnifying Party of such amount is made (both before and after
         judgement). If any sum payable by the Indemnifying Party under or
         pursuant to the Purchaser Indemnity or the Seller Indemnity is subject
         to tax in the hands of the Indemnified Party the same obligation to
         make an increased payment shall apply in relation to such tax liability
         as if it were a deduction or withholding required by law. For the
         avoidance of doubt, the parties hereby agree and confirm that any
         Indemnifying Party shall not be under any obligation to make any
         payment to any Indemnified Party under this Clause 9.4 to the extent
         that the Indemnified Party would be in a better position than if no
         payment by way of indemnity was required to be made.

10.      LIMITATIONS ON WARRANTIES AND INDEMNITIES

10.1     TIME LIMIT ON CLAIMS: No claim arising out of the sale of the Shares in
         any Company shall be brought by the Purchasers in respect of any breach

         Each of the Sellers hereby agrees that, with respect to any claim under
         a Purchaser Indemnity, the Seller shall be entitled to payment only to
         the extent that all amounts payable in items "First" through
         "Twenty-Seventh" in Section 3.08(a) of the Notes Indenture have been
         paid in full.

10.3     EXCLUSION OF SMALL CLAIMS: The Sellers shall only be liable in respect
         of any claim brought by the Purchaser for a breach of the Warranties or
         Seller Indemnity if the aggregate liability of the Sellers for such
         claims, when aggregated with any claims under the Deed of Tax
         Indemnity, would exceed in aggregate US$4.25 million (the "THRESHOLD").
         In the event that such claim or claims exceed the Threshold, the
         Sellers shall be liable (subject to Clause 10.2(a)) for the full amount
         of such claim.

10.4     RETROSPECTIVE LEGISLATION: The Sellers shall not be liable for any

         statutory instrument passed or the occurrence of any analogous event
         after the date of this Agreement.

         is a party to this Agreement in its capacity only as holder of shares
         in the Irish Companies as nominee for AerFi. Skyscape's maximum
         liability to the Purchasers in respect of any claims under this
         Agreement (including any breaches of Warranty or under the Seller
         Indemnity) or under the Deed of Tax Indemnity shall be limited to
         IR(pound)1.

12.      ADDITIONAL COVENANTS AND AGREEMENTS

12.1     FURTHER ACTION: At the request of the Purchasers, the Sellers and each
         of them shall (and shall procure that any other necessary parties
         shall) execute and do all such documents, acts and things as may
         reasonably be required by any Purchaser subsequent to the date hereof
         and to any Closing of the sale of Shares to that Purchaser in order to
         perfect the right, title and interest of the relevant Purchaser to and
         in any Shares which have been purchased by it and to procure the
         registration of the relevant Purchaser and/or its nominee(s) as the
         registered holder(s) of the relevant Shares. The Sellers shall deliver
         supplements to the Disclosure Letter as and when necessary to ensure
         that information therein relating to the Remaining Aircraft is accurate
         and current.

12.2     INSURANCE: Each Purchaser covenants and agrees to use its best
         endeavours to procure or to cause the Lessees of all Aircraft owned by
         any Company acquired by either Purchaser pursuant to this Agreement to
         continue to maintain in accordance with the terms of the Leases until
         the third anniversary of the Closing Date of the sale of the Shares in
         that Company, insurances relating to the Aircraft naming as additional
         insureds those of the Sellers or their Affiliates, or any existing
         Servicer of any of them, who are named as insureds on the insurance
         policies in effect at the applicable Closing Date. In the event that
         any such existing insurance coverage in respect of the Sellers or their
         Affiliates, or any existing Servicer, cannot be maintained, the
         Purchasers shall provide written notice to the Sellers before such
         coverage is terminated.

12.3     MANUFACTURERS' WARRANTIES/ FURTHER ASSURANCE: The Sellers agree to
         assign, or, as appropriate, to use their best endeavours to procure
         that their Affiliates assign to the relevant Company, to the extent
         permitted by law, any rights and benefits under any manufacturers'
         warranties still in effect to the extent that they (a) relate to the
         Aircraft owned or acquired by that Company and (b) have not already
         been assigned to the relevant Company. After the date of this Agreement
         and each applicable Closing Date, the Purchasers and the Sellers

                                       27
<PAGE>   28

         agree to take all appropriate action which may be reasonably necessary
         or advisable to carry out any of the provisions hereof; provided that,
         with respect to carrying out the assignments referred to in the
         preceding sentence, the Sellers shall not be obliged to seek the
         consent of any such manufacturer.

                  and adversely alter the transactions contemplated hereby which
                  the Purchasers reasonably believe is likely to render it
                  impossible or unlawful for any of the parties to perform their
                  obligations hereunder or which could have a Material Adverse
                  Effect and the Purchasers having received a duly executed

         Purchasers under this Agreement are further conditional upon no change

         their respective obligations under this Agreement or such Other
         Transaction Documents or Related Documents; provided, however, that if

         restructure their respective obligations under this Agreement so as to
         avoid the aforementioned illegality.

14.      MISCELLANEOUS

14.1     WAIVER: The Sellers or the Purchasers may extend the time for the

         thereby. The Sellers may waive any inaccuracies in the representations
         and warranties of the Purchasers or any condition to the Closing of the

         the Trustee under the Notes Indenture and after having obtained a
         Rating Agency Confirmation (as defined in the Notes Indenture). Any
         waiver of any term or condition shall not be construed as a waiver of
         any subsequent breach or a subsequent waiver of the same term or
         condition, or a waiver of any other term or condition, of this
         Agreement. The failure by any party to assert any of its rights
         hereunder shall not constitute a waiver of any of such rights.

14.2     EXPENSES: Except as otherwise specified in this Agreement, each party
         to this Agreement shall pay its own costs of and incidental to this
         Agreement and the sale and purchase hereby agreed to be made, whether

                  appearing at the beginning and end of the communication,

14.4     SEVERABILITY: If any term or other provision of this Agreement is
         invalid, illegal or incapable of being enforced by any law or public
         policy, all other terms and provisions of this Agreement shall
         nevertheless remain in full force and effect so long as the economic or
         legal substance of the transactions contemplated hereby is not affected
         in any manner materially adverse to any party. Upon any determination
         that any term or other provision is invalid, illegal or incapable of
         being enforced, the parties hereto shall negotiate in good faith to
         modify this Agreement so as to effect the original intent of the
         parties as closely as possible in an acceptable manner in order that
         the transactions contemplated by this Agreement are effected as
         originally contemplated to the greatest extent possible.

14.5     ASSIGNMENT: This Agreement shall be binding upon and enure to the
         benefit of the successors of the parties but shall not be assignable by
         either the Sellers or the Purchasers without the express written
         consent of the other parties (which consent may be granted or withheld
         in the sole discretion of such other parties) provided however that the
         Purchasers may assign this Agreement to an Affiliate of AerCo without
         the consent of the Sellers.

14.6     AMENDMENT: This Agreement may not be amended except (a) by an
         instrument in writing signed by or on behalf of the Sellers and the
         Purchasers or (b) by a waiver in accordance with clause 14.1 hereof.

14.7     APPLICABLE LAW AND JURISDICTION:

         (a)      This Agreement shall be governed by and construed in
                  accordance with the laws of Ireland, except that the
                  Warranties relating to AerFi POL set out in Part 2 of Schedule
                  3 and the definition of "SOLVENCY" as it relates to AerFi POL
                  shall be interpreted in accordance with the laws of the State
                  of New York.

         (b)      Each of the parties hereby submits to the non-exclusive
                  jurisdiction of the courts of Ireland. The Purchasers hereby
                  irrevocably:-

                  (i)      waive any objections on the ground of venue or forum
                           non conveniens or any similar grounds; and

                  (ii)     consent to service of process by mail or in any other
                           manner permitted by applicable law.

         (c)      Each Purchaser and each Seller shall at all times maintain an
                  agent for service of process in Ireland. Each Purchaser and
                  each Seller appoints AerFi Administrative Services Limited, of
                  Aviation House, Shannon, Co Clare, Ireland, Attn: Company
                  Secretary, as such agent. Any writ, judgement or other notice
                  of legal process issued out of the courts in Ireland in
                  respect of this Agreement shall be sufficiently served on a
                  Purchaser or Seller if delivered to such agent at its address
                  for the time being. Each Purchaser and each Seller undertakes
                  not to revoke the authority of the above agent and if, for any
                  reason, such agent no longer serves as agent of a Purchaser or
                  Seller, that Purchaser or Seller shall promptly appoint
                  another such agent and advise the other parties thereof.

14.8     SURVIVAL AFTER CLOSING: The provisions of this Agreement in so far as
         the same shall not have been performed at any Closing shall remain in
         full force and effect notwithstanding such Closing.

14.9     COUNTERPARTS: This Agreement may be executed in one or more
         counterparts and by the different parties hereto in separate
         counterparts, each of which when executed shall be deemed to be an
         original but all of which taken together shall constitute one and the
         same agreement.

                           PURCHASE PRICE ADJUSTMENTS

                            SHARE PURCHASE AGREEMENT

For each of the first 15 Aircraft which are delivered by the Sellers to the
Purchasers, the allocable amount (Schedule 1 - Column V) which would otherwise
be paid from the Aircraft Purchase Account to or at the direction of the
relevant Sellers for such Aircraft will be reduced pursuant to the Adjustment
Delivery Factor Schedule (Schedule 2) and the principal amount of the E Notes
allocable to such Aircraft (Schedule 1 - Column VII) will be increased by the
amount of such reduction.

In the case of each Aircraft to be delivered by the Sellers to the Purchasers
after delivery of the first 15 Aircraft, the allocable amount to be paid from
the Aircraft Purchase Account to or at the direction of the relevant sellers for
such Aircraft shall be increased, as described in the following paragraph, such
that the cumulative reduction in amounts paid out of the Aircraft Purchase
Account on the delivery of the first 15 Aircraft will be fully recouped over the
delivery of the remaining Aircraft (assuming all 30 Aircraft are delivered) with
a reduction in the aggregate principal amount of the E Notes allocable to those
Aircraft (Schedule 1 - Column VII) of the same amount.

On delivery of each Aircraft delivered after delivery of the first 15 Aircraft,
the allocable amount which would otherwise be paid from the Aircraft Purchase
Account for such Aircraft to or at the direction of the relevant Sellers
(Schedule 1 - Column V) will be increased by an amount which is equal to the
product of (i) the total reduction in the amount payable from the Aircraft
Purchase Account for the first 15 Aircraft as described in the first paragraph
hereof and (ii) a fraction, the numerator of which is that Aircraft's Initial
Appraised Value and the denominator of which is the overall appraised value of
the last 15 Aircraft scheduled to be delivered (assuming all 30 Aircraft will be
delivered) as described in the first paragraph hereof, provided however that an
amount equal to the aggregate amount of the reductions made pursuant to the
first paragraph hereof (net of any Rebates paid as of that date) shall be
transferred from the Aircraft Purchase Account to the Collection Account upon a
Non-Delivery Event described in Clause 7.1(b) of the Share Purchase Agreement or
a Non-Delivery Event described in Clause 7.1(a) of the Share Purchase Agreement
with respect to the last Remaining Aircraft. The E Notes allocable to such
Aircraft (Schedule 1 - Column VII) will be reduced by the same amount.

In no case shall the overall A-E Notes allocable to any Aircraft be more or less
than the relevant Aircraft's appraised value.

         The entry into and performance by each Seller of this Agreement, and
         the transactions contemplated hereby, do not and will not conflict with

         (b)      the constitutional documents of such Seller or any of the

                  (ii)     To the knowledge of such Seller(s) no other material
                           Events of Default under any Lease (or, where

                  Lease with respect to which certificates of airworthiness are
                  not in force; and, based on the existence of such certificates
                  of airworthiness, the Sellers have no reason to believe that

                  defined in the relevant Lease); and

                  understandings with respect to such Aircraft or all of the
                  Aircraft taken as a whole, which would materially affect the

         licensed or qualified to do business and is in good standing in each

                  respect of any event occurring after Closing in circumstances

                           consideration deemed to have been received for
                           taxation purposes; or

                  obligations hereunder; or

4.       CLAIMS

4.1      NOTICE BY PURCHASERS: TIME LIMIT ON CLAIMS: No claim shall be brought

         Company shall forthwith give written notice thereof to the Covenantors
         and shall (if the Covenantors shall indemnify and secure the Company to
         its reasonable satisfaction against all losses, costs, damages and
         expenses including interest on overdue tax which may be incurred
         thereby) take such action as the Covenantors may reasonably and

         Covenantors shall be obliged to pay to the relevant Purchaser such sums
         as will after such deduction or withholding has been made leave the
         Purchaser with the same amount as they would have been entitled to
         receive in the absence of any such requirement to make a deduction or
         withholding. If any sum payable by the Covenantors to the relevant
         Purchaser under this Deed shall otherwise be subject to tax in the
         hands of the relevant Purchaser the same obligation to make an
         increased payment shall apply in relation to such tax liability as if
         it were a deduction or withholding required by law. The Purchasers and
         the Covenantors hereby undertake to co-operate to avoid or to minimise
         any such grossing up where possible at no extra cost to the Purchasers
         or the Covenantors.

         Companies may release or compromise the liability of any of the

3.       On the date hereof, both before and after giving effect to the
         Transactions, the Company will be able to pay its debts and other
         Liabilities, contingent obligations and other commitments as they
         mature in the normal course of business.

4.       On the date hereof, both before and after giving effect to the
         Transactions, the Company is not engaged in any business or any
         transaction, and is not about to engage in any business or any
         transaction, for which its property would constitute unreasonably small
         capital.

5.       The Company does not intend to, and does not believe that it will incur
         debts and liabilities that will be beyond its ability to pay such debts
         or liabilities as they mature.

6.       In consummating the Transactions, the Company does not intend to
         hinder, delay or defraud either present or future creditors or any
         other Person to which the Company is or will become, on or after the
         date hereof, indebted.

7.       In reaching the conclusions set forth in this certificate, the Company
         has considered, among other things (both before and after giving effect
         to the Transactions):-

         (c)      the cash and other current assets of or available to the
                  Company, determined after giving effect, on a pro forma basis,
                  to the Transaction;

         (d)      all contingent liabilities of the Company including, without
                  limitation, claims arising out of pending or threatened
                  litigation, and in so doing, the Company has computed the
                  amount of such liabilities as the amount which, in light of
                  all the facts and circumstances existing on the date hereof,
                  represents the amount that would reasonably be expected to
                  become an actual or matured liability (the "CONTINGENT
                  LIABILITIES"); and

         (e)      such other financial, statistical and other data known to it
                  and believed by it to be relevant for the purpose of this
                  certificate.

IN WITNESS WHEREOF, I have executed this certificate for and on behalf of [ ] on
the ____________ day of ____________________, 2000.
