     Memorandum, in the form used by the Initial Purchasers to confirm sales and
     on the Closing Date, will not contain any untrue statement of a material

     duly qualified to transact business and in good standing (in each
     jurisdiction in which such concept applies) in each jurisdiction in which
     the ownership or leasing of its properties and the conduct of its business
     requires such qualification, except to the extent that the failure to be so
     qualified or to be in good standing (in each jurisdiction in which such
     concept applies) would not have a material adverse effect on the financial
     condition, results of operations or business of any Transferring Company or
     of the AerFi Companies, taken as a whole, and each AerFi Company has the
     corporate power and authority to own or hold its property and to conduct

          (c) no liquidator, provisional liquidator, official manager, examiner,
     trustee, receiver or administrative receiver and manager or similar officer

     Company, nor has any application been made by any of the AerFi Companies
     or, to the best of AerFi's knowledge, by any third party to a court which
     is still pending for an order for, or any act, matter or thing been done
     which, with the giving of notice, lapse of time or satisfaction of some
     other condition (or any combination thereof), will lead to the appointment
     of any such officers or the equivalent in any jurisdiction; after giving
     effect to the transfer of the Transferring Companies, AerFi will be solvent
     for purposes of Section 214 of the Ireland Companies Act, 1963 (as amended)

     or will have been as of the relevant Transfer Date duly authorized,
     executed and delivered by such of the AerFi Companies as are or will be
     party thereto and constitutes or thereupon will constitute a valid and
     binding agreement of such AerFi Company, enforceable against such AerFi
     Company in accordance with its terms, except as (i) the enforceability
     thereof may be limited by bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and other similar laws affecting creditors'
     rights generally, (ii) rights of acceleration, if applicable, and the
     availability of equitable remedies may be limited by equitable principle of

     Company is a party or by which any such AerFi Company is bound, or to which
     any of the properties or assets of any such AerFi Company is subject (other
     than those created under the Security Documents), nor will such actions
     result in any violation of, or conflict with, the provisions of the
     constitutional documents of any such AerFi Company or any statute, order,
     decree, rule or regulation of any court or governmental agency or body
     having proper jurisdiction over any AerFi Company or any of their

     prevent the consummation of any of the transactions contemplated by this

its own expense, to the Initial Purchasers, amendments or supplements to such

     7. Offering of Notes; Restrictions on Transfer. (a) Each Initial Purchaser,
severally and not jointly, represents and warrants that such Initial Purchaser
is a

                                       18
<PAGE>   19

qualified institutional buyer as defined in Rule 144A under the Securities
Act (a "QIB"). Each Initial Purchaser, severally and not jointly, agrees with
the Issuer that (i) it will not solicit offers for, or offer or sell, such Notes
by any form of general solicitation or general advertising (as those terms are
used in Regulation D under the Securities Act) or in any manner involving a
public offering within the meaning of Section 4(2) of the Securities Act and
(ii) it will solicit offers for such Notes only from, and will offer such Notes
only to, persons that it reasonably believes to be (A) in the case of offers
inside the United States, QIBs and (B) in the case of offers outside the United
States, to persons other than U.S. persons ("FOREIGN PURCHASERS," which term
shall include dealers or other professional fiduciaries in the United States
acting on a discretionary basis for foreign beneficial owners (other than an
estate or trust)) that, in each case, in purchasing such Notes are deemed to
have represented and agreed as provided in the Final Memorandum under the
caption "Purchasers' Representations and Transfer Restrictions."

     (b) Each Initial Purchaser, severally and not jointly, represents,
warrants, and agrees with respect to offers and sales outside the United States
that:

          (i) it understands that no action has been or will be taken in any
     jurisdiction by the Issuer that would permit a public offering of the
     Notes, or possession or distribution of either Memorandum or any other
     offering or publicity material relating to the Notes, in any country or
     jurisdiction where action for that purpose is required;

          (ii) it will comply with all applicable laws and regulations in each
     jurisdiction in which it acquires, offers, sells or delivers Notes or has
     in its possession or distributes either Memorandum or any such other
     material, in all cases at its own expense;

          (iii) the Notes have not been and will not be registered under the
     Securities Act and may not be offered or sold within the United States or
     to, or for the account or benefit of, U.S. persons except in accordance
     with Regulation S under the Securities Act or pursuant to an exemption from
     the registration requirements of the Securities Act;

          (iv) it has offered the Notes and will offer and sell the Notes (A) as
     part of their distribution at any time and (B) otherwise until 40 days
     after the later of the commencement of the offering of the Notes and the
     Closing Date, only in accordance with Rule 903 of Regulation S or another
     exemption from the registration requirements of the Securities Act and it
     has sent to any dealer to whom it sells Notes during such 40-day period a
     notice setting forth the restrictions on offers and sales of the Notes
     within the United States or to or for U.S. persons; accordingly, neither
     such Initial Purchaser, its Affiliates nor any persons acting on its or
     their behalf have engaged or will engage in any directed selling efforts
     (within the meaning of Regulation S) with respect to the Notes, and any
     such Initial Purchaser, its Affiliates and any such persons have complied
     and will comply with the offering restrictions requirements of Regulation
     S;

          (v) it has (A) not offered or sold and, prior to six months after the
     Closing Date, will not offer or sell any Notes to persons in the United
     Kingdom except to persons whose ordinary activities involve them in
     acquiring, holding, managing or disposing of investments (as principal or
     agent) for the purposes of their businesses or

                                       19
<PAGE>   20

     otherwise in circumstances which have not resulted and will not result in
     an offer to the public in the United Kingdom within the meaning of the
     Public Offers of Securities Regulations 1995 (the "REGULATIONS"); (B)
     complied and will comply with all applicable provisions of the Financial
     Services Act 1986 and the Regulations with respect to anything done by it
     in relation to the Notes in, from or otherwise involving the United
     Kingdom; and (C) only issued or passed on and will only issue or pass on to
     any person in the United Kingdom any document received by it in connection
     with the issue of the Notes if that person is of a kind described in
     Article 11(3) of the Financial Services Act 1986 (Investment
     Advertisements) (Exemptions) Order 1996 or is a person to whom such
     document may otherwise lawfully be issued or passed on;

          (vi) it has not offered or sold and will not offer or sell any of the
     Notes in Ireland by means of any document in circumstances which constitute
     an offer to the public within the meaning of the Companies Acts, 1963 to
     1990, of Ireland and has not made and will not at any time make any offer
     of any of the Notes in Ireland to which the European Communities
     (Transferable Securities and Stock Exchange Regulations) 1992 of Ireland
     would apply; and it will not underwrite the issue of or place the Notes
     otherwise than in accordance with the provisions of the Irish Investment
     Intermediaries Act, 1995, including, without limitation, Sections 9, 23
     (including any advertising restrictions made thereunder) and 50 and any
     codes of conduct made under Section 37;

          (vii) it will not undertake any directed selling efforts with respect
     to the Notes in Jersey other than to financial institutions which may
     acquire Notes in the normal course of their trade;

          (viii) it understands that in Ireland the Notes may only be offered,
     transferred, delivered or sold to individuals or legal entities who or
     which trade or invest in securities in the conduct of their profession or
     trade, which include banks, brokers, dealers, insurance companies, pension
     funds and other institutional investors, and commercial enterprises which
     regularly, as an ancillary activity, invest in securities;

          (ix) it understands that the Notes have not been and will not be
     registered under the Securities and Exchange Law of Japan, and represents
     that it has not offered or sold, and agrees that it will not offer or sell,
     any Notes, directly or indirectly in Japan or to any resident of Japan
     except (A) pursuant to an exemption from the registration requirements of
     the Securities and Exchange Law of Japan and (B) in compliance with any
     other applicable requirements of Japanese law;

          (x) it has not offered or sold, and it will not offer or sell, the
     Notes by means of any document to persons in Hong Kong other than persons
     whose ordinary business it is to buy or sell shares or debentures, whether
     as principal or agent, or otherwise in circumstances which do not
     constitute an offer to the public within the meaning of the Hong Kong
     Companies Ordinance (Chapter 32 of the Laws of Hong Kong); and

          (xi) such Initial Purchaser has acknowledged that the Offering
     Memorandum has not been registered with the Registrar of Companies in
     Singapore and that the Notes are issued in Singapore pursuant to an
     exemption invoked under section 106C of the Companies Act, Chapter 50 of
     Singapore (the "SINGAPORE

                                       20
<PAGE>   21

     COMPANIES ACT"); accordingly, each of the Initial Purchasers has
     represented and agreed that the Notes issued in Singapore may not be
     offered or sold, nor may the Offering Memorandum or any other offering
     document or material relating to the Notes to be circulated or distributed,
     directly or indirectly, to the public or any member of the public in
     Singapore other than (A) to an institutional investor or other body or
     person specified in section 106C of the Singapore Companies Act, (B) to a
     sophisticated investor or other body or person specified in section 106D of
     the Singapore Companies Act, or (C) otherwise pursuant to, and in
     accordance with the conditions of, section 106E(2) of the Singapore
     Companies Act or any other applicable exemption invoked under Division 5A
     of Part IV of the Singapore Companies Act.

Terms used in this Section 7 have the meanings given to them by Regulation S.

     8. Indemnification and Contribution. (a) Each of the Issuer and AerFi
agrees to jointly and severally indemnify and hold harmless each Initial
Purchaser, and each person, if any, who controls (a "CONTROL PERSON") such
Initial Purchaser within the meaning of either Section 15 of the Securities Act
or Section 20 of the Exchange Act, or is under common control with, or is
controlled by, such Initial Purchaser, and each of their respective directors,
officers, employees or agents from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred by any Initial Purchaser or any such control person
in connection with defending or investigating any such action or claim) caused
by any untrue or misleading statement or alleged untrue or misleading statement
of a material fact contained in either Memorandum (as amended or supplemented if
the Issuer shall have furnished any amendments or supplements thereto), or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein in the
light of the circumstances under which they were made not misleading, except
insofar as such losses, claims, damages or liabilities are caused by any such
untrue statement or omission or alleged untrue statement or omission based upon
information relating to any Initial Purchaser furnished to the Issuer in writing
by such Initial Purchaser through the Representatives expressly for use therein;
provided, however, that the foregoing indemnity of AerFi shall be limited to the
AerFi Information.

     (b) Each Initial Purchaser agrees, severally and not jointly, to indemnify
and hold harmless each of the Issuer and AerFi and its respective directors and
its officers and each person, if any, who controls (a "CONTROL PERSON") either
the Issuer or AerFi, in each case to the same extent as the foregoing indemnity
from the Issuer and AerFi to such Initial Purchaser, but only with reference to
information relating to such Initial Purchaser furnished to the Issuer in
writing by such Initial Purchaser through the Representatives expressly for use
in either Memorandum or any amendments or supplements thereto.

     (c) In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to either Section 8(a) or 8(b), such person (the "INDEMNIFIED PARTY")
shall promptly notify the person against whom such indemnity may be sought (the
"INDEMNIFYING PARTY") in writing and the indemnifying party, upon request of the
indemnified party, shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses

                                       21
<PAGE>   22

of such counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all such
indemnified parties and that all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by Morgan Stanley &
Co. International Limited in the case of parties indemnified pursuant to Section
8(a) and by each of the Issuer and AerFi in the case of parties indemnified
pursuant to Section 8(b). The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

     (d) To the extent the indemnification provided for in Section 8(a) or 8(b)
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities, then each indemnifying party under such
paragraph, in lieu of indemnifying such indemnified party thereunder, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Issuer and AerFi,
on the one hand, and the Initial Purchasers, on the other hand, from the
offering of such Notes or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Issuer and AerFi on the one hand and the Initial
Purchasers on the other hand in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Issuer
and AerFi on the one hand and the Initial Purchasers on the other hand in
connection with the offering of such Notes shall be deemed to be in the same
respective proportions as the net proceeds from the offering of such Notes
(before deducting expenses) received by the Issuer and AerFi and the total
discounts and commissions received by the Initial Purchasers in respect thereof
bear to the aggregate offering price of such Notes. The relative fault of the
Issuer and AerFi on the one hand and of the Initial Purchasers on the other hand
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Issuer or AerFi
or by the Initial Purchasers and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Initial Purchasers' respective obligations to contribute pursuant to this
Section 8 are several in proportion to the respective principal amount of Notes
they have purchased hereunder, and not joint.

     (e) The Issuer, AerFi and the Initial Purchasers agree that it would not be
just or equitable if contributions pursuant to this Section 8 were determined by
pro rata

                                       22
<PAGE>   23

allocation (even if the Initial Purchasers were treated as one entity for such
purpose) or by any other method of allocation that does not take into account
the equitable considerations referred to in Section 8(d). The amount paid or
payable by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in Section 8(d) shall be deemed to include, subject to
the limitations set forth above, any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 8, no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Notes resold by it in the initial placement
of such Notes were offered to investors exceeds the amount of any damages that
such Initial Purchaser has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The indemnity and contribution
provisions contained in this Section 8 and the representations, warranties and
agreements of the Issuer and AerFi contained in this Agreement shall remain
operative and in full force and effect regardless of (i) any termination of this
Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers
or any control person with respect to any Initial Purchaser or by or on behalf
of the Issuer or AerFi, its respective officers or directors or any control
person with respect to the Issuer or AerFi and (iii) acceptance of and payment
for any of the Notes. The remedies provided for in this Section 8 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

     9. Termination. This Agreement shall be subject to termination by notice
given by the Representatives to the Issuer, if (a) after the execution and
delivery of this Agreement and prior to the Closing Date (i) trading generally
shall have been suspended or materially limited on or by, as the case may be,
any of the New York Stock Exchange, the American Stock Exchange, the London
Stock Exchange, the National Association of Securities Dealers, Inc., the
Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago
Board of Trade or the Luxembourg Stock Exchange, (ii) trading of any securities
of the Issuer, AerFi or debis shall have been suspended on any exchange or in
any over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York shall have been declared by either federal or New York
State authorities or in London by the relevant London or United Kingdom
authorities or (iv) there shall have occurred any outbreak or escalation of
hostilities or any change in financial markets or any calamity or crisis that,
in the Representatives' judgment, is material and adverse and (b) in the case of
any of the events specified in clauses (a)(i) through (iv) of this Section 9,
such event singly or together with any other such event makes it, in the
Representatives' judgment, impracticable to market the Notes on the terms and in
the manner contemplated in the Final Memorandum.

     10. Submission to Jurisdiction; Appointment of Agent for Service;
Obligation Currency. Any suit, action or proceeding against any party to this
Agreement arising out of or relating to this Agreement, any Relevant Document or
any transaction contemplated hereby or thereby or any judgment entered by any
court in respect thereof may be brought in any New York State court located in
the County of New York or federal court sitting in the Second Circuit, and each
such party hereby submits to the nonexclusive jurisdiction of such courts for
the purpose of any such suit, action or proceeding. To the extent that service
of process by mail is permitted by applicable law, each party hereto irrevocably
consents to the service of process in any such suit, action or proceeding in
such

                                       23
<PAGE>   24

courts by the mailing of such process by registered or certified mail, postage
prepaid, at its address for notices provided above. Each party to this Agreement
irrevocably agrees not to assert any objection which it may ever have to the
laying of venue of any such suit, action or proceeding in any New York State
court located in the County of New York or federal court sitting in the Second
Circuit, and any claim that any such suit, action or proceeding brought in any
such court has been brought in an inconvenient forum. The Issuer hereby
irrevocably designates and appoints Corporation Service Company, 375 Hudson
Street, New York, New York 10014-3660, and AerFi hereby irrevocably designates
and appoints AerFi Corporation, 100 NE 3rd Avenue, Suite 800, Ft. Lauderdale,
Florida 00001 as its authorized agent (each, a "PROCESS AGENT"), upon whom
process may be served in any such suit or proceeding, it being understood that
such designation and appointment shall become effective immediately without any
further action on the part of the Issuer or AerFi. Each of the Issuer and AerFi
hereby represents to each Initial Purchaser that it has notified its Process
Agent of such designation and appointment and that such Process Agent has
accepted the same in writing. Each of the Issuer and AerFi hereby irrevocably
authorizes and directs its Process Agent to accept such service. Each of the
Issuer and AerFi further agrees that service of process upon its respective
Process Agent and written notice of such service to the Issuer or AerFi, as the
case may be, mailed by first class mail or delivered to its respective Process
Agent, shall be deemed in every respect effective service of process upon the
Issuer or AerFi, as the case may be, in any such suit or proceeding. Nothing
herein shall affect the right of any Initial Purchaser or any control person
with respect to any Initial Purchaser to serve process in any other manner
permitted by law. Each of the Issuer and AerFi agrees that a final action in any
such suit or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other lawful manner.

     11. Miscellaneous. If, on the Closing Date, any one or more of the Initial
Purchasers shall fail or refuse to purchase Notes that it or they have agreed to
purchase hereunder on such date, and the aggregate principal amount of Notes
which such defaulting Initial Purchaser or Initial Purchasers agreed but failed
or refused to purchase is not more than one-tenth of the aggregate principal
amount of Notes to be purchased on such date, the other Initial Purchasers shall
be obligated severally in the proportions that the principal amount of Notes set
forth opposite their respective names in Schedule I bears to the aggregate
principal amount of Notes set forth opposite the names of all such
non-defaulting Initial Purchasers, or in such other proportions as the
Representatives may specify, to purchase the Notes which such defaulting Initial
Purchaser or Initial Purchasers agreed but failed or refused to purchase on such
date; provided that in no event shall the principal amount of Notes that any
Initial Purchaser has agreed to purchase pursuant to Section 4 be increased
pursuant to this Section 11 by an amount in excess of one-ninth of such
principal amount of Notes without the written consent of such Initial Purchaser.
If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail
or refuse to purchase Notes which it or they have agreed to purchase hereunder
on such date and the aggregate principal amount of Notes with respect to which
such default occurs is more than one-tenth of the aggregate principal amount of
Notes to be purchased on such date and arrangements satisfactory to the
Representatives and the Issuer and AerFi for the purchase of such Notes are not
made within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Initial Purchaser or of the Issuer
or AerFi. In any such case either the Representatives or the Issuer shall have
the right to postpone the Closing Date, but in no event for longer than seven
days, in order that the required changes, if any, in the Final Memorandum or in
any other documents or arrangements may be effected. Any action taken

                                       24
<PAGE>   25
under this paragraph shall not relieve any defaulting Initial Purchaser from
liability in respect of any default of such Initial Purchaser under this
Agreement.

     This Agreement may be signed in any number of counterparts, each of which
shall be an original, with the same effect as if the signatures thereto and
hereto were upon the same instrument.

     If this Agreement shall be terminated by the Initial Purchasers, or any of
them, because of any failure or refusal on the part of the Issuer or AerFi to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason the Issuer or AerFi shall be unable to perform its obligations
under this Agreement, the Issuer and AerFi shall jointly and severally reimburse
the Initial Purchasers or such Initial Purchasers as have so terminated this
Agreement with respect to themselves, severally, for all out-of-pocket expenses
(including the fees and disbursements of their counsel) reasonably incurred by
such Initial Purchasers in connection with this Agreement or the offering
contemplated hereunder.

case including the Prospectus

contained therein, all exhibits thereto and all material incorporated by
reference therein.

     "TRUSTEE" shall mean the trustee with respect to the Notes under the
Indenture.

     "UNDERWRITTEN REGISTRATION" or "UNDERWRITTEN OFFERING" shall mean a
registration in which Registrable Notes are sold to an Underwriter (as
hereinafter defined) for reoffering to the public.

     2. Registration Under the 1933 Act.

     (a) To the extent not prohibited by any applicable law or applicable
interpretation of the Staff of the SEC, the Issuer shall use its best efforts to
cause to be filed an Exchange Offer Registration Statement covering the offer by
the Issuer to the Holders to exchange all of the Registrable Notes for Exchange
Notes and to have such Registration Statement remain effective until the closing
of the Exchange Offer. The Issuer shall commence the Exchange Offer promptly
after the Exchange Offer Registration Statement has been declared effective by
the SEC and use its best efforts to have the Exchange Offer consummated not
later than 60 days after such effective date. The Issuer shall commence the
Exchange Offer by mailing the related exchange offer Prospectus and accompanying
documents to each Holder stating, in addition to such other disclosures as are
required by applicable law:

     (i) that the Exchange Offer is being made pursuant to this Agreement and
that all Registrable Notes validly tendered will be accepted for exchange;

     (ii) the dates of acceptance for exchange (which shall be a period of not
less than 20 business days commencing from the date such notice is mailed) (the
"EXCHANGE DATES");

     (iii) that any Registrable Security not tendered will remain outstanding
and continue to accrue interest, but will not retain any rights under this
Agreement;

     (iv) that Holders electing to have a Registrable Security exchanged
pursuant to the Exchange Offer will be required to surrender such Registrable
Security, together with the enclosed letters of transmittal, to the institutions
and at the addresses (located in the Borough of Manhattan, The City of New York
and in Luxembourg) specified in the notice prior to the close of business on the
last Exchange Date; and

     (v) that Holders will be entitled to withdraw their election, not later
than the close of business on the last Exchange Date, by sending to the
applicable institution and at the address (located in either the Borough of
Manhattan, The City of New York or Luxembourg) specified in the notice a
telegram, telex, facsimile transmission or letter setting forth the name of such
Holder, the principal amount of Registrable Notes delivered for exchange and a
statement that such Holder is withdrawing his election to have such Notes
exchanged.

     As soon as practicable after the last Exchange Date, the Issuer shall:

                                      A-4
<PAGE>   39

          (i) accept for exchange Registrable Notes or portions thereof tendered
     and not validly withdrawn pursuant to the Exchange Offer; and

          (ii) deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Notes or portions thereof so accepted for
     exchange by the Issuer and issue, and cause the Trustee to promptly
     authenticate and mail to each Holder, Exchange Notes equal in principal
     amount to the principal amount of the Registrable Notes surrendered by such
     Holder.

     The Issuer shall use its best efforts to complete the Exchange Offer as
provided above and shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws and regulations in connection with
the Exchange Offer. The Exchange Offer shall not be subject to any conditions,
other than that the Exchange Offer does not violate applicable law or any
applicable interpretation of the Staff of the SEC. The Issuer shall inform the
Representatives of the names and addresses of the Holders to whom the Exchange
Offer is made, and the Representatives shall have the right, subject to
applicable law, to contact such Holders and otherwise facilitate the tender of
Registrable Notes in the Exchange Offer.

     (b) In the event that (i) the Issuer determines that the Exchange Offer
Registration provided for in Section 2(a) above is not available or may not be
consummated as soon as practicable after the last Exchange Date because it would
violate applicable law or the applicable interpretations of the Staff of the
SEC, (ii) the Exchange Offer is not for any other reason consummated by the date
that is 270 days after the Closing Date or (iii) the Exchange Offer has been
completed and in the opinion of counsel for the Initial Purchasers a
Registration Statement must be filed and a Prospectus must be delivered by the
Representatives in connection with any offering or sale of Registrable Notes,
the Issuer shall use its best efforts to cause to be filed as soon as
practicable after such determination, date or notice of such opinion of counsel
is given to the Issuer, as the case may be, a Shelf Registration Statement
providing for the sale by the Holders of all of the Registrable Notes and to
have such Shelf Registration Statement declared effective by the SEC. The Issuer
agrees to use its best efforts to keep the Shelf Registration Statement
continuously effective until the second anniversary of the Closing Date or such
shorter period that will terminate when all of the Registrable Notes covered by
the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement. The Issuer further agrees to supplement or amend the
Shelf Registration Statement if required by the rules, regulations or
instructions applicable to the registration form used by the Issuer for such
Shelf Registration Statement or by the 1933 Act or by any other rules and
regulations thereunder for shelf registration or if reasonably requested by a
Holder with respect to information relating to such Holder, and to use its best
efforts to cause any such amendment to become effective and such Shelf
Registration Statement to become usable as soon as thereafter practicable. The
Issuer agrees to furnish to the Holders of Registrable Notes copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

     (c) The Issuer shall pay all Registration Expenses in connection with the
registration pursuant to Section 2(a) or Section 2(b). Each Holder shall pay all
underwriting discounts and commissions and transfer taxes, if any, relating to
the sale or disposition of such Holder's Registrable Notes pursuant to the Shelf
Registration Statement.

                                      A-5
<PAGE>   40

     (d) An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared effective by
the SEC; provided, however, that, if, after it has been declared effective, the
offering of Registrable Notes pursuant to a Shelf Registration Statement is
interfered with by any stop order, injunction or other order or requirement of
the SEC or any other governmental agency or court, such Registration Statement
will be deemed not to have become effective during the period of such
interference until the offering of Registrable Notes pursuant to such
Registration Statement may legally resume. As provided for in the Indenture,
from and after the date that is 270 days after the Closing Date, the interest
rate on each subclass of Notes will be increased by 0.50% per annum until the
completion of an Exchange Offer or the date a Shelf Registration Statement is
declared effective by the SEC, whereupon the interest rate on each subclass of
Notes will permanently decrease to the applicable interest rate provided for
such subclass of Note.

     (e) Without limiting the remedies available to the Representatives and the
Holders, the Issuer acknowledges that any failure by the Issuer to comply with
its obligations under Section 2(a) and Section 2(b) hereof may result in
material irreparable injury to the Representatives or the Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Representatives or any Holder may obtain such relief as may be required to
specifically enforce the Issuer's obligations under Section 2(a) and Section
2(b) hereof.

     3. Registration Procedures.

     In connection with the obligations of the Issuer with respect to the
Registration Statements pursuant to Section 2(a) and Section 2(b) hereof, the
Issuer shall as expeditiously as possible:

          (a) prepare and file with the SEC a Registration Statement on the
     appropriate form under the 1933 Act, which form (x) shall be selected by
     the Issuer and (y) shall, in the case of a Shelf Registration, be available
     for the sale of the Registrable Notes by the selling Holders thereof and
     (z) shall comply as to form in all material respects with the requirements
     of the applicable form and include all financial statements required by the
     SEC to be filed therewith, and use its best efforts to cause such
     Registration Statement to become effective and remain effective in
     accordance with Section 2 hereof;

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to each Registration Statement as may be necessary to keep such
     Registration Statement effective for the applicable period and cause each
     Prospectus to be supplemented by any required prospectus supplement and, as
     so supplemented, to be filed pursuant to Rule 424 under the 1933 Act; to
     keep each Prospectus current during the period described under Section 4(3)
     and Rule 174 under the 1933 Act that is applicable to transactions by
     brokers or dealers with respect to the Registrable Notes or Exchange Notes;

          (c) in the case of a Shelf Registration, furnish to each Holder of
     Registrable Notes, to counsel for the Representatives, to counsel for the
     Holders and to each Underwriter of an Underwritten Offering of Registrable
     Notes, if any, without

                                      A-6
<PAGE>   41

     charge, as many copies of each Prospectus, including each preliminary
     Prospectus, and any amendment or supplement thereto and such other
     documents as such Holder or Underwriter may reasonably request, in order to
     facilitate the public sale or other disposition of the Registrable Notes;
     and the Issuer consents to the use of such Prospectus and any amendment or
     supplement thereto in accordance with applicable law by each of the selling
     holders of Registrable Notes and any such Underwriters in connection with
     the offering and sale of the Registrable Notes covered by and in the manner
     described in such Prospectus or any amendment or supplement thereto in
     accordance with applicable law;

          (d) use its best efforts to register or qualify the Registrable Notes
     under all applicable state securities or "blue sky" laws of such
     jurisdictions as any Holder of Registrable Notes covered by a Registration
     Statement shall reasonably request in writing by the time the applicable
     Registration Statement is declared effective by the SEC, to cooperate with
     such Holders in connection with any filings required to be made with the
     National Association of Securities Dealers, Inc. and do any and all other
     acts and things which may be reasonably necessary or advisable to enable
     such Holder to consummate the disposition in each such jurisdiction of such
     Registrable Notes owned by such Holder; provided, however, that the Issuer
     shall not be required to (i) qualify as a foreign corporation or as a
     dealer in securities in any jurisdiction where it would not otherwise be
     required to qualify but for this Section 3(d), (ii) file any general
     consent to service of process or (iii) subject itself to taxation in any
     such jurisdiction if it is not so subject;

          (e) in the case of a Shelf Registration, notify each Holder of
     Registrable Notes, counsel for the Holders and counsel for the
     Representatives promptly and, if requested by any such Holder or counsel,
     confirm such advice in writing (i) when a Registration Statement has become
     effective and when any post-effective amendment thereto has been filed and
     becomes effective, (ii) of any request by the SEC or any state securities
     authority for amendments and supplements to a Registration Statement and
     Prospectus or for additional information after the Registration Statement
     has become effective, (iii) of the issuance by the SEC or any state
     securities authority of any stop order suspending the effectiveness of a
     Registration Statement or the initiation of any proceedings for that
     purpose, (iv) if, between the effective date of a Registration Statement
     and the closing of any sale of Registrable Notes covered thereby, the
     representations and warranties of the Issuer contained in any underwriting
     agreement, securities sales agreement or other similar agreement, if any,
     relating to the offering cease to be true and correct in all material
     respects or if the Issuer receives any notification with respect to the
     suspension of the qualification of the Registrable Notes for sale in any
     jurisdiction or the initiation of any proceeding for such purpose, (v) of
     the happening of any event during the period a Shelf Registration Statement
     is effective which makes any statement made in such Registration Statement
     or the related Prospectus untrue in any material respect or which requires
     the making of any changes in such Registration Statement or Prospectus in
     order to make the statements therein not misleading and (vi) of any
     determination by the Issuer that a post-effective amendment to a
     Registration Statement would be appropriate;

          (f) make every reasonable effort to obtain the withdrawal of any order
     suspending the effectiveness of a Registration Statement at the earliest
     possible

                                      A-7
<PAGE>   42

     moment and provide immediate notice to each Holder of the withdrawal of any
     such order;

          (g) in the case of a Shelf Registration, furnish to each Holder of
     Registrable Notes, without charge, at least one conformed copy of each
     Registration Statement and any post-effective amendment thereto (without
     documents incorporated therein by reference or exhibits thereto, unless
     requested);

          (h) in the case of a Shelf Registration, cooperate with the selling
     Holders of Registrable Notes to facilitate the timely preparation and
     delivery of certificates representing Registrable Notes to be sold and not
     bearing any restrictive legends and enable such Registrable Notes to be in
     such denominations (consistent with the provisions of the Indenture) and
     registered in such names as the selling Holders may reasonably request at
     least two business days prior to the closing of any sale of Registrable
     Notes;

          (i) in the case of a Shelf Registration, upon the occurrence of any
     event contemplated by Section 3(e)(v) hereof, use its best efforts to
     prepare and file with the SEC a supplement or post-effective amendment to a
     Registration Statement or the related Prospectus or any document
     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable Notes,
     such Prospectus will not contain any untrue statement of a material fact or
     omit to state a material fact necessary to make the statements therein, in
     light of the circumstances under which they were made, not misleading; the
     Issuer agrees to notify the Holders to suspend use of the Prospectus as
     promptly as practicable after the occurrence of such an event, and the
     Holders hereby agree to suspend use of the Prospectus until the Issuer has
     amended or supplemented the Prospectus to correct such misstatement or
     omission;

          (j) a reasonable time prior to the filing of any Registration
     Statement, any Prospectus, any amendment to a Registration Statement or
     amendment or supplement to a Prospectus or any document which is to be
     incorporated by reference into a Registration Statement or a Prospectus
     after initial filing of a Registration Statement, provide copies of such
     document to the Representatives and their counsel (and, in the case of a
     Shelf Registration Statement, the Holders and their counsel) and make such
     of the Representatives of the Issuer as shall be reasonably requested by
     the Representatives or their counsel (and, in the case of a Shelf
     Registration Statement, the Holders or their counsel) available for
     discussion of such document, and shall not at any time file or make any
     amendment to the Registration Statement, any Prospectus or any amendment of
     or supplement to a Registration Statement or a Prospectus or any document
     which is to be incorporated by reference into a Registration Statement or a
     Prospectus, of which the Representatives and their counsel (and, in the
     case of a Shelf Registration Statement, the Holders and their counsel)
     shall not have previously been advised and furnished a copy or to which the
     Representatives or their counsel (and, in the case of a Shelf Registration
     Statement, the Holders or their counsel) shall object;

          (k) obtain a CUSIP number and such other identification numbers as may
     be necessary for all Exchange Notes or Registrable Notes, as the case may
     be, not later than the effective date of a Registration Statement;

                                      A-8
<PAGE>   43

          (l) use its best efforts to list the Exchange Notes, if any, on the
     Luxembourg Stock Exchange not later than the Effective Date of an Exchange
     Offer Registration Statement;

          (m) cause the Indenture to be qualified under the Trust Indenture Act
     of 1939, as amended (the "TIA"), in connection with the registration of the
     Exchange Notes or Registrable Notes, as the case may be, cooperate with the
     Trustee and the Holders to effect such changes to the Indenture as may be
     required for the Indenture to be so qualified in accordance with the terms
     of the TIA and execute, and use its best efforts to cause the Trustee to
     execute, all documents as may be required to effect such changes and all
     other forms and documents required to be filed with the SEC to enable the
     Indenture to be so qualified in a timely manner;

          (n) in the case of a Shelf Registration, make available for inspection
     by the Representatives of the Holders of the Registrable Notes, any
     Underwriter participating in any disposition pursuant to such Shelf
     Registration Statement, and attorneys and accountants designated by the
     Holders, at reasonable times and in a reasonable manner, all financial and
     other records, pertinent documents and properties of the Issuer, and cause
     the respective officers, directors and employees of the Issuer to supply
     all information reasonably requested by any such Representative,
     Underwriter, attorney or accountant in connection with a Shelf Registration
     Statement;

          (o) in the case of a Shelf Registration, use its best efforts to cause
     all Registrable Notes to be listed on any securities exchange or any
     automated quotation system on which similar securities issued by the Issuer
     are then listed if requested by the Majority Holders, to the extent such
     Registrable Notes satisfy applicable listing requirements;

          (p) use its best efforts to cause the Exchange Notes or Registrable
     Notes, as the case may be, to be rated by Standard Poor's Ratings Group,
     Moody's Investors Service, Inc. and Fitch Ratings Limited or two other
     nationally recognized statistical rating organizations (as such term is
     defined in Rule 436(g)(2) under the 1933 Act);

          (q) if reasonably requested by any Holder of Registrable Notes covered
     by a Registration Statement, (i) promptly incorporate in a Prospectus
     supplement or post-effective amendment such information with respect to
     such Holder as such Holder reasonably requests to be included therein and
     (ii) make all required filings of such Prospectus supplement or such
     post-effective amendment as soon as the Issuer has received notification of
     the matters to be incorporated in such filing; and

          (r) in the case of a Shelf Registration, enter into such customary
     agreements and take all such other actions in connection therewith
     (including those requested by the Holders of a majority of the Registrable
     Notes being sold) in order to expedite or facilitate the disposition of
     such Registrable Notes including, but not limited to, an Underwritten
     Offering and in such connection, (i) to the extent possible, make such
     representations and warranties to the Holders and any Underwriters of such
     Registrable Notes with respect to the business of the Issuer and its
     subsidiaries, the Registration Statement, Prospectus and documents
     incorporated by reference or deemed incorporated by reference, if any, in
     each case, in form, substance and scope

                                      A-9
<PAGE>   44

     as are customarily made by issuers to underwriters in underwritten
     offerings and confirm the same if and when requested, (ii) obtain opinions
     of counsel to the Issuer (which counsel and opinions, in form, scope and
     substance, shall be reasonably satisfactory to the Holders and such
     Underwriters and their respective counsel) addressed to each selling Holder
     and Underwriter of Registrable Notes, covering the matters customarily
     covered in opinions requested in underwritten offerings, (iii) obtain "cold
     comfort" letters from the independent certified public accountants of the
     Issuer (and, if necessary, any other certified public accountant of any
     subsidiary of the Issuer, or of any business acquired by the Issuer for
     which financial statements and financial data are or are required to be
     included in the Registration Statement) addressed to each selling Holder
     and Underwriter of Registrable Notes, such letters to be in customary form
     and covering matters of the type customarily covered in "cold comfort"
     letters in connection with underwritten offerings, and (iv) deliver such
     documents and certificates as may be reasonably requested by the Holders of
     a majority in principal amount of the Registrable Notes being sold or the
     Underwriters, and which are customarily delivered in underwritten
     offerings, to evidence the continued validity of the representations and
     warranties of the Issuer made pursuant to clause (i) above and to evidence
     compliance with any customary conditions contained in an underwriting
     agreement.

     In the case of a Shelf Registration Statement, the Issuer may require each
Holder of Registrable Notes to furnish to the Issuer such information regarding
the Holder and the proposed distribution by such Holder of such Registrable
Notes as the Issuer may from time to time reasonably request in writing.

     In the case of a Shelf Registration Statement, each Holder agrees that,
upon receipt of any notice from the Issuer of the happening of any event of the
kind described in Section 3(e)(v) hereof, such Holder will forthwith discontinue
disposition of Registrable Notes pursuant to a Registration Statement until such
Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof, and, if so directed by the Issuer, such
Holder will deliver to the Issuer (at its expense) all copies in its possession,
other than permanent file copies then in such Holder's possession, of the
Prospectus covering such Registrable Notes current at the time of receipt of
such notice. If the Issuer shall give any such notice to suspend the disposition
of Registrable Notes pursuant to a Registration Statement, the Issuer shall
extend the period during which the Registration Statement shall be maintained
effective pursuant to this Agreement by the number of days during the period
from and including the date of the giving of such notice to and including the
date when the Holders shall have received copies of the supplemented or amended
Prospectus necessary to resume such dispositions. The Issuer may give any such
notice only twice during any 365 day period and any such suspensions may not
exceed 30 days for each suspension and there may not be more than two
suspensions in effect during any 365 day period.

     The Holders of Registrable Notes covered by a Shelf Registration Statement
who desire to do so may sell such Registrable Notes in an Underwritten Offering.
In any such Underwritten Offering, the investment banker or investment bankers
and manager or managers (the "UNDERWRITERS") that will administer the offering
will be selected by the Majority Holders of the Registrable Notes included in
such offering.

     4. Participation of Broker-Dealers in Exchange Offer.

                                      A-10
<PAGE>   45

     (a) The Staff of the SEC has taken the position that any broker-dealer that
receives Exchange Notes for its own account in the Exchange Offer in exchange
for Notes that were acquired by such broker-dealer as a result of market-making
or other trading activities (a "PARTICIPATING BROKER-DEALER"), may be deemed to
be an "underwriter" within the meaning of the 1933 Act and must deliver a
prospectus meeting the requirements of the 1933 Act in connection with any
resale of such Exchange Notes.

     The Issuer understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Notes, without naming
the Participating Broker-Dealers or specifying the amount of Exchange Notes
owned by them, such Prospectus may be delivered by Participating Broker-Dealers
to satisfy their prospectus delivery obligation under the 1933 Act in connection
with resales of Exchange Notes for their own accounts, so long as the Prospectus
otherwise meets the requirements of the 1933 Act.

     (b) In light of the above, notwithstanding the other provisions of this
Agreement, the Issuer agrees that the provisions of this Agreement as they
relate to a Shelf Registration shall also apply to an Exchange Offer
Registration to the extent, and with such reasonable modifications thereto as
may be reasonably requested by the Representatives or by one or more
Participating Broker-Dealers, in each case as provided in clause (ii) below, in
order to expedite or facilitate the disposition of any Exchange Notes by
Participating Broker-Dealers consistent with the positions of the Staff recited
in Section 4(a) above; provided that:

          (i) the Issuer shall not be required to amend or supplement the
     Prospectus contained in the Exchange Offer Registration Statement, as would
     otherwise be contemplated by Section 3(i), for a period exceeding 180 days
     after the last Exchange Date (as such period may be extended pursuant to
     the penultimate paragraph of Section 3 of this Agreement) and Participating
     Broker-Dealers shall not be authorized by the Issuer to deliver and shall
     not deliver such Prospectus after such period in connection with the
     resales contemplated by this Section 4; and

          (ii) the application of the Shelf Registration procedures set forth in
     Section 3 of this Agreement to an Exchange Offer Registration, to the
     extent not required by the positions of the Staff of the SEC or the 1933
     Act and the rules and regulations thereunder, will be in conformity with
     the reasonable request to the Issuer by the Representatives or with the
     reasonable request in writing to the Issuer by one or more broker-dealers
     who certify to the Representatives and the Issuer in writing that they
     anticipate that they will be Participating Broker-Dealers; and provided
     further that, in connection with such application of the Shelf Registration
     procedures set forth in Section 3 to an Exchange Offer Registration, the
     Issuer shall be obligated (x) to deal only with one entity representing the
     Participating Broker-Dealers, which shall be the Representatives unless it
     elects not to act as such Representatives, (y) to pay the fees and expenses
     of only one counsel representing the Participating Broker-Dealers, which
     shall be counsel to the Representatives unless such counsel elects not to
     so act and (z) to cause to be delivered only one, if any, "cold comfort"
     letter with respect to the Prospectus in the form existing on the last
     Exchange Date and with respect to each subsequent amendment or supplement,
     if any, effected during the period specified in clause (i) above.

                                      A-11
<PAGE>   46

     (c) The Representatives shall have no liability to the Issuer or any Holder
with respect to any request that it may make pursuant to Section 4(b) above.

     5. Indemnification and Contribution.

     (a) The Issuer agrees to indemnify and hold harmless the Initial
Purchasers, each Holder and each person, if any, who controls any Initial
Purchaser or any Holder within the meaning of either Section 15 of the 1933 Act
or Section 20 of the 1934 Act, or is under common control with, or is controlled
by, any Initial Purchaser or any Holder, from and against all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred by any Initial Purchaser, any Holder or any such
controlling or affiliated person in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement (or any
amendment thereto) pursuant to which Exchange Notes or Registrable Notes were
registered under the 1933 Act, including all documents incorporated therein by
reference, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or caused by any untrue statement or alleged untrue
statement of a material fact contained in any Prospectus (as amended or
supplemented if the Issuer shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact necessary to make the statements therein in light of the
circumstances under which they were made not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to an Initial Purchaser or any Holder furnished to the Issuer in
writing by such Initial Purchaser through the Representatives or any selling
Holder expressly for use therein. In connection with any Underwritten Offering
permitted by Section 3, the Issuer will also indemnify the Underwriters, if any,
selling brokers, dealers and similar securities industry professionals
participating in the distribution, their officers and directors and each Person
who controls such Persons (within the meaning of the Securities Act and the
Exchange Act) to the same extent as provided above with respect to the
indemnification of the Holders, if requested in connection with any Registration
Statement.

     (b) Each Holder agrees, severally and not jointly, to indemnify and hold
harmless the Issuer, the Initial Purchasers and the other selling Holders, and
each of their respective trustees, directors, officers who sign the Registration
Statement and each Person, if any, who controls the Issuer, any Initial
Purchaser and any other selling Holder within the meaning of either Section 15
of the 1933 Act or Section 20 of the 1934 Act to the same extent as the
foregoing indemnity from the Issuer to the Initial Purchasers and the Holders,
but only with reference to information relating to such Holder furnished to the
Issuer in writing by such Holder expressly for use in any Registration Statement
(or any amendment thereto) or any Prospectus (or any amendment or supplement
thereto).

     (c) In case any proceeding (including any governmental investigation) shall
be instituted involving any person in respect of which indemnity may be sought
pursuant to either paragraph (a) or paragraph (b) above, such person (the
"INDEMNIFIED PARTY") shall promptly notify the person against whom such
indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such

                                      A-12
<PAGE>   47

proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the indemnifying party
and the indemnified party shall have mutually agreed to the retention of such
counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party
and representation of both parties by the same counsel would be inappropriate
due to actual or potential differing interests between them. It is understood
that the indemnifying party shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for (a) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Initial Purchasers and all persons, if any, who control any Initial
Purchaser within the meaning of either Section 15 of the 1933 Act or Section 20
of the 1934 Act, (b) the fees and expenses of more than one separate firm (in
addition to any local counsel) for the Issuer, its directors, its officers who
sign the Registration Statement and each person, if any, who controls the Issuer
within the meaning of either such Section and (c) the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Holders and
all persons, if any, who control any Holders within the meaning of either such
Section, and that all such fees and expenses shall be reimbursed as they are
incurred. In such case involving any Initial Purchaser and persons who control
any Initial Purchaser, such firm shall be designated in writing by the
Representatives. In such case involving the Holders and such persons who control
Holders, such firm shall be designated in writing by the Majority Holders. In
all other cases, such firm shall be designated by the Issuer. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent but, if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened proceeding in respect of which such indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

     (d) If the indemnification provided for in paragraph (a) or paragraph (b)
of this Section 4 is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities, then each indemnifying
party under such paragraph, in lieu of indemnifying such indemnified party
thereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party or parties on the one hand and of the indemnified party or parties on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Issuer and the Holders shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Issuer or by the Holders
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Holders'
respective obligations to contribute pursuant to this Section 5(d) are several
in proportion to the respective number of Registrable Notes of such Holder that
were registered pursuant to a Registration Statement.

                                      A-13
<PAGE>   48

     (e) The Issuer, the Initial Purchasers and each other Holder agree that it
would not be just or equitable if contribution pursuant to this Section 5 were
determined by pro rata allocation or by any other method of allocation that does
not take account of the equitable considerations referred to in paragraph (d)
above. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages and liabilities referred to in paragraph (d) above shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 5, no Holder shall be required to indemnify or
contribute any amount in excess of the amount by which the total price at which
Registrable Notes were sold by such Holder exceeds the amount of any damages
that such Holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The remedies provided for in this Section 5
are not exclusive and shall not limit any rights or remedies which may otherwise
be available to any indemnified party at law or in equity.

     The indemnity and contribution provisions contained in this Section 5 shall
remain operative and in full force and effect regardless of (i) any termination
of this Agreement, (ii) any investigation made by or on behalf of the Initial
Purchasers, any Holder or any person controlling the Representatives or any
Holder, or by or on behalf of the Issuer, its officers or directors or any
person controlling the Issuer, (iii) acceptance of any of the Exchange Notes and
(iv) any sale of Registrable Notes pursuant to a Shelf Registration Statement.

     6. Miscellaneous.

     (a) No Inconsistent Agreements. The Issuer has not entered into, and on or
after the date of this Agreement will not enter into, any agreement which is
inconsistent with the rights granted to the Holders of Registrable Notes in this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Issuer's other issued
and outstanding securities under any such agreements.

     (b) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless the Issuer has obtained the written consent of Holders of at least a
majority in aggregate principal amount of the outstanding Registrable Notes
affected by such amendment, modification, supplement, waiver or consent;
provided, however, that no amendment, modification, supplement, waiver or
consents to any departure from the provisions of Section 5 hereof shall be
effective as against any Holder of Registrable Notes unless consented to in
writing by such Holder.

     (c) Notices. All notices and other communications provided for or permitted
hereunder shall be made in writing by hand-delivery, registered first-class
mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if
to a Holder, at the most current address given by such Holder to the Issuer by
means of a notice given in accordance with the provisions of this Section 6(c),
which address initially is, with respect to the

                                      A-14
<PAGE>   49

Representatives, the address set forth in the Purchase Agreement; and (ii) if to
the Issuer, initially at the Issuer's address set forth in the Purchase
Agreement and thereafter at such other address, notice of which is given in
accordance with the provisions of this Section 6(c).

     All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five business
days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next business day if timely delivered to an air courier guaranteeing
overnight delivery.

     Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee, at the
address specified in the Indenture.

     (d) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Notes in
violation of the terms of the Purchase Agreement. If any transferee of any
Holder shall acquire Registrable Notes, in any manner, whether by operation of
law or otherwise, such Registrable Notes shall be held subject to all of the
terms of this Agreement, and by taking and holding such Registrable Notes such
person shall be conclusively deemed to have agreed to be bound by and to perform
all of the terms and provisions of this Agreement and such person shall be
entitled to receive the benefits hereof. The Representatives (in their capacity
as Representatives) shall have no liability or obligation to the Issuer with
respect to any failure by a Holder to comply with, or any breach by any Holder
of, any of the obligations of such Holder under this Agreement.

     (e) Third Party Beneficiary. The Holders shall be third party beneficiaries
to the agreements made hereunder between the Issuer, on the one hand, and the
Initial Purchasers, on the other hand, and shall have the right to enforce such
agreements directly to the extent it deems such enforcement necessary or
advisable to protect its rights or the rights of Holders hereunder.

     (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

     (g) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

     (h) Governing Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York.

     (i) Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

                       OPINION OF SPECIAL DELAWARE COUNSEL
                           FOR AERCO USA AND AERFI POL

1.       Each of AerCo USA and AerFi POL (the "DELAWARE ENTITIES") has been duly
         incorporated and is legally and validly existing in good standing as a
         Delaware corporation with full power and authority under its
         certificate of incorporation, by-laws and the laws of Delaware to own
         its property and to conduct its business as described in the Memoranda,
         and has full corporate power and authority to execute, deliver and
         perform its obligations under each of the Relevant Documents to which
         it is a party.

2.       All of the issued shares of each of the Delaware Entities have been
         duly and validly authorized and issued and are fully paid and
         non-assessable, and all such shares of AerCo USA are, and such shares
         of each other Delaware Entity transferred to the Issuer on the Closing
         Date will be, held by the Issuer, free and clear of all liens, charges,
         claims, pledges or other encumbrances.

3.       Each of the Relevant Documents to which any Delaware Entity is a party
         has been duly authorized, executed and delivered by such Delaware
         Entity.

4.       The execution, delivery and performance of each Relevant Document and
         compliance with the terms thereof, and the consummation of the
         transactions contemplated thereby by each of the Delaware Entities do
         not conflict with or result in a breach or violation of any of the
         terms or provisions of, or constitute a default under, or result in or
         require the creation or imposition of any lien, encumbrance, equity,
         claim or other charge upon any properties or assets of any such
         Delaware Entity or any of its subsidiaries pursuant to the terms of any
         indenture, mortgage, deed of trust, loan agreement or other agreement
         or instrument to which it is a party or by which it is bound or to
         which any of its properties or assets is subject, nor, assuming
         compliance with the rules and regulations of the FAA, will such actions
         result in any violation of, or conflict with, any statute, rule or
         regulation, or any order or decree, of any court or governmental agency
         or body of the State of Delaware having proper jurisdiction over such
         Delaware Entity or any of its properties or assets.

5.       Assuming that each Delaware Entity conducts no business in the State of
         Delaware and except for (i) such consents, approvals, filings,
         authorizations, registrations or qualifications as may be required
         under applicable state securities, "blue sky" or similar laws in
         connection with the offer, purchase and distribution of the Notes, (ii)
         such consents as have been obtained and are in full force and effect,
         (iii) such consents, approvals, filings, authorizations, registrations
         or qualifications as may be required under the rules and regulations of
         the FAA and (iv) such consents the failure of which to obtain would not
         have a material adverse effect on the financial condition, results of
         operations or business of the Issuer and its subsidiaries taken as a
         whole, no consent, approval or authorization from, or filing,
         registration or qualification with, any Delaware state court or
         governmental agency or body having jurisdiction over such Delaware
         Company or any of its subsidiaries or any of its properties or assets
         is

                                      B-1
<PAGE>   52

         required for the execution, delivery and performance of any of the
         Relevant Documents, as applicable, including the issuance,
         authentication, sale and delivery of the Notes, by such Delaware
         Company and the compliance with the terms thereof.

6.       There are no United States federal, New York or Delaware State legal or
         governmental proceedings pending or threatened to which any Delaware
         Entity or any of its subsidiaries is a party or of which any of its
         property or assets is the subject (i) asserting the invalidity of any
         Relevant Document, (ii) seeking to prevent the issuance and delivery of
         the Notes or the consummation of any of the transactions contemplated
         by any Relevant Document, (iii) seeking any determination or ruling
         that would materially and adversely affect the performance by such
         Delaware Entity or any of its subsidiaries of its obligations under any
         Relevant Document or (iv) seeking to affect adversely the United States
         federal income tax attributes of such Delaware Entity or any of its
         subsidiaries, or of any payments to be made by any party in respect of
         the Notes.

7.       Assuming each of the Relevant Documents has been duly authorized,
         executed and delivered by each of the parties thereto other than any
         Delaware Entity, each of the Relevant Documents constitutes the legal,
         valid and binding obligation of each such Delaware Entity, enforceable
         against it in accordance with its terms. Assuming the choice of law of
         another jurisdiction to govern the obligations of the parties under
         each of the Relevant Documents would be upheld as a valid choice of law
         under such law, the choice of law provision in each such Relevant
         Document would be given effect by the courts of the State of Delaware
         provided that the application of such law does not violate any
         fundamental public policy of any jurisdiction, other than the state of
         Delaware.

8.       Each of the Security Documents to which any Delaware Entity is a party
         creates a valid security interest, for the benefit of the Secured
         Parties securing payment of the Secured Obligations, in all of such
         Delaware Entity's right, title and interest in the Collateral described
         therein under the laws of the State of Delaware. The security interest
         in the Collateral is perfected under the laws of the State of Delaware.

9.       Payments by any Delaware Company under its intercompany debt to the
         Issuer will not be subject to withholding tax in the State of Delaware.

                                                                       EXHIBIT C

                           OPINION OF U.S. COUNSEL FOR
              THE AERFI COMPANIES, THE ISSUER AND THE SUBSIDIARIES

1.       The execution, delivery and performance by each of the AerFi Companies,
         the Issuer or any of the Subsidiaries of each Relevant Document to
         which it is a party, the issuance, authentication, sale and delivery by
         the Issuer of the Notes, and compliance with the terms thereof, do not
         conflict with or result in a breach or violation of any of the terms or
         provisions of, or constitute a default under, or result in or require
         the creation or imposition of any lien, encumbrance, equity, claim or
         other charge upon any properties or assets of any AerFi Company, the
         Issuer or any of the Subsidiaries pursuant to the terms of any
         indenture, mortgage, deed of trust, loan agreement or other agreement
         or instrument known to such counsel to which any of the AerFi
         Companies, the Issuer or any of its subsidiaries is a party or by which
         either of them is bound or to which any of the properties or assets of
         either of them is subject, nor, assuming compliance with the rules and
         regulations of the FAA, will such actions result in any violation of,
         or conflict with, any statute, rule or regulation, or any order or
         decree, of any court or governmental agency or body of the State of New
         York or of the United States having proper jurisdiction over either of
         such persons or any of their properties or assets.

2.       Except for (i) such consents, approvals, filings, authorizations,
         registrations or qualifications as may be required under applicable
         state securities, "blue sky" or similar laws in connection with the
         offer, purchase and distribution of the Notes, (ii) such consents as
         have been obtained and are in full force and effect, (iii) such
         consents, approvals, filings, authorizations, registrations or
         qualifications as may be required under the rules and regulations of
         the FAA and (iv) such consents the failure of which to obtain would not
         have a material adverse effect on the financial condition, results of
         operations or business of the Issuer and its subsidiaries taken as a
         whole, no consent, approval or authorization from, or filing,
         registration or qualification with, any United States federal or New
         York state court or governmental agency or body having jurisdiction
         over AerFi or the Issuer or any of their respective properties or
         assets is required for the execution, delivery and performance of any
         of the Relevant Documents, as applicable, including the issuance,
         authentication, sale and delivery of the Notes.

3.       Except as disclosed in the Memoranda, to the best of such counsel's
         knowledge after due inquiry, there are no United States federal or New
         York State legal or governmental proceedings pending or threatened to
         which AerFi or any of its subsidiaries or the Issuer or any of its
         subsidiaries is a party or of which any of their respective property or
         assets is the subject (i) asserting the invalidity of any Relevant
         Document or the Notes, (ii) seeking to prevent the issuance and
         delivery of the Notes or the consummation of any of the transactions
         contemplated by any Relevant Document, (iii) seeking any determination
         or ruling that would materially and adversely affect the performance by
         the AerFi Companies, the Issuer or the Subsidiaries of its obligations
         under any Relevant Document or the Notes or (iv)

                                      C-1
<PAGE>   54

         seeking to affect adversely the United States federal income tax
         attributes of the AerFi Companies or the Issuer or any of the
         Subsidiaries or of any payments to be made by any party under the
         Notes.

4.       The Issuer is not, and after giving effect to the offering and sale of
         the Notes and the application of the proceeds thereof as described in
         the Memoranda will not be, an investment company required to be
         registered as such under the United States Investment Company Act of
         1940, as amended.

5.       The statements in the Memoranda under the captions "Summary -- The
         Notes", "Risk Factors -- Risks Relating to AerCo and Certain Third
         Parties, -- Bankruptcy Risks, -- Certain Income Tax Risks", "The
         Acquisition of the Additional Aircraft", "Management of AerCo Group",
         "Description of the Notes" (excluding "Description of the Notes --
         AerCo's Performance Assumptions"), "Tax Considerations -- United States
         Taxation", "ERISA Considerations", "Subscription and Sale" and
         "Purchasers' Representations and Transfer Restrictions", in each case
         insofar as such statements constitute summaries of the legal matters,
         documents or proceedings referred to therein, fairly present the
         information called for with respect to such legal matters, documents or
         proceedings in all material respects.

6.       Such counsel believes that the Final Memorandum (except for financial
         and statistical data and aircraft appraisal data included therein as to
         which such counsel need not express any belief) when issued did not,
         and as of the Closing Date does not, contain any untrue statement of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading.

7.       The Notes are in the form contemplated by the Indenture and, when each
         of the Relevant Documents that is expressed to be governed by New York
         law (the "NEW YORK RELEVANT DOCUMENTS") has been duly authorized,
         issued (in the case of the Notes), executed and delivered by each of
         the parties thereto, each of the New York Relevant Documents to which
         the Issuer or any of its subsidiaries or AerFi is a party constitutes
         the legal, valid and binding obligation of each such party, enforceable
         against each such party in accordance with its terms except as (x) the
         enforceability thereof may be limited by bankruptcy, insolvency or
         other similar laws affecting creditors' rights generally and (y) rights
         of acceleration and the availability of equitable remedies may be
         limited by equitable principles of general applicability.

8.       Based upon the representations, warranties and agreements of the Issuer

         Notes under the circumstances contemplated by the Purchase Agreement
         and initial resales thereof by the Initial Purchasers in the manner

         such counsel expresses no opinion with respect to any other offer or
         resale of any of the Notes) or to qualify the Indenture in respect of
         the Notes under the Trust Indenture Act of 1939.

         security interest, for the benefit of the Secured Parties securing
         payment of the Secured

         Obligations, in all of each Grantor's right, title and interest in the
         Collateral described therein and in any proceeds thereof (within the
         meaning of Section 9.306 of the Uniform Commercial Code of the State of

         interests and of the instruments evidencing the pledged intercompany

         of the Security Documents, and assuming the continued possession by the
         Security Trustee of such certificates and instruments in the State of
         New York, the Security Documents will create, in favor of the Security
         Trustee for its benefit and the benefit of the Secured Parties to
         secure the performance of the Secured Obligations, valid and perfected
         security interest in all right, title and interest of the applicable
         Grantor in and to the pledged shares and members interests (free of any
         adverse claim), the pledged debt and the pledged investment property,
         in each case subject to no prior security interest that must be
         perfected under the UCC.

10.      The Issuer is the record owner of all of the interests pledged by it
         pursuant to the Security Documents.

11.      The Notes, when executed, authenticated and delivered by the Issuer to
         and paid for by the Initial Purchasers in accordance with the terms of
         the Indenture, will be entitled to the benefits of the Indenture.

                            OPINION OF JERSEY COUNSEL

         94-1.

(c)      The Company has an authorised share capital as set forth in the
         Offering Memorandum. All of the issued shares of the Company have been
         duly and validly authorised and issued, and are fully paid. Nineteen of
         the Company's issued shares are held by Juris Limited and Lively
         Limited, as nominees, for the benefit of the Trustee of AerCo Holding

         or to be vested in it pursuant to the Transferring Companies Share
         Purchase Agreement.

(f)      The execution, delivery, issuance and performance by the Company of
         each of the 2000 Transaction Documents (excluding the New Notes) to
         which the Company is a party and the execution, issue and delivery by
         the Company of the New Notes have been duly authorised by all necessary

         the Company is a party has been duly executed, issued and delivered by
         the Company and each of the Post Closing Documents upon execution by
         any Independent Director of the Company or any one of the authorised
         signatories named in the minutes of the meeting of directors of the
         Company held on 14th July 2000 will be duly executed by the Company.

(g)      The execution, delivery and performance by ALPS 94-1 of each of the
         2000 Transaction Documents to which ALPS 94-1 is a party have been duly
         authorised by all necessary corporate action on the part of ALPS 94-1
         and each of the 2000 Transaction Documents to which ALPS 94-1 is a
         party has been duly executed and delivered by ALPS 94-1.

(h)      The execution, delivery and performance of each of the 2000 Transaction
         Documents to which the Company or ALPS 94-1 is a party, the issuance,
         authentication, sale, delivery and performance by the Company of each
         of the New Notes, and compliance with the terms thereof, and the
         consummation by the Company and ALPS 94-1 of the transactions
         contemplated thereby do not (or, in the case of the Post Closing
         Documents, upon execution and delivery of such Post Closing Documents
         by the Company will not) conflict with or result in a breach or
         violation of any of the terms or provisions of, or constitute a default
         under, or (save for the Security Documents) result in the creation or
         imposition of any lien, charge or encumbrance upon any properties or
         assets of, the Company or ALPS 94-1, as the case may be, pursuant to
         the terms of any document expressed to be governed by Jersey law of
         which we are aware to which the Company or ALPS 94-1, as the case may
         be, is a party or by which the Company or ALPS 94-1, as the case may
         be, is bound or to which any of the properties or assets of the Company
         or ALPS 94-1, as the case may be, is subject, nor will such actions
         result in any violation of, or conflict with, the provisions of the
         memorandum and articles of association of the Company or ALPS 94-1, as
         the case may be, any generally applicable law having the force of law
         in Jersey, any Jersey statute or any Jersey order, decree, rule or
         regulation of any court or governmental agency or body in Jersey having
         proper jurisdiction over the Company or ALPS 94-1, as the case may be,
         or any of their respective properties or assets.

(i)      The obligations of the Company and ALPS 94-1 under the 2000 Transaction
         Documents to which they are respectively a party are (or, in the case
         of the Post Closing Documents, upon execution and delivery of such Post
         Closing Documents by the Company will be) legal, valid and binding and
         will be recognised and enforceable by the courts of Jersey and the
         security created or to be created by the Company under the Security
         Documents and the subordination provisions in the Security Documents
         will be binding in Jersey on creditors of the Company and any
         liquidator or person appointed to control the assets of the Company
         including the Viscount under the Bankruptcy (Desastre) (Jersey) Law
         1990 (the "1990 LAW"), and the Company.

(j)      The provisions of Article III of the Indenture (as supplemented by the
         Indenture Supplement) concerning the application of sums standing to
         the credit of the Accounts which require such sums to be applied both
         before and after service of any Default Notice, in or towards
         satisfaction of certain claims and amounts, before any such sums are
         applied in or towards certain other amounts will be recognised and
         enforceable by the courts of Jersey and binding on the parties to the
         Indenture and the Holders of the New Notes and (save as regards the
         payment of debts and other amounts which in the event of the insolvency
         of the Company are preferred by statutory or customary law but (in
         relation to the position under Jersey law only) none of which, on the
         facts known to us about the Company and save as noted at paragraph 6(r)
         below, would be of material relevance to the Company in the event of
         its insolvency) upon a liquidator and all other relevant persons,
         including the Viscount, and would not be set aside.

(k)      No consents, licences, approvals or authorisations of any governmental
         or other authority or agency in Jersey are required by law in
         connection with the execution, delivery, issue and performance of the
         2000 Transaction Documents by any of the parties thereto except for:

(i)      consent to the issue of the New Notes and the Offering Memorandum
         pursuant to the Control of Borrowing (Jersey) Order 1958 (as amended)
         (a copy of which consent is annexed); and

(ii)     consent to the circulation of the Offering Memorandum pursuant to
         Article 6(1)(d) of the Companies (General Provisions) (Jersey) Order
         1992 (a copy of which consent is annexed);

         which consents have been duly obtained and remain in effect; and

(iii)    consent to the issue of the Exchange Notes (as defined in the Class A-C
         Registration Rights Agreement) and any equivalent securities in respect
         of the Subclass D-2 Notes pursuant to the Subclass D-2 Registration
         Rights Agreement and the circulation of any prospectus contained in the
         Exchange Offer Registration Statement (as defined in the Class A-C
         Registration Rights Agreement) or in any similar document in respect of
         the Subclass D-2 Notes (as contemplated by the Subclass D-2
         Registration Rights Agreement) pursuant to the Control of Borrowing
         (Jersey) Order 1958 (as amended); and

(iv)     consent to the circulation of any prospectus contained in the Exchange
         Offer Registration Statement or the Shelf Registration Statement (each

                                      D-3
<PAGE>   59

         which consents the Jersey Financial Services Commission have confirmed,
         in principle, will be given upon formal application being made by or on
         behalf of the Company at the appropriate time.

         The consent referred to at (i) above is issued subject to certain
         conditions. Failure to comply with those conditions would enable the
         Jersey Financial Services Commission to withdraw the consent or
         otherwise claim that the Company was in breach of the Control of
         Borrowing (Jersey) Law 1947 (as amended) but such withdrawal would not
         invalidate action taken by the Company at a time when such consent was
         valid and effective. There is no annual filing requirement or
         requirement to pay fees in order to keep either consent referred to at
         (i) or (ii) above valid and effective.

(l)      No filing or registration of any of the 2000 Transaction Documents is
         necessary under Jersey law except:

(i)      the filing of a copy of the Offering Memorandum (signed by or on behalf
         of each of the Directors of the Company) pursuant to Article 6(1)(c) of
         the Companies (General Provisions) Order 1992), which filing has been
         duly effected; and

(ii)     the filing of a copy of the Indenture Supplement with the Jersey
         Companies Registry, which filing will take place as soon as practicable
         after the Closing Date.

(m)      Under current Jersey law and practice and in reliance on concessions
         written by the Comptroller of Income Tax in Jersey for the benefit of
         the Company the statements in the Offering Memorandum under the
         captions "Tax Considerations - Certain Jersey Tax Considerations" and
         "Risk Factors - Certain Income Tax Risks" in respect of the Jersey tax
         treatment of the Company and ALPS 94-1 in all material respects fairly
         present the information called for with respect to such legal matters,
         documents and proceedings and fairly summarise the matters referred to
         herein.

(n)      The statements in the Offering Memorandum under the captions
         "Transaction Overview - AerCo (the first and second paragraphs thereof
         only), "Management of AerCo Group - Directors (the first paragraph
         thereof only) and "Enforcement of Civil Liabilities" in respect of
         matters of Jersey law or relating to the constitution of the Company in
         all material respects fairly present the information called for with
         respect to such legal matters, documents and proceedings and fairly
         summarise the matters referred to therein.

(o)      The Company will qualify as an "exempt company" under the provisions of
         Article 123A of the Income Tax (Jersey) Law 1961 as amended (the "1961
         LAW") provided that:

(1)      it makes an annual application within the time limit and in the manner
         prescribed in Article 123A of the 1961 Law for exempt company status
         and pays annually the exempt company fee (currently (pound)600 (Six
         hundred pounds sterling)) on the making of such application;

                                      D-4
<PAGE>   60

(2)      no Jersey resident has a beneficial interest (as defined in Article
         123A of the 1961 Law) in the Company other than as a shareholder in or
         debenture holder of a body corporate which:-

         (i)      has a beneficial interest in the Company, and

         (ii)     is listed on a recognised stock exchange or (by concession)
                  the shares of which are traded on a recognised stock exchange;

and

(3)      it makes an annual disclosure to the Jersey Financial Services
         Commission to its satisfaction of the full name and address of the
         ultimate beneficial owners of the shares in the Company, or in the case
         of a trustee holding shares in the Company, of such details as are
         specified in the said Article 123A, and provided also that the
         Company:-

(i)      has not failed or omitted to pay income tax in respect of any previous
         years' liabilities; or

(ii)     having been for any previous year of assessment an exempt company, has
         ceased to be so.

         An exempt company may also be required to disclose to the Jersey
         Financial Services Commission the names of all persons having
         beneficial interests in the company but we have obtained the
         confirmation of the Jersey Financial Services Commission that they will
         not require the names of persons having beneficial interests in the New
         Notes.

         The expression "beneficial interest" is widely defined in the 1961 Law
         and would include holders of the New Notes. However, the Comptroller of
         Income Tax has confirmed by written concession to the Company that
         prima facie he will not so far as the Company is concerned regard a
         person having an interest (direct or indirect) in any of the New Notes
         (or in any of the notes issued by the Company in 1998) as having a
         beneficial interest in the Company for the purposes of Article 123A of
         the 1961 Law. The Comptroller of Income Tax has further confirmed that
         the holding of the issued shares of the Company by or on behalf of
         Mourant & Co. Trustees Limited (a company resident in Jersey) as
         trustee of AerCo Holding Trust, a discretionary charitable trust, (as
         to nineteen shares) and AerFi Group (as to one share) will not
         prejudice the Jersey tax status of the Company.

         So long as the Company qualifies as an exempt company in the manner
         hereinbefore described, it will be treated for the purposes of the 1961
         Law as not resident in Jersey, and will pay no Jersey income tax other
         than on income arising in Jersey (but by long standing concession
         excluding bank deposit interest arising in Jersey) and on profits of
         its trade (if any) carried on through an established place of business
         in Jersey and no withholding tax will be deducted (i) from interest,
         principal or premium paid on the New Notes; (ii) from payments made by
         the Company pursuant to the

                                      D-5
<PAGE>   61

         Transferring Companies Share Purchase Agreement or (iii) from fees paid
         by the Company pursuant to the 2000 Transaction Documents on account of
         Jersey tax. Our review of the Documents has led us to the opinion that,
         subject always to the observance by the Company of the restrictions on
         its business activities set out in Section 5.02(e) of the Indenture,
         the Company will not have any income arising in Jersey. The Comptroller
         of Income Tax has confirmed by reference to information set out in the
         Offering Memorandum that:-

(a)      the income generated and to be generated by the activities currently
         undertaken by the Company as so described therein will not be treated
         as income arising in Jersey; and

(b)      the administration in and from Jersey of the business currently
         undertaken by the Company as so described therein does not constitute
         the carrying on of a trade through an established place of business in
         Jersey for the purposes of Article 123A of the 1961 Law;

         and accordingly that whilst the Company maintains its status as an
         exempt company it will not be subject to any form of taxation in Jersey
         on its income or capital gains on the sale of any assets.

(p)      ALPS 94-1 will qualify as an "exempt company" under the provisions of
         Article 123A of the 1961 Law provided that the conditions set out in
         sub paragraphs (1), (2) and (3) of paragraph 5(o) above are met. The
         Comptroller of Income Tax has confirmed by written concession that on
         the basis that ALPS 94-1 is a wholly owned subsidiary of AerCo, and
         having regard to the Company's qualification as an exempt company as
         described in paragraph 5(o) above, for so long as the Company qualifies
         as an exempt company ALPS 94-1 will continue to be entitled to exempt
         company status under Article 123A of the 1961 Law.

         So long as ALPS 94-1 qualifies as an exempt company in the manner
         hereinbefore described, it will be treated for the purposes of the 1961
         Law in the same way as the Company (as described in paragraph 5(o)
         above).

(q)      The capital gains of the Company and ALPS 94-1 will not be subject to
         taxation in Jersey.

(r)      There is no value added tax or other taxation in Jersey relevant to the
         Company or ALPS 94-1.

(s)      No stamp duty, stamp duty reserve tax or issue, documentary,
         registration or other similar tax imposed by any government department
         or other taxing authority of or in Jersey is payable in connection with
         the creation, initial issue or delivery of the New Notes or on the
         execution and delivery of the 2000 Transaction Documents nor on any
         subsequent transfer of New Notes save that if any New Note is situate
         in Jersey on the death of the holder thereof, duty of up to 1% of the
         value of the holder's assets in Jersey is payable on the letters of
         administration or grant of probate required to enable the New Notes to
         be transferred.

(t)      The choice of the laws expressed to govern the 2000 Transaction
         Documents will be recognised and applied by the Jersey courts on proof
         of the relevant provisions of such laws.

(u)      The submission by each of the Company and ALPS 94-1 under any of the
         2000 Transaction Documents to which it is party to the jurisdiction of
         any New York State or United States Federal Court is valid, binding and
         enforceable under the laws of Jersey.

(v)      Any final and conclusive monetary judgement obtained against the
         Company or ALPS 94-1, as the case may be, in a New York court, an Irish
         court or a Swedish court in respect of any sum payable by it under the
         2000 Transaction Documents would constitute a good cause of action for
         a law suit in Jersey to enforce such judgment without re-examination of
         the issues, provided that:

(i)      the foreign court which renders such judgment has properly established
         jurisdiction over the Company or ALPS 94-1, as the case may be;

(ii)     such judgment was not obtained by fraud on the part of any party
         thereto or of the court;

(iii)    such judgement was not rendered according to principles contrary to
         public policy in Jersey;

(iv)     such judgment was not in respect of taxes, fines, penalties or other
         similar fiscal or revenue liabilities of the Company or ALPS 94-1, as
         the case may be; and

(v)      such judgment was not rendered according to principles contrary to the
         principles of natural justice.

(w)      A judgment of a superior Isle of Man court (Her Majesty's High Court of
         Justice of the Isle of Man (including the Staff of Government
         Division)) against the Company under the IOM Mortgage or the Post
         Closing IOM Mortgage will be recognised and enforced by the Jersey
         courts subject to the provisions of the Judgments (Reciprocal
         Enforcement) (Jersey) Law 1960 and subordinate legislation made
         thereunder (the "1960 LAW").

(x)      Except as set out in paragraphs 6 and 7 below and as set out at Section
         4.01(g) of the Cash Management Agreement, Section 4.01(d) of the
         Administrative Agency Agreement, Section 4.01(g) of the Standby Cash
         Management Agreement and Section 4.01(d) of the Standby Administrative
         Agency Agreement, any party to any of the 2000 Transaction Documents is
         entitled to sue as plaintiff in the Jersey courts for the enforcement
         of rights against the Company or ALPS 94-1 under any of the 2000
         Transaction Documents without any restrictions on such entitlement
         which restrictions are not generally applicable to any company
         incorporated in Jersey.

(y)      To the best of our knowledge, neither the Company nor ALPS 94-1 has
         taken any action, nor have any other steps been taken or legal
         proceedings started or threatened

                                      D-7
<PAGE>   63

         against the Company or ALPS 94-1 as a result of which it could become
         bankrupt or for its winding up, dissolution or re-organisation or for
         the appointment of a liquidator, receiver, administrator,
         administrative receiver, examiner or similar officer of it or of all or
         any of its assets or revenues.

(z)      Neither AerFi Group as holder of the Subclass E-2 Notes nor the Class E
         Note Directors (as defined in the Articles of Association of the
         Company) have any right, benefit or interest in the Company which,
         under the laws of Jersey, would constitute equity share capital within
         the meaning of that term contained in Article 1 of the Companies
         (Jersey) Law 1991, a copy of which is attached to this opinion.

2.       Our opinion is subject to the following qualifications.

(a)      The searches at the office of the Registrar of Companies referred to in
         paragraphs 5(a)(i) and 5(b)(i) are not conclusively capable of
         revealing whether or not:-

(i)      a winding up order has been made or a resolution passed for the winding
         up of the Company or ALPS 94-1 as the case may be;

(ii)     an order has been made or a resolution passed appointing a liquidator
         or other similar person to control the assets of the Company or ALPS
         94-1, as the case may be;

         as notice of these matters might not be filed with the Registrar of
         Companies immediately and, when filed, might not be entered on the
         public record of the Company or ALPS 94-1, as the case may be,
         immediately. In this connection, we refer you to the AerCo Corporate
         Certificate pursuant to which a Director of the Company has certified
         that (x) no such order has been made and no resolution has been passed
         or is proposed by the Directors of the Company in this connection; (y)
         no such order has been made and no resolution passed by the
         shareholders of the Company in this connection; and (z) he has no
         reason to believe that any such order or that any such resolution is
         proposed by the shareholders of the Company in this connection.

(b)      The enquiries at the office of the Viscount referred to in paragraphs
         5(a)(ii) and 5(b)(ii) relate only to a declaration that the Company or
         ALPS 94-1, as the case may be, is or was "en desastre" and no
         indication of applications for such declarations as yet unheard is
         given. There is no formal procedure for determining whether the Company
         or ALPS 94-1, as the case may be, has otherwise become bankrupt as
         defined in the Interpretation (Jersey) Law 1954 (as amended). In this
         connection we refer you to the AerCo Corporate Certificate pursuant to
         which a Director of the Company has certified that he has no reason to
         believe that any of the procedures referred to in that definition have
         been or are about to be invoked.

(c)      The choice of the laws expressed to govern the 2000 Transaction
         Documents would not be recognised or upheld if the choice of law was
         not bona fide and legal (although no choice of law expressed to govern
         the 2000 Transaction Documents is contrary to the laws of Jersey) or if
         there were reasons for avoiding the choice of law on the grounds of
         public policy (although none of the provisions of the 2000 Transaction

                                      D-8
<PAGE>   64

         Documents are inconsistent with Jersey public policy). The choice of
         such laws would not be upheld, for example, if it was made with the
         intention of evading the laws of the jurisdiction with which a 2000
         Transaction Document had its most substantial connection and which law
         in the absence of such choice would have invalidated the 2000
         Transaction Document or been inconsistent therewith.

(d)      Where a foreign court (being a court of any country or territory
         outside the United Kingdom other than one for whose international
         relations the United Kingdom is responsible) has given a judgment for
         multiple damages against a qualifying defendant (which would include
         the Company and ALPS 94-1) the amount which may be payable by such
         defendant may be limited by virtue of the Protection of Trading
         Interests Act 1980 (Jersey) Order 1983 (the "1983 ORDER") which
         provides that such qualifying defendant may be able to recover any such
         amount paid by it as represents the excess in such multiple damages
         over the sum assessed as compensation by the court that gave the
         judgment. The 1983 Order defines a judgment for "multiple damages" as a
         judgment for an amount arrived at by doubling, trebling or otherwise
         multiplying a sum assessed as compensation for the loss or damage
         sustained by the person in whose favour the judgment is given.

(e)      Jersey courts can give judgments in currencies other than pounds
         sterling if, subject to the terms of the contract, it is the currency
         which most fairly expresses the plaintiff's loss. However a judgment
         against the Company or ALPS 94-1 expressed in a currency other than the
         currency of Jersey (pounds sterling) which is registered by the Jersey
         Court under the 1960 Law will be so registered as if it were a judgment
         for such sum in the currency of Jersey as on the basis of the rate of
         exchange prevailing on the date of the judgment of the court of
         original jurisdiction, is equivalent to the sum so payable.

(f)      A Jersey court has power to stay an action where it is shown that there
         is some other forum, having competent jurisdiction, which is more
         appropriate for the trial of the action, that is, in which the case can
         be tried more suitably for the interests of all the parties and the
         ends of justice, and where staying the action is not inconsistent with
         the Rules of the Royal Court of Jersey.

(g)      Under the rules of procedure applicable, a Jersey court will normally
         order a plaintiff in an action, being a party who is not ordinarily
         resident in Jersey and/or does not have assets within the jurisdiction,
         to provide security for costs.

(h)      A determination, designation, calculation or certificate of any party
         to a 2000 Transaction Document, as to any matter provided for in such
         2000 Transaction Document might, in certain circumstances, be held by a
         Jersey court not to be final, conclusive or binding (for example, if it
         could be shown to have an unreasonable or arbitrary basis or not to
         have been reached in good faith) notwithstanding the provisions of that
         2000 Transaction Document.

(i)      Any provisions in any of the 2000 Transaction Documents providing for
         the payment of interest on unpaid amounts would be unenforceable in
         Jersey if such provisions were held to constitute a penalty and not a
         genuine and reasonable pre-estimate of the

                                      D-9
<PAGE>   65

         loss likely to be suffered as a result of the default in payment of the
         amount in question. We express no opinion as to whether any such
         provision does constitute such a genuine and reasonable pre-estimate.

(j)      In some circumstances a Jersey court would not give effect to a
         provision in a 2000 Transaction Document which attempts to make one or
         more provisions in that 2000 Transaction Document severable from other
         provisions therein, in particular if to do so would not accord with
         public policy or would involve the court in making a new contract for
         the parties.

(k)      A Jersey court may refuse to give effect to any provisions in an
         agreement (i) for the payment of the costs of enforcement (actual or
         contemplated) or of unsuccessful litigation brought before a Jersey
         court or where the court has itself made an order for costs or (ii)
         which would involve the enforcement of foreign revenue or penal or
         other public laws or (iii) which would be inconsistent with the
         fundamental policy of Jersey law (although none of the provisions of
         the 2000 Transaction Documents are inconsistent with such fundamental
         policy).

(l)      The term "enforceable" as used in paragraph 5 of this opinion means
         that the obligations assumed by the relevant party under the relevant
         2000 Transaction Document are of a type which the Jersey courts
         customarily enforce. This opinion is not to be taken to imply that any
         obligation would necessarily be capable of enforcement or be enforced
         in all circumstances in accordance with its terms. In particular:-

(i)      enforcement may be limited by applicable laws (in Jersey and elsewhere)
         of bankruptcy, insolvency, liquidation, re-organisation and other laws
         of general application relating to, or affecting the rights of,
         creditors although this is not intended to prejudice our opinion
         concerning (x) the enforceability of the Security Documents and the
         Indenture (as supplemented by the Indenture Supplement) at paragraphs
         5(i) and 5(j) above or (y) the enforceability of the Company's
         obligations under the Transferring Companies Share Purchase Agreement,
         subject always to the other provisos, assumptions and qualifications
         set out in this letter;

(ii)     enforcement may be limited by general principles of equity, for
         example, equitable remedies may not be available where liquidated
         damages are considered to be an adequate remedy;

(iii)    claims may become barred by prescription or may be or become subject to
         defences of set-off or counterclaim;

(iv)     where obligations are to be performed in a jurisdiction outside Jersey,
         they may not be enforceable in Jersey to the extent that performance
         would be illegal under the laws of the other jurisdiction;

(v)      if the performance of payment obligations is contrary to the exchange
         control regulations of any country in whose currency any amounts are
         payable, such obligations may not be enforceable in Jersey;

                                      D-10
<PAGE>   66

(vi)     the enforcement of the obligations of the parties to the 2000
         Transaction Documents may be limited by the provisions of Jersey law
         applicable to agreements held to have been frustrated by events
         happening after their execution;

(vii)    enforcement of obligations may be invalidated by reason of fraud;

(viii)   enforcement may be limited to the extent that matters which it has been
         expressly assumed herein will be done have not been done.

(m)      The enforceability of rights of set off as between parties to the 2000
         Transaction Documents will normally be determined by the law of such
         2000 Transaction Documents. However in the event that any party is the
         subject of a declaration of desastre under the 1990 Law, or is the
         subject of a creditors' or insolvent winding up under Chapter 4 of Part
         XXI of the Companies (Jersey) Law 1991 (the "1991 LAW"), Jersey law
         provides that where there have been mutual credits, mutual debts or
         other mutual dealings between debtor and creditor, an account shall be
         taken of what is due from one party to the other as at the date of a
         declaration of desastre in respect of the assets of one such party or
         the date of commencement of a creditors or insolvent winding up of a
         Jersey company in respect of such mutual dealings and the sum due from
         one party shall be set off against any sum due from the other party and
         the balance of the account and no more shall be claimed or paid on
         either side respectively.

(n)      A guarantor whose guarantee is governed by Jersey law or which is sued
         upon before the courts of Jersey may be entitled to claim "droit de
         discussion" that is, that the assets of the principal obligee whose
         obligations are guaranteed shall be exhausted before any claim against
         the guarantor under the guarantee may proceed, unless the "droit de
         discussion" has been waived. The "droit de discussion" has been
         effectively waived by the Company pursuant to the terms of the
         guarantee given by the Company in Article XII of the Indenture (as
         supplemented by the Indenture Supplement).

(o)      A co-guarantor or co-indemnitor whose indemnity to a third party is
         governed by Jersey law or is sued upon before the Jersey courts, may
         claim (unless waived) "droit de division" so as to require the division
         of the guarantor's or indemnitor's liabilities in just proportions
         between each of the co-guarantors or co-indemnitors and regardless of
         whether or not each of such co-guarantors or co-indemnitors are able to
         satisfy the proportion of the debt attributed to such co-guarantor or
         co-indemnitor. The "droit de division" has been effectively waived by
         the Company pursuant to the terms of the guarantee given by the Company
         in Article XII of the Indenture (as supplemented by the Indenture
         Supplement).

(p)      The following situations should be noted.

1.       A creditor may arrest movable property of his debtor in Jersey on an
         ex-parte application and, if he obtains confirmation of the arrest from
         the Jersey court, may require the sale of such property to satisfy the
         debt. Provided that the debtor is not declared "en desastre" within ten
         days of the confirmatory act of the Jersey court, that

                                      D-11
<PAGE>   67

         creditor also obtains a preference in the event of a subsequent
         desastre if he has not previously exercised the right to sell the
         assets so arrested.

2.       Control of property charged by the Company pursuant to any of the 2000
         Transaction Documents could pass out of the hands of the Company and/or
         the chargee upon the Company being declared "en desastre".

         In this situation the 1990 Law vests all the property of the debtor in
         the Viscount. The 1990 Law does make provision as regards the
         satisfaction of security interests created under the Security Interests
         (Jersey) Law 1983 (as amended) (the "1983 LAW") but by reference only
         to security interests as defined in the 1983 Law and they are so
         defined so as not to include charges created under a foreign law over
         assets situate outside Jersey.

         With regard to the particular situations referred to at clauses 1. and
         2. above in this sub-paragraph (p), whilst there is no Jersey statutory
         or judicial authority on point, it is our opinion that a creditor may
         only attach its debt to so much of its debtor's movable property as is
         not previously validly reserved to some other party, by grant of
         security in favour of such party or otherwise, and that the Viscount
         can only have vested in him so much of the property of a party declared
         "en desastre" as that party is able freely to dispose of or otherwise
         subject to the obligations of that party in respect thereof.

         Accordingly, it is our opinion that, subject always to the other
         reservations and assumptions herein set out, application of the matters
         described in clauses 1. and 2. above in this sub-paragraph (p) will not
         give (i) any creditor of the Company who arrests movable property of
         the Company rights in such property prior to the rights created (or, in
         the case of the Post Closing Documents, to be created) under the
         Security Documents or (ii) the Viscount control of property which is
         otherwise validly charged, assigned or mortgaged pursuant to the
         Security Documents in a manner that would deprive the Secured Parties
         of the benefits of their security.

(q)       (1)     A Jersey company may be wound up:-

(a)      at the end of the period of its existence stated in its Memorandum of
         Association (this is not applicable to the Company or ALPS 94-1);

(b)      voluntarily pursuant to a resolution of its shareholders;

(c)      by order of the Jersey court on the application of the company or a
         director or any member of the company if the court considers that it is
         just and equitable to so order; or

(d)      at completion by the Viscount of the desastre procedure under the 1990
         Law on the filing by the Viscount of notice pursuant to Article 36(2)
         of the 1990 Law of the date of payment of the final dividend unless
         notice has been given (under Article 38(3) of the 1990 Law) of criminal
         proceedings instituted or pending against the company.

                                      D-12
<PAGE>   68

         In addition a company may be struck off the register of Jersey
         companies after the observance of certain formalities as set out in
         Article 205 of the 1991 Law if:-

(i)      the Registrar of Companies has reason to believe that the company in
         question is not carrying on business or in operation;

(ii)     where the company is being wound up in a creditors' winding up, the
         Registrar of Companies has reason to believe that no liquidator is
         acting or that the affairs of the company are fully wound up and
         returns to be made by the liquidator have not been made for a period of
         six consecutive months;

(iii)    the Registrar of Companies has reason to believe that a company which
         is being wound up under Chapter 2 of Part XXI of the 1991 Law (which
         applies to the winding up of a company which has no liabilities or
         which is able to discharge its liabilities in full within six months
         after the commencement of the winding up) has for a period of six
         consecutive months failed to deliver to the Registrar certain
         statements required to be so delivered under the relevant provisions of
         Chapter 2 of Part XXI of the 1991 Law.

(2)      The circumstances in which someone may be appointed to take control of
         a Jersey company or the assets of such a company upon insolvency are as
         follows:-

(a)      upon the grant by the Royal Court of an application made by the company
         to place its property under the control of the Court ("de remettre ses
         biens entre les mains de la justice");

(b)      upon the company being declared "en desastre";

(c)      upon the grant by the Royal Court of an application made by the company
         to make general cession of its property for the benefit of its
         creditors;

(d)      upon the decision of the Royal Court judging the property of the
         company to be renounced; or

(e)      upon the appointment of a liquidator.

         It should be noted, however, that the occurrence of any of the above
         events would not per se have an effect upon the validity and effect of
         the Security Documents including, without limitation, the security
         granted thereunder but may result, for example, in delays in
         enforcement and the introduction of third parties (as identified)
         having locus standi with respect to the assets of the Company or ALPS
         94-1.

(3)      The following types of transactions by the Company or ALPS 94-1 may be
         set aside on the application of a liquidator (in a winding up) or of
         the Viscount (in a desastre):

(a)      a transaction with any person at an undervalue at any time in the
         period of five years ending with the date of the commencement of the
         winding up or the declaration of the Company or ALPS 94-1, as the case
         may be, "en desastre"; and

                                      D-13
<PAGE>   69

(b)      a transaction under which a preference is given at any time within the
         period of one year ending with the date of the commencement of the
         winding up or the declaration of the Company or ALPS 94-1, as the case
         may be, "en desastre"

         if at the time of any such transaction or preference the Company or
         ALPS 94-1, as the case may be, is unable to pay its debts as they fall
         due or becomes unable to pay its debts as they fall due in consequence
         of the transaction or preference save that this last proviso does not
         apply to a transaction at an undervalue which takes place less than two
         years before the date of the commencement of the winding up or the
         declaration of the Company or ALPS 94-1, as the case may be, "en
         desastre". However, in reliance on the assumptions in paragraphs 4(d),
         (m) and (p) of this opinion, we are of the opinion that none of the
         2000 Transaction Documents or the grant of any rights of security
         thereunder would be regarded as either a transaction at an undervalue
         or a preference.

         In addition both the liquidator in a winding up and the Viscount in a
         desastre have the power to disclaim onerous property. "Onerous
         property" is defined in Article 171 of the 1991 Law and Article 15 of
         the 1990 Law. The consequence of a disclaimer of onerous property would
         be to determine, from the date of disclaimer, the rights, interests and
         liabilities of the Company or ALPS 94-1, as the case may be, in or in
         respect of the property disclaimed, but would not, except so far as is
         necessary for the purpose of releasing the Company or ALPS 94-1, as the
         case may be, from liability, affect the rights or liabilities of any
         other person (which, in our opinion, would include all creditors of the
         Company or ALPS 94-1, as the case may be). Any person who claimed an
         interest in any disclaimed property (which would, in our opinion, in
         the case of the Company include the beneficiaries of the Security
         Documents pursuant to which security is, or will be, granted by the
         Company) may apply to the courts of Jersey for an order (which may be
         made on such terms as the court thinks fit) for the vesting of the
         disclaimed property in, or for its delivery to, such beneficiary or a
         trustee for such beneficiary. The power of the liquidator and the
         Viscount to disclaim onerous property has not to our knowledge been the
         subject of any Jersey judicial authority or judicial decision in the
         courts of Jersey. However, it should be noted that the relevant
         provisions of Jersey law do provide that a person sustaining loss or
         damage in consequence of the operation of a disclaimer (which could
         include creditors of the Company or ALPS 94-1) shall be deemed to be a
         creditor of the Company or ALPS 94-1, as the case may be, to the extent
         of the loss or damage and may prove for the loss or damage in a
         subsequent winding-up or desastre. Were a liquidator (or the Viscount)
         to disclaim any property of the Company on the grounds that it is
         onerous, it would be our opinion that an application to the courts of
         Jersey, of the type referred to above, by the Security Trustee (or by
         any beneficiary of the security granted by the Company to the Security
         Trustee) for the vesting of the property directly in the Security
         Trustee would succeed, on the basis that the property in question has
         been validly mortgaged or charged to the Security Trustee and the power
         of disclaimer should not be used in such a way as to defeat such a
         security.

(4)      An order of the Courts of the Republic of Ireland setting aside all or
         part of the transactions contemplated by the 2000 Transaction Documents
         consequential upon

                                      D-14
<PAGE>   70

         the insolvency of AerFi Group or otherwise would be recognised if such
         order was effective to set aside the relevant agreement or arrangement
         under the law by which the same is governed and assuming the proper
         jurisdiction of the Courts of the Republic of Ireland in connection
         therewith.

(r)      If the assets of the Company or ALPS 94-1 were to be declared "en
         desastre" in Jersey, the 1990 Law provides that the Viscount shall
         apply the assets of the Company or ALPS 94-1, as the case may be, first
         in payment of the Viscount's fees and emoluments and all costs,
         charges, allowances and expenses properly incurred by or payable by the
         Viscount in the "desastre" then in satisfaction of debts preferred by
         statutory law and customary law (as to which we refer to our opinion at
         5(j) above) and thereafter in payment of debts provable in the
         desastre. If the Company or ALPS 94-1 are wound up pursuant to Chapter
         4 of Part XXI of the 1991 Law, (a creditors' or insolvent winding up),
         a similar order of payment applies with preference for the liquidator's
         fees and costs, charges, allowances and expenses properly incurred.

(s)      The 1991 Law requires a creditor of a company (subject to appeal) to be
         bound by an arrangement entered into by the company and its creditors
         immediately before or in the course of its winding up if (inter alia)
         three quarters in number and value of the creditors acceded to the
         arrangement.

(t)      Without prejudice to the statements expressly set out in this opinion,
         we offer no opinion in relation to any representations or warranties as
         to matters of fact, opinion or view made or given (or, in the case of
         the Post Closing Documents, to be made or given) by the Company or ALPS
         94-1 in any of the 2000 Transaction Documents.

(u)      Except as specified in paragraph 5(h) hereof, we offer no opinion as to
         whether the acceptance, execution or performance of the obligations of
         the Company or ALPS 94-1 under any of the 2000 Transaction Documents
         will result in the breach of or infringe any other agreements, deeds or
         documents entered into by and binding on the Company or ALPS 94-1, as
         the case may be.

(v)      In order to maintain the good standing of the Company and ALPS 94-1
         under the laws of the Island of Jersey an annual fee must be paid and
         an annual return must be made to the Registrar of Companies in respect
         of each company before the end of February in each year. The annual
         return has been made and the annual fee paid in respect of the Company
         and ALPS 94-1 for the year 2000.

(w)      Information available in public registries in Jersey is limited and, in
         particular, there is no publicly available record of charges and
         security interests over the shares or assets of Jersey companies nor of
         applications made, or notice of any application to be made, which if
         successful would result in the Company or ALPS 94-1 becoming bankrupt
         as defined in the Interpretation (Jersey) Law 1954 (as amended).

(x)      Pursuant to the provisions of the Powers of Attorney (Jersey) Law 1995,
         as a matter of Jersey law a power of attorney (other than an
         irrevocable power of attorney given (i) for the purpose of facilitating
         the exercise of powers of a secured party under the 1983 Law, or of
         powers given pursuant to a security agreement (as defined in the

                                      D-15
<PAGE>   71

         1983 Law), or (ii) pursuant to or in connection with or for the purpose
         of or ancillary to security governed by a law other than Jersey law) is
         revoked by the death, incapacity or bankruptcy of the donor or, if the
         donor is a body corporate, by its bankruptcy or dissolution.

3.       We also make the following observations:-

(a)      We express no view on any provision in any of the 2000 Transaction
         Documents requiring written amendments and waivers of any of the
         provisions of such document in so far as it suggests that oral or other
         modifications, amendments or waivers could not be effectively agreed
         upon or granted by or between the parties or implied by the course of
         conduct of the parties.

(b)      It should be understood that we have not been responsible for
         investigating or confirming the accuracy of the facts, including
         statements of foreign law, or the reasonableness of any statements or
         opinions contained in the Offering Memorandum (other than as described
         in paragraphs 5(m) and 5(n) above) or any of the other 2000 Transaction
         Documents or that no relevant facts have been omitted therefrom.

(c)      We have not advised the Company, ALPS 94-1 or their respective
         Directors in respect of the commercial nature and effect of any of the
         transactions under the 2000 Transaction Documents or envisaged or
         undertaken pursuant thereto although we have advised the Company, ALPS
         94-1 and their respective Directors as to their duties and obligations
         as a matter of the general law of Jersey.

(d)      We have made no enquiry or assessment as to whether the Company or ALPS
         94-1 will be in a position to fulfil their respective obligations under
         the 2000 Transaction Documents to which they are respectively a party
         other than as to matters of Jersey law.

                           INDIGO IRELAND AND LORENTON

1.       Each of AerFi, AerFi Cash Management II Limited, AerFi Administrative
         Services Limited, AerCo Ireland, AerCo Ireland II, Pergola, AerFi BM,
         Ergo, Gustav I, Gustav II, Gustav III, Gustav IV, Gustav V, Gustav VI,
         Gustav VII, Gustav VIII, Gustav IX, Indigo Leasing, Indigo Ireland and
         Lorenton (the "IRISH ENTITIES") has been duly incorporated, is legally
         and validly existing as a company under the laws of Ireland with full
         power and authority under its Memorandum and Articles of Association
         and the laws of Ireland to execute, deliver and perform its obligations
         under the Relevant Documents.

2.       Each of the Relevant Documents has been duly authorized, executed and
         delivered by each of the Irish Entities party thereto.

3.       The execution, delivery and performance by each of the Irish Entities
         of each Relevant Document to which it is a party and compliance with
         the terms thereof, and the consummation by each of the Irish Entities
         of the transactions contemplated thereby do not materially conflict
         with or result in a breach or violation of any of the terms or
         provisions of, or constitute a default under, any indenture, mortgage,
         deed of trust, loan agreement, other agreement or instrument to which
         such Irish Entity is a party or by which such Irish Entity is bound or
         to which any of the properties or assets of such Irish Entity is
         subject, nor will such actions result in any material violation of, or
         conflict with, the provisions of the Memorandum and Articles of
         Association or any other constitutional documents of such Irish Entity
         or any statute, rule or regulation, or any order or decree, of any
         court or governmental agency or body of Ireland having proper
         jurisdiction over such Irish Entity or any of its properties or assets.

4.       Neither the execution or delivery by each of the Irish Entities of the
         Relevant Documents nor the performance by each such Irish Entity of any
         of the transactions contemplated thereby requires the consent or
         approval of, the giving of notice to, the registration with, or the
         taking of any other action with respect to, any governmental authority
         or agency under the laws of Ireland.

5.       All of the issued shares of each of the Irish Entities have been duly
         authorized and issued and are fully paid and not subject to calls for
         funds.

                                      E-1
<PAGE>   73

6.       The choice of law provision contained in each Relevant Document is
         valid and binding under Irish law and would be given effect by the
         courts in Ireland.

7.       The submission to jurisdiction to U.S. federal and New York State
         courts by each Irish Entity in each applicable Relevant Document to
         which it is a party and the irrevocable appointment by each such party
         of agents to receive service of process in respect of the jurisdiction
         of such courts are valid and binding under Irish law.

8.       On the basis of current Irish law and Revenue practice, no Irish stamp
         duty or other Irish documentary tax is payable in respect of any
         Relevant Document, except for duty on the Share Purchase Agreement and
         the Security Documents.

9.       True sale opinion with respect to the sale of the shares, to the extent
         Irish law is relevant, of the Transferring Companies by AerFi to the
         Issuer.

10.      Opinion to the effect that a court would not (a) make (i) a pooling
         order requiring the winding up of AerCo Group companies with AerFi or
         any of its subsidiaries, or (ii) a contribution order requiring AerCo
         Group companies to contribute towards the debts provable against any of
         AerFi and its subsidiaries in a winding up of any of AerFi and its
         subsidiaries, or (b) exercise its equitable jurisdiction to treat one
         or more companies in the AerCo Group as a single entity with one or
         more of AerFi and its subsidiaries.

11.      No member of AerCo Group would be a "related company" of any of AerFi
         or its subsidiaries and therefore for purposes of the 1990 Amendment
         Act an examiner would not be appointed to any member of AerCo Group
         solely on the ground of its being a "related company" of AerFi or its
         subsidiaries.

12.      The relevant security documents create a valid security interest in all
         of the right, title and interest in the Collateral described therein of
         the Irish Entities party thereto.

13.      The statements of Irish tax law and of our opinions in the Memoranda
         under the captions "Risk Factors -- Certain Bankruptcy Considerations",
         "The Acquisition of the Additional Aircraft -- Bankruptcy
         Considerations" and "Irish Tax Considerations" are accurate in all
         material respects.

                       OPINION OF KPMG, IRISH TAX ADVISOR
                                 TO AERCO GROUP

1.       None of the Subsidiaries [other than the Irish Entities?] will be
         subject to Irish income or corporation tax.

2.       Payments by any lessee to the Issuer or any of its Irish subsidiaries
         will not be subject to Irish VAT in any case where the Aircraft are
         used or to be used by a transport undertaking operation for reward
         chiefly on international routes.

3.       The Issuer and each of the Irish Entities will be entitled to the
         corporate tax benefits for Shannon, Ireland certified companies.

4.       The statements in the Memoranda under the captions "Risk Factors --
         Certain Income Tax Risks" and the first four paragraphs of "Tax
         Considerations -- Irish Taxation of the AerCo Group", insofar as such
         statements constitute summaries of the legal matters, documents or
         proceedings referred to therein, fairly present the information called
         for with respect to such legal matters, documents or proceedings in all
         material respects.

                         OPINION OF ISLE OF MAN COUNSEL
                           TO BALTIC II AND BALTIC III

1.       Each of Baltic II and Baltic III has been duly incorporated, is legally
         and validly existing in good standing as a company under the laws of
         the Isle of Man with full power and authority under its Memorandum and
         Articles of Association and the laws of the Isle of Man to own its
         property and to conduct its business as described in the Memoranda, and
         each of Baltic II and Baltic III has full corporate power and authority
         to execute, deliver and perform its obligations under the Relevant
         Documents to which it is a party.

2.       Each of the Relevant Documents to which Baltic II or Baltic III it is a
         party has been duly authorized, executed and delivered by Baltic II or
         Baltic III, as the case may be.

3.       The execution, delivery and performance by each of Baltic II and Baltic
         III of each Relevant Document to which it is a party and compliance
         with the terms thereof, and the consummation by each of Baltic II and
         Baltic III of the transactions contemplated thereby, do not conflict
         with or result in a breach or violation of any of the terms or
         provisions of, or constitute a default under, or result in the creation
         or imposition of any lien, encumbrance, equity, claim or other charge
         upon any properties or assets of either of Baltic II or Baltic III
         pursuant to the terms of any indenture, mortgage, deed of trust, loan
         agreement or other agreement or instrument to which Baltic II or Baltic
         III is a party or by which Baltic II or Baltic III is bound or to which
         any of the properties or assets of Baltic II or Baltic III is subject,
         nor will such actions result in any violation of, or conflict with, the
         provisions of the Memorandum and Articles of Association or any other
         constitutional documents of Baltic II or Baltic III or any statute,
         rule or regulation, or any order or decree, of any court or
         governmental agency or body of the Isle of Man having proper
         jurisdiction over Baltic II or Baltic III or any of its properties or
         assets.

4.       Neither the execution or delivery by either of Baltic II and Baltic III
         of the Relevant Documents to which it is a party, nor the performance
         by Baltic II or Baltic III of any of the transactions contemplated
         thereby, requires the consent or approval of, the giving of notice to,
         the registration with, or the taking of any other action with respect
         to, any governmental authority or agency under the laws of the Isle of
         Man.

5.       All of the member interests of Baltic II and Baltic III have been duly
         authorized and issued and are fully paid and not subject to calls for
         funds.

6.       Each of the security documents to which either of Baltic II or Baltic
         III is a party creates a valid and perfected security interest, for the
         benefit of the Secured Parties securing payment of the Secured
         Obligations, in all of each of Baltic II and Baltic III's right, title
         and interest in the Collateral of Baltic II and Baltic III described
         therein.

                          OPINION OF SWEDISH COUNSEL
                               TO AERFI SVERIGE

1.      AerFi Sverige has been duly incorporated, is legally and validly
        existing in good standing as a company under the laws of Sweden with
        full power and authority under its Memorandum and Articles of
        Association and the laws of Sweden to own its property and to conduct
        its business as described in the Memoranda, and AerFi Sverige has full
        corporate power and authority to execute, deliver and perform its
        obligations under the Relevant Documents to which it is a party.

2.      Each of the Relevant Documents to which it is a party has been duly
        authorized, executed and delivered by AerFi Sverige

3.      The execution, delivery and performance by AerFi Sverige of each
        Relevant Document to which it is a party and compliance with the terms
        thereof, and the consummation by AerFi Sverige of the transactions
        contemplated thereby do not conflict with or result in a breach or
        violation of any of the terms or provisions of, or constitute a default
        under, or result in the creation or imposition of any lien,
        encumbrance, equity, claim or other charge upon any properties or
        assets of AerFI Sverige pursuant to the terms of any indenture,
        mortgage, deed of trust, loan agreement or other agreement or
        instrument to which AerFi Sverige is a party or by which AerFi Sverige
        is bound or to which any of the properties or assets of AerFi Sverige
        is subject, nor will such actions result in any violation of, or
        conflict with, the provisions of the Memorandum and Articles of
        Association or any other constitutional documents of AerFi Sverige or
        any statute, rule or regulation, or any order or decree, of any court
        or governmental agency or body of Sweden having proper jurisdiction
        over AerFi Sverige or any of its properties or assets.

4.      Neither the execution or delivery by AerFi Sverige of the Relevant
        Documents nor the performance by AerFi Sverige of any of the
        transactions contemplated thereby requires the consent or approval of,
        the giving of notice to, the registration with, or the taking of any
        other action with respect to, any governmental authority or agency
        under the laws of Sweden.

5.      All of the issued shares of AerFi Sverige have been duly authorized and
        issued and are fully paid and not subject to calls for funds.

6.      AerFi Sverige is the owner of all of the shares of     , free and clear
        of all liens, pledges, claims, security interests or other encumbrances.

7.      Each of the pledge to which AerFi Sverige is a party creates a valid
        and perfected security interest, for the benefit of the Secured Parties
        securing payment of the Secured Obligations, in all of AerFi Sverige
        right, title and interest in the Collateral described therein.

8.       The statements in the Memoranda under the caption "The Acquisition of
         the Additional Aircraft -- Bankruptcy Considerations", insofar as such
         statements constitute summaries of legal matters, documents or
         proceedings referred to therein, in all material respects accurately
         summarize such matters.

 9.      In the event of a bankruptcy or similar proceeding under applicable
         Swedish bankruptcy law or other law governing a similar event
         (collectively, "BANKRUPTCY LAW") concerning any Swedish seller of an
         aircraft and, where appropriate, that aircraft's related lease
         (collectively, an "AIRCRAFT"), (a) a court would determine that the
         transfer of such Aircraft by the seller to a member of the AerCo Group
         under the purchase agreement therefor prior to such event would
         constitute a sale, as opposed to a secured loan, and (b) therefore, the
         Aircraft so transferred would not constitute property of such Seller's
         estate for the purposes of such Bankruptcy Law.

10.      In the event of a bankruptcy or similar proceeding under Bankruptcy Law
         concerning any Swedish seller, a court would not grant an order
         consolidating the assets and liabilities of any member of the AerCo
         Group with those of such Seller.

                  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

                  initial principal amount of $80,000,000 to refinance the Sub

                                       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:

                  (i)      failure of AerFi to make any of the payments
                           described in Clause 4 or failure of any Seller to

                           substantial part of its assets, or AerFi making an

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

         (b)      the breach of any covenant or agreement contained in this

         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

         paid in full.

         of any claim brought by the Purchaser for a breach of the Warranties or

         of such claim.

         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

         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

         endeavours to procure or to cause the Lessees of all Aircraft owned by

         coverage is terminated.

         been assigned to the relevant Company. After the date of this Agreement
         and each applicable Closing Date, the Purchasers and the Sellers

         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

13.4     FURTHER CONDITION AND AGREEMENT: The obligations of the Sellers and the
         Purchasers under this Agreement are further conditional upon no change
         having occurred after the date of this Agreement in any applicable law
         which would make it illegal for any party to this Agreement or the
         Other Transaction Documents or Related Documents to perform any of
         their respective obligations under this Agreement or such Other
         Transaction Documents or Related Documents; provided, however, that if
         any such change has occurred in relation to this Agreement, the parties
         shall co-operate and for such purposes use all reasonable endeavours to
         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
         performance of any of the obligations or other acts of the other
         parties. Any such extension shall be valid only if set forth in an
         instrument in writing signed by the party or parties to be bound
         thereby. The Sellers may waive any inaccuracies in the representations
         and warranties of the Purchasers or any condition to the Closing of the
         sale of the Shares of any of the Companies. The Purchasers may waive
         any inaccuracies in the representations and warranties of the Sellers
         made on any Closing Date or any condition to the Closing of the sale of
         the Shares of any of the Companies only with the approval in writing of
         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
         or not any Closing shall have occurred.

14.3     NOTICES: Every notice, request, demand or other communication under
         this Agreement shall:-

         (a)      be in writing delivered personally, or by prepaid courier
                  delivery services such as Federal Express, DHL or other
                  similar services, or by telex (but only where being sent to a
                  party for whom a telex number is stated in paragraph (c)
                  below) or facsimile (confirmed, in the case of facsimile, by
                  prepaid airmail letter sent within 24 hours of dispatch but so
                  that non-receipt of such confirmation shall not affect in any
                  way the validity of the facsimile in question);

         (b)      be deemed to have been received, subject as otherwise provided
                  in this Agreement, in the case of a facsimile or telex, at the
                  time of dispatch with confirmed answerback of the addressee
                  appearing at the beginning and end of the communication,
                  (provided, however, that, in the case of a facsimile, if the
                  date of dispatch is not a business day in the country of the
                  addressee it shall be deemed to have been received at the

                  letter, when delivered personally; provided, however, that if
                  personal delivery or delivery by courier of a notice is
                  tendered but refused, such notice shall be effective upon such
                  tender; and

         (c)      be sent:-

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.

             SCHEDULE 3 - REPRESENTATIONS AND WARRANTIES OF SELLERS

         PART 1 - GENERAL MATTERS AND MATTERS RELATING TO ALL OF THE COMPANIES

1.       SELLERS

         Each of the Sellers is duly incorporated or organised and validly
         existing under the laws of the jurisdiction of its incorporation or
         organisation and each has all necessary power and authority to enter
         into this Agreement and the Deed of Tax Indemnity and to carry out its
         obligations hereunder and thereunder. The execution and delivery of
         this Agreement and the Deed of Tax Indemnity by each Seller and the
         performance of its obligations hereunder and thereunder have been duly
         authorised by all requisite action on its part. This Agreement and the
         Deed of Tax Indemnity have been duly executed and delivered by the
         Sellers and (assuming due authorisation, execution and delivery by the
         Purchasers) constitute legal, valid and binding obligations of each of
         the Sellers.

2.       NO CONFLICTS

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

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

         (c)      any laws, rules, regulations, orders, judgements or decrees
                  binding on such Seller or any of the Companies; or

         (d)      in any material respect, any material agreement, instrument or
                  document which is binding upon such Seller or any of the
                  Companies or any of their respective assets nor result in the
                  creation of any Lien, other than Permitted Liens, over any of
                  their assets to be transferred to the relevant Purchaser
                  hereunder.

3.       GOVERNMENT CONSENTS AND APPROVALS

         The execution, delivery and performance of this Agreement by each
         Seller does not require any material consent, approval, authorisation
         or other order of, action by, filing with or notification to any
         Governmental Authority, other than (a) such consent, approval,
         authorisation or other order, or action by, filing with or notification
         to any Governmental Authority that will be made or obtained at or prior
         to Closing of the sale of the Shares in the relevant Company or (b) as
         described in the Disclosure Letter (as updated pursuant to Clause 12.1
         of this Agreement).

4.       FULL AND FINAL TRANSFER

         The sale of the Shares in the Irish Companies contemplated by this
         Agreement shall constitute, following registration in the registers of
         members of the Irish

                                       62
<PAGE>   63

         Companies, a full and final transfer of the legal and beneficial
         ownership of the Shares in these Companies to AerCo and/or its
         nominee(s) and after Closing of the sale and purchase of these Shares
         the relevant Sellers shall retain no right, title or interest therein.

         The sale of the Shares in each other Company pursuant to the terms and
         conditions of this Agreement shall, following registration of the
         relevant Purchaser and/or its nominee(s) in the register of members of
         that Company, constitute a full and final transfer of the legal and
         beneficial ownership of the right, title and interest of the relevant
         Sellers in those Shares to the relevant Purchaser and/or its nominee(s)
         and after Closing of the sale and purchase of those Shares the relevant
         and/or its nominees shall retain no right, title or interest therein.

5.       LITIGATION

         No litigation, arbitration or legal, governmental or administrative
         proceeding or claim which could reasonably by itself or together with
         any other such proceedings or claims:-

         (a)      have a Material Adverse Effect; or

         (b)      materially adversely affect any Seller's ability to observe or
                  perform any of its obligations hereunder or challenge the
                  legality, validity or enforceability of this Agreement or the
                  transactions contemplated hereby;

         is at present (or as of any Closing) in progress or pending or
         threatened in writing against any Seller or any of the Companies (other
         than, in the case of proceedings involving the Sellers or any of them,
         any which such Seller is contesting in good faith by appropriate
         proceedings and in respect of which proper provision has been made)
         except as set forth in the Disclosure Letter (as updated pursuant to
         Clause 12.1 of this Agreement) which describes the parties, the nature
         of the proceedings, the date and method commenced, the amount of
         damages or other relief sought and, if applicable, paid or granted.

         Orders in any material respect.

6.2      Save to the extent that same is the responsibility of the Lessee under

         maintaining all filings and has obtained and is maintaining all
         material permits, licences, registrations, qualifications,
         authorisations, certificates, exemptions, consents and approvals
         necessary to enable it to carry on its business (including in regard to
         any environmental matters) (collectively, "PERMITS") the failure to
         obtain would give rise to a fine, penalty, claim or other liability or
         sanction of or against such Company and all such Permits are in full
         force and effect.

7.       MATERIAL CONTRACTS

                  Aircraft with serial numbers 25789, 24901, 11320, 11322,

         relevant Seller(s) shall have delivered or shall have caused a copy of
         each Lease (and, where applicable, head lease) and related collateral
         document to which that Company is party (or to which that Company will
         become party on such Closing) to be delivered to or made available to

                                       64
<PAGE>   65

         (a)      Each Lease, and, where applicable, head lease, constitutes the
                  whole agreement between the parties thereto relating to the
                  applicable Aircraft other than agreements the existence of
                  which would not individually or taken together with all other
                  such agreements in respect of the Leases materially affect the
                  decision of a reasonable purchaser of the Notes to purchase
                  Notes;

         (b)      (i)      The Disclosure Letter (as updated pursuant to Clause
                           12.1 of this Agreement) contains details of any
                           current Events of Default (as such term is defined in
                           such Lease) under each Lease and, where applicable,
                           head lease involving failure by the Lessee to make
                           any payment when due under such Lease or head lease,
                           as at 30 June 2000 with respect to Aircraft owned by
                           Companies the Shares in which are transferred on the
                           Offering Closing Date, and with respect to Aircraft
                           owned by any other Company as of a date not more than
                           five Business Days prior to the applicable Closing
                           Date of the sale of the Shares in that Company;

                  (ii)     To the knowledge of such Seller(s) no other material
                           Events of Default under any Lease (or, where
                           applicable, head lease) (as such term is defined in
                           such Leases) have occurred and are continuing;

         (c)      No Event of Loss or Casualty Occurrence under any Lease (as
                  such terms are defined in such Lease) has occurred;

         (d)      To the Sellers' knowledge, there are no outstanding claims
                  which have been validly asserted by any Lessee arising out of
                  any Lease (or, where applicable, head lease), other than
                  claims constituting Permitted Liens;

         (e)      To the Sellers' knowledge, no event has occurred or act or
                  thing has been done or omitted to be done by any of the
                  Sellers or the Companies pursuant to which or as a result of
                  which any of the Leases (or, where applicable, head lease) can
                  be terminated or obligations of any such party thereunder
                  would be rendered invalid, illegal or unenforceable;

         (f)      To the Sellers' knowledge, there are no Aircraft subject to a
                  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
                  any compulsory airworthiness directives are outstanding
                  against any Aircraft;

         (g)      No claims for contributions to the cost of compliance with
                  airworthiness directives pursuant to the terms of any Lease
                  (or, where applicable, head lease) by the Sellers or the
                  Companies are outstanding against any Aircraft;

         (h)      Since the date of the Appraisers' reports, none of the
                  Aircraft has been involved in any incident which caused damage
                  in excess of the relevant Damage Notification Threshold (as
                  defined in the relevant Lease); and

                                       65
<PAGE>   66

         (i)      The rental set out in Schedule 7 (or, in the case of Aircraft
                  delivered after the Offering Closing Date) in the applicable
                  Delivery Notice is the current rental payable in respect of
                  the relevant Aircraft and there are no separate agreements or
                  understandings with respect to such Aircraft or all of the
                  Aircraft taken as a whole, which would materially affect the
                  decision of a reasonable purchaser of the Notes to purchase
                  the Notes.

9.       EMPLOYMENT

         None of the Companies has or has ever had any employees.

10.      INSURANCES

10.1     The opinion of the Insurance Adviser, with respect to the insurances
         maintained by each Company in respect of the Aircraft, Engines and
         Parts owned by it on Closing of the sale of the Shares in that Company,
         will be delivered by Closing.

10.2     All material assets, properties and risks of the Companies are, and for
         the past five years (or, if shorter, since incorporation) have been,
         covered by valid and effective insurance policies (including, without
         limitation, general liability insurance, property insurance and
         political risk insurance) issued in favour of the Companies, as the
         case may be, in each case with responsible insurance companies, in such
         types and amounts and covering such risks as are consistent with
         customary practices and standards of companies engaged in businesses
         and operations similar to those of the Companies, as the case may be.
         At the time of each Closing, and upon the completion of the
         transactions contemplated hereby, all insurance policies required above
         will be outstanding and duly in force with respect to the relevant
         Company. The Disclosure Letter (as updated pursuant to Clause 12.1 of

NOW IT IS AGREED as follows:-

1.       INTERPRETATION

         or outside

                                       84
<PAGE>   85

         Ireland) from which it appears that any Company is liable or is sought
         to be made liable to make any payment or a tax liability is likely to
         be imposed on any Company;

         "LIBOR" means the per annum offered rate for deposits in US dollars for
         a period of one month that appears on the display designated as page
         3750 on the Telerate Monitor (or such other page or service as may

         dollar deposits) at approximately 11:00 am (London time);

         "TAX ASSESSMENT" includes any assessment demand or other similar formal
         notice of a tax liability issued by or on behalf of any taxing or other
         competent authority or estimates and amounts which are due and payable
         without any formal demand or notice by or on behalf of any taxing or
         other competent authority (whether within or outside Ireland) by virtue
         of which any Company is or will with the passing of time become liable
         to make a payment of tax;

         references to any tax liability of any Company shall include not only
         liabilities of the Company to make payments of or in respect of tax but
         also:-

         (a)      the loss or setting off against income profits or gains of any
                  relief, allowance or credit in respect of any tax which would
                  (were it not for the said loss or setting off) have been
                  available to the Company and has been taken into account in
                  computing (and so reducing) any provision for deferred
                  taxation which appears (or which but for such relief allowance
                  or credit would have appeared) in the Reference Balance Sheet;

         (b)      the loss or setting off against any tax liability (for which
                  no provision has been made in preparing the Reference Balance
                  Sheet) of a right to repayment of tax which has been treated

                  Sheet; and

         (c)      the setting off against income profits or gains earned accrued
                  or received on or before Closing of any relief, allowance or
                  credit which is not available before Closing but arises in
                  respect of any event occurring after Closing in circumstances
                  where, but for such setting off, the Company would have had an
                  actual tax liability in respect of which it or the Purchasers
                  would have been able to make a claim against the Covenantor
                  under this Deed and in such a case the amount of the relief
                  allowance or credit so lost or set off (or if such relief
                  allowance or credit is a deduction from or offset against
                  gross income or profits the amount of tax which would (in the
                  case of a lost relief allowance or credit and on the basis of
                  the tax rates current at the date of such loss) have been
                  saved thereby but for such loss or in the case of a set off,
                  relief, allowance or credit the amount of tax which has been
                  saved thereby in consequence of such set off) or the amount of
                  the repayment which would otherwise have been obtained shall
                  be treated for the purposes of this Deed as a tax liability of
                  the Company;

                  of any primary or subordinate legislation or any judicial
                  decision altering the generally accepted interpretation of

         (f)      which would not have arisen but for (or if the same is
                  increased by reason of) a breach by either Purchaser of its
                  obligations hereunder; or

         (g)      which would not have arisen but for a voluntary act or

4.       CLAIMS

4.1      NOTICE BY PURCHASERS: TIME LIMIT ON CLAIMS: No claim shall be brought
         by either Purchaser in respect of any claim under this Deed unless
         notice in writing of such claim (specifying in reasonable detail (a)
         the event matter or default which gives rise to the claim and (b) the
         amount claimed) has been given to the Covenantors not later than 17
         July 2007. Upon the relevant Purchaser or any Company becoming aware of
         such a claim, the Purchaser shall or shall pursue that the Relevant
         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
         promptly by written notice request to avoid, resist, appeal or
         compromise the claim, provided that the Company shall not be obliged to
         appeal against any tax assessment raised on it if having given the
         Covenantors written notice of the receipt of such tax assessment it has
         not within 15 days thereafter received instructions in writing from the
         Covenantors in accordance with the preceding provisions of this
         sub-clause to do so.

         LATE PAYMENT TO CARRY INTEREST: If any payment due to be made by the
         Covenantors under this Deed is not made on the due date for payment
         thereof the same shall carry interest from such due date of payment
         until actual payment at the rate of 1 per cent per annum above LIBOR.

6.       PAYMENTS

6.1      TO BE MADE FREE FROM DEDUCTIONS: All sums payable by the Covenantors to

         law. If any such deductions or withholdings are required by law the
         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.

6.2      RECOVERY FROM THIRD PARTIES: If either Purchaser recovers any sum from
         a third party in respect of or relating to a tax liability which has
         been the subject of a successful claim by such Purchaser against any of
         the Covenantors or their

         claim.

         Companies may release or compromise the liability of any of the

                                [Name of Company]

I HEREBY CERTIFY that the Board of Directors of ___________________________(the

                              SOLVENCY CERTIFICATE

                                       of

                                [Name of Company]

[Name of Company] Inc (the "COMPANY") delivers this certificate in connection
with the transactions as described in the Offering Memorandum (the
"TRANSACTIONS"). Unless otherwise defined herein, terms defined in the Offering
Memorandum are used herein as therein defined.

[The Company certifies that it has carefully reviewed the Offering Memorandum
and the contents of this certificate and, in connection herewith, has made such
investigation and inquiries as it has deemed necessary and prudent therefor. The
Company further certifies that the financial information, assumptions and
valuation techniques which underlie and form the basis for the representations
made in this certificate were reasonable when made and were made in good faith
and continue to be reasonable as of the date hereof.]

The  Company  hereby  certifies  that  as of  the  date
hereof:-

1.       On the date hereof, both before and after giving effect to the
         Transactions, the fair value of the assets and the Company is greater
         than the total amount of its liabilities, including subordinated,
         absolute, fixed, matured or unmatured and liquidated or unliquidated
         liabilities, and Contingent Liabilities (as hereinafter
         defined)(collectively "LIABILITIES").

2.       On the date hereof, both before and after giving effect to the
         Transactions, the present fair saleable value of the assets of the
         Company will exceed (a) the amount that will be required to pay its
         probable liabilities on its debts as such debts become absolute and
         mature, and (b) its total Liabilities (including, without limitation,
         subordinated, unmatured, liquidated and Contingent Liabilities (as
         hereinafter defined).

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.

                                       94
<PAGE>   95

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.
