instruments are delivered to the Trustee, to each Rating Agency where it is
hereby expressly required pursuant to this Indenture and to the Issuer. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose under
this Indenture and conclusive in favor of the Trustee or the Issuer, if made in
the manner provided in this Section.

Affiliate of the Issuer shall be disregarded and deemed not to be Outstanding
for purposes of any such determination; provided that for the purposes of this

Securities of any subclass Outstanding, such Securities shall not be so
disregarded as aforesaid, and (ii) if any amount of Securities of such subclass
so owned by any such Person have been pledged in good faith, such Securities
shall not be disregarded as aforesaid if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Securities and that the pledgee is not the Issuer or any Affiliate of the
Issuer.

give any Direction in respect of such Securities. Such record date shall be the
record date specified in such Officer's Certificate which shall be a date not
more than 30 days prior to the first solicitation of Holders in connection
therewith. If such a record date is fixed, such Direction may be given before or
after such record date, but only the

                                                                              50

Holders of record of the applicable subclass at the close of business on such
record date shall be deemed to be Holders for the purposes of determining
whether Holders of the requisite proportion of Outstanding Securities of such
subclass have authorized or agreed or consented to such Direction, and for that
purpose the Outstanding Securities of such subclass shall be computed as of such
record date; provided that no such Direction by the Holders on such record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than one year after the record date.

          (e) Any Direction or other action by the Holder of any Security shall
bind the Holder of every Security issued upon the transfer thereof or in
exchange therefor or in lieu thereof, whether or not notation of such action is
made upon such Security.

of Securities, there shall at all times be maintained by the Registrar (i) an
office or agency in the location set forth in Section 13.05 hereof where
Securities of such subclass may be presented or surrendered for registration of
transfer or for exchange, (ii) an office or agency in the location set forth in
Section 13.05 (other than Ireland) for payment of Securities of any subclass
(each, a "Paying Agent") and (iii) an office or agency where notices and demands
in respect of the payment of such Securities may be served. For so long as any
Securities are listed on the Alternative Securities Market of the Irish Stock
Exchange, the Issuer shall appoint and maintain a Paying Agent in Ireland (the
"Irish Paying Agent"). Written notice of the location of each such other office
or agency and of any change of location thereof shall be given by the Trustee to
the Issuer and the Holders of such subclass. In the event that no such office or
agency shall be maintained or no such notice of location or of change of
location shall be given, presentations

                                                                              54

capital and surplus of at least $75,000,000 (or having a combined capital and
surplus in excess of $5,000,000 and the obligations of which, whether now in
existence or hereafter Incurred, are fully and unconditionally guaranteed by a
corporation organized and doing business under the laws of the United States,
any state or territory thereof or of the District of Columbia and having a

exercise corporate trust powers, subject to supervision by Federal or state
authorities (such requirements, the "Eligibility Requirements"). The Trustee
shall initially be a Paying Agent and Registrar hereunder with respect to the
Securities of each subclass.

          (c) Any corporation into which any Authorized Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authorized Agent shall
be a party, or any corporation succeeding to the corporate trust business of any
Authorized Agent, shall be the successor of such Authorized Agent hereunder, if
such successor corporation is otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the parties
hereto or such Authorized Agent or such successor corporation.

          (d) Any Authorized Agent may at any time resign by giving written
notice of resignation to the Trustee and the Issuer. The Issuer may, and at the
request of the Trustee shall, at any time terminate the agency of any Authorized
Agent by giving written notice of termination to such Authorized Agent and to
the Trustee. Upon the resignation or termination of an Authorized Agent or if at
any time any such Authorized Agent shall cease to be eligible under this Section
(when, in either case, no other Authorized Agent performing the functions of
such Authorized Agent shall have been appointed by the Trustee), the Issuer
shall promptly appoint one or more qualified successor Authorized Agents,
reasonably satisfactory to the Trustee, to perform the functions of the
Authorized Agent which has resigned or whose agency has been terminated or who

written notice of any such appointment made by it to the Trustee; and in each
case the Trustee shall mail notice of such appointment to all Holders of the
related subclass as their names and addresses appear on the Register for such
subclass.

          (e) The Issuer agrees to pay, or cause to be paid, from time to time
to each Authorized Agent reasonable compensation for its services and to
reimburse it for its reasonable expenses to be agreed to pursuant to separate
agreements with each such Authorized Agent.

     Section 2.04 Paying Agent to Hold Money in Trust. The Trustee shall require
each Paying Agent other than the Trustee to agree in writing that all moneys
deposited with any Paying Agent for the purpose of any payment on the Securities
or to the Policy Provider shall be deposited and held in trust for the benefit
of the Holders (with regard to payments on the Securities) entitled to such
payment, or the Policy Provider, as the case may be, subject to the

                                                                              55

provisions of this Section. Moneys so deposited and held in trust shall
constitute a separate trust fund for the benefit of the Holders with respect to
which such money was deposited.

          The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

     Section 2.05 Method of Payment. (a) On each Payment Date, the Trustee
shall, or shall instruct the Paying Agent (other than the Irish Paying Agent)
to, pay, to the extent of the Available Collections therefor transferred to a
Securities Account, to the Holders as of the Record Date for such Payment Date
all principal or Redemption Price of, and interest on the Securities of each
subclass (other than payments received following an Event of Default in respect
of any subclass of Securities); provided that in the event and to the extent
receipt of any payment is not confirmed by the Trustee or Paying Agent (other
than the Irish Paying Agent) by 1:00 p.m. (New York time) on such Payment Date
or any Business Day thereafter, distribution thereof shall be made on the
Business Day following the Business Day such payment is received.

          (b) Any payments on a Payment Date with respect to the Class A
Securities shall be made by wire transfer to or as instructed by the Pass
Through Trustee at least five Business Days before the applicable Payment Date
so long as it is the Holder thereof. Alternatively, upon application in writing
to the Trustee, not later than the applicable Record Date, by a Holder other
than the Pass Through Trustee of one or more Class A Securities of such subclass
having an aggregate principal amount of not less than $1,000,000, any such
payments shall be made by wire transfer to an account designated by such Holder
at a financial institution in New York, New York.

          (c) Any payments on a Payment Date with respect to the Class E
Securities shall be made by check mailed to each Holder of such Security on the
applicable Record Date at its address appearing on the applicable Register
maintained with respect to the Class E Securities. Alternately, upon application
in writing to the Trustee not later than the applicable Record Date, by a Holder
of one or more Class E Securities having an aggregate principal amount of
$1,000,000, any such payments shall be made by one transfer to an account
designated by such Holder at a financial institution in New York, New York.

          The final payment for each subclass of Securities shall be made only
upon presentation and surrender of the Securities of such subclass by the Holder
or its agent at the Corporate Trust Office or agency of the Trustee or Paying
Agent (other than the Irish Paying Agent) specified in the notice of such final
payment given by the Trustee or Paying Agent. The Trustee or Paying Agent shall
mail such notice of the final payment of such subclass to each of the Holders of
such subclass, specifying the date and amount of such final payment no later
than five Business Days prior to such final payment and such notice shall also
be published by such publication as the Alternative Securities Market of the
Irish Stock Exchange may require and in such other publication as the Irish
Paying Agent may determine to comply with its obligations hereunder.

                                                                              56

     Section 2.06 Minimum Denomination. Each subclass of Class A Securities
shall be issued in minimum denominations of $100,000 and integral multiples of
$1,000 in excess thereof. Each subclass of Class E Securities shall be issued in
minimum denominations of $500,000.

     Section 2.07 Transfer and Exchange; Cancellation. (a) The Trustee agrees
with the Issuer that the Trustee shall keep a register (herein referred to as
the "Register") in which provisions shall be made for the registration of
Securities and the registration of transfers of Securities and a record of the
dates and payments made with respect to the Securities. The Register shall be
kept at the Corporate Trust Office, and the Trustee is hereby appointed
"Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided. A Holder may transfer a Security only by written
application to the Registrar stating the name of the proposed transferee and
otherwise complying with the terms of this Indenture, including, without
limitation, the provisions of this Section 2.07. No such transfer shall be
effective until, and such transferee shall succeed to the rights of a Holder
only upon, final acceptance and registration of the transfer by the Registrar in
the Register.

          (b) Upon surrender for registration or transfer of any Security at the
Corporate Trust Office, the Issuer shall execute, upon the written request of
such Holder, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
class and of a like aggregate principal amount. At the option of a Holder, its
Securities may be exchanged for other Securities of the same class of any
authorized denomination, of a like aggregate principal amount, upon surrender of
the Securities to be exchanged at the Corporate Trust Office. Each new Class A
Security issued upon transfer or exchange shall be in a principal amount of at
least $100,000 and each new Class E Security issued upon transfer or exchange
shall be in a principal amount of at least $500,000 (and, in each case, if less,
the then unpaid principal amount thereof) and dated the date or dates to which
interest on the Security surrendered shall have been paid or, if no such
interest shall have been paid, the applicable date of issuance. Whenever any
Securities are so surrendered for exchange, the Issuer shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. All Securities issued upon any registration
of transfer or exchange of Securities shall be the valid obligations of the
Issuer evidencing the same respective obligations, and entitled to the same
security and benefits under this Indenture, as the Securities surrendered upon
such registration of transfer or exchange. When Securities are presented to the
Registrar with a request to register their transfer or to exchange them for an
equal principal amount of Securities of other authorized denominations, the
Registrar shall register the transfer or make the exchange as requested if the
requirements for such transactions are met (including, in the case of a
transfer, that such Securities are duly endorsed or accompanied by a written
instrument of transfer in form satisfactory to the Trustee and Registrar duly
executed by the Holder thereof or by an attorney who is authorized in writing to
act on behalf of the Holder). In addition, the Trustee may require evidence
satisfactory to it as to the compliance of any such transfer with the Securities
Act of 1933, as amended. The Trustee shall make a notation on each new Security
or Securities of the amount of all payments of principal previously made on the
old Security or Securities with respect to which such new Security is issued and
the date to which interest accrued on such old Security or Securities has been
paid.

                                                                              57

          (c) Prior to the due presentment for registration of transfer of a
Security, the Issuer and the Trustee may deem and treat the applicable
registered Holder as the absolute owner and Holder of such Security for the
purpose of receiving payment of all amounts payable with respect to such
Security and for all other purposes and shall not be affected by any notice to
the contrary.

          (d) The Issuer shall not be required to exchange any surrendered
Securities as above provided during the 15 calendar day period preceding the due
date of any payment on such Securities. The Issuer shall not be required to
exchange or register the transfer of any Securities as above provided during the
15 calendar days preceding the Final Maturity Date of any such Securities or
during the 15 calendar days preceding the first mailing of any notice of
Redemption or Refinancing of Securities to be redeemed or refinanced. The Issuer
shall not be required to exchange or register the transfer of any Securities
that have been selected, called or are being called for Redemption or
Refinancing except, in the case of any Securities where notice has been given
that such Securities are to be redeemed in part, the portion thereof not so to
be redeemed.

          (e) A Security may not be exchanged for another Security other than as
provided in this Section 2.07 and Section 2.08 hereof.

          (f) The Issuer at any time may deliver Securities to the Trustee for
cancellation. The Trustee and no one else shall cancel and destroy in accordance
with its customary practices in effect from time to time (subject to the record
retention requirements of the Exchange Act) any such Securities, together with
any other Securities surrendered to it for registration of transfer, exchange or
payment.

     Section 2.08 Mutilated, Destroyed, Lost or Stolen Securities. If any
Security shall become mutilated, destroyed, lost or stolen, the Issuer shall,
upon the written request of the Holder thereof and presentation of the Security
or satisfactory evidence of destruction, loss or theft thereof to the Trustee or
Registrar (including, in the case of Securities listed on the Alternative
Securities Market of the Irish Stock Exchange, at the offices of the
co-registrar in Ireland, if any), issue, and the Trustee shall authenticate and
deliver in exchange therefor or in replacement thereof, a new Security of the
same subclass, payable to such Holder in the same principal amount, of the same
maturity, with the same payment schedule, bearing the same interest rate and
dated the date of its authentication. If the Security being replaced has become
mutilated, such Security shall be surrendered to the Trustee or a Registrar and
forwarded to the Issuer by the Trustee or such Registrar. If the Security being
replaced has been destroyed, lost or stolen, the Holder thereof shall furnish to
the Issuer, the Trustee or a Registrar (i) such security or indemnity as may be
required by them to save the Issuer, the Trustee and such Registrar harmless and
(ii) evidence satisfactory to the Issuer, the Trustee and such Registrar of the
destruction, loss or theft of such Security and of the ownership thereof. The
Holders will be required to pay any tax or other governmental charge imposed in
connection with such exchange or replacement and any other expenses (including
the fees and expenses of the Trustee and any Registrar) connected therewith.

     Section 2.09 Payments of Transfer Taxes. Upon the transfer of any Security
or Securities pursuant to Section 2.07 hereof, the Issuer or the Trustee may
require from the party requesting such new Security or Securities payment of a
sum to reimburse the Issuer or the

                                                                              58

Trustee for, or to provide funds for the payment of, any transfer Tax or similar
governmental charge payable in connection therewith.

     Section 2.10 Refinancing of Securities. (a) Subject to Section 2.01(a)
hereof, paragraphs (b) and (c) below and Section 5.02(f)(ii) hereof, the Issuer
may issue Refinancing Securities pursuant to this Indenture for the purpose of
refinancing the Outstanding Principal Balance of any subclass of Securities
(including refinancings of Refinancing Securities). Each refinancing of any
subclass of Securities with the proceeds of an offering of Refinancing
Securities (a "Refinancing") shall be authorized pursuant to one or more Board
Resolutions and shall be effected only following receipt of a Rating Agency
Confirmation and upon obtaining the prior written consent of the Policy Provider
(unless a Policy Non-Consent Event has occurred or will occur in connection with
such Refinancing) and the Initial Credit Facility Provider (unless an Initial
Credit Facility Non-Consent Event has occurred or will occur in connection with
such Refinancing). Each Refinancing Security shall constitute a "Security" for
all purposes under this Indenture, and shall have the class or subclass
designation and such further designations added or incorporated in such title as
specified in the related Board Resolutions, in any indenture supplemental hereto
providing for the issuance of such Securities or specified in the form of such
Securities, as the case may be.

          (b) A Refinancing of any subclass of Securities in whole or in part
may occur on any Payment Date after the Initial Closing Date and shall be
effected as an Optional Redemption pursuant to Section 3.10 hereof. On the date
of any Refinancing, the Issuer shall issue and sell an aggregate principal
amount of Refinancing Securities not to exceed the Redemption Price of the
Securities being refinanced thereby and any accrued and unpaid interest plus the
Refinancing Expenses relating thereto, any Policy Premium and Policy Redemption
Premium due and payable to the Policy Provider and any amount to be deposited in
any Cash Collateral Account for such Refinancing Securities. The proceeds of
each sale of Refinancing Securities shall be used to make the deposit required
by Section 3.10(d) hereof, to pay such Refinancing Expenses, such Policy Premium
and Policy Redemption Premium and to fund such Cash Collateral Account.

          (c) Each Refinancing Security shall contain such terms as may be
established in or pursuant to the related Board Resolution (subject to Section
2.01 hereof), in any indenture supplemental hereto providing for the issuance of
such Securities or specified in the form of such Securities to the extent
permitted below, and shall have the same ranking pursuant to Section 3.08 hereof
with respect to all other Obligations as the Securities of the class to which
such Refinancing Securities belong (and, with respect to other subclasses of
such class, as provided in Section 3.09 hereof). No less than seven Business
Days, prior to any Refinancing, any or all of the following, as applicable, with
respect to the related issue of each subclass of Refinancing Securities shall
have been determined by the Issuer and set forth in such Board Resolutions, in
any indenture supplemental hereto or specified in the form of such Securities,
as the case may be:

          (i) the Securities to be refinanced by such Refinancing Securities;

          (ii) the aggregate principal amount of such Refinancing Securities
     that may be issued;

                                                                              59

          (iii) the proposed date of such Refinancing;

          (iv) the Expected Final Payment Date and the Final Maturity Date of
     such Refinancing Securities;

          (v) whether such Refinancing Securities are to have the benefit of any
     Eligible Credit Facility and, if so, the amount and other terms thereof
     and/or any increase in the Required Amount for any Cash Collateral Account;

          (vi) the rate at which such Refinancing Securities shall bear interest
     or the method by which such rate shall be determined;

          (vii) if other than denominations of $100,000 or higher integral
     multiples of $1,000 (with respect to Class A Securities), or $500,000 (with
     respect to Class E Securities), the denomination or denominations in which
     such Refinancing Securities shall be issuable;

          (viii) whether such Refinancing Securities are to be issuable
     initially in registered or global form and, if global, whether holders of
     any such global Refinancing Security may exchange such Securities for
     Refinancing Securities of the same class or subclass and of like tenor of
     any authorized form and denomination and the circumstances under which any
     such exchanges may occur, if other than in the manner provided in Section
     2.07 hereof, and the circumstances under which and the place or places
     where any such exchanges may be made;

          (ix) any adjustments to be made, consistent with Sections 3.09 and
     3.11 hereof, to the applicable Note Pool Factors or Extended Note Pool
     Factors as a result of the issuance of such Refinancing Securities;

          (x) the class and subclass of Securities to which such Refinancing
     Securities belong;

          (xi) whether such Refinancing Securities are to be Covered Class A
     Securities; and

          (xii) any other terms, conditions, rights and preferences (or
     limitations on such rights and preferences) relating to such Refinancing
     Securities (which terms shall comply with Applicable Law and not be
     inconsistent with the requirements or restrictions of this Indenture,
     including Section 5.02(f)(ii) hereof).

          If any of the terms of any issue of Refinancing Securities are
established by action taken pursuant to one or more Board Resolutions, such
Board Resolutions shall be delivered to the Trustee setting forth the terms of
such Refinancing Securities.

          (d) In connection with any Refinancing of the Subclass A-1 Securities
or any other subclass of Covered Class A Securities that has occurred with the
prior written consent of the Policy Provider, each of the Policy and the Policy
Provider Agreement shall be amended to cover the corresponding class of
Certificates relating to such subclass of Covered Class A Securities and the
Policy Provider shall deliver a new Policy or amended Policy, as applicable, to
the Drawing Agent; provided that if the Refinancing Securities of such
Refinancing will not be

                                                                              60

Covered Class A Securities, no amendment of the Policy and the Policy Provider
Agreement shall be required and no delivery of an amended Policy or new Policy
shall be required; provided further that, notwithstanding anything to the
contrary herein, Class A Securities that are not Covered Class A Securities may
not be issued while the Policy remains outstanding. In connection with the
amendment of the Policy to cover the Certificates relating to the Refinancing
Securities, the Policy Provider agrees to deliver to the Issuer, the Guarantor
and Drawing Agent, on or prior to the date of Refinancing, legal opinions and
corporate documents in respect of the amended Policy, substantially similar in
form, scope and substance to the legal opinions and corporate documents
delivered by the Policy Provider on the Initial Closing Date. The Policy
Provider agrees that its rights of reimbursement in respect of the Policy
Drawings under the amended Policy will be the same as its rights of
reimbursement set forth in Section 3.08 and premium payable in respect of the
amended Policy shall be on the same basis and terms as the Policy Premium and
the Policy Redemption Premium paid in respect of the Policy issued on the
Initial Closing Date (unless otherwise agreed to by the Issuer, the Guarantor
and the Drawing Agent and the Policy Provider).

          (e) In connection with any Refinancing of a subclass of Class A
Securities that has occurred with the prior written consent of the Initial
Credit Facility Provider, the Initial Credit Facility if so required by the
terms of such Refinancing shall be amended to cover such subclass of Class A
Securities and the Initial Credit Facility Provider shall deliver a new Eligible
Credit Facility or amended Initial Credit Facility, as applicable, to the
Trustee. In connection with the amendment of the Initial Credit Facility to
cover the Refinancing Securities, the Initial Credit Facility Provider agrees to
deliver to the Issuer and the Guarantor, on or prior to the date of Refinancing,
legal opinions and corporate documents in respect of the amended Initial Credit
Facility, substantially similar in form, scope and substance to the legal
opinions and corporate documents delivered by the Initial Credit Facility
Provider on the Initial Closing Date. The Initial Credit Facility Provider
agrees that its rights of reimbursement in respect of the drawings under the
amended Initial Credit Facility will be the same as its rights of reimbursement
set forth in Section 3.08, and fees payable in respect of the amended Initial
Credit Facility shall be on the same basis and terms as the fees paid in respect
of the Initial Credit Facility entered into on the Initial Closing Date.

          (f) In connection with any Refinancing, the Issuer shall pay to all
parties to the Related Documents all reasonable costs and expenses related
thereto.

          (g) Notwithstanding anything to the contrary herein, if the Class A
Securities are refinanced with Class A Securities that are not covered by the
Policy, the issuance of such new uninsured Class A Securities shall be subject
to the following conditions precedent:

          (i) the payment in full of all outstanding Policy Provider Obligations
to the Policy Provider; and

          (ii) the return of the Policy to the Policy Provider for cancellation
and termination.

a certificate executed by a Director stating (i) that a Remaining Aircraft has
been delivered under and in accordance with the Purchase Agreement, (ii) that no
waiver of the conditions specified in

                                                                              61

that an additional Subclass E-1 Security shall be issued to the relevant Seller
in the principal amount of the Subclass E-1 Securities allocable to such

of cash payable from the Aircraft Purchase Account allocable to such Remaining
Aircraft, as set forth in column V of Exhibit A to the Purchase Agreement, net
of the amounts provided for in the Purchase Agreement (any such amount, a

in a principal amount equal to the amount certified by the Issuer with respect
to such Remaining Aircraft to, and register such Security in the name of, the

          (b) Each Additional Security shall contain such terms as may be
established in or pursuant to the related Board Resolutions (subject to Section
2.01 hereof), in any indenture supplemental hereto providing for the issuance of
such Securities or specified in the form of such Securities to the extent
permitted below, and shall have the same ranking pursuant to Section 3.08 hereof
with respect to all other Obligations as the Securities of the class to which
such Additional Securities belong (and, with respect to other subclasses of such
class, as provided in Section 3.09 hereof). No less than seven Business Days

Securities which may be issued;

               (B) the proposed date of such Additional Issuance;

               (C) the Expected Final Payment Date and the Final Maturity Date
of any such Additional Securities;

               (D) whether any such Additional Securities are to have the
benefit of any Eligible Credit Facility and/or any increase in the Required
Amount for any Cash Collateral Account for the related class or classes of
Securities and, if so, the amount and terms thereof;

               (E) the rate at which any such Additional Securities shall bear
interest or the method by which such rate shall be determined;

               (F) if other than denominations of $100,000 or higher integral
multiples of $1,000 (with respect to Class A Securities) or $500,000 (with
respect to Class E Securities), the denomination or denominations in which any
such Additional Securities shall be issuable;

               (G) any adjustments to be made, consistent with Sections 3.09 and
3.11 hereof, to the applicable Note Pool Factors or Extended Note Pool Factors

be used to acquire Additional Aircraft or to make Conversion Payments, or both,
and:

               (A) in the case of Additional Aircraft, a description of such
Additional Aircraft and the Expected Useful Life of such Additional Aircraft;

Board Resolutions shall be delivered to the Trustee setting forth the terms of
such Additional Securities.

          (c) In the event Additional Securities are issued as Class A
Securities with the prior consent of the Policy Provider, each of the Policy and
the Policy Provider Agreement shall be amended to cover the corresponding class
of Certificates of such Additional Securities and the Policy Provider shall
deliver a new Policy or amended Policy, as applicable, to the Drawing Agent;
provided that if the Additional Securities of such Additional Issuance will not
be Covered

                                                                              63

Class A Securities, no amendment of the Policy and the Policy Provider Agreement
shall be required and no delivery of an amended Policy or new Policy shall be
required; provided further, that, notwithstanding anything to the contrary
herein, no Class A Securities may be issued without the prior written consent of
the Policy Provider (unless a Policy Non-Consent Event has occurred or will
occur in connection with such Additional Issuance) and the prior written consent
of the Initial Credit Facility Provider (unless an Initial Credit Facility
Non-Consent Event has occurred or will occur in connection with such Additional
Issuance); provided further, that, notwithstanding anything to the contrary
herein, Class A Securities that are not Covered Class A Securities may not be
issued while the Policy remains outstanding. In connection with any issuance of
Additional Securities as a subclass of Class A Securities and amendment of the
Policy, the Policy Provider agrees to deliver to the Issuer, the Guarantor and
the Drawing Agent, on or prior to the date of issuance, legal opinions and
corporate documents in respect of the amended Policy, substantially similar in
form, scope and substance to the legal opinions and corporate documents
delivered by the Policy Provider on the Initial Closing Date. The Policy
Provider agrees that its rights of reimbursement in respect of any Policy
Drawings under the amended Policy will be the same as its rights of
reimbursement set forth in Section 3.08, and premium payable in respect of the
amended Policy shall be on the same basis and terms as the Policy Premium and
Policy Redemption Premium (if any) paid in respect of the Policy issued on the
Initial Closing Date (unless otherwise agreed to by the Issuer, Guarantor and
Drawing Agent and the Policy Provider).

          (d) In connection with any issuance of Additional Securities, the
Issuer shall pay to all parties to the Related Documents all reasonable costs
and expenses related thereto.

     Section 2.13 Special Transfer Provisions.

          (a) Private Placement Legend. Upon the transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the Trustee
shall deliver Securities that do not bear the Private Placement Legend, as
applicable. Upon the transfer, exchange or replacement of Securities bearing the
Private Placement Legend, the Trustee shall deliver only Securities that bear
the Private Placement Legend, as applicable, unless there is delivered to the
Trustee an Opinion of Counsel reasonably satisfactory to the Issuer and the
Trustee to the effect that neither such legend nor the related restrictions on
transfer are required in order to maintain compliance with the provisions of the
Securities Act.

          (b) General. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such Security acknowledges the restrictions on
transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it will transfer such Security only as provided
in this Indenture. The Registrar shall not register a transfer of any Security
unless such transfer complies with the restrictions on transfer of such Security
set forth in this Indenture. In connection with any transfer of Securities, each
Holder agrees by its acceptance of such Securities to furnish the Trustee the
certifications and legal opinions described herein to confirm that such transfer
is being made pursuant to an exemption from, or a transaction not subject to,
the registration requirements of the Securities Act; provided that the Trustee
shall not be required to determine (but may rely on a determination made by the
Issuer with respect to) the sufficiency of any such legal opinions.

                                                                              64

          (c) Transfers of Class E Securities. The Class E Securities may not be
transferred unless (a) the transferee is Aircastle Limited or any of its direct
or indirect wholly-owned Subsidiaries or (b) the Trustee and the Issuer shall
have received an Opinion of Counsel from counsel or tax advisors in Ireland to
the effect that no ACS Ireland Group Member should suffer materially increased
Irish taxes as a result of the transfer.

          The Initial Securities shall be issued pursuant to an exemption from
registration under the Securities Act.

          The Trustee shall retain copies of all letters, notices and other
written communications received pursuant to this Section 2.13 in accordance with
applicable law. The Issuer shall have the right to inspect and make copies of
all such letters, notices or other written communications at any reasonable time
upon the giving of reasonable Written Notice to the Trustee during the term of
this Agreement and for a period of three months thereafter.

     Section 2.14 Temporary Securities. Pending the preparation of Securities of
any subclass, the Issuer may execute and the Trustee may authenticate and
deliver temporary Securities of such subclass which are printed, lithographed,
typewritten or otherwise produced, in any denomination, containing substantially
the same terms and provisions as are set forth in the applicable exhibit hereto
or in any indenture supplemental hereto, except for such appropriate insertions,
omissions, substitutions and other variations relating to their temporary nature
as the Director executing such temporary Securities may determine, as evidenced
by his or her execution of such temporary Securities.

          If temporary Securities of any subclass are issued, the Issuer will
cause Securities of such subclass to be prepared without unreasonable delay.
After the preparation of Securities of such subclass, the temporary Securities
shall be exchangeable for Securities upon surrender of such temporary Securities
at the Corporate Trust Office of the Trustee, without charge to the Holder
thereof. Upon surrender for cancellation of any one or more temporary
Securities, the Issuer shall execute and the Trustee shall authenticate and
deliver in exchange therefor Securities of like subclass, in authorized
denominations and in the same aggregate principal amounts. Until so exchanged,
such temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as Securities.

     Section 2.15 Statements to Holders. (a) On the second Business Day before
each Payment Date, the Issuers shall cause the Administrative Agent to deliver
to the Pass Through Trustee, the Trustees, the Cash Manager, the Directors and
the Policy Provider, and the Trustee shall (or shall instruct any Paying Agent
to) promptly thereafter distribute or make available to each Holder of record
with respect to such Payment Date, the Policy Provider, the Initial Credit
Facility Provider and each Rating Agency, a report, substantially in the form
attached as Exhibit E hereto prepared by the Administrative Agent and setting
forth the information described therein after giving effect to such payment
(each, a "Monthly Report") in respect of the Calculation Date immediately
preceding such Payment Date and the month then ended. Each Monthly Report
provided to the Pass Through Trustee, the Trustees, Directors, the Policy
Provider, the Initial Credit Facility Provider and each Rating Agency for each
May, August and November shall be accompanied by (i) a statement setting forth
an analysis of the Collections Account activity for the preceding quarter ended
on the Calculation Date occurring in the

                                                                              65

immediately preceding March, June and September, respectively, (ii) a discussion
and analysis of such activity and of any significant developments affecting the
ACS Group in such quarter and (iii) an updated description of the ACS Group
Aircraft in the ACS Group Portfolio and the related Lessees as of the end of
such quarter (each, a "Quarterly Report"). Each Monthly Report provided to the
Pass Through Trustee, the Trustees, Directors, the Policy Provider, the Initial
Credit Facility Provider and each Rating Agency for each April shall be
accompanied by (x) a statement setting forth an analysis of the Collections
Account activity for the year ended on the Calculation Date occurring in the
immediately preceding January, (y) a discussion and analysis of such activity
and of any significant developments affecting the ACS Group in such year and (z)
updated information with respect to the ACS Group Aircraft in the ACS Group
Portfolio as of the end of such year (each, an "Annual Report"). Each Quarterly
Report and Annual Report, as the case may be, shall contain a listing of the ACS
Group Aircraft that are not subject to any ACS Group Lease. The Trustees shall
deliver a copy of, or make available via a website, each Quarterly Report and
Annual Report to any Holder or other Secured Party who requests a copy thereof.

          (b) After the end of each calendar year but not later than the latest
date permitted by law, the Issuer shall cause the Administrative Agent to
deliver to the Trustee, the Cash Manager, the Policy Provider, the Initial
Credit Facility Provider and the Directors, and the Trustee shall (or shall
instruct any Paying Agent to) furnish to each Person who at any time during such
calendar year was a Holder of record of any subclass of Securities a statement
prepared by the Administrative Agent containing the sum of the amounts
determined pursuant to Exhibit E hereto with respect to the subclass of
Securities for such calendar year or, in the event such Person was a Holder of
record of any subclass during only a portion of such calendar year, for the
applicable portion of such calendar year, and such other items as are readily
available to the Administrative Agent and which a Holder shall reasonably
request as necessary for the purpose of such Holder's preparation of its U.S.
federal income or other tax returns. In the event that any such information has
been provided by any Paying Agent directly to such Person through other
tax-related reports or otherwise, the Trustee in its capacity as Paying Agent
shall not be obligated to comply with such request for information.

          (c) The Issuer shall cause a copy of each report described in Section
2.15(a) above to be concurrently delivered by the Administrative Agent to the
Listing Agent, on behalf of the Alternative Securities Market of the Irish Stock
Exchange, each Rating Agency and the Irish Remarketing Servicer.

          (d) The Trustee shall forward the information furnished pursuant to
Section 2.15 to each Holder of record of each Security of such subclass for the
relevant period of ownership of such Security as appears on the records of the
Registrar.

          (e) Prior to a Refinancing or Redemption, the Trustee shall cause
notice thereof to be given by publication by the Irish Paying Agent in the Irish
Times or, if such newspaper shall cease to be published or timely publication
therein shall not be practicable, in such English language newspaper or
newspapers as the Trustee shall approve having a general circulation in Europe
or by way of announcement by the Irish Listing Agent at the Companies
Announcement office at the Irish Stock Exchange and by either of (A) the
information contained in such notice appearing on the relevant page of the
Reuters Screen or such other medium for the electronic

                                                                              66

display of data as may be approved by the Trustee and notified to Holders or (B)
publication in the Financial Times (European Edition) and The Wall Street
Journal (National Edition) or, if either newspaper shall cease to be published
or timely publication therein shall not be practicable, in such English language
newspaper or newspapers as the Trustee shall approve having a general
circulation in Europe and the United States, with no further publication
requirement.

          (f) Notices referred to in this Section 2.15 to Holders of the Class E
Securities generally will only be made by the Trustee directly to the registered
holders thereof by any of the methods referred to in Section 13.05 hereof.

          (g) The Trustee shall be at liberty to sanction some other method of
giving notice to the Holders of any subclass if, in its opinion, such other
method is reasonable, having regard to the number and identity of the Holders of
such subclass and/or to market practice then prevailing, is in the best
interests of the Holders of such subclass and will comply with the rules of the
Alternative Securities Market of the Irish Stock Exchange as confirmed by the
Listing Agent or such other stock exchange (if any) on which the Securities of
such subclass are then listed, and any such notice shall be deemed to have been
given on such date as the Trustee may approve; provided that notice of such
method is given to the Holders of such subclass in such manner as the Trustee
shall require with no further publication requirement.

          (h) Notwithstanding the above, any notice specifying the rate, amount
or Payment Date in respect of the Securities of any subclass bearing interest at
a floating rate or in respect of any repayment of principal on any Securities
shall, for so long as such Securities (for the avoidance of doubt, not including
the Class E Securities) are listed on the Alternative Securities Market of the
Irish Stock Exchange and so long as the rules of the Alternative Securities
Market of the Irish Stock Exchange so require, be given to the Listing Agent by
the Irish Paying Agent; provided that any notice specifying redemption of
principal of any Securities must be published in the Irish Times or another
daily newspaper of general circulation in Ireland or by way of announcement by
the Irish Listing Agent at the Companies Announcement office at the Irish Stock
Exchange. Any such notice or announcement, as the case may be, shall be deemed
to have been given on the first day on which any of such conditions shall have
been met.

     Section 2.16 CUSIP, CINS and ISIN Numbers. The Issuer in issuing the
Securities may use "CUSIP", "CINS", "ISIN" or other identification numbers (if
then generally in use), and if so, the Trustee shall use CUSIP numbers, CINS
numbers, ISIN numbers or other identification numbers, as the case may be, in
notices of redemption or exchange as a convenience to Holders; provided that any
such notice shall state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any notice
of redemption or exchange and that reliance may be placed only on the other
identification numbers printed on the Securities; provided further that failure
to use "CUSIP", "CINS", "ISIN" or other identification numbers in any notice of
redemption or exchange shall not affect the validity or sufficiency of such
notice.

     Section 2.17 Holder Representations and Covenants. Each Holder and
beneficial owner of a Security (other than a Class E Security), by the purchase
of such Security or beneficial interest therein, covenants and agrees that it
will treat such Security as indebtedness for all

                                                                              67

purposes and will not take any action contrary to such characterization,
including, without limitation, filing any tax returns or financial statements
inconsistent therewith.

     Section 2.18 European Union Insolvency Regulation. Each of the parties
hereto (other than the Issuer), and each Holder and beneficial owner of a
Security by the purchase of such Security or beneficial interest therein, hereby
acknowledges and agrees that, for the purposes of European Union Council
Regulation (EC) No. 1346/2000 on insolvency proceedings (the "Regulation") the
"centre of main interests" (as that term is defined in the Regulation) of the
Issuer is Ireland and that it has entered into this Indenture in reliance upon
the centre of main interests of the Issuer being and continuing to be in
Ireland.

delivered to the Trustee and the Guarantor Trustee, the Security Trustee and the
Cash Manager, in each case at such time as is set forth in this Section 3.01 or
in such Board Resolution or such Guarantor Board Resolution. The Issuer shall
establish a rental account (the "Irish Rental Account") and an Irish collections

purposes of this Indenture. A Certificate Account for the benefit of the holders
of the Certificates shall be established and maintained in accordance with the
terms of the Pass Through Trust Agreement.

          (b) Withdrawals and Transfers Generally. Any provision of this
Indenture relating to any deposit to, withdrawal from, or any transfer to or
from, any Account by the Cash Manager shall mean any such deposit, withdrawal or
transfer effected by the Operating Bank at the Written Notice of the Cash
Manager (such direction to be provided to the Operating Bank by 1:00 p.m. (New
York City time) on the date of such deposit, transfer or withdrawal) given in
accordance with the terms of this Indenture, the Cash Management Agreement and
the Security Trust Agreement. Each such Written Notice to the Operating Bank
shall be also communicated in computer file format or in such other form as the
Cash Manager, the Operating Bank, the Trustees and the Security Trustee agree,
provided that, in the case of communication in computer file format or any other
form other than a written tangible form, a written tangible form thereof shall
promptly thereafter be sent to the Operating Bank. No deposit to, withdrawal
from or transfer from or to any Account shall be made except in accordance with
the terms of this Indenture, the Security Trust Agreement and the Cash
Management Agreement or by any Person other than the Cash Manager (or, upon the
written direction of the Cash Manager, the Operating Bank) or, in the case of
the Securities Accounts, the Trustee or Guarantor Trustee (in which respect such
Trustee or Guarantor Trustee agrees it is acting as the agent of the Security
Trustee). Each of the parties to this Indenture acknowledges that the terms of
this Indenture contemplate that the Cash Manager will receive certain
information from other parties to this Indenture and the Related Documents in
order for the Cash Manager to be able to perform all or any part of its
obligations hereunder, that the Cash Manager will be able to perform its
obligations hereunder only to the extent such information is provided to the
Cash Manager by the relevant parties and that the Cash Manager may conclusively
rely, absent manifest error, on such information as it receives without
undertaking any independent verification of that information. The Cash Manager
agrees that if it does not receive any such information expected to be received
by it, it will promptly notify the Administrative Agent that it has not received
such information and which party who was to provide such information of such
failure.

          (c) Collections Account. All Collections (including amounts
transferred from the Rental Accounts) shall be, when received, deposited in the
Collections Account, and all cash, Investment and other property in the
Collections Account shall be transferred from the Collections Account in
accordance with the terms of this Indenture.

          (d) Lessee Funded Account. Any Segregated Funds received from time to
time from any Lessee or pursuant to any ACS Group Acquisition Agreement shall be
transferred by the Operating Bank at the written direction of the Cash Manager
(which direction shall be given pursuant to a Written Notice from the
Administrative Agent) from the Collections Account into the related Lessee
Funded Account. The Cash Manager shall not make any withdrawal from, or transfer
from or to, any Lessee Funded Account in respect of (i) any portion of the
Segregated Funds therein consisting of a security deposit except, upon the
termination of the related ACS Group Lease, as provided in such ACS Group Lease
or (ii) any Segregated Funds that is contrary to the requirements of the
respective ACS Group Leases as to Segregated Funds and the

                                                                              69

requirements of the Security Trust Agreement (including the agreement of the
Security Trustee that it designate on its account records that it holds its
interest in each Lessee Funded Account for the benefit of the respective Lessee
in respect of whom such Segregated Funds are held). Without limiting the
foregoing, no cash, Investment and other property in a Lessee Funded Account may
be used to make payments, other than as permitted under Section 3.07 hereof, in
respect of the ACS Group Securities at any time, including after the delivery of
a Default Notice. Any Segregated Funds relating to an expired ACS Group Lease
that remain in a Lessee Funded Account after expiration or termination of such
ACS Group Lease and that are not due and owing to the relevant Lessee under such
expired or terminated ACS Group Lease shall, if so required under the terms of a
subsequent ACS Group Lease, if any, relating to such ACS Group Aircraft, be
credited in a Lessee Funded Account or the Security Deposit Account for the
benefit of the next Lessee of the relevant ACS Group Aircraft to the extent
required under the terms of such subsequent ACS Group Lease and, to the extent
not so required, transferred to the Collections Account. When and as provided in
the Cash Management Agreement the Cash Manager shall cause to be established
such additional Lessee Funded Accounts as requested by the Administrative Agent
and as are provided for in accordance with Section 3.01(a) hereof.

          (e) Security Deposit Account. Any cash security deposits received from
time to time from any Lessee or pursuant to any ACS Group Acquisition Agreement
(other than any cash security deposit required to be Segregated Funds, which
shall be deposited in the related Lessee Funded Account) shall be transferred by
the Operating Bank at the written direction of the Cash Manager (which direction
shall be given pursuant to a Written Notice from the Administrative Agent) from
the Collections Account into the Security Deposit Account. No cash, Investment
and other property in the Security Deposit Account may be used to make payments,
other than as permitted under Section 3.07 hereof, in respect of the ACS Group
Securities at any time, including after the delivery of a Default Notice. Any
security deposits relating to an expired ACS Group Lease that remain in the
Security Deposit Account after expiration or termination of such ACS Group Lease
and that are not due and owing to the relevant Lessee under such expired or
terminated ACS Group Lease shall, if so required under the terms of a subsequent
ACS Group Lease, if any, relating to such ACS Group Aircraft, be credited in the
Security Deposit Account or a Lessee Funded Account for the benefit of the next
Lessee of the relevant ACS Group Aircraft and, to the extent not so required,
transferred to the Collections Account.

          (f) Expense Account. On each Payment Date, such amounts as are
provided in Section 3.08 hereof in respect of the Required Expense Amount and
Permitted Accruals shall be deposited into the Expense Account from the
Collections Account. Expenses shall be paid from the Expenses Account as

Group Aircraft held by the ACS Ireland Group, all Rental Payments and other
amounts received pursuant to any Related Collateral Document related to such ACS
Group Aircraft shall be deposited into the Irish Rental Account. Except with
respect to amounts, if any, that for local tax or other regulatory or legal
reasons must be retained on deposit or as to the transfer of which the Cash
Manager determines (based on information provided to the Cash Manager in a
Written Notice from the Administrative Agent) there is any substantial
uncertainty, all amounts so deposited shall, within one Business Day of their
receipt (or, with respect to any Non-Trustee Account or the Irish Rental
Account, within three Business Days of their receipt), be transferred by the
Cash Manager to the Collections Account. If the Cash Manager determines (based
on

                                                                              70

information provided to the Cash Manager in a Written Notice from the
Administrative Agent) that, for any tax or other regulatory or legal reason, any
such Collections may not be deposited into an account in the name of the
Security Trustee, then, notwithstanding the requirements of Section 3.01(a)
hereof, the relevant ACS Group Member may establish one or more Rental Accounts
(each, a "Non-Trustee Account"), for such Collections in its own name or in the
name of a nominee or trustee acting on its behalf (but subject to the direction
and control of the Cash Manager on behalf of the Security Trustee) at any
Eligible Institution provided that the ACS Group Member that is the lessor under
the relevant Lease is or becomes a party to a Security Document with respect to
such Account.

          (h) Refinancing Account. Upon notice to it of an ACS Group
Refinancing, the Cash Manager shall cause the Operating Bank to establish and
maintain a Refinancing Account pursuant to Section 3.01(a) hereof in the name of
the Security Trustee for the benefit of the Holders of the subclass of ACS Group

Refinancing shall be deposited in the Refinancing Account and shall be held in
such Account until such proceeds are applied to pay the Redemption Price or
Guarantor Redemption Price, as applicable, of and all accrued and unpaid
interest on such ACS Group Securities until such ACS Group Securities are
cancelled by the Trustees and Refinancing Expenses (and any Policy Premium due
and payable to the Policy Provider) with respect thereto (except to the extent
the Directors and the Guarantor Directors have determined, as evidenced by a
Board Resolution and a Guarantor Board Resolution, respectively, to pay the same

as otherwise provided in Section 5.02(f)(ii)(D) hereof.

          (i) Defeasance/Redemption Account. Upon notice to it that any subclass
of ACS Group Securities is to be redeemed pursuant to Section 3.10 hereof or the

Operating Bank to establish and maintain a Defeasance/Redemption Account
pursuant to Section 3.01(a) hereof or of the Guarantor Indenture in the name of
the Security Trustee for the benefit of the Holders of such subclass. All
amounts received for the purpose of any such redemption or defeasance shall be
deposited in the Defeasance/Redemption Account.

          (j) Aircraft Purchase Accounts. As and to the extent provided in
Section 3.04 hereof (or, in the case of any ACS Group Additional Aircraft, in
the terms of any indenture supplemental hereto or to the Guarantor Indenture, as
applicable, or a Board Resolution or Guarantor Board Resolution, as applicable,
with respect to the related ACS Group Additional Securities), an amount equal to
the Aircraft Allocation Amount for each Remaining Aircraft acquired on the
relevant Acquisition Date or, in the case of an Additional ACS Group Aircraft,

transferred from the Collections Account out of the proceeds of the ACS Group
Initial Securities or ACS Group Additional Securities (as the case may be) to
the Aircraft Purchase Account for such ACS Group Aircraft. The amount so

Aircraft not acquired on a Closing Date.

          (k) Aircraft Conversion Account. As and to the extent provided in
Section 3.04(g) and Section 5.02(i) hereof (or in the terms of any indenture
supplement hereto or indenture supplement to the Guarantor Indenture or a Board
Resolution or Guarantor Board Resolution with respect to the related ACS Group
Additional Securities), an amount equal to any expected ACS Group Conversion
Payment (or in the case of a Conversion Election, a portion thereof) will be
transferred from the Collections Account (i) in the event of a Conversion
Election for any Payment Date, in an amount equal to the sum of (A) the
Available Minimum Principal Amount (or a portion thereof) to fund the Allocable
Principal Conversion Amount and (B) the Available Holder Amount (or a portion
thereof) to fund the Allocable Equity Conversion Amount for such Payment Date,
or (ii) out of the proceeds of the ACS Group Additional Securities, in each case
to the Aircraft Conversion Account. The amount so deposited will be held in the
Aircraft Conversion Account and invested in Permitted Account Investments until
applied as provided in Section 3.04 or 3.08 hereof and upon payment of all ACS
Group Conversion Payments required for such Aircraft Conversion, any remaining
amounts in the Aircraft Conversion Account shall be promptly transferred to the
Collections Account. The Administrative Agent shall notify the Security Trustee
and the Cash Manager of the satisfaction or waiver (specifying which) of all
conditions for the payment of any ACS Group Conversion Payment, and no amounts
may be withdrawn or transferred from the Aircraft Conversion Account until
receipt of such notice as to such ACS Group Conversion Payment.

          (l) Securities Account. Upon the issuance of ACS Group Securities of
any subclass for which a Securities Account was not previously established, the
Cash Manager shall cause the Operating Bank to establish and maintain a
Securities Account for such subclass in accordance with Section 3.01(a) hereof
in the name of the Security Trustee for the benefit of the Holders of the ACS

same day shall pay all such amounts to the Holders of such subclass of
Securities as of the related Record Date in accordance with the terms of this
Indenture or the Guarantor Indenture, as applicable; provided that with respect
to the Securities Account for any subclass of ACS Group Class A Securities, so
long as the Pass Through Trustee is the Holder of any subclass of ACS Group
Class A Securities, all amounts in the Securities Account for such subclass of
ACS Group Class A Securities shall be promptly transferred to the Certificate
Account.

          (m) Shareholders Account. Upon the transfer of any amounts to the
Shareholders Account for the Shareholders in accordance with Section 3.08
hereof, the Guarantor Trustee on the same day shall pay all such amounts to the
Shareholders.

          (n) Irish VAT Refund Account. All payments of refunds with respect to
Irish value-added Tax and any similar amounts related to Irish Tax payments
payable to the Issuers or any ACS Group Subsidiary shall be, when received,
deposited in the Irish VAT Refund Account. Funds held in the Irish VAT Refund
Account shall be converted into U.S. dollars with a

                                                                              72

recognized foreign exchange dealer or foreign commercial bank (which may be the
bank where the Irish VAT Refund Account is located or the Cash Manager or an
affiliate). The conversion of currency into U.S. dollars shall be pursuant to
the conversion procedures set forth in Section 13.07. Upon conversion and
receipt of U.S. dollars, the Cash Manager shall cause such amounts to be
deposited from the Irish VAT Refund Account to the Collections Account as soon
as administratively practicable. The cost and expense of any such conversion
shall be added to and reflected in the rate obtained for conversion and in no
event shall the Cash Manager or any of its affiliates be liable in respect of
the exchange rate obtained for any such conversion or any related cost or
expense.

          All amounts held in the Irish VAT Refund Account from time to time
shall remain uninvested pending conversion to U.S. dollars and transfer to the
Collections Account.

          The Administrative Agent shall promptly notify the Cash Manager in
writing of the expected payment of any such refund and the anticipated amount as
set forth in the Administrative Agency Agreement.

          (o) Credit Facility Reserve Account. Following the funding of the
Credit Facility Reserve Account with a Downgrade Drawing, a Final Drawing or a
Non-Extension Drawing, if the Cash Manager determines on any Calculation Date,
after all withdrawals and transfers are made with respect to the Payment Date
related to such Calculation Date, there will be insufficient funds in the
Collections Account (x) to transfer to the Expense Account an amount such that
the amount on deposit therein is equal to the Required Expense Amount for such
Payment Date, (y) to pay Senior Hedge Payments to each applicable Hedge Provider
and (z) to pay the Interest Amount for the ACS Group Subclass A-1 Securities, in
each case as provided in Section 3.08 hereof, the Operating Bank shall withdraw
from the Credit Facility Reserve Account on such Payment Date the lesser of the
amount equal to the shortfall in making the payments set forth in clauses (x),
(y) and (z) above and the amount on deposit therein. The amount so withdrawn
shall be applied in the following manner: FIRST, to the Expense Account an
amount such that the amount on deposit therein is at least equal to the Required
Expense Amount for such Payment Date and SECOND, in no order of priority inter
se, but pro rata, (A) to the Securities Accounts for the ACS Group Subclass A-1
Securities, the Interest Amount on each such subclass of ACS Group Class A
Securities in no order of priority inter se, but pro rata according to the
amount of accrued and unpaid interest on the ACS Group Subclass A-1 Securities
and (B) pro rata, to any Hedge Provider, an amount equal to any Senior Hedge
Payment due from any ACS Group Member pursuant to any Hedge Agreement.

          (p) Senior Cash Collateral Account. (A) If the Cash Manager determines
on any Calculation Date that, on any Payment Date after making all payments and
transfers to be made with respect to such Payment Date (for the avoidance of
doubt, prior to any drawings under the Initial Credit Facility or the Policy
and/or withdrawals, if any, from the Credit Facility Reserve Account), there are
insufficient funds in the Collections Account (x) to transfer to the Expense
Account an amount such that the amount on deposit therein is equal to the
Required Expense Amount, (y) to pay Senior Hedge Payments to each applicable
Hedge Provider and (z) to pay the Interest Amount for each subclass of ACS Group
Class A Securities, in each case as provided in Section 3.08, the Cash Manager
shall so notify the Trustee and the Guarantor Trustee and direct the Operating
Bank in writing on such Payment Date to withdraw from the Senior Cash

                                                                              73

Collateral Account the lesser of an amount equal to the shortfall in making the
payments set forth in clauses (x), (y) and (z) above and the amount on deposit
therein. The amount so withdrawn shall be applied, FIRST, to the Expense Account
an amount such that the amount on deposit therein is at least equal to the
Required Expense Amount and SECOND, in no order of priority inter se, but pro
rata, (A) to the Securities Accounts for each subclass of ACS Group Class A
Securities, the Interest Amount on such subclass of ACS Group Class A Securities
in no order of priority inter se, but pro rata according to the amount of
accrued and unpaid interest on such subclass of ACS Group Class A Securities;
and (B) pro rata, to any Hedge Provider, an amount equal to any Senior Hedge
Payment due from any ACS Group Member pursuant to any Hedge Agreement. If the
Cash Manager determines that, on any Payment Date, the amount on deposit in the
Senior Cash Collateral Account, after making any withdrawals therefrom to be
made on such Payment Date, exceeds the aggregate Outstanding Principal Balance
of the ACS Group Class A Securities, the Cash Manager shall so notify the
Trustee and Guarantor Trustee in writing and, upon receipt of written consent of
the Issuer and the Guarantor, direct the Operating Bank in writing to withdraw
the collected credit balance of the Senior Cash Collateral Account and apply
such balance, FIRST, to the Securities Accounts for each subclass of ACS Group
Class A Securities, in the order of priority by subclass set forth in Section
3.09 hereof, an amount equal to the Outstanding Principal Balance of each such
subclass and SECOND, to the Collections Account, for application on the next
succeeding Payment Date in accordance with Section 3.08 hereof (any such
application, a "Senior Cash Collateral Event"). Unless applied in connection
with a Senior Cash Collateral Event, no amount in the Senior Cash Collateral
Account shall be available for any shortfall in the payment of principal of the
ACS Group Class A Securities. Amounts deposited in the Senior Cash Collateral
Account are not subject to the payment priorities set forth in Section 3.08
hereof.

          (q) Certificate Account. The proceeds of any Policy Drawing shall be,
when received, deposited in the Certificate Account. Any amounts so paid shall
be distributed by the Pass Through Trustee to the holders of the Certificates in
accordance with the terms of the Pass Through Trust Agreement.

          (r) Additional Cash Collateral Accounts. Upon receipt by the Cash
Manager and the Trustee and Guarantor Trustee of a Board Resolution and
Guarantor Board Resolution providing for the establishment of any additional
Cash Collateral Account as an Eligible Credit Facility for one or more
subclasses of Securities or in respect of any other Obligation, the Cash Manager
shall, by Written Notice, cause the Operating Bank to establish (within three
Business Days of the giving of such Written Notice) and maintain such Cash
Collateral Account pursuant to Section 3.01(a) hereof in the name of the
Security Trustee for the benefit of the Holders of the ACS Group Securities of
each such subclass and/or the Secured Parties holding such other Obligation
(and, with respect to any additional Cash Collateral Account to be an Eligible
Credit Facility (other than any Cash Collateral Account in respect of which (a)
amounts will be deposited therein and (b) there is no obligation to reimburse
any Person in respect of such amounts), upon receipt of the prior written
consent of the Initial Credit Facility Provider and the Policy Provider to such
additional Cash Collateral Account). All amounts provided in connection with any
such Board Resolution and Guarantor Board Resolution for deposit in such Account
and all amounts to be deposited in such Account under Section 3.08 hereof as an
Eligible Credit Facility shall be held in such Cash Collateral Account for
application, and all replenishment shall be made, in accordance with the terms
of the Board Resolution and

                                                                              74

Guarantor Board Resolution relating to such Eligible Credit Facility, which
Board Resolution and Guarantor Board Resolution shall include the basis of any
replenishment of the Cash Collateral Account.

          (s) Guarantor Indenture. For the avoidance of doubt, (a) references to
this Section 3.01 shall include reference to the equivalent Section 3.01 in the
Guarantor Indenture and (b) the Accounts under this Indenture shall be the same
accounts, with such names and for such purposes, as the "Accounts" under the
Guarantor Indenture.

     Section 3.02 Investments of Cash. (a) For so long as any ACS Group
Securities remain Outstanding, the Cash Manager, on behalf of the Security
Trustee, shall, or shall direct the Operating Bank in writing to, invest and
reinvest, at the written direction of the Issuers, the funds on deposit in the
Accounts in Permitted Account Investments; provided, however, that the Initial
Credit Facility Provider shall be entitled to direct the Cash Manager to invest
the amounts standing (if any) in the Credit Facility Reserve Account in
Permitted Account Investments; provided further that following the giving of a
Default Notice or during the continuance of an Acceleration Default, the Cash
Manager shall invest such amount at the written direction of the Security
Trustee in Permitted Account Investments described in clause (d) of the
definition thereof (but in the case of a Lessee Funded Account only to the
extent any such investment credited to such Lessee Funded Account is permitted
by the ACS Group Leases pursuant to which such funds were received) from the
time of receipt thereof until such time as such amounts are required to be
distributed pursuant to the terms of this Indenture and the Guarantor Indenture.
The Cash Manager shall make such investments and reinvestments, and the Issuer,
the Initial Credit Facility Provider and/or the Security Trustee as specified in
the immediately preceding sentence shall provide such direction, in accordance
with the terms of the following provisions:

          (i) the Permitted Account Investments shall have maturities and other
terms such that sufficient funds shall be available to make required payments
pursuant to this Indenture and the Guarantor Indenture (A) before the next
Payment Date after which such investment is made, in the case of investments of
funds on deposit in the Collections Account and the Expense Account, or (B) in
accordance with a Written Notice provided by the Administrative Agent, the
requirements of the relevant ACS Group Leases or ACS Group Aircraft Agreements,
in the case of investments of funds on deposit in the Lessee Funded Accounts or
the Security Deposit Account; provided that an investment maturing within one
year of the date of investment shall nevertheless be a Permitted Account
Investment if it has been acquired with funds which are not reasonably
anticipated, at the discretion of the Cash Manager (at the direction of the
Administrative Agent), to be required to be paid to any other Person or
otherwise transferred from the applicable Account prior to such maturity;

          (ii) if any funds to be invested are not received in the Accounts by
1:00 p.m. (New York City time) on any Business Day, such funds shall, if
possible, be invested in overnight Permitted Account Investments described in
clause (d) of the definition thereof; provided that none of the Trustee, the
Guarantor Trustee or the Security Trustee shall be liable for any losses
Incurred in respect of the failure to invest funds not thereby received; and

          (iii) if required by the terms of a ACS Group Lease as set forth in a
Written Notice from the Administrative Agent to the Cash Manager, any
investments of funds on deposit

                                                                              75

in a Lessee Funded Account or the Security Deposit Account shall be made on
behalf of the relevant Lessee in such investments as may be required thereunder.

          (b) It is understood and agreed that the Cash Manager or its
affiliates are permitted to receive additional compensation that could be deemed
to be in the Cash Manager's economic self-interest for (1) serving as investment
adviser, administrator, shareholder servicing agent, custodian or sub-custodian
with respect to certain of the Permitted Account Investments, (2) using
affiliates to effect transactions in certain Permitted Account Investments and
(3) effecting transactions in Permitted Account Investments.

          (c) Except as provided expressly hereunder, the Cash Manager shall
have no obligation to invest and reinvest any cash held in the Accounts in the
absence of timely and specific written investment direction from the Issuers (or
the Administrative Agent), the Initial Credit Facility Provider or the Security
Trustee, as the case may be. In no event shall the Cash Manager be liable for
the selection of investments or for investment losses incurred thereon. The Cash
Manager shall have no liability in respect of losses incurred as a result of the
liquidation of any investment prior to its stated maturity or the failure of
Issuers to provide timely written investment direction.

     Section 3.03 Closing Date Deposits, Withdrawals and Transfers. The Cash
Manager shall, on each Closing Date, at the written direction of the Issuer,

the date which is the third Business Day prior to the related Payment Date, the
Cash Manager shall provide notice to the Issuer and the Guarantor of its
calculations of (i) the amount (the "Available Minimum Principal Amount")
available (after giving effect to all Prior Ranking Amounts) to pay the Minimum
Principal Payment Amount for the ACS Group

Class A Securities (for application in accordance with Section 3.08(a)) for such
Payment Date and (ii) the Allocable Principal Conversion Amount with respect to
any proposed ACS Group Aircraft Conversion and whether the Available Minimum
Principal Amount (after giving effect to any prior transfer to the Aircraft
Conversion Account of any Available Minimum Principal Amounts in respect of a
particular Aircraft Conversion) is sufficient to fund such Allocable Principal
Conversion Amount in full. As soon as practicable after receipt of such
calculations, but in no event later than 12:00 p.m. (New York City time) on the
date which is the second Business Day prior to the related Payment Date, each of
the Issuer and the Guarantor (or the Administrative Agent on their behalf) shall
advise the Cash Manager as to whether the Available Minimum Principal Amount
should be applied in accordance with Section 3.08(a) towards the Minimum
Principal Payment Amount payable for such Payment Date or should be transferred
to the Aircraft Conversion Account (such election to transfer the Available
Minimum Principal Amount (or such lesser amount as may be necessary to fund the
Allocable Principal Conversion Amount for such ACS Group Aircraft Conversion) to
the Aircraft Conversion Account, a "Principal Conversion Election"). For the
avoidance of doubt, the sum of the Available Minimum Principal Amount
transferred to the Aircraft Conversion Account in respect of any proposed ACS
Group Aircraft Conversion may not exceed the Allocable Principal Conversion
Amount for such ACS Group Aircraft Conversion. In the absence of a Principal
Conversion Election, the Available Minimum Principal Amount shall be applied in
accordance with the payment priorities set forth in Section 3.08(a) hereof. A
Principal Conversion Election with respect to any ACS Group Aircraft Conversion
in relation to any Payment Date will be only permitted (i) if a Holder
Conversion Election with respect to such ACS Group Aircraft conversion in
relation to such Payment Date is also made and (ii) in the same proportion as
(x) the amount of Available Holder Amount to be transferred to the Aircraft
Conversion Account to fund the Allocable Equity Conversion Amount in respect of
such Holder Conversion Election on such Payment Date bears to (y) such Allocable
Equity Conversion Amount.

          (h) Notification of Calculations in respect of Available Holder
Amounts. So long as a Default Notice has not been issued, an Acceleration
Default has not occurred or a DSCR Failure has not occurred or will not occur on
the next succeeding Payment Date, as soon as practicable after each Calculation
Date, but in no event later than 12:00 p.m. (New York City time) on the date
which is the third Business Day prior to the related Payment Date, the Cash
Manager shall provide notice to the Issuer and the Guarantor of its calculations
of (i) the amount (the "Available Holder Amount") available (after giving effect
to all Prior Ranking Amounts) to pay the Holder of the Class E Securities and
the Shareholders in accordance with Section 3.08(a) for such Payment Date and
(ii) the Allocable Equity Conversion Amount with respect to any proposed ACS
Group Aircraft Conversion and whether such Available Holder Amount (after giving
effect to any prior transfers to the Aircraft Conversion Account of Available
Holder Amounts in respect of a particular ACS Group Aircraft Conversion) is
sufficient to fund such Allocable Equity Conversion Amount in full. As soon as
practicable after receipt of such calculations, but in no event later than 12:00
p.m. (New York City time) on the date which is the second Business Day prior to
the related Payment Date, each of the Issuer and the Guarantor (or the
Administrative Agent on their behalf) shall advise the Cash Manager as to
whether the Available Holder Amount should be paid to the Holders of the Class E
Securities and the Shareholders pro rata according to the Applicable Allocation
Percentage for such Payment Date or should, in lieu of such payment, be
transferred in whole or in part to the Aircraft Conversion

                                                                              83

Account to fund the Allocable Equity Conversion Amount (such election to
transfer the Available Holder Amount (or such lesser amount as may be necessary
to fund the Allocable Equity Conversion Amount for such ACS Group Aircraft
Conversion) to the Aircraft Conversion Account, a "Holder Conversion Election"
and, together with a Principal Conversion Election, a "Conversion Election").
For the avoidance of doubt, the sum of the Available Holder Amount transferred
to the Aircraft Conversion Account in respect of any proposed ACS Group Aircraft
Conversion may not exceed the Allocable Equity Conversion Amount for such ACS
Group Aircraft Conversion. In the absence of a Holder Conversion Election, the
Available Holder Amount shall be applied in accordance with the payment
priorities set forth in Section 3.08(a) hereof.

          (i) Calculations in respect of Policy Drawings. The Cash Manager shall
make the following calculations or determinations in respect of the Policy:

          (i) as soon as practicable after each Calculation Date, but in no
event later than 12:00 p.m. (New York City time) on the date which is the third
Business Day prior to each Regular Distribution Date, determine (after giving
effect to all payments and transfers to be made with respect to such Regular
Distribution Date and the application of Available Collections in accordance
with the applicable payment priorities set forth in Section 3.08 hereof, the
application of Credit Facility Drawings to be made pursuant to the Initial
Credit Facility, any withdrawals from the Credit Facility Reserve Account and
any withdrawals from the Senior Cash Collateral Account pursuant to Section
3.01(p)), whether a shortfall will exist as of such Regular Distribution Date in
the Available Collections and such other amounts to make payment on such Regular
Distribution Date of Accrued Senior Interest due on the Certificates on such
Regular Distribution Date (any such shortfall in respect of accrued and unpaid
interest on the Certificates on any Regular Distribution Date, an "Interest
Shortfall" therefor);

at the direction of the Controlling Party after an Acceleration of the
Securities, but in no event later than 12:00 p.m. (New York City time) on the
date which is the third Business Day prior to the next succeeding Regular
Distribution Date, determine the shortfall, if any, between the Class A Note
Target Price (determined as of the date of disposition) of the disposed Aircraft
(or of the Aircraft owned by the disposed ACS Group Subsidiary) and the Net Sale
Proceeds from the sale or other disposition of such Aircraft (or of such
disposed ACS Group Subsidiary owning such Aircraft) (the "Deficiency Shortfall"
with respect to the next succeeding Regular Distribution Date);

          (iii) as soon as practicable after each Calculation Date on or
following the date that is 24 months after the date (as determined by the Pass
Through Trustee or the Trustee and notified to the Policy Provider in writing)

withdrawals from the Credit Facility Reserve Account and/or the Senior Cash
Collateral Account, in each case, in accordance with the terms hereof) the
shortfall (determined as of such Calculation Date), if any, of Available
Collections and such other amounts for the payment on the next succeeding
Regular Distribution Date of an amount necessary to reduce the then Pool Balance
of the Certificates by the Insured Minimum Principal Payment Amount, if any, of
the ACS Group Subclass A-1 Securities for such Regular Distribution Date (with
respect to any such Regular Distribution Date, a "Minimum Principal Shortfall");

          (iv) as soon as practicable after the Final Maturity Date, but in no
event later than 12:00 p.m. (New York City time) on the date which is the third

application of Available Collections in accordance with the applicable payment
priorities set forth in Section 3.08 hereof on or prior to the Final Maturity
Date and the application of any Credit Facility Drawings (or drawings under any
Replacement Credit Facility), any withdrawals from the Credit Facility Reserve
Account and any withdrawals from the Senior Cash Collateral Account as set forth
in Section 3.01(p), in each case, on such Final Maturity Date) (determined as of
the Final Maturity Date) whether any shortfall will exist in the amount
necessary for the payment in full of the Pool Balance of the Certificates on the
Legal Final Distribution Date therefor together with accrued and unpaid interest
thereon (at the Stated Rate of Interest for the Certificates) (any such
shortfall on the Legal Final Distribution Date, the "Final Amount" therefor);
and

          (v) as promptly as practicable after the date of any Avoided Payment,
calculate the amount of such Avoided Payment.

available in the Defeasance/Redemption Account or, in the case of a Refinancing,
the Refinancing Account, for such purpose, if any, other than, in either such
case, any funds constituting part of the Available Collections, at the
Redemption Price plus any accrued and unpaid interest (after giving effect to
any payment thereof on such Redemption Date under Section 3.08 hereof) on the
Securities to be redeemed to the Redemption Date; provided that such a
redemption may only occur upon the prior written consent of the Policy Provider
(except that a redemption in full of the ACS Group Subclass A-1 Securities shall
not require any such consent if a Policy Non-Consent Event occurs in connection
with such redemption) and after the giving of a Default Notice or the
Acceleration of any Securities, the Securities may be redeemed only in whole but
not in part pursuant to this Section 3.10(a); provided further that Written
Notice of any such Redemption shall be given by the Issuer (or the
Administrative Agent on its behalf) to the Trustee not less than 30 days and not
more than 45 days prior to such Redemption Date and, for so long as any
Securities are listed on the Alternative Securities Market

                                                                              94

          (b) Redemption for Taxation Reasons. Subject to the provisions of
Section 3.10(c) hereof, if, at any time,

          (i) the Issuer is, or on the next succeeding Payment Date will be,
     required to make any withholding or deduction under the laws or regulations
     of any applicable tax authority with respect to any payment on any subclass
     of Securities; or

          (ii) the Issuer is or will be subject to any circumstance (whether by
     reason of any law, regulation, regulatory requirement or double-taxation
     convention, or the interpretation or application thereof, or otherwise)
     that has resulted or will result in the imposition of a Tax (whether by
     direct assessment or by withholding at source) or other similar imposition
     by any jurisdiction that would (A) materially increase the cost to the
     Issuer of making payments in respect of any subclass of Securities or of
     complying with its obligations under or in connection with the Securities;
     (B) materially increase the operating or administrative expenses of the
     Issuer; or (C) otherwise obligate the Issuer or any of its subsidiaries to

     any sum received or receivable by the Issuer, or by the Cash Manager on
     behalf of the ACS Ireland Group as contemplated by the Cash Management
     Agreement,

then the Issuer shall inform the Trustee in writing at such time of any such
requirement or imposition and shall use commercially reasonable efforts to avoid
the effect of the same; provided that no actions shall be taken by the Issuer to
avoid such effects without receipt of a Rating Agency Confirmation and the prior
written consent of the Policy Provider. If, after using its commercially
reasonable efforts to avoid the adverse effects described above, any ACS Ireland
Group Member has not avoided such effects, the Issuer may, at its election,
redeem the Securities on any Payment Date, in whole, at the Outstanding
Principal Balance thereof plus accrued and unpaid interest (after giving effect
to any payment thereof on such Redemption Date under Section 3.08 hereof)
thereon, the Required Expense Amount and all unpaid Policy Provider Obligations,
Credit Facility Obligations and any amounts payable to any Hedge Provider as of
the Redemption Date to such Payment Date but without premium; provided, however,
that any such Redemptions may not occur more than 30 days prior to such time as
the requirement or imposition described in (i) or (ii) above is to become
effective and each of the Trustee and the Policy Provider shall have received a
certification from the Issuer certifying that the applicable ACS Ireland Group
Member has been unable, after using such commercially reasonable efforts, to
avoid the adverse effects described above; and provided further that Written
Notice of any such Redemption shall be given by the Issuer (or the
Administrative Agent on its behalf) to the Trustee and the Policy Provider not
less than 30 days and not more than 45 days prior to the Redemption Date for
such Redemption and, for so long as any Securities are listed on the Alternative
Securities Market of the Irish Stock Exchange, to the Listing Agent and the
Alternative Securities Market of the Irish Stock Exchange not less than 30 days
and not more than 45 days prior to the Redemption Date for such Redemption.

                                                                              95

Securities under Section 3.10(a) or 3.10(b) hereof (a "Redemption") to each
Holder of Securities and the Policy Provider, at least 20 days before the
Redemption Date for such Redemption. Except in the case of a Refinancing, the
Trustee shall not deliver any notice under this Section 3.10(c) unless and until
the Trustee shall have received certification that all conditions precedent to
such Redemption have been satisfied and evidence satisfactory to it that the
amounts required to be deposited pursuant to Section 3.10(d) hereof are, or will
on or before the Redemption Date be, deposited in the Defeasance/Redemption
Account. Each notice in respect of a Redemption given pursuant to this Section
3.10(c) shall state (i) the applicable Redemption Date, (ii) the Trustee's
arrangements for making payments in respect of such Redemption, (iii) the
Redemption Price or the Outstanding Principal Balance of each subclass of
Securities to be redeemed and accrued and unpaid interest, (iv) in the case of a

Redemption Price plus accrued and unpaid interest on such Securities and (v) in
the case of a Redemption of the Securities of any subclass in whole, that,
unless the Issuer defaults in the payment of the Redemption Price and any
accrued and unpaid interest on the Securities to be redeemed, interest on the
subclass of Securities called for Redemption shall cease to accrue on and after
the Redemption Date.

          (d) Deposit of Redemption Amount. On or before 10:00 a.m. (New York
City time) on the fifth day preceding any Redemption Date in respect of a
Redemption under Section 3.10(a) hereof, the Issuer shall, to the extent an

therein, deposit or cause to be deposited in the Defeasance/Redemption Account
or, in the case of a Refinancing, the Refinancing Account, other than, in either
case, any funds constituting part of the Available Collections, an amount in
immediately available funds equal to such amount. On or before 10:00 a.m. (New
York City time) on the fifth day preceding any Redemption Date in respect of a

on such Redemption Date under Section 3.08 hereof) and all unpaid Policy
Provider Obligations (including any Policy Premium and any Policy Redemption

Date (unless there shall be a default in the payment of the applicable amount to
be redeemed) such principal amount shall cease to bear interest.

                                                                              96

Upon surrender of any Security for redemption in accordance with such notice,
the Redemption Price or the Outstanding Principal Balance (as applicable) of
such Security, together with accrued and unpaid interest on such Security shall
be paid as provided for in this Section 3.10. If any Security to be redeemed
shall not be so paid upon surrender thereof for redemption, the amount in
respect thereof shall continue to bear interest until paid from the Redemption
Date at the interest rate or Periodic Return applicable to such Security.

or Refinancing Securities, subject to Sections 5.02(f) and 5.02(h) hereof (as
applicable), the Note Pool Factors and Extended Note Pool Factors for any
subclass of Securities may be adjusted or, in the case of any new subclass of
Securities, determined to take into account such Permitted Additional Aircraft
Acquisition or the issuance of such Refinancing Securities in the manner
specified in the Board Resolution providing for such action subject to the prior
written consent of the Policy Provider and the Initial Credit Facility Provider;
provided that no Note Pool Factor or Extended Note Pool Factor for any subclass
of Securities may be adjusted so as to change the original Average Life of the
affected subclass of Securities or alter the rate at which such subclass of
Securities was originally scheduled to amortize. The Administrative Agent shall
include such adjusted Note Pool Factors, Extended Note Pool Factors and Minimum
Target Principal Balances in each Quarterly Report and Annual Report.

     Section 3.12 Initial Credit Facility.

          (a) Credit Facility Drawings. If the Cash Manager determines in
accordance with Section 3.06(f) hereof that after making all withdrawals (prior
to any drawings under the Policy but after any withdrawals from the Senior Cash
Collateral Account and the Credit Facility Reserve Account) and transfers to be
made with respect to the applicable Payment Date, there is (x) a Required
Expenses Shortfall, (y) a Senior Hedge Payments Shortfall and/or (z) a Credit
Facility Interest Class A Shortfall, in each case as calculated in Section
3.06(f) hereof, the Cash Manager shall so notify the Trustees in writing and
shall, no later than 1:00 p.m. (New York City time) three Business Days prior to
such Payment Date, request a drawing (each such drawing, a "Credit Facility
Drawing") under the Initial Credit Facility, to be paid on or prior to such
Payment Date, in an amount equal to the lesser of (a) the aggregate amount of
the shortfall from clauses (x), (y) and (z) above and (b) the Available Amount
under the Initial Credit Facility.

          (b) Application of Credit Facility Drawings. The proceeds of any
Credit Facility Drawing shall be deposited into the Initial Liquidity Payment
Account and withdrawn by the Operating Bank, upon Written Notice from the Cash
Manager, for application on the applicable Payment Date in the following manner:

                                                                              97

          (c) Downgrade Drawings. The Initial Credit Facility Provider shall
notify the Issuers, the Cash Manager and the Policy Provider promptly upon the
occurrence of a Downgrade Event. If at any time a Downgrade Event has occurred
and within 10 days after notice of such event (but not later than the expiration
date of the Initial Credit Facility) (i) the Initial Credit Facility Provider or
the Issuer or the Guarantor does not arrange to replace the Initial Credit
Facility with a Replacement Credit Facility, (ii) the Initial Credit Facility
Provider shall not have received a Rating Agency Confirmation with respect to
the Downgrade Event and the written consent of the Policy Provider to the
retention of such Initial Credit Facility Provider shall not have been obtained
or (iii) the Policy Provider shall not have confirmed in writing that such
downgrading will not constitute a Downgrade Event, on such 10th day (or if such
10th day is not a Business Day, on the next succeeding Business Day) (or, if
earlier, the expiration date of the Initial Credit Facility), then the Cash
Manager shall, upon the occurrence of a Downgrade Event with respect to the
Initial Credit Facility, request a drawing in accordance with and to the extent
permitted by the Initial Credit Facility (such drawing, a "Downgrade Drawing")
of the Available Amount thereunder. Amounts drawn pursuant to a Downgrade
Drawing shall be deposited into the Credit Facility Reserve Account.

          (d) Non-Extension Drawings. If the Initial Credit Facility is
scheduled to expire on a date (the "Stated Expiration Date") prior to the date
that is 15 days after the Final Maturity Date with respect to the ACS Group
Subclass A-1 Securities, then, no earlier than the 60th day and no later than
the 30th day prior to the applicable Stated Expiration Date then in effect, the
Cash Manager shall request that the Initial Credit Facility Provider extend the
Stated Expiration Date until the earlier of (i) the date which is 15 days after
such Final Maturity Date with respect to the ACS Group Subclass A-1 Securities
and (ii) the date that is immediately preceding the 364th day occurring after
the Stated Expiration Date then in effect (unless the obligations of the Initial
Credit Facility Provider under the Initial Credit Facility are earlier
terminated in accordance with the Initial Credit Facility). If on or before the
date which is 10 days prior to the Stated Expiration Date, (A) the Initial
Credit Facility shall not have been replaced in accordance with Section 3.12(e)
hereof or (B) the Initial Credit Facility Provider fails irrevocably and
unconditionally to advise the Cash Manager that such Stated Expiration Date then
in effect shall be so extended (whether or not the Cash Manager has in fact
requested an extension), the Cash Manager shall immediately, in accordance with
the terms of the Initial Credit Facility (a "Non-Extended Facility"), request a
drawing under such Initial Credit Facility (such drawing, a "Non-Extension
Drawing") for the Available Amount thereunder. Amounts drawn pursuant to a
Non-Extension Drawing shall be deposited into the Credit Facility Reserve
Account.

          (e) Issuance of Replacement Credit Facility.

          (i) If the Initial Credit Facility Provider shall determine not to
extend the Initial Credit Facility in accordance with Section 3.12(d) hereof,
then either the Initial Credit Facility Provider or either the Issuer or the
Guarantor may, at their respective options, arrange for a Replacement Credit
Facility to replace the Initial Credit Facility during the period no earlier
than 35 days and no later than 10 days prior to the then effective Stated
Expiration Date.

          (ii) If a Downgrade Event shall have occurred with respect to the
Initial Credit Facility in accordance with Section 3.12(c) hereof, then either
the Initial Credit Facility Provider or the Issuer or the Guarantor may, at
their respective options, arrange for a Replacement Credit

                                                                              98

Facility to replace the Initial Credit Facility within 10 days after receiving
notice of such Downgrade Event (but not later than the expiration date of the
Initial Credit Facility); provided, however, that the Initial Credit Facility
Provider may, at its option, arrange for a Replacement Credit Facility at any
time following a Downgrade Drawing so long as neither the Issuer nor the
Guarantor has already arranged for a Replacement Credit Facility.

          (iii) (A) At any time after the then Stated Expiration Date of the
Initial Credit Facility which has been extended for a period in excess of a
364-day period, the Initial Credit Facility Provider may, at its option, arrange
for a Replacement Credit Facility to replace the Initial Credit Facility.

          (B) No Replacement Credit Facility arranged by the Initial Credit
Facility Provider or the Issuer or the Guarantor in accordance with clauses
(e)(i), (e)(ii) and (e)(iii)(A) above shall become effective and no such
Replacement Credit Facility shall be deemed an Eligible Credit Facility under
this Indenture, unless and until (y) each of the conditions referred to in
subclause (C) below shall have been satisfied, and (z) in the case of a
Replacement Credit Facility arranged by the Initial Credit Facility Provider,
such Replacement Credit Facility is acceptable to the Issuer and the Guarantor.

          (C) In connection with the issuance of each Replacement Credit
Facility, (x) the Cash Manager shall, prior to the issuance of such Replacement
Credit Facility, have received a Rating Agency Confirmation with respect to the
Certificates (without regard to any downgrading of any rating of the Initial
Credit Facility Provider being replaced pursuant to Section 3.12(c) hereof and
without regard to the Policy), (y) upon receipt of a Written Notice from the
Administrative Agent to the Cash Manager setting forth the amount of Credit
Facility Obligations then owing to the replaced Initial Credit Facility
Provider, the Cash Manager shall direct the Operating Bank pursuant to a Written
Notice of the Cash Manager setting forth the amount of Credit Facility
Obligations then owing to the replaced Initial Credit Facility Provider to pay
to the replaced Initial Credit Facility Provider all Credit Facility Obligations
then owing to the replaced Initial Credit Facility Provider and upon receipt of
such Written Notice, the Operating Bank shall pay such amount to the Initial
Credit Facility Provider (which payment shall be made first from available funds
in the Credit Facility Reserve Account, and thereafter from any other available
source, including, without limitation, a drawing under the Replacement Credit
Facility) and (z) the issuer of the Replacement Credit Facility shall deliver
the Replacement Credit Facility to the Cash Manager, together with a legal
opinion opining that such Replacement Credit Facility has been duly authorized,
executed and delivered by, and is an enforceable obligation of, such Replacement
Credit Facility Provider, such legal opinion to be reasonably satisfactory to
the Policy Provider unless the legal opinion of counsel to the Replacement
Credit Facility Provider is in form and substance substantially the same as the
legal opinion of counsel to the Initial Credit Facility Provider delivered on
the Initial Closing Date.

          (D) Upon satisfaction of the conditions set forth in clauses (B) and
(C) of this Section 3.12(e)(iii) with respect to a Replacement Credit Facility,
(w) the replaced Initial Credit Facility shall terminate, (x) the Cash Manager
shall, if and to the extent so requested by the Issuer or the Guarantor or the
Initial Credit Facility Provider being replaced, execute and deliver any
certificate or other instrument furnished to it required in order to terminate
the replaced Initial Credit Facility, shall surrender the replaced Initial
Credit Facility to the Initial Credit

                                                                              99

Facility Provider being replaced and shall execute and deliver the Replacement
Credit Facility, (y) each of the parties hereto shall enter into any amendments
to this Indenture, the Guarantor Indenture and any other Related Documents
necessary to give effect to (1) the replacement of the applicable Initial Credit
Facility Provider with the applicable Replacement Credit Facility Provider and
(2) the replacement of the applicable Initial Credit Facility with the
applicable Replacement Credit Facility and (z) such Replacement Credit Facility
Provider shall be deemed to be an Eligible Provider with the rights and
obligations of the Initial Credit Facility Provider hereunder and under the
other Related Documents and such Replacement Credit Facility shall be deemed to
be an Eligible Credit Facility (and, if so designated by a Board Resolution and
Guarantor Board Resolution, deemed to be the Initial Credit Facility) hereunder
and under the other Related Documents.

          (f) Credit Facility Reserve Account; Withdrawals; Investments. All
amounts drawn under the Initial Credit Facility by the Cash Manager pursuant to
Section 3.12(c), 3.12(d) or 3.12(i) hereof shall be deposited by the Cash

Credit Facility Reserve Account, including any amount deposited in accordance
with clause (iv) of Section 3.08(a) hereof, shall be invested and reinvested in
accordance with Section 3.02 hereof. Upon a request by the Initial Credit
Facility Provider, the Cash Manager shall provide the Initial Credit Facility
Provider with the amount of Investment Earnings held in the Credit Facility

Credit Facility Provider all Investment Earnings on amounts on deposit in the
Credit Facility Reserve Account. Amounts on deposit in the Credit Facility
Reserve Account shall be withdrawn by or at the direction of the Cash Manager
under the following circumstances:

          (i) in accordance with Section 3.01(o) hereof;

          (ii) on any Payment Date, if the amount in the Credit Facility Reserve
Account exceeds the Required Amount therefor, then the Cash Manager shall direct
the Operating Bank to withdraw, upon Written Notice from the Cash Manager, from
the Credit Facility Reserve Account such excess and pay such amount to the
Initial Credit Facility Provider;

          (iii) if a Replacement Credit Facility is established following the
date on which funds have been deposited into the Credit Facility Reserve
Account, the Cash Manager shall direct the Operating Bank to withdraw, upon
Written Notice from the Cash Manager, all amounts on deposit in the Credit
Facility Reserve Account and shall pay such amounts to the replaced Initial
Credit Facility Provider until all Credit Facility Obligations owed to such
Person shall have been paid in full, and shall deposit any remaining amount in
the Collections Account;

          (iv) upon the payment in full of the Outstanding Principal Balance of,
and accrued and unpaid interest on, the ACS Group Subclass A-1 Securities, the
Cash Manager shall direct the Operating Bank to withdraw, upon Written Notice
from the Cash Manager, all amounts from the Credit Facility Reserve Account and
pay such amounts to the Initial Credit Facility Provider until all Credit
Facility Obligations owed to such Initial Credit Facility Provider have been
paid in full, and shall deposit any remaining amount in the Collections Account;
and

                                                                             100

          (v) 15 days after the Final Maturity Date with respect to the ACS

          (g) Reinstatement. With respect to any Credit Facility Drawing under
the Initial Credit Facility, upon the reimbursement to the Initial Credit
Facility Provider in full or in part of the amount of such Credit Facility
Drawing, together with any accrued interest thereon, the Available Amount of the
Initial Credit Facility shall be reinstated by an amount equal to the amount of
such Credit Facility Drawing so reimbursed to the Initial Credit Facility
Provider but not to exceed the Maximum Commitment; provided, however, that the
Initial Credit Facility shall not be so reinstated in part or in full at any
time if (x) a Credit Facility Event of Default shall have occurred and be
continuing or (y) a Downgrade Drawing, Non-Extension Drawing or Final Drawing
shall have occurred.

          (h) Reimbursement. The amount of each Credit Facility Drawing under
the Initial Credit Facility and any amounts withdrawn from the Credit Facility
Reserve Account following a Downgrade Drawing, Non-Extension Drawing or a Final
Drawing shall be due and payable, together with interest thereon, on the dates
and at the rates, respectively, provided in the Initial Credit Facility but only
to the extent that Available Collections are sufficient to pay such amounts in
the order of priority set forth in Section 3.08 hereof.

          (i) Final Drawing. Upon receipt from the Initial Credit Facility
Provider of a Termination Notice with respect to the Initial Credit Facility,
the Cash Manager shall, not later than the date specified in such Termination
Notice, in accordance with the terms of the Initial Credit Facility, request a

"Final Drawing"). Proceeds of a Final Drawing shall be deposited into the Credit
Facility Reserve Account for application in accordance with Section 3.12(f)
hereof.

          (j) Initial Credit Facility Provider Consent. To the extent that the
Initial Credit Facility Provider's consent or approval (including with respect
to any amendment) is required under this Indenture, the Guarantor Indenture or
any other Related Document, such consent is not required in the event that (x)
no ACS Group Subclass A-1 Securities are Outstanding and (y) no Credit Facility
Advance Obligations are due and owing to the Initial Credit Facility Provider
(and, in the case of the issuance of ACS Group Additional Securities, if any, an
Initial Credit Facility Non-Consent Event has occurred).

     Section 3.13 Eligible Credit Facilities. Notwithstanding Section 3.08
hereof, Article X hereof, or anything else to the contrary contained in the
Indenture, Guarantor Indenture or the Security Trust Agreement, all amounts
available in any Cash Collateral Account or drawn against any other Eligible
Credit Facility (other than the Initial Credit Facility) shall be paid to
Holders of the subclass of ACS Group Securities (and holders of other

established except to the extent otherwise provided in the Board Resolutions and
Guarantor Board Resolutions providing for such Eligible Credit Facility.

                                                                             101

     Section 3.14 The Policy. The Policy Provider shall issue a Policy in favor
of the Drawing Agent for the benefit of the holders of the Certificates, and the
following shall apply to the Policy and the Certificates subject thereto:

          (a) Interest Drawings. If the Cash Manager determines that there is an
Interest Shortfall with respect to any Regular Distribution Date (other than the
Legal Final Distribution Date and the date of the Final Policy Election) in
respect of the Certificates (calculated as provided in Section 3.06(i) hereof),
the Cash Manager shall, prior to 12:00 p.m. (New York City time) on the third

request a Policy Drawing under the Policy (for payment into the Certificate
Account) in an amount equal to such Interest Shortfall (each, an "Interest
Drawing"). Any request received after 12:00 p.m. (New York City time) on any
Business Day shall be deemed to have been received by the Policy Provider on the
next Business Day. Upon receipt of any such request for a Policy Drawing, the
Policy Provider or its fiscal agent shall pay, no later than 12:00 p.m. (New
York City time) on the later of (i) the applicable Regular Distribution Date and
(ii) the second Business Day following the Business Day on which the Policy
Provider received the Drawing Agent's request referred to above, into the
Certificate Account, the amount of the Interest Shortfall with respect to such
Regular Distribution Date. Upon receipt, the Pass Through Trustee shall direct
the payment of the amount in the Certificate Account to the holders of the
Certificates in payment of the Interest Shortfall therefor.

          (b) Proceeds Deficiency Drawing. If at any time after the Acceleration
of the Securities, there is a sale or other disposition of an ACS Group Aircraft
(not including any ACS Group Aircraft acquired by way of contribution) or of an
ACS Group Subsidiary that owns an ACS Group Aircraft (not including any ACS
Group Aircraft acquired by way of contribution) by, on behalf of or at the
direction of the Controlling Party, and there is a Deficiency Shortfall
resulting therefrom (calculated as provided in Section 3.06(i)(ii)), the Cash
Manager shall, prior to 12:00 p.m. (New York City time) on the third Business
Day prior to the next succeeding Regular Distribution Date, instruct the Drawing
Agent to request and the Drawing Agent, no later than 12:00 p.m. (New York City
time) on the second Business Day prior to such Regular Distribution Date, shall
request a Policy Drawing (each a "Deficiency Drawing") under the Policy in an
amount equal to the Deficiency Shortfall (for payment into the Certificate
Account) with respect to such Regular Distribution Date. Any request received
after 12:00 p.m. (New York City time) on any Business Day shall be deemed to
have been received by the Policy Provider on the next Business Day. Upon receipt
of any such request, the Policy Provider or its fiscal agent shall, no later
than 12:00 p.m. (New York City time) on the later of (i) the applicable Regular
Distribution Date and (ii) the second Business Day following the Business Day on
which the Policy Provider received the Drawing Agent's request referred to
above, pay under the Policy, in respect of the Certificates, an amount equal to
the Deficiency Shortfall for the Certificates with respect to such Regular
Distribution Date. Upon receipt, the Pass Through Trustee shall direct the
payment of the amount in the Certificate Account to the holders of the
Certificates in payment of the Deficiency Shortfall therefor.

          (c) No Proceeds Drawing. If, on any Calculation Date (other than the
Calculation Date occurring immediately prior to the Legal Final Distribution
Date of the

                                                                             102

Certificates) falling on or after the date that is 24 months after the date of
the occurrence of an Event of Default under Section 4.01(a) or Section 4.01(b)
hereof or an Acceleration of the Securities (the "Non-Performance Period"),
there is a Minimum Principal Shortfall in respect of the Certificates for the
then next succeeding Regular Distribution Date (calculated as provided in
Section 3.06(i)(iii) hereof), the Cash Manager shall, no later than 12:00 p.m.
(New York City time) on the third Business Day prior to such Regular
Distribution Date, instruct the Drawing Agent to request and the Drawing Agent
shall, no later than 12:00 p.m. (New York City time) on the second Business Day
prior to such Regular Distribution Date, request, a Policy Drawing (each, a "No
Proceeds Drawing") under the Policy (for payment into the Certificate Account)
in an amount equal to the Minimum Principal Shortfall with respect to such
Regular Distribution Date. Any request received after 12:00 p.m. (New York City
time) on any Business Day shall be deemed to have been received by the Policy
Provider on the next Business Day. Upon receipt of such request, the Policy
Provider or its fiscal agent shall, no later than 12:00 p.m. (New York City
time) on the later of (i) the applicable Regular Distribution Date and (ii) the
second Business Day following the Business Day on which the Policy Provider
receives the Drawing Agent's request referred to above, pay under the Policy an
amount equal to the Minimum Principal Shortfall with respect to such Regular
Distribution Date. Upon receipt, the Pass Through Trustee shall direct the
payment of the amount in the Certificate Account to the holders of the
Certificates in payment of the Minimum Principal Shortfall therefor.

          Notwithstanding the preceding paragraph, with respect to any Regular
Distribution Date occurring on or after the date of the occurrence of an Event
of Default with respect to the ACS Group Subclass A-1 Securities continuing on
the date of a Final Policy Election, and the occurrence of the earlier of (x)
the date of a Policy Drawing and (y) the fifth anniversary of the Initial
Closing Date, the Policy Provider may, so long as a Policy Provider Default
shall not have occurred and be continuing, elect (a "Final Policy Election"),
upon at least four Business Days' prior written notice to the Drawing Agent
(with a copy to the Cash Manager and the Trustee), to pay on such Regular
Distribution Date, an amount sufficient (after giving effect to the application
of Available Collections in accordance with the applicable payment priorities
set forth in Section 3.08 hereof, the application of any Credit Facility
Drawings (or drawings under any Replacement Credit Facility) and the application
of any withdrawals from the Credit Facility Reserve Account and/or withdrawals
from the Senior Cash Collateral Account in accordance with the terms hereof) to
pay the then Pool Balance of the Certificates, plus accrued and unpaid interest
(at the Stated Rate of Interest for Certificates) thereon, for the period from
the immediately preceding Regular Distribution Date to such Regular Distribution
Date (any such amount to be paid by such Policy Provider, the "Outstanding
Balance"). Upon receipt of any such notice, the Cash Manager shall (a) calculate
the then Outstanding Balance for the Policy Provider and (b) prior to 12:00 p.m.
(New York City time) on the third Business Day prior to such Regular
Distribution Date, instruct the Drawing Agent to request, and the Drawing Agent
shall request no later than 12:00 p.m. (New York City time) on the second
Business Day prior to such Regular Distribution Date, a Policy Drawing from the
Policy Provider in the amount of the then Outstanding Balance (for payment into
the Certificate Account) for the Certificates. Upon receipt of any such request,
the Policy Provider or its fiscal agent shall, no later than 12:00 p.m. (New
York City time) on the later of (i) the applicable Regular Distribution Date and
(ii) the second Business Day following the Business Day on which such Policy
Provider receives the Drawing Agent's request referred to above, pay under the
Policy an amount equal to the Outstanding Balance. Upon receipt, the Pass
Through Trustee shall direct the

                                                                             103

payment of the amount in the Certificate Account to the holders of the
Certificates in payment of the Outstanding Balance therefor.

          (d) Final Policy Drawing. If the Cash Manager determines (calculated
as provided in Section 3.06(i)(iv)) that on the Legal Final Distribution Date of
the Certificates there will be insufficient funds available for the payment in
full of the Final Amount with respect to the Certificates as of such date, the
Cash Manager shall, prior to 12:00 p.m. (New York City time) on the third
Business Day prior to such Legal Final Distribution Date, instruct the Drawing
Agent to request, and the Drawing Agent shall, no later than 12:00 p.m. (New
York City time) on the second Business Day prior to such Legal Final
Distribution Date, request a Policy Drawing under the Policy (for payment into
the Certificate Account) in an amount sufficient to pay the Final Amount with
respect to the Certificates. Upon receipt of such request for a Policy Drawing,
the Policy Provider or its fiscal agent shall, no later than 12:00 p.m. (New
York City time) on the later of (i) such Legal Final Distribution Date and (ii)
the second Business Day following the Business Day on which the Policy Provider
receives the Drawing Agent's request referred to above, pay under and in
accordance with the terms of the Policy, an amount sufficient to pay the Final
Amount in respect of the Certificates. Any request received by the Policy
Provider after 12:00 p.m. (New York City time) on any Business Day shall be
deemed to have been received by the Policy Provider on the next Business Day.
Upon receipt, the Pass Through Trustee shall direct the payment of the amount in
the Certificate Account to the holders of the Certificates in payment of the
Final Amount therefor.

          (e) Avoidance Drawings. If at any time the Drawing Agent shall have
actual knowledge of the issuance of any Final Order, the Drawing Agent shall
promptly give notice thereof to the Trustee, the Guarantor Trustee, the Cash
Manager and the Policy Provider. The Cash Manager shall thereupon determine the
Avoided Payment with respect to the Certificates resulting therefrom and shall
promptly: (i) send to the Drawing Agent a Written Notice of such amount and (ii)
prior to the expiration of the Policy, instruct the Drawing Agent to, and the
Drawing Agent shall, deliver to the Policy Provider or its fiscal agent a Notice
of Avoided Payment under the Policy, together with a copy of the documentation
required by the Policy with respect thereto, requesting a Policy Drawing (each,
an "Avoidance Drawing") thereunder (for payment to the receiver, conservator,
debtor-in-possession, trustee in bankruptcy or the Drawing Agent (for deposit
into the Certificate Account), as applicable), in an amount equal to the amount
of the relevant Avoided Payment. To the extent that any portion of such
Avoidance Drawing is to be paid to the Drawing Agent such Written Notice shall
also set the date for the distribution of such portion of the proceeds of such
Policy Drawing which date shall constitute a Special Distribution Date and shall
be the third Business Day following the date of such Written Notice referred to
in clause (b) above. Upon receipt, the Drawing Agent shall pay the proceeds of
the specified Policy Drawing under the Policy to the Certificate Account and the
Pass Through Trustee shall direct the payment of such amount in the Certificate
Account to the holders of the Certificates.

          (f) Application of Policy Drawings. Notwithstanding anything to the
contrary contained in this Indenture, all payments received by the Drawing Agent
or the Pass Through Trustee in respect of a Policy Drawing (including, without
limitation, that portion, if any, of the proceeds of a Policy Drawing for any
Avoided Payment that is to be paid to the Drawing Agent

                                                                             104

and not to any receiver, conservator, debtor-in-possession or trustee in
bankruptcy as provided in the Policy) shall be promptly paid to the holders of
the Certificates.

          (g) Resubmission of a Notice of Payment. If the Policy Provider at any
time informs the Drawing Agent in accordance with the Policy that a Notice of
Nonpayment or Notice of Avoided Payment submitted by the Drawing Agent does not
satisfy the requirements of the Policy, the Drawing Agent shall, as promptly as
possible after being so informed, submit to the Policy Provider an amended and
revised Notice of Nonpayment or Notice of Avoided Payment, as the case may be,
and shall transfer to the Certificate Account the amount received pursuant to
such amended or revised Notice of Nonpayment or Notice of Avoided Payment when
received.

          (h) No Discharge of the Issuer's Obligations. Except to the extent
reimbursed to the Policy Provider, the payment on the Certificates with funds
drawn under the Policy shall not reduce the Outstanding Principal Balance of, or
interest due, on the ACS Group Class A Securities, or be deemed to discharge the
Issuer's obligation to repay such funds drawn under the Policy to the Policy
Provider, which obligation shall continue in full force and effect.

          (i) Interest Coverage. The interest payable by the Policy Provider
under the Policy shall include interest accruing during the pendency of any
bankruptcy, insolvency, receivership or other similar proceeding, regardless of
whether allowed or allowable in such proceeding.

          (j) Policy Provider Consent. The Policy Provider agrees that to the
extent its consent or approval (including with respect to any amendment) is
required under this Indenture or any other Related Document, such consent is not
required in the event that (x) a Policy Non-Consent Event has occurred or (y) in
the case of any consent required under Section 5.03, a Policy Provider Default
has occurred and is continuing. If the Policy Provider fails to provide any
party hereto with a written response with respect to any request for approval
(x) to perform maintenance or modifications to any Aircraft if such maintenance
or modification is required in connection with the remarketing of such Aircraft,
(y) to acquire a replacement Part or Engine by any ACS Group Member for purposes
of remarketing an Aircraft or (z) in connection with any action that would cause

therewith, within the time indicated by the Issuer or such Remarketing Servicer
in its proposal or, in any event, not less than fifteen Business Days after
receipt of such proposal (which proposal shall be in writing and contains a
legend stating that the Policy Provider's consent shall be deemed to have been
provided unless a response is received from the Policy Provider within fifteen
Business Days of receipt thereof) by the Policy Provider, the Policy Provider

with any such proposal, the Issuer or a Remarketing Servicer on its behalf has
promptly provided all information with respect to such proposal reasonably
requested by the Policy Provider. If the Issuer or the Remarketing Servicer has
not provided the Policy Provider with such requested information promptly then
the Policy Provider shall not be deemed to have consented to such proposal.

          (k) Release of Policy Provider. Notwithstanding anything to the
contrary herein, and for the avoidance of doubt, if the Policy is terminated and
surrendered to the Policy Provider

                                                                             105

     Section 3.15 Contributions. In the event that the amounts available for
distribution under Section 3.08 hereof and from any Eligible Credit Facility are
insufficient to pay in full any of the Secured Obligations or any other
Obligations, the Issuer or Guarantor may, out of funds provided to it by a
Holder of a Class E Security or a Shareholder (and not out of any amounts in the
Collections Account or any other Account or any other Collateral), pay such
shortfall with respect to such Obligations on the applicable Payment Date by
giving Written Notice of its intention to do so (specifying the amount thereof)
to the Cash Manager and the Trustee at least two Business Days prior to such
Payment Date by transferring funds in such amount (the "Contribution Amounts")
to the Trustee one Business Day prior to such Payment Date for deposit into the
applicable Account related to such Holder of a Class E Security or Shareholder,
as the case may be. All Contribution Amounts so deposited shall (a) be paid out
of such Account to the applicable Person or transferred to the applicable
Account notwithstanding Section 3.08 hereof, Article X hereof or anything else
to the contrary contained in this Indenture or the Security Trust Agreement and
(b) not constitute an obligation or debt of the Issuer.

     Section 3.16 DSCR Failure. In the event that the Cash Manager determines,
in accordance with Section 3.06(c) hereof, that a DSCR Failure for the related
Payment Date will occur, it shall provide Written Notice thereof (not later than
two Business Days prior to such Payment Date) to the Issuer, the Guarantor, the
Administrative Agent, the Trustees, the Pass Through Trustee, the Policy
Provider and the Rating Agencies. Following the occurrence of a DSCR Failure,
all proceeds on deposit in the Collections Account shall be applied in
accordance with Section 3.08(b) hereof.

under this Indenture to be true and correct or failure by the Issuer to comply
with any of the covenants, obligations, conditions or provisions binding on it
under this Indenture or any of the Securities (other than a payment default for
which provision is made in Section 4.01(a), (b) or (c) above), if such failure
or such breach materially adversely affects the Holders of such subclass of
Securities and continues for a period of 30 days (or, if such failure or breach
is capable of remedy within 90 days (or in the case of a breach or failure with
respect to a covenant contained in Section 5.03, 180 days) of the date of the
written notice referred to below and the Administrative Agent has promptly
provided the Trustee with a certificate stating that the Issuer has commenced,
or will promptly commence, and diligently pursue all reasonable efforts to

the Issuer or any ACS Ireland Subsidiary is diligently pursuing such remedy but
in any event no longer than 90 days (or 180 days, as applicable)) after written
notice thereof has been given to the Issuer by the Controlling Party or by the
Holders of at least a majority of the aggregate Outstanding Principal Balance of
the Securities of the Senior Class;

          (e) a court having jurisdiction in the premises enters a decree or

          (f) the Issuer or the Guarantor or any direct or indirect subsidiary
thereof (other than a Non-Significant Subsidiary) (i) commences a voluntary case
under any Applicable Law relating to bankruptcy, insolvency, receivership,
winding-up, liquidation, reorganization, Irish law examinership, relief of
debtors or other similar law now or hereafter in effect, or consents to the

                                                                             107

during which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect; provided, however, that any
such judgment or order shall not be an Event of Default under this Section
4.01(g) if and for so long as (i) the amount of such judgment or order is
covered by a valid and binding policy of insurance between the defendant and the
insurer covering payment thereof and (ii) such insurer, which shall be rated at
least "A" by A.M. Best Company or any similar successor entity, has been
notified of, and has not disputed the claim made for payment of, the amount of
such judgment or order;

          (h) the constitutional documents creating the Issuer or the Guarantor
cease to be in full force and effect without replacement documents having the
same terms being in full force and effect; or

          (i) an Event of Default (as defined in the Guarantor Indenture) has
occurred and is continuing under the Guarantor Indenture.

     Section 4.02 Acceleration, Rescission and Annulment. (a) If an Event of
Default with respect to the Senior Class (including the Class A-1 Securities so
long as any Class A-1 Securities are outstanding and the Policy Non-Consent
Event has not occurred) or any subclass thereof (other than an Event of Default
under Section 4.01(e) or (f) hereof) occurs and is continuing, the Controlling
Party may, and (if the Controlling Party is the Senior Trustee) upon the written
direction of Holders representing not less than a majority of the aggregate
Outstanding Principal Balance of the Senior Class shall give a Default Notice to
the Issuer, the Cash Manager, the Administrative Agent, the Security Trustee,
the Guarantor, the Trustee, the Guarantor Trustee, and the Pass Through Trustee
declaring the Outstanding Principal Balance of the Securities and all accrued
and unpaid interest thereon to be due and payable. If the Controlling Party is
the Policy Provider or the Initial Credit Facility Provider, only it may give a
Default Notice. Upon delivery of a Default Notice, such Outstanding Principal
Balance and all accrued and unpaid interest thereon shall be due and payable. At
any time after the Controlling Party has declared the Outstanding Principal
Balance of the Securities to be due and payable and prior to the exercise of any
other remedies pursuant to this Article IV, the Controlling Party may (and if
the Controlling Party is the Senior Trustee, upon the written direction of
Holders of a majority of the aggregate Outstanding Principal Balance of the
Senior Class shall) by Written Notice to the Issuer, the Senior Trustee (if not
the Controlling Party), the provider of any Eligible Credit Facility (if not the
Controlling Party), the Cash Manager, the Administrative Agent, the Security
Trustee and the Trustee, subject to Section 4.05(a) hereof, rescind and annul
such declaration and thereby annul its consequences if: (i) there has been paid
to or deposited with the Senior Trustee an amount sufficient to pay all overdue
installments of interest on the Securities, and the principal or Redemption
Price of the Securities that would have become due otherwise than by such
declaration of acceleration, (ii) the rescission or annulment would not conflict
with any judgment or decree and (iii) all other Defaults and Events of Default,
other than nonpayment of interest and principal on the Securities that have
become due solely because of such acceleration, have been cured or waived. If
the Controlling Party is the Policy Provider or the Initial Credit Facility
Provider, only it may give a notice of annulment. If an Event of Default under
Section 4.01(e) or (f) hereof occurs, the Outstanding Principal Balance of the
Securities and all accrued and unpaid interest thereon shall automatically
become due and payable without any further action by any party.

                                                                             108

          (b) Notwithstanding this Section 4.02 and Section 4.03 hereof, after
the occurrence and during the continuation of an Event of Default, no Holders of
any class of Securities other than the Senior Class may give or direct the
giving of a Default Notice or exercise or direct the exercise of any remedy in
respect of such Event of Default, and no Person other than the Controlling Party
may give a Default Notice or exercise any such remedy.

          (c) The Trustee shall provide each Rating Agency with a copy of any
Default Notice it receives pursuant to this Indenture.

          (d) Notwithstanding anything herein to the contrary, upon the delivery
of a Default Notice or if the Outstanding Principal Balance of the Securities
shall otherwise become due and payable pursuant to Section 4.02(a), if the net
assets of the Issuer available to be distributed to the Holders of the Class E
Securities under clause (xiii) of Section 3.08(c) are less than the outstanding
principal amount of the Class E Securities, then the outstanding principal
amount of the Class E Securities shall in the aggregate be deemed reduced to an
amount equal to such amount of net assets and the Holders of the Class E
Securities shall not have a claim for the difference between such amount of net
assets and the outstanding principal amount of the Class E Securities.

     Section 4.03 Other Remedies. If an Event of Default occurs and is
continuing, the Senior Trustee (at the direction of the Controlling Party if the
Senior Trustee is not the Controlling Party) may pursue any available remedy by
proceeding at law or in equity to collect the payment of principal or Redemption
Price of, or interest on, the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

     The Senior Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding.

     Section 4.04 Limitation on Suits. Without limiting the provisions of
Section 4.09 hereof and the final sentence of Section 13.04(a) hereof, no Holder
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, the Security Trust Agreement or the Securities, or
for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless:

          (a) the Senior Trustee is the Controlling Party;

          (b) such Holder holds Securities of the Senior Class and has
previously given written notice to the Senior Trustee of a continuing Event of
Default;

          (c) the Holders of a majority of the aggregate Outstanding Principal
Balance of the Senior Class make a written request to the Senior Trustee to
pursue a remedy hereunder;

          (d) such Holder or Holders offer to the Senior Trustee an indemnity
reasonably satisfactory to the Senior Trustee against any costs, expenses and
liabilities to be Incurred in complying with such request;

          (e) the Senior Trustee does not comply with such request within 60
days after receipt of the request and the offer of indemnity; and

                                                                             109

          (f) during such 60-day period, Holders of a majority of the
Outstanding Principal Balance of the Senior Class do not give the Senior Trustee
a revocation or direction inconsistent with such request.

          No one or more Holders may use this Indenture to affect, disturb or
prejudice the rights of another Holder or to obtain or seek to obtain any
preference or priority not otherwise created by this Indenture and the terms of
the Securities over any other Holder or to enforce any right under this
Indenture, except in the manner herein provided.

     Section 4.05 Waiver of Existing Defaults. (a) The Controlling Party or (if
the Controlling Party is the Senior Trustee) the Holders of a majority of the
Outstanding Principal Balance of the Senior Class by notice to the Senior
Trustee and the Issuer may waive any existing Default hereunder and its
consequences, except a Default: (i) in the deposit or distribution of any
payment required to be made on any Securities, (ii) in the payment of the
interest on, principal of or premium, if any, with respect to any Security or
(iii) in respect of a covenant or provision hereof which under Article IX hereof
cannot be modified or amended without the consent of the Holder of each Security
affected thereby, which (in the case of such Defaults described in clauses (i),
(ii) and (iii)) may not be waived. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture, but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon. Each such notice of waiver shall also be given to each Rating Agency.

          (b) Any written waiver of a Default or an Event of Default given by
the Controlling Party or the Holders to the Trustee and the Issuer in accordance
with the terms of this Indenture shall be binding upon the Trustee and the other
parties hereto. Unless such writing expressly provides to the contrary, any
waiver so granted shall extend only to the specific event or occurrence which
gave rise to the Default or Event of Default so waived and not to any other
similar event or occurrence which occurs subsequent to the date of such waiver.

     Section 4.06 Restoration of Rights and Remedies. If the Trustee or any
Holder of Securities of the Senior Class has instituted any proceeding to
enforce any right or remedy under this Indenture, and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or such Holder, then in every such case the Issuer, the Trustee and
the Holders shall, subject to any determination in such proceeding, be restored
severally and respectively to their former positions hereunder, and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding has been instituted.

     Section 4.07 Remedies Cumulative. Each and every right, power and remedy
herein given to the Trustee (or the Controlling Party) specifically or otherwise
in this Indenture shall be cumulative and shall be in addition to every other
right, power and remedy herein specifically given or now or hereafter existing
at law, in equity or by statute, and each and every right, power and remedy
whether specifically herein given or otherwise existing may be exercised from
time to time and as often and in such order as may be deemed expedient by the
Trustee (or the Controlling Party), and the exercise or the beginning of the
exercise of any power or remedy shall not be construed to be a waiver of the
right to exercise at the same time or thereafter any

                                                                             110

other right, power or remedy. No delay or omission by the Trustee (or the
Controlling Party) in the exercise of any right, remedy or power or in the
pursuance of any remedy shall impair any such right, power or remedy or be
construed to be a waiver of any Default on the part of the Issuer or to be an
acquiescence therein.

     Section 4.08 Authority of Courts Not Required. The parties hereto agree
that, to the greatest extent permitted by law, the Trustee shall not be obliged
or required to seek or obtain the authority of, or any judgment or order of, the
courts of any jurisdiction in order to exercise any of its rights, powers and
remedies under this Indenture, and the parties hereby waive any such requirement
to the greatest extent permitted by law.

     Section 4.09 Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal or Redemption Price of, or interest on its Security on or after the
respective due dates therefor expressed in such Security, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder.

     Section 4.10 Trustee May File Proofs of Claim. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and of any Holder allowed in any
judicial proceedings relating to any Issuer on the Securities, its creditors or
its property.

     Section 4.11 Undertaking for Costs. All parties to this Indenture agree,
and each Holder by its acceptance thereof shall be deemed to have agreed, that
in any suit for the enforcement of any right or remedy under this Indenture or
in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court in its discretion may require the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and the court in
its discretion may assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defense made by the party litigant. This Section
4.11 does not apply to a suit instituted by the Trustee, a suit instituted by
any Holder for the enforcement of the payment of principal or Redemption Price
of, or interest on its Security on or after the respective due dates expressed
in such Security, or a suit by a Holder or Holders of not less than a majority
of the Outstanding Principal Balance of any class or subclass of the Securities.

     Section 4.12 Control by Holders. Subject always to the provisions of this
Article IV, the Controlling Party shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee for such
class under this Indenture and other Related Documents; provided that, for such
class (a) such direction shall not be in conflict with any rule of law or with
this Indenture and would not involve the Trustee in personal liability or
expense; and (b) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

                                                                             111

or constitute a default under, the constitutional documents of the Issuer or the
constituent documents of any ACS Ireland Subsidiary or with any existing law,
rule or regulation applying to or affecting the Issuer or any ACS Ireland
Subsidiary or any judgment, order or decree of any government, governmental body

the Federal laws of the United States of America in force at the date hereof, it
is not necessary or desirable that this Indenture or any Related Document to

all Aircraft constituting the Initial Aircraft as of the Initial Closing Date

Aircraft on such Schedule will have such title to such Aircraft as was conveyed
to such Person, free and clear of all Liens created by or through such Person.

          (n) Aircraft Assets Related Documents. Each Aircraft Assets Related
Document is a legal, valid and binding agreement of the Person within the ACS

     Section 5.02 General Covenants. The Issuer covenants with the Trustee as
follows:

          (a) No Release of Obligations. The Issuer shall not take, or knowingly
permit any ACS Ireland Subsidiary to take, any action which would amend,
terminate (other than any termination in connection with the replacement of such
agreement with an agreement on terms substantially no less favorable to the ACS
Ireland Group than the agreement being terminated) or discharge or prejudice the
validity or effectiveness of this Indenture (other than as permitted herein),
the Security Trust Agreement, the Purchase Agreement, the Cash Management
Agreement, any organizational document of the Issuer or any ACS Ireland
Subsidiary (unless such ACS Ireland Subsidiary no longer holds any direct or
indirect interest in an Aircraft or a Lease), the Policy (other than as
expressly permitted hereunder), the Initial Credit Facility (other than as
expressly permitted hereunder), the Irish Remarketing Services Agreement, the
Back-Up Remarketing Services Agreement, the Administrative Agency Agreement or
the Hedge Overview Services Agreement or any other Related Document to which the
Issuer or any ACS Ireland Subsidiary (unless such ACS Ireland Subsidiary no
longer holds any interest in an Aircraft or a Lease) is a party or permit any
other party (other than an ACS Group Member) to any such document to be released
from such obligations, except, in each case, as permitted or contemplated by the
terms of such document and except that in no event shall the Policy be so
terminated (other than as expressly permitted hereunder), and provided that such
actions may be taken or permitted and such releases may be permitted (other than
with respect to the termination

                                                                             114

of the Policy) if the Issuer shall have first obtained a Board Resolution
determining that such action, permitted action or release does not materially
adversely affect the interests of the Holders of the Securities, the Policy
Provider or the Initial Credit Facility Provider and having given notice thereof
to the Rating Agencies and the prior written consent of the Policy Provider and
the Initial Credit Facility Provider has been obtained; and provided further
that, in any case (i) the Issuer shall not take any action which would result in
any amendment or modification to the conflicts standard or duty of care in such
agreements, (ii) except in the circumstances expressly contemplated in this
Indenture, the Issuer may not amend the Policy without the unanimous consent of
the Holders of the Covered Class A Securities and without obtaining a Rating
Agency Confirmation and (iii) there must be at all times an administrative agent
with respect to the ACS Group Services (as defined in the Administrative Agency
Agreement) and a remarketing servicer with respect to all ACS Group Aircraft.

          (b) Limitation on Encumbrances. The Issuer shall not, and shall not
permit any ACS Ireland Subsidiary to, create, Incur, assume or suffer to exist
any mortgage, pledge, lien, encumbrance, charge or security interest (in each
case, an "Encumbrance"), including, without limitation, any conditional sale,
any sale with recourse against any ACS Ireland Subsidiary or any Affiliate of
any ACS Ireland Subsidiary, or any agreement to give any security interest over
or with respect to any of the Issuer's or any ACS Ireland Subsidiary's assets
(other than the segregation of the Segregated Funds) including, without
limitation, all shares of capital stock, all beneficial interests in trusts, all
ordinary shares and preferred shares and any options, warrants and other rights
to acquire such shares or beneficial interests ("Ownership Interest") and any
Indebtedness of any ACS Ireland Subsidiary held by the Issuer or any ACS Ireland
Subsidiary.

          Notwithstanding the foregoing, the Issuer may create, Incur, assume or
suffer to exist (i) any Permitted Encumbrance, (ii) any security interest
created or required to be created under the Security Documents, (iii)
Encumbrances over rights in or derived from Leases, upon prior written consent
of the Policy Provider and receipt of a Rating Agency Confirmation (provided
that any transaction or series of transactions resulting in such Encumbrance,
taken as a whole, does not materially adversely affect the amount of Collections
that would have been received by the Issuer and any other ACS Ireland Group
Member from such Lease had such Encumbrance not been created), (iv) any other
Encumbrance the validity or applicability of which is being contested in good
faith in appropriate proceedings by the Issuer or any ACS Ireland Subsidiary,
(v) any Encumbrance in connection with any transfer of title to or Lease of
Aircraft (A) to or in favor of a trust or an entity (which, in either case, is
not an ACS Group Member) for the purpose of registering the Aircraft under the
laws of an applicable jurisdiction so long as, however, the Issuer or any ACS
Ireland Subsidiary retains the beneficial or economic ownership of the Aircraft
or (B) from such trust or entity to the Issuer or an ACS Ireland Subsidiary
(subject in the case of this subclause (v) to the limitations set forth in
subclause (vi) of Section 5.02(g) below), and (vi) any lien created in favor of
the issuer of a surety bond, letter of credit or similar instrument to be
obtained by the Issuer or any ACS Ireland Subsidiary in connection with the
repossession of an Aircraft or other enforcement action under a Lease.

          For purposes of this Indenture, "Affiliate" means, with respect to any
Person, any other Person that, directly or indirectly, Controls, is Controlled
by or is under common control with, such Person or is a director or officer of
such Person; "Control" of a Person means the possession, direct or indirect, of
the power to direct or cause the direction of the management and

                                                                             115

policies of such Person, whether through the ownership of voting Ownership
Interest, by contract or otherwise. For the avoidance of doubt, each ACS Group
Member shall be an "Affiliate" of each other ACS Group Member. For the purposes
of this Indenture, "Permitted Encumbrance" means (i) any lien for Taxes not yet
due and payable or which are being contested in good faith by appropriate
proceedings; (ii) in respect of any Aircraft, any lien of a repairer, carrier or
hangar keeper arising in the ordinary course of business by operation of law or
any engine or parts-pooling arrangements or other similar lien; (iii) any

under any Lease thereof (other than liens or encumbrances created by the
relevant lessor); (iv) any lien created by or through or arising from debt or
liabilities or any act or omission of any Lessee in each case either in
contravention of the relevant Lease (whether or not such Lease has been
terminated) or without the consent of the relevant lessor (provided that if such
lessor becomes aware of any such lien, it shall use commercially reasonable
efforts to have any such lien lifted); (v) any head lease, lease, conditional
sale agreement or Purchase Option under the Initial Lease of any Initial
Aircraft existing on the date of acquisition of such Aircraft or otherwise
existing on the relevant Closing Date or Aircraft Agreement meeting the
requirements of clause (iii) or (v) of the second paragraph of Section 5.02(g)
hereof; (vi) any lien for air navigation authority, airport tending, gate or
handling (or similar) charges or levies; (vii) any lien created in favor of the
Issuer, any ACS Ireland Subsidiary or the Security Trustee; (viii) any
Encumbrance arising under an Eligible Credit Facility or a Conversion Agreement;
and (ix) any other lien not referred to in clauses (i) through (viii) of this
paragraph which would not adversely affect the owner's rights provided that the
amount secured by liens under this clause (ix) does not exceed, individually,
$250,000 per Aircraft or, in the aggregate, 0.25% of the Initial Appraised Value
of the ACS Group Portfolio.

          (c) Limitation on Restricted Payments. The Issuer shall not, and shall
not permit any ACS Ireland Subsidiary to (i) purchase, redeem, retire or
otherwise acquire for value any shares of Ownership Interest in the Issuer, the
Guarantor, any ACS Ireland Subsidiary or ACS Bermuda Subsidiary held by or on
behalf of Persons other than the Issuer or any ACS Ireland Subsidiary or other
ACS Group Member other than as provided in Sections 2.12 and 5.02(l)(ii)(B)
hereof; (ii) make any payment of principal, interest or premium, if any, on the
Securities or make any voluntary or optional repurchase, defeasance or other
acquisition or retirement for value of Indebtedness of the Issuer or such ACS
Ireland Subsidiary that is not owed to the Issuer, the Guarantor, such ACS
Ireland Subsidiary or such ACS Bermuda Subsidiary or other ACS Group Member
other than in accordance with Articles II, III and XII hereof, the Policy
Provider Documents and otherwise provided for in the Related Documents; provided
that the Issuer or any of its Affiliates may repurchase, defease or otherwise
acquire or retire any of the Securities other than from the Available
Collections so long as any new notes of the Issuer issued in connection with
such transaction rank pari passu with the Securities being repurchased,
defeased, acquired or retired and the Board shall determine that such action
does not materially adversely affect the Holders and shall have obtained prior
written consent of the Policy Provider and a Rating Agency Confirmation with
respect thereto or (iii) make any Investments (other than Permitted Account
Investments, Allowed Restructurings, Investments permitted under Section 5.02(e)
hereof and Investments in any ACS Ireland Group Member and any other ACS Group
Member pursuant to the Purchase Agreement or a Permitted Additional Aircraft
Acquisition; provided that written notification of the organization or
acquisition of each

                                                                             116

such ACS Ireland Group Member shall have been given to the Policy Provider and
the Initial Credit Facility Provider).

          The term "Investment" for purposes of the above restriction means any
loan or advance to a Person, any purchase or other acquisition of any beneficial
interest, capital stock, warrants, rights, options, obligations or other
securities of such Person, any contribution to such Person or any other
Investment in such Person. For the avoidance of doubt, "Investment" shall not
include any obligation of a purchaser of an Aircraft to make deferred or
installment payments pursuant to any Aircraft Agreement specified in (iii) or
(v) of the second paragraph of Section 5.02(g) hereof so long as the ACS Ireland
Group retains a security interest in the relevant Aircraft until all such
obligations are discharged and shall not include any payment owing to a Lessee.

          (d) Limitation on Restrictions on Dividends and Other Payments. The
Issuer shall not, and shall not permit any ACS Ireland Subsidiary to, create or
otherwise suffer to exist any consensual encumbrance or restriction of any kind
on the ability of any ACS Ireland Subsidiary to (i) declare or pay dividends or
make any other distributions permitted by Applicable Law, or purchase, redeem or
otherwise acquire for value, the Ownership Interest of the Issuer or such ACS
Ireland Subsidiary, as the case may be; (ii) pay any Indebtedness owed to the
Issuer or such ACS Ireland Subsidiary; (iii) make loans or advances to the
Issuer or such ACS Ireland Subsidiary; or (iv) transfer any of its property or
assets to the Issuer or any other ACS Ireland Subsidiary.

          The foregoing provisions shall not restrict any consensual
encumbrances or other restrictions: (i) existing on the Initial Closing Date or,
in the case of any Aircraft, the Acquisition Date of such Aircraft, under any
Related Document, and any amendments, extensions, refinancings, renewals or
replacements of such documents; provided that such consensual encumbrances and
restrictions in any such amendments, extensions, refinancings, renewals or
replacements are no less favorable in any material respect to the Holders than
those previously in effect and being amended, extended, refinanced, renewed or
replaced; or (ii) in the case of clause (iv) of the preceding paragraph, that
restrict in a customary manner the subletting, assignment or transfer of any
property or asset that is a lease, license, conveyance or contract or similar
property or asset.

     respective Affiliates in the ordinary course of business (an "Allowed
     Restructuring");

          (ii) providing loans to, guaranteeing or otherwise supporting the
     obligations and liabilities of any ACS Ireland Group Member or any ACS
     Bermuda Group Member, in each case whether or not the Issuer or any ACS
     Ireland Subsidiary derives a benefit therefrom so long as such loans,
     guarantees or other supports are provided in connection with the purposes
     set forth in clause (i) of this Section 5.02(e); provided that written
     notification shall have been given to each Rating Agency, the Policy
     Provider and the Initial Credit Facility Provider of such loan, guarantee
     or other support; provided that, no such notice shall be required for any
     guarantee provided by an ACS Ireland Group Member with respect to any

     any applicable ACS

                                                                             118

Indebtedness or other obligation of any other Person and, without limiting the
generality of the foregoing, any obligation, direct or indirect, contingent or
otherwise, of such Person (i) to purchase or pay (or advance or supply funds for
the purchase or payment of) such Indebtedness or other obligation of such other
Person or (ii) entered into for purposes of assuring in any other manner the
obligee of such Indebtedness or other obligation of the payment thereof or to
protect such obligee against loss in respect thereof (in whole or in part);
provided that the term "guarantee" shall not include endorsements for collection
or deposit in the ordinary course of business. The term "guarantee" when used as
a verb has a corresponding meaning.

          (g) Limitation on Aircraft Dispositions. The Issuer shall not, and
shall not permit any ACS Ireland Subsidiary to, sell, transfer or otherwise
dispose of any Aircraft or any interest therein other than as provided in the

acquired, (b) any Engine or Part in connection with the replacement of such
Engine or Part in accordance with a Lease or (c) one or more Aircraft or an

Ireland Subsidiaries and other ACS Group Members without limitation, and among
the Issuer and/or any other ACS Ireland Group Member and any other ACS Group
Member provided that no such sale, transferor or other disposition shall be made
if such sale, transfer or disposition would materially adversely affect the
Holders or the Policy Provider as confirmed by a certification of the Issuer;
provided further that written notification shall have been given to each Rating
Agency and the Policy Provider of such sale, transfer or disposition, (iii)
pursuant to any Aircraft Agreement (including a Purchase Option); provided that
such sale does not result in a Concentration Default and the net present value

shall not exceed four for all of the ACS Group Members without the prior written
consent of the Policy Provider, (iv) pursuant to receipt of insurance proceeds
in connection with an event of loss, (v) pursuant to an Aircraft Agreement the
net present value of the cash Net Sale Proceeds is less than 107% of the Note
Target Price, provided that (with respect to this clause (v)), (x) in any one
calendar year such sales do not exceed 10% of the Assumed Portfolio Value as of
the first day of such calendar year of the ACS Group Portfolio as a whole for

obtained and (z) such sale, transfer or disposition would not materially
adversely affect the Holders or Policy Provider as confirmed by a certificate of
the Issuer, or (vi) in connection with a transfer of title or another

                                                                             121

interest in an Aircraft (A) to or in favor of a trust or another entity which,
in either case, is not an ACS Group Member for the purposes of registering the
Aircraft under the laws of an applicable jurisdiction where the Issuer or an ACS
Ireland Subsidiary retains the beneficial or economic ownership of the Aircraft
or (B) from such trust or entity to the Issuer or an ACS Ireland Subsidiary,
except that without the consent of the Policy Provider at any time not more than
two Aircraft may be subject to the arrangements described in this subclause (vi)
and subclause (v) of the second paragraph of Section 5.02(b) hereof.

          For the purpose of this Section 5.02(g), the net present value of the
cash Net Sale Proceeds of any sale, transfer or other disposition of any
Aircraft means the present value of all payments received or to be received by
the Issuer or any ACS Ireland Subsidiary from the date of execution or option
granting date, as the case may be, of the relevant Aircraft Agreement through
and including the date of transfer of title to such Aircraft, discounted back to
the date of execution or option granting date, as the case may be, of such
Aircraft Agreement at the weighted average cost of funds of the Issuer (based on
the cost of funds represented by the Securities (excluding any payments on the
Class E Securities) and taking into account any Hedge Agreements).

          (h) Limitation on Aircraft Acquisitions. The Issuer shall not, and
shall not permit any ACS Ireland Subsidiary to, purchase or otherwise acquire
any Aircraft other than the Initial Aircraft or any interest therein.

          Notwithstanding the foregoing, the Issuer may, and may permit any ACS
Ireland Subsidiary to, (A) purchase or otherwise acquire, directly or
indirectly, Additional Aircraft from time to time (a "Permitted Additional

extent that the Issuer or such ACS Ireland Subsidiary delivers to the Trustee,
the Initial Credit Facility Provider and the Policy Provider an Opinion of
Counsel reasonably acceptable to the Trustee, the Initial Credit Facility
Provider and the Policy Provider providing that such policy or procedure is no
longer necessary, due to a change in law or otherwise, for the rendering of such
earlier opinion relating to the issue of substantive consolidation and (B) a

individuals on each board of directors;

          (D) except with respect to any U.S. Trust, cause its board of
directors to meet at least quarterly or act pursuant to written consent and keep
minutes of such meetings and actions and observe all other corporate and other

the case may be, consistently and in furtherance of the foregoing and in
compliance with applicable law.

          (r) Independent Director. The Issuer shall cause each ACS Ireland

     Section 5.03 Operating Covenants. The Issuer covenants with the Trustee as
follows:

          (a) Concentration Limits. Without receipt of a Rating Agency
Confirmation from Moody's and the prior written consent of the Policy Provider,
the Issuer shall not permit any ACS Ireland Subsidiary to lease or re-lease any
Aircraft if entering into such proposed Lease would cause the ACS Group
Portfolio to exceed any of the Concentration Limits set forth in Exhibit C
hereto (as such limits may be adjusted by the Issuer from time to time, subject
to receipt of a Rating Agency Confirmation and the prior written consent of the
Policy Provider, the "Concentration Limits"); provided that the Issuer or any
ACS Ireland Subsidiary shall be entitled to renew or extend any Lease to the
existing Lessee thereunder irrespective of the effect of such renewal or
extension on the Concentration Limits with the prior written consent of the
Policy Provider. The Issuer shall not, and shall not permit any ACS Ireland
Subsidiary to, (i) lease (including any renewal or extension of any existing
Lease) any Aircraft to any Lessee habitually based or domiciled in any of the
jurisdictions set forth as "Prohibited" in the last section of the Concentration
Limits as set forth on Exhibit C hereto and as amended from time to time upon
the receipt of a Rating Agency Confirmation and the prior written consent of the
Policy Provider (each such jurisdiction, a "Prohibited Country"), (ii) enter
into any Lease (including any renewal or extension of any existing Lease) that
expressly permits the Lessee to sublease an Aircraft to a sublessee habitually
based or domiciled in a Prohibited Country, or (iii) consent to a sublease of an
Aircraft to a sublessee habitually based or domiciled in a Prohibited Country.

          (b) Compliance with Law, Maintenance of Permits. The Issuer shall (i)
comply, and cause each ACS Ireland Subsidiary to comply, in all material
respects with all Applicable

                                                                             128

Laws, (ii) obtain, and cause each ACS Ireland Subsidiary to obtain, all material
governmental (including regulatory) registrations, certificates, licenses,
permits and authorizations required for the use and operation of the Aircraft
owned by it, including, without limitation, a current certificate of
airworthiness for each such Aircraft (issued by the Applicable Aviation
Authority and in the appropriate category for the nature of the operations of
such Aircraft), except that (A) no certificate of airworthiness shall be
required for any Aircraft (x) during any period when such Aircraft is undergoing
maintenance, modification or repair, (y) following the withdrawal or suspension
by such Applicable Aviation Authority of certificates of airworthiness in
respect of all aircraft of the same model or period of manufacture as such
Aircraft (in which case the Issuer shall comply, and cause each ACS Ireland
Subsidiary to comply, with all directions of such Applicable Aviation Authority
in connection with such withdrawal or suspension), (B) no registrations,
certificates, licenses, permits or authorizations required for the use or
operation of any Aircraft need be obtained with respect to any period when such
Aircraft is not being operated and (C) no such registrations, certificates,
licenses, permits or authorizations shall be required to be maintained for any
Aircraft that is not the subject of a Lease, except to the extent required under
Applicable Laws, (iii) not cause or knowingly permit, directly or indirectly,
through any ACS Ireland Subsidiary, any Lessee to operate any Aircraft under any
Lease in any material respect contrary to any Applicable Law and (iv) not
knowingly permit, directly or indirectly, through any ACS Ireland Subsidiary,
any Lessee not to obtain all material governmental (including regulatory)
registrations, certificates, licenses, permits and authorizations required for
such Lessee's use and operation of any Aircraft under any operating Lease except
as provided, mutatis mutandis, in clauses (ii)(A) and (ii)(B) above.

          Notwithstanding the foregoing, no breach of this Section 5.03(b) shall
be deemed to have occurred by virtue of any act or omission of a Lessee or
sub-lessee, or of any Person which has possession of the Aircraft or any Engine
for the purpose of repairs, maintenance, modification or storage, or by virtue
of any requisition, seizure, or confiscation of the Aircraft (other than seizure
or confiscation arising from a breach by the Issuer or an ACS Ireland Subsidiary
of this Section 5.03(b)) (each, a "Third Party Event"); provided that (i)
neither the Issuer nor any ACS Ireland Subsidiary consents or has consented to
such Third Party Event; and (ii) the Issuer or ACS Ireland Subsidiary which is
the lessor or owner of such Aircraft promptly and diligently takes such
commercially reasonable actions as any leading international aircraft operating
lessor would reasonably take in respect of such Third Party Event, including, as
deemed appropriate (taking into account, inter alia, the laws of the
jurisdictions in which the Aircraft are located), seeking to compel such Lessee
or other relevant Person to remedy such Third Party Event or seeking to
repossess the relevant Aircraft or Engine.

          (c) Maintenance of Assets. The Issuer shall (i) with respect to each
Aircraft and Engine that is subject to a Lease, cause, directly or indirectly,
through any ACS Ireland Subsidiary, such Aircraft and Engine to be maintained in
a state of repair and condition consistent with the reasonable commercial
practice of any leading international aircraft operating lessor with respect to
similar aircraft under lease, taking into consideration, among other things, the
identity of the relevant Lessee (including the credit standing and operating
experience thereof), the age and condition of the Aircraft and the jurisdiction
in which such Aircraft will be operated or registered under such Lease and (ii)
with respect to each Aircraft that is not subject to a Lease, maintain, and
cause each ACS Ireland Subsidiary to maintain, such Aircraft in a state of
repair and condition consistent with the reasonable commercial practice of any
leading

                                                                             129

international aircraft operating lessor with respect to aircraft not under
lease. Notwithstanding the foregoing, no breach of this Section 5.03(c) shall be
deemed to have occurred by virtue of any Third Party Event; provided that (i)
neither the Issuer nor any ACS Ireland Subsidiary consents or has consented to
such Third Party Event; and (ii) the Issuer or such ACS Ireland Subsidiary which
is the lessor or owner of such Aircraft promptly and diligently takes such
commercially reasonable actions as any leading international aircraft operating
lessor would reasonably take in respect of such Third Party Event, including as
deemed appropriate, seeking to compel such Lessee or other relevant Person to
remedy such Third Party Event or seeking to repossess the relevant Aircraft or
Engine.

          (d) Notification of Trustee, Holders, Policy Provider, Initial Credit
Facility Provider, Administrative Agent and Cash Manager. The Issuer shall
notify the Trustee, the Holders, the Policy Provider, the Initial Credit
Facility Provider, the Administrative Agent and the Cash Manager in writing as
soon as the Issuer or any ACS Ireland Subsidiary becomes aware of any loss,
theft, damage, confiscation, requisition or destruction to any Initial Aircraft,
Additional Aircraft or Engine if the potential cost of repair or replacement of
such asset (without regard to any insurance claim related thereto) may exceed
the greater of $2,000,000 and the damage notification threshold contained in the
applicable Lease.

          (e) Leases. The Issuer shall adopt and shall cause the Irish
Remarketing Servicer to utilize the pro forma lease in the form provided to the
Issuer on the Initial Closing Date (or, with respect to the Back-Up Remarketing
Servicer, the "Commencement Date" as defined in the Back-Up Remarketing Services
Agreement) as such pro forma lease agreement or agreements may be revised for
purposes of the ACS Ireland Group specifically or generally from time to time by
the Irish Remarketing Servicer (the "Irish Remarketing Servicer's Pro Forma
Lease") in a manner consistent with the Irish Remarketing Servicer's "Standard
of Care" and the Irish Remarketing Servicer's "Conflicts Standard" (as each term
is defined in the Irish Remarketing Services Agreement), for use by the Irish
Remarketing Servicer on behalf of the Issuer, any ACS Ireland Subsidiary as a
starting point in the negotiation of Future Leases with Persons who are not ACS
Ireland Group Members; provided, however, that with respect to any Future Lease
entered into in connection with (x) the renewal or extension of an Initial
Lease, (y) the leasing of an Aircraft to a Person that is or was a Lessee under
an Initial Lease or (z) the leasing of an Aircraft to a Person that is or was
the lessee under an operating lease of an aircraft that is being managed or
serviced by the Irish Remarketing Servicer (such Future Lease, a "Renewal
Lease"), a form of lease substantially similar to such Initial Lease or
operating lease (a "Precedent Lease"), as the case may be, may be used by the
Irish Remarketing Servicer in lieu of the Irish Remarketing Servicer's Pro Forma
Lease on behalf of the Issuer or any ACS Ireland Subsidiary as a starting point
in the negotiation of such Future Lease with Persons who are not ACS Ireland
Group Members and provided further, however, that if the Board determines, in an
annual review of the Irish Remarketing Servicer's Pro Forma Lease on or before
each anniversary of the relevant Closing Date, that any revision to the Irish
Remarketing Servicer's Pro Forma Lease made from time to time since the
preceding review by the Board (or, with respect to the first anniversary of the
Initial Closing Date, since the Initial Closing Date) is substantially
inconsistent with the core lease provisions of the Issuer set forth in Exhibit F
to this Indenture (as such provisions may be amended from time to time, the
"Core Lease Provisions") in a manner and to such a degree as to have a material
adverse effect on the Holders, taking into consideration, inter alia, such
revision and any risk that the Aircraft might not be able to be

                                                                             130

leased on terms consistent with the provisions of the Irish Remarketing
Servicer's Pro Forma Lease without such revisions, then the Board shall direct
the Irish Remarketing Servicer not to include such revision in the Irish
Remarketing Servicer's Pro Forma Lease to be used thereafter as the starting
point in the negotiation of any Future Lease with respect to the Aircraft. If
the Board determines that any such revision to the Irish Remarketing Servicer's
Pro Forma Lease will not have a material adverse effect on the Holders, then the
Board shall (i) amend the applicable Core Lease Provisions to incorporate such
revisions (ii) notify the Rating Agencies, the Policy Provider and the Initial
Credit Facility Provider of any Future Lease entered into the terms of which are
materially less favorable from the point of view of the lessor than any of the
Leases then in effect, including without limitation, such changes to the Core
Lease Provisions; provided that the Core Lease Provisions may not be amended
without the prior written consent of the Policy Provider.

          The Issuer shall not enter into, and shall not permit any ACS Ireland
Subsidiary to enter into, any Future Lease the Rental Payments under which are
denominated in a currency other than U.S. dollars unless the Issuer receives a
Rating Agency Confirmation and the prior written consent of the Policy Provider;
provided, that the Issuer may enter any Future Lease the Rental Payments under
which are denominated in euros if (a) the sum of the Assumed Base Values as of
the Payment Date immediately preceding any date of determination of each ACS
Group Aircraft subject to leases the Rental Payments under which are denominated
in euros does not exceed 5% of the sum of the Assumed Base Values as of such
Payment Date of all ACS Group Aircraft and (b) the currency exposure is hedged
in accordance with the Issuer's hedging policy.

          (f) Opinions. The Issuer shall not enter into, and shall not permit
any ACS Ireland Subsidiary to enter into, any Future Lease with any Person that
is not an ACS Ireland Group Member or change the jurisdiction of registration of
any Aircraft that is subject to a Lease, unless, upon entering into such Future
Lease or changing the jurisdiction or registration of such Aircraft (or within a
commercially reasonable period thereafter), the Irish Remarketing Servicer
obtains such legal opinions, if any, with regard to compliance with the
registration requirements of the relevant jurisdiction, enforceability of the
Future Lease and such other matters customary for such transactions to the
extent that receiving such legal opinions is consistent with the reasonable
commercial practice of any leading international aircraft operating lessor.

          (g) Insurance. The Issuer shall maintain or cause, directly or
indirectly through the ACS Ireland Subsidiaries, to be maintained with reputable
and responsible insurers or, provided that the applicable reinsurance policy
contains a cut-through clause requiring the reinsurers to pay the insured
directly (other than in any instances where local law requirements mandate
otherwise), with reputable and responsible insurers that maintain relevant
reinsurance with reputable and responsible reinsurers (i) airline hull insurance
for each Aircraft in an amount at least equal to the Note Target Price for such
Aircraft (or the equivalent thereof from time to time if such insurance is
denominated in a currency other than U.S. dollars) and (ii) airline liability
insurance for each Aircraft and occurrence in an amount at least equal to the
relevant amount set forth on Exhibit D hereto for each model of aircraft and as
amended from time to time pursuant to the receipt of a Rating Agency
Confirmation from Standard & Poor's and prior written notice of such amendment
is provided to Moody's and the prior written consent of the Policy Provider and
(iii) airline repossession insurance ("Repossession Insurance") for each
Aircraft subject to a Lease to a Lessee habitually based in a jurisdiction set
forth under the "Repossession Guidelines" set forth in Exhibit C hereto, which
may be amended from time to time only pursuant to the receipt of a Rating Agency
Confirmation and the prior written consent of the

                                                                             131

Policy Provider, in an amount at least equal to the Note Target Price (or the
equivalent thereof from time to time if such insurance is denominated in a
currency other than U.S. dollars) for such Aircraft; provided, however, that
with respect to any such insurance for any Aircraft subject to a Lease, such
insurance may be subject to commercially reasonable deductible and
self-insurance arrangements and may take into account any customary reductions
in limits for Aircraft in storage and not in operation (in each case taking into
account, inter alia, the creditworthiness and experience of the Lessee, if any,
the type of aircraft and market practices in the aircraft insurance industry
generally). The coverage and terms (including endorsements, deductibles and
self-insurance arrangements) of any insurance maintained with respect to any
Aircraft not subject to a Lease shall be substantially consistent with the
reasonable commercial practices of any leading international aircraft operating
lessor regarding similar aircraft.

          In determining the amount of insurance required to be maintained by
this Section 5.03(g), the Issuer may take into account any indemnification from,
or insurance provided by, any governmental, supranational or inter-governmental
authority or agency (other than, with respect to Repossession Insurance, any
governmental authority or agency of any jurisdiction for which Repossession
Insurance must be obtained), the sovereign foreign currency debt of which is
rated at least AA, or the equivalent, by at least one of the Rating Agencies,
against any risk with respect to an Aircraft at least in an amount which, when
added to the amount of insurance against such risk maintained by the Issuer (or
which the Issuer has caused to be maintained), shall be at least equal to the
amount of insurance against such risk otherwise required by this Section 5.03(g)
(taking into account self-insurance permitted by this Section 5.03(g)). Any such
indemnification or insurance provided by such government shall provide
substantially similar protection as the insurance required by this Section
5.03(g).

          The Issuer shall cause, or shall cause the applicable ACS Group
Subsidiary to cause, each Lessee to be obligated under its respective Lease to
maintain War Risk Coverage as part of the insurance requirements in such Lease.
The Issuer shall cause, or shall cause the applicable ACS Group Subsidiary to
cause, each Lessee to maintain War Risk Coverage in accordance with the
requirements set forth in Exhibit D hereto. In the event that a Lessee does not
maintain such requisite level of War Risk Coverage or allows such War Risk
Coverage to lapse, the Issuer shall cause the applicable ACS Group Subsidiary
lessor to immediately bring enforcement proceedings against the applicable
Lessee under the terms of the applicable Lease to repossess the applicable
Aircraft and use commercially reasonable efforts of a leading international
aircraft operating lessor to ensure that such Aircraft does not operate without
War Risk Coverage at such required levels; provided, however, that so long as
the Issuer is in compliance with the requirements set forth in the next
succeeding sentence and the applicable Lessee is not otherwise in default under
the related Lease, the Issuer shall have 180 days to cause, or to cause the
applicable ACS Group Subsidiary lessor to cause, the Lessee to comply with the
insurance requirements set forth herein and under the Lease prior to bringing
any such enforcement proceedings; provided further that if, for any reason,
neither the Issuer nor the applicable ACS Group Subsidiary lessor has a right
under the applicable Lease to require a Lessee to maintain War Risk Coverage at
the requisite levels, the Issuer shall nevertheless be

                                                                             132

obligated to cause such Lessee to maintain War Risk Coverage at the requisite
levels described in Exhibit D hereto (by negotiating in good faith with such
Lessee or otherwise) or shall otherwise cause War Risk Coverage to be maintained
at the requisite levels described in Exhibit D hereto, subject only to the
additional time provided in the immediately preceding proviso if the Issuer is
in compliance with requirements set forth in the next succeeding sentence and
the applicable Lessee is not otherwise in default under the related Lease. The
Issuer shall carry contingent and excess War Risk Coverage in accordance with
the requirements set forth in Exhibit D hereto.

          The obligations set forth in the foregoing paragraph shall be waived
if (a) prior written notice shall be provided to the Rating Agencies and (b) the
Policy Provider shall have provided a written consent to such waiver.

          (h) Indemnity. The Issuer shall, and shall cause each ACS Ireland
Subsidiary to, include in each Lease between the Issuer or such ACS Ireland
Subsidiary and a Person who is not an ACS Ireland Group Member an indemnity from
such Person in respect of any losses or liabilities arising from the use or
operation of the Aircraft during the term of such Lease, subject to such
exceptions, limitations and qualifications as are consistent with the reasonable
commercial practice of any leading international aircraft operating lessor.

          (i) Appraisal of Aircraft. The Issuer shall, within 90 days after the
Expected Final Payment Date of the ACS Group Subclass A-1 Securities, deliver to
the Trustee, the Policy Provider and the Rating Agencies three appraisals of the
Base Value of each of the Aircraft from each of Initial Appraisers or, if any of
the Initial Appraisers is unable to provide an appraisal, from the remaining
Initial Appraisers and such other Appraisers selected by the Issuer, each such
appraisal to be dated within 30 days prior to its delivery to the Trustee, the
Policy Provider and the Rating Agencies.

     Section 5.04 Compliance Through Agents. The Issuer shall be entitled to
delegate the performance of any of its covenants hereunder to one or more
Service Providers pursuant to one or more Related Documents entered into in
accordance with the terms of this Indenture so long as each such Related
Document is subject to the Lien of the Security Trust Agreement. Nothing in this
Section 5.04 is intended to, or shall, relieve the Issuer from any liability or
consequences hereunder arising from the failure of the Issuer or any such
Service Provider to perform any such covenant strictly in accordance with the
terms of this Indenture.

                                   ARTICLE VI

                                   THE TRUSTEE

responsibilities of the Trustee shall be as provided by the TIA and as set forth
herein and in the Guarantor Indenture. The Trustee accepts the trusts hereby
created and applicable to it and agrees to perform the same but only upon the

receive and disburse all moneys received by it in accordance with the terms
hereof and in the Guarantor Indenture. The Trustee in its individual capacity
shall not be answerable or accountable under any circumstances, except for its
own willful misconduct or negligence or

                                                                             133

breach of any of its representations or warranties set forth herein and the

other parties to any of the Related Documents. The fees and out-of-pocket
expenses of the Trustee shall be Expenses of the Issuer.

     Section 6.02 Absence of Duties. Except in accordance with written
instructions or requests furnished hereunder, the Trustee shall have no duty to
ascertain or inquire as to the performance or observance of any covenants,
conditions or agreements on the part of any Lessee.

     Section 6.03 Representations or Warranties. The Trustee does not make and
shall not be deemed to have made any representation or warranty as to the
validity, legality or enforceability of this Indenture, the Securities or any
other document or instrument or as to the correctness of any statement contained
in any thereof, except that the Trustee in its individual capacity hereby
represents and warrants (i) that each such specified document to which it is a
party has been or will be duly executed and delivered by one of its officers who

Company Americas in accordance with its terms, subject to the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium or similar law
affecting creditors' rights generally.

     Section 6.04 Reliance; Agents; Advice of Counsel. The Trustee may
conclusively rely upon and shall be fully protected and Incur no liability to
anyone in acting or refraining from acting upon any signature, instrument,
notice, resolution, request, consent, order, certificate, report, opinion, bond
or other document or paper believed by it to be genuine and believed by it to be
signed by the proper party or parties. The Trustee shall have no obligation to
confirm the veracity of the content of any such item provided to it (absent
manifest error). The Trustee may accept a copy of a resolution of, in the case
of the Issuer, the Board and, in the case of any other party to any Related
Document, the governing body of such Person, certified in an accompanying
Officer's Certificate as duly adopted and in full force and effect, as
conclusive evidence that such resolution has been duly adopted and that the same
is in full force and effect. As to any fact or matter the manner of
ascertainment of which is not specifically described herein, the Trustee shall
be entitled to receive and may for all purposes hereof conclusively rely on a
certificate, signed by an officer of any duly authorized Person, as to such fact
or matter, and such certificate shall constitute full protection to the Trustee
for any action taken or omitted to be taken by it in good faith in reliance
thereon. The Trustee shall furnish to the Administrative Agent upon written
request such information and copies of such documents as the Trustee may have
and as are necessary for the Administrative Agent to perform its duties under
Articles II and III hereof. The Trustee shall assume, and shall be fully
protected in assuming, that the Issuer is authorized by its constitutional
documents to enter into this Indenture and to take all action permitted to be
taken by it pursuant to the provisions hereof, and shall not inquire into the
authorization of the Issuer with respect thereto.

          The Trustee shall not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within its rights or
powers or for any action it takes or omits to take in accordance with the
direction of the Controlling Party, in accordance with Section 4.12 hereof
relating to the time, method and place of conducting any proceeding for any
remedy

                                                                             134

Trustee, under this Indenture.

          The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys or a custodian or nominee, and the Trustee shall not be responsible
for any misconduct or negligence on the part of, or for the supervision of, any
such agent, attorney, custodian or nominee appointed with due care by it
hereunder.

          The Trustee may consult with counsel as to any matter relating to this
Indenture and any Opinion of Counsel or any advice of such counsel shall be full
and complete authorization and protection in respect of any action taken or
suffered or omitted by it hereunder in good faith and in accordance with such
advice or Opinion of Counsel.

or powers vested in it by this Indenture, or to institute, conduct or defend any
litigation hereunder or in relation hereto, at the request, order or direction
of any of the Holders, pursuant to the provisions of this Indenture, unless such
Holders shall have offered to the Trustee security or indemnity reasonably
satisfactory to it against the costs, expenses and liabilities which may be
Incurred therein or thereby (the basis of such costs, expenses or liability, if
in respect of any third party liability, shall be supported by an Opinion of
Counsel).

          The Trustee shall not be required to expend or risk its own funds or
otherwise Incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Indenture shall in any event require
the Trustee to perform, or be responsible or liable for the manner of
performance of, any obligations of the Issuer or the Administrative Agent under
this Indenture or any of the Related Documents.

Permitted Account Investments.

          When the Trustee Incurs expenses or renders services in connection
with an Event of Default specified in Section 4.01(e) or 4.01(f) hereof, such
expenses (including the fees and expenses of its counsel) and the compensation
for such services are intended to constitute expenses of administration under
any bankruptcy law or law relating to creditors' rights generally.

          The Trustee shall not be charged with knowledge of an Event of Default
unless a Responsible Officer of the Trustee obtains actual knowledge of such
event, including receiving written notice of such event from the Issuer, the
Administrative Agent, the Policy Provider or any Holder.

Issuer, the Cash Manager or any other party to the Related Documents, nor shall

connection with the malfeasance or nonfeasance by such parties. The Trustee
shall have no liability in connection with the appointment of the Administrative
Agent or compliance by the Issuer, the Administrative Agent, the Cash Manager or
any lessee under a Lease with statutory or regulatory requirements related to
any Aircraft or any Lease. The Trustee shall have no obligation, or liability in
respect thereto, to verify or recalculate any of the determinations made by the
Administrative Agent pursuant to the Related Documents. The Trustee shall not
make or be deemed to have made any representations or warranties with respect to
any Aircraft or any Lease or the validity or sufficiency of any assignment or
other disposition of any Aircraft or any Lease.

     Section 6.05 Not Responsible in Individual Capacity. The Trustee acts
hereunder solely as trustee unless otherwise expressly provided; and all
Persons, other than the Holders to the extent expressly provided in this

contemplated hereby shall look, subject to the lien and priorities of payment as
herein provided, only to the property of the Issuer for payment or satisfaction
thereof.

     Section 6.06 No Compensation from Holders. The Trustee agrees that it shall
have no right against the Holders, the Policy Provider or, except as provided in
Article III hereof, the property of the Issuer, for any fee as compensation for
its services hereunder.

     Section 6.07 Notice of Defaults. As promptly as practicable after, and in
any event within 30 days after, the occurrence of any Default or Event of
Default hereunder, the Trustee shall transmit by mail to the Issuer, the
Guarantor, the Guarantor Trustee, the Controlling Party, the Policy Provider,
the Initial Credit Facility Provider, the Cash Manager, the Rating Agencies and
the Holders holding Securities of the related subclass, notice of such Default
or Event of Default hereunder actually known to a Responsible Officer of the
Trustee, unless such Default shall have been cured or waived.

     Section 6.08 May Hold Securities. The Trustee, any Paying Agent, the
Registrar or any of their Affiliates or any other agent in their respective
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may
otherwise deal with the Issuer with the same rights it would have if it were not
Trustee, Paying Agent, Registrar or such other agent.

     Section 6.09 Corporate Trustee Required; Eligibility. If the Indenture is
qualified under the Trust Indenture Act, there shall at all times be a Trustee
which shall be eligible to act as a trustee under Section 310(a) of the Trust
Indenture Act and shall meet the Eligibility Requirements. If such corporation
publishes reports of conditions at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section 6.09, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

     In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 6.09 to act as Trustee, the Trustee shall
resign immediately as Trustee in the manner and with the effect specified in
Section 7.01 hereof.

                                                                             136

     Section 6.10 Disqualification of Trustee. The Trustee shall be subject to
the provisions of Section 310(b) of the Trust Indenture Act during the period of
time provided for therein. If the Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture.
Nothing herein shall prevent the Trustee from filing with the Commission the
application referred to in the second to last paragraph of Section 310(b) of the
Trust Indenture Act.

     Section 6.11 Preferential Collection of Claims Against Issuer. The Trustee

conditions and covenants under this Indenture (it being understood that for
purposes of this Section 6.12, such compliance shall be determined without
regard to any period of grace or requirement of notice provided under this
Indenture).

          (b) The Issuer shall furnish to the Trustee and the Policy Provider
within 30 days after the end of each calendar quarter a certification as to
compliance with certain of its obligations hereunder and certain other matters
in the form set forth in Exhibit G hereto.

     Section 6.13 Holder Lists. The Issuer will furnish or cause to be furnished
to the Trustee with respect to the Securities of each class:

          (a) semi-annually, not later than 15 days after such semi-annual dates
as may be specified by the Trustee, a list, in such form as the Trustee may
reasonably require, of the names and addresses of the Holders as of such Regular
Record Date or semi-annual date, as the case may be, and

          (b) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Issuer of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished, excluding from any such list names and addresses received by the
Trustee in its capacity as Registrar.

     Section 6.14 Preservation of Information; Communications to Holders. (a)
The Trustee shall preserve, in as current a form as is reasonably practicable,
the names and addresses of Holders contained in the most recent list furnished
to the Trustee as provided in Section 6.13 hereof and the names and addresses of
Holders received by the Trustee in its capacity as Registrar. The Trustee may
destroy any list furnished to it as provided in Section 6.13 hereof upon receipt
of a new list so furnished.

                                                                             137

          (b) If three or more Holders of Securities of any series (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a Security of such
series for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other Holders of Securities of such series or with the Holders
of all Securities with respect to their rights under this Indenture or under
such Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee shall,
within five Business Days after the receipt of such application, at its
election, either

          (i) afford such applicants access to the information preserved at the
time by the Trustee in accordance with Section 6.14(a) hereof, or

          (ii) inform such applicants as to the approximate number of Holders of
Securities of such series or all Securities, as the case may be, whose names and
addresses appear in the information preserved at the time by the Trustee in
accordance with Section 6.14(a) hereof, and as to the approximate cost of
mailing to such Holders the form of proxy or other communication, if any,
specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of a Security of such series or to all Holders,
as the case may be, whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 6.14(a) hereof,
a copy of the form of proxy or other communication which is specified in such
request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses in connection with such mailing.

          (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Issuer and the Trustee that neither the Issuer nor the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders in accordance with Section 6.14(b)
hereof, regardless of the source from which such information was derived, and
that the Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 6.14(b) hereof.

respect to the Subclass

                                                                             138

and such Trustee fails to comply with Section 310 of the TIA after written
request therefor by the Issuer or the Holder of the related subclass who has
been a bona fide Holder for at least six months, (ii) such Trustee fails to
comply with Section 7.02(c) hereof, (iii) such Trustee is adjudged a bankrupt or

subclass; provided that a majority of the Outstanding Principal Balance of such
subclass of the Securities may appoint, within one year after such resignation
or removal, a successor Trustee as to such subclass which may be other than the
successor Trustee appointed by the Issuer, and such successor Trustee appointed
by the Issuer shall be superseded by the successor Trustee so appointed by the
Holders. If a successor Trustee as to any subclass of the Securities shall not
have been appointed and accepted its appointment hereunder within 60 days after
the Trustee gives notice of resignation as to such subclass, the retiring
Trustee, the Issuer, the Administrative Agent, the Cash Manager, the Irish
Remarketing Servicer, the Policy Provider, the Initial Credit Facility Provider
or a majority of the Outstanding Principal Balance of such subclass of the
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee as to such subclass. Any successor Trustee so appointed
by such court shall immediately and without further act be superseded by any
successor Trustee appointed as provided in the first sentence of this paragraph
within one year from the date of the appointment by such court.

          (b) Any successor Trustee as to any subclass of the Securities,
however appointed, shall execute and deliver to the Issuer, the Guarantor, the
Guarantor Trustee, the Administrative Agent, the Cash Manager, the Irish
Remarketing Servicer, the Back-Up Remarketing Servicer, the Policy Provider, the
Initial Credit Facility Provider and the predecessor Trustee as to such subclass
an instrument accepting such appointment, and thereupon such successor Trustee,
without further act, shall become vested with all the estates, properties,
rights, powers, duties and trusts of such predecessor Trustee hereunder in the
trusts hereunder applicable to it with like effect as if originally named the
Trustee as to such subclass herein; provided that, upon the written request of
such successor Trustee, such predecessor Trustee shall, upon payment of all
amounts due and owing to it, execute and deliver an instrument transferring to
such successor Trustee, upon the trusts herein expressed applicable to it, all
the estates, properties, rights, powers and trusts of such predecessor Trustee,
and such predecessor Trustee shall duly assign, transfer, deliver and pay over
to such successor Trustee all

                                                                             139

moneys or other property then held by such predecessor Trustee hereunder solely
for the benefit of such subclass of the Securities.

          (c) If a successor Trustee is appointed with respect to one or more
(but not all) subclasses of the Securities, the Issuer, the predecessor Trustee
and each successor Trustee with respect to each subclass of Securities shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
subclasses of Securities as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the Securities hereunder by more than
one Trustee.

          (d) Each Trustee shall be an Eligible Institution and shall meet the
Eligibility Requirements, if there be such an institution willing, able and
legally qualified to perform the duties of a Trustee hereunder; provided that
the Rating Agencies shall receive notice of any replacement Trustee.

          (e) Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation to which substantially all the business of the Trustee may be
transferred, shall, subject to the terms of paragraph (c) of this Section 7.02,
be the Trustee under this Indenture without further act.

                                  ARTICLE VIII

                                    INDEMNITY

     Section 8.01 Indemnity. The Issuer shall indemnify each of the Trustee and
the Drawing Agent (and its officers, directors, employees and agents) for, and
hold it harmless against, any loss, liability or expense Incurred by it without
negligence or bad faith on its part in connection with the acceptance or
administration of this Indenture and its duties under this Indenture, the
Securities and the other Related Documents, including the costs and expenses of
defending itself against any claim or liability and of complying with any
process served upon it or any of its officers in connection with the exercise or
performance of any of its powers or duties and hold it harmless against, any
loss, liability or reasonable expense Incurred without negligence or bad faith
on its part, arising out of or in connection with actions taken or omitted to be
taken in reliance on any Officer's Certificate furnished hereunder, or the
failure to furnish any such Officers' Certificate required to be furnished
hereunder. Each of the Trustee and the Drawing Agent shall notify the Issuer,
the Guarantor, the Policy Provider and the Initial Credit Facility Provider
promptly of any claim asserted against the Trustee or the Drawing Agent, as
applicable, for which it may seek indemnity; provided, however, that failure to
provide such notice shall not invalidate any right to indemnity hereunder. The
Issuer shall defend the claim and the Trustee or the Drawing Agent, as
applicable, shall cooperate in the defense. The Trustee and the Drawing Agent
may have separate counsel and the Issuer shall pay reasonable fees and expenses
of such counsel. The Issuer need not pay for any settlements made without its
consent; provided that such consent shall not be unreasonably withheld or
delayed. The Issuer need not

                                                                             140

reimburse any expense or indemnity against any loss or liability Incurred by the
Trustee or the Drawing Agent, as applicable, through negligence or bad faith.
The provisions of this Section 8.01 and Section 8.02 hereof shall survive the
termination of this Indenture or the earlier resignation or removal of the
Trustee or the Drawing Agent, as applicable.

     Section 8.02 Holders' Indemnity. Each of the Trustee and the Drawing Agent
shall be entitled to be indemnified (except with respect to losses, damages or
obligations arising from the Trustee's or Drawing Agent's, as applicable,
negligence or bad faith) by the Holders of any subclass of the Securities before
proceeding to exercise any right or power under this Indenture or the Cash
Management Agreement at the request or direction of such Holders (the basis of
any loss, damage or obligation, if in respect of any third party liability,
shall be supported by an Opinion of Counsel).

                                   ARTICLE IX

                                  MODIFICATION

     Section 9.01 Modification with Consent of Holders and the Policy Provider.
With the consent of Holders of a majority of the Outstanding Principal Balance
of the Class A Securities on the date of any vote of such Holders (voting as a
single class), the Policy Provider and the Initial Credit Facility Provider and
upon receipt of a Rating Agency Confirmation, the Issuer, when authorized by one
or more Board Resolutions, may amend or modify this Indenture or the Securities;
provided that (i) without the consent of the Guarantor and the Policy Provider,
no such amendment may modify the provisions of this Indenture to the extent that
such amendment could reasonably be expected to have a material adverse affect on
the Guarantor and (ii) without the consent of the Policy Provider, each provider
of an Eligible Credit Facility, the Guarantor and each Holder of any Securities,
in each instance affected thereby, no such amendment may, except as otherwise
provided in Section 3.11 hereof, modify the provisions of this Indenture or the
Securities setting forth the frequency or the currency of payment of, the
maturity of, or the method of calculation of the amount of, any interest,
principal, Redemption Price or Policy Premium payable in respect of any subclass
of Securities or to the Policy Provider, or reduce the percentage of the
aggregate Outstanding Principal Balance of any subclass of Securities required
to approve any amendment or waiver of this Section 9.01 or, except as otherwise
provided in Section 3.09 hereof, alter the manner or priority of payment of such
subclass of Securities (each, a "Basic Terms Modification").

          It shall not be necessary for the consent of the Holders under this
Section 9.01 to approve the particular form of any proposed amendment or waiver,
but it shall be sufficient if such consent approves the substance thereof;
provided, however, that it shall be necessary for the Policy Provider to approve
the particular form of any proposed amendment or waiver (such approval not to be
unreasonably withheld). Any such modification approved by the required Holders
of any class or subclass of Securities will be binding on the Holders of the
relevant class or subclass of Securities and each party to this Indenture.

          The Issuer shall give the Policy Provider, each provider of an
Eligible Credit Facility and each Rating Agency prior notice of any amendment
under this Section 9.01 and any amendments of the constitutive documents by the
Issuer or any ACS Group Subsidiaries, and,

                                                                             141

after an amendment under this Section 9.01 becomes effective, the Issuer shall
mail to the Holders, the Policy Provider, each provider of an Eligible Credit
Facility and the Rating Agencies a notice briefly describing such amendment. Any
failure of the Issuer to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amendment.

          After an amendment under this Section 9.01 becomes effective, it shall
bind every Holder whether or not notation thereof is made on any Security held
by such Holder.

     Section 9.02 Modification Without Consent of Holders or the Providers of
Eligible Credit Facilities or the Policy Provider. Subject to Section 9.01
hereof, the Trustee may agree with the Issuer, without the consent of any
Holder, the Policy Provider or any provider of an Eligible Credit Facility (but
in the case of clauses (b), (c) and (d) below, with the consent of the Policy
Provider and further, in the case of clause (c) below, with the consent of the
Initial Credit Facility Provider), (a) to any modification (other than a Basic
Terms Modification) of, or the waiver or authorization of any breach or
prospective breach of, any provision of any Related Document or of the relevant
subclass of Securities to correct a manifest error or an error which is of a
formal, minor or technical nature, (b) to modify the provisions of this
Indenture or the Cash Management Agreement relating to the timing of movement of
Rental Payments or other monies received or Expenses Incurred among the Accounts
by the Cash Manager, (c) to add or reflect any Eligible Credit Facility, (d) to
any amendment (other than a Basic Terms Modification) of an immaterial nature
necessary to facilitate the issuance of Refinancing Securities and/or Additional
Securities and related acquisition of Additional Aircraft (all in a manner
consistent with the provisions of this Indenture) or (e) to comply with the
requirements of the Commission in connection with the qualification of this
Indenture under the TIA. Any such modification shall be notified to the Holders
as soon as practicable thereafter and shall be binding on all the Holders.

          Upon any such modification, the Issuer shall deliver to the Holders,
the Trustee, the Policy Provider and the Initial Credit Facility Provider a
certificate of the Issuer certifying that such modification will not adversely
affect the Holders, the Policy Provider or the Initial Credit Facility Provider.

          In addition, the Issuer may, without providing the certificate
mentioned in the preceding paragraph, and without the consent of the Trustee,
any Holder or any provider of an Eligible Facility, the Policy Provider or the
Initial Credit Facility Provider or any other party, list the Securities on the
Alternative Securities Market of the Irish Stock Exchange.

     Section 9.03 Subordination and Priority of Payments. The subordination
provisions contained in Section 3.08, Section 3.09 and Article X hereof may not
be amended or modified without the consent of the Policy Provider (so long as
any subclass of Covered Class A Securities remain outstanding or any Policy
Provider Obligations remain due and owing), each provider of an Eligible Credit
Facility, each Hedge Provider, each Holder of the subclass of Securities
affected thereby and each Holder of any subclass of Securities ranking senior
thereto. In no event shall the provisions set forth in Section 3.08 hereof
relating to the priority of the Expenses, Hedge Payments and payments under all
Eligible Credit Facilities be amended or modified.

                                                                             142

     Section 9.04 Execution of Amendments by Trustee. In executing, or accepting
the additional trusts created by, any amendment or modification to this
Indenture permitted by this Article IX or the modifications thereby of the
trusts created by this Indenture, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officer's Certificate and an
Opinion of Counsel stating that the execution of such amendment is authorized or
permitted by this Indenture. The Trustee may, but shall not be obligated to,
enter into any such amendment which affects the Trustee's own rights, duties,
immunities or indemnities under this Indenture or otherwise.

     Section 9.05 Conformity with Trust Indenture Act. Every indenture
supplemental hereto pursuant to this Article IX shall conform to the
requirements of the Trust Indenture Act as then in effect.

                                    ARTICLE X

                                  SUBORDINATION

     Section 10.01 Subordination of the Securities and Other Subordinated
Obligations. (a) The Issuer, each Holder (by its acceptance of its Security) and
each other Secured Party (by its acceptance of the benefits of the Security
Trust Agreement) agree that (i) the Securities and the other Obligations shall
be subject to the provisions of this Article X and, in the case of the Secured
Obligations, to the provisions of Article VII of the Security Trust Agreement
and (ii) each Subordinated Claimant (and each Subordinated Representative of any
thereof) agree for the benefit of each Senior Claimant (and the Controlling
Party and the Trustee acting therefor) that each Subordinated Claim shall be
subordinated fully in right of payment to each Senior Claim as provided in
Section 3.08 hereof, Section 3.09 hereof (if applicable), this Article X and
Article VII of the Security Trust Agreement.

          (b) For the purposes of this Agreement, no Senior Claims shall be
deemed to have been paid in full until and unless the Senior Claimant (or the
Trustee therefor) of such Senior Claims shall have received payment in full in
cash of such Senior Claims.

          (c) All payments or distributions upon or with respect to any
Obligations that are received by any Subordinated Claimant (or any Subordinated
Representative thereof) contrary to the provisions of this Indenture or in
excess of the amounts to which such Subordinated Claimant is entitled under
Section 3.08 hereof shall be received for the benefit of the Senior Claimant,
shall be segregated from other funds and property held by such Subordinated
Claimant (or any Subordinated Representative therefor) and shall be forthwith
paid over to the Trustee in the same form as so received (with any necessary
endorsement) to be applied (in the case of cash) to or held as collateral (in
the case of non-cash property or securities) for the payment or prepayment of
the Senior Claims in accordance with the terms hereof.

          (d) Notwithstanding anything contained herein to the contrary,
payments (or the proceeds thereof) (i) deposited in any Cash Collateral Account
or drawn under any Eligible Credit Facility, (ii) drawn under the Policy or
(iii) deposited in the Defeasance/Redemption Account (or, in the case of a
Refinancing, the Refinancing Account) in respect of a Redemption under Section
3.10 hereof or in respect of the defeasance of Securities pursuant to Article
XII

                                                                             143

hereof shall not be subordinated to the prior payment of any Senior Claimants in
respect of any Senior Claims or subject to any other restrictions set forth in
this Article X and Article VII of the Security Trust Agreement, and none of the
Holders shall be obligated to pay over any payments from any such property to
the Security Trustee or any other creditor of any of the Grantors (as defined in
the Security Trust Agreement).

          (e) The Senior Representative is hereby authorized to demand specific
performance of the provisions of this Article X at any time when any
Subordinated Claimant (or any Subordinated Representative thereof) shall have
failed to comply with any of such provisions applicable to them. The
Subordinated Claimants (and each Subordinated Representative of any thereof)
hereby irrevocably waive any defense based on the adequacy of a remedy at law
that might be asserted as a bar to such remedy of specific performance.

     Section 10.02 Rights of Subrogation. The Subordinated Claimants (and each
Subordinated Representative of any thereof) agree that no payment or
distribution to any Senior Claimant (or the Trustee therefor) pursuant to the
provisions of this Indenture shall entitle any Subordinated Claimant (or any
Subordinated Representative thereof) to exercise any rights of subrogation in
respect thereof until all Obligations constituting Senior Claims with respect to
such Person shall have been paid in full.

     Section 10.03 Further Assurances of Subordinated Representatives. Each of
the Subordinated Representatives shall, at the expense of the Issuer, at any
time and from time to time promptly execute and deliver all further instruments
and documents, and take all further action, that the Controlling Party (or the
Policy Provider if the Policy Provider is not the Controlling Party; provided
that if the Subordinated Representatives receive conflicting requests, the
request of the Controlling Party shall apply only) may reasonably request, in
order to effectuate the provisions of this Article X.

     Section 10.04 Enforcement. Each Subordinated Claimant (and the Subordinated
Representative therefor) agrees that the provisions of this Article X shall be
enforceable against it under all circumstances, including without limitation in
any proceeding referred to in Sections 4.01(e) and 4.01(f) hereof.

     Section 10.05 Continued Effectiveness. The provisions of this Article X
shall continue to be effective or shall be revived or reinstated, as the case
may be, if at any time any payment of any of the Senior Claims is rescinded or
must otherwise be returned by any Senior Claimant upon the insolvency,
bankruptcy or reorganization of any ACS Ireland Group Member, or otherwise, all
as though such payment had not been made.

     Section 10.06 Senior Claims and Subordinated Claims Unimpaired. Nothing in
this Article X shall impair, as between the Issuer and any Senior Claimant or
any Subordinated Claimant, the obligations of the Issuer to such Person,
including without limitation the Senior Claims and the Subordinated Claims;
provided that it is understood that the enforcement of rights and remedies shall
be subject to the terms of this Indenture and the Security Trust Agreement.

                                                                             144

     Section 10.07 Ranking of the Guarantee. The Guarantor's Guarantee of the
Securities (the "Guarantee") shall rank pari passu with its obligation to make
payments on or otherwise perform in accordance with the terms of the Guarantor
Class A Securities.

                                   ARTICLE XI

                                    GUARANTEE

     Section 11.01 Guarantee. The Guarantor hereby fully and unconditionally
guarantees to each Holder of Securities, the Trustee on behalf of such Holder,
each Service Provider, the Policy Provider, the Initial Credit Facility
Provider, any Hedge Provider and each other Secured Party (each, a "Guaranteed
Party" and, collectively, the "Guaranteed Parties"), in each case, the due and
punctual performance of all obligations of the Issuer to each Guaranteed Party
under the Securities, this Indenture and the Related Documents (the "Guaranteed
Obligations"), all in accordance with this Indenture, the Securities and the
other Related Documents. The liability of the Guarantor under this Guarantee is
limited to the maximum amount that will result in the obligations of the
Guarantor not constituting a fraudulent conveyance or fraudulent transfer under
Applicable Law.

          This Guarantee shall be a Guarantee of payment and performance and not
merely of collection only. The Guarantor hereby agrees that it shall not be
required that any Guaranteed Party assert or enforce any rights against the
Issuer or any other person before or as a condition to the obligation of the
Guarantor subject to this Guarantee.

          The Guarantor hereby waives diligence, presentment, filing of claims
with a court in the event of merger or bankruptcy of the Issuer or any other ACS
Ireland Group Member, any right to require a proceeding first against the Issuer
or any other ACS Ireland Group Member, the benefit of discussion, protest or
notice with respect to any Security or the debt evidenced thereby and all
demands whatsoever (except as specified above), and covenants that this Article
XI shall not be discharged as to any such Security except by payment in full of
the Guaranteed Obligations. The maturity of the Securities and related
obligations guaranteed hereby may be accelerated as provided in Article IV for
the purposes of this Article XI. In the event of any declaration of acceleration
of such obligations as provided in Article IV of this Indenture, such
obligations (whether or not due and payable) shall forthwith become due and
payable by the Guarantor for the purpose of this Article XI. In addition,
without limiting the foregoing provisions, upon the effectiveness of an
acceleration under Article IV of this Indenture, the Trustee shall be entitled
to make a demand for payment on the Securities under the Guarantee provided for
in this Article XI.

          The Guarantor hereby waives any claim or other claim or other rights
which it may now or hereafter acquire against the Issuer or any other ACS
Ireland Group Member that arise from the existence, payment, performance or
enforcement of such Guarantor's obligations under this Indenture, including,
without limitation, any right of subrogation, reimbursement, exoneration,
contribution, indemnification, any right to participate in any claim or remedy
of a Guaranteed Party against the Issuer or any other ACS Ireland Group

                                                                             145

Member, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Issuer or any other ACS Ireland Group Member, directly
or indirectly, in cash or other property or in any other manner, payment or
security on account of such claim or other rights, until all of the Guarantor's
obligations under this Indenture have been satisfied. If any amount shall be
paid to the Guarantor in violation of the preceding sentence and the Guaranteed
Obligations shall not have been paid in full, such amount shall be deemed to
have been paid to the Guarantor for the benefit of, and held in trust for the
benefit of, such Guaranteed Party, and shall forthwith be paid to such
Guaranteed Party. The Guarantor acknowledges that it will receive direct and
indirect benefits from the issuance of the Securities pursuant to this Indenture
and that the waiver set forth in this paragraph is knowingly made in
contemplation of such benefits.

          Any right which at any time the Guarantor has under the existing or
future laws of Ireland and Bermuda to require that recourse be had to the assets
of the Issuer or any other ACS Ireland Group Member before any claim is enforced
against the Guarantor in respect of the obligations hereby assumed by the
Guarantor, is hereby abandoned and waived and the Guarantor undertakes that if
at any time any Guaranteed Party sues the Guarantor in respect of any such
obligations and the Issuer or any other ACS Ireland Group Member is not sued
also, the Guarantor shall not claim that the Issuer or any other ACS Ireland
Group Member be made a party to the proceedings and the Guarantor agrees to be
bound by this guarantee whether or not the Guarantor is made party to legal
proceedings for the recovery of the amount due or owing to such Guaranteed Party
as aforesaid by the Issuer and whether the formalities required by any law of
Ireland whether existing or future in regard to the rights or obligations of
sureties shall or shall not have been observed.

          Any right which the Guarantor may have under the existing or future
laws of Ireland and Bermuda to require that any liability under this Guarantee
be divided or apportioned with any other person or reduced in any manner
whatsoever is hereby abandoned and waived.

          The Guarantee set forth in this Section 11.01 shall not be valid or
become obligatory for any purpose with respect to the Guaranteed Obligations
until the execution of this Indenture or, with respect to a Security, until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee. The Guarantees given by the Guarantor to the Guaranteed
Parties pursuant to this Section 11.01 are, for purposes of this Article XI,
hereinafter referred to as the "Guarantee".

     Section 11.02 Reinstatement. The Guarantor hereby agrees that the guarantee
provided for in Section 11.01 hereof shall continue to be effective or be
reinstated, as the case may be, if at any time, payment, or any part thereof, of
any obligations guaranteed or interest thereon is rescinded or must otherwise be
restored by a Guaranteed Party to the Issuer upon the bankruptcy, reorganization
or insolvency of the Issuer or the Guarantor or otherwise.

     Section 11.03 Unconditional Nature of Guarantee. The Guarantor hereby
agrees that its obligations under the Guarantee shall be irrevocable and
unconditional, irrespective of the validity, regularity or enforceability of the
Securities or this Indenture or any other Related Document against the Issuer or
any other ACS Ireland Group Member, the absence of any action to enforce the
Issuer's or any other ACS Ireland Group Member's obligations under the
Securities, this Indenture or any other Related Document, any waiver or consent
by a Holder with respect to any provisions thereof or any provisions of this
Indenture and the Related

                                                                             146

Documents, any amendment to the terms under which the Securities are issued, any
release of collateral related to the Securities or the Issuer's or any other ACS
Ireland Group Member's obligations under this Indenture or any other Related
Document, the bankruptcy of the Issuer or any other ACS Ireland Group Member or
any circumstance with might otherwise constitute a legal or equitable discharge
or defense of a guarantor; provided, however, that the Guarantor shall be
entitled to exercise any right that the Issuer could have exercised under this
Indenture to cure any default in respect of its obligations under this Indenture
or the Securities, if any, but only to the extent such right, if any, is
provided to the Issuer under this Indenture or the Securities.

          The Guarantor hereby waives each of the following to the fullest
extent of the law: (i) all statutes of limitation as a defense to any action
brought by any party against the Guarantor in connection with this Guarantee,
(ii) any defense based upon (a) the lack of perfection or failure of priority of
any security for the Guaranteed Obligations; (b) any act or omission of any
Guaranteed Party that directly or indirectly results in the discharge or release
of any Issuer or any other Person, or any of the obligations subject to this
Guarantee or any security therefor; or (c) any other defense of the Issuer or
any other Person with respect to the Guaranteed Obligations, whether consensual
or arising by operation of law or any bankruptcy, insolvency or debtor-relief
proceeding, or from any other cause, (iii) any right (whether now or hereafter
existing) to require any Guaranteed Party, as a condition to the enforcement of
this Guarantee, to (a) accelerate the Issuer's obligations, (b) give notice to
the Guarantor of the terms, time and place of any public or private sale of any
security for the Guaranteed Obligations; or (c) exhaust any security for the
Guaranteed Obligations, (iv) any right to presentment, demand, protest and
notice of any kind, including, without limitation, notices of default and
notices of acceptance of this Guarantee, (v) all suretyship defenses and rights
of every nature otherwise available under New York law and the laws of any other
jurisdiction, and (vi) all other rights and defenses, the assertion or exercise
of which would in any way diminish the liability of the Guarantor hereunder.

                                   ARTICLE XII

                       DISCHARGE OF INDENTURE; DEFEASANCE

     Section 12.01 Discharge of Liability on the Securities; Defeasance. (a)
When (i) the Issuer delivers to the Trustee all Outstanding Securities (other
than Securities replaced pursuant to Section 2.08 hereof) for cancellation or
(ii) all Outstanding Securities have become due and payable, whether at maturity
or as a result of the mailing of a notice of redemption pursuant to Section
3.10(c) hereof and the Issuer irrevocably deposits in the Defeasance/Redemption
Account funds sufficient to pay at maturity or upon redemption all Outstanding
Securities, including without limitation interest thereon to maturity or the
Redemption Date (other than Securities replaced pursuant to Section 2.08 hereof
and any Required Expense Amount), and if in either case the Issuer pays all
other sums payable hereunder by the Issuer (including any Hedge Breakage Costs
resulting from the discharge of this Indenture), then this Indenture shall,
subject to Section 12.01(c) hereof, cease to be of further effect. The Trustee
shall acknowledge satisfaction and discharge of this Indenture on demand of the
Issuer accompanied by an Officers'

                                                                             147

Certificate and an Opinion of Counsel, at the cost and expense of the Issuer, to
the effect that any conditions precedent to a discharge of this Indenture have
been met.

          (b) Subject to Sections 12.01(c) and 12.02 hereof, the Issuer at any
time may terminate (i) all its obligations under the Securities and this
Indenture ("Legal Defeasance" option) or (ii) its obligations under Sections
4.01 (other than with respect to a failure to comply with Sections 4.01(a),
4.01(b), 4.01(e) (only with respect to the Issuer) and 4.01(f) (only with
respect to the Issuer)), 5.02 and 5.03 hereof ("Covenant Defeasance" option).
The Issuer may exercise its Legal Defeasance option notwithstanding its prior
exercise of its Covenant Defeasance option.

          If the Issuer exercises its Legal Defeasance option, payment of any
Securities subject to such Legal Defeasance may not be accelerated because of an
Event of Default. If the Issuer exercises its Covenant Defeasance option,
payment of the Securities may not be accelerated because of an Event of Default
(other than with respect to a failure to comply with Sections 4.01(a), 4.01(b),
4.01(e) (other than with respect to the Issuer), 4.01(f) (other than with
respect to the Issuer)) and 5.02(n) hereof.

          Upon satisfaction of the conditions set forth herein and upon request
of the Issuer, the Trustee shall acknowledge in writing the discharge of those
obligations that the Issuer terminates.

          (c) Notwithstanding clauses (a) and (b) above, the Issuer's
obligations in Sections 2.01, 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08 and 2.09,
5.02(n), Article VI, Sections 8.01, 12.04, 12.05 and 12.06 hereof shall survive
until all the Securities have been paid in full. Thereafter, the Issuer's
obligations in Sections 8.01, 12.04 and 12.05 hereof shall survive.

     Section 12.02 Conditions to Defeasance. The Issuer may exercise its Legal
Defeasance option or its Covenant Defeasance option only if:

          (a) the Issuer irrevocably deposits in trust in the
Defeasance/Redemption Account any one or any combination of (i) money, (ii)
obligations of, and supported by the full faith and credit of, the U.S.
Government ("U.S. Government Obligations") or (iii) obligations of corporate
issuers ("Corporate Obligations") (provided that any such Corporate Obligations
are rated AA+ or higher by Standard & Poor's and Aa2 or higher by Moody's at
such time and shall not have a maturity of longer than three years from the date
of defeasance) for the payment of all principal or Redemption Price, and
interest (A) on the Securities or any class or subclass of Securities being
defeased, in the case of Legal Defeasance, or (B) on all of the Securities in
the case of Covenant Defeasance, in either case, to maturity or redemption, as
the case may be;

          (b) the Issuer delivers to the Trustee a certificate from a nationally
recognized firm of independent accountants expressing their opinion that the
payments of principal and interest when due and without reinvestment on the
deposited U.S. Government Obligations or the Corporate Obligations plus any
deposited money without investment will provide cash at such times and in such
amounts as will be sufficient to pay principal and interest when due (i) on each
class or subclass of Securities being defeased, in the case of Legal Defeasance,
or (ii) on all

                                                                             148

of the Securities in the case of Covenant Defeasance, in either case, to
maturity or redemption, as the case may be;

          (c) 91 days pass after the deposit described in clause (a) above is
made and during the 91-day period no Event of Default specified in Section
4.01(e) or (f) hereof with respect to the Issuer occurs which is continuing at
the end of the period;

          (d) the deposit described in clause (a) above does not constitute a
default under any other agreement binding on the Issuer;

          (e) the Issuer delivers to the Trustee an Opinion of Counsel to the
effect that the trust resulting from the deposit described in clause (a) does
not constitute, or is qualified as, a regulated investment company under the
Investment Company Act of 1940, as amended;

          (f) in the case of the Legal Defeasance option, the Issuer shall have
delivered to the Trustee an Opinion of Counsel stating that (i) the Issuer has
received from, or there has been published by, the U.S. Internal Revenue Service
a ruling, or (ii) since the date of this Indenture there has been a change in
the applicable federal income tax law, in either case to the effect that, and
based thereon such opinion of counsel shall confirm that the Holders will not
recognize income, gain or loss for U.S. federal income tax purposes as a result
of such Legal Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred;

          (g) in the case of the Covenant Defeasance option, the Issuer shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders will not recognize income, gain or loss for U.S. federal income tax
purposes as a result of such Covenant Defeasance and will be subject to U.S.
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Covenant Defeasance had not occurred;

          (h) if the related Securities are then listed on any securities
exchange, the Issuer delivers to the Trustee an Opinion of Counsel to the effect
that such deposit, defeasance and discharge will not cause such Securities to be
delisted;

          (i) a Rating Agency Confirmation and the prior written consent of each
of the Policy Provider and the Initial Credit Facility Provider is obtained
relating to the defeasance contemplated by this Section 12.02;

          (j) in the case of a Legal Defeasance only, the Policy shall be
terminated and surrendered to the Policy Provider for cancellation;

          (k) all amounts due and owing to the Policy Provider and the Initial
Credit Facility Provider have been paid (or provided for under Section
12.02(a)); and

          (l) the Issuer delivers to the Trustee an Opinion of Counsel and an
Officer's Certificate that all conditions precedent to such defeasance has been
satisfied.

     Section 12.03 Application of Trust Money. The Trustee shall hold in trust
in the Defeasance/Redemption Account money, U.S. Government Obligations or
Corporate

                                                                             149

Obligations deposited with it pursuant to this Article XII. It shall apply the
deposited money and the money from U.S. Government Obligations or Corporate
Obligations in accordance with this Indenture to the payment of principal,
premium, if any, and interest on the class or subclass of Securities. Money and
securities so held in trust are not subject to Article X hereof or to Article
VII of the Security Trust Agreement.

     Section 12.04 Repayment to Issuer. The Trustee shall promptly turn over to
the Issuer upon written request any excess money or securities held by it at any
time after application of the appropriate defeasance option.

          Subject to any applicable abandoned property law, the Trustee shall
pay to the Issuer upon written request any money held by it for the payment of
principal or interest that remains unclaimed for two years and, thereafter,
Holders entitled to the money must look to the Issuer for payment as general
creditors.

     Section 12.05 Indemnity for Government Obligations and Corporate
Obligations. The Issuer shall pay and shall indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against deposited U.S.
Government Obligations or Corporate Obligations, or the principal and interest
received on such U.S. Government Obligations or Corporate Obligations, which has
been remitted by the Trustee to the U.S. government or any taxing authority.

     Section 12.06 Reinstatement. If the Trustee is unable to apply any money or
U.S. Government Obligations or Corporate Obligations in accordance with this
Article XII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Issuer's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article XII until such time as the Trustee
is permitted to apply all such money, U.S. Government Obligations or Corporate
Obligations in accordance with this Article XII; provided, however, that, if the
Issuer has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Issuer shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money, U.S. Government Obligations or Corporate Obligations held by the Trustee.

                                  ARTICLE XIII

                                  MISCELLANEOUS

     Section 13.01 Right of Trustee to Perform. If the Issuer for any reason
fails to observe or punctually to perform any of its obligations to the Trustee,
whether under this Indenture or any of the other Related Documents or otherwise,
the Trustee shall have power (but shall have no obligation), on behalf of or in
the name of the Issuer or otherwise, to perform such obligations and to take any
steps which the Trustee may, in its absolute discretion, consider appropriate
with a view to remedying, or mitigating the consequences of, such failure by the
Issuer; provided that no exercise or failure to exercise this power by the
Trustee shall in any way prejudice the Trustee's other rights under this
Indenture or any of the other Related Documents.

                                                                             150

     Section 13.02 Waiver. Any waiver by any party of any provision of this
Indenture or any right, remedy or option hereunder shall only prevent and estop
such party from thereafter enforcing such provision, right, remedy or option if
such waiver is given in writing and only as to the specific instance and for the
specific purpose for which such waiver was given. The failure or refusal of any
party hereto to insist in any one or more instances, or in a course of dealing,
upon the strict performance of any of the terms or provisions of this Indenture
by any party hereto or the partial exercise of any right, remedy or option
hereunder shall not be construed as a waiver or relinquishment of any such term
or provision, but the same shall continue in full force and effect. No failure
on the part of the Trustee to exercise, and no delay on its part in exercising,
any right or remedy under this Indenture will operate as a waiver thereof, nor
will any single or partial exercise of any right or remedy preclude any other or
further exercise thereof or the exercise of any other right or remedy. The
rights and remedies provided in this Indenture are cumulative and not exclusive
of any rights or remedies provided by law. The Trustee shall notify the Paying
Agent promptly of any waiver by any party of any provision of this Indenture
pursuant to this Section 13.02.

     Section 13.03 Severability. In the event that any provision of this
Indenture or the application thereof to any party hereto or to any circumstance
or in any jurisdiction governing this Indenture shall, to any extent, be invalid
or unenforceable under any applicable statute, regulation or rule of law, then
such provision shall be deemed inoperative to the extent that it is invalid or
unenforceable and the remainder of this Indenture, and the application of any
such invalid or unenforceable provision to the parties, jurisdictions or
circumstances other than to whom or to which it is held invalid or
unenforceable, shall not be affected thereby nor shall the same affect the
validity or enforceability of this Indenture. The parties hereto further agree
that the holding by any court of competent jurisdiction that any remedy pursued
by the Trustee hereunder is unavailable or unenforceable shall not affect in any
way the ability of the Trustee to pursue any other remedy available to it.

     Section 13.04 Restrictions on Exercise of Certain Rights. (a) The Trustee
and, during the continuance of a payment Default with respect to the Senior
Class, the Senior Trustee, in its capacity as trustee of such class and except
as otherwise provided in Section 4.04 hereof, may sue for recovery or take any
other steps for the purpose of recovering any of the obligations hereunder or
any other debts or liabilities whatsoever owing to it by the Issuer. Each of the
parties hereto and each Holder by virtue of its acceptance of the Securities
(other than the Trustee) hereby agrees that it shall not take any steps for the
purpose of procuring the appointment of an administrative receiver, Irish law
examiner, receiver or similar officer or the making of an administration order
or for instituting any bankruptcy, reorganization, arrangement, insolvency,
winding up, liquidation, composition, Irish law examinership or any like
proceedings under the laws of Ireland.

          (b) If after the occurrence and continuance of an Event of Default,
the obligations of the Issuer in respect of the Securities and any other claims
of any Secured Party will be limited to the net proceeds of the disposal and/or
realization of the Collateral by the Security Trustee pursuant to the provisions
of the Indentures and the Security Trust Agreement, the Secured Parties shall
have no further claim against the Issuer in respect of such unpaid amounts and
will accordingly not have any right hereunder to be able to petition for the
winding up of the Issuer or to take any steps for the purpose of procuring the
appointment of an

                                                                             151

administrative receiver, Irish law examiner, receiver or similar officer or the
making of an administration order or for instituting any bankruptcy,
reorganization, arrangement, insolvency, winding up, liquidation, composition,
Irish law examinership or any like proceedings under the laws of Ireland as a
consequence of such shortfall.

directions, instructions and communications hereunder ("Notices") shall be in

     Section 13.06 Assignments; Third Party Beneficiary. This Indenture shall be
a continuing obligation of the Issuer and shall (i) be binding upon the Issuer
and its successors and assigns and (ii) inure to the benefit of and be
enforceable by the Trustee, and by its successors, transferees and assigns. The
Issuer may not assign any of its obligations under this Indenture, or delegate
any of its duties hereunder. Each Hedge Provider and each provider of an
Eligible Credit Facility shall be a third party beneficiary of this Indenture.

     Section 13.07 Currency Conversion. (a) If any amount is received or
recovered by the Cash Manager or the Trustee in respect of this Indenture or any
part thereof (whether as a result of the enforcement of the security created
under the Security Trust Agreement or pursuant to this Indenture or any judgment
or order of any court or in the liquidation or dissolution of the Issuer or by
way of damages for any breach of any obligation to make any payment under or in
respect of the Issuer's obligations hereunder or any part thereof or otherwise)
in a currency (the "Received Currency") other than the currency in which such
amount was expressed to be payable (the "Agreed Currency"), then the amount in
the Received Currency actually received or recovered by the Trustee or the Cash
Manager shall, to the fullest extent permitted by Applicable Law, only
constitute a discharge to the Issuer to the extent of the amount of the Agreed
Currency which the Cash Manager or the Trustee was or would have been able in
accordance with its normal procedures to purchase on the date of actual receipt
or recovery (or, if that is not practicable, on the next date on which it is so
practicable), and, if the amount of the Agreed Currency which the Cash Manager
or Trustee is or would have been so able to purchase is less than the amount of
the Agreed Currency which was originally payable by the Issuer, the Issuer shall
pay to the Cash Manager such amount as the Cash Manager shall determine to be
necessary to indemnify the Trustee and the Cash Manager against any Loss
sustained by it as a result (including the cost of making any such purchase and
any premiums, commissions or other charges paid or Incurred in connection
therewith) and so that such indemnity, to the fullest extent

                                                                             155

permitted by Applicable Law, (i) shall constitute a separate and independent
obligation of the Issuer distinct from its obligation to discharge the amount
which was originally payable by the Issuer and (ii) shall give rise to a
separate and independent cause of action and apply irrespective of any
indulgence granted by the Cash Manager or the Trustee and continue in full force
and effect notwithstanding any judgment, order, claim or proof for a liquidated
amount in respect of the amount originally payable by the Issuer or any judgment
or order and no proof or evidence of any actual loss shall be required.

          (b) For the purpose of or pending the discharge of any of the moneys
and liabilities hereby secured the Cash Manager may convert any moneys received,
recovered or realized by the Cash Manager under this Indenture (including the
proceeds of any previous conversion under this Section 13.07) from their
existing currency of denomination into the currency of denomination (if
different) of such moneys and liabilities and any conversion from one currency
to another for the purposes of any of the foregoing shall be made at the
Trustee's then prevailing spot selling rate at its office by which such
conversion is made. If not otherwise required to be applied in the Received
Currency, the Cash Manager, acting on behalf of the Security Trustee, shall
promptly convert any moneys in such Received Currency other than U.S. dollars
into U.S. dollars. Each previous reference in this section to a currency extends
to funds of that currency and funds of one currency may be converted into
different funds of the same currency.

     Section 13.08 Application to Court. The Senior Trustee may at any time
after the service of a Default Notice apply to any court of competent
jurisdiction for an order that the terms of this Indenture be carried into
execution under the direction of such court and for the appointment of a
Receiver of the Collateral or any part thereof and for any other order in
relation to the administration of this Indenture as the Senior Trustee shall
deem fit and it may assent to or approve any application to any court of
competent jurisdiction made at the instigation of any of the Holders or the
Policy Provider and shall be indemnified by the Issuer against all costs,
charges and expenses Incurred by it in relation to any such application or
proceedings.

     Section 13.09 Governing Law. THIS INDENTURE SHALL IN ALL RESPECTS BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

     Section 13.10 Jurisdiction. (a) Each of the parties hereto agrees that the

shall have jurisdiction to hear and determine any suit, action or proceeding,
and to settle any disputes, which may arise out of or in connection with this
Indenture and, for such purposes, submits to the jurisdiction of such courts.
Each of the parties hereto waives any objection which it might now or hereafter

            obligations to the Company or any Subsidiary or Affiliate, including
            without limitation repeated refusal to follow the reasonable
            directions of his or her employer, knowing violation of law in the
            course of performance of the duties of Participant's employment with

            (i) the automatic, nondiscretionary grants of Shares shall be made
            to Non-Officer Directors pursuant to and in accordance with the
            terms of Section 11 below and (ii) neither the Board, the Committee
            nor their respective delegates shall have the authority to reprice
            (or cancel and regrant) any Option or, if applicable, other Award at
            a lower exercise, base or purchase price without first obtaining the
            approval of the Company's shareholders.

                        (d)   All decisions made by the Administrator pursuant
            to the provisions of the Plan shall be final, conclusive and binding
            on all persons, including the Company and the Participants. No
            member of the Board or the Committee, nor any officer or employee of
            the Company or any Subsidiary acting on behalf of the Board or the
            Committee, shall be personally liable for any action, omission,
            determination, or interpretation taken or made in good faith with
            respect to the Plan, and all members of the Board or the Committee
            and each and any officer or employee of the Company and of any
            Subsidiary acting on their behalf shall, to the maximum extent
            permitted by law, be fully indemnified and protected by the Company
            in respect of any such action, omission, determination or
            interpretation.

            SECTION 4. SHARES RESERVED FOR ISSUANCE UNDER THE PLAN.

                        (a)   Subject to Section 5 hereof, the total number of
            Shares available for issuance under the Plan shall be equal to
            4,000,000 Shares, as increased by 100,000 Shares on the first day of
            each fiscal year, beginning in 2007 through to and including 2016.
            To the extent it is able, the Company undertakes to make such Shares
            so available for issuance. All such Shares that are available for
            issuance under the Plan shall be available for issuance under
            Incentive Share Options. From and after such time as the Plan is
            subject to Code Section 162(m), the aggregate Awards granted during
            any fiscal year to any single individual who is likely to be a
            "covered employee" as defined

      -10-

            under Code Section 162(m) shall not exceed 2,500,000 Shares.
            Determinations made in respect of the limitation set forth in the
            preceding sentence shall be made in a manner consistent with Section
            162(m) of the Code.

                        (b)   Shares issued or delivered under the Plan may be
            authorized but unissued Shares or Shares acquired on the market or
            otherwise. If any Shares subject to an Award are repurchased or if
            an Award otherwise terminates or expires without an issuance of
            Shares to the Participant, the Shares (or in the event of a
            repurchase of Shares the equivalent number of Shares) with respect
            to such Award shall, to the extent of any such repurchase,
            termination or expiration, again be available for Awards under the
            Plan.

            SECTION 5. EQUITABLE ADJUSTMENTS.

            In the event of any Change in Capitalization, an equitable
substitution or proportionate adjustment shall be made, in each case, in the
manner determined by the Administrator, in (i) the aggregate number of Shares
reserved for issuance under the Plan and the maximum number of Shares that may
be subject to Awards granted to any Participant in any calendar year, (ii) the
kind, number and Exercise Price of Shares subject to outstanding Options and
Share Appreciation Rights granted under the Plan, and (iii) the kind, number and
purchase price of Shares subject to outstanding Awards of Restricted Shares,
Deferred Shares, Performance Shares or Other Share-Based Awards granted under
the Plan, in each case as may be determined by the Administrator, provided,
however, that any fractional shares resulting from the adjustment shall be
eliminated. Such other necessary equitable substitutions or proportionate
adjustments shall be made in the manner determined by the Administrator. Without
limiting the generality of the foregoing, in connection with a Change in
Capitalization, the Administrator may provide for the manner of equitable
substitution to be the cancellation of any outstanding Award granted hereunder
(except fully vested Restricted Shares, fully vested Deferred Shares and fully
vested Performance Shares as to which all restrictions, except any restrictions
described in Section 16(d) hereof, have lapsed) in exchange for payment in cash
or other property of the aggregate Fair Market Value of the Shares covered by
such Award, reduced by the aggregate Exercise Price or purchase price thereof,
if any. Notwithstanding the foregoing, with respect to Incentive Share Options,
any adjustment shall be made in accordance with the provisions of Section 424(h)
of the Code and any regulations or guidance promulgated thereunder, and provided
further that no such adjustment shall cause any Award hereunder which is or
becomes subject to Section 409A of the Code to fail to comply with the
requirements of such Section. The Administrator's determinations pursuant to
this Section 5 shall be final, binding and conclusive.

      -11-

            SECTION 6. ELIGIBILITY.

            Except as set forth in Section 11 below, the Participants under the
Plan shall be selected from time to time by the Administrator, in its sole
discretion, from among Eligible Recipients; provided however that Incentive
Share Options may only be granted to employees of the Company or any Subsidiary.
Notwithstanding the foregoing, Non-Officer Directors shall be eligible for
Awards other than those set forth in Section 11, as determined by the
Administrator from time to time.

            SECTION 7. OPTIONS.

                        (a)   General. Each Participant who is granted an Option
            shall enter into an Award Agreement with the Company, containing
            such terms and conditions as the Administrator shall determine, in
            its discretion, which Award Agreement shall set forth, among other
            things, the Exercise Price of the Option, the term of the Option and
            provisions regarding exercisability of the Option granted
            thereunder. Each Option shall be clearly identified in the
            applicable Award Agreement as either an Incentive Share Option or a
            Nonqualified Share Option. The provisions of each Option need not be
            the same with respect to each Participant. More than one Option may
            be granted to the same Participant and be outstanding concurrently
            hereunder. Options granted under the Plan shall be subject to the
            terms and conditions set forth in this Section 7 and shall contain
            such additional terms and conditions, not inconsistent with the
            terms of the Plan, as the Administrator shall deem desirable that
            are set forth in the applicable Award Agreement.

                        (b)   Exercise Price. The Exercise Price of Shares
            purchasable under an Option shall be determined by the Administrator
            in its sole discretion at the time of grant, provided that the
            Exercise Price of an Incentive Share Option or any Option intended
            to qualify as performance-based compensation under Section 162(m) of
            the Code shall not be less than 100% of the Fair Market Value per
            Share on the date of grant. If a Participant owns or is deemed to
            own (by reason of the attribution rules applicable under Section
            424(d) of the Code) more than 10% of the combined voting power of
            all classes of shares of the Company or of any Subsidiary and an
            Incentive Share Option is granted to such Participant, the Exercise
            Price of such Incentive Share Option (to the extent required at the
            time of grant by the Code) shall be no less than 110% of the Fair
            Market Value per Share on the date such Incentive Share Option is
            granted.

                        (c)   Option Term. The maximum term of each Option shall
            be fixed by the Administrator, but no Option shall be exercisable
            more than ten years after the date such Option is granted.

      -12-

            Each Option's term is subject to earlier expiration pursuant to the
            applicable provisions in the Plan and the Award Agreement.
            Notwithstanding the foregoing, the Administrator shall have the
            authority to accelerate the exercisability of any outstanding Option
            at such time and under such circumstances as it, in it sole
            discretion, deems appropriate.

                        (d)   Exercisability. Each Option shall be exercisable
            at such time or times and subject to such terms and conditions,
            including the attainment of preestablished corporate performance
            goals, as shall be determined by the Administrator in the applicable
            Award Agreement. The Administrator may also provide that any Option
            shall be exercisable only in installments, and the Administrator may
            waive such installment exercise provisions at any time, in whole or
            in part, based on such factors as the Administrator may determine in
            its sole discretion. Notwithstanding anything to the contrary
            contained herein, an Option may not be exercised for a fraction of a
            share.

                        (e)   Method of Exercise. Options may be exercised in
            whole or in part by giving written notice of exercise to the Company
            specifying the number of Shares to be purchased, accompanied by
            payment in full of the aggregate Exercise Price of the Shares so
            purchased in cash or its equivalent, as determined by the
            Administrator. As determined by the Administrator, in its sole
            discretion, with respect to any Option or category of Options,
            payment in whole or in part may also be made (i) in the form of a
            net repurchase of Shares by the Company at Fair Market Value equal
            to the aggregate Exercise Price of such Shares purchased by the
            Participant upon exercise and issued by the Company to the
            Participant, (ii) in the form of repurchase for Fair Market Value of
            unrestricted Shares already owned by the Participant which, (x) in
            the case of unrestricted Shares acquired upon exercise of an Option,
            have been owned by the Participant for more than six months on the
            date of repurchase, and (y) have a Fair Market Value on the date of
            repurchase equal to the aggregate Exercise Price of the Shares as to
            which such Option shall be exercised, (iii) any other form of
            consideration approved by the Administrator and permitted by
            applicable law, (iv) if the Shares are traded on a public exchange,
            through an arrangement with a broker whereby payment of the Exercise
            Price is made with the proceeds of the sale of Shares or (iv) any
            combination of the foregoing.

                        (f)   Limitations on Incentive Share Options. To the
            extent that the aggregate Fair Market Value of the Shares with
            respect to which Incentive Share Options are exercisable for the
            first time by a Participant during any calendar year under the Plan
            and any

      -13-

            other share option plan of the Company shall exceed $100,000, the
            portion of such Incentive Share Options in excess of $100,000 shall
            be treated as Nonqualified Share Options. Such Fair Market Value
            shall be determined as of the date on which each such Incentive
            Share Option is granted. No Incentive Share Option may be granted to
            an individual if, at the time of the proposed grant, such individual
            owns (or is deemed to own under the Code) shares possessing more
            than 10% of the total combined voting power of all classes of shares
            of the Company or of any Subsidiary unless (i) the Exercise Price of
            such Incentive Share Option is at least 110% of the Fair Market
            Value per Share at the time such Incentive Share Option is granted
            and (ii) such Incentive Share Option is not exercisable after the
            expiration of five years from the date such Incentive Share Option
            is granted.

                        (g)   Rights as Shareholder. A Participant shall have no
            rights to dividends or any other rights of a shareholder with
            respect to the Shares subject to an Option until the Participant has
            given written notice of exercise, has paid in full for such Shares,
            has satisfied the requirements of Section 15 hereof and, if
            requested, has given the representation described in paragraph (b)
            of Section 16 hereof, and such Shares have been issued.

                        (h)   Transfers of Options. Except as otherwise
            determined by the Administrator, and in any event in the case of an
            Incentive Share Option, no Option granted under the Plan shall be
            transferable by a Participant otherwise than by will or the laws of
            descent and distribution. Unless otherwise determined by the
            Administrator in accord with the provisions of the immediately
            preceding sentence, an Option may be exercised, during the lifetime
            of the Participant, only by the Participant or, during the period
            the Participant is under a legal disability, by the Participant's
            guardian or legal representative. The Administrator may, in its sole
            discretion, subject to applicable law, permit the gratuitous
            transfer during a Participant's lifetime of a Nonqualified Share
            Option, (i) by gift to a member of the Participant's immediate
            family, (ii) by transfer by instrument to a trust for the benefit of
            such immediate family members, or (iii) to a partnership or limited
            liability company in which such family members are the only partners
            or members; provided, however, that, in addition to such other terms
            and conditions as the Administrator may determine in connection with
            any such transfer, no transferee may further assign, sell,
            hypothecate, charge or otherwise transfer the transferred Option, in
            whole or in part, other than by will or by operation of the laws of
            descent and distribution. Each permitted transferee shall agree to
            be bound by the provisions of this Plan and the applicable Award
            Agreement.

      -14-

                        (i)   Termination of Employment or Service.

                        (1)   Unless the applicable Award Agreement provides
            otherwise, in the event that the employment or service of a
            Participant with the Company or any Subsidiary shall terminate for
            any reason other than Cause, Retirement, Disability, or death, (A)
            Options granted to such Participant, to the extent that they are
            exercisable at the time of such termination, shall remain
            exercisable until the date that is 90 days after such termination,
            on which date they shall expire, and (B) Options granted to such
            Participant, to the extent that they were not exercisable at the
            time of such termination, shall expire at the close of business on
            the date of such termination. The 90-day period described in this
            Section 7(i)(1) shall be extended to one year after the date of such
            termination in the event of the Participant's death during such
            90-day period. Notwithstanding the foregoing, no Option shall be
            exercisable after the expiration of its term.

                        (2)   Unless the applicable Award Agreement provides
            otherwise, in the event that the employment or service of a
            Participant with the Company or any Subsidiary shall terminate on
            account of the Retirement, Disability, or death of the Participant,
            (A) Options granted to such Participant, to the extent that they
            were exercisable at the time of such termination, shall remain
            exercisable until the date that is one year after such termination,
            on which date they shall expire, and (B) Options granted to such
            Participant, to the extent that they were not exercisable at the
            time of such termination, shall expire at the close of business on
            the date of such termination. Notwithstanding the foregoing, no
            Option shall be exercisable after the expiration of its term.

                        (3)   In the event of the termination of a Participant's
            employment or service for Cause, all outstanding Options granted to
            such Participant shall expire at the commencement of business on the
            date of such termination.

                        (j)   Other Change in Employment Status. An Option shall
            be affected, both with regard to vesting schedule and termination,
            by leaves of absence, changes from full-time to part-time
            employment, partial disability or other changes in the employment
            status of an Participant, in the discretion of the Administrator.
            The Administrator shall follow the written policies of the Company
            (if any), including such rules, guidelines and practices as may be
            adopted pursuant to Section 3 hereof, as they may be in effect from
            time to time, with regard to such matters.

      -15-

            SECTION 8. SHARE APPRECIATION RIGHTS.

            (a)   General. Share Appreciation Rights may be granted either
alone ("Free Standing Rights") or in conjunction with all or part of any Share
Option granted under the Plan ("Related Rights"), provided that, in each case,
the Shares underlying the Share Appreciation Rights are traded on an
"established securities market" within the meaning of Section 409A of the Code.
In the case of a Nonqualified Share Option, Related Rights may be granted either
at or after the time of the grant of such Share Option. In the case of an
Incentive Share Option, Related Rights may be granted only at the time of the
grant of the Incentive Share Option. The Administrator shall determine the
Eligible Recipients to whom, and the time or times at which, grants of Share
Appreciation Rights shall be made; the number of Shares to be awarded, the price
per Share, and all other conditions of Share Appreciation Rights.
Notwithstanding the foregoing, no Related Right may be granted for more shares
than are subject to the Share Option to which it relates and any Share
Appreciation Right must be granted with an Exercise Price not less than the Fair
Market Value per Share on the date of grant. The provisions of Share
Appreciation Rights need not be the same with respect to each Participant. Share
Appreciation Rights granted under the Plan shall be subject to the following
terms and conditions set forth in this Section 8 and shall contain such
additional terms and conditions, not inconsistent with the terms of the Plan, as
the Administrator shall deem desirable, as set forth in the applicable Award
Agreement.

            (b)   Awards. The prospective recipient of a Share Appreciation
Right shall not have any rights with respect to such Award, unless and until
such recipient has executed an Award Agreement and delivered a fully executed
copy thereof to the Company, within a period of sixty days (or such other period
as the Administrator may specify) after the award date. Participants who are
granted Share Appreciation Rights shall have no rights as shareholders of the
Company with respect to the grant or exercise of such rights.

            (c)   Exercisability.

                  (1)   Share Appreciation Rights that are Free Standing Rights
("Free Standing Share Appreciation Rights") shall be exercisable at such time or
times and subject to such terms and conditions as shall be determined by the
Administrator at or after grant; provided, however, that no Free Standing Share
Appreciation Right shall be exercisable during the first six months of its term,
except that this additional limitation shall not apply in the event of a
Participant's death or Disability prior to the expiration of such six-month
period.

                  (2)   Share Appreciation Rights that are Related Rights
("Related Share Appreciation Rights") shall be exercisable only at such time or
times and to the extent that the Share Options to which they relate shall be
exercisable in accordance with the provisions of Section 7 above and this
Section 8 of the Plan; provided, however, that a Related Share Appreciation
Right granted in connection with an Incentive Share Option shall be exercisable
only if and when the Fair Market Value per Share of the Shares subject to the
Incentive Share Option exceeds the Exercise Price

      -16-

of such Option; provided, further, that no Related Share Appreciation Right
shall be exercisable during the first six months of its term, except that this
additional limitation shall not apply in the event of a Participant's death or
Disability prior to the expiration of such six-month period.

            (d)   Payment Upon Exercise.

                  (1)   Upon the exercise of a Free Standing Share Appreciation
Right, the Participant shall be entitled to receive up to, but not more than,
that number of Shares equal in value to the excess of the Fair Market Value per
Share as of the date of exercise over the price per Share specified in the Free
Standing Share Appreciation Right (which price shall be no less than 100% of the
Fair Market Value per Share on the date of grant) multiplied by the number of
Shares in respect of which the Free Standing Share Appreciation Right is being
exercised, provided that the Administrator shall have the right to determine the
form of payment in accordance with Section 8(d)(3) hereof.

                  (2)   A Related Right may be exercised by a Participant by
surrendering the applicable portion of the related Option. Upon such exercise
and surrender, the Participant shall be entitled to receive up to, but not more
than, that number of Shares equal in value to the excess of the Fair Market
Value per Share as of the date of exercise over the Exercise Price specified in
the related Option (which price shall be no less than 100% of the Fair Market
Value per Share on the date of grant) multiplied by the number of Shares in
respect of which the Related Share Appreciation Right is being exercised,
provided that the Administrator shall have the right to determine the form of
payment in accordance with Section 8(d)(3) hereof. Options which have been so
surrendered, in whole or in part, shall no longer be exercisable to the extent
the Related Rights have been so exercised.

                  (3)   Notwithstanding the foregoing, the Administrator may
determine to settle the exercise of a Share Appreciation Right in cash (or in
any combination of Shares and cash) to the extent that such settlement does not
result in an excise tax being payable pursuant to Section 409A of the Code.

            (e)   Non-Transferability.

                  (1)   Free Standing Share Appreciation Rights shall be
transferable only when and to the extent that an Option would be transferable
under Section 7 of the Plan.

                  (2)   Related Share Appreciation Rights shall be transferable
only when and to the extent that the underlying Option would be transferable
under Section 7 of the Plan.

            (f)   Termination of Employment or Service.

                  (1)   In the event of the termination of employment or service
with the Company or any Subsidiary of a Participant who has been granted one or
more Free Standing Share Appreciation Rights, such rights shall be exercisable
at such time or

      -17-

times and subject to such terms and conditions as shall be determined by the
Administrator at or after grant.

                  (2)   In the event of the termination of employment or service
with the Company or any Subsidiary of a Participant who has been granted one or
more Related Share Appreciation Rights, such rights shall be exercisable at such
time or times and subject to such terms and conditions as set forth in the
related Share Options.

            (g)   Term.

                  (1)   The term of each Free Standing Share Appreciation Right
shall be fixed by the Administrator, but no Free Standing Share Appreciation
Right shall be exercisable more than ten years after the date such right is
granted.

                  (2)   The term of each Related Share Appreciation Right shall
be the term of the Share Option to which it relates, but no Related Share
Appreciation Right shall be exercisable more than ten years after the date such
right is granted.

            SECTION 9. RESTRICTED SHARES, DEFERRED SHARES AND PERFORMANCE
            SHARES.

            (a)   General. Awards of Restricted Shares, Deferred Shares or
Performance Shares may be issued either alone or in addition to other Awards
granted under the Plan. The Administrator shall determine the Eligible
Recipients to whom, and the time or times at which, Awards of Restricted Shares,
Deferred Shares or Performance Shares shall be made; the number of Shares to be
awarded; the price, if any, to be paid by the Participant for the acquisition of
Restricted Shares, Deferred Shares or Performance Shares; the Restricted Period
(as defined in paragraph (c) of this Section 9), if any, applicable to Awards of
Restricted Shares or Deferred Shares; the performance objectives applicable to
Awards of Restricted Shares, Deferred Shares or Performance Shares; and all
other conditions of the Awards of Restricted Shares, Deferred Shares and
Performance Shares. The Administrator may also condition the grant of the Award
of Restricted Shares, Deferred Shares or Performance Shares upon the exercise of
Options, or upon such other criteria as the Administrator may determine, in its
sole discretion. The provisions of the Awards of Restricted Shares, Deferred
Shares or Performance Shares need not be the same with respect to each
Participant.

            (b)   Awards and Certificates. The prospective recipient of Awards
of Restricted Shares, Deferred Shares or Performance Shares shall not have any
rights with respect to any such Award, unless and until such recipient has
executed an Award Agreement and delivered a fully executed copy thereof to the
Company, within a period of sixty days (or such other period as the
Administrator may specify) after the award date. Except as otherwise provided
below in this Section 9(c), (i) each Participant who is granted an Award of
Restricted Shares or Performance Shares shall, upon the issue of such Shares, be
issued a share certificate in respect of such Restricted Shares or Performance
Shares; and (ii) such certificate shall be registered in the name of the

      -18-

Participant, and shall bear an appropriate legend referring to the terms,
conditions, and restrictions applicable to any such Award.

            The Company may require that the share certificates evidencing
Restricted Shares or Performance Shares granted hereunder be held in the custody
of the Company until the restrictions thereon shall have lapsed, and that, as a
condition of any Award of Restricted Shares or Performance Shares, the
Participant shall have delivered a share transfer form or other document
required by the Administrator relating to the Shares covered by such Award.

            With respect to Awards of Deferred Shares, at the expiration of the
Restricted Period and upon issuance of such Deferred Shares, share certificates
in respect of such Deferred Shares shall be delivered to the Participant, or his
legal representative, in a number equal to the number of Shares covered by the
Deferred Shares Award.

            (c)   Restrictions and Conditions. The Awards of Restricted Shares,
Deferred Shares and Performance Shares granted pursuant to this Section 9 shall
be subject to the following restrictions and conditions and any additional
restrictions or conditions as determined by the Administrator at the time of
grant or thereafter:

                  (1)   Subject to the provisions of the Plan and the Restricted
Shares Award Agreement, Deferred Shares Award Agreement or Performance Shares
Award Agreement, as appropriate, governing any such Award, during such period as
may be set by the Administrator commencing on the date of grant (the "Restricted
Period"), the Participant shall not be permitted to sell, transfer, charge,
pledge or assign Restricted Shares, Deferred Shares or Performance Shares
awarded under the Plan; provided, however, that the Administrator may, in its
sole discretion, provide for the lapse of such restrictions in installments and
may accelerate or waive such restrictions in whole or in part based on such
factors and such circumstances as the Administrator may determine, in its sole
discretion, including, but not limited to, the attainment of certain performance
related goals, the Participant's termination of employment or service as a
director or Consultant to the Company or any Subsidiary, the Participant's death
or Disability. Notwithstanding the foregoing, upon a Change in Control, subject
to applicable law, the provisions of Section 12 shall apply to such outstanding
Awards.

                  (2)   Except as provided in paragraph (c )(l) of this Section
9 or in any relevant Award Agreement, the Participant shall generally have the
rights of a shareholder of the Company with respect to Restricted Shares or
Performance Shares during the Restricted Period. The Participant shall generally
not have the rights of a shareholder with respect to Shares subject to Awards of
Deferred Shares during the Restricted Period; provided, however, that amounts
equal to dividends declared during the Restricted Period with respect to all or
any number of Shares covered by such Award of Deferred Shares may be paid to the
Participant in accordance with a Deferred Shares Award Agreement approved by the
Administrator at the time of the grant of such Award. Certificates for
unrestricted Shares shall be delivered to the Participant promptly after, and
only after, the Restricted Period shall expire without forfeiture (including
repurchase)

      -19-

in respect of such Awards of Restricted Shares, Deferred Shares or Performance
Shares except as the Administrator, in its sole discretion, shall otherwise
determine.

                  (3)   The rights of Participants granted Awards of Restricted
Shares, Deferred Shares or Performance Shares upon termination of employment or
service as a director or Consultant to the Company or to any Subsidiary
terminates for any reason during the Restricted Period shall be set forth in the
Award Agreement.

            SECTION 10. OTHER SHARE-BASED AWARDS.

                              (a)   The Administrator is authorized to grant
            Awards to Participants in the form of Other Share-Based Awards, as
            deemed by the Administrator to be consistent with the purposes of
            the Plan and as evidenced by an Award Agreement. The Administrator
            shall determine the terms and conditions of such Awards, consistent
            with the terms of the Plan, at the date of grant or thereafter,
            including any Performance Goals and performance periods. Shares or
            other securities or property delivered pursuant to an Award in the
            nature of a purchase right granted under this Section 10 shall be
            purchased for such consideration, paid for at such times, by such
            methods, and in such forms, including, without limitation, Shares
            repurchased, other Awards, notes or other property, as the
            Administrator shall determine (provided that the par value of any
            issued Share is paid), subject to any required corporate action.

                              (b)   To the extent that the Plan is subject to
            Section 162(m) of the Code, no payment shall be made to a "covered
            employee" (within the meaning of Section 162(m) of the Code) prior
            to the certification by the Committee that any applicable
            Performance Goals have been attained. The Committee may establish
            other rules applicable to the Other Share-Based Awards, provided,
            however, that in the event that such Other Share-Based Awards are,
            or are likely to be, subject to Section 162(m) of the Code, such
            rules shall be in compliance with Section 162(m) of the Code.

            SECTION 11. NON-OFFICER DIRECTOR GRANTS.

            (a)   Annual Grant. Except as otherwise provided by the
Administrator, on the first business day after the annual general meeting of the
Company in 2007 and each annual general meeting thereafter during the term of
the Plan, each Non-Officer Director shall be granted that number of Shares, the
aggregate Fair Market Value of which shall equal $15,000 on the date of grant
(the "Non-Officer Director Shares"). Any fractional amounts shall be settled in
cash. The Non-Officer Director Shares shall be issued on, and fully vested as
of, the date of grant.

            (b)   Share Availability. In the event that the number of Shares
available for grant under the Plan is not sufficient to accommodate the Awards
of Non-

      -20-

Officer Director Shares, then the remaining Shares available for such automatic
Awards shall be granted to each Non-Officer Director who is to receive such an
Award on a pro-rata basis. No further grants shall be made until such time, if
any, as additional Shares become available for grant under the Plan.

            SECTION 12. ACCELERATED VESTING UPON A CHANGE IN CONTROL.

      Unless otherwise determined by the Administrator and evidenced in an Award
Agreement, in the event of a termination of employment or service by the Company
without Cause within twelve (12) months following a Change of Control, and in
the case of those Participants who are entitled to receive severance under an
employment agreement with the Company upon a termination by the Participant for
good reason (as defined in such employment agreement) upon such a termination
for good reason within twelve (12) months following a Change in Control:

                              (a)   any Award carrying a right to exercise that
            was not previously vested and exercisable shall become fully vested
            and exercisable and shall remain exercisable; and

                              (b)   the restrictions, deferral limitations,
            payment conditions, and forfeiture conditions applicable to any
            other Award granted under the Plan shall immediately lapse and such
            Awards shall be deemed fully vested, and any performance conditions
            imposed with respect to Awards shall be deemed to be fully achieved.

            SECTION 13. AMENDMENT AND TERMINATION.

            The Board may amend, alter or terminate the Plan, but no amendment,
alteration, or termination shall be made that would impair the rights of a
Participant under any Award theretofore granted without such Participant's
consent. Unless the Board determines otherwise, the Board shall obtain approval
of the Company's shareholders for any amendment that would require such approval
in order to satisfy the requirements of Sections 162(m) or 422 of the Code, any
rules of the stock exchange on which the Shares are traded or other applicable
law. The Administrator may amend the terms of any Award theretofore granted,
prospectively or retroactively, but, subject to Section 5 of Plan, no such
amendment shall impair the rights of any Participant without his or her consent.

            SECTION 14. UNFUNDED STATUS OF PLAN.

            The Plan is intended to constitute an "unfunded" plan for incentive
compensation. With respect to any payments not yet made to a Participant by the
Company, nothing contained herein shall give any such Participant any rights
that are greater than those of a general creditor of the Company.

      -21-

            SECTION 15. WITHHOLDING TAXES.

            Whenever cash is to be paid pursuant to an Award granted hereunder,
the Company shall have the right to deduct therefrom an amount sufficient to
satisfy any federal, state and local withholding tax requirements related
thereto. Whenever Shares are to be issued or become vested pursuant to an Award,
the Company shall have the right to require the Participant to remit to the
Company in cash an amount sufficient to satisfy any federal, state and local
withholding tax requirements related thereto. With the approval of the
Administrator, in its sole discretion, the Participant may satisfy the foregoing
requirement by electing to have the Company repurchase unrestricted Shares which
the Participant already owns and in such event the Company shall repurchase such
number of Shares having a value equal to the minimum amount of tax required to
be withheld. Such Shares shall be valued at their Fair Market Value on the date
as of which the amount of tax to be withheld is determined. Any fractional
amounts shall be settled in cash. Such an election may be made with respect to
all or any portion of the Shares to be issued pursuant to an Award.

            SECTION 16. GENERAL PROVISIONS.

                              (a)   Shares shall not be issued or delivered
            pursuant to any Award granted hereunder unless the exercise of such
            Award (if applicable) and/or the issuance and delivery of such
            Shares pursuant thereto shall comply with all relevant provisions of
            law, including, without limitation, Bermuda law, the U.S. Securities
            Act of 1933, as amended, the Exchange Act and the requirements of
            any stock exchange upon which the Shares may then be listed, and
            shall be further subject to the approval of counsel for the Company
            with respect to such compliance.

                              (b)   The Administrator may require each person
            acquiring Shares to represent to and agree with the Company in
            writing that such person is acquiring the Shares without a view to
            distribution thereof. The certificates for such Shares may include
            any legend that the Administrator deems appropriate to reflect any
            restrictions on transfer which the Administrator determines, in its
            sole discretion, arise under applicable securities laws or are
            otherwise applicable.

                              (c)   All Shares issued under the Plan shall be
            subject to such stop-transfer orders and other restrictions as the
            Administrator may deem advisable under the rules, regulations, and
            other requirements of the Securities and Exchange Commission, any
            stock exchange upon which the Shares may then be listed, Bermuda law
            and any applicable federal or state securities law, and the
            Administrator may cause a legend or legends to be placed on any
            certificates representing such Shares to make appropriate reference
            to such restrictions.

      -22-

                              (d)   The Administrator may require a Participant
            receiving Shares pursuant to the Plan, as a condition precedent to
            receipt of such Shares, to enter into a shareholder agreement or
            "lock-up" agreement in such form as the Committee shall determine is
            necessary or desirable to further the Company's interests.

                              (e)   The adoption of the Plan shall not confer
            upon any Eligible Recipient any right to continued employment or
            service with the Company or any Subsidiary, as the case may be, nor
            shall it interfere in any way with the right of the Company or any
            Subsidiary to terminate the employment or service of any of its
            Eligible Recipients at any time.

                              (f)   No Shares shall be issued under the Plan for
            less than par value.

            SECTION 17. EFFECTIVE DATE.

      The Original Plan became effective upon adoption by the Board on January
17, 2006 (the "Effective Date"), subject to requisite approval of shareholders
of the Company and subject to permission being granted by the Bermuda Monetary
Authority pursuant to the Exchange Control Act 1972 (as amended) for the issue
of the Shares pursuant to the Plan.

            SECTION 18. TERM OF PLAN.

            No Award shall be granted pursuant to the Plan on or after the tenth
anniversary of the Effective Date, but Awards theretofore granted may extend
beyond that date.

            SECTION 19. GOVERNING LAW.

            The Plan and all determinations made and actions taken pursuant
hereto shall be governed by the laws of Bermuda.
