                          THE REVOLVING CREDIT FACILITY

          2.1. Revolving Loans.

          (a) Commitment. Subject to the terms and conditions of this Agreement,
     each Lender severally agrees to make Loans to any of the Borrowers under
     the Revolving Credit Facility from time to time from the Closing Date until
     the Revolving Credit Termination Date on a pro rata basis as to the total
     borrowing requested by the applicable Borrower on any day determined by
     such Lender's Applicable Commitment Percentage up to but not exceeding the
     Revolving Credit Commitment of such Lender, provided, however, that (A) the
     proceeds of such Loan shall be used by such Borrower to (i) finance or
     refinance, or reimburse a Borrower for, the Purchase Price of an Eligible
     Aircraft (including additional loans to a Borrower (x) in connection with
     an increase in the Applicable Aircraft Advance Rate as provided in the
     definition thereof or (y) in connection with the acquisition of additional
     Eligible Aircraft, provided that such Aircraft is not subject to a Lease)
     or (ii) reimburse a Borrower for required upfront maintenance, a Qualified
     Conversion and any Approved Improvements, and (B) the amount of such Loan
     (together with any other Loans relating to such Aircraft or additional
     Loans pursuant to clause (A)(y) above) shall not exceed the Applicable
     Aircraft Borrowing Base of such Aircraft; and provided, further, that the
     Lenders will not be required and shall have no obligation to make any such
     Loan (i) so long as a Default or an Event of Default has occurred and is
     continuing or (ii) if the Agent has accelerated the maturity of any of the
     Loans as a result of an Event of Default; and provided, further, that
     immediately after giving effect to each such Loan, the amount of Revolving
     Credit Outstandings shall not exceed the lesser of the Borrowing Base or
     the Total Revolving Credit Commitment. Within such limits, the Borrowers
     may borrow, repay and reborrow under the Revolving Credit Facility on a
     Business Day from the Closing Date until, but (as to borrowings and
     reborrowings) not including, the Revolving Credit Termination Date;
     provided, however, that (1) no Revolving Loan that is a Eurodollar Rate
     Loan shall be made which has an Interest Period that extends beyond the
     first anniversary of the Stated Termination Date and (2) each Revolving
     Loan that is a Eurodollar Rate Loan may, subject to the provisions of
     Section 2.7, be repaid only on the last day of the Interest Period with
     respect thereto unless such payment is accompanied by the additional
     payment, if any, required by Section 4.5. For the avoidance of doubt, if
     the Applicable Aircraft Advance Rate in respect of an Eligible Aircraft
     shall increase after a Loan is made in respect of such Eligible Aircraft,
     then the Applicable Borrower shall be permitted to borrow additional Loans
     in the manner provided above so long as the aggregate Loans in respect of
     such Eligible Aircraft shall not exceed the Applicable Aircraft Borrowing
     Base of such Eligible Aircraft.

          (b) Amounts. Each Revolving Loan hereunder and each Conversion under
     Section 2.8, shall be in an amount of at least $500,000 (other than
     Revolving Loans made


                                       25



     in connection with (i) an increase in the Applicable Aircraft Advance Rate
     as provided in the definition thereof, (ii) an Approved Improvement or
     (iii) a Qualified Conversions).

          (c) Procedures. An Authorized Representative shall give the Agent (i)
     at least three (3) Business Days' irrevocable written notice of an Interest
     Rate Selection Notice with appropriate insertions, effective upon receipt,
     of each Revolving Loan that is to be Converted into a Eurodollar Rate Loan
     prior to 10:30 A.M. and (ii) at least one (1) Business Day's written
     notice, revocable only on or before noon the following Business Day of a
     Borrowing Notice with appropriate insertions, effective upon receipt, of
     each Revolving Loan (which shall be borrowed as a Base Rate Loan) prior to
     10:30 A.M. and (iii) at least one (1) Business Day's irrevocable written
     notice of an Interest Rate Selection Notice with appropriate insertions,
     effective upon receipt, of each Revolving Loan that is to be Converted into
     a Base Rate Loan prior to 10:30 A.M. Each such notice shall (A) specify the
     name of the respective Borrower, the amount of the borrowing, the date of
     borrowing or Conversion (as applicable), type of Revolving Loan (Base Rate
     or Eurodollar Rate), the date of borrowing and, if a Eurodollar Rate Loan,
     the Interest Period to be used in the computation of interest and (B)
     identify the Financed Aircraft the acquisition of which is to be financed
     with the proceeds of the borrowing. Notice of receipt of such Borrowing
     Notice or Interest Rate Selection Notice, as the case may be, together with
     the amount of each Lender's portion of a Loan requested thereunder, shall
     be provided by the Agent to each Lender by facsimile transmission with
     reasonable promptness, but (provided the Agent shall have received such
     notice by 10:30 A.M.) not later than 1:00 P.M. on the same day as the
     Agent's receipt of such notice.

               (i) Promptly (and, to the extent feasible, not later than 2:00
          P.M.) on the date specified for each borrowing under this Section 2.1,
          each Lender shall, pursuant to the terms and subject to the conditions
          of this Agreement, make the amount of the Loan or Loans to be made by
          it on such day available by wire transfer to the Agent in the amount
          of its pro rata share, determined according to such Lender's
          Applicable Commitment Percentage of the Revolving Loan or Revolving
          Loans to be made on such day. Such wire transfer shall be directed to
          the Agent at the Principal Office and shall be in the form of Dollars
          constituting immediately available funds. The amount so received by
          the Agent shall, subject to the terms and conditions of this
          Agreement, be made available to the Applicable Borrower by delivery of
          the proceeds thereof to the Borrowers' Account or otherwise as shall
          be directed in the applicable Borrowing Notice by an Authorized
          Representative and reasonably acceptable to the Agent.

               (ii) Each Loan will be made initially as a Base Rate Loan. The
          Borrowers shall have the option to elect the duration of the initial
          and any subsequent Interest Periods and to Convert the Revolving Loans
          in accordance with Section 2.8. Eurodollar Rate Loans and Base Rate
          Loans may be outstanding at the same time, provided, however, there
          shall not be outstanding at any one time Eurodollar Rate Loans for any
          or any Borrower having more than two (2) different Interest Periods.
          If the Agent does not receive an Interest Rate Selection Notice giving
          notice of election of the duration of an Interest Period by the time
          prescribed by Section 2.8, the applicable Borrower shall be deemed to


                                       26



          have elected for any Eurodollar Loan an Interest Period of the
          duration provided in clause (x) of the definition of Interest Period.

          2.2. Payment of Interest.

          (a) The Borrowers, jointly and severally, shall pay interest to the
     Agent for the account of each Lender on the outstanding and unpaid
     principal amount of each Loan made by such Lender for the period commencing
     on the date of such Loan until such Loan shall be due at the then
     applicable Base Rate for Base Rate Loans or applicable Eurodollar Rate for
     Eurodollar Rate Loans, as designated by the Authorized Representative
     pursuant to Section 2.1; provided, however, that if any Event of Default
     shall occur and be continuing, all amounts outstanding hereunder shall bear
     interest during such period at the Default Rate.

          (b) Interest on each Loan shall be computed on the basis of a year of
     360 days and calculated in each case for the actual number of days elapsed.
     Interest on each Loan shall be paid (x) monthly in arrears on the fifteenth
     (15th) calendar day of each calendar month (or, if such day is not a
     Business Day, on the next succeeding Business Day), (y) upon payment or
     prepayment of the principal amount of any Loan or any portion thereof, on
     the amount so paid or prepaid and (z) at the Revolving Credit Termination
     Date.

          2.3. Payment of Principal.

          (a) Scheduled Repayments; Voluntary Prepayments. The principal amount
     of each Revolving Loan shall be due and payable to the Agent for the
     benefit of each Lender in full on the first anniversary of the Stated
     Termination Date, or earlier as specifically provided herein. The Borrower
     may prepay the outstanding principal amount of any Loan, in whole or in
     part, upon one Business Day's notice to the Lender. All such prepayments
     must be accompanied by accrued interest up to, and including, the date of
     such prepayment and any compensation due under Section 4.5 hereof.

          (b) Mandatory Prepayments.

               (i) Upon the sale of any Aircraft or other asset by any Borrower,
          or upon the refinancing of any Indebtedness of any Borrower arising
          from any Loan hereunder, the Borrowers, jointly and severally, shall
          immediately pay to the Agent an amount equal to the net proceeds of
          such sale or refinancing, which amount shall be applied by the Agent
          to reduce outstanding principal and accrued interest on any Loans made
          to, or for the benefit of, such Borrower. If any net proceeds of such
          sale or refinancing remain after the repayment in full of all
          outstanding principal and accrued interest on such Loans, if no
          Default or Event of Default exists at the time, such excess proceeds
          shall be paid to the Applicable Borrower and may be used by such
          Borrower subject to compliance with the terms of this Agreement and
          the other Loan Documents.

               (ii) The Borrowers, jointly and severally, shall be required to
          prepay the Loans, upon five Business Days' prior notice, in an amount
          equal to any amount by which the aggregate outstanding principal
          amount of the Loans


                                       27



          exceeds the Borrowing Base. Alternatively, a Borrower may pledge
          additional Collateral (valued in a manner reasonably acceptable to the
          Agent) to increase the Borrowing Base and avoid such mandatory
          prepayment.

               (iii) The Borrowers, jointly and severally, shall be required to
          prepay the Loan relating to a Financed Aircraft, upon five Business
          Days' prior notice, in an amount equal to the product of (x) any
          amount by which the estimated out-of-pocket costs incurred by the
          Applicable Borrower in acquiring such Financed Aircraft that were
          included in the Purchase Price exceed the actual amount of such
          expenses and (y) the Applicable Aircraft Advance Rate.

               (iv) The Borrowers, jointly and severally, shall be required to
          prepay the Loans in respect of a Financed Aircraft upon the occurrence
          of an Event of Loss in respect of such Finance Aircraft and on the
          date required by Section 3.8(b) of the Security Agreement. If any net
          proceeds received in respect of such Event of Loss remain after the
          repayment in full of all outstanding principal and accrued interest on
          such Loans, if no Default or Event of Default exists at the time, such
          excess proceeds shall be paid to the Applicable Borrower and may be
          used by such Borrower in its discretion.

               (v) The Borrowers, jointly and severally, shall be required to
          prepay the Loans in the amount distributed for that purpose under
          Section 5.1 of the Lockbox Agreement.

               (vi) Upon any Permanent Capital Markets Financing, the Borrowers,
          jointly and severally, shall be required to prepay the Loans with
          respect to any Aircraft included in such Permanent Capital Markets
          Financing and if such Permanent Capital Markets Financing is competed
          on or after the Stated Termination Date and the net proceeds thereof
          are insufficient to prepay the Loans in full, either (a) the Borrowers
          shall pledge their interest in the trust relating to such Permanent
          Capital Markets Financing or (b) Holding shall continue to pledge its
          right, title and interest in and to the Borrowers, to secure for the
          Loans that thereafter remain outstanding until such Loans shall have
          been paid in full.

          2.4. Manner of Payment. Each payment of principal (including any
prepayment) and payment of interest and fees, and any other amount required to
be paid to the Lenders with respect to the Loans, shall be made to the Agent at
the Principal Office, for the account of each Lender, in Dollars and in
immediately available funds without setoff, deduction or counterclaim before
12:30 P.M. on the date such payment is due.

          (a) The Agent shall deem any payment made by or on behalf of any
     Borrower hereunder that is not made both in Dollars and in immediately
     available funds and prior to 12:30 P.M. to be a non-conforming payment. Any
     such payment shall not be deemed to be received by the Agent until the time
     such funds become available funds. Any non-conforming payment may
     constitute or become a Default or Event of Default. Interest shall continue
     to accrue on any principal as to which a non-conforming payment is made


                                       28



     until the later of (x) the date such funds become available funds or (y)
     the next Business Day at the Default Rate from the date such amount was due
     and payable.

          (b) In the event that any payment hereunder becomes due and payable on
     a day other than a Business Day, then such due date shall be extended to
     the next succeeding Business Day unless provided otherwise under clause
     (ii) of the definition of "Interest Period"; provided that interest shall
     continue to accrue during the period of any such extension and provided,
     further, that in no event shall any such due date be extended beyond the
     Revolving Credit Termination Date.

          (c) Any payment or prepayment of any principal or interest on any Loan
     hereunder shall be accompanied by a certificate signed by an Authorized
     Representative and delivered to the Agent, which certificate shall identify
     such Loan, the amount of principal and interest paid thereon, and the
     Borrower to whom, or for whose benefit, such Loan was originally advanced.

          2.5. Notes. At the request of any Lender, Revolving Loans made by such
Lender shall be evidenced by a Note payable to the order of such Lender in the
respective amount of its Applicable Commitment Percentage of the Revolving
Credit Commitment and shall be duly completed, executed and delivered by the
Borrowers.

          2.6. Pro Rata Payments. Except as otherwise provided herein, (a) each
payment on account of the principal of and interest on the Loans and the fees
described in Section 2.10 shall be made to the Agent for the account of the
Lenders pro rata based on their Applicable Commitment Percentages, (b) all
payments to be made by any Borrower for the account of each of the Lenders on
account of principal, interest and fees, shall be made without diminution,
setoff, recoupment or counterclaim, and (c) the Agent will promptly distribute
to the Lenders in immediately available funds payments received in fully
collected, immediately available funds from any Borrower.

          2.7. Reductions. The Borrowers shall, by notice from an Authorized
Representative, have the right from time to time but not more frequently than
once each calendar month, upon not less than three (3) Business Days' written
notice to the Agent, effective upon receipt, to reduce the Total Revolving
Credit Commitment. The Agent shall give each Lender, within one (1) Business Day
of receipt of such notice, facsimile notice, or telephonic notice (confirmed in
writing), of such reduction. Each such reduction shall be in the aggregate
amount of $5,000,000 or such greater amount which is in an integral multiple of
$1,000,000, or the entire remaining Total Revolving Credit Commitment, and shall
permanently reduce the Total Revolving Credit Commitment. Each reduction of the
Total Revolving Credit Commitment shall be accompanied by payment of the
Revolving Loans to the extent that the principal amount of Revolving Credit
Outstandings exceeds the Total Revolving Credit Commitment after giving effect
to such reduction, together with accrued and unpaid interest on the amounts
prepaid. No such reduction shall result in the payment of any Eurodollar Rate
Loan other than on the last day of the Interest Period of such Eurodollar Rate
Loan unless such prepayment is accompanied by amounts due, if any, under Section
4.5.


                                       29



          2.8. Conversions and Elections of Subsequent Interest Periods. Subject
to the limitations set forth below and in Article IV, the Borrowers may:

          (a) upon delivery, effective upon receipt, of a properly completed
     Interest Rate Selection Notice to the Agent on or before 10:30 A.M. on any
     Business Day, Convert all or a part of Eurodollar Rate Loans to Base Rate
     Loans on the last day of the Interest Period for such Eurodollar Rate
     Loans; and

          (b) provided that no Default or Event of Default shall have occurred
     and be continuing and upon delivery, effective upon receipt, of a properly
     completed Interest Rate Selection Notice to the Agent on or before 10:30
     A.M. three (3) Business Days' prior to the date of such election or
     Conversion:

               (i) elect a subsequent Interest Period for all or a portion of
          Eurodollar Rate Loans to begin on the last day of the then current
          Interest Period for such Eurodollar Rate Loans; and

               (ii) Convert Base Rate Loans to Eurodollar Rate Loans on any
          Business Day.

          Each election and Conversion pursuant to this Section 2.8 shall be
subject to the limitations on Eurodollar Rate Loans set forth in the definition
of "Interest Period" herein and in Sections 2.1, 2.3 and Article IV. The Agent
shall give written notice to each Lender of such notice of election or
Conversion prior to 3:00 P.M. on the day such notice of election or Conversion
is received. All such Continuations or Conversions of Loans shall be effected
pro rata based on the Applicable Commitment Percentages of the Lenders.

          2.9. Increase and Decrease in Amounts. The amount of the Total
Revolving Credit Commitment that shall be available to the Borrowers as Loans
shall be reduced by the aggregate amount of Revolving Credit Outstandings.

          2.10. Fees. Borrower shall pay (i) the fees specified in the Fee
Letter on the dates specified therein and (ii) a commitment fee for the period
from and including the date hereof to the Revolving Credit Termination Date,
computed at a rate of 0.25% per annum on the average daily amount of the
available Revolving Credit Commitment of such Lender during the period for which
payment is made, payable monthly in arrears on each Fee Payment Date, commencing
on the first such date to occur after the date hereof.

          2.11. Deficiency Advances. No Lender shall be responsible for any
default of any other Lender in respect to such other Lender's obligation to make
any Loan hereunder nor shall the Revolving Credit Commitment of any Lender
hereunder be increased as a result of such default of any other Lender. Without
limiting the generality of the foregoing, in the event any Lender shall fail to
advance funds to any Borrower as herein provided, the Agent may in its
discretion and in its capacity as a Lender, but shall not be obligated to,
advance all or any portion of such amount or amounts (each, a "deficiency
advance") and shall thereafter be entitled to payments of principal of and
interest on such deficiency advance in the same manner and at the same interest
rate or rates as if it had originally made such Loan; provided that, (i) such
defaulting Lender shall not be entitled to receive payments of principal,
interest or fees with


                                       30



respect to such deficiency advance until such deficiency advance shall be paid
by such Lender and (ii) upon payment to the Agent from such other Lender of the
entire outstanding amount of each such deficiency advance, together with accrued
and unpaid interest thereon, from the most recent date or dates interest was
paid to the Agent by a Borrower on each Loan comprising the deficiency advance
at the interest rate per annum for overnight borrowing by the Agent from the
Federal Reserve Bank, then such payment shall be to the Agent as a Lender in
full payment of such deficiency advance and such Borrower shall be deemed to
have borrowed the amount of such deficiency advance from such other Lender as of
the most recent date or dates, as the case may be, upon which any payments of
interest were made by such Borrower thereon.

          2.12. Use of Proceeds. The proceeds of each Loan made pursuant to the
Revolving Credit Facility hereunder shall be used by the Applicable Borrower to
finance or refinance, or reimburse a Borrower for the Purchase Price of an
Eligible Aircraft and costs incurred in connection with any Approved
Improvements or any Qualified Conversion.

          2.13. Designation of Borrowing Affiliate; Releases.

          (a) An Authorized Representative may from time to time designate any
     Holdings Subsidiary Trust or Holdings SPC which has not joined in the
     execution of this Agreement as a "Borrowing Affiliate" hereunder by causing
     such Holdings Subsidiary Trust or Holdings SPC to execute and deliver a
     duly completed Assumption Letter (in the form attached hereto as Exhibit Q)
     to the Agent with the written acknowledgment of the Borrowers and the Agent
     at the foot thereof, together with (a) Facility Guaranties executed by each
     Beneficial Owner of any such Holdings Subsidiary Trust, by each Subsidiary
     of any such Beneficial Owner (other than such Holdings Subsidiary Trust),
     by each Subsidiary of such Holdings Subsidiary Trust or of such Holdings
     SPC and by the Applicable Intermediary (if any), (b) Security Agreements
     signed by such Holdings Subsidiary Trust or Holdings SPC, by each
     Beneficial Owner of any such Holdings Subsidiary Trust, by each Subsidiary
     of any such Beneficial Owner, by each Subsidiary of such Holdings
     Subsidiary Trust or Holdings SPC and by the Applicable Intermediary (if
     any), (c) Pledge Agreements signed by the respective Beneficial Owners and
     other owners, granting a security interest in the Pledged Interests in such
     Holdings Subsidiary Trust or Holdings SPC in any Subsidiary thereof, in any
     Beneficial Owner and in any Subsidiary thereof, and in the Applicable
     Intermediary (if any), and (d) all additional documents required under such
     Assumption Letter. Upon such execution, delivery and consent, such Holdings
     Subsidiary Trust or Holdings SPC (as the case may be) shall for all
     purposes be a party hereto as a Borrower as fully as if it had executed and
     delivered this Agreement.

          (b) So long as (w) all Loans made to or on behalf of any Borrower,
     together with all accrued interest on such Loans, have been paid in full,
     (x) all other outstanding Obligations of such Borrower (except Obligations
     to pay principal and interest on Loans other than those Loans described in
     clause (w)) have been paid in full, (y) no Default or Event of Default has
     occurred and will be continuing after giving effect to such termination,
     and (z) any prepayment required under Section 2.3(b) has been made, then
     such Borrower may, by not less than three (3) days prior notice to the
     Agent (which shall promptly notify the Lenders thereof), (i) terminate its
     status as a "Borrowing Affiliate"


                                       31



     and "Borrower" hereunder and under the other Loan Documents, and (ii) (with
     respect to any Beneficial Owner of such Borrower) unless such Person also
     holds a beneficial interest in any other Borrower, terminate the status of
     such Person and any other Subsidiary of such Person as a "Guarantor"
     hereunder and under the other Loan Documents, and (iii) terminate the
     status of the Applicable Intermediary (if any) and any other Subsidiary of
     such Borrower as a "Guarantor" hereunder and under the other Loan
     Documents. Upon such terminations (provided the conditions to such
     terminations are satisfied), the Agent shall take all actions reasonably
     requested by such Borrower (A) to release the Liens of the Agent on all
     Collateral owned by such Borrower and its Subsidiaries (including the
     Applicable Intermediary, if any) and to release such Borrower and such
     Subsidiaries from all of their respective obligations under the Loan
     Documents (including without limitation a written release to such effect),
     (B) unless such Beneficial Owner also holds a beneficial interest in any
     other Borrower, to release the Liens of the Agent on all Collateral owned
     by such Beneficial Owner and its other Subsidiaries and to release such
     Beneficial Owner and such other Subsidiaries from all of their respective
     obligations under the Loan Documents (including without limitation a
     written release to such effect), (C) to release the Lien of the Agent with
     respect to any Pledged Interests in such Borrower, its Subsidiaries and the
     Applicable Intermediary, and (D) (unless such Beneficial Owner also holds a
     beneficial interest in any other Borrower) to release the Lien of the Agent
     with respect to any Pledged Interests in such Beneficial Owner. Any
     provision of this Section 2.13 or any other provision of any Loan Document
     notwithstanding, in no event shall Holdings or Irish Holdings be released
     from its obligations to pay indemnification to, or reimburse any costs or
     expenses of, the Agent or any Lender (including without limitation the
     obligations under Article IV and Sections 4.6, 7.15, 11.5 and 11.9), which
     agreements and obligations shall survive any release or termination of any
     Credit Party (other than Holdings or Irish Holdings) pursuant to this
     Section 2.12.

          (c) So long as (x) all obligations of ABH 12 under the ABH 12-JPM Swap
     Agreement have been paid in full, (y) no Default or Event of Default has
     occurred and will be continuing after giving effect to such termination,
     and (z) any prepayment of interest on the Loans and other Obligations
     required under the ABH 12-JPM Swap Agreement to be made from the proceeds
     of such ABH 12-JPM Swap Agreement has been made, then ABH 12 may, by not
     less than three (3) days prior notice to the Agent (which shall promptly
     notify the Lenders thereof), unless ABH 12 holds a beneficial interest in
     any Borrower, terminate its status as a "Guarantor" hereunder and under the
     other Loan Documents. Upon such termination (provided the conditions to
     such terminations are satisfied), unless ABH 12 becomes a party to this
     Agreement as a "Borrower" or a "Borrowing Affiliate" or holds beneficial
     interest in any Borrower, the Agent shall take all actions reasonably
     requested by ABH 12 to release the Liens of the Agent on all Collateral
     owned by ABH 12 and to release ABH 12 from all of its obligations under the
     Loan Documents (including without limitation a written release to such
     effect).

          2.14. Joint and Several Liability. Each Borrower (including without
limitation each Borrowing Affiliate) agrees and acknowledges that the
Obligations (subject to the proviso in the last sentence in the definition of
"Obligations" as such term is defined in Section 1.1


                                       32



herein) constitute and will constitute joint and several obligations and
liabilities of the Borrowers; provided, however, that anything herein or in any
other Loan Document to the contrary notwithstanding, the maximum liability of
each Borrower with respect to the joint and several liability under this Section
2.14 shall in no event exceed the amount which can be guaranteed by such
Borrower under applicable federal, state and applicable foreign laws relating to
the insolvency of debtors. Each Borrower further agrees and acknowledges that
all actions taken, elections made and notices and certificates furnished or
received by it under or pursuant to the Loan Documents shall constitute the
action, election, notice or certification of all of the Borrowers under the Loan
Documents, and that each Authorized Representative shall have full authority to
act for and on behalf of all of the Borrowers for all purposes of the Loan
Documents. Each Borrower agrees that the joint and several liability of the
Borrowers shall not be impaired or affected by any modification, supplement,
extension or amendment of any contract or agreement to which the parties thereto
may hereafter agree, nor by any modification, release or other alteration of any
of the rights of the Agent or any Lender with respect to the Collateral other
than as provided in Section 2.13(b) hereof, nor by any delay, extension of time,
renewal, compromise or other indulgence granted by the Agent, any Lender or any
other Person with respect to any of the Obligations, nor by any other agreements
or arrangements whatever with any other Borrower or with anyone else, each
Borrower hereby waiving all notice of any such delay, extension, release,
substitution, renewal, compromise or any such delay, extension, release,
substitution, renewal, compromise or other indulgence, and hereby consenting to
be bound thereby as fully and effectually as if it had expressly agreed thereto
in advance. The liability of each Borrower hereunder is direct and unconditional
as to all of the Obligations hereunder, and may be enforced without requiring
the Agent, any Lender or any other Person first to resort to any other right,
remedy or security; no Borrower shall have any right of subrogation,
reimbursement or indemnity whatsoever, nor any right of recourse to security for
indemnity whatsoever, nor any right of recourse to security for any of the
Obligations hereunder, unless and until all of said Obligations have been paid
in full; except as provided in Section 2.13(b) hereof and subject to the proviso
to the first sentence of this Section 2.14, nothing shall discharge or satisfy
the liability of any Borrower hereunder except the full payment and performance
of all of the Obligations; any and all present and future debts and obligations
of each Borrower to the other Borrowers are hereby waived and postponed in favor
of and subordinated to the full payment and performance of all present and
future Obligations of the Borrowers to the Agent, the Lenders and any other
Person.

          2.15. Eligible Lease Involving Eligible Intermediary. In lieu of
leasing a Financed Aircraft directly to an Eligible Carrier, a Borrower may
lease such Financed Aircraft directly to an Eligible Intermediary pursuant to an
Eligible Lease described in clause (X) of the proviso to the definition of
"Eligible Lease"; provided that

          (a) such Eligible Intermediary simultaneously subleases such Aircraft
     to an Eligible Carrier pursuant to an Eligible Lease described in clause
     (Y) of the proviso to the definition of "Eligible Lease" and such sublease
     is pledged as collateral security for the obligations of the Eligible
     Intermediary under the head lease;

          (b) in the case of any Loan with respect to such Aircraft, all Loan
     conditions that pertain to any Eligible Lease or other Lease by a Borrower
     of such Aircraft (including without limitation requirements concerning the
     perfection of Liens on Collateral, and


                                       33



     delivery of copies of the Leases and Lessee Notices) shall be satisfied
     with respect to each such Lease to or by the Applicable Intermediary;

          (c) all provisions of any Loan Document that pertain to any Eligible
     Lease or other Lease by a Borrower of such Aircraft shall apply to each
     such Lease to or by the Applicable Intermediary; and

          (d) the lease/sublease structure shall not result in adverse tax or
     other consequences to the Agent or any Lender which have not been
     indemnified or otherwise addressed to the reasonable satisfaction of the
     Agent.

                                   ARTICLE III

                                    SECURITY

          3.1. Security. As security for the full and timely payment and
performance of all Obligations, the Credit Parties shall on or before the date
of the initial Loan do or cause to be done all things necessary in the
reasonable opinion of the Agent and its counsel to grant to the Agent for the
benefit of the Lenders a duly perfected first priority security interest under
all applicable laws in all Collateral subject to no prior Lien or other
encumbrance (that, in each case, has not previously been satisfied in full) or
restriction on transfer (other than Permitted Liens).

          3.2. Further Assurances. At the request of the Agent, each Borrower
will, or will cause other Credit Parties (as the case may be), to, execute, by
its duly authorized officers, alone or with the Agent, any certificate,
instrument, statement or document, or to procure any such certificate,
instrument, statement or document, or to take such other action (and pay all
connected costs) which the Agent reasonably deems necessary from time to time to
create, continue or preserve the liens and security interests in Collateral (and
the perfection and priority thereof) of the Agent contemplated hereby and by the
other Loan Documents and specifically including all Collateral acquired by any
Borrower or any Guarantor or any other Credit Party after the Closing Date.

          3.3. Information Regarding Collateral. ABH 12 and each Borrower
represents, warrants and covenants that (i) the chief executive office of each
Borrower and each other Person (including ABH 12) providing Collateral pursuant
to a Security Instrument (each, a "Grantor") at the Closing Date is located at
the address or addresses specified on Schedule 3.3, and (ii) Schedule 3.3
contains a true and complete list of (a) the name and address of each Grantor,
(b) each location of the chief executive office and principal place of business
of each Grantor and (c) the country of registration (if applicable) of each
Aircraft. Neither ABH 12, nor any Borrower shall change, or permit any other
Grantor to change, the location of its chief executive office or principal place
of business, or use or permit any other Grantor to use, any additional trade
style, except upon giving not less than thirty (30) days' prior written notice
to the Agent and taking or causing to be taken all such action at the Borrowers'
or such other Grantor's expense as may be reasonably requested by the Agent to
perfect or maintain the perfection of the Lien of the Agent in Collateral.


                                       34



          3.4. Quiet Enjoyment. The Agent and each Lender hereby agree that, so
long as no Lease Event of Default shall have occurred and be continuing under an
Eligible Lease, it will not interfere with the quiet enjoyment of the possession
and use of the Aircraft by the Applicable Carrier during the term of such
Eligible Lease and it will (subject to any requirements or restrictions imposed
by applicable law) dispose of its interest in the Eligible Aircraft leased under
such Eligible Lease expressly subject to such Eligible Lease and on terms such
that the purchaser provides a similar right of quiet enjoyment to such
Applicable Carrier. Upon the request of any Borrower, the Agent (on behalf of
itself and the Lenders) will confirm the immediately preceding sentence in
writing to any Applicable Carrier.

                                   ARTICLE IV

                             CHANGE IN CIRCUMSTANCES

          4.1. Requirements of Law.

          (a) If the adoption of or any change in any Requirement of Law or in
     the interpretation or application thereof or compliance by any Lender with
     any request or directive (whether or not having the force of law) from any
     central bank or other Governmental Authority made subsequent to the date
     hereof:

               (i) shall impose, modify or hold applicable any reserve, special
          deposit, compulsory loan or similar requirement against assets held
          by, deposits or other liabilities in or for the account of, advances,
          loans or other extensions of credit by, or any other acquisition of
          funds by, any office of such Lender that is not otherwise included in
          the determination of the Eurodollar Rate; or

               (ii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost (other than a
Tax) to such Lender, by an amount that such Lender deems to be material, of
making, converting into, continuing or maintaining Eurodollar Rate Loans or to
reduce any amount receivable hereunder in respect thereof (other than by reason
of any Tax), then, in any such case, the Borrowers shall promptly pay such
Lender, upon its demand, any additional amounts necessary to compensate such
Lender for such increased cost or reduced amount receivable. If any Lender
becomes entitled to claim any additional amounts pursuant to this paragraph, it
shall promptly notify the Borrowers (with a copy to the Agent) of the event by
reason of which it has become so entitled.

          (b) If any Lender shall have determined that the adoption of or any
     change in any Requirement of Law regarding capital adequacy or in the
     interpretation or application thereof or compliance by such Lender or any
     corporation controlling such Lender with any request or directive regarding
     capital adequacy (whether or not having the force of law) from any
     Governmental Authority made subsequent to the date hereof shall have the
     effect of reducing the rate of return on such Lender's or such
     corporation's capital as a consequence of its obligations hereunder to a
     level below that which such Lender or such corporation could have achieved
     but for such adoption, change or compliance (taking into consideration such
     Lender's or such corporation's policies with respect to capital


                                       35



     adequacy) by an amount deemed by such Lender to be material, then from time
     to time, after submission by such Lender to the Borrowers (with a copy to
     the Agent) of a written request therefor, the Borrowers shall pay to such
     Lender such additional amount or amounts as will compensate such Lender or
     such corporation for such reduction.

          (c) Each Lender shall promptly notify Holdings, Irish Holdings, the
     Borrowers and the Agent of any event of which it has knowledge occurring
     after the date hereof, which will entitle a Lender to compensation pursuant
     to this Section 4.1, and such Lender shall, upon written request by
     Holdings, Irish Holdings or any Borrower, designate a different Applicable
     Lending Office if such designation will avoid the need for, or reduce the
     amount of, such compensation and will not, in the judgment of such Lender,
     be otherwise disadvantageous to it. A certificate as to any additional
     amounts payable pursuant to this Section submitted by any Lender to the
     Borrowers (with a copy to the Agent) shall be conclusive in the absence of
     manifest error. Notwithstanding anything to the contrary in this Section,
     the Borrowers shall not be required to compensate a Lender pursuant to this
     Section for any amounts incurred more than three months prior to the date
     that such Lender notifies the Borrowers of such Lender's intention to claim
     compensation therefor; provided that, if the circumstances giving rise to
     such claim have a retroactive effect, then such three-month period shall be
     extended to include the period of such retroactive effect. The obligations
     of the Borrowers pursuant to this Section shall survive the termination of
     this Agreement and the payment of the Loans and all other amounts payable
     hereunder.

          4.2. Limitation on Types of Loans. If on or prior to the first day of
any Interest Period for any Eurodollar Rate Loan:

          (a) the Agent determines (which determination shall be conclusive)
     that by reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Eurodollar Rate for such
     Interest Period; or

          (b) the Required Lenders determine (which determination shall be
     conclusive) and notify the Agent that the Eurodollar Rate will not
     adequately and fairly reflect the cost to the Lenders of funding Eurodollar
     Rate Loans for such Interest Period;

then the Agent shall give the Borrowers prompt notice thereof specifying the
relevant Type of Loans and the relevant amounts or periods, and so long as such
condition remains in effect, the Lenders shall be under no obligation to make
additional Loans of such Type, Continue Loans of such Type or to Convert Loans
of any other Type into Loans of such Type, and the Borrowers shall, jointly and
severally, on the last day(s) of the then current Interest Period(s) for the
outstanding Loans of the affected Type, either prepay such Loans or Convert such
Loans into Base Rate Loans in accordance with the terms of this Agreement.

          4.3. Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to make, maintain, or fund Eurodollar Rate Loans
hereunder, then such Lender shall promptly notify the Borrowers thereof and such
Lender's obligation to make or Continue Eurodollar Rate Loans and to Convert
other Types of Loans into Eurodollar Rate Loans shall be suspended until such
time


                                       36



as such Lender may again make, maintain, and fund Eurodollar Rate Loans (in
which case the provisions of Section 4.4 shall be applicable).

          4.4. Treatment of Affected Loans. If the obligation of any Lender to
make a Eurodollar Rate Loan or to Continue, or to Convert Loans of any other
Type into, Loans of a particular Type shall be suspended pursuant to Section 4.1
or 4.3 hereof (Loans of such Type being herein called "Affected Loans" and such
Type being herein called the "Affected Type"), such Lender's Affected Loans
shall be automatically Converted into Base Rate Loans on the last day(s) of the
then current Interest Period(s) for Affected Loans (or, in the case of a
Conversion required by Section 4.3 hereof, on such earlier date as such Lender
may specify to the Borrowers with a copy to the Agent) and, unless and until
such Lender gives notice as provided below that the circumstances specified in
Section 4.1 or 4.3 hereof that gave rise to such Conversion no longer exist:

          (a) to the extent that such Lender's Affected Loans have been so
     Converted, all payments and prepayments of principal that would otherwise
     be applied to such Lender's Affected Loans shall be applied instead to its
     Base Rate Loans; and

          (b) all Loans that would otherwise be made or Continued by such Lender
     as Loans of the Affected Type shall be made or Continued instead as Base
     Rate Loans, and all Loans of such Lender that would otherwise be Converted
     into Loans of the Affected Type shall be Converted instead into (or shall
     remain as) Base Rate Loans.

If such Lender gives notice to the Borrowers (with a copy to the Agent) that the
circumstances specified in Section 4.1 or 4.3 hereof that gave rise to the
Conversion of such Lender's Affected Loans pursuant to this Section 4.4 no
longer exist (which such Lender agrees to do promptly upon such circumstances
ceasing to exist) at a time when Loans of the Affected Type made by other
Lenders are outstanding, such Lender's Base Rate Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Loans of the Affected Type, to the extent necessary so that,
after giving effect thereto, all Loans held by the Lenders holding Loans of the
Affected Type and by such Lender are held pro rata (as to principal amounts,
Types, and Interest Periods) in accordance with their respective Revolving
Credit Commitments.

          4.5. Compensation. Upon the request of any Lender, Holdings, Irish
Holdings and the Borrowers, jointly and severally, shall pay to such Lender such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense incurred by it as a
result of:

          (a) any payment, prepayment, or Conversion of a Eurodollar Rate Loan
     for any reason (including, without limitation, the acceleration of the
     Loans pursuant to Section 9.1) on a date other than the last day of the
     Interest Period for such Loan; or

          (b) any failure by any Borrower for any reason (including, without
     limitation, the failure of any condition precedent specified in Article V
     to be satisfied) to borrow, Convert, Continue, or prepay a Eurodollar Rate
     Loan on the date for such borrowing,


                                       37



     Conversion, Continuation, or prepayment specified in the relevant notice of
     borrowing, prepayment, Continuation, or Conversion under this Agreement.

          4.6. Taxes.

          (a) Any and all payments by any Borrower to or for the account of any
     Lender or the Agent hereunder or under any other Loan Document shall be
     made free and clear of and without deduction or withholding for any and all
     Taxes, and all liabilities with respect thereto, now or hereafter imposed,
     levied, collected, withheld or assessed by any Governmental Authority,
     excluding, in the case of each Lender and the Agent, Taxes imposed on its
     income, receipts, capital, net worth or items of tax preference and
     franchise, doing business and similar Taxes (imposed on it in lieu of net
     income taxes), imposed on such Lender or Agent as a result of a present or
     former connection between the Agent or such Lender and the jurisdiction of
     the Governmental Authority imposing such tax or any political subdivision
     or taxing authority thereof or therein (other than any such connection
     arising solely from the Agent or such Lender having executed, delivered or
     performed its obligations or received a payment under, or enforced, this
     Agreement or any other Loan Document). If any such non-excluded Taxes ("
     Indemnified Taxes") or Other Taxes are required to be withheld after the
     date hereof from or in respect of any sum payable under this Agreement or
     any other Loan Document to any Lender or the Agent, (i) the sum payable
     shall be increased as necessary so that after making all required
     deductions (including deductions applicable to additional sums payable
     under this Section 4.6) such Lender or the Agent receives an amount equal
     to the sum it would have received had no such deductions been made, (ii)
     such Borrower shall make such deductions, (iii) such Borrower shall pay the
     full amount deducted to the relevant taxation authority or other authority
     in accordance with applicable law, and (iv) such Borrower shall furnish to
     the Agent, at its address referred to in Section 11.2, the original or a
     certified copy of a receipt evidencing payment thereof or other evidence of
     payment reasonably acceptable to such Lender or the Agent; provided
     however, that the Borrowers shall not be required to increase such amounts
     payable to any Lender with respect to any Taxes (i) that are attributable
     to such Lender's failure to comply with the requirements of paragraph (d)
     or (e) of this Section or (ii) that are United States withholding taxes
     imposed on amounts payable to such Lender at the time such Lender becomes a
     party to this Agreement, except to the extent that such Lender's assignor
     (if any) was entitled, at the time of assignment, to receive additional
     amounts from the Borrowers with respect to such Taxes pursuant to this
     paragraph.

          (b) In addition, Holdings, Irish Holdings and the Borrowers agree,
     jointly and severally, to pay any and all present or future stamp or
     documentary taxes which arise from the execution or delivery of this
     Agreement or any other Loan Document or the provision of the security
     interest in any Collateral required hereunder (hereinafter referred to as
     "Other Taxes").

          (c) Holdings, Irish Holdings and the Borrowers agree, jointly and
     severally, to indemnify each Lender and the Agent for the full amount of
     Indemnified Taxes and Other Taxes (including, without limitation, any
     Indemnified Taxes or Other Taxes imposed or asserted by any jurisdiction on
     amounts payable under this Section 4.6) paid by such


                                       38



     Lender or the Agent (as the case may be) and any liability (including
     penalties, interest, and expenses) arising therefrom or with respect
     thereto.

          (d) Each Lender, on or prior to the date of its execution and delivery
     of this Agreement in the case of each Lender listed on the signature pages
     hereof and on or prior to the date on which it becomes a Lender in the case
     of each other Lender, and from time to time thereafter if requested in
     writing by any Borrower or the Agent (unless such failure is due to a
     change in treaty, law or regulation occurring subsequent to the date on
     which a form originally was required to be provided), shall provide the
     Borrowers and the Agent with (i) Internal Revenue Service Form W-8BEN,
     W-8ECI or W-8IMY (including all required accompanying information), as
     appropriate, or any successor form prescribed by the Internal Revenue
     Service (including a United States taxpayer identification number),
     certifying that such Lender is entitled to benefits under an income tax
     treaty to which the United States is a party which reduces the rate of
     withholding tax on payments of interest or certifying that the income
     receivable pursuant to this Agreement is effectively connected with the
     conduct of a trade or business in the United States or (ii) Internal
     Revenue Service Form W-9 or any successor form prescribed by the Internal
     Revenue Service. In addition, each Lender and the Agent agrees that it will
     (i) take all actions reasonably requested by Holdings, Irish Holdings or a
     Borrower in writing that are consistent with applicable legal and
     regulatory restrictions to claim any available reductions or exemptions
     from Indemnified Taxes or Other Taxes and (ii) otherwise cooperate with
     Holdings, Irish Holdings and the Borrowers to minimize any amounts payable
     by Holdings, Irish Holdings or the Borrowers under this Section 4.6;
     provided, however, that in each case, any out-of-pocket cost relating to
     such action or cooperation requested by Holdings, Irish Holdings or a
     Borrower shall be borne by Holdings, Irish Holdings or such Borrower and no
     Lender shall be required to take any action that it determines in its sole
     good faith discretion, may be adverse in any non de minimis respect to it
     and not indemnified to its satisfaction.

          (e) A Lender that is entitled to an exemption from or reduction of
     non-U.S. withholding tax under the law of the jurisdiction in which a
     Borrower is located, or any treaty to which such jurisdiction is a party,
     with respect to payments under this Agreement shall deliver to such
     Borrower (with a copy to the Agent), at the time or times prescribed by
     applicable law or reasonably requested by such Borrower, such properly
     completed and executed documentation prescribed by applicable law as will
     permit such payments to be made without withholding or at a reduced rate,
     provided that such Lender is legally entitled to complete, execute and
     deliver such documentation and in such Lender's judgment such completion,
     execution or submission would not materially prejudice the legal position
     of such Lender.

          (f) If Holdings, Irish Holdings or any Borrower is required to pay
     additional amounts to or for the account of any Lender pursuant to this
     Section 4.6, then such Lender will agree to use reasonable efforts to
     change the jurisdiction of its Applicable Lending Office so as to eliminate
     or reduce any such additional payment which may thereafter accrue if such
     change, in the sole judgment of such Lender, is not otherwise
     disadvantageous to such Lender.


                                       39



          (g) Within thirty (30) days after the date of any payment of Taxes,
     Holdings, Irish Holdings or the applicable Borrower shall furnish to the
     Agent the original or a certified copy of a receipt evidencing such payment
     or otherwise evidence of such payment as is reasonably acceptable to the
     Agent.

          (h) If the Agent or any Lender receives a refund of any Taxes or Other
     Taxes as to which it has been indemnified by a Borrower or with respect to
     which a Borrower has paid additional amounts pursuant to this Section 4,6,
     it shall pay over such refund to such Borrower (but only to the extent of
     indemnity payments made, or additional amounts paid, by a Borrower under
     this Section 4.6 with respect to the Taxes or Other Taxes giving rise to
     such refund), net of all out-of-pocket expenses of the Agent or such Lender
     and without interest (other than any interest paid by the relevant
     Governmental Authority with respect to such refund); provided, that the
     Borrower, upon the request of the Agent or such Lender, agrees to repay the
     amount paid over to a Borrower (plus any penalties, interest or other
     charges imposed by the relevant Governmental Authority) to the Agent or
     such Lender in the event the Agent or such Lender is required to repay such
     refund to such Governmental Authority. This paragraph shall not be
     construed to require the Agent or any Lender to make available its tax
     returns (or any other information relating to its taxes which it deems
     confidential) to any Borrower or any other Person.

          (i) Without prejudice to the survival of any other agreement of
     Holdings, Irish Holdings or any Borrower hereunder, the agreements and
     obligations of Holdings, Irish Holdings and each Borrower contained in this
     Section 4.6 shall survive the termination of the Revolving Credit
     Commitments and the payment in full of the Loans.

     any Borrower or such Subsidiary for a period of more than 60 days; or

          (j) if this Agreement or any other Loan Document shall for any reason

     to have a trustee appointed, or a trustee shall be appointed, to administer

     in the termination of such Single Employer Plan for purposes of Title IV of
     ERISA, (iv) any Single Employer Plan shall terminate for purposes of Title
     IV of ERISA, (v) any Borrower or any ERISA Affiliate shall, or in the
     reasonable opinion of the Required Lenders is likely to, incur any
     liability in connection with a withdrawal from, or the Insolvency or
     Reorganization of, a Multemployer Plan or (vi) any other event or condition
     shall occur or exist with respect to a Employee Benefit Plan; and in each
     case in clauses (i) through (vi) above, such event or condition, together
     with all other such events or conditions, if any, could reasonably be
     expected to have a Material Adverse Effect;

then, and in any such event and at any time thereafter, if such Event of Default
or any other Event of Default shall continue to exist and not have been cured or
waived,


                                       65



               (A) either or both of the following actions may be taken: (i) the
          Agent, with the consent of the Required Lenders, may, and at the
          direction of the Required Lenders shall, declare any obligation of the
          Lenders to make further Loans terminated, whereupon the obligation of
          each Lender to make further Loans hereunder shall terminate
          immediately, and (ii) the Agent shall at the direction of the Required
          Lenders, at their option, declare by notice to the Borrowers any or
          all of the Obligations to be immediately due and payable, and the
          same, including all interest accrued thereon and all other obligations
          of any Borrower to the Agent and the Lenders, shall forthwith become
          immediately due and payable without presentment, demand, protest,
          notice or other formality of any kind, all of which are hereby
          expressly waived, anything contained herein or in any instrument
          evidencing the Obligations to the contrary notwithstanding; provided,
          however, that notwithstanding the above, if there shall occur an Event
          of Default under clause (g) or (h) above, then the obligation of the
          Lenders to make Loans hereunder shall automatically terminate and any
          and all of the Obligations shall be immediately due and payable
          without the necessity of any action by the Agent or the Required
          Lenders or notice to the Agent or the Lenders;

               (B) each Borrower shall, upon demand of the Agent or the Required
          Lenders, promptly cause to be performed at Borrowers' expense by
          independent certified public accountants acceptable to the Agent an
          audit of all Financed Aircraft; and

               (C) the Agent and each of the Lenders shall have all of the
          rights and remedies available under the Loan Documents or under any
          applicable law, including without limitation all of the rights and
          remedies of a secured party under any applicable Uniform Commercial
          Code, the FAA Act, the Convention or any other applicable law.

          9.2. Agent to Act. In case any one or more Events of Default shall
occur and not have been waived, the Agent may, and at the direction of the
Required Lenders shall, proceed to protect and enforce their rights or remedies
either by suit in equity or by action at law, or both, whether for the specific
performance of any covenant, agreement or other provision contained herein or in
any other Loan Document, or to enforce the payment of the Obligations or any
other legal or equitable right or remedy.

          9.3. Cumulative Rights. No right or remedy herein conferred upon the
Lenders or the Agent is intended to be exclusive of any other rights or remedies
contained herein or in any other Loan Document, and every such right or remedy
shall be cumulative and shall be in addition to every other such right or remedy
contained herein and therein or now or hereafter existing at law or in equity or
by statute, or otherwise.

          9.4. No Waiver. No course of dealing between any Borrower and any
Lender or the Agent or any failure or delay on the part of any Lender or the
Agent in exercising any rights or remedies under any Loan Document or otherwise
available to it shall operate as a waiver of any rights or remedies and no
single or partial exercise of any rights or remedies shall


                                       66



operate as a waiver or preclude the exercise of any other rights or remedies
hereunder or of the same right or remedy on a future occasion.

          9.5. Allocation of Proceeds. If an Event of Default has occurred and
not been waived, and the maturity of the Loans has been accelerated pursuant to
Article IX hereof, all payments received by the Agent hereunder, in respect of
any principal of or interest on the Obligations or any other amounts payable by
any Borrower hereunder, shall be applied by the Agent in the following order (or
in such manner as the Required Lenders may determine):

          (a) amounts due to the Lenders pursuant to Sections 2.10 and 11.5;

          (b) amounts due to the Agent pursuant to Section 10.8;

          (c) payments of interest on Loans, to be applied for the ratable
     benefit of the Lenders and amounts due to any of the Lenders in respect of
     Obligations consisting of liabilities under the ABH 12-JPM Swap Agreement
     and paid from contributions to ABH 12 pursuant to the Contribution
     Agreement and the Contribution Agreement Guaranty or any Swap Agreement
     with any of the Lenders on a pro rata basis according to the amounts owed;

          (d) payments of principal of Loans, to be applied for the ratable
     benefit of the Lenders;

          (e) amounts due to the Lenders pursuant to Sections 7.15 and 11.9;

          (f) payments of all other amounts due under any of the Loan Documents,
     if any, to be applied for the ratable benefit of the Lenders; and

          (g) any surplus remaining after application as provided for herein, to
     any Borrower or otherwise as may be required by applicable law.

          9.6. Activities of Eligible Carriers. Notwithstanding anything
contained in this Agreement or any other Loan Document, the Credit Parties shall
not be deemed to be in breach of their respective obligations hereunder or
thereunder with respect to the care, maintenance, alteration, possession,
return, replacement, pooling, subleasing, use or operation of any Financed
Aircraft or any part thereof subject to an Eligible Lease by virtue of a default
by the Applicable Carrier under such Eligible Lease so long as each of the
following conditions is satisfied:

          (a) such default by the Applicable Carrier is not within the control
     of any Credit Party;

          (b) the Credit Parties are in compliance with Section 7.19; and

          (c) such default does not relate to any use or location of an Aircraft
     in any jurisdiction that constitutes an Event of Default hereunder, any
     failure to make any payment required by this Agreement or any other Loan
     Document when due hereunder or thereunder, or any failure to maintain any
     insurance required under this Agreement or any


                                       67



     other Loan Document, any failure to maintain perfection of the Agent's Lien
     on any Collateral.

                                   ARTICLE X

                                    THE AGENT

          10.1. Appointment, Powers, and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Agent to act as its agent under this
Agreement and the other Loan Documents, as "Mortgagee" under each Security
Agreement and as "Security Agent" under each Lockbox Agreement (references in
this Article X to the term "Agent" being deemed to include as well such other
capacities), with such powers and discretion as are specifically delegated to
the Agent by the terms of this Agreement and the other Loan Documents, together
with such other powers as are reasonably incidental thereto. The Agent (which
term as used in this sentence and in Section 10.5 and the first sentence of
Section 10.6 hereof shall include its affiliates and its own and its affiliates'
officers, directors, employees, and agents):

          (a) shall not have any duties or responsibilities except those
     expressly set forth in the Loan Documents and shall not be a trustee or
     fiduciary for any Lender;

          (b) shall not be responsible to the Lenders for any recital,
     statement, representation, or warranty (whether written or oral) made in or
     in connection with any Loan Document or any certificate or other document
     referred to or provided for in, or received by any of them under, any Loan
     Document, or for the value, validity, effectiveness, genuineness,
     enforceability, or sufficiency of any Loan Document, or any other document
     referred to or provided for therein or for any failure by any Credit Party
     or any other Person to perform any of its obligations thereunder;

          (c) shall not be responsible for or have any duty to ascertain,
     inquire into, or verify the performance or observance of any covenants or
     agreements by any Credit Party or the satisfaction of any condition or to
     inspect the property (including the books and records) of any Credit Party
     or any of its Subsidiaries or affiliates;

          (d) shall not be required to initiate or conduct any litigation or
     collection proceedings under any Loan Document; and

          (e) shall not be responsible for any action taken or omitted to be
     taken by it under or in connection with any Loan Document, except for its
     own gross negligence or willful misconduct.

The Agent may employ agents and attorneys-in-fact and shall not be responsible
for the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.

          10.2. Reliance by Agent. The Agent shall be entitled to rely upon any
certification, notice, instrument, writing, or other communication (including,
without limitation, any thereof by telephone or facsimile) believed by it to be
genuine and correct and to have been signed, sent or made by or on behalf of the
proper Person or Persons, and upon advice and


                                       68



statements of legal counsel (including counsel for any Credit Party),
independent accountants, and other experts selected by the Agent. The Agent may
deem and treat the payee of any Note as the holder thereof for all purposes
hereof unless and until the Agent receives and accepts an Assignment and
Acceptance executed in accordance with Section 11.1 hereof. As to any matters
not expressly provided for by the Loan Documents, the Agent shall not be
required to exercise any discretion or take any action, but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Required Lenders, and such
instructions shall be binding on all of the Lenders; provided, however, that the
Agent shall not be required to take any action that exposes the Agent to
personal liability or that is contrary to any Loan Document or applicable law or
unless it shall first be indemnified to its satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by reason of
taking any such action.

          10.3. Defaults. The Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default or Event of Default unless the Agent has
received written notice from a Lender or a Borrower specifying such Default or
Event of Default and stating that such notice is a "Notice of Default". In the
event that the Agent receives such a notice of the occurrence of a Default or
Event of Default, the Agent shall give prompt notice thereof to the Lenders. The
Agent shall (subject to Section 10.2 hereof) take such action with respect to
such Default or Event of Default as shall reasonably be directed by the Required
Lenders, provided that, unless and until the Agent shall have received such
directions, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Lenders.

          10.4. Rights as Lender. With respect to its Revolving Credit
Commitment and the Loans made by it, JPMCB (and any successor acting as Agent)
in its capacity as a Lender hereunder shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
acting as the Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Agent in its individual capacity. The
Agent and its affiliates may (without having to account therefor to any Lender)
accept deposits from, lend money to, make investments in, provide services to,
and generally engage in any kind of lending, trust, or other business with any
Credit Party or any of its Subsidiaries or affiliates as if it were not acting
as Agent, and JPMCB (and any successor acting as Agent) and its affiliates may
accept fees and other consideration from any Credit Party or any of its
Subsidiaries or affiliates for services in connection with this Agreement or
otherwise without having to account for the same to the Lenders.

          10.5. Indemnification. The Lenders agree to indemnify the Agent (to
the extent not reimbursed under Section 11.9 hereof, but without limiting the
obligations of any Borrower under such Section) ratably in accordance with their
respective Revolving Credit Commitments, for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses (including reasonable attorneys' fees), or disbursements of any kind
and nature whatsoever that may be imposed on, incurred by or asserted against
the Agent (including by any Lender) in any way relating to or arising out of any
Loan Document or the transactions contemplated thereby or any action taken or
omitted by the Agent under any Loan Document; provided that no Lender shall be
liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Person to be indemnified. Without
limitation of


                                       69



the foregoing, each Lender agrees to reimburse the Agent promptly upon demand
for its ratable share of any costs or expenses payable by any Borrower under
Section 11.5, to the extent that the Agent is not promptly reimbursed for such
costs and expenses by any Borrower. The agreements contained in this Section
10.5 shall survive payment in full of the Loans and all other amounts payable
under this Agreement.

          10.6. Non-Reliance on Agent and Other Lenders. Each Lender agrees that
it has, independently and without reliance on the Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis of the Credit Parties and their Subsidiaries and decision to
enter into this Agreement and that it will, independently and without reliance
upon the Agent or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under the Loan Documents. Except for
notices, reports, and other documents and information expressly required to be
furnished to the Lenders by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition, or business of any
Credit Party or any of its Subsidiaries or affiliates that may come into the
possession of the Agent or any of its affiliates.

          10.7. Resignation of Agent. The Agent may resign at any time by giving
notice thereof to the Lenders and the Borrowers. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Agent, subject (so
long as no Default or Event of Default has occurred and is continuing) to the
written consent of an Authorized Representative, which consent shall not be
unreasonably withheld. If no successor Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty (30)
days after the retiring Agent's giving of notice of resignation, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent which
shall be a commercial bank organized under the laws of the United States of
America having combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor, such successor
shall thereupon succeed to and become vested with all the rights, powers,
discretion, privileges, and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Article
X shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as Agent.

          10.8. Fees. The Borrowers agree, jointly and severally, to pay to the
Agent, for its individual account, an Agent's fee as from time to time agreed to
by any Borrower and the Agent in writing.

                                   ARTICLE XI

                                  MISCELLANEOUS

          11.1. Assignments and Participations. (a) Each Lender may assign to
one or more Eligible Assignees all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Loans, its Note, and its Revolving Credit Commitment); provided, however, that


                                       70



               (i) each such assignment shall be to an Eligible Assignee;

               (ii) except in the case of an assignment to another Lender or an
          assignment of all of a Lender's rights and obligations under this
          Agreement, any such partial assignment shall be in an amount at least
          equal to $5,000,000 or an integral multiple of $1,000,000 in excess
          thereof;

               (iii) each such assignment by a Lender shall be of a constant,
          and not varying, percentage of all of its rights and obligations under
          this Agreement; and

               (iv) the parties to such assignment shall execute and deliver to
          the Agent for its acceptance an Assignment and Acceptance in the form
          of Exhibit B hereto, together with any Note subject to such assignment
          and a processing fee of $3,500 (which amount shall not be payable by
          any Borrower);

               (v) except in the case of an assignment to another Lender, any
          assignment of all or any portion of the Revolving Credit Commitment
          shall require the consent of the Agent and, unless a Default or Event
          of Default has occurred and is continuing, an Authorized
          Representative, such consent in each case not to be unreasonably
          withheld; and

               (vi) neither any Borrower nor Holdings nor Irish Holdings shall
          incur any greater expense or liabilities (including, without
          limitation, indemnities and increased costs) than it would have
          incurred had such assignment not taken place.

Upon execution, delivery, and acceptance of such Assignment and Acceptance, the
assignee thereunder shall be a party hereto and, to the extent of such
assignment, have the obligations, rights, and benefits of a Lender hereunder and
the assigning Lender shall, to the extent of such assignment, relinquish its
rights and be released from its obligations under this Agreement. Upon the
consummation of any assignment pursuant to this Section, the assignor, the Agent
and the Borrowers shall make appropriate arrangements so that, if required, new
Notes are issued to the assignor and the assignee. If the assignee is a Non-U.S.
Lender, it shall deliver to the Borrowers and the Agent certification as to
exemption from deduction or withholding of Taxes in accordance with Section 4.6.

          (b) The Agent shall maintain at its address referred to in Section
     11.2 a copy of each Assignment and Acceptance delivered to and accepted by
     it and a register for the recordation of the names and addresses of the
     Lenders and the Revolving Credit Commitment of, and principal amount of the
     Loans owing to, each Lender from time to time (the "Register"). The entries
     in the Register shall be conclusive and binding for all purposes, absent
     manifest error, and the Borrowers, the Agent and the Lenders may treat each
     Person whose name is recorded in the Register as a Lender hereunder for all
     purposes of this Agreement. The Register shall be available for inspection
     by any Borrower or any Lender at any reasonable time and from time to time
     upon reasonable prior notice.

          (c) Upon its receipt of an Assignment and Acceptance executed by the
     parties thereto, together with any Note subject to such assignment and
     payment of the processing


                                       71



     fee, the Agent shall, if such Assignment and Acceptance has been completed
     and is in substantially the form of Exhibit B hereto, (i) accept such
     Assignment and Acceptance, (ii) record the information contained therein in
     the Register and (iii) give prompt notice thereof to the parties thereto.

          (d) Each Lender may sell participations to one or more Persons in all
     or a portion of its rights, obligations or rights and obligations under
     this Agreement (including all or a portion of its Revolving Credit
     Commitment or its Loans); provided, however, that (i) such Lender s
     obligations under this Agreement shall remain unchanged, (ii) such Lender
     shall remain solely responsible to the other parties hereto for the
     performance of such obligations, (iii) the participant shall be entitled to
     the benefit of the yield protection provisions contained in Article IV and
     the right of set-off contained in Section 11.3, (iv) no Borrower shall have
     any greater obligation to a participant than it would have had to such
     Lender in the absence of the existence of such participant and (v) each
     Borrower shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Agreement,
     and such Lender shall retain the sole right to enforce the obligations of
     any Borrower relating to its Loans and to approve any amendment,
     modification, or waiver of any provision of this Agreement (other than
     amendments, modifications, or waivers decreasing the amount of principal of
     or the rate at which interest or fees are payable on such Loans, extending
     any scheduled principal payment date or date fixed for the payment of
     interest on such Loans, releasing all or substantially all of the
     Collateral (except for a release of Collateral in accordance with Section
     2.13), releasing any Guarantor (except for a release of a Guarantor in
     accordance with Section 2.13), or extending or increasing its Revolving
     Credit Commitment).

          (e) Notwithstanding any other provision set forth in this Agreement,
     any Lender may at any time assign and pledge all or any portion of its
     Loans to any Federal Reserve Bank as collateral security pursuant to
     Regulation A and any Operating Circular issued by such Federal Reserve
     Bank. No such assignment shall release the assigning Lender from its
     obligations hereunder.

          (f) Any Lender may furnish any information concerning any Borrower or
     any of its Subsidiaries in the possession of such Lender from time to time
     to assignees and participants (including prospective assignees and
     participants), subject, however, to the provisions of Section 11.15.

          11.2. Notices. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing (including by

          (d) if to any other Credit Party, at the address set forth on the
     signature page of the Facility Guaranty or Security Instrument executed by
     such Credit Party, as the case may be.

          11.3. Right of Set-off; Adjustments.

          (a) Upon the occurrence and during the continuance of any Event of
     Default, each Lender (and each of its affiliates) is hereby authorized at
     any time and from time to time, to the fullest extent permitted by law, to
     set off and apply any and all deposits (general or special, time or demand,
     provisional or final) at any time held and other indebtedness at any time
     owing by such Lender (or any of its affiliates) to or for the credit or the
     account of any Borrower against any and all of the obligations of any
     Borrower now or hereafter existing under this Agreement and the Note held
     by such Lender, irrespective of whether such Lender shall have made any
     demand under this Agreement or such Note and although such obligations may
     be unmatured. Each Lender agrees promptly to notify the applicable Borrower
     after any such set-off and application made by such Lender; provided,
     however, that the failure to give such notice shall not affect the validity
     of such set-off and application. The rights of each Lender under this
     Section 11.3 are in addition to other rights and remedies (including,
     without limitation, other rights of set-off) that such Lender may have.

          (b) If any Lender (a "benefitted Lender") shall at any time receive
     any payment of all or part of the Loans owing to it, or interest thereon,
     or receive any collateral in respect thereof (whether voluntarily or
     involuntarily, by set-off, or otherwise), in a greater proportion than any
     such payment to or collateral received by any other Lender, if any, in
     respect of such other Lender's Loans owing to it, or interest thereon, such
     benefitted Lender shall purchase for cash from the other Lenders a
     participating interest in such portion of each such other Lender's Loans
     owing to it, or shall provide such other Lenders with the benefits of any
     such collateral, or the proceeds thereof, as shall be necessary to cause
     such benefitted Lender to share the excess payment or benefits of such
     collateral or proceeds ratably with each of the Lenders; provided, however,
     that if all or any portion of such excess payment or benefits is thereafter
     recovered from such benefitted Lender, such purchase shall be rescinded,
     and the purchase price and benefits returned, to the extent of such
     recovery, but without interest. Each Borrower agrees that any Lender so
     purchasing a participation from a Lender pursuant to this Section 11.3 may,
     to the fullest extent permitted by law, exercise all of its rights of
     payment (including the right of set-off) with respect to such participation
     as fully as if such Person were the direct creditor of the Borrowers in the
     amount of such participation.

          11.4. Survival. All covenants, agreements, representations and
warranties made herein shall survive the making by the Lenders of the Loans and
the execution and delivery to the Lenders of this Agreement and any Notes and
shall continue in full force and effect so long as any of Obligations remain
outstanding or any Lender has any Loan hereunder or any Borrower has continuing
obligations hereunder unless otherwise provided herein. Whenever in this
Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and permitted assigns of such party and all
covenants, provisions and agreements


                                       74



by or on behalf of any Borrower which are contained in the Loan Documents shall
inure to the benefit of the successors and permitted assigns of the Lenders or
any of them.

          11.5. Expenses. Holdings, Irish Holdings and each Borrower agree,
jointly and severally, to pay on demand (subject, in the case of preparation,
execution, delivery and administration costs, to the Fee Letter), all reasonable
costs and expenses of the Agent in connection with the preparation, execution,
delivery, administration, modification, and amendment of this Agreement, the
other Loan Documents, subject to any cap that may have otherwise been agreed,
and the other documents to be delivered hereunder, including, without
limitation, the reasonable fees and expenses of counsel for the Agent (excluding
the cost of internal counsel) with respect thereto and with respect to advising
the Agent as to its rights and responsibilities under the Loan Documents.
Holdings, Irish Holdings and each Borrower further agree, jointly and severally,
to pay on demand all costs and expenses of the Agent and the Lenders, if any
(including, without limitation, reasonable external attorneys' fees and
expenses), in connection with the enforcement (whether through negotiations,
legal proceedings, or otherwise) of the Loan Documents and the other documents
to be delivered hereunder.

          11.6. Amendments and Waivers. Any provision of this Agreement or any
other Loan Document may be amended or waived if, but only if, such amendment or
waiver is in writing and is signed by the Borrowers and each Lender (and, if
Article X or the rights or duties of the Agent are affected thereby, by the
Agent);

          No notice to or demand on any Borrower in any case shall entitle such
Borrower or any other Borrower to any other or further notice or demand in
similar or other circumstances, except as otherwise expressly provided herein.
No delay or omission on any Lender's or the Agent's part in exercising any
right, remedy or option shall operate as a waiver of such or any other right,
remedy or option or of any Default or Event of Default.

          11.7. Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed an
original, and it shall not be necessary in making proof of this Agreement to
produce or account for more than one such fully-executed counterpart.

          11.8. Return of Funds. If after receipt of any payment of all or any
part of the Obligations, any Lender is for any reason compelled to surrender
such payment to any Person because such payment is determined to be void or
voidable as a preference, impermissible setoff, a diversion of trust funds or
for any other reason, this Agreement shall continue in full force and each
Borrower, jointly and severally, shall be liable to, and shall indemnify and
hold the Agent or such Lender harmless for, the amount of such payment
surrendered until the Agent or such Lender shall have been finally and
irrevocably paid in full. The provisions of the foregoing sentence shall be and
remain effective notwithstanding any contrary action which may have been taken
by the Agent or the Lenders in reliance upon such payment, and any such contrary
action so taken shall be without prejudice to the Agent or the Lenders' rights
under this Agreement and shall be deemed to have been conditioned upon such
payment having become final and irrevocable.


                                       75



          11.9. Indemnification; Limitation of Liability.

          (a) Holdings, Irish Holdings and each Borrower, jointly and severally,
     agree to indemnify and hold harmless the Agent (which term for purposes of
     this Section 11.9 includes the "Mortgagee" under each Security Agreement
     and the "Security Agent" under each Lockbox Agreement) and each Lender and
     each of their affiliates and their respective officers, directors,
     employees, agents, and advisors (each, an "Indemnified Party") from and
     against any and all claims, damages, losses, liabilities, costs, and
     expenses (including, without limitation, reasonable external attorneys'
     fees, but excluding principal and accrued interest on any Loan) that may be
     incurred by or asserted or awarded against any Indemnified Party, in each
     case arising out of or in connection with or by reason of (including,
     without limitation, in connection with any investigation, litigation, or
     proceeding or preparation of defense in connection therewith) the Loan
     Documents, any of the transactions contemplated herein, any Aircraft or
     other Collateral, any possession, performance, transportation, management,
     sale, ownership, registration, mortgage, charging, control, maintenance,
     service, repair, design, testing, defect, overhaul, purchase, bearing, use
     or operation of any Aircraft or other Collateral, or the actual or proposed
     use of the proceeds of the Loans, except to the extent such claim, damage,
     loss, liability, cost, or expense is found in a final, non-appealable
     judgment by a court of competent jurisdiction to have resulted from such
     Indemnified Party's gross negligence or willful misconduct. In the case of
     an investigation, litigation or other proceeding to which the indemnity in
     this Section 11.9 applies, such indemnity shall be effective whether or not
     such investigation, litigation or proceeding is brought by Holdings, Irish
     Holdings, any Borrower, its directors, shareholders or creditors or an
     Indemnified Party or any other Person or any Indemnified Party is otherwise
     a party thereto and whether or not the transactions contemplated hereby are
     consummated. Holdings, Irish Holdings and each Borrower agree that no
     Indemnified Party shall have any liability (whether direct or indirect, in
     contract or tort or otherwise) to it, any of its Subsidiaries, any
     Guarantor or any security holders or creditors thereof arising out of,
     related to or in connection with the transactions contemplated in any Loan
     Document, except to the extent that such liability directly results from
     such Indemnified Party's gross negligence or willful misconduct. Holding,
     Irish Holdings and each Borrower agree not to assert any claim against the
     Agent, any Lender, any of their affiliates, or any of their respective
     directors, officers, employees, attorneys, agents, and advisers, on any
     theory of liability, for special, indirect, consequential, or punitive
     damages arising out of or otherwise relating to the Loan Documents, any of
     the transactions contemplated herein or the actual or proposed use of the
     proceeds of the Loans.

          (b) Without prejudice to the survival of any other agreement of
     Holdings, Irish Holdings or any Borrower hereunder, the agreements and
     obligations of Holdings, Irish Holdings and each Borrower contained in this
     Section 11.9 shall survive the payment in full of the Loans and all other
     amounts payable under this Agreement.

          (c) Except as expressly provided herein, each Lender, each Borrower
     and the Agent agree that this Agreement and each other Loan Document
     entered into by a Holdings Subsidiary Trust is executed by a Qualified
     Trustee, not individually but solely as Trustee under a Trust Agreement in
     the exercise of the power and authority conferred


                                       76



     and vested in it as such Trustee, that each and all of the representations,
     undertakings and agreements by a Qualified Trustee, or for the purpose or
     with the intention of binding a Qualified Trustee, are made and intended
     for the purpose of binding only the Trust Estates (and, to the extent any
     Lender, Borrower or Agent has an interest therein, any liability insurance
     proceeds), and that in no case whatsoever shall any Qualified Trustee be
     personally liable for any loss in respect of such representations,
     undertakings and agreements, that nothing herein contained shall be
     construed as creating any liability on any Qualified Trustee individually
     or personally, to perform any covenant, either express or implied, herein,
     all such liability, if any, being expressly waived by each Lender, each
     Borrower and the Agent and by each and every Person now or hereafter
     claiming by, through or under such Persons except with respect to the gross
     negligence or willful misconduct of such Qualified Trustee or for any Liens
     on the Collateral arising from, through or under such Qualified Trustee in
     its individual capacity, and that so far as any Qualified Trustee,
     individually or personally is concerned, each Lender, each Borrower and the
     Agent and any Person claiming by, through or under such Persons shall look
     solely, except as provided above, to the Trust Estates (and, to the extent
     any Lender, Borrower or Agent has an interest therein, any liability
     insurance proceeds), for the performance of any obligation under this
     Credit Agreement and the other Loan Documents. The term "Trustee" as used
     in this Section 11.9(c) shall include any Qualified Trustee succeeding a
     Qualified Trustee, as trustee under a Trust Agreement. Any obligation of
     any Holdings Subsidiary Trust hereunder or under the other Loan Documents
     may be performed by a Beneficial Owner, and any such performance shall not
     be construed as revocation of the trust created by any Trust Agreement.

          11.10. Severability. If any provision of this Agreement or the other
Loan Documents shall be determined to be illegal or invalid as to one or more of
the parties hereto, then such provision shall remain in effect with respect to
all parties, if any, as to whom such provision is neither illegal nor invalid,
and in any event all other provisions hereof shall remain effective and binding
on the parties hereto.

          11.11. Entire Agreement. This Agreement, together with the other Loan
Documents, constitutes the entire agreement among the parties with respect to
the subject matter hereof and supersedes all previous proposals, negotiations,
representations, and other communications between or among the parties, both
oral and written, with respect thereto.

          11.12. Payments. All principal, interest, and other amounts to be paid
by any Borrower under this Agreement and the other Loan Documents shall be paid
to the Agent at the Principal Office in Dollars and in immediately available
funds, without setoff, deduction or counterclaim. Subject to the definition of
"Interest Period" herein, whenever any payment under this Agreement or any other
Loan Document shall be stated to be due on a day that is not a Business Day,
such payment may be made on the next succeeding Business Day, and such extension
of time in such case shall be included in the computation of interest and fees,
as applicable, and as the case may be.

          11.13. Confidentiality. The Agent and each Lender (each, a "Lending
Party") agrees to keep confidential any information furnished or made available
to it by Holdings, Irish Holdings or any Affiliate of Holdings or Irish Holdings
pursuant to or in connection with this


                                       77



Agreement or the other Loan Documents; provided that nothing herein shall
prevent any Lending Party from disclosing such information (a) to any other
