and power of, the Borrower under this Agreement and each other Operative
Agreement and any other document contemplated hereby and thereby to which the

been named as the Borrower herein and therein.  No such consolidation or merger,
or sale, conveyance, transfer or lease of all or substantially all of the assets

                                              --------
     Borrower is subject to the reporting provisions of the Securities Exchange
     Act of 1934, a copy of the Borrower's quarterly report on Form 10-Q will
     satisfy this requirement;

              (ii)  within 120 days after the end of each fiscal year of the
     Borrower, a copy of the annual report for such year for the Borrower or the
     affiliated group of which the Borrower is a member (on a consolidated
     basis, if applicable) and a balance sheet of the Borrower and its
     subsidiaries (if any) as of the end of such fiscal year and related
     statements of income, shareholder's equity and cash flows of the Borrower
     for such fiscal year, in comparative form with the preceding fiscal year,
     in each case certified by independent certified public accountants of
     national standing as having been prepared in accordance with generally
     accepted accounting principles in the United States, provided that so long
                                                          --------
     as the Borrower is subject to the reporting provisions of the Securities
     Exchange Act of 1934, a copy of the Borrower's annual report on Form 10-K
     will satisfy this requirement; and

              (iii) from time to time, such other non-confidential financial
     information as the Lender may reasonably request.

          (f) Filing of Documents.  Borrower, at its sole cost and expense, will

               LENDER'S REPRESENTATIONS, WARRANTIES AND COVENANTS

          Section 5.01   Representations, Warranties and Covenants of Lender.
                         ---------------------------------------------------

          (a)    Representations and Warranties.  The Lender represents and
                 ------------------------------
warrants that, as of each Funding Date (unless any such representation and
warranty is specifically made as of an earlier date, in which case the Lender
represents and warrants as of such earlier date):

                 (i)   it is a corporation duly organized and validly existing
     and is in good standing under the laws of State of Rhode Island and it has
     full corporate power, authority and legal right to carry on its present
     business and operations, to own or lease its properties and to enter into
     and carry out the transactions contemplated by this Agreement and the other
     Operative Agreements to which it is a party;

                 (ii)  the Operative Agreements to which it is party have been
     duly executed and delivered by the Lender and constitute the legal, valid
     and binding obligations of the Lender enforceable against it in accordance
     with their terms except as such enforceability may be limited by
     bankruptcy, insolvency, or other similar laws or general equitable
     principles; and

                 (iii) the funds to be used by the Lender to fund each Loan to
     the Borrower pursuant to the terms hereof do not constitute assets (within
     the meaning of ERISA and any applicable rules and regulations) of an ERISA
     Plan.

          (b)    Assignment of Loan. At any time after the Funding Date of Loan
                 ------------------
B and subject to satisfaction of the conditions set forth in this Section
5.01(b), the Lender may assign, convey or otherwise transfer to any Affiliate of
Lender or to a single institutional investor or an Affiliate of an institutional
investor all (but not less than all) of the Loan, provided that (i) the Lender
                                                  --------
gives the Borrower at least 10 days' notice of such assignment, conveyance or
other transfer, and (ii) the transferee shall make a representation to the
effect that the funds to be used by the transferee to acquire the Loan do not
constitute the assets of an ERISA Plan.  No assignment, conveyance or transfer
by the Lender of the Loan shall increase the amount of the liability of the
Borrower hereunder or under any other Operative Agreements over the amount of
liability the Borrower would have incurred had such assignment, conveyance or
transfer not occurred.

          Section 5.02   The Borrower's Right of Quiet Enjoyment.
                         ---------------------------------------
Notwithstanding any other provision of any of the Operative Agreements, Lender
covenants that at any time while any Obligations are outstanding, so long as no
Event of Default shall have occurred and be continuing and the Lender has not
commenced the exercise of remedies set forth in Section 9.01 and Section 5.02 of
the Security Agreement, Lender or any Person claiming by,  through or under
Lender will not take or cause to be taken any action contrary to the Borrower's
rights hereunder, including, without limitation, its rights to possession, use
and quiet enjoyment of the Engines, provided that
                                    --------

                                       14

nothing contained herein shall affect any of the rights of the Lender under
Section 9.01 or 5.02 of the Security Agreement upon the occurrence and during
the continuance of an Event of Default.

          Section 5.03   Survival of Representations, Warranties and Covenants.
                         -----------------------------------------------------
Representations, warranties and covenants of the Lender provided for in this
Article 5, and its obligations under any and all of them, shall survive the
making and repayment of each Loan and the expiration or other termination of
this Agreement and the other Operative Agreements.

          Section 7.01   Generally.
                         ---------

          (a)  Indemnity.  The Borrower agrees to assume liability for, and also
               ---------
agrees to indemnify each Indemnitee against and agrees to protect, defend, save
and keep harmless each Indemnitee from and against and in respect of, and will
pay on an After Tax Basis, any and all liabilities, obligations, losses,
damages, settlements, penalties, claims, actions, suits, costs, disbursements
and expenses, demands or judgments (including reasonable legal fees and
expenses) of every kind and nature, whether or not any of the transactions
contemplated by this Agreement are consummated and whether arising before, on or
after either Funding Date (individually, an "Expense," collectively,
"Expenses"), which may be imposed on, incurred or suffered by or asserted
against any Indemnitee, in any way relating to, arising out of or in connection
with, any one or more of the following:

               (i)   any Operative Agreement or any transaction contemplated
     thereby;

     abandonment, redelivery or other disposition, repair or testing of the

     other Person whatsoever, whether or not such operation, possession, use,
     non-use, maintenance, storage, overhaul, delivery, non-delivery, control,
     condition, alteration, modification, addition, improvement, replacement,
     substitution, return, abandonment, redelivery or other disposition, repair
     or testing is in compliance with the terms hereof and of the Security
     Agreement, including, without limitation, claims for death, personal injury
     or property damage or other loss or harm to any Person whatsoever,
     including, without limitation, any passengers, shippers or other Persons
     wherever located, claims or penalty relating to any laws, rules or
     regulations, including, without limitation,

<PAGE>

     environmental control, noise and pollution laws, rules or regulation and
     any Liens in respect of the Engines or any Part;

               (iii)  the manufacture, design, sale, return, purchase,
     acceptance, nonacceptance, rejection, delivery, non-delivery, condition,
     repair, modification, servicing, rebuilding, registration, reregistration,
     deregistration, ownership, financing, import, export, performance, non-
     performance, pooling, lease, sublease, transfer, merchantability, fitness
     for use, alteration, substitution or replacement of any Engine, or Part or
     other transfer of use or possession, or other disposition of the Engines or
     any Part including, without limitation, latent and other defects, whether
     or not discoverable, tort liability, whether or not arising out of the
     negligence of any Indemnitee (whether active, passive or imputed and
     including strict or absolute liability without fault), and any claims for
     patent, trademark or copyright infringement;

               (iv)   any breach of or failure to perform or observe, or any
     other non-compliance with, any condition, covenant or agreement to be
     performed, or other obligations of the Borrower under any of the Operative
     Agreements, or the falsity or inaccuracy of any representation or warranty
     of the Borrower in any of the Operative Agreements or the occurrence of any
     Default or Event of Default; and

               (v)    the enforcement of the terms of the Operative Agreements
     (including this Section 7.01(a)).

          (b)  Exceptions.  The indemnity provided for in Section 7.01(a) shall
               ----------
not extend to any Expense to the extent it:

               (i)    is attributable to the willful misconduct or gross
     negligence of any Indemnitee (other than gross negligence or willful
     misconduct imputed to such person by reason of its interest in the Engines
     or any Part or any transaction documents);

               (ii)   is, except to the extent fairly attributable to acts or
     events occurring prior thereto, attributable to acts or events (other than
     the performance by Borrower of its obligations pursuant to the terms of the
     Operative Agreements) which occur after full repayment of the Loan by the
     Borrower;

               (iii)  is, other than as expressly provided herein or in the
     other Operative Agreements, a Tax or loss of a Tax benefit;

               (iv)   is a cost or expense expressly required to be paid by an
     Indemnitee or its permitted transferees (and not by the Borrower) pursuant
     to this Agreement or any other Operative Agreement and for which the
     Borrower is not otherwise obligated to reimburse an Indemnitee pursuant to
     the terms of this Agreement or such other Operative Agreement;

                                       16
<PAGE>

               (v)    is attributable to the incorrectness or breach by an
     Indemnitee of its representations or warranties, under any of the Operative
     Agreements;

               (vi)   is attributable to the failure by an Indemnitee to perform
     any of its obligations under any of the Operative Agreements except to the
     extent such failure was caused by a breach by Borrower of any
     representation or warranty or by any failure of Borrower to perform any
     obligation under an Operative Agreement;

               (vii)  is attributable to the offer or sale of any interest in
     the Aircraft or the Loan or any similar interest (including an offer or
     sale resulting from bankruptcy or other proceedings for the relief of
     debtors in which an Indemnitee is the debtor), unless in each case such
     offer or sale shall occur pursuant to the exercise of remedies hereunder
     and under any other Operative Agreement;

               (viii) is an Expense relating to, resulting from, arising out of
     or in connection with a "prohibited transaction" within the meaning of
     Section 406 of ERISA or Section 4975(c)(1) of the Code; and

               (ix)   constitutes an Indemnitee's  overhead.

          (c)  Non-Parties.  If an Indemnitee is not a party to this Agreement,
               -----------
in order to be entitled to the benefit of this Article 7, such Indemnitee shall
comply with the terms of this Article 7 in connection with its making any claim
for indemnification hereunder.

          Section 7.02   Notice and Payment.  Each Indemnitee shall give prompt
                         ------------------
written notice to the Borrower of any liability as to which a Responsible
Officer of such Indemnitee has actual knowledge, for which the Borrower is, or
may be, liable under this Article 7; provided, however, that failure to give
                                     --------  -------
such notice shall not terminate any of the rights of an Indemnitee under this
Article 7 and shall not release Borrower from any of its obligations to
indemnify such Indemnitee hereunder, except to the extent that such failure
adversely affects any applicable defense or counterclaim, otherwise increases
the amount the Borrower would have been liable for in the absence of such
failure to provide such notice or adversely affects the ability of Borrower's
insurers to defend such claim.

          Section 7.03   Defense of Claims.  Pursuant to the terms hereof, the
                         -----------------
Borrower or its insurers shall have the right (in each such case at the
Borrower's sole expense) to investigate, defend (and control the defense of) any
such claim for which indemnification is sought pursuant to this Article 7 and
each Indemnitee shall reasonably cooperate with the Borrower and its insurers
with respect thereto, provided that, such right of the Borrower shall be subject
                      -------- ----
to Borrower having acknowledged in writing its obligation to indemnify the
Indemnitee in respect of such claim if the defense of such claim is unsuccessful
(unless and to the extent it is determined during any related proceedings that
any of the exclusions set forth in Section 7.01(b) are applicable to such
claim); provided further that, without limiting the right of the Borrower's
        -------- ------- ----
insurers to assume and control the

                                       17
<PAGE>

defense of or to compromise, any such claim, the Borrower shall not be entitled
to assume and control the defense of or compromise any such claim (A) during the
continuance of any Event of Default, (B) if an actual or potential material
conflict of interest exists making it advisable in the good faith opinion of
such Indemnitee (on the basis of prevailing standards of professional
responsibility) for such Indemnitee to be represented by separate counsel or if
such proceeding involves the potential imposition of criminal (or any non-de
minimis risk of civil) liability on such Indemnitee (and, in any such instance,
Borrower shall pay the reasonable fees and expenses of Lender's counsel) or (C)
if such proceeding will involve any non-de minimis risk of the sale, forfeiture
or loss of, or the creation of any Lien (other than Permitted Liens) on the
Engines (unless the Borrower posts a bond or other security reasonably
acceptable in form and substance to such Indemnitee) or involve any risk of
criminal liability to such Indemnitee. Subject to the immediately foregoing
sentence, where the Borrower or the insurers under a policy of insurance
maintained by the Borrower undertake the defense of an Indemnitee with respect
to such a claim, no additional legal fees or expenses of such Indemnitee in
connection with the defense of such claim shall be indemnified hereunder unless
the fees or expenses were incurred at the written request of the Borrower or
such insurers; provided, that, subject to the rights of Borrower's insurers to
               --------  ----
assume and control the defense of or to compromise (as provided herein), any
such claim, any counsel selected by Borrower in connection with any defense
shall be reasonably acceptable to the Lender. Subject to the requirement of any
policy of insurance applicable to a claim, an Indemnitee may participate at its
own expense at any judicial proceeding controlled by the Borrower or its
insurers pursuant to the preceding provisions, to the extent that such party's
participation does not, in the reasonable opinion of the independent counsel
appointed by the Borrower or its insurers to conduct such proceedings, interfere
with the defense of such claim; and such participation shall not constitute a
waiver of the indemnification provided in this Section 7.03. No Indemnitee shall
enter into any settlement or other compromise with respect to any claim
described in this Section 7.03 without the prior written consent of the Borrower
(which consent shall not be unreasonably withheld or delayed) and its insurers,
unless such Indemnitee waives its right to be indemnified under this Article 7
with respect to such claim. Subject to the rights of Borrower's insurers to
assume and control the defense of or to compromise, any such claim, the Borrower
shall not enter into any settlement or compromise relating to any claims against
the Lessor without consent of Lender (which consent shall not be unreasonably
withheld or delayed); provided that, Borrower's insurers may not enter into any
                      -------------
such settlement or compromise without Lender's consent unless a release of all
related claims against the Lender (and any other Indemnitee) shall be obtained
in connection with such settlement or compromise.

          Section 7.04   Insured Claims.  Notwithstanding any other provision of
                         --------------
this Article 7 to the contrary, in the case of any Expense indemnified by the
Borrower hereunder which is covered by a policy of insurance maintained by the
Borrower (or a Permitted Lessee) pursuant to Section 4.05 of the Security
Agreement or otherwise, it shall be a condition of such indemnity with respect
to any particular Indemnitee that such Indemnitee shall reasonably cooperate
with the insurers in the exercise of their rights to investigate, defend or
compromise such claim as may be required to retain the benefits of such
insurance with respect to such claim.

                                       18
<PAGE>

          Section 7.05   Subrogation.  To the extent that an Expense indemnified
                         -----------
by the Borrower under this Article 7 is in fact paid in full by the Borrower
and/or an insurer under a policy of insurance maintained by the Borrower, the
Borrower and/or such insurer as the case may be shall be subrogated to the
extent of such payment to the rights and remedies of the Indemnitee on whose
behalf such Expense was paid with respect to the transaction or event giving
rise to such Expense (other than the rights and remedies in respect of insurance
policies maintained by such Indemnitee). So long as no Event of Default has
occurred and is continuing, should an Indemnitee receive any refund, in whole or
in part, with respect to any Expense paid in full by the Borrower hereunder, it
shall promptly pay over the amount refunded (but not an amount in excess of the
amount Borrower and/or such insurer has paid to such Indemnitee in respect of
such Expense) to the Borrower.

          Section 7.06   Information.  Subject to Section 7.04, Borrower will
                         -----------
provide the relevant Indemnitee with such information, not within the control of
such Indemnitee, as is in Borrower's control or is reasonably available to
Borrower, which such Indemnitee may reasonably request, and will otherwise
cooperate with such Indemnitee, so as to enable such Indemnitee to fulfill its
obligations under Section 7.03 and to control or participate in any proceeding
to the extent permitted by Section 7.03.  The Indemnitee shall supply Borrower
with such information, not within the control of Borrower, as is in such
Indemnitee's control or is reasonably available to such Indemnitee, which
Borrower may reasonably request to control or participate in any proceeding to
the extent permitted by Section 7.03.

          Section 7.07   Survival of Obligations.  The indemnities and
                         -----------------------
agreements of the Borrower provided for in this Article 7 shall survive the
expiration or other termination of this Agreement and the other Operative
Agreements.

          Section 7.08   Effect of Other Indemnities.  The Borrower's
                         ---------------------------
obligations under this Article 7 shall be those of a primary obligor whether or
not the Person indemnified shall also be indemnified with respect to the same
matter under the terms of this Agreement, or any other document or instrument or
by any other Person and regardless of any other rights that Borrower may have
against such Indemnitee pursuant to any Operative Agreement or otherwise, and
the Person seeking indemnification from the Borrower pursuant to any provision
of this Agreement may proceed directly against the Borrower without first
seeking to enforce any other right of indemnification.

          Section 7.09   Waiver of Certain Claims.  The Borrower hereby waives
                         ------------------------
and releases any Expense now or hereafter existing against any Indemnitee
arising out of death or personal injury to personnel of the Borrower, loss or
damage to property of the Borrower, or the loss of use of any property of the
Borrower, which results from or arises out of the condition, use or operation of
the Engines, including, without limitation, any latent or patent defect whether
or not discoverable.

          Section 8.01   Events of Default.  The following events shall
                         -----------------
constitute Events of Default and each such Event of Default shall be deemed to
exist and continue so long as, but only so long as, it shall not have been
remedied:

          (a)  Borrower shall fail to make any payment of (i) principal of or
interest on the Loan, whether by acceleration or otherwise, when due and such
failure shall continue for a period of ten (10) days; or (ii) any other amount
required to be paid to Lender pursuant to any of the Borrower Documents within
20 days after receipt by the Borrower of a written demand therefor from the
Lender;

          (b)  The Borrower shall fail to procure and maintain any insurance
required pursuant to Section 4.05 of the Security Agreement or such insurance
shall be cancelled or lapse; provided that such lapse or cancellation shall not
                             --------
constitute an Event of Default until the earlier of 30 days after receipt by the
Lender of notice of such lapse or cancellation or the date that the lapse or
cancellation is effective as to the Lender;

          (c)  The Borrower shall use the Engines after having received notice
that the public liability insurance required by Section 4.05(a) of the Security
Agreement has lapsed or has been cancelled (For the avoidance of doubt, the
event specified in this Section 8.01(c) is an additional event constituting an
Event of Default hereunder and is separate and independent from the event
specified in Section 8.01(b) above.);

          (d)  The Borrower shall fail to perform or observe any other covenant
or condition to be performed or observed by it hereunder or under any other
Operative Agreement, and such failure shall continue unremedied for a period of
30 days after delivery of notice of such failure from the Lender to the
Borrower, unless such failure is curable and the Borrower shall, after the
delivery of such notice, be diligently proceeding to correct such failure and
shall in fact correct such failure 135 days after delivery of such notice;
provided that, such additional 105 period shall not apply to any such failure
-------- ----
under Section 4.01(b)(x) or 4.06 of the Security Agreement or Section 4.02(c)
hereof;

          (e)  Any representation or warranty made by the Borrower herein or in
any other Operative Agreement or in any certificate required to be delivered by
the Borrower pursuant thereto shall prove to have been incorrect in any material
respect when made and shall remain material at the time in question and shall
not be remedied within 30 days after notice thereof has been given to the
Borrower by the Lender, unless such incorrectness is curable and Borrower shall,
after delivery of such notice, be diligently proceeding to correct such failure
and shall in fact correct such failure 135 days after the delivery of such
notice;

          (f)  The Borrower shall consent to the appointment of or taking
possession by a receiver, assignee, custodian, sequestrator, trustee or
liquidator (or other similar official) of itself or of a substantial part of its
property, or the Borrower shall admit in writing its inability to pay its debts
generally as they come due (as provided in 11 U.S.C. (S)303(h)(1)), or shall
make a general assignment for the benefit of its creditors, or the Borrower
shall file a voluntary petition in bankruptcy or a voluntary petition or answer
seeking liquidation, reorganization or other relief with respect to itself or
