     (d) The Guarantor agrees that whenever, at any time, or from time to time,
it shall make any payment to the Managing Facility Agent or any Purchaser on
account of its liability hereunder, it will notify the Managing Facility Agent
and such Purchaser, if applicable, in writing that such payment is made under
this Guarantee for such purpose. No payment or payments made by the Seller, the
Servicer, RAC or any other Person or received or collected by the Managing
Facility Agent or any Purchaser from the Seller, the Servicer, RAC or any other
Person by virtue of any action or proceeding or any set-off or appropriation or
application, at any time or from time to time, in reduction of or in payment of
the Obligations shall be deemed to modify, reduce, release or otherwise affect
the liability of the Guarantor hereunder which shall, notwithstanding any such
payment or payments, continue until the Obligations are paid in full and the
Commitments are terminated. This Guarantee shall remain in full force and effect
until the Obligations are paid in full and the Commitments are terminated,
notwithstanding that from time to time prior thereto the Seller, the Servicer
and/or RAC may be free from any Obligations.

     (e) Notwithstanding anything herein to the contrary, the Guarantor, in lieu
of paying or depositing the amount required to repurchase any Purchased
Receivable pursuant to the Purchase Agreement or the Repurchase Agreement, may
purchase such Receivable directly from the Purchasers in accordance with the

     3. Right of Set-off. Upon the occurrence and continuance of a Rating Event

or (j) of the Purchase Agreement, the Managing Facility Agent and each Purchaser
are hereby irrevocably authorized at any time and from time to time without
notice to the Guarantor, any such notice being hereby waived by the Guarantor,
to set off and appropriate and apply any and all deposits (general or special,
time or demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by the Managing Facility Agent or such Purchaser to or for the credit or
the account of the Guarantor, or any part thereof in such amounts as the
Managing Facility Agent or such Purchaser may elect, on account of the
liabilities of the Guarantor hereunder and claims of every nature and
description of the Managing Facility Agent or any Purchaser against the
Guarantor, in any currency, whether arising hereunder, under the Purchase
Agreement or under the Repurchase Agreement, as the Managing Facility Agent or
such Purchaser may elect, whether or not the Managing Facility Agent or such
Purchaser has made any demand for payment and although such liabilities and
claims may be contingent or unmatured. The Managing Facility Agent and such
Purchaser shall notify the Guarantor promptly of any such set-off made by it and
the application made by it of the proceeds thereof, provided that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of the Managing Facility Agent and each Purchaser under this
paragraph are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which the Managing Facility Agent or such
Purchaser may have.

                                       5

     4. No Subrogation, Contribution, Reimbursement or Indemnity.
Notwithstanding anything to the contrary in this Guarantee, the Guarantor hereby
irrevocably waives all rights which may have arisen in connection with this
Guarantee to be subrogated to any of the rights (whether contractual, under
Title 11 of the United States Code, including Section 509 thereof, under common
law or otherwise) of the Managing Facility Agent and the Purchasers against the
Seller, the Servicer or RAC or against any right of offset of the Managing
Facility Agent and the Purchasers with respect to the Obligations. The Guarantor
hereby further irrevocably waives all contractual, common law, statutory or
other rights of reimbursement, contribution, exoneration or indemnity (or any
similar right) from or against the Seller, the Servicer, RAC or any other Person
which may have arisen in connection with this Guarantee. So long as any
Obligations remain outstanding, if any amount shall be paid by or on behalf of
the Seller, the Servicer or RAC to the Guarantor on account of any of the rights
waived in this paragraph, such amount shall be held by the Guarantor in trust,
segregated from other funds of the Guarantor, and shall, forthwith upon receipt
by the Guarantor (duly endorsed by the Guarantor to the Managing Facility Agent,
if required), be applied against the Obligations, whether matured or unmatured,
in such order as the Managing Facility Agent may determine. The provisions of
this paragraph shall survive the termination of the Purchase Agreement and the
Repurchase Agreement and the payment in full of the Obligations; provided that
the foregoing waiver shall be of no force and effect 370 days following the
termination of the Purchase Agreement and the Repurchase Agreement and the
payment in full of the Obligations but only if during such 370-day period none
of the Seller, the Servicer, RAC or the Guarantor shall have commenced or have
commenced against it a bankruptcy proceeding under Title 11 of the United States
Code.

     5. Amendments, etc. with respect to the Obligations. The Guarantor shall
remain obligated hereunder notwithstanding that, without any reservation of
rights against the Guarantor, and without notice to or further assent by the
Guarantor, any demand for payment of any of the Obligations made by the Managing
Facility Agent or any Purchaser may be rescinded by the Managing Facility Agent
or such Purchaser, and any of the Obligations continued, and the Obligations, or
the liability of any other party upon or for any part thereof, or any collateral
security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Managing
Facility Agent or any Purchaser, and the Purchase Agreement, the Repurchase
Agreement, any other Purchase Document or any other documents executed and
delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Purchasers (or the Required Purchasers,
as the case may be) may deem advisable from time to time, and any collateral
security, guarantee or right of offset at any time held by the Managing Facility
Agent or any Purchaser for the payment of the Obligations may be sold,
exchanged, waived, surrendered or released. Neither the Managing Facility Agent
nor any Purchaser shall have any obligation to protect, secure, perfect or
insure any Lien at any time held by it as security for the Obligations or for
this Guarantee or any property subject thereto.
<PAGE>

                                       6

     6. Guarantee Absolute and Unconditional. The Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof of reliance by the Managing Facility Agent or any
Purchaser upon this Guarantee or acceptance of this Guarantee; the Obligations,
and any of them, shall conclusively be deemed to have been created, contracted
or incurred in reliance upon this Guarantee; and all dealings between the
Seller, the Servicer, RAC or the Guarantor, on the one hand, and the Managing
Facility Agent and the Purchasers, on the other, shall likewise be conclusively
presumed to have been had or consummated in reliance upon this Guarantee. The
Guarantor waives diligence, presentment, protest, demand for payment and notice
of default or nonpayment to or upon the Seller, the Servicer, RAC or the
Guarantor with respect to the Obligations. This Guarantee shall be construed as
a continuing, absolute and unconditional guarantee without regard to the
validity or enforceability of the Purchase Agreement, the Repurchase Agreement,
the Assignments, the FAA Assignments, the Foreign Assignments, the Bailment
Agreement or any other document or instrument executed in connection with any of
the foregoing documents, any of the Obligations or any collateral security
therefor or guarantee or right of offset with respect thereto at any time or
from time to time held by the Managing Facility Agent or any Purchaser, any
defense which relates, directly or indirectly, to the matters covered by the
representations and warranties set forth in Section 4 of the Purchase Agreement
or Section 8 of the Repurchase Agreement or set-off which in either case may at
any time be available to or be asserted by the Seller, the Servicer or RAC
against the Managing Facility Agent or any Purchaser, or any other circumstance
whatsoever (with or without notice to or knowledge of the Seller, the Servicer,
RAC or the Guarantor) which constitutes, or might be construed to constitute, an
equitable or legal discharge of the Seller, the Servicer or RAC for the
Obligations, or of the Guarantor under this Guarantee, in bankruptcy or in any
other instance; provided that this clause (c) shall not prevent the Guarantor
from being discharged from its obligations under this Guarantee pursuant to
confirmation of a plan of reorganization under Chapter 11 of the United States
Code in a case in which the Guarantor is the debtor. When the Managing Facility
Agent, or any Purchaser is pursuing its rights and remedies hereunder against
the Guarantor, the Managing Facility Agent or such Purchaser may, but shall be
under no obligation to, pursue such rights and remedies as it may have against
the Seller, the Servicer, RAC or any other Person or against any collateral
security or guarantee for the Obligations or any right of offset with respect
thereto, and any failure by the Managing Facility Agent or any Purchaser to
pursue such other rights or remedies or to collect any payments from the Seller,
the Servicer, RAC or any such other Person or to realize upon any such
collateral security or guarantee or to exercise any such right of offset, or any
release of the Seller, the Servicer, RAC or any such other Person or of any such
collateral security, guarantee or right of offset, shall not relieve the
Guarantor of any liability hereunder, and shall not impair or affect the rights
and remedies, whether express, implied or available as a matter of law, of the
Managing Facility Agent and the Purchasers against the Guarantor.

     7. Reinstatement. This Guarantee shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any of the Obligations is rescinded or must otherwise be restored or returned by
the Managing Facility Agent or any Purchaser upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Seller, the Servicer or RAC or
upon or as a result of the appointment of a receiver, intervenor or conservator
of, or trustee or similar officer for, the Seller, the Servicer, RAC or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

     any Persons whomsoever (other than of the Managing Facility Agent or any
     Purchaser).

(d)  Not convey, sell, lease, assign, transfer or otherwise dispose of all or
     substantially all the property, business or assets of the Guarantor to any
     Person or Persons unless such Person or Persons delivers a written
     assumption of the Guarantor's obligations under this Guarantee (which
     assumption shall not release the Guarantor hereunder) and a legal opinion
     with respect thereto, all satisfactory in form and substance to the
     Managing Facility Agent and its counsel.

(e)(i) Not issue, assume or guarantee any Debt on or after the date hereof, if
     such Debt is secured by a mortgage, pledge, security interest or lien (any
     mortgage, pledge, security interest or lien being hereinafter in this
     subsection 10(e) referred to as a "mortgage" or "mortgages") upon any
     Principal Property, or any shares of stock or indebtedness of any
     Subsidiary, whether now owned or hereafter acquired, without in any such
     case effectively providing, concurrently with the issuance, assumption or
     guarantee of any such Debt, that this Guarantee (together with, if the
     Guarantor shall so determine, any other indebtedness of or guaranteed by
     the Guarantor or such Subsidiary ranking equally with the Guarantor and
     then existing or thereafter created) shall be secured equally and ratably
     with (or prior to) such Debt; provided however, that the foregoing
     restriction shall not apply to:

     (A) mortgages on any Principal Property, shares of stock or indebtedness of
any corporation existing at the time such corporation becomes a Subsidiary;

     (B) mortgages on any Principal Property acquired, constructed or improved
by the Guarantor or any Subsidiary after the date hereof which are created or
assumed contemporaneously with, or within 90 days after, such acquisition,
construction or improvement to secure or provide for the payment of the purchase
price of such property or the cost of such construction or improvement incurred
after the date hereof, or, in addition to mortgages contemplated by clause (C)
below, mortgages on any Principal Property existing at the time of acquisition
thereof; provided, however, that in the case of any such acquisition,
construction or improvement the mortgage shall not apply to any property
theretofore owned by the Guarantor or any Subsidiary, other than, in the case of
any such construction or improvement, any theretofore unimproved real property
on which the property so constructed, or the improvement, is located;
<PAGE>

                                       11

     (C) mortgages on any Principal Property or shares of stock or indebtedness
acquired from a corporation which is merged with or into the Guarantor or a
Subsidiary;

     (D) mortgages to secure Debt of a Subsidiary to the Guarantor or to another
Subsidiary; and

     (E) any extension, renewal or replacement (or successive extensions,
renewals or replacements), in whole or in part, of any mortgage referred to in
the foregoing clauses (A) to (D) inclusive; provided, however, that the
principal amount of Debt secured thereby shall not exceed the principal amount
of Debt so secured at the time of such extension, renewal or replacement and
that such extension, renewal or replacement shall be applicable only to all or a
part of the property which secured the mortgage extended, renewed or replaced
(plus improvements on the property).

(ii) The Guarantor will not, nor will it permit any Subsidiary to merge or
     consolidate with another corporation, or sell all or substantially all of
     its assets to another corporation for a consideration other than the fair
     market value thereof which consideration shall consist of liquid assets
     (which shall have a fair market value readily determinable by an
     independent source), (x) unless, in the case of a merger or consolidation
     of the Guarantor or a sale by the Guarantor of substantially all of its
     assets, the successor or purchasing corporation, as applicable, has assumed
     all of the obligations of the Guarantor hereunder and (y) if such other
     corporation has outstanding obligations secured by a mortgage which, after
     such merger, consolidation or sale would extend to any of the assets owned
     by the Guarantor or such Subsidiary immediately prior to such merger,
     consolidation or sale unless, prior to such merger, consolidation or sale,
     the Guarantor or such Subsidiary shall have effectively provided that this
     Guarantee (together with, if the Guarantor or such Subsidiary shall so
     determine, any other Debt, indebtedness or liability issued, assumed or
     guaranteed by the Guarantor or such Subsidiary, whether then existing or
     thereafter created) shall be secured by a mortgage, the lien of which, upon
     completion of said merger, consolidation or sale, will rank prior to the
     lien of such mortgage of such other corporation on all assets owned by the
     Guarantor or such Subsidiary immediately prior to such merger,
     consolidation or sale, which, upon completion of such merger, consolidation
     or sale, will be subjected to the lien of such mortgage of such other
     corporation.

(iii) In the event that the Guarantor shall enter into any indenture or other
     agreement or instrument relating to the issuance of Debt (collectively,
     referred to herein as an "indenture") and the provisions of any such
     indenture with respect to restrictions on Liens permitted to be created or
     to exist on any of the Guarantor's property or the granting of equal and
     ratable security interests (collectively, the "Lien Provisions") are more
     restrictive on the Guarantor than this subsection 10(e), then without any
     action by any Person, the Lien Provisions shall be deemed to be
     incorporated by reference in the provisions of this subsection 10(e) with
     the Obligations under this Guarantee constituting the "Debt" for purposes
     of such Lien Provision.

                                       12

(f)  Not enter into any material transaction with any Affiliate (other than a
     Subsidiary of Raytheon), including, without limitation, any purchase, sale,
     lease or exchange of property or the rendering of any service, unless any
     such transaction is upon fair and reasonable terms no less favorable to the
     Guarantor or such Material Subsidiary, as the case may be, than it would
     obtain in a comparable arm's length transaction with a Person not an
     Affiliate.

(g)  Pay, discharge or otherwise satisfy at or before maturity or before they
     become delinquent, as the case may be, all obligations of whatever nature
     which are material to the business, operations, property or financial or
     other condition of the Guarantor and its consolidated Subsidiaries taken as
     a whole, except where the amount or validity thereof is currently being
     contested in good faith by appropriate proceedings and reserves in
     conformity with GAAP with respect thereto have been provided on the books
     of the Guarantor and its consolidated Subsidiaries taken as a whole.

(h)  Comply with all Contractual Obligations and Requirements of Law except to
     the extent that the failure to comply therewith could not, in the
     aggregate, reasonably be expected to have a material adverse effect on the
     business, operations, property or financial or other condition of the
     Guarantor and its consolidated Subsidiaries taken as a whole or on the
     ability of the Guarantor to perform its obligations hereunder.

(i)  Maintain with financially sound and reputable insurance companies insurance
     on all its property in at least such amounts and against at least such
     risks as are usually insured against in the same general area by companies
     engaged in the same or a similar business; and furnish to the Managing
     Facility Agent, upon written request of any Purchaser, a schedule of
     insurance then in force setting forth the type of coverage, the names of
     the insurance carriers, policy numbers, the amount and type of coverage and
     the term of each policy, together with a certificate or certificates of
     insurance.

(j)  Permit representatives of the Managing Facility Agent or any Purchaser to
     visit and inspect any of its properties and examine and make abstracts from
     any books and records of the Guarantor with respect to the transactions
     contemplated by the Purchase Documents at any reasonable time and as often
     as may reasonably be necessary and to discuss the business, operations,
     properties and financial and other condition of the Guarantor and its
     Material Subsidiaries with officers of the Guarantor having knowledge of
     such matters and with its independent certified public accountants;
     provided that any information, records and materials obtained by the
     Managing Facility Agent or any Purchaser pursuant to this paragraph 10(j)
     shall be used by the Managing Facility Agent or such Purchaser solely in
     connection with its participation in the transactions contemplated by the
     Purchase Documents (including pursuant to subsection 11.6(b) and (c) of the
     Purchase Agreement) and shall be treated as confidential by the Managing
     Facility Agent or such Purchaser in accordance with Section 11.22 of the
     Purchase Agreement.

(k)  Cause its short-term unsecured indebtedness to be rated by either or both
     S&P and Moody's and cause its long-term unsecured indebtedness to be rated
     by S&P, Moody's and Duff or any combination thereof.

                                       13

(l)  Within 45 days after the end of each of the first three fiscal quarters of
     each fiscal year of the Guarantor and within 90 days after the end of the
     fourth fiscal quarter of each fiscal year of the Guarantor, deliver to the
     Managing Facility Agent, with sufficient copies for each Purchaser, a
     certificate of the chief financial officer, treasurer or comparable officer
     of the Guarantor setting forth the Guarantor's Debt Ratio for the
     Guarantor's fiscal quarter ended prior to the date of such certificate and
     Interest Coverage Ratio for the Guarantor's four consecutive fiscal
     quarters ended prior to the date of such certificate, showing calculations
     therefor in reasonable detail and specifying whether a Trigger Amortization
     Event of the type specified in subsection 8.1(g) or (h) of the Purchase
     Agreement has occurred.

(m)  Cause RAC to maintain full and adequate product liability insurance with
     respect to each Financed Aircraft with financially sound and reputable
     insurance companies (which may include a program of product liability
     insurance maintained by an Affiliate of Raytheon, the sole business of
     which is providing insurance for Raytheon and its Affiliates).

     11. Severability. Any provision of this Guarantee which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     12. Paragraph Headings. The paragraph headings used in this Guarantee are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

     13. No Waiver; Cumulative Remedies. Neither the Managing Facility Agent nor
any Purchaser shall by any act (except by a written instrument pursuant to
paragraph 14 hereof), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any default or
Amortization Event, Ineligibility Event, Remittance Event, Discount Event or
Rating Event, or in any breach of any of the terms and conditions hereof. No
failure to exercise, nor any delay in exercising, on the part of the Managing
Facility Agent or any Purchaser, any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. A waiver by the Managing
Facility Agent or any Purchaser of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the
Managing Facility Agent or such Purchaser would otherwise have on any future
occasion. The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any rights or remedies
provided by law.

     14. Waivers and Amendments; Successors and Assigns. None of the terms or
provisions of this Guarantee may be waived, amended, supplemented or otherwise
modified except by a written instrument executed by the Guarantor and the
Managing Facility Agent in accordance with the Purchase Agreement. This
Guarantee shall be binding upon the successors and assigns of the Guarantor and
shall inure to the benefit of the Managing Facility Agent and the Purchasers and
their successors and assigns.

Guarantor shall not be under any obligation, or entitlement, to make any inquiry
respecting such authority.

or such Purchaser may have to claim or recover in any legal action or proceeding

damages; provided that the waiver contained in this paragraph 18 shall not
extend to any right to claim or recover from the Guarantor any special,
exemplary, punitive or consequential damages for which the Managing Facility
Agent or any Purchaser is liable to any Person (other than an Affiliate of the
Managing Facility Agent or such Purchaser).

     19. Acknowledgements. The Guarantor hereby acknowledges with respect to the
transactions contemplated by the Purchase Documents that:

(a)  it has been advised by counsel in the negotiation, execution and delivery
     of this Guarantee;

(b)  neither the Managing Facility Agent nor any Purchaser has any fiduciary
     relationship to the Guarantor or the Seller and the relationship between

     20. WAIVERS OF JURY TRIAL. THE GUARANTOR AND, BY THEIR ACCEPTANCE HEREOF,

     any thereof;

(b)  consents that any such action or proceeding may be brought in such courts

     claim the same;

(c)  agrees that service of process in any such action or proceeding may be
     effected by mailing a copy thereof by registered or certified mail (or any
     substantially similar form of mail), postage prepaid, to it at its address
     set forth below its signature hereto or at such other address of which the
     Managing Facility Agent shall have been notified pursuant hereto;

(d)  agrees that nothing herein shall affect the right to effect service of
     process in any other manner permitted by law or shall limit the right to
     sue in any other jurisdiction; and

(e)  waives, to the maximum extent not prohibited by law, any right it may have
     to claim or recover in any legal action or proceeding referred to in this
     subsection any special, exemplary, punitive or consequential damages.
