description of the Company, the Agent or such Lender against the Guarantor, in
any currency, whether arising hereunder, under the Purchase Agreement, the RLSA,

Guarantor promptly of any such set-off and the application made by the Company,
the Agent or such Lender; provided, that the failure to give such notice shall
not affect the validity of such set-off and application. The rights of the
Company, the Agent and each Lender under this section are in addition to other
rights and remedies (including, without limitation, other rights of set-off)
which the Company, the Agent or such Lender may have.

or right of offset held by the Company for the payment of the Seller
Obligations, nor shall the Guarantor seek or be entitled to seek any
contribution or reimbursement from the Seller in respect of payments made by the
Guarantor hereunder, until all amounts owing to the Company by the Seller on
account of the Seller Obligations are paid in full and the Purchase Agreement is
terminated. If any amount shall be paid to the Guarantor on account of such
subrogation rights at any time when all of the Seller Obligations shall not have
been paid in full, such amount shall be held by the Guarantor in trust for the
Company, segregated from other funds of the Guarantor, and shall, forthwith upon
receipt by the Guarantor, be turned over to the Company in the exact form

account of such subrogation rights at any time when all of the Servicer
Obligations shall not have been paid in full, such amount shall be held by the
Guarantor in trust for the Agent and the Lenders, segregated from other funds of
the Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned
over to the Agent in the exact form received by the Guarantor (duly indorsed by
the Guarantor to the Agent, if required), to be applied against the Servicer
Obligations, whether matured or unmatured, in such order as the Agent may
determine.

          5. Amendments, etc. with Respect to the Obligations; Waiver of Rights.

          (a) 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
Seller Obligations made by the Company may be rescinded by such party and any of
the Seller Obligations continued, and the Seller 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 Company, and the Purchase
Agreement and the other Transaction Documents and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Company may deem advisable from time to
time, and any collateral security, guarantee or right of offset at any time held
by the Company for the payment of the Seller Obligations may be sold, exchanged,
waived, surrendered or released. The Company shall not have any obligation to
protect, secure, perfect or insure any Lien at any time held by it as security
for the Seller Obligations or for this Guarantee or any property subject
thereto. When making any demand hereunder against the Guarantor, the Company
may, but shall be under no obligation to, make a similar demand on the Seller or
any other guarantor, and any failure by the Company to make any such demand or
to collect any payments from the Seller or any such other guarantor or any
release of the Seller of such other guarantor shall not relieve the Guarantor in
respect of which a demand or collection is not made of its obligations or
liabilities hereunder, and shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of the Company against the Guarantor.
For the purposes hereof "demand" shall include the commencement and continuance
of any legal proceedings.

          (b) 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
Servicer Obligations made by the Agent or any Lender may be rescinded by such
party and any of the Servicer Obligations continued, and the Servicer
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 Agent or such Lender, and the RLSA and the other Transaction Documents and
any other documents executed and delivered in connection therewith may be
amended, modified, supplemented or terminated, in whole or in part, as the Agent
(or the Required Lenders or all the Lenders, 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 Agent or any Lender for the payment of the
Servicer Obligations may be sold, exchanged, waived, surrendered or released.
Neither the Agent nor any Lender shall have any obligation to protect, secure,
perfect or insure any Lien at any time held by it as security for the Servicer
Obligations or for this Guarantee or any property subject thereto. When making
any demand hereunder against the Guarantor, the Agent and the Lenders may, but
shall be under no obligation to, make a similar demand on the Servicer or any
other guarantor, and any failure by the Agent or any Lender to make any such
demand or to collect any payments from the Servicer or any such other guarantor
or any release of the Servicer or such other guarantor shall not relieve the
Guarantor in respect of which a demand or collection is not made of its
obligations or liabilities hereunder, and shall not

                                                                               6

impair or affect the rights and remedies, express or implied, or as a matter of
law, of the Agent or the Lenders against the Guarantor. For the purposes hereof
"demand" shall include the commencement and continuance of any legal
proceedings.

          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 Company, the Agent or any
Lender 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, or renewed, extended, amended or waived, in reliance upon this
Guarantee; and all dealings between the Seller, the Servicer and the Guarantor,
on the one hand, and the Company, the Agent and the Lenders, on the other hand,
likewise shall 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 or the Guarantor with respect to any of the Obligations.
The Guarantor understands and agrees that this Guarantee shall be construed as a
continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity, regularity or enforceability of the Purchase Agreement, the
RLSA or any other Transaction Document, any of the Obligations or any other
collateral security therefor or guarantee or right of offset with respect
thereto at any time or from time to time held by the Company, the Agent or any
Lender, (b) any defense, set-off or counterclaim (other than a defense of
payment or performance) which may at any time be available to or be asserted by
the Seller, the Servicer or any other Person against the Company, the Agent or
any Lender or (c) any other circumstance whatsoever (with or without notice to
or knowledge of the Seller, the Servicer or the Guarantor) which constitutes, or
might be construed to constitute, an equitable or legal discharge of the Seller
or the Servicer for the Obligations, or of the Guarantor under this Guarantee,
in bankruptcy or in any other instance. When pursuing its rights and remedies
hereunder against the Guarantor, the Company, the Agent or any Lender may, but
shall be under no obligation to, pursue such rights and remedies as it may have
against the Seller, the Servicer 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 Company, the Agent or any Lender to pursue such
other rights or remedies or to collect any payments from the Seller, the
Servicer 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, Servicer or any such other Person or 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 Company, the Agent or
any Lender 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 Company, the Agent or any Lender upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Seller, the Servicer or of the
Guarantor, 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
or the Guarantor or any substantial part of its property, or otherwise, all as
though such payments had not been made.

     costs between them, and each shall bear its fair share of such expenses;

          12. Counterparts. This Guarantee may be executed by the Guarantor on
any number of separate counterparts, and all of said counterparts taken together
shall be deemed to constitute one and the same instrument. A set of the
counterparts of this Guarantee signed by the Guarantor shall be lodged with the
Company and the Agent. Delivery of an executed counterpart of a signature page
to this Guarantee by facsimile shall be effective as delivery of a manually

          13. 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.

          14. Integration. This Guarantee represents the agreement of the
Guarantor with respect to the subject matter hereof and there are no promises or
representations by the Company, the Agent or any Lender relative to the subject
matter hereof not reflected herein.

(except by a written instrument pursuant to paragraph 15(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced 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
Company, the Agent or any Lender 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 Company, the Agent or any
Lender of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy that the Company, the Agent or any
Lender would otherwise have on any future occasion.

          (c) The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

          17. Successors and Assigns. This Guarantee shall be binding upon the
successors and assigns of the Guarantor and shall inure to the benefit of the
Company, the Agent, the Lenders and their successors and assigns. The Guarantor
acknowledges that the Company shall assign all of its rights hereunder to the
Agent for the benefit of the Lenders. The Guarantor consents to such assignment
and agrees that the Agent and the Lenders shall be entitled to enforce the terms
of this Guarantee and the rights (including, without limitation, the right of
the Agent to grant or withhold any consent or waiver or give any notice) of the
Company directly against the Guarantor, whether or not an Event of Default has
occurred and that no consent, waiver or notice given hereunder by the Company
shall be effective unless the Agent has given its written consent thereto. The
Guarantor further agrees that, in respect of its obligations hereunder, it will
act at the direction of and in accordance with all requests and instructions
from the Agent until all the Obligations are paid and performed in full and the
Lender shall have no further obligation to make any additional Loans and the
RLSA has been terminated.

          18. Governing Law; Jurisdiction; Consent to Service of Process. (a)
This Guarantee shall be governed by, and construed and interpreted in accordance
with, the law of the State of New York.

of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Guarantee, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such Federal court. The
Guarantor agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Guarantee shall affect any
right that the Company, the Agent or any Lender may otherwise have to bring any
action or proceeding relating to this Guarantee against the Guarantor or its
properties in the courts of any jurisdiction.

          (c) The Guarantor hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Guarantee in any court referred to
in paragraph (b) of this section. The Guarantor hereby

irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

          (d) The Guarantor irrevocably consents to service of process in the
manner provided for notices in Section 11. Nothing in this Guarantee will affect
the right of any party to this Guarantee to serve process in any other manner
permitted by law.

EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN
ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
GUARANTEE OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,
