         2. ABSOLUTE GUARANTY OF ALL GUARANTIED OBLIGATIONS. Guarantor

All assets and property of Guarantor shall be subject to recourse if Guarantor

paid and performed pursuant to the Repurchase Documents.

         3. NATURE AND SCOPE OF LIABILITY. Guarantor's liability under this
Guaranty is primary and not secondary. Guarantor's liability under this Guaranty
shall be in the full amount of all Guarantied Obligations, including any
interest, default interest, costs and fees payable by Seller under the
Repurchase Documents, including any of the foregoing that would have accrued
under the Repurchase Documents but for any Insolvency Proceeding.

         4. CHANGES IN REPURCHASE DOCUMENTS. Without notice to, or consent by,
Guarantor, and in the Buyer Agent's sole and absolute discretion and without
prejudice to the Buyer Agent or in any way limiting or reducing Guarantor's
liability under this Guaranty, but subject to the terms of the Repurchase
Agreement, the Buyer Agent, on behalf of the Buyers, may: (a) grant extensions
of time, renewals or other indulgences or modifications to Seller or any other
party under any of the Repurchase Document(s), (b) change, amend, or modify any
Repurchase Document(s), (c) authorize the sale, exchange, release or
subordination of any Security, (d) accept or reject additional Security in
accordance with the terms of the Repurchase Agreement, (e) discharge or release
any party or parties liable under the Repurchase Documents, (f) foreclose or

accordance with the terms of the Repurchase Agreement, (g) accept or make
compositions or other arrangements or file or refrain from filing a claim in any
Insolvency Proceeding, (h) make loans to Seller in such amount(s) and at such
time(s) as the Buyer Agent may determine, (i) credit payments in such manner and
order of priority as the Buyer Agent may determine in its discretion, provided
that such credits shall be consistent with the requirements of the Repurchase
Agreement and (j) otherwise deal with Seller and any other party related to the
Repurchase Transactions or any Security as the Buyer Agent may determine in its
sole and absolute discretion. Without limiting the generality of the foregoing,
Guarantor's liability under this Guaranty shall continue even if the Buyer Agent
alters any obligations under the Repurchase Documents in any respect or any
Buyer's, the Buyer Agent's or Guarantor's remedies or rights against Seller are
in any way impaired or suspended without Guarantor's consent. If the Buyer Agent
performs any of the actions described in this paragraph, then Guarantor's
liability shall continue in full force and effect even if the Buyer Agent's
actions impair, diminish or eliminate Guarantor's subrogation, contribution, or
reimbursement rights (if any) against Seller.

         5. CERTAIN FINANCIAL COVENANTS. Guarantor shall satisfy with respect to
itself each of the following financial covenants, as determined quarterly on a
consolidated basis in conformity with GAAP as set forth in the financial
statements of Guarantor delivered pursuant to Section 15 hereof:

         5.1 Maintenance of Tangible Net Worth. Tangible Net Worth at the end of
each fiscal quarter shall not be less than the sum of (i) $400,000,000, plus,
(ii) an amount equal to 75% of any Equity Proceeds;


                                      -6-



         5.2 Maintenance of Ratio of Total Recourse Indebtedness to Tangible Net
Worth. The ratio of Total Recourse Indebtedness to Tangible Net Worth (the
"Tangible Net Worth Ratio") at the end of each fiscal quarter shall not be
greater than 3.0:1.0;

         5.3 Minimum DSCR. DSCR at the end of each fiscal quarter shall not be
less than 1.20:1.00; and

         5.4 Maintenance of Liquidity. The sum of (i) Cash, plus, (ii)
unencumbered and unpledged marketable securities plus, (iii) the Unfunded Margin
Amount at the end of each fiscal quarter shall not be less than $10,000,000;

         provided, that compliance with clauses 5.1 through 5.4 above shall be
determined by excluding the assets and liabilities of variable interest entities
required to be consolidated under FIN 46R and without giving any effect to any
changes in or in the interpretation of FAS 140 after the date hereof.

         6. NATURE OF GUARANTY. Guarantor's liability under this Guaranty is a
guaranty of payment and performance of the Guarantied Obligations, and is not a
guaranty of collection or collectability. Guarantor's liability under this
Guaranty is not conditioned or contingent upon the genuineness, validity,
regularity or enforceability of any of the Repurchase Documents. Guarantor's
liability under this Guaranty is a continuing, absolute, and unconditional
obligation under any and all circumstances whatsoever (except as expressly
stated, if at all, in this Guaranty), without regard to the validity, regularity
or enforceability of any of the Guarantied Obligations. Guarantor acknowledges
that Guarantor is fully obligated under this Guaranty even if Seller had no
liability at the time of execution of the Repurchase Documents or later ceases
to be liable under any Repurchase Document, whether pursuant to Insolvency
Proceedings or otherwise. Guarantor shall not be entitled to claim, and
irrevocably covenants not to raise or assert, any defenses against the
Guarantied Obligations that would or might be available to Seller, other than
actual payment and performance of all Guarantied Obligations in full in
accordance with their terms. Guarantor waives any right to compel the Buyer
Agent to proceed first against Seller or any Security before proceeding against
Guarantor. Guarantor agrees that if any of the Guarantied Obligations are or
become void or unenforceable (because of inadequate consideration, lack of
capacity, Insolvency Proceedings, or for any other reason), then Guarantor's
liability under this Guaranty shall continue in full force with respect to all
Guarantied Obligations as if they were and continued to be legally enforceable,
all in accordance with their terms before giving effect to the Insolvency
Proceedings. Guarantor also recognizes and acknowledges that its liability under
this Guaranty may be more extensive in amount and more burdensome than that of
Seller. Guarantor waives any defense that might otherwise be available to
Guarantor based on the proposition that a guarantor's liability cannot exceed
the liability of the principal. Guarantor intends to be fully liable under the
Guarantied Obligations regardless of the scope of Seller's liability thereunder.
Without limiting the generality of the foregoing, if the Guarantied Obligations
are "nonrecourse" as to Seller or Seller's liability for the Guarantied
Obligations is otherwise limited in some way, Guarantor nevertheless intends to
be fully liable, to the full extent of all of Guarantor's assets, with respect
to all the Guarantied Obligations, even though Seller's liability for the
Guarantied Obligations may be more limited in scope or less burdensome.
Guarantor waives any defenses to this Guaranty arising or purportedly arising
from the manner in which any Buyer or the Buyer Agent disburses the


                                      -7-



Repurchase Transactions to Seller or otherwise, or any waiver of the terms of
any Repurchase Document by the Buyer Agent or other failure of the Buyer Agent
to require full compliance with the Repurchase Documents. Guarantor's liability
under this Guaranty shall continue until all sums due under the Repurchase
Documents have been paid in full and all other performance required under the
Repurchase Documents has been rendered in full, except as expressly provided
otherwise (if at all) in this Guaranty. Guarantor's liability under this
Guaranty shall not be limited or affected in any way by any impairment or any
diminution or loss of value of any Security whether caused by (a) hazardous
substances, (b) the Buyer Agent's failure to perfect a security interest in any
Security, (c) any disability or other defense(s) of Seller, (d) any acts or
omissions of the Buyers or the Buyer Agent; or (e) any breach by Seller of any
representation or warranty contained in any Repurchase Document.

         7. WAIVERS OF RIGHTS AND DEFENSES. Guarantor waives any right to
require the Buyer Agent or any Buyer to (a) proceed against Seller, (b) proceed
against or exhaust any Security, or (c) pursue any other right or remedy for
Guarantor's benefit. Guarantor agrees that the Buyer Agent may proceed against
Guarantor with respect to the Guarantied Obligations without taking any actions
against Seller and without proceeding against or exhausting any Security.
Guarantor agrees that the Buyer Agent may unqualifiedly exercise in its sole
discretion (or may waive or release, intentionally or unintentionally) any or
all rights and remedies available to it against Seller without impairing the
Buyer Agent's rights and remedies in enforcing this Guaranty, under which
Guarantor's liabilities shall remain independent and unconditional. Guarantor
agrees and acknowledges that the Buyer Agent's exercise (or waiver or release)
of certain of such rights or remedies may affect or eliminate Guarantor's right
of subrogation or recovery against Seller (if any) and that Guarantor may incur
a partially or totally nonreimbursible liability in performing under this
Guaranty. Guarantor has assumed the risk of any such loss of subrogation rights,
even if caused by the Buyer Agent's acts or omissions. If the Buyer Agent's
enforcement of rights and remedies, or the manner thereof, limits or precludes
Guarantor from exercising any right of subrogation that might otherwise exist,
then the foregoing shall not in any way limit the Buyer Agent's rights to
enforce this Guaranty. Without limiting the generality of any other waivers in
this Guaranty, Guarantor expressly waives any statutory or other right that
Guarantor might otherwise have to: (i) limit Guarantor's liability after a
nonjudicial foreclosure sale conducted in accordance with the terms of the
Repurchase Agreement and applicable law to the difference between the Guarantied
Obligations and the fair market value of the property or interests sold at such
nonjudicial foreclosure sale or to any other extent, (ii) otherwise limit the
Buyer Agent's right to recover a deficiency judgment after any foreclosure sale
conducted in accordance with the terms of the Repurchase Agreement and
applicable law, or (iii) require the Buyer Agent to exhaust its Security before
the Buyer Agent may obtain, for the benefit of the Buyers, a personal judgment
for any deficiency. Notwithstanding anything in the Repurchase Agreement to the
contrary, any proceeds of a foreclosure or similar sale shall be applied first
to any obligations of Seller that also constitute Guarantied Obligations within
the meaning of this Guaranty. Guarantor acknowledges and agrees that any
nonrecourse or exculpation provided for in any Repurchase Document, or any other
provision of a Repurchase Document limiting the Buyer Agent's recourse to
specific Security or limiting the Buyer Agent's right to enforce a deficiency
judgment against Seller or any other person, shall have absolutely no
application to Guarantor's liability under this Guaranty.


                                      -8-



         8. ADDITIONAL WAIVERS. Guarantor waives diligence and all demands,
protests, presentments and notices of every kind or nature, including notices of
protest, dishonor, nonpayment, acceptance of this Guaranty and the creation,
renewal, extension, modification or accrual of any of the Guarantied
Obligations. Guarantor further waives the right to plead any and all statutes of
limitations as a defense to Guarantor's liability under this Guaranty or the
enforcement of this Guaranty. No failure or delay on the Buyer Agent's part in
exercising any power, right or privilege under this Guaranty shall impair or
waive any such power, right or privilege.

         9. NO DUTY TO PROVE LOSS. To the extent that Guarantor at any time
incurs any liability under this Guaranty, Guarantor shall immediately pay the
Buyer Agent (to be applied on account of the Guarantied Obligations) the amount
provided for in this Guaranty, without any requirement that the Buyer Agent
demonstrate that the Buyer Agent or any Buyer has currently suffered any loss or
that the Buyer Agent or any Buyer has otherwise exercised (to any degree) or
exhausted any of the Buyer Agent's or Buyers' rights or remedies with respect to
Seller or any Security.

         10. FULL KNOWLEDGE. Guarantor acknowledges, represents, and warrants
that Guarantor has had a full and adequate opportunity to review the Repurchase
Documents, the transactions contemplated by the Repurchase Documents, and all
underlying facts relating to such transactions. Guarantor represents and
warrants that Guarantor fully understands: (a) the remedies the Buyer Agent
and/or the Buyers may pursue against Seller and/or Guarantor in the event of a
default under the Repurchase Documents, (b) the value (if any) and character of
any Security and (c) Seller's financial condition and ability to perform under
the Repurchase Documents. Guarantor agrees to keep itself fully informed
regarding all aspects of the foregoing and the performance of Seller's
obligations to the Buyer Agent and the Buyers. Neither Buyer Agent nor any Buyer
has a duty, whether now or in the future, to disclose to Guarantor any
information pertaining to Seller, the Repurchase Transactions or any Security.
If at any time provided for in the Repurchase Documents, Guarantor agrees and
acknowledges that an Insolvency Proceeding affecting Guarantor, or other actions
or events relating to Guarantor (including Guarantor's change in financial
position), as set forth in the Repurchase Documents, may be event(s) of default
under the Repurchase Documents.

         11. REPRESENTATIONS AND WARRANTIES. Guarantor acknowledges, represents,
and warrants as follows, and acknowledges that the Buyer Agent is relying upon
the following acknowledgments, representations, and warranties by Guarantor in
making the Repurchase Transactions:

         11.1 Due Authorization. This Guaranty has been duly authorized,
executed, and delivered by Guarantor, and is a legally valid and binding

         11.2 No Conflict. The execution, delivery, and performance of this
Guaranty will not violate any provision of any law, regulation, judgment, order,

                                      -9-



security agreement, lease, contract or other agreement, instrument or
undertaking to which Guarantor is a party or that purports to bind Guarantor or
any of Guarantor's property or assets.

         11.3 No Third Party Consent Required. No consent of any person
(including creditors or partners, members, stockholders or other owners of
Guarantor) is required in connection with Guarantor's execution of this Guaranty
or performance of Guarantor's obligations under this Guaranty (other than
consents that have been obtained). Guarantor's execution of, and obligations
under, this Guaranty are not contingent upon any consent, license, permit,
approval or authorization of, exemption by, notice or report to or registration,
filing or declaration with, any governmental authority, bureau or agency,
whether local, state, federal or foreign.

         11.4 Authority and Execution. Guarantor has the necessary corporate
power and authority to execute, deliver and perform its obligations under this
Guaranty.

         11.5 No Representations by the Buyer Agent nor the Buyers. Guarantor

assurance by the Buyer Agent or the Buyers.

         12. REIMBURSEMENT AND SUBROGATION RIGHTS. Except to the extent that the
Buyer Agent notifies Guarantor to the contrary in writing from time to time:

         12.1 General Deferral of Reimbursement. Guarantor waives any right to
be reimbursed by Seller for any payment(s) made by Guarantor on account of the
Guarantied Obligations, unless and until all Guarantied Obligations have been
paid in full and all periods within which such payments may be set aside or
invalidated have expired. Guarantor acknowledges that Guarantor has received
adequate consideration for execution of this Guaranty by virtue of the Buyers'
entering into the Repurchase Transactions (which benefits Guarantor, as an owner
or principal of Seller) and Guarantor does not require or expect, and is not
entitled to, any other right of reimbursement against Seller as consideration
for this Guaranty.

         12.2 Deferral of Subrogation and Contribution. Guarantor agrees it
shall have no right of subrogation against Seller, the Buyers or the Buyer Agent
and no right of subrogation against any Security unless and until: (a) all
amounts due under the Repurchase Documents have been paid in full and all other
performance required under the Repurchase Documents has been rendered in full to
the Buyer Agent and the Buyers; and (b) all periods within which such payment
and performance may be set aside or invalidated have expired (such deferral of
Guarantor's subrogation and contribution rights, the "Subrogation Deferral").

         12.3 Effect of Invalidation. To the extent that a court of competent
jurisdiction determines that Guarantor's Subrogation Deferral is void or
voidable for any reason, Guarantor agrees, notwithstanding any acts or omissions
by the Buyers or the Buyer Agent, that Guarantor's rights of subrogation against
Seller, the Buyer Agent and Guarantor's right of subrogation against any
Security shall at all times be junior and subordinate to the Buyer Agent's
rights against Seller and to the Buyer Agent's right, title, and interest in
such Security.

         13. CLAIMS IN INSOLVENCY PROCEEDING. Guarantor shall not file any claim
in any Insolvency Proceeding affecting Seller unless Guarantor simultaneously
assigns


                                      -10-



and transfers such claim to the Buyer Agent, without consideration, pursuant to
documentation fully satisfactory to the Buyer Agent. Guarantor shall
automatically be deemed to have assigned and transferred such claim to the Buyer
Agent whether or not Guarantor executes documentation to such effect. By
executing this Guaranty, Guarantor hereby authorizes the Buyer Agent (and grants
the Buyer Agent a power of attorney coupled with an interest, and hence
irrevocable) to execute and file such assignment and transfer documentation on
Guarantor's behalf. the Buyer Agent shall have the sole right to vote, receive
distributions on and exercise all other rights with respect to any such claim;
provided, however, that if and when the Guarantied Obligations have been paid in
full, the Buyer Agent shall release to Guarantor any further payments received
on account of any such claim.

         14. BUYER'S DISGORGEMENT OF PAYMENTS. Upon payment of all or any
portion of the Guarantied Obligations, Guarantor's obligations under this
Guaranty shall continue and remain in full force and effect if all or any part
of such payment is, pursuant to any Insolvency Proceeding or otherwise, avoided
or recovered directly or indirectly from the Buyer Agent as a preference,
fraudulent transfer, or otherwise irrespective of (a) any notice of revocation
given by Guarantor prior to such avoidance or recovery or (b) payment in full of
the Repurchase Transactions. Guarantor's liability under this Guaranty shall
continue until all periods have expired within which the Buyer Agent could (on
account of Insolvency Proceedings, whether or not then pending, affecting Seller
or any other person) be required to return, repay, or disgorge any amount paid
at any time on account of the Guarantied Obligations.

         15. FINANCIAL INFORMATION. Within ninety days after the end of each
fiscal year of Guarantor and within forty-five days after the end of each of the
first three fiscal quarters, Guarantor shall deliver to the Buyer Agent the
financial statements of Guarantor (audited for the annual financial statements
and unaudited for the financial statements of the first three fiscal quarters),
together with an officer's certificate addressed to the Buyer Agent certifying
that, as of the end of such fiscal quarter or fiscal year, as applicable,
Guarantor was in compliance with each of the financial covenants contained in
Section 5 of this Guaranty and showing in reasonable detail the calculations
demonstrating such compliance.

         16. CONSENT TO JURISDICTION. Guarantor agrees that any proceeding to
enforce this Guaranty may be brought in any state or federal court located in
the State of New York. By executing this Guaranty, Guarantor irrevocably accepts
and submits to the nonexclusive jurisdiction of each of the aforesaid courts,
generally and unconditionally with respect to any such proceeding.

         17. MERGER; NO CONDITIONS; AMENDMENTS. This Guaranty and documents
referred to herein contain the entire agreement among the parties with respect
to the matters set forth in this Guaranty. This Guaranty supersedes all prior
agreements among the parties with respect to the matters set forth in this
Guaranty. No course of prior dealings among the parties, no usage of trade, and
no parol or extrinsic evidence of any nature shall be used to supplement,
modify, or vary any terms of this Guaranty. This Guaranty is unconditional.
There are no unsatisfied conditions to the full effectiveness of this Guaranty.
No terms or provisions of this Guaranty may be changed, waived, revoked, or
amended without the written agreement of the parties hereto. If any provision of
this Guaranty is determined to be unenforceable, then all other provisions of
this Guaranty shall remain fully effective.


                                      -11-



         18. GOVERNING LAW; ENFORCEMENT. This Guaranty shall be governed and
construed in accordance with the internal laws of the State of New York (without
regard to conflict of laws principles), notwithstanding the location of any
Security. Guarantor acknowledges that any restrictions, limitations and
prohibitions set forth in New York Real Property Actions and Proceedings Law
Sections 1301 and 1371 that would or might otherwise limit or establish
conditions to the Buyer Agent's recovery of a judgment against Guarantor if the
Security were located in the State of New York shall have absolutely no
application to the Buyer Agent's enforcement of this Guaranty as against
Guarantor, except to the extent that real property Security is located within
the State of New York. Guarantor acknowledges that this Guaranty is an
"instrument for the payment of money only," within the meaning of New York Civil
Practice Law and Rules Section 3213.

         19. FURTHER ASSURANCES. Guarantor shall execute and deliver such
further documents, and perform such further acts, as the Buyer Agent may
reasonably request to achieve the intent of the parties as expressed in this
Guaranty, provided, in each case, that any such documentation is consistent with
this Guaranty and with the Repurchase Documents.

         20. WAIVER OF TRIAL BY JURY. GUARANTOR WAIVES TRIAL BY JURY IN ANY
ACTION OR PROCEEDING ARISING FROM OR RELATING TO THIS GUARANTY OR THE REPURCHASE
DOCUMENTS OR ANY OBLIGATION(S) OF GUARANTOR HEREUNDER OR UNDER THE REPURCHASE
DOCUMENTS.

         21. MISCELLANEOUS.

         21.1 Assignability. the Buyer Agent may assign this Guaranty (in whole
or in part) together with any one or more of the Repurchase Documents to any
Person permitted under the Repurchase Agreement, without in any way affecting
Guarantor's or Seller's liability. In connection with any such assignment,
Guarantor shall deliver such documentation as the Buyer Agent shall reasonably
request. This Guaranty shall benefit the Buyer Agent and its successors and
permitted assigns and shall bind Guarantor and its heirs, executors,
administrators and successors. Guarantor may not assign this Guaranty, in whole
or in part.

         21.2 Notices. All notices, consents, approvals and requests required or
permitted hereunder shall be given in writing and shall be effective for all
purposes if hand delivered or sent by (i) hand delivery, with proof of attempted
delivery, (ii) certified or registered United States mail, postage prepaid,
(iii) expedited prepaid delivery service, either commercial or United States

comply with the technical requirements for notice under this Section may elect

         21.3 Interpretation. The word "include" and its variants shall be
interpreted in each case as if followed by the words "without limitation."

         21.4 Counterparts. This Guaranty may be executed in counterparts, each
of which so executed shall be deemed to be an original, but all of such
counterparts shall together constitute but one and the same instrument.

         22. BUSINESS PURPOSES. Guarantor acknowledges that this Guaranty,
although executed in Guarantor's individual capacity, is executed and delivered
for business and commercial purposes, and not for personal, family, household,

entitled to, and does not require the benefits of, any rights, protections, or
disclosures that would or may be required if this Guaranty were given for
personal, family, household, consumer, or agricultural purposes. Guarantor
acknowledges that none of Guarantor's obligation(s) under this Guaranty
constitute(s) a "debt" within the meaning of the United States Fair Debt
Collection Practices Act, 15 U.S.C. ss. 1692a(5), and accordingly compliance
with the requirements of such act is not required if the Buyer Agent (directly
or acting through its counsel) makes any demand or commences any action to
enforce this Guaranty.

         23. NO THIRD-PARTY BENEFICIARIES. This Guaranty is executed and
delivered for the benefit of the Buyer Agent, for the benefit of the Buyers, and
