       (viii)    Any duty on the part of the Owner Trustee to disclose to the 
     Guarantor any facts that the Owner Trustee may now or hereafter know 
     about FHF or the Properties, regardless of whether the Owner Trustee has 
     reason to believe that any such facts materially increase the risk 
     beyond that which the Guarantor intends to assume or has reason to 
     believe that such facts are unknown to the Guarantor or has a reasonable 
     opportunity to communicate such facts to the Guarantor, it being 
     understood and agreed that the Guarantor is fully responsible for being 
     and keeping informed of the financial condition of FHF, of the condition 
     of the Properties, and of any and all circumstances bearing on the risk 
     that liability may be incurred by the Guarantor hereunder;

         (ix)    Any lack of notice of disposition or of manner of

     Operative Agreements, in whole or in part;

       (xiii)    Any sale or assignment by FHF of any Property, or any 
     portion thereof or interest therein, whether or not consented to by the 
     Owner Trustee and any release by the Owner Trustee of any Property;

        (xiv)    Any invalidity, irregularity or unenforceability, in whole 
     or in part, of any one or more of the Operative Agreements;

         (xv)    Any lack of commercial reasonableness in dealing with any 
     Property;

        (xvi)    Any deficiencies in any Property or any deficiency in the 
     ability of the Owner Trustee to collect or to obtain performance from 
     any Persons or entities now or hereafter liable for the payment and 
     performance of any of the FHF Obligations;

       (xvii)    An assertion or claim that the automatic stay provided by 11

     proceeding of FHF) or any other stay provided under any other debtor 
     relief law (whether statutory, common law, case law or otherwise) of any 
     jurisdiction whatsoever, now or hereafter in effect, which may be or 
     become applicable, shall operate or be interpreted to stay, interdict, 
     condition, reduce or inhibit the ability of the Owner Trustee, to 
     enforce any of its rights, whether now or hereafter acquired, which the 
     Owner Trustee may have against the Guarantor or the Property;

      (xviii)    Any modification of the Operative Agreements or any 
     obligation of FHF relating to the FHF Obligations by operation of law or 
     by action of any court, whether pursuant to the Bankruptcy Reform Act of 
     1978, as amended, or any other debtor relief law (whether statutory, 
     common law, case law or otherwise) of any jurisdiction whatsoever, now or 
     hereafter in effect, or otherwise;

        (xix)    Any change in the composition of FHF;


                                     - 12 -



         (xx)   The release of FHF or of any other Person or entity from 
    performance or observance of any of the agreements, covenants, terms or 
    conditions contained in any agreements, documents or instruments; and 

         (xxi)  Without limiting the generality of the foregoing, any rights 
    and benefits which might otherwise be available to any guarantor under 
    California Civil Code Sections 2809, 2810, 2815, 2819, 2822, 2839, 2845 
    through 2847, 2848, 2849, 2850, 2899 and 3433, and California Code of Civil
    Procedure Sections 580a, 580b, 580d and 726, and any successor sections to 
    such sections of the Civil Code and Code of Civil Procedures.


    The Guarantor expressly acknowledges and agrees to the foregoing waivers 
in subclause (xxi) and the Guarantor further understands (with respect to 
California law) that: (A) Section 580d of the California Code of Civil 
Procedure generally prohibits a deficiency judgment against a borrower after 
a non-judicial foreclosure; (B) Guarantor's subrogation rights may be 
destroyed by a non-judicial foreclosure under the Mortgage Instrument 
(because the Guarantor may not be able to pursue FHF for a deficiency 
judgment by reason of the application of Section 580d of the California Code 
of Civil Procedure); (C) under UNION BANK V. GRADSKY, 265 Cal. App. 2nd 40 
(1968), a lender may be estopped from pursuing a guarantor for a deficiency 
judgment after a non-judicial foreclosure (on the theory that a guarantor 
should be exonerated if a lender elects a remedy that eliminates the 
guarantor's subrogation rights) absent an explicit waiver, and (D) GRADSKY, 
SUPRA PROVIDES THAT THE GUARANTOR MAY WAIVE THAT DEFENSE, THUS ALLOWING A 
LENDER TO PURSUE THE GUARANTOR ON ITS GUARANTEE EVEN THOUGH THE GUARANTOR 
WILL NOT BE ABLE TO PURSUE FHF BECAUSE THE GUARANTOR'S SUBROGATION RIGHTS 
WILL HAVE BEEN DESTROYED. Without limitation on the generality of the other 
waivers contained in this Guaranty Agreement, the Guarantor hereby waives all 
rights and defenses arising out of an election of remedies by the creditor, 
even though that election of remedies, such as a nonjudicial foreclosure with 
respect to security for a guaranteed obligation, has destroyed the 
Guarantor's rights of subrogation and reimbursement against the principal by 
the operation of Section 580d of the Code of Civil Procedure of California or 
otherwise.

    (b)  Without limitation to the provisions of the preceding subparagraph 
(a) or any other term or provision of this Guaranty Agreement, the Guarantor 
specifically acknowledges and agrees and consents to (i) the conveyance by 
the Owner Trustee from time to time of all or any part of the Property in 
accordance with the terms of the Operative Agreements, as determined by Owner 
Trustee in its sole discretion, without notice to or consent of the 
Guarantor, and (ii) the non-recourse provisions of Sections 14.10 of the 
Participation Agreement.

Acquisition and is in an aggregate principal amount of not in excess of 
$50,000,000 and (II) not more than 90 days have elapsed since the 
consummation of such Acquisition), if any, specified in the relevant document 
on the date of such failure if the effect of such failure, event or condition

beneficiary or beneficiaries of such Indebtedness (or a trustee or agent on 
behalf of such holder or holders or beneficiary or beneficiaries) to cause 
such Indebtedness to be declared to be due and


                                     - 14 -



payable prior to its stated maturity, or such Contingent Obligation to become

this clause if (I) such Indebtedness or Contingent Obligation was assumed in 
connection with an Acquisition and is in an aggregate principal amount of not 
in excess of $50,000,000 and (II) not more than 90 days have elapsed since 
the consummation of such Acquisition), if any, specified in the relevant 
document on the date of such failure if the effect of such failure, event or 
condition is to cause, or to permit the holder or holders of such 
Indebtedness of beneficiary or beneficiaries of such Indebtedness (or a 
trustee or agent on behalf of such holder or holders or beneficiary or 
beneficiaries) to cause such Indebtedness to be declared to be due and 
payable prior to its stated maturity, or such Contingent Obligation to become

Guarantor's or any Significant Subsidiary's properties, and any such

incidents or conditions, of $20,000,000 or more (or, in the case of the 
litigation described on SCHEDULE 8.01(i) hereto, $25,000,000 or more) and 
the same shall remain unsatisfied, unvacated and unstayed pending appeal for 
a period of 60 days after the entry thereof or the Guarantor shall not settle

     in any such event, the Owner Trustee may by notice to the Guarantor 
     declare its obligations under the Operative Agreements to be 
     terminated, whereupon the same shall forthwith terminate, and the Owner 
     Trustee shall have the right to exercise its remedies in accordance with 
     Article XVII of the Lease and the Owner Trustee may, without the 
     necessity of further action, call upon the Guarantor for prompt payment 
     and/or performance.

          The Guarantor agrees that, as between the Guarantor, on the one 
     hand, and the Owner Trustee, on the other hand, the FHF Obligations may 
     be declared to be forthwith due and payable as provided in the Lease 
     (and shall be deemed to have become automatically due and payable in the 
     circumstances provided in the Lease) for purposes of Section 2.01 
     hereof, notwithstanding any stay, injunction or other prohibition 
     preventing such declaration (or such FHF Obligations from becoming 
     automatically due and payable) as against any other Person and that, in 
     the event of such declaration (or such FHF Obligations being deemed to 
     have become automatically due and payable), such FHF Obligations 
     (whether or not due and payable by any other Person) shall forthwith 
     become due and payable by the Guarantor for purposes of said
     Section 2.01.

     2.06  NO SUBROGATION; NO RECOURSE AGAINST OWNER TRUSTEE. Notwithstanding 
the satisfaction by the Guarantor of any liability of the Guarantor 
hereunder, the Guarantor shall not


                                     - 17 -



have any right of subrogation, contribution, reimbursement or indemnity 
whatsoever or any right of recourse to or with respect to the assets or 
property of FHF or to any Property. In connection with the foregoing, the 
Guarantor expressly waives any and all rights of subrogation to the Owner 
Trustee against FHF, and the Guarantor hereby waives any rights to enforce 
any remedy which the Owner Trustee may have against FHF and any right to 
participate in any Property. Further, the Guarantor shall have no right of 
recourse against the Owner Trustee by reason of any action that the Owner 
Trustee may take or omit to take under, and in accordance with, the 
provisions of this Guaranty Agreement or under the provisions of any of the 
Operative Agreements.

     2.07  CONTINUING GUARANTEE. The guarantee in this Section 2 is a 
continuing guarantee, and shall apply to all FHF Obligations whenever arising.


                                  ARTICLE III

                             [INTENTIONALLY OMITTED]

                                   ARTICLE IV

                     REPRESENTATIONS, WARRANTIES AND COVENANTS

     Reference is made to the representations and warranties contained in 
Article V of the Existing Credit Agreement (hereinafter referred to as the 
"INCORPORATED REPRESENTATIONS AND WARRANTIES") and the covenants contained in 
Article VI and Article VII of the Existing Credit Agreement (hereinafter 
referred to as the "INCORPORATED COVENANTS"). The Guarantor agrees with the 
Owner Trustee that the Incorporated Representations and Warranties and the 
Incorporated Covenants (and all other relevant provisions of the Existing 
Credit Agreement related thereto) are hereby incorporated by reference into 
this Guaranty Agreement to the same extent and with the same effect as if set 
forth fully herein, including without limitation any and all waivers, 
amendments, modifications or replacements of the Existing Credit Agreement or 
any term or provision of the Incorporated Representations and Warranties and 
the Incorporated Covenants occurring subsequent to the date of this Guaranty 
Agreement and the Guarantor further agrees that the Incorporated 
Representations and Warranties shall be deemed to be restated and made as of 
the date hereof and as of the date of each Requisition. In the event a waiver 
is grated under the Existing Credit Agreement or an amendment or modification 
is executed with respect to the Existing Credit Agreement, and such waiver, 
amendment and/or modification affects the Incorporated Representations and 
Warranties or the Incorporated Covenants, then such waiver, amendment or 
modification shall automatically be effective with respect to the 
Incorporated Representations and Warranties and the Incorporated Covenants as 
incorporated by reference into this Guaranty Agreement without further 
action. If any Lender is not a lender under the Existing Credit Agreement, 
Guarantor shall deliver to such Lender a copy of the waiver, amendment or 
modification affecting the Incorporated Representations or Warranties or the 
Incorporated


                                     - 18 -



Covenants. In the event of any replacement of the Existing Credit Agreement 
with a similar credit facility (the "NEW FACILITY") then, if each of 
the Lenders are lenders under the New Facility, the representations, 
warranties and covenants contained in the New Facility which correspond to 
the representations, warranties and covenants contained in Article V, Article 
VI and Article VII of the Existing Credit Agreement shall automatically become 
Incorporated Representations and Warranties and the Incorporated Covenants 
hereunder without further action. If one or more of the Lenders is not 
a lender under the New Facility, (i) the Guarantor shall deliver, or cause to 
be delivered, a copy of the executed New Facility to each of the Lenders on 
or prior to the effective date thereof and the Majority Lenders shall elect 
whether (i) the representations, warranties and covenants contained in the New 
Facility which correspond to the representations, warranties and covenants 
contained in Article IV and Article V of the Existing Credit Agreement shall 
become the Incorporated Representations and Warranties and the Incorporated 
Covenants hereunder or (ii) the representations, warranties and covenants 
contained in Article V, Article VI and Article VII of the Existing Credit 
Agreement immediately prior to such termination (as such may have been 
amended, modified, supplemented, restated and/or replaced from time to time 
prior to the termination of the Existing Credit Agreement) shall continue to 
be the Incorporated Representations and Warranties and the Incorporated 
Covenants hereunder. If the Existing Credit Agreement is terminated and not 
replaced, then the representations, warranties and covenants contained in 
Article V, Article VI and Article VII of the Existing Credit Agreement 
immediately prior to such termination (as such may have been amended, 
modified, supplemented, restated and/or replaced from time to time prior to 
such termination) shall continue to be the Incorporated Representations and 
Warranties and the Incorporated Covenants hereunder.

     5.03 NO WAIVER, REMEDIES CUMULATIVE. No failure or delay on the part of 
the Owner Trustee in exercising any right, power or privilege hereunder or 
under any other Guarantor Document and no course of dealing between the 
Guarantor and the Owner Trustee shall operate as a waiver thereof, nor shall 
any single or partial exercise of any right, power or privilege hereunder or 
under any other Guarantor Document preclude any other or further exercise 
thereof or the exercise of any other right, power or privilege hereunder or 
thereunder. The rights and remedies provided herein are cumulative and not 
exclusive of any rights or remedies which the Owner Trustee would otherwise 
have. No notice to or demand on the Guarantor in any case shall entitle the 
Guarantor to any other or further notice or demand in similar or other 
circumstances or constitute a waiver of the rights of the Owner Trustee to 
any other or further action in any circumstances without notice or demand.

     5.04 PAYMENT OF EXPENSES, ETC. The Guarantor agrees to:

          (a)  pay all reasonable out-of-pocket costs and expenses of the

     such costs and expenses of the Owner Trustee, the Agent, the Lenders and 
     the Holders in connection with enforcement of the Guarantor Documents 
     (including, without limitation, the reasonable fees and
