                       AMOUNT AND TERMS OF LENDERS' LOANS

        II.1 Tranche A Loans and Tranche B Loans.

        (a) Subject to the terms and conditions hereof and of the Participation
Agreement, each Tranche A Lender severally agrees to make loans (the "Tranche A
Loans") to the Lessor on the Refinancing Date for the purpose of enabling the
Lessor to repay Existing Indebtedness, in an aggregate principal amount of
$44,402,172.57. No amounts paid or prepaid with respect to any Tranche A Loan
may be reborrowed.

        (b) Subject to the terms and conditions hereof and of the Participation
Agreement, each Tranche B Lender severally agrees to make loans (the "Tranche B
Loans") to the Lessor on the Refinancing Date for the purpose of enabling the
Lessor to repay Existing Indebtedness, in an aggregate principal amount of
$6,954,557.16. No amounts paid or prepaid with respect to any Tranche B Loan may
be reborrowed.

        II.2 Borrowing Procedure. Upon receipt by each Lender of a Funding
Request from the Lessee in accordance with Section 3.4(a) of the Participation
Agreement, the Lessor shall be deemed to have requested a borrowing of Loans
from each Lender in an amount equal to such Lender's Commitment Percentage of
the aggregate Advance requested by such Funding Request. On the terms and
subject to the conditions of this Loan Agreement and the Participation Agreement
(including without limitation the satisfaction of the applicable conditions
precedent set forth in Article VI of the Participation Agreement), the Lenders
shall make Loans to the Lessor on the Funding Date set forth in such Funding
Request.

        II.3 [Reserved]

        II.4 Notes. The Loans made by each Lender shall be evidenced by a
promissory note of the Lessor, substantially in the form of Exhibit A, in the
case of Tranche A Loans (each, a "Tranche A Note"), or Exhibit B, in the case of
Tranche B Loans (each, a "Tranche B Note"), with appropriate insertions as to
payee, date and principal amount, payable to the order of such Lender and in a
principal amount equal to the initial Commitment of such Lender. Each Lender is
hereby authorized to record the date and amount of each Loan made by such
Lender, each continuation thereof, the date and amount of each payment or
prepayment of principal thereof and the length of each Interest Period with
respect thereto, on the schedule annexed to and constituting a part of its Note,
and any such recordation shall constitute prima facie evidence of the accuracy
of the information so recorded, provided that the failure to make any such
recordation or any error in such recordation shall not affect the Lessor's
obligations hereunder or under such Note. 



                                      -2-
   6
Each Note shall (i) be dated the date of the Refinancing Date, (ii) be stated to
mature on the Maturity Date and (iii) provide for the payment of interest in
accordance with this Loan Agreement.

        II.5 Prepayments.

        (a) Voluntary. The Lessor may at any time and from time to time prepay
the Loans, in whole or in part, without premium or penalty (subject to Section
13.10 of the Participation Agreement), upon at least four Business Days' written
notice to each Lender specifying the date and amount of prepayment and the
Property to which such Loans are allocable. If any such notice is given, the
amount specified in such notice shall be due and payable on the date specified
therein, together with any amounts payable pursuant to Article XIII (including
without limitation Section 13.10) of the Participation Agreement .

        (b) Mandatory. Notwithstanding the foregoing, all amounts payable by the
Lessee pursuant to Article XV, XVIII or XX of the Master Lease shall be used to
prepay the Loans and the Equity Amounts and shall be applied to the Loans and
the Equity Amounts in the manner set forth in Article IVA of the Participation
Agreement.

        II.6 Interest Rates and Payment Dates. (a) Each Loan shall bear interest
for each day during each Interest Period with respect thereto at a rate per
annum equal to the LIBO Rate (Reserve Adjusted) determined for such day plus the
Applicable A-Margin, in the case of Tranche A Loans, or the Applicable B-Margin,
in the case of Tranche B Loans.

        (a) If all or a portion of (i) the principal amount of any Loan, (ii)
any interest payable thereon or (iii) any other amount payable hereunder shall
not be paid when due (whether at the stated maturity, by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum which is
equal to the Overdue Rate.

        (b) Interest shall be payable in arrears on each Scheduled Payment Date,
provided that (i) interest accruing pursuant to clause (b) of this Section 2.6
shall be payable from time to time on demand and (ii) each prepayment of the
Loans shall be accompanied by accrued interest to the date of such prepayment on
the amount prepaid.

        II.7 Computation of Interest.

        (a) Interest on the Loans shall be calculated on the basis of a 365- (or
366-, as the case may be) day year for the actual days elapsed at all times that
interest is calculated by reference to the Alternate Base Rate, and interest
shall be calculated at all other times on the basis of a 360-day year for the
actual days elapsed. The Agent shall as soon as practicable


                                      -3-
   7
notify the Lessor and the Lenders of each determination of a LIBO Rate. Any
change in the interest rate on a Loan resulting from a change in the Alternate
Base Rate or the LIBOR Reserve Percentage shall become effective as of the
opening of business on the day on which such change becomes effective. The Agent
shall as soon as practicable notify the Lessor and the Lenders of the effective
date and the amount of each such change in interest rate.

        (b) Each determination of an interest rate by the Agent pursuant to any
provision of this Loan Agreement shall be conclusive and binding on the Lessor
and each Lender in the absence of manifest error. The Agent shall, at the
request of the Lessor, deliver to the Lessor a statement showing the quotations
used by the Agent in determining any interest rate pursuant to Section 2.7(a).

        II.8 Pro Rata Treatment and Payments. Each borrowing by the Lessor from
the Lenders hereunder shall be made pro rata among the Tranche A Lenders and
Tranche B Lenders according to the respective Commitment Percentage of each such
Lender. Except as otherwise provided in Article IVA of the Participation
Agreement, each payment (including each prepayment) by the Lessor on account of
principal of and interest on the Loans shall be made pro rata among the Tranche
A Lenders and Tranche B Lenders according to the respective outstanding
principal amounts of the Loans then held by each such Lender. Subject to Article
V, all payments (including prepayments) to be made by the Lessor hereunder and
under the Notes, whether on account of principal, interest or otherwise, shall
be made without setoff or counterclaim and shall be made by the Lessor to the
applicable Lender prior to 2:00 p.m., New York time, to such Lender's Payment
Office specified in Schedule IV to the Participation Agreement (or to such other
office as may be designated by such Lender from time to time in a written notice
to the Lessor) in funds consisting of lawful currency of the United States of
America which shall be immediately available on the scheduled date when such
payment is due, unless such scheduled date shall not be a Business Day, in which
case such payment shall be made on the next succeeding Business Day. Payments
received after 2:00 p.m., New York time, on the date due shall for the purpose
of Section 6.1 be deemed received on such day; provided, however, that for the
purposes of Section 2.7(b), such payments shall be deemed received on the next
succeeding Business Day and, unless the Lenders are otherwise able to invest or
employ such funds on the date received, subject to interest at the Overdue Rate
as provided in Section 2.7(b).

        VI.2 Remedies.

        (a) Upon the occurrence of any Loan Agreement Event of Default:

        (i) if such event is a Loan Agreement Event of Default specified in
clause (e) above or a Lease Event of Default specified in Section 16.1(g) or (h)
of the Master Lease, the Commitments of all Lenders shall automatically and
immediately terminate and Loans hereunder (with accrued interest thereon) and
all other amounts owing under this Loan Agreement and the Notes shall
immediately become due and payable, and

        (ii) if such event is any other Loan Agreement Event of Default, any or
all of the following actions may be taken: (w) Tranche A Lenders holding a
majority of the outstanding Tranche A Loans may, by notice to the Lessor,
declare the Tranche A Loan Commitments to be terminated forthwith, whereupon the
Tranche A Loan Commitments shall immediately terminate; (x) Tranche B Lenders
holding a majority of the outstanding Tranche B Loans may, by notice to the
Lessor, declare the Tranche B Loan Commitments to be terminated forthwith,
whereupon the Tranche B Loan Commitments shall immediately terminate, (y)
Tranche A Lenders holding a majority of the outstanding Tranche A Loans may, by
notice to the Lessor, declare all Tranche A Loans hereunder (with accrued
interest thereon) and all other amounts owing with respect to the Tranche A
Loans under this Loan Agreement and the Tranche A Notes to be due and payable
forthwith, whereupon all Loans shall immediately become due and payable and (z)
Tranche B Lenders holding a majority of the outstanding Tranche B Loans may, by
notice to the Lessor, declare all Tranche B Loans hereunder (with accrued
interest thereon) and all other amounts owing with respect to the Tranche B
Loans under this Loan Agreement and the Tranche B Notes to be due and payable
forthwith, whereupon all Loans shall immediately become due and payable (any of
the foregoing occurrences or actions referred to in clause (i) above or this
clause (ii), an "Acceleration"). Except as expressly provided above in this
Article VI, presentment, demand, protest and all other notices of any kind are
hereby expressly waived.

        (b) Upon the occurrence of any Loan Agreement Event of Default and at
any time thereafter so long as any Loan Agreement Event of Default shall be
continuing, the Tranche B Lenders may, at their sole discretion, and the Agent
shall, upon the written instructions of Tranche A Lenders holding a majority of
the outstanding Tranche A Loans, exercise any or all of the rights and powers
and pursue any and all of the remedies available to it hereunder and (subject to
the terms thereof) under the other Loan Documents and the Leases and shall have
any and all rights 



                                      -7-
   11
and remedies available under the Uniform Commercial Code or any provision of
law.

        (c) Upon the occurrence of any Loan Agreement Event of Default and at
any time thereafter so long as any Loan Agreement Event of Default shall be
continuing, the Lenders may proceed to protect and enforce this Loan Agreement,
the Notes, the Master Lease and the other Operative Documents by suit or suits
or proceedings in equity, at law or in bankruptcy, and whether for the specific
performance of any covenant or agreement herein contained or in execution or aid
of any power herein granted, or for foreclosure hereunder, or for the
appointment of a receiver or receivers for the Properties or any Property or for
the recovery of judgment for the indebtedness secured thereby or for the
enforcement of any other proper, legal or equitable remedy available under
Applicable Law.

        (d) The Lessor shall be liable for any and all accrued and unpaid
amounts due hereunder before, after or during the exercise of any of the
foregoing remedies, including all reasonable legal fees and other reasonable
costs and expenses incurred by the Agent or any Lender by reason of the
occurrence of any Loan Agreement Event of Default or the exercise of remedies
with respect thereto.

        (e) With respect to the occurrence and continuance of any Lease Default
under Section 16.1(a) or (b) of the Master Lease, the Lessor agrees that the
Agent or any Participant may give notice of such Lease Default on behalf of the
Lessor to the Lessee. With respect to any other Lease Default, the Lessor agrees
that the Agent or any Tranche B Lender may give notice of such Lease Default on
behalf of the Lessor to the Lessee. When a Lease Event of Default has occurred
and is continuing, Tranche A Lenders holding a majority of the outstanding
Tranche A Loans, or Tranche B Lenders holding a majority of the outstanding
Tranche B Loans, may exercise any or all of the remedies of the Lessor under
Article XVI of the Master Lease, and the Lessor shall exercise such remedies at
the direction of the Tranche A Lenders or the Tranche B Lenders, as the case may
be. The Lessor shall demand the purchase of Properties by the Lessee pursuant to
Section 18.3 of the Master Lease at the direction of either Tranche A Lenders
holding a majority of the outstanding Tranche A Loans or Tranche B Lenders
holding a majority of the outstanding Tranche B Loans.

        (f) Notwithstanding any other provision herein or in any other Operative
Document, the Tranche A Lenders shall not, without the written consent of the

                                      VIII

                                    THE AGENT

        VIII.1 Appointment. Each Lender hereby irrevocably designates and
appoints the Agent as the agent of such Lender under this Loan Agreement and the
other Operative Documents, and each such Lender irrevocably authorizes the
Agent, in such capacity, to take such action on its behalf under the provisions
of this Loan Agreement and the other Operative Documents and to exercise such
powers and perform such duties as are expressly delegated to the Agent by the
terms of this Loan Agreement and the other Operative Documents, together with
such other powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere in this Loan Agreement, the Agent shall not
have any duties or responsibilities, except those expressly set forth herein, or
any fiduciary relationship with any Lender or any other party to the Operative
Documents, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Loan Agreement or any other
Operative Document or otherwise exist against the Agent.

        VIII.2 Delegation of Duties. The Agent may execute any of its duties
under this Loan Agreement and the other Operative Documents by or through agents
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining 



                                      -10-
   14
to such duties. The Agent shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

        VIII.3 Exculpatory Provisions. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(a) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Loan Agreement or any other Operative
Document (except for its or such Person's own gross negligence or willful
misconduct) or (b) responsible in any manner to any of the Lenders or any other
party to the Operative Documents for any recitals, statements, representations
or warranties made by the Lessor or the Lessee or any officer thereof contained
in this Loan Agreement or any other Operative Document or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Agent under or in connection with, this Loan Agreement or any other
Operative Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Loan Agreement or any other Operative
Document or for any failure of the Lessor or the Lessee to perform its
obligations hereunder or thereunder. The Agent shall not be under any obligation
to any Lender or any other party to the Operative Documents to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Loan Agreement or any other Operative Document, or to
inspect the properties, books or records of the Lessor or the Lessee.

        VIII.4 Reliance by Agent. The Agent shall be entitled to rely, and shall
be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, facsimile message, statement, order or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Lessor or the Lessee), independent accountants and other experts selected by the
Agent. The Agent may deem and treat the payee of any Note as the owner thereof
for all purposes unless a written notice of assignment, negotiation or transfer
thereof shall have been filed with the Agent. The Agent shall be fully justified
in failing or refusing to take any action under this Loan Agreement or any other
Operative Document unless it shall first receive the advice or concurrence of
the Lenders holding a majority of the outstanding Loans or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Agent shall in all cases be fully protected in acting, or
in refraining from acting, under this Loan Agreement and the other Operative
Documents in accordance with a request of the Lenders holding a majority of the
outstanding Loans, and such request and any 



                                      -11-
   15
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Notes.

        VIII.5 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Loan Agreement Default or Loan
Agreement Event of Default hereunder unless the Agent has received notice from a
Lender or the Lessor referring to this Loan Agreement, describing such Loan
Agreement Default or Loan Agreement Event of Default and stating that such
notice is a "notice of default". In the event that the Agent receives such a
notice, the Agent shall promptly give notice thereof to the Lenders and the
Lessee. The Agent shall take such action with respect to such Loan Agreement
Default or Loan Agreement Event of Default as shall be directed by the Lenders
holding a majority of the outstanding Loans; provided, however, that unless and
until the Agent shall have received such directions, the Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Loan Agreement Default or Loan Agreement Event of Default as it
shall deem advisable in the best interests of the Lenders.

        VIII.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representations
or warranties to it and that no act by the Agent hereinafter taken, including
any review of the affairs of the Lessor or the Lessee, shall be deemed to
constitute any representation or warranty by the Agent to any Lender. Each
Lender represents to the Agent that it has, independently and without reliance
upon the Agent or any other Lender, and based on such documents and information
as it has deemed appropriate, made its own appraisal of and investigation into
the business, operations, property, financial and other condition and
creditworthiness of the Lessor and the Lessee and made its own decision to make
its Loans hereunder and enter into this Loan Agreement. Each Lender also
represents that it will, independently and without reliance upon the Agent or
any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Loan Agreement and the
other Operative Documents, and to make such investigation as it deems necessary
to inform itself as to the business, operations, property, financial and other
condition and creditworthiness of the Lessor and the Lessee. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Agent hereunder, the Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the business,
operations, property, condition (financial or otherwise), prospects or
creditworthiness of the Lessor or the Lessee which may come into the possession
of the Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates.



                                      -12-
   16

        VIII.7 Indemnification. The Lenders agree to indemnify the Agent in its
capacity as such (to the extent not reimbursed by the Lessee and without
limiting the obligation of the Lessee to do so), ratably according to the
percentage each Lender's Commitment bears to the total Commitments of all of the
Lenders on the date on which indemnification is sought under this Section 8.7
(or, if indemnification is sought after the date upon which the Lenders'
Commitments shall have terminated and the Loans shall have been paid in full,
ratably in accordance with the percentage that each Lender's Commitment bears to
the Commitments of all of the Lenders immediately prior to such date), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever (including without limitation all reasonable fees and disbursements
of any law firm or other external counsel of the Agent, the allocated cost of
internal legal services and all disbursements of internal counsel of the Agent)
which may at any time (including, without limitation, at any time following the
payment of the Notes) be imposed on, incurred by or asserted against the Agent
in any way relating to or arising out of, the Commitments, this Loan Agreement,
any of the other Operative Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by the Agent under or in connection with any of
the foregoing; provided, however, that no Lender shall be liable for the payment
of any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting solely
from the Agent's gross negligence or willful misconduct. The agreements in this
Section 8.7 shall survive the payment of the Notes and all other amounts payable
hereunder.

        VIII.8 Agent in Its Individual Capacity. The Agent and its Affiliates
may make loans to, issue letters of credit for the account of, accept deposits
from, acquire equity interests in and generally engage in any kind of banking,
trust, financial advisory, underwriting or other business with the Lessor, the
Lessee and their Affiliates as though The Industrial Bank of Japan, Limited, San
Francisco Agency were not the Agent hereunder and under the other Operative
Documents and without notice to or consent of the Lenders. Each Lender
acknowledges that, pursuant to such activities, The Industrial Bank of Japan,
Limited, San Francisco Agency or its Affiliates may receive information
regarding the Lessee, the Lessor or their Affiliates (including information that
may be subject to confidentiality obligations in favor of the Lessee, the Lessor
or their Affiliates) and acknowledge that the Agent shall be under no obligation
to provide such information to them. With respect to any Loans made or renewed
by it and any Note issued to it, The Industrial Bank of Japan, Limited, San
Francisco Agency shall have the same rights and powers under this Loan Agreement
and the other Operative Documents as any Lender and may exercise the same as
though it were not the Agent, and, in the event The 



                                      -13-
   17
Industrial Bank of Japan, Limited, San Francisco Agency becomes a Lender, the
terms "Lender" and "Lenders" shall include The Industrial Bank of Japan,
Limited, San Francisco Agency in its individual capacity.

        VIII.9 Successor Agent. The Agent may resign as Agent upon twenty (20)
days' notice to the Lenders. If the Agent shall resign as Agent under this Loan
Agreement and the other Operative Documents, then Lenders holding a majority of
the outstanding Loans shall appoint a successor agent for the Lenders, which
successor agent shall be a commercial bank organized under the laws of the
United States of America or any State thereof or under the laws of another
country which is doing business in the United States of America and having a
combined capital, surplus and undivided profits of at least $100,000,000 (and if
no Lease Default or Lease Event of Default exists, shall be approved by the
Lessee (which consent shall not be unreasonably withheld)), whereupon such
successor agent shall succeed to the rights, powers and duties of the Agent, and
the term "Agent" shall mean such successor agent effective upon such appointment
and approval, and the former Agent's rights, powers and duties as Agent shall be
terminated, without any other or further act or deed on the part of such former
Agent or any of the parties to this Loan Agreement or any holders of the Notes.
If no successor Agent has accepted appointment as Agent by the date which is
twenty (20) days following a resigning Agent's notice of resignation, the
resigning Agent's resignation shall nevertheless thereupon become effective and
the Lenders shall perform all of the duties of the Agent hereunder until such
time, if any, as Lenders holding a majority of the outstanding Loans appoint a
successor Agent as provided above. After any retiring Agent's resignation as
Agent, all of the provisions of this Article VIII shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Agent under this
Loan Agreement and the other Operative Documents.

                                       IX

waiver 



                                      -14-
   18
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

        IX.4 Survival of Representations and Warranties. All representations and

        IX.6 Adjustments. If any Lender (a "Benefitted Lender") shall at any
time receive any payment of all or part of its Loans, or interest thereon, or
receive any collateral in respect thereof (whether voluntarily or involuntarily,
by setoff, pursuant to events or proceedings of the nature referred to in
Section 6.1(e), or otherwise), in a greater proportion than any such payment to
or collateral received by any other Lender, if any, in respect of such other
Lender's Loans, or interest thereon, such Benefitted Lender shall purchase for
cash from the other Lenders a participating interest in such portion of each
such other Lender's Loan, or shall provide such other Lenders with the benefits
of any such collateral, or the proceeds thereof, as shall be necessary to cause
such Benefitted Lender to share the excess payment or benefits of such
collateral or proceeds ratably with each of the Lenders; provided, however, that
if all or any portion of such excess payment or benefits is thereafter recovered
from such Benefitted Lender, such purchase shall be rescinded, and the purchase
price and benefits returned, to the extent of such recovery, but without
interest.

        IX.7 Counterparts. This Loan Agreement may be executed by one or more of
the parties to this Loan Agreement on any number of separate counterparts
(including by telecopy), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Loan Agreement signed by all the parties shall be lodged with the Lessor and the
Agent.

        IX.8 Severability. Any provision of this Loan Agreement 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.

                                       V

                        Certain Intentions of the Parties

                  V.1 Nature of Transaction. (a) The parties hereto intend that
(i) for financial accounting purposes with respect to the Lessee, the Lessor
will be treated as the owner and the lessor of the Properties and the Lessee
will be treated as the lessee of the Properties and (ii) for all other purposes,
including

                                      -9-
   42
federal and all state and local income tax purposes, state real estate and
commercial law and bankruptcy purposes, (A) the Master Lease will be treated as
a financing arrangement, (B) the Lessor and the Lenders will be deemed lenders
making loans to the Lessee in an amount equal to the sum of the Equity Amounts
and the outstanding principal amount of the Loans, which loans are secured by
the Properties and (C) the Lessee will be treated as the owner of the Properties
and will be entitled to all tax benefits ordinarily available to an owner of
properties like the Properties for such tax purposes. Nevertheless, the Lessee
acknowledges and agrees that neither the Lessor nor any of the Lenders has made
any representations or warranties to the Lessee concerning the tax, accounting
or legal characteristics of the Operative Documents and that the Lessee has
obtained and relied upon such tax, accounting and legal advice concerning the
Operative Documents as it deems appropriate. The parties hereto agree that they
shall modify the Operative Documents to the extent reasonably necessary to
enable the Master Lease to qualify as an operating lease for financial
accounting purposes under FASB 13 as applied and interpreted by the Lessee's
independent outside auditors, including but not limited to, and to the extent
necessary, (i) changes in the relationship (but not the aggregate total) of the
Tranche A Loan Commitment, the Tranche B Loan Commitment, and the Lessor
Commitment (except that the Lessor Commitment shall not be increased by more
than $500,000), and (ii) adjustments to amortization payments to be made on
account of the Tranche A Loan Balance with respect to Property No. 1. In no
event shall such modifications individually or in the aggregate result in a
material change for any Participant.

         (a) Specifically, without limiting the generality of clause (a) of this
Section 1, the parties hereto intend and agree that in the event of any
insolvency or receivership proceedings or a petition under the United States
bankruptcy laws or any other applicable insolvency laws or statute of the United
States of America or any State or Commonwealth thereof affecting the Lessee, the
Lessor or the Lenders or any collection actions, the transactions evidenced by
the Operative Documents shall be regarded as loans made by the Lessor and the
Lenders as unrelated third party lenders of the Lessee.

                  V.2 Amounts due under Master Lease. Anything else herein or
elsewhere to the contrary notwithstanding, it is the intention of the Lessee,
the Lessor and the Lenders that: (i) the amount and timing of installments of
Basic Rent due and payable from time to time from the Lessee under the Master
Lease shall be equal to the aggregate payments due and payable as interest on
the Loans and Equity Yield on the Equity Amounts on each Payment Date; (ii) if
the Lessee elects the Early Purchase Option or becomes obligated or otherwise
elects to purchase any of the Properties under the Master Lease, the Loans, the
Equity Amounts, all interest and Equity Yield thereon and all other obligations
of the Lessee owing to the Lessor and the Lenders

                                      -10-
   43
shall be paid in full by the Lessee; (iii) if the Lessee properly elects the
Remarketing Option with respect to any Property, the Lessee shall only be
required to pay to the Lessor the proceeds of the sale of such Property, the
Recourse Amount with respect to such Property and any amounts due pursuant to
Article XIII hereof and Section 20.2 of the Master Lease (which aggregate
amounts may be less than the Lease Balance); and (iv) upon an Event of Default
resulting in an acceleration of the Lessee's obligation to purchase the
Properties under the Master Lease, the amounts then due and payable by the
Lessee under the Master Lease shall include all amounts necessary to pay in full
the Lease Balance, plus all other amounts then due from the Lessee to the
Participants under the Operative Documents.

                             Conditions Precedent to

         making of such Advance and the application of the proceeds thereof),

         contained herein and in each of the other Operative Documents shall be
         true and correct in all material respects as though made on and as of
         such date, except to the extent such representations or warranties
         relate solely to an earlier date, in which case such representations
         and warranties shall have been true and correct in all material
         respects on and as of such earlier date.

                           (g) Litigation. On the applicable Acquisition Date or

         ERISA) which is subject to Title I of ERISA, or "plan" (as defined in
         Section 4975(e)(1) of the Code).

                           (b) Status. Such Participant is a commercial bank,

         requisite power and authority to enter into and perform under the
         Operative Documents to which it is a party.

The making of any Loan or the advancing of any Equity Amount on any Acquisition

subject Participant of the preceding representations and warranties.

                  VIII.2 Representations of Lessee. The Lessee represents and
warrants to each of the other parties hereto that:

                           (a) Organization, etc. The Lessee is a corporation
         validly organized and existing and in good standing under the laws of
         the State of Delaware and is duly qualified to do business and is in
         good standing as a foreign corporation in each jurisdiction where any
         Property is located. The Lessee has full power and authority and holds
         all requisite governmental licenses, permits and other approvals to
         enter into and perform its Obligations under this Participation
         Agreement and each other Operative Document to which it is a party and
         to own and hold under lease the Properties and to conduct its business
         substantially as currently conducted by it.

                                      -17-
   50
                  (b) Due Authorization, Non-Contravention, etc. The execution,
         delivery and performance by the Lessee of this Participation Agreement,
         and each other Operative Document executed or to be executed by it are
         within the Lessee's corporate powers, have been duly authorized by all
         necessary corporate action, and do not

                  (i) contravene the Lessee's Organic Documents;

                  (ii) contravene any material contractual restriction the
         contravention of which is reasonably likely to have a material adverse
         effect on the financial condition of the Lessee (including any covenant
         relating to the incurrence of indebtedness, which restrictions the
         Lessee hereby acknowledges are material), law or governmental
         regulation or court decree or order binding on or affecting the Lessee;
         or

                  (iii) result in, or require the creation or imposition of, any
         Lien on any of the Lessee's properties (including the Properties) other
         than as are contemplated by the Operative Documents.

                  (c) Government Approval, Regulation, etc. No authorization or
         approval or other action by, and no notice to or filing with, any
         governmental authority or regulatory body or other Person is required
         for the due execution, delivery or performance by the Lessee of this
         Participation Agreement, or any other Operative Document to which it is
         a party. The Lessee is not an "investment company" within the meaning
         of the Investment Company Act of 1940, as amended.

                  (d) Validity, etc. This Participation Agreement constitutes
         and each other Operative Document executed by the Lessee will, on the
         due execution and delivery thereof, constitute, the legal, valid and
         binding obligations of the Lessee enforceable in accordance with their
         respective terms, and each Operative Document executed pursuant hereto
         will, on the due execution and delivery thereof, be the legal, valid
         and binding obligation of Lessee enforceable in accordance with its
         terms, subject, in each case, as to enforceability, to bankruptcy,
         insolvency, reorganization and other similar laws affecting enforcement
         of creditor rights generally (insofar as any such law relates to the
         bankruptcy, insolvency, reorganization or similar event of the Lessee)
         and, as to the availability of specific performance or other injunctive
         relief, subject to the discretionary power of a court to deny such
         relief and to general equitable principles.

   51
                           (e) No Material Adverse Change. Since the date of the
         financial statements described in Section k, there has been no Material
         adverse change in the consolidated assets, liabilities, results of
         operations, financial condition or prospects of the Lessee except for
         those matters relating to or reflected by the restructuring charge in
         the approximate amount of $85 million taken or to be taken by the
         Lessee with respect to its financial statements to be issued relating
         to the fiscal quarter ended March 29, 1998.

                           (f) Litigation. Except as disclosed in the financial
         statements described in Section k, there is no pending or, to the
         knowledge of the Lessee, threatened, litigation, action or governmental
         proceeding affecting the Lessee or any of its properties (including the
         Properties), businesses, assets or revenues, which (i) is reasonably
         likely to Materially and adversely affect the overall financial
         condition, operations, assets, business or properties (including the
         Properties) of the Lessee and which creates a material risk of causing
         the Lessee to be unable to perform its obligations under the Operative
         Documents or (ii) which purports to affect the legality, validity or
         enforceability of this Participation Agreement, the Notes or any other
         Operative Document.

                           (g) Provided Information. The information and
         materials described on Schedule II which were provided by the Lessee to
         one or more of the Participants prior to the applicable Acquisition
         Date or Funding Date, as the case may be, do not contain any Material
         inaccuracies on the date as of which such information and materials
         are dated or certified and are not incomplete by omitting to state any
         fact necessary to make such information (taken as a whole) not
         misleading at such time in light of the circumstances under which such
         information was provided, except to the extent any such inaccuracy or
         omission does not relate to the Properties and is not reasonably likely
         to have a Material adverse effect on the overall financial condition of
         the Lessee.

                           (h) Pension and Welfare Plans. During the twelve
         consecutive-month period prior to the Documentation Date, no steps have
         been taken to terminate any underfunded Pension Plan, and no
         contribution failure has occurred with respect to any Pension Plan
         sufficient to give rise to a Lien under section 302(f) of ERISA with
         respect to a liability or obligation in excess of $10,000,000. No
         condition

                                      -19-
   52
         exists or event or transaction has occurred with respect to any Pension
         Plan which might result in the incurrence by the Lessee or any member
         or the Controlled Group of any Material liability, fine or penalty.
         Neither the Lessee nor any member of the Controlled Group has any
         Material contingent liability with respect to any post-retirement
         benefit under a Welfare Plan, other than liability for continuation
         coverage described in Part 6 of Title I of ERISA.

                  (i) Environmental Laws. Except as disclosed in Item A
         ("Compliance with Environmental Laws") of Schedule III:

         groundwater) owned or leased by the Lessee or any of its Subsidiaries
         have been, and continue to be, owned or leased by the Lessee and its
         Subsidiaries in compliance in all material respects with all
         Environmental Laws; and

                  (ii) there have been no past, and there are no pending or
         threatened

                           (a) claims, complaints, notices or requests for
                  information received by Lessee or any of its Subsidiaries with
                  respect to any alleged violation of any Environmental Law,
                  which may reasonably be expected to have a Material adverse
                  effect on the financial condition, operations, assets,
                  business or properties of Lessee and its Subsidiaries or which
                  may reasonably be expected to have a Material adverse effect
                  on any Property, or

                           (b) complaints, notices or inquiries to Lessee or any
                  of its Subsidiaries regarding potential liability under any
                  Environmental Law, which may reasonably be expected to have a
                  Material adverse effect on the financial condition,
                  operations, assets, business or properties of Lessee and its
                  Subsidiaries.

                  (j) Offer of Securities, etc. None of the Lessee, nor any
         Person authorized to act on the Lessee's behalf has, directly or
         indirectly, offered the Notes or any other similar securities (the sale
         or offer of which would be integrated with the sale or offer of the
         Notes), for sale to, or solicited any offer to acquire any of the same
         from, any Person other than the Participants and other "accredited
         investors" (as defined in Regulation D of the Securities and Exchange
         Commission).

         sheet of the Lessee and its Subsidiaries at December 31, 1997, and the
         related consolidated statements of income and cash flows of Lessee and
         its Subsidiaries, copies of which have been furnished to the parties

         Properties by the Lessee and its agents, assignees, employees, lessees,

         Laws). There is no action, suit or proceeding (including any proceeding
         in condemnation or eminent domain or under any Environmental Law)
         pending or, to the best knowledge of the Lessee, threatened with

         Property which adversely affects the title to, or materially and
         adversely affects the use, operation or value of, such Property. No
         fire or other casualty has occurred which has had a Material adverse
         effect on any Property. To the best of the Lessee's knowledge all
         utilities serving such Property, or proposed to serve such Property in
         accordance with the related Plans and Specifications, are or will be
         located in, and vehicular access to the Improvements on the applicable

   54
         Property during the construction of the applicable Improvements
         thereon, and (y) construction of such Improvements in accordance with
         the related Plans and Specifications and the Construction Agency
         Agreement have either been obtained from the appropriate Governmental
         Authorities having jurisdiction or from private parties, as the case
         may be, or will be obtained from the appropriate Governmental
         Authorities having jurisdiction or from private parties, as the case
         may be, prior to the time required by such Governmental Authority or
         private party.

                           (n) Title. Each Deed is in form and substance
         sufficient to convey title to the applicable Property in fee simple,
         contains all customary seller's warranties (or such other seller's
         warranties as are reasonably acceptable to the Lessor and the
         Participants) and is subject only to Permitted Exceptions.

                           (o) Insurance. The Lessee has obtained insurance
         coverage covering each Property which meets the requirements of Article
         XIII of the Master Lease, and such coverage is in full force and
         effect. The Lessee carries insurance with reputable insurers in respect
         of the Properties and its Material Assets, in such manner, in such
         amounts and against such risks as is customarily maintained by the
         Lessee.

                           (p) Flood Hazard Areas. Except as otherwise
         identified on the survey delivered pursuant to Section v, to the best
         knowledge of the Lessee no portion of any Property is located in an
         area identified as a special flood hazard area by the Federal Emergency
         Management Agency or other applicable agency. If the Property is
         located in an area identified as a special flood hazard area by the
         Federal Emergency Management Agency or other applicable agency, then
         flood insurance has been obtained for such Property in accordance with
         Section 13.2 of the Master Lease and in accordance with the National
         Flood Insurance Act of 1968, as amended.

                           (q) Lease Supplements. With respect to each Property,
         upon the execution and delivery of the applicable Lease Supplement, (i)
         the Lessee will have unconditionally accepted such Property (provided
         that nothing contained herein shall be deemed a waiver by the Lessee of
         any right of action against Persons with respect to title to and
         condition of the Property on the applicable Acquisition Date other than
         the Lessor and the Lenders) and will have good and marketable title to
         a valid and subsisting leasehold interest in such Property, subject
         only to Permitted Liens and

                                      -22-
   55
         (ii) no right of offset will exist with respect to any Rent or other
         sums payable under the Master Lease.

                           (r) Defaults. The Lessee is not in default under (and
         no event has occurred which with the lapse of time or notice or action
         by a third party could result in a default under) any mortgage, loan
         agreement, indenture or other instrument under which there may be
         issued or by which there may be secured or evidenced, any indebtedness
         of the Lessee, whether such indebtedness now exists or shall hereafter
         be created, which indebtedness individually or in the aggregate exceeds
         $20,000,000.

                           (s) Use of Loans and Proceeds. No part of any Advance
         will be used directly or indirectly for the purpose of purchasing or
         carrying, or for payment in full or in part of indebtedness that was
         incurred for the purposes of purchasing or carrying, any margin
         security as such term is defined in Section 207.2 of Regulation G of
         the F.R.S. Board (12 C.F.R., Chapter II, Part 207).

                           (t) Regulations G, U and X. The Lessee is not engaged
         in the business of extending credit for the purpose of purchasing or
         carrying margin stock, and no proceeds of any of the Advances will be
         used for a purpose which violates, or would be inconsistent with,
         F.R.S. Board Regulation G, U or X. Terms for which meanings are
         provided in F.R.S. Board Regulation G, U or X or any regulations
         substituted therefor, as from time to time in effect, are used in this
         Section with such meanings.

                  VIII.3 Representations of Lessee With Respect to Each Advance.
The Lessee represents and warrants to each of the other parties as of each
Funding Date (including each Acquisition Date) on which an Advance is made as
follows:

                           (a) Representations and Warranties. The
         representations and warranties of the Lessee set forth in the Operative
         Documents (including the representations and warranties set forth in
         Section 2) are true and correct on and as of such Funding Date except
         to the extent such representations or warranties relate solely to an
         earlier date, in which case such representations and warranties shall
         have been true and correct on and as of such earlier date. No Event of
         Default has occurred and is continuing and no Default of which the
         Lessee has knowledge and that has not been previously disclosed to the
         Agent, the Lessor and the Participants has occurred and is continuing
         under the Master Lease, the Guaranty or the Construction Agency
         Agreement or, to the knowledge of

                                      -23-
   56
         the Lessee, any other Operative Document. No Default or Event of
         Default under the Master Lease, the Guaranty or the Construction Agency
         Agreement or, to the knowledge of the Lessee, any other Operative
         Document will occur as a result of, or after giving effect to, the
         Advance requested by the Funding Request on such date.

                           (b) Improvements. The Construction of the

         prior to the determination date; plus (iii) one hundred percent (100%)
         of the Net Proceeds (as such term is defined in the Credit Agreement)

         commencing on the base date and ending on the determination date; and
         (iv) one hundred percent (100%) of the aggregate decrease in the total

         Subsidiaries during the period commencing on the base date and ending
         on the determination date. The parties hereto

                                      -30-

         Lien (including any Lessor Lien) upon the Master Lease or any of the
         Properties (other than as contemplated by any of the Operative
         Documents);

                  (b) it will use its best efforts to remove any Lien (including
         any Lessor Lien) created, incurred, assumed or suffered to exist by it
         upon the Master Lease or any of the Properties (other than the Lender
         Deeds of Trust and such other Liens as are contemplated by any of the
         Operative Documents); provided, however, that any action taken pursuant
         to this clause (b) shall not limit the Lessee's rights or remedies
         under any of the Operative Documents; and

                  (c) it will grant any license or easement to the Lessee
         reasonably necessary for the use and enjoyment of the Property.

                  X.4 Covenant of the Lenders. Each Lender hereby agrees that,
upon repayment in full in cash of all Loans relating to any Property, such
Lender shall execute and deliver to the Lessee a release of any Lender Deed of
Trust in favor of such Lender relating to such Property, releases of the
Construction Agency Agreement Assignment and Assignment of Leases and Rents (in
each case to the extent relating to such Property), and termination statements

naming such Lender as secured party. Each Lender agrees to grant any license or
easement to the Lessee reasonably necessary for the use and enjoyment of the
Property.

         any other right of the Lessor under the Loan Agreement upon not less
         than two (2) Business Days' prior written notice from the Lessee to the

requests, in accordance with Section 19.1 of the Master Lease, that the Base

Participant") with a replacement bank or other financial institution (a
"Replacement Participant") satisfactory to the Lessee, with such replacement to

all Equity Amounts, in the case of the Lessor, (B) all accrued interest, in the
case of a Lender, and all accrued Equity Yield, in the case of the Lessor, and
(C) all other amounts owing to such NonConsenting Participant on or prior to the
date of replacement, in each case, (iii) the Lessee shall be liable to such
NonConsenting Participant under Article XIII if any Loan or Equity Amount, as
the case may be, owing to such Non-Consenting Participant shall be prepaid (or
purchased) other than on the last day of the Interest Period or Interest Periods
relating thereto, (iv) such replacement shall be made in accordance with the
provisions of Article XII (provided that the Lessee or the relevant Replacement
Participant shall be obligated to pay the Transaction Expenses arising in
connection therewith) and (v) the Replacement Participant shall have agreed to
be subject to all of the terms and conditions of the applicable Operative
Documents (including the extension of the Maturity Date contemplated by the
relevant request for extension). The Participants hereby agree to cooperate with
the Lessee or the Lessor, as the case may be, in its efforts to arrange one or
more Replacement Participants as contemplated by this Section b.

                      Transfers of Participants' Interests

                  XII.1 Assignments. All or any part of the interest of any
Participant in, to or under this Participation Agreement, the other Operative
Documents, the Properties or the Notes may be assigned or transferred by such
Participant at any time to any Affiliate of such Participant or, with the
consent of the Lessee (such consent not to be unreasonably withheld), to any
other Person; provided, however, that (a) each assignment or transfer shall
comply with all applicable securities laws; (b) each such assigning Participant,
which is a Lender as of the Documentation Date, shall retain at least $5,000,000
from the time of such assignment (notwithstanding amortization) of its Loan
Balance; (c) the Agent shall receive a fee of $2,500 payable by the assignee;
and (d) any assignee or transferee (i) acknowledges that the obligations to be
performed from and after the date of such transfer or assignment under this
Participation Agreement and all other Operative Documents are its obligations,
including the obligations imposed by this Section 1 (and the transferor and
transferee Participant shall deliver to the Lessee, the Lessor and the Agent an
Assignment Agreement, in substantially the form of Exhibit D, executed by the
assignee or transferee) and (ii) further represents and warrants to the Agent,
the Lessor, each Participant and the Lessee that:

                  (A) it is a commercial bank, savings and loan association,
         savings bank, pension plan, depository institution, insurance company,
         branch or agency of a foreign bank or other similar financial
         institution, in each case, having a minimum capital and surplus of: (A)
         $500,000,000, in the case of an assignment of an interest of a Tranche
         A Lender; or (B) $50,000,000, in the case of an assignment of an
         interest of a Tranche B Lender or the Lessor;

                  (B) it has the requisite power and authority to accept such
         assignment or transfer;

                  (C) it will not transfer any Note unless the proposed
         transferee makes the foregoing representations and covenants;

                  (D) it will not take any action with respect to such Note that
         would violate any applicable securities laws;

                  (E) it will not assign or transfer any interest in its Note
         except in compliance with this Section 1; and

                                      -33-
   66
                  (F) in the case of the Lessor, any assignment or transfer of
         its interest hereunder shall not affect the obligations contained in
         the Lessor Guarantee.

                  XII.2 Participations. Any Participant may at any time sell
to one or more commercial banks or other Persons (each of such commercial banks
and other Persons being herein called a "Sub-Participant") participating
interests in all or a portion of its rights and obligations under this
Participation Agreement, the other Operative Documents, the Properties or its
Notes (including, without limitation, all or portion of the Rent owing to it);
provided, however, that

                  (a) no participation contemplated in this Section 2 shall
         relieve such Participant from its obligations hereunder or under any
         other Operative Document;

                  (b) such Participant shall remain solely responsible for the
         performance of its Commitment and such other obligations;

                  (c) the Lessee shall continue to deal solely and directly with
         such Participant in connection with such Participant's rights and
         obligations under this Participation Agreement and each of the other
         Operative documents;

                  (d) no Sub-Participant, unless such Sub-Participant is an
         Affiliate of such Participant, or is itself a Participant, shall be
         entitled to require such Participant to take or refrain from taking any
         action hereunder or under any other Operative Document.

Each Participant agrees that it will notify the Lessee promptly of the identity
of each Sub-Participant to which it sells a participating interest hereunder and
the amount of such participating interest. The Lessee acknowledges and agrees
that each Sub-Participant, for purposes of Article XIII, shall be considered a
Participant.

                  XII.3 Withholding Taxes; Disclosure of Information; Pledge
Under Regulation A. (a) If any Participant (or the assignee of or
Sub-Participant in any Note of a Participant, each a "Transferee") is organized
under the laws of any jurisdiction other than the United States or any State
thereof, then such Participant or the Transferee of such Participant, as
applicable, shall (as a condition precedent to acquiring or participating in
such Loan and as a continuing obligation to the Lessor and the Lessee) (i)
furnish to the Lessor and the Lessee in duplicate, for each taxable year of such
Participant or Transferee during the Term of the Master Lease with respect to
the Properties, a properly completed and executed copy of either

                                      -34-
   67
Internal Revenue Service Form 4224 or Internal Revenue Service Form 1001 and
Internal Revenue Service Form W-8 or Internal Revenue Service Form W-9 and any
additional form (or such other form) as is necessary to claim complete exemption
from United States withholding taxes (wherein such Transferee claims entitlement
to complete exemption from United States withholding taxes on all payments
hereunder), and (ii) provide to the Lessor and the Lessee a new Internal Revenue
Service Form 4224 or Internal Revenue Service Form 1001 and Internal Revenue
Service Form W-8 or Internal Revenue Service Form W-9 and any such additional
form (or any successor form or forms) upon the expiration or obsolescence of any
previously delivered form and comparable statements in accordance with
applicable United States laws and regulations and amendments duly executed and
completed by such Participant or Transferee, and to comply from time to time
with all applicable United States laws and regulations with regard to such
withholding tax exemption. By its acceptance of a participation or assignment of
a Lender's Note, each Transferee shall be deemed bound by the provisions set
forth in this Article XII.

         (a) Subject to the terms of any confidentiality agreements executed by
any of the parties hereto, any Participant may, in connection with any
assignment or participation or proposed assignment or participation pursuant to
this Article XII, disclose to the assignee or participant or proposed assignee
or participant, any information relating to the Lessee.

         (b) Anything in this Article XII to the contrary notwithstanding, any
Participant may without the consent of the Lessee assign and pledge all or any
portion of the Notes held by it to any Federal Reserve Bank, the United States
Treasury or to any other financial institution as collateral security pursuant
to Regulation A of the F.R.S. Board and any operating circular issued by the
Federal Reserve System and/or the Federal Reserve Bank or otherwise.

                                Indemnification

                  XIII.1 General Indemnification. The Lessee agrees, whether or
not any of the transactions contemplated hereby shall be consummated, to assume
liability for, and to indemnify, protect, defend, save and keep harmless each
Indemnitee, on an After Tax Basis, from and against, any and all Claims that may
be imposed on, incurred by or asserted against such Indemnitee (whether because
of action or omission by such Indemnitee or otherwise), whether or not such
Indemnitee shall also be indemnified as to any such Claim by any other Person
and whether or not such Claim arises or accrues prior to the applicable
Acquisition Date or after the Expiration Date, in any way relating to or arising
out of:

                                      -35-
   68
                  (a) any of the Operative Documents or any of the transactions
         contemplated thereby, and any amendment, modification or waiver in
         respect thereof;

                  (b) the Properties or any part thereof or interest therein;

         sublease, repossession, maintenance, repair, alteration, modification,
         addition or substitution, storage, transfer of title, redelivery, use,

         XVIII or XX of the Master Lease), return or other disposition of all or
         any part or any interest in the Properties or the imposition of any
         Lien (or incurring of any liability to refund or pay over any amount as
         a result of any Lien) thereon, including, without limitation: (1)
         Claims or penalties arising from any violation of law or in tort
         (strict liability or otherwise), (2) latent or other defects, whether
         or not discoverable, (3) any Claim based upon a violation or alleged
         violation of the terms of any restriction, easement, condition or
         covenant or other matter affecting title to the Properties, (4) the
         making of any Modifications in violation of any standards imposed by
         any insurance policies required to be maintained by Lessee pursuant to
         the Master Lease which are in effect at any time with respect to the
         Properties or any part thereof, (5) any Claim for patent, trademark or
         copyright infringement, and (6) Claims arising from any public
         improvements with respect to the Properties resulting in any change or
         special assessments being levied against the Property or any plans to
         widen, modify or realign any street or highway adjacent to any of the
         Properties, or any Claim for utility "tap-in" fees;

                  (d) the breach by the Lessee of any covenant, representation
         or warranty made by it or deemed made by it in any Operative Document
         or any certificate required to be delivered by any Operative Document;

                  (e) the retaining or employment of any broker, finder or
         financial advisor by the Lessee to act on its behalf in connection with
         this Participation Agreement;

                                      -36-
   69
                  (f) the existence of any Lien on or with respect to the
         Properties, the Improvements, any Basic Rent or Supplemental Rent,
         title thereto, or any interest therein including any Liens which arise
         out of the possession, use, occupancy, construction, repair or
         rebuilding of the Property or by reason of labor or materials furnished
         or claimed to have been furnished to the Lessee, or any of its
         contractors or agents or by reason of the financing of any personalty
         or equipment purchased or leased by the Lessee or Modifications
         constructed by the Lessee, except Lessor Liens and Liens in favor of
         the Lender or the Lessor; or

                  (g) subject to the accuracy of any Participant's
         representation set forth in Section a, as to such Participant, the
         transactions contemplated by the Master Lease or by any other Operative
         Document, in respect of the application of Parts 4 and 5 of Subtitle B
         of Title I of ERISA and any prohibited transaction described in Section
         4975(c) of the Code;

provided, however, the Lessee shall not be required to indemnify any Indemnitee
under this Section 1 for any of the following: (1) any Claim to the extent
resulting from the willful misconduct or gross negligence of such Indemnitee (it
being understood that the Lessee shall be required to indemnify an Indemnitee
even if the ordinary (but not gross) negligence of such Indemnitee caused or
contributed to such Claim) or the breach of any representation, warranty or
covenant of such Indemnitee set forth in any Operative Document, (2) any Claim
resulting from Lessor Liens, Lender Deeds of Trust or other Liens contemplated
by any of the Operative Documents to the extent such Indemnitee is in breach of
any obligation under the Operative Documents to discharge such Liens, (3) any
Claim to the extent attributable to acts or events occurring after the
termination of the Master Lease, the expiration of the Term, the return of the
Property by the Lessee to the Lessor, or the remarketing of the Property so long
as the Lessor and the Lenders are not exercising remedies against the Lessee in
respect of the Operative Documents, (4) any Claim arising from a breach or
alleged breach by the Lenders or the Lessor of any agreement entered into in
connection with the assignment or participation of any Loan or Equity Amount,
and (5) subject to Section 5, any Claim arising from taxes based on, or measured
by the net income of a Tax Indemnitee imposed by the United States (or any state
or other jurisdiction, political subdivision or taxing authority thereof or
therein). It is expressly understood and agreed that the indemnity provided for
herein shall survive the expiration or termination of and shall be separate and
independent from any remedy under the Master Lease or any other Operative
Document. Without limiting the express rights of any Indemnitee under this
Section 1, this Section 1

                                      -37-
   70
shall be construed as an indemnity only and not a guaranty of residual value of
the Properties or as a guaranty of the Notes.

                  XIII.2 End of Term Indemnity. (a) If the Lessee elects the
Remarketing Option and there would, after giving effect to the proposed
remarketing transactions, be a Shortfall Amount, then prior to the Maturity Date
and as a condition to the Lessee's right to complete the remarketing of the
Properties pursuant to Section 20.1 of the Master Lease, the Lessee shall cause
to be delivered to the Lessor at least 120 days prior to the Expiration Date, at
the Lessee's sole cost and expense, a report from the Appraiser in form and
substance satisfactory to the Participants (the "End of the Term Report") which
shall state the appraiser's conclusions as to the reason for any decline in the
Fair Market Sales Value of any Property from that anticipated for such date in
the Property Appraisal delivered on or prior to the applicable Completion Date.

         (a) If the Lessee elects the Remarketing Option, then on or prior to
the Expiration Date the Lessee shall pay to the Lessor an amount (not to exceed
the Shortfall Amount) equal to the portion of the Shortfall Amount that the End
of the Term Report demonstrates was the result of a decline in the Fair Market
Sales Value of the applicable Property due to

                  (i) extraordinary use, failure to maintain, to repair, to
         restore, to rebuild or to replace, failure to comply with all
         applicable laws, failure to use, workmanship, method of installation or
         removal or maintenance, repair, rebuilding or replacement, (excepting
         in each case ordinary wear and tear), or

                  (ii) any change to the Plans and Specifications after the date
         of the applicable Property Appraisal, or any Modification made to, or
         any rebuilding of, the applicable Properties or any part thereof by the
         Lessee, or

                  (iii) the existence of any Hazardous Activity, Hazardous
         Substance or Environmental Violations, the indemnity for which shall
         not exceed the cost of the remediation thereof, or

                  (iv) any restoration or rebuilding carried out by the Lessee,
         or

                  (v) any condemnation of any portion of any of the applicable
         Properties pursuant to Article XIV of the Master Lease, or

                  (vi) any use of any of the applicable Property or any part
         thereof by the Lessee other than as a first-class research and
         production facility, or

                                      -38-
   71
                  (vii) any grant, release, dedication, transfer, annexation or
         amendment made pursuant to Section 11.2 of the Master Lease, or

                  (viii) the failure of the Lessor to have good and marketable
         title to the applicable Property free and clear of all Liens (excluding
         Permitted Liens), or

                  (ix) the existence of any sublease relating to any of the
         applicable Properties that shall survive the Expiration Date, or

                  (x) the existence of any Liens on the Applicable Property
         other than Permitted Liens of the types described in clauses (i),
         (viii) and (x) of the definition of "Permitted Liens".

                  XIII.3 Environmental Indemnity. Without limitation of the
other provisions of this Article XIII, the Lessee hereby agrees to indemnify,
hold harmless and defend each Indemnitee from and against any and all claims
(including without limitation third party claims for personal injury or real or
personal property damage), losses (including but not limited to, to the extent
the Lease Balance has not been fully paid, any loss of value of the Property
related thereto), damages, liabilities, fines, penalties, charges,
administrative and judicial proceedings (including informal proceedings) and
orders, judgments, remedial action, requirements, enforcement actions of any
kind, and all reasonable and documented costs and expenses incurred in
connection therewith (including but not limited to reasonable and documented
attorneys' and/or paralegals' fees and expenses), including, but not limited to,
all costs incurred in connection with any investigation or monitoring of site
conditions or any clean-up, remedial, removal or restoration work by any
federal, state or local government agency, arising in whole or in part, out of

                  (a) the presence on or under any of the Properties of any
         Hazardous Substances, or any releases or discharges of any Hazardous
         Substances on, under, from or onto any of the Properties,

                  (b) any activity, including, without limitation, construction,
         carried on or undertaken on or off any of the Properties, and whether
         by the Lessee or any predecessor in title or any employees, agents,
         contractors or subcontractors of the Lessee or any predecessor in
         title, or any other Persons (including such Indemnitee), in connection
         with the handling, treatment, removal, storage, decontamination,
         clean-up, transport or disposal of any Hazardous Substances that at any
         time are located or present on or under or that at any time migrate,
         flow, percolate, diffuse or in any way move onto or under any of the
         Properties,

                                      -39-
   72
                  (c) loss of or damage to any property or the environment
         (including, without limitation, clean-up costs, response costs,
         remediation and removal costs, cost of corrective action, costs of
         financial assurance, fines and penalties and natural resource damages),
         or death or injury to any Person, and all expenses associated with the
         protection of wildlife, aquatic species, vegetation, flora and fauna,
         and any mitigative action required by or under Environmental Laws,

                  (d) any claim concerning lack of compliance with Environmental
         Laws, or any act or omission causing an environmental condition that
         requires remediation or would allow any Governmental Authority to
         record a Lien on the land records, or

                  (e) any residual contamination on or under any of the Land, or
         affecting any natural resources, and to any contamination of any
         property or natural resources arising in connection with the
         generation, use, handling, storage, transport or disposal of any such
         Hazardous Substances, and irrespective of whether any of such
         activities were or will be undertaken in accordance with applicable
         laws, regulations, codes and ordinances;

provided, however, the Lessee shall not be required to indemnify any Indemnitee
under this Section 3 for (1) any Claim to the extent resulting from the willful
misconduct or gross negligence of such Indemnitee (2) any Claim to the extent
attributable to acts or events occurring prior to the Documentation Date or (3)
any Claim to the extent attributable to acts or events occurring after the
termination of the Master Lease, the expiration of the Term, the return of the
Property by the Lessee to the Lessor, or the remarketing of the Property so long
as the Lessor and the Lenders are not exercising remedies against the Lessee in
respect of the Operative Documents. It is expressly understood and agreed that
the indemnity provided for herein shall survive the expiration or termination of
and shall be separate and independent from any remedy under the Master Lease or
any other Operative Document.

                  XIII.4 Proceedings in Respect of Claims. With respect to any
amount that the Lessee is requested by an Indemnitee to pay by reason of Section
1 or 3, such Indemnitee shall, if so requested by the Lessee and prior to any
payment, submit such additional information to the Lessee as the Lessee may
reasonably request and which is in the possession of such Indemnitee to
substantiate properly the requested payment.

         In case any action, suit or proceeding shall be brought against any
Indemnitee or any Indemnitee receives written notice

                                      -40-
   73
of any threatened action, suit or proceeding, such Indemnitee shall with
reasonable promptness notify the Lessee of the commencement thereof, and the
Lessee shall be entitled, at its expense, to participate in, and, to the extent
that the Lessee desires to, assume and control the defense thereof; provided,
however, that the Lessee shall have acknowledged in writing its obligation to
fully indemnify such Indemnitee in respect of such action, suit or proceeding,
and, the Lessee shall keep such Indemnitee fully apprised of the status of such
action, suit or proceeding and shall provide such Indemnitee with all informa-
tion with respect to such action, suit or proceeding as such Indemnitee shall
reasonably request, and provided, further, that the Lessee shall not be entitled
to assume and control the defense of any such action, suit or proceeding if and
to the extent that, (A) in the reasonable opinion of such Indemnitee, (x) such
action, suit or proceeding involves any risk of imposition of criminal liability
or will involve any material risk of the sale, forfeiture or loss of the
Property or any part thereof or (y) the control of such action, suit or
proceeding would involve an actual or potential conflict of interest, (B) such
proceeding involves Claims not fully indemnified by the Lessee which the Lessee
and the Indemnitee have been unable to sever from the indemnified claim(s), or
(C) a Lease Event of Default has occurred and is continuing. The Indemnitee will
join in the Lessee's efforts to sever such action. The Indemnitee may
participate in a reasonable manner at its own expense and with its own counsel
in any proceeding conducted by the Lessee in accordance with the foregoing. The
Lessee shall not enter into any settlement or other compromise with respect to
any Claim which is entitled to be indemnified under Section 1 or 3 without the
prior written consent of the Indemnitee, which consent shall not be unreasonably
withheld in the case of a money settlement not involving an admission of
liability of such Indemnitee; provided, however, that in the event that such
Indemnitee withholds consent to any settlement or other compromise, the Lessee
shall not be required to indemnify such Indemnitee under Section 1 or 3 to the
extent that the applicable Claim results in a judgment in excess of such offered
money settlement.

         Each Indemnitee shall, at the expense of the Lessee, with reasonable
promptness supply the Lessee with such information and documents reasonably
requested by the Lessee as are necessary or advisable for the Lessee to
participate in and, to the extent permitted hereunder, control, any action, suit
or proceeding to the extent permitted by Section 1 or 3. Unless a Lease Event of
Default (other than a Lease Event of Default arising under Section 16.1(e) of
the Master Lease) shall have occurred and be continuing, no Indemnitee shall
enter into any settlement or other compromise with respect to any Claim which is
entitled to be indemnified under Section 1 or 3 without the prior written
consent of the Lessee, which consent shall not be unreasonably withheld, unless
such Indemnitee waives its right

                                      -41-
   74
to be indemnified under Section 1 or 3 with respect to such Claim.

         Upon payment in full of any Claim by the Lessee pursuant to Section 1
or 3 to or on behalf of an Indemnitee, the Lessee, without any further action,
shall be subrogated to any and all claims that such Indemnitee may have relating
thereto (other than claims in respect of insurance policies maintained by such
Indemnitee at its own expense), and such Indemnitee shall execute such
instruments of assignment and conveyance, evidence of claims and payment and
such other documents, instruments and agreements as may be necessary to preserve
any such claims and otherwise cooperate with the Lessee and give such further
assurances as are necessary or advisable to enable the Lessee vigorously to
pursue such claims.

         Any amount payable to an Indemnitee pursuant to Section 1 or 3 shall be
paid to such Indemnitee promptly upon receipt of a written demand therefor from
such Indemnitee, accompanied by a written statement describing in reasonable
detail the basis for such indemnity and the computation of the amount so
payable.

                  XIII.5 General Tax Indemnity.

         (a) If any Impositions (including, solely for purposes of this Section
5, (i) taxes based on, or measured by the net income of a Tax Indemnitee imposed
by the United States (or any state or other jurisdiction, political subdivision
or taxing authority thereof or therein) to the extent they would not have been
imposed if on each Acquisition Date or Funding Date, as the case may be, the Tax
Indemnitee had advanced funds directly to the Lessee in the form of a loan
secured by the applicable Property in an amount equal to the amount advanced for
the Property Costs on such Acquisition Date or Funding Date, as the case may be,
with the debt service for such loan equal to the Basic Rent payable on each
Scheduled Payment Date and a principal balance at the making of such loan in an
amount equal to the then outstanding amount of the Loans and Certificate Amounts
at the end of the term of the Master Lease, and (ii) taxes imposed with respect
to the payment, receipt or accrual of any indemnity payment hereunder, (net of
any tax benefit) are now or hereafter imposed or levied by the United States (or
by any state or other jurisdiction, political subdivision or taxing authority
thereof or therein) on any payments made by the Lessee hereunder or payable in
respect of a Loan or a Equity Amount or otherwise under the Master Lease or the
other Operative Documents to which it is a party or payments relating to the
ownership, lease, sale or use of the Property, then the Lessee shall pay such
additional amounts (at the time of such payment) as may be necessary so that
every payment of all amounts due hereunder or under such other Operative
Document, after withholding or deduction for or on account of any such
Impositions, will not be less than the amount provided for herein or therein.
The Tax Indemnitee shall promptly notify

                                      -42-
   75
the Lessee in writing of the occurrence of any event of which the Tax Indemnitee
has knowledge that will give rise to the obligation of the Lessee to pay such
additional amounts pursuant to this Section 5. As soon as practicable after the
date the payment of any Impositions is due pursuant to Applicable Law, the
Lessee shall furnish to the Tax Indemnitee certified copies of any tax receipts
obtained by the Lessee, evidencing payment by the Lessee and compliance with
this Section 5.

         (b) Should any Tax Indemnitee ever receive any refund, credit or
deduction from any taxing authority (whether before or after payment in full of
all amounts owed hereunder and under the Master Lease) to which such Tax
Indemnitee would not be entitled but for the payment by the Company of
additional amounts as required by this Section 5, such Tax Indemnitee (as
applicable) thereupon shall repay to the Lessee an amount with respect to such
refund, credit or reduction equal to any net reduction in Impositions actually
obtained by such Tax Indemnitee and reasonably determined by such Tax Indemnitee
to be directly related to such refund, credit or reduction (but not to exceed
such additional amounts to which such refund, credit or reduction relates). No
such payment shall be required, however, to the extent the Lessee is delinquent
in any payments to such Tax Indemnitee under this Participation Agreement, the
Master Lease or any other Operative Document, but shall promptly be paid to the
Lessee after such delinquency no longer exists. Notwithstanding the provisions
of this Section b to the contrary, the decision as to whether or not to claim
any such refund, credit or reduction (and if claimed, the determination of the
amount of the net reduction in Impositions attributable to the additional
amounts paid by the Lessee under this Section 5) shall be made by each Tax
Indemnitee (as applicable) in its sole discretion; provided, however, that each
Tax Indemnitee shall, if requested by the Lessee, use reasonable efforts to
claim any such material refund, material credit or material reduction.

         (c) The Lessee shall have the right to replace any Lender or the Lessor
that claims or requests payments pursuant to this Section 5. Any such
replacement shall be on terms and conditions substantially consistent with the
assignment provisions set forth in Section 1 of this Participation Agreement.
The agreements and obligations contained in this Section 5 shall survive the
payment in full of the Lessee's obligations hereunder and under the other
Operative Documents.

         (d) Tax Ownership. Each Participant represents and warrants that it
will not, prior to the termination of the Master Lease with respect to each
Property, claim ownership of (or any tax benefits, including depreciation, with
respect to) the Property for any income tax purposes, it being understood that
the Lessee is and will remain the owner of the Property for such income tax
purposes until the termination of the Master Lease with respect to each
Property. If, notwithstanding the

                                      -43-
   76
income tax intentions of the parties as set forth in this Section d and in
Section 1 hereof, any Participant actually receives any income tax deductions,
reductions in income tax or other income tax benefit as a result of any claim
for, or recharacterization requiring such party to take, any tax benefits
attributable to ownership of the Property for income tax purposes, such
Participant shall pay to the Lessee, together with an amount equal to any
reduced Taxes payable by such Tax Indemnitee as a result of such payment, the
amount of such income tax savings actually realized by such Participant (less
the amount of any anticipated increase in income tax which the Participant
determines is currently payable as a result of such claim or
recharacterization), provided that the Lessee shall agree to reimburse such
Participant for any subsequent increase in such Participant's income taxes
resulting from such claim or recharacterization not taken into account in the
payment made to the Lessee, up to the amount paid to the Lessee by such
Participant. The parties agree that this Section d is intended to require a
payment to the Lessee if and only if a Participant shall have actually received
an unanticipated tax savings with respect to a Property that would not have been
received if the Lessor had advanced funds to the Lessee in the form of a loan
secured by any of the Properties in an amount equal to the applicable Property
Costs. Nothing in this Section d shall be construed to require a Participant to
take any affirmative action to realize any tax savings if in its good faith
judgment such action may have a material adverse affect on such Participant.

                  XIII.6 Indemnity Payments in Addition to Master Lease
Obligations. The Lessee acknowledges and agrees that the Lessee's obligations to
make indemnity payments under this Section 13 are separate from, in addition to,
and do not reduce, the Lessee's obligation to pay under the Master Lease that
portion of the Lease Balance constituting the Loan Balance.

                  XIII.7 LIBO Rate Lending Unlawful. If the introduction of or
any change in or in the interpretation of any law makes it unlawful, or any
central bank or other governmental authority asserts that it is unlawful, for a
Participant to make, continue or maintain any Loan or Equity Amount, as the case
may be, the obligation of such Participant to make, continue or maintain any
such Loan or Equity Amount, as the case may be, shall, upon such determination,
forthwith be suspended until such Participant shall notify the Lessee and the
Lessor that the circumstances causing such suspension no longer exist and, to
the extent required by any such introduction of or change in or in the
interpretation of any law, all Loans or Equity Amounts, as the case may be, of
such Participant shall automatically bear interest or accrue Equity Yield at the
Alternate Base Rate either (a) on the last day of the then current Interest
Period applicable to such Loan or Equity Amount, as the case may be, if such
Participant may lawfully continue to maintain and fund such loan or Equity
Amount or (b) immediately if such Participant

                                      -44-
   77
shall determine that it may not lawfully continue to maintain and fund such Loan
or Equity Amount, as the case may be, to such day thereto or sooner, if required
by such law or assertion.

                  XIII.8 Deposits unavailable. If any of the Participants shall
have determined that

                  (i) Dollar deposits in the relevant amount and for the
         relevant Interest Period are not available after reasonable inquiry to
         the Participant in its relevant market; or

                  (ii) by reason of circumstances affecting the Participant's
         relevant market, adequate means do not exist for ascertaining the
         interest rate or Equity Yield, as the case may be, applicable to such
         Participant's Loans or Equity Amounts,

then, upon notice from such Participant to the Lessee and the other
Participants, (i) the obligations of the Participants to make Loans or Equity
Amounts, as the case may be, shall be suspended and (ii) each outstanding Loan
or Equity Amount, as the case may be, shall begin to bear interest or accrue
Equity Yield at the Alternate Base Rate on the last day of the then current
Interest Period applicable thereto.

                  XIII.9 Increased costs, etc. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority increases or would increase the cost to any
Participant of, or reduces or would reduce the amount of any sum receivable by
such Participant in respect of, making, continuing or maintaining (or of its
obligation to make, continue or maintain) any Loans or Equity Amounts, as the
case may be, the Lessee agrees to reimburse such Participant for each such
increased cost or reduced amount when applicable to such Participant. Such
Participant shall promptly notify the Lessor, and the Lessee in writing of the
occurrence of any such event, such notice to state, in reasonable detail, the
reasons therefor and the additional amount required fully to compensate such
Participant for such increased cost or reduced amount. Such additional amounts
shall be payable by the Lessee directly to such Participant within five days of
its receipt of such notice, and such notice shall be presumed correct and
binding on the Lessee absent demonstrable error. The Lessee's liability under
this Section 13.9 shall be subject to the delivery of such notice by Participant
described above within six (6) months after such Participant has first
conclusively determined that such reimbursement or compensation is due such
Participant.

                  XIII.10 Funding losses. In the event any Participant shall
incur any loss or out-of-pocket expense (including any

                                      -45-
   78
loss or out-of-pocket expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Participant) to make,
continue or maintain any portion of the principal amount of any Loan or Equity
Amount, as the case may be, as a result of:

                  (a) any conversion or repayment or prepayment of the principal
         amount of any Loans or Equity Amounts on a date other than the
         scheduled last day of the Interest Period applicable thereto; or

                  (b) any Loans or Equity Amounts, as the case may be, not being
         made in accordance with the Funding Request therefor (unless such
         failure to make such Loans or Equity Amounts constitutes a breach by
         the applicable Participant of its obligations under Article III),

then, upon the written notice of such Participant to the Lessee (with a copy to
the Lessor), the Lessee shall, within five days of its receipt thereof, pay
directly to such Participant such amount (determined on the basis of such
Participant's standard practices) as will reimburse such Participant for such
loss or out-of-pocket expense. Such written notice (which shall include
calculations in sufficiently reasonable detail to indicate the incurrence and
amount of such loss and out-of-pocket expense) shall be presumed correct and
binding on the Lessee absent demonstrable error. The Lessee's liability under
this Section 13.10 shall be subject to the delivery of such notice by
Participant described above within six (6) months after such Participant has
first conclusively determined that such reimbursement or compensation is due
such Participant.

                  XIII.11 Increased Capital Costs. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other govern mental authority affects or would affect the amount of capital
required or expected to be maintained by any Participant or any Person
controlling such Participant, and such Participant reasonably determines that
the rate of return on its or such controlling Person's capital as a consequence
of its Commitment or the Loans or Equity Amounts, as the case may be, made by
such Participant is reduced to a level below that which such Participant or such
controlling Person could have achieved but for the occurrence of any such
circumstance, then, in any such case upon notice from time to time by such
Participant to the Lessee, the Lessee shall immediately pay directly to such
Participant additional amounts sufficient to compensate such Participant or such
controlling Person for such reduction in rate of return. A statement of such
Participant as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall be presumed correct and binding on the

                                      -46-
   79
Lessee absent demonstrable error. In determining such amount, such Participant
shall use its standard practice in determining such amount, and, in the absence
of such standard practice, may use any reasonable method of averaging and
attribution that it shall deem applicable. The Lessee's liability under this
Section 13.11 shall be subject to the delivery of such notice by Participant
described above within six (6) months after such Participant has first
conclusively determined that such reimbursement or compensation is due such
Participant.

                                      XIV

                             The Participation Agent

         The Participation Agent, the Lessor and the Participants hereby agree
as follows:

                  XIV.1 Appointment. The Lessor and each Participant hereby
irrevocably designates and appoints the Participation Agent as the agent of such
party under this Participation Agreement and the other Operative Documents, and
the Lessor and each Participant irrevocably authorizes the Participation Agent,
in such capacity, to take such action on its behalf under the provisions of this
Participation Agreement and the other Operative Documents and to exercise such
powers and perform such duties as are expressly delegated to the Participation
Agent by the terms of this Participation Agreement and the other Operative
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Participation
Agreement, the Participation Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with the Lessor or any Participant or any other party to the
Operative Documents, and no implied covenants, functions, responsibilities,
duties, obligations or liabilities shall be read into this Participation
Agreement or any other Operative Document or otherwise exist against the
Participation Agent.

                  XIV.2 Delegation of Duties. The Participation Agent may
execute any of its duties under this Participation Agreement and the other
Operative Documents by or through agents or attorneys-in-fact and shall be
entitled to advice of counsel concerning all matters pertaining to such duties.
The Participation Agent shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

                  XIV.3 Exculpatory Provisions. Neither the Participation Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Participation
Agreement

                                      -47-
   80
or any other Operative Document (except for its or such Person's own gross
negligence or willful misconduct) or (b) responsible in any manner to any of the
Participants or any other party to the Operative Documents for any recitals,
statements, representations or warranties made by the Lessor or the Lessee or
any officer thereof contained in this Participation Agreement or any other
Operative Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Participation Agent under or
in connection with, this Participation Agreement or any other Operative Document
or for the value, validity, effectiveness, genuineness, enforceability or
sufficiency of this Participation Agreement or any other Operative Document or
for any failure of the Lessor or the Lessee to perform its obligations hereunder
or thereunder. The Participation Agent shall not be under any obligation to any
Participant or any other party to the Operative Documents to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Participation Agreement or any other Operative
Document, or to inspect the properties, books or records of the Lessor or the
Lessee.

                  XIV.4 Reliance by Participation Agent. The Participation Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
writing, resolution, notice, consent, certificate, affidavit, letter, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Lessor or the Lessee),
independent accountants and other experts selected by the Participation Agent.
The Participation Agent shall be fully justified in failing or refusing to take
any action under this Participation Agreement or any other Operative Document
unless it shall first receive such advice or concurrence of the Lessor and the
Required Participants as it deems appropriate and it shall first be indemnified
to its satisfaction by the Participants against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Participation Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Participation Agreement and
the other Operative Documents in accordance with a request of the Lessor and the
Required Participants, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Participants.

                  XIV.5 Notice of Default. The Participation Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default unless the Participation Agent has received notice from a Participant,
the Lessor or the Lessee describing such Default or Event of Default and stating
that such notice is a "notice of default." In the event that the Participation
Agent receives such a notice, the Participation

                                      -48-
   81
Agent shall give notice thereof to the other parties hereto. The Participation
Agent shall take such action with respect to such Default or Event of Default as
shall be reasonably directed by the Lessor and the Required Participants;
provided that unless and until the Participation Agent shall have received such
directions, the Participation Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the Lessor
and the Participants.

                  XIV.6 Non-Reliance on Participation Agent and Other
Participants. The Lessor and each Participant expressly acknowledges that
neither the Participation Agent nor any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates has made any representations or
warranties to it and that no act by the Participation Agent hereinafter taken,
including any review of the affairs of the Lessor or the Lessee, shall be deemed
to constitute any representation or warranty by the Participation Agent to any
Participant. Each Participant represents to the Participation Agent that it has,
independently and without reliance upon the Participation Agent or any other
Participant, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Lessor, the Lessee and the Property and made its own decision to enter into this
Participation Agreement. Each Participant also represents that it will,
independently and without reliance upon the Participation Agent, the Lessor or
any other Participant, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Participation
Agreement and the other Operative Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Lessor and the Lessee.
Except for notices, reports and other documents expressly required to be
furnished to the Participants by the Participation Agent hereunder, the
Participation Agent shall not have any duty or responsibility to provide any
Participant with any credit or other information concerning the business, opera-
tions, property, condition (financial or otherwise), prospects or
creditworthiness of the Lessor or the Lessee which may come into the possession
of the Participation Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates.

                  XIV.7 Indemnification. The Participants agree to indemnify the
Participation Agent in its capacity as such (to the extent not reimbursed by the
Lessee and without limiting the obligation of the Lessee to do so), ratably
according to their respective Commitment Percentages in effect on the date on
which indemnification is sought under this Section 7 (or, if

                                      -49-
   82
indemnification is sought after the date upon which the Commitments shall have
terminated and the Participation Interests shall have been paid in full, ratably
in accordance with their Commitment Percentages immediately prior to such date),
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time be imposed on, incurred by or asserted
against the Participation Agent in any way relating to or arising out of, the
Commitments, this Participation Agreement, the Property, any of the other
Operative Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by any of them under or in connection with any of the foregoing;
provided that no Participant shall be liable for the payment of any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from the gross
negligence or willful misconduct of the Participation Agent. The agreements in
this Section 7 shall survive the payment in full of the Participant Balance and
all other amounts payable hereunder.

                  XIV.8 Successor Participation Agent. The Participation Agent
may resign as Participation Agent upon twenty (20) days' notice to the
Participants, the Lessor and the Lessee. If the Participation Agent shall resign
as Participation Agent under this Participation Agreement and the other
Operative Documents, then Lessor and the Required Participants shall appoint a
successor agent for the Participants, which successor agent shall be a
commercial bank organized under the laws of the United States of America or any
State thereof or under the laws of another country which is doing business in
the United States of America and having a combined capital, surplus and
undivided profits of at least $500,000,000 and a debt rating of A (or its
equivalent) or better from Standard and Poor's Ratings Group and/or Moody's
Investors Service, Inc. (and if no Default or Event of Default exists, shall be
approved by the Lessee (which consent shall not be unreasonably withheld)),
whereupon such successor agent shall succeed to the rights, powers and duties of
the Participation Agent, and the term "Participation Agent" shall mean such
successor agent effective upon such appointment and approval, and the former
Participation Agent's rights, powers and duties as Participation Agent shall be
terminated, without any further act or deed on the part of such former
Participation Agent or any of the parties to this Participation Agreement. If no
successor Participation Agent has accepted appointment as Participation Agent by
the date which is twenty (20) days following a resigning Participation Agent's
notice of resignation, the resigning Participation Agent's resignation shall
nevertheless thereupon become effective and the Lessor and the Participants
shall perform all of the duties of the Participation Agent hereunder until such
time, if any, as the Lessor and the Lessor and the Required Participants appoint
a successor Participation Agent as provided above. After any

                                      -50-
   83
retiring Participation Agent's resignation as Participation Agent, all of the
provisions of this Article 0 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Participation Agent under this
Participation Agreement and the other Operative Documents.

                  XIV.9 Administrative Fee. At the end of each year calendar
year, the Lessee shall pay to the Participation Agent an administrative fee of
eight thousand dollars ($8,000).

                                       XV

                                  Miscellaneous

                  XV.1 Survival of Agreements. The representations, warranties,
covenants, indemnities and agreements of the parties provided for in the
Operative Documents, and the parties' obligations under any and all thereof,
shall survive the execution and delivery of this Participation Agreement, the
transfer of the Property to the Lessor, the construction of any Improvements,
any disposition of any interest of the Lessor in the Property or any
Improvements and the payment of the Notes and any disposition thereof shall
continue in effect notwithstanding any investigation made by any party and the
fact that any party may waive compliance with any of the other terms, provisions
or conditions of any of the Operative Documents. Except as otherwise expressly
set forth herein or in other Operative Documents, the indemnities of the parties
provided for in the Operative Documents shall survive the expiration or
termination of any thereof for a period not to exceed one year after the later
of (x) the Expiration Date and (y) the payment in full in cash of the Lease
Balance.

                  XV.2 No Broker, etc. Each of the parties hereto represents to
the others that it has not retained or employed any broker, finder or financial
adviser (other than The Industrial Bank of Japan, Limited or an Affiliate
thereof) to act on its behalf in connection with this Participation Agreement or
the transactions contemplated herein, nor has it authorized any broker, finder
or financial adviser retained or employed by any other Person so to act. Any
party who is in breach of this representation shall indemnify and hold the other
parties harmless from and against any liability arising out of such breach of
this representation.

                  XV.3 Notices. Unless otherwise specifically provided herein,
all notices, consents, directions, approvals, instructions, requests and other
communications required or permitted by the terms hereof to be given to any
Person shall be given in writing by United States mail, by nationally recognized
courier service, by hand or, in the case of Funding Requests, by facsimile, and
any such notice shall become effective upon the applicable party's receipt
thereof (or refusal to accept

                                      -51-
   84
receipt), and shall be directed to the address of such Person as indicated on
Schedule IV. From time to time any party may designate a new address for
purposes of notice hereunder by written notice to each of the other parties
hereto in accordance with this Section.

                  XV.4 Counterparts. This Participation Agreement may be
executed by the parties hereto in separate counterparts, each of which when so
executed and delivered shall be an original, but all such counterparts shall
together constitute but one and the same instrument.

                  XV.5 Amendments. (a) The provisions of this Participation
Agreement may from time to time be amended, modified or waived, provided that
such amendment, modification or waiver is in writing and consented to by the
Lessee, the Lessor, the Agent and the Required Participants; provided, however,
that no amendment or waiver of any provision relating to payment to or
indemnification of any Participant shall be effective against such Participant
unless it has been consented to in writing by such Participant.

         (b) Neither any Operative Document nor any of the terms thereof may be
terminated (except upon payment in full of the Lease Balance or effective
exercise and consummation of the Remarketing Option in accordance with Article
XX of the Master Lease and payment in full of all amounts due in accordance
therewith), amended, supplemented, waived or modified without the written
agreement or consent of each party thereto and, regardless of whether the
Lenders and the Lessor are parties thereto, the Required Participants; provided,
however, that:

                  (x) no such termination, amendment, supplement, waiver or
         modification shall without written agreement or consent of each
         Participant:

                  (i) modify any of the provisions of this Section 5, change the
         definition of "Required Participants" or modify or waive any provision
         of an Operative Agreement requiring action by each Participant;

                  (ii) amend, modify, waive or supplement any of the provisions
         of Section 2.6, 2.7 or 2.8 of the Loan Agreement;

                  (iii) reduce, modify, amend or waive any fees or indemnities
         in favor of any Participant, including without limitation amounts
         payable pursuant to Article XIII (except that any Person may consent to
         any reduction, modification, amendment or waiver of any indemnity
         payable to it);

a court and any claim that any such proceeding brought in such a court has been
brought in an inconvenient forum.

any and all other rights and remedies available at law or in equity, to require
such Lender to assign and delegate in accordance with Section 1 all of such
Lender's total Loans and Commitment to any of the Lenders or to any other

Collateral, and all rights to payment with respect to any cause of action
affecting or relating to the Collateral).

The pledge, assignment and grant of a security interest made by Lessee hereunder
is for security of the Loan Obligations only. The parties hereto do not intend
for the Collateral to constitute advance payment of any Obligations or
liquidated damages nor do the parties intend for the Collateral to increase the
Obligations owed by Lessee to Lessor under the Operative Documents.

         3. Delivery and Maintenance of Cash Collateral. Lessee shall deliver
Cash Collateral only to, and Cash Collateral may be maintained only by, a
Depositary Bank, subject to the following terms and conditions:

         (a) No Lender may, at any time, hold Cash Collateral having a Value
which exceeds such Lender's Commitment Percentage of the aggregate Value of all
Cash Collateral held by all Depositary Banks at such time.

         (b) No Person may act as a Depositary Bank hereunder unless at or prior
to the time such Person is to receive its initial delivery of Cash Collateral,
such Person has become a party to this Cash Collateral Agreement by completing,
executing and delivering to Lessee and the Participation Agent a Supplement in
the form of Attachment 1.


                                      -3-
   132
         (c) No Depositary Bank may maintain Cash Collateral in any Account
unless, at or prior to the time such Depositary Bank receives Cash Collateral
for inclusion in such Account:

                  (i) the Participation Agent and Lessee have completed,
         executed and delivered to such Depositary Bank a Notice of Security
         Interest in the form of Attachment 2 (a "Notice of Security Interest")
         which specifically identifies such Account; and

                  (ii) such Depositary Bank has executed the Acknowledgement and
         Agreement at the end of such Notice of Security Interest and returned
         the same to the Participation Agent.

         (d) Unless a Default or an Event of Default has occurred and is
continuing, Lessee shall direct each Depositary Bank holding Cash Collateral to
hold such Cash Collateral in the form of certificates of deposit issued by such
Depositary Bank or time deposit accounts of such Depositary Bank and the term of
each such investment (each, a "Term") shall be for consecutive one (1) month or
three (3) month periods; provided, however, that any such period shall end on
the last day of each Interest Period. If a Default or an Event of Default has
occurred and is continuing, all Cash Collateral shall, at the end of the current
terms of all investments thereof, be maintained in time deposit accounts with
terms not exceeding one (1) week. Each such certificate of deposit or time
deposit account shall bear interest on each Payment Date in an amount at least
equal to the LIBO Rate (Reserve Adjusted) for the Loans due and owing on such
Payment Date. Such interest shall be applied in accordance with Section 4.5 of
the Participation Agreement.

         (e) Lessee and the Participation Agent agree that (i) the possession by
a Depositary Bank of any money, instruments, chattel paper or other property
constituting Collateral or evidencing Collateral shall be deemed to be
possession by the Participation Agent or a person designated by the
Participation Agent, for purposes of perfecting the security interest granted to
the Participation Agent hereunder pursuant to Section 9305 of the Uniform
Commercial Code and (ii) notifications to a Depositary Bank by other Persons
holding any such property, and acknowledgements, receipts or confirmations from
any such Persons delivered to a Depositary Bank, shall be deemed notifications
to, or acknowledgements, receipts or confirmations from, financial
intermediaries, bailees or agents (as applicable) of such Depositary Bank for
the benefit of the Participation Agent for the purposes of perfecting such
security interests under applicable law.

         (f) All amounts of Cash Collateral held in one or more Accounts shall
be amounts payable in Dollars.


                                      -4-
   133
         4. Withdrawal of Cash Collateral. Lessee may not withdraw Cash
Collateral from a Depositary Bank, except as follows:

         (a) If the representations and warranties of any Depositary Bank set
forth in Subparagraph 5(b) cease to be true and correct at any time, Lessee or
the Participation Agent may direct such Depositary Bank to transfer all Cash
Collateral then held by such Depositary Bank to the Participation Agent to be
held by the Participation Agent pursuant to this Cash Collateral Agreement. If
the representations and warranties of the Participation Agent, as a Depositary
Bank, set forth in Subparagraph 5(b) cease to be true and correct at any time,
Lessee may direct the Participation Agent to transfer all Cash Collateral then
held by the Participation Agent to another Depositary Bank to be held by such
Depositary Bank pursuant to this Cash Collateral Agreement and, in such case,
the amount limitation for such other Depositary Bank set forth in Subparagraph
3(a) shall be suspended.

         (b) If no Default or Event of Default has occurred and is continuing,
Lessee may withdraw Cash Collateral from any Depositary Bank, free and clear of
all liens and security interests hereunder, provided that:

                  (i) such withdrawal (together with any substantially
         concurrent withdrawals of Cash Collateral from other Depositary Banks)
         does not cause the Value of the Cash Collateral then held by the
         Depositary Bank to be less than the current Loan Balance;

                  (ii) the Lessee gives such Depositary Bank and the
         Participation Agent at least three (3) Business Days prior written
         notice of such withdrawal; and

                  (iii) the Lessee shall not make more than three (3)
         withdrawals from each Depositary Bank in any calendar quarter.

If Lessee withdraws any Cash Collateral from an Account prior to the last day of
any Term thereof, Lessee shall pay to the Depositary Bank at which such Account
was maintained all applicable early withdrawal penalties and other breakage
charges specified at or prior to the time such Account was initially
established.

         5. Representations and Warranties.

         (a) Lessee represents and warrants to Lessor and the Participation
Agent as follows:

                  (i) Lessee is the legal and beneficial owner of the Collateral
         (or, in the case of after-acquired


                                      -5-
   134
         Collateral, at the time Lessee acquires rights in the Collateral, will
         be the legal and beneficial owner thereof). No other Person has (or in
         the case of after-acquired Collateral, at the time Lessee acquires
         rights therein, will have) any right, title, claim or interest (by way
         of Lien, purchase option or otherwise) in, against or to the
         Collateral.

                  (ii) The Participation Agent has (or in the case of
         after-acquired Collateral, at the time Lessee acquires rights therein,
         will have) a first priority perfected security interest in the
         Collateral.

                  (iii) Lessee has delivered to the Participation Agent,
         together with all necessary stock powers, endorsements, assignments and
         other necessary instruments of transfer, the originals of all
         documents, instruments and agreements evidencing Cash Collateral.

                  (iv) Lessee's chief executive office is located at 4650
         Cushing Parkway, Fremont, California 94538.

         (b) Each Depositary Bank represents and warrants to Lessee and the
Participation Agent as follows:

                  (i) Such Depositary Bank is a commercial bank organized under
         the laws of the United States of America or a State thereof or under
         the laws of another country which is doing business in the United
         States of America and has the power to issue and maintain Accounts.

                  (ii) Such Depositary Bank has a combined capital, surplus and
         undivided profits of at least $500,000,000.

                  (iii) With respect to each Notice of Security Interest
         acknowledged by such Depositary Bank, at the time of such
         acknowledgement (A) the information regarding Account(s) maintained by
         such Depositary Bank which is set forth in such Notice of Security
         Interest will be accurate, (B) such Account(s) will be currently open,
         (C) certificates of deposit or time deposit accounts of the type
         contemplated by this Cash Collateral Agreement are and will be
         available to the Lessee, and (D) Depositary Bank will have no prior
         notice of any other security interest, Lien or interest in such
         Account(s).

                  (iv) All actions necessary to perfect the security interest of
         the Participation Agent in each Account established or maintained by
         such Depositary Bank will have been taken under the laws of the


                                      -6-
   135
         jurisdiction in which the applicable Account Office(s) is (are) located
         at or prior to the time such Depositary Bank acknowledges the Notice of
         Security Interest relating to such Account.

         6. Covenants.

         (a) Lessee hereby agrees as follows:

                  (i) Lessee, at Lessee's expense, shall promptly procure,
         execute and deliver to the Participation Agent all documents,
         instruments and agreements and perform all acts which are necessary or
         desirable, or which the Participation Agent may request, to establish,
         maintain, preserve, protect and perfect the Collateral, the security
         interest granted to the Participation Agent therein and the first
         priority of such security interest or to enable the Participation Agent
         to exercise and enforce its rights and remedies hereunder with respect
         to any Collateral. Without limiting the generality of the preceding
         sentence, Lessee shall (A) procure, execute and deliver to the
         Participation Agent all stock powers, endorsements, assignments,
         financing statements and other instruments of transfer requested by
         the Participation Agent and (B) deliver to the Participation Agent
         promptly upon receipt all originals of Collateral consisting of
         instruments, documents and chattel paper.

                  (ii) Lessee shall not use or permit any Collateral to be used
         in violation of (A) any provision of the Participation Agreement, this
         Cash Collateral Agreement or any other Operative Document or (B) any
         Applicable Law where such use might have a Material adverse effect.

                  (iii) Lessee shall pay promptly when due all taxes and other
         governmental charges, all liens and all other charges now or hereafter
         imposed upon, relating to or affecting any Collateral.

                  (iv) Without thirty (30) days' prior written notice to the
         Participation Agent, Lessee shall not change Lessee's name or place of
         business (or, if Lessee has more than one place of business, its chief
         executive office).

                  (v) For each time deposit account and certificate of deposit
         maintained by Lessee pursuant to this Cash Collateral Agreement, Lessee
         shall (A) execute and deliver to the Depository Bank at which such
         Account is maintained a Notice of Security Interest in the form of
         Attachment 2 hereto and (B) cause the Depositary Bank to execute and
         deliver


                                      -7-
   136
         to the Participation Agent an Acknowledgment and Agreement in the form
         set forth in such Notice of Security Interest.

                  (vi) Lessee shall appear in and defend any action or
         proceeding which may affect its title to or the Participation Agent's
         interest in the Collateral.

                  (vii) Subject to Lessee's withdrawal rights hereunder, Lessee
         shall not surrender or lose possession of (other than to the
         Participation Agent or a Depositary Bank pursuant hereto), sell,
         encumber, lease, rent, option, or otherwise dispose of or transfer any
         Collateral or right or interest therein except as permitted in the
         Participation Agreement, and, notwithstanding any provision of the
         Participation Agreement, Lessee shall keep the Collateral free of all
         Liens.

         (b) Each Depositary Bank hereby agrees as follows:

                  (i) Such Depositary Bank shall notify Lessee, Lessor and the
         Participation Agent if the representations and warranties made by such
         Depositary Bank pursuant to the Supplement signed by such Depositary
         Bank and in Subparagraph 5(b) hereof cease to be true and correct.

                  (ii) Such Depositary Bank shall hold all Cash Collateral and
         other Collateral received by it for the Participation Agent and as the
         Participation Agent's bailee.

                  (iii) Such Depositary Bank shall make a notation in its books
         and records of the Participation Agent's interest in the Collateral
         held by such Depositary Bank.

                  (iv) Such Depositary Bank shall take such other steps as the
         Participation Agent may reasonably request to perfect its security
         interest in the Collateral held by such Depositary Bank. Prior to its
         receipt of any Cash Collateral to be maintained in an Account, such
         Depositary Bank shall notify the Participation Agent of any steps which
         must be taken under the laws of the jurisdiction in which the
         applicable Account Office(s) is (are) located to perfect the
         Participation Agent's security interest in such Account.

                  (v) Upon receipt of notice from the Participation Agent that
         an Event of Default has occurred, such Depositary Bank shall transfer
         and deliver to the Participation Agent or its nominee,


                                      -8-
   137
         together with all necessary endorsements, all or such portion of the
         Collateral as the Participation Agent shall direct.

         7. Authorized Action by the Participation Agent. Lessee hereby
irrevocably appoints the Participation Agent as its attorney-in-fact and agrees
that the Participation Agent may perform (but the Participation Agent shall not
be obligated to and shall incur no liability to Lessee or any third party for
failure so to do) any act which Lessee is obligated by this Cash Collateral
Agreement to perform, and to exercise such rights and powers as Lessee might
exercise with respect to the Collateral, including, without limitation, the
right to (a) collect by legal proceedings or otherwise and endorse, receive and
receipt for all dividends, interest, payments, proceeds and other sums and
property now or hereafter payable on or on account of the Collateral; (b) enter
into any extension, reorganization, deposit, merger, consolidation or other
agreement pertaining to, or deposit, surrender, accept, hold or apply other
property in exchange for the Collateral; (c) insure, process, preserve and
enforce the Collateral; (d) pay any indebtedness of Lessee relating to the
Collateral; and (e) execute UCC financing statements and other documents,
instruments and agreements required hereunder; provided, however, that the
Participation Agent may not exercise such powers unless an Event of Default has
occurred and is continuing. Lessee agrees to reimburse the Participation Agent
upon demand for all reasonable costs and expenses, including attorneys' fees,
the Participation Agent may incur while acting as Lessee's attorney-in-fact
hereunder, all of which costs and expenses are included in the Loan Obligations.
Lessee agrees that such care as the Participation Agent gives to the safekeeping
of its own property of like kind shall constitute reasonable care of the
Collateral when in the Participation Agent's possession; provided, however, that
the Participation Agent shall not be required to make any presentment, demand or
protest, or give any notice and need not take any action to preserve any rights
against any prior party or any other Person in connection with the Loan
Obligations or with respect to the Collateral.

         8. Default and Remedies. Lessee shall be deemed in default under this
Cash Collateral Agreement upon the occurrence and during the continuance of an
Event of Default, as that term is defined in Appendix A to the Participation
Agreement. In addition to all other rights and remedies granted to the
Participation Agent by this Cash Collateral Agreement, the Participation
Agreement, the other Operative Documents, the UCC and other Applicable Laws, the
Participation Agent may, upon the occurrence and during the continuance of any
Event of Default, exercise any one or more of the following rights and remedies:

         (a) the Participation Agent may collect, receive, appropriate or
realize upon the Collateral or otherwise foreclose or enforce the Participation
Agent's security


                                      -9-
   138
interests in any or all Collateral in any manner permitted by Applicable Law or
in this Cash Collateral Agreement to the extent permitted by Applicable Law;

         (b) the Participation Agent may notify the Depositary Bank to pay all
or any portion of the Collateral held by the Depositary Bank directly to the
Participation Agent; or

         (c) the Depositary Bank may, but only with the prior written
authorization of the Participation Agent, setoff any or all amounts owed by
Depositary Bank to Lessee on account of Collateral held by Depositary Bank
against the portion of the Obligations owed to Depositary Bank;

The Participation Agent shall distribute the proceeds of all Collateral received
by the Participation Agent after the occurrence of an Event of Default to Lessor
for application to the Loan Obligations owed to the Lessor pursuant to the
Participation Agreement. If any proceeds of Collateral remain after all Loan
Obligations have been paid in full, the Participation Agent and the Depositary
Bank holding such proceeds shall deliver the same to Lessee or other Person
entitled thereto. In any case where notice of any sale or disposition of any
Collateral is required, Lessee hereby agrees that seven (7) days notice of such
sale or disposition is reasonable.

         Notwithstanding the foregoing, in the event Lessee shall exercise its
Early Purchase Option under the Master Lease or should otherwise be obligated to
purchase one or more of the Properties under the Master Lease, the Participation
Agent shall distribute the proceeds of any and all Collateral to apply to the
purchase price for such Property at the time of closing of the purchase of such
Property, provided, however, that Lessee shall pay all other costs or expenses
then due and owing on the sale of such Property. Nothing contained in this Cash
Collateral Agreement shall limit Lessee's right to exercise its Early Purchase
Option pursuant to Section 18.1 of the Master Lease following an Event of
Default.

         Notwithstanding the foregoing, upon the exercise of any remedy by the
Lessor after an Event of Default has occurred, which remedy shall subject the
Lessee to the payment of the Loan Balance or Recourse Amount, the Participation
Agent shall distribute the proceeds of any and all Collateral to the Lessor to
apply to the payment of such Loan Balance or Recourse Amount.

         Notwithstanding the foregoing or any other term or provision contained
in this Cash Collateral Agreement, the Participation Agent shall have no right
to exercise any remedies against the Collateral with respect to the Tranche B
Obligations unless a Lease Event of Default (other than a Financial Covenant
Event of Default) or a Construction Agency Event of Default with respect to
Section 5.1(a) of the Construction Agency Agreement


                                      -10-
   139
has occurred. Notwithstanding the foregoing, or any other term or provision of
this Cash Collateral Agreement, on the Expiration Date, if Lessee has elected
not to purchase the Properties pursuant to Section 18.2 of the Master Lease, the
Participation Agent shall have no right to exercise any remedies against the
Collateral with respect to the Tranche B Obligations unless a Lease Event of
Default has occurred with respect to Section 16.1(a), (b), (g) or (h) of the
Master Lease. In the event of any inconsistency between the immediately
preceding two sentences and any other provision of this Cash Collateral
Agreement, the terms of the immediately two preceding sentences shall prevail
and the Participation Agent's rights under this Cash Collateral Agreement shall
be limited as specified in such two immediately preceding sentences.

         Notwithstanding anything to the contrary in the Operative Documents,
(a) Lessee's obligation to make any payment on account of any Obligation under
any of the Operative Documents shall be exonerated to the extent that the Lessee
or any other Person shall have tendered, following any Lease Event of Default or
Construction Agency Agreement Event of Default full and final payment of a like
amount to the Participation Agent or the Lessor pursuant to the Operative
Documents, and (b) that in no event shall Lessee be liable for any failure by
the Lessor to pay any amounts to the Participation Agent or the Lenders, nor
shall Lessee be liable for the unenforceability of the Obligations of the Lessor
or the Lessee as a result of any of the following: (i) any act, omission,
misrepresentation or breach of warranty of the Lessor (including without
limitation, any fraud, negligence or misapplication of funds by the Lessor)
except for a failure by the Lessor to pay to the extent caused by a Lease Event
of Default or Construction Agency Agreement Event of Default; (ii) the filing by
or against the Lessor of any insolvency, bankruptcy, dissolution, liquidation,
reorganization or similar proceedings; (iii) the making by the Lessor of any
assignment for the benefit of creditors; (iv) the appointment of a trustee,
custodian or receiver for the Lessor or with respect to its assets; (v) the
granting or creation, whether voluntary or involuntary, of any lien by the
Lessor upon the payments due to the Lessor under the Master Lease (other than in
favor of the Participation Agent or the Participants) or any foreclosure or
other sale pursuant thereto; or (vi) the execution by any judgment creditor of
the Lessor of any judgment lien upon the payments due to the Lessor under the
Master Lease. Notwithstanding anything to the contrary in the Operative
Documents, in no event shall the Participation Agent exercise any right of
offset or appropriation or otherwise exercise any of its rights with respect to
the Collateral (i) with resect to any amount due on account of any Obligations
to the extent that the Lessee or any other Person shall have tendered, following
any Lease Event of Default or Construction Agency Agreement Event of Default,
full and final payment of a like amount to the Participation Agent or the Lessor
pursuant to the Operative Documents (it being understood that the Participation
Agent


                                      -11-
   140
shall not be limited in any way from exercising any of its remedies prior to the
date such payment shall have been made); or (ii) on account of any amount due as
a result of any of the events described in the immediately preceding sentence.

         9. Miscellaneous.

         (a) Notices. Except as otherwise specified herein, all notices,
requests, demands, consents, instructions or other communications to or upon
Lessee or the Participation Agent under this Cash Collateral Agreement shall be
given as provided in Schedule IV of the Participation Agreement.

         (b) Waivers; Amendments. Any term, covenant, agreement or condition of
this Cash Collateral Agreement may be amended or waived only as provided in the
Participation Agreement. No failure or delay by the Participation Agent in
exercising any right hereunder shall operate as a waiver thereof or of any other
right nor shall any single or partial exercise of any such right preclude any
other further exercise thereof or of any other right. Unless otherwise specified
in any such waiver or consent, a waiver or consent given hereunder shall be
effective only in the specific instance and for the specific purpose for which
given.

         (c) Successors and Assigns. This Cash Collateral Agreement shall be
binding upon and inure to the benefit of Lessee, the Participation Agent and the
Depositary Bank which become parties hereto and their respective permitted
successors and assigns.

         (d) Partial Invalidity. If at any time any provision of this Cash
Collateral Agreement is or becomes illegal, invalid or unenforceable in any
respect under the law or any jurisdiction, neither the legality, validity or
enforceability of the remaining provisions of this Cash Collateral Agreement nor
the legality, validity or enforceability of such provision under the law of any
other jurisdiction shall in any way be affected or impaired thereby.

         (e) Cumulative Rights, etc. The rights, powers and remedies of the
Participation Agent under this Cash Collateral Agreement shall be in addition to
all rights, powers and remedies given to the Participation Agent by virtue of
any Applicable Law, the Participation Agreement, any other Operative Document or
any other agreement, all of which rights, powers, and remedies shall be
cumulative and may be exercised successively or concurrently without impairing
the Participation Agent's rights hereunder. Lessee waives any right to require
the Participation Agent to proceed against any Person or to exhaust any
Collateral or to pursue any remedy in the Participation Agent's or such
Participant's power.


                                      -12-
   141
         (f) Governing Law. This Cash Collateral Agreement shall be governed by
and construed in accordance with the laws of the State of California without
reference to conflicts of law rules (except to the extent otherwise provided in
the UCC).

         IN WITNESS WHEREOF, the parties hereto have caused this Cash Collateral
Agreement to be executed as of the day and year first above written.

Assignor's obligations under the Loan Agreement and the Notes and the execution
and delivery hereof shall not impair or diminish in any way the obligations of
the Assignor under the Assigned Leases or any Other Lease, or impose any of such
obligations on the Participation Agent or the Lenders. This Assignment shall not
operate to cause the Participation Agent or the Lenders (or their designee) to
be regarded as a mortgagee in possession. Neither the Participation Agent, the
Lenders nor their designee shall be responsible or liable for performing any of
the


                                      -6-
   154
obligations of the Assignor under any of the Assigned Leases, any Other Leases
or any Contract, for any waste by the Lessee or others, for any dangerous or
defective conditions of any Property, for negligence in the management, upkeep,
repair or control of any Property or any other act or omission by any other
Person. Nothing contained herein shall operate or be construed to (i) obligate
the Participation Agent or the Lenders (or their designee) to assume the
obligations of the Assignor under any of the Assigned Leases, any Other Lease or
any Contract, to perform any of the terms and conditions contained in any of the
Assigned Leases, any Other Lease or any Contract or otherwise to impose any
obligation upon the Lenders with respect to any of the Assigned Leases, any
Other Lease or any Contract or (ii) place upon the Participation Agent or the
Lenders (or their designee) any responsibility for the operation, control, care,
management or repair of any Property or any part thereof. Subject at all times
to the terms and conditions of this Assignment, the Assignor will at all times
promptly and faithfully perform in all respects, or cause to be performed in all
respects, all of its covenants, conditions and agreements contained in the
Assigned Leases, any Other Leases or any Contract now or hereafter existing on
the part of the Assignor to be kept and performed.

         7.       Amendments; Lessee's Consent. The Assignor will not enter into
any agreement subordinating, amending, extending or terminating any of the
Assigned Leases except as provided in Section 15.5 of the Participation
Agreement, and any such attempted subordination, amendment, modification,
extension or termination without compliance with such Section 15.5 shall be
void. If any of the Assigned Leases, any Other Lease or any Contract shall be
amended, it shall continue to be subject to the provisions hereof without the
necessity of any further act by any of the parties hereto. The Assignor, the
Participation Agent and the Lenders hereby consent to the provisions of Lessee's
Consent attached to this Assignment and agree to be bound thereby. Nothing in
this Section shall be construed as limiting or otherwise affecting in any way
the Assignor's right to receive directly the Excepted Payments.

         8.       Termination of this Assignment. This Assignment shall continue
in full force and effect until all obligations, liabilities and indebtedness of
any kind now or hereafter due to the Participants from the Assignor or the
Lessee under or with respect to the Loan Agreement or any of the other Operative
Documents, or which are otherwise secured hereby, whether now existing or
hereafter arising or incurred, have been fully paid, performed and satisfied,
and all Tranche A Loan Commitments and Tranche B Loan Commitments have
terminated, at which time this Assignment will terminate.

         9.       Ongoing Right to Collect Rents; Receivers. If notwithstanding
the terms of this Assignment, a petition or order for sequestration of rents, or
the appointment of a 


                                      -7-
   155
receiver or some similar judicial action or order is deemed required under
applicable state law to allow the Participation Agent or the Lenders to continue
to collect the moneys described in paragraphs 2(a), (b), (c) and (d) of this
Assignment, then it is agreed by the Assignor that any proof of claim or similar
document filed by the Lenders in connection with the breach or rejection of any
Lease by the lessee thereunder or the trustee of any lessee under any federal or
state insolvency statute shall for the purpose of perfecting the Participation
Agent's and the Lenders' rights conferred in said paragraph 2(d) be deemed to
constitute action required under such state law. Upon the occurrence and during
the continuance of a Loan Agreement Event of Default (not existing solely by
virtue of a Lease Event of Default), the Assignor hereby consents to the
appointment of a receiver for any or all of the Properties as a matter of right
and without any requirement for notice to the Assignor and without regard to the
solvency of the Assignor or to the collateral that may be available for the
satisfaction of the Notes and all other obligations under the Loan Agreement and
the other Operative Documents.

         10.      Amendment. This Assignment may not be amended or otherwise
modified except by a writing signed by the Assignor, the Participation Agent,
the Lenders and, if required by Section 15.5 of the Participation Agreement, the
Lessee, in accordance with the terms of the Participation Agreement.

         11.      Notices. All notices, demands, requests, consents, approvals
and other instruments under this Assignment shall be made in accordance with the
notice provisions of the Participation Agreement.

         12.      Successors and Assigns. All covenants, agreements,
representations and warranties in this Assignment by the Assignor and the
Lenders shall bind, and shall inure to the benefit of and be enforceable by,
their respective successors and assigns, whether or not so expressed.

         13.      Severability. If any provision or provisions, or if any
portion of any provision or provisions, in this Assignment is found by a court
of law of competent jurisdiction to be in violation of any local, state or
Federal ordinance, statute, law, administrative or judicial decision, or public
policy, and if such court should declare such portion, provision or provisions
to be illegal, invalid, unlawful, void or unenforceable as written, then it is
the intent of the parties hereto that such portion, provision or provisions
shall be given force to the fullest possible extent that they are legal, valid
and enforceable, that the remainder of this Assignment shall be construed as if
such illegal, invalid, unlawful, void or unenforceable portion, provision or
provisions were not contained therein, and that the rights, obligations and
interests of the Assignor, the Lenders and the Lessee under the remainder of
this Assignment shall continue in full force and effect.

REGARD TO CONFLICTS OF LAWS PRINCIPLES.

         15.      Counterparts. This Assignment may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same instrument.

                              Guarantee Provisions

         II.1 Guarantee. The Guarantor hereby absolutely, unconditionally and
irrevocably

         (a) guarantees the full and punctual payment and performance when due
(after giving effect to any applicable grace period), whether at stated
maturity, by required prepayment, declaration, acceleration, demand or
otherwise, of all Guarantee Obligations, whether for principal, interest, fees,
expenses or otherwise (including all such amounts which would become due but for
the operation of the automatic stay under Section 362(a) of the United States
Bankruptcy Code, 11 U.S.C. Section 362(a)), and the operation of Sections 502(b)
and 506(b) of the United States Bankruptcy Code, 11 U.S.C. Section 502(b) and
Section 506(b), and

         (b) indemnifies and holds harmless Lessee for any and all costs and
expenses (including reasonable attorney's fees and


                                      -2-
   168
expenses) incurred by Lessee in enforcing any rights under this Guarantee.

This Guarantee constitutes a guaranty of payment and performance when due and
not of collection, and the Guarantor specifically agrees that it shall not be
necessary or required that Lessee exercise any right, assert any claim or demand
or enforce any remedy whatsoever against Lessor (or any other Person) before or
as a condition to the obligations of the Guarantor hereunder.

         II.2 Guarantee Absolute, etc. This Guarantee shall in all respects be a
continuing, absolute, unconditional and irrevocable guaranty of payment and
performance, and shall remain in full force and effect until all Guarantee
Obligations have been paid or performed in full, all obligations of the
Guarantor hereunder shall have been paid or performed in full and all
Commitments of the Lenders under the Loan Agreement and the other Operative
Documents shall have terminated. The Guarantor hereby waives any rights it may
have under Section 2819 of the California Civil Code. The liability of the
Guarantor under this Guarantee shall be absolute, unconditional and irrevocable
irrespective of:

         (a)  any lack of validity, legality or enforceability of the
Participation Agreement or any other Operative Document;

         (b)  the failure of Lessee

              (i)  to assert any claim or demand or to enforce any right or
         remedy against Lessor or any other Person (including any other
         guarantor) under the provisions of the Participation Agreement, any
         other Operative Document or otherwise, or

              (ii) to exercise any right or remedy against any other guarantor
         of, or collateral securing, any Guarantee Obligations;

         (c)  any change in the time, manner or place of payment of, or
performance of, or in any other term of, all or any of the Guarantee
Obligations, or any other extension, compromise or renewal of any Obligation;

         (d)  any reduction, limitation, impairment or termination of the
Guarantee Obligations for any reason, including any claim of waiver, release,
surrender, alteration or compromise, and shall not be subject to (and the
Guarantor hereby waives any right to or claim of) any defense or setoff,
counterclaim, recoupment or termination whatsoever by reason of the invalidity,
illegality, nongenuineness, irregularity, compromise, unenforceability of, or
any other event or occurrence affecting, the Guarantee Obligations;


                                      -3-
   169
         (e) any amendment to, rescission, waiver, or other modification of, or
any consent to departure from, any of the terms of the Participation Agreement
or any other Operative Document;

         (f) any limitation of any recourse against the Lessor pursuant to
Section 26.9 of the Master Lease or Section 15.10 of the Participation
Agreement;

         (g) any assignment or transfer of Lessor's interest under any of the
Operative Documents; and

         (h) any other circumstance which might otherwise constitute a defense
available to, or a legal or equitable discharge of, Lessor, any surety or any
guarantor.

         II.3 Reinstatement, etc. The Guarantor agrees that this Guarantee shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment or performance (in whole or in part) of any of the Guarantee
Obligations is rescinded or must otherwise be restored by Lessee, upon its
insolvency, bankruptcy or reorganization or otherwise, as though such payment or
performance had not been made.

         II.4 Rights and Remedies. Guarantor waives any and all rights under
Section 2845 of the California Civil Code and any right which Guarantor may
otherwise have to require Lessee to (a) proceed against Lessor; (b) proceed
against or exhaust any security held from Lessor; or (c) pursue any other remedy
in Lessee's power whatsoever. Lessee may, at its election, exercise any right or
remedy it may have against Lessor or any security now or hereafter held by or
for the benefit of Lessee including, without limitation, the right to foreclose
upon any such security by judicial or nonjudicial sale, without affecting or
impairing in any way the liability of Guarantor hereunder except to the extent
the Guarantee Obligations may thereby be paid, even though any rights which
Guarantor may have or otherwise might obtain by subrogation against others might
be diminished or destroyed. Guarantor acknowledges that any such exercise of a
right or remedy with respect to any collateral security for the Guarantee
Obligations may result in a loss, in part or whole, of Lessee's right to collect
from Lessor any deficiency that may remain after any such exercise of such a
right or remedy and that, where such a loss occurs, Guarantor will also suffer a
loss of any rights and remedies, arising in law or equity, which Guarantor may
have to collect any amount from Lessor; and Guarantor agrees to remain bound
notwithstanding any such loss. Only the net proceeds from any such foreclosure,
after deduction of all costs and expenses authorized to be deducted pursuant to
the documents under which such security is held or by law, shall be applied
against the Guarantee Obligations. Lessee may at its discretion purchase all or
any part of such security so sold or offered for sale for its own account and
may apply against the amount bid therefor


                                      -4-
   170
all or any part of the Guarantee Obligations for which such security is held;
and in such case, only that portion of the Guarantee Obligations so applied,
after deduction of all costs and expenses authorized to be deducted pursuant to
the documents under which such security is held or law, shall be applied against
the Guarantee Obligations. Guarantor waives any defense arising out of the
absence, impairment or loss of any right of reimbursement or subrogation or
other right or remedy of Guarantor against Lessor or any such security, whether
resulting from the election by Lessee to exercise any right or remedy it may
have against Lessor, any defect in, failure of, or loss or absence of priority
with respect to Lessee's interest in such security, or otherwise. In the event
that any foreclosure sale is deemed to be not commercially reasonable, Guarantor
waives any right that it may have to have any portion of the Guarantee
Obligations discharged except to the extent of the amount actually bid and
received by Lessee at any such sale. Lessee shall not be required to institute
or prosecute proceedings to recover any deficiency as a condition of payment
hereunder or enforcement hereof.

         II.5 Separate Obligation. The obligations hereunder are independent of
the obligations of Lessor, and a separate action or actions may be brought and
prosecuted against Guarantor whether action is brought against Lessor or whether
Lessor be joined in any such action or actions; Guarantor waives the benefit of
any statute of limitations affecting its liability hereunder or the enforcement
thereof, to the fullest extent permitted by law. Any part performance of the
Guarantee Obligations by Lessor or other circumstances, which operate to toll
any statute of limitations as to Lessor shall not operate to toll the statute of
limitations as to Guarantor. Guarantor hereby waives any rights it may have
under Sections 2809 and 2810 of the California Civil Code and reaffirms that, in
any event, the obligations of Guarantor are independent of those of Lessor.
Guarantor understands that Lessee would not enter into the transaction with
Lessor in the absence of the foregoing covenants by Guarantor and the other
covenants of Guarantor contained in this Guarantee.

         II.6 Waiver of Notices and Demands. Guarantor waives all presentments,
demands for performance, notices of nonperformance, protests, notices of
protest, notices of dishonor, notices of default, and notices of acceptance of
this Guarantee and of the existence, creation or incurring of new or additional
Guarantee Obligations. At the option of Lessee, Guarantor may be joined in any
action or proceeding commenced by Lessee against Lessor in connection with or
based upon the Guarantee Obligations or any security therefor and recovery may
be had against Guarantor in such action or proceeding, without any requirement
that Lessee first assert, prosecute or exhaust any remedy or claim against
Lessor. Without limiting the foregoing, Guarantor acknowledges that repeated and
successive demands may be made and payments or performance made hereunder in
response


                                      -5-
   171
to such demands as and when, from time to time, Lessor may default in
performance of the Guarantee Obligations. Notwithstanding any such performance
hereunder, this Guarantee shall remain in full force and effect and shall apply
to any and all subsequent defaults by Lessor in payment or performance of the
Guarantee Obligations.

         II.7 Waiver of Defenses. Guarantor waives any defense arising by reason
of any disability or other defense of Lessor or by reason of the cessation from
any cause whatsoever of the liability of Lessor. Guarantor waives any setoff,
defense or counterclaim which Lessor or Guarantor may have or claim to have
against Lessee. Guarantor shall have no right of subrogation, and waives any
right to enforce any remedy which Lessee now has or may hereafter have against
Lessor, and waives any and all rights under Sections 2848 and 2849 of the
California Civil Code and any other benefit or right to participate in any
security now or hereafter held by Lessee.

         II.8 Right of Subrogation. Guarantor agrees that until such time as all
Guarantee Obligations are paid or performed in full to Lessee it shall not
exercise any of the rights it may have against Lessor, any other guarantor,
maker or endorser, and shall not exercise any of its rights to any reimbursement
and indemnity therefrom.

         II.9 Successors, Transferees and Assigns; Transfers of Interests, etc.
This Guarantee shall:

         (a)  be binding upon the Guarantor and its successors, transferees and
assigns; and

         (b)  inure to the benefit of and be enforceable by Lessee.


                                      III

                            2 - COVENANTS OF TRUSTOR

         A.   Master Lease.

              2.1  Subordination to Master Lease. The lien of this Deed of Trust
is subordinate and subject to a certain Master Lease and Mortgage of March 27,
1996, as amended, modified or supplemented from time to time and as amended as
of even date herewith (as amended, modified or supplemented, and including all
Lease Supplements thereto, the "Master Lease") between Trustor, as lessor, and
LAM, as lessee.

              2.2  Enforcement. Trustor shall use reasonable efforts, in good
faith and with diligence to enforce the obligations of the lessee under the
Master Lease, including the


                                      -6-
   183
lessee's duty to maintain and repair the Property, to provide insurance, to
comply with Requirements of Law and to pay all taxes, utility costs and other
charges relating to the Property. Lessor shall perform in all material respects
its duties and obligations under the Master Lease. Trustor shall promptly notify
Beneficiary of any Event of Default by LAM under the Master Lease.

         B.   Insurance Proceeds.

              2.3 Assignment of Proceeds. Trustor hereby absolutely and
unconditionally assigns to Beneficiary all insurance proceeds which it may be
entitled to receive. All such proceeds shall be held and distributed pursuant to
the terms of the Participation Agreement and the other Operative Documents.

              2.4 Transfer of Policy. In the event of the foreclosure of this
Deed of Trust or other transfer of the title to the Property in extinguishment,
in whole or in part, of the indebtedness secured hereby, all right, title and
interest of Trustor in and to any insurance policy then in force shall pass to
the purchaser or grantee, subject to the terms of the Participation Agreement
and the other Operative Documents.

         C.   Payments.

              2.5 Loan Payments. Trustor shall pay the principal, interest and
other charges due under the Note and the Loan Agreement according to their
terms.

              2.6 Reimbursement. Trustor shall pay immediately, upon demand,
after expenditure, all sums expended or expenses incurred by Trustee and/or
Beneficiary in acting under any of the terms of this Deed of Trust, including
any fees and expenses (including reasonable attorneys' fees) incurred in
connection with any reconveyance of the Property or any portion thereof, or to
compel payment of the Note or any portion of the indebtedness evidenced thereby
or in connection with any default thereunder, including attorneys' fees incurred
in any bankruptcy or judicial or nonjudicial foreclosure proceeding, with
interest from date of expenditure at the Overdue Rate provided for in the Loan
Agreement and said sums shall be secured hereby.

              2.7 Beneficiary's Statement Fee. Trustor shall pay the amount
demanded by Beneficiary or its authorized servicing agent for any statement
regarding the obligations secured hereby; provided, however, that such amount
may not exceed the maximum amount allowed by law at the time request for the
statement is made.


                                      -7-
   184
         D.   Condemnation.

              2.8  Condemnation. If the Property, the Collateral or any part
thereof, is taken or damaged by reason of any public improvement or condemnation
proceeding, or in any other similar manner, all compensation, awards and other
payments or relief therefor shall be held and distributed in accordance with the
terms of the Participation Agreement and the other Operative Documents. Trustor
hereby absolutely and unconditionally assigns to Beneficiary all such
compensation, awards, damages, rights of action and proceeds to which Trustor
shall be entitled (the "Proceeds"). Trustor agrees to execute such further
assignments of the Proceeds as Beneficiary or Trustee may require, consistent
with the terms of this Deed of Trust, the Participation Agreement and the other
Operative Documents.

         E.   Rents and Leases.

              2.9  Lease Covenants. "Lease" means any lease of all or any
portion of the Property or Improvements entered into at any time, including the
Master Lease, and includes any extensions or renewals thereof and any amendments
thereto. Beneficiary shall have the right, but not the obligation, to cure any
default of Trustor under any of the Leases and all amounts disbursed in
connection with said cure shall be deemed to be disbursements under the Loan
Agreement.

              2.10 Subordination of Leases and Attornment. Each Lease other than
the Master Lease of any portion of the Property or Improvements shall be
absolutely subordinate to the lien of this Deed of Trust, but shall contain a
provision satisfactory to Beneficiary, and in any event, each tenant thereunder,
by virtue of executing a Lease covering the Property, the Improvements or any
portion thereof, hereby agrees, that in the event of the exercise of the private
power of sale or a judicial foreclosure hereunder, such Lease, at the option of
the purchaser at such sale, shall not be terminated and the tenant thereunder
shall attorn to such purchaser and, if requested to do so, shall enter into a
new Lease for the balance of the term of such Lease then remaining upon the same
terms and conditions. Each such Lease shall, at the request of Beneficiary, be
separately assigned to Beneficiary upon Beneficiary's approved form, and each
such assignment shall be recorded and acknowledged by the tenant thereunder.
However, any such Lease and the rents thereunder shall be subject to this Deed
of Trust, regardless of whether Beneficiary requests a separate assignment.
Concurrently with the execution of any and all such Leases executed after the
date hereof, Trustor shall cause the tenants thereunder to execute an attornment
agreement in favor of Beneficiary in form and substance satisfactory to
Beneficiary and immediately thereafter deliver such agreement to Beneficiary.


                                      -8-
   185
         F.   Other Rights and Obligations.

              2.11 Assignment of Contracts. In addition to any other grant,
transfer or assignment effectuated hereby, without in any manner limiting the
generality of the grants in Article 1 hereof, Trustor shall assign to
Beneficiary, as security for the indebtedness secured hereby, Trustor's interest
in all agreements, contracts, licenses and permits affecting the Property and/or
the Collateral in any manner whatsoever, such assignments to be made, if so
requested by Beneficiary, by instruments in form satisfactory to Beneficiary;
but no such assignment shall be construed as a consent by Beneficiary to any
agreement, contract, license or permit so assigned, or to impose upon
Beneficiary any obligations with respect thereto.

              2.12 Preservation of Lien. Trustor shall do any and all acts
which, from the character or use of the Property or the Collateral, may be
reasonably necessary to protect and preserve the lien, the priority of the lien
and the security of Beneficiary granted herein, the specific enumerations herein
not excluding the general.

              2.13 Attorneys' Fees. Upon election of either Beneficiary or
Trustee so to do, employment of an attorney is authorized, and payment by
Trustor of all attorneys' fees, costs and expenses in connection with any action
or actions (including the cost of evidence or search of title) which may be
brought for the foreclosure of this Deed of Trust, for possession of the
Property covered hereby, for the appointment of a receiver, and/or for the
enforcement of any covenant or right in this Deed of Trust contained as
hereinafter provided, shall be secured hereby.

              2.14 Restrictions upon Transfer. Except as expressly permitted in
the Participation Agreement and other Operative Documents, in the event that the
interest of Trustor in the Property or the Collateral, or any part thereof, or
any interest therein, is sold, agreed to be sold, conveyed, encumbered,
alienated or otherwise transferred by Trustor, whether by operation of law or
otherwise, the Note, irrespective of the maturity dates expressed therein, at
the option of Beneficiary, and without demand or notice, shall immediately
become due and payable. In the event that Beneficiary does not elect to declare
the Note immediately due and payable, then, unless indicated otherwise in
writing by Beneficiary, Trustor shall nevertheless remain primarily liable for
the obligations hereunder and under the Note and any other instrument securing
the Note. Subject to the terms of the Participation Agreement and the other
Operative Documents, this provision shall apply to each and every sale,
transfer, encumbrance or conveyance, regardless whether or not Beneficiary has
consented to, or waived, Beneficiary's rights hereunder, whether by action or
non-action, in connection with any previous sale, transfer or conveyance. 2.14


                                      -9-
   186
              2.15 Further Assurances. Trustor agrees to execute, acknowledge
and deliver such documents and take such action as Beneficiary shall determine
to be necessary or desirable to further evidence, perfect or continue the
perfection and/or the priority of the lien and security interest granted by
Trustor herein.

              2.16 Protection of Security. Upon the occurrence of an Event of
Default hereunder, and subject to the terms of the Participation Agreement and
the other Operative Documents, Beneficiary, or Trustee upon written instructions
from Beneficiary (the legality thereof to be determined solely by Beneficiary),
may, without further notice to or demand upon Trustor, without releasing Trustor
from any obligation hereunder and without waiving its right to declare a default
as herein provided or impairing any declaration of default or election to cause
the Property to be sold or any sale proceeding predicated thereon:

                   (a) Take action in such manner and to such extent as either
may deem necessary to protect the security hereof, Beneficiary and Trustee being
authorized to enter upon and take possession of the Property for such purposes;

                   (b) Commence, appear in and/or defend any action or
proceedings purporting to affect the security hereof, and/or any additional or
other security therefor, the interests, rights, powers and/or duties of Trustee
and/or Beneficiary hereunder, whether brought by or against Trustor, Trustee or
Beneficiary;

                   (c) Pay, purchase, contest or compromise any claim, debt,
lien, charge or encumbrance which in the judgment of either may affect or appear
to affect the security and/or priority of this Deed of Trust, the interest of
Beneficiary or the rights, powers and/or duties of Trustee and/or Beneficiary
hereunder; and

                   (d) Beneficiary is authorized, either by itself or by its
agents to be appointed by it for that purpose or by a receiver appointed by a
court of competent jurisdiction, to enter into and upon and take and hold
possession of any portion or all of the Property and/or the Collateral, both
real and personal, and exclude Trustor and all other persons therefrom; and to
operate and manage the Property and/or the Collateral and rent and lease the
same, perform such reasonable acts of repair or protection as may be reasonably
necessary or proper to conserve the value thereof, and collect any and all
income, rents, issues, profits and proceeds therefrom, the same being hereby
assigned and transferred to Beneficiary for the benefit and protection of
Beneficiary, subject to the terms of the Participation Agreement and the other
Operative Documents. The collection and/or receipt of income, rents, issues,
profits


                                      -10-
   187
and/or proceeds by Beneficiary, its agent or receiver, after declaration of
default and election to cause the Property to be sold under and pursuant to the
terms of this Deed of Trust, the Participation Agreement and the other Operative
Documents shall not affect or impair such default or declaration of default or
election to cause the Property to be sold or any sale proceedings predicated
thereon, but such proceedings may be conducted and sale effected notwithstanding
the receipt and/or collection of any such income, rents, issues, profits and/or
proceeds. Any such income, rents, issues, profits and/or proceeds in the
possession of Beneficiary, its agent or receiver, at the time of sale and not
theretofore applied as herein provided, shall be held and distributed pursuant
to the terms of the Participation Agreement and the other Operative Documents.

Neither Trustee nor Beneficiary shall be under any obligation to make any of the
payments or do any of the acts referred to in this Section and any of the
actions referred to in this Section may be taken by Beneficiary irrespective of
whether any notice of default or election to sell has been given hereunder and
without regard to the adequacy of the security for the indebtedness secured
hereby.


                                      -11-
   188
                       3 - ASSIGNMENT OF LEASES AND RENTS


                                      -12-
   189
              Trustor hereby absolutely and unconditionally assigns and
transfers to Beneficiary (and has not heretofore otherwise so assigned or
transferred to any other person or entity) the Master Lease, together with all
other Leases (including all security deposits, guarantees and other security at
any time given as security for the performance of the obligations of the tenants
thereunder), income, rents, revenues, issues, deposits, profits and proceeds of
the Property and the Collateral to which Trustor may be entitled, whether now
due, past due or to become due, and hereby gives to and confers upon Beneficiary
the right, power and authority to collect such income, rents, revenues, issues,
deposits, profits and proceeds, subject to the terms of the Participation
Agreement and the other Operative Documents. This assignment of the Leases,
income, rents, revenues, issues, deposits, profits and proceeds constitutes an
irrevocable direction and authorization of all tenants under the Leases to pay
all rent, revenues, income and profits to Beneficiary upon demand and without
further consent or other action by Trustor. This is an absolute assignment, not
an assignment for security only, and Beneficiary's right to rents, revenues,
issues and profits is not contingent on Beneficiary's possession of all or any
portion of the Property. Trustor irrevocably appoints Beneficiary its true and
lawful attorney, at the option of Beneficiary at any time, to demand, receive
and enforce payment, to give receipts, releases and satisfactions, and to sue,
either in the name of Trustor or in the name of Beneficiary, for all such
income, rents, revenues, issues, deposits, profits and proceeds and apply the
same to the indebtedness secured hereby. It is understood and agreed that
neither the foregoing assignment of Leases, income, rents, revenues, issues,
deposits, profits and proceeds to Beneficiary nor the exercise by Beneficiary of
any of its rights or remedies under this Section or under Section 2.16 hereof
shall be deemed to make Beneficiary a "mortgagee-in-possession" or otherwise
obligated, responsible or liable in any manner with respect to the Property or
the Collateral or the use, occupancy, enjoyment or operation of all or any
portion thereof. Notwithstanding anything to the contrary contained herein or in
the Note, so long as no event which is, or with notice or passage of time or
both would constitute, an Event of Default shall have occurred, Trustor shall
have a license to collect all income, rents, revenues, issues, profits and
proceeds from the Property as trustee for the benefit of Beneficiary and
Trustor, and Trustor shall apply the funds so collected in accordance with the
terms of the Participation Agreement and the other Operative Documents. Upon the
occurrence of such event, such license shall be deemed revoked, and any rents
received thereafter by Trustor shall be delivered in kind to Beneficiary.
Trustor hereby irrevocably constitutes and appoints Beneficiary its true and
lawful attorney-in-fact to enforce, in Trustor's name or in Beneficiary's name
or otherwise, all rights of Trustor in the instruments, including checks and
money orders, tendered as payments of rents and to do any and all things
necessary and proper to carry out the purposes hereof.


                                      -13-
   190
              The security interest granted by this Article 3 above is intended
by Trustor to be subordinate to the provisions of a certain Assignment of Leases
and Rents of even date herewith executed by Trustor in favor of Beneficiary and
the Lenders (the "Assignment of Leases and Rents") and shall not take priority
unless and until the absolute assignment granted to Beneficiary by Trustor in
the Assignment of Leases and Rents is for any reason deemed to be ineffective.

                           4 - DEFAULTS AND REMEDIES

         A.   Defaults.

              4.1 Event of Default. Any Loan Agreement Event of Default shall
constitute an Event of Default ("Event of Default") hereunder.


                                      -14-
   191
         B.   Remedies.

              4.2 Acceleration and Foreclosure. Upon the occurrence of an Event
of Default hereunder, then and in each such event, Beneficiary may declare all
sums secured hereby immediately due and payable either by commencing an action
to foreclose this Deed of Trust as a mortgage, or by the delivery to Trustee of
a written declaration of default and demand for sale and of written notice of
default and of election to cause the Property to be sold, which notice Trustee
shall cause to be duly filed for record in case of foreclosure by exercise of
the power of sale herein. Should Beneficiary elect to foreclose by exercise of
the power of sale herein, Beneficiary shall also deposit with Trustee this Deed
of Trust, the Notes and such receipts and evidence of expenditures made and
secured hereby as Trustee may require, and notice of sale having been given as
then required by law and after lapse of such time as may then be required by law
after recordation of such notice of default, Trustee, without demand on Trustor,
shall sell the Property at the time and place of sale fixed by Beneficiary in
said notice of sale, either as a whole or in separate parcels, and in such order
as Beneficiary may determine, at public auction to the highest bidder for cash
in lawful money of the United States, payable at time of sale. Neither Trustor
nor any other person or entity other than Beneficiary shall have the right to
direct the order in which the Property is sold. Trustee may postpone sale of all
or any portion of the Property by public announcement at such time and place of
sale, and from time to time thereafter may postpone such sale by public
announcement at the time fixed by the preceding postponement. Trustee shall
deliver to such purchaser its deed or deeds conveying the Property, or any
portion thereof, so sold, but without any covenant or warranty, express or
implied. The recitals in such deed or deeds of any matters or facts shall be
conclusive proof of the truthfulness thereof. Any person, including Trustor,
Trustee or Beneficiary, may purchase at such sale.

              4.3 Rescission of Notice. Beneficiary, from time to time before
Trustee's sale, may rescind any such notice of breach or default and of election
to cause the Property to be sold by executing and delivering to Trustee a
written notice of such rescission, which notice, when recorded, shall also
constitute a cancellation of any prior declaration of default and demand for
sale. The exercise by Beneficiary of such right of rescission shall not
constitute a waiver of any breach or default then existing or subsequently
occurring, or impair the right of Beneficiary to execute and deliver to Trustee,
as above provided, other declarations of default and demand for sale, and
notices of breach or default, and of election to cause the Property to be sold
to satisfy the obligations hereof, nor otherwise affect any provision,
agreement, covenant or condition of the Notes, the Loan Agreement, the
Participation Agreement, any of the other Operative Documents and/or of this
Deed of


                                      -15-
   192
Trust or any of the rights, obligations or remedies of the parties hereunder.

              4.4 Proceeds of Sale. After deducting all costs, fees and expenses
of Trustee and of this trust, including the cost of appraisal and evidence of
title in connection with sale and attorneys' fees, Trustee shall apply the
proceeds of sale in accordance with the terms of the Participation Agreement and
the other Operative Documents.

              4.5 Other Security. If Beneficiary at any time holds additional
security for any obligations secured hereby, it may enforce the terms hereof or
otherwise realize upon the same, at its option, either before or concurrently
herewith or after a sale is made hereunder, and may apply the proceeds upon the
indebtedness secured hereby without affecting the status of or waiving any right
to exhaust all or any other security, including the security hereunder, and
without waiving any breach or default or any right or power whether exercised
hereunder or contained herein or in any such other security. Trustor, for itself
and for all persons hereafter claiming through or under it or who may at any
time hereafter become holders of liens junior to the lien of this Deed of Trust,
hereby expressly waives and releases all rights to direct the order in which any
of the Property or any other property which is security for the indebtedness
secured hereby shall be sold and to have any of the Property, or any other
property which is security for the indebtedness secured hereby, marshalled upon
any foreclosure of this Deed of Trust or of any other security for any
indebtedness secured hereby.

              4.6 Remedies Cumulative. No remedy herein conferred upon or
reserved to Trustee or Beneficiary is intended to be exclusive of any other
remedy herein or by law provided or permitted, but each shall be cumulative and
shall be in addition to every other remedy given hereunder or now or hereafter
existing at law or in equity or by statute. Every power or remedy given by this
instrument to Trustee or Beneficiary or to which either of them may be otherwise
entitled may be exercised concurrently or independently, from time to time and
as often as may be deemed expedient by Trustee or Beneficiary, and either of
them may pursue inconsistent remedies. No delay or omission of Trustee or
Beneficiary to exercise any right or power accruing upon any Event of Default
shall impair any right or power or shall be construed to be a waiver of any
Event of Default or any acquiescence therein; and every power and remedy may be
exercised from time to time as often as may be deemed expedient by Trustee or
Beneficiary.

              4.7 Appointment of Receiver. Upon the occurrence of an Event of
Default hereunder, Beneficiary, as a matter of right and without further notice
to Trustor or anyone claiming under it, and without regard to the then value of
the Property or the interest of Trustor therein, shall have the right to apply
to


                                      -16-
   193
any court having jurisdiction to appoint a receiver or receivers of the Property
or any portion thereof, and Trustor hereby irrevocably consents to such
appointment and waives notice of any application therefor. Any such receiver or
receivers shall have all the usual powers and duties of receivers in like or
similar cases and all the powers and duties of Beneficiary in case of entry as
provided herein and shall continue as such and exercise all such powers until
the date of confirmation of sale of the Property unless such receivership is
sooner terminated.

              4.8 Other Remedies. Upon the occurrence of any Event of Default,
Beneficiary shall be entitled to exercise all other remedies provided to
Beneficiary under any of the Loan Documents or otherwise available under
California law or set forth herein, including (a) the institution of a suit in
equity or other appropriate proceedings for specific performance or an
injunction against a violation of this Deed of Trust; and/or (b) termination of
all commitments to cause the reconveyance of the Property, and all other
obligations of Beneficiary and all rights of Trustor under the Loan Documents,

all statutes of limitation as a defense to any demand secured by this Deed of
Trust is hereby waived to the full extent permitted by law.

permitted by law: (a) the benefit of all laws now existing or that may hereafter
be enacted providing for any appraisement before sale of any portion of the
