Alternate Base Rate, where notice shall be on the same Business Day)
pursuant, in each case, to a Funding Request substantially in the form of
Exhibit B (a "FUNDING REQUEST"), specifying (i) the proposed Funding Date,
(ii) the amount and purpose of the Advance requested and the amount of the
Tranche T Participant's Tranche A Participation Interest therein, (iii) the
initial Interest Period for such Advance (on a Tranche by Tranche basis),
(iv) the payees of such Advance, (v) that the Advance will be used to fund
Property Acquisition Costs or Property Improvement Costs, (vi) the allocation
of such Advance to the respective Property Acquisition Costs and Property

Participants shall likewise be deemed to be so allocated in accordance with
their respective Commitment

                                        3




Percentages applicable to each Type of Advance requested), and (vii) that, in
the case of an Expansion Improvements Advance, to the knowledge of the
Construction Agent, no Construction Termination Event has occurred and is
continuing as of the date of such Funding Request. The Agent shall promptly
provide notice of such Funding Request to each Participant. The Construction
Agent shall not request more than one Funding Date during any calendar month.
Each Advance (other than an Interest Payment Advance or an amount capitalized
pursuant to SECTION 3.7(e)) shall be in a minimum amount of $500,000. Subject
to the satisfaction or waiver of the conditions precedent to such Advance set
forth in SECTION 6, each Participant, other than the Lessor, shall fund its
pro rata share of such Advance by making available to the Lessor its
proportionate share of such Advance in immediately available federal funds by
wire transfer to the Agent for deposit to the Lessor's demand deposit account
with the Agent not later than 12:00 noon, Chicago time, on the applicable
Funding Date. Upon (i) the Lessor's receipt of the funds provided by the
Participants with respect to an Advance, and (ii) satisfaction or waiver of
the conditions precedent to such Advance set forth in SECTION 6, the Lessor
shall (A) in the case of an Advance for the acquisition of the Existing
Facility, pay the Property Acquisition Costs to the Existing Owner, and (B)
in the case of other Advances, pay Property Improvement Costs to the payees
specified in the applicable Funding Request, or deliver to the Construction
Agent funds that the Construction Agent reasonably believes will be due, in
the sixty (60) days following such Advance, from the Construction Agent to
third parties in respect of Property Improvements Costs, or as payment or
reimbursement of Property Improvements Costs previously paid by the
Construction Agent, in each case from the funds provided by the Participants
for such Advance.

allocation for each Participant of (i) the amount of its Commitment
representing its Tranche A Participation Interest ("TRANCHE A PARTICIPATION
INTEREST COMMITMENT"), including its Tranche A Existing Facility

Lessor, the Agent and the Participants have approved all such allocations and
percentages. SCHEDULE I shall be amended (including adding Tranche A
Expansion Improvements Participation Interest Commitments, Tranche B
Expansion Improvements Participation Interest Commitments, and Tranche C
Equity Interest Expansion Improvements Commitments in effect prior to and
after the Completion Date with respect to Expansion Improvements) as required
to reflect any increase in the Total Commitment in accordance with SECTION

addition of additional Participants pursuant to SECTION 12.1.

                                        4




     SECTION 3.6 TERMINATION, REDUCTION, EXTENSION OR INCREASE OF
PARTICIPANTS' COMMITMENT. (a) The Lessor shall have the right, upon not less
than five Business Days' written notice to the Agent, to terminate the
Participants' Commitments or, from time to time, to reduce the amount of the
Participants' Commitments, PROVIDED that (i) after giving effect to such
reduction, the aggregate outstanding principal amount of the Tranche A
Participation Interests shall not exceed the aggregate Tranche A
Participation Interest Commitments, (ii) after giving effect to such
reduction, the aggregate outstanding principal amount of the Tranche B
Participation Interests shall not exceed the aggregate Tranche B
Participation Interest Commitments, (iii) after giving affect to such
reduction, the aggregate outstanding principal balance of the Tranche C
Equity Interests shall not exceed the aggregate Tranche C Equity Interest
Commitments, and (iv) any such reduction shall be made pro rata among the
Participants' Commitments within each Tranche. Prior to the occurrence and
continuance of an Event of Default, the Lessor shall exercise such right only
as directed by the Lessee and after the occurrence and during the continuance
of an Event of Default the Lessor shall exercise such right only as directed
by the Required Participants.

     (b) The Lessee may, by written request to the Lessor and Agent (which
the Agent shall promptly forward to each Participant, together with the
related Renewal Request received by the Agent pursuant to Section 21.1 of the
Lease) given not later than 180 days prior to the Maturity Date then in
effect, request (each, an "EXTENSION REQUEST") that such Maturity Date be
extended to the date that is two (2) years after the Maturity Date then in
effect. No later than the date (the "EXTENSION RESPONSE DATE") which is 90
days after any such request has been delivered to each of the Participants,
each Participant will notify the Lessor in writing (with a copy to the Agent
and the Lessee) whether or not it consents to such Extension Request (which
consent may be granted or denied by each Participant in its sole discretion
and may be conditioned on receipt of such financial information or other
documentation as may be specified by such Participant including without
limitation satisfactory appraisals of the Property), PROVIDED that (i) any
Participant that fails to so advise the Lessor on or prior to the applicable
Extension Response Date shall be deemed to have denied such Extension
Request, and (ii) notwithstanding anything contained herein to the contrary,
the Tranche T Participant shall be deemed to have consented to any such
Extension Request. The extension of the then-current Maturity Date
contemplated by an Extension Request shall become effective as of the
Maturity Date then in effect (the "EXTENSION EFFECTIVE DATE") on or after the
Extension Response Date on which all of the Participants (other than
Non-Consenting Participants which have been replaced by Replacement
Participants in accordance with SECTION 3.6(c)) shall have consented to such
Extension Request; PROVIDED that:

                           (A)      on both the date of the applicable
                           Extension Request and the applicable Extension
                           Effective Date, (x) each of the representations
                           and warranties made by the Lessee, the Guarantor
                           and the Lessor in or pursuant to the Operative
                           Documents shall be true and correct in all
                           material respects as if made on and as of each
                           such date, except for representations and
                           warranties made as of a specific date, which
                           shall be true and correct in all material
                           respects as of such date, (y) no Default or Event
                           of Default shall have occurred and be continuing,
                           and (z) on each of such dates the Agent shall
                           have received a certificate of the Lessee, the
                           Guarantor and the Lessor, each as to itself, as
                           to the matters set forth in

                                        5



                           CLAUSE (x) above and from the Lessee and
                           the Guarantor as to the matters set forth in
                           CLAUSE (y) above, and

                           (B)    the Agent and the Required Participants
                           shall have received satisfactory evidence that the
                           Expiration Date shall, after giving effect to any
                           extension thereof which has become effective on or
                           prior to such Extension Effective Date, occur on
                           the Maturity Date then in effect as so extended,
                           and

                           (C)   in no event shall more than two (2) two-year
                           extensions of the Initial Maturity Date be requested
                           pursuant to this SECTION 3.6(b).

     (c) The Lessor (after consultation with, and at the direction of, the
Lessee) shall be permitted to replace any Non-Consenting Participant (or any
Participant which has not consented to an increase in the Total Commitment
requested pursuant to SECTION 3.6(d) (an "OTHER NON-CONSENTING PARTICIPANT")
with one or more replacement banks or other financial institutions acceptable
to the Agent (a "REPLACEMENT PARTICIPANT") at any time on or prior to the
date which is 90 days after the Extension Response Date (or the date an Other
Non-Consenting Participant delivered its Commitment Increase Response, as the
case may be); PROVIDED that (i) such replacement does not conflict with any
Requirement of Law, (ii) the Replacement Participant shall purchase, at par,
all of the Participation Interest of such Non-Consenting Participant (or
Other Non-Consenting Participant, as applicable), on or prior to the date of
replacement, (iii) the Lessee shall be liable to such Non-Consenting
Participant (or Other Non-Consenting Participant, as applicable) under
SECTION 13.6 of this Agreement if any Advance (or any Participation Interest
therein) shall be prepaid (or purchased) other than on the last day of the
Interest Period or Interest Periods relating thereto, (iv) the Replacement
Participant, if not already a Participant, shall be reasonably satisfactory
to the Agent, (v) such replacement shall be made in accordance with the
provisions of SECTION 12 of this Agreement (PROVIDED that the Lessee shall be
obligated to pay the Transaction Expenses arising in connection therewith),
and (vi) the Replacement Participant shall have agreed to be subject to all
of the terms and conditions of this Agreement (including the extension of the
Maturity Date contemplated by the Extension Request or increase in the Total
Commitment contemplated by the Commitment Increase Request, as the case may
be) and the other Operative Documents. The Agent hereby agrees to cooperate
with the Lessee and the Lessor in their efforts to arrange one or more
Replacement Participants as contemplated by this SECTION 3.6(c).

     (d) Lessee acknowledges that the amount of the Total Commitment as of
the Closing Date is an amount sufficient to fund only the Property
Acquisition Costs, Property Improvement Costs related to Tenant Improvements
not to exceed the amount of the Tenant Improvements Sublimit, and related
broker commissions and Transaction Expenses. Lessee acknowledges that as of
the Closing Date no Participant has committed, sought or obtained internal
investment or credit approval to fund any Property Improvement Costs related
to Expansion Improvements, and no Participant is under any obligation to do
so. In connection with the delivery of the Plans and Specifications, Budget
and Appraisal pursuant to Section 6.2 hereof the Lessee may request (the
"COMMITMENT INCREASE REQUEST") in writing to the Lessor and the Agent that
the Participants (other than the Tranche T Participant) agree to increase the
Total Commitment to an amount to be agreed upon by the parties hereto. The
amount of the increase to the Total Commitment

                                        6




pursuant to this Section shall be referred to herein as the "INCREMENTAL
COMMITMENTS", and, subject to satisfaction of the conditions set forth in
SECTIONS 6.2 and 6.3 hereof, shall be used to fund Property Improvement Costs
related to Expansion Improvements. Within thirty (30) days following the
delivery of such Commitment Increase Request, each Participant (other than
the Tranche T Participant) shall deliver to the Agent and the Lessee written
notice (each, a "COMMITMENT INCREASE RESPONSE") stating (i) whether or not
such Participant consents to the increase in the Total Commitment requested
in the Commitment Increase Request, and (ii) the amount, if any, of the
Incremental Commitments such Participant is willing to purchase. The failure
of a Participant to respond in writing within such time period shall
constitute a denial of the requested commitment increase by such Participant.
The increase in the Total Commitment requested shall be subject to the prior
written consent of the Lessor, the Agent and each Participant (which consent
may be granted or denied by each such Participant in its sole discretion and
may be conditioned upon receipt of such financial information, appraisals,
documents or other information or materials as may be specified by such
Participant and shall further be subject to receipt by each such Participant
of such internal investment and credit approvals as may be required by it and
to such other terms and conditions as each such Participant may request),
PROVIDED that the Tranche T Participant shall be deemed to have consented to
any increase in the Total Commitments requested pursuant to a Commitment
Increase Request so long as the Commitment of the Tranche T Participant is
not increased in connection therewith. The effectiveness of any such increase
shall be subject to the further condition precedent that the Lessee, the
Lessee's General Partner, the Guarantor, the Lessor, the Agent and each
Participant shall have executed and delivered such amendments to the
Operative Documents as may be reasonably required and negotiated in good
faith in order to reflect such increase in, and any conditions to the
increase in the Total Commitment. The parties hereto each acknowledge and
agree that, in the event of any such increase in the Total Commitment, the
Incremental Commitments may be allocated among any or all of the existing
Participants (other than the Tranche T Participant) as of the date of such
increase and/or to a new Participant becoming a party hereto as of the date
of and in connection with such increase, all as determined by the Agent after
consultation with the Lessee; PROVIDED that (i) the Commitment of any
particular Participant shall not be increased pursuant to the foregoing by an
amount greater than the portion of the Incremental Commitments such
Participant was willing to purchase as set forth in the Commitment Increase
Response delivered by such Participant, (ii) neither the Lessee, the Tranche
T Participant nor any other Affiliate of the Lessee shall be permitted to
participate in any such Incremental Commitments during the Construction
Period in respect of the Expansion Improvements, and (iii) the parties hereto
currently anticipate that, subject to satisfaction of the terms and
conditions herein contained (x) ABN AMRO Bank N.V. or one of its affiliates
will provide the Incremental Commitments required to fund the Expansion
Improvements, and (y) the amount of the Incremental Commitments would be
$13,000,000.

     (e) On the Outside Completion Date with respect to the Tenant
Improvements, the Participants' Commitments (excluding any Incremental
Commitments then approved and outstanding) shall be reduced automatically
without any notice or other action by Lessor or any Participant hereunder, to
be equal to the then aggregate outstanding principal amount of the respective
Participant's Participation Interests with respect to the Commitments (other
than the Incremental Commitments) If the Expansion Improvements Closing Date
has occurred, then on the Outside Completion Date with respect to the
Expansion Improvements, the Participants' Incremental Commitments shall be
reduced automatically without any notice or other action by

                                        7




Lessor or any Participant hereunder, to be equal to the then aggregate
outstanding principal amount of the respective Participant's Participation
Interests with respect to such Incremental Commitments.

     SECTION 3.7 INTEREST RATES, YIELD AND PAYMENT DATES.

     (a) Each outstanding Advance (other than that portion of the Advance to
be made on the Closing Date to finance Tranche C Equity Interests, which
shall bear yield at a rate equal to the Alternate Base Rate unless and until
such portion of such Advance is converted to a Eurodollar Rate Advance in
accordance with this SECTION 3.7(a)) shall bear interest (in the case of the
Tranche A Participation Interests and Tranche B Participation Interests
therein) or yield (in the case of the Tranche C Equity Interest therein) for
each day during each Interest Period with respect thereto as follows:

         (i)      in the case of that portion of the Advances used to finance
         (1) during the Term, the Property Acquisition Costs and the Property
         Improvements Costs in respect of the Existing Facility and the
         Tenant Improvements and (2) after the Construction Period with
         respect to Expansion Improvements, the Property Improvements Costs
         of the Expansion Improvements:

                           (A) in respect of the Tranche A Participation
                           Interests and Tranche B Participation Interests
                           financing such Property Costs, a rate per annum
                           for such Interest Period equal to zero percent
                           PLUS the Applicable Margin; and

                           (B) in respect of the Tranche C Equity Interests
                           financing such Property Costs, a rate per annum for
                           such Interest Period equal to the Eurodollar Rate
                           determined two (2) Business Days prior to the first
                           day of such Interest Period PLUS the Applicable
                           Margin; and

         (ii)    during the Construction Period with respect to Expansion
         Improvements only, in the case of that portion of the Advances used
         to finance the Property Improvements Costs of the Expansion
         Improvements:

                           (A)   in respect of the Tranche A Participation
                           Interests and the Tranche B Participation
                           Interests financing such Property Costs, a rate
                           per annum equal to the sum of the Eurodollar Rate
                           with an Interest Period of one month determined
                           two (2) Business Days prior to the first day of
                           each such Interest Period PLUS the Applicable
                           Margin; and

                           (B)   in respect of the Tranche C Equity Interests
                           financing such Property Costs, a rate per annum for
                           such Interest Period equal to the Eurodollar Rate
                           determined two (2) Business Days prior to the first
                           day of such Interest Period PLUS the Applicable
                           Margin.

         The Lessee shall give irrevocable notice to the Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
Appendix 1, of the length of each Interest Period to be applicable to Tranche
C Equity Interests. In the case of the Advance made on the

                                        8




Closing Date, such notice (which may be set forth in the Funding Request
delivered on the Closing Date) shall further set forth the Lessee's election
to convert such Tranche C Equity Interests to a Eurodollar Rate, which
election shall become effective three Business Days following the date of
such notice. There shall not be more than four (4) Interest Periods
outstanding at any time.

     (b) If all or a portion of (i) the amount of any Advance, (ii) any
interest or yield 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 or yield
at a rate per annum which is equal to the Overdue Rate.

     (c) Subject to the next sentence of this PARAGRAPH (c), interest and
yield shall be payable in cash in arrears on each Scheduled Payment Date,
PROVIDED that (i) interest and yield accruing pursuant to PARAGRAPH (b) of
this SECTION 3.7 shall be payable from time to time on demand and (ii) each
prepayment of Advances shall be accompanied by accrued interest and yield to
the date of such prepayment on the amount of Advances so prepaid. During the
Construction Period with respect to the Expansion Improvements only, interest
and yield accruing on that portion of the Expansion Improvements Advances
shall be capitalized as provided in SECTION 3.7(d).

     (d) On each date which is three Business Days prior to any Scheduled
Payment Date prior to the Completion Date with respect to the Expansion
Improvements, the Construction Agent shall be deemed to have requested an
Advance comprised of an Interest Payment Advance pursuant to SECTION 3.4 and
the Lessor shall be deemed to have requested a purchase pursuant to SECTION
3.2 of Participation Interests in such Advance in an amount equal to the
aggregate amount of the interest or yield due and payable on such date with
respect to accrued interest and yield on that portion of the outstanding
Expansion Improvements Advances. The Funding Date with respect to any such
Interest Payment Advance and purchase of Participation Interests therein
shall be the relevant Scheduled Payment Date (PROVIDED that such Advance and
the purchase of such Participation Interests shall be subject to satisfaction
of the applicable conditions precedent set forth in SECTION 6) and the
proceeds of such payment shall be applied to pay such accrued interest and
yield.

     (e)      CAPITALIZATION OF CERTAIN AMOUNTS PRIOR TO COMPLETION DATE WITH
RESPECT TO EXPANSION IMPROVEMENTS.

         (i)      On each date prior to the Completion Date with respect
         to the Expansion Improvements that any amount is payable under
         the Operative Documents on account of (A) accrued interest and
         accrued yield on outstanding Expansion Improvement Advances (to
         be capitalized to the extent provided in SECTION 3.7(d)), (B)
         fees pursuant to SECTION 4 (other than SECTION 4.1(a)), (C)
         Transaction Expenses of the Lessor, the Agent or any Participant

         SECTION 3.7(e)) required by any provision of the Operative
         Documents to be capitalized prior to such Completion Date, such
         amounts shall be capitalized by automatically treating such amount
         as an Advance and a related purchase of Participation Interests
         therein made on such date.

                                        9



         (ii)     If any Lessor Party shall  request the Lessor to capitalize
         the amount of (A) any Claims pursuant to CLAUSE (5)(B) of the
         proviso to SECTION 13.1, or (B) any loss or liability pursuant
         to Section 24.1 of the Lease, and if the Lessor in its discretion
         consents to such capitalization, any such amount shall be
         capitalized by automatically treating such amount as an Advance and
         a related purchase of Participation Interests therein (funded by
         such Lessor Party); PROVIDED, HOWEVER, that the Lessee shall
         have no obligation to pay any such amounts if the  Lessee
         exercises the Remarketing Option or is otherwise required to
         pay the Expansion Improvements Residual Value Guarantee Amount in
         accordance with the Lease and the other Operative Documents except
         from the proceeds of the sale or disposition of the Property. If
         any such capitalized amounts are included in the Asset Termination
         Value, Lease Balance or Participant Balance (the "3.7(e)(ii)
         PORTION" of the Asset Termination Value, Lease Balance or
         Participant Balance), all the Lessee payments and other amounts
         applied to the Asset Termination Value, Lease Balance or
         Participant Balance shall be applied as provided in SECTIONS 3.11
         through 3.21 of this  Agreement.  The Agent shall notify the Lessee,
         the Lessor and each Participant of each amount capitalized and
         treated as an Advance (and a related purchase of Participation
         Interests therein) under this SECTION 3.7(e)(ii) within fifteen (15)
         days after each such Advance.

     (f) CASH COLLATERAL AGREEMENT. On each Funding Date the Lessee shall
deposit cash collateral pursuant to the Cash Collateral Agreement against the
Tranche B Participation Interests and the Tranche C Equity Interests and
shall maintain the Cash Collateral from time to time pursuant to and in
accordance with the terms of the Cash Collateral Agreement. If the Total
Commitment is increased pursuant to SECTION 3.6(d), the parties shall enter
into the Securities Collateral Agreement and in connection with fundings of
Expansion Improvements Advances, the Lessee shall deposit and maintain
additional cash or securities collateral as required thereby.

     SECTION 3.8 COMPUTATION OF INTEREST AND YIELD.

     (a) Whenever it is calculated on the basis of the Alternate Base Rate,
interest and yield shall be calculated on the basis of a 365- (or 366-, as
the case may be) day year for the actual days elapsed; otherwise, interest
and yield shall be calculated on the basis of a 360-day year for the actual
days elapsed. The Agent shall as soon as practicable notify the Lessor, the
Lessee and the Participants of each determination of a Eurodollar Rate. Any
change in the interest rate or yield rate on an Advance resulting from a
change in the Alternate Base Rate or the Eurocurrency Reserve Requirements
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, the Lessee and the Participants of the effective date and the amount
of each such change in interest rate or yield rate.

     (b) Each determination of an interest rate or a yield rate by the Agent
pursuant to any provision of this Agreement shall be conclusive and binding
on the Lessor, the Lessee and the Participants in the absence of manifest
error. The Agent shall, at the request of such parties, deliver to such

     SECTION 3.9 PRO RATA TREATMENT AND PAYMENTS.

     (a) Each participation in the Advances of a particular Type by the
Participants holding Commitments to fund such Type hereunder and each
reduction of the Commitments of the Participants shall be made pro rata among
the applicable Tranche A Participants, Tranche B Participants and Tranche C
Participants according to the respective applicable Commitment Percentages of
each such Participant then in effect. Except as otherwise provided in
SECTIONS 3.11 through 3.21, each payment (including each prepayment) by the
Lessor on account of Participation Interests representing the amount of
principal and interest or yield on the Advances shall be made pro rata among
the applicable Tranche A Participants, Tranche B Participants and Tranche C
Participants according to the respective Participation Interests of each such
Participant then in effect. Any payment required to be made to the
Participants in any particular Tranche and within any particular Type shall
be made pro rata among such Participants, without priority of any one such
Participant over any others within such Tranche or Type, in the proportion
that such Participant's Participant Balance within such Tranche and Type
bears to the aggregate Participant Balances of all Participants within such
Tranche and Type. All payments (including prepayments) to be made by the
Lessor hereunder to the Participants with respect to their Participation
Interests, whether on account of principal, interest, yield or otherwise,
shall be payable to the extent received by the Lessor from or on behalf of
the Lessee, shall be made without setoff or counterclaim and shall be made
prior to 2:00 p.m., Chicago time, on the due date thereof to the Agent, for
the account of the applicable Participants, at the Agent's office referred to
in SECTION 15.3 of this Agreement, in Dollars and in immediately available
funds. The Agent shall distribute such payments to the applicable
Participants promptly upon receipt in like funds as received; it being
understood that any such payment received by the Agent on a timely basis and
in accordance with the provisions of the Lease shall be distributed on the
date on which such funds are so received. If any payment hereunder (other
than payments of Participation Interests in the Advances) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment of Participation Interests
in an Advance becomes due and payable on a day other than a Business Day, the
maturity thereof shall be extended to the next succeeding Business Day unless
the result of such extension would be to extend such payment into another
calendar month, in which event such payment shall be made on the immediately
preceding Business Day. In the case of any extension or shortening of the due
date of any payment pursuant to the preceding two sentences, interest or
yield thereon shall be payable at the then applicable rate during such
extension or until such shortened due date, as the case may be.

     (b) Unless the Agent shall have been notified in writing by any
Participant prior to funding its Participation Interest in an Advance that
such Participant will not make its share of such Advance available to the
Agent, the Agent may assume that such Participant is making such amount
available to the Agent. If such Participant's share of such Advance is not
made available to the Agent by such Participant on or prior to such Funding
Date, the Lessor shall not be required to make such portion of such Advance
to the Lessee.

     SECTION 3.10 THE ACCOUNT. The Agent may if it so desires establish
an account (the "ACCOUNT") into which the Agent and the Lessor shall deposit
all payments, receipts and other consideration of any kind whatsoever paid
under the Lease and received by the Agent or the Lessor pursuant to this
Agreement, the Lease and any other Operative Document. Each of

Rent comprising interest or yield on the Advances (and any payment of

                    CERTAIN INTENTIONS OF THE PARTIES

     SECTION 5.1 NATURE OF TRANSACTION. (a) It is the intent of the
parties hereto that: (i) the Lease constitutes an "operating lease" pursuant
to Statement of Financial Accounting Standards No. 13, as amended and
interpreted, for purposes of Lessee's financial reporting, and (ii) for
purposes of federal, state and local income or franchise taxes (and for any
other tax imposed on or measured by income, and documentary, intangibles and
transfer taxes, the transaction contemplated hereby is a financing
arrangement and preserves ownership in the Property in the

                                        19




Lessee. The parties shall take no action inconsistent with such intention.
Nevertheless, the Lessee acknowledges and agrees that neither the Agent, the
Lessor nor any Participant (other than the Tranche T Participant) 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.

     (b) Specifically, without limiting the generality of SUBSECTION (a) of
this SECTION 5.1, the parties hereto intend and agree that with respect to
the nature of the transactions evidenced by the Lease in the context of the
exercise of remedies under the Operative Documents, in the case 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, any State or Commonwealth thereof or any foreign
country affecting the Lessee, the Lessor or any Participant or any
enforcement or collection actions arising out of or relating to bankruptcy or
insolvency laws, (i) the transactions evidenced by the Operative Documents
shall be deemed to be loans made by the Lessor and the Participants to the
Lessee secured by the Property, (ii) the obligations of the Lessee under the
Lease to pay Basic Rent, Supplemental Rent, Asset Termination Value or
Residual Value Guarantee Amount in connection with any purchase or sale of
the Property pursuant to the Lease shall be treated as payments of interest
on and principal of, respectively, loans from the Lessor and the Participants
to the Lessee, and (iii) the Lease grants a security interest and mortgage or
deed of trust lien, as the case may be, in the Property to the Lessor and
assigned by the Lessor to the Agent for the benefit of the Participants to
secure the Lessee's performance and payment of all amounts under the Lease
and the other Operative Documents.

     (c) If the transaction evidenced by this Agreement and the other
Operative Documents can no longer be treated as an operating lease pursuant
to GAAP for accounting purposes, all provisions in the Operative Documents
limiting the Lessee's obligation to pay the Asset Termination Value
(including the Remarketing Option) shall no longer apply. If any such change
in accounting treatment shall occur, the Lessee, the Guarantor, the Lessor,
the Construction Agent, the Lessee's General Partner, the Agent and the
Participants shall negotiate in good faith to enter into such amendments to
the Operative Documents as may be reasonably necessary or desirable to
reflect the foregoing.

     (d) In the event that, after the date hereof, the UCC as enacted and in
effect in any applicable jurisdiction shall be revised or amended or
amendments thereto shall become effective, the Lessee, the Guarantor, the
Lessor, the Agent and the Participants shall negotiate in good faith to enter
into such amendments to the Operative Documents as may be reasonably
necessary or desirable to effect the intended purposes of this Agreement and
the other Operative Documents in light of the effect of such revisions or
amendments.

     SECTION 5.2 AMOUNTS DUE UNDER LEASE. Anything else herein or
elsewhere to the contrary notwithstanding, it is the intention of the Lessee,
the Guarantor, the Lessee's General Partner, the Lessor, the Participants and
the Agent that: (i) the amount and timing of installments of Basic Rent due
and payable from time to time from the Lessee under the Lease shall be equal
to the aggregate payments due to the Participants in respect of their
Participation Interests on each Payment Date; (ii) if the Lessee elects the
Purchase Option or becomes obligated to

                                        20




purchase the Property under the Lease, the Participation Interests, all fees
and all of the interest on overdue amounts thereon and all other obligations
of the Lessee owing to the Lessor, the Participants and the Agent shall be
paid in full by the Lessee; (iii) if the Lessee properly elects the
Remarketing Option, the Lessee shall only be required to pay to the Lessor
the proceeds of the sale of the Property, the Residual Value Guarantee Amount
and any amounts due pursuant to SECTION 13 of this Participation Agreement
and Section 22.2 of the Lease (which aggregate amounts may be less than the
Asset Termination Value); and (iv) upon a Lease Event of Default resulting in
an acceleration of the Lessee's obligation to purchase the Property under the
Lease, the amounts then due and payable by the Lessee under the Lease shall
include all amounts necessary to pay in full the Asset Termination Value,
plus all other amounts then due from the Lessee to the Participants, the
Agent and the Lessor under the Operative Documents.

stockholders or any approval or consent of any Person under any indenture,
loan agreement, other agreement for borrowed money or other material
agreement or material contractual arrangement by which the Guarantor or any
of its property or assets may be subject, except for such approvals or
consents which will be obtained on or before the Closing Date.

        (c) GOVERNMENTAL CONSENTS. The execution, delivery and performance by
the Guarantor of the Operative Documents to which it is or will be a party
and the consummation by the Guarantor of the transactions contemplated by the
Operative Documents do not and will not require any Governmental Action by
any Governmental Authority.

        (d) BINDING OBLIGATION. Each Operative Document to which the
Guarantor is or will be a party has been or will be duly executed and
delivered by the Guarantor and (assuming due authorization by the other
parties thereto, other than the Lessee and the Lessee's General Partner) is
or will be the legally valid and binding obligation of the Guarantor,
enforceable against the Guarantor in accordance with its respective terms,
except as may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to or limiting creditors' rights
generally or by equitable principles relating to enforceability.

        (e) HISTORICAL FINANCIAL STATEMENTS. The Historical Financial
Statements comply as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the
Commission with respect thereto, have been prepared in accordance with GAAP
(except as may be indicated in the notes thereto) and fairly present the
consolidated financial position of the Guarantor and its consolidated
Subsidiaries as of the dates thereof and the consolidated results of their
operations and cash flows for the periods then ended (except in the case of
interim period financial information for normal year-end adjustments).
Neither Guarantor nor any of its Subsidiaries has any contingent liability,
any liability for taxes, or any other outstanding obligation that is not
reflected in the Historical Financial Statements or the notes thereto and
which in any such case is material in relation to the business, operations,
properties, assets, condition (financial or otherwise) or prospects of the
Guarantor and its Subsidiaries taken as a whole.

        (f) NO MATERIAL ADVERSE EFFECT. Since December 31, 1999, no event or
change has occurred that has caused, either in any case or in the aggregate,
a Material Adverse Effect.

        (g) LITIGATION; ADVERSE PROCEEDINGS. There are no Adverse Proceedings
pending or, to the knowledge of the Guarantor, threatened individually or in
the aggregate, (i) that seek to enjoin, either directly or indirectly, the
execution, delivery or performance by the Guarantor of the Operative
Documents or the transactions contemplated hereby or thereby, or question the
validity of the Operative Documents or the rights or remedies of the Lessor,
the Agent or the Participants with respect to the Guarantor or the Property
under the Operative Documents or (ii) could reasonably be expected to have a
Material Adverse Effect. Neither the Guarantor nor any of its Subsidiaries is
subject to or in default with respect to any final judgments, writs,
injunctions, decrees, rules or regulations of any court or any federal,
state, municipal or other

                                       37



governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, that, individually or in the aggregate,
could reasonably be expected to have a Material Adverse Effect.

        (h) PAYMENT OF TAXES. All federal and all material state, local and
foreign tax returns and reports of the Guarantor and its Subsidiaries
required to be filed by any of them have been timely filed where the failure
to file would have a Material Adverse Effect, and all taxes shown on such tax
returns to be due and payable and all assessments, fees and other
governmental charges upon the Guarantor and its Subsidiaries and upon their
respective properties, assets, income, businesses and franchises which are
due and payable have been paid when due and payable, other than those
contested in good faith by appropriate proceedings and for which adequate
reserves in accordance with GAAP have been made and subject, in the case of
the Property to the terms of the Lease. The Guarantor knows of no material
proposed tax assessment against the Guarantor or any of its Subsidiaries
which is not being actively contested by the Guarantor or such Subsidiary in
good faith and by appropriate proceedings; PROVIDED, such reserves or other
appropriate provisions, if any, as shall be required in conformity with GAAP
shall have been made or provided therefor, and PROVIDED FURTHER that, in the
case of the Property, any such contest shall be subject to the terms of the
Lease.

        (i) NO DEFAULTS. Neither the Guarantor nor any of its Subsidiaries is
in violation of or in default with respect to (i) any provision of any
Applicable Law, which violation or default could reasonably be expected to
have a Material Adverse Effect, or (ii) the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in
any indenture, mortgage, deed of trust, conditional sale contract, credit
agreement or other material agreement or instrument to which it is a party or
by which it or its properties may be bound or affected, which violation or
default could reasonably be expected to have a Material Adverse Effect. No
condition exists that, with the giving of notice or the lapse of time or
both, could constitute such a violation or default, except where the
consequences, direct or indirect, of such default or defaults, if any, could
not reasonably be expected to have a Material Adverse Effect.

        (j) GOVERNMENTAL REGULATION. The Guarantor is not subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940,
any state public utilities code or under any other federal or state statute
or regulation which may limit its ability to incur Indebtedness or which may
otherwise render all or any portion of the obligations of the Guarantor to
the Lessor, the Agent or the Participants under the Operative Documents
unenforceable.

        (k)      EMPLOYEE BENEFIT PLANS.

                (i) Neither the Guarantor nor any ERISA Affiliate maintains
        or contributes to, or has ever maintained a Pension Plan. Neither the
        Guarantor nor any ERISA Affiliate has any liability with respect to
        any post-retirement benefit under any Employee Benefit Plan which is
        a welfare plan (as defined in Section 3(1) of ERISA), other than
        liability for health plan continuation coverage described in Part 6
        of Title I(B) of ERISA, which liability for health plan coverage is
        not reasonably likely to have a Material Adverse Effect.

                                       38



                (ii) Each Employee Benefit Plan complies, in both form and
        operation, in all material respects, with its terms, ERISA and the
        Code, and no condition exists or event has occurred with respect
        to any such plan which would result in the incurrence by either the
        Guarantor or any ERISA Affiliate of any material liability, fine
        or penalty.  Each Employee Benefit Plan, related trust agreement,
        arrangement and commitment of the Guarantor or any ERISA Affiliate
        is legally valid and binding and in full force and effect in all
        material respects. No Employee Benefit Plan is being audited or
        investigated by any governmental authority or is subject to any
        pending or, to the best knowledge of Guarantor, threatened, claim
        or suit.  Neither the Guarantor nor any ERISA Affiliate nor any
        fiduciary of any Employee Benefit Plan has engaged in a prohibited
        transaction under Section 406 of ERISA or section 4975 of the Code.
        No breach of fiduciary responsibility has occurred with respect
        to any Employee Benefit Plan under Section 404 of ERISA or Section
        4975 of the Code.

                (iii) Neither the Guarantor nor any ERISA Affiliate
        contributes to or has ever contributed to any Multiemployer Plan.

                (iv) If the Guarantor or any ERISA Affiliate on or after the
        date of this Participation Agreement: (1) maintains or
        contributes to a Pension Plan; (2) contributes or has any
        material contingent obligations to any Multiemployer Plan; or (3)
        incurs a liability with respect to any post-retirement benefit
        under any Employee Benefit Plan which is a welfare plan (as defined
        in Section 3(1) of ERISA), other than liability for health plan
        continuation coverage described in Part 6 of Title I(B) of ERISA,
        which liability for health plan coverage is not reasonably likely
        to have a Material Adverse Effect, then such Guarantor or ERISA
        Affiliate shall promptly provide a written notice thereof and a
        statement affirming that no Material Adverse Effect could
        reasonably be expected to occur as a result thereof.

        (l) LICENSES, PERMITS, ETC. The Guarantor and its Subsidiaries own or
possess all licenses, permits, franchises, authorizations, patents,
copyrights, service marks, trademarks and trade names or rights thereto, that
individually or in the aggregate, are material, without known conflict with
the rights of others, the failure of which to so own or possess could
reasonably be expected to have a Material Adverse Effect. To the best
knowledge of Guarantor, no product of the Guarantor or any its Subsidiaries
infringes in any material respect on any license, permit, franchise,
authorization, patent, copyright, service mark, trademark, trade name or
other right owned by any other Person, which infringement could reasonably be
expected to have a Material Adverse Effect. To the best knowledge of the
Guarantor, there is no material violation by any Person of any right of the
Guarantor or any of its Subsidiaries with respect to any patent, copyright,
service mark, trademark, trade name or other right owned or used by the
Guarantor or any of its Subsidiaries, which violation could reasonably be
expected to have a Material Adverse Effect.

        (m) SUBSIDIARIES. SCHEDULE III identifies each Subsidiary, the
jurisdiction of its incorporation or formation, the percentage of issued and
outstanding shares of each class of its capital stock or other equity
interests owned by the Guarantor and its Subsidiaries and, if such percentage
is not 100% (excluding directors' qualifying shares as required by law), a
description of each class of its authorized capital stock and the number of
shares of each class issued and

                                       39



outstanding. Such shares owned by the Guarantor and its Subsidiaries are
owned beneficially, and of record, free of any Lien.

        (n) OFFER OF SECURITIES, ETC. Neither the Guarantor nor any Person
authorized to act on its behalf has, directly or indirectly, offered or will
offer any interest in the Property or the Lease or any other interest similar
thereto (the sale or offer of which would be integrated with the sale or
offer of such interest in the Property or the Lease), for sale to, or
solicited or will solicit any offer to acquire any of the same from, any
Person other than the Agent or Participants, the Lessor and other "accredited
investors" (as defined in Regulation D of the Securities and Exchange
Commission).

        (o) DISCLOSURE. The representations and warranties of the Guarantor
contained in any Operative Document and in any other document, certificate or
written statement furnished to the Lessor, the Agent and/or the Participants
by or on behalf of the Guarantor for use in connection with the transactions
contemplated hereby, when taken as a whole, do not contain any untrue
statement of a material fact or omit to state a material fact (known to the
Guarantor, in the case of any document not furnished by the Guarantor)
necessary in order to make the statements contained herein or therein not
misleading in light of the circumstances in which the same were made. There
are no facts known (or which should upon the reasonable exercise of diligence
be known) to the Guarantor that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect and that have
not been disclosed herein or in such other documents, certificates and
statements furnished to the Lessor, the Agent and/or the Participants for use
in connection with the transactions contemplated hereby.

moratorium or similar laws relating to or limiting creditors' rights
generally or by equitable principles relating to enforceability.

        (e) NO MATERIAL ADVERSE EFFECT. Since December 31, 1999, no event or
change has occurred that has caused, either in any case or in the aggregate,
a Material Adverse Effect with respect to Lessee.

        (f) LITIGATION; ADVERSE PROCEEDINGS. There are no Adverse Proceedings
pending or, to the knowledge of the Lessee, threatened individually or in the
aggregate, that (i) seek to enjoin, either directly or indirectly, the
execution, delivery or performance by the Lessee of the Operative Documents
or the transactions contemplated hereby or thereby, or question the validity
of the Operative Documents or the rights or remedies of the Lessor, the Agent
or the Participants with respect to the Lessee or the Property under the
Operative Documents or (ii) could reasonably be expected to have a Material
Adverse Effect. The Lessee is not subject to or in default with respect to
any final judgments, writs, injunctions, decrees, rules or regulations of any
court or any federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign,
that, individually or in the aggregate, could reasonably be expected to have

unenforceable.

and other "accredited investors" (as defined in Regulation D of the

statement of a material fact or omit to state a material fact (known to the
Lessee, in the case of any document not furnished by the Lessee) necessary in
order to make the statements contained herein or therein not misleading in
light of the circumstances in which the same were made. There are no facts
known (or which should upon the reasonable exercise of diligence be known) to

than the Tranche T Participant), and to discuss its and their affairs,
finances and accounts with its and their Responsible Officers (provided, the

discussion), all upon reasonable notice to the chief financial officer,
treasurer or the vice president of finance of the Guarantor, at such
reasonable times during normal business hours and as often as may reasonably

        Environmental Claim arising after the Closing Date at any such

        federal, state or local governmental or regulatory agency under any
        applicable Environmental Laws, which Release could reasonably be
        expected to have a Material Adverse Effect, and (2) any remedial
        action taken by the Guarantor or any other Person in response to (x)
        any Hazardous Activities the existence of which could be reasonably
        be expected to result in one or more Environmental Claims that (other

        possibility of giving rise to a Material Adverse Effect, (2) any
        Release required to be reported to any federal, state or local
        governmental or regulatory agency, which Release could reasonably be
        expected to have a Material Adverse Effect, and (3) any request for
        information from any Governmental Authority that suggests such
        Governmental Authority  is investigating whether the Guarantor or any
        of its Subsidiaries may be potentially responsible for any Hazardous

        have a Material Adverse Effect;

               (4) prompt written notice describing in reasonable detail (1)

        of its Subsidiaries to maintain in full force and effect all material
        Governmental Actions required under any Environmental Laws for their
        respective operations, which failure to maintain could reasonably be

        action to be taken by the Guarantor or any of its Subsidiaries to
        modify current operations in a manner that could reasonably be
        expected to subject the Guarantor or any of its Subsidiaries to any
        additional material obligations or requirements under any
        Environmental Laws, which obligations or requirements could
        reasonably be expected to have a Material Adverse Effect; and

                (5) with reasonable promptness, such other documents and
        information as from time to time may be reasonably requested by the
        Lessor or the Agent in relation to any matters disclosed pursuant to

        have, individually or in the aggregate, a Material Adverse Effect,
        and (ii) make an appropriate response to any Environmental Claim
        against the Guarantor or such  Subsidiaries and discharge any
        obligations it may have to any Person thereunder where (other than in

        expected to have, individually or in the aggregate, a Material
        Adverse Effect.

        (vii) COMPLIANCE WITH LAWS. The Guarantor will comply, and shall
     cause each of its Subsidiaries and all other Persons, if any, on or
     occupying any facilities or properties of the Guarantor or any or its
     Subsidiaries to comply, with the requirements of all applicable laws,
     rules, regulations and orders of any Governmental Authority (including
     all Environmental Laws), noncompliance with which could (other than in
     the case of the Property) reasonably be expected to have, individually
     or in the aggregate, a Material Adverse Effect.

Agreement remains in effect or any amount is owing to any Participant, the
Lessor or the Agent hereunder or under any other Operative Document, the
Guarantor shall, and shall cause each of its Subsidiaries to, comply with each

to (a) send any default notices required before a Default can become an Event
of Default, or (b) bring a lawsuit against the Lessee to enforce the
Operative Documents when an Event of Default has occurred and is continuing,
then the Lessor shall send the notice or bring the suit, and the Lessor shall
prosecute any such suit with reasonable diligence using reputable counsel.
However, if the Agent is not a member of the Required Participants voting
pursuant to this SECTION 11.2(c) in favor of the giving of any such notice or
the bringing of any such suit, then the Lessor may require that it first
receive the written agreement (in form reasonably acceptable to the Lessor)
of the members of the Required Participants so voting to indemnify the Agent
and the Lessor from and against all costs, liabilities and claims that may be
incurred by or asserted against the Lessor because of the action the Required
Participants direct the Agent or the Lessor to take. In no event shall any
Participant instigate any suit or other action directly against the Lessee
with respect to the Operative Documents or the Property, even if such
Participant would, but for this agreement, be entitled to do so as a third
party beneficiary or otherwise under the Operative Documents.

     (d) In the event the Lessee or its designee fails to purchase the
Property after any exercise of its Purchase Option or Expiration Date
Purchase Obligation or following the occurrence and continuance of an Event
of Default, the Lessor shall, if the Required Participants shall agree in
writing, bring suit against the Lessee to enforce the Operative Documents in
such form as shall be recommended by reputable counsel, and thereafter the
Lessor shall prosecute the suit with reasonable diligence in accordance with
the advice of reputable counsel. If, after the occurrence and continuance of
an Event of Default, the Lessor acquires the interests of the Lessee in any
of the Property as a result of such suit or otherwise (unless the Lessor
acquires such interests through a Voluntary Retention of the Property and
pays to each Participant all amounts payable to such Participant hereunder,
including, without limitation, such Participant's Participation Interest in
all amounts payable by the Lessee on the Designated Payment Date and any
Shortfall Amount), the Lessor shall thereafter proceed with reasonable
diligence to sell the Property in a commercially reasonable manner to one or
more bona fide third party purchasers and shall in any event endeavor to
consummate the sale of the entire Property (through a single sale of the
entire Property or a series of sales of parts) within five (5) years
following the date the Lessor recovers possession of the Property at the best
price or prices the Lessor believes are reasonably attainable within such
time. Further, after the Designated Payment Date and prior to the Lessor's
sale of the entire Property, the Lessor shall retain a property management
company experienced in the area where the Property is located to manage the
operation of the Property and

                                        67



pursue the leasing of any completed Improvements which are part of the
Property. The Lessor shall not retain an Affiliate of the Lessor to act as
the property manager except under a bona fide, arms-length management
contract containing commercially reasonable terms. Further, after the
Designated Payment Date and until the Lessor sells the Property, the Lessor
shall (i) endeavor in good faith to maintain, or shall obtain the agreement
of one or more of such tenants to maintain, the Property in good order and
repair, (ii) procure and maintain casualty insurance against risks
customarily insured against by owners of comparable properties, in amounts
sufficient to eliminate the effects of coinsurance, (iii) keep and allow each
Participant (other than the Tranche T Participant) to review accurate books
and records covering the operation of the Property, and (iv) pay prior to
delinquency all taxes and assessments lawfully levied against the Property.

     (e) Notwithstanding the foregoing, Defaulting Participants shall have no
voting or consent rights under this SECTION 11.2 and no rights to require the
Lessor to call a meeting pursuant to SECTION 11.2(d) until they cease to be
Defaulting Participants. During any period that any Defaulting Participants
have no voting rights under this SECTION 11.2, only the Commitment
Percentages of the other Participants that still have voting rights will be
considered for purposes of determining the Required Participants.

SECTION 11.3     ACTIONS BY LESSOR GENERALLY. Subject to the limitations set
forth in SECTION 11.2 and the provisions of SECTION 11.11:

     (a) The Lessor shall have the exclusive right to take any action and to
exercise any available powers, rights and remedies to enforce the obligations
of the Lessee under the Operative Documents, or to refrain from taking any
such action or exercising any such power, right or remedy.

     (b) The Lessor shall be entitled to (i) give any consent, waiver or
approval requested by the Lessee with respect to any construction or other
approval contemplated in the Lease or any Construction Agency Agreement or
(ii) waive or consent to any adverse title claims affecting the Property,
PROVIDED that, in either case, such action will not have a material adverse
effect on the Lessee's obligations or ability to make the payments required
under the Operative Documents, the Lessor's rights and remedies under the
Operative Documents or any Participant's rights hereunder.

     SECTION 11.4     CONFLICTS. Notwithstanding anything to the contrary
herein contained, the Lessor shall be entitled, even over the objection of
each Participant or the Required Participants, (i) to take any action
required of the Lessor by, or to refrain from taking any action prohibited
by, the Operative Documents or any law, rule or regulation to which the
Lessor is subject (PROVIDED, that this Section shall not be construed to
authorize the Lessor to take any action required by a modification of the
Operative Documents prohibited by SECTION 11.2), and (ii) after notice to the
Participants (other than the Tranche T Participant), to bring and prosecute a
suit against the Lessee in the form recommended by and in accordance with
advice of reputable counsel at any time when a breach of the Operative
Documents by the Lessee shall have put the Lessor (or any of its officers or
employees) at risk of criminal prosecution or significant liability to third
parties or at any time after the Lessee or its designee fails to purchase the
Property on the Designated Payment Date. Nothing herein contained shall be
construed to require the Lessor to agree to modify the Operative Documents or
to take any action or refrain

                                        68



from taking any action in any manner that could increase the Lessor's
liability to the Lessee or others, that could reduce or postpone payments to
which the Lessor is entitled thereunder, or that could reduce the scope and
coverage of the indemnities provided for the Lessor's benefit therein.

     SECTION 11.5      REFUSAL TO GIVE CONSENTS OR FUND. If any Participant
declines to consent to any amendment, modification, waiver, release or
consent for which such Participant's consent is requested or required by
reason of this Agreement, or if any Participant fails to pay any amount owed
by it hereunder, the Lessor shall have the right, but not the obligation and
without limiting any other remedy of the Lessor, to terminate such
Participant's rights to receive any further payments under SECTION 3 of this
Agreement by paying such Participant a termination fee equal to the total of:

         (i)      all amounts actually advanced by such Participant to the
         Lessor under SECTION 3.4 hereof before the termination; excluding,
         however, any such amounts that were repaid to such Participant
         before the termination by actual payments made to such Participant
         by the Lessor of, or the Lessor's offset against, sums representing:

                  (A)  Such Participant's Commitment Percentage (as then in
                  effect) times any payments of Rent received by the Lessor
                  under the Lease; plus

                  (B)  Such Participant's Commitment Percentage (as then in
                  effect) times any sales proceeds or proceeds of any
                  casualty or condemnation or any payments of Asset
                  Termination Value received by the Lessor under the Lease;
                  and

        (ii) Such Participant's Commitment Percentage (as then in effect),
        times:

                  (A)  the then accrued but unpaid Basic Rent or, during the
                  Construction Period in respect of the Expansion
                  Improvements, accrued but unpaid interest or yield, and
                  Commitment Fees due hereunder; plus

                  (B)  interest on past due amounts described in the
                  preceding clause (A) computed at the Federal Funds
                  Effective Rate; plus

                  (C)  interest on any amounts (other than interest itself)
                  past due from the Lessee or its designees under the
                  Operative Documents, computed at the Federal Funds
                  Effective Rate.

     SECTION 11.6      REQUIRED REPAYMENTS. Each Participant shall repay to
the Lessor, upon written request or demand by the Lessor (i) any sums paid by
the Lessor to such Participant under this Agreement from, or that were
computed by reference to, any Rent or other amounts which the Lessor shall be
required to return or pay over to another party, whether pursuant to any
bankruptcy or insolvency law or proceeding or otherwise and (ii) any interest
or other amount that the Lessor is also required to pay to another party with
respect to such sums. Such repayment by any Participant shall not constitute
a release of such Participant's right to receive such Participant's
Commitment Percentage (as then in effect) times the amount of any such Rent
or any such other amount (or any interest thereon) that the Lessor may later
recover.

                                        69




     SECTION 11.7      INDEMNIFICATION. Each Participant agrees to indemnify
and defend the Lessor (to the extent not reimbursed by the Lessee within ten
(10) days after demand) from and against such Participant's Commitment
Percentage (as then in effect) of any and all liabilities, obligations,
claims, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this
SECTION 11.7 collectively called "COVERED LIABILITIES") which to any extent
(in whole or in part) may be imposed on, incurred by or asserted against the
Lessor growing out of, resulting from or in any other way associated with the
Property or the Operative Documents (including the enforcement thereof,
whether exercised upon the Lessor's own initiative or upon the direction of
the Required Participants) and the transactions and events at any time
associated therewith or contemplated therein. The foregoing indemnification
shall apply whether or not such Covered Liabilities are in any way or to any
extent caused, in whole or in part, by any negligent act or omission of any
kind by the Lessor; PROVIDED, that no Participant shall be obligated under
this SECTION 11.7 to indemnify the Lessor (i) for Covered Liabilities that
would not have been incurred but for a Voluntary Retention of the Property by
the Lessor, (ii) for Covered Liabilities incurred in connection with any
transfer or assignment by the Lessor of its right to receive Rent or its
rights and interests in and to the Property, the Operative Documents or this
Agreement to its Affiliates, or (iii) for that portion or percentage, if any,
of any of the Covered Liabilities which is proximately caused by: (A) the
Lessor's own gross negligence or willful misconduct; (B) any representation
made by the Lessor in the Operative Documents that is false in any material
respect and that the Lessor knew was false at the time of the Lessor's
execution of the Operative Documents; or (C) Lessor Liens not claimed by,
through or under any of the Participants. After each Participant has paid its
Commitment Percentage (as then in effect) of any Covered Liabilities, each
Participant shall be entitled to payment from the Lessor of an amount equal
to the Adjusted Percentage (as defined below) of any payments subsequently
received by the Lessor as Excess Reimbursement (as defined below) for such
Covered Liabilities. As used in this Section "ADJUSTED PERCENTAGE" as of any
date of determination shall equal (i) such Participant's Commitment
Percentage then in effect, divided by (ii) the sum of the Commitment
Percentages of all Participants who have paid the Lessor their respective
shares of the Covered Liabilities at issue. As used in this Section, the term
"EXCESS REIMBURSEMENT" shall mean, for the Covered Liabilities at issue,
amounts reimbursed or paid by the Lessee to or on behalf of the Lessor on
account of such Covered Liabilities in excess of an amount equal to the
product of (i) such Covered Liabilities, multiplied by (ii) the Commitment
Percentages of any Participants that have not paid the Lessor their
respective Percentages of such Covered Liabilities.

     SECTION 11.8      APPLICATION OF PAYMENTS RECEIVED FROM DEFAULTING
PARTICIPANT AS A CURE FOR PAYMENT DEFAULTS. If after a failure to make a
payment required by SECTION 3.4, any Defaulting Participant cures such
failure, in whole or in part, by paying to the Lessor all or part of such
payment and interest thereon at the Late Payment Rate, then the Lessor shall
apply the payments so made to the Lessor, net of the costs of collecting such
payments (the "NET CURE PROCEEDS"), or other funds available to the Lessor
equal to the Net Cure Proceeds, in the following order before applying the
same to any other purpose:

         (i)      first, to make payments to the Lessor itself equal to its
         Excess Investment (if any) until the Lessor shall no longer have any
         Excess Investment; and

                                        70




         (ii)     second, to make further Advances to the Lessee under this
         Agreement to the extent the Lessor is required or deems it
         appropriate to do so; PROVIDED, that such further Advances do not
         cause the total Property Cost to exceed the sum of the Commitments.

     SECTION 11.9      ORDER OF APPLICATION. For purposes of this Agreement,
the Lessor shall be entitled, but not required, to apply any payments
received from the Lessee under the Operative Documents to satisfy costs
incurred by the Lessor because of any sale under the Lease before applying
such payments to satisfy the Lessee's other obligations, regardless of how
the Lessee may have designated such payments.

     SECTION 11.10     INVESTMENTS PENDING DISPUTE RESOLUTION; OVERNIGHT
INVESTMENTS. Whenever the Lessor in good faith determines that it does not
have all information needed to determine how payments to Participants must be
made on account of any then existing Participation Interests which the Lessor
has received, or whenever the Lessor in good faith determines that there is
any dispute among the Participants about payments which must be made on
account of Participation Interests actually received by the Lessor, the
Lessor may choose to defer the payments which are the subject of such missing
information or dispute. However, to minimize any such deferral, the Lessor
shall attempt diligently to obtain any missing information needed to
determine how payments to the Participants must be made. Also, pending any
such deferral, or if the Lessor is otherwise required to invest funds pending
distribution to the Participants, the Lessor shall invest funds equal to (i)
the total of the Commitment Percentages of all Participants to whom payments
have not been made with respect to the Participation Interests at issue,
times (ii) the total payments at issue. In addition, the Lessor shall
endeavor to invest payments of Participation Interests it receives after
12:00 noon, Chicago time, on the day in question that are to be paid to a
Participant on the next Business Day pursuant to SECTION 3; PROVIDED that the
Lessor shall have no liability to any Participant if the Lessor is unable to
make such investments. Investments by the Lessor shall be in the overnight
federal funds market pending distribution, and the interest earned on each
Dollar of principal so invested shall be paid to the Person entitled to
receive such Dollar of principal when the principal is paid to such Person.

     SECTION 11.11     AGENT TO EXERCISE LESSOR'S RIGHTS. The Lessor has
assigned its interest in the Lease to the Agent, for the benefit of the
Participants, pursuant to the Assignment of Lease. To the extent provided
therein, the rights, remedies, duties and responsibilities of the Lessor
contained in this SECTION 11 and in the other Operative Documents with
respect thereto shall be exercisable by, binding upon and inure to the
benefit of the Agent, for the benefit of the Participants.

     SECTION 11.12     EXCULPATORY PROVISIONS REGARDING THE LESSOR. Subject
to the provisions of SECTION 11.11, each Participant hereby irrevocably
authorizes the Lessor to take such actions on its behalf as are expressly
vested in or delegated to the Lessor by the terms of this Agreement and the
other Operative Documents, together with such powers as are reasonably
incidental thereto. The provisions of the following Sections of this
Agreement are hereby incorporated by reference into this SECTION 11.12,
substituting the word "Lessor" for "Agent" therein:

         (i)      SECTION 14.1 - second sentence.

         (ii)     SECTION 14.2 - all.

         (iii)    SECTION 14.3 - all.

         (iv)     SECTION 14.4 - all.

                                 SECTION 12

                      TRANSFERS OF PARTICIPANTS' INTERESTS

     SECTION 12.1      RESTRICTIONS ON AND EFFECT OF TRANSFER BY
PARTICIPANTS. No Participant may (without the prior written consent of the
Agent, not to be unreasonably withheld) assign, convey or otherwise transfer
(including pursuant to a participation) all or any portion of its right,
title or interest in, to or under its Participation Interest or any of the
Operative Documents or the Property, PROVIDED that (x) any Participant (other
than the Tranche T Participant) may pledge its interest without the consent
of the Agent or the Lessee to any Federal Reserve Bank, (y) without the prior
written consent of the Agent, any Participant (other than the Tranche T
Participant) may transfer all or any portion of its interest to any Affiliate
of such Participant or to any other existing Participant, and (z) the Tranche
T Participant may not assign, convey or otherwise transfer any portion of its
right, title or interest in, to or under its Participation Interest or any of
the Operative Documents or the Property without the prior written consent of
the Agent; PROVIDED, FURTHER, that in the case of any transfer (other than a
transfer to an Affiliate of the relevant Participant pursuant to CLAUSE (y)
above) each of the following conditions and any other applicable conditions
of the other Operative Documents are satisfied:

     (a) REQUIRED NOTICE AND EFFECTIVE DATE. Any Participant desiring to
effect a transfer of its interest shall give written notice of each such
proposed transfer to the Lessee and the Agent at least five (5) Business Days
prior to such proposed transfer, setting forth the name of such proposed
transferee, the percentage or interest to be retained by such Participant, if
any, and the date on which such transfer is proposed to become effective. All
reasonable out-of-pocket costs (including, without limitation, legal
expenses) incurred by the Lessor, the Lessee, the Agent or any Participant in
connection with any such disposition by a Participant under this SECTION 12.1
shall be borne by such transferring Participant. In the event of a transfer
under this SECTION 12.1, any expenses incurred by the transferee in
connection with its review of the Operative Documents and its investigation
of the transactions contemplated thereby shall be borne by such transferee or
the relevant Participant, as they may determine, but shall not be considered
costs and expenses which the Lessee is obligated to pay or reimburse under
SECTION 9. Any such proposed transfer shall become effective upon the later
of (i) the date proposed in the transfer notice referred to above and (ii)
the date on which all conditions to such transfer set forth in this SECTION
12.1 shall have been satisfied.

                                        72



     (b) ASSUMPTION OF OBLIGATIONS. Any transferee pursuant to this SECTION
12.1 shall execute and deliver to the Agent and the Lessee an Assignment and
Acceptance in substantially the form attached as EXHIBIT H ("ASSIGNMENT AND
ACCEPTANCE"), duly executed by such transferee and the transferring
Participant, and a letter in substantially the form of the Participant's
Letter attached hereto as EXHIBIT I ("PARTICIPANT'S LETTER"), and thereupon
the obligations of the transferring Participant under the Operative Documents
shall be proportionately released and reduced to the extent of such transfer.
Upon any such transfer as above provided, the transferee shall be deemed to
be bound by all obligations (whether or not yet accrued) under, and to have
become a party to, all Operative Documents to which its transferor was a
party, shall be deemed the pertinent "Participant" for all purposes of the
Operative Documents and shall be deemed to have made that portion of the
payments pursuant to this Participation Agreement previously made or deemed
to have been made by the transferor represented by the interest being
conveyed; and each reference herein and in the other Operative Documents to
the pertinent "Participant" shall thereafter be deemed a reference to the
transferee, to the extent of such transfer, for all purposes. Upon any such
transfer, the Agent shall deliver to each Participant, the Lessor and the
Lessee a new SCHEDULE I and a new SCHEDULE II to this Agreement, each revised
to reflect the relevant information for such new Participant and the
Commitment of such new Participant (and the revised Commitment of the
transferor Participant if it shall not have transferred its entire interest).

     (c) EMPLOYEE BENEFIT PLANS. No Participant may make any such assignment,
conveyance or transfer to or in connection with any arrangement or
understanding in any way involving any employee benefit plan (or its related
trust), as defined in Section 3(3) of ERISA, or with the assets of any such
plan (or its related trust), as defined in Section 4975(e)(1) of the Code.

     (d) REPRESENTATIONS. Notwithstanding anything to the contrary set forth
above, no Participant may assign, convey or transfer its interest to any
Person, unless such Person shall have delivered to the Agent and the Lessee a
certificate (which certification may be contained within the Assignment and
Acceptance executed and delivered by such Person) confirming the accuracy of
the representations and warranties set forth in SECTION 8 with respect to
such Person (other than as such representation or warranty relates to the
execution and delivery of Operative Documents) and representing that such
Person has, independently and without reliance upon the Agent, any other
Participant or, except to the extent of the Lessee's representations made
under the Operative Documents when made, the Lessee, and based on such
documents and information as it has deemed appropriate, made its own
appraisal of and investigation into this transaction, the Property and the
Lessee and made its own decision to enter into this transaction.

     (e) AMOUNTS; AGENT'S FEE. Any transfer of Participation Interests shall
be in a principal amount which is equal to or greater than $5,000,000;
PROVIDED, that no such minimum transfer limitation shall be imposed on a
transfer of a Tranche B Participation Interest or a Tranche C Equity
Interest. Each transferring Participant shall pay to the Agent a transfer fee
of $2,500.

     (f) APPLICABLE LAW. Such transfer shall comply with Applicable Law and
shall not require registration under any securities law applicable thereto.

                                        73



     (g) EFFECT. From and after any transfer of its Participation Interest
the transferring Participant shall be released, to the extent assumed by the
transferee, from its liability and obligations hereunder and under the other
Operative Documents to which such transferor is a party in respect of
obligations to be performed on or after the date of such transfer. Upon any
transfer by a Participant as above provided, any such transferee shall be
deemed a "Participant" for all purposes of such documents and each reference
herein to a Participant shall thereafter be deemed a reference to such
transferee for all purposes to the extent of such transfer, except as the
context may otherwise require. Notwithstanding any transfer as provided in
this SECTION 12.1, the transferor shall be entitled to all benefits accrued
and all rights vested prior to such transfer, including, without limitation,
rights to indemnification under this Participation Agreement or any other
Operative Document.

     SECTION 12.2      COVENANTS AND AGREEMENTS OF PARTICIPANTS.

     (a) PARTICIPATIONS. Each Participant covenants and agrees that it will
not grant participations in its Participation Interest to any Person (a
"SUB-PARTICIPANT") unless such participation complies with Applicable Law and
does not require registration under any securities law applicable thereto and
such Sub-Participant (i) is a bank or other financial institution and (ii)
represents and warrants, in writing, to such Participant for the benefit of
the Participants, the Lessor and the Lessee that (A) no part of the funds
used by it to acquire an interest in any Participation Interest constitutes
assets of any "employee benefit plan" (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA, or "plan" (as defined in Section
4975(e)(1) of the Code) and (B) such Sub-Participant is acquiring its
interest for investment purposes without a view to the distribution thereof;
PROVIDED that notwithstanding the foregoing the Tranche T Participant shall
not grant any participation in its Participation Interest to any
Sub-Participant without the prior written consent of the Agent. Any such
Person shall require any transferee of its interest in its Participation
Interest to make the representations and warranties set forth in the
preceding sentence, in writing, to such Person for its benefit and the
benefit of the Participants, the Lessor and Lessee. In the event of any such
sale by a Participant of a participating interest in its Participation
Interest to a Sub-Participant, such Participant's obligations under this
Participation Agreement and under the other Operative Documents shall remain
unchanged, such Participant shall remain solely responsible for the
performance thereof, such Participant shall remain the holder of its
Participation Interest for all purposes under this Participation Agreement
and under the other Operative Documents, and the Lessor, the Agent and,
except as set forth in SECTION 12.2(b), 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
under the other Operative Documents.

     (b) TRANSFEREE INDEMNITIES. Each Sub-Participant shall be entitled to
the benefits of SECTIONS 13.5, 13.6, 13.7 and 13.10 with respect to its
participation in the Participation Interests outstanding from time to time;
PROVIDED that no Sub-Participant shall be entitled to receive any greater
amount pursuant to such Sections than the transferor Participant would have
been entitled to receive in respect of the amount of the participation
transferred by such transferor Participant to such Sub-Participant had no
such transfer or participation occurred.

                                        74



     SECTION 12.3      FUTURE PARTICIPANTS. Each Participant shall be deemed
to be bound by and, upon compliance with the requirements of this SECTION 12,
will be entitled to all of the benefits of the provisions of, this
Participation Agreement.

                                     SECTION

                                 INDEMNIFICATION

     SECTION 13.1      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 Closing Date or after the Expiration Date, in any way
relating to or arising out of:

     (a) any of the Operative Documents or any of the transactions
contemplated thereby or any violation thereof, or any investigation,
litigation or proceeding in connection therewith and any amendment,
modification or waiver in respect thereof;

     (b) the Property, the Lease, any permitted sublease or any part

management, possession, operation, rental, lease, sublease, repossession,
maintenance, repair, alteration, modification, addition or substitution,
storage, transfer of title, redelivery, use, financing, refinancing,
disposition, operation, condition, sale (including, without limitation, any
sale pursuant to Sections 16.2, 16.3, 17.2(c), 17.2(e), 17.2(h) or 17.4 of
the Lease or any sale pursuant to Articles XX or XXII of the Lease, except
for any amounts payable pursuant to SECTION 13.2 hereof), return or other
disposition of all or any part or any interest in the Property 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 foreign, federal, state

                              exceed the maximum Expansion Improvements
                              Residual Value Guarantee Amount.

                           (B)    If any Lessor Party incurs any such claims
                    or expenses for which the Lessee is not obligated to
                    indemnify such Lessor Party pursuant to CLAUSE (5) of
                    this SECTION 13.1, such claims shall, if such Lessor
                    Party shall so request by a written notice to the Lessor
                    and the Lessor shall give its prior written consent
                    thereto, be capitalized pursuant to SECTION 3.7(e)(ii).

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 Lease or any other Operative Document.

     SECTION 13.2      END OF TERM INDEMNITY.

     (a) If the Lessee elects the Remarketing Option and it is determined, in
accordance with the provisions of Section 22.1(j) of the Lease, that there
would, after giving effect to the proposed remarketing transaction, be a
Shortfall Amount, then as a condition to the Lessee's right to complete the
remarketing of the Property pursuant to Section 22.1 of the Lease, the

                                        77



Lessee shall cause to be delivered to the Lessor at least 30 days prior to
the Expiration Date, at the Lessee's sole cost and expense, a report from an
appraiser selected by the Lessor and reasonably satisfactory to the Agent and
the Required Participants and the Lessee in form and substance reasonably
satisfactory to the Lessor, the Agent and the Required 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 the Property from
that anticipated for such date in the Appraisal delivered on the Closing Date.

     (b) On 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 Property due to:

         (i)      extraordinary wear and tear, excessive usage, failure to
         maintain, to repair, to restore, to rebuild or to replace, failure
         to comply with the Lease and 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 Modification made to, or any rebuilding of, the
         Property or any part thereof by the Lessee or any sublessee; or

         (iii)    the existence of any Hazardous Activity, Hazardous Substance
         or Environmental Violations; or

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

         (v)      any condemnation of any portion of the Property pursuant to
         Article XV of the Lease; or

         (vi)     any use of the Property or any part thereof by the Lessee
         or any sublessee other than as facilities of the type described in
         Recital B to this Agreement; or

         (vii)    any grant, release, dedication, transfer, annexation or
         amendment made  pursuant to Section 12.2 of the Lease; or

         (viii)   the failure of the Lessor to have a good and marketable fee
         estate in the Property, as required by the Operative Documents, free
         and clear of all Liens (including Permitted Liens) and exceptions to
         title, except (A) such Liens or exceptions to title that existed on
         the Closing Date and were disclosed in the title report and approved
         by the Agent; (B) Liens that would be released as a result of
         consummation of the Remarketing Option or other required sale of the
         Property; (C) Lessor Liens and (D) easements, rights-of-way,
         agreements and other rights permitted by Section 12.2 of the Lease.

     SECTION 13.3      ENVIRONMENTAL INDEMNITY. Without limitation of the
other provisions of this SECTION 13, the Lessee hereby agrees to indemnify,
hold harmless and defend each Indemnitee, on an After Tax Basis, 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 any loss of value of the Property), damages, liabilities,
fines,

                                        78

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 foreign, federal, state or local
government agency, which such Indemnitee becomes subject to because of its
involvement with the Property, the transactions contemplated by the Operative
Documents or any other matter referred to in PARAGRAPHS (a) through (i) of
SECTION 13.1 arising in whole or in part, out of:

     (a) the presence on or under the Property of any Hazardous Substances,
or any Releases or discharges of any Hazardous Substances on, under, from or
onto the Property;

     (b) any activity, including, without limitation, construction, carried

the Existing Owner or any predecessor in title, or any other Persons
(including such Indemnitee), in connection with the handling, treatment,
removal, storage, decontamination, cleanup, 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 the Property;

     (c) loss of or damage to any property or the environment (including,
without limitation, cleanup 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;

     (e) any residual contamination on or under the Property, or affecting
any natural resources, or 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 Environmental Laws; or

     (f) any material inaccuracies, misrepresentations, misstatements, and
omissions and any conflicting information contained in or omitted from the
Environmental Audit;

PROVIDED, HOWEVER, the Lessee shall not be required to indemnify any
Indemnitee under this SECTION 13.3 for (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

                                        79




caused or contributed to such Claim), (2) any Imposition or other
claims for Taxes of the type(s) described in SECTION 13.5, or (3) any Claims
of the type(s) described in SECTIONS 13.2, 13.6, 13.7, 13.8 and 13.10. 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 Lease or any other Operative Document.

     SECTION 13.4     PROCEEDINGS IN RESPECT OF CLAIMS. With respect to any
amount that the Lessee is requested by an Indemnitee to pay by reason of
SECTION 13.1 or 13.3, 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, such Indemnitee shall notify the Lessee of the commencement
thereof, and if the Construction Period limitation on indemnification set
forth in CLAUSE (5) of the proviso to SECTION 13.1 does not apply, 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 information 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
possibility of imposition of criminal liability or any risk of material civil
liability on such Indemnitee or will involve a material risk of the sale,
forfeiture or loss of, or the creation of any Lien (other than a Permitted
Exception) on, the Property or any part thereof unless, in the case of civil
liability or Lien, the Lessee shall have posted a bond or other security
satisfactory to the relevant Indemnitee in respect to such risk 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) an Event of Default
under the Lease has occurred and is continuing. 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
13.1 or 13.3 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.

         Each Indemnitee shall at the expense of the Lessee cooperate with
and supply the Lessee with such information and documents reasonably
requested by the Lessee as are necessary or advisable for the Lessee to
participate in any action, suit or proceeding to the extent permitted by
SECTION 13.1 or 13.3. Unless an Event of Default under the 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 13.1 or 13.3 without the prior written consent of
the Lessee, which consent shall not be unreasonably withheld, unless such

                                        80




Indemnitee waives its right to be indemnified under SECTION 13.1 or 13.3 with
respect to such Claim.

         Upon payment in full of any Claim by the Lessee pursuant to SECTION
13.1 or 13.3 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 13.1 or 13.3
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.

     SECTION 13.5      GENERAL IMPOSITIONS INDEMNITY.

     (a) INDEMNIFICATION. The Lessee shall pay and assume liability for, and
does hereby agree to indemnify, protect and defend the Property and all
Indemnitees, and hold them harmless against, all Impositions on an After Tax
Basis.

     (b) PAYMENTS.

         (i)      Subject to the terms of SECTION 13.5(f), the Lessee shall
         pay or cause to be paid all Impositions directly to the taxing
         authorities where feasible and otherwise to the Indemnitee, as
         appropriate, and the Lessee shall at its own expense, upon such
         Indemnitee's reasonable request, furnish to such Indemnitee copies
         of official receipts or other satisfactory proof evidencing such
         payment.

         (ii)     In the case of Impositions for which no contest is
         conducted pursuant to SECTION 13.5(f) and which the Lessee pays
         directly to the taxing authorities, the Lessee shall pay such
         Impositions prior to the latest time permitted by the relevant
         taxing authority for timely  payment. In the case of Impositions
         for which the Lessee reimburses an Indemnitee, the Lessee shall
         do so within twenty (20) days after receipt by the Lessee of
         demand by such Indemnitee describing in reasonable detail the
         nature of the Imposition and the basis for the demand (including
         the computation of the amount payable), but in no event shall the
         Lessee be required to pay such reimbursement prior to thirty
         (30) days before the latest time permitted  by the relevant
         taxing authority for timely payment. In the case of Impositions
         for which a contest is conducted pursuant to SECTION 13.5(f), the
         Lessee shall pay such Impositions or reimburse such Indemnitee
         for such Impositions, to the extent not previously paid or
         reimbursed pursuant to SECTION 13.5(a), prior to the latest time
         permitted by the relevant taxing authority for timely payment
         after conclusion of all contests under SECTION 13.5(f).

         (iii)    Impositions imposed with respect to the Property for a
         billing period during which the Lease expires or terminates (unless
         the Lessee has exercised the

                                        81




         Renewal Option or the Purchase Option with respect to the Property)
         shall be adjusted and prorated on a daily basis between the Lessee
         and the Lessor, whether or not such Imposition is imposed before or
         after such expiration or termination and each party shall pay or
         reimburse the other for each party's pro rata share thereof.

     (c) REPORTS AND RETURNS. (i) The Lessee shall be responsible for
preparing and filing any real and personal property or ad valorem tax returns
in respect of the Property. In case any other report or tax return shall be
required to be made with respect to any obligations of the Lessee under or
arising out of SECTION 13.5(a) and of which the Lessee has knowledge or
should have knowledge, the Lessee, at its sole cost and expense, shall notify
the relevant Indemnitee of such requirement and (except if such Indemnitee
notifies the Lessee that such Indemnitee intends to prepare and/or file such
report or return, which preparation and/or filing to the extent related to
the transactions contemplated hereby shall be at Lessee's cost and expense;
PROVIDED, THAT Lessee shall not be responsible for such Indemnitee's costs
and expenses of preparing and filing such report or return, if such
Indemnitee files such report or return without so notifying Lessee and Lessee
also files such report or return) (A) to the extent required or permitted by
and consistent with Applicable Law, make and file in its own name such
return, statement or report; and (B) in the case of any other such return,
statement or report required to be made in the name of such Indemnitee,
advise such Indemnitee of such fact and prepare such return, statement or
report for filing by such Indemnitee or, where such return, statement or
report shall be required to reflect items in addition to any obligations of
the Lessee under or arising out of SECTION 13.5(a), provide such Indemnitee
at the Lessee's expense with information sufficient to permit such return,
statement or report to be properly made with respect to any obligations of
the Lessee under or arising out of SECTION 13.5(a). Such Indemnitee shall,
upon the Lessee's request and at the Lessee's expense, provide any data
maintained by such Indemnitee (and not otherwise available to or within the
control of the Lessee) with respect to the Property which the Lessee may
reasonably require to prepare any required tax returns or reports. Each
Indemnitee agrees to use its best efforts to send to the Lessee a copy of any
written request or other notice that the Indemnitee receives with respect to
any reports or returns required to be filed with respect to the Property or
the transactions contemplated by the Operative Documents, it being understood
that no Indemnitee shall have any liability for failure to provide such
copies; PROVIDED that in the event of any such failure by any Indemnitee, the
Lessee shall have no obligation to indemnify such Indemnitee for any
penalties or fines imposed that would not have been imposed but for such
failure.

     (d) INCOME INCLUSIONS. If as a result of the payment or reimbursement by
the Lessee of any expenses of the Lessor or the payment of any Transaction
Expenses incurred in connection with the transactions contemplated by the
Operative Documents, the Lessor or any Indemnitee or Affiliate shall suffer a
net increase in any federal, state, local or foreign income tax liability,
the Lessee shall indemnify such Persons (without duplication of any
indemnification required by SECTION 13.5(a)) on an After Tax Basis for the
amount of such increase. The calculation of any such net increase shall take
into account any current or future tax savings realized or reasonably
expected to be realized by such Person in respect thereof, as well as any
interest, penalties and additions to tax payable by the Lessor, or any
Indemnitee or such Affiliate, in respect thereof.

                                        82




     (e)      WITHHOLDING TAXES. As between the Lessee on one hand, and the
Lessor or the Agent or any Participant on the other hand, the Lessee shall be
responsible for, and, subject to the provisions of SECTIONS 13.5(g) and (h),
the Lessee shall indemnify and hold harmless the Lessor, the Agent and the
Participants (without duplication of any indemnification required by SECTION
13.5(a)) on an After Tax Basis against, any obligation for United States or
foreign withholding taxes imposed in respect of payments with respect to the
Participation Interests or with respect to Rent payments under the Lease or
payments of the Asset Termination Value, Lease Balance or Purchase Option
Price (and, if the Lessor, the Agent or any Participant receives a demand for
such payment from any taxing authority, the Lessee shall discharge such
demand on behalf of the Lessor, the Agent or such Participant).

     (f)      CONTESTS OF IMPOSITIONS.

         (i)      If a written claim is made against any Indemnitee or if
         any proceeding shall be commenced against such Indemnitee
         (including a written notice of such proceeding), for any
         Impositions, such Indemnitee shall promptly notify the Lessee in
         writing and shall not take action with respect to such claim or
         proceeding without the consent of the Lessee for thirty (30)
         days after the receipt of such notice by the Lessee; PROVIDED,
         however, that, in the case of any such claim or proceeding, if
         action shall be required by law or regulation to be taken prior to
         the end of such 30-day period, such Indemnitee shall, in such
         notice to the Lessee, inform the Lessee of such shorter period,
         and no action shall be taken with respect to such claim or
         proceeding without the consent of the Lessee before 2 days before
         the end of such shorter period; PROVIDED, FURTHER, that the
         failure of such Indemnitee to give the notices referred to
         this sentence shall not diminish the Lessee's obligation
         hereunder except to the extent such failure precludes the Lessee
         from contesting all or part of such claim.

         (ii)     If, within thirty (30) days of receipt of such notice
         from the Indemnitee (or such shorter period as the Indemnitee
         has notified the Lessee is required by law or regulation for the
         Indemnitee to commence such contest), the Lessee shall request in
         writing that such Indemnitee contest such Imposition, the
         Indemnitee shall, at the expense of the Lessee, in good faith
         conduct and control such contest (including, without limitation,
         by pursuit of appeals) relating to the validity, applicability
         or amount of such Impositions (PROVIDED, however, that (A) if such
         contest involves a tax other than a tax on net income and can be
         pursued independently from any other proceeding involving a tax
         liability of such Indemnitee, the Indemnitee, at the Lessee's
         request, shall allow the Lessee to conduct and control such
         contest and (B) in the case of any contest, the Indemnitee may
         request the Lessee to conduct and control such contest) by,
         in the sole discretion of the Person conducting and controlling
         such contest, (1) resisting  payment thereof, (2) not paying the
         same except under protest, if protest is necessary and proper, (3)
         if the payment be made, using reasonable efforts to obtain a refund
         thereof in appropriate administrative and judicial proceedings, or
         (4) taking such other action as is reasonably requested by the
         Lessee from time to time.

         (iii)    The party controlling any contest shall consult in good
         faith with the non-controlling party and shall keep the
         non-controlling party reasonably informed as to the conduct of
         such contest; PROVIDED, that all decisions ultimately shall be
         made in the

                                        83




         sole discretion of the controlling party. The parties agree that
         an Indemnitee may at any time decline to take further action with
         respect to the contest of any Imposition and may settle such
         contest if such Indemnitee shall waive its rights to any indemnity
         from the Lessee that otherwise would be payable in respect of
         such claim (and any future claim by any taxing authority, the
         contest of which is precluded by reason of such resolution of
         such claim) and shall pay to the Lessee any amount previously paid
         or advanced by the Lessee pursuant to this SECTION 13.5 by way of
         indemnification or advance for the payment of an Imposition other
         than expenses of such contest.

         (iv)     Notwithstanding the foregoing provisions of this SECTION
         13.5, an Indemnitee shall not be required to take any action and the
         Lessee shall not be permitted to contest any Impositions in its own
         name or that of the Indemnitee unless (A) the Lessee shall have
         agreed to pay and shall pay to such Indemnitee on demand and on an
         After Tax Basis all reasonable costs, losses and expenses that such
         Indemnitee actually incurs in connection with contesting such
         Impositions, including, without limitation, all reasonable legal,
         accounting and investigatory fees and disbursements, (B) in the
         case of a claim that must be pursued in the name of an Indemnitee
         (or an Affiliate  thereof), the amount of the potential indemnity
         (taking into account all similar or logically related claims that
         have been or could be raised in any audit involving such Indemnitee
         for which the Lessee may be liable to pay an indemnity under this
         SECTION 13.5) exceeds $100,000, (C) the Indemnitee shall have
         reasonably determined that the action to be taken will not result
         in any material danger of sale, forfeiture or loss of the Property,
         or any part thereof or interest therein, will not interfere with
         the payment of Rent, and will not result in risk of criminal
         liability, (D) if such contest shall involve the payment of the
         Imposition prior to the contest, the Lessee shall provide to the
         Indemnitee an interest-free advance in an amount equal to the
         Imposition that the Indemnitee is required to pay (with no
         additional net after-tax cost to such Indemnitee), (E) in the case
         of a claim that must be pursued in the name of an Indemnitee (or an
         Affiliate thereof), the Lessee shall have provided to such
         Indemnitee an opinion of independent tax counsel selected by the
         Indemnitee and reasonably satisfactory to the Lessee stating that a
         reasonable basis exists to contest such claim (or, in the case of an
         appeal of an adverse determination, an opinion of such counsel to
         the effect that there is substantial authority for the position
         asserted in such appeal) and (F) no Event of Default hereunder
         shall have occurred and be continuing. In no event shall an
         Indemnitee be required to appeal an adverse judicial determination
         to the United States Supreme Court. In addition, an Indemnitee
         shall not be required to contest any claim in its name (or that of
         an Affiliate) if the subject matter thereof shall be of a
         continuing nature and shall have previously been decided adversely
         by a court of competent jurisdiction pursuant to the contest
         provisions of this SECTION 13.5, unless there shall have been a
         change in law (or interpretation thereof) and the Indemnitee shall
         have received, at the Lessee's expense, an opinion of independent
         tax counsel selected by the Indemnitee and reasonably acceptable to
         the Lessee stating that as a result of such change in law (or
         interpretation thereof), it is more likely than not that the
         Indemnitee will prevail in such contest.

     (g) DOCUMENTATION OF WITHHOLDING STATUS. Each Participant (or any
successor thereto or transferee thereof) that is organized under the laws of
a jurisdiction outside of the United States of America shall:

                                        84




         (i)      on or before the date it becomes a party to any Operative
         Document, deliver to the Lessor and the Lessee any certificates,
         documents, or other evidence that shall be required by the Code or
         Treasury Regulations issued pursuant thereto to establish its
         exemption from United States Federal withholding requirements,
         including two valid, duly completed, original copies of
         Internal Revenue Service Form W-8BEN or Form W-8ECI or
         successor applicable form, properly and duly executed,
         certifying in each case that such party is entitled to receive
         payments pursuant to the Operative Documents without deduction
         or withholding of United States Federal income taxes and is a
         foreign person thereby entitled to an exemption from the United
         States backup withholding taxes;

         (ii)     on or before the date that any such form described above
         expires or becomes obsolete, or after the occurrence of any event
         requiring a change in the most recent such form previously delivered
         to the Lessor and the Lessee, deliver to the Lessor and the Lessee
         two further valid, duly completed, original copies of any such form
         or certification, properly and duly executed; and

         (iii)    comply from time to time with all United States laws and
         regulations  with regard to such withholding tax exemptions.

     (h) LIMITATION ON TAX INDEMNIFICATION. The Lessee shall not be required
to indemnify any Indemnitee, or to pay any increased amounts to any
Indemnitee or tax authority with respect to any withholding taxes pursuant to
this SECTION 13.5 to the extent that (i) any obligation to withhold, deduct,
or pay amounts with respect to Tax existed on the date such Indemnitee became
a party to any Operative Document (and, in such case, the Lessee may deduct
and withhold such Tax from payments pursuant to the Operative Documents), or
(ii) such Indemnitee fails to comply with the provisions of SECTION 13.5(g)
(and, in such case, the Lessee may deduct and withhold all Taxes required by
law as a result of such noncompliance from payments made by the Lessee
pursuant to the Operative Documents). With respect to any transferee of any
Participant (including a transfer resulting from any change in the
designation of the lending office of a Participant), the transferee shall not
be entitled to any greater payment or indemnification under this SECTION 13.5
than the transferor would have been entitled to.

     SECTION 13.6      FUNDING LOSSES. If any payment of any Advance or any
portion of any Participation Interest is made on any day other than the last
day of an Interest Period applicable thereto, or if the Lessee fails to
utilize the proceeds of any purchase of Participation Interests after notice
has been given to the Lessor or any Participant in accordance with SECTION 3
or 6, the Lessee shall reimburse the Lessor and each Participant on an After
Tax Basis within fifteen (15) days after demand for any resulting loss or
expense incurred by it, including (without limitation) any loss incurred in
obtaining, liquidating or employing deposits from third parties, provided
that the Lessor or such Participant, as the case may be, shall have delivered
to the Lessee a certificate as to the amount of such loss or expense, which
certificate shall be conclusive in the absence of manifest error. The Lessor
or such Participant, as applicable, will, at the request of the Lessee,
furnish such additional information concerning the determination of such loss
as the Lessee may reasonably request.

     SECTION 13.7      REGULATION D COMPENSATION. For so long as the Lessor
or any Participant is required to increase its existing reserve percentage
against "Eurocurrency

                                        85




Liabilities" (or any other category of liabilities which include deposits by
reference to which the interest rate on its Participation Interest in any
Advance is determined or any category of extensions of credit or other assets
which includes loans by a non-United States office of the Lessor or such
Participant, as applicable, to United States residents), and, as a result,
the cost to the Lessor or such Participant (or such Participant's Funding
Office) of purchasing or maintaining its Participation Interest in any
Advance is increased, then the Lessor or such Participant may require the
Lessee to pay, on an After Tax Basis, contemporaneously with each payment of
interest on the Advances an additional amount on the Participation Interest
of such Participant in the Advances at a rate per annum up to but not
exceeding the excess of (i) (A) the applicable Eurodollar Rate divided by (B)
one minus the Eurocurrency Reserve Requirements over (ii) the applicable
Eurodollar Rate.

     SECTION 13.8      BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR
UNFAIR. If on or prior to the first day of any Interest Period:

     (a) deposits in Dollars (in the applicable amounts) are not being
offered to the Agent in the relevant market for such Interest Period or any
Participant shall advise the Agent that the Eurodollar Rate as determined by
the Agent will not adequately and fairly reflect the cost to such Participant
of funding its Participation Interest in any Advance for such Interest
Period; or

     (b) any Participant determines that, by reason of the adoption, on or
after the date of this Participation Agreement, of any applicable law, rule
or regulation, or any change therein, or any change in the interpretation or
administration thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof,
or compliance by any Participant (or its Funding Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or governmental agency, it is restricted, directly or
indirectly, in the amount it may hold of (i) a category of liabilities that
includes deposits by reference to which, or on the basis of which, the
interest rate applicable to Advances based on the Eurodollar Rate is directly
or indirectly determined, or (ii) the category of assets which includes
Advances based on the Eurodollar Rate; the Agent shall forthwith give notice
thereof to the Lessee and the Participants, whereupon the obligation of the
Participants to provide funding at rates based upon the Eurodollar Rate shall
be suspended and, until the Agent notifies the Lessee that the circumstances
giving rise to such suspension no longer exist, each outstanding Advance
shall begin to bear interest at the Alternate Base Rate on the last day of
the then current Interest Period applicable thereto.

      SECTION 13.9      ILLEGALITY. If, on or after the date of this
Participation Agreement, the adoption of any applicable law, rule or
regulation, or any change therein, or any change in the interpretation or
administration thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof,
or compliance by any Participant (or its Funding Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency, shall make it unlawful or impossible for
any Participant (or its Funding Office) to purchase, maintain or fund its
Participation Interest in any Advance and such Participant shall so notify
the Agent, the Agent shall forthwith give notice thereof to the other
Participants and the Lessee, whereupon until such Participant notifies the
Lessee and the Agent that the circumstances giving rise to such

                                        86




suspension no longer exist, the obligation of such Participant to purchase
its Participation Interest in any Advance shall be suspended. Before giving
any notice to the Agent pursuant to this Section, such Participant shall, if
practicable, with the consent of the Lessee (which consent shall not
unreasonably be withheld), designate a different Funding Office if such
designation will avoid the need for giving such notice and will not, in the
judgment of such Participant, be otherwise disadvantageous to such
Participant. If such notice is given (i) the Lessee shall be entitled upon
its request to a reasonable explanation of the factors underlying such notice
and (ii) each outstanding Participation Interest in any Advance of such
Participant then outstanding shall begin to bear interest at the Alternate
Base Rate either (a) on the last day of the then current Interest Period
applicable to such Advance if such Participant may lawfully continue to
maintain and fund such Participation Interest to such day or (b) immediately
if such Participant shall determine that it may not lawfully continue to
maintain and fund such Participation Interest to such day.

     SECTION 13.10     INCREASED COST AND REDUCED RETURN. (a) In the event
that the adoption of any applicable law, rule or regulation, or any change
therein or in the interpretation or application thereof by any Governmental
Authority, central bank or comparable agency charged with the interpretation
or administration thereof or compliance by the Lessor or any Participant with
any request or directive after the date hereof (whether or not having the
force of law) of any such authority, central bank or comparable agency:

         (i)      does or shall subject the Lessor or such Participant to any
         additional tax of any kind whatsoever with respect to the Operative
         Documents or any Advance made by such Person or any purchase of a
         Participation Interest in any Advance, or change the basis or the
         applicable rate of taxation of payments to the Lessor or such
         Participant of its Participation Interest or any other amount
         payable hereunder (except for the imposition of or change in any tax
         on or measured by the overall net income of the Lessor or such
         Participant (other than any such tax imposed by means of
         withholding));

         (ii)     does or shall impose, modify or hold applicable any
         reserve, special deposit, insurance assessment, compulsory loan or
         similar requirement against assets held by, or deposits or other
         liabilities in or for the account of, advances or loans by, or other
         credit extended by, or any other acquisition of funds by, any office
         of the Lessor or such Participant which are not otherwise included
         in determination of the rate of interest on Advances hereunder; or

         (iii) does or shall impose on the Lessor or such Participant any other
         condition;

and the result of any of the foregoing is to increase the cost to the Lessor
or such Participant of making or maintaining its Advances or purchasing or
maintaining its Participation Interest in any Advance or to reduce any amount
receivable hereunder with respect thereto, then, in any such case (A) if such
Advances constitute Expansion Improvements Advances, prior to the Completion
Date with respect to the Expansion Improvements, the Lessor shall pay to the
Participants and the Lessee shall pay to the Lessor, and thereafter the
Lessee shall promptly pay, or (B) with respect to all other Advances, the
Lessee shall promptly pay the Lessor or such Participant, as the case may be,
upon its demand, on an After Tax Basis any additional amounts necessary to
compensate the Lessor or such Participant for such increased cost or reduced

                                        87




amount receivable which the Lessor or such Participant deems to be material
as determined by the Lessor or such Participant.

     (b) If the Lessor or any Participant shall have determined that, after
the date hereof, the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency has or would have the effect of reducing
the rate of return on capital of the Lessor or such Participant, as the case
may be (or any entity directly or indirectly controlling the Lessor or such
Participant), as a consequence of the Lessor's or such Participant's
obligations under the Operative Documents to a level below that which the
Lessor or such Participant (or any entity directly or indirectly controlling
the Lessor or such Participant), as applicable, could have achieved but for
such adoption, change, request or directive (taking into consideration its
policies with respect to capital adequacy) by an amount deemed by the Lessor
or such Participant to be material, then from time to time, within 15 days
after demand by the Lessor or such Participant (with a copy to the Agent),
(i) with respect to Expansion Improvements, prior to the Completion Date with
respect to the Expansion Improvements, the Lessor shall pay to the
Participants and the Lessee shall pay to the Lessor, and thereafter the
Lessee shall pay, or (ii) with respect to the Existing Facility and the
Tenant Improvements, the Lessee shall pay to the Lessor or such Participant,
as the case may be, on an After Tax Basis, such additional amount or amounts
as will compensate such Participant (or its parent) or the Lessor for such
reduction.

     (c) The Lessor and each Participant will promptly notify the Lessee and
the Agent of any event of which it has knowledge, occurring after the date
hereof, which will entitle the Lessor or such Participant, as the case may
be, to compensation pursuant to this Section and will, if practicable, with
the consent of the Lessee (which consent shall not unreasonably be withheld),
designate a different Funding Office or take any other reasonable action if
such designation or action will avoid the need for, or reduce the amount of,
such compensation and will not, in the judgment of the Lessor or such
Participant, as applicable, be otherwise disadvantageous to the Lessor or
such Participant. A certificate of the Lessor or any Participant claiming
compensation under this Section and setting forth in reasonable detail its
computation of the additional amount or amounts to be paid to it hereunder
shall be conclusive in the absence of manifest error. In determining such
amount, the Lessor or such Participant, as the case may be, may use any
reasonable averaging and attribution methods. This Section shall survive the
termination of this Participation Agreement and payment of the outstanding
Advances and Participation Interests.

     SECTION 13.11    SUBSTITUTION OF PARTICIPANT. If (i) the obligation of
any Participant to purchase or maintain its Participation Interest has been
suspended pursuant to this SECTION 13, or (ii) any Participant has demanded
compensation or given notice of its intention to demand compensation under
SECTION 13.10, the Lessee shall have the right, with the assistance of the
Agent, to seek one or more mutually satisfactory substitute banks or
financial institutions (which may be one or more of the Participants) to
replace such Participant under the Operative Documents.

                                        88



     SECTION 13.12     INDEMNITY PAYMENTS IN ADDITION TO RESIDUAL VALUE
GUARANTEE AMOUNT. The Lessee acknowledges and agrees that its obligations to
make indemnity payments under this SECTION 13 are separate from, in addition
to, and do not reduce, its obligation to pay, any Residual Value Guarantee
Amount under the Lease; PROVIDED, that in the event the Lessee elects the
Remarketing Option, the Lessee shall only be required to pay any Shortfall
Amount to the extent set forth in SECTION 13.2 hereof.

     SECTION 13.13     LIMITATIONS ON INDEMNIFICATION. Notwithstanding any
other provisions of SECTIONS 13.1 or 13.10 hereof or Section 24.1 of the
Lease (the "INDEMNIFICATION SECTIONS") to the contrary, with respect to the
Expansion Improvements only, prior to the Completion Date with respect to the
Expansion Improvements only, the Lessee (i) shall be obligated to indemnify
only the Lessor for any Claims of the Lessor under SECTION 13.1 or costs or
losses under SECTION 13.10 or losses under Section 24.1 of the Lease
(collectively "LESSOR LOSSES") PROVIDED, that such Lessor Losses shall
include costs and expenses of the Lessor under SECTION 13.14 and (ii) shall
have no right to contest any matter covered under SECTIONS 13.1 or 13.10
hereof or SECTION 24.1 of the Lease, notwithstanding the language of SECTIONS
13.1 or 13.10 hereof or SECTION 24.1 of the Lease, if such matter is not
fully indemnifiable by the Lessee because of the operation of this SECTION
13.13 or because such matter is not indemnifiable due to the exclusions set
forth in CLAUSE 5(A)(2) of the proviso to SECTION 13.1, or clause (i)(B) of
the proviso to Section 24.1 of the Lease.

      SECTION 13.14     LESSOR INDEMNIFICATION.

     (a) INDEMNIFIED LOSSES. Prior to the Completion Date with respect to the
Expansion Improvements, the Lessor shall pay, indemnify, protect, defend,
save and keep harmless each Indemnitee (other than the Lessor, its
Affiliates, successors, assigns, directors, shareholders, partners, officers,
employees and agents) (an "INDEMNIFIED PARTY") on an After Tax Basis from and
against any Losses (as hereinafter defined) arising from Covered Matters (as
hereinafter defined), subject to the limitations set forth in this SECTION
13.14.

     (b) DEFINITIONS. For purposes of this SECTION 13.14, the following terms
shall have the meanings set forth below:

         "COVERED MATTERS" means each of the matters set forth in the
Indemnification Sections (subject to the exceptions and exclusions set forth
therein) relating to the Expansion Improvements.

         "LOSSES" means each of the Claims, Impositions, losses, costs or
expenses indemnified against pursuant to any of the Indemnification Sections
relating to or arising in respect of the Expansion Improvements (subject to
the exceptions and exclusions set forth therein) and arising prior to the
Completion Date with respect to the Expansion Improvements.

     (c) NO INDEMNIFICATION FOR CERTAIN MATTERS. The Lessor shall not be
required to indemnify or hold harmless any Indemnified Party hereunder
against any matter referred to in clause (a) of this SECTION 13.14 to the
extent of the exceptions or exclusions from indemnification contained in any
of the Indemnification Sections.

                                        89




     (d) LIMITATIONS ON INDEMNIFICATION BY LESSOR. The Lessor's obligation to
indemnify and hold harmless any Indemnified Party under this Section:

         (i)      is not an individual or personal obligation of the Lessor,
         but solely its obligation in its capacity as Lessor, and nothing
         herein shall be construed as creating any liability on the Lessor,
         individually or personally, to pay, indemnify or hold harmless any
         Indemnified Party under this Section;

         (ii)     is not an obligation binding on the Lessor except to the
         extent of any payments received by the Lessor pursuant to the
         Indemnification Sections;

         (iii)    shall be paid and discharged solely and exclusively from
         amounts received by the Lessor pursuant to the Indemnification
         Sections, and it is expressly agreed by each Indemnified Party that
         the sole recourse of each such Person for payment or discharge of
         the indemnification obligations created under this SECTION 13.14
         shall be to such amounts paid by the Lessee or the Guarantor
         pursuant to the Indemnification Sections; and

         (iv)     is the sole and exclusive right of each Indemnified Party
         against the Lessor, and any right to proceed against the Lessor
         individually or otherwise under common law, federal or state
         securities laws or otherwise for indemnification or contribution in
         connection with the matters covered by this SECTION 13.14, is hereby
         expressly waived by each Indemnified Party (other than claims that
         may be made against the Lessor, individually or personally, for
         fraud, gross negligence or willful misconduct).

Nothing in this SECTION 13.14 is intended as or should be construed as a
limitation on the right of any Indemnified Party to make indemnification,
contribution or other claims of any kind against the Lessee or the Guarantor, to
the extent that such claims otherwise may be made, with respect to any matter,
including indemnification for Losses of the type referred to in this SECTION
13.14.

     (e) REPAYMENT TO THE LESSOR. To the extent that any payments made
pursuant to the Indemnification Sections are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid
by the Lessor to a trustee, debtor in possession, receiver or other Person
under any Bankruptcy Code, common law or equitable cause, then to such
extent, the Indemnified Parties who received any such payments from the
Lessor (or any portion thereof) shall repay on an After Tax Basis any such
amounts to the Lessor, or as may otherwise be directed by a court of
competent jurisdiction, provided that no such Indemnified Party shall be
obligated to repay to the Lessor an amount greater than the payment received
by such Indemnified Party from the Lessor.

     (f) SURVIVAL, REINSTATEMENT. The indemnification obligations of the
Lessor under this Section shall survive and be reinstated to the same extent,
for the same period and in the same manner as the indemnification obligations
of the Lessee under the Indemnification Sections.

     (g) INDEMNIFICATION PROCEDURES. The right of any Indemnified Party to
seek indemnification from the Lessor under this SECTION 13.14 is subject to
and conditioned upon compliance by any such Indemnified Party with the
notice, cooperation, appointment of counsel, contest rights and other
provisions in the Indemnification Sections (including, without limitation,
the exceptions to or exclusions from indemnification set forth therein) as
fully as if such Sections

                                        90



were set forth herein, except that any reference in the Indemnification
Sections to the Lessee shall be deemed to be a reference to the Lessor or, if
the Lessor so directs in any case, the Lessor and/or the Lessee for purposes
of this Section.

                                    SECTION 14

                                    THE AGENT

     SECTION 14.1      APPOINTMENT. Each Participant hereby irrevocably
designates and appoints the Agent as the agent of such Participant under this
Agreement and the other Operative Documents, and each Participant irrevocably
authorizes the Agent, in such capacity, to take such action on its behalf
under the provisions of this 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 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 Agreement,
the Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with 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 Agreement or any other Operative Document or
otherwise exist against the Agent.

     SECTION 14.2      DELEGATION OF DUTIES. The Agent may execute any of its
duties under this 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 Agent shall not be
responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

     SECTION 14.3      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 Agreement or any other
Operative Document (except for its or such Person's own gross negligence or
willful misconduct or negligence with respect to the handling of funds) 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, the Lessee, the Construction Agent, Lessee's
General Partner or the Guarantor or any officer thereof contained in this
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 Agreement or any other Operative
Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Operative
Document or for any failure of the Lessor, the Lessee, the Construction
Agent, Lessee's General Partner or the Guarantor to perform its obligations
hereunder or thereunder. The 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 Agreement or any other Operative
Document, or to inspect the properties, books or records of the Lessor, the
Lessee, the Construction Agent, Lessee's General Partner or the Guarantor.

                                        91




     SECTION 14.4      RELIANCE BY AGENT. The 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 Agent. The Agent shall be fully
justified in failing or refusing to take any action under this Agreement or
any other Operative Document unless it shall first receive such advice or
concurrence of the Required Participants as it deems appropriate or 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 Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and
the other Operative Documents in accordance with a request of the Required
Participants, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Participants.

     SECTION 14.5      NOTICE OF DEFAULT. The Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
unless the Agent has received notice from a Participant, the Lessor, the
Lessee, the Construction Agent, Lessee's General Partner or the Guarantor
describing such Default or 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 give notice thereof to the other parties hereto. Subject to the
provisions of SECTION 11 hereof, the Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed
by the Required Participants; provided 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
Default or Event of Default as it shall deem advisable in the best interests
of the Participants.

      SECTION 14.6      NON-RELIANCE ON AGENT AND OTHER PARTICIPANTS. Each
Participant 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, the
Lessee, the Construction Agent, Lessee's General Partner or the Guarantor,
shall be deemed to constitute any representation or warranty by the Agent to
any Participant. Each Participant represents to the Agent that it has,
independently and without reliance upon the 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, the Construction Agent, Lessee's General Partner, the Guarantor
and the Property and made its own decision to purchase its Participation
Interest hereunder and enter into this Agreement. Each Participant also
represents that it will, independently and without reliance upon the 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 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, the Lessee, the Construction Agent, Lessee's General Partner and
the Guarantor. Except for notices, reports and other documents expressly

                                        92




required to be furnished to the Participants by the Agent hereunder, the
Agent shall not have any duty or responsibility to provide any Participant
with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or creditworthiness
of the Lessor, the Lessee, the Construction Agent, Lessee's General Partner
or the Guarantor which may come into the possession of the Agent or any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

     SECTION 14.7      INDEMNIFICATION. The Participants 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 their respective Commitment Percentages in effect on the date on
which indemnification is sought under this SECTION 14.7 (or, if
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 in effect 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 (including,
without limitation, at any time following the payment of the Participation
Interests) be imposed on, incurred by or asserted against the Agent in any
way relating to or arising out of, the Commitments, this 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 Agent. The agreements in this SECTION 14.7 shall survive
the payment of the Participation Interests and all other amounts payable
hereunder.

     SECTION 14.8      AGENT IN ITS INDIVIDUAL CAPACITY. The Agent and its
Affiliates may make loans to, accept deposits from and generally engage in
any kind of business with the Lessor, the Lessee, the Construction Agent, the
Lessee's General Partner or the Guarantor as though the Agent were not the
Agent hereunder and under the other Operative Documents. With respect to its
Participation Interest purchased by it, the Agent shall have the same rights
and powers under this Agreement and the other Operative Documents as any
Participant and may exercise the same as though it were not the Agent, and
the terms "Participant" and "Participants" shall include the Agent in its
individual capacity.

     SECTION 14.9      SUCCESSOR AGENT. The Agent may resign as Agent upon 30
days' notice to the Participants, the Lessor and the Lessee. If the Agent
shall resign as Agent under this Agreement and the other Operative Documents,
then the Required Participants shall appoint a successor Agent for the
Participants. Any such 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 (provided that so long as no Default or Event of Default
exists, the successor Agent shall be approved by the Lessee (which approval
shall not be unreasonably withheld)). Upon such appointment (a) 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 (b) the former

                                        93




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 Agreement. If no successor Agent has accepted appointment as
Agent by the date which is 30 days following a resigning Agent's notice of
resignation, the resigning Agent's resignation shall nevertheless thereupon
become effective and the Participants shall perform all of the duties of the
Agent hereunder until such time, if any, as the Required Participants appoint
a successor Agent as provided above. After any retiring Agent's resignation
as Agent, all of the provisions of this SECTION 14 shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was Agent under
this Agreement and the other Operative Documents.

                                SECTION 15

                               MISCELLANEOUS

     SECTION 15.1      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, payment of the Advances and the Participation
Interests and any disposition thereof and shall be and continue in effect
notwithstanding any investigation made by any party or 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.

     SECTION 15.2      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 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 on an After Tax Basis from and against
any liability arising out of such breach of this representation.

     SECTION 15.3      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 and delivered (i) personally,
(ii) by a nationally recognized overnight courier service, (iii) by mail (by
registered or certified mail, return receipt requested, postage prepaid) or
(iv) by facsimile, in each case directed to the address of such Person as
indicated on SCHEDULE II. Any such notice shall be effective upon receipt or
refusal.

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.

     SECTION 15.4      COUNTERPARTS. This Participation Agreement may be
executed by the parties hereto in separate counterparts, each of which when
so executed and delivered shall

                                        94




be an original, but all such counterparts shall together constitute but
one and the same instrument.

     SECTION 15.5      HEADINGS, ETC. The Table of Contents and headings of
the various Sections of this Agreement are for convenience of reference only
and shall not modify, define, expand or limit any of the terms or provisions
hereof.

     SECTION 15.6      PARTIES IN INTEREST. Except as expressly provided
herein, none of the provisions of this Participation Agreement are intended
for the benefit of any Person except the parties hereto. Subject to the
provisions of Section 25.1 of the Lease, the Lessee shall not assign or
transfer any of its rights or obligations under the Operative Documents
without the prior written consent of the Lessor, the Agent and the
Participants.

     SECTION 15.7      GOVERNING LAW. THIS PARTICIPATION AGREEMENT SHALL IN
ALL RESPECTS BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK (EXCLUDING ANY
CONFLICT-OF-LAW OR CHOICE-OF-LAW RULES (OTHER THAN SECTION 5-1401 OR SECTION
5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK) WHICH MIGHT
LEAD TO THE APPLICATION OF THE INTERNAL LAWS OF ANY OTHER JURISDICTION) AS TO
ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE EXCEPT AS TO MATTERS
RELATING TO THE CREATION OF LEASEHOLD INTERESTS, AND THE CREATION, ATTACHMENT
AND PERFECTION OF SECURITY INTERESTS OR EXERCISE OF REMEDIES WITH RESPECT
THERETO, WHICH MATTERS SHALL BE GOVERNED BY THE LAWS OF THE STATE IN WHICH
THE PROPERTY IS LOCATED SUBJECT TO SECTIONS 9-103 AND 1-105 OF THE APPLICABLE
UNIFORM COMMERCIAL CODE.

     SECTION 15.8      SEVERABILITY. Any provision of this Participation
Agreement that 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.

     SECTION 15.9      LIABILITY LIMITED. (a) The Lessee, the Construction
Agent, the Guarantor, the Lessee's General Partner, the Agent, and the
Participants each acknowledge and agree that the Lessor shall not be liable
or accountable under any circumstances whatsoever in its individual capacity
for or on account of any statements, representations, warranties, covenants
or obligations stated to be those of the Lessor, except for its own gross
negligence or willful misconduct or negligence in the handling of funds and
as otherwise expressly provided herein or in the other Operative Documents,
and it is understood and agreed that all obligations of the Lessor to the
Lessee, the Construction Agent, the Lessee's General Partner, the Guarantor,
the Agent and any Participant under the Operative Documents are solely
nonrecourse obligations (except as otherwise expressly provided therein)
enforceable only against the Lessor's interest in the Property.

     (b) No Participant shall have any obligation to any other Participant or
to the Lessee, the Construction Agent, the Lessee's General Partner, the
Guarantor, the Lessor or the Agent with respect to transactions contemplated
by the Operative Documents, except those obligations

                                        95




of such Participant expressly set forth in the Operative Documents or except
as set forth in the instruments delivered in connection therewith, and no
Participant shall be liable for performance by any other party hereto of such
other party's obligations under the Operative Documents except as otherwise
so set forth.

     SECTION 15.10     FURTHER ASSURANCES. The parties hereto shall promptly
cause to be taken, executed, acknowledged or delivered, at the sole expense
of the Lessee, all such further acts, conveyances, documents and assurances
as the other parties may from time to time reasonably request in order to
carry out and effectuate the intent and purposes of this Participation
Agreement, the other Operative Documents, and the transactions contemplated
hereby and thereby (including, without limitation, the preparation, execution
and filing of any and all Uniform Commercial Code financing statements and
other filings or registrations which the parties hereto may from time to time
request to be filed or effected). The Lessee, at its own expense and without
need of any prior request from any other party, shall take such action as may
be necessary (including any action specified in the preceding sentence), or
(if the Lessor shall so request) as so requested, in order to maintain and
protect all security interests provided for hereunder or under any other
Operative Document.

     SECTION 15.11     SUBMISSION TO JURISDICTION. Each of the Lessee, the
Construction Agent, the Lessee's General Partner and the Guarantor hereby
submits to the nonexclusive jurisdiction of the United States District Court
for the Southern District of New York and of any New York State court sitting
in New York County for purposes of all legal proceedings arising out of or
relating to the Operative Documents or the transactions contemplated hereby.
Each of the Lessee, the Construction Agent, the Lessee's General Partner and
the Guarantor irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of
any such proceeding brought in such a court and any claim that any such
proceeding brought in such a court has been brought in an inconvenient forum.

     SECTION 15.12     CONFIDENTIALITY. The Lessor, the Agent and each
Participant (other than the Tranche T Participant) represent that they will
maintain the confidentiality of the transactions contemplated by, and of any
written or oral information provided under, the Operative Documents by or on
behalf of the Lessee, the Construction Agent, the Lessee's General Partner or
the Guarantor (hereinafter collectively called "Confidential Information"),
subject to the Lessor's, the Agent's and each such Participant's (a)
obligation to disclose any such Confidential Information pursuant to a
request or order under applicable laws and regulations or pursuant to a
subpoena or other legal process, (b) right to disclose any such Confidential
Information to its bank examiners, Affiliates, auditors, counsel and other
professional advisors and to other Participants, (c) right to disclose any
such Confidential Information in connection with any litigation or dispute
involving the Participants and the Lessee, the Construction Agent, the
Lessee's General Partner, the Guarantor or any of its Subsidiaries and
Affiliates and (d) right to provide such information to Sub-Participants,
prospective Sub-Participants to which sales of participating interests are
permitted pursuant to this Participation Agreement and prospective assignees
to which assignments of interests are permitted pursuant to this
Participation Agreement, but only if (i) such Sub-Participant, prospective
Sub-Participant or prospective assignee agrees in writing to maintain the
confidentiality of such information on terms substantially similar to those
of this Section as if it were a "Participant" party hereto and (ii) the
Lessee, the Construction Agent, the Lessee's

                                        96




General Partner and the Guarantor receive copies of such written agreement
prior to the release of such information. Notwithstanding the foregoing, any
such information supplied to a Participant, Sub-Participant, prospective
Sub-Participant or prospective assignee under this Participation Agreement
shall cease to be Confidential Information if it is or becomes known to such
Person by other than unauthorized disclosure, or if it becomes a matter of
public knowledge.

     SECTION 15.13     WAIVER OF JURY TRIAL. EACH OF THE LESSEE, THE
CONSTRUCTION AGENT, THE GUARANTOR, THE AGENT, THE LESSEE'S GENERAL PARTNER,
THE LESSOR, AND EACH PARTICIPANT HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THE
OPERATIVE DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY.

                            [SIGNATURE PAGE FOLLOWS]

                                        97

Agreement to be duly executed by their respective officers thereunto duly
authorized as of the day and year first above written.
