acknowledged, the parties hereto agree as follows:

payment of Transaction Expenses; and

                           (iii)        acquire the Phase I
Facility and, if
requested by the Lessee, the Phase II Facility (using funds provided by the

             Upon the applicable Lease
Commencement Date, subject to the terms and conditions hereof and of the other
Operative Documents, the Lessor shall lease the applicable portion of the
Property, as lessor, to the Lessee under the Lease.

                           (b)        Lessee Covenants
 .  The Lessee shall, on or prior to the Closing

             Section 3.2      
Participants'
Commitments. Subject
to the terms and conditions hereof, each Participant other than the Lessor
severally shall purchase a Participation Interest in the Advances being made by
the Lessor at the request of the Lessee from time to time during the Commitment
Period by making available to the Lessor on each Funding Date an amount in
immediately available funds equal to such Participants' Commitment Percentage
(as then in effect) of the amount of the Advance being funded on such Funding
Date. Notwithstanding any other provision hereof, no Participant shall be
obligated to purchase its Participation Interest in any Advance if (i) the
amount of such purchase would exceed its Available Commitment, or (ii) if,
after giving effect to the proposed Advance, the outstanding aggregate amount
of such Participant's Participation Interest in the Advances would exceed such
Participant's Commitment.  Lessor shall
repay the Participation Interests, together with accrued interest and yield
thereon as provided herein to the extent such amounts
are received under the Lease.

             Section 3.3      Procedures
for Acquisition of the Property. The Lessee shall give
the Lessor and the Agent prior written notice not later than 12:00 noon,
Chicago time, three Business Days prior to the proposed applicable Land
Interest Acquisition Date (unless the initial Land Interest Acquisition Date is

Advance, in which case such notice may be given not later than 12:00 noon,
Chicago time, on such Land Interest Acquisition Date), pursuant to an Acquisition
Request substantially in the form of Exhibit A (an "Acquisition
Request"), specifying: (i) the proposed Land Interest Acquisition
Date, (ii) the portion of the Property to be acquired, (iii) the Existing Owner
of such portion of the Property, and (iv) the date on which the Lessee will
request the Lessor to fund the Property Acquisition Costs in respect of such
portion of the Property.  The Agent
shall provide notice of each such Acquisition Request to each Participant.

             Section
3.4      Procedures for Advances. With respect to each
funding of an Advance, the Lessee shall give the Lessor and the Agent prior
written notice not later than 12:00 noon, Chicago time, three Business Days
prior to the proposed Funding Date (other than for the Advance, if any, on the
Closing Date, if such Advance is to be an Alternate Base Rate Advance, in which
case such notice may be given not later than 12:00 noon, Chicago time, 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, (iii) the Lessee's election to cause all or a specified
portion of such Advance to bear interest or yield by reference to the
Eurodollar Rate or the Alternate Base Rate and including, in the case of a
Eurodollar Rate Advance, the initial Interest Period therefor (all on a Tranche
by Tranche basis), (iv) the payees of such Advance, (v) that the Advance will
be used to fund Property Acquisition Costs in respect of the portion of the
Property specified in such Funding Request, and (vi) that to the knowledge of
the Lessee, no Default or Event of Default (other than a Limited Default or a
Limited Event of Default, provided that if a Limited Default or a
Limited Event of Default exists, the provisions of Section 6.5 shall
apply) 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.  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 a portion of the Property, pay the Property Acquisition
Costs therefor to the Existing Owner thereof, and (B) in the case of an Advance
for Transaction Expenses, pay the specified amount to the payees specified in
the applicable Funding Request as payment of such Transaction Expenses (which
may include reimbursement of such Transaction Expenses previously paid by the
Lessee), in each case from the funds provided by the Participants for such
Advance.

             Section
3.5      Allocation of
Commitments.
Schedule I hereto contains an allocation for each Participant of (i) the
amount of its Commitment representing its Tranche A Participation Interest
("Tranche A Participation Interest Commitment"), (ii) the
amount of its Commitment representing its Tranche B Participation Interest
("Tranche B Participation Interest Commitment"), and (iii) the
amount of its Commitment representing its Tranche C Equity Interest ("Tranche
C Equity Interest Commitment"). 
The Lessee, the Lessor, the Agent and the Participants have approved all
such allocations and percentages.  Schedule
I shall be amended as required to reflect changes in the allocations set
forth thereon due to the addition of additional Participants pursuant to Section
12.1.

             Section
3.6      Termination, Reduction or Extension of
Participants' Commitments.

                           (a)         The Lessor shall
have the right, upon
not less than five (5) 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; provided
that in the case of the occurrence and continuance of a Limited Event of
Default, such right may not be exercised on the basis of such Limited Event of
Default until from and after the second Land Interest Acquisition Date.

                           (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 a date following the Maturity Date then
in effect as specified in such Extension Request.  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 Y 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 the Tranche Y Participant and any 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:

 

                           (i)          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 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 and the Lessor, each as to itself, as
to the matters set forth in clause (x) above and from the Lessee as to
the matters set forth in clause (y) above; and

                           (ii)         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.

As
promptly as practicable following any Extension Effective Date, the Agent shall
deliver to the Lessee, the Lessor and each Participant a written notice (each,
an "Extension Notice" setting forth the Extended Maturity Date
then in effect.

                           (c)         The Lessor (after
consultation with,
and at the direction of, the Lessee) shall be permitted to replace any
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; 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 on or prior to the date of replacement, (iii) the
Lessee shall be liable to such Non-Consenting Participant 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) 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)        On the earlier of the Land Interest
Acquisition Date with respect to the Phase II Facility or the last day of the
Commitment Period, the Participants' Commitments 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.

             Section 3.7  
    Interest Rates, Yield and Payment Dates.

                           (a)         Each outstanding Advance
(other than
that portion of the Advance, if any, 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 (i) in respect of the Tranche A Participation Interests in any
Advance, a rate per annum equal to zero percent; (ii) in respect of the Tranche
B Participation Interests, a rate per annum for such Interest Period equal to
zero percent plus the Applicable Margin; and (iii) in respect of the
Tranche C Equity Interests in any Advance, a rate per annum (x) in the case of
any Eurodollar Rate Advance, the Eurodollar Rate two (2) Business Days prior to
the first day of such Interest Period, plus the Applicable Margin then in
effect and (y) in the case of any Alternate Base Rate Advance, at a rate per
annum equal to the Alternate Base Rate, in each case with respect to either clause
(x) or (y) as elected by Lessee in its Funding Request in respect of
the relevant Advance or in a notice delivered pursuant to this Section
3.7(a).  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 and this
Section 3.7(a), of the length of each Interest Period to be applicable
to any Tranche C Equity Interests accruing yield by reference to the Eurodollar
Rate, which election shall become effective three Business Days following the
date of such notice. Each of the Participants, Agent, Lessor and Lessee hereby
agree that Lessee shall have the right, by delivering a notice to Agent on or
before 12:00 noon (Chicago, Illinois time) on a Business Day, to elect irrevocably,
on not less than three nor more than five Business Days' written notice prior
to the last day of any then current Interest Period in the case of a notice
requesting a conversion of a Eurodollar Rate Advance into an Alternate Base
Rate Advance, or the continuation of a Eurodollar Rate Advance as such, that
all or any portion of the Tranche C Equity Interests in the Advances (in an
aggregate minimum amount of $5,000,000 and integral multiples of $100,000 in
excess thereof, in the case of the conversion of an Alternate Base Rate Advance
into a Eurodollar Rate Advance or the continuation of a Eurodollar Rate Advance
as an Advance of such type) (a) be converted into an Alternate Base Rate
Advance or a Eurodollar Rate Advance, or (b) be continued as a Eurodollar Rate
Advance.  Any conversion into, or
continuation of, a Eurodollar Rate Advance shall have Interest Periods (subject
to the limitations set forth in the definition thereof) of the length set forth
in such notice (in the absence of delivery of such notice at least three
Business Days before the last day of any then current Interest Period with
respect to any Eurodollar Rate Advance, Lessee shall be deemed to have elected
to continue the applicable Advance as a Eurodollar Rate Advance and the
Interest Period with respect thereto shall be one month).  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
by Lessee 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)         Except as
otherwise provided in paragraph
(d) of this Section 3.7, 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.

                           (d)        On each date which is
three Business
Days prior to any Scheduled Payment Date occurring prior to the initial Land
Interest Acquisition Date, the Lessee 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 the outstanding 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.  On each date prior to the initial Land
Interest Acquisition Date that any amount is payable under the Operative
Documents on account of (A) accrued interest and accrued yield on outstanding
Advances (to the extent provided in Section 3.7(d)), (B) fees pursuant
to Section 4, (C) Transaction Expenses of the Lessor, the Agent or any
Participant pursuant to Section 9, or (D) any other amounts required by
any provision of the Operative Documents to be capitalized prior to the initial
Land Interest Acquisition 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.

                           (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.  The Lessee shall also pledge Cash Collateral when required by the
Cash Collateral Agreement in connection with the capitalization of the
interest, yield and fees and amounts capitalized under Section 3.7(e).

             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 parties a statement showing the quotations used by the
Agent in determining any interest rate or yield rate pursuant to Section
3.8(a).

             Section
3.9      Pro Rata Treatment and Payments.

                           (a)         Each participation
in the Advances by
the Participants and each reduction of the Commitments of the Participants
shall be made pro rata among the Tranche A Participants, Tranche B Participants
and Tranche C Participants according to the respective 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 shall be made pro rata among such
Participants, without priority of any one such Participant over any others
within such Tranche, in the proportion that such Participant's Participant
Balance within such Tranche bears to the aggregate Participant Balances of all
Participants within such Tranche. 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 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 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 the Agent
and the Lessor hereby irrevocably instructs the Lessee, and the Lessee hereby
agrees, until otherwise notified by the Agent and except as otherwise expressly
provided in Section 3.22 hereof, that all payments to be made by the
Lessee to or for the benefit of the Lessor or the Agent pursuant to the Lease
or any of the other Operative Documents shall be made directly to the
Agent.  The Agent shall make
distributions of such payments, receipts and other consideration (and, if an
Account is used, from the Account) pursuant to the requirements of Sections 3.11
through 3.21 hereof.

             Section
3.11    Basic Rent. Each payment (or
portion thereof) of Basic Rent comprising interest or yield on the Advances
(and any payment of interest on overdue installments of such components of
Basic Rent) received by the Agent shall be distributed by the Agent (i) first,
to the Tranche A Participants and Tranche B Participants pro rata, and (ii)
second to the Tranche C Participants pro rata, in accordance with, and for
application to, the portion of their Participation Interests in such portion of
Basic Rent, as well as in any overdue interest due to such Participant (to the
extent permitted by applicable law).

sold following the occurrence of an Event of Default under Article XVII of the
Lease (in the case of any portion of such proceeds which, pursuant to Section

related portion of the Lease Balance owed by the Lessee to the Lessor in
respect of the Tranche Y Participant's Participant Balance without the
necessity of a cash payment being made by the Lessee to the Lessor or the Agent
or by the Lessor to the Agent, and (b) in the context of all distributions
required to be made by the Agent to the Participants or the Lessee pursuant to Sections

                           (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 the 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 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 Y 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, including, without limitation, 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 (other than by reason of the failure of the Lessor to maintain the
minimum equity required by EITF Issues 96-21 and 97-1), 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 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 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 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 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 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 Event of Default resulting in an acceleration of the Lessee's
obligation to purchase the Property under the Lease, except as otherwise expressly
limited in Section 17.2(h) of 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.

therefor or to make an Advance on any Funding Date following the Closing Date
and the obligation of each applicable Participant to purchase its Participation
Interest in, and to make available its related portion of, such Advance on any
such Funding Date are subject to satisfaction or waiver of the following
conditions precedent and to satisfaction on or before the relevant Land
Interest Acquisition Date as the case may be of the following additional
conditions precedent (it being understood that without limitation of the foregoing,
the Tranche Y Participant's obligation to make available to the Lessor its
portion of any Advance on any Funding Date following the Closing Date shall not
be subject to the conditions precedent set forth in this Section 6.3 to
the extent such conditions are actions required of the Lessee):

                           (a)         Representations
and Warranties.  On such date the representations and
warranties of the Lessee, the Lessor and each Participant contained herein and
in each of the other Operative Documents shall be true and correct as though
made on and as of such date, except to the extent such representations or
warranties relate solely to an earlier date, in which case such representations
and warranties shall have been true and correct on and as of such earlier date.

                          (b)        Performance of Covenants
 .  The parties hereto shall have performed
their respective agreements contained herein and in the other Operative
Documents to be performed by them on or prior to such date (but excluding in
the case of the Lessee any agreements contained in the Operative Documents
where the failure to perform such agreement would result in a Limited Default
or a Limited Event of Default, provided that if such a Limited Default
or Limited Event of Default exists, the provisions of Section 6.5 shall
apply).

                          (c)         Title
 .  Title to the Property shall conform to the
representations and warranties set forth in Sections 8.1(p), 8.2(c)

Other than a Limited Default or a Limited
Event of Default, there shall not have occurred and be continuing any Default
or Event of Default under any of the Operative Documents, and no Default or
Event of Default under any of the Operative Documents will have occurred after
giving effect to the acquisition of the relevant portion of the Property and/or
the making of the Advance requested by such Funding Request, as the case may
be, provided that if a Limited Default or a Limited Event of Default
exists or would have so occurred, the provisions of Section 6.5 shall
apply.

                           (e)         Cash Collateral
.  In the case of any Advance to be made on any
Funding Date following the Closing Date, the Lessee shall have deposited with
the Agent, in accordance with the Cash Collateral Agreement, Cash Collateral in
immediately available funds in an amount equal to the aggregate amount of the
Tranche B Participation Interests and Tranche C Participation Interests in such
Advance to be made on such Funding Date and otherwise as of such date shall
have made all deposits of Cash Collateral then required pursuant to the Cash
Collateral Agreement.

             Section
6.4      Satisfaction of Conditions
Precedent to Closing Date.  The parties hereto acknowledge and agree
that, with respect to the conditions precedent to the Closing Date set forth in
Section 6.1 hereof, the Lessor, the Agent and the Participants (other
than the Tranche Y Participant), by their execution and delivery of the
Operative Documents to be entered into by them on the Closing Date, and absent
fraud, gross negligence or willful misconduct on the part of the Lessee, shall
be deemed to have agreed that such conditions precedent were satisfied or
waived as of the Closing Date.

             Section
6.5      Effect of Failure to
Satisfy Conditions Precedent to Land Interest Acquisition Dates and Subsequent
Funding Dates.  The parties hereto acknowledge and agree
that in the event the conditions precedent set forth in Section 3.4, Section
6.2 or Section 6.3 to the occurrence of each Land Interest
Acquisition Date, the obligation of the Lessor to make an Advance to finance
Property Acquisition Costs on any Land Interest Acquisition Date and to acquire
any portion of the Property on any such date, and the obligation of each
Participant to purchase its Participation Interest in, and to make available to
the Lessor its related portion of, each such Advance on any such Land Interest
Acquisition Date (such conditions precedent being collectively referred to as
the "Acquisition/Funding Conditions"), are not met solely as a
result of the failure of the Lessee to satisfy a Limited Condition Precedent by
reason of (a) the occurrence of a Limited Default or a Limited Event of
Default, or (b) the existence or occurrence of an event, condition or
circumstance that has Material Adverse Effect but which does not also have an
Objective Material Adverse Effect, then, notwithstanding the failure of such
Limited Conditions Precedent to be satisfied, the Lessor shall be required to
acquire the relevant portion of the Property and make the related Advance to
finance Property Acquisition Costs or Transaction Expenses on the relevant Land
Interest Acquisition Date, and each Participant shall be obligated to purchase
its Participation Interest in, and make available to Lessor its related portion
of, such Advance on such date; provided that immediately following the
consummation of such purchase and the making of, and purchases of Participation
Interests in, such Advance, the Lessor, the Agent and the Participants
(excluding the Tranche Y Participant) shall be entitled in their sole
discretion to declare that a Limited Default or Limited Event of Default has
occurred and is continuing and to exercise their rights and remedies in respect
of such Limited Default or Limited Event of Default, subject only to the
limitations set forth in Section 17.2(h) of the Lease.  The parties hereto further acknowledge and
agree that in the event the Acquisition/Funding Conditions are otherwise not
satisfied, the Lessor shall have no obligation to acquire the relevant portion
of the Property and make the related Advance to finance Property Acquisition
Costs or Transaction Expenses on the relevant Land Interest Acquisition Date,
nor shall any Participant be obligated to purchase its Participation Interest
in, or make available to Lessor its related portion of, such Advance on such
date.

etc.  Each
Operative Document to which the Lessor is or will be a party has been, or on or
before the Closing Date (or the applicable Land Interest Acquisition Date, as

such Operative Document to which the Lessor is a party constitutes, or upon
execution and delivery will constitute, a legal, valid and binding obligation
enforceable against the Lessor in accordance with the terms thereof, except as
the same may be limited by insolvency, bankruptcy, reorganization or other laws
relating to or affecting creditors' rights or by general equitable principles.

                          (d)        Litigation

to its knowledge, threatened to which it is a party, before any Governmental
Authority that, if adversely determined, would materially and adversely affect

 .  Neither the Lessor nor any Person authorized
by the Lessor to act on its behalf has offered or sold any interest in the
Lease, or in any similar security relating to the Property, or in any security
the offering of which for the purposes of the Securities Act would be deemed to
be part of the same offering as the offering of the aforementioned securities
to, or solicited any offer to acquire any of the same from, any Person other
than the Agent and the Participants, and neither the Lessor nor any Person
authorized by the Lessor to act on its behalf will take any action which would
subject the issuance or sale of any interest in the Lease or the Property to
the provisions of Section 5 of the Securities Act or require the qualification
of any Operative Document under the Trust Indenture Act of 1939, as amended.

                           (h)        Chief Place of Business

inconsistent with, the provisions of Regulations T, U, or X of the Board.

                           (j)          
Investment Company Act.  The Lessor is not an "investment
company" or a company controlled by an "investment company"
within the meaning of the Investment Company Act.

                           (k)         No Plan Assets
 .  The Lessor is not acquiring its interests in
the Property with the 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).

             Section 7.2      Representations

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).  The advancing of any amount with
respect to its Participation Interest on any Funding Date shall constitute an
affirmation by the subject Participant of the preceding representation and
warranty as of such date.

                           (b)        Due Organization, etc
.  It is either (i) a duly organized and

Operative Documents to which it is a party.

                           (c)         Authorization;
No Conflict.  The execution, delivery and performance of
each Operative Document to which it is or will be a party has been duly
authorized by all necessary action on its part and neither the execution and

Enforceability,
etc.  Each
Operative Document to which it is a party has been, or on or before the Closing
Date will be, duly executed and delivered by it and each such Operative
Document to which it is a party constitutes, or upon execution and delivery

party.

                           (f)         Investment
 .  The Participation Interest being acquired by
such Participant is being acquired by such Participant for investment and not
with a view to the resale or distribution of such interest or any part thereof,
but without prejudice, however, to the right of such Participant at all times
to sell or otherwise dispose of all or any part of such interest under a
registration available under the Securities Act or under an exemption from such
registration available under the Securities Act, it being understood that the
disposition of the Participation Interest to be purchased by such Participant

any Person.

                           (h)        No Registration
 .  Such Participant understands and
acknowledges that the Participation Interests have not been and will not be
registered under the Securities Act in reliance upon the exemption provided in
Section 4(2) of the Securities Act or any other applicable exemption, that
Participation Interests have not and will not be registered or qualified under
the securities or "blue sky" laws of any jurisdiction, that the
Participation Interests may be resold or otherwise transferred only if so

risks of its investment in the Participation Interests and is able to bear the
economic risk of such investment.  Such

SECTION 8

REPRESENTATIONS OF THE LESSEE

             Section
8.1      Representations of the
Lessee. The Lessee represents
and warrants to each of the other parties hereto (other than the Tranche Y
Participant) that:

                           (a)         Organization;
Powers; Qualification.
Each of the Lessee and its Restricted Subsidiaries (a) is a corporation or
other entity duly organized, validly existing and in good standing under the
laws of its respective jurisdiction of organization, (b) has all requisite
power and authority to own, lease and operate its properties, to carry on its
business, to enter into the Operative Documents to which it is a party and to
carry out the transactions contemplated hereby and thereby, and (c) is
qualified or licensed to do business and is in good standing in each
jurisdiction in which the failure to be so qualified or licensed or in good
standing has not had, and could not be reasonably expected to have, an
Objective Material Adverse Effect.  The
Lessee's chief place of business is located in Santa Clara County, California.

                           (b)        Authorization of Operative
Documents;
No Conflict.  The execution, delivery
and performance by the Lessee of the Operative Documents to which it is or will
be a party have been or as of the relevant date of execution and delivery
thereof will be duly authorized by all necessary corporate action on the part
of the Lessee.  The execution, delivery
and performance by the Lessee of the Operative Documents to which it is or will
be a party and the consummation by the Lessee of the transactions contemplated
by the Operative Documents do not and will not (i) violate any material provision
of any law or any governmental rule or regulation applicable to the Lessee, any
of the certificate of incorporation or bylaws of the Lessee, or any order,
judgment or decree of any court or other agency of government binding on the
Lessee or the Property or any portion thereof; (ii) conflict with, result in a
breach or an acceleration of or entitle any other Person to accelerate (with
due notice or lapse of time or both) any indenture, loan agreement, other
agreement for borrowed money or other agreement or contractual arrangement of
the Lessee required by Regulation S–K to be made part of the Lessee's
filings with the SEC pursuant to the Exchange Act; (iii) result in or require
the creation or imposition of any Lien (or the obligation to create or impose
any Lien) upon any of the properties or assets of the Lessee (other than any
Liens created under any of the Operative Documents and other than Permitted
Liens); or (iv) require any approval of stockholders or any approval or consent
of any Person under any indenture, loan agreement, other agreement for borrowed
money or other agreement or contractual arrangement of the Lessee required by
Regulation S–K to be made part of the Lessee's filings with the SEC
pursuant to the Exchange Act, 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 Lessee of the Operative Documents to which it is or will be a party and the
consummation by the Lessee of the transactions contemplated by the Operative
Documents do not and will not require any Governmental Action by any
Governmental Authority except for filings and recordings of the Operative
Documents (as listed in Section 8.2(f) hereof with respect to each
portion of the Property) the appropriate Governmental Authorities, all of which
will have been completed on or prior to the applicable Land Interest
Acquisition Date.

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

                           (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 SEC 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 Lessee
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 Lessee 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 Lessee 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
individually or in the aggregate, (i) that 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 an Objective Material Adverse Effect.  Neither the Lessee nor any of its Restricted
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 governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, that, individually or in the
aggregate, could reasonably be expected to have an Objective Material Adverse
Effect.

                           (h)        Payment of Taxes
 .  All federal and all material state, local
and foreign tax returns and reports of the Lessee and its Restricted
Subsidiaries required to be filed by any of them have been filed where the
failure to file would have an Objective 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 Lessee and its Restricted 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 Lessee knows of no material proposed tax adjustment against the
Lessee or any of its Subsidiaries which is not being actively contested by the
Lessee 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 Lessee nor any of its Restricted
Subsidiaries is in violation of or in default with respect to (i) any provision
of any Applicable Law, other than violations or defaults which could not
reasonably be expected to have an Objective 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,
other than violations or defaults which could not reasonably be expected to
have an Objective Material Adverse Effect.

                          (j)          
Governmental
Regulation. The Lessee is not subject to regulation under the Public Utility
Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce
Act, or, any state public utilities code or under any other federal or state
statute or regulation which may limit its ability to incur Indebtedness or to
grant Liens on any of its property or assets, or which may otherwise render all
or any portion of the obligations of the Lessee to the Lessor, the Agent or the
Participants under the Operative Documents unenforceable.  As of the date hereof the Lessee is subject
to regulation under the Investment Company Act of 1940, as amended, provided
that the SEC has issued an exemption order in favor of the Lessee with respect
to such Act, and provided further that neither such status of the
Lessee with respect to such Act, nor the terms of such exemption order, limits
the Lessee's ability to incur Indebtedness or otherwise renders all or any
portion of the obligations of the Lessee to the Lessor, the Agent or the
Participants under the Operative Documents unenforceable.

                           (k)         Employee
Benefit Plans.

                           (i)          Neither the
Lessee nor any ERISA
Affiliate maintains or contributes to, or has ever maintained a Pension Plan.
Neither the Lessee 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 an Objective
Material Adverse Effect.

                           (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 Lessee or any
ERISA Affiliate of any material liability, fine or penalty.  Each Employee Benefit Plan, related trust
agreement, arrangement and commitment of the Lessee 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 Lessee, threatened, claim or
suit.  Neither the Lessee 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 Lessee nor
any ERISA
Affiliate contributes to or has ever contributed to any Multiemployer Plan.

                           (iv)       If the Lessee 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
an Objective Material Adverse Effect, then the Lessee shall promptly provide a
written notice thereof and a statement affirming that no Objective Material
Adverse Effect could reasonably be expected to occur as a result thereof.

                          (l)          
Licenses, Permits, etc.  The
Lessee and its Subsidiaries own or possess all licenses, permits, franchises,
authorizations, copyrights, service marks, trademarks and trade names or rights
thereto, and to their knowledge possess all patents, that individually or in
the aggregate, are material to the conduct of its business and, in the case of
patents, excluding those the failure of which to own or possess would not
reasonably be expected to result in an Objective Material Adverse Effect.  To the best knowledge of the Lessee, no such
license, permit, franchise, authorization, patent, copyright, service mark,
trademark or trade name, and no product of the Lessee or any of its Restricted
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, except for such infringement as
would not reasonably be expected to result in an Objective Material Adverse
Effect.  To the best knowledge of the
Lessee, there is no material violation by any Person of any right of the Lessee
or any of its Subsidiaries with respect to any patent, copyright, service mark,
trademark, trade name or other right owned or used by the Lessee or any of its
Subsidiaries other than violations which would not reasonably be expected to
have an Objective Material Adverse Effect.

                           (m)        Subsidiaries. 
 Schedule III identifies each
Subsidiary of the Lessee as of the date hereof, 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 Lessee
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 outstanding.

                           (n)        Offer of Securities, et
c.  Neither the Lessee nor any Person authorized
to act on its behalf has, directly or indirectly, offered or will offer any
interest in the Property or any portion thereof 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 Lessee
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 Lessee pursuant to the Operative Documents 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 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 to the Lessee that,
individually or in the aggregate, could reasonably be expected to result in
either an Objective Material Adverse Effect or 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.

                          (p)        Intentionally
Omitted.

received any notice
of violation, alleged violation, non-compliance, liability or potential
liability regarding environmental matters or compliance with Environmental Laws
with regard to the Property, nor does the Lessee have knowledge or reason to

Concern are
not being transported or disposed of from the Property by Lessee or any of its
Affiliates in violation of, or in a manner or to a location which could
reasonably be expected to give rise to material liability under, any
Environmental Law, nor are any Materials of Environmental Concern being
generated, treated, stored or disposed of at, on or under any of the Property
in violation of, or in a manner that could reasonably be expected to give rise
to material liability under, any applicable Environmental Law.

                           (v)        There are no judicial
proceedings or
governmental or administrative actions pending under any Environmental Law in
which the Lessee or any of its Subsidiaries is named as a party with respect to
the Property nor are there any consent decrees or other decrees, consent
orders, administrative orders or other orders, or any administrative or
judicial requirements outstanding under any Environmental Law with respect to
the Property.

                           (vi)       There has been no release of
Materials of

 .  The Lessee is solvent and has assets having
a value both at fair value and at present fair saleable value at least equal to
the amount of its liabilities.

             Section 8.2      Representations
of the Lessee with Respect to the Property. The Lessee hereby
represents and warrants to each of the other parties hereto (other than the
Tranche Y Participant), on the Closing Date and on each other date on which
representations and warranties of the Lessee are made or deemed made pursuant
to the Operative Documents, as follows:

                           (a)         Representations
.  The representations and warranties of the
Lessee set forth in the Operative Documents to which it is a party are true and
correct on and as of such date, except to the extent such representations or
warranties relate solely to an earlier date, in which case such representations
and warranties shall have been true and correct on and as of such earlier
date.  The Lessee is in compliance with
its obligations under the Operative Documents to which it is a party and there
exists no Default or Event of Default.

                           (b)        Property. 
The Property consists of the Phase I Land
Interest on which the Phase I Improvements (which are of the type described in Recital
A to this Agreement) will have been constructed as of the initial Land
Interest Acquisition Date and, from and after the Land Interest Acquisition Date
in respect thereof, the Phase II Land Interest on which the Phase II
Improvements (which will be of the type described in Recital A to this
Agreement) will have been constructed as of such Land Interest Acquisition
Date. The Property is located in Sunnyvale, California.  The Property does, and as improved in
accordance with the applicable Plans and Specifications will as of the
applicable Land Interest Acquisition Date, and the use thereof by the Lessee,
its Subsidiaries and their respective agents, assignees, employees, invitees,
lessees, licensees, contractors and tenants does and will comply in all
material respects with all Requirements of Law (including, without limitation,
Title III of the Americans with Disabilities Act, all zoning and land use laws,
all Environmental Laws and all building, planning, zoning and fire codes),
except for such Requirements of Law as the Lessee shall be contesting in good
faith by appropriate proceedings and in accordance with the applicable
provisions of the Lease, and complies with all Insurance Requirements.  The applicable Plans and Specifications have
been prepared in all material respects in accordance with applicable
Requirements of Law (including, without limitation, Title III of the Americans
with Disabilities Act, all zoning and land use laws, all Environmental Laws and
all building, planning, zoning and fire codes) and neither the Phase I
Improvements nor, upon completion thereof in accordance with the applicable
Plans and Specifications, the Phase II Improvements, encroach in any manner
onto any adjoining land (except as permitted by express written easements or as
insured by appropriate title insurance). 
Each of the Phase I Improvements, and upon completion thereof in accordance
with the related Plans and Specifications, the Phase II Improvements (including
in each case, without limitation, structural members, the plumbing, heating,
air conditioning and electrical systems of any such Improvements), and all
water, sewer, electric, gas, telephone and drainage facilities, have been or
will be completed in a workmanlike manner and in accordance with the applicable
Plans and Specifications and will be fit for use as first class facilities of
the type described in Recital A to this Agreement, and all other
utilities required to adequately service any such Improvements for their
intended use are or will be available and "tapped on" and hooked up
pursuant to adequate permits (including any that may be required under
applicable Environmental Laws).  There
is no action, suit or proceeding (including any proceeding in condemnation or
eminent domain or under any Environmental Law) pending or, to the best of the
Lessee's knowledge, threatened with respect to the Lessee, its Affiliates or
the Property which materially adversely affects the title to, or the use,
operation or value of, the Property or any portion thereof.  Except as may be disclosed to the Lessor and
the Agent in writing in accordance with Section 15.1(c) of the Lease, no fire
or other casualty with respect to the Property or any portion thereof has
occurred.  The Property has available
(or will have available by the applicable Land Interest Acquisition Date) all
material services of public facilities and other utilities necessary for use
and operation of such facilities and the other Improvements for their primary
intended purposes, including, without limitation, adequate water, gas and
electrical supply, storm and sanitary sewerage facilities, telephone, other
required public utilities and means of access to such facilities from publicly
dedicated streets and public highways for pedestrians and motor vehicles.  All utilities serving the Property, or
proposed to serve the Property in accordance with the applicable Plans and Specifications,
are (or will be) located in, and vehicular access to each of the Phase I
Improvements and the Phase II Improvements on the Property is (or will be)
provided by, either public rights-of-way abutting such portion of the Property
or Appurtenant Rights.  All material
licenses, approvals, authorizations, consents, permits (including, without
limitation, building, and environmental permits, licenses, approvals,
authorizations and consents), easements and rights–of–way,
including proof and dedication, required for the use and operation of any of
the Improvements in accordance with the applicable Plans and Specifications
have either been obtained from the appropriate Governmental Authorities having
jurisdiction or from private parties, as the case may be, or will be obtained
from the appropriate Governmental Authorities having jurisdiction or from
private parties, as the case may be, prior to commencing any such use and
operation, and will in each case be maintained by the Lessee during the periods
for which they are required by Applicable Law or such Governmental Authorities.

                           (c)         Title.  Each Deed
providing for the acquisition of a portion of the
Property is sufficient to convey title to such portion of the Property in fee
simple, subject only to Permitted Exceptions. 
Upon conveyance of the relevant Deed on the relevant Land Interest
Acquisition Date, the Lessor will own fee simple title to the relevant portion
of the Property and the applicable Improvements thereon, subject to Permitted
Exceptions, and will have the right to grant a Mortgage on such portion of the
Property.

                           (d)        Insurance. 
The Lessee has obtained insurance coverage
covering the Property which meets the requirements of Article XIV of the Lease,
and such coverage is in full force and effect.

                           (e)         Lease. 
 (i) Upon the execution and delivery of each Lease Supplement, the
Lessee will have unconditionally accepted the portion of the Property covered
thereby and will be bound by the terms of such Lease Supplement and, upon the
applicable Lease Commencement Date will have a valid leasehold interest in the
related portion of the Property, subject only to the Permitted Exceptions; (ii)
from and after the applicable Lease Commencement Date, the Lessee's obligation
to pay Rent will be an independent covenant and no right of deduction or offset
will exist with respect to any Rent or other sums payable under the Lease; and
(iii) from and after the applicable Lease Commencement Date, no Rent under the
Lease will have been prepaid and the Lessee will have no right to prepay the
Rent, except as specifically set forth therein.

                           (f)         Protection of
Interests. (i) On
each Land Interest Acquisition Date, the applicable Lease Supplement, the
Assignment of Lease, the Consent to Assignment and the applicable Mortgage are
each in a form sufficient, and have been or will be recorded with the Office of
the Recorder of Santa Clara County, California, which is the only recording
office necessary to grant perfected first priority liens on the applicable
portion of the Property covered thereby to the Agent or the Lessor, as the case
may be, (ii) the Agent Financing Statements are each in a form sufficient, and
have been delivered to the title company for filing or will be filed with the
Secretary of State of the State of California and the Office of the Recorder of
Santa Clara County, California, which are all filing offices necessary to
create a valid and perfected first priority security interest in the Lessor's
interest in the relevant Improvements; and (iii) the Lessor Financing
Statements are each in a form sufficient, and have been delivered to the title
company for filing or will be filed with the Secretary of State of the State of
California and the Office of the Recorder of Santa Clara County, California,
which are all filing offices necessary to perfect the Lessor's interest under
the Lease to the extent the Lease is a security agreement.

                           (g)        Flood Hazard Areas.  No
portion of the Property is located in an
area identified as a special flood hazard area by the Federal Emergency
Management Agency or other applicable agency, or if any portion of the Property
is located in an area identified as a special flood hazard area by the Federal
Emergency Management Agency or other applicable agency, then flood insurance
has been obtained for the Property or such portion thereof in accordance with
Section 14.3 of the Lease and in accordance with the National Flood Insurance
Act of 1968, as amended.

                           (h)        Conditions Precedent
 .  All conditions precedent (other than the
Limited Conditions Precedent, provided that if a Limited Condition
Precedent has not been satisfied, the provisions of Section 6.5 shall
apply) contained in this Agreement and in the other Operative Documents
relating to the acquisition and, upon the applicable Lease Commencement Date,
leasing of the applicable portion of the Property by the Lessor have been
satisfied in full.

Lessee With Respect to Each Advance.  The Lessee hereby represents and warrants as

.  The representations and warranties of the
Lessee set forth in the Operative Documents to which it is a party (including
the representations and warranties set forth in Sections 8.1 and 8.2)
are true and correct on and as of such Funding Date, except to the extent such
representations or warranties relate solely to an earlier date, in which case
such representations and warranties shall have been true and correct on and as
of such earlier date.  The Lessee is in
compliance with its obligations under the Operative Documents and there exists
no Default or Event of Default (other than a Limited Default or a Limited Event
of Default, provided that if a Limited Default or a Limited Event of
Default exists, the provisions of Section 6.5 shall apply).  No Default or Event of Default (other than a
Limited Default or a Limited Event of Default, provided that if a
Limited Default or a Limited Event of Default exists, the provisions of Section
6.5 shall apply) will occur as a result of, or after giving effect to, the
Advance requested by the Acquisition Request or the Funding Request on such
date.

                           (b)        No Liens. 
There are no Liens against the Property
other than Permitted Exceptions.  The
Participation Interests funding such Advance are secured by the Lien of the
Mortgage.

                           (c)         Advance.  The
amount of the Advance requested
represents amounts owing in respect of the acquisition price of the applicable
portion of the Property and related Transaction Expenses or amounts paid by the
Lessee to third parties in respect of Transaction Expenses for which the Lessee
has not previously been reimbursed by an Advance.  The conditions precedent on the part of the Lessee to such
Advance and the related remittances by the Participants with respect thereto set
forth in Section 6 have been satisfied (other than the Limited
Conditions Precedent, provided that if a Limited Condition Precedent has
not been satisfied, the provisions of Section 6.5 shall apply).

                           (d)        Insurance.

Restricted Subsidiaries to perform each of the following covenants:

                           (i)          General Business
Operations.  Each of the Lessee and its Restricted
Subsidiaries shall (i) preserve and maintain its corporate existence and all of
its rights, privileges and franchises reasonably necessary to the conduct of
its business, and (ii) conduct its business activities in compliance with all applicable
laws and governmental rules and regulations, and all indentures, loan
agreements or other agreements for borrowed money or other material agreements
or contractual arrangements applicable to such entity or its property or
assets, the violation of which is reasonably likely to have a Material Adverse
Effect; provided, however, that the Lessee and its Subsidiaries
may dissolve, liquidate or dispose of any of its Subsidiaries if such
dissolution, liquidation or disposition is not reasonably likely to have a
Material Adverse Effect.  The Lessee
shall maintain its chief executive office and principal place of business in
the United States and shall not relocate its chief executive office of
principal place of business outside of the State of California except upon not
less than thirty (30) days prior written notice to the Agent.

claims (including claims for labor, services, materials and supplies) for sums
that have become due and payable and that by law have or may become a Lien upon
any of its properties or assets, prior to the time when any penalty or fine
shall be incurred with respect thereto; provided, no such charge or
claim need be paid if it is being contested in good faith by appropriate
proceedings promptly instituted and diligently conducted and for which
appropriate reserves as required by GAAP are maintained.  The Lessee will not file or consent to the
filing of any consolidated income tax return with any Person (other than its
Subsidiaries).

result in, Environmental Claims that could reasonably be expected to have,
individually or in the aggregate, an Objective Material Adverse Effect or (B)
affect the ability of the Lessee or any of its Restricted Subsidiaries to

The Lessee will comply, and shall cause each
of its Restricted 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, an Objective Material Adverse Effect.

within the meaning of Section 3(2) of ERISA, (ii) take any action which will
result in the partial or complete withdrawal, within the meanings of Section
4203 and 4205 of ERISA, from a Multiemployer Plan, (iii) engage or permit any
Person to engage in any transaction prohibited by Section 406 of ERISA or
Section 4975 of the Code involving any Employee Benefit Plan or Multiemployer
Plan which would subject either the Lessee or any ERISA Affiliate to any tax,
penalty or other liability including a liability to indemnify, (iv) incur or
allow to exist any accumulated funding deficiency (within the meaning of
Section 412 of the Code or Section 302 of ERISA), (v) fail to make full payment
when due of all amounts due as contributions to any Employee Benefit Plan or

of the Code or Part 6 of Title I(B) of ERISA, or (vii) adopt any amendment to
any Employee Benefit Plan which would require the posting of security pursuant
to Section 401(a)(29) of the  Code,
which, in the case of clauses (i) through (vii) above, singly or
cumulatively, could reasonably be expected to have an Objective Material
Adverse Effect.

             Section
10.2    The Lessee's
Financial Covenants. So long as this
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 Lessee
will comply and will cause compliance, on a consolidated basis with the
following financial covenants (for illustration purposes, a calculation of such
financial covenants as of December 31, 2000, is set forth on Exhibit 10.2
("Financial Covenant Worksheet") and the parties hereto agree
that such covenants shall be calculated in accordance with the methodology
demonstrated on the Financial Covenant Worksheet):

                           (a)         Maximum
Leverage Ratio.  The Lessee shall not permit the Leverage
Ratio to be greater than 1.25 to 1.00 as of the last day of any Fiscal Quarter
for the four Fiscal Quarter period then ended.

                           (b)        Quick Ratio. 
 The Lessee shall not permit its Quick Ratio
for any Fiscal Quarter to be less than 2.00 to 1.00.

                           (c)         Fixed Charge
Coverage Ratio.  The Lessee shall not permit its Fixed Charge
Coverage Ratio to be less than 2.50 to 1.00 as of the last day of any Fiscal
Quarter for the four Fiscal Quarter period then ended.

                           (d)        Consolidated Net Worth
.  The Lessee shall not permit the sum of (x)
its Consolidated Net Worth on the last day of any Fiscal Quarter (such date to
be referred to herein as a "determination date"), plus
(y) with respect to each Fiscal Quarter after the base date and through
the determination date in which Lessee had a quarterly loss, all charges taken
for the purchase of in-process research and development and amortization
expense, in each case to the extent deducted in determining the Lessee's
consolidated quarterly net income for each such Fiscal Quarter, plus (z) the
value of Lessee's treasury stock, calculated at the fair market value of such
stock as of the date such stock was repurchased by the Lessee, to be less than
the sum on such determination date of the following:

                           (i)          eighty-five
percent (85%) of the
Consolidated Net Worth of the Lessee and its Subsidiaries as of December 31,
1999 (the "base date");

plus

                           (ii)         fifty percent
(50%) of the sum of the
Lessee's consolidated quarterly net income (but with no deduction of any
quarterly losses unless such negative quarterly consolidated net income was
caused solely by charges taken for the purchase of in-process research and
development and amortization expense, in which case such charges shall be
excluded in the determination of such quarterly consolidated net income) by the
Lessee and its Subsidiaries for each Fiscal Quarter after the base date through
and including the Fiscal Quarter ending on the determination date;

plus

                           (iii)        one hundred percent
(100%) of the net
proceeds (including the fair market value of property other than cash, as
determined in good faith by the Lessee's board of directors) of all Equity
Securities issued by the Lessee and its Subsidiaries during the period
commencing on the base date and ending on the determination date, including any
Equity Securities issued upon the conversion or exchange of any Indebtedness of
the Lessee after the latest Fiscal Quarter end (the net proceeds of which for
purposes of this clause (iii) shall be deemed to equal the aggregate
market value of the Equity Securities so issued upon such conversion or
exchange), but excluding any such net proceeds of any Equity Securities (x)
issued and sold to Lessee or any of its Subsidiaries, or (y) which are required
to be redeemed, or which are redeemable at the option of the holder thereof, if
certain events or conditions exist or otherwise.

             Section
10.3    Cooperation with
the Lessee.  The
Lessor, the Participants and the Agent shall, to the extent reasonably
requested by the Lessee (but without assuming additional liabilities, duties or
other obligations on account thereof), at the Lessee's expense, cooperate with
the Lessee in connection with its covenants contained herein including, without
limitation, at any time and from time to time, upon the request of the Lessee,
to promptly and duly execute and deliver any and all such further instruments,
documents and financing statements (and continuation statements related
thereto) as the Lessee may reasonably request in order to perform such covenants.

             Section
10.4    Covenants of the
Lessor.  The Lessor hereby agrees that so long as
this Participation Agreement is in effect:

                           (a)         Discharge of Lien
s.  The Lessor will not create or permit to
exist at any time, and will, at its own cost and expense, promptly take such
action as may be necessary duly to discharge, or to cause to be discharged, all
Lessor Liens on the Property attributable to it;  provided, however, that the Lessor shall not be
required to so discharge any such Lessor Lien while the same is being contested
in good faith by appropriate proceedings diligently prosecuted so long as such
proceedings shall not involve any material danger of impairment of the Liens of
the Lease or the Security Documents or of the sale, forfeiture or loss of, and
shall not interfere with the use or disposition of, the Property or title
thereto or any interest therein or the payment of Rent; provided, further,
that in the event the Lessee purchases the Property the Lessor shall discharge
all such Lessor Liens on or prior to the date on which the purchase is
effective under the Lease.

                           (b)        Change of Chief Place
of Business.  The Lessor shall give prompt notice to the
Lessee and the Agent if the Lessor's chief place of business or chief executive
office, or the office where the records concerning the accounts or contract
rights relating to the Property are kept, shall cease to be located at 135
South LaSalle Street, Chicago, Illinois 60603, or if it shall change its name,
identity or corporate structure.

                           (c)         Use of Proceeds
.  The proceeds of the purchase of the
Participation Interests shall be applied by the Lessor solely in accordance
with the provisions of the Operative Documents.

termination, amendment,
supplement, waiver or modification shall without written agreement or consent
of each Participant (other than the Tranche Y Participant except with respect
to clause (vii) below):

                           (i)          modify any
of the provisions of this Section
11, change the definition of "Required Participants" or
modify or waive any provision of an Operative Document requiring action by the
foregoing;

                           (ii)         amend, modify,

payable to it);

                           (iv)       modify, postpone, reduce or
forgive, in
whole or in part, any payment of Rent (other than pursuant to the terms of any
Operative Document), any payment in respect of its Participation Interest, or
any payment of Asset Termination Value, Commitment Fee, Residual Value
Guarantee Amount, amounts due pursuant to Section 22.2 of the Lease, or
interest or yield or, subject to clause (iii) above, any other amount

                           (v)        consent to any

obligations in respect of the payments of Rent and any Asset Termination Value
or changing the absolute and unconditional character of such obligation;

                           (vi)       except as authorized by the
Operative
Documents, release the Lessor's interest in all or a substantial part of the
Property; or

                           (vii)      increase the amount of the
Commitment of
such Participant; and

             (b)        no
other termination, amendment, supplement, waiver or modification shall, without
the written agreement or consent of the Lessor and the Required Participants,
be made to the Lease or Section 6 of this Participation Agreement or the
definition of "Event of Default".

             Section 11.2    Actions
by Participants.  Notwithstanding the foregoing, Defaulting
Participants shall have no voting or consent rights under this Section 11.2
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.  Furthermore, 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.

             Section 11.3    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 or to the Agent on behalf of 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 in respect of such Participant's Participation Interest.

             Section 11.4    
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 11.4 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
11.4 to indemnify the Lessor (i) 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 (ii)
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
11.5    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 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 (w) any Participant (other than the Tranche Y
Participant) may pledge its interest without the consent of the Agent or the
Lessee to any Federal Reserve Bank, (x) without the prior written consent of
the Agent, any Participant (other than the Tranche Y Participant) may transfer
all or any portion of its interest to any affiliate of such Participant or to
any other existing Participant, (y) the Tranche Y 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 , and (z) no Tranche C
Participant may assign, convey or otherwise transfer any portion of its right,
title or interest in, to or under its Tranche C Equity Interest without the
prior written consent of the Agent and unless the proposed transferee delivers
to the Agent and the Lessee the certificate required by Section 12.1(d);
provided, further, that in the case of any transfer (other than a
transfer to an affiliate of the relevant Participant pursuant to clause (x)
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.

                           (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 K ("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 L ("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) (i) confirming the
accuracy of the representations and warranties set forth in Section 7
with respect to such Person (other than as such representation or warranty
relates to the execution and delivery of Operative Documents), (ii)
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 , and (iii) in
the case of a transferee of a Tranche C Equity Interest only, representing that
no portion of the Tranche C Equity Interest to be funded or acquired by such
Person has been or will thereafter be borrowed by such Person such that
recourse in respect of such indebtedness is limited to such Person's interest
in the Lessor (if applicable) or to collateral with an aggregate value less
than the amount of such indebtedness, and that such Person has not obtained and
will not obtain residual value insurance, or a comparable guarantee, with
respect to its Tranche C Equity Interest.

                           (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.

                           (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 Y 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.

             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 13

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

described in Sections 13.2, 13.3, 13.6, 13.7, 13.8
and 13.10 or (5) with respect to any Indemnitee, any Claims arising from
the breach by such Indemnitee of its express obligations under any Operative
Document, other than any such breach caused by or attributable to the Lessee's
actions or failure to act.  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 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, the Required Participants and the Lessee and 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 (but excluding any decline in
the Fair Market Sales Value of the Property resulting from or attributable to
any failure of Lockheed to pay or perform its express obligations under the
Lockheed Indemnification Agreements); 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 A 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 or any portion thereof, 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 relevant Land Interest Acquisition Date and were disclosed
in the relevant title report delivered in respect of such portion of the
Property 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, penalties, charges, administrative and judicial proceedings
(including informal proceedings) and orders, judgments, remedial action,
requirements, enforcement actions of any kind, and all reasonable and
documented costs and expenses incurred in connection therewith (including but
not limited to reasonable and documented attorneys' and/or paralegals' fees and
expenses), including, but not limited to, all costs incurred in connection with
any investigation or monitoring of site conditions or any clean–up,
remedial, removal or restoration work by any 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 on or undertaken on or off the Property, and
whether by the Lessee, the Lessor, the Existing Owner, any predecessor in title
or any sublessee or any employees, agents, contractors or subcontractors of the
Lessee, the Lessor, 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 caused or
contributed to such Claim), (2) any Imposition or other claims for Taxes of the
type(s) described in Section 13.5, (3) any Claims of the type(s)
described in Sections 13.2, 13.6, 13.7, 13.8 and 13.10
or (4) any Claim in respect of the Pre-Existing Environmental Conditions, provided
that clause (4) shall not be deemed or construed so as to limit Lessor's
rights and remedies under the Lockheed Indemnification Agreements.  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 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 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
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 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 file
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.

                           (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.

                           (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 thirty
(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 two (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
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:

                           (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; and

                           (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.

                           (h)        Limitation on Tax
Indemnification.  Subject to Section 13.10, 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 Impositions
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 4,
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 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 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 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 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), 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.

             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, the 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 14

THE AGENT

             Section 14.1    Appointmen
t. 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, or the Lessee 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 or the Lessee 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 or the Lessee.

             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 or the Lessee describing
such Default or Event of Default and stating that such notice is a "notice
of default".  In the event that the
Agent receives such a notice, the Agent shall give notice thereof to the other
parties hereto.  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
or the Lessee, 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 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 and the Lessee.  Except for
notices, reports and other documents expressly 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 or the Lessee which may
come into the possession of the Agent or any of its officers, directors,
employees, agents, attorneys–in–fact or affiliates.

             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 or the Lessee 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 thirty
(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 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 thirty (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

15.1    Survival of

survive the execution and delivery of this Participation Agreement, the
transfer of the Property to the Lessor, any disposition of any interest of the
Lessor in the Property or any portion thereof, 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

representation.

Agreement are intended for the benefit of any Person except the parties

Documents without the prior written consent of the Lessor, the Agent and the
Participants.

or render unenforceable such provision in any other jurisdiction.

forum.

MASTER LEASE

             THIS MASTER LEASE (as amended,
supplemented or otherwise modified from time to time, this "Lease"),
dated as of March 16, 2001, is by and between LEASE PLAN NORTH AMERICA, INC.,
an Illinois corporation, having its principal office at 135 S. LaSalle Street
Chicago, Illinois 60603, as the lessor (together with its permitted successors
and assigns, the "Lessor") and YAHOO! INC., a Delaware
corporation, having its principal office at 3420 Central Expressway, Santa
Clara, California 95051, as the lessee (the "Lessee").

W I T N E S S E T H:

             A.         WHEREAS,
the Lessor will purchase the Phase I Facility on the Land Interest Acquisition
Date therefor and will purchase the Phase II Facility on the Land Interest
Acquisition Date therefor, and each of the Phase I Facility and the Phase II
Facility will be leased to the Lessee subject to the terms of this Lease from
and after the relevant Land Interest Acquisition Date; and

             B.          WHEREAS,
on the applicable Lease Term Commencement Date, the Lessor desires to lease to
the Lessee and the Lessee desires to lease from the Lessor, the relevant
portion of the Property pursuant to this Lease.

             NOW, THEREFORE, in consideration of
the foregoing, and of other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

ARTICLE I.

             1.1        Definitions;
Interpretation. 
Capitalized terms used
but not otherwise defined in this Lease have the respective meanings specified
in Appendix 1 to this Lease; and the rules of interpretation set forth
in Appendix 1 to this Lease shall apply to this Lease.

ARTICLE
II.

             2.1        Acceptance and Lease of Property.  Effective as of the Closing Date, the Lessor,
subject to the satisfaction or waiver of the applicable conditions set forth in
Section 6 of the Participation Agreement, hereby agrees to acquire the Phase I
Facility on the initial Land Interest Acquisition Date pursuant to the terms of
the Participation Agreement, and to lease to the Lessee hereunder for the Term
(as defined in Section 2.3), the Lessor's interest in such Phase I
Facility and, subject to satisfaction or waiver of the applicable conditions
set forth in Section 6 of the Participation Agreement, effective as of the Land
Interest Acquisition Date in respect of the Phase II Facility, the Phase II
Facility, and the Lessee hereby agrees, expressly for the direct benefit of the
Lessor, to lease commencing on the applicable Lease Commencement Date from the
Lessor for the Term, the Lessor's interest in each such portion of the Property
to be delivered on the applicable Land Interest Acquisition Date and any
Improvements thereon pursuant to this Lease or the Participation Agreement.

             2.2        Acceptance Procedure;
Appointment as Agent.  The Lessor hereby authorizes one or more
employees of the Lessee, to be designated by the Lessee, as the authorized
representative or representatives of the Lessor to accept delivery on behalf of
the Lessor of the relevant portion of the Property identified on the applicable
Acquisition Request.  The Lessee hereby
agrees that such acceptance of delivery by such authorized representative or
representatives and the execution and delivery by the Lessee on each Land Interest
Acquisition Date of a Lease Supplement in the form of Exhibit A hereto
with respect to the applicable portion of the Property (appropriately
completed) shall, without further act, constitute the irrevocable acceptance by
the Lessee of the portion of the Property which is the subject thereof for all
purposes of this Lease and the other Operative Documents on the terms set forth
therein and herein. In addition, the Lessor hereby irrevocably designates and
appoints the Lessee as its agent for the purpose of supervising and monitoring
the performance of the Existing Owner in the completion, following each
applicable Land Interest Acquisition Date, of all outstanding punch list items
in respect of the relevant Improvements and all other obligations of the Existing
Owner in respect of the Property following each Land Interest Acquisition
Date.  The Lessee hereby unconditionally
agrees to act as said agent on behalf of the Lessor.

             2.3        Lease Term.  The term of this Lease (the "Term")
shall begin (1) with respect to the Phase I Facility, on the Land Interest
Acquisition Date applicable thereto; and (2) with respect to the Phase II
Facility, on the Land Interest Acquisition Date applicable thereto and, in each
case, shall end on the fifth anniversary of the Closing Date, unless the Term
is renewed or earlier terminated in accordance with the provisions of this
Lease.

             2.4        Title.  The Property is leased to the Lessee without
any representation or warranty of title, condition of any of the Improvements
or permitted uses, express or implied, by the Lessor and subject to the rights
of parties in possession, the existing state of title (including, without
limitation, the Permitted Exceptions) and all applicable Requirements of
Law.  The Lessee shall in no event have
any recourse against the Lessor for any defect in or exception to title to the
Property, other than for any such defect or exception constituting a Lessor
Lien.

ARTICLE III.

             3.1        
Rent.

                           (a)        
 During the Term, the Lessee shall pay
Basic Rent on each Payment Date, on the date required under Section 22.1(i)
in connection with the Lessee's exercise of the Remarketing Option and on any
date on which this Lease shall terminate.

                           (b)        Neither the Lessee's
inability or
failure to take possession of all or any portion of the Property when delivered
by the Lessor, nor the Lessor's inability or failure to deliver all or any
portion of the Property to the Lessee on or before the contemplated Lease
Commencement Date therefor, whether or not attributable to any act or omission
of the Lessee or any act or omission of the Lessor, or for any other reason
whatsoever (including any act or omission of the Existing Owner), shall delay
or otherwise affect the Lessee's obligation to pay Rent for the Property from
and after commencement of the Term.

             3.2        Payment of Basic Rent.  Basic Rent shall be paid absolutely net to
the Lessor, so that this Lease shall yield to the Lessor the full amount
thereof, without setoff, deduction or reduction, whether or not the Lessee's
quiet possession of the Property is disturbed.

             3.3        Supplemental Rent.  The Lessee shall pay to the Lessor or the
Person entitled thereto any and all Supplemental Rent promptly as the same
shall become due and payable, and if the Lessee fails to pay any Supplemental
Rent, the Lessor shall have all rights, powers and remedies provided herein or
by law or equity or otherwise in the case of nonpayment of Basic Rent.  The Lessee shall pay to the Lessor, as
Supplemental Rent, among other things, on demand, to the extent permitted by
Applicable Law, interest at the applicable Overdue Rate on any installment of
Basic Rent not paid when due for the period for which the same shall be overdue
and on any payment of Supplemental Rent not paid when due or demanded by the
Lessor for the period from the due date or the date of any such demand, as the
case may be, until the same shall be paid. 
The expiration or other termination of the Lessee's obligations to pay
Basic Rent hereunder shall not limit or modify the obligations of the Lessee
with respect to Supplemental Rent. 
Unless expressly provided otherwise in this Lease, in the event of any
failure on the part of the Lessee to pay and discharge any Supplemental Rent as
and when due, the Lessee shall also promptly pay and discharge any fine,
penalty, interest or cost which may be assessed or added under any agreement
with a third party for nonpayment or late payment of such Supplemental Rent,
all of which shall also constitute Supplemental Rent.

             3.4        Method of Payment.  Each payment of Rent shall be made by the
Lessee to the Lessor by 12:00 noon, Chicago time, at the place of payment
designated by Agent in funds consisting of lawful currency of the United States
of America which shall be immediately available on the scheduled date when such
payment shall be due, unless such scheduled date shall not be a Business Day,
in which case such payment shall be made on the next succeeding Business Day or
as otherwise required by the definition of the term "Interest Period"
set forth in Appendix 1 hereto. 
Payments initiated after 12:00 noon, Chicago time shall be deemed
received on the next succeeding Business Day for purposes of the second
sentence of Section 3.3 hereof, but shall be deemed received on the same
day for purposes of Section 17.1 hereof.

ARTICLE
IV.

             4.1        Utility Charges.  Subject to the Lessee's rights under the
terms of Article XIII relating to permitted contests, the Lessee shall
pay or cause to be paid all charges for electricity, power, gas, oil, water,
telephone, sanitary sewer service and all other rents and utilities used in or
on the Property during the Term.  The
Lessee shall be entitled to seek and receive any credit or refund with respect
to any utility charge paid by the Lessee and the amount of any credit or refund
received by the Lessor on account of any utility charges paid by the Lessee,
net of the costs and expenses reasonably incurred by the Lessor in obtaining
such credit or refund, shall be promptly paid over to the Lessee.  All charges for utilities imposed with
respect to the Property for a billing period during which this Lease expires or
terminates shall be adjusted and prorated on a daily basis between the Lessor
and the Lessee, and each party shall pay or reimburse the other for each
party's pro rata share thereof, except that if the Lessee retains possession of
the Property after termination or expiration of this Lease, no such adjustment
and proration shall be made.

ARTICLE V.

             5.1        Quiet Enjoyment.  Subject to the rights of the Lessor
contained in Section 17.2 and the other terms of this Lease and so long
as no Event of Default shall have occurred and be continuing, the Lessee shall
peaceably and quietly have, hold and enjoy the Property for the Term, free of
any claim or other action by the Lessor or anyone rightfully claiming by,
through or under the Lessor (other than the Lessee) with respect to any matters
arising from and after (i) the Land Interest Acquisition Date therefor, in
the case of the Phase I Facility, and (ii) the Land Interest Acquisition Date
therefor, in the case of the Phase II Facility.

ARTICLE
VI.

             6.1        Net Lease.
This Lease shall constitute a net lease. 
It is the further express intent of the Lessor and the Lessee that the
obligations of the Lessor and the Lessee hereunder shall be separate and independent
covenants and agreements and that the Basic Rent and Supplemental Rent, and all
other charges and sums payable by the Lessee hereunder, shall commence at the
times provided herein and shall continue to be payable in all events unless the
obligations to pay the same shall be terminated pursuant to an express
provision in this Lease.  Any present or
future law to the contrary notwithstanding, this Lease shall not terminate, nor
shall the Lessee be entitled to any abatement, suspension, deferment, reduction,
setoff, counterclaim, or defense (other than the defense of payment) with
respect to the Rent, nor shall the obligations of the Lessee hereunder be
affected (except as expressly herein permitted and by performance of the
obligations in connection therewith) by reason of: (i) any defect in the
condition, merchantability, design, construction, quality or fitness for use of
the Property or any portion thereof, or the failure of the Property to comply
with all Requirements of Law and Insurance Requirements, including any
inability to occupy or use the Property or any portion thereof by reason of
such non–compliance; (ii) any damage to, removal, abandonment, salvage,
loss, contamination of or Release from, scrapping or destruction of, or any
requisition or taking of the Property or any portion thereof; (iii) any
restriction, prevention or curtailment of or interference with any use of the
Property or any portion thereof; (iv) any defect in title to or rights to the
Property or any portion thereof or any Lien on such title or rights or on the
Property (other than Lessor Liens); (v) any change, waiver, extension,
indulgence or other action or omission or breach in respect of any obligation
or liability of or by the Lessor, the Agent or any Participant (other than the
breach by the Lessor of its covenant of quiet enjoyment set forth in Section
5.1); (vi) any bankruptcy, insolvency, reorganization, composition,
adjustment, dissolution, liquidation or other like proceedings relating to the
Lessee, the Lessor, the Agent, any Participant or any other Person, or any
action taken with respect to this Lease by any trustee or receiver of the
Lessee, the Lessor, the Agent, any Participant or any other Person, or by any
court, in any such proceeding; (vii) any claim that the Lessee has or might
have against any Person, including without limitation the Lessor, the Existing
Owner, any vendor, manufacturer, contractor of or for the Property, the Agent
or any Participant;  (viii) any failure
on the part of the Lessor to perform or comply with any of the terms of this
Lease, any other Operative Document or any other agreement (other than the
breach by the Lessor of its covenant of quiet enjoyment set forth in Section
5.1); (ix) any invalidity or unenforceability or illegality or
disaffirmance of this Lease, against or by the Lessee or any provision hereof
or any of the other Operative Documents or any provision of any thereof; (x)
the impossibility or illegality of performance by the Lessee, the Lessor or
both; (xi) any action by any court, administrative agency or other Governmental
Authority; (xii) any restriction, prevention or curtailment of or interference
with the construction on or any use of the Property or any portion thereof; or
(xiii) any other cause or circumstances whether similar or dissimilar to the
foregoing and whether or not the Lessee shall have notice or knowledge of any
of the foregoing.  The parties intend
that the obligations of the Lessee hereunder shall be covenants and agreements
that are separate and independent from any obligations of the Lessor hereunder
or under any other Operative Document and the obligations of the Lessee shall
continue unaffected unless such obligations shall have been modified or
terminated in accordance with an express provision of this Lease.

             6.2        No Termination or Abatement.  The Lessee shall remain obligated under this
Lease in accordance with its terms and shall not take any action to terminate
(except as provided herein), rescind or avoid this Lease, notwithstanding any
action for bankruptcy, insolvency, reorganization, liquidation, dissolution, or
other proceeding affecting the Lessor, the Agent, any Participant or the Lessee
or any action with respect to this Lease or any Operative Document which may be
taken by any trustee, receiver or liquidator of the Lessor, the Agent, any
Participant or the Lessee or by any court with respect to the Lessor, the Agent
or any Participant.  The Lessee hereby
waives, to the extent permitted by Applicable Law, all right (i) to terminate
or surrender this Lease (except as provided herein) or (ii) to avail itself of
any abatement, suspension, deferment, reduction, setoff, counterclaim or
defense (other than the defense of payment) with respect to any Rent.  The Lessee shall remain obligated under this
Lease in accordance with its terms and the Lessee hereby waives, to the extent
permitted by Applicable Law, any and all rights now or hereafter conferred by
statute or otherwise to modify or to avoid strict compliance with its
obligations under this Lease. 
Notwithstanding any such statute or otherwise, the Lessee shall be bound
by all of the terms and conditions contained in this Lease.

ARTICLE VII.

             7.1        Nature of Transaction; Intent of the Parties.

                           (a)         It is the intent
of the parties hereto
that: (i) this Lease constitutes an "operating lease" pursuant to
Statement of Financial Accounting Standards No. 13, as amended and interpreted,
for purposes of the 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 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 Y 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)        Anything to the contrary
in the
Operative Documents notwithstanding, the Lessor and the Lessee intend and agree
that with respect to the nature of the transactions evidenced by this Lease in
the context of the exercise of remedies under the Operative Documents,
including, without limitation, 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 or 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 this Lease 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 this Lease to pay Basic Rent, Supplemental Rent, Asset Termination
Value or Residual Value Guarantee Amount in connection with a purchase of the
Property pursuant to this Lease shall be treated as payments of interest on
(with respect to Basic Rent), and principal of, respectively, loans from the
Lessor and the Participants to the Lessee, and (iii) this Lease grants a
security interest and mortgage or deed of trust lien, as the case may be, in
the Property to the Lessor and the Lease has been assigned by the Lessor to the
Agent for the benefit of the Participants to secure the Lessee's performance
under and payment of all amounts under this Lease and the other Operative
Documents.

                           (c)         Specifically, without limiting the

generality of subsection (b) of this Section 7.1, the Lessor and the Lessee
further intend and agree that, for the purpose of securing the Lessee's
obligations for the repayment of the above–described loans from the
Lessor and the Participants to the Lessee (the aggregate commitment from the
Participants as of the date hereof is Two Hundred Seventy Million Dollars
($270,000,000) and the maturity date of such loans as of the date hereof is March
16, 2006,), (i) this Lease shall also be deemed to be a security agreement and
financing statement within the meaning of Article 9 of the Uniform Commercial
Code and a real property mortgage of the Property; (ii) the conveyance provided
for in Article II shall be deemed to be a grant by the Lessee to the Lessor,
assigned by the Lessor to the Agent for the benefit of the Participants, of a
mortgage lien and security interest in all of the Lessee's right, title and
interest in and to the Property, except to the extent all or a portion of the
Property is released from this Lease in accordance with the Operative
Documents, and all proceeds of the conversion, voluntary or involuntary, of the
foregoing into cash, investments, securities or other property, whether in the
form of cash, investments, securities or other property (it being understood
that the Lessee hereby mortgages and warrants and grants a security interest in
the Property to Lessor to secure such loans); (iii) the possession by the
Lessor or any of its agents of any of the Collateral (as defined below) which
constitutes notes and such other items of property as constitute instruments,
money, negotiable documents or chattel paper shall be deemed to be
"possession by the secured party" for purposes of perfecting the
security interest pursuant to Section 9–305 of the Uniform Commercial
Code; and (iv) notifications to Persons holding such property, and
acknowledgments, receipts or confirmations from financial intermediaries,
bankers or agents (as applicable) of the Lessee shall be deemed to have been
given for the purpose of perfecting such security interest under Applicable
Law; provided that the foregoing provisions of this subsection 7.1(c) shall not
be deemed or construed so as to constitute the transactions evidenced under
this Lease as loans other than for the purposes described in subsection
7.1(a)(ii) and/or under the circumstances described in subsection 7.1(b).  The Lessor and the Lessee shall, to the extent
consistent with this Lease, take such actions and execute, deliver, file and
record such other documents, financing statements, mortgages and deeds of trust
as may be necessary to ensure that, if this Lease were deemed to create a
security interest in the Property in accordance with this Section, such
security interest would be deemed to be a perfected security interest of first
priority (subject to Permitted Exceptions) under Applicable Law and will be
maintained as such throughout the Term.

                           (d)        If the transactions
evidenced by this
Lease and the other Operative Documents can no longer be treated as an
operating lease pursuant to GAAP for accounting purposes (other than by reason
of the failure of the Lessor to maintain the minimum equity required by EITF
Issues 96–21 and 97–1), all provisions in the Operative Documents
limiting the Lessee's obligation to pay the Asset Termination Value (including
the Remarketing Option) on the Expiration Date or otherwise shall no longer
apply.  If any such change in accounting
treatment shall occur, the Lessee, 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 reflect the foregoing.

                           (e)         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 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 Lease and the
other Operative Documents in light of such revisions or amendments.

                           (f)         Specifically,
without limiting the
generality of subsection (b) of Section 7.1, in order to
secure the Lessee's obligation to pay Basic Rent, Supplemental Rent, Asset
Termination Value, the Residual Value Guarantee Amount, the Purchase Option
Price and all other obligations owing by the Lessee under the Operative Documents
(the "Obligations"), the Lessee hereby grants, remises,
releases, aliens, conveys, transfers, mortgages, assigns and warrants to First
American Title Insurance Company, as trustee (as "Trustee")
for the benefit of Lessor WITH POWER OF SALE and right of entry and possession,
all of the Lessee's  right, title and
interest in and to the following (collectively, the "Collateral"):

                           (i)          all right,
title and interest of the
Lessee in and to the Property or any part thereof and the reversions,
remainders, rents, issues and profits thereof;

                           (ii)         all right, title
and interest of the
Lessee in and to all Fixtures and Improvements and all substitutes and
replacements of, and all additions and improvements to, the Improvements and
the Fixtures, subsequently acquired by the Lessee or constructed, assembled or
placed by Lessee on any of the Land Interest, immediately upon such
acquisition, release, construction, assembling or placement, including, without
limitation, any and all building materials whether stored at the Property or
offsite, and, in each such case, without any further mortgage, deed of trust,
conveyance, assignment or other act by the Lessee;

                           (iii)        all right, title and
interest of the
Lessee in, to and under all books and records relating to or used in connection
with the operation of the Property or the Fixtures or any part thereof and the
Equipment;

                           (iv)       all right, title and interest of the
Lessee in and to all insurance policies (including title insurance policies)
required to be maintained by the Lessee pursuant to the Operative Documents,
including the right to collect and receive such proceeds; and all awards and
other compensation, including the interest payable thereon and the right to
collect and receive the same, made to the owner of the Property for the taking
by eminent domain, condemnation or otherwise, of all or any part of the
Property or any easement or other right therein;

                           (v)        all right, title and
interest of the
Lessee in and to (i) all consents, licenses, building permits, certificates of
occupancy and other governmental approvals relating to construction,
completion, occupancy, use or operation of the Property or any portion thereof,
provided that any such consent, license, permit, certificate or approval
that by its terms or by operation of law would become void, voidable,
terminable or revocable or would result in a breach or default thereunder or
under any applicable law if subjected to the lien granted pursuant to this clause
(v) is expressly excepted and excluded from this clause (v) to the
extent necessary to avoid such result, and (ii) all plans and specifications
relating to the Property or any portion thereof, in each case to the extent
assignable;

                           (vi)       all Rent and all other rents,
payments,
purchase prices, receipts, revenues, issues and profits payable under this
Lease or pursuant to any other lease with respect to the Property;

                           (vii)      all proceeds, both cash and
noncash, of
the foregoing and any items acquired in substitution of, or replacement for,
any of the foregoing; and

                           (viii)     all right, title and interest of the
Lessee
in and to all of the Operative Documents, including, without limitation, each
Lease Supplement, regardless of whether the interest of the Lessee therein is
that of lessee, sublessee, sublessor or borrower.

ARTICLE VIII.

             8.1        Condition of the Property.  THE LESSEE ACKNOWLEDGES AND AGREES THAT
ALTHOUGH THE LESSOR WILL HOLD FEE TITLE TO THE PROPERTY, THE LESSEE IS SOLELY
RESPONSIBLE FOR THE IMPROVEMENTS AND ANY ALTERATIONS OR MODIFICATIONS.  THE LESSEE FURTHER ACKNOWLEDGES AND AGREES THAT
IT IS LEASING THE PROPERTY "AS IS" WITHOUT REPRESENTATION, WARRANTY
OR COVENANT (EXPRESS OR IMPLIED) BY THE LESSOR, THE AGENT OR ANY PARTICIPANT
AND IN EACH CASE SUBJECT TO (A) THE EXISTING STATE OF TITLE, (B) THE RIGHTS OF
ANY PARTIES IN POSSESSION THEREOF, (C) ANY STATE OF FACTS WHICH AN ACCURATE
SURVEY OR PHYSICAL INSPECTION MIGHT SHOW, AND (D) VIOLATIONS OF REQUIREMENTS OF
LAW WHICH MAY EXIST ON THE DATE HEREOF. 
NEITHER THE LESSOR, THE AGENT NOR ANY PARTICIPANT HAS MADE OR SHALL BE
DEEMED TO HAVE MADE ANY REPRESENTATION, WARRANTY OR COVENANT (EXPRESS OR
IMPLIED) OR SHALL BE DEEMED TO HAVE ANY LIABILITY WHATSOEVER AS TO THE TITLE
(EXCEPT FOR THE LESSOR'S COVENANT OF QUIET ENJOYMENT SET FORTH IN SECTION
5.1), VALUE, HABITABILITY, USE, CONDITION, DESIGN, OPERATION, OR FITNESS
FOR USE OF THE PROPERTY (OR ANY PORTION THEREOF, INCLUDING ANY IMPROVEMENTS
EXISTING THEREON), OR ANY OTHER REPRESENTATION, WARRANTY OR COVENANT
WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO THE PROPERTY (OR ANY PORTION
THEREOF, INCLUDING ANY IMPROVEMENTS EXISTING THEREON) AND NEITHER THE LESSOR,
THE AGENT NOR ANY PARTICIPANT SHALL BE LIABLE FOR ANY LATENT, HIDDEN, OR PATENT
DEFECT THEREIN OR THE FAILURE OF THE PROPERTY, OR ANY PART THEREOF, TO COMPLY
WITH ANY REQUIREMENT OF LAW.

             8.2        Possession and Use of the Property.
The Property shall be used in a manner consistent with properties of a similar
nature in the businesses in which the Lessee is engaged or as permitted in any
sublease or assignment allowed by Section 25.1 hereof and in compliance
in all respects with any covenants, conditions and restrictions of record and
any ordinance or law affecting the use and occupancy of the Property; and provided
that such other uses do not increase the liability, directly or indirectly, of
the Lessor or adversely affect the value, utility or remaining useful life of
the Property.  At all times during the
applicable Term, the Property shall not be abandoned by the Lessee or a
permitted assignee or sublessee.  The
Lessee shall pay, or cause to be paid, all charges and costs required in
connection with the use of the Property as contemplated by this Lease.  The Lessee shall not commit or permit any
waste of the Property or any portion thereof.

ARTICLE IX.

             9.1        Compliance with Requirements of Law and Insurance
Requirements.  Subject to the terms of Article XIII
relating to permitted contests, the Lessee, at its sole cost and expense, shall
(a) comply with all Requirements of Law and all Insurance Requirements relating
to the Property, including the construction, use, operation, maintenance,
repair and restoration thereof and the remarketing thereof pursuant to Article
XXII, whether or not compliance therewith shall require structural or
extraordinary changes in the Improvements or interfere with the use and
enjoyment of the Property, and (b) procure, maintain and comply with all
licenses, permits, orders, approvals, consents and other authorizations
required for the construction, use, maintenance and operation of the Property
and for the use, operation, maintenance, repair and restoration of the
Improvements.

ARTICLE
X.

             10.1     Maintenance and Repair; Return.

                           (a)         The Lessee, at its
sole cost and
expense, shall maintain the Property in good working order, mechanical
condition and repair, subject to reasonable wear and tear, and make all necessary
repairs thereto, of every kind and nature whatsoever, whether interior or
exterior, ordinary or extraordinary, structural or nonstructural or foreseen or
unforeseen, in each case in compliance with all applicable Requirements of Law
and in compliance with all Insurance Requirements and on a basis consistent
with the operation and maintenance of commercial properties comparable in type
and location to the Property and in compliance with prudent industry practice.

                           (b)        The Lessor shall under
no circumstances
be required to build any improvements on the Property, make any repairs,
replacements, alterations or renewals of any nature or description to the
Property, make any expenditure whatsoever in connection with this Lease or
maintain the Property in any way.  The
Lessor shall not be required to maintain, repair or rebuild all or any part of
the Property, and the Lessee waives any right to (i) require the Lessor to
maintain, repair, or rebuild all or any part of the Property, or (ii) make
repairs at the expense of the Lessor pursuant to any Requirement of Law,
Insurance Requirement, contract, agreement, or covenant, condition or
restriction in effect at any time during the Term.

                           (c)         The Lessee shall,
upon the expiration
or earlier termination of this Lease (unless the Property is conveyed to the
Lessee as provided herein), vacate and surrender the Property to the Lessor in
its then-current, "AS IS" condition, subject to the Lessee's
obligations under Sections 9.1, 10.1(a), 11.1, 12.1,
15.1(e), 15.2, 17.2(h), 22.1 and 23.1.

ARTICLE XI.

             11.1     Modifications, Substitutions and Replacements.

                           (a)         The Lessee, at its
sole cost and
expense, may at any time and from time to time make alterations, renovations,
improvements and additions to the Property or any portion thereof and
substitutions and replacements therefor (collectively, "Modifications");
provided that: (i) no Modification shall impair the value, utility or
remaining useful life of the Property or any part thereof from that which
existed immediately prior to such Modification; (ii) the Modification shall be
done expeditiously and in a good and workmanlike manner; (iii) the Lessee shall
comply with all Requirements of Law and all Insurance Requirements applicable
to the Modification, including the obtaining of all permits and certificates of
occupancy, and the structural integrity of the Property shall not be adversely
affected; (iv) subject to the terms of Article XIII relating to
permitted contests, the Lessee shall pay all costs and expenses and shall
discharge (or cause to be insured or bonded over) within sixty (60) days after
the same shall be filed (or otherwise become effective) any Liens arising with
respect to the Modification; and (v) such Modifications shall comply with Sections
8.2 and 10.1.  All
Modifications (other than those that both are not Modifications required to be
made pursuant to a Requirement of Law or an Insurance Requirement ("Required
Modification") and are readily removable without impairing the value,
utility or remaining useful life of the Property) shall remain part of the
realty and shall be subject to this Lease, and title thereto shall immediately
vest in the Lessor.  So long as no Event
of Default has occurred and is continuing, the Lessee may place upon the
Property any trade fixtures, machinery, equipment or other property belonging
to the Lessee or third parties and may remove the same at any time during the
Term, subject, however, to the terms of Section 10.1(a); provided
that such trade fixtures, machinery, equipment or other property do not impair
the value, utility or remaining useful life of the Property; provided, further,
that the Lessee shall keep and maintain at the Property and shall not remove
from the Property any Equipment financed or otherwise paid for (directly or
indirectly) by the Lessor or any Participant pursuant to the Participation
Agreement.

                           (b)        The Lessee shall deliver
to the Lessor
and the Agent and each Participant a brief written narrative description of the
work to be done in connection with any Modification to the Property the cost of
which is anticipated to exceed $1,000,000 in the aggregate.

ARTICLE XII.

             12.1     <
u>Warranty of Title.

                           (a)         The Lessee agrees
that except as
otherwise provided herein and subject to the terms of Article XIII
relating to permitted contests, the Lessee shall not directly or indirectly
create or allow to remain, and shall promptly discharge at its sole cost and
expense, any Lien, defect, attachment, levy, title retention agreement or claim
upon the Property (or the Lessor's interest therein) or any Modifications or
any Lien, attachment, levy or claim with respect to the Rent, the Cash
Collateral or with respect to any amounts held by the Agent or any other Person
pursuant to the Participation Agreement or the other Operative Documents, other
than, with respect to the Property only, Permitted Exceptions and Lessor Liens.

                           (b)        Nothing contained in
this Lease shall be
construed as constituting the consent or request of the Lessor, expressed or
implied, to or for the performance by any contractor, mechanic, laborer,
materialman, supplier or vendor of any labor or services or for the furnishing
of any materials for any construction, alteration, addition, repair or
demolition of or to the Property or any part thereof.  NOTICE IS HEREBY GIVEN THAT NEITHER THE LESSOR, ANY PARTICIPANT
NOR THE AGENT IS OR SHALL BE LIABLE FOR ANY LABOR, SERVICES OR MATERIALS  FURNISHED OR TO BE FURNISHED TO THE LESSEE,
OR TO ANYONE HOLDING THE PROPERTY OR ANY PART THEREOF THROUGH OR UNDER THE
LESSEE AND THAT NO MECHANIC'S OR OTHER LIENS FOR ANY SUCH LABOR, SERVICES OR
MATERIALS SHALL ATTACH TO OR AFFECT THE INTEREST OF THE LESSOR IN AND TO THE
PROPERTY.

             12.2     Grants and Releases of Easements and Other Agreements.
Provided that no Event of Default shall have occurred and be continuing and
subject to the provisions of Articles VIII, IX, X and XI,
the Lessor hereby consents in each instance to the following actions by the
Lessee, in the name and stead of the Lessor, but at the Lessee's sole cost and
expense: (a) the granting of easements, licenses, rights-of-way and other
rights and privileges in the nature of easements reasonably necessary or
desirable for the use, repair, operation or maintenance of the Property as
herein provided; (b) the release of easements, licenses, rights-of-way and
other rights and privileges in the nature of easements which are for the
benefit of the Property; (c) the execution of petitions to have the Property
annexed to any municipal corporation or utility district; and (d) the execution
of amendments to any covenants, restrictions, easements, licenses,
rights-of-way, and other rights and privileges in the nature of easements
affecting the Property; provided, however, in each case the
Lessee shall have delivered to the Lessor a Responsible Officer's Certificate
stating that (i) such grant, release, contract or agreement does not materially
impair the value, utility and remaining useful life of the Property, (ii) such
grant, release, contract or agreement is reasonably necessary for the use,
operation, maintenance, alteration or improvement of the Property, (iii) the
Lessee shall remain obligated under this Lease and under any instrument
executed by the Lessee consenting to the assignment of the Lessor's interest in
this Lease as security for indebtedness, in each such case in accordance with
their terms, as though such grant, release, contract, agreement or transfer had
not been effected, and (iv) the Lessee shall pay and perform any obligations of
the Lessor under such grant, release, contract or agreement.  Without limiting the effectiveness of the
foregoing, provided that no Event of Default shall have occurred and be
continuing, the Lessor shall, upon the request of the Lessee, and at the Lessee's
sole cost and expense, execute and deliver, any instruments necessary or
appropriate to confirm any such grant, agreement or release to any Person
permitted under this Section 12.2.

ARTICLE XIII.

             13.1     Permitted Contests Other Than in Respect of Indemnities.
Except to the extent otherwise provided for in Section 13 of the Participation
Agreement, the Lessee, on its own or on the Lessor's behalf but at the Lessee's
sole cost and expense, may contest, by appropriate administrative or judicial
proceedings conducted in good faith and with due diligence, the amount,
validity or application, in whole or in part, of any Requirement of Law, or
utility charges payable pursuant to Section 4.1 or any Lien, attachment,
levy, encumbrance or encroachment, and the Lessor agrees not to pay, settle or
otherwise compromise any such item, provided that (a) the commencement
and continuation of such proceedings shall suspend the collection thereof from,
and suspend the enforcement thereof against, the Property, the Cash Collateral,
the Lessor, the Agent and the Participants or the Lessee shall have bonded or
otherwise secured such amount in a manner satisfactory to the Lessor and the
Agent; (b) there shall be no risk of the imposition of a Lien as a result of
such contest (other than, as to the Property, Permitted Exceptions) on the
Property or the Cash Collateral, and no part of the Property or the Cash
Collateral, nor any Rent would be in any danger of being sold, forfeited, lost
or deferred as a result of such contest; (c) at no time during the permitted contest
shall there be a risk of the imposition of criminal liability or material civil
liability on the Lessor, the Agent or any Participant for failure to comply
therewith (unless, in the case of civil liability, the Lessee shall have bonded
or otherwise secured such amount in a manner satisfactory to the Lessor and the
Agent); and (d) in the event that, at any time, there shall be a material risk
of extending the application of such item beyond the end of the Term, then the
Lessee shall deliver to the Lessor a Responsible Officer's Certificate
certifying as to the matters set forth in clauses (a), (b) and (c)
of this Section 13.1. The Lessor, at the Lessee's sole cost and expense,
shall cooperate in good faith with the Lessee with respect to any permitted contests
conducted by the Lessee pursuant to this Section 13.1 and shall, at the
Lessee's sole cost and expense, execute and deliver to the Lessee such
authorizations and other documents as may reasonably be required in connection
with any such contest and, if reasonably requested by the Lessee, shall join as
a party therein at the Lessee's sole cost and expense.

ARTICLE XIV.

             14.1     General Liability and Workers' Compensation Insurance.  The Lessee shall procure and carry
commercial general liability insurance, including contractual liability, for
claims for injuries or death sustained by persons or damage to property while
on the Property and such other general liability coverages as are ordinarily
procured by Persons who own or operate similar properties and consistent with
prudent business practice, which policies shall include contractual liability
endorsements covering the Lessee's indemnification obligations in Section 13.1
of the Participation Agreement.  Such
insurance shall be on terms and in amounts (which shall be acceptable to the
Lessor and in the event of liability insurance shall be maintained at a level
set forth on Schedule 14.2) that are no less favorable than insurance
maintained by the Lessee and its Subsidiaries with respect to similar properties
that it owns and that are in accordance with prudent business practice and may
be provided under blanket policies maintained by or on behalf of the Lessee and
its Subsidiaries.  The policy shall be
endorsed to name the Lessor, the Agent and each Participant as additional
insureds.  The policy shall also
specifically provide that the policy shall be considered primary insurance
which shall apply to any loss or claim before any contribution by any insurance
which the Lessor, the Agent or the Participants may have in force.  The Lessee shall, in the operation of the
Property (including in connection with any Modifications thereof) comply with
the applicable workers' compensation laws and protect the Lessor, the Agent and
the Participants against any liability under such laws.

             14.2     
Hazard and Other Insurance.
The Lessee shall keep, or cause to be kept, the Property insured against loss
or damage by fire, flood and other risks (excluding earthquake, which insurance
may be obtained by the Lessee if it so elects but which shall not be required
hereunder) in an amount not less than the greater of the amount set forth on Schedule
14.2 and the then current replacement costs of the buildings and
improvements on the Property and on terms that are no less favorable than
insurance covering other similar properties owned or leased by the Lessee and
that are in accordance with prudent business practice.  The Lessee may provide such coverage under
blanket policies maintained by or on behalf of the Lessee; provided,
that if the Lessee does not elect to terminate the Lease pursuant to Article
XVI hereof following the occurrence of an event covered by any such blanket
policy, the proceeds of any such blanket policy shall be applied first, to the
exclusion of other facilities covered by such policy other than the Property,
to the repair, rebuilding and restoration of any damage to the Property.  Insurance coverage required under this Section
14.2 shall be subject to deductibles reasonably satisfactory to the
Lessor.  During the construction of any
Modifications the Lessee shall also maintain builders' risk insurance.  Each policy of insurance maintained by the
Lessee pursuant to this Section 14.2 shall provide that all insurance
proceeds in respect of any loss or occurrence shall be paid to and adjusted
solely by (and such proceeds shall be paid to) the Lessee, except from and
after the date on which the insurer receives written notice from the Lessor or
the Agent that a Event of Default exists (and unless and until such insurer
receives written notice from the Lessor or the Agent that all Events of Default
have been cured), all losses shall be adjusted solely by, and all insurance
proceeds shall be paid solely to, the Agent (or the Lessor if the Participation
Interests have been fully paid) for application pursuant to Article XV.  The costs and expenses of all insurance
required under this Section 14.2 shall be at the sole cost and expense
of the Lessee.

             14.3     
Coverage.

                           (a)         The Lessee shall
furnish the Lessor and
the Agent with certificates of insurance and certified copies of the insurance
policies on each Land Interest Acquisition Date showing the insurance then
required under Sections 14.1 and 14.2 to be in effect and naming
the Lessor, the Agent and each Participant as additional insureds and, with
respect to the insurance required under Section 14.2 (and with respect
to any earthquake insurance covering the Property which Lessee may elect to
purchase and maintain), naming the Agent, for the benefit of the Participants,
as loss payees, and showing the mortgagee endorsement required by Section
14.3(c).  All such insurance shall
be at the cost and expense of the Lessee. 
Such policies and certificates in respect thereof shall include a
provision for thirty (30) days' advance written notice by the insurer to the
Lessor and the Agent in the event of cancellation of or any significant
reduction in the coverage provided by such insurance.

                           (b)        The Lessee agrees that
the insurance
policy or policies required by Sections 14.1 and 14.2 shall
include (i) an appropriate clause pursuant to which such policy shall provide
that it will not be invalidated should the Lessee waive, in writing, prior to a
loss, any or all rights of recovery against any party for losses covered by
such policy, and that the insurance in favor of the Lessor, the Agent and the
Participants, and their respective rights under and interests in said policies
shall not be invalidated or reduced by any act or omission or negligence of the
Lessee or any other Person having any interest in the Property, and (ii) a
so-called "Waiver of Subrogation Clause".  The Lessee hereby waives any and all such rights against the
Lessor, the Agent and the Participants to the extent of payments made under
such policies.

                           (c)         All such insurance shall be
written by
reputable insurance companies that are financially sound and solvent and
otherwise reasonably appropriate considering the amount and type of insurance
being provided by such companies.  Any
insurance company selected by the Lessee which is rated in Best's Key Rating
Guide or any successor thereto (or if there be none, an organization having a
similar national reputation) shall have a general policyholder rating of
"A–" and a financial rating of at least IX in Best's Key Rating
Guide or be otherwise acceptable to the Lessor and the Agent.  All insurance policies required by Section
14.2 shall include a standard form mortgagee endorsement in favor of the
Agent.

                           (d)        The Lessor shall not
carry separate
insurance concurrent in kind or form or contributing in the event of loss with
any insurance required under this Article XIV except that the Lessor may
carry separate liability insurance (at its sole cost) so long as (i) the
Lessee's insurance is designated as primary and in no event excess or
contributory to any insurance the Lessor may have in force which would apply to
a loss covered under the Lessee's policy and (ii) each such insurance policy
will not cause the Lessee's insurance required under this Article XIV to
be subject to a coinsurance exception of any kind.

                           (e)         The Lessee shall
pay as they become due
all premiums for the insurance required by Section 14.1 and, when
required under Section 14.2, for the insurance required under Section
14.2, and shall renew or replace each policy prior to the expiration date
thereof.  At the time each of the
Lessee's insurance policies is renewed (but in no event less frequently than
once each year), the Lessee shall deliver to the Lessor and the Agent certificates
of insurance with respect to the insurance policies required by this Article
XIV to be maintained by the Lessee with respect to the Property.

                           (f)         The Lessee hereby
waives, releases and
discharges the Lessor, the Agent and each Participant and their agents and
employees from all claims whatsoever arising out of loss, claim, expense or
damage to or destruction covered or coverable by insurance required under this Article
XIV notwithstanding that such loss, claim, expense or damage may have been
caused by the Lessor, the Agent or any Participant or any of their agents or
employees, and the Lessee agrees to look to the insurance coverage only in the
event of such loss.

ARTICLE
XV.

             15.1     Casualty and Condemnation.

                           (a)         Subject to the
provisions of Article
XIV, this Article XV and (in the event the Lessee delivers, or is
obligated to deliver, a Termination Notice) Article XVI, and prior to
the occurrence and continuation of a Event of Default, the Lessee shall be
entitled to receive (and the Lessor shall pay over to the Lessee, if received by
the Lessor, and hereby irrevocably assigns to the Lessee all of the Lessor's
right, title and interest in) any award, compensation or insurance proceeds to
which the Lessee or the Lessor may become entitled by reason of their
respective interests in the Property (i) if all or a portion of the Property is
damaged or destroyed in whole or in part by a Casualty or (ii) if the use,
access, occupancy, easement rights or title to the Property or any part
thereof, is the subject of a Condemnation; provided, however,
subject to Article XIV, if a Event of Default shall have occurred and be
continuing, such award, compensation or insurance proceeds shall be paid
directly to the Agent or, if received by the Lessee, shall be held in trust for
the Agent, and shall be paid over by the Lessee to the Agent (or, if the
Participation Interests have been fully paid, to the Lessor) and held in
accordance with the terms of this paragraph (a).  If, contrary to such provision, any such
award, compensation or insurance proceeds are paid to the Lessor or the Lessee
rather than to the Agent, the Lessor and the Lessee, as the case may be, hereby
agree to transfer any such payment to the Agent.  All amounts held by the Lessor or the Agent under the preceding
sentences on account of any award, compensation or insurance proceeds either
paid directly to the Lessor or the Agent or turned over to the Lessor or the
Agent shall either be (i) paid to the Lessee for the repair of damage caused by
such Casualty or Condemnation in accordance with paragraph (e) of this Section
15.1, or (ii) applied to the purchase price of the Property on a
Termination Date resulting from a Casualty or Condemnation in accordance with paragraph
(d) of this Section 15.1 or paragraph (a) of Section 16.2,
with any Excess Proceeds being payable to the Lessee.

                           (b)        In any proceeding or action under the
control of the Lessor or the Agent pursuant to the terms of Section 14.2,
the Lessee may participate and shall pay all expenses of such proceeding and
its participation.  At the Lessee's
reasonable request, and at the Lessee's sole cost and expense, the Lessor and
the Agent shall participate in any such proceeding, action, negotiation,
prosecution or adjustment under the control of the Lessee.  The Lessor and the Lessee agree that this
Lease shall control the rights of the Lessor and the Lessee in and to any such
award, compensation or insurance payment.

                           (c)         If the Lessor or
the Lessee shall
receive notice of a Casualty or of an actual, pending or threatened
Condemnation of the Property or any interest therein, the Lessor or the Lessee,
as the case may be, shall give notice thereof to the other and to the Agent
promptly after the receipt of such notice.

                           (d)        In the event of a
Casualty or receipt of
notice by the Lessee or the Lessor of a Condemnation, the Lessee may deliver to
the Lessor and the Agent a Termination Notice with respect to the Property
pursuant to Section 16.1. If the Lessee does not deliver a Termination
Notice within thirty (30) days after such occurrence, then this Lease shall
(subject to the terms and conditions thereof) remain in full force and effect,
and the Lessee shall, at the Lessee's sole cost and expense, promptly and
diligently restore the Property pursuant to paragraph (e) of this Section
15.1 and otherwise in accordance with this Lease.  If the Lessee delivers a Termination Notice within thirty (30)
days after such occurrence, a Significant Event shall irrevocably be deemed to
have occurred with respect to the Property, and, in such event, this Lease
shall terminate and the Lessee shall purchase the Property on the next Payment
Date (but in no event to exceed sixty (60) days after such occurrence) (a
"Termination Date") pursuant to Article XVI hereof.

                           (e)         If pursuant to this
Section 15.1
this Lease shall continue in full force and effect following a Casualty or
Condemnation, the Lessee shall, at its sole cost and expense (and, without
limitation, if any award, compensation or insurance payment is not sufficient
to restore the Property in accordance with this paragraph, the Lessee shall pay
the shortfall), promptly and diligently repair any damage to the Property
caused by such Casualty or Condemnation in conformity with the requirements of Sections
10.1 and 11.1 using the applicable as-built Plans and Specifications
for the Property (as modified to give effect to any subsequent Modifications,
any Condemnation affecting the Property and in compliance with all applicable
Requirements of Law and all Insurance Requirements) so as to restore the Property
to at least the same condition, operation, function and value as existed
immediately prior to such Casualty or Condemnation.  In the event of such restoration, title to the Property shall
remain with the Lessor; provided, that (i) title to any such substituted
equipment shall vest in the Lessor and such equipment shall constitute
Equipment thereafter for all purposes of this Lease, and (ii) the Lessor shall
assign all of its right, title and interest to the Lessee in any such replaced
equipment without representation or warranty of any kind other than that such
equipment is free of Lessor Liens and Liens created pursuant to the Operative
Documents.  Upon completion of such
restoration, the Lessee shall furnish the Lessor an architect's certificate of
substantial completion and a Responsible Officer's Certificate confirming that
such restoration has been completed pursuant to this Lease.

                           (f)         In no event shall a Casualty or
Condemnation with respect to which this Lease remains in full force and effect
under this Section 15.1 affect the Lessee's obligations to pay Rent
pursuant to Section 3.1 or to perform its obligations and pay any
amounts due on the Expiration Date or pursuant to Articles XIX and XX.

                           (g)        Any Excess Proceeds
received by the
Lessor or the Agent in respect of a Casualty or Condemnation shall be turned
over to the Lessee.

             15.2     Environmental Matters.  Promptly upon the Lessee's actual knowledge
of the presence of Hazardous Substances in any portion of the Property in
concentrations and conditions that constitute or could reasonably be expected
to constitute an Environmental Violation (excluding any such Environmental
Violation that is a Pre-Existing Environmental Condition), the Lessee shall
notify the Lessor in writing of such condition.  In the event of such Environmental Violation, the Lessee shall,
not later than thirty (30) days after the Lessee has actual knowledge of such
Environmental Violation, either, if such Environmental Violation is a Significant
Event, deliver to the Lessor and the Agent a Responsible Officer's Certificate
and a Termination Notice with respect to the Property pursuant to Section
16.1, or, if such Environmental Violation is not a Significant Event, at
the Lessee's sole cost and expense, promptly and diligently commence any
Response Actions necessary to investigate, remove, clean up or remediate such
Environmental Violation in accordance with the terms of Section 9.1.  If the Lessee does not deliver a Termination
Notice with respect to the Property pursuant to Section 16.1, the Lessee
shall, upon completion of Response Actions by the Lessee, cause to be prepared
by an environmental consultant reasonably acceptable to the Lessor a report
describing the Environmental Violation (excluding any such Environmental Violation
that is a Pre-Existing Environmental Condition) and the Response Actions taken
by the Lessee (or its agents or contractors) for such Environmental Violation,
and a statement by the consultant that such Environmental Violation (excluding
any such Environmental Violation that is a Pre-Existing Environmental
Condition) has been remedied in compliance in all material respects with
applicable Environmental Law.  Each such
Environmental Violation shall be remedied prior to the Expiration Date.  Nothing in this Article XV shall
reduce or limit the Lessee's obligations under Sections 13.1, 13.2 or 13.3 of
the Participation Agreement.

             15.3     Notice of Environmental Matters.  Promptly, but in any event within thirty
(30) Business Days from the date the Lessee has actual knowledge thereof, the
Lessee shall provide to the Lessor written notice of any material pending or
threatened claim, action or proceeding involving any Environmental Law or any
Release on or in connection with the Property (other than with respect to any
Pre-Existing Environmental Condition). 
All such notices shall describe in reasonable detail the nature of the
claim, action or proceeding and the Lessee's proposed response thereto.  In addition, the Lessee shall provide to the
Lessor, within thirty (30) Business Days of receipt, copies of all material
written communications with any Governmental Authority relating to any
Environmental Law in connection with the Property.  The Lessee shall also promptly provide such detailed reports of
any such material environmental claims (other than with respect to any
Pre-Existing Environmental Condition) as may reasonably be requested by the
Lessor and the Agent.

ARTICLE XVI.

             16.1     Termination by the Lessee upon Certain Events.  If either: (i) the Lessee or the Lessor
shall have received notice of a Condemnation, and the Lessee shall have
delivered to the Lessor a Responsible Officer's Certificate that such
Condemnation is a Significant Condemnation; or (ii) a Casualty occurs, and the
Lessee shall have delivered to the Lessor a Responsible Officer's Certificate
that such Casualty is a Significant Casualty; or (iii) an Environmental
Violation occurs or is discovered and the Lessee shall have delivered to the
Lessor a Responsible Officer's Certificate stating that, in the reasonable,
good-faith judgment of the Lessee, the cost to remediate the same will cause
the same to be a Significant Event, or (iv) if the Lessee shall not have
delivered a Termination Notice with respect to such Environmental Violation
described in clause (iii) but the requirements of Section 16.3
are met with respect to such Environmental Violation; then, (A) the Lessee
shall, simultaneously with the delivery of the Responsible Officer's
Certificate pursuant to the preceding clause (i), (ii) or (iii)
deliver a written notice in the form described in Section 16.2(a) (a
"Termination Notice"), or (B) if clause (iv) is
applicable, the Lessor may deliver a Termination Notice pursuant to Section
16.3.

             16.2     
Procedures.

                           (a)         A Termination
Notice shall contain: (i)
notice of termination of this Lease with respect to the Property or the
affected portion thereof on a date that is no later than sixty (60) days after
the occurrence of the applicable event described in clause (i), (ii)
or (iii) of Section 16.1 (the "Termination Date"),
such termination to be effective upon the Lessee's payment of the Asset
Termination Value (or portion thereof representing the Property Cost of the
affected portion of the Property); and (ii) a binding and irrevocable agreement
of the Lessee to pay the Asset Termination Value and purchase the Property on
the Termination Date.

                           (b)        On the Termination Date,
the Lessee
shall pay to the Lessor the Asset Termination Value (or such portion thereof,
as applicable), plus all other amounts owing in respect of Rent for the
Property (including Supplemental Rent) theretofore accruing, and the Lessor
shall convey the Lessor's interest in the Property or such portion thereof to
the Lessee (or the Lessee's designee) all in accordance with Section 19.1
and, to the extent applicable, Section 19.2, as well as any Net Proceeds
with respect to the Casualty or Condemnation giving rise to the termination of
this Lease with respect to the Property theretofore received by the Lessor.

             16.3     
Purchase of Property.  Upon receipt of any notice pursuant to Section
15.2 or 15.3, the Lessor or the Required Participants, at the
Lessee's expense, shall have the right to select an independent environmental
consultant acceptable to the Lessee, which acceptance shall not be unreasonably
withheld or delayed, to determine the estimated cost of conducting any clean-up
or remediation required as a result of the Environmental Violation disclosed in
such notice.  If such independent environmental
consultant determines that the cost of any such clean-up or remediation would
exceed thirty percent (30%) of the original Property Cost, the Lessor shall, at
the direction of the Required Participants, by written notice require the
Lessee to purchase, or arrange for an Affiliate of Lessee or other third party
to purchase, the Property on the Termination Date by delivering a Termination
Notice following the requirements of Section 16.2 hereof.

continuing, do one or more of the following as the Lessor in its sole
discretion shall determine, without limiting any other right or remedy the

limitation, the obligation of the Lessee to purchase the Property as set forth
in Section 20.3):

                           (a)         The Lessor may, by
notice to the
Lessee, terminate the Commitments and rescind or terminate this Lease as to all
or any portion of the Property as of the date specified in such notice;
however, (i) no reletting, reentry or taking of possession of the Property (or
any portion thereof) by the Lessor will be construed as an election on the
Lessor's part to terminate this Lease unless a written notice of such intention
is given to the Lessee, (ii) notwithstanding any reletting, reentry or taking
of possession, the Lessor may at any time thereafter elect to terminate this
Lease for a continuing Event of Default, and (iii) no act or thing done by the
Lessor or any of its agents, representatives or employees and no agreement
accepting a surrender of the Property shall be valid unless the same be made in
writing and executed by the Lessor;

                           (b)        The Lessor may (i)
demand that the
Lessee, and the Lessee shall upon the written demand of the Lessor, return the
Property promptly to the Lessor in the manner and condition required by, and
otherwise in accordance with all of the provisions of, Articles VIII, IX
and X hereof as if the Property were being returned at the end of the
Term, and the Lessor shall not be liable for the reimbursement of the Lessee
for any costs and expenses incurred by the Lessee in connection therewith and
(ii) without prejudice to any other remedy which the Lessor may have for
possession of the Property, and to the extent and in the manner permitted by
Applicable Law, enter upon the Property and take immediate possession of (to
the exclusion of the Lessee) the Property or any part thereof and expel or
remove the Lessee and any other Person who may be occupying the Property, by
summary proceedings or otherwise, all without liability to the Lessee for or by
reason of such entry or taking of possession, whether for the restoration of
damage to property caused by such taking or otherwise and, in addition to the
Lessor's other damages, the Lessee shall be responsible for all costs and
expenses incurred by the Lessor or the Participants in connection with any
reletting, including, without limitation, brokers' fees and all costs of any
alterations or repairs made by the Lessor;

any part
of the Property at public or private sale, as the Lessor may determine,
pursuant to such notices and procedures as may be required by Applicable Law,
free and clear of any rights of the Lessee and without any duty to account to
the Lessee with respect to such action or inaction or any proceeds with respect
thereto (except to the extent required by clause (ii) below if the
Lessor shall elect to exercise its rights thereunder) in which event the
Lessee's obligation to pay Basic Rent hereunder for periods commencing after
the date of such sale shall be terminated or proportionately reduced, as the
case may be; and (ii) if the Lessor shall so elect, demand that the Lessee pay
to the Lessor, and the Lessee shall pay to the Lessor, on the date of such
sale, as liquidated damages for loss of a bargain and not as a penalty (the
parties agreeing that the Lessor's actual damages would be difficult to
predict, but the aforementioned liquidated damages represent a reasonable
approximation of such amount) (in lieu of Basic Rent due for periods commencing
on or after the Payment Date coinciding with such date of sale (or, if the sale
date is not a Payment Date, the Payment Date next preceding the date of such
sale)), an amount equal to (A) the excess, if any, of (1) the Asset Termination
Value calculated as of such Payment Date (including all Rent due and unpaid to
and including such Payment Date) less the aggregate amount of the Cash
Collateral, if any, retained by the Lessor, the Agent or the Participants, over
(2) the net proceeds of such sale, if any (that is, after deducting all costs
and expenses incurred by the Lessor, the Agent and the Participants incident to
such conveyance, including, without limitation, repossession costs, brokerage
commissions, prorations, transfer taxes, fees and expenses for counsel, title
insurance fees, survey costs, recording fees, and any repair or alteration
costs); plus (B) interest at the Overdue Rate on the foregoing amount from such
Payment Date until the date of payment; provided, that the Lessor shall
deliver all proceeds from the sale of the Property and other amounts received
hereunder, including any Cash Collateral, to the Agent for application as
provided in Sections 3.14, 3.17 and 3.18 of the Participation Agreement.

                           (d)        Reserved;

                           (e)         Unless the
Property has been sold in
its entirety, the Lessor may, subject to Section 17.2(h), whether or not
the Lessor shall have exercised or shall thereafter at any time exercise any of
its rights under paragraph (b), (c) or (i) of this Section
17.2 with respect to the Property or portions thereof, demand, by written
notice to the Lessee specifying a date (a "Termination Date")
not earlier than 10 days after the date of such notice, that the Lessee
purchase, on such Termination Date, the Property (or the remaining portion
thereof) in accordance with the provisions of Article XIX and Section
20.3;

                           (f)         The Lessor may exercise any
other right
or remedy that may be available to it under the Operative Documents or
otherwise under Applicable Law, or proceed by appropriate court action (legal
or equitable) to enforce the terms hereof or to recover damages for the breach
hereof.  Separate suits may be brought
to collect any such damages for any period(s), and such suits shall not in any
manner prejudice the Lessor's right to collect any such damages for any
subsequent period(s), or the Lessor may defer any such suit until after the
expiration of the Term, in which event such suit shall be deemed not to have
accrued until the expiration of the Term;

                           (g)        The Lessor may retain
and apply against
the Lessor's damages all sums which the Lessor would, absent such Event of
Default, be required to pay to, or turn over to, the Lessee pursuant to the
terms of this Lease;

                           (h)        Notwithstanding anything
contained in
this Lease or any other Operative Document to the contrary, in the event that
the Event of Default resulting in the exercise of remedies by the Lessor hereunder
is solely a Limited Event of Default, then the following provisions of this Section
17.2(h) shall apply (but without limitation of the right and remedies set
forth in Section 17.2(a)).  The
Lessee shall have the option or, if the Lessor terminates this Lease, the
Lessee shall be required to elect to (i) remarket the Property for 180
days after the occurrence of such Limited Event of Default in accordance with Article
XXII hereof (which period shall constitute the Marketing Period), with the
purchase of the Property to be consummated no later than the date that is 180
days following the occurrence of such Limited Event of Default (which date
shall constitute the Expiration Date if such option is exercised or required to
be exercised), or (ii) exercise its Purchase Option under Section 20.1
hereof, with the purchase of the Property by the Lessee to be consummated, and
the other payments required thereunder to be made to the Lessor, on the next
Payment Date following the occurrence of such Limited Event of Default (which
date shall constitute the Expiration Date if such option is exercised).  Notwithstanding the provisions of clause
(i) above, if the Lessor elects to terminate the Lease solely due to the
occurrence of a Limited Event of Default and (x) the Lessor delivers to the
Lessee an appraisal of the Property prepared by an appraiser selected by the
Lessor and reasonably satisfactory to the Agent, the Required Participants and
the Lessee setting forth the Fair Market Sales Value of the of the Property as
of the date of the occurrence of such Limited Event of Default, and (y) the sum
of the Fair Market Sales Value of the Property set forth in such report plus
the maximum Residual Value Guarantee Amount then payable by the Lessee in
connection with the exercise of the Remarketing Option is less than the Asset
Termination Value as of such date, then and in such event the Lessee shall not
be entitled to elect to exercise the Remarketing Option and the Lessor may in
lieu thereof require the Lessee to elect to either (A) return the Property
promptly to the Lessor in the manner and condition required by, and otherwise
in accordance with all of the provisions of, Articles VIII, IX
and X hereof as if the Property were being returned at the end of the
Term, or (B) exercise its Purchase Option under Section 20.1 hereof,
with the purchase of the Property by the Lessee to be consummated, and the
other payments required thereunder to be made to the Lessor, on the next
Payment Date following the occurrence of such Limited Event of Default (which
date shall constitute the Expiration Date if such option is exercised).  The Lessee shall notify the Lessor within
ten (10) days after the occurrence of such Limited Event of Default which option
it is exercising.  If the Lessee elects
to remarket the Property pursuant to clause (i) above or elects to
return the Property pursuant to clause (A) above, the Lessee shall pay
to the Lessor (i) the maximum Residual Value Guarantee Amount on the date the
Lessee furnishes such notice of exercise of the Remarketing Option or such
notice of its election to return the Property in accordance with clause (A)
above (or, if the Lessor elects, on the date that is ten (10) days after the
Lessor furnishes the Lessee notice that it will require the Lessee to remarket
or purchase the Property or return or purchase the Property, as the case may
be), (ii) Basic Rent when due for the duration of the 180 day Marketing Period,
in the case of an exercise of the Remarketing Option, or all accrued and unpaid
Basic Rent as of the date of the return of the Property in accordance with clause
(A) above, in the case of a return of the Property, and (iii) in the case
of an exercise of the Remarketing Option, the other payments required under Section
22.1 when required thereunder and no later than the Expiration Date.

                           (i)          In addition to the other
rights and
remedies set forth herein, the Lessor shall have the right to continue this
Lease in effect and, as permitted by Section 1951.4 of the California Civil
Code, to enforce, by suit or otherwise, all covenants and conditions hereof to
be performed or complied with by the Lessee and exercise all of the Lessor's
rights and remedies under this Lease, including, without limitation, the right
to recover Basic Rent and Supplemental Rent from the Lessee as it becomes due
under this Lease, even though the Lessee shall have breached this Lease and
abandoned the Property.  Acts of
maintenance or preservation, or efforts by the Lessor or on the Lessor's behalf
to relet the Property, or the appointment of a receiver upon the initiative of
the Lessor to protect the Lessor's interest under this Lease shall not
constitute a termination of the Lessee's right to possession of the Property; provided,
however, that the foregoing enumeration shall not be construed as in any
way limiting the actions the Lessor may take without terminating the Lessee's
right to possession.  In furtherance of
the rights hereby granted to the Lessor, and to the extent permitted by law,
the Lessee hereby appoints the Lessor its agent and attorney–in–fact,
which appointment shall be deemed to be coupled with an interest and is
irrevocable, with power of substitution, to enter the Property upon a Event of
Default hereunder and remove therefrom all persons and property (with the right
to store such property on the Property in a public warehouse or elsewhere at
the cost and risk and for the account of the Lessee) and to alter the Property
in such manner as the Lessor may deem necessary or advisable so as to put the Property
in good order and to make the same rentable and from time to time and sublet
the Property or any part thereof for such term or terms whether or not
extending beyond the then current term of this Lease (but such sublease may
provide for a new and successive lease to commence immediately upon the
termination of this Lease), at such rentals and upon such other terms as the
Lessor in its sole discretion may deem advisable, and with the right to make
alterations and repairs to the Property; and the Lessee agrees to pay to the
Lessor on demand all expenses incurred by the Lessor in such subletting, and in
altering, repairing and putting the Property in good order and condition, and
in reletting the same, including fees of attorneys and architects, and all other
expenses or commissions.  The Lessor
shall be the Lessee's agent and representative on the Property in respect of
all matters arising under or in connection with any such sublease made for the
Lessee by the Lessor.  Under each such
sublease, the Lessee shall retain the right to enter upon and use the Property,
subject to the terms and conditions of such sublease and the rights of the
sublessee thereunder.  The Lessee
further agrees to pay to the Lessor, following the date of such subletting, to
and including the date provided in this Lease for the expiration of the Term,
the sums of money which would have been payable by the Lessee as Basic Rent and
Supplemental Rent, deducting only the net amount of rent, if any, which the
Lessor shall actually receive (after deducting from the gross receipts the
expenses, costs and payments of the Lessor which in accordance with the terms
of this Lease would have been borne by the Lessee) in the meantime from and by
any such subletting of the Property, and the Lessee hereby agrees to remain
liable for all sums otherwise payable by the Lessee under this Lease,
including, but not limited to, the expenses of the Lessor aforesaid, as well as
for any deficiency aforesaid.  The
Lessor shall have the right from time to time to begin and maintain successive
actions or other legal proceedings against the Lessee for the recovery of such
deficiency, expenses or damages or for a sum equal to any installments of Basic
Rent or Supplemental Rent and other sums payable hereunder, and to recover the
same upon the liability of the Lessee herein provided, which liability it is
expressly covenanted shall survive the commencement or determination of any
action to secure possession of the Property. 
Nothing herein contained shall be deemed to require the Lessor to wait
to begin such action or other legal proceedings until the date when this Lease
would have expired by limitation had there been no such Event of Default.  Notwithstanding any such subletting without
termination, pursuant to the terms hereof, the Lessor shall retain the right to
and may at any time thereafter elect to terminate this Lease or the Lessee's
right to possession of the Property for any previous breach which remains
uncured or for any subsequent breach by giving the Lessee written notice
thereof as herein provided, and in such event the Lessee shall forfeit any
rights or interest under any such sublease and thereafter the obligations of
any such sublessee shall run directly to the Lessor for its own account.  Upon application by the Lessor, a receiver
may be appointed to take possession of the Property, exercise all rights
granted to the Lessor as agent and attorney–in–fact for the Lessee
set forth in this Section 17.2(i) and apply any rentals collected from
the Property as hereinabove provided. 
No taking of possession of the Property or other act by the Lessor as
the agent and attorney–in–fact for the Lessee pursuant to the
foregoing provisions, nor any subletting by the Lessor for the Lessee pursuant
to the foregoing provisions, nor any such appointment of a receiver shall
constitute or be construed as an election by the Lessor to terminate this Lease
or the Lessee's right to possession of the Property unless a written notice of
such intention be given to the Lessee.

                           (j)          If this Lease is being
terminated on
the basis of the occurrence of an Event of Default (excluding a Limited Event
of Default) arising out of the failure to perform an obligation or covenant
listed on Schedule 17.2(j) or the breach of a representation or warranty
listed on Schedule 17.2(j), or the performance of which covenant or
obligation or the truth of which representation or warranty, or otherwise the
existence of such Event of Default (excluding a Limited Event of Default), is
qualified by the words "material," or "Objective Material
Adverse Effect" (but not "Material Adverse Effect") or "in
all material respects" or another similar qualifier set forth on Schedule
17.2(j) hereto, Lessor shall, to the extent required by Schedule 17.2(j)
hereto, apply commercially reasonable standards in determining that such Event
of Default (excluding a Limited Event of Default) occurred.

                           (k)         In the event a
Limited Event of Default
occurs prior to the Land Interest Acquisition Date in respect of the Phase II
Facility and the Lessor is exercising its rights and remedies under Section
17.2(h) with respect thereto, Lessor shall, in addition to such rights and
remedies, be entitled to take such steps as it may deem necessary or
appropriate to, and may require the Lessee to use its best efforts to, identify
a Person willing to accept an assignment of the Property Purchase Agreement in
respect of the Phase II Facility and to consummate the purchase of the Phase II
Facility.  In the event such a Person is
identified, the Lessee shall (i) cooperate with the Lessor and such Person as
necessary or as requested in order to transfer to such Person the rights and
benefits of the Lessee and/or the Lessor under the Property Purchase Agreement
and the Lockheed Indemnification Agreements in respect of the Phase II
Facility, and (ii) pay for any modifications requested by such Person to the
relevant Plans and Specifications and for any fees, costs or expenses required
to be paid or reimbursed to such Person in connection with such Person's
agreement to so acquire the Phase II Facility provided the Lessee's
liability with respect thereto shall not exceed 89.9% of the purchase price in
respect of the Phase II Facility payable pursuant to the Property Purchase
Agreement.

             17.3     Waiver of Certain Rights.  If this Lease shall be terminated pursuant
to Section 17.2, the Lessee waives, to the fullest extent permitted by
law, (a) any notice of re-entry or the institution of legal proceedings to
obtain re-entry or possession; (b) any right of redemption, re-entry or
repossession; (c) the benefit of any laws now or hereafter in force exempting
property from liability for rent or for debt or limiting the Lessor with
respect to the election of remedies; and (d) any other rights which might
otherwise limit or modify any of the Lessor's rights or remedies under this Article
XVII.

             17.4     
Loan Remedies.
If the transaction evidenced by this Agreement and the other Operative
Documents is treated as a loan, upon the occurrence or existence of any Event
of Default and at any time thereafter unless such Event of Default is waived,
the Lessor and the Trustee may with the consent of the Required Participants,
or shall, upon instructions from the Required Participants, exercise any one or
more of the following rights and remedies in addition to those rights and
remedies set forth in Section 17.2:

                           (a)         Acceleration of
Obligations.  The Lessor may, by written notice to the
Lessee, terminate this Lease and declare all unpaid Obligations due and
payable.  On such termination date
(which shall then be the Expiration Date), the Lessee shall pay the Asset
Termination Value (subject to Section 17.2(h)), all unpaid Basic Rent
accrued through such date, all Supplemental Rent due and payable on or prior to
such date and all other amounts payable by the Lessee on the Expiration Date
pursuant to this Lease and the other Operative Documents.

                           (b)        Uniform Commercial
Code Remedies.  The Lessor may exercise any or all of the
remedies granted to a secured party under the California Uniform Commercial
Code.

                           (c)         Judicial
Foreclosure.  The Lessor may bring an action in any court
of competent jurisdiction to foreclose the security interest in the Property
granted to the Lessor by this Lease or any of the other Operative Documents; provided
that if the Event of Default resulting in an exercise of such remedy is solely
a Limited Event of Default, the Lessor's right to recover any deficiency amount
from the Lessee following any such foreclosure shall be limited as set forth in
Section 17.2(h).  Further, Lessor
and/or the Trustee may bring an action or actions in a court of competent
jurisdiction to foreclose this instrument as a mortgage and to obtain specific
enforcement of the covenants of the Lessee hereunder, and the Lessee agrees
that such covenants shall be specifically enforceable by injunction or any
other appropriate equitable remedy and that for the purposes of any suit
brought hereunder the Lessee waives the defense of laches and any applicable
statute of limitations.

                           (d)        Power of Sale
 .  The Lessor may cause some or all of the
Property including any Collateral constituting personal property, including the
Cash Collateral ("Personal Property Collateral"), to be sold
or otherwise disposed of in any combination and in any manner permitted by
Applicable Law.

                           (i)          Sales of
Personal Property.  The Lessor may dispose of any Personal
Property Collateral separately from the sale of the Collateral constituting
real property ("Real Property Collateral"), in any manner
permitted by Division 9 of the California Uniform Commercial Code, including
any public or private sale, or in any manner permitted by any other applicable
Governmental Rule.  Any proceeds of any
such disposition shall not cure any Event of Default or reinstate any
Obligation for purposes of Section 2924c of the California Civil Code.  In connection with any such sale or other
disposition, the Lessee agrees that the following procedures constitute a
commercially reasonable sale:

                           (A)       The Lessor shall mail written
notice of
the sale to the Lessee not later than thirty (30) days prior to such sale.

                           (B)        Once per week during the
three (3) weeks
immediately preceding such sale, the Lessor will publish notice of the sale in
a local daily newspaper of general circulation.

                           (C)        Upon receipt of any
written request, the
Lessor will make the Property available to any bona fide prospective purchaser
for inspection during reasonable business hours.

                           (D)        Notwithstanding, the
Lessor shall be
under no obligation to consummate a sale if, in its judgment, none of the
offers received by it equals the fair value of the Property offered for sale.

                           (E)        If the Lessor so
requests, the Lessee
shall assemble all of the Personal Property Collateral and make it available to
the Lessor at the site of the Land Interest. 
Regardless of any provision of this Agreement or any other Operative
Document, the Lessor shall not be considered to have accepted any property
other than cash or immediately available funds in satisfaction of any
Obligation, unless the Lessor has given express written notice of its election
of that remedy in accordance with California Uniform Commercial Code Section
9505.

The
foregoing procedures do not constitute the only procedures that may be
commercially reasonable.

                           (ii)         Lessor's Sales
of Real Property or
Mixed Collateral.  The Lessor may
choose to dispose of some or all of the Property which consists solely of Real
Property Collateral in any manner then permitted by Applicable Law, including
without limitation a nonjudicial trustee's sale pursuant to California Civil
Code §§2924 et seq.  In
its discretion, the Lessor may also or alternatively choose to dispose of some
or all of the Property, in any combination consisting of both Real Property
Collateral and Personal Property Collateral, together in one sale to be held in
accordance with the law and procedures applicable to real property, as
permitted by Section 9501(4) of the California Uniform Commercial Code.  The Lessee agrees that such a sale of
Personal Property Collateral together with Real Property Collateral constitutes
a commercially reasonable sale of the Personal Property Collateral.  (For purposes of this Power of Sale, either
a sale of Real Property Collateral alone, or a sale of both Real Property
Collateral and Personal Property Collateral together in accordance with
California Uniform Commercial Code Section 9501(4), will sometimes be referred
to as a "Lessor's Sale").

                           (A)       Before any Lessor's Sale, the
Lessor
shall give such notice of default and election to sell as may then be required
by Applicable Law.

                           (B)        When all time periods
then legally
mandated have expired, and after such notice of sale as may then be legally
required has been given, the Lessor shall sell the property being sold at a
public auction to be held at the time and place specified in the notice of
sale.

                           (C)        Neither the Lessor nor
the Agent shall
have any obligation to make demand on the Lessee before any Lessor's Sale.

                           (D)        From time to time in
accordance with
then Applicable Law, the Lessor may postpone any Lessor's Sale by public
announcement at the time and place noticed for that sale.

                           (E)        At any Lessor's Sale,
the Lessor shall
sell to the highest bidder at public auction for cash in lawful money of the
United States.

                           (F)        The Lessor shall execute
and deliver to
the purchaser(s) a deed or deeds conveying the Property being sold without any
covenant or warranty whatsoever, express or implied.  The recitals in any such deed of any matters or facts, including
any facts bearing upon the regularity or validity of any Lessor's Sale, shall
be conclusive proof of their truthfulness. 
Any such deed shall be conclusive against all Persons as to the facts
recited in it.

                           (e)         Foreclosure Sales.

                           (i)          Single or
Multiple.  If the Property consists of more than one
lot, parcel or item of property, Lessor may:

                           (A)       Designate the order in which
the lots,
parcels and/or items shall be sold or disposed of or offered for sale or
disposition; and

                           (B)        Elect to dispose of the lots, parcels
and/or items through a single consolidated sale or disposition to be held or
made under the power of sale granted in Section 17.4(d), or in
connection with judicial proceedings, or by virtue of a judgment and decree of
foreclosure and sale; or through two or more such sales or dispositions; or in
any other manner the Lessor may deem to be in its best interests (any such sale
or disposition, a "Foreclosure Sale," any two or more, "Foreclosure
Sales").

If
the Lessor chooses to have more than one Foreclosure Sale, the Lessor at its option
may cause the Foreclosure Sales to be held simultaneously or successively, on
the same day, or on such different days and at such different times and in such
order as it may deem to be in its best interests.  No Foreclosure Sale shall terminate or affect the security
interests granted to the Lessor in the Property by this Lease or any part of
the Property which has not been sold, until all of the Obligations have been
paid in full.

                           (ii)         Credit Bids
 .  At any Foreclosure Sale, any Person,
including the Lessor or any Participant, may bid for and acquire the Property
or any part of it to the extent permitted by Applicable Law.  Instead of paying cash for the Property, the
Lessor may settle for the purchase price by crediting the sales price of the
Property against the Obligations in any order and proportions as the Lessor in
its sole discretion may choose.

                           (f)         Additional Rights
and Remedies.

                           (i)          In addition
to and without limitation
of the rights and remedies otherwise provided in this Section 17.4, Lessor
or its employees, acting by themselves or through a court-appointed receiver,
may enter upon, possess, manage, operate, dispose of and contract to dispose of
the Property or any part thereof; negotiate with governmental authorities with
respect to the Property's environmental compliance and remedial measures;
contract for goods and services, hire agents, employees and counsel, make
repairs, alterations and improvements to the Property necessary, in Lessor's
judgment, to protect or enhance the security hereof; to incur the risks and
obligations ordinarily incurred by owners of property (without any personal
obligation on the part of the receiver); and/or to take any and all other
actions which may be necessary or desirable to comply with Lessee's obligations
hereunder and under the Operative Documents. 
All sums realized by the Lessor under this Section 17.4(f)(i),
less all costs and expenses incurred by it under this Section 17.4(f)(i),
including attorneys' fees, and less such sums as the Lessor deems appropriate
as a reserve to meet future expenses under this Section 17.4(f)(i),
shall be applied to any Obligations secured hereby in such order as the Lessor
shall determine.  Neither application of
said sums to said indebtedness nor any other action taken by the Lessor under
this Section 17.4(f)(i) shall cure or waive any Event of Default or
notice of default hereunder or nullify the effect of any such notice of
default.  The Lessor, or any employee or
agent of the Lessor, or a receiver appointed by a court, may take any action or
proceeding hereunder without regard to (i) the adequacy of the security for the
indebtedness secured hereunder, (ii) the existence of a declaration that the
indebtedness secured hereby has been declared immediately due and payable, or
(iii) the filing of a notice of default;

                           (ii)         Lessor shall have the power and
authority to execute a written notice of such Event of Default and, at its
election, cause the Property to be sold to satisfy the Obligations secured
hereby.  The Lessor shall give and
record such notice as the law then requires as a condition precedent to a
nonjudicial foreclosure sale.  When the
minimum period of time required by law after such notice has elapsed, the
Lessor, without notice to or demand upon Lessee except as otherwise required by
law, shall sell the Property at the time and place of sale fixed by it in the
notice of sale and in such order as it or the Lessor may determine, at public
auction to the highest bidder for cash in lawful money of the United States,
payable at time of sale (the Obligations hereby secured being the equivalent of
cash for purposes of said sale).  If the
Property consists of several lots, parcels, or items of property, the Lessor
may: (i) designate the order in which such lots, parcels, or items of property
shall be offered for sale or sold, or (ii) elect to sell such lots, parcels or
items through a single sale, through two or more successive sales, or in any
other manner the Lessor deems in its best interest.  The Lessee shall have no right to direct the order in which the
Property is sold.  The Lessor may
postpone sale of all or any portion of the Property by public announcement at
such time and place of sale, and from time to time thereafter may postpone such
sale by public announcement at such time fixed by the preceding
postponement.  The Lessor shall deliver
to the purchaser at such sale a deed or other appropriate transfer instrument
conveying the Property or portion thereof so sold, but without any covenant or
warranty, express or implied.  The
recitals in such deed of any matters of facts shall be conclusive proof of the
truthfulness thereof.  Any person,
including the Lessor or the Lessee may purchase at such sale.

             In connection with any sale or
sales hereunder, the Lessor may elect to treat any of the Property which
consists of a right in action or which is property that can be severed from the
real property covered hereby or any improvements thereon without causing
structural damage thereto as if the same were personal property or a fixture,
as the case may be, and dispose of the same in accordance with applicable law,
separate and apart from the sale of real property.  Any sale of any personal property or fixtures hereunder shall be
conducted in any manner permitted by the California Uniform Commercial Code.

             After deducting all costs, fees and
expenses of the Lessor and of this trust, including all costs of evidence of
title and attorneys' fees in connection with sale, the Lessor shall apply the
proceeds of sale to payment of all sums so expended under the terms hereof not
then repaid; the payment of all other sums then secured hereby; and the
remainder, if any, to the person or persons legally entitled thereto;

                           (iii)        Lessor shall have the power and
authority to resort to and realize upon the Property and any other security now
or hereafter held by the Lessor in such order and manner as the Lessor and the
Trustee may, in their sole discretion, determine; and resort to any or all such
security may be taken concurrently or successively and in one or several
consolidated or independent judicial actions or lawfully taken non-judicial
proceedings, or both.

             17.5     
Remedies Cumulative.  The remedies herein provided shall be
cumulative and in addition to (and not in limitation of) any other remedies
available at law, equity or otherwise, including, without limitation, any
mortgage foreclosure remedies.

             17.6     The Lessee's Right to Cure.  Notwithstanding any provision contained in
the Lease or any other Operative Document, if a Event of Default has occurred
and is continuing, the Lessee shall have the right to cure such Event of
Default by (a) exercising its Purchase Option at any time prior to the earlier
of (i) the termination of the Lessee's possessory interest in the Property, (ii)
the thirty day period following the occurrence of a Lease Event of Default and
(iii) the entering into by the Lessor of a binding contract to sell the
Property, and (b) purchasing the Property in accordance with Section 20.1
at any time prior to such time as a foreclosure upon or sale of the Property
has been completed.

ARTICLE XVIII.

             18.1     The Lessor's Right to Cure the Lessee's Defaults.  The Lessor, without waiving or releasing any
obligation or Event of Default, may (but shall be under no obligation to)
remedy any Default or Event of Default (other than a Limited Default or a
Limited Event of Default) for the account and at the sole cost and expense of
the Lessee, including the failure by the Lessee to maintain the insurance
required by Article XIV (subject to the limitations set forth in Section
24.1), and may, to the fullest extent permitted by law, and notwithstanding
any right of quiet enjoyment in favor of the Lessee, enter upon the Property
for such purpose and take all such action thereon as may be necessary or
appropriate therefor.  No such entry
shall be deemed an eviction of the Lessee. 
All out-of-pocket costs and expenses so incurred (including fees and
expenses of counsel), together with interest thereon at the Overdue Rate from
the date on which such sums or expenses are paid by the Lessor, shall be paid
by the Lessee to the Lessor on demand (subject to the limitations set forth in Section
24.1), as Supplemental Rent.

ARTICLE XIX.

             19.1     Provisions Relating to the Lessee's Termination of this Lease
or Exercise of Purchase Option or Obligation and Conveyance Upon Remarketing
and Conveyance Upon Certain Other Events.

                           (a)         In connection with
any termination of
this Lease pursuant to the terms of Section 16.2 or 16.3 (if the
Lessee is obligated to purchase the Property), or in connection with the
Lessee's exercise of its Purchase Option or Expiration Date Purchase
Obligation, upon the date on which this Lease is to
terminate or upon the Expiration Date, and upon tender by the Lessee of the
amounts set forth in Sections 16.2(b), 20.1, 20.2 or 20.3,
as applicable, the Lessor shall execute and deliver to the Lessee (or to the
Lessee's designee) at the Lessee's cost and expense an assignment or transfer
without recourse of the Lessor's right, title and interest in the Property
(which shall include a release, quitclaim and assignment of all of the Lessor's
right, title and interest in and to any Net Proceeds with respect to the
Property or such portion thereof not previously received by the Lessor), subject
to Permitted Exceptions (other than Lessor Liens and, so long as all amounts
required to be paid upon such termination or exercise have been paid and
discharged in full, free of all Liens created by the Operative Documents) and
any encumbrance caused by the fault, neglect or intention of the Lessee, in
recordable form and otherwise in conformity with local custom and free and
clear of any Lessor Liens.  The
Improvements and the Equipment shall be conveyed to the Lessee "AS
IS" and in their then present condition of title and physical condition
free of any Lessor Liens and, so long as all amounts required to be paid upon
such termination or exercise have been paid and discharged in full, free of all
Liens created by the Operative Documents.

                           (b)        If the Lessee properly
exercises the
Remarketing Option or is required to remarket the Property or return the
Property to the Lessor pursuant to Section 17.2(h), then the Lessee
shall, on the Expiration Date, transfer possession of the Property (or
remaining portion thereof) to the Lessor or the independent purchaser thereof,
as the case may be, by surrendering the same into the possession of the Lessor
or such purchaser, as the case may be, free and clear of all Liens other than
Lessor Liens, in good condition (as modified by Modifications permitted by this
Lease), ordinary wear and tear excepted, in compliance with Applicable Law, and
in "broom-swept clean" condition. 
The Lessee shall cooperate reasonably with the Lessor and the
independent purchaser of the Property (or remaining portion thereof) in order
to facilitate the purchase by such purchaser of the Property (or remaining
portion thereof) which cooperation shall include the following, all of which
the Lessee shall do on or before the Expiration Date: providing all books and
records regarding the maintenance and ownership of the Property (or remaining
portion thereof) and all know–how, data and technical information
relating thereto, providing a current copy of all of the "as built"
Plans and Specifications for the Property, granting or assigning (to the extent
assignable) all existing licenses necessary for the operation and maintenance
of the Property and cooperating reasonably in seeking and obtaining all
necessary Governmental Action and complying with the provisions of Section
22.3 hereof.  The obligations of the
Lessee under this paragraph shall survive the expiration or termination of this
Lease. The reasonable, customary and documented costs and expenses of the
Lessee in complying with this Section 19.1(b) shall at the request of
the Lessee be paid or reimbursed from the gross proceeds of a sale of the
Property.

ARTICLE XX.

             20.1     
Purchase Option.
Without limitation of the Lessee's purchase obligation pursuant to Sections
20.2 or 20.3, unless the Lessee shall have given notice of its
intention to exercise the Remarketing Option and the Lessor shall have entered
into a binding contract to sell the Property, the Lessee shall have the option
(exercisable by giving the Lessor irrevocable written notice (each, a "Purchase
Notice") of the Lessee's election to exercise such option) to
purchase, or to designate a third party to purchase, all of the Property (the
"Purchase Option"), on the date specified in such Purchase
Notice, which date shall be a Payment Date. 
The purchase price in respect of the Property (the "Purchase
Option Price") shall be equal to the Asset Termination Value plus in
each case all other amounts owing in respect of Rent (including Supplemental
Rent) theretofore accruing (offsetting against such amount the aggregate amount
of the Cash Collateral, if any).  The
Lessee shall deliver the Purchase Notice to the Lessor not less than thirty
(30) days prior to the purchase date. 
If the Lessee exercises its Purchase Option pursuant to this Section
20.1 (the "Purchase Option"), the Lessor shall transfer to
the Lessee all of the Lessor's right, title and interest in and to all of the
Property, as of the date specified in the Purchase Notice upon receipt of the
Purchase Option Price and (without duplication) all Rent and all other amounts
then due and payable under this Lease and any other Operative Document, in
accordance with Section 19.1(a).

             20.2     Expiration Date Purchase Obligation.
Unless (a) the Lessee shall have properly exercised the Purchase Option
pursuant to Section 20.1 and purchased the Property pursuant thereto,
(b) the Lessee shall have properly exercised the Remarketing Option and shall
have fulfilled all of the conditions of clauses (a) through (j)
and (m) of Section 22.1 hereof, or (c) the Lessee shall have
properly exercised the Renewal Option pursuant to Section 21.1 and the
terms and conditions of a Renewal Term shall have been agreed upon pursuant to
such Section, then, subject to the terms, conditions and provisions set forth
in this Section 20.2, and in accordance with the terms of Section
19.1(a), the Lessee shall purchase from the Lessor, and the Lessor shall
assign and convey to the Lessee without recourse, on the Expiration Date of the
Term (as such Term may be renewed pursuant to Section 21.1) all of the
Lessor's right, title and interest in the Property for an amount equal to the
Asset Termination Value (the "Expiration Date Purchase Obligation"),
offsetting against such amount the aggregate amount of the Cash Collateral, if
any.  The Lessee may designate, in a
notice given to the Lessor not less than ten (10) Business Days prior to the
closing of such purchase (time being of the essence), the transferee or
transferees to whom the conveyance shall be made (if other than to the Lessee),
in which case such conveyance shall (subject to the terms and conditions set
forth herein) be made to such designee; provided, however, that
such designation of a transferee or transferees shall not cause the Lessee to
be released, fully or partially, from any of its obligations under this Lease,
including, without limitation, the obligation to pay the Lessor an amount equal
to the Asset Termination Value that was not fully and finally paid by such
designee on such Expiration Date.

             20.3     Acceleration of Purchase Obligation.

                           (a)         The Lessee shall
be obligated to
purchase for an amount equal to the Asset Termination Value the Lessor's
interest in the Property (notwithstanding any prior election to exercise its
Purchase Option pursuant to Section 20.1) (i) automatically and without
notice upon the occurrence and during the continuance of any Event of Default
specified in clause (f) or (g) of Section 17.1, and (ii)
as provided for at Section 17.2(e) immediately upon written demand of
the Lessor upon the occurrence of any other Event of Default (except as
provided in Section 17.2(h).

                           (b)        The Lessee shall be
obligated to
purchase for an amount equal to the Asset Termination Value (plus all other
amounts (without duplication) owing in respect of Rent (including Supplemental
Rent) theretofore accruing) (offsetting against such amount the aggregate
amount of the Cash Collateral, if any) immediately upon written demand of the
Lessor the Lessor's interest in the Property at any time during the Term when
the Lessor ceases to have title as contemplated by Section 12.1.

ARTICLE
XXI.

             21.1     Renewal.

                           (a)        
 Subject to the conditions set forth
herein, the Lessee shall have the option (the "Renewal Option")
by written request (the "Renewal Request") to the Lessor and
the Agent (which request the Agent shall promptly forward to each Participant)
and each Participant given not later than 180 days prior to the Expiration Date
then in effect, to renew the Term for an additional period as specified in such
Renewal Request, commencing on the date following the Expiration Date then in
effect. No later than the date (the "Renewal Response Date")
which is ninety (90) days after such request has been delivered to each of the
Lessor and the Agent, the Lessor will notify the Lessee in writing (with a copy
to Agent) whether or not it consents to such Renewal Request (which consent may
be granted or denied in its sole discretion and may be conditioned on receipt
of such financial information or other documentation as may reasonably be specified
by the Lessor including without limitation a satisfactory appraisal of the
Property), provided that if the Lessor shall fail to notify the Lessee
on or prior to the Renewal Response Date, it shall be deemed to have denied
such Renewal Request.  If the Lessor
shall have consented to the Renewal Request, the Renewal Term contemplated by
such request shall become effective as of the Expiration Date then in effect
after the Lessor has consented to such Renewal Request (each an "Extension
Effective Date"); provided that such renewal shall be subject to and
conditioned upon the following:

                           (A)       on both the Extension
Effective Date and
the date of the Renewal Request, (i) no Default or Event of Default shall have
occurred and be continuing, and (ii) the Lessor and the Agent shall have
received a Responsible Officer's Certificate of the Lessee as to the matters
set forth in clause (i) above,

                           (B)        the Lessee shall not
have exercised the
Remarketing Option, and

                           (C)        the Participants shall
have agreed to
extend the Maturity Date contemporaneously therewith pursuant to Section 3.6 of
the Participation Agreement such that the Renewal Term will expire on the same
date as the extended Maturity Date.

                           (b)        As of any date of
determination
following the Initial Expiration Date (in the event a Renewal Term is granted
hereunder), the Expiration Date shall be the date set forth in the then most
recent Extension Notice delivered by the Agent pursuant to Section 3.6 of the
Participation Agreement.

ARTICLE XXII.

             22.1     
Option to Remarket.  Subject to the fulfillment of each of the
conditions set forth in this Section 22.1, the Lessee shall have the
option (the "Remarketing Option") to market for the Lessor and
complete the sale of all, but not less than all, of the Lessor's interest in
the Property on the Expiration Date for the Lessor.

                           The
Lessee's effective exercise and consummation of the Remarketing Option shall be
subject to the due and timely fulfillment of each of the following provisions
as of the dates set forth below.

                           (a)         Not later than one
hundred eighty (180)
days prior to the Expiration Date, the Lessee shall give to the Lessor written
notice of the Lessee's exercise of the Remarketing Option, which exercise shall
be irrevocable (except by delivery of a Purchase Notice and consummation of the
exercise of the Purchase Option prior to the earlier of (i) the Expiration Date
or (ii) the date on which the Lessor enters into a binding contract to sell the
Property pursuant to the exercise of the Remarketing Option).

                           (b)        The Lessee shall deliver
to the Lessor
an Environmental Audit of the Property together with its notice of exercise of
the Remarketing Option.  Such
Environmental Audit shall be prepared by an environmental consultant selected
by the Lessor in the Lessor's reasonable discretion and shall contain
conclusions reasonably satisfactory to the Lessor as to the environmental
status of the Property.  If such
Environmental Audit indicates any material exceptions reasonably requiring
remedy or further investigation, the Lessee shall have also delivered a Phase
Two environmental assessment by such environmental consultant prior to the
Expiration Date showing the completion of the remedying of such exceptions in
compliance with Environmental Laws. The reasonable, customary and documented
costs and expenses of the Lessee in complying with this Section 22.1(b)
shall at the request of the Lessee be paid or reimbursed from the gross
proceeds of a sale of the Property.

                           (c)         On the date of the
Lessee's notice to
the Lessor of the Lessee's exercise of the Remarketing Option, other than a
notice given pursuant to Section 17.2(h), no Event of Default or Default shall
exist, and thereafter, no uncured Event of Default or Default shall exist.

                           (d)        The Lessee shall have
completed in all
material respects all Modifications, restoration and rebuilding of the Property
pursuant to Sections 11.1 and 15.1(e) (as the case may be) and
shall have fulfilled in all material respects all of the conditions and
requirements in connection therewith pursuant to said Sections, in each case by
the date on which the Lessor receives the Lessee's notice of the Lessee's
exercise of the Remarketing Option (time being of the essence), regardless of
whether the same shall be within the Lessee's control.  The Lessee shall have also paid the cost of
all Modifications commenced prior to the Expiration Date.  The Lessee shall not have been excused
pursuant to Section 13.1 from complying with any Applicable Law that
involved the extension of the ultimate imposition of such Applicable Law beyond
the last day of the Term.  Any Permitted
Exceptions on the Property that were contested by the Lessee shall have been
removed.

                           (e)         During the Marketing Period, the
Lessee
shall, as nonexclusive agent for the Lessor, use commercially reasonable
efforts to sell the Lessor's interest in the Property on or prior to the
Expiration Date (without diminishing the Lessee's obligation to consummate the
sale on the Expiration Date) and will attempt to obtain the highest purchase price
therefor and for not less than the Fair Market Sales Value.  The Lessee will be responsible for hiring
and compensating brokers and making the Property available for inspection by
prospective purchasers.  The Lessee
shall promptly upon request permit inspection of the Property and any
maintenance records relating to the Property by the Lessor, any Participant and
any potential purchasers, and shall otherwise do all things necessary to sell
and deliver possession of the Property to any purchaser. The reasonable,
customary and documented costs and expenses of the Lessee in complying with
this Section 22.1(e) shall at the request of the Lessee be paid or
reimbursed from the gross proceeds of a sale of the Property.  The Lessee shall allow the Lessor and any
potential qualified purchaser reasonable access to the Property for the purpose
of inspecting the same.

                           (f)         The Lessee shall
submit all bids to the
Lessor and the Agent, and the Lessor will have the right to review the same and
the right to submit any one or more bids. 
Any bid shall be on an all-cash basis unless the Lessor, the Agent and
the Participants shall otherwise agree in their sole discretion.  The Lessee shall use its best efforts to
procure bids from one or more bona fide prospective purchasers and shall
deliver any such bids to the Lessor and the Agent not less than ninety (90)
days prior to the Expiration Date a binding written unconditional (except as
set forth below), irrevocable offer by such purchaser or purchasers offering
the highest bid to purchase the Property. No such purchaser shall be the
Lessee, or any Subsidiary or Affiliate of the Lessee.  The written offer must specify the Expiration Date as the closing
date unless the Lessor, the Agent and the Participants shall otherwise agree in
their sole discretion.

                           (g)        In connection with any
such sale of the
Property, the Lessee will provide to the purchaser all customary
"seller's" indemnities, representations and warranties regarding
title, absence of Liens (except Lessor Liens) and the condition of the
Property, as well as such other terms and conditions as may be negotiated
between the Lessee and the purchaser. 
The Lessee shall have obtained all required governmental and regulatory
consents and approvals and shall have made all filings as required by
Applicable Law in order to carry out and complete the transfer of the Property.
The reasonable, customary and documented costs and expenses of the Lessee in
complying with this Section 22.1(g) shall at the request of the Lessee
be paid or reimbursed from the gross proceeds of a sale of the Property.  As to the Lessor, any such sale shall be
made on an "as is, with all faults" basis without representation or
warranty by the Lessor other than the absence of Lessor Liens and Liens created
by the Operative Documents.  Any
agreement as to such sale shall be made subject to the Lessor's rights
hereunder.

                           (h)        All prorations, credits,
costs and
expenses of the sale of the Property, whether incurred by the Lessor, the
Participants or the Lessee, including without limitation, the cost of all title
insurance, surveys, environmental reports, appraisals, transfer taxes, the
Lessor's, the Participants' and the Agent's reasonable attorneys' fees, the
Lessee's attorneys' fees, commissions, escrow fees, recording fees, and all
applicable documentary and other transfer taxes, shall be paid from the gross
sale proceeds.  Notwithstanding the
foregoing, any such amounts to be paid to the Lessee shall be so paid only to
the extent such amounts are reasonable, customary and documented and only to
the extent requested by the Lessee.

                           (i)          The Lessee
shall pay to the Agent on
the Expiration Date (or to such other Person as the Lessor shall notify the
Lessee in writing, or in the case of Supplemental Rent, to the Person entitled
thereto) an amount equal to the Residual Value Guarantee Amount (which shall be
paid in accordance with Section 3.22 of the Participation Agreement) plus
(without duplication) all Rent and all other amounts hereunder which have
accrued or will accrue prior to or as of the Expiration Date, in the type of
funds specified in Section 3.4 hereof.

                           (j)          If, within ninety (90)
days prior to
the Expiration Date, it is determined (based upon the highest bid by a
purchaser to purchase the Property pursuant to paragraph (f) of this Section
22.1) that there would, after giving effect to the proposed sale of the
Property, be a Shortfall Amount, the Lessee (i) shall cause to be delivered to
the Lessor and the Agent the End of Term Report required by Section 13.2 of the
Participation Agreement and (ii) shall on the Expiration Date pay to the Agent
(or to such other person as the Lessor shall notify the Lessee in writing), the
amounts (not to exceed the Shortfall Amount) required to be paid pursuant to
Section 13.2 of the Participation Agreement.

                           (k)         The purchase of
the Property shall be
consummated on the Expiration Date following the payment by the Lessee pursuant
to paragraphs (i) and (j) above and contemporaneously with the
Lessee's surrender of the Property pursuant to Section 19.1(b) and the
Net Sales Proceeds of the sale of the Property shall be paid directly to the
Agent; provided, however, that if the sum of the Net Sales
Proceeds from such sale of the Property plus the Residual Value Guarantee Amount
paid by Lessee pursuant to paragraph (i) above exceeds the Asset
Termination Value as of such date, then the excess shall be paid to the Lessee
on the Expiration Date.

                           (l)          The Lessee
shall not be entitled to
exercise or consummate the Remarketing Option if a circumstance that would
permit the Lessor to require the Lessee to repurchase the Property under Section
16.3 exists and is continuing.

                           (m)        No subleases affecting
the Property
shall be in effect on the Expiration Date.

             If one or more of the foregoing
provisions shall not be fulfilled as of the relevant date set forth above, then
the Lessor shall declare by written notice to the Lessee the Remarketing Option
to be null and void (whether or not it has been theretofore exercised by the
Lessee) as to the Property, in which event all of the Lessee's rights under
this Section 22.1 shall immediately terminate and the Lessee shall be
obligated to vacate the Property on the Expiration Date and comply with the
obligations set forth in Section 22.3. 
Except as expressly set forth herein, the Lessee shall have no right,
power or authority to bind the Lessor in connection with any proposed sale of
the Property.

             If the Lessee has paid the Residual
Value Guarantee Amount as required herein and in Section 3.22 of the
Participation Agreement, proceeds from a sale of the Property pursuant to the
Remarketing Option or, if not sold as provided in this Section 22.1 from
a sale of the Property occurring thereafter shall be distributed as provided in
Section 3.14 of the Participation Agreement.

             22.2     Certain Obligations Continue.  During
the Marketing Period, the obligation of the Lessee to pay Rent (including the
installment of Basic Rent due on the fifth anniversary of the Closing Date or
at the end of any Renewal Term, as the case may be) shall continue undiminished
until payment in full to the Lessor, for deposit into an account with the Agent
(or as otherwise required pursuant to Section 3.22 of the Participation
Agreement), of the Net Sales Proceeds, the Residual Value Guarantee Amount, and
(without duplication) all other amounts due to the Lessor with respect to the
Property under the Operative Documents. 
The Lessor shall have the right, but shall be under no duty, to solicit
bids, to inquire into the efforts of the Lessee to obtain bids or otherwise to
take action in connection with any such sale, other than as expressly provided
in this Article XXII.

             22.3     Support Obligations.
In the event that (A) the Lessee does not elect to purchase the Property on the
Expiration Date, (B) this Lease is terminated without a purchase of the
Property by the Lessee as expressly permitted herein, or (C) pursuant to the
Lessor's exercise of remedies under Article XVII, this Lease is
terminated, the Lessee shall, upon the request of the Lessor, exercise all
commercially reasonable efforts to provide the Lessor or other purchaser of the
Property, effective on the Expiration Date or earlier termination of this
Lease, with (i) all permits, certificates of occupancy, governmental licenses
and authorizations necessary to use and operate the Property for its intended
purposes (to the extent such items are transferable), (ii) such easements,
licenses, rights-of-way and other rights and privileges in the nature of an
easement (as are reasonably necessary or desirable in connection with the use,
repair, access to or maintenance of the Property), and (iii) any service
agreements, contracts or subcontracts in existence at such time relating to the
use and operation of the Property, in each case to the extent assignable.  All assignments, licenses, easements,
agreements and other deliveries required by clauses (i), (ii) and
(iii) of this Section 22.3 shall be in form satisfactory to the
Lessor and shall, to the extent permissible pursuant to the underlying assigned
interest or Applicable Law, be fully assignable (including both primary
assignments and assignments given in the nature of security) without payment of
any fee, cost or other charge.

ARTICLE XXIII.

             23.1     
Holding Over.  If the Lessee shall for any reason remain in
possession of the Property after the expiration or earlier termination of this
Lease (unless the Property is conveyed to the Lessee), such possession shall be
as a tenancy at sufferance during which time the Lessee shall continue to pay
Supplemental Rent that would be payable by the Lessee hereunder were the Lease
then in full force and effect and the Lessee shall continue to pay Basic Rent
at an annual rate equal to 110% of the average rate of Basic Rent payable
hereunder during the Term.  Such Basic
Rent shall be payable from time to time upon demand by the Lessor.  During any period of tenancy at sufferance,
the Lessee shall, subject to the second preceding sentence, be obligated to
perform and observe all of the terms, covenants and conditions of this Lease,
but shall have no rights hereunder other than the right, to the extent given by
law to tenants at sufferance, to continue its occupancy and use of the
Property.  Nothing contained in this Article
XXIII shall constitute the consent, express or implied, of the Lessor to
the holding over of the Lessee after the expiration or earlier termination of
this Lease (unless the Property is conveyed to the Lessee), and nothing
contained herein shall be read or construed to relieve the Lessee of its
obligations to purchase or remarket the Property on the Expiration Date
pursuant to Article XX or Article XXII or as preventing the
Lessor from maintaining a suit for possession of the Property or exercising any
other remedy available to the Lessor at law or in equity or hereunder.

ARTICLE XXIV.

             24.1     
Risk of Loss.  The Lessee assumes all risks of loss arising
from any Casualty or Condemnation which arises or occurs prior to the
Expiration Date or while the Lessee is in 
possession of the Property and all 
liability for all personal injuries and deaths and damages to property
suffered by any Person or property on or in connection with the Property which
arises or occurs prior to the Expiration Date or while the Lessee is in
possession of the Property, except in each case to the extent any such loss or
liability is primarily caused by the gross negligence or willful misconduct of
a Lessor Party.

ARTICLE XXV.

             25.1     Subletting and Assignment.
THE LESSEE MAY NOT ASSIGN THIS LEASE OR ANY OF ITS RIGHTS OR OBLIGATIONS
WITHOUT THE PRIOR WRITTEN CONSENT OF LESSOR. 
The Lessee may, without the consent of the Lessor, sublease the Property
or portion thereof to any Person, provided, that no such sublease shall,
in the opinion of the Lessor, materially adversely affect any of the Lessor's
interests, rights or remedies under the Lease or the Lessor's title to the
Property.  No assignment, sublease or
other relinquishment of possession of the Property shall in any way discharge
or diminish any of the Lessee's obligations to the Lessor hereunder and the
Lessee shall remain directly and primarily liable under this Lease as to the
Property, or portion thereof, so assigned or sublet.  Any sublease of the Property shall be made subject to and
subordinated to this Lease and to the rights of the Lessor hereunder, and shall
expressly provide for the surrender of the Property (or portion thereof) after
an Event of Default hereunder.  All such
subleases shall expressly provide for termination at or prior to the earlier of
the applicable Expiration Date or other date of termination of this Lease
unless the Lessee shall have purchased the Property pursuant to Article XX.  No assignee or sublessee shall use the
Property in a manner which is substantially different from the manner in which
the Property is used or intended for use by the Lessee or in any manner not
otherwise permitted under Section 8.2, without the prior written consent
of the Lessor.

ARTICLE XXVI.

             26.1     Estoppel Certificates.  At any time and from time to time upon not
less than twenty (20) days' prior request by the Lessor or the Lessee (the
"Requesting Party"), the other party (whichever party shall
have received such request, the "Certifying Party") shall
furnish to the Requesting Party (but not more than four times per year unless
required to satisfy the requirements of any sublessees and only to the extent
that the required information has been provided to the Certifying Party by the
other party) a certificate signed by an individual having the office of vice president
or higher in the Certifying Party certifying that this Lease is in full force
and effect (or that this Lease is in full force and effect as modified and
setting forth the modifications); the dates to which the Basic Rent and
Supplemental Rent have been paid; to the best knowledge of the signer of such
certificate, whether or not the Requesting Party is in default under any of its
obligations hereunder (and, if so, the nature of such alleged default); and
such other matters under this Lease as the Requesting Party may reasonably
request.  Any such certificate furnished
pursuant to this Article XXVI may be relied upon by the Requesting
Party, and any existing or prospective mortgagee, purchaser or lender, and any
accountant or auditor, of, from or to the Requesting Party (or any Affiliate
thereof).

ARTICLE XXVII.

             27.1     
Right to Inspect.  During the Term, the Lessee shall upon
reasonable notice from the Lessor (except that no notice shall be required if a
Event of Default has occurred and is continuing), permit the Lessor, the Agent
and their respective authorized representatives to inspect the Property during
normal business hours, provided that such inspections shall not unreasonably
interfere with the Lessee's business operations at the Property, and provided
further that the Lessee may, if it so chooses, be present during such
inspections.

             27.2     
No Waiver.  No failure by the Lessor or the Lessee to
insist upon the strict performance of any term hereof or to exercise any right,
power or remedy upon a default hereunder, and no acceptance of full or partial
payment of Rent during the continuance of any such default, shall constitute a
waiver of any such default or of any such term.  To the fullest extent permitted by law, no waiver of any default
shall affect or alter this Lease, and this Lease shall continue in full force
and effect with respect to any other then existing or subsequent default.

ARTICLE XXVIII.

             28.1     Acceptance of Surrender.  No surrender to the Lessor of this Lease or

therein shall be valid or effective unless agreed to and accepted in writing by
the Lessor and, prior to the payment or performance of all obligations under
the Participation Agreement and termination of the Commitments, the Agent, and
no act by the Lessor or the Agent or any representative or agent of the Lessor
or the Agent, other than a written acceptance, shall constitute an acceptance
of any such surrender.

ARTICLE XXIX.

             29.1     
No Merger of Title.  There shall be no merger of this Lease or of
the leasehold estate created hereby by reason of the fact that the same Person
may acquire, own or hold, directly or indirectly, in whole or in part, (a) this
Lease or the leasehold estate created hereby or any interest in this Lease or
such leasehold estate, or (b) any estate of others in the Property created by
any sublease permitted under this Lease, except as may expressly be stated in a
written instrument duly executed and delivered by the appropriate Person.

ARTICLE XXXI.

             31.1     
Miscellaneous.  Anything contained in this Lease to the
contrary notwithstanding, all claims against and liabilities of the Lessee or
the Lessor arising from events commencing prior to the expiration or earlier
termination of this Lease shall survive such expiration or earlier
termination.  If any term or provision
of this Lease or any application thereof shall be declared invalid or
unenforceable, the remainder of this Lease and any other application of such
term or provision shall not be affected thereby.  If any right or option of the Lessee provided in this Lease,
including any right or option described in Articles XV, XVI, XX,
XXI or XXII, would, in the absence of the limitation imposed by
this sentence, be invalid or unenforceable as being in violation of the rule
against perpetuities or any other rule of law relating to the vesting of an
interest in or the suspension of the power of alienation of property, then such
right or option shall be exercisable only during the period which shall end twenty-one
(21) years after the date of death of the last survivor of the descendants of
Franklin D. Roosevelt, the former president of the United States, Henry Ford,
the deceased automobile manufacturer, and John D. Rockefeller, the founder of
the Standard Oil Company, known to be alive on the date of the execution,
acknowledgment and delivery of this Lease.

             31.2     Amendments and Modifications.  Subject to the requirements, restrictions
and conditions set forth in the Participation Agreement, neither this Lease,
any Lease Supplement nor any provision hereof may be amended, waived,
discharged or terminated except by an instrument in writing in recordable form
signed by the Lessor and the Lessee.

             31.3     Successors and Assigns.  All the terms and provisions of this Lease
shall inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

             31.4     Headings and Table of Contents.  The headings and table of contents in this
Lease are for convenience of reference only and shall not limit or otherwise
affect the meaning hereof.

             31.5     
Counterparts.  This Lease may be executed in any number of
counterparts, each of which shall be an original, but all of which shall
together constitute one and the same instrument.

             31.6     
GOVERNING LAW.  THIS AGREEMENT SHALL IN ALL RESPECTS BE
GOVERNED BY THE LAW OF THE STATE OF CALIFORNIA (EXCLUDING ANY CONFLICT OF LAW
OR CHOICE OF LAW RULES WHICH MIGHT LEAD TO THE APPLICATION OF THE INTERNAL LAWS
OF ANY OTHER JURISDICTION) AS TO ALL MATTERS OF CONSTRUCTION, VALIDITY AND
PERFORMANCE.

             31.7     Limitations on Recourse.  The
parties hereto agree that the Lessor shall have no personal liability
whatsoever to the Lessee or its respective successors and assigns for any claim
based on or in respect of this Lease or any of the other Operative Documents or
arising in any way from the transactions contemplated hereby or thereby; provided,
however, that the Lessor shall be liable in its individual capacity (a)
for its own willful misconduct or gross negligence (or negligence in the
handling of funds), (b) for liabilities that may result from the incorrectness
of any representation or warranty expressly made by it in Section 7.1 of the
Participation Agreement or from the failure of the Lessor to perform its
covenants and agreements set forth in Section 10.3 of the Participation
Agreement, and (c) for any Taxes based on or measured by any fees, commission
or compensation received by it for acting as the Lessor as contemplated by the
Operative Documents.  It is understood
and agreed that, except as provided in the preceding proviso: (i) the Lessor
shall have no personal liability under any of the Operative Documents as a
result of acting pursuant to and consistent with any of the Operative
Documents; (ii) all obligations of the Lessor to the Lessee are solely
nonrecourse obligations except to the extent that it has received payment from
others and are enforceable solely against 
the Lessor's interest in the Property; and (iii) all such personal
liability of the Lessor is expressly waived and released as a condition of, and
as consideration for, the execution and delivery of the Operative Documents by
the Lessor.

             31.8     
Original Lease.  The single executed original of this Lease
marked "THIS COUNTERPART IS THE ORIGINAL EXECUTED COUNTERPART" on the
signature page thereof and containing the receipt of the Agent therefor on or
following the signature page thereof shall be the Original Executed Counterpart
of this Lease (the "Original Executed Counterpart").  To the extent that this Lease constitutes
chattel paper, as such term is defined in the Uniform Commercial Code as in
effect in any applicable jurisdiction, no security interest in this Lease may
be created through the transfer or possession of any counterpart other than the
Original Executed Counterpart.
