to record any such amounts or any error in doing so shall not, however, limit or
otherwise affect the obligation of the Borrower hereunder to pay any amount
owing with respect to the Loans.

          (b) Upon the request of any Bank made through the Administrative
Agent, the Loans made by such Bank may be evidenced by one or more Notes,

outstanding Letters of Credit, but shall include the amounts of any drawings on
outstanding Letters of Credit) and maturity of each Loan made by it and the
amount of each payment of principal made by the Borrower with respect thereto.
Each such Bank is irrevocably authorized by the Borrower to endorse its Note(s),
and each Bank's record shall be conclusive absent manifest error; provided,

outstanding Letters of Credit equal to one and five-eighths percent (1.625%) per
annum of the aggregate face amount of all Letters of Credit outstanding
hereunder (as reduced by the aggregate amount of any drawings thereunder), as

           --------------------------------                                     
Base Rate Loans shall be made on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed.  All other computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed
(which results in more interest being paid than if computed on the basis of a
365-day year).  Interest and fees shall accrue during each period during which
interest or such fees are computed from the first day thereof to the last day
thereof.  Each determination of an interest rate by the Administrative Agent
shall be conclusive and binding on the Borrower and the Banks in the absence of
manifest error.

     2.11  Payments by the Borrower  .
           ------------------------   

          2.11.1   All payments (including prepayments) to be made by the
Borrower shall be made without set-off, recoupment or counterclaim.  Except as
otherwise expressly provided herein, all payments by the Borrower shall be made
to the Administrative Agent for the account of the Banks at the Administrative
Agent's Payment Office, and shall be made in dollars and in immediately
available funds, no later than 11:00 a.m. San Francisco time on the date
specified herein.  The Administrative Agent will promptly distribute to each
Bank its Pro Rata Share (or other applicable share as expressly provided herein)
of such payment in like funds as received.  Any payment received by the
Administrative Agent later than 11:00 a.m. San Francisco time shall be deemed to
have been received on the following Business Day, and any applicable interest or
fee shall continue to accrue.

          2.11.2   Subject to the provisions set forth in the definition of the
term "Interest Period", whenever any payment is due on a day other than a
Business Day, such payment shall be made on the following Business Day, and such
extension of time shall in such case be included in the computation of interest
or fees, as the case may be.

          2.11.3   Unless the Administrative Agent receives notice from the
Borrower prior to the date on which any payment is due to the Banks that the

                                      -33-
<PAGE>
 
Borrower will not make such payment in full as and when required, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date in immediately available funds and the
Administrative Agent may (but shall not be so required), in reliance upon such
assumption, distribute to each Bank on such due date an amount equal to the
amount then due such Bank.  If and to the extent the Borrower has not made such
payment in full to the Administrative Agent, each Bank shall repay to the
Administrative Agent on demand such amount distributed to such Bank, together
with interest thereon at the Federal Funds Rate for each day from the date such
amount is distributed to such Bank until the date repaid.

     2.12  Payments by the Banks to the Administrative Agent  .
           -------------------------------------------------   

          2.12.1   Unless the Administrative Agent receives notice from a Bank
on or prior to the Closing Date or, with respect to any Borrowing after the
Closing Date, at least one (1)  Business Day prior to the date of such
Borrowing, that such Bank will not make available to the Administrative Agent,
for the account of the Borrower, the amount of that Bank's Pro Rata Share of the
Borrowing as and when required hereunder, the Administrative Agent may assume
that each Bank has made such amount available to the Administrative Agent in
immediately available funds on the Borrowing Date and the Administrative Agent
may (but shall not be so required), in reliance upon such assumption, make
available to the Borrower on such date a corresponding amount.  If and to the
extent any Bank shall not have made its full amount available to the
Administrative Agent in immediately available funds and the Administrative Agent
in such circumstances has made available to the Borrower such amount, that Bank
shall, on the Business Day following such Borrowing Date, make such amount
available to the Administrative Agent, together with interest at the Federal
Funds Rate for each day during such period.  A notice of the Administrative
Agent submitted to any Bank with respect to amounts owing under this Section
                                                                     -------
2.12.1 shall be conclusive, absent manifest error.  If such amount is so made
------                                                                       
available, such payment to the Administrative Agent shall constitute such Bank's
Loan on the date of Borrowing for all purposes of this Agreement.  If such
amount is not made available to the Administrative Agent on the Business Day
following the Borrowing Date, the Administrative Agent will notify the Borrower
of such failure to fund and, within five (5) Business Days following written
demand by the Administrative Agent, the Borrower shall pay such amount to the
Administrative Agent for the Administrative Agent's account, together with
interest thereon for each day elapsed since the date of such Borrowing, at a
rate per annum equal to the interest rate applicable at the time to the Loans
comprising such borrowing (but without payment of any breakage costs or other
amounts described in Section 3.4).
                     -----------  

          2.12.2   The failure of any Bank to make any Loan on any Borrowing
Date shall not relieve any other Bank of any obligation hereunder to make a Loan
on such Borrowing Date, but no Bank shall be responsible for the failure of any

                                      -34-

other Bank to make the Loan to be made by such other Bank on any Borrowing Date.
Any Bank that fails to make a Loan to the Borrower on a Borrowing Date shall be
liable to the Borrower for such failure, and the Borrower may proceed to enforce
this Agreement against such defaulting Bank.

     2.13  Sharing of Payments  .  If, other than as expressly provided
           -------------------                                         
elsewhere herein, any Bank shall obtain on account of the Obligations owing to
it any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) in excess of its Pro Rata Share, such Bank shall
immediately (a) notify the Administrative Agent of such fact, and (b) purchase
from the other Banks such participations in the Loans made by them as shall be
necessary to cause such purchasing Bank to share the excess payment pro rata
with each of them; provided, however, that if all or any portion of such excess
                   --------                                                    
payment is thereafter recovered from the purchasing Bank, such purchase shall to
that extent be rescinded and each other Bank shall repay to the purchasing Bank
the purchase price paid therefor, together with an amount equal to such paying
Bank's ratable share (according to the proportion of (i) the amount of such
paying Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  The Borrower
agrees that any Bank so purchasing a participation from another Bank may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off, as limited by Section 10.9) with respect to such
                                    ------------                      
participation as fully as if such Bank were the direct creditor of the Borrower
in the amount of such participation.  The Administrative Agent will keep records
(which shall be conclusive and binding in the absence of manifest error) of
participations purchased under this Section 2.13, and will in each case notify
                                    ------------                              
the Banks following any such purchases or repayments.

     2.14  Security  .  All obligations of the Borrower under this Agreement,
           --------                                                          
the Notes and all other Loan Documents (but not including the Environmental
Indemnity) shall be secured in accordance with the Collateral Documents.

     2.15  Reconveyance  .
           ------------   

          2.15.1   Reconveyance of a Property.  The Administrative Agent shall

     and transfer of real property;

     and be continuing, except the occurrence of any Monetary Default or Event
     of Default that would be fully cured by the reconveyance or release of such
     Property from the lien of the applicable Deed of Trust; and

               (e0   The Borrower shall have delivered to the Administrative
     Agent such endorsements to the Administrative Agent's policies of title
     insurance covering the Deeds of Trust as the Administrative Agent may

                   ---------------------------------------                     
Agent shall reconvey a parcel ("Parcel") of a Property from the lien of the

Parcel, or upon the Borrower=s request, upon the satisfaction of all of the
following conditions precedent:

     Agent, at least thirty (30) days prior to the requested reconveyance date,
     a written request for reconveyance of the applicable Parcel, accompanied by
     the certificate of a Responsible Officer (to which a true and complete copy
     of the purchase and sale or exchange agreement for the Parcel, if any,
     shall be attached as an exhibit) setting forth, in such detail as the
     Administrative Agent may reasonably require, (i) if applicable, the gross
     purchase price of the Parcel and (ii) a calculation of the value of the
     Parcel (determined by multiplying the average per acre value of the Parcel,
     based on the last full appraisal of the Property from which the Parcel is
     to be released, by the size of the Parcel in acres (and fractions
     thereof));

               (b) The Administrative Agent shall have determined the
     Availability which would exist following the release of the Parcel by
     revaluing the Property from which such Parcel is to be released (the

     Appraisal (which review and update may result in a change in the As-Is
     Appraised Value of the Revaluation Property, but shall be based on a

     Borrower shall cooperate with the Administrative Agent and provide the
     Administrative Agent and its appraiser with all information regarding the
     Revaluation Property reasonably required by the Administrative Agent or
     such appraiser to prepare an Appraisal update for such Property.   Promptly

     the subject Parcel would be less than the aggregate principal amount
     outstanding on the Loans, the Administrative Agent shall notify the
     Borrower of such fact and of the amount of any principal prepayment
     necessary to reduce the aggregate principal amount outstanding on the Loans
     to the amount of the Availability.  The Borrower shall thereupon have the
     right to cause the condition precedent contained in this Section 2.15.2(b)

     Administrative Agent's notice to the Borrower of the amount of any Required
     Principal Reduction, the Borrower shall pay such Required Principal
     Reduction to the Administrative Agent, for the account of the Banks, in
     accordance with the mandatory prepayment provisions of Section 2.6;

     other easements over the real property to be reconveyed for the benefit of
     the remaining Property as may be reasonably required by the Administrative
     Agent;

In addition, upon the reconveyance or release of all of a Sale-Leaseback
Property from the lien of the Deed of Trust encumbering such Sale-Leaseback
Property, the Administrative Agent shall also release any liens or security
interests it may then hold in any of the Borrower's other rights or interests in
such Sale-Leaseback Property, including any assignment of the Borrower's option
to purchase the Sale-Leaseback Property and any pledge of the purchase money
note payable to the Borrower and secured by one or more deeds of trust
encumbering the fee interest in such Sale-Leaseback Property.

LIBOR Loan, then within thirty (30) days following such Lender's request, from
time to time the Borrower shall pay all such Taxes and shall also pay to the
Administrative Agent, at the time interest is paid, all additional amounts which
such Bank specifies as necessary to preserve the yield, after payment of such
Taxes, that such Bank would have received if such taxes had not been imposed;

days prior to the date on which such Bank gave notice to the Borrower of the
circumstance entitling such Bank to compensation.  Each Bank agrees to notify
the Borrower promptly of its actual knowledge of any event that would entitle
such Bank to compensation under this Section 3.1 (and further agrees to

designate a different Lending Office with respect to its LIBOR Loans if such
redesignation will avoid the need for or reduce the amount of any such
compensation and will not, in the judgment of such Bank, be illegal or otherwise
disadvantageous to such Bank); provided further, however, that a Lender's

failure to give any such notice shall not affect the Borrower's obligation to
pay such compensation, except as otherwise expressly provided above.  If any
Bank claims compensation or a right to reimbursement under this Section 3.1, the

          3.2.1   If any Bank determines that (a) the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, occurring after the
date of this Agreement has made it unlawful, or (b) any central bank or other
Governmental Authority has asserted after the date of this Agreement that it is
unlawful for such Bank or its applicable Lending Office to make LIBOR Loans,
then, on notice thereof by such Bank to the Borrower and the Administrative
Agent, any obligation of such Bank to make LIBOR Loans shall be suspended until
such Bank notifies the Administrative Agent and the Borrower that the

circumstances giving rise to such determination no longer exist.

          3.2.2   If any Bank determines that it is unlawful to maintain any
LIBOR Loan, the Borrower shall, upon its receipt of notice of such fact and
demand from such Bank (with a copy to the Administrative Agent), prepay in full
such Bank's LIBOR Loans then outstanding, together with interest accrued
thereon, but without any amounts that would otherwise be required to be paid in
connection with such prepayment under Section 3.4, either on the last day of the

Interest Period thereof, if such Bank may lawfully continue to maintain such
LIBOR Loans to such day, or immediately, if such Bank may not lawfully continue
to maintain such LIBOR Loans.  If the Borrower is required to so prepay any
LIBOR Loan, then concurrently with such prepayment, the Borrower shall borrow
from the affected Bank, in the amount of such repayment, a Base Rate Loan.

          3.2.3   If the obligation of any Bank to make or maintain LIBOR Loans
has been so terminated or suspended, the Borrower may elect, by giving notice to
such Bank and the Administrative Agent, that all Loans which would otherwise be
made by such Bank as LIBOR Loans shall be instead Base Rate Loans.

          3.2.4   Before giving any notice to the Borrower and the
Administrative Agent under this Section 3.2, the affected Bank shall designate a
                                -----------

will avoid the need for giving such notice or making such demand and will not,
in the judgment of such Bank, be illegal or otherwise disadvantageous to such
Bank.

          3.3.1   If any Bank determines that, due to either (i) the
introduction of, or any change in or in the interpretation of, any law or
regulation occurring after the date of this Agreement or (ii) the compliance by
such Bank (or its Lending Office) with any guideline or request from any central
bank or other Governmental Authority (whether or not having the force of law)
imposed after the date hereof, there shall be any increase in the cost to such
Bank of agreeing to make or making, funding or maintaining any LIBOR Loans, then
the Borrower shall be liable for, and shall from time to time, within thirty
(30) days of demand by such Bank (with a copy of such demand to be sent to the
Administrative Agent), pay to the Administrative Agent, for the account of such
Bank, additional amounts as are sufficient to compensate such Bank for such
increased costs; provided, however, that the Borrower shall not be obligated to

hereunder shall, in the absence of manifest error, be conclusive and binding for
all purposes so long as the amount claimed is calculated and charged in the same
manner as such amounts are generally calculated and charged for such Bank's
other similarly situated borrowers.  Each Bank agrees promptly to notify the
Borrower (with a copy to the Administrative Agent) of its actual knowledge of
any event that would entitle such Bank to compensation under this Section 3.3.1

Capital Adequacy Regulation, (iii) any change in the interpretation or
administration of any Capital Adequacy Regulation by any central bank or other
Governmental Authority charged with the interpretation or administration
thereof, or (iv) compliance by such Bank (or its Lending Office), or any
corporation controlling such Bank, with any Capital Adequacy Regulation imposed
after the date hereof affects or would affect the amount of capital required or
expected to be maintained by such Bank or any corporation controlling such Bank,
and such Bank (taking into consideration such Bank's or such corporation's
policies with respect to capital adequacy and such Bank's desired return on
capital) determines that the amount of such capital is increased as a
consequence of its Commitment, loans, credits or obligations under this
Agreement, then, within thirty (30) days of such Bank's demand to the Borrower
(with a copy to the Administrative Agent), the Borrower shall pay to the
Administrative Agent, for the account of such Bank, from time to time as
specified by such Bank, additional amounts sufficient to compensate such Bank
for such increase; provided, however, that the Borrower shall not be obligated

to pay to the Administrative Agent, for the account of such Bank, any
compensation attributable to any period prior to the date that is ninety (90)
days prior to the date on which such Bank gives notice to the Borrower of the
circumstance entitling such Bank to compensation.  Each Bank agrees promptly to
notify the Borrower (with a copy to the Administrative Agent) of any
circumstances that would cause the Borrower to pay additional amounts pursuant
to this Section 3.3.2; provided further, however, that a Bank's failure to give

as a consequence of:

after the Borrower has given (or is deemed to have given) a Notice of Borrowing
or a Notice of Conversion/Continuation;

          (b0  the Borrower's failure to make any prepayment in accordance with
any notice delivered under Section 2.5;

equal to the sum of (i) $250.00 and (ii) the amount, if any, by which X exceeds
Y, and (iii) all other costs and expenses that such Bank would reasonably expect
to incur in connection with the prepayment of the applicable LIBOR Loans, where
"X" equals the additional interest that would have accrued on the principal
amount of the LIBOR Loan prepaid, without regard to the Applicable Margin, if
that principal amount had remained outstanding until the last day of the
applicable Interest Period, and "Y" equals the interest that such Bank could
recover by placing the prepaid funds on deposit in the London U.S. Dollar
interbank market for a period beginning on the day of prepayment and ending on
the last day of the applicable Interest Period, or for a comparable period for
which an appropriate rate quote can be obtained.  For purposes of calculating
amounts payable by the Borrower to a Bank under this Section 3.4 and under

Period with respect to a proposed LIBOR Loan, or that the LIBOR applicable

proposed LIBOR Loan does not adequately and fairly reflect the cost to such
Banks of funding such Loan (and, as a matter of general policy, the Majority
Banks are not making LIBOR Loans to other borrowers similarly situated), the
Administrative Agent will promptly so notify the Borrower and each Bank.
Thereafter, the obligation of the Banks to make or maintain LIBOR Loans
hereunder shall be suspended until the Administrative Agent, upon the
instruction of the Majority Banks, revokes such notice in writing.  Upon receipt
of such notice, the Borrower may revoke any Notice of Borrowing or Notice of
Conversion/Continuation then submitted by it.  If the Borrower does not revoke
such Notice, the Banks shall make, convert or continue the Loans, as proposed by
the Borrower, in the amount specified in the applicable notice submitted by the
Borrower, but such Loans shall be made, converted or continued as Base Rate
Loans instead

of LIBOR Loans.  No breakage or other costs described in Section 3.4 shall be

manifest error.

Counsel) and perfected first priority lien.  When financing statements have been
duly filed, such Deed of Trust shall also create a legal, valid, enforceable
(subject to any qualifications on enforceability set forth in the Opinions of
Counsel) and perfected first lien on, and security interest in, all right, title
and interest of the Borrower or CRG, as applicable, in all personal property and
fixtures covered by such Deed of Trust, subject to no other Liens except

is, the inability of computers, as well as embedded microchips in non-computing
devices, to properly perform date-sensitive functions with respect to certain
dates prior to and after December 31, 1999).  The Borrower is developing that
program, and reasonably anticipates that it will substantially avoid the Year
2000 problem as to all computers, as well as embedded microchips in non-
computing devices, that are material to the Borrower's business, properties or

                                      -60-

contingency plans adequate to ensure uninterrupted and unimpaired business
operation in the event of failure of its own or a third party's systems or
equipment due to the Year 2000 problem, including those of vendors, customers or
suppliers, as well as a general failure of or interruption in its communications

Collateral Documents, while any Obligation remains outstanding, the Borrower
shall maintain or cause to be maintained, with insurers reasonably approved by
the Administrative Agent and the Majority Banks, the following policies of
insurance with respect to each Property (except that the Borrower shall not be
required to maintain or cause to be maintained the insurance required under (i)
clauses (a) and (b), below, with respect to any Ground Leased Property, or (ii)
clauses (a), (b), (d) and (e), below, with respect to any Property consisting
solely of Entitled Land, whether or not subject to a ground lease), in form and
substance reasonably satisfactory to the Administrative Agent and the Majority
Banks:

          (a) blanket property insurance covering 100% of the replacement cost
of the improvements located on such Property in the event of fire, lightning,
windstorm, vandalism, malicious mischief and all other risks normally covered by
"all risk" coverage policies in the area where the Property is located
(including loss by flood if the Property is in an area designated as subject to
the danger of flood);

          (b) blanket (i.e., policies covering the Properties and other
properties of the Borrower and its subsidiaries) earthquake insurance, to the

outside California, and blanket earthquake insurance, with limits of at least
$35,000,000 and with deductibles not in excess of 10% of the insured value of
the improvements, covering Properties located within California (to the extent
that such coverage and/or deductible is available at commercially reasonable
rates);

          (c) blanket public liability and property damage insurance in amounts
reasonably required by the Administrative Agent from time to time, and in no
event less than $5,000,000 for "single occurrence";

          (d) such rental loss insurance as the Administrative Agent reasonably
requires (including insurance against income loss during a period of restoration
of at least twelve (12) months), which insurance coverage may be included in the
policies described in subparagraphs (a) and/or (b), above;

          (e) workers' compensation insurance to the extent required by law in
connection with any Property; and

          (f) all other insurance reasonably required by the Administrative

All such insurance shall provide that such policies shall not be canceled for
non-payment of premium, without at least ten (10) days' prior written notice to
the Administrative Agent, or otherwise canceled, surrendered without replacement
or materially amended (which term shall include any reduction in the scope or
limits of coverage) without at least thirty (30) days' prior written notice to
the Administrative Agent.  The policies required under subparagraphs (a), (b)
and (d) shall include a "lender's loss payable endorsement" (Form 438BFU or its
equivalent) in form and substance satisfactory to the Administrative Agent,
assuring the Administrative Agent that all proceeds shall be paid to
Administrative Agent, for the benefit of the Banks, as encumbrancer.  BofA, as
Administrative Agent, in all cases for the benefit of the Banks, shall be named
as an additional insured in the policies required under subparagraph (c).  No
such insurance (other than earthquake insurance) shall include deductible
amounts in excess of $100,000 to which the Administrative Agent has not
previously consented in writing.  Certificates of insurance for the above
policies (and/or, with respect to property insurance policies, certified copies
of the original policies, if required by the Administrative Agent) shall be
delivered to the Administrative Agent from time to time within ten (10) days
following written demand.  All policies insuring against damage to the
improvements located on any Property shall contain an agreed value clause or
equivalent coverage sufficient to eliminate any risk of co-insurance.  Prior to
the expiration of any such policy, the Borrower shall deliver to the
Administrative Agent evidence of renewal or replacement of such policy
reasonably satisfactory to the Administrative Agent.

any Property:

          (a) all tax liabilities, assessments and governmental charges or
levies upon any Property; and

          (b) all other lawful claims which, if unpaid, would by law become a
Lien upon any such Property;

and all other obligations and liabilities in excess of $10,000.00 with respect
to any Property.  Notwithstanding the foregoing clauses (a) and (b), the
Borrower shall not be required to pay any such claim, tax, assessment or
governmental charge so long as (i) its validity is being contested in good faith
and by appropriate proceedings and (ii) the Borrower has demonstrated to the
Administrative Agent's reasonable satisfaction that leaving such claim, tax,
assessment or governmental charge unpaid or unperformed pending the outcome of
such proceedings could not, in the Administrative Agent's reasonable judgment,
result in the sale of any Property to satisfy such claim, tax, assessment or
governmental charge or otherwise impair the Banks' interests under the Loan
Documents; provided that, if at any time the Administrative Agent reasonably
           --------

Administrative Agent may require the Borrower to deliver to the Administrative
Agent a bond or other Surety Instrument reasonably satisfactory to the

its business (including the Federal Fair Labor Standards Act), except such (i)
as may be contested in good faith, (ii) as to which a bona fide dispute may

to cause a Material Adverse Effect.

financial transactions and matters involving the assets and business of the
Borrower.  Subject to the requirements of Section 10.8, the Borrower shall

or any Bank to visit and inspect any of the Properties, to examine its
corporate, financial and operating records, and make copies thereof or abstracts
therefrom, and to discuss its affairs, finances and accounts with its directors,
officers, agents and independent public accountants, all at such reasonable
times during normal business hours and as often as may be reasonably desired,
upon reasonable advance notice to the Borrower; provided, however, that when an
                                                --------

foregoing at the expense of the Borrower at any time during normal business

conducting any inspections of any Property, shall comply with reasonable
restrictions on access imposed by tenants under tenant leases.

the Borrower shall submit to the Administrative Agent, at the Borrower's sole
cost and expense, at reasonable intervals, a report prepared by the Borrower
providing an update of the status of any environmental, health or safety
compliance, hazard or liability issue identified in any notice or report
required pursuant to subsection 6.3(d), that could, individually or in the
                     -----------------                                    
aggregate, reasonably be expected to cause a Material Adverse Effect.

written information, exhibits and reports furnished by or through the Borrower
to the Administrative Agent or the Banks do not and will not contain any untrue
statement of a material fact and do not and will not omit to state any material
fact or any fact necessary to make the statements contained therein not

upon the Administrative Agent's failure to respond within such fifteen (15)
Business Day period, the Borrower shall give a second notice to the
Administrative Agent and all of the Banks requesting approval or disapproval of
such lease provision(s), and the Administrative Agent's failure to respond
within ten (10) Business Days after receipt of such second notice shall be
deemed approval of such lease provision(s) by the Majority Banks.  The Banks
agree not to unreasonably withhold their consent to any such lease provision(s)
(which the Banks may evaluate, for such purposes, in the context of both the
specific Property affected by such lease and all of the Properties considered as
a portfolio).  Concurrently with its execution of a Material Lease of any
Property, the Borrower shall deliver to the Administrative Agent a copy of such
signed Material Lease, together with an estoppel certificate in the form of

all of its assets (whether now owned or hereafter acquired) to or in favor of
any Person, except that the Borrower may merge or consolidate with another
Person provided that (i) the Borrower is the continuing or surviving corporation
and (ii) such merger or consolidation does not cause a Material Adverse Effect.

Loan Documents and/or the Environmental Indemnity; (iii) to make all decisions
under the Loan Documents or the Environmental Indemnity in connection with the
day-to-day administration of the Loans, any inspections required by the Loan

Administrative Agent shall furnish to Banks copies of material documents,
including confidential ones, received from the Borrower regarding the Loans, the
Loan Documents, the Environmental Indemnity, the Collateral, any proposed new
Collateral  and the transactions contemplated hereby and thereby.  The
Administrative Agent shall have no responsibility with respect to the
authenticity, validity, accuracy or completeness of the information provided.

     9.3  Limitation on the Administrative Agent's Duties  .  Notwithstanding
          -----------------------------------------------                    
any contrary provision of any Loan Document or the Environmental Indemnity, the
Administrative Agent shall not have any duties or responsibilities except those
expressly set forth in the Loan Documents, the Environmental Indemnity or the
Co-Lender Agreement, nor shall the Administrative Agent have any fiduciary
relationship with any Bank, and no implied covenants, responsibilities, duties,
obligations or liabilities shall be read into this Agreement, any other Loan
Document, the Environmental Indemnity or the Co-Lender Agreement against the
Administrative Agent.

     9.4  Acknowledgment of the Co-Lender Agreement  .  The Borrower

The Administrative Agent, the Documentation Agent or any Co-Agent may, and at
the request of the Majority Banks shall, resign as Administrative Agent,
Documentation Agent or Co-Agent, as the case may be, upon thirty (30) days'
notice to the Banks.  If the Administrative Agent resigns under this Agreement,
the Majority Banks shall appoint from among the Banks a successor administrative
agent.  If no successor administrative agent is appointed prior to the effective
date of the resignation of the Administrative Agent, the Administrative Agent
may appoint, after consulting with the Banks, a successor administrative agent
from among the Banks.  Any successor administrative agent shall be entitled to
any fee payable by the Borrower to BofA, in its capacity as Administrative
Agent, from and after the date on which such successor administrative agent is
appointed.  If the Documentation Agent or a Co-Agent resigns under this
Agreement, the Administrative Agent shall elect either (a) to assume the rights
and obligations, if any, of such Documentation Agent or Co-Agent, as applicable,
and thereupon all references to such Documentation Agent or Co-Agent, as
applicable, shall be deemed references to the Administrative Agent, or (b) to
appoint a successor Documentation Agent or Co-Agent, as applicable, from among
the Banks.  Upon its acceptance of the appointment as successor administrative
agent, documentation agent or co-agent hereunder, as the case may be, such
successor shall succeed to all of the rights, powers and duties of the retiring
Administrative Agent, Documentation Agent or Co-Agent, as the case may be, the
term "Administrative Agent," "Documentation Agent" or "Co-Agent", as the case
may be, shall mean such successor, and the appointment, powers and duties of
such retiring Administrative Agent, Documentation Agent or Co-Agent, as the case
may be, shall terminate.  After any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the provisions of the Loan Documents or the
Environmental Indemnity regarding payment of costs and expenses and
indemnification of the Administrative Agent shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was the Administrative Agent
under this Agreement.  If no successor administrative agent has accepted
appointment as Administrative Agent by the date which is thirty (30) days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become
effective, and the Banks shall perform all of the duties of the Administrative
Agent hereunder until such time, if any, as the Majority Banks appoint a
successor administrative agent in the manner set forth above.  Upon replacement
of the Administrative Agent as provided in this Agreement, the former
Administrative Agent shall promptly deliver to the new Administrative Agent an
assignment of all beneficial interest in any Deed of Trust and any other
Collateral Documents (if before acquisition of title to the Collateral
encumbered thereby), or a quitclaim deed to and assignment of any such property
(if after acquisition of title to the Collateral encumbered thereby) and copies
of any books, records and documents related to the Loans and the Collateral to
which the Banks are entitled and which is then in the former Administrative
Agent's possession.

if such legal counsel determines in good faith that representing all such
Indemnified Persons would or could result in a conflict of interest under laws
or ethical principles applicable to such legal counsel, or that a defense or
counterclaim is available to an Indemnified Person that is not available to all
such Indemnified Persons, then to the extent reasonably necessary to avoid such
a conflict of interest or to permit unqualified assertion of such a defense or
counterclaim, each Indemnified Person shall be entitled to separate
representation by legal counsel selected by that Indemnified Person.

the parties in any way based on, arising out of or relating to this Agreement,
the other Loan Documents or any Loan (including any action or cause of action
based on or arising from an alleged tort), all decisions of fact and law shall
at the request of any party be referred to a referee in accordance with

not constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief.

          10.15.3   Real Property Collateral.  Notwithstanding the provisions of
                    ------------------------

---------------                                                           
without the consent of all parties if, at the time of the proposed submission,
such controversy or claim arises from or relates to an obligation to the
Administrative Agent or the Banks that is secured by real property collateral.
If all parties do not consent to submission of such a controversy or claim to
arbitration, the controversy or claim shall be determined by reference as
provided in Section 10.15.1.

                  -------------                                           
Agreement to exercise self-help remedies such as set off, foreclosure against or
sale of any real or personal property collateral or security, or to obtain
provisional or ancillary remedies (including provisional remedies such as claim
and delivery and ancillary remedies such as the issuance of temporary
restraining orders and preliminary injunctions pending submission of any action
or cause of action to judicial reference or arbitration as otherwise required
hereunder) from a court of competent jurisdiction before, after, or during the
pendency of any arbitration or other proceeding.  The exercise of a remedy does
not waive the right of any party to resort to arbitration or reference.  At the
Administrative Agent's option, foreclosure under a Deed of Trust or mortgage may
be accomplished either by exercise of the power of sale under the Deed of Trust
or mortgage or by judicial foreclosure.

     10.16  Entire Agreement; Amendment and Restatement  .  This Agreement,
            -------------------------------------------

understanding among the Borrower, the Banks and the Administrative Agent, and
amends, restates and supersedes in its entirety the Existing Loan Agreement and
all other prior or contemporaneous agreements and understandings of such
Persons, verbal or written, relating to the subject matter hereof and thereof.
