               THIRTEENTH AMENDMENT TO FIRST AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP

         This Thirteenth Amendment ("Amendment") to the First Amended and
Restated Agreement of Limited Partnership, is entered into by and among Sunstone
Hotel Investors, Inc., a Maryland corporation, in its individual capacity (the
"Company") and in its capacity as the General Partner of the Partnership (the
"General Partner") and O.T. Hill, LLC, a Delaware limited liability company, as
a newly admitted limited partner of the Partnership (the "Additional Limited
Partner") as of May 28, 1997. All defined terms not otherwise defined herein
shall have the meaning set forth in the Agreement (as defined below).

                                    RECITALS

         A. WHEREAS, the General Partner and certain Limited Partners executed
that certain First Amended and Restated Agreement of Limited Partnership dated
as of October 16, 1995, amending and restating that certain Limited Partnership
Agreement dated as of September 22, 1994 (as amended, the "Agreement"), and the
General Partner caused Sunstone Hotel Investors, L.P. (the "Partnership") to
file a Certificate of Limited Partnership with the Delaware Secretary of State
on September 23, 1994, thereby causing the Partnership to be formed for the
purposes set forth in the Agreement.

         B. WHEREAS, the Partnership has entered into a Capital Contribution
Agreement dated as of May 28, 1997 (the "Contribution Agreement") with the
Additional Limited Partner pursuant to which the Additional Limited Partner has
agreed to accept the Partnership Units in exchange for the contribution of the
Hotel described on Schedule 1 attached hereto (the "Additional Hotel"), subject
to certain indebtedness on the Additional Hotel.

         C. WHEREAS, in order to evidence the issuance of the Partnership Units
and the admission of the Additional Limited Partner into the Partnership, the
parties hereto desire to enter into this Agreement.

         NOW, THEREFORE, the parties hereto agree as follows:

            1. Issuance of Additional Partnership Units. Pursuant to Section
4.2(a) of the Agreement, the General Partner hereby issues a Partnership
Interest in the form of the number of Partnership Units listed on the Unitholder
Ledger to the Additional Limited Partner in consideration for the contribution
of the Additional Hotel pursuant to the terms of the Contribution Agreement.
Such issuance shall be deemed effective, and the Additional Limited Partner
shall be deemed admitted as a Limited Partner, automatically upon the closing of
the Contribution Agreement and all references to "Limited Partner" in the
Agreement shall include the Additional Limited Partner. Except as provided
herein to the contrary, the Partnership Interest issued in the foregoing
sentence shall have all of the same rights, powers and duties and


<PAGE>   2

shall be equal in all respects to the existing Partnership Interests issued to
the existing Limited Partners specifically including, without limitation, the
Redemption Rights granted pursuant to Section 8.5 of the Agreement, and the
Registration Rights granted pursuant to Section 8.6 of the Agreement.

            2. Allocations of Profit and Loss and Distributions.

               a. Pre-Closing Hotel Profits and Losses. All profits, losses and
other items earned or incurred with respect to the Additional Hotel on or prior
to the Closing Date (as defined in the Contribution Agreement) shall be
allocated to the Additional Limited Partner. All Profits, Losses and other
taxable items earned or incurred after the Closing Date shall be for the account
of the Partnership. The General Partner shall determine the amount of such items
incurred or earned on or prior to the, as opposed to after the, Closing Date in
any reasonable manner permitted under the Internal Revenue Code of 1986, as
amended (the "Code") and the Regulations.

               b. No Right to Distribution for Pre-Closing Hotel Profits. Except
as provided to the contrary in the Contribution Agreement, the Additional
Limited Partner shall not be entitled to any special distributions (or to retain
any amounts) with respect to any income generated by the Additional Hotel that
may be allocated to it for the period on or prior to the Closing Date.

               c. Proration of Distribution for Second Quarter 1997.
Notwithstanding any provision in the Agreement to the contrary, the Additional
Limited Partner shall only be entitled to a pro rata distribution of the
distribution for the quarter ending June 30, 1997 equal to normal dividend paid
to all other Partners multiplied by a fraction, the numerator of which is the
number of days after the Closing Date through June 30th and the denominator of
which is 90.

               d. Capital Accounts; Second Quarter 1997 Allocations. Upon the
admission of the Additional Limited Partner, the Partners' respective Capital
Accounts shall be adjusted to reflect the fair market value of the Partnership's
assets as prescribed in Section 4.4 of the Agreement. For purposes of
determining the Partners' respective Capital Accounts and making allocations in
the quarter ending June 30, 1997:

                  (1) The distribution for the second quarter of 1997 shall be
deemed to have been made prior to the aforementioned Capital Account adjustment
and prior to the capital contribution date.

                  (2) Notwithstanding anything in this Agreement to the
contrary, the Profits, Losses and any items thereof for the quarter ending June
30, 1997, shall be allocated among the Partners so that the per-Unit Capital
Account of the Additional Limited Partner is equal to the per-Unit Capital
Accounts of the existing Limited Partners as of the end of such quarter, after
taking into account the distribution for said quarter.

            3. Restrictions on Transfer. Notwithstanding any other provision in
the Agreement to the contrary, the Additional Limited Partner shall not convey,
assign, distribute, or otherwise voluntarily or involuntarily transfer (other
than a Pledge permitted under the Agreement) to any person, including any other
partner, any of the Partnership Units (or any other substitute securities or
other securities received on account of such Partnership Units) held by the
Additional Limited Partner at any time prior to November 28, 1997.

            4. Lock-Up Agreements. In addition to the restrictions in Section 3
above, the Additional Limited Partner shall execute a lock-up agreement at the
request of the managing underwriter in connection with any public underwritten
securities offering by the General Partner on the same terms and conditions as
any such agreement executed by Mr. Robert A. Alter, but in no event shall such
lock-up period exceed 120 days after the first date that any shares are released
for sale to the public. As a condition to any transfer of Partnership Units or
Redemption Shares otherwise permitted under the Agreement and Section 3 above,
the Additional Limited Partner shall cause any shareholder or other affiliate
who receives any Partnership Units from the Additional Limited Partner to agree
to be subject to the obligation to execute such a lock-up agreement.

            5. Agreement to be Bound. The Additional Limited Partner hereby
agrees to be bound by each of the terms and conditions of the Agreement, which
are hereby incorporated by reference.

            6. Power of Attorney. The Additional Limited Partner hereby
irrevocably constitutes and appoints the General Partner, any Liquidator, and
authorized officers and attorneys-in-fact of each, and each of those acting
singly, in each case with full power of substitution, as its true and lawful
agent and attorney-in-fact, with full power and authority in its name and place
instead to perform any of the acts set forth in Section 8.2 of the Agreement.

            7. General Provisions. Article 12 of the Agreement is hereby
incorporated by reference as if set forth in full.

            8. Effect of Amendment. Except as amended hereby, the Agreement is
hereby confirmed in all respects.

                                   ARTICLE II

                         AMOUNTS AND TERMS OF THE LOANS

                  2.1. The Loans. On the terms and subject to the conditions
contained in this Agreement, each Lender severally agrees to make loans (each a
"Loan") to the Borrower from time to time on any Business Day during the period
from the date hereof until the Termination Date in an aggregate amount not to
exceed at any time outstanding such Lender's Commitment; provided, however, that
at no time shall any Lender be obligated to make a Loan in excess of such
Lender's Ratable Portion of the Available Credit. Within the limits of each
Lender's Commitment, amounts prepaid pursuant to Section 2.7(b) or Section 7.16
may be reborrowed under this Section 2.1. The Loans of each Lender shall be
evidenced by the Note to the order of such Lender.

                  2.2. Intentionally Omitted.

                  2.3. Making the Loans. (a) Each Borrowing shall be made on
notice, given by the Borrower to the Administrative Agent not later than (i)
11:00 A.M. (Phoenix time) on the fourth (4th) Business Day prior to the date of
the proposed Borrowing in the case of Eurodollar Rate Loans, and (ii) 11:00 A.M.
(Phoenix time) on the second (2nd) Business Day prior to the date of the
proposed Borrowing in the case of Base Rate Loans. Each such notice (a "Notice
of Borrowing") shall be in substantially the form of Exhibit H, specifying
therein (i) the date of such proposed Borrowing, (ii) the aggregate amount of
such proposed Borrowing, (iii) the amount thereof, if any, requested to be
Eurodollar Rate Loans, and (iv) the initial Interest Period or Periods for any
such Eurodollar Rate Loans. The Loans shall be made as Base Rate Loans unless
(subject to Section 2.12) the Notice of Borrowing specifies that all or a pro
rata portion thereof shall be Eurodollar Rate Loans; provided, however, that the
aggregate of the Eurodollar Rate Loans for each Interest

                                       33

<PAGE>   41



Period must be in an amount of not less than $2,500,000 or an integral multiple
of $100,000 in excess thereof.

                  (b) The Administrative Agent shall give to each Lender prompt
notice of the Administrative Agent's receipt of a Notice of Borrowing and, if
Eurodollar Rate Loans are properly requested in such Notice of Borrowing, the
applicable interest rate under Section 2.9, and each Lender's Ratable Portion of
the proposed Borrowing. Each Lender shall, before 12:00 Noon (Phoenix time) on
the date of the proposed Borrowing, make available for the account of its
Applicable Lending Office to the Administrative Agent at its address referred to
in Section 11.2, in immediately available funds, such Lender's Ratable Portion
of such proposed Borrowing. By 1:00 PM (Phoenix time) in the case of Eurodollar
Rate Loans and Base Rate Loans, on the date specified by the Borrower in the
Notice of Borrowing, subject to fulfillment of the applicable conditions set
forth in Article III, the Administrative Agent will make such funds available to
the Borrower at the Administrative Agent's aforesaid address; provided that in
the event that the Administrative Agent shall not have received from a Lender
such Lender's Ratable Portion of such Borrowing, the Administrative Agent shall
be under no obligation to fund such Lender's Ratable Portion of such Borrowing.

                  (c) Each Base Rate Loan shall be in an aggregate amount of not
less than $1,000,000 or an integral multiple of $100,000 in excess thereof.

                  (d) Intentionally omitted.

                  (e) Each Notice of Borrowing shall be irrevocable and binding
on the Borrower. In the case of any proposed Borrowing which the related Notice
of Borrowing specifies is to be comprised of Eurodollar Rate Loans, the Borrower
shall indemnify each Lender against any loss, cost or expense incurred by such
Lender as a result of any failure to fulfill on or before the date specified in
such Notice of Borrowing for such proposed Borrowing the applicable conditions
set forth in Article III, including, without limitation, any loss (including,
without limitation, loss of anticipated profits), cost or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by
such Lender to fund any Eurodollar Rate Loan to be made by such Lender as part
of such proposed Borrowing when such Eurodollar Rate Loan, as a result of such
failure, is not made on such date.

                  (f) Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any proposed Borrowing that such Lender will
not make available to the Administrative Agent such Lender's Ratable Portion of
such

                                       34

<PAGE>   42



Borrowing, the Administrative Agent may assume that such Lender has made such
Ratable Portion available to the Administrative Agent on the date of such
Borrowing in accordance with this Section 2.3 and the Administrative Agent may,
in reliance upon such assumption, (but shall not be obligated to) make available
to the Borrower on such date a corresponding amount. If and to the extent that
such Lender shall not have so made such Ratable Portion available to the
Administrative Agent, the Borrower and such Lender severally agree to repay to
the Administrative Agent forthwith, (i) in the case of the Borrower, within
thirty (30) days of demand by the Administrative Agent and (ii) in the case of
such Lender, on demand by the Administrative Agent, such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the
Administrative Agent, at (x) in the case of the Borrower, the interest rate
applicable at the time to the Loans comprising such Borrowing and (y) in the
case of such Lender, the Federal Funds Rate. If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement. If the Borrower shall repay to the Administrative Agent such
corresponding amount, such payment shall not relieve such Lender of any
obligation it may have to the Borrower hereunder.

                  (g) The failure of any Lender to make the Loan to be made by
it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Loan on the date of such Borrowing,
but no Lender shall be responsible for the failure of any other Lender to make
the Loan to be made by such other Lender on the date of any Borrowing. If a
Lender fails to make a Loan to the Borrower as and when required hereunder, the
Borrower shall be entitled to any remedies available at law or in equity against
such Lender.

                  2.4. Fees. (a) The Borrower agrees to pay to the
Administrative Agent, for the account of each Lender, a fee (the "Unused
Commitment Fee") equal to 0.25% times such Lender's average daily Unused
Commitment, from the date hereof until the Termination Date, payable in arrears
with respect to each calendar quarter on (i) the first day of the second
calendar month of each calendar quarter during the term of such Lender's
Commitment, commencing August 1, 1997 and (ii) the Termination Date.

                  (b) The Borrower has agreed to pay Bank One, Credit Lyonnais
and Wells Fargo additional fees, the amounts and dates of payment of which are
embodied in a separate agreement among them and the Borrower.


                                       35

<PAGE>   43



                  2.5. Reduction and Termination of the Commitments. The
Borrower may, upon at least three Business Days' prior notice to the
Administrative Agent, terminate in whole or reduce ratably in part the Unused
Commitments of the Lenders; provided, however, that (i) each partial reduction
shall be in the aggregate amount of not less than $5,000,000 or an integral
multiple of $1,000,000 in excess thereof and (ii) no such reduction shall result
in a Borrowing Base Imbalance.

                  2.6. Repayment. The Borrower shall repay the entire unpaid
principal amount of the Loans on the Termination Date.

                  2.7. Prepayment. (a) The Borrower shall have no right to
prepay the principal amount of any Loan other than as provided in this Section
2.7.

                  (b) The Borrower may, upon at least four (4) Business Days'
prior notice to the Administrative Agent, stating the proposed date and
aggregate principal amount of the prepayment, prepay the outstanding principal
amount of the Loans in whole or ratably in part, together with accrued interest
to the date of such prepayment on the principal amount prepaid; provided,
however, that any prepayment of any Eurodollar Rate Loan made other than on the
last day of an interest Period for such Loan shall be subject to payment by the
Borrower to the Administrative Agent of any costs, fees or expenses incurred by
any Lender in connection with such prepayment including without limitation any
costs to unwind any Eurodollar Rate contracts; and, provided, further, that each
partial prepayment shall be in an aggregate principal amount not less than
$2,500,000 or integral multiples of $100,000 in excess thereof. Upon the giving
of such notice of prepayment, the principal amount of the Loans specified to be
prepaid shall become due and payable on the date specified for such prepayment.

                  (c) If at any time a Borrowing Base Imbalance exists, the
Borrower, within five (5) Business Days (or thirty (30) days if the Borrowing
Base Imbalance resulted from an event other than (i) the Disposition of, or with
respect to, an Eligible Hotel or Eligible Hotel Owner or (ii) a Hotel's ceasing
to be an Eligible Hotel for any other reason) shall prepay the Loans then
outstanding in an amount equal to such Borrowing Base Imbalance, together with
accrued interest thereon, provided, however, that, if within such five-Business
Day (or, if applicable, 30-day) period, one or more additional Eligible Hotels
shall be accepted by the Administrative Agent in accordance with the provisions
of Section 7.23, the Loans shall be required to be prepaid only to the extent,
if any, of any Borrowing Base Imbalance, as determined following the
Administrative Agent's acceptance of such additional Eligible Hotel or Eligible
Hotels.


                                       36

<PAGE>   44



                  2.8. Conversion/Continuation Option. The Borrower may elect
(i) at any time to convert Base Rate Loans or any portion thereof to Eurodollar
Rate Loans, or (ii) at the end of any Interest Period with respect thereto, to
convert Eurodollar Rate Loans or any portion thereof into Base Rate Loans, or to
continue such Eurodollar Rate Loans or any portion thereof for an additional
Interest Period; provided, however, that the aggregate of the Eurodollar Loans
for each Interest Period therefor must be in the amount of $2,500,000 or an
integral multiple of $100,000 in excess thereof. Each conversion or continuation
shall be allocated among the Loans of all Lenders in accordance with their
Ratable Portion. Each such election shall be in substantially the form of
Exhibit I hereto (a "Notice of Conversion or Continuation") and shall be made by
giving the Administrative Agent at least three (3) Business Days' prior written
notice thereof specifying (A) the amount and type of conversion or continuation,
(B) in the case of a conversion to or a continuation of Eurodollar Rate Loans,
the Interest Period therefor, and (C) in the case of a conversion, the date of
conversion (which date shall be a Business Day and, if a conversion from
Eurodollar Rate Loans, shall also be the last day of the Interest Period
therefor). The Administrative Agent shall promptly notify each Lender of its
receipt of a Notice of Conversion or Continuation and of the contents thereof
and such Lender's Ratable Portion of the Loans to be converted. Notwithstanding
the foregoing, no conversion in whole or in part of Base Rate Loans to
Eurodollar Rate Loans, and no continuation in whole or in part of Eurodollar
Rate Loans upon the expiration of any Interest Period therefor, shall be
permitted at any time at which a Default or an Event of Default shall have
occurred and be continuing. If, within the time period required under the terms
of this Section 2.8, the Administrative Agent does not receive a Notice of
Conversion or Continuation from the Borrower containing a permitted election to
continue any Eurodollar Rate Loans for an additional Interest Period or to
convert any such Loans, then, upon the expiration of the Interest Period
therefor, such Loans will be automatically converted to Base Rate Loans. Each
Notice of Conversion or Continuation shall be irrevocable.

                  2.9. Interest. (a) The Borrower shall pay interest on
the unpaid principal amount of each Loan from the date thereof
until the principal amount thereof shall be paid in full, at the
following rates per annum:

                           (i) For Base Rate Loans, at a rate per annum equal at
                  all times to the Base Rate in effect from time to time plus
                  the Applicable Margin, payable monthly on the first day of
                  each calendar month, on the Termination Date and on the date
                  any Base Rate Loan is converted or paid in full.


                                       37

<PAGE>   45



                           (ii) For Eurodollar Rate Loans, at a rate per annum
                  equal at all times during the applicable Interest Period for
                  each Eurodollar Rate Loan to the sum of the Eurodollar Rate
                  for such Interest Period plus the Applicable Margin in effect
                  on the first day of such Interest Period, payable monthly on
                  the first day of each calendar month and on the Termination
                  Date.

                  (b) If any payment required under the Loan Documents is not
paid within fifteen (15) days after the date such payment is due, then the
Borrower shall pay a "late charge" equal to four percent (4%) of the amount of
that payment to compensate the Lenders for administrative expenses and other
costs of delinquent payments. This late charge shall be immediately due and
payable and shall be in addition to all other rights and remedies available to
the Administrative Agent and the Lenders.

                  (c) Upon the occurrence of an Event of Default and the
continuation thereof, and after the Final Maturity Date or any earlier
acceleration of the Obligations, the Principal Balance, all accrued and unpaid
interest and all other Obligations shall bear interest at a rate that is four
percent (4%) above the rate that would otherwise be payable under the terms
thereof.

                  2.10. Interest Rate Determination and Protection.  (a)
The Eurodollar Rate for each Interest Period for Eurodollar Rate
Loans shall be determined by the Administrative Agent two (2)
Business Days before the first day of such Interest Period.

                  (b) The Administrative Agent shall give prompt notice to the
Borrower and the Lenders of the applicable interest rate determined by the
Administrative Agent for purposes of Section 2.9(a) or (b).

                  (c) If, with respect to Eurodollar Rate Loans, a Lender in
good faith notifies the Administrative Agent that the Eurodollar Rate for any
Interest Period therefor will not adequately reflect the cost to such Lender of
making such Loans or funding or maintaining its Eurodollar Rate Loans for such
Interest Period, the Administrative Agent shall forthwith so notify the Borrower
and the Lenders, whereupon

                           (i)  each Eurodollar Loan will automatically, on
                  the last day of the then existing Interest Period
                  therefor, convert into a Base Rate Loan; and

                           (ii) the obligations of the Lenders to make
                  Eurodollar Rate Loans or to convert Base Rate Loans into
                  Eurodollar Rate Loans shall be suspended until the
                  Administrative Agent shall notify the Borrower that

                                       38

<PAGE>   46



                  such Lender has determined that the circumstances causing such
                  suspension no longer exist.

                  2.11. Increased Costs. If, due to either (i) the introduction
of or any change in or in the interpretation of any law or regulation (other
than any change by way of imposition or increase of reserve requirements
included in determining the Eurodollar Rate Reserve Percentage) or (ii)
compliance with any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law), there shall be
any increase in the cost to any Lender of agreeing to make or making, funding or
maintaining any Eurodollar Rate Loans, then the Borrower shall from time to
time, upon demand by such Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such
increased cost. A certificate as to the amount of such increased cost, submitted
to the Borrower and the Administrative Agent by such Lender, shall be conclusive
and binding for all purposes, absent manifest error. If the Borrower so notifies
the Administrative Agent within five Business Days after any Lender notifies the
Borrower of any increased cost pursuant to the foregoing provisions of this
Section 2.11, the Borrower may either (A) prepay in full all Eurodollar Rate
Loans of such Lender then outstanding in accordance with Section 2.7(b) and,
additionally, reimburse such Lender for such increased cost in accordance with
this Section 2.11 or (B) convert all Eurodollar Rate Loans of all Lenders then
outstanding into Base Rate Loans in accordance with Section 2.8 and,
additionally, reimburse such Lender for such increased cost in accordance with
this Section 2.11.

                  2.12. Illegality. Notwithstanding any other provision of this
Agreement, if the introduction of or any change in or in the interpretation of
any law or regulation shall make it unlawful, or any central bank or other
Governmental Authority shall assert that it is unlawful, for any Lender or its
Eurodollar Lending Office to make Eurodollar Rate Loans or to continue to fund
or maintain Eurodollar Rate Loans, then, on notice thereof and demand therefor
by such Lender to the Borrower through the Administrative Agent, (i) the
obligation of such Lender to make or to continue Eurodollar Rate Loans and to
convert Base Rate Loans into Eurodollar Rate Loans shall terminate and (ii) the
Borrower shall forthwith prepay in full all Eurodollar Rate Loans of such Lender
then outstanding, together with interest accrued thereon, unless the Borrower,
within five (5) Business Days of such notice and demand, converts all Eurodollar
Rate Loans of all Lenders then outstanding into Base Rate Loans.


                                       39

<PAGE>   47



                  2.13. Capital Adequacy. If (i) the introduction of or any
change in or in the interpretation of any law or regulation, (ii) compliance
with any law or regulation, or (iii) compliance with any guideline or request
from any central bank or other Governmental Authority (whether or not having the
force of law) affects or would affect the amount of capital required or expected
to be maintained by any Lender or the Issuing Bank or any corporation
controlling any Lender or the Issuing Bank and such Lender or the Issuing Bank
(as applicable) reasonably determines that such amount is based upon the
existence of such Lender's Commitment and Loans and its other commitments and
loans of this type (or, in the case of the Issuing Bank, the issuance of the
Facility Letters of Credit), then, upon demand by such Lender or the Issuing
Bank (as applicable) (with a copy of such demand to the Administrative Agent),
the Borrower shall pay to the Administrative Agent for the account of such
Lender or the Issuing Bank (as applicable), from time to time as specified by
such Lender or the Issuing Bank (as applicable), additional amounts sufficient
to compensate such Lender or the Issuing Bank (as applicable) in the light of
such circumstances, to the extent that such Lender or the Issuing Bank (as
applicable) reasonably determines such increase in capital to be allocable to
the existence of such Lender's Commitment and Loans (or, in the case of the
Issuing Bank, the issuance of the Facility Letters of Credit). A certificate as
to such amounts submitted to the Borrower and the Administrative Agent by such
Lender or the Issuing Bank (as applicable) shall be conclusive and binding for
all purposes absent manifest error.

                  2.14. Payments and Computations. (a) The Borrower shall make
each payment hereunder and under the Notes not later than 10:00 A.M. (Phoenix
time) on the day when due, in Dollars, to the Administrative Agent at its
address referred to in Section 11.2 in immediately available funds without
set-off or counterclaim. The Administrative Agent will promptly thereafter cause
to be distributed immediately available funds relating to the payment of
principal or interest or fees (other than amounts payable pursuant to Section
2.11, 2.12, 2.13 or 2.15) to the Lenders, in accordance with their respective
Ratable Portions, for the account of their respective Applicable Lending
Offices, and like funds relating to the payment of any other amount payable to
any Lender to such Lender for the account of its Applicable Lending Office, in
each case to be applied in accordance with the terms of this Agreement. To the
extent the foregoing payments are received by the Administrative Agent prior to
10:00 A.M. (Phoenix time) and are not distributed to the Lenders on the same
day, the Administrative Agent shall pay to each Lender in addition to the amount
distributed to such Lender, interest thereon, for each day from the date such
amount is received by the Administrative Agent until the date such amount is
distributed to such Lender, at the Federal Funds Rate. Payment received by the
Administrative Agent

                                       40

<PAGE>   48



after 10:00 A.M. (Phoenix time) shall be deemed to be received on the next
Business Day.

                  (b) The Borrower hereby authorizes each Lender, if and to the
extent payment owed to such Lender is not made when due hereunder or under any
Loan held by such Lender, to charge from time to time against any or all of the
Borrower's accounts with such Lender any amount so due.

                  (c) All computations of interest based on the Base Rate, the
Eurodollar Rate or the Federal Funds Rate and of fees shall be made by the
Administrative Agent on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest and fees are payable. Each
determination by the Administrative Agent of an interest rate hereunder shall be
conclusive and binding for all purposes, absent manifest error.

                  (d) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or fee, as the case
may be; provided, however, that if such extension would cause payment of
interest on or principal of any Eurodollar Rate Loan to be made in the next
calendar month, such payment shall be made on the next preceding Business Day.

                  (e) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due hereunder to the
Lenders that the Borrower will not make such payment in full, the Administrative
Agent may assume that the Borrower has made such payment in full to the
Administrative Agent on such date and the Administrative Agent may, in reliance
upon such assumption, (but shall not be obligated to) cause to be distributed to
each Lender on such due date an amount equal to the amount then due such Lender.
If and to the extent the Borrower shall not have so made such payment in full to
the Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at the Federal Funds Rate.

                  (f) If any Lender (a "Non-Funding Lender") has (x) failed to
make a Loan required to be made by it hereunder, and the Administrative Agent
has determined that such Lender is not likely to make such Loan or (y) given
notice to the Borrower or the Administrative Agent that it will not make, or
that it has

                                       41

<PAGE>   49



disaffirmed or repudiated any obligation to make, Loans, in each case whether by
reason of the provisions of the Financial Institutions Reform, Recovery and
Enforcement Act of 1989 or otherwise, (i) such Non-Funding Lender shall lose any
and all voting rights hereunder, and (ii) any payment made on account of the
principal of the Loans outstanding shall be made as follows:

                           (A) in the case of any such payment made on any date
         when and to the extent that, in the determination of the Administrative
         Agent, the Borrower would be able, under the terms and conditions
         hereof, to reborrow the amount of such payment under the Commitments
         and to satisfy any applicable conditions precedent set forth in Article
         III to such reborrowing, such payment shall be made on account of the
         outstanding Loans held by the Lenders other than the Non-Funding Lender
         pro rata according to the respective outstanding principal amounts of
         the Loans of such Lenders;

                           (B) otherwise, such payment shall be made on account
         of the outstanding Loans held by the Lenders pro rata according to the
         respective outstanding principal amounts of such Loans; and

                           (C) any payment made on account of interest on the
         Loans shall be made pro rata according to the respective amounts of
         accrued and unpaid interest due and payable on the Loans with respect
         to which such payment is being made.

                  2.15. Taxes. (a) Any and all payments by the Borrower under
each Loan Document shall be made free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Lender and the Administrative Agent, taxes measured by its net income,
and franchise taxes imposed on it, by the jurisdiction under the laws of which
such Lender or the Administrative Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Lender, taxes measured by
its net income, and franchise taxes imposed on it, by the jurisdiction of such
Lender's Applicable Lending Office or any political subdivision thereof (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities (excluding, in the case of such Lender or the Administrative Agent,
taxes imposed by reason of any failure of such Lender or the Administrative
Agent, if such Lender or the Administrative Agent is entitled at such time to a
total or partial exemption from withholding that is required to be evidenced by
a United States Internal Revenue Service Form 1001 or 4224 or any successor or
additional form, to deliver to the Administrative Agent or the Borrower, from
time to time as required by the Administrative Agent or the Borrower, such Form

                                       42

1001 or 4224 (as applicable) or any successor or additional form, completed in a
manner reasonably satisfactory to the Administrative Agent or the Borrower)
being hereinafter referred to as "Taxes"). If the Borrower shall be required by
law to deduct any Taxes from or in respect of any sum payable hereunder to any
Lender or the Administrative Agent (i) the sum payable shall be increased as may
be necessary so that after making all required deductions (including, without
limitation, deductions applicable to additional sums payable under this Section
2.15) such Lender or the Administrative Agent (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the
full amount deducted to the relevant taxing authority or other authority in
accordance with applicable law, and (iv) the Borrower shall deliver to the
Administrative Agent evidence of such payment to the relevant taxation or other
authority.

                  (b) In addition, the Borrower agrees to pay any present or
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies of the United States or any political subdivision thereof or
any applicable foreign jurisdiction which arise from any payment made under any
Loan Document or from the execution, delivery or registration of, or otherwise
with respect to, any Loan Document (collectively, but excluding real estate and
personal property taxes, "Other Taxes").

                  (c) The Borrower will indemnify each Lender and the
Administrative Agent for the full amount of Taxes or Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any jurisdiction on
amounts payable under this Section 2.15) paid by such Lender or the
Administrative Agent (as the case may be) and any liability (including, without
limitation, for penalties, interest and expenses) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted. This indemnification shall be made within 30 days from the
date such Lender or the Administrative Agent (as the case may be) makes written
demand therefor.

                  (d) Within 30 days after the date of any payment of Taxes or
Other Taxes, the Borrower will furnish to the Administrative Agent, at its
address referred to in Section 10.2, the original or a certified copy of a
receipt evidencing payment thereof.

                  (e) Without prejudice to the survival of any other agreement
of the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 2.15 shall survive the payment in full of the
Obligations.

                  (f) Prior to the Closing Date in the case of each Lender that
is a signatory hereto, and on the date of the Assignment and Acceptance pursuant
to which it becomes a Lender in the case of each other Lender, and from time to
time thereafter if requested by the Borrower or the Administrative Agent, each
Lender organized under the laws of a jurisdiction outside the United States that
is entitled to an exemption from United States withholding tax, or that is
subject to such tax at a reduced rate under an applicable tax treaty, shall
provide the Administrative Agent and the Borrower with an IRS Form 4224 or Form
1001 or other applicable form, certificate or document prescribed by the IRS
certifying as to such Lender's entitlement to such exemption or reduced rate
with respect to all payments to be made to such Lender hereunder and under the
Notes. Unless the Borrower and the Administrative Agent have received forms or
other documents satisfactory to them indicating that payments hereunder or under
any Note are not subject to United States withholding tax or are subject to such
tax at a rate reduced by an applicable tax treaty, the Borrower or the
Administrative Agent shall withhold taxes from such payments at the applicable
statutory rate in the case of payments to or for any Lender organized under the
laws of a jurisdiction outside the United States.

                  (g) Any Lender claiming any additional amounts payable
pursuant to this Section 2.15 shall use its best efforts (consistent with its
internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Applicable Lending Office if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
which may thereafter accrue and would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

                  2.16. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Loans made by it (other than pursuant
to Sections 2.11, 2.13 or 2.15) in excess of its Ratable Portion of payments on
account of the Loans obtained by all the Lenders, such Lender shall forthwith
purchase from the other Lenders such participations in their Loans as shall be
necessary to cause such purchasing Lender to share the excess payment ratably
with each of them.

                  2.17. Extension of Final Maturity Date. (a) Provided no
Default or Event of Default has occurred that is continuing, the Borrower may
request a one-year extension of the Final Maturity Date by submitting a request
for an extension to the Administrative Agent (an "Extension Request") not more
than eighteen (18) months nor less than fifteen (15) months prior to the then
scheduled Final Maturity Date. Promptly upon (but not

                                       44

<PAGE>   52



later than three (3) Business Days after) receipt of the Extension Request, the
Administrative Agent shall notify each Lender of, and shall request each Lender,
at its election, to approve or disapprove, the Extension Request. Each Lender
approving the Extension Request shall deliver its written approval no later than
thirty (30) days after the date of the Extension Request. If the approval of
each of the Lenders is received by the Administrative Agent within thirty (30)
days of the date of the Extension Request, the Administrative Agent shall
promptly so notify the Borrower and each Lender and the Final Maturity Date
shall be extended by one year, and in such event the Borrower may thereafter
request a further extension of the then scheduled Final Maturity Date in
accordance with this Section 2.17. If any of the Lenders does not deliver to the
Administrative Agent such Lender's written approval to any Extension Request
within thirty (30) days of the date of such Extension Request, the Final
Maturity Date shall not be extended.

                  (b) If all of the Lenders approve an Extension Request
pursuant to Section 2.17(a), the Borrower shall pay to the Administrative Agent,
on or before July 1 of the year in which the Extension Request was delivered,
for the account of each Lender, an extension fee equal to 0.25% times such
Lender's Commitment.

obligations of the Borrower to acquire a Hotel constructed or to be constructed
for the Borrower and permitted to be acquired by the Borrower under the
provisions hereof.

                  4.2. Limitations.  The Issuing Bank shall not issue,

         satisfaction is given to such Issuing Bank by the
         Administrative Agent;

                  (v) that has an expiration date (taking into account any
         automatic renewal provisions thereof) later than thirty (30) days prior
         to the scheduled Termination Date; or

                  (vi) that is in a currency other than U.S. Dollars.

satisfaction of the conditions contained in Sections 3.1 and 3.3,
as applicable, the issuance of any Facility Letter of Credit is

                  (i) the Borrower shall have delivered to the Issuing Bank at
         such times and in such manner as the Issuing Bank may reasonably
         prescribe a Reimbursement Agreement and such other documents and
         materials as may be reasonably required pursuant to the terms thereof,
         and the proposed Facility Letter of Credit shall be reasonably
         satisfactory to such Issuing Bank in form and content; and

                  (ii) as of the Issuance Date no order, judgment or decree of
         any court, arbitrator or governmental authority shall enjoin or

                                       57

<PAGE>   65



                  (b) Within ten (10) days after receipt of a request for
issuance of a Facility Letter of Credit in accordance with Section 4.4(a), the
Issuing Bank shall approve or disapprove, in its reasonable discretion, the
issuance of such requested Facility Letter of Credit, but the issuance of such
approved Facility Letter of Credit shall continue to be subject to the
provisions of this Article IV.

                  (c) Not less than four (4) nor more than six (6) Business Days
prior to the issuance of a Facility Letter of Credit approved by the Issuing
Bank as provided in Section 4.4(b), the Borrower shall confirm in writing to the
Administrative Agent and to the Issuing Bank the intended Issuance Date and
amount of such Facility Letter of Credit. Provided the issuance of the requested
Facility Letter of Credit would be permitted under the provisions of Section
4.2(iii) and that the applicable conditions set forth in Sections 3.1 and 3.3
have been satisfied, then, subject to the terms and conditions of this Article
IV, the Issuing Bank shall, on the requested Issuance Date, issue the requested
Facility Letter of Credit in accordance with the Issuing Bank's usual and
customary business practices. The Issuing Bank shall give the Administrative
Agent written notice, or telephonic notice confirmed promptly thereafter in
writing, of the issuance of a Facility Letter of Credit.

                  (d) The Issuing Bank shall not extend or amend any Facility
Letter of Credit unless the requirements of this Section 4.4 are met as though a
new Facility Letter of Credit were being requested and issued.

                  (e) Any Lender may, but shall not be obligated to, issue to
Sunstone, the Borrower or any of their Subsidiaries Letters of Credit (that are
not Facility Letters of Credit) for its own account, and at its own risk. None
of the provisions of this Article IV shall apply to any Letter of Credit that is
not a Facility Letter of Credit.

                  4.5. Duties of Issuing Bank. Any action taken or omitted to be
taken by an Issuing Bank under or in connection with any Facility Letter of
Credit, if taken or omitted in the absence of willful misconduct or gross
negligence, shall not put such Issuing Bank under any resulting liability to any
Lender or, assuming that such Issuing Bank has complied with the procedures
specified in Section 4.4, relieve any Lender of its obligations hereunder to
such Issuing Bank. In determining whether to pay under any Facility Letter of
Credit, the Issuing Bank shall have no obligation relative to the Lenders other
than to confirm that any documents required to be delivered under such Facility
Letter of Credit appear to have been delivered in compliance and that

                                       58

<PAGE>   66



they appear to comply on their face with the requirements of such Facility
Letter of Credit.

                  4.6. Participation. (a) Immediately upon issuance by an
Issuing Bank of any Facility Letter of Credit in accordance with Section 4.4,
each Lender shall be deemed to have irrevocably and unconditionally purchased
and received from such Issuing Bank, without recourse or warranty, an undivided
interest and participation ratably in such Facility Letter of Credit (including,
without limitation, all obligations of the Borrower with respect thereto other
than amounts owing to such Issuing Bank under Section 2.13).

                  (b) In the event that an Issuing Bank makes any payment under
any Facility Letter of Credit and the Borrower shall not have repaid such amount
to such Issuing Bank on or before the date of such payment by such Issuing Bank,
such Issuing Bank shall promptly so notify the Administrative Agent, which shall
promptly so notify each Lender. Upon receipt of such notice, each Lender shall
promptly and unconditionally pay to the Administrative Agent for the account of
such Issuing Bank the amount of such Lender's Ratable Share of such payment in
same day funds, and the Administrative Agent shall promptly pay such amount, and
any other amounts received by the Administrative Agent for such Issuing Bank's
account pursuant to this Section 4.6(b), to such Issuing Bank. If the
Administrative Agent so notifies such Lender prior to 10:00 A.M. (Phoenix time)
on any Business Day, such Lender shall make available to the Administrative
Agent for the account of such Issuing Bank such Lender's Ratable Share of the
amount of such payment on such Business Day in same day funds. If and to the
extent such Lender shall not have so made its Ratable Share of the amount of
such payment available to the Administrative Agent for the account of such
Issuing Bank, such Lender agrees to pay to the Administrative Agent for the
account of such Issuing Bank forthwith on demand such amount, together with
interest thereon, for each day from the date such payment was first due until
the date such amount is paid to the Administrative Agent for the account of such
Issuing Bank, at the Federal Funds Rate. The failure of any Lender to make
available to the Administrative Agent for the account of such Issuing Bank such
Lender's Ratable Share of any such payment shall not relieve any other Lender of
its obligation hereunder to make available to the Administrative Agent for the
account of such Issuing Bank its Ratable Share of any payment on the date such
payment is to be made.

                  (c) The payments made by the Lenders to an Issuing Bank in
reimbursement of amounts paid by it under a Facility Letter of Credit shall
constitute, and the Borrower hereby expressly acknowledges and agrees that such
payments shall constitute, Loans hereunder and such payments shall for all

                                       59

<PAGE>   67



purposes be treated as Advances (notwithstanding that the amounts thereof may
not comply with the provisions of Section 2.3). Such Loans shall be Base Rate
Loans, subject to the Borrower's rights under Article II hereof.

                  (d) Upon the request of the Administrative Agent or any
Lender, an Issuing Bank shall furnish to the requesting Administrative Agent or
Lender copies of any Facility Letter of Credit or Reimbursement Agreement to
which such Issuing Bank is party and such other documentation as may reasonably
be requested by the Administrative Agent or the Lender.

                  (e) The obligations of the Lenders to make payments to the
Administrative Agent for the account of an Issuing Bank with respect to a
Facility Letter of Credit shall be irrevocable, not subject to any qualification
or exception whatsoever and shall be made in accordance with, but not subject
to, the terms and conditions of this Agreement under all circumstances,
notwithstanding:

                  (i) any lack of validity or enforceability of this Agreement
         or any of the other Loan Documents;

                  (ii) the existence of any claim, setoff, defense or other
         right which the Borrower may have at any time against a beneficiary
         named in a Facility Letter of Credit or any transferee of any Facility
         Letter of Credit (or any Person for whom any such transferee may be
         acting), such Issuing Bank, the Administrative Agent, any Lender, or
         any other Person, whether in connection with this Agreement, any
         Facility Letter of Credit, the transactions contemplated herein or any
         unrelated transactions (including any underlying transactions between
         the Borrower or any Subsidiary and the beneficiary named in any
         Facility Letter of Credit);

                  (iii) any draft, certificate or any other document presented
         under the Facility Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect of any statement therein being
         untrue or inaccurate in any respect;

                  (iv) the surrender or impairment of any security for the
         performance or observance of any of the terms of any of the Loan
         Documents;

                  (v) any failure by the Administrative Agent or the Issuing
         Bank to make any reports required pursuant to Section 4.8; or

                  (vi) the occurrence of any Default or Event of Default.

                                       60

<PAGE>   68



                  4.7. Compensation for Facility Letters of Credit. (a) The
Borrower agrees to pay to the Administrative Agent, in the case of each
outstanding Facility Letter of Credit, the Facility Letter of Credit Fee
therefor, payable in quarterly installments in advance on the Issuance Date
(which installment shall be a pro rata portion of the annual Facility Letter of
Credit Fee for the period commencing on the Issuance Date and ending on the last
day of the calendar quarter in which the Issuance Date occurs) and on the first
day of each calendar quarter after the Issuance Date (which installment shall be
a pro rata portion of the annual Facility Lease of Credit Fee for the quarter in
which such payment is due). Facility Letter of Credit Fees shall be calculated,
on a pro rata basis for the period to which such payment applies, for actual
days that will elapse during such period, on the basis of a 360-day year. The
Administrative Agent shall promptly remit such Facility Letter of Credit Fees,
when paid, to the Lenders ratably. Each installment of the Facility Letter of
Credit Fee shall be fully earned on the date on which such installment is
payable and shall not be refundable if the Facility Letter of Credit is
thereafter returned to the Issuing Bank or otherwise canceled prior to its
expiration date.

                  (b) An Issuing Bank shall have the right to receive solely for
its own account such amounts as the Borrower may agree to pay to such Issuing
Bank with respect to issuance fees and for such Issuing Bank's out-of-pocket
costs of issuing and servicing Facility Letters of Credit.

                  4.8. Issuing Bank Reporting Requirements. The Issuing Bank
shall, no later than the tenth day following the last day of each month, provide
to the Administrative Agent a schedule of the Facility Letters of Credit issued
by it showing the Issuance Date, account party, original face amount, amount (if
any) paid thereunder, expiration date and the reference number of each Facility
Letter of Credit outstanding at any time during such month and the aggregate
amount (if any) payable by the Borrower to such Issuing Bank during the month
pursuant to Section 2.13. Copies of such reports shall be provided promptly to
each Lender by the Administrative Agent.

                  4.9. Indemnification; Nature of Issuing Bank's Duties. (a) In
addition to amounts payable as elsewhere provided in this Article IV, the
Borrower hereby agrees to protect, indemnify, pay and save the Administrative
Agent, the Issuing Bank and each Lender harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees) arising from the claims of third parties
against the Administrative Agent, the Issuing Bank or any Lender as a
consequence, direct or indirect, of (i) the issuance of any Facility Letter of
Credit other than, in the case of the Issuing Bank, as a result of its willful
misconduct or

                                       61

<PAGE>   69



gross negligence, or (ii) the failure of an Issuing Bank issuing a Facility
Letter of Credit to honor a drawing under such Facility Letter of Credit as a
result of any act or omission, whether rightful or wrongful, of any Governmental
Authority.

                  (b) As among the Borrower, the Lenders, the Administrative
Agent and the Issuing Bank, the Borrower assumes all risks of the acts and
omissions of, or misuse of Facility Letters of Credit by, the respective
beneficiaries of such Facility Letters of Credit. In furtherance and not in
limitation of the foregoing, neither the Issuing Bank nor the Administrative
Agent nor any Lender shall be responsible: (i) for the form, validity,
sufficiency, accuracy, genuineness or legal effect of any document submitted by
any party in connection with the application for and issuance of the Facility
Letters of Credit, even if it should in fact prove to be in any or all respects
invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the validity
or sufficiency of any instrument transferring or assigning or purporting to
transfer or assign a Facility Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) for failure of the beneficiary of a
Facility Letter of Credit to comply fully with conditions required in order to
draw upon such Facility Letter of Credit; (iv) for errors, omissions,
interruptions or delays in transmission or delivery of any messages, by mail,
cable, telegraph, telex, facsimile transmission or otherwise; (v) for errors in
interpretation of technical terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any Facility Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of a Facility Letter of Credit of the proceeds
of any drawing under such Facility Letter of Credit; and (viii) for any
consequences arising from causes beyond the control of the Administrative Agent,
the Issuing Bank and the Lenders including, without limitation, any act or
omission, whether rightful or wrongful, of any Governmental Authority. None of
the above shall affect, impair, or prevent the vesting of any of the Issuing
Bank's rights or powers under this Section 4.9.

                  (c) In furtherance and extension and not in limitation of the
specific provisions hereinabove set forth, any action taken or omitted by an
Issuing Bank under or in connection with the Facility Letters of Credit or any
related certificates, if taken or omitted in good faith, shall not put such
Issuing Bank, the Administrative Agent or any Lender under any resulting
liability to the Borrower or relieve the Borrower of any of its obligations
hereunder to any such Person.

                  (d)  Notwithstanding anything to the contrary contained
in this Section 4.9, the Borrower shall have no obligation to

                                       62

<PAGE>   70



indemnify an Issuing Bank under this Section 4.9 in respect of any liability
incurred by such Issuing Bank arising primarily out of the willful misconduct or
gross negligence of such Issuing Bank, as determined by a court of competent
jurisdiction, or out of the wrongful dishonor by such Issuing Bank of a proper
demand for payment made under the Facility Letters of Credit issued by such
Issuing Bank, unless such dishonor was made at the request of the Borrower.

                  4.10. Resignation of Issuing Bank. The Issuing Bank shall
continue to be the Issuing Bank unless and until (i) it shall have given the
Borrower and the Administrative Agent notice that it has elected to resign as
Issuing Bank and (ii) another Lender shall have agreed to be the replacement
Issuing Bank and shall have been approved in writing by the Administrative Agent
and the Borrower. The resigning Issuing Bank shall continue to have the rights
and obligations of an Issuing Bank hereunder solely with respect to Facility
Letters of Credit theretofore issued by it notwithstanding the designation of a
replacement Issuing Bank hereunder), but upon such designation of a replacement
Issuing Bank, the resigning Issuing Bank shall not thereafter issue any Facility
Letters of Credit (unless it shall again thereafter be designated as Issuing
Bank in accordance with the provisions of this Section 4.10).

                  4.11. Obligations of Issuing Bank and Other Lenders. Except to
the extent that a Lender shall have agreed to be designated as an Issuing Bank,
no Lender shall have any obligation to accept or approve any request for, or to
issue, amend or extend, any Letter of Credit, and the obligations of the Issuing
Bank to issue, amend or extend any Facility Letter of Credit are expressly
limited by and subject to the provisions of this Article IV.

                  4.12. Issuing Bank's Rights. All of the representations,
warranties, covenants and agreements of the Borrower to the Lenders under this
Agreement and of the Borrower or any other Loan Party under any other Loan
Document shall inure to the benefit of the Issuing Bank (unless the context
otherwise indicates).

transactions contemplated thereby, and no financial statement delivered pursuant
hereto or thereto, contains any untrue statement of a material fact or omits to
state a material fact necessary to make the statements contained herein or
therein not misleading.

                  5.5. Financial Matters. (a) The consolidated balance sheet of
Sunstone and its Subsidiaries as at December 31, 1996, and the related
consolidated statements of income, retained earnings and cash flows of Sunstone
and its Subsidiaries for the fiscal year then ended, certified by Coopers &
Lybrand, LLP, copies of which have been furnished to each Lender, fairly present
the consolidated financial condition of Sunstone and its Subsidiaries as at such
dates and the consolidated results of the operations of Sunstone and its
Subsidiaries for the period ended on such dates, all in conformity with GAAP.

                  (b) Since December 31, 1996, there has been no Material
Adverse Change and there have been no events or developments that in the
aggregate have had a Material Adverse Effect.

                  (c) Neither Sunstone nor any of its Subsidiaries had at
December 31, 1996 any material obligation, contingent liability or liability for
taxes, long-term leases or unusual forward or long-term commitment which is not
reflected in the balance sheet at such date referred to in subsection (a) above
or in the notes thereto.

                  (d) The Projections that have been delivered to each Lender
were prepared on the basis of the assumptions expressed therein, which
assumptions the Borrower believed to be reasonable based on the information
available to the Borrower at the time so furnished and on the Closing Date.


                                       66

                  (e) Sunstone is, the Borrower is, and on a consolidated basis
Sunstone and its Subsidiaries are, Solvent.

                  5.6. Litigation. There are no pending or, to the knowledge of
the Borrower, threatened actions, investigations or proceedings affecting
Sunstone, the Borrower, any of their respective Subsidiaries or (to the best
knowledge of the Borrower) the Operating Lessee or Manager or any of their
respective properties or revenues before any court, Governmental Authority or
arbitrator, other than those that in the aggregate, if adversely determined,
would have no Material Adverse Effect. The performance of any action by (a) any
Loan Party required or contemplated by any of the Loan Documents or (b) any
Operator required or contemplated by any Operating Lease or Management Agreement
is not, to the best knowledge of the Borrower, restrained or enjoined (either
temporarily, preliminarily or permanently), and, to the best knowledge of the
Borrower, no material adverse condition has been imposed by any Governmental
Authority or arbitrator upon any of the foregoing transactions contemplated by
the aforementioned documents.

                  5.7. Margin Regulations. The Borrower is not engaged in the
business of extending credit for the purpose of purchasing or carrying margin
stock (within the meaning of Regulation U issued by the Board of Governors of
the Federal Reserve System), and no proceeds of any Borrowing will be used to
purchase or carry any margin stock or to extend credit to others for the purpose
of purchasing or carrying any margin stock.

                  5.8. Ownership. (a) As of the Closing Date, the authorized
capital stock of Sunstone consists of (i) 50,000,000 shares of common stock,
$.01 par value per share, of which 16,250,244 shares are issued and outstanding
as of the date hereof, and (ii) 10,000,000 shares of preferred stock, $.01 par
value per share, of which no shares are outstanding as of the date hereof. All
of the outstanding capital stock of Sunstone has been validly issued, is fully
paid and non-assessable. As of the Closing Date, 443,961 shares of Sunstone's
common stock, and/or units of limited partnership interests in the Borrower that
are redeemable for common stock of Sunstone are owned, in the aggregate,
beneficially by Alter, free and clear of all Liens.

                  (b) Sunstone is the sole general partner of Borrower and, as
of the Closing Date, owns beneficially and of record at least 85% of the
partnership interests of Borrower free and clear of all Liens.

                  (c) Set forth on Schedule 5.8 hereto is a complete and
accurate list showing, as of the date hereof, all Subsidiaries and
Unconsolidated Entities of Sunstone and of the Borrower and,

                                       67

<PAGE>   75



as to each such Subsidiary and Unconsolidated Entity, the jurisdiction of its
formation and the percentage of the outstanding Stock of each class owned
(directly or indirectly) by the Borrower. No Stock of any Subsidiary or
Unconsolidated Entity of the Borrower is subject to any outstanding option,
warrant, right of conversion or purchase or any similar right. All of the
outstanding capital Stock of each such Subsidiary and Unconsolidated Entity
owned by Sunstone or the Borrower has been validly issued, is fully paid and
(except for partnership interests) non-assessable, and all outstanding capital
Stock of its Subsidiaries and Unconsolidated Entities owned by the Sunstone or
the Borrower is free and clear of all Liens. Neither Sunstone nor the Borrower
nor any such Subsidiary or Unconsolidated Entity is a party to, or has knowledge
of, any agreement restricting the transfer or hypothecation of any shares of
Stock of any such Subsidiary or Unconsolidated Entity, other than those imposed
by Requirements of Law, or the Loan Documents.

                  (d) As of the Closing Date, Alter owns (i) 100% of the issued
and outstanding common stock of the Manager and (ii) 80% of the issued and
outstanding common stock of the Operating Lessee.

                  5.9. ERISA. (a) There are no Multiemployer Plans.

                  (b) Each Plan and any related trust intended to qualify under
Code Section 401 or 501 has been determined by the IRS to be so qualified and to
the best knowledge of the Borrower nothing has occurred which would cause the
loss of such qualification.

                  (c) None of Sunstone, the Borrower, any of their respective
Subsidiaries or any ERISA Affiliate, with respect to any Pension Plan, has
failed to make any contribution or pay any amount due as required by Section 412
of the Code or Section 302 of ERISA or the terms of any such plan, and all
required contributions and benefits have been paid in accordance with the
provisions of each such plan.

                  (d) There are no pending or, to the knowledge of the Borrower,
threatened claims, actions or proceedings (other than claims for benefits in the
normal course), relating to any Plan other than those that in the aggregate, if
adversely determined, would have no Material Adverse Effect.

                  (e) No Pension Plan has any unfunded accrued benefit
liabilities, as determined by using reasonable actuarial assumptions utilized by
such plan's actuary for funding purposes. Within the last five years none of
Sunstone, the Borrower, any of their respective Subsidiaries or any ERISA
Affiliate has caused a Pension Plan with any such liabilities to be transferred
outside

                                       68

<PAGE>   76



of its "controlled group" (within the meaning of Section 4001(a)(14) of ERISA).

                  (f) No Plan provides for continuing health, disability,
accident or death benefits or coverage for any participant or his or her
beneficiary after such participant's termination of employment (except as may be
required by Section 4980B of the Code and at the sole expense of the participant
or the beneficiary) which would result in the aggregate under all Plans in a
liability in an amount which would have a Material Adverse Effect.

                  (g) None of the assets of any of the Loan Parties are subject
to Title I of ERISA because they consist of "plan assets" within the meaning of
DOL Regulation Section 2510.3-101 by reason of an equity investment in any of
the Loan Parties.

                  5.10. Indebtedness. Except as disclosed on Schedule 5.10, as
of the date hereof, none of Sunstone, the Borrower or any of their respective
Subsidiaries or Unconsolidated Entities has any Indebtedness.

                  5.11. Dividends and Distributions. From and after the Closing
Date, Sunstone has not declared or made any dividends or distributions that are
not permitted pursuant to Section 6.7.

                  5.12. No Burdensome Restrictions; No Defaults. (a) No Loan
Party nor any of its Subsidiaries (i) is a party to any Contractual Obligation
the compliance with which would have a Material Adverse Effect or the
performance of which by any thereof, either unconditionally or upon the
happening of an event, will result in the creation of a Lien on the property or
assets of any such Loan Party or its Subsidiaries, or (ii) is subject to any
charter or corporate restriction which has a Material Adverse Effect.

                  (b) No Loan Party or Subsidiary of any Loan Party is in
default under or with respect to any Contractual Obligation owed by it and, to
the knowledge of the Borrower, no other party is in default under or with
respect to any Contractual Obligation owed to any Loan Party or to any
Subsidiary of a Loan Party, other than those defaults which in the aggregate
have no Material Adverse Effect.

                  (c) No Event of Default or Default has occurred and is
continuing.

                  (d) There is no Requirement of Law the compliance with which
by any Loan Party would have a Material Adverse Effect.

<PAGE>   77



                  (e) As of the date hereof, no Subsidiary of Sunstone or the
Borrower (other than single-asset or bankruptcy remote entities) is subject to
any Contractual Obligation (other than as set forth in the governing documents
thereof) restricting or limiting its ability to transfer its assets to Sunstone
or the Borrower (as applicable) or to declare or make any dividend payment or
other distribution on account of any shares of any class of its Stock or its
ability to purchase, redeem, or otherwise acquire for value or make any payment
in respect of any such shares or any shareholder rights.

                  5.13. Investments. Except as disclosed on Schedule 5.8 or
Schedule 5.13, Sunstone, the Borrower and their respective Subsidiaries
considered as a single enterprise, are not engaged in any joint venture or
partnership with any other Person and do not maintain any Investment, as of the
date hereof.

                  5.14. Government Regulation. Neither Sunstone, nor the
Borrower nor any of their respective Subsidiaries is an "investment company" or
an "affiliated person" of, or "promoter" or "principal underwriter" for, an
"investment company", as such terms are defined in the Investment Company Act of
1940, as amended, or subject to regulation under the Public Utility Holding
Company Act of 1935, the Federal Power Act, the Interstate Commerce Act, or any
other federal or state statute or regulation such that its ability to incur
Indebtedness is limited, or its ability to consummate the transactions
contemplated hereby or by any other Loan Document, or the exercise by the
Administrative Agent or any Lender of rights and remedies hereunder or
thereunder, is impaired. The making of the Loans by the Lenders, the application
of the proceeds and repayment thereof by the Borrower and the consummation of
the transactions contemplated by the Loan Documents will not cause Sunstone, the
Borrower or any of their respective Subsidiaries to violate any provision of any
of the foregoing or any rule, regulation or order issued by the Securities and
Exchange Commission thereunder.

                  5.15. Insurance. All policies of insurance of any kind or
nature owned by or issued to or for the benefit of any Loan Party (other than
any individual) or any of its Subsidiaries, or issued in respect of any real
property owned or leased by the Borrower or any of its Subsidiaries including,
without limitation, policies of life, fire, theft, product liability, public
liability, property damage, other casualty, employee fidelity, workers,
compensation and employee health and welfare insurance, are in full force and
effect and are of a nature and provide such coverage as is sufficient and as is
customarily carried by companies of the size and character of such Person. No
Loan Party (other than any individual) or any of its Subsidiaries has been
refused insurance for which it applied or

                                       70

<PAGE>   78



had any policy of insurance terminated (other than at its request).

                  5.16. Labor Matters. (a) There are no strikes, work stoppages,
slowdowns or lockouts pending or threatened against or involving Sunstone, the
Borrower or their respective Subsidiaries or their respective Hotels, other than
those which in the aggregate have no Material Adverse Effect.

                  (b) There are no unfair labor practice charges, arbitrations
or grievances pending against or involving, or to the knowledge of the Borrower,
threatened against or involving Sunstone, the Borrower or their respective
Subsidiaries, other than those which, in the aggregate, if resolved adversely to
Sunstone, the Borrower or such Subsidiary, would have no Material Adverse
Effect.

                  (c) As of the Closing Date, neither Sunstone, the Borrower nor
any of their respective Subsidiaries is a party to, or has any obligations
under, any collective bargaining agreement.

                  (d) There is no organizing activity involving Sunstone, the
Borrower or any of their respective Subsidiaries pending or, to the Borrower's
knowledge, threatened by any labor union or group of employees, other than those

representation proceedings pending or, to the Borrower's knowledge, threatened
with the National Labor Relations Board, and no labor organization or group of
employees of Sunstone, the Borrower or any of their respective Subsidiaries have
made a pending demand for recognition, other than those which in the aggregate
have no Material Adverse Effect.

                  5.17. Force Majeure. Neither the business nor the properties
of any Loan Party or any of their respective Subsidiaries are currently
suffering from the effects of any fire, explosion, accident, strike, lockout or
other labor dispute, drought, storm, hail, earthquake, embargo, act of God or of
the public enemy or other casualty (whether or not covered by insurance), other
than those which in the aggregate have no Material Adverse Effect.

                  5.18. Use of Proceeds. The proceeds of the Loans will be used
by the Borrower solely as follows: (a) in the case of the initial Loans, to pay
in full all amounts owing the lenders under the Loan Agreement dated June 21,
1996 between the Borrower and Bank One (and partially assigned by Bank One to
Credit Lyonnais) (upon which payment the rights and obligations of the parties
under such loan agreement shall terminate), (b) subject to the limitations set
forth herein, to fund any direct or indirect

                                       71

investment in or renovation of existing Hotels, in Hotels and/or interests in

                  5.19. Environmental Protection. Except as disclosed on
Schedule 5.19 (and the Borrower represents and warrants to the Lenders and the
Administrative Agent that the matters disclosed in the reports identified on
Schedule 5.19 would not reasonably be expected to have a Material Adverse
Effect):

                  (a) to the best knowledge of Borrower, all real property
leased or owned by Sunstone, the Borrower or any of their respective

Liabilities and Costs of $1,000,000 or more;

                  (d) (i) Sunstone, the Borrower and their Subsidiaries and all

<PAGE>   80



Borrower, threatened to revoke, or alleging the violation of, such Environmental
Permits, and (iii) neither Sunstone nor the Borrower nor any of their respective
Subsidiaries or, to the best knowledge of the Borrower, the Operators have
received any notice from any source to the effect that there is lacking any
Environmental Permit required in connection with the current use or operation of
any property leased or owned by Sunstone, the Borrower or any of their
respective Subsidiaries;

                  (e) neither Sunstone nor the Borrower's nor any of their

of any Hazardous Material;

                  (f) neither Sunstone, nor the Borrower nor any of their

subject to any pending Legal Proceeding alleging the violation of any
Environmental Law with respect to a Hotel nor, to the best knowledge of the

their respective Subsidiaries or, to the best knowledge of the Borrower, of any
Operator's, or, to the best knowledge of the Borrower, of any owner of premises
leased by Sunstone, the Borrower or any of their respective Subsidiaries,
involve or previously involved the generation, transportation, treatment,

                                       73

<PAGE>   81



property leased or owned by Sunstone, the Borrower or any of their respective

right of first refusal, or other contractual right to purchase or acquire, or
any Contractual Obligation to effect an Asset Sale of, any Hotel owned or leased
by the Borrower or any of its Subsidiaries, except those that in the aggregate
would not have a Material Adverse Effect whether or not exercised.

                  5.21. Intellectual Property. The Borrower, its Subsidiaries or
the Operating Lessee own or license or otherwise have the right to use all
material licenses, permits, patents, patent applications, trademarks, trademark
applications, service marks, trade names, copyrights, copyright applications,
franchises, authorizations and other intellectual property rights that are
necessary for the operations of their respective businesses, without
infringement upon or conflict with the rights of any other Person with respect
thereto, including, without limitation, the Licenses and all trade names
associated with any private label brands of the Borrower or any of its
Subsidiaries. To the best knowledge of the Borrower, no material slogan or other
advertising device, product, process, method, substance, part or component, or
other material now employed, or now contemplated to be employed, by Sunstone,
the Borrower or any of their respective Subsidiaries or the Operating Lessee
infringes upon or conflicts with any rights owned by any other Person, and no
claim or litigation regarding any of the foregoing is pending or threatened.

                  5.22. Title. (a) The Borrower or its applicable Subsidiary,
owns good and marketable fee simple absolute title to all of the Real Estate
purported to be owned by it, which Real Estate is at the date hereof described
in Schedule 5.22(a), and good and marketable title to, or valid leasehold
interests in, all other properties and assets purported to be leased by the
Borrower or any of its Subsidiaries, including, without limitation, valid
leasehold interests pursuant to the Leases and all property reflected in the
balance sheet referred to in Section 5.5(a). Each Loan Party and its respective
Subsidiaries received all deeds, assignments, waivers, consents, non-disturbance
and recognition or similar agreements, bills of sale

                                       74

<PAGE>   82



and other documents, and have duly effected all recordings, filings and other
actions necessary to establish, protect and perfect the Borrower's and its
Subsidiaries' right, title and interest in and to all such property except for
such documents or actions the failure to obtain or accomplish which would not
have a Material Adverse Effect.

                  (b) All material real property leased at the date hereof by
the Borrower or any of its Subsidiaries is listed on Schedule 5.22(b). Each of
such Leases is valid and enforceable against the Borrower or such Subsidiary (as
applicable) in accordance with its terms and is in full force and effect. The
Borrower has delivered to the Administrative Agent true and complete copies of
each of such Leases and all documents affecting the rights or obligations of the
Borrower or any of its Subsidiaries which is a party thereto, including, without
limitation, any non-disturbance and recognition agreements, subordination
agreements, attornment agreements and agreements regarding the term or rental of
any of the Leases. None of the Borrower or any of its Subsidiaries nor, to the
knowledge of the Borrower, any other party to any such Lease is in default of
its obligations thereunder or has delivered or received any notice of default
under any such Lease, nor has any event occurred which, with the giving of
notice, the passage of time or both, would constitute a default under any such
Lease, except for defaults which in the aggregate have no Material Adverse
Effect.

                  (c) To the knowledge of the Borrower, all components of all
improvements included within the Hotels owned or leased, as lessee, by the
Borrower or any of its Subsidiaries (collectively, "Improvements"), including,
without limitation, the roofs and structural elements thereof and the heating,
ventilation, air conditioning, plumbing, electrical, mechanical, sewer, waste
water, storm water, paving and parking equipment, systems and facilities
included therein, are in good working order and repair, subject to such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect. All water, gas, electrical, steam, compressed air,
telecommunication, sanitary and storm sewage lines and systems and other similar
systems serving the Hotels owned or leased by the Borrower or any of its
Subsidiaries are installed and operating and are sufficient to enable the real
property owned or leased by the Borrower and its Subsidiaries to continue to be
used and operated in the manner currently being used and operated, and the
Borrower has no knowledge of any factor or condition that reasonably could be
expected to result in the termination or material impairment of the furnishing
thereof. No Improvement or portion thereof is dependent for its access,
operation or utility on any land, building or other Improvement not included in
the real property owned or leased by the Borrower or any of its Subsidiaries
other than for access provided

                                       75

<PAGE>   83



pursuant to a recorded easement or other right of way establishing the right of
such access.

                  (d) All Permits required to have been issued or appropriate to
enable all real property owned or leased by the Borrower or any of its
Subsidiaries to be lawfully occupied and used for all of the purposes for which
they are currently occupied and used have been lawfully issued and are in full
force and effect, other than those which in the aggregate have no Material
Adverse Effect.

                  (e) Neither the Borrower nor any of its Subsidiaries has
received any notice, or has any knowledge, of any pending, threatened or
contemplated condemnation proceeding affecting any real property owned or leased
by the Borrower or any of its Subsidiaries or any part thereof, or any proposed
termination or impairment of any parking at any such owned or leased real
property or of any sale or other disposition of any real property owned or
leased by the Borrower or any of its Subsidiaries or any part thereof in lieu of
condemnation, which in the aggregate, are reasonably likely to have a Material
Adverse Effect.

                  (f) Except for events or conditions not reasonably likely to
have, in the aggregate, a Material Adverse Effect, (i) no portion of any real
property owned or leased by the Borrower or any of its Subsidiaries has suffered
any material damage by fire or other casualty loss which has not heretofore been
completely repaired and restored to its condition prior to such casualty, and
(ii) no portion of any real property owned or leased by the Borrower or any of
its Subsidiaries is located in a special flood hazard area as designated by any
Federal Governmental Authorities.

                  5.23. Status as REIT. Sunstone (a) is organized in conformity
with the requirements for qualification as a REIT under the Code, (b) has met
all of the requirements for qualification as a REIT under the Code for its
Fiscal Year most recently ended and (c) is in a position to qualify for its
current Fiscal Year as a REIT under the Code and its proposed methods of
operation will enable it to so qualify.

                  5.24. Operator: Compliance with Law. Each Operator (i) has
full power and authority and the legal right to lease (or sublease), manage or
operate (as applicable) the properties it operates and to conduct the business
in which it is currently engaged with respect to any real property owned or
leased by the Borrower or any of its Subsidiaries, (ii) is duly qualified or
licensed and is in good standing under the laws of each jurisdiction where its
ownership, lease (or sublease), management or operation of any real property
owned or leased by the Borrower or any of its Subsidiaries requires such
qualification, and (iii)

                                       76

is in compliance with all Requirements of Law applicable to the real property
owned or leased by the Borrower or any of its Subsidiaries, or applicable to the
operation or management thereof except to the extent that the failure to comply
therewith is not reasonably likely to have, in the aggregate, a Material Adverse
Effect.

                  5.25. Operating Leases, Licenses and Management Agreement. (a)
Each of the Hotels owned by the Borrower or any of its Subsidiaries (whether
located on land owned by or leased to the Borrower or such Subsidiary) (i) is
leased by the Borrower or its Subsidiary to the Operating Lessee under an
Operating Lease, (ii) is the subject of a License (except as otherwise provided
in subparagraph (i)(E)(3) of the definition of "Eligible Hotel"), and (iii) is
managed and operated for the Operating Lessee by the Manager pursuant to a
Management Agreement.

                  (b) Each of the Operating Leases, Licenses and Management
Agreements in respect of the Hotels owned or leased (as lessee) by the Borrower
or any of its Subsidiaries (i) is in full force and effect, (ii) is a legally
valid and binding obligation of each of the parties thereto, subject to such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect, and (iii) has not been modified, amended or supplemented in any
material or adverse way. Neither the Borrower nor any of its Subsidiaries has
collected any rents becoming due under any Operating Lease more than thirty (30)
days in advance. All rent and other sums and charges payable by any Operating
Lessee under each Operating Lease to which it is a party are current, no notice
of default or termination under any such Operating Lease is outstanding, no
termination event or condition or uncured default on the part of the Operating
Lessee exists under any Operating Lease, and no event of default has occurred
which, with the giving of notice or the lapse of time or both, would constitute
such a default or termination event or condition or uncured default on the part
of the Borrower or its Subsidiaries or the Operators (as the case may be),
subject to such exceptions which are not reasonably likely to have, in the
aggregate, a Material Adverse Effect. As to all of the Leases, Borrower and each
of its Subsidiaries has performed all of its repair and maintenance obligations
(if any) and each Operating Lessee under each Operating Lease to which it is a
party has performed all of its repair and maintenance obligations, subject to
such exceptions which are not reasonably likely to have, in the aggregate, a
Material Adverse Effect.

Eligible Hotels for the purposes of the Borrowing Base as of the Closing Date
and acknowledge that, to the extent that the Borrower has not heretofore
furnished to the Lenders the Eligible Hotel Documents with respect to the
Eligible Hotels listed on Schedule 7.23, such requirement is waived, provided,
however, that, if for any reason any Hotel listed on Schedule 7.23 shall cease
to be an Eligible Hotel but the Borrower shall thereafter desire to have the
Administrative Agent accept such Hotel as an Eligible Hotel, the provisions of
Section 7.23(f) shall apply and provided further that the provisions of this
Section 7.23(a) shall not limit or otherwise affect the obligations (if

may make physical and other verifications of any Hotels included as Eligible
Hotels in any reasonable manner and through any medium that the Administrative
Agent considers advisable, and the Borrower shall furnish all such assistance
and information as the Administrative Agent may require in connection therewith.

                  (e) Notwithstanding anything to the contrary set forth herein,
a Hotel shall cease to be an Eligible Hotel if at any time it, or it,

Borrower thereafter desires that the Administrative Agent accept such Hotel as
an Eligible Hotel, the Borrower may so notify the Administrative Agent in
accordance with the provisions of Section 7.23(b), which provisions shall apply
as the Administrative Agent may determine in its sole discretion.

         within 135 days of the Trigger Date; or

                  (p)      Any default shall occur under the provisions of
         Section 8.17; or

                  (q)      Any "Event of Default" (as defined in any other
         Loan Document) shall occur.

                  9.2. Remedies. (a) If there shall occur and be continuing any
Event of Default, the Administrative Agent (i) shall at the request, or may with
the consent, of the Requisite Lenders by notice to the Borrower, declare the
obligation of each Lender to make Loans and of the Issuing Bank to issue
Facility Letters of Credit to be terminated, whereupon the same shall forthwith
terminate, and (ii) shall at the request, or may with the consent, of the
Requisite Lenders by notice to the Borrower, declare the Loans, all interest
thereon and all other amounts and Obligations payable under this Agreement to be
forthwith due and payable, whereupon the Notes, all such interest and all such
amounts and Obligations shall become and be forthwith due and payable, without
presentment, demand, protest or further notice of any kind, all of which are
hereby expressly waived by the Borrower; provided, however, that upon the
occurrence of the Event of Default specified in Section 9.1(e) above, (A) the
obligation of each Lender to make Loans and of the Issuing Bank to issue
Facility Letters of Credit shall automatically be terminated and (B) the Loans,
all such interest and all such amounts and Obligations shall automatically
become and be due and

                                       103

payable, without presentment, demand, protest or any notice of any kind, all of
which are hereby expressly waived by the Borrower. In addition to the remedies
set forth above, the Administrative Agent may exercise any remedies under any of
the Loan Documents or otherwise provided by applicable law.

                  (b) If the Administrative Agent exercises any rights or
remedies pursuant to Section 9.2(a), the Administrative Agent shall not, without
the consent of the Requisite Lenders, rescind the exercise of said rights or
remedies.


                                    ARTICLE X

                            THE ADMINISTRATIVE AGENT

                  In performing its functions and duties under this Agreement,
the Administrative Agent shall act solely as agent for the Lenders and does not
assume and shall not be deemed to have assumed any obligation or relationship of
agency, trustee or fiduciary with or for the Borrower. The provisions of this
Article X are solely for the benefit of the Administrative Agent and the
Lenders, and the Borrower shall have no obligations to the Administrative Agent
or the Lenders under this Article X, nor shall the Borrower have any right to
rely on or enforce any of the provisions of this Article X. The provisions of
this Article X may be amended without the consent or approval of the Borrower.
In the event any right or obligation of the Borrower under the terms of this
Article X conflicts with the rights and obligations of the Borrower under the
terms of any other Article of this Agreement, the rights and obligations of the
Borrower under such other Article shall govern.


                  10.1. Authorization and Action. (a) Each Lender hereby
appoints and authorizes the Administrative Agent to take such action as agent
(including, if applicable, collateral agent) on its behalf and to exercise such
powers under this Agreement and the other Loan Documents as are delegated to the
Administrative Agent by the terms hereof and thereof, together with such powers
as are reasonably incidental thereto. Without limitation of the foregoing, each
Lender hereby authorizes the Administrative Agent to execute and deliver, and to
perform its obligations under, each of the Loan Documents to which the
Administrative Agent is a party, and to exercise all rights, powers and remedies
that the Administrative Agent may have under such Loan Documents.

                  (b) Without limiting the generality of the foregoing, the
Administrative Agent shall have the sole and exclusive right and authority (i)
to act as the disbursing and collecting agent for the Lenders with respect to
all payments and collections

                                       104

<PAGE>   112



arising in connection with this Agreement and the other Loan Documents or with
respect to any collateral or security hereafter given with respect to the
Obligations ("Collateral"), (ii) to execute and deliver each Security Document
relating to the Collateral and accept delivery of each such Security Document
delivered by the Borrower or any Eligible Hotel Owner, (iii) to act as
collateral agent for the Lenders for purposes of the perfection of all Liens
created by the Security Documents and all other purposes stated therein; (iv) to
manage, supervise and otherwise deal with the Collateral; (v) to take such
action as is necessary or desirable to maintain the perfection and priority of
the Liens created or purported to be created by the Security Documents; and (vi)
except as may be otherwise specifically restricted by the terms of this
Agreement or any other Loan Document, to exercise all remedies given to the
Administrative Agent or the Lenders with respect to the Collateral under the
Loan Documents relating thereto, applicable law or otherwise.

                  (c) The Administrative Agent is hereby authorized on behalf of
all Lenders, without the necessity of any notice to or further consent from any
Lender, from time to time prior to an Event of Default, to take any action with
respect to any Collateral or Loan Document which may be necessary to perfect and
maintain perfected the Administrative Agent's Liens upon Collateral granted
pursuant to the Loan Documents. The Administrative Agent may make, and shall be
reimbursed by the Lenders (in accordance with their Ratable Portions), to the
extent not reimbursed by the Borrower, for, Protective Advance(s) during any one
calendar year with respect to each Eligible Hotel up to the sum of (i) amounts
expended to pay real estate taxes, assessments and governmental charges or
levies imposed upon such Eligible Hotel, (ii) amounts expended to pay insurance
premiums for policies of insurance related to such Eligible Hotel, and (iii) One
Hundred Thousand Dollars ($100,000). Protective Advances in excess of said sum
during any calendar year for any Eligible Hotel shall require the consent of the
Requisite Lenders.

                  (d) Each Lender hereby authorizes the Administrative Agent to
execute and deliver the release of any Lien held by the Administrative Agent for
the benefit of the Lenders against:

                  (i)      any Eligible Hotel, upon any Disposition thereof in
                           accordance with the provisions of Section 8.16; and

                  (ii)     all of the Collateral, upon final and indefeasible
                           payment in full of the Obligations and termination of
                           this Agreement.

                  (e) As to any matters not expressly provided for by this
Agreement and the other Loan Documents (including, without limitation,
enforcement or collection of the Notes), the Administrative Agent shall not be
required to exercise any discretion or take any action, but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Requisite Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes;
provided, however, that the Administrative Agent shall not be required to take
any action which the Administrative Agent in good faith believes exposes it to
personal liability or is contrary to this Agreement or applicable law. The
Administrative Agent agrees to give to each Lender prompt notice of (i) each
notice and (ii) to the extent the Administrative Agent grants any consents,
approvals, disapprovals or waivers to the Borrower pursuant to the directions of
the Requisite Lenders or all of the Lenders as required hereunder, notice of
such consent, approval, disapproval or waiver, given to it by, or by it to, any
Loan Party pursuant to the terms of this Agreement or the other Loan Documents.

                  10.2. Administrative Agent's Reliance, Etc. Neither the
Administrative Agent, nor any of its Affiliates or any of the respective
directors, officers, agents or employees of the Administrative Agent or any such
Affiliate shall be liable for any action taken or omitted to be taken by it,
him, her or them under or in connection with this Agreement or the other Loan
Documents, except for its, his, her or their own gross negligence or wilful
misconduct. Without limitation of the generality of the foregoing, the
Administrative Agent (i) may treat the payee of any Note as the holder thereof
until such note has been assigned in accordance with Section 11.7; (ii) may rely
on the Register to the extent set forth in Section 11.7(c); (iii) may consult
with legal counsel (including, without limitation, counsel to the Borrower or
any other Loan Party), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts; (iv) makes no warranty or representation to any Lender and shall not be
responsible to any Lender for any statements, warranties or representations made
in or in connection with this Agreement or any of the other Loan Documents; (v)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement or any
of the other Loan Documents on the part of the Borrower or any other Loan Party
or to inspect the property (including, without limitation, the books and
records) of the Borrower or any other Loan Party; (vi) shall not be responsible
to any Lender for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any of the other Loan

                                       106

<PAGE>   114



Documents or any other instrument or document furnished pursuant hereto or
thereto; and (vii) shall incur no liability under or in respect of this
Agreement or any of the other Loan Documents by acting upon any notice, consent,
certificate or other instrument or writing (which may be by telegram, cable,
telex or facsimile transmission) believed by it to be genuine and signed or sent
by the proper party or parties.

                  10.3. Bank One and Affiliates. With respect to its Commitment,
the Loans made by it and each Note issued to it, Bank One shall have the same
rights and powers under this Agreement as any other Lender and may exercise the
same as though it were not the Administrative Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Bank One in its
individual capacity. Bank One and its Affiliates may accept deposits from, lend
money to, act as trustee under indentures of, and generally engage in any kind
of business with, the Borrower or any other Loan Party or any of their
respective Subsidiaries and any Person who may do business with or own
securities of the Borrower or any other Loan Party or any of their respective
Subsidiaries, all as if Bank One were not the Administrative Agent and without
any duty to account therefor to the Lenders.

                  10.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Administrative Agent or any
other Lender and based on the financial statements referred to in Article V and
such other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement and other
Loan Documents.

                  10.5. Decisions Following Event of Default; Enforcement. After
the occurrence of an Event of Default, the following agreements among the
Lenders shall apply and shall control over any contrary agreements among the
Lenders provided in any other Article of this Agreement:

                  (a) The Administrative Agent shall, in consultation with the
Co-Agents, determine in its sole discretion whether and in what manner and to
what extent any and all rights and remedies under the Loan Documents, at law or
in equity shall be exercised in respect of an Event of Default and shall be
authorized to take any actions in connection therewith and shall keep the
Lenders reasonably informed as to such actions, provided, however, that the
Administrative Agent shall not without the consent of the

                                       107

<PAGE>   115



Requisite Lenders, and will, upon direction from the Requisite Lenders, take any

                           any legal notice required to exercise any power of

                           by law to realize on the Collateral or any portion
                           thereof; (C) the filing of any complaint for

                           undertaking, if any, given by a Guarantor or an
                           indemnitor in connection with the Loan Documents or

                           written demand that the Collateral or any material
                           portion thereof be conveyed and/or delivered to the
                           Lenders in lieu of foreclosure thereon, or the
                           acceptance by the Administrative Agent of any

                           the joining in any filing, of a petition for
                           involuntary bankruptcy of the Borrower, any Guarantor
                           or any Eligible Hotel Owner, under the Bankruptcy
                           Code or any similar proceeding under federal or state
                           law; or (H) the commencement of any adversary
                           proceeding (within the meaning of the Bankruptcy
                           Code) in any bankruptcy case commenced by or against
                           the Borrower, any Guarantor or any Eligible Hotel

                           otherwise as

                           determined by the records of the Administrative
                           Agent);

                  (iii)    accept a conveyance and assignment of all or
                           substantially all of the Borrower's or any Eligible

                           Collateral in lieu of foreclosure;

                  (iv)     in consideration of a conveyance and assignment of
                           the nature described in (iii) immediately above,
                           discontinue any and all Enforcement Actions and
                           release from, or otherwise agree not to pursue, the
                           Borrower, any Guarantor or any Eligible Hotel Owner
                           with respect to, all or any part of their respective
                           obligations under any of the Loan Documents; and/or

                  (v)      engage in any other modification of the Obligations
                           or Loan Documents or any other judicial or
                           non-judicial arrangement relating to the Loan
                           Documents which is the substantial equivalent of any
                           one or more of the foregoing actions.

                  (c) In the event that the Administrative Agent or its Designee
shall be appointed as a receiver or a mortgagee in possession of any Collateral
as a result of any action taken pursuant to this Section 10.5, any decisions,
actions or inactions by the Administrative Agent with respect to the management,
leasing, operation, or administration of such Collateral shall be subject to the
provisions of Section 10.6.

                  10.6. Acquisition of Collateral. (a) In the event that, as a
result of any Event of Default and the pursuit of any Enforcement Action, any of
the Collateral is acquired or to be acquired on behalf of the Lenders, the
provisions of this Section 10.6 shall govern the manner in which the Lenders
shall acquire, own, operate, manage, administer, lease, and dispose of such
Collateral.

                  (b) The Administrative Agent may, in its sole discretion,
elect to hold title to the Collateral in an Affiliate of the Administrative
Agent (the "Designee") which shall at all times following such acquisition be
the designee of the Administrative Agent for the benefit of the Lenders with
respect to the ownership, operation, management, administration, leasing, and
disposition of the Collateral.

                  (c) As soon as reasonably practicable after the Requisite
Lenders have approved the acquisition of any Collateral pursuant to Section
10.5, the Administrative Agent shall, in

                                       109

<PAGE>   117



consultation with the Co-Agents, prepare a "Post-Foreclosure Plan" which shall,
among other things, contain (i) provisions by which operating budgets and
capital improvement budgets are developed by the Administrative Agent and
approved by the Requisite Lenders, (ii) provisions by which a Hotel management
company or companies will be selected for the Collateral, subject to the
approval of the Requisite Lenders and (iii) provisions for establishing and
revising from time to time, upon approval of the Requisite Lenders, a plan for
the marketing and disposition of the Collateral. Upon approval of the
Post-Foreclosure Plan by the Requisite Lenders, the Administrative Agent shall
be authorized to take (or elect not to take) any and all actions which the
Administrative Agent would take (or not take) if it were the sole owner of the
Collateral (provided, such actions are consistent with the Post-Foreclosure
Plan), using the same diligence and care as customarily used by the
Administrative Agent and/or its affiliates with respect to similar property held
for its own account, subject only to the limitations, consents, approvals, and
directions expressly provided for in the Post- Foreclosure Plan. Except as
otherwise provided in a Post- Foreclosure Plan approved by the Requisite
Lenders, the Administrative Agent shall not sell or otherwise dispose of any
Collateral acquired by it or make any purchase money loan in connection with any
sale of such Collateral, except with the prior approval of the Requisite
Lenders.

                  (d) From time to time, but not less frequently than quarterly,
the Administrative Agent shall (to the extent funds are available for such
purpose) make distributions out of Gross Revenues to the Lenders, after payment
of the following, in the following order of priority:

                  (i)      all actual, out-of-pocket costs and expenses,
                           including attorneys' and paralegals' fees and
                           expenses, filing fees, court costs, title charges,
                           appraisal fees, environmental evaluation costs, and
                           other inspection fees, in each case payable to third
                           parties, incurred by the Administrative Agent on
                           behalf of the Lenders in connection with any actual
                           or contemplated Enforcement Action, or on account of
                           any actual or potential default by any Loan Party
                           under any of the Loan Documents or in connection with
                           any of the Collateral, to the extent not previously
                           reimbursed by the Borrower or otherwise;

                  (ii)     any Protective Advances made by the Administrative
                           Agent;

                  (iii)    amounts previously advanced by one or more Lenders on
                           account of any default by any other Lender in

                                       110

<PAGE>   118



                           making any payment or contributions of funds required
                           under this Agreement, the Loan Documents or any
                           agreement hereafter entered into among the Lenders
                           with respect to the Collateral;

                  (iv)     fees payable to the Administrative Agent; and

                  (v)      amounts of any reserves to be maintained in
                           accordance with the Post-Foreclosure Plan.

In no event shall the Administrative Agent be required to make any distributions
prior to approval of a Post-Foreclosure Plan by the Requisite Lenders; provided,
that any funds which would otherwise be available for distribution shall be
maintained in a separate, interest-bearing account for the benefit of the
Lenders and shall be distributed promptly upon such approval of a Post-
Foreclosure Plan. In addition, promptly after the closing of any sale or
disposition of any Collateral, the Administrative Agent shall distribute any net
proceeds to the Lenders after payment in full of all amounts described above, to
the extent remaining unpaid through the time of such closing. If any sale shall
involve any purchase money financing, any purchase money deed of trust or
mortgage taken in connection with the disposition of the Collateral shall name
the Administrative Agent, as the agent for the Lenders, as the beneficiary or
mortgagee. In such case, the Administrative Agent and the Lenders shall be bound
by the provisions of this Agreement with respect to such purchase money deed of
trust or mortgage defining the rights of the Administrative Agent and the
Lenders in the same Ratable Portions as provided herein, insofar as this
Agreement is appropriate or applicable, and upon request of the Administrative
Agent, the Lenders shall execute and deliver to the Administrative Agent such
agreements as the Administrative Agent reasonably may require to confirm or
conform this Agreement to the terms and circumstances applicable to such
purchase money financings.

                  (e) No Lender shall be entitled to sell, assign, convey,
pledge, hypothecate, encumber, or otherwise transfer all or any portion of its
ownership interest in the Collateral, except as provided in Section 11.7.

                  (f) The Administrative Agent, in such capacity, shall have no
duty or obligation to advance any of its own funds to pay any expense or
discharge any obligation of the Lenders or attendant to the Collateral, and the
Administrative Agent's duties to discharge its responsibilities under this
Section 10.6 shall be limited by the availability of funds received from the
Collateral or the Lenders. In the event (i) the Administrative Agent shall at
any time have insufficient funds from the Collateral to pay any expense or
obligation in connection with the Collateral, or (ii) the necessary funds are
not provided by

                                       111

<PAGE>   119



the Lenders after a request therefor by the Administrative Agent, then the
Administrative Agent shall take such actions as it deems appropriate to protect
and preserve the Collateral to the extent available funds allow, but the
Administrative Agent shall not be responsible for any loss or damage to the
Collateral or the Lenders, as a result of such unavailability of funds or the
Administrative Agent's inability to act as a result thereof.

                  10.7. Indemnification. The Lenders agree to indemnify the
Administrative Agent and its Affiliates, and their respective directors,
officers, employees, agents and advisors (to the extent not reimbursed by the
Borrower or other Loan Parties), ratably according to the respective principal
amounts of the Notes then held by each of them (or if no Notes are at the time
outstanding, ratably according to the respective amounts of the aggregate of
their Commitments, determined at the time indemnification is sought hereunder),
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses and disbursements
(including, without limitation, fees and disbursements of legal counsel) of any
kind or nature whatsoever which may be imposed on, incurred by, or asserted
against, the Administrative Agent in any way relating to or arising out of this
Agreement or the other Loan Documents or any action taken or omitted by the
Admini strative Agent under this Agreement or the other Loan Documents;
provided, however, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Administrative Agent's or
such Affiliate's gross negligence or wilful misconduct. Without limitation of
the foregoing, each Lender agrees to reimburse the Administrative Agent promptly
upon demand for its ratable share of any out-of-pocket expenses (including,
without limitation, fees and disbursements of legal counsel) incurred by the
Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
its rights or responsibilities under, this Agreement or the other Loan Documents
(including without limitation amounts incurred under Section 10.6), to the
extent that the Administrative Agent is not reimbursed for such expenses by the
Borrower or another Loan Party.

                  10.8. Successor Agent. The Administrative Agent may resign at
any time by giving written notice thereof to the Lenders and the Borrower and
may be removed by the Requisite Lenders either (a) for good cause or (b) at any
time that the aggregate amount of the Commitments held by the Administrative
Agent and its Affiliates is less than $20,000,000. Furthermore, in the event
that at any time the Administrative Agent assigns its entire interest as a
Lender hereunder to an Eligible Assignee

                                       112

<PAGE>   120



as permitted by Section 11.7 hereof, which Eligible Assignee is not an Affiliate
of the Administrative Agent, then the Administrative Agent shall resign as
Administrative Agent. Upon any such resignation or removal (which shall be
effective upon such date as a successor Agent accepts its appointment), the
Requisite Lenders shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Requisite Lenders, and shall
have accepted such appointment, within 30 days after the retiring Administrative
Agent's giving of notice of resignation or the Requisite Lenders' removal of the
retiring Administrative Agent, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Agent, which shall be a commercial
bank organized under the laws of the United States of America or of any State
thereof, having a combined capital and surplus of at least $50,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations under this Agreement and the other Loan
Documents. After any retiring Administrative Agent's resignation or removal
hereunder as Administrative Agent, the provisions of this Article X shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement and the other Loan Documents.

herein to take such action, affect the rights or duties of the Administrative
Agent under this Agreement or the other Loan Documents; and provided, further,
that no amendment, waiver or consent shall, unless in writing and signed by the

Lenders requesting the Lenders' determination, consent, approval or disapproval
(i) shall be given in the form of a written notice to each Lender, (ii) shall be

determination, approval, consent or disapproval is requested, or shall advise
each Lender where such matter or thing may be inspected, or shall otherwise

requested by a

                                       114

shall include the Administrative Agent's recommended course of action or
determination in respect thereof. Each Lender shall reply promptly, but in any
event within ten (10) Business Days of receipt by such Lender of a request for
consent, approval, disapproval or waiver, from the Administrative Agent (the
"Lender Reply Period"). Unless a Lender shall give written notice to the
Administrative Agent that it objects to consenting, approving, disapproving or
waiving any matter as requested by the Administrative Agent within the Lender
Reply Period, such Lender shall be deemed to have consented, approved,
disapproved or waived such matters as specified in the Administrative Agent's
request.

                  11.2. Notices, Etc. All notices and other com munications

answerback, telecopied with confirmation of receipt, delivered to the cable

that notices and communications to the Administrative Agent pursuant to Article

                  11.3. No Waiver; Remedies. No failure on the part of any
Lender or the Administrative Agent or the Issuing Bank to exercise, and no delay
in exercising, any right hereunder or under any Note shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right preclude any
other

                                       115

<PAGE>   123



or further exercise thereof or the exercise of any other right. The remedies
herein provided are cumulative and not exclusive of any remedies provided by
law.

                  11.4. Costs; Expenses; Indemnities. (a) The Borrower agrees to
pay on demand (i) all costs and expenses of the Administrative Agent, the
Lenders, the Issuing Bank and their respective Affiliates in connection with the
preparation, execution, delivery, administration, syndication, modification and
amendment of this Agreement, each of the other Loan Documents (including, if
applicable, Security Documents) and each of the other documents (including
documents delivered pursuant to Section 3.4 or Section 7.23) to be delivered
hereunder and thereunder, including, without limitation, the fees and
out-of-pocket expenses of counsel, accountants, appraisers, consultants or
industry experts retained by the Administrative Agent or any of the Lenders with
respect thereto and with respect to advising as to their rights and
responsibilities under this Agreement and the other Loan Documents, (ii) all
costs and expenses of the Administrative Agent, the Issuing Bank or any of the
Lenders (including, without limitation, the fees and out-of-pocket expenses of
counsel, accountants, appraisers, consultants or industry experts retained by
the Administrative Agent, the Issuing Bank or any Lender) in connection with the
restructuring or enforcement (whether through negotiation, legal proceedings or
otherwise) of this Agreement and the other Loan Documents and (iii) with respect
to each Limited Guaranty (if any) hereafter executed and delivered to the
Administrative Agent and accepted by the Lenders, an administrative fee (for the
account of the Lenders) in the amount of $5,000.00. In the event of any court
proceedings, court costs and attorneys' fees shall be set by the court and not
by jury and shall be included in any judgment obtained by the Administrative
Agent, the Issuing Bank or any Lender. Notwithstanding the foregoing, the
Borrower's liability to pay the fees and out-of-pocket expenses of counsel to
the Lenders in connection with the preparation, execution and delivery of the
Loan Documents shall be limited to payment of a sum not to exceed $42,500.00,
but such limitation shall not apply to any Loan Documents prepared, executed or
delivered after the Closing Date or to the fees and expenses of Quarles & Brady.

                  (b) The Borrower agrees to indemnify and hold harmless the
Administrative Agent, the Issuing Bank and each Lender and their respective
Affiliates, and the directors, officers, employ ees, agents, attorneys,
consultants and advisors of or to any of the foregoing (including, without
limitation, those retained in connection with the satisfaction or attempted
satisfaction of any of the conditions set forth in Article III) (each of the
foregoing being an "Indemnitee") from and against any and all claims, damages,
liabilities, obligations, losses, penalties, actions, judgments, suits, costs,
disbursements and expenses of

                                       116

<PAGE>   124



any kind or nature (including, without limitation, fees and disbursements of
counsel to any such Indemnitee and experts, engineers and consultants and the
costs of investigation and feasibility studies) which may be imposed on,
incurred by or asserted against any such Indemnitee in connection with or
arising out of any investigation, litigation or proceeding, whether or not any
such indemnitee is a party thereto, whether direct, indirect, or consequential
and whether based on any federal, state or local law or other statutory
regulation, securities or commercial law or regulation, or under common law or
in equity, or in contract, tort or otherwise, in any manner relating to or
arising out of or based upon or attributable to this Agreement, any other Loan
Document, any document delivered hereunder or thereunder, any Obligation, or any
act, event or transaction related or attendant to any thereof, including,
without limitation, (i) arising from any misrepresentation or breach of warranty
under Section 5.18 or any Environmental Claim or any Environmental Lien or any
Remedial Action arising out of or based upon anything relating to real property
owned or leased by the Borrower or any of its Subsidiaries (collectively, the
"Indemnified Matters"); provided, however, that the Borrower shall not have any
obligation under this Section 11.4(b) to an Indemnitee with respect to any
Indemnified Matter caused by or resulting from the gross negligence or willful
misconduct of that Indemnitee, as determined by a court of competent
jurisdiction in a final non-appealable judgment or order.

                  (c) If any Lender receives any payment of principal of, or is
subject to a conversion of, any Eurodollar Rate Loan other than on the last day
of an Interest Period relating to such Loan, as a result of any payment or
conversion made by the Borrower or acceleration of the maturity of the Notes
pursuant to Section 9.2 or for any other reason, the Borrower shall, upon demand
by such Lender (with a copy of such demand to the Administrative Agent), to the
extent not previously paid to such Lender pursuant to any other provision
hereof, pay to the Administrative Agent for the account of such Lender all
amounts required to compensate such Lender for any additional losses, costs or
expenses which it may reasonably incur as a result of such payment or
conversion, including, without limitation, any loss (including, without
limitation, loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Lender to fund or maintain such Loan.

                  (d) The Borrower shall indemnify the Administrative Agent, the
Issuing Bank and the Lenders for, and hold the Administrative Agent and the
Lenders harmless from and against, any and all claims for brokerage commissions,
fees and other compensation made against the Administrative Agent, the Issuing
Bank and the Lenders for any broker, finder or consultant with

                                       117

<PAGE>   125



respect to any agreement, arrangement or understanding made by or on behalf of
any Loan Party or any of its Subsidiaries in connection with the transactions
contemplated by this Agreement.

                  (e) The Borrower agrees that any indemnification or other
protection provided to any Indemnitee pursuant to this Agreement (including,
without limitation, pursuant to this Section 11.4) or any other Loan Document
shall (i) survive payment of the Obligations and (ii) inure to the benefit of
any Person who was at any time an Indemnitee under this Agreement or any other
Loan Document.

                  11.5. Right of Set-off. Upon the occurrence and during the
continuance of any Event of Default, each Lender and the Issuing Bank is hereby
authorized by the Borrower at any time and from time to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender or the Issuing Bank to or for the
credit or the account of the Borrower against any and all of the Obligations now
or hereafter existing whether or not such Lender or the Issuing Bank shall have
made any demand under this Agreement or any Note or any other Loan Document and
although such Obligations may be unmatured, provided, however, that the Lenders
and the Issuing Bank agree (for their sole benefit and not with the Borrower)
that, at any time that the Obligations are secured, no such right of set off
(including, without limitation, any rights under Section 2.14(b)) shall be
exercised without the consent of all Lenders and the Issuing Bank. Each Lender
and the Issuing Bank agree promptly to notify the Borrower after any such
set-off and application made by such Lender; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender and the Issuing Bank under this Section
are in addition to the other rights and remedies (including, without limitation,
other rights of set-off) which such Lender and the Issuing Bank may have.

                  11.6. Binding Effect. This Agreement shall become effective
when it shall have been executed by the Borrower and the Administrative Agent
and when the Administrative Agent shall have been notified by each Lender that
such Lender has executed it and thereafter shall be binding upon and inure to
the benefit of the Borrower, the Administrative Agent, the Issuing Bank and each
Lender and their respective successors and assigns, except that the Borrower
shall not have the right to assign its rights hereunder or any interest herein
without the prior written consent of the Lenders.

                  11.7. Assignments and Participations. (a) Subject to
the provisions of Section 11.7(i), each Lender may sell,

                                       118

<PAGE>   126



transfer, negotiate or assign to one or more other Lenders or Eligible Assignees
all or a portion of its Commitments, the Loans owing to it and the Notes held by
it and a commensurate portion of its rights and obligations hereunder and under
the other Loan Documents; provided, however, that (i) the aggregate amount of
the Commitment and Loans being assigned pursuant to each such assignment shall
in no event be less than $10,000,000, (ii) the Administrative Agent shall have
approved such assignment, which approval shall not be unreasonably withheld,
(iii) only at such times as (A) the aggregate amount of the Commitments held by
Bank One, Credit Lyonnais, Wells Fargo and their respective Affiliates is less
than $67,000,000 and (B) no Default or Event of Default has occurred that is
continuing, the Borrower shall have approved such assignment, which approval
shall not be unreasonably withheld, and (iv) each assignee hereunder shall also
be an Eligible Assignee; and provided further that any Lender may assign any
interest in the Commitment and the Loans to an Affiliate of the assigning Lender
without approval by the Administrative Agent or the Borrower. The parties to
each assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording, an Assignment and Acceptance, together with the Notes
(or an Affidavit of Loss and Indemnity with respect to such Notes satisfactory
to the Administrative Agent) subject to such assignment. Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in such Assignment and Acceptance, (A) the assignee thereunder shall become a
party hereto and, to the extent that rights and obligations under the Loan
Documents have been assigned to such assignee pursuant to such Assignment and
Acceptance, have the rights and obligations of a Lender hereunder and
thereunder, and (B) the assignor thereunder shall, to the extent that rights and
obligations under this Agreement have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights (except those which survive the
payment in full of the Obligations) and be released from its obligations under
the Loan Documents (and, in the case of an Assignment and Acceptance covering
all or the remaining portion of an assigning Lender's rights and obligations
under the Loan Documents, such Lender shall cease to be a party hereto).

                  (b) By executing and delivering an Assignment and Acceptance,
the Lender assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any of
the statements, warranties or representations made in or in connection with this
Agreement or any other Loan Document furnished pursuant thereto or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or any other Loan Document or any other instrument

                                       119

<PAGE>   127
or document furnished pursuant hereto or thereto; (ii) such assigning Lender
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of any Loan Party or the performance or observance by
any Loan Party of any of its obligations under this Agreement or any other Loan
Document or of any other instrument or document furnished pursu ant hereto or
thereto; (iii) such assigning Lender confirms that it has delivered to the
assignee and the assignee confirms that it has received a copy of this Agreement
and each of the Loan Documents together with a copy of the most recent financial
statements delivered by the Borrower to the Lenders pursuant to each of the
clauses of Section 7.11 (or if no such statements have been delivered, the
financial statements referred to in Section 5.5 of this Agreement) and such
other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into such Assignment and Acceptance; (iv)
such assignee will, independently and without reliance upon the Administrative
Agent, such assigning Lender or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agree ment; (v)
such assignee confirms that it is an Eligible Assignee; (vi) such assignee
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement and the other Loan
Documents as are delegated to the Administrative Agent by the terms hereof and
thereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all of the obligations which by the terms of this Agreement are required to be
performed by it as a Lender.

                  (c) The Administrative Agent shall maintain at its address
referred to in Section 11.2 a copy of each Assignment and Acceptance delivered
to and accepted by it and a register for the recordation of the names and
addresses of the Lenders and the Commitments of and principal amount of the
Loans owing to each Lender from time to time (the "Register"). The entries in
the Register shall be conclusive and binding for all purposes, absent manifest
error, and the Loan Parties, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register as a Lender for all purposes
of this Agreement. The Register shall be available for inspection by the
Borrower, the Administrative Agent or any Lender at any reasonable time and from
time to time upon reasonable prior notice. The Administrative Agent shall supply
to the Borrower promptly after any amendment thereto, a copy of the amended
Register.

                  (d) Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an assignee representing that
it is an Eligible Assignee, together with the Notes subject to

                                       120

<PAGE>   128



such assignment, the Administrative Agent shall, if such Assignment and
Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register and (iii) give prompt
notice thereof to the Borrower. Within five Business Days after its receipt of
such notice, the Borrower, at its own expense, shall execute and deliver to the
Administrative Agent, in exchange for such surrendered Notes, new Notes to the
order of such Eligible Assignee in an amount equal to the Commitments assumed by
it pursuant to such Assignment and Acceptance and, if the assigning Lender has
retained Commitments hereunder, new Notes to the order of the assigning Lender
in an amount equal to the Commitments retained by it hereunder. Such new Notes
shall be dated the same date as the surrendered Notes and be in substantially
the form of Exhibit E hereto.

                  (e) In addition to the other assignment rights provided in
this Section 11.7, each Lender may assign, as collateral or otherwise, any of
its rights under this Agreement (including, without limitation, rights to
payments of principal or interest on the Loans) to any Federal Reserve Bank
without notice to or consent of the Borrower or the Administrative Agent;
provided, however, that no such assignment shall release the assigning Lender
from any of its obligations hereunder. The terms and conditions of any such
assignment and the documentation evidencing such assignment shall be in form and
substance satisfactory to the assigning Lender and the assignee Federal Reserve
Bank.

                  (f) Each Lender may sell participations to one or more banks
or other Persons in or to all or a portion of its rights and obligations under
the Loan Documents (including, without limitation, all or a portion of its
Commitment, the Loans owing to it and the Note held by it). The terms of such
participation shall not, in any event, require the participant's consent to any
amendments, waivers or other modifications of any provision of any Loan
Documents, the consent to any departure by any Loan Party therefrom, or to the
exercising or refraining from exercising any powers or rights which such Lender
may have under or in respect of the Loan Documents (including, without
limitation, the right to enforce the obligations of the Loan Parties), except if
any such amendment, waiver or other modification or consent would reduce the
amount, or postpone any date fixed for, any amount (whether of principal,
interest or fees) payable to such participant under the Loan Documents, to which
such participant would otherwise be entitled under such participation. In the
event of the sale of any participation by any Lender, (i) such Lender's
obligations under the Loan Documents (including, without limitation, its
Commitment) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of

                                       121

<PAGE>   129



such obligations, (iii) such Lender shall remain the holder of such Note and
Obligations for all purposes of this Agreement, and (iv) the Borrower, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement.

                  (g) Each participant shall be entitled to the benefits of
Sections 2.11, 2.13 and 2.15 as if it were a Lender; provided, however, that
anything herein to the contrary notwithstanding, the Borrower shall not, at any
time, be obligated to pay to any assignee or participant of any interest of any
Lender, under Section 2.11, 2.13 or 2.15, any sum in excess of the sum which if
the Borrower would not at the time of such assignment have been obligated to pay
to such assignor Lender any such amount in respect of such interest had such
assignment not been effected or had such participation not been sold.

                  (h) An assignment of all or any portion of its Commitment,
Loans or Note by a Lender which is the Issuing Bank shall not constitute an
assignment of any of its rights or obligations as the Issuing Bank.

                  (i) Each of Bank One, Credit Lyonnais and Wells Fargo agrees
that, prior to the first anniversary of the Closing Date, it (the "Selling
Lender") shall not sell, assign, transfer or grant a participation interest in
(any of the foregoing being hereinafter referred to as a "Sale Transaction") all
or any portion of the Selling Lender's interest in its Commitment, Loans or Note
(the interest to be sold in a Sale Transaction being herein referred to as the
"Sale Interest") to any Person (the "Purchaser") unless each of such other two
Lenders (the "Non- selling Lenders") is also given the right (but without any
obligation to do so) to participate in such Sale Transaction and to sell to such
Purchaser a portion of the Non-selling Lender's interest in its Commitment,
Loans and Note, equal to one-third (1/3) of the Sale Interest, for consideration
equal to one-third (1/3) of the consideration to be paid by such Purchaser to
the Selling Lender, and otherwise on all of the terms, provisions and conditions
of the Sale Transaction between the Selling Lender and such Purchaser. Prior to
any Sale Transaction, the Selling Lender shall give each of the Non-selling
Lenders not less than seven (7) days' prior written notice (the "Sale Notice")
of such Sale Transaction, including a description of the Sale Interest, the
consideration to be paid therefor and all of the other terms and conditions
thereof. If a Non-selling Lender, within seven (7) days of its receipt of the
Sale Notice, gives to the Selling Lender written notice that the Non-selling
Lender elects to participate in such Sale Transaction, then, provided such Sale
Transaction is consummated within thirty (30) days of the Sale Notice, the
Non-selling Lender shall, at the same time at which

                                       122

<PAGE>   130
the Selling Lender consummates its Sale Transaction with the Purchaser, likewise
consummate a Sale Transaction with the Purchaser on the same terms and
conditions, and the Sale Interest to be sold by the Selling Lender shall be
reduced by the one-third (1/3) interest sold by the Non-selling Lender, such
that the total interest in the Commitments, Loans and Notes being acquired by
such Purchaser equals but does not exceed the Sale Interest. If a Non-selling
Lender does not, within such seven (7) day period, give notice of its election
to participate in the Sale Transaction, the Selling Lender may proceed to sell
the Sale Interest as set forth in its Sale Notice (except to the extent that the
other Non-selling Lender may have exercised its right to participate in the Sale
Transaction). The failure of a Non- selling Lender to elect to participate in
the Sale Transaction shall not give the other Non-selling Lender the right to
sell an additional one-third (1/3) interest, and each Non-selling Lender's right
shall be limited to a sale of an interest equal to one-third (1/3) of the total
Sale Interest. If the Sale Transaction with the Purchaser is not consummated
within thirty (30) days of the Sale Notice, the Sale Transaction may not be
consummated unless the Selling Lender gives the Non-selling Lenders another Sale
Notice as provided above.

                  11.8. Governing Law; Severability. This Agreement and the
Notes and the rights and obligations of the parties hereto and thereto shall be
governed by, and construed and interpreted in accordance with, the law of the
State of Arizona. Wherever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this agreement shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement.

                  11.9. Submission to Jurisdiction; Service of Process. (a) Any
legal action or proceeding with respect to this Agreement or the Notes or any
document related thereto may be brought in, Arizona State or United States
District Court sitting in Phoenix, Arizona, and, by execution and delivery of
this Agreement, the Borrower hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts. The parties hereto hereby irrevocably waive any objection, including,
without limitation, any objection to the laying of venue or based on the grounds
of forum non conveniens, which any of them may now or hereafter have to the
bringing of any such action or proceeding in such respective jurisdictions.

                  (b) The Borrower irrevocably consents to the service
of process of any of the aforesaid courts in any such action or

                                      123

<PAGE>   131



proceeding by the mailing of copies thereof by registered or certified mail,
postage prepaid, to the Borrower at its address provided herein.

                  (c) Nothing contained in this Section 11.9 shall affect the
right of the Administrative Agent, the Issuing Bank, any Lender or any holder of
a Note to serve process in any other manner permitted by law or commence legal
proceedings or otherwise proceed against the Borrower in any other jurisdiction.

                  11.10. Section Titles. The Section titles contained in this
Agreement are and shall be without substantive meaning or content of any kind
whatsoever and are not a part of the agreement between the parties hereto.

                  11.11. Execution in Counterpart. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

                  11.12. Entire Agreement. This Agreement, together with all of
the other Loan Documents and all certificates and documents delivered hereunder
or thereunder, and the agreements referred to in Section 2.4(b) embody the
entire agreement of the parties and supersedes all prior agreements and
understandings relating to the subject matter hereof.

                  11.13. Confidentiality. Each of the Lenders and the
Administrative Agent agrees to keep information obtained by it pursuant hereto
and the other Loan Documents confidential and agrees that it will only use such
information in connection with the transactions contemplated by this Agreement
and not disclose any of such information other than (i) to such Lender's or the
Administrative Agent's, as the case may be, employees, representatives and
agents who are or are expected to be involved in the evaluation of such
information in connection with the transactions contemplated by this Agreement
and who are advised of the confidential nature of such information, (ii) to the
extent such information presently is or hereafter becomes available to such
Lender or the Administrative Agent, as the case may be, on a non-confidential
basis from a source other than the Borrower, (iii) to the extent disclosure is
required by law, regulation or judicial order or requested or required by bank
regulators or auditors, or (iv) to assignees or participants or potential
assignees or participants who agree to be bound by the provisions of this
sentence.

                  11.14. WAIVER OF RIGHTS TO TRIAL BY JURY.  EACH PARTY
TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY
JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING

                                       124

<PAGE>   132



UNDER THE LOAN DOCUMENTS, INCLUDING, WITHOUT LIMITATION, ANY PRESENT OR FUTURE
MODIFICATION THEREOF OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL
TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THE LOAN
DOCUMENTS (AS NOW OR HEREAFTER MODIFIED) OR ANY OTHER INSTRUMENT, DOCUMENT OR
AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS
RELATED HERETO OR THERETO, IN EACH CASE WHETHER SUCH CLAIM, DEMAND, ACTION OR
CAUSE OF ACTION IS NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN
CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT
ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO
TO THE WAIVER OF ANY RIGHT THEY MIGHT OTHERWISE HAVE TO TRIAL BY JURY.

                  11.15. Binding Arbitration. (a) All controversies and claims
of any nature arising directly or indirectly out of this Agreement or any other
Loan Documents, including, without limitation, the Guaranties, shall at the
written request of any party be arbitrated pursuant to the applicable rules of
the American Arbitration Association. The arbitration proceeding shall be
conducted in the State of Arizona. Judgment upon any award rendered by the
arbitrator(s) may be entered in any court having jurisdiction. Notwithstanding
any choice of law provision in this Agreement or in any other Loan Document, the
Federal Arbitration Act shall apply to the construction and interpretation of
this arbitration provision.

                  (b) A single arbitrator shall have the power to render an
award not to exceed $100,000. When any party files a claim in excess of this
amount, the arbitration decision shall be made by the majority vote of three
arbitrators. No arbitrator shall have the power to restrain any act of any
party.

                  (c) No provision of this Section 11.15 shall limit the right
of any party to exercise self-help remedies, to foreclose against any
Collateral, or to obtain any provisional or ancillary remedies (including but
not limited to injunctive relief or the appointment of a receiver) from a court
of competent jurisdiction. Without limitation of the foregoing, the
Administrative Agent may enforce its rights under a Deed of Trust by exercise of
the power of sale, judicial foreclosure or otherwise as permitted under
applicable law. The institution and maintenance of any such remedy shall not
constitute a waiver of the right to submit any controversy or claim to
arbitration. The statute of limitations, estoppel, waiver, laches, and similar
doctrines which would otherwise be applicable in an action brought by a party
shall be applicable in any arbitration proceeding.

                           ASSIGNMENT AND ACCEPTANCE




                                                   ___________________ ___, 19__



                 Reference is made to the Revolving Credit Agreement, dated as
of May 1, 1997, among Sunstone Hotel Investors, L.P., a Delaware limited
partnership (the "Borrower"), the financial institutions party thereto and Bank
One, Arizona, NA, as Administrative Agent for the financial institutions party
thereto (said Agreement, as it may be amended or otherwise modified from time
to time, being the "Credit Agreement", and capitalized terms not defined herein
but defined therein being used herein as therein defined).

______________________________ (the "Assignor") and
______________________________ (the "Assignee") agree as follows:

                 1.  The Assignor hereby sells and assigns to the Assignee, and
the Assignee hereby purchases and assumes from the Assignor, that interest in
and to all of the Assignor's rights and obligations under the Credit Agreement
as of the date hereof which represents the percentage interest specified on
Schedule I of all outstanding rights and obligations under the Credit Agreement
(including, without limitation, such interest in each of the Assignor's
outstanding Commitments, if any, the Obligations owing to it and the Notes held
by it).  After giving effect to such sale and assignment, the Assignee's
Commitments (and the Commitments retained by the Assignor, if any) and the
amount of the Loans owing to the Assignee (and the Assignor, if any) will be as
set forth in Section 2 of Schedule I and will otherwise comply with the
requirements of Section 11.7(a).

                 2.  The Assignor (i) represents and warrants that it is the
legal and beneficial owner of the interest being assigned by it hereunder and
that such interest is free and clear of any adverse claim; (ii) makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with the
Credit Agreement or any other Loan Document or any other instrument or document
furnished pursuant thereto or the execution, legality, validity,
enforceability, genuineness,





                                      A-1
<PAGE>   138

sufficiency or value of the Credit Agreement or any other Loan Document or any
other instrument or document furnished pursuant thereto; (iii) makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of any Loan Party or the performance or observance by any
Loan Party of any of its obligations under the Credit Agreement or any other
Loan Document or any other instrument or document furnished pursuant thereto;
and (iv) attaches the Notes referred to above and requests that the
Administrative Agent exchange such Notes for new Notes as follows:  [specify
date of Notes, amounts, Assignee].

                 3.  The Assignee (i) confirms that it has received a copy of
the Credit Agreement, together with copies of the financial statements referred
to in Section 5.5 thereof and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
this Assignment and Acceptance; (ii) agrees that it will, independently and
without reliance upon the Administrative Agent, the Assignor or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under the Credit Agreement; (iii) appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers under the Credit Agreement as are delegated to the Administrative
Agent by the terms thereof, together with such powers as are reasonably
incidental thereto; (iv) agrees that it will perform in accordance with their
terms all of the obligations which by the terms of the Credit Agreement are
required to be performed by it as a Lender; (v) represents and warrants that it
is an Eligible Assignee; and (vi) specifies as its Domestic Lending Office (and
address for notices) and Eurodollar Lending Office the offices set forth
beneath its name on the signature pages hereof[; and* (vii) attaches the forms
prescribed by the Internal Revenue Service of the United States certifying as
to the Assignee's status for purposes of determining exemption from United
States withholding taxes with respect to all payments to be made to the
Assignee under the Credit Agreement and the Notes or such other documents as
are necessary to indicate that all such payments are subject to such rates at a
rate reduced by an applicable tax treaty].

                 4.  Following the execution of this Assignment and Acceptance
by the Assignor and the Assignee, it will be delivered

to the Administrative Agent, together with an assignment processing fee in the
sum of $2,500 payable to and for the benefit of the Administrative Agent, for
acceptance and recording by the Administrative Agent.  The effective date of
this Assignment and Acceptance shall be the date of acceptance thereof by the
Administrative Agent and, provided no Default or Event of Default exists, the
Borrower, unless otherwise specified on Schedule I hereto (the "Effective
Date").

                 5.  Upon such acceptance by the Administrative Agent and, if
applicable, the Borrower and recording by the Administrative Agent, as of the

to the extent provided in this Assignment and Acceptance, have the rights and
obligations under the Credit Agreement of a Lender thereunder and (ii) the
Assignor shall, to the extent provided in this Assignment and Acceptance,
relinquish its rights and be released from its obligations under the Credit

use and occupancy of all or any part of the Trust Property, whether written or

guarantees of the lessee's obligations thereunder and together with all
extensions, modifications and renewals thereof (hereinafter called the

Property or any part thereof, including without limitation room rents, minimum

Assignment, and not in lieu hereof, Beneficiary may require a separate
assignment of rents and leases and/or separate specific assignments of rents
and leases covering one or more of the Leases; the terms of all such
assignments are incorporated herein by reference.

         3.2     Trustor hereby authorizes and directs the lessees and tenants
under the Leases that, upon written notice from Beneficiary, all Rents shall be
paid directly to Beneficiary as they become due.  Trustor hereby relieves the
lessees and tenants from any liability to Trustor by reason of the payment of
the Rents to Beneficiary.  Nevertheless, Trustor shall be entitled to collect
the Rents until Beneficiary notifies the lessees and tenants in writing to pay
the Rents to Beneficiary.  Beneficiary is hereby authorized to give such
notification upon the occurrence of an Event of Default and at any time
thereafter while such Event of Default is continuing.  Receipt and application
of the Rents by Beneficiary shall not constitute a waiver of any right of
Beneficiary under this Deed of Trust or applicable law, shall not cure any
Event of Default hereunder, and shall not invalidate or affect any act done in
connection with such Event of Default, including, without limitation, any
trustee's sale or foreclosure proceeding.

         3.3     All Rents collected by Trustor shall be applied in the
following manner:

                 First, to the payment of all taxes and lien assessments levied
against the Trust Property, where provision for paying such is not otherwise
made;

                 Second, to the payment of ground rents (if any) payable with
respect to the Trust Property;

                 Third, to the payment of any amounts due and owing under the
Obligation;

                 Fourth, to the payment of current operating costs and expenses
(including repairs, maintenance and necessary acquisitions of property and
expenditures for capital improvements) arising in connection with the Trust
Property;

                 Fifth, to Trustor or its designee.





                                      -4-
<PAGE>   149
All Rents collected by Beneficiary may be applied to the items above listed in
any manner that Beneficiary deems advisable and without regard to the
aforestated priorities.

         3.4     Trustor represents and warrants that:  (i) the Leases are in
full force and effect and have not been modified or amended; (ii) the Rents
have not been waived, discounted, compromised, setoff or paid more than one
month in advance; (iii) there are no other assignments, transfers, pledges or
encumbrances of any Leases or Rents; and (iv) to the best of Trustor's
knowledge neither Trustor nor the lessees and tenants are in default under the
Leases.

         3.5     Trustor shall (i) fulfill or perform each and every term,
covenant and provision of the Leases to be fulfilled or performed by the lessor
thereunder; (ii) give prompt notice to Beneficiary of any notice received by
Trustor of default thereunder or of any alleged default or failure of
performance that could become a default thereunder, together with a complete
copy of any such notice; and (iii) enforce, short of termination thereof, the
performance or observance of each and every term, covenant and provision of
each Lease to be performed or observed by the lessees and tenants thereunder.

         3.6     Trustor, without the prior written consent of Beneficiary,
shall not:  (i) cancel, modify or alter, or accept the surrender of, any Lease;
(ii) assign, transfer, pledge or encumber, the whole or any part of the Leases
and Rents to anyone other than Beneficiary; (iii) accept any Rents more than
one month in advance of the accrual thereof; (iv) do or permit anything to be
done, the doing of which, or omit or refrain from doing anything, the omission
of which, could be a breach or default under the terms of any Lease or a basis
for termination thereof; or (v) enter in to any new tenant leases.

         3.7     Neither Beneficiary nor the Lenders assumes and shall not be
liable for any obligation of the lessor under any of the Leases and all such
obligations shall continue to rest upon Trustor as though this assignment had
not been made.  Neither Beneficiary nor the Lenders shall be liable for the
failure or inability to collect any Rents.

         3.8     Neither the Assignment of Rents and Leases contained herein or
in any separate assignment nor the exercise by Beneficiary of any of its rights
or remedies thereunder or in connection therewith, prior to Beneficiary
obtaining actual possession of the Trust Property as provided in Paragraph 8.2
hereof, shall constitute Beneficiary (or the Lenders) a "mortgagee in
possession" or otherwise make Beneficiary or the Lenders responsible or liable
in any manner with respect to the Trust Property or the occupancy, operation or
use thereof.  In the event Beneficiary obtains actual possession of the Trust
Property as provided in Paragraph 8.2 hereof, Beneficiary shall have the
rights, and Beneficiary's liability shall be limited, as provided in that
Paragraph.

<PAGE>   152
together with all products and proceeds of all of the foregoing, in any form,
including all proceeds received, due or to become due from any sale, exchange
or other disposition thereof, whether such proceeds are cash or non-cash in
nature, and whether represented by checks, drafts, notes or other instruments
for the payment of money.  The personal property described or referred to in
this Paragraph 4.1 is hereinafter called the "Personal Property."  The security
interests granted in this Paragraph 4.1 are hereinafter severally and
collectively called the "Security Interest."

         4.2     The Security Interest shall be self-operative with respect to
the Personal Property, but Trustor shall execute and deliver on demand such
additional security agreements, financing statements and other instruments as
may be requested in order to impose the Security Interest more specifically
upon the Personal Property.  The Security Interest, at all times, shall be
prior to any other interests in the Personal Property except any lien or
security interest granted in connection with any Permitted Exception.  Trustor
shall act and perform as necessary and shall execute and file all security
agreements, financing statements, continuation statements and other documents
requested by Beneficiary to establish, maintain and continue the perfected
Security Interest.  Trustor, on demand, shall promptly pay all costs and
expenses of filing and recording, including the costs of any searches, deemed
necessary by Beneficiary from time to time to establish and determine the
validity and the continuing priority of the Security Interest.

         4.3     Trustor shall not sell, transfer, assign or otherwise dispose
of any Personal Property or any interest therein without obtaining the prior
written consent of Beneficiary, except Personal Property that Trustor is
obliged to replace pursuant to the terms hereof.  Unless Beneficiary then
agrees otherwise in writing, all proceeds from any permitted sale or
disposition in excess of that required for replacements shall be paid to
Beneficiary to be applied to the Obligation, whether or not then due.  Trustor
shall keep the Personal Property free of all security interests or other
encumbrances, except the Security Interest and any security interests and
encumbrances granted in connection with any Permitted Exception.  Although
proceeds of Personal Property are covered hereby, this shall not be construed
to mean that Beneficiary consents to any sale of the Personal Property.

         4.4     Trustor shall keep and maintain the Personal Property in good
condition and repair, and shall promptly replace any part thereof that from
time to time may become obsolete, badly worn or in a state of disrepair.  All
such replacements shall be free of any other security interest or encumbrance,
except any security interest or encumbrance granted in connection with any
Permitted Exception.

         4.5     Except for purposes of replacement and repair, Trustor,
without the prior written consent of Beneficiary, shall not remove, or permit
the removal of, any Personal Property from the Premises.

         4.6     Trustor hereby warrants, covenants and agrees that:  (i) the
Personal Property is or will be used primarily for business (other than farm)
purposes; (ii) the Personal Property will be





                                      -8-
<PAGE>   153

kept at the Premises; and (iii) Trustor's records concerning the Personal
Property will be kept at Trustor's address as set forth in the beginning of
this Deed of Trust.

         4.7     Trustor represents and warrants that (i) the name specified
above for Trustor is the true and correct legal name of Trustor, and (ii) the
address specified above is the address of Trustor's chief executive office (or
residence if Trustor is an individual without an office).  Trustor shall give
Beneficiary immediate written notice of any change in the location of:  (i)
Trustor's chief executive office (or residence if Trustor is an individual
without an office), as set forth in the beginning of this Deed of Trust; (ii)
the Personal Property or any part thereof; or (iii) Trustor's records
concerning the Personal Property.  Trustor shall give Beneficiary immediate
written notice of any change in the name, identity or structure of Trustor.

         4.8     All covenants and warranties of Trustor contained in this Deed
of Trust shall apply to the Personal Property whether or not expressly referred
to in this Section 4.  The covenants and warranties of Trustor contained in
this Section 4 are in addition to, and not in limitation of, those contained in
the other provisions of this Deed of Trust.

         4.9     Upon its recording in the real property records, this Deed of
Trust shall be effective as a financing statement filed as a fixture filing.
In addition, a carbon, photographic or other reproduced copy of this Deed of
Trust and/or any financing statement relating hereto shall be sufficient for
filing and/or recording as a financing statement.  The filing of any other
financing statement relating to any personal property, rights or interests
described herein shall not be construed to diminish any right or priority
hereunder.

SECTION 5. PROTECTION AND PRESERVATION OF THE TRUST PROPERTY

         5.1     Trustor shall neither commit nor permit to occur any waste
upon the Trust Property but shall at all times make or cause to be made all
repairs, maintenance, renewals and replacements as may be necessary to maintain
the Trust Property in good condition and repair.  Trustor shall keep the Trust
Property free of termites, dry rot, fungus, beetles and all other harmful or
destructive insects and shall keep all plants, trees and shrubs included in the
Trust Property neatly pruned and in good condition.  Trustor shall keep the
Trust Property free of rubbish and other unsightly or unhealthful conditions.
Trustor shall neither use nor permit the use of the Trust Property in violation
of any applicable statute, ordinance or regulation, including without
limitation, the Americans With Disabilities Act of 1990 and corresponding rules
and regulations (the "ADA"), or any policy of insurance insuring the Trust
Property.

         5.2     Trustor shall promptly complete any improvements that may be
commenced, in good and workmanlike manner and in conformity with the ADA and
with plans and specifications approved by Beneficiary.  Trustor shall repair
and restore, in conformity with the ADA, any portions of the Trust Property
that may be damaged or destroyed.  Trustor shall pay when due all claims for
work performed and materials furnished on or in connection with the Trust
Property or any part thereof and shall pay, discharge, or cause to be removed,
all mechanic's, artisan's,





                                      -9-
<PAGE>   154
laborer's or materialman's charges, liens, claims of liens or encumbrances upon
the Trust Property.  Trustor shall comply with all laws, ordinances and
regulations now or hereafter enacted, including, without limitation, the ADA,
affecting the Trust Property or requiring any alterations or improvements to be
made.  Except as required by law, Trustor shall not remove, substantially
alter, or demolish any building or improvement included in the Trust Property
without Beneficiary's prior written consent.

         5.3     (a)      Trustor shall provide and maintain policies of
insurance on the Trust Property in accordance with the Loan Agreement.

                 (b)      In the event of loss, Trustor shall give immediate
notice to Beneficiary, and Beneficiary may make proof of loss if not made
promptly by Trustor.  Each insurance company is hereby authorized and directed
to make payment for loss directly to Beneficiary, instead of to Trustor or to
Trustor and Beneficiary jointly; Beneficiary may apply all or any part of such
insurance proceeds to the payment of the Obligation, whether or not then due,
or the restoration or repair of the Trust Property.  Beneficiary shall not be
responsible for any insurance, for the collection of any insurance proceeds, or
for the insolvency of any insurer.  Application of insurance proceeds by
Beneficiary shall not cure nor waive any Event of Default nor invalidate any
act done hereunder because of any such Event of Default.  In the event of the
sale of the Trust Property under the power of sale herein granted to Trustee,
or upon foreclosure of this Deed of Trust as a mortgage, or in the event
Beneficiary or a receiver appointed by the court shall take possession of the
Trust Property without sale, then all right, title and interest of Trustor in
and to all insurance policies then in force shall inure to the benefit of and
pass to the beneficiary in possession, receiver or purchaser at such sale, as
the case may be.  Beneficiary is hereby appointed attorney in fact for Trustor
to assign and transfer such policies.

                 (c)      If the insurance proceeds are to be used for the
restoration and repair of the Trust Property, they shall be held by Beneficiary
in a non-interest bearing account selected by Beneficiary in its sole and
absolute discretion (the "Restoration Account").  Trustor, at its expense,
shall promptly prepare and submit to Beneficiary all plans and specifications
necessary for the restoration and repair of the damaged Trust Property,
together with evidence acceptable to Beneficiary setting forth the total
expenditure needed for the restoration and repair based upon a fixed price
contract with a reputable builder and covered by performance and labor and
material payment bonds.  The plans and specifications and all other aspects of
the proposed restoration and repair shall be subject to Beneficiary's approval.
In the event the insurance proceeds held in the Restoration Account are
insufficient to complete the restoration and repair, Trustor shall deposit in
the Restoration Account an amount equal to the difference between the amount
then held in the Restoration Account and the total contract price for the
restoration and repair.  Trustor may commence restoration and repair of the
damaged Trust Property only when authorized in writing by Beneficiary to do so
and thereafter shall proceed diligently with the restoration and repair until
completed.  Disbursements shall be made from the Restoration Account for the
restoration and repair in accordance with a disbursement schedule, and subject
to other terms and conditions, acceptable to Beneficiary.  Disbursements from
the Restoration Account shall be charged first





                                      -10-
<PAGE>   155

against funds deposited by Trustor and, after such funds are exhausted, against
the insurance proceeds deposited therein.  In the event the amounts held in the
Restoration Account exceed the cost of the restoration and repair of the
damaged Trust Property, the excess funds shall be disbursed to Trustor to the
extent of any amounts deposited therein by Trustor.  Any funds remaining after
such disbursement, at Beneficiary's option, may be applied by Beneficiary to
the payment of the Obligation, whether or not then due, or may be disbursed to
Trustor.  All funds held in the Restoration Account are hereby assigned to
Beneficiary as further security for the Obligation.  Beneficiary, at any time,
may apply all or any part of the funds held in the Restoration Account to the
curing of any Event of Default.

         5.4     Trustor shall pay or cause to be paid all taxes and
assessments of every kind, nature and description levied or assessed on or
against the Trust Property and shall deliver to Beneficiary, at least ten (10)
days before they become delinquent, receipts showing payment of all such taxes
and assessments and shall pay when due all dues and charges for water and water
delivery, electricity, gas, sewers, waste removal, bills for repairs, and any
and all other claims, encumbrances and expenses incident to the ownership of
the Trust Property.

         5.5     Trustor, or upon the occurrence of an Event of Default and the
continuation thereof, Beneficiary may contest, by appropriate legal
proceedings, the validity of any valuation for real or personal property tax
purposes or of any levy or assessment of any real or personal property taxes
against the Trust Property either in the name of Beneficiary or the name of
Trustor or both.  Trustor, upon notice and request by Beneficiary, shall join
in any such proceedings.  Trustor shall cooperate with Beneficiary in any such
proceeding and execute any documents or pleadings required for such purposes.
Trustor shall provide Beneficiary with a copy of the Notice of Valuation within
ten (10) days after receipt (five (5) days in the case of personal property).
Trustor shall reimburse Beneficiary for all costs and legal expenses incurred
by Beneficiary in connection with any such proceedings, but in no event shall
such reimbursement exceed the tax savings achieved for the period covered by
the Notice of Valuation.  To facilitate the right of Beneficiary to contest any
real or personal property tax valuation, levy, or assessment as described
above, Trustor does hereby make, constitute and appoint Beneficiary, and its
successors and assigns, Trustor's true and lawful attorney-in-fact, in
Trustor's name, place and stead, or otherwise, to file any claim or proceeding
or to take any action, either in its own name, in that of its nominee, in the
name of Trustor, or otherwise, to contest any real or personal property tax
valuation, levy, or assessment.  The power of attorney given herein is a power
coupled with an interest and shall be irrevocable so long as any part of the
Obligation remains unpaid or unperformed.  Beneficiary shall have no obligation
to exercise any of the foregoing rights and powers in any event.

         5.6     In order to insure the payment of taxes and assessments that
are now, or hereafter may be, a lien upon the Trust Property, and to insure the
payment of all premiums on policies of insurance required herein, Trustor, if
required by Beneficiary after the occurrence of any Event of Default and only
during the continuation thereof, shall pay to Beneficiary each month, in
addition to any other payments required hereunder, an amount equal to the taxes
and special assessments levied or to be levied against the Trust Property and
the premium or premiums that will become





                                      -11-
<PAGE>   156
due and payable to maintain the insurance on the Trust Property, all as
reasonably estimated by Beneficiary (giving due consideration to the previous
year's taxes, assessments and premiums) less all deposits therefore already
made, divided by the number of months remaining before one month prior to the
date when the taxes, assessments and premiums become delinquent.  If amounts
paid to Beneficiary under the term of this paragraph are insufficient to pay
all taxes, assessments and premiums as they become due, Trustor shall pay to
Beneficiary upon demand all additional sums necessary to fully pay and
discharge these items.  All moneys paid to Beneficiary under the terms of this
paragraph may be either held by Beneficiary to pay the taxes, assessments and
premiums before the same become delinquent or applied to the Obligation upon
payment by Beneficiary from its own funds of the taxes, assessments and
premiums.  To the extent provision is not made for payment pursuant to this
paragraph, Trustor shall remain obligated to pay all taxes, assessments and
premiums as they become due and payable.  Deposits made under this paragraph
may be commingled with Beneficiary's general funds; Beneficiary shall have no
liability to Trustor for interest on any deposits.

         5.7     Trustor hereby assigns, transfers and conveys to Beneficiary
all compensation and each and every award of damages in connection with any
condemnation for public or private use of, or injury to, the Trust Property or
any part thereof, to the extent of the Obligation then remaining unpaid, and
all such compensation and awards shall be paid directly to Beneficiary.
Beneficiary may apply all or any part of such compensation and awards to the
payment of the Obligation, whether or not then due, or to the restoration or
repair of the Trust Property.

SECTION 6. PROTECTION AND PRESERVATION OF BENEFICIARY'S INTEREST

         6.1     Trustor, by the payment of any such tax or taxes, shall
protect Beneficiary and the Lenders against any and all loss from any taxation
of indebtedness or deeds of trust, direct or indirect, that may be imposed upon
this Deed of Trust, the lien of this Deed of Trust on the Trust Property, or
upon the Obligation, by any law, rule, regulation or levy of the federal
government, any state government, or any political subdivision thereof.  In the
event the burden of such taxation cannot lawfully be shifted from Beneficiary
(or the Lenders, as the case may be) to Trustor, Beneficiary may declare the
entire Obligation due and payable sixty (60) days after notice to Trustor.

         6.2     If Trustor shall fail to pay any taxes, assessments, expenses
or charges, to keep all of the Trust Property free from liens and claims of
liens, to maintain and repair the Trust Property, or to procure and maintain
insurance thereon, or otherwise fail to perform as required herein, Beneficiary
and the Lenders may advance the monies necessary to pay the same, to accomplish
such maintenance and repairs, to procure and maintain such insurance or to so
perform; Beneficiary and the Lenders are hereby authorized to enter upon the
Trust Property for such purposes.

         6.3     Upon written request by Beneficiary, Trustor shall appear in
and prosecute or defend any action or proceeding that may affect the lien or
the priority of the lien of this Deed of





                                      -12-
<PAGE>   157

Trust or the rights of Beneficiary or the Lenders hereunder and shall pay all
costs, expenses (including the cost of searching title) and attorneys' fees
incurred in such action or proceeding.  Beneficiary and the Lenders may appear
in and defend any action or proceeding purporting to affect the lien or the
priority of the lien of this Deed of Trust or the rights of Beneficiary or the
Lenders.  Beneficiary may pay, purchase, contest or compromise any adverse
claim, encumbrance, charge or lien that in the judgment of Beneficiary appears
to be prior or superior to the lien of this Deed of Trust, other than any
Permitted Exceptions.

         6.4     Without obtaining the prior written consent of Trustor shall
not sell, transfer, convey, assign or otherwise dispose of, or further
encumber, all or any part of the Trust Property or any interest therein,
voluntarily or involuntarily, by operation of law or otherwise.  If Trustor is
a corporation, partnership, joint venture or trust, any material change in the
ownership or management of, or interest in, Trustor, or any pledge or
encumbrance of any interest in Trustor, shall be deemed to be a transfer of the
Trust Property.  Upon the occurrence of any such transaction with Beneficiary's
consent, or without Beneficiary's consent if the Lenders elect not to exercise
their rights and remedies for an Event of Default, the Lenders (i) may increase
the interest rate on all or any part of the Obligation to its then current
market rate for similar indebtedness; (ii) may charge a loan fee and a
processing fee in connection with the change; and (iii) shall not be obligated
to release Trustor from any liability hereunder or for the Obligation except to
the extent required by law.  Consent to any such transaction shall not be
deemed to be consent or a waiver of the requirement of consent to any other
such transaction.

         6.5     Without obtaining the prior written consent of Beneficiary,
Trustor shall not consent to, or vote in favor of, the inclusion of all or any
part of the Trust Property in any special district.  Trustor shall immediately
give notice to Beneficiary of any notification or advice that Trustor may
receive from any municipality or other third party of any intent or proposal to
include all or any part of the Trust Property in a special district.
Beneficiary shall have the right to file a written objection to the inclusion
of all or any part of the Trust Property in a special district, either in its
own name or in the name of Trustor, and to appear at, and participate in, any
hearing with respect to the formation of any such district.

         6.6     All rights, powers and remedies granted Beneficiary and the
Lenders herein, or otherwise available to Beneficiary and the Lenders, are for
the sole benefit and protection of Beneficiary and the Lenders, and Beneficiary
and the Lenders may exercise any such right, power or remedy at their option
and in their sole and absolute discretion without any obligation to do so.  In
addition, if, under the terms hereof, Beneficiary or the Lenders are given two
or more alternative courses of action, Beneficiary (or the Lenders, as the case
may be) may elect any alternative or combination of alternatives, at their
option and in their sole and absolute discretion.  All monies advanced by
Beneficiary or the Lenders under the terms hereof and all amounts paid,
suffered or incurred by Beneficiary or the Lenders in exercising any authority
granted herein, including reasonable attorneys' fees, shall be added to the
Obligation, shall be secured by this Deed of Trust, shall bear interest at the
highest rate payable on any of the Obligation until paid,





                                      -13-
<PAGE>   158
and shall be due and payable by Trustor to Beneficiary (or the Lenders, as the
case may be) immediately without demand.

         6.7     Trustor, upon request of Beneficiary, shall promptly correct
any defect, error or omission that may be discovered in the content of this
Deed of Trust or in the execution or acknowledgment hereof.  In addition,
Trustor shall do such further acts as may be necessary or that Beneficiary may
reasonably request to carry out more effectively the purposes of this Deed of
Trust, to subject any property intended to be encumbered hereby to the lien and
security interest hereof, and to perfect and maintain the lien and security
interest hereof.

no material adverse change in the financial condition or the results of the
operation of Trustor since the latest financial statement of Trustor given to
Beneficiary or the Lenders.

         7.4     Trustor has filed all federal, state and local tax returns and
has paid all of its current obligations before delinquent, including all
federal, state and local taxes and all other payments required under federal,

in violation of the ADA and is not subject to any existing, pending or
threatened investigation in connection with the ADA.

         7.6     All representations and warranties made herein shall survive

been fully paid and performed.

SECTION 8. DEFAULTS; REMEDIES

shall constitute an "Event of Default" under this Deed of Trust:

                 (a)      The abandonment by Trustor of all or any part of the
Trust Property.

                 (b)      The existence of any material encroachment upon the

                 (b)      Give such notice of default and of election to cause
the Trust Property to be sold as may be required by law or as may be necessary
to cause Trustee to exercise the power of sale granted herein.  Trustee shall
then record and give such notice of trustee's sale as then required by law and,
after the expiration of such time as may be required by law, may sell the Trust
Property at the time and place specified in the notice of sale, as a whole or
in separate parcels as directed by Beneficiary, or by Trustor to the extent
required by law, at public auction to the highest bidder for cash in lawful
money of the United States, payable at time of sale, all in accordance with
applicable law.  Trustee, from time to time, may postpone or continue the sale
of all or any portion of the Trust Property by public declaration at the time
and place last appointed for the sale.  No other notice of the postponed sale
shall be required.  Upon any sale, Trustee shall deliver its deed conveying the
property sold, without any covenant or warranty, express or implied, to the
purchaser or purchasers at the sale.  The recitals in such deed of any matters
or facts shall be conclusive as to the accuracy thereof.  Any person, including
Trustor, Trustee, Beneficiary or the Lenders, may purchase at the sale.

                 (c)      Commence proceedings for foreclosure of this Deed of
Trust in any other manner provided by law for the foreclosure of a real
property mortgage.

                 (d)      Exercise any or all of the remedies of a secured
party under the Uniform Commercial Code with respect to the Personal Property.
If Beneficiary should proceed to dispose of any of the Personal Property in
accordance with the provisions of the Uniform Commercial Code, five (5) days'
notice by Beneficiary to Trustor shall be deemed to be commercially reasonable
notice under any provision of the Uniform Commercial Code requiring notice.
Trustor, however, agrees that all property of every nature and description,
whether real or personal, covered by this Deed of Trust, together with all
personal property used on or in connection with the Premises or any business
conducted thereon by the Trustor and covered by separate security agreements,
is encumbered as one unit, that this Deed of Trust and such security interests,
at Beneficiary's option, may be foreclosed or sold in the same proceeding, and
that all property encumbered (both realty and personalty), at Beneficiary's
option, may be sold as such in one unit as a going business, subject to the
provisions of applicable law.

                 (e)      Without regard to the adequacy of any security for
the Obligation or the solvency of Trustor or any other person or entity, send
notifications to any and all lessees and tenants under the Leases that all
Rents shall be paid to Beneficiary.  Thereafter, Beneficiary shall be entitled
to collect the Rents until Trustor cures all Events of Default and may apply
the Rents collected at its sole discretion to the maintenance of the Trust
Property and/or the payment of the Obligation.

                 (f)      Apply any funds in the possession or control of
Beneficiary under the provisions of Paragraph 5.6 hereof to the payment of the
Obligation, in lieu of the purposes specified in that paragraph.

                 (g)      Apply for and obtain, without regard to the adequacy
of any security for the Obligation or the solvency of the Trustor or any other
person or entity, a receiver by any court of competent jurisdiction to take
charge of all the Trust Property, to manage, operate and carry on any business
then being conducted or that could be conducted on the Premises, to carry on,
protect, preserve, replace and repair the Trust Property, and receive and
collect all Rents and to apply the same to pay the receiver's expenses for the
operation of the Trust Property and then in the manner provided in Paragraph
3.3 herein.  Upon appointment of said receiver, Trustor shall immediately
deliver possession of all of the Trust Property to such receiver.  Neither the
appointment of a receiver for the Trust Property by any court at the request of
Beneficiary or by agreement with Trustor nor the entering into possession of
all or any part of the Trust Property by such receiver shall constitute
Beneficiary a "mortgagee in possession" or otherwise make Beneficiary
responsible or liable in any manner with respect to the Trust Property or the
occupancy, operation or use thereof.  Trustor agrees that Beneficiary shall
have the absolute and unconditional right to the appointment of a receiver in
any independent and/or separate action brought by Beneficiary regardless of
whether Beneficiary seeks any relief in such action other than the appointment
of a receiver.
                 (h)      Without regard to the adequacy of any security for
the Obligation or the solvency of Trustor or any other person or entity, enter
upon and take possession of all or any part of the Trust Property, either in
person or by agent or employee, or by a receiver appointed by





                                      -16-
<PAGE>   161
a court of competent jurisdiction; Trustor shall on demand peaceably surrender
possession of the Trust Property to Beneficiary.  Beneficiary, in its own name
or in the name of Trustor, may operate and maintain all or any part of the
Trust Property to such extent as Beneficiary deems advisable, may rent and
lease the same to such persons, for such periods of time, and on such terms and
conditions as Beneficiary in its sole discretion may determine, and may sue for
or otherwise collect any and all Rents, including those past due and unpaid.
Notwithstanding anything Beneficiary or the Lenders do, they will not be a
mortgagee or beneficiary in possession, and neither Beneficiary nor the Lenders
shall be subject to any liability, charge, or obligation therefor to Trustor,
other than for willful misconduct, and shall be entitled to operate any
business then being conducted or which could be conducted thereon or therewith
at the expense of and for the account of Trustor (and all net losses, costs and
expenses thereby incurred shall be advances governed by Paragraph 6.6 hereof),
to the same extent as the owner thereof could do, and to apply the Rents to pay
the receiver's expenses, if any, for the operation of the Trust Property and
then in the manner provided in Paragraph 3.3 herein.

         8.3     Trustor shall pay all costs and expenses, including without
limitation costs of title searches and title policy commitments, Uniform
Commercial Code searches, court costs, reasonable attorneys' fees, appraisals,
environmental studies and site assessments, incurred by Beneficiary and the
Lenders in enforcing payment and performance of the Obligation or in exercising
the rights and remedies of Beneficiary and the Lenders hereunder.  All such
costs and expenses shall be secured by this Deed of Trust and by all other lien
and security documents securing the Obligation.  In the event of any court
proceedings, court costs and attorneys' fees shall be set by the court and not
by jury and shall be included in any judgment obtained by Beneficiary or the
Lenders.

         8.4     In addition to any remedies provided herein for an Event of
Default, Beneficiary and the Lenders shall have all other legal or equitable
remedies allowed under applicable law (including specifically that of
foreclosure of this instrument as though it were a mortgage).  No failure on
the part of Beneficiary or the Lenders to exercise any of their rights
hereunder arising upon any Event of Default shall be construed to prejudice
their rights upon the occurrence of any other or subsequent Event of Default.
No delay on the part of Beneficiary or the Lenders in exercising any such
rights shall be construed to preclude them from the exercise thereof at any
time while that Event of Default is continuing.  Beneficiary may enforce any
one or more remedies or rights hereunder successively or concurrently.  By
accepting payment or performance of any of the Obligation after its due date,
neither Beneficiary nor the Lenders shall thereby waive the agreement contained
herein that time is of the essence, nor shall Beneficiary or the Lenders waive
either their right to require prompt payment or performance when due of the
remainder of the Obligation or their right to consider the failure to so pay or
perform an Event of Default.  In any action by Beneficiary or the Lenders to
recover a deficiency judgment for any balance due under the Notes upon the
foreclosure of this Deed of Trust or in any action to recover the Obligation or
Obligations secured hereby, and as a material inducement to making the loan
evidenced by the Notes, Trustor acknowledges and agrees that the successful bid
amount made at any judicial or non-judicial foreclosure sale, if any, shall be
conclusively deemed to constitute the fair market





                                      -17-
<PAGE>   162

value of the Premises, that such bid amount shall be binding against Trustor in
any proceeding seeking to determine or contest the fair market value of the
Premises and that such bid amount shall be the preferred alternative means of
determining and establishing the fair market value of the Premises.  Trustor
hereby waives and relinquishes any right to have the fair market value of the
Premises determined by a judge or jury in any action seeking a deficiency
judgment or any action on the Obligation or Obligations secured hereby,
including, without limitation, a hearing to determine fair market value
pursuant to A.R.S. '12-1566, '33-814, '33-725 or '33-727.

SECTION 9. GENERAL PROVISIONS

         9.1     Trustor shall defend, indemnify and hold harmless Beneficiary
and the Lenders, any successors to Beneficiary's and the Lenders' interest in
the Trust Property, any purchaser of the Trust Property upon foreclosure, and
all shareholders, directors, officers, employees and agents of all of the
foregoing and their heirs, personal representatives, successors and assigns
from and against all claims, costs, expenses, actions, suits, proceedings,
losses, damages and liabilities of any kind whatsoever, including but not
limited to all amounts paid in settlement of, and all costs and expenses
(including attorneys' fees) incurred in defending or settling, any actual or
threatened claim, action, suit or proceeding, directly or indirectly arising
out of or relating to the Obligation, this Deed of Trust, or the Trust
Property, including but not limited to (i) any violation of or claim of
violation of the ADA with respect to the Trust Property; or (ii) any breach of
any of the warranties, representations and covenants contained herein.  This
indemnity provision shall continue in full force and effect and shall survive
the payment and performance of the Obligation, the release of record of the
lien of this Deed of Trust, any foreclosure (or action in lieu of foreclosure)
of this Deed of Trust, the exercise by Beneficiary or the Lenders of any other
remedy under this Deed of Trust or any other document or instrument evidencing
or securing the Obligation, and any suit, proceeding or judgment against
Trustor by Beneficiary or the Lenders hereon.

         9.2     The acceptance of this Deed of Trust by Beneficiary and the
Lenders shall not be considered a waiver of or in any way to affect or impair
any other security that Beneficiary or the Lenders may have, acquire
simultaneously herewith, or hereafter acquire for the payment or performance of
the Obligation, nor shall the taking by Beneficiary or the Lenders at any time
of any such additional security be construed as a waiver of or in any way to
affect or impair the security of this Deed of Trust; Beneficiary and the
Lenders may resort, for the payment or performance of the Obligation, to their
several securities therefor in such order and manner as they may determine.

         9.3     Without notice or demand, without affecting the obligations of
Trustor hereunder or the personal liability of any person for payment or
performance of the Obligation, and without affecting the lien or the priority
of the lien of this Deed of Trust, Beneficiary, from time to time, may:  (i)
extend the time for payment of all or any part of the Obligation, accept a
renewal note therefor, reduce the payments thereon, release any person liable
for all or any part thereof, or otherwise change the terms of all or any part
of the Obligation; (ii) take and hold other security





                                      -18-
<PAGE>   163
for the payment or performance of the Obligation and enforce, exchange,
substitute, subordinate, waive or release any such security; (iii) consent to
the making of any map or plat of the Trust Property; (iv) join in granting any
easement on or in creating any covenants, conditions or restrictions affecting
the use or occupancy of the Trust Property; (v) join in any extension or
subordination agreement; or (vi) release or direct Trustee to release any part
of the Trust Property from this Deed of Trust.  Any such action by Beneficiary,
or Trustee at Beneficiary's direction, may be taken without the consent of any
junior lienholder and shall not affect the priority of this Deed of Trust over
any junior lien.

         9.4     Trustor waives and agrees not to assert:  (i) any right to
require Beneficiary and the Lenders to proceed against any guarantor, to
proceed against or exhaust any other security for the Obligation, to pursue any
other remedy available to Beneficiary and the Lenders, or to pursue any remedy
in any particular order or manner; (ii) the benefits of any legal or equitable
doctrine or principle of marshalling; (iii) the benefits of any statute of
limitations affecting the enforcement hereof; (iv) demand, diligence,
presentment for payment, protest and demand, and notice of extension, dishonor,
protest, demand and nonpayment, relating to the Obligation; and (v) any benefit
of, and any right to participate in, any other security now or hereafter held
by Beneficiary or the Lenders.

         9.5     Upon written request of Beneficiary and upon surrender of this
Deed of Trust and the Notes to Trustee for cancellation and retention or, if
requested, delivery, then Trustee (and Beneficiary if necessary to clear
title), upon payment of Trustee's fees, shall release, without warranty, the
Trust Property.  The recitals in such release of any matters or facts shall be
conclusive as to the accuracy thereof.  The grantee in such release may be
described as "the person or persons legally entitled thereto."  Five years
after issuance of such full release, Trustee may destroy the Notes and this
Deed of Trust (unless directed in such request to retain them), unless prior
thereto Trustee has been directed to deliver them to the person or persons to
whom the property was released.

         9.6     Beneficiary, the Lenders and Trustee shall have the right to
inspect the Trust Property at all reasonable times.

         9.7     Time is of the essence hereof.  All liability hereunder shall
be joint and several.  This Deed of Trust shall be binding upon, and shall
inure to the benefit of, the parties hereto and their heirs, personal
representatives, successors and assigns.  The provisions hereof shall apply to
the parties according to the context thereof and without regard to the number
or gender of words or expressions used.

         9.8     The acceptance by Trustee of this trust shall be evidenced
when this Deed of Trust, duly executed and acknowledged, is made a public
record as provided by law.  The trust created hereby is irrevocable by Trustor.

<PAGE>   164
         9.9     This Deed of Trust cannot be changed except by agreement, in
writing, signed by Trustor and Beneficiary.

         9.10    No setoff or claim that Trustor now has or may in the future
have against Beneficiary or the Lenders shall relieve Trustor from paying or
performing the Obligation.

         9.11    Each term, condition and provision of this Deed of Trust shall
be interpreted in such manner as to be effective and valid under applicable law
but if any term, condition or provision of this Deed of Trust shall be held to
be void or invalid, the same shall not affect the remainder hereof which shall
be effective as though the void or invalid term, condition or provision had not
been contained herein.  In addition, should this instrument be or become
ineffective as a deed of trust, then these presents shall be construed and
enforced as a realty mortgage with the Trustor being the Mortgagor and
Beneficiary being the Mortgagee.

         9.12    This Deed of Trust, the Obligation and the agreements of any
person or entity to pay or perform the Obligation shall be governed by and
construed according to the laws of the State of Arizona, except to the extent
that the state in which the Trust Property is located may require that its laws
be applied to the creation and priority of liens, to the perfection of security
interests and to any foreclosure, trustee's sale, appointment of receiver or
other remedy with respect to the Trust Property.  Any procedures provided
herein for such remedies shall be modified by and replaced with, where
inconsistent with or required by, any procedures or requirements of the laws of
the state in which the Trust Property is located.

         9.13    All notices required or permitted to be given hereunder shall
be in writing and may be given in person or by United States mail, by delivery
service or by electronic transmission.  Any notice directed to a party to this
Deed of Trust shall become effective upon the earliest of the following:  (i)
actual receipt by that party; (ii) delivery to the designated address of that
party, addressed to that party; or (iii) if given by certified or registered
United States mail, twenty-four (24) hours after deposit with the United States
Postal Service, postage prepaid, addressed to that party at its designated
address.  The designated address of a party shall be the address of that party
shown at the beginning of this Deed of Trust or such other address as that
party, from time to time, may specify by notice to the other parties.

                            FORMS OF LIMITED GUARANTY

                       UNCONDITIONAL GUARANTEE OF PAYMENT
                                (ROBERT A. ALTER)

TO:      BANK ONE, ARIZONA, NA
         CREDIT LYONNAIS NEW YORK BRANCH
         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1. FOR VALUAB1LE CONSIDERATION, the undersigned (hereinafter called
"Guarantor"), whose address is set forth after Guarantor's signature below,
unconditionally guarantees and promises to pay to the Lenders (under and as
defined in that certain Revolving Credit Agreement (as modified, amended or
restated from time to time, the "Loan Agreement"), dated of even date herewith,
by and among Bank One, Arizona, NA, Credit Lyonnais New York Branch and Wells
Fargo Bank, National Association (each a "Lender" and collectively, the
"Lenders") and Sunstone Hotel Investors, L.P., a Delaware limited partnership
(the "Borrower"); capitalized terms used herein but not defined herein shall
have the meaning provided for such terms in the Loan Agreement), or order, upon
demand, in lawful money of the United States, the full and prompt payment when
due, whether at maturity or earlier, by reason of acceleration or otherwise,
and at all times thereafter (i) the principal of and interest on the Loans and
(ii) all other Obligations arising under any Loan Document (all such guaranteed
amounts are hereinafter collectively called the "Indebtedness").

         2. (a) The obligations of Guarantor hereunder, are separate and
         independent of the obligations of Borrower and of any other guarantor
         (including, but not limited to, Charles L. Biederman), and a separate
         action or actions may be brought and prosecuted against Guarantor
         whether action is brought against Borrower or any other guarantor or
         whether Borrower or any other guarantor is joined in any action or
         actions. The obligations of Guarantor hereunder shall survive and
         continue in full force and effect until payment in full of the
         Indebtedness is actually received by the Lenders and the period of
         time has expired during which any payment made by Borrower, Guarantor
         or any other guarantor to the Lenders may be determined to be a
         Preferential Payment (defined below), notwithstanding any release or
         termination of Borrower's, Guarantor's or any other guarantor's
         liability by express or implied agreement with the Lenders or by
         operation of law and notwithstanding that the Indebtedness or any part
         thereof is deemed to have been paid or discharged by operation of law
         or by some act or agreement of the Lenders. For purposes of this
         Guarantee, the






<PAGE>   169

         Indebtedness shall be deemed to be paid only to the extent that the
         Lenders actually receive immediately available funds and to the extent
         of any credit bid by the Lenders at any foreclosure or trustee's sale
         of any security for the Indebtedness.

                  (b) Notwithstanding anything contained herein to the
         contrary, the recovery under this Guarantee with respect to the
         Indebtedness (which does not include any amounts recovered under
         Paragraph 11) shall be limited to the difference between (i) Eight
         Million Four Hundred Thousand and No/100 Dollars ($8,400,000) and (ii)
         any amounts that are unconditionally paid to and received by the
         Lenders under that certain Unconditional Guarantee of Payment, dated
         of even date herewith, executed by Charles L. Biederman in favor of
         the Lenders.

         3. Guarantor agrees that to the extent Borrower or Guarantor makes any
payment to the Administrative Agent or the Lenders in connection with the
Indebtedness, and all or any part of such payment is subsequently invalidated,
declared to be fraudulent or preferential , set aside or required to be repaid
by the Administrative Agent or the Lenders or paid over to a trustee, receiver
or any other entity, whether under any bankruptcy act or otherwise (any such
payment is hereinafter referred to as a "Preferential Payment"), then this
Guarantee shall continue to be effective or shall be reinstated, as the case
may be, and, to the extent of such payment or repayment by the Lenders (or the
Administrative Agent, as the case may be), the Indebtedness or part thereof
intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
made.

         4. Guarantor is providing this Guarantee at the instance and request
of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower. Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5. Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)
renew, modify, compromise, extend,





                                       -2-
<PAGE>   170
accelerate or otherwise change the time for payment of, or otherwise change the
terms of the Indebtedness or any part thereof, including increasing or
decreasing the rate of interest thereon; (b) release, substitute or add any one
or more endorsers or other guarantors; (c) take and hold security for the
payment of this Guarantee or the Indebtedness, and enforce, exchange,
substitute, subordinate, waive or release any such security; (d) proceed
against such security and direct the order or manner of sale of such security
as the Lenders in their discretion may determine; and (e) apply any and all
payments from Borrower, Guarantor or any other guarantor, or recoveries from
such security, in such order or manner as the Lenders in their discretion may
determine.


         6. Guarantor waives and agrees not to assert: (a) any right to require
the Lenders to proceed against Borrower or any other guarantor (including, but
not limited to, Charles L. Biederman), to proceed against or exhaust any
security for the Indebtedness, to pursue any other remedy available to the
Lenders, or to pursue any remedy in any particular order or manner; (b) the
benefit of any statute of limitations affecting Guarantor's liability hereunder
or the enforcement hereof; (c) demand, diligence, presentment for payment,
protest and demand, and notice of extension, dishonor, protest, demand,
nonpayment and acceptance of this Guarantee; (d) notice of the existence,
creation or incurring of new or additional indebtedness of Borrower to the
Lenders; (e) the benefits of any statutory provision limiting the liability of
a surety, including without limitation the provisions of A.R.S. Sections
12-1641, et seq. and Rule 17(f) of the Arizona Rules of Civil Procedure; (f)
any defense arising by reason of any disability or other defense of Borrower or
by reason of the cessation from any cause whatsoever (other than payment in
full) of the liability of Borrower for the Indebtedness; and (g) the benefits
of any statutory provision limiting the right of the Lenders to recover a
deficiency judgment, or to otherwise proceed against any person or entity
obligated for payment of the Indebtedness, after any foreclosure or trustee's
sale of any security for the Indebtedness, including without limitation the
benefits, if any, to Guarantor of A.R.S. Section 33-814 and Section 12-1566.
Guarantor hereby expressly consents to any impairment of collateral, including,
but not limited to, failure to perfect a security interest and release
collateral and any such impairment or release shall not affect Guarantor's
obligations hereunder. Until payment in full of the Indebtedness, Guarantor
shall have no right of subrogation and hereby waives any right to enforce any
remedy which the Lenders now have, or may hereafter have, against Borrower, and
waives any benefit of, and any right to participate in, any security held by





                                      -3-

the Lenders.

         7. All existing and future indebtedness of Borrower to Guarantor is
hereby subordinated to the Indebtedness and such indebtedness of Borrower to
Guarantor, if the Lenders so request, shall be collected, enforced and received
by Guarantor as trustee for the Lenders and shall be paid over to the Lenders
on account of the Indebtedness, but without reducing or affecting in any manner
the liability of Guarantor under the other provisions of this Guarantee.


         8. In addition to all liens upon, and rights of setoff against, the
monies, securities or other property of Guarantor given to the Lenders by law,
the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor. No lien or right of setoff shall be deemed to have
been waived by any act or conduct on the part of the Administrative Agent or
the Lenders, by any neglect to exercise such right of setoff or to enforce such
lien, or by any delay in so doing.

         9. It is not necessary for the Lenders to inquire into the powers of
Borrower or the officers, directors, partners or agents acting or purporting to
act on its behalf, and any of the Indebtedness made or created in reliance upon
the professed exercise of such powers shall be guaranteed hereunder.

         10. Within one hundred twenty (120) days after the close of each
fiscal year of Guarantor, while this Guarantee remains in effect, Guarantor
shall deliver to the Lenders financial statements of Guarantor, all in
reasonable detail satisfactory to the Lenders. Such financial statements shall
be certified by Guarantor. While this Guarantee remains in effect, Guarantor
shall deliver to the Lenders copies of Guarantor's federal income tax returns
within thirty (30) days of each filing of such returns. When requested by the
Administrative Agent, from time to time, Guarantor shall promptly deliver, in
writing, such further information as the Administrative Agent may reasonably
request relating to any such financial statements or returns.

         11. Guarantor agrees to pay all attorneys' fees and all other costs
and expenses which may be incurred by the





                                      -4-

Administrative Agent or the Lenders in enforcing this Guarantee or in
collecting all or any part of the Indebtedness.  In the event of any court
proceedings, court costs and attorneys' fees shall be set by the court and not
by the jury and shall be included in any judgment obtained by the
Administrative Agent or the Lenders.


         12. This Guarantee sets forth the entire agreement of Guarantor and
the Lenders with respect to the subject matter hereof and supersedes all prior
oral and written agreements and representations by the Lenders to Guarantor. No
modification or waiver of any provision of this Guarantee or any right of the
Lenders hereunder and no release of Guarantor from any obligation hereunder
shall be effective unless in a writing executed by an authorized officer of
each of the Lenders. There are no conditions, oral or otherwise, on the
effectiveness of this Guarantee.

         13.      This Guarantee shall inure to the benefit of the Lenders and
their successors and assigns and shall be binding upon Guarantor and its heirs,
personal representatives, successors and assigns.  The Lenders may assign this
Guarantee in whole or in part without notice.

         14. This Guarantee shall be governed by and construed according to the
laws of the State of Arizona except that the laws of the state of Guarantor's
domicile shall govern the power of Guarantor to bind the marital community and
the community assets of Guarantor and Guarantor's spouse, or if the state of
Guarantor's domicile is not a community property state, the power of Guarantor
to bind the property of Guarantor's spouse, for the payment and performance of
the obligations under this Guarantee. Guarantor represents and warrants that
the common domicile of Guarantor and Guarantor's spouse is in the State of
California.

         15.      Guarantor covenants and agrees to be bound by the arbitration
provisions contained in Section 11.15 of the Loan Agreement.

         16. Any legal action or proceeding with respect to this Guarantee or
any document related hereto may be brought in Arizona State or United States
District Court sitting in Phoenix, Arizona, and, by execution and delivery of
this Guarantee, Guarantor hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts. Guarantor hereby irrevocably waives any objection, including, without
limitation, any objection to the laying of venue or based on the grounds of
forum non conveniens,





                                      -5-

which Guarantor may now or hereafter have to the bringing of any such action or
proceeding in such respective jurisdictions. Guarantor irrevocably consents to
the service of process of any of the aforesaid courts in any such action or
proceeding by the mailing of copies thereof by registered or certified mail,

contained in this paragraph shall affect the right of the Administrative Agent,

permitted by law or commence legal proceedings or otherwise proceed against

                       UNCONDITIONAL GUARANTEE OF PAYMENT
                             (CHARLES L. BIEDERMAN)

TO:      BANK ONE, ARIZONA, NA
         CREDIT LYONN1AIS NEW YORK BRANCH
         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1. FOR VALUABLE CONSIDERATION, the undersigned (hereinafter called
"Guarantor"), whose address is set forth after Guarantor's signature below,
unconditionally guarantees and promises to pay to the Lenders (under and as
defined in that certain Revolving Credit Agreement (as modified, amended or
restated from time to time, the "Loan Agreement"), dated of even date herewith,
by and among Bank One, Arizona, NA, Credit Lyonnais New York Branch and Wells
Fargo Bank, National Association (each a "Lender" and collectively, the
"Lenders") and Sunstone Hotel Investors, L.P., a Delaware limited partnership
(the "Borrower"); capitalized terms used herein but not defined herein shall
have the meaning provided for such terms in the Loan Agreement), or order, upon
demand, in lawful money of the United States, the full and prompt payment when
due, whether at maturity or earlier, by reason of acceleration or otherwise,
and at all times thereafter (i) the principal of and interest on the Loans and
(ii) all other Obligations arising under any Loan Document (all such guaranteed
amounts are hereinafter collectively called the "Indebtedness").


         2. (a) The obligations of Guarantor hereunder, are separate and
         independent of the obligations of Borrower and of any other guarantor
         (including, but not limited to, Robert A. Alter), and a separate
         action or actions may be brought and prosecuted against Guarantor
         whether action is brought against Borrower or any other guarantor or
         whether Borrower or any other guarantor is joined in any action or
         actions. The obligations of Guarantor hereunder shall survive and
         continue in full force and effect until payment in full of the
         Indebtedness is actually received by the Lenders and the period of
         time has expired during which any payment made by Borrower, Guarantor
         or any other guarantor to the Lenders may be determined to be a
         Preferential Payment (defined below), notwithstanding any release or
         termination of Borrower's, Guarantor's or any other guarantor's
         liability by express or implied agreement with the Lenders or by
         operation of law and notwithstanding that the Indebtedness or any part
         thereof is deemed to have been paid or discharged by operation of law
         or by some act or agreement of the Lenders. For purposes of this
         Guarantee, the






<PAGE>   177

         Indebtedness shall be deemed to be paid only to the extent that the
         Lenders actually receive immediately available funds and to the extent
         of any credit bid by the Lenders at any foreclosure or trustee's sale
         of any security for the Indebtedness.

                  (b) Notwithstanding anything contained herein to the
         contrary, the recovery under this Guarantee with respect to the
         Indebtedness (which does not include any amounts recovered under
         Paragraph 11) shall be limited to the difference between (i) Eight
         Million Four Hundred Thousand and No/100 Dollars ($8,400,000) and (ii)
         any amounts that are unconditionally paid to and received by the
         Lenders under that certain Unconditional Guarantee of Payment, dated
         of even date herewith, executed by Robert A. Alter in favor of the
         Lenders.

         3. Guarantor agrees that to the extent Borrower or Guarantor makes any
payment to the Administrative Agent or the Lenders in connection with the
Indebtedness, and all or any part of such payment is subsequently invalidated,
declared to be fraudulent or preferential , set aside or required to be repaid
by the Administrative Agent or the Lenders or paid over to a trustee, receiver
or any other entity, whether under any bankruptcy act or otherwise (any such
payment is hereinafter referred to as a "Preferential Payment"), then this
Guarantee shall continue to be effective or shall be reinstated, as the case
may be, and, to the extent of such payment or repayment by the Lenders (or the
Administrative Agent, as the case may be), the Indebtedness or part thereof
intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
made.

         4. Guarantor is providing this Guarantee at the instance and request
of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower. Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5. Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)
renew, modify, compromise, extend,





                                      -2-
<PAGE>   178
accelerate or otherwise change the time for payment of, or otherwise change the
terms of the Indebtedness or any part thereof, including increasing or
decreasing the rate of interest thereon; (b) release, substitute or add any one
or more endorsers or other guarantors; (c) take and hold security for the
payment of this Guarantee or the Indebtedness, and enforce, exchange,
substitute, subordinate, waive or release any such security; (d) proceed
against such security and direct the order or manner of sale of such security
as the Lenders in their discretion may determine; and (e) apply any and all
payments from Borrower, Guarantor or any other guarantor, or recoveries from
such security, in such order or manner as the Lenders in their discretion may
determine.


         6. Guarantor waives and agrees not to assert: (a) any right to require
the Lenders to proceed against Borrower or any other guarantor (including, but
not limited to, Robert A. Alter), to proceed against or exhaust any security
for the Indebtedness, to pursue any other remedy available to the Lenders, or
to pursue any remedy in any particular order or manner; (b) the benefit of any
statute of limitations affecting Guarantor's liability hereunder or the
enforcement hereof; (c) demand, diligence, presentment for payment, protest and
demand, and notice of extension, dishonor, protest, demand, nonpayment and
acceptance of this Guarantee; (d) notice of the existence, creation or
incurring of new or additional indebtedness of Borrower to the Lenders; (e) the
benefits of any statutory provision limiting the liability of a surety,
including without limitation the provisions of A.R.S. Sections 12-1641, et seq.
and Rule 17(f) of the Arizona Rules of Civil Procedure; (f) any defense arising
by reason of any disability or other defense of Borrower or by reason of the
cessation from any cause whatsoever (other than payment in full) of the
liability of Borrower for the Indebtedness; and (g) the benefits of any
statutory provision limiting the right of the Lenders to recover a deficiency
judgment, or to otherwise proceed against any person or entity obligated for
payment of the Indebtedness, after any foreclosure or trustee's sale of any
security for the Indebtedness, including without limitation the benefits, if
any, to Guarantor of A.R.S.  Section 33-814 and Section 12-1566. Guarantor
hereby expressly consents to any impairment of collateral, including, but not
limited to, failure to perfect a security interest and release collateral and
any such impairment or release shall not affect Guarantor's obligations
hereunder. Until payment in full of the Indebtedness, Guarantor shall have no
right of subrogation and hereby waives any right to enforce any remedy which
the Lenders now have, or may hereafter have, against Borrower, and waives any
benefit of, and any right to participate in, any security held by





                                      -3-
<PAGE>   179

the Lenders.

         7. All existing and future indebtedness of Borrower to Guarantor is
hereby subordinated to the Indebtedness and such indebtedness of Borrower to
Guarantor, if the Lenders so request, shall be collected, enforced and received
by Guarantor as trustee for the Lenders and shall be paid over to the Lenders
on account of the Indebtedness, but without reducing or affecting in any manner
the liability of Guarantor under the other provisions of this Guarantee.


         8. In addition to all liens upon, and rights of setoff against, the
monies, securities or other property of Guarantor given to the Lenders by law,
the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor. No lien or right of setoff shall be deemed to have
been waived by any act or conduct on the part of the Administrative Agent or
the Lenders, by any neglect to exercise such right of setoff or to enforce such
lien, or by any delay in so doing.

         9. It is not necessary for the Lenders to inquire into the powers of
Borrower or the officers, directors, partners or agents acting or purporting to
act on its behalf, and any of the Indebtedness made or created in reliance upon
the professed exercise of such powers shall be guaranteed hereunder.

         10. Within one hundred twenty (120) days after the close of each
fiscal year of Guarantor, while this Guarantee remains in effect, Guarantor
shall deliver to the Lenders financial statements of Guarantor, all in
reasonable detail satisfactory to the Lenders. Such financial statements shall
be certified by Guarantor. While this Guarantee remains in effect, Guarantor
shall deliver to the Lenders copies of Guarantor's federal income tax returns
within thirty (30) days of each filing of such returns. When requested by the
Administrative Agent, from time to time, Guarantor shall promptly deliver, in
writing, such further information as the Administrative Agent may reasonably
request relating to any such financial statements or returns.

         11. Guarantor agrees to pay all attorneys' fees and all other costs
and expenses which may be incurred by the





                                      -4-

Administrative Agent or the Lenders in enforcing this Guarantee or in
collecting all or any part of the Indebtedness.  In the event of any court
proceedings, court costs and attorneys' fees shall be set by the court and not
by the jury and shall be included in any judgment obtained by the
Administrative Agent or the Lenders.


         12. This Guarantee sets forth the entire agreement of Guarantor and
the Lenders with respect to the subject matter hereof and supersedes all prior
oral and written agreements and representations by the Lenders to Guarantor. No
modification or waiver of any provision of this Guarantee or any right of the
Lenders hereunder and no release of Guarantor from any obligation hereunder
shall be effective unless in a writing executed by an authorized officer of
each of the Lenders. There are no conditions, oral or otherwise, on the
effectiveness of this Guarantee.

         13.      This Guarantee shall inure to the benefit of the Lenders and
their successors and assigns and shall be binding upon Guarantor and its heirs,
personal representatives, successors and assigns.  The Lenders may assign this
Guarantee in whole or in part without notice.

         14. This Guarantee shall be governed by and construed according to the
laws of the State of Arizona except that the laws of the state of Guarantor's
domicile shall govern the power of Guarantor to bind the marital community and
the community assets of Guarantor and Guarantor's spouse, or if the state of
Guarantor's domicile is not a community property state, the power of Guarantor
to bind the property of Guarantor's spouse, for the payment and performance of

provisions contained in Section 11.15 of the Loan Agreement.

this Guarantee, Guarantor hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid

TO:      BANK ONE, ARIZONA, NA

         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1.      FOR VALUABLE CONSIDERATION, the undersigned (hereinafter

         termination of Borrower's, Guarantor's or any other guarantor's
         liability by express or implied agreement with the Lenders or by
         operation of law and notwithstanding that the Indebtedness or any part
         thereof is deemed to have been paid or discharged by operation of law
         or by some act or agreement of the Lenders.  For purposes of this
         Guarantee, the Indebtedness shall be deemed to be paid only to the
<PAGE>   185
         extent that the Lenders actually receive immediately available funds
         and to the extent of any credit bid by the Lenders at any foreclosure
         or trustee's sale of any security for the Indebtedness.

                 (b)      Notwithstanding anything contained herein to the
         contrary, the recovery under this Guarantee with respect to the
         Indebtedness (which does not include any amounts recovered under
         Paragraph 11) shall be limited to One Hundred Fifty Thousand and
         No/100 Dollars ($150,000).

         3.      Guarantor agrees that to the extent Borrower or Guarantor
makes any payment to the Administrative Agent or the Lenders in connection with
the Indebtedness, and all or any part of such payment is subsequently
invalidated, declared to be fraudulent or preferential , set aside or required
to be repaid by the Administrative Agent or the Lenders or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then this Guarantee shall continue to be effective or shall be
reinstated, as the case may be, and, to the extent of such payment or repayment
by the Lenders (or the Administrative Agent, as the case may be), the
Indebtedness or part thereof intended to be satisfied by such Preferential
Payment shall be revived and continued in full force and effect as if said
Preferential Payment had not been made.

         4.      Guarantor is providing this Guarantee at the instance and
request of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower.  Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5.      Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)
renew, modify, compromise, extend, accelerate or otherwise change the time for
payment of, or otherwise change the terms of the Indebtedness or any part
thereof, including increasing or decreasing the rate of interest thereon; (b)
release, substitute or add any one or more endorsers or other guarantors; (c)
take and hold security for the payment of this Guarantee or the Indebtedness,
and enforce, exchange,





                                      -2-
<PAGE>   186

substitute, subordinate, waive or release any such security; (d) proceed
against such security and direct the order or manner of sale of such security
as the Lenders in their discretion may determine; and (e) apply any and all
payments from Borrower, Guarantor or any other guarantor, or recoveries from
such security, in such order or manner as the Lenders in their discretion may
determine.

         6.      Guarantor waives and agrees not to assert: (a) any right to
require the Lenders to proceed against Borrower or any other guarantor, to
proceed against or exhaust any security for the Indebtedness, to pursue any
other remedy available to the Lenders, or to pursue any remedy in any
particular order or manner; (b) the benefit of any statute of limitations
affecting Guarantor's liability hereunder or the enforcement hereof; (c)
demand, diligence, presentment for payment, protest and demand, and notice of
extension, dishonor, protest, demand, nonpayment and acceptance of this
Guarantee; (d) notice of the existence, creation or incurring of new or
additional indebtedness of Borrower to the Lenders; (e) the benefits of any
statutory provision limiting the liability of a surety, including without
limitation the provisions of A.R.S. Sections 12-1641, et seq. and Rule 17(f) of
the Arizona Rules of Civil Procedure; (f) any defense arising by reason of any
disability or other defense of Borrower or by reason of the cessation from any
cause whatsoever (other than payment in full) of the liability of Borrower for
the Indebtedness; and (g) the benefits of any statutory provision limiting the
right of the Lenders to recover a deficiency judgment, or to otherwise proceed
against any person or entity obligated for payment of the Indebtedness, after
any foreclosure or trustee's sale of any security for the Indebtedness,
including without limitation the benefits, if any, to Guarantor of A.R.S.
Section 33-814 and Section 12-1566.  Guarantor hereby expressly consents to any
impairment of collateral, including, but not limited to, failure to perfect a
security interest and release collateral and any such impairment or release
shall not affect Guarantor's obligations hereunder.  Until payment in full of
the Indebtedness, Guarantor shall have no right of subrogation and hereby
waives any right to enforce any remedy which the Lenders now have, or may
hereafter have, against Borrower, and waives any benefit of, and any right to
participate in, any security held by the Lenders.

         7.      All existing and future indebtedness of Borrower to Guarantor
is hereby subordinated to the Indebtedness and such indebtedness of Borrower to
Guarantor, if the Lenders so request, shall be collected, enforced and received
by Guarantor as trustee for the Lenders and shall be paid over to the Lenders
on account





                                      -3-
<PAGE>   187

of the Indebtedness, but without reducing or affecting in any manner the
liability of Guarantor under the other provisions of this Guarantee.

         8.      In addition to all liens upon, and rights of setoff against,
the monies, securities or other property of Guarantor given to the Lenders by
law, the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor.  No lien or right of setoff shall be deemed to
have been waived by any act or conduct on the part of the Administrative Agent
or the Lenders, by any neglect to exercise such right of setoff or to enforce
such lien, or by any delay in so doing.

         9.      It is not necessary for the Lenders to inquire into the powers
of Borrower or the officers, directors, partners or agents acting or purporting
to act on its behalf, and any of the Indebtedness made or created in reliance
upon the professed exercise of such powers shall be guaranteed hereunder.

         10.     Within one hundred twenty (120) days after the close of each
fiscal year of Guarantor, while this Guarantee remains in effect, Guarantor
shall deliver to the Lenders financial statements of Guarantor, all in
reasonable detail satisfactory to the Lenders.  Such financial statements shall
be certified by Guarantor.  When requested by the Administrative Agent, from
time to time, Guarantor shall promptly deliver, in writing, such further
information as the Administrative Agent may reasonably request relating to any
such financial statements.

         11.     Guarantor agrees to pay all attorneys' fees and all other
costs and expenses which may be incurred by the Administrative Agent or the
Lenders in enforcing this Guarantee or in collecting all or any part of the
Indebtedness.  In the event of any court proceedings, court costs and
attorneys' fees shall be set by the court and not by the jury and shall be
included in any judgment obtained by the Administrative Agent or the Lenders.

         12.     This Guarantee sets forth the entire agreement of Guarantor
and the Lenders with respect to the subject matter hereof and supersedes all
prior oral and written agreements and





                                      -4-
<PAGE>   188

representations by the Lenders to Guarantor.  No modification or waiver of any
provision of this Guarantee or any right of the Lenders hereunder and no
release of Guarantor from any obligation hereunder shall be effective unless in
a writing executed by an authorized officer of each of the Lenders.  There are
no conditions, oral or otherwise, on the effectiveness of this Guarantee.

         13.     This Guarantee shall inure to the benefit of the Lenders and
their successors and assigns and shall be binding upon Guarantor and its heirs,
personal representatives, successors and assigns.  The Lenders may assign this
Guarantee in whole or in part without notice.

         14.     This Guarantee shall be governed by and construed according to
the laws of the State of Arizona except that the laws of the state of
Guarantor's domicile shall govern the power of Guarantor to bind the marital
community and the community assets of Guarantor and Guarantor's spouse, or if
the state of Guarantor's domicile is not a community property state, the power
of Guarantor to bind the property of Guarantor's spouse, for the payment and
performance of the obligations under this Guarantee.  Guarantor represents and
warrants that the common domicile of Guarantor and Guarantor's spouse is in the
State of Minnesota.

         15.     Guarantor covenants and agrees to be bound by the arbitration
provisions contained in Section 11.15 of the Loan Agreement.

         16.     Any legal action or proceeding with respect to this Guarantee
or any document related hereto may be brought in Arizona State or United States
District Court sitting in Phoenix, Arizona, and, by execution and delivery of
this Guarantee, Guarantor hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts. Guarantor hereby irrevocably waives any objection, including, without
limitation, any objection to the laying of venue or based on the grounds of
forum non conveniens, which Guarantor may now or hereafter have to the bringing
of any such action or proceeding in such respective jurisdictions. Guarantor
irrevocably consents to the service of process of any of the aforesaid courts in
any such action or proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, to Guarantor at its address provided herein.
Nothing contained in this paragraph shall affect the right of the Administrative
Agent, any Lender or any holder of a Note to serve process in any other manner
permitted by law or commence legal proceedings or otherwise proceed against
Guarantor in any other

                       UNCONDITIONAL GUARANTEE OF PAYMENT
                               (GERALD N. CLARK)

TO:      BANK ONE, ARIZONA, NA
         CREDIT LYONNAIS NEW YORK BRANCH
         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1.      FOR VALUABLE CONSIDERATION, the undersigned (hereinafter
called "Guarantor"), whose address is set forth after Guarantor's signature
below, unconditionally guarantees and promises to pay to the Lenders (under and
as defined in that certain Revolving Credit Agreement (as modified, amended or
restated from time to time, the "Loan Agreement"), dated of even date herewith,
by and among Bank One, Arizona, NA, Credit Lyonnais New York Branch and Wells
Fargo Bank, National Association (each a "Lender" and collectively, the
"Lenders") and Sunstone Hotel Investors, L.P., a Delaware limited partnership
(the "Borrower"); capitalized terms used herein but not defined herein shall
have the meaning provided for such terms in the Loan Agreement), or order, upon
demand, in lawful money of the United States, the full and prompt payment when
due, whether at maturity or earlier, by reason of acceleration or otherwise,
and at all times thereafter (i) the principal of and interest on the Loans and
(ii) all other Obligations arising under any Loan Document (all such guaranteed
amounts are hereinafter collectively called the "Indebtedness").

         2.      (a) The obligations of Guarantor hereunder, are separate and
         independent of the obligations of Borrower and of any other guarantor,
         and a separate action or actions may be brought and prosecuted against
         Guarantor whether action is brought against Borrower or any other
         guarantor or whether Borrower or any other guarantor is joined in any
         action or actions.  The obligations of Guarantor hereunder shall
         survive and continue in full force and effect until payment in full of
         the Indebtedness is actually received by the Lenders and the period of
         time has expired during which any payment made by Borrower, Guarantor
         or any other guarantor to the Lenders may be determined to be a
         Preferential Payment (defined below), notwithstanding any release or
         termination of Borrower's, Guarantor's or any other guarantor's
         liability by express or implied agreement with the Lenders or by
         operation of law and notwithstanding that the Indebtedness or any part
         thereof is deemed to have been paid or discharged by operation of law
         or by some act or agreement of the Lenders.  For purposes of this
         Guarantee, the Indebtedness shall be deemed to be paid only to the






<PAGE>   193

         extent that the Lenders actually receive immediately available funds
         and to the extent of any credit bid by the Lenders at any foreclosure
         or trustee's sale of any security for the Indebtedness.

                 (b)      Notwithstanding anything contained herein to the
         contrary, the recovery under this Guarantee with respect to the
         Indebtedness (which does not include any amounts recovered under
         Paragraph 11) shall be limited to Sixty Thousand and No/100 Dollars
         ($60,000).

         3.      Guarantor agrees that to the extent Borrower or Guarantor
makes any payment to the Administrative Agent or the Lenders in connection with
the Indebtedness, and all or any part of such payment is subsequently
invalidated, declared to be fraudulent or preferential , set aside or required
to be repaid by the Administrative Agent or the Lenders or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then this Guarantee shall continue to be effective or shall be
reinstated, as the case may be, and, to the extent of such payment or repayment
by the Lenders (or the Administrative Agent, as the case may be), the
Indebtedness or part thereof intended to be satisfied by such Preferential
Payment shall be revived and continued in full force and effect as if said
Preferential Payment had not been made.

         4.      Guarantor is providing this Guarantee at the instance and
request of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower.  Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5.      Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)
renew, modify, compromise, extend, accelerate or otherwise change the time for
payment of, or otherwise change the terms of the Indebtedness or any part
thereof, including increasing or decreasing the rate of interest thereon; (b)
release, substitute or add any one or more endorsers or other guarantors; (c)

proceed against such security and direct the order or manner of sale of such
security as the Lenders in their discretion may determine; and (e) apply any
and all payments from Borrower, Guarantor or any other guarantor, or recoveries
from such security, in such order or manner as the Lenders in their discretion
may determine.

         6.      Guarantor waives and agrees not to assert: (a) any right to
require the Lenders to proceed against Borrower or any other guarantor, to
proceed against or exhaust any security for the Indebtedness, to pursue any
other remedy available to the Lenders, or to pursue any remedy in any
particular order or manner; (b) the benefit of any statute of limitations
affecting Guarantor's liability hereunder or the enforcement hereof; (c)
demand, diligence, presentment for payment, protest and demand, and notice of
extension, dishonor, protest, demand, nonpayment and acceptance of this
Guarantee; (d) notice of the existence, creation or incurring of new or
additional indebtedness of Borrower to the Lenders; (e) the benefits of any
statutory provision limiting the liability of a surety, including without
limitation the provisions of A.R.S. Sections 12-1641, et seq. and Rule 17(f) of
the Arizona Rules of Civil Procedure; (f) any defense arising by reason of any
disability or other defense of Borrower or by reason of the cessation from any
cause whatsoever (other than payment in full) of the liability of Borrower for
the Indebtedness; and (g) the benefits of any statutory provision limiting the
right of the Lenders to recover a deficiency judgment, or to otherwise proceed
against any person or entity obligated for payment of the Indebtedness, after
any foreclosure or trustee's sale of any security for the Indebtedness,
including without limitation the benefits, if any, to Guarantor of A.R.S.
Section 33-814 and Section 12-1566.  Guarantor hereby expressly consents to any
impairment of collateral, including, but not limited to, failure to perfect a
security interest and release collateral and any such impairment or release
shall not affect Guarantor's obligations hereunder.  Until payment in full of
the Indebtedness, Guarantor shall have no right of subrogation and hereby
waives any right to enforce any remedy which the Lenders now have, or may
hereafter have, against Borrower, and waives any benefit of, and any right to
participate in, any security held by the Lenders.

         7.      All existing and future indebtedness of Borrower to Guarantor
is hereby subordinated to the Indebtedness and such indebtedness of Borrower to
Guarantor, if the Lenders so request, shall be collected, enforced and received
by Guarantor as trustee for the Lenders and shall be paid over to the Lenders
on account of the Indebtedness, but without reducing or affecting in any





                                      -3-
<PAGE>   195
manner the liability of Guarantor under the other provisions of this Guarantee.

         8.      In addition to all liens upon, and rights of setoff against,
the monies, securities or other property of Guarantor given to the Lenders by
law, the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor.  No lien or right of setoff shall be deemed to
have been waived by any act or conduct on the part of the Administrative Agent
or the Lenders, by any neglect to exercise such right of setoff or to enforce
such lien, or by any delay in so doing.

         9.      It is not necessary for the Lenders to inquire into the powers
of Borrower or the officers, directors, partners or agents acting or purporting
to act on its behalf, and any of the Indebtedness made or created in reliance
upon the professed exercise of such powers shall be guaranteed hereunder.

         10.     Within one hundred twenty (120) days after the close of each
fiscal year of Guarantor, while this Guarantee remains in effect, Guarantor
shall deliver to the Lenders financial statements of Guarantor, all in
reasonable detail satisfactory to the Lenders.  Such financial statements shall
be certified by Guarantor.  When requested by the Administrative Agent, from
time to time, Guarantor shall promptly deliver, in writing, such further
information as the Administrative Agent may reasonably request relating to any
such financial statements.

costs and expenses which may be incurred by the Administrative Agent or the
Lenders in enforcing this Guarantee or in collecting all or any part of the

attorneys' fees shall be set by the court and not by the jury and shall be
included in any judgment obtained by the Administrative Agent or the Lenders.

         12.     This Guarantee sets forth the entire agreement of Guarantor

community and the community assets of Guarantor and Guarantor's spouse, or if

                       UNCONDITIONAL GUARANTEE OF PAYMENT
                               (C. ROBERT ENEVER)

TO:      BANK ONE, ARIZONA, NA
         CREDIT LYONNAIS NEW YORK BRANCH
         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1.      FOR VALUABLE CONSIDERATION, the undersigned (hereinafter
called "Guarantor"), whose address is set forth after Guarantor's signature
below, unconditionally guarantees and promises to pay to the Lenders (under and
as defined in that certain Revolving Credit Agreement (as modified, amended or
restated from time to time, the "Loan Agreement"), dated of even date herewith,
by and among Bank One, Arizona, NA, Credit Lyonnais New York Branch and Wells
Fargo Bank, National Association (each a "Lender" and collectively, the
"Lenders") and Sunstone Hotel Investors, L.P., a Delaware limited partnership
(the "Borrower"); capitalized terms used herein but not defined herein shall
have the meaning provided for such terms in the Loan Agreement), or order, upon
demand, in lawful money of the United States, the full and prompt payment when
due, whether at maturity or earlier, by reason of acceleration or otherwise,
and at all times thereafter (i) the principal of and interest on the Loans and
(ii) all other Obligations arising under any Loan Document (all such guaranteed
amounts are hereinafter collectively called the "Indebtedness").

         2.      (a) The obligations of Guarantor hereunder, are separate and
         independent of the obligations of Borrower and of any other guarantor,
         and a separate action or actions may be brought and prosecuted against
         Guarantor whether action is brought against Borrower or any other
         guarantor or whether Borrower or any other guarantor is joined in any
         action or actions.  The obligations of Guarantor hereunder shall
         survive and continue in full force and effect until payment in full of
         the Indebtedness is actually received by the Lenders and the period of
         time has expired during which any payment made by Borrower, Guarantor
         or any other guarantor to the Lenders may be determined to be a
         Preferential Payment (defined below), notwithstanding any release or
         termination of Borrower's, Guarantor's or any other guarantor's
         liability by express or implied agreement with the Lenders or by
         operation of law and notwithstanding that the Indebtedness or any part
         thereof is deemed to have been paid or discharged by operation of law
         or by some act or agreement of the Lenders.  For purposes of this
         Guarantee, the Indebtedness shall be deemed to be paid only to the






<PAGE>   201

         extent that the Lenders actually receive immediately available funds
         and to the extent of any credit bid by the Lenders at any foreclosure
         or trustee's sale of any security for the Indebtedness.

                 (b)      Notwithstanding anything contained herein to the
         contrary, the recovery under this Guarantee with respect to the
         Indebtedness (which does not include any amounts recovered under
         Paragraph 11) shall be limited to Five Hundred Thousand and No/100
         Dollars ($500,000).

         3.      Guarantor agrees that to the extent Borrower or Guarantor
makes any payment to the Administrative Agent or the Lenders in connection with
the Indebtedness, and all or any part of such payment is subsequently
invalidated, declared to be fraudulent or preferential , set aside or required
to be repaid by the Administrative Agent or the Lenders or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then this Guarantee shall continue to be effective or shall be
reinstated, as the case may be, and, to the extent of such payment or repayment
by the Lenders (or the Administrative Agent, as the case may be), the
Indebtedness or part thereof intended to be satisfied by such Preferential
Payment shall be revived and continued in full force and effect as if said
Preferential Payment had not been made.

         4.      Guarantor is providing this Guarantee at the instance and
request of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower.  Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5.      Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)
renew, modify, compromise, extend, accelerate or otherwise change the time for
payment of, or otherwise change the terms of the Indebtedness or any part
thereof, including increasing or decreasing the rate of interest thereon; (b)
release, substitute or add any one or more endorsers or other guarantors; (c)
take and hold security for the payment of this Guarantee or the Indebtedness,
and enforce, exchange, substitute, subordinate, waive or release any such
security; (d)





                                      -2-
<PAGE>   202
proceed against such security and direct the order or manner of sale of such
security as the Lenders in their discretion may determine; and (e) apply any
and all payments from Borrower, Guarantor or any other guarantor, or recoveries
from such security, in such order or manner as the Lenders in their discretion
may determine.

         6.      Guarantor waives and agrees not to assert: (a) any right to
require the Lenders to proceed against Borrower or any other guarantor, to
proceed against or exhaust any security for the Indebtedness, to pursue any
other remedy available to the Lenders, or to pursue any remedy in any
particular order or manner; (b) the benefit of any statute of limitations
affecting Guarantor's liability hereunder or the enforcement hereof; (c)
demand, diligence, presentment for payment, protest and demand, and notice of
extension, dishonor, protest, demand, nonpayment and acceptance of this
Guarantee; (d) notice of the existence, creation or incurring of new or
additional indebtedness of Borrower to the Lenders; (e) the benefits of any
statutory provision limiting the liability of a surety, including without
limitation the provisions of A.R.S. Sections 12-1641, et seq. and Rule 17(f) of
the Arizona Rules of Civil Procedure; (f) any defense arising by reason of any
disability or other defense of Borrower or by reason of the cessation from any
cause whatsoever (other than payment in full) of the liability of Borrower for
the Indebtedness; and (g) the benefits of any statutory provision limiting the
right of the Lenders to recover a deficiency judgment, or to otherwise proceed
against any person or entity obligated for payment of the Indebtedness, after
any foreclosure or trustee's sale of any security for the Indebtedness,
including without limitation the benefits, if any, to Guarantor of A.R.S.
Section 33-814 and Section 12-1566.  Guarantor hereby expressly consents to any
impairment of collateral, including, but not limited to, failure to perfect a
security interest and release collateral and any such impairment or release
shall not affect Guarantor's obligations hereunder.  Until payment in full of
the Indebtedness, Guarantor shall have no right of subrogation and hereby
waives any right to enforce any remedy which the Lenders now have, or may
hereafter have, against Borrower, and waives any benefit of, and any right to
participate in, any security held by the Lenders.

         7.      All existing and future indebtedness of Borrower to Guarantor
is hereby subordinated to the Indebtedness and such indebtedness of Borrower to
Guarantor, if the Lenders so request, shall be collected, enforced and received
by Guarantor as trustee for the Lenders and shall be paid over to the Lenders
on account of the Indebtedness, but without reducing or affecting in any





                                      -3-
<PAGE>   203
manner the liability of Guarantor under the other provisions of this Guarantee.

         8.      In addition to all liens upon, and rights of setoff against,
the monies, securities or other property of Guarantor given to the Lenders by
law, the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor.  No lien or right of setoff shall be deemed to
have been waived by any act or conduct on the part of the Administrative Agent
or the Lenders, by any neglect to exercise such right of setoff or to enforce
such lien, or by any delay in so doing.

         9.      It is not necessary for the Lenders to inquire into the powers
of Borrower or the officers, directors, partners or agents acting or purporting
to act on its behalf, and any of the Indebtedness made or created in reliance
upon the professed exercise of such powers shall be guaranteed hereunder.

         10.     Within one hundred twenty (120) days after the close of each
fiscal year of Guarantor, while this Guarantee remains in effect, Guarantor
shall deliver to the Lenders financial statements of Guarantor, all in
reasonable detail satisfactory to the Lenders.  Such financial statements shall
be certified by Guarantor.  When requested by the Administrative Agent, from
time to time, Guarantor shall promptly deliver, in writing, such further
information as the Administrative Agent may reasonably request relating to any
such financial statements.

         11.     Guarantor agrees to pay all attorneys' fees and all other
costs and expenses which may be incurred by the Administrative Agent or the
Lenders in enforcing this Guarantee or in collecting all or any part of the
Indebtedness.  In the event of any court proceedings, court costs and
attorneys' fees shall be set by the court and not by the jury and shall be
included in any judgment obtained by the Administrative Agent or the Lenders.

         12.     This Guarantee sets forth the entire agreement of Guarantor
and the Lenders with respect to the subject matter hereof and supersedes all
prior oral and written agreements and representations by the Lenders to
Guarantor.  No modification or waiver of any provision of this Guarantee or any
right of the





                                      -4-
<PAGE>   204
Lenders hereunder and no release of Guarantor from any obligation hereunder
shall be effective unless in a writing executed by an authorized officer of
each of the Lenders.  There are no conditions, oral or otherwise, on the
effectiveness of this Guarantee.

         13.     This Guarantee shall inure to the benefit of the Lenders and
their successors and assigns and shall be binding upon Guarantor and its heirs,
personal representatives, successors and assigns.  The Lenders may assign this
Guarantee in whole or in part without notice.

         14.     This Guarantee shall be governed by and construed according to
the laws of the State of Arizona except that the laws of the state of
Guarantor's domicile shall govern the power of Guarantor to bind the marital
community and the community assets of Guarantor and Guarantor's spouse, or if
the state of Guarantor's domicile is not a community property state, the power
of Guarantor to bind the property of Guarantor's spouse, for the payment and
performance of the obligations under this Guarantee.  Guarantor represents and
warrants that the common domicile of Guarantor and Guarantor's spouse is in the
State of Colorado.

         15.     Guarantor covenants and agrees to be bound by the arbitration
provisions contained in Section 11.15 of the Loan Agreement.

         16.     Any legal action or proceeding with respect to this Guarantee
or any document related hereto may be brought in Arizona State or United States
District Court sitting in Phoenix, Arizona, and, by execution and delivery of
this Guarantee, Guarantor hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts.  Guarantor hereby irrevocably waives any objection, including, without
limitation, any objection to the laying of venue or based on the grounds of
forum non conveniens, which Guarantor may now or hereafter have to the bringing
of any such action or proceeding in such respective jurisdictions.  Guarantor
irrevocably consents to the service of process of any of the aforesaid courts
in any such action or proceeding by the mailing of copies thereof by registered
or certified mail, postage prepaid, to Guarantor at its address provided
herein.  Nothing contained in this paragraph shall affect the right of the
Administrative Agent, any Lender or any holder of a Note to serve process in
any other manner permitted by law or commence legal proceedings or otherwise
proceed against Guarantor in any other jurisdiction.

                       UNCONDITIONAL GUARANTEE OF PAYMENT
                                (SHIVANI, L.L.C.)

TO:      BANK ONE, ARIZONA, NA
         CREDIT LYONNAIS NEW YORK BRANCH
         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1.      FOR VALUABLE CONSIDERATION, the undersigned (hereinafter
called "Guarantor"), whose principal office is set forth after Guarantor's
signature below, unconditionally guarantees and promises to pay to the Lenders
(under and as defined in that certain Revolving Credit Agreement (as modified,
amended or restated from time to time, the "Loan Agreement"), dated of even
date herewith, by and among Bank One, Arizona, NA, Credit Lyonnais New York
Branch and Wells Fargo Bank, National Association (each a "Lender" and
collectively, the "Lenders") and Sunstone Hotel Investors, L.P., a Delaware
limited partnership (the "Borrower"); capitalized terms used herein but not
defined herein shall have the meaning provided for such terms in the Loan
Agreement), or order, upon demand, in lawful money of the United States, the
full and prompt payment when due, whether at maturity or earlier, by reason of
acceleration or otherwise, and at all times thereafter (i) the principal of and
interest on the Loans and (ii) all other Obligations arising under any Loan
Document (all such guaranteed amounts are hereinafter collectively called the
"Indebtedness").

         2.      (a) The obligations of Guarantor hereunder, are separate and
         independent of the obligations of Borrower and of any other guarantor,
         and a separate action or actions may be brought and prosecuted against
         Guarantor whether action is brought against Borrower or any other
         guarantor or whether Borrower or any other guarantor is joined in any
         action or actions.  The obligations of Guarantor hereunder shall
         survive and continue in full force and effect until payment in full of
         the Indebtedness is actually received by the Lenders and the period of
         time has expired during which any payment made by Borrower, Guarantor
         or any other guarantor to the Lenders may be determined to be a
         Preferential Payment (defined below), notwithstanding any release or
         termination of Borrower's, Guarantor's or any other guarantor's
         liability by express or implied agreement with the Lenders or by
         operation of law and notwithstanding that the Indebtedness or any part
         thereof is deemed to have been paid or discharged by operation of law
         or by some act or agreement of the Lenders.  For purposes of this
         Guarantee, the Indebtedness shall be deemed to be paid only to the






<PAGE>   209
         extent that the Lenders actually receive immediately available funds
         and to the extent of any credit bid by the Lenders at any foreclosure
         or trustee's sale of any security for the Indebtedness.

                 (b)      Notwithstanding anything contained herein to the
         contrary, the recovery under this Guarantee with respect to the
         Indebtedness (which does not include any amounts recovered under
         Paragraph 11) shall be limited to Five Million Eight Hundred Thousand
         and No/100 Dollars (5,800,000).

         3.      Guarantor agrees that to the extent Borrower or Guarantor
makes any payment to the Administrative Agent or the Lenders in connection with
the Indebtedness, and all or any part of such payment is subsequently
invalidated, declared to be fraudulent or preferential , set aside or required
to be repaid by the Administrative Agent or the Lenders or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then this Guarantee shall continue to be effective or shall be
reinstated, as the case may be, and, to the extent of such payment or repayment
by the Lenders (or the Administrative Agent, as the case may be), the
Indebtedness or part thereof intended to be satisfied by such Preferential
Payment shall be revived and continued in full force and effect as if said
Preferential Payment had not been made.

         4.      Guarantor is providing this Guarantee at the instance and
request of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower.  Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5.      Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)
renew, modify, compromise, extend, accelerate or otherwise change the time for
payment of, or otherwise change the terms of the Indebtedness or any part
thereof, including increasing or decreasing the rate of interest thereon; (b)
release, substitute or add any one or more endorsers or other guarantors; (c)
take and hold security for the payment of this Guarantee or the Indebtedness,
and enforce, exchange,





                                      -2-
<PAGE>   210
substitute, subordinate, waive or release any such security; (d) proceed
against such security and direct the order or manner of sale of such security
as the Lenders in their discretion may determine; and (e) apply any and all
payments from Borrower, Guarantor or any other guarantor, or recoveries from
such security, in such order or manner as the Lenders in their discretion may
determine.

         6.      Guarantor waives and agrees not to assert: (a) any right to
require the Lenders to proceed against Borrower or any other guarantor, to
proceed against or exhaust any security for the Indebtedness, to pursue any
other remedy available to the Lenders, or to pursue any remedy in any
particular order or manner; (b) the benefit of any statute of limitations
affecting Guarantor's liability hereunder or the enforcement hereof; (c)
demand, diligence, presentment for payment, protest and demand, and notice of
extension, dishonor, protest, demand, nonpayment and acceptance of this
Guarantee; (d) notice of the existence, creation or incurring of new or
additional indebtedness of Borrower to the Lenders; (e) the benefits of any
statutory provision limiting the liability of a surety, including without
limitation the provisions of A.R.S. Sections 12-1641, et seq. and Rule 17(f) of
the Arizona Rules of Civil Procedure; (f) any defense arising by reason of any
disability or other defense of Borrower or by reason of the cessation from any
cause whatsoever (other than payment in full) of the liability of Borrower for
the Indebtedness; and (g) the benefits of any statutory provision limiting the
right of the Lenders to recover a deficiency judgment, or to otherwise proceed
against any person or entity obligated for payment of the Indebtedness, after
any foreclosure or trustee's sale of any security for the Indebtedness,
including without limitation the benefits, if any, to Guarantor of A.R.S.
Section 33-814 and Section 12-1566.  Guarantor hereby expressly consents to any
impairment of collateral, including, but not limited to, failure to perfect a
security interest and release collateral and any such impairment or release
shall not affect Guarantor's obligations hereunder.  Until payment in full of
the Indebtedness, Guarantor shall have no right of subrogation and hereby
waives any right to enforce any remedy which the Lenders now have, or may
hereafter have, against Borrower, and waives any benefit of, and any right to
participate in, any security held by the Lenders.

         7.      All existing and future indebtedness of Borrower to Guarantor
is hereby subordinated to the Indebtedness and such indebtedness of Borrower to
Guarantor, if the Lenders so request, shall be collected, enforced and received
by Guarantor as trustee for the Lenders and shall be paid over to the Lenders
on account





                                      -3-
<PAGE>   211
of the Indebtedness, but without reducing or affecting in any manner the
liability of Guarantor under the other provisions of this Guarantee.

         8.      In addition to all liens upon, and rights of setoff against,
the monies, securities or other property of Guarantor given to the Lenders by
law, the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor.  No lien or right of setoff shall be deemed to
have been waived by any act or conduct on the part of the Administrative Agent
or the Lenders, by any neglect to exercise such right of setoff or to enforce
such lien, or by any delay in so doing.

         9.      It is not necessary for the Lenders to inquire into the powers
of Borrower or the officers, directors, partners or agents acting or purporting
to act on its behalf, and any of the Indebtedness made or created in reliance
upon the professed exercise of such powers shall be guaranteed hereunder.

         10.     Within one hundred twenty (120) days after the close of each
fiscal year of Guarantor, while this Guarantee remains in effect, Guarantor

         CREDIT LYONNAIS NEW YORK BRANCH
         WELLS FARGO BANK, NATIONAL ASSOCIATION

         1.      FOR VALUABLE CONSIDERATION, the undersigned (hereinafter

interest on the Loans and (ii) all other Obligations arising under any Loan
Document.

         (b)     Unconditionally guarantees to the Lenders the performance by

to have been paid or discharged by operation of law or by some act or agreement
of the Lenders.  For purposes of this Guarantee, the Guaranteed Obligations
arising under Paragraph 1(a)  shall be deemed to be paid only to the extent
that the Lenders actually receive immediately available funds and to the extent
of any credit bid by the Lenders at any foreclosure or trustee's sale of any
security for the Guaranteed Obligations.

         (b)  If Guarantor fails to promptly perform its obligations under this
Guarantee arising under Paragraph 1(b), the Lenders shall have the following
remedies:

         do so, to proceed to perform on behalf of Guarantor any or all of
         Guarantor's obligations hereunder and Guarantor shall, upon demand and
         whether or not the construction, development, renovation, alterations
         and remodeling work is actually completed by the Lenders, pay to the
         Lenders all sums expended by the Lenders in performing Guarantor's
         obligations hereunder (all such sums shall constitute Obligations
         under the Loan Documents).

                 (ii)     From time to time and without first requiring
         performance by Borrower or exhausting any or all security for the
         Loan, to bring any action at law or in equity or both to compel
         Guarantor to perform its obligations hereunder, and to collect in any
         such action compensation for all loss, cost, damage, injury and
         expense sustained or incurred by the Lenders as a direct or indirect
         consequence of the failure of Guarantor to perform its obligations
         (all such sums shall constitute Obligations under the Loan Documents).

         3.      Guarantor agrees that to the extent Borrower or Guarantor
makes any payment to the Administrative Agent or the Lenders in connection with
the Guaranteed Obligations, and all or any part of such payment is subsequently
invalidated, declared to be fraudulent or preferential , set aside or required
to be repaid by the Administrative Agent or the Lenders or paid over to





                                      -2-
<PAGE>   222
a trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then this Guarantee shall continue to be effective or shall be
reinstated, as the case may be, and, to the extent of such payment or repayment
by the Lenders (or the Administrative Agent, as the case may be), the
Guaranteed Obligations or part thereof intended to be satisfied by such
Preferential Payment shall be revived and continued in full force and effect as
if said Preferential Payment had not been made.

         4.      Guarantor is providing this Guarantee at the instance and
request of Borrower to induce the Lenders to extend or continue financial
accommodations to Borrower.  Guarantor hereby represents and warrants that
Guarantor is and will continue to be fully informed about all aspects of the
financial condition and business affairs of Borrower that Guarantor deems
relevant to the obligations of Guarantor hereunder and hereby waives and fully
discharges the Lenders from any and all obligations to communicate to Guarantor
any information whatsoever regarding Borrower or Borrower's financial condition
or business affairs.

         5.      Guarantor authorizes the Lenders, without notice or demand and
without affecting Guarantor's liability hereunder, from time to time, to: (a)

discretion may determine; and (e) apply any and all payments from Borrower,
Guarantor or any other guarantor, or recoveries from such security, in such
order or manner as the Lenders in their discretion may determine.

         6.      Guarantor waives and agrees not to assert: (a) any right to
require the Lenders to proceed against Borrower or any other guarantor, to
proceed against or exhaust any security for the Guaranteed Obligations, to
pursue any other remedy available to the Lenders, or to pursue any remedy in
any particular order or manner; (b) the benefit of any statute of limitations
affecting Guarantor's liability hereunder or the enforcement hereof; (c)
demand, diligence, presentment for payment, protest and demand, and notice of
extension, dishonor, protest, demand,





                                      -3-

creation or incurring of new or additional indebtedness of Borrower to the
Lenders; (e) the benefits of any statutory provision limiting the liability of
a surety, including without limitation the provisions of A.R.S. Sections
12-1641, et seq. and Rule 17(f) of the Arizona Rules of Civil Procedure; (f)
any defense arising by reason of any disability or other defense of Borrower or
by reason of the cessation from any cause whatsoever (other than payment in
full) of the liability of Borrower for the Guaranteed Obligations; and (g) the
benefits of any statutory provision limiting the right of the Lenders to
recover a deficiency judgment, or to otherwise proceed against any person or
entity obligated for payment of the Guaranteed Obligations, after any
foreclosure or trustee's sale of any security for the Guaranteed Obligations,
including without limitation the benefits, if any, to Guarantor of A.R.S.
Section 33-814 and Section 12-1566.  Guarantor hereby expressly consents to any
impairment of collateral, including, but not limited to, failure to perfect a
security interest and release collateral and any such impairment or release
shall not affect Guarantor's obligations hereunder.  Until payment in full of
the Guaranteed Obligations, Guarantor shall have no right of subrogation and
hereby waives any right to enforce any remedy which the Lenders now have, or
may hereafter have, against Borrower, and waives any benefit of, and any right
to participate in, any security held by the Lenders.

         7.      All existing and future indebtedness of Borrower to Guarantor
is hereby subordinated to the Guaranteed Obligations and such indebtedness of
Borrower to Guarantor, if the Lenders so request, shall be collected, enforced
and received by Guarantor as trustee for the Lenders and shall be paid over to
the Lenders on account of the Guaranteed Obligations, but without reducing or
affecting in any manner the liability of Guarantor under the other provisions
of this Guarantee.

         8.      In addition to all liens upon, and rights of setoff against,
the monies, securities or other property of Guarantor given to the Lenders by
law, the Lenders shall have a lien and a right of setoff against, and Guarantor
hereby grants to the Administrative Agent, for the benefit of the Lenders, a
security interest in, all monies, securities and other property of Guarantor
now or hereafter in the possession of or on deposit with any of the Lenders,
whether held in a general or special account or deposit, or for safekeeping or
otherwise; every such lien and right of setoff may be exercised without demand
upon or notice to Guarantor.  No lien or right of setoff shall be deemed to
have been waived by any act or conduct on the part of the





                                      -4-
<PAGE>   224
Administrative Agent or the Lenders, by any neglect to exercise such right of
setoff or to enforce such lien, or by any delay in so doing.

         9.      It is not necessary for the Lenders to inquire into the powers
of Borrower or the officers, directors, partners or agents acting or purporting
to act on its behalf, and any of the Guaranteed Obligations made or created in
reliance upon the professed exercise of such powers shall be guaranteed
hereunder.

         10.     While this Guarantee remains in effect, Guarantor shall
deliver to the Lenders copies of Guarantor's federal income tax returns upon
filing of such returns.  When requested by the Administrative Agent, from time
to time, Guarantor shall promptly deliver, in writing, such further information
as the Administrative Agent may reasonably request relating to any such
returns.

and interest in and to the following document or instrument:  Management
Agreement dated ______________, together with all obligations of Sunstone Hotel
Management, Inc. (hereinafter called "Management Company") due or to be
performed thereunder or with respect thereto (all hereinafter called the

         TO HAVE AND TO HOLD the same from this day forward so long as any part
of the obligations of Borrower hereinafter described remains unpaid and
unperformed.

         This Assignment is made as and shall constitute collateral security
for any and all indebtedness and liabilities of any kind and nature of Borrower
to the Lenders, direct or indirect, absolute or contingent, due or to become
due, now existing or hereafter arising, pursuant to the Loan Agreement (all of
the foregoing hereinafter called the "Obligation").

         1.      Assignor represents, warrants and covenants that:

                 (a)      The Management Agreement, as of the date hereof, is
         valid and in good and current standing, not having been altered,
         amended, changed, terminated or cancelled in any way, and no breach or
         default exists therein or thereunder.

                 (b)      Assignor had full power, right and authority to
         execute and deliver the Management Agreement and has full power, right
         and authority to execute and deliver this Assignment.

                 (c)      Assignor has not conveyed, transferred, or assigned
         the Management Agreement or any right or interest therein and has not
         executed any






<PAGE>   242

         other document or instrument that might prevent or limit Assignee from
         operating under the terms, conditions and provisions of this
         Assignment.

                 (d)      Assignor shall make no other assignment of the
         Management Agreement or of any right or interest therein.

                 (e)      Assignor shall perform and observe, in timely
         fashion, all of the covenants, conditions, obligations and agreements
         of Assignor under the Management Agreement in strict accordance with
         the terms, conditions and provisions thereof.

                 (f)      Assignor shall not waive, execute any agreement that
         could be interpreted as waiving, or in any manner release or discharge
         Management Company from, any covenants, conditions, obligations or
         agreements under or related to the Management Agreement to be
         performed or observed by Management Company, or condone any
         nonperformance thereof, but shall, at its sole cost and expense,
         enforce and secure the performance of all such covenants, conditions,
         obligations and agreements under or related to the Management
         Agreement to be performed or observed by Management Company.

         2.      Assignor hereby authorizes Assignee, upon the occurrence of
any Event of Default, as that term is defined in the Loan Agreement or any
document or instrument securing the Obligation, and at any time while such
Event of Default is continuing, or upon any default by Assignor under the
Management Agreement that remains uncured after the expiration of any grace
period provided therein, and upon the election by Assignee to exercise its
rights under this Assignment, to enforce Assignor's rights under the Management
Agreement and to receive any performance of Management Company thereunder.
Assignor hereby authorizes Management Company to accept this Assignment and
authorizes and directs Management Company, upon such default and election by
Assignee, to make and render all acts and performances required of Management
Company under the terms of the Management Agreement directly to Assignee or its
nominee as Assignee may direct.  Assignor hereby relieves Management Company
from any liabilities to Assignor that Assignor might otherwise have or assert
by reason of the making or rendering of any performance by Management Company
under the Management Agreement to Assignee or its nominee.

         3.      Assignor does hereby make, constitute and appoint Assignee,
and its successors and assigns, Assignor's true and lawful attorney in fact, in
Assignor's name, place and stead, or otherwise, upon the occurrence of any
Event of Default, and at any time while such Event of Default is continuing, or
upon any default by Assignor under the Management Agreement that remains
uncured after the expiration of any grace period provided therein:

                 (a)      To do all acts and to execute, acknowledge, obtain
         and deliver any and all instruments, documents, items or things
         necessary, proper or required as a term, condition or provision of the
         Management Agreement or in order to exercise any rights of Assignor
         under the Management Agreement or to receive and enforce any
         performance due Assignor under the Management Agreement;





                                      -2-
<PAGE>   243

                 (b)      To give any notices, instructions, or other
         communications to Management Company or to any other person or entity
         in connection with the Management Agreement;

                 (c)      To demand and receive all performances due under or
         with respect to the Management Agreement and to take all lawful ways
         and means for the enforcement thereof and to compromise and settle any
         claim or cause of action in Assignor arising from or related to the
         Management Agreement and give acquittance and other sufficient
         discharges relating thereto; and

                 (d)      To file any claim or proceeding or to take any other
         action, either in its own name, in that of its nominee, in the name of
         Assignor, or otherwise, to enforce performance due under or related to
         the Management Agreement or protect and preserve the right and
         interest of Assignee hereunder.

The power of attorney given herein is a power coupled with an interest and
shall be irrevocable so long as any part of the Obligation remains unpaid or
unperformed.  Assignee shall have no obligation to exercise any of the
foregoing rights and powers in any event.

         4.      Except as otherwise permitted in the Loan Agreement, no
change, amendment or modification shall be made to the Management Agreement or
to the instructions of Assignor contained herein without the prior written
approval of Assignee.

         5.      Assignor shall promptly notify Assignee of any default or
breach under the Management Agreement or of any failure of performance or other
condition that, after notice or lapse of time, or both, could become a default
or breach by Management Company of or under the Management Agreement.

         6.      Assignor, immediately upon receipt, shall deliver to Assignee
at the address set forth above a true and complete copy of any notice of
default or breach and all other communications respecting a default or breach,
alleged default or breach, failure of performance, or other condition that with
lapse of time or after additional notice, or both, could become a default or
breach by Assignor of or under the Management Agreement, or otherwise relating
to Assignor's good standing with respect to the Management Agreement.

         7.      Neither Assignee nor the Lenders, by accepting this
Assignment, shall be subject to any obligation or liability under the
Management Agreement, including, without limitation, any duty to perform any of
the covenants, conditions, provisions or agreements made by Assignor, but all
such obligations and liabilities shall continue to rest upon Assignor as though
this Assignment had not been made.  Upon the occurrence of an Event of Default
or a default under the Management Agreement and the election of Assignee as
described in Paragraph 2 hereof, however, the performance by Assignee of the
covenants, conditions, obligations and agreements of Assignor under the
Management Agreement shall be a condition of the continued performance of
Management Company to Assignee.

         8.      Assignee and the Lenders shall have the right at any time to
appear in and defend and be represented by counsel of their own choice in any
action or proceeding purporting to affect Assignor's rights under the
Management Agreement.

         9.      Assignor shall indemnity and hold Assignee and the Lenders
harmless from any and all damages and losses arising as a result of or related
to the Management Agreement, this Assignment or the exercise by Assignee and
the Lenders of any of their rights under this Assignment, including, without
limitation, any judgment, amounts paid in settlement, and all costs and
expenses, including reasonable attorneys' fees, incurred in defending or
settling any action, suit or proceeding in connection with the foregoing.

         10.     All sums advanced or paid by Assignee or the Lenders under the
terms hereof, all amounts paid, suffered or incurred by Assignee or the Lenders
in exercising any authority granted herein, including reasonable attorneys'
fees, and all other amounts due Assignee or the Lenders from Assignor in
connection with this Assignment shall be added to the Obligation, shall be
secured by all deeds of trust and other lien and security documents securing
the Obligation, shall bear interest at the highest rate payable on any of the
Obligation until paid, and shall be due and payable by Assignor to Assignee (or
the Lenders, as the case may be) immediately without demand.

         11.     Neither the execution and delivery of this Assignment nor any
failure on the part of Management Company to comply with, honor and perform in
accordance with the Management Agreement shall affect the liability of any
party to pay and perform the Obligation.

         12.     The taking of this Assignment by Assignee shall not effect the
release of any other collateral now or hereafter held by Assignee as security
for the Obligation, nor shall the taking of additional security for the
Obligation hereafter effect a release or termination of this Assignment or any
terms, conditions or provisions hereof.

         13.     Assignor, upon request of Assignee, shall execute and deliver
such additional documents, including but not limited to financing statements,
and do such other acts as may be reasonably necessary to fully implement the
intent of this Assignment and to perfect and preserve the lights and interests
of Assignee hereunder and the priority thereof.

         14.     Time is of the essence hereof.  This Assignment shall be
binding upon Assignor and its successors and assigns and shall inure to the
benefit of Assignee and the Lenders and their successors and assigns; this
Assignment, however, is not intended to confer any right or remedies upon any
person other than the parties hereto and their successors and assigns.

         15.     Assignor shall pay all costs and expenses, including without
limitation costs of Uniform Commercial Code searches, court costs and
reasonable attorneys' fees, incurred by Assignee and the Lenders in exercising
the rights and remedies of Assignee and the Lenders hereunder.  In the event of
any court proceedings, court costs and attorneys' fees shall be set by the
court and not by jury and shall be included in any judgment obtained by
Assignee and the Lenders.

<PAGE>   245
         16.     No failure or delay on the part of Assignee or the Lenders in
exercising any right, power or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power, or
remedy hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy.  The rights, powers and remedies hereunder
are cumulative and may be exercised by Assignee and the Lenders either
independently of or concurrently with any other right, power or remedy
contained herein or in any document or instrument executed in connection with
the Obligation.

         17.     By executing this Assignment, Assignor acknowledges receipt of
a copy hereof.  A carbon, photographic or other reproduced copy of this
Assignment and/or any financing statement relating hereto shall be sufficient
for filing and/or recording as a financing statement.  This Assignment shall be
governed by and construed according to the laws of the State of Arizona.

                 3.       Except as stated in the responses contained in the

<PAGE>   255
information disclosed in the "ENVIRONMENTAL QUESTIONNAIRE AND DISCLOSURE

Release or presence of, any Hazardous Substance on the Property in excess of
the reportable quantities prescribed by CERCLA or applicable state law, or the

or in the vicinity of the Property.  Borrower's intended future use of the
Property will not result in the Release of any Hazardous Substance on the
Property.

                 7.       Indemnitor shall give prompt written notice to the
Administrative Agent under, and at the address set forth in, the loan agreement

                 investigation or settlement by or with any federal, state or
                 local governmental authority (including, without limitation,
                 any applicable state agency or the U.S. Environmental
                 Protection Agency) with respect to the presence of any
                 Hazardous Substance on the Property or the migration thereof
                 from or to any other property adjacent to, or in the vicinity
                 of, the Property;

                          (b)     All claims made or threatened by any third
                 party against Indemnitor or the Property relating to any loss
                 or injury resulting from any Hazardous Substance;

                          (c)     Indemnitor's discovery of any occurrence or
                 condition on any property adjoining or in the vicinity of the
                 Property that could cause the Property or any part thereof to
                 be subject to any restrictions on its ownership, occupancy,
                 transferability or use under any Environmental Laws; and

                          (d)     Indemnitor's discovery of a violation of
                 Environmental Laws that Indemnitor is legally required to
                 report to any federal, state or local governmental authority
                 or the discovery of a Release of a Hazardous Substance in
                 sufficient quantities to be reportable under CERCLA or
                 applicable state law to any federal, state or local

                 8.       Indemnitor shall conduct and complete all
investigations, studies, sampling, testing and all remedial, removal, and other
actions necessary to clean up and remove all Hazardous Substances in, from or
affecting the Property:

                          (a)     In accordance with all applicable
                 Environmental Laws;

                          (b)     To the satisfaction of the Lenders; and

                          (c)     In accordance with the orders and directives
                 of all governmental authorities.

                 9.       Indemnitor shall, within thirty (30) days after
demand by Administrative Agent, provide Administrative Agent with a bond,
letter of credit, or similar financial assurance evidencing to Administrative
Agent's satisfaction that sufficient funds are available to pay the cost of
complying with the requirements of Paragraph 8 above.

                 10.      If Administrative Agent shall ever have reason to
believe that there are Hazardous Substances (other than those described in the
"ENVIRONMENTAL QUESTIONNAIRE AND DISCLOSURE STATEMENT") affecting any of the
Property, Administrative Agent (by its officers, employees, and agents) at any
time and from time to time may contract for the services of persons (the "SITE
REVIEWERS") to perform environmental site assessments ("SITE ASSESSMENTS") on
the Property for the purpose of determining whether there exists on the
Property any environmental condition that could result in any liability, cost,
or expense to the owner, occupier, or operator of such Property arising under
any Environmental Laws.  The Site Assessments may be performed at any time or
times, upon reasonable notice, and under reasonable conditions established by
Indemnitor that do not impede the performance of the Site Assessments.  The
Site Reviewers are hereby authorized to enter upon the Property for such
purposes.  The Site Reviewers are further authorized to perform both above and
below the ground testing for environmental damage or the presence of Hazardous
Substances on the Property and such other tests on the Property as may be
necessary to conduct the Site Assessments in the reasonable opinion of the Site
Reviewers.  Indemnitor will supply to the Site Reviewers such historical and
operational information regarding the Property as may be reasonably requested
by the Site Reviewers to facilitate the Site Assessments and will make
available for meetings with the Site Reviewers appropriate personnel having
knowledge of such matters.  On request, Administrative Agent shall make the
results of such Site Assessments fully available to Indemnitor, which (prior to
an Event of Default under the Loan documents) may, at its election, participate
under reasonable procedures in the direction of such Site Assessments and the
description of tasks of the Site Reviewers.  The cost of performing such Site
Assessments shall be paid by Indemnitor upon demand of Administrative Agent.

                 11.      Administrative Agent shall have the right, but not
the obligation, without in any way limiting Administrative Agent's other rights
and remedies under the Loan documents, to enter onto the Property or to take
such other actions as it deems necessary or advisable to clean up, remove,
resolve, or minimize the impact of, or otherwise deal with, any Hazardous
Substances





                                      -4-
<PAGE>   257
on or affecting the Property following receipt of any notice from any person or
entity asserting the existence of any Hazardous Substances pertaining to the
Property or any part thereof that, if true, could result in an order, notice,
suit, imposition of a lien on the Property, or other action and/or that, in
Administrative Agent's sole opinion, could jeopardize Administrative Agent's or
the Lenders' security under the Loan documents.  All reasonable costs and
expenses paid or incurred by Administrative Agent in the exercise of any such
rights shall be secured by the Loan documents and shall be payable by
Indemnitor upon demand.

                 12.      Administrative Agent and the Lenders shall have the
right at any time to appear in and to participate in, as parties if they so
elect, and be represented by counsel of their own choice in, any action or
proceeding initiated in connection with any Environmental Law that affects the
Property.

                 13.      Indemnitor shall indemnify and hold harmless the
Lenders and Administrative Agent, the initial successor to their interest in
the Property, the initial purchaser of the Property upon foreclosure of the
Lenders' interest in the Property, and all directors, officers, employees and
agents of all of the foregoing, from and against all claims, costs, expenses,
actions, suits, proceedings, losses, damages and liabilities of any kind
whatsoever, including but not limited to attorney's fees and expenses, directly
or indirectly arising out of or attributable to (i) the use, generation,
manufacture, production, storage, Release, threatened Release, or presence of a
Hazardous Substance on, under or about the Property; (ii) any violation or
claim of violation of any Environmental Law with respect to the Property; or
(iii) any breach of any of the warranties, representations and covenants
contained herein.

                 14.      This Environmental Indemnity Agreement shall be
binding upon Indemnitor and its successors and assigns and shall inure to the
benefit of the Lenders and Administrative Agent and their successors and
assigns.  The indemnity contained herein shall continue in full force and
effect and shall survive the payment and performance of the Loan, the release
of any lien or encumbrance securing the Loan, any foreclosure (or action in
lieu of foreclosure) of any lien or encumbrance securing the Loan, the exercise
by the Lenders and Administrative Agent of any other remedy under any documents
securing the Loan, and any suit, proceeding or judgment against Indemnitor by
Administrative Agent or the Lenders hereon; provided that the Lenders and
Administrative Agent agree that Indemnitor shall not be liable for any claims,
costs, expenses, losses, damages and liabilities (i) that arise after the
transfer (the "Transfer") of the Property to the Administrative Agent or the
Lenders or to the initial purchaser of the Property upon foreclosure of the
Lenders' interest in the Property, and (ii) that were caused solely by the
actions of the Administrative Agent or the Lenders, any successor to their
interest in the Property or said initial purchaser after the Transfer; and
provided further that the Lenders and Administrative Agent agree that
Indemnitor's indemnity obligation contained herein shall expire on the second
anniversary after the Loan shall have been paid in full; satisfaction of the
Loan in connection with a foreclosure sale shall not constitute a repayment of
the Loan for the purpose of terminating Indemnitor's indemnity obligation
hereunder.

                 15.      The indemnity contained herein shall not be subject
to any nonrecourse or other limitation of liability provisions contained in any
document or instrument executed and delivered in connection with the Loan and
the liability of Indemnitor hereunder shall not be limited by any such
nonrecourse or similar limitation of liability provisions.

                 16.      If any material warranty, representation or statement
contained herein shall be or shall prove to have been false when made or if
Indemnitor shall fail or neglect to perform or observe any of the terms,
provisions or covenants contained herein, the same shall constitute an Event of
Default under the Loan and under all documents and instruments executed and
delivered in connection therewith that shall entitle Administrative Agent and
the Lenders to pursue any and all remedies provided for such default.

                 17.      Any notice required or permitted in connection
herewith shall be given in the manner provided in any loan agreement or other
documents executed and delivered in connection with the Loan.

                 18.      Indemnitor acknowledges that the Lenders and
Administrative Agent have and will rely upon the representations, warranties
and agreements herein set forth in closing and funding (or modifying as the
case may be) the Loan and that the execution and delivery of this Environmental
Indemnity Agreement is an essential condition but for which the Lenders and
Administrative Agent would not close or fund (or modify) the Loan.

                 19.      Indemnitor waives any right or claim of right to
cause a marshalling of the assets of Indemnitor or to cause the Lenders and
Administrative Agent to proceed against any of the security for the Loan before
proceeding under this Environmental Indemnity Agreement against Indemnitor;
Indemnitor agrees that any payments required to be made hereunder shall become
due on demand; Indemnitor expressly waives and relinquishes all rights and
remedies accorded by applicable law to indemnitors or guarantors (including,
without limitation, A.R.S. Sections 12-1641, et seq.), except any rights of
subrogation that Indemnitor may have, provided that the Indemnity provided for
hereunder shall neither be contingent upon the existence of any such rights of
subrogation nor subject to any claims or defenses whatsoever that may be
asserted in connection with the enforcement or attempted enforcement of such
subrogation rights, including, without limitation, any claim that such
subrogation rights were abrogated by any acts or omissions of the Lenders or
Administrative Agent.

                 20.      This Environmental Indemnity Agreement shall be
governed by and construed according to the laws of the State of Arizona except
as otherwise provided herein.
