                ---------------------------------------
provision is hereby added to the Credit Agreement:

     6.8. Acquisition of Newly-Constructed Hotels.  (a) Neither Sunstone nor
          ---------------------------------------                           
     the Borrower nor any of their respective Subsidiaries shall consummate
     (whether or not contractually obligated to do so) the acquisition of a
     newly-constructed Hotel unless (i) taking into account all Indebtedness of
     Sunstone as of the date of such acquisition (including without limitation
     any Indebtedness incurred, directly or indirectly, to finance such
     acquisition in whole or in part), Sunstone shall be in compliance with the
     provisions of Sections 6.4, 6.5 and 6.6 upon the consummation of such
     acquisition and (ii) the Borrower shall furnish to the Administrative Agent
     prior to such acquisition a certificate of the chief financial officer of
     Sunstone (together with such supporting documentation as the Administrative
     Agent shall require) with respect to such compliance, all in form and
     substance satisfactory to the Administrative Agent.  For purposes of
     establishing such compliance with the provisions of Sections 6.4, 6.5 and
     6.6 as of the date of acquisition of such Hotel, all determinations shall
     be made on the basis of the financial statements as at the end of the most
     recent Fiscal Quarter preceding the date of such acquisition, except that
     (A) Total Indebtedness (in the case of Section 6.4), Total Secured Recourse
     Indebtedness (in the case of Section 6.5) and Non-Recourse Indebtedness (in
     the case of Section 6.6) shall each be determined as of the date of
     acquisition of such Hotel and (B) all Hotels (but only those Hotels) owned
     by the Borrower and its Subsidiaries as of the date of acquisition of such
     Hotel (and including such Hotel) shall be included for purposes of
     determining such compliance.  In the event that, as of the date of
     acquisition of such Hotel, the financial statements for the most recent
     Fiscal Quarter are not yet available, the certificate required to be
     delivered under clause (ii) above shall be prepared on the basis of
     reasonable estimates by the Borrower's management of the applicable
     financial information as at the end of such most recent Fiscal Quarter, and
     such certificate shall then be promptly updated when the financial
     statements for such Fiscal Quarter are available.

          (b)   Not later than thirty (30) days after the date on which the
     Borrower, Sunstone or any of their respective Subsidiaries enter into a
     contract to acquire a Hotel to be constructed or under construction, the
     Borrower shall provide the Administrative Agent with a copy of such
     contract, along with a general description of such Hotel (including
     location and number of rooms).

          8.    Financial Statements.  Section 7.11(g) is hereby modified by
                --------------------

days."

          9.    Year 2000 Covenant.  The following provision is hereby added to
                ------------------

                                       4

 
          7.25  Year 2000 Covenant.  The Borrower shall ensure that Sunstone,
                ------------------                                           
     the Borrower and each of their Subsidiaries are Year 2000 Compliant in a
     timely manner, but in no event later than October 1, 1999.  The Borrower
     shall use its best efforts to cause the Operating Lessee, the Manager and
     each of the Hotels owned by Sunstone, the Borrower or any of their
     Subsidiaries to be Year 2000 Compliant in a timely manner and shall cause
     each of the foregoing to be Year 2000 Compliant not later than December 31,
     1999 if the failure to be Year 2000 Compliant could have a Material Adverse
     Effect.  The Borrower shall, or shall cause the Operating Lessee or Manager
     to, make reasonable inquiries of all major contractors of the Borrower,
     Sunstone, their Subsidiaries, the Hotels, the Operating Lessee and the
     Manager to confirm that such major contractors are, or will be no later
     than December 31, 1999, Year 2000 Compliant and will request from such
     major contractors reasonable verification thereof.  For purposes of this
     section, "major contractors" means those Persons who make payments, or
     furnish goods or services, to the Borrower, Sunstone, any of their
     Subsidiaries, any of the Hotels, the Operating Lessee or the Manager, the
     failure of which Persons to be Year 2000 Compliant could have a Material
     Adverse Effect.  In furtherance of this covenant, the Borrower shall, in
     addition to any other necessary actions, perform or cause to be performed a
     comprehensive review and assessment of all software, hardware, equipment,
     goods and systems utilized or material to the physical operations, business
     operations or financing reporting of the Borrower, Sunstone, their
     Subsidiaries, the Hotels, the Operating Lessee and the Manager, and shall
     adopt or cause to be adopted a detailed plan for the testing, remediation
     and monitoring of such software, hardware, equipment, goods and systems to
     ensure compliance with the foregoing provisions.  The Borrower shall,
     within thirty (30) days of the Administrative Agent's written request,
     provide to the Administrative Agent such certification or other evidence of
     the Borrower's compliance with the provisions of this section as the
     Administrative Agent may from time to time reasonably require.

     Hotel Value and (ii) $50,000,000, (b) engage in the renovation of
     (including construction of additions to) any Hotels with respect to which
     the cost to complete the same shall at any time exceed in the aggregate the
     lesser of (i) fifteen percent (15%) of Total Hotel Value and (ii)
     $100,000,000, or (in the aggregate with costs described in clause (a)) the

     consideration payable therefor shall at any time exceed in the aggregate
     the lesser of (i) fifteen percent (15%) of Total Hotel Value and (ii)
     $120,000,000 (without regard to whether the payment thereof is a recourse
     obligation of Sunstone, the Borrower or any of their respective
     Subsidiaries), or (d) engage in the development or construction of Hotels
     (without regard to whether the same is permitted under clauses (a), (b) or
     (c) above) or enter into any agreements to purchase Hotels (whether under
     construction, to be constructed or otherwise) or other assets, unless
     Sunstone, the Borrower or such Subsidiary (as applicable) at all times has
     available sources of capital equal to the total cost to complete such
     development or construction and to pay in full the cost of the purchase of
     such Hotels or other assets (to the extent that the payment of such cost of
     purchase constitutes a recourse obligation of Sunstone, the Borrower or its
     Subsidiary), which available sources of capital may include the Available
     Credit to the extent that the Borrower may borrow the same for the purposes
     required.

          11.   Pricing.  Notwithstanding anything to the contrary set forth in
                -------

the extent that all financial information necessary to deliver such financial
statements and Compliance Certificate is not then available, Borrower may
satisfy the requirements of this paragraph by delivering financial statements
and information in sufficient detail to determine the Leverage Ratio at the end
of such Fiscal Quarter.  Notwithstanding anything to the contrary contained in
the Credit Agreement, the Funding Date shall be the Pricing Date with respect to
the determination of Status based on the Leverage Ratio for the Fiscal Quarter
ending June 30, 1998, Status shall be determined on such date and such Status
shall remain in effect until a change in Status thereafter occurs.  The
provisions of this paragraph shall not relieve the Borrower of any of its
obligations under Section 7.11 of the Credit Agreement and shall not affect any
Pricing Date or any determination of Status except as expressly set forth
herein.

          12.   Closing Deliveries.  Prior to or simultaneously with the
