           ---------------------
election under Section 14.7, and as contemplated thereby, the Seller hereby
joins in the Original Agreement for the purposes stated herein, and the parties
hereto hereby amend the Original Agreement in the manner described below.
Except as amended hereby or as otherwise specified herein, the Original
Agreement remains in full force and effect.

                     Purchase of Interests; Purchase Price
                     -------------------------------------

     2.1   Purchase of Interests.  In lieu of purchasing the Property from the
           ---------------------
Company, the Purchaser agrees to purchase and assume from the Seller, and the
Seller agrees to sell and convey to the Purchaser, all of the Seller's equity
member interests in the Company (the "Interests").

     2.2   Purchase Price. The purchase price for the Interests (the "Purchase
           --------------
Price") shall be the amount by which (a) ONE HUNDRED NINETEEN MILLION DOLLARS
($119,000,000.00) (as adjusted pursuant to Article 13 below) exceeds (b) the
principal balance on the Closing Date of the Existing Debt.  The Purchase Price
(as increased or decreased by the net amount of the adjustments described in

of the Original Agreement), shall be paid to the Seller in cash on the Closing
Date by wire transfer of immediately available funds to the Escrow Agent.

     2.3   Deposit.  The terms of the escrow pursuant to which the Deposits are
           -------
held shall be modified to provide that they are held for the benefit of the
Purchaser and the Seller, not the Purchaser and the Company.  All rights of the
Company in and to the Deposits remaining in escrow are hereby assigned to the
Seller.  To the extent the amount of the Initial Deposit of $1,000,000 that was
fully earned by the Company has not been distributed by the Company to the
Seller as a dividend or similar distribution, it will be distributed by the
Company to the Seller on or prior to the Closing Date and credited against the
Purchase Price.

              Seller's Representations, Warranties and Covenants
              --------------------------------------------------

     In order to induce the Purchaser to enter into this Agreement and to

           -------------

     (a)   The Seller represents and warrants that it is a limited partnership
duly organized, validly existing and in good standing under the laws of the
State of Delaware, is authorized to conduct the business in which it is now
engaged, and is duly qualified and in good standing in Delaware and in all
states where the ownership of its assets or the conduct of its business makes
such qualification necessary.

     (b)   The Company represents and warrants that it is a limited liability
company duly organized, validly existing and in good standing under the laws of
the State of Delaware, is authorized to conduct the business in which it is now
engaged, and is duly qualified and in good standing in Delaware and in all
states where the ownership of its assets or the conduct of its business makes
such qualification necessary.

     3.2   Title to Interests.  The Seller represents and warrants that the
           ------------------
Seller is the sole equity member of the Company, and Crestline Res III
Corporation ("Res III") is the sole non-equity member of the Company. The Seller
represents and warrants that no other person or entity holds any ownership
interest in the Company (including, in each case, any options, warrants or other
rights by which any person may acquire any such ownership interests). The Seller
represents and warrants further that (x) the Interests are, and shall at Closing
be transferred, free and clear of any and all Encumbrances, except for
restrictions set forth in the certificate of formation or the limited liability
company operating agreement (the "Organizational Documents") of the Company, as
in effect on the date of this Agreement. However, such Interests are and shall
be transferred subject to (i) the terms of the Organizational Documents and (ii)
the restrictions set forth in the Loan Agreement and the other Loan Documents
(as defined in the Loan Agreement), to the extent copies thereof have been
provided to the Purchaser (the "Other Loan Documents"). The Seller represents
and warrants that, subject to clauses (i) and (ii) of the preceding sentence,
the Seller has the complete and unrestricted power and right to sell, assign,
transfer and deliver the Interests to the Purchaser, and there are no agreements
or understandings between the Seller, on the one hand, and any other person or
entity, on the other hand, with respect to the ownership, voting rights, sale or
disposition of the Interests other than those set forth in the Organizational
Documents or in the Loan Agreement and the Other Loan Documents (except the
terms of the provisions of the letter agreement dated August

                                       3
<PAGE>

19, 1999 between Crestline and Hospitality Properties Trust ("HPT") giving HPT a
right of first refusal in the event of a transfer of the general partnership
interest in the Seller, which right HPT has waived.)

     3.3   No Subsidiaries; No Agreements.  The Seller and the Company represent
           ------------------------------
and warrant that (x) the Company has no subsidiaries, owns no assets other than
the Property, and conducts no business other than as specifically permitted
pursuant to the Company's limited liability company operating agreement (the
"Company LLC Agreement"), a true and complete copy of which is attached hereto
as Exhibit A, (y) the Company and the Seller are in compliance in all material
   ---------
respects with the terms of the Company LLC Agreement, including but not limited
to Section 5.03 and Sections 10.1, 10.2 and 10.3 thereof and (z) there are no
existing agreements (and will not be any agreements prior to Closing) between
the Company and one or more of Seller, Res III, Crestline or any of its other
affiliates that are not set forth in the Organizational Documents or in the Loan
Agreement or the Other Loan Documents.

     3.4   Due Authorization.  The execution, delivery and performance of this
           -----------------
Agreement and the consummation of the transactions contemplated hereby have been
duly and validly authorized by all requisite limited partnership actions on the
part of the Seller and by all requisite limited liability company actions on the
part of the Company, none of which actions have been modified or rescinded, and
all of which actions are in full force and effect.  The Original Agreement, as
affected by this Agreement, and this Agreement, each constitutes a valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms.  This Agreement constitutes a valid and binding obligation of
the Seller, enforceable against the Seller in accordance with its terms.

     3.5   No Violations or Defaults.  To the knowledge of the Seller, neither
           -------------------------
the Seller nor the Company has made any distributions in violation of the terms
of the Loan Agreement or the Other Loan Documents or the Organizational
Documents.

     3.6   Litigation.  There are no actions, suits, arbitrations, governmental
           ----------
investigations or other proceedings pending or, to the knowledge of the Company
or the Seller, threatened against the Company or the Seller, or affecting the
Interests or the Property (or any material portion thereof) before any court or
governmental authority, an adverse determination of which might adversely affect
(a) the financial condition or operations of the Company or the Seller, (b) the
ability of the Company or the Seller to enter into or perform this Agreement,
(c) the Company's title to the Property (or any material portion thereof) or (d)
the Seller's title to the Interests.

     3.7   Representations in Original Agreement.  Nothing in this
           -------------------------------------

                                       4
<PAGE>

Agreement shall in any way affect or limit the effectiveness of any of the
representations and warranties made by the Company in the Original Agreement.
The acknowledgements, agreements, waivers and releases made by the Purchaser in
Section 3.15 of the Original Agreement run to the benefit of the Seller to the
same extent as if the Seller was specifically named as the "Seller" in that
section.

     3.8   Financial Information.  With respect to the financial information
           ---------------------
described in Section 3.16 of the Original Agreement, the Seller represents and
warrants that, to the knowledge of the Seller, all such information has been

consistently with past practices and fairly presents the results of operations
of the Inns for the periods represented thereby, and has been relied upon by the
Seller in the ordinary course of business of the ownership of the Interests.

     3.9   Solvency.   The Seller represents that it is not insolvent within the
           --------
meaning of the Bankruptcy Code, nor has such Seller ceased to pay its debts as
they become due, nor filed or taken any action to file a voluntary petition,
case or proceeding under any section or chapter of the Bankruptcy Code, or under
any similar law or statute of the United States or any state thereof, relating
to bankruptcy, insolvency, reorganization, winding up or composition or
adjustment of its debts; and no such petition, case or proceeding has been filed
against the Seller which has not been dismissed, vacated or stayed on appeal;
and the Seller has not been adjudicated as a bankrupt or insolvent or consented
to, nor filed an answer admitting or failing reasonably to contest an allegation
of bankruptcy or insolvency; the Seller has not sought, or consented to or
acquiesced in, the appointment of any receiver, trustee, liquidator or other
custodian of it or a material part of its assets, and has not made or taken any
action to make a general assignment for the benefit of creditors; nor has any
arrangement, attachment or execution been levied and or any tax lien or other
governmental or similar lien been filed, against it or any material part of its
properties, which has not been duly and fully discharged prior to the date
hereof.

     3.10  Employees.  The Seller has no employees.
           ---------

     3.11  Tax Matters.  (a) The Seller (and, as regards the Company, the
           -----------
Company) represents and warrants that no federal or other taxing authority
(collectively, the "Taxing Authority") has asserted in writing any tax
deficiency, lien, interest or penalty against the Company or the Seller, or
against the Interests or any of the Inns, in each case that has not been paid,
and there is no pending audit or inquiry from any Taxing Authority that might
reasonably be expected to result in a material tax deficiency, lien, interest,
penalty or other assessment against the Company, the Seller, the Interests or
any of the Inns, and to the knowledge of the Company and the Seller, no event
has occurred and no condition or circumstance exists that presents a material
risk that any tax deficiency, lien,

                                       5
<PAGE>

interest, penalty or other assessment will be imposed against such party, the
Interests or any of the Inns.

     (b)   The Company and the Seller each represents and warrants that such
party (or an affiliate of such party) has timely filed or caused to be timely
filed all material Tax Returns (as defined below) required to be filed by such
party, and such party has paid (or an affiliate thereof has paid on its behalf)
all Taxes required to be paid as shown on such returns and all such Tax Returns
were, when filed, complete and accurate in all material respects, except where
the failure to file such Tax Returns, the failure to pay such Taxes and the
failure of such Tax Returns to be complete and accurate in all material respects
could not be reasonably expected to have a Material Adverse Effect, and no
material deficiencies for any Taxes have been or are currently being proposed,
asserted or assessed in writing, or to such party's knowledge, threatened in
writing by any taxing authority against or with respect to such party.

As used herein, "Tax" or "Taxes" means any federal, state, local, or foreign

schedule or attachment thereto, and including any amendment thereof.

     3.12  Compliance with GAAP.  The Seller represents and warrants that,
           --------------------
except for liabilities and obligations set forth in the Financial Statements,
the Company has no liabilities or obligations of any nature (whether accrued,
absolute, contingent or otherwise), which are required by generally accepted
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto) and fairly presented, in
accordance with the applicable requirements of such generally accepted
accounting principles ("GAAP") to be set forth on a balance sheet of the Company
or in the notes thereto and which, individually or in the aggregate, would have
a material adverse effect on the business, properties, assets, financial
condition or results of operations of the Company, taken as a whole, or on the
ability of the Company to perform in all material respects its obligations under
the Original Agreement, as affected by this Agreement, or under the Management
Agreement (a "Material Adverse Effect"). Except as previously disclosed in
writing to the Purchaser, there has been no event or condition, following the
date of the most recent Financial Statements, in connection with the business,
operations or assets of the Company that, individually

                                       6
<PAGE>

or in the aggregate, would have a Material Adverse Effect (a "Material Adverse
Change").

     3.13  Corporate Documentation.  The Seller represents and warrants that (i)
           -----------------------
it has delivered copies of the Loan Agreement and all Loan Documents to the
Purchaser and (ii) the minute book of the Company (the "Minute Book"), as
delivered to the Purchaser at Closing, shall contain all of the executed
consents and minutes of the proceedings of the members and managers of the
Company to the extent related to the Company from the date of the formation of

(i.e. the General Manager, Chief Engineer, if any, and the Controller of such
Inn), of Larry K. Harvey, Senior Vice President and Controller of Crestline,
Tracy M. J. Colden, Senior Vice President and General Counsel of Crestline and
Phillip Borkowski, Director, Asset Management for Crestline (collectively the
"Seller Knowledge Individual").  Neither the actual, present knowledge of any
other individual or entity, nor the constructive knowledge of any Seller
Knowledge Individual or of any other individual or entity shall be imputed to
any Seller Knowledge Individual.

     3.15  Withdrawal of Non-Equity Member.  Simultaneously with the Closing,
           -------------------------------
the Company and the Seller shall cause Res III to withdraw as the non-equity
member of the Company so that it can be replaced by a non-equity member
established by the Purchaser or its affiliates.

     3.16  Prior Representations Unaffected.  The Company confirms that all
           --------------------------------
representations and warranties made by it in the Original Agreement are
unaffected by this Agreement and are true and correct as of the date made.

           -----------------
Original Agreement and this Agreement and the consummation of the transactions

                                    -------

to the transfer of the Interests and other matters contemplated hereby, but in
no event later than August 31, 2001, unless the Seller and the Purchaser
mutually agree on an alternative date or alternative location. If the Closing
does not occur for any reason

                                       8
<PAGE>

by August 31, 2001, the provisions of Sections 7.11, 8.7 and/or Article X of
this Agreement shall apply, as applicable. All of the Seller and the Purchaser's
deliveries, the cash payment of the Purchase Price and sufficient additional
cash necessary for the parties to pay the costs contemplated by Section 5.2

Closing shall be interdependent and are to be considered simultaneous, so that

transfer fee under the Loan Agreement, the Lender's attorneys' fees reasonably
related to obtaining the Lender's consent to the transfer of the Interests, to
the extent payable by the Borrower under the Loan Agreement, the costs and
expenses of the Lender's due diligence review, to the extent payable by the

amendments or modifications to the mortgages, UCC filings  or other loan
documents affecting the Property, including any applicable transfer, mortgage or
recording fees or taxes, but excluding the costs of the Seller's counsel, if

           -------------------------------
affect or limit the effectiveness of the covenants and agreements made by the
Company and the Purchaser in Article VI of the Original Agreement (except that

                                       9
<PAGE>

the purchase of the Interests in the Company, rather than the Property of the
Company, means that permits under Section 6.5 may no longer need to be
transferred, and such transfer shall not be a condition precedent to Closing
except to the extent legally necessary in connection with the transfer of the
Interests for the ongoing operation of the Inns), and the provisions of Article
VI remain in full force and effect (except that the Feasibility Period, the

other party and its affiliates, successors and assigns, from all claims, losses,
damages, liabilities, costs and expenses (including reasonable attorneys' fees
and other legal expenses and other charges) to the extent arising from any
failure of the assuming party to perform the obligation so assumed after the
