shall remain outstanding as USRP Common Stock and shall not be converted into
any other security pursuant to the Merger.  The certificates for such shares
shall not be surrendered or in any way modified by reason of the effectiveness
of the Merger.

          (b)  Each share of QSV common stock, par value $0.01 per share (the
"QSV Common Stock"), owned by the Stockholders shall be automatically converted
without any action on the part of such holders into the right to receive (i)
4,088 shares of USRP Common Stock, (ii) cash in an amount equal to $11.80 per
share of USRP Common Stock that would otherwise be issued in the Merger or (iii)
any combination of USRP Common Stock and cash with a total value equal to the
value of 4,088 shares of USRP Common Stock based on a value of $11.80 per share
(the "Merger Consideration"); provided, however, the cash portion of the Merger

counsel to USRP, is necessary to enable USRP to continue to qualify as a REIT;
and provided further, however, that the number of shares of USRP Common Stock
issuable to the Stockholders hereunder shall be reduced by the number of shares

          (c)  Each right to receive Contingent Shares under the Withdrawal
Agreement and OP Unit held by QSV (as set forth on Schedule 3.8) shall be

terminated.

          (d)  Notwithstanding anything to the contrary contained in this
Agreement, no Stockholder has the right to have his QSV Common Stock converted
into USRP Common Stock and no Stockholder has the right to have USRP Common
Stock issued to such Stockholder if such conversion or issuance (or the right to
such conversion or issuance) would, in the opinion of counsel to USRP, cause
USRP to own (directly or constructively through the application of Section 318
of the Code, as modified by Section 856(d)(5) of the Code) an interest in a
tenant that is described in Section 856(d)(2)(B) of the Code and accordingly
cause USRP to receive or accrue rental income that fails to constitute "rents
from real property" within the meaning of Sections 856(c)(2)(C) or 856(c)(3)(A)
of the Code and (i) any attempt to effect such conversion or issuance in the
case of the existence of such an opinion shall be null and void and shall have
no effect for any purpose and (ii) that portion of any document or instrument
indicating that such conversion or issuance may be made will have no force or
effect.

fees and reasonable third-party expenses of investigating, defending or
prosecuting litigation (collectively, the "Damages") suffered by the Indemnified
Parties, arising from or by reason of the breach by or any inaccuracy of any
warranty, representation or covenant made by the Indemnifying Party.
Indemnification pursuant to this Section 9.1 shall be the sole and exclusive
remedy for any breach of this Agreement by any parties hereto.

     9.2. Nature and Survival of Representations, Warranties and Indemnities.
          ------------------------------------------------------------------
Unless otherwise provided in this Agreement, all representations, warranties,
covenants and agreements made by the parties hereto in this Agreement or in the
documents and instruments delivered pursuant hereto or in connection herewith
shall survive the Closing, the delivery of any instrument of conveyance, and the
Merger and shall remain effective and enforceable for a period of one year from
the Closing Date. Any claim for indemnification asserted in writing before the
expiration of the survival period, including any rights to contribution pursuant
to Section 9.5, shall survive until resolved or determined by arbitration or
barred by the applicable statute of limitations.

     9.3. Assumption of Defense.  If any action or claim shall be brought or
          ---------------------
asserted against an Indemnified Party in respect of which indemnity may be
sought from an Indemnifying Party, the Indemnified Party shall promptly notify
the Indemnifying Party in writing (but the omission to notify the Indemnifying
Party shall not release such person from any liability which it may have to the
Indemnified Party, except to the extent that such failure materially prejudices
the rights of the Indemnifying Party) and the Indemnifying Party shall assume
the defense thereof and the payment of all reasonable third party expenses
arising therefrom. The legal counsel selected by the Indemnifying Party shall be
subject to the consent of the Indemnified Party, which consent shall not be
unreasonably withheld or delayed. The Indemnified Party shall have the right to
employ separate counsel in any such action and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party, unless (a) the employment thereof has been specifically
authorized in writing by the Indemnifying Party; (b) the Indemnifying Party has
failed to assume the defense and employ counsel; or (c) the named parties to
such action include both the Indemnifying Party and the Indemnified Party, and
the Indemnified Party shall have been advised in good faith by its counsel that
the representation of the Indemnifying Party and the Indemnified Party by the
same counsel may be inappropriate due to actual or potential differing interests
between them, in which case the fees of counsel for the Indemnified Party shall
be paid by the Indemnifying Party. In such events, the Indemnifying Party shall
not have the right to assume the defense of such action on behalf of the
Indemnified Party. The Indemnifying Party shall not, in connection with any one
such action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expense of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
by the Indemnified Party in writing. The

                                       18
<PAGE>

Indemnifying Party shall not be liable for any settlement of any such action
effected without its written consent, but if any such action is settled with the
Indemnifying Party's written consent, or if there shall be a final judgment for
the plaintiff in any such action, the Indemnifying Party shall indemnify and
hold harmless the Indemnified Party from and against any loss or liability by
reason of such settlement or judgment.

     9.4. Cooperation.  In any event involving a claim of any third party, the
          -----------
Indemnified Party and the Indemnifying Party shall cooperate fully with each
other in the defense of any such claim under this Article IX. Without limiting
the generality of the foregoing, the Indemnified Party shall furnish the
Indemnifying Party with such documentation or other evidence as is then in its
possession as may reasonably be requested by the Indemnifying Party for the
purpose of defending against any such claim.

     9.5. Contribution.  After the Closing of the Merger, no Stockholder shall
          ------------
be entitled to seek contribution from QSV in respect of any liability resulting
from the breach of any representation, warranty or covenant made by QSV or the
Stockholder in this Agreement. Each Stockholder shall contribute to the amount
paid or payable pursuant to this Article IX by the Stockholders as a result of
any claim, damage, loss, liability or expense for which the Stockholders are
jointly liable in such proportion as is appropriate to reflect (i) the relative
benefits received by each Stockholder, (ii) the relative fault of each
Stockholder, (iii) the relative ability of each Stockholder to have prevented
the breach and (iv) any relevant equitable considerations. The relative fault of
each Stockholder shall be determined by reference to, among other things, the
Stockholders' relative intent, actual knowledge, access to information and
opportunity to correct or prevent the alleged act or omission giving rise to
such loss, claim, damage, liability or expense. The Stockholders agree that it
would not be just and equitable if contribution were determined without
reference to the equitable considerations referred to above. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities or expense (or actions in respect thereof) referred to above shall
be deemed to include any legal or other expenses incurred by such indemnified
party in connection with investigating or defending any such claim.

                                  ARTICLE X.

                                 MISCELLANEOUS

     10.1.  Expenses.  Each of the parties hereto shall pay the fees and
            --------
expenses of its own counsel, accountants or other experts, and all expenses
incurred by such party incident to the negotiation, preparation, execution,
consummation and performance of this Agreement and the transactions contemplated
hereby. Notwithstanding the foregoing, upon the closing under the REIT Stock
Purchase Agreement, USRP shall pay cash in an amount equal to $60,000 to
Christopher Weil & Company, Inc. as a result of the consummation of the
transactions contemplated thereby.

     10.2.  Arbitration.  Any controversy or claim arising out of or relating to
            -----------
this Agreement, the Transaction Documents, and the transactions contemplated
herein or therein, or the breach thereof, shall be settled by arbitration
administered by the American Arbitration Association in accordance with its
Commercial Arbitration Rules, and judgment on the award rendered by the
arbitrator may be entered in any court having jurisdiction thereof. The
arbitration shall be conducted under the Emergency Interim Relief Procedures of
the AAA Commercial Arbitration

                                       19
<PAGE>

Rules. The arbitration tribunal shall be composed of a single arbitrator, to be
appointed pursuant to AAA rules and Emergency Interim Relief Procedures. The
Optional Rules for Large, Complex Commercial Disputes shall not apply. Pursuant
to Rule E-8, the arbitration hearing shall be conducted in Dallas, Texas, within
30 days after confirmation of the arbitrator's appointment. The arbitrator shall
not have the authority to award punitive damages.

     10.3.  Notices.  Any notice necessary under this Agreement shall be in
            -------
writing and shall be considered delivered three (3) days after the mailing is
sent certified mail, return receipt requested, or when received, if sent by
telecopy, prepaid courier, express mail or personal delivery to the following
addresses:

          If to USRP:         U.S. Restaurant Properties, Inc.
                              12240 Inwood Road, Suite 200
                              Dallas, Texas 75244
                              Attention:  Chief Executive Officer
                              Facsimile:  (972) 233-6453

          If to the Stockholders:  At the addresses set forth below their
signature on the signature pages hereto.

     10.4. Waiver.  No amendment or waiver of any provision of this Agreement,
           ------
nor consent to any departure therefrom, shall be effective unless the same shall
be in writing and signed by an officer of each party hereto, and then such
waiver or consent shall be effective only in a specific instance and for the
specific purpose for which given. No failure on the part of a party hereto to
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder
preclude any other or further exercise thereof or the exercise of any other
right. The remedies provided in this Agreement are cumulative and not exclusive
of any remedies provided by law.

     10.5. Prior Agreements Superseded.  This Agreement and the documents
           ---------------------------
executed in connection herewith at the Closing constitute the entire agreement
between the parties with respect to the subject matter hereof and supersede any
and all prior written or oral agreements and understandings with respect to the
matters covered hereby, including the Withdrawal Agreement.

     10.6. Binding Effect.  This Agreement shall be binding upon and inure to
           --------------
the benefit of the parties hereto and their respective successors and assigns.

     10.7. Governing Law.  THIS AGREEMENT, AND THE RIGHTS AND OBLIGATIONS OF
           -------------
THE PARTIES HERETO, SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF TEXAS, WITHOUT
REGARD TO ITS PRINCIPLES OF CONFLICT OF LAWS.

     10.8. Headings; Interpretation.  The headings used in this Agreement have
           ------------------------
been inserted for convenience only and do not constitute matters to be construed
or interpreted in connection with this Agreement. Unless the context of this
Agreement otherwise requires, (a) words using the singular or plural number
shall also include the plural or singular number, respectively; and (b) the

                                       20
<PAGE>

terms "hereof," "herein," "hereby," "hereto" and derivative or similar words
shall refer to this entire Agreement.

     10.9.  Attorneys' Fees.  The prevailing party in any legal or arbitration
            ---------------
proceedings brought by or against the other party to enforce any provision of
this Agreement, as determined by the arbiter of such dispute, shall be entitled
to recover against the non-prevailing party the reasonable attorneys' fees,
court or arbitration costs and other expenses incurred by the prevailing party.

     10.10. Counterparts.  This Agreement may be executed in two or more
            ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     10.11. Severability and Reformation.  If any provision of this Agreement
            ----------------------------
is held to be illegal, invalid or unenforceable under any current or future law,
and if the rights or obligations of the parties under this Agreement would not
be materially and adversely affected thereby, such provision shall be fully
separable, and this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part thereof,
and the remaining provisions of this Agreement shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance therefrom. In lieu of such illegal, invalid or
unenforceable provision, there shall be added automatically as a part of this
Agreement, a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible, and the parties
hereto request the court or any arbitrator to whom disputes relating to this
Agreement are submitted to reform the otherwise illegal, invalid or
unenforceable provision in accordance with this Section 10.11.

     10.12. Third Parties.  Except for the rights of indemnified parties under
            -------------
Section 9.1 hereof, nothing expressed or implied in this Agreement is intended,
or shall be construed, to confer upon or give any person or entity other than
QSV, USRP and the Stockholders (or their successors, heirs, representatives and
permitted assigns) any rights or remedies under or by reason of this Agreement.

     10.13. Announcements.  The parties hereto agree that all public
            -------------
announcements relating to the Merger will be made only as mutually agreed upon;
provided, however, that either party may make any public announcements as may be
required by law without the approval of the other party.

     Prior to the Closing Date, the Board of Directors of USRP, or a committee

into that certain Agreement and Plan of Merger dated as of December 29, 2000
(the "Merger Agreement");

     WHEREAS, pursuant to the terms of the Merger Agreement, QSV shall be merged
with and into the Corporation (the "Merger"), and the Stockholders shall
exchange their shares of QSV common stock in whole or part for common stock of
the Corporation, par value $.001 per share ("Common Stock");

     WHEREAS, each of the Stockholders is currently serving as a director of the
Corporation; and

     NOW THEREFORE, BE IT RESOLVED, that subject to the occurrence of the
Merger, the acquisition by each Stockholder of that number of shares of Common
Stock set forth opposite such Stockholder's name set forth below pursuant to the
terms and conditions of the Merger Agreement is hereby approved and authorized
