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

               (a)  Each of the Properties is currently covered by an owner's

of title insurance (i) dated the Closing Date, (ii) in the full amount of the

                       I.     a separate tax lot; and

                       J.     such other endorsements as the Acquirer shall
                              reasonably require after review of the survey,
                              title insurance commitment and Leases.

                                      -9-
<PAGE>

             (b)  The Sellers and the Owners shall promptly deliver to the
Acquirer a copy of the existing title insurance policies covering the
Properties. The Sellers and the Owners shall, at or prior to the Closing,
deliver or cause to be delivered such commercially reasonable affidavits,
certificates, information and customary instruments of indemnification, such as
lien indemnitees, as shall be reasonably required to induce the applicable Title
Company to issue the title insurance policies contemplated by this Section 2.3.

     .4   Survey.
          ------

             (a)  Prior to the Closing, the Acquirer, at its option and expense
(subject to inclusion in the Acquisition Expenses), may obtain a survey of each
Property, prepared by a land surveyor licensed to perform surveys in the state
in which such Property is located, that meets the "Minimum Standard Detail
Requirements for ALTA/ACSM Land Title Surveys" as adopted by the American Land
Title Association/American Society and American Congress on Surveying and
Mapping in 1997 (or equivalent in the state in which such Property is located)
(each, an "ALTA Compliant Survey") and is acceptable to the Acquirer.

             (b)  The Sellers and the Owners shall promptly deliver or cause to
be delivered to the Acquirer a copy of the surveys of the Properties currently
in their possession.

     .5   Access to Information; Environmental Audits.
          -------------------------------------------

             (a)  The Sellers and the Owners have delivered to the Acquirer, or
shall deliver not later than five (5) days following the Effective Date,
legible, true, correct and complete copies of the items set forth in Exhibit
                                                                     -------
2.5(a)(i).  At all times before the Closing, each Seller and Owner shall provide
---------
or cause to be provided to the Acquirer and its affiliates, their respective
agents, employees, consultants and representatives, with continuing and
reasonable access to all files, books, records and other materials in the
possession or control of the Sellers and the Owners, as the case may be,
relating to the Properties and to the operations, assets and liabilities of the
Owners (including, without limitation, the items set forth in Exhibit
                                                              -------
2.5(a)(ii)) and the right to examine, inspect and make copies of such materials
-----------
as appropriate; provided, however, that all documents delivered to the Acquirer
in original form before the Effective Date are subject to the letter agreement
dated June 22, 1999, between the Acquirer and MMR Holdings.

             (b)  At all times prior to Closing, each Seller and Owner shall
also provide or cause to be provided for such parties to have reasonable
physical access to the Properties for the purpose of conducting surveys,
architectural, engineering, geotechnical and environmental inspections and tests
(including sampling and invasive testing for the presence of Hazardous Materials
performed in connection with Phase I environmental audits and, if necessary and
with the prior written approval of the Sellers and the Owners (such approval not
to be unreasonably withheld), Phase II environmental audits), feasibility
studies and any other inspections, studies or tests reasonably required by them.
The applicable Owner shall contract

                                      -10-
<PAGE>

with and pay for in full (or the Sellers shall provide for payment in full prior
to Closing), Engineering Consulting Services, Ltd., or such other environmental
audit firm as may be designated by the Acquirer and reasonably agreed to by the
Sellers to perform any environmental audit pursuant to this Agreement. The
Acquirer may conduct a "walk-through" of tenant spaces upon reasonable and
appropriate notice to tenants and subject to the rights of tenants. In the
course of its investigations, the Acquirer may make inquiries to third parties
including, without limitation, contractors, property managers, parties to any
contracts relating to the Sellers, Owners and the Properties, if any, lenders,
tenants and municipal, local and other governmental officials and
representatives.

          (c)  The Acquirer hereby agrees to indemnify and hold the Owners
harmless from and against any loss, cost, liability or damage to persons or the
improvements at the Properties suffered or incurred by the Owners (other than
Acquisition Expenses) as a result of the entry on the Properties prior to the
Closing by the Acquirer or its employees or agents.

          (d)  The Acquisition Expenses shall be paid by Sellers as set forth in
this Agreement.

          (e)  In the event that the Sellers and the Owners have not timely
fulfilled their obligations pursuant to the first two (2) sentences of Section
2.5(a), then, with respect to each Property for which any such obligation has
been breached (it being agreed that any breach of an obligation to provide
information with respect to an Owner shall be deemed a breach of such obligation
with respect to each Property owned by such Owner) (each, an "Unreviewed
Property"), and without reducing the Adjusted Purchase Price (but by means of
delaying the delivery to Sellers of that portion of the Adjusted Purchase Price
allocated to such Property), (i) the Acquirer may (or, if any Yield Differential
would be payable as a result of interest accruing on the Mortgage Debt on a
long-term fixed-rate basis, shall) cause the Lender at Closing to place into an
escrow account (or such other account as may be acceptable to Lender) an amount
equal to the Allocated Mortgage Debt for such Unreviewed Property for the period
commencing on the Closing Date and expiring on the Unreviewed Property Yield
Differential Expiration Date (as hereinafter defined), (ii) the Adjusted
Purchase Price payable or to be paid at Closing shall be reduced by an amount
equal to the Adjusted Purchase Price allocated to such Unreviewed Property as
shown on the Rent Roll, and (iii) prior to Closing, the Sellers shall cause the
Owner of such Unreviewed Property to transfer such Unreviewed Property to Seller
or an Affiliate of Seller reasonably approved in writing by the Acquirer by
quitclaim deed, without any representation or warranty, such that the applicable
Owner shall be released from any and all liability related thereto.  With
respect to each Unreviewed Property, not later than the date (the "Extended
Study Period Expiration Date") that is sixteen (16) days after the date on which
the Acquirer receives legible copies of the title policy and/or commitment (and
the accompanying title exception documents), survey, leases, environmental
audit, building condition survey and appraisal for such Unreviewed Property in
the Owners' and Sellers' possession and other information to be received under
Exhibits 2.5(a)(i) or to which access is granted under Section 2.5(a)(ii)
------------------                                             ----------
(including, if a Phase I environmental audit for an

                                      -11-
<PAGE>

Unreviewed Property required or recommended the performance of a Phase II
environmental audit, and Acquirer elects to have performed a Phase II
environmental audit for such Unreviewed Property, the resulting Phase II
environmental audit), if at all, the Acquirer shall deliver to the Sellers a
Dissatisfaction Notice and the specific reasons therefor, after which such
Unreviewed Property shall be deemed a Disqualified Property and the disposition
of such Property shall be governed pursuant to Section 2.6. In the event that an
Unreviewed Property is not a Disqualified Property pursuant to this Section
2.5(e), then, at such time as the Lender releases from escrow (or such other
account as may have been acceptable to Lender) the Allocated Mortgage Debt for
such Unreviewed Property (the "Unreviewed Property Yield Differential Expiration
Date"), the parties shall proceed to Closing with respect to such Unreviewed
Property in accordance with the other provisions of this Agreement (including,
without limitation, Articles 6 and 8). During the period commencing on the
Closing Date and expiring on the Unreviewed Property Yield Differential
Expiration Date (upon which date the Yield Differential shall cease to accrue
with respect to such Unreviewed Property), the Sellers shall pay to the
Acquirer, not less often than monthly, the Yield Differential.

     .6   Investigation.  Notwithstanding any other provision of this Agreement,
          -------------
the Acquirer shall have a period (the "Study Period") expiring at the close of
business on the date that is twenty-one (21) days following the Effective Date
to perform such examinations, inspections, testing, studies and/or
investigations of the condition of the Properties as the Acquirer deems
necessary.  If, prior to the expiration of such Study Period, the Acquirer
shall, in its reasonable discretion, be dissatisfied with a material matter
adversely affecting title to any Property (it being agreed that a document that
prevents the use of the Property for uses conducted thereon immediately prior to
the Effective Date, a site control agreement, a restrictive covenant, and a
lease or purchase option each constitutes a matter affecting title to such
Property), the survey of any Property, the environmental condition of any
Property, or the condition of an improvement located on any Property (any such
matter being hereinafter referred to as a "Property Defect" and any Property
that is subject to a Property Defect being hereinafter referred to as a
"Disqualified Property") then, prior to the expiration of the Study Period, the
Acquirer shall so notify the Owners in writing (the "Dissatisfaction Notice") of
its dissatisfaction with such Property or Properties and the specific reasons
therefor.  With respect to each Dissatisfaction Notice, within five (5) days
after receipt thereof, the Owners may elect to (x) cure the Property Defect
disclosed in the Dissatisfaction Notice by delivering written notice to the
Acquirer of its intent to cure, and not less than five (5) Business Days prior
to Closing, cure such Property Defect to the Acquirer's reasonable satisfaction,
(y) cure the Property Defect (solely for the purposes of this Agreement and not
the applicable Sonic Lease) by causing (i) SAI, or (ii) SAI and the tenant under
the applicable Sonic Lease, to execute and deliver to the Acquirer a writing
reasonably acceptable to the Acquirer in form and content stating that, pursuant
to the terms of the applicable Sonic Lease, SAI or the tenant under the
applicable Sonic Lease, as applicable, will be responsible for remedying the
Property Defect set forth in such Dissatisfaction Notice, or (z) exclude the
Disqualified Property affected by the Property Defect from the transaction.  In
the event that a Disqualified Property is excluded

                                      -12-
<PAGE>

from the transaction, (1) the Adjusted Purchase Price shall be reduced by the
amount equal to the Adjusted Purchase Price allocated to such excluded
Disqualified Property, and (2) Sellers shall cause the Owner of such
Disqualified Property to transfer such Disqualified Property to another Person
by quitclaim deed on or before the Closing Date, without any representation or
warranty, such that the applicable Owner shall be released from any and all
liability related thereto. Notwithstanding the foregoing sentence to the
contrary, in the event a Property Defect constitutes a violation or, with the
giving of notice would constitute a violation of Environmental Law and, in the
Acquirer's reasonable judgment, the "worst case" scenario for the costs of
remediating such violation or potential violation of Environmental Law could
exceed Two Hundred Fifty Thousand Dollars ($250,000), and the Owners do not or
cannot elect clause (z) above, then the Acquirer may, at its option, exclude the
applicable Disqualified Property from the transaction. In the event a Property
is excluded by the Owners pursuant to clause (z) above or excluded by the
Acquirer pursuant to the foregoing sentence, then, without reducing the Adjusted
Purchase Price (but by means of delaying the delivery to Sellers of that portion
of the Adjusted Purchase Price allocated to such Property), the Acquirer may
(or, if any Yield Differential would be payable as a result of interest accruing
on the Mortgage Debt on a long-term fixed-rate basis, shall) cause the Lender at
Closing to place into an escrow account (or such other account as may have been
acceptable to Lender) an amount equal to the Allocated Mortgage Debt for such
excluded Disqualified Property for the period (the "Yield Differential Period")
commencing on the Closing Date and expiring on the Yield Differential Period
Expiration Date (as hereinafter defined), in which event the Sellers shall pay
to Acquirer, not less often than monthly, the Yield Differential. At such time
as (a)(1) SAI obtains title to a Substitute Property and the same is conveyed to
the Acquirer on terms and conditions mutually agreeable to SAI and the Acquirer,
or (2) with the Sellers' prior written consent the Acquirer elects to substitute
another property owned by it for such Disqualified Property and (b) the Lender
releases from escrow the Allocated Mortgage Debt for such Substitute Property
(the "Yield Differential Period Expiration Date"), the Yield Differential shall
cease to accrue with respect to such Property. In the event the Sellers (I)
elect not to cure the Property Defect disclosed in the Dissatisfaction Notice,
(II) fail to cure the same, (III) fail to cause SAI, the tenant under the
applicable Sonic Lease, or both, to acknowledge SAI's or such tenant's
responsibility (as more particularly set forth above) to cure the same, and (IV)
fail to exclude the Property or Properties affected by the Property Defect, the
Acquirer may, at its option, (A) waive such matters and proceed to Closing, or
(B) exclude such Disqualified Property and cause the Sellers (1) to use best
efforts to cause SAI to deliver a Substitute Property and, (2) in the interim,
to bear any Yield Differential. If the Acquirer shall not have provided a
Dissatisfaction Notice as to a Property, the Acquirer shall not be entitled to
assert a breach of any representation or warranty against Seller or Owner
pursuant to this Agreement for any matter disclosed herein or in the due
diligence materials provided pursuant to this Agreement (except as a result of
actions by the Sellers or the Owners, as the case may be, occurring after the
expiration of such Study Period) for such Property.

otherwise acquire any of the interests of MMR Holdings, MMR Viking or MMR
Tennessee or in any securities or obligations of any kind convertible into any

into account in determining the Adjusted Purchase Price, (B) any Mortgage Debt
or other mortgage debt to be repaid or assumed as of the Closing Date, and (C)

the Sellers, or (iii) which challenges or impairs the ability of any such Owner
to execute or

                                      -20-
<PAGE>

          (e)  Repair and Service Contracts.  There are no repair or service
               ----------------------------
contracts to which the Owners are a party.

          (f)  Leases and Rent Roll.  The documents constituting the Leases
               --------------------
(including, without limitation, all amendments, modifications, supplements,
renewals, extensions and guarantees in connection therewith) that are delivered
to the Acquirer pursuant to this Agreement are true, correct and complete, in
all material respects.  There are no leasing or other fees or commissions due,
nor will any become due, pursuant to the terms of any Lease or any renewal or
extension or expansion of any Lease, and no understanding or agreement with any
party exists as to payment of any leasing commissions or fees regarding future
leases or as to the procuring of tenants.  To the Owners' knowledge, except as
disclosed in the Leases, no tenants have asserted in writing that there are any
defenses or offsets to rent accruing before or after the Closing Date.  The
Owners have not received any notice of any default or breach on the part of the
landlord under any Lease, nor, to the Owners' knowledge, does there exist any
such default or breach on the part of the landlord.  To the Owners' knowledge,
all rental payments due under each Lease have been paid through the date hereof,
the Owners have not received any prepayment of rent for a period in excess of
thirty (30) days, and no condition or event exists which, with the giving of
notice or the passage of time, or both, would constitute a material default by
any tenant under any Lease.  The Owners have no notice that any of the
landlord's obligations to construct tenant improvements or reimburse the tenants
for tenant improvements under the Leases have not been paid and performed in
full, or any concessions from the landlord under the Leases have not been paid
and performed in full.  The Owners have no notice of any obligation, and have
received no demand from any tenant, to perform any capital improvements or to
provide funds for any tenant to perform capital improvements.  All such
improvements shall be completed without Liens and the costs of such improvements
shall be fully paid as of the Closing Date.  At Closing (I) each Lease with
respect to a Property (other than the Continuing Leases) will (A) be a Sonic
Lease within the meaning of the Sonic Agreement, and (B) be guaranteed by SAI,
and (II) each Continuing Lease will be guaranteed by the Person, if any,

statements of MMR Holdings as of March 31, 1999, for the quarter then ended,
delivered to the Acquirer and any updates thereof requested by Acquirer prior to
the Closing, are or will be true, correct and complete in all material respects.
Such financial statements shall fairly present, in all material respects, the
financial position of the Owners as of the dates thereof and the results of
operations for the periods then ended, subject to normal year-end audit
adjustments.  Except as set forth in the unaudited consolidated financial
statements, the Owners do not have any liabilities or obligations of any nature
(whether accrued, absolute, contingent or otherwise).

                                      -21-
<PAGE>

          (h)  Permits, Legal Compliance and Notice of Defects.  No Owner has
               -----------------------------------------------
applied to or entered into any agreement with any governmental official, agency
or body or with any other Person or entity with respect to any modification,
variance or exception regarding zoning, building codes and similar laws and
regulations that materially and adversely affects the value, use or operation of
any of the Properties.  Except as disclosed in due diligence materials delivered
to the Acquirer, the Owners have received no written notice from any
governmental authority that (i) the Owners do not have all licenses, permits and
certificates necessary for the use and operation of the Properties (as presently
used and operated), including, without limitation, all certificates of occupancy
necessary for the occupancy of such Properties, except where the failure to have
such licenses, permits and certificates would not materially and adversely
affect the value, use or operation of the Property affected thereby, (ii) the
Properties or the current use thereof violates any governmental law, rule
regulation or code (exclusive of any Environmental Laws, which are addressed in
Section 4.2(i)) or any covenants or restrictions encumbering such Properties,
except such violations which would not materially and adversely affect the
value, use or operation of the Property affected thereby, or (iii) there is any
pending or contemplated condemnation or other eminent domain proceeding
affecting all or any part of the Properties.  Except as disclosed in due
diligence materials delivered to the Acquirer, the Owners have no knowledge that
any structural, mechanical, electrical, plumbing, roofing or other major system
of any Property are in need of material repair or replacement.  To the Owners'
knowledge, the tenants of the Properties, now have in force insurance policies
relating to such Properties as required by the Leases.  Except as disclosed in
due diligence materials delivered to the Acquirer, no Owner has received any
written notice from any insurance company or underwriter of any defect that
would materially adversely affect the insurability of any of the Properties.
With respect to any Property for which the current owner's title insurance
policy does not contain an ALTA 3.1 zoning endorsement and for which the Sellers
have not provided to the Acquirer a zoning opinion letter, each of such
Properties is currently zoned with a classification that permits the ownership
and operation of an automobile dealership and the development, use and operation
of such Property as currently being used without special exception or permit.
The Owners have not received any written notice from or on behalf of a person or
entity that can assert a claim in connection with a violation of a Permitted
Exception that the Owners have not performed all obligations under and no Owner
is in default in complying with the terms and provisions of any of the
covenants, conditions, restrictions, rights-of-way and easements constituting
one or more of the Permitted Exceptions.

          (i)  Environmental.  The Owners have no knowledge, without independent
               -------------
investigation, of any violation of Environmental Laws related to the Properties
or the presence or release of Hazardous Materials on or from such Properties,
except as reflected in the environmental reports listed or otherwise disclosed
on Schedule 4.2(i).  Schedule 4.2(i) is a list of all written environmental
   ---------------   ---------------
reports and results of environmental inspections and tests in the possession of
the Owners, which list is complete in all material respects.

                                      -22-
<PAGE>

          (j)  No Employees.  The Owners have never maintained any deferred
               ------------
compensation plan, bonus plan, stock option plan, employee stock purchase plan,
incentive compensation plan, agreement, arrangement or commitment.  As of the
Closing Date, the Owners will have no employees.  As of the Closing Date, no
former employee of the Sellers or Owners will have any claims against any Owner
in connection with any employment contract, agreement or employment relationship
between such employee and any Owner.  The Owners have never maintained or had
any obligation to contribute to (i) an "employee pension benefit plan," as
defined in Section 3(2) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), which is not a "multi-employer plan" within the meaning of
Section 3(37) of ERISA, (ii) an "employee welfare benefit plan," as defined in
Section 3(1) of ERISA which is not a "multi-employer plan" within the meaning of
Section 3(37) of ERISA, or (iii) a Pension Benefit Plan or Welfare Benefit Plan
which is a "multi-employer plan" as defined in Section 3(37) of ERISA.

forth in the Recitals, are owned by Smith and MMR Holdings, respectively, free
and clear of all Liens. The Membership Interests are owned by Smith and SFC, as

owner's title insurance policy for each Property. With respect to each Property,
since the effective date of the owner's title insurance policy therefor, the
applicable Owner has not sold, transferred or encumbered any interest in such
Property or suffered any Liens (other than Permitted Exceptions) to be placed
against such Property, and no claim has been made or judgment entered against
the applicable Owner in connection with such Property.

                    (ii)  The Interests were validly issued, fully paid and,
except for any general partnership interest, non-assessable, and constitute all
of the issued and outstanding partnership interests of MMR Viking and membership
interests of MMR Holdings and MMR Tennessee, as the case may be; all such
Interests were not issued in violation of any preemptive rights. The Interests
were issued in compliance with applicable law and the relevant organizational
documents (as then in effect). There are no enforceable rights, subscriptions,
warrants, options, conversion rights, preemptive rights or agreements of any
kind outstanding to purchase or to otherwise acquire any of the interests of MMR
Holdings, MMR Viking or MMR Tennessee or in any securities or obligations of any
kind convertible into any interests in MMR Holdings, MMR Viking or MMR Tennessee
or other equity interests or profit participations of any kind. The Owners are
subject to no liabilities, whether matured or contingent, whether disclosed or
undisclosed, except for (A) such liabilities which have been taken into account
in determining the Adjusted Purchase Price, (B) any Mortgage Debt or other
mortgage debt to be repaid or assumed as of the Closing Date, and (C) any other

responsibility of such Seller or Owner). As of the Closing Date, the Owners will
be subject to no liabilities,

                                      -23-

whether matured or contingent, whether disclosed or undisclosed, except for (A)
such liabilities which have been taken into account in determining the Adjusted
Purchase Price, and (B) any Mortgage Debt or other mortgage debt to be repaid or
assumed as of the Closing Date.

             (l)  No Brokers.  Neither the Owners nor any of their respective
                  ----------
officers, partners, directors, employees or agents has employed or made any
agreement with any broker, finder or similar agent or any Person or firm which
will result in the obligation of the Acquirer or any of its affiliates to pay
any finder's fee, brokerage fees or commissions or similar payment in connection
with the transactions contemplated by this Agreement.

             (m)  Solvency. Each Owner is solvent as of the date hereof and will
                  --------
be solvent immediately following the transaction contemplated by this Agreement.

                          COOPERATION ON TAX MATTERS

     .1 Cooperation on Tax Matters.
        --------------------------

          (a) The Sellers, the Owners and the Acquirer agree to furnish, or
cause to be furnished to the other, upon request, as promptly as practicable,
such information (including access to books and records) and assistance relating
to the Properties as is reasonably necessary for (i) the filing of any Tax
Return, the preparation for any Tax audit, and the prosecution or defense of any
claim, suit and proceeding relating to any proposed Tax adjustment which may
affect the allocation of tax liabilities under this Agreement, and (ii) the
performance by the Sellers, the Owners and the Acquirer of their respective
obligations under this Agreement.  The Sellers, the Owners and the Acquirer
shall keep all such information and documents received by them confidential
unless otherwise required to be disclosed by law or by the order of a court.

          (b) The Sellers, the Owners and the Acquirer agree to give the other
reasonable notice prior to transferring, discarding or destroying any such books
and records relating to Tax matters of the Properties and, if so requested, the
Sellers, the Owners and the Acquirer shall allow the requesting party to take
possession of such books and records.

          (c) The Sellers, the Owners and the Acquirer shall cooperate with
each other in the conduct of any audit or other proceedings with respect to the
Properties for any Tax purposes.

          (d) The parties recognize that the transfer of Interests provided
herein shall result in a termination of the Owners for Federal and state income

of Interests provided herein, the Owners shall be disregarded for Federal and
state income tax purposes.

               (i)  The Sellers shall have the sole responsibility for preparing
the Tax Returns of the Owners for periods prior to and ending on the Closing
Date. The Acquirer shall allow the Sellers reasonable access to the records of
the Owners for the purpose of preparing such Tax Returns.

               (ii) The Sellers shall be liable for, shall have the sole
responsibility for paying and hereby jointly and severally agree to indemnify

<PAGE>

               (i)   Each Owner is either (A) taxed as a partnership or (B)
disregarded for Federal and state income tax purposes. No Owner or any member or
partner of any Owner has made or will make an election under Treasury Regulation
section 301.7701-3(c) that has caused or may cause any Owner to be classified as
an association taxable as a corporation for Federal or state income tax
purposes.

               (ii)  The Owners are currently the beneficiaries of an extension
of time within which to file their 1998 Tax Returns. In accordance with Section
9.1(d)(i), Sellers shall prepare the 1998 and partial year 1999 Tax Returns for
Owners on or before October 15, 1999. The only jurisdictions in which the Owners
are required to file Tax Returns relating to income (other than federal Tax
Returns relating to income) are the jurisdictions in which the Properties are
located, and no claim has ever been made by an authority in a jurisdiction other
than the jurisdictions in which the Properties are located that any Owner may be
subject to taxation.

               (iii) Each Owner has withheld and paid all taxes required to have
been withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, partner, member, or other third party.

          (b) No Federal, state or local taxing authority has asserted any tax
deficiency, lien, interest or penalty against any Owner (or any property owned
by any Owner) which has not been paid.  No Owner has received any written notice
of audit or investigation that is currently pending, and are not currently under
any audit or investigation relating to Taxes that has not been resolved as of
the date hereof.  No event has occurred and no condition or circumstance exists
which presents a material risk that any tax deficiency, lien, interest or
penalty will be imposed on any Owner (or any property owned by any Owner).

                                  ARTICLE 10
            DISPOSITION OF CASH ASSETS AND TERMINATION OF CONTRACTS
                          OF THE OWNERS UPON CLOSING

     .1 Prior to the Closing, the Owners may distribute to the Sellers or
their designees all of the cash assets of the Owner and the personal property of
the Owners that, in the ordinary course of business, is located in the Owners'
principal executive offices (the "Distributed Assets"), except for (a) any
security deposits and any amounts representing prepaid rent or other income
under the Leases applicable to any period of time after the Closing, (b)
insurance proceeds to be given to the Acquirer pursuant to Section 3.9 hereof,
and (c) proceeds from any condemnation awards under Section 3.10 hereof
regarding any Property and received after the Effective Date and before the
Closing Date, which excepted amounts shall be retained by the Owners for the
benefit of the Acquirer.

     .2 Effective as of the first Closing Date, each Owner shall have (a)
terminated all contracts and agreements to which it is a party (other than this
Agreement), and (b) discharged

                                      -33-
<PAGE>

all obligations and liabilities that have accrued as of the Closing Date and
paid all amounts payable (other than any security deposits under the Leases).

                             DEFAULT AND REMEDIES

     .1 Default by the Acquirer.  If this transaction fails to close as a
        -----------------------
result of a material default by the Acquirer with respect to any of the terms of
this Agreement, and such material default continues for a period of ten (10)
days after the Sellers notify the Acquirer in writing of such default, the
Sellers' sole and exclusive remedy for such material default shall be the right
to cancel and terminate this Agreement and receive and retain the Deposit.
Unless the Sellers waive the Acquirer's default in writing within five (5) days
after the expiration of the 10-day period specified in the preceding sentence,
or such default is cured within such 10-day period, this Agreement shall
automatically terminate effective fifteen (15) days after the notice of default
is given without the necessity of further notice being given.  Upon such
termination, each party shall be released from all duties or obligations
contained herein and the Chicago Title Insurance Company shall immediately pay
the Deposit to the Sellers as liquidated damages as the sole and exclusive
remedy of the Sellers, it being understood and agreed that the Sellers are
hereby releasing and/or waiving any right they might have to either specifically
enforce this Agreement or to sue for damages.  The Sellers have agreed to this
liquidated damage provision because of the difficulty of ascertaining the
Sellers' actual damages given the uncertainties of the real estate market,
fluctuating property values and differences of opinion with respect to such
matters.

     .2 Default by Sellers and Owners.  At any time prior to the Closing Date,
        -----------------------------
if there shall have been a material breach of any covenant, representation or
warranty of any Seller or Owner hereunder, or failure of any condition to the
Acquirer's obligation to close which is not or cannot be cured prior to five (5)
Business Days before the Closing Date (except with respect to a default
resulting solely in the exclusion of one or more Properties by Seller pursuant
to clause (z) of Section 2.6 or the exclusion of one or more Properties by the
Acquirer pursuant to Section 2.6, which shall be governed by the terms of
Section 2.6), then the Acquirer may elect, by written notice to the Sellers (a)
to terminate this Agreement, whereupon the Deposit shall be returned to the
Acquirer and the parties shall have no further rights or obligations hereunder
except as otherwise expressly set forth herein, which notice shall be given by
the Acquirer within thirty (30) days after becoming aware of such material
breach, failure or material adverse change or development or such longer period
to which the Sellers may agree; (b) to waive the default or failure to perform
and proceed with the Closing; or (c) to pursue any legal or equitable remedies
to which the Acquirer may be entitled on account of the foregoing, including,
without limitation, specific performance.

against, for and in respect of, any and all damages, losses, obligations,
liabilities, demands, judgments, injuries, penalties, claims, actions or causes
of action, encumbrances, costs and expenses (including, without limitation,
reasonable attorneys' fees and expert witness fees), suffered, sustained,
incurred or required to be paid by any Acquirer indemnitee (collectively,
"Acquirer's Damages") arising out of, based upon, in connection with, or as a
result of:

          (a) the untruth, inaccuracy or breach of any representation and
warranty of the Sellers or Owners (regardless of any knowledge thereof by the
Acquirer at or prior to the Closing) contained in or made pursuant to this
Agreement, including any Schedule or certificate delivered hereunder or in
connection herewith; provided, however, the Sellers shall have no obligation to
pay Acquirer's Damages pursuant to this Section 12.1(a) unless and until (and
only to the extent that) all claims with respect to Acquirer's Damages pursuant
to this Section 12.1(a) exceed a cumulative aggregate of total of Fifty Thousand
Dollars ($50,000.00);

          (b) the breach or non-fulfillment of any covenant or agreement of any
Seller or Owners contained in this Agreement or in any other agreement, document
or instrument delivered hereunder or pursuant hereto; or

          (c) any and all Taxes arising out of or based upon the Distributed
Assets or the distribution thereof as contemplated by Article 10; or

          (d) any liability whether or not asserted or due to the extent
accruing against any Owner or the Properties prior to the Closing except for
breach of representations or warranties addressed in Section 12.1(a).

     .2 Agreement to Indemnify by Acquirer.  Subject to the terms and

conditions of Section 12.5 hereof, the Acquirer hereby agrees to indemnify and
save the Sellers and their successors and assigns (each a "Seller Indemnitee")
harmless from or against, for and in respect of, any and all damages, losses,
obligations, liabilities, demands, judgments, injuries, penalties, claims,
actions or causes of action, encumbrances, costs and expenses (including,

suffered, sustained, incurred or required to be paid by any Seller Indemnitee
arising out of, based upon or in connection with or as a result of:

                                      -35-
<PAGE>

          (a) the untruth, inaccuracy or breach of any representation and
warranty of the Acquirer (regardless of any knowledge thereof by the Sellers at
or prior to the Closing) contained in or made pursuant to this Agreement,
including in any schedule or certificate delivered hereunder or in connection
herewith; or

          (b) the breach or non-fulfillment of any covenant or agreement of the
Acquirer contained in this Agreement or in any other agreement, document or
instrument delivered hereunder or pursuant hereto; or

          (c) any liability to the extent accruing against any Owner or the
Properties after Closing.

     .3 Effectiveness.  The provisions of this Article 12 shall be effective
        -------------
upon consummation of the Closing and, prior to the Closing, shall have no force
and effect.

     .4 Environmental Excluded.  The indemnities set forth in this Article 12
        ----------------------
do not cover indemnification relating to environmental conditions or claims
including, without limitation, asbestosis, with the exception of a breach by the
Sellers or Owners of their representations and warranties in Section 4.2(i).
Each party explicitly reserves all rights with respect to such claims under any
other provision of this Agreement and under applicable law.

     .5 Procedure.  The following provisions govern all actions for indemnity
        ---------
under this Article 12 and any other provision of this Agreement.  Promptly after
receipt by an indemnitee of notice of any claim, such indemnitee shall, if a
claim in respect thereof is to be made against the indemnitor, deliver to the
indemnitor written notice thereof and the indemnitor shall have the right to
participate in and, if the indemnitor agrees in writing that it shall be
responsible for any costs, expenses, judgments, damages and losses incurred by
the indemnitee with respect to such claim, to assume the defense thereof, with
counsel mutually satisfactory to the parties; provided, however, that an
indemnitee shall have the right to retain its own counsel, with the fees and
expenses to be paid by the indemnitor, if the indemnitee reasonably believes
that representation of such indemnitee by the counsel retained by the indemnitor
would be inappropriate due to actual or potential differing interests between
such indemnitee and any other party represented by such counsel in such
proceeding. The failure of an indemnitee to deliver written notice to the
indemnitor within a reasonable time after the indemnitee receives notice of any
such claim shall relieve such indemnitor of any liability to the indemnitee
under this indemnity only if and to the extent that such failure is prejudicial
to the indemnitor's ability to defend such action.  If an indemnitee settles a
claim without the prior written consent of the indemnitor, then the indemnitor
shall be released from liability with respect to such claim unless the
indemnitor has unreasonably withheld such consent.

     .6 Limitation on Liability.  Notwithstanding any other provision in this
        -----------------------
Article 12, the aggregate liability of each Seller, respectively, with respect
to any and all liabilities, claims,

                                      -36-
<PAGE>

demands, losses or damages effected under Section 12.1 shall not exceed the
amount of the Purchase Price allocable to such Seller.

     .7 Exclusivity.  The parties hereto agree that, from and after the
        -----------
Closing Date, with respect to any breach or violation of any representation or
warranty or any covenant, obligation or other term set forth in this Agreement
or the other documents among Sellers and Acquirer delivered in connection
herewith, the only relief and remedy available to a party in respect of such
breach shall be (a) damages, but only to the extent properly claimable hereunder
pursuant to this Article 12 as may be limited pursuant to Section 12.1 or
Section 12.5, (b) specific performance, if a court of competent jurisdiction in
its discretion grants the same, or (c) injunctive or declaratory relief, if a
court of competent jurisdiction in its discretion grants the same.

                                  ARTICLE 13
                                 MISCELLANEOUS

     .1 Survival.  The representations and warranties contained in this
        --------
Agreement and the indemnification obligations and other provisions of this
Agreement that contemplate performance after the Closing shall survive the
Closing for a period of five (5) years from the Closing Date (except that
representations and warranties and related indemnification obligations relating
to any of the Properties shall survive Closing for a period of one (1) year from
the Closing Date) and shall not be deemed to be merged into or waived by the
instruments of the Closing; provided, however, that the representations in
Section 9.2 shall survive the closing until thirty (30) days after the
applicable statute of limitations period has expired.  Notice of a good faith
claim for indemnification under Article 12 must be given in writing by an
indemnitee pursuant to Section 12.5 within five (5) years or one (1) year, as
applicable, after the date of this Agreement if a claim in respect thereof is to
be made against the indemnitor (other than claims arising out of a breach of the
representations and warranties in Section 9.2, for which claims for
indemnification shall be given during the applicable survival period).  The
Acquirer's obligation to pay the Second Purchase Price on the Second Funding
Date, pursuant to Section 2.1 hereof, shall survive the Closing until such
obligation is discharged.

     .2 Expenses.  Except with respect to the Acquisition Expenses as
        --------
otherwise expressly provided herein, each party hereto shall pay its own
expenses incident to this Agreement and the transactions contemplated hereby,
including all costs and expenses incurred by such party in connection with (a)
the performance of any due diligence reviews of the other parties and, as
applicable, the Properties and (b) the acquisition or disposition, as
applicable, of the Interests.

     .3 Additional Actions and Documents.  Each of the parties hereto hereby
        --------------------------------
agrees to use its commercially reasonable efforts to take or cause to be taken
such further actions, to execute, deliver and file or cause to be executed,
delivered and filed such further documents, and to obtain such consents, as may
be necessary or as may be reasonably requested in order to

                                      -37-
<PAGE>

fully effectuate the purposes, terms and conditions of this Agreement. The
obligations of the parties set forth in this Section 13.3 shall survive the
Closing and shall not be deemed to be merged into or waived by any instrument of
conveyance delivered at Closing.

     .4 Remedies Cumulative.  The remedies provided in this Agreement shall be
        -------------------
cumulative and, except as otherwise expressly provided, shall not preclude the
assertion or exercise of any other rights or remedies available by law, in
equity or otherwise.

     .5 Entire Agreement; Amendment.  This Agreement, including the exhibits,
        ---------------------------
schedules and other documents referred to herein or therein or furnished
pursuant hereto or thereto, constitutes the entire agreement among the parties
hereto with respect to the transactions contemplated herein, and supersedes all
prior oral or written agreements, commitments or understandings with respect to
the matters provided for herein.  No amendment, modification or discharge of
this Agreement shall be valid or binding unless set forth in writing and duly
executed and delivered by the party against whom enforcement of the amendment,
modification or discharge is sought.

     .6 Notices.  All notices, demands, requests or other communications which
        -------
may be or are required to be given, served or sent by any party to any other

law or otherwise, without the prior written consent of the other parties hereto;

Agreement to any Affiliate.  Notwithstanding any assignment by the Acquirer of
its rights and obligations under this Agreement, the Acquirer shall remain
liable for its obligations under this Agreement, jointly and severally, with any
assignee.

     .11 No Third Party Beneficiaries.  This Agreement is solely for the
         ----------------------------
benefit of the parties hereto, and no provision of this Agreement shall be
deemed to confer any benefit on any third party.

     .12 Confidentiality.
         ---------------

          (a) Before the Closing Date, no Seller, directly or indirectly, shall
make any public announcement or disclosure of this Agreement or any information
related to this Agreement to third parties, other than their respective auditors
and accountants, legal counsel, tenants and lenders without the prior written
consent of the Acquirer.

          (b) As used herein, "Confidential Material" means, with respect to
each party hereto (the "Providing Party"), all information, whether oral,
written or otherwise, furnished to any other party hereto (the "Receiving
Party") or such Receiving Party's directors, officers, partners, affiliates,
employees, agents or representatives (collectively, "Representatives"), by the
Providing Party and all reports, analyses, compilations, studies and other
material prepared by the Receiving Party or its Representatives (in whatever
form maintained, whether documentary, computer storage or otherwise) containing,
reflecting or based upon, in whole or in part, any such information. The term
"Confidential Material" does not include information which (i) is or becomes
generally available to the public other than as a result of a disclosure by the
Receiving Party, its Representatives or anyone to whom the Receiving Party or
any of its Representatives transmit any Confidential Material in violation of
this Agreement, (ii) is or becomes known or available to the Receiving Party on
a non-confidential basis from a source (other than the Providing Party or
another Receiving Party or one of their Representatives) who is not, to the
knowledge of the Receiving Party after reasonable inquiry, prohibited from
transmitting the information to the Receiving Party or its Representatives by a
contractual, legal, fiduciary or other obligation or (iii) is subsequently
disclosed in any other public disclosure permitted under this Section 13.12.

          (c) Subject to paragraph (d) below or except as required by law or as
ordered by a court of competent jurisdiction, the Confidential Material will be
kept confidential and will not, without the prior written consent of the
Providing Party, be disclosed by the Receiving Party or its Representatives, in
whole or in part, and will not be used by the Receiving Party or its
Representatives, directly or indirectly, for any purpose other than in
connection with this Agreement, the Consolidation or the conducting, negotiating
or advising with respect to a transaction contemplated herein. Moreover, each
Receiving Party agrees to

                                      -40-
<PAGE>

transmit Confidential Material to its Representatives only if and to the extent
that such Representatives need to know the Confidential Material for purposes of
such transaction and are informed by such Receiving Party of the confidential
nature of the Confidential Material and of the terms of this Section 13.12. In
any event, each Receiving Party will be responsible for any actions by its
Representatives which are not in accordance with the provisions hereof.

          (d) In the event that any Receiving Party, its Representatives or
anyone to whom such Receiving Party or its Representatives supply the
Confidential Material, are requested (by oral questions, interrogatories,
requests for information or documents, subpoena, civil investigative demand, any
informal or formal investigation by any government or governmental agency or
authority or otherwise in connection with legal process) to disclose any
Confidential Material, such Receiving Party agrees (i) to immediately notify the
Providing Party of the existence, terms and circumstances surrounding such a
request, (ii) to consult with the Providing Party on the advisability of taking
available legal steps to resist or narrow such request and (iii) if disclosure
of such information is required, to furnish only that portion of the
Confidential Material which, in the opinion of such Receiving Party's counsel,
such Receiving Party is legally compelled to disclose and to cooperate with any
action by the Providing Party to obtain an appropriate protective order or other
reliable assurance that confidential treatment will be accorded the Confidential
Material (it being agreed that the Providing Party shall reimburse the Receiving
Party for all reasonable out-of-pocket expenses incurred by the Receiving Party
in connection with such cooperation).

          (e) The provisions of this Section 13.12 shall terminate upon the
Closing.  In the event of the termination of this Agreement in accordance with
its terms, promptly upon request from a Providing Party, each Receiving Party
shall, except to the extent prevented by law, redeliver to such Providing Party
or destroy all tangible Confidential Material and will not retain any copies,
extracts or other reproductions thereof in whole or in part.  Any such
destruction shall be certified in writing to such Providing Party by an
authorized officer of the Receiving Party supervising the same.  Notwithstanding
the foregoing, each Receiving Party and one Representative designated by each
Receiving Party shall be permitted to retain one permanent file copy of each
document constituting Confidential Material.

     .13 Severability.  If any provision of this Agreement shall be held
         ------------
invalid, illegal or unenforceable, the validity, legality or enforceability of
the other provisions hereof shall not be affected thereby, and there shall be
deemed substituted for the provision at issue a valid, legal and enforceable
provision as similar as possible to the provision at issue.

     .14 Acquirer Access to Information.  Upon the Acquirer's reasonable
         ------------------------------
request, at any time before or after the Closing Date, each Seller and Owner
shall provide the Acquirer reasonable access to the books and records of the
Properties and all related information in order for the Acquirer to verify any
payments or receipts from tenants, suppliers, service providers and any other
party.

                                      -41-
<PAGE>

     .15 Information and Audit Cooperation.  At the Acquirer's request, at any
         ---------------------------------
time before or after the Closing Date, the Sellers and the Owners shall provide
to the Acquirer's designated independent auditor access to the books and records
of the Properties and all related information regarding the period for which the
Acquirer or any of its Affiliates are required to have the Properties audited
under the regulations of the Securities and Exchange Commission, and a
representation letter regarding the books and records of the Properties
substantially in the form of Exhibit 13.15 in connection with the normal course
                             -------------
of auditing the Properties in accordance with generally accepted auditing
standards.

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

     .17 Headings.  The headings contained in this Agreement are for reference
         --------
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

     .18 Limitation of Liability.  Any obligation or liability whatsoever of
         -----------------------
the Acquirer which may arise at any time under this Agreement or any obligation
or liability which may be incurred by it pursuant to any other instrument,
transaction or undertaking contemplated hereby shall be satisfied, if at all,
out of the Acquirer's assets only.  No such obligation or liability shall be
personally binding upon, nor shall resort for the enforcement thereof be had to,
the property of any of its shareholders, trustees, officers, employees or
agents, regardless of whether such obligation or liability is in the nature of
contract, tort or otherwise.

     .19 Waiver of Jury Trial.  TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE
         --------------------
PARTIES HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY.  THE PROVISIONS OF THIS SECTION 13.19 SHALL
SURVIVE ANY TERMINATION OF THIS AGREEMENT.

     .20 No Board Seat.  The Sellers acknowledge and agree that nothing
         -------------
contained in this Agreement shall be construed or deemed to grant any Seller the
power or right to designate or appoint a member of the Board of Trustees of
Capital Automotive REIT, a Maryland real estate investment trust.
