cause the removal of any disapproved exceptions or objections, in which case
Seller shall (at its sole cost) remove the exceptions or objections (or, if

objections) before COE. Seller shall notify Buyer in writing within five (5)
days after receiving Buyer's written notice of disapproval of any exception, if
Seller does not intend to remove (or endorse over) any such exception and/or
objection. Seller's lack of response shall be deemed as Seller's refusal to
remove the objectionable exceptions (or obtain title insurance endorsements over
said exceptions and objections, if acceptable to Buyer) prior to COE. In the

a prior Report, Buyer shall have until the later of (i) the expiration of the

or objections. If Seller serves notice to Buyer that Seller does not intend to
remove such exceptions and objections before COE, Buyer shall, within ten (10)
days thereafter, notify Seller and Escrow Agent in writing of Buyer's election
to either (i) terminate this Agreement, whereupon the Earnest Money Deposit plus
interest shall be returned to Buyer and all obligations shall terminate, or (ii)
Buyer may waive such objections and the transaction shall close as scheduled. If
written notice of dissatisfaction is not timely given by Buyer to Seller
pursuant to this Section 6, then Buyer shall be deemed to have disapproved of
the condition of the title of the Property as shown by the Report, and shall
have elected to terminate this Agreement.

            (a) The Study Period. Buyer shall have until the later of 5:00 p.m.

            (g) Seller has not and will not, without the prior written consent

comparable insurance coverage, if any, for the Improvements which Seller is

Materials" shall mean any flammables, explosives, radioactive materials,
hazardous wastes, hazardous and toxic substances or related materials, asbestos
or any material containing asbestos (including, without limitation, vinyl
asbestos tile), or any other substance or material, defined as a "hazardous
substance" by any federal, state, or local environmental law, ordinance, rule or

"Seller's Knowledge" means matters of which A. Russell Poteat is presently
aware, without undertaking any investigation or inquiry whatsoever. If Seller is
unable to renew a warranty as of COE due to changed circumstance outside the

breach or default hereunder; provided, however, in the event a warranty is
materially affected by such a changed circumstance or new knowledge, Tenant
shall

CVS

be entitled to terminate this Agreement upon written notice of such material
change or new knowledge, whereupon the Earnest Money Deposit plus interest shall
be paid immediately by Escrow Agent to Buyer and, except as otherwise provided
in this Agreement, neither of the Parties shall have any further liability or
obligation under this Agreement.

      14. BUYER'S WARRANTIES. Buyer hereby represents to Seller as of the
Effective Date and again as of COE that:

            (a) Buyer has full power and authority to execute, deliver and
perform under this Agreement as well as under the Transfer Documents, specimens
of which are attached hereto as Exhibits;

            (b) there are no actions or proceedings pending or to Buyer's
knowledge, threatened against Buyer which may in any manner whatsoever affect
the validity or enforceability of this Agreement or any of the documents,
specimens of which are attached hereto as Exhibits;

            (c) the execution, delivery and performance of this Agreement and
the Transfer Documents, specimens of which are attached hereto as Exhibits, have
not and will not constitute a breach or default under any other agreement, law
or court order under which Buyer is a party or may be bound;

            (d) should Buyer receive notice or knowledge of any information
regarding any of the matters set forth in this Section 14 after the Effective
Date and prior to COE, Buyer will promptly notify Seller of the same in writing;
and

            (e) all representations made in this Agreement by Buyer shall
survive the execution and delivery of this Agreement and COE for a period of two
hundred seventy (270) days. Buyer shall and does hereby indemnify against and
hold Seller harmless from any loss, damage, liability and expense, together with
all court costs and attorneys' fees, if awarded by a court of law, which Seller
may incur, by reason of any material misrepresentation by Buyer or any material
breach of any of Buyer's warranties. Buyer's indemnity and hold harmless
obligations shall survive COE.

      15. RENTS AND DEPOSITS. Seller and Buyer agree that, in addition to all
other conditions and covenants contained herein, Seller shall deliver to Buyer
and Escrow Agent not later than the day immediately prior to COE information,
certified by Seller to be true and accurate as of the date thereof and as of the
date of COE, with respect to (i) the amount of Tenant's security deposit under
the Lease, if any, and (ii) prepaid and/or abated rents, including, without
limitation, the amount thereof and the date to which such rents have been paid.

      16. BROKER'S COMMISSION. Concerning any brokerage commission, the Parties
agree as follows:

CVS
Alpharetta, GA

                                       11

<PAGE>

            (a) the Parties warrant to one another that they have not dealt with
any finder, broker or realtor in connection with this Agreement except Franklin
Real Estate Group, Inc., M III Companies, and Roger Massell, The Lennox/Massell
Companies (collectively, "Brokers");

            (b) if any person shall assert a claim to a finder's fee or
brokerage commission on account of alleged employment as a finder or broker in
connection with this Agreement (including Brokers), the Party under whom the
finder or broker is claiming shall indemnify and hold the other Party harmless
from and against any such claim and all costs, expenses and liabilities incurred
in connection with such claim or any action or proceeding brought on such claim,
including, but not limited to, counsel and witness fees and court costs in
defending against such claim. The provisions of this subsection shall survive
cancellation of this Agreement or COE; and

            (c) Seller shall be responsible for payment of a commission to
Brokers in an aggregate amount equal to Two Percent (2%) of the Purchase Price,
which commission shall be divided equally among the Brokers and shall be paid at
COE.

      17. CLOSE OF ESCROW. COE shall be on or before 5:00 p.m. MST on the
thirtieth (30th) day after the expiration of the Study Period or such earlier
date as Buyer may choose by giving not less than five (5) days prior written
notice to Seller and Escrow Agent. Buyer may extend the COE date for up to an
additional thirty (30) days upon delivery of written notice to extend the COE
date to Escrow Agent prior to the original COE date and by depositing an
additional Fifty Thousand and no/100 Dollars ($50,000.00) of earnest money with
Escrow Agent. For purposes of this Agreement, any additional earnest money
deposited with Escrow Agent pursuant to this Section 17 shall be added to and
become a part of the Earnest Money Deposit.

      18. ASSIGNMENT. This Agreement may not be assigned by Seller without the
prior written consent of Buyer which consent shall not be unreasonably withheld.
Buyer may assign its rights under this Agreement to an affiliate of Buyer
without seeking or obtaining Seller's consent. Such assignment shall not become
effective until the assignee executes an instrument whereby such assignee
expressly assumes each of the obligations of Buyer under this Agreement,
including specifically, without limitation, all obligations concerning the
Earnest Money Deposit. Buyer may also designate someone other than Buyer, as
grantee and/or assignee, under the Transfer Documents by providing written
notice of such designation at least five (5) days prior to COE. No assignment
shall release or otherwise relieve Buyer from any obligations hereunder.

      19. RISK OF LOSS. Seller shall bear all risk of loss, damage or taking of
the Property which may occur prior to COE. In the event of any loss, damage or
taking prior to COE, Buyer may, at Buyer's sole option, by written notice to
Seller and Escrow Agent, cancel this Agreement whereupon the Earnest Money
Deposit plus interest shall be paid immediately by Escrow Agent to Buyer and,
except as otherwise provided in this Agreement, neither of the Parties shall
have any further liability or obligation hereunder. In the alternative, Buyer
may attempt to negotiate an appropriate downward adjustment of the Price. If
Seller and Buyer cannot agree upon such a downward adjustment within a
reasonable period (not to exceed ten

CVS
Alpharetta, GA

                                       12

<PAGE>

(10) days from the date Buyer receives notice of the loss) Buyer may cancel this
Agreement as provided above. If Buyer waives any such loss or damage to the
Property and closes escrow, Seller shall at COE and as a condition precedent
thereto, pay Buyer or credit Buyer against the Additional Funds the amount of
any insurance or condemnation proceeds, or assign to Buyer, as of COE and in a
form acceptable to Buyer, all rights or claims for relief to the same.

      20. REMEDIES.

            (a) Seller's Breach. If Seller breaches this Agreement, Buyer may,
at Buyer's sole option, either: (i) by written notice to Seller and Escrow
Agent, cancel this Agreement whereupon the Earnest Money Deposit plus interest
shall be paid immediately by Escrow Agent to Buyer and, except as otherwise
provided in this Agreement, neither of the Parties shall have any further
liability or obligation hereunder; or, (ii) seek specific performance against
Seller in which event COE shall be automatically extended as necessary.
Notwithstanding the foregoing, if specific performance is unavailable as a
remedy to Buyer because of Seller's affirmative acts, Buyer shall be entitled to
pursue an action at law or in equity, provided that any monetary judgment
against Seller shall be limited to Two Hundred Thousand Dollars ($200,000.00).

            (b) Buyer's Breach. If Buyer breaches this Agreement, as its sole
remedy Seller shall be entitled to retain the Earnest Money Deposit in
accordance with subsection 5(b) as Seller's agreed and total liquidated damages.
Seller hereby waives any right to seek any equitable or legal remedies against
Buyer.

      21. ATTORNEYS' FEES. If there is any litigation to enforce any provisions
or rights arising herein, the unsuccessful party in such litigation, as
determined by the court, agrees to pay the successful party, as determined by
the court, all costs and expenses, including, but not limited to, reasonable
attorneys' fees incurred by the successful party, such fees to be determined by
the court.

      22. NOTICES.

            (a) Addresses. Except as otherwise required by law, any notice
required or permitted hereunder shall be in writing and shall be given by
personal delivery, or tested telex, or telegram, or telecopies (fax), or any
express or overnight delivery service (e.g., Federal Express), delivery charges

      23. CLOSING COSTS.

            (a) Closing Costs. Seller and Buyer agree to pay closing costs as
indicated in this Agreement and in the escrow instructions attached hereto as
Exhibit F, and by this reference incorporated herein (the "Escrow
Instructions"). At COE, Seller shall pay (i) the costs of releasing all liens,
judgments, and other encumbrances that are to be released and of recording such
releases, (ii) one half the fees and costs due Escrow Agent for its services,
(iii) the transfer tax associated with the sale of the Property, if any, and
(iv) all other costs to be paid by Seller under this Agreement. Buyer shall pay
one half the fees and costs due Escrow Agent for its services. Except as
otherwise provided for in this Agreement, Seller and Buyer will each be

CVS
Alpharetta, GA

                                       14

<PAGE>

solely responsible for and bear all of their own respective expenses, including,
without limitation, expenses of legal counsel, accountants, and other advisors
incurred at any time in connection with pursuing or consummating the transaction
contemplated herein. Real estate taxes shall be prorated based upon the current
valuation and latest available tax rates. All prorations shall be calculated
through escrow as of COE based upon the latest available information, including,
without limitation, a credit to Buyer for any rent prepaid by Tenant for the
period beginning with and including the date on which the closing occurs through
and including the last day of the month in which the closing occurs. All other
credits to Buyer shall be similarly prorated. Any other closing costs not
specifically designated as the responsibility of either Party in the Escrow
Instructions or in this Agreement shall be paid by Seller and Buyer according to
the usual and customary allocation of the same by Escrow Agent. Seller agrees
that all closing costs payable by Seller shall be deducted from Seller's
proceeds otherwise payable to Seller at COE. Buyer shall deposit with Escrow
Agent sufficient cash to pay all of Buyer's closing costs. Except as provided in
this Section 23(a), Seller and Buyer shall each bear their own costs in regard
to this Agreement.

            (b) Post-Closing Adjustment. If after COE, the parties discover any
errors in adjustments and apportionments or additional information becomes
available which would render the closing prorations materially inaccurate, the
same shall be corrected as soon after their discovery as possible. The provision
of this Section 23(b) shall survive COE except that no adjustment shall be made
later than two (2) months after COE unless prior to such date the Party seeking
the adjustment shall have delivered a written notice to the other Party
specifying the nature and basis for such claim. In the event that such claim is
valid, the Party against whom the claim is sought shall have ten (10) days in
which to remit any adjustment due.

            (c) Instructions. This Agreement, together with the Escrow
Instructions, shall constitute escrow instructions for the transaction
contemplated herein. Such escrow instructions shall be construed as applying
principally to Escrow Agent's employment.

      24. ESCROW CANCELLATION CHARGES. If escrow fails to close because of
Seller's default, Seller shall be liable for any cancellation charges of Escrow
Agent. If escrow fails to close because of Buyer's default, Buyer shall be
liable for any cancellation charges of Escrow Agent. If escrow fails to close
for any other reason, Seller and Buyer shall each be liable for one half of any
cancellation charges of Escrow Agent. The provisions of this Section 24 shall
survive cancellation of this Agreement.

      25. APPROVALS. Concerning all matters in this Agreement requiring the
consent or approval of any Party, the Parties agree that any such consent or
approval shall not be unreasonably withheld unless otherwise provided in this
Agreement.

      26. RELEASES. Except as expressly provided in this Agreement, Seller and
anyone claiming through Seller hereby releases Tenant from any and all claims of
whatever kind or nature, in law or equity, whether now known or unknown to
Seller, whether contingent or matured, that Seller may now have or hereafter
acquire against Tenant for any costs, loss, liability, damage, expenses, demand,
action or cause of action arising from or related to the Lease arising from
events occurring prior to COE.

      27. ADDITIONAL ACTS. The Parties agree to execute promptly such other
documents and to perform such other acts as may be reasonably necessary to carry
out the purpose and intent of this Agreement.

      28. GOVERNING LAW/JURISDICTION/VENUE. This Agreement shall be governed by
and construed or enforced in accordance with the laws of the State of Georgia.

      29. CONSTRUCTION. The terms and provisions of this Agreement represent the
results of negotiations among the Parties, each of which has been represented by
counsel of its own choosing, and neither of which has acted under any duress or
compulsion, whether legal, economic or otherwise. Consequently, the terms and
provisions of this Agreement shall be interpreted and construed in accordance
with their usual and customary meanings, and the Parties each hereby waive the
application of any rule of law which would otherwise be applicable in connection
with the interpretation and construction of this Agreement that ambiguous or
conflicting terms or provisions contained in this Agreement shall be interpreted
or construed against the Party whose attorney prepared the executed Agreement or
any earlier draft of the same.

      30. TIME OF ESSENCE. Time is of the essence of this Agreement. However, if
this Agreement requires any act to be done or action to be taken on a date which
is a Saturday, Sunday or legal holiday, such act or action shall be deemed to
have been validly done or taken if done or taken on the next succeeding day
which is not a Saturday, Sunday or legal holiday, and the successive periods
shall be deemed extended accordingly.

      31. INTERPRETATION. If there is any specific and direct conflict between,
or any ambiguity resulting from, the terms and provisions of this Agreement and
the terms and provisions of any document, instrument or other agreement executed
in connection herewith or in furtherance hereof, including any Exhibits hereto,
the same shall be consistently interpreted in such manner as to give effect to
the general purposes and intention as expressed in this Agreement which shall be
deemed to prevail and control.

      32. HEADINGS. The headings of this Agreement are for reference only and
shall not limit or define the meaning of any provision of this Agreement.

      33. FAX AND COUNTERPARTS. This Agreement may be executed by facsimile
and/or in any number of counterparts. Each party may rely upon any facsimile or
counterpart copy as if it were one original document.

      34. INCORPORATION OF EXHIBITS BY REFERENCE. All Exhibits to this Agreement
are fully incorporated herein as though set forth at length herein.

      35. SEVERABILITY. If any provision of this Agreement is unenforceable, the
remaining provisions shall nevertheless be kept in effect.

      36. ENTIRE AGREEMENT. This Agreement contains the entire agreement between
the Parties and supersedes all prior agreements, oral or written, with respect
to the subject matter hereof. The provisions of this Agreement shall be
construed as a whole and not strictly for or against any Party.

      37. SEC S-X 3-14 Audit. Seller acknowledges that Buyer may elect to assign
all of its right, title and interest in and to this Agreement to a publicly
registered company ("Registered Company") promoted by the Buyer. In the event
Buyer's assignee under this Agreement is a Registered Company, such Registered
Company will be required to make certain filings with the U.S. Securities and
Exchange Commission required under SEC Rule S-X 3-14 (the "SEC Filings") that
relate to the most recent pre-acquisition fiscal year (the "Audited Year") for
the Property. To assist the Registered Company with the preparation of the SEC
Filings, Seller agrees to provide Buyer with financial information regarding the
Property for the Audited Year requested by Buyer and/or Buyer's auditors. Such
information may include, but is not limited to, bank statements, operating
statements, general ledgers, cash receipts schedules, invoices for expenses and
capital improvements, insurance documentation, and accounts receivable aging
related to the Property ("SEC Filing Information"). Seller shall deliver the SEC
Filing Information requested by Buyer prior to the expiration of the Study
Period, and Seller agrees to cooperate with Buyer and Buyer's auditors regarding
any inquiries by Buyer or Buyer's auditors following receipt of such
information, including delivery by Seller of an executed representation letter
prior to COE in form and substance requested by Buyer's auditors ("SEC Filings
Letter"). A sample SEC Filings Letter is attached to the Purchase Agreement as
Exhibit G; however, Buyer's auditors may require additions and/or revisions to
such letter following review of the SEC Filing Information provided by Seller.
Seller consents to the disclosure of the SEC Filing Information in any SEC
Filings by the Registered Company. Buyer shall reimburse Seller for Seller's
reasonable costs associated with providing the SEC Filing Information. The
provisions of this Section 37 shall survive the COE for a period of one (1)
year.
