Company and may collect and deposit into any such account or accounts, and
disburse from any such account or accounts, any money on behalf of the Company,
under such terms and conditions as the Board may approve, provided that no funds
shall be commingled with the funds of the Advisor; and the Advisor shall from
time to time render appropriate accountings of such collections and payments to
the Board and to the auditors of the Company.

     6.   Records; Access. The Advisor shall maintain appropriate records of all
          ---------------
its activities hereunder and make such records available for inspection by the
Board and by counsel, auditors and authorized agents of the Company, at any time
or from time to time during normal business hours. The Advisor shall at all
reasonable times have access to the books and records of the Company.

     7.   Limitations on Activities.  Anything else in this Agreement to the
          -------------------------
contrary notwithstanding, the Advisor shall refrain from taking any action
which, in its sole judgment made in good faith, would (a) adversely affect the
status of the Company as a REIT, (b) subject the Company to regulation under the
Investment Company Act of 1940, as amended, or (c) violate any law, rule,
regulation or statement of policy of any governmental body or agency having
jurisdiction over the Company, its Shares or its Securities, or otherwise not be
permitted by the Articles of Incorporation or Bylaws of the Company, except if
such action shall be ordered by the Board, in which case the Advisor shall
notify promptly the Board of the Advisor's judgment of the potential impact of
such action and shall refrain from taking such action until it receives further
clarification or instructions from the Board.  In such event the Advisor shall
have no liability for acting in accordance with the specific instructions of the
Board so given. Notwithstanding the foregoing, the Advisor, its directors,
officers, employees and stockholders, and stockholders, directors and officers
of the Advisor's Affiliates shall not be liable to the Company or to the Board
or stockholders for any act or omission by the

                                       11
<PAGE>

Advisor, its directors, officers or employees, or stockholders, directors or
officers of the Advisor's Affiliates except as provided in Paragraphs 20 and 21
of this Agreement.

     8.   Relationship with Directors.  Directors, officers and employees of the
          ---------------------------
Advisor or an Affiliate of the Advisor or any corporate parents of an Affiliate,
or directors, officers or stockholders of any director, officer or corporate
parent of an Affiliate may serve as a Director and as officers of the Company,
except that no director, officer or employee of the Advisor or its Affiliates
who also is a Director or officer of the Company shall receive any compensation
from the Company for serving as a Director or officer other than reasonable
reimbursement for travel and related expenses incurred in attending meetings of
the Board.

     9.   Fees.
          ----
     (a)  Acquisition Fees and Expenses. The Advisor may receive as compensation
payable by the Company for services rendered in connection with the
investigation, selection and acquisition (by purchase, investment or exchange)
of Property Acquisition Fees in an amount equal to up to 3% of Gross Proceeds
and Acquisition Expenses in an amount equal to up to .5% of Gross Proceeds. The
Acquisition Fees shall be reduced to the extent that, and, if necessary to
limit, the total compensation paid to all persons involved in the acquisition of
any Property to the amount customarily charged in arm's-length transactions by
other persons or entities rendering similar services as an ongoing public
activity in the same geographical location and for comparable types of
Properties and to the extent that other acquisition fees, finder's fees, real
estate commissions, or other similar fees or commissions are paid by any person
in connection with the transaction.

     (b)  Subordinated Disposition Fee.  If the Advisor or an Affiliate provides
a substantial amount of the services (as determined by a majority of the
Independent Directors) in connection with the Sale of one or more Properties,
the Advisor or an Affiliate shall receive a Subordinated Disposition Fee equal
to the lesser of (i) one-half of a Competitive Real Estate Commission or (ii) 3%
of the sales price of such Property or Properties. The Subordinated Disposition
Fee will be paid only if Stockholders have received total Dividends in an amount
equal to the sum of their aggregate Invested Capital and their aggregate
Stockholders' 8% Return.  To the extent that Subordinated Disposition Fees are
not paid by the Company on a current basis due to the foregoing limitation, the
unpaid fees will be accrued and paid at such time as the subordination
conditions have been satisfied. The Subordinated Disposition Fee may be paid in
addition to real estate commissions paid to non-Affiliates, provided that the
total real estate commissions paid to all Persons by the Company shall not
exceed an amount equal to the lesser of (i) 6% of the Contract Sales Price of a
Property or (ii) the Competitive Real Estate Commission. In the event this
Agreement is terminated prior to such time as the Stockholders have received
total Dividends in an amount equal to 100% of Invested Capital plus an amount
sufficient to pay the Stockholders' 8% Return through the Termination Date, an
appraisal of the Properties then owned by the Company shall be made and the
Subordinated Disposition Fee on Properties previously sold will be deemed earned
if the Appraised Value of the Properties then owned by the Company plus total
Dividends received prior to the Termination Date equals 100% of Invested Capital
plus an amount sufficient to pay the Stockholders' 8% Return through the
Termination Date. Upon Listing, if the Advisor has

                                       12
<PAGE>

accrued but not been paid such Subordinated Disposition Fee, then for purposes
of determining whether the subordination conditions have been satisfied,
Stockholders will be deemed to have received a Dividends in the amount equal to
the product of the total number of Shares outstanding and the average closing
price of the Shares over a period, beginning 180 days after Listing, of 30 days
during which the Shares are traded.

     (c)  Subordinated Share of Net Sales Proceeds.  The Subordinated Share of
Net Sales Proceeds shall be payable to the Advisor in an amount equal to 10% of
Net Sales Proceeds remaining after the Stockholders have received Dividends
equal to the sum of the Stockholders' 8% Return and 100% of Invested Capital.
Following Listing, no Subordinated Share of Net Sales Proceeds will be paid to
the Advisor.

     (d)  Subordinated Incentive Fee.  Upon Listing, the Advisor shall be
entitled to the Subordinated Incentive Fee in an amount equal to 10% of the
amount by which (i) the market value of the outstanding stock of the Company,
measured by taking the average closing price or average of bid and asked price,
as the case may be, over a period of 30 days during which the stock is traded,
with such period beginning 180 days after Listing (the "Market Value"), plus the
total of all Dividends paid to Stockholders from the Company's inception until
the date of Listing, exceeds (ii) the sum of (A) 100% of Invested Capital and
(B) the total Dividends required to be paid to the Stockholders in order to pay
the Stockholders' 8% Return from inception through the date of Listing. The
Company shall have the option to pay such fee in the form of cash, Shares, a
promissory note or any combination of the foregoing.  The Subordinated Incentive
Fee will be reduced by the amount of any prior payment to the Advisor of a
deferred, Subordinated Share of Net Sales Proceeds from a Sale or Sales of a
Property.  In the event the Subordinated Incentive Fee is paid to the Advisor
following Listing, no other performance fee will be paid to the Advisor.

     (e)  Loans from Affiliates.  If any loans are made to the Company by an
Affiliate of the Advisor, the maximum amount of interest that may be charged by
such Affiliate shall be the lesser of (i) 1% above the prime rate of interest
charged from time to time by The Bank of New York and (ii) the rate that would
be charged to the Company by unrelated lending institutions on comparable loans
for the same purpose. The terms of any such loans shall be no less favorable
than the terms available between non-Affiliated Persons for similar commercial
loans.

     (f)  Changes to Fee Structure. In the event of Listing, the Company and the
Advisor shall negotiate in good faith to establish a fee structure appropriate
for a perpetual-life entity. A majority of the Independent Directors must
approve the new fee structure negotiated with the Advisor. In negotiating a new
fee structure, the Independent Directors shall consider all of the factors they
deem relevant, including, but not limited to: (i) the amount of the advisory fee
in relation to the asset value, composition and profitability of the Company's
portfolio; (ii) the success of the Advisor in generating opportunities that meet
the investment objectives of the Company; (iii) the rates charged to other REITs
and to investors other than REITs by Advisors performing the same or similar
services; (iv) additional revenues realized by the Advisor and its Affiliates
through their relationship with the Company, including loan

                                       13
<PAGE>

administration, underwriting or broker commissions, servicing, engineering,
inspection and other fees, whether paid by the Company or by others with whom
the Company does business; (v) the quality and extent of service and advice
furnished by the Advisor; (vi) the performance of the investment portfolio of
the Company, including income, conversion or appreciation of capital, and number
and frequency of problem investments; and (vii) the quality of the Property
portfolio of the Company in relationship to the investments generated by the
Advisor for its own account. The new fee structure can be no more favorable to
the Advisor than the current fee structure.

     10.    Expenses.
            --------
     (a)    In addition to the compensation paid to the Advisor pursuant to
Paragraph 9 hereof, the Company shall pay directly or reimburse the Advisor for
all of the expenses paid or incurred by the Advisor in connection with the
services it provides to the Company pursuant to this Agreement, including, but
not limited to:

     (i)    the Company's Organizational and Offering Expenses; provided,
however, that within 60 days after the end of the month in which an Offering
terminates, the Advisor shall reimburse the Company for any Organizational and
Offering Expenses reimbursement received by the Advisor pursuant to this
Paragraph 10, to the extent that such reimbursement exceeds 3% of the Gross
Proceeds. The Advisor shall be responsible for the payment of all the Company's
Organizational and Offering Expenses in excess of 3% of the Gross Proceeds;

     (ii)   Acquisition Expenses incurred in connection with the selection and
acquisition of Properties at the lesser of the actual cost or 90% of the
competitive rate charged by unaffiliated persons providing similar goods and
services in the same geographic location;

     (iii)  the actual cost of goods and services used by the Company and
obtained from entities not affiliated with the Advisor, other than Acquisition
Expenses, including brokerage fees paid in connection with the purchase and sale
of securities;

     (iv)   interest and other costs for borrowed money, including discounts,
points and other similar fees;

     (v)    taxes and assessments on income or Property and taxes as an expense
of doing business;

     (vi)   costs associated with insurance required in connection with the
business of the Company or by the Board;

     (vii)  expenses of managing and operating Properties owned by the Company,
whether payable to an Affiliate of the Company or a non-affiliated Person.

     (viii) all expenses in connection with payments to the Board and meetings
of the Board and Stockholders;

                                       14
<PAGE>

     (ix)    expenses associated with Listing or with the issuance and
distribution of Shares and Securities, such as selling commissions and fees,
advertising expenses, taxes, legal and accounting fees, Listing and registration
fees, and other Organization and Offering Expenses;

     (x)     expenses connected with payments of Dividends in cash or otherwise
made or caused to be made by the Company to the Stockholders;

     (xi)    expenses of organizing, revising, amending, converting, modifying,
or terminating the Company or the Articles of Incorporation;

     (xii)   expenses of maintaining communications with Stockholders, including
the cost of preparation, printing, and mailing annual reports and other
Stockholder reports, proxy statements and other reports required by governmental
entities;

     (xiii)  administrative service expenses (including personnel costs;
provided, however, that no reimbursement shall be made for costs of personnel to
the extent that such personnel perform services in transactions for which the
Advisor receives a separate fee); and

     (xiv)   audit, accounting and legal fees.

     (b)     Expenses incurred by the Advisor on behalf of the Company and
payable pursuant to this Paragraph 10 shall be reimbursed no less than monthly
to the Advisor. The Advisor shall prepare a statement documenting the expenses
of the Company during each quarter, and shall deliver such statement to the
Company within 45 days after the end of each quarter.

     11.     Other Services.  Should the Board request that the Advisor or any
             --------------
director, officer or employee thereof render services for the Company other than
set forth in Paragraph 3, such services shall be separately compensated at such
rates and in such amounts as are agreed by the Advisor and the Independent
Directors of the Company, subject to the limitations contained in the Articles
of Incorporation, and shall not be deemed to be services pursuant to the terms
of this Agreement.

     12.     Fidelity Bond.  The Advisor shall maintain a fidelity bond for the
             -------------
benefit of the Company which bond shall insure the Company from losses of up to
$200,000 per occurrence and shall be of the type customarily purchased by
entities performing services similar to those provided to the Company by the
Advisor.

     13      Reimbursement to the Advisor.  The Company shall not reimburse the
             ----------------------------
Advisor at the end of any fiscal quarter Operating Expenses that, in the four
consecutive fiscal quarters then ended (the "Expense Year") exceed (the "Excess
Amount") the greater of 2% of Average Invested Assets or 25% of Net Income (the
"2%/25% Guidelines") for such year. Any Excess Amount paid to the Advisor during
a fiscal quarter shall be repaid to the Company. If there is an Excess Amount in
any Expense Year and the Independent Directors determine that such excess was
justified, based on unusual and nonrecurring factors which they deem sufficient,
the Excess Amount may be carried over and included in Operating Expenses

                                       15

<PAGE>

in subsequent Expense Years, and reimbursed to the Advisor in one or more of
such years, provided that Operating Expenses in any Expense Year, including any
Excess Amount to be paid to the Advisor, shall not exceed the 2%/25% Guidelines.
Within 60 days after the end of any fiscal quarter of the Company for which
total Operating Expenses for the Expense Year exceed the 2%/25% Guidelines,
there shall be sent to the stockholders a written disclosure of such fact,
together with an explanation of the factors the Independent Directors considered
in determining that such excess expenses were justified. Such determination
shall be reflected in the minutes of the meetings of the Board of Directors. The
Company will not reimburse the Advisor or its Affiliates for services for which
the Advisor or its Affiliates are entitled to compensation in the form of a
separate fee. All figures used in the foregoing computation shall be determined
in accordance with generally accepted accounting principles applied on a
consistent basis.

     14.  Other Activities of the Advisor.  Nothing herein contained shall
          -------------------------------
prevent the Advisor from engaging in other activities, including, without
limitation, the rendering of advice to other Persons (including other REITs) and
the management of other programs advised, sponsored or organized by the Advisor
or its Affiliates; nor shall this Agreement limit or restrict the right of any
director, officer, employee, or stockholder of the Advisor or its Affiliates to
engage in any other business or to render services of any kind to any other
partnership, corporation, firm, individual, trust or association. The Advisor
may, with respect to any investment in which the Company is a participant, also
render advice and service to each and every other participant therein. The
Advisor shall report to the Board the existence of any condition or
circumstance, existing or anticipated, of which it has knowledge, which creates
or could create a conflict of interest between the Advisor's obligations to the
Company and its obligations to or its interest in any other partnership,
corporation, firm, individual, trust or association. The Advisor or its
Affiliates shall promptly disclose to the Board knowledge of such condition or
circumstance. If the Sponsor, Advisor, Director or Affiliates thereof have
sponsored other investment programs with similar investment objectives which
have investment funds available at the same time as the Company, it shall be the
duty of the Board (including the Independent Directors) to adopt the method set
forth in the Registration Statement or another reasonable method by which
properties are to be allocated to the competing investment entities and to use
their best efforts to apply such method fairly to the Company.

     The Advisor shall be required to use its best efforts to present a
continuing and suitable investment program to the Company which is consistent
with the investment policies and objectives of the Company, but neither the
Advisor nor any Affiliate of the Advisor shall be obligated generally to present
any particular investment opportunity to the Company even if the opportunity is
of character which, if presented to the Company, could be taken by the Company.
The Advisor or its Affiliates may make such an investment in a property only
after (i) such investment has been offered to the Company and all public
partnerships and other investment entities affiliated with the Company with
funds available for such investment and (ii) such investment is found to be
unsuitable for investment by the Company, such partnerships and investment
entities.

                                       16
<PAGE>

     In the event that the Advisor or its Affiliates is presented with a
potential investment which might be made by the Company and by another
investment entity which the Advisor or its Affiliates advises or manages, the
Advisor shall consider the investment portfolio of each entity, cash flow of
each entity, the effect of the acquisition on the diversification of each
entity's portfolio, rental payments during any renewal period, the estimated
income tax effects of the purchase on each entity, the policies of each entity
relating to leverage, the funds of each entity available for investment and the
length of time such funds have been available for investment. In the event that
an investment opportunity becomes available which is suitable for both the
Company and a public or private entity which the Advisor or its Affiliates are
Affiliated, then the entity which has had the longest period of time elapse
since it was offered an investment opportunity will first be offered the
investment opportunity. The Advisor may consider the property for private
placement only if such property is deemed inappropriate for any investment
entity which is advised or managed by the Advisor, including the Company.

     15.  Relationship of Advisor and Company.  The Company and the Advisor are
          -----------------------------------
not partners or joint venturers with each other, and nothing in this Agreement
shall be construed to make them such partners or joint venturers or impose any
liability as such on either of them.

     16.  Term; Termination of Agreement.  This Agreement shall continue in
          ------------------------------
force until January 29, 2001, subject to an unlimited number of successive one-
year renewals upon mutual consent of the parties. It is the duty of the Board to
evaluate the performance of the Advisor or annually before renewing the
Agreement, and each such renewal shall be for a term of no more than one year.

     17.  Termination by Either Party.  This Agreement may be terminated upon 60
          ---------------------------
days written notice without Cause or penalty, by either party (by a majority of
the Independent Directors of the Company or a majority of the Board of Directors
of the Advisor, as the case may be).

     18.  Assignment to an Affiliate.  This Agreement may be assigned by the
          --------------------------
Advisor to an Affiliate with the approval of a majority of the Board (including
a majority of the Independent Directors). The Advisor may assign any rights to
receive fees or other payments under this Agreement without obtaining the
approval of the Board.  This Agreement shall not be assigned by the Company
without the consent of the Advisor, except in the case of an assignment by the
Company to a corporation or other organization which is a successor to all of
the assets, rights and obligations of the Company, in which case such successor
organization shall be bound hereunder and by the terms of said assignment in the
same manner as the Company is bound by this Agreement.

     19.  Payments to and Duties of Advisor upon Termination.  Payments to the
          --------------------------------------------------
Advisor pursuant to this Section 19 shall be subject to the 2%/25% Guidelines to
the extent applicable.

     (a)  After the Termination Date, the Advisor shall not be entitled to
compensation for further services hereunder except it shall be entitled to
receive from the Company within 30

                                       17
<PAGE>

days after the effective date of such termination all unpaid reimbursements of
expenses and all earned but unpaid fees payable to the Advisor prior to
termination of this Agreement.

     (b)    The Advisor shall promptly upon termination:

     (i)    pay over to the Company all money collected and held for the account
of the Company pursuant to this Agreement, after deducting any accrued
compensation and reimbursement for its expenses to which it is then entitled;

     (ii)   deliver to the Board a full accounting, including a statement
showing all payments collected by it and a statement of all money held by it,
covering the period following the date of the last accounting furnished to the
Board;

     (iii)  deliver to the Board all assets, including Properties, and documents
of the Company then in the custody of the Advisor; and

     (iv)   cooperate with the Company to provide an orderly management
transition.

     20.    Indemnification by the Company. The Company shall indemnify and hold
            ------------------------------
harmless the Advisor and its Affiliates, including their respective officers,
directors, partners and employees, from all liability, claims, damages or losses
arising in the performance of their duties hereunder, and related expenses,
including reasonable attorneys' fees, to the extent such liability, claims,
damages or losses and related expenses are not fully reimbursed by insurance,
subject to any limitations imposed by the laws of the State of Maryland or the
Articles of Incorporation of the Company. Notwithstanding the foregoing, the
Advisor shall not be entitled to indemnification or be held harmless pursuant to
this paragraph 20 for any activity which the Advisor shall be required to
indemnify or hold harmless the Company pursuant to paragraph 21. Any
indemnification of the Advisor may be made only out of the net assets of the
Company and not from Stockholders.

     21.    Indemnification by Advisor.  The Advisor shall indemnify and hold
            --------------------------
harmless the Company from contract or other liability, claims, damages, taxes or
losses and related expenses including attorneys' fees, to the extent that such
liability, claims, damages, taxes or losses and related expenses are not fully
reimbursed by insurance and are incurred by reason of the Advisor's bad faith,
fraud, willful misfeasance, misconduct, negligence or reckless disregard of its
duties, but the Advisor shall not be held responsible for any action of the
Board of Directors in following or declining to follow any advice or
recommendation given by the Advisor.

     22.    Notices.  Any notice, report or other communication required or
            -------
permitted to be given hereunder shall be in writing unless some other method of
giving such notice, report or other communication is required by the Articles of
Incorporation, the Bylaws, or accepted by the party to whom it is given, and
shall be given by being delivered by hand or by overnight mail or other
overnight delivery service to the addresses set forth herein:

writing signed by both parties hereto, or their respective successors or
assignees.

     24.  Severability.  The provisions of this Agreement are independent of and
          ------------
severable from each other, and no provision shall be affected or rendered

understanding among the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements, understandings,
inducements and conditions, express or implied, oral or written, of any nature
whatsoever with respect to the subject matter hereof. The express terms hereof
control and supersede any course of performance and/or usage of the trade
inconsistent with any of the terms hereof. This Agreement may not be modified or
amended other than by an agreement in writing.

     27.  Indulgences, not Waivers.  Neither the failure nor any delay on the
          ------------------------
part of a party to exercise any right, remedy, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any other right, remedy, power or privilege, nor
shall any waiver of any right, remedy, power or privilege with respect to any

     29.  Titles not to Affect Interpretation.  The titles of paragraphs and
          -----------------------------------
subparagraphs contained in this Agreement are for convenience only, and they
neither form a part of this Agreement nor are they to be used in the
construction or interpretation hereof.

     30.  Execution in Counterparts.  This Agreement may be executed in any
          -------------------------

together constitute one and the same instrument. This Agreement shall become
binding when one or more counterparts hereof, individually or taken together,
shall bear the signatures of all of the parties reflected hereon as the
signatories.

     31.  Name.  Wells Capital, Inc. has a proprietary interest in the name
          ----
"Wells." Accordingly, and in recognition of this right, if at any time the
Company ceases to retain Wells Capital, Inc. or an Affiliate thereof to perform
the services of Advisor, the Company will, promptly after receipt of written
request from Wells Capital, Inc., cease to conduct business under or use the
name "Wells" or any diminutive thereof and the Company shall use its best
efforts to change the name of the Company to a name that does not contain the
name "Wells" or any other word or words that might, in the sole discretion of
the Advisor, be susceptible of indication of some form of relationship between
the Company and the Advisor or any Affiliate thereof. Consistent with the
foregoing, it is specifically recognized that the Advisor or one or more of its
Affiliates has in the past and may in the future organize, sponsor or otherwise
permit to exist other investment vehicles (including vehicles for investment in
real estate) and financial and service organizations having "Wells" as a part of
their name, all without the need for any consent (and without the right to
object thereto) by the Company or its Board.

     32.  Initial Investment.  The Advisor has contributed to the Company
          ------------------
$200,000 (the "Initial Investment") in exchange for 20,000 units of limited
partnership interest ("Units") in Wells Operating Partnership, L.P.  The Advisor
or its Affiliates may not sell any of the Units purchased with the Initial
Investment while the Advisor acts in such advisory capacity to the Company,
provided, that such Units may be transferred to Affiliates of the Advisor.  The
--------  ----
restrictions included above shall not apply to any Shares acquired by the
Advisor or its Affiliates other than the Units acquired through the Initial
Investment.  The Advisor shall not vote any Shares it now owns, or hereafter
acquires, in any vote for the election of Directors or any vote regarding the
approval or termination of any contract with the Advisor or any of its
Affiliates.

     bankruptcy, reorganization, or arrangement pursuant to the Federal
     Bankruptcy Act or any similar Federal or state statute, or any proceeding
     instituted for the dissolution or liquidation of Seller.

          (h)  Pre-existing Right to Acquire.  Seller has granted no person or

     owing between Seller and Cinemark, the same shall be adjusted between

to terminate this Agreement by giving written notice of such termination to
Seller, whereupon Purchaser and Seller shall have no further rights,
obligations, or liabilities hereunder, except as may be expressly provided to
the contrary herein; or (ii) Purchaser shall have the right to accept title to
the Property subject to defects and objections with no reduction in the Purchase
Price (except for monetary encumbrances, other than the First Loan Documents,
arising by, through or under Seller), in which event such defects and objections
shall be deemed "Permitted Exceptions;"

                                    Page 11

<PAGE>

or (iii) Purchaser may elect to seek specific performance of this Agreement.
Purchaser shall not be limited with respect to any matters expressly surviving
the closing.

     17.  Condemnation.  If, prior to the Closing, all or any part of the
          ------------
Property is subjected to a bona fide threat of condemnation by a body having the
power of eminent domain or is taken by eminent domain or condemnation (or sale
in lieu thereof), or if Seller has received notice that any condemnation action
or proceeding with respect to the Property is contemplated by a body having the
power of eminent domain, Seller shall give Purchaser immediate written notice of
such threatened or contemplated condemnation or of such taking or sale, and
Purchaser may by written notice to Seller given within thirty (30) days of the
receipt of such notice from Seller, elect to cancel this Agreement. If Purchaser
chooses to cancel this Agreement in accordance with this Paragraph 17, then the
rights, duties, obligations, and liabilities of the parties hereunder shall
immediately terminate and be of no further force and effect. If Purchaser does
not elect to cancel this Agreement in accordance herewith, this Agreement shall
remain in full force and effect and the sale of the Property contemplated by
this Agreement, less any interest taken by eminent domain or condemnation, or
sale in lieu thereof, shall be effected with no further adjustment and without
reduction of the Purchase Price, and at the Closing, Seller shall assign,
transfer, and set over to Purchaser all of the right, title, and interest of
Seller in and to any awards that have been or that may thereafter be made for
such taking.

     18.  Damage or Destruction.  If any of the Improvements shall be destroyed
          ---------------------
or damaged prior to the Closing, and the estimated cost of repair or replacement
exceeds Five Hundred Thousand Dollars ($500,000.00) or if a Lease shall
terminate as a result of such damage, Purchaser may, by written notice given to
Seller within twenty (20) days after receipt of written notice from Seller of
such damage or destruction, elect to terminate this Agreement, in which event,
except as expressly provided herein to the contrary, the rights, duties,
obligations, and liabilities of all parties hereunder shall immediately
terminate and be of no further force or effect. If Purchaser does not elect to
terminate this Agreement pursuant to this Paragraph 18, or has no right to
terminate this Agreement (because the damage or destruction does not exceed
$500,000.00 and the Leases remain in full force and effect), and the sale of the
Property is consummated, Purchaser shall be entitled to receive all insurance
proceeds paid or payable to Seller by reason of such destruction or damage under
the insurance maintained by Seller (less amounts of insurance theretofore
received and applied by Seller to restoration). If the amount of said casualty
or rent loss insurance proceeds is not settled by the date of Closing, Seller
shall execute at Closing all proofs of loss, assignments of claim, and other
similar instruments to ensure that Purchaser shall receive all of Seller's
right, title, and interest in and under said insurance proceeds.

the other that they have not discussed this Agreement or the subject matter
hereof with any real estate broker or agent other than The Roylston Group
("Broker"), which Seller agrees to pay pursuant to a separate agreement, so as
to create any legal right in any such broker or agent to claim a real estate
commission with respect to the conveyance of the Property contemplated by this
Agreement. Seller shall and does hereby indemnify and hold harmless Purchaser
from and against any claim, whether or not meritorious, for any real estate
sales commission, finder's fees, or like compensation in connection with the
sale contemplated hereby and arising out of any act or agreement of Seller.
Likewise, Purchaser shall and does hereby indemnify and hold harmless Seller
