The accompanying unaudited Pro Forma Balance Sheet has been presented as if the
sale of Foxhall had occurred on September 30, 1997. The accompanying unaudited
Pro Forma Statement of Income and Expenses for the nine months ended September
30, 1997 has been presented as if the sales of Foxhall, as well as the three
other properties sold during 1997 (Lakewood Square Shopping Center, Peachtree
Palisades East Office Building and 12621 Featherwood Office Building) had
occurred on December 31, 1996. These four properties are hereafter referred to
as the "Sold Properties". The accompanying unaudited Pro Forma Statement of
Income and Expenses for the year ended December 31, 1996 has been presented as
if the sales of the Sold Properties had occurred on December 31, 1995. In the
opinion of the General Partner, all adjustments necessary to reflect the
financial condition and results of operations of the Partnership exclusive of
the Sold Properties have been made. The unaudited pro forma financial statements
are not necessarily indicative of what the actual financial position and results
of operations would have been had such transactions actually occurred as of
December 31, 1995 and 1996 and September 30, 1997, nor do they purport to
represent the results of operations of the Registrant for future periods.

                    The Earnest Money shall be invested as Seller and Purchaser

                    Seller, the Purchaser shall elect or be deemed to have
                    elected one of the remedies provided for in Section 7(A)
                    below.

          B.   Cash at Closing.  At Closing, Purchaser shall pay to Seller, by
wire transferred current federal funds, an amount equal to the Purchase Price,
minus the Property Market Removal Fee and the sum of the Earnest Money which
Seller receives at Closing from the Escrowee, and plus or minus, as the case may
require, the closing prorations and adjustments to be made pursuant to Section
4(C) below.

     3.   EVIDENCE OF TITLE

          A.   Title Commitment.

               Seller has heretofore delivered to Purchaser a copy of its prior
title insurance policy issued by Safeco Title Insurance Company of Maryland as
Policy No. OM78700 (the "Prior Title Policy"), and Purchaser shall obtain for
itself (and Purchaser may thereafter deliver a copy of same to Prudential
Insurance Company of America ("Purchaser's Mortgage Lender")) and shall cause to
be delivered to Seller, a current commitment in favor of Purchaser for an ALTA
Owner's Title Insurance Policy and Loan Policy (the "Title Commitment"), in the
amount of the Purchase Price, issued by Commonwealth Land Title Insurance
Company (the "Title Insurer"), together with copies of any underlying title
documents disclosed therein. At Closing, the Title Insurer shall deliver to
Purchaser a title policy or a "marked-up" title commitment, dated effective as
of the Closing Date (hereinafter defined), from the Title Insurer in the amount
of the Purchase Price reflecting the conveyance of the Property to Purchaser,
subject only to those exceptions to title which are more fully described on
attached EXHIBIT B and exceptions to title which become Permitted Exceptions
pursuant to this Section 3 (collectively, the "Permitted Exceptions").

          B.   Survey.

               Seller has heretofore delivered to Purchaser a prior survey of
the Real Property prepared by A. Morton Thomas and Associates, Inc., last
revised on May 30, 1984 (the "Prior Survey"). Purchaser shall obtain for itself
(and Purchaser may thereafter deliver a copy of same to Purchaser's Mortgage
Lender) and shall cause to be delivered to Seller and the Title Insurer, a
current survey of the Real Property (the "Survey").

          C.   Review of Title Commitment and Survey.

               If the Title Commitment or Survey disclose exceptions to title
other than those disclosed by the Prior Title Policy, the Prior Survey and the
Permitted Exceptions which are noted on

                                       3
<PAGE>
 
attached EXHIBIT B, then Purchaser shall have until 5:00 p.m. (Chicago, Illinois
time) on the tenth (10th) day after the date of this Agreement within which to
notify Seller of any such exceptions to title to which Purchaser objects. If any
additional exceptions to title arise between the date of the Title Commitment,
the Survey and the Closing, Purchaser shall have five (5) days after its receipt
of notice of same within which to notify Seller of any such exception to title
to which Purchaser objects. Any such exceptions to title not objected to by
Purchaser as aforesaid shall become Permitted Exceptions. If Purchaser objects
to any such exceptions to title, Seller shall have until Closing (but in any
event at least thirty (30) days after it receives notice of Purchaser's
objection(s)) to remove such exceptions to title, which removal may be
accomplished by waiver or endorsement by the Title Insurer. If Seller fails to
remove any such exceptions to title as aforesaid, Purchaser may, as its sole and
exclusive remedy, terminate this Agreement and obtain a return of the Earnest
Money. If Purchaser does not elect to terminate this Agreement, Purchaser shall
consummate the Closing and accept title to the Property subject to all such
exceptions to title (in which event, all such exceptions to title shall be
deemed "Permitted Exceptions"). Notwithstanding anything in this Section 3(C) to
the contrary, Seller shall be obligated, at Closing, to cause the Title Insurer
to remove (by waiver or endorsement) any "Unpermitted Exceptions" (as
hereinafter defined) that are not set forth on EXHIBIT B attached hereto. For
purposes of this Agreement, the term "Unpermitted Exceptions" shall be defined
to mean (i) mortgages and deeds of trust granted by Seller, and (ii) mechanic's
liens with respect to work contracted for by Seller or its authorized agents,
provided that Seller has received written notice of such mechanic's lien prior
to Closing and the cost to remove such mechanic's liens as aforesaid does not
exceed Ten Thousand Dollars ($10,000) in the aggregate.

     4.  CLOSING

          A.   Closing Date.  The "Closing" of the transaction contemplated by

                         but uncollected as of the Closing shall not be
                         adjusted, but Purchaser shall cause the rent and other
                         sums for the period prior to Closing to be remitted to

                         continue to do so for six (6) months thereafter.
                         Purchaser shall promptly remit to Seller any such Past
                         Due Rents paid by tenants set forth on the Closing
                         Delinquency Schedule, but only if (i) a deficiency in
                         the then current rent is not thereby created, and (ii)
                         such Past Due Rents are first applied to any delinquent
                         rents first becoming due and payable subsequent to the
                         Closing Date. To the extent not set forth on the

                         Leases other than Base Rent (such costs and expenses
                         being collectively referred to herein as the "Operating
                         Expenses", and the amounts reimbursable by tenants
                         under the Leases with respect to such Operating
                         Expenses being referred to herein as the "Operating
                         Expense Reimbursements") shall be prorated as follows:
                         the amount of any Base Rents and Operating Expense
                         Reimbursements to be paid by any tenant shall be paid
                         in accordance with such tenant's Lease as now existing
                         (Purchaser hereby covenanting and agreeing not to
                         modify the Leases after Closing to change the date
                         and/or method for payment of such amounts with respect
                         to the period prior to Closing until after the
                         occurrence of the reprorations described in Section
                         4(C)(iii) below) and Purchaser shall, after Closing,
                         promptly pay to Seller a prorata portion of such
                         Operating Expense Reimbursement, based upon
                         apportionment being made as of the Closing Date,
                         promptly after the date when such Operating Expense
                         Reimbursement is received from the tenant;

                    (c)  with respect to tenant improvement costs and/or

                         responsible for a portion of such costs, allowances and
                         commissions based on the ratio of Base Rent payments
                         received by Seller through the Closing Date to the
                         total Base Rent payable over the initial term of the
                         particular New Lease and, in the event that Seller has

                         Contracts;

                    (g)  assignable license and permit fees;

                    (h)  the amount of any merchant association fees held by
                         Seller pursuant to any Lease or New Lease as of the
                         Closing Date (the "Merchant Association Fees"), if any,
                         with Purchaser receiving a credit at Closing against
                         the Purchase Price in the amount of the Merchant
                         Association Fees held by Seller as of the Closing Date,
                         if any; and

                    (i)  other similar items of income and expenses of 
                         operation.

              (ii)  Notwithstanding any other provision of this Section 4(C) but
                    subject to Section 4(C)(iii) below, Seller shall in all
                    events be entitled to retain Operating Expense
                    Reimbursements paid by tenants for real estate taxes and
                    assessments, common area maintenance expenses, utility
                    charges, water and sewer charges, insurance and all other
                    costs and expenses charged to tenants under the Leases as of
                    the Closing.

             (iii)  As soon as practical after Closing, but in no event later
                    than June 30, 1998, Seller and Purchaser shall, with respect
                    to any such amounts prorated or adjusted at Closing pursuant
                    to Section 4(C)(i) above based on estimates or formulae, as
                    applicable, jointly determine and reapportion such amounts
                    in accordance with Section 4(C)(i) above upon
                    determination of the actual costs or expenses with respect
                    thereto.  In the event that the amount credited to Purchaser
                    by Seller at Closing exceeds the amount of the credit that
                    Purchaser should have received had such actual amounts been
                    available at Closing, Purchaser shall promptly remit such
                    excess amount to Seller.  In the event that the amount of
                    Operating Expense Reimbursements retained by Seller at
                    Closing is less than the amount of Operating Expense
                    Reimbursements to which Seller is entitled after calculation
                    of actual Operating Expenses under this Section 4(C),
                    Purchaser shall (x) to the extent such amounts have already
                    been collected by Purchaser from the tenants, promptly remit
                    such amounts to Seller, and (y) to the extent such amounts
                    have not yet been collected from tenants, Purchaser and
                    Seller shall (a) jointly and promptly bill the tenants for
                    such amounts (such bills shall provide that each party's
                    proportionate share thereof be remitted directly to such
                    party, and shall otherwise be in a form reasonably
                    satisfactory to Seller and Purchaser), and (b) diligently
                    pursue collection thereof.  In the event any such
                    proportionate amount is delivered to either Seller or
                    Purchaser contrary to the directions contained in any such
                    bill, then the party receiving such amount shall promptly
                    deliver such sum to the other party.  In the event that:
                    (1) the amount credited to Seller by Purchaser at Closing
                    exceeds the amount of the credit that Seller should have
                    received at Closing had such actual amounts been available
                    at Closing; and/or (2) the amount of the Operating Expense
                    Reimbursements with respect to such amounts retained by
                    Seller at Closing exceed the amount of the Operating Expense
                    Reimbursements that Seller should have retained at Closing
                    had such actual amounts been available at Closing and a
                    portion of such excess amounts are refundable to tenants
                    under any of the Leases, Seller shall, remit such excess
                    amounts to Purchaser; provided that, to the extent any such
                    Operating Expense Reimbursement excess amounts are otherwise
                    payable to tenants owing Past Due Rents, Seller may offset
                    the amounts due to such tenants against the Past Due Rents
                    owing to Seller from such tenants and remit any remaining
                    amounts to Purchaser and Purchaser shall be thereafter
                    obligated to promptly remit such remaining amounts to the
                    particular tenants in question (and Purchaser shall
                    indemnify, defend and hold Seller, its beneficiaries, their
                    partners, and their respective directors, officers,
                    employees and agents, and each of them, harmless from and
                    against any losses, claims, damages and liabilities
                    (including, without limitation, reasonable attorneys' fees
                    and expenses incurred in connection therewith) arising out
                    of or resulting from Purchaser's failure to remit such
                    amounts to the tenants in accordance with this Section
                    4(C)(iii)).

              (iv)  If Seller has not received all Past Due Rents or other
                    amounts owed to it by tenants within sixty (60) days after
                    the Closing Date, Seller at its sole 

                                       9

<PAGE>
 
                    cost and expense, shall be entitled at any time within the
                    twelve (12) month period after such sixty (60) day period
                    (with respect to Past Due Rents) or within the twelve (12)
                    month period after such other amounts are due (with respect
                    to amounts other than Past Due Rents), to commence such
                    actions or proceedings not affecting possession or enforcing
                    landlord's liens or resulting in termination of the Lease in
                    question as Seller shall desire to collect any such Past Due
                    Rents or other amounts, and Purchaser shall cooperate with
                    Seller in any such action.

            (v)     For purposes of this Section 4(C), the amount of any expense
                    credited by one party to the other shall be deemed an
                    expense paid by that party.  The terms and provisions of
                    this Section 4(C) shall survive Closing and the delivery of
                    the Deed.

            (vi)    Seller shall give Purchaser a credit at Closing in the
                    amount of One Hundred Sixty-Seven Thousand Eight Hundred
                    Twenty-Six Dollars ($167,826) for the work allowance
                    provided for in Section VIII.B. (captioned "Substitution
                    Space Allowance") of that certain First Amendment dated
                    February 2, 1997 ("First Amendment"), by and among Robert M.
                    Adrian, M.D., F.A.C.P., an individual, and Craig R.
                    Dufresne, M.D., P.C., jointly and severally, as tenants, and
                    Equity Office Holdings, L.L.C., as agent for Seller.  At
                    Closing Purchaser shall assume the obligations of Seller
                    under that certain contract dated September 12, 1997, by and
                    between Equity Office Properties Management Corp., as agent
                    for the Seller, and The Warren Young Group Inc. (the "Warren
                    Contract"), for the tenant improvement work to be completed
                    in accordance with the First Amendment, and indemnify and
                    hold Seller harmless from and against any claims, losses,
                    liabilities, costs and expenses (including reasonable
                    attorneys' fees) arising out of or in connection with the
                    Warren Contract.

            (viii)  Purchaser acknowledges that prior to the date of this
                    Agreement, Seller has contracted for the installation of one
                    (1) above-ground storage tank on the Real Property pursuant
                    to that certain agreement dated June 2, 1997, with AEG
                    Underground Storage Tank Division.  In the event the work
                    contemplated by such agreement shall be completed prior to
                    Closing, then Seller shall remain responsible for the
                    payments thereunder.  Seller agrees to use its good faith
                    effort to cause such work to be completed prior to Closing.
                    In the event such work has not been completed prior to
                    Closing, then Seller shall give Purchaser a credit at
                    Closing in the amount of the remaining payments to be made
                    thereunder and Purchaser shall assume all of Seller's
                    obligations thereunder and indemnify and hold Seller
                    harmless from and against any claims, losses, liabilities,
                    costs and expenses (including reasonable attorneys' fees)
                    arising out of or in connection with such agreement and/or
                    obligations.

          D.  Transaction Costs.

               Whether or not the closing occurs: (A) Seller shall be
responsible for and pay (i) one-half (1/2) of the District of Columbia Real
Property Transfer Tax and one-half (1/2) of the District of Columbia Deed
Recordation Tax (collectively, the "Transfer Taxes") owed in connection with the
Deed (and Seller and Purchaser shall timely execute and deliver such forms and
returns as are necessary in connection therewith), (ii) all recording charges
for recording any releases or reconveyances of Seller's existing mortgage
financing, if any, and (iii) the fees and costs of its attorneys and advisors;
and (B) Purchaser shall be responsible for and pay (i) one-half of the Transfer
Taxes, (ii) the premium for the owner's title insurance policy to be issued to
Purchaser at Closing (including any and all endorsements), (iii) the Title
Insurer's standard escrow fees, if any, (iv) all recording charges other than
charges for recording any releases or reconveyances of Seller's existing
mortgage financing, if any, (v) the cost of the Survey, and (vi) the fees and
costs of its attorneys and advisors.

          E.  Possession.

               Upon Closing, Seller shall deliver to Purchaser possession of the
Property, subject only to the Permitted Exceptions.

     5.  CASUALTY LOSS AND CONDEMNATION

          If, prior to Closing, the Property or any part thereof shall be taken
or condemned, or destroyed or damaged by fire or other casualty, Seller shall
promptly so notify Purchaser. In such event, provided that either: (i) the
reasonable cost to restore the Property due to such damage or destruction is
greater than Seven Hundred Fifty Thousand and No/100 Dollars ($750,000.00) (a
"Material Casualty"), or (ii) any material portion of the building located on
the Property is taken or condemned, (a "Material Condemnation"), then Purchaser
shall have the option to terminate this Agreement by delivery of its written
termination notice to Seller within fifteen (15) days after Seller's delivery to
Purchaser of its notice of a Material Condemnation or the occurrence of a
Material Casualty. If (a) the aforementioned casualty is not a Material
Casualty, (b) the aforementioned taking or condemnation is not a Material
Condemnation, or (c) Purchaser does not elect to terminate this Agreement
pursuant to the provisions of the preceding sentence (time being of the essence
with respect to any such election), then Seller and Purchaser shall consummate
the transaction contemplated by this Agreement without abatement of the Purchase
Price and Purchaser shall be entitled to approve the terms of any insurance
settlement, such approval not to be unreasonably withheld or delayed, and to
receive at Closing the taking, condemnation or insurance proceeds (or an
assignment of the right to such proceeds) (less any amounts applied against
costs incurred or income lost (solely to the extent Seller has rent loss
insurance proceeds available with respect to such lost income) by Seller as a
result of such occurrence) plus a credit against the Purchase Price in the
amount of any deductible payable by Seller, and Seller shall, at Closing,
execute and deliver to Purchaser all customary proofs of loss, assignments of
claims and other similar items. If Purchaser elects to terminate this Agreement
pursuant to the provisions of this Section 5 and Purchaser is not in default
under this Agreement, the Earnest Money shall be returned to Purchaser by the
Escrowee, in which event this Agreement shall, without further action of the
parties, become null and void and neither party shall have any further rights or
obligations under this Agreement; provided, however, that the foregoing shall
not limit Seller's recourse against Purchaser under Sections 6 and 11(G) below
and under the "Confidentiality Agreement" (as hereinafter defined).

                                      11
<PAGE>
 
     6.  BROKERAGE

          Seller, pursuant to a separate written agreement (the "C&P
Agreement"), is obligated to pay upon Closing (but not otherwise) a brokerage
commission to Cassidy & Pinkard, Inc. ("C&P") for services rendered in
connection with the sale and purchase of the Property. Seller shall indemnify
and hold Purchaser harmless from and against any and all claims of C&P related
to Seller's agreement under the C&P Agreement to pay C&P a commission in
connection with the purchase and sale of the Property, including, without
limitation, reasonable attorneys' fees and expenses incurred by Purchaser in
connection with such claim. Purchaser represents and warrants to Seller that
Purchaser does not have any agreement with any broker or finder in connection
with the Property. Seller and Purchaser shall each indemnify and hold the other
harmless from and against any and all claims of all brokers and finders (other
than a claim by C&P against Seller of the type described in the preceding
sentence, which claim Seller shall be obligated to indemnify Purchaser against
in accordance with the preceding sentence) claiming by, through or under the
indemnifying party and in any way related to the sale and purchase of the
Property, this Agreement or otherwise, including, without limitation, reasonable
attorneys' fees and expenses incurred by the indemnified party in connection
with such claim.

     7.  DEFAULT AND REMEDIES

          A.  Notwithstanding anything to the contrary contained in this
Agreement, if (i) Seller fails to perform in accordance with the terms of this
Agreement, (ii) Purchaser is not otherwise in default hereunder, and (iii) the
Closing does not occur, then, as Purchaser's sole and exclusive remedy hereunder
and at Purchaser's option, either (x) the Earnest Money, or in the event of a
willful default by Seller, the Earnest Money and the Property Market Removal
Fee, shall be returned to Purchaser, in which event this Agreement shall be null
and void, and neither party shall have any rights or obligations under this
Agreement, or (y) upon notice to Seller not less than ten (10) days after
Purchaser becomes aware of such failure, and provided an action is filed within
thirty (30) days thereafter, Purchaser may seek specific performance of this
Agreement, but not damages. Purchaser's failure to seek specific performance as
aforesaid shall constitute its election to proceed under clause (x) above.

          B.  If Purchaser fails to perform in accordance with the terms of this
Agreement and Seller is not in default hereunder, the Earnest Money may be
retained by Seller as liquidated and agreed upon damages and as Seller's sole
and exclusive remedy with respect thereto (in addition to the Property Market
Removal Fee deemed conclusively earned upon the date of this Agreement as
provided in Section 2(A) above); provided, however, that the foregoing shall not
limit Seller's recourse against Purchaser under Section 6 above, Section 11(G)
below and under the Confidentiality Agreement. PURCHASER AND SELLER ACKNOWLEDGE
AND AGREE THAT (1) THE EARNEST MONEY IS A REASONABLE ESTIMATE OF AND BEARS A
REASONABLE RELATIONSHIP TO THE DAMAGES THAT WOULD BE SUFFERED AND COSTS INCURRED
BY SELLER AS A RESULT OF HAVING WITHDRAWN THE PROPERTY FROM SALE AND THE FAILURE
OF CLOSING TO OCCUR DUE TO A DEFAULT OF PURCHASER UNDER THIS AGREEMENT; (2) THE
ACTUAL DAMAGES SUFFERED AND COSTS INCURRED BY SELLER AS A RESULT OF SUCH
WITHDRAWAL AND FAILURE TO CLOSE DUE TO A DEFAULT OF PURCHASER UNDER THIS
AGREEMENT WOULD BE EXTREMELY DIFFICULT AND IMPRACTICAL TO DETERMINE; (3)
PURCHASER SEEKS TO LIMIT ITS LIABILITY UNDER THIS AGREEMENT TO THE AMOUNT OF THE
EARNEST MONEY IN THE EVENT THIS AGREEMENT IS TERMINATED AND THE TRANSACTION
CONTEMPLATED BY THIS AGREEMENT DOES NOT CLOSE DUE TO A DEFAULT OF

                                      12
<PAGE>
 
PURCHASER UNDER THIS AGREEMENT; AND (4) THE EARNEST MONEY SHALL BE AND
CONSTITUTE VALID LIQUIDATED DAMAGES.



PURCHASER INITIALS:                                          SELLER INITIALS:


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

          C.  After Closing, Seller and Purchaser shall, subject to the terms
and conditions of this Agreement, have such rights and remedies as are available
at law or in equity, except that neither Seller nor Purchaser shall be entitled
to recover from the other consequential or special damages.

     8.  CONDITIONS PRECEDENT

          A.  Subject to Section 11(G) below and the provisions of that certain
confidentiality letter agreement dated May 29, 1997 by and between C&P, on
behalf of Seller, and Purchaser, as amended by that certain modification letter
agreement dated August 19, 1997 by and between Equity Office Properties
Management Corp., a Delaware corporation, on behalf of Seller, and Purchaser
(collectively the "Confidentiality Agreement"), Purchaser acknowledges that,
prior to the date hereof, it has had an opportunity to inspect the Property,
review the Leases, the Service Contracts, all "Disclosures" (as hereinafter
defined) provided by Seller and make such other inquiries and investigations and
obtain such reports and analyses it deemed adequate in connection with its
decision to purchase the Property, and, as a result thereof, Purchaser agrees
that, except as specifically set forth in this Agreement, it shall purchase the
Property in its "AS IS, WHERE IS" condition, subject to ordinary wear and tear
and as more particularly provided in Sections 8(B)(i), 11(H) and 11(L)(4) below.

          B.  The obligation of Purchaser to consummate the transaction
hereunder shall be subject to the fulfillment on or before the Closing Date of
all of the following conditions any or all of which may be waived by Purchaser
in its sole discretion:

          (i)  The Property shall be in substantially the same condition as it
     was as of the date of this Agreement, subject to ordinary wear and tear and
     the acts (both prior and subsequent to the date of this Agreement) of
     Purchaser, or any of its agents, representatives, employees or contractors.
     For purposes of this Section 8(B)(i), an item or items shall be deemed
     "ordinary wear and tear" if the cost to replace or repair such items so
     they are in substantially the same condition as of the date of this
     Agreement is less than (i) Ten Thousand Dollars ($10,000) per item, and
     (ii) Fifty Thousand Dollars ($50,000) for all items. In the event such
     items are not of an "ordinary wear and tear" nature (that is to say, such
     items exceed the cost of the threshold dollar amounts above), then Seller
     is under no obligation to repair such items or to give Purchaser any credit
     for such items at Closing. In the event such items are of an "ordinary wear
     and tear" nature, then Seller, at Seller's sole and absolute discretion,
     shall either (1) replace or repair such items so they are in substantially
     the same condition as of the date of this Agreement, or (2) give Purchaser
     a credit at Closing in an amount sufficient to replace or repair such items
     to such a condition.

          (ii)  All of the representations and warranties of Seller contained in
     Section 10(A) of this Agreement shall be true and correct in all material
     respects as of the Closing Date (with

                                      13
<PAGE>
 
     appropriate modifications permitted or deemed made under Section 10 of this
     Agreement or not adverse to Purchaser).

          (iii)  Seller shall have performed and observed, in all material
     respects, all covenants and agreements of this Agreement to be performed
     and observed by Seller as of the Closing Date.

          C.  The obligation of Seller to consummate the transaction hereunder
shall be subject to the fulfillment on or before the Closing Date of all of the
following conditions, any or all of which may be waived by Seller in its sole
discretion:

          (i)    Escrowee shall have received the Purchase Price as adjusted
     pursuant to and payable in the manner provided for in this Agreement.

          (ii)   All of the representations and warranties of Purchaser
     contained in Section 11(T) of this Agreement shall be true and correct in
     all material respects as of the Closing Date.

          (iii)  Purchaser shall have performed and observed, in all material
     respects, all covenants and agreements of this Agreement to be performed
     and observed by Purchaser as of the Closing Date.

     9.  ESTOPPEL CERTIFICATES

          A.  Seller shall, within five (5) business days of the date of this
Agreement, send estoppel certificates (individually, an "Estoppel Certificate"
and collectively, the "Estoppel Certificates") to each tenant occupying space at
the Property as of the date of this Agreement. The Estoppel Certificates shall
be in the form of EXHIBIT G attached hereto (the "Form Tenant Estoppel
Certificate").

          B.  It shall be a condition precedent to Purchaser's obligation to
purchase the Property pursuant to this Agreement that Seller provide to
Purchaser, at Closing, Estoppel Certificates executed by tenants occupying not
less than seventy percent (70%) of the net rentable square footage of space at
the Property as of the date of this Agreement. The Estoppel Certificates
executed by tenants shall be in substantially the form of the Form Tenant
Estoppel Certificate, except that an Estoppel Certificate shall be deemed an
acceptable Estoppel Certificate for purposes of this Section 9 if it contains
the information set forth on EXHIBIT G, and/or the qualification by the tenant
of any statement as being to the best of its knowledge or as being subject to
any similar qualification, and/or any tenant failure to address or certify the
Estoppel Certificate to Purchaser's Mortgage Lender (the aforesaid acceptable
forms of Estoppel Certificates to be delivered are collectively referred to as
the "Required Estoppel Certificates"). During the period prior to Closing,
Seller agrees to use its good faith efforts to obtain the Required Estoppel
Certificates, and, once the Required Estoppel Certificates are obtained, to
continue to use its good faith efforts to obtain Estoppel Certificates from the
remaining tenants.

     C.  [Intentionally deleted]

     D.  In the event that Seller is unable to provide to Purchaser the Required
Estoppel Certificates at Closing, Purchaser may either: (x) elect not to
purchase the Property, in which event this Agreement shall be null and void, the
Escrowee shall promptly return the Earnest Money to Purchaser and thereafter
neither Seller nor Purchaser shall have any further rights or obligations under
this Agreement, provided, however, that the foregoing shall not limit Seller's
recourse against Purchaser

                                      14

under Section 6 above and Section 11(G) below and under the Confidentiality
Agreement; or (y) elect to purchase the Property notwithstanding Seller's
inability to provide the Required Estoppel Certificates, in which event Seller
shall not be obligated to provide any additional Estoppel Certificates to
Purchaser after Closing.

          E.   If any Estoppel Certificates contain statements or allegations
that a default or potential default exists on the part of Seller under the Lease
in question and (i) the existence or the substance of such allegations or
statements were contained in any "Disclosures" (as defined in Section 11(H)
below) prior to the date of this Agreement, or (ii) prior to the date of this
Agreement Purchaser otherwise obtained actual knowledge of facts revealing the
substance of such statements or allegations, (iii) Seller otherwise disclosed in
writing the existence or the substance of such allegations or statements prior
to the date of this Agreement, or (iv) Purchaser elects that Closing occur
notwithstanding the existence of such default or potential default, then such
Estoppel Certificates shall be deemed acceptable for purposes of this Section 9,
notwithstanding the existence of such allegations or statements and Seller shall
have no liability to Purchaser hereunder with respect to the existence of such
allegations, statements or information.

     10.  SELLER'S REPRESENTATIONS AND WARRANTIES

          A.   Seller represents and warrants to Purchaser the following:

               (i)    As of the date of this Agreement, to the "Actual Knowledge
                      of Seller" (as hereinafter defined), except as set forth
                      on EXHIBIT H attached hereto, Seller has received no
                      written notice from any governmental authority of any
                      material violation of any, state or federal law, rule or
                      regulation concerning the Property or any part thereof
                      which has not been cured prior to the date of this
                      Agreement; provided, however, that Seller makes no
                      representation or warranty with respect to (A) the
                      information or matters disclosed in the items set forth in
                      EXHIBIT P attached hereto, and (B) the Property's
                      compliance with the American with Disabilities Act.

               (ii)   The list attached hereto as EXHIBIT C lists all of the
                      Service Contracts, the service provided thereunder, the
                      vendor under each Service Contract and, if such Service
                      Contract is written, the date of such Service Contract.

               (iii)  Except as set forth on EXHIBIT I attached hereto, as of
                      the date of this Agreement, Seller has received no written
                      notice of (a) any pending litigation with respect to the
                      Property which would affect the Property after Closing, or
                      (b) any proposed modification from a governmental body
                      authorized to change the Property's existing zoning to a
                      classification that would not permit the present use of
                      the Property after Closing.

               (iv)   Seller has been duly organized and is validly existing
                      under the laws of Florida and is in good standing in the
                      District of Columbia. Seller has the full right and
                      authority to enter into this Agreement and to consummate
                      or cause to be consummated the transactions contemplated
                      herein to be made

                                      15

                      by Seller.  The person signing this Agreement on behalf of
                      Seller is authorized to do so.

               (v)    Attached hereto as EXHIBIT T is a list (the "Rent Roll")
                      setting forth, to the Actual Knowledge of Seller, the
                      following information as of the date of this Agreement
                      (or, such other date as may be noted below): (1) the name
                      of each tenant under each of the Leases as of the date of
                      this Agreement, (2) a description of the space occupied by
                      each tenant, (3) the monthly Base Rent and Operating
                      Expense Reimbursements billed to each tenant with respect
                      to the month of August, 1997, (4) the approximate square
                      footage demised under the particular tenant's Lease, (5)
                      the "base year" for payment of real estate tax pass-
                      throughs, (6) the "base year" for payment of all other
                      Operating Expense Reimbursements other than real estate
                      taxes, and (7) the amount of all unapplied Security
                      Deposits held by Seller with respect to the Leases.

               (vi)   To the Actual Knowledge of Seller, prior to the date of
                      this Agreement, Seller has delivered to Purchaser true and
                      correct copies of the Leases.

          B.  When used in this Agreement, the term "Actual Knowledge of Seller"
shall mean and be limited to the actual (and not imputed, implied or
constructive) current knowledge of Alissa Schneider, Director - Dispositions of
Equity Office Properties Management Corp., a Delaware corporation ("EOPMC"), and
Christopher P. Mundy, Vice President of EOPMC. Notwithstanding anything herein
to the contrary, neither Alissa Schneider nor Christopher P. Mundy shall have
any personal liability or liability whatsoever with respect to any matters set
forth in this Agreement or any of Seller's representations and/or warranties
herein being or becoming untrue, inaccurate or incomplete in any respect.

          C.  The representations and warranties set forth in this Section 10
shall, subject to Section 10(F), be deemed to be remade as of Closing and shall
survive the Closing and the delivery of the Deed for a period of one hundred
eighty (180) days from the Closing Date. Notice of any claim as to a breach of
any such representations or warranties must be made to Seller prior to the
expiration of such one hundred eighty (180) day period or it shall be deemed a
waiver of the right to assert such claim.

          D.  Seller does not represent and warrant that any particular Service
Contract will be in force or effect as of the Closing or that tenants under
Leases or the parties to the Service Contracts will not be in default under
their respective Leases or Service Contracts, and neither the existence of any
default by any tenant under its Lease nor the default of any party under any
Service Contract shall affect the obligations of Purchaser hereunder; provided,
however, the foregoing shall not affect the conditions contained in Sections 8
and 9 above.

          E.  As and to the extent that Seller and Purchaser or its
representatives have reviewed any Disclosures prior to the date of this
Agreement and such documents or materials contain information inconsistent with
or different from the representations and warranties set forth in Section 10(A)
above, or prior to the date of this Agreement Purchaser otherwise obtained
actual knowledge of facts or Seller otherwise disclosed in writing to Purchaser
facts that are inconsistent with or different from the representations and
warranties made in Section 10(A), then such representations and warranties are
hereby deemed modified to conform them to the information set forth in such
documents and materials or to such other facts.

                                      16
<PAGE>
 
          F.  As and to the extent that (i) Purchaser obtains actual knowledge
of facts, or (ii) any Estoppel Certificates or other documents with respect to
Leases and/or matters addressed by Section 10(A) contain information or facts
that are inconsistent with or different from the representations and warranties
made in Section 10(A), are received by Purchaser or received by Seller and
delivered to Purchaser prior to the Closing, and the Closing occurs, then the
representations and warranties in Section 10(A) shall be deemed to be modified
and/or superseded by such certificates or other documents (and, in such event,
Seller shall no longer have any liability hereunder with respect to the portion
of the representation or warranty superseded herein, as applicable); provided,
however, the foregoing shall not affect the conditions contained in Section 9
above. In addition, in the event that an Estoppel Certificate is received from a
tenant (before or after Closing) which confirms the accuracy of the
representations and warranties made in Section 10(A), then the representations
and warranties in Section 10(A) shall be deemed to be superseded by such
Estoppel Certificate (and, in such event, Seller shall no longer have any
liability hereunder with respect to the portion of the representation or
warranty superseded).

     11.  MISCELLANEOUS

          A.  All understandings and agreements heretofore had between Seller
and Purchaser with respect to the Property are merged in this Agreement, which
alone fully and completely expresses the agreement of the parties. Purchaser
further acknowledges that, except as expressly provided in this Agreement,
neither Seller nor any agent or representative of Seller has made, and Seller is
not liable for or bound in any manner by, any express or implied warranties,
guaranties, promises, statements, inducements, representations or information
pertaining to the Property.

          B.  Except for an assignment to the "Permitted Assignee" (as
hereinafter defined), neither this Agreement nor any interest hereunder shall be
assigned or transferred by Purchaser without the written consent of Seller,
which consent may be withheld in the sole and absolute discretion of Seller. For
purposes of this Agreement, the term "Permitted Assignee" shall be defined to
mean Columbia Realty Venture, a District of Columbia limited partnership, a
general partner of which is Joshua B. Bernstein. Upon an assignment to the
Permitted Assignee, the Permitted Assignee shall execute and deliver an
agreement to Seller in which the Permitted Assignee assumes all of the
obligations of Purchaser under this Agreement. Upon an assignment of this
Agreement to the Permitted Assignee: (1) Purchaser shall not be relieved of any
subsequently accruing liability under this Agreement, and (2) as used in this
Agreement, the "Purchaser" shall be deemed to include the Permitted Assignee.
Seller may assign or otherwise transfer its interest under this Agreement. As
used in this Agreement, the term "Seller" shall be deemed to include any
assignee or other transferee of any Seller. Upon any such transfer by a Seller,
such Seller shall be relieved of any subsequently accruing liability under this
Agreement. Subject to the foregoing, this Agreement shall inure to the benefit
of and shall be binding upon Seller and Purchaser and their respective
successors and assigns.

          C.  This Agreement shall not be modified or amended except in a
written document signed by Seller and Purchaser.

          D.  Time is of the essence of this Agreement.

          E.  This Agreement shall be governed and interpreted in accordance
with the laws of the District of Columbia.

          G.  Notwithstanding anything to the contrary contained in this
Agreement, Purchaser shall indemnify and hold Seller and its employees and
agents, and each of them, harmless from and against any and all losses, claims,
damages and liabilities (including, without limitation, reasonable attorneys'
fees incurred in connection therewith) arising out of or resulting from
Purchaser's inspection of the Property prior to the date of this Agreement
(including, without limitation, any entry upon or inspection of the Property
made by Purchaser in violation of the terms, conditions and provisions of the
Letter of Intent and Confidentiality Agreement pertaining thereto); provided
that, Purchaser shall not be liable for matters discovered as a result of such
studies. Except upon the written request of Seller pursuant to Section 11(K)
below, Purchaser shall not advise Seller of the results, or deliver to Seller
copies, of any of the studies, reports, surveys or other information, data
and/or documents relating to the Property or any part thereof prepared by or at
the request of Purchaser, its employees, agents, representatives or contractors.
The provisions of this Section 11(G) shall survive the Closing or other
termination of this Agreement.

          H.  Acknowledging the prior use of the Property and Purchaser's
opportunity to inspect the Property and except as specifically provided in this
Agreement, Purchaser agrees to take the Property "as is" with all faults and
conditions thereon. Any information, reports, statements, documents or records,
including, without limitation, the items set forth in EXHIBIT P (collectively,
the "Disclosures") provided or made to Purchaser or its constituents by Seller,
its agents, employees, contractors or representatives, concerning the Property
shall not be representations or warranties. Purchaser shall not rely on such
Disclosures, except as set forth herein, but rather, Purchaser shall rely only
on its own inspection of the Property. PURCHASER ACKNOWLEDGES AND AGREES THAT,
EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, NEITHER SELLER NOR ITS AGENTS,
EMPLOYEES, CONTRACTORS OR REPRESENTATIVE HAS MADE, AND NONE OF THEM MAKES AND
EACH SPECIFICALLY DISCLAIMS ANY STATEMENTS, REPRESENTATIONS, WARRANTIES,
PROMISES, COVENANTS, AGREEMENTS OR GUARANTIES OF ANY KIND OR CHARACTER
WHATSOEVER, WHETHER EXPRESS OR IMPLIED, ORAL OR WRITTEN, PAST, PRESENT OR
FUTURE, OF, AS TO, CONCERNING OR WITH RESPECT TO (A) THE NATURE, QUALITY OR
CONDITION OF THE PROPERTY, INCLUDING, WITHOUT

                                      19
<PAGE>
 
LIMITATION, THE WATER, SOIL AND GEOLOGY, (B) THE INCOME HERETOFORE DERIVED OR TO
BE DERIVED FROM THE PROPERTY, (C) THE SUITABILITY OF THE PROPERTY FOR ANY AND
ALL ACTIVITIES AND USES WHICH PURCHASER MAY CONDUCT THEREON, (D) THE COMPLIANCE
OF OR BY THE PROPERTY OR ITS OPERATION WITH ANY LAWS, RULES, ORDINANCES OR
REGULATIONS OF ANY APPLICABLE GOVERNMENTAL AUTHORITY OR BODY, (E) THE
HABITABILITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE
PROPERTY, OR (F) ANY OTHER MATTER WITH RESPECT TO THE PROPERTY, AND SPECIFICALLY
DISCLAIM ANY REPRESENTATIONS REGARDING TERMITES OR WASTES, AS DEFINED BY THE
U.S. ENVIRONMENTAL PROTECTION AGENCY REGULATIONS AT 40 C.F.R., OR ANY HAZARDOUS
SUBSTANCE, AS DEFINED BY THE COMPREHENSIVE ENVIRONMENTAL RESPONSE COMPENSATION
AND LIABILITY ACT OF 1980 ("CERCLA"), AS AMENDED, AND REGULATIONS PROMULGATED
THEREUNDER.

               Purchaser, its successors and assigns, hereby waive, release and
agree not to make any claim or bring any cost recovery action or claim for
contribution, indemnity or other action or claim against Seller or its
affiliates, directors, officers, employees, agents, attorneys, or assigns
(collectively, "Seller and its Affiliates") (a) under any federal, state, or
local environmental or health and safety law or regulation, including CERCLA or
any state equivalent, or any similar law now existing or hereafter enacted, (b)
with respect to, in connection with or resulting from any discharge, disposal,
release, or escape of any chemical, or any hazardous or toxic material
whatsoever, on, at, to, or from the Property; or (c) any environmental
conditions whatsoever on, under, or in the vicinity of the Property.

          I.  In any lawsuit or other proceeding under or with respect to this
Agreement, Purchaser and Seller waive any rights they may have to trial by jury.

          J.  Purchaser acknowledges that all information with respect to the
Property furnished or to be furnished to Purchaser is, has been and will be so
furnished on the condition that Purchaser maintain the confidentiality thereof.
Accordingly, Purchaser shall, and shall cause its directors, officers and other
personnel and representatives to, hold in strict confidence, and not disclose to
any other party without the prior written consent of Seller: (i) any of the
information with respect to the Property delivered to Purchaser by Seller or any
of its agents, representatives or employees, or (ii) the existence of this
Agreement or any term or condition thereof, or (iii) the results of any
inspections or studies undertaken in connection herewith. In addition, neither
Purchaser nor Purchaser's directors, officers and other personnel and
representatives shall solicit offers to purchase the Property to any other party
without the prior written consent of Seller. Notwithstanding the above,
Purchaser may disclose such information to individuals or entities necessary for
Purchaser to consummate the transaction contemplated herein (such as lenders,
engineers, prospective management companies, environmental consultants,
accountants and tax advisors) and as required by law. Purchaser shall, with
respect to any parties to whom the existence of this Agreement or any
information with respect to the Property is disclosed, notify such parties of
the existence of the Confidentiality Agreement and its applicability to any such
information provided to any such parties. In the event the Closing does not
occur and this Agreement is terminated, Purchaser shall, upon written request by
Seller, promptly return to Seller all copies of all such information without
retaining any copy thereof or extract therefrom. Purchaser's obligations under
this Section 11(J) shall expire upon and not survive the Closing.

          K.  If for any reason Purchaser does not consummate the Closing, then
Purchaser shall, upon Seller's written request, assign and transfer to Seller
all of its right, title and interest in and to 

                                      20
<PAGE>
 
any and all studies, reports, surveys and other information, data and/or
documents relating to the Property or any part thereof prepared by or at the
request of Purchaser, its employees and agents, other than economic and market
analyses, and shall deliver to Seller copies of all of the foregoing.

          L.   Seller and Purchaser further agree as follows:

               1.   From and after August 19, 1997 through the Closing, Seller
          has delivered or shall deliver, as applicable, for Purchaser's review
          (a "New Lease Notice"), a copy of any proposed new Lease, or any
          modification, amendment, restatement or renewal of any existing Lease
          (individually, a "New Lease" and collectively, "New Leases") together
          with copies of any information submitted by the prospective tenant to
          Seller with respect to such New Lease. In addition, Seller shall also
          submit to Purchaser for Purchaser's review a summary of any leasing or
          brokerage commissions payable in connection with such New Lease and,
          if a written agreement exists between Seller and the leasing broker
          entitled to be paid a commission in connection with such New Lease and
          Seller has a copy of same, a copy of such written agreement. During
          the period between the date of this Agreement and Closing, Purchaser
          shall have the right to approve or disapprove of any New Lease and any
          related costs that would be incurred by the landlord under such New
          Lease, such as leasing/brokerage commissions, rent abatements,
          construction or buildout costs and construction allowances, by
          responding in writing to Seller's New Lease Notice within five (5)
          days after Purchaser's receipt of the New Lease Notice. If Purchaser
          fails to approve or disapprove of such New Lease within such five (5)
          day period, Purchaser shall be deemed to have conclusively approved of
          such New Lease and all such related costs. Seller and Purchaser hereby
          acknowledge that during the period from and after August 19, 1997
          through the date of this Agreement, New Leases have been entered into
          with the following tenants: (a) David R. Curfman, (b) RVI, Inc. t/a
          Pamela Barkley, and (c) Treetop Toys, Inc.

               2.   All tenant improvement costs and/or allowances and leasing
          commissions relating to (a) New Leases entered into by Seller during
          the period between August 19, 1997 and the date of this Agreement, and
          (b) New Leases entered into by Seller after the date of this Agreement
          which Purchaser approves (or is deemed to approve) in accordance with
          Section 11(L)(1) above, shall be allocated or prorated in accordance
          with Section 4(C)(i)(c) above. In addition, should the timing and
          scope of work to be performed by the lessor under such New Leases
          require Seller to enter into contracts with contractors or other
          parties prior to Closing in order to comply with the lessor's
          obligations under such New Leases, Seller shall submit the proposed
          contract with such contractor or other parties to Purchaser for its
          approval (not to be unreasonably withheld or delayed). If Purchaser
          fails to approve or disapprove of such contract within five (5) days
          after its receipt of same, Purchaser shall be deemed to have
          conclusively approved of such contract, and shall assume such contract
          as of the Closing Date. If such contract results in work for which the
          provider or subcontractor thereunder may obtain a lien against the
          Property if such work is not paid for, then the "Permitted Exceptions"
          shall be deemed to include any potential liens and related notices of
          commencement as a result thereof.

               3.   From and after the date of this Agreement through the
          Closing, Seller shall deliver for Purchaser's review (a "New Service
          Contract Notice"), a copy of any proposed new Service Contract, or any
          modification, amendment, restatement or renewal

                                      21

          of any existing Service Contract (individually, a "New Service
          Contract" and collectively, "New Service Contracts"). During the
          period between the date of this Agreement and Closing, Purchaser shall
          have the right to approve or disapprove of any New Service Contract by
          responding in writing to Seller's New Service Contract Notice within
          five (5) days after Purchaser's receipt of the New Service Contract
          Notice; provided that, Purchaser's approval shall not be unreasonably
          withheld or delayed. If Purchaser fails to approve or disapprove of
          such New Service Contract within such five (5) day period, Purchaser
          shall be deemed to have conclusively approved of such New Service
          Contract.

               4.   Seller shall maintain its current insurance policies
          covering the Property at the same levels from and after the date of
          this Agreement until the Closing, and shall operate and maintain the
          Property in a manner consistent with the manner in which Seller has
          operated and maintained the Property prior to the date of this
          Agreement; provided that, nothing in this Agreement shall require
          Seller to (y) repair or replace any items with respect to the Property
          which are deemed not to be "ordinary wear and tear" pursuant to
          Section 8(B)(i) above, or (z) commence any lease negotiations with
          tenants, prospective or otherwise, unless in connection with extending
          the term of a Lease which will expire prior to Closing.

               5.   Seller shall not apply any Security Deposits without first
          obtaining the Purchaser's prior written consent.

          M.  Seller and Purchaser hereby designate Escrowee to act as and
perform the duties and obligations of the "reporting person" with respect to the
transaction contemplated by this Agreement for purposes of 26 C.F.R. Section
1.6045-4(e)(5) relating to the requirements for information reporting on real
estate transaction closed on or after January 1, 1991. In this regard, Seller

reporting person with respect to the transaction contemplated by this Agreement.

          N.  This Agreement may be executed in any number of identical

the parties but all of which taken together shall constitute a single
instrument.

          O.  Seller and Purchaser acknowledge and agree that neither this
Agreement nor a memorandum thereof shall be recorded against the Property.

          P.  Purchaser acknowledges and agrees that any recovery against Seller

action that Purchaser may have against Seller with respect to this Agreement and
the transactions contemplated herein shall only be recoverable against Seller in
an amount not in excess of One Million Dollars ($1,000,000.00).

          Q.  In the event of a conflict between the terms and provisions of the
Confidentiality Agreement and this Agreement, the terms and provisions of this

          R.  Except as specifically provided for herein, the representations,
warranties,  covenants and agreements of Seller set forth in this Agreement

          S.  Except as specifically provided herein, no third parties shall

                     requisite action necessary to authorize Purchaser to enter
                     into this Agreement and to carry out its obligations
                     hereunder have been, or by the Closing will have been,
                     taken. The person signing this Agreement on behalf of
                     Purchaser is authorized to do so.

               (ii)  There is no action, suit, arbitration, unsatisfied order or
                     judgment, government investigation or proceeding pending
                     against Purchaser which, if adversely determined, could
                     individually or in the aggregate materially interfere with
                     the consummation of the transaction contemplated by this
                     Agreement.

The sum of Two Hundred Fifty Thousand Dollars ($250,000) (together with any
interest accrued thereon, the "Initial Deposit") was deposited with you in
escrow on August 19, 1997 on behalf of Bernstein Management Corporation, a
District of Columbia corporation ("BMC"), and Equity Office Properties
Management Corp., a Delaware corporation ("EOPMC"), on behalf of the "Seller"
(defined below), who is the owner of the property commonly known as Foxhall

held in accordance with the terms of that certain letter of intent dated August
19, 1997 between BMC and EOPMC, on behalf of the owner as aforesaid. A portion
of the Initial Deposit in the amount of Fifty Thousand Dollars ($50,000) plus
any accrued interest thereon is hereinafter referred to as the "Property Market
Removal Fee".

The additional sum of Seven Hundred Fifty Thousand Dollars ($750,000.00) (the
"Additional Deposit") is now deposited with you in escrow on behalf of BMC as
the "Purchaser" under that certain Real Estate Sale Agreement (the "Contract"),
dated ____________, 1997 with First Capital Institutional Real Estate, Ltd. - 1,
a Florida limited partnership, and First Capital Institutional Real Estate, 
Ltd. - 2, a Florida limited partnership, collectively, the "Seller", with 
respect to the purchase and sale of the Property. The Initial Deposit (less the
Property Market Removal Fee) and the Additional Deposit, together with any
accrued interest thereon, is hereinafter referred to as the "Escrow Deposit".

As escrowee, you are hereby directed to hold, deal with and dispose of the
Property Market Removal Fee and the Escrow Deposit in accordance with the
following terms and conditions:

1.   Upon the execution of this Joint Order Escrow Agreement, you are to
     promptly wire transfer, in current federal funds, the Property Market
     Removal Fee to Seller pursuant to the following wiring instructions:
     __________________________________________.

2.   You are to hold the Escrow Deposit until: (a) you are in receipt of a joint
     order by the undersigned Seller and Purchaser as to the disposition of the
     Escrow Deposit; or (b) you are in receipt of a written demand (the
     "Demand") from either Seller or Purchaser for the payment of the Escrow
     Deposit or any portion thereof. Upon receipt of any Demand, you are
     directed to so notify the non-demanding party, enclosing a copy of the
     Demand. If within five (5) business days after the non-demanding party has
     received or is deemed to have received your notice of your receipt of the
     Demand, you have not received from the non-demanding party its notice of
<PAGE>
 
     objection to the Demand, then you are to disburse the Escrow Deposit as
     requested by the Demand. If within said five business-day period you
     receive from the non-demanding party its notice of objection to the Demand,
     then you are to continue to hold the Escrow Deposit until you are in
     receipt of a joint order as aforesaid, but after sixty (60) days you may
     deposit the Escrow Deposit with a Court of competent jurisdiction.

3.   Notwithstanding the foregoing, as escrowee, you are hereby expressly
     authorized to comply with and obey any and all orders, judgments or decrees
     entered or issued by any Court, and in case you obey or comply with any
     such order, judgment or decree of any Court, you shall not be liable to
     either of the parties hereto or any other person or entity by reason of
     such compliance, notwithstanding any such order, judgment or decree be
     entered without jurisdiction or be subsequently reversed, modified,
     annulled, set aside or vacated. In case of any suit or proceeding regarding
     these Escrow Instructions, to which you are or may at any time be a party,
     the undersigned Seller and Purchaser agree that the non-prevailing party
     shall pay to you upon demand all reasonable costs and expenses incurred by
     you in connection herewith but solely for costs incurred in your role as
     Escrowee.

4.   You shall not charge an escrow fee in connection with your role as Escrowee
     hereunder.

5.   As escrowee, you shall invest the Escrow Deposit in an interest-bearing
     account with a federally-insured bank or savings and loan as association or
     as otherwise directed by both Purchaser and Seller in writing. Any interest
     earned on the Escrow Deposit, after you deduct your customary investment
     charges, if any, shall become and be deemed to be a part of the Escrow
     Deposit. The FEIN of Purchaser is ____________________.

Ladies and Gentlemen:

     As you know, the Occupational Safety and Health Administration ("OSHA") has
enacted regulations (the "OSHA Regulations") which require building owners to
provide information regarding the presence, location and quantity of asbestos

occupants, including employers of employees who lease space within the owner's
building. In addition, the OSHA Regulations, specifically 29 C.F.R.
(S)1910.1001(j)(2)(ii) and 29 C.F.R. (S)1926.1101(n)(6), require building owners
to keep records of all information required to be maintained by the OSHA
Regulations and to transmit such records to subsequent owners at or before the
time of closing.

partnership, and First Capital Institutional Real Estate, Ltd. - 2, a Florida

letter, provided Columbia Realty Venture, a District of Columbia limited
partnership ("Purchaser") with copies of information required to be maintained
and transmitted as described above regarding ACM and PACM at the property

sampling results and reports in our possession (such information, notices and
reports being referred to herein collectively as the "Reports"). A list of such
Reports is set forth on SCHEDULE 1 attached hereto.

     The undersigned makes no representation, warranty, promises, covenants,
agreements or guarantees of any kind or character whatsoever, express or
implied, oral or written, past, present or future, of, as to, concerning or with
respect to the information and documentation transmitted herewith including
