     NOW, THEREFORE, in consideration of the mutual undertakings and covenants
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Transferor Corporation and the
BRI Partnership hereby covenant and agree as follows:

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE


                                      -2-


     1.01   Agreement to Contribute; Assignment. The Transferor Corporation
            shall contribute to the BRI Partnership, and the BRI Partnership
            shall accept from the Transferor Corporation, in exchange for BRI
            Partnership Units and upon the terms and conditions set forth in
            this Agreement, the Property. At the Closing (as defined in Section
            3.01), the Transferor Corporation shall, contribute, assign,
            transfer and deliver the Property to the BRI Partnership, or its
            designees as provided in Section 18.01 hereof, by a Limited Warranty
            Deed in the form of Exhibit III attached hereto (the "Deed").

     1.02   Property Title. On or before August 31, 1997, the BRI Partnership
            shall obtain a Commitment For Title Insurance for an ALTA Form B
            Owner's Title Insurance Policy (the "Commitment") from Lawyers Title
            Insurance Corporation (the "Title Insurer") and copies of all
            instruments and plans mentioned therein as exceptions to good and
            marketable fee simple title, as well as copies of any instruments
            referred to in such instruments which affect the Property (all of
            such items are hereinafter collectively referred to as the "Title
            Policy"). The BRI Partnership shall provide a copy of the Commitment
            to the Transferor Corporation promptly after its receipt thereof.
            The Commitment shall insure fee simple title to the Property in the
            sole name of the BRI Partnership and shall be in the amount of the
            Consideration Amount (as defined in Section 2.01(a) hereof). The
            Commitment shall provide for a title insurance policy which shall
            contain coverage against all mechanics' liens, shall have full
            survey coverage, shall have deleted therefrom all "printed standard
            exceptions", shall have a 3.1 zoning endorsement, a comprehensive
            endorsement and such other endorsements as are reasonably required
            by the BRI Partnership (provided, that the cost of any such other
            endorsements shall be paid by the BRI Partnership) and are available
            under the law of the state in which the Property is located.

     Should such Commitment contain any title exceptions which are not
acceptable to the BRI Partnership, in its sole discretion, the BRI Partnership
may notify the Transferor Corporation on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Corporation of any unacceptable exceptions as described above, the
exceptions set forth in Schedule B of the Commitment, except as otherwise herein
provided, shall be deemed accepted by the BRI Partnership and included as the
"Permitted Exceptions". If any exceptions are unacceptable to the BRI
Partnership and the BRI Partnership timely notifies the Transferor Corporation
in writing of such fact as above provided, the Transferor Corporation shall have
thirty (30) days from the date the Transferor Corporation receives notice of
such unacceptable exceptions, at the option of the Transferor 


                                      -3-


Corporation, to remove or cure such exceptions, provided further, the Transferor
Agent may, but shall not be required to, make any monetary expenditures in
connection with the removal or cure of such exceptions. All mortgages and deeds
of trust, mechanics liens, tax liens, attachments and all other monetary liens
against the Property (other than liens for real estate taxes and current water
and sewer charges for fiscal 1997 which taxes and current water and sewer
charges will be adjusted as provided in Section 12 hereof) (collectively the
"Monetary Liens") shall automatically be deemed to be unacceptable exceptions to
title and shall be paid and removed by the Transferor Corporation at Closing.
The Transferor Corporation shall be deemed to have refused to cure any
unacceptable exceptions unless the Transferor Corporation, within ten (10) days
after receipt of notice from the BRI Partnership, shall notify the BRI
Partnership in writing that the Transferor Corporation will attempt to cure such
unacceptable exceptions. If the Transferor Corporation fails or refuses to cure
said unacceptable exceptions within the time period above provided, on or before
the earlier to occur of (A) ten (10) days after the Transferor Corporation
notifies the BRI Partnership that it refuses to cure such unacceptable
exceptions, and (B) Closing Date, the BRI Partnership may, in accordance with
the provisions of Section 13 hereof, (i) terminate this Agreement by giving
written notice to the Transferor Corporation or (ii) waive such exceptions and
accept title subject thereto, in which event there shall be a reduction in the
Consideration Amount (as defined in Section 2.01(a)) in an amount necessary to
enable the BRI Partnership to remove all Monetary Liens.

     1.03   Survey. On or before August 31, 1997, the BRI Partnership, at the
            BRI Partnership's sole cost, shall obtain an as-built survey (the
            "Survey") of the Land and the Improvements by a registered land
            surveyor (the "Surveyor") acceptable to the BRI Partnership, which
            Survey shall include (i) all existing buildings, improvements,
            fences, encumbrances, encroachments, conflicts, party walls,
            protrusions (including the location of all highways, streets, roads,
            alleys and rights-of-way upon, under, across, abutting or adjacent
            to the Land, or affecting the Land or the Improvements), and any
            visible evidence of all water, sewer, gas, telephone and electric
            lines, (ii) the exact area of the Land to the nearest hundredth of
            an acre, (iii) all buildings set back and other restriction lines,
            (iv) property corners and boundary lines of the Property (including
            the courses and distances of each of said boundary lines), (v) the
            relation of the point of beginning of the description of the Land to
            the monument from which it is fixed, (vi) recorded or otherwise
            known easements (stating the recording book and page references in
            the case of any such recorded easements), (vii) a metes and bounds
            written description of the Land, and (viii) a notation of any
            discrepancies between the Survey and the recorded legal description.
            The BRI Partnership shall provide a copy of the Survey to the
            Transferor Corporation promptly after its receipt



                                      -4-


            thereof.

     Should such Survey contain any encumbrances, encroachments or other survey
defects (collectively "survey matters") which are not included within the
Permitted Exceptions and are not acceptable to the BRI Partnership in its sole
discretion, the BRI Partnership may notify the Transferor Corporation on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Corporation of the unacceptable
survey matters as described above, the Survey shall be deemed accepted by the
BRI Partnership and the survey matters shown on the Survey shall be included
within the "Permitted Exceptions." If any survey matters are unacceptable to the
BRI Partnership and the BRI Partnership timely notifies the Transferor
Corporation in writing of such fact as above provided, the Transferor
Corporation shall have thirty (30) days from the date the Transferor Corporation
receives notice of such unacceptable survey matters, at the option of the
Transferor Corporation, to cure such unacceptable survey matters. The Transferor
Corporation shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Corporation, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Corporation will attempt to cure such unacceptable survey
matters. If the Transferor Corporation fails or refuses to cure said
unacceptable survey matters within the time period provided, on or before the
earlier to occur of (A) ten (10) days after the Transferor Corporation notifies
the BRI Partnership that it refuses to cure such unacceptable survey matters,
and (B) Closing Date, the BRI Partnership may, in accordance with the provisions
of Section 13 hereof, (i) terminate this Agreement by giving written notice to
the Transferor Corporation or (ii) waive such survey matters and accept title
subject thereto, in which event there shall be no reduction in the Consideration
Amount.

     1.04   Due Diligence Inspection; Waiver; AS-IS Condition.

     (a) The BRI Partnership acknowledges that prior to the execution of this
Agreement, the BRI Partnership has been afforded the opportunity to inspect the
physical condition, financial condition and market condition of the Property
and, except as set forth herein with respect to the Environmental Inspection (as
defined in Section 1.04(b)), the BRI Partnership hereby waives any right to
terminate this Agreement based upon any matter which was the subject to said
inspections.

     (b) Notwithstanding the provisions of Section 1.04(a), subject to the
rights of the tenants under the Leases, the BRI Partnership and their authorized
agents and representatives may, from time to time up to and including October 1,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Corporation, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property


                                      -5-


with Environmental Laws (as defined in Section 5.21) and in connection therewith
to conduct such tests and observations and compile such information as the BRI
Partnership, in its sole discretion may deem appropriate (the "Environmental
Inspection"). The BRI Partnership shall provide a copy of any third party
environmental reports obtained by the BRI Partnership, without representation or
warranty, and subject to the limitations on use set forth therein, to the
Transferor Corporation promptly after its receipt thereof. No such inspection,
however, shall constitute a waiver or relinquishment on the part of the BRI
Partnership of its right to rely upon the covenants, representations, warranties
or agreements made by the Transferor Corporation in this Agreement. Should the
BRI Partnership decide, in its sole judgment, during the Due Diligence Period
that based upon the results of the Environmental Inspection, it no longer
desires to proceed with the transactions contemplated hereby, the BRI
Partnership shall have the right to terminate this Agreement by giving written
notice of its election to do so to the Transferor Corporation on or before the
last day of the Due Diligence Period, and upon the giving of such notice this
Agreement shall be of no further force or effect. If the BRI Partnership shall
fail to exercise such termination right within the Due Diligence Period, the BRI
Partnership shall be conclusively deemed to have waived any right it may have
had to terminate this Agreement pursuant to this Section 1.04(b). The BRI
Partnership shall pay when due all fees and expenses incurred in the performance
of the Environmental Inspection.

     (c) From and after the date of this Agreement, the Transferor Corporation
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Corporation's books, financial records, Service
Contracts, Leases and tenant files pertaining to the operation of the Property
prior to the Closing. The BRI Partnership's agents and representatives shall be
permitted access to such records and files during regular business hours. To the
extent that any of the Transferor Corporation's financial records relating to
the Property have been audited, the Transferor Corporation agrees to deliver any
reports relating to such audits to the BRI Partnership. The Transferor
Corporation shall provide the BRI Partnership with such information as the
Transferor Corporation may have with respect to actual expenditures made for all
repairs, maintenance, operation and upkeep of the Property, including, without
limitation, to the extent in the possession of the Transferor Corporation, all
taxes and utility payments made within three (3) years prior to the Closing and
dates of construction, installation and major repairs to the Property. All
information obtained by the BRI Partnership or its agents and representatives
pursuant to this Section 1.04(c) shall be treated as confidential, shall not be
disclosed to others until and unless the Closing occurs, and if such information
is in written form, such information shall be returned to the Transferor
Corporation if the Closing does not occur.


                                      -6-


     (d) The BRI Partnership shall indemnify the Transferor Corporation against
and from all damage to the Property and/or claims of tenants or other third
parties resulting from any entry on the Property by the BRI Partnership or any
agent, contractor, consultant or other representative of the BRI Partnership, or
any tests or other activities conducted in or on the Property by them, or any of
them, together with all expenses incurred by the Transferor Corporation by
reason thereof including, without limitation, reasonable attorneys' fees and
disbursements; provided, however, that nothing contained herein is intended to
obligate the BRI Partnership to indemnify, pay or otherwise reimburse the
Transferor Corporation for any costs of remediation or clean-up, fines,
penalties, assessments or similar charges for any condition existing at the
Property solely by reason of the fact that the BRI Partnership or its agents,
contractors, consultants or other representatives discover the existence of such
condition during the course of conducting tests or other activities on the
Property. The provisions of this Section 1.04(d) shall survive the Closing or
any termination of this Agreement; provided, however, that no claim by the
Transferor Corporation under this Section 1.04(d) for damage to the Property
shall be made if (i) the Closing occurs or (ii) more than 90 days after the
termination of this Agreement if the Closing does not occur, except for damage
claims made by tenants as to which the time for asserting any such claim shall
be not later than 180 days after the termination of this Agreement. If the
Closing occurs, the BRI Partnership shall not have any claim against the
Transferor Corporation by reason of any damage to the Property of the nature
specified above or by reason of any claim against which the BRI Partnership is
indemnifying the Transferor Corporation hereunder.

     1.05   Tax Treatment. The parties intend that the contribution of the
            Property by the Transferor Corporation to the BRI Partnership in
            accordance with Section 1.01 of this Agreement be treated for
            federal (and applicable state) income tax purposes as a tax-free
            contribution to capital pursuant to Section 721 of the Internal
            Revenue Code of 1986, as amended (the "Code") (and any analogous
            state income tax provisions). The BRI Partnership and the Transferor
            Corporation agree to report such transaction for federal and
            applicable state income tax purposes consistently with the intent
            set forth in this Section 1.05.

                                      -7-

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Corporation and the BRI Partnership agree that, subject
to the prorations and adjustments as provided in this Agreement, the
consideration (the "Consideration") for the contribution of the Property by the
Transferor Corporation to the BRI Partnership pursuant to this Agreement shall
be $1,250,311, which shall consist of BRI Partnership Units, to be issued by the
BRI Partnership to the Transferor Corporation as of the Closing, equal in value
(as such value is determined at the time and in the manner provided hereinbelow)
to the excess of (X) $1,250,311, subject to the prorations and adjustments as
provided in this Agreement, (the "Consideration Amount") minus (Y) the amount
required to pay the Loan in full.

     At the Closing, the BRI Partnership shall pay in full the outstanding
principal balance of the Note dated April 15, 1993, in the original principal
amount of $1,000,000 (the "Note") evidencing the loan (the "Loan") made to the
Transferor Corporation by Crestar Bank (successor to Loyola Federal Savings
Bank) ("Lender") and secured by the Loan Documents.

     At Closing, the Transferor Corporation will receive BRI Partnership Units
which will be entitled to distributions from the date of issuance (the "BRI
Partnership Units").

     At the Closing, the Transferor Agent shall deliver an investor
questionnaire in the form attached hereto as Exhibit 5 (the "BRI Questionnaire")
for the Transferor Corporation. In the event that the Transferor Corporation
would be entitled to a fractional BRI Partnership Unit, the number of BRI
Partnership Units shall be rounded up or down, as the case may be, to the
nearest whole BRI Partnership Unit. At Closing, the BRI Partnership shall
deliver to the Transferor Agent the BRI Partnership Confirmation evidencing the
issuance of the BRI Partnership Units to the Transferor Corporation. In
addition, if pursuant to Section 12, the BRI Partnership owes any amounts to the
Transferor Corporation as a result of prorations and apportionments (the "BRI
Additional Payment"), at Closing, the BRI Partnership shall pay the BRI
Additional Payment to the Transferor Agent in accordance with the election made
by the Transferor Corporation pursuant to Section 12.04. The Transferor Agent
shall be liable to distribute the BRI Partnership Units and if applicable, the
BRI Additional Payment to Transferor Corporation.


                                      -8-


     The parties agree that, for purposes of this Agreement, the value of each
BRI Partnership Unit (the "BRI Unit Value") shall be the average of the closing
price per share, rounded to the nearest one-thousandth, of one share of common
stock of BRI as such price is published by The Wall Street Journal for the
period from, and including, August 1, 1997 through and including, the date of
pricing of the Public Offering contemplated under Section 17.04 hereof, provided
that in any event the BRI Unit Value shall be not less than $10.50 per share
(the "Fixed Floor") and not greater than $11.75 per share (the "Fixed Ceiling").
The foregoing calculation of BRI Unit Value (including the Fixed Floor and Fixed
Ceiling) will be adjusted as appropriate and customary upon the occurrence of
any of the following events to reflect a stock split, dividend (outside of the
ordinary course), recapitalization or other similar event outside of the
ordinary course.

     (b) As used in this Agreement, a "BRI Partnership Unit" shall mean a unit
of limited partnership interest in the BRI Partnership as specified in the BRI
Partnership Agreement. At the time that the Transferor Corporation elects to
convert BRI Partnership Units to shares as provided in the BRI Partnership
Agreement, the holder of each BRI Partnership Unit shall have the right to have
the BRI Partnership Unit either (i) exchanged for one share of common stock of
BRI pursuant to the transfer provisions of the BRI Partnership Agreement, or
(ii) redeemed for cash at the option of BRI on such terms and conditions as are
specified in the BRI Partnership Agreement. The Transferor Corporation shall
have such additional rights with respect to its BRI Partnership Units as are
contained in the Registration Rights Agreement, the form of which is attached
hereto as Exhibit 4; at Closing, the Transferor Corporation and BRI Apartments
shall execute and deliver an Amendment to the BRI Partnership, in the form and
substance of Exhibit 3 attached hereto (the "BRI Partnership Amendment") and the
BRI Partnership shall deliver to the Transferor Corporation a certified copy of
the Registration Rights Agreement.

     (c) The Transferor Corporation acknowledges and agrees that after the
execution hereof, the price of the common stock of BRI may increase or decrease
in value as the result of market fluctuations prior to the Public Offering, and
that any such fluctuations will have an impact on the value of the BRI
Partnership Units. Notwithstanding these fluctuations, once the value and number
of BRI Partnership Units have been established as provided in Section 2.01(a),
the BRI Partnership will not be required to increase or permitted to decrease
the number of BRI Partnership Units to be issued to the Transferor Corporation
in the event of a decrease or increase in the market value of the common stock
of BRI subsequent to the closing of the Public Offering and the fixing of the
Offering Price.

     2.02   Payment of Monies. Any other monies payable under this Agreement,
            unless otherwise specified in this Agreement, shall be paid by wire


                                      -9-


            transfer.

     2.03   Retention of Escrow. At the Closing, the Transferor Corporation
            shall retain the escrow deposits set forth on Schedule C attached
            hereto.


                                    SECTION 3

                                     CLOSING

     3.01   Closing. Except as otherwise provided in this Agreement, the
            delivery of all documents necessary for the closing of the
            transactions contemplated by this Agreement (the "Closing") shall
            take place in the offices of Hale and Dorr LLP, 60 State Street,
            Boston, Massachusetts 02109, or such other place as the Transferor
            Corporation and the BRI Partnership shall mutually agree, at 10:00
            A.M. local time on a date mutually agreed to in writing by the
            parties but in any event not later than October 31, 1997 the
            ("Closing Date"). The "Time of Closing" shall be at such time as all
            recordable instruments necessary for the closing of the transactions
            contemplated by this Agreement shall be placed in escrow with the
            Title Insurer, who will thereupon issue the Title Policy referred to
            in the Commitment in reliance on the execution by the Transferor
            Agent pursuant to a Power of Attorney for the Transferor Corporation
            granted under Section 19.04 of a so-called Gap Indemnity in the form
            of Exhibit VI with respect to the gap in time period between policy
            issuance and recording, all as provided in a letter of instruction
            executed by counsel for the BRI Partnership and counsel for the
            Transferor Corporation. It is agreed that time is of the essence of
            this Agreement.


                                    SECTION 4

                       TRANSFEROR'S PRE-CLOSING DELIVERIES

            Adverse Effect. Neither the execution, delivery and performance of
            this Agreement by the Transferor Corporation, nor the contribution
            of the Property by the Transferor Corporation hereunder, will result
            in any Material Adverse Effect or be in conflict with or constitute
            a default under the Transferor Corporation's articles of
            incorporation or bylaws or result in the creation of any mortgage,
            pledge, lien, encumbrance or charge upon any of the properties or

            Exceptions.

            Corporation's knowledge, any threat thereof, against the Transferor
            Corporation or the Property or any part thereof which questions the
            validity of this Agreement or the right of the Transferor
            Corporation to enter into it, or which might result in or have,
            either individually or in the aggregate, a material adverse effect
            on (i) the business of the Transferor Corporation as such is
            presently contemplated; or (ii) the Property. During the period

            Property is an independent unit which does not now rely on any
            facilities (other than facilities covered by Permitted Exceptions or
            facilities of municipalities or public or private utility and water
            companies) located on any property not included in the Property to
            fulfill any municipal or governmental requirement or for the
            furnishing to the Property of any essential building systems or
            utilities. Except as set forth on Schedule 5.28, no property not
            included in the Property relies for its operation, maintenance or
            legal compliance on any facilities located on the Property.

     5.29   Legal Access. There is direct legal access from a public way to the
            Property. To the best knowledge of the Transferor Corporation, all
            necessary curb cuts, access permits and other governmental approvals
            required to provide such access have been issued and are in full
            force and effect.

     5.30   Public Improvements. To the best knowledge of the Transferor
            Corporation, there are no written or proposed plans to widen,
            modify, or realign any street or highway or any existing or proposed
            eminent domain proceedings which would affect the Property in any
            way whatsoever. To the best knowledge of the Transferor Corporation,
            there are no presently planned public improvements which would
            result in the creation of a special improvement or similar lien upon
            the Property.

     5.35   Investment Representations and Warranties. The Transferor
            Corporation represents, warrants, acknowledges and agrees as
            follows:


                                      -19-


     (a) The Transferor Corporation is acquiring the BRI Partnership Units for
investment only to be received by it for its own account and not with any view
to the sale or distribution of the same or any part thereof in violation of the
Securities Act of 1933, as amended (the "Act") and it will not sell or otherwise
dispose of such BRI Partnership Units except in compliance with the registration
requirements or exemption provisions of any applicable securities laws and in
accordance with the terms of the BRI Partnership Agreement and the Registration
Rights Agreement.

     (b) The Transferor Corporation understands that the BRI Partnership Units
to be issued to it will not be registered under the Act, or the securities laws
of any state ("Blue Sky Laws") by reason of a specific exemption or exemptions
from registration under the Act and applicable Blue Sky Laws and that BRI's and
the BRI Partnership's reliance on such exemptions is predicated in part on the
accuracy and completeness of the representations and warranties of the
Transferor Corporation.

     (c) The Transferor Corporation acknowledges and agrees that, for the
reasons set forth in Sections 5.35(a) and (b) above, the BRI Partnership Units
(or shares of common stock issued upon exchange of the BRI Partnership Units)
may not be offered, sold, transferred, pledged, or otherwise disposed of by the
Transferor Corporation except (i) pursuant to an effective registration
statement under the Act and any applicable Blue Sky Laws, (ii) pursuant to a
no-action letter issued by the Securities and Exchange Commission to the effect
that a proposed transfer of the BRI Partnership Units (or shares of common stock
issued upon exchange of the BRI Partnership Units) may be made without
registration under the Act, together with either registration or an exemption
under applicable Blue Sky Laws, or (iii) upon the BRI Partnership or BRI, as the
case may be, receiving an opinion of counsel knowledgeable in securities law
matters (and which opinion and counsel shall be reasonably acceptable to both
the BRI Partnership and BRI) to the effect that the proposed transfer is exempt
from the registration requirements of the Act and any applicable Blue Sky Laws,
and that, accordingly, the Transferor Corporation must bear the economic risk of
an investment in the BRI Partnership Units (and the shares of common stock
issued upon exchange of the BRI Partnership Units) for an indefinite period of
time. The Transferor Corporation acknowledges, represents and agrees that (i)
its economic circumstances are that it is able to bear all risks of the
investment in the BRI Partnership and BRI for an indefinite period of time,
including the risk of a complete loss of its investment in the BRI Partnership
Units (or shares of common stock issued upon exchange of the BRI Partnership
Units), (ii) it has knowledge and experience in financial and business matters
sufficient to evaluate the risks of investment in the BRI Partnership Units and
BRI, and (iii) it has consulted with its own separate counsel and tax advisor,
to the extent deemed necessary by it, as to all legal and taxation matters
covered by this Agreement and has not relied upon the BRI Partnership or the
Transferor Agent, its 


                                      -20-


affiliates or its other legal counsel and advisors for any explanation of the
application of the various United States or state securities laws or tax laws
with regard to its acquisition of the BRI Partnership Units. The Transferor
Corporation further acknowledges and represents that it has made its own
independent investigation of the BRI Partnership and the business conducted or
proposed to be conducted by the BRI Partnership.

     (d) The Transferor Corporation is an "accredited investor" within the
meaning of Rule 501(a) promulgated under the Act.

     (e) The Transferor Corporation understands that an investment in the BRI
Partnership and BRI involves substantial risks. The Transferor Corporation
acknowledges that it has (i) been given full and complete access to the BRI
Partnership and its management in connection with this Agreement and the
transactions contemplated hereby, (ii) received and read the BRI Partnership
Agreement, as amended to date, and has had the opportunity to review all
documents and information relevant to its decision to enter into this Agreement
and to invest in the BRI Partnership and BRI, including, without limitation, the
Private Placement Memorandum of BRI, dated as of August 25, 1997 (the "PPM") and
(iii) had the opportunity to ask questions of the BRI Partnership and BRI and
its management concerning its investment in the BRI Partnership and the
transactions contemplated hereby, which questions were answered to its
satisfaction.

     (f) The Transferor Corporation acknowledges and agrees that:

          (i) the BRI Partnership Units to be acquired by it hereunder will not
     be registered under the Act in reliance upon the exemption afforded by
     Section 4(2) thereof for transactions by an issuer not involving any public
     offering, and will not be registered or qualified under any other
     applicable securities laws;

          (ii) any shares of common stock issued upon exchange of the BRI
     Partnership Units, unless registered under the Act pursuant to an effective
     Registration Statement, will bear a legend substantially to the effect of
     the following:

               "The securities represented by this certificate have not been
               registered under the Securities Act of 1933, as amended (the
               "Act"), or the securities laws of any state. The securities may
               not be offered, sold, transferred, pledged or otherwise disposed
               of without an effective registration statement under the Act and
               under any applicable state securities laws, 


                                      -21-


               receipt of a no-action letter issued by the Securities and
               Exchange Commission (together with either registration or an,
               exemption under applicable state securities laws) or an opinion
               of counsel (which opinion and which counsel shall be acceptable
               to Berkshire Realty Company, Inc.) that the proposed transaction
               will be exempt from registration under the Act and its applicable
               state securities laws"; and

          (iii) unless such shares have been registered under the Act as
     aforesaid, BRI reserves the right to place a stop order against the
     transfer of the BRI Partnership Units, (and any shares of common stock
     issued upon exchange of the BRI Partnership Units) and to refuse to effect
     any transfers thereof, in the absence of satisfying the conditions
     contained in the foregoing legend.

     (g) The address set forth in the first paragraph of this Agreement is the
address of the Transferor Corporation's principal place of business, and the
Transferor Corporation has no present intention of becoming a resident of any
country, state or jurisdiction other than the country and state in which such
principal residence or principal place of business is situated.

     (h) The provisions of this Section 5.35 shall survive the Closing
indefinitely.

     5.36   Receipt of Documents. The Transferor Corporation has received all
            Exhibits and Schedules described herein as attached hereto.

     6.02   Partnership Authority. (i) The BRI Partnership is a limited
            partnership duly organized and validly existing and in good standing

            and covenants contained in this Agreement and contemplated hereby
            and any other documents and instruments relating hereto or thereto;
            (iii) this Agreement and the documents to be executed and delivered
            by the BRI Partnership at Closing, upon execution and delivery will
            have been duly and validly authorized and executed by the BRI
            Partnership and will constitute the valid and binding obligations of
            the BRI Partnership, enforceable in accordance with their respective
            terms, subject only to applicable bankruptcy, insolvency,
            reorganization, moratorium and other laws for the relief of debtors
            theretofore or hereafter enacted to the extent that the same may be
            constitutionally applied; and (iv) assuming compliance with the
            terms of this Agreement and the BRI Partnership Agreement by the
            parties hereto and thereto other than the BRI Partnership, the
            execution and delivery by the BRI Partnership of the BRI Partnership
            Units, this Agreement and all other documents and instruments
            contemplated hereby and the performance by the BRI Partnership of
            its obligations hereunder and thereunder do not and will not
            constitute a default under, or conflict with or violate, any
            provision of the BRI Partnership Agreement or any other material
            agreement to which the BRI Partnership is a party or by which the
            BRI Partnership is bound.

            of the BRI Partnership included or incorporated by reference in the
            SEC Filings and the PPM have been prepared in accordance with
            generally accepted accounting principles applied on a consistent
            basis during the periods involved (except as may be indicated in the
            notes thereto) and fairly present in all material respects the


                                      -23-


            consolidated assets, liabilities and financial position of the
            general partner of the BRI Partnership as of the dates thereof and
            the consolidated results of its operations and changes in cash flow
            for the periods then ended (subject, in the case of any unaudited
            interim financial statements, to normal year end adjustments).

     6.04   Governmental Consent, etc. Except as disclosed in the PPM, no

            or filing with, any governmental agency, commission, board or public
            authority is required on the part of the BRI Partnership in
            connection with the valid execution and delivery of this Agreement
            by the BRI Partnership and the performance of the BRI Partnership's

            only agreement among the partners relating to the organization,
            operation, or management of the BRI Partnership, (ii) is in full
            force and effect and (iii) has not been amended or modified. A true,
            correct and complete copy of the BRI Partnership Agreement is
            attached hereto as Exhibit 1. Except as contemplated hereby or set
            forth in the SEC Filings, the BRI Partnership has no commitment to
            issue any right to purchase or acquire or to issue or distribute to
            any of the owners of partnership interests in the BRI Partnership
            (the "BRI Partners"), any evidences of indebtedness or assets and
            the BRI Partnership has no obligation, contingent or otherwise, to
            purchase, redeem or otherwise acquire any interest in the BRI
            Partnership or to make any distribution in respect thereof. Upon the
            Closing, good, valid and marketable title to the BRI Partnership
            Units shall be vested in the Transferor Corporation free and clear
            of any lien, claim, charge, pledge encumbrance, limitation,
            agreement or instrument whatsoever.

     6.06   Tax Matters.

     (a) All federal, state, local and foreign tax returns and information
statements required to be filed by or on behalf of the BRI Partnership or for
which the BRI Partnership may have any liability have been accurately prepared
in all material respects and duly and timely filed (or requests for extensions
have been timely field, granted and have not expired). As of the date hereof,
there is no audit examination, deficiency or refund litigation or matter in
controversy with respect to any taxes that might result in a determination
materially adverse to the BRI Partnership. All taxes due with respect to
completed and settled examinations or concluded litigation have been paid.

     (b) The BRI Partnership has not executed an extension or waiver that is


                                      -24-


currently in effect of any statute of limitations on the assessment or
collection of any tax.

     (c) The BRI Partnership does not know of (A) any audit or investigation of
the BRI Partnership with respect to any liability for taxes relating to the BRI
Partnership for which any BRI Partner may be liable, or (B) any threatened
claims or assessments for taxes against or relating to the BRI Partnership.

     6.07   Bankruptcy. No attachments, execution proceedings, assignments for
            the benefit of creditors, insolvency, bankruptcy, reorganization or
            other similar proceedings are pending or, to the BRI Partnership's
            knowledge, threatened against the BRI Partnership, nor are any of
            such proceedings anticipated or contemplated by the BRI Partnership.

     6.08   Private Placement Memorandum. The PPM, as of the date thereof and as
            of the dates of any amendment thereof, did not contain an untrue
            statement of material fact or omit to state a material fact required
            to be stated therein or necessary in order to make the statements
            therein, in light of the circumstances under which they were made,
            not misleading.

     6.09   REIT Status. Commencing with BRI's taxable year ending December 31,
            1991, BRI has been organized in conformity with the requirements for
            qualification as a "real estate investment trust" and its method of
            operation has enabled and to BRI's knowledge should enable it to
            meet the requirements for qualification and taxation as a "real
            estate investment trust" under the Internal Code of 1986, as
            amended.

     6.10   Issuance of Units. The BRI Partnership Agreement provides, or prior
            to Closing will provide, for the issuance of the BRI Partnership
            Units. The BRI Partnership Units to be issued in connection with the
            transactions herein contemplated have been, or prior to their
            issuance will have been, duly authorized for issuance by the BRI
            Partnership to the Transferor Corporation, and on the date of their
            issuance pursuant to the terms and conditions hereof will be validly
            issued, fully paid and non-assessable, free and clear of any liens,
            pledges and encumbrances of any kind whatsoever. Any and all shares
            of common stock of BRI exchangeable for BRI Partnership Units issued
            in connection with the transactions herein contemplated will be duly
            authorized, validly issued, fully paid and non-



                                      -25-


            assessable, free and clear of any liens, pledges and encumbrances of
            any kind whatsoever. All issued and outstanding shares of common 
            stock of BRI were issued in compliance with or in transactions 
            exempt from the registration provisions of applicable federal and 
            state securities laws.

     6.11   Receipt of Documents. The BRI Partnership acknowledges that it has
            received all of the documents described herein as delivered thereto
            (unless it has notified the Transferor Corporation otherwise in
            writing) and represents that there are no other documents known to
            the BRI Partnership which are required to be delivered hereunder
            which have not been so delivered.

     6.12   Litigation, etc. Except as described in the SEC Filings there is no
            material action, suit or, to the BRI Partnership's knowledge,
            proceeding or investigation pending or, to the BRI Partnership's
            knowledge, any threat thereof, against the BRI Partners, the BRI
            Partnership or its properties or any part thereof which questions
            the validity of this Agreement and the transactions contemplated
            hereby or the right of the BRI Partnership to enter into it, or
            which would likely have, either individually or in the aggregate, a
            material adverse effect on the business of the BRI Partnership as
            such is presently conducted.

     6.13   Title to Properties and Assets. The BRI Partnership or its
            subsidiaries or affiliates is the owner as described in the SEC
            Filings with good title to its properties as described in the SEC
            Filings, subject to such financings, easements, restrictions and
            other matters which do not have a material adverse effect on the
            operation of such properties in accordance with the BRI
            Partnership's past practices. Except as disclosed in the SEC
            Filings, the BRI Partnership does not own, or otherwise hold any
            interest in, any other material properties.

     6.14   Liabilities. Except as disclosed in the SEC Filings, the BRI
            Partnership has no material liabilities and the BRI Partnership has
            not, directly or indirectly, created, incurred, assumed or
            guaranteed or otherwise become directly or indirectly liable for the
            payment of any material amount of borrowed money.

     6.15   Environmental Compliance. Except as disclosed in the SEC Filings, no
            action has been commenced by any enforcement agency under any
            Environmental Laws which, if adversely determined, would have a
            material adverse effect on the BRI Partnership and BRI is not in
            material violation of any Environmental Laws to such an extent that
            it would have 


                                      -26-


            a material adverse effect on the BRI Partnership.

     6.16   Permits and Compliance with Laws. Except as disclosed in the SEC
            Filings, the BRI Partnership has not received written notice that
            (i) any material approvals, consents, permits, licenses or
            certificates of occupancy (whether governmental or otherwise)
            required for the current use and operation of any of its properties
            have not been granted, effected, renewed or performed and completed
            (as the case may be) or have been or are about to be revoked; (ii)
            any fees and charges therefor have not been fully paid; (iii) any of
            its properties, including the current use and occupancy thereof are
            in violation in any material respect of any laws or (iv) any
            governmental authority has a current plan that would adversely
            affect the continued use and operation of any of its properties as
            currently used and operated except, in the case of clauses (i),
            (ii), (iii) and (iv), as would not have a Material Adverse Effect.


                                    SECTION 7

                             INSURANCE AND CASUALTY

     7.01   Maintenance of Insurance. Until the Closing Date, the Transferor
            Corporation shall maintain its present insurance on the Property
            which insurance in respect of fire and casualty shall be covered by
            a standard All-Risk Policy in the amounts as currently insured. A
            certificate or certificates of such insurance shall be provided to
            the BRI Partnership upon written request by the BRI Partnership.
            Subject to the provisions of Section 7.02, the risk of loss in and
            to the Property shall remain vested in the Transferor Corporation
            until the Time of Closing.

     7.02   Casualty or Condemnation. If prior to the Time of Closing, the
            Improvements or any material portion thereof (having a replacement
            cost equal to or in excess of $100,000.00) are damaged or destroyed
            by fire or casualty, or if any material part of the Property is
            subject to any eminent domain notice or proceeding by any
            governmental entity (which shall mean for purposes of this Section
            7.02 a proceeding which affects any units, parking spaces or
            material amenities), then the BRI Partnership shall have the option,
            exercisable by written notice given to the Transferor Corporation at
            or prior to the Time of Closing, either to (a) terminate this
            Agreement, whereupon all obligations of all parties hereto shall
            cease, and this Agreement shall be void and without recourse to the
            parties hereto except for provisions which are expressly stated to
            survive such



                                      -27-


            termination; or (b) proceed with the contribution and transfer of
            the Property, and in such case, unless the Transferor Corporation

            exceeds $25,000.00, to remove such Violations of Law or comply with
            such notices by the Closing Date, the BRI Partnership shall have the
            option to (i) terminate this Agreement, whereupon all obligations of
            all parties hereto shall cease and this Agreement shall be void and
            without recourse to the parties hereto, except for provisions which
            are expressly stated to survive such termination, or (ii) proceed

            be a reduction in the Consideration Amount in an amount necessary to
            enable the BRI Partnership to remove such Violations of Law,
            provided such reduction shall not in any event exceed $25,000.00,
            and the obligations of the Transferor Corporation with respect to
            such violations shall cease.

            shall be not less than the amount of the market rent noted on the
            Rent Roll for the respective apartment; or (b) amend any Lease for
            an apartment unit with an existing tenant, or (c) renew or extend

            withheld or delayed, provided no consent shall be required with

the Transferor Corporation has any indemnification obligation to the BRI
Partnership, the Transferor Corporation may elect to satisfy such
indemnification obligation by directing the BRI Partnership to cancel such

Partnership Units are returned or cancelled) equal to the indemnification
obligation of the Transferor Corporation.

the Transferor Corporation for which the BRI Partnership is indemnified under
Section 10.05(a) above); provided that the BRI Partnership shall not be required
to indemnify the Transferor Corporation under Section 10.05(b)(i) for any
amounts in excess of 50% of the fair market value as of the date such

payable unless such claim has been agreed to by the parties or has been finally
determined by a final, non-appealable judicial decision.

     (d) The amount of the indemnifying party's liability under this Agreement
shall be determined taking into account any applicable insurance proceeds
actually received by, and other savings that actually reduce the impact of
losses upon, the indemnified party.

     (e) Neither the BRI Partnership nor the Transferor Corporation shall have
any liability for claims made under Section 10.05(a) or 10.05(b) unless and
until the aggregate amount of all losses incurred exceeds $50,000 (in which case
the indemnifying party shall be liable for the portion of losses exceeding
$50,000).

     (f) The indemnification provided in this Section 10 shall be the sole and
exclusive remedy after the Closing Date for damages available to the BRI
Partnership or the Transferor Corporation for a breach of any of the terms,
conditions, representations or warranties contained herein, and each party
acknowledges and agrees that other than the representations and warranties set
forth herein, no other representations and warranties are being made with
respect to the BRI Partnership, the Transferor Corporation or the Property.

     (g) Each of the Transferor Corporation and the BRI Partnership acknowledge
and agree that, unless otherwise agreed to in writing by all the parties, from
and after the Closing, each of the parties hereto will be deemed to have waived
any right to seek indemnification hereunder from the other party for any breach
or default of a representation, warranty or obligation hereunder by such other
party to the extent that the party seeking indemnification had actual knowledge
of such breach or default by such other party on or prior to Closing.

                                      -38-


Corporation pursuant to any other provisions of this Agreement or which the
Transferor Corporation may, either at or subsequent to the Closing, deem
reasonably necessary in order to consummate the transactions contemplated by
this Agreement or to better vest in the Transferor Corporation title to the BRI
Partnership Units. The provisions of this Section 11.01(h) shall survive the
Closing indefinitely.

     11.02  Partnership's Expenses. The BRI Partnership shall pay its own
            counsel fees, and one-half of all (i) Title Insurance and Survey
            costs, (ii) escrow and recording costs and (iii) UCC search costs.

     11.03  Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Corporation, in its
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Corporation has not dissolved, terminated or liquidated, the right to
receive the Property as a distribution in kind in satisfaction of the Transferor
Corporation's distribution rights under Section 8.2 of the BRI Partnership
Agreement. If the Property is contributed by the BRI Partnership to a Subsidiary
Entity (as defined in the BRI Partnership Agreement), the BRI Partnership shall
cause such Subsidiary Entity, to take such actions as may be necessary to
effectuate the foregoing right granted by the BRI Partnership to the Transferor
Corporation.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Corporation redeemed all
of the BRI Partnership Units received by the Transferor Corporation hereunder
for cash or for shares of BRI common stock or (II) seven (7) years from the
Closing Date, neither the BRI Partnership nor BRI shall allow the sale or
transfer of the Property, except for (i) transfers that are fully tax-free to
partnerships in which the BRI Partnership has an interest, (ii) exchanges that
are fully tax-free pursuant to Section 1031 of the Code and (iii) involuntary
transfers which shall include, without limitation, a foreclosure, a deed-in-lieu
of foreclosure, a condemnation or a liquidation of the BRI Partnership or BRI,
provided that in the event of a condemnation, the BRI Partnership shall use
reasonable efforts to reinvest the net condemnation proceeds in accordance with
Section 1033 of the Code and hold the same until the expiration of the No
Transfer Period.

     (c) Intentionally Deleted.

     (d) Section 704(c) Method. The BRI Partnership shall elect the "traditional
method" as described in Treasury Regulation Section 1.704-3(b) with respect to
the Property or any interest therein.

     (e) Allocation of Excess Nonrecourse Liabilities. For purposes of


                                      -39-


allocating the "excess nonrecourse liabilities" (within the meaning of Treasury
Regulations Section 1.752-3(a)(3)) of the BRI Partnership among the partners
(including the Transferor Partners), the BRI Partnership will allocate one half
of such excess nonrecourse liabilities among its partners based upon each
partner's relative number of BRI Partnership Units (taking into account
Restricted Distribution BRI Partnership Units) and the remainder of such excess
nonrecourse liabilities will be allocated among the partners based on each
partner's relative share of the BRI Partnership's Section 704(c) "minimum gain."
The foregoing method shall not be modified by the BRI Partnership until the
expiration of the No Transfer Period without the consent of the Transferor Agent
(which consent may only be granted if none of the Transferor Partners is
materially adversely affected unless the consent of such materially adversely
affected Transferor Partners is obtained), provided however that in the event of
a change in the Code, the Treasury Regulations, or published Internal Revenue
Service ("IRS") rulings, notices or other administrative guidance, or in any
private letter ruling issued to a taxpayer other than the BRI Partnership (any
such change, a "Change in Law") such that, in the reasonable opinion of tax
counsel to the BRI Partnership, based on such Change in Law, either (i) the
foregoing method is no longer legally permissible, (ii) or an alternative
method, not previously permitted, which results in more favorable tax
consequences to each of the limited partners, including the Transferor Partners,
of the BRI Partnership is currently permitted, the BRI Partnership, shall be
entitled, without the consent of the Transferor Agent, to adopt an alternative
method, provided further that, in the case of clause (i), the BRI Partnership
shall choose the alternative method that minimizes to the extent reasonably
possible, the adverse tax consequences to the Transferor Partners.

     (f) The provisions of this Section 11.03 shall survive the Closing
indefinitely.


                                   SECTION 12

                 APPORTIONMENTS AND ADJUSTMENTS TO CONSIDERATION

Apportionments. The following apportionments shall be made between the parties
on the Closing Date as of the close of the business day prior to the Closing
Date and the net amount of such prorations and apportionments shall be settled
in accordance with Section 12.04:

     (a) prepaid and collected rent;

     (b) real estate and personal property taxes, water charges, sewer rents and
vault charges, if any, on the basis of the fiscal period for which assessed,
except that 


                                      -40-


if there is a water meter on the Property, apportionment on the Closing Date
shall be based on the last available reading, subject to adjustment after the
Closing on a per diem basis, when the next reading is available;

     (c) intentionally deleted;

     (d) charges or prepayments under transferable Service Contracts; and

     (e) all other income and expenses relating to the Property, including
without limitation, income from cable television services as are customarily
adjusted in real estate transactions of this size and type in Baltimore,
Maryland.

     If as of the Closing Date, any items of income or expense attributable to
the Property are not known or available, the parties agree to equitably
apportion such items, so long as the same are identified within 90 days after
the Closing. If the Closing Date shall occur before the applicable real estate
or personal property tax rate is fixed, the apportionment of taxes on the
Closing Date shall be upon the basis of the tax rate for the preceding period
applied to the latest assessed valuation. Promptly after the new tax rate is
fixed, the apportionment of taxes shall be recomputed. Any discrepancy resulting
from such recomputation and any material errors or omissions in computing any
apportionments on the Closing Date shall be promptly corrected, which obligation
shall survive the Closing Date for a period of ninety (90) days after Closing.

     At least five (5) days prior to the Closing Date, the Transferor Agent and
the BRI Partnership shall prepare and exchange preliminary calculations of all
adjustments and prorations to be made pursuant to this Section 12. The
Transferor Agent and the BRI Partnership shall cooperate in the furnishing of
all information and documentation necessary to prepare such calculations.

     Subject to Section 12.04, all cash shall be used by the Transferor
Corporation to pay amounts payable by the Transferor Corporation and/or
distributed to the Transferor Corporation prior to Closing, and if any of such
cash applicable to pre-closing periods is not removed from the Transferor
Corporation prior to Closing, all such cash shall remain the property of the
Transferor Corporation.

     12.01  Application of Rent Payments. If any tenant is in arrears in the
            payment of rent on the Closing Date, the Transferor Corporation
            shall retain the right to receive such rent. The BRI Partnership
            shall act as agent for the Transferor Corporation in collecting such
            rent. Rents received from such tenant after the Closing shall be
            applied in the following order of priority: (a) first to the month
            in which the Closing occurred; (b) then to any month or months
            following the month in which the Closing occurred until all 



                                      -41-


            unpaid rents have been paid in full; and (c) then to the period 
            prior to the month in which the Closing occurred. After Closing, the
            BRI Partnership shall use reasonable efforts to collect delinquent
            rents attributable to the period prior to the month in which Closing
            occurred, provided such efforts shall not require the commencement
            of litigation against any such tenant. If rents or any portion
            thereof received by the Transferor Corporation or the BRI
            Partnership after the Closing are payable to the other party by
            reason of this allocation or otherwise, the appropriate sum shall be
            paid to the other party within thirty (30) days from the receipt
            thereof, which obligation shall survive the Closing.

     12.02  Security Deposits. The Transferor Corporation shall assign and
            deliver to the BRI Partnership all of the tenant security deposits,
            including interest accrued thereon at the rate of 4% as required by
            applicable state law or at such higher rate, if any, as required by
            the terms of the leases, for each tenant as shown on the Rent Roll
            and the BRI Partnership, or its designee, shall assume all liability
            with respect to the tenant security deposits under applicable state
            law and/or the terms of the Leases.

     12.03  Election of Form of Payment. If as a result of the prorations and
            apportionments set forth in Section 12.01, the Transferor
            Corporation owe an amount to the BRI Partnership, the Transferor
            Corporation shall have the right to elect to adjust for such amounts
            owing by the Transferor Corporation to the BRI Partnership in the
            form of BRI Partnership Units rather than cash. In addition, if as a
            result of the prorations and apportionments set forth in Section
            12.01, the BRI Partnership owes an amount to the Transferor
            Corporation, such amount shall be paid in the form of BRI
            Partnership Units rather than cash. The Transferor Agent shall have
            the right to elect to adjust for amounts owing to the Transferor
            Corporation or the BRI Partnership, as the case may be, in the form
            of cash and/or BRI Partnership Units. The Transferor Agent shall
            notify the BRI Partnership at least seven (7) business days prior to
            the Closing Date of the manner in which the Transferor Corporation
            shall have elected to settle adjustments under Section 12.


                                   SECTION 13

                               FAILURE TO PERFORM

     13.01  Defective Title or Condition. If the Transferor Corporation is
            unable to give title or to contribute and transfer the Property, or
            to satisfy all of the 



                                      -42-


            terms and conditions precedent to closing as set forth in this 
            Agreement, all as herein stipulated, or if on the scheduled closing
            the Property does not conform with the provisions hereof, the BRI
            Partnership may elect by written notice given to the Transferor
            Agent on or before the Closing Date either (a) to take title as
            provided in Section 13.02, or (b) to terminate this Agreement as
            provided in Section 13.03.

     13.02  BRI Partnership Election. The BRI Partnership shall have the right
            to elect, in its sole discretion, on the Closing Date, to accept
            such title as the Transferor Corporation can deliver to the Property
            in its then condition and to deliver in exchange therefor the
            Consideration subject to reduction of the Consideration Amount by
            the amounts required to remove all Monetary Liens.

     13.03  Transferor Corporation's Default. If on the Closing Date, the
            Transferor Corporation has failed to perform all of the material
            obligations of the Transferor Corporation under this Agreement, the
            Transferor Corporation shall be in default under this Agreement and
            the BRI Partnership shall be entitled to terminate this Agreement by
            written notice given to the Transferor Agent within seven (7) days
            after the Closing Date and thereafter this Agreement shall be void
            and without recourse to any party hereunder except for provisions
            which are expressly stated to survive termination of this Agreement.
            In addition to the foregoing, if the BRI Partnership desires to
            accept the contribution and transfer of the Property in accordance
            with the terms of this Agreement and the Transferor Corporation
            willfully refuses to perform the Transferor Corporation's
            obligations hereunder, the BRI Partnership, at its option, shall
            have the right to compel specific performance by the Transferor
            Corporation hereunder, in which event the BRI Partnership shall have
            the right to recover from the Transferor Corporation the amount of
            all reasonable legal fees, court costs and other litigation expenses
            incurred by the BRI Partnership in connection with the exercise of
            its right of specific performance. The remedies provided in this
            Section 13.03 shall be the sole and exclusive remedies at law or in
            equity of the BRI Partnership in the event of a default by the
            Transferor Corporation in lieu of all other rights and remedies
            which the BRI Partnership may have against the Transferor
            Corporation at law or in equity.

     13.04  BRI Partnership's Default. If on the Closing Date, the BRI
            Partnership has failed to perform all of the material obligations of
            the BRI Partnership under this Agreement, the BRI Partnership shall
            be in default under this Agreement and the Transferor Agent shall be
            entitled to terminate this 



                                      -43-


            Agreement by written notice given to the BRI Partnership within 
            seven (7) days after the Closing Date and thereafter this Agreement
            shall be void and without recourse to any party hereunder except for
            provisions which are expressly stated to survive termination of this
            Agreement. In addition to the foregoing, if the Transferor
            Corporation desires to accept the transfer of the BRI Partnership
            Units in accordance with the terms of this Agreement and the BRI
            Partnership willfully refuses to perform the BRI Partnership's
            obligations hereunder, the Transferor Corporation, at its option,
            shall have the right to compel specific performance by the BRI
            Partnership hereunder, in which event the Transferor Corporation
            shall have the right to recover from the BRI Partnership the amount
            of all reasonable legal fees, court costs and other litigation
            expenses incurred by the Transferor Corporation in connection with
            the exercise of its right of specific performance. The remedies
            provided in this Section 13.04 shall be the sole and exclusive
            remedies at law or in equity of the Transferor Corporation in the
            event of a default by the BRI Partnership in lieu of all other
            rights and remedies which the Transferor Corporation may have
            against the BRI Partnership at law or in equity.


                                   SECTION 14

                          BROKERAGE AND LOAN PREPAYMENT

     14.01  Brokerage Fees. The Transferor Corporation and the BRI Partnership
            mutually represent and warrant that neither of them has retained a
            broker, finder or similar agent who might have a claim or right to
            claim a commission or fee in connection with this transaction. The
            Transferor Corporation understands that American Property
            Consultants ("APC") had entered into a fee arrangement with Questar
            Properties, Inc. ("QPI"), which might not apply to this transaction
            in any event. Nevertheless, to the extent that it is determined that
            a commission or fee is owed to APC, it shall be the obligation of
            the Transferor Corporation and QPI in accordance with the provisions
            of Section 19 hereof. In no event shall any commission be due unless
            and until Closing has occurred and the transactions contemplated
            hereby have been consummated and in no event shall the BRI
            Partnership have any obligation to pay any commission to APC.

     14.02  Loan Prepayment. The Transferor Corporation shall pay any prepayment
            or other penalty and all other amounts required to repay the Loan in
            full at Closing.


                                      -44-

            Offering"), or (ii) a private placement of common stock or other

            Corporation shall supply any documentation and additional

            materials in connection with the Public Offering or the Private

            shall be void and without recourse to all parties except for
            provisions which are expressly stated to survive termination of this
            Agreement.

     17.05  Related Agreements. Simultaneously herewith, the BRI Partnership has
            entered into with various parties various agreements, including this
            Agreement, for the conveyance of partnership interests or property
            interests or other assets and for the making of certain secured
            loans, which



                                      -49-


            agreements are more particularly described on Schedule K attached
            hereto (collectively the "Related Agreements"). (The transactions
            described in the Related Agreements, including this Agreement, are
             collectively the "Related Transactions"). Except to the extent the
            parties expressly agree otherwise in writing or in that certain
            Kickout Agreement of even date between the BRI Partnership and the
            Transferor Agent attached hereto as Exhibit 6 (the "Kickout
            Agreement"), in the event that any of the Related Agreements is
            terminated pursuant to any termination provision of any other
            Related Agreement or does not become effective due to the failure
            of all of the other parties to the Related Agreement to execute
            the Related Agreement on or before September 22, 1997, this
            Agreement shall terminate automatically simultaneously with the
            termination of any such Related Agreement or upon the failure of
            all of the other parties to the Related Agreement to execute the
            Related Agreement on or before September 22, 1997, whereupon this
            Agreement shall be void and without recourse to all parties,
            except for provisions which are expressly stated to survive the
            termination of this Agreement. The Closing under this Agreement
            shall be simultaneous with the closings under the Related
            Agreements. Except as provided in the Kickout Agreement, in the
            event the closing under any of the Related Agreements is
            cancelled or postponed, the Closing under this Agreement shall be
            cancelled or postponed.


                                   SECTION 18

            designate any one or more subsidiary entities, which are wholly
            owned by the BRI Partnership or BRI, to receive title to the
            Property as its designee, provided further that notwithstanding any
            such designation, the BRI Partnership shall continue to remain

                                   SECTION 19

                   ADDITIONAL PROVISIONS RELATING TO TRANSFEROR CORPORATION

     19.01  Intentionally Deleted.

     19.02  Appointment of Agent. Each Transferor Partner hereby appoints the
            Transferor Agent as its agent for the purpose of performing the
            administrative activities to be performed under this Agreement,
            including, without limitation, delivering and receiving notices on
            behalf of the Transferor Partners and the Transferor Partnership,
            preparing the Transferor Allocation Schedule, waiving conditions to
            closing (provided that delivery of the consideration as provided
            herein to the Transferor Partners may not be waived by the
            Transferor Agent) and/or effecting or refraining to effect a
            termination of this Agreement pursuant to the terms hereof and the
            Kickout Agreement, agreeing to extend any of the dates by which
            certain events must occur in accordance with Section 18.11,
            calculation of apportionment amounts under Section 12, electing on
            behalf of the Transferor Partners which pro-rations will be adjusted
            with cash and/or BRI Partnership Units and acting as distribution
            agent with respect to the apportionments and adjustments under
            Section 12 hereof and such other administrative activities as are
            described in this Agreement.

     19.03  Allocation of Transaction Costs. The Transferor Corporation hereby
            acknowledges and agrees that a portion of the amount due to the
            Transferor Corporation will be used to pay the fees and expenses
            attributable to the transaction contemplated by this Agreement. The
            Transferor Corporation hereby agrees that the fees and expenses
            attributable to this transaction will be divided into two
            categories: (i) those fees which can be specifically allocated to
            the Transferor Corporation due to said fees solely benefiting it
            ("Direct Costs") and (ii) those fees which cannot be so allocated
            ("Indirect Costs"). Notwithstanding anything to the contrary
            contained herein, for the proposes of this Section 19.03, the
            Transferor Corporation hereby agrees that: (i) QPI shall be entitled
            to an aggregate administrative fee of $200,000 in connection with
            the concurrent contribution of up to eighteen (18) properties and
            the management companies, as described in the PPM, by the other
            Transferor Partnerships and related entities (collectively, the
            "Related Entities"), which shall be 



                                      -53-


            Indirect Costs; (ii) to the extent it is determined that APC is
            due any fee as described in Section 14.01 hereof, up to
            $1,000,000 of such fee (which may be paid at Closing or held back
            in an escrow account by the Transferor Agent until such time as
            the amount of such fee, if any, is determined) shall be included
            as Indirect Costs, with any such fee in excess of $1,000,000 to
            APC being the sole responsibility of QPI; and (iii) all legal and
            accounting fees of counsel and advisors to the Transferor Agent
            and the Related Entities shall also be Indirect Costs. The
            Transferor Corporation acknowledges and agrees that any and all
            Indirect Costs shall be allocated among the Transferor
            Corporation and the Related Entities at Closing based on the pro
            rata number of BRI Partnership Units allocated at Closing to each
            of them. The Transferor Corporation further acknowledges and
            agrees that the Transferor Agent shall be authorized to determine
            the allocations of the transaction costs and expenses to be
            allocated in accordance with the provisions of this Section 19.03.

     19.04  Power of Attorney. In consideration of the foregoing matters and
            intending to be legally bound hereby, the Transferor Corporation
            hereby irrevocably constitutes and appoints the Transferor Agent
            with unrestricted power of substitution and resubstitution, as the
            attorney-in-fact for the undersigned, coupled with an interest, with
            power and authority to act in its name and on its behalf to execute,
            acknowledge, deliver, swear to, file, or record in the appropriate
            public offices such documents and instruments as may be necessary or
            appropriate in the sole judgment of the Transferor Agent to carry
            out the provisions of this Agreement and the transactions
            contemplated hereby including, without limitation, execution of such
            title affidavits and gap indemnities as are required by the terms of
            this Agreement.

     19.05  Time of Effectiveness. The Transferor Corporation acknowledges and
            agrees that this Agreement and the agreements attached as Exhibits
            hereto will not be binding and effective unless and until all of the
            parties hereto and thereto have executed counterparts to such
            agreements and, to the extent that any agreements or documents
            relating to this Agreement (such as partnership assignments or other
            similar closing documents) are executed prior to the Closing, the
            Transferor Agent is authorized on behalf of the Transferor
            Corporation to hold all such agreements in escrow pending the
            Closing, at which time the Transferor Agent shall be authorized to
            deliver such documents on behalf of the Transferor Corporation to
            the BRI Partnership.

     19.06  Release and Indemnification by and between the Transferor
            Corporation, 



                                      -54-


            the Transferor Agent and certain Affiliates thereof. By executing

            conditions precedent to the transactions contemplated by this
            Agreement set forth in the organizational documents of Transferor
            Corporation, (iii) except as set forth in Schedule 19.06 and
            except as specifically provided herein or in any of the Closing
            documents implementing the transactions contemplated hereby,
            releases the Transferor Agent and Morton Gorn, Stephen Gorn and
            John Colvin and their affiliated entities and spouses
            (collectively, the "GGC Parties") from any and all liability
            arising out of the transactions contemplated hereby and the
            operation of Transferor Corporation prior to the Closing,
            including, but not limited to, all matters relating to the
            management of the property owned by the Transferor Partnership by
            the management company for the Transferor Partnership and any
            affiliated persons or entities thereto, and (iv) agrees, subject
            to the provisions of Section 10.05, to indemnify and hold
            harmless the Transferor Agent and the GGC Parties from and
            against any and all costs, damages, fees, and expenses, including
            reasonable attorney's fees, that the Transferor Agent and/or the
            GGC Parties may incur in carrying out its, his, or their
            responsibilities in good faith and in accordance with the terms
            of this Agreement; provided that the indemnity granted under this
            Section 19.06 shall not extend to any act of gross negligence or
