     On September 25, 1997, Berkshire Realty Company, Inc. (the "Company")
issued 2,737,000 shares of its Series 1997-A Convertible Preferred Stock (the
"Series 1997-A Preferred") in a private placement to Westbrook Real Estate Fund
II, L.P. ("Westbrook") and Morgan Stanley Asset Management resulting in gross
proceeds of approximately $68.4 million (the "Westbrook Transaction"). The
Series 1997-A Preferred will pay a preferred dividend of 9% based on the
purchase price of $25 per share of Series 1997-A Preferred and are convertible
in the aggregate into 5,643,420 shares of Common Stock. Holders of the Series
1997-A Preferred are entitled to vote on an as converted basis, together with
the holders of Common Stock, as one class, on all matters on which the holders
of Common Stock are entitled to vote. Further, the holders of the Series 1997-A
Preferred are entitled to elect one director to the Board of Directors of the
Company. Paul D. Kazilionis, a managing principal and co-founder of Westbrook
Real Estate Partners, L.L.C, the general partner of Westbrook, has been elected
to the Company's Board of Directors by direction of the holders of the Series
1997-A Preferred.

Item 2. Acquisition or Disposition of Assets.

     On September 26, 1997, the Company acquired four multifamily apartment
communities from Citibank for an all-cash purchase price of approximately $60.3
million (the "Citibank Portfolio"). The Citibank Portfolio consists of 1,269
apartment units located within the greater Dallas/Fort Worth, Texas area. The
Company used a significant portion of the proceeds from the Westbrook
Transaction to fund the acquisition. The four properties consist of garden-style
apartment complexes ranging from 232 units to 405 units. Three of the apartment
communities were built in 1984. The fourth property was built in 1996. The
Company is not related to any of the parties involved in this transaction.

     The Company has entered into a definitive agreement with the Questar
Companies ("Questar") to acquire 18 existing apartment communities containing
approximately 3,700 apartment units located in the greater Baltimore area from a
like number of affiliated partnerships and four apartment communities under
development from Questar Builders, Inc. ("Questar Builders"), a company owned by
Stephen M. Gorn but which will remain unaffiliated with the Company following
the acquisition. The Company will also acquire the Questar property management
companies which manage the properties to be acquired as well as certain other
third-party properties and enter into a Development Acquisition Agreement with
Questar Builders, giving the Company the exclusive right to acquire all
apartment projects developed by Questar Builders which meet the Company's
acquisition and development criteria (the foregoing transactions with Questar
collectively, the "Questar Transaction"). Stephen M. Gorn, the President and
Chief Executive Officer of Questar, will become President of the Mid-Atlantic
Division of the Company. The aggregate consideration for the 18 Questar
properties, property management companies and the acquisition of one development
property to be acquired in late 1997 is approximately $181.5 million, comprised
of $20.6 million in operating units of limited partnership of BRI OP Limited
Partnership ("Units"), $4.7 million in common stock of the Company ("Common
Stock"), assumption of $131.7 million in debt and $24.5 million of cash to be
funded by proceeds from the proposed public offering of common stock (the
"Offering"). The Company is not related to any of the parties involved in this
transaction.

     Each of the 18 apartment communities to be acquired from Questar is
presently owned by a single purpose entity (each a "Questar Partnership"). The
holders of interests in the Questar Partnerships (the "Questar Partners") shall
receive Units. The number of Units to be issued to the Questar Partners shall be
determined at the closing of the Questar Transaction based on a formula whereby
a predetermined equity value of an applicable property is divided by the average
of the closing price per share of the Common Stock for the period from August 1,
1997 through the date of closing of the Offering; provided that, in any event,
the amount shall not be less than $10.50 and not greater than $11.75 (subject to
certain adjustments at the date of closing). The Units issuable to certain
members of Stephen Gorn's family shall be restricted as to distributions for a
one-year period from the date of issue. The closing of the Questar Transaction
is contingent on the completion of the Offering. Certain of the contribution
agreements limit the ability of the Company to sell (subject to like-kind
exchanges), refinance or repay existing mortgages (subject to refinancing on
terms which would not affect the tax basis of such Unit recipient(s)) on the
applicable properties for a period of seven years.

     As part of the Questar Transaction, BRI OP Limited Partnership, (the
"Operating Partnership") will make a five-year loan to an entity owned and
controlled by Messrs. Stephen Gorn, Morton Gorn and John Colvin (the "Questar
Borrowers"), in the principal amount of $7.5 million or such lesser amount as
the Questar Borrowers may elect at closing (the "Questar Loan"). The interest
rate shall be determined at the closing by mutual agreement and shall not be
less than prevailing market rates. The Questar Loan shall be secured by the
pledge of Units to be received by the Questar Borrowers and with respect to
Common Stock received by Stephen M. Gorn, a pledge of such stock. Further, the
Operating Partnership is under contract to acquire four apartment development
projects in the greater Baltimore area which are being developed by Questar
Builders or an affiliated entity.

     The Company will acquire the management companies owned by the Gorn family
which manage the 18 apartment communities to be acquired as well as certain
third-party properties for $4.7 million payable in shares of Common Stock based
on the average closing price of such Common Stock for the period August 1, 1997
through the closing of this Offering. The Company expects to enter into separate
five-year employment agreements with each of Stephen M. Gorn and John B. Colvin
and a consulting agreement with Morton Gorn to be entered into at closing. At
closing, the Company expects to execute a five-year lease from the Gorn family
owners, Messrs. Morton Gorn, Stephen Gorn and Colvin, for the approximately
6,900 square feet of space currently occupied by the management companies for a
gross rent of $140,240 per year.

     At closing, Questar Builders and the Operating Partnership expect to enter
into a Development Acquisition Agreement pursuant to which, for a period of five
years, Questar Builders shall grant to the Operating Partnership an exclusive
right to acquire all apartment projects developed by Questar Builders in the
Mid-Atlantic Region which meet the Company's acquisition and development
criteria.

Item 5. Other Events

   On October 15, 1997, the Company filed a prospectus supplement to its Form 
S-3 Registration Statement (No. 333-32565) with the Securities and Exchange
Commission pursuant to which it proposes to offer 10,000,000 shares of common
stock.

Press release dated September 22, 1997:

                   Berkshire Realty Company, Inc. (NYSE-BRI)
                                  NEWS RELEASE
================================================================================


          BERKSHIRE REALTY TO REVISE INTERIM FINANCIAL STATEMENTS WITH
          NO IMPACT TO FUNDS FROM OPERATIONS, DIVIDENDS OR CASH FLOWS

Boston, MA - September 22, 1997 - Berkshire Realty Company, Inc. (NYSE;BRI),
will revise certain interim financial statements for the first six months of
1997 related to the accounting treatment for the issuance of additional
Operating Partnership (OP) Units in conjunction with its March 1, 1996
acquisition of the Company's advisor. The changes will not impact Funds from
Operations (the REIT industry's reporting standard), dividends, liquidity or
cash flows.


    The revisions are the result of recent discussions between the Company and
the staff of the Securities and Exchange Commission, whereby it has been
determined that the assets arising from the acquisitions of the Company's
advisor and property management company are more appropiately reflected as
intangible assets associated with the acquisition of an assembled workforce
rather than goodwill associated with the acquisition of a business. Such
intangible assets will be amortized over a short time frame, generally three
years. A change in the amortization period will occur prospectively beginning in
the third quarter of 1997.


    As a result of the change in the character of the assets acquired, the
Company concluded that the issuance in the first quarter of 1997 of the
additional 109,091 OP Units for the advisor, representing value of $1.2 million,
should be recorded as a non-cash expense rather than an increase in goodwill.
The Company, in revising its financial statements for the periods ended June 30,
1997, will reflect an additional non-cash expense of $1.2 million which will
decrease net income by approximately $962,000 or $.04 per share. There is no
change in Funds from Operations as reported by the Company.


    Berkshire Realty Company, Inc. is a self-administered and self-managed
multifamily equity real estate investment trust. The Company's portfolio
consists of 41 apartment communities with 13,509 apartment units (located
primarily in Texas, the Southeast, Florida and the mid-Atlantic), and a small
remaining retail portfolio.

                          Independent Auditors' Report

The Board of Directors
CREEF Sweetwater Ranch, Inc.,
CREEF H. Brook Corp.,
CREEF H Ridge Corp.

The Partners DMC Huntington Lakes Apartments, L.P.:

We have audited the accompanying combined statement of revenue over certain
operating expenses of the Citibank Portfolio (the "Properties") for the year
ended December 31, 1996. This financial statement is the responsibility of the
Properties' management. Our responsibility is to express an opinion on this
combined financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the combined statement of revenue over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis 
for our opinion.

The accompanying combined statement of revenue and certain operating expenses
was prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission, and excludes certain expenses, described in note 2, and
therefore is not intended to be a complete presentation of the Properties'
revenue and expenses.

In our opinion, the combined statement referred to above presents fairly, in all
material respects, the revenue over certain operating expenses (as described in
note 2) of the Citibank Portfolio for the year ended December 31, 1996, in
conformity with generally accepted accounting principles.

(2) Basis of Presentation

    The combined statement has been prepared on the accrual method of
    accounting. The Properties were previously owned by Citibank, an unrelated
    party.

    The Combined Statement has been prepared in accordance with Rule 3-14 of
    Regulation S-X of the Securities and Exchange Commission for real estate
    properties acquired or to be acquired. Accordingly, this statement excludes
    certain historical expenses not comparable to the operations of the
    Properties after acquisition such as amortization, depreciation, property
    management fees, corporate expenses and other costs not directly related to
    the future operations of the Properties.

(3) Significant Accounting Policies

    Rental Revenue

    Rental income attributable to residential rental agreements is recorded on
    the accrual method as earned. Apartment units are generally rented under
    lease agreements with terms of one year or less.

    Unaudited Interim Information

    The combined statement of revenue over certain operating expenses for the
    period from January 1, 1997 through June 30, 1997 is unaudited. In the
    opinion of management, all adjustments consisting only of normal recurring
    adjustments, considered necessary for a fair presentation for such period
    has been made. Results for interim periods should not be considered or
    indicative for results for a full year. Footnote disclosure normally
    included in annual financial statements prepared in accordance with
    generally accepted accounting principles have been omitted herein with
    respect to the interim financial data. The interim information herein should
    be read in conjunction with the annual financial information presented
    herein.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of Berkshire Realty Co., Inc.:

We have audited the accompanying combined statement of revenue over certain
operating expenses of the Questar Portfolio (the "Properties") for the year
ended December 31, 1996. This statement is the responsibility of the Properties'
management. Our responsibility is to express an opinion on this combined
statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the combined statement of revenue over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

The accompanying combined statement of revenue over certain operating expenses
was prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission, and excludes certain expenses described in Note 2, and
therefore is not intended to be a complete presentation of the Properties'
revenues and expenses.

In our opinion the combined financial statement referred to above presents
fairly, in all material respects, the revenue over certain operating expenses
(as described in Note 2) of the Questar Portfolio for the year ended December
31, 1996 in conformity with generally accepted accounting principles.

     NOTES TO COMBINED STATEMENT OF REVENUE OVER CERTAIN OPERATING EXPENSES


   The Combined Statement has been prepared in accordance with Rule 3-14 of
   Regulation S-X of the Securities and Exchange Commission for real estate
   properties acquired or to be acquired. Accordingly, this statement excludes
   certain historical expenses not comparable to the operations of the
   properties' after acquisition such as amortization, depreciation, certain
   interest expense (Note 4), corporate expenses and certain other costs not
   directly related to the future operations of the Properties.

3. Significant Accounting Policies:
   -------------------------------

   Rental Revenue

   Rental income attributable to residential rental agreements is recorded on
   the accrual method as earned. Apartment units are generally rented under
   lease agreements with terms of one year or less.

   Unaudited Interim Information

   The combined statement of revenue over certain operating expenses for the
   period from January 1, 1997 through June 30, 1997 is unaudited. In the
   opinion of management, all adjustments necessary for a fair presentation of
   such combined statement have been included. The results of operations for the
   period are not necessarily indicative of the Properties' future results of
   operations.

   Risks and Uncertainties

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of revenues and expenses during the
   reporting period. Actual results could differ from those estimates.

4. Debt Assumption:
   ---------------

   Debt to be Outstanding Subsequent to Acquisition

   In connection with the acquisition Berkshire will assume certain mortgage
   notes encumbering certain of the Properties of approximately $132,079 at
   December 31, 1996. Berkshire's assumption of these mortgage notes does not
   provide for any modification to the original terms; therefore, interest
   expense incurred prior to Berkshire's assumption of the respective mortgage

     NOTES TO COMBINED STATEMENT OF REVENUE OVER CERTAIN OPERATING EXPENSES


   notes is representative of future interest expense. Accordingly, interest
   expense of $10,323 for 1996 and $4,712 for the six months ended June 30, 1997
   (unaudited) is recognized in the accompanying Combined Statement. The
   mortgage notes are generally due in monthly installments and mature at
   various dates through 2035. Interest rates on the notes vary from 6.37% to
   9.50%. Certain mortgage notes payable are subject to prepayment penalties of
   varying amounts in the event of an early principal repayment.

   Principal payments due on the mortgage notes during the next five years are
   approximately as follows:

   1997                                         $10,840
   1998                                           1,019
   1999                                           1,095
   2000                                           1,177
   2001                                           1,268

   Debt to be Repaid or Modified

   Berkshire, as part of the acquisition of certain properties, will pay off
   certain  mortgage notes encumbering certain of the Properties with a balance
   of approximately $15,708 at December 31, 1996.  Therefore, on a continuing 
   basis, interest expense will not be incurred related to these mortgage notes.
   Accordingly, interest expense related to these mortgage notes is not 
   recognized in the accompanying Combined Statement.

December 31, 1995. This financial statement is the responsibility of the
Properties' management. Our responsibility is to express an opinion on this
combined financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the combined statement of revenue over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

The accompanying combined statement of revenue and certain operating expenses
was prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission, and excludes certain expenses, described in Note 2, and
therefore is not intended to be a complete presentation of the Properties'
revenue and expenses.

In our opinion, the combined financial statement referred to above presents
fairly, in all material respects, the revenue over certain operating expenses
(as described in Note 2) of the Merit Portfolio for the year ended December 31,
1995, in conformity with generally accepted accounting principles.

1. Description of Properties:
   --------------------------

   The accompanying combined statement of revenue over certain operating
   expenses ("the Combined Statement") includes the combined operations of
   five multi-family properties (collectively, the "Properties" or "Merit
   Portfolio") which were acquired by Berkshire Realty Company, Inc.
   ("Berkshire") from an unrelated third-party. The apartment communities
   which were acquired are summarized as follows:

Property Name                Date Acquired      Location         Number of Units
- -------------                -------------      --------         ---------------

                                                                     =====

2. Basis of Presentation:
   ----------------------

   The Combined Statement has been prepared on the accrual basis.

   The Combined Statement has been prepared in accordance with Rule 3-14 of
   Regulation S-X of the Securities and Exchange Commission for real estate
   properties acquired or to be acquired. Accordingly, this statement excludes
   certain historical expenses not comparable to the operations of the
   properties after acquisition such as amortization, depreciation, asset and
   property management fees, corporate expenses and other costs not directly
   related to the future operations of the Properties.

3. Significant Accounting Policies:
   -------------------------------

   Rental Revenue
   --------------

   Rental income attributable to residential rental agreements is recorded on
   the accrual method as earned. Apartment units are generally rented under
   lease agreements with terms of one year or less.

   Unaudited Interim Information
   -----------------------------

   The combined statement of revenue over certain operating expenses for the
   period from January 1, 1996 through dates of acquisition is unaudited. In the
   opinion of management all adjustments necessary for a fair presentation of
   such combined statement have been included. The results of operations for the
   period are not necessarily indicative of the Properties' future results of
   operations.

   Risks and Uncertainties
   -----------------------

   The preparation of statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of revenues and expenses during the
   reporting period. Actual results could differ from these estimates.

4. Debt Assumption:
   ---------------

   In connection with the acquisition, Berkshire will assume certain mortgage
   notes encumbering the Merit Portfolio of approximately $12,106. The
   assumption of these mortgage notes does not provide for any modification to
   the original terms, therefore, interest expense incurred prior to Berkshire's
   assumption is representative of future interest expense. Accordingly,
   interest expense of $623 for 1995 and $515 for the period January 1, 1996
   through dates of acquisition (unaudited) is recognized in the accompanying
   Combined Statement. The mortgage notes are generally due in monthly
   installments and mature at various dates through 2005. Interest rates on the
   notes vary from 5.775% to 7.695%. Certain mortgage notes payable are subject
   to repayment penalties of varying amounts in the event of an early principal
   repayment.

   Principal payments due on the mortgage notes during the next five years are
   approximately as follows:


   1996       $299
   1997        326
   1998        331
   1999        336
   2000        342

                      REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders
of Berkshire Realty Co., Inc.:

We have audited the accompanying statement of revenue over certain operating
expenses of Westchester West Apartments (the "Property") for the year ended
December 31, 1996. This statement is the responsibility of the Property's
management. Our responsibility is to express an opinion on this statement based
on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of revenue over certain operating expenses
is free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statement. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our
opinion.

The accompanying statement of revenue over certain operating expenses was
prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission, and excludes certain expenses described in Note 2, and
therefore is not intended to be a complete presentation of the Property's
revenue and expenses.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the revenue over certain operating expenses (as described
in Note 2) of Westchester West Apartments for the year ended December 31, 1996
in conformity with generally accepted accounting principles.

1.   Description of Property:
     ------------------------

     The accompanying statement of revenue over certain operating expenses (the
     "Statement") includes the operations of a 345-unit apartment community (the
     "Property") which was acquired on January 1, 1997 by Berkshire Realty
     Company, Inc. ("Berkshire") from an unrelated third party. The Property is
     located in Silver Spring, Maryland.

     The Statement has been prepared on the accrual method of accounting.

     The Statement has been prepared in accordance with Rule 3-14 of Regulation
     S-X of the Securities and Exchange Commission for real estate properties
     acquired or to be acquired. Accordingly, this statement excludes certain
     historical expenses not comparable to the operations of the property after
     acquisition such as amortization, depreciation, property management fees,

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders
of Berkshire Realty Co., Inc.:

We have audited the accompanying combined statement of revenue over certain
operating expenses of the SunChase Apartments and Polos West Apartments (the
"Properties") for the year ended December 31, 1996. This statement is the
responsibility of the Properties' management. Our responsibility is to express
an opinion on this combined statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the combined statement of revenue over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

The accompanying combined statement of revenue over certain operating expenses
was prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission, and excludes certain expenses described in Note 2, and
therefore is not intended to be a complete presentation of the Properties'
revenues and expenses.

In our opinion the combined financial statement referred to above presents
fairly, in all material respects, the revenue over certain operating expenses
(as described in Note 2) of the Sunchase Apartments and Polos West Apartments
for the year ended December 31, 1996 in conformity with generally accepted
accounting principles.

     NOTES TO COMBINED STATEMENT OF REVENUE OVER CERTAIN OPERATING EXPENSES

                             (dollars in thousands)


1.   Description of Properties:
     --------------------------

     The accompanying combined statement of revenue over certain operating
     expenses (the "Combined Statement") includes the combined operations of
     SunChase Apartments and Polos West Apartments (collectively the
     "Properties") which were acquired by Berkshire Realty Company, Inc.
     ("Berkshire"), from an unrelated third party on May 12, 1997. The apartment
     communities are summarized as follows:

     Property Name            Location            Number of Units
     -------------            --------            ---------------
     SunChase                 Bradenton, FL             168
     Polos West               Winter Garden, FL         200
                                                        ---
                                                        368
                                                        ===


2.   Basis of Presentation:
     ----------------------


     The Combined Statement has been prepared on an accrual basis.

   The Combined Statement been prepared in accordance with Rule 3-14 of
   Regulation S-X of the Securities and Exchange Commission for real estate
   properties acquired or to be acquired. Accordingly, this statement excludes
   certain historical expenses not comparable to the operations of the
   properties' after acquisition such as amortization, depreciation, certain
   interest expense (Note 4), corporate expenses and certain other costs not
   directly related to the future operations of the Properties.


3.   Significant Accounting Policies:
     --------------------------------

     Rental Revenue

     Rental income attributable to residential rental agreements is recorded on
     the accrual method as earned. Apartment units are generally rented under
     lease agreements with terms of one year or less.

     NOTES TO COMBINED STATEMENT OF REVENUE OVER CERTAIN OPERATING EXPENSES

                             (dollars in thousands)


     Unaudited Combined Statement

     The combined statement of revenue over certain operating expenses for the
     period from January 1, 1997 through May 12, 1997 (date of acquisition) is
     unaudited. In the opinion of management, all adjustments necessary for a
     fair presentation of such combined statement have been included. The
     results of operations for the period are not necessarily indicative of the
     Properties' future results of operations.

     Risks and Uncertainties

     The preparation of statements in conformity with generally accepted
     accounting principles requires management to make estimates and assumptions
     that affect the reported amounts of revenue and expenses during the
     reporting period. Actual results could differ from those estimates.


4.   Debt Assumption:
     ----------------

     In connection with the acquisition, Berkshire will assume a mortgage note
     encumbering Polos West Apartments of approximately $5,719. The assumption
     of this mortgage note does not provide for any modification to the original
     terms, therefore, interest expense incurred prior to Berkshire's assumption
     is representative of future interest expense. Accordingly, interest expense
     of $435 for 1996 and $157 for the period January 1, 1997 to May 12, 1997 
     (unaudited), is included in the accompanying combined statement. The
     mortgage note, which has an interest rate of 7.45%, is due in monthly
     installments and matures in December 2003.

     Principal payments due on the mortgage notes during the next five years are
     approximately as follows:

     1997      $144
     1998       155
     1999       167
     2000       180
     2001       193

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of Berkshire Realty Co., Inc.:

We have audited the accompanying combined statement of revenue over certain
operating expenses of the Emerald Portfolio (the "Properties") for the year
ended December 31, 1996. This statement is the responsibility of the Properties'
management. Our responsibility is to express an opinion on this combined
statement based on our audit.

We conducted an audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the combined statement of revenue over certain operating
expenses is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the statement. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

The accompanying combined statement of revenue over certain operating expenses
was prepared for the purpose of complying with Rule 3-14 of the Securities and
Exchange Commission, and excludes certain expenses described in Note 2, and
therefore is not intended to be a complete presentation of the Properties'
revenues and expenses.

In our opinion the combined financial statement referred to above presents
fairly, in all material respects, the revenue over certain operating expenses
(as described in Note 2) of the Emerald Portfolio for the year ended December
31, 1996 in conformity with generally accepted accounting principles.

     The Combined Statement has been prepared in accordance with Rule 3-14 of

     properties acquired or to be acquired. Accordingly, this statement excludes
     certain historical expenses not comparable to the operations of the
     properties' after acquisition such as amortization, depreciation, property

     operations for the period are not necessarily indicative of the Properties'
     future results of operations.

     Risks and Uncertainties

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

4.   Debt Assumption:
     ----------------

     In connection with the acquisition, Berkshire will assume mortgage notes
     encumbering the Properties of approximately $15,365 at December 31, 1996.
     Berkshire's assumption of these mortgage notes does not provide for any
     modification to the original terms; therefore, interest expense incurred
     prior to Berkshire's assumption of the respective mortgage notes is
     representative of future interest expense. Accordingly, interest expense of
     $1,447 for 1996 and $712 for the six months ended June 30, 1997 (unaudited)
     is recognized in the accompanying Combined Statement. The mortgage notes
     are generally due in monthly installments and mature at various dates
     through 2023. Interest rates on the notes are at 7.5%.

     Principal payments due on the mortgage notes during the next five years are
     approximately as follows:

          1997                          $264
          1998                           284

     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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership

Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the

Transferor Partnership 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.

(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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 

                                       -6-

<PAGE>



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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income 

                                       -7-

<PAGE>



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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.


                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $5,859,308, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated August 3, 1984,
as amended through the Fourth Allonge Deed of Trust Note dated as of January 25,
1994, in the original principal amount of $4,628,300 (the "Note") evidencing the
loan (the "Loan") made to the Transferor Partnership by CPC Mortgage Capital,
LLC ("Lender") and secured by the Loan Documents which shall be an obligation of
the Transferor Partnership as of the Closing subject to any exculpation from
liability provisions therein.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted 

                                       -8-

<PAGE>



Distribution BRI Partnership Units are collectively referred to herein as the
"BRI Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or
liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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 


                                      -9-


<PAGE>



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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

     (f) Such Transferor Partner 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

     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, 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

     contained in the foregoing legend.

Partner's principal residence or principal place of business, and such
Transferor Partner has no present intention of becoming a resident of any
country, state or jurisdiction other than the country and state in which such

     (d) the provisions of this Section 10.03 shall survive the Closing
indefinitely.

     10.05 Indemnification.

     (a) The Transferor Partners' Indemnity. In the event the parties proceed to
Closing, each Transferor Partner agrees, severally and not jointly, to indemnify
and hold the BRI Partnership harmless against and with respect to (i) any loss
or damage (including reasonable attorney's fees) to the BRI Partnership
subsequent to the Closing Date, resulting from (A) any inaccuracy in or breach
of any representation or warranty of the Transferor Partnership set forth in
Section 5A or of such Transferor Partner set forth in Section 5B or (B)
resulting from any breach or default by the Transferor Partnership or such
Transferor Partner of any obligation of the Transferor Partnership or such
Transferor Partner under this Agreement or (ii) from liabilities for borrowed
money (other than the payments under the Loan due after the Closing) incurred by
the Transferor Partnership or the Property prior to the Closing; provided that
no Transferor Partner shall be required to indemnify the BRI Partnership for any
amounts in excess of 50% of the fair market value of the BRI Partnership Units
received by such Transferor Partner as of the date such indemnification
obligation is satisfied (except for indemnification obligations with respect to
representations of each of the Transferor Partners in Section 5.34, which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner) (collectively, the "Cap"); and provided further that to the extent any
of the Transferor Partners have any indemnification obligation to the BRI
Partnership, the Transferor Partners may elect to satisfy such indemnification
obligation by directing the BRI Partnership to cancel such amount of BRI
Partnership Units acquired by such Transferor Partner pursuant to this Agreement
having a fair market value (measured at the time such BRI Partnership Units are
returned or cancelled) equal to the indemnification obligation of such
Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including
reasonable attorney's fees) to the Transferor Partners, subsequent to the
Closing Date, resulting from (A) any inaccuracy in or breach of any
representation or warranty of the BRI Partnership or (B) resulting from any
breach or default by the BRI Partnership of any obligation of the BRI
Partnership under this Agreement or (ii) from liabilities of the Transferor
Partnership or the Property after the Closing (except for such liabilities
resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor 



                                      -40-


<PAGE>



Partner under Section 10.05(b)(i) for any amounts in excess of 50% of the fair
market value as of the date such indemnification obligation is satisfied of the
BRI Partnership Units received by such Transferor Partner (except for
indemnification obligations with respect to Sections 6.10 and 11.03 which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner).

     (c) The indemnification obligations of the Transfer Partners and the BRI
Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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 any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section


                                      -41-


<PAGE>



708(b)(1)(B) of the Code and its tax year shall close on the Closing Date. The
Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be
filed by or on behalf of the Transferor Partnership with respect to all tax
years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,
which shall not be unreasonably withheld or delayed. The BRI Partnership shall
assist the Transferor Agent in obtaining such data and information regarding the
Transferor Agent to permit the Transferor Partnership to prepare such returns or
to respond to any audits or assessments for the periods covered by such returns.


                                   SECTION 11

     11.02 Partnership's Expenses. The BRI Partnership shall pay its own counsel
fees, and all loan assumption fees (not to exceed 1% of the outstanding loan
balance) and one-half of all (i) Title Insurance and Survey costs, (ii) escrow
and recording costs and (iii) transfer taxes and documentary stamps, if any, and
(iv) UCC search costs.

     11.03 Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Partners, in their
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Partnership has not dissolved, terminated or liquidated, the right to
receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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 


                                      -44-


<PAGE>



to allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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:


                                      -45-


<PAGE>



     (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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor 



                                      -46-


<PAGE>



Partner, and (iii) the number of the Restricted Distribution BRI Partnership
Units to be received by each Transferor Partner. The BRI Partnership shall have
no obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the 



                                      -47-


<PAGE>



Transferor Partners to adjust for such amounts owing by the Transferor Partners
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 Partners,
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 Partners 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 Partnership shall have elected to settle
adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such distribution of surplus cash
relates only to the period prior to the Closing Date, all such surplus cash
shall be distributed to the Transferor Partners prior to Closing; provided
however, if as a result of the 1997 annual HUD audit (it being agreed that the
BRI Partnership shall consult with the Transferor Agent during the HUD audit
procedure), HUD (after final adjudication by regulatory and judicial
authorities) determines that all or any portion of such distribution of surplus
cash to the Transferor Partners was improper, the Transferor Partners,
severally, agree to reimburse the Transferor Partnership immediately upon demand
for all amounts so designated by HUD as improper and to indemnify, defend and
hold the Transferor Partnership and the BRI Partnership harmless from and
against all loss, cost, damage or expense (including reasonable legal fees)
suffered or incurred as a result of such improper distribution of surplus cash.
In all other cases, there shall be no adjustment at Closing regarding surplus
cash, but at such time as HUD approves the distribution of surplus cash for
fiscal 1997, the BRI Partnership shall receive all such surplus cash and
thereafter the BRI Partnership shall promptly pay to the Transferor Agent, as
distribution agent for the Transferor Partners, the Transferor Partners pro-rata
share of such surplus cash allocable to the period prior to the Closing Date.


                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled 



                                      -48-


<PAGE>



closing the Transferor Partnership Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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 Transferor Partnership Interests in accordance with the terms of
this Agreement and the Transferor Partners willfully refuse to perform the
Transferor Partners' obligations hereunder, the BRI Partnership, at its option,
shall have the right to compel specific performance by the Transferor Partners
hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to 



                                      -49-


<PAGE>



compel specific performance by the BRI Partnership hereunder, in which event the
Transferor Partners 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 Partners in connection with the exercise of their
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
Partners in the event of a default by the BRI Partnership in lieu of all other
rights and remedies which the Transferor Partners may have against the BRI
Partnership at law or in equity.


                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

<PAGE>



Transferor Partners, to the transfer of ownership of the Transferor Partnership
to the BRI Partnership and to obtain the Lender Estoppel Letter. The Transferor
Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership and the transfer of
ownership of the Transferor Partnership to the BRI Partnership. The BRI
Partnership shall supply any and all documentation and additional information
required by Lender in order to promptly complete the request for the consent of
Lender to the transactions contemplated hereunder. The Transferor Partnership
shall request that Lender state in writing any terms and requirements, including
the amount of any Loan Assumption Fees, to be imposed by Lender in connection
with its consent to the transactions contemplated hereby. It shall be a
condition of Closing that prior to October 15, 1997, Lender shall have granted
its consent to the transactions contemplated hereunder on terms and requirements
reasonably satisfactory to the BRI Partnership, shall have issued the Lender
Estoppel Letter and shall have agreed to release the Transferor Partners from
all liability under the Loan Documents. In the event that any of the terms or
requirements required by Lender for its consent are not approved by the BRI
Partnership, the BRI Partnership may terminate this Agreement by written notice
given to the Transferor Partners within fifteen (15) business days after the BRI
Partnership have received in writing the terms and requirements of Lender for
its consent. In the event either (a) the consent of Lender is not obtained prior
to the Closing or (b) the BRI Partnership does not approve the terms and
conditions of Lender, including the amount of any Loan Assumption Fees in excess
of 1% of the unpaid principal balance, and the BRI Partnership gives timely
notice of termination hereunder to the Transferor Agent, this Agreement shall
terminate without further action by any party, and, thereafter this Agreement
shall be void and without recourse to all parties, except for provisions which
are expressly stated to survive termination of this Agreement. In the event the
Lender shall not have agreed to release the Transferor Partners from all
liability under the Loan Documents or the Lender shall have placed terms and
conditions on the Transferor Partners that are unacceptable to them, the
Transferor Agent may terminate this Agreement by written notice given to the BRI
Partnership within fifteen (15) business days after the Transferor Agent has
received in writing notice that the Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions. If the Transferor Agent gives timely notice
of termination to the BRI Partnership, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of



                                      -55-


<PAGE>



common stock or other equity securities of BRI (the "Public Offering"), or (ii)
a private placement of common stock or other equity securities of BRI (the
"Private Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI 


                                      -56-


<PAGE>



Partnership will not take possession of the Transferor Partnership or the
Property nor assume the burdens and benefits of project ownership prior to such
approval by HUD.

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives 



                                      -57-


<PAGE>



timely notice of termination hereunder to the Transferor Partners, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

                        ADDITIONAL PROVISIONS RELATING TO
                             THE TRANSFEROR PARTNERS

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

conditions to closing (provided that delivery of the consideration as provided

                                      -60-


<PAGE>



Transferor Partners pursuant to the terms of this Agreement. Each Transferor
Partner and the Transferor Partnership 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 Partnership 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, each of the Transferor
Partners 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 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. Each of the Transferor
Partners acknowledges and agrees that (i) any and all Direct Costs shall be
allocated based on the pro rata number of BRI Partnership Units allocated to
each of them with respect to their interest in the Transferor Partnership and
(ii) any and all Indirect Costs shall be allocated among the Transferor Partners
and the Related Entities at Closing based on the pro rata number of BRI
Partnership Units allocated at Closing to each of them. Each of the Transferor

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners

                                      -3-
<PAGE>

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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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, a non-imputation
endorsement, a fairways 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of 


                                      -4-
<PAGE>

(A) ten (10) days after the Transferor Partnership 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 Partnership
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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to 


                                      -5-
<PAGE>

cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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


                                      -6-
<PAGE>

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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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


                                      -7-
<PAGE>

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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.


                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $2,608,723, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of CPC Mortgage
Capital, LLC, as successor to Maryland National Mortgage Corporation ("Lender"),
securing the outstanding principal balance of the Note dated October 18, 1989,
in the original principal amount of $2,250,000 (the "Note") evidencing the loan
(the "Loan") made to the Borrower Partnership by Lender. The Loan is also
secured by the other Loan Documents (as defined in Section 5.20 hereof) which
shall be an obligation of the Borrower Partnership and the Transferor
Partnership as of the Closing subject to any exculpation from liability
provisions therein. The Transferor Partnership shall also 


                                      -8-
<PAGE>

remain as obligor of the outstanding principal balance of the note dated October
19, 1989 in the original principal amount of the Note (the "Borrower Partnership
Note"), evidencing the loan made to the Transferor Partnership by the Borrower
Partnership (the "Borrower Partnership Loan").

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner 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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership
owes any amounts to the Transferor Partners 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 each Transferor Partner pursuant to Section 12.04. The
Transferor Agent shall be liable to distribute the BRI Partnership Units and if
applicable, a pro-rata share of the BRI Additional Payment to each of the
Transferor Partners in accordance with the Transferor Allocation Schedule. The
BRI Partnership shall have no obligation or liability with respect to the
preparation or accuracy of the Preliminary Transferor Allocation Schedule or the
Transferor Allocation Schedule or the distribution of the BRI Partnership Units
or the BRI Additional 


                                      -9-
<PAGE>

Payment, if applicable, to the Transferor Partners and the Transferor Partners
hereby release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners in the event of a
decrease or increase in the market


                                      -10-
<PAGE>

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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

                                    SECTION 3

Transferor Partnership 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

referred to in the Commitment in reliance on the execution by the Transferor
Agent pursuant to a Power of Attorney for all Transferor Partners 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 Partners. It is agreed that time is of the
essence of this Agreement.

<PAGE>

     (a) Such Transferor Partner 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

be issued to each Transferor Partner 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

predicated in part on the accuracy and completeness of the representations and
warranties of such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons

(and which opinion and counsel shall be reasonably acceptable to both the BRI

accordingly, such Transferor Partner 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.
Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such that it is able to bear all risks of the

(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) Such Transferor Partner 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

               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

               will be exempt from registration under the Act and its applicable

contract to which the Borrower Partnership is a party, and to the Transferor
Partnership's knowledge the Borrower Partnership is not in violation of any
order, statute, rule or regulation applicable to it, except for such violations
which would not have a Material Adverse Effect. Neither the execution, delivery
and performance of this Agreement by the Transferor Partnership, nor the
contribution of the Transferor Partnership Interests by the Transferor Partners
hereunder, nor the assignment and transfer of the Borrower General Partnership
Interest by the Borrower Corporate General Partner to the Borrower LLC General
Partner will result in any Material Adverse Effect or be in conflict with or
constitute a default under the Borrower Partnership Agreement or result in the
creation of any mortgage, pledge, lien, encumbrance or charge upon any of the
properties or assets of the Borrower Partnership.

     5.39 Partnership Capitalization. The Borrower Partnership Agreement (i) is
the only agreement among the partners thereto relating to the organization,

contribution required to be paid by it pursuant to the Borrower Partnership
Agreement. A true, correct and complete copy of the Borrower Partnership
Agreement is attached hereto as Exhibit IX. The Borrower Partnership has no
commitment to issue any right to purchase or acquire or to issue or distribute
to the partners thereof any evidences of indebtedness or assets; and the

or otherwise hold any interest in, any assets other than the Borrower
Partnership Loan to the Transferor Partnership.

     5.43 License; Permits; etc. Except for licenses, permits or authorizations
previously obtained by the Borrower Partnership, no other material license,
permit or authorization is necessary to own and operate the Borrower
Partnership's business as such is presently conducted and neither the conduct of
the Borrower Partnership's business nor any material portion thereof is
dependent on the issuance or obtaining of any other license, permit or
authorization.

     5.44 Liabilities. Except for the Loan, the Borrower Partnership has no
indebtedness for borrowed money and the Borrower Partnership has not, directly
or indirectly, created, incurred, assumed or guaranteed or otherwise become

defaults on the Loan after Closing. The Borrower Partnership has conducted its
business only in the ordinary course and, except for the Loan and the Borrower

Partnership has not created, permitted or allowed any mortgage, pledge, lien,
security interest, encumbrance, restriction or charge of any kind with respect
to any of its properties, businesses or assets.

of the Transferor Partnership, such Transferor Partner or the Borrower Corporate
General Partner under this Agreement or (ii) from liabilities for borrowed money
(other than the payments under the Loan due after the Closing) incurred by the
Transferor Partnership, the Borrower Partnership, the Borrower Corporate General
Partner or the Property prior to the Closing; provided that no Transferor
Partner shall be required to indemnify the BRI Partnership for any amounts in
excess of 50% of the fair market value of the BRI Partnership Units received by
such Transferor Partner as of the date such indemnification obligation is
satisfied (except for indemnification obligations with respect to
representations of each of the Transferor Partners in Section 5.34, which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner) (collectively, the "Cap"); and provided further that to the extent any
of the Transferor Partners have any indemnification obligation to the BRI
Partnership, the Transferor Partners may elect to satisfy such indemnification
obligation by directing the BRI Partnership to cancel such amount of BRI
Partnership Units acquired by such Transferor Partner pursuant to this Agreement

returned or cancelled) equal to the indemnification obligation of such
Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including

Closing Date, resulting from (A) any inaccuracy in or breach of any
representation or warranty of the BRI Partnership or (B) resulting from any
breach or default by the BRI Partnership of any obligation of the BRI
Partnership under this Agreement or (ii) from liabilities of the Transferor
Partnership or the Property after the Closing (except for such liabilities
resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor


                                      -47-
<PAGE>

Partner under Section 10.05(b)(i) for any amounts in excess of 50% of the fair
market value as of the date such indemnification obligation is satisfied of the
BRI Partnership Units received by such Transferor Partner (except for
indemnification obligations with respect to Sections 6.10 and 11.03 which shall
be limited to 100% of the fair market value as of the date such indemnification

     (c) The indemnification obligations of the Transfer Partners and the BRI
Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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 any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section

                                      -48-

     (c) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments, or except as contemplated in Section
11.04 hereof, or as otherwise required by the holder of the Loan under the Loan
Documents, or change the terms in a manner that would change the Loan from
nonrecourse to recourse within the meaning of Section 752 of the Code and the
regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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


                                      -52-
<PAGE>

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.

     11.04 Post-Closing Refinancing. Notwithstanding the provisions of Section
11.03(c) hereof, the BRI Partnership and BRI shall cause the Transferor
Partnership within 90 days after the Closing Date to refinance the Loan with a
new non-recourse loan (the "New Loan") for an amount not less than $1,820,000
for a term not less than seven years, for an interest rate not to exceed that
available under the Tier 2 FNMA Underwriting Guidelines and upon such other
terms and conditions as may be satisfactory to the BRI Partnership and BRI. The
Transferor Partners shall pay all costs and expenses incurred by the Transferor
Partnership, the BRI Partnership or BRI in connection with such refinancing,
including, without limitation, loan origination fees, lender legal fees and all
other expenses charged by the refinancing lender and the Transferor
Partnership's, the BRI Partnership's or BRI's attorneys' fees and costs
(collectively, "Refinancing Costs"), but excluding any escrow required to be
established with the refinancing lender and the cost of any repairs or
replacements required by the refinancing lender. At Closing, the Transferor
Partners shall deposit in escrow a sum (the "Refinancing Escrow Amount") equal
to the lesser of (a) two (2%) percent of the principal amount of the New Loan as
estimated by the BRI Partnership at the time of Closing (but in any event not
more than $36,400), or (b) an amount mutually agreed to by the Transferor Agent
and the BRI Partnership, with a mutually acceptable escrow agent and pursuant to
a mutually acceptable escrow agreement. The Refinancing Escrow Amount shall be
used to pay for the Refinancing Costs. The amount to be deposited by each
Transferor Partner shall be proportionate to the number of BRI Partnership Units
to be received by each Transferor Partner at Closing in accordance with the
Transferor Allocation Schedule. In the event that the actual Refinancing Costs
are less than the Refinancing Escrow Amount, the difference shall be refunded to
the Transferor Agent who shall distribute such refund to the Transferor Partners
in 


                                      -53-
<PAGE>

proportion to their respective contributions to the Refinancing Escrow Amount.
Once the Loan is refinanced under this Section, the provisions of Section
11.03(c) shall apply to the New Loan as fully and completely as if all
references in Section 11.03(c) to the Loan instead referred to the New Loan and
all references to the Loan shall be deemed to refer to the New Loan.

                                   SECTION 12

                 APPORTIONMENTS AND ADJUSTMENTS TO CONSIDERATION

     12.01 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 the provisions of 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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 


                                      -54-
<PAGE>

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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transferor Allocation Schedule (the "Transferor Allocation Schedule"), which
shall be based upon the Preliminary Transferor Allocation Schedule, shall
incorporate all adjustments and prorations to be made pursuant to Section 12,
and shall set forth (i) the name of each Transferor Partner, (ii) the number of
Unrestricted Distribution BRI Partnership Units to be received by each
Transferor Partner, and (iii) the number of Restricted Distribution BRI
Partnership Units to be received by each Transferor Partner. The BRI Partnership
shall have no obligation or liability with respect to the preparation or
accuracy of the Preliminary Transferor Allocation Schedule or the Transferor
Allocation Schedule or the distribution of the BRI Partnership Units or the BRI
Additional Payment, if applicable, to the Transferor Partners and the Transferor
Partners hereby release the BRI Partnership from any such obligation or
liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners or the BRI Partnership after the
Closing are payable 


                                      -55-
<PAGE>

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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01 and the escrow required to be
established under Section 11.04, the Transferor Partners owe an amount to the
BRI Partnership or into escrow, the Transferor Partnership shall have the right
to elect on behalf of the Transferor Partners to adjust for such amounts owing
by the Transferor Partners to the BRI Partnership or the escrow 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and the
Property in its then condition


                                      -56-
<PAGE>

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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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 Transferor Partnership Interests in accordance with the terms of
this Agreement and the Transferor Partners willfully refuse to perform the
Transferor Partners' obligations hereunder, the BRI Partnership, at its option,
shall have the right to compel specific performance by the Transferor Partners
hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The Transferor Partners will pay any assumption
or transfer fee and other related costs and expenses required by Lender (the

and the transfer of the ownership of the Transferor Partnership to the BRI
Partnership subject to the Notes and other Loan Documents as contemplated
hereby.

     In the event that any condition set forth in Section 17.02(a) through

Agent in writing, on or before the Closing Date, the Transferor Partners shall

its interests in the Borrower Partnership to the Borrower LLC General Partner,
to the withdrawal from the Borrower Partnership of the Borrower Corporate
General Partner, and to the admission to the Borrower Partnership of the
Borrower LLC General Partner as a fifty percent (50%) general partner, and to
obtain the Lender Estoppel Letter. The Transferor Partnership, with the BRI
Partnership's cooperation, shall immediately commence to obtain the consent of
Lender necessary to permit the contribution of the Transferor Partnership
Interests to the BRI Partnership, the transfer of ownership of the Transferor
Partnership to the BRI Partnership, to the assignment by the Borrower Corporate
General Partner of all of its interests in the Borrower Partnership to the
Borrower LLC General Partner, to the withdrawal from the Borrower Partnership of
the Borrower Corporate General Partner, and to the admission to the Borrower
Partnership of the Borrower LLC General Partner as a fifty percent (50%) general
partner. The BRI Partnership shall supply any and all documentation and
additional information required by Lender in order to promptly complete the
request for the consent of Lender to the transactions contemplated hereunder.
The Transferor Partnership shall request that Lender state in writing any terms
and requirements, including the amount of any Loan Assumption Fees, to be
imposed by Lender in connection with its consent to the transactions
contemplated hereby. It shall be a condition of Closing that prior to October
15, 1997, Lender shall have granted its consent to the transactions contemplated
hereunder on terms and requirements reasonably satisfactory to the BRI
Partnership, shall have issued the Lender Estoppel Letter and shall have agreed
to release the Transferor Partners from all liability under the Loan Documents.
In the event that any of the terms or requirements required by Lender for its
consent are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership have received in
writing the terms and requirements of Lender for its consent. In the event
either (a) the consent of Lender is not obtained prior to the Closing or (b) the
BRI Partnership does not approve the terms and conditions of Lender, and the BRI
Partnership gives timely notice of termination hereunder to the Transferor
Agent, this Agreement shall terminate without further action by any party, and,
thereafter this Agreement shall be void and without recourse to all parties,
except for provisions which are expressly stated to survive termination of this
Agreement. In the event the Lender shall not have agreed to release the
Transferor Partners from all liability under the Loan Documents or the Lender
shall have placed terms and conditions on the Transferor Partners that are
unacceptable to them, the Transferor Agent may terminate this Agreement by
written notice given to the BRI Partnership within fifteen (15) business days
after the Transferor Agent has received in writing notice that the Lender has
refused to release the Transferor Partners from liability under the Loan
Documents or has imposed such unacceptable terms and conditions. If the
Transferor Agent gives timely notice of termination to the BRI Partnership, this
Agreement shall terminate without further action by any party, and, thereafter
this 


                                      -63-
<PAGE>

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

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private placement of common stock or other equity
securities of BRI (the "Private Placement"). The Transferor Partners shall
supply any documentation and additional information required by BRI in order to
complete the offering materials in connection with the Public Offering or the
Private Placement. The obligation of the BRI Partnership to proceed with the
Closing of the transactions contemplated by this Agreement is expressly
conditioned upon the successful completion of the Public Offering and the
Private Placement raising a minimum of $75,000,000.00. If the Public Placement
and the Private Placement do not in the aggregate complete offerings which raise
a minimum of $75,000,000 as aforesaid prior to the Closing Date hereunder, the
BRI Partnership shall have the right to terminate this Agreement effective as of
the Closing Date, and, thereafter this Agreement 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 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.

sufficiency of which are hereby acknowledged, the Transferor Partners and the
BRI Partnership hereby covenant and agree as follows:


                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its
designees, shall execute and deliver an Amended and Restated Agreement of
Limited Partnership in the form of Exhibit IV attached hereto (the "Amended
Transferor Partnership Agreement") and an Amended and Restated Certificate of
Limited Partnership in the form of Exhibit V attached hereto (the "Amended
Transferor Partnership Certificate") pursuant to which the BRI Partnership, or
its designees, shall be admitted and the Transferor Partners shall withdraw, as
the partners of the Transferor Partnership and be released of all liability
thereunder, and the terms of the Transferor Partnership shall be amended in
accordance with the Amended Transferor Partnership Agreement.

     1.02 Property Title. On or before September 5, 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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the 

                                       -3-

<PAGE>


Transferor 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, a non-imputation 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 Partnership on or before September 5, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 Partners at Closing. The Transferor Partnership
shall be deemed to have refused to cure any unacceptable exceptions unless the
Transferor Partnership, within ten (10) days after receipt of notice from the
BRI Partnership, shall notify the BRI Partnership in writing that the Transferor
Partnership will attempt to cure such unacceptable exceptions. If the Transferor
Partnership 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 Partnership 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 Partnership
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.


                                       -4-

     1.03 Survey. On or before September 5, 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 Partnership promptly after its receipt 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 Partnership on or
before September 5, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 

                                       -6-

<PAGE>



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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income 

                                       -7-

<PAGE>


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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.


                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be $11,942,522, which shall consist of BRI Partnership Units, to
be issued by the BRI Partnership to the Transferor Partners 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) $11,942,522, 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, at its election, may pay in full the
outstanding principal balance of the Note dated October 26, 1987, in the
original principal amount of $9,600,000 (the "Note") evidencing the loan (the
"Loan") made to the Transferor Partnership by CRIIMI MAE Services Limited
Partnership ("Lender") and secured by the Loan Documents.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

                                       -8-

<PAGE>


     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or
liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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.


                                       -9-

     (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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Retention of Escrow. At the Closing, the Transferor Partnership shall
disburse the escrow deposits set forth on Schedule C as provided in Section
12.01.

any event not later than October 31, 1997 the ("Closing Date"). The "Time of

referred to in the Commitment in reliance on the execution by the Transferor
Agent pursuant to a Power of Attorney for all Transferor Partners 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 Partners. It is agreed that time is of the
essence of this Agreement.

     5.35 Investment Representations and Warranties. Each Transferor Partner for
itself, severally and not jointly, represents, warrants, acknowledges and agrees
as follows:

     (a) Such Transferor Partner 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) Such Transferor Partner understands that the BRI Partnership Units to
be issued to each Transferor Partner 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 such Transferor Partner.

     (c) Such Transferor Partner 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

Transferor Partner 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, such Transferor Partner 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.
Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such that it is able to bear all risks of the
investment in the BRI Partnership and BRI for an indefinite 

                                      -23-

<PAGE>



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 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. Such Transferor Partner 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) Such Transferor Partner is an "accredited investor" within the meaning
of Rule 501(a) promulgated under the Act.

     (e) Such Transferor Partner understands that an investment in the BRI
Partnership and BRI involves substantial risks. Such Transferor Partner
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) Such Transferor Partner 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:

Partnership shall cause the Transferor Partnership to 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

vested in the Transferor Partners until the Time of Closing.

or in excess of $750,000.00) 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 Partners at or prior to the Time 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 (b) proceed with the contribution and transfer
of the Transferor Partnership Interests, and in such case, unless the Transferor

in any event exceed $25,000.00, and the obligations of the Transferor
Partnership with respect to such violations shall cease.

and hold the BRI Partnership harmless against and with respect to (i) any loss
or damage (including reasonable attorney's fees) to the BRI Partnership
subsequent to the Closing Date, resulting from (A) any inaccuracy in or breach
of any representation or warranty of the Transferor Partnership set forth in
Section 5A or of such Transferor Partner set forth in Section 5B or (B)
resulting from any breach or default by the Transferor Partnership or such
Transferor Partner of any obligation of the Transferor Partnership or such
Transferor Partner under this Agreement or (ii) from liabilities for borrowed
money (other than the payments under the Loan due after the Closing) incurred by
the Transferor Partnership or the Property prior to the Closing; provided that
no Transferor Partner shall be required to indemnify the BRI Partnership for any
amounts in excess of 50% of the fair market value of the BRI Partnership Units
received by such Transferor Partner as of the date such indemnification
obligation is satisfied (except for indemnification obligations with respect to
representations of each of the Transferor Partners in Section 5.34, which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner) (collectively, the "Cap"); and provided further that to the extent any
of the Transferor Partners have any indemnification obligation to the BRI
Partnership, the Transferor Partners may elect to satisfy such indemnification
obligation by directing the BRI Partnership to cancel such amount of BRI
Partnership Units acquired by such Transferor Partner pursuant to this 

                                      -39-

<PAGE>



Agreement having a fair market value (measured at the time such BRI Partnership
Units are returned or cancelled) equal to the indemnification obligation of such
Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including
reasonable attorney's fees) to the Transferor Partners, subsequent to the
Closing Date, resulting from (A) any inaccuracy in or breach of any
representation or warranty of the BRI Partnership or (B) resulting from any
breach or default by the BRI Partnership of any obligation of the BRI
Partnership under this Agreement or (ii) from liabilities of the Transferor
Partnership or the Property after the Closing (except for such liabilities
resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor Partner under Section 10.05(b)(i) for any amounts in excess of 50% of

satisfied of the BRI Partnership Units received by such Transferor Partner
(except for indemnification obligations with respect to Sections 6.10 and 11.03
which shall be limited to 100% of the fair market value as of the date such
indemnification obligation is satisfied of the BRI Partnership Units received by
such Transferor Partner).

     (c) The indemnification obligations of the Transfer Partners and the BRI
Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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 any of the Transferor Partners 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 Partners for a breach of any of the terms,
conditions, 


                                      -40-

<PAGE>



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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section
708(b)(1)(B) of the Code and its tax year shall close on the Closing Date. The
Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be
filed by or on behalf of the Transferor Partnership with respect to all tax
years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,
which shall not be unreasonably withheld or delayed. The BRI Partnership shall
assist the Transferor Agent in obtaining such data and information regarding the
Transferor Agent to permit the Transferor Partnership to prepare such returns or
to respond to any audits or assessments for the periods covered by such returns.

connection with the issuance of the BRI Partnership Units to the Transferor
Partners as contemplated by this Agreement and as to such other matters as are

the BRI Partnership is required to deliver to the Transferor Partners pursuant
to any other provisions of this Agreement or which the Transferor Partners may,
either at or subsequent to the Closing, deem reasonably necessary in order to

receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are

to take such actions as may be necessary to effectuate the foregoing right
granted by the BRI Partnership to the Transferor Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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

                                      -43-

<PAGE>



condemnation proceeds in accordance with Section 1033 of the Code and hold the
same until the expiration of the No Transfer Period.

     (c) Intentionally Omitted.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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 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 omitted;

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer 

                                      -45-

<PAGE>



Allocation Schedule"), which shall be based upon the Preliminary Transfer
Allocation Schedule, shall incorporate all adjustments and prorations to be made
pursuant to Section 12 and shall set forth (i) the name of each Transferor
Partner, (ii) the number of Unrestricted Distribution BRI Partnership Units to
be received by each Transferor Partner, and (iii) the number of the Restricted
Distribution BRI Partnership Units to be received by each Transferor Partner.
The BRI Partnership shall have no obligation or liability with respect to the
preparation or accuracy of the Preliminary Transferor Allocation Schedule or the
Transfer Allocation Schedule or the distribution of the BRI Partnership Units or
the BRI Additional Payment, if applicable, to the Transferor Partners and the
Transferor Partners hereby release the BRI Partnership from any such obligation
or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, such amount shall be paid in the form of BRI

     13.03 Transferor Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the

Agreement. In addition to the foregoing, if the BRI Partnership desires to

     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
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 all
of the Transferor Partners desire to accept the transfer of the BRI Partnership

willfully refuses to perform the BRI Partnership's obligations hereunder, the
Transferor Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

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

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

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. Each Transferor Partner hereby
acknowledge and agrees that a portion of the amount due to such Transferor
Partner will be used to pay the fees and expenses attributable to the
transaction contemplated by this Agreement, which fees and expenses are the
several obligations of the Transferor Partners pursuant to the terms of this
Agreement. Each Transferor Partner and the Transferor Partnership 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 Partnership 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, each of the Transferor Partners 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 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. Each of the Transferor Partners acknowledges and agrees that
(i) any and all Direct Costs shall be allocated based on the pro rata number of
BRI Partnership Units allocated to each of them with respect to their interest
in the Transferor Partnership and (ii) any and all Indirect Costs shall be
allocated among the Transferor Partners and the Related Entities at Closing
based on the pro rata number of BRI Partnership Units allocated at Closing to
each of them. Each of the Transferor Partners 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.

     WHEREAS, the Transferor Partners desire to become limited partners of the

respective general and limited partnership interests in the Transferor
Partnership (collectively referred to as the "Transferor Partnership Interests")
to the BRI Partnership, and the BRI Partnership desires to admit the Transferor
Partners as limited partners in the BRI Partnership and to accept such
contribution from the Transferor Partners; and

     WHEREAS, in exchange for such contribution, the Transferor Partners desire
to receive BRI Partnership Units in accordance with the terms of this Agreement
and the BRI Partnership Agreement.

     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 Partners and the
BRI Partnership hereby covenant and agree as follows:

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its
designees, shall execute and deliver an Amended and Restated Agreement of
Limited Partnership in the form of Exhibit IV attached hereto (the 



                                      -3-
<PAGE>

"Amended Transferor Partnership Agreement") and an Amended and Restated
Certificate of Limited Partnership in the form of Exhibit V attached hereto (the
"Amended Transferor Partnership Certificate") pursuant to which the BRI
Partnership, or its designees, shall be admitted and the Transferor Partners
shall withdraw, as the partners of the Transferor Partnership and be released of
all liability thereunder, and the terms of the Transferor Partnership shall be
amended in accordance with the Amended Transferor Partnership Agreement.

     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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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, a non-imputation
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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan 


                                      -4-
<PAGE>

Documents and 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 Partners at Closing. The Transferor Partnership
shall be deemed to have refused to cure any unacceptable exceptions unless the
Transferor Partnership, within ten (10) days after receipt of notice from the
BRI Partnership, shall notify the BRI Partnership in writing that the Transferor
Partnership will attempt to cure such unacceptable exceptions. If the Transferor
Partnership 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 Partnership 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 Partnership
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

Transferor Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership of the unacceptable
survey matters as described above, the 


                                      -5-
<PAGE>

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 Partnership in writing of such fact as above
provided, the Transferor Partnership shall have thirty (30) days from the date
the Transferor Partnership receives notice of such unacceptable survey matters,
at the option of the Transferor Partnership, to cure such unacceptable survey
matters. The Transferor Partnership shall be deemed to have refused to cure any
unacceptable survey matters unless the Transferor Partnership, within ten (10)
days after receipt of notice from the BRI Partnership, shall notify the BRI
Partnership in writing that the Transferor Partnership will attempt to cure such
unacceptable survey matters. If the Transferor Partnership 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
Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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


                                      -6-
<PAGE>

rely upon the covenants, representations, warranties or agreements made by the
Transferor Partnership 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 Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners by reason
thereof including, without limitation, reasonable attorneys' fees and
disbursements; provided, however, that


                                      -7-
<PAGE>

nothing contained herein is intended to obligate the BRI Partnership to
indemnify, pay or otherwise reimburse the Transferor Partners 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 Partners 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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $6,844,284, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.


                                      -8-
<PAGE>

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of The Patrician
Financial Company ("Lender"), securing the outstanding principal balance of the
Note dated October 29, 1996, in the original principal amount of $5,976,000 (the
"Note") evidencing the loan (the "Loan") made to the Borrower Partnership by
Lender. The Loan is also secured by the other Loan Documents (as defined in
Section 5.20 hereof) which shall be an obligation of the Borrower Partnership
and the Transferor Partnership as of the Closing subject to any exculpation from
liability provisions therein. The Transferor Partnership shall also remain as
obligor of the outstanding principal balance of the note dated October 29, 1996
in the original principal amount of the Note (the "Borrower Partnership Note"),
evidencing the loan made to the Transferor Partnership by the Borrower
Partnership (the "Borrower Partnership Loan").

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner 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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership
owes any amounts to the Transferor Partners as a result of prorations and
apportionments (the "BRI Additional Payment"), 


                                      -9-
<PAGE>

at Closing, the BRI Partnership shall pay the BRI Additional Payment to the
Transferor Agent in accordance with the election made by each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or
liability with respect to the preparation or accuracy of the Preliminary
Transferor Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

referred to in the Commitment in reliance on the execution by the Transferor
Agent pursuant to a Power of Attorney for all Transferor Partners 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 Partners. It is agreed that time is of the
essence of this Agreement.

only security taken or held in connection with the Note is evidenced in the Loan
Documents. No security has been taken or held in connection with the Borrower
Partnership Note. The Loan Documents do not secure any other indebtedness but
the Loan or the Borrower Partnership Loan. To the best knowledge of the

any governmental entity or other person that the Property, or current or former
operations on the Property, are not or have not been in material compliance with
any Environmental Laws or that the Transferor Partnership has any material
liability with respect thereto. To the Transferor Partnership's knowledge,
except as set forth in the Environmental Reports or in the BRI Environmental
Reports, there are no underground tanks for Hazardous Materials, active or
abandoned, at the Property and no Hazardous Materials are present or have been
released in a reportable quantity, 


                                      -20-

where such a quantity has been established by statute, ordinance, rule,

limitation, obligations under the common law), ordinances, orders, rules and
regulations, as any of the foregoing may have been amended, supplemented or
supplanted prior to the Closing, relating to regulation or control of hazardous,
toxic or dangerous substances, materials or wastes (collectively, "Hazardous

Transferor Partnership's knowledge the Property and the current use thereof
comply in all material respects with (a) all applicable laws and (b) all
restrictive covenants and title encumbrances affecting the Property. The
Transferor Partnership holds all material licenses, permits and authorizations

for itself, severally and not jointly, represents, warrants, acknowledges and
agrees as follows:

     (a) Such Transferor Partner is acquiring the BRI Partnership Units for

the securities laws of any state ("Blue Sky Laws") by reason of a specific

satisfaction.

     (f) Such Transferor Partner acknowledges and agrees that:

     be registered under the Act in reliance upon the exemption afforded by

     applicable securities laws;

          (ii) any shares of common stock issued upon exchange of the BRI

     The Transferor Partnership represents, warrants and covenants to the BRI
Partnership as of the date hereof as follows:

has all 


                                      -26-
<PAGE>

requisite power to maintain the Loan from Lender and to maintain the Borrower
Partnership Loan to the Transferor Partnership and to carry on its business as
presently being conducted and as proposed to be conducted. The Borrower
Partnership is duly qualified to do business in all jurisdictions in which the
failure to be so qualified would have a Material Adverse Effect on the Borrower
Partnership's business.

     5.38 Compliance with Other Instruments, etc. The Borrower Partnership is
not in violation of any term contained in the Borrower Partnership Agreement, or
to the Transferor Partnership's knowledge in any other material instrument or
contract to which the Borrower Partnership is a party, and to the Transferor
Partnership's knowledge the Borrower Partnership is not in violation of any
order, statute, rule or regulation applicable to it, except for such violations
which would not have a Material Adverse Effect. Neither the execution, delivery
and performance of this Agreement by the Transferor Partnership, nor the
contribution of the Transferor Partnership Interests by the Transferor Partners
hereunder, nor the assignment and transfer of the Borrower General Partnership
Interest by the Borrower Corporate General Partner to the Borrower LLC General
Partner will result in any Material Adverse Effect or be in conflict with or
constitute a default under the Borrower Partnership Agreement or result in the
creation of any mortgage, pledge, lien, encumbrance or charge upon any of the
properties or assets of the Borrower Partnership.

     5.39 Partnership Capitalization. The Borrower Partnership Agreement (i) is
the only agreement among the partners thereto relating to the organization,
operation, or management of the Borrower Partnership, (ii) is in full force and
effect and (iii) has not been amended or modified. The Transferor Partnership

obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner) (collectively, the "Cap"); and provided further that to the extent any
of the Transferor Partners have any indemnification obligation to the BRI
Partnership, the Transferor Partners may elect to satisfy such indemnification
obligation by directing the BRI Partnership to cancel such amount of BRI

Partnership for which the BRI Partnership is indemnified under Section 10.05(a)

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 any of the Transferor Partners shall
have any liability for claims made under Section 10.05(a) or 10.05(b) unless and

the indemnifying party shall be liable for the portion of losses exceeding
$50,000).

exclusive remedy after the Closing Date for damages available to the BRI
Partnership or the Transferor Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

satisfaction of the Transferor Partners' distribution rights under Section 8.2

                                      -51-
<PAGE>

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
Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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


                                      -52-
<PAGE>

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

     12.01 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 the provisions of 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;


                                      -53-

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transferor Allocation Schedule (the "Transferor Allocation Schedule"), which
shall be based upon the Preliminary Transferor Allocation Schedule, shall
incorporate all adjustments and prorations to be made pursuant to Section 12,
and shall set forth (i) the name of each Transferor Partner, (ii) the number of
Unrestricted Distribution BRI Partnership Units to be received by each
Transferor Partner, and (iii) the number of Restricted Distribution BRI
Partnership Units to be received by each Transferor Partner. The BRI Partnership
shall have no obligation or liability with respect to the preparation or
accuracy of the Preliminary Transferor Allocation Schedule or the Transferor
Allocation Schedule or the distribution of the BRI Partnership Units or the BRI
Additional Payment, if applicable, to the Transferor Partners and the Transferor
Partners hereby release the BRI Partnership from any such obligation or
liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

required to remove all Monetary Liens.

     13.03 Transferor Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the

hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners the amount of all reasonable legal fees, court

or in equity of the BRI Partnership in the event of a default by the Transferor
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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

Transferor Agent shall be entitled to terminate this Agreement by written notice
given to the BRI Partnership within seven (7) days after the Closing Date and

hereunder except for provisions which are expressly stated to survive
termination of this Agreement. In addition to the foregoing, if all of the
Transferor Partners desire 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
Partners, jointly, but not severally, at their option, shall have the right to
compel specific performance by the BRI Partnership hereunder, in which event the

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
Partners and QPI in accordance with the provisions of Section 19 hereof. In no

commission to APC.

Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as

Agreement shall be void and without recourse to all parties hereunder except for

     17.03 Financing Assumption Condition. The BRI Partnership and the
Transferor Partnership shall use reasonable efforts to obtain the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI

to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership, the transfer of
ownership of the 


                                      -62-
<PAGE>

Transferor Partnership to the BRI Partnership, to the assignment by the Borrower
Corporate General Partner of all of its interests in the Borrower Partnership to
the Borrower LLC General Partner, to the withdrawal from the Borrower
Partnership of the Borrower Corporate General Partner, and to the admission to
the Borrower Partnership of the Borrower LLC General Partner as a fifty percent
(50%) general partner. The BRI Partnership shall supply any and all
documentation and additional information required by Lender in order to promptly
complete the request for the consent of Lender to the transactions contemplated
hereunder. The Transferor Partnership shall request that Lender state in writing
any terms and requirements, including the amount of any Loan Assumption Fees, to
be imposed by Lender in connection with its consent to the transactions
contemplated hereby. It shall be a condition of Closing that prior to October
15, 1997, Lender shall have granted its consent to the transactions contemplated
hereunder on terms and requirements reasonably satisfactory to the BRI
Partnership, shall have issued the Lender Estoppel Letter and shall have agreed
to release the Transferor Partners from all liability under the Loan Documents.
In the event that any of the terms or requirements required by Lender for its
consent are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership have received in
writing the terms and requirements of Lender for its consent. In the event
either (a) the consent of Lender is not obtained prior to the Closing or (b) the
BRI Partnership does not approve the terms and conditions of Lender, including
the amount of any Loan Assumption Fees in excess of 1% of the unpaid principal
balance, and the BRI Partnership gives timely notice of termination hereunder to
the Transferor Agent, this Agreement shall terminate without further action by
any party, and, thereafter this Agreement shall be void and without recourse to
all parties, except for provisions which are expressly stated to survive
termination of this Agreement. In the event the Lender shall not have agreed to
release the Transferor Partners from all liability under the Loan Documents or
the Lender shall have placed terms and conditions on the Transferor Partners
that are unacceptable to them, the Transferor Agent may terminate this Agreement
by written notice given to the BRI Partnership within fifteen (15) business days
after the Transferor Agent has received in writing notice that the Lender has
refused to release the Transferor Partners from liability under the Loan
Documents or has imposed such unacceptable terms and conditions. If the
Transferor Agent gives timely notice of termination to the BRI Partnership, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private


                                      -63-
<PAGE>

placement of common stock or other equity securities of BRI (the "Private
Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     NOW, THEREFORE, in consideration of the mutual undertakings and covenants

sufficiency of which are hereby acknowledged, the Transferor Partners and the
BRI Partnership hereby covenant and agree as follows:

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its
designees, shall execute and deliver an Amended and Restated Agreement of
Partnership in the form of Exhibit IV attached hereto (the "Amended Transferor
Partnership Agreement") pursuant to which the BRI Partnership, or its designees,
shall be admitted and the Transferor Partners shall withdraw, as the partners of
the Transferor Partnership and be released of all liability thereunder, and the
terms of the Transferor Partnership shall be amended in accordance with the
Amended Transferor Partnership Agreement.

     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 



                                       -3-

<PAGE>



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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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, a non-imputation
endorsement, a fairways 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of 


                                       -4-

<PAGE>



(A) ten (10) days after the Transferor Partnership 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 Partnership
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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to



                                       -5-

<PAGE>



cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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



                                       -6-

<PAGE>



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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 


                                       -7-

<PAGE>



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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $7,068,723, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of The Patrician
Financial Company ("Lender"), securing the outstanding principal balance of the
Note dated October 29, 1996, in the original principal amount of $6,043,000 (the
"Note") evidencing the loan (the "Loan") made to the Borrower Partnership by
Lender. The Loan is also secured by the other Loan Documents (as defined in
Section 5.20 hereof) which shall be an obligation of the Borrower Partnership
and the Transferor Partnership as of the Closing subject to any exculpation from

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each

Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner 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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership

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 each Transferor Partner pursuant to Section 12.04. The
Transferor Agent shall be liable to distribute the BRI Partnership Units and if
applicable, a pro-rata share of the BRI Additional Payment to each of the

BRI Partnership shall have no obligation or liability with respect to the

or the BRI Additional Payment, if applicable, to the Transferor Partners and the
Transferor Partners hereby release the BRI Partnership from any such obligation

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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.

representations of each of the



                                      -46-

<PAGE>



Transferor Partners in Section 5.34, which shall be limited to 100% of the fair
market value as of the date such indemnification obligation is satisfied of the
BRI Partnership Units received by such Transferor Partner) (collectively, the
"Cap"); and provided further that to the extent any of the Transferor Partners
have any indemnification obligation to the BRI Partnership, the Transferor
Partners may elect to satisfy such indemnification obligation by directing the
BRI Partnership to cancel such amount of BRI Partnership Units acquired by such
Transferor Partner pursuant to this Agreement having a fair market value
(measured at the time such BRI Partnership Units are returned or cancelled)
equal to the indemnification obligation of such Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including

Partnership, respectively, with respect to any representation or warranty, shall

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 any of the Transferor Partners shall
have any liability for claims made under Section 10.05(a) or 10.05(b) unless and
until the 


                                      -47-

<PAGE>



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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

Partnership shall terminate for federal income tax purposes pursuant to Section

(iv) UCC search costs.

     11.03 Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Partners, in their
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Partnership has not dissolved, terminated or liquidated, the right to
receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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 


                                      -51-

<PAGE>



to allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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 the provisions of 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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 


                                      -53-

<PAGE>



prorations to be made pursuant to this Section 12. Transferor Agent and the BRI
Partnership shall cooperate in the furnishing of all information and
documentation necessary to prepare such calculations. Prior to Closing, the
Transferor Agent shall deliver to the BRI Partnership the final Transferor
Allocation Schedule (the "Transferor Allocation Schedule"), which shall be based
upon the Preliminary Transferor Allocation Schedule, shall incorporate all
adjustments and prorations to be made pursuant to Section 12, and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transferor Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership shall assign and
deliver to the BRI Partnership all of the tenant security deposits, including
interest accrued 

                                      -54-

<PAGE>



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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, such amount shall be paid in the form of 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
Partnership shall have elected to settle adjustments under Section 12.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor

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 Transferor
Partnership Interests in accordance with the terms of this Agreement and the
Transferor Partners willfully refuse to perform the Transferor Partners'
obligations hereunder, the BRI Partnership, at its option, shall have the right
to compel specific performance by the Transferor Partners hereunder, in which
event the BRI Partnership shall have the right to recover from the Transferor
Partners 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 Partners in lieu
of all other rights and remedies which the BRI Partnership may have against the
Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

similar agent who might have a claim or right to claim a commission or fee in
connection with this transaction. The Transferor Partnership 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 Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

after the Transferor Agent has received in writing notice that the Lender has

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as

complete the offering materials in connection with the Public Offering or the
Private Placement. The obligation of the BRI Partnership to proceed with the
Closing of the transactions contemplated by this Agreement is expressly
conditioned upon the successful completion of the Public Offering and the
Private Placement raising a minimum of $75,000,000.00. If the Public Placement
and the Private Placement do not in the aggregate complete offerings which raise
a minimum of $75,000,000 as aforesaid prior to the Closing Date hereunder, the
BRI Partnership shall have the right to terminate this Agreement effective as of
the Closing Date, and, thereafter this Agreement shall be void and without

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 agreements are more
particularly described on Schedule K attached hereto (collectively the "Related

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.

     19.01 Transferor Allocation Schedule. Each Transferor Partner acknowledges
and agrees that the Transferor Allocation Schedule attached hereto as Exhibit I

purpose of performing the administrative activities to be performed under this

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

     19.03 Allocation of Transaction Costs. Each Transferor Partner hereby
acknowledge and agrees that a portion of the amount due to such Transferor
Partner will be used to pay the fees and expenses attributable to the
transaction contemplated by this Agreement, which fees and expenses are the
several obligations of the Transferor Partners pursuant to the terms of this
Agreement. Each Transferor Partner and the Transferor Partnership 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 Partnership due to said fees solely benefiting it 


                                      -66-

<PAGE>



("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, each of the Transferor Partners hereby agrees
that: (i) QPI shall be entitled to an aggregate administrative fee of $200,000

Partnerships and related entities (collectively, the "Related Entities"), which
shall be 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. Each of the Transferor Partners acknowledges and agrees that
(i) any and all Direct Costs shall be allocated based on the pro rata number of
BRI Partnership Units allocated to each of them with respect to their interest
in the Transferor Partnership and (ii) any and all Indirect Costs shall be
allocated among the Transferor Partners and the Related Entities at Closing
based on the pro rata number of BRI Partnership Units allocated at Closing to
each of them. Each of the Transferor Partners 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.

intending to be legally bound hereby, each of the undersigned Transferor
Partners and the Borrower Corporate General Partner hereby irrevocably

have a 3.1 zoning endorsement, a comprehensive endorsement, a non-imputation
endorsement, a fairways 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of 



                                      -4-
<PAGE>


(A) ten (10) days after the Transferor Partnership 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 Partnership
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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to




                                      -5-
<PAGE>


cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 



                                      -6-
<PAGE>


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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 



                                      -7-
<PAGE>


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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $8,097,227, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing and, minus (Z) the amount required to pay the various outstanding
loans owed by the Transferor Partnership to the Transferor Partners or their
affiliates or to other third-party lenders (the "Other Loans"), but in any
event, the total amount to be deducted under this clause (Z) shall not exceed an
amount equal to the difference between the Consideration Amount minus the
outstanding principal balance of the Note (the "Other Loans BRI Cap").

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of CPC Mortgage
Capital, LLC, as successor to Maryland National Mortgage Corporation ("Lender"),
securing the outstanding principal balance of the Note dated October 19, 1989,
in the original


                                      -8-
<PAGE>


principal amount of $8,000,000 (the "Note") evidencing the loan (the "Loan")
made to the Borrower Partnership by Lender. The Loan is also secured by the
other Loan Documents (as defined in Section 5.20 hereof) which shall be an
obligation of the Borrower Partnership and the Transferor Partnership as of the
Closing subject to any exculpation from liability provisions therein. The
Transferor Partnership shall also remain as obligor of the outstanding principal
balance of the note dated October 19, 1989 in the original principal amount of
the Note (the "Borrower Partnership Note"), evidencing the loan made to the
Transferor Partnership by the Borrower Partnership (the "Borrower Partnership
Loan").

     At the Closing, the BRI Partnership shall pay the amount required to
satisfy the Other Loans, provided that the amount to be paid by the BRI
Partnership shall not exceed the Other Loans BRI Cap. If the amount paid by the
BRI Partnership is not sufficient to pay the Other Loans in full, the Transferor
Partnership shall pay, from funds otherwise allocable under this Agreement to
the Transferor Partners, all additional amounts required to pay off the Other
Loans in full. At least fifteen (15) days prior to the Closing, the Transferor
Agent shall deliver a pay-off letter from each holder of an Other Loan stating
the amount required to pay-off such Other Loan in full, and at Closing, the
Transferor shall deliver the original note evidencing each such Other Loan
marked "Paid in Full," or in the event that the original of any such note is not
available, such other evidence of the satisfaction of such note and release of
liability under such Other Loan as the BRI Partnership may require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor 




                                      -9-
<PAGE>


questionnaire in the form attached hereto as Exhibit 5 (the "BRI Questionnaire")
for each Transferor Partner. In the event that any Transferor Partner 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 all of the BRI Partnership Confirmations evidencing the
issuance of the BRI Partnership Units to the Transferor Partners in accordance
with the Transferor Allocation Schedule. In addition, if pursuant to Section 12,
the BRI Partnership owes any amounts to the Transferor Partners 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 each Transferor Partner pursuant to Section
12.04. The Transferor Agent shall be liable to distribute the BRI Partnership
Units and if applicable, a pro-rata share of the BRI Additional Payment to each
of the Transferor Partners in accordance with the Transferor Allocation
Schedule. The BRI Partnership shall have no obligation or liability with respect
to the preparation or accuracy of the Preliminary Transferor Allocation Schedule
or the Transferor Allocation Schedule or the distribution of the BRI Partnership
Units or the BRI Additional Payment, if applicable, to the Transferor Partners
and the Transferor Partners hereby release the BRI Partnership from any such
obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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 



                                      -10-
<PAGE>


terms and conditions as are specified in the BRI Partnership Agreement. Each
Transferor Partner 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
Partners 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
Partners a certified copy of the Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

                                    SECTION 3

                                   THE CLOSING

     3.01 Closing. Except as otherwise provided in this Agreement, the delivery

Partners, nor the contribution of the Transferor Partnership Interests by the
Transferor Partners hereunder, will result in any Material Adverse Effect or be
in conflict with or constitute a default under the Transferor Partnership
Agreement or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Transferor Partnership,
except for Permitted Exceptions.

     5.03 Governmental Consent, etc. Except for the requirement for the receipt
of the Lender approval in accordance with the provisions of Section 17.03, no

been amended or modified. Exhibit I sets forth an accurate and complete list of

     5.35 Investment Representations and Warranties. Each Transferor Partner for
itself, severally and not jointly, represents, warrants, acknowledges and agrees
as follows:

     (a) Such Transferor Partner 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) Such Transferor Partner understands that the BRI Partnership Units to
be issued to each Transferor Partner 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 such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons
set forth in Sections 5.35(a) and (b) above, the BRI Partnership Units (or

Partner 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

(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,
such Transferor Partner 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. Such Transferor Partner
acknowledges, represents and agrees that (i) its economic circumstances are such

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 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. Such Transferor Partner 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) Such Transferor Partner is an "accredited investor" within the meaning
of Rule 501(a) promulgated under the Act.

     (e) Such Transferor Partner understands that an investment in the BRI

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 



                                      -25-
<PAGE>


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) Such Transferor Partner 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

received by such Transferor Partner as of the date such indemnification
obligation is satisfied (except for indemnification obligations with respect to
representations of each of the Transferor Partners in Section 5.34, which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner) (collectively, the "Cap"); and provided further that to the extent any

having a fair market value (measured at the time such BRI Partnership Units are
returned or cancelled) equal to the indemnification obligation of such
Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including

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

Partnership, respectively, with respect to any representation or warranty, shall

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.

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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section
708(b)(1)(B) of the Code and its tax year shall close on the Closing Date. The
Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be
filed by or on behalf of the Transferor Partnership with respect to all tax
years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,

     11.03 Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Partners, in their
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Partnership has not dissolved, terminated or liquidated, the right to
receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments, or except as contemplated in Section
11.04 hereof, or as otherwise required by the holder of the Loan under the Loan
Documents, or change the 



                                      -52-
<PAGE>


terms in a manner that would change the Loan from nonrecourse to recourse within
the meaning of Section 752 of the Code and the regulations promulgated
thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     11.04 Post-Closing Refinancing. Notwithstanding the provisions of Section
11.03(c) hereof, the BRI Partnership and BRI shall cause the Transferor
Partnership within 90 days after the Closing Date to refinance the Loan with a
new non-recourse loan (the "New Loan") for an amount not less than $5,630,000
for a term not less than 



                                      -53-
<PAGE>


seven years, for an interest rate not to exceed that available under the Tier 2
FNMA Underwriting Guidelines and upon such other terms and conditions as may be
satisfactory to the BRI Partnership and BRI. The Transferor Partners shall pay
all costs and expenses incurred by the Transferor Partnership, the BRI
Partnership or BRI in connection with such refinancing, including, without
limitation, loan origination fees, lender legal fees and all other expenses
charged by the refinancing lender and the Transferor Partnership's, the BRI
Partnership's or BRI's attorneys' fees and costs (collectively, "Refinancing
Costs"), but excluding any escrow required to be established with the
refinancing lender and the cost of any repairs or replacements required by the
refinancing lender. At Closing, the Transferor Partners shall deposit in escrow
a sum (the "Refinancing Escrow Amount") equal to the lesser of (a) two (2%)
percent of the principal amount of the New Loan as estimated by the BRI
Partnership at the time of Closing (but in any event not more than $112,700), or
(b) an amount mutually agreed to by the Transferor Agent and the BRI
Partnership, with a mutually acceptable escrow agent and pursuant to a mutually
acceptable escrow agreement. The Refinancing Escrow Amount shall be used to pay
for the Refinancing Costs. The amount to be deposited by each Transferor Partner
shall be proportionate to the number of BRI Partnership Units to be received by
each Transferor Partner at Closing in accordance with the Transferor Allocation
Schedule. In the event that the actual Refinancing Costs are less than the
Refinancing Escrow Amount, the difference shall be refunded to the Transferor
Agent who shall distribute such refund to the Transferor Partners in proportion
to their respective contributions to the Refinancing Escrow Amount. Once the
Loan is refinanced under this Section, the provisions of Section 11.03(c) shall
apply to the New Loan as fully and completely as if all references in Section
11.03(c) to the Loan instead referred to the New Loan and all references to the
Loan shall be deemed to refer to the New Loan.

                                   SECTION 12

                 APPORTIONMENTS AND ADJUSTMENTS TO CONSIDERATION

     12.01 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 the provisions of 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 if there is a water meter on the Property, apportionment on the
Closing Date shall be



                                      -54-
<PAGE>


based on the last available reading, subject to adjustment after the Closing on
a per diem basis, when the next reading is available;

     (c) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transferor Allocation Schedule (the "Transferor Allocation Schedule"), which
shall be based upon the Preliminary Transferor Allocation Schedule, shall
incorporate all adjustments and prorations to be made pursuant to Section 12,
and shall set forth (i) the name of each Transferor Partner, (ii) the number of
Unrestricted Distribution BRI Partnership Units to be received by each
Transferor Partner, and (iii) the number of Restricted Distribution BRI
Partnership Units to be received by each Transferor Partner. The BRI Partnership
shall have no obligation or liability with respect to the preparation or
accuracy of the Preliminary Transferor Allocation Schedule or the Transferor
Allocation Schedule or the distribution of the BRI Partnership Units or the BRI
Additional Payment, if applicable, to the Transferor 



                                      -55-
<PAGE>


Partners and the Transferor Partners hereby release the BRI Partnership from any
such obligation or liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01 and the escrow required to be
established under Section 11.04, the Transferor Partners owe an amount to the
BRI Partnership or into escrow, the Transferor Partnership shall have the right
to elect on behalf of the Transferor Partners to adjust for such amounts owing
by the Transferor Partners to the BRI Partnership or the escrow 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 Partners, such amount shall be 


                                      -56-
<PAGE>


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
Partners 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 Partnership shall have elected to settle adjustments under
Section 12.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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 Transferor Partnership Interests in accordance with the terms of
this Agreement and the Transferor Partners willfully refuse to perform the
Transferor Partners' obligations hereunder, the BRI Partnership, at its option,
shall have the right to compel specific performance by the Transferor Partners
hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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 


                                      -57-
<PAGE>


exclusive remedies at law or in equity of the BRI Partnership in the event of a
default by the Transferor Partners in lieu of all other rights and remedies
which the BRI Partnership may have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as

                                    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-
<PAGE>

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-
<PAGE>

            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-
<PAGE>

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

     (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

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.

                               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.

     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.

                                     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.

     5.22   Permits and Compliance with Laws. The Transferor Corporation has not
            received written notice, and the Transferor Corporation has no
            actual knowledge, that (i) any approvals, consents, permits,

            and operated except, in the case of clauses (i), (ii), (iii) and
            (iv) as would not have a Material Adverse Effect. To the

            applicable laws and (b) all restrictive covenants and title
            encumbrances affecting the Property. The Transferor Corporation
            holds all material licenses, permits and authorizations required
            for the lawful use, operation and occupancy of the Property. The
            parties agree that all matters relating to compliance with

     5.25   Pre-Closing Deliveries Accurate. All of the materials delivered by
            the Transferor Corporation to the BRI Partnership pursuant to

            such proceedings, against or by the Transferor Corporation, 
            anticipated or contemplated by the Transferor Corporation.

     5.27   Liens. To the Transferor Corporation's knowledge, and subject to
            such matters as may be disclosed by the Commitment, the Property
            currently is free from mechanics' and materialmen's liens or other
            liens other than the Permitted Exceptions.

     5.28   Essential Facilities. Except as set forth in Schedule 5.28, the
            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

            furnishing to the Property of any essential building systems or
            utilities. Except as set forth on Schedule 5.28, no property not

            there are no presently planned public improvements which would
            result in the creation of a special improvement or similar lien upon
            the Property.

                                      -19-
<PAGE>

     (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-
<PAGE>

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-
<PAGE>

               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

indefinitely.

            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.

     (d) The BRI Partnership has previously delivered to the Transferor
Corporation a true and complete copy of the BRI Partnership's Federal Income Tax
Return for 1996, as filed with the Internal Revenue Service.

     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-
<PAGE>

            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-
<PAGE>

            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-
<PAGE>

            termination; or (b) proceed with the contribution and transfer of
            the Property, and in such case, unless the Transferor Corporation
            shall have previously restored the Property to its condition
            prior to the occurrence of any such damage or destruction, the
            Transferor Corporation shall pay over or assign to the BRI
            Partnership, on behalf of the Transferor Corporation, all amounts
            received or due (plus an amount equal to any deductible under any
            insurance policy covering the Property) from, and all claims
            against, any insurance company or governmental entity as a result
            of such destruction or taking and there shall be no adjustment to
            the Consideration hereunder. If prior to the Time of Closing, any
            such damage or destruction shall occur having a replacement cost
            of less than $100,000.00 or if any eminent domain notice or
            proceeding is commenced which does not affect any material
            portion of the Property, the BRI Partnership shall proceed to
            accept the contribution and transfer of the Property in
            accordance with the provisions of clause (b) above.


                                    SECTION 8

                                VIOLATIONS OF LAW

     8.01   Responsibility for Violations. All notices of material violations of
            laws, ordinances, regulations or insurance requirements ("Violations
            of Law"), which are issued or sent prior to the Closing Date by any
            governmental department, agency or bureau having jurisdiction as to
            conditions affecting the Property shall, to the extent reasonably
            practical be removed or complied with by the Transferor Corporation,
            at the expense of the Transferor Corporation, but in any event not
            to exceed $25,000.00, prior to the Closing Date; provided, however,
            that if Transferor Corporation is unable or unwilling, if the cost
            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
            with the transaction contemplated hereby in which event there shall
            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.

            consistent with past practice, the Transferor Corporation shall not,
            without the BRI Partnership's prior written consent (a) enter into
            any new lease for an apartment unit with a first-time tenant unless
            the lease is for a period of no more than one year and the rent
            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
            any Lease for an apartment unit with an existing tenant unless the
            lease is for a period of not more than one year and that the rent
            for the amended, renewal or extension term shall not be less than
            the amount of rent noted on the Rent Roll, for the respective
            apartment; or (d) terminate any Lease except in the ordinary course
            of business or by reason of a default by the tenant thereunder or by
            reason of the provisions contained in the Lease or as required by
            applicable law.

     9.02   Condition of Units. Up to the Time of Closing, all apartment units
            on the Property which become vacant shall be maintained in
            accordance with the Transferor Corporation's usual and customary
            practice without regard to the Closing contemplated by this
            Agreement. Except as otherwise specifically provided herein, the BRI
            Partnership acknowledges and agrees that all properties with units
            will be delivered in "as is" condition.

     9.03   Continuation of Service Contracts. The Transferor Corporation shall
            not modify or amend any Service Contract or enter into any new
            service contract for the Property, without the prior written consent
            of the BRI Partnership which consent shall not be unreasonably
            withheld or delayed, provided no consent shall be required with
            respect to any of the foregoing so long as such service contract is
            terminable without penalty by the then owner of the Property upon
            not more than thirty (30) days' notice.

     9.04   Replacement of Personal Property. No personal property included as
            part of the Property shall be removed from the Property unless the

            Schedule 9.05 attached hereto, the Transferor Corporation shall not
            withdraw, settle or otherwise compromise any protest or reduction
            proceeding affecting real estate taxes assessed against the Property
            for any fiscal period in which the Closing Date is to occur or any
            subsequent fiscal period without the prior written consent of BRI
            Partnership. Real estate tax refunds and credits received after the
            Closing Date which are attributable to (i) the fiscal tax year
            during which the Closing occurs shall be apportioned between the
            Transferor Corporation and the BRI Partnership, based upon the
            relative time periods before and after the Closing, or (ii) any
            fiscal year prior to the fiscal year in which the Closing occurs
            shall be paid to the Transferor Corporation, in either case after
            deducting the expenses of collection thereof, which obligation shall
            survive the Closing.

            the material terms and provisions of the Loan Documents up to the
            Closing, and (c) not alter or amend the Loan Documents, or seek or

            the Property in substantially its present condition, subject to the
            provisions of Section 7 hereof, and the Transferor Corporation shall
            operate and manage the Property in the same manner as it has
            operated the Property prior to the date hereof.

     9.08   Intentionally Deleted.

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
amount of BRI Partnership Units acquired by the Transferor Corporation pursuant
to this Agreement having a fair market value (measured at the time such BRI
Partnership Units are returned or cancelled) equal to the indemnification
obligation of the Transferor Corporation.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to

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

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

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-
<PAGE>

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

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

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.

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-
<PAGE>

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-
<PAGE>

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-
<PAGE>

            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-
<PAGE>

            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

<PAGE>

            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.

            common stock or other equity securities of BRI (the "Public
            Offering"), or (ii) a private placement of common stock or other

            Corporation shall supply any documentation and additional

            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

            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.

            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

            Agreement.

            hereof may be waived, modified, amended, discharged or terminated
            except by an instrument signed by the party against whom the
            enforcement of such waiver, modification, amendment, discharge or

            receive BRI Partnership Units.

     18.06  Drafts. This Agreement shall not be binding or effective until

                                   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-
<PAGE>

            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,

            affiliated persons or entities thereto, and (iv) agrees, subject
            to the provisions of Section 10.05, to indemnify and hold

            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

            willful malfeasance on the part of the Transferor Agent and/or

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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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, a non-imputation
endorsement, a fairways 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of 


                                      -4-
<PAGE>

(A) ten (10) days after the Transferor Partnership 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 Partnership
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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to


                                      -5-
<PAGE>

cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 


                                      -6-
<PAGE>

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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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


                                      -7-
<PAGE>

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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $9,615,177, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of The Patrician
Financial Company ("Lender"), securing the outstanding principal balance of the
Note dated October 29, 1996, in the original principal amount of $8,000,000 (the
"Note") evidencing the loan (the "Loan") made to the Borrower Partnership by
Lender. The Loan is also secured by the other Loan Documents (as defined in
Section 5.20 hereof) which shall be an obligation of the Borrower Partnership
and the Transferor Partnership as of the Closing subject to any exculpation from
liability provisions therein. The Transferor Partnership shall also remain as
obligor of the outstanding principal balance of the note dated October 29,


                                      -8-
<PAGE>

1996 in the original principal amount of the Note (the "Borrower Partnership
Note"), evidencing the loan made to the Transferor Partnership by the Borrower
Partnership (the "Borrower Partnership Loan").

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner 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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership
owes any amounts to the Transferor Partners 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 each Transferor Partner pursuant to Section 12.04. The
Transferor Agent shall be liable to distribute the BRI Partnership Units and if
applicable, a pro-rata share of the BRI Additional Payment to each of the
Transferor Partners in accordance with the Transferor Allocation Schedule. The
BRI Partnership shall have no obligation or liability with respect to the
preparation or accuracy of the Preliminary Transferor Allocation Schedule or the
Transferor Allocation Schedule or the distribution of the BRI Partnership Units
or the BRI Additional Payment, if applicable, to the Transferor Partners and the
Transferor Partners hereby release the BRI Partnership from any such obligation
or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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.

replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

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 all Transferor Partners 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 Partners. It is agreed that time is of the
essence of this Agreement.

Transferor Partnership is not in violation of any order, statute, rule or
regulation applicable to it, except for such violations which would not have a
Material Adverse Effect. Neither the execution, delivery and performance of this
Agreement by the Transferor Partners, nor the contribution of the Transferor
Partnership Interests by the Transferor Partners hereunder, will result in any
Material Adverse Effect or be in conflict with or constitute a default under the
Transferor Partnership Agreement or result in the creation of any mortgage,
pledge, lien, encumbrance or charge upon any of the properties or assets of the
Transferor Partnership, except for Permitted Exceptions.

     5.03 Governmental Consent, etc. Except for the requirement for the receipt

Rights Agreement.

     (b) Such Transferor Partner understands that the BRI Partnership Units to

<PAGE>

accuracy and completeness of the representations and warranties of such
Transferor Partner.

applicable Blue Sky Laws, or (iii) upon the BRI Partnership or BRI, as the case

(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

covered by this Agreement and has not relied upon the BRI Partnership or the
Transferor Agent, its 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.

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) Such Transferor Partner 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

               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

               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

                                      -46-

equal to the indemnification obligation of such Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor

representation or warranty of the BRI Partnership or (B) resulting from any
breach or default by the BRI Partnership of any obligation of the BRI
Partnership under this Agreement or (ii) from liabilities of the Transferor
Partnership or the Property after the Closing (except for such liabilities

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 any of the Transferor Partners shall
have any liability for claims made under Section 10.05(a) or 10.05(b) unless and

<PAGE>

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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

Partnership shall terminate for federal income tax purposes pursuant to Section

Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared

     11.03 Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Partners, in their
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Partnership has not dissolved, terminated or liquidated, the right to
receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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 


                                      -51-
<PAGE>

to allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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 the provisions of 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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


                                      -53-
<PAGE>

prorations to be made pursuant to this Section 12. Transferor Agent and the BRI
Partnership shall cooperate in the furnishing of all information and
documentation necessary to prepare such calculations. Prior to Closing, the
Transferor Agent shall deliver to the BRI Partnership the final Transferor
Allocation Schedule (the "Transferor Allocation Schedule"), which shall be based
upon the Preliminary Transferor Allocation Schedule, shall incorporate all
adjustments and prorations to be made pursuant to Section 12, and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transferor Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership shall assign and
deliver to the BRI Partnership all of the tenant security deposits, including
interest accrued 


                                      -54-
<PAGE>

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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners shall be in
default under this Agreement and the BRI Partnership shall be entitled to
terminate this Agreement by written notice


                                      -55-
<PAGE>

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 Transferor
Partnership Interests in accordance with the terms of this Agreement and the
Transferor Partners willfully refuse to perform the Transferor Partners'
obligations hereunder, the BRI Partnership, at its option, shall have the right
to compel specific performance by the Transferor Partners hereunder, in which
event the BRI Partnership shall have the right to recover from the Transferor
Partners 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 Partners in lieu
of all other rights and remedies which the BRI Partnership may have against the
Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

finder or


                                      -56-
<PAGE>

similar agent who might have a claim or right to claim a commission or fee in
connection with this transaction. The Transferor Partnership 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 Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

its interests in the Borrower Partnership to the Borrower LLC General Partner,
to the withdrawal from the Borrower Partnership of the Borrower Corporate
General Partner, and to the admission to the Borrower Partnership of the
Borrower LLC General Partner as a fifty percent (50%) general partner, and to
obtain the Lender Estoppel Letter. The Transferor Partnership, with the BRI
Partnership's cooperation, shall immediately commence to obtain the consent of
Lender necessary to permit the contribution of the Transferor Partnership
Interests to the BRI Partnership, the transfer of ownership of the Transferor
Partnership to the BRI Partnership, to the assignment by the Borrower Corporate

Partnership of the Borrower LLC General Partner as a fifty percent (50%) general

additional information required by Lender in order to promptly complete the
request for the consent of Lender to the transactions contemplated hereunder.
The Transferor Partnership shall request that Lender state in writing any terms
and requirements, including the amount of any Loan Assumption Fees, to be
imposed by Lender in connection with its consent to the transactions
contemplated hereby. It shall be a condition of Closing that prior to October
15, 1997, Lender shall have granted its consent to the transactions contemplated
hereunder on terms and requirements reasonably satisfactory to the BRI
Partnership, shall have issued the Lender Estoppel Letter and shall have agreed
to release the Transferor Partners from all liability under the Loan Documents.
In the event that any of the terms or requirements required by Lender for its
consent are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership have received in
writing the terms and requirements of Lender for its consent. In the event
either (a) the consent of Lender is not obtained prior to the Closing or (b) the
BRI Partnership does not approve the terms and conditions of Lender, including
the amount of any Loan Assumption Fees in excess of 1% of the unpaid principal
balance, and the BRI Partnership gives timely notice of termination hereunder to
the Transferor Agent, this Agreement shall terminate without further action by
any party, and, thereafter this Agreement shall be void and without recourse to
all parties, except for provisions which are expressly stated to survive
termination of this Agreement. In the event the Lender shall not have agreed to
release the Transferor Partners from all liability under the Loan Documents or
the Lender shall have placed terms and conditions on the Transferor Partners
that are unacceptable to them, the Transferor Agent may terminate this Agreement
by written notice given to the BRI Partnership within fifteen (15) business days
after the Transferor Agent has received in writing notice that the Lender has
refused to release the Transferor Partners from liability under the Loan
Documents or has imposed such unacceptable terms and conditions. If the
Transferor Agent gives timely notice of termination to the BRI Partnership, this
Agreement shall terminate without further action by any party, and, 


                                      -62-
<PAGE>

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

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private placement of common stock or other equity
securities of BRI (the "Private Placement"). The Transferor Partners shall
supply any documentation and additional information required by BRI in order to
complete the offering materials in connection with the Public Offering or the
Private Placement. The obligation of the BRI Partnership to proceed with the
Closing of the transactions contemplated by this Agreement is expressly
conditioned upon the successful completion of the Public Offering and the
Private Placement raising a minimum of $75,000,000.00. If the Public Placement
and the Private Placement do not in the aggregate complete offerings which raise
a minimum of $75,000,000 as aforesaid prior to the Closing Date hereunder, the
BRI Partnership shall have the right to terminate this Agreement effective as of
the Closing Date, and, thereafter this Agreement 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 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.

<PAGE>

     WHEREAS, in exchange for such contribution, the Transferor Partners desire
to receive BRI Partnership Units in accordance with the terms of this Agreement
and the BRI Partnership Agreement.

     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 Partners and the
BRI Partnership hereby covenant and agree as follows:


                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its
designees, shall execute and deliver an Amended and Restated Agreement of
Limited Partnership in the form of Exhibit IV attached hereto (the "Amended
Transferor Partnership Agreement") and an Amended and Restated Certificate of
Limited Partnership in the form of Exhibit V attached hereto (the "Amended
Transferor Partnership Certificate") pursuant to which the BRI Partnership, or
its designees, shall be admitted and the Transferor Partners shall withdraw, as
the partners of the Transferor Partnership and be released of all liability
thereunder, and the terms of the Transferor Partnership shall be amended in
accordance with the Amended Transferor Partnership Agreement.

     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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the


                                      -3-
<PAGE>

Transferor 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, a non-imputation 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership 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 Partnership 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 Partnership 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.


                                      -4-

     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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 


                                      -6-
<PAGE>

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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income


                                      -7-
<PAGE>

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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $19,503,043, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated August 1, 1993,
in the original principal amount of $19,024,400 (the "Note") evidencing the loan
(the "Loan") made to the Transferor Partnership by Washington Capital ("Lender")
and secured by the Loan Documents which shall be an obligation of the Transferor
Partnership as of the Closing subject to any exculpation from liability
provisions therein.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."


                                      -8-
<PAGE>

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or
liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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

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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

answered to its satisfaction.

     (f) Such Transferor Partner acknowledges and agrees that:

          (i) the BRI Partnership Units to be acquired by it hereunder will not

subsequent to the Closing Date, resulting from (A) any inaccuracy in or breach
of any representation or warranty of the Transferor Partnership set forth in

resulting from any breach or default by the Transferor Partnership or such
Transferor Partner of any obligation of the Transferor Partnership or such

representations of each of the Transferor Partners in Section 5.34, which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor

resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor


                                      -40-
<PAGE>

Partner under Section 10.05(b)(i) for any amounts in excess of 50% of the fair

Partnership, respectively, with respect to any representation or warranty, shall

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 any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section

Transferor Agent to permit the Transferor Partnership to prepare such returns or
to respond to any audits or assessments for the periods covered by such returns.

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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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


                                      -44-
<PAGE>

to allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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:


                                      -45-
<PAGE>

     (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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor


                                      -46-
<PAGE>

Partner, and (iii) the number of the Restricted Distribution BRI Partnership
Units to be received by each Transferor Partner. The BRI Partnership shall have
no obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the


                                      -47-
<PAGE>

Transferor Partners to adjust for such amounts owing by the Transferor Partners
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 Partners,
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 Partners 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 Partnership shall have elected to settle
adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such distribution of surplus cash
relates only to the period prior to the Closing Date, all such surplus cash
shall be distributed to the Transferor Partners prior to Closing; provided
however, if as a result of the 1997 annual HUD audit (it being agreed that the
BRI Partnership shall consult with the Transferor Agent during the HUD audit
procedure), HUD (after final adjudication by regulatory and judicial
authorities) determines that all or any portion of such distribution of surplus
cash to the Transferor Partners was improper, the Transferor Partners,
severally, agree to reimburse the Transferor Partnership immediately upon demand
for all amounts so designated by HUD as improper and to indemnify, defend and
hold the Transferor Partnership and the BRI Partnership harmless from and
against all loss, cost, damage or expense (including reasonable legal fees)
suffered or incurred as a result of such improper distribution of surplus cash.
In all other cases, there shall be no adjustment at Closing regarding surplus
cash, but at such time as HUD approves the distribution of surplus cash for
fiscal 1997, the BRI Partnership shall receive all such surplus cash and
thereafter the BRI Partnership shall promptly pay to the Transferor Agent, as
distribution agent for the Transferor Partners, the Transferor Partners pro-rata
share of such surplus cash allocable to the period prior to the Closing Date.


                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled 


                                      -48-
<PAGE>

closing the Transferor Partnership Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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 Transferor Partnership Interests in accordance with the terms of
this Agreement and the Transferor Partners willfully refuse to perform the
Transferor Partners' obligations hereunder, the BRI Partnership, at its option,
shall have the right to compel specific performance by the Transferor Partners
hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to


                                      -49-
<PAGE>

compel specific performance by the BRI Partnership hereunder, in which event the
Transferor Partners 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 Partners in connection with the exercise of their
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
Partners in the event of a default by the BRI Partnership in lieu of all other
rights and remedies which the Transferor Partners may have against the BRI
Partnership at law or in equity.


                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

                                      -54-
<PAGE>

Transferor Partners, to the transfer of ownership of the Transferor Partnership
to the BRI Partnership and to obtain the Lender Estoppel Letter. The Transferor
Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership and the transfer of
ownership of the Transferor Partnership to the BRI Partnership. The BRI
Partnership shall supply any and all documentation and additional information
required by Lender in order to promptly complete the request for the consent of
Lender to the transactions contemplated hereunder. The Transferor Partnership
shall request that Lender state in writing any terms and requirements, including
the amount of any Loan Assumption Fees, to be imposed by Lender in connection
with its consent to the transactions contemplated hereby. It shall be a
condition of Closing that prior to October 15, 1997, Lender shall have granted
its consent to the transactions contemplated hereunder on terms and requirements
reasonably satisfactory to the BRI Partnership, shall have issued the Lender
Estoppel Letter and shall have agreed to release the Transferor Partners from
all liability under the Loan Documents. In the event that any of the terms or
requirements required by Lender for its consent are not approved by the BRI
Partnership, the BRI Partnership may terminate this Agreement by written notice
given to the Transferor Partners within fifteen (15) business days after the BRI
Partnership have received in writing the terms and requirements of Lender for
its consent. In the event either (a) the consent of Lender is not obtained prior
to the Closing or (b) the BRI Partnership does not approve the terms and
conditions of Lender, including the amount of any Loan Assumption Fees in excess
of 1% of the unpaid principal balance, and the BRI Partnership gives timely
notice of termination hereunder to the Transferor Agent, this Agreement shall
terminate without further action by any party, and, thereafter this Agreement
shall be void and without recourse to all parties, except for provisions which
are expressly stated to survive termination of this Agreement. In the event the
Lender shall not have agreed to release the Transferor Partners from all
liability under the Loan Documents or the Lender shall have placed terms and
conditions on the Transferor Partners that are unacceptable to them, the
Transferor Agent may terminate this Agreement by written notice given to the BRI
Partnership within fifteen (15) business days after the Transferor Agent has
received in writing notice that the Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions. If the Transferor Agent gives timely notice
of termination to the BRI Partnership, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of 


                                      -55-
<PAGE>

common stock or other equity securities of BRI (the "Public Offering"), or (ii)
a private placement of common stock or other equity securities of BRI (the
"Private Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI


                                      -56-
<PAGE>

Partnership will not take possession of the Transferor Partnership or the
Property nor assume the burdens and benefits of project ownership prior to such
approval by HUD.

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives 


                                      -57-
<PAGE>

timely notice of termination hereunder to the Transferor Partners, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

                        ADDITIONAL PROVISIONS RELATING TO
                             THE TRANSFEROR PARTNERS

                                      -60-
<PAGE>

Transferor Partners pursuant to the terms of this Agreement. Each Transferor
Partner and the Transferor Partnership hereby agrees that the fees and expenses
attributable to this transaction will be divided into two categories: (i) those

contained herein, for the proposes of this Section 19.03, each of the Transferor
Partners hereby agrees that: (i) QPI shall be entitled to an aggregate
administrative fee of $200,000 in connection with the concurrent contribution of

the "Related Entities"), which shall be 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

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. Each of the Transferor
Partners acknowledges and agrees that (i) any and all Direct Costs shall be
allocated based on the pro rata number of BRI Partnership Units allocated to
each of them with respect to their interest in the Transferor Partnership and
(ii) any and all Indirect Costs shall be allocated among the Transferor Partners
and the Related Entities at Closing based on the pro rata number of BRI
Partnership Units allocated at Closing to each of them. Each of the Transferor
Partners 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

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 each Transferor Partner 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
Partners to the BRI Partnership.

     19.06 Release and Indemnification by and between each Transferor Partner,
the Transferor Agent and certain Affiliates thereof. By executing this
Agreement, each of the Transferor Partners (i) consents to the transactions

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in

Insurance 


                                       -3-

<PAGE>


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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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, a non-imputation
endorsement, a fairways 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of 



                                       -4-

<PAGE>



(A) ten (10) days after the Transferor Partnership 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 Partnership
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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to



                                       -5-

<PAGE>



cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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


                                       -6-

<PAGE>



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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 



                                       -7-

<PAGE>



damage claims made by tenants as to which thetime 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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $1,108,230, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of The Patrician
Financial Company ("Lender"), securing the outstanding principal balance of the
Note dated October 29, 1996, in the original principal amount of $825,000 (the
"Note") evidencing the loan (the "Loan") made to the Borrower Partnership by
Lender. The Loan is also secured by the other Loan Documents (as defined in
Section 5.20 hereof) which shall be an obligation of the Borrower Partnership
and the Transferor Partnership as of the Closing subject to any exculpation from
liability provisions therein. The Transferor Partnership shall also remain as
obligor of the outstanding principal balance of the note dated October 29, 



                                       -8-

<PAGE>



1996 in the original principal amount of the Note (the "Borrower Partnership
Note"), evidencing the loan made to the Transferor Partnership by the Borrower
Partnership (the "Borrower Partnership Loan").

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner 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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership
owes any amounts to the Transferor Partners 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 each Transferor Partner pursuant to Section 12.04. The
Transferor Agent shall be liable to distribute the BRI Partnership Units and if
applicable, a pro-rata share of the BRI Additional Payment to each of the
Transferor Partners in accordance with the Transferor Allocation Schedule. The
BRI Partnership shall have no obligation or liability with respect to the
preparation or accuracy of the Preliminary Transferor Allocation Schedule or the
Transferor Allocation Schedule or the distribution of the BRI Partnership Units
or the BRI Additional Payment, if applicable, to the Transferor Partners and the
Transferor Partners hereby release the BRI Partnership from any such obligation
or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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,

replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

                                   THE CLOSING

LLP, 60 State Street, Boston, Massachusetts 02109, or such other place as the
Transferor Partnership 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 all Transferor Partners 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

Agreement.

     (b) Such Transferor Partner understands that the BRI Partnership Units to

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

predicated in part on the accuracy and completeness of the representations and
warranties of such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons

Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such that it is able to bear all risks of the

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.

(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) Such Transferor Partner 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

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

     (a) The Transferor Partners' Indemnity. In the event the parties proceed to
Closing, each Transferor Partner agrees, severally and not jointly, to indemnify
and hold the BRI Partnership harmless against and with respect to (i) any loss
or damage (including reasonable attorney's fees) to the BRI Partnership

Section 5A or Section 5C, or of such Transferor Partner set forth in Section 5B
or of the Borrower Corporate General Partner set forth in Section 5D, or (B)
resulting from any breach or default by the Transferor Partnership, such
Transferor Partner or the Borrower Corporate General Partner of any obligation
of the Transferor Partnership, such Transferor Partner or the Borrower Corporate
General Partner under this Agreement or (ii) from liabilities for borrowed money
(other than the payments under the Loan due after the Closing) incurred by the
Transferor Partnership, the Borrower Partnership, the Borrower Corporate General
Partner or the Property prior to the Closing; provided that no Transferor
Partner shall be required to indemnify the BRI Partnership for any amounts in
excess of 50% of the fair market value of the BRI Partnership Units received by
such Transferor Partner as of the date such indemnification obligation is
satisfied (except for indemnification obligations with respect to
representations of each of the Transferor Partners in Section 5.34, which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner) (collectively, the "Cap"); and provided further that to the extent any
of the Transferor Partners have any indemnification obligation to the BRI
Partnership, the Transferor Partners may elect to satisfy such indemnification
obligation by directing the BRI Partnership to cancel such amount of BRI
Partnership Units acquired by such Transferor Partner pursuant to this Agreement
having a fair market value (measured at the time such BRI Partnership Units are
returned or cancelled) equal to the indemnification obligation of such
Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including
reasonable attorney's fees) to the Transferor Partners, subsequent to the
Closing Date, resulting from (A) any inaccuracy in or breach of any
representation or warranty of the BRI Partnership or (B) resulting from any
breach or default by the BRI Partnership of any obligation of the BRI
Partnership under this Agreement or (ii) from liabilities of the Transferor
Partnership or the Property after the Closing (except for such liabilities
resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor Partner under Section 10.05(b)(i) for any amounts in excess of 50% of
the fair market value as of the date such indemnification obligation is
satisfied of the BRI Partnership Units received by such Transferor Partner
(except for indemnification obligations with 



                                      -47-

<PAGE>



respect to Sections 6.10 and 11.03 which shall be limited to 100% of the fair
market value as of the date such indemnification obligation is satisfied of the
BRI Partnership Units received by such Transferor Partner).

     (c) The indemnification obligations of the Transfer Partners and the BRI
Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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 any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section
708(b)(1)(B) of the Code and its tax year shall close on the Closing Date. The
Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be

and provisions of this Agreement and provided further, that prior to the filing
thereof the Transferor Agent shall submit the terminating tax returns to the BRI
Partnership for its review and approval, which shall not be unreasonably
withheld or delayed. The BRI Partnership shall assist the Transferor Agent in
obtaining such data and information regarding the Transferor Agent to permit the
Transferor Partnership to prepare such returns or to respond to any audits or
assessments for the periods covered by such returns.

this Section 11.01(h) shall survive the Closing indefinitely.

satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on

of the

<PAGE>



BRI Partnership Units received by the Transferor Partners 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 either
the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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



                                      -52-

<PAGE>



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

     12.01 Apportionments. The following apportionments shall be made between

settled in accordance with the provisions of 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,

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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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

Maryland.



                                      -53-

<PAGE>



     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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transferor Allocation Schedule (the "Transferor Allocation Schedule"), which
shall be based upon the Preliminary Transferor Allocation Schedule, shall
incorporate all adjustments and prorations to be made pursuant to Section 12,
and shall set forth (i) the name of each Transferor Partner, (ii) the number of
Unrestricted Distribution BRI Partnership Units to be received by each
Transferor Partner, and (iii) the number of Restricted Distribution BRI
Partnership Units to be received by each Transferor Partner. The BRI Partnership
shall have no obligation or liability with respect to the preparation or
accuracy of the Preliminary Transferor Allocation Schedule or the Transferor
Allocation Schedule or the distribution of the BRI Partnership Units or the BRI
Additional Payment, if applicable, to the Transferor Partners and the Transferor
Partners hereby release the BRI Partnership from any such obligation or
liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners in
collecting such rent. Rents received from such tenant after the Closing shall be
applied in the following order of 



                                      -54-

<PAGE>



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
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
cause the Transferor Partnership to 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
Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or the Property does not conform with the 



                                      -55-

<PAGE>



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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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 Transferor Partnership Interests in accordance with the terms of
this Agreement and the Transferor Partners willfully refuse to perform the
Transferor Partners' obligations hereunder, the BRI Partnership, at its option,
shall have the right to compel specific performance by the Transferor Partners
hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the 



                                      -56-

<PAGE>



Transferor Partners 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 Partners in connection with the exercise of their
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
Partners in the event of a default by the BRI Partnership in lieu of all other
rights and remedies which the Transferor Partners may have against the BRI
Partnership at law or in equity.

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the

hereunder to the Transferor Agent, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement. In the event the Lender shall
not have agreed to release the Transferor Partners from all liability under the
Loan Documents or the Lender shall have placed terms and conditions on the

     19.03 Allocation of Transaction Costs. Each Transferor Partner hereby
acknowledge and agrees that a portion of the amount due to such Transferor
Partner will be used to pay the fees and expenses attributable to the
transaction contemplated by this Agreement, which fees and expenses are the
several obligations of the Transferor Partners pursuant to the terms of this
Agreement. Each Transferor Partner and the Transferor Partnership hereby agrees
that the fees and expenses attributable to this transaction will be divided into

Notwithstanding anything to the contrary contained herein, for the proposes of

shall be entitled to an aggregate administrative fee of $200,000 in connection

shall be 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

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. Each of the Transferor Partners acknowledges and agrees that
(i) any and all Direct Costs shall be allocated based on the pro rata number of
BRI Partnership Units allocated to each of them with respect to their interest
in the Transferor Partnership and (ii) any and all Indirect Costs shall be
allocated among the Transferor Partners and the Related Entities at Closing
based on the pro rata number of BRI Partnership Units allocated at Closing to
each of them. Each of the Transferor Partners 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.

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its

Limited Partnership in the form of Exhibit V attached hereto (the "Amended

its designees, shall be admitted and the Transferor Partners shall withdraw, as
the partners of the Transferor Partnership and be released of all liability

accordance with the Amended Transferor Partnership Agreement.

     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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the 


                                      -3-
<PAGE>

Transferor Partnership and shall be in the amount of the Consideration Amount

endorsement, a non-imputation 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership 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 Partnership 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 Partnership 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

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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership or (ii) waive such survey matters and accept title
subject thereto, in which event there shall be no reduction in the Consideration
Amount.

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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 


                                      -6-
<PAGE>

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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income


                                      -7-
<PAGE>

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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.


                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $13,536,318, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated November 18,
1985, as amended through a certain Fourth Allonge Deed of Trust Note dated as of
January 25, 1994, in the original principal amount of $12,258,600 (the "Note")
evidencing the loan (the "Loan") made to the Transferor Partnership by CPC
Mortgage Capital, LLC ("Lender") and secured by the Loan Documents which shall
be an obligation of the Transferor Partnership as of the Closing subject to any
exculpation from liability provisions therein.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted


                                      -8-
<PAGE>

Distribution BRI Partnership Units are collectively referred to herein as the
"BRI Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or
liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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


                                      -9-
<PAGE>

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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

Improvements or any material portion thereof (having a replacement cost equal to
or in excess of $750,000.00) are damaged or destroyed by fire or casualty, or if

for provisions which are expressly stated to survive such termination, or (ii)
proceed with the transaction contemplated hereby in which event there shall be a

resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor 


                                      -40-
<PAGE>

Partner under Section 10.05(b)(i) for any amounts in excess of 50% of the fair
market value as of the date such indemnification obligation is satisfied of the
BRI Partnership Units received by such Transferor Partner (except for
indemnification obligations with respect to Sections 6.10 and 11.03 which shall
be limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Partnership Units received by such Transferor
Partner).

     (c) The indemnification obligations of the Transfer Partners and the BRI
Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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 any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section

                                      -41-
<PAGE>

708(b)(1)(B) of the Code and its tax year shall close on the Closing Date. The
Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be
filed by or on behalf of the Transferor Partnership with respect to all tax
years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,
which shall not be unreasonably withheld or delayed. The BRI Partnership shall
assist the Transferor Agent in obtaining such data and information regarding the
Transferor Agent to permit the Transferor Partnership to prepare such returns or
to respond to any audits or assessments for the periods covered by such returns.


                                   SECTION 11

connection with the issuance of the BRI Partnership Units to the Transferor

this Section 11.01(h) shall survive the Closing indefinitely.


                                      -43-

        11.02 Partnership's Expenses. The BRI Partnership shall pay its own
counsel fees, and all loan assumption fees (not to exceed 1% of the outstanding
loan balance) and one-half of all (i) Title Insurance and Survey costs, (ii)
escrow and recording costs and (iii) transfer taxes and documentary stamps, if
any, and (iv) UCC search costs.

     11.03 Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Partners, in their
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Partnership has not dissolved, terminated or liquidated, the right to
receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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 


                                      -44-
<PAGE>

to allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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:


                                      -45-
<PAGE>

     (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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor 


                                      -46-
<PAGE>

Partner, and (iii) the number of the Restricted Distribution BRI Partnership
Units to be received by each Transferor Partner. The BRI Partnership shall have
no obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the 


                                      -47-
<PAGE>

Transferor Partners to adjust for such amounts owing by the Transferor Partners
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 Partners,
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 Partners 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 Partnership shall have elected to settle
adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such distribution of surplus cash
relates only to the period prior to the Closing Date, all such surplus cash
shall be distributed to the Transferor Partners prior to Closing; provided
however, if as a result of the 1997 annual HUD audit (it being agreed that the
BRI Partnership shall consult with the Transferor Agent during the HUD audit
procedure), HUD (after final adjudication by regulatory and judicial
authorities) determines that all or any portion of such distribution of surplus
cash to the Transferor Partners was improper, the Transferor Partners,
severally, agree to reimburse the Transferor Partnership immediately upon demand
for all amounts so designated by HUD as improper and to indemnify, defend and
hold the Transferor Partnership and the BRI Partnership harmless from and
against all loss, cost, damage or expense (including reasonable legal fees)
suffered or incurred as a result of such improper distribution of surplus cash.
In all other cases, there shall be no adjustment at Closing regarding surplus
cash, but at such time as HUD approves the distribution of surplus cash for
fiscal 1997, the BRI Partnership shall receive all such surplus cash and
thereafter the BRI Partnership shall promptly pay to the Transferor Agent, as
distribution agent for the Transferor Partners, the Transferor Partners pro-rata
share of such surplus cash allocable to the period prior to the Closing Date.


                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled 


                                      -48-
<PAGE>

closing the Transferor Partnership Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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 Transferor Partnership Interests in accordance with the terms of
this Agreement and the Transferor Partners willfully refuse to perform the
Transferor Partners' obligations hereunder, the BRI Partnership, at its option,
shall have the right to compel specific performance by the Transferor Partners
hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to 


                                      -49-
<PAGE>

compel specific performance by the BRI Partnership hereunder, in which event the
Transferor Partners 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 Partners in connection with the exercise of their
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
Partners in the event of a default by the BRI Partnership in lieu of all other
rights and remedies which the Transferor Partners may have against the BRI
Partnership at law or in equity.


                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

<PAGE>

Transferor Partners, to the transfer of ownership of the Transferor Partnership

Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership and the transfer of
ownership of the Transferor Partnership to the BRI Partnership. The BRI
Partnership shall supply any and all documentation and additional information
required by Lender in order to promptly complete the request for the consent of
Lender to the transactions contemplated hereunder. The Transferor Partnership
shall request that Lender state in writing any terms and requirements, including
the amount of any Loan Assumption Fees, to be imposed by Lender in connection
with its consent to the transactions contemplated hereby. It shall be a
condition of Closing that prior to October 15, 1997, Lender shall have granted
its consent to the transactions contemplated hereunder on terms and requirements
reasonably satisfactory to the BRI Partnership, shall have issued the Lender
Estoppel Letter and shall have agreed to release the Transferor Partners from

Partnership, the BRI Partnership may terminate this Agreement by written notice
given to the Transferor Partners within fifteen (15) business days after the BRI
Partnership have received in writing the terms and requirements of Lender for

to the Closing or (b) the BRI Partnership does not approve the terms and
conditions of Lender, including the amount of any Loan Assumption Fees in excess
of 1% of the unpaid principal balance, and the BRI Partnership gives timely

liability under the Loan Documents or the Lender shall have placed terms and
conditions on the Transferor Partners that are unacceptable to them, the
Transferor Agent may terminate this Agreement by written notice given to the BRI
Partnership within fifteen (15) business days after the Transferor Agent has
received in writing notice that the Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions. If the Transferor Agent gives timely notice
of termination to the BRI Partnership, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of


                                      -55-
<PAGE>

common stock or other equity securities of BRI (the "Public Offering"), or (ii)
a private placement of common stock or other equity securities of BRI (the
"Private Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI 


                                      -56-
<PAGE>

Partnership will not take possession of the Transferor Partnership or the
Property nor assume the burdens and benefits of project ownership prior to such
approval by HUD.

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives 


                                      -57-
<PAGE>

timely notice of termination hereunder to the Transferor Partners, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

$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

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. Each of the Transferor
Partners acknowledges and agrees that (i) any and all Direct Costs shall be
allocated based on the pro rata number of BRI Partnership Units allocated to
each of them with respect to their interest in the Transferor Partnership and
(ii) any and all Indirect Costs shall be allocated among the Transferor Partners
and the Related Entities at Closing based on the pro rata number of BRI
Partnership Units allocated at Closing to each of them. Each of the Transferor
Partners 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.

Agent is authorized on behalf of each Transferor Partner to hold all such
agreements in escrow pending the Closing, at which time the Transferor Agent

Partners to the BRI Partnership.

sufficiency of which are hereby acknowledged, the Transferor Partners and the
BRI Partnership hereby covenant and agree as follows:

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its

                                       -3-

<PAGE>



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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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, a non-imputation
endorsement, a fairways 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of



                                       -4-

<PAGE>



(A) ten (10) days after the Transferor Partnership 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 Partnership
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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to



                                       -5-

cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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



                                       -6-

<PAGE>



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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 



                                       -7-

<PAGE>



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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $6,642,632, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing, and minus (Z) the amount required to pay the various outstanding
loans owed by the Transferor Partnership to the Transferor Partners or their
affiliates or to other third-party lenders (the "Other Loans"), but in any
event, the total amount to be deducted under this clause (Z) shall not exceed an
amount equal to the difference between the Consideration Amount minus the
outstanding principal balance of the Note (the "Other Loans BRI Cap").

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of The Patrician
Financial Company ("Lender"), securing the outstanding principal balance of the
Note dated November 27, 1996, in the original principal amount of $6,137,000
(the "Note") evidencing the loan (the



                                       -8-

<PAGE>



"Loan") made to the Borrower Partnership by Lender. The Loan is also secured by
the other Loan Documents (as defined in Section 5.20 hereof) which shall be an
obligation of the Borrower Partnership and the Transferor Partnership as of the
Closing subject to any exculpation from liability provisions therein. The
Transferor Partnership shall also remain as obligor of the outstanding principal
balance of the note dated November 27, 1996 in the original principal amount of
the Note (the "Borrower Partnership Note"), evidencing the loan made to the
Transferor Partnership by the Borrower Partnership (the "Borrower Partnership
Loan"). At the Closing, the BRI Partnership shall pay the amount required to
satisfy the Other Loans, provided that the amount to be paid by the BRI
Partnership shall not exceed the Other Loans BRI Cap. If the amount paid by the
BRI Partnership is not sufficient to pay the Other Loans in full, the Transferor
Partnership shall pay, from funds otherwise allocable under this Agreement to
the Transferor Partners, all additional amounts required to pay off the Other
Loans in full. At least fifteen (15) days prior to the Closing, the Transferor
Agent shall deliver a pay-off letter from each holder of an Other Loan stating
the amount required to pay-off such Other Loan in full, and at Closing, the
Transferor shall deliver the original note evidencing each such Other Loan
marked "Paid in Full," or in the event that the original of any such note is not
available, such other evidence of the satisfaction of such note and release of
liability under such Other Loan as the BRI Partnership may require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner would be entitled
to a 



                                       -9-

<PAGE>



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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership
owes any amounts to the Transferor Partners 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 each Transferor Partner pursuant to Section 12.04. The
Transferor Agent shall be liable to distribute the BRI Partnership Units and if
applicable, a pro-rata share of the BRI Additional Payment to each of the
Transferor Partners in accordance with the Transferor Allocation Schedule. The
BRI Partnership shall have no obligation or liability with respect to the
preparation or accuracy of the Preliminary Transferor Allocation Schedule or the
Transferor Allocation Schedule or the distribution of the BRI Partnership Units
or the BRI Additional Payment, if applicable, to the Transferor Partners and the
Transferor Partners hereby release the BRI Partnership from any such obligation
or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each 



                                      -10-

Transferor Partner 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
Partners 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
Partners a certified copy of the Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

and in good standing under the laws of the State of Maryland. The Transferor
Partnership has all requisite power to own and operate the Property and to carry

violation of any order, statute, rule or regulation applicable to it, except for
such violations which would not have a Material Adverse Effect. Neither the

Partners, nor the contribution of the Transferor Partnership Interests by the
Transferor Partners hereunder, will result in any Material Adverse Effect or be
in conflict with or constitute a default under the Transferor Partnership
Agreement or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Transferor Partnership,
except for Permitted Exceptions.

     5.03 Governmental Consent, etc. Except for the requirement for the receipt
of the Lender approval in accordance with the provisions of Section 17.03, no

right to purchase or acquire or to issue or distribute to any of the Transferor
Partners, any evidences of indebtedness or assets; and the Transferor

material action, suit or, to the Transferor Partnership's knowledge, proceeding
or investigation pending or, to the Transferor Partnership's knowledge, any
threat thereof, against the Transferor Partners, the Transferor Partnership, the
Borrower Partnership or the Property or any part thereof which questions the
validity of this Agreement or the right of the Transferor Partners 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 Partnership or the
Borrower Partnership, as such is presently contemplated; or (ii) the rights
represented by the Transferor Partnership Interests or the partnership interests
in the Borrower Partnership. During the period commencing on the date hereof and

                  C. ADDITIONAL REPRESENTATIONS AND WARRANTIES
                      WITH RESPECT TO BORROWER PARTNERSHIP

     The Transferor Partnership represents, warrants and covenants to the BRI
Partnership as of the date hereof as follows:

     5.37 Organization and Standing of the Borrower Partnership. The Borrower
Partnership is a general partnership duly organized, validly existing and in
good standing under the laws of the State of Maryland. The Borrower Partnership
has all requisite power to maintain the Loan from Lender and to maintain the
Borrower Partnership Loan to the Transferor Partnership and to carry on its
business as presently being conducted and as proposed to be conducted. The
Borrower Partnership is duly qualified to do business in all jurisdictions in
which the failure to be so qualified would have a Material Adverse Effect on the
Borrower Partnership's business.

     5.38 Compliance with Other Instruments, etc. The Borrower Partnership is
not in violation of any term contained in the Borrower Partnership Agreement, or
to the Transferor Partnership's knowledge in any other material instrument or
contract to which the Borrower Partnership is a party, and to the Transferor
Partnership's knowledge the Borrower Partnership is not in violation of any
order, statute, rule or regulation applicable to it, except for such violations
which would not have a Material Adverse Effect. Neither the execution, delivery
and performance of this Agreement by the Transferor Partnership, nor the
contribution of the Transferor Partnership Interests by the Transferor Partners
hereunder, nor the assignment and transfer of the Borrower General Partnership
Interest by the Borrower Corporate General Partner to the Borrower LLC General
Partner will result in any Material Adverse Effect or be in conflict with or
constitute a default under the Borrower Partnership Agreement or result in the
creation of any mortgage, pledge, lien, encumbrance or charge upon any of the
properties or assets of the Borrower Partnership.

     5.39 Partnership Capitalization. The Borrower Partnership Agreement (i) is
the only agreement among the partners thereto relating to the organization,
operation, or management of the Borrower Partnership, (ii) is in full force and
effect and (iii) has not been amended or modified. The Transferor Partnership
and the Borrower Corporate General Partner are the sole partners of the Borrower
Partnership. The address of the Transferor Partnership and the Borrower
Corporate General Partner is



                                      -27-

<PAGE>


124 Slade Avenue, Suite 200, Baltimore, Maryland 21208. Each of the Transferor
Partnership and the Borrower Corporate General Partner owns a 50% general
partnership interest in the Borrower Partnership. No partner of the Borrower

representations of each of the Transferor Partners in Section 5.34, which shall

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.

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

party on or prior to Closing.

BRI Partnership.

     (h) Other Documents. Such other documents, instruments or agreements which
the BRI Partnership is required to deliver to the Transferor Partners pursuant
to any other provisions of this Agreement or which the Transferor Partners may,
either at or subsequent to the Closing, deem reasonably necessary in order to



                                      -51-

<PAGE>



consummate the transactions contemplated by this Agreement or to better vest in
the Transferor Partners 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 all loan assumption fees (not to exceed 1% of the outstanding loan
balance) and one-half of all (i) Title Insurance and Survey costs, (ii) escrow
and recording costs and (iii) transfer taxes and documentary stamps, if any, in
connection with the assignment and transfer of the Transferor Partnership
Interests as contemplated herein, and (iv) UCC search costs.

     11.03 Post-Closing Agreements of the BRI Partnership.

     (a) The BRI Partnership hereby grants the Transferor Partners, in their
capacity as a limited partner of the BRI Partnership and so long as the
Transferor Partnership has not dissolved, terminated or liquidated, the right to
receive the Transferor Partnership Interests as a distribution in kind in
satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the 



                                      -52-


<PAGE>



Loan Documents, or change the terms in a manner that would change the Loan from
nonrecourse to recourse within the meaning of Section 752 of the Code and the
regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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 the provisions of 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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 



                                      -54-

<PAGE>



prorations to be made pursuant to this Section 12. Transferor Agent and the BRI
Partnership shall cooperate in the furnishing of all information and
documentation necessary to prepare such calculations. Prior to Closing, the
Transferor Agent shall deliver to the BRI Partnership the final Transferor
Allocation Schedule (the "Transferor Allocation Schedule"), which shall be based
upon the Preliminary Transferor Allocation Schedule, shall incorporate all
adjustments and prorations to be made pursuant to Section 12, and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transferor Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership shall assign and
deliver to the BRI Partnership all of the tenant security deposits, including
interest accrued 



                                      -55-

<PAGE>



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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners shall be in
default under this Agreement and the BRI Partnership shall be entitled to
terminate this Agreement by written notice



                                      -56-

<PAGE>



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 Transferor
Partnership Interests in accordance with the terms of this Agreement and the
Transferor Partners willfully refuse to perform the Transferor Partners'
obligations hereunder, the BRI Partnership, at its option, shall have the right
to compel specific performance by the Transferor Partners hereunder, in which
event the BRI Partnership shall have the right to recover from the Transferor
Partners 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 Partners in lieu
of all other rights and remedies which the BRI Partnership may have against the
Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership and the BRI Partnership
mutually represent and warrant that neither of them has retained a broker,
finder or 



                                      -57-

<PAGE>



similar agent who might have a claim or right to claim a commission or
fee in connection with this transaction. The Transferor Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

     In the event that any condition set forth in Section 17.02(a) through
Section 17.02(d) hereinabove is neither satisfied nor waived by the Transferor
Agent in writing, on or before the Closing Date, the Transferor Partners shall
be entitled to terminate this Agreement by written notice given to the BRI
Partnership within seven (7) days after such date, and, thereafter this
Agreement shall be void and without recourse to all parties hereunder except for
provisions which are expressly stated to survive termination of this Agreement.

     17.03 Financing Assumption Condition. The BRI Partnership and the
Transferor Partnership shall use reasonable efforts to obtain the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership by the Transferor Partners, to the transfer of ownership of the
Transferor Partnership to the BRI Partnership, to the assignment by the Borrower
Corporate General Partner of all of its interests in the Borrower Partnership to
the Borrower LLC General Partner, to the withdrawal from the Borrower
Partnership of the Borrower Corporate General Partner, and to the admission to
the Borrower Partnership of the Borrower LLC General Partner as a fifty percent
(50%) general partner, and to obtain the Lender Estoppel Letter. The Transferor
Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership, the transfer of
ownership of the Transferor Partnership to the BRI Partnership, to the
assignment by the Borrower Corporate General Partner of all of its interests in
the Borrower Partnership to the Borrower LLC General Partner, to the withdrawal

the admission to the Borrower Partnership of the Borrower LLC General Partner as
a fifty percent (50%) general partner. The BRI Partnership shall supply any and
all documentation and additional information required by Lender in order to
promptly complete the request for the consent of Lender to the transactions
contemplated hereunder. The Transferor Partnership shall request that Lender
state in writing any terms and requirements, including the amount of any Loan
Assumption Fees, to be imposed by Lender in connection with its consent to the
transactions contemplated hereby. It shall be a condition of Closing that prior
to October 15, 1997, Lender shall have granted its consent to the transactions
contemplated hereunder on terms and requirements reasonably satisfactory to the
BRI Partnership, shall have issued the Lender Estoppel Letter and shall have
agreed to release the Transferor Partners from all liability under the Loan
Documents. In the event that any of the terms or requirements required by Lender
for its consent are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership have received in
writing the terms and requirements of Lender for its consent. In the event
either (a) the consent of Lender is not obtained prior to the Closing or (b) the
BRI Partnership does not approve the terms and conditions of Lender, including
the amount of any Loan Assumption Fees in excess of 1% of the unpaid 



                                      -63-

<PAGE>



principal balance, and the BRI Partnership gives timely notice of termination
hereunder to the Transferor Agent, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement. In the event the Lender shall
not have agreed to release the Transferor Partners from all liability under the
Loan Documents or the Lender shall have placed terms and conditions on the
Transferor Partners that are unacceptable to them, the Transferor Agent may
terminate this Agreement by written notice given to the BRI Partnership within
fifteen (15) business days after the Transferor Agent has received in writing
notice that the Lender has refused to release the Transferor Partners from
liability under the Loan Documents or has imposed such unacceptable terms and
conditions. If the Transferor Agent gives timely notice of termination to the
BRI Partnership, this Agreement shall terminate without further action by any
party, and, thereafter this Agreement shall be void and without recourse to all
parties, except for provisions which are expressly stated to survive termination
of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private placement of common stock or other equity
securities of BRI (the "Private Placement"). The Transferor Partners shall
supply any documentation and additional information required by BRI in order to
complete the offering materials in connection with the Public Offering or the
Private Placement. The obligation of the BRI Partnership to proceed with the
Closing of the transactions contemplated by this Agreement is expressly
conditioned upon the successful completion of the Public Offering and the
Private Placement raising a minimum of $75,000,000.00. If the Public Placement
and the Private Placement do not in the aggregate complete offerings which raise
a minimum of $75,000,000 as aforesaid prior to the Closing Date hereunder, the
BRI Partnership shall have the right to terminate this Agreement effective as of
the Closing Date, and, thereafter this Agreement 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 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 



                                      -64-

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.

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. Each Transferor Partner hereby
acknowledge and agrees that a portion of the amount due to such Transferor
Partner will be used to pay the fees and expenses attributable to the
transaction contemplated by this Agreement, which fees and expenses are the
several obligations of the Transferor Partners pursuant to the terms of this
Agreement. Each Transferor Partner and the Transferor Partnership hereby agrees

shall be 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

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. Each of the Transferor Partners acknowledges and agrees that
(i) any and all Direct Costs shall be allocated based on the pro rata number of
BRI Partnership Units allocated to each of them with respect to their interest
in the Transferor Partnership and (ii) any and all Indirect Costs shall be
allocated among the Transferor Partners and the Related Entities at Closing
based on the pro rata number of BRI Partnership Units allocated at Closing to
each of them. Each of the Transferor Partners 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.

Corporate General Partner acknowledge and agree 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 each Transferor Partner and the Borrower Corporate General Partner
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 Partners and the Borrower Corporate General Partner to the BRI
Partnership.

     19.06 Release and Indemnification by and between each Transferor Partner,
the Transferor Agent and certain Affiliates thereof. By executing this

<PAGE>


     WHEREAS, in exchange for such contribution, the Transferor Partners desire

and the BRI Partnership Agreement.

     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 Partners and the
BRI Partnership hereby covenant and agree as follows:


                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its
designees, shall execute and deliver an Amended and Restated Agreement of
Limited Partnership in the form of Exhibit IV attached hereto (the "Amended
Transferor Partnership Agreement") and an Amended and Restated Certificate of
Limited Partnership in the form of Exhibit V attached hereto (the "Amended
Transferor Partnership Certificate") pursuant to which the BRI Partnership, or
its designees, shall be admitted and the Transferor Partners shall withdraw, as
the partners of the Transferor Partnership and be released of all liability
thereunder, and the terms of the Transferor Partnership shall be amended in
accordance with the Amended Transferor Partnership Agreement.

     1.02 Property Title. On or before September 5, 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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the


                                      -3-
<PAGE>

Transferor 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, a non-imputation 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 Partnership on or before September 5, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership 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 Partnership 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 Partnership 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.


                                      -4-

     1.03 Survey. On or before September 5, 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 Partnership promptly after its receipt 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 Partnership on or
before September 5, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 


                                      -6-
<PAGE>

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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income 


                                      -7-
<PAGE>

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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.


                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $14,407,465, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing and, minus (Z) the amount required to pay the various outstanding
loans owed by the Transferor Partnership to the Transferor Partners or their
affiliates or to other third-party lenders (the "Other Loans"), but in any
event, the total amount to be deducted under this clause (Z) shall not exceed an
amount equal to the difference between the Consideration Amount minus the
outstanding principal balance of the Note (the "Other Loans BRI Cap").

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated June 16, 1987, in
the original principal amount of $12,750,000 (the "Note") evidencing the loan
(the "Loan") made to the Transferor Partnership by Reilly Mortgage Group, Inc.
("Lender") and secured by the Loan Documents which shall be an obligation of the
Transferor Partnership as of the Closing subject to any exculpation from
liability provisions therein.

     At the Closing, the BRI Partnership shall pay the amount required to
satisfy the Other Loans, provided that the amount to be paid by the BRI
Partnership shall not exceed the Other Loans BRI Cap. If the amount paid by the
BRI Partnership is not sufficient to pay the Other Loans in full, the Transferor
Partnership shall pay, from funds otherwise allocable under this Agreement to
the Transferor Partners, all 


                                      -8-
<PAGE>

additional amounts required to pay off the Other Loans in full. At least fifteen
(15) days prior to the Closing, the Transferor Agent shall deliver a pay-off
letter from each holder of an Other Loan stating the amount required to pay-off
such Other Loan in full, and at Closing, the Transferor shall deliver the
original note evidencing each such Other Loan marked "Paid in Full," or in the
event that the original of any such note is not available, such other evidence
of the satisfaction of such note and release of liability under such Other Loan
as the BRI Partnership may require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or

                                      -9-
<PAGE>

liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 


                                      -10-
<PAGE>

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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

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 Partnership and the BRI Partnership shall mutually agree, at 10:00

any event not later than October 31, 1997 the ("Closing Date"). The "Time of

referred to in the Commitment in reliance on the execution by the Transferor
Agent pursuant to a Power of Attorney for all Transferor Partners 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

<PAGE>

     (a) Such Transferor Partner 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

Rights Agreement.

     (b) Such Transferor Partner understands that the BRI Partnership Units to
be issued to each Transferor Partner 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 such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons

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.
Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such that it is able to bear all risks of the

affiliates or its other legal counsel and advisors for any explanation of the

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

(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) Such Transferor Partner 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

               will be exempt from registration under the Act and its applicable
               state securities laws"; and

     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.

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

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.

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 on or prior to Closing.

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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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


                                      -45-

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

     12.01 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;


                                      -46-
<PAGE>

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of the Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.


                                      -47-
<PAGE>

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such 


                                      -48-
<PAGE>

distribution of surplus cash relates only to the period prior to the Closing
Date, all such surplus cash shall be distributed to the Transferor Partners
prior to Closing; provided however, if as a result of the 1997 annual HUD audit
(it being agreed that the BRI Partnership shall consult with the Transferor
Agent during the HUD audit procedure), HUD (after final adjudication by
regulatory and judicial authorities) determines that all or any portion of such
distribution of surplus cash to the Transferor Partners was improper, the
Transferor Partners, severally, agree to reimburse the Transferor Partnership
immediately upon demand for all amounts so designated by HUD as improper and to
indemnify, defend and hold the Transferor Partnership and the BRI Partnership
harmless from and against all loss, cost, damage or expense (including
reasonable legal fees) suffered or incurred as a result of such improper
distribution of surplus cash. In all other cases, there shall be no adjustment
at Closing regarding surplus cash, but at such time as HUD approves the
distribution of surplus cash for fiscal 1997, the BRI Partnership shall receive
all such surplus cash and thereafter the BRI Partnership shall promptly pay to
the Transferor Agent, as distribution agent for the Transferor Partners, the
Transferor Partners pro-rata share of such surplus cash allocable to the period
prior to the Closing Date.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners shall be in
default under this Agreement and the BRI Partnership shall be entitled to
terminate this Agreement by written notice


                                      -49-
<PAGE>

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 Transferor
Partnership Interests in accordance with the terms of this Agreement and the
Transferor Partners willfully refuse to perform the Transferor Partners'
obligations hereunder, the BRI Partnership, at its option, shall have the right
to compel specific performance by the Transferor Partners hereunder, in which
event the BRI Partnership shall have the right to recover from the Transferor
Partners 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 Partners in lieu
of all other rights and remedies which the BRI Partnership may have against the
Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

provisions which are expressly stated to survive termination of this Agreement.

     17.03 Financing Assumption Condition. The BRI Partnership and the
Transferor Partnership shall use reasonable efforts to obtain the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership by the Transferor Partners, to the transfer of ownership of the
Transferor Partnership to the 


                                      -55-
<PAGE>

BRI Partnership and to obtain the Lender Estoppel Letter. The Transferor
Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership and the transfer of
ownership of the Transferor Partnership to the BRI Partnership. The BRI
Partnership shall supply any and all documentation and additional information
required by Lender in order to promptly complete the request for the consent of
Lender to the transactions contemplated hereunder. The Transferor Partnership
shall request that Lender state in writing any terms and requirements, including
the amount of any Loan Assumption Fees, to be imposed by Lender in connection
with its consent to the transactions contemplated hereby. It shall be a
condition of Closing that prior to October 15, 1997, Lender shall have granted
its consent to the transactions contemplated hereunder on terms and requirements
reasonably satisfactory to the BRI Partnership, shall have issued the Lender
Estoppel Letter and shall have agreed to release the Transferor Partners from
all liability under the Loan Documents. In the event that any of the terms or
requirements required by Lender for its consent are not approved by the BRI
Partnership, the BRI Partnership may terminate this Agreement by written notice
given to the Transferor Partners within fifteen (15) business days after the BRI
Partnership have received in writing the terms and requirements of Lender for
its consent. In the event either (a) the consent of Lender is not obtained prior
to the Closing or (b) the BRI Partnership does not approve the terms and
conditions of Lender, including the amount of any Loan Assumption Fees in excess
of 1% of the unpaid principal balance, and the BRI Partnership gives timely
notice of termination hereunder to the Transferor Agent, this Agreement shall
terminate without further action by any party, and, thereafter this Agreement
shall be void and without recourse to all parties, except for provisions which
are expressly stated to survive termination of this Agreement. In the event the
Lender shall not have agreed to release the Transferor Partners from all
liability under the Loan Documents or the Lender shall have placed terms and
conditions on the Transferor Partners that are unacceptable to them, the
Transferor Agent may terminate this Agreement by written notice given to the BRI
Partnership within fifteen (15) business days after the Transferor Agent has
received in writing notice that the Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions. If the Transferor Agent gives timely notice
of termination to the BRI Partnership, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private


                                      -56-
<PAGE>

placement of common stock or other equity securities of BRI (the "Private
Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI 


                                      -57-
<PAGE>

Partnership will not take possession of the Transferor Partnership or the
Property nor assume the burdens and benefits of project ownership prior to such
approval by HUD.

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives 


                                      -58-
<PAGE>

timely notice of termination hereunder to the Transferor Partners, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

                                   SECTION 19

                        ADDITIONAL PROVISIONS RELATING TO
                             THE TRANSFEROR PARTNERS

     19.01 Transferor Allocation Schedule. Each Transferor Partner acknowledges

several obligations of the


                                      -61-
<PAGE>

Transferor Partners pursuant to the terms of this Agreement. Each Transferor
Partner and the Transferor Partnership 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 Partnership due to
said fees solely benefiting it ("Direct Costs") and (ii) those fees which cannot

contained herein, for the proposes of this Section 19.03, each of the Transferor
Partners hereby agrees that: (i) QPI shall be entitled to an aggregate
administrative fee of $200,000 in connection with the concurrent contribution of

PPM, by the other Transferor Partnerships and related entities (collectively,
the "Related Entities"), which shall be 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

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. Each of the Transferor
Partners acknowledges and agrees that (i) any and all Direct Costs shall be
allocated based on the pro rata number of BRI Partnership Units allocated to
each of them with respect to their interest in the Transferor Partnership and
(ii) any and all Indirect Costs shall be allocated among the Transferor Partners
and the Related Entities at Closing based on the pro rata number of BRI
Partnership Units allocated at Closing to each of them. Each of the Transferor
Partners 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

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

have executed 


                                      -62-
<PAGE>

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 each Transferor Partner 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
Partners to the BRI Partnership.

     19.06 Release and Indemnification by and between each Transferor Partner,
the Transferor Agent and certain Affiliates thereof. By executing this
Agreement, each of the Transferor Partners (i) consents to the transactions
contemplated by this Agreement, including the transfer of the Transferor
Partnership interest of each of the other Transferor Partners, and waives any

the Transferor Agent and/or the GGC Parties. By executing this Agreement, Morton
Gorn, Stephen Gorn and John Colvin, individually, and on behalf of all of the

<PAGE>

        WHEREAS, in exchange for such contribution, the Transferor Partners
desire to receive BRI Partnership Units in accordance with the terms of this
Agreement and the BRI Partnership Agreement.

        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
Partners and the BRI Partnership hereby covenant and agree as follows:

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the
Transferor Partners, in exchange for BRI Partnership Units and upon the terms
and conditions set forth in this Agreement, the Transferor Partnership
Interests. At the Closing (as defined in Section 3.01), the Transferor Partners
shall, respectively, contribute, assign, transfer and deliver the Transferor
Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in
the form of Exhibit III attached hereto (the "Transferor Assignment").
Immediately thereafter, the Transferor Partners and the BRI Partnership, or its
designees, shall execute and deliver an Amended and Restated Agreement of
Limited Partnership in the form of Exhibit IV attached hereto (the "Amended
Transferor Partnership Agreement") and an Amended and Restated Certificate of
Limited Partnership in the form of Exhibit V attached hereto (the "Amended
Transferor Partnership Certificate") pursuant to which the BRI Partnership, or
its designees, shall be admitted and the Transferor Partners shall withdraw, as
the partners of the Transferor Partnership and be released of all liability
thereunder, and the terms of the Transferor Partnership shall be amended in
accordance with the Amended Transferor Partnership Agreement.

     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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor Partnership and
shall be in the amount of the Consideration Amount (as


                                      -3-
<PAGE>

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, a non-imputation 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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 Partners at Closing. The Transferor Partnership
shall be deemed to have refused to cure any unacceptable exceptions unless the
Transferor Partnership, within ten (10) days after receipt of notice from the
BRI Partnership, shall notify the BRI Partnership in writing that the Transferor
Partnership will attempt to cure such unacceptable exceptions. If the Transferor
Partnership 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 Partnership 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 Partnership
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.


                                      -4-

        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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and tenant files pertaining to the operation of the Property
prior to the Closing. The BRI 


                                      -6-
<PAGE>

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 Partnership's financial records relating to the Property have been
audited, the Transferor Partnership agrees to deliver any reports relating to
such audits to the BRI Partnership. The Transferor Partnership shall provide the
BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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


                                      -7-
<PAGE>

Revenue Code of 1986, as amended (the "Code") (and any analogous state income
tax provisions). The BRI Partnership and the Transferor Partners agree to report
such transaction for federal and applicable state income tax purposes
consistently with the intent set forth in this Section 1.05.


                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be $4,650,000, which shall consist of BRI Partnership Units, to
be issued by the BRI Partnership to the Transferor Partners 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) $4,650,000, 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, and minus (Z) the amount
required to pay the various outstanding loans owed by the Transferor Partnership
to the Transferor Partners or their affiliates or to other third-party lenders
(the "Other Loans"), but in any event, the total amount to be deducted under
this clause (Z) shall not exceed an amount equal to the difference between the
Consideration Amount minus the outstanding principal balance of the Note (the
"Other Loans BRI Cap").

     At the Closing, the BRI Partnership shall pay in full the outstanding
principal balance of the Note dated August __, 1997, in the original principal
amount of $3,450,000 (the "Note") evidencing the loan (the "Loan") made to the
Transferor Partnership by First Union National Bank ("Lender") and secured by
the Loan Documents.

     At the Closing, the BRI Partnership shall pay the amount required to
satisfy the Other Loans, provided that the amount to be paid by the BRI
Partnership shall not exceed the Other Loans BRI Cap. If the amount paid by the
BRI Partnership is not sufficient to pay the Other Loans in full, the Transferor
Partnership shall pay, from funds otherwise allocable under this Agreement to
the Transferor Partners, all additional amounts required to pay off the Other
Loans in full. At least fifteen (15) days prior to the Closing, the Transferor
Agent shall deliver a pay-off letter from each holder 


                                      -8-
<PAGE>

of an Other Loan stating the amount required to pay-off such Other Loan in full,
and at Closing, the Transferor shall deliver the original note evidencing each
such Other Loan marked "Paid in Full," or in the event that the original of any
such note is not available, such other evidence of the satisfaction of such note
and release of liability under such Other Loan as the BRI Partnership may
require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or
liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI 


                                      -9-
<PAGE>

Partnership Units or the BRI Additional Payment, if applicable, to the
Transferor Partners and the Transferor Partners hereby release the BRI
Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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


                                      -10-

be issued to the Transferor Partners 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 transfer.

     2.03 Retention of Escrow. At the Closing, the Transferor Partnership shall
disburse the escrow deposits set forth on Schedule C attached hereto as provided
in Section 12.01.

in any event exceed $25,000.00, and the obligations of the Transferor

resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor Partner under Section 10.05(b)(i) for any amounts in excess of 50% of

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 any of the Transferor Partners shall
have any liability for claims made under Section 10.05(a) or 10.05(b) unless and

$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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

Partnership shall terminate for federal income tax purposes pursuant to Section

data and information regarding the Transferor Agent to permit the Transferor
Partnership to prepare such returns or to respond to any audits or assessments
for the periods covered by such returns.

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.

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:

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of the Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing the BRI Partnership shall hold such cash
as agent for the Transferor Partners, and refund such cash to the Transferor
Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

required to remove all Monetary Liens.

     13.03 Transferor Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners shall be in

terminate this Agreement by written notice given to the Transferor Agent within

hereunder, in which event the BRI Partnership shall have the right to recover
from the Transferor Partners 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
Partners in lieu of all other rights and remedies which the BRI Partnership may
have against the Transferor Partners 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 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 all of the
Transferor Partners desire 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
Partners, jointly, but not severally, at their option, shall have the right to
compel specific performance by the BRI Partnership hereunder, in which event the
Transferor Partners shall have the right to recover from the BRI Partnership the

incurred by the Transferor Partners in connection with the exercise of their
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
Partners in the event of a default by the BRI Partnership in lieu of all other
rights and remedies which the Transferor Partners may have against the BRI
Partnership at law or in equity.

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

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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

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

determine the allocations of the transaction costs and expenses to be allocated
in accordance with the provisions of this Section 19.03.

(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, a non-imputation 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 Partnership on or before September 5, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership 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 Partnership 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 Partnership 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 September 5, 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 Partnership promptly after its receipt 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 Partnership on or
before September 5, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 



                                      -6-
<PAGE>


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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income 



                                      -7-
<PAGE>


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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $15,046,868, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing and, minus (Z) the amount required to pay the various outstanding
loans owed by the Transferor Partnership to the Transferor Partners or their
affiliates or to other third-party lenders (the "Other Loans"), but in any
event, the total amount to be deducted under this clause (Z) shall not exceed an
amount equal to the difference between the Consideration Amount minus the
outstanding principal balance of the Note (the "Other Loans BRI Cap").

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated March 8, 1994, in
the original principal amount of $14,620,000 (the "Note") evidencing the loan
(the "Loan") made to the Transferor Partnership by Washington Capital ("Lender")
and secured by the Loan Documents which shall be an obligation of the Transferor
Partnership as of the Closing subject to any exculpation from liability
provisions therein.

     At the Closing, the BRI Partnership shall pay the amount required to
satisfy the Other Loans, provided that the amount to be paid by the BRI
Partnership shall not exceed the Other Loans BRI Cap. If the amount paid by the
BRI Partnership is not sufficient to pay the Other Loans in full, the Transferor
Partnership shall pay, from funds otherwise allocable under this Agreement to
the Transferor Partners, all



                                      -8-
<PAGE>


additional amounts required to pay off the Other Loans in full. At least fifteen
(15) days prior to the Closing, the Transferor Agent shall deliver a pay-off
letter from each holder of an Other Loan stating the amount required to pay-off
such Other Loan in full, and at Closing, the Transferor shall deliver the
original note evidencing each such Other Loan marked "Paid in Full," or in the
event that the original of any such note is not available, such other evidence
of the satisfaction of such note and release of liability under such Other Loan
as the BRI Partnership may require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or


                                      -9-
<PAGE>


liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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




                                      -10-
<PAGE>


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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

                                    SECTION 3

                                   THE 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

LLP, 60 State Street, Boston, Massachusetts 02109, or such other place as the
Transferor Partnership 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 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 all Transferor Partners 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 Partners. It is agreed that time is of the
essence of this Agreement.

in conflict with or constitute a default under the Transferor Partnership
Agreement or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Transferor Partnership,
except for Permitted Exceptions.

to the



                                      -23-
<PAGE>


sale or distribution of the same or any part thereof in violation of the

Rights Agreement.

     (b) Such Transferor Partner understands that the BRI Partnership Units to
be issued to each Transferor Partner 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 such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons
set forth in Sections 5.35(a) and (b) above, the BRI Partnership Units (or

(and which opinion and counsel shall be reasonably acceptable to both the BRI

registration requirements of the Act and any applicable Blue Sky Laws, and that,
accordingly, such Transferor Partner 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.
Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such that it is able to bear all risks of the

Transferor Agent, its 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



                                      -24-

acquisition of the BRI Partnership Units. Such Transferor Partner further

satisfaction.

     (f) Such Transferor Partner 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

          "The securities represented by this certificate have not been
          registered under the Securities Act of 1933, as amended (the "Act"),

          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 Exhibit I is the address of such Transferor

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

subsequent to the Closing Date, resulting from (A) any inaccuracy in or breach
of any representation or warranty of the Transferor Partnership set forth in
Section 5A or of such Transferor Partner set forth in Section 5B or (B)
resulting from any breach or default by the Transferor Partnership or such

representations of each 



                                      -40-
<PAGE>


of the Transferor Partners in Section 5.34, which shall be limited to 100% of
the fair market value as of the date such indemnification obligation is
satisfied of the BRI Partnership Units received by such Transferor Partner)
(collectively, the "Cap"); and provided further that to the extent any of the
Transferor Partners have any indemnification obligation to the BRI Partnership,
the Transferor Partners may elect to satisfy such indemnification obligation by
directing the BRI Partnership to cancel such amount of BRI Partnership Units
acquired by such Transferor Partner pursuant to this Agreement having a fair
market value (measured at the time such BRI Partnership Units are returned or
cancelled) equal to the indemnification obligation of such Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including

in Section 16. No such claim for indemnification shall be deemed due and 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.



                                      -41-
<PAGE>


     (e) Neither the BRI Partnership nor any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section

Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be

years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,
which shall not be unreasonably withheld or delayed. The BRI Partnership shall

     11.03 Post-Closing Agreements of the BRI Partnership.

satisfaction of the Transferor Partners' distribution rights under Section 8.2

granted by the BRI Partnership to the Transferor Partners.


                                      -44-
<PAGE>


     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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



                                      -45-
<PAGE>


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

     12.01 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

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


                                      -46-
<PAGE>


     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of the Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.




                                      -47-
<PAGE>


     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such 



                                      -48-
<PAGE>


distribution of surplus cash relates only to the period prior to the Closing
Date, all such surplus cash shall be distributed to the Transferor Partners
prior to Closing; provided however, if as a result of the 1997 annual HUD audit
(it being agreed that the BRI Partnership shall consult with the Transferor
Agent during the HUD audit procedure), HUD (after final adjudication by
regulatory and judicial authorities) determines that all or any portion of such
distribution of surplus cash to the Transferor Partners was improper, the
Transferor Partners, severally, agree to reimburse the Transferor Partnership
immediately upon demand for all amounts so designated by HUD as improper and to
indemnify, defend and hold the Transferor Partnership and the BRI Partnership
harmless from and against all loss, cost, damage or expense (including
reasonable legal fees) suffered or incurred as a result of such improper
distribution of surplus cash. In all other cases, there shall be no adjustment
at Closing regarding surplus cash, but at such time as HUD approves the
distribution of surplus cash for fiscal 1997, the BRI Partnership shall receive
all such surplus cash and thereafter the BRI Partnership shall promptly pay to
the Transferor Agent, as distribution agent for the Transferor Partners, the
Transferor Partners pro-rata share of such surplus cash allocable to the period
prior to the Closing Date.


                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor

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

of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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

     14.01 Brokerage Fees. The Transferor Partnership and the BRI Partnership
mutually represent and warrant that neither of them has retained a broker,

commission or fee is owed to APC, it shall be the obligation of the Transferor
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or
transfer fee and other related costs and expenses (not to exceed in the
aggregate 1% of the outstanding principal balance of the Loan) required by
Lender (the "Loan Assumption Fees") in connection with obtaining the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership and the transfer of the ownership of the Transferor Partnership to
the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

                                      -55-
<PAGE>


BRI Partnership and to obtain the Lender Estoppel Letter. The Transferor
Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership and the transfer of
ownership of the Transferor Partnership to the BRI Partnership. The BRI
Partnership shall supply any and all documentation and additional information
required by Lender in order to promptly complete the request for the consent of
Lender to the transactions contemplated hereunder. The Transferor Partnership
shall request that Lender state in writing any terms and requirements, including
the amount of any Loan Assumption Fees, to be imposed by Lender in connection
with its consent to the transactions contemplated hereby. It shall be a
condition of Closing that prior to October 15, 1997, Lender shall have granted
its consent to the transactions contemplated hereunder on terms and requirements
reasonably satisfactory to the BRI Partnership, shall have issued the Lender
Estoppel Letter and shall have agreed to release the Transferor Partners from
all liability under the Loan Documents. In the event that any of the terms or
requirements required by Lender for its consent are not approved by the BRI
Partnership, the BRI Partnership may terminate this Agreement by written notice
given to the Transferor Partners within fifteen (15) business days after the BRI
Partnership have received in writing the terms and requirements of Lender for
its consent. In the event either (a) the consent of Lender is not obtained prior
to the Closing or (b) the BRI Partnership does not approve the terms and
conditions of Lender, including the amount of any Loan Assumption Fees in excess
of 1% of the unpaid principal balance, and the BRI Partnership gives timely
notice of termination hereunder to the Transferor Agent, this Agreement shall
terminate without further action by any party, and, thereafter this Agreement
shall be void and without recourse to all parties, except for provisions which
are expressly stated to survive termination of this Agreement. In the event the
Lender shall not have agreed to release the Transferor Partners from all
liability under the Loan Documents or the Lender shall have placed terms and
conditions on the Transferor Partners that are unacceptable to them, the
Transferor Agent may terminate this Agreement by written notice given to the BRI
Partnership within fifteen (15) business days after the Transferor Agent has
received in writing notice that the Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions. If the Transferor Agent gives timely notice
of termination to the BRI Partnership, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private 



                                      -56-
<PAGE>

placement of common stock or other equity securities of BRI (the "Private
Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI 


                                      -57-
<PAGE>


Partnership will not take possession of the Transferor Partnership or the
Property nor assume the burdens and benefits of project ownership prior to such
approval by HUD.

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives 



                                      -58-
<PAGE>


timely notice of termination hereunder to the Transferor Partners, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall
contribute to the BRI Partnership, and the BRI Partnership shall accept from the

Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in

Immediately thereafter, the Transferor Partners and the BRI Partnership, or its

the partners of the Transferor Partnership and be released of all liability

accordance with the Amended Transferor Partnership Agreement.

     1.02 Property Title. On or before September 5, 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

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
Partnership promptly after its receipt thereof. The Commitment shall insure fee

     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 Partnership on or before September 5, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, to
remove or cure such exceptions, provided further, the Transferor Agent may, but

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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership 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 Partnership 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 Partnership 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.

(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 Partnership promptly after its receipt 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 Partnership on or
before September 5, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and 

                                       -6-

<PAGE>


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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income
                                     

                                       -7-

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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $18,262,099, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing and, minus (Z) the amount required to pay the various outstanding
loans owed by the Transferor Partnership to the Transferor Partners or their
affiliates or to other third-party lenders (the "Other Loans"), but in any
event, the total amount to be deducted under this clause (Z) shall not exceed an
amount equal to the difference between the Consideration Amount minus the
outstanding principal balance of the Note (the "Other Loans BRI Cap").

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated January 10, 1991,
in the original principal amount of $17,938,000 (the "Note") evidencing the loan
(the "Loan") made to the Transferor Partnership by Greystone Servicing
Corporation ("Lender") and secured by the Loan Documents which shall be an
obligation of the Transferor Partnership as of the Closing subject to any
exculpation from liability provisions therein.

At the Closing, the BRI Partnership shall pay the amount required to satisfy the
Other Loans, provided that the amount to be paid by the BRI Partnership shall
not exceed the Other Loans BRI Cap. If the amount paid by the BRI Partnership is
not sufficient to pay the Other Loans in full, the Transferor Partnership shall
pay, from funds otherwise allocable under this Agreement to the Transferor
Partners, all additional amounts 


                                       -8-

<PAGE>



required to pay off the Other Loans in full. At least fifteen (15) days prior to
the Closing, the Transferor Agent shall deliver a pay-off letter from each
holder of an Other Loan stating the amount required to pay-off such Other Loan
in full, and at Closing, the Transferor shall deliver the original note
evidencing each such Other Loan marked "Paid in Full," or in the event that the
original of any such note is not available, such other evidence of the
satisfaction of such note and release of liability under such Other Loan as the
BRI Partnership may require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
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 each Transferor Partner
pursuant to Section 12.04. The Transferor Agent shall be liable to distribute
the BRI Partnership Units and if applicable, a pro-rata share of the BRI
Additional Payment to each of the Transferor Partners in accordance with the
Transferor Allocation Schedule. The BRI Partnership shall have no obligation or



                                       -9-

<PAGE>


liability with respect to the preparation or accuracy of the Preliminary
Transfer Allocation Schedule or the Transferor Allocation Schedule or the
distribution of the BRI Partnership Units or the BRI Additional Payment, if
applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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


                                      -10-

<PAGE>

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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

                                    SECTION 3

                                   THE CLOSING

any event not later than October 31, 1997 the ("Closing Date"). The "Time of

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 all Transferor Partners 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 Partners. It is agreed that time is of the
essence of this Agreement.

     5.35 Investment Representations and Warranties. Each Transferor Partner for
itself, severally and not jointly, represents, warrants, acknowledges and agrees
as follows:

     (a) Such Transferor Partner 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) Such Transferor Partner understands that the BRI Partnership Units to
be issued to each Transferor Partner 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 such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons
set forth in Sections 5.35(a) and (b) above, the BRI Partnership Units (or

Transferor Partner 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

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, such Transferor Partner 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.
Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such 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



                                      -24-

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 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. Such Transferor Partner 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) Such Transferor Partner is an "accredited investor" within the meaning

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) Such Transferor Partner 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


                                      -25-
<PAGE>


          "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, 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 Exhibit I is the address of such Transferor
Partner's principal residence or principal place of business, and such
Transferor Partner has no present intention of becoming a resident of any
country, state or jurisdiction other than the country and state in which such

insurance on the Property which insurance in respect of fire and casualty shall

Closing, each Transferor Partner agrees, severally and not jointly, to indemnify
and hold the BRI Partnership harmless against and with respect to (i) any loss
or damage (including reasonable attorney's fees) to the BRI Partnership
subsequent to the Closing Date, resulting from (A) any inaccuracy in or breach
of any representation or warranty of the Transferor Partnership set forth in
Section 5A or of such Transferor Partner set forth in Section 5B or (B)
resulting from any breach or default by the Transferor Partnership or such
Transferor Partner of any obligation of the Transferor Partnership or such

representations of each




                                      -40-
<PAGE>


of the Transferor Partners in Section 5.34, which shall be limited to 100% of
the fair market value as of the date such indemnification obligation is
satisfied of the BRI Partnership Units received by such Transferor Partner)
(collectively, the "Cap"); and provided further that to the extent any of the
Transferor Partners have any indemnification obligation to the BRI Partnership,
the Transferor Partners may elect to satisfy such indemnification obligation by
directing the BRI Partnership to cancel such amount of BRI Partnership Units
acquired by such Transferor Partner pursuant to this Agreement having a fair
market value (measured at the time such BRI Partnership Units are returned or
cancelled) equal to the indemnification obligation of such Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including

Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any

satisfied of the BRI Partnership Units received by such Transferor Partner
(except for indemnification obligations with respect to Sections 6.10 and 11.03
which shall be limited to 100% of the fair market value as of the date such
indemnification obligation is satisfied of the BRI Partnership Units received by

Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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.



                                      -41-
<PAGE>


     (e) Neither the BRI Partnership nor any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

Partnership shall terminate for federal income tax purposes pursuant to Section

Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be

years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,
which shall not be unreasonably withheld or delayed. The BRI Partnership shall

Transferor Agent to permit the Transferor Partnership to prepare such returns or

satisfaction of the Transferor Partners' distribution rights under Section 8.2

granted by the BRI Partnership to the Transferor Partners.


                                      -44-
<PAGE>


     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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



                                      -45-
<PAGE>


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

     12.01 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

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


                                      -46-
<PAGE>


     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of the Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.


                                      -47-
<PAGE>


     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such



                                      -48-
<PAGE>


distribution of surplus cash relates only to the period prior to the Closing
Date, all such surplus cash shall be distributed to the Transferor Partners
prior to Closing; provided however, if as a result of the 1997 annual HUD audit
(it being agreed that the BRI Partnership shall consult with the Transferor
Agent during the HUD audit procedure), HUD (after final adjudication by
regulatory and judicial authorities) determines that all or any portion of such
distribution of surplus cash to the Transferor Partners was improper, the
Transferor Partners, severally, agree to reimburse the Transferor Partnership
immediately upon demand for all amounts so designated by HUD as improper and to
indemnify, defend and hold the Transferor Partnership and the BRI Partnership
harmless from and against all loss, cost, damage or expense (including
reasonable legal fees) suffered or incurred as a result of such improper
distribution of surplus cash. In all other cases, there shall be no adjustment
at Closing regarding surplus cash, but at such time as HUD approves the
distribution of surplus cash for fiscal 1997, the BRI Partnership shall receive
all such surplus cash and thereafter the BRI Partnership shall promptly pay to
the Transferor Agent, as distribution agent for the Transferor Partners, the
Transferor Partners pro-rata share of such surplus cash allocable to the period
prior to the Closing Date.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners shall be in
default under this Agreement and the BRI Partnership shall be entitled to
terminate this Agreement by written notice 



                                      -49-
<PAGE>


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 Transferor
Partnership Interests in accordance with the terms of this Agreement and the
Transferor Partners willfully refuse to perform the Transferor Partners'
obligations hereunder, the BRI Partnership, at its option, shall have the right
to compel specific performance by the Transferor Partners hereunder, in which
event the BRI Partnership shall have the right to recover from the Transferor
Partners 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 Partners in lieu
of all other rights and remedies which the BRI Partnership may have against the
Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.

                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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 Partnership 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
Partners 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 or the Transferor Partnership have any obligation to pay any

                                      -55-
<PAGE>


BRI Partnership and to obtain the Lender Estoppel Letter. The Transferor
Partnership, with the BRI Partnership's cooperation, shall immediately commence
to obtain the consent of Lender necessary to permit the contribution of the
Transferor Partnership Interests to the BRI Partnership and the transfer of
ownership of the Transferor Partnership to the BRI Partnership. The BRI
Partnership shall supply any and all documentation and additional information
required by Lender in order to promptly complete the request for the consent of
Lender to the transactions contemplated hereunder. The Transferor Partnership
shall request that Lender state in writing any terms and requirements, including
the amount of any Loan Assumption Fees, to be imposed by Lender in connection
with its consent to the transactions contemplated hereby. It shall be a
condition of Closing that prior to October 15, 1997, Lender shall have granted
its consent to the transactions contemplated hereunder on terms and requirements
reasonably satisfactory to the BRI Partnership, shall have issued the Lender
Estoppel Letter and shall have agreed to release the Transferor Partners from
all liability under the Loan Documents. In the event that any of the terms or
requirements required by Lender for its consent are not approved by the BRI
Partnership, the BRI Partnership may terminate this Agreement by written notice
given to the Transferor Partners within fifteen (15) business days after the BRI
Partnership have received in writing the terms and requirements of Lender for
its consent. In the event either (a) the consent of Lender is not obtained prior
to the Closing or (b) the BRI Partnership does not approve the terms and
conditions of Lender, including the amount of any Loan Assumption Fees in excess
of 1% of the unpaid principal balance, and the BRI Partnership gives timely
notice of termination hereunder to the Transferor Agent, this Agreement shall
terminate without further action by any party, and, thereafter this Agreement
shall be void and without recourse to all parties, except for provisions which
are expressly stated to survive termination of this Agreement. In the event the

liability under the Loan Documents or the Lender shall have placed terms and
conditions on the Transferor Partners that are unacceptable to them, the
Transferor Agent may terminate this Agreement by written notice given to the BRI
Partnership within fifteen (15) business days after the Transferor Agent has
received in writing notice that the Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions. If the Transferor Agent gives timely notice
of termination to the BRI Partnership, this Agreement shall terminate without
further action by any party, and, thereafter this Agreement shall be void and
without recourse to all parties, except for provisions which are expressly
stated to survive termination of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private 



                                      -56-
<PAGE>


placement of common stock or other equity securities of BRI (the "Private
Placement"). The Transferor Partners shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement. The
obligation of the BRI Partnership to proceed with the Closing of the
transactions contemplated by this Agreement is expressly conditioned upon the
successful completion of the Public Offering and the Private Placement raising a
minimum of $75,000,000.00. If the Public Placement and the Private Placement do
not in the aggregate complete offerings which raise a minimum of $75,000,000 as
aforesaid prior to the Closing Date hereunder, the BRI Partnership shall have
the right to terminate this Agreement effective as of the Closing Date, and,
thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI 



                                      -57-
<PAGE>


Partnership will not take possession of the Transferor Partnership or the
Property nor assume the burdens and benefits of project ownership prior to such
approval by HUD.

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives 



                                      -58-
<PAGE>


timely notice of termination hereunder to the Transferor Partners, this
Agreement shall terminate without further action by any party, and, thereafter
this Agreement shall be void and without recourse to all parties, except for
provisions which are expressly stated to survive termination of this Agreement.

authorized to determine the allocations of the transaction costs and expenses to
be allocated in accordance with the provisions of this Section 19.03.

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

     1.01 Agreement to Contribute; Assignment. The Transferor Partners shall

Partnership Interests to the BRI Partnership, or its designees as provided in
Section 18.01 hereof, by an Assignment and Assumption of Partnership Interest in

the partners of the Transferor Partnership and be released of all liability

accordance with the Amended Transferor Partnership Agreement.

     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

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
Partnership promptly after its receipt thereof. The Commitment shall insure fee

     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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, to

"Monetary Liens") shall automatically be deemed to be unacceptable exceptions to
title and shall be paid and removed by the Transferor Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership 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 Partnership 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 Partnership 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.

Transferor Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable survey
matters. If the Transferor Partnership 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 Partnership notifies

and (B) Closing Date, the BRI Partnership may, in accordance with the provisions

     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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's books, financial records, Service
Contracts, Leases and


                                      -6-
<PAGE>

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 Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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 Partners 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 Partners
hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners to the BRI
Partnership in accordance with Section 1.01 of this Agreement be treated for
federal (and applicable state) income 


                                      -7-
<PAGE>

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 Partners
agree to report such transaction for federal and applicable state income tax
purposes consistently with the intent set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS

     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $13,224,828, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined), as
of the Closing and minus (Z) the amount required to pay both (i) the
Subordinated Promissory Note dated May 14, 1993 (the "Subordinated Note") from
the Transferor Partnership to Krupp Government Income Trust (the "Subordinated
Lender") evidencing a loan made to the Transferor Partnership (the "Subordinated
Loan"), secured by the relevant Loan Documents, and (ii) the various outstanding
loans owed by the Transferor Partnership to the Transferor Partners or their
affiliates or to other third-party lenders (the "Other Loans"; such term shall
include, without limitation, the Subordinated Loan), but in any event, the total
amount to be deducted under this clause (Z) shall not exceed an amount equal to
the difference between the Consideration Amount minus the outstanding principal
balance of the Note (the "Other Loans BRI Cap").

     In addition, as of Closing, the Transferor Partnership shall remain as
obligor of the outstanding principal balance of the Note dated May 14, 1993, in
the original principal amount of $12,000,000 (the "Note") evidencing the loan
(the "Loan") made to the Transferor Partnership by CPC Mortgage Capital, LLC
("Lender") and secured by the relevant Loan Documents which shall be an
obligation of the Transferor Partnership as of the Closing subject to any
exculpation from liability provisions therein.


                                      -8-
<PAGE>

     At the Closing, the BRI Partnership shall pay the amount required to
satisfy the Other Loans, including the Subordinated Loan, provided that the
amount to be paid by the BRI Partnership shall not exceed the Other Loans BRI
Cap. If the amount paid by the BRI Partnership is not sufficient to pay the
Other Loans, including the Subordinated Loan, in full, the Transferor
Partnership shall pay, from funds otherwise allocable under this Agreement to
the Transferor Partners, all additional amounts required to pay off the Other
Loans, including the Subordinated Loan, in full. At least fifteen (15) days
prior to the Closing, the Transferor Agent shall deliver a pay-off letter from
each holder of an Other Loan stating the amount required to pay-off such Other
Loan in full, and at Closing, the Transferor shall deliver the original note
evidencing each such Other Loan marked "Paid in Full," or in the event that the
original of any such note is not available, such other evidence of the
satisfaction of such note and release of liability under such Other Loan as the
BRI Partnership may require.

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule (as defined in Section 12.01)
shall be prepared by the Transferor Agent based upon the Preliminary Transferor
Allocation Schedule and shall be delivered to the BRI Partnership prior to
Closing in accordance with the provisions of Section 12.01 hereof, together with
an investor questionnaire in the form attached hereto as Exhibit 5 (the "BRI
Questionnaire") for each Transferor Partner. In the event that any Transferor
Partner 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 all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Partners
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Partners
as a result of prorations and apportionments 


                                      -9-
<PAGE>

(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 each Transferor Partner pursuant to Section 12.04. The Transferor Agent
shall be liable to distribute the BRI Partnership Units and if applicable, a
pro-rata share of the BRI Additional Payment to each of the Transferor Partners
in accordance with the Transferor Allocation Schedule. The BRI Partnership shall
have no obligation or liability with respect to the preparation or accuracy of
the Preliminary Transfer Allocation Schedule or the Transferor Allocation
Schedule or the distribution of the BRI Partnership Units or the BRI Additional
Payment, if applicable, to the Transferor Partners and the Transferor Partners
hereby release the BRI Partnership from any such obligation or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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 transfer.

     2.03 Reimbursement of Escrow. At the Closing, the BRI Partnership shall
replace the escrow deposits set forth on Schedule C attached hereto in the
amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

<PAGE>

     (a) Such Transferor Partner 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

be issued to each Transferor Partner 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

predicated in part on the accuracy and completeness of the representations and
warranties of such Transferor Partner.

     (c) Such Transferor Partner acknowledges and agrees that, for the reasons

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.
Such Transferor Partner acknowledges, represents and agrees that (i) its
economic circumstances are such that it is able to bear all risks of the

its management concerning its investment in the BRI Partnership and the
transactions contemplated hereby, which questions were answered to its
satisfaction.

     (f) Such Transferor Partner 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

               will be exempt from registration under the Act and its applicable
               state securities laws"; and

the Transferor Partnership shall be entitled to rely on the agreements contained
in this Section 10.03.

     10.04 Post-Closing Restrictions on the Transferor Partners. In order to
induce the BRI Partnership to enter into this Agreement, each Transferor
Partner, hereby agrees that until the tenth (10th) day following the first
anniversary of the Closing:

     (a) each Transferor Partner shall continue to own and hold, and shall not
assign, transfer, distribute to its partners or otherwise dispose of any of the
BRI Partnership Units received by it pursuant to this Agreement except to the
extent permitted under Section 9 of the BRI Partnership Agreement;

     (b) no Transferor Partner shall transfer or exchange the BRI Partnership
Units for shares of common stock of BRI;

     (c) except for the pledge of BRI Partnership Units by Morton Gorn, Stephen

Transferor Partner shall mortgage, pledge, create a security interest in or lien
on or otherwise hypothecate or encumber any of such BRI Partnership Units except
as permitted under the BRI Partnership Agreement;

     (d) the provisions of this Section 10.03 shall survive the Closing
indefinitely.

     10.05 Indemnification.

     (a) The Transferor Partners' Indemnity. In the event the parties proceed to
Closing, each Transferor Partner agrees, severally and not jointly, to indemnify
and hold the BRI Partnership harmless against and with respect to (i) any loss
or damage (including reasonable attorney's fees) to the BRI Partnership
subsequent to the Closing Date, resulting from (A) any inaccuracy in or breach
of any representation or warranty of the Transferor Partnership set forth in
Section 5A or of such Transferor Partner set forth in Section 5B or (B)
resulting from any breach or default by the Transferor Partnership or such
Transferor Partner of any obligation of the Transferor Partnership or such
Transferor Partner under this Agreement or (ii) from liabilities for borrowed
money (other than the payments under the Loan due after the Closing) incurred by
the Transferor Partnership or the Property prior to the Closing; provided that
no Transferor Partner shall be required to indemnify the BRI Partnership for any
amounts in excess of 50% of the fair market value of the BRI Partnership Units
received by such Transferor Partner as of the date such indemnification
obligation is satisfied (except for indemnification obligations with respect to
representations of each 


                                      -40-
<PAGE>

of the Transferor Partners in Section 5.34, which shall be limited to 100% of
the fair market value as of the date such indemnification obligation is
satisfied of the BRI Partnership Units received by such Transferor Partner)
(collectively, the "Cap"); and provided further that to the extent any of the
Transferor Partners have any indemnification obligation to the BRI Partnership,
the Transferor Partners may elect to satisfy such indemnification obligation by
directing the BRI Partnership to cancel such amount of BRI Partnership Units
acquired by such Transferor Partner pursuant to this Agreement having a fair
market value (measured at the time such BRI Partnership Units are returned or
cancelled) equal to the indemnification obligation of such Transferor Partner.

     (b) The BRI Partnership's Indemnity. In the event the parties proceed to
Closing, the BRI Partnership agrees to indemnify and hold the Transferor
Partners harmless against and with respect to (i) any loss or damage (including
reasonable attorney's fees) to the Transferor Partners, subsequent to the
Closing Date, resulting from (A) any inaccuracy in or breach of any
representation or warranty of the BRI Partnership or (B) resulting from any
breach or default by the BRI Partnership of any obligation of the BRI
Partnership under this Agreement or (ii) from liabilities of the Transferor
Partnership or the Property after the Closing (except for such liabilities
resulting from a breach or default by the Transferor Partners or the Transferor
Partnership for which the BRI Partnership is indemnified under Section 10.05(a)
above); provided that the BRI Partnership shall not be required to indemnify any
Transferor Partner under Section 10.05(b)(i) for any amounts in excess of 50% of
the fair market value as of the date such indemnification obligation is
satisfied of the BRI Partnership Units received by such Transferor Partner
(except for indemnification obligations with respect to Sections 6.10 and 11.03
which shall be limited to 100% of the fair market value as of the date such
indemnification obligation is satisfied of the BRI Partnership Units received by
such Transferor Partner).

     (c) The indemnification obligations of the Transfer Partners and the BRI
Partnership, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 16. No such claim for indemnification shall be deemed due and 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.


                                      -41-
<PAGE>

     (e) Neither the BRI Partnership nor any of the Transferor Partners 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 Partners 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 Partnership or the Property.

     (g) Each of the Transferor Partners, the Transferor Partnership 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.

     10.06 Post-Closing Tax Matters. As a result of the Closing, the Transferor
Partnership shall terminate for federal income tax purposes pursuant to Section
708(b)(1)(B) of the Code and its tax year shall close on the Closing Date. The
Transferor Agent shall prepare and timely file any federal, state, local and
foreign tax or information returns due after Closing that are required to be
filed by or on behalf of the Transferor Partnership with respect to all tax
years or periods ending on or prior to the Closing Date. The Transferor Agent
shall prepare and timely file the terminating tax returns for the Transferor
Partnership resulting from the consummation of the transactions contemplated
under this Agreement, provided, however, that such tax returns shall be prepared
in accordance with the terms and provisions of this Agreement and provided
further, that prior to the filing thereof the Transferor Agent shall submit the
terminating tax returns to the BRI Partnership for its review and approval,
which shall not be unreasonably withheld or delayed. The BRI Partnership shall
assist the Transferor Agent in obtaining such data and information regarding the
Transferor Agent to permit the Transferor Partnership to prepare such returns or
to respond to any audits or assessments for the periods covered by such returns.

     11.03 Post-Closing Agreements of the BRI Partnership.

satisfaction of the Transferor Partners' distribution rights under Section 8.2
of the BRI Partnership Agreement. If the Transferor Partnership Interests are
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 Partners.


                                      -44-
<PAGE>

     (b) Until the expiration of the period (the "No Transfer Period") ending on
the earlier of (I) such time as all of the Transferor Partners have redeemed all
of the BRI Partnership Units received by the Transferor Partners 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
either the Transferor Partnership Interests or 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) Until the expiration of the No Transfer Period, neither the BRI
Partnership nor BRI shall allow the Transferor Partnership to refinance the Loan
for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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


                                      -45-
<PAGE>

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

     12.01 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

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


                                      -46-
<PAGE>

     (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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transfer Allocation Schedule (the "Transfer Allocation Schedule"), which shall
be based upon the Preliminary Transfer Allocation Schedule, shall incorporate
all adjustments and prorations to be made pursuant to Section 12 and shall set
forth (i) the name of each Transferor Partner, (ii) the number of Unrestricted
Distribution BRI Partnership Units to be received by each Transferor Partner,
and (iii) the number of the Restricted Distribution BRI Partnership Units to be
received by each Transferor Partner. The BRI Partnership shall have no
obligation or liability with respect to the preparation or accuracy of the
Preliminary Transferor Allocation Schedule or the Transfer Allocation Schedule
or the distribution of the BRI Partnership Units or the BRI Additional Payment,
if applicable, to the Transferor Partners and the Transferor Partners hereby
release the BRI Partnership from any such obligation or liability.

     All cash (including the escrow deposits set forth on Schedule C) shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to Closing, and
if any of such cash applicable to pre-closing periods is not removed from the
Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to 


                                      -47-
<PAGE>

receive such rent to the Transferor Partners immediately prior to Closing. The
BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

     12.05 Surplus Cash. No surplus cash shall be distributed from the
Transferor Partnership after the date of this Agreement unless the amount of
such surplus cash has been established in accordance with the Regulatory
Agreement. If (a) there shall be no outstanding unresolved HUD audit
investigation relating to the Property and (b) such distribution of surplus cash
relates only to the period prior to the Closing Date, all such surplus cash
shall be distributed to the Transferor Partners prior to Closing; provided

                                      -48-
<PAGE>

however, if as a result of the 1997 annual HUD audit (it being agreed that the
BRI Partnership shall consult with the Transferor Agent during the HUD audit
procedure), HUD (after final adjudication by regulatory and judicial
authorities) determines that all or any portion of such distribution of surplus
cash to the Transferor Partners was improper, the Transferor Partners,
severally, agree to reimburse the Transferor Partnership immediately upon demand
for all amounts so designated by HUD as improper and to indemnify, defend and
hold the Transferor Partnership and the BRI Partnership harmless from and
against all loss, cost, damage or expense (including reasonable legal fees)
suffered or incurred as a result of such improper distribution of surplus cash.
In all other cases, there shall be no adjustment at Closing regarding surplus
cash, but at such time as HUD approves the distribution of surplus cash for
fiscal 1997, the BRI Partnership shall receive all such surplus cash and
thereafter the BRI Partnership shall promptly pay to the Transferor Agent, as
distribution agent for the Transferor Partners, the Transferor Partners pro-rata
share of such surplus cash allocable to the period prior to the Closing Date.

                                   SECTION 13

                               FAILURE TO PERFORM

     13.01 Defective Title or Condition. If the Transferor Partners are unable
to give title or to contribute and transfer the Transferor Partnership
Interests, or to deliver possession of the Property, or to satisfy all of the
terms and conditions precedent to closing as set forth in this Agreement, all as
herein stipulated, or if on the scheduled closing the Transferor Partnership
Interests or 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 Partners can deliver to the Transferor Partnership Interests and 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 Partners' Default. If on the Closing Date, the Transferor
Partners have failed to perform all of the material obligations of the
Transferor Partners under this Agreement, the Transferor Partners 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


                                      -49-
<PAGE>

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 Transferor Partnership Interests in
accordance with the terms of this Agreement and the Transferor Partners
willfully refuse to perform the Transferor Partners' obligations hereunder, the
BRI Partnership, at its option, shall have the right to compel specific
performance by the Transferor Partners hereunder, in which event the BRI
Partnership shall have the right to recover from the Transferor Partners 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 Partners in lieu of all other rights and
remedies which the BRI Partnership may have against the Transferor Partners 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
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 all
of the Transferor Partners desire 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 Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against
the BRI Partnership at law or in equity.


                                   SECTION 14

                       BROKERAGE AND LOAN ASSUMPTION FEES

     14.01 Brokerage Fees. The Transferor Partnership 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


                                      -50-
<PAGE>

connection with this transaction. The Transferor Partnership 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 Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

     14.02 Loan Assumption Fees. The BRI Partnership will pay any assumption or

Transferor Partnership shall use reasonable efforts to obtain the consent of
Lender to the contribution of the Transferor Partnership Interests to the BRI
Partnership by the Transferor Partners, to the transfer of ownership of the
Transferor Partnership to the BRI Partnership and to obtain the Lender Estoppel
Letter. The Transferor Partnership, with the BRI Partnership's cooperation,
shall immediately commence to obtain the consent of Lender necessary to permit
the contribution of the Transferor Partnership Interests to the BRI Partnership
and the transfer of ownership of the Transferor Partnership to the BRI
Partnership. The BRI Partnership shall supply any and all documentation and

and requirements, including the amount of any Loan Assumption Fees, to be

terms and requirements reasonably satisfactory to the BRI Partnership, shall
have issued the Lender Estoppel Letter and shall have agreed to release the
Transferor Partners from all


                                      -55-

Additional Interest, Shared Income Interest, and Shared Appreciation Features of
the Subordinated Note, as such terms are defined in the Subordinated Note, on
terms and conditions satisfactory to the Transferor Partnership and the BRI
Partnership. In the event that any of the terms or requirements required by
Lender or the Subordinated Lender for their respective consents or agreements
are not approved by the BRI Partnership, the BRI Partnership may terminate this
Agreement by written notice given to the Transferor Partners within fifteen (15)
business days after the BRI Partnership have received in writing the terms and

Partnership does not approve the terms and conditions of Lender and the
Subordinated Lender, including the amount of any Loan Assumption Fees in excess

notice of termination hereunder to the Transferor Agent, this Agreement shall
terminate without further action by any party, and, thereafter this Agreement
shall be void and without recourse to all parties, except for provisions which
are expressly stated to survive termination of this Agreement. In the event the
Lender or the Subordinated Lender shall not have agreed to release the
Transferor Partners from all liability under the applicable Loan Documents or
the Lender or the Subordinated Lender shall have placed terms and conditions on
the Transferor Partners that are unacceptable to them or the Subordinated Lender
shall not have agreed to the pay-off of the Subordinated Note on terms
acceptable to the Transferor Partnership, the Transferor Agent may terminate
this Agreement by written notice given to the BRI Partnership within fifteen
(15) business days after the Transferor Agent has received in writing notice
that the Lender or the Subordinated Lender has refused to release the Transferor
Partners from liability under the Loan Documents or has imposed such
unacceptable terms and conditions or that the Subordinated Lender has not agreed
to the pay-off of the Subordinated Note described above on such acceptable
terms. If the Transferor Agent gives timely notice of termination to the BRI
Partnership, this Agreement shall terminate without further action by any party,
and, thereafter this Agreement shall be void and without recourse to all
parties, except for provisions which are expressly stated to survive termination
of this Agreement.

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private placement of common stock or other equity
securities of BRI (the "Private Placement"). The Transferor Partners shall
supply any documentation and additional information 


                                      -56-
<PAGE>

required by BRI in order to complete the offering materials in connection with
the Public Offering or the Private Placement. The obligation of the BRI
Partnership to proceed with the Closing of the transactions contemplated by this
Agreement is expressly conditioned upon the successful completion of the Public
Offering and the Private Placement raising a minimum of $75,000,000.00. If the
Public Placement and the Private Placement do not in the aggregate complete
offerings which raise a minimum of $75,000,000 as aforesaid prior to the Closing
Date hereunder, the BRI Partnership shall have the right to terminate this
Agreement effective as of the Closing Date, and, thereafter this Agreement 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 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.

     17.06 TPA Approval. This Agreement is subject to the following HUD Required
Language: This Agreement is expressly conditioned upon preliminary approval by
HUD of the transactions as set forth in form HUD 92266, Application for Transfer
of Physical Assets, and supporting documents submitted to HUD. None of the terms
and conditions of this Agreement shall be effective prior to such HUD approval.
The BRI Partnership will not take possession of the Transferor Partnership or
the Property nor assume the burdens and benefits of project ownership prior to
such approval by HUD.


                                      -57-
<PAGE>

     The Transferor Partnership shall file with the appropriate Area Office of
HUD an Application (the "Application") for Transfer of Physical Assets ("TPA
Approval"). The BRI Partnership and the Transferor Partnership shall use
reasonable efforts to obtain the TPA Approval from HUD. The BRI Partnership
shall supply any and all documentation and additional information required by
HUD in order to properly complete the Application. In the event that the Lender
must join in and execute the Application, the Transferor Partnership shall be
responsible to obtain the execution of the Application by Lender.

     In the event that any special conditions are set forth in the preliminary
HUD TPA Approval or required by the Lender relating to the transfer of ownership
of the Transferor Partnership to the BRI Partnership and satisfaction of the
same is reasonably and verifiably estimated by the BRI Partnership to involve an
aggregate cost to the Transferor Partners of not more than $5,000.00, the
Transferor Partners shall be obligated to proceed with the Closing and the BRI
Partnership shall receive a credit equal to the estimated aggregate cost to
comply with said special conditions up to a maximum of $5,000.00. If the cost,
as estimated by the BRI Partnership, to comply with the special conditions
exceeds $5,000.00, the BRI Partnership shall have the option either to terminate
this Agreement or to proceed with the Closing under this Agreement and to fund
all amounts necessary to comply said special conditions in excess of $5,000.00
(in which event the BRI Partnership shall receive a credit against the BRI
Additional Payment in the sum of $5,000.00 from the Transferor Partners).

     One half (1/2) of any fees payable to HUD arising out of the Application
shall be paid by the Transferor Partners and one half (1/2) of any such fees
shall be paid by the BRI Partnership. In addition to the foregoing, the legal
fees of counsel retained by the Transferor Partnership to assist in obtaining
the TPA Approval shall be paid by the Transferor Partners (collectively "HUD TPA
Application Costs").

     It shall be a condition of Closing that prior to Closing, HUD shall have
granted the TPA Approval to the transactions contemplated hereunder on terms and
requirements reasonably satisfactory to the BRI Partnership. In the event that
any of the terms or requirements required by HUD for the issuance of the TPA
Approval are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership has received in
writing the terms and requirements of HUD for the issuance of the TPA Approval.
In the event either (a) the consent of HUD to issue the TPA Approval is not
obtained prior to the Closing or (b) the BRI Partnership does not approve the
terms and conditions of HUD and gives timely notice of termination hereunder to
the Transferor Partners, this Agreement shall terminate without further action
by any party, and, thereafter this Agreement shall 


                                      -58-
<PAGE>

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

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. Each of the Transferor

allocated based on the pro rata number of BRI Partnership Units allocated to
each of them with respect to their interest in the Transferor Partnership and

and the Related Entities at Closing based on the pro rata number of BRI
Partnership Units allocated at Closing to each of them. Each of the Transferor

authorized to determine the allocations of the transaction costs and expenses to
be allocated in accordance with the provisions of this Section 19.03.

                                    SECTION 1

                   CONTRIBUTION OF INTEREST AND DUE DILIGENCE

<PAGE>



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
Partnership promptly after its receipt thereof. The Commitment shall insure fee
simple title to the Property in the sole name of the Transferor 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

     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 Partnership on or before August 31, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Partnership 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 Partnership
in writing of such fact as above provided, the Transferor Partnership shall have
thirty (30) days from the date the Transferor Partnership receives notice of
such unacceptable exceptions, at the option of the Transferor Partnership, 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 the Loan Documents and 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 Partners at Closing. The
Transferor Partnership shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Partnership, within ten (10) days after receipt
of notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to cure such unacceptable
exceptions. If the Transferor Partnership fails or refuses to cure said
unacceptable exceptions within the time period above provided, on or before the
earlier to occur of

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 Partnership
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

(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 Partnership promptly after its receipt 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 Partnership on or
before August 31, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Partnership 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
Partnership in writing of such fact as above provided, the Transferor
Partnership shall have thirty (30) days from the date the Transferor Partnership
receives notice of such unacceptable survey matters, at the option of the
Transferor Partnership, to cure such unacceptable survey matters. The Transferor
Partnership shall be deemed to have refused to cure any unacceptable survey
matters unless the Transferor Partnership, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Partnership will attempt to 



                                       -5-

<PAGE>



cure such unacceptable survey matters. If the Transferor Partnership 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 Partnership 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 Partnership 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 August 31,
1997 (the "Due Diligence Period") during regular business hours and on
reasonable prior notice to the Transferor Partnership, inspect the Property to
determine the presence of any Hazardous Materials (as defined in Section 5.21)
and the compliance of the Property 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 Partnership 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
Partnership 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
Partnership 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 



                                       -6-

<PAGE>



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 Partnership
shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Partnership's and the Borrower Partnership'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 Partnership's
or the Borrower Partnership's financial records relating to the Property have
been audited, the Transferor Partnership agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Partnership shall provide
the BRI Partnership with such information as the Transferor Partnership 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 Partnership, 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 Partnership if the Closing does
not occur.

     (d) The BRI Partnership shall indemnify the Transferor Partners 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 Partners 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 Partners 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 Partners
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



                                       -7-

<PAGE>



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 Partners 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 Partners hereunder.

     1.05 Tax Treatment. The parties intend that the contribution of the
Transferor Partnership Interests by the Transferor Partners 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 Partners agree to report such transaction for
federal and applicable state income tax purposes consistently with the intent
set forth in this Section 1.05.

                                    SECTION 2

                         CONSIDERATION, ACCEPTABLE FUNDS
                               AND ESCROW DEPOSITS


     2.01 Consideration; Partnership Units.

     (a) The Transferor Partners 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 Transferor Partnership
Interests by the Transferor Partners to the BRI Partnership pursuant to this
Agreement shall be the total of a number of BRI Partnership Units, to be issued
by the BRI Partnership to the Transferor Partners 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) $7,030,019, subject to the prorations and
adjustments as provided in this Agreement, (the "Consideration Amount") minus
(Y) the outstanding principal balance of the Note (as hereinafter defined) as of
the Closing.

     In addition, as of Closing, the Transferor Partnership shall remain as
Guarantor under a certain Guaranty (the "Guaranty") in favor of The Patrician
Financial Company ("Lender"), securing the outstanding principal balance of the
Note dated October 29, 1996, in the original principal amount of $5,100,000 (the
"Note") evidencing the loan (the "Loan") made to the Borrower Partnership by
Lender. The Loan is also secured by the other Loan Documents (as defined in
Section 5.20 hereof) which shall be an obligation of the Borrower Partnership
and the Transferor Partnership as of the Closing subject to any exculpation from
liability provisions therein. The Transferor Partnership shall also remain as
obligor of the outstanding principal balance of the note dated October 29,



                                       -8-

<PAGE>



1996 in the original principal amount of the Note (the "Borrower Partnership
Note"), evidencing the loan made to the Transferor Partnership by the Borrower
Partnership (the "Borrower Partnership Loan").

     At Closing, certain of the Transferor Partners listed on the Transferor
Allocation Schedule (hereinafter defined) will receive BRI Partnership Units
which shall not be entitled to distributions for a one-year period from the date
of issuance (the "Restricted Distribution BRI Partnership Units") and all other
Transferor Partners will receive BRI Partnership Units which shall be entitled
to distributions effective from date of issuance (the "Unrestricted Distribution
BRI Partnership Units"). Unless expressly stated to the contrary herein, the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units are collectively referred to herein as the "BRI
Partnership Units."

     Attached hereto as Exhibit I is a schedule (the "Preliminary Transferor
Allocation Schedule") prepared by the Transferor Agent setting forth (i) the
name of each Transferor Partner, (ii) the percentage interest of each Transferor
Partner, (iii) the identity of each Transferor Partner who will receive
Unrestricted Distribution BRI Partnership Units and (iv) the identity of each
Transferor Partner who will receive Restricted Distribution BRI Partnership
Units. The final Transferor Allocation Schedule shall be prepared by the
Transferor Agent based upon the Preliminary Transferor Allocation Schedule and
shall be delivered to the BRI Partnership prior to Closing in accordance with
the provisions of Section 12.01 hereof, together with an investor questionnaire
in the form attached hereto as Exhibit 5 (the "BRI Questionnaire") for each
Transferor Partner. In the event that any Transferor Partner 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 all
of the BRI Partnership Confirmations evidencing the issuance of the BRI
Partnership Units to the Transferor Partners in accordance with the Transferor
Allocation Schedule. In addition, if pursuant to Section 12, the BRI Partnership
owes any amounts to the Transferor Partners 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 each Transferor Partner pursuant to Section 12.04. The
Transferor Agent shall be liable to distribute the BRI Partnership Units and if
applicable, a pro-rata share of the BRI Additional Payment to each of the
Transferor Partners in accordance with the Transferor Allocation Schedule. The
BRI Partnership shall have no obligation or liability with respect to the
preparation or accuracy of the Preliminary Transferor Allocation Schedule or the
Transferor Allocation Schedule or the distribution of the BRI Partnership Units
or the BRI Additional Payment, if applicable, to the Transferor Partners and the
Transferor Partners hereby release the BRI Partnership from any such obligation
or liability.

     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 and for purposes of this Agreement shall include the
Unrestricted Distribution BRI Partnership Units and the Restricted Distribution
BRI Partnership Units. At the time that any Transferor Partner 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. Each Transferor Partner 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 Partners 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 Partners a certified copy of the
Registration Rights Agreement.

     (c) The Transferor Partners, acknowledge and agree 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 Partners 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.

amounts and to the parties set forth on Schedule C in accordance with wire
instructions provided by the Transferor Agent.

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

Transferor Partnership is not in violation of any order, statute, rule or
regulation applicable to it, except for such violations which would not have a
Material Adverse Effect. Neither the execution, delivery and performance of this

satisfaction.

     (f) Such Transferor Partner acknowledges and agrees that:

good standing under the laws of the State of Maryland. The Borrower Partnership
has all requisite power to maintain the Loan from Lender and to maintain the
Borrower Partnership Loan to the Transferor Partnership and to carry on its

<PAGE>



knowledge the Borrower Partnership is not in violation of any order, statute,
rule or regulation applicable to it, except for such violations which would not
have a Material Adverse Effect. Neither the execution, delivery and performance
of this Agreement by the Transferor Partnership, nor the contribution of the
Transferor Partnership Interests by the Transferor Partners hereunder, nor the
assignment and transfer of the Borrower General Partnership Interest by the
Borrower Corporate General Partner to the Borrower LLC General Partner will
result in any Material Adverse Effect or be in conflict with or constitute a
default under the Borrower Partnership Agreement or result in the creation of
any mortgage, pledge, lien, encumbrance or charge upon any of the properties or
assets of the Borrower Partnership.

     5.39 Partnership Capitalization. The Borrower Partnership Agreement (i) is
the only agreement among the partners thereto relating to the organization,

partner of the Borrower Partnership is in default with respect to any capital
contribution required to be paid by it pursuant to the Borrower Partnership
Agreement. A true, correct and complete copy of the Borrower Partnership
Agreement is attached hereto as Exhibit IX. The Borrower Partnership has no
commitment to issue any right to purchase or acquire or to issue or distribute
to the partners thereof any evidences of indebtedness or assets; and the
Borrower Partnership has no obligation, contingent or otherwise, to purchase,
redeem or otherwise acquire any interest in the Borrower Partnership or any
interest therein or to make any distribution in respect thereof.

     5.40 Agreements; Affiliated and Extraordinary Transactions. Other than the
Loan Documents and the Borrower Partnership Note, there are no agreements, oral

entered into on behalf of the Borrower Partnership.

     5.41 Intentionally Omitted.

     5.42 Title to Properties and Assets. The Borrower Partnership does not own,

     5.43 License; Permits; etc. Except for licenses, permits or authorizations
previously obtained by the Borrower Partnership, no other material license,
permit or authorization is necessary to own and operate the Borrower
Partnership's business as such is presently conducted and neither the conduct of
the Borrower Partnership's business nor any material portion thereof is
dependent on the issuance or obtaining of any other license, permit or
authorization.

     5.44 Liabilities. Except for the Loan, the Borrower Partnership has no
indebtedness for borrowed money and the Borrower Partnership has not, directly

defaults on the Loan after Closing. The Borrower Partnership has conducted its
business only in the ordinary course and, except for the Loan and the Borrower

Partnership has not created, permitted or allowed any mortgage, pledge, lien,
security interest, encumbrance, restriction or charge of any kind with respect
to any of its properties, businesses or assets.

     (a) All federal, state, local and foreign tax returns and information
statements required to be filed by or on behalf of the Borrower Partnership or

party on or prior to Closing.

for an amount less than the outstanding principal balance of the Loan as of
Closing or to make any payment of principal under the Loan, except as part of
regularly scheduled amortization payments or as otherwise required by the holder
of the Loan under the Loan Documents, or change the terms in a manner that would
change the Loan from nonrecourse to recourse within the meaning of Section 752
of the Code and the regulations promulgated thereunder.

     (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
allocations required by Code Section 704(c) relating to the interests in the
Transferor Partnership contributed by the Transferor Partners and the assets of
the Transferor Partnership.

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

     12.01 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 the provisions of 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 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) principal and interest paid or payable under the Note; except to the
extent such amounts are distributed as cash prior to Closing in accordance with
the last paragraph of Section 12.01, the Transferor Partners shall receive a
credit for any real estate tax, insurance and other escrows and reserves, if
any, held by Lender as set forth in the Lender Estoppel Letter;

     (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.



                                      -54-

     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. Transferor
Agent and the BRI Partnership shall cooperate in the furnishing of all
information and documentation necessary to prepare such calculations. Prior to
Closing, the Transferor Agent shall deliver to the BRI Partnership the final
Transferor Allocation Schedule (the "Transferor Allocation Schedule"), which
shall be based upon the Preliminary Transferor Allocation Schedule, shall
incorporate all adjustments and prorations to be made pursuant to Section 12,
and shall set forth (i) the name of each Transferor Partner, (ii) the number of
Unrestricted Distribution BRI Partnership Units to be received by each
Transferor Partner, and (iii) the number of Restricted Distribution BRI
Partnership Units to be received by each Transferor Partner. The BRI Partnership
shall have no obligation or liability with respect to the preparation or
accuracy of the Preliminary Transferor Allocation Schedule or the Transferor
Allocation Schedule or the distribution of the BRI Partnership Units or the BRI
Additional Payment, if applicable, to the Transferor Partners and the Transferor
Partners hereby release the BRI Partnership from any such obligation or
liability.

     All cash, including the escrow deposits set forth in Schedule C, shall be
used by the Transferor Partnership to pay amounts payable by the Transferor
Partnership and/or distributed to the Transferor Partners prior to the Closing,
and if any of such cash applicable to pre-closing periods is not removed from
the Transferor Partnership prior to Closing, the BRI Partnership shall hold such
cash as agent for the Transferor Partners, and refund such cash to the
Transferor Partners subsequent to Closing.

     12.02 Application of Rent Payments. If any tenant is in arrears in the
payment of rent on the Closing Date, the Transferor Partnership shall distribute
the right to receive such rent to the Transferor Partners immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Partners 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 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 cause the Transferor Partnership to 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 Partners 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.

     12.03 Security Deposits. The Transferor Partnership 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.

     12.04 Election of Form of Payment. If, as a result of the prorations and
apportionments set forth in Section 12.01, the Transferor Partners owe an amount
to the BRI Partnership, the Transferor Partnership shall have the right to elect
on behalf of the Transferor Partners to adjust for such amounts owing by the
Transferor Partners 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 Partners, 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 Partners 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
Partnership shall have elected to settle adjustments under Section 12.

                                   SECTION 13

required to remove all Monetary Liens.

under this Agreement, the Transferor Partners 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

obligations hereunder, the BRI Partnership, at its option, shall have the right

event the BRI Partnership shall have the right to recover from the Transferor
Partners the amount of all reasonable legal fees, court costs and other

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 Partners in lieu
of all other rights and remedies which the BRI Partnership may have against the
Transferor Partners 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

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

willfully refuses to perform the BRI Partnership's obligations hereunder, the
Transferor Partners, jointly, but not severally, at their option, shall have the
right to compel specific performance by the BRI Partnership hereunder, in which
event the Transferor Partners 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 Partners in connection with the
exercise of their 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 Partners in the event of a default by the BRI Partnership in lieu
of all other rights and remedies which the Transferor Partners may have against

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
Partners 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 or the Transferor Partnership have any obligation to pay any
commission to APC.

transfer fee and other related costs and expenses (not to exceed in the

the BRI Partnership subject to the Notes and other Loan Documents as
contemplated hereby.

partner. The BRI Partnership shall supply any and all documentation and
additional information required by Lender in order to promptly complete the
request for the consent of Lender to the transactions contemplated hereunder.
The Transferor Partnership shall request that Lender state in writing any terms
and requirements, including the amount of any Loan Assumption Fees, to be
imposed by Lender in connection with its consent to the transactions
contemplated hereby. It shall be a condition of Closing that prior to October
15, 1997, Lender shall have granted its consent to the transactions contemplated
hereunder on terms and requirements reasonably satisfactory to the BRI
Partnership, shall have issued the Lender Estoppel Letter and shall have agreed
to release the Transferor Partners from all liability under the Loan Documents.
In the event that any of the terms or requirements required by Lender for its
consent are not approved by the BRI Partnership, the BRI Partnership may
terminate this Agreement by written notice given to the Transferor Partners
within fifteen (15) business days after the BRI Partnership have received in
writing the terms and requirements of Lender for its consent. In the event
either (a) the consent of Lender is not obtained prior to the Closing or (b) the
BRI Partnership does not approve the terms and conditions of Lender, including
the amount of any Loan Assumption Fees in excess of 1% of the unpaid principal
balance, and the BRI Partnership gives timely notice of termination hereunder to
the Transferor Agent, this Agreement shall terminate without further action by
any party, and, thereafter this Agreement shall be void and without recourse to
all parties, except for provisions which are expressly stated to survive
termination of this Agreement. In the event the Lender shall not have agreed to
release the Transferor Partners from all liability under the Loan Documents or
the Lender shall have placed terms and conditions on the Transferor Partners
that are unacceptable to them, the Transferor Agent may terminate this Agreement
by written notice given to the BRI Partnership within fifteen (15) business days
after the Transferor Agent has received in writing notice that the Lender has
refused to release the Transferor Partners from liability under the Loan
Documents or has imposed such unacceptable terms and conditions. If the
Transferor Agent gives timely notice of termination to the BRI Partnership, this
Agreement shall terminate without further action by any party, and, 



                                      -63-

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

     17.04 Public Offering Condition. BRI has informed the Transferor Partners
that in connection with the consummation of the various Related Transactions (as
defined in Section 17.05 hereof), BRI intends to undertake either or both of (i)
a public offering of common stock or other equity securities of BRI (the "Public
Offering"), or (ii) a private placement of common stock or other equity
securities of BRI (the "Private Placement"). The Transferor Partners shall
supply any documentation and additional information required by BRI in order to
complete the offering materials in connection with the Public Offering or the
Private Placement. The obligation of the BRI Partnership to proceed with the
Closing of the transactions contemplated by this Agreement is expressly
conditioned upon the successful completion of the Public Offering and the
Private Placement raising a minimum of $75,000,000.00. If the Public Placement
and the Private Placement do not in the aggregate complete offerings which raise
a minimum of $75,000,000 as aforesaid prior to the Closing Date hereunder, the
BRI Partnership shall have the right to terminate this Agreement effective as of
the Closing Date, and, thereafter this Agreement 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 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.

to collectively herein as the "Parties."

         This Agreement contemplates a tax-free merger of the Management Company
into BRI. In such merger, the Stockholders will receive capital stock of BRI in
exchange for their capital stock of the Management Company.

         Now, therefore, in consideration of the representations, warranties and
covenants herein contained, the Parties agree as follows.


         1.       The Merger.

                  1.1 The Merger. Upon and subject to the terms and conditions
of this Agreement, the Management Company shall merge with and into BRI (with
such merger referred to herein as the "Merger") at the Effective Time (as
defined below). From and after the Effective Time, the separate corporate
existence of the Management Company shall cease and BRI shall continue as the
surviving corporation in the Merger (the "Surviving Corporation"). The
"Effective Time" shall be the time at which BRI and the Management Company file
the certificate of merger or other appropriate documents prepared and executed
in accordance with the relevant provisions of the Delaware General Corporation
Law (the "Certificate of Merger") with the Secretary of State of the State of
Delaware and the Maryland General Corporation Law with the Department of
Assessments and Taxation of the State of Maryland. The Merger shall have the
effects set forth in Section 259 of the Delaware General Corporation Law.

                  1.2 The Closing. The closing of the transactions contemplated
by this Agreement (the "Closing") shall take place at the offices of Hale and
Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at such other place
as the Parties may mutually agree, at 10:00 a.m. local time on a date ("Closing
Date") mutually agreed to in writing by the Parties, but not later than October
31, 1997.

                  1.3 Actions at the Closing. At the Closing, (a) the Management
Company shall deliver to BRI the various certificates, instruments and documents


                                      -1-
<PAGE>


referred to in Section 8.10, (b) BRI shall deliver to the Company the various
certificates, instruments and documents referred to in Section 9.9, (c) the
Management Company and BRI shall file with the Secretary of State of the State
of Delaware the Certificate of Merger, (d) the Management Company and BRI shall
file with the Department of Assessments and Taxation of the State of Maryland
the Articles of Merger, (e) BRI shall deliver certificates for the BRI Shares
(as defined below) to the Stockholders, and (f) the Stockholders shall deliver
certificates for the Company Shares (as defined below).

                  1.4 Additional Action. BRI may, at any time after the
Effective Time, take any action, including executing and delivering any
document, in the name and on behalf of the Management Company, in order to
consummate the transactions contemplated by this Agreement.

                  1.5 Conversion of Shares.

                           (a) At the Effective Time, by virtue of the Merger
and without any action on the part of any Party, each share of common stock,
$1.00 par value per share, of the Management Company ("Company Shares") issued
and outstanding immediately prior to the Effective Time shall be converted into
and represent the right to receive such number of shares of common stock, $.01
par value per share, of BRI ("BRI Common Stock") as is equal to one share of BRI
Common Stock multiplied by the Conversion Ratio. The "Conversion Ratio" shall be
determined by dividing (i) the number of shares of BRI Common Stock equal in
value (as such value is determined at the time and in the manner provided herein
below) to $255,680 (the "Consideration Amount"), by (ii) the number of Company
Shares issued and outstanding immediately prior to the Effective Time; provided,
however, with respect to each property set forth on Exhibit 1 attached hereto,
as to which the transactions described in the applicable Related Agreement (as
defined in Section 11.6) have not been closed on or prior to the Closing Date
hereunder (a "Non-Acquired Property"), there shall be a reduction in the
Consideration Amount equal to the Reduction Amount for such property. The
Reduction Amount for each such property shall be equal to (A) .6 multiplied by
the amount of the Management Fees for such property as set forth on Exhibit 1
multiplied by (B) five (5). The shares of BRI Common Stock to be issued to the
holders of the Company Shares are referred to herein as the "BRI Shares."

                           (b) The Parties agree that, for purposes of this
Agreement, the value of each share of BRI Common Stock ("BRI Share 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 


                                      -2-
<PAGE>


pricing of the Public Offering contemplated under Section 11.5 hereof, provided
that in any event the BRI Share 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 Share 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.

                           (c) The Management Company and the Stockholders
acknowledge and agree that after the execution hereof, the price of the BRI
Common Stock may increase or decrease in value as the result of market
fluctuations prior and subsequent to the Public Offering. Notwithstanding these
fluctuations, once the value and number of BRI Shares have been established as
provided in this Section 1.5, BRI will not be required to increase or be
permitted to decrease the number of BRI Shares to be issued to the Stockholders
in the event of a decrease or increase in the market value of the BRI Common
Stock subsequent to the closing of the Public Offering and the fixing of the
Offering Price.

                  1.6 Fractional Shares. In the event that any Shareholder
would be entitled to a fractional share of BRI Common Stock, the number of
shares of BRI Common Stock shall be rounded up or down, as the case may be, to
the nearest whole share of BRI Common Stock.

                  1.7 Certificate of Incorporation. The Certificate of
Incorporation of the Surviving Corporation shall be the same as the Certificate
of Incorporation of BRI immediately prior to the Effective Time.

                  1.8 By-laws. The By-laws of the Surviving Corporation shall
be the same as the By-laws of BRI immediately prior to the Effective Time.

                  1.9 Directors and Officers. The directors of BRI shall remain
the directors of the Surviving Corporation as of the Effective Time. The
officers of BRI shall remain as officers of the Surviving Corporation after the
Effective Time, retaining their respective positions.

                  1.10 No Further Rights. From and after the Effective Time, no
Company Shares shall be deemed to be outstanding, and holders of Certificates
shall cease to have any rights with respect thereto, except as provided herein
or by law.

                  1.11 Closing of Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of Company
Shares shall thereafter be made.

         2. Representations with respect to the Management Company. The
Management Company on behalf of itself and each of the Stockholders, severally
and not jointly, represents and warrants to BRI as follows:

duly organized, validly existing and in good standing under the laws of the
state of Maryland. The Management Company has all requisite power and authority
(corporate and other) to own its properties, to carry on its business as now
being conducted, to execute and deliver this Agreement and the agreements
contemplated herein and to consummate the transactions contemplated hereby and
thereby to be consummated by it. The Management Company is duly qualified to do
business and is in good standing in all other jurisdictions in which the failure
to be so qualified and in good standing would have a material adverse effect on
the Management Company's business (a "Material Adverse Effect"). Such
jurisdictions are set forth on Schedule 2.1 attached hereto.

                  2.2 Capitalization of the Management Company. The authorized
capital stock of the Management Company is as set forth on Schedule 2.2 attached
hereto, including the number of Company Shares outstanding. Such Company Shares
are held of record and beneficially owned by the Stockholders as set forth on
Schedule 2.2 attached hereto. All of such Company Shares have been duly and
validly issued, are fully paid and nonassessable and free of all preemptive
rights and were issued in compliance with applicable federal and state
securities laws. There are no outstanding or authorized options, warrants,
rights, agreements or commitments to which the Management Company is a party or
which are binding upon the Management Company providing for the issuance,
disposition or acquisition of any of its capital stock. There are no outstanding
or authorized stock appreciation, phantom stock or similar rights with respect
to the Management Company. There are no agreements, voting trusts, proxies, or
understandings with respect to the voting, or registration under the Securities
Act, of any Company Shares.

                  2.3 Authorization. The execution and delivery of this
Agreement and the agreements provided for herein by the Management Company, and
the consummation by the Management Company of all transactions contemplated
hereby and thereby to be consummated by it, have been duly authorized by all
requisite corporate and shareholder action. This Agreement and all such other
agreements and obligations entered into and undertaken in connection with the
transactions contemplated hereby to which the Management Company is a party
constitute the valid and legally binding obligations of the Management Company,
enforceable against the Management Company in accordance with their respective
terms, subject


                                      -4-
<PAGE>


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. The execution, delivery and
performance by the Management Company of this Agreement and the agreements
provided for herein, and the consummation by the Management Company of the
transactions contemplated hereby and thereby, will not, with or without the
giving of notice or the passage of time or both, (a) violate the provisions of
any law, rule or regulation applicable to the Management Company; (b) violate
the provisions of the Certificate of Incorporation or By-laws of the Management
Company; (c) violate any judgment, decree, order or award of any court,
governmental body or arbitrator which would have a Material Adverse Effect; or
(d) conflict with or result in the breach or termination of any term or
provision of, or constitute a default under, or cause any acceleration under, or
cause the creation of any lien, charge or encumbrance upon the properties or
assets of the Management Company pursuant to, any indenture, mortgage, deed of
trust or other instrument or agreement to which the Management Company is a
party or by which the Management Company or any of its properties is or may be
bound which would have a Material Adverse Effect. Schedule 2.3 attached hereto
sets forth a true, correct and complete list of all material consents and
approvals of third parties that are required in connection with the consummation
by the Management Company of the transactions contemplated by this Agreement and
the agreements provided for herein.

                  2.4 Assets. Excluded Assets shall mean all assets of the
Management Company (including cash attributable to periods prior to the Closing)
other than (i) the Contracts and (ii) the assets set forth on Schedule 2.4
hereto. The Management Company shall distribute the Excluded Assets prior to
Closing to the Shareholders. Upon the Closing, the Management Company will own
all tangible assets set forth on Schedule 2.4 attached hereto.

                  2.5 Financial Statements. Attached hereto as Schedule 2.5 are
unaudited financial statements of the Management Company, including balance
sheets, statements of operations and statements of partners' capital for the
fiscal year ended December 31, 1996 (the "December 31 Financial Statements") and
on or before August 31, 1997 the Management Company shall provide unaudited
financial statements (the "Current Financial Statements") for the six-month
period ending June 30, 1997 (the "Balance Sheet Date"). The December 31
Financial Statements, the Current Financial Statements and the Closing Financial
Statement to be delivered pursuant to Section 6.8 are collectively referred to
as the "Financial Statements". The Financial Statements fairly present the
financial condition of the Management Company as of the respective statement
dates in accordance with generally accepted accounting principles consistently

liabilities, fixed, contingent or otherwise, required to be


                                      -5-
<PAGE>


disclosed in such Financial Statements in accordance with generally accepted
accounting principles (subject, in the case of any unaudited interim financial
statements, to normal year end adjustments). The Financial Statements shall be
certified by the Management Company's chief financial officer.

                  2.6 Absence of Undisclosed Liabilities. Except as and to the

Financial Statement (and the notes thereto) of the Management Company, (b) set
forth on Schedule 2.6 attached hereto or (c) incurred in the ordinary course of
business after the Balance Sheet Date and not material in amount, either
individually or in the aggregate, the Management Company does not have any
material liability or obligation, secured or unsecured, whether accrued,
absolute, contingent, unasserted or otherwise, affecting the Assets. As of the
date of Closing, the Management Company shall have no liabilities or obligations
(absolute or contingent) for borrowed money and shall have no other liabilities
or obligations (absolute or contingent) of any kind, other than (a) liabilities
and obligations incurred in the ordinary course of the Management Company's
business which are either (i) in the aggregate, not material, or (ii) approved

$50,000.

                  2.7 Litigation. Except as set forth on Schedule 2.7 attached
hereto, there is no material action, suit or, to the knowledge of the Management
Company or the Stockholders, proceeding or investigation pending or threat
thereof, against the Management Company or the Stockholders which questions the
validity of this Agreement or the right of the Management Company or the
Stockholders to enter into it, or which might result in or have, either
individually or in the aggregate, a Material Adverse Effect on the Management
Company. The Management Company is not in violation of or in default with
respect to any judgment, order, writ, injunction, decree or rule of any court,
administrative agency or governmental authority or any regulation of any
administrative agency or governmental authority except for such violations or
defaults which would not have a Material Adverse Effect.

complete list of all insurance policies of the Management Company (the
"Insurance Policies") and a list of all presently outstanding claims thereunder.

afforded by the Insurance Policies. To the Management Company's knowledge, there
are no material disputes with underwriters of any such Insurance Policies and
there are no pending or threatened terminations with respect to any of such
policies.

                  2.9 Change in Financial Condition and Assets. Except as set
forth on Schedule 2.9 attached hereto or as contemplated by this Agreement,
since the Balance Sheet Date, there has been no change which materially and
adversely affects the business, properties, assets, condition (financial or
otherwise) or prospects of the Management Company. Neither the Management
Company, nor the Stockholders, has any knowledge of any existing or threatened

Company and the Stockholders, the Management Company is not in breach of or

                  3.1 Authorization. Such Stockholder has full power and
authority to enter into and deliver this Agreement and the other agreements
provided for herein and to consummate the transactions contemplated hereby and
thereby. This Agreement and all such other agreements and obligations entered
into and undertaken in connection with the transactions contemplated hereby
constitute the valid and legally binding obligations of such Stockholder,
enforceable against such Stockholder 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. The execution, delivery
and performance by such Stockholder of this Agreement and the agreements
provided for herein, and the consummation by such Stockholder of the
transactions contemplated hereby and thereby, will not, with or without the
giving of notice or the passage of time or both, (a) violate the provisions of
any law, rule or regulation applicable to such Stockholder; (b) violate any
judgment, decree, order or award of any court, governmental body or arbitrator;
or (c) conflict with or result in the breach or termination of any term or
provision of, or constitute a default under, or cause any acceleration under, or
cause the creation of any lien, charge or encumbrance upon the Company Shares of
such Stockholder pursuant to, any indenture, mortgage, deed of trust or other
instrument or agreement to which such Stockholder is a party or by 


                                      -12-
<PAGE>


which such Stockholder is or may be bound. Schedule 3.1 attached hereto sets
forth a true, correct and complete list of all consents and approvals of third
parties that are required in connection with the consummation by such
Stockholder of the transactions contemplated by this Agreement.

                  3.2 Investment.

                            (a) Such Stockholder is acquiring the BRI Shares 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 Shares except in compliance with the registration
requirements or exemption provisions of any applicable securities laws and in
accordance with the terms of the Registration Rights Agreement (as defined
below).

                            (b) Such Stockholder understands that the BRI Shares
to be issued to Stockholder 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 reliance on such exemptions is predicated in part on the accuracy and
completeness of the representations and warranties of such Stockholder.

                            (c) Such Stockholder acknowledges and agrees that,
for the reasons set forth in paragraphs (a) and (b) above, the BRI Shares may

Stockholder 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 Shares may be made without registration under the Act, together with
either registration or an exemption under applicable Blue Sky Laws, or (iii)
upon BRI receiving an opinion of counsel knowledgeable in securities law matters
(and which opinion and counsel shall be reasonably acceptable to 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, such
Stockholder must bear the economic risk of an investment in the BRI Shares for
an indefinite period of time. Such Stockholder acknowledges, represents and
agrees that (i) his or her economic circumstances are such that he or she is
able to bear all risks of the investment in BRI and the BRI Shares for an
indefinite period of time, including the risk of a complete loss of his or her
investment in the BRI Shares, (ii) he or she has knowledge and experience in
financial and business matters sufficient to evaluate the risks of investment in
BRI, and (iii) he or she has consulted with his or her own separate counsel and
tax advisor, to the extent necessary, as to all legal and taxation matters
covered by this

Agreement and has not relied upon BRI, its affiliates or its 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 his or her acquisition of the
BRI Shares. Such Stockholder further acknowledges and represents that he or she
has made his or her own independent investigation of BRI and the business
conducted or proposed to be conducted by BRI.

                            (d) Such Stockholder is an "accredited investor"
within the meaning of Rule 501(a) promulgated under the Act.

                            (e) Such Stockholder understands that an investment

connection with this Agreement and the transactions contemplated hereby, (ii)
received and read or had the opportunity to review all documents and information
relevant to its decision to enter into this Agreement and to invest in BRI,

Private Placement Memorandum of BRI, dated as of August 25, 1997 (the "PPM") and
(iii) had the opportunity to ask questions of BRI and its management concerning
his or her investment in BRI and the transactions contemplated hereby, which
questions were answered to his or her satisfaction.

                            (f) Such Stockholder acknowledges and agrees that:

                               (i) the BRI Shares to be acquired by him or her
         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;

<PAGE>


or conflict with or violate, any provision of the Certificate of

parties proceed to Closing, each Stockholder agrees, severally and not jointly,
to indemnify and hold BRI harmless against and with respect to (i) any loss or
damage (including reasonable attorney's fees) to BRI subsequent to the Closing
Date resulting from (A) any inaccuracy in or breach of any representation or
warranty of the Management Company or of such Stockholder or (B) resulting from
any breach or default by the Management Company or such Stockholder of any
obligation of the Management Company or such Stockholder under this Agreement or
(ii) from liabilities for borrowed money incurred by the Management Company
prior to the Closing; provided that no Stockholder shall be required to
indemnify BRI for any amounts in excess of 50% of the fair market value of the
BRI shares received by such Stockholder as of the date such indemnification
obligation is satisfied (except for indemnification obligations with respect to
representations of each of the Stockholders in Section 3.2, which shall be
limited to 100% of the fair market value as of the date such indemnification
obligation is satisfied of the BRI Shares received by such Stockholder
(collectively, the "Cap"); and provided further that to the extent any of the
Stockholders have any indemnification obligation to BRI, the Stockholder may
elect to satisfy such indemnification obligation by directing BRI to cancel such
amount of BRI shares acquired by such Stockholder pursuant to this Agreement
having a fair market value (measured at the time such BRI shares are returned or
cancelled) equal to the indemnification obligation of such Stockholder.

                           (b) The BRI Partnership's Indemnity. In the event the
parties proceed to Closing, BRI agrees to indemnify and hold the Stockholder
harmless against and with respect to (i) any loss or damage (including

of BRI or (B) resulting from any breach or default by BRI of any obligation of
BRI under this Agreement or (ii) from liabilities of the Management Company
accruing after the Closing (including liabilities accruing after the Closing in
connection with employee benefit plans) (except for such liabilities resulting
from a breach or default by the Stockholder or the Management Company for which
BRI is indemnified under Section 9(a) above); provided that BRI shall not be
required to indemnify any Stockholder under Section 9(b)(i) for any amounts in
excess of 50% of the fair market value as of the date such 


                                      -26-
<PAGE>


indemnification obligation is satisfied of the BRI shares received by such
Stockholder (except for indemnification obligations with respect to Section 4.10
which shall be limited to 100% of the fair market value as of the date such
indemnification obligation is satisfied of the BRI shares received by such
Stockholder; and

                           (c) The indemnification obligations of the
Stockholders and BRI, respectively, with respect to any representation or
warranty, shall be limited to claims made prior to the last date of survival
thereof set forth in Section 14. No such claim for indemnification shall be
deemed due and 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 BRI nor any of the Stockholders shall
have any liability for claims made under Section 9(a) or 9(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 9
shall be the sole and exclusive remedy after the Closing Date for damages
available to BRI or the Stockholders 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 BRI or the Management Company.

                           (g) Each of the Stockholders, the Management Company
and BRI 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.

                           (h) Promptly after receipt by any party hereto of
notice of the commencement of any action to which any party is entitled to
indemnification under this Section 9, such party shall use its best efforts to
notify each other party hereto in writing of the commencement of such action. In
case any such action is brought, the Stockholders shall be entitled, but shall
not be required, to participate in the defense 


                                      -27-
<PAGE>


thereof, or the Stockholders may elect to take charge of and control the defense
of such action, provided that the stockholders shall agree to pursue the defense
of such action or claim in good faith by appropriate actions or proceedings
promptly taken or instituted and diligently pursued.

                  11.4 BRI's Default. If as of the Closing Date, BRI has failed
to perform all of its material obligations under this Agreement, BRI shall be in
default under this Agreement, and the Management Company shall be entitled to
terminate this Agreement by written notice given to BRI within seven days after

Management Company desires to consummate the Merger in accordance with the terms
of this Agreement and BRI willfully refuses to perform its obligations
hereunder, the Management Company, at its option, shall have the right to compel
specific performance by BRI to close the transaction, in which event the
Management Company (and the Stockholders) shall have the right to recover from

                  11.5 Public Offering Condition. BRI has informed the
Management Company and the Shareholders that in connection with the consummation
of the various Related Transactions (as defined in Section 11.6 hereof), BRI
intends to undertake either or both of (i) a public offering of common stock or
other equity securities of BRI (the "Public Offering"), or (ii) a private
placement of common stock or other equity securities of BRI (the "Private
Placement"). The Management Company and the Shareholders shall supply any
documentation and additional information required by BRI in order to complete
the offering materials in connection with the Public Offering or the Private
Placement. The obligation of BRI to proceed with the Closing of the transactions
contemplated by this Agreement is expressly conditioned upon the successful
completion of the Public Offering and the Private Placement raising a minimum of
$75,000,000.00. If the Public Placement and the Private Placement do not in the
aggregate complete offerings which raise a minimum of $75,000,000 as aforesaid
prior to the Closing Date hereunder, BRI shall have the right to terminate this
Agreement effective as of the Closing Date, and, thereafter this Agreement shall
be void and without recourse to all parties except for provisions which are

including this Agreement, for the conveyance of partnership interests or
property interests or other assets and for the making of certain secured loans,
which agreements are more particularly described on Exhibit 4 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 [as such term is defined in the
Related Agreements] (the "Kickout Agreement"), in the 


                                      -29-
<PAGE>


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,
unless such date is extended by the written consent of all of the parties
hereto, 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, unless such date is extended by the written consent
of all of the parties hereto, 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.

         12. Brokers/Allocation of Expenses/Apportionments

                  12.1 Brokers. The Parties mutually represent and warrant that
none 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 Management Company 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 Stockholders and QPI in accordance with the provisions of
Section 12.3 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 BRI or the Management Company have any
obligation to pay any commission to APC.

                  12.2 Allocation of Transaction Costs. Each Stockholder hereby
acknowledges and agrees that a portion of the amount due to such Stockholder
will be used to pay the fees and expenses attributable to the transaction
contemplated by this Agreement, which fees and expenses are the several
obligations of the Stockholder pursuant to the terms of this Agreement. Each
Stockholder and the Management Company 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 Management Company 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 purposes of this Section 12.2, each of the
Stockholders hereby agrees that: (i) QPI shall be entitled to an aggregate
administrative fee of $200,000 in connection with the concurrent 


                                      -30-
<PAGE>


contribution of up to eighteen (18) properties and the management companies, as
described in the PPM by certain transferor partnerships and related entities
(collectively, the "Related Entities"), which shall be Indirect Costs (ii) to
the extent it is determined that APC is due any fee as described in Section 12.1
hereof, up to $1,000,000 of such fee (which may be paid at Closing or held back
in an escrow account by Questar Investment Corporation 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
Questar Investment Corporation shall also be Indirect Costs. Each of the
Stockholders acknowledges and agrees that (i) any and all Direct Costs shall be
allocated to each of them with respect to their interest in the Management
Company and (ii) any and all Indirect Costs shall be allocated among the
Stockholders and Related Entities at Closing based on the pro rata number of BRI
shares allocated at Closing to each of them. Each of the Stockholders further
acknowledges and agrees that Questar Investment Corporation shall be authorized
to determine the allocations of the transaction costs and expenses to be
allocated in accordance with the provisions of this Section 12.2.

                  12.3 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 cash:

                           (a) prepaid and collected fees received under any of
the Contracts;

                           (b) wages and pension benefits of all persons
employed by the Management Company;

                           (c) charges or prepayments under the Contracts; and

                           (d) all other income and expenses relating to the
Management Company.

         If as of the Closing Date, any items of income or expense attributable
to the Management Company 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.

         At least five (5) days prior to the Closing Date, the Shareholders and
BRI shall prepare and exchange preliminary calculations of all adjustments and
prorations to be made pursuant to this Section 12.3. The Stockholders and BRI
shall cooperate in 


                                      -31-
<PAGE>


the furnishing of all information and documentation necessary to prepare such
calculations.

         All cash shall be used by the Management Company to pay all amounts
payable by the Management Company and any excess, together with all Excluded
Assets, shall be distributed to the Shareholders prior to Closing, and if any of
such excess cash applicable to pre-closing periods is not removed from the
Management Company prior to Closing, BRI shall hold such cash as agent for the
Shareholders, and refund such cash to the Shareholders subsequent to Closing.

                             THE MANAGEMENT COMPANY



<PAGE>


                          AGREEMENT AND PLAN OF MERGER


         Agreement entered into as of August 25, 1997 by and among Berkshire
Realty Company, Inc., a Delaware corporation ("BRI"), The Questar Management
Company, a Maryland corporation (the "Management Company"), and the stockholders
set forth on Schedule 2.2 attached hereto (collectively the "Stockholders").
BRI, the Management Company and the Stockholders are referred to collectively
herein as the "Parties."

         This Agreement contemplates a tax-free merger of the Management Company
into BRI. In such merger, the Stockholders will receive capital stock of BRI in
exchange for their capital stock of the Management Company.

         Now, therefore, in consideration of the representations, warranties and
covenants herein contained, the Parties agree as follows.


         1.       The Merger.

                  1.1 The Merger. Upon and subject to the terms and conditions
of this Agreement, the Management Company shall merge with and into BRI (with
such merger referred to herein as the "Merger") at the Effective Time (as
defined below). From and after the Effective Time, the separate corporate
existence of the Management Company shall cease and BRI shall continue as the
surviving corporation in the Merger (the "Surviving Corporation"). The
"Effective Time" shall be the time at which BRI and the Management Company file
the certificate of merger or other appropriate documents prepared and executed
in accordance with the relevant provisions of the Delaware General Corporation
Law (the "Certificate of Merger") with the Secretary of State of the State of
Delaware and the Maryland General Corporation Law with the Department of
Assessments and Taxation of the State of Maryland. The Merger shall have the
effects set forth in Section 259 of the Delaware General Corporation Law.

                  1.2 The Closing. The closing of the transactions contemplated
by this Agreement (the "Closing") shall take place at the offices of Hale and
Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at such other place
as the Parties may mutually agree, at 10:00 a.m. local time on a date ("Closing
Date") mutually agreed to in writing by the Parties, but not later than October
31, 1997.

                  1.3 Actions at the Closing. At the Closing, (a) the Management
Company shall deliver to BRI the various certificates, instruments and documents
referred to in Section 8.10, (b) BRI shall deliver to the Company the various
certificates, instruments and documents referred to in Section 9.9, (c) the
Management 


                                      -1-
<PAGE>


Company and BRI shall file with the Secretary of State of the State of Delaware
the Certificate of Merger, (d) the Management Company and BRI shall file with
the Department of Assessments and Taxation of the State of Maryland the Articles
of Merger, (e) BRI shall deliver certificates for the BRI Shares (as defined
below) to the Stockholders, and (f) the Stockholders shall deliver certificates
for the Company Shares (as defined below).

                  1.4 Additional Action. BRI may, at any time after the
Effective Time, take any action, including executing and delivering any
document, in the name and on behalf of the Management Company, in order to
consummate the transactions contemplated by this Agreement.

                  1.5  Conversion of Shares.

                           (a) At the Effective Time, by virtue of the Merger
and without any action on the part of any Party, each share of common stock,
$1.00 par value per share, of the Management Company ("Company Shares") issued
and outstanding immediately prior to the Effective Time shall be converted into
and represent the right to receive such number of shares of common stock, $.01
par value per share, of BRI ("BRI Common Stock") as is equal to one share of BRI
Common Stock multiplied by the Conversion Ratio. The "Conversion Ratio" shall be
determined by dividing (i) the number of shares of BRI Common Stock equal in
value (as such value is determined at the time and in the manner provided herein
below) to $2,676,010 (the "Consideration Amount"), by (ii) the number of Company
Shares issued and outstanding immediately prior to the Effective Time; provided,
however, with respect to each property set forth on Exhibit 1 attached hereto,
as to which the transactions described in the applicable Related Agreement (as
defined in Section 11.6) have not been closed on or prior to the Closing Date
hereunder (a "Non-Acquired Property"), there shall be a reduction in the
Consideration Amount equal to the Reduction Amount for such property. The
Reduction Amount for each such property shall be equal to (A) .6 multiplied by
the amount of the Management Fees for such property as set forth on Exhibit 1
multiplied by (B) five (5). The shares of BRI Common Stock to be issued to the
holders of the Company Shares are referred to herein as the "BRI Shares."

                           (b) The Parties agree that, for purposes of this
Agreement, the value of each share of BRI Common Stock ("BRI Share 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 11.5 hereof, provided that in any event the BRI Share 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 Share
Value (including the Fixed Floor and Fixed Ceiling) will be 


                                      -2-
<PAGE>


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.

                           (c) The Management Company and the Stockholders
acknowledge and agree that after the execution hereof, the price of the BRI
Common Stock may increase or decrease in value as the result of market
fluctuations prior and subsequent to the Public Offering. Notwithstanding these
fluctuations, once the value and number of BRI Shares have been established as
provided in this Section 1.5, BRI will not be required to increase or be
permitted to decrease the number of BRI Shares to be issued to the Stockholders
in the event of a decrease or increase in the market value of the BRI Common
Stock subsequent to the closing of the Public Offering and the fixing of the
Offering Price.

                  1.6 Fractional Shares. In the event that any Shareholder would
be entitled to a fractional share of BRI Common Stock, the number of shares of
BRI Common Stock shall be rounded up or down, as the case may be, to the nearest
whole share of BRI Common Stock.

                  1.7 Certificate of Incorporation. The Certificate of
Incorporation of the Surviving Corporation shall be the same as the Certificate
of Incorporation of BRI immediately prior to the Effective Time.

                  1.8 By-laws. The By-laws of the Surviving Corporation shall be
the same as the By-laws of BRI immediately prior to the Effective Time.

                  1.9 Directors and Officers. The directors of BRI shall remain
the directors of the Surviving Corporation as of the Effective Time. The
officers of BRI shall remain as officers of the Surviving Corporation after the
Effective Time, retaining their respective positions.

                  1.10 No Further Rights. From and after the Effective Time, no
Company Shares shall be deemed to be outstanding, and holders of Certificates
shall cease to have any rights with respect thereto, except as provided herein
or by law.

                  1.11 Closing of Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of Company
Shares shall thereafter be made.


                                      -3-

         2. Representations with respect to the Management Company.  The
Management Company on behalf of itself and each of the Stockholders, severally
and not jointly, represents and warrants to BRI as follows:

                  2.1 Organization. The Management Company is a corporation duly
organized, validly existing and in good standing under the laws of the state of
Maryland. The Management Company has all requisite power and authority
(corporate and other) to own its properties, to carry on its business as now
being conducted, to execute and deliver this Agreement and the agreements
contemplated herein and to consummate the transactions contemplated hereby and
thereby to be consummated by it. The Management Company is duly qualified to do
business and is in good standing in all other jurisdictions in which the failure
to be so qualified and in good standing would have a material adverse effect on
the Management Company's business (a "Material Adverse Effect"). Such
jurisdictions are set forth on Schedule 2.1 attached hereto.

                  2.2 Capitalization of the Management Company. The authorized
capital stock of the Management Company is as set forth on Schedule 2.2 attached
hereto, including the number of Company Shares outstanding. Such Company Shares
are held of record and beneficially owned by the Stockholders as set forth on
Schedule 2.2 attached hereto. All of such Company Shares have been duly and
validly issued, are fully paid and nonassessable and free of all preemptive
rights and were issued in compliance with applicable federal and state
securities laws. There are no outstanding or authorized options, warrants,
rights, agreements or commitments to which the Management Company is a party or
which are binding upon the Management Company providing for the issuance,
disposition or acquisition of any of its capital stock. There are no outstanding
or authorized stock appreciation, phantom stock or similar rights with respect
to the Management Company. There are no agreements, voting trusts, proxies, or
understandings with respect to the voting, or registration under the Securities
Act, of any Company Shares.

                  2.3 Authorization. The execution and delivery of this
Agreement and the agreements provided for herein by the Management Company, and
the consummation by the Management Company of all transactions contemplated
hereby and thereby to be consummated by it, have been duly authorized by all
requisite corporate and shareholder action. This Agreement and all such other
agreements and obligations entered into and undertaken in connection with the
transactions contemplated hereby to which the Management Company is a party
constitute the valid and legally binding obligations of the Management Company,
enforceable against the Management Company 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. The
execution, delivery and performance by the


                                      -4-
<PAGE>


Management Company of this Agreement and the agreements provided for herein, and
the consummation by the Management Company of the transactions contemplated
hereby and thereby, will not, with or without the giving of notice or the
passage of time or both, (a) violate the provisions of any law, rule or
regulation applicable to the Management Company; (b) violate the provisions of
the Certificate of Incorporation or By-laws of the Management Company; (c)
violate any judgment, decree, order or award of any court, governmental body or
arbitrator which would have a Material Adverse Effect; or (d) conflict with or
result in the breach or termination of any term or provision of, or constitute a
default under, or cause any acceleration under, or cause the creation of any
lien, charge or encumbrance upon the properties or assets of the Management
Company pursuant to, any indenture, mortgage, deed of trust or other instrument
or agreement to which the Management Company is a party or by which the
Management Company or any of its properties is or may be bound which would have
a Material Adverse Effect. Schedule 2.3 attached hereto sets forth a true,
correct and complete list of all material consents and approvals of third
parties that are required in connection with the consummation by the Management
Company of the transactions contemplated by this Agreement and the agreements
provided for herein.

                  2.4 Assets. Excluded Assets shall mean all assets of the
Management Company (including cash attributable to periods prior to the Closing)
other than (i) the Contracts and (ii) the assets set forth on Schedule 2.4
hereto. The Management Company shall distribute the Excluded Assets prior to
Closing to the Shareholders. Upon the Closing, the Management Company will own
all tangible assets set forth on Schedule 2.4 attached hereto.

                  2.5 Financial Statements. Attached hereto as Schedule 2.5 are
unaudited financial statements of the Management Company, including balance
sheets, statements of operations and statements of partners' capital for the
fiscal year ended December 31, 1996 (the "December 31 Financial Statements") and
on or before August 31, 1997 the Management Company shall provide unaudited
financial statements (the "Current Financial Statements") for the six-month
period ending June 30, 1997 (the "Balance Sheet Date"). The December 31
Financial Statements, the Current Financial Statements and the Closing Financial
Statement to be delivered pursuant to Section 6.8 are collectively referred to
as the "Financial Statements". The Financial Statements fairly present the
financial condition of the Management Company as of the respective statement
dates in accordance with generally accepted accounting principles consistently
applied (except as may be indicated in the notes thereto), and reflect all
liabilities, fixed, contingent or otherwise, required to be disclosed in such
Financial Statements in accordance with generally accepted accounting principles
(subject, in the case of any unaudited interim financial statements, to normal
year end adjustments). The Financial Statements shall be certified by the
Management Company's chief financial officer.

                  2.6 Absence of Undisclosed Liabilities. Except as and to the
extent (a) reflected in the December 31 Financial Statements and the Current
Financial Statement (and the notes thereto) of the Management Company, (b) set
forth on Schedule 2.6 attached hereto or (c) incurred in the ordinary course of
business after the Balance Sheet Date and not material in amount, either
individually or in the aggregate, the Management Company does not have any
material liability or obligation, secured or unsecured, whether accrued,
absolute, contingent, unasserted or otherwise, affecting the Assets. As of the
date of Closing, the Management Company shall have no liabilities or obligations
(absolute or contingent) for borrowed money and shall have no other liabilities
or obligations (absolute or contingent) of any kind, other than (a) liabilities
and obligations incurred in the ordinary course of the Management Company's
business which are either (i) in the aggregate, not material, or (ii) approved
by the BRI Partnership in writing; and (b) liabilities resulting from or
incurred in the ordinary course of business arising under the Contracts. For
purposes of this Subsection 2.6, "material" means any amount in excess of
$50,000.

                  2.7 Litigation. Except as set forth on Schedule 2.7 attached
hereto, there is no material action, suit or, to the knowledge of the Management
Company or the Stockholders, proceeding or investigation pending or threat
thereof, against the Management Company or the Stockholders which questions the
validity of this Agreement or the right of the Management Company or the
Stockholders to enter into it, or which might result in or have, either
individually or in the aggregate, a Material Adverse Effect on the Management
Company. The Management Company is not in violation of or in default with
respect to any judgment, order, writ, injunction, decree or rule of any court,
administrative agency or governmental authority or any regulation of any
administrative agency or governmental authority except for such violations or
defaults which would not have a Material Adverse Effect.

                  2.8 Insurance. Set forth on Schedule 2.8 hereto is a true and
complete list of all insurance policies of the Management Company (the
"Insurance Policies") and a list of all presently outstanding claims thereunder.
The Management Company has done nothing to reduce or impair the insurance

descriptions, and (iii) all annual reports filed on IRS Form 5500, 5500C or

material respects in accordance with its terms and each of the Management
Company and the ERISA Affiliates has in all material respects met its
obligations with respect to such Employee Benefit Plan and has made all required
contributions thereto. The Management Company and all Employee Benefit Plans are
in compliance in all material respects with the currently applicable provisions
of ERISA and the Code and the regulations thereunder.

                           (c) There are no investigations by an governmental
entity, termination proceedings or other claims (except claims for benefits
payable in the normal operation of the Employee Benefit Plans and proceedings
with respect to qualified domestic relations orders), suits or proceedings
against or involving any Employee Benefit Plan or asserting any rights or claims
to benefits under any Employee Benefit Plan that could give rise to any material
liability.

                           (d) All the Employee Benefit Plans that are intended
to be qualified under Section 401(a) of the Code have received determination
letters from the Internal Revenue Service to the effect that such Employee
Benefit Plans are qualified and the plans and the trusts related thereto are
exempt from federal income taxes under Sections 401(a) and 501(a), respectively,
of the Code, no such determination letter has been revoked and revocation has
not been threatened, no such Employee Benefit Plan has been amended since the
date of its most recent determination letter or application therefor in any
respect, and no act or omission has occurred, that would likely result in a
revocation of such determination.

                           (e) Neither the Management Company nor any ERISA
Affiliate has ever maintained an Employee Benefit Plan subject to Section 412 of
the Code or Title IV of ERISA.

ERISA Affiliate been obligated to contribute to any "multiemployer plan" (as
defined in Section 4001(a)(3) of ERISA).

                           (g) There are no unfunded obligations under any
Employee Benefit Plan providing benefits after termination of employment to any
employee of the Management Company (or to any beneficiary of any such employee),
including but not limited to retiree health coverage and deferred compensation,
but excluding continuation of health coverage required to be continued under
Section 4980B of the Code and insurance conversion privileges under state law.

                  3.1 Authorization. Such Stockholder has full power and
authority to enter into and deliver this Agreement and the other agreements
provided for herein and to consummate the transactions contemplated hereby and
thereby. This Agreement and all such other agreements and obligations entered
into and undertaken in connection with the transactions contemplated hereby
constitute the valid and legally binding obligations of such Stockholder,
enforceable against such Stockholder in accordance with their respective terms,
subject only to applicable bankruptcy, insolvency, reorganization, moratorium

and performance by such Stockholder of this Agreement and the agreements
provided for herein, and the consummation by such Stockholder of the

giving of notice or the passage of time or both, (a) violate the provisions of
any law, rule or regulation applicable to such Stockholder; (b) violate any
judgment, decree, order or award of any court, governmental body or arbitrator;
or (c) conflict with or result in the breach or termination of any term or
provision of, or constitute a default under, or cause any acceleration under, or
cause the creation of any lien, charge or encumbrance upon the Company Shares of
such Stockholder pursuant to, any indenture, mortgage, deed of trust or other
instrument or agreement to which such Stockholder is a party or by which such
Stockholder is or may be bound. Schedule 3.1 attached hereto sets forth a true,
correct and complete list of all consents and approvals of third parties that

                  3.2 Investment.

                           (a) Such Stockholder is acquiring the BRI Shares 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 Shares except in compliance with the registration
requirements or exemption provisions of any applicable securities laws and in

below).

                           (b) Such Stockholder understands that the BRI Shares
to be issued to Stockholder 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 reliance on 


                                      -12-
<PAGE>


such exemptions is predicated in part on the accuracy and completeness of the
representations and warranties of such Stockholder.

                           (c) Such Stockholder acknowledges and agrees that,
for the reasons set forth in paragraphs (a) and (b) above, the BRI Shares may
not be offered, sold, transferred, pledged, or otherwise disposed of by such

by the Securities and Exchange Commission to the effect that a proposed transfer
of the BRI Shares may be made without registration under the Act, together with
either registration or an exemption under applicable Blue Sky Laws, or (iii)
upon BRI receiving an opinion of counsel knowledgeable in securities law matters
(and which opinion and counsel shall be reasonably acceptable to 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, such
Stockholder must bear the economic risk of an investment in the BRI Shares for
an indefinite period of time. Such Stockholder acknowledges, represents and
agrees that (i) his or her economic circumstances are such that he or she is
able to bear all risks of the investment in BRI and the BRI Shares for an
indefinite period of time, including the risk of a complete loss of his or her
investment in the BRI Shares, (ii) he or she has knowledge and experience in
financial and business matters sufficient to evaluate the risks of investment in
BRI, and (iii) he or she has consulted with his or her own separate counsel and

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 his or her
acquisition of the BRI Shares. Such Stockholder further acknowledges and
represents that he or she has made his or her own independent investigation of
BRI and the business conducted or proposed to be conducted by BRI.

                           (d) Such Stockholder is an "accredited investor"
within the meaning of Rule 501(a) promulgated under the Act.

                           (e) Such Stockholder understands that an investment
in BRI involves substantial risks; such Stockholder acknowledges that he or she
has (i) been given full and complete access to BRI and its management in
connection with this Agreement and the transactions contemplated hereby, (ii)

his or her investment in BRI and the transactions contemplated hereby, which
questions were answered to his or her satisfaction.

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

             Intentionally omitted.

         11. Termination of Agreement

                  11.1 Termination by Lapse of Time. This Agreement shall
terminate at 5:00 p.m., Boston time, on October 31, 1997, if the transactions
contemplated hereby have not been consummated, unless such date is extended by
the written consent of all of the parties hereto.

                  11.2 Termination by Agreement of the Parties. This Agreement
may be terminated by the mutual written agreement of the Parties. In the event
of such termination by agreement, BRI shall have no further obligation or
liability to the Management Company and the Stockholders under this Agreement,
and the Management Company and the Stockholders shall have no further obligation
or liability to BRI under this Agreement.

                  11.3 Management Company's or Stockholders' Default. If as of
the Closing Date, the Management Company or the Stockholders have failed to
perform all of their respective material obligations under this Agreement, the
Management Company and the Stockholders shall be in default under this
Agreement, and BRI shall be entitled to terminate this Agreement by written
notice given to the Management Company and the Stockholders within seven 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 BRI
desires to consummate the Merger in accordance with the terms of this Agreement
and the Management Company or the Stockholders willfully refuse to perform their
respective obligations hereunder, BRI, at its option, shall have the right to
compel specific performance by the Management Company and the Stockholders to
close the transaction hereunder, in which event BRI shall have the right to
recover from the Management Company and the Stockholders the amount of all
reasonable legal fees, court costs and other litigation expenses incurred by BRI
in connection with the exercise of its right of specific performance.

                  11.4 BRI's Default. If as of the Closing Date, BRI has failed
to perform all of its material obligations under this Agreement, BRI shall be in
default under this Agreement, and the Management Company shall be entitled to
terminate this Agreement by written notice given to BRI within seven days after

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
Management Company desires to consummate the Merger in accordance with the terms
of this Agreement and BRI


                                      -27-
<PAGE>


willfully refuses to perform its obligations hereunder, the Management Company,
at its option, shall have the right to compel specific performance by BRI to
close the transaction, in which event the Management Company (and the
Stockholders) shall have the right to recover from BRI the amount of all
reasonable legal fees, court costs and other litigation expenses incurred in
connection with the exercise of their right of specific performance.

                  11.5 Public Offering Condition. BRI has informed the
Management Company and the Shareholders that in connection with the consummation
of the various Related Transactions (as defined in Section 11.6 hereof), BRI
intends to undertake either or both of (i) a public offering of common stock or
other equity securities of BRI (the "Public Offering"), or (ii) a private
placement of common stock or other equity securities of BRI (the "Private
Placement"). The Management Company and the Shareholders shall supply any
documentation and additional information required by BRI in order to complete
the offering materials in connection with the Public Offering or the Private
Placement. The obligation of BRI to proceed with the Closing of the transactions
contemplated by this Agreement is expressly conditioned upon the successful
completion of the Public Offering and the Private Placement raising a minimum of
$75,000,000.00. If the Public Placement and the Private Placement do not in the
aggregate complete offerings which raise a minimum of $75,000,000 as aforesaid
prior to the Closing Date hereunder, BRI shall have the right to terminate this
Agreement effective as of the Closing Date, and, thereafter this Agreement shall
be void and without recourse to all parties except for provisions which are
expressly stated to survive termination of this Agreement.

                  11.6 Related Agreements. Simultaneously herewith, BRI and
affiliates of BRI have 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 agreements are more particularly described on Exhibit 4 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 [as such term is defined in the
Related Agreements] (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, unless such date is extended by the written
consent of all of the parties hereto, 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, unless such date
is extended by the written consent of all of the parties hereto, whereupon this
Agreement shall be void and without recourse to all parties, except for
provisions which are expressly 


                                      -28-
<PAGE>


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.

         12. Brokers/Allocation of Expenses/Apportionments

                  12.1 Brokers. The Parties mutually represent and warrant that
none 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 Management Company 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 Stockholders and QPI in accordance with the provisions of
Section 12.3 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 BRI or the Management Company have any
obligation to pay any commission to APC.

                  21.2 Allocation of Transaction Costs. Each Stockholder hereby
acknowledges and agrees that a portion of the amount due to such Stockholder
will be used to pay the fees and expenses attributable to the transaction
contemplated by this Agreement, which fees and expenses are the several
obligations of the Stockholder pursuant to the terms of this Agreement. Each
Stockholder and the Management Company 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 Management Company 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 purposes of this Section 12.2, each of the
Stockholders 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 certain transferor partnerships and related entities (collectively, the
"Related Entities"), which shall be Indirect Costs (ii) to the extent it is
determined that APC is due any fee as described in Section 12.1 hereof, up to
$1,000,000 of such fee (which may be paid at Closing or held back in an escrow
account by Questar Investment Corporation 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 Questar
Investment Corporation shall also be Indirect Costs. Each of the Stockholders
acknowledges and agrees that (i) any and all Direct Costs shall be allocated to
each of them with respect to their interest in the Management Company and (ii)
any and all Indirect Costs shall be allocated among 


                                      -29-
<PAGE>


the Stockholders and Related Entities at Closing based on the pro rata number of
BRI shares allocated at Closing to each of them. Each of the Stockholders
further acknowledges and agrees that Questar Investment Corporation shall be
authorized to determine the allocations of the transaction costs and expenses to
be allocated in accordance with the provisions of this Section 12.2.

                  12.3 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 cash:

                           (a) prepaid and collected fees received under any of
the Contracts;

                           (b) wages and pension benefits of all persons
employed by the Management Company;

                           (c) charges or prepayments under the Contracts; and

                           (d) all other income and expenses relating to the
Management Company.

         If as of the Closing Date, any items of income or expense attributable
to the Management Company 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.

         At least five (5) days prior to the Closing Date, the Shareholders and
BRI shall prepare and exchange preliminary calculations of all adjustments and
prorations to be made pursuant to this Section 12.3. The Stockholders and BRI
shall cooperate in the furnishing of all information and documentation necessary
to prepare such calculations.

         All cash shall be used by the Management Company to pay all amounts
payable by the Management Company and any excess, together with all Excluded
Assets, shall be distributed to the Shareholders prior to Closing, and if any of
such excess cash applicable to pre-closing periods is not removed from the
Management Company prior to Closing, BRI shall hold such cash as agent for the
Shareholders, and refund such cash to the Shareholders subsequent to Closing.

<PAGE>

                          AGREEMENT AND PLAN OF MERGER


     Agreement entered into as of August 25, 1997 by and among Berkshire 
Realty Company, Inc., a Delaware corporation ("BRI"), The Kingswood Management 
Company, a Maryland corporation (the "Management Company"), and the 
stockholders set forth on Schedule 2.2 attached hereto (collectively the 
"Stockholders").  BRI, the Management Company and the Stockholders are 
referred to collectively herein as the "Parties."

     This Agreement contemplates a tax-free merger of the Management Company 
into BRI.  In such merger, the Stockholders will receive capital stock of BRI 
in exchange for their capital stock of the Management Company.

     Now, therefore, in consideration of the representations, warranties and 
covenants herein contained, the Parties agree as follows.


     1.     The Merger.

          1.1    The Merger.  Upon and subject to the terms and conditions of 
this Agreement, the Management Company shall merge with and into BRI (with 
such merger referred to herein as the "Merger") at the Effective Time (as 
defined below). From and after the Effective Time, the separate corporate 
existence of the Management Company shall cease and BRI shall continue as the 
surviving corporation in the Merger (the "Surviving Corporation").  The 
"Effective Time" shall be the time at which BRI and the Management Company 
file the certificate of merger or other appropriate documents prepared and 
executed in accordance with the relevant provisions of the Delaware General 
Corporation Law (the "Certificate of Merger") with the Secretary of State of 
the State of Delaware and the Maryland General Corporation Law with the 
Department of Assessments and Taxation of the State of Maryland.  The Merger 
shall have the effects set forth in Section 259 of the Delaware General 
Corporation Law.

          1.2     The Closing.  The closing of the transactions contemplated by 
this Agreement (the "Closing") shall take place at the offices of Hale and 
Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at such other place 
as the Parties may mutually agree, at 10:00 a.m. local time on a date 
("Closing Date") mutually agreed to in writing by the Parties, but not later 
than October 31, 1997.

          1.3     Actions at the Closing.  At the Closing, (a) the Management 
Company shall deliver to BRI the various certificates, instruments and 
documents referred to in Section 8.10, (b) BRI shall deliver to the Company 
the various certificates, instruments and documents referred to in Section 
9.9, (c) the Management

Company and BRI shall file with the Secretary of State of the State of Delaware
the Certificate of Merger, (d) the Management Company and BRI shall file with
the Department of Assessments and Taxation of the State of Maryland the Articles
of Merger, (e) BRI shall deliver certificates for the BRI Shares (as defined
below) to the Stockholders, and (f) the Stockholders shall deliver certificates
for the Company Shares (as defined below).

          1.4     Additional Action.  BRI may, at any time after the Effective 
Time, take any action, including executing and delivering any document, in the 
name and on behalf of the Management Company, in order to consummate the 
transactions contemplated by this Agreement.

          1.5     Conversion of Shares. 

               (a)     At the Effective Time, by virtue of the Merger and 
without any action on the part of any Party, each share of common stock, no 
par value per share, of the Management Company ("Company Shares") issued and 
outstanding immediately prior to the Effective Time shall be converted into 
and represent the right to receive such number of shares of common stock, $.01 
par value per share, of BRI ("BRI Common Stock") as is equal to one share of 
BRI Common Stock multiplied by the Conversion Ratio.  The "Conversion Ratio" 
shall be determined by dividing (i) the number of shares of BRI Common Stock 
equal in value (as such value is determined at the time and in the manner 
provided herein below) to $65,755 

(the "Consideration Amount"), by (ii) the number of Company Shares issued and 
outstanding immediately prior to the Effective Time; provided, however, with 
respect to each property set forth on Exhibit 1 attached hereto, as to which 
the transactions described in the applicable Related Agreement (as defined in 
Section 11.6) have not been closed on or prior to the Closing Date hereunder 
(a "Non-Acquired Property"), there shall be a reduction in the Consideration 
Amount equal to the Reduction Amount for such property.  The Reduction Amount 
for each such property shall be equal to (A) .6 multiplied by the amount of 
the Management Fees for such property as set forth on Exhibit 1 multiplied by 
(B) five (5).  The shares of BRI Common Stock to be issued to the holders of 
the Company Shares are referred to herein as the "BRI Shares."

               (b)     The Parties agree that, for purposes of this Agreement, 
the value of each share of BRI Common Stock ("BRI Share 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 11.5 hereof, provided that in any event the BRI Share 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 Share Value 
(including the Fixed Floor and Fixed Ceiling) will be 



                                      -2-

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.

               (c)     The Management Company and the Stockholders acknowledge 
and agree that after the execution hereof, the price of the BRI Common Stock 
may increase or decrease in value as the result of market fluctuations prior 
and subsequent to the Public Offering.  Notwithstanding these fluctuations, 
once the value and number of BRI Shares have been established as provided in 
this Section 1.5, BRI will not be required to increase or be permitted to 
decrease the number of BRI Shares to be issued to the Stockholders in the 
event of a decrease or increase in the market value of the BRI Common Stock 
subsequent to the closing of the Public Offering and the fixing of the 
Offering Price. 

          1.6     Fractional Shares.  In the event that any Shareholder would 
be entitled to a fractional share of BRI Common Stock, the number of shares of 
BRI Common Stock shall be rounded up or down, as the case may be, to the 
nearest whole share of BRI Common Stock.

          1.7     Certificate of Incorporation.  The Certificate of 
Incorporation of the Surviving Corporation shall be the same as the 
Certificate of Incorporation of BRI immediately prior to the Effective Time.  

          1.8     By-laws.  The By-laws of the Surviving Corporation shall be 
the same as the By-laws of BRI immediately prior to the Effective Time.

          1.9     Directors and Officers.  The directors of BRI shall remain 
the directors of the Surviving Corporation as of the Effective Time.  The 
officers of BRI shall remain as officers of the Surviving Corporation after 
the Effective Time, retaining their respective positions.

          1.10    No Further Rights.  From and after the Effective Time, no 
Company Shares shall be deemed to be outstanding, and holders of Certificates 
shall cease to have any rights with respect thereto, except as provided herein 
or by law.

          1.11     Closing of Transfer Books.  At the Effective Time, the stock 
transfer books of the Company shall be closed and no transfer of Company 
Shares shall thereafter be made.

      2.     Representations with respect to the Management Company.  The 
Management Company on behalf of itself and each of the Stockholders, severally 
and not jointly, represents and warrants to BRI as follows:

          2.1     Organization.  The Management Company is a corporation duly 
organized, validly existing and in good standing under the laws of the state 
of Maryland.  The Management Company has all requisite power and authority 
(corporate and other) to own its properties, to carry on its business as now 
being conducted, to execute and deliver this Agreement and the agreements 
contemplated herein and to consummate the transactions contemplated hereby and 
thereby to be consummated by it.  The Management Company is duly qualified to 
do business and is in good standing in all other jurisdictions in which the 
failure to be so qualified and in good standing would have a material adverse 
effect on the Management Company's business (a "Material Adverse Effect").  
Such jurisdictions are set forth on Schedule 2.1 attached hereto.

          2.2    Capitalization of the Management Company.  The authorized 
capital stock of the Management Company is as set forth on Schedule 2.2 
attached hereto, including the number of Company Shares outstanding.  Such 
Company Shares are held of record and beneficially owned by the Stockholders 
as set forth on Schedule 2.2 attached hereto.  All of such Company Shares have 
been duly and validly issued, are fully paid and nonassessable and free of all 
preemptive rights and were issued in compliance with applicable federal and 
state securities laws.  There are no outstanding or authorized options, 
warrants, rights, agreements or commitments to which the Management Company is 
a party or which are binding upon the Management Company providing for the 
issuance, disposition or acquisition of any of its capital stock.  There are 
no outstanding or authorized stock appreciation, phantom stock or similar 
rights with respect to the Management Company.  There are no agreements, 
voting trusts, proxies, or understandings with respect to the voting, or 
registration under the Securities Act, of any Company Shares.  

          2.3    Authorization.  The execution and delivery of this Agreement 
and the agreements provided for herein by the Management Company, and the 
consummation by the Management Company of all transactions contemplated hereby 
and thereby to be consummated by it, have been duly authorized by all 
requisite corporate and shareholder action.  This Agreement and all such other 
agreements and obligations entered into and undertaken in connection with the 
transactions contemplated hereby to which the Management Company is a party 
constitute the valid and legally binding obligations of the Management 
Company, enforceable against the Management Company 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.  The execution, delivery and performance by the 


                                      -4-

Management Company of this Agreement and the agreements provided for herein, 
and the consummation by the Management Company of the transactions 
contemplated hereby and thereby, will not, with or without the giving of 
notice or the passage of time or both, (a) violate the provisions of any law, 
rule or regulation applicable to the Management Company; (b) violate the 
provisions of the Certificate of Incorporation or By-laws of the Management 
Company; (c) violate any judgment, decree, order or award of any court, governme
ntal body or arbitrator which would have a Material Adverse Effect; or (d) 
conflict with or result in the breach or termination of any term or provision 
of, or constitute a default under, or cause any acceleration under, or cause 
the creation of any lien, charge or encumbrance upon the properties or assets 
of the Management Company pursuant to, any indenture, mortgage, deed of trust 
or other instrument or agreement to which the Management Company is a party or 
by which the Management Company or any of its properties is or may be bound 
which would have a Material Adverse Effect.  Schedule 2.3 attached hereto sets 
forth a true, correct and complete list of all material consents and approvals 
of third parties that are required in connection with the consummation by the 
Management Company of the transactions contemplated by this Agreement and the 
agreements provided for herein.

          2.4    Assets.  Excluded Assets shall mean all assets of the 
Management Company (including cash attributable to periods prior to the 
Closing) other than (i) the Contracts and (ii) the assets set forth on 
Schedule 2.4 hereto.  The Management Company shall distribute the Excluded 
Assets prior to Closing to the Shareholders. Upon the Closing, the Management 
Company will own all tangible assets set forth on Schedule 2.4 attached 
hereto.

          2.5    Financial Statements.  Attached hereto as Schedule 2.5 are 
unaudited financial statements of the Management Company, including balance 
sheets, statements of operations and statements of partners' capital for the 
fiscal year ended December 31, 1996 (the "December 31 Financial Statements") 
and on or before August 31, 1997 the Management Company shall provide 
unaudited financial statements (the "Current Financial Statements") for the 
six-month period ending June 30, 1997 (the "Balance Sheet Date").  The 
December 31 Financial Statements, the Current Financial Statements and the 
Closing Financial Statement to be delivered pursuant to Section 6.8 are 
collectively referred to as the "Financial Statements".  The Financial 
Statements fairly present the financial condition of the Management Company as 
of the respective statement dates in accordance with generally accepted 
accounting principles consistently applied (except as may be indicated in the 
notes thereto), and reflect all liabilities, fixed, contingent or otherwise, 
required to be disclosed in such Financial Statements in accordance with 
generally accepted accounting principles (subject, in the case of any 
unaudited interim financial statements, to normal year end adjustments).  The 
Financial Statements shall be certified by the Management Company&WP1-9;s 
chief financial officer.

forth on Schedule 2.6 attached hereto or (c) incurred in the ordinary course 
of business after the Balance Sheet Date and not material in amount, either 
individually or in the aggregate, the Management Company does not have any

hereto, there is no material action, suit or, to the knowledge of the 
Management Company or the Stockholders, proceeding or investigation pending or 
threat thereof, against the Management Company or the Stockholders which 
questions the validity of this Agreement or the right of the Management 
Company or the Stockholders to enter into it, or which might result in or 
have, either individually or in the aggregate, a Material Adverse Effect on 
the Management Company.  The Management Company is not in violation of or in 
default with respect to any judgment, order, writ, injunction, decree or rule 
of any court, administrative agency or governmental authority or any 
regulation of any administrative agency or governmental authority except for 
such violations or defaults which would not have a Material Adverse Effect.  

          2.8    Insurance.  Set forth on Schedule 2.8 hereto is a true and 
complete list of all insurance policies of the Management Company (the 
"Insurance Policies") and a list of all presently outstanding claims

knowledge, there are no material disputes with underwriters of any such 
Insurance Policies and there are no pending or threatened terminations with 
respect to any of such policies.

          2.9    Change in Financial Condition and Assets.  Except as set 
forth on Schedule 2.9 attached hereto or as contemplated by this Agreement, 
since the Balance Sheet Date, there has been no change which materially and 
adversely affects the business, properties, assets, condition (financial or 
otherwise) or prospects of the Management Company.  Neither the Management 
Company, nor the Stockholders, has any knowledge of any existing or threatened 
occurrence, event or development

                    (iii)     To the knowledge of the Management Company and 
the Stockholders, the Management Company is not in breach of or default under

Management Company is not in violation of any law, regulation or ordinance

Company and the ERISA Affiliates has in all material respects met its
obligations with respect to such Employee Benefit Plan and has made all required
contributions thereto. The Management Company and all Employee Benefit Plans are
in compliance in all material respects with the currently applicable provisions
of ERISA and the Code and the regulations thereunder.

               (c)     There are no investigations by an governmental entity, 
termination proceedings or other claims (except claims for benefits payable in 
the normal operation of the Employee Benefit Plans and proceedings with 
respect to qualified domestic relations orders), suits or proceedings against 
or involving any Employee Benefit Plan or asserting any rights or claims to 
benefits under any Employee Benefit Plan that could give rise to any material 
liability.

               (d)      All the Employee Benefit Plans that are intended to be 
qualified under Section 401(a) of the Code have received determination letters 
from the Internal Revenue Service to the effect that such Employee Benefit 
Plans are qualified and the plans and the trusts related thereto are exempt 
from federal income taxes under Sections 401(a) and 501(a), respectively, of 
the Code, no such determination letter has been revoked and revocation has not 
been threatened, no such Employee Benefit Plan has been amended since the date 
of its most recent determination letter or application therefor in any 
respect, and no act or omission has occurred, that would likely result in a 
revocation of such determination.

               (e)     Neither the Management Company nor any ERISA Affiliate 
has ever maintained an Employee Benefit Plan subject to Section 412 of the 
Code or Title IV of ERISA.

               (f)     At no time has the Management Company or any ERISA 
Affiliate been obligated to contribute to any "multiemployer plan" (as defined 
in Section 4001(a)(3) of ERISA).

               (g)     There are no unfunded obligations under any Employee 
Benefit Plan providing benefits after termination of employment to any 
employee of the Management Company (or to any beneficiary of any such 
employee), including but not limited to retiree health coverage and deferred 
compensation, but excluding continuation of health coverage required to be 
continued under Section 4980B of the Code and insurance conversion privileges 
under state law.

          3.2    Investment.

               (a)     Such Stockholder is acquiring the BRI Shares 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 Shares except in compliance with the 
registration requirements or exemption provisions of any applicable securities 
laws and in accordance with the terms of the Registration Rights Agreement (as 
defined below).

               (b)     Such Stockholder understands that the BRI Shares to be 
issued to Stockholder 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 reliance on 



                                      -12-
<PAGE>

such exemptions is predicated in part on the accuracy and completeness of the
representations and warranties of such Stockholder.

               (c)     Such Stockholder acknowledges and agrees that, for the 
reasons set forth in paragraphs (a) and (b) above, the BRI Shares may not be

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 Shares may be made without registration under the Act, 
together with either registration or an exemption under applicable Blue Sky 
Laws, or (iii) upon BRI receiving an opinion of counsel knowledgeable in 
securities law matters (and which opinion and counsel shall be reasonably 
acceptable to 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, such Stockholder must bear the economic risk of an 
investment in the BRI Shares for an indefinite period of time.  Such 
Stockholder acknowledges, represents and agrees that (i) his or her economic 
circumstances are such that he or she is able to bear all risks of the 
investment in BRI and the BRI Shares for an indefinite period of time, 
including the risk of a complete loss of his or her investment in the BRI 
Shares, (ii) he or she has knowledge and experience in financial and business 
matters sufficient to evaluate the risks of investment in BRI, and (iii) he or 
she has consulted with his or her own separate counsel and tax advisor, to the

Agreement and has not relied upon BRI, its affiliates or its 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 his or her acquisition of 
the BRI Shares.  Such Stockholder further acknowledges and represents that he 
or she has made his or her own independent investigation of BRI and the 
business conducted or proposed to be conducted by BRI.  

               (d)     Such Stockholder is an "accredited investor" within the 
meaning of Rule 501(a) promulgated under the Act.

               (e)     Such Stockholder understands that an investment in BRI 
involves substantial risks; such Stockholder acknowledges that he or she has 
(i) been given full and complete access to BRI and its management in 
connection with this Agreement and the transactions contemplated hereby, (ii) 
received and read or had the opportunity to review all documents and 
information relevant to its decision to enter into this Agreement and to 
invest in BRI, including, without limitation, BRI's SEC Filings (as defined 
below) and the Private Placement Memorandum of BRI, dated as of August 25, 
1997 (the "PPM") and (iii) had the opportunity to ask questions of BRI and its 
management concerning his or her investment in BRI and the transactions 
contemplated hereby, which questions were answered to his or her satisfaction.

validly existing and in good standing under the laws of the State of Delaware 
with full power and authority to carry on its business; (b) BRI has the right, 
power and authority to issue the BRI Shares and to operate its properties and 
to carry on its business as is presently being conducted and to enter into and

contemplated hereby and any other documents and instruments relating hereto or 
thereto; (c) this Agreement and the documents to be executed and delivered by 
BRI at Closing, upon execution and delivery, will have been duly and validly 
authorized and executed by BRI and will constitute the valid and binding 
obligations of BRI, 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 (d) assuming 
compliance with the terms of this Agreement by the parties hereto other than 
BRI, the execution and delivery by BRI of this Agreement and all other 
documents and instruments contemplated hereby and the performance by BRI of 
its obligations hereunder and thereunder do not and will not constitute a 
default under, or conflict with or violate, any provision of the Certificate 
of Incorporation or By-Laws of BRI or any other material agreement to which 
BRI is a party or by which BRI is bound. 

          4.2    Annual and Quarterly Reports.  BRI has delivered to the 
Stockholders true and complete copies of the Annual Report on Form 10-K (and 
those portions of the Annual Report to Stockholders which are incorporated by

filed with the Securities and Exchange Commission, and all Quarterly Reports 
on Form 10-Q and Current Reports on Form 8-K filed by BRI with the Securities 
and Exchange Commission since December 31, 1996 (the "SEC Filings").  The 
financial statements of BRI 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 consolidated assets, liabilities and financial 
position of BRI 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 ended 
adjustments). 

          4.3    Governmental Consent, etc.  Subject to compliance with 
applicable securities laws and the filing of the Certificate of Merger as 
required by the Delaware General Corporation Law and the Articles of Merger as

all preemptive rights and of any lien, claim, change, pledge, encumbrance, 
limitation, agreement or instrument whatsoever.

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

          4.6    PPM.  The PPM, as of the date 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.

          4.7    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 will enable it to meet the requirements for

information statements required to be filed by or on behalf of BRI or for 
which BRI may have any liability have been accurately prepared in all material

indemnify and hold BRI harmless against and with respect to (i) any loss or

Date resulting from (A) any inaccuracy in or breach of any representation or 
warranty of the Management Company or of such Stockholder or (B) resulting 
from any breach or default by the Management Company or such Stockholder of 
any obligation of the Management Company or such Stockholder under this 
Agreement or (ii) from liabilities for borrowed money incurred by the 
Management Company prior to the Closing; provided that no Stockholder shall be 
required to indemnify BRI for any amounts in excess of 50% of the fair market 
value of the BRI shares received by such Stockholder as of the date such 
indemnification obligation is satisfied (except for indemnification 
obligations with respect to representations of each of the Stockholders in 
Section 3.2, which shall be limited to 100% of the fair market value as of the 
date such indemnification obligation is satisfied of the BRI Shares received 
by such Stockholder (collectively, the "Cap"); and provided further that to 
the extent any of the Stockholders have any indemnification obligation to BRI, 
the Stockholder may elect to satisfy such indemnification obligation by 
directing BRI to cancel such amount of BRI shares acquired by such Stockholder 
pursuant to this Agreement having a fair market value (measured at the time 
such BRI shares are returned or cancelled) equal to the indemnification 
obligation of such Stockholder.

               (b)     The BRI Partnership's Indemnity.  In the event the 
parties proceed to Closing, BRI agrees to indemnify and hold the Stockholder 
harmless against and with respect to (i) any loss or damage (including 
reasonable attorney's fees) to the Stockholder, subsequent to the Closing 
Date, resulting from (A) any inaccuracy in or breach of any representation or 
warranty of BRI or (B) resulting from any breach or default by BRI of any 
obligation of BRI under this Agreement or (ii) from liabilities of the 
Management Company accruing after the Closing (including liabilities accruing 
after the Closing in connection with employee benefit plans) (except for such 
liabilities resulting from a  breach or default by the Stockholder or the 
Management Company for which BRI is indemnified under Section 9(a) above); 
provided that BRI shall not be required to indemnify any Stockholder under 
Section 9(b)(i) for any amounts in excess of 50% of the fair market value as 
of the date such indemnification obligation is satisfied of the BRI shares 
received by such Stockholder (except for indemnification obligations with 
respect to Section 4.10 which shall be limited to 100% of the fair market 
value as of the date such indemnification obligation is satisfied of the BRI sha
res received by such Stockholder; and



                                      -25-
<PAGE>

                (c)     The indemnification obligations of the Stockholders 
and BRI, respectively, with respect to any representation or warranty, shall 
be limited to claims made prior to the last date of survival thereof set forth 
in Section 14.  No such claim for indemnification shall be deemed due and 
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 BRI nor any of the Stockholders shall have any 
liability for claims made under Section 9(a) or 9(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 9 shall be 
the sole and exclusive remedy after the Closing Date for damages available to 
BRI or the Stockholders 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 
BRI or the Management Company.

               (g)     Each of the Stockholders, the Management Company and 
BRI 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.

               (h)     Promptly after receipt by any party hereto of notice of 
the commencement of any action to which any party is entitled to 
indemnification under this Section 9, such party shall use its best efforts to 
notify each other party hereto in writing of the commencement of such action.  
In case any such action is brought, the Stockholders shall be entitled, but 
shall not be required, to participate in the defense thereof, or the 
Stockholders may elect to take charge of and control the defense of such 
action, provided that the stockholders shall agree to pursue the defense of 
such action or claim in good faith by appropriate actions or proceedings 
promptly taken or instituted and diligently pursued.

          11.1   Termination by Lapse of Time.  This Agreement shall terminate 
at 5:00 p.m., Boston time, on October 31, 1997, if the transactions

the written consent of all of the parties hereto.

          11.2   Termination by Agreement of the Parties.  This Agreement may 
be terminated by the mutual written agreement of the Parties.  In the event of 
such termination by agreement, BRI shall have no further obligation or

and the Management Company and the Stockholders shall have no further 
obligation or liability to BRI under this Agreement.  

          11.3   Management Company's or Stockholders' Default.  If as of the 
Closing Date, the Management Company or the Stockholders have failed to

Management Company and the Stockholders shall be in default under this 
Agreement, and BRI shall be entitled to terminate this Agreement by written 
notice given to the Management Company and the Stockholders within seven 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 BRI desires to consummate the Merger in accordance with the 
terms of this Agreement and the Management Company or the Stockholders 
willfully refuse to perform their respective obligations hereunder, BRI, at 
its option, shall have the right to compel specific performance by the 
Management Company and the Stockholders to close the transaction hereunder, in 
which event BRI shall have the right to recover from the Management Company 
and the Stockholders the amount of all reasonable legal fees, court costs and 
other litigation expenses incurred by BRI in connection with the exercise of 
its right of specific performance.

          11.4   BRI's Default.  If as of the Closing Date, BRI has failed to 
perform all of its material obligations under this Agreement, BRI shall be in 
default under this Agreement, and the Management Company shall be entitled to

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 Management Company desires to consummate the Merger in 
accordance with the terms of this Agreement and BRI 




                                      -27-
<PAGE>

willfully refuses to perform its obligations hereunder, the Management Company,
at its option, shall have the right to compel specific performance by BRI to
close the transaction, in which event the Management Company (and the
Stockholders) shall have the right to recover from BRI the amount of all
reasonable legal fees, court costs and other litigation expenses incurred in
connection with the exercise of their right of specific performance.

          11.5   Public Offering Condition.  BRI has informed the Management 
Company and the Shareholders that in connection with the consummation of the 
various Related Transactions (as defined in Section 11.6 hereof), BRI intends 
to undertake either or both of (i) a public offering of common stock or other 
equity securities of BRI (the "Public Offering"), or (ii) a private placement 
of common stock or other equity securities of BRI (the "Private Placement").  
The Management Company and the Shareholders shall supply any documentation and 
additional information required by BRI in order to complete the offering 
materials in connection with the Public Offering or the Private Placement.  
The obligation of BRI to proceed with the Closing of the transactions 
contemplated by this Agreement is expressly conditioned upon the successful 
completion of the Public Offering and the Private Placement raising a minimum 
of $75,000,000.00.  If the Public Placement and the Private Placement do not 
in the aggregate complete offerings which raise a minimum of $75,000,000 as 
aforesaid prior to the Closing Date hereunder, BRI shall have the right to 
terminate this Agreement effective as of the Closing Date, and, thereafter 
this Agreement shall be void and without recourse to all parties except for 
provisions which are expressly stated to survive termination of this 
Agreement.

          11.6   Related Agreements.  Simultaneously herewith, BRI and 
affiliates of BRI have 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 agreements are more particularly described on Exhibit 4 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 [as such term is 
defined in the Related Agreements] (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, unless such date is 
extended by the written consent of all of the parties hereto, 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, unless such date is extended by the written consent of all of the 
parties hereto, whereupon this Agreement shall be void and without recourse to 
all parties, except for provisions which are expressly 




                                      -28-
<PAGE>

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.

     12.     Brokers/Allocation of Expenses/Apportionments

          12.1   Brokers.  The Parties mutually represent and warrant that 
none 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 Management Company 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 Stockholders and QPI in 
accordance with the provisions of Section 12.3 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 BRI or the 
Management Company have any obligation to pay any commission to APC.

          12.2   Allocation of Transaction Costs.  Each Stockholder hereby 
acknowledges and agrees that a portion of the amount due to such Stockholder 
will be used to pay the fees and expenses attributable to the transaction 
contemplated by this Agreement, which fees and expenses are the several 
obligations of the Stockholder pursuant to the terms of this Agreement.  Each 
Stockholder and the Management Company 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 
Management Company 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 purposes of 
this Section 12.2, each of the Stockholders 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 certain transferor 
partnerships and related entities (collectively, the "Related Entities"), 
which shall be Indirect Costs (ii) to the extent it is determined that APC is 
due any fee as described in Section 12.1 hereof, up to $1,000,000 of such fee 
(which may be paid at Closing or held back in an escrow account by Questar 
Investment Corporation 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 Questar Investment Corporation 
shall also be Indirect Costs.  Each of the Stockholders acknowledges and 
agrees that (i) any and all Direct Costs shall be allocated to each of them 
with respect to their interest in the Management Company and (ii) any and all 
Indirect Costs shall be allocated among 



                                      -29-
<PAGE>

the Stockholders and Related Entities at Closing based on the pro rata number of
BRI shares allocated at Closing to each of them. Each of the Stockholders
further acknowledges and agrees that Questar Investment Corporation shall be
authorized to determine the allocations of the transaction costs and expenses to
be allocated in accordance with the provisions of this Section 12.2.

          12.3   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 cash:

               (a)     prepaid and collected fees received under any of the 
Contracts;

               (b)     wages and pension benefits of all persons employed by 
the Management Company;

               (c)     charges or prepayments under the Contracts; and

               (d)     all other income and expenses relating to the 
Management Company.
     If as of the Closing Date, any items of income or expense attributable to 
the Management Company 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.

     At least five (5) days prior to the Closing Date, the Shareholders and 
BRI shall prepare and exchange preliminary calculations of all adjustments and 
prorations to be made pursuant to this Section 12.3.  The Stockholders and BRI 
shall cooperate in the furnishing of all information and documentation 
necessary to prepare such calculations.

     All cash shall be used by the Management Company to pay all amounts 
payable by the Management Company and any excess, together with all Excluded 
Assets, shall be distributed to the Shareholders prior to Closing, and if any 
of such excess cash applicable to pre-closing periods is not removed from the 
Management Company prior to Closing, BRI shall hold such cash as agent for the 
Shareholders, and refund such cash to the Shareholders subsequent to Closing.

                             THE MANAGEMENT COMPANY
<PAGE>



                          AGREEMENT AND PLAN OF MERGER


     Agreement entered into as of August 25, 1997 by and among Berkshire
Realty Company, Inc., a Delaware corporation ("BRI"), The Vector Property
Management Company, a Maryland corporation (the "Management Company"), and the
stockholders set forth on Schedule 2.2 attached hereto (collectively the
"Stockholders").  BRI, the Management Company and the Stockholders are
referred to collectively herein as the "Parties."

     This Agreement contemplates a tax-free merger of the Management Company
into BRI.  In such merger, the Stockholders will receive capital stock of BRI
in exchange for their capital stock of the Management Company.

     Now, therefore, in consideration of the representations, warranties and
covenants herein contained, the Parties agree as follows.


     1.     The Merger.

          1.1    The Merger.  Upon and subject to the terms and conditions of
this Agreement, the Management Company shall merge with and into BRI (with
such merger referred to herein as the "Merger") at the Effective Time (as
defined below). From and after the Effective Time, the separate corporate
existence of the Management Company shall cease and BRI shall continue as the
surviving corporation in the Merger (the "Surviving Corporation").  The
"Effective Time" shall be the time at which BRI and the Management Company
file the certificate of merger or other appropriate documents prepared and
executed in accordance with the relevant provisions of the Delaware General
Corporation Law (the "Certificate of Merger") with the Secretary of State of
the State of Delaware and the Maryland General Corporation Law with the
Department of Assessments and Taxation of the State of Maryland.  The Merger
shall have the effects set forth in Section 259 of the Delaware General
Corporation Law.

          1.2    The Closing.  The closing of the transactions contemplated by
this Agreement (the "Closing") shall take place at the offices of Hale and
Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at such other place
as the Parties may mutually agree, at 10:00 a.m. local time on a date
("Closing Date") mutually agreed to in writing by the Parties, but not later
than October 31, 1997.

          1.3    Actions at the Closing.  At the Closing, (a) the Management
Company shall deliver to BRI the various certificates, instruments and
documents referred to in Section 8.10, (b) BRI shall deliver to the Company
the various certificates, instruments and documents referred to in Section
9.9, (c) the Management 



                                      -1-
<PAGE>

Company and BRI shall file with the Secretary of State of the State of Delaware
the Certificate of Merger, (d) the Management Company and BRI shall file with
the Department of Assessments and Taxation of the State of Maryland the Articles
of Merger, (e) BRI shall deliver certificates for the BRI Shares (as defined
below) to the Stockholders, and (f) the Stockholders shall deliver certificates
for the Company Shares (as defined below).

          1.4    Additional Action.  BRI may, at any time after the Effective
Time, take any action, including executing and delivering any document, in the
name and on behalf of the Management Company, in order to consummate the
transactions contemplated by this Agreement.

          1.5    Conversion of Shares.

               (a)     At the Effective Time, by virtue of the Merger and
without any action on the part of any Party, each share of common stock, $1.00
par value per share, of the Management Company ("Company Shares") issued and
outstanding immediately prior to the Effective Time shall be converted into and
represent the right to receive such number of shares of common stock, $.01 par
value per share, of BRI ("BRI Common Stock") as is equal to one share of BRI
Common Stock multiplied by the Conversion Ratio. The "Conversion Ratio" shall be
determined by dividing (i) the number of shares of BRI Common Stock equal in
value (as such value is determined at the time and in the manner provided herein
below) to $425,280 (the "Consideration Amount"), by (ii) the number of Company
Shares issued and outstanding immediately prior to the Effective Time; provided,
however, with respect to each property set forth on Exhibit 1 attached hereto,
as to which the transactions described in the applicable Related Agreement (as
defined in Section 11.6) have not been closed on or prior to the Closing Date
hereunder (a "Non-Acquired Property"), there shall be a reduction in the
Consideration Amount equal to the Reduction Amount for such property. The
Reduction Amount for each such property shall be equal to (A) .6 multiplied by
the amount of the Management Fees for such property as set forth on Exhibit 1
multiplied by (B) five (5). The shares of BRI Common Stock to be issued to the
holders of the Company Shares are referred to herein as the "BRI Shares."

               (b)     The Parties agree that, for purposes of this Agreement,
the value of each share of BRI Common Stock ("BRI Share 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 11.5 hereof, provided that in any event the BRI Share 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 Share Value
(including the Fixed Floor and Fixed Ceiling) will be 



                                      -2-
<PAGE>

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.

               (c)     The Management Company and the Stockholders acknowledge
and agree that after the execution hereof, the price of the BRI Common Stock
may increase or decrease in value as the result of market fluctuations prior
and subsequent to the Public Offering.  Notwithstanding these fluctuations,
once the value and number of BRI Shares have been established as provided in
this Section 1.5, BRI will not be required to increase or be permitted to
decrease the number of BRI Shares to be issued to the Stockholders in the
event of a decrease or increase in the market value of the BRI Common Stock
subsequent to the closing of the Public Offering and the fixing of the
Offering Price.

          1.6    Fractional Shares.  In the event that any Shareholder would
be entitled to a fractional share of BRI Common Stock, the number of shares of
BRI Common Stock shall be rounded up or down, as the case may be, to the
nearest whole share of BRI Common Stock.

          1.7    Certificate of Incorporation.  The Certificate of
Incorporation of the Surviving Corporation shall be the same as the
Certificate of Incorporation of BRI immediately prior to the Effective Time.

          1.8    By-laws.  The By-laws of the Surviving Corporation shall be
the same as the By-laws of BRI immediately prior to the Effective Time.

          1.9    Directors and Officers.  The directors of BRI shall remain
the directors of the Surviving Corporation as of the Effective Time.  The
officers of BRI shall remain as officers of the Surviving Corporation after
the Effective Time, retaining their respective positions.

          1.10    No Further Rights.  From and after the Effective Time, no
Company Shares shall be deemed to be outstanding, and holders of Certificates
shall cease to have any rights with respect thereto, except as provided herein
or by law.

          1.11    Closing of Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed and no transfer of Company
Shares shall thereafter be made.

                                      -3-

      2.     Representations with respect to the Management Company.  The
Management Company on behalf of itself and each of the Stockholders, severally
and not jointly, represents and warrants to BRI as follows:

          2.1    Organization.  The Management Company is a corporation duly
organized, validly existing and in good standing under the laws of the state
of Maryland.  The Management Company has all requisite power and authority
(corporate and other) to own its properties, to carry on its business as now
being conducted, to execute and deliver this Agreement and the agreements
contemplated herein and to consummate the transactions contemplated hereby and
thereby to be consummated by it.  The Management Company is duly qualified to
do business and is in good standing in all other jurisdictions in which the
failure to be so qualified and in good standing would have a material adverse
effect on the Management Company's business (a "Material Adverse Effect").
Such jurisdictions are set forth on Schedule 2.1 attached hereto.

          2.2    Capitalization of the Management Company.  The authorized
capital stock of the Management Company is as set forth on Schedule 2.2
attached hereto, including the number of Company Shares outstanding.  Such
Company Shares are held of record and beneficially owned by the Stockholders
as set forth on Schedule 2.2 attached hereto.  All of such Company Shares have
been duly and validly issued, are fully paid and nonassessable and free of all
preemptive rights and were issued in compliance with applicable federal and
state securities laws.  There are no outstanding or authorized options,
warrants, rights, agreements or commitments to which the Management Company is
a party or which are binding upon the Management Company providing for the
issuance, disposition or acquisition of any of its capital stock.  There are
no outstanding or authorized stock appreciation, phantom stock or similar
rights with respect to the Management Company.  There are no agreements,
voting trusts, proxies, or understandings with respect to the voting, or
registration under the Securities Act, of any Company Shares.

          2.3    Authorization.  The execution and delivery of this Agreement
and the agreements provided for herein by the Management Company, and the
consummation by the Management Company of all transactions contemplated hereby
and thereby to be consummated by it, have been duly authorized by all
requisite corporate and shareholder action.  This Agreement and all such other
agreements and obligations entered into and undertaken in connection with the
transactions contemplated hereby to which the Management Company is a party
constitute the valid and legally binding obligations of the Management
Company, enforceable against the Management Company 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.  The execution, delivery and performance by the



                                      -4-
<PAGE>

Management Company of this Agreement and the agreements provided for herein,
and the consummation by the Management Company of the transactions
contemplated hereby and thereby, will not, with or without the giving of
notice or the passage of time or both, (a) violate the provisions of any law,
rule or regulation applicable to the Management Company; (b) violate the
provisions of the Certificate of Incorporation or By-laws of the Management
Company; (c) violate any judgment, decree, order or award of any court, governme
ntal body or arbitrator which would have a Material Adverse Effect; or (d)
conflict with or result in the breach or termination of any term or provision
of, or constitute a default under, or cause any acceleration under, or cause
the creation of any lien, charge or encumbrance upon the properties or assets
of the Management Company pursuant to, any indenture, mortgage, deed of trust
or other instrument or agreement to which the Management Company is a party or
by which the Management Company or any of its properties is or may be bound
which would have a Material Adverse Effect.  Schedule 2.3 attached hereto sets
forth a true, correct and complete list of all material consents and approvals
of third parties that are required in connection with the consummation by the
Management Company of the transactions contemplated by this Agreement and the
agreements provided for herein.

          2.4    Assets.  Excluded Assets shall mean all assets of the
Management Company (including cash attributable to periods prior to the
Closing) other than (i) the Contracts and (ii) the assets set forth on
Schedule 2.4 hereto.  The Management Company shall distribute the Excluded
Assets prior to Closing to the Shareholders. Upon the Closing, the Management
Company will own all tangible assets set forth on Schedule 2.4 attached
hereto.

          2.5    Financial Statements.  Attached hereto as Schedule 2.5 are
unaudited financial statements of the Management Company, including balance
sheets, statements of operations and statements of partners' capital for the
fiscal year ended December 31, 1996 (the "December 31 Financial Statements")
and on or before August 31, 1997 the Management Company shall provide
unaudited financial statements (the "Current Financial Statements") for the
six-month period ending June 30, 1997 (the "Balance Sheet Date").  The
December 31 Financial Statements, the Current Financial Statements and the
Closing Financial Statement to be delivered pursuant to Section 6.8 are
collectively referred to as the "Financial Statements".  The Financial
Statements fairly present the financial condition of the Management Company as
of the respective statement dates in accordance with generally accepted
accounting principles consistently applied (except as may be indicated in the
notes thereto), and reflect all liabilities, fixed, contingent or otherwise,
required to be disclosed in such Financial Statements in accordance with
generally accepted accounting principles (subject, in the case of any
unaudited interim financial statements, to normal year end adjustments).  The
Financial Statements shall be certified by the Management Company&WP1-9;s
chief financial officer.

           2.6    Absence of Undisclosed Liabilities.  Except as and to the
extent (a) reflected in the December 31 Financial Statements and the Current
Financial Statement (and the notes thereto) of the Management Company, (b) set
forth on Schedule 2.6 attached hereto or (c) incurred in the ordinary course
of business after the Balance Sheet Date and not material in amount, either
individually or in the aggregate, the Management Company does not have any
material liability or obligation, secured or unsecured, whether accrued,
absolute, contingent, unasserted or otherwise, affecting the Assets.  As of
the date of Closing, the Management Company shall have no liabilities or
obligations (absolute or contingent) for borrowed money and shall have no
other liabilities or obligations (absolute or contingent) of any kind, other
than (a) liabilities and obligations incurred in the ordinary course of the
Management Company's business which are either (i) in the aggregate, not
material, or (ii) approved by the BRI Partnership in writing; and (b)
liabilities resulting from or incurred in the ordinary course of business
arising under the Contracts.  For purposes of this Subsection 2.6, "material"
means any amount in excess of $50,000.

          2.7    Litigation.  Except as set forth on Schedule 2.7 attached
hereto, there is no material action, suit or, to the knowledge of the
Management Company or the Stockholders, proceeding or investigation pending or
threat thereof, against the Management Company or the Stockholders which
questions the validity of this Agreement or the right of the Management
Company or the Stockholders to enter into it, or which might result in or
have, either individually or in the aggregate, a Material Adverse Effect on
the Management Company.  The Management Company is not in violation of or in
default with respect to any judgment, order, writ, injunction, decree or rule
of any court, administrative agency or governmental authority or any
regulation of any administrative agency or governmental authority except for
such violations or defaults which would not have a Material Adverse Effect.

          2.8    Insurance.  Set forth on Schedule 2.8 hereto is a true and
complete list of all insurance policies of the Management Company (the
"Insurance Policies") and a list of all presently outstanding claims
thereunder.  The Management Company has done nothing to reduce or impair the
insurance afforded by the Insurance Policies.  To the Management Company's
knowledge, there are no material disputes with underwriters of any such
Insurance Policies and there are no pending or threatened terminations with
respect to any of such policies.

          2.9    Change in Financial Condition and Assets.  Except as set
forth on Schedule 2.9 attached hereto or as contemplated by this Agreement,
since the Balance Sheet Date, there has been no change which materially and
adversely affects the business, properties, assets, condition (financial or
otherwise) or prospects of the Management Company.  Neither the Management
Company, nor the Stockholders, has any knowledge of any existing or threatened
occurrence, event or development which would have a Material Adverse Effect on
the business, properties, assets, condition or prospects of the Management
Company.

                    (i)     each Contract is a valid and binding agreement of
the Management Company, enforceable against the Management Company in
accordance with its terms, and neither the Management Company nor any
Stockholder has any knowledge that such Contract is not a valid and binding
agreement of the other parties thereto;

                    (ii)     To the knowledge of the Management Company and
the Stockholders, the Management Company has fulfilled all material

Material Adverse Effect.

               (c)     Except as set forth on Schedule 2.12, the continuation,

Management Company. Complete and accurate copies of (i) all Employee Benefits
Plans, (ii) all related trust agreements, insurance contracts and summary plan
descriptions, and (iii) all annual reports filed on IRS Form 5500, 5500C or
5500R for the last three plan years for each Employee Benefit Plan, have been

material respects in accordance with its terms and each of the Management
Company and the ERISA Affiliates has in all material respects met its
obligations with respect to such Employee Benefit Plan and has made all required
contributions thereto. The Management Company and all Employee Benefit Plans are
in compliance in all material respects with the currently applicable provisions
of ERISA and the Code and the regulations thereunder.

               (c)     There are no investigations by an governmental entity,
termination proceedings or other claims (except claims for benefits payable in
the normal operation of the Employee Benefit Plans and proceedings with
respect to qualified domestic relations orders), suits or proceedings against
or involving any Employee Benefit Plan or asserting any rights or claims to
benefits under any Employee Benefit Plan that could give rise to any material
liability.

               (d)      All the Employee Benefit Plans that are intended to be
qualified under Section 401(a) of the Code have received determination letters
from the Internal Revenue Service to the effect that such Employee Benefit
Plans are qualified and the plans and the trusts related thereto are exempt
from federal income taxes under Sections 401(a) and 501(a), respectively, of
the Code, no such determination letter has been revoked and revocation has not
been threatened, no such Employee Benefit Plan has been amended since the date
of its most recent determination letter or application therefor in any
respect, and no act or omission has occurred, that would likely result in a
revocation of such determination.

               (e)     Neither the Management Company nor any ERISA Affiliate
has ever maintained an Employee Benefit Plan subject to Section 412 of the
Code or Title IV of ERISA.

               (f)     At no time has the Management Company or any ERISA
Affiliate been obligated to contribute to any "multiemployer plan" (as defined
in Section 4001(a)(3) of ERISA).

               (g)     There are no unfunded obligations under any Employee
Benefit Plan providing benefits after termination of employment to any
employee of the Management Company (or to any beneficiary of any such
employee), including but not limited to retiree health coverage and deferred
compensation, but excluding continuation of health coverage required to be
continued under Section 4980B of the Code and insurance conversion privileges
under state law.

compliance with the terms of this Agreement by the parties hereto other than

indemnify and hold BRI harmless against and with respect to (i) any loss or
damage (including reasonable attorney's fees) to BRI subsequent to the Closing
Date resulting from (A) any inaccuracy in or breach of any representation or
warranty of the Management Company or of such Stockholder or (B) resulting
from any breach or default by the Management Company or such Stockholder of
any obligation of the Management Company or such Stockholder under this
Agreement or (ii) from liabilities for borrowed money incurred by the
Management Company prior to the Closing; provided that no Stockholder shall be
required to indemnify BRI for any amounts in excess of 50% of the fair market
value of the BRI shares received by such Stockholder as of the date such
indemnification obligation is satisfied (except for indemnification
obligations with respect to representations of each of the Stockholders in
Section 3.2, which shall be limited to 100% of the fair market value as of the
date such indemnification obligation is satisfied of the BRI Shares received
by such Stockholder (collectively, the "Cap"); and provided further that to
the extent any of the Stockholders have any indemnification obligation to BRI,
the Stockholder may elect to satisfy such indemnification obligation by
directing BRI to cancel such amount of BRI shares acquired by such Stockholder
pursuant to this Agreement having a fair market value (measured at the time
such BRI shares are returned or cancelled) equal to the indemnification
obligation of such Stockholder.

               (b)     The BRI Partnership's Indemnity.  In the event the
parties proceed to Closing, BRI agrees to indemnify and hold the Stockholder

liabilities resulting from a  breach or default by the Stockholder or the
Management Company for which BRI is indemnified under Section 9(a) above);
provided that BRI shall not be required to indemnify any Stockholder under
Section 9(b)(i) for any amounts in excess of 50% of the fair market value as
of the date such indemnification obligation is satisfied of the BRI shares

<PAGE>

                (c)     The indemnification obligations of the Stockholders
and BRI, respectively, with respect to any representation or warranty, shall
be limited to claims made prior to the last date of survival thereof set forth
in Section 14.  No such claim for indemnification shall be deemed due and
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 BRI nor any of the Stockholders shall have any
liability for claims made under Section 9(a) or 9(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 9 shall be
the sole and exclusive remedy after the Closing Date for damages available to
BRI or the Stockholders 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
BRI or the Management Company.

               (g)     Each of the Stockholders, the Management Company and
BRI 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.

               (h)     Promptly after receipt by any party hereto of notice of
the commencement of any action to which any party is entitled to
indemnification under this Section 9, such party shall use its best efforts to
notify each other party hereto in writing of the commencement of such action.
In case any such action is brought, the Stockholders shall be entitled, but
shall not be required, to participate in the defense thereof, or the
Stockholders may elect to take charge of and control the defense of such
action, provided that the stockholders shall agree to pursue the defense of
such action or claim in good faith by appropriate actions or proceedings
promptly taken or instituted and diligently pursued.

other litigation expenses incurred by BRI in connection with the exercise of
its right of specific performance.

          11.4   BRI's Default.  If as of the Closing Date, BRI has failed to

                                      -27-

willfully refuses to perform its obligations hereunder, the Management Company,
at its option, shall have the right to compel specific performance by BRI to
close the transaction, in which event the Management Company (and the
Stockholders) shall have the right to recover from BRI the amount of all
reasonable legal fees, court costs and other litigation expenses incurred in
connection with the exercise of their right of specific performance.

          11.5   Public Offering Condition.  BRI has informed the Management
Company and the Shareholders that in connection with the consummation of the
various Related Transactions (as defined in Section 11.6 hereof), BRI intends
to undertake either or both of (i) a public offering of common stock or other
equity securities of BRI (the "Public Offering"), or (ii) a private placement
of common stock or other equity securities of BRI (the "Private Placement").
The Management Company and the Shareholders shall supply any documentation and
additional information required by BRI in order to complete the offering
materials in connection with the Public Offering or the Private Placement.
The obligation of BRI to proceed with the Closing of the transactions
contemplated by this Agreement is expressly conditioned upon the successful
completion of the Public Offering and the Private Placement raising a minimum
of $75,000,000.00.  If the Public Placement and the Private Placement do not
in the aggregate complete offerings which raise a minimum of $75,000,000 as

Agreement.

          11.6   Related Agreements.  Simultaneously herewith, BRI and
affiliates of BRI have 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 agreements are more particularly described on Exhibit 4 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 [as such term is
defined in the Related Agreements] (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, unless such date is
extended by the written consent of all of the parties hereto, 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, unless such date is extended by the written consent of all of the
parties hereto, whereupon this Agreement shall be void and without recourse to
all parties, except for provisions which are expressly 



                                      -28-
<PAGE>

stated to survive the termination of this Agreement. The Closing under this
Agreement shall be simultaneous with the closings under the Related Agreements.

Agreement shall be cancelled or postponed.

     12.     Brokers/Allocation of Expenses/Apportionments

          12.1   Brokers.  The Parties mutually represent and warrant that
none 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 Management Company 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 Stockholders and QPI in
accordance with the provisions of Section 12.3 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 BRI or the
Management Company have any obligation to pay any commission to APC.

          12.2   Allocation of Transaction Costs.  Each Stockholder hereby
acknowledges and agrees that a portion of the amount due to such Stockholder
will be used to pay the fees and expenses attributable to the transaction
contemplated by this Agreement, which fees and expenses are the several
obligations of the Stockholder pursuant to the terms of this Agreement.  Each
Stockholder and the Management Company 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
Management Company 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 purposes of
this Section 12.2, each of the Stockholders 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 certain transferor
partnerships and related entities (collectively, the "Related Entities"),
which shall be Indirect Costs (ii) to the extent it is determined that APC is
due any fee as described in Section 12.1 hereof, up to $1,000,000 of such fee
(which may be paid at Closing or held back in an escrow account by Questar
Investment Corporation 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 Questar Investment Corporation
shall also be Indirect Costs.  Each of the Stockholders acknowledges and
agrees that (i) any and all Direct Costs shall be allocated to each of them
with respect to their interest in the Management Company and (ii) any and all
Indirect Costs shall be allocated among



                                      -29-
<PAGE>

the Stockholders and Related Entities at Closing based on the pro rata number of
BRI shares allocated at Closing to each of them. Each of the Stockholders
further acknowledges and agrees that Questar Investment Corporation shall be
authorized to determine the allocations of the transaction costs and expenses to
be allocated in accordance with the provisions of this Section 12.2.

          12.3   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 cash:

               (a)     prepaid and collected fees received under any of the
Contracts;

               (b)     wages and pension benefits of all persons employed by
the Management Company;

               (c)     charges or prepayments under the Contracts; and

               (d)     all other income and expenses relating to the
Management Company.

     If as of the Closing Date, any items of income or expense attributable to
the Management Company 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.

     At least five (5) days prior to the Closing Date, the Shareholders and
BRI shall prepare and exchange preliminary calculations of all adjustments and
prorations to be made pursuant to this Section 12.3.  The Stockholders and BRI
shall cooperate in the furnishing of all information and documentation
necessary to prepare such calculations.

     All cash shall be used by the Management Company to pay all amounts
payable by the Management Company and any excess, together with all Excluded
Assets, shall be distributed to the Shareholders prior to Closing, and if any
of such excess cash applicable to pre-closing periods is not removed from the
Management Company prior to Closing, BRI shall hold such cash as agent for the
Shareholders, and refund such cash to the Shareholders subsequent to Closing.

                             THE MANAGEMENT COMPANY

<PAGE>

                          AGREEMENT AND PLAN OF MERGER


     Agreement entered into as of August 25, 1997 by and among Berkshire 
Realty Company, Inc., a Delaware corporation ("BRI"), The Gorn Management 
Company, a Maryland corporation (the "Management Company"), and the 
stockholders set forth on Schedule 2.2 attached hereto (collectively the 
"Stockholders").  BRI, the Management Company and the Stockholders are 
referred to collectively herein as the "Parties."

     This Agreement contemplates a tax-free merger of the Management Company 
into BRI.  In such merger, the Stockholders will receive capital stock of BRI 
in exchange for their capital stock of the Management Company.

     Now, therefore, in consideration of the representations, warranties and 
covenants herein contained, the Parties agree as follows.


     1.     The Merger.

          1.1    The Merger.  Upon and subject to the terms and conditions of 
this Agreement, the Management Company shall merge with and into BRI (with 
such merger referred to herein as the "Merger") at the Effective Time (as 
defined below). From and after the Effective Time, the separate corporate 
existence of the Management Company shall cease and BRI shall continue as the 
surviving corporation in the Merger (the "Surviving Corporation").  The 
"Effective Time" shall be the time at which BRI and the Management Company 
file the certificate of merger or other appropriate documents prepared and 
executed in accordance with the relevant provisions of the Delaware General 
Corporation Law (the "Certificate of Merger") with the Secretary of State of 
the State of Delaware and the Maryland General Corporation Law with the 
Department of Assessments and Taxation of the State of Maryland.  The Merger 
shall have the effects set forth in Section 259 of the Delaware General 
Corporation Law.

          1.2    The Closing.  The closing of the transactions contemplated by 
this Agreement (the "Closing") shall take place at the offices of Hale and 
Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at such other place 
as the Parties may mutually agree, at 10:00 a.m. local time on a date 
("Closing Date") mutually agreed to in writing by the Parties, but not later 
than October 31, 1997.

          1.3    Actions at the Closing.  At the Closing, (a) the Management 
Company shall deliver to BRI the various certificates, instruments and 
documents 



                                      -1-
<PAGE>

referred to in Section 8.10, (b) BRI shall deliver to the Company the various
certificates, instruments and documents referred to in Section 9.9, (c) the
Management Company and BRI shall file with the Secretary of State of the State
of Delaware the Certificate of Merger, (d) the Management Company and BRI shall
file with the Department of Assessments and Taxation of the State of Maryland
the Articles of Merger, (e) BRI shall deliver certificates for the BRI Shares
(as defined below) to the Stockholders, and (f) the Stockholders shall deliver
certificates for the Company Shares (as defined below).

          1.4    Additional Action.  BRI may, at any time after the Effective 
Time, take any action, including executing and delivering any document, in the 
name and on behalf of the Management Company, in order to consummate the 
transactions contemplated by this Agreement.

          1.5    Conversion of Shares. 

               (a)     At the Effective Time, by virtue of the Merger and 
without any action on the part of any Party, each share of common stock, no par
value per share, of the Management Company ("Company Shares") issued and
outstanding immediately prior to the Effective Time shall be converted into and
represent the right to receive such number of shares of common stock, $.01 par
value per share, of BRI ("BRI Common Stock") as is equal to one share of BRI
Common Stock multiplied by the Conversion Ratio. The "Conversion Ratio" shall be
determined by dividing (i) the number of shares of BRI Common Stock equal in
value (as such value is determined at the time and in the manner provided herein
below) to $1,259,775 (the "Consideration Amount"), by (ii) the number of Company
Shares issued and outstanding immediately prior to the Effective Time; provided,
however, with respect to each property set forth on Exhibit 1 attached hereto,
as to which the transactions described in the applicable Related Agreement (as
defined in Section 11.6) have not been closed on or prior to the Closing Date
hereunder (a "Non-Acquired Property"), there shall be a reduction in the
Consideration Amount equal to the Reduction Amount for such property. The
Reduction Amount for each such property shall be equal to (A) .6 multiplied by
the amount of the Management Fees for such property as set forth on Exhibit 1
multiplied by (B) five (5). The shares of BRI Common Stock to be issued to the
holders of the Company Shares are referred to herein as the "BRI Shares."

               (b)     The Parties agree that, for purposes of this Agreement, 
the value of each share of BRI Common Stock ("BRI Share 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 




                                      -2-
<PAGE>

pricing of the Public Offering contemplated under Section 11.5 hereof, provided
that in any event the BRI Share 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 Share 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.

               (c)     The Management Company and the Stockholders acknowledge 
and agree that after the execution hereof, the price of the BRI Common Stock 
may increase or decrease in value as the result of market fluctuations prior 
and subsequent to the Public Offering.  Notwithstanding these fluctuations, 
once the value and number of BRI Shares have been established as provided in 
this Section 1.5, BRI will not be required to increase or be permitted to 
decrease the number of BRI Shares to be issued to the Stockholders in the 
event of a decrease or increase in the market value of the BRI Common Stock 
subsequent to the closing of the Public Offering and the fixing of the 
Offering Price. 

          1.6    Fractional Shares.  In the event that any Shareholder would 
be entitled to a fractional share of BRI Common Stock, the number of shares of 
BRI Common Stock shall be rounded up or down, as the case may be, to the 
nearest whole share of BRI Common Stock.

          1.7    Certificate of Incorporation.  The Certificate of 
Incorporation of the Surviving Corporation shall be the same as the 
Certificate of Incorporation of BRI immediately prior to the Effective Time.  

          1.8    By-laws.  The By-laws of the Surviving Corporation shall be 
the same as the By-laws of BRI immediately prior to the Effective Time.

          1.9    Directors and Officers.  The directors of BRI shall remain 
the directors of the Surviving Corporation as of the Effective Time.  The 
officers of BRI shall remain as officers of the Surviving Corporation after 
the Effective Time, retaining their respective positions.

          1.10    No Further Rights.  From and after the Effective Time, no 
Company Shares shall be deemed to be outstanding, and holders of Certificates 
shall cease to have any rights with respect thereto, except as provided herein 
or by law.

          1.11    Closing of Transfer Books.  At the Effective Time, the stock 
transfer books of the Company shall be closed and no transfer of Company 
Shares shall thereafter be made. 

                                      -3-

     2.     Representations with respect to the Management Company.  The 
Management Company on behalf of itself and each of the Stockholders, severally 
and not jointly, represents and warrants to BRI as follows:

          2.1    Organization.  The Management Company is a corporation duly 
organized, validly existing and in good standing under the laws of the state 
of Maryland.  The Management Company has all requisite power and authority 
(corporate and other) to own its properties, to carry on its business as now 
being conducted, to execute and deliver this Agreement and the agreements 
contemplated herein and to consummate the transactions contemplated hereby and 
thereby to be consummated by it.  The Management Company is duly qualified to 
do business and is in good standing in all other jurisdictions in which the 
failure to be so qualified and in good standing would have a material adverse 
effect on the Management Company's business (a "Material Adverse Effect").  
Such jurisdictions are set forth on Schedule 2.1 attached hereto.

          2.2    Capitalization of the Management Company.  The authorized 
capital stock of the Management Company is as set forth on Schedule 2.2 
attached hereto, including the number of Company Shares outstanding.  Such 
Company Shares are held of record and beneficially owned by the Stockholders 
as set forth on Schedule 2.2 attached hereto.  All of such Company Shares have 
been duly and validly issued, are fully paid and nonassessable and free of all 
preemptive rights and were issued in compliance with applicable federal and 
state securities laws.  There are no outstanding or authorized options, 
warrants, rights, agreements or commitments to which the Management Company is 
a party or which are binding upon the Management Company providing for the 
issuance, disposition or acquisition of any of its capital stock.  There are 
no outstanding or authorized stock appreciation, phantom stock or similar 
rights with respect to the Management Company.  There are no agreements, 
voting trusts, proxies, or understandings with respect to the voting, or 
registration under the Securities Act, of any Company Shares.  

          2.3    Authorization.  The execution and delivery of this Agreement 
and the agreements provided for herein by the Management Company, and the 
consummation by the Management Company of all transactions contemplated hereby 
and thereby to be consummated by it, have been duly authorized by all 
requisite corporate and shareholder action.  This Agreement and all such other 
agreements and obligations entered into and undertaken in connection with the 
transactions contemplated hereby to which the Management Company is a party 
constitute the valid and legally binding obligations of the Management 
Company, enforceable against the Management Company in accordance with their 
respective terms, subject 




                                      -4-
<PAGE>

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. The execution, delivery and
performance by the Management Company of this Agreement and the agreements
provided for herein, and the consummation by the Management Company of the
transactions contemplated hereby and thereby, will not, with or without the
giving of notice or the passage of time or both, (a) violate the provisions of
any law, rule or regulation applicable to the Management Company; (b) violate
the provisi ons of the Certificate of Incorporation or By-laws of the Management
Company; (c) violate any judgment, decree, order or award of any court,
governmental body or arbitrator which would have a Material Adverse Effect; or
(d) conflict with or result in the breach or termination of any term or
provision of, or constitute a default under, or cause any acceleration under, or
cause the creation of any lien, charge or encumbrance upon the properties or
assets of the Management Company pursuant to, any indenture, mortgage, deed of
trust or other instrument or agreement to which the Management Company is a
party or by which the Management Company or any of its properties is or may be
bound which would have a Material Adverse Effect. Schedule 2.3 attached hereto
sets forth a true, correct and complete list of all material consents and
approvals of third parties that are required in connection with the consummation
by the Management Company of the transactions contemplated by this Agreement and
the agreements provided for herein.

          2.4    Assets.  Excluded Assets shall mean all assets of the 
Management Company (including cash attributable to periods prior to the 
Closing) other than (i) the Contracts (except as noted on Schedule 2.12) and 
(ii) the assets set forth on Schedule 2.4 hereto.  The Management Company 
shall distribute the Excluded Assets prior to Closing to the Shareholders.  
Upon the Closing, the Management Company will own all tangible assets set 
forth on Schedule 2.4 attached hereto.

          2.5    Financial Statements.  Attached hereto as Schedule 2.5 are 
unaudited financial statements of the Management Company, including balance 
sheets, statements of operations and statements of partners' capital for the 
fiscal year ended December 31, 1996 (the "December 31 Financial Statements") 
and on or before August 31, 1997 the Management Company shall provide 
unaudited financial statements (the "Current Financial Statements") for the 
six-month period ending June 30, 1997 (the "Balance Sheet Date").  The 
December 31 Financial Statements, the Current Financial Statements and the 
Closing Financial Statement to be delivered pursuant to Section 6.8 are 
collectively referred to as the "Financial Statements".  The Financial 
Statements fairly present the financial condition of the Management Company as 
of the respective statement dates in accordance with generally accepted 
accounting principles consistently applied (except as may be indicated in the 
notes

                                      -5-
<PAGE>

thereto), and reflect all liabilities, fixed, contingent or otherwise, required
to be disclosed in such Financial Statements in accordance with generally
accepted accounting principles (subject, in the case of any unaudited interim
financial statements, to normal year end adjustments). The Financial Statements
shall be certified by the Management Company&WP1-9;s chief financial officer.

          2.6    Absence of Undisclosed Liabilities.  Except as and to the 
extent (a) reflected in the December 31 Financial Statements and the Current 
Financial Statement (and the notes thereto) of the Management Company, (b) set 
forth on Schedule 2.6 attached hereto or (c) incurred in the ordinary course 
of business after the Balance Sheet Date and not material in amount, either 
individually or in the aggregate, the Management Company does not have any 
material liability or obligation, secured or unsecured, whether accrued, 
absolute, contingent, unasserted or otherwise, affecting the Assets.  As of 
the date of Closing, the Management Company shall have no liabilities or 
obligations (absolute or contingent) for borrowed money and shall have no 
other liabilities or obligations (absolute or contingent) of any kind, other 
than (a) liabilities and obligations incurred in the ordinary course of the 
Management Company's business which are either (i) in the aggregate, not materia
l, or (ii) approved by the BRI Partnership in writing; and (b) liabilities 
resulting from or incurred in the ordinary course of business arising under 
the Contracts.  For purposes of this Subsection 2.6, "material" means any 
amount in excess of $50,000.

          2.7    Litigation.  Except as set forth on Schedule 2.7 attached 
hereto, there is no material action, suit or, to the knowledge of the 
Management Company or the Stockholders, proceeding or investigation pending or 
threat thereof, against the Management Company or the Stockholders which 
questions the validity of this Agreement or the right of the Management 
Company or the Stockholders to enter into it, or which might result in or 
have, either individually or in the aggregate, a Material Adverse Effect on 
the Management Company.  The Management Company is not in violation of or in 
default with respect to any judgment, order, writ, injunction, decree or rule 
of any court, administrative agency or governmental authority or any 
regulation of any administrative agency or governmental authority except for 
such violations or defaults which would not have a Material Adverse Effect.  

          2.8    Insurance.  Set forth on Schedule 2.8 hereto is a true and 
complete list of all insurance policies of the Management Company (the 
"Insurance Policies") and a list of all presently outstanding claims 
thereunder.  The Management Company has done nothing to reduce or impair the 
insurance afforded by the Insurance Policies.  To the Management Company's 
knowledge, there are no material 



                                      -6-
<PAGE>

disputes with underwriters of any such Insurance Policies and there are no

adversely affects the business, properties, assets, condition (financial or 
otherwise) or prospects of the Management Company.  Neither the Management

          2.17    Employee Benefits.  

               (a)     Schedule 2.17 contains a list of all employees of the 
Management Company, along with the position and the annual rate of 
compensation of each such person.  

               (b)     Schedule 2.17 contains a complete and accurate list of 
all Employee Benefit Plans (as defined below) maintained, or contributed to, 
by the Management Company or any ERISA Affiliate (as defined below).  For 
purposes of this Agreement, "Employee Benefit Plan" means any "employee 
pension benefit plan" (as defined in Section 3(2) of the Employee Retirement 
Income Security Act of 1974, as amended ("ERISA")), any "employee welfare 
benefit plan" (as defined in Section 3(1) of ERISA), and any other written 
plan, agreement or arrangement involving direct or indirect compensation, 
including without limitation insurance coverage, severance benefits, 
disability benefits, deferred compensation, bonuses, stock options, stock 
purchase, phantom stock, stock appreciation or other forms of incentive 
compensation or post-retirement compensation.  For purposes of this Agreement, 
"ERISA Affiliate" means any entity which is a member of (i) a controlled group 
of corporations (as defined in Section 414(b) of the Code), (ii) a group of 
trades or businesses under common control (as defined in Section 414(c) of the 
Code), or (iii) an affiliated service group (as defined under Section 414(m) 
of the Code or the regulations under Section 414(o) of the Code), any of which 
includes the Management Company.  Complete and accurate copies of (i) all 
Employee Benefits Plans, (ii) all related trust agreements, insurance 
contracts and summary plan descriptions, and (iii) all annual reports filed on 
IRS Form 5500, 5500C or 5500R for the last three plan years for each Employee 
Benefit Plan, have been delivered to the BRI.  Each Employee Benefit Plan has 
been administered in all material respects in accordance with its terms and 
each of the Management Company and the ERISA Affiliates has in all material 
respects met its obligations with respect to such Employee Benefit Plan and 
has made all required contributions thereto.  The Management Company and all 
Employee Benefit Plans are in compliance in all material respects with the 
currently applicable provisions of ERISA and the Code and the regulations 
thereunder.
               (c)     There are no investigations by an governmental entity, 
termination proceedings or other claims (except claims for benefits payable in 
the normal operation of the Employee Benefit Plans and proceedings with 
respect to qualified domestic relations orders), suits or proceedings against 
or involving any Employee Benefit Plan or asserting any rights or claims to 
benefits under any Employee Benefit Plan that could give rise to any material 
liability.

               (d)      All the Employee Benefit Plans that are intended to be 
qualified under Section 401(a) of the Code have received determination letters 
from 



                                      -11-
<PAGE>

the Internal Revenue Service to the effect that such Employee Benefit Plans are
qualified and the plans and the trusts related thereto are exempt from federal
income taxes under Sections 401(a) and 501(a), respectively, of the Code, no
such determination letter has been revoked and revocation has not been
threatened, no such Employee Benefit Plan has been amended since the date of its
most recent determination letter or application therefor in any respect, and no
act or omission has occurred, that would likely result in a revocation of such
determination.

               (e)     Neither the Management Company nor any ERISA Affiliate 
has ever maintained an Employee Benefit Plan subject to Section 412 of the 
Code or Title IV of ERISA.

               (f)     At no time has the Management Company or any ERISA 
Affiliate been obligated to contribute to any "multiemployer plan" (as defined 
in Section 4001(a)(3) of ERISA).

               (g)     There are no unfunded obligations under any Employee 
Benefit Plan providing benefits after termination of employment to any 
employee of the Management Company (or to any beneficiary of any such 
employee), including but not limited to retiree health coverage and deferred 
compensation, but excluding continuation of health coverage required to be 
continued under Section 4980B of the Code and insurance conversion privileges 
under state law.

     3.     Representations with respect to the Stockholders.  Each of the 
Stockholders, on behalf of his or her self, severally and not jointly, 
represents and warrants to BRI as follows:

          3.1    Authorization.  Such Stockholder has full power and authority 
to enter into and deliver this Agreement and the other agreements provided for 
herein and to consummate the transactions contemplated hereby and thereby.  
This Agreement and all such other agreements and obligations entered into and 
undertaken in connection with the transactions contemplated hereby constitute 
the valid and legally binding obligations of such Stockholder, enforceable 
against such Stockholder 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.  The execution, delivery 
and performance by such Stockholder of this Agreement and the agreements 
provided for herein, and the consummation by such Stockholder of the 
transactions contemplated hereby and thereby, will not, with or without the 
giving of notice or the passage of time or both, (a) violate the provisions of 
any law, rule or regulation applicable to such Stockholder; (b) violate any 
judgment, decree, order or award of any court, 



                                      -12-
<PAGE>

governmental body or arbitrator; or (c) conflict with or result in the breach or
termination of any term or provision of, or constitute a default under, or cause
any acceleration under, or cause the creation of any lien, charge or encumbrance
upon the Company Shares of such Stockholder pursuant to, any indenture,
mortgage, deed of trust or other instrument or agreement to which such
Stockholder is a party or by which such Stockholder is or may be bound. Schedule
3.1 attached hereto sets forth a true, correct and complete list of all consents
and approvals of third parties that are required in connection with the
consummation by such Stockholder of the transactions contemplated by this
Agreement.

          3.2    Investment.

               (a)     Such Stockholder is acquiring the BRI Shares 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 Shares except in compliance with the 
registration requirements or exemption provisions of any applicable securities 
laws and in accordance with the terms of the Registration Rights Agreement (as 
defined below).

               (b)     Such Stockholder understands that the BRI Shares to be 
issued to Stockholder 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 reliance on such exemptions is predicated in part on the accuracy 
and completeness of the representations and warranties of such Stockholder.

               (c)     Such Stockholder acknowledges and agrees that, for the 
reasons set forth in paragraphs (a) and (b) above, the BRI Shares may not be 
offered, sold, transferred, pledged, or otherwise disposed of by such 
Stockholder 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 Shares may be made without registration under the Act, 
together with either registration or an exemption under applicable Blue Sky 
Laws, or (iii) upon BRI receiving an opinion of counsel knowledgeable in 
securities law matters (and which opinion and counsel shall be reasonably 
acceptable to 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, such Stockholder must bear the economic risk of an 
investment in the BRI Shares for an indefinite period of time.  Such 
Stockholder acknowledges, represents and agrees that (i) his or her economic 
circumstances are such that he or she is able to bear all risks of the 
investment in BRI and the BRI 



                                      -13-
<PAGE>

Shares for an indefinite period of time, including the risk of a complete loss
of his or her investment in the BRI Shares, (ii) he or she has knowledge and
experience in financial and business matters sufficient to evaluate the risks of
investment in BRI, and (iii) he or she has consulted with his or her own
separate counsel and tax advisor, to the extent necessary, as to all legal and
taxation matters covered by this Agreement and has not relied upon BRI, its
affiliates or its 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 his or her acquisition of the BRI Shares. Such Stockholder
further acknowledges and represents that he or she has made his or her own
independent investigation of BRI and the business conducted or proposed to be
conducted by BRI.

               (d)     Such Stockholder is an "accredited investor" within the 
meaning of Rule 501(a) promulgated under the Act.

               (e)     Such Stockholder understands that an investment in BRI 
involves substantial risks; such Stockholder acknowledges that he or she has 
(i) been given full and complete access to BRI and its management in 
connection with this Agreement and the transactions contemplated hereby, (ii) 
received and read or had the opportunity to review all documents and 
information relevant to its decision to enter into this Agreement and to 
invest in BRI, including, without limitation, BRI's SEC Filings (as defined 
below) and the Private Placement Memorandum of BRI, dated as of August 25, 
1997 (the "PPM") and (iii) had the opportunity to ask questions of BRI and its 
management concerning his or her investment in BRI and the transactions 
contemplated hereby, which questions were answered to his or her satisfaction.

               (f)     Such Stockholder acknowledges and agrees that:

     (i)     the BRI Shares to be acquired by him or her 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)     Until such time as the following legend is no longer required, 
the BRI Shares 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

<PAGE>

               securities may not be offered, sold, transferred, pledged or
               otherwise disposed of without an effective registration statement

               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)     BRI reserves the right to place a stop order against the 
transfer of the BRI Shares and to refuse to effect any transfers thereof, in 
the absence of satisfying the conditions contained in the foregoing legend.

2.2 attached hereto is the address of such Stockholder's principal residence 
or principal place of business, and such Stockholder 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 3.2 shall survive the 
Closing indefinitely.

          3.     Receipt of Documents.  Such Stockholder has received all 
Exhibits and Schedules described herein as attached hereto.

     4.     Representations of BRI.  BRI represents and warrants as follows:

          4.1    Authority.  (a) BRI is a corporation duly organized and 
validly existing and in good standing under the laws of the State of Delaware 
with full power and authority to carry on its business; (b) BRI has the right, 
power and authority to issue the BRI Shares and to operate its properties and 
to carry on its business as is presently being conducted and to enter into and 
perform all of the agreements and covenants contained in this Agreement and 
contemplated hereby and any other documents and instruments relating hereto or 
thereto; (c) this Agreement and the documents to be executed and delivered by 
BRI at Closing, upon execution and delivery, will have been duly and validly 
authorized and executed by BRI and will constitute the valid and binding 
obligations of BRI, 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 



                                      -15-
<PAGE>

hereafter enacted to the extent that the same may be constitutionally applied;
and (d) assuming compliance with the terms of this Agreement by the parties
hereto other than BRI, the execution and delivery by BRI of this Agreement and
all other documents and instruments contemplated hereby and the performance by
BRI of its obligations hereunder and thereunder do not and will not constitute a
default under, or conflict with or violate, any provision of the Certificate of
Incorporation or By-Laws of BRI or any other material agreement to which BRI is
a party or by which BRI is bound.

          4.2    Annual and Quarterly Reports.  BRI has delivered to the 
Stockholders true and complete copies of the Annual Report on Form 10-K (and 
those portions of the Annual Report to Stockholders which are incorporated by 
reference therein) of BRI for the fiscal year ended December 31, 1996, as 
filed with the Securities and Exchange Commission, and all Quarterly Reports 
on Form 10-Q and Current Reports on Form 8-K filed by BRI with the Securities 
and Exchange Commission since December 31, 1996 (the "SEC Filings").  The 
financial statements of BRI 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 consolidated assets, liabilities and financial 
position of BRI 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 ended 
adjustments). 

          4.3    Governmental Consent, etc.  Subject to compliance with 
applicable securities laws and the filing of the Certificate of Merger as 
required by the Delaware General Corporation Law and the Articles of Merger as 
required by the Maryland General Corporation Law or except as disclosed in the 
PPM, no consent, approval or authorization of, or designation, declaration or 
filing with, any governmental agency, commission, board or public authority is 
required on the part of BRI in connection with the valid execution and 
delivery of this Agreement by BRI and the performance of BRI's obligations 
hereunder.

          4.4    Capitalization.  The authorized capital stock of BRI consists 
of 140,000,000 shares of BRI Common Stock, of which 25,797,893 shares were 
issued and outstanding as of August 1, 1997.  All of the issued and 
outstanding shares of BRI Common Stock are duly authorized, validly issued, 
fully paid, nonassessable and free of all preemptive rights.  All of the BRI 
Shares will be, when issued in accordance with this Agreement, duly 
authorized, validly issued, fully paid, nonassessable and free and clear of 
all preemptive rights and of any lien, claim, change, pledge, encumbrance, 
limitation, agreement or instrument whatsoever.

                                      -16-
<PAGE>

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

          4.6    PPM.  The PPM, as of the date 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.

          4.7    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 will enable it to meet the requirements for 
qualification and taxation as a "real estate investment trust" under the Code.

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

          4.9    Tax Matters.  

               (a)     All federal, state, local, and foreign tax returns and 
information statements required to be filed by or on behalf of BRI or for 
which BRI may have any liability have been accurately prepared in all material 
respects and duly and timely filed (or requests for extensions have been 
timely filed, granted and have not expired).  As of the date hereof, there is

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

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.

litigation expenses incurred by BRI in connection with the exercise of 
its right of specific performance.

          11.4   BRI's Default.  If as of the Closing Date, BRI has failed to 
perform all of its material obligations under this Agreement, BRI shall be in 
default under this Agreement, and the Management Company shall be entitled to 
terminate this Agreement by written notice given to BRI within seven 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 Management Company desires to consummate the Merger in 
accordance with the terms of this Agreement and BRI willfully refuses to 
perform its obligations hereunder, the Management Company, at its option, 
shall have the right to compel specific performance by BRI to close the 
transaction, in which event the Management Company (and the Stockholders) 
shall have the right to recover from BRI the amount of all reasonable legal 
fees, court costs and other litigation expenses incurred in connection with 
the exercise of their right of specific performance.  

          11.5   Public Offering Condition.  BRI has informed the Management 
Company and the Shareholders that in connection with the consummation of the 
various Related Transactions (as defined in Section 11.6 hereof), BRI intends 
to undertake either or both of (i) a public offering of common stock or other 
equity securities of BRI (the "Public Offering"), or (ii) a private placement 
of common stock or other equity securities of BRI (the "Private Placement").  
The Management Company and the Shareholders shall supply any documentation and 
additional information required by BRI in order to complete the offering 
materials in connection with the Public Offering or the Private Placement.  
The obligation of BRI to proceed with the Closing of the transactions 
contemplated by this Agreement is expressly conditioned upon the successful 
completion of the Public Offering and the Private Placement raising a minimum 
of $75,000,000.00.  If the Public Placement and the Private Placement do not 
in the aggregate complete offerings which raise a minimum of $75,000,000 as 
aforesaid prior to the Closing Date hereunder, BRI shall have the right to 
terminate this Agreement effective as of the Closing Date, and, thereafter 
this Agreement shall be void and without recourse to all parties except for 
provisions which are expressly stated to survive termination of this 
Agreement.

          11.6   Related Agreements.  Simultaneously herewith, BRI and 
affiliates of BRI have 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 agreements are more particularly described on Exhibit 4 attached 
hereto (collectively the "Related Agreements").  (The transactions described 
in the Related Agreements, including this 



                                      -29-
<PAGE>

Agreement, are collectively the "Related Transactions"). Except to the extent
the parties expressly agree otherwise in writing or in that certain Kickout
Agreement [as such term is defined in the Related Agreements] (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,
unless such date is extended by the written consent of all of the parties
hereto, 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, unless such date is extended by the written consent
of all of the parties hereto, 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.

     12.     Brokers/Allocation of Expenses/Apportionments

          12.1   Brokers.  The Parties mutually represent and warrant that 
none 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 Management Company 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 Stockholders and QPI in 
accordance with the provisions of Section 12.3 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 BRI or the 
Management Company have any obligation to pay any commission to APC.

          12.2   Allocation of Transaction Costs.  Each Stockholder hereby 
acknowledges and agrees that a portion of the amount due to such Stockholder 
will be used to pay the fees and expenses attributable to the transaction 
contemplated by this Agreement, which fees and expenses are the several 
obligations of the Stockholder pursuant to the terms of this Agreement.  Each 
Stockholder and the Management Company 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 
Management Company due to said fees solely benefiting it ("Direct Costs") and 
(ii) those fees which cannot be so allocated ("Indirect Costs"). 


                                      -30-
<PAGE>

Notwithstanding anything to the contrary contained herein, for the purposes of 
this Section 12.2, each of the Stockholders 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 certain transferor partnerships
 and related entities (collectively, the "Related Entities"), which shall be 
Indirect Costs (ii) to the extent it is determined that APC is due any fee as 
described in Section 12.1 hereof, up to $1,000,000 of such fee (which may be 
paid at Closing or held back in an escrow account by Questar Investment 
Corporation 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 Questar Investment Corporation 
shall also be Indirect Costs.  Each of the Stockholders acknowledges and 
agrees that (i) any and all Direct Costs shall be allocated to each of them 
with respect to their interest in the Management Company and (ii) any and all 
Indirect Costs shall be allocated among the Stockholders and Related Entities 
at Closing based on the pro rata number of BRI shares allocated at Closing to 
each of them.  Each of the Stockholders further acknowledges and agrees that 
Questar Investment Corporation shall be authorized to determine the 
allocations of the transaction costs and expenses to be allocated in 
accordance with the provisions of this Section 12.2.

          12.3   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 cash:

               (a)     prepaid and collected fees received under any of the 
Contracts;

               (b)     wages and pension benefits of all persons employed by 
the Management Company;

               (c)     charges or prepayments under the Contracts; and

               (d)     all other income and expenses relating to the 
Management Company.

     If as of the Closing Date, any items of income or expense attributable to 
the Management Company 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.

                                      -31-
<PAGE>

     At least five (5) days prior to the Closing Date, the Shareholders and 
BRI shall prepare and exchange preliminary calculations of all adjustments and 
prorations to be made pursuant to this Section 12.3.  The Stockholders and BRI 
shall cooperate in the furnishing of all information and documentation 
necessary to prepare such calculations.

     All cash shall be used by the Management Company to pay all amounts 
payable by the Management Company and any excess, together with all Excluded 
Assets, shall be distributed to the Shareholders prior to Closing, and if any 
of such excess cash applicable to pre-closing periods is not removed from the 
Management Company prior to Closing, BRI shall hold such cash as agent for the 
Shareholders, and refund such cash to the Shareholders subsequent to Closing.

                             THE MANAGEMENT COMPANY

<PAGE>

                          AGREEMENT AND PLAN OF MERGER


     Agreement entered into as of August 25, 1997 by and among Berkshire 
Realty Company, Inc., a Delaware corporation ("BRI"), The Arborview Management 
Company, a Maryland corporation (the "Management Company"), and the 
stockholders set forth on Schedule 2.2 attached hereto (collectively the 
"Stockholders").  BRI, the Management Company and the Stockholders are 
referred to collectively herein as the "Parties."

     This Agreement contemplates a tax-free merger of the Management Company 
into BRI.  In such merger, the Stockholders will receive capital stock of BRI 
in exchange for their capital stock of the Management Company.

     Now, therefore, in consideration of the representations, warranties and 
covenants herein contained, the Parties agree as follows.


     1.     The Merger.

          1.1    The Merger.  Upon and subject to the terms and conditions of 
this Agreement, the Management Company shall merge with and into BRI (with 
such merger referred to herein as the "Merger") at the Effective Time (as 
defined below). From and after the Effective Time, the separate corporate 
existence of the Management Company shall cease and BRI shall continue as the 
surviving corporation in the Merger (the "Surviving Corporation").  The 
"Effective Time" shall be the time at which BRI and the Management Company 
file the certificate of merger or other appropriate documents prepared and 
executed in accordance with the relevant provisions of the Delaware General 
Corporation Law (the "Certificate of Merger") with the Secretary of State of 
the State of Delaware and the Maryland General Corporation Law with the 
Department of Assessments and Taxation of the State of Maryland.  The Merger 
shall have the effects set forth in Section 259 of the Delaware General 
Corporation Law.

          1.2    The Closing.  The closing of the transactions contemplated by 
this Agreement (the "Closing") shall take place at the offices of Hale and 
Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at such other place 
as the Parties may mutually agree, at 10:00 a.m. local time on a date 
("Closing Date") mutually agreed to in writing by the Parties, but not later 
than October 31, 1997.

          1.3    Actions at the Closing.  At the Closing, (a) the Management 
Company shall deliver to BRI the various certificates, instruments and 
documents referred to in Section 8.10, (b) BRI shall deliver to the Company 
the various certificates, instruments and documents referred to in Section 
9.9, (c) the Management 



                                      -1-
<PAGE>

Company and BRI shall file with the Secretary of State of the State of Delaware
the Certificate of Merger, (d) the Management Company and BRI shall file with
the Department of Assessments and Taxation of the State of Maryland the Articles
of Merger, (e) BRI shall deliver certificates for the BRI Shares (as defined
below) to the Stockholders, and (f) the Stockholders shall deliver certificates
for the Company Shares (as defined below).

          1.4    Additional Action.  BRI may, at any time after the Effective 
Time, take any action, including executing and delivering any document, in the 
name and on behalf of the Management Company, in order to consummate the 
transactions contemplated by this Agreement.

          1.5    Conversion of Shares. 

               (a)     At the Effective Time, by virtue of the Merger and 
without any action on the part of any Party, each share of common stock, no par
value per share, of the Management Company ("Company Shares") issued and
outstanding immediately prior to the Effective Time shall be converted into and
represent the right to receive such number of shares of common stock, $.01 par
value per share, of BRI ("BRI Common Stock") as is equal to one share of BRI
Common Stock multiplied by the Conversion Ratio. The "Conversion Ratio" shall be
determined by dividing (i) the number of shares of BRI Common Stock equal in
value (as such value is determined at the time and in the manner provided herein
below) to $17,500 (the "Consideration Amount"), by (ii) the number of Company
Shares issued and outstanding immediately prior to the Effective Time; provided,
however, with respect to each property set forth on Exhibit 1 attached hereto,
as to which the transactions described in the applicable Related Agreement (as
defined in Section 11.6) have not been closed on or prior to the Closing Date
hereunder (a "Non-Acquired Property"), there shall be a reduction in the
Consideration Amount equal to the Reduction Amount for such property. The
Reduction Amount for each such property shall be equal to (A) .6 multiplied by
the amount of the Management Fees for such property as set forth on Exhibit 1
multiplied by (B) five (5). The shares of BRI Common Stock to be issued to the
holders of the Company Shares are referred to herein as the "BRI Shares."

               (b)     The Parties agree that, for purposes of this Agreement, 
the value of each share of BRI Common Stock ("BRI Share 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 11.5 hereof, provided that in any event the BRI Share 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 Share Value 
(including the Fixed Floor and Fixed Ceiling) will be 




                                      -2-
<PAGE>

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.

               (c)     The Management Company and the Stockholders acknowledge 
and agree that after the execution hereof, the price of the BRI Common Stock 
may increase or decrease in value as the result of market fluctuations prior

      2.     Representations with respect to the Management Company.  The 
Management Company on behalf of itself and each of the Stockholders, severally 
and not jointly, represents and warrants to BRI as follows:

          2.1    Organization.  The Management Company is a corporation duly 
organized, validly existing and in good standing under the laws of the state 
of Maryland.  The Management Company has all requisite power and authority 
(corporate and other) to own its properties, to carry on its business as now 
being conducted, to execute and deliver this Agreement and the agreements 
contemplated herein and to consummate the transactions contemplated hereby and 
thereby to be consummated by it.  The Management Company is duly qualified to 
do business and is in good standing in all other jurisdictions in which the 
failure to be so qualified and in good standing would have a material adverse 
effect on the Management Company's business (a "Material Adverse Effect").  
Such jurisdictions are set forth on Schedule 2.1 attached hereto.

          2.2    Capitalization of the Management Company.  The authorized 
capital stock of the Management Company is as set forth on Schedule 2.2 
attached hereto, including the number of Company Shares outstanding.  Such 
Company Shares are held of record and beneficially owned by the Stockholders 
as set forth on Schedule 2.2 attached hereto.  All of such Company Shares have 
been duly and validly issued, are fully paid and nonassessable and free of all 
preemptive rights and were issued in compliance with applicable federal and 
state securities laws.  There are no outstanding or authorized options, 
warrants, rights, agreements or commitments to which the Management Company is 
a party or which are binding upon the Management Company providing for the 
issuance, disposition or acquisition of any of its capital stock.  There are 
no outstanding or authorized stock appreciation, phantom stock or similar 
rights with respect to the Management Company.  There are no agreements, 
voting trusts, proxies, or understandings with respect to the voting, or 
registration under the Securities Act, of any Company Shares.  

          2.3    Authorization.  The execution and delivery of this Agreement 
and the agreements provided for herein by the Management Company, and the 
consummation by the Management Company of all transactions contemplated hereby 
and thereby to be consummated by it, have been duly authorized by all 
requisite corporate and shareholder action.  This Agreement and all such other 
agreements and obligations entered into and undertaken in connection with the 
transactions contemplated hereby to which the Management Company is a party 
constitute the valid and legally binding obligations of the Management 
Company, enforceable against the Management Company 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.  The execution, delivery and performance by the 



                                      -4-

Management Company of this Agreement and the agreements provided for herein, 
and the consummation by the Management Company of the transactions 
contemplated hereby and thereby, will not, with or without the giving of 
notice or the passage of time or both, (a) violate the provisions of any law, 
rule or regulation applicable to the Management Company; (b) violate the 
provisions of the Certificate of Incorporation or By-laws of the Management 
Company; (c) violate any judgment, decree, order or award of any court, governme
ntal body or arbitrator which would have a Material Adverse Effect; or (d) 
conflict with or result in the breach or termination of any term or provision 
of, or constitute a default under, or cause any acceleration under, or cause 
the creation of any lien, charge or encumbrance upon the properties or assets 
of the Management Company pursuant to, any indenture, mortgage, deed of trust 
or other instrument or agreement to which the Management Company is a party or 
by which the Management Company or any of its properties is or may be bound 
which would have a Material Adverse Effect.  Schedule 2.3 attached hereto sets 
forth a true, correct and complete list of all material consents and approvals 
of third parties that are required in connection with the consummation by the 
Management Company of the transactions contemplated by this Agreement and the 
agreements provided for herein.

          2.4    Assets.  Excluded Assets shall mean all assets of the 
Management Company (including cash attributable to periods prior to the 
Closing) other than (i) the Contracts and (ii) the assets set forth on 
Schedule 2.4 hereto.  The Management Company shall distribute the Excluded 
Assets prior to Closing to the Shareholders. Upon the Closing, the Management 
Company will own all tangible assets set forth on Schedule 2.4 attached 
hereto.

          2.5    Financial Statements.  Attached hereto as Schedule 2.5 are 
unaudited financial statements of the Management Company, including balance 
sheets, statements of operations and statements of partners' capital for the 
fiscal year ended December 31, 1996 (the "December 31 Financial Statements") 
and on or before August 31, 1997 the Management Company shall provide 
unaudited financial statements (the "Current Financial Statements") for the 
six-month period ending June 30, 1997 (the "Balance Sheet Date").  The 
December 31 Financial Statements, the Current Financial Statements and the 
Closing Financial Statement to be delivered pursuant to Section 6.8 are 
collectively referred to as the "Financial Statements".  The Financial 
Statements fairly present the financial condition of the Management Company as 
of the respective statement dates in accordance with generally accepted 
accounting principles consistently applied (except as may be indicated in the 
notes thereto), and reflect all liabilities, fixed, contingent or otherwise, 
required to be disclosed in such Financial Statements in accordance with 
generally accepted accounting principles (subject, in the case of any 
unaudited interim financial statements, to normal year end adjustments).  The 
Financial Statements shall be certified by the Management Company&WP1-9;s 
chief financial officer.

of business after the Balance Sheet Date and not material in amount, either

Management Company or the Stockholders, proceeding or investigation pending or 
threat thereof, against the Management Company or the Stockholders which 
questions the validity of this Agreement or the right of the Management 
Company or the Stockholders to enter into it, or which might result in or 
have, either individually or in the aggregate, a Material Adverse Effect on 
the Management Company.  The Management Company is not in violation of or in 
default with respect to any judgment, order, writ, injunction, decree or rule 
of any court, administrative agency or governmental authority or any 
regulation of any administrative agency or governmental authority except for 
such violations or defaults which would not have a Material Adverse Effect.  

          2.8    Insurance.  Set forth on Schedule 2.8 hereto is a true and 
complete list of all insurance policies of the Management Company (the 
"Insurance Policies") and a list of all presently outstanding claims 
thereunder.  The Management Company has done nothing to reduce or impair the 
insurance afforded by the Insurance Policies.  To the Management Company's 
knowledge, there are no material disputes with underwriters of any such 
Insurance Policies and there are no pending or threatened terminations with 
respect to any of such policies.

          2.9    Change in Financial Condition and Assets.  Except as set 
forth on Schedule 2.9 attached hereto or as contemplated by this Agreement, 
since the Balance Sheet Date, there has been no change which materially and 
adversely affects the business, properties, assets, condition (financial or 
otherwise) or prospects of the Management Company.  Neither the Management 
Company, nor the Stockholders, has any knowledge of any existing or threatened 
occurrence, event or development 


                                      -6-

                    (iii)     To the knowledge of the Management Company and 
the Stockholders, the Management Company is not in breach of or default under

Material Adverse Effect.

               (c)     Except as set forth on Schedule 2.12, the continuation,

Management Company is not in violation of any law, regulation or ordinance 
(including, without limitation, laws, regulations or ordinances relating to

Management Company, along with the position and the annual rate of

material respects in accordance with its terms and each of the Management
Company and the ERISA Affiliates has in all material respects met its
obligations with respect to such Employee Benefit Plan and has made all required
contributions thereto. The Management Company and all Employee Benefit Plans are
in compliance in all material respects with the currently applicable provisions
of ERISA and the Code and the regulations thereunder.

               (c)     There are no investigations by an governmental entity, 
termination proceedings or other claims (except claims for benefits payable in 
the normal operation of the Employee Benefit Plans and proceedings with 
respect to qualified domestic relations orders), suits or proceedings against 
or involving any Employee Benefit Plan or asserting any rights or claims to 
benefits under any Employee Benefit Plan that could give rise to any material 
liability.

               (d)      All the Employee Benefit Plans that are intended to be 
qualified under Section 401(a) of the Code have received determination letters 
from the Internal Revenue Service to the effect that such Employee Benefit 
Plans are qualified and the plans and the trusts related thereto are exempt 
from federal income taxes under Sections 401(a) and 501(a), respectively, of 
the Code, no such determination letter has been revoked and revocation has not 
been threatened, no such Employee Benefit Plan has been amended since the date 
of its most recent determination letter or application therefor in any 
respect, and no act or omission has occurred, that would likely result in a 
revocation of such determination.

               (e)     Neither the Management Company nor any ERISA Affiliate 
has ever maintained an Employee Benefit Plan subject to Section 412 of the 
Code or Title IV of ERISA.

               (f)     At no time has the Management Company or any ERISA 
Affiliate been obligated to contribute to any "multiemployer plan" (as defined 
in Section 4001(a)(3) of ERISA).

               (g)     There are no unfunded obligations under any Employee 
Benefit Plan providing benefits after termination of employment to any 
employee of the Management Company (or to any beneficiary of any such 
employee), including but not limited to retiree health coverage and deferred 
compensation, but excluding continuation of health coverage required to be 
continued under Section 4980B of the Code and insurance conversion privileges 
under state law.

      3.     Representations with respect to the Stockholders.  Each of the 
Stockholders, on behalf of his or her self, severally and not jointly, 
represents and warrants to BRI as follows:

          3.1    Authorization.  Such Stockholder has full power and authority 
to enter into and deliver this Agreement and the other agreements provided for 
herein and to consummate the transactions contemplated hereby and thereby.  
This Agreement and all such other agreements and obligations entered into and 
undertaken in connection with the transactions contemplated hereby constitute 
the valid and legally binding obligations of such Stockholder, enforceable 
against such Stockholder 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.  The execution, delivery 
and performance by such Stockholder of this Agreement and the agreements 
provided for herein, and the consummation by such Stockholder of the 
transactions contemplated hereby and thereby, will not, with or without the 
giving of notice or the passage of time or both, (a) violate the provisions of 
any law, rule or regulation applicable to such Stockholder; (b) violate any 
judgment, decree, order or award of any court, governmental body or 
arbitrator; or (c) conflict with or result in the breach or termination of any 
term or provision of, or constitute a default under, or cause any acceleration 
under, or cause the creation of any lien, charge or encumbrance upon the 
Company Shares of such Stockholder pursuant to, any indenture, mortgage, deed 
of trust or other instrument or agreement to which such Stockholder is a party 
or by which such Stockholder is or may be bound.  Schedule 3.1 attached hereto 
sets forth a true, correct and complete list of all consents and approvals of 
third parties that are required in connection with the consummation by such 
Stockholder of the transactions contemplated by this Agreement.

          3.2    Investment.

               (a)     Such Stockholder is acquiring the BRI Shares 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 Shares except in compliance with the 
registration requirements or exemption provisions of any applicable securities 
laws and in accordance with the terms of the Registration Rights Agreement (as 
defined below).

               (b)     Such Stockholder understands that the BRI Shares to be 
issued to Stockholder 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 reliance on 



                                      -12-
<PAGE>

such exemptions is predicated in part on the accuracy and completeness of the
representations and warranties of such Stockholder.

               (c)     Such Stockholder acknowledges and agrees that, for the 
reasons set forth in paragraphs (a) and (b) above, the BRI Shares may not be 
offered, sold, transferred, pledged, or otherwise disposed of by such 
Stockholder 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 Shares may be made without registration under the Act, 
together with either registration or an exemption under applicable Blue Sky 
Laws, or (iii) upon BRI receiving an opinion of counsel knowledgeable in 
securities law matters (and which opinion and counsel shall be reasonably 
acceptable to 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, such Stockholder must bear the economic risk of an 
investment in the BRI Shares for an indefinite period of time.  Such 
Stockholder acknowledges, represents and agrees that (i) his or her economic 
circumstances are such that he or she is able to bear all risks of the 
investment in BRI and the BRI Shares for an indefinite period of time, 
including the risk of a complete loss of his or her investment in the BRI 
Shares, (ii) he or she has knowledge and experience in financial and business

compliance with the terms of this Agreement by the parties hereto other than 
BRI, the execution and delivery by BRI of this Agreement and all other 
documents and instruments contemplated hereby and the performance by BRI of 
its obligations hereunder and thereunder do not and will not constitute a 
default under, or conflict with or violate, any provision of the Certificate 
of Incorporation or By-Laws of BRI or any other material agreement to which 
BRI is a party or by which BRI is bound. 

          4.2    Annual and Quarterly Reports.  BRI has delivered to the

     9.     Indemnification

               (a)     The Stockholder Indemnity.  In the event the parties 
proceed to Closing, each Stockholder agrees, severally and not jointly, to 
indemnify and hold BRI harmless against and with respect to (i) any loss or 
damage (including reasonable attorney's fees) to BRI subsequent to the Closing 
Date resulting from (A) any inaccuracy in or breach of any representation or 
warranty of the Management Company or of such Stockholder or (B) resulting 
from any breach or default by the Management Company or such Stockholder of 
any obligation of the Management Company or such Stockholder under this 
Agreement or (ii) from liabilities for borrowed money incurred by the 
Management Company prior to the Closing; provided that no Stockholder shall be 
required to indemnify BRI for any amounts in excess of 50% of the fair market 
value of the BRI shares received by such Stockholder as of the date such 
indemnification obligation is satisfied (except for indemnification 
obligations with respect to representations of each of the Stockholders in 
Section 3.2, which shall be limited to 100% of the fair market value as of the 
date such indemnification obligation is satisfied of the BRI Shares received 
by such Stockholder (collectively, the "Cap"); and provided further that to 
the extent any of the Stockholders have any indemnification obligation to BRI, 
the Stockholder may elect to satisfy such indemnification obligation by 
directing BRI to cancel such amount of BRI shares acquired by such Stockholder 
pursuant to this Agreement having a fair market value (measured at the time 
such BRI shares are returned or cancelled) equal to the indemnification 
obligation of such Stockholder.

               (b)     The BRI Partnership's Indemnity.  In the event the 
parties proceed to Closing, BRI agrees to indemnify and hold the Stockholder 
harmless against and with respect to (i) any loss or damage (including 
reasonable attorney's fees) to the Stockholder, subsequent to the Closing 
Date, resulting from (A) any inaccuracy in or breach of any representation or 
warranty of BRI or (B) resulting from any breach or default by BRI of any 
obligation of BRI under this Agreement or (ii) from liabilities of the 
Management Company accruing after the Closing (including liabilities accruing 
after the Closing in connection with employee benefit plans) (except for such 
liabilities resulting from a  breach or default by the Stockholder or the 
Management Company for which BRI is indemnified under Section 9(a) above); 
provided that BRI shall not be required to indemnify any Stockholder under 
Section 9(b)(i) for any amounts in excess of 50% of the fair market value as 
of the date such indemnification obligation is satisfied of the BRI shares 
received by such Stockholder (except for indemnification obligations with 
respect to Section 4.10 which shall be limited to 100% of the fair market 
value as of the date such indemnification obligation is satisfied of the BRI sha
res received by such Stockholder; and



                                      -25-
<PAGE>

                (c)     The indemnification obligations of the Stockholders 
and BRI, respectively, with respect to any representation or warranty, shall 
be limited to claims made prior to the last date of survival thereof set forth 
in Section 14.  No such claim for indemnification shall be deemed due and 
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 BRI nor any of the Stockholders shall have any 
liability for claims made under Section 9(a) or 9(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 9 shall be 
the sole and exclusive remedy after the Closing Date for damages available to 
BRI or the Stockholders 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 
BRI or the Management Company.

               (g)     Each of the Stockholders, the Management Company and 
BRI 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.

               (h)     Promptly after receipt by any party hereto of notice of 
the commencement of any action to which any party is entitled to 
indemnification under this Section 9, such party shall use its best efforts to 
notify each other party hereto in writing of the commencement of such action.  
In case any such action is brought, the Stockholders shall be entitled, but 
shall not be required, to participate in the defense thereof, or the 
Stockholders may elect to take charge of and control the defense of such 
action, provided that the stockholders shall agree to pursue the defense of 
such action or claim in good faith by appropriate actions or proceedings 
promptly taken or instituted and diligently pursued.

     10.     Post-Closing Agreements   

          Intentionally omitted. 

     11.     Termination of Agreement

          11.1   Termination by Lapse of Time.  This Agreement shall terminate 
at 5:00 p.m., Boston time, on October 31, 1997, if the transactions 
contemplated hereby have not been consummated, unless such date is extended by 
the written consent of all of the parties hereto.

          11.2   Termination by Agreement of the Parties.  This Agreement may 
be terminated by the mutual written agreement of the Parties.  In the event of 
such termination by agreement, BRI shall have no further obligation or 
liability to the Management Company and the Stockholders under this Agreement, 
and the Management Company and the Stockholders shall have no further 
obligation or liability to BRI under this Agreement.  

          11.3   Management Company's or Stockholders' Default.  If as of the 
Closing Date, the Management Company or the Stockholders have failed to 
perform all of their respective material obligations under this Agreement, the 
Management Company and the Stockholders shall be in default under this 
Agreement, and BRI shall be entitled to terminate this Agreement by written 
notice given to the Management Company and the Stockholders within seven 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 BRI desires to consummate the Merger in accordance with the 
terms of this Agreement and the Management Company or the Stockholders 
willfully refuse to perform their respective obligations hereunder, BRI, at 
its option, shall have the right to compel specific performance by the 
Management Company and the Stockholders to close the transaction hereunder, in 
which event BRI shall have the right to recover from the Management Company 
and the Stockholders the amount of all reasonable legal fees, court costs and 
other litigation expenses incurred by BRI in connection with the exercise of 
its right of specific performance.

          11.4   BRI's Default.  If as of the Closing Date, BRI has failed to 
perform all of its material obligations under this Agreement, BRI shall be in 
default under this Agreement, and the Management Company shall be entitled to 
terminate this Agreement by written notice given to BRI within seven 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 Management Company desires to consummate the Merger in 
accordance with the terms of this Agreement and BRI 



                                      -27-
<PAGE>

willfully refuses to perform its obligations hereunder, the Management Company,
at its option, shall have the right to compel specific performance by BRI to
close the transaction, in which event the Management Company (and the
Stockholders) shall have the right to recover from BRI the amount of all
reasonable legal fees, court costs and other litigation expenses incurred in
connection with the exercise of their right of specific performance.

          11.5   Public Offering Condition.  BRI has informed the Management 
Company and the Shareholders that in connection with the consummation of the 
various Related Transactions (as defined in Section 11.6 hereof), BRI intends 
to undertake either or both of (i) a public offering of common stock or other 
equity securities of BRI (the "Public Offering"), or (ii) a private placement 
of common stock or other equity securities of BRI (the "Private Placement").  
The Management Company and the Shareholders shall supply any documentation and 
additional information required by BRI in order to complete the offering 
materials in connection with the Public Offering or the Private Placement.  
The obligation of BRI to proceed with the Closing of the transactions 
contemplated by this Agreement is expressly conditioned upon the successful 
completion of the Public Offering and the Private Placement raising a minimum 
of $75,000,000.00.  If the Public Placement and the Private Placement do not 
in the aggregate complete offerings which raise a minimum of $75,000,000 as 
aforesaid prior to the Closing Date hereunder, BRI shall have the right to 
terminate this Agreement effective as of the Closing Date, and, thereafter 
this Agreement shall be void and without recourse to all parties except for 
provisions which are expressly stated to survive termination of this 
Agreement.

          11.6   Related Agreements.  Simultaneously herewith, BRI and 
affiliates of BRI have 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 agreements are more particularly described on Exhibit 4 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 [as such term is 
defined in the Related Agreements] (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, unless such date is 
extended by the written consent of all of the parties hereto, 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, unless such date is extended by the written consent of all of the 
parties hereto, whereupon this Agreement shall be void and without recourse to 
all parties, except for provisions which are expressly 



                                      -28-
<PAGE>

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.

     12.     Brokers/Allocation of Expenses/Apportionments

          12.1   Brokers.  The Parties mutually represent and warrant that 
none 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 Management Company 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 Stockholders and QPI in 
accordance with the provisions of Section 12.3 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 BRI or the 
Management Company have any obligation to pay any commission to APC.

          12.2   Allocation of Transaction Costs.  Each Stockholder hereby 
acknowledges and agrees that a portion of the amount due to such Stockholder 
will be used to pay the fees and expenses attributable to the transaction 
contemplated by this Agreement, which fees and expenses are the several 
obligations of the Stockholder pursuant to the terms of this Agreement.  Each 
Stockholder and the Management Company 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 
Management Company 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 purposes of 
this Section 12.2, each of the Stockholders 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 certain transferor 
partnerships and related entities (collectively, the "Related Entities"), 
which shall be Indirect Costs (ii) to the extent it is determined that APC is 
due any fee as described in Section 12.1 hereof, up to $1,000,000 of such fee 
(which may be paid at Closing or held back in an escrow account by Questar 
Investment Corporation 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 Questar Investment Corporation 
shall also be Indirect Costs.  Each of the Stockholders acknowledges and 
agrees that (i) any and all Direct Costs shall be allocated to each of them 
with respect to their interest in the Management Company and (ii) any and all 
Indirect Costs shall be allocated among 



                                      -29-
<PAGE>

the Stockholders and Related Entities at Closing based on the pro rata number of
BRI shares allocated at Closing to each of them. Each of the Stockholders
further acknowledges and agrees that Questar Investment Corporation shall be
authorized to determine the allocations of the transaction costs and expenses to
be allocated in accordance with the provisions of this Section 12.2.

          12.3   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 cash:

               (a)     prepaid and collected fees received under any of the 
Contracts;

               (b)     wages and pension benefits of all persons employed by 
the Management Company;

               (c)     charges or prepayments under the Contracts; and

               (d)     all other income and expenses relating to the 
Management Company.

     If as of the Closing Date, any items of income or expense attributable to 
the Management Company 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.

     At least five (5) days prior to the Closing Date, the Shareholders and 
BRI shall prepare and exchange preliminary calculations of all adjustments and 
prorations to be made pursuant to this Section 12.3.  The Stockholders and BRI 
shall cooperate in the furnishing of all information and documentation 
necessary to prepare such calculations.

     All cash shall be used by the Management Company to pay all amounts 
payable by the Management Company and any excess, together with all Excluded 
Assets, shall be distributed to the Shareholders prior to Closing, and if any 
of such excess cash applicable to pre-closing periods is not removed from the 
Management Company prior to Closing, BRI shall hold such cash as agent for the 
Shareholders, and refund such cash to the Shareholders subsequent to Closing.

                         REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT, dated as of _________, 1997, by and among 
BERKSHIRE REALTY COMPANY, INC., a Delaware corporation, its subsidiary, 
Berkshire Apartments, Inc. (collectively, the "General Partner"), and each of 
those parties who are or become parties to the Amended and Restated Agreement 
of Limited Partnership of BRI OP Limited Partnership (the "Partnership") dated 
as of _________, 1997, as amended (the "Partnership Agreement"), as limited 
partners of the Partnership from time to time in accordance with the terms of 
the Partnership Agreement (the "Rights Holders").

     A.     Pursuant to the Partnership Agreement, the Rights Holders have the 
right at any time and from time to time to convert all or a portion of their 
units of partnership interest in the Partnership "Partnership Units") into 
shares (the "Shares") of the General Partner's common stock, par value $.01 
per share (the "Common Stock"), or cash, as selected by the General Partner.

     B.     In order to induce the Rights Holders to enter into the 
Partnership Agreement, the General Partner has agreed to provide certain 
registration rights with respect to the Shares as set forth in this Agreement.

     In consideration of the mutual covenants and agreements set forth herein 
and for good and valuable consideration, the receipt of which is hereby 
acknowledged, the parties hereto agree as follows:

     1.   Securities Subject to this Agreement.  The securities entitled to the
benefits of this Agreement are the Shares issued by the General Partner to the 
Rights Holders upon conversion (pursuant to Article XI of the Partnership 
Agreement) of Partnership Units held by such Rights Holders, and any other 
securities issued by the General Partner in exchange 


<PAGE>
for any of such Shares (collectively, the "Registrable Securities" but, with
respect to any particular Registrable Security, only so long as it continues to
be a Registrable Security. Registrable Securities shall include any securities
issued as a dividend or distribution on account of Registrable Securities or
resulting from a subdivision of the outstanding shares of Registrable Securities
into a greater number of shares (by reclassification, stock split or otherwise).
For the purposes of this Agreement, a security that was at one time a
Registrable Security shall cease to be a Registrable Security when (i) such
security has been effectively registered under the Securities Act and such
security has been disposed of pursuant to such registration statement, (ii) such
security is sold, or is capable of being sold, in reliance on Rule 144 (or any
similar provision then in effect) under the Securities Act, (iii) such security
has been otherwise transferred and (a) the General Partner has delivered a new
certificate or other evidence of ownership not bearing the legend set forth on
the Shares upon the initial issuance thereof (or other legend of similar import)
and (b) in the reasonable opinion of counsel to the General Partner, the
subsequent disposition of such security would not require the registration or
qualification under the Securities Act, or (iv) such security has ceased to be
outstanding.

     2. Shelf Registration.

          2.1 Initial Shelf Registration.

               (a)     The General Partner shall file a "shelf" registration 
statement with respect to all Registrable Securities on any appropriate form
pursuant to Rule 415 (or similar rule that may be adopted by the Commission)
under the Act (the "Initial Shelf Registration") on or within two weeks either
side of the date which is one year and ten days after the closing date of the
Questar Transactions (the "Filing Date") (i) covering the issuance of the Common
Stock by the General Partner upon conversion of the Partnership 




                                      -2-
<PAGE>

Units, and (ii) if required by any Rights Holder, the resale of such Rights
Holder's Common Stock issuable upon conversion of the Partnership Units and,
shall use its best efforts to have such Initial Shelf Registration declared
effective by the Commission on or prior to 90 days after the Filing Date.

          (b) The General Partner shall use its best efforts to keep the Shelf
Registration continuously effective until all the Registrable Securities covered
by the Shelf Registration have been sold pursuant to the terms of the Shelf
Registration. 

          The Company further agrees: (i) if requested by any Rights Holder
in connection with any sale by such Rights Holder (other than pursuant to an
underwritten offering), to promptly include in any Initial Shelf Registration or
Demand Shelf Registration Statement (as defined below), as the case may be, and
related prospectus, pursuant to a supplement or post-effective amendment if
necessary, such information as such Rights Holder(s) may reasonably request to
have included therein, including, without limitation, information relating to
the "Plan of Distribution" of the Registrable Securities; and (ii) to make all
required filings of any prospectus supplement or post-effective amendment as
soon as practicable after the Company is notified of the matters to be included
in such prospectus supplement or post-effective amendment. 

          2.2 Shelf Registration Upon Demand. In the event that the General
Partner is unable to perform the obligations set forth in Section 2.1 by reason
of a change in Commission policy or law or circumstances beyond the General
Partner's control, subject to the provisions of Section 2.3, upon the written
request of any Rights Holder at any time requesting that the General Partner
effect the registration rights provided under this Section 2 (the "Request"),
and specifying in the Request the number of Registrable Securities to be
registered and the intended method of disposition thereof, the General Partner
shall 



                                      -3-
<PAGE>

promptly, but in any event within 10 days after receipt of the Request,
give written notice to all other Rights Holders that the General Partner has
received the Request (the "Notice"), and will thereupon use its best efforts to
file within 60 days after receipt of the Request a registration statement (a
"Demand Shelf Registration Statement"), on Form S-3 or other appropriate form
under the Securities Act for an offering to be made on a delayed or continuous
basis pursuant to Rule 415 thereunder or any similar rule that may be adopted by
the Securities and Exchange Commission (the "Commission"), with respect to sales
in ordinary course brokerage or dealer transactions not involving an
underwritten public offering, covering (i) all Registrable Securities held by
the Rights Holder identified in the Request and (ii) all other Registrable
Securities which the General Partner has been requested to register by the
holders thereof by written request delivered to the General Partner within 30
days after the giving of the Notice by the General Partner (which request shall
specify the number of Registrable Securities to be registered and the intended
method of disposition thereof). The General Partner shall use all reasonable
efforts to cause the Demand Shelf Registration Statement to be declared
effective by the commission as soon as practicable after the filing thereof and
to keep the Demand Shelf Registration Statement continuously effective for a
period of two years from the date the Demand Shelf Registration Statement is
declared effective (or such shorter period ending upon the date that all
Registrable Securities initially covered by the Demand Shelf Registration
Statement cease to be Registrable Securities); provided that if the General
Partner shall furnish to the Rights Holders whose Registrable Securities are
covered by such Demand Shelf Registration Statement a certificate signed by the
President of the General Partner stating that, in the good faith judgment of the
Board of Directors of the General Partner, it would be significantly
disadvantageous to the General Partner and its stockholders for any such 


                                      -4-
<PAGE>

Demand Shelf Registration Statement to be filed, amended or supplemented, the
General Partner may defer such filing, amending or supplementing of such Demand
Shelf Registration Statement for a period of not more than 60 days (the "No Sale
Period") and in such event such Rights Holders shall be required to discontinue
disposition of any Registrable Securities covered by such Demand Shelf
Registration Statement during such period, in which case the General Partner
shall extend the period during which such Demand Shelf Registration Statement
shall be maintained effective pursuant to this-Section 2.2 by the number of days
during the No Sale Period.

          2.3 Limitation on Demand Registration Rights. Notwithstanding the
provisions of Section 2.2, the General Partner shall not be obligated to file a
Demand Shelf Registration Statement more often than once during any twelve-month
period. 

     3. Restrictions on Public Sale. In the event the General Partner intends to
issue shares of its capital stock to the public in an underwritten offering,
each of Messrs. Morton Gorn, Stephen M. Gorn and John B. Colvin agrees, if
requested by the managing underwriter or underwriters for such underwritten
offering, not to effect any public sale or distribution of Registrable
Securities or any securities convertible into or exchangeable or exercisable for
such Registrable Securities, including a sale pursuant to Rule 144 (or any
similar provision then in force) under the Securities Act, during the 14 days
prior to, and during the 180-day period beginning on, the effective date of such
underwritten offering (except as part of such underwritten offering). 

     4. Registration Procedures. Whenever a Rights Holder has requested that any
Registrable Securities be registered pursuant to Section 2, the General Partner
shall: 

          (i) use all reasonable efforts to register or qualify such Registrable
Securities under such securities or "blue sky" laws of such jurisdictions as any
Rights Holder


                                      -5-
<PAGE>

identified in the Request reasonably requests in writing, and shall do any and
all other acts and things that may be reasonably necessary or advisable to
register or qualify for sale in such jurisdictions the Registrable securities
owned or to be acquired by such Rights Holder upon conversion of such Rights
Holder's Partnership Units; provided, however, that the General Partner shall
not be required to (a) qualify generally to do business in any jurisdiction
where it is not then so qualified, (b) subject itself to taxation in any such
jurisdiction, (c) consent to general service of process in any such jurisdiction
or (d) provide any undertaking required by such securities or "blue sky" laws or
make any change in its charter or bylaws that the Board of Directors determines
in good faith to be contrary to the best interests of the General Partner and
its stockholders;

          (ii) notify the Rights Holders whose Registrable Securities are
covered by the Initial Shelf Registration or the Demand Shelf Registration
Statement, as the case may be, at any time when a prospectus relating to the
Initial Shelf Registration or the Demand Shelf Registration Statement, as the
case may be, is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such
Initial Shelf Registration or such Demand Shelf Registration Statement, as the
case may be, contains an untrue statement of a material fact or omits to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, and promptly prepare and file with the Commission a supplement
or amendment to such prospectus so that, as thereafter delivered to the
purchasers of such Rights Holders' Registrable Securities, such prospectus will
not contain an untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading; and




                                      -6-
<PAGE>


          (iii) use all reasonable efforts to cause all Registrable Securities
covered by the Initial Shelf Registration or the Demand Shelf Registration
Statement, as the case may be, to be listed on each securities exchange on which
similar securities issued by the General Partner are then listed, provided that
the applicable listing requirements are satisfied.

     The General Partner may require any Rights Holder who is a seller or
prospective seller of Registrable Securities as to which a registration is being
effected to furnish to the General Partner such information regarding the
distribution of such Registrable Securities and other matters as may be required
to be included in the Initial Shelf Registration or the Demand Shelf
Registration Statement, as the case may be.

     Each Rights Holder who is a seller or prospective seller of Registrable
Securities agrees that, upon receipt of any notice from the General Partner of
the happening of any event of the kind described in paragraph (ii) of this
Section 4, such Rights Holder shall forthwith discontinue disposition of
Registrable Securities pursuant to the Initial Shelf Registration or the Demand
Shelf Registration Statement, as the case may be, until such Rights Holder's
receipt of copies of the supplemented or amended prospectus contemplated by
paragraph (ii) of this Section 4 and, if so directed by the General Partner,
such Rights Holder shall deliver to the General Partner all copies of the
prospectus covering such Registrable Securities current at the time of receipt
of such notice. If the General Partner shall give any such notice, the General
Partner shall extend the period during which such Initial Shelf Registration or
such Demand Shelf Registration Statement, as the case may be, shall be
maintained effective pursuant to Section 2 by the number of days during the
period from and including the date of the giving of such notice pursuant to
paragraph (ii) of this Section 4 to and including the date when each Rights
Holder who is a seller or prospective seller of Registrable securities covered
by such Initial Shelf Registration or such Demand


                                      -7-
<PAGE>

Shelf Registration Statement, as the case may be, shall have received the copies
of the supplemented or amended prospectus contemplated by paragraph (ii) of this
Section 4.

     5. Registration Expenses. The General Partner shall pay all expenses
incident to its performance of or compliance with this Agreement, including,
without limitation, (i) all Commission, stock exchange and National Association
of Securities Dealers, Inc., registration, filing, transfer agent and listing
fees, (ii) all fees and expenses incurred in complying with securities or "blue
sky" laws (including reasonable fees and disbursements of counsel in connection
with "blue sky" qualifications of the Registrable Securities), (iii) all
printing, messenger and delivery expenses, and (iv) all fees and disbursements
of the General Partner's independent public accountants and counsel, in each
case, regardless of whether such registration becomes effective, unless such
Initial Shelf Registration or such Demand Shelf Registration Statement, as the
case may be, fails to become effective as a result of the fault of a Rights
Holder; provided, however, that the General Partner shall not pay the costs and
expenses of any Rights Holder relating to selling commissions and discounts
relating to Registrable Securities to be sold by such Rights Holder, brokerage
fees, transfer taxes or the fees or expenses of any counsel, accountants or
other representatives retained by the Rights Holders, individually or in the
aggregate. 


     6. Indemnification; Contribution.

          6.1 Indemnification by the General Partner, The General Partner agrees
to indemnify, to the fullest extent permitted by law, each Rights Holder, its
officers, directors, partners and agents and each person, if any, who controls
such Rights Holder (within the meaning of the Securities Act), against any and
all losses, claims, damages, liabilities and expenses caused by any untrue or
alleged untrue statement of material fact contained in any registration
statement, prospectus or preliminary prospectus or any



                                      -8-
<PAGE>

amendment thereof or supplement thereto or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein (in the case of a prospectus, in light of the
circumstances under which they were made) not misleading, except insofar as the
same are caused by or contained in any information with respect to such Rights
Holder furnished in writing to the General Partner by such Rights Holder
expressly for use therein or by such Rights Holder's failure to deliver a copy
of the prospectus or any supplements thereto after the General Partner has
furnished such Rights Holder with a sufficient number of copies of the same or
by the delivery of prospectuses by such Rights Holder after the General Partner
notified such Rights Holder in writing to discontinue delivery of prospectuses.

     6.2 Indemnification by Rights Holders. In connection with any registration
statement in which a Rights Holder is participating, each such Rights Holder
shall furnish to the General Partner in writing such information and affidavits
with respect to such Rights Holder as the General Partner reasonably requests
for use in connection with any such registration statement or prospectus and
agrees to indemnify, severally and not jointly, to the fullest extent permitted
by law, the General Partner, its officers, directors, partners and agents and
each person, if any, who controls the General Partner (within the meaning of the
Securities Act) against any and all losses, claims, damages, liabilities and
expenses resulting from any untrue or alleged untrue statement of a material
fact or any omission or alleged omission of a material fact required to be
stated in any registration statement, prospectus or preliminary prospectus or
any amendment thereof or supplement thereto or necessary to make the statements
therein (in the case of a prospectus, in light of the circumstances under which
they were made) not misleading, to the extent, but only to the extent, that such
untrue or alleged untrue statement or omission is contained in or omitted



                                      -9-
<PAGE>

from, as the case may be, any information or affidavit with respect to such
Rights Holder so furnished in writing by such Rights Holder.

     6.3 Conduct of Indemnification Proceedings. Any party that proposes to
assert the right to be indemnified under this Section 6 shall, promptly after
receipt of notice of commencement of any action against such party in respect of
which a claim is to be made against an indemnifying party or parties under this
Section 6, notify each such indemnifying party of the commencement of such
action, enclosing a copy of all papers served, but the omission so to notify
such indemnifying party will not relieve it from any liability that it may have
to any indemnified party under the foregoing provisions of this Section 6
unless, and only to the extent that, such omission results in the forfeiture of
substantive rights or defenses by the indemnifying party. If any such action is
brought against any indemnified party and it notifies the indemnifying party of
its commencement, the indemnifying party will be entitled to participate in and,
to the extent that it elects by delivering written notice to the indemnified
party promptly after receiving notice of the commencement of the action from the
indemnified party, jointly with any other indemnifying party similarly notified,
to assume the defense of the action, with counsel reasonably satisfactory to the
indemnified party, and after notice from the indemnifying party to the
indemnified party of its election to assume the defense, the indemnifying party
will not be liable to the indemnified party for any legal or other expenses
except as provided below and except for the reasonable costs of investigation
subsequently incurred by the indemnified party in connection with the defense.
If the indemnifying party assumes the defense, the indemnifying party shall have
the right to settle such action without the consent of the indemnified party;
provided, however, that the indemnifying party shall be required to obtain such
consent (which consent shall not be unreasonably withheld) if the settlement
includes any admission of wrongdoing on the part



                                      -10-
<PAGE>

of the indemnified party or any decree or restriction on the indemnified party
or its officers or directors; provided, further, that no indemnifying party, in
the defense of any such action, shall, except with the consent of the
indemnified party (which consent shall not be unreasonably withheld), consent to
entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability with respect to such action.
The indemnified party will have the right to employ its own counsel in any such
action, but the fees, expenses and other charges of such counsel will be at the
expense of such indemnified party unless (i) the employment of counsel by the
indemnified party has been authorized in writing by the indemnifying party, (ii)
the indemnified party has reasonably concluded (based on advice of counsel) that
there may be legal defenses available to it or other indemnified parties that
are different from or in addition to those available to the indemnifying party,
(iii) a conflict or potential conflict exists (based on advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party), or (iv) the indemnifying
party has not in fact employed counsel to assume the defense of such action
within a reasonable time after receiving notice of the commencement of the
action, in each of which cases the reasonable fees, disbursements and other
charges of counsel will be at the expense of the indemnifying party or parties,
It is understood that the indemnifying party or parties shall not, in connection
with any proceeding or related proceedings in the same jurisdiction, be liable
for the reasonable fees, disbursements and other charges of more than one
separate firm admitted to practice in such jurisdiction at any one time from all
such indemnified party or parties unless (a) the employment of more than one
counsel has been authorized in writing by the




                                      -11-
<PAGE>

indemnifying party or parties, (b) an indemnified party has reasonably concluded
(based on advice of counsel) that there may be legal defenses available to it
that are different from or in addition to those available to the other
indemnified parties, or (c) a conflict or potential conflict exists (based on
advice of counsel to an indemnified party) between such indemnified party and
the other indemnified parties, in each of which cases the indemnifying party
shall be obligated to pay the reasonable fees and expenses of such additional
counsel or counsels. An indemnifying party will not be liable for any settlement
of any action or claim effected without its written consent (which consent shall
not be unreasonably withheld).

         6.4 Contribution. If the indemnification provided for in this Section 6
from the indemnifying party is unavailable to an indemnified party hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
herein, then the indemnifying party, to the extent such indemnification is
unavailable, in lieu of indemnifying such indemnified party, shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party and indemnified parties in
connection with the actions that resulted in such losses, claims, damages,
liabilities or expenses. The relative fault of such indemnifying party and
indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include, subject to the
limitations set forth in



                                      -12-
<PAGE>

Section 6.3, any legal or other fees or expenses reasonably incurred by such
party in connection with any investigation or proceeding.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6.4 were determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person,

     If indemnification is available under this Section 6, the indemnifying
parties shall indemnify each indemnified party to the fullest extent provided in
Section 6.1 and 6.2 without regard to the relative fault of said indemnifying
parties or indemnified party.

     7. Rule 144. The General Partner covenants that it shall use all reasonable
efforts to file the reports required to be filed by it under the Securities
Exchange Act of 1934, as amended, and the rules and regulations of the
commission thereunder (or, if the General Partner ceases to be required to file
such reports, it shall, upon the request of any Rights Holder, make publicly
available other information), and it shall, if feasible, take such further
action as any Rights Holder may reasonably request, all to the extent required
from time to time to enable such Rights Holder to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or (ii) any similar rules or regulations hereafter
adopted by the Commission. Upon the written request of any Rights Holder, the
General Partner shall deliver to such Rights Holder a written statement as to
whether it has complied with such requirements.
