sufficiency of which are hereby acknowledged, the Transferor Partners and the

                                    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

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-


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-



(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-



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-



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-



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-



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-



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

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

(iii) had the opportunity to ask questions of the BRI 



                                      -25-



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

     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, 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

     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

                                      -46-



Partnership 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
M. Gorn and John B. Colvin, or an entity controlled by them, given to the BRI
Partnership pursuant to the Pledge Agreement (described on Schedule K), no
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 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




                                      -47-



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 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.



                                      -48-



     (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.

     10.07 Pre-Closing Obligations of Borrower Corporate General Partner. Prior
to the Closing, the Borrower Corporate General Partner shall deliver the
following to the BRI Partnership (the "Borrower Partnership Closing Documents"):



                                      -49-




     (a) Assignment of Borrower General Partnership Interests. An assignment of

executed and delivered by the Borrower Corporate General Partner, which shall
transfer such Borrower General Partnership Interest in the Borrower Partnership

either at or subsequent to the Closing, deem reasonably necessary in order to




                                      -51-



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 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

     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-



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-



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-



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-



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-



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-



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.

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.

terminate automatically simultaneously with the termination of any such Related
Agreement or upon the failure of all of the other parties to the Related

     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 




                                      -68-



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.

     19.04 Power of Attorney. In consideration of the foregoing matters and
intending to be legally bound hereby, each of the undersigned Transferor
Partners and the Borrower Corporate General Partner 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

fairways affidavits and gap indemnities as are required by the terms of this
Agreement and endorsement, assignment and transfer of the issued and outstanding
stock of the Borrower Corporate General Partner currently owned by the
Transferor Partnership to the Transferor Agent.

     19.05 Time of Effectiveness. The Transferor Partners and the Borrower
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
Agreement, each of 



                                      -69-

Agreement; provided that the indemnity granted under this Section 19.06 shall
not extend to any act of gross negligence or willful malfeasance on the part of

Gorn, Stephen Gorn and John Colvin, individually, and on behalf of all of the
GGC Parties, jointly and severally, hereby release each of the Transferor
