                                     BY-LAWS
                                       of
                         BERKSHIRE REALTY COMPANY, INC.
                      (as amended through October 9, 1997)


                                    ARTICLE I

                                  SHAREHOLDERS

         SECTION 1. Annual Meeting. The annual meeting of shareholders shall be
held on the first Tuesday of May in each year after 1990 (or if that be a legal
holiday in the place where the meeting is to be held, on the next succeeding
full business day) at the principal office of the Corporation in Massachusetts
at ten o'clock a.m., unless a different hour, date or place within or without
the United States is fixed by the Board of Directors, the Chairman of the Board,
if one is elected, or the President. If no annual meeting has been held on the
date fixed as above provided, a special meeting in lieu thereof may be held, and
such special meeting shall have, for the purposes of these By-laws or otherwise,
all the force and effect of an annual meeting.

         SECTION 2. Matters to be Considered at Annual Meeting. At an annual
meeting of shareholders, only such business shall be conducted, and only such
proposals shall be acted upon, as shall have been properly brought before the
annual meeting (a) by, or at the direction of, a majority of the Board of
Directors (unless at the time of such action there is an Interested Shareholder,
in which case the affirmative vote of a majority of the Continuing Directors
then in office shall also be required) or (b) by any shareholder of the
Corporation who complies with the notice procedures set forth in this Section 2.
For a proposal to be properly brought before an annual meeting by a shareholder,
the shareholder must have given timely notice thereof in writing to the
Secretary of the Corporation. To be timely, a shareholder's notice must be
delivered to, or mailed and received at, the principal executive offices of the
Corporation not less than 50 days nor more than 150 days prior to the scheduled
annual meeting, regardless of any postponements, deferrals or adjournments of
that meeting to a later date; provided, however, that if less than 70 days'
notice or prior public disclosure of the date of the scheduled annual meeting is
given or made, notice by the shareholder to be timely must be so delivered or
received not later than the close of business on the 15th day following the day
on which such notice of the date of the scheduled annual meeting was mailed. A
shareholder's notice to the Secretary shall set forth as to each matter the
shareholder proposes to bring before the annual meeting (a) a brief description
of the proposal desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, (b) the name and address, as
they appear on the Corporation's stock transfer books, of the shareholder
proposing such business and of the beneficial owners (if any) of the stock
registered in such shareholder's name and the name and address of other
shareholders known by such shareholder to be supporting such proposal, (c) the
class and number of shares of the Corporation's capital stock


<PAGE>



which are beneficially owned by the shareholder and beneficial owners (if any)
on the date of such shareholder's notice and by any other shareholders known by
such shareholder to be supporting such proposal on the date of such
shareholder's notice, and (d) any financial interest of the shareholder in such
proposal.

         If the Board of Directors determines that any shareholder proposal was
not timely made in accordance with the terms of this Section 2, the Board of
Directors may determine that such shareholder proposal will not be acted upon at
the annual meeting. If the Board of Directors, or a designated committee
thereof, determines that the information provided in a shareholder's notice does
not satisfy the informational requirements of this section in any material
respect, the Secretary of the Corporation shall promptly notify such shareholder
of the deficiency in the notice. The shareholder shall have an opportunity to
cure the deficiency by providing additional information to the Secretary within
such period of time, not to exceed 5 days from the date such deficiency notice
is given to the shareholder, as the Board of Directors or such committee shall
reasonably determine. If the deficiency is not cured within such period, or if
the Board of Directors or such committee determines that the additional
information provided by the shareholder, together with the information
previously provided, does not satisfy the requirements of this Section 2 in any
material respect, then the Board of Directors may determine that such
shareholder proposal will not be acted upon at the annual meeting. If there is
an Interested Shareholder, any determination to be made by the Board of
Directors or a designated committee thereof pursuant to the provisions of this
Section 2 shall also require the concurrence of a majority of the Continuing
Directors then in office. The Secretary of the Corporation shall notify a
shareholder in writing whether his proposal has been made in accordance with the
time and informational requirements of this Section.

         Notwithstanding the procedure set forth in the preceding paragraph, if
neither the Board of Directors nor such committee makes a determination as to
the validity of any shareholder proposal, the presiding officer of the annual
meeting shall determine and declare at the annual meeting whether the
shareholder proposal was made in accordance with the terms of this Section 2. If
the presiding officer determines that a shareholder proposal was made in
accordance with the terms of this Section 2, he shall so declare at the annual
meeting and ballots shall be provided for use at the meeting with respect to any
such proposal. If the presiding officer determines that a shareholder proposal
was not made in accordance with the terms of this Section 2, he shall so declare
at the annual meeting and any such proposal shall not be acted upon at the
annual meeting.

         This provision shall not prevent the consideration and approval or
disapproval at the annual meeting of reports of officers, Directors and
committees of the Board of Directors, but in connection with such reports, no
new business shall be acted upon at such annual meeting unless stated, filed and
received as herein provided.

         SECTION 3. Special Meetings. Special meetings of the shareholders of
the Corporation may be called only in the manner provided in the Restated
Certificate of Incorporation.

         SECTION 4. Matters to be Considered at Special Meetings. Only those
matters set forth in the call of the special meeting may be considered or acted
upon at such special meeting, unless otherwise provided by law.

                                       -2-


<PAGE>



         SECTION 5. Notice of Meetings; Adjournments. A written notice of all
annual meetings of shareholders stating the hour, date and place of such annual
meetings shall be given by the Secretary or an Assistant Secretary (or other
person authorized by these By-laws or by law) not less than 10 days nor more
than 60 days before the meeting, to each shareholder entitled to vote thereat or
to each shareholder who, under the Restated Certificate of Incorporation or
under these By-laws, is entitled to such notice, by delivering such notice to
him or by mailing it, postage prepaid, addressed to such shareholder at the
address of such shareholder as it appears on the Corporation's stock transfer
books. Such notice shall be deemed to be delivered when hand delivered to such
address or deposited in the mail so addressed, with postage prepaid.

         Notice of all special meetings of shareholders shall be given in the
same manner as provided for annual meetings of the shareholders, except that the
written notice of all special meetings shall state the purpose or purposes for
which the meeting has been called.

         Notice of an annual or special meeting of shareholders need not be
given to a shareholder if a written waiver of notice is executed before or after
such meeting by such shareholder or such shareholder's authorized attorney, if
communication with such shareholder is unlawful, or if such shareholder attends
such meetings unless such attendance was for the express purpose of objecting at
the beginning of the meeting to the transaction of any business because the
meeting was not lawfully called or convened. Neither the business to be
transacted at, nor the purpose of, any annual or special meeting of shareholders
need be specified in any written waiver of notice.

         When any annual or special meeting of shareholders is adjourned to
another hour, date or place, notice need not be given of the adjourned meeting
other than an announcement at the meeting at which the adjournment is taken of
the hour, date and place to which the meeting is adjourned; provided, however,
that if the adjournment is for more than 30 days, or if after the adjournment a
new record date is fixed for the adjourned meeting, notice of the adjourned
meeting shall be given as in the case of the original meeting to each
shareholder of record entitled to vote thereat.

         SECTION 6. Quorum. The holders of a majority in interest of all stock
issued, outstanding and entitled to vote, represented in person or by proxy,
shall constitute a quorum at any annual or special meeting of shareholders; but
if less than a quorum is present at a meeting, a majority in interest of the
shareholders present or the presiding officer may adjourn the meeting from time
to time, and the meeting may be held as adjourned without further notice, except
as provided in Section 5 of this Article I. At such adjourned meeting at which a
quorum is present, any business may be transacted which might have been
transacted at the meeting as originally noticed. The shareholders present at a
duly constituted meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum.

         SECTION 7. Voting and Proxies. Shareholders shall have one vote for
each share of stock entitled to vote owned by them of record according to the
books of the Corporation, unless otherwise provided by law or by the Restated
Certificate of Incorporation. Shareholders may vote either in person or by
written proxy, but no proxy shall be voted or acted upon after three years from
its date, unless the proxy provides for a longer period. Proxies shall be filed
with the Secretary of the meeting before being voted. Except as otherwise
limited therein, proxies shall entitle the persons

                                       -3-


<PAGE>



authorized thereby to vote at any adjournment of such meeting, but they shall
not be valid after final adjournment of such meeting. A proxy with respect to
stock held in the name of two or more persons shall be valid if executed by or
on behalf of any one of them unless at or prior to the exercise of the proxy the
Corporation receives a specific written notice to the contrary from any one of
them. A proxy purporting to be executed by or on behalf of a shareholder shall
be deemed valid unless challenged at or prior to its exercise, and the burden of
proving invalidity shall rest on the challenger.

         SECTION 8. Rights of the Series 1997-A Convertible Preferred
Shareholders -

                  (a) Voting - The holders of shares of Series 1997-A
Convertible Preferred Stock have the right to vote on all matters in which the
holders of Common Stock are entitled to vote, including but not limited to the
ability to notice special meetings and to determine the subject matter thereof,
on an "as converted" basis with holders of shares of Common Stock, as though
part of the same class as holders of Common Stock, with such number of shares of
Common Stock deemed held of record by holders of shares of Series 1997-A
Convertible Preferred Stock on any Record Date as would be the number of shares
of Common Stock into which the shares of Series 1997-A Convertible Preferred
Stock held by such holder would be entitled to be converted on such Record Date.
Notwithstanding the foregoing, as set forth in the Certificate of Designation
with respect to the Series 1997-A Convertible Preferred Stock, with respect to
votes as to directors, merger or consolidation, the issuance of any shares of
Series 1997-A Convertible Preferred Stock, the exchange or conversion of any
shares of Series 1997-A Convertible Preferred Stock or the amendment, alteration
or repeal of any provision of the Corporation Charter, the Certificate of
Designation providing for the preferences and rights of the holders of shares of
Series 1997-A Convertible Preferred Stock, the Agreement of Limited Partnership
of the Operating Partnership, or any organizational document of any Subsidiary,
in such a manner as would affect adversely the preferences, conversion or other
rights, voting powers, restrictions, limitations as to dividends and other
distributions, qualifications and terms and conditions of redemption of the
Series 1997-A Convertible Preferred Stock, the holders of Series 1997-A
Convertible Preferred Stock must approve such action as a class by an
affirmative vote of not less than a majority of the outstanding shares of Series
1997-A Convertible Preferred Stock.

                  (b) Notices - The holders of shares of Series 1997-A
Convertible Preferred Stock will receive all notice of meetings of the holders
of shares of Common Stock, and all other notices and correspondence to the
holders of shares of Common Stock provided by the Corporation, and will be
entitled to take such actions, and have such rights, as are set forth in the
Certificate of Designation or are otherwise available to the holders of shares
of Common Stock in the Charter and in the Bylaws of the Corporation as are in
effect on the execution date, in each case with the same effect as would be
taken by holders of Series 1997-A Convertible Preferred Stock if deemed to be
holders of such number of shares of Common Stock as determined as aforesaid.

                  (c) Resolutions - The Resolutions of the Board of Directors
relating to the issuance of the 2,737,000 shares of Series 1997-A Convertible
Preferred Stock are hereby adopted in the form attached.


                                       -4-


<PAGE>



         SECTION 9. Action at Meeting. When a quorum is present, any matter
before any annual or special meeting of shareholders shall be decided by vote of
the holders of a majority of the shares of stock voting on such matter, except
where a larger vote is required by law, by the Restated Certificate of
Incorporation or by these By-laws. Any election by shareholders shall be
determined by a plurality of the votes cast, except where a larger vote is
required by law, by the Restated Certificate of Incorporation or by these
By-laws. The Corporation shall not directly or indirectly vote any shares of its
own stock except as to shares which it holds in a fiduciary capacity or except
as otherwise permitted by law. An abstention shall not be deemed a vote cast.

         SECTION 10. No Action by Consent. Any action required or permitted to
be taken by the shareholders of the Corporation must be effected at a duly
constituted annual or special meeting of such holders and may not be effected by
any consent in writing by such shareholders.

         SECTION 11. Stockholder Lists. The Secretary or an Assistant Secretary
(or the Corporation's transfer agent or other person authorized by these By-laws
or by law) shall prepare and make, at least 10 days before every annual or
special meeting of shareholders, a complete list of the shareholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each shareholder and the number of shares registered in the name of each
shareholder. Such list shall be open to the examination of any shareholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least 10 days prior to the meeting, either at a place within the city
where the meeting is to be held, which place shall be specified in the notice of
the meeting, or, if not so specified, at the place where the meeting is to be
held. The list shall also be produced and kept at the hour, date and place of
the meeting during the whole time thereof, and may be inspected by any
shareholder who is present.

         SECTION 12. Presiding Officer. The presiding officer at all annual or
special meetings of shareholders shall have the power, among other things, to
adjourn such meeting at any time and from time to time, subject to Sections 5
and 6 of this Article I. The order of business and all other matters of
procedure at any meeting of the shareholders shall be determined by the
presiding officer.

                                   ARTICLE II

                                    DIRECTORS

         SECTION 1. Powers. All the power of the Corporation shall be exercised
by or under the direction of the Board of Directors except as otherwise provided
by the Restated Certificate of Incorporation or required by law.

         SECTION 2.  Number, Terms and Independent Directors.

         (a) Except as otherwise fixed pursuant to the provisions of the
Restated Certificate of Incorporation relating to the rights of the holders of
any class or series of stock having a preference over the common stock as to
dividends or upon liquidation to elect additional Directors, the number of
Directors of the Corporation shall be fixed by resolution duly adopted from time
to time by the Board of Directors; provided, however, that if at the time of
such action there is an Interested

                                       -5-


<PAGE>



Shareholder, such action shall also require a majority vote of the Continuing
Directors then in office. The Directors, other than those who may be elected by
the holders of any class or series of stock having a preference over the common
stock as to dividends or upon liquidation, shall be classified, with respect to
the time for which they severally hold office, into three classes, as nearly
equal in number as possible as determined by the Board of Directors, with one
class to be elected annually.

         (b) The initial Directors of the Corporation shall hold office as
follows: the first class of Directors shall hold office initially for a term
expiring at the annual meeting of shareholders to be held in 1991, the second
class of Directors shall hold office initially for a term expiring at the annual
meeting of shareholders to be held in 1992, and the third class of Directors
shall hold office initially for a term expiring at the annual meeting of
shareholders to be held in 1993, with the members of each class to hold office
until their respective successors are elected and qualified. Directors elected
at each annual meeting of the shareholders of the Corporation shall hold office
for a term expiring at the annual meeting of shareholders held in the third year
following the year of their election and until their respective successors are
elected and qualified.

         The holders of shares of Series 1997-A Convertible Preferred Stock,
voting as a separate class, shall be entitled at all times to elect one director
(as defined in the Certificate of Designation, the "Series 1997-A Preferred
Director") to the Board of Directors (the "Board") of the Company. In the event
that the Series 1997-A Preferred Director is unable to attend any meeting of the
Board for any reason, then such Series 1997-A Preferred Director may designate,
in writing, one person (the "Observer") who shall have the right to attend, but
not vote at, such meeting. The Observer shall not be deemed to be a member of

         SECTION 3. Director Nominations. Nomination of candidates for election
as Directors of the Corporation at any annual meeting of shareholders may be
made (a) by, or at the direction of, a majority of the Board of Directors
(unless at the time of such action there is an Interested Shareholder, in which
case the affirmative vote of a majority of the Continuing Directors shall also
be required) provided that, a person meeting the requirements of an Independent
Director, as that term is defined in Section 2(c) of this Article II, shall be
nominated by, or at the direction of, the Board of Directors as necessary in
order to maintain a majority of Independent Directors on the Board of Directors,
or (b) by any shareholder entitled to vote at such annual meeting. Only persons
nominated in accordance with the procedures set forth in this Section 3 shall be
eligible for election as Directors at an annual meeting of shareholders.

         Nominations, other than those made by, or at the direction of, the
Board of Directors (and by the Continuing Directors, if required), shall be made
pursuant to timely notice in writing to the Secretary of the Corporation as set
forth in this Section 3. To be timely, a shareholder's notice shall be delivered
to, or mailed and received at, the principal executive office of the Corporation
not less than 60 days nor more than 150 days prior to the date of the scheduled
annual meeting, regardless of postponements, deferrals, or adjournments of that
meeting to a later date; provided, however, that if less than 70 days' notice or
prior public disclosure of the date of the scheduled annual meeting is given or
made, notice by the shareholder to be timely must be so delivered or received
not later than the close of business on the 10th day following the earlier of
(a) the day on which such notice of the date of the scheduled annual meeting was
mailed or (b) the day on which such public disclosure was made. Such
shareholder's notice shall set forth (a) as to each person whom the shareholder
proposes to nominate for election or re-election as a Director (i) the name,
age, business address and residence address of such person, (ii) the principal
occupation or employment of such person, (iii) the class and number of shares of
the Corporation's capital stock which are beneficially owned by such person on
the date of such shareholder notice, and (iv) any other information relating to
such person that is required to be disclosed in solicitations of proxies with
respect to nominees for election as directors, pursuant to Regulation 14A
promulgated by the Securities and Exchange Commission under the Securities
Exchange Act of 1934, as amended (or any subsequent provisions replacing such
Act or the rules and regulations promulgated thereunder); and (b) as to the
shareholder giving the notice (i) the name and address, as they appear on the
Corporation's stock transfer books, of such shareholder and of the beneficial
owners (if any) of the stock registered in such shareholder's name and the name
and address of other shareholders known by such shareholder to be supporting
such nominees, and (ii) the class and number of shares of the Corporation's
capital stock which are beneficially owned by such shareholder and beneficial
owners (if any) on the date of such shareholder notice and by any other
shareholders known by such shareholder to be supporting such nominees on the
date of such shareholder notice. At the request of the Board of Directors, any
person nominated by, or at the direction of, the Board of Directors for election
as a Director at an annual meeting shall furnish to the Secretary of the
Corporation that information required to be set forth in a shareholder's notice
of nomination which pertains to the nominee.

         No person shall be elected by the shareholders as a Director of the
Corporation unless nominated in accordance with the procedures set forth in this
Section 3. Election of Directors at the annual meeting need not be by written
ballot, unless otherwise provided by the Board of Directors or presiding officer
at such annual meeting. If written ballots are to be used, ballots bearing the

                                       -7-


<PAGE>



names of all the persons who have been nominated for election as Directors at
the annual meeting in accordance with the procedures set forth in this Section 3
shall be provided for use at the annual meeting.

         The Board of Directors may reject any nomination by a shareholder not
timely made in accordance with the requirements of this Section 3. If the Board
of Directors, or a designated committee thereof, determines that the information
provided in a shareholder's notice does not satisfy the informational
requirements of this Section 3 in any material respect, the Secretary of the
Corporation shall promptly notify such shareholder of the deficiency in the
notice. The shareholder shall have an opportunity to cure the deficiency by
providing additional information to the Secretary within such period of time,
not to exceed 5 days from the date such deficiency notice is given to the
shareholder, as the Board of Directors or such committee shall reasonably
determine. If the deficiency is not cured within such period, or if the Board of
Directors or such committee reasonably determines that the additional
information provided by the shareholder, together with the information
previously provided does not satisfy the requirements of this Section 3 in any
material respect, then the Board of Directors may reject such shareholder's
nomination. The Secretary of the Corporation shall notify a shareholder in
writing whether his nomination has been made in accordance with the time and
informational requirements of this Section 3.

         Notwithstanding the procedure set forth in the preceding paragraph, if
neither the Board of Directors nor such committee makes a determination as to
the validity of any nominations by a shareholder, the presiding officer of the
annual meeting shall determine and declare at the annual meeting whether a
nomination was made in accordance with the terms of this Section 3. If the
presiding officer determines that a nomination was made in accordance with the
terms of this Section 3, he shall so declare at the annual meeting and ballots
shall be provided for use at the meeting with respect to such nominee. If the
presiding officer determines that a nomination was not made in accordance with
the terms of this Section 3, he shall so declare at the annual meeting and such
nomination shall be disregarded. If there is an Interested Shareholder, any
determinations to be made by the Board of Directors or a designated committee
thereof pursuant to the provisions of this Section 3 shall also require the
concurrence of a majority of the Continuing Directors then in office.

         SECTION 4. Qualification. No Director need be a shareholder of the
Corporation. Unless waived by a vote of the Board of Directors, no individual
may serve as a Director of the Corporation if he has reached the age of 72 years
at the time of election.

         SECTION 5. Vacancies. Any vacancy occurring on the Board of Directors,
including any vacancy created by reason of an increase in the number of
Directors, may be filled in the manner provided in the Restated Certificate of
Incorporation.

         SECTION 6. Removal. Any Director may be removed from office in the
manner provided in the Restated Certificate of Incorporation.

         SECTION 7. Resignation. A Director may resign at any time by giving
written notice to the Chairman of the Board, if one is elected, the President or
the Secretary. A resignation shall be effective upon receipt, unless the
resignation otherwise provides.

<PAGE>



         SECTION 8. Regular Meetings. The regular annual meeting of the Board of
Directors shall be held, without other notice than this By-law, on the same date
and at the same place as the annual meeting of shareholders following the close
of such meeting of shareholders. Other regular meetings of the Board of
Directors may be held at such hour, date and place as the Board of Directors may
by resolution from time to time determine without other notice than such
resolution.

         SECTION 9. Special Meetings. Special meetings of the Board of Directors
may be called, orally or in writing, by or at the request of a majority of the
Directors, the Chairman of the Board, if one is elected, or the President. The
person calling any such special meeting of the Board of Directors may fix the
hour, date and place thereof.

         SECTION 10. Notice of Meetings. Notice of the hour, date and place of
all special meetings of the Board of Directors shall be given to each Director
by the Secretary or an Assistant Secretary, or in case of the death, absence,
incapacity or refusal of such persons, by the Chairman of the Board, if one is
elected, or the President or such other officer designated by the Chairman of
the Board, if one is elected, or the President. Notice of any special meeting of
the Board of Directors shall be given to each Director in person or by telephone
or by telegram sent to his business or home address at least 24 hours in advance
of the meeting, or by written notice mailed to his business or home address at
least 48 hours in advance of the meeting. Such notice shall be deemed to be
delivered when hand delivered to such address, read to such Director by
telephone, deposited in the mail so addressed, with postage thereon prepaid if
mailed, or when delivered to the telegraph company if sent by telegram.

         When any Board of Directors meeting, either regular or special, is
adjourned for more than 30 days, notice of the adjourned meeting shall be given
as in the case of an original meeting. It shall not be necessary to give any
notice of the hour, date or place of any meeting adjourned for 30 days or less
or of the business to be transacted at such meeting, other than an announcement
at the meeting at which such adjournment is taken of the hour, date and place to
which the meeting is adjourned.

         A written waiver of notice executed before or after a meeting by a
Director and filed with the records of the meeting shall be deemed to be
equivalent to notice of the meeting. The attendance of a Director at a meeting
shall constitute a waiver of notice of such meeting, except where a Director
attends a meeting for the express purpose of objecting at the beginning of the
meeting to the transaction of any business because such meeting is not lawfully
called or convened. Except as otherwise required by law, by the Certificate of
Incorporation or by these By-laws, neither the business to be transacted at, nor
the purpose of, any meeting of the Board of Directors need be specified in the
notice or waiver of notice of such meeting.

         SECTION 11. Quorum. At any meeting of the Board of Directors, a
majority of the Directors then in office shall constitute a quorum for the
transaction of business, but if less than a quorum is present at a meeting, a
majority of the Directors present may adjourn the meeting from time to time, and
the meeting may be held as adjourned without further notice, except as provided
in Section 10 of this Article II. Any business which might have been transacted
at the meeting as originally noticed may be transacted at such adjourned meeting
at which a quorum is present.

         SECTION 12. Action at Meeting. At any meeting of the Board of Directors
at which a quorum is present, a majority of the Directors present may take any
action on behalf of the Board of Directors, unless otherwise required by law, by
the Restated Certificate of Incorporation or by these By-laws.

         SECTION 13. Action by Consent. Any action required or permitted to be
taken at any meeting of the Board of Directors may be taken without a meeting if
all members of the Board of Directors consent thereto in writing. Such written
consent shall be filed with the records of the meetings of the Board of
Directors and shall be treated for all purposes as a vote at a meeting of the
Board of Directors.

         SECTION 14. Manner of Participation. Members of the Board of Directors
or of committees elected by the Board pursuant to Section 15 of this Article II
may participate in meetings of the Board or of such committees by means of
conference telephone or similar communications equipment by means of which all
Directors participating in the meeting can hear each other, and participation in
a meeting in accordance herewith shall constitute presence in person at such
meeting for purposes of these By-laws.

         SECTION 15. Committees. The Board of Directors, by the affirmative vote
of a majority of the Directors then in office, may elect from its number
Directors to serve on one or more committees, including an Audit Committee, and
may delegate thereto some or all of its powers except those which by law, by the
Restated Certificate of Incorporation or by these By-laws, may not be delegated.
Except as the Board of Directors may otherwise determine, any such committee may
make rules for conduct of its business, but unless otherwise provided by the
Board of Directors or in such rules, its business shall be conducted so far as
possible in the same manner as is provided by these By-laws for the Board of
Directors. All members of such committees shall hold such offices at the
pleasure of the Board of Directors, except that members of the Audit Committee
shall be Independent Directors and shall serve on such Audit Committee as long
as they are Directors of the Corporation. The Board of Directors may abolish any
such committee, other than the Audit Committee, at any time. Any committee to
which the Board of Directors delegates any of its powers or duties shall keep
records of its meetings and shall report its action to the Board of Directors.
The Board of Directors shall have power to rescind any action of any committee,
other than the Audit Committee, but no such rescission shall have retroactive
effect. With approval of the Board of Directors, the Chief Executive Officer may
appoint such other committees consisting of such Directors as the Chief
Executive Officer shall select. Any recommendations of such committees appointed
by the Chief Executive Officer shall be submitted to the Board of Directors.

         The Series 1997-A Preferred Director shall sit as he may request on
each committee of the Board or on any other group so acting, whether or not
formally constituted as a committee of the Board; provided, however, that the
Series 1997-A Preferred Director shall not have the right to request to sit on
the Executive Committee. The Executive Committee shall report to the full Board
on any matters exceeding $50,000,000.

         SECTION 16. Compensation of Directors. Directors shall receive such
compensation for their services as shall be determined by a majority of the
Board of Directors, provided that Directors who are serving the Corporation as

shall not receive any salary or other compensation for their services as
Directors of the Corporation.

Corporation shall hold office until the regular annual meeting of the Board of
Directors following the next annual meeting of shareholders and until his
successor is elected and qualified or until his earlier resignation or removal.
Election or appointment of an officer, employee or agent shall not of itself
create contract rights. The Board of Directors may, however, authorize the
Corporation to enter into an employment contract with any officer in accordance
with law, but no such contract right shall impair the right of the Board of
Directors to remove any officer at any time in accordance with Section 6 of this

the affirmative vote of a majority of the Continuing Directors then in office
shall also be required, and, provided further that, if an officer is to be
removed for cause, he may only be removed after reasonable notice and an

                                      -13-

before such certificate is issued, it may be issued by the Corporation with the
same effect as if he were such officer, transfer agent or registrar at the time
of its issue. Every certificate for shares of stock which are subject to any
restriction on transfer and every certificate issued when the Corporation is
authorized to issue more than one class or series of stock shall contain such

                                 INDEMNIFICATION

         SECTION 1. Right to Indemnification. Each person who was or is made a
party or is threatened to be made a party to or is otherwise involved in any
action, suit or proceeding, whether civil, criminal, administrative,
investigative or otherwise (hereinafter a "Proceeding"), by reason of the fact
that he or she is or was (a) a Director of the Corporation, (b) an officer of
the Corporation elected or appointed by the shareholders or the Board of
Directors, or (c) serving, at the request of the Corporation as evidenced by a
vote of the Board of Directors prior to the occurrence of the event to which the
indemnification relates, as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan (such persons
described in (a), (b) and (c) are sometimes hereinafter referred to as an
"Indemnitee"), whether the basis of such Proceeding is alleged action in an
official capacity as such a Director or officer of the Corporation or as such
other director, officer, employee or agent or in any other capacity while
serving as such a Director or officer of the Corporation or as such other
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than permitted prior
thereto), against all expense, liability and loss (including, but not limited
to, attorneys' fees, judgments, fines, ERISA excise taxes or penalties and
amounts paid in settlement) reasonably incurred or suffered by such Indemnitee
in connection therewith and such indemnification shall continue as to an
Indemnitee who has ceased to be such a director, officer, employee or agent and
shall inure to the benefit of the Indemnitee's heirs, executors and
administrators; provided, however, that, except as provided in Section 3 of this
Article V with respect to Proceedings to enforce rights to indemnification, the
Corporation shall indemnify any such Indemnitee in connection with a Proceeding
(or part thereof) initiated by such Indemnitee only if such Proceeding (or part
thereof) was authorized or ratified by the Board of Directors of the
Corporation. The right to indemnification conferred in this Article V shall be a
contract right and shall include the right to be paid by the Corporation the
expenses incurred in defending any Proceeding in advance of its final
disposition (hereinafter an "Advancement of Expenses"); provided, however, that,
if the Delaware General Corporation Law requires, an Advancement of Expenses
incurred by an Indemnitee in his or her capacity as a Director or officer of the
Corporation (but not in any other capacity in which service was or is rendered
by such Indemnitee, including, without limitation, service to an employee
benefit plan) shall be made only upon delivery to the Corporation of an
undertaking (hereinafter an "Undertaking"), by or on behalf of such Indemnitee,
to repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is no further right to appeal (hereinafter a
"Final Adjudication") that such Indemnitee is not entitled to be indemnified for
such expenses under this Article V or otherwise.

         SECTION 2. Indemnification of Employees and Agents of the Corporation.
The Corporation may, to the extent authorized from time to time by the Board of
Directors, grant rights to indemnification, and to an Advancement of Expenses,
to any employee or agent of the Corporation to the fullest extent of the
provisions of this Article V.

                                      -15-

         SECTION 3. Right of Indemnitee to Bring Suit. If a claim under this
Article V is not paid in full by the Corporation within sixty days after a
written claim has been received by the Corporation, except in the case of a
claim for an Advancement of Expenses, in which case the applicable period shall
be twenty days, the Indemnitee may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim. If the Indemnitee is
successful in whole or in part in any such suit, or in a suit brought by the
Corporation to recover an Advancement of Expenses pursuant to the terms of an
Undertaking, the Indemnitee shall also be entitled to be paid the expense of
prosecuting or defending such suit. In any suit brought by the Indemnitee to
enforce a right to indemnification hereunder (but not in a suit brought by the
Indemnitee to enforce a right to an Advancement of Expenses), it shall be a
defense that the Indemnitee has not met the applicable standard of conduct set
forth in the Delaware General Corporation Law. In addition, in any suit by the
Corporation to recover an Advancement of Expenses pursuant to the terms of an
Undertaking, the Corporation shall be entitled to recover such expenses upon a
Final Adjudication that the Indemnitee has not met the applicable standard of
conduct set forth in the Delaware General Corporation Law. Neither the failure
of the Corporation (including its Board of Directors, independent legal counsel,
or shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the Indemnitee is proper in the circumstances
because the Indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or
shareholders) that the Indemnitee has not met such applicable standard of
conduct, shall create a presumption that the Indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to
enforce a right to indemnification or to an Advancement of Expenses hereunder,
or by the Corporation to recover an Advancement of Expenses pursuant to the
terms of an Undertaking, the burden of proving that the Indemnitee is not
entitled to be indemnified, or to such Advancement of Expenses, under this
Article V or otherwise shall be on the Corporation.

         SECTION 4. Non Exclusivity of Rights. The rights to indemnification and
to Advancement of Expenses conferred in this Article V shall not be exclusive of
any other right which any person may have or hereafter acquire under these
By-laws, the Restated Certificate of Incorporation or any statute, agreement,
vote of shareholders or disinterested directors or otherwise.

         SECTION 5. Insurance. The Corporation may maintain insurance, at its
expense, to protect itself and any Director, officer, employee or agent of the
Corporation or any director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any expense,
liability or loss, whether or not the Corporation would have the power to
indemnify such person against such expense, liability or loss under the Delaware
General Corporation Law.

                                   ARTICLE VI

                            MISCELLANEOUS PROVISIONS

         SECTION 1. Fiscal Year. The fiscal year of the Corporation shall end on
December 31 of each year.

                                      -16-

         SECTION 2. Seal. The Board of Directors shall have power to adopt and
alter the seal of the Corporation.

         SECTION 3. Execution of Instruments. All deeds, leases, transfers,
contracts, bonds, notes and other obligations to be entered into by the
Corporation in the ordinary course of its business without Director action may
be executed on behalf of the Corporation by the Chairman of the Board, if one is
elected, the President or the Treasurer or any other officer, employee or agent
of the Corporation as the Board of Directors may authorize.

         SECTION 4. Voting of Securities. Unless the Board of Directors
otherwise provides, the Chairman of the Board, if one is elected, the President
or the Treasurer may waive notice of and act on behalf of this Corporation, or
appoint another person or persons to act as proxy or attorney in fact for this
Corporation with or without discretionary power and/or power of substitutions at
any meeting of shareholders or shareholders of any other corporation or
organization, any of whose securities are held by this Corporation.

         SECTION 5. Registered Agent. The Board of Directors may appoint a
registered agent upon whom legal process may be served in any action or
proceeding against the Corporation.

         SECTION 6. Corporate Records. The original or attested copies of the
Restated Certificate of Incorporation, By-laws and records of all meetings of
the incorporators, shareholders and the Board of Directors and the stock
transfer books, which shall contain the names of all shareholders, their record
addresses and the amount of stock held by each, may be kept outside the State of
Delaware and shall be kept at the principal office of the Corporation, at the
office of its counsel or at an office of its transfer agent or at such other
place or places as may be designated from time to time by the Board of
Directors.

         SECTION 7. Definitions. As used in these By-laws, the terms "Interested
Shareholder" and "Continuing Director" shall have the same respective meanings
assigned to them in the Restated Certificate of Incorporation. The term

ownership of securities under these By-laws shall be made in the manner
specified in the Restated Certificate of Incorporation. For purposes herein, the
term "Interested Shareholder" shall not include holders of shares of Series
1997-A Convertible Preferred Stock.

         SECTION 8. Restated Certificate of Incorporation. All references in
these By-laws to the Restated Certificate of Incorporation shall be deemed to
refer to the Restated Certificate of Incorporation of the Corporation, as
amended and in effect from time to time.

         SECTION 9. Amendments. These By-laws may be altered, amended or
repealed, or new By-laws may be adopted, by the Board of Directors or the
shareholders in the manner provided in the Restated Certificate of Incorporation
of the Corporation; provided, however, with respect to Article I, Section 8,
Article II, Section 2(b) and Section 15, Article VI, Section 7 or Section 9, or
any other provisions of these By-laws pertaining to the holders of shares of
Series 1997-A Convertible Preferred Stock, the rights of the holders of shares
of Series 1997-A Convertible Preferred Stock shall not be altered, amended or
repealed, and new By-laws that alter, amend or repeal the rights of the holders
of Series 1997-A Convertible Preferred Stock shall not be adopted without the
affirmative vote of the holders of not less than a majority of the outstanding
shares of Series 1997-A Convertible Preferred Stock.

                 Designating 2,737,000 shares of Preferred Stock
                             as 2,737,000 shares of
                      Series 1997-A CONVERTIBLE PREFERRED STOCK
                           (par value $0.01 per share)

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware


         Berkshire Realty Company, Inc., a corporation organized and existing
under the laws of Delaware (the "Corporation"), does hereby certify that:

         Pursuant to the authority contained in Article IV of the Restated
Certificate of Incorporation of the Corporation, as amended (the "Charter"), and
in accordance with the provisions of Section 151 of the General Corporation Law
of the State of Delaware (the "DGCL"), the Board of Directors of the Corporation
duly adopted the following resolution creating a series of the Preferred Stock,
par value $.01 (the "Preferred Stock"), designated as Series 1997-A Convertible
Preferred Stock:

                  RESOLVED, that a series of the class of authorized Preferred
Stock, par value $.01, of the Company be hereby created, and that the
designation and amount thereof and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such series,
and the qualifications, limitations and restrictions thereof are as follows:

         Section 1.  Designation, Amount and Price.

                  Of the 60,000,000 authorized shares of Preferred Stock,
2,737,000 shares are designated Series 1997-A Convertible Preferred Stock (the
"Series 1997-A Convertible Preferred Stock").

         Section 2.  Dividends and Distributions.

                  (a) Holders of shares of Series 1997-A Convertible Preferred
Stock will be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available for the payment of dividends,
cumulative quarterly cash dividends (rounded up to the nearest whole cent) equal
to the greater of (i) 2.25% of $25.00 per share (such $25.00, the "Stated
Value"), and (ii) the per share Common Stock Dividend Amount, payable in each
case in arrears on February 15, May 15, August 15 and November 15 of each year,
commencing on the first such day after the issuance of a share of Series 1997-A
Convertible Preferred Stock (each a "Dividend Payment Date"). The "Common Stock
Dividend Amount" applicable as of any Dividend Payment Date shall mean the
amount which is the product of (i) the dollar amount of the dividend paid per
share of Common Stock on the dividend payment date with respect to the shares of
Common Stock (other than a distribution payable solely in shares of Common
Stock) which occurs on such Dividend Payment Date or, if no such dividend
payment date occurs on such Dividend Payment Date, the dividend payment date
with respect to the shares of Common Stock next preceding such Dividend Payment
Date and (ii) the number of shares of Common Stock into which each share of
Series 1997-A Convertible Preferred Stock is entitled to be converted, at the
Conversion Price then in effect and otherwise as set forth in this Certificate
of Designation, as of the record date established for such Dividend Payment Date
(determined, for purposes of this computation, to the fourth decimal place).
Such dividends will accrue daily on the basis of a 360-day year of twelve 30-day
months, and will, to the extent not paid in full on a Dividend Payment Date,
compound quarterly at a rate of 2.25% per quarter, whether or not the
Corporation has earnings or surplus. The dividend payable to a holder of a share
of Series 1997-A Convertible Preferred Stock on the first Dividend Payment Date
after the share is issued will be the accrued dividend calculated from the day
the share is issued to such


<PAGE>

Dividend Payment Date. If any Dividend Payment Date is not a Business Day, the
dividend due on that Dividend Payment Date will be paid on the Business Day
immediately succeeding that Dividend Payment Date. Each Dividend Payment Date
will be on a date which is the date fixed for payment of dividends with respect
to the shares of Common Stock or is not more than five Business Days after the
date fixed for payment of dividends with respect to the shares of Common Stock.
As used with regard to the Series 1997-A Convertible Preferred Stock, the term
"Business Day" means a day on which both state and federally chartered banks in
New York, New York are required to be open for general banking business, and all
accrued and compounded dividends together with all accrued but not yet due
dividends (whether or not declared or authorized) are referred to as "Accrued
Dividends."

                  (b) Each dividend will be payable to holders of record of the
Series 1997-A Convertible Preferred Stock on a date (a "Record Date") selected
by the Board of Directors which is not less than 10 nor more than 45 days before
the Dividend Payment Date on which the dividend is to be paid. No Record Date
will precede the close of business on the date the Record Date is fixed.

                  (c) Unless and until all Accrued Dividends on the Series
1997-A Convertible Preferred Stock under Section 2(a) through the last preceding
Dividend Payment Date have been paid, the Corporation may not (i) declare or pay
any dividend, make any distribution (other than a distribution payable solely in
shares of Common Stock), or set aside any funds or assets for payment or
distribution with regard to any Junior Shares (as herein defined), (ii) redeem
or purchase (directly or through the Operating Partnership or Subsidiaries), or
set aside any funds or other assets for the redemption or purchase of, any
Junior Shares or (iii) authorize, take or cause or permit to be taken any action
of the general partner of the Operating Partnership, that will result in (A) the
declaration or payment by the Operating Partnership (defined below) of any
distribution to its partners (other than distributions made concurrently with
distributions payable to the Corporation in respect of its partnership interest
that will be used by the Corporation to fund the payment of dividends on the
Series 1997-A Convertible Preferred Stock (such distributions to the Corporation
being referred to as "Authorized LP Distributions")), or set aside any funds or
assets for payment of any distributions to its partners (other than those made
concurrently with Authorized LP Distributions) or (B) the redemption or purchase
(directly or through the Operating Partnership or Subsidiaries), or the setting
aside of any funds or other assets for the redemption or purchase of, any
partnership interests in the Operating Partnership, except for conversions of
partnership interests in the Operating Partnership in the ordinary course into
shares of Common Stock. As used with regard to the Series 1997-A Convertible
Preferred Stock, the term "Junior Shares" means all shares of Common Stock and
all shares of any other class or series of stock of the Corporation to which the
shares of Series 1997-A Convertible Preferred Stock are prior in rank with
regard to payment of dividends or payments upon the liquidation, dissolution or
winding-up of the Corporation; the term "Operating Partnership" means BRI OP
Limited Partnership, a Delaware limited partnership, or any successor thereto;
and the term "Subsidiary" means any Person in which the Company directly or
indirectly owns any equity interest. As used herein, "Person" shall mean an
individual, partnership, corporation, limited liability company, business trust,
joint stock company, trust, unincorporated association, joint venture, nation or
government, any state or other political subdivision thereof and any entity
exercising executive, legislative, judicial, regulatory or administrative
functions of or pertaining to government or other entity of whatever nature.

                  (d) While any shares of Series 1997-A Convertible Preferred
Stock are outstanding, the Corporation may not pay any dividend, or set aside
any funds for the payment of a dividend, with regard to any shares of any class
or series of stock of the Corporation which ranks on a parity with Series 1997-A
Convertible Preferred Stock as to payment of dividends unless at least a
proportionate payment is made with regard to all Accrued Dividends on the Series
A Convertible Preferred Stock (except, as to any shares of the Series 1997-A
Convertible Preferred Stock as to which a notice of conversion has been
furnished by the holder thereof, at the effective time of conversion). A payment
of dividends with regard to the Series 1997-A Convertible Preferred Stock will
be proportionate to a payment of a dividend with regard to another class or
series of stock if the dividend per share of Series 1997-A Convertible Preferred
Stock is the same percentage of the Accrued Dividends (except as aforesaid) with
regard to a share of Series 1997-A Convertible Preferred Stock that the dividend
paid with regard to a share of stock of the other class or series is of the
Accrued Dividends (except as aforesaid) with regard to a share of stock of that
other class or series.

                  (e) Any dividend paid with regard to shares of Series 1997-A
Convertible Preferred Stock will be paid equally with regard to each outstanding
share of Series 1997-A Convertible Preferred Stock, except to the extent that

                                        2

<PAGE>

shares of Series 1997-A Convertible Preferred Stock are outstanding for
differing amounts of time during the relevant dividend period.

of the same class as holders of Common Stock, with such number of shares of
Common Stock deemed held of record by holders of shares of Series 1997-A
Convertible Preferred Stock on any Record Date as would be the number of shares

Preferred Stock if deemed to be holders of such number of shares of Common Stock

upon the Current Market Price, as defined in Section 5(e)(viii) of this
Certificate of Designation) (i) outstanding (assuming for this purpose the

occurrence of any event, or both, have such effect.

                  (d) The holders of shares of Series 1997-A Convertible
Preferred Stock, voting as a separate class, shall be entitled at all times and
at any time to elect one director (the "Series 1997-A Preferred Director") to
the Board of Directors of the Corporation (the "Board"); provided, however, that
the size of the Board shall not be increased above nine at any time unless
Westbrook Real Estate Fund II, L.P. shall be entitled to elect or appoint that
number of directors to such expanded Board that will permit ERISA counsel to
Westbrook Real Estate Fund II, L.P. to

                                        4

confirm that Westbrook Berkshire Holdings, L.L.C.'s investment in the Series
1997-A Convertible Preferred Stock will continue to qualify as a "venture
capital investment" under the plan asset rules and regulations promulgated under
and the provisions of the Employee Retirement Income Security Act of 1974, as
amended, or any successor thereto. The Series 1997-A Preferred Director, who has
been elected by the Board and agreed to serve until his successor is elected and
qualified, is Paul D. Kazilionis, who shall be considered a "third class"
director in accordance with Article II, Section 2(b) of the Bylaws of the
Corporation (as amended to the date hereof), and who shall sit as he may request
on each committee of the Board (other than the executive committee of the Board)
or on any other group so acting, whether or not formally constituted as a
committee of the Board. In the event that the Series 1997-A Preferred Director
is unable to attend any meeting of the Board for any reason, then such Series
1997-A Preferred Director may designate, in writing, one person (the "Observer")
who shall have the right to attend, but not vote at, such meeting. The Observer
shall not be deemed to be a member of the Board of Directors and shall have none
of the rights, duties, privileges or powers of a member of the Board of
Directors, including, without limitation, the right to notice of or to vote at
meetings of the Board of Directors, and shall not be counted as a member of the
Board of Directors for the purpose of determining whether a quorum is present at
any meeting of the Board of Directors. The Series 1997-A Preferred Director from
time to time sitting as a member of the Board may be removed by the holders of
record of not less than a majority of the outstanding shares of Series 1997-A
Convertible Preferred Stock and, if so removed, a successor individual to serve
as the Series 1997-A Preferred Director may be appointed by the holders of
record of not less than a majority of the outstanding shares of Series 1997-A
Convertible Preferred Stock. At any annual meeting of the holders of Common
Stock at which "third class" directors are to be elected, the incumbent Series
1997-A Preferred Director shall be nominated and, upon the affirmative vote of
not less than a majority of the holders of shares of Series 1997-A Convertible
Preferred Stock, shall be elected to serve as the Series A Preferred Director.
Upon the occurrence of a "Preferred Default" (defined below), (i) the number of
members of the entire Board (as if there were no vacancies or unfilled
newly-created directorships thereon) shall be automatically increased such that
the holders of the Series 1997-A Convertible Preferred Stock shall be entitled
to elect, when considered with the Series 1997-A Preferred Director, a number of
directors of the Corporation equivalent to the smallest number representing a
majority of the number of members of the entire Board as if there were no
vacancies or unfilled newly created directorships on such Board, and (ii) the
holders of shares of Series 1997-A Convertible Preferred Stock, voting as a
separate class, shall be entitled, at each annual meeting of stockholders of the
Corporation and at each special meeting of stockholders of the Corporation
called for the election of directors by the holders of Series 1997-A Convertible
Preferred Stock, to elect a number of directors of the Corporation equivalent to
the smallest number representing a majority of the number of members of the
entire Board as if there were no vacancies or unfilled newly created
directorships on such Board. As used herein, "Preferred Default" shall mean a
failure by the Corporation on any four consecutive Dividend Payment Dates to pay
in full the dividends due and payable on such dates such that there are Accrued
Dividends (whether or not declared) with respect to such four consecutive
Dividend Payment Dates. Whenever the holders of shares of Series 1997-A
Convertible Preferred Stock have the right under this Section 3(d) to elect a
director or directors, but have not done so, the Secretary of the Corporation
will, upon the written request of the holders of record of at least 25% of the
outstanding shares of Series 1997-A Convertible Preferred Stock, call a special
meeting of the holders of Series 1997-A Convertible Preferred Stock for the
purpose of removing and/or electing a director or directors, as the case may be.
The meeting will be held at the earliest practicable date upon the notice
required for annual meetings of the shareholders of the Corporation (or such
shorter notice as is stipulated in the written requests for such meeting or is
otherwise agreed in writing by the holders of record of the outstanding shares
of Series 1997-A Convertible Preferred Stock before or within 10 days after the
meeting) at the place specified in the request for a meeting, or if there is
none, at a place in New York, New York, designated by the Secretary of the
Corporation. If the meeting has not been called within 2 days after delivery of
the written request to the Secretary of the Corporation, or within 4 days after
the request is mailed by registered mail, addressed to the Secretary of the
Corporation at the Corporation's principal office, the holders of record of at
least 25% of the outstanding shares of Series 1997-A Convertible Preferred Stock
may designate in writing one holder to call and appoint an individual to chair
(who need not be an officer or member of the Board) the meeting at the expense
of the Corporation, and the meeting may be called by that person upon the notice
required for annual meetings (or such shorter notice as aforesaid). Any holder
of shares of Series 1997-A Convertible Preferred Stock or its representative
will have access to the stock ledger of the Corporation relating to the Series
1997-A Convertible Preferred Stock for the purpose of causing a meeting of
shareholders to be called in accordance with this Section 3(d). Except as
otherwise provided above in this Section 3(d), a director elected in accordance
with this Section

                                        5

3(d) will serve until the next annual meeting of the shareholders of the
Corporation and until his or her successor is elected and qualified by the
holders of Series 1997-A Convertible Preferred Stock.

          Section 4. Change of Control; Liquidation.

                  (a) Upon (i) the Transfer in a single transaction, or series
of transactions, of all or substantially all of the assets of the Corporation,
the Operating Partnership and the Subsidiaries, considered as a whole, including
for such purpose the assets of any Subsidiary (except that with respect to any
such Subsidiary in which the Corporation or the Operating Partnership has a
direct or indirect minority interest such that a sale, transfer or assignment is
not within the Corporation's or Operating Partnership's control, and is not a
part of, or occurring in connection with, a transaction or series of
transactions covered hereby, this provision shall not apply), (ii) the merger or
consolidation of the Corporation or the Operating Partnership with any other
Person (other than a merger of the Corporation with or into a wholly-owned
Subsidiary of the Corporation in which the Corporation Market Capitalization is
unchanged), (iii) any recapitalization of the Corporation, the Operating
Partnership and the Subsidiaries, considered as a whole, in a single transaction
or a series of transactions, in an amount or amounts which aggregate 50% or more
of Corporation Market Capitalization or (iv) a Change of Control (as defined
herein), the holders of the Series 1997-A Convertible Preferred Stock, may at
their option receive, and, if so electing by written notice to the Corporation
to such effect, will be entitled to receive, out of the assets of the
Corporation available for distribution to its stockholders, whether from
capital, surplus or earnings, before any distributions made to holders of any
Junior Shares, an amount per share (the "Change of Control Preference") equal to
the product of (A) 115% and (B) the sum of (1) Stated Value plus (2) the per
share amount of Accrued Dividends with regard to the Series 1997-A Convertible
Preferred Stock to the date of final distribution (whether or not declared). For
the purposes of this Section 4(a), Corporation Market Capitalization shall be
calculated on the date of the first of any transactions in a series for purposes
of determining the percentage thereof represented by all transactions in such
series. There shall be excluded from transactions as a result of which the
holders of Series 1997-A Convertible Preferred Stock are entitled to elect and
receive the Change of Control Preference (i) the public market trading of shares
of Common Stock in unsolicited transactions, and (ii) the sale of Common Stock
or other securities of the Corporation in underwritten, widely distributed
offerings. The Corporation shall provide proper notice to each holder of record
of shares of Series 1997-A Convertible Preferred Stock of any event of the
nature set forth in clauses (i) to (iv) of this Section 4(a).

                  (b) In the event of a voluntary or an involuntary liquidation,
dissolution or winding-up of the Corporation (including, without limitation, the
Plan of Liquidation (as defined in the Certificate of Amendment of the
Corporation dated December 7, 1990, included in the Charter), the holders of the
Series 1997-A Convertible Preferred Stock, may at their option receive, and, if
so electing by written notice to the Corporation to such effect, shall be
entitled to receive, out of the assets of the Corporation available for
distribution to its stockholders, whether from capital, surplus or earnings,
before any distributions made to holders of any Junior Shares, an amount per
share as set forth in this Section 4(b) as a liquidation preference (the
"Liquidation Preference") in the manner and as provided in Section 4(a), except
that the Liquidation Preference shall be at an amount per share equal to the
Liquidation Percentage (as defined and established below) multiplied by the sum
of (i) Stated Value plus (ii) the per share amount of Accrued Dividends with
respect to the Series 1997-A Convertible Preferred Stock to the date of final
distribution (whether or not declared). As used herein, the "Liquidation
Percentage" shall for the periods specified mean the percentage specified as set
forth in the following table:

Notwithstanding the foregoing, upon the liquidation, dissolution or winding-up
of the Corporation solely and directly as a result of the adoption and
implementation of the Plan of Liquidation (as defined in the Certificate of
Amendment of the Corporation dated December 7, 1990, included in the Charter),
holders of shares of Series 1997-A Convertible Preferred Stock which vote in
favor of the adoption of the Plan of Liquidation shall be entitled to receive
the Liquidation Percentage measured as if such Plan of Liquidation was adopted
after the seventh anniversary of the initial issuance of Series 1997-A
Convertible Preferred Stock, regardless of the date on which such Plan of
Liquidation was actually adopted.

                  (c) Holders of Series 1997-A Convertible Preferred Stock may
further elect, when delivering the written notice to the Corporation with
respect to the election under Section 4(a) or Section 4(b), in lieu of receiving
the Change of Control Preference or the Liquidation Preference, as the case may
be, to receive Common Stock on conversion of Series 1997-A Convertible Preferred
Stock, without regard to the time restriction on conversion established in the
first sentence of Section 5(a) of this Certificate of Designation, in the manner
and as provided in Section 5 of this Certificate of Designation.

                  (d) If, upon any liquidation, dissolution or winding-up of the
Corporation, the assets of the Corporation, or proceeds of those assets,
available for distribution to the holders of Series 1997-A Convertible Preferred
Stock and of shares of all other classes or series which are on a parity as to
distributions on liquidation with the Series 1997-A Convertible Preferred Stock
are not sufficient to pay in full the Change of Control Preference or the
Liquidation Preference, as the case may be, to the holders of the Series 1997-A
Convertible Preferred Stock who have not elected to convert such stock pursuant
to Section 4(c) and any liquidation preference of all other classes or series
which are on a parity as to distributions on liquidation with the Series 1997-A
Convertible Preferred Stock, then the assets, or the proceeds of those assets,
which are available for distribution to such holders of shares of Series 1997-A
Convertible Preferred Stock and of the shares of all other classes or series
which are on a parity as to distributions on liquidation with such Series 1997-A
Convertible Preferred Stock will be distributed to the holders of the Series
1997-A Convertible Preferred Stock and of the shares of all other classes or
series which are on a parity as to distributions on liquidation with the Series
1997-A Convertible Preferred Stock ratably in accordance with the respective
amounts of the liquidation preferences of the shares held by each of them. After
payment of the full amount of the Change of Control Preference or the
Liquidation Preference, as the case may be, such holders of shares of Series
1997-A Convertible Preferred Stock will not be entitled to any further
distribution of assets of the Corporation.

                  As used herein, a "Change of Control" of the Corporation or
the Operating Partnership shall be deemed to have occurred if any of the
following occur (or, in the case of any proposal, if any of the following could
occur as a result thereof): (i) the Corporation takes or fails to take any
action such that it ceases to be required to file reports under Section 13 of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any
successor to that Section; (ii) any "person" (as defined in Sections 13(d) and
14(d) of the Exchange Act) becomes the "beneficial owner" (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of either (A) 20% or more
of the outstanding shares of Common Stock, or (B) 20% (by right to vote or grant
or withhold any approval) of the outstanding securities of any other class or
classes which individually or together have the power to elect a majority of the
members of the Board; (iii) the Board determines to recommend, or fails to
determine to recommend, the acceptance of any proposal set forth in a tender
offer statement or proxy statement filed by any person with the Securities and
Exchange Commission which indicates the intention on the part of that person to

                                        7

<PAGE>

acquire, or acceptance of which would otherwise have the effect of that person
acquiring, either (A) 20% or more of the outstanding shares of the Common Stock,
or (B) 20% (by right to vote or grant or withhold any approval) of the
outstanding securities of any other class or classes which individually or
together have the power to elect a majority of the members of the Board; (iv)
other than as a result of the death or disability of one or more of the
directors within a three-month period, and other than by reason of the holders
of Series 1997-A Convertible Preferred Stock exercising voting rights as set
forth in Section 3(d) of the Certificate of Designation, a majority of the
members of the Board for any period of three consecutive months are not persons
who (A) had been directors of the Corporation for at least the preceding 24
consecutive months or (B) when they initially were elected to the Board, (x)
were nominated (if they were elected by the stockholders) or elected (if they
were elected by the directors) with the affirmative concurrence of 66-2/3% of
the directors who were Continuing Directors at the time of the nomination or
election by the Board and (y) were not elected as a result of an actual or
threatened solicitation of proxies or consents by a person other than the Board
or an agreement intended to avoid or settle such a proxy solicitation (the
directors described in clauses (A) and (B) of this subsection (iv) being
"Continuing Directors"); (v) the Corporation or a Subsidiary of the Corporation
ceases to be the sole General Partner of the Operating Partnership or grants or
sells to any person, or consents to any amendment to the agreement of limited
partnership of the Operating Partnership, or the organizational documents of the
other Subsidiaries, which has the effect of transferring, the power to control
or direct the actions of the Operating Partnership or such other Subsidiaries as
if such person (A) is a general partner of the Operating Partnership or (B) is a
limited partner of the Operating Partnership with consent or approval rights
greater than the consent or approval rights held by the limited partners of the
Operating Partnership on the date hereof; or (vi) the Operating Partnership is a
party to any entity conversion or any merger or consolidation in which the
Operating Partnership is not surviving entity in such merger or consolidation or
in which the effect is of the nature set forth in the next preceding clause (v).

          Section 5. Conversion Into Common Stock.

                  (a) Optional Conversion. (i) On and after September 19, 1998,
or earlier than September 19, 1998 as provided in Section 4(c), each holder of
shares of Series 1997-A Convertible Preferred Stock will have the right, at the
holder's option, exercised by notice to such effect (the "Notice of Election to
Convert"), to convert all or any of the shares of Series 1997-A Convertible
Preferred Stock held of record by the holder into shares of Common Stock, such
that each share of Series 1997-A Convertible Preferred Stock will be entitled to
be converted into (A) a number of fully paid and non-assessable shares of Common
Stock (calculated as to each conversion to the nearest 1/100th of a share) equal
to Stated Value plus the amount, if any, of the per share amount of Accrued
Dividends as of the effective time of the conversion, divided by the Conversion
Price, as defined below, then in effect, or (B) such other securities or assets
as the holder is entitled to receive in accordance with Section 5(e).

                        (ii) The holder of each share of Series 1997-A 
Convertible Preferred Stock to be converted must surrender the certificate
representing that share to the conversion agent for the Series 1997-A
Convertible Preferred Stock appointed by the Corporation (which may be the
Corporation itself), with the Notice of Election to Convert on the back of that
certificate duly completed and signed, at the principal office of the conversion
agent. If the shares issuable on conversion are to be issued in a name other
than the name in which the Series A Convertible Preferred Stock is registered,
each share surrendered for conversion must be accompanied by an instrument of
transfer, in form reasonably satisfactory to the Corporation, duly executed by
the holder or the holder's duly authorized attorney and by funds in an amount
sufficient to pay any transfer or similar tax which is required to be paid in
connection with the transfer or evidence that such tax has been paid or is not
payable.

                  (b) Mandatory Conversion. Subject to Section 7 of this
Certificate of Designation, if, after the fifth anniversary of the date of the
first issuance of shares of Series 1997-A Convertible Preferred Stock, the
closing price of the Common Stock on each of at least 20 Trading Days (as
defined herein) (including the Trading Day immediately before both the Notice of
Mandatory Conversion and the Mandatory Conversion Date referred to below) of the
preceding period of 30 consecutive Trading Days immediately prior to the Notice
of Mandatory Conversion and the Mandatory Conversion Date shall be greater than
the Conversion Price in effect on each of such 20 Trading Days, the Corporation
shall have the right, subject to the rights of the holders under Section 3(d), 4
and 7 of this Certificate of Designation, to convert at any time and from time
to time not less than 500,000 of the outstanding shares of Series 1997-A
Convertible Preferred Stock into a number of shares of Common Stock (calculated

                                        8

<PAGE>

as to each conversion to the nearest 1/100th of a share) equal to the product of
(i) the number of shares of Series 1997-A Convertible Preferred Stock to be
converted multiplied by (ii) the Stated Value plus the amount, if any, of the
per share amount of Accrued Dividends, with regard to the Series 1997-A
Convertible Preferred Stock to the date of conversion (whether or not declared),
divided by the Conversion Price then in effect, such that each share of Series
1997-A Convertible Preferred Stock is valued as set forth in clause (ii) in
consideration for Common Stock issued in conversion priced at the Conversion
Price calculated in accordance with Section 5(e) of this Certificate of
Designation. In order to elect to effect the mandatory conversion of Series
1997-A Convertible Preferred Stock, subject to the requirement as to closing
price preceding the Mandatory Conversion Date, set forth above, the Corporation
shall issue a notice as to the date of the intended conversion and number of
shares of Series 1997-A Convertible Preferred Stock which are to be converted
into shares of Common Stock (the "Notice of Mandatory Conversion") to all
holders of outstanding shares of Series A Convertible Preferred Stock on a date
(the "Mandatory Conversion Notice Date") at least 90 but not more than 120 days
prior to the conversion date specified in the Notice of Mandatory Conversion
(the "Mandatory Conversion Date"), which Notice of Mandatory Conversion
specifies a record date (the "Mandatory Conversion Record Date") selected by the
Board of Directors which is not less than 20 more than 45 days before the
Mandatory Conversion Date on which the conversion is to occur. If the number of
shares of Series 1997-A Convertible Preferred Stock to be converted into shares
of Common Stock on a Mandatory Conversion Date is less than all of the
outstanding shares of Series 1997-A Convertible Preferred Stock, then the number
of shares of each holder of Series A Convertible Preferred Stock, as held of
record by each such holder on the Mandatory Conversion Record Date, which will
be converted into shares of Common Stock will be that number of shares of Series
1997-A Convertible Preferred Stock rounded to the nearest ten shares, which is
equal to the proportion of all outstanding shares of Series 1997-A Convertible
Preferred Stock on such Mandatory Conversion Record Date held of record by such
holder of Series 1997-A Convertible Preferred Stock to the total number of such
shares outstanding. Such number of shares of each holder of Series 1997-A
Convertible Preferred Stock which are to be converted, if less than all
outstanding shares of Series 1997-A Convertible Preferred Stock are included in
the Notice of Mandatory Conversion, will be set forth (with the computation used
in making such determination as to each holder of Series 1997-A Convertible
Preferred Stock) in the Notice of Mandatory Conversion. If the Corporation gives
a Notice of Mandatory Conversion, then, provided that the computation set forth
in the Notice of Mandatory Conversion is not clearly erroneous, the number of
the outstanding shares of Series 1997-A Convertible Preferred Stock which are
the subject of such Notice of Mandatory Conversion will be automatically
converted into shares of Common Stock at the close of business on the Mandatory
Conversion Date regardless of whether the holders of such shares of Series
1997-A Convertible Preferred Stock actually surrender the certificates
representing their shares of Series 1997-A Convertible Preferred Stock for
conversion. At the close of business on the Mandatory Conversion Date, (i) the
certificates representing the shares of Series 1997-A Convertible Preferred
Stock will cease to represent anything other than the shares of Common Stock
into which the shares of the Series 1997-A Convertible Preferred Stock were
automatically converted and the shares of Series 1997-A Convertible Preferred
Stock which were not automatically converted and (ii) the Corporation shall, at
its option (the exercise of which will be described in the Notice of Mandatory
Conversion), either (A) deliver certificates representing the shares of Common
Stock to which the holders of the Series 1997-A Convertible Preferred Stock are
entitled without requiring the surrender of the certificates which formerly
represented shares of Series 1997-A Convertible Preferred Stock, or (B) deliver
certificates representing (1) the shares of Common Stock to which the holders of
Series 1997-A Convertible Preferred Stock are entitled and (2) the shares of
Series 1997-A Convertible Preferred Stock continued to be held by the holders of
Series 1997-A after giving effect to such conversion, when the holder surrenders
the certificates representing Series 1997-A Convertible Preferred Stock issued
before the Mandatory Conversion Date and complies with the other requirements of
subparagraph 5(a)(ii) (excluding the completion of the Notice of Election to
Convert).

                  (c) Conversion Procedures. (i) The effective time of the
conversion under Section 5(a) shall be immediately prior to the close of
business on the day when all the conditions in Section 5(a)(ii) have been
satisfied. The effective time of the conversion under Section 5(b) shall,
subject to the rights of holders under Sections 3(d), 4 and 7, be the close of
business on the Mandatory Conversion Date.

                        (ii) If shares are surrendered between the close of 
business on a dividend payment Record Date and the opening of business on the
corresponding Dividend Payment Date ("Ex Record Date Shares"), the dividend with
respect to those shares will be payable on the Dividend Payment Date to the
holder of record of the Ex Record Date Shares on the dividend payment Record
Date notwithstanding the surrender of the Ex Record

                                        9

<PAGE>

Date Shares for conversion after the dividend payment Record Date and prior to
the Dividend Payment Date. The Corporation will make no payment or adjustment
for Accrued Dividends on Ex Record Date Shares, whether or not in arrears, or
for dividends on the shares of Common Stock issued upon conversion of the Ex
Record Date Shares, other than to make payment to the holder of record thereof
on the Record Date. The provisions of this Section 5(c)(ii) shall not limit the
obligation of the Corporation to issue shares of Common Stock in conversion of
shares of Series 1997-A Convertible Preferred Stock, including Ex Record Date
Shares, at Stated Value plus Accrued Dividends (whether or not declared), as
elsewhere provided in this Certificate of Designation.

                       (iii) Except as otherwise permitted in clause (ii)(B) of
the last sentence of Section 5(b), as promptly as practicable after the
effective time for conversion of shares of Series 1997-A Convertible Preferred
Stock, the Corporation will issue and will deliver to the holder at the office
of the holder set forth in the Notice of Election to Convert, or on the holder's
written order, a certificate or certificates representing the number of full
shares of Common Stock issued upon the conversion of the shares of Series 1997-A
Convertible Preferred Stock. Any fractional interest in respect of a share of
Common Stock arising upon a conversion will be settled as provided in Section
5(d).

                        (iv) Each conversion will be deemed to have been 
effected at the effective time provided in Section 5(c)(i), and the person in
whose name a certificate for shares of Common Stock is (or, in the case of a
conversion of less than all shares of Series 1997-A Convertible Preferred Stock
pursuant to Section 5(b), in whose name certificates for shares of Common Stock
and Series 1997-A Convertible Preferred Stock are) to be issued upon a
conversion will be deemed to have become the holder of record of the shares of
Common Stock represented by that certificate at such effective time. All shares
of Common Stock delivered upon conversion of Series 1997-A Convertible Preferred
Stock will upon delivery be duly and validly issued and fully paid and
nonassessable, free of all liens and charges and not subject to any preemptive
rights except such preemptive rights as may exist pursuant to the Stock Purchase
Agreement dated as of September 19, 1997, among the Company and Westbrook
Berkshire Holdings, L.L.C., and its affiliates. The shares of Series 1997-A
Convertible Preferred Stock so converted will no longer be deemed to be
outstanding and all rights of the holder with respect to those shares will
immediately terminate, except the right to receive the shares of Common Stock,
the shares of Series 1997-A Convertible Preferred Stock not converted on a
Mandatory Conversion Date, and, if applicable, other securities, cash or other
assets to be issued or distributed as a result of the conversion.

                  (d) Fractional Shares. No fractional shares of Common Stock
will be issued upon conversion of shares of Series 1997-A Convertible Preferred
Stock. Any fractional interest in a share of Common Stock resulting from
conversion of shares of Series 1997-A Convertible Preferred Stock will be paid
in cash (computed to the nearest cent) based on the Current Market Price (as
herein defined) of the Common Stock on the Trading Date next preceding the date
of conversion. If more than one share of Series 1997-A Convertible Preferred
Stock is surrendered for conversion at substantially the same time by the same
holder, the number of full shares of Common Stock issuable upon the conversion
will be computed on the basis of all the shares of Series 1997-A Convertible
Preferred Stock surrendered at that time by that holder.

                  (e) Conversion Price. The "Conversion Price" per share of
Series 1997-A Convertible Preferred Stock will initially be a price (the
"Initial Conversion Price") equal to $12.125, unless adjusted pursuant to
Section 5(e)(xi), and will be further adjusted as follows from time to time,
subject to Section 5(e)(ix), if any of the events described below occurs:

                         (i) If the Corporation (A) pays a dividend or makes a
distribution on its Common Stock in shares of its Common Stock or (B)
subdivides, splits or reclassifies its outstanding Common Stock into a greater
number of shares, the Conversion Price in effect immediately prior to that event
will be reduced so that the holder of a share of Series 1997-A Convertible
Preferred Stock surrendered for conversion after that event will receive the
number of shares of Common Stock which the holder would have received if the
share of Series 1997-A Convertible Preferred Stock had been converted
immediately before the happening of the event (or, if there is more than one
such event, if the share of Series 1997-A Convertible Preferred Stock had been
converted immediately before the first of those events and the holder had
retained all the Common Stock or other securities or assets received after the
conversion). If the Corporation combines its outstanding Common Stock into a
smaller number of shares, the

                                       10

<PAGE>

Conversion Price in effect immediately prior to that event will be increased so
that the holder of a share of Series 1997-A Convertible Preferred Stock
surrendered for conversion after that event will receive the number of shares of
Common Stock which the holder would have received if the shares of Series 1997-A
Convertible Preferred Stock had been converted immediately before the happening
of the event (or, if there is more than one such event, if the share of Series
1997-A Convertible Preferred Stock had been converted immediately before the
first of those events and the holder had retained all the Common Stock or other
securities or assets received after the conversion). An adjustment made pursuant
to this Section 5(e)(i) will become effective immediately after the Record Date
in the case of a dividend or distribution, and will become effective immediately
after the effective date in the case of a subdivision, split, reclassification
or combination. If such dividend or distribution is declared but is not paid or
made, the Conversion Price then in effect will be appropriately readjusted.
However, a readjustment of the Conversion Price will not affect any conversion
which takes place before the readjustment.

                        (ii) If the Corporation issues rights or warrants to 
the holders of its Common Stock as a class entitling them to subscribe for or
purchase Common Stock at a price per share less than the Conversion Price then
in effect at the Record Date for the determination of stockholders entitled to
receive the rights or warrants minus $0.125, the Conversion Price in effect
immediately before the issuance of the rights or warrants will be reduced in
accordance with the equation set forth on Exhibit A hereto, which is hereby
incorporated by reference herein. The adjustment provided for in this Section
5(e)(ii) will be made successively whenever any rights or warrants are issued,
and will become effective immediately after each Record Date. In determining
whether any rights or warrants entitle the holders of the Common Stock to
subscribe for or purchase shares of Common Stock at less than the Conversion
Price then in effect minus $0.125 and in determining the aggregate sale price of
the shares of Common Stock issuable on the exercise of rights or warrants and
any consideration to be received by the Corporation for the exercise of such
rights or warrants, there will be taken into account any consideration received
by the Corporation for the rights or warrants, with the value of that
consideration, if other than cash, to be determined by the Board of Directors of
the Corporation (whose determination, if made in good faith, will be
conclusive). If any rights or warrants which lead to an adjustment of the
Conversion Price expire or terminate without having been exercised, the
Conversion Price then in effect will be appropriately readjusted. However, a
readjustment of the Conversion Price will not affect any conversion which takes
place before the readjustment.

                       (iii) If the Corporation distributes to the holders of
its Common Stock as a class any shares of stock of the Corporation (other than
Common Stock) or evidences of indebtedness or assets (other than cash dividends
or distributions) or rights or warrants (other than those referred to in Section
5(e)(ii)) to subscribe for or purchase any of its securities, then, in each such
case, the Conversion Price will be reduced so that it will equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the Record Date for the distribution by a fraction of which the numerator is the
Current Market Price of the Common Stock on the Record Date for the distribution
less the then fair market value (as determined by the Board of Directors, whose
determination, if made in good faith, will be conclusive) of the stock,
evidences of indebtedness, assets, rights or warrants which are distributed with
respect to one share of Common Stock, and of which the denominator is the
Current Market Price of the Common Stock on that Record Date. Each adjustment
will become effective immediately after the Record Date for the determination of
the stockholders entitled to receive the distribution. If any distribution is
declared but not made, or if any rights or warrants expire or terminate without
having been exercised, effective immediately after the decision is made not to
make the distribution or the rights or warrants expire or terminate, the
Conversion Price then in effect will be appropriately readjusted. However, a
readjustment will not affect any conversion which takes place before the
readjustment.

                        (iv) If the Corporation issues or sells (or the 
Operating Partnership issues or sells) any equity or debt securities which are
convertible, directly or indirectly, into or exchangeable for shares of Common
Stock ("Convertible Securities") or any rights, options (other than the issuance
or exercise after the date hereof of stock options covering no more than
1,100,000 shares of Common Stock, subject to appropriate adjustment to the
extent that the Corporation (A) pays a dividend or makes a distribution on its
Common Stock in shares of its Common Stock, (B) subdivides its outstanding
Common Stock into a greater number of shares or (C) combines its outstanding
Common Stock into a smaller number of shares, issued to employees or directors
of the Corporation or its Subsidiaries under the Corporation's existing employee
stock incentive plans) or warrants (except the issuance after the date hereof of
shares of Common Stock pursuant to the warrants to purchase not more than

                                       11

<PAGE>

2,664,629 shares of Common Stock at a price per share of $11.79 outstanding on
the date hereof issued by the Corporation pursuant to that certain settlement
effective September 6, 1994) to purchase Common Stock at conversion, exchange or
exercise price per share which is less than the Conversion Price then in effect
minus $0.125, unless the provisions of Section 5(e)(ii) or (iii) are applicable,
the Corporation will be deemed to have issued or sold, on the date on which the
Convertible Securities, rights, options or warrants are issued, the maximum
number of shares of Common Stock into or for which the Convertible Securities
may then be converted or exchanged or which are then issuable upon the exercise
of the rights, options or warrants immediately prior to the close of business on
the date on which the Convertible Securities, rights, options or warrants are
issued, and the Conversion Price shall be adjusted downward as if it were an
event covered by Section 5(e)(v). However, no further adjustment of the
Conversion Price will be made as a result of the actual issuance of shares of
Common Stock upon conversion, exchange or exercise of the Convertible
Securities, rights, options or warrants. If any Convertible Securities, rights,
options or warrants to which this Section applies are redeemed, retired or
otherwise extinguished or expire without any shares of Common Stock having been
issued upon conversion, exchange or exercise thereof, effective immediately
after the Convertible Securities, rights, options or warrants expire, the
Conversion Price then in effect will be readjusted to what it would have been if
those Convertible Securities, rights, options or warrants had not been issued.
However, a readjustment will not affect any conversion which takes place before
the readjustment. For the purposes of this Section 5(e)(iv), (x) the price of
shares of Common Stock issued or sold upon conversion or exchange of Convertible
Securities or upon exercise of rights, options or warrants will be (A) the
consideration paid to the Corporation for the Convertible Securities, rights,
options or warrants, plus (B) the consideration paid to the Corporation upon
conversion, exchange or exercise of the Convertible Securities, rights, options
or warrants, with the value of the consideration, if other than cash, to be
determined by the Board of Directors of the Corporation (whose determination, if
made in good faith, will be conclusive) and (y) any change in the conversion or
exchange price of Convertible Securities or the exercise price of rights,
options or warrants will be treated as an extinguishment, when the change
becomes effective, of the Convertible Securities, rights, options or warrants
which had the old conversion, exchange or exercise price and an immediate
issuance of new Convertible Securities, rights, options or warrants with the new
conversion, exchange or exercise price.

                         (v) If the Corporation issues or sells any Common Stock
(other than (X) on conversion or exchange of Convertible Securities, (Y)
exercise of rights, options or warrants to which Section 5(e)(ii), (iii) or (iv)
applies, or (Z) not more than $150,000,000 in gross offering proceeds of Common
Stock in an underwritten, widely distributed offering at a price per share to
the public of not less than $11.3125 on or before November 30, 1997) for a
consideration per share less than the Conversion Price then in effect minus
$0.125, (or for a consideration per share of less than $11.3125 in the case of
an issuance referred to in clause (Z) of the parenthetical in this paragraph
(e)(v)) on the date of the issuance or sale (or on exercise of options or
warrants, for less than the Conversion Price then in effect minus $0.125 on the
date the options or warrants are issued), upon consummation of the issuance or
sale, the Conversion Price in effect immediately prior to the issuance or sale
will be reduced in accordance with the equation set forth on Exhibit A hereto,
which is hereby incorporated by reference herein.

                        (vi) If there is a reclassification or change of 
outstanding shares of Common Stock (other than a change in par value, or as a
result of a subdivision or combination or as a result of the Corporation's
open-market purchases of Common Stock pursuant to its Dividend Reinvestment
Plan), or a merger or consolidation of the Corporation with any other entity
that results in a reclassification, change, conversion, exchange or cancellation
of outstanding shares of Common Stock, or a sale or transfer of all or
substantially all of the assets of the Corporation, upon any subsequent
conversion of Series 1997-A Convertible Preferred Stock, each holder of the
Series 1997-A Convertible Preferred Stock will be entitled to receive the kind
and amount of securities, cash and other property which the holder would have
received if the holder had converted the shares of Series 1997-A Convertible
Preferred Stock into Common Stock immediately before the first of those events
and had retained all the securities, cash and other assets received as a result
of all those events. In the event that a transaction may be viewed as causing
this Section 5(e)(vi) to be applicable and 5(e)(iii) is also applicable, then
Section 5(e)(iii) will be applied and this Section 5(e)(vi) will not be applied.

                       (vii) From and after a Charter Breach (as defined below),
the Conversion Price from time to time in effect as provided elsewhere in this
Section 5(e) shall at all times be 50% of the amount elsewhere so determined
such that holders of shares of Series 1997-A Convertible Preferred Stock shall
receive, on conversion, two

                                       12

<PAGE>

times the number of shares of Common Stock to which they would be entitled in
the absence of the occurrence of a Charter Breach and the application of this
Section 5(e)(vii). A "Charter Breach" shall mean a failure by the Corporation to
observe and comply with Sections 3, 4 and 7 of this Certificate of Designation
or any successor provisions contained in any amendment to or restatement of the
Charter.

                      (viii) For the purpose of any computation under this 
Section 5(e), the "Current Market Price" of the Common Stock on any date will be
the average of the last reported sale prices per share of the Common Stock on
each of the twenty consecutive Trading Days (as defined below) preceding the
date of the computation. The last reported sale price of the Common Stock on
each day will be (A) the last reported sale price of the Common Stock on the
principal stock exchange on which the Common Stock is listed, or (B) if the
Common Stock is not listed on a stock exchange, the last reported sale price of
the Common Stock on the principal automated securities price quotation system on
which sale prices of the Common Stock are reported, or (C) if the Common Stock
is not listed on a stock exchange and sale prices of the Common Stock are not
reported on an automated quotation system, the mean of the high bid and low
asked price quotations for the Common Stock as reported by National Quotation
Bureau Incorporated if at least two securities dealers have inserted both bid
and asked quotations for the Common Stock on at least five of the ten preceding
Trading Days. If the Common Stock is not traded or quoted as described in any of
clause (A), (B) or (C), the Current Market Price of the Common Stock on a day
will be the fair market value of the Common Stock on that day as determined by a
member firm of The New York Stock Exchange, Inc., selected by the Board of
Directors. As used with regard to the Series 1997-A Convertible Preferred Stock,
the term "Trading Day" means (A) if the Common Stock is listed on at least one
stock exchange, a day on which there is trading on the principal stock exchange
on which the Common Stock is listed, (B) if the Common Stock is not listed on a
stock exchange, but sale prices of the Common Stock are reported on an automated
quotation system, a day on which trading is reported on the principal automated
quotation system on which sales of the Common Stock are reported, or (C) if the
Common Stock is not listed on a stock exchange and sale prices of the Common
Stock are not reported on an automated quotation system, a day on which
quotations are reported by National Quotation Bureau Incorporated.

                        (ix) No adjustment in the Conversion Price will be 
required unless the adjustment would require a change of at least 1% in the
Conversion Price; provided, however, that any adjustments which are not made
because of this Section 5(e)(ix) will be carried forward and taken into account
in any subsequent adjustment. All calculations under this Section 5 will be made
to the nearest cent or to the nearest one hundredth of a share, as the case may
be.

                         (x) If any one of the events in Sections 5(e)(i) 
through 5(e)(vii) occurs, then the Corporation will mail to the holders of
record of the Series 1997-A Convertible Preferred Stock, at least 15 days before
the applicable date specified below, a notice stating the applicable one of (i)
the date on which a record is to be taken for the purpose of the dividend,
distribution or grant of rights or warrants, or, if no record is to be taken,
the date as of which the holders of Common Stock of record who will be entitled
to the dividend, distribution or rights or warrants will be determined, (ii) the
date on which it is expected the Convertible Securities will be issued or the
date on which the change in the conversion, exchange or exercise price of the
Convertible Securities, rights, options or warrants will be effective, (iii) the
date on which the Corporation anticipates selling Common Stock for less than the
Conversion Price on the date of the sale (except that no notice need be given of
the anticipated date of sale of Common Stock upon exercise of options or
warrants which have been described in a notice to the holders of record of
Series 1997-A Convertible Preferred Stock given at least 15 days before the
options or warrants are exercised), or (iv) the date on which the
reclassification, consolidation, merger, share exchange, sale, transfer,
dissolution, liquidation or winding-up is expected to become effective, and the
date as of which it is expected that holders of record of Common Stock will be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon the reclassification, consolidation, merger, share
exchange, sale, transfer, dissolution, liquidation or winding-up. Failure to
give any such notice or any defect in the notice will not affect the legality or
validity of the reclassification, consolidation, merger, share exchange, sale,
transfer, dissolution, liquidation or winding-up. Whenever the Conversion Price
is adjusted, the Corporation will promptly send each holder of record of shares
of Series 1997-A Convertible Preferred Stock a notice of the adjustment of the
Conversion Price setting forth the adjusted Conversion Price and the date on
which the adjustment becomes effective and containing a brief description of the
events which caused the adjustment.

                                       13

<PAGE>

                        (xi) In the event (i) the last reported sale price per
share of Common Stock is less than $11.3125 on any day during the three full
Trading Day period (the "First Measurement Period) after the Corporation is
required or elects to restate, amend or alter or to issue a public announcement
restating, amending or altering any of its financial statements (or parts
thereof) and (ii) during the 30 full Trading Day period (the "Second Measurement
Period") after the end of the First Measurement Period, the last reported sale
price per share of Common Stock is not equal to or greater than $11.3125 for any
two full Trading Days within the Second Measurement Period, then the Initial
Conversion Price per share of Series 1997-A Convertible Preferred Stock will be
equal to the product of (i) the average of the last reported sale price per
share of Common Stock for each of the last 10 full Trading Days of the Second
Measurement Period and (ii) 107%, but in no event shall such Initial Conversion
Price exceed $12.125. If the Initial Conversion Price is to be adjusted as set
forth herein and, during the time from the initial issuance of Series 1997-A
Convertible Preferred Stock to the last day of the Second Measurement Period
there shall have occurred an adjustment to the Conversion Price as otherwise set
forth in this Section 5(e), such other adjustment or adjustments shall be
redetermined as if the Initial Conversion Price determined in accordance with
this Section 5(e)(xi) had been in effect on the date of the initial issuance of
Series 1997-A Convertible Preferred Stock.

                  (f) (i) The Corporation will at all times reserve and keep
available, free from preemptive rights, out of the authorized but unissued
shares of Common Stock, for the purpose of effecting conversion of the Series
1997-A Convertible Preferred Stock, the maximum number of shares of Common Stock
which the Corporation would be required to deliver upon the conversion of all
the outstanding shares of Series 1997-A Convertible Preferred Stock. For the
purposes of this Section 5(f)(i), the number of shares of Common Stock which the
Corporation would be required to deliver upon the conversion of all the
outstanding shares of Series 1997-A Convertible Preferred Stock will be computed
as if at the time of the computation all the outstanding shares of Series 1997-A
Convertible Preferred Stock were held by a single holder.

                      (ii) Before taking any action would cause an adjustment
reducing the Conversion Price below the then par value (if any) of the shares of
Common Stock deliverable upon conversion of the Series 1997-A Convertible
Preferred Stock, the Corporation will take all corporate action which may, in
the opinion of its counsel, be necessary in order that the Corporation may
validly and legally issue fully paid and non-assessable shares of Common Stock
at the adjusted Conversion Price.

                      (iii) The Corporation will seek to list the shares of 
Common Stock required to be delivered upon conversion of the Series 1997-A
Convertible Preferred Stock, prior to the delivery, upon each national
securities exchange, if any, upon which the outstanding shares of Common Stock
are listed at the time of delivery.

                  (g) The Corporation will pay any documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of shares of
Common Stock on conversion of Series 1997-A Convertible Preferred Stock;
provided, however, that the Corporation will not be required to pay any tax
which may be payable in respect of any transfer involved in the issue or
delivery of shares of Common Stock in a name other than that of the holder of
record of Series 1997-A Convertible Preferred Stock to be converted and no such
issue or delivery will be made unless and until the person requesting the issue
or delivery has paid to the Corporation the amount of any such tax or has
established, to the satisfaction of the Corporation, that the tax has been paid
or is not payable.

         Section 6. Status.

                  Shares of Series 1997-A Convertible Preferred Stock converted
pursuant to the terms hereof or otherwise acquired by the Corporation shall
automatically be retired upon such conversion or other acquisition, as the case
may be, shall not be reissued as shares of Series 1997-A Convertible Preferred
Stock and shall be restored to the status of authorized but unissued shares of
Preferred Stock, undesignated as to series.

         Section 7. Redemption after Notice of Mandatory Conversion.

                  (a) Notwithstanding anything to the contrary contained in
Section 5, each holder of Series 1997-A Convertible Preferred Stock will have
the right, exercised at any time after the Mandatory Conversion Notice

                                       14

<PAGE>

Date but prior to the Mandatory Conversion Date, to require the Corporation to
redeem any or all of the number of shares of Series 1997-A Convertible Preferred
Stock specified in the Notice of Mandatory Conversion that are owned of record
by the holder (the number of shares as to which each holder elects redemption
under this clause (a) being referred to as the "Identified Redemption Shares"),
at a redemption price per share (the "Redemption Price") equal to 110%
multiplied by the sum of (i) Stated Value plus (ii) the per share amount of the
sum of all Accrued Dividends with regard to the Series 1997-A Convertible
Preferred Stock (whether or not declared) through the Redemption Date, as herein
defined.

                  (b) In order to exercise a right to require the Corporation to
redeem a holder's Series 1997-A Convertible Preferred Stock, the holder must

                       DEVELOPMENT ACQUISITION AGREEMENT

         THIS DEVELOPMENT ACQUISITION AGREEMENT (this "Agreement") is made and
entered into this ________ day of ____________________, 1997, by and among
QUESTAR PROPERTIES, INC. (the "Developer"), Stephen M. Gorn, John B. Colvin and
BRI OP LIMITED PARTNERSHIP, a limited partnership ("BRI OP").

                                   BACKGROUND

         Developer is a Maryland corporation engaged in the business of land
development and the construction of multifamily apartment projects. Stephen M.
Gorn and John B. Colvin are principal shareholders of the Developer.

         BRI OP is a Delaware limited partnership engaged in the ownership and
operation of multifamily apartment projects. Berkshire Realty Company, Inc.
("Berkshire"), a publicly traded real estate investment trust, is a limited
partner in BRI OP.

         BRI OP desires to engage Developer to identify and acquire sites in the
Mid-Atlantic region of the United States for multifamily apartment projects and
to develop and construct multifamily apartment projects on the sites, and
Developer desires to accept such engagement.

               NOW, THEREFORE, in consideration of the foregoing, and other good
and valuable considerations, the receipt and sufficiency of which are hereby
acknowledged, the Developer and BRI OP covenant and agree as follows:

               1. Engagement of Developer. BRI OP hereby engages Developer and
Developer hereby accepts such engagement to be BRI OP's exclusive
developer/builder in connection with the identification, development and
acquisition of multifamily apartment development sites in the Mid-Atlantic
Region (i.e. Pennsylvania, Delaware, Maryland, Washington, D.C. and Virginia) of
the United States (each a "New Development Site") and the engineering, design
and construction of multifamily apartment projects of between 100 and 1,000
units (each a "New Development Project") on the New Development Sites.

               1.1. BRI OP agrees, subject to the terms of this Agreement, that
its engagement of Developer shall be exclusive for the Term (as hereinafter
defined) of this Agreement and that, accordingly, during the Term of this
Agreement:

               a. if BRI OP, Berkshire or any of its other affiliates is
presented by a third party with any site in the Mid-Atlantic Region for the
construction of a multifamily apartment project, BRI 

<PAGE>

OP will advise Developer of such opportunity and allow Developer to negotiate
for the acquisition of the site as a New Development Site in accordance with
this Agreement;

               b. except as provided in this Agreement, if BRI OP, Berkshire or
any of its other affiliates is or becomes the owner of any New Development Site
in the Mid-Atlantic Region for the construction of a Multifamily Apartment
Project, BRI OP will engage Developer to design and construct a Multifamily
Apartment Project on the New Development Site in accordance with this Agreement;
and

               c. except as provided in this Agreement, BRI OP will not engage
any other person or entity to acquire, develop or construct New Development
Sites or New Development Projects in the Mid-Atlantic Region nor will it, on its
own behalf, or through Berkshire or any of its other affiliates, acquire,
develop or construct New Development Sites or New Development Projects in the
Mid-Atlantic Region.

               1.2. Developer agrees that its engagement with BRI OP shall be
exclusive for the Term of this Agreement and that, accordingly, during the Term
of this Agreement:

               a. Developer, on its own behalf and on behalf of all of its
affiliates (as defined in Section 7.11) shall acquire New Development Sites and
construct New Development Projects only in the Mid-Atlantic Region and neither
Developer, on its own behalf or on behalf of any other person or entity or of
any of its affiliates, shall acquire any New Development Site in any location in
the United States (other than the Mid-Atlantic Region) nor develop or construct
any New Development Project in any location in the United States (other than the
Mid-Atlantic Region);

               b. except as provided in this Agreement, Developer and all of its
affiliates, shall acquire, develop and construct New Development Sites and New
Development Projects in the Mid-Atlantic Region solely for BRI OP, or its
affiliates and for no other person or party;

               c. except as provided in this Agreement, neither Developer, on
its own behalf, nor any of its affiliates shall agree with any other person or
entity, other than BRI OP or its affiliates to acquire, develop or construct any
New Development Site or New Development Project in the Mid-Atlantic Region nor
will Developer, on its own behalf, nor will any affiliate of Developer, acquire,
develop or construct New Development Sites or New Development Projects for its
own account in the Mid-Atlantic Region.

               d. Developer agrees that it will first present to BRI OP all
opportunities for New Development Sites of which Developer or any of its
affiliates (as defined in Section 7.11) becomes aware in accordance with the
provisions of Section 3 hereof prior to presenting such opportunities to any
other person or entity.


                                      -2-
<PAGE>


               1.3. Except as provided in this Agreement, Stephen M. Gorn and
John B. Colvin agree that during the Term of this Agreement, they will not,
directly or indirectly, as an individual, proprietor, partner stockholder,
officer, employee, director, joint venturer, investor, lender, consultant, or as
any other capacity whatsoever, acquire, develop or construct (or participate in
the formation of a business which does any of the same and/or assist any other
person in doing any of the same) any New Development Site or New Development
Project for any person or party, including themselves, other than BRI OP and its
affiliates except to the extent that the Developer is expressly permitted to do
so under the terms of this Agreement. The foregoing sentence shall not, however,
be construed to (a) prohibit Stephen M. Gorn and/or John B. Colvin from holding
an ownership interest in an entity, whether as a partner, stockholder, investor
or otherwise, in which he or they do not exercise or have the power to exercise
managerial control, do not own 50% or more of the economic interests in a
privately owned entity or 10% or more of the economic interests in a publicly
traded entity and for which they perform no services for which they are paid,
nor (b) apply to any of the properties that are the subject of the Related
Agreements or the subject of those certain Development Contribution Agreements
by and between affiliates of the Developer and BRI OP.

               1.4. The provisions of this Section 1 shall not apply to the
acquisition, development or construction of sites for the development of
for-sale housing, including, but not limited to single family, townhouse and
garden condominium projects and such sites shall not be deemed "New Development
Sites".

               2. Term.

               2.1. The term of this Agreement (the "Term") shall commence on
that date on which closing occurs under those certain agreements by and among
Developer and/or its affiliates and/or entities in which affiliates of Developer
are partners and BRI OP and/or its affiliates, as identified on Exhibit A hereto
(the "Related Agreements"), and shall expire on the fifth anniversary of such
date (the "Termination Date"). Notwithstanding the foregoing, if, after the Term
of this Agreement commences, both of the Termination Events (as hereinafter
defined) occur, then either party, by written notice to the other party, may
terminate this Agreement, in which event (a) the Termination Date shall be
deemed to have occurred upon receipt of such notice by the other party and the
Term of this Agreement shall expire on such Termination Date, (b) neither party
hereto shall have any further rights or obligations hereunder (except as
otherwise provided in Section 2.3), and (c) the Employment Agreements between
BRI OP and Stephen M. Gorn and John B. Colvin and the Consulting Agreement
between BRI OP and Morton Gorn shall terminate. The Termination Events shall
consist of (1) closing occurring under both of the Development Contribution
Agreements between BRI OP and Ironhorse Associates, L.L.C. ("Ironhorse") or if
closing does not occur under one or both of such Development Contribution
Agreements, such Development Contribution Agreement(s) as to which closing does
not occur having terminated for any reason (other than a default by the party
giving notice of termination), and (2) pursuant to Section 3.2, BRI OP having
determined on a

                                      -3-
<PAGE>

preliminary basis that the Threshold Conditions have not been satisfied with
respect to four consecutive New Development Sites presented by Developer.

               2.2. If closing under such Related Agreements has not occurred by
October 31, 1997, (such date being subject to further extension by mutual
written agreement of both parties) then this Agreement shall automatically
terminate and neither party hereto shall have any further rights or obligations
hereunder.

               2.3. Notwithstanding the occurrence of the Termination Date, (a)
this Agreement shall continue in effect as to any New Development Site acquired
by Developer or BRI OP prior to the Termination Date or placed under contract to
be acquired by Developer or BRI OP prior to the Termination Date, and (b)
termination upon the Termination Date however shall not affect the rights and
obligations of the parties hereto under any separate agreement including, but
not limited to, a Project Development Agreement (as hereinafter defined) or a
Tri Party Agreement (as hereinafter defined) hereafter entered into pursuant to
the provisions of this Agreement, which rights and obligations shall continue in
full force and effect.

               3. Acquisition of New Development Sites.

               3.1. BRI OP agrees to purchase on an annual basis from or through
Developer New Development Sites, to the extent available, which can accommodate
an aggregate minimum of 500 apartment units in New Development Projects which
satisfy the following conditions (the "Threshold Conditions"):

               a. Each New Development Site shall have potential for development
of a New Development Project of no less than 100 and no more than 1,000
apartment units.

               b. Each New Development Site shall be located in the Mid-Atlantic
Region.

               c. Each New Development Site shall have potential for development
of a 100% market rental New Development Project, with no rent controls or rent
subsidies.

               d. BRI OP shall have conducted and approved, in its reasonable
discretion, all due diligence inspections necessary to determine that an
adequate market for the New Development Project exists and that the proposed New
Development Project is appropriate for the market.

               e. BRI OP shall have no obligation to purchase and/or develop a
New Development Site unless the development costs (i.e. (i) hard development
costs, (ii) soft development costs, including interest and third party
professional costs, (iii) Land Acquisition Costs (as hereinafter defined), and
(iv) a G.C. Development Fee of 7% of the costs listed in (i) through (iii)
payable to Developer) reasonably projected by Developer and reasonably agreed to
by BRI OP (the "Projected Total Development Cost") to develop the New
Development Project are equal or less


                                      -4-
<PAGE>

than the Target Development Cost. The Target Development Cost is equal to
Stabilized NOI (as hereinafter defined) divided by the New Development Cap Rate
(as hereinafter defined).
               (i) Stabilized NOI is the net operating income at 93% occupancy
reasonably projected by Developer for the New Development Project and reasonably
agreed to by BRI OP for the 12-month period of operations of the New Development
Project commencing on the first month after 90% of the units in the New
Development Project have been leased for a period of 3 months.

               (ii) Operating expenses used in determining net operating income
shall consist of the following: the customary and reasonable operating expenses
of the Property, including, but not limited to, expenses for insurance, on-site
employees, utilities, lawn care, ordinary maintenance and repair, real estate
taxes, a management fee of 5%, advertising and leasing, interior painting and
redecorating, and general and administrative, but not including depreciation or
capital expenses.

               (iii) The New Development Cap Rate is the greater of (x) 10.0% or
(y) the sum of the BRI OP Blended Cost of Capital (as hereinafter defined) plus
100 basis points.

               (iv) The BRI OP Blended Cost of Capital is the sum of (x) the BRI
OP Equity Rate (as hereinafter defined) multiplied by 0.6, plus (y) the BRI OP
Debt Rate (as hereinafter defined) multiplied by 0.4.

               (v) The BRI OP Equity Rate is calculated as follows: (x) the BRI
OP Budgeted FFO (i.e. funds from operations as determined in accordance with the
NAREIT standards), as established by BRI OP (for the calendar year in which the
development and construction of the New Development Site is to commence) divided
by (y) the share price of the Common Stock of Berkshire at the time of analysis
divided by (z) the BRI OP Offering Cost Percentage (as hereinafter defined).

               (vi) The BRI OP Offering Cost Percentage is the quotient of the
total offering costs incurred by Berkshire in its 1997 public offering of Common
Stock divided by the total dollars raised by Berkshire in connection with the
public offering.

               (vii) The BRI OP Debt Rate is the permanent debt rate available
at the time of the analysis to qualified borrowers for a mortgage loan by the
Federal National Mortgage Association under its Tier IV loan guidelines.

               (viii) An example of the calculation of the BRI OP Blended Cost
of Capital is attached as Exhibit B.

               3.2. Developer shall make a formal, preliminary presentation to
BRI OP of the proposed New Development Site. BRI OP shall determine, on a
preliminary basis, whether all


                                      -5-
<PAGE>

Threshold Conditions have been satisfied within 15 days of formal preliminary
presentation by Developer. If BRI OP determines that the Threshold Conditions
are not satisfied, then notwithstanding the provisions of Section 1, Developer
shall be free to acquire the New Development Site and develop it free of all
exclusive and non-competition agreements contained in this Agreement and in any
of the Related Agreements or in any other documents executed in connection
therewith or pursuant thereto, including, but not limited to any Employment
Agreement or Consulting Agreement between BRI OP and any of Morton Gorn, Stephen
M. Gorn or John B. Colvin; provided, that if Developer so elects to acquire and
begins development of a multifamily apartment project on any such New
Development Site which BRI OP has not approved (a "Non-Approved New Development
Site"), for each Non-Approved New Development Site in number which Developer
acquires and begins development, notwithstanding the provisions of Section 1,
BRI OP shall be permitted to acquire and/or develop with other BRI OP personnel
or with any third party an equal number of multifamily apartment projects in the
Mid-Atlantic Region, free of all exclusive and non-competition agreements
contained in this Agreement and in any Related Agreement. If, based on the
preliminary presentation, BRI OP determines that the Threshold Conditions are
satisfied, then BRI OP shall proceed to acquire the New Development Site as
provided under Section 3.3. All determinations by BRI OP shall be made by
written notice to Developer, and the specific reasons for any determination
shall be set forth in the notice.

               3.3. Each New Development Site to be acquired by BRI OP shall
either be owned by Developer (or an affiliate of Developer that is either a
general partnership, limited partnership, or limited liability company) or, at
the option of Developer, under a binding purchase agreement between Developer
and a third-party seller. Closing on the acquisition of the New Development Site
shall occur either (a) within 60 days after BRI OP determines, on a preliminary
basis, that the Threshold Conditions have been satisfied if Developer or an
affiliate of Developer owns the New Development Site or (b) if the New
Development Site is under a binding purchase agreement, then on the date
required for closing under the binding purchase agreement. At Closing, as
applicable, either Developer shall convey the New Development Site to BRI OP, or
at the option of BRI OP, assign all of the partnership interests or limited
liability company interests in the entity owning the New Development Site to BRI
OP. If Developer owns the New Development Site, the land purchase price payable
by BRI OP shall be equal to the total price paid by Developer (including all
closing costs) at the time it acquired the New Development Site (i.e., a sale
"at cost"). If the New Development Site is under a binding purchase agreement,
the Developer shall assign the existing purchase agreement and the third-party
seller shall convey the New Development Site directly to BRI OP, in which event
the land purchase price shall be equal to the price set forth in the existing
purchase agreement (in either case, the "Land Purchase Price"). In addition,
regardless of the method by which BRI OP acquires the New Development Site, at
Closing, BRI shall pay to Developer an acquisition fee equal to 7% of the Land
Purchase Price (the "Land Acquisition Fee"). Regardless of the method by which
BRI OP acquires the New Development Site, all closing costs not borne by a
third-party seller, including, but not limited to, title insurance premiums,
survey costs and all transfer recordation, documentary 


                                      -6-
<PAGE>

stamp and other taxes imposed on the conveyance, shall be paid by BRI OP. The
Land Purchase Price, such closing costs and the Land Acquisition Fee are
referred to collectively as the "Land Acquisition Costs."

               4. Development and Construction.

               4.1. Within 30 days after closing by BRI OP on the New
Development Site, Developer and BRI OP shall agree upon a projected timetable
and schedule of responsibilities for obtaining the information and performing
such studies and analyses as are necessary to determine, on a final basis,
whether the Threshold Conditions are satisfied.

               4.2. Within 6 months after Closing by BRI OP on the New
Development Site, Developer shall make a formal, final presentation to BRI OP of
the New Development Project. BRI OP shall determine, on a final basis, whether
all Threshold Conditions for development of the New Development Project upon the
New Development Site are satisfied within 15 days of formal, final presentation
by Developer. At the time that BRI OP makes such decision, BRI OP shall elect
one of the following options to proceed after acquisition: (a) promptly begin
development of the New Development Site with Developer as provided in Section
4.3, or (b) if and only if, in BRI OP's reasonable judgment, the capital markets
do not currently make available sufficient capital for the New Development
Project, but the New Development Site represents an attractive site for future
development of a New Development Project when capital market conditions improve,
hold the New Development Site for future development in accordance with Section
5 below, or (c) if, based upon the final, formal presentation of Developer, BRI
OP has determined that the Threshold Conditions for development of the New
Development Site have not been met, hold and/or dispose of the New Development
Site in accordance with Section 5 below. Once a final determination is made to
proceed with development under Section 4.3, BRI OP shall be obligated to proceed
with the development and construction of the New Development Project unless, in
BRI OP's reasonable judgment, a material adverse change occurs in the capital
markets which makes the capital contemplated for the New Development Project
unavailable, in which case, BRI OP shall immediately notify Developer, and the
provisions of Section 5 below shall apply. All determinations by BRI OP shall be
made by written notice to Developer, and the specific reasons for any
determination shall be set forth in the notice.

                  4.3. If development of the New Development Site is to proceed,
then, within 30 days after the final determination that the Threshold Conditions
have been satisfied, BRI OP and Developer, or an affiliate of Developer
designated by Developer, shall enter into a development agreement for the
development of a New Development Project on the New Development Site acquired by
BRI OP (a "Project Development Agreement"). Under the terms of the Project
Development Agreement, the parties shall agree, among other terms:


                                      -7-
<PAGE>


               a. Developer shall be solely responsible to develop the New
Development Project, including without limitation, Developer shall (i) engage
the project architect and engineer to design the project, (ii) obtain all
governmental permits and approvals, (iii) engage and supervise all contractors
and suppliers (which may include affiliates of Developer), (iv) obtain the
construction loan financing, (v) clear, grade and develop the New Development
Site, and (vi) construct the New Development Project substantially in accordance
with the plans and specifications. Berkshire Property Management, at the sole
cost and expense of BRI OP shall be responsible for lease-up during and after
construction and property management of buildings following their completion and
as they are placed in service.

               b. With respect to construction financing, BRI OP shall not have
any liability or obligation for payment or performance under the construction
loan; it being agreed that the Developer shall be the borrower under the
construction loan and Stephen M. Gorn and John B. Colvin shall provide all
recourse guaranties and/or credit enhancement if required by the construction
lender; however, BRI OP shall agree to grant an accommodation first mortgage of
the New Development Site to the construction lender to secure the construction
loan. In consideration thereof, Stephen M. Gorn and John B. Colvin
("Guarantors") shall provide BRI OP with a recourse indemnity which shall
provide that if the construction lender forecloses the mortgage due to a failure
of the Developer to perform its obligations under the Project Development
Agreement, then the Guarantors shall pay to BRI OP a sum equal to the Land
Acquisition Cost paid by BRI OP for the New Development Site. Until the Payment
Date, Developer shall be responsible to pay for all costs of construction (hard
and soft costs) and to satisfy all requirements of the construction lender
(whether monetary or otherwise).

               c. On the Payment Date, the amount to be paid by BRI OP to
Developer for the New Development Project (the "Development Purchase Price")
shall be equal to the lesser of (i) the actual development costs (i.e. (x) hard
costs, (y) soft costs and (z) a G.C. Development Fee of 7% of the costs listed
in (a) and (b) above) or (ii) a guaranteed maximum price (as specified and
agreed to in the Project Development Agreement). All such sums shall be paid in
full on the Payment Date, without deduction, escrow or set off. On the Payment
Date, Developer shall be obligated to pay-off the construction loan in full and
to cause release of all deeds of trust, mortgages and other liens on the New
Development Project being held by the Lender.

               d. The payment of the Development Purchase Price by BRI OP to the
Developer on the New Development Project shall occur (such date of payment being
called the "Payment Date") upon the first business day of the first month after
the last to occur of (a) the substantial completion of construction of the New
Development Project, excluding punch-list items not affecting occupancy
(provided Developer shall thereafter complete all punch-list items at no expense
to BRI OP) (the "Completion Date") as evidenced by satisfaction of each of the
following conditions (the "Closing Conditions"): (i) final certificates of
occupancy issued by the appropriate governmental authority, and (ii) a
certificate of substantial completion issued by Developer or such affiliate of
Developer as Developer may designate to be the general contractor


                                      -8-

for construction of the Improvements ("Questar Builders") certifying that the
Improvements have been substantially completed in accordance with the plans and
specifications for the New Development Project, as such may be modified from
time to time by Developer, in accordance with the provisions of the Project
Development Agreement. The issuance of final lien waivers by Questar Builders
and subcontractors covering at least 95% of the construction cost shall be a
condition precedent to payment of the Development Purchase Price. If a dispute
shall exist as to whether substantial completion has occurred, the dispute shall
be promptly submitted to binding arbitration by a qualified third party mutually
acceptable to the parties or, if they are unable to agree upon a third party,
then by arbitrators appointed pursuant to the applicable rules of the American
Arbitration Association. The status of occupancy of the New Development Project
by rent-paying tenants and the rents generated by such occupancy by such
occupancy shall not be conditions to Closing.

               e. The Developer or any affiliate of Developer that enters into a
Project Development Agreement shall also have the right to collaterally assign
its interests under a Project Development Agreement to a construction lender
providing construction financing to the Developer for the New Development
Project (the "Lender"). If Developer so assigns the Project Development
Agreement, then BRI OP agrees to enter into an agreement with the Lender (the
"Tri Party Agreement") providing that: (a) BRI OP agrees to provide the Lender
with reasonable notice and opportunity to cure any default by Developer
thereunder; (b) BRI OP agrees not to modify or amend the Project Development
Agreement without the prior written consent of Lender, (c) BRI OP, at the
written request of Lender upon a default under the loan, will pay the
Development Purchase Price or such lesser amount as is required to satisfy the
loan directly to Lender provided that all conditions to payment of the
Development Purchase Price provided in the Project Development Agreement have
been satisfied; (d) BRI OP will permit Lender to perform any obligations of
Developer thereunder and will agree to recognize Lender as the Developer
thereunder should Lender succeed to the interest of Developer, provided,
however, that, in such event, Lender's liability under the Project Development
Agreement shall be limited to its interest in the New Development Site; and
further provided that (e) BRI OP will have no liability for payment of the
Lender's loan or the performance of any obligations under any of the loan
documents other than the Tri-Party Agreement.

               f. The parties shall negotiate in good faith to agree upon the
terms of the Project Development Agreement within the 30 day period after the
final determination that the Threshold Conditions have been satisfied as
provided in the introductory paragraph of this Section 4.3. If a dispute exists
as to the terms, the parties shall endeavor in good faith to resolve such
dispute within such 30 day period, but if the dispute cannot be resolved, then
such failure to agree shall be deemed a decision by BRI OP under Section 4.2(c)
that the Threshold Conditions have not been satisfied and the provisions of
Section 5 of this Agreement shall be applicable.


                                      -9-

               5. BRI OP Hold. If BRI OP opts not to promptly develop the New
Development Project as provided in paragraph 4.2(b) or to hold and/or dispose of
the New Development Site as provided in paragraph 4.2.c., then the following
provisions shall apply:

               5.1. BRI OP shall not be permitted to sell the New Development
Site to any third party (other than an affiliate) or to develop the New
Development Project with any third party developer or for its own account for a
period of 24 months after the closing by BRI OP on the acquisition of the New
Development Site (the "Exclusivity Period") without the prior consent of
Developer; provided, however, that if BRI OP elected to hold and/or dispose of
the New Development Site under paragraph 4.2.c. or if BRI OP is deemed to have
so elected under paragraph 4.3.f., then the Exclusivity Period shall be reduced
to 3 months. If the New Development Site is owned by or transferred or sold to
an affiliate of BRI OP, then the provisions of this Section 5 shall continue to
apply.

               5.2. At the end of the Exclusivity Period, if BRI OP has not
subsequently determined that the Threshold Conditions are satisfied and
proceeded to commence development with Developer under the provisions of Section
4.3, Developer shall have 120 days from the later of (i) the end of the
Exclusivity Period, or (ii) the date on which Developer receives written notice
from BRI OP of the expiration date of the Exclusivity Period, within which to
elect, by written notice to BRI OP, to purchase the New Development Site from
BRI OP for a purchase price equal to the Land Acquisition Costs. If Developer
purchases the New Development Site, it shall not be subject to any of the
exclusivity or non-competition agreements contained in this Agreement, the
Related Agreements or in any other documents executed in connection therewith or
pursuant thereto, including, but not limited to, any Employment Agreement or
Consulting Agreement between BRI OP and any of Morton Gorn, Stephen M. Gorn or
John B. Colvin. All closing costs, including, but not limited to, all transfer,
recordation, documentary stamp and other taxes imposed on the conveyance shall
be paid by Developer. Closing on the acquisition of the New Development Site by
Developer shall occur within 90 days after Developer's written election. At
Closing, BRI OP shall convey good and marketable title to the New Development
Site to Developer or an affiliate of Developer. Developer may elect, in lieu of
a conveyance of the New Development Site to Developer, to require BRI OP to
convey to Developer good and marketable title to 100% of the partnership or
membership interests in the entity owning the New Development Site.

               5.3. If Developer does not elect to purchase the New Development
Site, then, upon the expiration of the Developer's 120 day election period, (i)
BRI OP shall pay Developer an additional land acquisition fee (the "Second Land
Acquisition Fee") in the amount of 7% of the Land Price, (ii) Developer shall
have no further rights to acquire the New Development Site, and (iii) BRI OP
shall be free to either (a) continue to hold the New Development Site, (b) sell
the New Development Site to any third party or (c) decide in the future to
develop the New Development Site with Developer. If within three years
thereafter, Developer enters into a Project Development Agreement to develop the
New Development Site for BRI OP, then 

                                      -10-
<PAGE>

Developer shall give a credit to BRI OP against the Development Purchase Price
of the New Development Project equal to one-half of the Second Land Acquisition
Fee.

               Section 6. Default. If either party defaults in performing any of
its obligations hereunder, then the other party shall be entitled to exercise
any or all remedies as may be available at law or in equity on account thereof,
including, but not limited to, an action for specific performance, an action for
injunctive relief or an action for money damages. In any litigation between the
parties, the prevailing party shall be entitled to reimbursement by the
non-prevailing party for all court costs and reasonable attorneys' fees. The
restrictions contained in Section 1.2 and 1.3 of this Agreement are necessary
for the protection of the business and goodwill of BRI OP and its affiliates and
are considered by the Developer and Messrs. Gorn and Colvin to be reasonable for
such purpose. The Developer and Messrs. Gorn and Colvin agree that any breach of
Section 1.2 or 1.3 of this Agreement is likely to cause BRI OP and its
affiliates substantial and irrevocable damage and therefore, in the event of any
such breach, the Developer and Messrs. Gorn and Colvin agree that BRI OP, in
addition to such other remedies which may be available, shall be entitled to
specific performance and other injunctive relief.

               Section 7.  Miscellaneous.

               7.1. Assignment. Except as hereinafter provided, this Agreement
may not be assigned by either party hereto. BRI OP shall have the right to
designate an affiliate to accept title to a New Development Site, but shall
remain fully liable for the performance of all of its obligations hereunder
notwithstanding such designation. Developer may designate an affiliate of
Developer to acquire title to a New Development Site and/or to enter into a
Project Development Agreement, such designated affiliate alone being responsible
for the performance of all of the obligations hereunder with respect to the New
Development Site or for the performance of the obligations under the Project
Development Agreement.

               7.2. Integration. This Agreement embodies and constitutes the
entire understanding between the parties with respect to the transactions
contemplated herein, and all prior agreements, understandings, representations
and statements, oral or written, including, but not limited to, the agreements
contained in the letter of intent dated May 5, 1997, as amended to date, are
merged into this Agreement. Neither this Agreement nor any provision 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 termination is sought, and then only to the extent set
forth in such instrument.

               7.3. Governing Law. This Agreement shall be governed by, and
construed in accordance with the laws of the State of Maryland. Developer and
BRI OP consent to the personal jurisdiction of the federal and state courts of
the State of Maryland and agree that service of process may be made upon each of
them by certified mail, return receipt requested or in any other manner
permitted by law.

               7.8. Headings; Schedules; Exhibits. The headings of the various
Sections of this Agreement have been inserted solely for purposes of
convenience, are not part of this Agreement and shall not be deemed in any
manner to modify, explain, expand or restrict any of the provisions of this
Agreement. All references to Sections or paragraphs herein shall be to the

               7.9. Publicity. In no event shall either the Developer or the BRI
OP issue any press release or otherwise communicate to any third party any
information regarding this Agreement or the transactions contemplated hereby
unless the other party has consented thereto and to the form and substance of
any such statement, announcement or release; provided, however, that nothing
herein shall be deemed to limit or impair in any way any party's ability to
disclose the details of the transactions contemplated hereby to the accountants,
attorneys or other authorized agents of such party or as such party deems
necessary or desirable pursuant to any court or governmental order or applicable
securities regulations or financial reporting requirements, nor shall BRI OP or

such party. The provisions of this Section 7.9 shall survive any closing on a
New Development Site or New Development Project.

               7.10. Force Majeure. Each party is excused from performing any
act required under this Agreement (except for payment of money) while delayed or
prevented by a cause not within its reasonable control, such as a strike,
lockout, or other labor dispute, insurrection, riot, mob violence, or other
civil commotion, sabotage, inability to obtain labor, material, equipment or
utility services in the open market, failure of transportation, water, sewer or
other utility or building permit moratorium, road construction moratorium, or
other governmental action (including enforcement of requirements of any adequate
public facilities ordinance) condemnation, adverse weather, fire or other
casualty event, or other act of God (each of which is called a "Force Majeure
Event"). Time periods and dates in this Agreement are extended to account for
the delay or prevention caused by the Force Majeure Event.

               7.11. Affiliates. For purposes hereof, an "affiliate" of a party
shall be deemed to include any person or entity controlling, controlled by, or
under common control with such party. Berkshire shall be deemed an affiliate of
BRI OP, and Morton Gorn, Stephen M. Gorn and John B. Colvin and any entities
controlled by them shall be deemed affiliates of Developer.

               7.12. Interpretation. If any restriction set forth in Sections
1.1, 1.2 or 1.3 is found by any court of competent jurisdiction to be
unenforceable because it extends for too long a period of time or over too great
a range of activities or in too broad a geographic area, it shall be interpreted
to extend only over the maximum period of time, range of activities or
geographic area as to which it may be enforceable.

               IN WITNESS WHEREOF, the parties hereto have executed this
Agreement under their respective hands and seals as of the day and year first
above written.

                  - Example of BRI OP Blended Cost of Capital -

Blended Cost of Capital = (BRI OP Equity Rate x .6) + (BRI OP Debt Rate x .4)

BRI OP Equity Rate = BRI OP Budgeted FFO/ Share Price/ OP Offering Cost
Percentage

BRI OP Debt Rate = Permanent Debt Rate FNMA Tier IV Loan

If the following assumptions are used, then the calculation is as follows:

Budgeted FFO = $1.14 
Share Price = $11.25 
FNMA Tier IV = 7.5%
Offering Cost Percentage = 1-.07 = .93%
BRI OP Equity Rate = (1.14/11.25) / .93 = 10.896%
BRI OP Debt Rate = 7.5%
Blended Cost of Capital = (10.896% x .6) 6.537% + (7.5% x .4) 3.00%  = 9.537%

                                    SECTION 1
                                    ---------

             CONTRIBUTION OF MEMBERSHIP INTERESTS AND DUE DILIGENCE
             ------------------------------------------------------

         1.01 The Transferor Members shall contribute to the BRI Partnership,
and the BRI Partnership shall accept from the Transferor Members, in exchange
for either cash or BRI Partnership Units, and upon the terms and conditions set
forth in this Agreement, all of the Transferor Members' membership interests in
the Transferor Company (the "Transferor Membership Interests"). The percentage

is listed on Exhibit I. At the Closing (as defined in Section 3.01), the
Transferor Members shall, respectively, contribute, assign, transfer and deliver
the Transferor Membership Interests to the BRI Partnership, or its designees as

Interest in the form of Exhibit III attached hereto (the "Transferor
Assignment"). Immediately thereafter, the Transferor Members and the BRI
Partnership, or its designees, shall execute and deliver an Amended and Restated
Operating Agreement in the form of Exhibit IV attached hereto (the "Amended
Transferor Operating Agreement") and an Amended and Restated Articles of
Organization in the form of Exhibit V attached hereto (the "Amended Transferor
Company Articles") pursuant to which the BRI Partnership, or its designees,

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").

         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 Company on or before October 1, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Company 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". Any easements or other agreements reasonably required
for the development and construction of the Property and the Improvements now or
hereafter entered into by the Transferor Company; including an agreement for the
shared use and the sharing of the operating expenses of the common recreational
facilities located on the Property and an easement declaration creating
cross-easements for the roads, storm water management ponds and the sewage
pumping station on the Property, in form and content reasonably satisfactory to

Specifications and, in the reasonable


                                      -3-
<PAGE>

discretion of the BRI Partnership, do not materially interfere with the intended
use of the Property nor materially affect the value of the Property, shall also
constitute Permitted Exceptions.

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at the BRI Partnership's sole cost, shall obtain a new
commitment (the "Updated Commitment") for Title Insurance for an ALTA Form B
Owner's Title Insurance Policy from Lawyer's Title Insurance Corporation (the
"Title Insurer"). The Updated Commitment shall insure fee simple title to the
Property in the sole name of the Transferor Company and shall be in the amount
of $25,862,791. The Updated 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 and are available under the law of the state in
which the Property is located. If any new exceptions to title appear in the
Updated Commitment that do not constitute Permitted Exceptions and that are
unacceptable to the BRI Partnership, in its reasonable discretion, the BRI
Partnership may notify the Transferor Company within thirty (30) days after the
Completion Date Notice.

         If any exceptions in the Commitment or the Updated Commitment are
unacceptable to the BRI Partnership in accordance with the foregoing provisions,
and the BRI Partnership timely notifies the Transferor Company in writing of
such fact as above provided, the Transferor Company shall have thirty (30) days
from the date the Transferor Company receives notice of such unacceptable
exceptions, at the option of the Transferor Company, to remove or cure such
exceptions, provided further, the Transferor Company 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 liens for real estate taxes and current water and sewer charges for the
fiscal year in which Closing occurs, 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 Company at Closing. The
Transferor Company shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Company, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Company will attempt to cure such unacceptable exceptions.
If the Transferor Company 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 Company 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 Company or
(ii) waive such exceptions and accept title subject thereto, in which event
there shall be a reduction in the Purchase Price (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 22, 1997, the Transferor Company
shall provide to the BRI Partnership a copy of its existing survey (the
"Survey") of the Land and any Improvements.

         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 Company on or before
October 1, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Company 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."

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at its sole cost and expense, shall obtain an updated
survey (the "Updated Survey") by a registered land surveyor (the "Surveyor")
acceptable to the BRI Partnership, which Updated 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
Updated Survey and the recorded legal description. The BRI Partnership shall
provide a copy of the Updated Survey to the Transferor Company promptly after
its receipt thereof. If any new matters appear on the Updated Survey that do not
constitute Permitted Exceptions, do not simply reflect the construction of the
Improvements in locations that do not encroach upon property lines, setback
lines or easements, and are unacceptable to the BRI Partnership in its
reasonable discretion, the BRI Partnership may notify the Transferor Company
within forty (40) days after the Substantial Completion Date Notice.

         If any survey matters are unacceptable to the BRI Partnership in
accordance with the foregoing provisions, and the BRI Partnership timely
notifies the Transferor Company in writing of such fact as above provided, the
Transferor Company shall have thirty (30) days from the date the Transferor
Company receives notice of such unacceptable survey matters, at the option of
the Transferor Company, to cure such unacceptable survey matters. The Transferor
Company shall be deemed to have refused to cure any unacceptable survey matters
unless the Transferor Company, within ten (10) days after receipt of notice from
the BRI Partnership, shall notify the BRI Partnership in writing that the
Transferor Company will attempt to cure such unacceptable survey matters. If the
Transferor Company 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


                                      -5-
<PAGE>

after the Transferor Company 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 Company 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     Construction and Inspection.

                  (a) Plans and Specifications. Prior to the date of this
Agreement, Transferor Company has delivered to BRI Partnership true, correct and
complete copies of the Plans and Specifications for the construction of the
Improvements as set forth on Schedule C attached hereto.

                  (b) Transferor Company to Construct Improvements. Transferor
Company shall, at Transferor Company's expense, obtain all permits and construct
the Improvements on the Land in accordance with the Plans and Specifications, as
the same may be modified by change order in accordance with this Agreement. All
work shall be done in a good and workmanlike manner using new, good quality
materials, free of all defects and in compliance with all Codes (as defined in
Section 5.21), permits, approvals, title restrictions and insurance
requirements. Transferor Company shall obtain builder's risk insurance on the
Improvements in the amount of the construction cost of those buildings from time
to time for which construction has commenced. Transferor Company shall deliver a
certificate of such insurance to BRI Partnership. Transferor Company shall
maintain such insurance in force and effect through the course of construction
and until Closing hereunder.

                  (c) Inspection of Construction; Correction of Defects. BRI
Partnership and its engineers, consultants and agents may inspect the
construction of the Improvements from time to time during the course of
construction upon reasonable notice to the Transferor Company. After receipt
from the Transferor Company of written notice that the requirements of Section
3.02(a)(i) and (ii) have been satisfied (the "Inspection Notice"), BRI
Partnership and its engineers, consultants and agents shall inspect the
construction of the Improvements upon reasonable notice to Transferor Company to
determine whether such construction is completed in accordance with the Plans
and Specifications. Within 30 days after the Inspection Notice, BRI Partnership
will give written notice to Transferor Company of any nonconformities with the
Plans and Specifications and defects or deficiencies in construction identified
by BRI Partnership. Unless Transferor Company disagrees with BRI Partnership,
which disagreement shall be expressed by giving written notice to the BRI
Partnership stating the basis for said disagreements, within 10 days after such
BRI Partnership notice, Transferor Company, at Transferor Company's expense,
shall commence to correct, repair or replace any such nonconformities, defects
or deficiencies and shall diligently continue thereafter until completion of
such corrections, repairs or replacements, and, if such deficiencies are of such
a magnitude that Closing would not otherwise be required to occur under Section
3.02 and Section 5.30, the Closing Date shall be extended until the deficiencies
are corrected. Any dispute shall be resolved by arbitration in accordance with
Section 3.02.

<PAGE>

                  (d) Change Orders. The Transferor Company shall not change or
modify the Plans and Specifications without prior written approval of the BRI
Partnership, such approval not to be unreasonably withheld, provided, however
that the following changes shall not require BRI Partnership's approval: (i)
changes required by the construction lender or governmental authorities, and
(ii) changes in the design of the Improvements resulting in a decrease or
increase in construction cost by less than $100,000 for an individual change and
less than $250,000 in the aggregate. The Transferor Company shall give written
notice to BRI Partnership of all proposed changes to the Plans and
Specifications by sending a complete copy of the change, together with copies of
any plans or drawings related thereto. BRI Partnership shall give its written
approval or disapproval within five (5) business days thereafter. If BRI
Partnership disapproves any such change, the Transferor Company shall not
implement same.

                  (e) Completion. The Transferor Company shall diligently
attempt to complete construction of the Improvements in accordance with the
Plans and Specifications, as modified in accordance with this Agreement, and in
compliance with all Codes (as defined in Section 5.21 hereof) by December 31,
2003 (the "Scheduled Completion Date"). For purposes of this Agreement, the
"Completion Date" shall be the date upon which all of the Closing Conditions
shall have been satisfied as set forth in Section 3.02.

                  (f) Force Majeure. In the event that the Transferor Company is
delayed in the commencement or completion of construction of the Improvements by
acts of God, war, civil commotion, fire, flood or other casualty, labor
difficulties, strikes, shortages of labor, materials or equipment, undue delay
in action by governmental authorities, governmental or utility company refusal
to issue building, construction, utility, occupancy or other permits or
approvals, water, sewer or other utility moratorium (including enforcement of
the requirements of any adequate public facilities ordinance) or other causes
beyond the Transferor Company's reasonable control (a "Force Majeure Event"),
the Scheduled Completion Date shall be extended for the period of delay, not to
exceed 12 months. If a Force Majeure Event continues in effect for a period in
excess of 12 months, during which construction is delayed, then the Transferor
Company may, by notice to BRI Partnership terminate this Agreement, in which
event the Deposit shall be returned to the BRI Partnership and neither party
shall have any further liability to the other hereunder. In addition,
simultaneously with closing under the Related Agreements, the Transferor Company
shall execute and deliver to BRI Partnership the Right of First Offer Agreement
attached hereto as Exhibit IX, which Right of First Offer Agreement shall
contain, among other provisions a Right of First Refusal which provides: (a)
that the BRI Partnership shall have a right of first refusal to purchase the
Property following the termination of this Agreement pursuant to this Section
1.04(f), (b) BRI Partnership shall have a period of 15 business days, following
receipt of a bona fide third party letter of intent to purchase the Property, to
agree to purchase the Property on the same terms and conditions as set forth in
the letter of intent, and (c) such Right of First Offer Agreement shall be
subordinate to any mortgage or deed of trust securing construction financing on
the Property.

         1.05     Environmental Due Diligence Inspection.

                  (a) On or before September 22, 1997, the Transferor Company
shall deliver to the BRI Partnership a copy of its environmental report for the
Property (the "Initial Environmental Report"). Should the BRI Partnership
decide, in its sole judgment, during the period up to and including October 1,
1997 (the "Due Diligence Period") that the Initial Environmental Report is
unsatisfactory, the BRI Partnership shall have the right to terminate this
Agreement by giving written notice of its election to do so 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. 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 the period expiring
30 days after the Substantial Completion Date Notice during regular business
hours and on reasonable prior notice to the Transferor Company, inspect the
Property to determine the presence of any Hazardous Materials (as defined in
Section 5.20) and the compliance of the Property with Environmental Laws (as
defined in Section 5.20) 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 Company 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 Company in this Agreement. Should the BRI Partnership decide, in its
reasonable judgment, that there exists an environmental risk with respect to the
Property (excluding such items as asbestos roof shingles, asbestos floor tile
and mastic, PCBs in electric light ballasts, HCFCs or CFSs in HVAC units, the
presence of usual and customary cleaning and maintenance supplies and similar
items that are typically handled through the adoption of appropriate operations
policies), during the period expiring 30 days after the Substantial Completion
Date Notice 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 Company on or before 30 days
after the Substantial Completion Date, and upon the giving of such notice this
Agreement shall be of no further force or effect. Notwithstanding the foregoing,
the BRI Partnership may not disapprove or object to any matter disclosed by the
Environmental Inspection that was disclosed in the Initial Environmental Report.
If the BRI Partnership shall fail to exercise such termination right within any
such 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 1.05.
The BRI Partnership shall pay when due all fees and expenses incurred in the
performance of the Environmental Inspection performed at its request.

                  (b) From and after the date of this Agreement, the Transferor
Company shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to 


                                      -8-
<PAGE>


examine (including, without limitation, the right to audit) the Transferor
Company'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 Company's financial records relating to the Property have been
audited, the Transferor Company agrees to deliver any reports relating to such
audits to the BRI Partnership. The Transferor Company shall provide the BRI
Partnership with such information as the Transferor Company 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 Company, all taxes and utility payments made 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 1.05(b) 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 Company if the Closing does not occur.

                  (c) The BRI Partnership shall indemnify the Transferor Members
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
Members 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 Members 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 1.05(c) shall survive the Closing
or any termination of this Agreement; provided, however, that no claim by the
Transferor Members under this Section 1.05(c) 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 Members 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 Members hereunder.

         1.06 Tax Treatment. The parties intend that, to the extent the
Transferor Members receive BRI Partnership Units as the consideration for the
contribution of the Transferor Membership Interests by the Transferor Members to
the BRI Partnership in accordance with Section 1.01 of this Agreement, such
contribution shall 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 


                                      -9-
<PAGE>

provisions). The BRI Partnership and the Transferor Members agree to report such
transaction for federal and applicable state income tax purposes consistently
with the intent set forth in this Section 1.06.


                                    SECTION 2
                                    ---------

                                  CONSIDERATION
                                  -------------

         The consideration for the Membership Interests (the "Consideration
Amount"), subject to the adjustments contained in Section 12 of this Agreement,
shall be determined pursuant to the provisions of Section 2.04, and shall be
paid by the the BRI Partnership to the Transferor Members in the following
manner:

         2.01     Deposit.

                  (a) Simultaneously with the execution of this Agreement, the
the BRI Partnership shall deliver to Lawyers Title Insurance Corporation (the
"Escrow Agent") the sum of ONE DOLLAR ($1.00) (the "Initial Deposit") by check
(subject to collection) as a Deposit to be held in an interest-bearing escrow
account on account of the Consideration Amount. Said sum, together with any
interest earned thereon, is hereinafter called the "Deposit."

                  (b) At the Closing, the Deposit shall be returned by the
Escrow Agent to BRI Partnership.

         2.02 Balance. At the Closing, the BRI Partnership shall deliver to the
Transferor Members the Base Consideration, plus, if then due, any Additional
Consideration Installments, subject to the adjustments described in Section 12
of this Agreement by federal wired funds. Prior to any delivery to the
Transferor Members of the Base Consideration, there shall be deducted from the
Base Consideration an amount equal to the sum required to pay off the
Construction Loan in full and to remove all other Monetary Liens and
simultaneously with the Closing, the BRI Partnership shall pay off the
Construction Loan. At the Transferor members' option, to be exercised
irrevocably by written notice to the BRI Partnership given at least 15 days
prior to the satisfaction of the Closing Conditions, all or a portion of the
Consideration Amount shall be delivered to the Transferor Members in the form of
BRI Partnership Units in the BRI Partnership. If the Transferor Members exercise
such option, then the number of BRI Partnership Units, the rights and
limitations upon such units and the method by which the units are delivered to
the Transferor Members at Closing shall be as provided in Sections 2.02 (a), (b)
and (c) below. If the Transferor Members do not exercise the foregoing option in
a timely manner, all consideration payable under this Agreement shall be paid in
cash by federal wired funds and the following Sections of this Agreement shall
be, without further action by any party, null and void and without any further
force or effect upon the parties: 1.06, 2.02(a) through (c), 5.34, 6.03, 6.05,
6.06, 6.08, 6.09, 6.10, 6.12 through 6.16, 10.01(e), 10.04, 11.01(a) (ii), (iii)
and (iv) and 11.01(d) (last sentence only), 11.03 and 12.04.

<PAGE>

                  (a) The number of BRI Partnership Units to be issued to the
Transferor Members at Closing shall be that number determined by dividing the
portion of the Consideration Amount to be paid in BRI Partnership Units to each
Transferor Member by the value of one BRI Partnership Unit. The parties agree
that, for purposes of this Agreement, the value of each BRI Partnership Unit
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 ten (10) business days prior to the day which
is five (5) business days before the Closing. If the calculation provided for
above results in a fraction of a BRI Partnership Unit to be delivered to a
Transferor Member, the number of BRI Partnership Units to be delivered shall be
rounded up or down to the nearest whole number of BRI Partnership Units.

         Attached hereto as Exhibit I is a schedule (the "Transferor Allocation
Schedule") prepared by the Transferor Members setting forth (i) the name of each
Transferor Member, and (ii) the percentage interest of each Transferor Member,
together with an investor questionnaire in the form attached hereto as Exhibit 5
(the "BRI Questionnaire") for each Transferor Member. In the event that any
Transferor Member 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 Members all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Members
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Members 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 Members in accordance with the election made by the Transferor
Members pursuant to Section 2.02. The BRI Partnership shall have no obligation
or liability with respect to the preparation or accuracy of the Transferor
Allocation Schedule.

                  (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 any Transferor Member 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 Member 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 Members and Berkshire 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 Members a certified copy of the
Registration Rights Agreement.

                  (c) The Transferor Members, 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, 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 this Section, 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 Members in the event of a
decrease or increase in the market value of the common stock of BRI.

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

         2.04 Calculation of Consideration Amount. The Consideration Amount for
the Transferor Membership Interests shall consist of a base consideration amount
("Base Consideration") plus additional consideration installments ("Additional
Consideration Installments").

                  (a) The Base Consideration for the Transferor Membership
Interests shall be Twenty-Five Million, Eight Hundred Sixty-Two Thousand, Seven
Hundred Ninety-One Dollars ($25,862,791).

                  (b) In addition to the Base Consideration, the BRI Partnership
shall pay one or more additional consideration installments (the "Additional
Consideration Installments"), if any, on a quarterly basis with the first
payment, if then due, on the date of Closing and on the first day of each
quarter (defined as a period of three full calendar months, plus, for the first
quarter, any partial calendar month after the date of Closing) thereafter for a
total of 18 full calendar months after the Closing (the "Earn Out Period"). As
of the Closing and as of the first day of each quarter thereafter, Stabilized
NOI shall be determined as provided below, and each Additional Consideration
Installment, if any, will be equal to the Stabilized NOI divided by 10% (the
"Cap Rate") and then reduced by the Base Consideration and any prior Additional
Consideration Installments.

                  (c) Stabilized NOI shall be calculated for purposes of
determining the Additional Consideration Installments as follows: 12 times the
monthly actual income for the Property, (provided that if occupancy rates exceed
95%, then actual income shall be calculated as if the Property had an occupancy
rate of 95%) for the month preceding the payment date less Seven Hundred
Eighty-Eight Thousand, Four Hundred Forty Dollars ($788,440) (representing the
agreed-upon annual Projected Operating Expenses for the Property), provided
that, on the first anniversary of the date of Closing under this Agreement, the
Projected Operating Expenses shall be adjusted by the percentage change in the
CPI-U, U.S. Cities Average for the period from the date of Closing under this
Agreement until the anniversary date.

         3.01 Except as otherwise provided in this Agreement, the delivery of
all documents necessary for the closing of the transactions contemplated by this

time to time by the Transferor Company in accordance with this Agreement, or (b)
the Stabilization Date. If a dispute shall exist as to whether substantial
completion has occurred, the dispute shall be promptly submitted to binding
arbitration by a qualified third party mutually acceptable to the parties or, if
they are unable to agree upon a third party, then by arbitrators appointed
pursuant to the applicable rules of the American Arbitration Association.

         3.03     The Stabilization Date for the Property shall be as follows:

The first day of that month which first occurs after 90% of the apartment units

condemnation, a widening change of grade or limitation on use of streets, a
special assessment or a change in zoning classification, that would adversely
affect the continued use and operation of the Property as currently used and

against or by the Transferor Company, anticipated or contemplated by the
Transferor Company.

         5.26 Liens. The Transferor Company agrees to keep the Property free
from mechanics and materialmen's liens or other liens or encumbrances occasioned
by the actions of the Transferor Company or its contractors or subcontractors

encumbrances and all attorneys' fees and other costs and expenses incurred by
reason thereof.

         5.27 Essential Facilities. Except as set forth in Schedule 5.27, the
Property is an independent unit which does not now rely on any facilities (other

or public or private utility and water companies) located on any property not
included in the Property to fulfill any municipal or governmental requirement or
for the furnishing to the Property of any essential building systems or
utilities. Except as set forth on Schedule 5.27, no property not included in the
Property relies for its operation, maintenance or legal compliance on any
facilities located on the Property.

         5.28 Legal Access. There is, or prior to Closing will be, direct legal
access from a public way to the Property. Upon completion of construction of the
Improvements, all necessary curb cuts, access permits and other governmental
approvals required to provide such access shall have been issued and shall be in
full force and effect.

         5.29 Public Improvements. To the best knowledge of the Transferor
Company and except as shown on the Plans and Specifications, there are no
written or proposed plans to widen, modify, or realign any street or highway or
any existing or proposed eminent domain proceedings which would affect the
Property in any way that would have a Material Adverse Effect. To the best
knowledge of the Transferor Company, there are no presently planned public
improvements which would result in the creation of a special improvement or
similar lien upon the Property.

         5.30 Condition of Improvements. The Property, including, without
limitation, curbs, sidewalks, air conditioning, roofs, mechanical, electrical,
HVAC systems and equipment, plumbing, drainage and heating systems and other
mechanical systems, shall at the time of Closing be in good order and operating

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

                  (a) Such Transferor Member 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

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 Member.

                  (c) Such Transferor Member acknowledges and agrees that, for
the reasons set forth in Sections 5.34(a) and (b) above, the BRI Partnership

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

Agreement and has not relied upon the BRI Partnership, its affiliates or its
other legal counsel and advisors for any explanation of the application of the

                  (f) Such Transferor Member acknowledges and agrees that:

                           (i) the BRI Partnership Units to be acquired by it

president of The Questar Management Company, shall remain employed by the
Management Company until the expiration of the Earn Out Period, his principal
place of employment shall remain at the principal regional office of the

the Transferor Members at their option, may elect (a) to terminate the
management agreement with BRI Partnership and either manage, lease and operate
the Property on their own behalf or retain such other persons or entities to do
so as they deem appropriate on substantially the same terms (including, but not
limited to, the same management fee) as are provided in the management agreement
with BRI Partnership, and (b) to attempt to recruit Patrick Connelly as their
full-time employee.

                  (b) any willful action by the Transferor Company which would
render any of representations and warranties contained in Section 5 hereof
untrue in any respect at and as of the Closing Date with the same effect as
though such representations and warranties had been made at and as of the
Closing Date;

and, except with the prior written consent of the BRI Partnership, the

taxable year ending December 31, 1991, BRI has been organized in conformity with
the requirements for qualifications 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
Internal Revenue Code of 1986, as amended.

                  (e) Certificate as to Representations and Warranties. Deliver

Members a true and correct copy of the BRI Partnership Agreement, as amended and
in effect on the Closing Date, certified as such by an officer of the general
partner of the BRI Partnership.

                  (h) Other Documents. Such other documents, instruments or
agreements which the BRI Partnership is required to deliver to the Transferor
Members pursuant to any other provisions of this Agreement or which the
Transferor Members may, either at or subsequent to the Closing, deem reasonably
necessary in order to consummate the transactions contemplated by this Agreement
or to better vest in the Transferor Members title to the BRI Partnership Units.
The provisions of this Section 11.01(h) shall survive the Closing indefinitely.

         11.02 BRI Partnership's Expenses. The BRI Partnership shall pay its own

         11.03    Post-Closing Agreements of the BRI Partnership.


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

                  (b) Until the expiration of the period (the "No Transfer
Period") ending on the earlier of (I) such time as all of the Transferor Members
have redeemed all of the BRI Partnership Units received by the Transferor
Members 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 Membership 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 (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; and (iv) voluntary
transfers arising in connection with any financing or refinancing of the
Property, which shall include, without limitation, a mortgage, deed of trust, or
any other related financing liens or security interests, the parties
affirmatively acknowledging that there shall be no restriction on the financing
or refinancing of the Property by the BRI Partnership.

                  (c) 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 paid in cash at Closing by the party owing such amount
to the other party unless the Transferor Members have made an election to
receive BRI Partnership Units, in which event such proration 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) charges or prepayments under transferable Service
Contracts; and

                  (d) 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
Members 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 Members and the BRI Partnership shall cooperate in
the furnishing of all information and documentation necessary to prepare such
calculations. If the Transferor Members have elected to receive BRI Partnership
Units pursuant to Section 2.02, then prior to Closing, the Transferor Members
shall deliver to the BRI


                                      -43-
<PAGE>

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 Member, and
(ii) the number of BRI Partnership Units to be received by each Transferor
Member. 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 Members
and the Transferor Members hereby release the BRI Partnership from any such
obligation or liability.

         Subject to Section 12.04, all cash (including any escrow deposits)
shall be used by the Transferor Company to pay amounts payable by the Transferor
Company and/or distributed to the Transferor Members prior to Closing, and if
any of such cash applicable to preclosing periods is not removed from the
Transferor Company prior to Closing, the BRI Partnership shall hold such cash as
agent for the Transferor Members and refund such cash to the Transferor Members
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 Company shall distribute the
right to receive such rent to the Transferor Members immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Members in
collecting such rents. 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 Company 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 Members 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 Company 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 Members owe an amount
to the BRI Partnership, the Transferor Members shall have the right to elect to
adjust for such amounts owing by the Transferor Members to the BRI Partnership
in the form of BRI Partnership Units rather than


                                      -44-
<PAGE>

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 Members,
such amount shall be paid in the form of BRI Partnership Units rather than cash,
if the Transferor Members have elected under Section 2.02 to receive BRI
Partnership Units. The Transferor Members shall notify the BRI Partnership at
least seven (7) business days prior to the Closing Date of the manner in which
the Transferor Members shall have elected to settle adjustments under this
Section 12.

                                   SECTION 13
                                   ----------

                               FAILURE TO PERFORM
                               ------------------

         13.01 Defective Title or Condition. If the Transferor Members are
unable to give title or to contribute and transfer the Transferor Membership
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 Membership
Interests or the Property does not conform with the provisions hereof, the BRI
Partnership may elect by written notice given to the Transferor Members 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 Members can deliver to the Transferor Membership
Interests and the Property in its then condition and to deliver in exchange
therefor the Consideration Amount then required to be paid subject to reduction
of the Consideration Amount by the amounts required to remove all Monetary
Liens.

         13.03 Transferor Default. If the Transferor Company or any of the
Transferor Members default in the performance of their obligations under this
Agreement, or if any representation or warranty of the Transferor Company or the
Transferor Members is false or misleading (a "Transferor Default"), the BRI
Partnership shall be entitled to exercise any or all remedies as may be
available at law or in equity on account thereof, including, but not limited to,
an action for specific performance or an action for money damages. By their
execution hereof, Stephen M. Gorn and John B. Colvin ("Guarantors") hereby
guarantee the performance by the Transferor Company of all of its obligations
hereunder and, as part of such guaranty, shall be jointly and severally liable
with the Transferor Company of the payment of all damages to which BRI
Partnership may be entitled.

         13.04 The BRI Partnership's Default. If the BRI Partnership defaults in
performing any of its obligations hereunder, then the Transferor Members shall
be entitled to exercise any or all remedies as may be available at law or in
equity on account thereof, including, but not limited to, an action for specific
performance or an action for money damages.

                                 BROKERAGE FEES
                                 --------------

         14.01 Brokerage Fees. The Transferor Company 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 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 QPI and the Related
Entities in accordance with the provisions of the Related Agreements. 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 Company have any obligation to pay any
commission to APC.

         17.03 Related Agreements. Simultaneously herewith, the BRI Partnership
has entered into with various parties (the "Related Entities") 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 Questar Investment Corporation 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, this Agreement shall terminate automatically simultaneously
with the termination of any such Related Agreement 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
provisions of this Section 17.03 shall be of no further force or effect once
closing occurs under any one or more of the Related Agreements.


                                   SECTION 18
                                   ----------

                            MISCELLANEOUS PROVISIONS
                            ------------------------


         18.01. Assignment. Except as hereinafter provided, this Agreement may
not be assigned prior to Closing by either party hereto. The BRI Partnership
shall have the right to designate an entity affiliated with the BRI Partnership
to accept title to some of the Membership Interests, but the BRI Partnership
shall remain fully liable for the performance of all of its obligations
hereunder. The Transferor Members and the Transferor Company shall have the
right to collaterally assign their interests under this Agreement to a
construction lender providing construction financing for the Improvements (the
"Lender"). This Agreement shall be automatically subject and subordinate to the
mortgage, deed of trust and all other loan documents now or hereafter entered
into evidencing the loan and security of the Lender. If the Transferor Members
and Transferor Company so assign this Agreement, then the the BRI Partnership
agrees to enter into an agreement with the Lender (the "Tri Party Agreement")
providing that: (a) the BRI Partnership agrees to provide the Lender with
reasonable notice and opportunity to cure any default by the Transferor Members
or the Transferor Company hereunder; (b) the BRI Partnership agrees not to
modify or amend this Agreement without the prior written consent of Lender, (c)
the BRI Partnership, at the written request of Lender upon a default under the
loan, will pay the Base Consideration or such lesser amount as is required to
satisfy the loan directly to Lender provided that all of the conditions to
Closing provided herein have been satisfied; (d) the Lender agrees to recognize
the rights of BRI Partnership under this Agreement; (e) the BRI Partnership will
permit Lender to perform any obligations of the Transferor Company and
Transferor Members hereunder and will agree to recognize Lender as the
Transferor Company and the Transferor Members hereunder should Lender succeed to
the interest of the Transferor Company and Transferor Members, provided,
however, that, in such event, Lender's liability


                                      -50-
<PAGE>

under this Agreement shall be limited to its interest in the Transferor Company
and the Property; and further provided that (f) the BRI Partnership will have no
liability for payment of the Lender's loan or the performance of any obligations
under any of the loan documents other than the Tri-Party Agreement; and (g) the
amount to be paid to Lender shall be payable in cash only and not in BRI
Partnership Units and shall be limited to the amount provided in clause (c). The
parties acknowledge and agree that the Transferor Company is currently the owner
of land in addition to the Land (the "Additional Avalon Land") which is the
subject of a separate Development Contribution Agreement (the "Other Avalon
Agreement") between the BRI Partnership and the Transferor Company and
Transferor Members. To facilitate the transactions contemplated hereby and by
the Other Avalon Agreement, prior to the commencement of construction, the
Transferor Company will transfer either or both of the Land and the Additional
Land to a newly-formed limited partnership(s) or limited liability company(s)
such that the Land will be owned by one entity and the Additional Land will be
owned by another entity. At said time, the newly-formed entity(s) and its owners
will assume all of the obligations of either this Agreement or the Other Avalon
Agreement (whichever is applicable to the land it then owns) and the original
Transferor Company and Transferor Members shall be released from all liability
thereunder, and pursuant to instruments in form reasonably satisfactory to all
parties.

         18.02 Integration. This Agreement and the Schedules and Exhibits hereto
embody and constitute the entire understanding between the parties with respect
to the transactions contemplated herein, and all prior agreements,
understandings, representations and statements, oral or written, are merged into
this Agreement. Neither this Agreement nor any provision 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 termination is sought, and then only to the extent set forth in
such instrument.

         18.03 Governing Law. This Agreement shall be governed by, and construed

                                      -2-
<PAGE>


                                    SECTION 1
                                    ---------

             CONTRIBUTION OF MEMBERSHIP INTERESTS AND DUE DILIGENCE
             ------------------------------------------------------

         1.01 The Transferor Members shall contribute to the BRI Partnership,
and the BRI Partnership shall accept from the Transferor Members, in exchange
for either cash or BRI Partnership Units, and upon the terms and conditions set
forth in this Agreement, all of the Transferor Members' membership interests in
the Transferor Company (the "Transferor Membership Interests"). The percentage
of interest that each of the Transferor Members owns in the Transferor Company
is listed on Exhibit I. At the Closing (as defined in Section 3.01), the
Transferor Members shall, respectively, contribute, assign, transfer and deliver
the Transferor Membership Interests to the BRI Partnership, or its designees as
provided in Section 18.01 hereof, by an Assignment and Assumption of Membership
Interest in the form of Exhibit III attached hereto (the "Transferor
Assignment"). Immediately thereafter, the Transferor Members and the BRI
Partnership, or its designees, shall execute and deliver an Amended and Restated
Operating Agreement in the form of Exhibit IV attached hereto (the "Amended
Transferor Operating Agreement") and an Amended and Restated Articles of
Organization in the form of Exhibit V attached hereto (the "Amended Transferor
Company Articles") pursuant to which the BRI Partnership, or its designees,
shall be admitted and the Transferor Members shall withdraw, as the members of
the Transferor Company and be released of all liability thereunder, and the
terms of the Transferor Company shall be amended in accordance with the Amended
Transferor Operating Agreement.

         1.02 Property Title. Liriope: On or before September 22, 1997, the BRI
Partnership, at the BRI Partnership's sole cost, 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 Company promptly after its
receipt thereof. The Commitment shall insure fee simple title to the Property in
the sole name of the Transferor Company and shall be in the amount of
$7,622,857. 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 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 Company on or before October 1, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Company of any unacceptable exceptions as described above, the


                                      -3-
<PAGE>


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". Any easements or other agreements reasonably required
for the development and construction of the Property and the Improvements now or
hereafter entered into by the Transferor Company which are consistent with the
Plans and Specifications and, in the reasonable discretion of the BRI
Partnership, do not materially interfere with the intended use of the Property
nor materially affect the value of the Property, shall also constitute Permitted
Exceptions.

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at the BRI Partnership's sole cost, shall obtain an updated
commitment (the "Updated Commitment") for Title Insurance for an ALTA Form B
Owner's Title Insurance Policy from Lawyer's Title Insurance Corporation (the
"Title Insurer"). If any new exceptions to title appear in the Updated
Commitment that do not constitute Permitted Exceptions and that are unacceptable
to the BRI Partnership, in its reasonable discretion, the BRI Partnership may
notify the Transferor Company within thirty (30) days after the Completion Date
Notice.

         If any exceptions in the Commitment or the Updated Commitment are
unacceptable to the BRI Partnership in accordance with the foregoing provisions,
and the BRI Partnership timely notifies the Transferor Company in writing of
such fact as above provided, the Transferor Company shall have thirty (30) days
from the date the Transferor Company receives notice of such unacceptable
exceptions, at the option of the Transferor Company, to remove or cure such
exceptions, provided further, the Transferor Company 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 liens for real estate taxes and current water and sewer charges for the
fiscal year in which Closing occurs, 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 Company at Closing. The
Transferor Company shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Company, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Company will attempt to cure such unacceptable exceptions.
If the Transferor Company 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 Company 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 Company or
(ii) waive such exceptions and accept title subject thereto, in which event
there shall be a reduction in the Purchase Price (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 22, 1997, the BRI Partnership, at
the BRI Partnership's sole cost, shall obtain an as-built survey (the "Survey")
of the Land and the 


                                      -4-
<PAGE>


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 Company
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 Company on or before
October 1, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Company 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."

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at its sole cost and expense, shall obtain an updated
survey (the "Updated Survey") by a registered land surveyor (the "Surveyor")
acceptable to the BRI Partnership, which Updated 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
Updated Survey and the recorded legal description. The BRI Partnership shall
provide a copy of the Updated Survey to the Transferor Company promptly after
its receipt thereof. If any new matters appear on the Updated Survey that do not
constitute Permitted Exceptions, do not simply reflect the construction of the
Improvements in locations that do not encroach upon property lines, setback
lines or easements, and are unacceptable to the BRI Partnership in its
reasonable discretion, the BRI Partnership may notify the Transferor Company
within forty (40) days after the Substantial Completion Date Notice.



                                      -5-
<PAGE>


         If any survey matters are unacceptable to the BRI Partnership in
accordance with the foregoing provisions, and the BRI Partnership timely
notifies the Transferor Company in writing of such fact as above provided, the
Transferor Company shall have thirty (30) days from the date the Transferor
Company receives notice of such unacceptable survey matters, at the option of
the Transferor Company, to cure such unacceptable survey matters. The Transferor
Company shall be deemed to have refused to cure any unacceptable survey matters
unless the Transferor Company, within ten (10) days after receipt of notice from
the BRI Partnership, shall notify the BRI Partnership in writing that the
Transferor Company will attempt to cure such unacceptable survey matters. If the
Transferor Company 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 Company 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 Company 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     Construction and Inspection.

                  (a) Plans and Specifications. Prior to the date of this
Agreement, Transferor Company has delivered to BRI Partnership true, correct and
complete copies of the Plans and Specifications for the construction of the
Improvements as set forth on Schedule C attached hereto.

                  (b) Transferor Company to Construct Improvements. Transferor
Company shall, at Transferor Company's expense, obtain all permits and construct
the Improvements on the Land in accordance with the Plans and Specifications, as
the same may be modified by change order in accordance with this Agreement. All
work shall be done in a good and workmanlike manner using new, good quality
materials, free of all defects and in compliance with all Codes (as defined in
Section 5.21), permits, approvals, title restrictions and insurance
requirements. Transferor Company shall obtain builder's risk insurance on the
Improvements in the amount of the construction cost of those buildings from time
to time for which construction has commenced. Transferor Company shall deliver a
certificate of such insurance to BRI Partnership. Transferor Company shall
maintain such insurance in force and effect through the course of construction
and until Closing hereunder.

                  (c) Inspection of Construction; Correction of Defects. BRI
Partnership and its engineers, consultants and agents may inspect the
construction of the Improvements from time to time during the course of
construction upon reasonable notice to the Transferor Company. After receipt
from the Transferor Company of written notice that the requirements of Section
3.02(a)(i) and (ii) have been satisfied (the "Inspection Notice"), BRI
Partnership and its engineers, consultants and agents shall inspect the
construction of the Improvements upon reasonable notice to Transferor Company to
determine whether such construction is completed in accordance with the Plans
and Specifications. The parties acknowledge that the Transferor Company has


                                      -6-
<PAGE>


delivered the Inspection Notice as of September 8, 1997. On or before October 7,
1997, BRI Partnership will give written notice to Transferor Company of any
nonconformities with the Plans and Specifications and defects or deficiencies in
construction identified by BRI Partnership. Unless Transferor Company disagrees
with BRI Partnership, which disagreement shall be expressed by giving written
notice to the BRI Partnership stating the basis for said disagreements, within
10 days after such BRI Partnership notice, Transferor Company, at Transferor
Company's expense, shall commence to correct, repair or replace any such
nonconformities, defects or deficiencies and shall diligently continue
thereafter until completion of such corrections, repairs or replacements, and,
if such deficiencies are of such a magnitude that Closing would not otherwise be
required to occur under Section 3.02 and Section 5.30, the Closing Date shall be
extended until the deficiencies are corrected. Any dispute shall be resolved by
arbitration in accordance with Section 3.02.

                  (d) Change Orders. The Transferor Company shall not change or
modify the Plans and Specifications without prior written approval of the BRI
Partnership, such approval not to be unreasonably withheld, provided, however
that the following changes shall not require BRI Partnership's approval: (i)
changes required by the construction lender or governmental authorities, and
(ii) changes in the design of the Improvements resulting in a decrease or
increase in construction cost by less than $100,000 for an individual change and
less than $250,000 in the aggregate. The Transferor Company shall give written
notice to BRI Partnership of all proposed changes to the Plans and
Specifications by sending a complete copy of the change, together with copies of
any plans or drawings related thereto. BRI Partnership shall give its written
approval or disapproval within five (5) business days thereafter. If BRI
Partnership disapproves any such change, the Transferor Company shall not
implement same.

                  (e) Completion. The Transferor Company shall diligently
attempt to complete construction of the Improvements in accordance with the
Plans and Specifications, as modified in accordance with this Agreement, and in
compliance with all Codes (as defined in Section 5.21 hereof) by December 31,
2000 (the "Scheduled Completion Date"). For purposes of this Agreement, the
"Completion Date" shall be the date upon which all of the Closing Conditions
shall have been satisfied as set forth in Section 3.02.

                  (f) Force Majeure. In the event that the Transferor Company is
delayed in the commencement or completion of construction of the Improvements by
acts of God, war, civil commotion, fire, flood or other casualty, labor
difficulties, strikes, shortages of labor, materials or equipment, undue delay
in action by governmental authorities, governmental or utility company refusal
to issue building, construction, utility, occupancy or other permits or
approvals, water, sewer or other utility moratorium (including enforcement of
the requirements of any adequate public facilities ordinance) or other causes
beyond the Transferor Company's reasonable control (a "Force Majeure Event"),
the Scheduled Completion Date shall be extended for the period of delay, not to
exceed 12 months. If a Force Majeure Event continues in effect for a period in
excess of 12 months, during which construction is delayed, then the Transferor
Company may, by notice to BRI Partnership terminate this Agreement, in which
event the 


                                      -7-
<PAGE>


Deposit shall be returned to the BRI Partnership and neither party shall have
any further liability to the other hereunder. In addition, simultaneously with
closing under the Related Agreements, the Transferor Company shall execute and
deliver to BRI Partnership the Right of First Offer Agreement attached hereto as
Exhibit IX, which Right of First Offer Agreement shall contain, among other
provisions a Right of First Refusal which provides: (a) that the BRI Partnership
shall have a right of first refusal to purchase the Property following the
termination of this Agreement pursuant to this Section 1.04(f), (b) BRI
Partnership shall have a period of 15 business days, following receipt of a bona
fide third party letter of intent to purchase the Property, to agree to purchase
the Property on the same terms and conditions as set forth in the letter of
intent, and (c) such Right of First Offer Agreement shall be subordinate to any
mortgage or deed of trust securing construction financing on the Property.

         1.05     Environmental Due Diligence Inspection.

                  (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 Company,
inspect the Property to determine the presence of any Hazardous Materials (as
defined in Section 5.20) and the compliance of the Property with Environmental
Laws (as defined in Section 5.20) 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 Company 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 Company in this Agreement. Should the BRI Partnership decide, in its
reasonable judgment, that there exists an environmental risk with respect to the
Property (excluding such items as asbestos roof shingles, asbestos floor tile
and mastic, PCBs in electric light ballasts, HCFCs or CFSs in HVAC units, the
presence of usual and customary cleaning and maintenance supplies and similar
items that are typically handled through the adoption of appropriate operations
policies), 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
Company 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 1.05. The BRI Partnership shall pay when due all fees and expenses
incurred in the performance of the Environmental Inspection performed at its
request.



                                      -8-
<PAGE>


                  (b) From and after the date of this Agreement, the Transferor
Company shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Company'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 Company's financial records relating to the Property
have been audited, the Transferor Company agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Company shall provide the
BRI Partnership with such information as the Transferor Company 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 Company, all taxes and utility payments made 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 1.05(b) 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 Company if the Closing does not occur.

                  (c) The BRI Partnership shall indemnify the Transferor Members
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
Members 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 Members 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 1.05(c) shall survive the Closing
or any termination of this Agreement; provided, however, that no claim by the
Transferor Members under this Section 1.05(c) 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 Members 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 Members hereunder.

         1.06 Tax Treatment. The parties intend that, to the extent the
Transferor Members receive BRI Partnership Units as the consideration for the
contribution of the Transferor Membership Interests by the Transferor Members to
the BRI Partnership in accordance with Section 1.01 of this Agreement, such
contribution shall be treated for federal (and applicable


                                      -9-
<PAGE>


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 Members agree to report such transaction for federal and applicable
state income tax purposes consistently with the intent set forth in this Section
1.06.

                                    SECTION 2
                                    ---------

                                  CONSIDERATION
                                  -------------

         The consideration for the Membership Interests (the "Consideration
Amount"), subject to the adjustments contained in Section 12 of this Agreement,
shall be determined pursuant to the provisions of Section 2.04, and shall be
paid by the the BRI Partnership to the Transferor Members in the following
manner:

         2.01     Deposit.

                  (a) Simultaneously with the execution of this Agreement, the
the BRI Partnership shall deliver to Lawyers Title Insurance Corporation (the
"Escrow Agent") the sum of ONE DOLLAR ($1.00) (the "Initial Deposit") by check
(subject to collection) as a Deposit to be held in an interest-bearing escrow
account on account of the Consideration Amount. Said sum, together with any
interest earned thereon, is hereinafter called the "Deposit."

                  (b) At the Closing, the Deposit shall be returned by the
Escrow Agent to BRI Partnership.

         2.02 Balance. At the Closing, the BRI Partnership shall deliver to the
Transferor Members the Base Consideration, plus, if then due, any Additional
Consideration Installments, subject to the adjustments described in Section 12
of this Agreement by federal wired funds. Prior to any delivery to the
Transferor Members of the Base Consideration, there shall be deducted from the
Base Consideration an amount equal to the sum required to pay off the
Construction Loan in full and to remove all other Monetary Liens and
simultaneously with the Closing, the BRI Partnership shall pay off the
Construction Loan. At the Transferor members' option, to be exercised
irrevocably by written notice to the BRI Partnership given at least 15 days
prior to the satisfaction of the Closing Conditions, all or a portion of the
Consideration Amount shall be delivered to the Transferor Members in the form of
BRI Partnership Units in the BRI Partnership. If the Transferor Members exercise
such option, then the number of BRI Partnership Units, the rights and
limitations upon such units and the method by which the units are delivered to
the Transferor Members at Closing shall be as provided in Sections 2.02 (a), (b)
and (c) below. If the Transferor Members do not exercise the foregoing option in
a timely manner, all consideration payable under this Agreement shall be paid in
cash by federal wired funds and the following Sections of this Agreement shall
be, without further action by any party, null and void and without any further
force or effect upon the parties: 1.06, 2.02(a) through (c),


                                      -10-
<PAGE>


5.34, 6.03, 6.05, 6.06, 6.08, 6.09, 6.10, 6.12 through 6.16, 10.01(e), 10.04,
11.01(a) (ii), (iii) and (iv) and 11.01(d) (last sentence only), 11.03 and
12.04.

                  (a) The number of BRI Partnership Units to be issued to the
Transferor Members at Closing shall be that number determined by dividing the
portion of the Consideration Amount to be paid in BRI Partnership Units to each
Transferor Member by the value of one BRI Partnership Unit. The parties agree
that, for purposes of this Agreement, the value of each BRI Partnership Unit
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 ten (10) business days prior to the day which
is five (5) business days before the Closing. If the calculation provided for
above results in a fraction of a BRI Partnership Unit to be delivered to a
Transferor Member, the number of BRI Partnership Units to be delivered shall be
rounded up or down to the nearest whole number of BRI Partnership Units.

         Attached hereto as Exhibit I is a schedule (the "Transferor Allocation
Schedule") prepared by the Transferor Members setting forth (i) the name of each
Transferor Member, and (ii) the percentage interest of each Transferor Member,
together with an investor questionnaire in the form attached hereto as Exhibit 5
(the "BRI Questionnaire") for each Transferor Member. In the event that any
Transferor Member 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 Members all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Members
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Members 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 Members in accordance with the election made by the Transferor
Members pursuant to Section 2.02. The BRI Partnership shall have no obligation
or liability with respect to the preparation or accuracy of the Transferor
Allocation Schedule.

                  (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 any Transferor Member 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 Member 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 Members and Berkshire 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


                                      -11-
<PAGE>


Partnership shall deliver to the Transferor Members a certified copy of the
Registration Rights Agreement.

                  (c) The Transferor Members, 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, 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 this Section, 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 Members in the event of a
decrease or increase in the market value of the common stock of BRI.

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

         2.04 Calculation of Consideration Amount. The Consideration Amount for
the Transferor Membership Interests shall consist of a base consideration amount
("Base Consideration") plus additional consideration installments ("Additional
Consideration Installments").

                  (a) The Base Consideration for the Transferor Membership
Interests shall be Six Million, Fourteen Thousand, Seven Hundred Seventeen
Dollars ($6,014,717), provided, however, that, it shall be a condition of
Closing that, on the date of Closing, the value of the Property (determined by
dividing Stabilized NOI for the month preceding the date of Closing by the Cap
Rate, as such terms are hereinafter defined) is not less than the Base
Consideration, and if such amount is less than the Base Consideration, Closing
shall be extended until such time as such calculation is not less than the Base
Consideration.

                  (b) In addition to the Base Consideration, the BRI Partnership
shall pay one or more additional consideration installments (the "Additional
Consideration Installments"), if any, on a quarterly basis with the first
payment, if then due, on the date of Closing and on the first day of each
quarter (defined as a period of three full calendar months, plus, for the first
quarter, any partial calendar month after the date of Closing) thereafter for a
total of 18 full calendar months after the Closing (the "Earn Out Period"). As
of the Closing and as of the first day of each quarter thereafter, Stabilized
NOI shall be determined as provided below, and each Additional Consideration
Installment, if any, will be equal to the Stabilized NOI divided by 8.75% (the
"Cap Rate") and then reduced by the Base Consideration and any prior Additional
Consideration Installments. The maximum Consideration Amount, (i.e. the sum of
the Base Consideration plus all Additional Consideration Installments) shall not
exceed Seven Million, Six Hundred Twenty-Two Thousand, Eight Hundred Fifty-Seven
Dollars ($7,622,857).

                  (c) Stabilized NOI shall be calculated for purposes of
determining both the Base Consideration and the Additional Consideration
Installments as follows: 12 times the 


                                      -12-
<PAGE>


monthly actual income for the Property, (provided that if occupancy rates exceed
95%, then actual income shall be calculated as if the Property had an occupancy
rate of 95%) for the month preceding the payment date less Two Hundred
Twenty-Seven Thousand, One Hundred Dollars ($227,100) (representing the
agreed-upon annual Projected Operating Expenses for the Property), provided
that, on the first anniversary of the date of Closing under this Agreement, the
Projected Operating Expenses shall be adjusted by the percentage change in the
CPI-U, U.S. Cities Average for the period from the date of Closing under this
Agreement until the anniversary date.

                                    SECTION 3
                                    ---------

                                   THE CLOSING
                                   -----------

         3.01 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
in Washington, D.C., or such other place as the Transferor Company and the BRI
Partnership shall mutually agree. The "Time of Closing" shall be on that date
specified in Section 3.02 at which 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
Members 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 Members. It is agreed that time is of the essence of this
Agreement.

         3.02 Closing under this Agreement shall occur on the first business day
of the month after the Transferor Members have given to the BRI Partnership 60
days prior notice (the "Substantial Completion Date Notice") of the occurrence
of the last to occur of (a) the substantial completion of construction of the
Property excluding punch-list items not affecting occupancy (provided Transferor
Members shall thereafter complete all punch-list items at no expense to the BRI
Partnership within 30 days after Closing or within such additional time as may
be reasonably required) ("Completion Date") as evidenced by satisfaction of each
of the following conditions (the "Closing Conditions"): (i) final certificates
of occupancy issued by the appropriate governmental authority, and (ii) a
certificate of substantial completion issued by Questar Builders, Inc. or such
affiliate of Transferor Members as Transferor Members may designate to be the
general contractor for construction of the Improvements ("Questar Builders")
certifying that the Improvements have been substantially completed in accordance
with the Plans and Specifications and all Codes, as such may be modified from
time to time by the Transferor Company in accordance with this Agreement, or (b)
the Stabilization Date. If a dispute shall exist as to whether substantial
completion has occurred, the dispute shall be promptly submitted to binding
arbitration by a qualified third party mutually acceptable to the parties or, if

Company and except as shown on the Plans and Specifications, there are no

agrees as follows:

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

                  (c) Such Transferor Member acknowledges and agrees that, for
the reasons set forth in Sections 5.34(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 such Transferor Member 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 Member 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 Member acknowledges, represents and agrees that


                                      -24-

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, 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
Member 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.

(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 Member 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

                  and will not be registered or qualified under any other
                  applicable securities laws;

                           (ii) any shares of common stock issued upon exchange

control, BRI Partnership agrees that Patrick Connelly, currently a vice
president of The Questar Management Company, shall remain employed by the
Management Company until the expiration of the Earn Out Period, his principal
place of employment shall remain at the principal regional office of the
Transferor Company and he shall devote such efforts to the Property as the

to attempt to recruit Patrick Connelly as their full-time employee.

                  (b) any willful action by the Transferor Company which would
render any of representations and warranties contained in Section 5 hereof

or to better vest in the Transferor Members title to the BRI Partnership Units.
The provisions of this Section 11.01(h) shall survive the Closing indefinitely.

         11.02 BRI Partnership's Expenses. The BRI Partnership shall pay its own
counsel fees, and all (i) Title Insurance and Survey costs, (ii) escrow and
recording costs, (iii) transfer taxes and documentary stamps, if any, (iv) UCC
search costs and (v) all other Closing costs.

         11.03    Post-Closing Agreements of the BRI Partnership.

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

                  (b) Until the expiration of the period (the "No Transfer
Period") ending on the earlier of (I) such time as all of the Transferor Members
have redeemed all of the BRI Partnership Units received by the Transferor
Members 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 Membership 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 (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; and (iv) voluntary
transfers arising in connection with any financing or refinancing of the
Property, which shall include, without limitation, a mortgage, deed of trust, or
any other related financing liens or security interests, the parties
affirmatively acknowledging that there shall be no restriction on the financing
or refinancing of the Property by the BRI Partnership.

                  (c) 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 paid in cash at Closing by the party owing such amount
to the other party unless the Transferor Members have made an election to
receive BRI Partnership Units, in which event such proration 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) charges or prepayments under transferable Service
Contracts; and

                  (d) 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
Members 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 Members and the BRI Partnership shall cooperate in
the furnishing of all information and documentation necessary to prepare such
calculations. If the Transferor Members have elected to receive BRI Partnership
Units pursuant to Section 2.02, then prior to Closing, the Transferor Members
shall deliver to the BRI 


                                      -43-
<PAGE>


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 Member, and
(ii) the number of BRI Partnership Units to be received by each Transferor
Member. 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 Members
and the Transferor Members hereby release the BRI Partnership from any such
obligation or liability.

         Subject to Section 12.04, all cash (including any escrow deposits)
shall be used by the Transferor Company to pay amounts payable by the Transferor
Company and/or distributed to the Transferor Members prior to Closing, and if
any of such cash applicable to preclosing periods is not removed from the
Transferor Company prior to Closing, the BRI Partnership shall hold such cash as
agent for the Transferor Members and refund such cash to the Transferor Members
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 Company shall distribute the
right to receive such rent to the Transferor Members immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Members in
collecting such rents. 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 Company 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 Members 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 Company 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 Members owe an amount
to the BRI Partnership, the Transferor Members shall have the right to elect to
adjust for such amounts owing by the Transferor Members to the BRI Partnership
in the form of BRI Partnership Units rather than


                                      -44-
<PAGE>


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 Members,
such amount shall be paid in the form of BRI Partnership Units rather than cash,
if the Transferor Members have elected under Section 2.02 to receive BRI
Partnership Units. The Transferor Members shall notify the BRI Partnership at
least seven (7) business days prior to the Closing Date of the manner in which
the Transferor Members shall have elected to settle adjustments under this
Section 12.

                                   SECTION 13
                                   ----------

                               FAILURE TO PERFORM
                               ------------------

         13.01 Defective Title or Condition. If the Transferor Members are
unable to give title or to contribute and transfer the Transferor Membership
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 Membership
Interests or the Property does not conform with the provisions hereof, the BRI
Partnership may elect by written notice given to the Transferor Members 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 Members can deliver to the Transferor Membership
Interests and the Property in its then condition and to deliver in exchange
therefor the Consideration Amount then required to be paid subject to reduction
of the Consideration Amount by the amounts required to remove all Monetary
Liens.

         13.03 Transferor Default. If the Transferor Company or any of the
Transferor Members default in the performance of their obligations under this
Agreement, or if any representation or warranty of the Transferor Company or the
Transferor Members is false or misleading (a "Transferor Default"), the BRI
Partnership shall be entitled to exercise any or all remedies as may be
available at law or in equity on account thereof, including, but not limited to,
an action for specific performance or an action for money damages. By their
execution hereof, Stephen M. Gorn and John B. Colvin ("Guarantors") hereby
guarantee the performance by the Transferor Company of all of its obligations
hereunder and, as part of such guaranty, shall be jointly and severally liable
with the Transferor Company of the payment of all damages to which BRI
Partnership may be entitled.

         13.04 The BRI Partnership's Default. If the BRI Partnership defaults in
performing any of its obligations hereunder, then the Transferor Members shall
be entitled to exercise any or all remedies as may be available at law or in
equity on account thereof, including, but not limited to, an action for specific
performance or an action for money damages.

                                 BROKERAGE FEES
                                 --------------

         14.01 Brokerage Fees. The Transferor Company 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 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 QPI and the Related
Entities in accordance with the provisions of the Related Agreements. 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 Company have any obligation to pay any
commission to APC.

the rights of BRI Partnership under this Agreement; (e) the BRI Partnership will

however, that, in such event, Lender's liability

                                      -2-

                                    SECTION 1
                                    ---------

             CONTRIBUTION OF MEMBERSHIP INTERESTS AND DUE DILIGENCE
             ------------------------------------------------------

         1.01 The Transferor Members shall contribute to the BRI Partnership,
and the BRI Partnership shall accept from the Transferor Members, in exchange
for either cash or BRI Partnership Units, and upon the terms and conditions set
forth in this Agreement, all of the Transferor Members' membership interests in
the Transferor Company (the "Transferor Membership Interests"). The percentage
of interest that each of the Transferor Members owns in the Transferor Company
is listed on Exhibit I. At the Closing (as defined in Section 3.01), the
Transferor Members shall, respectively, contribute, assign, transfer and deliver
the Transferor Membership Interests to the BRI Partnership, or its designees as
provided in Section 18.01 hereof, by an Assignment and Assumption of Membership
Interest in the form of Exhibit III attached hereto (the "Transferor
Assignment"). Immediately thereafter, the Transferor Members and the BRI
Partnership, or its designees, shall execute and deliver an Amended and Restated
Operating Agreement in the form of Exhibit IV attached hereto (the "Amended
Transferor Operating Agreement") and an Amended and Restated Articles of
Organization in the form of Exhibit V attached hereto (the "Amended Transferor
Company Articles") pursuant to which the BRI Partnership, or its designees,
shall be admitted and the Transferor Members shall withdraw, as the members of
the Transferor Company and be released of all liability thereunder, and the
terms of the Transferor Company shall be amended in accordance with the Amended
Transferor Operating Agreement.

         1.02 Property Title. On or before September 22, 1997, the Transferor
Members shall deliver to the BRI Partnership a copy of the Transferor Company's
existing title insurance commitment or policy (the "Commitment") 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").

         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 Company on or before October 1, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Company 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". Any easements or other agreements reasonably required
for the development and construction of the Property and the Improvements now or
hereafter entered into by the Transferor Company which are consistent with the
Plans and Specifications and, in the reasonable discretion of the BRI
Partnership, do not materially interfere with the intended use of the Property
nor materially affect the value of the Property, shall also constitute Permitted
Exceptions.


                                      -3-
<PAGE>

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at the BRI Partnership's sole cost, shall obtain a new
commitment (the "Updated Commitment") for Title Insurance for an ALTA Form B
Owner's Title Insurance Policy from Lawyer's Title Insurance Corporation (the
"Title Insurer"). The Updated Commitment shall insure fee simple title to the
Property in the sole name of the Transferor Company and shall be in the amount
of $25,508,709. The Updated 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 and are available under the law of the state in
which the Property is located. If any new exceptions to title appear in the
Updated Commitment that do not constitute Permitted Exceptions and that are
unacceptable to the BRI Partnership, in its reasonable discretion, the BRI
Partnership may notify the Transferor Company within thirty (30) days after the
Completion Date Notice.

         If any exceptions in the Commitment or the Updated Commitment are
unacceptable to the BRI Partnership in accordance with the foregoing provisions,
and the BRI Partnership timely notifies the Transferor Company in writing of
such fact as above provided, the Transferor Company shall have thirty (30) days
from the date the Transferor Company receives notice of such unacceptable
exceptions, at the option of the Transferor Company, to remove or cure such
exceptions, provided further, the Transferor Company 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 liens for real estate taxes and current water and sewer charges for the
fiscal year in which Closing occurs, 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 Company at Closing. The
Transferor Company shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Company, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Company will attempt to cure such unacceptable exceptions.
If the Transferor Company 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 Company 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 Company or
(ii) waive such exceptions and accept title subject thereto, in which event
there shall be a reduction in the Purchase Price (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 22, 1997, the Transferor Company
shall provide to the BRI Partnership a copy of its existing survey (the
"Survey") of the Land and any Improvements.]


                                      -4-
<PAGE>


         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 Company on or before
October 1, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Company 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."

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at its sole cost and expense, shall obtain an updated
survey (the "Updated Survey") by a registered land surveyor (the "Surveyor")
acceptable to the BRI Partnership, which Updated 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
Updated Survey and the recorded legal description. The BRI Partnership shall
provide a copy of the Updated Survey to the Transferor Company promptly after
its receipt thereof. If any new matters appear on the Updated Survey that do not
constitute Permitted Exceptions, do not simply reflect the construction of the
Improvements in locations that do not encroach upon property lines, setback
lines or easements, and are unacceptable to the BRI Partnership in its
reasonable discretion, the BRI Partnership may notify the Transferor Company
within forty (40) days after the Substantial Completion Date Notice.

         If any survey matters are unacceptable to the BRI Partnership in
accordance with the foregoing provisions, and the BRI Partnership timely
notifies the Transferor Company in writing of such fact as above provided, the
Transferor Company shall have thirty (30) days from the date the Transferor
Company receives notice of such unacceptable survey matters, at the option of
the Transferor Company, to cure such unacceptable survey matters. The Transferor
Company shall be deemed to have refused to cure any unacceptable survey matters
unless the Transferor Company, within ten (10) days after receipt of notice from
the BRI Partnership, shall notify the BRI Partnership in writing that the
Transferor Company will attempt to cure such unacceptable survey matters. If the
Transferor Company 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 Company 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 


                                      -5-
<PAGE>


Transferor Company 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     Construction and Inspection.

                  (a) Plans and Specifications. Prior to the date of this
Agreement, Transferor Company has delivered to BRI Partnership true, correct and
complete copies of the Plans and Specifications for the construction of the
Improvements as set forth on Schedule C attached hereto.

                  (b) Transferor Company to Construct Improvements. Transferor
Company shall, at Transferor Company's expense, obtain all permits and construct
the Improvements on the Land in accordance with the Plans and Specifications, as
the same may be modified by change order in accordance with this Agreement. All
work shall be done in a good and workmanlike manner using new, good quality
materials, free of all defects and in compliance with all Codes (as defined in
Section 5.21), permits, approvals, title restrictions and insurance
requirements. Transferor Company shall obtain builder's risk insurance on the
Improvements in the amount of the construction cost of those buildings from time
to time for which construction has commenced. Transferor Company shall deliver a
certificate of such insurance to BRI Partnership. Transferor Company shall
maintain such insurance in force and effect through the course of construction
and until Closing hereunder.

                  (c) Inspection of Construction; Correction of Defects. BRI
Partnership and its engineers, consultants and agents may inspect the
construction of the Improvements from time to time during the course of
construction upon reasonable notice to the Transferor Company. After receipt
from the Transferor Company of written notice that the requirements of Section
3.02(a)(i) and (ii) have been satisfied (the "Inspection Notice"), BRI
Partnership and its engineers, consultants and agents shall inspect the
construction of the Improvements upon reasonable notice to Transferor Company to
determine whether such construction is completed in accordance with the Plans
and Specifications. Within 30 days after the Inspection Notice, BRI Partnership
will give written notice to Transferor Company of any nonconformities with the
Plans and Specifications and defects or deficiencies in construction identified
by BRI Partnership. Unless Transferor Company disagrees with BRI Partnership,
which disagreement shall be expressed by giving written notice to the BRI
Partnership stating the basis for said disagreements, within 10 days after such
BRI Partnership notice, Transferor Company, at Transferor Company's expense,
shall commence to correct, repair or replace any such nonconformities, defects
or deficiencies and shall diligently continue thereafter until completion of
such corrections, repairs or replacements, and, if such deficiencies are of such
a magnitude that Closing would not otherwise be required to occur under Section
3.02 and Section 5.30, the Closing Date shall be extended until the deficiencies
are corrected. Any dispute shall be resolved by arbitration in accordance with
Section 3.02.


                                      -6-
<PAGE>


                  (d) Change Orders. The Transferor Company shall not change or
modify the Plans and Specifications without prior written approval of the BRI
Partnership, such approval not to be unreasonably withheld, provided, however
that the following changes shall not require BRI Partnership's approval: (i)
changes required by the construction lender or governmental authorities, and
(ii) changes in the design of the Improvements resulting in a decrease or
increase in construction cost by less than $100,000 for an individual change and
less than $250,000 in the aggregate. The Transferor Company shall give written
notice to BRI Partnership of all proposed changes to the Plans and
Specifications by sending a complete copy of the change, together with copies of
any plans or drawings related thereto. BRI Partnership shall give its written
approval or disapproval within five (5) business days thereafter. If BRI
Partnership disapproves any such change, the Transferor Company shall not
implement same.

                  (e) Completion. The Transferor Company shall diligently
attempt to complete construction of the Improvements in accordance with the
Plans and Specifications, as modified in accordance with this Agreement, and in
compliance with all Codes (as defined in Section 5.21 hereof) by December 31,
2001 (the "Scheduled Completion Date"). For purposes of this Agreement, the
"Completion Date" shall be the date upon which all of the Closing Conditions
shall have been satisfied as set forth in Section 3.02.

                  (f) Force Majeure. In the event that the Transferor Company is
delayed in the commencement or completion of construction of the Improvements by
acts of God, war, civil commotion, fire, flood or other casualty, labor
difficulties, strikes, shortages of labor, materials or equipment, undue delay
in action by governmental authorities, governmental or utility company refusal
to issue building, construction, utility, occupancy or other permits or
approvals, water, sewer or other utility moratorium (including enforcement of
the requirements of any adequate public facilities ordinance) or other causes
beyond the Transferor Company's reasonable control (a "Force Majeure Event"),
the Scheduled Completion Date shall be extended for the period of delay, not to
exceed 12 months. If a Force Majeure Event continues in effect for a period in
excess of 12 months, during which construction is delayed, then the Transferor
Company may, by notice to BRI Partnership terminate this Agreement, in which
event the Deposit shall be returned to the BRI Partnership and neither party
shall have any further liability to the other hereunder. In addition,
simultaneously with closing under the Related Agreements, the Transferor Company
shall execute and deliver to BRI Partnership the Right of First Offer Agreement
attached hereto as Exhibit IX, which Right of First Offer Agreement shall
contain, among other provisions a Right of First Refusal which provides: (a)
that the BRI Partnership shall have a right of first refusal to purchase the
Property following the termination of this Agreement pursuant to this Section
1.04(f), (b) BRI Partnership shall have a period of 15 business days, following
receipt of a bona fide third party letter of intent to purchase the Property, to
agree to purchase the Property on the same terms and conditions as set forth in
the letter of intent, and (c) such Right of First Offer Agreement shall be
subordinate to any mortgage or deed of trust securing construction financing on
the Property.

         1.05     Environmental Due Diligence Inspection.

                  (a) On or before September 22, 1997, the Transferor Company
shall deliver to the BRI Partnership a copy of its environmental report for the
Property (the "Initial Environmental Report"). Should the BRI Partnership
decide, in its sole judgment, during the period up to and including October 1,
1997 (the "Due Diligence Period") that the Initial Environmental Report is
unsatisfactory, the BRI Partnership shall have the right to terminate this
Agreement by giving written notice of its election to do so 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. 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 the period expiring
30 days after the Substantial Completion Date Notice during regular business
hours and on reasonable prior notice to the Transferor Company, inspect the
Property to determine the presence of any Hazardous Materials (as defined in
Section 5.20) and the compliance of the Property with Environmental Laws (as
defined in Section 5.20) 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 Company 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 Company in this Agreement. Should the BRI Partnership decide, in its
reasonable judgment, that there exists an environmental risk with respect to the
Property (excluding such items as asbestos roof shingles, asbestos floor tile
and mastic, PCBs in electric light ballasts, HCFCs or CFSs in HVAC units, the
presence of usual and customary cleaning and maintenance supplies and similar
items that are typically handled through the adoption of appropriate operations
policies), during the period expiring 30 days after the Substantial Completion
Date Notice 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 Company on or before 30 days
after the Substantial Completion Date, and upon the giving of such notice this
Agreement shall be of no further force or effect. Notwithstanding the foregoing,
the BRI Partnership may not disapprove or object to any matter disclosed by the
Environmental Inspection that was disclosed in the Initial Environmental Report.
If the BRI Partnership shall fail to exercise such termination right within any
such 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 1.05.
The BRI Partnership shall pay when due all fees and expenses incurred in the
performance of the Environmental Inspection performed at its request.

<PAGE>


                  (b) From and after the date of this Agreement, the Transferor
Company shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Company'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 Company's financial records relating to the Property
have been audited, the Transferor Company agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Company shall provide the
BRI Partnership with such information as the Transferor Company 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 Company, all taxes and utility payments made 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 1.05(b) 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 Company if the Closing does not occur.

                  (c) The BRI Partnership shall indemnify the Transferor Members
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
Members 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 Members 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 1.05(c) shall survive the Closing
or any termination of this Agreement; provided, however, that no claim by the
Transferor Members under this Section 1.05(c) 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 Members 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 Members hereunder.

         1.06 Tax Treatment. The parties intend that, to the extent the
Transferor Members receive BRI Partnership Units as the consideration for the
contribution of the Transferor Membership Interests by the Transferor Members to
the BRI Partnership in accordance with Section 1.01 of this Agreement, such
contribution shall be treated for federal (and applicable 


                                      -9-
<PAGE>


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 Members agree to report such transaction for federal and applicable
state income tax purposes consistently with the intent set forth in this Section
1.06.

                                    SECTION 2
                                    ---------

                                  CONSIDERATION
                                  -------------

         The consideration for the Membership Interests (the "Consideration
Amount"), subject to the adjustments contained in Section 12 of this Agreement,
shall be determined pursuant to the provisions of Section 2.04, and shall be
paid by the the BRI Partnership to the Transferor Members in the following
manner:

         2.01     Deposit.

                  (a) Simultaneously with the execution of this Agreement, the
the BRI Partnership shall deliver to Lawyers Title Insurance Corporation (the
"Escrow Agent") the sum of ONE DOLLAR ($1.00) (the "Initial Deposit") by check
(subject to collection) as a Deposit to be held in an interest-bearing escrow
account on account of the Consideration Amount. Said sum, together with any
interest earned thereon, is hereinafter called the "Deposit."

                  (b) At the Closing, the Deposit shall be returned by the
Escrow Agent to BRI Partnership.

         2.02 Balance. At the Closing, the BRI Partnership shall deliver to the
Transferor Members the Base Consideration, plus, if then due, any Additional
Consideration Installments, subject to the adjustments described in Section 12
of this Agreement by federal wired funds. Prior to any delivery to the
Transferor Members of the Base Consideration, there shall be deducted from the
Base Consideration an amount equal to the sum required to pay off the
Construction Loan in full and to remove all other Monetary Liens and
simultaneously with the Closing, the BRI Partnership shall pay off the
Construction Loan. At the Transferor members' option, to be exercised
irrevocably by written notice to the BRI Partnership given at least 15 days
prior to the satisfaction of the Closing Conditions, all or a portion of the
Consideration Amount shall be delivered to the Transferor Members in the form of
BRI Partnership Units in the BRI Partnership. If the Transferor Members exercise
such option, then the number of BRI Partnership Units, the rights and
limitations upon such units and the method by which the units are delivered to
the Transferor Members at Closing shall be as provided in Sections 2.02 (a), (b)
and (c) below. If the Transferor Members do not exercise the foregoing option in
a timely manner, all consideration payable under this Agreement shall be paid in
cash by federal wired funds and the following Sections of this Agreement shall
be, without further action by any party, null and void and without any further
force or effect upon the parties: 1.06, 2.02(a) through (c),


                                      -10-
<PAGE>


5.34, 6.03, 6.05, 6.06, 6.08, 6.09, 6.10, 6.12 through 6.16, 10.01(e), 10.04,
11.01(a) (ii), (iii) and (iv) and 11.01(d) (last sentence only), 11.03 and
12.04.

                  (a) The number of BRI Partnership Units to be issued to the
Transferor Members at Closing shall be that number determined by dividing the
portion of the Consideration Amount to be paid in BRI Partnership Units to each
Transferor Member by the value of one BRI Partnership Unit. The parties agree
that, for purposes of this Agreement, the value of each BRI Partnership Unit
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 ten (10) business days prior to the day which
is five (5) business days before the Closing. If the calculation provided for
above results in a fraction of a BRI Partnership Unit to be delivered to a
Transferor Member, the number of BRI Partnership Units to be delivered shall be
rounded up or down to the nearest whole number of BRI Partnership Units.

         Attached hereto as Exhibit I is a schedule (the "Transferor Allocation
Schedule") prepared by the Transferor Members setting forth (i) the name of each
Transferor Member, and (ii) the percentage interest of each Transferor Member,
together with an investor questionnaire in the form attached hereto as Exhibit 5
(the "BRI Questionnaire") for each Transferor Member. In the event that any
Transferor Member 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 Members all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Members
in accordance with the Transferor Allocation Schedule. In addition, if pursuant
to Section 12, the BRI Partnership owes any amounts to the Transferor Members 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 Members in accordance with the election made by the Transferor
Members pursuant to Section 2.02. The BRI Partnership shall have no obligation
or liability with respect to the preparation or accuracy of the Transferor
Allocation Schedule.

                  (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 any Transferor Member 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 Member 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 Members and Berkshire 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 


                                      -11-
<PAGE>


Partnership shall deliver to the Transferor Members a certified copy of the
Registration Rights Agreement.

                  (c) The Transferor Members, 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, 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 this Section, 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 Members in the event of a
decrease or increase in the market value of the common stock of BRI.

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

         2.04 Calculation of Consideration Amount. The Consideration Amount for
the Transferor Membership Interests shall consist of a base consideration amount
("Base Consideration") plus additional consideration installments ("Additional
Consideration Installments").

                  (a) The Base Consideration for the Transferor Membership
Interests shall be Nineteen Million, Eight Hundred Twenty-Eight Thousand, Eight
Hundred Forty-Eight Dollars ($19,828,848).

                  (b) In addition to the Base Consideration, the BRI Partnership
shall pay one or more additional consideration installments (the "Additional
Consideration Installments"), if any, on a quarterly basis with the first
payment, if then due, on the date of Closing and on the first day of each
quarter (defined as a period of three full calendar months, plus, for the first
quarter, any partial calendar month after the date of Closing) thereafter for a
total of 18 full calendar months after the Closing (the "Earn Out Period"). As
of the Closing and as of the first day of each quarter thereafter, Stabilized
NOI shall be determined as provided below, and each Additional Consideration
Installment, if any, will be equal to the Stabilized NOI divided by 8.75% (the
"Cap Rate") and then reduced by the Base Consideration and any prior Additional
Consideration Installments. The maximum Consideration Amount, (i.e. the sum of
the Base Consideration plus all Additional Consideration Installments) shall not
exceed Twenty-Five Million, Five Hundred Eight Thousand, Seven Hundred Nine
Dollars ($25,508,709).

                  (c) Stabilized NOI shall be calculated for purposes of
determining the Additional Consideration Installments as follows: 12 times the
monthly actual income for the Property, (provided that if occupancy rates exceed
95%, then actual income shall be calculated as if the Property had an occupancy
rate of 95%) for the month preceding the payment date less Eight Hundred
Twenty-Eight Thousand, Nine Hundred Eighty-Eight Dollars ($828,988)
(representing the agreed-upon annual Projected Operating Expenses for the
Property), provided that,


                                      -12-
<PAGE>


on the first anniversary of the date of Closing under this Agreement, the
Projected Operating Expenses shall be adjusted by the percentage change in the
CPI-U, U.S. Cities Average for the period from the date of Closing under this
Agreement until the anniversary date.

                                    SECTION 3
                                    ---------

                                   THE CLOSING
                                   -----------

         3.01 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
in Washington, D.C., or such other place as the Transferor Company and the BRI
Partnership shall mutually agree. The "Time of Closing" shall be on that date
specified in Section 3.02 at which 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
Members 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 Members. It is agreed that time is of the essence of this
Agreement.

         3.02 Closing under this Agreement shall occur on the first business day
of the month after the Transferor Members have given to the BRI Partnership 60
days prior notice (the "Substantial Completion Date Notice") of the occurrence
of the last to occur of (a) the substantial completion of construction of the
Property excluding punch-list items not affecting occupancy (provided Transferor
Members shall thereafter complete all punch-list items at no expense to the BRI
Partnership within 30 days after Closing or within such additional time as may
be reasonably required) ("Completion Date") as evidenced by satisfaction of each
of the following conditions (the "Closing Conditions"): (i) final certificates
of occupancy issued by the appropriate governmental authority, and (ii) a
certificate of substantial completion issued by Questar Builders, Inc. or such
affiliate of Transferor Members as Transferor Members may designate to be the
general contractor for construction of the Improvements ("Questar Builders")
certifying that the Improvements have been substantially completed in accordance
with the Plans and Specifications and all Codes, as such may be modified from
time to time by the Transferor Company in accordance with this Agreement, or (b)
the Stabilization Date. If a dispute shall exist as to whether substantial
completion has occurred, the dispute shall be promptly submitted to binding
arbitration by a qualified third party mutually acceptable to the parties or, if
they are unable to agree upon a third party, then by arbitrators appointed
pursuant to the applicable rules of the American Arbitration Association.

         3.03     The Stabilization Date for the Property shall be as follows:



                                      -13-

The first day of that month which first occurs after 90% of the apartment units
in the Property have been leased for a period of 3 months to "Qualified Tenants"
at average rents not less than 90% of the pro-forma rents shown on Schedule
3.03.

         3.04 "Qualified Tenants" are those tenants with annual income equal to
not less than 3 times the annual rent who are in occupancy and have commenced
the payment of rent.

                                    SECTION 4
                                    ---------

                       TRANSFEROR'S PRE-CLOSING DELIVERIES
                       -----------------------------------

         5.29 Public Improvements. To the best knowledge of the Transferor
Company and except as shown on the Plans and Specifications, there are no
written or proposed plans to widen, modify, or realign any street or highway or
any existing or proposed eminent domain proceedings which would affect the
Property in any way that would have a Material Adverse 


                                      -22-

condition which impairs or could impair, the structure of the Property or
renders it in noncompliance with the requirements of this Agreement. No fire or
other casualty shall have occurred on any of the Property, the damage related to

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 Member understands that the BRI
Partnership Units to be issued to each Transferor Member 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 Member.

                  (c) Such Transferor Member acknowledges and agrees that, for
the reasons set forth in Sections 5.34(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 such Transferor Member 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 Member 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 Member 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 matters


                                      -24-
<PAGE>


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, 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
Member 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 Member is an "accredited investor" within
the meaning of Rule 501(a) promulgated under the Act.

                  (e) Such Transferor Member understands that an investment in
the BRI Partnership and BRI involves substantial risks. Such Transferor Member
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 Member 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 may not be offered, sold,

Partnership Units shall be vested in the Transferor Members free and clear of
any lien, claim, charge, pledge encumbrance, limitation, agreement or instrument
whatsoever.

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

         6.08 Private Placement Memorandum. The PPM, as of the date thereof, did
not contain an untrue statement of material fact or omit to state a material

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.

taking and there shall be no adjustment to the Consideration hereunder. If prior

shall occur and be restored by the Transferor Company prior to the Time of
Closing, 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 Transferor Membership
Interests in accordance with the provisions of clause (b) above.

                                    SECTION 8

                                    SECTION 9
                                    ---------

                          OBLIGATIONS PRIOR TO CLOSING
                          ----------------------------

         The Transferor Company covenants that between the date of this
Agreement and the Closing Date:

         9.01 Condition of Units. Up to the Time of Closing, all apartment units
on the Property which become vacant shall, if necessary, be repaired or
otherwise maintained in accordance with the Transferor Company's usual and
customary practice without regard to the Closing contemplated by this Agreement.

         9.02 Service Contracts. The Transferor Company shall not 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.

         9.03 Replacement of Personal Property. No personal property included as
part of the Property shall be removed from the Property unless the same is
replaced with similar items of at least equal quality prior to the Closing Date.

proceedings now or hereafter filed by the Transferor Company to reduce real
property tax assessments, the 


                                      -31-
<PAGE>


Transferor Company 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 Transferor Members 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 Members, in either case after deducting the expenses of collection
thereof, which obligation shall survive the Closing.

         9.05 Property Operating and Maintenance. The Transferor Company shall
lease, manage, maintain and operate the Improvements in the ordinary course of
business. Without limiting the generality of the foregoing, the Transferor
Company shall perform all ordinary maintenance and repair of the mechanical,
electrical and plumbing facilities and equipment within the Improvements so as
to keep such facilities in good operating condition and repair, taking into
account ordinary wear and tear; and to the extent any such facilities or
equipment have heretofore been serviced under a Service Contract, the Transferor
Company shall keep such Service Contracts in full force and effect up to
Closing. For purposes hereof, the parties agree that the Transferor Company has
retained or will retain the BRI Partnership or its affiliate (the "Management
Company") as the manager for the Property pursuant to the Management Agreement
attached hereto as Exhibit 7. The parties agree that the Management Agreement
shall remain in effect until the expiration of the Earn Out Period and, until
then, may not be modified, amended or terminated without the consent of both
parties. Notwithstanding that the BRI Partnership is or will become the owner of
the Management Company, until the expiration of the Earn Out Period, the
Transferor Members shall have control over the activities of the Management
Company and its personnel (including both on-site and managerial) with respect
to the Property, including but not limited to, appointment, hiring, firing,
supervision and compensation (both base and incentive, of personnel, operation,
marketing, promotions and advertising, hours of operation and all other
decisions as to the Property and its leasing and management; provided that such
control shall be exercised in a commercially reasonable manner as compared with
comparable properties in comparable locations. To facilitate this continued
control, BRI Partnership agrees that Patrick Connelly, currently a vice
president of The Questar Management Company, shall remain employed by the
Management Company until the expiration of the Earn Out Period, his principal
place of employment shall remain at the principal regional office of the
Transferor Company and he shall devote such efforts to the Property as the
Transferor Members shall require. Notwithstanding the foregoing, if the

                  (c) 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 paid in cash at Closing by the party owing such amount
to the other party unless the Transferor Members have made an election to
receive BRI Partnership Units, in which event such proration 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) charges or prepayments under transferable Service
Contracts; and

                  (d) 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
Members 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 Members and the BRI Partnership shall cooperate in
the furnishing of all information and documentation necessary to prepare such
calculations. If the Transferor Members have elected to receive BRI Partnership
Units pursuant to Section 2.02, then prior to Closing, the Transferor Members
shall deliver to the 


                                      -43-
<PAGE>


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 Member, and
(ii) the number of BRI Partnership Units to be received by each Transferor
Member. 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 Members
and the Transferor Members hereby release the BRI Partnership from any such
obligation or liability.

         Subject to Section 12.04, all cash (including any escrow deposits)
shall be used by the Transferor Company to pay amounts payable by the Transferor
Company and/or distributed to the Transferor Members prior to Closing, and if
any of such cash applicable to preclosing periods is not removed from the
Transferor Company prior to Closing, the BRI Partnership shall hold such cash as
agent for the Transferor Members and refund such cash to the Transferor Members
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 Company shall distribute the
right to receive such rent to the Transferor Members immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Members in
collecting such rents. 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 Company 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 Members 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 Company 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 Members owe an amount
to the BRI Partnership, the Transferor Members shall have the right to elect to
adjust for such amounts owing by the Transferor Members to the BRI Partnership
in the form of BRI Partnership Units rather than


                                      -44-
<PAGE>


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 Members,
such amount shall be paid in the form of BRI Partnership Units rather than cash,
if the Transferor Members have elected under Section 2.02 to receive BRI
Partnership Units. The Transferor Members shall notify the BRI Partnership at
least seven (7) business days prior to the Closing Date of the manner in which
the Transferor Members shall have elected to settle adjustments under this
Section 12.

                                   SECTION 13
                                   ----------

                               FAILURE TO PERFORM
                               ------------------

         13.01 Defective Title or Condition. If the Transferor Members are
unable to give title or to contribute and transfer the Transferor Membership
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 Membership
Interests or the Property does not conform with the provisions hereof, the BRI
Partnership may elect by written notice given to the Transferor Members 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 Members can deliver to the Transferor Membership
Interests and the Property in its then condition and to deliver in exchange
therefor the Consideration Amount then required to be paid subject to reduction
of the Consideration Amount by the amounts required to remove all Monetary
Liens.

         13.03 Transferor Default. If the Transferor Company or any of the
Transferor Members default in the performance of their obligations under this
Agreement, or if any representation or warranty of the Transferor Company or the
Transferor Members is false or misleading (a "Transferor Default"), the BRI
Partnership shall be entitled to exercise any or all remedies as may be
available at law or in equity on account thereof, including, but not limited to,
an action for specific performance or an action for money damages. By their
execution hereof, Stephen M. Gorn and John B. Colvin ("Guarantors") hereby
guarantee the performance by the Transferor Company of all of its obligations
hereunder and, as part of such guaranty, shall be jointly and severally liable
with the Transferor Company of the payment of all damages to which BRI
Partnership may be entitled.

         13.04 The BRI Partnership's Default. If the BRI Partnership defaults in
performing any of its obligations hereunder, then the Transferor Members shall
be entitled to exercise any or all remedies as may be available at law or in
equity on account thereof, including, but not limited to, an action for specific
performance or an action for money damages.

                                   SECTION 14

                                 BROKERAGE FEES
                                 --------------

         14.01 Brokerage Fees. The Transferor Company 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 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 QPI and the Related
Entities in accordance with the provisions of the Related Agreements. 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 Company have any obligation to pay any
commission to APC.

has entered into with various parties (the "Related Entities") 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 Questar Investment Corporation 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, this Agreement shall terminate automatically simultaneously
with the termination of any such Related Agreement whereupon this Agreement

                            MISCELLANEOUS PROVISIONS
                            ------------------------


         18.01. Assignment. Except as hereinafter provided, this Agreement may
not be assigned prior to Closing by either party hereto. The BRI Partnership
shall have the right to designate an entity affiliated with the BRI Partnership
to accept title to some of the Membership Interests, but the BRI Partnership
shall remain fully liable for the performance of all of its obligations
hereunder. The Transferor Members and the Transferor Company shall have the
right to collaterally assign their interests under this Agreement to a
construction lender providing construction financing for the Improvements (the
"Lender"). This Agreement shall be automatically subject and subordinate to the
mortgage, deed of trust and all other loan documents now or hereafter entered
into evidencing the loan and security of the Lender. If the Transferor Members
and Transferor Company so assign this Agreement, then the the BRI Partnership
agrees to enter into an agreement with the Lender (the "Tri Party Agreement")
providing that: (a) the BRI Partnership agrees to provide the Lender with
reasonable notice and opportunity to cure any default by the Transferor Members
or the Transferor Company hereunder; (b) the BRI Partnership agrees not to
modify or amend this Agreement without the prior written consent of Lender, (c)
the BRI Partnership, at the written request of Lender upon a default under the
loan, will pay the Base Consideration or such lesser amount as is required to
satisfy the loan directly to Lender provided that all of the conditions to
Closing provided herein have been satisfied; (d) the Lender agrees to recognize
the rights of BRI Partnership under this Agreement; (e) the BRI Partnership will
permit Lender to perform any obligations of the Transferor Company and
Transferor Members hereunder and will agree to recognize Lender as the
Transferor Company and the Transferor Members hereunder should Lender succeed to

                                      -2-
<PAGE>

                                    SECTION 1
                                    ---------

             CONTRIBUTION OF MEMBERSHIP INTERESTS AND DUE DILIGENCE
             ------------------------------------------------------

         1.01 The Transferor Members shall contribute to the BRI Partnership,
and the BRI Partnership shall accept from the Transferor Members, in exchange
for either cash or BRI Partnership Units, and upon the terms and conditions set
forth in this Agreement, all of the Transferor Members' membership interests in
the Transferor Company (the "Transferor Membership Interests"). The percentage
of interest that each of the Transferor Members owns in the Transferor Company
is listed on Exhibit I. At the Closing (as defined in Section 3.01), the
Transferor Members shall, respectively, contribute, assign, transfer and deliver
the Transferor Membership Interests to the BRI Partnership, or its designees as
provided in Section 18.01 hereof, by an Assignment and Assumption of Membership
Interest in the form of Exhibit III attached hereto (the "Transferor
Assignment"). Immediately thereafter, the Transferor Members and the BRI
Partnership, or its designees, shall execute and deliver an Amended and Restated
Operating Agreement in the form of Exhibit IV attached hereto (the "Amended
Transferor Operating Agreement") and an Amended and Restated Articles of
Organization in the form of Exhibit V attached hereto (the "Amended Transferor
Company Articles") pursuant to which the BRI Partnership, or its designees,
shall be admitted and the Transferor Members shall withdraw, as the members of
the Transferor Company and be released of all liability thereunder, and the
terms of the Transferor Company shall be amended in accordance with the Amended
Transferor Operating Agreement.

         1.02 Property Title. On or before September 22, 1997, the Transferor
Members shall deliver to the BRI Partnership a copy of the Transferor Company's
existing title insurance commitment or policy (the "Commitment") 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").

         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 Company on or before October 1, 1997 if any such
exceptions are unacceptable. If the BRI Partnership fails to so notify the
Transferor Company 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". Any easements or other agreements reasonably required
for the development and construction of the Property and the Improvements now or
hereafter entered into by the Transferor Company; including an agreement for the
shared use and the sharing of the operating expenses of the common recreational
facilities located on the Property and an easement declaration creating
cross-easements for the roads, storm water management ponds and the sewage
pumping station on the Property, all of which are consistent with the Plans and
Specifications and, in the reasonable discretion of the BRI Partnership, do not
materially interfere with the intended use of


                                      -3-
<PAGE>

the Property nor materially affect the value of the Property, shall also
constitute Permitted Exceptions.

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at the BRI Partnership's sole cost, shall obtain a new
commitment (the "Updated Commitment") for Title Insurance for an ALTA Form B
Owner's Title Insurance Policy from Lawyer's Title Insurance Corporation (the
"Title Insurer"). The Updated Commitment shall insure fee simple title to the
Property in the sole name of the Transferor Company and shall be in the amount
of $15,419,635. The Updated 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 and are available under the law of the state in
which the Property is located. If any new exceptions to title appear in the
Updated Commitment that do not constitute Permitted Exceptions and that are
unacceptable to the BRI Partnership, in its reasonable discretion, the BRI
Partnership may notify the Transferor Company within thirty (30) days after the
Completion Date Notice.

         If any exceptions in the Commitment or the Updated Commitment are
unacceptable to the BRI Partnership in accordance with the foregoing provisions,
and the BRI Partnership timely notifies the Transferor Company in writing of
such fact as above provided, the Transferor Company shall have thirty (30) days
from the date the Transferor Company receives notice of such unacceptable
exceptions, at the option of the Transferor Company, to remove or cure such
exceptions, provided further, the Transferor Company 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 liens for real estate taxes and current water and sewer charges for the
fiscal year in which Closing occurs, 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 Company at Closing. The
Transferor Company shall be deemed to have refused to cure any unacceptable
exceptions unless the Transferor Company, within ten (10) days after receipt of
notice from the BRI Partnership, shall notify the BRI Partnership in writing
that the Transferor Company will attempt to cure such unacceptable exceptions.
If the Transferor Company 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 Company 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 Company or
(ii) waive such exceptions and accept title subject thereto, in which event
there shall be a reduction in the Purchase Price (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 22, 1997, the Transferor Company
shall provide to the BRI Partnership a copy of its existing survey (the
"Survey") of the Land and any Improvements.

         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 Company on or before
October 1, 1997 if any such survey matters are unacceptable. If the BRI
Partnership fails to so notify the Transferor Company 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."

         Within thirty (30) days after the Substantial Completion Date Notice,
the BRI Partnership, at its sole cost and expense, shall obtain an updated
survey (the "Updated Survey") by a registered land surveyor (the "Surveyor")
acceptable to the BRI Partnership, which Updated 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
Updated Survey and the recorded legal description. The BRI Partnership shall
provide a copy of the Updated Survey to the Transferor Company promptly after
its receipt thereof. If any new matters appear on the Updated Survey that do not
constitute Permitted Exceptions, do not simply reflect the construction of the
Improvements in locations that do not encroach upon property lines, setback
lines or easements, and are unacceptable to the BRI Partnership in its
reasonable discretion, the BRI Partnership may notify the Transferor Company
within forty (40) days after the Substantial Completion Date Notice.

         If any survey matters are unacceptable to the BRI Partnership in
accordance with the foregoing provisions, and the BRI Partnership timely
notifies the Transferor Company in writing of such fact as above provided, the
Transferor Company shall have thirty (30) days from the date the Transferor
Company receives notice of such unacceptable survey matters, at the option of
the Transferor Company, to cure such unacceptable survey matters. The Transferor
Company shall be deemed to have refused to cure any unacceptable survey matters
unless the Transferor Company, within ten (10) days


                                      -5-
<PAGE>

after receipt of notice from the BRI Partnership, shall notify the BRI
Partnership in writing that the Transferor Company will attempt to cure such
unacceptable survey matters. If the Transferor Company 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 Company 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 Company 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     Construction and Inspection.

                  (a) Plans and Specifications. Prior to the date of this
Agreement, Transferor Company has delivered to BRI Partnership true, correct and
complete copies of the Preliminary Plans and Specifications for the construction
of the Improvements as set forth on Schedule C attached hereto. After the date
hereof, the Transferor Company, at its sole cost and expense, shall prepare
complete construction plans and specifications for the Improvements and submit
them to the BRI Partnership for approval, such approval not to be unreasonably
withheld. The Transferor Company shall prepare the construction plans and
specifications in good faith and so as to be in accordance with the Preliminary
Plans and Specifications, and the BRI Partnership shall act in good faith when
approving the construction plans and specifications and shall not disapprove any
aspects of the construction plans and specifications that are in accordance with
the Preliminary Plans and Specifications. BRI Partnership shall notify the
Transferor Company in writing of its approval or disapproval of the construction
plans and specifications within 30 days following receipt. If BRI Partnership
does not approve the construction plans and specifications, then the parties
shall work in good faith to resolve any differences, but, if within 30 days
after submittal, the parties have not agreed upon the construction plans and
specifications, then either party, by written notice to the other, may terminate
this Agreement, and, upon the giving of such notice, the Deposit shall be
returned to the BRI Partnership and neither party shall have any further rights
or obligations hereunder. Once agreed upon, the construction plans and
specifications shall be deemed the "Plans and Specifications" for all purposes
of this Agreement. BRI Partnership and the Transferor Company, as part of, or
prior to, the approval of the construction plans and specifications may mutually
agree upon changes to the quality or level of Improvements to that shown in the
Preliminary Plans and Specifications and, in such event, the parties shall also
agree upon an appropriate upward or downward adjustment in the Consideration
Amount.

                  (b) Transferor Company to Construct Improvements. Transferor
Company shall, at Transferor Company's expense, obtain all permits and construct
the Improvements on the Land in accordance with the Plans and Specifications, as
the same may be modified by change order in accordance with this Agreement. All
work shall be done in a good and workmanlike manner using new, good quality
materials, free of all defects and in compliance with all Codes (as defined in
Section 5.21), permits, approvals, title restrictions and insurance
requirements. Transferor Company shall obtain builder's risk insurance on the
Improvements in the amount of the construction cost of those buildings from time
to time for which construction has commenced. Transferor Company shall deliver a
certificate of such insurance to BRI 


                                      -6-
<PAGE>

Partnership. Transferor Company shall maintain such insurance in force and
effect through the course of construction and until Closing hereunder.

                  (c) Inspection of Construction; Correction of Defects. BRI
Partnership and its engineers, consultants and agents may inspect the
construction of the Improvements from time to time during the course of
construction upon reasonable notice to the Transferor Company. After receipt
from the Transferor Company of written notice that the requirements of Section
3.02(a)(i) and (ii) have been satisfied (the "Inspection Notice"), BRI
Partnership and its engineers, consultants and agents shall inspect the
construction of the Improvements upon reasonable notice to Transferor Company to
determine whether such construction is completed in accordance with the Plans
and Specifications. Within 30 days after the Inspection Notice, BRI Partnership
will give written notice to Transferor Company of any nonconformities with the
Plans and Specifications and defects or deficiencies in construction identified
by BRI Partnership. Unless Transferor Company disagrees with BRI Partnership,
which disagreement shall be expressed by giving written notice to the BRI
Partnership stating the basis for said disagreements, within 10 days after such
BRI Partnership notice, Transferor Company, at Transferor Company's expense,
shall commence to correct, repair or replace any such nonconformities, defects
or deficiencies and shall diligently continue thereafter until completion of
such corrections, repairs or replacements, and, if such deficiencies are of such
a magnitude that Closing would not otherwise be required to occur under Section
3.02 and Section 5.30, the Closing Date shall be extended until the deficiencies
are corrected. Any dispute shall be resolved by arbitration in accordance with
Section 3.02.

                  (d) Change Orders. The Transferor Company shall not change or
modify the Plans and Specifications without prior written approval of the BRI
Partnership, such approval not to be unreasonably withheld, provided, however
that the following changes shall not require BRI Partnership's approval: (i)
changes required by the construction lender or governmental authorities, and
(ii) changes in the design of the Improvements resulting in a decrease or
increase in construction cost by less than $100,000 for an individual change and
less than $250,000 in the aggregate. The Transferor Company shall give written
notice to BRI Partnership of all proposed changes to the Plans and
Specifications by sending a complete copy of the change, together with copies of
any plans or drawings related thereto. BRI Partnership shall give its written
approval or disapproval within five (5) business days thereafter. If BRI
Partnership disapproves any such change, the Transferor Company shall not
implement same.

                  (e) Completion. The Transferor Company shall diligently
attempt to complete construction of the Improvements in accordance with the
Plans and Specifications, as modified in accordance with this Agreement, and in
compliance with all Codes (as defined in Section 5.21 hereof) by December 31,
2003 (the "Scheduled Completion Date"). For purposes of this Agreement, the
"Completion Date" shall be the date upon which all of the Closing Conditions
shall have been satisfied as set forth in Section 3.02.


                                      -7-
<PAGE>

                  (f) Force Majeure. In the event that the Transferor Company is
delayed in the commencement or completion of construction of the Improvements by
acts of God, war, civil commotion, fire, flood or other casualty, labor
difficulties, strikes, shortages of labor, materials or equipment, undue delay
in action by governmental authorities, governmental or utility company refusal
to issue building, construction, utility, occupancy or other permits or
approvals, water, sewer or other utility moratorium (including enforcement of
the requirements of any adequate public facilities ordinance) or other causes
beyond the Transferor Company's reasonable control (a "Force Majeure Event"),
the Scheduled Completion Date shall be extended for the period of delay, not to
exceed 12 months. If a Force Majeure Event continues in effect for a period in
excess of 12 months, during which construction is delayed, then the Transferor
Company may, by notice to BRI Partnership terminate this Agreement, in which
event the Deposit shall be returned to the BRI Partnership and neither party
shall have any further liability to the other hereunder. In addition,
simultaneously with closing under the Related Agreements, the Transferor Company
shall execute and deliver to BRI Partnership the Right of First Offer Agreement
attached hereto as Exhibit IX, which Right of First Offer Agreement shall
contain, among other provisions a Right of First Refusal which provides: (a)
that the BRI Partnership shall have a right of first refusal to purchase the
Property following the termination of this Agreement pursuant to this Section
1.04(f), (b) BRI Partnership shall have a period of 15 business days, following
receipt of a bona fide third party letter of intent to purchase the Property, to
agree to purchase the Property on the same terms and conditions as set forth in
the letter of intent, and (c) such Right of First Offer Agreement shall be
subordinate to any mortgage or deed of trust securing construction financing on
the Property.

         1.05     Environmental Due Diligence Inspection.

                  (a) On or before September 22, 1997, the Transferor Company
shall deliver to the BRI Partnership a copy of its environmental report for the
Property (the "Initial Environmental Report"). Should the BRI Partnership
decide, in its sole judgment, during the period up to and including October 1,
1997 (the "Due Diligence Period") that the Initial Environmental Report is
unsatisfactory, the BRI Partnership shall have the right to terminate this
Agreement by giving written notice of its election to do so 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. 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 the period expiring
30 days after the Substantial Completion Date Notice during regular business
hours and on reasonable prior notice to the Transferor Company, inspect the
Property to determine the presence of any Hazardous Materials (as defined in
Section 5.20) and the compliance of the Property with Environmental Laws (as
defined in Section 5.20) 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


                                      -8-
<PAGE>

Transferor Company 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 Company in this Agreement. Should the BRI
Partnership decide, in its reasonable judgment, that there exists an
environmental risk with respect to the Property (excluding such items as
asbestos roof shingles, asbestos floor tile and mastic, PCBs in electric light
ballasts, HCFCs or CFSs in HVAC units, the presence of usual and customary
cleaning and maintenance supplies and similar items that are typically handled
through the adoption of appropriate operations policies), during the period
expiring 30 days after the Substantial Completion Date Notice 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 Company on or before 30 days after the Substantial
Completion Date, and upon the giving of such notice this Agreement shall be of
no further force or effect. Notwithstanding the foregoing, the BRI Partnership
may not disapprove or object to any matter disclosed by the Environmental
Inspection that was disclosed in the Initial Environmental Report. If the BRI
Partnership shall fail to exercise such termination right within any such
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 1.05.
The BRI Partnership shall pay when due all fees and expenses incurred in the
performance of the Environmental Inspection performed at its request.

                  (b) From and after the date of this Agreement, the Transferor
Company shall permit the BRI Partnership's authorized agents and representatives
(including its accountants) to examine (including, without limitation, the right
to audit) the Transferor Company'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 Company's financial records relating to the Property
have been audited, the Transferor Company agrees to deliver any reports relating
to such audits to the BRI Partnership. The Transferor Company shall provide the
BRI Partnership with such information as the Transferor Company 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 Company, all taxes and utility payments made 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 1.05(b) 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 Company if the Closing does not occur.

                  (c) The BRI Partnership shall indemnify the Transferor Members
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 


                                      -9-
<PAGE>


Property by them, or any of them, together with all expenses incurred by the
Transferor Members 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 Members 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 1.05(c) shall survive
the Closing or any termination of this Agreement; provided, however, that no
claim by the Transferor Members under this Section 1.05(c) 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 Members 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 Members hereunder.

         1.06 Tax Treatment. The parties intend that, to the extent the
Transferor Members receive BRI Partnership Units as the consideration for the
contribution of the Transferor Membership Interests by the Transferor Members to
the BRI Partnership in accordance with Section 1.01 of this Agreement, such
contribution shall 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 Members agree to
report such transaction for federal and applicable state income tax purposes
consistently with the intent set forth in this Section 1.06.

                                    SECTION 2
                                    ---------

                                  CONSIDERATION
                                  -------------

         The consideration for the Membership Interests (the "Consideration
Amount"), subject to the adjustments contained in Section 12 of this Agreement,
shall be determined pursuant to the provisions of Section 2.04, and shall be
paid by the the BRI Partnership to the Transferor Members in the following
manner:

         2.01     Deposit.

                  (a) Simultaneously with the execution of this Agreement, the
the BRI Partnership shall deliver to Lawyers Title Insurance Corporation (the
"Escrow Agent") the sum of ONE DOLLAR ($1.00) (the "Initial Deposit") by check
(subject to collection) as a Deposit to be held in an interest-bearing escrow
account on account of the Consideration Amount. Said sum, together with any
interest earned thereon, is hereinafter called the "Deposit."


                                      -10-
<PAGE>


                  (b) At the Closing, the Deposit shall be returned by the
Escrow Agent to BRI Partnership.

         2.02 Balance. At the Closing, the BRI Partnership shall deliver to the
Transferor Members the Base Consideration, plus, if then due, any Additional
Consideration Installments, subject to the adjustments described in Section 12
of this Agreement by federal wired funds. Prior to any delivery to the
Transferor Members of the Base Consideration, there shall be deducted from the
Base Consideration an amount equal to the sum required to pay off the
Construction Loan in full and to remove all other Monetary Liens and
simultaneously with the Closing, the BRI Partnership shall pay off the
Construction Loan. At the Transferor members' option, to be exercised
irrevocably by written notice to the BRI Partnership given at least 15 days
prior to the satisfaction of the Closing Conditions, all or a portion of the
Consideration Amount shall be delivered to the Transferor Members in the form of
BRI Partnership Units in the BRI Partnership. If the Transferor Members exercise
such option, then the number of BRI Partnership Units, the rights and
limitations upon such units and the method by which the units are delivered to
the Transferor Members at Closing shall be as provided in Sections 2.02 (a), (b)
and (c) below. If the Transferor Members do not exercise the foregoing option in
a timely manner, all consideration payable under this Agreement shall be paid in
cash by federal wired funds and the following Sections of this Agreement shall
be, without further action by any party, null and void and without any further
force or effect upon the parties: 1.06, 2.02(a) through (c), 5.34, 6.03, 6.05,
6.06, 6.08, 6.09, 6.10, 6.12 through 6.16, 10.01(e), 10.04, 11.01(a) (ii), (iii)
and (iv) and 11.01(d) (last sentence only), 11.03 and 12.04.

                  (a) The number of BRI Partnership Units to be issued to the
Transferor Members at Closing shall be that number determined by dividing the
portion of the Consideration Amount to be paid in BRI Partnership Units to each
Transferor Member by the value of one BRI Partnership Unit. The parties agree
that, for purposes of this Agreement, the value of each BRI Partnership Unit
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 ten (10) business days prior to the day which
is five (5) business days before the Closing. If the calculation provided for
above results in a fraction of a BRI Partnership Unit to be delivered to a
Transferor Member, the number of BRI Partnership Units to be delivered shall be
rounded up or down to the nearest whole number of BRI Partnership Units.

         Attached hereto as Exhibit I is a schedule (the "Transferor Allocation
Schedule") prepared by the Transferor Members setting forth (i) the name of each
Transferor Member, and (ii) the percentage interest of each Transferor Member,
together with an investor questionnaire in the form attached hereto as Exhibit 5
(the "BRI Questionnaire") for each Transferor Member. In the event that any
Transferor Member 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 Members all of the BRI Partnership Confirmations
evidencing the issuance of the BRI Partnership Units to the Transferor Members
in accordance with the Transferor Allocation


                                      -11-
<PAGE>

Schedule. In addition, if pursuant to Section 12, the BRI Partnership owes any
amounts to the Transferor Members 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 Members in accordance with the election
made by the Transferor Members pursuant to Section 2.02. The BRI Partnership
shall have no obligation or liability with respect to the preparation or
accuracy of the Transferor Allocation Schedule.

                  (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 any Transferor Member 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 Member 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 Members and Berkshire 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 Members a certified copy of the
Registration Rights Agreement.

                  (c) The Transferor Members, 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, 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 this Section, 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 Members in the event of a
decrease or increase in the market value of the common stock of BRI.

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

         2.04 Calculation of Consideration Amount. The Consideration Amount for
the Transferor Membership Interests shall consist of a base consideration amount
("Base Consideration") plus additional consideration installments ("Additional
Consideration Installments").

                  (a) The Base Consideration for the Transferor Membership
Interests shall be Fifteen Million, Four Hundred Nineteen Thousand, Six Hundred
Thirty-Five Dollars ($15,419,635).



                                      -12-
<PAGE>


                  (b) In addition to the Base Consideration, the BRI Partnership
shall pay one or more additional consideration installments (the "Additional
Consideration Installments"), if any, on a quarterly basis with the first
payment, if then due, on the date of Closing and on the first day of each
quarter (defined as a period of three full calendar months, plus, for the first
quarter, any partial calendar month after the date of Closing) thereafter for a
total of 18 full calendar months after the Closing (the "Earn Out Period). As
of the Closing and as of the first day of each quarter thereafter, Stabilized
NOI shall be determined as provided below, and each Additional Consideration
Installment, if any, will be equal to the Stabilized NOI divided by 10% (the
"Cap Rate") and then reduced by the Base Consideration and any prior Additional
Consideration Installments.

                  (c) Stabilized NOI shall be calculated for purposes of
determining the Additional Consideration Installments as follows: 12 times the
monthly actual income for the Property, (provided that if occupancy rates exceed
95%, then actual income shall be calculated as if the Property had an occupancy
rate of 95%) for the month preceding the payment date less Three Hundred
Ninety-Six Thousand, One Hundred Dollars ($396,100) (representing the
agreed-upon annual Projected Operating Expenses for the Property), provided
that, on the first anniversary of the date of Closing under this Agreement, the
Projected Operating Expenses shall be adjusted by the percentage change in the
CPI-U, U.S. Cities Average for the period from the date of Closing under this
Agreement until the anniversary date.

                                   THE CLOSING
                                   -----------

         3.01 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
in Washington, D.C., or such other place as the Transferor Company and the BRI
Partnership shall mutually agree. The "Time of Closing" shall be on that date
specified in Section 3.02 at which 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
Members 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 Members. It is agreed that time is of the essence of this
Agreement.

         3.02 Closing under this Agreement shall occur on the first business day
of the month after the Transferor Members have given to the BRI Partnership 60
days prior notice (the "Substantial Completion Date Notice") of the occurrence
of the last to occur of (a) the substantial completion of construction of the
Property excluding punch-list items not affecting occupancy (provided Transferor
Members shall thereafter complete all punch-list items at no expense to the BRI
Partnership within 30 days after Closing or within such additional time as may
be 


                                      -13-

reasonably required) ("Completion Date") as evidenced by satisfaction of each of
the following conditions (the "Closing Conditions"): (i) final certificates of

time to time by the Transferor Company in accordance with this Agreement, or (b)
the Stabilization Date. If a dispute shall exist as to whether substantial
completion has occurred, the dispute shall be promptly submitted to binding
arbitration by a qualified third party mutually acceptable to the parties or, if
they are unable to agree upon a third party, then by arbitrators appointed
pursuant to the applicable rules of the American Arbitration Association.

         3.03     The Stabilization Date for the Property shall be as follows:

The first day of that month which first occurs after 90% of the apartment units
in the Property have been leased for a period of 3 months to Qualified Tenants.

         3.04 "Qualified Tenants" are those tenants with annual income equal to
not less than 3 times the annual rent who are in occupancy and have commenced
the payment of rent.

                                    ---------

Transferor Company.

encumbrances and all attorneys' fees and other costs and expenses incurred by
reason thereof.

         5.27 Essential Facilities. Except as set forth in Schedule 5.27, the
Property is an independent unit which does not now rely on any facilities (other

Company and except as shown on the Plans and Specifications, there are no
written or proposed plans to widen, modify, or realign any street or highway or
any existing or proposed eminent domain proceedings which would affect the
Property in any way that would have a Material Adverse Effect. To the best
knowledge of the Transferor Company, there are no presently planned public
improvements which would result in the creation of a special improvement or
similar lien upon the Property.

         5.30 Condition of Improvements. The Property, including, without
limitation, curbs, sidewalks, air conditioning, roofs, mechanical, electrical,
HVAC systems and equipment, plumbing, drainage and heating systems and other

substantially in accordance with (i) the Plans and Specifications, (ii) all
applicable Codes, permits, approvals, title encumbrances and insurance
requirements and (iii) accepted standards of good materials and workmanship. As

condition which impairs or could impair, the structure of the Property or
renders it in noncompliance with the requirements of this Agreement. No fire or
other casualty shall have occurred on any of the Property, the damage related to
which has not been repaired or restored to the condition the Property was in

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

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

Agreement and has not relied upon the BRI Partnership, 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 Member 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 Member is an "accredited investor" within
the meaning of Rule 501(a) promulgated under the Act.

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

Agreement, as amended to date, and has had the opportunity to review all

<PAGE>

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 Members 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

any material part of the Property is subject to any eminent domain notice or

amenities), then the BRI Partnership shall have the option, exercisable by
written notice given to the Transferor Members at or prior to the Time of

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

Closing, 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 Transferor Membership
Interests in accordance with the provisions of clause (b) above.

                                    SECTION 8

<PAGE>


         9.01 Condition of Units. Up to the Time of Closing, all apartment units
on the Property which become vacant shall, if necessary, be repaired or
otherwise maintained in accordance with the Transferor Company's usual and
customary practice without regard to the Closing contemplated by this Agreement.

         9.02 Service Contracts. The Transferor Company shall not 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.

         9.03 Replacement of Personal Property. No personal property included as
part of the Property shall be removed from the Property unless the same is
replaced with similar items of at least equal quality prior to the Closing Date.

         9.04 Tax Procedure. Except as to real property tax assessment appeal
proceedings now or hereafter filed by the Transferor Company to reduce real
property tax assessments, the Transferor Company 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 Transferor Members 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 Members, in either case after deducting the
expenses of collection thereof, which obligation shall survive the Closing.

         9.05 Property Operating and Maintenance. The Transferor Company shall
lease, manage, maintain and operate the Improvements in the ordinary course of
business. Without limiting the generality of the foregoing, the Transferor
Company shall perform all ordinary maintenance and repair of the mechanical,
electrical and plumbing facilities and equipment within the Improvements so as
to keep such facilities in good operating condition and repair, taking into
account ordinary wear and tear; and to the extent any such facilities or
equipment have heretofore been serviced under a Service Contract, the Transferor
Company shall keep such Service Contracts in full force and effect up to
Closing. For purposes hereof, the parties agree that the Transferor Company has
retained or will retain the BRI Partnership or its affiliate (the "Management
Company") as the manager for the Property pursuant to the Management Agreement
attached hereto as Exhibit 7. The parties agree that the Management Agreement
shall remain in effect until the expiration of the Earn Out Period and, until
then, may not be modified, amended or terminated without the consent of both
parties. Notwithstanding that the BRI Partnership is or will become the owner of
the Management Company, until the expiration of the Earn Out Period, the
Transferor Members shall have control over the activities of the Management
Company and its personnel (including both on-site and managerial) with respect
to 


                                      -32-
<PAGE>


the Property, including but not limited to, appointment, hiring, firing,
supervision and compensation (both base and incentive, of personnel, operation,
marketing, promotions and advertising, hours of operation and all other
decisions as to the Property and its leasing and management; provided that such
control shall be exercised in a commercially reasonable manner as compared with
comparable properties in comparable locations. To facilitate this continued
control, BRI Partnership agrees that Patrick Connelly, currently a vice
president of The Questar Management Company, shall remain employed by the
Management Company until the expiration of the Earn Out Period, his principal
place of employment shall remain at the principal regional office of the
Transferor Company and he shall devote such efforts to the Property as the
Transferor Members shall require. Notwithstanding the foregoing, if the
employment agreement of Stephen M. Gorn is terminated by BRI Partnership, then
the Transferor Members at their option, may elect (a) to terminate the
management agreement with BRI Partnership and either manage, lease and operate
the Property on their own behalf or retain such other persons or entities to do
so as they deem appropriate on substantially the same terms (including, but not
limited to, the same management fee) as are provided in the management agreement
with BRI Partnership, and (b) to attempt to recruit Patrick Connelly as their
full-time employee.

         9.06 Lease Amendments. The Transferor Company shall not amend, alter,
modify or vary the terms and provisions of any of Leases except in the ordinary
course of business, without first obtaining the written consent of the BRI
Partnership, which consent shall not be unreasonably withheld or delayed.

         9.07 New Leases. From and after the date hereof, the Transferor Company
shall not make, execute nor permit any new Lease for any apartment in the
Property without first obtaining the written consent of the BRI Partnership,
unless such Lease (i) is on the form lease provided to the BRI Partnership, and
(ii) is with a Qualified Tenant.

         9.08 Preservation of Partnership Business. On and after the date
hereof, except with the prior written consent of the BRI Partnership or as
otherwise provided in this Agreement, the Transferor Company shall not cause,
acquiesce in, or agree to:

                  (a) a material amendment, modification, termination or
cancellation of the Transferor Operating Agreement without the prior written
consent of the BRI Partnership, which shall not be unreasonably withheld or
delayed, provided that such amendment modification, termination or cancellation
does not adversely affect the BRI Partnership's rights under this Agreement;

receive BRI Partnership Units, in which event such proration 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) charges or prepayments under transferable Service
Contracts; and

                  (d) 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


                                      -43-
<PAGE>


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
Members 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 Members and the BRI Partnership shall cooperate in
the furnishing of all information and documentation necessary to prepare such
calculations. If the Transferor Members have elected to receive BRI Partnership
Units pursuant to Section 2.02, then prior to Closing, the Transferor Members
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 Member, and (ii) the number of BRI Partnership Units to be received
by each Transferor Member. 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 Members and the Transferor Members hereby release
the BRI Partnership from any such obligation or liability.

         Subject to Section 12.04, all cash (including any escrow deposits)
shall be used by the Transferor Company to pay amounts payable by the Transferor
Company and/or distributed to the Transferor Members prior to Closing, and if
any of such cash applicable to preclosing periods is not removed from the
Transferor Company prior to Closing, the BRI Partnership shall hold such cash as
agent for the Transferor Members and refund such cash to the Transferor Members
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 Company shall distribute the
right to receive such rent to the Transferor Members immediately prior to
Closing. The BRI Partnership shall act as agent for the Transferor Members in
collecting such rents. 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 Company 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 Members or the BRI Partnership after the
Closing are payable to the other party by reason of this allocation or


                                      -44-
<PAGE>


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 Company 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 Members owe an amount
to the BRI Partnership, the Transferor Members shall have the right to elect to
adjust for such amounts owing by the Transferor Members 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 Members, such amount shall be paid
in the form of BRI Partnership Units rather than cash, if the Transferor Members
have elected under Section 2.02 to receive BRI Partnership Units. The Transferor
Members shall notify the BRI Partnership at least seven (7) business days prior
to the Closing Date of the manner in which the Transferor Members shall have
elected to settle adjustments under this Section 12.

                                   SECTION 13
                                   ----------

                               FAILURE TO PERFORM
                               ------------------

         13.01 Defective Title or Condition. If the Transferor Members are
unable to give title or to contribute and transfer the Transferor Membership
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 Membership
Interests or the Property does not conform with the provisions hereof, the BRI
Partnership may elect by written notice given to the Transferor Members 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 Members can deliver to the Transferor Membership
Interests and the Property in its then condition and to deliver in exchange
therefor the Consideration Amount then required to be paid subject to reduction
of the Consideration Amount by the amounts required to remove all Monetary
Liens.

         13.03 Transferor Default. If the Transferor Company or any of the
Transferor Members default in the performance of their obligations under this
Agreement, or if any representation or warranty of the Transferor Company or the
Transferor Members is false or misleading (a


                                      -45-
<PAGE>


"Transferor Default"), the BRI Partnership shall be entitled to exercise any or
all remedies as may be available at law or in equity on account thereof,
including, but not limited to, an action for specific performance or an action
for money damages. By their execution hereof, Stephen M. Gorn and John B. Colvin
("Guarantors") hereby guarantee the performance by the Transferor Company of all
of its obligations hereunder and, as part of such guaranty, shall be jointly and
severally liable with the Transferor Company of the payment of all damages to
which BRI Partnership may be entitled.

         13.04 The BRI Partnership's Default. If the BRI Partnership defaults in
performing any of its obligations hereunder, then the Transferor Members shall
be entitled to exercise any or all remedies as may be available at law or in
equity on account thereof, including, but not limited to, an action for specific
performance or an action for money damages.

                                   SECTION 14
                                   ----------

                                 BROKERAGE FEES
                                 --------------

         14.01 Brokerage Fees. The Transferor Company 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 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 QPI and the Related
Entities in accordance with the provisions of the Related Agreements. 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 Company have any obligation to pay any
commission to APC.

                                   SECTION 15

shall survive until twelve (12) months after the Closing Date and thereafter

provided herein to survive the Closing.

                                   SECTION 17
                                   ----------

                  (d) Title to Membership Interests. The Transferor Membership

construction of the Improvements in accordance with the Plans and
Specifications, as modified in accordance with this Agreement, and in compliance
with all Codes all to the extent required under Sections 3.02 and 5.30, and, if
such completion shall have occurred prior to the occurrence of the Stabilization
Date, then, in addition to the foregoing, as of the Closing, the Improvements
shall remain completed to the extent required under Sections 3.02 and 5.30 and
shall be in substantially the same condition (subject to the provisions of
Section 7.02 and to any damage to the Improvements caused by tenants) as they
were in at the time of the BRI Partnerships' inspection pursuant to Section
1.04(c) with all identified construction deficiencies corrected.

         In the event that any condition set forth in Section 17.01(a) through
Section 17.07(e) hereinabove is neither satisfied nor waived by the BRI
Partnership in writing, on or before the Closing Date, the BRI Partnership shall
be entitled to terminate this Agreement by written notice given to the

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

         17.02 Transferor Conditions. Without limiting any other conditions to
Closing of the Transferor Members contained herein, the obligation of the

approvals necessary to be obtained before Closing shall have been obtained.

                  (d) BRI Partnership Units. The BRI Partnership Units shall, as

whatsoever.

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

has entered into with various parties (the "Related Entities") 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 Questar Investment Corporation 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, this Agreement shall terminate automatically simultaneously
with the termination of any such Related Agreement 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
provisions of this Section 17.03 shall be of no further force or effect once
closing occurs under any one or more of the Related Agreements.


                                   SECTION 18
                                   ----------

                            MISCELLANEOUS PROVISIONS
                            ------------------------

         18.01. Assignment. Except as hereinafter provided, this Agreement may
not be assigned prior to Closing by either party hereto. The BRI Partnership
shall have the right to designate an entity affiliated with the BRI Partnership
to accept title to some of the Membership Interests, but the BRI Partnership
shall remain fully liable for the performance of all of its obligations
hereunder. The Transferor Members and the Transferor Company shall have the
right to collaterally assign their interests under this Agreement to a
construction lender providing construction financing for the Improvements (the
"Lender"). This Agreement shall be automatically subject and subordinate to the
mortgage, deed of trust and all other loan documents 


                                      -50-
<PAGE>


now or hereafter entered into evidencing the loan and security of the Lender. If
the Transferor Members and Transferor Company so assign this Agreement, then the
the BRI Partnership agrees to enter into an agreement with the Lender (the "Tri
Party Agreement") providing that: (a) the BRI Partnership agrees to provide the
Lender with reasonable notice and opportunity to cure any default by the
Transferor Members or the Transferor Company hereunder; (b) the BRI Partnership
agrees not to modify or amend this Agreement without the prior written consent
of Lender, (c) the BRI Partnership, at the written request of Lender upon a
default under the loan, will pay the Base Consideration or such lesser amount as
is required to satisfy the loan directly to Lender provided that all of the
conditions to Closing provided herein have been satisfied; (d) the Lender agrees
to recognize the rights of BRI Partnership under this Agreement; (e) the BRI
Partnership will permit Lender to perform any obligations of the Transferor
Company and Transferor Members hereunder and will agree to recognize Lender as
the Transferor Company and the Transferor Members hereunder should Lender
succeed to the interest of the Transferor Company and Transferor Members,
provided, however, that, in such event, Lender's liability under this Agreement
shall be limited to its interest in the Transferor Company and the Property; and
further provided that (f) the BRI Partnership will have no liability for payment
of the Lender's loan or the performance of any obligations under any of the loan
documents other than the Tri-Party Agreement; and (g) the amount to be paid to
Lender shall be payable in cash only and not in BRI Partnership Units and shall
be limited to the amount provided in clause (c). The parties acknowledge and
agree that the Transferor Company is currently the owner of land in addition to
the Land (the "Additional Avalon Land") which is the subject of a separate
Development Contribution Agreement (the "Other Avalon Agreement") between the
BRI Partnership and the Transferor Company and Transferor Members. To facilitate
the transactions contemplated hereby and by the Other Avalon Agreement, prior to
the commencement of construction, the Transferor Company will transfer either or
both of the Land and the Additional Land to a newly-formed limited
partnership(s) or limited liability company(s) such that the Land will be owned
by one entity and the Additional Land will be owned by another entity. At said
time, the newly-formed entity(s) and its owners will assume all of the
obligations of either this Agreement or the Other Avalon Agreement (whichever is
applicable to the land it then owns) and the original Transferor Company and
Transferor Members shall be released from all liability thereunder, and pursuant
to instruments in form reasonably satisfactory to all parties.

         18.02 Integration. This Agreement and the Schedules and Exhibits hereto
embody and constitute the entire understanding between the parties with respect
to the transactions contemplated herein, and all prior agreements,
understandings, representations and statements, oral or written, are merged into
this Agreement. Neither this Agreement nor any provision hereof may be waived,

   2.01 Loan. By and subject to the terms of this Agreement, Lender agrees to
lend and Borrower agrees to borrow on the Closing Date the principal sum of
SEVEN MILLION FIVE HUNDRED THOUSAND AND 00/100 DOLLARS ($7,500,000.00) or such

Partnership Units or Common Stock pledged as security for the Loan on either (a)
the Closing Date or (b) to the extent provided in Section 2.06, any Semi-Annual
Loan Review Date. The value of the Partnership


                                      -3-

<PAGE>

Units and Common Stock shall be determined in accordance with the provisions of
Section 2.07 hereof.

   2.06 Release of Security. On a semi-annual basis, commencing on the date
which is six months after the Closing (each such date being referred to herein
as a "Semi-Annual Loan Review Date"), the number of pledged Partnership Units or
shares of Common Stock or other collateral held by Lender pursuant to Section
5(a) or 5(c) of the Pledge Agreement shall be reduced to reflect the decrease,
if any, in the outstanding principal balance of the Loan, provided that no such
reduction shall be made to the extent that it would cause the outstanding
principal balance of the Loan on any such Semi-Annual Review Date to be less
than eighty percent (80%) of the value of the Partnership Units or Common Stock
or other collateral held by Lender pursuant to Section 5(a) or 5(c) of the
Pledge Agreement which would remain pledged as security for the Loan on such
date (as such value is determined in accordance with the provisions of Section
2.07(b) hereof).

   2.07 Calculation of Loan to Value Ratio.

        (a) For purposes of establishing the value of Partnership Units on the
Closing Date, the value of each Partnership Unit shall be the offering price per
share ("Offering Price"), rounded to the nearest one-thousandth, of one share of
Common Stock of BRI as such price is established at the closing of the Public
Offering. If such calculation provided would result in the pledge of a
fractional Partnership Unit under Section 2.05 hereof, the required number of
Partnership Units to be pledged shall be rounded up or down, as the case may be,
to the nearest whole number of Partnership Units.

        (b) For purposes of establishing the value of Partnership Units and
Common Stock on each Semi-Annual Loan Review Date, the value of each Partnership
Unit or share of Common Stock shall be the average price per share during the
ten (10) day period immediately preceding the applicable Semi-Annual Loan Review
Date, rounded to the nearest one-thousandth, of one share of Common Stock of
BRI. If such calculation would result in the release of a fractional Partnership
Unit under Section 2.06 hereof, the required number of Partnership Units or
shares of Common Stock (if any) to be released shall be rounded up or down, as
the case may be, to the nearest whole number of Partnership Units or shares of
Common Stock.

                              CONDITIONS PRECEDENT

   3.01 Lender's Conditions Precedent. Lender shall not be obligated to make any
disbursement hereunder or to take any other action under the Loan Documents
unless all of the following conditions precedent are satisfied at the time of
such action:

        (a) Delivery of Loan Documents. Borrower and the Guarantors have
            delivered to Lender each of the following loan documents (the "Loan
            Documents"):

            (i)    The Promissory Note;

            (ii)   The Pledge Agreement;

            (iii)  The Financing Statements for each filing office required to
                   perfect Lender's security interest in the Collateral;

            (iv)   The Guaranty; and

            (v)    Such other documents, certificates and instruments as Lender
                   may reasonably require in connection with the Loan.

        (b) Public Offering. Lender has informed Borrower that in connection
            with the consummation of the various Related Transactions, Lender
            intends to undertake either or both of (i) a public offering (the
            "Public Offering") of common stock or other equity securities of
            Lender (the "Common Stock"), or (ii) a private placement of Common
            Stock (the "Private Placement"). Borrower shall supply any
            documentation and additional information reasonably required by
            Lender in order to complete the offering materials in connection
            with the Public Offering or the Private Placement. The obligation of
            Lender 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 dollars. If the Public Offering and
            Private Placement do not in the aggregate complete offerings which
            raise a minimum of $75,000,000.00 as aforesaid prior to the Closing
            Date hereunder, Lender shall have the right to terminate this
            Agreement effective

<PAGE>

            as of the Closing Date hereunder, 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.

        (c) Related Agreements. Simultaneously herewith, Lender has entered into
            certain agreements, more particularly described on Schedule 4
            attached hereto (collectively the "Related Agreements"). (The
            transactions described in the Related Agreements, including this
            Agreement, are collectively referred to herein as the "Related
            Transactions"). Except to the extent the parties expressly agree
            otherwise in writing, in the event that any of the Related
            Agreements is terminated pursuant to any termination provision of
            any other Related Agreement, this Agreement shall terminate
            automatically simultaneously with the termination of any such
            Related Agreement, 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 (as such term is defined in the Related Agreements), 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.

        (d) Opinion of Borrower's and Guarantors' Counsel. Lender shall have
            received the favorable opinion of counsel to Borrower and the
            Guarantors, or such other evidence as Lender may reasonably require
            (i) that Borrower has been duly formed in accordance with Maryland
            law and is validly existing and in good standing under such laws,
            (ii) that the Loan Documents executed by Borrower have been duly
            executed and delivered and constitute the valid, legal and binding
            obligation of Borrower, enforceable in accordance with their terms,
            subject only to bankruptcy laws and matters of equitable
            jurisdiction, (iii) that the Guaranty, the Pledge Agreement and any
            other Loan Documents executed by the Guarantors have been duly
            executed and delivered and constitute the valid, legal and binding
            obligation of the Guarantors, enforceable in accordance with their
            terms, subject only to bankruptcy laws and matters of equitable
            jurisdiction, (iv) that the Guarantors are all of the members of
            Borrower, (v) that Lender has a valid, enforceable and perfected
            security interest in the Collateral, (vi) that, to the best of such
            counsel's knowledge, the execution, delivery and performance by the
            Borrower and the Guarantors of the Loan Documents to which each is a
            party do not conflict with, violate or breach any provision of the
            organizational documents of Borrower or any agreement or indenture
            by which either the Borrower or any of the Guarantors may be bound,
            or any judgments or awards

            specifically naming the Borrower or any of the Guarantors or
            specifically applicable to their respective property, (vii) that, to
            the best of such counsel's knowledge, there is no action, suit or
            proceeding, pending or threatened against the Borrower or any of the
            Guarantors, which, if adversely determined, would impair the
            validity or enforceability of the Loan Documents, and (viii) that
            except for the filing of the Financing Statements with the
            applicable filing offices, (and except as may be required in
            connection with any Blue Sky or other securities laws, codes, rules
            or regulations applicable to the issuance of the Collateral to the
            Guarantors by Lender) no approval, consent, order or authorization

<PAGE>

   8.05 Relationship of Parties. The relationship of Borrower and Lender under
the Loan Documents is, and shall at all times remain, solely that of Borrower
and Lender. Lender neither undertakes nor assumes any responsibility or duty to
Borrower or to any third party with respect to the Collateral, except as
expressly provided in the Loan Documents.

   8.06 Attorneys' Fees; Enforcement. If any attorney is engaged by Lender to
enforce or defend any provision of this Agreement or any of the other Loan
Documents, or as a consequence of any Event of Default under the Loan Documents,
with or without the filing of any legal action or proceeding, Borrower shall pay
to Lender, immediately upon demand, the amount of all reasonable attorneys' fees
and costs incurred by Lender in connection therewith, together with interest
thereon from the date of such demand until paid at the rate of interest
applicable to the principal balance of the Note as specified therein.

   8.07 Assignment. Borrower shall not assign Borrower's interest under any of
the Loan Documents, or in any monies due or to become due thereunder, without

incorporate by reference the entire agreement of the parties with respect to the
matters contemplated herein and supersede all prior negotiations. Any reference
to the Loan Documents in any of the Loan Documents includes any amendments,
renewals or extensions approved by Lender. Any reference in this Agreement to
the Loan Documents shall include all or any of the provisions of the Agreement
and the Loan Documents unless otherwise specified.

   8.09 Joint and Several Liability. The liability of all persons or entities
who are in any manner obligated under the Note or any other Loan Document shall
be joint and several.

   8.10 Severability. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

   8.11 Paragraph Headings. The paragraph headings used in this Agreement are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

   8.12 No Waiver; Cumulative Remedies. Lender shall not by any act (except by a
written instrument pursuant to Section 8.13 hereof), delay, indulgence, omission


                                      -11-

<PAGE>

or otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any default or Event of Default or in any breach of any of the
terms and conditions hereof. No failure to exercise, nor any delay in
exercising, on the part of Lender, any right, power or privilege hereunder shall
operate as a waiver thereof. No single or partial exercise of any right, power
or privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. A waiver by Lender of any
right or remedy hereunder on any one occasion shall not be construed as a bar to
any right or remedy which Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently and are not exclusive of any rights or remedies provided by law.

   8.13 Waivers and Amendments; Successors and Assigns; Governing Law. None of
the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except by a written instrument executed by the Lender and
Borrower, provided that any provision of this Agreement may be waived by Lender
in a letter or agreement executed by Lender or by facsimile transmission from
Lender. This Agreement shall be binding upon the successors and assigns of the
Borrower and shall inure to the benefit of Lender and its successors and
assigns. This Agreement shall be governed by, and construed in accordance with,
the laws of the State of Maryland; provided, however, that any suit in
connection with any dispute arising out of or relating to this Agreement shall
be brought only in the federal and state courts of the Commonwealth of
Massachusetts. Borrower and Lender consent to the personal jurisdiction of the
federal and state courts of the Commonwealth of Massachusetts and agree that
service of process may be made upon each of them by certified mail, return
receipt requested or in any other manner permitted by law.

   8.14 Notices. Whenever notice, demand or a request under this Agreement may
properly be given to Lender or Borrower, the same shall be in writing and shall
be (a) hand delivered to the party intended to receive the same, or (b) sent by
registered or certified mail, postage prepaid, return receipt requested,
addressed to the parties at their respective addresses as set forth below:

   (e) Each of the Company and its Subsidiaries is duly qualified to do business
and in good standing in each jurisdiction in which the ownership of its property
or the conduct of its business requires such qualification, except as set forth
in Schedule 3.1(e).

   (f) Schedule 3.1(f) sets forth the name of each Subsidiary of the Company or
the Operating Partnership (whether owned directly or indirectly through one or
more intermediaries). All of the outstanding shares of capital stock of, or
other equity interest in, each of the Subsidiaries owned by the Company or the

nonassessable, and are owned, directly or indirectly, by the Company or the
Operating Partnership free and clear of all Liens, except as set forth in
Schedule 3.1(f). The following information for each Subsidiary is set forth in
Schedule 3.1(f), if applicable: (i) its name and jurisdiction of incorporation
or organization, (ii) the type of and percentage interest held by the Company or
Operating Partnership in the Subsidiary and, in the case of Subsidiaries, the

subscriptions, convertible securities or other rights, agreements or commitments
which obligate the Company or any of the Subsidiaries to issue, transfer or sell

   Section 3.2 "Authority Relative to Agreements; Board Approval." (a) The
execution, delivery and performance of this Agreement, the Registration Rights
Agreement, and the Certificate of Designation, the issuance of shares of Company
Preferred Stock in accordance herewith and the Certificate of Designation, and
the issuance and delivery of shares of Company Common Stock upon conversion of
shares of Company Preferred Stock in accordance with the provisions of the
Certificate of Designation, have been duly and validly authorized by all
necessary corporate action on the part of the Company and all necessary
partnership action on the part of the Operating Partnership. This Agreement has
been duly executed and delivered by the Company for itself and constitutes the

apply to the Company Stock held or to be held by Buyer or the Advancing Party,
and the Company has declined, now and for all times in the future, any offer
deemed to have been made by Buyer or the Advancing Party pursuant to said
paragraph B, and agreed that Buyer and the Advancing Party will for no purpose
be deemed to be a "Group Acting in Concert," or portion thereof, or "Interested
Shareholder," in each case 


                                       9

Buyer hereunder or purchaser from Buyer of shares of Company Stock shall be
entitled, as to itself, to the benefits of such Board of Directors' action
without a subsequent action specifically referencing such assignee or purchaser
of Company Stock.

   (c) The shares of Company Preferred Stock to be acquired pursuant to this

an immaterial change in the number of Company Stock outstanding. All such issued
and outstanding shares of Company Common Stock are duly authorized, validly
issued, fully paid, nonassessable and free of preemptive rights. The Company has
no outstanding bonds, debentures, notes or other obligations the holders of
which have the right to vote (or which are convertible into or exercisable for
securities the holders of which have the right to vote) with the stockholders of
the Company on any matter. Other than (i) Operating Partnership Units which may
be redeemed by the holders thereof for Company Common Stock or the cash
equivalent thereof (at the option of the General Partner), or (ii) as set forth
in Schedule 3.3(a) to this Agreement, there are no existing options, warrants,
calls, subscriptions, convertible securities, or other rights, agreements or
commitments which obligate the Company to issue, transfer or sell any shares of
capital stock or other equity interests of the Company.

other form of general or limited partnership interest, of the Operating
Partnership issued or outstanding as of the date hereof. Except as set forth in
Schedule 3.3(b), the Operating Partnership has not issued or granted securities
convertible into interests in the Operating Partnership, and is not a party to
any outstanding commitments of any kind relating to, or any presently effective
agreements or understandings with respect to, interests in Operating
Partnership, whether issued or unissued. Since August 31, 1997, there have been
no changes to the number of Operating Partnership Units outstanding. On
September 22, 1997, the Operating Partnership anticipates it will issue 95,620
Operating Partnership Units in connection with a previously approved acquisition
transaction.

   (c) Except for interests in the General Partner, the Subsidiaries of the
Company, the Operating Partnership, and its joint venture interest in the Spring
Valley Joint Venture, none of the Company or any of its Subsidiaries owns
directly or indirectly any interest or investment (whether equity or debt) in
any corporation, partnership, joint venture, business, trust or entity (other
than investments in short-term investment securities).

   (d) The direct or indirect, beneficial or record, ownership of Douglas Krupp
and David F. Marshall, respectively, in Company Common Stock or Operating
Partnership Units is as set forth in Schedule 3.3(d).

accelerate the performance required by, or result in the creation of any Lien
upon any of the properties of the Company or its Subsidiaries under, or result
in being declared void, voidable or without further binding effect, any of the
terms, conditions or provisions of any note, bond, mortgage, indenture, deed of
trust or any license, franchise, permit, lease, contract, agreement or other
instrument, commitment or obligation to which the Company or its Subsidiaries is
a party, or by which the Company or its Subsidiaries or any of their properties
is bound or affected; or

   (f) except as set forth in Schedule 3.4(f), require any consent, approval or

amended (the "Securities Act"), the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), the Hart-Scott-Rodino Antitrust Improvements Act of 1976
(the "HSR Act"), state securities laws ("Blue Sky Laws") (collectively, the
"Regulatory Filings"), and any filings required to be made with the Office of
the Secretary of the State of Delaware and NYSE or any other national securities
exchange on which the Company Common Stock is listed.

   Section 3.5 "SEC and Other Documents, Financial Statements; Undisclosed
Liabilities." (a) The Company has delivered or made available to Buyer, or there
are commercially available to Buyer in the ordinary course, the registration
statement of the Company filed with the Securities and Exchange Commission
("SEC") in connection with the Company's exchange offering of Company Common
Stock for all the assets and liabilities of certain limited partnerships and the
subsequent distribution of such Company Common Stock to the limited partners
thereof, and all exhibits, amendments and supplements thereto (collectively, the
"Company Registration Statement"), and each registration statement, report,
proxy statement or information statement and all exhibits thereto prepared by it
or relating to its properties since the effective date of the Company
Registration Statement, which are set forth in Schedule 3.5(a), each in the form
(including exhibits and any amendments thereto) filed with the SEC
(collectively, the "Company Reports"). The Company Reports were filed with the
SEC in a timely manner and constitute all forms, reports and documents required
to be filed by the Company under the Securities Act, the Exchange Act and the
rules and regulations promulgated thereunder (the "Securities Laws"). As of
their respective dates, the Company Reports (i) complied as to form in all
material respects with the applicable requirements of the Securities Laws and
(ii) did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading; provided, however, that as to the compliance of the Company Reports
with the requirements of the Securities Laws, insofar as such representation is
made as to matters of form established in the Securities Laws, and assuming that
such Company Reports were prepared under the direction of


                                       11

<PAGE>

and with the advice of independent counsel and auditors to the Company, it is a
representation made to the company's Knowledge. There is no unresolved violation
or position asserted by any Government Authority with respect to any of the
Company Reports except as set forth in Schedule 3.5(a) with respect to the
Company's intended position in response to that certain letter of August 14,
1997, from the SEC (but excluding comments 9 and 11 therein, as to which the
Company has reached resolution as set forth in Schedule 3.5(a)). No such
unresolved violation or position (again, excluding comments 9 and 11 referred to
above) is or could be material to the Company or its business, operations or
financial position, nor could it reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect.

   (b) Except as set forth in Schedule 3.5(b), each of the balance sheets
included in or incorporated by reference into the Company Reports (including the
related notes and schedules) fairly presented the financial position of the

and schedules) fairly presented the results of operations, retained earnings or
cash flows, as the case may be, of the entity or entities to which it relates
for the periods set forth therein, in each case in accordance with United States
generally accepted accounting principles ("GAAP") consistently applied during
the periods involved except as may be noted therein and except, in, the case of
the unaudited statements, normal recurring year-end adjustments.

   (c) Except as and to the extent set forth in the Company Reports or any
Schedule hereto, none of the Company or any of its Subsidiaries has any
Liabilities (nor do there exist any circumstances that would result in any
Liabilities).

   Section 3.6 "Litigation, Compliance With Law." (a) Except as disclosed in
Schedule 3.6(a), there are no Actions pending or threatened against the Company
or any of its Subsidiaries which question the validity hereof or any action
taken or to be taken in connection herewith, and there are no continuing orders,
injunctions or decrees of any Government Authority to which the Company or any
of its Subsidiaries is a party or by which any of its properties or assets are
bound.

   (b) To the Company's Knowledge, none of the Company or its Subsidiaries is in
violation of any statute, rule, regulation, order, writ, decree or injunction of
any Government Authority or any body having jurisdiction over them or any of
their respective properties, except as could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect, and except
as set forth in Schedule 3.6(b).

   Section 3.7 "Absence of Certain Changes or Events." Except as disclosed in
the Company Reports filed with the SEC prior to the date hereof or in Schedule
3.7, since December 31, 1996, the Company and each of its Subsidiaries has
conducted its business only in the ordinary course of such business and has not
acquired any real estate or entered into any financing arrangements in
connection therewith, and there has not been (a) any change, circumstance or
event that would reasonably be expected to result in an adverse effect on the
business, operations or condition (financial or otherwise) of the Company, the
Operating Partnership and the Subsidiaries, considered as a whole, (b) any
declaration, setting aside or payment of any dividend or other distribution with
respect to the Company Common Stock, except in accordance with Section 5.5, (c)
any commitment, contractual obligation, borrowing, capital expenditure or

Subsidiaries, or (d) any change in the Company's accounting principles,
practices or methods. The Company is not now contemplating entering into any
Commitment which, had it occurred on or before the date hereof would be required
to be disclosed in the Company Reports or in Schedule 3.7.

   Section 3.8 "Tax Matters; REIT and Partnership Status." (a) The Company and
each of its Subsidiaries has timely filed with the appropriate taxing authority
all Tax Returns required to be filed by it or has timely requested extensions
and any such request has been granted and has not expired. Each such Tax Return
is complete and accurate in all respects. All Taxes shown as owed by the Company
or any of its Subsidiaries on any Tax Return have been paid or accrued, except
for Taxes being contested in good faith and for which adequate reserves have
been taken. The Company and each of its Subsidiaries has properly accrued all
Taxes for such periods subsequent to the periods covered by such Tax Returns as

<PAGE>

any of its Subsidiaries has executed or filed with the IRS or any other taxing
authority any agreement now in effect extending the period for assessment or
collection of any Tax. Except as set forth in Schedule 3.8(a), none of the
Company or any of its Subsidiaries is a party to any pending action or
proceedings by any taxing authority for assessment or collection of any Tax, and
no claim for assessment or collection of any Tax has been asserted against it.
True and complete copies of all federal, state and local income and franchise
Tax Returns, or any extensions applicable thereto, filed by the Company and each
of its Subsidiaries for the taxable years 1994 to the present and all
communications relating thereto, have been delivered to Buyer or have been made
available to its representatives. To the Company's Knowledge, no claim has been
made by an authority in a jurisdiction where the Company or any of its
Subsidiaries does not file Tax Returns that it is or may be subject to taxation
by that jurisdiction. Except as set forth in Schedule 3.8(a), there is no
dispute or claim concerning any Tax liability of the Company or any of its
Subsidiaries claimed or raised by any taxing authority in writing. As of the
date hereof, (i) the Company is a "domestically-controlled" REIT within the
meaning of Code Section 897(h)(4)(B), and (ii) all non-domestic beneficial
owners of Company Common Stock are set forth in Schedule 3.8(a). Except as set
forth in Schedule 3.8(a), no person or entity which would be treated as an
"individual" for purposes of Section 542(a)(2) of the Code (as modified by
Section 856(h) of the Code) owns or would be considered to own (taking into
account the ownership attribution rules under Section 544 of the Code, as
modified by Section 856(h) of the Code) in excess of 9.8% of the value of the
outstanding equity interest in the Company. The Company is not "Pension-Held
REIT" within the meaning of Section 856(h)(3)(D) of the Code.

   (b) The Company (i) intends in its federal income tax return for the tax year
ended December 31, 1997 and for the tax year that will end on December 31, 1998
to elect to be taxed as a real estate investment trust within the meaning of
Section 856 of the Code ("REIT") and has complied (or will comply) with all
applicable provisions of the Code relating to a REIT, (ii) has operated, and
intends to continue to operate, in such a manner as to qualify as a REIT, (iii)
has not taken or omitted to take any action which would reasonably be expected
to result in a challenge to its status as a REIT, and no such challenge is
pending or threatened, and (iv) assuming the accuracy of Buyer's representation
in Section 4.7, will not be rendered unable to qualify as a REIT for federal
income tax purposes as a consequence of the transactions contemplated hereby.

   (c) Any amount or other entitlement that could be received (whether in cash
or property or the vesting of property) as a result of any of the transactions
contemplated hereby by any employee, officer, or director of the Company or the
Operating Partnership or any of their Affiliates who is a "disqualified
individual" (as such term is defined in proposed Treasury Regulation Section
1.280G-1) under any employment, severance or termination agreement, other
compensation arrangement or plan currently in effect would not be characterized
as an "excess parachute payment" (as such term is defined in Section 280G(b)(1)
of the Code).

   (d) The disallowance of a deduction under Section 162(m) of the Code for
employee remuneration will not apply to any amount paid or payable by the
Company or any of its Subsidiaries under any contract, stock plan, program,
arrangement or understanding currently in effect.

   (e) The Company was eligible to and did validly elect to be taxed as a REIT
for federal income tax purposes for calendar year 1991 and all subsequent
taxable periods. The Operating Partnership and each Subsidiary of the Company
and the Operating Partnership organized as a partnership (and any other
Subsidiary that files Tax Returns as a partnership for federal income tax
purposes) was and continues to be classified as a partnership for federal income
tax purposes.

   Section 3.9 "Compliance with Agreements." (a) Neither the Company nor any of
its Subsidiaries is in default under or in violation of any provision of the
Company Charter, the By-laws of the Company or the Partnership Agreement (or
equivalent documents), except as set forth in Schedule 3.9(a).

   (b) The Company and each of its Subsidiaries have filed all material reports,
registrations and statements, together with any amendments required to be made
with respect thereto, that they were required to be with any Government
Authority and all other material reports and statements required to be filed by
them, including any report or statement required to be filed pursuant to the
laws, rules or regulations of the United States, and have 


                                       13

<PAGE>

paid all fees or assessments due and payable in connection therewith, except as
set forth in Schedule 3.9(b). There is no unresolved violation asserted by any
regulatory agency, nor has the Company received notice from any regulatory
agency with respect to any report or statement relating to an examination of the
Company or any of its Subsidiaries.

   (c) The Company Reports or Schedule 3.9(c) set forth (i) a description of all
material indebtedness of the Company and each of its Subsidiaries, whether
unsecured, secured or collateralized by mortgages, deeds of trust or other
security interests in the Company Properties or any other assets of the Company
and each of its Subsidiaries, or otherwise and (ii) each Commitment entered into
by the Company or any of its Subsidiaries (including any guarantees of any third
party's debt or any obligations in respect of letters of credit issued for the
Company's or any Subsidiary's account) which may result in total payments or
liability in excess of $250,000, excluding Commitments made in the ordinary
course of business with a maturity of less than one year or that are terminable
on 30 days or less notice. True and complete copies of the foregoing have been
delivered or made available to Buyer or to its representatives. Neither the
Company nor any of its Subsidiaries is in default and no event has occurred
which, with the giving of notice or the lapse of time or both, would constitute
a default, under any of the documents described in clause (i) or (ii) of this
paragraph or in respect of any payment obligations thereunder. All joint venture
and partnership agreements to which the Company or any of its Subsidiaries is a
party as of the date hereof are set forth in Schedule 3.9(c), all of which are
in full force and effect as against the Company or such Subsidiary and as
against the other parties thereto, and none of the Company or any of its
Subsidiaries is in default and no event has occurred which, with the giving of
notice or the lapse of time or both, would constitute a default, with respect to
any obligations thereunder. The other parties to such agreements are not in
breach of any of their respective obligations thereunder.

   (d) Except as disclosed in the Company Reports or any other Schedule hereto,
and except as could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect, Schedule 3.9(d) sets forth a
complete and accurate list of all agreements entered into by the Company or any
of its Subsidiaries as of the date hereof relating to the development or
construction of, additions or expansions to, or management or leasing services
for real properties which are currently in effect and under which the Company or
any of its Subsidiaries currently has, or expects to incur, any material
obligation. True and complete copies of such agreements will be delivered or
made available to Buyer within five Business Days from the date hereof.

   (e) Except as disclosed in the Company Reports, and except for agreements
made in the ordinary course of business with a maturity of less than one year or
that are terminable on 30 days or less notice, and except as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, Schedule 3.9(e) sets forth a complete and accurate list of all
agreements entered into by the Company as of the date hereof which are not
listed in any other Schedule hereto, including the material Debt Instruments.
Each agreement set forth in Schedule 3.9(e) is in full force and effect as
against the Company and, as against the other parties thereto, no payments, if
any, thereunder are delinquent, and no notice of default thereunder has been
sent or received by the Company or any of its Subsidiaries. There does not exist
under any agreement set forth in Schedule 3.9(e) any default, and no event has
occurred which, with notice or lapse of time or both, would constitute such a
default. True and complete copies of each such agreement have been delivered or
made available to Buyer.

   (f) Schedule 3.9(f) sets forth a complete and accurate list of all
agreements, with their respective costing in spread sheet form, and policies (in
the case of policies which are not manifested by written agreement, Schedule
3.9(f) shall include a correct and complete written summary thereof) of the
Company in effect on the date hereof relating to transactions with affiliates
and potential conflicts of interest, excluding agreements with Partnership
Affiliates (defined below), but including such agreements with and such policies
relating to all Affiliates of the Company, including but not limited to The
Berkshire Group, and Affiliates of The Berkshire Group, Laurence Gerber, Douglas
Krupp, George Krupp, David Marshall, and any Affiliate of a predecessor
organization of The Berkshire Group, or any of such Persons. Each agreement or
policy set forth in Schedule 3.9(f) is in full force and effect, and the
Company, each of its Subsidiaries, and the other parties thereto are in
compliance with such agreements and policies, or such compliance has been waived
by the Board of Directors as set forth in Schedule 3.9(f). True and complete
copies of each such agreement or policy have been delivered to Buyer or to its
representatives. As used herein, "Partnership Affiliate" means any limited
partnership in which a predecessor 


                                       14

<PAGE>

organization of The Berkshire Group, Douglas Krupp, George Krupp, or any of them
or their Affiliates, directly or indirectly, hold a general or limited partner
interest which is in no event less than or equal to 1% of the effective economic
interest in any such partnership, nor will any partnership interest in any such
partnership now or in the future held, directly or indirectly, by The Berkshire
Group, Douglas Krupp, George Krupp, or any of them or their Affiliates, with the
passage of time or the occurrence of any event, or both, exceed 1% of any such
effective economic interest.

   Section 3.10 "Financial Records; Company Charter and By-laws; Corporate
Records." (a) The books of account and other financial records of the Company
and each of its Subsidiaries are in all respects true and complete, have been
maintained in accordance with good business practices, and are accurately
reflected in all respects in the financial statements included in the Company
Reports, except as set forth in Schedule 3.10(a).

   (b) The Company has previously delivered or made available to Buyer true and
complete copies of the Company Charter and the By-laws of the Company, as
amended to date, the Partnership Agreement, and the charter, by-laws,
organization documents, partnership agreements and joint venture agreements of
the Subsidiaries, and all amendments thereto. All such documents are listed in
Schedule 3.10(b). A chart of the Company, the Operating Partnership, and the
Subsidiaries showing ownership, voting or general partner rights and contractual
relationships is set forth in Schedule 3.10(b).

   (c) The minute books and other records of corporate or partnership
proceedings of the Company and each of its Subsidiaries have been made available
to Buyer, contain in all material respects accurate records of all meetings and
accurately reflect in all material respects all other corporate action of the
stockholders and directors and any committees of the Board of Directors of the
Company and their Subsidiaries which are corporations and all actions of the
partners of the Operating Partnership and Subsidiaries which are partnerships,
except for documentation of discussions relating to or in connection with the
transactions contemplated hereby or matters related hereto, except as set forth
in Schedule 3.10(c).

   Section 3.11 "Properties." (a) Schedule 3.11(a) sets forth a complete and
accurate list and the address of all real property directly or indirectly owned,
all or in part, or leased by the Company or any of its Subsidiaries or otherwise
used by the Company or its Subsidiaries in the conduct of their business or
operations (collectively, and together with the land at each address referenced
in Schedule 3.11(a) and all buildings, structures and other improvements and
fixtures located on or under such land and all easements, rights and other
appurtenances to such land, the "Company Properties"), other than the office
space leased by the Company from which the Company operates its business which
is listed separately on Schedule 3.11(a) as HQ Space (the "HQ Space"). The
Operating Partnership or, in the case of Company Properties owned by
Subsidiaries, certain of the Subsidiaries, owns good and marketable fee simple
title (or, if so indicated in Schedule 3.11(a), leasehold title) to each of the
Company Properties, in each case free and clear of any Liens, title defects,
contractual restrictions or covenants, laws, ordinances or regulations affecting
use or occupancy (including zoning regulations and building codes) or
reservations of interests in title (collectively, "Property Restrictions"),
except for (i) Permitted Liens and (ii) Property Restrictions imposed or
promulgated by law or by any Government Authority which are customary and
typical for similar multi-family residential or commercial properties. None of
the matters described in clauses (i) and (ii) of the immediately preceding
sentence materially interferes with, impairs, or is violated by, the existence
of any building or other structure or improvement which constitutes a part of,
or the present use, occupancy or operation (or, if applicable, development) of
the Company Properties taken as a whole. Except as set forth in Schedule 3.11(a)
and as to the Development Properties for which application for title policies
have been or are being made in the ordinary course and as to which the Company
has no reason to believe will not issue on customary terms and in customary and
marketable form (without exceptions which would render the subject Development
Properties unfinanceable), policies of title insurance (issued on customary
American Land Title Association forms) have been issued by national title
insurance companies insuring the fee simple or leasehold, as applicable, title
of the Operating Partnership or its Subsidiaries, as applicable, to each of the
Company Properties in amounts at least equal to the original cost thereof
subject only to Permitted Liens; such policies are valid and in full force and
effect and no claim has been made under any such policy, and the Company is not
aware of any fact or information which would constitute a defense by the issuer
of any such policy or an exclusion from coverage. True and complete 


                                       15

<PAGE>

copies of all such policies together with all exceptions referenced therein and
the most recent title reports for and surveys of each of the Company Properties
available to the Company or any of its Subsidiaries have been made available by
the Company to Buyer or to its representatives.

   (b) Except as set forth in Schedule 3.11(b), and except as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the use or occupancy (or, if applicable, development or
maintenance) of the Company Properties, any currently required certificate,
permit or license (including building permits and certificates of occupancy for
tenant spaces) from any Government Authority having jurisdiction over any
Company Property or any agreement, easement or other right which is necessary to
permit the lawful use, occupancy or operation of the existing buildings,
structures or other improvements which constitute a part of any of the Company
Properties or which are necessary to permit the lawful use and operation of
utility service to any Company Property or of any existing driveways, roads or
other means of egress and ingress to and from any of the Company Properties has
been obtained and is in full force and effect, and there are no pending threat
of modification or cancellation of any of same, and there is no violation by any
Company Property of any federal, state or municipal law, ordinance, order,
regulation or requirement, including any applicable zoning law or building code,
as a result of the use or occupancy of such Company Property or otherwise.
Except as set forth in Schedule 3.11(b), there is no uninsured physical damage
to any Company Property in excess of $100,000. Except for repairs identified in
the Capital Expenditure Budget and Schedule, each Company Property, (i) is in
good or better operating condition and repair and is structurally sound and free
of defects, with no material alterations or repairs being required thereto under
applicable law or insurance company requirements, and (ii) consists of
sufficient land, parking areas, driveways and other improvements and lawful
means of access and utility service and capacity to permit the use thereof in
the manner and for the purposes to which it is presently devoted (or, in the
case of the Development Property, for the development and operation thereon of
the applicable Project), except, in each such case, to the extent that failure
to meet such standards would adversely affect the use or occupancy of the
Company Properties taken as a whole (or, in the case of the Development
Property, the development and operation thereon of the applicable Project). The
Company has made available to Buyer or to its representatives true and complete
copies of all engineering reports, inspection reports, maintenance plans and
other documents relating to the condition of any Company Property prepared for
the Company or otherwise in the Company's or any Subsidiary's possession.

   (c) Except as set forth in Schedule 3.11(c), and, except as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, (i) no condemnation, eminent domain or rezoning proceedings are
pending or threatened with respect to any of the Company Properties, (ii) no
road widening or change of grade of any road adjacent to any Company Property is
underway or has been proposed, (iii) no proposed change in the assessed
valuation of any Company Property, (iv) no special assessment has been made or
threatened against any Company Property, and (v) no Company Properties are
subject to any so-called "impact fee" or to any agreement with any Government
Authority to pay for sewer extension, oversizing utilities, lighting or like
expenses or charges for work or services by such Government Authority.

   (d) Each of the Company Properties is an independent unit which does not rely
on any facilities located on any property not included in such Company Property
to fulfill any municipal or governmental requirement or for the furnishing to
such Company Property of any essential building systems, utilities or customary
amenities, other than facilities the benefit of which inures to the Company
Properties pursuant to one or more valid easements, or facilities which are
located on or abutting Company Properties and are sufficient to serve more than
one property adequately and lawfully. Each of the Company Properties is served
by public water and sanitary systems and all other utilities, and each of the
Company Properties has lawful access to public roads, in all cases sufficient
for the current use and occupancy of each Company Property (or, in the case of
the Development Property, for the development and operation thereon of the
applicable Project). All parcels of land included in each Company Property that
purport to be contiguous are contiguous and are not separated by strips, gaps or
gores. No portion of any Company Property lies in any flood plain area (as
defined by the U.S. Army Corps of Engineers or otherwise) or includes wetlands
or vegetation or species protected by any applicable laws. No improvements
constituting a part of any Company Property encroach on real property not
constituting a part of such Company Property or an abutting Company Property.

   (e) The Company has supplied or made available to Buyer each survey, study or
report prepared by or for the Company or any of the Subsidiaries in connection
with any Company Property's compliance or non-compliance with the requirements
of the Americans with Disabilities Act (the "ADA"), other than routine
correspondence or memoranda. Except as set forth in Schedule 3.11(e), and except
as could not, individually or in the aggregate, be reasonably expected to result
in a Material Adverse Effect, no Company Property fails to comply with the
Requirements of the ADA.

   (f) The Company has provided to Buyer an accurate rent roll for each Company
Property (collectively, the "Rent Rolls") as of the month ended July 31, 1997
all of which remain true, correct and complete as of the date hereof, except for
immaterial variations in the ordinary course of business, which identifies and
accurately describes each lease of space in each Company Property (collectively,
the "Company Leases") and sets forth the vacancy for each.

   (g) Schedule 3.11(g) sets forth a complete and accurate list of all material
commitments, letters of intent or similar written understandings made or entered
into by the Company or any of its Subsidiaries as of the date hereof (x) to
lease any space larger than 25,000 rentable square feet at any of the Company
Properties, (y) to sell, mortgage, pledge, hypothecate any Company Property or
to otherwise enter into a material transaction in respect of the ownership or
financing of any Company Property, or (z) to purchase or acquire an option,
right of first refusal or similar right in respect of any real property, which,
in any such case, has not yet been reduced to a written lease or contract, and
sets forth with respect to each such commitment, letter of intent or other
understanding the principal terms thereof. The Company has previously delivered
or made available to Buyer a true and complete copy of each such commitment,
letter of intent or other understanding.

   (h) Except as set forth in Schedule 3.11(h), the Company, the Operating
Partnership and all the Subsidiaries have the right, including, but not limited
to, to sell, transfer, lease, finance, without limitation, all of the Company
Properties. Except for certain rights of first refusal which are set forth in
the sections of the partnership agreements referenced in Schedule 3.1(e) and
which relate to partnerships in which the Company, directly or indirectly, owns
less than a 100% interest, none of the Company or any of its Subsidiaries has
granted any outstanding options or has entered into any outstanding contracts
with others for the sale, mortgage, pledge, hypothecation, assignment, sublease,
lease or other transfer of all or any part of any Company Property, and no
person has any right or option to acquire, or right of first refusal with
respect to, the Company's or any of its Subsidiaries' interest in any Company
Property or any part thereof. Except as set forth in Schedule 3.11(h) none of
the Company or any of its Subsidiaries has any outstanding options or rights of
first refusal or has entered into any outstanding contracts with others for the
purchase of any real property.

   (i) Schedule 3.11(i) contains a complete and accurate description of any
noncompliance by any Company Property, with any law, ordinance, code, health and
safety regulation or insurance requirement (except for the ADA, which is
addressed in this respect in Section 3.11(e) above), except as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. The Company has provided the Company's or any Subsidiary's
capital expenditure budget and schedule for each Company Property (the "Capital
Expenditure Budget and Schedule"), which describes the capital expenditures
which the Company or any Subsidiary has budgeted for such Company Property for
the period running through at least December 31, 2002, and such other capital
expenditures as are necessary in order to bring such Company Property into
compliance with applicable laws, ordinances, codes, health and safety
regulations and insurance requirements (including fire sprinklers, compliance
with the ADA abatement or maintenance of asbestos containing material, and
mitigation for radon) or which the Company otherwise plans or expects to make in
order to cure or remedy any construction, electrical, mechanical or other
defects, to renovate, maintain, rehabilitate or modernize such Company Property,
or otherwise, excluding, however, any tenant improvements required to be made
under any Company Lease. The costs and time schedules for 1997 and subsequent
years set forth in each Capital Expenditure Budget and Schedule are reasonable
estimates and projections. The Capital Expenditure Budget and Schedule for each
Company Property (i) has been established and timely implemented since each
Company Property was acquired by the Company (whether by purchase or as a result
of initial formation transactions), (ii) has a time period of not less than five
years, and (iii) has been provided to Buyer in a true, correct and complete form
as in effect on the date hereof and the amounts set forth


                                       17

<PAGE>

therein represents the good faith business judgment of the Company as to all
known maintenance and capital expenditure items for such Company Property.
Except as set forth in Schedule 3.11(i), there are no outstanding or threatened
requirements by any insurance company which has issued an insurance policy
covering any Company Property, or by any board of fire underwriters or other
body exercising similar functions, requiring any repairs or alterations to be
made to any Company Property.

   (j) Schedule 3.11(j) contains a list of each Company Property, or property
which the Company has under letter of intent or option, which consists of or
includes undeveloped land or which is intended to be or is in the process of
being developed or rehabilitated (collectively, the "Development Properties")
and a brief description of the development or rehabilitation intended by the
Company or any Subsidiary to be carried out or completed thereon (collectively,
the "Projects"), including any budget and development or rehabilitation schedule
therefor prepared by or for the Company or any Subsidiary (collectively, the
"Development Budget and Schedule"). Each Development Property is zoned for the
lawful development thereon of the applicable Project, and the Company or its
Subsidiaries have obtained all permits, licenses, consents and authorizations
required for the lawful development or rehabilitation thereon of such Project.
Except as set forth in Schedule 3.11(j), there are no material impediments to or
constraints on the development or rehabilitation of any Project within the time
frame and for the cost set forth in the Development Budget and Schedule
applicable thereto. In the case of each Project the development of which has
commenced, the costs and expenses incurred in connection with such Project and
the progress thereof are, except as set forth in Schedule 3.11(j), consistent
and in compliance in all material respects with all aspects of the Development
Budget and Schedule applicable thereto. The Company has made available to Buyer
or to its representatives all feasibility studies, soil tests, due diligence
reports and other studies, tests or reports performed by or for the Company, or
otherwise in the possession of the Company, which relate to the Development
Properties or the Projects.

   (k) Except as set forth in Schedule 3.11(k), and except as could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, the Company has disclosed to Buyer all adverse matters known to
the Company with respect to or in connection with the Company Properties and the
HQ Space (including the Company Leases and the Tenancy Leases).

   (l) The leases for the HQ Space and the ground leases underlying the leased
Company Properties referenced in Schedule 3.11(a), if any (collectively, the
"Tenancy Leases"), are accurately described in Schedule 3.11(l). Each of the
Tenancy Leases is valid, binding and in full force and effect as against the
Subsidiary and as against the other party thereto. Except as indicated in
Schedule 3.11(l), none of the Tenancy Leases is subject to any pledge, lien,
sublease, assignment, license or other agreement granting to any third party any
interest therein or any right to the use or occupancy of any premises leased
thereunder. True and complete copies of the Tenancy Leases (including all
amendments, modifications and supplements thereto) will be delivered to Buyer
within five Business Days from the date hereof. Except as set forth in Schedule
3.11(l), there is no pending or threatened proceeding which is reasonably likely
to interfere with the quiet enjoyment of the tenant under any of the Tenancy
Leases. Except as set forth in Schedule 3.11(l), no payments under any Tenancy
Lease are delinquent and no notice of default thereunder has been sent or
received by the Company or any of its Subsidiaries, and there does not exist

requirements, and take all actions and cause its subsidiaries to take all
actions necessary, to maintain its status as a "real estate operating company"
as such term is defined in 29 C.F.R. ss. 2510.3-101. Specifically, but without
limitation, the Company covenants that it has or it will establish an "annual
valuation period", which will be an annual period of no more than 90 days that
will begin no later than the anniversary of the REOC Qualification Date, and
that on at least one day within each annual valuation period, the Company will
maintain the investment of at least 50 percent of its assets (other than
short-term investments pending long-term commitment or distribution to
investors), valued at cost, in real estate which is under active development or
management by the Company as described above. The Company also covenants to
devote substantial resources to the management of the real estate it owns, and
continuously to remain actively engaged in the management or development of real
estate in the ordinary course of its business. The Company agrees to cooperate
with Buyer and to furnish such additional information as may be reasonably
requested by Buyer to evidence the actions indicated above.

Company's Knowledge" (or words of similar import) means actual knowledge of
those individuals identified in Schedule 3.21, and includes any facts, matters
or circumstances set forth in any written notice from any Government Authority
or any other material written notice received by the Company or any Subsidiary,
and also includes any matter of which Buyer informs the Company in writing.

   Section 3.22 "Construction of Material Adverse Effect." For purposes of the
construction of any representation and warranty in this Section 3, and as to the
accuracy thereof, the term "Material Adverse Effect" shall be considered in each
and every event on an aggregate basis with all other representations and
warranties which contain an exception for Material Adverse Effect such that, if
and when one or more of such representations and warranties, considered in the
aggregate, prove to be inaccurate to the extent that an aggregate of $3,000,000
in Loss or Liability is exceeded, then all such representations and warranties
which are subject to exception based on Material Adverse Effect shall, if
inaccurate in any respect, be deemed to be inaccurate without regard to an
exception for Material Adverse Effect and the amount or amounts involved in each
such inaccuracy shall be determined as if no such exception was present.

the ordinary course, and during the period from the date hereof to the date on
which there shall be outstanding no shares of Company Preferred Stock, the
Company will not, except as otherwise consented to or approved by Buyer in
writing or as permitted or required hereby, (i) change or fail to change any
provision of the Company Charter or the Amended Company By-laws in a manner that
would be adverse to Buyer, or (ii) conduct the business of the Company and its
Subsidiaries and engage in transactions except in the ordinary course, except as

   Section 5.5 "No Solicitation of Transactions." Until the Remaining Equity

Partnership of interests in real estate in consideration for Operating
Partnership Units, except for the exercise of outstanding Warrants or stock
options, or the conversion of outstanding Operating Partnership Units.

   Section 5.6 "Information and Access." From the date hereof to the date on
which there shall remain outstanding no Company Preferred Stock, the Company and
its Subsidiaries shall afford to Buyer and Buyer's accountants, counsel and
other representatives full and reasonable access during normal business hours
(and at such other times as the parties may mutually agree) to its properties,
books, contracts, commitments, records and personnel and, during such period,
shall furnish promptly to Buyer (1) a copy of each report, schedule and other
document filed or received by it pursuant to the requirements of the Securities
Laws, and (2) all other information concerning their businesses, personnel and

rights described in this Section, not unduly interfere with the operation of the
businesses of the Company or its Subsidiaries.

   Section 5.7 "Notification of Certain Matters." Until all of the Company
Preferred Stock has been issued or if all of the Company Preferred stock has not
been issued until March 19, 1999, each of Buyer and the Company shall use its
good faith efforts to notify the other party in writing of its discovery of any
matter that would render any of such party's or the other party's
representations and warranties contained herein untrue or incorrect in any
material respect, but the failure of either party to so notify the other party
shall not be deemed a breach of this Agreement.


                                    ARTICLE 6

                          Certain Additional Covenants

   Section 6.1 "Resale." Buyer acknowledges and agrees that the Company
Preferred Stock that Buyer will acquire in any Stock Purchase will not, as of
the relevant Closing thereof, be registered under the Securities Act or the
securities laws of any state and that it may be sold or otherwise disposed of
only in one or more transactions registered under the Securities Act and, where
applicable, such state securities laws or as to which an exemption from the
registration requirements of the Securities Act and, where applicable, such
state securities laws is available.

   Section 6.2 "Use of Funds." The Company shall use the funds received from
Stock Purchases for the repayment of debt (of either the Company or the
Operating Partnership) or for the acquisition, rehabilitation, development or
refinancing by the Company or the Subsidiaries of properties, and for the
payment to Triton Pacific, L.L.C., referred to in the parenthetical in Section
4.5 hereof.

   Section 6.3 "REIT Status." From and after the date hereof, the Company will
elect to be taxed as a REIT in its federal income tax returns, will comply with
all applicable laws, rules and regulations of the Code relating to a REIT, and
will not take any action or fail to take any action which would reasonably be
expected to,


                                       26

<PAGE>

alone or in conjunction with any other factors, result in the loss of its status
as a REIT for federal income tax purposes or the failure of the representations
in Section 3.8 hereof to be true and correct.

   Section 6.4 "Payments." The Company acknowledges and agrees to pay or
reimburse from time to time upon the direction of Buyer, at and after the
Execution Closing, reasonable third-party transaction costs to Buyer, up to an
aggregate amount equal to $300,000, incurred or paid by Buyer and the Advancing
Party in completing this transaction (as invoiced by reasonably detailed
statements or invoices of the nature attached as Schedule 6.4, with appropriate
insertions), as well as with respect to expenses of Buyer and the Advancing
Party incurred or paid in connection with any amendment or modification of, or
waiver of, the transaction documents. It is understood that Buyer will share the
results of its due diligence review, and that of its counsel, with Lehman
Brothers, Inc., as representative of the several underwriters, so as to enable
Lehman Brothers, Inc., to reduce any out-of-pocket expenses it might incur
associated with an anticipated subsequent public offering of Company Common
Stock.

   The Company shall have paid Buyer's expense in an amount equal to $100,000
which shall have been funded into Buyer's bank account as contemplated by the
letter of intent dated as of August 22, 1997. The Company acknowledges and
agrees that, at the Execution Closing, the $100,000 so paid to Buyer shall be
credited towards transaction costs incurred by the Buyer and payable by the
Company. At the Execution Closing, the Company acknowledges and agrees to pay
the amount of $750,000 to Buyer, as a holdback allowance, which Buyer may, at
its option, deduct from the amount of Purchase Price which would otherwise be
payable at the Initial Closing.

   Notwithstanding any termination of this Agreement by Buyer pursuant to
Section 9.1(b) or 9.1(d), the Company acknowledges and agrees to make the
payments as set forth above.

   Section 6.5 "Preemptive Rights." (a) Buyer shall have the rights set forth in
this Section 6.5 as the holder of record and beneficially of shares of Company
Stock. The rights set forth herein are in favor of Buyer and its successors and
assigns, provided that any exercise procedures to be accomplished hereunder
shall be performed by Buyer or its nominee and no other person may accomplish
such procedures or seek to exercise the preemptive right set forth in this
Section 6.5. Absent an express assignment of the rights of Buyer under this
Section 6.5, no transfer by Buyer of shares of Company Preferred Stock or
Company Common Stock shall affect the rights of Buyer hereunder.

   (b) Buyer shall have, at any time and from time to time, the preemptive right
to purchase, in the case of the proposed issuance by the Company of, or the
proposed granting by the Company of shares of, any class of Company Stock, or
any rights to subscribe for or to purchase, or any options for the purchase of,
Company Stock or any stock or securities convertible into or exchangeable for
Company Stock (including, without limitation, interests in the Operating
Partnership) (such rights or options being hereinafter referred to as "Options"
and such convertible or exchangeable stock or securities being hereinafter
referred to as "convertible securities"). Except upon the occurrence on or
before November 31, 1997, of an underwritten widely distributed offering of
Company Common Stock at a price per share to the public of not less than
$11.3125, with not more than $150,000,000 in gross offering proceeds, on each
occasion that the Company proposes to issue Company Stock, options, warrants or
convertible securities, or any of the foregoing, the Company shall give to Buyer
prior written notice (the "Company Notice") of its intention, by first class
mail, postage prepaid, addressed at its last address as shown by the records of
the Company describing the same, the price and the specific terms (or in the
context of an offering of Company Stock, convertible securities, warrants or
options to the public, a range of price and terms) upon which the Company
proposes to issue the same. Buyer shall have 15 Business Days from the date of
the receipt by Buyer of the Company Notice to deliver a notice (the "Rights
Exercise Notice") notifying the Company of Buyer's intention to purchase all or
a part of its pro rata share of shares or other securities represented by
Company Stock, convertible securities, warrants or options, or any of the
foregoing, in accordance herewith, for the price and upon the terms specified by
the Company Notice, such pro rata share to be 19.9% (or, in the event of the
widely distributed public offering on the schedule, at the price and in the
amount of gross offering proceeds noted above, such lesser percentage as Buyer
shall hold immediately after such offering assuming no purchase by Buyer in such


                                       27

<PAGE>

offering or hereunder in connection with such offering) reduced after completion
of the public offering of Company Common Stock by Lehman Bros., Inc. (or such
lesser percentage as may reflect the beneficial ownership of Buyer of such
shares or securities or Company Stock, options, warrants or convertible
securities, warrants or any of the foregoing, but assuming until March 19, 1999,
that Buyer has purchased as at the Execution Closing all 2,737,000 shares of
Company Preferred Stock the sale and purchase of which is the object of this
Agreement, and assuming thereafter that Buyer is the holder of each and every
outstanding share of Company Preferred Stock), and at a price or prices no less
favorable to Buyer than the price or prices at which such Company Stock,
convertible securities, options or warrants are proposed to be offered for sale
to others, less, in the event of any sale other than a public offering, the per
unit amount of any placement fees or commissions, and provided, however, that
the purchase of such Company Stock, convertible securities, warrants or options
shall be consummated prior to the later of (i) 30 days after the date of the
Rights Exercise Notice and (ii) the date that the Company consummates the
issuance of the Company Stock, convertible securities, warrants or options
described in the Company Notice. If, in connection with any proposed issue of
Company Stock, convertible securities, warrants or options, the Buyer fails to
exercise in full its preemptive right as set forth in this Section 6.5, then
subject to the next following sentence, the Company may sell the unsold Company
Stock, convertible securities, warrants or options at any time within 180 days
(60 days in the case of a public offering) thereafter at a price and upon terms
no more favorable to the purchasers thereof than specified in the Company
Notice; provided, that the Company shall not sell or grant, or permit conversion
under, any Company Stock, convertible securities, warrants or Options, or any of
the foregoing, after such 180-day period (or 60-day period in the case of a
public offering) without renewed compliance with this Section 6.5; provided,
further, that in the case of a widely distributed underwritten public offering
of Company Stock, convertible securities, warrants or options, if in the good
faith opinion of the Company and the underwriter, such renewed compliance by the
Company with the procedural requirements hereunder (i.e., timing of notices,
etc.) would otherwise materially impede the consummation of such public
offering, the parties agree to take such further action as may be reasonably
necessary to effectuate such offering while preserving Buyer's substantive
preemptive right hereunder.

   (c) The provisions of this Section 6.5 shall not apply to any shares of any
class of the Company Stock or convertible securities, warrants, options, or any
of them, (i) issuable upon redemption of Operating Partnership Units, the
conversion of any Company Preferred Stock, or upon exercise of the Warrants;
(ii) issuable upon conversion of convertible securities or the exercise of
options or warrants, or both, if Buyer was offered the opportunity to purchase
such shares or securities, or convertible securities, warrants or options, or
both, pursuant to this Section 6.5, and declined the same, or as to which Buyer
was not given such opportunity by reason of the application of this Section 6.5;
(iii) issuable in connection with stock splits, stock dividends or
recapitalizations as to the effects of which adjustment will be made as provided
elsewhere herein, or in the Certificate of Designation pertaining to the Company
Preferred Stock; (iv) issuable to employees and prospective employees, directors
and prospective directors, pursuant to any plan or pattern of employee or
director equity participation set forth in Schedule 3.3(a); and (v) issuable
upon acquisition of assets by the Operating Partnership in consideration for the
issuance of Operating Partnership Units.

   (d) Notwithstanding the foregoing, if and to the extent that Buyer is
prevented or prohibited from the exercise in full or in part of its preemptive
right to purchase any Company Stock, convertible securities, warrants or
options, due to restrictions on the ownership by Buyer (or any group of holders
with which such Buyer may be affiliated or may be deemed to be affiliated) of
any thereof, whether under applicable Delaware law, or the Amended Company
By-laws, or by reason of restrictions applicable for purposes of the Company's
continued qualification as a REIT for purposes of the Code (the "Exercise
Restriction"), such number of Company Stock, convertible securities, warrants or
options required to be purchased pursuant to such preemptive right shall
automatically be reduced to such amount as to not exceed the Exercise
Restriction, and Buyer from time to time thereafter may exercise such right up
to an aggregate number of Company Stock, convertible securities, warrants or
options as is equal to such reduction, subject always to the restrictions as
aforesaid.

   (e) The rights of Buyer set forth in this Section 6.5 shall commence on the
date hereof and shall expire on the fifth anniversary of the date hereof, except
as to purchases as to which Buyer may make on a deferred basis under Section
6.5(d) which shall continue without time restriction.


                                       28

   Section 6.6 "Board of Directors". On or before October 31, 1997, Buyer or any
Affiliate of Buyer designated by Buyer and the Company will have consulted
concerning the election of an additional individual to serve on the Board of
Directors, the Board of Directors will have considered the views and advice of
Buyer or any Affiliate of Buyer designated by Buyer with respect to the
background and experience it is desirable that such an individual possess and as
to specific individuals to be considered for such a position, and an additional

of Buyer designated by Buyer as to any such election or appointment will not be
sought or required. However, except as provided in the Certificate of

firm which on an ongoing basis is rendering professional services to, the

Company, be considered by the Company or elected or appointed as such an

otherwise occur.

   Section 6.7 "Transactions with Affiliates." Except as to matters as set forth
in Schedule 3.9(f) as in effect on the date hereof (but not including any
renewal, extension, amendment, alteration or other continuation of the same

have the right, and the Company, the Operating Partnership and the Subsidiaries
shall be bound by such right, to approve or disapprove in its sole and absolute
discretion any proposed transaction involving Affiliates of the Company,
including but not limited to The Berkshire Group, and Affiliates of The
Berkshire Group, Laurence Gerber, Douglas Krupp, George Krupp, David Marshall,
and any Affiliate of a predecessor organization of The Berkshire Group, or any
of such Persons, but excluding from the prohibition in this Section 6.7
transactions involving Partnership Affiliates. Without having previously secured
in writing such approval of Buyer as to any such transaction, the Company, the
Operating Partnership and the Subsidiaries, or any of such Persons, will not
incur any obligation or liability as to any such transaction, nor make any
announcement thereto.

   Section 6.8 "Company Stock Authorized, Issued and Outstanding." As of the
date seven days after the Initial Closing, Company shall inform Buyer of the
number of shares of Company Stock authorized, issued and outstanding, as of the
date thereof.

                            Survival; Indemnification

   Section 8.1 "Survival." All representations, warranties and (except as
provided by the last sentence of this Section 8.1) covenants and agreements of
the parties contained herein, including indemnity or indemnification agreements
contained herein, or in any Schedule or Exhibit hereto, or any certificate,
document or other instrument delivered in connection herewith shall survive the
Initial Closing until the third anniversary of the final Subsequent Purchase. No
Action or proceeding may be brought with respect to any of the representations
and warranties, or any of the covenants or agreements which survive until the
third anniversary of the final Subsequent Purchase, unless written notice
thereof, setting forth in reasonable detail the claimed misrepresentation or
breach of warranty or breach of covenant or agreement, shall have been delivered
to the party alleged to have breached such representation or warranty or such
covenant or agreement prior to the first anniversary of the Initial Closing.
Those covenants or agreements that contemplate or may involve actions to be

   Section 8.2 "Indemnification by Buyer or the Company." (a) Subject to Section

the Company, its successors and assigns, from and against any and all damages,
claims, losses, expenses, costs, obligations, and liabilities, including
liabilities for all reasonable attorneys' fees and expenses (including attorney
and expert fees and expenses incurred to enforce the terms of this Agreement)
and Liabilities (collectively, "Loss and Expenses") suffered, directly or
indirectly, by the Company by reason of, or arising out of, (i) any breach as of
the date made or deemed made or required to be true of any representation or
warranty made by Buyer in or pursuant to this Agreement, or (ii) any failure by
Buyer to perform or fulfill any of its covenants or agreements set forth herein.
Notwithstanding any other provision of this Agreement to the contrary, in no
event shall Loss and Expenses include a party's incidental or consequential
damages.

   (b) Subject to Section 8.1, from and after any Closing Date, the Company
shall indemnify and hold harmless Buyer, its successors and assigns, from and
against any and all Loss and Expenses, suffered, directly or indirectly, by
Buyer by reason of, or arising out of, (i) any breach as of the date made or
deemed made or required to be true of any representation or warranty made by the
Company in or pursuant to this Agreement and any statements made in any
certificate delivered pursuant to this Agreement, or (ii) any failure by the
Company to perform or fulfill any of its covenants or agreements set forth
herein. Notwithstanding any other provision of this Agreement to the contrary,
in no event shall Loss and Expenses include a party's incidental or
consequential damages.

   Loss and Expenses of Buyer as to which Buyer shall be indemnified by the
Company in accordance with this Section 8.2(b) shall include amounts measured as
provided in the next two following sentences. Any breach or inaccuracy of any
sort referred to in clause (i) of the first sentence of this Section 8.2(b) (any
such, an "Inaccuracy") shall create Loss and Expenses of Buyer in an amount
equal to the product of the Buyer Portion (as defined below) multiplied by the
amount or amounts of (i) any Loss or Expenses of the Company or any Subsidiary


                                       32

<PAGE>

and (ii) any failure to receive, loss of or reduction in revenue of the Company
or any Subsidiary, in either case misstated in or omitted from the Agreement or
any certificate in an Inaccuracy. In all cases, Loss and Expenses of Buyer shall
be adjusted upwards to reflect payment, when made by the Company to Buyer, of
indemnity pursuant to this Section 8.2(b), such that Buyer receives indemnity
from the Company with respect to the Liability represented by any payment to
Buyer pursuant to this Section 8.2(b).

   As used in this Section 8.2(b), "Buyer Portion" shall mean a fraction (i) the
numerator of which is the sum of (A) the number of shares of Company Common
Stock held by Buyer plus (B) the number of shares of Company Common Stock which
Buyer would at any time be entitled to receive on conversion of Company
Preferred Stock purchased by Buyer (at the then applicable Conversion Price, and
otherwise as set forth in and established pursuant to Article FIRST, Section 5
of the Certificate of Designation, and assuming until March 19, 1999, that Buyer
has purchased at the Execution Closing all 2,737,000 shares of Company Preferred
Stock the sale and purchase of which is the object of this Agreement, and
assuming thereafter that Buyer is the holder of each and every outstanding share
of Company Preferred Stock), and (ii) the denominator of which is a number equal
to (A) the number of all shares of Company Common Stock then outstanding or
which would be outstanding after giving effect to rights to receive shares of
Company Common Stock pursuant to the exercise of conversion privileges under
then outstanding, fully paid and non-assessable securities of the Company,
including the Company Preferred Stock, minus (B) the number of shares
established in clause (i) as the numerator of the fraction.

   (c) Notwithstanding the foregoing, (i) neither Buyer nor the Company shall be
responsible for any Loss and Expenses as provided by paragraphs (a) and (b),
respectively, of this Section 8.2, until the cumulative aggregate amount of such
Loss and Expenses suffered by Buyer or the Company, as the case may be, exceeds
$400,000, in which case Buyer or the Company, as the case may be, shall then be
liable for such Loss and Expenses exceeding such amount, and (ii) the cumulative
aggregate indemnity obligation of each of Buyer and the Company under this
Section 8.2 shall in no event exceed the Total Equity Commitment. Except with
respect to third-party claims being defended in good faith or claims for
indemnification with respect to which there exists a good faith dispute, the
indemnifying party shall satisfy its obligations hereunder within 30 days of
receipt of a notice of claim under this Article 8.

   Section 8.3 "Third-Party Claims." If a claim by a third party is made against
an Indemnified Party and if such Indemnified Party intends to seek indemnity
with respect thereto under this Article, such Indemnified Party shall promptly
notify the indemnifying party in writing of such claims setting forth such
claims in reasonable detail. The indemnifying party shall have 20 days after
receipt of such notice to undertake, through counsel of its own choosing and at
its own expense, the settlement or defense thereof, and the Indemnified Party
shall cooperate with it in connection therewith, provided, however, that the
Indemnified Party may participate in such settlement or defense through counsel
chosen by such Indemnified Party, provided that the fees and expenses of such
counsel shall be borne by such Indemnified Party. The Indemnified Party shall
not pay or settle any claim which the indemnifying party is contesting.
Notwithstanding the foregoing, the Indemnified Party shall have the right to pay
or settle any such claim, provided that in such event it shall waive any right
to indemnity therefor by the indemnifying party. If the indemnifying party does
not notify the Indemnified Party within 20 days after the receipt of the
Indemnified Party's notice of a claim of indemnity hereunder that it elects to
undertake the defense thereof, the Indemnified Party shall have the right to
contest, settle or compromise the claim but shall not thereby waive any right to
indemnity therefor pursuant to this Agreement.

termination of this Agreement by either or both of the Company and Buyer

(Expenses), 10.2 (Governing Law), and 10.4 (Notices) shall survive the
termination of this Agreement; provided, however, that such termination shall
not relieve any party hereto of any liability for any breach of this Agreement.

   Section 9.3 "Expenses." Except as set forth in this Agreement, whether or not
any Stock Purchase is consummated, all legal and other costs and expenses
incurred in connection with this Agreement and the transactions contemplated

Agreement unless otherwise stated.

   Section 10.7 "Amendments and Waivers." This Agreement may not be modified or
amended except by an instrument or instruments in writing signed by the party
against whom enforcement of any such modification or amendment is sought. Either
party hereto may, only by an instrument in writing, waive compliance by the
other party hereto with any term or provision hereof on the part of such other
party hereto to be performed or complied with. The waiver by any party hereto of
a breach of any term or provision hereof shall not be construed as a waiver of
any subsequent breach.

   Section 10.8 "Interpretation; Absence of Presumption." (a) For the purposes
hereof, (i) words in the singular shall be held to include the plural and vice
versa and words of one gender shall be held to include the other gender as the
context requires, (ii) the terms "hereof," "herein," and "herewith" and words of
similar import shall, unless otherwise stated, be construed to refer to this
Agreement as a whole (including all of the Schedules and Exhibits hereto) and
not to any particular provision of this Agreement, and Article, Section,
paragraph, Exhibit and Schedule references are to the Articles, Sections,
paragraphs, Exhibits and Schedules to this Agreement unless otherwise specified,

hereof.

that, in view of the uniqueness of the parties hereto, the parties hereto would
not have an adequate remedy at law for money damages in the event that this
Agreement were not performed in accordance with its terms, and therefore agree
that the parties hereto shall be entitled to specific enforcement of the terms
hereof in addition to any other remedy to which the parties hereto may be
entitled at law or in equity.

   Section 10.12 "Schedules." Any matter set forth on any Schedule shall be
deemed to be referred to on all other Schedules to which such matter logically

   Capitalized terms which are used in this Agreement and which are not defined

ascribed to them in the Stock Purchase Agreement.

   Section 2. Shelf Registration. (a) Obligation to File and Maintain. At
any time following the purchase by Buyer of Company Preferred Stock, promptly
upon the written request of Buyer, the Company will use its best efforts to file
with the Commission a registration statement under the Securities Act for the
offering on a continuous or delayed basis in the future of all of the
Registrable Securities (the "Shelf Registration"). The Shelf Registration shall
be on an appropriate form and the Shelf Registration and any form of prospectus
included therein or prospectus supplement relating thereto shall reflect such
plan of distribution or method of sale as Buyer may from time to time notify the
Company, including the sale of some or all of the Registrable Securities in a
public offering or, if requested by Buyer, subject to receipt by the Company of
such information (including information relating to purchasers) as the Company
reasonably may require, (i) in a transaction constituting an offering outside
the United States which is exempt from the registration requirements of the
Securities Act in which the Company undertakes to effect registration of such
shares as soon as possible after the completion of such offering in order to
permit such shares to be freely tradeable in the United States, (ii) in a
transaction constituting a private placement under Section 4(2) of the
Securities Act in connection with which the Company undertakes to register such
shares after the conclusion of such placement to permit such shares to be freely
tradeable by the purchasers thereof, or (iii) in a transaction under Rule 144A
of the Securities Act in connection with which the Company undertakes to
register such shares after the conclusion of such transaction to permit such
shares to be freely tradeable by the purchasers thereof. The Company shall use
its best efforts to keep the Shelf Registration continuously effective for the
period beginning on the date on which the Shelf Registration is declared
effective and ending on the first date that there are no Registrable Securities
(provided that the Company may terminate the effectiveness of a Shelf
Registration on the second anniversary of the date of effectiveness thereof plus
a number of days equal to the number of days in all Registration Suspension
Periods relating to such Shelf Registration). During the period during which the
Shelf Registration is effective, the Company shall supplement or make amendments
to the Shelf Registration, if required by the Securities Act or if reasonably
requested by Buyer or an underwriter of Registrable Securities, including to
reflect any specific plan of distribution or method of sale, and shall use its
reasonable best efforts to have such supplements and amendments declared
effective, if required, as soon as practicable after filing.

   (b) Black-Out Periods of Buyer. Notwithstanding anything herein to the
contrary, (i) the Company shall have the right, by written notice to Buyer (the
"Suspension Notice"), exercisable on not more than two occasions during any
three-year period, from time to time to require Buyer not to sell under the
Shelf Registration or to suspend the effectiveness thereof during the period
starting with the date 30 days prior to the Company's good faith estimate, as
certified in writing by an executive officer of the Company to Buyer, of the
proposed date of filing of a registration statement or a preliminary prospectus
supplement relating to an existing shelf registration statement, in either case,
pertaining to an underwritten public offering of equity securities of the
Company for the account of the Company, and ending on the date 90 days following
the effective date of such registration statement or the date of filing of such
prospectus supplement, and (ii) the Company shall be entitled to postpone or
suspend (but not for a period exceeding 90 days) the filing or effectiveness of
a registration statement otherwise required to be prepared and filed by it
pursuant to this Section 2 if the Company determines, in its good faith
judgment, that such registration and offering or continued effectiveness would
interfere with any material financing, acquisition, disposition, corporate
reorganization or other material transaction involving the Company or any of its
subsidiaries or public disclosure thereof would be required prior to the time
such disclosure might otherwise be required, or when the Company is in
possession of material information that it deems advisable not to disclose in a
registration statement (either, the "Registration Suspension Period").

   (c) Black-Out Periods of the Company. Subject to the conditions of this
Section 2(c), Buyer shall have the right, exercisable on not more than two
occasions during any three-year period, from time to time to require the Company
not to sell any common equity securities of the Company or any securities
convertible into 


                                       3

<PAGE>

common equity securities of the Company under any registration statement or
prospectus supplement relating to an existing shelf registration statement
(other than sales of shares of Common Stock upon the redemption of Operating
Partnership Units,or limited partnership units of any other Subsidiary of the
Company and sales of equity securities issued or granted pursuant to any
employee benefit or similar plan or any dividend reinvestment plan), or to
suspend the effectiveness thereof, during the period starting with the date 30
days prior to Buyer's good faith estimate, as certified in writing by an
executive officer of Buyer to the Company, of a proposed date of filing of a
preliminary prospectus supplement relating to a Shelf Registration filed
pursuant to Section 2(a), pertaining to an underwritten public offering of
Registrable Securities, and ending on the date 60 days following the date of
filing the final prospectus supplement, but in no event on a date later than 75
days following the date of filing of the preliminary prospectus supplement. In
no event may the Company include in any preliminary prospectus supplement under
which Buyer is offering Registrable Securities covered by this Section 2(c) any
equity securities of the Company or any securities convertible into equity
securities of the Company.

   (d) Shelf Registrations. The Company shall be obligated to effect and
maintain in effect a Shelf Registration under this Section 2. A Shelf
Registration shall not be deemed to have been effected, unless such registration
becomes effective pursuant to the Securities Act and is kept continuously
effective of a period of at least two years (other than any periods during such
period of effectiveness which are Registration Suspension Periods, and provided
that no such Registration Suspension Periods shall count towards such two-year
period); provided, however, that no Shelf Registration shall be deemed to have
been effected if such registration cannot be used by Buyer for more than 45 days
as a result of any stop order, injunction or other order of the Commission or
other Government Authority for any reason other than an act or omission of
Buyer.

   (e) Notice. The Company shall give Buyer prompt notice in the event that the
Company has suspended sales of Registrable Securities under Section 2(b).

   (f) Expenses. All Company Registration Expenses incurred in connection with
any Shelf Registration which may be requested under this Section 2 shall be
borne by the Company, and all Registration Expenses incurred in connection with
any such Shelf Registration shall be borne by Buyer.

   (g) Selection of Underwriters. Any and all underwriters or other agents
involved in any sale of Registrable Securities pursuant to a registration
statement contemplated by this Section 2 shall include such underwriter(s) or
other agent(s) as selected by Buyer and are assented to by the Company with such
assent not to be unreasonably withheld or delayed.

   (h) Company Right to Purchase. If Buyer proposes to offer any Registrable
Securities in an underwritten offering under a Shelf Registration statement
filed by the Company pursuant to Section 2(a), Buyer shall give the Company
prior written notice of the proposed offering, setting forth the number of
Registrable Securities that Buyer proposes to offer, the expected timing of the
proposed offering, and the expected gross selling price of such offering. The
Company shall have the right, if it irrevocably so notifies Buyer within 10
Business Days after its receipt of Buyer's notice, to purchase all of the
Registrable Securities that Buyer proposes to offer, at the gross selling price
set forth in Buyer's notice to the Company. In the event the Company shall so
notify Buyer, it shall effect such purchase within 10 Business Days.

   Section 3. Requested Registration. (a) Obligation to File. If, with respect
to Registerable Securities at any time, and from time to time thereafter, the
Company shall receive from Buyer a written request for the Company to effect any
registration, qualification or compliance with respect to Registerable
Securities, then, at a time specified in such request, the Company will use
reasonable efforts to effect all such registrations, qualifications and
compliances when so specified in such request, subject as aforesaid and provided
that the Company shall have at least 85 days after such request (including,
without limitation, the execution of an undertaking to file post-effective
amendments, appropriate qualification under the applicable blue sky or other
state 


                                       4

securities laws and appropriate compliance with regulations issued under
the Securities Act and any other governmental requirements or regulations) to
effect all such registrations, qualifications and compliances as would permit or
facilitate the sale and distribution of Registerable Securities as are specified
in such request; provided that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 3:

        (i) in a particular jurisdiction in which the Company would be required
to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the Securities
Act; or

        (ii) if the Company has already effected one registration for Buyer
pursuant to this Section 3 during the immediately preceding twelve-month period
or if there is a registration effective pursuant to Section 2 at the time of
such request.

   (b) Underwriting. If Buyer intends to distribute the Registerable Securities
covered by its request by means of an underwritten public offering, it shall so
advise the Company. Any and all underwriters or other agents involved in any
sale of Registrable Securities pursuant to a registration statement contemplated
by this Section 3 shall include such underwriter(s) or other agent(s) as
selected by Buyer and are assented to Buyer, with such assent not to be
unreasonably withheld or delayed.

   (c) Black-Out Periods of Buyer. Subject to the conditions of this Section 3,
(i) the Company shall have the right, exercisable on not more than two occasions
during any three-year period, from time to time to require Buyer not to sell
under the registration requested pursuant to this Article 3 or to suspend the
effectiveness thereof during the period starting with the date 30 days prior to
the Company's good faith estimate, as certified in writing by an executive
officer of the Company to Buyer, of the proposed date of filing of a
registration statement or a preliminary prospectus supplement relating to an
existing registration statement, in either case, pertaining to an underwritten
public offering of equity securities of the Company for the account of the
Company, and ending on the date 90 days following the effective date of such
registration statement or the date of filing of such prospectus supplement, and
(ii) the Company shall be entitled to postpone or suspend (but not for a period
exceeding 90 days) the filing or effectiveness of a registration statement
otherwise required to be prepared and filed by it pursuant to this Article 3 if
the Company determines, in its good faith judgment, that such registration and
offering or continued effectiveness would interfere with any material financing,
acquisition, disposition, corporate reorganization or other material transaction
involving the Company or any of its subsidiaries or public disclosure thereof
would be required prior to the time such disclosure might otherwise be required,
or when the Company is in possession of material information that it deems
advisable not to disclose in a registration statement.

   (d) Black-Out Periods of the Company. Subject to the conditions of this
Section 3.4, Buyer shall have the right, exercisable on not more than two
occasions from time to time, to require the Company not to sell any common
equity securities of the Company or any securities convertible into common
equity securities of the Company under any registration statement or prospectus
supplement relating to an existing registration statement requested pursuant to
this Article 3 (other than sales of shares of Common Stock upon the redemption
of Operating Partnership Units, or limited partnership units of any other
Subsidiary of the Company and sales of equity securities issued or granted
pursuant to any employee benefit or similar plan or any dividend reinvestment
plan), or to suspend the effectiveness thereof, during the period starting with
the date 15 days prior to Buyer's good faith estimate, as certified in writing
by an executive officer of Buyer to the Company, of a proposed date of filing of
a preliminary prospectus supplement relating to a registration statement filed
pursuant to Section 3.1, pertaining to an underwritten public offering of
Registrable Securities, and ending on the date 60 days following the date of
filing the final prospectus supplement, but in no event on a date later than 75
days following the date of filing of the preliminary prospectus supplement.


                                       5

   (e) Expenses. All Company Registration Expenses incurred in connection with
any registration which may be requested under this Section 3 shall be borne by
the Company, and all Registration Expenses incurred in connection with any such
registration shall be borne by Buyer.

   Section 4. Incidental Registrations. (a) Notification and Inclusion. If the
Company proposes to register for its own account any common equity securities of
the Company or any securities convertible into common equity securities of the
Company under the Securities Act (other than (i) a registration relating solely
to the sale of securities to participants in a dividend reinvestment plan, (ii)
a registration on Form S-4 relating to a business combination or similar
transaction permitted to be registered on such Form S-4, (iii) a registration on
Form S-8 relating solely to the sale of securities to participants in a stock or
employee benefit plan, (iv) a registration permitted under Rule 462 under the
Securities Act registering additional securities of the same class as were
included in an earlier registration statement for the same offering and declared
effective, (v) a registration on Form S-3 for Company Common Stock issuable upon
conversion of Operating Partnership Units issued in exchange for assets or (vi)
the Public Offering), the Company shall, at each such time, promptly give
written notice of such registration to Buyer. Upon the written request of Buyer
given within 10 days after receipt of such notice by Buyer, the Company shall
seek to include in such proposed registration such Registrable Securities as
Buyer shall request be so included and shall use its best efforts to cause a
registration statement covering all of the Registrable Securities that Buyer has
requested to be registered to become effective under the Securities Act,
provided, that for purposes of this Section 4 Registrable Securities of Buyer
shall be limited to Company Common Stock. The Company shall be under no
obligation to complete any offering of securities it proposes to make under this
Section 3 and shall incur no liability to Buyer for its failure to do so. If, at
any time after giving written notice of its intention to register any securities
and prior to the effective date of the registration statement filed in
connection with such registration, the Company shall determine for any reason
not to register or to delay registration of such securities, the Company may, at
its election, give written notice of such determination to Buyer and, thereupon,
(i) in the case of a determination not to register, the Company shall be
relieved of its obligation to register any Registrable Securities in connection
with such registration (but not from its obligation to pay the Registration
Expenses incurred in connection therewith) and (ii) in the case of a
determination to delay registering, the Company shall be permitted to delay
registering any Registrable Securities for the same period as the delay in
registering such other securities. The Company agrees, for the benefit of Buyer,
not to grant or afford to any holder of Operating Partnership Units (or holder
of shares of Company Common Stock issuable upon exercise of Operating
Partnership Units) referred to in clause (v) of the parenthetical to the first
sentence of this clause (a), any "piggyback" or incidental registration rights
that would arise from or become effective upon the registration by the Company
on behalf of Buyer of any Registrable Securities.

   (b) Cut-back Provisions. If a registration pursuant to this Section 4
involves an Underwritten/Placed Offering of the securities so being registered,
whether or not solely for sale for the account of the Company, which securities
are to be distributed by or through one or more underwriters of recognized
standing under underwriting terms customary for such transaction, and the
underwriter or the managing underwriter, as the case may be, of such
Underwritten/Placed Offering shall inform the Company of its belief that the
amount of securities requested to be included in such registration or offering
exceeds the amount which can be sold in (or during the time of) such offering
without delaying or jeopardizing the success of the offering (including the
price per share of the securities to be sold), then the Company will include in
such registration (i) first, all the securities of the Company which the Company
proposes to sell for its own account and (ii) second, to the extent of the
amount which the Company is so advised can be sold in (or during the time of)
such offering, Registrable Securities requested to be included in such
registration, pro rata, among Buyer and others exercising incidental
registration rights, on the basis of shares of Company Common Stock requested to
be included by all such persons.

   (c) Expenses. The Company shall bear and pay all Company Registration
Expenses incurred in connection with any registration of Registrable Securities
pursuant to this Section 4 for Buyer, and all Registration Expenses incurred in
connection with any registration of any other securities referred to in the
first sentence of 


                                       6

<PAGE>

Section 4(a), and Buyer shall bear and pay all Registration Expenses incurred in
connection with any registration of Registrable Securities pursuant to this
Section 4, other than Company Registration Expenses, for Buyer.

   (d) Duration of Effectiveness. At the request of Buyer, the Company shall,
subject to Section 2(b), use its best efforts to keep any registration statement
for which Registrable Securities are included under this Section 4 effective and
usable for up to 90 days (subject to extension for the length of any
Registration Suspension Period), unless the distribution of securities
registered thereunder has been earlier completed; provided, however, that in no
event will the Company be required to prepare or file audited financial
statements with respect to any fiscal year by a date prior to the date on which
the Company would be so required to prepare and file such audited financial
statements if such registration statement were no longer effective and usable.

   Section 5. Registration Procedures. In connection with the filing of any
registration statement as provided in Section 2, 3 or 4, the Company shall use
its best efforts to, as expeditiously as reasonably practicable:

      (a) prepare and file with the Commission the requisite registration
   statement (including a prospectus therein) to effect such' registration and
   use its best efforts to cause such registration statement to become
   effective, provided that before filing such registration statement or any
   amendments or supplements thereto, the Company will furnish to the counsel
   selected by Buyer copies of all such documents proposed to be filed, which
   documents will be subject to the review of such counsel before any such
   filing is made, and the Company will comply with any reasonable request made
   by such counsel to make changes in any information contained in such
   documents relating to Buyer;

      (b) prepare and file with the Commission such amendments and supplements
   to such registration statement and the prospectus used in connection
   therewith as may be necessary to maintain the effectiveness of such
   registration and to comply with the provisions of the Securities Act with
   respect to the disposition of all securities covered by such registration
   statement until, in the case of Section 2, the termination of the period dur
   ing which the Shelf Registration is required to be kept effective, or, in the
   case of Section 3 or Section 4, the earlier of such time as all of such
   securities have been disposed of and the date which is 90 days after the date
   of initial effectiveness of such registration statement;

      (c) furnish to Buyer such number of conformed copies of such registration
   statement and of each such amendment and supplement thereto (in each case
   including all exhibits), such number of copies of the pro spectus contained
   in such registration statements (including each complete prospectus and any
   summary prospectus) and any other prospectus filed under Rule 424 under the
   Securities Act, in conformity with the requirements of the Securities Act,
   and such other documents, including documents incorporated by reference, as
   Buyer may reasonably request;

      (d) register or qualify all Registrable Securities under such other
   securities or blue sky laws of such jurisdictions as Buyer shall reasonably
   request, to keep such registration or qualification in effect for so long as
   such registration statement remains in effect, and take any other action
   which may be reasonably necessary or advisable to enable Buyer to consummate
   the disposition in such jurisdictions of the securities owned by Buyer,
   except that the Company shall not for any such purpose be required to qualify
   generally to do business as a foreign corporation in any jurisdiction wherein
   it would not but for the requirements of this paragraph be obligated to be so
   qualified, or to consent to general service of process in any such
   jurisdiction, or to subject the Company to any material tax in any such
   jurisdiction where it is not then so subject;


                                       7

<PAGE>

      (e) cause all Registrable Securities covered by such registration
   statement to be registered with or approved by such other Government
   Authority as may be reasonably necessary to enable Buyer to consummate the
   disposition of such Registrable Securities;

      (f) furnish to Buyer a signed counterpart, addressed to Buyer (and the
   underwriters), of

         (i) an opinion of counsel for the Company, dated the effective date of
      such registration statement (and, if such registration includes an
      underwritten public offering, dated the date of the closing under the
      underwriting agreement), reasonably satisfactory in form and substance to
      Buyer, and

         (ii) to the extent permitted by then applicable rules of professional
      conduct, a "comfort" letter, dated the effective date of such registration
      statement (and, if such registration includes an underwritten public
      offering, dated the date of the closing under the underwriting agreement),
      signed by the independent public accountants who have certified the
      Company's financial statements included in such registration statement;

   covering substantially the same matters with respect to such registration
   statement (and the prospectus included therein) and, in the case of the
   accountants' letter, with respect to events subsequent to the date of such
   financial statements, all as are customarily covered in opinions of issuer's
   counsel and in accountants' letters delivered to the underwriters in
   underwritten public offerings of securities;

      (g) immediately notify Buyer at any time when the Company becomes aware
   that a prospectus relating thereto 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 registration statement, as then in effect,
   includes 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 not misleading in the light of the circumstances under
   which they were made, and at the request of Buyer promptly prepare and
   furnish to Buyer a reasonable number of copies of a supplement to or an
   amendment of such prospectus as may be necessary so that, as thereafter
   delivered to the purchasers of such securities, such prospectus shall not
   include an untrue statement of a material fact or omit to state a material
   fact required to be stated therein or necessary to make the statements
   therein not misleading in the light of the circumstances under which they
   were made;

      (h) comply or continue to comply in all material respects with the
   Securities Act and the Exchange Act and with all applicable rules and
   regulations of the Commission, and make available to its security holders, as
   soon as reasonably practicable, an earnings statement covering the period of
   at least 12 months, but not more than 18 months, beginning with the first
   full calendar month after the effective date of such registration statement,
   which earnings statement shall satisfy the provisions of Section 11(a) of the
   Securities Act, and not file any amendment or supplement to such registration
   statement or prospectus to which Buyer shall have reasonably objected on the
   grounds that such amendment or supplement does not comply in all material
   respects with the requirements of the Securities Act, having been furnished
   with a copy thereof at least five Business Days prior to the filing thereof;

         (i) provide a transfer agent and registrar for all Registrable
      Securities covered by such registration statement not later than the
      effective date of such registration statement; and

         (ii) list all Company Stock covered by such registration statement on
      any securities exchange on which any of the Company Stock is then listed.

Buyer shall furnish in writing to the Company such information regarding Buyer
(and any of its affiliates), the Registrable Securities to be sold, the intended
method of distribution of such Registrable Securities, and such other


                                       8

<PAGE>

information requested by the Company as is necessary for inclusion in the
registration statement relating to such offering pursuant to the Securities Act
and the rules of the Commission thereunder. Such writing shall expressly state
that it is being furnished to the Company for use in the preparation of a
registration statement, preliminary prospectus, supplementary prospectus, final
prospectus or amendment or supplement thereto, as the case may be.

   Buyer agrees by acquisition of the Registrable Securities that upon receipt
of any notice from the Company of the happening of any event of the kind
described in paragraph (g) of this Section 5, Buyer will forthwith discontinue
its disposition of Registrable Securities pursuant to the registration statement
relating to such Registrable Securities until Buyer's receipt of the copies of
the supplemented or amended prospectus contemplated by paragraph (g) of this
Section 5.

   Section 6. Underwritten Offerings. If requested by the underwriters for any
underwritten offerings by Buyer, under a registration requested pursuant to
Section 2(a) or Section 3(a), the Company and the Operating Partnership will
enter into a customary underwriting agreement with such underwriters for such
offering, to contain such representations and warranties by the Company and the
Operating Partnership and such other terms as are customarily contained in
agreements of this type, including indemnities to the effect and to the extent
provided in Section 9. Buyer shall be a party to such underwriting agreement and
may, at its option, require that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to the obligations of Buyer. Buyer shall not be required to make any
representations or warranties to or agreement with the Company or the
underwriters other than representations, warranties or agreements regarding
Buyer and Buyer's intended method of distribution and any other representation
or warranty required by law.

   Section 7. Preparation, Reasonable Investigation. In connection with the
preparation and filing of the registration statement under the Securities Act
pursuant to Section 2 or 3 hereof, the Company will give Buyer, its
underwriters, if any, and their respective counsel, the opportunity to
participate in the preparation of such registration statement, each prospectus
included therein or filed with the Commission, and each amendment thereof or
supplement thereto, and will give each of them such access to its books and
records and such opportunities to discuss the business of the Company with its
officers, its counsel and the independent public accountants who have certified
its financial statements as shall be necessary, in the opinion of Buyer's and
such underwriters' respective counsel, to conduct a reasonable investigation
within the meaning of the Securities Act.

   Section 8. Tag-Along Rights. Buyer shall be entitled to the rights set forth
in this Section 8.

   (a) Rights and Notice. The Company shall not directly or indirectly sell or
otherwise dispose of shares of Company Stock to any person (a "Third Party") in
connection with an Extraordinary Transaction in which the consideration for some
or all of the shares of Company Stock is cash or cash equivalents (as determined
under GAAP), unless the terms and conditions of such sale or other disposition
shall include an offer to Buyer to include, at the option of Buyer, in such sale
or other disposition of the Company Stock owned by Buyer at the time of such
sale or other disposition determined in accordance with Section 8(b) (the
"Tag-Along Shares"). The Company shall send a written notice (the "Tag-Along
Notice") to Buyer setting forth the number of shares of Company Stock proposed
to be sold or otherwise disposed of in the Extraordinary Transaction (the
"Extraordinary Transaction Shares"), and the price at which such shares are
proposed to be sold (or the method by which such price is proposed to be
determined). At any time within 15 days after its receipt of the Tag-Along
Notice, Buyer may exercise its option to sell the Tag-Along Shares by furnishing
written notice of such exercise (the "Exercise Notice") to the Company.

   (b) Number of Shares to be Included. If the proposed sale or other
disposition by the Company in connection with an Extraordinary Transaction is
consummated, Buyer shall have the right to sell to the Third Party as part of
such proposed sale or other disposition of such number of Company Stock (with
Company


                                       9

<PAGE>

Preferred Stock determined in terms of the number of shares of Company Common
Stock into which it would then be entitled to be converted without giving effect
to any time restriction on conversion) owned by Buyer equal to the product of
(i) the ratio (which in no event shall exceed 20% for purposes of this Section
8) of the total number of shares of Company Stock owned by Buyer at the time
that Buyer receives the Tag-Along Notice to the total number of outstanding
shares of Company Stock at the time that Buyer receives the Tag-Along Notice,
and (ii) the number of Extraordinary Transaction Shares; provided, however, that
if the number of Tag-Along Shares is less than the number of shares of Company
Stock owned by Buyer at the time that Buyer receives the Tag-Along Notice, such
that the number of shares that Buyer would have been able to sell as determined
above in this Section 8(b) based upon the total number of shares of Company
Stock owned by Buyer at the time Buyer receives the Tag-Along Notice is more,
then Buyer shall have the right to sell to the Third Party as part of the
proposed sale or other disposition to the Third Party by the Company in
connection with an Extraordinary Transaction such larger number of shares as
determined based upon the total number of shares of Company Stock owned by Buyer
at the time that Buyer receives the Tag-Along Notice. All calculations pursuant
to this paragraph shall exclude and ignore any unissued shares of Company Stock
issuable pursuant to stock options, warrants and other rights to acquire shares
of Company Stock and pursuant to convertible or exchangeable securities other
than with respect to the Company Stock held by Buyer, but shall include shares
of Company Common Stock issuable upon redemption of limited partnership
interests in the Operating Partnership (all of which shares shall be deemed to
be outstanding for purposes of this calculation).

   (c) Abandonment of Sale. Each of the Company and the Third party shall have
the right, in its sole discretion, at all times prior to consummation of the
proposed sale or other disposition giving rise to the tag-along right granted by
this Section 8 to abandon, rescind, annul, withdraw or otherwise terminate such
sale or other disposition, whereupon all tag-along rights in respect of such
sale or other disposition pursuant to this Section 8 shall become null and void,
and neither the Company nor the Third Party shall have any liability or
obligation to Buyer with respect thereto by virtue of such abandonment,
rescission, annulment, withdrawal or termination.

   (d) Terms of Sale. The purchase from Buyer pursuant to this Section 8 shall
be on the same terms and conditions, including the per share price and the date
of sale or other disposition, as are applicable to the Company, and which shall
be consistent with the relevant Tag-Along Notice.

   (e) Timing of Sale. If, with respect to any Tag-Along Notice, Buyer fails to
deliver an Exercise Notice within the requisite time period, the Company shall
have 150 days after the expiration of the time in which the Exercise Notice is
required to be delivered in which to sell or otherwise dispose of not more than
the number of shares of Company Stock described in the Tag-Along Notice on terms
not more favorable to the Company than were set forth in the Tag-Along Notice.
If, at the end of 150 days following the receipt of the Tag-Along Notice, the
Company has not completed the sale or other disposition of Company Stock in
accordance with the terms described in the Tag-Along Notice, the Company shall
again be obligated to comply with the provisions of this Section 8 with respect
to, and provide Buyer with the opportunity to participate in, any proposed sale
or other disposition of shares of Company Stock in connection with an
Extraordinary Transaction.

   Section 9. Indemnification. (a) Indemnification by the Company. In the event
of any registration of any Registrable Securities of the Company under the
Securities Act, the Company will, and hereby does, indemnify and hold harmless
Buyer, each other person who participates as an underwriter in the offering or
sale of such securities and each other person who controls any such underwriter
within the meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which Buyer or any such underwriter or
controlling person may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the registration statement under which such
Registrable Securities were registered under the Securities Act, any preliminary
prospectus, final prospectus or summary prospectus contained therein, or any
amendment or supplement


                                       10

<PAGE>

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
light of the circumstances under which they were made, not misleading, and the
Company will reimburse Buyer and each such underwriter and controlling person
for any reasonable legal or any other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, liability,
action or proceedings; provided, however, that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability (or
action or proceeding in respect thereof) or expense arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in such regis tration statement, any such preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by Buyer or
any other person who participates as an underwriter in the offering or sale of
such securities, in either case, specifically stating that it is for use in the
preparation thereof, and provided, further, that the Company shall not be liable
to any person who participates as an underwriter in the offering or sale of
Registrable Securities or any other person, if any, who controls such
underwriter within the meaning of the Securities Act in any such case to the
extent that any such loss, claim, damage, liability (or action or proceeding in
respect thereof) or expense arises out of such person's failure to send or give
a copy of the final prospectus or supplement to the persons asserting an untrue
statement or alleged untrue statement or omission or alleged omission at or
prior to the written confirmation of the sale of Registrable Securities to such
person if such statement or omission was corrected in such final prospectus or
supplement. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of Buyer or any such underwriter or
controlling person and shall survive the transfer of such securities by Buyer.

   (b) Indemnification by Buyer. In the event of registration of any Registrable
Securities in any registration statement pursuant to Section 2, Section 3 or
Section 4, the Company shall receive an undertaking satisfactory to it from
Buyer to indemnify and hold harmless (in the same manner and to the same extent
as set forth in paragraph (a) of this Section 9) the Company, each director of
the Company, each officer of the Company and each other person, if any, who
controls the Company within the meaning of the Securities Act, and each other
person who participates as an underwriter in the offering or sale of such
securities and each other person who controls any such underwriter within the
meaning of the Securities Act, with respect to any untrue statement or alleged
untrue statement of a material fact in or omission or alleged omission to state
a material fact from such registration statement, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, if such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by Buyer specifically stating that
it is for use in the preparation of such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Company or any such director, officer, or
controlling person and shall survive the transfer of such securities by Buyer.

   (c) Notices of Claims, etc. Promptly after receipt by an indemnified party of
notice of the commencement of any action or proceeding involving a claim
referred to in the preceding paragraphs of this Section 9, such indemnified
party will, if a claim in respect thereof is to be made against an indemnifying
party, give written notice to the latter of the commencement of such action;
provided, however, that the failure of any indemnified party to give notice as
provided herein shall not relieve the indemnifying party of its obligations
under the preceding paragraphs of this Section 9, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist in respect of such claim, the
indemnifying party shall be entitled to participate in and to assume the defense
thereof, jointly with any other indemnifying party similarly notified to the
extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to the indemnified party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation.


                                       11

   (d) Other Indemnification. Indemnification similar to that specified in the
preceding paragraphs of this Section 9 (with appropriate modifications) shall be
given by the Company and Buyer with respect to any required registration or
other qualification of securities under any federal or state law or regulation
of Governmental Authority other than the Securities Act.

   (e) Indemnification Payments. The indemnification required by this Section 9
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.

   (f) Contribution. If, for any reason, the foregoing indemnity is unavailable,
or is insufficient to hold harmless an indemnified party, then the indemnifying
party shall contribute to the amount paid or payable by the indemnified party as
a result of the expense, loss, damage or liability, (i) in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and the indemnified party on the other (determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or omission relates to information supplied by the indemnifying party or the
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission), or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law or provides a lesser sum to the indemnified party
than the amount hereinafter calculated, in the proportion as is appropriate to
reflect not only the relative fault of the indemnifying party and the
indemnified party, but also the relative benefits received by the indemnifying
party on the one hand and the indemnified party on the other, as well as any
other relevant equitable considerations. No indemnified party guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any indemnifying party
who was not guilty of such fraudulent misrepresentation.

   Section 10. Covenants Relating to Rule 144, etc. The Company will file in a
timely manner, information, documents and reports in compliance with the
Exchange Act and will, at its expense, forthwith upon the request of Buyer,
deliver to Buyer a certificate, signed by the Company's principal financial
officer, stating (a) the Company's name, address and telephone number (including
area code), (b) the Company's Internal Revenue Service identification number,
(c) the Company's Commission file number, (d) the number of shares of Company
Common Stock and the number of shares of Company Preferred Stock outstanding as
shown by the most recent report or statement published by the Company, and (e)
whether the Company has filed the reports required to be filed under the
Exchange Act for a period of at least 90 days prior to the date of such
certificate and in addition has filed the most recent annual report required to
be filed thereunder. If at any time the Company is not required to file reports
in compliance with either Section 13 or Section 15(d) of the Exchange Act, the
Company will, at its expense, forthwith upon the written request of Buyer, make
available adequate current public information with respect to the Company within
the meaning of paragraph (c)(2) of Rule 144 of the General Rules and Regulations
promulgated under the Securities Act.

   The Company agrees that if Buyer arranges for the delivery to the Company of
an opinion of counsel (reasonably satisfactory to the Company), to the effect
that the Registrable Securities may be sold in a transaction exempt from the
registration and prospectus delivery requirements of the Securities Act so that
all transfer restrictions and legends with respect thereto (other than those
required by the Company Charter in effect on the date hereof) are removed upon
the consummation of such sale, Buyer may request that its certificates
evidencing such Registrable Securities be exchanged by the Company for
certificates free and clear of all transfer restrictions and legends (other than
those required by the Company Charter in effect on the date hereof, unless
deleted from the Company Charter after the date hereof and before any such
delivery). The Company agrees to deliver such legend free shares certificates to
Buyer within three business days of Buyer's request therefor. Should the Company
fail to deliver such certificates within such three business day period, the
Company agrees to indemnify Buyer for all losses sustained by Buyer as a result
of any decrease in value of such Registrable Securities 


                                       12

<PAGE>

from such date beginning on the fourth business day following Buyer's request
for exchange and continuing until such date as new certificates, free and clear
of all legends, has been delivered to Buyer.

   Section 11. Miscellaneous. (a) Counterparts. This Agreement may be executed
in one or more counterparts, all of which shall be considered one and the same
agreement, and shall become effective when one or more counterparts have been

transmission service shall be considered original executed counterparts for

Registrable Securities.
