                                  COMMON STOCK
 
    * THIS PROSPECTUS EXCLUDES 579,089 SHARES OF COMMON STOCK AND SHARES
UNDERLYING 225,201 OPERATING PARTNERSHIP UNITS SOLD BY BCP TO THE COMPANY'S
FOUNDERS, ALAN M. LEVENTHAL AND LIONEL P. FORTIN, IN CONNECTION WITH THE
FORMATION OF THE COMPANY AND THE CLOSING OF THE ORIGINAL OFFERING.
 
   
    This Prospectus relates to the Common Stock, par value $.01 per share (the
"Common Stock"), of Beacon Capital Partners, Inc., a Maryland corporation
("BCP") formed on January 21, 1998 as a Massachusetts corporation and
reorganized as a Maryland corporation on March 17, 1998. The Common Stock was
issued and sold (the "Original Offering") on March 20, 1998 (the "Closing
Date"), April 3, 1998 (the "Second Closing Date"), and April 13, 1998 (the
"Final Original Offering Closing Date") to the Initial Purchaser (as defined
herein) and was simultaneously resold by the Initial Purchaser in transactions
exempt from the registration requirements of the Securities Act of 1933, as
amended (the "Securities Act"), to persons reasonably believed by the initial
purchaser to be Qualified Institutional Buyers as defined in Rule 144A under the
Securities Act, to a limited number of institutional "Accredited Investors" and
to certain individual "Accredited Investors" (as defined under the Securities
Act). No shares of the Company's Common Stock are being sold by the Company
hereby.
    
 
   
    The Common Stock offered hereby (the "Offered Securities") may be offered
and sold from time to time by the purchasers in the Original Offering named
herein or their transferees, pledgees, donees or successors (collectively, the
"Selling Stockholders") pursuant to this Prospectus. The Offered Securities may
be sold by the Selling Stockholders from time to time directly to purchasers or
through agents, underwriters or dealers. See "Selling Stockholders" and "Plan of
Distribution." If required, the names of any such agents or underwriters
involved in the sale of the Offered Securities and the applicable agent's
commission, dealer's purchase price or underwriter's discount, if any, will be
set forth in an accompanying supplement to this Prospectus (the "Prospectus
Supplement"). The Selling Stockholders will receive all of the net proceeds from
the sale of the Offered Securities and will pay all underwriting discounts,
selling commissions and transfer taxes, if any, applicable to any such sale. The
Company is responsible for payment of all other expenses incident to the
registration of the Offered Securities. The Selling Stockholders and any
broker-dealers, agents or underwriters that participate in the distribution of
the Offered Securities may be deemed to be "Underwriters" within the meaning of
the Securities Act, and any commission received by them and any profit on the
resale of the Offered Securities purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act.
    
 
   
    BCP is a Maryland corporation established to conduct real estate investment
and development activities. The day-to-day operations of BCP and its operating
partnership, Beacon Capital Partners, L.P. (the "Operating Partnership," and
collectively with BCP, the "Company") are managed internally by the senior
management of BCP. BCP is the sole general partner of the Operating Partnership,
through which the investments of the Company are made.
    
 
   
    SEE "RISK FACTORS" BEGINNING ON PAGE 10 FOR MATERIAL RISK FACTORS RELEVANT
TO AN INVESTMENT IN THE COMMON STOCK INCLUDING, AMONG OTHERS:
    
 
    - The Company relies upon, and its success is dependent upon, key personnel
      of BCP, including Alan M. Leventhal and Lionel P. Fortin.
 
   
    - It may be difficult for the Company to effectively implement its
      acquisition strategy and manage the resulting growth of the Company.
    
 
   
    - The Company has a limited operating history and no established sources of
      financing.
    
 
   
    - Certain of the Company's investments, such as the development of real
      estate assets, will require significant management resources, will be
      illiquid, and may decrease in value because of changes in economic
      conditions.
    
 
   
    - There is currently no market for the Company's Common Stock and there can
      be no assurance that any such market will develop.
    
 
    - Management of the Company may earn substantial compensation from the
      Long-Term Incentive Plan (as defined below) which, if paid, could
      substantially reduce cash available for distribution to stockholders.
 
   
    - Conflicts of interest may arise between the Company's stockholders and
      management in connection with the Company's management incentive plans.
    
 
   
    - The Company is subject to competition from numerous competitors, including
      other real estate investment trusts ("REITs") and private real estate
      opportunity funds which may affect the Company's ability to effectively
      implement its acquisition strategy.
    
 
   
    - The Company intends to leverage the Company's assets, and may, under the
      Company's current guidelines, borrow up to 60% of its total market
      capitalization, which can compound losses. The Company's organizational
      documents contain no limits on leverage of the Company's assets.
    
 
   
    - The Company's capital stock is subject to certain ownership limitations
      designed to ensure the Company's compliance with the REIT qualification
      requirements, which could inhibit a change in control of the Company.
    
 
    - BCP may be subject to income tax at regular corporate rates if it fails to
      qualify as a REIT, which would substantially reduce the amount of cash
      available for distribution to stockholders.
 
    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON
THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
IS A CRIMINAL OFFENSE.
 
              THE DATE OF THIS PROSPECTUS IS              , 1998.

                                OFFERING SUMMARY
 
    THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS SUBJECT TO, AND
QUALIFIED IN ITS ENTIRETY BY, THE MORE DETAILED INFORMATION INCLUDED ELSEWHERE
IN THIS PROSPECTUS. UNLESS THE CONTEXT REQUIRES OTHERWISE, ALL REFERENCES IN
THIS PROSPECTUS TO THE "COMPANY" SHALL MEAN BCP AND THE OPERATING PARTNERSHIP.
 
THE COMPANY
 
   
    BCP is a recently-organized Maryland corporation, formed on January 21, 1998
as a Massachusetts corporation and reincorporated, through a merger, in Maryland
on March 17, 1998, which intends to qualify as a real estate investment trust (a
"REIT"). BCP was established to conduct real estate investment and development
activities. The Company presently owns 25 operating properties, consisting of 42
buildings and approximately 3.3 million rentable square feet. In addition,
through a joint venture, the Company holds a 12-acre site for development. The
day-to-day operations of BCP and the Operating Partnership are managed
internally by the senior management of BCP. BCP is the sole general partner of
the Operating Partnership. The Company believes that it has developed an
organization of investment and investment management professionals that is
well-positioned to take advantage of today's real estate and capital markets
environment.
    
 
   
    The Company's management combines real estate, capital markets and corporate
expertise, which the Company believes will uniquely position it to capitalize on
market and industry trends in complex real estate-related transactions across
product, geographic and industry lines. Eight of the nine senior managers of the
Company have an average of over 20 years experience in the real estate business.
See "The Company--Directors and Executive Officers" and "Investment Strategies
and Experience."
    
 
INVESTMENT STRATEGY
 
   
    BCP's investment strategy (the "Investment Strategy") is driven by
management's experience with public and private real estate companies. As the
capitalization of the real estate industry continues to evolve toward a
publicly-held format, BCP believes, based upon its management's experience
through several economic cycles in the real estate industry, that numerous
investment opportunities will continue to emerge that reflect several primary
shifts in the real estate industry. These shifts include:
    
 
    - rapid recovery of the real estate markets
 
    - extraordinary growth of the public capital markets for real estate
      companies
 
    - continued consolidation of the ownership of real estate
 
    - alignment of interests between investors and management
 
    - recognition of real estate companies as operating businesses
 
   
    These factors have resulted in significant investment opportunities in real
estate, including arbitrage between public and private market pricing. It is
BCP's belief that as the real estate industry continues its transformation (and
recognizing that real estate is still fundamentally a cyclical business),
disparities in pricing and capital availability, as well as ineffective
management of real estate assets by others, will provide opportunities for
skilled and experienced management teams such as the Company's management team.
Initially, the Company expects to focus primarily on opportunities in the office
sector. As the real estate market cycle advances, the Company expects additional
opportunities to emerge in non-office market sectors, including opportunities in
the hotel, residential and industrial sectors. See "Risk Factors-- Investment
Activity Risks--Multi-Sector Investment Strategy." Increasingly, management
expertise and creative real estate solutions will be required for successful
real estate companies. BCP's management team has a proven track record in this
regard in office as well as other property types. Based on these observations,
BCP intends to identify, create and realize value for the Company in its
investment in several principal areas of the real estate market (as outlined
below).
    
 
                                       1
<PAGE>
   
    The Company's strategy is to profitably purchase, develop and manage real
estate. BCP will implement this strategy through its senior management's
experience managing both public and private real estate companies. Eight of the
nine senior managers of the Company have an average of over 20 years experience
in the real estate industry. During this time, management has developed an
ability to identify and capitalize on industry trends. Management will apply
these skills to capitalize on opportunities that emerge as the real estate
industry continues its transformation and maturation process. The Company's
management has also developed an informal network of domestic and foreign
institutional relationships in the real estate industry. Management will attempt
to utilize these relationships to help identify opportunities to implement its
strategy.
    
 
   
    The Company's investments are expected to target the following principal
real estate areas listed below (the "Real Estate-Related Assets"), although the
Company cannot anticipate with any certainty the percentage of its investments
that will be made in each category.
    
 
   
    - VALUE-ADDED REPOSITIONINGS AND DISCOUNTED PURCHASES--repositioning and
      recapitalization of under-utilized or poorly capitalized real property
      through purchases of debt on such properties, including investments in
      mortgage loans at a discount to the face value of such debt, or purchases
      of equity in such properties at a discount to the replacement cost of such
      properties;
    
 
    - DEVELOPMENT AND RE-DEVELOPMENT--strategic ground-up development or
      re-development of existing properties that can benefit from repositioning;
 
    - MULTIPLE PROPERTY PORTFOLIOS--acquisition of portfolios of real property
      owned by financial institutions, corporations and other non-strategic
      owners of real estate, as well as liquidating closed-end commingled funds
      and other large holders of real estate portfolios;
 
    - JOINT VENTURES AND STRATEGIC PARTNERSHIPS--formation of, or acquisition of
      interests in, joint ventures or strategic partnerships as a way to
      leverage both capital and management expertise; and
 
    - REAL ESTATE COMPANIES AND REAL ESTATE-RELATED BUSINESSES--investment in
      companies primarily engaged in the business of real estate ownership, real
      estate services or other real estate intensive operating businesses as
      well as related companies that serve the changing needs of the real estate
      industry.
 
   
    In addition to investments in Real Estate-Related Assets, the Company may
also invest in other areas related to the real estate industry which it believes
may add value to the Company (the "Other Assets", and together with Real
Estate-Related Assets, "Assets"). The Company believes that it will have
distinct advantages over other real estate investment companies because the
Company's senior management team has extensive experience in the acquisition,
development, financing, management and disposition of Assets. Furthermore, as
the capitalization of the real estate industry continues to evolve toward a
publicly-held format, BCP's management believes that its prior success in
managing a publicly-held REIT will provide the Company with an additional
competitive advantage over other privately-held REITs and real estate investment
funds.
    
 
ADVANTAGES OF THE COMPANY STRUCTURE
 
   
    The Company believes that by managing its day-to-day operations internally,
the Company will offer competitive advantages to its stockholders in comparison
to externally managed REITs as a result of the alignment of interests between
management and stockholders. The Company also believes that it has a competitive
advantage over certain other real estate investment entities, such as entities
which are not qualified REITs, due to its ability to use Units of the Operating
Partnership as acquisition currency for potential acquisitions that may provide
sellers of property with certain tax advantages. See "Federal Income Tax
Considerations."
    
 
                                       2
<PAGE>
THE BCP SISTER CORP.
 
   
    The Company anticipates that, although it has no immediate plans for such
investment, it may, from time to time, identify Assets which it believes may be
advantageous investments but which may be inappropriate (including for REIT
qualification or other tax reasons) for investment, in whole or in part, by the
Company. In order to permit stockholders to participate in the economic benefits
that may be associated with such non-qualifying REIT Assets, the Company
intends, from time to time, to utilize a structure (employed by certain other
REITs) often referred to as a "paper clip." This "paper clip" structure would
involve distributing to BCP's stockholders the equity interests of a
newly-organized sister company (each, a "BCP Sister Corp."), that would not
elect to qualify as a REIT, to make investments in certain non-qualifying REIT
Assets. At the present time, no BCP Sister Corp. has been formed, nor does the
Company have any current plans to form a BCP Sister Corp.
    
 
   
    The BCP Sister Corp. is intended to function primarily as an operating
company, in contrast to the Company's principal focus on investment as a REIT in
the Real Estate-Related Assets. The Company's ability to fully utilize the BCP
Sister Corp. structure could be adversely affected as a result of future
legislation. See "Risk Factors--Legal and Tax Risks--Tax Risks."
    
 
   
SUMMARY RISK FACTORS
    
 
    An investment in the Common Stock involves various risks, and prospective
investors should consider carefully the matters discussed under "Risk Factors"
prior to an investment in the Company. Such risks include, among others, the
following:
 
    - The Company will rely upon, and its success is dependent upon, key
      personnel of BCP, including Alan M. Leventhal and Lionel P. Fortin.
 
   
    - It may be difficult for the Company to effectively implement its
      acquisition strategy and manage the resulting growth in the Company.
    
 
   
    - The Company has a limited operating history and no established sources of
      financing.
    
 
   
    - Certain of the Company's investments, such as the development of real
      estate assets, will require significant management resources, will be
      illiquid, and may decrease in value because of changes in economic
      conditions.
    
 
   
    - There is currently no market for the Company's Common Stock and there can
      be no assurance that any such market will develop.
    
 
    - Management of the Company may earn substantial compensation from the
      Long-Term Incentive Plan which, if paid, could substantially reduce cash
      available for distribution to stockholders.
 
   
    - Conflicts of interest may arise between the Company's stockholders and
      management in connection with the Company's management incentive plans.
    
 
   
    - The Company is subject to competition from numerous competitors, including
      other REITs and private real estate opportunity funds which may affect the
      Company's ability to effectively implement its acquisition strategy.
    
 
   
    - The Company intends to leverage the Company's assets, and may, under the
      Company's current guidelines, borrow up to 60% of its total market
      capitalization, which can compound losses. The Company's organizational
      documents contain no limits on leverage of the Company's assets.
    
 
   
    - The Company's capital stock is subject to certain ownership limitations
      designed to ensure the Company's compliance with the REIT qualification
      requirements, which could inhibit a change of control of the Company.
    
 
    - BCP may be subject to income tax at regular corporate rates if it fails to
      qualify as a REIT, which would substantially reduce the amount of cash
      available for distribution to stockholders.

                        RECENT AND PENDING ACQUISITIONS
    
 
   
RECENT ACQUISITIONS
    
 
   
    THE ATHENAEUM PORTFOLIO.  On May 1, 1998 the Company purchased a portfolio
of eleven buildings in Cambridge, MA known as The Athenaeum Portfolio. The
mixed-use portfolio consists of approximately 970,000 square feet and contains
office, laboratory and retail uses as well as a 1,530 space parking garage. The
purchase price for the portfolio was $195 million, including the assumption of
approximately $69 million of first mortgage debt. The Company estimates that the
aggregate purchase price is approximately 80% of replacement cost. On May 20,
1998, the Company completed the formation of a joint venture with PW
Acquisitions IX, LLC, an affiliate of PaineWebber, in which both parties hold a
50% interest in the master limited liability company that controls the two
limited liability companies that hold title to The Athenaeum Portfolio. Under
the terms of the joint venture agreement, the PaineWebber affiliate will
reimburse the Company for 50% of all costs associated with the acquisition of
The Athenaeum Portfolio in exchange for its 50% interest in the master limited
liability company.
    
 
    The portfolio is comprised of two components: One Kendall Square and The
Athenaeum House (215 First Street), which are located within close proximity of
the Massachusetts Institute of Technology ("M.I.T."). Several of the buildings
were originally built as manufacturing buildings at the turn of the century and
were fully renovated in the mid-1980's for office and laboratory uses. A
nine-screen cinema was added to the complex in 1994. The buildings are currently
100% occupied. Major tenants which occupy more than 10% of the portfolio
include: Genzyme, CLAM Associates, Cambridge Neuroscience, and Mitotix.
 
   
    The Athenaeum Portfolio is located in the East Cambridge office market. The
overall Cambridge office market includes approximately 10 million square feet.
According to Spaulding & Slye, the Cambridge office market had an overall
vacancy rate of 2.4% as of June 30, 1998.
    
 
   
    TECHNOLOGY SQUARE & THE DRAPER BUILDING.  On June 24, 1998 the Company
purchased a four-building complex known as Technology Square and an adjacent
building known as The Draper Building from a partnership managed by The
Prudential Insurance Company of America ("Prudential"). The properties are
located in Cambridge, MA, adjacent to One Kendall Square (described above) and
M.I.T. and consist of 1,026,000 square feet. The purchase price for the
properties was $123 million. As part of the purchase, Prudential accepted
approximately $51.4 million in the form of units of the Operating Partnership at
a blended rate of $20.31 per unit. There are no mortgages outstanding against
these properties.
    
 
   
    Technology Square is currently 100% leased to two tenants: M.I.T. and
Polaroid Corporation. The leases with these tenants expire in mid-1999. Average
net lease rates in place are $6.53 per square foot, which the Company believes
to be substantially below current market. Accordingly, the Company believes it
will be able to re-let Technology Square at current market rents. The Company
intends to re-develop and re-lease the property over the next 18-24 months and
projects substantial increases in net operating income as the property is
stabilized at current market net rents, which the Company believes to be
approximately $24 per square foot. The scope of the re-development is currently
under review by the Company and, therefore, the estimated cost has not yet been
established. It is anticipated by management that any such redevelopment would
be financed by the Company from cash on hand or project financing. The Draper
Building is 100% leased to Draper Labs on a long-term lease which expires on
October 20, 2001. The lease contains extension options through October 2051,
pursuant to which the tenant has an option, under certain circumstances, to
acquire The Draper Building.
    
 
   
    Technology Square and The Draper Building are located in the East Cambridge
office market. The overall Cambridge office market includes approximately 10
million square feet. Upon completion of this acquisition, the Company will own
approximately 2 million square feet of office and commercial space in the
Cambridge market, including both The Athenaeum Portfolio and Technology Square
and The Draper

Building. According to Spaulding & Slye, the Cambridge office market had an
overall vacancy rate of 2.4% as of June 30, 1998.
    
 
   
    THE BREUNIG PORTFOLIO  On July 1, 1998 the Company acquired a 1,335,000
square foot portfolio of seven office properties and seven research &
development (R&D) properties located in suburban Dallas, TX. The properties were
purchased from Breunig Commercial Management, Inc., a Dallas-based real estate
owner and manager for a total consideration of $91.2 million, including the
assumption of approximately $21.8 million of first mortgage debt. The purchase
price is approximately $68 per square foot, which the Company estimates to be
approximately 65% of the replacement cost of the assets.
    
 
   
    The properties are predominately located along the North Central Expressway
corridor in North Dallas. As measured on a square foot basis, the portfolio is
approximately two-thirds office (842,000 s.f.), and one-third R&D (493,000
s.f.). The current average occupancy rate for the portfolio is 95%. However,
nearly 54% of the space in the buildings is expiring over the next three years,
providing an opportunity to substantially increase the net operating income as
the properties are re-leased at current market rents. Average net rents at the
properties are more than $3.00/s.f. (or nearly 56%) below what the Company
estimates to be current market rents. Major tenants include: Blue Cross, Texas
Instruments, Dallas Teachers Credit, Puretan, Inc., and Specialized Resources.
    
 
   
    The overall Dallas office market contains 133 million square feet of space.
According to Cushman & Wakefield, as of the end of the Second Quarter of 1998,
the overall vacancy rate was 13.1%. The office properties in The Breunig
Portfolio are located primarily in the North Central Expressway and LBJ Freeway
submarkets where the Second Quarter vacancy rates were 11.9% and 5.5%,
respectively.
    
 
   
    The Office/Showroom category of the Dallas Industrial market (which includes
R&D space), contains 49.5 million square feet of space. The overall vacancy rate
as of the end of the Second Quarter was 5.4%. The R&D properties in The Breunig
Portfolio are located primarily in the Richardson/Plano and North Dallas
submarkets, where the Second Quarter 1998 vacancy rates were 3.4% and 3.5%,
respectively.
    
 
   
PENDING ACQUISITION
    
 
   
    SUNNYVALE DEVELOPMENT.  On August 9, 1998, the Company entered into a joint
venture agreement with Mathilda Partners LLC, an affiliate of Menlo Equities, a
California based developer, by which the Company has agreed to fund 87.5% of the
equity required to develop two Class A office buildings and Mathilda Partners
LLC has agreed to fund 12.5% of such equity. After each party receives a 12% per
annum return on their equity, the profits from the venture will be split
equally. The venture is under contract to acquire a twelve-acre site on Mathilda
Avenue in Sunnyvale, California, on which the venture plans to construct two
four-story office buildings with surface parking. Although it is anticipated
that the buildings will contain approximately 267,000 square feet, certain
changes in the entitlements for the property will be required to increase the
permitted density from the currently permitted 187,000 square feet. Neither
building has been pre-leased. In addition to funding approximately 40% of the
development expenditures (including the acquisition of the land) from cash
contributions, the venture intends to finance the balance of those expenditures
with a construction loan from an institutional lender. At this point in time,
the scope of the development budget has not been finalized, but it is
anticipated to be approximately $57.0 million if the full 267,000 square feet
are constructed. The site for the development is in the Sunnyvale office
research and development market, which includes approximately 21.5 million
square feet. According to Colliers Parrish International, the Sunnyvale office
market had an overall vacancy rate of 4.2% as of May 1, 1998.
    
 
   
                         MANAGEMENT AND INCENTIVE PLANS
    
 
    The business and investment affairs of the Company are internally managed.
Messrs. Leventhal and Fortin are the founders of the Company and serve as
executive officers and Directors of BCP. The Company believes that it has
developed an organization of real estate investment and investment
 
                                       5
<PAGE>
   
management professionals that is well-positioned to take advantage of today's
real estate and capital markets environment. The Company's professionals combine
real estate, capital markets, and corporate expertise that the Company believes
will uniquely position it to assist the Company in capitalizing on market and
industry trends in complex investments in Real Estate-Related Assets across
product, geographic and industry lines. There can be no assurance, however, that
the experience of such individuals will result in attractive investments for the
Company. See "The Company--Directors and Executive Officers."
    
 
   
    Messrs. Leventhal and Fortin have formed Beacon Capital Participation Plan,
L.P., a Delaware limited partnership ("Beacon Capital Participation Plan") and
have offered equity interests in Beacon Capital Participation Plan to certain
members of the Company's senior management. In addition, Messrs. Leventhal and
Fortin, individually and through Beacon Capital Participation Plan, have
purchased, directly from the Company and the Operating Partnership, a
combination of shares of Common Stock and Units for an aggregate purchase price
of $15 million, representing approximately 3.2% of the equity interests in the
Company on a fully diluted basis. The Company has established a long-term
incentive plan (the "Long-Term Incentive Plan") to align the interests of
management with the interests of the Company's stockholders. Under the Long-Term
Incentive Plan, Beacon Capital Participation Plan has been issued, for no
additional consideration, a Convertible Unit of the Operating Partnership. See
"The Company--Long-Term Incentive Plan" and "Risk Factors--Economic and Business
Risks--Conflicts of Interest." BCP's senior management, by holding equity
interests in Beacon Capital Participation Plan, will be able to participate in
the Long-Term Incentive Plan subject to certain vesting restrictions. See "The
Company-- Long-Term Incentive Plan" and "Risk Factors--Economic and Business
Risks--Conflicts of Interest." As further incentive to the Company's management,
the Company has adopted a stock option and incentive plan (the "Stock Incentive
Plan") whereby a number of the Company's employees will be eligible to receive
options to acquire shares of Common Stock. See "The Company--Management
Compensation" and "--Stock Incentive Plan." There can be no assurance that the
Long-Term Incentive Plan or the Stock Incentive Plan will provide an incentive
to the management of the Company to enhance the value of the Common Stock or
whether the value of the Common Stock will increase at all. See "The Company--
Certain Relationships; Conflicts of Interest" and "Risk Factors--Economic and
Business Risks--Conflicts of Interest."
    
 
                       RESTRICTIONS ON OWNERSHIP OF STOCK
 
   
    Due to limitations on the concentration of ownership of a REIT imposed by
the Internal Revenue Code of 1986, as amended (the "Code"), and to otherwise
address concerns relating to the concentration of stock ownership, the charter
of BCP, as may be amended from time to time (the "Charter") prohibits any single
stockholder from owning, directly or by virtue of the attribution provisions of
the Code or the Exchange Act, more than 9.8% of the aggregate value of the
issued and outstanding shares of Common Stock of BCP (the "Aggregate Stock
Ownership Limit"). Additionally, the Charter provides that certain mutual funds
and certain other widely-held entities (other than pension plans as described in
Section 401(a) of the Code) may actually and beneficially own up to 15% of the
outstanding shares of Common Stock (the "Look-Through Ownership Limit"). The
Board of Directors may waive or modify the Aggregate Stock Ownership Limit and
the Look-Through Ownership Limit with respect to one or more persons if it is
satisfied, based upon the receipt of a ruling from the Internal Revenue Service
(the "Service") or the advice of tax counsel, that ownership in excess of this
limit will not jeopardize the Company's status as a REIT for federal income tax
purposes and will not cause the Company to be a "pension-held" REIT for federal
income tax purposes. See "Description of Securities."

                                USE OF PROCEEDS
 
   
    The Selling Stockholders will receive all of the proceeds from the sale of
the Offered Securities offered hereby. The Company will not receive any of the
proceeds from the sale by the Selling Stockholders of the Offered Securities.
The proceeds from the Company's Original Offering are being used to fund
acquisitions and for operating expenses.
    
 
                              DISTRIBUTION POLICY
 
    The Operating Partnership intends to make distributions to its partners,
including BCP. BCP intends to make distributions to its stockholders of all or
substantially all of its net taxable income each year (subject to certain
adjustments) so as to qualify for the tax benefits accorded to REITs under the
Code. See "Federal Income Tax Considerations--Requirements for Qualification."
 
   
    The declaration and payment of dividends by any BCP Sister Corp. (if and
when formed) will be a business decision to be made by the BCP Sister Corp.'s
board of directors from time to time based on such considerations as the BCP
Sister Corp.'s board of directors deems relevant, will be payable only out of
funds legally available therefor under the law of the state of the BCP Sister
Corp.'s formation and will be subject to any limitations which may be contained
in any applicable debt instruments of the BCP Sister Corp. See "Risk
Factors--Economic and Business Risks--Conflicts of Interest."
    
 
   
    As further incentive to the Company's management, the Company has adopted a
stock option and incentive plan (the "Stock Incentive Plan") whereby a number of
the Company's employees will be eligible to receive options to acquire shares of
Common Stock.

                           TAX STATUS OF THE COMPANY
 
   
    BCP will elect to be taxed as a REIT under Sections 856 through 860 of the
Code, commencing with its taxable year ending December 31, 1998. If BCP
qualifies for taxation as a REIT, BCP generally will not be subject to federal
corporate income tax on its taxable income that is distributed to its
stockholders. A REIT is subject to a number of organizational and operational
requirements, including a requirement that it currently distribute at least 95%
of its annual taxable income. Although BCP does not intend to request a ruling
from the Internal Revenue Service (the "Service") as to its REIT status, BCP has
received, in connection with the filing of this Registration Statement, an
opinion of Goodwin, Procter & Hoar LLP that BCP has been and will be organized
in conformity with the requirements for qualification as a REIT, and that the
proposed manner of operations of BCP will enable it to qualify as a REIT, which
opinion is based on certain factual and other assumptions and representations
with respect to BCP's past and expected ongoing businesses and investment
activities and other customary matters. No assurance can be given as to the
accuracy of such assumptions and representations or that BCP will be able to
comply with them in the future. Furthermore, such opinion is not binding on the
Service or on any court, and no assurance can be given that BCP will operate in
a manner so as to qualify or remain qualified as a REIT. Failure to qualify as a
REIT would render BCP subject to federal income tax (including any applicable
alternative minimum tax) on its taxable income at regular corporate rates and
distributions to BCP's stockholders would not be deductible by BCP. Even if BCP
qualifies for taxation as a REIT, the Company may be subject to certain federal,
state and local taxes on its income and property. In accordance with the REIT
provisions of the Code, BCP will adopt the calendar year as its taxable year. In
connection with BCP's election to be taxed as a REIT, BCP's Charter imposes
restrictions on the transfer of the Common Stock. See "Risk Factors-- Legal and
Tax Risks--Tax Risks" and "Federal Income Tax Considerations--Taxation of the
Company."

    The relationship among BCP, the Operating Partnership, Beacon Capital
Partcipation Plan and the BCP Sister Corp. (if formed), and the equity ownership
thereof is depicted in the picture shown below.
    
 
   
     [Chart describing the relationship of BCP, the Operating Partnership,
  Other Limited Partners, Beacon Capital Participation Plan, BCP Sister Corp.
          and the BCP Sister Corp. Operating Partnership (if formed)]
    
 
- ------------------------
 
(1) The Company anticipates that at the time of formation of the BCP Sister
    Corp., the stockholders of BCP and the BCP Sister Corp. would be the same.
    However, the equity interests of BCP and the BCP Sister Corp. may be owned
    and transferred separately and independently of each other and,
    consequently, the stockholder constituency of each entity may change over
    time.

                                  RISK FACTORS
 
   
    An investment in the Common Stock involves a high degree of risk. Before
purchasing any of the shares of Common Stock offered hereby, prospective
investors should carefully consider the following material risk factors, in
addition to the information set forth elsewhere in this Prospectus.
    
 
                          ECONOMIC AND BUSINESS RISKS
 
   
    DEPENDENCE ON KEY PERSONNEL.  The Company believes that its success will
depend to a significant extent upon the experience of its founders, Alan M.
Leventhal and Lionel P. Fortin, and on other members of senior management of the
Company whose continued service is not guaranteed. The Company believes that
Messrs. Leventhal and Fortin, in particular, have national reputations in the
real estate investment industry which are expected to assist the Company in
identifying Assets for acquisition. Messrs. Leventhal and Fortin have entered
employment and non-competition agreements with the Company, but there can be no
guarantee that these agreements can be judicially enforced. The loss of the
services of either Mr. Leventhal or Mr. Fortin could have a material adverse
effect on the operations of the Company because the Company would have a
diminished capacity to obtain real estate investment opportunities, to
capitalize upon their relationships in the real estate industry and to structure
and execute its potential investments. The Company may not be able to
successfully recruit additional personnel and any additional personnel that are
recruited may not have the requisite skills, knowledge or experience necessary
or desirable to enhance the incumbent management. The Company does not currently
intend to maintain key-man life insurance with respect to any of its executive
officers. See "The Company--Directors and Executive Officers" and "The
Company--Management Compensation."
    
 
   
GROWTH STRATEGY MAY NOT BE SUCCESSFULLY IMPLEMENTED.
    
 
   
    AVAILABILITY OF CAPITAL.  The ability of the Company to implement its growth
strategy depends on access to capital necessary to invest in Assets through the
use of borrowings, subsequent issuances of Common Stock or other securities or
operating cash flow. The Company was formed on January 21, 1998, has a limited
operating history and, other than the proceeds of the Original Offering, has no
established sources of financing. The failure to obtain necessary capital could
have a material adverse effect on the Company's ability to acquire Assets. The
Company anticipates that it will, in part, be dependent upon a bank or other
institutional lender with respect to a credit facility. No such credit facility
has yet been obtained by the Company.
    
 
   
    FAILURE TO EFFECTIVELY MANAGE RAPID GROWTH.  To successfully implement its
acquisition strategy, the Company must integrate acquired Assets into its
existing operations. As a result, the consolidation of functions and integration
of departments, systems and procedures of acquired Assets with the Company's
then-existing operations presents a significant management challenge, and the
failure to effectively integrate such Assets into the Company's management and
operating structures could have a material adverse effect on the results of
operations and financial condition of the Company.
    
 
    PORTFOLIO ACQUISITION RISKS.  The Company's business and acquisition
strategy includes acquisitions of multiple Assets in single transactions in
order to reduce acquisition expenses per property and to enable the Company to
gain a critical mass of Assets that provides operating leverage. However,
portfolio acquisitions are more complex than single-property acquisitions, and
the risk that a multiple-property acquisition will not close may be greater than
in a single-property acquisition. In addition, the Company's costs for a
portfolio acquisition that does not close are generally greater than for a
single-property acquisition that does not close. If the Company fails to close
portfolio acquisitions, its ability to increase its Funds from Operations will
be limited and a charge to earnings for costs related to the failed acquisition
may occur. Portfolio acquisitions may also result in the Company owning Assets
in geographically dispersed markets that are geographically removed from the
Company's principal markets. This geographic diversity will place additional
demands on the Company's ability to manage such operations.
 
                                       10
<PAGE>
Another risk associated with portfolio acquisitions is that a seller may require
that a group of properties be purchased as a package, even though one or more of
the properties in the portfolio does not meet the Company's investment criteria.
In such cases, the Company may attempt to make a joint bid with another buyer,
or the Company may purchase a portfolio of Assets with the intent to
subsequently dispose of those Assets which do not meet its criteria. In the case
of joint bids, however, it is possible that the other buyer may default in its
obligations, which increases the risk that the acquisition may not close, with
the adverse consequences described above. In cases where the Company intends to
dispose of Assets it does not wish to own, there can be no assurance as to how
quickly the Company could sell or exchange such Assets or the terms on which
they could be sold or exchanged.
 
   
    DEVELOPMENT OR REDEVELOPMENT OF ASSETS.  The Company also intends to pursue
the development and construction of Real-Estate Related Assets, in accordance
with the Company's development and underwriting policies in effect from time to
time as opportunities arise. Risks associated with such development and
construction activities include the risk that: (i) the Company may abandon
development opportunities after expending resources to determine feasibility;
(ii) construction costs of a project may exceed original estimates; (iii)
occupancy rates and rents at a newly completed property may not be sufficient to
make the property profitable; (iv) financing may not be available on favorable
terms for development of a property; and (v) construction and lease-up may not
be completed on schedule, resulting in increased debt service expense and
construction costs. Development activities are also subject to risks relating to
the inability to obtain, or delays in obtaining, all necessary zoning, land-use,
building, occupancy, and other required governmental permits and authorizations.
In addition, new development activities, regardless of whether or not they are
ultimately successful, typically require a substantial portion of management's
time and attention.
    
 
    The Company anticipates that development may be financed, in whole or in
part, through equity or debt offerings or under lines of credit or other forms
of secured or unsecured construction financing that will result in the risk
that, upon completion of construction, permanent financing for newly developed
properties may not be available or may be available only on disadvantageous
terms. If a project is unsuccessful, the Company's losses may exceed its
investment in the project.
 
CONFLICTS OF INTEREST.
 
   
    CONFLICTS RELATING TO THE OPERATING PARTNERSHIP.  BCP, as the General
Partner of the Operating Partnership, will have fiduciary obligations to the
limited partners (including Beacon Capital Participation Plan) of the Operating
Partnership, which may conflict with the interests of BCP's stockholders. In
addition, those persons holding Units, as limited partners, will have the right
to vote as a class on certain amendments to the Operating Partnership Agreement
and individually to approve certain amendments that would adversely affect their
rights, which voting rights may be exercised in a manner that conflicts with the
interests of those investors who acquire shares of Common Stock in this
Offering. In addition, under the terms of the Operating Partnership Agreement,
the holders of Units will have certain approval rights with respect to certain
transactions that affect all stockholders of BCP, but which may be exercised in
a manner which does not reflect the interests of all stockholders of BCP. See
"The Company--Certain Relationships; Conflicts of Interest."
    
 
   
    CONFLICTS RELATING TO THE BCP SISTER CORP.  Certain of the officers and
directors of BCP may also serve as officers or directors of the BCP Sister Corp,
if and when formed. If, as expected, ownership of the BCP Sister Corp. and the
Company differ over time, conflicts of interest may develop. Provisions in the
BCP Sister Corp.'s formation documents are expected to (i) provide that the BCP
Sister Corp. may enter into transactions with the Company to the extent deemed
beneficial by their respective boards of directors (and the Company may enter
into an inter-company agreement with the BCP Sister Corp. with respect thereto)
and (ii) generally prohibit the BCP Sister Corp. from engaging in activities or
making investments appropriate for a REIT unless the Company was first given the
opportunity to do so, but elected not to do so, in each instance. The Company
and the Board of Directors may be subject to various potential conflicts
    
 
                                       11
<PAGE>
   
of interest as a result of the relationships between the BCP Sister Corp. and
the Company, including as a result of the possibility that the BCP Sister
Corp.'s formation documents and any inter-company agreements may be negotiated
while BCP and the BCP Sister Corp. are under common control. See "The
Company--Certain Relationships; Conflicts of Interest."
    
 
   
    CONFLICTS RELATING TO THE INCENTIVE RETURN.  As part of the Company's
long-term incentive plans, Beacon Capital Participation Plan, an entity owned
and controlled by the Company's management and established for such purpose, has
been issued the Convertible Unit which shall convert (provided that the
Incentive Return has in fact been earned), at the end of the three-year period
following the completion of the first calendar year following the Closing of the
Original Offering, into a certain number of incentive units of limited
partnership interest in the Operating Partnership ("Incentive Units") (if any)
with a fair market value equal to the Incentive Return. Messrs. Leventhal and
Fortin control and own equity interests in Beacon Capital Participation Plan and
certain members of the Company's senior management also hold minority interests
in Beacon Capital Participation Plan. While the Incentive Return was designed to
align the interests of the Company's senior management with the interests of the
Company's stockholders, no assurance can be given that conflicts will not arise
between such management's interests in the Incentive Return and the
stockholders' interests in the Company. See "The Company--Long-Term Incentive
Plan."
    
 
    POLICIES WITH RESPECT TO CONFLICTS OF INTEREST.  The Company intends to
adopt certain policies designed to eliminate or minimize conflicts of interest,
which will include a requirement that all transactions in which officers or
Directors have a conflicting interest must be approved by a majority of the
Company's Independent Directors. However, there can be no assurance that these
policies will be successful in minimizing or eliminating such conflicts and, if
they are not successful, decisions could be made that might fail to fully
reflect the interests of all stockholders of the Company.
 
    LEVERAGE CAN REDUCE INCOME AVAILABLE FOR DISTRIBUTION.  The Company intends
to leverage its Assets through borrowings, generally through the use of bank
credit facilities, mortgage loans on real estate and other borrowings. To the
extent that changes in market conditions cause the cost of such financing to
increase relative to the income that can be derived from the Assets acquired,
the Company's return on its investment and cash available for distribution to
its stockholders may be adversely affected.
 
   
    Additionally, leverage creates an opportunity for increased returns on
equity, but at the same time creates risks. For example, debt service payments
can reduce the net income available for distributions to stockholders. There can
be no assurance that the Company will be able to meet its debt service
obligations and, to the extent that it cannot, the Company may lose some or all
of its Assets to foreclosure or sale to satisfy its debt obligations. Changes in
interest rates can affect the Company's income by affecting the spread between
the Company's income on its Assets and interest-bearing liabilities, as well as,
among other things, the value of the Company's interest-earning Assets and its
ability to realize gains from the sale of Assets.
    
 
   
    The Company currently intends to adopt guidelines to maintain a debt to
total market capitalization ratio not in excess of 60%. A policy such as this
would allow the Company to incur additional indebtedness as its stock price
increases even though there hasn't necessarily been a corresponding increase in
the Company's ability to service its indebtedness. For purposes of this policy,
the Company's debt to market capitalization ratio is calculated as the Company's
proportionate share of total consolidated and unconsolidated debt as a
percentage of the sum of the market value of outstanding shares of capital stock
of the Company and Units plus the Company's proportionate share of total
consolidated and unconsolidated debt. The Charter and Bylaws, however, do not
limit the amount of indebtedness the Company can incur. Accordingly, the Board
of Directors of the Company could alter or eliminate this policy and would do
so, for example, if it were necessary in order for the Company to continue to
qualify as a REIT. See "Certain Provisions of Maryland Law and of BCP's Charter
and Bylaws" and "Risk Factors--Legal and Tax Risks-- Board of Directors May
Change Certain Policies Without Stockholder Consent."
    
 
                                       12
<PAGE>
   
    RISKS ASSOCIATED WITH HEDGING INVESTMENTS AND INVESTMENTS IN
DERIVATIVES.  Changes in interest rates may adversely affect the Company's
investments. Interest rates are highly sensitive to many factors, including
governmental, monetary and tax policies, domestic and international economic and
political considerations, and other factors beyond the control of the Company.
The Company may employ a hedging strategy to limit the effects of changes in
interest rates on its operations, including engaging in interest rate swaps,
caps, floors and other interest rate exchange contracts. The use of these types
of derivatives to hedge the Company's assets and liabilities carries certain
risks, including the risk that losses on a hedge position will reduce the funds
available for distribution to stockholders and, indeed, that such losses may
exceed the amount invested in such instruments. The Company has no formal policy
with respect to hedging investments or investments in derivatives. There is no
perfect hedge for any investment, and a hedge may not perform its intended use
of offsetting losses on an investment. Moreover, with respect to certain of the
instruments used as hedges for the Company's assets and liabilities, the Company
is exposed to the risk that the counterparties with which the Company trades may
cease making markets and quoting prices in such instruments, which may render
the Company unable to enter into an offsetting transaction with respect to an
open position. In addition, when derivative securities are purchased as hedges,
the price of the hedging vehicle may move more or less than the price movement
of the asset being hedged, thus amplifying any losses incurred. There can also
be no assurance of a correlation between price movements in a hedging vehicle
and an asset being hedged, thus presenting the risk that both the hedging
vehicle and the hedged asset may decline in value at the same time.
Additionally, if there is a default by a party to a hedging transaction, the
Company may only have contractual remedies (which may be limited by bankruptcy,
insolvency or similar laws) pursuant to the agreement related to the
transaction. The profitability of the Company may be adversely affected during
any period as a result of changing interest rates or due to losses incurred in
hedging transactions. For a discussion of the treatment of income from hedging
investments under the REIT qualification requirements of the Code, see "Federal
Income Tax Considerations--Requirements for Qualification--Income Tests."
    
 
    THE COMPANY'S INSURANCE WILL NOT COVER ALL LOSSES.  The Company intends to
maintain comprehensive insurance on each of the Assets, including liability and
fire and extended coverage, in amounts sufficient to permit the replacement of
the Assets in the event of a total loss, subject to applicable deductibles. The
Company will endeavor to obtain coverage of the type and in the amount
customarily obtained by owners of similar properties. There are certain types of
losses, however, generally of a catastrophic nature, including, without
limitation, earthquakes, floods and hurricanes, that may be uninsurable or not
economically insurable. Inflation, changes in building codes and ordinances,
environmental considerations, and other factors may also make it infeasible to
use insurance proceeds to replace an Asset if it is damaged or destroyed. Under
such circumstances, the insurance proceeds received by the Company might not be
adequate to restore its economic position with respect to the affected Asset.
 
    PROPERTY TAXES DECREASE RETURNS ON REAL ESTATE.  Each Asset will be subject
to real and, in some instances, personal property taxes. The real and personal
property taxes on Assets in which the Company invests may increase or decrease
as property tax rates change and as the Assets are assessed or reassessed by
taxing authorities. If property taxes on the Company's investments increase, the
Company's cash available for distribution to its stockholders will be adversely
affected.
 
    COMPLIANCE WITH AMERICANS WITH DISABILITIES ACT AND OTHER CHANGES IN
GOVERNMENTAL RULES AND REGULATIONS MAY BE COSTLY.  Under the Americans with
Disabilities Act of 1990 (the "ADA"), all public properties are required to meet
certain federal requirements related to access and use by disabled persons.
Properties acquired by the Company may not be in compliance with the ADA. If a
property is not in compliance with the ADA, the Company will be required to make
modifications to such property to bring it into compliance, or face the
possibility of an imposition of fines or an award of damages to private
litigants. In addition, changes in governmental rules and regulations or
enforcement policies affecting the use and operation of the properties,
including changes to building codes and fire and life-safety codes, may occur.
If the Company were required to make substantial modifications to the properties
to comply with
 
                                       13
<PAGE>
the ADA or other changes in governmental rules and regulations, the Company's
ability to make expected distributions to its stockholders could be adversely
affected.
 
   
    ADVERSE EFFECT ON RESULTS OF OPERATIONS DUE TO POSSIBLE ENVIRONMENTAL
LIABILITIES.  The Company's operating costs may be affected by the obligation to
pay for the cost of complying with existing environmental laws, ordinances and
regulations, as well as the cost of complying with future legislation with
respect to the Assets, or loans secured by Assets, with environmental problems
that materially impair the value of the Assets. Under various federal, state and
local environmental laws, ordinances and regulations, a current or previous
owner or operator of real property may be liable for the costs of removal or
remediation of hazardous or toxic substances on, under, or in such property.
Such laws often impose liability whether or not the owner or operator knew of,
or was responsible for, the presence of such hazardous or toxic substances. In
addition, the presence of hazardous or toxic substances, or the failure to
remediate properly such property, may adversely affect the owner's ability to
borrow by using such real property as collateral. Persons who arrange for the
transportation, disposal or treatment of hazardous or toxic substances may also
be liable for the costs of removal or remediation of such substances at the
disposal or treatment facility, whether or not such facility is or ever was
owned or operated by such person. Certain environmental laws and common law
principles could be used to impose liability for releases of hazardous
materials, including asbestos-containing materials ("ACMs"), into the
environment, and third parties may seek recovery from owners or operators of
real properties for personal injury associated with exposure to released ACMs or
other hazardous materials. Environmental laws may also impose restrictions on
the manner in which a property may be used or transferred or in which businesses
may be operated, and these restrictions may require expenditures. In connection
with the ownership and operation of properties, the Company may be potentially
liable for any such costs. The cost of defending against claims of liability or
remediating contaminated property and the cost of complying with such
environmental laws could materially adversely affect the Company's results of
operations and financial condition.
    
 
    In connection with the acquisition of Real Estate-Related Assets, the
Company intends to obtain Phase I environmental site assessments ("ESAs")
prepared by qualified independent environmental engineers. The purpose of ESAs
is to identify potential sources of contamination for which the Real
Estate-Related Assets may be responsible and to assess the status of
environmental regulatory compliance. It is possible, however, that these ESAs
will not reveal all environmental liabilities or that such Real Estate-Related
Assets may be subject to material environmental liabilities of which the Company
is unaware.
 
   
    BCP SISTER CORP. WILL HAVE SEPARATE FINANCING.  The Company anticipates that
the BCP Sister Corp., if and when formed, will obtain its own financing,
separate from that of the Company. There can be no assurance that such financing
will be readily available or, if available, that it will be on terms acceptable
to the BCP Sister Corp. In addition, to the extent that the BCP Sister Corp.
should default under such financing, there can be no assurance that the BCP
Sister Corp. would be able to obtain sufficient financing to cure such default
or to ascertain the full impact of such default on the Company.
    
 
   
    NEWLY-ORGANIZED CORPORATION.  The Company was formed on January 21, 1998,
was re-incorporated, through a merger, in Maryland on March 17, 1998, and
consequently has a limited operating history and does not yet have any
established sources of financing. The Company will be dependent upon the
experience and expertise of its senior management in administering its
day-to-day operations. There can be no assurance that the Company's management
will be able to implement successfully the strategies that the Company intends
to pursue. In addition, as a newly-organized company, the Company's policies and
procedures are subject to change over time. See "The Company--Directors and
Executive Officers" and "--Risks Related to Growth Strategy."
    
 
                                       14
<PAGE>
                           INVESTMENT ACTIVITY RISKS
 
   
    APPROPRIATE INVESTMENTS MAY NOT BE AVAILABLE.  Although the Company may
invest in Other Assets as opportunities arise, the Company intends to focus
primarily on acquiring Real Estate-Related Assets consistent with its Investment
Strategy (as defined below). There can be no assurance, however, that the
Company will identify Assets that meet its investment criteria, that the Company
will be successful in acquiring any Assets that may be identified or that any
such Assets will produce a return on the Company's investment. The Company will
have broad authority to invest in Assets consistent with its Investment
Strategy. The Company may invest in highly-leveraged Assets, which may increase
the likelihood of a loss of the Company's Assets through foreclosure. No
assurance can be made that the Company's decisions in this regard will result in
a profit for the Company. Investment in real estate is a highly-competitive
business and the acquisition of Assets is often based on competitive bidding.
Consequently, the Company's inability to identify appropriate Assets may have an
adverse effect on the Company's results of operations and hinder the Company's
growth rate.
    
 
    REAL ESTATE IS ILLIQUID AND VALUE IS DEPENDENT ON CONDITIONS BEYOND THE
COMPANY'S CONTROL.  The Company expects to invest in Assets which may be subject
to varying degrees of risk generally incident to the ownership of real property.
Real estate investments are relatively illiquid. The ability of the Company to
vary its investments in response to changes in economic and other conditions
will be limited. No assurances can be given that the fair market value of any
Assets acquired by the Company will not decrease in the future. The underlying
value of Assets and the Company's income and ability to make distributions to
its stockholders are dependent upon the ability of the Company to operate the
Assets in a manner sufficient to maintain or increase revenues in excess of
operating expenses and debt service or, in the case of real property leased to
one or more lessees, the ability of the lessees to make rent payments. Revenues
may be adversely affected by adverse changes in national or local economic
conditions, competition from other properties offering the same or similar
services, changes in interest rates and in the availability, cost and terms of
mortgage funds, the impact of present or future environmental legislation and
compliance with environmental laws, the ongoing need for capital improvements
(particularly in older structures), changes in real estate tax rates and other
operating expenses, adverse changes in governmental rules and fiscal policies,
civil unrest, acts of God, including, without limitation, earthquakes,
hurricanes and other natural disasters (which may result in uninsured losses),
acts of war, adverse changes in zoning laws, and other factors which are beyond
the control of the Company in whole or in part.
 
    COMPETITION FOR ACQUISITIONS.  Competition exists for investment
opportunities in most sectors of the real estate industry, including all sectors
in which the Company intends to invest. The Company may be competing for Assets
with entities that have substantially greater economic and personnel resources
than the Company or better relationships with sellers of Assets, lenders and
others. These entities may also generally be able to accept more risk than the
Company prudently can manage. Competition may generally reduce the number of
suitable prospective Assets offered to the Company and increase the bargaining
power of property owners seeking to sell, thereby increasing prices.
 
    REAL ESTATE FINANCING RISKS.  The Company is subject to the risks normally
associated with debt financing, including the risk that the Company's cash flow
will be insufficient to meet required debt service. In addition, there is a risk
that, if necessary, existing indebtedness will not be able to be refinanced or
that the terms of such refinancing will not be as favorable as the terms of the
existing indebtedness.
 
    REAL ESTATE INVESTMENT RISKS.  Real property investments are subject to
varying degrees of risks. If the Company's Assets do not generate revenues
sufficient to meet operating expenses, including debt service and capital
expenditures, the Company's cash flow and ability to make distributions to its
stockholders will be adversely affected. An Asset's revenues and value may be
adversely affected by the general economic climate, the local economic climate,
local real estate conditions, the ability of the owner to provide adequate
management, maintenance and insurance, and increased operating costs. Certain
significant
 
                                       15
<PAGE>
expenditures associated with each equity investment (such as mortgage payments,
if any, real estate taxes, insurance and maintenance costs) are generally not
reduced when circumstances cause a reduction in income from the investment.
There are numerous competitors for development and acquisitions of properties,
including other REITs, which may have greater resources than the Company.
 
    RISKS RELATED TO INVESTMENTS IN MORTGAGE LOANS.  Investments in mortgage
loans may carry certain risks which are not present in other types of
investments, including, without limitation, the following:
 
    COMMERCIAL MORTGAGE LOANS MAY INVOLVE A RISK OF LOSS.  Commercial mortgage
loans involve a high degree of risk because of a variety of factors, including
(i) dependency for repayment on successful operation of the mortgaged property
and tenant businesses operating therein, (ii) the fact that such loans are
usually non-recourse to the borrower and (iii) loan terms that include
amortization schedules longer than the stated maturity and provide for balloon
payments at stated maturity rather than periodic principal payments. In
addition, the value of commercial real estate can be affected significantly by
the supply and demand in the market for that type of property.
 
    VOLATILITY OF VALUES OF MORTGAGED PROPERTIES MAY AFFECT ADVERSELY THE
COMPANY'S MORTGAGE LOANS. Commercial real estate values and net operating income
derived therefrom are subject to volatility and may be affected adversely by a
number of factors, including, but not limited to, national, regional and local
economic conditions, local real estate conditions, changed or continued weakness
in specific industry segments, general public perceptions of the safety,
convenience, services and attractiveness of the property, the willingness and
ability of the property's owner to provide capable management and adequate
maintenance, to make capital expenditures and improvements and to provide
leasing concessions, construction quality, age and design, and increases in
operating expenses (such as energy costs).
 
    GENERAL DEFAULT RISKS.  With respect to its investments in mortgage loans,
the Company will be subject to risks of borrower defaults, bankruptcies, fraud
and special hazard losses that are not covered by standard hazard insurance. In
the event of any default under mortgage loans held by the Company, the Company
will bear a risk of loss of principal to the extent of any deficiency between
the value of the collateral and the principal amount of the mortgage loan, and
may not receive interest payments on such mortgage loan which could have a
material adverse effect on the Company's cash flow from operations. In the event
of the bankruptcy of a mortgage loan borrower, the mortgage loan to such
borrower will be deemed to be secured only to the extent of the value of the
underlying collateral at the time of bankruptcy (as determined by the bankruptcy
court), and the lien securing the mortgage loan will be subject to the avoidance
powers of the bankruptcy trustee or debtor-in-possession to the extent the lien
may be unenforceable under state law. Foreclosure of a mortgage loan can be an
expensive and lengthy process which could have a substantial negative effect on
the Company's anticipated return on the foreclosed mortgage loan.
 
    MULTI-SECTOR INVESTMENT STRATEGY.  The Company's current strategy is to
acquire Assets across a variety of real estate product-types in a variety of
geographic locations, initially with a particular emphasis on office Assets.
Accordingly, the Company will be required to maintain expertise, relationships
and market knowledge across a broad range of product-types and geographic
regions, and will be subject to the market conditions affecting each such
product-type in various markets, including such factors as the local economic
climate, business layoffs, industry slowdowns, changing demographics, and local
supply and demand issues affecting each such market. This multi-sector approach
could require more management time, staff support and expense than a company
whose focus is dedicated to a greater extent on a single product-type in fewer
jurisdictions than is contemplated by the Company.
 
   
    GEOGRAPHIC CONCENTRATION OF ASSETS.  The economic performance and value of
the Company's real estate assets will be subject to all of the risks incident to
the ownership and operation of real estate. These include the risks normally
associated with changes in national, regional and local economic and market
conditions. The Assets are located in two markets--East Cambridge, Massachusetts
and Dallas, Texas, and
    
 
                                       16
<PAGE>
   
the Company has no limits on its ability to become even more geographically
concentrated. Local real estate market conditions may include a large supply of
competing space and competition for tenants, including competition based on
rental rates, attractiveness and location of property and quality of
maintenance, insurance and management services. Economic and market conditions
may impact the ability of tenants to make lease payments. In addition, other
factors may adversely affect the performance and value of an Asset, including
changes in laws and governmental regulations (including those governing usage,
zoning and taxes), changes in interest rates and the availability of financing.
If the Assets do not generate sufficient income to meet operating expenses, the
Company's income and ability to make distributions to its stockholders will be
adversely affected.
    
 
    NEW MARKETS.  Although the Company's management has historical experience
with Real Estate-Related Assets and Other Assets and investments in a variety of
geographic areas of the country, it is possible that the Company's expertise in
those markets may not assist the Company in its new markets. In such event, the
Company may be exposed to, among others, risks associated with (i) a lack of
market knowledge and understanding of the local economy, (ii) an inability to
access land and property acquisition opportunities, (iii) an inability to obtain
construction tradespeople, (iv) sudden adverse shifts in supply and demand
factors and (v) an unfamiliarity with local governmental procedures.
 
    RISKS INVOLVED IN ACQUISITIONS THROUGH PARTNERSHIPS AND JOINT
VENTURES.  Instead of purchasing properties directly, the Company may invest as
a partner or a co-venturer. Partnership or joint venture investments may, under
certain circumstances, involve risks not otherwise present, including the
possibility that the Company's partner or co-venturer might become bankrupt,
that such partner or co-venturer might at any time have economic or other
business interests or goals which are inconsistent with the business interests
or goals of the Company, and that such partner or co-venturer may be in a
position to take action contrary to the instructions or the requests of the
Company or contrary to the Company's policies or objectives, including the
Company's policy with respect to maintaining its qualification as a REIT. Such
investments may also have the potential risk of impasse on decisions because
neither the partner nor the co-venturer would have full control over the
partnership or joint venture. The Company will, however, seek to maintain
sufficient control of such partnerships or joint ventures to permit the
Company's objectives to be achieved. There is no limitation under the Company's
organizational documents as to the amount of available funds that may be
invested in partnerships or joint ventures.
 
   
    FOREIGN REAL PROPERTIES ARE SUBJECT TO CURRENCY CONVERSION RISKS AND
UNCERTAINTY OF FOREIGN LAWS. In addition to making investments in domestic
Assets, the Company may invest in Assets located outside the United States.
Risks inherent in investing in real estate located in foreign countries
generally include unexpected changes in regulatory environments, longer accounts
receivable payment cycles, potentially adverse tax consequences and the burden
of complying with a wide variety of foreign laws. Moreover, investments in
foreign Assets may be exposed to the risk of fluctuations in the foreign
exchange rates between the US dollar and the currency in which a transaction is
conducted.
    
 
                              LEGAL AND TAX RISKS
 
   
    TAX RISKS.  BCP intends to operate in a manner so as to qualify as a REIT
for federal income tax purposes. Although BCP does not intend to request a
ruling from the Service as to its REIT status, BCP received, in connection with
the filing of this Registration Statement, an opinion from its counsel, Goodwin,
Procter & Hoar LLP, that, it has been and will be organized in conformity with
the requirements for qualification as a REIT, and its proposed manner of
operation will enable it to qualify as a REIT, which opinion is based on certain
factual and other assumptions and representations with respect to BCP's past and
expected ongoing businesses and investment activities and other customary
matters. No assurance can be given as to the accuracy of such assumptions and
representations or that BCP will be able to comply with them in the future.
Furthermore, such opinion is not binding on the Service or any court, and no
assurance can be given that BCP will operate in a manner so as to qualify or
remain qualified as a REIT.
    
 
                                       17
<PAGE>
The opinion of Goodwin, Procter & Hoar LLP represents only the view of counsel
to BCP based on counsel's review and analysis of existing law, which includes no
controlling precedent and which is subject to change, possibly on a retroactive
basis. See "Federal Income Tax Considerations--Requirements for Qualification."
Furthermore, both the validity of the opinion and the continued qualification of
BCP as a REIT will depend on BCP's satisfaction of certain asset, income,
organizational, distribution and stockholder ownership requirements on a
continuing basis. BCP's operations will not be monitored by Goodwin, Procter &
Hoar LLP to ensure continued compliance with the REIT requirements. If BCP were
to fail to qualify as a REIT in any taxable year, BCP would be subject to
federal income tax (including any applicable alternative minimum tax) on its
taxable income at regular corporate rates, and distributions to stockholders
would not be deductible by BCP in computing its taxable income. Any such
corporate tax liability could be substantial and would reduce the amount of cash
available for distribution to stockholders, which in turn could have an adverse
impact on the value of, and trading prices for, the Common Stock. Unless
entitled to relief under certain REIT provisions of the Code, BCP also would be
disqualified from taxation as a REIT for the four taxable years subsequent to
the year during which BCP ceased to qualify as a REIT. See "Federal Income Tax
Considerations--Requirements for Qualification."
 
    BCP must distribute annually at least 95% of its net taxable income
(excluding any net capital gain) in order to avoid corporate income taxation of
the earnings that it distributes. In addition, BCP will be subject to a 4%
nondeductible excise tax on the amount, if any, by which certain distributions
paid or deemed paid by it with respect to any calendar year are less than the
sum of (i) 85% of its ordinary income for that year, (ii) 95% of its capital
gain net income for that year, and (iii) 100% of its undistributed taxable
income from prior years. The amount of any net long-term capital gains that BCP
elects to retain and pay income tax on will be treated as distributed for
purposes of the 4% excise tax.
 
    BCP intends to make distributions to its stockholders to comply with the 95%
distribution requirement and to avoid the nondeductible excise tax. However,
differences in timing between the recognition of taxable income and the actual
receipt of cash could require BCP to borrow funds or sell assets on a short-term
basis to meet the 95% distribution requirement and to avoid the nondeductible
excise tax. The requirement to distribute a substantial portion of BCP's net
taxable income could cause BCP (i) to sell assets in adverse market conditions,
(ii) to distribute amounts that represent a return of capital, or (iii) to
distribute amounts that would otherwise be spent on future acquisitions, capital
expenditures, or repayment of debt. Gains from the disposition of any asset held
primarily for sale to customers in the ordinary course of business generally
will be subject to a 100% tax. See "Federal Income Tax Considerations--
Requirements for Qualification."
 
    It is anticipated that BCP may purchase mortgage loans. If BCP purchases
such Assets and is deemed to have issued debt obligations having two or more
maturities, the payments on which correspond to payments on such mortgage loans,
such arrangement will be treated as a "taxable mortgage pool" for federal income
tax purposes. If all or a portion of BCP is considered a "taxable mortgage
pool," BCP's status as a REIT generally should not be impaired, but a portion of
BCP's taxable income may be characterized as "excess inclusion income" and
allocated to the stockholders of BCP. Any excess inclusion income (i) could not
be offset by net operating losses of a stockholder, (ii) would be subject to tax
as "unrelated business taxable income" to a tax-exempt stockholder, (iii) would
be subject to the application of federal income tax withholding (without
reduction pursuant to any otherwise applicable income tax treaty), with respect
to amounts allocable to foreign stockholders, and (iv) would be taxable (at the
highest corporate tax rate) to BCP, rather than its stockholders, to the extent
allocable to shares of stock of BCP held by disqualified organizations
(generally, tax-exempt entities not subject to tax on unrelated business taxable
income, including governmental organizations).
 
   
    ADVERSE IMPACT OF FUTURE LEGISLATION REGARDING REITS.  BCP's qualification
as a REIT or its ability to fully utilize the BCP Sister Corp. structure could
be affected as a result of future legislation. In that regard, Congress recently
enacted, and the Clinton Administration signed into law, certain revenue
proposals as part of the Internal Revenue Service Restructuring and Reform Act
of 1998 that included, among other
    
 
                                       18
<PAGE>
   
things, a freeze on the grandfathered status of REITs that are "paired" or
"stapled" with a related operating company. Unlike such "paired" or "stapled"
structures, the proposed BCP Sister Corp. structure would be a "paper clip"
structure in which interests in the BCP Sister Corp. distributed to the
Company's stockholders could be transferred independently from the Company's
Common Stock. Although such legislation does not affect "paper clip" structures,
there can be no assurance that the recently enacted legislation will not place
legislative or judicial scrutiny on the "paper clip" structure or that
legislation adversely affecting such a structure will not be proposed and
enacted. See "Federal Income Tax Considerations--Impact of Future Legislation."
    
 
   
    AGGREGATE STOCK OWNERSHIP LIMIT MAY RESTRICT BUSINESS COMBINATION
OPPORTUNITIES.  In order for BCP to maintain its qualification as a REIT under
the Code, not more than 50% in value of its outstanding shares of stock may be
owned, directly or indirectly, by five or fewer individuals (as defined in the
Code to include certain entities) at any time during the last half of BCP's
taxable year (other than the first taxable year for which the election to be
treated as a REIT has been made). In order to facilitate maintenance of its
qualification as a REIT for federal income tax purposes, and to otherwise
address concerns relating to concentration of stock ownership, the Charter
contains the Aggregate Stock Ownership Limit which generally prohibits any
single stockholder from "beneficially owning" (as such term is defined in the
Charter) more than 9.8% of the issued and outstanding shares of the Company's
Common Stock. Additionally, the Charter contains the Look-Through Ownership
Limit, which generally permits certain mutual funds and certain other
widely-held entities (other than pension plans as described in Section 401(a) of
the Code) to beneficially own up to 15% of the outstanding shares of Common
Stock. The Board of Directors may waive or modify the Aggregate Stock Ownership
Limit and the Look-Through Ownership Limit with respect to one or more persons
if it is satisfied, based upon the receipt of a ruling from the Service or the
advice of tax counsel, that ownership in excess of this limit will not
jeopardize the Company's status as a REIT for federal income tax purposes and
will not cause the Company to be a "pension-held" REIT for federal income tax
purposes. These ownership limits may have the effect of inhibiting or impeding a
change in control and, therefore, could adversely affect the stockholders'
ability to realize a premium over the then-prevailing market price for the
Common Stock in connection with such a transaction. See "Description of
Securities--Transfer Restrictions" and "Federal Income Tax
Considerations--Requirements for Qualification."
    
 
   
    FOREIGN INVESTORS SHOULD CONSIDER TAX RISKS UNDER FIRPTA.  Gain recognized
by a Non-U.S. Stockholder (as defined herein) upon a sale of his Common Stock
generally will be taxed under the provisions of the Foreign Investment in Real
Property Tax Act of 1980 ("FIRPTA") if BCP is not a "domestically controlled
REIT." A "domestically controlled REIT" is defined generally as a REIT in which
at all times during a specified testing period less than 50% in value of the
stock was held directly or indirectly by non-U.S. persons. Although it is
currently anticipated that BCP will be a "domestically controlled REIT" and,
therefore, the re-sale of the Common Stock will not be subject to taxation under
FIRPTA, there can be no assurance that BCP is or will continue to be a
"domestically-controlled REIT." Even if such gain is not subject to FIRPTA, such
gain will be taxable to a Non-U.S. Stockholder under certain other
circumstances. If the gain on the re-sale of the Common Stock were to be subject
to taxation under FIRPTA, the Non-U.S. Stockholder would be subject to the same
treatment as U.S. stockholders with respect to such gain (subject to applicable
alternative minimum tax and a special alternative minimum tax in the case of
nonresident alien individuals). See "Federal Income Tax Considerations--Taxation
of Non-U.S. Stockholders."
    
 
    PLANS SHOULD CONSIDER ERISA RISKS OF INVESTING IN COMMON STOCK.  ERISA is a
broad statutory framework that governs non-governmental employee benefit plans
in the United States. Fiduciaries of pension, profit-sharing or other employee
benefit plans subject to Title I of ERISA ("ERISA Plans"), in consultation with
their advisers, should carefully consider the impact of ERISA and the
regulations of the Department of Labor (the "DOL") thereunder on the ERISA
Plan's decision to invest in the Common Stock. In particular, a fiduciary of an
ERISA Plan should consider whether its decisions with respect to
 
                                       19
<PAGE>
these matters would satisfy the requirements set forth in Part 4 of subtitle B
of Title I of ERISA, including (a) the diversification and prudence requirements
of ERISA, (b) the requirement that the decisions be in the best interests of the
participants and beneficiaries of the ERISA Plan, and (c) the requirement that
the decision be authorized under the appropriate governing instruments and
investment policies of the ERISA Plan.
 
   
    ERISA also prohibits certain transactions involving an ERISA Plan and
persons who are "parties in interest" with respect to the ERISA Plan. In
addition, the Code provides for similar prohibited transaction rules applicable
to "plans" (as defined in Section 4975 of the Code) and "disqualified persons"
with respect to such plans. The fiduciary of an ERISA Plan or a plan described
in Section 4975 of the Code (referred to together herein as "Plans")
contemplating an investment in the Common Stock should consider whether the
acquisition of such Common Stock would result in a prohibited transaction under
ERISA and/or the Code and if so, whether an exemption from these prohibited
transaction rules is available. In addition, the Plan Assets Regulation provides
that, subject to certain exceptions, the assets of an entity in which a Plan
holds an equity interest may be treated as assets of the investing Plan, in
which event, the underlying assets of such entity (and transactions involving
such assets) would be subject to ERISA and applicable provisions of the Code
(including prohibited transaction provisions of ERISA and the Code). The Company
intends to take such steps as may be necessary to qualify BCP and the Operating
Partnership (and any BCP Sister Corp.) for one or more of the exceptions
available under such regulation and, thereby, prevent the assets of the Company
from being treated as assets of any investing Plan. Specifically, the Company
will use its reasonable best efforts to qualify as a "real estate operating
company" (within the meaning of the Plan Assets Regulation) at least until such
time as the Common Stock qualifies as a class of "publicly offered securities"
(as such term is defined in such regulation). In addition, with respect to any
BCP Sister Corp., the Company will take such steps as may be necessary to
qualify such BCP Sister Corp. as an operating company or a venture capital
operating company or for one of the other available exceptions under the Plan
Assets Regulation prior to distributions of its equity interests, although no
assurances can be made in this regard. See "ERISA Considerations--The Treatment
of the Company's Underlying Assets Under ERISA."
    
 
   
    CHANGES IN MANAGEMENT MAY BE DETERRED.  As a Maryland corporation, BCP is
subject to various provisions of the Maryland General Corporation Law (the
"MGCL"), which (a) impose certain restrictions and require certain procedures
with respect to certain business combinations, including, but not limited to,
transactions with holders of more than 10% of the voting power of BCP's equity
securities and (b) limit voting rights for holders of 20% or more of the voting
power of BCP's stock. These provisions could have the effect of discouraging a
takeover or other transaction involving a change in control in which holders of
some, or a majority, of the shares of the Common Stock might receive a premium
for their shares of the Common Stock over the then-prevailing market price or
which such holders might believe to be otherwise in their best interests. The
Charter of the Company exempts from the Maryland statute any business
combination with Alan M. Leventhal, Lionel P. Fortin or current or future
affiliates, associates or other persons acting in concert as a group with either
of Messrs. Leventhal or Fortin. In addition, the right of Beacon Capital
Participation Plan to receive the Incentive Return in the event of a change of
control of the Company (as defined in the Operating Partnership Agreement) may
deter third parties from entering into business combinations with the Company.
See "Certain Provisions of Maryland Law and of BCP's Charter and
Bylaws--Business Combinations," "--Control Share Acquisitions" and "The
Company--Long-Term Incentive Plan."
    
 
    BOARD OF DIRECTORS MAY CHANGE CERTAIN POLICIES WITHOUT STOCKHOLDER
CONSENT.  The major policies of the Company, including its investment policy and
other policies with respect to acquisitions, financing, growth, operations, debt
and distributions, will be determined by its Board of Directors from time to
time. The Board of Directors may amend or revise these and other policies, or
approve transactions that deviate from these policies, from time to time without
a vote of the stockholders. The effect of any such changes may be positive or
negative. See "Certain Provisions of Maryland Law and of BCP's Charter and
Bylaws."
 
                                       20
<PAGE>
    LOSS OF INVESTMENT COMPANY ACT EXEMPTION WOULD ADVERSELY AFFECT THE
COMPANY.  The Company believes that it will not be, and intends to conduct its
operations so as not to become, regulated as an investment company under the
Investment Company Act of 1940. The Investment Company Act exempts entities
that, directly or through majority-owned subsidiaries, are "primarily engaged in
the business of purchasing or otherwise acquiring mortgages and other liens on
and interests in real estate" ("Qualifying Interests"). Under current
interpretations by the Staff of the Commission, in order to qualify for this
exemption, the Company, among other things, must maintain at least 55% of its
assets in Qualifying Interests and also may be required to maintain an
additional 25% in Qualifying Interests or other real estate-related assets. The
assets that the Company may acquire therefore may be limited by the exemption
provisions of the Investment Company Act. In addition, the Company could, among
other things, be required either (a) to change the manner in which it conducts
its operations to avoid being required to register as an investment company or
(b) to register as an investment company, either of which could have an adverse
effect on the Company and the market price for the Common Stock.
 
    LIMITATION ON LIABILITY OF OFFICERS AND DIRECTORS OF THE COMPANY.  The
Charter contains a provision which limits the liability of a director or officer
to BCP and its stockholders for money damages, except for liability resulting
from (a) actual receipt of an improper benefit or profit in money, property or
services or (b) active and deliberate dishonesty established by a final judgment
as being material to the cause of action. See "Certain Provisions of Maryland
Law and of BCP's Charter and Bylaws."
 
                                  OTHER RISKS
 
   
    RESTRICTIONS ON TRANSFERABILITY; LACK OF PUBLIC MARKET.  Each subsequent
purchaser will be required to represent and warrant that it (i) is acquiring
Common Stock for investment and not with a view to distribution or resale, (ii)
understands it must bear the economic risk of an investment in the Common Stock
for an indefinite period of time because the Common Stock has not been
registered with the Commission or any other state or governmental agency, and
(iii) understands that the Common Stock may not be transferred or sold, unless
the Common Stock is registered or an exemption from such registration is
available. There is currently no public market for the Common Stock and there is
no assurance that one will develop. In addition, transfers of the Common Stock
are prohibited if such transfer would (x) violate the Securities Act or any
other applicable federal or state securities laws, rules or regulations, or (y)
cause the Company to fail to comply with any of the requirements for
qualification as a REIT under the Code or (z) cause the Company to violate any
of the restrictions of the Charter. In addition, holders of the Common Stock may
be prevented from relying upon the Registration Statement of which this
Prospectus forms a part for the resale of shares of the Common Stock as a result
of the right of the Company under the Registration Rights Agreement to suspend
its effectiveness during blackout periods (as defined below), required for the
Company to ensure that this Prospectus remains current. See "Description of
Securities-- Registration Rights." Consequently, the purchase of the Common
Stock should be considered a long-term and illiquid investment. See "Description
of Securities--Transfer Restrictions."
    
 
   
    RISK THAT MARKET FOR COMMON STOCK WILL NOT DEVELOP.  The Common Stock
presently has no established trading market. While the Common Stock has been
accepted for trading in the PORTAL Market, a real-time electronic National
Association of Securities Dealers marketplace that facilitates trading in
securities originally offered pursuant to Rule 144A transactions such as the
Company's Original Offering, there can be no assurance that an active trading
market for the Common Stock will develop in the PORTAL Market or elsewhere. In
addition, access to the PORTAL Market, unlike other prominent stock exchanges or
NASDAQ markets, is restricted to certain parties, including qualified
institutions and certain brokers and dealers, and can only be used for the
trading of certain restricted securities. Accordingly, no assurance can be given
as to (i) the likelihood that an active market for the Common Stock will
develop, (ii) the liquidity of any such market, (iii) the ability of the
stockholders to sell their Common Stock, or (iv) the prices that stockholders
may obtain for their Common Stock.

                                  THE COMPANY
 
   
    BCP is a recently-organized Maryland corporation, formed on January 21, 1998
as a Massachusetts corporation and reincorporated as a Maryland corporation on
March 17, 1998, and will elect to be taxed as a REIT under the Code. The
Operating Partnership is a Delaware limited partnership. The principal executive
offices of the Company are located at One Federal Street, 26th Floor, Boston,
Massachusetts 02110. The Company's telephone number is (617) 457-0400.
    
 
    The Company believes that its senior management has long-standing
relationships with institutional owners, lenders, bankers and other real estate
operators and developers which the Company anticipates may provide the Company
with regular access to transaction activity and investment opportunities. In
addition, the operating experience of its senior management gained through the
management of public and private companies provides a unique perspective that is
expected to be particularly valuable as the real estate cycle changes and as the
real estate industry continues its transformation from private to public
capitalization. In addition to the experience gained by the senior management as
senior management of Beacon Properties, they have also been active in the
development, acquisition and management of a broad spectrum of property types,
including lodging, apartment, industrial, retail and mixed-use projects.
 
   
    The Company has entered into management agreements with its wholly-owned
affiliate, Beacon Capital Partners Management, LLC, a Delaware limited liability
company (the "Management Affiliate"), in order to assure that the quality of
services rendered to the Company's tenants is appropriate for the type of
property under management. The Management Affiliate engages sub-agents to handle
the day-to-day and on-site management responsibilities associated with each
property. The Management Affiliate is managed by the Company, and therefore
shares the same management team as is involved in the day-to-day operations of
the Company. No additional compensation is awarded to the officers and employees
as a result of their efforts in handling the business affairs of the Management
Affiliate.
    
 
   
    The Athenaeum Portfolio, Technology Square and the Draper Building are each
managed by the Management Affiliate, and the Management Affiliate has engaged
Spaulding & Slye as sub-agent under an agreement with an initial term through
December 31, 1999. The sub-agent agreement is terminable by the Management
Affiliate without cause or penalty on 30 days' notice to the sub-agent.
    
 
   
    The Breunig Portfolio is currently managed by Bruenig Commercial Management,
Inc., the same management entity that managed the assets for the sellers of the
individual properties which comprised the portfolio. The management agreement is
due to expire on June 30, 1999, although the Company has the option to terminate
the agreement as of January 1, 1999.
    
 
   
    The Sunnyvale Development, once constructed, will be managed by an affiliate
of Menlo Equities. The management arrangement was negotiated as part of the
joint venture structure.
    
 
   
RECENT ACQUISITIONS
    
 
   
    THE ATHENAEUM PORTFOLIO.  On May 1, 1998 the Company purchased a portfolio
of eleven buildings in Cambridge, MA known as The Athenaeum Portfolio. The
mixed-use portfolio consists of approximately 970,000 square feet and contains
office, laboratory and retail uses as well as a 1,530 space parking garage. The
purchase price for the portfolio was $195 million, including the assumption of
approximately $69 million of first mortgage debt. The Company estimates that the
aggregate purchase price is approximately 80% of replacement cost. On May 20,
1998, the Company completed the formation of a joint venture with PW
Acquisitions IX, LLC, an affiliate of PaineWebber, in which both parties hold a
50% interest in the master limited liability company that controls the two
limited liability companies that hold title to The Athenaeum Portfolio. Under
the terms of the joint venture agreement, the Paine Webber affiliate will
reimburse the Company for 50% of all costs associated with the acquisition of
The Athenaeum Portfolio in exchange for its 50% interest in the master limited
liability company.
    
 
                                       22
<PAGE>
    The portfolio is comprised of two components: One Kendall Square and The
Athenaeum House (215 First Street), which are located within close proximity of
M.I.T. Several of the buildings were originally built as manufacturing buildings
at the turn of the century and were fully renovated in the mid-1980's for office
and laboratory uses. A nine-screen cinema was added to the complex in 1994. The
buildings are currently 100% occupied. Major tenants which occupy more than 10%
of the portfolio include: Genzyme, CLAM Associates, Cambridge Neuroscience, and
Mitotix.
 
   
    The Athenaeum Portfolio is located in the East Cambridge office market. The
overall Cambridge office market includes approximately 10 million square feet.
According to Spaulding & Slye, the Cambridge office market had an overall
vacancy rate of 2.4% as of June 30, 1998.
    
 
   
    TECHNOLOGY SQUARE & THE DRAPER BUILDING.  On June 24, 1998 the Company
purchased a four- building complex known as Technology Square and an adjacent
building known as The Draper Building from a partnership managed by Prudential.
The properties are located in Cambridge, MA, adjacent to One Kendall Square
(described above) and M.I.T. and consist of 1,026,000 square feet. The purchase
price for the properties was $123 million. As part of the purchase, Prudential
accepted approximately $51.4 million in the form of units of the Operating
Partnership at a blended rate of $20.31 per unit. There are no mortgages
outstanding against these properties.
    
 
   
    Technology Square is currently 100% leased to two tenants: M.I.T. and
Polaroid Corporation. The leases with these tenants expire in mid-1999. Average
net lease rates in place are $6.53 per square foot, which the Company believes
to be substantially below current market. Accordingly, the Company believes it
will be able to re-let Technology Square at current market rents. The Company
intends to re-develop and re-lease the property over the next 18-24 months and
projects substantial increases in net operating income as the property is
stabilized at current market net rents, which the Company believes to be
approximately $24 per square foot. The scope of the re-development is currently
under review by the Company and, therefore, the estimated cost thereof has not
yet been established. It is anticipated by management that any such
redevelopment would be financed by the Company from cash on hand or project
financing. The Draper Building is 100% leased to Draper Labs on a long-term
lease which expires on October 20, 2001. The lease contains extension options
through October 2051, pursuant to which the tenant has an option, under certain
circumstances, to acquire The Draper Building.
    
 
   
    Technology Square and The Draper Building are located in the East Cambridge
office market. The overall Cambridge office market includes approximately 10
million square feet. Upon completion of this acquisition, the Company will own
approximately 2 million square feet of office and commercial space in the
Cambridge market, including The Athenaeum Portfolio, Technology Square and The
Draper Building. According to Spaulding & Slye, the Cambridge office market had
an overall vacancy rate of 2.4% as of June 30, 1998.
    
 
   
    THE BRUENIG PORTFOLIO.  On July 1, 1998, the Company acquired a 1,335,000
square foot portfolio of seven office properties and seven research &
development (R&D) properties located in suburban Dallas, TX. The properties were
purchased from Breunig Commercial Management, Inc., a Dallas-based real estate
owner and manager for a total consideration of $91.2 million, including the
assumption of approximately $21.8 million of first mortgage debt. The purchase
price is approximately $68 per square foot, which the Company estimates to be
approximately 65% of the replacement cost of the assets.
    
 
   
    The properties are predominately located along the North Central Expressway
corridor in North Dallas. As measured on a square foot basis, the portfolio is
approximately two-thirds office (842,000 s.f.), and one-third R&D (493,000 s.f.)
The current average occupancy rate for the portfolio is 95%. However, nearly 54%
of the space in the buildings is expiring over the next 3 years, providing an
opportunity to substantially increase the net operating income as the properties
are re-leased at current market rents. Average net rents at the properties are
more than $3.00/s.f. (or nearly 56%) below what the Company estimates to be
current market rents. Major tenants include: Blue Cross, Texas Instruments,
Dallas Teachers Credit, Puretan, Inc., and Specialized Resources.

    The overall Dallas office market contains 133 million square feet of space.
According to Cushman & Wakefield, as of the end of the Second Quarter of 1998,
the overall vacancy rate was 13.1%. The office properties in The Breunig
Portfolio are located primarily in the North Central Expressway and LBJ Freeway
submarkets where the Second Quarter vacancy rates were 11.9% and 5.5%,
respectively.
    
 
   
    The Office/Showroom category of the Dallas Industrial market (which includes
R&D space), contains 49.5 million square feet of space. The overall vacancy rate
as of the end of the Second Quarter was 5.4%. The R&D properties in The Breunig
Portfolio are located primarily in the Richardson/Plano and North Dallas
submarkets, where the Second Quarter 1998 vacancy rates were 3.4% and 3.5%,
respectively.
    
 
   
    In the opinion of management, each of the Company's properties is adequately
insured.
    
 
   
PENDING ACQUISITION
    
 
   
    SUNNYVALE DEVELOPMENT.  On August 9, 1998, the Company entered into a joint
venture agreement with Mathilda Partners LLC, an affiliate of Menlo Equities, a
California based developer, by which the Company has agreed to fund 87.5% of the
equity required to develop two Class A office buildings and Mathilda Partners
LLC has agreed to fund 12.5% of such equity. After each party receives a 12% per
annum return on their equity, the profits from the venture will be split
equally. The venture is under contract to acquire a twelve-acre site on Mathilda
Avenue in Sunnyvale, California, on which the venture plans to construct two
four-story office buildings with surface parking. Although it is anticipated
that the buildings will contain approximately 267,000 square feet, certain
changes in the entitlements for the property will be required to increase the
permitted density from the currently permitted 187,000 square feet. Neither
building has been pre-leased. In addition to funding approximately 40% of the
development expenditures (including the acquisition of the land) from cash
contributions, the venture intends to finance the balance of those expenditures
with a construction loan from an institutional lender. At this point in time,
the scope of the development budget has not been finalized, but it is
anticipated to be approximately $57.0 million if the full 267,000 square feet
are constructed. The site for the development is in the Sunnyvale office market,
which includes approximately 21.5 million square feet. According to Colliers
Parrish International, the Sunnyvale office research and development market had
an overall vacancy rate of 4.2% as of May 1, 1998.

BOARD OF DIRECTORS AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
   
    The Board of Directors is divided into three classes of directors. The
initial terms of the first, second and third classes will expire in 1999, 2000
and 2001, respectively. Beginning in 1999, directors of each class will be
chosen for three-year terms upon the expiration of their current terms and each
year one class of directors will be elected by the stockholders. All officers
serve at the discretion of the Board of Directors. Each of the Directors who are
not employees of the Company (the "Independent Directors") receive an annual
director's fee of $20,000. Each Independent Director also receives $1,000 for
each regular quarterly or special meeting of the Board of Directors attended,
$1,000 for each committee meeting attended and $250 for each special telephonic
committee meeting or meeting of the Board of Directors in which such Independent
Director has participated. Independent Directors are also reimbursed for
reasonable expenses incurred to attend director and committee meetings.
Independent Directors may make an election, subject to approval of the Board's
compensation committee (the "Compensation Committee"), to receive options to
purchase Common Stock at a discount to fair market value in lieu of cash fees or
to receive deferred stock units. Officers of the Company who are Directors will
not be paid any directors' fees. Independent Directors receive, upon initial
election to the Board of Directors, an option to purchase 5,000 shares of Common
Stock, and annually thereafter will receive an option to purchase 5,000 shares
of Common Stock. All options granted to Independent Directors vest on the date
of grant.
    
 
    The Charter of BCP provides that, except in the case of a vacancy, a
majority of the members of the Board of Directors will be Independent Directors.
Vacancies occurring on the Board of Directors among the Independent Directors
will be filled by the vote of a majority of the Directors, including a majority
of the Independent Directors. The Compensation Committee will consist solely of
Independent Directors, except that Mr. Leventhal or his designee may serve as an
EX OFFICIO, non-voting member of the Compensation Committee.
 
    The Maryland General Corporation Law (the "MGCL") permits a corporation to
include in its charter a provision limiting the liability of directors and
officers to the corporation or its stockholders for money damages, except (i) to
the extent that it is proved that the director or officer actually received an
improper benefit or profit in money, property or services or (ii) if a judgment
or other final adjudication is
 
                                       39
<PAGE>
entered in a proceeding based on a finding that the director's or officer's
action or failure to act was the result of active and deliberate dishonesty and
was material to the cause of action adjudicated in the proceeding. The Charter
limits the liability of the Board of Directors and officers to the Company to
the fullest extent permitted from time to time by Maryland law. See "Certain
Provisions of Maryland Law and BCP's Charter and of Bylaws--Limitation of
Liability and Indemnification."
 
    The Charter of the Company authorizes it, to the maximum extent permitted by
Maryland law, to obligate itself to indemnify and to pay or reimburse reasonable
expenses in advance of final disposition of a proceeding to (a) any present or
former director or officer or (b) any individual who, while a director of the
Company and at the request of the Company, serves or has served another
corporation, REIT, partnership, joint venture, trust, employee benefit plan or
any other enterprise as a director, officer, partner or trustee of such
corporation, REIT, partnership, joint venture, trust, employee benefit plan or
other enterprise from and against any claim or liability to which such person
may become subject or which such person may incur by reason of his or her status
as a present or former director or officer of the Company. The Bylaws of the
Company obligate it, to the maximum extent permitted by Maryland law, to
indemnify and to pay or reimburse reasonable expenses in advance of final
disposition of a proceeding to (a) any present or former director or officer who
is made a party to the proceeding by reason of his service in that capacity or
(b) any individual who, while a director of the Company and at the request of
the Company, serves or has served another corporation, REIT, partnership, joint
venture, trust, employee benefit plan or any other enterprise as a director,
officer, partner or trustee of such corporation, REIT, partnership, joint
venture, trust, employee benefit plan or other enterprise and who is made a
party to the proceeding by reason of his service in that capacity. The Charter
and Bylaws also permit the Company to indemnify and advance expenses to any
person who served a predecessor of the Company in any of the capacities
described above and to any employee or agent of the Company or a predecessor of
the Company.
 
    The MGCL requires a corporation (unless its charter provides otherwise,
which the Company's Charter does not) to indemnify a director or officer who has
been successful, on the merits or otherwise, in the defense of any proceeding to
which he is made a party by reason of his service in that capacity. The MGCL
permits a corporation to indemnify its directors, officers and certain other
parties against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by them in connection with any proceeding to which they may be
made a party by reason of their service to, or at the request of, the
corporation, unless it is established that (a) the act or omission of the
indemnified party was material to the matter giving rise to the proceeding and
(i) the act or omission was committed in bad faith or (ii) the act or omission
was the result of active and deliberate dishonesty, (b) the indemnified party
actually received an improper personal benefit in money, property or services or
(c) in the case of any criminal proceeding, the indemnified party had reasonable
cause to believe that the act or omission was unlawful. However, under the MGCL,
a Maryland corporation may not indemnify for an adverse judgment in a suit by or
in the right of the corporation or for a judgment of liability on the basis that
personal benefit was improperly received, unless in either case a court orders
indemnification and then only for expenses. In addition, the MGCL permits a
corporation to advance reasonable expenses to a director or officer upon the
corporation's receipt of (a) a written affirmation by the director or officer of
his good faith belief that he has met the standard of conduct necessary for
indemnification by the corporation and (b) a written undertaking by him or on
his behalf to repay the amount paid or reimbursed by the corporation if it shall
ultimately be determined that the standard of conduct was not met. Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or persons controlling BCP pursuant to the
foregoing provisions, BCP has been informed that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

LONG-TERM INCENTIVE PLAN
 
   
    The Company's compensation and incentive plans are designed to align the
interests of the Company's executive management with the interests of the
Company's stockholders. The Company's Long-Term Incentive Plan is designed to
reward certain members of management for growth of the Company's Funds from
Operations in excess of a specified benchmark as described below. If the
Company's Funds from Operations exceeds this benchmark, management will be
entitled to receive an incentive return determined in the manner described below
(the "Incentive Return"), which shall be calculated at the end of the three year
period following the completion of the first calendar year following the Closing
(the "Determination Date").
    
 
   
    The Incentive Return shall equal the product of (A) 12% of the dollar amount
by which (i) the Actual Return exceeds (ii) the Base Return; multiplied by (B)
the weighted average of shares of Common Stock and Units outstanding for the 12
months immediately preceding the Determination Date; multiplied by (C) the
Company's Multiple (as defined below). The Incentive Return is a function of the
amount by which the Actual Return exceeds the Base Return. If the Actual Return
does not exceed the Base Return, no Incentive Return will have been earned.
Likewise, the maximum Incentive Return is limited by the amount the Actual
Return exceeds the Base Return.
    
 
    For the purposes of calculating the Incentive Return:
 
        "Actual Return" means the Funds from Operations (before the Incentive
    Return) of the Company per share of Common Stock and per Unit for the 12
    months immediately preceding the Determination Date;
 
        "Base Return" means an amount equal to what the Company's Funds from
    Operations would have been for the twelve month period immediately preceding
    the Determination Date assuming a
 
                                       41
<PAGE>
    benchmark cumulative rate of return on the Offering Price equal to 10% per
    annum, compounding quarterly, calculated since the beginning of the calendar
    quarter following the date of Closing.
 
        "Funds from Operations", as defined by NAREIT, means net income
    (computed in accordance with GAAP), excluding gains (or losses) from debt
    restructuring and sales of property, plus depreciation and amortization (in
    each case, only real estate-related assets), and after adjustments for
    unconsolidated partnerships and joint ventures; and
 
        "Multiple" means the price of the Company's Common Stock (as defined
    below) divided by the Company's Funds from Operations per share for the
    fiscal quarter ending on the Determination Date on an annualized basis.
 
    For the purposes of calculating the Multiple, the price of the Company's
Common Stock will be calculated as follows:
 
        (1) where there exists a public market for the Company's Common Stock,
    the price of the Company's Common Stock will be the average of the closing
    bid and asked prices of the Common Stock quoted in the Over-The-Counter
    Market Summary or the last reported sale price of the Common Stock or the
    closing price quoted on the NASDAQ System or on any exchange on which the
    Common Stock is listed, whichever is applicable, as published in THE WALL
    STREET JOURNAL for the 90 calendar days prior to the calculation of the
    Multiple.
 
        (2) if no public market for the Common Stock exists at the time of such
    exercise, the price of the Company's Common Stock will be determined by a
    single, independent appraiser to be selected by a committee composed of
    Independent Directors, which appraiser shall appraise the fair market value
    of one share of the Company's Common Stock within 30 days of its selection
    within such guidelines as shall be determined by the committee of
    Independent Directors.
 
    The right to receive the Incentive Return, in the event of a change in
control of the Company (as such term is defined in the Operating Partnership
Agreement), shall automatically accelerate and the determination of the
Incentive Return shall be appropriately adjusted to reflect such acceleration as
determined by the Company's Compensation Committee. The Company anticipates that
the mechanism by which the Incentive Return will be adjusted as a result of a
change of control shall be established by the Compensation Committee in advance
of any such event.
 
   
    The Long-Term Incentive Plan takes the form of a Convertible Unit which has
been issued to Beacon Capital Participation Plan. The Convertible Unit is
convertible at the Determination Date (assuming the Incentive Return has in fact
been earned) into a certain number of incentive units of limited partnership
interest in the Operating Partnership (the "Incentive Units") with a fair market
value equal to the amount of the Incentive Return. The Incentive Units share
equally on a unit-by-unit basis with the outstanding Units in all distributions
by the Operating Partnership and are redeemable for cash or, at the election of
the Independent Directors of BCP, exchangeable for shares of Common Stock. See
"Operating Partnership Agreement."
    
 
   
    Certain members of the Company's senior management have been, and from time
to time may be, offered the opportunity to acquire equity interests in Beacon
Capital Participation Plan. Messrs. Leventhal and Fortin, with the assistance
and advice of the Company's Compensation Committee, shall decide who shall be
offered equity interests in Beacon Capital Participation Plan. Members of BCP's
senior executive management who become equity holders of Beacon Capital
Participation Plan shall be allocated an interest in (i) the Incentive Return,
subject to certain vesting restrictions, and (ii) the Units held by Beacon
Capital Participation Plan. On the Determination Date, 50% of each such equity
holders' interests in the Incentive Return shall vest and on the first
anniversary of the Determination Date each equity holders' interests in the
Incentive Return shall be fully vested. An equity holder of Beacon Capital
Participation Plan whose employment with the Company terminates prior to full
vesting of his or her interest in the Incentive Return shall automatically
forfeit any such unvested interest and the general partner of Beacon
    
 
                                       42
<PAGE>
   
Capital Participation Plan, an entity controlled by Messrs. Leventhal and
Fortin, shall have the authority to reallocate such interest as they deem
appropriate. See "Risk Factors--Economic and Business Risks-- Conflicts of
Interest."
    
 
   
    There can be no assurance that the awards under the Long-Term Incentive
Plan, or the stock options or other rewards pursuant to the Stock Incentive Plan
described below, will provide an incentive to the Company's management to
enhance the value of the Common Stock or, if properly incentivized, that
management's efforts will, in fact, result in the enhancement in value of the
Common Stock. In addition, the Incentive Return, if paid, could substantially
reduce cash available for distribution to stockholders. See "Risk
Factors--Economic and Business Risks--Conflicts of Interest."
    
 
    Funds from Operations does not represent cash generated from operating
activities in accordance with GAAP and should not be considered as an
alternative to net income as an indication of the Company's performance or to
cash flows as a measure of liquidity or ability to make distributions.
 
   
    The ability of the Company to generate Funds from Operations in excess of
the Base Return described above and, consequently, the ability of Beacon Capital
Participation Plan to earn the Incentive Return described in the preceding
paragraph, is dependent upon the Company's ability to execute successfully the
investment strategies described in this Prospectus, and other factors, many of
which are not within the Company's control.
    
 
STOCK INCENTIVE PLAN
 
    The Company has adopted a Stock Incentive Plan, which provides for options
to purchase shares of Common Stock. The Stock Incentive Plan authorizes the
grant of options and other stock-based awards to the Company's executive
officers, Directors and employees and other key persons. The purpose of the
Stock Incentive Plan is to provide a means of performance-based compensation in
order to provide incentive for the members of the Company's management to
enhance the value of BCP's Common Stock.
 
    PLAN ADMINISTRATION; ELIGIBILITY.  The Stock Incentive Plan is administered
by the Compensation Committee of the Board of Directors (the "Administrator").
 
    The Administrator will have full power to select, from among the persons
eligible for awards, the individuals to whom awards will be granted, to make any
combination of awards to participants, and to determine the specific terms of
each award, subject to the provisions of the Stock Incentive Plan. Persons
eligible to participate in the Stock Incentive Plan are generally those
executive officers, Independent Directors and employees of the Company and other
key persons who are responsible for or contribute to the management, growth or
profitability of the Company, as selected from time to time by the Administrator
in its sole discretion.
 
    RESERVED SHARES.  The maximum number of shares of Common Stock reserved and
available for issuance under the Stock Incentive Plan will be such aggregate
number of shares as does not exceed the sum of (i) 12% of the outstanding equity
interests in the Company (including Common Stock and Units subject to redemption
rights) (as determined as of the Final Original Offering Closing Date) plus (ii)
as of the last business day of each calendar quarter ending after the Final
Original Offering Closing Date, an additional positive number equal to 10% of
any net increase of outstanding equity interests in the Company.
 
    STOCK OPTIONS.  The Stock Incentive Plan permits the granting of (i) options
to purchase Common Stock intended to qualify as incentive stock options
("Incentive Options") under Section 422 of the Code and (ii) options that do not
so qualify ("Non-Qualified Options"). The option exercise price of each option
will be determined by the Administrator but may not be less than 100% of the
fair market value of the Common Stock on the date of grant in the case of
Incentive Options, and may not be less than 25% of the fair market value of the
Common Stock on the date of grant in the case of Non-Qualified Options. Plan
 
                                       43
<PAGE>
participants may elect with the consent of the Administrator, to receive
discounted Non-Qualified Options in lieu of cash compensation. To qualify as
Incentive Options, options must meet additional federal tax requirements,
including limits on the value of shares subject to Incentive Options which first
become exercisable in any one calendar year, and a shorter term and higher
minimum exercise price in the case of certain large stockholders.
 
    The term of each option will be fixed by the Administrator and may not
exceed ten years from date of grant in the case of an Incentive Option. The
Administrator will determine at what time or times each option may be exercised
and, subject to the provisions of the Stock Incentive Plan, the period of time,
if any, after retirement, death, disability or termination of employment during
which options may be exercised. Options may be made exercisable in installments,
and the exercisability of options may be accelerated by the Administrator.
 
    OTHER STOCK BASED GRANTS.  The Administrator may also award, subject to such
conditions and restrictions imposed by the Administrator, shares of Common Stock
or Units (or other interests in the Operating Partnership) which may or may not
be subject to a risk of forfeiture; deferred stock units which are ultimately
payable in the form of shares of Common Stock; performance share awards to
participants entitling the participant to receive shares of Common Stock upon
the achievement of individual or Company performance goals; dividend equivalent
rights (which entitle the recipient to receive credits for dividends that would
be paid if the recipient had held specified shares of Common Stock); awards of
capital stock other than Common Stock and other awards that are valued in whole
or in part by reference to or are otherwise based on, Common Stock.
 
    CHANGE OF CONTROL PROVISIONS.  The Stock Incentive Plan provides that unless
otherwise provided in the award agreement, all awards becomes fully vested and
non-forfeitable upon a change of control of the Company (as defined in the Stock
Incentive Plan).
 
    AMENDMENTS AND TERMINATION.  The Board of Directors may amend or terminate
the Stock Incentive Plan at any time, except that approval by BCP's stockholders
is required for such amendments or termination to the extent the Board of
Directors determines that such approval is necessary or desirable in order to
meet certain exceptions under securities, tax and other applicable laws.
 
EMPLOYMENT AGREEMENTS; COVENANTS NOT TO COMPETE
 
    Messrs. Leventhal and Fortin have entered into employment agreements (the
"Employment Agreements") with the Company. The Employment Agreements, which are
for a term of three years from the Closing Date of the Original Offering ,
contain non-competition, change in control and other provisions customary for
senior executives of publicly-traded REITs. See "--Management Compensation."
 
CREDIT FACILITY
 
    The Company intends to obtain a commitment from a lender to enter into a
credit facility (the "Credit Facility") to provide the Company with an available
source of debt financing. See "Risk Factors-- Investment Activity Risks--Real
Estate Financing Risks" and "Plan of Distribution."
 
CERTAIN RELATIONSHIPS; CONFLICTS OF INTEREST
 
   
    Messrs. Leventhal and Fortin have formed Beacon Capital Participation Plan
and have offered equity interests in Beacon Capital Participation Plan to
certain members of the Company's senior management. In addition, Messrs.
Leventhal and Fortin, individually and through Beacon Capital Participation
Plan, have purchased, directly from the Company and the Operating Partnership, a
combination of shares of Common Stock and Units for an aggregate purchase price
of approximately $15 million, representing approximately 3.2% of the equity
interests in the Company on a fully diluted basis. In addition, the
    
 
                                       44
<PAGE>
   
Company has established the Long-Term Incentive Plan to align the interests of
management with the interests of the Company's stockholders, pursuant to which
Beacon Capital Participation Plan has been issued, for no additional
consideration, a Convertible Unit of the Operating Partnership. Provided that
the Incentive Return has, in fact, been earned, at the end of the three year
period following the completion of the first calendar year following the Closing
Date of the Original Offering, the Convertible Unit will convert into a certain
number of Incentive Units with a fair market value equal to the Incentive
Return. See "The Company--Long-Term Incentive Plan" and "Risk Factors--Economic
and Business Risks-- Conflicts of Interest." Beacon Capital Participation Plan
has been granted certain registration rights with respect to any Common Stock
issuable upon an exchange of Units and Incentive Units held by Beacon Capital
Participation Plan. See "Description of Securities--Registration Rights." BCP's
senior management, by holding equity interests in Beacon Capital Participation
Plan, is able to participate in the Incentive Return subject to certain vesting
restrictions. See "The Company--Long-Term Incentive Plan" and "Risk
Factors--Economic and Business Risks--Conflicts of Interest." Although the
Company believes that the Long-Term Incentive Plan will serve to align the
interests of management with the interests of the Company's stockholders, the
possibility exists that conflicts of interest could arise between the interests
of management and the interests of the Company's stockholders relating to the
Long-Term Incentive Plan and the conversion of the Convertible Unit into
Incentive Units, including for example, with respect to the timing of
transactions which could affect the Company's Funds from Operations in the
fiscal year or fiscal quarter in which the Convertible Unit converts into the
Incentive Units, if any.
    
 
   
    After the formation of the BCP Sister Corp. and the distribution of the BCP
Sister Corp.'s equity interests to the partners and stockholders of the Company,
the BCP Sister Corp. will rely on the Company to provide it investments. The
Company expects that the provisions in the BCP Sister Corp.'s formation
documents will (i) provide that the BCP Sister Corp. will enter into
transactions with the Company to the extent deemed beneficial by their
respective boards of directors (and the Company may enter into an intercompany
agreement with the BCP Sister Corp. with respect thereto) and (ii) generally
prohibit the BCP Sister Corp. from engaging in activities or making investments
appropriate for a REIT (for a specified time period) unless the Company was
first given the opportunity to do so but elected not to do so. While it is the
Company's intention that the Company and the BCP Sister Corp. have separate
boards of directors, to the extent that there is overlap, the Board of Directors
may be subject to various potential conflicts of interest as a result of the
relationships with the BCP Sister Corp. and the Company. See "Risk
Factors--Investment Activity Risks--Conflicts of Interest." In addition, to the
extent that the BCP Sister Corp. requires separate financing arrangements,
conflicts may arise between the BCP Sister Corp. and the Company to the extent
that the BCP Sister Corp. has difficulty obtaining or maintaining such
financing. See "Risk Factors--Economic and Business Risks--BCP Sister Corp. Will
Have Separate Financing."
    
 
    The market in which the Company expects to purchase assets is characterized
by rapid evolution of products and services and, thus, there may in the future
be relationships between the Company and the BCP Sister Corp. and its
affiliates, in addition to those described herein.

                                USE OF PROCEEDS
 
    The Selling Stockholders will receive all of the proceeds from the sale of
the Offered Securities offered hereby. The Company will not receive any of the
proceeds from the sale by the Selling Stockholders of the Offered Securities.
 
                              DISTRIBUTION POLICY
 
    In order to avoid corporate income taxation on the earnings that it
distributes, BCP must distribute to its stockholders an amount at least equal to
(i) 95% of its REIT taxable income (determined before the deduction for
dividends paid and excluding any net capital gain) plus (ii) 95% of the excess
of its net income from foreclosure property over the tax imposed on such income
by the Code less (iii) any excess noncash income (as determined under the Code).
See "Federal Income Tax Considerations." The actual amount and timing of
distributions, however, will be at the discretion of the Board of Directors and
will depend upon the financial condition of BCP in addition to the requirements
of the Code.
 
    Subject to the distribution requirements referred to in the immediately
preceding paragraph, BCP intends, to the extent practicable, to invest
substantially all of the principal from repayments, sales and refinancings of
the Company's assets in Assets. BCP may, however, under certain circumstances,
make a distribution of principal or of assets. Such distributions, if any, will
be made at the discretion of BCP's Board of Directors.
 
    It is anticipated that distributions generally will be taxable as ordinary
income to non-tax exempt stockholders of BCP, although a portion of such
distributions may be designated by BCP as long-term capital gain or may
constitute a return of capital. BCP will furnish annually to each of its
stockholders a statement setting forth distributions paid during the preceding
year and their federal income tax status. For a discussion of the federal income
tax treatment of distributions by BCP, see "Federal Income Tax
Considerations--Taxation of the Company" and "--Taxation of Taxable U.S.
Stockholders."
 
   
    The declaration and payment of dividends by any BCP Sister Corp. (if and
when formed) will be made by the BCP Sister Corp.'s board of directors from time
to time based on such considerations as the BCP Sister Corp.'s board of
directors deems relevant, will be payable only out of funds legally available
therefor under the laws of the state of formation of the BCP Sister Corp. and
will be subject to any limitations which may be contained in the debt
instruments of the BCP Sister Corp. See "Risk Factors--Economic and Business
Risks--Conflicts of Interest."

                      INVESTMENT STRATEGIES AND EXPERIENCE
 
INVESTMENT STRATEGIES AND EXPERIENCE
 
   
    BCP's investment strategy will be driven by the background and experience of
the senior management of the Company, including management's experience with
public and private real estate companies. As the capitalization of the real
estate industry continues to evolve toward a publicly-held format, BCP believes,
based upon its management's experience through several economic cycles in the
real estate industry, that numerous investment opportunities will continue to
emerge that reflect several primary shifts in the real estate industry. These
shifts include:
    
 
    - rapid recovery of the real estate markets
 
    - extraordinary growth of the public capital markets for real estate
      companies
 
    - continued consolidation of the ownership of real estate
 
    - alignment of interests between investors and management
 
    - recognition of real estate companies as operating businesses
 
   
    These factors have resulted in significant investment opportunities in real
estate, including arbitrage between public and private market pricing. It is
BCP's belief that as the real estate industry continues its transformation (and
recognizing that real estate is still fundamentally a cyclical business),
disparities in pricing and capital availability, as well as ineffective
management of real estate assets by others, will provide opportunities for
skilled and experienced management teams, such as the Company's management team.
Initially, the Company expects to focus primarily on opportunities in the office
sector. As the real estate market cycle advances, the Company expects additional
opportunities to emerge in non-office market sectors, including opportunities in
the lodging, residential and industrial sectors. See "Risk Factors--Investment
Activity Risks--Multi-Sector Investment Strategy." The Company believes that,
increasingly, management expertise and creative real estate solutions will be
required for successful real estate companies. BCP's management team has a
proven track record in this regard in office as well as with other property
types. Based on these observations, BCP intends to identify, create and realize
value for the Company in its investment in Real Estate-Related Assets (as
outlined below). Several themes underlie this strategy:
    
 
    - RELATIONSHIPS--BCP's management will draw upon its extensive network of
      domestic and foreign institutional relationships established over the past
      twenty years in the public and private company sectors. These
      relationships have provided, and are expected to continue to provide,
      early and sometimes exclusive access to negotiated transactions and
      avoidance of competitive auctions.
 
    - OPERATING COMPANY EXPERTISE--BCP will identify opportunities where its
      expertise in actively managing both public and private real estate
      companies can be applied to under-performing real estate assets or real
      estate companies.
 
    - INDUSTRY TRENDS--BCP will identify and capitalize on industry trends that
      emerge as the market continues its transformation and maturation process.
 
    The Company initially intends to focus its investment activity in the
following types of Real Estate-Related Assets: (i) value-added repositionings
and discounted purchases; (ii) development and re-development; (iii)
multiple-property portfolios; (iv) joint ventures and strategic partnerships;
and (v) real estate companies and real estate-related businesses.
 
    (i) VALUE-ADDED REPOSITIONINGS AND DISCOUNTED PURCHASES. The Company expects
to target investments in under-utilized or poorly capitalized single assets and
portfolios that may be recapitalized on advantageous terms and repositioned with
the expectation of returns greater than those that could be achieved by
acquiring a stabilized property. These investments may include the purchase of
the property at a discount to replacement cost or the purchase of the underlying
debt thereon often at a discount to face value. In today's dynamic real estate
industry with an ever-changing and cyclical economy and changing demographic
characteristics, there generally will be opportunities to take better advantage
of well-located
 
                                       47
<PAGE>
and structurally sound properties. Opportunities in this area include
acquisitions of properties and portfolios from controlling parties who are not
focused on maximizing value in these assets, whether because they have lost
economic incentive or because they are non-strategic or inefficient owners of
real estate. In addition, opportunities may involve substantial rehabilitation
or redevelopment and ground-up development where market conditions warrant new
construction. Investments in this area may benefit from the Company's
value-added problem-solving and structuring capabilities, as well as from the
skills of operating partners in joint venture investments. The Company believes
that there may be an availability of these opportunities due to short-term
issues with the properties (such as vacancies) that may not appeal to larger
publicly-traded REITs.
 
   
    (ii) DEVELOPMENT AND RE-DEVELOPMENT. The Company expects that it will
target, on a selected basis, investments requiring strategic ground-up
development or re-development of existing properties that can benefit from
repositioning. Based on the current stage of the real estate business cycle, the
Company believes that attractive development opportunities are presenting
themselves in a number of markets. The Company expects to seek out opportunities
where market vacancy rates and market rents justify new construction and where
job growth will support new demand for office space. Development and
redevelopment of real estate was a primary element of Beacon Properties'
business strategy under the supervision of the Company's senior management. The
Company's management has significant experience in numerous urban and suburban
development projects in Boston and throughout the United States, including
prominent office and mixed-use developments, particularly in Boston. In
addition, BCP's principals also have development expertise in other property
types, including lodging, industrial, retail, apartments and mixed-use projects.
    
 
    (iii) MULTIPLE PROPERTY PORTFOLIOS. The Company expects to target real
estate acquisitions resulting from corporate divestitures from users, financial
institutions, and other non-strategic and inefficient owners of real estate.
Many domestic and foreign corporations and institutions (i.e., insurance
companies, pension funds and endowments) have made direct investments in real
estate assets or, on occasion, have established full-service real estate
subsidiaries. In the current era of corporate restructuring and downsizing, many
companies have chosen to liquidate non-core businesses and real estate assets.
In addition, the Company believes that the trend from private to public
ownership is motivating many institutions to liquidate their privately-held real
estate portfolios. As a result, the Company believes that many opportunities
will exist to acquire real estate assets, real estate operating businesses or
interests in real estate joint ventures directly from corporations and
institutions. In some instances, the selling companies may have particular
objectives, such as the need to sell assets prior to the end of a fiscal quarter
or a desire to allow an operating partner to continue to participate in an
investment, which the Company expects to be able to accommodate. The Company
also believes that foreign institutions may become particularly active sellers
of domestic and foreign assets in the near future. The Company believes that it
will be able to capitalize on management's historically successful relationships
with a wide range of institutions and, therefore, have a competitive advantage
in accessing many of these portfolios. The Company believes that its experienced
management team and its expertise in managing large, complex portfolios may
allow the Company to (i) pursue property portfolios that other real estate
investment entities may view as too complex, and (ii) take advantage of the
opportunities presented by these portfolios that may have been inefficiently
managed.
 
    (iv) JOINT VENTURES AND STRATEGIC PARTNERSHIPS. The Company expects to enter
into, or acquire interests in, joint ventures or strategic partnerships as a way
to leverage both capital and expertise.
 
    (v) REAL ESTATE COMPANIES AND REAL ESTATE-RELATED BUSINESSES. As public
market ownership and consolidation continues in the real estate industry, the
Company expects to target investments in real estate companies and businesses
with a real estate component. Opportunities in this target area include public
and private companies, and generally fall into three types of companies: (a)
real estate ownership companies, including REITs and non-REIT ownership
companies, homebuilders and other development companies; (b) real estate service
companies, such as management or brokerage companies; and (c) businesses with a
strategic dependence on real estate. In particular, there may be opportunities
to
 
                                       48
<PAGE>
   
acquire controlling interests in certain small to mid-sized REITs that do not
trade at multiples as high as many other larger and better capitalized REITs.
The Company intends to invest in private placements of common stock or other
securities convertible into common stock. When the Company identifies strong
management teams and growth prospects, it may provide growth capital to such
companies and may recapitalize over-leveraged or other poorly-capitalized
companies. The Company believes that its experienced management will enhance
such companies' abilities to evaluate investment opportunities. The Company
expects to take advantage of the arbitrage between private and public market
pricing of real estate with its investments in this area. Conversely, when an
entity can be acquired for less than the value of its assets, the Company may
acquire control of such entity, whether directly (through the acquisition of a
controlling equity interest) or indirectly (through the acquisition of debt). To
supplement its efforts in this strategic area, the Company's management team
includes an individual with extensive experience in corporate private equity
investments.
    
 
   
    Although the Company expects that its primary emphasis will be on the
acquisition of the above-described categories of Real Estate-Related Assets,
future acquisitions also may include Other Assets. In making its investments,
the Company intends to conduct all of its investment activities in a manner
consistent with maintaining the status of BCP as a REIT for United States
federal income tax purposes. See "Federal Income Tax
Considerations--Requirements for Qualification." To the extent that the Company
believes that any of the above-described investments may add value to the
Company and the investment by stockholders in the Company, but are inconsistent
with maintaining the status of BCP as a REIT, such investments could be made by
the BCP Sister Corp. However, the Company's ability to fully utilize the BCP
Sister Corp. structure could be affected as a result of future legislation. See
"Risk Factors--Legal and Tax Risks--Adverse Impact of Future Legislation
Regarding REITs."
    
 
   
    The Company cannot anticipate with any certainty the percentage of the net
proceeds of the Original Offering, or its other assets or funds, that will be
invested in each category of Real Estate-Related Assets or Other Assets. The
Company has broad discretion in the manner in which it makes investments,
subject to its Investment Strategy. There can be no assurance that the Company
will be successful in its Investment Strategy. See "Risk Factors--Investment
Activity Risks--Appropriate Investments May Not Be Available and Investments of
Net Proceeds May Be Delayed."
    
 
INVESTMENT MANAGEMENT
 
    The Company intends to create value in, and realize value from, its
investments by identifying advantageous investment management strategies. The
senior management of the Company has extensive experience in a broad range of
aspects of real estate investment management, including financing, asset and
property management, development and dispositions.
 
   
    The Company's corporate office, located in Boston, is staffed by twenty-five
employees. The Company has regional offices located in Chicago and Los Angeles,
staffed by three and two employees, respectively. The Company intends to pursue
investments throughout the country. In addition, the Company intends to enhance
and extend its internal management resources through the relationships and
contacts with third-party property management and brokerage firms with
specialized geographic and property-type expertise and information that the
Company's management has developed as a result of its experience in the real
estate industry. Through its existing offices and these relationships, the
Company can gain a local presence in strategic markets and hands-on operational
knowledge of the assets underlying its investments, as well as better access to
proprietary transactions. The senior management of the Company has developed a
network of such parties and will expand such relationships as they pursue the
Company's Investment Strategy. Generally, the Company intends to structure
relationships with parties who will make meaningful equity investments and
provide incentives to its partners to ensure that the parties' interests are
aligned with the Company's, while the Company retains control over each
investment. See "Risk Factors-- Economic and Business Risks--Risks Related to
Growth Strategy."
    
 
                                       49
<PAGE>
    The Company intends to finance investments with the use of leverage in an
effort to maximize equity returns while allowing maximum flexibility and
maintaining an acceptable level of risk. As the real estate markets have
improved, the debt financing markets also have improved from the borrower's
perspective. Lenders are providing greater leverage at relatively lower cost
with greater structuring flexibility. The senior management of the Company has
established relationships in the lending community, being regular users of debt
financing and the Company expects to benefit from such individual lending
relationships. See "Management's Discussion and Analysis of Liquidity and
Capital Resources" and "Risk Factors-- Investment Activity Risks--Real Estate
Financing Risks."
 
   
    Generally, the Company intends to pursue a strategy of portfolio
diversification in terms of geographic location, property type, and investment
type. The Company believes that diversification is important to reducing
potential down-side risks. However, the Company will have no predetermined
limitations or targets for concentration of geographic location, property type,
or investment type. Instead, the Company plans to make investment decisions on a
case-by-case basis. See "Risk Factors--Investment Activity Risks--Appropriate
Investments May Not Be Available" and "Risk Factors--Investment Activity
Risks--Multi-Sector Investment Strategy."
    
 
THE BCP SISTER CORP.
 
   
    The Company anticipates that it may, from time to time, identify Assets that
it believes may be advantageous investments, but that may be inappropriate
(whether for REIT qualification, or other tax reasons) for investment, in whole
or in part, by a REIT, or which may otherwise be determined by the Company,
based on general prudent considerations, to be inappropriate, in whole or in
part, for investment by the Company. In order to permit stockholders to
participate in the economic benefits that may be associated with such
non-qualifying REIT Assets, the Company may, from time to time, cause the
Operating Partnership to form one or more subsidiary corporations, partnerships
or other entities (each, a "BCP Sister Corp."), which would not elect to be
taxed as a REIT. This structure has been employed by certain other REITs. The
Operating Partnership would initially contribute to the BCP Sister Corp. a
portion of its capital together with, on behalf of the Limited Partners, a pro
rata portion of the capital of the Operating Partnership allocable to the
Limited Partners' contributed capital, which will be sufficient to permit the
BCP Sister Corp. to make such initially identified investments, in exchange for
all of the issued and outstanding equity interests in the BCP Sister Corp. The
Operating Partnership would then distribute the equity interests pro rata to BCP
and the Limited Partners. BCP in turn would distribute the BCP Sister Corp.'s
equity interests to its stockholders in a taxable transaction. Concurrently with
the formation of the BCP Sister Corp., if any, or immediately subsequent
thereto, the BCP Sister Corp. will form an operating partnership (the "Sister
OP") upon substantially the same terms and conditions as the Operating
Partnership Agreement (including, without limitation, the terms respecting the
distribution of the Incentive Return to Beacon Capital Participation Plan).
Alternatively, the units of partnership of the Sister OP may be distributed
directly to the Limited Partners and the stockholders of BCP. Furthermore, to
the extent that certain synergies and efficiencies are possible between the
Company, the BCP Sister Corp. and the Sister OP, the Company intends to maximize
the opportunities presented by such synergies and efficiencies. For example, the
Company, the BCP Sister Corp. and the Sister OP may jointly acquire investments
in assets and businesses, such as hotels or health care facilities, where the
Company will acquire title to the underlying real property and lease such
property to the Sister OP, at market rents (including rents based upon a
percentage of gross revenues), while the Sister OP acquires and operates the
operating business. The Company anticipates that such synergies and efficiencies
will provide the Company with advantages in making investments over other
companies; however, no assurance can be made that the Company will be successful
in creating and implementing such synergies and efficiencies. See "Risk
Factors--Economic and Business Risks--Conflicts of Interest" and "Risk
Factors--Legal and Tax Risks--Adverse Impact of Future Legislation Regarding
REITs."
    
 
    The formation of the BCP Sister Corp. will permit stockholders of the
Company who retain common stock of the BCP Sister Corp. to participate in the
real estate operations of the Company (including
 
                                       50
<PAGE>
   
ownership of real property) and the BCP Sister Corp.'s operation of operating
businesses and other assets which may not otherwise be appropriate for a REIT.
The Company's principal focus will be to make real estate investments while any
BCP Sister Corp.'s principal function will be to serve as an operating company.
The operating activities and operating assets made available to the BCP Sister
Corp. by the Company are designed to provide BCP's stockholders with the
long-term benefits of ownership in an entity devoted to the conduct of operating
business activities in addition to their ownership interest in the Company. A
small number of REITs, operating under tax provisions that no longer are
available to newly-formed REITs, have their shares "paired" or "stapled" with
shares of a related operating company, and, therefore, cannot be owned or
transferred independently. It is the Company's intention that the Common Stock
of the Company and the equity interests of the BCP Sister Corp. will not be
paired or stapled, but rather will be structured as a "paper clip," a structure
designed to permit BCP to continue to qualify as a REIT. With respect to the
Common Stock of the Company and the equity interests of the BCP Sister Corp.
that may be owned and transferred, subject to applicable securities laws
restrictions, separately and independently of each other, the Company and the
BCP Sister Corp. will not necessarily provide a paired investment with the
Company on an ongoing basis. After the initial formation of the BCP Sister Corp.
and the distribution of its equity interests, the BCP Sister Corp. and the
Company will pursue independent sources of financing and, because the stock may
trade separately, may ultimately have differing ownership. See "The
Company--Certain Relationships; Conflicts of Interest," "Federal Income Tax
Considerations-- BCP Sister Corp." and "Risk Factors--Legal and Tax
Risks--Adverse Impact of Future Legislation Regarding REITs."
    
 
   
    To the extent that payments of rent may be made by the BCP Sister Corp. to
the Company, the Company will be required to monitor and comply with the
"related party tenant" provisions of the Code, which provide that payments made
under a lease will not constitute qualifying income for purposes of the REIT
requirements if the Company owns, directly or indirectly or pursuant to
attribution rules, 10% or more of the ownership interests in the relevant
lessee. The Aggregate Stock Ownership Limit is designed to prevent a stockholder
of the Company from owning an amount of shares that would cause the Company to
be treated as owning a BCP Sister Corp. However, any stockholder owning 10% or
more of the Company by reason of a waiver of the Aggregate Stock Ownership Limit
or the application of the Look-Through Ownership Limit may be required to reduce
its ownership percentage in the Company to below 10% in order to receive its pro
rata share of the distribution of the stock of the BCP Sister Corp., to ensure
that rents received by the REIT are not disqualified under the related party
tenant provisions.
    
 
   
    The Company's ability to fully utilize the BCP Sister Corp. structure could
be affected as a result of future legislation. In that regard, Congress recently
enacted, and the Clinton Administration signed into law, certain revenue
proposals as part of the Internal Revenue Service Restructuring and Reform Act
of 1998 that included, among other things, a freeze on the grandfathered status
of REITs that are "paired" or "stapled" with a related operating company. Unlike
such "paired" or "stapled" structures, the proposed BCP Sister Corp. structure
would be a "paper clip" structure in which interests in the BCP Sister Corp.
distributed to the Company's stockholders could be transferred independently
from the Company's Common Stock. Although such legislation does not affect the
"paper clip" structure, there can be no assurance that the recently enacted
legislation affecting the BCP Sister Corp. structure will not place legislative
or judicial scrutiny on the "paper clip" structure or that legislation adversely
affecting such a structure will not be proposed and enacted. See "Risk
Factors--Legal and Tax Risks--Adverse Impact of Future Legislation Regarding
REITs" and "Federal Income Tax Considerations--Impact of Proposed Legislation."
    
 
   
POLICIES WITH RESPECT TO CERTAIN OTHER ACTIVITIES.
    
 
   
    Although the Company has no specific policy with respect to such activities,
the Company does not presently anticipate that it will (i) underwrite the
securities of other unaffiliated issuers, or (ii) repurchase or reacquire its
shares or, other than through the redemption of Units in the Operating
Partnership, other securities.

(1) All information has been determined as of June 1, 1998. For the purposes of
    this table, a person is deemed to have "beneficial ownership" of the number
    of shares of Common Stock that person has the right to acquire pursuant to
    the exercise of stock options or redemption of Operating Partnership Units
    (assuming the Company elects to issue Common Stock rather than pay cash upon
    such redemption) held by such person or an affiliate of such person. Unless
    otherwise noted the address of each Beneficial Owner is: c/o Beacon Capital
    Partners, Inc., One Federal Street, 26th Floor, Boston, MA 02110.

           SELECTED HISTORICAL AND UNAUDITED PRO FORMA FINANCIAL DATA
    
 
   
    The selected historical financial data set forth below presents the
historical financial data of BCP as of June 30, 1998 and for the period from
January 21, 1998 (BCP's inception) through June 30, 1998. The selected pro forma
financial data of BCP set forth below assumes that BCP will qualify as a REIT.
The balance sheet data gives effect to (i) the acquisition of The Breunig
Portfolio, and (ii) the pending funding of an investment in a joint venture
known as The Sunnyvale Development as if these transactions had occurred as of
June 30, 1998. The income statement data gives effect to these transactions as
well as to (i) the acquisition of The Athenaeum Portfolio, and the subsequent
formation of a 50% joint venture, and (ii) the acquisition of Technology Square
and The Draper Building as if all transactions had occurred January 1, 1998. The
selected pro forma financial data are not necessarily indicative of what the
actual financial position or results of operations of BCP would have been as of
or for the period ended June 30, 1998, nor do they purport to be indicative of
the financial position or results of operations for future periods. The selected
financial data should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations," BCP's historical
financial statements and notes thereto and BCP's unaudited pro forma financial

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
    
 
   
OVERVIEW
    
 
   
    The following should be read in conjunction with the Consolidated Financial
Statements and notes thereto of BCP and the unaudited Pro Forma Condensed
Consolidated Financial Statements of BCP, each contained elsewhere herein. The
Consolidated Financial Statements of the Company include BCP and the Operating
Partnership, its majority-owned subsidiary. Due to its recent formation and the
relatively short period of operations presented in the Consolidated Financial
Statements, Management does not believe that the information presented therein
is indicative of expected financial performance.
    
 
   
LIQUIDITY AND CAPITAL RESOURCES
    
 
   
    Cash and cash equivalents were $323.9 million at March 31, 1998, which was
primarily the result of the Original Offering on March 20, 1998. Cash and cash
equivalents were $199.9 million at June 30, 1998. The decrease primarily
resulted from the acquisitions of The Athenaeum Portfolio, Technology Square and
The Draper Building and loan repayments to the Company founders offset by the
proceeds received from the exercise of the underwriter's over-allotment option,
the issuance of Operating Partnership Units and cash flow from operations.
    
 
   
SHORT AND LONG TERM LIQUIDITY
    
 
   
    The Company has considered its short-term liquidity needs and the adequacy
of expected liquidity sources to meet these needs. The Company believes that its
principal short-term liquidity needs are to fund normal recurring expenses, debt
service requirements and the minimum distribution required to maintain the
Company's REIT qualification under the Internal Revenue Code of 1986, as
amended. The Company believes that these needs will be funded from cash flows
provided by operating activities.
    
 
   
    The Company expects to meet long-term liquidity requirements for the costs
of additional development, real estate and real estate related investments,
scheduled debt maturities, major renovations, expansions and other non-recurring
capital improvements through long-term secured and unsecured indebtedness and
the issuance of additional Operating Partnership Units and equity securities.
    
 
   
FINANCING ACTIVITIES
    
 
   
    BCP was incorporated on January 21, 1998 as a Massachusetts corporation and
was initially capitalized through loans from the Company founders, Messrs.
Leventhal and Fortin, in the amount of $3.6 million. On May 1, 1998, Messrs.
Leventhal and Fortin were repaid.
    
 
   
    On March 20, 1998, the Company completed an initial private offering
("Original Offering") issuing 17,630,769 shares of Common Stock with proceeds,
net of offering costs, of $323.1 million. On April 3, 1998 and April 13, 1998,
through the exercise of the underwriter's over-allotment option, 3,613,163
additional shares were issued with proceeds, net of offering costs, of $66.6
million.
    
 
   
    In connection with the re-incorporation of BCP as a Maryland corporation,
BCP established Beacon Capital Partners, L.P. (the "Operating Partnership"). As
contemplated in the Original Offering, an entity controlled by Messrs. Leventhal
and Fortin was to contribute $4.2 million to the Operating Partnership for a 1%
limited partnership interest. In order to comply with the requirements of ERISA,
such contribution could only be made subsequent to the closing of the first real
estate transaction of the Company. The $4.2 million contribution was made on May
4, 1998.

INVESTING ACTIVITIES
    
 
   
    On May 1, 1998, the Company acquired The Athenaeum Portfolio, an eleven
building, 970,000 square foot mixed-use portfolio located in Cambridge, MA. The
aggregate consideration for the properties was $195 million, consisting of
approximately $125.9 million in cash and the assumption of approximately $69
million of first mortgage debt. The Company used proceeds from the Original
Offering for the cash portion of the acquisition. Subsequent to the closing of
the transaction, the Company completed the formation of a joint venture with PW
Acquisitions IX, LLC, an affiliate of PaineWebber, in which both parties hold a
50% interest in the master limited liability company that controls the two
limited liability companies that hold title to The Athenaeum Portfolio.
    
 
   
    On June 24, 1998, the Company acquired a four building complex known as
Technology Square and an adjacent building known as The Draper Building. The
properties are located in Cambridge, MA and consist of approximately 1,026,000
square feet. The aggregate consideration for the properties was $123 million,
consisting of $71.6 million in cash and the issuance of $51.4 million of units
of limited partnership interest in the Operating Partnership. The Company used
proceeds from the Original Offering for the cash portion of the acquisition.
    
 
   
    On July 1, 1998, the Company acquired a 1,335,000 square foot portfolio of
seven office properties and seven research & development (R&D) properties
located in suburban Dallas, TX. The aggregate consideration for the properties
was $91.2 million, consisting of approximately $69.4 million in cash and the
assumption of approximately $21.8 million of first mortgage debt. The Company
used proceeds from the Original Offering for the cash portion of the
acquisition.
    
 
   
    On August 9, 1998, the Company entered into a joint venture agreement with
Mathilda Partners LLC, an affiliate of Menlo Equities, a California based
developer. This venture entered into a contract to acquire a twelve-acre site on
Mathilda Avenue in Sunnyvale, California, on which the venture plans to
construct two four-story Class A office buildings with surface parking. Although
not finalized, the development budget for 267,000 square feet is anticipated to
be approximately $57 million, of which 40% will be funded from cash
contributions and the balance will be financed with a construction loan.
    
 
   
CAPITALIZATION
    
 
   
    Currently, the Company's total consolidated mortgage debt is approximately
$21.6 million and its total consolidated mortgage debt plus its proportionate
share of total unconsolidated mortgage debt is approximately $56.0 million. The
Company's current consolidated mortgage indebtedness has a weighted average rate
of 8.22%, with maturities ranging from 1999 through 2022, and is secured by the
properties. The Company's proportionate share of its current total
unconsolidated mortgage debt consists of approximately $56.0 million with a rate
of 8.485% on The Athenaeum Portfolio (in which the Company holds a 50% interest
in the limited liability company that controls the two limited liability
companies that hold title to this portfolio). The weighted average rate of the
Company's consolidated and unconsolidated mortgage debt is 8.38%.
    
 
   
RESULTS OF OPERATIONS
    
 
   
    For the period January 21, 1998 through March 31, 1998, the Company had a
net loss of $0.4 million consisting primarily of $0.6 million of interest income
earned on the investment of the net proceeds of the Original Offering offset by
general and administrative expenses of approximately $1 million.
    
 
   
    For the period January 21, 1998 through June 30, 1998, the Company had net
income of approximately $4 million generated from total revenues of $6.8 million
offset by expenses of $2.8 million. The growth in total revenues is primarily a
result of interest income of $5.6 million, The Athenaeum Portfolio equity
earnings of $1 million, and Technology Square and The Draper Building rental
income of $0.2 million. The change in expenses is primarily a result of
increased corporate general and administrative
    
 
                                       57
<PAGE>
   
expenses of $2.6 million and Technology Square and The Draper Building property
expenses and real estate taxes of $0.1 million.
    
 
   
    On a pro forma basis, for the six months ended June 30, 1998, the Company
had net income of approximately $4.4 million generated from total revenues of
$16 million offset by expenses of $11 million (and minority interest in
Operating Partnership of $0.6 million). Total revenues consist of Technology
Square and The Draper Building and The Breunig Portfolio rental income of $11.2
million, interest income of $2.3 million, The Athenaeum Portfolio equity
earnings of $2.3 million and other income of $0.2 million. Expenses primarily

YEAR 2000 COMPLIANCE
    
 
   
    BCP's Year 2000 initiative is being managed by BCP to minimize any adverse
effect on BCP's business operations and is scheduled to be completed in 1999.
While BCP believes its planning and efforts are adequate to address its Year
2000 concerns, there can be no guarantee that the systems of other companies on
which BCP's systems and operations rely will be converted on a timely basis and
will not have a material effect on BCP. The cost of the Year 2000 initiatives is
not expected to be material to BCP's results of operations or financial
position.

                           DESCRIPTION OF SECURITIES
 
    The following description of the terms of the stock of BCP does not purport
to be complete and is subject to and qualified in its entirety by reference to
the Charter and the Bylaws, copies of which are available upon request to the
Company. See "Certain Provisions of Maryland Law and of BCP's Charter and
Bylaws."
 
GENERAL
 
   
    The Charter provides that BCP has the authority to issue up to 950,000,000
shares of stock, consisting of 500,000,000 shares of Common Stock, $.01 par
value per share, 250,000,000 shares of excess stock, $.01 par value per share
("Excess Stock") and 200,000,000 shares of preferred stock, $.01 par value per
share ("Preferred Stock"). As of August 1, 1998, 20,973,932 shares of Common
Stock are issued and outstanding and no shares of Excess Stock or Preferred
Stock are issued and outstanding. Under Maryland law, stockholders generally are
not liable for the corporation's debts or obligations.
    
 
COMMON STOCK
 
    Subject to the preferential rights of any other class or series of stock and
to the provisions of the Charter regarding Excess Stock, holders of shares of
Common Stock are entitled to receive dividends on such Common Stock if, as and
when authorized and declared by the Board of Directors of BCP out of assets
legally available therefor and to share ratably in the assets of BCP legally
available for distribution to its stockholders in the event of its liquidation,
dissolution or winding-up after payment of or adequate provision for all known
debts and liabilities of BCP.
 
    Subject to the provisions of the Charter regarding Excess Stock, each
outstanding share of Common Stock entitles the holder to one vote on all matters
submitted to a vote of stockholders, including the election of directors, except
as otherwise required by law and except as provided with respect to any other
class or series of stock, the holders of such shares of Common Stock will
possess exclusive voting power. There is no cumulative voting in the election of
directors, which means that the holders of a majority of the outstanding shares
of Common Stock can elect all of the directors then standing for election and
the holders of the remaining shares of Common Stock will not be able to elect
any Directors.
 
    Holders of shares of Common Stock have no preference, conversion, exchange,
sinking fund, redemption or appraisal rights (except as provided by Maryland
law) and have no preemptive rights to subscribe for any securities of the
Company. Subject to the provisions of the Charter regarding Excess Stock, shares
of Common Stock will have equal dividend, liquidation and other rights.
 
   
    Under the MGCL, a Maryland corporation generally cannot dissolve, amend its
charter, merge, sell all or substantially all of its assets, engage in a share
exchange or engage in similar transactions outside the ordinary course of
business unless approved by the affirmative vote of stockholders holding at
least two thirds of the shares entitled to vote on the matter unless a different
percentage (but not less than a majority of all of the votes entitled to be cast
on the matter) is set forth in the corporation's charter. The Charter of BCP
does not provide for a different percentage in such situations, except for
certain amendments to the Charter. See "Certain Provisions of Maryland Law and
BCP's Charter and Bylaws-- Amendment of Charter and Bylaws."
    
 
PREFERRED STOCK
 
    The Charter authorizes the Board of Directors to classify any unissued
shares of Preferred Stock and to reclassify any previously classified but
unissued shares of Preferred Stock of any series, as authorized by the Board of
Directors. Prior to issuance of shares of each class or series, the Board is
required by the MGCL and the Charter to fix, subject to the provisions of the
Charter regarding Excess Stock, the preferences, conversion or other rights,
voting powers, restrictions, limitations as to dividends or other
 
                                       59
<PAGE>
distributions, qualifications and terms or conditions of redemption for each
such class or series. Such rights, powers, restrictions and limitations could
include the right to receive specified dividend payments and payments on
liquidation prior to any such payments being made to the holders of some, or a
majority, of the Common Stock. The Board of Directors could authorize the
issuance of Preferred Stock with terms and conditions that could have the effect
of discouraging a takeover or any other transaction that holders of Common Stock
might believe to be in their best interests or in which holders of some, or a
majority, of the Common Stock might receive a premium for their shares over the
then current market price of such shares. As of the date hereof, no shares of
Preferred Stock are outstanding and BCP has no present plans to issue any
Preferred Stock.
 
POWER TO ISSUE ADDITIONAL SHARES OF COMMON STOCK AND PREFERRED STOCK
 
    BCP believes that the power of the Board of Directors to issue additional
authorized but unissued shares of Common Stock or Preferred Stock and to
classify or reclassify unissued shares of Common or Preferred Stock and
thereafter to cause BCP to issue such classified or reclassified shares of stock
will provide BCP with increased flexibility in structuring possible future
financings and acquisitions and in meeting other needs which might arise. The
additional classes or series, as well as the Common Stock, will be available for
issuance without further action by BCP's stockholders, unless such action is
required by applicable law or the rules of any stock exchange or automated
quotation system on which BCP's securities may be listed or traded. Although the
Board of Directors has no intention at the present time of doing so, it could
authorize BCP to issue a class or series that could, depending upon the terms of
such class or series, delay, defer or prevent a transaction or a change in
control of BCP that might involve a premium price for holders of Common Stock or
otherwise be in their best interest.
 
DIVIDEND REINVESTMENT PLAN
 
    BCP may implement a dividend reinvestment plan whereby stockholders may
automatically reinvest their dividends in the Common Stock. Details about any
such plan would be sent to BCP's stockholders following adoption thereof by the
Board of Directors.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is EquiServe (the
"Transfer Agent") in Boston, Massachusetts.
 
TRANSFER RESTRICTIONS
 
    RESTRICTIONS UNDER CHARTER.  In order for the Company to qualify as a REIT
under the Code, among other things, not more than 50% in value of its
outstanding stock may be owned, directly or indirectly, by five or fewer
individuals (defined in the Code to include certain entities) during the last
half of a taxable year (other than the first year for which an election to be a
REIT has been made) (the "Five or Fewer Requirement"), and such shares of
capital stock must be beneficially owned by 100 or more persons during at least
335 days of a taxable year of 12 months (other than the first year for which an
election to be a REIT has been made) or during a proportionate part of a shorter
taxable year. See "Federal Income Tax Considerations." In order to protect the
Company against the risk of losing its status as a REIT and to otherwise protect
the Company from the consequences of a concentration of ownership among its
stockholders, the Charter, subject to certain exceptions, provides that no
single person (which may include certain "groups" of persons) may "beneficially
own" more than 9.8% (the "Aggregate Stock Ownership Limit") of the aggregate
number of outstanding shares of any class or series of stock; provided, however,
that certain mutual funds registered under the Investment Company Act of 1940
and certain other widely-held entities (other than pension plans as described in
Section 401(a) of the Code) ("Look-Through Entities") may "beneficially own" no
more than 15% (the "Look-Through Ownership Limit"). Under the Charter, a person
generally "beneficially owns" shares if (i) such person has direct ownership of
such
 
                                       60
<PAGE>
shares, (ii) such person has indirect ownership of such shares taking into
account the constructive ownership rules of Section 544 of the Code, as modified
by Section 856(h)(1)(B) of the Code, or (iii) such person would be deemed to
"beneficially own" such shares pursuant to Rule 13d-3 under the Exchange Act.
Any transfer of shares of stock or of any security convertible into shares of
stock that would create a direct or indirect ownership of shares of stock in
excess of the Aggregate Stock Ownership Limit or the Look-Through Ownership
Limit, as applicable, or that would result in the disqualification of the
Company as a REIT, including any transfer that results in the shares of stock
being owned by fewer than 100 persons or results in the Company being "closely
held" within the meaning of Section 856(h) of the Code or results in the Company
constructively owning 10% or more of the ownership interests in a tenant of the
Company within the meaning of Section 318 of the Code as modified by Section
856(d)(5) of the Code, shall be null and void, and the intended transferee will
acquire no rights to the shares of stock. The foregoing restrictions on
transferability and ownership will not apply if the Board of Directors
determines that it is no longer in the best interests of the Company to attempt
to qualify, or to continue to qualify, as a REIT. The Board of Directors, upon
receipt of a ruling from the Service or an opinion of counsel or other evidence
or undertakings acceptable to it, may, in its sole discretion, waive the
Aggregate Stock Ownership Limit and the Look-Through Ownership Limit if evidence
satisfactory to the Board of Directors is presented that the changes in
ownership will not jeopardize the Company's REIT status or cause the Company to
be a "pension-held REIT" for federal income tax purposes and the Board of
Directors otherwise decides that such action is in the best interest of the
Company.
 
    If any purported transfer of stock of the Company or any other event would
otherwise result in any person violating the Aggregate Stock Ownership Limit or
the Look-Through Ownership Limit, as applicable, or the Charter, then any such
purported transfer will be void and of no force or effect with respect to the
purported transferee (the "Prohibited Transferee") as to that number of shares
in excess of the applicable limit and the Prohibited Transferee shall acquire no
right or interest (or, in the case of any event other than a purported transfer,
the person or entity holding record title to any such shares in excess of the
applicable limit (the "Prohibited Owner") shall cease to own any right or
interest) in such excess shares. Any such excess shares described above will be
converted automatically into an equal number of shares of Excess Stock (the
"Excess Shares") and transferred automatically, by operation of law, to a trust,
the beneficiary of which will be a qualified charitable organization selected by
the Company (the "Beneficiary"). Such automatic transfer shall be deemed to be
effective as of the close of business on the Trading Day (as defined in the
Charter) prior to the date of such violative transfer. As soon as practical
after the transfer of shares to the trust but in an orderly fashion so as not to
materially adversely affect the trading price of the Common Stock, the trustee
of the trust (who shall be designated by the Company and be unaffiliated with
the Company and any Prohibited Transferee or Prohibited Owner) will be required
to sell such Excess Shares to a person or entity who could own such shares
without violating the applicable Limit, and distribute to the Prohibited
Transferee an amount equal to the lesser of the price paid by the Prohibited
Transferee for such Excess Shares or the sales proceeds received by the trust
for such Excess Shares. In the case of any Excess Shares resulting from any
event other than a transfer, or from a transfer for no consideration (such as a
gift or devise), the trustee will be required to sell such Excess Shares to a
qualified person or entity and distribute to the Prohibited Owner an amount
equal to the lesser of the fair market value of such Excess Shares as of the
date of such event or the sales proceeds received by the trust for such Excess
Shares. In either case, any proceeds in excess of the amount distributable to
the Prohibited Transferee or Prohibited Owner, as applicable, will be
distributed to the Beneficiary. Prior to a sale of any such Excess Shares by the
trust, the trustee will be entitled to receive in trust for the Beneficiary, all
dividends and other distributions paid by the Company with respect to such
Excess Shares.
 
    The Prohibited Owner with respect to such Excess Shares shall repay to the
trust the amount of any dividends or distributions received by it that (i) are
attributable to any shares of stock that have been converted into Excess Shares
and (ii) were distributed by the Company to stockholders of record on a record
date which was on or after the date that such shares were converted into Excess
Shares. Each Excess Share shall entitle the holder to no voting rights other
than those voting rights which accompany a
 
                                       61
<PAGE>
class of stock under Maryland law. The trustee, as record holder of the Excess
Shares, shall be entitled to vote all Excess Shares. Any vote by a Prohibited
Owner as a purported holder of shares of stock prior to the discovery by the
Company that such shares of stock have been converted into Excess Shares shall,
subject to applicable law, (i) be rescinded and shall be void AB INITIO with
respect to such Excess Shares and (ii) be recast in accordance with the desires
of the trustee acting for the benefit of the Beneficiary; provided, however,
that if the Company has already taken irreversible corporate action, then the
trustee shall not have the authority to rescind and recast such vote.
 
    In addition, shares of stock of the Company held in the trust shall be
deemed to have been offered for sale to the Company, or its designee, at a price
per share equal to the lesser of (i) the price per share in the transaction that
resulted in such transfer to the trust (or, in the case of a devise or gift, the
market price at the time of such devise or gift) and (ii) the market price on
the date the Company, or its designee, accepts such offer. The Company shall
have the right to accept such offer for a period of 90 days following the later
of (a) the date of the event which resulted in such shares of Excess Stock or
(b) the date the Board of Directors first determined that the event resulting in
the shares of Excess Stock occurred, if the Company does not receive notice of
such event. Upon such a sale to the Company, the interest of the Beneficiary in
the shares sold shall terminate and the trustee shall distribute the net
proceeds of the sale to the Prohibited Owner.
 
    Each stockholder shall upon demand be required to disclose to the Company in
writing any information with respect to the direct, indirect and constructive
ownership of capital stock as the Board of Directors deems necessary to comply
with the provisions of the Code applicable to REITs, to comply with the
requirements of any taxing authority or governmental agency or to determine any
such compliance.
 
    The above-described ownership limits may have the effect of precluding
acquisition of control of the Company.
 
REGISTRATION RIGHTS
 
    The Selling Stockholders of the Common Stock are entitled to the benefits of
a Registration Rights Agreement between the Company and the Initial Purchaser in
the Original offering (the "Registration Rights Agreement"). Pursuant to the
Registration Rights Agreement, the Company has agreed for the benefit of the
holders of the Common Stock that it will from time to time, at its expense, (i)
promptly, but in any event within 90 days after the date of issuance of the
Common Stock, file a shelf registration statement (the "Shelf Registration
Statement") with the Commission with respect to resales of the Common Stock,
(ii) use its best efforts to cause such Shelf Registration Statement to be
declared effective by the Commission as promptly as practicable and (iii) use
its best efforts to maintain such Shelf Registration Statement continuously
effective under the Securities Act, until the date (the "Expiration Date") which
is the earliest of the dates described in the following clauses (a), (b) and
(c): (a) the second annual anniversary of the latest date of original issuance
of the Common Stock, (b) such time as all Common Stock covered by the Shelf
Registration Statement has been sold pursuant to the Shelf Registration
Statement, transferred pursuant to Rule 144 under the Securities Act or
otherwise transferred in a manner that results in a new security not subject to
transfer restrictions under the Securities Act being delivered, and (c) such
time as, in the opinion of counsel, all of the Common Stock held by
nonaffiliates of the Company and covered by the Shelf Registration Statement are
eligible for resale pursuant to Rule 144(k) (or any successor or analogous rule)
under the Securities Act and the legend described under "Notice to Investors"
has been removed from such Common Stock. The Registration Statement of which
this Prospectus forms a part has been filed pursuant to the foregoing provisions
of the Registration Rights Agreement.
 
    Notwithstanding the foregoing, the Company will be permitted to suspend the
use, from time to time, of this prospectus that is part of the Shelf
Registration Statement for periods (any such period hereinafter referred to as a
"blackout period"), if the Board of Directors of the Company shall have
determined in
 
                                       62
<PAGE>
good faith that it is in the best interests of the Company to suspend such use
and the Company provides the Selling Stockholders with written notice of such
suspension.
 
    A Selling Stockholder that sells Common Stock pursuant to the Shelf
Registration Statement, including through the use of this Prospectus, generally
will be required to be named as a selling security holder in the related
prospectus and to deliver a prospectus to purchasers, will be subject to certain
of the civil liability provisions under the Securities Act in connection with
such sales and will be bound by the provisions of the Registration Rights
Agreement that are applicable to such a holder (including certain
indemnification rights and obligations). In addition, each holder of Common
Stock may be required to deliver information to be used in connection with the
Shelf Registration Statement in order to have such holder's Common Stock
included in the Shelf Registration Statement and to benefit from the provisions
of the succeeding paragraph.
 
   
    Each Common Stock certificate contains a legend to the effect that the
holder thereof, by its acceptance thereof, will be deemed to have agreed to be
bound by the provisions of the Registration Rights Agreement. In that regard,
each holder is deemed to have agreed that, upon receipt of notice from the
Company of the occurrence of any event which makes a statement in this
prospectus untrue in any material respect or which requires the making of any
changes in such prospectus in order to make the statements therein not
misleading, or of certain other events specified in the Registration Rights
Agreement, such holder will suspend the sale of Common Stock pursuant to this
prospectus until the Company has amended or supplemented such prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented prospectus to such holder or the Company has given notice that the
sale of the Common Stock may be resumed.
    
 
   
    The Company has agreed, pursuant to a registration rights agreement with
Luddite Associates, a partnership owned by The Prudential Insurance Company of
America and its affiliates, to register, on any four occasions after September
1, 1999, at the request of Luddite Associates (or in certain other
circumstances), the shares of Common Stock which may be issued by the Company
upon the redemption of 2,528,296 Units held by Luddite Associates. The Company
will bear all expenses incident to the registration of securities under this
agreement, except that such expenses shall not include any underwriting
discounts or commissions, or transfer taxes, if any, relating to such shares.

                     CERTAIN PROVISIONS OF MARYLAND LAW AND
                          OF BCP'S CHARTER AND BYLAWS
 
    THE FOLLOWING SUMMARY OF CERTAIN PROVISIONS OF MARYLAND LAW AND OF THE
CHARTER AND BYLAWS OF BCP DOES NOT PURPORT TO BE COMPLETE AND IS SUBJECT TO AND
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO MARYLAND LAW AND TO THE CHARTER AND
BYLAWS OF BCP.
 
    The Charter and the Bylaws of BCP contain certain provisions that could make
more difficult the acquisition of the Company by means of a tender offer, a
proxy contest or otherwise. These provisions may have the effect of delaying,
deterring or preventing certain types of coercive takeover practices and
inadequate takeover bids and to encourage persons seeking to acquire control of
the Company to negotiate first with the Board of Directors. The Company believes
that the benefits of these provisions outweigh the potential disadvantages of
discouraging such proposals because, among other things, negotiation of such
proposals might result in an improvement of their terms.
 
AMENDMENT OF CHARTER AND BYLAWS
 
    BCP's Charter may be amended only by the affirmative vote of the holders of
a majority of all of the votes entitled to be cast on the matter, (or, if less
than 75% of the Directors then in office approve the amendment, by the
affirmative vote of holders of two-thirds of all votes entitled to be cast on
the matter) except that amendments dealing with certain articles of the Charter
(for example, articles relating to stockholder action; the powers, election of,
removal of and classification of directors; limitation of liability; and
amendment of the Charter) shall require the affirmative vote of not less than
seventy-five percent of the outstanding votes entitled to be cast on the matter.
Unless otherwise required by law, the Board of Directors may amend BCP's Bylaws
by the affirmative vote of a majority of the Directors then in office.
 
DISSOLUTION OF THE COMPANY
 
    The MGCL permits the dissolution of the Company by (i) the affirmative vote
of a majority of the entire Board of Directors declaring such dissolution to be
advisable and directing that the proposed dissolution be submitted for
consideration at an annual or special meeting of stockholders, and (ii) upon
proper notice, stockholder approval by the affirmative vote of two-thirds of the
votes entitled to be cast on the matter.
 
MEETINGS OF STOCKHOLDERS
 
    Under BCP's Bylaws, annual meetings of stockholders shall be held at such
date and time as determined by the Board of Directors, the Chairman of the Board
or the President. The Bylaws establish an advance notice procedure for
stockholders to make nominations of candidates for directors or bring other
business before an annual meeting of stockholders. Special meetings of
stockholders may be called by a majority of the Directors then in office or by
stockholders holding not less than a majority of the outstanding stock of BCP
entitled to vote at the meeting and only matters set forth in the notice of the
meeting may be considered and acted upon at such a meeting.
 
THE BOARD OF DIRECTORS
 
    BCP's Charter provides that the Board of Directors shall initially consist
of five Directors and thereafter the number of Directors of the Company may be
established by the Board of Directors but may not be fewer than the minimum
number required by the MGCL nor more than nine. Subject to the rights of the
holders of any series of Preferred Stock to elect Directors and to fill
vacancies in the Board of Directors relating thereto, any vacancy will be
filled, including any vacancy created by an increase in the number of Directors,
at any regular meeting or at any special meeting called for the purpose, by a
majority of the remaining Directors. Pursuant to the terms of the Charter, the
Directors are divided into three classes. One class will hold office initially
for a term expiring at the annual meeting of stockholders to be
 
                                       64
<PAGE>
held in 1999, another class will hold office initially for a term expiring at
the annual meeting of stockholders to be held in 2000 and the third class will
hold office initially for a term expiring in 2001. As the term of each class
expires, Directors in that class will be elected for a term of three years and
until their successors are duly elected and qualified. The use of a classified
board may render more difficult a change in control of the Company or removal of
incumbent management. The Charter provides that a Director may be removed from
office (a) only with cause and (b) only by the affirmative vote of the holders
of at least 75% of the shares entitled to vote at a meeting of stockholders
called for that purpose. The Company believes, however, that classification of
the Board of Directors will help to assure the continuity and stability of its
business strategies and policies.
 
    The Charter provides that the affirmative vote of more than 75% of the
Directors then in office is required to approve certain transactions or actions
of the Board, including a change of control (as defined in the Charter) of the
Company or of the Operating Partnership, any amendment to the Operating
Partnership Agreement, any waiver of the limitations on ownership contained in
the Charter, any merger, consolidation or sale of all or substantially all of
the assets of the Company or the Operating Partnership, certain issuances of
equity securities by the Company or the termination of the Company's status as a
REIT. See "Operating Partnership Agreement."
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
    The Charter limits the liability of the Board of Directors and officers to
the Company to the fullest extent permitted from time to time by Maryland law.
The MGCL permits a corporation to include in its charter a provision limiting
the liability of directors and officers to the corporation or its stockholders
for money damages, except (i) to the extent that it is proved that the director
or officer actually received an improper benefit or profit in money, property or
services or (ii) if a judgment or other final adjudication is entered in a
proceeding based on a finding that the director's or officer's action or failure
to act was the result of active and deliberate dishonesty and was material to
the cause of action adjudicated in the proceeding. This provision does not limit
the ability of BCP or its stockholders to obtain other relief, such as an
injunction or a rescission.
 
    The Charter of the Company authorizes it, to the maximum extent permitted by
Maryland law, to obligate itself to indemnify and to pay or reimburse reasonable
expenses in advance of final disposition of a proceeding to (a) any present or
former director or officer or (b) any individual who, while a director of the
Company and at the request of the Company, serves or has served another
corporation, REIT, partnership, joint venture, trust, employee benefit plan or
any other enterprise as a director, officer, partner or trustee of such
corporation, REIT, partnership, joint venture, trust, employee benefit plan or
other enterprise from and against any claim or liability to which such person
may become subject or which such person may incur by reason of his or her status
as a present or former director or officer of the Company. The Bylaws of the
Company obligate it, to the maximum extent permitted by Maryland law, to
indemnify and to pay or reimburse reasonable expenses in advance of final
disposition of a proceeding to (a) any present or former director or officer who
is made a party to the proceeding by reason of his service in that capacity or
(b) any individual who, while a director of the Company and at the request of
the Company, serves or has served another corporation, REIT, partnership, joint
venture, trust, employee benefit plan or any other enterprise as a director,
officer, partner or trustee of such corporation, REIT, partnership, joint
venture, trust, employee benefit plan or other enterprise and who is made a
party to the proceeding by reason of his service in that capacity. The Charter
and Bylaws also permit the Company to indemnify and advance expenses to any
person who served a predecessor of the Company in any of the capacities
described above and to any employee or agent of the Company or a predecessor of
the Company.
 
    The MGCL requires a corporation (unless its charter provides otherwise,
which the Company's Charter does not) to indemnify a director or officer who has
been successful, on the merits or otherwise, in the defense of any proceeding to
which he is made a party by reason of his service in that capacity. The
 
                                       65
<PAGE>
MGCL permits a corporation to indemnify its directors, officers and certain
other parties against judgments, penalties, fines, settlements and reasonable
expenses actually incurred by them in connection with any proceeding to which
they may be made a party by reason of their service to or at the request of the
corporation, unless it is established that (a) the act or omission of the
indemnified party was material to the matter giving rise to the proceeding and
(i) the act or omission was committed in bad faith or (ii) the act or omission
was the result of active and deliberate dishonesty, (b) the indemnified party
actually received an improper personal benefit in money, property or services or
(c) in the case of any criminal proceeding, the indemnified party had reasonable
cause to believe that the act or omission was unlawful. However, under the MGCL,
a Maryland corporation may not indemnify for an adverse judgment in a suit by or
in the right of the corporation or for a judgment of liability on the basis that
personal benefit was improperly received, unless in either case a court orders
indemnification and then only for expenses. In addition, the MGCL permits a
corporation to advance reasonable expenses to a director or officer upon the
corporation's receipt of (a) a written affirmation by the director or officer of
his good faith belief that he has met the standard of conduct necessary for
indemnification by the corporation and (b) a written undertaking by him or on
his behalf to repay the amount paid or reimbursed by the corporation if it shall
ultimately be determined that the standard of conduct was not met.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in the
opinion of the SEC such indemnification is against public policy as expressed in
the Securities Act and is therefore unenforceable.
 
INDEMNIFICATION AGREEMENTS
 
    The Company has entered into indemnification agreements with each of its
Directors and executive officers which require, among other things, that the
Company indemnify its Directors and executive officers to the fullest extent
permitted by law and advance to the Directors and executive officers all related
expenses, subject to reimbursement if it is subsequently determined that
indemnification is not permitted. Under these agreements, the Company must also
indemnify and advance all expenses incurred by Directors and executive officers
seeking to enforce their rights under the indemnification agreements and may
cover Directors and executive officers under the Company's Directors' and
officers' liability insurance. Although the form of indemnification agreement
offers substantially the same scope of coverage afforded by law, it provides
greater assurance to Directors and executive officers that indemnification will
be available, because, as a contract, it cannot be modified unilaterally in the
future by the Board of Directors or the stockholders to eliminate the rights it
provides.

    Under the MGCL, certain "business combinations" (including a merger,
consolidation, share exchange or, in certain circumstances, an asset transfer or
issuance or reclassification of equity securities) between a Maryland
corporation and any person who beneficially owns 10% or more of the voting power
of the corporation's shares or an affiliate of the corporation who, at any time
within the two-year period prior to the date in question, was the beneficial
owner of 10% or more of the voting power of the then-outstanding voting stock of
the corporation (an "Interested Stockholder") or an affiliate of such an
Interested Stockholder are prohibited for five years after the most recent date
on which the Interested Stockholder becomes an Interested Stockholder.
Thereafter, any such business combination must be recommended by the board of
directors of such corporation and approved by the affirmative vote of at least
(a) 80% of the votes entitled to be cast by holders of outstanding shares of
voting stock of the corporation and (b) two-thirds of the votes entitled to be
cast by holders of outstanding voting stock of the corporation other than shares
held by the Interested Stockholder with whom (or with whose affiliate) the
business combination is to be effected, unless, among other conditions, the
corporation's common stockholders receive a minimum price (as defined in the
MGCL) for their shares and the consideration is
 
                                       66
<PAGE>
received in cash or in the same form as previously paid by the Interested
Stockholder for its shares. These provisions of the MGCL do not apply, however,
to business combinations that are approved or exempted by the board of directors
of the corporation prior to the time that the Interested Stockholder becomes an
Interested Stockholder. The Charter exempts from the Maryland statute any
business combination with Alan M. Leventhal or Lionel P. Fortin, or current or
future affiliates, associates or other persons acting in concert as a group with
either of Messrs. Leventhal or Fortin.
 
CONTROL SHARE ACQUISITIONS
 
    The MGCL provides that "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the matter,
excluding shares of stock owned by the acquiror, by officers or by directors who
are employees of the corporation. "Control shares" are voting shares of stock
which, if aggregated with all other shares of stock previously acquired by the
acquiror or in respect of which the acquiror is able to exercise or direct the
exercise of voting power (except solely by virtue of a revocable proxy), would
entitle the acquiror to exercise voting power in electing directors within one
of the following ranges of voting power: (i) one-fifth or more but less than
one-third, (ii) one-third or more but less than a majority, or (iii) a majority
or more of all voting power. Control shares do not include shares the acquiring
person is then entitled to vote as a result of having previously obtained
stockholder approval. A "control share acquisition" means the acquisition of
control shares, subject to certain exceptions.
 
    A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain conditions (including an undertaking to pay expenses),
may compel the board of directors of the corporation to call a special meeting
of stockholders to be held within 50 days of demand to consider the voting
rights of the shares. If no request for a meeting is made, the corporation may
itself present the question at any stockholders meeting.
 
    If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as required by the statute, then,
subject to certain conditions and limitations, the corporation may redeem any or
all of the control shares (except those for which voting rights have previously
been approved) for fair value determined, without regard to the absence of
voting rights for the control shares, as of the date of the last control share
acquisition by the acquiror or of any meeting of stockholders at which the
voting rights of such shares are considered and not approved. If voting rights
for control shares are approved at a stockholders meeting and the acquiror
becomes entitled to vote a majority of the shares entitled to vote, all other
stockholders may exercise appraisal rights. The fair value of the shares as
determined for purposes of such appraisal rights may not be less than the
highest price per share paid by the acquiror in the control share acquisition.
 
   
    The control share acquisition statute does not apply (a) to shares acquired
in a merger, consolidation or share exchange if the corporation is a party to
the transaction or (b) to acquisitions approved or exempted by the charter or
bylaws of the corporation. The Charter exempts from the control share
acquisition statute the purchases of Common Stock on the Closing Date of the
Original Offering and any future transactions which would otherwise be subject
to the statute by Alan M. Leventhal or Lionel P. Fortin or current or future
affiliates, associates or other persons acting in concert or as a group with
either of Messrs. Leventhal or Fortin. Consequently, the prohibition on voting
control shares will not apply to such persons.

                     COMMON STOCK AVAILABLE FOR FUTURE SALE
 
   
    As of June 1, 1998, BCP has outstanding 20,973,932 shares of Common Stock
and has reserved for issuance upon exercise of Stock Options or redemption of
Units 2,796,726 additional shares of Common Stock.
    
 
    Shares of Common Stock issued to holders of Units upon exercise of the
Redemption Rights, will be "restricted" securities under the meaning of Rule 144
promulgated under the Securities Act ("Rule 144") and may not be sold in the
absence of registration under the Securities Act unless an exemption from
registration is available, including exemptions contained in Rule 144. See
"Description of Securities-- Transfer Restrictions" and "Operating Partnership
Agreement--Redemption of OP Units."
 
    In general, under Rule 144 as currently in effect, if one year has elapsed
since the later of the date of acquisition of restricted shares from the Company
or any "affiliate" of the Company, as defined in Rule 144 (an "Affiliate"), the
acquiror or subsequent holder thereof is entitled to sell within any three-month
period a number of shares that does not exceed the greater of 1% of the then
outstanding Common Stock or the average weekly trading volume of the Common
Stock during the four calendar weeks preceding the date on which notice of the
sale is filed with the Commission. Sales under Rule 144 also are subject to
certain manner of sale provisions, notice requirements and the availability of
current public information about the Company which will require BCP to file
periodic reports under the Exchange Act. If two years have elapsed since the
date of acquisition of restricted shares from the Company or from any Affiliate
of the Company, and the acquiror or subsequent holder thereof is deemed not to
have been an Affiliate of the Company at any time during the three months
preceding a sale, such person would be entitled to sell such shares in the
public market under Rule 144(k) without regard to the volume limitations, manner
of sale provisions, public information requirements or notice requirements.
 
    No assurance can be given as to (i) the likelihood that an active market for
the shares will develop, (ii) the liquidity of any such market, (iii) the
ability of the stockholders to sell their Common Stock, or (iv) the prices that
stockholders may obtain for their Common Stock.
 
   
    In addition to the shares to be registered hereby, the holders of 2,528,296
Units have the right to demand, on any four occasions after September 1, 1999,
to have the common stock that they might receive upon the redemption of such
Units registered. The Company will bear all expenses incident to the
registration under the registration rights agreement, except that such expenses
shall not include any underwriting discounts or commissions, or transfer taxes,
if any, relating to such shares.

                        OPERATING PARTNERSHIP AGREEMENT
 
    THE FOLLOWING SUMMARY OF THE OPERATING PARTNERSHIP AGREEMENT DESCRIBES THE
MATERIAL PROVISIONS OF SUCH AGREEMENT. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE OPERATING PARTNERSHIP AGREEMENT.
 
CLASSES OF UNITS
 
    The Operating Partnership has authority to issue three classes of units of
limited partnership interests: Units; Convertible Units; and Incentive Units.
The Units, and the Incentive Units once issued (collectively, the "OP Units"),
will share equally on a unit-by-unit basis in all distributions of the Operating
Partnership. The Convertible Units will not participate in any distributions of
the Operating Partnership and represent solely the right to convert into a
certain number of Incentive Units (if any) with a fair market value equal to the
Incentive Return. See "The Company--Long-Term Incentive Plan."
 
MANAGEMENT
 
   
    The Operating Partnership is a Delaware limited partnership. BCP is the sole
general partner of, and holds approximately 88% of the economic interests in the
Operating Partnership. BCP holds an approximate 1% general partner interest in
the Operating Partnership and the balance is held as a limited partner interest.
BCP intends to conduct substantially all of its business through the Operating
Partnership and its subsidiaries.
    
 
    Pursuant to the Operating Partnership Agreement, BCP, as the sole general
partner of the Operating Partnership, generally has full, exclusive and complete
responsibility and discretion in the management, operation and control of the
Operating Partnership, including the ability to cause the Operating Partnership
to enter into certain major transactions, including acquisitions, developments
and dispositions of properties and refinancings of existing indebtedness. No
limited partner may take part in the operation, management or control of the
business of the Operating Partnership by virtue of being a holder of any class
of units of the Operating Partnership. Certain restrictions apply to the
Company's ability to engage in a Business Combination, as described more fully
under "Extraordinary Transactions" below.
 
    The limited partner of the Operating Partnership has agreed that in the
event of any conflict in the fiduciary duties owed by BCP to its stockholders
and by BCP, as general partner of the Operating Partnership, to such limited
partners, BCP may act in the best interests of BCP's stockholders without
violating its fiduciary duties to such limited partners or being liable for any
resulting breach of its duties to the limited partners.
 
    The Operating Partnership Agreement provides that all business activities of
BCP, including all activities pertaining to the acquisition and operation of
properties, must be conducted through the Operating Partnership, and that the
Operating Partnership must be operated in a manner that will enable BCP to
satisfy the requirements for being classified as a REIT.
 
REMOVAL OF THE GENERAL PARTNER; TRANSFER OF THE GENERAL PARTNER'S INTEREST
 
    The Operating Partnership Agreement provides that the limited partners may
not remove BCP as general partner of the Operating Partnership. BCP may not
transfer any of its interests as general or limited partner in the Operating
Partnership except (i) in connection with a merger or sale of all or
substantially all of its assets pursuant to a transaction for which it has
obtained the requisite approval in accordance with the terms of the Operating
Partnership Agreement, (ii) if the limited partners holding at least 66 2/3% of
the OP Units (excluding OP Units owned by BCP) consent to such transfer or (iii)
to certain affiliates of BCP.
 
                                       69
<PAGE>
AMENDMENTS OF THE OPERATING PARTNERSHIP AGREEMENT
 
    Generally, the Operating Partnership Agreement may be amended with the
approval of BCP, as general partner, and limited partners (including BCP)
holding a majority of the OP Units. Certain amendments that would, among other
things, convert a limited partner's interest into a general partner's interest,
modify the limited liability of a limited partner, alter the interest of a
partner in profits or losses or the right to receive any distributions, alter or
modify the redemption right described below, or cause the termination of the
Operating Partnership at a time or on terms inconsistent with those set forth in
the Operating Partnership Agreement must be approved by BCP and each limited
partner that would be adversely affected by such amendment. Notwithstanding the
foregoing, BCP, as general partner, has the power, without the consent of the
limited partners, to amend the Operating Partnership Agreement as may be
required to (1) add to the obligations of BCP as general partner or surrender
any right or power granted to BCP as general partner, (2) reflect the admission,
substitution, termination or withdrawal of partners in accordance with the terms
of the Operating Partnership Agreement, (3) establish the rights, powers, duties
and preferences of any additional partnership interests issued in accordance
with the terms of the Operating Partnership Agreement, (4) reflect a change of
an inconsequential nature that does not materially adversely affect the limited
partners, or cure any ambiguity, correct or supplement any provisions of the
Operating Partnership Agreement not inconsistent with law or with other
provisions of the Operating Partnership Agreement, or make other changes
concerning matters under the Operating Partnership Agreement that are not
otherwise inconsistent with the Operating Partnership Agreement or law, or (5)
satisfy any requirements of federal or state law. Certain provisions affecting
the rights and duties of BCP as general partner (e.g., restrictions on BCP's
power to conduct businesses other than owning OP Units; restrictions relating to
the issuance of securities of BCP and related capital contributions to the
Operating Partnership; restrictions relating to certain extraordinary
transactions involving BCP or the Operating Partnership) may not be amended
without the approval of a majority of the OP Units not held by BCP.
 
TRANSFER OF UNITS; SUBSTITUTE LIMITED PARTNERS
 
   
    The Operating Partnership Agreement provides that limited partners generally
may transfer their OP Units and Convertible Units without the consent of any
other person, but may substitute a transferee as a limited partner only with the
prior written consent of BCP as the sole general partner of the Operating
Partnership. In addition, limited partners may not transfer OP Units until the
one-year anniversary of the Closing of the Original Offering or in violation of
certain regulatory and other restrictions set forth in the Operating Partnership
Agreement. Notwithstanding the foregoing, the 2,528,296 Units issued to Luddite
Associates, a partnership owned by The Prudential Insurance Company of America
and its affiliates, in connection with the acquisition of Technology Square and
The Draper Building can generally be transferred to any direct or indirect
wholly-owned subsidiary of Prudential at any time after September 21, 1998, and
such transferee shall then be admitted as a substitute limited partner.
    
 
REDEMPTION OF OP UNITS
 
   
    The Operating Partnership will be obligated after the one-year anniversary
of the Closing Date of the Original Offering to redeem each OP Unit at the
request of the holder thereof for cash equal to the fair market value of such
unit at the time of such redemption (as determined in accordance with the
provisions of the Operating Partnership Agreement), provided that BCP may elect
to acquire any such OP Unit presented for redemption for one share of Common
Stock or an amount of cash of the same value. If Incentive Units are presented
for redemption, the election by BCP to acquire such Incentive Units for shares
of Common Stock must be approved by the Independent Directors. With each
redemption or acquisition by BCP, BCP's percentage ownership interest in the
Operating Partnership will increase. Beacon Capital Participation Plan shall
have certain rights, pursuant to separate registration rights agreements, to
have the issuance of shares of Common Stock that may be issued to it in exchange
for its
    
 
                                       70
<PAGE>
OP Units, or the resale of such shares, registered under the Securities Act. See
"Common Stock Available for Future Sale."
 
OPERATIONS
 
    The Operating Partnership Agreement requires that the Operating Partnership
be operated in a manner that will enable BCP to satisfy the requirements for
being classified as a REIT for federal tax purposes, to avoid any federal income
or excise tax liability imposed by the Code, and to ensure that the Operating
Partnership will not be classified as a "publicly traded partnership" for
purposes of Section 7704 of the Code. In addition, the Operating Partnership
will be operated in a manner so as to qualify it as a "real estate operating
company" under the Plan Assets Regulation, at least until such time as the
Common Stock qualifies as shares of "publicly offered securities" within the
meaning of the Plan Assets Regulation.
 
   
    In addition to the administrative and operating costs and expenses incurred
by the Operating Partnership, it is anticipated that the Operating Partnership
will pay all administrative costs and expenses of the Company (collectively, the
"Company Expenses") and such Company Expenses will be treated as expenses of the
Operating Partnership. The Company Expenses generally will include (i) all
expenses relating to the formation and continuity of existence of the Company,
(ii) all expenses relating to the offering and registration of securities by the
Company, (iii) all expenses associated with the preparation and filing of any
periodic reports by the Company under federal, state or local laws or
regulations, (iv) all expenses associated with compliance by the Company with
laws, rules and regulations promulgated by any regulatory body, and (v) all
other operating or administrative costs of the Company incurred in the ordinary
course of its business on behalf of the Operating Partnership.
    
 
ISSUANCE OF ADDITIONAL LIMITED PARTNERSHIP INTERESTS
 
    BCP as general partner is authorized, without the consent of the limited
partners, to cause the Operating Partnership to issue additional Units,
Incentive Units and Convertible Units to BCP, to the limited partners or to
other persons for such consideration and on such terms and conditions as BCP as
general partner deems appropriate. If additional OP Units are issued to BCP,
then BCP must (i) issue additional shares of Common Stock and must contribute to
the Operating Partnership the entire proceeds received by BCP from such issuance
or (ii) issue additional OP Units to all partners in proportion to their
respective interests in the Operating Partnership. In addition, BCP may cause
the Operating Partnership to issue to BCP additional partnership interests in
different series or classes, which may be senior to the OP Units, in conjunction
with an offering of securities of BCP having substantially similar rights, in
which the proceeds thereof are contributed to the Operating Partnership.
Consideration for additional partnership interests may be cash or other property
or assets. No limited partner has preemptive, preferential or similar rights
with respect to additional capital contributions to the Operating Partnership or
the issuance or sale of any partnership interests therein.
 
EXTRAORDINARY TRANSACTIONS
 
    The Operating Partnership Agreement provides that BCP may not generally
engage in any merger, consolidation or other combination with or into another
person or sale of all or substantially all of its assets, or any
reclassification, or any recapitalization or change of outstanding shares of
Common Stock (a "Business Combination"), unless the holders of OP Units will
receive, or have the opportunity to receive, the same consideration per OP Unit
as holders of Common Stock receive per share of Common Stock in the transaction;
if holders of OP Units will not be treated in such manner in connection with a
proposed Business Combination, BCP may not engage in such transaction unless
limited partners (other than BCP) holding at least 66 2/3% of the OP Units held
by limited partners vote to approve the Business Combination.
 
                                       71
<PAGE>
EXCULPATION AND INDEMNIFICATION OF THE GENERAL PARTNER
 
    The Operating Partnership Agreement generally provides that BCP, as general
partner of the Operating Partnership, will incur no liability to the Operating
Partnership or any limited partner for losses sustained or liabilities incurred
as a result of errors in judgment or of any act or omission if BCP carried out
its duties in good faith. In addition, BCP is not responsible for any misconduct
or negligence on the part of its agents, provided BCP appointed such agents in
good faith. BCP may consult with legal counsel, accountants, appraisers,
management consultants, investment bankers and other consultants and advisors,
and any action it takes or omits to take in reliance upon the opinion of such
persons, as to matters that BCP reasonably believes to be within their
professional or expert competence, shall be conclusively presumed to have been
done or omitted in good faith and in accordance with such opinion.
 
    The Operating Partnership Agreement also provides for indemnification of
BCP, the Directors and officers of BCP, and such other persons as BCP may from
time to time designate against any judgments, penalties, fines, settlements and
reasonable expenses actually incurred by such person in connection with the
preceding unless it is established that: (1) the act or omission of the
indemnified person was material to the matter giving rise to the preceding and
either was committed in bad faith or was the result of active and deliberate
dishonesty; (2) the indemnified person actually received an improper personal
benefit in money, property or services; or (3) in the case of any criminal
proceeding, the indemnified person had reasonable cause to believe that the act
or omission was unlawful.
 
TAX MATTERS
 
    BCP is the tax matters partner of the Operating Partnership and, as such,
has the authority to make tax elections under the Code on behalf of the
Operating Partnership.

                       FEDERAL INCOME TAX CONSIDERATIONS
 
    The following summary of material federal income tax considerations is based
upon current law and is for general information purposes only. The discussion
contained herein does not address all aspects of taxation that may be relevant
to particular stockholders in light of their personal investment or tax
circumstances, or to certain types of stockholders (including, without
limitation, insurance companies, tax-exempt organizations (except as described
below), financial institutions or broker-dealers, and, except as discussed
below, foreign corporations and persons who are not citizens or residents of the
United States) subject to special treatment under the federal income tax laws.
 
    The statements in this discussion are based on current provisions of the
Code, existing, temporary, and currently proposed Treasury Regulations
promulgated under the Code, the legislative history of the Code, existing
administrative rulings and practices of the Service, and judicial decisions. No
assurance can be given that future legislative, judicial, or administrative
actions or decisions, which may be retroactive in effect, will not affect the
accuracy of any statements in this Prospectus with respect to the transactions
entered into or contemplated prior to the effective date of such changes.
 
   
    EACH PROSPECTIVE PURCHASER SHOULD CONSULT HIS, HER OR ITS OWN TAX ADVISOR
REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM, HER OR IT OF THE PURCHASE,
OWNERSHIP, AND SALE OF THE COMMON STOCK, INCLUDING THE FEDERAL, STATE, LOCAL AND
FOREIGN TAX CONSEQUENCES OF SUCH PURCHASE, OWNERSHIP, AND SALE, AND OF POTENTIAL
CHANGES IN APPLICABLE TAX LAWS.
    
 
TAXATION OF THE COMPANY
 
   
    BCP will elect to be taxed as a REIT under Sections 856 through 860 of the
Code, commencing with the year ending on December 31, 1998.
    
 
    The sections of the Code relating to qualification and operation as a REIT
are highly technical and complex. The following discussion sets forth only the
material aspects of the Code sections that govern the federal income tax
treatment of a REIT and its stockholders. The discussion is qualified in its
entirety by the applicable Code provisions, Treasury Regulations promulgated
thereunder, and administrative and judicial interpretations thereof, all of
which are subject to change prospectively or retroactively.
 
    Goodwin, Procter & Hoar LLP has acted as counsel to BCP in connection with
the Offering and BCP's election to be taxed as a REIT. In the opinion of
Goodwin, Procter & Hoar LLP (the "Opinion"), provided that the elections and
other procedural steps described in this discussion of "Federal Income Tax
Considerations" are completed by BCP in a timely fashion, BCP will be organized
in conformity with the requirements for qualification as a REIT pursuant to
Sections 856 through 860 of the Code, and BCP's proposed method of operation
will enable it to continue to meet the requirements for qualification and
taxation as a REIT under the Code. Investors should be aware, however, that
opinions of counsel are not binding upon the Service or any court. It must be
emphasized that the Opinion is based on various assumptions and is conditioned
upon certain representations made by BCP as to factual matters, including
representations regarding the nature of BCP's properties and the past and future
conduct of its business. Such factual assumptions and representations are
described below in this discussion of "Federal Income Tax Considerations" and
are set out in the Opinion. Moreover, such qualification and taxation as a REIT
depends upon BCP's ability to meet on a continuing basis, through actual annual
operating results, distribution levels, and stock ownership, the various
qualification tests imposed under the Code discussed below. Goodwin, Procter &
Hoar LLP will not review BCP's compliance with those tests on a continuing
basis. Accordingly, no assurance can be given that the actual results of BCP's
operations for any particular taxable year will satisfy any such requirements.
For a discussion of the tax consequences of failure to qualify as a REIT. See
"--Failure to Qualify."
 
                                       73
<PAGE>
    If BCP qualifies for taxation as a REIT, it generally will not be subject to
federal corporate income tax on its net income that is distributed currently to
its stockholders. That treatment substantially eliminates the "double taxation"
(i.e., taxation at both the corporate and stockholder levels) that generally
results from an investment in a corporation. However, BCP will be subject to
federal income tax in the following circumstances. First, BCP will be taxed at
regular corporate rates on any undistributed REIT taxable income, including
undistributed net capital gains. Second, under certain circumstances, BCP may be
subject to the "alternative minimum tax" on its undistributed items of tax
preference, if any. Third, if BCP has (i) net income from the sale or other
disposition of "foreclosure property" that is held primarily for sale to
customers in the ordinary course of business or (ii) other nonqualifying income
from foreclosure property, it will be subject to tax at the highest corporate
rate on such income. Fourth, if BCP has net income from prohibited transactions
(which are, in general, certain sales or other dispositions of property (other
than foreclosure property) held primarily for sale to customers in the ordinary
course of business), such income will be subject to a 100% tax. Fifth, if BCP
should fail to satisfy the 75% gross income test or the 95% gross income test
(as discussed below), but has maintained its qualification as a REIT because
certain other requirements have been met, it will be subject to a 100% tax on
the gross income attributable to the greater of the amount by which BCP fails
the 75% or 95% gross income test, multiplied by a fraction intended to reflect
BCP's profitability. Sixth, if BCP should fail to distribute during each
calendar year at least the sum of (i) 85% of its REIT ordinary income for such
year, (ii) 95% of its REIT capital gain net income for such year (other than
such capital gain net income which BCP elects to retain and pay tax on) , and
(iii) any undistributed taxable income from prior periods, BCP would be subject
to a 4% excise tax on the excess of such required distribution over the amounts
actually distributed. Seventh, if BCP acquires any asset from a "C" corporation
(i.e., a corporation generally subject to full corporate-level tax) in a merger
or other transaction in which the basis of the asset in BCP's hands is
determined by reference to the basis of the asset (or any other asset) in the
hands of a "C" corporation and BCP recognizes gain on the disposition of such
asset during the 10-year period beginning on the date on which it acquired such
asset, then to the extent of such asset's "built-in-gain" (i.e., the excess of
the fair market value of such asset at the time of acquisition by BCP over the
adjusted basis in such asset at such time), BCP will be subject to tax at the
highest regular corporate rate applicable (as provided in Treasury Regulations
that have not yet been promulgated). The results described above with respect to
the tax on "built-in-gain" assume that BCP will elect pursuant to IRS Notice
88-19 to be subject to the rules described in the preceding sentence if it were
to make any such acquisition.
 
REQUIREMENTS FOR QUALIFICATION
 
    The Code defines a REIT as a corporation, trust, or association (i) that is
managed by one or more trustees or directors; (ii) the beneficial ownership of
which is evidenced by transferable shares, or by transferable certificates of
beneficial interest; (iii) that would be taxable as a domestic corporation, but
for Sections 856 through 860 of the Code; (iv) that is neither a financial
institution nor an insurance company subject to certain provisions of the Code;
(v) the beneficial ownership of which is held by 100 or more persons; (vi) not
more than 50% in value of the outstanding shares of which is owned, directly or
indirectly, by five or fewer individuals (as defined in the Code to include
certain entities) during the last half of each taxable year (the "5/50 Rule");
(vii) that makes an election to be a REIT (or has made such election for a
previous taxable year) and satisfies all relevant filing and other
administrative requirements established by the Service that must be met in order
to elect and maintain REIT status; (viii) that uses a calendar year for federal
income tax purposes; and (ix) that meets certain other tests, described below,
regarding the nature of its income and assets. The Code provides that conditions
(i) to (iv) above, inclusive, must be met during the entire taxable year and
that condition (v) above must be met during at least 335 days of a taxable year
of 12 months, or during a proportionate part of a taxable year of less than 12
months. Conditions (v) and (vi) above will not apply until after the first
taxable year for which an election is made by BCP to be taxed as a REIT. For
purposes of determining stock ownership under the 5/50 Rule, a supplemental
unemployment compensation benefits plan, a private foundation, or a portion of a
trust permanently set aside or
 
                                       74
<PAGE>
used exclusively for charitable purposes generally is considered an individual.
A trust that is a qualified trust under Code Section 401(a), however, generally
is not considered an individual and beneficiaries of such trust are treated as
holding shares of a REIT in proportion to their actuarial interests in such
trust for purposes of the 5/50 Rule. If BCP complies with all the requirements
for ascertaining the ownership of its outstanding stock in a taxable year and
does not know or have reason to know that it violated the 5/50 Rule, BCP will be
deemed to have complied with the 5/50 Rule for such taxable year.
 
   
    BCP believes it has issued sufficient Common Stock with sufficient diversity
of ownership pursuant to the Original Offering to allow it to satisfy
requirements (v) and (vi) in the preceeding paragraph. In addition, BCP's
Charter provides for restrictions regarding the transfer of the Common Stock
that are intended to assist BCP in continuing to satisfy the share ownership
requirements described in clauses (v) and (vi) above. However there can be no
assurance that BCP will continue to meet the REIT Stock Ownership Requirements.
Such transfer restrictions are described in "Description of Securities--Transfer
Restrictions."
    
 
    Code Section 856(i) provides that a corporation that is a "qualified REIT
subsidiary" shall not be treated as a separate corporation, and all assets,
liabilities, and items of income, deduction, and credit of a "qualified REIT
subsidiary" shall be treated as assets, liabilities, and items of income,
deduction, and credit of the REIT. A "qualified REIT subsidiary" is a
corporation, all of the capital stock of which is held by the REIT. If BCP
acquires a corporation already in existence at the time of acquisition, such
corporation would be treated as liquidating on the date of acquisition and BCP
would be required to distribute any C corporation earnings and profits of the
corporation before the end of the taxable year. Thus, in applying the
requirements described herein, any "qualified REIT subsidiaries" of BCP will be
ignored, and all assets, liabilities, and items of income, deduction, and credit
of such subsidiaries will be treated as assets, liabilities, and items of
income, deduction, and credit of BCP.
 
    In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that the REIT will be deemed to own its proportionate share
of the assets of the partnership and will be deemed to be entitled to the gross
income of the partnership attributable to such share. In addition, the assets
and gross income of the partnership will retain the same character in the hands
of the REIT for purposes of Section 856 of the Code, including for purposes of
satisfying the gross income and asset tests described below. BCP's proportionate
share of the assets and gross income of the Operating Partnership will be
treated as assets and gross income of BCP for purposes of applying the
requirements described herein.
 
INCOME TESTS
 
    In order for BCP to qualify and to maintain its qualification as a REIT, two
requirements relating to BCP's gross income must be satisfied annually. First,
at least 75% of BCP's gross income (excluding gross income from prohibited
transactions) for each taxable year must consist of defined types of income
derived directly or indirectly from investments relating to real property or
mortgages on real property (including "rents from real property" and interest on
obligations secured by mortgages on real property or on interests in real
property, and dividends or other distributions on and gain from the sale of
stock in other REITs) or from certain types of temporary investment income.
Second, at least 95% of BCP's gross income (excluding gross income from
prohibited transactions) for each taxable year must be derived from such real
property, mortgages on real property, or temporary investments, and from
dividends, other types of interest, and gain from the sale or disposition of
stock or securities, or from any combination of the foregoing.
 
    The rent received by BCP from the tenants of the Real Property ("Rent") will
qualify as "rents from real property" in satisfying the gross income tests for a
REIT described above only if several conditions are met. First, the amount of
Rent must not be based, in whole or in part, on the income or profits of any
person. However, an amount received or accrued generally will not be excluded
from the term "rents from real property" solely by reason of being based on a
fixed percentage or percentages of receipts or sales or
 
                                       75
<PAGE>
solely by reason of being based on the income or profits of a tenant if such
tenant derives substantially all of its gross income from the related property
through the sub-leasing of substantially all of its interest in the property to
the extent the amounts received by such tenant would be characterized as rents
from real property if received by the REIT. Second, the Code provides that the
Rent received from a tenant will not qualify as "rents from real property" in
satisfying the gross income tests if BCP, or a direct or indirect owner of 10%
or more of BCP, owns 10% or more of such tenant, either actually or
constructively (a "Related Party Tenant"). Third, if Rent attributable to
personal property, leased in connection with a lease of Real Property, is
greater than 15% of the total Rent received under the lease, then the portion of
Rent attributable (taking into account both actual and constructive ownership)
to such personal property will not qualify as "rents from real property."
Finally, for the Rent to qualify as "rents from real property," BCP generally
must not operate or manage the Real Property or furnish or render services to
the tenants of such Real Property, other than through an "independent
contractor" who is adequately compensated by the tenants and from whom BCP
derives no revenue. The "independent contractor" requirement, however, does not
apply to the extent that the services provided by BCP are "usually or
customarily rendered" in connection with the rental of space for occupancy only
and are not otherwise considered "rendered to the occupant."
 
    BCP has represented that it will not charge Rent for any portion of any Real
Property that is based, in whole or in part, on the income or profits of any
person (except by reason of being based on a fixed percentage or percentages of
receipts or sales, as described above) to the extent that the receipt of such
Rent would jeopardize BCP's status as a REIT. In addition, BCP has represented
that, to the extent that it receives Rent from a Related Party Tenant, such Rent
will not cause BCP to fail to satisfy either the 75% or 95% gross income test.
BCP also has represented that it will not allow the Rent attributable to
personal property leased in connection with any lease of Real Property to exceed
15% of the total Rent received under the lease, if the receipt of such Rent
would cause BCP to fail to satisfy either the 75% or 95% gross income test.
Finally, BCP has represented that it will not operate or manage its Real
Property or furnish or render noncustomary services to the tenants of its Real
Property other than through an "independent contractor," to the extent that such
operation or the provision of such services would jeopardize BCP's status as a
REIT.
 
    The Ownership Limit and the Excess Share Provisions in the Company's Charter
are designed in part to prevent a stockholder of the Company from owning Company
stock that would cause the Company to own, actually or constructively, 10% or
more of the ownership interests in a tenant, including any BCP Sister Corp.
However, because the relevant constructive ownership rules are broad and it is
not possible to monitor continually direct and indirect transfers of Company
shares, and because the Charter provisions referred to above may not be
effective, there can be no absolute assurance that transfers or other events
will not cause the Company to constructively own 10% or more of one or more
tenants at some future date.
 
    The term "interest," as defined for purposes of the 75% and 95% gross income
tests, generally does not include any amount received or accrued (directly or
indirectly) if the determination of such amount depends in whole or in part on
the income or profits of any person. However, an amount received or accrued
generally will not be excluded from the term "interest" solely by reason of
being based on a fixed percentage or percentages of receipts or sales. In
addition, an amount received or accrued generally will not be excluded from the
term "interest" solely by reason of being based on the income or profits of a
debtor if the debtor derives substantially all of its gross income from the
related property through the leasing of substantially all of its interests in
the property, to the extent the amounts received by the debtor would be
characterized as rents from real property if received by a REIT. Furthermore, to
the extent that interest from a loan that is based on the cash proceeds from the
sale of the property securing the loan constitutes a "shared appreciation
provision" (as defined in the Code), income attributable to such participation
feature will be treated as gain from the sale of the secured property, which
generally is qualifying income for purposes of the 75% and 95% gross income
tests.
 
                                       76
<PAGE>
    Interest will qualify as "interest on obligations secured by mortgages on
real property or on interests in real property" if the obligation is secured by
a mortgage on real property having a fair market value, as of the date on which
the commitment to make or purchase the obligation becomes binding on BCP, at
least equal to the highest principal amount of the loan outstanding during the
taxable year. However, if BCP receives interest income with respect to a
mortgage loan that is secured by both real property and other property and the
highest principal amount of the loan outstanding during a taxable year exceeds
the fair market value of the real property on the date on which the commitment
to acquire or originate the mortgage loan becomes binding on BCP, the interest
income will be apportioned between the real property and the other property,
which apportionment may cause BCP to recognize income that is not qualifying
income for purposes of the 75% gross income test.
 
    BCP may receive income not described above that is not qualifying income for
purposes of one or both of the 75% and 95% gross income tests. For example, it
is possible that certain fees for services rendered by the Operating Partnership
will not be qualifying income for purposes of either gross income test. It is
not anticipated that the Operating Partnership will receive a significant amount
of such fees. In addition, dividends received from Real Estate Companies that
are C corporations generally will be qualifying income for purposes of the 95%
gross income test, but not the 75% gross income test. BCP will monitor the
amount of nonqualifying income produced by its assets and has represented that
it will manage its portfolio in order to comply at all times with the two gross
income tests.
 
    REITs generally are subject to tax at the maximum corporate rate on any
income from foreclosure property (other than income that would be qualifying
income for purposes of the 75% gross income test), less expenses directly
connected with the production of such income. "Foreclosure property" is defined
as any real property (including interests in real property) and any personal
property incident to such real property (i) that is acquired by a REIT as the
result of such REIT having bid in such property at foreclosure, or having
otherwise reduced such property to ownership or possession by agreement or
process of law, after there was a default (or default was imminent) on a lease
of such property or on an indebtedness owed to the REIT that such property
secured, (ii) for which the related loan was acquired by the REIT at a time when
default was not imminent or anticipated, and (iii) for which such REIT makes a
proper election to treat such property as foreclosure property. BCP does not
anticipate that it will receive any income from foreclosure property that is not
qualifying income for purposes of the 75% gross income test, but, if BCP does
receive any such income, BCP will make an election to treat the related property
as foreclosure property.
 
    Property acquired by BCP will not be eligible for the election to be treated
as foreclosure property ("Ineligible Property") if the related loan was acquired
by BCP at a time when default was imminent or anticipated. In addition, income
received with respect to such Ineligible Property may not be qualifying income
for purposes of the 75% or 95% gross income tests.
 
    Net income derived from a prohibited transaction is subject to a 100% tax.
The term "prohibited transaction" generally includes a sale or other disposition
of property (other than foreclosure property) that is held primarily for sale to
customers in the ordinary course of a trade or business. BCP intends to conduct
its operations so that no asset owned by BCP or the Operating Partnership will
be held for sale to customers and that a sale of any such asset will not be in
the ordinary course of BCP's or the Operating Partnership's business. Whether
property is held "primarily for sale to customers in the ordinary course of a
trade or business" depends, however, on the facts and circumstances in effect
from time to time, including those related to a particular property.
Nevertheless, BCP will attempt to comply with the terms of safe-harbor
provisions in the Code prescribing when asset sales will not be characterized as
prohibited transactions. Complete assurance cannot be given, however, that BCP
can comply with the safe-harbor provisions of the Code or avoid owning property
that may be characterized as property held "primarily for sale to customers in
the ordinary course of a trade or business."
 
                                       77
<PAGE>
    From time to time, BCP may enter into hedging transactions with respect to
one or more of its assets or liabilities. Any such hedging transactions could
take a variety of forms, including, without limitation, interest rate swap
contracts, interest rate cap or floor contracts, futures or forward contracts,
and options. To the extent that BCP enters into such a contract to hedge against
the interest rate risks of any indebtedness incurred to acquire or carry real
estate assets, any periodic income or gain from the disposition of such contract
should be qualifying income for purposes of the 95% gross income test, but not
the 75% gross income test. To the extent that BCP hedges with other types of
financial instruments or in other situations, it may not be entirely clear how
the income from those transactions will be treated for purposes of the various
income tests that apply to REITs under the Code. BCP intends to structure any
hedging transactions in a manner that does not jeopardize its status as a REIT.
 
    If BCP fails to satisfy one or both of the 75% and 95% gross income tests
for any taxable year, it nevertheless may qualify as a REIT for such year if it
is entitled to relief under certain provisions of the Code. Those relief
provisions generally will be available if BCP's failure to meet such tests is
due to reasonable cause and not due to willful neglect, BCP attaches a schedule
of the sources of its income to its return, and any incorrect information on the
schedule was not due to fraud with intent to evade tax. It is not possible,
however, to state whether in all circumstances BCP would be entitled to the
benefit of those relief provisions. As discussed above in "--Taxation of the
Company," even if those relief provisions apply, a 100% tax would be imposed on
the gross income attributable to the greater of the amount by which BCP fails
the 75% or 95% gross income test, multiplied by a fraction intended to reflect
BCP's profitability.
 
ASSET TESTS
 
    BCP, at the close of each quarter of each taxable year, also must satisfy
three tests relating to the nature of its assets. First, at least 75% of the
value of BCP's total assets must be represented by cash or cash items (including
certain receivables), government securities, "real estate assets," or, in cases
where BCP raises new capital through stock or long-term (at least five-year)
debt offerings, temporary investments in stock or debt instruments during the
one-year period following BCP's receipt of such capital. The term "real estate
assets" includes interests in real property, interests in mortgages on real
property to the extent the principal balance of a mortgage does not exceed the
fair market value of the associated real property, and shares of other REITs.
For purposes of the 75% asset test, the term "interest in real property"
includes an interest in mortgage loans or land or improvements thereon, such as
buildings or other inherently permanent structures (including items that are
structural components of such buildings or structures), a leasehold of real
property, and an option to acquire real property (or a leasehold of real
property). Second, not more than 25% of the Company's total assets may be
represented by securities other than those in the 75% asset class. Third, of the
investments not included in the 75% asset class, the value of any one issuer's
securities owned by BCP may not exceed 5% of the value of BCP's total assets,
and BCP may not own more than 10% of any one issuer's outstanding voting
securities (except for its interests in the Operating Partnership, the General
Partner, the Limited Partner, any qualified REIT subsidiaries, and other
qualified REITs).
 
    BCP expects that any interests in Real Estate Companies and interests in
Real Property that it acquires generally will be qualifying assets for purposes
of the 75% asset test. If BCP acquires any interest in a Real Estate Company
that is a C corporation, such interest may not (i) represent more than 5% of the
value of BCP's total assets or (ii) constitute more than 10% of the Real Estate
Company's outstanding voting securities. BCP will monitor the status of the
assets that it acquires for purposes of the various asset tests and has
represented that it will manage its portfolio in order to comply at all times
with such tests.
 
    If BCP should fail to satisfy the asset tests at the end of a calendar
quarter, such a failure would not cause it to lose its REIT status if (i) it
satisfied the asset tests at the close of the preceding calendar quarter and
(ii) the discrepancy between the value of BCP's assets and the asset test
requirements arose from changes in the market values of its assets and was not
wholly or partly caused by the acquisition of one or more non-qualifying assets.
If the condition described in clause (ii) of the preceding sentence were not
 
                                       78
<PAGE>
satisfied, BCP still could avoid disqualification by eliminating any discrepancy
within 30 days after the close of the calendar quarter in which it arose.
 
DISTRIBUTION REQUIREMENTS
 
    In order to avoid corporate income taxation of the earnings that it
distributes, BCP is required to distribute with respect to each taxable year
dividends (other than capital gain dividends) to its stockholders in an
aggregate amount at least equal to (i) the sum of (A) 95% of its "REIT taxable
income" (computed without regard to the dividends paid deduction and its net
capital gain) and (B) 95% of the net income (after tax), if any, from
foreclosure property, minus (ii) the sum of certain items of noncash income.
Such distributions must be paid in the taxable year to which they relate, or in
the following taxable year if declared before BCP timely files its federal
income tax return for such year and if paid on or before the first regular
dividend payment date after such declaration. To the extent that BCP does not
distribute all of its net capital gain or distributes at least 95%, but less
than 100%, of its "REIT taxable income," as adjusted, it will be subject to tax
thereon at regular ordinary and capital gains corporate tax rates. Furthermore,
if BCP should fail to distribute during each calendar year (or, in the case of
distributions with declaration and record dates falling in the last three months
of the calendar year, by the end of the January immediately following such year)
at least the sum of (i) 85% of its REIT ordinary income for such year, (ii) 95%
of its REIT capital gain income for such year (other than capital gain income
which BCP elects to retain and pay tax on), and (iii) any undistributed taxable
income from prior periods, BCP would be subject to a 4% nondeductible excise tax
on the excess of such required distribution over the amounts actually
distributed. Pursuant to recently enacted legislation, BCP may elect to retain,
rather than distribute, all or a portion of its net long-term capital gains. The
effect of such an election is that (i) BCP is required to pay the tax on such
gains, (ii) U.S. stockholders (as defined below), while required to include
their proportionate share of the undistributed long-term capital gains in
income, will receive a credit or refund for their share of the tax paid by BCP
and (iii) the basis of a U.S. stockholder's Common Stock would be increased by
the amount of the undistributed long-term capital gains (minus the amount of
capital gains tax paid by BCP) included in such U.S. stockholder's long-term
capital gains.
 
    In certain circumstances, the Company's investments may generate income for
federal income tax purposes without a corresponding receipt of cash ("Phantom
Income"). In order for BCP to meet REIT qualifications and/or avoid tax at the
REIT level on such Phantom Income, BCP may be forced to use cash generated from
other sources, including, without limitation, asset sales and borrowings, to
make required distributions. See "Risk Factors--Legal and Tax Risks--Tax Risks."
 
    Under certain circumstances, BCP may be able to rectify a failure to meet
the distribution requirements for a year by paying "deficiency dividends" to its
stockholders in a later year, which may be included in BCP's deduction for
dividends paid for the earlier year. Although BCP may be able to avoid being
taxed on amounts distributed as deficiency dividends, it will be required to pay
to the Service interest based upon the amount of any deduction taken for
deficiency dividends.
 
RECORDKEEPING REQUIREMENTS
 
    Pursuant to applicable Treasury Regulations, BCP must maintain certain
records and request on an annual basis certain information from its stockholders
designed to disclose the actual ownership of its outstanding stock. Failure to
comply with such record keeping requirements could result in substantial
monetary penalties to BCP. BCP intends to comply with such requirements.
 
EXCESS INCLUSION INCOME
 
    It is anticipated that BCP may purchase mortgage loans. If BCP purchases
such assets and is deemed to have issued debt obligations having two or more
maturities, the payments on which correspond to payments on such mortgage loans,
such arrangement will be treated as a "taxable mortgage pool" for
 
                                       79
<PAGE>
federal income tax purposes. If all or a portion of BCP is considered a "taxable
mortgage pool," BCP's status as a REIT generally should not be impaired;
however, a portion of BCP's taxable income may be characterized as "excess
inclusion income" and allocated to the stockholders of BCP. Any excess inclusion
income (i) could not be offset by net operating losses of a stockholder, (ii)
would be subject to tax as "unrelated business taxable income" to a tax-exempt
stockholder, (iii) would be subject to the application of federal income tax
withholding (without reduction pursuant to any otherwise applicable income tax
treaty) with respect to amounts allocable to foreign stockholders, and (iv)
would be taxable (at the highest corporate tax rate) to BCP, rather than its
stockholders, to the extent allocable to shares of stock of BCP held by
disqualified organizations (generally, tax-exempt entities not subject to
unrelated business income tax, including governmental organizations).
 
   
IMPACT OF FUTURE LEGISLATION
    
 
   
    BCP's qualification as a REIT or its ability to utilize the BCP Sister Corp.
structure could be affected as a result of future legislation. In that regard,
Congress recently enacted, and the Clinton Administration signed into law,
certain revenue proposals as part of the Internal Revenue Service Restructuring
and Reform Act of 1998 that included, among other things, a freeze on the
grandfathered status of REITs that are "paired" or "stapled" with a related
operating company. Unlike such "paired" or "stapled" structures, the proposed
BCP Sister Corp. structure would be a "paper clip" structure in which interests
in the BCP Sister Corp. distributed to the Company's stockholders could be
transferred independently from the Company's Common Stock. Although such
legislation does not affect "paper clip" structures, there can be no assurance
that the recently enacted legislation will not place legislative or judicial
scrutiny on the "paper clip" structure, or that legislation adversely affecting
such structure will not be proposed and enacted. See "Risk Factors--Legal and
Tax Risks--Tax Risks."
    
 
FAILURE TO QUALIFY
 
    If BCP fails to qualify for taxation as a REIT in any taxable year, and the
relief provisions do not apply, BCP will be subject to tax (including any
applicable alternative minimum tax) on its taxable income at regular corporate
rates. Distributions to BCP's stockholders in any year in which BCP fails to
qualify will not be deductible by BCP nor will they be required to be made. In
such event, to the extent of BCP's current and accumulated earnings and profits,
all distributions to stockholders will be taxable as ordinary income and,
subject to certain limitations of the Code, corporate distributees may be
eligible for the dividends received deduction. Unless entitled to relief under
specific statutory provisions, BCP also will be disqualified from taxation as a
REIT for the four taxable years following the year during which BCP ceased to
qualify as a REIT. It is not possible to state whether in all circumstances BCP
would be entitled to statutory relief from its failure to qualify as a REIT.
 
TAXATION OF TAXABLE U.S. STOCKHOLDERS
 
    As used herein, the term "U.S. stockholder" means a holder of Common Stock
that for U.S. federal income tax purposes is (i) a citizen or resident of the
United States, (ii) a corporation, partnership, or other entity created or
organized in or under the laws of the United States or of any state or political
subdivision thereof, (iii) an estate whose income from sources without the
United States is includible in gross income for U.S. federal income tax purposes
regardless of its connection with the conduct of a trade or business within the
United States, or (iv) any trust with respect to which (A) a U.S. court is able
to exercise primary supervision over the administration of such trust and (B)
one or more U.S. persons have the authority to control all substantial decisions
of the trust.
 
    As long as BCP qualifies as a REIT, distributions (including distributions
of the BCP Sister Corp. equity interests by BCP upon the formation of the BCP
Sister Corp.) made to BCP's taxable U.S. stockholders out of current or
accumulated earnings and profits (and not designated as capital gain dividends
or retained capital gains) will be taken into account by such U.S. stockholders
as ordinary
 
                                       80
<PAGE>
   
income and will not be eligible for the dividends received deduction generally
available to corporations. Distributions that are designated as capital gain
dividends by BCP will be taxed as long-term capital gains (to the extent that
they do not exceed BCP's actual net capital gain for the taxable year) without
regard to the period for which the stockholder has held his Common Stock.
Pursuant to recently enacted legislation, in the case of a stockholder who is an
individual, an estate or a trust, long-term capital gains and losses are
separated into three tax rate groups, a 20% group, a 25% group and a 28% group,
and are subject to tax at the rate effective for each group. Pursuant to Notice
97-64, 1997-47 IRB 1, the Company will designate capital gain dividends, if any,
as 20% rate gain distributions, 25% rate gain distributions or 28% rate gain
distributions and detail such designations in a manner intended to comply with
applicable requirements. Final regulations, if and when issued by the Treasury
Department, could affect the rules set forth in the Notice. In addition, the
Service has not issued regulations or other guidance regarding the application
of the new rates to sales of interests in REITs such as the Company, and it
remains unclear how the new rules will affect such sales, if at all. The Service
has not yet issued guidance modifying the rules set forth in the Notice to take
into account the recent elimination of the 18-month holding period required for
individuals, estates and trusts to be eligible for the preferential 20% capital
gains rate. If BCP elects to retain capital gains rather than distribute them, a
U.S. stockholder will be deemed to receive a capital gain dividend equal to the
amount of such retained capital gains. A U.S. stockholder will be allowed a
credit against its federal income tax liability for its proportionate share of
tax paid by BCP on retained capital gains. See "--Requirements for
Qualification." Such gains are subject to apportionment among the three tax rate
groups as set forth above. Corporate stockholders may be required to treat up to
20% of certain capital gain dividends as ordinary income. Distributions in
excess of current and accumulated earnings and profits will not be taxable to a
stockholder to the extent that they do not exceed the adjusted basis of the
stockholder's Common Stock, but rather will reduce the adjusted basis of such
stock. To the extent that such distributions in excess of current and
accumulated earnings and profits exceed the adjusted basis of a stockholder's
Common Stock, such distributions will be included in income as long-term capital
gain (or, in the case of all taxpayers short-term capital gain if the Common
Stock had been held for one year or less), provided that the Common Stock is a
capital asset in the hands of the stockholder. In addition, any distribution
declared by BCP in October, November, or December of any year and payable to a
stockholder of record on a specified date in any such month shall be treated as
both paid by BCP and received by the stockholder on December 31 of such year,
provided that the distribution is actually paid by BCP during January of the
following calendar year.
    
 
    Stockholders may not include in their individual income tax returns any net
operating losses or capital losses of BCP. Instead, such losses would be carried
over by BCP for potential offset against its future income (subject to certain
limitations). Taxable distributions from BCP and gain from the disposition of
the Common Stock will not be treated as passive activity income and, therefore,
stockholders generally will not be able to apply any "passive activity losses"
(such as losses from certain types of limited partnerships in which a
stockholder is a limited partner) against such income. In addition, taxable
distributions from BCP generally will be treated as investment income for
purposes of the investment interest limitations. Capital gains from the
disposition of Common Stock (or distributions treated as such), however, will be
treated as investment income only if the stockholder so elects, in which case
such capital gains will be taxed at ordinary income rates. BCP will notify
stockholders after the close of BCP's taxable year as to the portions of the
distributions attributable to that year that constitute ordinary income or
capital gain dividends and in the case of capital gain dividends to
non-corporate stockholders, those designated as 20% rate gain distributions, 25%
rate gain distributions and 28% rate gain distributions.
 
    It is possible that BCP may invest in certain types of mortgage loans that
may cause it under certain circumstances to recognize taxable income in excess
of its economic income (also known as "Phantom Income") and to experience an
offsetting excess of economic income over its taxable income in later years. As
a result, stockholders may from time to time be required to pay federal income
tax on distributions that economically represent a return of capital, rather
than a dividend. Such distributions would be offset in later years by
distributions representing economic income that would be treated as returns of
capital for
 
                                       81
<PAGE>
federal income tax purposes. Accordingly, if BCP receives Phantom Income, its
stockholders may be required to pay federal income tax with respect to such
income on an accelerated basis, i.e., before such income is realized by the
stockholders in an economic sense. If there is taken into account the time value
of money, such an acceleration of federal income tax liabilities would cause
stockholders to receive an after-tax rate of return on an investment in BCP that
would be less than the after-tax rate of return on an investment with an
identical before-tax rate of return that did not generate Phantom Income. In
general, as the ratio of BCP's Phantom Income to its total income increases, the
after-tax rate of return received by a taxable stockholder of BCP will decrease.
BCP will consider the potential effects of Phantom Income on its taxable
stockholders in managing its investments.
 
TAXATION OF STOCKHOLDERS ON THE DISPOSITION OF THE COMMON STOCK
 
   
    In general, any gain or loss realized upon a taxable disposition of the
Common Stock by a U.S. stockholder who is not a dealer in securities will be
treated as capital gain or loss. Any such capital gain or loss generally will
(x) in the case of U.S. stockholders which are corporations, be long-term
capital gain or loss if the Common Stock has been held for more than 12 months,
and (y) in the case of U.S. stockholders who are non-corporate taxpayers, be
long-term capital gain or loss taxed at a maximum federal income tax rate of (i)
20% if the U.S. stockholder's holding period in such Common Stock was more than
18 months at the time of such disposition or (ii) 28% if the U.S. stockholder's
holding period was more than one year but not more than 18 months at the time of
such disposition. However, the Internal Revenue Service Restructuring and Reform
Act of 1998 eliminated the 18-month holding period requirements, effective for
taxable years ending after December 31, 1997, and therefore the 20% long-term
capital gains rate will generally apply to capital assets held more than one
year. In general, any loss upon a sale or exchange of Common Stock by a U.S.
stockholder who has held such Common Stock for six months or less (after
applying certain holding period rules) will be treated as long-term capital loss
to the extent of distributions from BCP required to be treated by that
stockholder as long-term capital gain.
    
 
INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING
 
    BCP will report to its U.S. stockholders and to the Service the amount of
distributions paid during each calendar year, and the amount of tax withheld, if
any. Under the backup withholding rules, a stockholder may be subject to backup
withholding at the rate of 31% with respect to distributions paid unless such
holder (i) is a corporation or comes within certain other exempt categories and,
when required, demonstrates this fact or (ii) provides a taxpayer identification
number, certifies as to no loss of exemption from backup withholding, and
otherwise complies with the applicable requirements of the backup withholding
rules. A stockholder who does not provide BCP with his correct taxpayer
identification number also may be subject to penalties imposed by the Service.
Any amount paid as backup withholding will be creditable against the
stockholder's income tax liability.
 
TAXATION OF TAX-EXEMPT STOCKHOLDERS
 
    Tax exempt entities, including qualified employee pension and profit sharing
trusts and individual retirement accounts ("Exempt Organizations"), generally
are exempt from federal income taxation. However, they are subject to taxation
on their unrelated business taxable income ("UBTI"), as defined in Section
512(a)(1) of the Code. While many investments in real estate generate UBTI, the
Service has issued a published ruling that dividend distributions from a REIT to
an exempt employee pension trust do not constitute UBTI, provided that the
shares of the REIT are not otherwise used in an unrelated trade or business of
the exempt employee pension trust. Based on that ruling, amounts distributed by
BCP to Exempt Organizations generally should not constitute UBTI. However, if an
Exempt Organization finances its acquisition of the Common Stock with debt, a
portion of its income from BCP will constitute UBTI pursuant to the
"debt-financed property" rules. In addition, in certain circumstances, a pension
trust that owns more than 10% of BCP's stock is required to treat a percentage
of the dividends from BCP as
 
                                       82
<PAGE>
UBTI. This rule applies to a pension trust holding more than 10% (by value) of
BCP's stock only if (i) the percentage of income of BCP that is UBTI (determined
as if BCP were a pension trust) is at least 5% and (ii) BCP is treated as a
"pension-held" REIT. BCP will be treated as a "pension-held" REIT if (i) BCP
qualifies as a REIT by reason of the modification of the 5/50 Rule that allows
the beneficiaries of the pension trust to be treated as holding shares of BCP in
proportion to their actuarial interests in the pension trust, and (ii) either
(A) one pension trust owns more than 25% of the value of BCP's stock or (B) a
group of pension trusts individually holding more than 10% of the value of BCP's
stock collectively owns more than 50% of the value of BCP's stock. BCP is
unlikely to become a "pension-held" REIT because, pursuant to the Aggregate
Stock Ownership Limit and the Look-Through Ownership Limit in the Charter of
BCP, no person may beneficially own shares of Common Stock in excess of 9.8% of
the outstanding shares of Common Stock of BCP; provided, however, that certain
Look-Through Entities may beneficially own up to 15% of such shares of Common
Stock. Although the Board of Directors of BCP has the discretion to waive the
application of the Aggregate Stock Ownership Limit or the Look-Through Ownership
Limit with respect to any person, the Board of Directors intends to grant such
waivers only in a manner that would not cause BCP to be or become a
"pension-held" REIT. However, there can be no assurance that BCP will not become
a "pension-held" REIT or that pension trusts will not be required to treat a
percentage of dividends received from BCP as UBTI.
 
TAXATION OF NON-U.S. STOCKHOLDERS
 
    The rules governing U.S. federal income taxation of nonresident alien
individuals, foreign corporations, foreign partnerships, and other foreign
stockholders (collectively, "Non-U.S. Stockholders") are complex, and no attempt
will be made herein to provide more than a summary of such rules. PROSPECTIVE
NON-U.S. STOCKHOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS TO DETERMINE
THE IMPACT OF FEDERAL, STATE, AND LOCAL INCOME TAX LAWS WITH REGARD TO AN
INVESTMENT IN THE COMMON STOCK, INCLUDING ANY REPORTING REQUIREMENTS.
 
   
    Distributions to Non-U.S. Stockholders that are not attributable to gain
from sales or exchanges by BCP of U.S. real property interests and are not
designated by BCP as capital gains dividends or retained capital gains will be
treated as dividends of ordinary income to the extent that they are made out of
current or accumulated earnings and profits of BCP. Such distributions
ordinarily will be subject to a withholding tax equal to 30% of the gross amount
of the distribution unless an applicable tax treaty reduces or eliminates that
tax. However, if income from the investment in the Common Stock is treated as
effectively connected with the Non-U.S. Stockholder's conduct of a U.S. trade or
business, the Non-U.S. Stockholder generally will be subject to federal income
tax at graduated rates, in the same manner as U.S. stockholders are taxed with
respect to such distributions (and also may be subject to the 30% branch profits
tax in the case of a Non-U.S. Stockholder that is a non-U.S. corporation). BCP
expects to withhold U.S. income tax at the rate of 30% on the gross amount of
any such distributions made to a Non-U.S. Stockholder unless (i) a lower treaty
rate applies and any required form evidencing eligibility for that reduced rate
is filed with BCP or (ii) the Non-U.S. Stockholder files an IRS Form 4224 with
BCP claiming that the distribution is effectively connected income. Furthermore,
on October 6, 1997, the U.S. Treasury Department issued final Treasury
regulations governing information reporting and the certification procedures
regarding withholding and backup withholding on certain amounts paid to Non-U.S.
Stockholders after December 31, 1998 (the "New Withholding Regulations"). The
New Withholding Regulations may alter the procedure for claiming the benefits of
an income tax treaty.
    
 
    Distributions in excess of current and accumulated earnings and profits of
BCP will not be taxable to a Non-U.S. Stockholder to the extent that such
distributions do not exceed the adjusted basis of the stockholder's Common
Stock, but rather will reduce the adjusted basis of such shares. To the extent
that distributions in excess of current and accumulated earnings and profits
exceed the adjusted basis of a Non-U.S. Stockholder's Common Stock, such
distributions will give rise to tax liability if the Non-U.S.
 
                                       83
<PAGE>
Stockholder would otherwise be subject to tax on any gain from the sale or
disposition of his Common Stock, as described below. Because it generally cannot
be determined at the time a distribution is made whether or not such
distribution will be in excess of current and accumulated earnings and profits,
the entire amount of any distribution normally will be subject to withholding at
the same rate as a dividend. However, amounts so withheld are refundable to the
extent it is determined subsequently that such distribution was, in fact, in
excess of current and accumulated earnings and profits of BCP. BCP is required
to withhold 10% of any distribution in excess of BCP's current and accumulated
earnings and profits. Consequently, although BCP intends to withhold at a rate
of 30% on the entire amount of any distribution, to the extent that BCP does not
do so, any portion of a distribution not subject to withholding at a rate of 30%
will be subject to withholding at a rate of 10%.
 
    For any year in which BCP qualifies as a REIT, distributions that are
attributable to gain from sales or exchanges by BCP of U.S. real property
interests (i.e., interests in real property located in the United States and
interests in U.S. corporations at least 50% or whose assets consist of U.S. real
property interests) will be taxed to a Non-U.S. Stockholder under the provisions
of the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA"). Under
FIRPTA, distributions attributable to gain from sales of U.S. real property
interests are taxed to a Non-U.S. Stockholder as if such gain were effectively
connected with a U.S. trade or business. Non-U.S. Stockholders thus would be
taxed at the normal capital gain rates applicable to U.S. stockholders (subject
to applicable alternative minimum tax and a special alternative minimum tax in
the case of nonresident alien individuals). Distributions subject to FIRPTA also
may be subject to the 30% branch profits tax in the hands of a non-U.S.
corporate stockholder not entitled to treaty relief or exemption. BCP is
required to withhold 35% of any distribution that is designated by BCP as a
capital gains dividend. The amount withheld is creditable against the Non-U.S.
Stockholder's FIRPTA tax liability.
 
    Gain recognized by a Non-U.S. Stockholder upon a sale of his or her Common
Stock generally will not be taxed under FIRPTA if BCP is a "domestically
controlled REIT," defined generally as a REIT in which at all times during a
specified testing period less than 50% in value of the stock was held directly
or indirectly by non-U.S. persons. Although it is currently anticipated that BCP
will be a "domestically controlled REIT" and, therefore, that the sale of the
Common Stock will not be subject to taxation under FIRPTA, there can be no
assurance that BCP will be a "domestically-controlled REIT." Even if such gain
is not subject to FIRPTA, such gain will be taxable to a Non-U.S. Stockholder if
(i) investment in the Common Stock is effectively connected with the Non-U.S.
Stockholder's U.S. trade or business, in which case the Non-U.S. Stockholder
will be subject to the same treatment as U.S. stockholders with respect to such
gain, or (ii) the Non-U.S. Stockholder is a nonresident alien individual who was
present in the United States for 183 days or more during the taxable year and
certain other conditions apply, in which case the nonresident alien individual
will be subject to a 30% tax on the individual's capital gains. If the gain on
the sale of the Common Stock were to be subject to taxation under FIRPTA, the
Non-U.S. Stockholder would be subject to the same treatment as U.S. stockholders
with respect to such gain (subject to applicable alternative minimum tax and a
special alternative minimum tax in the case of nonresident alien individuals).
In addition, a purchaser of Common Stock subject to taxation under FIRPTA would
generally be required to deduct and withhold a tax equal to 10% of the amount
realized on the disposition by a Non-U.S. Stockholder. Any amount withheld would
be creditable against the Non-U.S. Stockholder's FIRPTA tax liability.
 
    Additional issues may arise pertaining to information reporting and backup
withholding with respect to Non-U.S. Stockholders. The New Withholding
Regulations alter the application of the information reporting and backup
withholding rules to Non-U.S. Stockholders. Non-U.S. Stockholders should consult
with a tax advisor with respect to any such information reporting and backup
withholding requirements. Backup withholding with respect to a Non-U.S.
Stockholder is not an additional tax. Rather, the amount of any backup
withholding with respect to a payment to a Non-U.S. Stockholder will be allowed
as a credit against any United States federal income tax liability of such
Non-U.S. Stockholder. If withholding results
 
                                       84
<PAGE>
in an overpayment of taxes, a refund may be obtained, provided that the required
information is furnished to the Service.
 
OTHER TAX CONSEQUENCES
 
    BCP, BCP's stockholders, the Operating Partnership or its General Partner or
Limited Partners may be subject to state and local tax in various states and
localities, including those states and localities in which it or they transact
business, own property, or reside. The state and local tax treatment of the
Company and its stockholders in such jurisdictions may differ from the federal
income tax treatment described above. Consequently, prospective stockholders
should consult their own tax advisors regarding the effect of state and local
tax laws upon an investment in the Common Stock. In addition, the Taxpayer
Relief Act of 1997 includes several provisions, some of which have been
described in the discussion above, that will liberalize certain of the
requirements for qualification as a REIT. However, these provisions will have
neither a material beneficial effect nor a material adverse effect on BCP's
ability to operate as a REIT.
 
BCP SISTER CORP.
 
    Each BCP Sister Corp. organized as a corporation will pay federal, state and
local income taxes on its taxable income at regular corporate rates. Any such
taxes will reduce amounts available for distribution by the BCP Sister Corp. to
its stockholders.

                              ERISA CONSIDERATIONS
 
    ERISA and the Code impose certain restrictions on (a) Plans, including
individual retirement accounts or Keogh plans, (b) any entities whose underlying
assets include Plan assets by reason of a Plan's investment in such entities
("Plan Assets Entities") and (c) persons who have certain specified
relationships to such Plans and Plan Assets Entities ("Parties-in-Interest"
under ERISA and "Disqualified Persons" under the Code). Moreover, based on the
reasoning of the United States Supreme Court in JOHN HANCOCK LIFE INS. CO. V.
HARRIS TRUST AND SAV. BANK, 114 S. Ct. 517 (1993), an insurance company's
general account may be deemed to include assets of the Plans investing in the
general account (e.g., through the purchase of an annuity contract), and the
insurance company might be treated as a Party-in-Interest or Disqualified Person
with respect to a Plan by virtue of such investment. ERISA also imposes certain
duties on persons who are fiduciaries of Plans subject to ERISA and prohibits
certain transactions between a Plan and Parties-in-Interest or Disqualified
Persons with respect to such Plans.
 
THE TREATMENT OF THE COMPANY'S UNDERLYING ASSETS UNDER ERISA
 
    The DOL has issued the Plan Assets Regulation which defines what constitutes
the assets of a Plan. This regulation provides that, as a general rule, the
underlying assets and properties of corporations, partnerships, trusts and
certain other entities in which a Plan purchases an "equity interest" will be
deemed for purposes of ERISA and the Code to be assets of the investing Plan
unless certain exceptions apply. The Plan Assets Regulation defines an "equity
interest" as any interest in an entity other than an instrument that is treated
as indebtedness under applicable local law and which has no substantial equity
features. The Common Stock offered hereby should be treated as "equity
interests" for purposes of the Plan Assets Regulation.
 
    One exception under the Plan Assets Regulation provides that an investing
Plan's assets will not include any of the underlying assets of an entity if at
all times less than 25% of each class of "equity" interests in the entity is
held by "benefit plan investors," which is defined to include Plans that are not
subject to ERISA such as foreign benefit plans, governmental pension plans and
individual retirement accounts as well as Plans that are subject to ERISA.
Another exception is provided for an investment in an "operating company," which
is defined in the Plan Assets Regulation to include a "real estate operating
company." To be a "real estate operating company" an entity must have, on the
date of its first long-term investment and on certain annual testing dates
thereafter, at least 50% of its assets (other than short-term investments
pending long-term commitment or distribution to investors), valued at cost,
invested in real estate that is managed or developed and with respect to which
such entity has the right to substantially participate in such management or
development activities. Another exception under the Plan Assets Regulation
provides that an investing Plan's assets will not include any of the underlying
assets of an entity if the class of "equity" interests in question is a class of
"publicly offered securities." Publicly offered securities are securities that
are (i) widely held (i.e., held by 100 or more investors who are independent of
the issuer and each other), (ii) freely transferable, and (iii) part of a class
of securities registered under Section 12(b) or 12(g) of the Exchange Act.
 
    The Board of Directors of the Company and any Sister Corp. will take such
steps as may be necessary to qualify for one or more of the exceptions available
under the Plan Assets Regulation and thereby prevent the assets of the Company
or any BCP Sister Corp. from being treated as assets of any investing Plan.
Specifically, BCP intends to qualify as a real estate operating company until at
least such time as the Common Stock qualifies as a class of publicly offered
securities. In this connection, BCP has obtained an opinion of counsel that, on
the date of the Operating Partnership's first long-term investment BCP qualified
as a real estate operating company. It is intended that, thereafter, on at least
one date during each of BCP's "annual valuation periods" (as defined in the Plan
Assets Regulation) until at least such time as the Common Stock qualifies as
publicly offered securities, at least 50% of the assets of BCP (valued at cost
and excluding certain short-term investments) will be invested, by reason of its
investment in the Operating Partnership, in real estate which is managed or
developed and as to which BCP will have
 
                                       86
<PAGE>
the right to substantially participate in the management or development of the
real estate. Consequently, BCP should qualify as a real estate operating
company. In addition, with respect to any BCP Sister Corp., the Company will
take such steps as may be necessary to qualify such BCP Sister Corp. as an
operating company or a venture capital operating company or for another
available exception under the Plan Assets Regulation prior to distribution of
its equity interests.
 
    Any Plan fiduciary that proposes to cause a Plan to purchase Common Stock
should consult with its counsel with respect to the potential applicability of
ERISA and the Code to such investment and determine on its own whether any
exceptions or exemptions are applicable and whether all conditions of any such
exceptions or exemptions have been satisfied. Moreover, each Plan fiduciary
should determine whether, under the general fiduciary standards of investment
prudence and diversification, an investment in the Common Stock is appropriate
for the Plan, taking into account the overall investment policy of the Plan and
the composition of the Plan's investment portfolio.
 
                              SELLING STOCKHOLDERS
 
    The Common Stock was originally issued by BCP and sold by NationsBanc
Montgomery Securities LLC (the "Initial Purchaser"), in a transaction exempt
from registration requirements of the Securities Act, to persons reasonably
believed by the Initial Purchaser to be "qualified institutional buyers" (as
defined in Rule 144A under the Securities Act), to a limited number of
institutional "accredited investors" (as defined in Rule 501 (a) (1), (2), (3)
or (7) under the Securities Act) and to individual "accredited investors" (as
defined in Rule 501 (a) (4), (5) or (6) under the Securities Act). The Selling
Stockholders may from time to time offer and sell pursuant to this Prospectus
any or all of the Common Stock. The term Selling Stockholders, includes the
holders listed below and the beneficial owners of the Common Stock and their
transferees, pledgees, donees or other successors.
 
   
    The following table sets forth information with respect to the Selling
Stockholders of the Common Stock and the respective number of shares of Common
Stock beneficially owned by each Selling Stockholders that may be offered
pursuant to this Prospectus. The Company is obligated by the terms of a
Registration Rights Agreement to file this Registration Statement on behalf of
each of the listed stockholders. Inclusion on this list does not imply that any
person or entity will actually offer or sell any of the shares registered on
his, her or its behalf.

(1) Such Selling Stockholder is affiliated with an investment bank or law firm
    which has provided professional services to the Registrant.
    
 
   
    Except as shown above, none of the Selling Stockholders has, or within the
past three years has had, any position, office or other material relationship
with the BCP or any of its predecessors or affiliates.
    
 
                                       97
<PAGE>
   
Because the Selling Stockholders may, pursuant to this Prospectus, offer all or
some portion of the Common Stock, no estimate can be given as to the amount of
the Common Stock that will be held by the Selling Stockholders upon termination
of any such sales. In addition, the Selling Stockholders identified above may
have sold, transferred or otherwise disposed of all or a portion of their Common
Stock since the date on which they provided the information regarding their
Common Stock, in transactions exempt from the registration requirements of the
Securities Act, including transactions pursuant to Rule 144 under the Securities
Act.
    
 
                                       98
<PAGE>
   
                              PLAN OF DISTRIBUTION
    
 
    The Offered Securities may be sold from time to time to purchasers directly
by the Selling Stockholders. Alternatively, the Selling Stockholders may from
time to time offer the Offered Securities to or through underwriters,
broker/dealers or agents, who may receive compensation in the form of
underwriting discounts, concessions or commissions from the Selling Stockholders
or the purchasers of such securities for whom they may act as agents. The
Selling Stockholders and any underwriters, broker/dealers or agents that
participate in the distribution of Offered Securities may be deemed to be
"underwriters" within the meaning of the Securities Act and any profit on the
sale of such securities and any discounts, commissions, concessions or other
compensation received by any such underwriter, broker/dealer or agent may be
deemed to be underwriting discounts and commissions under the Securities Act.
 
    The Offered Securities may be sold from time to time in one or more
transactions at fixed prices, at prevailing market prices at the time of sale,
at varying prices determined at the time of sale or at negotiated prices. The
sale of the Offered Securities may be effected in transactions (which may
involve crosses or block transactions) (i) on any national securities exchange
or quotation service on which the Offered Securities may be listed or quoted at
the time of sale, (ii) in the over-the-counter market, (iii) in transactions
otherwise than on such exchanges or in the over-the-counter market or (iv)
through the writing of options. At the time a particular offering of the Offered
Securities is made, a Prospectus Supplement, if required, will be distributed
which will set forth the aggregate amount and type of Offered Securities being
offered and the terms of the offering, including the name or names of any
underwriters, broker/dealers or agents, any discounts, commissions and other
terms constituting compensation from the Selling Stockholders and any discounts,
commissions or concessions allowed or reallowed or paid to broker/ dealers.
 
    Each Common Stock certificate contains a legend to the effect that the
holder thereof, by its acceptance thereof, will be deemed to have agreed to be
bound by the provisions of the Registration Rights Agreement. In that regard,
each holder is deemed to have agreed that, upon receipt of notice from the
Company of the occurrence of any event which makes a statement in this
prospectus untrue in any material respect or which requires the making of any
changes in such prospectus in order to make the statements therein not
misleading, or of certain other events specified in the Registration Rights
Agreement, such holder will suspend the sale of Common Stock pursuant to this
prospectus until the Company has amended or supplemented such prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented prospectus to such holder or the Company has given notice that the
sale of the Common Stock may be resumed.
 
    To comply with the securities laws of certain jurisdictions, if applicable,
the Offered Securities will be offered or sold in such jurisdictions only
through registered or licensed brokers or dealers. In addition, in certain
jurisdictions the Offered Securities may not be offered or sold unless they have
been registered or qualified for sale in such jurisdictions or any exemption
from registration or qualification is available and is complied with.
 
    The Selling Stockholders will be subject to applicable provisions of the
Exchange Act and the rules and regulations thereunder, which provisions may
limit the timing of the purchases and sales of any of the Offered Securities by
the Selling Stockholders. The foregoing may affect the marketability of such
securities.
 
    All expenses of the registration of the Offered Securities will be paid by
the Company, including, without limitation, Commission filing fees and expenses
of compliance with state securities or "blue sky" laws; provided, however, that
the Selling Stockholders will pay all the underwriting discounts and selling
commissions, if any. The Selling Stockholders will be indemnified by the Company
against certain civil liabilities, including certain liabilities under the
Securities Act, or will be entitled to contribution in connection therewith. The
Company will be indemnified by the Selling Stockholders severally against
 
                                       99
<PAGE>
certain civil liabilities, including certain liabilities under the Securities
Act, or will be entitled to contribution in connection therewith.
 
                                 LEGAL MATTERS
 
    Certain legal matters will be passed upon for the Company by Goodwin,
Procter & Hoar LLP, Boston, Massachusetts. Certain partners of Goodwin, Procter
& Hoar LLP directly or indirectly own an aggregate of 7,237 shares of Common
Stock of the Company.

                      FOR THE YEAR ENDED DECEMBER 31, 1997
              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
   
    (A) Reflects the historical condensed consolidated statement of operations
of the Company for the period January 21, 1998 (inception) through June 30,
1998. The Company was not in existence prior to January 21, 1998. See the
historical consolidated financial statements and notes thereto of the Company
included elsewhere in this prospectus.
    
 
   
    (B) Reflects the acquisitions of The Athenaeum Portfolio, Technology Square
and The Draper Building and The Breunig Portfolio based on the historical
operations of such properties for periods prior to acquisition by the Company.
The Athenaeum Portfolio acquisition reflects the formation by the Company of a
50% joint venture with PW Acquisitions IX, LLC, an affiliate of PaineWebber,
subsequent to the closing of the acquisition of The Athenaeum Portfolio as if
the formation of the joint venture had occurred on January 1, 1997. The joint
venture will be accounted for using the equity method of accounting and,
accordingly, 50% of the historical operations of The Athenaeum Portfolio,
adjusted for depreciation using an asset life of 40 years, and an allocation
between land and buildings of $35,771 and $159,656, respectively, has been
reflected in equity in earnings of joint venture. The other acquired properties
are owned directly by the Company. The Technology Square and The Draper Building
acquisition also reflects estimated depreciation based upon an asset life of 40
years, and an allocation between land and buildings of $36,162 and $87,304,
respectively. The Breunig Portfolio acquisition also reflects estimated
depreciation based upon an asset life of 40 years, and an allocation between
land and buildings of $13,425 and $77,775, respectively. See the Combined
Historical Summary of Gross Income and Direct Operating Expenses and notes
thereto for each of the properties included elsewhere in this prospectus.
    
 
   
    (C) Reflects interest income reduction attributed to cash used to fund the
acquisitions of The Athenaeum Portfolio, Technology Square and The Draper
Building, The Breunig Portfolio and the Sunnyvale Development, and the interest
earned from the loan receivable from the joint venture which holds The Athenaeum
Portfolio properties.
    
 
   
    (D) Minority interest in operating partnership represents a 12.4% minority
interest in the Operating Partnership.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of
  Beacon Capital Partners, Inc.
 
    We have audited the accompanying consolidated balance sheet of Beacon
Capital Partners, Inc. as of March 31, 1998 and the related consolidated
statements of operations, stockholders' equity and cash flows for the period
from January 21, 1998 (inception) through March 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Beacon Capital
Partners, Inc. at March 31, 1998, and the consolidated results of its operations
and its cash flows for the period from January 21, 1998 (inception) through
March 31, 1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                                 MARCH 31, 1998
              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
1. ORGANIZATION
 
    Beacon Capital Partners, Inc. ("BCP") was incorporated on January 21, 1998
as a Massachusetts corporation (the "Formation"), and was initially capitalized
through loans payable from the two founders (Messrs. Leventhal and Fortin) of
BCP, which were repaid in May 1998. BCP intends to qualify as a real estate
investment trust under the Internal Revenue Code of 1986, as amended. BCP was
formed to develop, acquire, lease and manage real estate and real estate related
assets.
 
    On March 17, 1998, BCP was reincorporated as a Maryland corporation and on
March 20, 1998 it completed an initial private offering (the "Original
Offering") in accordance with Rule 144A of the Securities Act. BCP initially
issued 17,360,769 common shares with proceeds, net of expenses, of $323,110.
Subsequent to March 31, 1998, 3,613,163 additional shares were issued through
the exercise of the underwriter's over-allotment, with proceeds, net of
expenses, of $67,185.
 
    In connection with the reincorporation of BCP in Maryland, BCP established
Beacon Capital Partners, L.P. (the "Operating Partnership"). BCP and the
Operating Partnership are collectively referred to as the "Company". The
Operating Partnership is a Delaware limited partnership. BCP is the sole general
partner of, and holds approximately 99% of the economic interest in, the
Operating Partnership. BCP holds an approximate 1% general partnership interest
in the Operating Partnership and the balance is held as a limited partnership
interest. The limited partnership interests not held by BCP are presented as
minority interest in the accompanying consolidated financial statements. The
term of the Operating Partnership commenced on March 16, 1998 and shall continue
until January 1, 2056 or until such time as a Liquidating Event, as defined, has
occurred. As contemplated in the Original Offering, a contribution of $4,200 was
due from an entity controlled by Messrs. Leventhal and Fortin to the Operating
Partnership for a 1% limited partner interest. For technical reasons, such
contribution could only be made subsequent to the closing of the first real
estate transaction of the Company. The $4,200 contribution was made on May 4,
1998.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF ACCOUNTING
 
    The accompanying consolidated financial statements are prepared in
accordance with generally accepted accounting principles and include the
accounts of BCP and its majority-owned subsidiary, Beacon Capital Partners, L.P.
BCP consolidates all wholly-owned subsidiaries and those majority-owned
subsidiaries in which it exercises control. Investor entities over which BCP can
exercise influence, but does not control, are accounted for on the equity
method. All significant intercompany transactions and balances have been
eliminated in consolidation.
 
USE OF ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements. Actual results could differ from those estimates.

                         BEACON CAPITAL PARTNERS, INC.
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                                 MARCH 31, 1998
              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES
 
    For the period ending March 31, 1998, BCP had limited operations. Although
BCP is not yet able to elect to be taxed as a real estate investment trust
("REIT") under the Internal Revenue Code, BCP intends to make such election on
its initial Federal return for the taxable year ended December 31, 1998. As a
result of such election, BCP will generally not be subject to Federal income
taxes to the extent that it makes timely distributions to its shareholders at
least equal to its taxable income and meets certain other requirements for
qualification as a real estate investment trust.
 
    BCP has indicated that it may acquire and operate businesses that do not
satisfy the REIT qualification tests prescribed by the Internal Revenue Code.
Transactions that give rise to such assets and income are expected to be owned
through a C corporation known as a "paper clip", the shares of such entity would
be distributed to BCP's stockholders. Such C corporation, if formed, will be
subject to Federal, state and local taxation.
 
REVENUE RECOGNITION
 
    Revenues are recognized when earned and the amounts can be reasonably
estimated on the accrual basis of accounting.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of short-term, highly liquid assets with
original maturities of three months or less from the date of purchase.
 
FURNITURE, FIXTURES AND EQUIPMENT
 
    Furniture, fixtures and equipment are recorded at cost and depreciated over
their useful lives, ranging from three to ten years.
 
STOCK OPTIONS AND OTHER AWARDS
 
   
    BCP has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related Interpretations
in accounting for its employee stock options because the alternative fair value
accounting provided for under FASB Statement No. 123, "Accounting for Stock-
Based Compensation," requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB 25, because the
exercise price of BCP's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.
    
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    BCP is required to disclose the fair value of financial instruments, for
which it is practicable to estimate such fair value. The fair value of financial
instruments are estimates based upon market conditions and perceived risks at
March 31, 1998 and require varying degrees of management judgment.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                                 MARCH 31, 1998
              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
The fair value of financial instruments presented may not be indicative of
amounts BCP could realize on the disposition of the financial instruments.
 
    Cash and cash equivalents are carried at an amount, which due to their
nature, approximates fair value.
 
BASIC EARNINGS PER COMMON SHARE
 
    Computation of basic earnings per common share is based upon the weighted
average number of shares of common stock outstanding during the period
subsequent to the Original Offering.
 
    As BCP has no dilutive securities, there is no difference between basic and
diluted earnings per share of common stock.
 
3. STOCK INCENTIVE PLAN
 
    The Company has adopted a Stock Incentive Plan, which authorizes the grant
of options to purchase shares of common stock and other stock-based awards to
the Company's executive officers, independent directors and employees and other
key persons. The Stock Incentive Plan will be administered by the Compensation
Committee of the Board of Directors (the "Administrator").
 
    The maximum number of shares of common stock reserved and available for
issuance under the Stock Incentive Plan will be such aggregate number of shares
as does not exceed the sum of (i) 12% of the outstanding equity interests in the
Company (including common stock and units subject to redemption rights) as
determined as of the final original offering closing date plus (ii) as of the
last business day of each calendar quarter ending after the final original
offering closing date, an additional positive number equal to 10% of any net
increase of outstanding equity interests in the Company.
 
    The Stock Incentive Plan permits the granting of (i) options to purchase
common stock intended to qualify as incentive stock options ("Incentive
Options") under Section 422 of the Internal Revenue Code and (ii) options that
do not so qualify ("Non-Qualified Options"). The option exercise price of each
option may not be less than 100% of the fair market value of the common stock on
the date of grant in the case of Incentive Options, and may not be less than 25%

exercised. Options may be made exercisable in installments, and the
exercisability of options may be accelerated by the Administrator.

4. LONG-TERM INCENTIVE PLAN
 
    The Company has adopted a Long-Term Incentive Plan which is designed to
reward certain members of management for growth of the Company's Funds from
Operations, as defined by the National Association of Real Estate Investment
Trusts, in excess of a specified benchmark. If the Company's Funds from
Operations exceeds the specified benchmark, management will be entitled to
receive an incentive return which shall be calculated at the end of the three
year period following the completion of the first calendar year following the
closing of the original offering (the "Determination Date").
 
    The incentive return shall equal the product of (A) 12% of the dollar amount
by which (i) the Actual Return, as defined, exceeds (ii) the Base Return, as
defined, multiplied by (B) the weighted average of shares of common stock and
units outstanding for the 12 months immediately preceding the Determination Date
multiplied by (C) the Company's Multiple, as defined.
 
    The Long-Term Incentive Plan will take the form of a convertible unit which
will be issued to an affiliated organization in connection with the closing of
the original offering. The convertible unit is convertible at the Determination
Date into a certain number of incentive units in the Operating Partnership with
a fair market value equal to the amount of the incentive return. No amount has
been earned with respect to the Long-Term Incentive Plan.
 
5. SUBSEQUENT EVENTS
 
    On May 1, 1998 the Company purchased a portfolio of eleven buildings in
Cambridge, MA known as The Athenaeum Portfolio. The mixed-use portfolio consists
of approximately 970,000 square feet and contains office, laboratory and retail
uses as well as a 1,530 space parking garage. The purchase price for the
portfolio was $195,000, including the assumption of approximately $69,000 of
first mortgage debt. Subsequent to the closing of the transaction, the Company
completed the formation of a joint venture with an affiliate of PaineWebber, in
which both parties hold a 50% equity interest in the properties.
 
    On April 22, 1998, the Company entered into a purchase and sale agreement
with The Prudential Insurance Company of America ("Prudential") to acquire a
four-building complex known as Technology

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
 
                                 JUNE 30, 1998
 
              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
1. ORGANIZATION
 
    Beacon Capital Partners, Inc. ("BCP") was incorporated on January 21, 1998
as a Massachusetts corporation (the "Formation"), and was initially capitalized
through loans payable from the two founders (Messrs. Leventhal and Fortin) of
BCP, which were repaid in May 1998. BCP intends to qualify as a real estate
investment trust under the Internal Revenue Code of 1986, as amended. BCP was
formed to develop, acquire, lease and manage real estate and real estate related
assets.
 
   
    On March 17, 1998, BCP was reincorporated as a Maryland corporation and on
March 20, 1998 it completed an initial private offering (the "Original
Offering") in accordance with Rule 144A of the Securities Act. BCP initially
issued 17,360,769 common shares with proceeds, net of expenses, of $323,110. In
April, 1998, 3,613,163 additional shares were issued through the exercise of the
underwriter's over-allotment, with proceeds, net of expenses, of $66,620.
    
 
   
    In connection with the reincorporation of BCP in Maryland, BCP established
Beacon Capital Partners, L.P. (the "Operating Partnership"). BCP and the
Operating Partnership are collectively referred to as the "Company". The
Operating Partnership is a Delaware limited partnership. BCP is the sole general
partner of, and holds, as of June 30, 1998, approximately 88% of the economic
interest in, the Operating Partnership. BCP holds an approximate 1% general
partnership interest in the Operating Partnership and the balance is held as a
limited partnership interest. The limited partnership interests not held by BCP
are presented as minority interest in the accompanying consolidated financial
statements. The term of the Operating Partnership commenced on March 16, 1998
and shall continue until January 1, 2056 or until such time as a Liquidating
Event, as defined, has occurred.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF ACCOUNTING
 
   
    The accompanying consolidated financial statements are prepared in
accordance with generally accepted accounting principles and include the
accounts of BCP and its majority-owned subsidiary, Beacon Capital Partners, L.P.
BCP consolidates all wholly-owned subsidiaries and those majority-owned
subsidiaries in which it exercises control. Investor entities over which BCP can
exercise influence, but does not control, are accounted for on the equity
method. All significant intercompany transactions and balances have been
eliminated in consolidation.
    
 
   
    The financial statements of BCP have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form S-11 and Rule 10-01 of Regulation S-X. In the
opinion of management, all adjustments (consisting of normal recurring accruals)
considered necessary of a fair presentation have been included. Operating
results for interim periods are not necessarily indicative of the results that
may be expected for the full year.
    
 
USE OF ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements. Actual results could differ from those estimates.

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
 
                                 JUNE 30, 1998
 
              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES
 
    For the period ending June 30, 1998, BCP had limited operations. Although
BCP is not yet able to elect to be taxed as a real estate investment trust
("REIT") under the Internal Revenue Code, BCP intends to make such election on
its initial Federal return for the taxable year ended December 31, 1998. As a
result of such election, BCP will generally not be subject to Federal income
taxes to the extent that it makes timely distributions to its shareholders at
least equal to its taxable income and meets certain other requirements for
qualification as a real estate investment trust.
 
    BCP has indicated that it may acquire and operate businesses that do not
satisfy the REIT qualification tests prescribed by the Internal Revenue Code.
Transactions that give rise to such assets and income are expected to be owned
through a C corporation known as a "paper clip", the shares of such entity would
be distributed to BCP's stockholders. Such C corporation, if formed, will be
subject to Federal, state and local taxation.
 
REVENUE RECOGNITION
 
   
    Revenues are recognized when earned and the amounts can be reasonably
estimated on the accrual basis of accounting. Rental income from operating
leases is recognized on a straight-line basis over the life of the lease
agreements.
    
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of short-term, highly liquid assets with
original maturities of three months or less from the date of purchase.
 
REAL ESTATE
 
   
    Buildings are recorded at cost and are depreciated on the straight-line
method over their estimated useful life of forty years. The cost of buildings
includes the purchase price of the property, legal fees and other acquistion
costs. Acquisition costs associated with the purchase of new property consist of
third party costs and internal direct costs only, and have been capitalized to
the appropriate assets.
    
 
    BCP measures impairment in accordance with FASB Statement No. 121,
ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE
DISPOSED OF, which requires impairment losses to be recorded on specific
long-lived assets used in operations where indicators of impairment are present
and the undiscounted cash flows (net realizable value) estimated to be generated
by those assets are less than the assets' carrying amount.
 
    Furniture, fixtures and equipment are depreciated using the straight-line
method over their expected useful lives of three to ten years.
 
INVESTMENTS IN AND ADVANCE TO JOINT VENTURE
 
    BCP uses the equity method of accounting for their earnings in their
property joint venture. Losses in excess of investments are not recorded where
BCP has not guaranteed nor does it intend to provide any future financial
support to the respective property.

              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
STOCK OPTIONS AND OTHER AWARDS
 
    BCP has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related Interpretations
in accounting for its employee stock options because the alternative fair value
accounting provided for under FASB Statement No. 123, "Accounting for Stock-
Based Compensation," requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB 25, because the
exercise price of BCP's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.
 
    Compensation attributable to the Company's Long-Term Incentive Plan will be
charged to expense over the period covered by the Plan.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
   
    BCP is required to disclose the fair value of financial instruments, for
which it is practicable to estimate such fair value. The fair value of financial
instruments are estimates based upon market conditions and perceived risks at
June 30, 1998 and require varying degrees of management judgment. The fair value
of financial instruments presented may not be indicative of amounts BCP could
realize on the disposition of the financial instruments.
    
 
    Cash and cash equivalents are carried at an amount, which due to their
nature, approximates fair value.
 
BASIC EARNINGS PER COMMON SHARE
 
    Computation of basic earnings per common share is based upon the weighted
average number of shares of common stock outstanding during the period
subsequent to the Original Offering.
 
    As BCP has no dilutive securities, there is no difference between basic and
diluted earnings per share of common stock.
 
   
3. INVESTMENT IN AND ADVANCE TO JOINT VENTURE
    
 
   
    The investment in and advance to joint venture represents the Company's
interest in Beacon/PW Kendall LLC, which is jointly owned by the Company and PW
Acquisitions IX, LLC, an affiliate of PaineWebber. As of June 30, 1998, both
members had obtained a $5,000 equity interest in Beacon/PW Kendall LLC.
Additionally the Company provided a loan to the joint venture of approximately
$117,000. In August, the Company and PW Aquisitions IX, LLC will each make
equity contributions of approximately

directors and employees and other key persons. The Stock Incentive Plan will be
administered by the Compensation Committee of the Board of Directors (the
"Administrator").
 
    The maximum number of shares of common stock reserved and available for
issuance under the Stock Incentive Plan will be such aggregate number of shares
as does not exceed the sum of (i) 12% of the outstanding equity interests in the
Company (including common stock and units subject to redemption rights) as
determined as of the final original offering closing date plus (ii) as of the
last business day of each calendar quarter ending after the final original
offering closing date, an additional positive number equal to 10% of any net
increase of outstanding equity interests in the Company.
 
    The Stock Incentive Plan permits the granting of (i) options to purchase
common stock intended to qualify as incentive stock options ("Incentive
Options") under Section 422 of the Internal Revenue Code and (ii) options that
do not so qualify ("Non-Qualified Options"). The option exercise price of each
option may not be less than 100% of the fair market value of the common stock on
the date of grant in the case of Incentive Options, and may not be less than 25%
of the fair market value of the common stock on the date of grant in the case of
Non-Qualified Options.
 
    The term of each option will be fixed and may not exceed ten years from date
of grant in the case of an Incentive Option. The Administrator will determine at
what time or times each option may be exercised and, subject to the provisions
of the Stock Incentive Plan, the period of time, if any, after retirement,
death, disability or termination of employment during which options may be
exercised. Options may be made exercisable in installments, and the
exercisability of options may be accelerated by the Administrator.
 
    Changes in options outstanding under the Stock Incentive Plan during the
period were as follows:

5. LONG-TERM INCENTIVE PLAN
 
    The Company has adopted a Long-Term Incentive Plan which is designed to
reward certain members of management for growth of the Company's Funds from
Operations, as defined by the National Association of Real Estate Investment
Trusts, in excess of a specified benchmark. If the Company's Funds from
Operations exceeds the specified benchmark, management will be entitled to
receive an incentive return which shall be calculated at the end of the three
year period following the completion of the first calendar year following the
closing of the original offering (the "Determination Date").

              (DOLLARS IN THOUSANDS, EXCEPT FOR PER SHARE AMOUNTS)
 
5. LONG-TERM INCENTIVE PLAN (CONTINUED)
    The incentive return shall equal the product of (A) 12% of the dollar amount
by which (i) the Actual Return, as defined, exceeds (ii) the Base Return, as
defined, multiplied by (B) the weighted average of shares of common stock and
units outstanding for the 12 months immediately preceding the Determination Date
multiplied by (C) the Company's Multiple, as defined.
 
    The Long-Term Incentive Plan will take the form of a convertible unit which
will be issued to an affiliated organization in connection with the closing of
the original offering. The convertible unit is convertible at the Determination
Date into a certain number of incentive units in the Operating Partnership with
a fair market value equal to the amount of the incentive return. No amount has
been earned with respect to the Long-Term Incentive Plan.
 
6. SUBSEQUENT EVENTS
 
   
    On July 1, 1998 the Company purchased a portfolio of fourteen properties in
Dallas, TX known as The Breunig Portfolio. The mixed-use portfolio consists of
approximately 1,335,000 square feet and contains seven office properties and
seven research & development (R&D) properties. The purchase price for the
portfolio was $91,200.
    
 
   
    On August 9, 1998, the Company entered into a joint venture agreement with
Mathilda Partners LLC, an affiliate of Menlo Equities, a California based
developer, by which the Company has agreed to fund 87.5% of the equity required
to develop two Class A office buildings and Mathilda Partners LLC has agreed to
fund 12.5% of such equity. The venture is under contract to acquire a
twelve-acre site on Mathilda Avenue in Sunnyvale, CA, on which the venture plans
to construct two four-story office buildings with surface parking. Although it
is anticipated that the buildings will contain approximately 267,000 square
feet, certain changes in the entitlements for the property will be required to
increase the permitted density from the currently permitted 187,000 square feet.
In addition to funding approximately 40% of the development expenditures
(including the acquisition of the land) from cash contributions, the venture
intends to finance the balance of those expenditures with a construction loan
from an institutional lender. The scope of the development budget has not been
finalized, but it is anticipated to be approximately $57,000 if the full 267,000
square feet are constructed.

Beacon Capital Partners, Inc.
 
    We have audited the accompanying Combined Historical Summary of Gross Income

reasonable assurance about whether the Historical Summary is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the Historical Summary. An audit also includes
assessing the basis of accounting used and significant estimates made by
management, as well as evaluating the overall presentation of the Historical
Summary. We believe that our audit provides a reasonable basis for our opinion.
 
    The accompanying Historical Summary was prepared for the purpose of
complying with the rules and regulations of the Securities and Exchange
Commission for inclusion in the Registration Statement on Form S-11 of Beacon
Capital Partners, Inc. as described in Note 1, and is not intended to be a
complete presentation of The Athenaeum Portfolio's revenues and expenses.
 
    In our opinion, the Historical Summary referred to above presents fairly, in
all material respects, the gross income and direct operating expenses described
in Note 1 of The Athenaeum Portfolio for the year ended December 31, 1997, in
conformity with generally accepted accounting principles.

    Presented herein is the combined historical summary ("Historical Summary")
of gross income and direct operating expenses of the following properties, held
under common control (collectively, "The Athenaeum Portfolio"):

    The mixed-use properties were acquired by Beacon Capital Partners, Inc. on
May 1, 1998.
 
    The accompanying Historical Summary has been prepared in accordance with
Rule 3-14 of Regulation S-X of the Securities and Exchange Commission for
inclusion in the Registration Statement on Form S-11 of Beacon Capital Partners,
Inc. Accordingly, certain historical expenses which may not be comparable to the
expenses expected to be incurred in the proposed future operations of The
Athenaeum Portfolio have been excluded. Excluded expenses consist of
depreciation and amortization, and interest not directly related to the future
operations of The Athenaeum Portfolio.
 
    Rental income is recognized on a straight line basis over the term of the
related leases.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

    We have audited the accompanying Historical Summary of Gross Income and
Direct Operating Expenses (the "Historical Summary") for Technology Square and
The Draper Building owned by Asahi Seimei-Prudential Associates, Number Three
for the year ended December 31, 1997. This Historical Summary is the
responsibility of Technology Square and The Draper Building's management. Our
responsibility is to express an opinion on the Historical Summary based on our
audit.
    
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the Historical Summary is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the Historical Summary. An audit also includes
assessing the basis of accounting used and significant estimates made by

Summary. We believe that our audit provides a reasonable basis for our opinion.

                         AND DIRECT OPERATING EXPENSES
                 FOR TECHNOLOGY SQUARE AND THE DRAPER BUILDING
                             (DOLLARS IN THOUSANDS)
 
1. GENERAL INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    Asahi Seimei-Prudential Associates, Number Three (the "Joint Venture") owns
five office buildings, two garages leased to two tenants and land with a surface
parking lot located in Cambridge, Massachusetts (collectively, "Technology
Square and The Draper Building"). Asahi International Ltd. and The Prudential
Insurance Company of America ("Prudential") are the Joint Venture Partners and
each have a 50% interest in the Joint Venture.
 
    The accompanying Historical Summary has been prepared in accordance with
Rule 3-14 of Regulation S-X of the Securities and Exchange Commission for
inclusion in the Registration Statement on Form S-11 of Beacon Capital Partners,
Inc. Accordingly, certain historical expenses which may not be comparable to the
expenses expected to be incurred in the proposed future operations of Technology
Square and The Draper Building have been excluded. Excluded expenses consist of
depreciation and amortization, interest and asset management costs not directly
related to the future operations of Technology Square and The Draper Building.
 
    Rental income is recognized on a straight line basis over the term of the
related leases.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amount reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
2. LEASES
 
    The Joint Venture, as lessor, has entered into non-cancelable operating
leases at Technology Square and The Draper Building. Minimum future rentals

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of
Beacon Capital Partners, Inc.
 
   
    We have audited the accompanying Combined Historical Summary of Gross Income
and Direct Operating Expenses (the "Historical Summary") for Brandywine Place,
Crosspoint Atrium, Forest Abrams Place, 6500 Greenville Avenue, Northcreek Place
II, One Glen Lakes, Park North Business Center, Plaza at Walnut Hill, Richardson
Business Center, Richardson Commerce Centre, Sherman Tech, T.I. Business Park
and Venture Drive Tech Center (collectively, know as "The Breunig Portfolio")
for the year ended December 31, 1997. This Historical Summary is the
responsibility of The Breunig Portfolio's management. Our responsibility is to
express an opinion on the Historical Summary based on our audit.
    
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the Historical Summary is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the Historical Summary. An audit also includes
assessing the basis of accounting used and significant estimates made by
management, as well as evaluating the overall presentation of the Historical
Summary. We believe that our audit provides a reasonable basis for our opinion.
 
   
    The accompanying Historical Summary was prepared for the purpose of
complying with the rules and regulations of the Securities and Exchange
Commission for inclusion in the Registration Statement on Form S-11 of Beacon
Capital Partners, Inc. as described in Note 1, and is not intended to be a
complete presentation of The Breunig Portfolio's revenues and expenses.
    
 
    In our opinion, the Historical Summary referred to above presents fairly, in
all material respects, the gross income and direct operating expenses described
in Note 1 of The Breunig Portfolio for the year ended December 31, 1997, in
conformity with generally accepted accounting principles.

1. GENERAL INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    Presented herein is the combined historical summary ("Historical Summary")
of gross income and direct operating expenses of the following properties,
(collectively, "The Breunig Portfolio") all of which are located in or near
Dallas, Texas:

Park North Business Center
</TABLE>
    
 
    The mixed-use properties were acquired by Beacon Capital Partners, Inc. on
July 1, 1998.
 
    The accompanying Historical Summary has been prepared in accordance with
Rule 3-14 of Regulation S-X of the Securities and Exchange Commission for
inclusion in the Registration Statement on Form S-11 of Beacon Capital Partners,
Inc. Accordingly, certain historical expenses which may not be comparable to the
expenses expected to be incurred in the proposed future operations of The
Breunig Portfolio have been excluded. Excluded expenses consist of depreciation
and amortization, and interest not directly related to the future operations of
The Breunig Portfolio.
 
   
    During 1997, Breunig Commercial purchased Park North Business Center and
Forest Abrams Place. These properties were owned for three months and six months
of 1997, respectively. Partial year financial information is presented within
the Historical Summary for the two properties. In addition, on July 1, 1998,
Breunig acquired one additional property referred to as Bank One LBJ. No
financial information with respect to this property is presented within the
accompanying Historical Summary. Inclusion of these three properties for the
months prior to their acquisition in the accompanying Historical Summary would
not have resulted in a material change to the amounts presented.
    
 
    Rental income is recognized on a straight line basis over the term of the
related leases.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amount reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

ITEM 34. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The MGCL permits a Maryland corporation to include in its charter a
provision limiting the liability of its directors and officers to the
corporation and its stockholders for money damages except for liability result
from (a) actual receipt of an improper benefit or profit in money, property or
services or (b) active and deliberate dishonesty established by a final judgment
as being material to the cause of action. The Charter contains such a provision
which eliminates such liability to the maximum extent permitted by the MGCL.
 
    The Charter authorizes BCP, to the maximum extent permitted by Maryland law,
to obligate itself to indemnify and to pay or reimburse reasonable expenses in
advance of final disposition of a proceeding to (a) any present or former
director or officer or (b) any individual who, while a director of BCP and at
the request of BCP serves or has served another corporation, real estate
investment trust, partnership, joint venture, trust, employee benefit plan or
any other enterprise as a director, officer, partner or trustee of such
corporation, real estate investment trust, partnership, joint venture, trust,
employee benefit plan or other enterprise from and against any claim or
liability to which such person may become subject or which such person may incur
by reason of his or her status as a present or former director or officer of
BCP. The Bylaws obligate BCP, to the maximum extent permitted by Maryland law,
to indemnify and, without requiring a preliminary determination of the ultimate
entitlement to indemnification, to pay or reimburse reasonable expenses in
advance of final disposition of a proceeding to (a) any present or former
director or officer who is made a party to the proceeding by reason of his
service in that capacity or (b) any individual who, while a director of BCP and
at the request of BCP, serves or has served another corporation, real estate
investment trust, partnership, joint venture, trust, employee benefit plan or
any other enterprise as a director, officer, partner or trustee of such
corporation, real estate investment trust, partnership, joint venture, trust,
employee benefit plan or other enterprise and who is made a party to the
proceeding by reason of his service in that capacity. The Charter and Bylaws
also permit BCP to indemnify and advance expenses to any person who served a
predecessor of BCP in any of the capacities described above. Under the Bylaws,
if a claim for indemnification or advancement of expenses by a director or
officer is not paid in full by BCP within (a) 60 days after the receipt by BCP
of a written claim for indemnification or (b) in the case of a director, 10 days
after the receipt by BCP of documentation of expenses and the required
 
                                      II-2
<PAGE>
undertaking, such director or officer may at any time thereafter bring suit
against BCP to recover the unpaid amount of the claim, and if successful in
whole or in part, such director or officer is also entitled to be paid the
expenses of prosecuting such claim. The Bylaws permit BCP to maintain (and it
does maintain) insurance, at its expense, to protect itself and any director,
officer, or non-officer employee against any liability of any character asserted
against or incurred by BCP or any such director, officer, or non-officer
employee, or arising out of any such person's corporate status, whether or not
BCP would have the power to indemnify such person against such liability under
the MGCL or the Bylaws.
 
    The MGCL requires a corporation (unless its charter provides otherwise,
which the Charter does not) to indemnify a director or officer who has been
successful, on the merits or otherwise, in the defense of any proceeding to
which his is made a party by reason of his service in that capacity. The MGCL
permits a corporation to indemnify its present and former directors and
officers, among others, against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by them in connection with any proceeding
to which they may be made a party by reason of their service in those or other
capacities unless it is established that (a) the act or omission of the director
or officer was material to the matter giving rise to the proceeding and (i) was
committed in bad faith or (ii) was the result of active and deliberate
dishonesty, (b) the director or officer actually received an improper personal
benefit in money, property or services or (c) in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act
or omission was unlawful. However, under the MGCL, a Maryland corporation may
not indemnify for an adverse judgment in a suit by or in the right of the
corporation or for a judgment of liability on the basis that personal benefit
was improperly received, whether or not received in the director's or officer's
official capacity, unless in either case a court orders indemnification and then
only for expenses. In addition, the MGCL permits a corporation to advance
reasonable expenses to a director or officer upon the corporation's receipt of
(a) a written affirmation by the director or officer of his good belief that he
has met the standard of conduct necessary for indemnification by the corporation
and (b) a written undertaking by or on his behalf to repay the amount paid or
reimbursed by the corporation if it shall ultimately be determined that the
standard of conduct was not met. Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors, officers or
persons controlling BCP pursuant to the foregoing provisions, BCP has been
informed that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is therefore unenforceable.
 
    BCP has entered into indemnification agreements with each of its directors
and senior officers. The indemnification agreements require, among other
matters, that BCP indemnify its directors and officers, as well as their spouses
and children, to the fullest extent permitted by Maryland law and advance to the
directors and officers all related expenses, subject to reimbursement if it is
subsequently determined that indemnification is not permitted. Under these
agreements, BCP must also indemnify and advance all expenses incurred by
directors and officers seeking to enforce their rights under the indemnification
agreements or recovery under any directors' and officers' liability insurance
policies maintained by BCP.. BCP is not required to indemnify the director or
officer for amounts paid or to be paid in settlement unless such settlement is
approved in advance by BCP. The agreements also require BCP to provide to the
directors or officers the maximum amount of directors' and officers' liability
insurance available under any insurance policy or policies maintained by BCP,
and to continue such coverage for seven years after the directors or officers no
longer serve as directors or officers of BCP for events occurring during their
service with BCP.
 
    Under Section 8 of the Purchase Agreement filed as Exhibit 1.1 hereto, the
Initial Purchaser has agreed to indemnify, under certain conditions, BCP, its
directors, officers, employees and persons who control BCP within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act against
certain losses, claims, damages, liabilities or expenses.

ITEM 37. UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
   
    The undersigned registrant hereby undertakes:
    
 
       (1) For purposes of determining any liability under the Securities Act of
           1933, the information omitted from the form of prospectus filed as
           part of this Registration Statement in reliance upon Rule 430A and
           contained in a form of prospectus filed by the registrant pursuant to
           Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
           deemed to be part of this Registration Statement as of the time it
           was declared effective.
 
       (2) For the purpose of determining any liability under the Securities Act
           of 1933, each post-effective amendment that contains a form of
           prospectus shall be deemed to be a new registration statement
           relating to the securities offered therein, and the offering of such
           securities at that time shall be deemed to be the initial bona fide
           offering thereof.
 
   
       (3) To file during any period in which offers or sales are being made, a
           post-effective amendment to this registration statement;
    
 
   
       (i) To include any prospectus required by Section 10(a)(3) of the
           Securities Act of 1933;
    
 
   
       (ii) To reflect in the prospectus any facts or events arising after the
           effective date of the registration statement (or the most recent
           post-effective amendment thereof) which individually or in the
           aggregate, represent a fundamental change in the information set
           forth in the registration statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high end of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the Commission pursuant to Rule 424(b) if, in
           the aggregate, the changes in volume and price represent no more than
           20 percent change in the maximum aggregate offering price set forth
           in the "Calculation of Registration Fee" table in the effective
           registration statement; and
    
 
   
       (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement.
    
 
   
       (4) To remove from registration by means of a post-effective amendment
           any of the securities being registered which remain unsold at the
           termination of the offering.

                          BEACON CAPITAL PARTNERS, L.P.


         THIS AGREEMENT OF LIMITED PARTNERSHIP OF BEACON CAPITAL
PARTNERS, L.P. (this "Agreement"), dated as of March 16, 1998, is entered into
by and among Beacon Capital Partners, Inc., a Maryland corporation (the
"Company"), and the Persons (as defined below) whose names are set forth on
Exhibit A attached hereto (as it may be amended from time to time).

         WHEREAS, by this Agreement, the Company, as general partner, and the
Persons whose names are set forth on Exhibit A attached hereto, hereby form a
limited partnership pursuant to the laws of the State of Delaware;

         NOW, THEREFORE, BE IT RESOLVED, that for good and adequate
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                            ARTICLE 1 - DEFINED TERMS

         The following definitions shall be for all purposes, unless otherwise
clearly indicated to the contrary, applied to the terms used in this Agreement.

         "Act" means the Delaware Revised Uniform Limited Partnership Act, as it
may be amended from time to time, and any successor to such statute.

         "Additional Limited Partner" means a Person admitted to the Partnership
as a Limited Partner pursuant to Sections 4.2 and 12.2 hereof and who is shown
as such on the books and records of the Partnership.

         "Adjusted Capital Account" means the Capital Account maintained for
each Partner as of the end of each Partnership taxable year (i) increased by any
amounts which such Partner is obligated to restore pursuant to any provision of
this Agreement or is deemed to be obligated to restore pursuant to the
penultimate sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5);
and (ii) decreased by the items described in Regulations Sections
1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), and 1.704-1(b)(2)(ii)(d)(6).
The foregoing definition of Adjusted Capital Account is intended to comply with
the provisions of Regulations Section 1.704-1(b)(2)(ii)(d) and shall be
interpreted consistently therewith.

         "Adjusted Capital Account Deficit" means, with respect to any Partner,
the deficit balance, if any, in such Partner's Adjusted Capital Account as of
the end of the relevant Partnership taxable year.




<PAGE>



         "Adjusted Property" means any property, the Carrying Value of which has
been adjusted pursuant to Exhibit B hereof.

         "Affiliate" means, with respect to any Person, any Person directly or
indirectly controlling, controlled by or under common control with such Person.
For purposes of this definition, "control," when used with respect to any
Person, means the power to direct the management and policies of such Person,
directly or indirectly, whether through the ownership of voting securities, by
contract or otherwise, and the terms "controlling" and "controlled" have
meanings correlative to the foregoing. No officer, director or stockholder of
the General Partner shall be considered an Affiliate of the General Partner
solely as a result of serving in such capacity or being a stockholder of the
General Partner.

         "Agreed Value" means (i) in the case of any Contributed Property as of
the time of its contribution to the Partnership, the 704(c) Value of such
property, reduced by any liabilities either assumed by the Partnership upon such
contribution or to which such property is subject when contributed, and (ii) in
the case of any property distributed to a Partner by the Partnership, the
Partnership's Carrying Value of such property at the time such property is
distributed, reduced by any liabilities either assumed by such Partner upon such
distribution or to which such property is subject at the time of distribution as
determined under Section 752 of the Code and the Regulations thereunder. The
aggregate Agreed Value of the Contributed Property contributed or deemed
contributed by each Partner as of the date hereof is as set forth in Exhibit A.

         "Agreement" means this Agreement of Limited Partnership, as it may be
amended, supplemented or restated from time to time.

         "Assignee" means a Person to whom one or more Partnership Units have
been transferred in a manner permitted under this Agreement, but who has not
become a Substituted Limited Partner, and who has the rights set forth in
Section 11.5.

         "Available Cash" means, with respect to any period for which such
calculation is being made, (i) the sum of:

                  (a) the Partnership's Net Income or Net Loss (as the case may
         be) for such period (without regard to adjustments resulting from
         allocations described in Sections 1.A through 1.E of Exhibit C);

                  (b) Depreciation and all other noncash charges deducted in
         determining Net Income or Net Loss for such period;

                  (c) the amount of any reduction in the reserves of the
         Partnership referred to in clause (ii)(f) below (including, without
         limitation, reductions resulting because the General Partner determines
         such amounts are no longer necessary);

                                        2

<PAGE>

Adjusted Property, the 704(c) Value of such property or book value of such
property as determined in accordance with Exhibit B hereto, reduced (but not
below zero) by all Depreciation with respect to such Contributed Property or

following the contribution of or adjustment with respect to such Property; and
(ii) with respect to any other Partnership property, the adjusted basis of such
property for federal income tax purposes, all as of the time of determination.
The Carrying Value of any property shall be adjusted from time to time in
accordance with Exhibit B hereof, and to reflect changes, additions or other
adjustments to the Carrying Value for dispositions and acquisitions of
Partnership properties, as deemed appropriate by the General Partner.

         "Cash Amount" means an amount of cash equal to the Value on the
Valuation Date of the REIT Shares Amount; provided, however, in the case of a
redemption of any Incentive Unit pursuant to Section 8.6A, the Cash Amount
attributable to such Incentive Unit being redeemed pursuant to Section 8.6A
shall be reduced to the extent there is insufficient Net Income (and gross
income) to make the maximum allocation provided for in Section 6.2 with respect
to such Incentive Unit. The Cash Amount of the Convertible Unit shall be zero.

Partnership. Once the Carrying Value of a Contributed Property is adjusted
pursuant to Exhibit B hereof, such property shall no longer constitute a
Contributed Property for purposes of Exhibit B hereof, but shall be deemed an
Adjusted Property for such purposes.

         "Conversion Factor" means 1.0, provided that in the event that the
Company (i) declares or pays a dividend on its outstanding REIT Shares in REIT
Shares or makes a distribution to all holders of its outstanding REIT Shares in
REIT Shares; (ii) subdivides its outstanding REIT Shares; or (iii) combines its
outstanding REIT Shares into a smaller number of REIT Shares, the Conversion
Factor shall be adjusted by multiplying the Conversion Factor by a fraction, the
numerator of which shall be the number of REIT Shares issued and outstanding on

(assuming for such purpose that such dividend, distribution, subdivision or
combination has occurred as of such time), and the denominator of which shall be
the actual number of REIT Shares (determined without the above assumption)
issued and outstanding on the record date for such dividend, distribution,
subdivision or combination. Any adjustment to the Conversion Factor shall become
effective immediately after the effective date of such event retroactive to the
record date, if any, for such event (provided, however, if a Notice of
Redemption is given prior to such a record date and the Specified Redemption
Date is after such a record date, then the adjustment to the Conversion Factor
shall, with respect to such redeeming Partner, be retroactive to the date of
such Notice of Redemption). It is intended that adjustments to the Conversion
Factor are to be made in order to avoid unintended dilution or anti-dilution as
a result of transactions in which REIT Shares are issued, redeemed or exchanged
without a corresponding issuance, redemption or exchange of Partnership Units.
If, prior to a Specified Redemption Date, Rights (other than Rights issued
pursuant to an employee benefit plan or other compensation arrangement) were
issued and have expired, and such Rights were issued with an exercise price
that, together with the purchase price for such Rights, was below fair market
value in relation to the security or other property to be acquired upon the
exercise of such Rights, and such Rights were issued to all holders of
outstanding REIT shares or the General Partner cannot in good faith represent
that the issuance of such Rights benefitted the Limited Partners, then the
Conversion Factor applicable upon a Notice of Redemption shall be equitably
adjusted in a manner consistent with antidilution provisions in warrants and
other instruments in the case of such a below market issuance or exercise price.
A similar equitable adjustment to protect the value of Partnership Units shall
be made in all events if any Rights issued under a "Shareholder Rights Plan"
became exercisable and expired prior to a Specified Redemption Date.

         "Convertible Unit" means the Unit referred to in Section 4.4 hereof
which represents solely the right to convert into a certain number of Incentive

in allocations of income or any distributions made to, or with respect to, other
classes of Units.

         "Depreciation" means, for each taxable year, an amount equal to the
federal income tax depreciation, amortization, or other cost recovery deduction

<PAGE>



for such year, except that if the Carrying Value of an asset differs from its
adjusted basis for federal income tax purposes at the beginning of such year or
other period, Depreciation shall be an amount which bears the same ratio to such
beginning Carrying Value as the federal income tax depreciation, amortization,
or other cost recovery deduction for such year bears to such beginning adjusted
tax basis; provided, however, that if the federal income tax depreciation,
amortization, or other cost recovery deduction for such year is zero,
Depreciation shall be determined with reference to such beginning Carrying Value
using any reasonable method selected by the General Partner.

         "Effective Date" means the date of closing of the initial private
offering of REIT Shares by the Company.

value to no par value, or as a result of a split, dividend or similar
subdivision); (iv) any issuance of equity securities of the Company in exchange
for assets (other than an issuance of securities for cash or an issuance of
securities pursuant to an employee benefit plan); (v) any Change of Control (as

                           limited partnership (or a partnership in which the
                           Limited Partners have limited liability) in the State
                           of Delaware and in all other jurisdictions in which
                           the Partnership may or plans to conduct business or
                           own property; (b) all instruments that the General
                           Partner deems appropriate or necessary to reflect any
                           amendment, change, modification or restatement of
                           this Agreement in accordance with its terms; (c) all
                           conveyances and other instruments or documents that
                           the General Partner or the Liquidator deems
                           appropriate or necessary to reflect the dissolution
                           and liquidation of the Partnership pursuant to the
                           terms of this Agreement, including, without
                           limitation, a certificate of cancellation; (d) all
                           instruments relating to the admission, withdrawal,
                           removal or substitution of any Partner pursuant to,
                           or other events described in, Article 11, 12 or 13
                           hereof or the Capital Contribution of any Partner;
                           and (e) all certificates, documents and other
                           instruments relating to the determination of the
                           rights, preferences and privileges of Partnership
                           Interests; and

                  (2)      execute, swear to, seal, acknowledge and file all
                           ballots, consents, approvals, waivers, certificates
                           and other instruments appropriate or necessary, in
                           the sole and absolute discretion of the General
                           Partner or any Liquidator, to make, evidence, give,
                           confirm or ratify any vote, consent, approval,
                           agreement or other action which is made or given by
                           the Partners hereunder or is consistent with the
                           terms of this agreement or appropriate or necessary,
                           in the sole discretion of the General Partner or any
                           Liquidator, to effectuate the terms or intent of this
                           Agreement.

Nothing contained herein shall be construed as authorizing the General Partner
or any Liquidator to amend this Agreement except in accordance with Article 14
hereof or as may be otherwise expressly provided for in this Agreement.

         B. The foregoing power of attorney is hereby declared to be irrevocable
and a power coupled with an interest, in recognition of the fact that each of
the Partners will be relying upon the power of the General Partner and any
Liquidator to act as contemplated by this Agreement in any filing or other
action by it on behalf of the Partnership, and it shall survive and not be
affected by the subsequent Incapacity of any Limited Partner or Assignee and the
transfer of all or any portion of such Limited Partner's or Assignee's
Partnership Units and shall extend to such Limited Partner's or Assignee's
heirs, successors, assigns and personal representatives. Each such Limited
Partner or Assignee hereby agrees to be bound by any representation made by the
General Partner or any Liquidator, acting in good faith

                                       13

<PAGE>



pursuant to such power of attorney, and each such Limited Partner or Assignee
hereby waives any and all defenses which may be available to contest, negate or
disaffirm the action of the General Partner or any Liquidator, taken in good
faith under such power of attorney. Each Limited Partner or Assignee shall
execute and deliver to the General Partner or the Liquidator, within fifteen
(15) days after receipt of the General Partner's or Liquidator's request
therefor, such further designation, powers of attorney and other instruments as
the General Partner or the Liquidator, as the case may be, deems necessary to
effectuate this Agreement and the purposes of the Partnership.

         Section 2.5 Term
                     ----

         The term of the Partnership commenced on March 16, 1998, the date on
which the Certificate of Limited Partnership was filed in the office of the
Secretary of State of the State of Delaware, and shall continue until the
Partnership is dissolved pursuant to the provisions of Article 13 or as
otherwise provided by law.


                               ARTICLE 3 - PURPOSE

         Section 3.1 Purpose and Business
                     --------------------

         The purpose and nature of the business to be conducted by the
Partnership is (i) to conduct any business that may be lawfully conducted by a
limited partnership organized pursuant to the Act; provided, however, that such
business shall be limited to and conducted in such a manner as to permit the
Company at all times to be classified as a REIT, unless the Board of Directors
of the Company determines that it is no longer in the best interests of the
Company to continue to qualify as a REIT; (ii) to enter into any partnership,
joint venture, limited liability company or other similar arrangement to engage
in any of the foregoing or to own interests in any entity engaged, directly or
indirectly, in any of the foregoing; and (iii) to do anything necessary or
incidental to the foregoing. In connection with the foregoing, and without
limiting the Company's right, in its sole discretion, to cease to qualify as a
REIT, the Partners acknowledge the Company's current status as a REIT inures to
the benefit of all of the Partners and not solely the General Partner. The
General Partner shall also be empowered to do any and all acts and things
necessary or prudent to ensure that the Partnership will not be classified as a
"publicly traded partnership" for purposes of Section 7704 of the Code,
including but not limited to imposing restrictions on transfers and restrictions
on redemptions.

         Section 3.2 Powers
                     ------

         The Partnership is empowered to do any and all acts and things
necessary, appropriate, proper, advisable, incidental to or convenient for the
furtherance and accomplishment of the purposes and business described herein and
for the protection and benefit of the Partnership, including, without
limitation, full power and authority, directly or through its ownership

                                       14

<PAGE>



interest in other entities, to enter into, perform and carry out contracts of
any kind, borrow money and issue evidences of indebtedness whether or not
secured by mortgage, deed of trust, pledge or other lien, acquire, own, manage,
improve and develop real property, and lease, sell, transfer and dispose of real
property; provided, however, that the Partnership shall not take, and shall
refrain from taking, any action which, in the judgment of the General Partner,
in its sole and absolute discretion, (i) could adversely affect the ability of
the Company to continue to qualify as a REIT (including by reason of the
Partnership being taxable as a corporation pursuant to Section 7701 or Section
7704 of the Code); (ii) could subject the Company to any liability for
additional taxes under Section 857 or Section 4981 of the Code; or (iii) could
violate any law or regulation of any governmental body or agency having
jurisdiction over the Company or its securities, unless, in the case of each of
clauses (i), (ii) and (iii), such action (or inaction) shall have been
specifically consented to by the General Partner in writing.


                        ARTICLE 4 - CAPITAL CONTRIBUTIONS

         Section 4.1 Capital Contributions of the Partners
                     -------------------------------------

         A. Initial Capital Contributions of the Partnership on the Effective
Date. On the Effective Date, or such later date as the General Partner
determines, the Company, as General Partner and as a Limited Partner, Beacon
Capital Participation Plan, L.P., a Delaware limited partnership ("BCPP, L.P."),
as a Limited Partner, and the other Persons listed on Schedule A will make
Capital Contributions to the Partnership as set forth therein.

         B. General Partnership Interest. A number of Partnership Units held by
the Company equal to one percent (1%) of all outstanding Partnership Units
(exclusive of the Convertible Unit) shall be deemed to be the General Partner
Partnership Units and shall be the General Partnership Interest. All other
Partnership Units held by the Company shall be deemed to be Limited Partnership
Interests and shall be held by the General Partner in its capacity as a Limited
Partner in the Partnership.

         C. Capital Contributions By Merger. To the extent the Partnership
acquires any property by the merger of any other Person into the Partnership,
Persons who receive Partnership Interests in exchange for their interests in the
Person merging into the Partnership shall become Partners and shall be deemed to
have made Capital Contributions as provided in the applicable merger agreement
and as set forth in Exhibit A, as amended to reflect such deemed Capital
Contributions.

         D. No Obligation to Make Additional Capital Contributions. Each Partner
shall own the number of Partnership Units set forth for such Partner in Exhibit
A and shall have a Percentage Interest in the Partnership as set forth in
Exhibit A, which Percentage Interest shall be adjusted in Exhibit A from time to
time by the General Partner to the extent necessary to

                                       15

<PAGE>



reflect accurately redemptions, additional Capital Contributions, the issuance
of additional Partnership Units (pursuant to any merger or otherwise), or
similar events having an effect on any Partner's Percentage Interest. The number
of Partnership Units held by the General Partner, in its capacity as general
partner, (equal to one percent (1%) of all outstanding Partnership Units
(exclusive of the Convertible Unit) from time to time) shall be deemed to be the
General Partner Interest. Except as provided in Sections 4.2, 5.4 or 10.5, or
elsewhere in this Agreement, the Partners shall have no obligation to make any
additional Capital Contributions or loans to the Partnership.

         E. On the Effective Date, BCPP, L.P. shall be issued, in connection
with its purchase of Units and Capital Contribution to the Partnership and for
no additional consideration, Limited Partner Interests which shall have the
rights set forth in Section 4.4 hereof, and which Limited Partner Interests
shall represent a separate and distinct class of Unit of Limited Partner
Interests (the "Convertible Unit").

         Section 4.2 Issuances of Additional Partnership Interests
                     ---------------------------------------------

         A. The General Partner is hereby authorized to cause the Partnership
from time to time to issue to the Partners (including the General Partner and
its Affiliates) or other Persons (including, without limitation, in connection
with the contribution of property to the Partnership) additional Partnership
Units or other Partnership Interests in one or more classes, or one or more
series of any of such classes, with such designations, preferences and relative,
participating, optional or other special rights, powers and duties, including
rights, powers and duties senior to the Limited Partner Interests issued on the
Effective Date, all as shall be determined by the General Partner in its sole
and absolute discretion subject to Delaware law, including, without limitation,
(i) the allocations of items of Partnership income, gain, loss, deduction and
credit to each such class or series of Partnership Interests; (ii) the right of
each such class or series of Partnership Interests to share in Partnership
distributions; and (iii) the rights of each such class or series of Partnership
Interests upon dissolution and liquidation of the Partnership; provided that no
such additional Partnership Units or other Partnership Interests shall be issued
to the General Partner, unless either (a)(1) the additional Partnership
Interests are issued in connection with the grant, award or issuance of REIT
Shares or other equity interests by the Company, which REIT shares or other
equity interests have designations, preferences and other rights such that the
economic interests attributable to such REIT shares or other equity interests
are substantially similar to the designations, preferences and other rights of
the additional Partnership Interests issued to the General Partner in accordance
with this Section 4.2.A, and (2) the Company shall make a Capital Contribution
to the Partnership in an amount equal to the proceeds raised in connection with
such issuance, or (b) the additional Partnership Interests are issued to all
Partners in proportion to their respective Percentage Interests. In addition,
the Company may acquire Units from other Partners pursuant to this Agreement. In
the event that the Partnership issues Partnership Interests pursuant to this
Section 4.2.A, the General Partner shall make such revisions to this Agreement
(without any requirement of receiving approval of the Limited Partners)
including

                                       16

<PAGE>



but not limited to the revisions described in Section 5.5 hereof, as it deems
necessary to reflect the issuance of such additional Partnership Interests and
the special rights, powers and duties associated therewith. Unless specifically
set forth otherwise by the General Partner, any Partnership Interest issued
after the Effective Date shall have the same rights, powers and duties as the
Partnership Interests issued on the Effective Date.

         B. From and after the date hereof, the Company shall not issue any
additional REIT Shares (other than REIT Shares issued pursuant to Section 8.6),
or rights, options, warrants or convertible or exchangeable securities
containing the right to subscribe for or purchase REIT Shares (collectively "New
Securities") other than to all holders of REIT Shares unless (i) the General
Partner shall cause the Partnership to issue to the Company, Partnership
Interests or rights, options, warrants or convertible or exchangeable securities
of the Partnership having designations, preferences and other rights, all such
that the economic interests are substantially similar to those of the New
Securities; and (ii) the Company contributes to the Partnership the proceeds
from the issuance of such New Securities and from the exercise of rights
contained in such New Securities. Without limiting the foregoing, the Company is
expressly authorized to issue New Securities for no tangible value or for less
than fair market value, and the General Partner is expressly authorized to cause
the Partnership to issue to the Company corresponding Partnership Interests, so
long as (x) the General Partner concludes in good faith that such issuance is in
the interests of the Company and the Partnership (for example, and not by way of
limitation, the issuance of REIT Shares and corresponding Units pursuant to an
employee stock purchase plan providing for employee grants or purchases of REIT
Shares or employee stock options that have an exercise price that is less than
the fair market value of the REIT Shares, either at the time of issuance or at
the time of exercise); and (y) the Company contributes all proceeds, if any,
from such issuance and exercise to the Partnership.

         Section 4.3 Contribution of Proceeds of Issuance of REIT Shares
                     ---------------------------------------------------

         In connection with the initial offering of REIT Shares by the Company
and any other issuance of New Securities pursuant to Section 4.2, the Company
shall contribute to the Partnership any proceeds (or a portion thereof) raised
in connection with such issuance; provided that if the proceeds actually
received by the Company are less than the gross proceeds of such issuance as a
result of any expenses paid or incurred in connection with such issuance, then
the Company shall be deemed to have made a Capital Contribution to the
Partnership in the amount equal to the sum of the net proceeds of such issuance
plus the amount of such other expenses paid by the Company (which expense shall
be treated as an expense for the benefit of the Partnership for purposes of
Section 7.4); provided however that the cost of the discount to NationsBanc
Montgomery Securities LLC as underwriter in connection with the initial offering
of REIT Shares by the Company (including any REIT Shares sold pursuant to the
overallotment option) shall be borne by the Company, and the Company shall not
be deemed to have made a Capital Contribution to the Partnership in an amount
equal to costs attributable thereto. In the case of employee acquisitions of New
Securities at a discount from fair market

                                       17

<PAGE>



value or for no value in connection with a grant of New Securities, the amount
of such discount representing compensation to the employee, as determined by the
General Partner, shall be treated as an expense of the Partnership of the
issuance of such New Securities.

         Section 4.4 Convertible Unit and Incentive Units
                     ------------------------------------

         A Convertible Unit shall be issued to BCPP, L.P. on the Effective Date
for no additional consideration. At the end of the three year period following
the completion of the first calendar year following the Effective Date (the
"Determination Date"), the Convertible Unit shall automatically convert into a
number of Incentive Units (as defined herein) having an aggregate fair market
value equal to the Incentive Return (as defined herein). For purposes of the
foregoing, each such Incentive Unit shall be deemed to have a value equal to the
value of a REIT Share on a one-for-one basis, appropriately adjusted to reflect
any adjustments to the Conversion Factor.

         A. The "Incentive Return" shall equal the product of (A) 12% of the
dollar amount by which (i) the Actual Return exceeds (ii) the Base Return;
multiplied by (B) the weighted average of shares of common stock of the Company
("Common Stock") and Units (other than the Convertible Unit) outstanding for the
12 months immediately preceding the Determination Date; multiplied by (C) the
Company's Multiple (as defined below).

         For the purposes of calculating the Incentive Return:

                  "Actual Return" means the Funds from Operations (before the
         Incentive Return) per share of Common Stock and per Unit for the 12
         months immediately preceding the Determination Date;

                  "Base Return" means an amount equal to what the Funds from
         Operations per share of Common Stock and per Unit would have been for
         the twelve month period immediately preceding the Determination Date
         assuming a benchmark cumulative rate of return on the offering price of
         the Company's initial private offering (the "Offering Price") equal to
         10% per annum, compounding quarterly, calculated since the beginning of
         the calendar quarter following the date of closing of the Effective
         Date;

                  "Funds from Operations"means net income per share of Common
         Stock and per Unit (computed in accordance with GAAP), excluding gains
         (or losses) from debt restructuring and sales of property, plus
         depreciation and amortization (in each case, only real estate-related
         assets), and after adjustments for unconsolidated partnerships and
         joint ventures; and

                  "Multiple" means the price of the Company's Common Stock (as
         defined below) divided by the Company's Funds from Operations for the
         fiscal quarter ending on the Determination Date on an annualized basis.

                                       18

<PAGE>



                  For the purposes of calculating the Multiple, the price of the
         Company's Common Stock will be calculated as follows:

                           (1) Where there exists a public market for the
                  Company's Common Stock, the price of the Company's Common
                  Stock will be the average of the closing bid and asked prices
                  of the Common Stock quoted in the Over-The-Counter Market
                  Summary or the last reported sale price of the Common Stock or
                  the closing price quoted on the NASDAQ System or on any
                  exchange on which the Common Stock is listed, whichever is
                  applicable, as published in The Wall Street Journal for the
                  ninety (90) days prior to the calculation of the Multiple.

                           (2) If no public market for the Common Stock exists
                  at the time of such exercise, the price of the Company's
                  Common Stock will be determined by a single, independent
                  appraiser to be selected by a committee of directors of the
                  Company who are not employees of the Company ("Independent
                  Directors"), which appraiser shall appraise the fair market
                  value of one share of the Company's Common Stock within thirty
                  (30) days of its selection within such guidelines as shall be
                  determined by the committee of Independent Directors.

         B. In the event of a change in control of the Company (as such term is
defined in the Company's Certificate of Incorporation), the right to convert the
Convertible Unit shall automatically accelerate and the determination of the
Incentive Return shall be appropriately amended or adjusted to reflect such
acceleration as determined in the discretion of the Company's Compensation
Committee. The Company anticipates that the mechanism by which the Incentive
Return will be adjusted as a result of a change of control shall be established
by the Compensation Committee in advance of any such event.

         C. The Incentive Units shall be a class of Units of Limited Partner
Interests issuable upon the conversion of the Convertible Unit and, upon
issuance, the Incentive Units (i) shall share with the other then outstanding
Units in allocations and distributions by the Partnership as provided for in
Articles 5 and 6 and (ii) shall be redeemable as provided for in Section 8.6.

         Section 4.5 Capital Account Balances
                     ------------------------

         The Capital Account balance, as of the Effective Date, or such later
date as provided for in Section 4.1A, attributable to each Partner and the
number of Units held by each Partner is reflected on Exhibit A. As of the
Effective Date, the Capital Account balances of the Partners will be in
proportion to their Percentage Interests and the Capital Account balance
allocable to each Unit (other than the Convertible Unit) will be equal. The
Capital Account balance allocable to the Convertible Unit will be zero at all
times and the Capital Account balance allocable to any Incentive Units, as of
the time of their issuance pursuant to Section

                                       19

<PAGE>



4.4, will also be zero. Except as otherwise determined in good faith by the
General Partner, allocations of Net Income (or gross income) pursuant to Section
6.2 shall be allocated to the Capital Account balance attributable to the
Incentive Units being redeemed or liquidated, distributions in redemption or
liquidation of Units shall be allocated to the Capital Account balances
attributable to the Units being redeemed or liquidated, and other allocations
and distributions shall be allocated to the Capital Account balances
attributable to the appropriate Units which shall generally be in equal amounts
to each outstanding Unit.


                            ARTICLE 5 - DISTRIBUTIONS

         Section 5.1 Requirement and Characterization of Distributions
                     -------------------------------------------------

         The General Partner shall distribute at least quarterly an amount equal
to one hundred percent (100%) of Available Cash generated by the Partnership
during such quarter or shorter period to the Partners who are Partners on the
Partnership Record Date in accordance with their respective Percentage Interests
on such Partnership Record Date; provided that in no event may a Partner receive
a distribution of Available Cash with respect to a Partnership Unit if such
Partner is entitled to receive a distribution out of such Available Cash with
respect to a REIT Share for which such Partnership Unit has been exchanged and
such distribution shall be made to the Company. Unless otherwise expressly
provided for herein or in an agreement at the time a new class of Partnership
Interests is created in accordance with Article 4 hereof, no Partnership
Interest shall be entitled to a distribution in preference to any other
Partnership Interest.

         Section 5.2 Amounts Withheld
                     ----------------

         All amounts withheld pursuant to the Code or any other provisions of
law with respect to any allocation, payment or distribution to the Partners or
Assignees shall be treated as a loan pursuant to the provisions of Section 10.5.

         Section 5.3 Distributions Upon Liquidation
                     ------------------------------

         In the event the Partnership (or a Partner's interest therein) is
"liquidated" within the meaning of Treasury Regulations Section
1.704-1(b)(2)(ii)(g), then any distributions shall be made pursuant to this
Section 5.3 to the Partners (or such Partner, as appropriate), in accordance
with their positive Capital Account balances in compliance with Treasury
Regulations Section 1.704-1(b)(2)(ii)(b)(2).

         Section 5.4 Deficit Restoration by General Partner
                     --------------------------------------

         In the event the General Partner's interest in the Partnership is
"liquidated" within the meaning of Treasury Regulations Section
1.704-1(b)(2)(ii)(g) (including, without limitation,

                                       20

<PAGE>



upon the liquidation of the Partnership) and the General Partner's Capital
Account has a deficit balance after giving effect to all contributions,
distributions and allocations for all taxable years, including the year during
which such liquidation occurs, the General Partner shall contribute to the
capital of the Partnership the amount necessary to restore such deficit balance
to zero in compliance with Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(3).

         Section 5.5 Revisions to Reflect Issuance of Additional Partnership
                     -------------------------------------------------------
                     Interests
                     ---------

         In the event that the Partnership issues additional Partnership
Interests to the General Partner, any existing Limited Partner or any Additional
Limited Partner pursuant to Article 4 hereof, the General Partner shall make
such revisions to this Agreement and any Exhibits attached hereto as it deems
necessary to reflect the issuance of such additional Partnership Interests and
any special rights, duties or powers with respect thereto.


                             ARTICLE 6 - ALLOCATIONS

         Section 6.1 Allocations For Capital Account Purposes
                     ----------------------------------------

notwithstanding any other provision of this Agreement (except as provided in
Section 7.3 or Section 8.7), the Act or any applicable law, rule or regulation,
to the fullest extent permitted under the Act or other applicable law, rule or
regulation. The execution, delivery or performance by the General Partner or the
Partnership of any agreement authorized or permitted under this Agreement shall

reasonable from time to time.

         D. In exercising its authority under this Agreement, the General
Partner may, but shall be under no obligation to, take into account the tax
consequences to any Partner of any action taken by it. The General Partner and

of Section 7.3 and Section 8.7. The Limited Partners expressly acknowledge that
the General Partner is acting on behalf of the Partnership, the Company and the
Company's stockholders collectively.

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

         The General Partner has previously filed the Certificate of Limited
Partnership with the Secretary of State of the State of Delaware as required by

appropriate for the formation, continuation, qualification and operation of a
limited partnership (or a partnership in which the limited partners have limited
liability) in the State of Delaware and any other state, or the District of
Columbia, in which the Partnership may elect to do business or own property. To
the extent that such action is determined by the General Partner to be
reasonable and necessary or appropriate, the General Partner shall file
amendments to and restatements of the Certificate of Limited Partnership and do
all of the things to maintain the Partnership as a limited partnership (or a
partnership in which the limited partners have limited liability) under the laws
of the State of Delaware and each other state, or the District of Columbia, in
which the Partnership may elect to do business or own property. Subject to the
terms of Section 8.5.A(4) hereof, the General Partner shall not be required,
before or after filing, to deliver or mail a copy of the Certificate of Limited
Partnership or any amendment thereto to any Limited Partner.

         B. The General Partner shall be reimbursed on a monthly basis, or such
other basis as it may determine in its sole and absolute discretion, for all
expenses that it incurs relating to the ownership and operation of, or for the
benefit of, the Partnership (including, without limitation, (i) expenses
relating to the ownership of interests in and operation of the Partnership, (ii)
compensation of the Company's officers and employees including, without
limitation, payments under the General Partner's Stock Incentive Plans that

of any such reimbursement shall be reduced by any interest earned by the General
Partner with respect to bank accounts or other instruments or accounts held by
it on behalf of the Partnership. The Partners acknowledge that all such expenses
of the General Partner are deemed to be for the benefit of the Partnership. Such
reimbursement shall be in addition to any reimbursement made as a result of
indemnification pursuant to Section 7.7 hereof.

         C. In the event that the Company shall elect to purchase from its
shareholders REIT Shares for the purpose of delivering such REIT Shares to
satisfy an obligation under any dividend reinvestment program adopted by the
Company, any employee stock purchase plan adopted by the Company, or any similar
obligation or arrangement undertaken by the Company in the future or for the
purpose of retiring such REIT Shares, the purchase price paid by the Company for
such REIT Shares and any other expenses incurred by the Company in connection
with such purchase shall be considered expenses of the Partnership and shall be
advanced to the Company or reimbursed to the Company, subject to the condition
that: (i) if such REIT Shares subsequently are sold by the Company, the Company
shall pay to the Partnership any proceeds received by the Company for such REIT
Shares (which sales proceeds shall include the amount of dividends reinvested
under any dividend reinvestment or similar program provided that a transfer of
REIT Shares for Units pursuant to Section 8.6 would not be considered a sale for
such purposes); and (ii) if such REIT Shares are not retransferred by the
Company within thirty (30) days after the purchase thereof, or the

                                       27

<PAGE>



Company otherwise determines not to retransfer such REIT Shares, the Company, as
General Partner, shall cause the Partnership to redeem a number of Partnership
Units held by the Company, as a Limited Partner, equal to the product obtained
by dividing the number of such REIT Shares by the Conversion Factor (in which
case such advancement or reimbursement of expenses shall be treated as having
been made as a distribution in redemption of such number of Units held by the
Company).

         Section 7.5 Outside Activities of the General Partner
                     -----------------------------------------

         The General Partner shall not directly or indirectly enter into or
conduct any business other than in connection with the ownership, acquisition
and disposition of Partnership Interests and the management of the business of
the Partnership, and such activities as are incidental thereto. The General
Partner and any Affiliates of the General Partner may acquire Limited Partner
Interests and shall be entitled to exercise all rights of a Limited Partner
relating to such Limited Partner Interests.

         Section 7.6 Contracts with Affiliates
                     -------------------------

         A. The Partnership may lend or contribute funds or other assets to its
Subsidiaries or other Persons in which it has an equity investment and such
Persons may borrow funds from the Partnership, on terms and conditions
established in the sole and absolute discretion of the General Partner. The
foregoing authority shall not create any right or benefit in favor of any
Subsidiary or any other Person.

         B. Except as provided in Section 7.5, the Partnership may transfer
assets to joint ventures, other partnerships, corporations or other business
entities in which it is or thereby becomes a participant upon such terms and
subject to such conditions consistent with this Agreement and applicable law as
the General Partner, in its sole and absolute discretion, believes are
advisable.

         C. Except as expressly permitted by this Agreement, neither the General
Partner nor any of its Affiliates shall sell, transfer or convey any property
to, or purchase any property from, the Partnership, directly or indirectly,
except pursuant to transactions that are determined by the General Partner in
good faith to be fair and reasonable.

         D. The General Partner, in its sole and absolute discretion and without
the approval of the Limited Partners, may propose and adopt, on behalf of the
Partnership, employee benefit plans, stock option plans, and similar plans
funded by the Partnership for the benefit of employees of the General Partner,
the Partnership, Subsidiaries of the Partnership or any Affiliate of any of them
in respect of services performed, directly or indirectly, for the benefit of the
Partnership, the General Partner, or any Subsidiaries of the Partnership.


                                       28

<PAGE>



         E. The General Partner is expressly authorized to enter into, in the
name and on behalf of the Partnership, certain conflict avoidance agreements
with various Affiliates of the Partnership and the General Partner, on such
terms as the General Partner, in its sole and absolute discretion, believes are
advisable.

         Section 7.7 Indemnification
                     ---------------

         A. To the fullest extent permitted by Delaware law, the Partnership
shall indemnify each Indemnitee from and against any and all losses, claims,
damages, liabilities, joint or several, expenses (including, without limitation,
attorneys fees and other legal fees and expenses), judgments, fines,
settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the Partnership or the Company as set forth in
this Agreement, in which such Indemnitee may be involved, or is threatened to be
involved, as a party or otherwise, unless it is established that: (i) the act or
omission of the Indemnitee was material to the matter giving rise to the
proceeding and either was committed in bad faith or was the result of active and
deliberate dishonesty; (ii) the Indemnitee actually received an improper
personal benefit in money, property or services; or (iii) in the case of any
criminal proceeding, the Indemnitee had reasonable cause to believe that the act
or omission was unlawful. Without limitation, the foregoing indemnity shall
extend to any liability of any Indemnitee, pursuant to a loan guaranty (except a
guaranty by a limited partner of nonrecourse indebtedness of the Partnership or
as otherwise provided in any such loan guaranty) or otherwise for any
indebtedness of the Partnership or any Subsidiary of the Partnership (including
without limitation, any indebtedness which the Partnership or any Subsidiary of
the Partnership has assumed or taken subject to), and the General Partner is
hereby authorized and empowered, on behalf of the Partnership, to enter into one
or more indemnity agreements consistent with the provisions of this Section 7.7
in favor of any Indemnitee having or potentially having liability for any such
indebtedness. The termination of any proceeding by conviction of an Indemnitee
or upon a plea of nolo contendere or its equivalent by an Indemnitee, or an
entry of an order of probation against an Indemnitee prior to judgment, creates
a rebuttable presumption that such Indemnitee acted in a manner contrary to that
specified in this Section 7.7.A. Any indemnification pursuant to this Section
7.7 shall be made only out of the assets of the Partnership, and neither the
General Partner nor any Limited Partner shall have any obligation to contribute
to the capital of the Partnership, or otherwise provide funds, to enable the
Partnership to fund its obligations under this Section 7.7.

         B. Reasonable expenses incurred by an Indemnitee who is a party to a
proceeding shall be paid or reimbursed by the Partnership in advance of the
final disposition of the proceeding upon receipt by the Partnership of (i) a
written affirmation by the Indemnitee of the Indemnitee's good faith belief that
the standard of conduct necessary for indemnification by the Partnership as
authorized in Section 7.7.A. has been met, and (ii) a written undertaking by or
on behalf of the Indemnitee to repay the amount if it shall ultimately be
determined that the standard of conduct has not been met.

                                       29

<PAGE>



         C. The indemnification provided by this Section 7.7 shall be in
addition to any other rights to which an Indemnitee or any other Person may be
entitled under any agreement, pursuant to any vote of the Partners, as a matter
of law or otherwise, and shall continue as to an Indemnitee who has ceased to
serve in such capacity unless otherwise provided in a written agreement pursuant
to which such Indemnitee is indemnified.

         D. The Partnership may, but shall not be obligated to, purchase and
maintain insurance, on behalf of the Indemnitees and such other Persons as the
General Partner shall determine, against any liability that may be asserted
against or expenses that may be incurred by such Person in connection with the
Partnership's activities, regardless of whether the Partnership would have the
power to indemnify such Person against such liability under the provisions of
this Agreement.

         E. For purposes of this Section 7.7, the Partnership shall be deemed to
have requested an Indemnitee to serve as fiduciary of an employee benefit plan
whenever the performance by it of its duties to the Partnership also imposes
duties on, or otherwise involves services by, it to the plan or participants or
beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect
to an employee benefit plan pursuant to applicable law shall constitute fines
within the meaning of Section 7.7; and actions taken or omitted by the
Indemnitee with respect to an employee benefit plan in the performance of its
duties for a purpose reasonably believed by it to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is not opposed to the best interests of the Partnership.

         F. In no event may an Indemnitee subject any of the Partners to
personal liability by reason of the indemnification provisions set forth in this
Agreement.

         G. An Indemnitee shall not be denied indemnification in whole or in
part under this Section 7.7 because the Indemnitee had an interest in the
transaction with respect to which the indemnification applies if the transaction
was otherwise permitted by the terms of this Agreement.

         H. The provisions of this Section 7.7 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 7.7 or any provision hereof
shall be prospective only and shall not in any way affect the Partnership's
liability to any Indemnitee under this Section 7.7, as in effect immediately
prior to such amendment, modification, or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or
be asserted.

         Section 7.8 Liability of the General Partner
                     --------------------------------

         A. Notwithstanding anything to the contrary set forth in this
Agreement, the General Partner and its officers and directors shall not be
liable for monetary damages to the Partnership, any Partners or any Assignees
for losses sustained or liabilities incurred as a result of errors in judgment
or of any act or omission if the General Partner acted in good faith.

         B. The Limited Partners expressly acknowledge that, as stated in
Section 7.1.D, the General Partner is acting on behalf of the Partnership and
the shareholders of the Company collectively, that the General Partner is under
no obligation to consider the separate interests of the Limited Partners in
deciding whether to cause the Partnership to take (or decline to take) any
actions, and that the General Partner shall not be liable for monetary damages
for losses sustained, liabilities incurred, or benefits not derived by Limited
Partners in connection with such decisions, provided that the General Partner
has acted in good faith.

         C. Subject to its obligations and duties as General Partner set forth
in Section 7.1.A hereof, the General Partner may exercise any of the powers
granted to it by this Agreement and perform any of the duties imposed upon it
hereunder either directly or by or through its agents. The General Partner shall
not be responsible for any misconduct or negligence on the part of any such
agent appointed by the General Partner in good faith.

         D. Any amendment, modification or repeal of this Section 7.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the General Partner's and its officers' and directors' liability
to the Partnership and the Limited Partners under this Section 7.8 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

         Section 7.9 Other Matters Concerning the General Partner 
                     --------------------------------------------

         A. The General Partner may rely and shall be protected in acting, or
refraining from acting, upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other
paper or document believed by it in good faith to be genuine and to have been
signed or presented by the proper party or parties.

         B. The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers, architects, engineers,
environmental consultants and other consultants and advisers selected by it, and
any act taken or omitted to be taken in reliance upon the opinion of such
Persons as to matters which such General Partner reasonably believes to be
within such Person's professional or expert competence shall be conclusively
presumed to have been done or omitted in good faith and in accordance with such
opinion.

                                       31

<PAGE>



         C. The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any of its duly authorized
officers and duly appointed attorneys-in-fact. Each such attorney shall, to the
extent provided by the General Partner in the power of attorney, have full power
and authority to do and perform all and every act and duty which is permitted or
required to be done by the General Partner hereunder.

         D. Notwithstanding any other provisions of this Agreement or the Act,
any action of the General Partner on behalf of the Partnership or any decision
of the General Partner to refrain from acting on behalf of the Partnership,
undertaken in the good faith belief that such action or omission is necessary or
advisable in order (i) to protect the ability of the Company to continue to
qualify as a REIT; or (ii) to avoid the Company incurring any taxes under
Section 857 or Section 4981 of the Code, is expressly authorized under this
Agreement and is deemed approved by all of the Limited Partners.

         Section 7.10 Title to Partnership Assets
                      ---------------------------

         Title to Partnership assets, whether real, personal or mixed and
whether tangible or intangible, shall be deemed to be owned by the Partnership
as an entity, and no Partner, individually or collectively, shall have any
ownership interest in such Partnership assets or any portion thereof. Title to
any or all of the Partnership assets may be held in the name of the Partnership,
the General Partner or one or more nominees, as the General Partner may
determine, including Affiliates of the General Partner. The General Partner
hereby declares and warrants that any Partnership assets for which legal title
is held in the name of the General Partner or any nominee or Affiliate of the
General Partner shall be held by the General Partner for the use and benefit of
the Partnership in accordance with the provisions of this Agreement; provided,
however, that the General Partner shall use its best efforts to cause beneficial
and record title to such assets to be vested in the Partnership as soon as
reasonably practicable if failure to so vest such title would have a material
adverse effect on the Partnership. All Partnership assets shall be recorded as
the property of the Partnership in its books and records, irrespective of the
name in which legal title to such Partnership assets is held.

         Section 7.11 Reliance by Third Parties
                      -------------------------

         Notwithstanding anything to the contrary in this Agreement, any Person
dealing with the Partnership shall be entitled to assume that the General
Partner has full power and authority, without consent or approval of any other
Partner or Person, to encumber, sell or otherwise use in any manner any and all
assets of the Partnership and to enter into any contracts on behalf of the
Partnership, and take any and all actions on behalf of the Partnership and such
Person shall be entitled to deal with the General Partner as if the General
Partner were the Partnership's sole party in interest, both legally and
beneficially. Each Limited Partner hereby waives any and all defenses or other
remedies which may be available against such Person to contest, negate or
disaffirm any action of the General Partner in connection with any such dealing.
In no event shall any Person dealing with the General Partner or its

                                       32

<PAGE>



representatives be obligated to ascertain that the terms of this Agreement have
been complied with or to inquire into the necessity or expedience of any act or
action of the General Partner or its representatives. Each and every
certificate, document or other instrument executed on behalf of the Partnership
by the General Partner or its representatives shall be conclusive evidence in
favor of any and every Person relying thereon or claiming thereunder that (i) at
the time of the execution and delivery of such certificate, document or
instrument, this Agreement was in full force and effect; (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership; and
(iii) such certificate, document or instrument was duly executed and delivered
in accordance with the terms and provisions of this Agreement and is binding
upon the Partnership.


             ARTICLE 8 - RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

         Section 8.1 Limitation of Liability
                     -----------------------

         The Limited Partners shall have no liability under this Agreement
except as expressly provided in this Agreement, including Section 10.5 hereof,
or under the Act.

         Section 8.2 Management of Business
                     ----------------------

         No Limited Partner or Assignee (other than the General Partner, any of
its Affiliates or any officer, director, employee, agent or trustee of the
General Partner, the Partnership or any of their Affiliates, in their capacity
as such) shall take part in the operation, management or control (within the
meaning of the Act) of the Partnership's business, transact any business in the
Partnership's name or have the power to sign documents for or otherwise bind the
Partnership. The transaction of any such business by the General Partner, any of
its Affiliates or any officer, director, employee, partner, agent or trustee of
the General Partner, the Partnership or any of their Affiliates, in their
capacity as such, shall not affect, impair or eliminate the limitations on the
liability of the Limited Partners or Assignees under this Agreement.

         Section 8.3 Outside Activities of Limited Partners
                     --------------------------------------

         Subject to any agreements entered into pursuant to Section 7.6.E hereof
and any other agreements entered into by a Limited Partner or its Affiliates
with the Partnership or any of its Subsidiaries, any Limited Partner (other than
the Company) and any officer, director, employee, agent, trustee, Affiliate or
shareholder of any Limited Partner shall be entitled to and may have business
interests and engage in business activities in addition to those relating to the
Partnership, including business interests and activities that are in direct
competition with the Partnership or that are enhanced by the activities of the
Partnership. Neither the Partnership nor any Partners shall have any rights by
virtue of this Agreement in any business

                                                        33

<PAGE>



ventures of any Limited Partner or Assignee. None of the Limited Partners (other
than the Company) nor any other Person shall have any rights by virtue of this
Agreement or the Partnership relationship established hereby in any business
ventures of any other Person and such Person shall have no obligation pursuant
to this Agreement to offer any interest in any such business ventures to the
Partnership, any Limited Partner or any such other Person, even if such
opportunity is of a character which, if presented to the Partnership, any
Limited Partner or such other Person, could be taken by such Person.

         Section 8.4 Return of Capital
                     -----------------

         Except pursuant to the right of redemption set forth in Section 8.6, no
Limited Partner shall be entitled to the withdrawal or return of its Capital
Contribution, except to the extent of distributions made pursuant to this
Agreement or upon termination of the Partnership as provided herein. Except to
the extent provided by Exhibit C hereof or as otherwise expressly provided in
this Agreement, no Limited Partner or Assignee shall have priority over any
other Limited Partner or Assignee, either as to the return of Capital
Contributions or as to profits, losses or distributions.

         Section 8.5 Rights of Limited Partners Relating to the Partnership
                     ------------------------------------------------------

         A. In addition to the other rights provided by this Agreement or by the
Act, and except as limited by Section 8.5.C hereof, each Limited Partner shall
have the right, for a purpose reasonably related to such Limited Partner's
interest as a limited partner in the Partnership, upon written demand with a
statement of the purpose of such demand and at such Limited Partner's own
expense (including such copying and administrative charges as the General
Partner may establish from time to time):

                  (1)      to obtain a copy of the most recent annual and
                           quarterly reports filed with the Securities and
                           Exchange Commission by the Company pursuant to the
                           Securities Exchange Act of 1934;

                  (2)      to obtain a copy of the Partnership's federal, state
                           and local income tax returns for each Partnership
                           Year;

                  (3)      to obtain a current list of the name and last known
                           business, residence or mailing address of each
                           Partner;

                  (4)      to obtain a copy of this Agreement and the
                           Certificate of Limited Partnership and all amendments
                           thereto, together with executed copies of all powers
                           of attorney pursuant to which this Agreement, the
                           Certificate of Limited Partnership and all amendments
                           thereto have been executed; and


                                       34

<PAGE>



                  (5)      to obtain true and full information regarding the
                           amount of cash and a description and statement of any
                           other property or services contributed by each
                           Partner and which each Partner has agreed to
                           contribute in the future, and the date on which each
                           became a Partner.

         B. The Partnership shall notify each Limited Partner, upon request, of
the then current Conversion Factor and the REIT Shares Amount per Partnership
Unit and, with reasonable detail, how the same was determined.

         C. Notwithstanding any other provision of this Section 8.5, the General
Partner may keep confidential from the Limited Partners, for such period of time
as the General Partner determines in its sole and absolute discretion to be
reasonable, any information that (i) the General Partner reasonably believes to
be in the nature of trade secrets or other information, the disclosure of which
the General Partner in good faith believes is not in the best interests of the
Partnership or could damage the Partnership or its business; or (ii) the
Partnership is required by law or by agreements with an unaffiliated third party
to keep confidential.

         Section 8.6 Redemption Right
                     ----------------

         A. Subject to Sections 8.6.B and 8.6.C hereof, on or after that date
which is twelve (12) months after the Effective Date, each Limited Partner
(other than the Company) shall have the right (the "Redemption Right") to
require the Partnership to redeem on a Specified Redemption Date all or a
portion of the Partnership Units (other than the Convertible Unit) held by such
Limited Partner at a redemption price per Unit equal to and in the form of the
Cash Amount to be paid by the Partnership. The Redemption Right shall be
exercised pursuant to a Notice of Redemption delivered to the Partnership (with
a copy to the Company) by the Limited Partner who is exercising the redemption
right (the "Redeeming Partner"); provided, however, that the Partnership shall
not be obligated to satisfy such Redemption Right if the Company elects to
purchase the Partnership Units subject to the Notice of Redemption pursuant to
Section 8.6.B. A Limited Partner may not exercise the Redemption Right for less
than one thousand (1,000) Partnership Units or, if such Limited Partner holds
less than one thousand (1,000) Partnership Units, all of the Partnership Units
held by such Partner. The Redeeming Partner shall have no right, with respect to
any Partnership Units so redeemed, to receive any distributions paid on or after
the Specified Redemption Date. The Assignee of any Limited Partner may exercise
the rights of such Limited Partner pursuant to this Section 8.6, and such
Limited Partner shall be deemed to have assigned such rights to such Assignee
and shall be bound by the exercise of such rights by such Assignee. In
connection with any exercise of such rights by an Assignee on behalf of a
Limited Partner, the Cash Amount shall be paid by the Partnership directly to
such Assignee and not to such Limited Partner.

         B. Notwithstanding the provisions of Section 8.6.A, a Limited Partner
that exercises the Redemption Right shall be deemed to have offered to sell the
Partnership Units

                                       35

<PAGE>



described in the Notice of Redemption to the Company, and the Company may, in
its discretion elect to purchase directly and acquire such Partnership Units by
paying to the Redeeming Partner either the Cash Amount or the REIT Shares
Amount, on the Specified Redemption Date, whereupon the Company shall acquire
the Partnership Units offered for redemption by the Redeeming Partner and shall
be treated for all purposes of this Agreement as the owner of such Partnership
Units; provided, however, that the election by the Company to purchase directly
and acquire an Incentive Unit by paying the Cash Amount or the REIT Shares
Amount pursuant to this Section 8.6B shall first be approved by the Independent
Directors of the Company. If the Company shall elect to exercise its right to
purchase Partnership Units under this Section 8.6.B with respect to a Notice of
Redemption, it shall so notify the Redeeming Partner within five (5) Business
Days after the receipt by it of such Notice of Redemption. Unless the Company
(as directed by the Partnership in its sole and absolute discretion) shall
exercise its right to purchase Partnership Units from the Redeeming Partner
pursuant to this Section 8.6.B, the Company shall not have any obligation to the
Redeeming Partner or the Partnership with respect to the Redeeming Partner's
exercise of the Redemption Right. In the event the Company shall exercise its
right to purchase Partnership Units with respect to the exercise of a Redemption
Right in the manner described in the first sentence of this Section 8.6.B, the
Partnership shall have no obligation to pay any amount to the Redeeming Partner
with respect to such Redeeming Partner's exercise of such Redemption Right, and
each of the Redeeming Partner, the Partnership, and the Company shall treat the
transaction between the Company and the Redeeming Partner as a sale of the
Redeeming Partner's Partnership Units to the Company. Each Redeeming Partner
agrees to execute such documents as the Company may reasonably require in
connection with the issuance of REIT Shares upon exercise of the Redemption
Right.

         C. Notwithstanding the provisions of Section 8.6.A and Section 8.6.B, a
Partner shall not be entitled to exercise the Redemption Right pursuant to
Section 8.6.A if the delivery of REIT Shares to such Partner on the Specified
Redemption Date by the Company pursuant to Section 8.6.B (regardless of whether
or not the Company would in fact exercise its rights under Section 8.6.B) would
be prohibited under the Certificate of Incorporation of the Company.

         D. In the event that the Partnership issues additional Partnership
Interests pursuant to Section 4.2.A hereof, the General Partner shall make such
revisions to this Section 8.6 as it determines are necessary to reflect the
issuance of such additional Partnership Interests.


               ARTICLE 9 - BOOKS, RECORDS, ACCOUNTING AND REPORTS

         Section 9.1 Records and Accounting
                     ----------------------

         The General Partner shall keep or cause to be kept at the principal
office of the Partnership those records and documents required to be maintained
by the Act and other books

                                       36

and records deemed by the General Partner to be appropriate with respect to the
Partnership's business, including, without limitation, all books and records
necessary to provide to the Limited Partners any information, lists and copies
of documents required to be provided pursuant to Section 9.3 hereof. Any records
maintained by or on behalf of the Partnership in the regular course of its
business may be kept on, or be in the form of, punch cards, magnetic tape,
photographs, micrographics or any other information storage device, provided
that the records so maintained are convertible into clearly legible written form
within a reasonable period of time. The books of the Partnership shall be
maintained, for financial and tax reporting purposes, on an accrual basis in
accordance with generally accepted accounting principles, or such other basis as
the General Partner determines to be necessary or appropriate.

         Section 9.2 Fiscal Year
                     -----------

         The fiscal year of the Partnership shall be the calendar year.

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

any tax election it makes (including, without limitation, the election under
Section 754 of the Code) upon the General Partner's determination, in its sole
and absolute discretion, that such revocation is in the best interests of the
Partners.

         Section 10.3 Tax Matters Partner
                      -------------------

         A. The General Partner shall be the "tax matters partner" of the
Partnership for federal income tax purposes. Pursuant to Section 6230(e) of the
Code, upon receipt of notice from the IRS of the beginning of an administrative
proceeding with respect to the Partnership, the tax matters partner shall
furnish the IRS with the name, address, taxpayer identification number, and
profit interest of each of the Limited Partners and the Assignees; provided,
however, that such information is provided to the Partnership by the Limited
Partners and the Assignees.

         B. The tax matters partner is authorized, but not required:

                  (1)      to enter into any settlement with the IRS with
                           respect to any administrative or judicial proceedings
                           for the adjustment of Partnership items required to
                           be taken into account by a Partner for income tax
                           purposes (such administrative proceedings being
                           referred to as a "tax audit" and such judicial
                           proceedings being referred to as "judicial review"),
                           and in the settlement agreement the tax matters
                           partner may expressly state that such agreement shall
                           bind all Partners, except that such settlement
                           agreement shall not bind any Partner (i) who (within
                           the time prescribed pursuant to the Code and
                           Regulations) files a statement with the IRS providing
                           that the tax matters partner shall not have the
                           authority to enter into a settlement agreement on
                           behalf of such Partner; or (ii) who is a "notice
                           partner" (as defined in Section 6231(a)(8) of the

                                       38

<PAGE>



                           Code) or a member of a "notice group" (as defined in
                           Section 6223(b)(2) of the Code);

                  (2)      in the event that a notice of a final administrative
                           adjustment at the Partnership level of any item
                           required to be taken into account by a Partner for
                           tax purposes (a "final adjustment") is mailed to the
                           tax matters partner, to seek judicial review of such
                           final adjustment, including the filing of a petition
                           for readjustment with the Tax Court or the filing of
                           a complaint for refund with the United States Claims
                           Court or the District Court of the United States for
                           the district in which the Partnership's principal
                           place of business is located;

                  (3)      to intervene in any action brought by any other
                           Partner for judicial review of a final adjustment;

                  (4)      to file a request for an administrative adjustment
                           with the IRS and, if any part of such request is not
                           allowed by the IRS, to file an appropriate pleading
                           (petition or complaint) for judicial review with
                           respect to such request;

                  (5)      to enter into an agreement with the IRS to extend the
                           period for assessing any tax which is attributable to
                           any item required to be taken account of by a Partner
                           for tax purposes, or an item affected by such item;
                           and

                  (6)      to take any other action on behalf of the Partners or
                           the Partnership in connection with any tax audit or
                           judicial review proceeding to the extent permitted by
                           applicable law or regulations.

         The taking of any action and the incurring of any expense by the tax
matters partner in connection with any such proceeding, except to the extent
required by law, is a matter in the sole and absolute discretion of the tax
matters partner and the provisions relating to indemnification of the General
Partner set forth in Section 7.7 of this Agreement shall be fully applicable to
the tax matters partner in its capacity as such.

         C. The tax matters partner shall receive no compensation for its
services. All third party costs and expenses incurred by the tax matters partner
in performing its duties as such (including legal and accounting fees and
expenses) shall be borne by the Partnership. Nothing herein shall be construed
to restrict the Partnership from engaging an accounting firm to assist the tax
matters partner in discharging its duties hereunder, so long as the compensation
paid by the Partnership for such services is reasonable.

         Section 10.4 Organizational Expenses
                      -----------------------

         The Partnership shall elect to deduct expenses, if any, incurred by it
in organizing the Partnership ratably over a sixty (60) month period as provided
in Section 709 of the Code.

         Section 10.5 Withholding
                      -----------

         Each Limited Partner hereby authorizes the Partnership to withhold
from, or pay on behalf of or with respect to, such Limited Partner any amount of
federal, state, local, or foreign taxes that the General Partner determines that
the Partnership is required to withhold or pay with respect to any amount
distributable or allocable to such Limited Partner pursuant to this Agreement,
including, without limitation, any taxes required to be withheld or paid by the
Partnership pursuant to Sections 1441, 1442, 1445, or 1446 of the Code. Any
amount paid on behalf of or with respect to a Limited Partner shall constitute a
loan by the Partnership to such Limited Partner, which loan shall be repaid by
such Limited Partner within fifteen (15) days after notice from the General
Partner that such payment must be made unless (i) the Partnership withholds such
payment from a distribution which would otherwise be made to the Limited
Partner; or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the available funds of the
Partnership which would, but for such payment, be distributed to the Limited
Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii)
shall be treated as having been distributed to such Limited Partner. Each
Limited Partner hereby unconditionally and irrevocably grants to the Partnership
a security interest in such Limited Partner's Partnership Interest to secure
such Limited Partner's obligation to pay to the Partnership any amounts required
to be paid pursuant to this Section 10.5. In the event that a Limited Partner
fails to pay any amounts owed to the Partnership pursuant to this Section 10.5
when due, the General Partner may, in its sole and absolute discretion, elect to
make the payment to the Partnership on behalf of such defaulting Limited
Partner, and in such event shall be deemed to have loaned such amount to such
defaulting Limited Partner and shall succeed to all rights and remedies of the
Partnership as against such defaulting Limited Partner. Without limitation, in
such event the General Partner shall have the right to receive distributions
that would otherwise be distributable to such defaulting Limited Partner until
such time as such loan, together with all interest thereon, has been paid in
full, and any such distributions so received by the General Partner shall be
treated as having been distributed to the defaulting Limited Partner and
immediately paid by the defaulting Limited Partner to the General Partner in
repayment of such loan. Any amounts payable by a Limited Partner hereunder shall
bear interest at the lesser of (A) the base rate on corporate loans at large
United States money center commercial banks, as published from time to time in
The Wall Street Journal, plus four (4) percentage points, or (B) the maximum
lawful rate of interest on such obligation, such interest to accrue from the
date such amount is due (i.e., fifteen (15) days after demand) until such amount
is paid in full. Each Limited Partner shall take such actions as the Partnership
or the General Partner shall request in order to perfect or enforce the security
interest created hereunder.

Partner or any acquisition of Partnership Units from a Limited Partner by the
Company pursuant to Section 8.6. No part of the interest of a Limited Partner
shall be subject to the claims of any creditor, any spouse for alimony or
support, or to legal process, and may not be voluntarily or involuntarily
alienated or encumbered except as may be specifically provided for in this
Agreement or consented to by the General Partner.

         B. No Partnership Interest shall be transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article 11.

                      Limited Partner Interest; Extraordinary Transactions
                      ----------------------------------------------------

         A. The Company may not transfer any of its General Partner Interest or
withdraw as General Partner, or transfer any of its Limited Partner Interest, or
engage in an Extraordinary Transaction, except, in any such case, (i) if such

         B. The General Partner is permitted to engage in the following
Extraordinary Transactions without the approval or vote of the Limited Partners
except as provided in Section 11.2(C):

                  (i)      an Extraordinary Transaction in connection with which
                           all Limited Partners either will receive, or will
                           have the right to elect to receive, for

                                       41

                           each Partnership Unit an amount of cash, securities,
                           or other property equal to the product of the REIT
                           Shares Amount and the greatest amount of cash,
                           securities or other property paid to a holder of one

                           pursuant to the terms of the Extraordinary
                           Transaction; provided that, if, in connection with
                           the Extraordinary Transaction, a purchase, tender or
                           exchange offer shall have been made to and accepted
                           by the holders of the outstanding REIT Shares, each
                           holder of Partnership Units shall receive, or shall
                           have the right to elect to receive, the greatest
                           amount of cash, securities, or other property which
                           such holder would have received had it exercised its
                           right to Redemption (as set forth in Section 8.6A)
                           and received REIT Shares in exchange for its
                           Partnership Units immediately prior to the expiration
                           of such purchase, tender or exchange offer and had
                           thereupon accepted such purchase, tender or exchange
                           offer and then such Extraordinary Transaction shall
                           have been consummated; and

                  (ii)     a merger, or other combination of assets, with
                           another entity if: (w) immediately after such
                           Extraordinary Transaction, substantially all of the
                           assets directly or indirectly owned by the surviving
                           entity, other than Partnership Units held by such
                           General Partner, are owned directly or indirectly by
                           the Partnership or another limited partnership or
                           limited liability company which is the survivor of a
                           merger, consolidation or combination of assets with
                           the Partnership (in each case, the "Surviving
                           Partnership"); (x) the Limited Partners own a
                           percentage interest of the Surviving Partnership
                           based on the relative fair market value of the net
                           assets of the Partnership (as determined pursuant to
                           Section 11.2.E) and the other net assets of the
                           Surviving Partnership (as determined pursuant to
                           Section 11.2.E) immediately prior to the consummation
                           of such transaction; (y) the rights, preferences and
                           privileges of the Limited Partners in the Surviving
                           Partnership are at least as favorable as those in
                           effect immediately prior to the consummation of such
                           transaction and as those applicable to any other
                           limited partners or non-managing members of the
                           Surviving Partnership; and (z) such rights of the
                           Limited Partners include the right to exchange their
                           interests in the Surviving Partnership for at least
                           one of: (a) the consideration available to such
                           Limited Partners pursuant to Section 11.2.B(i) or (b)
                           if the ultimate controlling person of the Surviving
                           Partnership has publicly traded common equity
                           securities, such common equity securities, with an
                           exchange ratio based on the relative fair market
                           value of such securities (as determined pursuant to
                           Section 11.2.E) and the REIT Shares.

                  (iii)    Notwithstanding the foregoing, in the case of any
                           Extraordinary Transaction described in clauses (i)
                           and (ii) of Section 11.2B, the amount

<PAGE>



                           of consideration that each holder of Incentive Units
                           shall be entitled to receive with respect to the
                           Incentive Units shall be limited to consideration
                           with a value no greater than the value of the amount
                           of cash, securities or other property which such
                           holder would have received had it exercised its right
                           to Redemption (as set forth in Section 8.6A) and
                           received the Cash Amount in exchange for its
                           Partnership Units immediately prior to the expiration
                           of the consummation of the Extraordinary Transaction
                           or expiration of any purchase, tender or exchange
                           offer, as the case may be, and then such
                           Extraordinary Transaction shall have been
                           consummated.

         C. The General Partner shall not consummate any Extraordinary
Transaction in connection with which it conducted a vote of its stockholders (a
"Stockholder Vote") unless the General Partner also conducts a vote of the
Partners of the Partnership (the "Partnership Vote") in which (i) the General
Partner provides the Partners with advance notice equal in time to the advance
notice given in the case of the Stockholder Vote, (ii) in connection with such
advance notice the General Partner provides the Partners with written materials
describing the proposed Extraordinary Transaction as well as the tax effect of
the consummation thereof on the Limited Partners, (iii) in such vote of the
Partners, the General Partner votes all Partnership Interests (General and
Limited) held by it in proportion to the manner in which all outstanding shares
of capital stock of the General Partner were voted at the Stockholder Meeting
(such votes to be "For," "Against," "Abstain" and "Not Present"), and (iv) the
total votes of the General and Limited Partners voted "For," "Against,"
"Abstain" and "Not Present" would be sufficient (measured in percentage terms),
if such vote were a vote by the Company of its stockholders, to approve the
Extraordinary Transaction. For purposes of the Partnership Vote, each holder of
a Partnership Interest shall be entitled to a number of votes equal to the total
votes such holder would have been entitled to at the Stockholder Meeting had
such holder presented its Partnership Interest for redemption and such
Partnership Interest had been acquired by the Company for the REIT Shares Amount
of REIT Shares prior to the record date therefor.

         D. Without in any way limiting the exculpation from liability set forth
in Section 7.1.D and 7.8.B, in connection with any transaction permitted by
Section 11.2.B or Section 11.2.C hereof, the General Partner shall use its
commercially reasonable efforts to structure such Extraordinary Transaction to
avoid causing the Limited Partners to recognize gain for federal income tax
purposes by virtue of the occurrence of or their participation in such
Extraordinary Transaction.

         E. In connection with any transaction permitted by Section 11.2.B or
11.2.C, the relative fair market values shall be reasonably determined by the
General Partner as of the time of such transaction and, to the extent
applicable, shall be no less favorable to the Limited Partners than the relative
values reflected in the terms of such transaction.

         Section 11.3 Limited Partners' Rights to Transfer
                      ------------------------------------

         A. Subject to the provisions of Sections 11.3.C, 11.3.D, 11.3.E, and
11.4, a Limited Partner (other than the Company) may, after the expiration of
one year from the Effective Date, transfer, with or without the consent of the
General Partner, all or any portion of its Partnership Interest, or any of such
Limited Partner's economic rights as a Limited Partner.

         B. If a Limited Partner is subject to Incapacity, the executor,
administrator, trustee, committee, guardian, conservator or receiver of such
Limited Partner's estate shall have all of the rights of a Limited Partner, but
not more rights than those enjoyed by other Limited Partners, for the purpose of
settling or managing the estate and such power as the Incapacitated Limited
Partner possessed to transfer all or any part of his or its interest in the
Partnership. The Incapacity of a Limited Partner, in and of itself, shall not
dissolve or terminate the Partnership.

         C. The General Partner may prohibit any transfer by a Limited Partner
of its Partnership Units if, in the opinion of legal counsel to the Partnership,
such transfer would require filing of a registration statement under the
Securities Act of 1933 or would otherwise violate any federal or state
securities laws or regulations applicable to the Partnership or the Partnership
Units.

         D. No transfer by a Limited Partner of its Partnership Units may be
made to any Person if (i) in the opinion of legal counsel for the Partnership,
it would result in the Partnership being treated as an association taxable as a
corporation; (ii) it is made within one year after the consummation of the
initial public offering of the Company; (iii) such transfer is effectuated
through an "established securities market" or a "secondary market (or the
substantial equivalent thereof)" within the meaning of Section 7704 of the Code;
(iv) such transfer would cause the Partnership to become, with respect to any
employee benefit plan subject to Title I of ERISA, a "party-in-interest" (as
defined in Section 3(14) of ERISA) or a "disqualified person" (as defined in
Section 4975(c) of the Code); (v) such transfer would, in the opinion of legal
counsel for the Partnership, cause any portion of the assets of the Partnership
to constitute assets of any employee benefit plan pursuant to Department of
Labor Regulations Section 2510.2-101; or (vi) such transfer would subject the
Partnership to be regulated under the Investment Company Act of 1940, the
Investment Advisors Act of 1940 or the Employee Retirement Income Security Act
of 1974, each as amended.

         E. No transfer of any Partnership Units may be made to a lender to the
Partnership or any Person who is related (within the meaning of Section
1.752-4(b) of the Regulations) to any lender to the Partnership whose loan
constitutes a Nonrecourse Liability, without the consent of the General Partner,
which consent shall not be unreasonably withheld.

         Section 11.4 Substituted Limited Partners
                      ----------------------------

         A. No Limited Partner shall have the right to substitute a transferee
as a Limited Partner in his place. The General Partner shall, however, have the
right to consent to the admission of a transferee of the interest of a Limited
Partner pursuant to this Section 11.4 as a Substituted Limited Partner, which
consent may be given or withheld by the General Partner in its sole and absolute
discretion. The General Partner's failure or refusal to permit a transferee of
any such interests to become a Substituted Limited Partner shall not give rise
to any cause of action against the Partnership or any Partner.

         B. A transferee who has been admitted as a Substituted Limited Partner
in accordance with this Article 11 shall have all the rights and powers and be
subject to all the restrictions and liabilities of a Limited Partner under this
Agreement.

         C. Upon the admission of a Substituted Limited Partner, the General
Partner shall amend Exhibit A to reflect the name, address, number of
Partnership Units, and Percentage Interest of such Substituted Limited Partner
and to eliminate or adjust, if necessary, the name, address and interest of the
predecessor of such Substituted Limited Partner.

         Section 11.5 Assignees
                      ---------

         If the General Partner, in its sole and absolute discretion, does not
consent to the admission of any permitted transferee as a Substituted Limited
Partner, as described in Section 11.4, such transferee shall be considered an
Assignee for purposes of this Agreement. An Assignee shall be deemed to have had
assigned to it, and shall be entitled to receive distributions from the
Partnership and the share of Net Income, Net Losses, and any other items, gain,
loss deduction and credit of the Partnership attributable to the Partnership
Units assigned to such transferee, but except as otherwise provided in Section
8.6.A hereof shall not be deemed to be a holder of Partnership Units for any
other purpose under this Agreement, and shall not be entitled to vote such
Partnership Units in any matter presented to the Limited Partners for a vote
(such Partnership Units being deemed to have been voted on such matter in the
same proportion as all other Partnership Units held by Limited Partners are
voted). In the event any such transferee desires to make a further assignment of
any such Partnership Units, such transferee shall be subject to all of the
provisions of this Article 11 to the same extent and in the same manner as any
Limited Partner desiring to make an assignment of Partnership Units.

         Section 11.6 General Provisions
                      ------------------

         A. No Limited Partner may withdraw from the Partnership other than as a
result of a permitted transfer of all of such Limited Partner's Partnership
Units in accordance with this Article 11 or pursuant to redemption or transfer
of all of its Partnership Units under Section 8.6.

                                       45

<PAGE>



         B. Any Limited Partner who shall transfer all of its Partnership Units
in a transfer permitted pursuant to this Article 11 shall cease to be a Limited
Partner upon the admission of all Assignees of such Partnership Units as
Substitute Limited Partners. Similarly, any Limited Partner who shall transfer
all of its Partnership Units pursuant to a redemption of all of its Partnership
Units under Section 8.6 shall cease to be a Limited Partner.

         C. Transfers pursuant to this Article 11 may only be made on the first
day of a fiscal quarter of the Partnership, unless the General Partner otherwise
agrees.

         D. If any Partnership Interest is transferred or assigned during any
quarterly segment of the Partnership's fiscal year in compliance with the
provisions of this Article 11 or redeemed or transferred pursuant to Section 8.6
on any day other than the first day of a Partnership Year, then Net Income, Net
Losses, each item thereof and all other items attributable to such interest for
such Partnership Year shall be divided and allocated between the transferor
Partner and the transferee Partner by taking into account their varying
interests during the Partnership Year in accordance with Section 706(d) of the
Code. The General Partner may adopt such conventions relating to allocations in
connection with transfers, assignments or redemptions as it determines are
necessary or appropriate. All distributions of Available Cash attributable to
such Partnership Unit with respect to which the Partnership Record Date is
before the date of such transfer, assignment, or redemption shall be made to the
transferor Partner or the Redeeming Partner, as the case may be, and in the case
of a transfer or assignment other than a redemption, all distributions of
Available Cash thereafter attributable to such Partnership Unit shall be made to
the transferee Partner.

         Section 12.1 Admission of Successor General Partner
                      --------------------------------------

         A successor to all of the General Partner Interest pursuant to Section
11.2 hereof who is proposed to be admitted as a successor General Partner shall
be admitted to the Partnership as the General Partner, effective upon such
transfer. Any such transferee shall carry on the business of the Partnership
without dissolution. In each case, the admission shall be subject to the
successor General Partner executing and delivering to the Partnership an
acceptance of all of the terms and conditions of this Agreement and such other
documents or instruments as may be required to effect the admission. In the case
of such admission on any day other than the first day of a Partnership Year, all
items attributable to the General Partner Interest for such Partnership Year
shall be allocated between the transferring General Partner and such successor
as provided in Section 11.6.D hereof.

         Section 12.2 Admission of Additional Limited Partners
                      ----------------------------------------

         A. After the admission to the Partnership of the initial Limited
Partners on the date hereof, a Person who makes a Capital Contribution to the
Partnership in accordance with this Agreement shall be admitted to the
Partnership as an Additional Limited Partner only upon furnishing to the General
Partner (i) evidence of acceptance in form satisfactory to the General Partner
of all of the terms and conditions of this Agreement, including, without
limitation, the power of attorney granted in Section 2.4 hereof and (ii) such
other documents or instruments as may be required in the discretion of the
General Partner in order to effect such Person's admission as an Additional
Limited Partner.

         B. Notwithstanding anything to the contrary in this Section 12.2, no
Person shall be admitted as an Additional Limited Partner without the consent of
the General Partner, which consent may be given or withheld in the General
Partner's sole and absolute discretion. The admission of any Person as an
Additional Limited Partner shall become effective on the date upon which the
name of such Person is recorded on the books and records of the Partnership,
following the consent of the General Partner to such admission.

         C. If any Additional Limited Partner is admitted to the Partnership on
any day other than the first day of a Partnership Year, then Net Income, Net
Losses, each item thereof and all other items allocable among Partners and
Assignees for such Partnership Year shall be allocated among such Additional
Limited Partner and all other Partners and Assignees by taking into account
their varying interests during the Partnership Year in accordance with Section
706(d) of the Code, using any convention permitted by law and selected by the
General Partner. All distributions of Available Cash with respect to which the
Partnership Record Date is before the date of such admission shall be made
solely to Partners and Assignees, other than the Additional Limited Partner, and
all distributions of Available Cash thereafter shall be made to all of the
Partners and Assignees, including such Additional Limited Partner.

                      -----------

         For the admission to the Partnership of any Partner, the General
Partner shall take all steps necessary and appropriate under the Act to amend
the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
of Limited Partnership and may for this purpose exercise the power of attorney
granted pursuant to Section 2.4 hereof.

         Section 13.1 Dissolution
                      -----------

         The Partnership shall not be dissolved by the admission of Substituted
Limited Partners or Additional Limited Partners or by the admission of a
successor General Partner in accordance with the terms of this Agreement. Upon
the withdrawal of the General Partner, any successor General Partner shall
continue the business of the Partnership. The Partnership shall dissolve, and
its affairs shall be wound up, only upon the first to occur of any of the
following ("Liquidating Events"):

         A. an event of withdrawal of the General Partner, as defined in the Act
(other than an event of bankruptcy), unless, within ninety (90) days after such
event of withdrawal a majority in interest of the remaining Partners agree in
writing to continue the business of the Partnership and to the appointment,
effective as of the date of withdrawal, of a successor General Partner;

         B. from and after the date of this Agreement through December 31, 2055,

Consent of Partners holding eighty-five percent (85%) of the Percentage
Interests of the Limited Partners (including Limited Partner Interests held by

         C. on or after January 1, 2056, an election to dissolve the Partnership
made by the General Partner, in its sole and absolute discretion;

         D. entry of a decree of judicial dissolution of the Partnership
pursuant to the provisions of the Act;

         E. the sale of all or substantially all of the assets and properties of
the Partnership; or

         F. a final and non-appealable judgment is entered by a court of
competent jurisdiction ruling that the General Partner is bankrupt or insolvent,
or a final and non-appealable order for relief is entered by a court with
appropriate jurisdiction against the General Partner, in each case under any
federal or state bankruptcy or insolvency laws as now or hereafter in effect,
unless prior to the entry of such order or judgment all of the remaining
Partners agree in writing to continue the business of the Partnership and to the
appointment, effective as of a date prior to the date of such order or judgment,
of a substitute General Partner.

         Section 13.2 Winding Up
                      ----------

         A. Upon the occurrence of a Liquidating Event, the Partnership shall
continue solely for the purposes of winding up its affairs in an orderly manner,
liquidating its assets, and satisfying the claims of its creditors and Partners.
No Partner shall take any action that is inconsistent with, or not necessary to
or appropriate for, the winding up of the Partnership's business and affairs.
The General Partner, or, in the event there is no remaining General Partner, any
Person elected by a majority in interest of the Limited Partners (the General
Partner or such other Person being referred to herein as the "Liquidator"),
shall be responsible for overseeing the winding up and dissolution of the
Partnership and shall take full account of the Partnership's liabilities and
property and the Partnership property shall be liquidated as promptly as is
consistent with obtaining the fair value thereof, and the proceeds therefrom
(which may, to the extent determined by the General Partner, include shares of
common stock in the Company) shall be applied and distributed in the following
order:

                  (1)      First, to the payment and discharge of all of the
                           Partnership's debts and liabilities to creditors
                           other than the Partners;

                  (2)      Second, to the payment and discharge of all of the
                           Partnership's debts and liabilities to the General
                           Partner;

                  (3)      Third, to the payment and discharge of all of the
                           Partnership's debts and liabilities to the other
                           Partners; and

                  (4)      The balance, if any, to the General Partner and
                           Limited Partners in accordance with Section 5.3.

The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13.

         B. Notwithstanding the provisions of Section 13.2.A hereof which
require liquidation of the assets of the Partnership, but subject to the order
of priorities set forth therein, if prior to or upon dissolution of the
Partnership the Liquidator determines that an immediate sale of part or all of
the Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership (including to those Partners as creditors) and/or
distribute to the Partners, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 13.2.A hereof, undivided interests in
such Partnership assets as the Liquidator deems not suitable for liquidation.
Any such distributions in kind shall be made only if, in the good faith judgment
of the Liquidator, such distributions in kind are in the best interest of the
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of

                                       49

<PAGE>



such properties at such time. The Liquidator shall determine the fair market
value of any property distributed in kind using such reasonable method of
valuation as it may adopt.

         C. In the discretion of the Liquidator, a pro rata portion of the
distributions that would otherwise be made to the General Partner and Limited
Partners pursuant to this Article 13 may be:

                  (1)      distributed to a trust established for the benefit of
                           the General Partner and Limited Partners for the
                           purposes of liquidating Partnership assets,
                           collecting amounts owed to the Partnership, and
                           paying any contingent or unforeseen liabilities or
                           obligations of the Partnership or the General Partner
                           arising out of or in connection with the Partnership.
                           The assets of any such trust shall be distributed to
                           the General Partner and Limited Partners from time to
                           time, in the reasonable discretion of the Liquidator,
                           in the same proportions as the amount distributed to
                           such trust by the Partnership would otherwise have
                           been distributed to the General Partner and Limited
                           Partners pursuant to this Agreement; or

                  (2)      withheld or escrowed to provide a reasonable reserve
                           for Partnership liabilities (contingent or otherwise)
                           and to reflect the unrealized portion of any
                           installment obligations owed to the Partnership,
                           provided that such withheld or escrowed amounts shall
                           be distributed to the General Partner and Limited
                           Partners in the manner and order of priority set
                           forth in Section 13.2.A as soon as practicable.

         Section 13.3 Rights of Limited Partners
                      --------------------------

         Except as otherwise provided in this Agreement, each Limited Partner
shall look solely to the assets of the Partnership for the return of its Capital
Contributions and shall have no right or power to demand or receive property
other than cash from the Partnership. Except as otherwise provided in this
Agreement, no Limited Partner shall have priority over any other Partner as to
the return of its Capital Contributions, distributions, or allocations.

         Section 13.4 Notice of Dissolution
                      ---------------------

         In the event a Liquidating Event occurs or an event occurs that would,
but for the provisions of an election or objection by one or more Partners
pursuant to Section 13.1, result in a dissolution of the Partnership, the
General Partner shall, within thirty (30) days thereafter, provide written
notice thereof to each of the Partners.

         A reasonable time shall be allowed for the orderly winding-up of the
business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2 hereof, in order to minimize any losses otherwise
attendant upon such winding-up, and the provisions of this Agreement shall
remain in effect between the Partners during the period of liquidation.

         Section 13.7 Waiver of Partition
                      -------------------

         Each Partner hereby waives any right to partition of the Partnership
property.


            ARTICLE 14 - AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS

         Section 14.1 Amendments
                      ----------

         A. Amendments to this Agreement may be proposed by the General Partner
or by any Limited Partners (other than the Company) holding twenty percent (20%)
or more of the Partnership Interests. Following such proposal, the General
Partner shall submit any proposed amendment to the Limited Partners. The General
Partner shall seek the written vote of the Partners on the proposed amendment or
shall call a meeting to vote thereon and to transact any other business that it
may deem appropriate. For purposes of obtaining a written vote, the General
Partner may require a response within a reasonable specified time, but not less
than fifteen (15) days, and failure to respond in such time period shall
constitute a vote which is consistent with the General Partner's recommendation
with respect to the proposal. Except as provided in Section 13.1.B, 14.1.B,
14.1.C or 14.1.D, a proposed amendment shall be adopted and be effective as an
amendment hereto if it is approved by the General Partner and it receives the
Consent of Partners holding a majority of the Percentage Interests of the
Limited Partners (including Limited Partner Interests held by the Company);
provided, that, an action shall become effective at such time as the requisite
consents are received even if prior to such specified time.


                                       51

<PAGE>



         B. Notwithstanding Section 14.1.A, the General Partner shall have the
power, without the consent of the Limited Partners, to amend this Agreement as
may be required to facilitate or implement any of the following purposes:

                  (1)      to add to the obligations of the General Partner or
                           surrender any right or power granted to the General
                           Partner or any Affiliate of the General Partner for
                           the benefit of the Limited Partners;

                  (2)      to reflect the admission, substitution, termination,
                           or withdrawal of Partners in accordance with this
                           Agreement;

                  (3)      to set forth and reflect in the Agreement the
                           designations, rights, powers, duties, and preferences
                           of the holders of any additional Partnership
                           Interests issued pursuant to Section 4.2.A hereof;

                  (4)      to reflect a change that is of an inconsequential
                           nature and does not adversely affect the Limited
                           Partners in any material respect, or to cure any
                           ambiguity, correct or supplement any provision in
                           this Agreement not inconsistent with law or with
                           other provisions, or make other changes with respect
                           to matters arising under this Agreement that will not
                           be inconsistent with law or with the provisions of
                           this Agreement; and

                  (5)      to satisfy any requirements, conditions, or
                           guidelines contained in any order, directive,
                           opinion, ruling or regulation of a federal or state
                           agency or contained in federal or state law.

The General Partner shall provide notice to the Limited Partners when any action
under this Section 14.1.B is taken.

         C. Notwithstanding Section 14.1.A and 14.1.B hereof, this Agreement
shall not be amended without the Consent of each Partner adversely affected if
such amendment would (i) convert a Limited Partner's interest in the Partnership
into a General Partner Interest; (ii) modify the limited liability of a Limited

         D. Notwithstanding Section 14.1.A or Section 14.1.B hereof, the General
Partner shall not (except in connection with amendments made to reflect the
issuance of additional Partnership Interests and the relative rights, powers and
duties incident thereto) amend Sections 4.2.A, 7.5, 7.6, 11.2 or 14.2 without
the Consent of Limited Partners holding a majority of the Percentage Interests
of the Limited Partners, excluding Limited Partner Interests held by the General
Partner or its Affiliates.

         Section 14.2 Meetings of the Partners
                      ------------------------

         A. Meetings of the Partners may be called by the General Partner and
shall be called upon the receipt by the General Partner of a written request by
Limited Partners (other than the Company) holding twenty percent (20%) or more
of the Partnership Interests. The request shall state the nature of the business
to be transacted. Notice of any such meeting shall be given to all Partners not
less than seven (7) days nor more than thirty (30) days prior to the date of
such meeting. Partners may vote in person or by proxy at such meeting. Whenever
the vote or Consent of the Partners is permitted or required under this
Agreement, such vote or Consent may be given at a meeting of the Partners or may
be given in accordance with the procedure prescribed in Section 14.1.A hereof.
Except as otherwise expressly provided in this Agreement, the Consent of holders
of a majority of the Percentage Interests held by Limited Partners (including
Limited Partnership Interests held by the Company) shall control.

         B. Any action required or permitted to be taken at a meeting of the
Partners may be taken without a meeting if a written consent setting forth the
action so taken is signed by a majority of the Percentage Interests of the
Partners (or such other percentage as is expressly required by this Agreement).
Such consent may be in one instrument or in several instruments, and shall have
the same force and effect as a vote of a majority of the Percentage Interests of
the Partners (or such other percentage as is expressly required by this
Agreement). Such consent shall be filed with the General Partner. An action so
taken shall be deemed to have been taken at a meeting held on the effective date
so certified.

         C. Each Limited Partner may authorize any Person or Persons to act for
him by proxy on all matters in which a Limited Partner is entitled to
participate, including waiving notice of any meeting, or voting or participating
at a meeting. Every proxy must be signed by the Limited Partner or his
attorney-in-fact. No proxy shall be valid after the expiration of twelve (12)
months from the date thereof unless otherwise provided in the proxy. Every proxy
shall be revocable at the pleasure of the Limited Partner executing it, such
revocation to be effective upon the Partnership's receipt of written notice of
such revocation from the Limited Partner executing such proxy.

         D. Each meeting of the Partners shall be conducted by the General
Partner or such other Person as the General Partner may appoint pursuant to such
rules for the conduct of the meeting as the General Partner or such other Person
deems appropriate. Without limitation, meetings of Partners may be conducted in
the same manner as meetings of the shareholders of

                                       53

the Company and may be held at the same time, and as part of, meetings of the
shareholders of the Company.

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective
Date (hereinafter defined), Purchaser shall deliver to Chicago Title Insurance
Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), Ninety-Seven Thousand
Two Hundred Four and No/100 Dollars ($97,204.00) (the "Earnest Money Deposit")
in cash or Current Funds, to be held by the Title Company in escrow to be
applied or disposed of by the Title Company as is provided in this Contract. In
the event Purchaser fails to deposit the Earnest Money Deposit with the Title
Company as herein provided, Seller may, at its option, terminate this Contract,
in which event neither Seller nor Purchaser shall have any further obligations
hereunder except for provisions of this Contract which expressly survive the
termination of this Contract. As used in this Contract, the term "Current Funds"
shall mean wire transfers, certified funds or cashier's checks in a form
acceptable to the Title Company which would permit the Title Company to
immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Seller shall, notwithstanding anything to the contrary contained
herein, satisfy all liens securing the payment of a monetary obligation and
affecting the Property at or prior to Closing, except for any liens or
encumbrances expressly permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion

                                       -3-


<PAGE>



but without any obligation to do so, any objection to the condition of title
raised by Purchaser. If Seller notifies Purchaser that it elects not to cure any
such objections, then Purchaser may, at its option exercisable within five (5)
days following the date of receipt by Purchaser of written notice from Seller
stating that Seller is unable or unwilling to cure such objections, either (a)
accept such title as Seller can deliver, in which case all exceptions to title
set forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (b) terminate this
Contract by notice in writing to Seller in which event the Title Company shall
return the Earnest Money Deposit to Purchaser and neither party shall have any
further rights, duties or obligations hereunder, except for provisions of this
Contract which expressly survive termination of this Contract. In the event
Purchaser fails to notify Seller, within such five (5) day period, that
Purchaser has elected to proceed under either subpart (a) or (b) of the
immediately preceding sentence, Purchaser shall be deemed to have elected to
proceed under subpart (a), and this Contract shall remain in full force and
effect. If Seller notifies Purchaser that it elects to cure any such objections
but is unable to cure same by Closing or if Seller fails to notify Purchaser of
its intentions with respect to such objections and fails to cure same by
Closing, then Purchaser may, at its option, either (x) accept such title as
Seller can deliver in which case the parties shall proceed with Closing and all
exceptions to title set forth in the Title Commitment, Exception Documents and
Survey which are not removed shall be deemed to be Permitted Exceptions, or (y)
terminate this Contract by notice in writing to Seller at Closing, in which
event the Title Company shall return the Earnest Money Deposit to Purchaser and
neither party shall have any further rights, duties or obligations hereunder
except for provisions of this Contract which expressly survive termination of
this Contract. If any additional exceptions to title other than those shown on
the initial Title Commitment or Survey arise between the date of the initial
Title Commitment, the Survey and the Closing (such exceptions to title being
referred to herein as the "New Exceptions"), Purchaser shall have five (5)
business days after its receipt of written notice of such New Exceptions within
which to notify Seller of any such New Exceptions to which Purchaser objects.
Any such New Exceptions not objected to by Purchaser as aforesaid shall become
"Permitted Exceptions" hereunder; provided, however, all New Exceptions created,
caused by, or consented to by Seller shall be satisfied or removed at Closing
and shall not constitute Permitted Exceptions unless such New Exceptions are
expressly permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any
such New Exceptions, Seller shall have until Closing to remove such New
Exceptions, which removal may be accomplished by waiver or endorsement by the
Title Company reasonably satisfactory to Purchaser. If Seller fails to remove
any such New Exceptions as aforesaid, Purchaser may, as its sole and exclusive
remedy, terminate this Contract and obtain a return of the Earnest Money Deposit
and neither party shall have any further rights, duties, or obligations
hereunder except for provisions of the Contract which expressly survive the
termination of this Contract. If Purchaser does not elect to terminate this
Agreement, Purchaser shall consummate the Closing and accept title to the
Property subject to all such New Exceptions (in which event, all such New
Exceptions, together with all other Permitted Exceptions, shall be deemed
"Permitted Exceptions" hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and

                                       -4-


<PAGE>



payable; (c) liens and encumbrances arising after the date hereof to which
Purchaser consents in writing; and (d) any liens or encumbrances of a definite
or ascertainable amount not exceeding $50,000.00 for the Property (and when such
amount is added to the aggregate amounts of any liens or encumbrances to be
insured and bonded around by the respective Dependent Sellers (hereinafter
defined) under the Dependent Contracts (hereinafter defined), such aggregate
amount shall not exceed $125,000.00), provided that (i) Seller causes such liens
or encumbrances to be insured or bonded around such that same do not appear as
an exception in the Title Policy issued to Purchaser pursuant to the Commitment,
and (ii) Seller agrees to indemnify Purchaser from all losses incurred by
Purchaser as a result of such liens or encumbrances.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding,

                                       -5-


<PAGE>



however, any proprietary development or marketing materials), (e) Purchaser
shall not permit any mechanic's or materialman's liens or any other liens to
attach to the Property by reason of the performance of any work or the purchase
of any materials by Purchaser or any other party on Purchaser's behalf in
connection with any studies or tests conducted pursuant to this Section 5.1, (f)
Purchaser shall give notice (which may be by telephone) to Seller a reasonable
time prior to entry onto the Property and shall permit Seller to have a
representative present during all investigations and inspections conducted with
respect to the Property, and (g) Purchaser shall take all reasonable actions and
implement all protections necessary to ensure that all actions taken in
connection with the investigations and inspections of the Property, and all
equipment, materials and substances generated, used or brought onto the Property
pose no material threat to the safety of persons or the environment and cause no
damage to the Property or other property of Seller or other persons. All
information made available by Seller to Purchaser in accordance with this
Contract or obtained by Purchaser in the course of its investigations shall be
treated as confidential information by Purchaser, and, prior to the purchase of
the Property by Purchaser, Purchaser shall use its best efforts to prevent its
agents and employees from divulging such information to any third parties except
(i) as reasonably necessary to third parties engaged by Purchaser for the
limited purpose of analyzing and investigating such information for the purpose
of consummating the transaction contemplated by this Contract, including
Purchaser's attorneys and representatives, prospective lenders and engineers or
(ii) as may required by applicable law, unless such information is generally
available to the public or is disclosed by a party other than Purchaser or its
agents. Purchaser shall indemnify, defend and hold Seller harmless for, from and
against any and all claims, liabilities, causes of action, damages, liens,
losses, costs and expenses (including, without limitation, reasonable attorneys'
fees) incident to, resulting from or in any way arising out of any of
Purchaser's and its agents', contractors' and representatives' activities on the
Property, including, without limitation, any tests or inspections conducted by
Purchaser or its agents, contractors or representatives on the Property. The
agreements contained in this Section 5.1 shall survive the Closing and not be
merged therein and shall also survive any termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service

                                       -6-

the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior to the Closing Date shall be deemed approved by Purchaser
and shall be assumed by Purchaser at Closing.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and


                                      -11-


<PAGE>



                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each Tenant complete, sign and deliver
such Estoppel Certificate to Seller. Seller's only obligation with respect to
such Estoppel Certificates shall be to request that each Tenant complete and
deliver to Seller such Estoppel Certificates. Purchaser's obligations to
consummate the transaction contemplated by this Contract are expressly subject
to and conditioned upon (x) Seller delivering to Purchaser on or before the
Closing Date Estoppel Certificates dated no earlier than thirty (30) days prior
to the Closing Date executed by Tenants occupying at least seventy percent (70%)
of the net rentable area of the Improvements, in the aggregate, and from all
Tenants set forth in Schedule 7.3 attached hereto and made a part hereof (the
"Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer

                                      -12-

have any liability hereunder with respect to the Seller's Certificate relating
to the Tenant Lease in question. The provisions of this Section shall survive
the Closing and delivery of the Deed.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be

Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,

Property, and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,

mortgage taxes or other similar taxes, fees or assessments incurred in
connection with any such financing shall be borne and paid exclusively by
Purchaser. All other expenses incurred by Seller and Purchaser with respect to
the Closing, including, but not limited to, the attorneys' fees and costs and
expenses incurred in connection with negotiating, preparing and closing the
transaction contemplated by this Contract, shall be borne and paid exclusively
by the party incurring same, unless otherwise expressly provided in this

         8.4 Prorations. All normal and customarily proratable items, including,
without limitation, rents (including, without limitation, base rents, additional

due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for
any amounts paid by Seller attributable to the period on or after the Closing
Date) and Purchaser being responsible for, and credited or charged, as the case
may be, for all of same attributable to the period on and after the Closing

the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection with the
proration of real property taxes or installments of assessments, such proration
shall be based upon the assessed valuation and tax rate figures for the year in
which the Closing occurs to the extent the same are available; provided, that in
the event that actual figures (whether for the assessed value of the Property or
for the tax rate) for the year of Closing are not available at the Closing Date,

figures which are unavailable for the year of Closing. All prorations hereunder

Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998,

                                      -17-

Seller has notified Tenants in writing that estimated additional rent payments
(the "1998 Additional Rent Payments") are required to be paid by the Tenants at
such time as base rent payments are due and payable during the balance of the
1998 calendar year. Purchaser agrees that at such time as the 1998 Additional
Rent Payments are received from the Tenants after the Closing Date, Purchaser
shall promptly deliver Seller's Pro rata Portion of such 1998 Additional Rent
Payments to Seller. As used in this Section 8.8, Seller's Pro rata Portion shall
be equal to the amount expressed in percentage terms determined by dividing (x)
the number of days that Seller owned the Property in the 1998 calendar year by
(y) 365. The provisions of this Section 8.8 shall survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights, duties, or obligations hereunder except
         for provisions of this Contract which expressly survive the termination
         of this Contract. If Purchaser does not terminate this Contract as
         aforesaid or the taking is not substantial, then both parties shall
         proceed to close the transaction contemplated herein pursuant to the
         terms hereof, in which event Seller shall, except as limited in Section
         9.1(b) hereof, deliver to Purchaser at the Closing any proceeds
         actually received by Seller attributable to the Property from such
         condemnation, eminent domain proceeding or deed in lieu thereof and
         assign its interest in and to the balance of any unpaid proceeds, and
         there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Eighteen Thousand Two
         Hundred and No/100 Dollars ($118,200.00). Notwithstanding anything in
         Section 9.2(a) to the contrary, if Purchaser has not timely elected to
         terminate in accordance with Section 9.2(a), and if the proceeds
         payable with respect to the Property as a result of casualty exceed the
         Purchase Price for the Property, the portion of such proceeds in excess
         of the Purchase Price shall be paid to Seller (in addition to the
         Purchase Price) at the Closing. The foregoing provision shall survive
         the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by

                                      -19-


<PAGE>



Purchaser of any indemnity under this Contract which survives the Closing or
termination of this Contract, Seller shall have any and all rights and remedies
available at law or in equity by reason of such default, excluding, however, any
punitive, speculative or consequential damages or damages for loss of
opportunity or lost profit. Except as otherwise provided in this Section 10.1,
in no event shall Purchaser be liable to Seller for any damages, including,
without limitation, any actual, punitive, speculative or consequential damages
or damages for loss of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost

                                      -20-


<PAGE>



or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Purchaser by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Seller (including, without limitation, Broker). Purchaser
agrees to indemnify Seller and hold Seller harmless from any loss, liability,
damage, cost or expense (including, without limitation, reasonable attorneys'
fees) arising out of or paid or incurred by Seller by reason of any claim to any
broker's, finder's or other fee in connection with this transaction by any party
claiming by, through or under Purchaser (excluding Broker). Notwithstanding
anything to the contrary contained herein, the indemnities and other provisions
set forth in this Article XI shall survive the Closing or termination of this
Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii) after June 1, 1998, Seller shall
not materially modify or terminate any existing Tenant Lease or grant any
material consents under any existing Tenant Lease (except as otherwise required
pursuant to the terms and conditions of such Tenant Lease), or enter into any
new Tenant Lease, and (iii) Seller shall not apply any then unapplied Deposits
(as reflected on the Rent Roll delivered by Seller to Purchaser pursuant to
Schedule 5.3(vii) hereof) under Tenant Leases); and (b) advise Purchaser of the
commencement of any litigation, condemnation or other judicial or administrative
proceedings affecting the Property of which Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby agrees, for a period of six months after Closing,
         to permit Purchaser and Purchaser's accountants access to such books
         and records (including those maintained by Seller's management agent
         for the Property) and to cooperate with Purchaser, and to cause
         Seller's accountants to cooperate with Purchaser, at no cost to Seller,
         to enable such audit to be performed. The provisions of this Section
         13.17(b) shall survive the Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition

                                      -25-


<PAGE>



         of the properties set forth and described in the Dependent Contracts
         pursuant to the terms and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which entitles Seller to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract shall be promptly paid to Seller and
         the earnest money deposits held under the Dependent Contracts shall be
         promptly paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.


                                      -26-


<PAGE>



         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Forest Abrams Place, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Forest
Abrams Place, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not be released from any representations,
warranties, covenants, agreements or obligations hereunder as a result of the
exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         (the "Existing Note"), in the original principal amount of Three

         executed by Seller and payable to the order of State Farm Life
         Insurance Company, an Illinois corporation (together with its
         successors and assigns referred to herein as the "Existing Lender"),
         (ii) that certain Deed of Trust executed by Seller for the benefit of
         the Existing Lender and dated as of even date with the Existing Note
         (the "Existing Deed of Trust"), and (iii) all other documents,
         instruments and agreements securing payment of the Existing Note or
         related to the Existing Note or the Existing Deed of Trust (the
         Existing Note, the Existing Deed of Trust and any and all notes, deeds

         to Purchaser or identified in the Assumption Agreement (hereinafter
         defined), as the same may have been or may hereafter be amended,

         it is understood and agreed that all funds held by the Existing Lender
         in any escrow, reserve or similar accounts pursuant to the terms of the
         Existing Loan Documents (the "Existing Escrow Accounts") are held for

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective
Date (hereinafter defined), Purchaser shall deliver to Chicago Title Insurance
Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), Two Hundred Eighty-Four
Thousand Eight Hundred Sixty-Eight and No/100 Dollars ($284,868.00) (the
"Earnest Money Deposit") in cash or Current Funds, to be held by the Title
Company in escrow to be applied or disposed of by the Title Company as is
provided in this Contract. In the event Purchaser fails to deposit the Earnest
Money Deposit with the Title Company as herein provided, Seller may, at its
option, terminate this Contract, in which event neither Seller nor Purchaser
shall have any further obligations hereunder except for provisions of this
Contract which expressly survive the termination of this Contract. As used in
this Contract, the term "Current Funds" shall mean wire transfers, certified
funds or cashier's checks in a form acceptable to the Title Company which would
permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title

                                       -3-


<PAGE>



to the Land and Improvements specified in the Title Commitment. At such time as
the Title Commitment is furnished to Purchaser, the Title Company also shall
furnish to Purchaser copies of instruments or documents (the "Exception
Documents") that create or evidence conditions or exceptions to title affecting
the Land and Improvements, as described in the Title Commitment.

         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five

                                       -4-


<PAGE>



(5) day period, that Purchaser has elected to proceed under either subpart (a)
or (b) of the immediately preceding sentence, Purchaser shall be deemed to have
elected to proceed under subpart (a), and this Contract shall remain in full
force and effect. If Seller notifies Purchaser that it elects to cure any such
objections but is unable to cure same by Closing or if Seller fails to notify
Purchaser of its intentions with respect to such objections and fails to cure
same by Closing, then Purchaser may, at its option, either (x) accept such title
as Seller can deliver in which case the parties shall proceed with Closing and
all exceptions to title set forth in the Title Commitment, Exception Documents
and Survey which are not removed shall be deemed to be Permitted Exceptions, or
(y) terminate this Contract by notice in writing to Seller at Closing, in which
event the Title Company shall return the Earnest Money Deposit to Purchaser and
neither party shall have any further rights, duties or obligations hereunder
except for provisions of this Contract which expressly survive termination of
this Contract. If any additional exceptions to title other than those shown on
the initial Title Commitment or Survey arise between the date of the initial
Title Commitment, the Survey and the Closing (such exceptions to title being
referred to herein as the "New Exceptions"), Purchaser shall have five (5)
business days after its receipt of written notice of such New Exceptions within
which to notify Seller of any such New Exceptions to which Purchaser objects.
Any such New Exceptions not objected to by Purchaser as aforesaid shall become
"Permitted Exceptions" hereunder; provided, however, all New Exceptions created,
caused by, or consented to by Seller shall be satisfied or removed at Closing
and shall not constitute Permitted Exceptions unless such New Exceptions are
expressly permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any
such New Exceptions, Seller shall have until Closing to remove such New
Exceptions, which removal may be accomplished by waiver or endorsement by the
Title Company reasonably satisfactory to Purchaser. If Seller fails to remove
any such New Exceptions as aforesaid, Purchaser may, as its sole and exclusive
remedy, terminate this Contract and obtain a return of the Earnest Money Deposit
and neither party shall have any further rights, duties, or obligations
hereunder except for provisions of the Contract which expressly survive the
termination of this Contract. If Purchaser does not elect to terminate this
Agreement, Purchaser shall consummate the Closing and accept title to the
Property subject to all such New Exceptions (in which event, all such New
Exceptions, together with all other Permitted Exceptions, shall be deemed
"Permitted Exceptions" hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents

the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-


<PAGE>



environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

                                       -7-

         relating to the Property;

                  (vii) An updated certified rent roll reflecting all payments
         made by Tenants under Tenants Leases through May 25, 1998.

                  The items identified in (i)-(vii) hereinabove are collectively
         referred to as the "Submission Matters".

         Seller shall allow Purchaser to review and make copies of any other
documents, instruments or agreements it has with respect to the Property at
Seller's offices; provided that, in no event shall Purchaser be allowed to
review any documents which constitute or would be covered by the attorney-client
privilege or the 1998 budgets prepared by or for Seller with respect to the
Property.

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-


<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing
Date").

         8.2      Items to be Delivered at the Closing.

                  (a) Seller. At the Closing, Seller shall deliver, or cause to
         be delivered, to the Title Company for recording or delivery to
         Purchaser, as applicable, each of the following items:

                  Insurance dated no earlier than the date of the filing of the
                  Deed described in Section 8.2(a)(ii) hereof, issued by the
                  Title Company for the benefit of and at the expense of
                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid
exclusively by Purchaser. All other expenses incurred by Seller and Purchaser

due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for

with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value

All prorations hereunder shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new

Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after

provide services to the Property.

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Three Hundred Forty-Six Thousand Four
         Hundred Dollars ($346,400.00). Notwithstanding anything in Section
         9.2(a) to the contrary, if

                                      -20-


<PAGE>



         Purchaser has not timely elected to terminate in accordance with
         Section 9.2(a), and if the proceeds payable with respect to the
         Property as a result of casualty exceed the Purchase Price for the
         Property, the portion of such proceeds in excess of the Purchase Price
         shall be paid to Seller (in addition to the Purchase Price) at the
         Closing. The foregoing provision shall survive the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-


<PAGE>



after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

         13.4 Parties Bound. Subject to the provisions of Section 13.5 hereof,
this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's
option, be null and void and of no effect. In the event of an assignment of this
Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of
the Deed by Seller to Purchaser.

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are
references to exhibits attached hereto, all of which are hereby made a part
hereof for all purposes.

         13.10 Time of Essence. It is expressly agreed by the parties hereto
that time is of the essence with respect to this Contract and Closing hereunder.

         13.11 Multiple Counterparts. This Contract may be executed in a number
of identical counterparts. If so executed, each of such counterparts is to be
deemed an original for all purposes, and all such counterparts shall,
collectively, constitute one agreement, but, in making proof of this Contract,

counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part
thereof, by fire or any other casualty from the date this Contract is fully
executed up to the time of delivering the Deed transferring title to the

initialed by Purchaser and Seller.

         13.14 Business Days. All references to "business days" contained herein
are references to normal working business days, i.e., Monday through Friday of
each calendar week, exclusive of federal and national bank holidays. In the
event that any event hereunder is to occur, or a time period is to expire, on a
date which is not a business day, such event shall occur or such time period
shall expire on the next succeeding business day.

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which

shall cooperate with one another at reasonable times and on reasonable
conditions and shall execute and deliver such instruments and documents as may
be necessary in order fully to carry out the intent and purposes of the
transactions contemplated hereby. Except for such instruments and documents as
the parties were originally obligated to deliver by the terms of this Contract,
such cooperation shall be without additional cost or liability. The provisions
of this Section 13.16 shall survive the Closing for a period of one year.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-


<PAGE>



         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which

                                      -27-


<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Greenville Avenue Properties, Ltd.
will remain obligated as the Seller under this Contract, and all
representations, warranties, covenants, agreements and obligations which survive
the Closing and are binding upon the Seller hereunder shall survive and continue
as representations, warranties, covenants, agreements and obligations of
Greenville Avenue Properties, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-


<PAGE>



be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), Four Hundred Thirty-Five Thousand Eight Hundred Fifty
Five and No/100 Dollars ($435,855.00) (the "Earnest Money Deposit") in cash or
Current Funds, to be held by the Title Company in escrow to be applied or
disposed of by the Title Company as is provided in this Contract. In the event
Purchaser fails to deposit the Earnest Money Deposit with the Title Company as
herein provided, Seller may, at its option, terminate this Contract, in which
event neither Seller nor Purchaser shall have any further obligations hereunder
except for provisions of this Contract which expressly survive the termination
of this Contract. As used in this Contract, the term "Current Funds" shall mean
wire transfers, certified funds or cashier's checks in a form acceptable to the
Title Company which would permit the Title Company to immediately disburse such
funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-


<PAGE>



may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-

environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND

                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a)      The representations and warranties of Seller 
         contained herein shall be true, accurate and correct as of the Closing
         Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a)      the representations and warranties of Purchaser 
         contained herein shall be true, accurate and correct as of the Closing
         Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-


<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing
Date").

                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                           (ii) A Special Warranty Deed (the "Deed") duly

                  hereto as Exhibit B and made a part hereof for all purposes
                  sufficient to convey to Purchaser good and indefeasible title
                  to the Land and Improvements free and clear of all liens and
                  encumbrances except for the Permitted Exceptions.

                           (iii) An Assignment and Assumption of Leases and
                  Commission Agreements (the "Assignment of Leases") duly

                  hereto as Exhibit C and made a part hereof for all purposes.

                  transfer of the Property, confirming the assumption and
                  modification of the Existing Loan and confirming that Seller
                  is not in default under the Existing Loan Documents, all in
                  form and substance reasonably satisfactory to Purchaser.

                           (xix) Evidence that Broker (hereinafter defined) has
                  or will be paid at Closing the brokerage commissions referred
                  to in Section 11.1 hereof.

                           (xx) A management agreement for the Property and all
                  of the properties under the Dependent Contracts executed by
                  Breunig Commercial Management, Inc. in form and substance
                  reasonably acceptable to Purchaser and Breunig Commercial
                  Management, Inc. (the "Management Agreement"), which
                  Management Agreement shall have a term of one year, be
                  terminable by Purchaser after six months without cause or
                  premium, have a management fee of five percent (5%), pay
                  standard leasing commissions and require Purchaser to pay
                  $300,000 to such manager for use exclusively as bonuses to
                  employees of such manager that are dedicated to property level
                  services including, without limitation, accounting and leasing
                  services, with no more than $150,000 of such bonuses being
                  paid prior to the date that is six months after the Closing,
                  provided, however, if Purchaser acquires less than all of the
                  properties under this Contract and the Dependent Contracts
                  pursuant to Section 14.1(f) hereof, then Purchaser shall be
                  entitled to reduce such $300,000 figure on a pro rata basis
                  based upon the purchase prices of the properties not acquired
                  under this Contract and the Dependent Contracts to the
                  aggregate purchase prices of all of the properties under this
                  Contract and the Dependent Contracts.

         (b)      Purchaser. At the Closing, Purchaser shall deliver to the
                  Title Company, for recording or delivery to Seller, as
                  applicable, each of the following items:

                           (i)      The Purchase Price in Current Funds.

                           (ii) The Assignment of Leases, duly executed and
                  acknowledged by Purchaser.

                           (iii) The Bill of Sale, duly executed by Purchaser.

                           (iv) Such additional funds in cash or Current Funds,
                  as may be necessary to cover Purchaser's share of the closing
                  costs and prorations hereunder.

                           (v) Evidence satisfactory to Seller and the Title
                  Company that the person or persons executing this Contract and
                  the closing documents on behalf of Purchaser have full right,
                  power and authority to do so.

                           (vi) The Notice Letters and Service Contract Notice

                  Company for the sale of the Property in accordance with this
                  Contract or for administrative requirements for consummating
                  the Closing.

                           (viii)           The Management Agreement executed 
                  by Purchaser.

                           (ix)     The Assumption Agreement executed by 
                  Purchaser.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be
paid equally by Seller and Purchaser. Any and all costs relating to the Title
Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,
relating to (a) any financing obtained by the Purchaser for the purchase of the
Property (including, without limitation, any loan assumption fees and expenses
charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid
exclusively by Purchaser. All other expenses incurred by Seller and Purchaser
with respect to the Closing, including, but not limited to, the attorneys' fees
and costs and expenses incurred in connection with negotiating, preparing and
closing the transaction contemplated by this Contract, shall be borne and paid
exclusively by the party incurring same, unless otherwise expressly provided in
this Contract.

         8.4 Prorations. All normal and customarily proratable items, including,
without limitation, rents (including, without limitation, base rents, additional
rents, percentage rents and common area maintenance charges but excluding
Delinquent Rent [hereinafter defined] that is more than thirty (30) days past
due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for
any amounts paid by Seller attributable to the period on or after the Closing
Date) and Purchaser being responsible for, and credited or charged, as the case
may be, for all of same attributable to the period on and after the Closing
Date. All unapplied Deposits under Tenant Leases, if any, and all prepaid rents
paid by Tenants under Tenant Leases (but only to the extent such rents are for
periods from and after the Closing Date) shall be credited to Purchaser against
the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection

                                      -17-


<PAGE>



with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value
of the Property or for the tax rate) for the year of Closing are not available
at the Closing Date, the proration shall be made using figures from the
preceding year for the figures which are unavailable for the year of Closing.
All prorations hereunder shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new
Tenant Leases entered into by Seller after June 1, 1998 and prior to the Closing
Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                                      -18-


<PAGE>



                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Five Hundred Thirty Thousand and No/100
         Dollars ($530,000.00). Notwithstanding anything in Section 9.2(a) to
         the contrary, if

                                      -20-


<PAGE>



         Purchaser has not timely elected to terminate in accordance with
         Section 9.2(a), and if the proceeds payable with respect to the
         Property as a result of casualty exceed the Purchase Price for the
         Property, the portion of such proceeds in excess of the Purchase Price
         shall be paid to Seller (in addition to the Purchase Price) at the
         Closing. The foregoing provision shall survive the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-


<PAGE>



after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such

this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's

Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of
the Deed by Seller to Purchaser.

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are

         13.11 Multiple Counterparts. This Contract may be executed in a number

counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part

are references to normal working business days, i.e., Monday through Friday of
each calendar week, exclusive of federal and national bank holidays. In the

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which

of this Section 13.16 shall survive the Closing for a period of one year.

         13.17             Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-


<PAGE>



         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which

                                      -27-


<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Northcreek Place II, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Northcreek
Place II, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-


<PAGE>



be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

                                            SELLER:

Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), Six Hundred Three Thousand Two Hundred Eighty-Nine and
No/100 Dollars ($603,289.00) (the "Earnest Money Deposit") in cash or Current
Funds, to be held by the Title Company in escrow to be applied or disposed of by
the Title Company as is provided in this Contract. In the event Purchaser fails
to deposit the Earnest Money Deposit with the Title Company as herein provided,
Seller may, at its option, terminate this Contract, in which event neither
Seller nor Purchaser shall have any further obligations hereunder except for
provisions of this Contract which expressly survive the termination of this
Contract. As used in this Contract, the term "Current Funds" shall mean wire
transfers, certified funds or cashier's checks in a form acceptable to the Title
Company which would permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-


<PAGE>



may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-

environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall

of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-


<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing

                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                           (ii) A Special Warranty Deed (the "Deed") duly

                  sufficient to convey to Purchaser good and indefeasible title
                  to the Land and Improvements free and clear of all liens and
                  encumbrances except for the Permitted Exceptions.

                  hereto as Exhibit C and made a part hereof for all purposes.

                                      -17-


<PAGE>



with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value
of the Property or for the tax rate) for the year of Closing are not available
at the Closing Date, the proration shall be made using figures from the
preceding year for the figures which are unavailable for the year of Closing.
All prorations hereunder shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new
Tenant Leases entered into by Seller after June 1, 1998 and prior to the Closing
Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.


                                      -18-


<PAGE>



                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1 Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Seven Hundred Thirty-Three Thousand Six
         Hundred and No/100 Dollars ($733,600.00). Notwithstanding anything in
         Section 9.2(a) to

                                      -20-


<PAGE>



         the contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

<PAGE>



         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-


<PAGE>



after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge. Notwithstanding the foregoing, Purchaser
acknowledges that Seller is currently negotiating with Healthtech Rehab over
outstanding Tenant improvement expenditures and past due rents. Purchaser agrees
that Seller shall be entitled to settle and compromise such disputes provided
that there are no material amendments to such lease (other than a reduction in
the amount of tenant improvement expenditures due and owing to such Tenant under
such Lease) and Seller shall not be entitled to terminate such Lease.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

                                  ARTICLE XIII.

         13.3 Entirety and Amendments. This Contract embodies the entire
agreement between the parties and supersedes all prior agreements and
understandings, if any, relating to the transaction described herein, and may be
amended or supplemented only by an instrument in writing executed by the party

assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with

Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference

construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part
thereof, by fire or any other casualty from the date this Contract is fully
executed up to the time of delivering the Deed transferring title to the

Purchaser.

         13.13 Effective Date. As used herein, the term "Effective Date" shall

of this Section 13.16 shall survive the Closing for a period of one year.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this

         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby agrees, for a period of six months after Closing,
         to permit Purchaser and Purchaser's accountants access to such books
         and records (including those maintained by Seller's management agent
         for the Property) and to cooperate with Purchaser, and to cause
         Seller's accountants to cooperate with Purchaser, at no cost to Seller,
         to enable such audit to be performed. The provisions of this Section
         13.17(b) shall survive the Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;


                                      -27-


<PAGE>



                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which entitles Seller to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract shall be promptly paid to Seller and
         the earnest money deposits held under the Dependent Contracts shall be
         promptly paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, One Glen Lakes, Ltd. will remain
obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of One Glen
Lakes, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and

                                      -28-


<PAGE>



in such event only Seller shall remain obligated to consummate the transaction
contemplated in this Contract; (c) Seller shall reimburse Purchaser for any and
all costs reasonably incurred by Purchaser as a result of the exchange or
attempted exchange; (d) Purchaser need not assume any additional liabilities or
obligations as a result of the exchange or attempted exchange; and (e) Seller
shall not be released from any representations, warranties, covenants,
agreements or obligations hereunder as a result of the exchange or attempted
exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

                                    SELLER:

                   [Crosspoint Atrium Building, Dallas, Texas]

         THIS CONTRACT OF SALE (this "Contract") is made and entered into by and
between CROSSPOINT ATRIUM, LTD., a Texas limited partnership ("Seller") and
BEACON CAPITAL PARTNERS, L.P., a Delaware limited partnership ("Purchaser").

                                   ARTICLE I.

                              SALE OF THE PROPERTY

         1.1 Property. For the consideration and upon and subject to the terms,

and Purchaser agrees to purchase from Seller, Seller's respective rights, titles
and interests in and to all of the following described property (collectively,

                  (a) All of Seller's rights, titles and interests in and to
         that certain tract or parcel of land (the "Land") located in Dallas
         County, Texas, more particularly described on Exhibit A attached hereto
         and made a part hereof for all purposes, together with all
         improvements, structures and fixtures, if any, located on the Land (the
         "Improvements"), and all rights, titles and interests of Seller
         appurtenant to the Land and Improvements, including, without
         limitation, appurtenant easements, adjacent roads, highways and
         rights-of-way;

                  (b) All tangible and intangible personal property of any kind
         (the "Personalty") owned by Seller and attached to or located on or
         used in connection with the Land or Improvements including, without
         limitation, those items of tangible personal property set forth on the
         Personal Property Schedule (hereinafter defined);

                  (c) All of Seller's rights, titles and interests under any
         leases or other agreements demising space in or providing for the use
         or occupancy of the Improvements or Land (the "Tenant Leases"), and all
         unapplied deposits, whether security or otherwise ("Deposits"), paid by
         tenants ("Tenants") under the Tenant Leases and all of Seller's rights,
         titles and interests in and to all leasing commission agreements (the
         "Commission Agreements") relating to the Tenant Leases that Purchaser

<PAGE>



                                   ARTICLE II.

                                 PURCHASE PRICE

         2.1 Purchase Price. The total Purchase Price (herein so called) to be
paid by Purchaser to Seller for the Property shall be an amount equal to
Eighteen Million Ninety Thousand and No/100 Dollars ($18,090,000.00). The
Purchase Price shall be payable in cash or Current Funds (hereinafter defined)
at Closing.

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective
Date (hereinafter defined), Purchaser shall deliver to Chicago Title Insurance
Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), Five Hundred
Ninety-Five Thousand Sixty-Six and No/100 Dollars ($595,066.00) (the "Earnest
Money Deposit") in cash or Current Funds, to be held by the Title Company in
escrow to be applied or disposed of by the Title Company as is provided in this
Contract. In the event Purchaser fails to deposit the Earnest Money Deposit with
the Title Company as herein provided, Seller may, at its option, terminate this
Contract, in which event neither Seller nor Purchaser shall have any further
obligations hereunder except for provisions of this Contract which expressly
survive the termination of this Contract. As used in this Contract, the term
"Current Funds" shall mean wire transfers, certified funds or cashier's checks
in a form acceptable to the Title Company which would permit the Title Company
to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Seller shall, notwithstanding anything to the contrary contained
herein, satisfy all liens securing the payment of a monetary obligation and
affecting the Property at or prior to Closing, except for any liens or
encumbrances expressly permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion

                                       -3-

but without any obligation to do so, any objection to the condition of title
raised by Purchaser. If Seller notifies Purchaser that it elects not to cure any
such objections, then Purchaser may, at its option exercisable within five (5)
days following the date of receipt by Purchaser of written notice from Seller
stating that Seller is unable or unwilling to cure such objections, either (a)
accept such title as Seller can deliver, in which case all exceptions to title
set forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (b) terminate this
Contract by notice in writing to Seller in which event the Title Company shall
return the Earnest Money Deposit to Purchaser and neither party shall have any
further rights, duties or obligations hereunder, except for provisions of this
Contract which expressly survive termination of this Contract. In the event
Purchaser fails to notify Seller, within such five (5) day period, that
Purchaser has elected to proceed under either subpart (a) or (b) of the
immediately preceding sentence, Purchaser shall be deemed to have elected to
proceed under subpart (a), and this Contract shall remain in full force and
effect. If Seller notifies Purchaser that it elects to cure any such objections
but is unable to cure same by Closing or if Seller fails to notify Purchaser of
its intentions with respect to such objections and fails to cure same by
Closing, then Purchaser may, at its option, either (x) accept such title as
Seller can deliver in which case the parties shall proceed with Closing and all
exceptions to title set forth in the Title Commitment, Exception Documents and
Survey which are not removed shall be deemed to be Permitted Exceptions, or (y)
terminate this Contract by notice in writing to Seller at Closing, in which
event the Title Company shall return the Earnest Money Deposit to Purchaser and
neither party shall have any further rights, duties or obligations hereunder
except for provisions of this Contract which expressly survive termination of
this Contract. If any additional exceptions to title other than those shown on
the initial Title Commitment or Survey arise between the date of the initial
Title Commitment, the Survey and the Closing (such exceptions to title being
referred to herein as the "New Exceptions"), Purchaser shall have five (5)
business days after its receipt of written notice of such New Exceptions within
which to notify Seller of any such New Exceptions to which Purchaser objects.
Any such New Exceptions not objected to by Purchaser as aforesaid shall become
"Permitted Exceptions" hereunder; provided, however, all New Exceptions created,
caused by, or consented to by Seller shall be satisfied or removed at Closing
and shall not constitute Permitted Exceptions unless such New Exceptions are
expressly permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any
such New Exceptions, Seller shall have until Closing to remove such New
Exceptions, which removal may be accomplished by waiver or endorsement by the
Title Company reasonably satisfactory to Purchaser. If Seller fails to remove
any such New Exceptions as aforesaid, Purchaser may, as its sole and exclusive
remedy, terminate this Contract and obtain a return of the Earnest Money Deposit
and neither party shall have any further rights, duties, or obligations
hereunder except for provisions of the Contract which expressly survive the
termination of this Contract. If Purchaser does not elect to terminate this
Agreement, Purchaser shall consummate the Closing and accept title to the
Property subject to all such New Exceptions (in which event, all such New
Exceptions, together with all other Permitted Exceptions, shall be deemed
"Permitted Exceptions" hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and

                                       -4-


<PAGE>



payable; (c) liens and encumbrances arising after the date hereof to which
Purchaser consents in writing; and (d) any liens or encumbrances of a definite
or ascertainable amount not exceeding $50,000.00 for the Property (and when such
amount is added to the aggregate amounts of any liens or encumbrances to be
insured and bonded around by the respective Dependent Sellers (hereinafter
defined) under the Dependent Contracts (hereinafter defined), such aggregate
amount shall not exceed $125,000.00), provided that (i) Seller causes such liens
or encumbrances to be insured or bonded around such that same do not appear as
an exception in the Title Policy issued to Purchaser pursuant to the Commitment,
and (ii) Seller agrees to indemnify Purchaser from all losses incurred by
Purchaser as a result of such liens or encumbrances.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding,

                                       -5-


<PAGE>



however, any proprietary development or marketing materials), (e) Purchaser
shall not permit any mechanic's or materialman's liens or any other liens to
attach to the Property by reason of the performance of any work or the purchase
of any materials by Purchaser or any other party on Purchaser's behalf in
connection with any studies or tests conducted pursuant to this Section 5.1, (f)
Purchaser shall give notice (which may be by telephone) to Seller a reasonable
time prior to entry onto the Property and shall permit Seller to have a
representative present during all investigations and inspections conducted with
respect to the Property, and (g) Purchaser shall take all reasonable actions and
implement all protections necessary to ensure that all actions taken in
connection with the investigations and inspections of the Property, and all
equipment, materials and substances generated, used or brought onto the Property
pose no material threat to the safety of persons or the environment and cause no
damage to the Property or other property of Seller or other persons. All
information made available by Seller to Purchaser in accordance with this
Contract or obtained by Purchaser in the course of its investigations shall be
treated as confidential information by Purchaser, and, prior to the purchase of
the Property by Purchaser, Purchaser shall use its best efforts to prevent its
agents and employees from divulging such information to any third parties except
(i) as reasonably necessary to third parties engaged by Purchaser for the
limited purpose of analyzing and investigating such information for the purpose
of consummating the transaction contemplated by this Contract, including
Purchaser's attorneys and representatives, prospective lenders and engineers or
(ii) as may required by applicable law, unless such information is generally
available to the public or is disclosed by a party other than Purchaser or its
agents. Purchaser shall indemnify, defend and hold Seller harmless for, from and
against any and all claims, liabilities, causes of action, damages, liens,
losses, costs and expenses (including, without limitation, reasonable attorneys'
fees) incident to, resulting from or in any way arising out of any of
Purchaser's and its agents', contractors' and representatives' activities on the
Property, including, without limitation, any tests or inspections conducted by
Purchaser or its agents, contractors or representatives on the Property. The
agreements contained in this Section 5.1 shall survive the Closing and not be
merged therein and shall also survive any termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service

                                       -6-


<PAGE>



Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior to the Closing Date shall be deemed approved by Purchaser
and shall be assumed by Purchaser at Closing.

         5.3 Matters to be Delivered by Seller. Seller has previously delivered
to Purchaser and Purchaser hereby acknowledges receipt of the following items:

                  (i) A current rent roll for the Property in the form attached

         Agreements relating to the Property;

         Seller shall allow Purchaser to review and make copies of any other
documents, instruments or agreements it has with respect to the Property at

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND

                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a)      The representations and warranties of Seller 
         contained herein shall be true, accurate and correct as of the Closing
         Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a)      the representations and warranties of Purchaser 
         contained herein shall be true, accurate and correct as of the Closing
         Date; and

                                      -11-


<PAGE>



                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each Tenant complete, sign and deliver
such Estoppel Certificate to Seller. Seller's only obligation with respect to
such Estoppel Certificates shall be to request that each Tenant complete and
deliver to Seller such Estoppel Certificates. Purchaser's obligations to
consummate the transaction contemplated by this Contract are expressly subject
to and conditioned upon (x) Seller delivering to Purchaser on or before the
Closing Date Estoppel Certificates dated no earlier than thirty (30) days prior
to the Closing Date, executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to

         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights, duties, or obligations hereunder except
         for provisions of this Contract which expressly survive the termination
         of this Contract. If Purchaser does not terminate this Contract as
         aforesaid or the taking is not substantial, then both parties shall
         proceed to close the transaction contemplated herein pursuant to the
         terms hereof, in which event Seller shall, except as limited in Section
         9.1(b) hereof, deliver to Purchaser at the Closing any proceeds
         actually received by Seller attributable to the Property from such
         condemnation, eminent domain proceeding or deed in lieu thereof and
         assign its interest in and to the balance of any unpaid proceeds, and
         there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property

                                      -18-


<PAGE>



         as a result of condemnation exceed the Purchase Price for the Property,
         the portion of such proceeds in excess of the Purchase Price shall be
         paid to Seller (in addition to the Purchase Price) at the Closing. The
         foregoing provision shall survive the Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Seven Hundred Twenty-Three Thousand Six
         Hundred and No/100 Dollars ($723,600.00). Notwithstanding anything in
         Section 9.2(a) to the contrary, if Purchaser has not timely elected to
         terminate in accordance with Section 9.2(a), and if the proceeds
         payable with respect to the Property as a result of casualty exceed the
         Purchase Price for the Property, the portion of such proceeds in excess
         of the Purchase Price shall be paid to Seller (in addition to the
         Purchase Price) at the Closing. The foregoing provision shall survive
         the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and

                                      -19-


<PAGE>



Seller shall be entitled to receive and retain the Earnest Money Deposit as
liquidated damages (Seller and Purchaser hereby acknowledging that the amount of
damages in the event of Purchaser's default is difficult or impossible to
ascertain but that such amount is a fair estimate of such damage).
Notwithstanding anything contained in this section to the contrary, in the event
of any default by Purchaser of any indemnity under this Contract which survives
the Closing or termination of this Contract, Seller shall have any and all
rights and remedies available at law or in equity by reason of such default,
excluding, however, any punitive, speculative or consequential damages or
damages for loss of opportunity or lost profit. Except as otherwise provided in
this Section 10.1, in no event shall Purchaser be liable to Seller for any
damages, including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and

                                      -20-


<PAGE>



warrants to Purchaser that Broker shall have no right to receive this commission
or any other amount with respect to this Contract or the Property unless and
until Closing shall be final and fully consummated and Seller shall have
received the Purchase Price as provided in this Contract. Seller agrees to
indemnify Purchaser and hold Purchaser harmless from any loss, liability,
damage, cost or expense (including, without limitation, reasonable attorneys'
fees) arising out of or paid or incurred by Purchaser by reason of any claim to
any broker's, finder's or other fee in connection with this transaction by any
party claiming by, through or under Seller (including, without limitation,
Broker). Purchaser agrees to indemnify Seller and hold Seller harmless from any
loss, liability, damage, cost or expense (including, without limitation,
reasonable attorneys' fees) arising out of or paid or incurred by Seller by
reason of any claim to any broker's, finder's or other fee in connection with
this transaction by any party claiming by, through or under Purchaser (excluding
Broker). Notwithstanding anything to the contrary contained herein, the
indemnities and other provisions set forth in this Article XI shall survive the
Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii) after June 1, 1998, Seller shall
not materially modify or terminate any existing Tenant Lease or grant any
material consents under any existing Tenant Lease (except as otherwise required
pursuant to the terms and conditions of such Tenant Lease), or enter into any
new Tenant Lease, and (iii) Seller shall not apply any then unapplied Deposits
(as reflected on the Rent Roll delivered by Seller to Purchaser pursuant to
Schedule 5.3(vii) hereof) under Tenant Leases); and (b) advise Purchaser of the
commencement of any litigation, condemnation or other judicial or administrative
proceedings affecting the Property of which Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser

                                      -21-

         13.3 Entirety and Amendments. This Contract embodies the entire

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are
references to exhibits attached hereto, all of which are hereby made a part
hereof for all purposes.

         13.10 Time of Essence. It is expressly agreed by the parties hereto
that time is of the essence with respect to this Contract and Closing hereunder.

         13.11 Multiple Counterparts. This Contract may be executed in a number
of identical counterparts. If so executed, each of such counterparts is to be
deemed an original for all purposes, and all such counterparts shall,
collectively, constitute one agreement, but, in making proof of this Contract,
it shall not be necessary to produce or account for more than one such
counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part
thereof, by fire or any other casualty from the date this Contract is fully
executed up to the time of delivering the Deed transferring title to the

Purchaser.

         13.13 Effective Date. As used herein, the term "Effective Date" shall
mean for all purposes in this Contract the date on which the Title Company
acknowledges receipt of an original of the Contract executed by Purchaser and
Seller with all changes, if any, to the printed portion of this Contract
initialed by Purchaser and Seller.

         13.14 Business Days. All references to "business days" contained herein

each calendar week, exclusive of federal and national bank holidays. In the
event that any event hereunder is to occur, or a time period is to expire, on a
date which is not a business day, such event shall occur or such time period
shall expire on the next succeeding business day.

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which

         13.16 Post-Closing Obligations. After the Closing, Seller and Purchaser
shall cooperate with one another at reasonable times and on reasonable
conditions and shall execute and deliver such instruments and documents as may
be necessary in order fully to carry out the intent and purposes of the
transactions contemplated hereby. Except for such instruments and documents as
the parties were originally obligated to deliver by the terms of this Contract,
such cooperation shall be without additional cost or liability. The provisions
of this Section 13.16 shall survive the Closing for a period of one year.

         13.17             Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby agrees, for a period of six months after Closing,
         to permit Purchaser and Purchaser's accountants access to such books
         and records (including those maintained by Seller's management agent
         for the Property) and to cooperate with Purchaser, and to cause
         Seller's accountants to cooperate with Purchaser, at no cost to Seller,
         to enable such audit to be performed. The provisions of this Section
         13.17(b) shall survive the Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                                      -25-


<PAGE>



                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the

         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which entitles Seller to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract shall be promptly paid to Seller and
         the earnest money deposits held under the Dependent Contracts shall be
         promptly paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

                                      -26-

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Crosspoint Atrium, Ltd. will remain
obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Crosspoint
Atrium, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not be released from any representations,
warranties, covenants, agreements or obligations hereunder as a result of the
exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

Price shall be payable by Purchaser at Closing as follows:

                  (a) by the payment by Purchaser of cash or Current Funds

         unpaid interest, of the Existing Note (defined below) as of the date of
         the Closing; and

                  (b) by Purchaser assuming all of the obligations of Seller
         under (i) that certain Promissory Note dated as of November 8, 1994
         (the "Existing Note"), in the original principal amount of One Million
         Six Hundred Twenty-Five and No/100 Dollars ($1,625,000.00), executed by
         Seller and payable to the order of Lutheran Brotherhood (together with

         Existing Note (the "Existing Deed of Trust"), and (iii) all other
         documents, instruments and agreements securing payment of the Existing
         Note or related to the Existing Note or the Existing Deed of Trust (the
         Existing Note, the Existing Deed of Trust and any and all notes, deeds

         to Purchaser or identified in the Assumption Agreement (hereinafter
         defined), as the same may have been or may hereafter be amended,
         supplemented, renewed, extended or restated, shall collectively be
         referred to herein as the "Existing Loan Documents," and all
         indebtedness evidenced by the Existing Loan Documents shall be referred
         to herein as the "Existing Loan"). Notwithstanding the Purchaser's
         assumption of Seller's obligations under the Existing Loan Documents,
         it is understood and agreed that all funds held by the Existing Lender
         in any escrow, reserve or similar accounts pursuant to the terms of the
         Existing Loan Documents (the "Existing Escrow Accounts") are held for
         the benefit of Seller, and at Closing the Purchaser shall be obligated
         to pay to Seller the total amounts held in all such accounts as of the
         Closing Date. All amounts held in the Existing Escrow Accounts shall be
         paid by Purchaser to Seller at the Closing in cash.

<PAGE>



Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), One Hundred Seventy-Seven Thousand Six Hundred Thirty-Two
and No/100 Dollars ($177,632.00) (the "Earnest Money Deposit") in cash or
Current Funds, to be held by the Title Company in escrow to be applied or
disposed of by the Title Company as is provided in this Contract. In the event
Purchaser fails to deposit the Earnest Money Deposit with the Title Company as
herein provided, Seller may, at its option, terminate this Contract, in which
event neither Seller nor Purchaser shall have any further obligations hereunder
except for provisions of this Contract which expressly survive the termination
of this Contract. As used in this Contract, the term "Current Funds" shall mean
wire transfers, certified funds or cashier's checks in a form acceptable to the
Title Company which would permit the Title Company to immediately disburse such
funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-
<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser


                                       -4-
<PAGE>



may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the


                                       -6-
<PAGE>



environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each


                                      -12-
<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with


                                      -13-
<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing

                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                           (ii) A Special Warranty Deed (the "Deed") duly

                  sufficient to convey to Purchaser good and indefeasible title
                  to the Land and Improvements free and clear of all liens and
                  encumbrances except for the Permitted Exceptions.

                           (iii) An Assignment and Assumption of Leases and
                  Commission Agreements (the "Assignment of Leases") duly

                  hereto as Exhibit C and made a part hereof for all purposes.

                  modification of the Existing Loan and confirming that Seller
                  is not in default under the Existing Loan Documents, all in
                  form and substance reasonably satisfactory to Purchaser.

                           (xix) Evidence that Broker (hereinafter defined) has
                  or will be paid at Closing the brokerage commissions referred
                  to in Section 11.1 hereof.

                           (xx) A management agreement for the Property and all
                  of the properties under the Dependent Contracts executed by
                  Breunig Commercial Management, Inc. in form and substance
                  reasonably acceptable to Purchaser and Breunig Commercial
                  Management, Inc. (the "Management Agreement"), which
                  Management Agreement shall have a term of one year, be
                  terminable by Purchaser after six months without cause or
                  premium, have a management fee of five percent (5%), pay
                  standard leasing commissions and require Purchaser to pay
                  $300,000 to such manager for use exclusively as bonuses to
                  employees of such manager that are dedicated to property level
                  services including, without limitation, accounting and leasing
                  services, with no more than $150,000 of such bonuses being
                  paid prior to the date that is six months after the Closing,
                  provided, however, if Purchaser acquires less than all of the
                  properties under this Contract and the Dependent Contracts
                  pursuant to Section 14.1(f) hereof, then Purchaser shall be
                  entitled to reduce such $300,000 figure on a pro rata basis
                  based upon the purchase prices of the properties not acquired
                  under this Contract and the Dependent Contracts to the
                  aggregate purchase prices of all of the properties under this
                  Contract and the Dependent Contracts.

         (b)      Purchaser. At the Closing, Purchaser shall deliver to the
                  Title Company, for recording or delivery to Seller, as
                  applicable, each of the following items:

                           (i)  The Purchase Price in Current Funds.

                           (ii) The Assignment of Leases, duly executed and
                  acknowledged by Purchaser.

                           (iii) The Bill of Sale, duly executed by Purchaser.

                           (iv) Such additional funds in cash or Current Funds,
                  as may be necessary to cover Purchaser's share of the closing
                  costs and prorations hereunder.

                           (v) Evidence satisfactory to Seller and the Title
                  Company that the person or persons executing this Contract and
                  the closing documents on behalf of Purchaser have full right,
                  power and authority to do so.

                           (vi) The Notice Letters and Service Contract Notice
                  Letters duly executed by Purchaser.

                           (vii) Other items reasonably requested by the Title
                  Company for the sale of the Property in accordance with this
                  Contract or for administrative requirements for consummating
                  the Closing.

                           (viii) The Management Agreement executed by 
                  Purchaser.

                           (ix) The Assumption Agreement executed by Purchaser.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be
paid equally by Seller and Purchaser. Any and all costs relating to the Title
Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,
relating to (a) any financing obtained by the Purchaser for the purchase of the
Property (including, without limitation, any loan assumption fees and expenses
charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid
exclusively by Purchaser. All other expenses incurred by Seller and Purchaser
with respect to the Closing, including, but not limited to, the attorneys' fees
and costs and expenses incurred in connection with negotiating, preparing and
closing the transaction contemplated by this Contract, shall be borne and paid
exclusively by the party incurring same, unless otherwise expressly provided in
this Contract.

         8.4 Prorations. All normal and customarily proratable items, including,
without limitation, rents (including, without limitation, base rents, additional
rents, percentage rents and common area maintenance charges but excluding
Delinquent Rent [hereinafter defined] that is more than thirty (30) days past
due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for
any amounts paid by Seller attributable to the period on or after the Closing
Date) and Purchaser being responsible for, and credited or charged, as the case
may be, for all of same attributable to the period on and after the Closing
Date. All unapplied Deposits under Tenant Leases, if any, and all prepaid rents
paid by Tenants under Tenant Leases (but only to the extent such rents are for
periods from and after the Closing Date) shall be credited to Purchaser against
the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection


                                      -17-
<PAGE>



with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value
of the Property or for the tax rate) for the year of Closing are not available
at the Closing Date, the proration shall be made using figures from the
preceding year for the figures which are unavailable for the year of Closing.
All prorations hereunder shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new
Tenant Leases entered into by Seller after June 1, 1998 and prior to the Closing
Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.


                                      -18-
<PAGE>



                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,


                                      -19-
<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Two Hundred Sixteen Thousand and No/100
         Dollars ($216,000.00). Notwithstanding anything in Section 9.2(a) to
         the contrary, if


                                      -20-
<PAGE>



         Purchaser has not timely elected to terminate in accordance with
         Section 9.2(a), and if the proceeds payable with respect to the
         Property as a result of casualty exceed the Purchase Price for the
         Property, the portion of such proceeds in excess of the Purchase Price
         shall be paid to Seller (in addition to the Purchase Price) at the
         Closing. The foregoing provision shall survive the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)


                                      -22-
<PAGE>



after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and

         13.4 Parties Bound. Subject to the provisions of Section 13.5 hereof,
this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's

Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of
the Deed by Seller to Purchaser.

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation

of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are

that time is of the essence with respect to this Contract and Closing hereunder.

         13.11 Multiple Counterparts. This Contract may be executed in a number

counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part
thereof, by fire or any other casualty from the date this Contract is fully

         13.14 Business Days. All references to "business days" contained herein
are references to normal working business days, i.e., Monday through Friday of
each calendar week, exclusive of federal and national bank holidays. In the
event that any event hereunder is to occur, or a time period is to expire, on a
date which is not a business day, such event shall occur or such time period
shall expire on the next succeeding business day.

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which

such cooperation shall be without additional cost or liability. The provisions
of this Section 13.16 shall survive the Closing for a period of one year.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby


                                      -26-
<PAGE>



         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which


                                      -27-
<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Brandywine Place, Ltd. will remain
obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Brandywine
Place, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not


                                      -28-
<PAGE>



be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

                             SELLER:

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective
Date (hereinafter defined), Purchaser shall deliver to Chicago Title Insurance
Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), One Hundred
Thirty-Seven Thousand Five Hundred and No/100 Dollars ($137,500.00) (the
"Earnest Money Deposit") in cash or Current Funds, to be held by the Title
Company in escrow to be applied or disposed of by the Title Company as is
provided in this Contract. In the event Purchaser fails to deposit the Earnest
Money Deposit with the Title Company as herein provided, Seller may, at its
option, terminate this Contract, in which event neither Seller nor Purchaser
shall have any further obligations hereunder except for provisions of this
Contract which expressly survive the termination of this Contract. As used in
this Contract, the term "Current Funds" shall mean wire transfers, certified
funds or cashier's checks in a form acceptable to the Title Company which would
permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Seller shall, notwithstanding anything to the contrary contained
herein, satisfy all liens securing the payment of a monetary obligation and
affecting the Property at or prior to Closing, except for any liens or
encumbrances expressly permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion

                                       -3-


<PAGE>



but without any obligation to do so, any objection to the condition of title
raised by Purchaser. If Seller notifies Purchaser that it elects not to cure any
such objections, then Purchaser may, at its option exercisable within five (5)
days following the date of receipt by Purchaser of written notice from Seller
stating that Seller is unable or unwilling to cure such objections, either (a)
accept such title as Seller can deliver, in which case all exceptions to title
set forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (b) terminate this
Contract by notice in writing to Seller in which event the Title Company shall
return the Earnest Money Deposit to Purchaser and neither party shall have any
further rights, duties or obligations hereunder, except for provisions of this
Contract which expressly survive termination of this Contract. In the event
Purchaser fails to notify Seller, within such five (5) day period, that
Purchaser has elected to proceed under either subpart (a) or (b) of the
immediately preceding sentence, Purchaser shall be deemed to have elected to
proceed under subpart (a), and this Contract shall remain in full force and
effect. If Seller notifies Purchaser that it elects to cure any such objections
but is unable to cure same by Closing or if Seller fails to notify Purchaser of
its intentions with respect to such objections and fails to cure same by
Closing, then Purchaser may, at its option, either (x) accept such title as
Seller can deliver in which case the parties shall proceed with Closing and all
exceptions to title set forth in the Title Commitment, Exception Documents and
Survey which are not removed shall be deemed to be Permitted Exceptions, or (y)
terminate this Contract by notice in writing to Seller at Closing, in which
event the Title Company shall return the Earnest Money Deposit to Purchaser and
neither party shall have any further rights, duties or obligations hereunder
except for provisions of this Contract which expressly survive termination of
this Contract. If any additional exceptions to title other than those shown on
the initial Title Commitment or Survey arise between the date of the initial
Title Commitment, the Survey and the Closing (such exceptions to title being
referred to herein as the "New Exceptions"), Purchaser shall have five (5)
business days after its receipt of written notice of such New Exceptions within
which to notify Seller of any such New Exceptions to which Purchaser objects.
Any such New Exceptions not objected to by Purchaser as aforesaid shall become
"Permitted Exceptions" hereunder; provided, however, all New Exceptions created,
caused by, or consented to by Seller shall be satisfied or removed at Closing
and shall not constitute Permitted Exceptions unless such New Exceptions are
expressly permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any
such New Exceptions, Seller shall have until Closing to remove such New
Exceptions, which removal may be accomplished by waiver or endorsement by the
Title Company reasonably satisfactory to Purchaser. If Seller fails to remove
any such New Exceptions as aforesaid, Purchaser may, as its sole and exclusive
remedy, terminate this Contract and obtain a return of the Earnest Money Deposit
and neither party shall have any further rights, duties, or obligations
hereunder except for provisions of the Contract which expressly survive the
termination of this Contract. If Purchaser does not elect to terminate this
Agreement, Purchaser shall consummate the Closing and accept title to the
Property subject to all such New Exceptions (in which event, all such New
Exceptions, together with all other Permitted Exceptions, shall be deemed
"Permitted Exceptions" hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and

                                       -4-


<PAGE>



payable; (c) liens and encumbrances arising after the date hereof to which
Purchaser consents in writing; and (d) any liens or encumbrances of a definite
or ascertainable amount not exceeding $50,000.00 for the Property (and when such
amount is added to the aggregate amounts of any liens or encumbrances to be
insured and bonded around by the respective Dependent Sellers (hereinafter
defined) under the Dependent Contracts (hereinafter defined), such aggregate
amount shall not exceed $125,000.00), provided that (i) Seller causes such liens
or encumbrances to be insured or bonded around such that same do not appear as
an exception in the Title Policy issued to Purchaser pursuant to the Commitment,
and (ii) Seller agrees to indemnify Purchaser from all losses incurred by
Purchaser as a result of such liens or encumbrances.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding,

                                       -5-


<PAGE>



however, any proprietary development or marketing materials), (e) Purchaser
shall not permit any mechanic's or materialman's liens or any other liens to
attach to the Property by reason of the performance of any work or the purchase
of any materials by Purchaser or any other party on Purchaser's behalf in
connection with any studies or tests conducted pursuant to this Section 5.1, (f)
Purchaser shall give notice (which may be by telephone) to Seller a reasonable
time prior to entry onto the Property and shall permit Seller to have a
representative present during all investigations and inspections conducted with
respect to the Property, and (g) Purchaser shall take all reasonable actions and
implement all protections necessary to ensure that all actions taken in
connection with the investigations and inspections of the Property, and all
equipment, materials and substances generated, used or brought onto the Property
pose no material threat to the safety of persons or the environment and cause no
damage to the Property or other property of Seller or other persons. All
information made available by Seller to Purchaser in accordance with this
Contract or obtained by Purchaser in the course of its investigations shall be
treated as confidential information by Purchaser, and, prior to the purchase of
the Property by Purchaser, Purchaser shall use its best efforts to prevent its
agents and employees from divulging such information to any third parties except
(i) as reasonably necessary to third parties engaged by Purchaser for the
limited purpose of analyzing and investigating such information for the purpose
of consummating the transaction contemplated by this Contract, including
Purchaser's attorneys and representatives, prospective lenders and engineers or
(ii) as may required by applicable law, unless such information is generally
available to the public or is disclosed by a party other than Purchaser or its
agents. Purchaser shall indemnify, defend and hold Seller harmless for, from and
against any and all claims, liabilities, causes of action, damages, liens,
losses, costs and expenses (including, without limitation, reasonable attorneys'
fees) incident to, resulting from or in any way arising out of any of
Purchaser's and its agents', contractors' and representatives' activities on the
Property, including, without limitation, any tests or inspections conducted by
Purchaser or its agents, contractors or representatives on the Property. The
agreements contained in this Section 5.1 shall survive the Closing and not be
merged therein and shall also survive any termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service

                                       -6-

the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior to the Closing Date shall be deemed approved by Purchaser
and shall be assumed by Purchaser at Closing.

this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a)      The representations and warranties of Seller

         Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a)      the representations and warranties of Purchaser
         contained herein shall be true, accurate and correct as of the Closing

                                      -11-


<PAGE>



                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each Tenant complete, sign and deliver
such Estoppel Certificate to Seller. Seller's only obligation with respect to
such Estoppel Certificates shall be to request that each Tenant complete and
deliver to Seller such Estoppel Certificates. Purchaser's obligations to
consummate the transaction contemplated by this Contract are expressly subject
to and conditioned upon (x) Seller delivering to Purchaser on or before the
Closing Date Estoppel Certificates dated no earlier than thirty (30) days prior
to the Closing Date executed by Tenants occupying at least seventy percent (70%)
of the net rentable area of the Improvements, in the aggregate, and from all
Tenants set forth in Schedule 7.3 attached hereto and made a part hereof (the
"Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer

                                      -12-

have any liability hereunder with respect to the Seller's Certificate relating
to the Tenant Lease in question. The provisions of this Section shall survive
the Closing and delivery of the Deed.

connection with any such financing shall be borne and paid exclusively by
Purchaser. All other expenses incurred by Seller and Purchaser with respect to
the Closing, including, but not limited to, the attorneys' fees and costs and

request shall be accompanied by a copy of the Tenant Lease in question and the

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property

Seller has notified Tenants in writing that estimated additional rent payments
(the "1998 Additional Rent Payments") are required to be paid by the Tenants at
such time as base rent payments are due and payable during the balance of the
1998 calendar year. Purchaser agrees that at such time as the 1998 Additional
Rent Payments are received from the Tenants after the Closing Date, Purchaser
shall promptly deliver Seller's Pro rata Portion of such 1998 Additional Rent
Payments to Seller. As used in this Section 8.8, Seller's Pro rata Portion shall
be equal to the amount expressed in percentage terms determined by dividing (x)
the number of days that Seller owned the Property in the 1998 calendar year by
(y) 365. The provisions of this Section 8.8 shall survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1 Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights, duties, or obligations hereunder except
         for provisions of this Contract which expressly survive the termination
         of this Contract. If Purchaser does not terminate this Contract as
         aforesaid or the taking is not substantial, then both parties shall
         proceed to close the transaction contemplated herein pursuant to the
         terms hereof, in which event Seller shall, except as limited in Section
         9.1(b) hereof, deliver to Purchaser at the Closing any proceeds
         actually received by Seller attributable to the Property from such
         condemnation, eminent domain proceeding or deed in lieu thereof and
         assign its interest in and to the balance of any unpaid proceeds, and
         there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                      -18-

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Sixty-Seven Thousand Two
         Hundred and No/100 Dollars ($167,200.00). Notwithstanding anything in
         Section 9.2(a) to the contrary, if Purchaser has not timely elected to
         terminate in accordance with Section 9.2(a), and if the proceeds
         payable with respect to the Property as a result of casualty exceed the
         Purchase Price for the Property, the portion of such proceeds in excess
         of the Purchase Price shall be paid to Seller (in addition to the
         Purchase Price) at the Closing. The foregoing provision shall survive
         the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by

                                      -19-


<PAGE>



Purchaser of any indemnity under this Contract which survives the Closing or
termination of this Contract, Seller shall have any and all rights and remedies
available at law or in equity by reason of such default, excluding, however, any
punitive, speculative or consequential damages or damages for loss of
opportunity or lost profit. Except as otherwise provided in this Section 10.1,
in no event shall Purchaser be liable to Seller for any damages, including,
without limitation, any actual, punitive, speculative or consequential damages
or damages for loss of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost

                                      -20-


<PAGE>



or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Purchaser by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Seller (including, without limitation, Broker). Purchaser
agrees to indemnify Seller and hold Seller harmless from any loss, liability,
damage, cost or expense (including, without limitation, reasonable attorneys'
fees) arising out of or paid or incurred by Seller by reason of any claim to any
broker's, finder's or other fee in connection with this transaction by any party
claiming by, through or under Purchaser (excluding Broker). Notwithstanding
anything to the contrary contained herein, the indemnities and other provisions
set forth in this Article XI shall survive the Closing or termination of this
Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii) after June 1, 1998, Seller shall
not materially modify or terminate any existing Tenant Lease or grant any
material consents under any existing Tenant Lease (except as otherwise required
pursuant to the terms and conditions of such Tenant Lease), or enter into any
new Tenant Lease, and (iii) Seller shall not apply any then unapplied Deposits
(as reflected on the Rent Roll delivered by Seller to Purchaser pursuant to
Schedule 5.3(vii) hereof) under Tenant Leases); and (b) advise Purchaser of the
commencement of any litigation, condemnation or other judicial or administrative
proceedings affecting the Property of which Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby agrees, for a period of six months after Closing,
         to permit Purchaser and Purchaser's accountants access to such books
         and records (including those maintained by Seller's management agent
         for the Property) and to cooperate with Purchaser, and to cause
         Seller's accountants to cooperate with Purchaser, at no cost to Seller,
         to enable such audit to be performed. The provisions of this Section
         13.17(b) shall survive the Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition

                                      -25-


<PAGE>



         of the properties set forth and described in the Dependent Contracts 
         pursuant to the terms and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which entitles Seller to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract shall be promptly paid to Seller and
         the earnest money deposits held under the Dependent Contracts shall be
         promptly paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

                                      -26-


<PAGE>



         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Forest Abrams Place, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Forest
Abrams Place, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not be released from any representations,
warranties, covenants, agreements or obligations hereunder as a result of the
exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

                                CONTRACT OF SALE
                   [Sherman Tech Building, Richardson, Texas]


         THIS CONTRACT OF SALE (this "Contract") is made and entered into by and
between SHERMAN TECH PARTNERS, a Texas limited partnership ("Seller") and BEACON

                                   ARTICLE I.

                              SALE OF THE PROPERTY

         1.1 Property. For the consideration and upon and subject to the terms,

         County, Texas, more particularly described on Exhibit A attached hereto
         and made a part hereof for all purposes, together with all
         improvements, structures and fixtures, if any, located on the Land (the
         "Improvements"), and all rights, titles and interests of Seller
         appurtenant to the Land and Improvements, including, without
         limitation, appurtenant easements, adjacent roads, highways and
         rights-of-way;

                  (b) All tangible and intangible personal property of any kind
         (the "Personalty") owned by Seller and attached to or located on or
         used in connection with the Land or Improvements including, without
         limitation, those items of tangible personal property set forth on the

         tenants ("Tenants") under the Tenant Leases and all of Seller's rights,
         titles and interests in and to all leasing commission agreements (the
         "Commission Agreements") relating to the Tenant Leases that Purchaser
         is required to assume as contemplated by Section 5.2 hereof ; and

                  (d) All of Seller's rights, titles and interests in and to all

                                   ARTICLE II.

                                 PURCHASE PRICE

         2.1 Purchase Price. The total Purchase Price (herein so called) to be
paid by Purchaser to Seller for the Property shall be an amount equal to Seven
Hundred Ten Thousand and No/100 Dollars ($710,000.00). The Purchase Price shall
be payable in cash or Current Funds (hereinafter defined) at Closing.

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective
Date (hereinafter defined), Purchaser shall deliver to Chicago Title Insurance
Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), Twenty-Three Thousand
Three Hundred Fifty-Five and No/100 Dollars ($23,355.00) (the "Earnest Money
Deposit") in cash or Current Funds, to be held by the Title Company in escrow to
be applied or disposed of by the Title Company as is provided in this Contract.
In the event Purchaser fails to deposit the Earnest Money Deposit with the Title
Company as herein provided, Seller may, at its option, terminate this Contract,
in which event neither Seller nor Purchaser shall have any further obligations
hereunder except for provisions of this Contract which expressly survive the
termination of this Contract. As used in this Contract, the term "Current Funds"
shall mean wire transfers, certified funds or cashier's checks in a form
acceptable to the Title Company which would permit the Title Company to
immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Seller shall, notwithstanding anything to the contrary contained
herein, satisfy all liens securing the payment of a monetary obligation and
affecting the Property at or prior to Closing, except for any liens or
encumbrances expressly permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion

                                       -3-


<PAGE>



but without any obligation to do so, any objection to the condition of title
raised by Purchaser. If Seller notifies Purchaser that it elects not to cure any
such objections, then Purchaser may, at its option exercisable within five (5)
days following the date of receipt by Purchaser of written notice from Seller
stating that Seller is unable or unwilling to cure such objections, either (a)
accept such title as Seller can deliver, in which case all exceptions to title
set forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (b) terminate this
Contract by notice in writing to Seller in which event the Title Company shall
return the Earnest Money Deposit to Purchaser and neither party shall have any
further rights, duties or obligations hereunder, except for provisions of this
Contract which expressly survive termination of this Contract. In the event
Purchaser fails to notify Seller, within such five (5) day period, that
Purchaser has elected to proceed under either subpart (a) or (b) of the
immediately preceding sentence, Purchaser shall be deemed to have elected to
proceed under subpart (a), and this Contract shall remain in full force and
effect. If Seller notifies Purchaser that it elects to cure any such objections
but is unable to cure same by Closing or if Seller fails to notify Purchaser of
its intentions with respect to such objections and fails to cure same by
Closing, then Purchaser may, at its option, either (x) accept such title as
Seller can deliver in which case the parties shall proceed with Closing and all
exceptions to title set forth in the Title Commitment, Exception Documents and
Survey which are not removed shall be deemed to be Permitted Exceptions, or (y)
terminate this Contract by notice in writing to Seller at Closing, in which
event the Title Company shall return the Earnest Money Deposit to Purchaser and
neither party shall have any further rights, duties or obligations hereunder
except for provisions of this Contract which expressly survive termination of
this Contract. If any additional exceptions to title other than those shown on
the initial Title Commitment or Survey arise between the date of the initial
Title Commitment, the Survey and the Closing (such exceptions to title being
referred to herein as the "New Exceptions"), Purchaser shall have five (5)
business days after its receipt of written notice of such New Exceptions within
which to notify Seller of any such New Exceptions to which Purchaser objects.
Any such New Exceptions not objected to by Purchaser as aforesaid shall become
"Permitted Exceptions" hereunder; provided, however, all New Exceptions created,
caused by, or consented to by Seller shall be satisfied or removed at Closing
and shall not constitute Permitted Exceptions unless such New Exceptions are
expressly permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any
such New Exceptions, Seller shall have until Closing to remove such New
Exceptions, which removal may be accomplished by waiver or endorsement by the
Title Company reasonably satisfactory to Purchaser. If Seller fails to remove
any such New Exceptions as aforesaid, Purchaser may, as its sole and exclusive
remedy, terminate this Contract and obtain a return of the Earnest Money Deposit
and neither party shall have any further rights, duties, or obligations
hereunder except for provisions of the Contract which expressly survive the
termination of this Contract. If Purchaser does not elect to terminate this
Agreement, Purchaser shall consummate the Closing and accept title to the
Property subject to all such New Exceptions (in which event, all such New
Exceptions, together with all other Permitted Exceptions, shall be deemed
"Permitted Exceptions" hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and

                                       -4-


<PAGE>



payable; (c) liens and encumbrances arising after the date hereof to which
Purchaser consents in writing; and (d) any liens or encumbrances of a definite
or ascertainable amount not exceeding $50,000.00 for the Property (and when such
amount is added to the aggregate amounts of any liens or encumbrances to be
insured and bonded around by the respective Dependent Sellers (hereinafter
defined) under the Dependent Contracts (hereinafter defined), such aggregate
amount shall not exceed $125,000.00), provided that (i) Seller causes such liens
or encumbrances to be insured or bonded around such that same do not appear as
an exception in the Title Policy issued to Purchaser pursuant to the Commitment,
and (ii) Seller agrees to indemnify Purchaser from all losses incurred by
Purchaser as a result of such liens or encumbrances.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding,

                                       -5-


<PAGE>



however, any proprietary development or marketing materials), (e) Purchaser
shall not permit any mechanic's or materialman's liens or any other liens to
attach to the Property by reason of the performance of any work or the purchase
of any materials by Purchaser or any other party on Purchaser's behalf in
connection with any studies or tests conducted pursuant to this Section 5.1, (f)
Purchaser shall give notice (which may be by telephone) to Seller a reasonable
time prior to entry onto the Property and shall permit Seller to have a
representative present during all investigations and inspections conducted with
respect to the Property, and (g) Purchaser shall take all reasonable actions and
implement all protections necessary to ensure that all actions taken in
connection with the investigations and inspections of the Property, and all
equipment, materials and substances generated, used or brought onto the Property
pose no material threat to the safety of persons or the environment and cause no
damage to the Property or other property of Seller or other persons. All
information made available by Seller to Purchaser in accordance with this
Contract or obtained by Purchaser in the course of its investigations shall be
treated as confidential information by Purchaser, and, prior to the purchase of
the Property by Purchaser, Purchaser shall use its best efforts to prevent its
agents and employees from divulging such information to any third parties except
(i) as reasonably necessary to third parties engaged by Purchaser for the
limited purpose of analyzing and investigating such information for the purpose
of consummating the transaction contemplated by this Contract, including
Purchaser's attorneys and representatives, prospective lenders and engineers or
(ii) as may required by applicable law, unless such information is generally
available to the public or is disclosed by a party other than Purchaser or its
agents. Purchaser shall indemnify, defend and hold Seller harmless for, from and
against any and all claims, liabilities, causes of action, damages, liens,
losses, costs and expenses (including, without limitation, reasonable attorneys'
fees) incident to, resulting from or in any way arising out of any of
Purchaser's and its agents', contractors' and representatives' activities on the
Property, including, without limitation, any tests or inspections conducted by
Purchaser or its agents, contractors or representatives on the Property. The
agreements contained in this Section 5.1 shall survive the Closing and not be
merged therein and shall also survive any termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service

of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such

Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior to the Closing Date shall be deemed approved by Purchaser
and shall be assumed by Purchaser at Closing.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and


                                      -11-


<PAGE>



                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each Tenant complete, sign and deliver
such Estoppel Certificate to Seller. Seller's only obligation with respect to
such Estoppel Certificates shall be to request that each Tenant complete and
deliver to Seller such Estoppel Certificates. Purchaser's obligations to
consummate the transaction contemplated by this Contract are expressly subject
to and conditioned upon (x) Seller delivering to Purchaser on or before the
Closing Date Estoppel Certificates dated no earlier than thirty (30) days prior
to the Closing Date, executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer

                                      -12-

have any liability hereunder with respect to the Seller's Certificate relating
to the Tenant Lease in question. The provisions of this Section shall survive
the Closing and delivery of the Deed.

Property (the "Closing") shall take place at the office of the Title Company (it

earlier date and time as Purchaser and Seller may mutually agree (the "Closing

         8.2      Items to be Delivered at the Closing.

                  (a) Seller. At the Closing, Seller shall deliver, or cause to

                  Title Company for the benefit of and at the expense of
                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                  encumbrances except for the Permitted Exceptions.

                           (iii) An Assignment and Assumption of Leases and

                  returns required under Internal Revenue Code Section 6045.

                           (xvi) Keys to all locks at the Property.

                           (xvii) Evidence that Broker (hereinafter defined) has

                           (xviii) A management agreement for the Property and

                  shall have a term of one year, be terminable by Purchaser
                  after six months without cause or premium, have a management
                  fee of five percent (5%), pay standard leasing commissions and
                  require Purchaser to pay $300,000 to such manager for use
                  exclusively as bonuses to employees of such manager that are
                  dedicated to property level services including, without
                  limitation, accounting and leasing services, with no more than
                  $150,000 of such bonuses being paid prior to the date that is
                  six months after the Closing, provided, however, if Purchaser
                  acquires less than all of the properties under this Contract
                  and the Dependent Contracts pursuant to Section 14.1(f)
                  hereof, then Purchaser shall be entitled to reduce such
                  $300,000 figure on a pro rata basis based upon the purchase
                  prices of the properties not acquired under this Contract and
                  the Dependent Contracts to the aggregate purchase prices of
                  all of the properties under this Contract and the Dependent
                  Contracts.

         (b)      Purchaser. At the Closing, Purchaser shall deliver to the
                  Title Company, for recording or delivery to Seller, as
                  applicable, each of the following items:

                           (i)  The Purchase Price in Current Funds.

                           (ii) The Assignment of Leases, duly executed and
                  acknowledged by Purchaser.

                           (iii) The Bill of Sale, duly executed by Purchaser.

                           (iv) Such additional funds in cash or Current Funds,
                  as may be necessary to cover Purchaser's share of the closing

                           (v) Evidence satisfactory to Seller and the Title
                  Company that the person or persons executing this Contract and
                  the closing documents on behalf of Purchaser have full right,
                  power and authority to do so.

                           (vi) The Notice Letters and Service Contract Notice
                  Letters duly executed by Purchaser.

                           (vii) Other items reasonably requested by the Title
                  Company for the sale of the Property in accordance with this
                  Contract or for administrative requirements for consummating
                  the Closing.

                           (viii) The Management Agreement executed by
                  Purchaser.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be
paid equally by Seller and Purchaser. Any and all costs relating to the Title
Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,

Property, and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes,

                                      -15-


<PAGE>



mortgage taxes or other similar taxes, fees or assessments incurred in
connection with any such financing shall be borne and paid exclusively by
Purchaser. All other expenses incurred by Seller and Purchaser with respect to
the Closing, including, but not limited to, the attorneys' fees and costs and
expenses incurred in connection with negotiating, preparing and closing the
transaction contemplated by this Contract, shall be borne and paid exclusively
by the party incurring same, unless otherwise expressly provided in this
Contract.

         8.4 Prorations. All normal and customarily proratable items, including,
without limitation, rents (including, without limitation, base rents, additional
rents, percentage rents and common area maintenance charges but excluding
Delinquent Rent [hereinafter defined] that is more than thirty (30) days past
due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for
any amounts paid by Seller attributable to the period on or after the Closing
Date) and Purchaser being responsible for, and credited or charged, as the case
may be, for all of same attributable to the period on and after the Closing
Date. All unapplied Deposits under Tenant Leases, if any, and all prepaid rents
paid by Tenants under Tenant Leases (but only to the extent such rents are for
periods from and after the Closing Date) shall be credited to Purchaser against
the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection with the
proration of real property taxes or installments of assessments, such proration
shall be based upon the assessed valuation and tax rate figures for the year in
which the Closing occurs to the extent the same are available; provided, that in
the event that actual figures (whether for the assessed value of the Property or
for the tax rate) for the year of Closing are not available at the Closing Date,
the proration shall be made using figures from the preceding year for the
figures which are unavailable for the year of Closing. All prorations hereunder
shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new
Tenant Leases entered into by Seller after June 1, 1998 and prior to the Closing
Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

<PAGE>



         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998,

                                      -17-


<PAGE>



Seller has notified Tenants in writing that estimated additional rent payments
(the "1998 Additional Rent Payments") are required to be paid by the Tenants at
such time as base rent payments are due and payable during the balance of the
1998 calendar year. Purchaser agrees that at such time as the 1998 Additional
Rent Payments are received from the Tenants after the Closing Date, Purchaser
shall promptly deliver Seller's Pro rata Portion of such 1998 Additional Rent
Payments to Seller. As used in this Section 8.8, Seller's Pro rata Portion shall
be equal to the amount expressed in percentage terms determined by dividing (x)
the number of days that Seller owned the Property in the 1998 calendar year by
(y) 365. The provisions of this Section 8.8 shall survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights, duties, or obligations hereunder except
         for provisions of this Contract which expressly survive the termination
         of this Contract. If Purchaser does not terminate this Contract as
         aforesaid or the taking is not substantial, then both parties shall
         proceed to close the transaction contemplated herein pursuant to the
         terms hereof, in which event Seller shall, except as limited in Section
         9.1(b) hereof, deliver to Purchaser at the Closing any proceeds
         actually received by Seller attributable to the Property from such
         condemnation, eminent domain proceeding or deed in lieu thereof and
         assign its interest in and to the balance of any unpaid proceeds, and
         there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Twenty-Eight Thousand Four Hundred and
         No/100 Dollars ($28,400.00). Notwithstanding anything in Section 9.2(a)
         to the contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by

                                      -19-


<PAGE>



Purchaser of any indemnity under this Contract which survives the Closing or
termination of this Contract, Seller shall have any and all rights and remedies
available at law or in equity by reason of such default, excluding, however, any
punitive, speculative or consequential damages or damages for loss of
opportunity or lost profit. Except as otherwise provided in this Section 10.1,
in no event shall Purchaser be liable to Seller for any damages, including,
without limitation, any actual, punitive, speculative or consequential damages
or damages for loss of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost

                                      -20-


<PAGE>



or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Purchaser by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Seller (including, without limitation, Broker). Purchaser
agrees to indemnify Seller and hold Seller harmless from any loss, liability,
damage, cost or expense (including, without limitation, reasonable attorneys'
fees) arising out of or paid or incurred by Seller by reason of any claim to any
broker's, finder's or other fee in connection with this transaction by any party
claiming by, through or under Purchaser (excluding Broker). Notwithstanding
anything to the contrary contained herein, the indemnities and other provisions
set forth in this Article XI shall survive the Closing or termination of this
Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii) after June 1, 1998, Seller shall
not materially modify or terminate any existing Tenant Lease or grant any
material consents under any existing Tenant Lease (except as otherwise required
pursuant to the terms and conditions of such Tenant Lease), or enter into any
new Tenant Lease, and (iii) Seller shall not apply any then unapplied Deposits
(as reflected on the Rent Roll delivered by Seller to Purchaser pursuant to
Schedule 5.3(vii) hereof) under Tenant Leases); and (b) advise Purchaser of the
commencement of any litigation, condemnation or other judicial or administrative
proceedings affecting the Property of which Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in

         13.2 GOVERNING LAW; VENUE. THIS CONTRACT IS BEING EXECUTED AND
DELIVERED, AND IS INTENDED TO BE PERFORMED IN, THE STATE OF TEXAS, AND THE LAWS
OF SUCH STATE SHALL GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND
INTERPRETATION OF THIS CONTRACT AND IN THE EVENT OF A DISPUTE INVOLVING THIS
CONTRACT OR ANY DOCUMENTS EXECUTED IN CONNECTION HEREWITH, PURCHASER IRREVOCABLY
AGREES THAT VENUE FOR SUCH DISPUTE SHALL LIE IN ANY COURT OF COMPETENT
JURISDICTION IN DALLAS COUNTY, TEXAS.

         13.3 Entirety and Amendments. This Contract embodies the entire
agreement between the parties and supersedes all prior agreements and
understandings, if any, relating to the transaction described herein, and may be
amended or supplemented only by an instrument in writing executed by the party
against whom enforcement is sought.

         13.4 Parties Bound. Subject to the provisions of Section 13.5 hereof,
this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's
option, be null and void and of no effect. In the event of an assignment of this
Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of
the Deed by Seller to Purchaser.

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof,

                                      -23-


<PAGE>



and this Contract shall be construed as if such invalid, illegal or
unenforceable provisions had never been contained herein. When the context in
which words are used in this Contract indicates that such is the intent, words
in the singular number shall include the plural and vice versa, and words in the
masculine gender shall include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are
references to exhibits attached hereto, all of which are hereby made a part
hereof for all purposes.

         13.10 Time of Essence. It is expressly agreed by the parties hereto
that time is of the essence with respect to this Contract and Closing hereunder.

         13.11 Multiple Counterparts. This Contract may be executed in a number
of identical counterparts. If so executed, each of such counterparts is to be
deemed an original for all purposes, and all such counterparts shall,
collectively, constitute one agreement, but, in making proof of this Contract,
it shall not be necessary to produce or account for more than one such
counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part
thereof, by fire or any other casualty from the date this Contract is fully
executed up to the time of delivering the Deed transferring title to the
Property to the Purchaser will be on the Seller and, thereafter, will be on the
Purchaser.

         13.13 Effective Date. As used herein, the term "Effective Date" shall
mean for all purposes in this Contract the date on which the Title Company
acknowledges receipt of an original of the Contract executed by Purchaser and
Seller with all changes, if any, to the printed portion of this Contract
initialed by Purchaser and Seller.

         13.14 Business Days. All references to "business days" contained herein
are references to normal working business days, i.e., Monday through Friday of
each calendar week, exclusive of federal and national bank holidays. In the
event that any event hereunder is to occur, or a time period is to expire, on a
date which is not a business day, such event shall occur or such time period
shall expire on the next succeeding business day.

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which
the Property is situated, and any such recordation or attempted recordation
shall constitute a breach of this Contract by the party responsible for such
recordation or attempted recordation.

         13.16 Post-Closing Obligations. After the Closing, Seller and Purchaser
shall cooperate with one another at reasonable times and on reasonable
conditions and shall execute and deliver such instruments and documents as may
be necessary in order fully to carry out the intent and purposes of the
transactions contemplated hereby. Except for such instruments and documents as
the parties were originally obligated to deliver by the terms of this Contract,

         13.17    Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby agrees, for a period of six months after Closing,
         to permit Purchaser and Purchaser's accountants access to such books
         and records (including those maintained by Seller's management agent
         for the Property) and to cooperate with Purchaser, and to cause
         Seller's accountants to cooperate with Purchaser, at no cost to Seller,
         to enable such audit to be performed. The provisions of this Section
         13.17(b) shall survive the Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition

                                      -25-


<PAGE>



         of the properties set forth and described in the Dependent Contracts
         pursuant to the terms and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which entitles Seller to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract shall be promptly paid to Seller and
         the earnest money deposits held under the Dependent Contracts shall be
         promptly paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.


                                      -26-


<PAGE>



         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Sherman Tech Partners will remain
obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Sherman
Tech Partners.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not be released from any representations,
warranties, covenants, agreements or obligations hereunder as a result of the
exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         2.1 Purchase Price. The total Purchase Price (herein so called) to be
paid by Purchaser to Seller for the Property shall be an amount equal to Four

                                  ARTICLE III.

                EARNEST MONEY; INDEPENDENT CONTRACT CONSIDERATION

         3.1 Amount and Timing. Within two (2) business days after the Effective
Date (hereinafter defined), Purchaser shall deliver to Chicago Title Insurance
Company, located at 8117 Preston Road, Suite 100, Dallas, Texas 75225,
Attention: J. David Griffin, Esq. (the "Title Company"), One Hundred Forty-Four
Thousand Seventy-Nine and No/100 Dollars ($144,079.00) (the "Earnest Money
Deposit") in cash or Current Funds, to be held by the Title Company in escrow to
be applied or disposed of by the Title Company as is provided in this Contract.
In the event Purchaser fails to deposit the Earnest Money Deposit with the Title
Company as herein provided, Seller may, at its option, terminate this Contract,
in which event neither Seller nor Purchaser shall have any further obligations
hereunder except for provisions of this Contract which expressly survive the
termination of this Contract. As used in this Contract, the term "Current Funds"
shall mean wire transfers, certified funds or cashier's checks in a form
acceptable to the Title Company which would permit the Title Company to
immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Seller shall, notwithstanding anything to the contrary contained
herein, satisfy all liens securing the payment of a monetary obligation and
affecting the Property at or prior to Closing, except for any liens or
encumbrances expressly permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion


                                       -3-


<PAGE>



but without any obligation to do so, any objection to the condition of title
raised by Purchaser. If Seller notifies Purchaser that it elects not to cure any
such objections, then Purchaser may, at its option exercisable within five (5)
days following the date of receipt by Purchaser of written notice from Seller
stating that Seller is unable or unwilling to cure such objections, either (a)
accept such title as Seller can deliver, in which case all exceptions to title
set forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (b) terminate this
Contract by notice in writing to Seller in which event the Title Company shall
return the Earnest Money Deposit to Purchaser and neither party shall have any
further rights, duties or obligations hereunder, except for provisions of this
Contract which expressly survive termination of this Contract. In the event
Purchaser fails to notify Seller, within such five (5) day period, that
Purchaser has elected to proceed under either subpart (a) or (b) of the
immediately preceding sentence, Purchaser shall be deemed to have elected to
proceed under subpart (a), and this Contract shall remain in full force and
effect. If Seller notifies Purchaser that it elects to cure any such objections
but is unable to cure same by Closing or if Seller fails to notify Purchaser of
its intentions with respect to such objections and fails to cure same by
Closing, then Purchaser may, at its option, either (x) accept such title as
Seller can deliver in which case the parties shall proceed with Closing and all
exceptions to title set forth in the Title Commitment, Exception Documents and
Survey which are not removed shall be deemed to be Permitted Exceptions, or (y)
terminate this Contract by notice in writing to Seller at Closing, in which
event the Title Company shall return the Earnest Money Deposit to Purchaser and
neither party shall have any further rights, duties or obligations hereunder
except for provisions of this Contract which expressly survive termination of
this Contract. If any additional exceptions to title other than those shown on
the initial Title Commitment or Survey arise between the date of the initial
Title Commitment, the Survey and the Closing (such exceptions to title being
referred to herein as the "New Exceptions"), Purchaser shall have five (5)
business days after its receipt of written notice of such New Exceptions within
which to notify Seller of any such New Exceptions to which Purchaser objects.
Any such New Exceptions not objected to by Purchaser as aforesaid shall become
"Permitted Exceptions" hereunder; provided, however, all New Exceptions created,
caused by, or consented to by Seller shall be satisfied or removed at Closing
and shall not constitute Permitted Exceptions unless such New Exceptions are
expressly permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any
such New Exceptions, Seller shall have until Closing to remove such New
Exceptions, which removal may be accomplished by waiver or endorsement by the
Title Company reasonably satisfactory to Purchaser. If Seller fails to remove
any such New Exceptions as aforesaid, Purchaser may, as its sole and exclusive
remedy, terminate this Contract and obtain a return of the Earnest Money Deposit
and neither party shall have any further rights, duties, or obligations
hereunder except for provisions of the Contract which expressly survive the
termination of this Contract. If Purchaser does not elect to terminate this
Agreement, Purchaser shall consummate the Closing and accept title to the
Property subject to all such New Exceptions (in which event, all such New
Exceptions, together with all other Permitted Exceptions, shall be deemed
"Permitted Exceptions" hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and


                                       -4-


<PAGE>



payable; (c) liens and encumbrances arising after the date hereof to which
Purchaser consents in writing; and (d) any liens or encumbrances of a definite
or ascertainable amount not exceeding $50,000.00 for the Property (and when such
amount is added to the aggregate amounts of any liens or encumbrances to be
insured and bonded around by the respective Dependent Sellers (hereinafter
defined) under the Dependent Contracts (hereinafter defined), such aggregate
amount shall not exceed $125,000.00), provided that (i) Seller causes such liens
or encumbrances to be insured or bonded around such that same do not appear as
an exception in the Title Policy issued to Purchaser pursuant to the Commitment,
and (ii) Seller agrees to indemnify Purchaser from all losses incurred by
Purchaser as a result of such liens or encumbrances.

                                   ARTICLE V.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding,


                                       -5-


<PAGE>



however, any proprietary development or marketing materials), (e) Purchaser
shall not permit any mechanic's or materialman's liens or any other liens to
attach to the Property by reason of the performance of any work or the purchase
of any materials by Purchaser or any other party on Purchaser's behalf in
connection with any studies or tests conducted pursuant to this Section 5.1, (f)
Purchaser shall give notice (which may be by telephone) to Seller a reasonable
time prior to entry onto the Property and shall permit Seller to have a
representative present during all investigations and inspections conducted with
respect to the Property, and (g) Purchaser shall take all reasonable actions and
implement all protections necessary to ensure that all actions taken in
connection with the investigations and inspections of the Property, and all
equipment, materials and substances generated, used or brought onto the Property
pose no material threat to the safety of persons or the environment and cause no
damage to the Property or other property of Seller or other persons. All
information made available by Seller to Purchaser in accordance with this
Contract or obtained by Purchaser in the course of its investigations shall be
treated as confidential information by Purchaser, and, prior to the purchase of
the Property by Purchaser, Purchaser shall use its best efforts to prevent its
agents and employees from divulging such information to any third parties except
(i) as reasonably necessary to third parties engaged by Purchaser for the
limited purpose of analyzing and investigating such information for the purpose
of consummating the transaction contemplated by this Contract, including
Purchaser's attorneys and representatives, prospective lenders and engineers or
(ii) as may required by applicable law, unless such information is generally
available to the public or is disclosed by a party other than Purchaser or its
agents. Purchaser shall indemnify, defend and hold Seller harmless for, from and
against any and all claims, liabilities, causes of action, damages, liens,
losses, costs and expenses (including, without limitation, reasonable attorneys'
fees) incident to, resulting from or in any way arising out of any of
Purchaser's and its agents', contractors' and representatives' activities on the
Property, including, without limitation, any tests or inspections conducted by
Purchaser or its agents, contractors or representatives on the Property. The
agreements contained in this Section 5.1 shall survive the Closing and not be
merged therein and shall also survive any termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service


                                       -6-

the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior to the Closing Date shall be deemed approved by Purchaser
and shall be assumed by Purchaser at Closing.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and


                                      -11-


<PAGE>



                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each Tenant complete, sign and deliver
such Estoppel Certificate to Seller. Seller's only obligation with respect to
such Estoppel Certificates shall be to request that each Tenant complete and
deliver to Seller such Estoppel Certificates. Purchaser's obligations to
consummate the transaction contemplated by this Contract are expressly subject
to and conditioned upon (x) Seller delivering to Purchaser on or before the
Closing Date Estoppel Certificates dated no earlier than thirty (30) days prior
to the Closing Date, executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer


                                      -12-


<PAGE>



have any liability hereunder with respect to the Seller's Certificate relating
to the Tenant Lease in question. The provisions of this Section shall survive
the Closing and delivery of the Deed.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be

Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,

Property, and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,

mortgage taxes or other similar taxes, fees or assessments incurred in
connection with any such financing shall be borne and paid exclusively by
Purchaser. All other expenses incurred by Seller and Purchaser with respect to
the Closing, including, but not limited to, the attorneys' fees and costs and
expenses incurred in connection with negotiating, preparing and closing the

         8.4 Prorations. All normal and customarily proratable items, including,

due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for

the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection with the
proration of real property taxes or installments of assessments, such proration
shall be based upon the assessed valuation and tax rate figures for the year in
which the Closing occurs to the extent the same are available; provided, that in
the event that actual figures (whether for the assessed value of the Property or
for the tax rate) for the year of Closing are not available at the Closing Date,

Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property

provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998,


                                      -17-

Seller has notified Tenants in writing that estimated additional rent payments
(the "1998 Additional Rent Payments") are required to be paid by the Tenants at
such time as base rent payments are due and payable during the balance of the
1998 calendar year. Purchaser agrees that at such time as the 1998 Additional
Rent Payments are received from the Tenants after the Closing Date, Purchaser
shall promptly deliver Seller's Pro rata Portion of such 1998 Additional Rent
Payments to Seller. As used in this Section 8.8, Seller's Pro rata Portion shall
be equal to the amount expressed in percentage terms determined by dividing (x)
the number of days that Seller owned the Property in the 1998 calendar year by
(y) 365. The provisions of this Section 8.8 shall survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights, duties, or obligations hereunder except
         for provisions of this Contract which expressly survive the termination
         of this Contract. If Purchaser does not terminate this Contract as
         aforesaid or the taking is not substantial, then both parties shall
         proceed to close the transaction contemplated herein pursuant to the
         terms hereof, in which event Seller shall, except as limited in Section
         9.1(b) hereof, deliver to Purchaser at the Closing any proceeds
         actually received by Seller attributable to the Property from such
         condemnation, eminent domain proceeding or deed in lieu thereof and
         assign its interest in and to the balance of any unpaid proceeds, and
         there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Seventy-Five Thousand Two
         Hundred and No/100 Dollars ($175,200.00). Notwithstanding anything in
         Section 9.2(a) to the contrary, if Purchaser has not timely elected to
         terminate in accordance with Section 9.2(a), and if the proceeds
         payable with respect to the Property as a result of casualty exceed the
         Purchase Price for the Property, the portion of such proceeds in excess
         of the Purchase Price shall be paid to Seller (in addition to the
         Purchase Price) at the Closing. The foregoing provision shall survive
         the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by


                                      -19-


<PAGE>



Purchaser of any indemnity under this Contract which survives the Closing or
termination of this Contract, Seller shall have any and all rights and remedies
available at law or in equity by reason of such default, excluding, however, any
punitive, speculative or consequential damages or damages for loss of
opportunity or lost profit. Except as otherwise provided in this Section 10.1,
in no event shall Purchaser be liable to Seller for any damages, including,
without limitation, any actual, punitive, speculative or consequential damages
or damages for loss of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost


                                      -20-


<PAGE>



or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Purchaser by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Seller (including, without limitation, Broker). Purchaser
agrees to indemnify Seller and hold Seller harmless from any loss, liability,
damage, cost or expense (including, without limitation, reasonable attorneys'
fees) arising out of or paid or incurred by Seller by reason of any claim to any
broker's, finder's or other fee in connection with this transaction by any party
claiming by, through or under Purchaser (excluding Broker). Notwithstanding
anything to the contrary contained herein, the indemnities and other provisions
set forth in this Article XI shall survive the Closing or termination of this
Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii) after June 1, 1998, Seller shall
not materially modify or terminate any existing Tenant Lease or grant any
material consents under any existing Tenant Lease (except as otherwise required
pursuant to the terms and conditions of such Tenant Lease), or enter into any
new Tenant Lease, and (iii) Seller shall not apply any then unapplied Deposits
(as reflected on the Rent Roll delivered by Seller to Purchaser pursuant to
Schedule 5.3(vii) hereof) under Tenant Leases); and (b) advise Purchaser of the
commencement of any litigation, condemnation or other judicial or administrative
proceedings affecting the Property of which Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

         13.17             Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby agrees, for a period of six months after Closing,
         to permit Purchaser and Purchaser's accountants access to such books
         and records (including those maintained by Seller's management agent
         for the Property) and to cooperate with Purchaser, and to cause
         Seller's accountants to cooperate with Purchaser, at no cost to Seller,
         to enable such audit to be performed. The provisions of this Section
         13.17(b) shall survive the Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition


                                      -25-


<PAGE>



         of the properties set forth and described in the Dependent Contracts
         pursuant to the terms and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which entitles Seller to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract shall be promptly paid to Seller and
         the earnest money deposits held under the Dependent Contracts shall be
         promptly paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.


                                      -26-


<PAGE>



         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Venture Tech Partners, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Venture
Tech Partners, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not be released from any representations,
warranties, covenants, agreements or obligations hereunder as a result of the
exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         the "Existing Lender"), (ii) that certain Deed of Trust executed by
         Seller for the benefit of the Existing Lender and dated as of even date
         with the Existing Note (the "Existing Deed of Trust"), and (iii) all
         other documents, instruments and agreements securing payment of the
         Existing Note or related to the Existing Note or the Existing Deed of
         Trust (the Existing Note, the Existing Deed of Trust and any and all
         notes, deeds of trust, assignments of leases and rents, security
         agreements, financing statements, agreements, documents or instruments
         executed in connection therewith or related thereto and either
         delivered by Seller to Purchaser or identified in the Assumption
         Agreement (hereinafter defined), as the same may have been or may
         hereafter be amended, supplemented, renewed, extended or restated,
         shall collectively be referred to herein as the "Existing Loan
         Documents," and all indebtedness evidenced by the Existing Loan
         Documents shall be referred to herein as the "Existing Loan").
         Notwithstanding the Purchaser's assumption of Seller's obligations

<PAGE>



Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), One Hundred Three Thousand Nine Hundred Forty-Seven and
No/100 Dollars ($103,947.00) (the "Earnest Money Deposit") in cash or Current
Funds, to be held by the Title Company in escrow to be applied or disposed of by
the Title Company as is provided in this Contract. In the event Purchaser fails
to deposit the Earnest Money Deposit with the Title Company as herein provided,
Seller may, at its option, terminate this Contract, in which event neither
Seller nor Purchaser shall have any further obligations hereunder except for
provisions of this Contract which expressly survive the termination of this
Contract. As used in this Contract, the term "Current Funds" shall mean wire
transfers, certified funds or cashier's checks in a form acceptable to the Title
Company which would permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.

                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-

may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-


<PAGE>



environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

                                       -7-

         Agreements relating to the Property;

         prepared for Seller relating to the Property; and

                  (vii) An updated certified rent roll reflecting all payments
         made by Tenants under Tenants Leases through May 25, 1998.

                  The items identified in (i)-(vii) hereinabove are collectively
         referred to as the "Submission Matters".

         Seller shall allow Purchaser to review and make copies of any other
documents, instruments or agreements it has with respect to the Property at
Seller's offices; provided that, in no event shall Purchaser be allowed to
review any documents which constitute or would be covered by the attorney-client
privilege or the 1998 budgets prepared by or for Seller with respect to the
Property.

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND

                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a)      The representations and warranties of Seller 
         contained herein shall be true, accurate and correct as of the Closing
         Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser 
         contained herein shall be true, accurate and correct as of the Closing
         Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the

the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such

notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                  employees of such manager that are dedicated to property level

Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid

Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for

<PAGE>



with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value

Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses

provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                                      -18-


<PAGE>




                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Twenty-Six Thousand Four
         Hundred and No/100 Dollars ($126,400.00). Notwithstanding anything in
         Section 9.2(a) to the

                                      -20-


<PAGE>



         contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-

after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no

such cooperation shall be without additional cost or liability. The provisions
of this Section 13.16 shall survive the Closing for a period of one year.

         13.17             Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-


<PAGE>



         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other

         right hereunder automatically terminates each of the Dependent

         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Walnut Hill Limited will remain
obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Walnut
Hill Limited.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-

be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

         2.1 Purchase Price. The total Purchase Price (herein so called) to be

Million Two Hundred Ten Thousand and No/100 Dollars ($3,210,000.00). The
Purchase Price shall be payable by Purchaser at Closing as follows:

                  (a) by the payment by Purchaser of cash or Current Funds
         (hereinafter defined) in an amount equal the difference between (i) the

         unpaid interest, of the Existing Note (defined below) as of the date of
         the Closing; and

                  (b) by Purchaser assuming all of the obligations of Seller
         under (i) that certain Promissory Note dated as of October 1, 1996 (the

         Hundred Fifty Thousand and No/100 Dollars ($1,550,000.00), executed by
         Seller and payable to the order of Government Personnel Mutual Life

         herein as the "Existing Lender"), (ii) that certain Deed of Trust
         executed by Seller for the benefit of the Existing Lender and dated as
         of even date with the Existing Note (the "Existing Deed of Trust"), and
         (iii) all other documents, instruments and agreements securing payment
         of the Existing Note or related to the Existing Note or the Existing
         Deed of Trust (the Existing Note, the Existing Deed of Trust and any
         and all notes, deeds of trust, assignments of leases and rents,
         security agreements, financing statements, agreements, documents or
         instruments executed in connection therewith or related thereto and
         either delivered by Seller to Purchaser or identified in the Assumption
         Agreement (hereinafter defined), as the same may have been or may
         hereafter be amended, supplemented, renewed, extended or restated,
         shall collectively be referred to herein as the "Existing Loan
         Documents," and all indebtedness evidenced by the Existing Loan
         Documents shall be referred to herein as the "Existing Loan").
         Notwithstanding the Purchaser's assumption of Seller's obligations

         funds held by the Existing Lender in any escrow, reserve or similar
         accounts pursuant to the terms of the Existing Loan Documents (the
         "Existing Escrow Accounts") are held for the benefit of Seller, and at
         Closing the Purchaser shall be obligated to pay to Seller the total
         amounts held in all such accounts as of the Closing Date. All amounts
         held in the Existing Escrow Accounts shall be paid by Purchaser to
         Seller at the Closing in cash.

Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), One Hundred Five Thousand Five Hundred Ninety-Two and
No/100 Dollars ($105,592.00) (the "Earnest Money Deposit") in cash or Current
Funds, to be held by the Title Company in escrow to be applied or disposed of by
the Title Company as is provided in this Contract. In the event Purchaser fails
to deposit the Earnest Money Deposit with the Title Company as herein provided,
Seller may, at its option, terminate this Contract, in which event neither
Seller nor Purchaser shall have any further obligations hereunder except for
provisions of this Contract which expressly survive the termination of this
Contract. As used in this Contract, the term "Current Funds" shall mean wire
transfers, certified funds or cashier's checks in a form acceptable to the Title
Company which would permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-


<PAGE>



may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-

environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

                                       -7-

         referred to as the "Submission Matters".

         Seller shall allow Purchaser to review and make copies of any other
documents, instruments or agreements it has with respect to the Property at

privilege or the 1998 budgets prepared by or for Seller with respect to the
Property.

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained 
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser 
         contained herein shall be true, accurate and correct as of the Closing 
         Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3      Estoppel Certificates.  Prior to Closing, Seller shall deliver
to each Tenant an Estoppel Certificate (herein so called), in the form attached 
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-


<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing
Date").

         8.2 Items to be Delivered at the Closing.

                  (a) Seller. At the Closing, Seller shall deliver, or cause to
         be delivered, to the Title Company for recording or delivery to
         Purchaser, as applicable, each of the following items:

                  Title Company for the benefit of and at the expense of
                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                           (ii) A Special Warranty Deed (the "Deed") duly
                  executed and acknowledged by Seller in the form attached
                  hereto as Exhibit B and made a part hereof for all purposes
                  sufficient to convey to Purchaser good and indefeasible title
                  to the Land and Improvements free and clear of all liens and
                  encumbrances except for the Permitted Exceptions.

                           (iii) An Assignment and Assumption of Leases and
                  Commission Agreements (the "Assignment of Leases") duly
                  executed and acknowledged by Seller in the form attached
                  hereto as Exhibit C and made a part hereof for all purposes.

                  Assignment ("Bill of Sale") duly executed by Seller in the
                  form attached hereto as Exhibit D and made a part hereof for
                  all purposes.

                           (v) The Estoppel Certificates as required pursuant to

charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments

exclusively by Purchaser. All other expenses incurred by Seller and Purchaser
with respect to the Closing, including, but not limited to, the attorneys' fees
and costs and expenses incurred in connection with negotiating, preparing and

due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for

the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value
of the Property or for the tax rate) for the year of Closing are not available

Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid

provide services to the Property.

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1 Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Twenty-Eight Thousand Four
         Hundred and No/100 Dollars ($128,400.00). Notwithstanding anything in
         Section 9.2(a) to

                                      -20-


<PAGE>



         the contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-

Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the

Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's

Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of
the Deed by Seller to Purchaser.

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of this Contract or any amendments or exhibits hereto. In case any one or more
of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are
references to exhibits attached hereto, all of which are hereby made a part

that time is of the essence with respect to this Contract and Closing hereunder.

         13.11 Multiple Counterparts. This Contract may be executed in a number
of identical counterparts. If so executed, each of such counterparts is to be

counterpart.

         13.12 Risk of Loss. Risk of loss or damage to the Property, or any part

         13.14 Business Days. All references to "business days" contained herein
are references to normal working business days, i.e., Monday through Friday of
each calendar week, exclusive of federal and national bank holidays. In the
event that any event hereunder is to occur, or a time period is to expire, on a
date which is not a business day, such event shall occur or such time period
shall expire on the next succeeding business day.

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which

the parties were originally obligated to deliver by the terms of this Contract,
such cooperation shall be without additional cost or liability. The provisions
of this Section 13.16 shall survive the Closing for a period of one year.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-


<PAGE>



         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which

                                      -27-


<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, I.P. Business Center, L.P. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of I.P.
Business Center, L.P.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-


<PAGE>



be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

                           SELLER:

Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), Fifty-Eight Thousand Five Hundred Fifty-Three and No/100
Dollars ($58,553.00) (the "Earnest Money Deposit") in cash or Current Funds, to
be held by the Title Company in escrow to be applied or disposed of by the Title
Company as is provided in this Contract. In the event Purchaser fails to deposit
the Earnest Money Deposit with the Title Company as herein provided, Seller may,
at its option, terminate this Contract, in which event neither Seller nor
Purchaser shall have any further obligations hereunder except for provisions of
this Contract which expressly survive the termination of this Contract. As used
in this Contract, the term "Current Funds" shall mean wire transfers, certified
funds or cashier's checks in a form acceptable to the Title Company which would
permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-


<PAGE>



may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-


<PAGE>



environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

                                       -7-

by Purchaser at Closing.

to Purchaser and Purchaser hereby acknowledges receipt of the following items:

               (i) A current rent roll for the Property in the form attached to
          this Contract as Schedule 5.3(a) (the "Rent Roll"); and

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

               (a) The representations and warranties of Seller contained herein
          shall be true, accurate and correct as of the Closing Date;

               (b) Seller shall be ready, willing and able to deliver title to
          the Property in accordance with the terms and conditions of this
          Contract;

               (c) The condition specified in Section 7.3 hereof shall have been
          satisfied; and

               (d) Seller shall have delivered all the documents and other items
          required pursuant to Section 8.2(a), and shall have performed, in all
          material respects, all other covenants, undertakings and obligations,
          and complied with all conditions required by this Contract to be
          performed or complied with by the Seller at or prior to the Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

               (a) the representations and warranties of Purchaser contained
          herein shall be true, accurate and correct as of the Closing Date; and

               (b) Purchaser shall have delivered the funds required hereunder
          and all the documents to be executed by Purchaser set forth in Section
          8.2(b) and shall have performed, in all material respects, all other
          covenants, undertakings and obligations, and complied with all
          conditions required by this Contract to be performed or complied with
          by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to 
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-


<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing
Date").

                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                           (ii) A Special Warranty Deed (the "Deed") duly

                  sufficient to convey to Purchaser good and indefeasible title
                  to the Land and Improvements free and clear of all liens and
                  encumbrances except for the Permitted Exceptions.

                           (iii) An Assignment and Assumption of Leases and

                  hereto as Exhibit C and made a part hereof for all purposes.

                  terminable by Purchaser after six months without cause or
                  premium, have a management fee of five percent (5%), pay
                  standard leasing commissions and require Purchaser to pay
                  $300,000 to such manager for use exclusively as bonuses to
                  employees of such manager that are dedicated to property level
                  services including, without limitation, accounting and leasing
                  services, with no more than $150,000 of such bonuses being
                  paid prior to the date that is six months after the Closing,
                  provided, however, if Purchaser acquires less than all of the
                  properties under this Contract and the Dependent Contracts
                  pursuant to Section 14.1(f) hereof, then Purchaser shall be
                  entitled to reduce such $300,000 figure on a pro rata basis
                  based upon the purchase prices of the properties not acquired
                  under this Contract and the Dependent Contracts to the
                  aggregate purchase prices of all of the properties under this
                  Contract and the Dependent Contracts.

                  (b)      Purchaser. At the Closing, Purchaser shall deliver 
         to the Title Company, for recording or delivery to Seller, as 
         applicable, each of the following items:

                           (i) The Purchase Price in Current Funds.

                           (ii) The Assignment of Leases, duly executed and
                  acknowledged by Purchaser.

                           (iii) The Bill of Sale, duly executed by Purchaser.

                           (iv) Such additional funds in cash or Current Funds,
                  as may be necessary to cover Purchaser's share of the closing
                  costs and prorations hereunder.

<PAGE>



                           (v) Evidence satisfactory to Seller and the Title
                  Company that the person or persons executing this Contract and
                  the closing documents on behalf of Purchaser have full right,
                  power and authority to do so.

                           (vi) The Notice Letters and Service Contract Notice
                  Letters duly executed by Purchaser.

                           (vii) Other items reasonably requested by the Title
                  Company for the sale of the Property in accordance with this
                  Contract or for administrative requirements for consummating
                  the Closing.

                          (viii) The Management Agreement executed by Purchaser.

                           (ix) The Assumption Agreement executed by Purchaser.

         8.3 Costs of Closing. The escrow fees of the Title Company shall all be
paid equally by Seller and Purchaser. Any and all costs relating to the Title
Policy and any endorsements thereto shall be borne by Purchaser. Any costs,
including, without limitation, recording costs, loan fees and attorneys' fees,
relating to (a) any financing obtained by the Purchaser for the purchase of the
Property (including, without limitation, any loan assumption fees and expenses
charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid
exclusively by Purchaser. All other expenses incurred by Seller and Purchaser
with respect to the Closing, including, but not limited to, the attorneys' fees
and costs and expenses incurred in connection with negotiating, preparing and
closing the transaction contemplated by this Contract, shall be borne and paid
exclusively by the party incurring same, unless otherwise expressly provided in
this Contract.

         8.4 Prorations. All normal and customarily proratable items, including,
without limitation, rents (including, without limitation, base rents, additional
rents, percentage rents and common area maintenance charges but excluding
Delinquent Rent [hereinafter defined] that is more than thirty (30) days past
due) which shall be prorated based upon the updated Rent Roll delivered by
Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for
all of same attributable to the period up to the Closing Date (and credited for
any amounts paid by Seller attributable to the period on or after the Closing
Date) and Purchaser being responsible for, and credited or charged, as the case
may be, for all of same attributable to the period on and after the Closing
Date. All unapplied Deposits under Tenant Leases, if any, and all prepaid rents
paid by Tenants under Tenant Leases (but only to the extent such rents are for
periods from and after the Closing Date) shall be credited to Purchaser against
the Purchase Price at the Closing. Any real estate ad valorem or similar taxes
for the Property, or any installment of assessments payable in installments
which installment is payable in the year of Closing, shall be prorated to the
date of Closing, based upon actual days involved. In connection

                                      -17-


<PAGE>



with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value
of the Property or for the tax rate) for the year of Closing are not available
at the Closing Date, the proration shall be made using figures from the
preceding year for the figures which are unavailable for the year of Closing.
All prorations hereunder shall be final and unadjustable.

         8.5 New Leases. Notwithstanding anything contained in this Contract to
the contrary, Purchaser shall be responsible for the costs of all tenant
improvement expenses and leasing commissions payable or attributable to any new
Tenant Leases entered into by Seller after June 1, 1998 and prior to the Closing
Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7      Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.


                                      -18-


<PAGE>



                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1      Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2      Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than Seventy-One Thousand Two Hundred and
         No/100 Dollars ($71,200.00). Notwithstanding anything in Section 9.2(a)
         to the contrary, if

                                      -20-


<PAGE>



         Purchaser has not timely elected to terminate in accordance with
         Section 9.2(a), and if the proceeds payable with respect to the
         Property as a result of casualty exceed the Purchase Price for the
         Property, the portion of such proceeds in excess of the Purchase Price
         shall be paid to Seller (in addition to the Purchase Price) at the
         Closing. The foregoing provision shall survive the Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-


<PAGE>



after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

                                  ARTICLE XIII.

this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with

Contract by Purchaser, Purchaser shall not be released from any liability or

         13.6 Headings. Headings used in this Contract are used for reference
purposes only and do not constitute substantive matter to be considered in
construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no
representations, warranties, covenants, acknowledgments or agreements contained
in this Contract shall survive the Closing of this Contract and the delivery of

         13.8 Interpretation. The parties acknowledge that each party and its
counsel have reviewed this Contract, and the parties hereby agree that the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation

of the provisions contained in this Contract shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Contract
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. When the context in which words are used in this
Contract indicates that such is the intent, words in the singular number shall
include the plural and vice versa, and words in the masculine gender shall
include the feminine and neuter genders and vice versa.

         13.9 Exhibits. All references to "Exhibits" contained herein are

         13.11 Multiple Counterparts. This Contract may be executed in a number

         13.15 No Recordation of Contract. In no event shall this Contract or
any memorandum hereof be recorded in the public records of the place in which

of this Section 13.16 shall survive the Closing for a period of one year.

         13.17             Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-

         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which

                                      -27-


<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, I.P. Business Center, L.P. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of I.P.
Business Center, L.P.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-


<PAGE>



be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), One Hundred Thirty-Five Thousand Eight Hundred Fifty-Five
Dollars and No/100 Dollars ($135,855.00) (the "Earnest Money Deposit") in cash
or Current Funds, to be held by the Title Company in escrow to be applied or
disposed of by the Title Company as is provided in this Contract. In the event
Purchaser fails to deposit the Earnest Money Deposit with the Title Company as
herein provided, Seller may, at its option, terminate this Contract, in which
event neither Seller nor Purchaser shall have any further obligations hereunder
except for provisions of this Contract which expressly survive the termination
of this Contract. As used in this Contract, the term "Current Funds" shall mean
wire transfers, certified funds or cashier's checks in a form acceptable to the
Title Company which would permit the Title Company to immediately disburse such
funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-


<PAGE>



may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-

environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

         referred to as the "Submission Matters".

         Seller shall allow Purchaser to review and make copies of any other

privilege or the 1998 budgets prepared by or for Seller with respect to the
Property.

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based
upon the "as is" nature of the sale contemplated hereunder.

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller 
         contained herein shall be true, accurate and correct as of the Closing 
         Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser 
         contained herein shall be true, accurate and correct as of the Closing 
         Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates.  Prior to Closing, Seller shall deliver 
to each Tenant an Estoppel Certificate (herein so called), in the form 
attached hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-


<PAGE>



obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than two percent
(2%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

                                  ARTICLE VIII.

                                     CLOSING

         8.1 Time and Place. The consummation of the purchase and sale of the
Property (the "Closing") shall take place at the office of the Title Company (it
being contemplated that the Closing will occur by the delivery of Closing
documents into escrow with the Title Company) on July 3, 1998, or at such
earlier date and time as Purchaser and Seller may mutually agree (the "Closing

                  Purchaser, and insuring Purchaser's title in the amount of the
                  Purchase Price, subject only to the Permitted Exceptions (the
                  "Title Policy").

                           (ii) A Special Warranty Deed (the "Deed") duly

receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid
such expenses and/or leasing commissions prior to Closing, Purchaser shall be
responsible for payment of all such expenses and/or leasing commissions after
Closing.

         8.6 Possession and Closing. Possession of the Property shall be
delivered to Purchaser by Seller at the Closing, subject to the Permitted
Exceptions and the rights of the Tenants under Tenant Leases. Purchaser shall
make its own arrangements for the provision of public utilities to the Property
and Seller shall terminate its contracts with such utility companies that
provide services to the Property.

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1 Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Sixty-Five Thousand Two
         Hundred and No/100 Dollars ($165,200.00). Notwithstanding anything in
         Section 9.2(a) to the

                                      -20-


<PAGE>



         contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-


<PAGE>



after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

                                  ARTICLE XIII.

         13.4 Parties Bound. Subject to the provisions of Section 13.5 hereof,
this Contract shall be binding upon and inure to the benefit of Seller and
Purchaser, and their respective heirs, personal representatives, successors and
assigns.

         13.5 Assignment. This Contract may be assigned by Purchaser to any
person or entity controlling, controlled by or under common control with
Purchaser without the prior written consent of Seller. Any assignment of this
Contract by Purchaser other than as provided foregoing shall, at Seller's

Contract by Purchaser, Purchaser shall not be released from any liability or
obligations hereunder.

         13.6 Headings. Headings used in this Contract are used for reference

         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with

                                  ARTICLE XIV.

                               SPECIAL PROVISIONS

         14.1 Dependent Contracts. Seller and Purchaser acknowledge that on the
Effective Date of this Contract, Purchaser entered into those certain contracts
of sale described in Schedule 14.1 hereof (collectively, the "Dependent
Contracts"). Notwithstanding anything contained in this Contract to the
contrary, Seller and Purchaser agree with respect to the Dependent Contracts as
follows:

                  (a) Purchaser's obligations under this Contract to purchase
         the Property is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (b) Seller's obligations under this Contract to sell the
         Property to Purchaser is expressly subject to and conditioned upon the
         consummation of the closing of the acquisition of the properties set
         forth and described in the Dependent Contracts pursuant to the terms
         and conditions thereof;

                  (c) A default by Purchaser or any of the sellers (the
         "Dependent Sellers") under any of the Dependent Contracts shall be
         deemed to be a default by Purchaser or Seller, respectively, under this
         Contract and shall entitle such non-defaulting party to the rights and
         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to
         a right hereunder automatically terminates each of the Dependent
         Contracts and a termination by Purchaser of any of the Dependent
         Contracts automatically terminates this Contract and the other
         Dependent Contracts and any termination of this Contract by Purchaser
         which entitles Purchaser to receive the Earnest Money Deposit shall
         terminate all of the other Dependent Contracts and the Earnest Money
         Deposit held under this Contract and the earnest money deposits held
         under the Dependent Contracts shall be promptly returned to Purchaser;

                  (e) The termination by Seller of this Contract pursuant to a
         right hereunder automatically terminates each of the Dependent
         Contracts and a termination by any of the Dependent Sellers of any of
         the Dependent Contracts automatically terminates this Contract and the
         other Dependent Contracts and any termination of this Contract by
         Seller which

                                      -27-


<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Properties of Floyd Road, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Properties
of Floyd Road, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-


<PAGE>



be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.

                         SELLER:

Preston Road, Suite 100, Dallas, Texas 75225, Attention: J. David Griffin, Esq.
(the "Title Company"), Ninety-Seven Thousand Two Hundred Four Dollars and No/100
Dollars ($97,204.00) (the "Earnest Money Deposit") in cash or Current Funds, to
be held by the Title Company in escrow to be applied or disposed of by the Title
Company as is provided in this Contract. In the event Purchaser fails to deposit
the Earnest Money Deposit with the Title Company as herein provided, Seller may,
at its option, terminate this Contract, in which event neither Seller nor
Purchaser shall have any further obligations hereunder except for provisions of
this Contract which expressly survive the termination of this Contract. As used
in this Contract, the term "Current Funds" shall mean wire transfers, certified
funds or cashier's checks in a form acceptable to the Title Company which would
permit the Title Company to immediately disburse such funds.

         3.2 Application and Interest. If the purchase and sale hereunder is
consummated, then the Earnest Money Deposit shall be applied to the Purchase
Price at Closing. In all other events, the Earnest Money Deposit shall be
disposed of by the Title Company as provided in this Contract. The Earnest Money
Deposit shall be invested in an interest-bearing account with a financial
institution and in a manner reasonably acceptable to Purchaser. All interest
earned on the Earnest Money Deposit is part of the Earnest Money Deposit, to be
applied or disposed of in the same manner as the Earnest Money Deposit under
this Contract.

         3.3 Independent Contract Consideration. At the same time as the deposit
of the Earnest Money Deposit with the Title Company, Purchaser shall deliver to
Seller a check in the sum of Fifty and No/100 Dollars ($50.00) (the "Independent
Contract Consideration"), which amount has been bargained for and agreed to as
consideration for Purchaser's right to purchase the Property and the Inspection
Period (hereinafter defined) provided for herein, and for Seller's execution and
delivery of this Agreement. The Independent Contract Consideration is in
addition to and independent of all other consideration provided for in this
Agreement, and is non-refundable in all events.

                                   ARTICLE IV.

                                TITLE AND SURVEY

         4.1 Title Commitment. On or before the Effective Date, Seller shall
cause to be furnished to Purchaser a current Commitment for Title Insurance for
the Land and Improvements (the "Title Commitment") issued by the Title Company.
The Title Commitment shall set forth the state of title to the Land and
Improvements, including a list of conditions or exceptions to title affecting
the Land and Improvements that would appear in an Owner's Policy of Title
Insurance, if one were issued. The Title Commitment shall contain the expressed
commitment of the Title Company to issue the Title Policy (hereinafter defined)
to Purchaser in the amount of the Purchase Price, insuring the title to the Land
and Improvements specified in the Title Commitment. At such time as the Title
Commitment is furnished to Purchaser, the Title Company also shall furnish to
Purchaser copies of instruments or documents (the "Exception Documents") that
create or evidence conditions or exceptions to title affecting the Land and
Improvements, as described in the Title Commitment.


                                       -3-


<PAGE>



         4.2 Survey. On or before the Effective Date, Seller shall cause to be
furnished to Purchaser, at Seller's expense, a copy a survey of the Land and
Improvements (the "Survey") dated or recertified no earlier than thirty (30)
days prior to the Effective Date and certified to Purchaser and the Title
Company in a manner reasonably acceptable to Purchaser. Notwithstanding the
foregoing, in the event Purchaser elects to terminate this Contract pursuant to
Section 4.4 or 5.2 hereof, Purchaser shall be obligated to reimburse Seller on
demand for the reasonable expenses incurred by Seller in connection with
obtaining the Survey.

         4.3 Review of Title and Survey. Purchaser shall have until the
expiration of the Inspection Period in which to notify Seller in writing (the
"Title Objection Notice") of any objections Purchaser has to any matters shown
or referred to in the Title Commitment, the Exception Documents or on the
Survey; provided, that Purchaser shall not object to current real estate taxes
and assessments or to easements, restrictions and exceptions affecting the
Property which do not materially adversely affect the value of the Property or
its current use by Seller, all of which shall be Permitted Exceptions hereunder.
Any title encumbrances, exceptions or other matters which are set forth in the
Title Commitment, the Exception Documents or on the Survey, and to which
Purchaser does not object within the Inspection Period, shall be deemed to be
permitted exceptions to the status of Seller's title (such encumbrances,
exceptions or other matters, together with such other matters included pursuant
to other provisions of this Contract, shall be referred to as the "Permitted
Exceptions"). Other than liens securing the payment of the Existing Loan which
will be assumed by Purchaser at Closing pursuant to the terms of this Contract,
Seller shall, notwithstanding anything to the contrary contained herein, satisfy
all liens securing the payment of a monetary obligation and affecting the
Property at or prior to Closing, except for any liens or encumbrances expressly
permitted in Section 4.5(c) and (d) hereof.

         4.4 Objections to Status of Title and Survey. If Purchaser properly
objects to any item shown or referred to in the Title Commitment, Exception
Documents or Survey within the Inspection Period, Seller shall be given until
five (5) days after receipt of the Title Objection Notice to notify Purchaser
whether or not Seller will cure, prior to Closing and at Seller's option and
sole discretion but without any obligation to do so, any objection to the
condition of title raised by Purchaser. If Seller notifies Purchaser that it
elects not to cure any such objections, then Purchaser may, at its option
exercisable within five (5) days following the date of receipt by Purchaser of
written notice from Seller stating that Seller is unable or unwilling to cure
such objections, either (a) accept such title as Seller can deliver, in which
case all exceptions to title set forth in the Title Commitment, Exception
Documents and Survey which are not removed shall be deemed to be Permitted
Exceptions, or (b) terminate this Contract by notice in writing to Seller in
which event the Title Company shall return the Earnest Money Deposit to
Purchaser and neither party shall have any further rights, duties or obligations
hereunder, except for provisions of this Contract which expressly survive
termination of this Contract. In the event Purchaser fails to notify Seller,
within such five (5) day period, that Purchaser has elected to proceed under
either subpart (a) or (b) of the immediately preceding sentence, Purchaser shall
be deemed to have elected to proceed under subpart (a), and this Contract shall
remain in full force and effect. If Seller notifies Purchaser that it elects to
cure any such objections but is unable to cure same by Closing or if Seller
fails to notify Purchaser of its intentions with respect to such objections and
fails to cure same by Closing, then Purchaser

                                       -4-

may, at its option, either (x) accept such title as Seller can deliver in which
case the parties shall proceed with Closing and all exceptions to title set
forth in the Title Commitment, Exception Documents and Survey which are not
removed shall be deemed to be Permitted Exceptions, or (y) terminate this
Contract by notice in writing to Seller at Closing, in which event the Title
Company shall return the Earnest Money Deposit to Purchaser and neither party
shall have any further rights, duties or obligations hereunder except for
provisions of this Contract which expressly survive termination of this
Contract. If any additional exceptions to title other than those shown on the
initial Title Commitment or Survey arise between the date of the initial Title
Commitment, the Survey and the Closing (such exceptions to title being referred
to herein as the "New Exceptions"), Purchaser shall have five (5) business days
after its receipt of written notice of such New Exceptions within which to
notify Seller of any such New Exceptions to which Purchaser objects. Any such
New Exceptions not objected to by Purchaser as aforesaid shall become "Permitted
Exceptions" hereunder; provided, however, all New Exceptions created, caused by,
or consented to by Seller shall be satisfied or removed at Closing and shall not
constitute Permitted Exceptions unless such New Exceptions are expressly
permitted in Section 4.5(c) or (d) hereof. If Purchaser objects to any such New
Exceptions, Seller shall have until Closing to remove such New Exceptions, which
removal may be accomplished by waiver or endorsement by the Title Company
reasonably satisfactory to Purchaser. If Seller fails to remove any such New
Exceptions as aforesaid, Purchaser may, as its sole and exclusive remedy,
terminate this Contract and obtain a return of the Earnest Money Deposit and
neither party shall have any further rights, duties, or obligations hereunder
except for provisions of the Contract which expressly survive the termination of
this Contract. If Purchaser does not elect to terminate this Agreement,
Purchaser shall consummate the Closing and accept title to the Property subject
to all such New Exceptions (in which event, all such New Exceptions, together
with all other Permitted Exceptions, shall be deemed "Permitted Exceptions"
hereunder).

         4.5 Other Permitted Exceptions. The Permitted Exceptions shall include
those matters shown in the Title Commitment and the Survey which become
Permitted Exceptions pursuant to Sections 4.3 and 4.4 above and, in addition,
the following: (a) the Tenant Leases; (b) taxes and assessments for the year in
which Closing occurs and subsequent years that are not yet due and payable; (c)
liens and encumbrances arising after the date hereof to which Purchaser consents
in writing; and (d) any liens or encumbrances of a definite or ascertainable
amount not exceeding $50,000.00 for the Property (and when such amount is added
to the aggregate amounts of any liens or encumbrances to be insured and bonded
around by the respective Dependent Sellers (hereinafter defined) under the
Dependent Contracts (hereinafter defined), such aggregate amount shall not
exceed $125,000.00), provided that (i) Seller causes such liens or encumbrances
to be insured or bonded around such that same do not appear as an exception in
the Title Policy issued to Purchaser pursuant to the Commitment, and (ii) Seller
agrees to indemnify Purchaser from all losses incurred by Purchaser as a result
of such liens or encumbrances.

                             INSPECTION BY PURCHASER

         5.1 Inspection Period. Purchaser shall have a period of time commencing
on the Effective Date and expiring at 5:00 p.m., Dallas, Texas time on June 17,
1998 (the "Inspection Period") within which to examine the Property and to
conduct its feasibility study thereof. Seller agrees that, during the Inspection
Period, Seller will allow Purchaser and Purchaser's agents access to the
Property during normal business hours to conduct soil and engineering, hazardous
waste, marketing, feasibility, zoning and other studies or tests and to
otherwise determine the feasibility of the Property for Purchaser's intended
use; provided, however, that prior to conducting any invasive testing with
respect to the Land or Improvements, or any tests or studies which could cause
any damage to the Land or Improvements, Purchaser must advise Seller in writing
(which notice shall state in reasonable detail the nature and extent of such
proposed testing) of its intent to conduct such tests or studies and Seller may,
in its reasonable discretion, refuse to approve any such tests or studies, in
which event Purchaser's sole remedy shall be to terminate this Contract pursuant
to Section 5.2 hereof and receive a refund of the Earnest Money Deposit, all as
provided in said Section 5.2. Seller agrees that, during the Inspection Period,
Seller will allow Purchaser and Purchaser's agents to conduct interviews with
the Tenants set forth on Schedule 5.1 attached hereto and made a part hereof,
and with those certain Tenants which Purchaser notifies Seller in writing during
the Inspection Period that Purchaser desires to conduct interviews and which
Seller consents to, which consent shall not be unreasonably withheld, provided
that such interviews shall take place during normal business hours after
reasonable notice (which may be by telephone) to Seller, and such interviews
shall be conducted only in the presence of one of Seller's representatives. Not
withstanding the foregoing, (a) the costs and expenses of Purchaser's
investigation shall be borne solely by Purchaser, (b) prior to the expiration of
the Inspection Period, Purchaser shall restore the Property to the condition
which existed prior to Purchaser's entry thereon and investigation thereof to
the extent the condition of the Property was affected by or as a result of the
actions of Purchaser or its agents, contractors or representatives, (c)
Purchaser shall not, in Seller's reasonable opinion, materially interfere,
interrupt or disrupt the operation of Seller's business on the Property and,
further, such access by Purchaser and/or its agents shall be subject to the
rights of Tenants under Tenant Leases, (d) in the event the transaction
contemplated by this Contract does not close for any reason, Purchaser shall
deliver to Seller a descriptive listing of all tests, reports and inspections
conducted by Purchaser with respect to the Property and deliver copies thereof
to Seller (excluding, however, any proprietary development or marketing
materials), (e) Purchaser shall not permit any mechanic's or materialman's liens
or any other liens to attach to the Property by reason of the performance of any
work or the purchase of any materials by Purchaser or any other party on
Purchaser's behalf in connection with any studies or tests conducted pursuant to
this Section 5.1, (f) Purchaser shall give notice (which may be by telephone) to
Seller a reasonable time prior to entry onto the Property and shall permit
Seller to have a representative present during all investigations and
inspections conducted with respect to the Property, and (g) Purchaser shall take
all reasonable actions and implement all protections necessary to ensure that
all actions taken in connection with the investigations and inspections of the
Property, and all equipment, materials and substances generated, used or brought
onto the Property pose no material threat to the safety of persons or the

                                       -6-


<PAGE>



environment and cause no damage to the Property or other property of Seller or
other persons. All information made available by Seller to Purchaser in
accordance with this Contract or obtained by Purchaser in the course of its
investigations shall be treated as confidential information by Purchaser, and,
prior to the purchase of the Property by Purchaser, Purchaser shall use its best
efforts to prevent its agents and employees from divulging such information to
any third parties except (i) as reasonably necessary to third parties engaged by
Purchaser for the limited purpose of analyzing and investigating such
information for the purpose of consummating the transaction contemplated by this
Contract, including Purchaser's attorneys and representatives, prospective
lenders and engineers or (ii) as may required by applicable law, unless such
information is generally available to the public or is disclosed by a party
other than Purchaser or its agents. Purchaser shall indemnify, defend and hold
Seller harmless for, from and against any and all claims, liabilities, causes of
action, damages, liens, losses, costs and expenses (including, without
limitation, reasonable attorneys' fees) incident to, resulting from or in any
way arising out of any of Purchaser's and its agents', contractors' and
representatives' activities on the Property, including, without limitation, any
tests or inspections conducted by Purchaser or its agents, contractors or
representatives on the Property. The agreements contained in this Section 5.1
shall survive the Closing and not be merged therein and shall also survive any
termination of this Contract.

         5.2 Approval of Inspections. If Purchaser determines at any time prior
to the expiration of the Inspection Period that the Property is not satisfactory
to Purchaser, then Purchaser may deliver written notice to Seller within such
Inspection Period, given in accordance with the provisions of Section 13.1
hereof, in which event the Title Company shall return the Earnest Money Deposit
to Purchaser and neither party shall have any further rights, liabilities or
obligations hereunder, except for provisions of this Contract which by their
terms expressly survive the termination of this Contract. If Purchaser does not
timely deliver written notice of termination within such Inspection Period, the
conditions of this Section 5.2 shall be deemed satisfied, and Purchaser shall be
deemed to have approved the condition of the Property and may not thereafter
terminate this Contract pursuant to this Section 5.2. Prior to the end of the
Inspection Period, Purchaser shall deliver written notice (the "Service Contract
Termination Notice") to Seller of any Service Contracts which Purchaser does not
wish to assume; provided, that Purchaser shall be required to assume any Service
Contracts which are not terminable by notice within the time between Seller's
receipt of such Service Contract Termination Notice and the Closing Date
(hereinafter defined). Any Service Contracts which Purchaser does not specify be
terminated in the Service Contract Termination Notice delivered prior to the end
of the Inspection Period, and any Service Contracts specified in the Service
Contract Termination Notice which cannot be terminated without penalty prior to
the Closing Date, shall be deemed approved by Purchaser and shall be assumed by
Purchaser at Closing. Prior to the end of the Inspection Period, Purchaser shall
deliver written notice (the "Commission Agreement Termination Notice") to Seller
of any Commission Agreements which Purchaser does not wish to assume; provided,
that Purchaser shall be required to assume any Commission Agreements which are
not terminable by notice within the time between Seller's receipt of such
Commission Agreement Termination Notice and the Closing Date. Any Commission
Agreements which Purchaser does not specify be terminated in the Commission
Agreement Termination Notice delivered prior to the end of the Inspection
Period, and any Commission Agreements specified in the Commission Agreement
Termination Notice which either cannot be terminated or cannot be terminated
without penalty prior

                                       -7-

                  The items identified in (i)-(vii) hereinabove are collectively
         referred to as the "Submission Matters".

         Seller shall allow Purchaser to review and make copies of any other
documents, instruments or agreements it has with respect to the Property at
Seller's offices; provided that, in no event shall Purchaser be allowed to
review any documents which constitute or would be covered by the attorney-client
privilege or the 1998 budgets prepared by or for Seller with respect to the
Property.

         6.4 Effect of Disclaimers. As specified in Section 6.3 above, the
Property will be sold in its "as is" condition. Except for the representations
and warranties of Seller in this Contract and the warranties contained in the
documents to be delivered by Seller to Purchaser at Closing, Purchaser shall
rely on its own due diligence in deciding to enter into and close the
transaction contemplated by this Contract. The price has been negotiated based

                                  ARTICLE VII.

                     CONDITIONS PRECEDENT TO PURCHASER'S AND
                              SELLER'S PERFORMANCE

         7.1 Conditions to Purchaser's Obligations. Purchaser's obligation under
this Contract to purchase the Property is subject to the fulfillment of each of
the following conditions (any or all of which may be waived by Purchaser):

                  (a) The representations and warranties of Seller contained
         herein shall be true, accurate and correct as of the Closing Date;

                  (b) Seller shall be ready, willing and able to deliver title
         to the Property in accordance with the terms and conditions of this
         Contract;

                  (c) The condition specified in Section 7.3 hereof shall have
         been satisfied; and

                  (d) Seller shall have delivered all the documents and other
         items required pursuant to Section 8.2(a), and shall have performed, in
         all material respects, all other covenants, undertakings and
         obligations, and complied with all conditions required by this Contract
         to be performed or complied with by the Seller at or prior to the
         Closing.

         7.2 Conditions to Seller's Obligations. Seller's obligation under this
Contract to sell the Property to Purchaser is subject to the fulfillment of each
of the following conditions (all or any of which may be waived by Seller):

                  (a) the representations and warranties of Purchaser contained
         herein shall be true, accurate and correct as of the Closing Date; and

                  (b) Purchaser shall have delivered the funds required
         hereunder and all the documents to be executed by Purchaser set forth
         in Section 8.2(b) and shall have performed, in all material respects,
         all other covenants, undertakings and obligations, and complied with
         all conditions required by this Contract to be performed or complied
         with by Purchaser at or prior to Closing.

         7.3 Estoppel Certificates. Prior to Closing, Seller shall deliver to
each Tenant an Estoppel Certificate (herein so called), in the form attached
hereto as Exhibit F, and request that each

                                      -12-


<PAGE>



Tenant complete, sign and deliver such Estoppel Certificate to Seller. Seller's
only obligation with respect to such Estoppel Certificates shall be to request
that each Tenant complete and deliver to Seller such Estoppel Certificates.
Purchaser's obligations to consummate the transaction contemplated by this
Contract are expressly subject to and conditioned upon (x) Seller delivering to
Purchaser on or before the Closing Date Estoppel Certificates dated no earlier
than thirty (30) days prior to the Closing Date (unless the Closing Date is
automatically extended pursuant to Section 7.4 hereof, in which case such thirty
(30) day period shall be extended on a day for day basis by the period of the
automatic extension), executed by Tenants occupying at least seventy percent
(70%) of the net rentable area of the Improvements, in the aggregate, and from
all Tenants set forth in Schedule 7.3 attached hereto and made a part hereof
(the "Required Estoppels"), and (y) Seller delivering to Purchaser at Closing a
Seller's Certificate for each Tenant that has not delivered an Estoppel
Certificate on or before Closing. Seller shall be obligated to deliver to
Purchaser at Closing a Seller's Certificate for each Tenant that has not
delivered an Estoppel Certificate on or before Closing. If on or before the
Closing Date Seller has received Estoppel Certificates from Tenants occupying
more than sixty percent (60%) but less than seventy percent (70%) of the net
rentable area of the Improvements, then, at Closing, Seller at its option may
(without any obligation to do so) provide Purchaser with a certificate (herein
called the "Seller's Certificate"), setting forth Seller's certification that,
with respect to the Lease in question for which a Tenant did not deliver an
Estoppel Certificate, (i) the copy of such Lease (and all amendments and
modifications thereto) previously provided by Seller to Purchaser is true,
correct and complete, (ii) Seller has not received any rent thereunder for more
than one month in advance, and (iii) Seller has neither received nor given any
written notice of default under such Lease (or, if so, describing the nature
thereof). Each Seller's Certificate provided to Purchaser as provided in the
immediately preceding sentence shall be in lieu of and in substitution for the
Estoppel Certificate with respect to the Lease in question and shall count
against the minimum seventy percent (70%) requirement set forth in the
conditions set forth above, but only to the extent of such ten percent (10%) or
less shortfall and no Seller's Certificate may be delivered by Seller in
substitution for or count against the requirement to obtain any of the Required
Estoppels. In the event that an Estoppel Certificate is received from a Tenant
either before or within thirty (30) days after Closing which confirms the
accuracy of the certification set forth in the updated and certified rent roll
delivered by Seller to Purchaser at Closing with respect to the corresponding
Lease, the certified and updated rent roll shall be deemed to be superseded by
such Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to that portion of the certification
superseded. In the event that an Estoppel Certificate is received from a Tenant
on or before thirty (30) days after the Closing and delivered by Seller to
Purchaser within such thirty-day period which confirms the accuracy of the
representations made by Seller in a Seller's Certificate delivered by Seller at
Closing, then such Seller's Certificate shall be deemed to be superseded by such
Estoppel Certificate and, in such event, Seller shall no longer have any
liability hereunder with respect to the Seller's Certificate relating to the
Tenant Lease in question. The provisions of this Section shall survive the
Closing and delivery of the Deed.

         7.4 Requisite Approvals. Seller agrees that it will promptly seek the
requisite approval and consent to this Contract and to the sale and transfer of
the Property to Purchaser from the Existing Lender (the "Existing Lender
Approval"). Purchaser shall promptly provide all documents, instruments and
agreements reasonably requested by the Existing Lender in connection with

                                      -13-

obtaining its consent as aforesaid. In the event that Seller has not obtained
the Existing Lender Approval prior to the Closing Date at a cost to Purchaser of
no greater than the sum of (x) an assumption fee of no greater than one percent
(1%) of the outstanding principal balance of the Existing Loan plus (y) any
reasonable costs and expenses of the Existing Lender in connection with such
assumption including, without limitation, attorney's fees, then either Seller or
Purchaser may, at their option, terminate this Contract by delivery of written
notice of termination to the other party, whereupon the Earnest Money Deposit
shall be returned to Purchaser and the parties shall have no further obligations
hereunder except for the provisions of this Contract which by the terms of this
Contract shall survive its termination. Notwithstanding the foregoing, in the
event that Seller has not obtained the Existing Lender Approval on or prior to
the Closing Date, then the Closing Date shall be automatically extended for up
to thirty (30) days to enable Seller to obtain such approval without the
necessity of Seller and Purchaser executing any further amendments to this
Contract.

charged by the Existing Lender in connection with the assumption of the Existing
Loan), and/or (b) any documentary stamp taxes, deed taxes, transfer taxes,
intangible taxes, mortgage taxes or other similar taxes, fees or assessments
incurred in connection with any such financing shall be borne and paid

Seller to Purchaser at Closing, operating expenses and other fees and payments
relating to any agreements affecting the Property which survive the Closing,
shall be prorated as of the Closing Date, Seller being charged and credited for

<PAGE>



with the proration of real property taxes or installments of assessments, such
proration shall be based upon the assessed valuation and tax rate figures for
the year in which the Closing occurs to the extent the same are available;
provided, that in the event that actual figures (whether for the assessed value

Date; provided, that such new Tenant Leases have been delivered by Seller to
Purchaser for Purchaser's approval and Purchaser has approved of such new Tenant
Leases, which approval shall not be unreasonably withheld, conditioned or
delayed, and which shall be deemed approved if Purchaser has not notified Seller
of its rejection of such new Tenant Lease within three (3) business days after
receipt of a request for approval of such new Tenant Lease from Seller (which
request shall be accompanied by a copy of the Tenant Lease in question and the
amount of any leasing commissions relating thereto). In the event that Seller
has paid any of such expenses and/or leasing commissions prior to Closing,
Purchaser shall reimburse Seller at Closing for the amount of any such expenses
and/or leasing commissions paid by Seller and, in the event Seller has not paid

         8.7 Delinquent Rent.

                  (a) Application of Delinquent Rent. If on the Closing Date any
         Tenant is in arrears in the payment of any rent under any Tenant Lease
         (the "Delinquent Rent") payable by it, any Delinquent Rent received by
         Purchaser and Seller from such Tenant after the Closing shall be
         applied to amounts due and payable by such Tenant during the following
         periods in the following order of priority: (i) with respect to any
         Delinquent Rent which is less than one month late, (A) first, to the
         period of time on or before the Closing Date; and (ii) with respect to
         any Delinquent Rent which is one month or more late as of the Closing
         Date, (A) first, to the period of time after the Closing Date, and (B)
         second, to the period of time on or before the Closing Date. If
         Delinquent Rent or any portion thereof received by Seller or Purchaser
         after the Closing are due and payable to the other party by reason of
         this allocation, the appropriate sum, less a proportionate share of any
         reasonable attorneys' fees and costs and expenses expended in
         connection with the collection thereof, shall be promptly paid to the
         other party. The provisions of this Section 8.7(a) shall survive the
         Closing.

<PAGE>



                  (b) Collection of Delinquent Rent. After the Closing, Seller
         shall continue to have the right, in its own name, to demand payment of
         and to collect Delinquent Rent owed to Seller by any Tenant, which
         right shall include, without limitation, the right to continue or
         commence legal actions or proceedings against any Tenant, but shall
         specifically exclude the right to seek possession of the premises
         demised to a Tenant or to terminate a Tenant Lease, and the delivery of
         the Assignment of Leases [as defined in Section 8.2(a)(iii)] shall not
         constitute a waiver by Seller of such right. Purchaser agrees to
         cooperate with Seller in connection with all efforts by Seller to
         collect such Delinquent Rent and to take all steps, whether before or
         after the Closing Date, as may be necessary to carry out the intention
         of the foregoing, including, without limitation, the delivery to
         Seller, upon demand, of any relevant books and records (including,
         without limitation, rent statements, receipted bills and copies of
         tenant checks used in payment of such rent), the execution of any and
         all consents or other documents, and the undertaking of any act
         reasonably necessary for the collection of such Delinquent Rent by
         Seller, but without any obligation to incur any out-of-pocket costs or
         expenses. The provisions of this Section 8.7(b) shall survive the
         Closing.

         8.8 Tenant Reimbursements. Any additional rents, percentage rents,
common area maintenance charges and other rent items that have accrued, but have
not yet been paid for the calendar year 1997 shall be owned exclusively by
Seller and to the extent any of such amounts are paid by Tenants to Purchaser
after the Closing Date, Purchaser shall promptly deliver such amounts to Seller.
Purchaser acknowledges that based upon the operating expenses of the Property
for calendar year 1997 and based upon projected increases in operating expenses
for calendar year 1998, Seller has notified Tenants in writing that estimated
additional rent payments (the "1998 Additional Rent Payments") are required to
be paid by the Tenants at such time as base rent payments are due and payable
during the balance of the 1998 calendar year. Purchaser agrees that at such time
as the 1998 Additional Rent Payments are received from the Tenants after the
Closing Date, Purchaser shall promptly deliver Seller's Pro rata Portion of such
1998 Additional Rent Payments to Seller. As used in this Section 8.8, Seller's
Pro rata Portion shall be equal to the amount expressed in percentage terms
determined by dividing (x) the number of days that Seller owned the Property in
the 1998 calendar year by (y) 365. The provisions of this Section 8.8 shall
survive the Closing.

                                   ARTICLE IX.

                            CONDEMNATION OR CASUALTY

         9.1 Condemnation.

                  (a) In the event that all or any substantial portion of the
         Property is condemned or taken by eminent domain or conveyed by deed in
         lieu thereof, or if any condemnation proceeding is commenced for all or
         any substantial portion of the Property, prior to Closing, Purchaser
         may elect to terminate this Contract by written notice thereof to
         Seller within ten (10) days after Seller notifies Purchaser of the
         condemnation, taking or deed in lieu or institution of such
         condemnation proceeding, and in the case of such termination, the
         Earnest Money Deposit shall be returned to Purchaser and neither party
         shall have any further rights,

                                      -19-


<PAGE>



         duties, or obligations hereunder except for provisions of this Contract
         which expressly survive the termination of this Contract. If Purchaser
         does not terminate this Contract as aforesaid or the taking is not
         substantial, then both parties shall proceed to close the transaction
         contemplated herein pursuant to the terms hereof, in which event Seller
         shall, except as limited in Section 9.1(b) hereof, deliver to Purchaser
         at the Closing any proceeds actually received by Seller attributable to
         the Property from such condemnation, eminent domain proceeding or deed
         in lieu thereof and assign its interest in and to the balance of any
         unpaid proceeds, and there shall be no reduction in the Purchase Price.

                  (b) For the purpose of this Section 9.1(a), a "substantial
         portion" of the Property shall be deemed to be (x) any portion of the
         Improvements, (y) any portion of the Property that restricts or reduces
         the existing access to the Property, or (z) any portion of the parking
         lot that reduces the existing aggregate parking spaces by more than
         five percent (5%) or renders the Property in violation of existing
         zoning requirements. Notwithstanding anything to the contrary contained
         in Section 9.1(a), if Purchaser has not timely elected to terminate in
         accordance with Section 9.1(a), and if the proceeds payable with
         respect to the Property as a result of condemnation exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

         9.2 Casualty.

                  (a) In the event that all or any substantial portion of the
         Property shall be damaged or destroyed by fire or other casualty prior
         to Closing, Purchaser may terminate this Contract by written notice
         thereof to Seller within ten (10) days after Seller notifies Purchaser
         of the casualty, and in the case of such termination, the Earnest Money
         Deposit shall be returned to Purchaser and neither party shall have any
         further rights, duties, or obligations hereunder except for provisions
         of this Contract which expressly survive the termination of this
         Contract. If Purchaser does not terminate this Contract as aforesaid,
         then both parties shall proceed to close the transaction contemplated
         herein pursuant to the terms hereof, in which event Seller shall,
         except as limited in Section 9.2(b) hereof, deliver to Purchaser at the
         Closing any insurance proceeds actually received by Seller attributable
         to the Property from such casualty (except for proceeds previously used
         to repair the Property) together with any deductible under Seller's
         insurance policy and assign to Purchaser all of Seller's right, title
         and interest in and to any claims which Seller may have under the
         insurance policies covering the Property, and there shall be no
         reduction in the Purchase Price. In the event less than a substantial
         portion of the Property shall be damaged or destroyed by fire or other
         casualty prior to Closing, then the parties shall proceed in accordance
         with the second sentence in this Section 9.2(a).

                  (b) For the purposes of Section 9.2(a), a "substantial
         portion" of the Property shall be deemed to be any portion of the
         Property with either a fair market value or replacement cost in an
         amount equal to or greater than One Hundred Eighteen Thousand Two
         Hundred and No/100 Dollars ($118,200.00). Notwithstanding anything in
         Section 9.2(a) to the

                                      -20-


<PAGE>



         contrary, if Purchaser has not timely elected to terminate in
         accordance with Section 9.2(a), and if the proceeds payable with
         respect to the Property as a result of casualty exceed the Purchase
         Price for the Property, the portion of such proceeds in excess of the
         Purchase Price shall be paid to Seller (in addition to the Purchase
         Price) at the Closing. The foregoing provision shall survive the
         Closing.

                                   ARTICLE X.

                              DEFAULTS AND REMEDIES

         10.1 Default by Purchaser. If Seller shall not be in default hereunder
and Purchaser refuses or fails to consummate the Closing under this Contract for
reasons other than due to a termination permitted hereunder or other than due to
a failure of a condition precedent to Purchaser's obligation to close as set
forth in Section 7.1 hereof, Seller shall, as its sole and exclusive remedy,
terminate this Contract in which event neither party shall have any further
rights, duties, or obligations hereunder except for provisions of this Contract
which expressly survive the termination hereof, and Seller shall be entitled to
receive and retain the Earnest Money Deposit as liquidated damages (Seller and
Purchaser hereby acknowledging that the amount of damages in the event of
Purchaser's default is difficult or impossible to ascertain but that such amount
is a fair estimate of such damage). Notwithstanding anything contained in this
section to the contrary, in the event of any default by Purchaser of any
indemnity under this Contract which survives the Closing or termination of this
Contract, Seller shall have any and all rights and remedies available at law or
in equity by reason of such default, excluding, however, any punitive,
speculative or consequential damages or damages for loss of opportunity or lost
profit. Except as otherwise provided in this Section 10.1, in no event shall
Purchaser be liable to Seller for any damages, including, without limitation,
any actual, punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit.

         10.2 Default by Seller. If Purchaser shall not be in default hereunder
and if Seller refuses or fails to consummate the Closing under this Contract
other than due to a termination permitted hereunder or a failure of a condition
precedent to Seller's obligation to close as set forth in Section 7.2 hereof,
Purchaser may, at Purchaser's sole option, as its sole and exclusive remedies,
either (a) terminate this Contract in which event neither party shall have any
further rights, duties or obligations hereunder except for provisions of this
Contract which expressly survive the termination hereof, and Purchaser shall be
entitled to a refund of the Earnest Money Deposit, or (b) enforce specific
performance of this Contract. Notwithstanding anything contained in this Section
to the contrary, in the event of (x) (i) any breach by Seller of any
representation or warranty under this Contract which survives the Closing, and
(ii) the Closing occurs under this Contract or (y) any breach by Seller of any
indemnity under this Contract which survives the Closing or termination of this
Contract, in either the case of (x) or (y), Purchaser shall have any rights and
remedies available at law or in equity by reason of such breach, excluding,
however, any punitive, speculative or consequential damages or damages for loss
of opportunity or lost profit. Except as otherwise provided in this Section
10.2, in no event shall Seller be liable to Purchaser for any damages,
including, without limitation, any actual, punitive, speculative or
consequential damages or damages for loss of opportunity or lost profit.

         10.3 Attorneys' Fees. If it shall be necessary for either Purchaser or
Seller to employ an attorney to enforce its rights pursuant to this Contract,
the non-prevailing party shall reimburse the prevailing party for its reasonable
attorneys' fees.

                                   ARTICLE XI.

                              BROKERAGE COMMISSIONS

         11.1 Brokerage Commission. Seller and Purchaser represent each to the
other that each has had no dealings with any broker, finder or other party
concerning the purchase of the Property except Breunig Commercial Management,
Inc. ( the "Broker"). Seller shall be solely responsible for the payment of any
commission to Broker pursuant to a separate written agreement. Seller represents
and warrants to Purchaser that Broker's right to receive a commission or any
other amount with respect to this Contract or the Property is expressly
conditioned upon Closing the sale of the Property and Seller's receipt of the
Purchase Price under this Contract. Seller represents and warrants to Purchaser
that Broker shall have no right to receive this commission or any other amount
with respect to this Contract or the Property unless and until Closing shall be
final and fully consummated and Seller shall have received the Purchase Price as
provided in this Contract. Seller agrees to indemnify Purchaser and hold
Purchaser harmless from any loss, liability, damage, cost or expense (including,
without limitation, reasonable attorneys' fees) arising out of or paid or
incurred by Purchaser by reason of any claim to any broker's, finder's or other
fee in connection with this transaction by any party claiming by, through or
under Seller (including, without limitation, Broker). Purchaser agrees to
indemnify Seller and hold Seller harmless from any loss, liability, damage, cost
or expense (including, without limitation, reasonable attorneys' fees) arising
out of or paid or incurred by Seller by reason of any claim to any broker's,
finder's or other fee in connection with this transaction by any party claiming
by, through or under Purchaser (excluding Broker). Notwithstanding anything to
the contrary contained herein, the indemnities and other provisions set forth in
this Article XI shall survive the Closing or termination of this Contract.

         Purchaser hereby acknowledges that at the time of the execution of this
Contract, Purchaser is advised by this writing that Purchaser should have an
abstract covering the Property examined by an attorney of Purchaser's own
selection, or that Purchaser should be furnished with or obtain an owner policy
of title insurance.

                                  ARTICLE XII.

                 OPERATION OF THE PROPERTY PRIOR TO THE CLOSING

         12.1 Operation of the Property. Between June 1, 1998 and the Closing
Date, Seller shall (a) lease, operate, manage and enter into contracts with
respect to the Property, in the same manner done by Seller prior to the date
hereof (provided, however, that without the prior consent of Purchaser, which as
to (i) and (ii) shall not be unreasonably delayed, conditioned or withheld, (i)
Seller shall not enter into any Service Contract that cannot be terminated with
thirty (30) days notice or materially modify any existing Service Contracts to
be assumed by Purchaser at Closing, and (ii)

                                      -22-

after June 1, 1998, Seller shall not materially modify or terminate any existing
Tenant Lease or grant any material consents under any existing Tenant Lease
(except as otherwise required pursuant to the terms and conditions of such
Tenant Lease), or enter into any new Tenant Lease, and (iii) Seller shall not
apply any then unapplied Deposits (as reflected on the Rent Roll delivered by
Seller to Purchaser pursuant to Schedule 5.3(vii) hereof) under Tenant Leases);
and (b) advise Purchaser of the commencement of any litigation, condemnation or
other judicial or administrative proceedings affecting the Property of which
Seller has current actual knowledge.

         Notwithstanding anything to the contrary set forth in this Contract,
Purchaser acknowledges that after June 1, 1998 and prior to Closing, Seller will
enter into contracts for the completion of Tenant improvements under Tenant
Leases entered into after June 1, 1998 pursuant to the terms of Section 12.1
hereof (collectively, the "Tenant Finish Contracts"). Purchaser and Seller agree
that at Closing, Purchaser shall assume the obligations of Seller under all such
Tenant Finish Contracts including, without limitation, the obligations to pay
any costs and expenses charged with respect to construction of improvements in
the space subject to such Tenant Leases. At Closing, Purchaser shall execute and
deliver to the Seller an Assignment, Assumption and Indemnity Agreement in the
form attached hereto as Exhibit H and made a part hereof for all purposes.

                                  ARTICLE XIII.

construing the terms of this Contract.

         13.7 Survival. Except as otherwise expressly provided herein, no

of this Section 13.16 shall survive the Closing for a period of one year.

         13.17 Disclosure: Audit Right.

                  (a) Public Disclosure of Contract. Seller acknowledges that
         Purchaser and/or its general partner, Beacon Capital Partners, Inc.,
         have made and intend in the future to make private and/or public
         securities offerings which are or may be subject to regulation by the
         Securities and Exchange Commission ("SEC"), and that the regulations of
         the SEC may require that Purchaser disclose the existence of this
         Contract and the contents of some or all of the documents and materials
         delivered by Seller. Accordingly and notwithstanding anything to the
         contrary contained in their Contract, Seller expressly consents to the
         disclosure of the terms and conditions of this transaction, this
         Contract itself, and terms of any document or materials which Purchaser
         in good faith believes should be disclosed in connection with
         fulfillment of its disclosure requirements under SEC regulations. In
         addition, Purchaser shall have the right to issue press releases
         announcing this transaction at any time after the expiration of the
         Inspection Period. Seller shall be entitled to a prior review of the
         press release. The provisions of this Section 13.17(a) shall survive
         the Closing.

                  (b) Right to Audit. In order to comply with SEC regulations,
         Purchaser may need the right prior to or subsequent to Closing, to
         conduct an audit of Seller's books and records for the Property in
         conformity with applicable SEC Regulations for prior years and/or for
         Seller's period of ownership during the year in which the Closing
         occurs. Seller hereby

                                      -26-


<PAGE>



         agrees, for a period of six months after Closing, to permit Purchaser
         and Purchaser's accountants access to such books and records (including
         those maintained by Seller's management agent for the Property) and to
         cooperate with Purchaser, and to cause Seller's accountants to
         cooperate with Purchaser, at no cost to Seller, to enable such audit to
         be performed. The provisions of this Section 13.17(b) shall survive the
         Closing for a period of six months.

         remedies set forth in this Contract;

                  (d) The termination by Purchaser of this Contract pursuant to

<PAGE>



         entitles Seller to receive the Earnest Money Deposit shall terminate
         all of the other Dependent Contracts and the Earnest Money Deposit held
         under this Contract shall be promptly paid to Seller and the earnest
         money deposits held under the Dependent Contracts shall be promptly
         paid to the applicable Dependent Sellers; and

                  (f) Notwithstanding anything contained in this Section 14.1
         hereof, in the event of a termination of this Contract or any of the
         Dependent Contracts due to (x) the failure or refusal of Seller to
         consummate the Closing under this Contract (other than due to a
         termination permitted hereunder or a failure of a condition precedent
         to Seller's obligation to close or due to the default of Purchaser
         hereunder) or the failure or refusal of any of the Dependent Sellers to
         consummate the closing under any of the Dependent Contracts (other than
         due to a termination permitted thereunder or a failure of a condition
         precedent to such Dependent Seller's obligation to close or due to the
         default of Purchaser thereunder) or (y) a casualty or condemnation
         pursuant to the terms and provisions set forth in Article IX hereof,
         then at Purchaser's option, the Dependent Contracts and this Contract
         not so terminated shall not be automatically terminated and the
         closings thereunder shall occur pursuant to the terms thereof.

         14.2 Section 1031 Exchange. Purchaser acknowledges that Seller may
elect to transfer its interest in the Property pursuant to a like-kind exchange
qualifying under Section 1031 of the Internal Revenue Code of 1986, as amended.
Purchaser agrees to reasonably cooperate with Seller, subject to the limitations
of this Section 14.3, in order to enable Seller to consummate the transfer of
the Property as part of a like-kind exchange qualifying pursuant to Section
1031.

         The exchange is not to occur simultaneously with the conveyance of the
Property and, therefore, Purchaser will, upon Seller's request, cooperate with
Seller in a "delayed exchange". Pursuant to a delayed exchange, Purchaser will
acquire the Property from a third party designated by Seller who will be
contractually bound to (i) acquire replacement property designated by Seller and
(ii) transfer the designated replacement property to Seller as part of Seller's
exchange with the third party; provided, that notwithstanding that Purchaser may
acquire the Property from such third party, Properties of Floyd Road, Ltd. will
remain obligated as the Seller under this Contract, and all representations,
warranties, covenants, agreements and obligations which survive the Closing and
are binding upon the Seller hereunder shall survive and continue as
representations, warranties, covenants, agreements and obligations of Properties
of Floyd Road, Ltd.

         To accomplish Seller's goal in either case, Purchaser shall execute or
consent to such additional documents and transactions as may be reasonably
requested by Seller, including, but not limited, to any assignments of documents
or interest in the contemplated transactions, provided that (a) there shall be
no delay in the Closing Date and the consummation of the transactions
contemplated in this Contract; (b) Seller shall not be released if the exchange
fails for any reason and in such event only Seller shall remain obligated to
consummate the transaction contemplated in this Contract; (c) Seller shall
reimburse Purchaser for any and all costs reasonably incurred by Purchaser as a
result of the exchange or attempted exchange; (d) Purchaser need not assume any
additional liabilities or obligations as a result of the exchange or attempted
exchange; and (e) Seller shall not

                                      -28-

be released from any representations, warranties, covenants, agreements or
obligations hereunder as a result of the exchange or attempted exchange.

         Seller shall fully indemnify, defend and hold Purchaser harmless for,
from and against any and all liabilities, claims, damages, expenses (including,
without limitation, reasonable attorneys' fees), taxes, fees, proceedings and
causes of action of any kind or nature whatsoever arising out of, connected with
or in any manner related to such Section 1031 exchange or attempted exchange.
The provisions of the immediately preceding sentence shall survive Closing and
the transfer of title to the Property to Purchaser. Any Section 1031 exchange
shall be consummated in such a manner that Purchaser shall not be required to
acquire title to any real or personal property other than the Property, or incur
any liability, in connection therewith.

         IN WITNESS WHEREOF, the undersigned have executed this Contract
effective as of the Effective Date.
