On July 8, 1998, the Company announced, in a press released attached hereto 
as Exhibit 99.1 and incorporated herein by reference, agreements to sell in a 
private placement 1,092,051 shares of its Common Stock for an aggregate 
purchase price of $18,018,841 (the "Private Placement") to several institutional
purchasers including certain accounts managed by CRA Real Estate Securities, 
L.P. and Morgan Stanley Asset Management, Inc. The shares will not be 
registered under the Securities Act of 1933, as amended, and may not be 
offered or sold in the United States absent registration or an applicable 
exemption from registration.

The subscription agreements (which are filed as exhibits 10.7 and 10.8 
hereto) (the "Agreements") for the Private Placement include provisions for a 
purchase price adjustment on the earlier of the first business day after the 
first anniversary of the closing or the first business day after a 
Liquidating Event, as defined in the Agreement, has occurred and the average 
price of the Company's Common Stock for a 30-day period preceding such date 
is greater than $19.50 or less than $15.50 per share of Common Stock.  In the 
event the average price is less than $15.50, the Company is required to 
deliver to the purchasers cash in an amount equal to (i) the difference 
between $15.50 and the average price, multiplied by (ii) the number of shares 
of Common Stock purchased.  In the event the average price is greater than 
$19.50, the purchasers are required to deliver to the Company the number of 
shares of Common Stock equal to (i) the difference between the average price 
and $19.50, divided by (ii) the average price, multiplied by (iii) the number 
of shares of Common Stock purchased in the Private Placement. The Company has 
granted certain registration rights to the purchasers pursuant to the 
Registration Rights Agreements attached hereto as Exhibits 10.5 and 10.6. The

- -    On July 9, 1998, the Company issued 1,092,051 shares of Common Stock at
     $16.50 per share to various institutional investors in a Private Placement
     (the "Private Placement").  The net proceeds from the Private Placement

     interest ("OP Units").

All of the above acquisition transactions were accounted for using the purchase

management's opinion, all adjustments consisting of normal recurring adjustments

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 statement is free of 
material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statement.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as, evaluating the overall 
financial statement presentation. We believe that our audit provides a 
reasonable basis for our opinion.

The combined statement of revenue and certain expenses was prepared for the

                             THE GALESI PROPERTIES

           NOTES TO THE COMBINED STATEMENT OF REVENUE AND CERTAIN EXPENSES

                       FOR THE YEAR ENDED DECEMBER 31, 1997

1.   BASIS OF PRESENTATION:

The combined statement of revenue and certain expenses reflects the combined 
operations of the Columbia properties and the Northeastern Industrial Park 
properties (collectively the "Properties").  The Properties consist of the 
Columbia properties (7 buildings) located in Albany, NY, and three industrial 
buildings located in the Northeastern Industrial Park, which is located in 
Guilderland, NY.  The Properties have an aggregate net rentable area of 
approximately 780,357 square feet and are 94% leased as of December 31, 1997.

The Properties will be acquired by American Real Estate Investment Corporation 
(the "Company") under agreements with Columbia Executive Assoc. I, II, III, V, 
VI, VII, VIII, Northeastern Industrial Park, Inc., and Guilderland Ventures, 
Inc. (all affiliates of the Galesi Group).  This combined statement of 
revenue and certain expenses is to be included in the Company's current 
report on Form 8-K/A, as the above described transaction has been deemed 
significant pursuant to the rules and regulations of the Securities and 
Exchange Commission.

The accounting records of the Properties are maintained on an accrual basis. 
Adjusting entries have been made to present the accompanying financial 
statement in accordance with generally accepted accounting principles.  The 
accompanying financial statement excludes certain expenses such as interest, 
depreciation and amortization, and other costs not directly related to the 
future operations of the Properties in conformity with Rule 3-14 of the 
Securities and Exchange Commission.

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

The statement of revenue and certain expenses for the three months ended 
March 31, 1998 is unaudited; however, in the opinion of management, all 
adjustments (consisting solely of normal recurring adjustments) necessary for 
the fair presentation of the statement of revenue and certain expenses for 
the interim period have been included.  The results of the interim periods 
are not necessarily indicative of the results for the full year.

2.   OPERATING LEASES:

Minimum rent presented for the year ended December 31, 1997, includes 
straight-line adjustments for rental revenue increases in accordance with 
generally accepted accounting principles.  The aggregate rental revenue 
increase resulting from the straight-line adjustment for the year ended 
December 31, 1997 was $64,000.

             NOTES TO STATEMENT OF REVENUE AND CERTAIN EXPENSES

                                DECEMBER 31, 1997



1.   BASIS OF PRESENTATION:

The statement of revenue and certain expenses reflect the operations of the 
following properties in the Fed One Industrial Portfolio (the "Portfolio"):

<TABLE>

                  Property                                Location
                  --------                                --------
           <S>                                         <C>
           16725 Square Drive                          Marysville, Ohio
           1030/1037 S. Edgwood Drive                  Urbana, Ohio
           3530 East Pike                              Zanesville, Ohio
</TABLE>

The Portfolio is expected to be acquired by American Real Estate Investment 
Corporation (the "Company") from Fed One of Dayton in June 1998. The 
Portfolio has an aggregate net rentable area of approximately 633,500 square 
feet (100% leased as of December 31, 1997).  This statement of revenue and 
certain expenses is to be included in the Company's current report on Form 
8-K/A, as the above described transaction has been deemed significant 
pursuant to the rules and regulations of the Securities and Exchange 
Commission.

The accounting records of the Portfolio are maintained on a modified cash 
basis. Adjusting entries have been made to present the accompanying financial 
statements in accordance with generally accepted accounting principles.  The 
accompanying financial statements exclude certain expenses such as interest, 
depreciation and amortization, professional fees, and other costs not 
directly related to the future operations of the Portfolio.

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

The statement of revenue and certain expenses for the three months ended 
March 31, 1998 is unaudited; however, in the opinion of management, all 
adjustments (consisting solely of normal recurring adjustments) necessary for 
the fair presentation of the statement of revenue and certain expenses for 
the interim period have been included.  The results of the interim periods 
are not necessarily indicative of the results for the full year.

<PAGE>


         2.       EARNEST MONEY

                  Within three (3) business days after the execution of this
Agreement by Contributor and Acquiror, Acquiror shall deliver to TitleServNY
located in New York, New York ("Escrowee") a check payable to Escrowee or wire
transferred federal funds in the amount of One Hundred Thousand and 00/100
Dollars ($100,000.00) (the "Earnest Money"). The Earnest Money, together with
any and all interest earned thereon (net of any investment costs), shall
hereinafter be referred to as the "Earnest Money." The Earnest Money shall be
invested and applied in accordance with the terms and conditions of the Escrow
Agreement attached hereto as Exhibit E. The Escrow Agreement shall be executed
and delivered by Contributor, Acquiror and Escrowee contemporaneously with the
execution and delivery of this Agreement. Upon the Closing, the Earnest Money
shall be returned to Acquiror.

         3.       CONTRIBUTION CONSIDERATION; OP UNITS; OTHER AGREEMENTS

                  A. General. Acquiror's sole general partner is American Real
Estate Investment Corporation, a Maryland corporation (the "REIT"). The REIT is
a real estate investment trust whose common stock is traded on the American
Stock Exchange (the "AMEX").

                  B. Contribution Consideration. The aggregate consideration to
be paid to Contributor by Acquiror for the Properties (the "Contribution
Consideration") shall consist of that number (the "Total OP Unit Amount") of OP
Units (as defined below) equal to: (i) 565,048 OP Units; minus (ii) the amount
of OP Units equal to (a) the aggregate amount of any prorations described in
Section 6C ("Prorations") and credited, as of the Closing Date, to Acquiror
divided by (b) $16.50; plus (iii) the amount of OP Units equal to (x) the
aggregate amount of any Prorations credited, as of the Closing Date, to
Contributor divided by (y) $16.50. If the calculation of the Contribution
Consideration in accordance with the foregoing provision would result in a
fraction of an OP Unit being delivered to Contributor, then such fraction shall
be rounded to the nearest whole number. The Properties are to be contributed to
Acquiror subject to those corresponding items of indebtedness of Contributor set
forth on Exhibit F attached hereto outstanding as of the Closing Date (as
defined below) (the "Existing Indebtedness"), in order to obtain a release from
the lien of such mortgage loans, which will either be assumed, refinanced or
paid off by Acquiror immediately following the Closing.

                  C. Issuance of OP Units. Units of limited partnership interest
in Acquiror (the "OP Units") shall be issued and delivered in the names of and
for distribution to those recipients set forth in Exhibit G attached hereto (the
"OP Unit Recipients"). After the first anniversary of the Closing the OP Units
shall be convertible at any time or from time to time for shares ("Conversion
Shares") of the common stock, par value $.001 per share, of the REIT ("Stock")
on a one-for-one basis, or for cash as provided in and subject to the conditions
and restrictions contained in the Acquiror's Amended and Restated Agreement of
Limited Partnership dated as of December 12, 1997 (the "Partnership Agreement")
provided, however, that notwithstanding the foregoing, the OP Units (together
with the OP Units issued pursuant to the Columbia Contribution Agreement) may
not be converted into Conversion Shares that in the aggregate represent more
than 19.9% of the total number of shares of Stock that are issued and
outstanding on the date on which the OP Units are issued to the OP Unit
Recipients until and unless the requisite approval from the REIT's stockholders
is obtained prior to such conversion. Acquiror agrees that it will use its
commercially reasonable efforts to cause the REIT to seek such stockholder
approval, including presenting the issue, with management's endorsement, to the
REIT's stockholders at the next annual or special meeting of stockholders
following the Closing, and to present the issue at the next subsequent meeting
if the necessary stockholder approval is not obtained.

                  D. Transfer Restrictions. Each OP Unit Recipient, by his
execution and delivery of 


<PAGE>


this Agreement, agrees that he may only sell, transfer, assign, pledge or
encumber, or otherwise convey, any or all of the OP Units issued and delivered
to him in connection with this transaction and, if applicable, any Conversion
Shares (any of the foregoing, a "Transfer") in strict compliance with this
Agreement, the Partnership Agreement, the charter documents of the REIT, the
registration and other provisions of the Securities Act of 1933 as amended and
the rules and regulations promulgated thereunder (the "Securities Act"), any
state securities laws, and the rules of the AMEX, in each case as may be
applicable (collectively, the "Transfer Requirements"). Each OP Unit Recipient
shall have the registration rights with respect to the Conversion Shares
issuable in respect of its OP Units set forth in the OP Unit Recipient Agreement
(as defined below). The provisions of this paragraph shall survive the Closing.

                  E. Lock-Up Period. Each OP Unit Recipient agrees that for a
period of twelve (12) months following the Closing (the "Lock-Up Period") he
shall not, nor shall he seek to, in any way or to any extent, directly or
indirectly exchange or convert (pursuant to the Partnership Agreement or
otherwise), offer, sell, offer or contract to sell, transfer, assign, grant any
option for the sale of, pledge (without Acquiror's consent which will not be
unreasonably withheld, and except for pledges to those pledgees listed in
Schedule 3E) or encumber, or otherwise transfer, convey, or dispose of, any or
all of the OP Units delivered to the OP Unit Recipient at the Closing or the
Conversion Shares in respect thereof; provided that transfers may be made,
subject to the restrictions hereof and under the Partnership Agreement, to
Permitted Transferees (as defined below) who shall remain subject to the
restrictions hereunder. In addition, each OP Unit Recipient further agrees that
following the expiration of the Lock-Up Period, not more than twenty-five
percent (25%) of the OP Units delivered to such OP Unit Recipient at the Closing
or Conversion Shares in respect thereof may be sold in the three-month period
following the initial Lock-Up Period, and an additional twenty-five percent
(25%) of such OP Units and Conversion Shares may be sold in each three-month
period thereafter (so that all OP Units and Conversion Shares may be sold after
the second (2nd) anniversary of the Closing Date). The term "Permitted
Transferee" with respect to any OP Unit Recipient shall mean any other OP Unit
Recipient or an individual who directly or indirectly, as a stockholder, member
or partner, owns such OP Unit Recipient and with respect to such individual,
such individual's spouse; a parent or lineal descendant (including an adopted
child) of a parent, or the spouse of a lineal descendant of a parent; a trustee,
guardian or custodian for, or an executor, administrator or other legal
representative of the estate of, any such recipient or individual, or a trustee,
guardian or custodian for a Permitted Transferee of such recipient; the trustee
of a trust (including a voting trust) for the benefit of such recipient; and a
corporation, partnership or other entity of which such recipient and/or
Permitted Transferees of such recipient or individual are the beneficial owners
of a majority in voting power of the equity; but only in each of the foregoing
cases, who (a) is an Accredited Investor (as defined in Rule 501 under the
Securities Act); and (b) agrees in writing in an instrument reasonably
acceptable to Acquiror to be bound by the restrictions on transfer of the OP
Units and Conversion Shares contained in this Agreement and by the obligations
contained in the indemnification provisions contained in Section 14 of this
Agreement. The provisions of this paragraph shall survive the Closing. Each OP
Unit Recipient shall execute and deliver to Acquiror at Closing a letter to the
effect of the foregoing, in form and substance reasonably satisfactory to
Acquiror.

                  F. Right of First Refusal/First Offer on Sale of OP Units.
Each OP Unit Recipient agrees that Acquiror shall have a right of first refusal
and a right of first offer with respect to OP Units that such OP Unit Recipient
seeks to sell, as provided in an agreement to be delivered by each OP Unit
Recipient at Closing substantially in the form of Exhibit H attached hereto (the
"OP Unit Recipient Agreement").

                  G. Right of First Refusal/First Offer on Sale of Buildings.

                        (i) From and after the Closing Date and continuing up to
         and including the fifth (5th) anniversary thereof, Acquiror shall have
         a continuing right of first refusal to (1) purchase any building(s)
         owned by Contributor and/or any of the OP Unit Recipients
         (collectively, "Owner") 


<PAGE>


         and located at the Northeastern Industrial Park, and (2) purchase or
         develop as a joint venture partner the approximately 400 acres of land
         adjoining the Properties, as follows: In the event Owner receives a
         bona fide third party offer to (1) purchase (whether by transfer of
         fee simple interest, a ground lease, sale of an interest in Owner, an
         installment sale, or otherwise) one or more buildings and related land
         and facilities located at the Northeastern Industrial Park (the "First
         Refusal Buildings") or, subject to Section 3G(iii) below, (2) purchase
         or develop as a partner with Owner or any affiliate of Owner all or
         any portion of the approximately 400 acres of land adjoining the
         Properties or any building to be built thereon (the "First Refusal
         Land"), and Owner desires to accept such offer, Owner shall provide
         written notice to Acquiror within ten (10) days after Owner's receipt
         of such offer, including a copy of the offer and specifying the
         purchase price, terms of payment, identity of the First Refusal
         Building(s) or First Refusal Land and other material terms and
         conditions of such third party offer. Acquiror or its nominee shall be
         entitled for a period of fifteen (15) days after the date of receipt
         of such notice of a third party offer to exercise its right to
         purchase such First Refusal Building(s) or to purchase or develop as a
         partner with Owner or any affiliate of Owner, as the case may be, the
         First Refusal Land in accordance with the terms and conditions
         specified in the offer as set forth in Owner's written notice to
         Acquiror. Acquiror shall not have the right of first refusal for less
         than all of the First Refusal Building(s) identified in a third party
         offer for two or more of the First Refusal Building(s) or for less
         than all of the First Refusal Land identified in a third party offer
         unless such third party offeror shall have alternative rights to
         purchase less than all of the First Refusal Building(s) or to purchase
         or develop as a partner with Owner, as the case may be, less than all
         of the First Refusal Land identified in the offer at prices and
         pursuant to terms set forth in the offer, in which case, Acquiror's
         right of first refusal shall correspond to the third party offeror's
         alternative rights. Any elimination of First Refusal Buildings or any
         First Refusal Land from the original offer or addition of one or more
         First Refusal Buildings or more First Refusal Land to the original
         offer shall constitute a new offer for purposes of this paragraph, for
         which Acquiror shall have the corresponding right of first refusal,
         provided that the terms for such elimination or addition were not part
         of the original offer submitted to Acquiror for right of first refusal
         consideration. If Acquiror exercises its right to purchase or develop
         with Owner or any affiliate of Owner, as the case may be, the interest
         so offered, Owner and Acquiror shall consummate the purchase and sale
         or joint venture, as the case may be, within a period of ninety (90)
         days after the date Acquiror provides written notice to Owner
         exercising its right to purchase or develop with Owner or any
         affiliate of Owner, as the case may be, unless such closing is delayed
         for reasons beyond the reasonable control of the parties. In the event
         Acquiror fails to exercise its right of first refusal as set forth in
         this paragraph, Owner shall be free to sell the First Refusal
         Building(s) to, or to sell or develop, as the case may be, the First
         Refusal Land to or with, such third party offeror pursuant to the
         terms and conditions of the offer; provided, however, that in the
         event a binding contract of sale for such First Refusal Building(s) or
         a binding contract of sale or joint venture agreement, as the case may
         be, for such First Refusal Land is not executed between Owner and such
         third party offeror within 180 days after the expiration of Acquiror's
         fifteen-day right of first refusal period, or the aggregate purchase
         price or consideration is reduced by 3% or more or the other terms and
         conditions of such third party offer are modified in any other
         material respect, then Acquiror shall again have its right of first
         refusal to acquire such First Refusal Building(s) or First Refusal
         Land as set forth in this paragraph, and Owner and Acquiror shall
         again comply with the requirements hereof. For purposes of this
         paragraph, a bona fide third party offer shall include, without
         limitation an executed letter of intent so long as such letter of
         intent specifies the purchase price, terms of payment, identity of the
         First Refusal Building(s) or First Refusal Land and other material
         terms and conditions.

                       (ii) From and after the Closing Date and continuing up to
         and including the fifth (5th) anniversary thereof, Acquiror shall have
         a continuing right of first offer to (1) purchase any building(s) owned
         by Owner and located at the Northeastern Industrial Park, and (2)
         purchase 


<PAGE>


         or develop as a joint venture partner the approximately 400 acres of
         land adjoining the Properties, as follows: In the event Owner desires
         to (1) sell or seek to sell (whether by transfer of fee simple
         interest, a ground lease, sale of an interest in Owner, an installment
         sale, or otherwise) one or more buildings and related land and
         facilities located at the Northeastern Industrial Park (the "First
         Offer Buildings") or, subject to Section 3G(iii) below, (2) sell or
         seek to sell, or develop with a partner all or any portion of the
         approximately 400 acres of land adjoining the Properties or any
         building to be built thereon (the "First Offer Land"), Owner shall
         provide written notice to Acquiror specifying the purchase price,
         terms of payment, identity of the First Offer Building(s) or First
         Offer Land and other material terms and conditions of the offer or
         sale (the "Sale Notice"). Acquiror or its nominee shall have the
         option (the "Purchase Option"), to be exercised by written notice
         given to Owner within thirty (30) days after Acquiror's receipt of the
         Sale Notice (the "Exercise Period"), to purchase the First Offer
         Buildings from Owner, or to purchase or develop as a partner with
         Owner, as the case may be, the First Offer Land on the terms specified
         in the Sale Notice. If Acquiror exercises its Purchase Option, Owner
         and Acquiror shall consummate the purchase and sale or joint venture,
         as the case may be, within a period of ninety (90) days after the date
         Acquiror provides written notice to Owner exercising its right to
         purchase or develop with Owner or any affiliate of Owner, as the case
         may be, unless such closing is delayed for reasons beyond the
         reasonable control of the parties. In the event Acquiror fails to
         exercise its Purchase Option as set forth in this paragraph, Owner
         shall be free to sell the First Offer Building(s) to, or to sell or
         develop, as the case may, the First Offer Land to or with, third
         parties pursuant to the terms and conditions of the offer to Acquiror;
         provided, however, that in the event a binding contract of sale for
         such First Offer Building(s) or a binding contract of sale, loan
         agreement or joint venture agreement, as the case may be, for such
         First Offer Land is not executed between Owner and such third party
         offeror within 180 days after the expiration of the Exercise Period,
         or the aggregate purchase price or consideration is reduced by 3% or
         more or the other terms and conditions of such third party offer are
         modified in any other material respect, then Acquiror shall again have
         its right of first offer to acquire such First Offer Building(s) or
         First Offer Land as set forth in this paragraph, and Owner and
         Acquiror shall again comply with the requirements hereof.

                      (iii) Notwithstanding the foregoing right of first refusal
         and right of first offer, such rights shall not apply to First Refusal
         Land or First Offer Land in instances where Owner either receives bona
         fide offers from, or proposes to sell to, potential purchasers or
         potential developers who would also be, or whose affiliate would be,
         the tenant in the building(s) proposed to be built on such land.

                       (iv) At Closing, Contributor and Acquiror shall execute
         and record against the other properties owned by Owner at the
         Northeastern Industrial Park, a memorandum of Acquiror's right of first
         refusal and first offer set forth in the foregoing paragraph. Such
         memorandum shall expire on the date (the "Expiration Date") that is
         sixty (60) days after the fifth (5) anniversary of the Closing Date.
         Contemporaneous with the execution and delivery of such memorandum,
         Acquiror shall execute and deliver into escrow with Steven K. Porter,
         attorney for Contributor, an agreement in form and substance
         satisfactory to Contributor and Acquiror terminating of record the
         memorandum referred to above, which agreement Mr. Porter shall be
         authorized to release from escrow and record thirty (30) days after the
         Expiration Date. The terms and conditions of this paragraph shall
         survive the Closing.

                  H. Tax Matters. During the period commencing on the Closing
Date and expiring on the earlier to occur of (i) the seventh (7th) anniversary
of the Closing Date or (ii) the sale or conversion by the OP Unit Recipients of
OP Units representing in the aggregate 70% of all OP Units delivered to them at
the Closing, Acquiror shall not sell or make any other voluntary disposition
(other than through a deed in lieu of foreclosure, a foreclosure action, or an
act of eminent domain) of any of the Properties in a 


<PAGE>


transaction that causes gain recognition under Sections 704(c) or 752 (or any
other section) of the Internal Revenue Code of 1986, as amended (the "Code") for
Contributor without the consent of Contributor. Thereafter, Acquiror shall use
all commercially reasonable efforts in disposing of any of the Properties during
the period expiring on the earlier to occur of (i) the tenth (10th) anniversary
of the Closing Date or (ii) the sale or conversion by the OP Unit Recipients of
OP Units representing in the aggregate 70% of all OP Units delivered to them at
the Closing, to structure such disposition as a transaction that will qualify
for non-recognition of gain under the Code, whether by means of an exchange
contemplated under Code Sections 351, 354, 355, 368, 721, 1031, 1033 or
otherwise, in which not more than 10% of the built-in gain associated with such
Property is required to be recognized by the OP Unit Recipients. Notwithstanding
the foregoing, in the event of catastrophic damage to any or all of the
Properties by an act of God (e.g., hurricane or tornado), Acquiror shall have
the right to sell any or all of the Properties affected thereby without regard
to the foregoing. Pursuant to Section 5.4 of the Partnership Agreement, Acquiror
shall elect to use the "traditional method" set forth in Regulation Section
1.704-3(b) with respect to the Properties.

                  I. Board Seat. Acquiror shall take all such actions necessary
to cause the nomination of Francesco Galesi for election to the Board of
Directors of the REIT, with an initial term of not less than two (2) years nor
more than three (3) years, at the REIT's next annual or special meeting of the
REIT's stockholders, such nominee to take office effective upon such election.

                  J. Allocation of Contribution Consideration. Prior to the
Closing and if requested by Acquiror, Acquiror and Contributor shall use
commercially reasonable efforts to agree in writing upon the allocation of the
Contribution Consideration among the Land, the Improvements and the tangible
Personal Property.

                  K. Further Assurances. Each party hereto will execute such
further documents and instruments and take such further actions as may be
reasonably requested by one or more of the others to consummate the transactions
contemplated hereby, to vest Acquiror with full right, title and interest in and
to the Properties or to effect the other purposes of this Agreement. In
addition, Contributor will use all commercially reasonable efforts to cause,
prior to the Closing, the recordation described in Section 6B(i)(n).

                  L. Notification if Representations and Warranties Untrue.
During the Inspection Period (as defined below), Acquiror shall notify
Contributor upon discovery that any representation or warranty of Contributor
contained in this Agreement is untrue or incorrect, and Contributor shall notify
Acquiror upon discovery that any representation or warranty of Acquiror
contained in this Agreement is untrue or incorrect.

         4.       OPERATION OF PROPERTIES THROUGH CLOSING

                  Through the Closing Date, Contributor shall:

                  A. Except as otherwise provided for in this Agreement, manage
and operate the Properties only in and shall not take any actions except in
accordance with Contributor's usual and ordinary course of business consistent
with past practices and keep the Land, the Improvements and the tangible
Personal Property in their current condition and repair, ordinary wear and tear
excepted.

                  B. Not extend or otherwise renew any Lease or Service Contract
without the prior written consent of Acquiror, which consent shall not be
unreasonably withheld.

                  C. Not cancel, modify or amend any Lease or Service Contact or
institute any rent increases without the prior written consent of Acquiror,
which consent shall not be unreasonably withheld.


<PAGE>


                  D. Not enter into any new Lease or new Service Contract
without the prior written consent of Acquiror, which consent shall not be
unreasonably withheld.

                  E. Neither take any action nor omit to take any action that
would render or allow title to the Properties to be nonconforming to the
requirements of this Agreement.

                  F. Provide Acquiror, upon reasonable advance notice, with such
access to the Properties as is reasonably necessary for it to inspect same to
assure that Contributor is complying with the requirements of this Section 4.

                  G. Promptly deliver to Acquiror copies of any operating
statements for the Properties that come into the possession or control of
Contributor for any period(s) including the period between the date of this
Agreement and the Closing Date.

                  H. Not sell, lease, grant any security interest in, pledge,
encumber, dispose of, finance or refinance any indebtedness in respect of, any
of the Properties without the prior written consent of Acquiror, which consent
shall not be unreasonably withheld.

         5.       STATUS OF TITLE TO PROPERTIES

                  A. State of Title. Contributor shall convey the Properties to
Acquiror or Acquiror's designee subsidiary by bargain and sale deeds without
covenants against grantor's acts in recordable form (the "Deeds"), and title to
the Properties shall be free and clear of all liens and encumbrances and shall
be subject only to: (i) those covenants, conditions and restrictions of record
which are reviewed and approved by Acquiror within the Inspection Period (as
defined below), (ii) rights of tenants under the Leases, as tenants only, (iii)
general real estate taxes for the year in which the Closing occurs and
subsequent years, not yet delinquent and (iv) those certain mortgages securing
payment of the Existing Indebtedness and more particularly described in Exhibit
I attached to this Agreement (the "Existing Mortgages") (the above enumerated
exceptions being hereinafter collectively referred to as the "Permitted
Exceptions").

                  B. Preliminary Evidence of Title. As specified below,
Contributor shall furnish Acquiror with or Acquiror shall obtain at Acquiror's
expense the following documents to evidence the condition of Contributor's title
to the Properties:

                        (i) Acquiror shall obtain for each of the Properties, at
         Acquiror's expense, a commitment (the "Title Commitment") for an ALTA
         1992 Owner's Title Insurance Policy proposing to insure Acquiror or
         Acquiror's designee and committing to insure title to the Properties in
         such amounts as Acquiror deems appropriate, issued through a title
         insurer to be selected by Acquiror (the "Title Insurer"), and
         irrevocable for at least six (6) months. The Title Commitment shall
         show fee simple title to the Properties vested in Contributor. The
         Owner's Title Insurance Policy to be issued to Acquiror at the Closing
         pursuant to the corresponding Title Commitment shall be at regular
         rates and contain an extended coverage endorsement over the so-called
         general or standard exceptions that are a part of the printed form of
         the policy, an ALTA Form 103.7 access endorsement, coverage insuring
         any easements for utilities servicing the Properties that do not
         connect to the Properties from a public street, and such other
         endorsements as counsel for Acquiror shall reasonably deem appropriate.

                       (ii) Within fifteen (15) days after the date of this
         Agreement, Contributor shall furnish to Acquiror, at Acquiror's
         expense, written results of searches (the "UCC Searches") conducted by
         a private service reasonably acceptable to Acquiror of the records of
         the County Recorder of the County and Secretary of State of the State
         in which the Properties are located for 


<PAGE>


         Uniform Commercial Code Financing Statements, tax liens and the like
         in the name of Contributor, the OP Unit Recipients, the Properties and
         any other name or location reasonably requested by Acquiror.

                      (iii) Acquiror shall obtain, at Acquiror's expense, a
         current "as-built" plat of survey (the "Survey") for each of the
         Properties dated after the date of this Agreement, certified to
         Acquiror, the REIT and the Title Insurer (and such other persons or
         entities as Acquiror may designate) by a surveyor registered in the
         State in which the Properties are located as having been prepared (i)
         in accordance with the "Minimum Standard Detail Requirements for
         ALTA/ACSM Land Title Surveys," jointly established and adopted by the
         American Land Title Association ("ALTA") and the American Congress on
         Surveying and Mapping ("ACSM") in 1992, and including items 1 through 5
         (excluding for Table A5 any information with respect to elevations),
         6-11 and 13 of Table A thereof, and (ii) pursuant to the Accuracy
         Standards (as adopted by ALTA and ACSM and in effect on the date of
         such certification) of an "Urban" Survey (as defined therein). Each
         Survey shall also contain the surveyor's certification that, among
         other things, the Properties are not located in any area designated by
         any governmental agency or authority as being a flood-prone or
         flood-risk area (whether pursuant to the Flood Disaster Act of 1973, as
         amended, or otherwise), and that the requirements of the National Flood
         Insurance Program are not applicable to the Properties.

                  C. Title Defects. If the Title Commitment, the UCC Searches or
any Survey (or any revision or update of any of them) discloses exceptions to
title other than Permitted Exceptions or any other title or survey matter which
does not conform to the requirements of this Agreement, Acquiror shall so notify
Contributor and Contributor shall have fifteen (15) days after the date of
Contributor's receipt of such notice to have each such unpermitted exception to
title removed or to correct each such other matter, in each case to the
reasonable satisfaction of Acquiror. If within the time specified Contributor
fails to have each such unpermitted exception removed or to correct each such
other matter as aforesaid, Acquiror may, at its option, which option must be
selected by Acquiror within ten (10) days after the expiration of Contributor's
fifteen (15) day cure period described above, either (i) terminate this
Agreement upon written notice to Contributor and immediately receive from
Escrowee the Earnest Money, in which event this Agreement, without further
action of the partes, shall become null and void and neither party shall have
any further rights or obligations under this Agreement, except with respect to
the indemnities contained in Sections 12 and 15B (the "Surviving Indemnities")
or (ii) elect to accept title to the Properties as it then is with the right to
deduct from the Purchase Price a sum equal to the amount required to discharge
liens or encumbrances of a definite or ascertainable amount. If Acquiror fails
to make either such election, and elects not to pursue its other rights and
remedies as aforesaid, Acquiror shall be deemed to have elected option (i)
above.

         6.       CLOSING

                  A. Closing Date. The closing contemplated by this Agreement
(the "Closing") shall occur at the offices of Rogers & Wells, 200 Park Avenue,
New York, New York 10166, on the basis of a "New York Style" closing at 10:00
a.m. on (i) the earlier to occur of the fifteenth (15th) day after the
expiration of the Inspection Period and the fifth (5th) business day after all
conditions precedent to the respective obligations of the parties have been
satisfied or waived, (ii) such earlier date as the Acquiror may elect, provided
that reasonable prior notice is given to Contributor, or (iii) such other time
and at such other place as Contributor and Acquiror shall agree upon in writing,

Columbia Contribution Agreement. The "Closing Date" shall be the date of the
Closing.

                  satisfactory to Acquiror, of those Service Contracts that

                  being assigned pursuant to the Assignment of Service Contracts
                  (the "Service Contracts Notices");

                           (p) a reciprocal easement and operating agreement
                  between Acquiror and Contributor, in form and substance
                  reasonably satisfactory to Acquiror and Contributor, to be
                  duly executed by Contributor;

                           (q) a fully executed lease with Distribution
                  Unlimited Inc. in the form attached as Exhibit J to this
                  Agreement; and

                           (r) all other necessary or appropriate documents
                  reasonably required by Acquiror in order to consummate the

                       (ii) Acquiror. Not less than five (5) business days prior
         to the Closing Date, Acquiror shall deliver to Contributor a copy of

<PAGE>


                  Unit Recipient as an additional limited partner of the

                           (c)      the Service Contracts Notices;

                  between Acquiror and Contributor, in form and substance
                  reasonably satisfactory to Acquiror and Contributor, to be
                  duly executed by Acquiror; and

                           (e) all other necessary or appropriate documents
                  reasonably required by Contributor in order to consummate the
                  transaction contemplated hereby.

                      (iii) Form. Except to the extent attached to this
         Agreement, all documents and instruments required hereby shall be in
         form and substance reasonably acceptable to Contributor and Acquiror.

                  C.       Closing Prorations and Adjustments.

                        (i) A statement of prorations and adjustments shall be
         prepared by Acquiror in conformity with the provisions of this
         Agreement and submitted to Contributor for review not less than three
         (3) business days prior to the Closing Date. For purposes of
         prorations, Acquiror shall be deemed the owner of the Properties on the
         Closing Date. In addition to prorations and adjustments that may
         otherwise be provided for in this Agreement, the following items are to
         be prorated or adjusted (as the case requires) as of the Closing Date:

                           (a) the full amount of the security and other
                  deposits paid under the Leases, together with interest thereon
                  if required by law or under the Leases, shall be credited to
                  Acquiror;

                           (b) To the extent such charges are not billed
                  directly to Tenants, water, electricity, sewer, gas, telephone
                  and other utility charges shall be prorated based, to the
                  extent practicable, on final meter readings and final
                  invoices, or, in the event final readings and invoices are not
                  available, based on the most currently available billing
                  information, and reprorated upon issuance of final utility
                  bills;

                           (c) Amounts paid or payable under any Service
                  Contracts being assigned to Acquiror shall be prorated based,
                  to the extent practicable, on final invoices or, in the event
                  final invoices are not available, based on the most currently
                  available billing information, and reprorated upon issuance of
                  final invoices;

                           (d) All real estate, personal property and ad valorem
                  taxes applicable to the Properties and levied with respect to
                  calendar year 1998 shall be prorated on an accrual basis, as
                  of the Closing Date, utilizing the actual final Tax Bills for
                  the Properties for 1997 (or 1998 if available) adjusted for
                  any announced changes in rates of taxation. Prior to or at
                  Closing, Contributor shall pay or have paid all Tax Bills that
                  are due and payable prior to or on the Closing Date and shall
                  furnish evidence of such payment to Acquiror and the Title
                  Company. Each party's respective obligations to reprorate real
                  estate taxes shall survive the Closing and shall not merge
                  into any instrument of conveyance delivered at Closing. The
                  taxes to be prorated (i.e., county, school, city) for each
                  Property and the billing and accrual schedule for each such
                  tax are set forth in Exhibit K;

                           (e) All assessments, general or special, shall be
                  prorated as of the Closing 


<PAGE>


                  Date on a "due date" basis such that the Contributor shall
                  be responsible for any installments of assessments which are
                  first due or payable prior to the Closing Date and Acquiror
                  shall be responsible for any installments of assessments
                  which are first due or payable on or after the Closing Date;

                           (f) Commissions of leasing and rental agents for any
                  Lease entered into as of or prior to the Closing Date that are
                  due and payable at or prior to the Closing Date, whether with
                  respect to base lease term, future expansions, renewals, or
                  otherwise, shall be paid in full at or prior to Closing by the
                  Contributor, without contribution or proration from Acquiror;

                           (g) All Base Rents (as defined below) and other
                  charges actually received, including, without limitation, all
                  Additional Rent (as defined below), shall be prorated at
                  Closing. At the time(s) of final calculation and collection
                  from tenants of Additional Rent for 1998, there shall be a
                  re-proration between Acquiror and the Contributor as to
                  Additional Rent adjustments, which re-proration shall be paid
                  upon Acquiror's presentation of its final accounting to the
                  Contributor, certified as to accuracy by Acquiror. The party's
                  respective obligations to reprorate Additional Rent shall
                  survive the Closing and shall not merge into any instrument of
                  conveyance delivered at Closing. At the Closing, no
                  "Delinquent Rents" (rents or other charges which are due and
                  owing as of the Closing) shall be prorated in favor of the
                  Contributor. Notwithstanding the foregoing, Acquiror shall use
                  reasonable efforts after the Closing Date to collect any
                  Delinquent Rents due to the Contributor from tenants. Further,
                  after the Closing Date, the Contributor shall continue to have
                  the right, enforceable at its sole expense, to pursue legal
                  action against any tenant (and any guarantors) who have
                  defaulted, prior to the Closing Date, under a Lease; provided,
                  however, that the Contributor gives Acquiror advance written
                  notice of its intent to pursue such action and further
                  provided that the Contributor shall have no right to terminate
                  any Lease (or any right to dispossess any tenant thereunder).
                  All rents and other charges received from any tenant after the
                  Closing by and for the benefit of Acquiror shall be applied,
                  first, against current and past due rental obligations owed
                  to, or for the benefit of, Acquiror with respect to those
                  rental obligations accruing subsequent to the Closing Date
                  (including, but not limited to, obligations to replenish any
                  security deposit withdrawal by the Contributor or Acquiror),
                  or any obligations accruing prior to the Closing Date that the
                  Contributor does not pay or for which Acquiror does not
                  receive a credit at Closing, and second, any excess shall be
                  delivered to the Contributor, but only to the extent of
                  Delinquent Rents owed to, and for the benefit of, the
                  Contributor for the period prior to the Closing Date (in no
                  event, however, shall any sums be paid to the Contributor to
                  the extent it has been previously reimbursed for such default
                  out of any security deposit);

                           (h) The Contributor and Acquiror acknowledge that
                  various of the Properties may contain certain vacancies as of
                  the date of this Agreement and all such current vacancies are
                  reflected on the Rent Roll (the "Vacancies"). If a new lease
                  for any such Vacancy ("Vacancy Lease") is executed prior to
                  Closing and the terms of such Vacancy Lease have been approved
                  by Acquiror, then the applicable Contributor and Acquiror
                  shall each bear a pro rata share, of the tenant improvement
                  costs and brokerage commission attributable to the Vacancy
                  Lease (the "Vacancy Lease Costs"). The Contributor's
                  proportionate share of the Vacancy Lease Costs shall be based
                  on that portion of the Vacancy Lease's term that elapses prior
                  to Closing and Acquiror's proportionate share shall be based
                  on that portion of the Vacancy Lease's term that remains
                  unexpired as of the Closing Date. The Contributor shall pay
                  all Vacancy Lease Costs and Acquiror shall reimburse the
                  Contributor for its proportionate share of such Vacancy Lease
                  Costs by way 


<PAGE>


                  of an Adjustment in the Contribution Consideration. In the
                  event that this Agreement is terminated prior to Closing,
                  then Acquiror shall have no liability or obligation with
                  respect to any Vacancy Lease or any Vacancy Lease Costs.

                           (i) Such other items that are customarily prorated in
                  transactions of this nature shall be ratably prorated.

                       (ii) For purposes of calculating prorations, Acquiror
         shall be deemed to be in title to the Properties, and therefore
         entitled to the income therefrom and responsible for the expenses
         thereof, for the entire Closing Date. All such prorations shall be made
         on the basis of the actual number of days of the year and month that
         shall have elapsed as of the Closing Date. Except with respect to
         general real estate and personal property taxes that are to be
         reprorated as aforesaid, any proration which must be estimated at the
         Closing shall be reprorated and finally adjusted within ninety (90)
         days after the Closing Date; otherwise all prorations shall be final.
         The provisions of the foregoing sentence shall survive the Closing.

                  D. Closing Costs. All transfer taxes, documentary stamps,
intangible taxes and similar taxes or charges and cure expenses shall be paid by
Contributor. All title insurance premiums, search fees, survey costs and
recording charges shall be paid by Acquiror. Contributor and Acquiror shall each
pay for one-half (1/2) of the escrow fees charged by the Escrowee. Each party
shall pay its own attorney's fees and all of its other expenses, except as
otherwise expressly set forth herein.

                  E. Possession. Upon consummation of the Closing, Contributor
shall deliver to Acquiror full and complete possession of the Properties,
subject only to the Permitted Exceptions.

         7.       CASUALTY, LOSS AND CONDEMNATION

                  If, prior to the Closing, the Properties or any part thereof
shall be condemned, or destroyed or materially damaged by fire or other casualty
(that is, damage or destruction in excess of One Hundred Thousand and 00/100
Dollars $100,000.00), Contributor shall immediately so notify Acquiror and
Acquiror shall have the option either to terminate this Agreement upon written
notice to Contributor or to consummate the transaction contemplated by this
Agreement notwithstanding such condemnation, destruction or material damage. If
Acquiror elects to consummate the transaction contemplated by this Agreement,
Acquiror shall be entitled to receive the condemnation proceeds or settle the
loss under all policies of insurance applicable to the destruction or damage and
receive the proceeds of insurance applicable thereto, and Contributor shall, at
the Closing and thereafter as necessary, execute and deliver to Acquiror all
required proofs of loss, assignments of claims and other similar items. If
Acquiror elects to terminate this Agreement, the Earnest Money shall be returned
to Acquiror by Escrowee, in which event this Agreement shall, without further
action of the parties, become null and void and neither party shall have any
rights or obligations under this Agreement. If there is any other damage or
destruction (that is, damage or destruction of One Hundred Thousand and 00/100
Dollars $100,000.00 or less) to the Properties or any part thereof, Contributor
shall either repair such damage prior to the Closing or, at Acquiror's option,
assign all insurance claims pertaining to such damage or destruction to Acquiror
by executing and delivering to Acquiror at the Closing and thereafter as
necessary all required proofs of loss, assignments of claims and other similar
items. If Acquiror elects to take an assignment of all insurance claims as
aforesaid, Acquiror shall receive at the Closing a credit against the
Contribution Consideration in an amount equal to any deductible(s) applicable
thereto.

         8.       REPRESENTATIONS AND WARRANTIES

                  A. Each Contributor represents and warrants, jointly and
severally, to Acquiror that the following are true, complete and correct as of
the date of this Agreement:

                        (i) Contributor is a corporation duly organized, validly
         existing and in good standing under the laws of the State of New York
         and has all requisite corporate power and authority to own, lease and
         operate its properties and assets as they are now owned, leased and
         operated and to carry on its business as now conducted and presently
         proposed to be conducted. Contributor is duly qualified, licensed or
         admitted to do business and is in good standing in those jurisdictions
         in which the ownership, use, or leasing of its assets and properties,
         or the conduct or nature of its business makes such qualification,
         licensing or admission necessary, except for failures to be so
         qualified, licensed or admitted and in good standing that individually
         or in the aggregate would not materially adversely affect the
         Properties, assets, business, operations or condition (financial or
         otherwise) of Contributor or the ability of Contributor to perform its
         obligations under this Agreement (a "Contributor Material Adverse
         Effect").

                       (ii) Contributor has full corporate power and authority
         and each OP Unit Recipient has full legal right, capacity and power to
         enter into, execute and deliver this Agreement and to perform fully its
         obligations hereunder. The execution, delivery and performance by
         Contributor of this Agreement and the other documents to be delivered
         by Contributor at Closing, and the consummation by Contributor of the
         transactions contemplated hereby and thereby have been duly and validly
         authorized by all necessary corporate action on the part of Contributor
         and no other corporate proceedings on the part of Contributor,
         including of its shareholders, are necessary to authorize the
         execution, delivery and performance by Contributor of this Agreement
         and the other documents to be delivered by Contributor at Closing and
         the consummation by Contributor of the transactions contemplated hereby
         and thereby. This Agreement has been duly executed and delivered by
         Contributor and each OP Unit Recipient and is a valid and binding
         obligation of Contributor and each OP Unit Recipient, enforceable
         against Contributor and each OP Unit Recipient in accordance with its
         terms.

                      (iii) Neither the execution and delivery of this Agreement
         by Contributor nor the performance by Contributor or the OP Unit
         Recipients of the transactions contemplated hereby will: (a) violate or
         conflict with any of the provisions of the Certificate of Incorporation
         or By-Laws (or similar governing documents) of Contributor; (b) except
         as would not have a Contributor Material Adverse Effect, violate,
         result in a breach of, conflict with, result in the acceleration of, or
         entitle any party to accelerate the maturity or the cancellation of the
         performance of any obligation under, or result in the creation or
         imposition of any Lien (as defined below) in or upon any of the
         Properties or assets of Contributor or constitute a default (or an
         event which might, with the passage of time or the giving of notice, or
         both, constitute a default) under any mortgage, indenture, deed of
         trust, lease, contract (including any Service Contract), loan or credit
         agreement, license or other instrument to which Contributor is a party
         or by which it or any of its assets may be bound or affected; or (c)
         except as would not have a Contributor Material Adverse Effect, violate
         or conflict with any provision of any statute, law, rule, regulation,
         code or ordinance or any judgment, decree, order, writ, permit or
         license (collectively, "Laws or Orders") applicable to Contributor, the
         Properties or assets of Contributor. Other than those which have been
         obtained or made prior to the date hereof, or as set forth in Schedule
         8A(iii) attached to this Agreement, no consent or approval or action
         of, filing with or notice to any Governmental or Regulatory Authority
         (as defined below), any creditor, investor, partner, shareholder, or
         tenant-in-common of Contributor, or other party is necessary or
         required for the execution, delivery and performance by Contributor of
         this 


<PAGE>


         Agreement, or the consummation of the transactions contemplated
         hereby, other than such consents, approvals, actions, filings and
         notices which the failure to obtain or make, individually or in the
         aggregate, would not reasonably be expected to have a Contributor
         Material Adverse Effect.

                       (iv) To the best of Contributor's knowledge, it is not
         (a) in violation of its certificate of incorporation or by-laws, (b) in
         default, and no event has occurred which, with notice or lapse of time
         or both, would constitute such a default, in the due performance or
         observance of any obligation, agreement, covenant or condition
         contained in any indenture, mortgage, deed of trust, loan or credit
         agreement, lease, contract (including any Service Contract) or other
         material agreement or instrument to which it is a party or by which it
         is bound or to which any of its properties or assets is subject or by
         which it, or any of them, may be materially affected, or (c) in
         violation or in conflict with any provision of any Laws or Orders
         applicable to Contributor, the Properties or assets of Contributor,
         except in the case of clauses (b) and (c) for such defaults, violations
         or conflicts that individually or in the aggregate would not reasonably
         be expected to have a Contributor Material Adverse Effect. To the best
         of Contributor's knowledge, (x) it is not in default under any of the
         documents, recorded or unrecorded, referred to in the Title Commitments
         for the Properties, and (y) Contributor nor any of the Properties is in
         default under any certificates of occupancy, licenses, permits,
         authorizations and approvals required by law or by any Governmental or
         Regulatory Authority having jurisdiction thereof in respect of
         Contributor or its assets, the Properties, occupancy of the Properties
         or any present use thereof, except in the case of clauses (x) and (y),
         for such defaults that individually or in the aggregate would not
         reasonably be expected to have a Contributor Material Adverse Effect.

                        (v) Contributor is the sole owner of, and has good and
         marketable title to, the Properties free and clear of all liens,
         encumbrances, pledges, claims, security interests, demands, easements,
         covenants, conditions, restrictions and encroachments of any kind or
         nature (collectively, "Liens") other than Permitted Exceptions and
         liens that will be discharged or otherwise provided for at or prior to
         the Closing. The Contributor has not received any notice alleging that
         it is in default in compliance with the terms and provisions of any of
         the covenants, conditions, restrictions, rights-of-way or easements
         constituting one or more of the Permitted Exceptions. There are no
         development or other rights associated with any Property which are not
         being transferred to Acquiror under this Agreement or the documents
         contemplated by this Agreement.

                       (vi) To the best of Contributor's knowledge, the
         Improvements were constructed in a good, workmanlike and substantial
         manner, and in conformity with all rules, regulations, laws and
         ordinances applicable at the time of construction. Contributor has
         obtained and paid for all permits and certificates (including, without
         limitation, permits and certificates for water, plumbing, sewers and
         sewage treatment, electric, heating, ventilating, air conditioning,
         drainage and occupancy) required under any Federal, state or local law,
         ordinance, rule or regulation or by any governmental or
         quasi-governmental agency having jurisdiction over the Properties, and
         all of the same are in good standing. To the best of Contributor's
         knowledge, except as set forth in Schedule 8A(vi) attached to this
         Agreement, the Improvements and the tangible Personal Property are free
         from material defects; and the Properties and each part thereof have
         adequate drainage and contain not less than the minimum number of
         parking spaces required under applicable law. Except as set forth in
         Schedule 8A(vi) attached to this Agreement, each of the Properties
         abuts a public right-of-way, and the rights of ingress and egress with
         respect thereto as they currently exist are not restricted or limited
         in any manner.

                      (vii) All of Contributor's insurance policies are in full
         force and effect and Contributor is not in default with respect to any
         material provisions contained in any such policy. 


<PAGE>


         Neither Contributor, nor to the best of Contributor's knowledge, any
         agent of Contributor, has received from any insurer any notice with
         respect to any defects or inadequacies affecting all or any part of
         the Properties, any notice of cancellation or non-renewal of any such
         policy, or any notice that any insurance premiums will be materially
         increased in the future or that any insurance coverage under such
         policies will not be available in the future on substantially the same
         terms as now in effect.

                     (viii) Except as set forth in Schedule 8A(viii) attached to
         this Agreement, there is no judicial, municipal or administrative
         action, suit, arbitration, proceeding or investigation pending or, to
         the best of Contributor's knowledge, threatened against, relating to or
         affecting Contributor, its assets, the Properties or any part thereof
         before any court or governmental department, commission, board, agency
         or instrumentality, of the United States or any state, county, city or
         other political subdivision (a "Governmental or Regulatory Authority"),
         including, without limitation, proceedings for or involving collections
         (other than collections in the ordinary course of business),
         condemnation, eminent domain, alleged building code or environmental or
         zoning violations, or personal injuries or property damage alleged to
         have occurred at any of the Properties or by reason of the condition,
         use of, or operations on, such Property. No attachments, execution
         proceedings, assignments for the benefit of creditors, insolvency,
         bankruptcy or other similar proceedings are pending or, to the best of
         Contributor's knowledge, threatened against Contributor or any of the
         OP Unit Recipients.

                       (ix) Except as set forth in Schedule 8A(ix) attached to
         this Agreement, Contributor has not received from any Governmental
         Authority any written notice of zoning, building, fire, health code,
         environmental or other violations of applicable laws, rules, ordinances
         codes and regulations with respect to the Properties, or any part
         thereof.

                        (x) The Service Contracts comprise every contract,
         agreement, relationship and commitment, oral or written, other than the
         Leases and the Existing Mortgages that affect the Properties or to
         which Contributor is a party or by which it is bound, including,
         without limitation, all agreements relating to the management,
         construction, operation, maintenance or repair of any Property, the
         purchase of materials, supplies, equipment, machinery parts, products
         and services, and the lease of any property, real or personal. The
         Service Contracts are in full force and effect and have not been
         modified, amended or altered, in writing or otherwise. Except as set
         forth in Schedule 8A(x) attached to this Agreement, neither Contributor
         nor, to the best of Contributor's knowledge, any other party is in
         default under the terms of any Service Contract. Except as otherwise
         noted on Exhibit C, each Service Contact is cancelable by Contributor
         (or its assignees or successors) without payment of any penalty upon
         not more than thirty (30) days prior notice.

                       (xi) Contributor has no patents, trademarks, servicemarks
         or trade names used in connection with the Properties, except for the
         name "Galesi Group." To the best of Contributor's knowledge, the use of
         such names does not conflict with any rights of others with respect
         thereto. There is no claim pending or, to the best of Contributor's
         knowledge, threatened against Contributor with respect to alleged
         infringement of any patent, trademark, servicemark or trade name
         related to the Properties.

                      (xii) Without limiting any other warranty or
         representation of Contributor:

                           (a) there is no proceeding, plan, study or effort by
                  any governmenta authority or agency pending, or to the best of
                  Contributor's knowledge, threatened, which in any way affects
                  or would affect the present use, improvements on, size or
                  zoning of any of the Properties (and Contributor has received
                  no notice from any governmental authority of any 


<PAGE>


                  such plan, study or effort), and there is no existing, or to
                  the best of Contributor's knowledge, proposed or
                  contemplated plan to widen, modify or realign any street or
                  highway or any existing, or to the best of Contributor's
                  knowledge, proposed or contemplated eminent domain
                  proceedings that would affect any of the Properties in any
                  way whatsoever (and Contributor has received no notice from
                  any governmental authority of any such existing, proposed or
                  contemplated plan or proceedings);

                           (b) all laws, ordinances, codes, rules and
                  regulations of any Governmental and Regulatory Authority,
                  bearing on the construction, maintenance, repair or operation
                  of each of the Properties have been complied with by
                  Contributor at its sole cost, except the non-compliance with
                  which would not reasonably be expected to have a Material
                  Adverse Effect; and

                           (c) none of the Properties is located in any area
                  designated by any governmental authority or agency as being a
                  flood prone or flood risk area (whether pursuant to the Flood
                  Disaster Act of 1973, as amended, or otherwise) and the
                  requirements of the National Flood Insurance Program are not
                  applicable to the Properties or any part thereof.

                     (xiii) Except as set forth in Schedule 8A(xiii) attached to
         this Agreement, Contributor is not in default in respect of any of its
         obligations or liabilities pertaining to the Properties (including,
         without limitation, Contributor's obligations under any of the Leases),
         and there is no state of facts or circumstances or condition or event
         which, after notice or lapse of time, or both, would constitute or
         result in any such default.

                      (xiv)         With respect to the Leases:

                           (a) Except as set forth on the Rent Roll, each of the
                  Leases is in full force and effect, and has not been modified,
                  amended, or altered, in writing or otherwise. Contributor has
                  not received any notice of any material claim of any sort that
                  has been asserted by anyone adverse to the rights of
                  Contributor under any of the Leases, or affecting or
                  questioning the rights of Contributor of the continued
                  possession of the leased or subleased premises under any such
                  Lease. Except as set forth on the Rent Roll, each tenant is
                  legally required to pay all sums and perform all of its
                  obligations set forth in the Lease, without concessions,
                  abatements, offsets or other bases for relief or adjustment;

                           (b) Except as set forth on the Rent Roll, all
                  material obligations of the lessor under the Leases that
                  accrue to the date of Closing have been performed, including,
                  but not limited to, all required tenant improvements, cash or
                  other inducements, rent abatements or moratoria, installations
                  and construction (for which payment in full has been made or
                  will be made prior to Closing, or subject to proration
                  hereunder in all cases), and, to the best of Contributor's
                  knowledge, each tenant has unconditionally accepted lessor's
                  performance of such obligations. Except as set forth on the
                  Rent Roll, no tenant has asserted any offsets, defenses or
                  claims available against rent payable by it or other
                  performance or obligations otherwise due from it under any
                  Lease, which assertion remains outstanding;

                           (c) Except as set forth on the Rent Roll, no tenant
                  is currently in default under or is in arrears (for more than
                  30 days) in the payment of any sums or in the performance of
                  any monetary obligations required of it under its Lease, and
                  Contributor has no knowledge of any other default under any
                  such Lease;


<PAGE>


                           (d) Except as set forth in the Rent Roll, during the
                  12-month period immediately preceding the date hereof: (i) no
                  tenant has, at any time, been more than 30 days delinquent in
                  its respective payment of any and all sums due under the terms
                  of its respective Lease; (ii) no tenant has requested that
                  Contributor provide that tenant with any reduction in the
                  tenant's monetary obligations under its Lease; (iii) no tenant
                  has requested that Contributor, in its capacity as landlord,
                  permit the tenant to sublease its leased premises, or assign
                  its Lease, or terminate its Lease on an accelerated basis;
                  (iv) Contributor has not "written off" any delinquent sums
                  owed by any tenant to satisfy its obligation to contribute to
                  the payment of real estate taxes, common area maintenance
                  charges, and insurance premiums; and (v) Contributor has not
                  had (nor is it currently engaged in) any dispute (whether of a
                  formal or an informal nature) with any tenant concerning that
                  tenant's obligations to make payments under the terms of its
                  Lease toward real estate taxes, insurance premiums and common
                  area maintenance charges or other charges imposed under its
                  Lease;

                           (e) Except as set forth on the Rent Roll, Contributor
                  has not received any written notice from any tenant stating
                  that a petition in bankruptcy has been filed or is threatened
                  to be filed by or against it;

                           (f) Except with respect to security deposits, neither
                  base rent ("Base Rent"), nor regularly payable estimated
                  tenant contributions or operating expenses, insurance
                  premiums, real estate taxes, common area charges, and similar
                  or other "pass through" or non-base rent items including,
                  without limitation, cost-of-living or so-called "C.P.I." or
                  other such adjustments (collectively, "Additional Rent"), nor
                  any other material item payable by any tenant under any Lease
                  has been heretofore prepaid for more than one month;

                           (g) To the best of Contributor's knowledge, no
                  guarantor(s) of any Lease has been released or discharged,
                  partially or fully, voluntarily or involuntarily, or by
                  operation of law, from any obligation under or in connection
                  with any Lease or any transaction related thereto;

                           (h) Except as set forth in Schedule 8A(xiv)(h)
                  attached to this Agreement, there are no brokers' commissions,
                  finders' fees, or other charges payable or to become payable
                  to any third party on behalf of Contributor in connection with
                  any Lease, including, but not limited to, any exercised
                  option(s) to expand or renew;

                           (i) Each security deposit set forth on the Rent Roll
                  shall be assigned to Acquiror at the Closing (or Acquiror
                  shall receive a credit therefor). Except as set forth on the
                  Rent Roll, (i) no tenant or any other party has asserted any
                  claim (other than for customary refund at the expiration of a
                  Lease) to all or any part of any security deposit and (ii)
                  Contributor has not applied any portion of any security
                  deposit to the payment of any sums due from any tenant under a
                  Lease;

                           (j) Contributor shall pay (or Acquiror shall receive
                  a credit therefor), and retains sole and exclusive
                  responsibility for, all expenses due on or before the Closing
                  Date connected with or arising out of the negotiation,
                  execution and delivery of the Leases, including, without
                  limitation, brokers' commissions (including those applicable,
                  if any, to future expansions or renewals by a tenant), leasing
                  fees and recording fees (as well as the cost of all tenant
                  improvements not required to be paid for by tenants);


<PAGE>


                           (k) No tenant has, by virtue of its Lease or any
                  other agreement or understanding, any purchase option with
                  respect to any of the Properties, or any portion thereof, or
                  any right of first refusal to purchase any of the Properties,
                  or a portion thereof, whether triggered by the transactions
                  contemplated by this Agreement or by a subsequent sale of any
                  of the Properties or a portion thereof. Except as set forth in
                  Schedule 8A(xiv)(k) attached to this Agreement, no tenant has,
                  by virtue of its Lease or any other agreement or understanding
                  any of the following (i) the option to terminate its Lease
                  prior to the stated expiration date and (ii) the option to
                  reduce the rentable space at any of the Properties that such
                  tenant is currently occupying; and

                           (l) Except as set forth on the Rent Roll: (i) to the
                  best of Contributor's knowledge, no tenant has sublet its
                  leased premises; and (ii) there are no outstanding requests
                  from any tenant to Contributor, requesting any consent to an
                  assignment of the tenant's Lease or to a sublease of all or
                  some portion of a tenant's leased premises.

                       (xv) The Properties have been fully valued and assessed
         for property tax purposes. Except as set forth in Schedule 8A(xv)
         attached to this Agreement, there are no general or special assessments
         applicable to the Properties or any part thereof. The bill or bills
         issued for the years 1994, 1995, 1996 and 1997, for all real estate
         taxes and personal property taxes and copies of any and all notices
         pertaining to real estate taxes or assessments applicable to the
         Properties (the "Tax Bills") (and to Contributor's knowledge, the only
         real estate tax bills applicable to the Properties) have been delivered
         to Acquiror. Except as set forth in Schedule 8A(xv) attached to this
         Agreement, Contributor has not received any notice of any proposed or
         actual increase in the assessed valuation of or rate of taxation of any
         or all of the Properties from that reflected in the most recent Tax
         Bills. Except as set forth in Schedule 8A(xv) attached to this
         Agreement, there is not now pending, and Contributor agrees that it
         will not, without the prior written consent of Acquiror (which consent
         shall not be unreasonably withheld or delayed), institute prior to the
         Closing Date, any proceeding or application for a reduction in the real
         estate tax assessment of any of the Properties or any other relief for
         any tax year. Other than the amounts disclosed by the Tax Bills, no
         other real estate taxes have been, or to Contributor's knowledge, will
         be, assessed against the Properties, or any portion thereof, in respect
         of the year 1997 or any prior year, and no special assessments of any
         kind (special, bond or otherwise) are or have been levied against the
         Properties, or any portion thereof, that are outstanding or unpaid,
         and, to Contributor's knowledge, none will be levied prior to Closing.
         Contributor has not entered into any agreements with attorneys or,
         consultants or other parties with respect to real estate taxes
         applicable to any of the Properties that will be binding on Acquiror
         after the Closing.

                      (xvi) Contributor has prepared and timely filed all tax
         returns required to be filed on or before the date hereof with respect
         to the Properties, which tax returns are true, correct and complete in
         all material respects. Contributor has paid or made provision for the
         payment of all taxes with respect to the Properties that are due or
         claimed to be due from it on or before the date hereof by any
         governmental taxing authority. No federal, state, local or foreign
         taxing authority has asserted any tax deficiency, lien, interest or
         penalty or other assessment against the Properties or Contributor which
         has not been paid and there is no pending audit or inquiry from any
         federal, state, local or foreign tax authority relating to the
         Properties or Contributor that may be expected to result in a tax
         deficiency, lien interest or other assessment against the Properties.

                     (xvii) The Personal Property is all of the personal
         property owned by Contributor and used in the operation of the
         Properties. Except as set forth in Schedule 8A(xvii) attached to this
         Agreement, Contributor has good title to the Personal Property, free
         and clear of any Liens. All such Personal Property is in good working
         condition, free of material defects, normal wear and tear

         excepted.

                    (xviii) This Agreement and all other documents and
         agreements executed by Contributor in connection with the transaction
         that is the subject of this Agreement (collectively, the "Contributor's
         Documents") are binding on Contributor and enforceable against
         Contributor in accordance with their respective terms, subject to
         bankruptcy and similar laws affecting the remedies or recourse of
         creditors generally and general principles of equity.

                      (xix) All financial information regarding the Properties
         furnished by Contributor to Acquiror is true, complete and correct; has
         been compiled in accordance with generally accepted accounting
         principles and accurately set forth in all material respects the
         results of the operations of the Properties for the periods covered.

                       (xx) All management contracts pertaining to the
         Properties will be terminated as of the Closing.

                      (xxi) Except as set forth in Schedule 8A(xxi) attached to
         this Agreement, all utilities (including, without limitation, gas,
         electricity, telephone, water and sanitary and storm sewers) have been
         completed to the lot lines of the Land, are connected to the
         Improvements as necessary, and all connection, hook-up, tap fees and
         the like have been paid.

                     (xxii) The Existing Mortgages constitute all of the
         mortgages or deeds of trust presently encumbering the Properties or any
         portion thereof. Contributor has complied with (and, prior to Closing,
         shall continue to comply with) in all material respects the terms of,
         and all notices or correspondence received from the holder of, the
         promissory notes evidencing the loans secured by the Existing Mortgages
         (the "Existing Notes"). Contributor has paid (and, at all times prior
         to Closing, shall pay), when and as due, all sums due under the
         Existing Mortgages, the Existing Notes and all other loan documents
         securing the Existing Notes (the "Other Loan Documents"). The Existing
         Notes, the Existing Mortgages and the Other Loan Documents are in full
         force and effect, and Contributor has not received any notice of a
         default thereunder that remains outstanding. Upon Contributor's
         request, Contributor will deliver to Acquiror true, complete and
         accurate copies of the Existing Notes, the Existing Mortgages and the
         Other Loan Documents. At Closing, the Existing Indebtedness as
         contemplated by Section 11A(vii) will be the only indebtedness
         encumbering the Properties and will be prepayable, in full, on the
         Closing Date without imposition of any penalty or premium.

                    (xxiii) No representation or warranty made by Contributor in
         this Agreement, no exhibit attached hereto with respect to the
         Properties, and no schedule contained in this Agreement contains any
         untrue statement of a material fact, or omits to state a material fact
         necessary in order to make the statements contained therein not
         misleading. All items delivered by or on behalf of Contributor pursuant
         to this Agreement are true, accurate, correct and complete in all
         material respects, and fairly present the information set forth in a
         manner that is not misleading. The copies of all documents and other
         agreements delivered or furnished and made available by or on behalf of
         Contributor to Acquiror pursuant to this Agreement constitute all of
         and the only Leases and other agreements to which Contributor is
         presently a party relating to or affecting the ownership, leasing,
         management and operation of the Properties, there being no "side" or
         other agreements, written or oral, in force or effect, to which
         Contributor is a party or to which any Property is subject.

                     (xxiv) The OP Units are being acquired by each of the OP
         Unit Recipients with the present intention of holding the OP Units for
         purposes of investment and not with a view towards sale or any other
         distribution. Each of the OP Unit Recipients recognizes that he may be
         


<PAGE>


         required to bear the economic risk of an investment in the OP Units for
         an indefinite period of time. Each OP Unit Recipient is an Accredited
         Investor. Each OP Unit Recipient has such knowledge and experience in
         financial and business matters so as to be fully capable of evaluating
         the merits and risks of an investment in the OP Units. Each OP Unit
         Recipient has received and reviewed the following documents: (A) the
         Form 10-K for the year ended December 31, 1996 for the REIT and
         Acquiror; (B) the annual proxy statement of the REIT for the 1997
         annual meeting and the proxy statement of the REIT for the special
         meeting of stockholders which was held on December 12, 1997; (C) the
         Form 10-Q for the REIT and Acquiror for the quarters ended March 31,
         1997, June 30, 1997, and September 30, 1997, respectively; (D) the Form
         8-Ks filed by the REIT and Acquiror since December 31, 1996 and (E) the
         Partnership Agreement. Each OP Unit Recipient has been afforded the
         opportunity to ask questions of those persons he considers appropriate
         and to obtain any additional information he desires in respect of the
         OP Units and the business, operations, conditions (financial and
         otherwise) and current prospects of Acquiror and the REIT. Each OP Unit
         Recipient has consulted his own financial, legal and tax advisors with
         respect to the economic, legal and tax consequences of delivery of the
         OP Units and has not relied on Acquiror, the REIT or any of their
         officers, directors, affiliates or professional advisors for such
         advice as to such consequences.

                      (xxv) Except as set forth in Schedule 8A(xxv) attached to
this Agreement:

                           (a) The Properties are owned and operated by
                  Contributor in compliance with all Environmental Laws, except
                  for instances of non-compliance as would not individually or
                  in the aggregate reasonably expected to have a Contributor
                  Material Adverse Effect.

                           (b) There have been no past and there are no pending
                  or, to the knowledge of Contributor, threatened (in writing)
                  claims, complaints, notices, correspondence or requests for
                  information received by Contributor with respect to any
                  violation or alleged violation of any Environmental Law or
                  Environmental Permit or with respect to any corrective or
                  remedial action for or cleanup of the Properties or any
                  portion thereof.

                           (c) There have been no Releases of a Hazardous
                  Material at, on, under, in or about any of the Properties or
                  any portion thereof during any period that Contributor owned
                  or leased such Property, or to the best of Contributor's
                  knowledge, prior thereto. None of the Properties is listed, or
                  to the best of Contributor's knowledge, proposed for listing,
                  on the National Priorities List promulgated pursuant to CERCLA
                  (the "NPL") or on any similar state or other list of sites
                  that require or may require corrective or remedial action.

                           (d) To the best of Contributor's knowledge, no
                  conditions exist at, on, under, in or about the Properties or
                  any portion thereof that, with the passage of time or the
                  giving of notice or both, would give rise to any claim,
                  liability or obligation under any Environmental Law or
                  Environmental Permit.

                           (e) Contributor has been issued all Environmental
                  Permits required for the operation of the Properties. All such
                  Environmental Permits are in full force and effect and
                  Contributor is in compliance in all material respects with the
                  terms and conditions of such Environmental Permits.

                           (f) The Properties are not listed, or to the
                  knowledge of Contributor, proposed or nominated for listing on
                  the NPL or on any other similar state or other list of sites
                  that require or may require corrective or remedial action.

                           (g) Contributor has not transported, disposed of or
                  treated, or arranged for the transportation, disposal or
                  treatment of, any Hazardous Material from the Properties or
                  any portion thereof to any location that is: (i) listed, or to
                  the best of Contributor's knowledge, proposed or nominated for
                  listing, on the NPL or on any other similar list or (ii) the
                  subject of any pending, or to the best of Contributor's
                  knowledge, threatened, Federal, state or local enforcement
                  action or other investigation under any Environmental Law.

                           (h) There are no underground storage tanks at, on or
                  under the Properties or any portion thereof. Contributor has
                  not removed, closed or abandoned any underground storage tanks
                  at any of the Properties, and Contributor has no knowledge of
                  the existence, abandonment, closure or removal of underground
                  storage tanks at any of the Properties.

                           (i) There have been no environmental investigations,
                  studies, audits, tests, reviews or other analyses conducted
                  by, or which are in the possession of, Contributor in relation
                  to any Property which have not been delivered to Acquiror
                  prior to the execution of this Agreement.

                  B. Contributor represents and warrants to Acquiror that, as of
the Closing, each of the representations and warranties set forth in Section 8A
above shall be true, complete and correct except for changes in the operation of
the Properties occurring prior to the Closing that are specifically permitted by
or pursuant to this Agreement.

                  C. Acquiror represents and warrants to Contributor that the
following are true, complete and correct as of the date of this Agreement:

                        (i) Acquiror is a limited partnership duly formed,
         validly existing and in good standing under the laws of the State of
         Delaware and has all requisite partnership power and authority to own,
         lease and operate its properties and assets as they are now owned,
         leased and operated and to carry on its business as now conducted and
         presently proposed to be conducted. Acquiror is duly qualified,
         licensed or admitted to do business and is in good standing in those
         jurisdictions in which the ownership, use, or leasing of its assets and
         properties, or the conduct or nature of its business makes such
         qualification, licensing or admission necessary, except for failures to
         be so qualified, licensed or admitted and in good standing that
         individually or in the aggregate would not materially adversely affect
         the assets, business, operations or condition (financial or otherwise)
         of Acquiror or the ability of Acquiror to perform its obligations under
         this Agreement (an "Acquiror Material Adverse Effect").

                       (ii) Acquiror has all partnership power and authority to
         enter into, execute and deliver this Agreement and to perform fully its
         obligations hereunder. The execution, delivery and performance by
         Contributor of this Agreement and the other documents to be delivered
         by Acquiror at Closing, and the consummation by Acquiror of the
         transactions contemplated hereby and thereby are permitted under the
         Partnership Agreement, and at Closing will have been duly and validly
         authorized by all necessary partnership action on the part of Acquiror.
         This Agreement has been duly executed and delivered by Acquiror and is
         a valid and binding obligation of Acquiror, enforceable against
         Acquiror in accordance with its terms.

                      (iii) To the best of Acquiror's knowledge, it is not (a)
         in violation of the Partnership Agreement, (b) in default, and no event
         has occurred which, with notice or lapse of time or both, would
         constitute such a default, in the due performance or observance of any
         obligation, agreement, covenant or condition contained in any material
         indenture, mortgage, deed of trust, loan or credit agreement, lease,
         contract or other material agreement or instrument to which it is a
         party or by which it is bound or to which any of its properties or
         assets is subject or by which it, or any of them, may be materially
         affected, or (c) in violation or in conflict with any provision of any
         Laws or Orders applicable to Acquiror or its assets, except in the case
         of clauses (b) and (c) for such defaults, violations or conflicts that
         individually or in the aggregate would not reasonably be expected to
         have an Acquiror Material Adverse Effect.

                       (iv) The Partnership Agreement is in full force and
         effect and has not been 


<PAGE>


         further amended or modified.

                        (v) The OP Units to be issued to the OP Unit Recipients,
         when issued, sold and paid for pursuant to this Agreement and the
         Partnership Agreement, will be duly authorized, validly issued, and
         fully-paid.

                       (vi) There is no existing or, to Acquiror's knowledge,
         threatened, legal action or governmental proceedings of any kind
         involving Acquiror, any of its assets or the operation of any of the
         foregoing, which, if determined adversely to Acquiror or its assets,
         would have an Acquiror Material Adverse Effect.

                      (vii) The REIT is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Maryland
         and has all requisite corporate power and authority to own, lease and
         operate its properties and assets as they are now owned, leased and
         operated and to carry on its business as now conducted and presently
         proposed to be conducted. The REIT is duly qualified, licensed or
         admitted to do business and is in good standing in those jurisdictions
         in which the ownership, use, or leasing of its assets and properties,
         or the conduct or nature of its business makes such qualification,
         licensing or admission necessary, except for failures to be so
         qualified, licensed or admitted and in good standing that individually
         or in the aggregate would not materially adversely affect the assets,
         business, operations or condition (financial or otherwise) of the REIT
         (a "REIT Material Adverse Effect"). The REIT is the sole general
         partner of the Acquiror.

                     (viii) The REIT has all requisite corporate power and
         authority to enter into, execute and deliver this Agreement in its
         capacity as general partner of Acquiror and to perform fully its
         obligations hereunder in its capacity as general partner of Acquiror.
         The execution, delivery and performance by the REIT of this Agreement
         and the other documents to be delivered by the REIT at Closing, and the
         consummation by the REIT of the transactions contemplated hereby and
         thereby at Closing will have been duly and validly authorized by all
         necessary corporate action on the part of the REIT. This Agreement has
         been duly executed and delivered by the REIT and is a valid and binding
         obligation of the REIT, enforceable against the REIT in accordance with
         its terms.

                       (ix) To the best of the REIT's knowledge, it is not (a)
         in violation of its Certificate of Incorporation or by-laws, (b) in
         default, and no event has occurred which, with notice or lapse of time
         or both, would constitute such a default, in the due performance or
         observance of any obligation, agreement, covenant or condition
         contained in any material indenture, mortgage, deed of trust, loan or
         credit agreement, lease, contract or other material agreement or
         instrument to which it is a party or by which it is bound or to which
         any of its properties or assets is subject or by which it, or any of
         them, may be materially affected, or (c) in violation or in conflict
         with any provision of any Laws or Orders applicable to the REIT or its
         assets, except in the case of clauses (b) and (c) for such defaults,
         violations or conflicts that individually or in the aggregate would not
         reasonably be expected to have a REIT Material Adverse Effect.

                        (x) The Conversion Shares will be duly authorized and
         reserved for issuance and, to the extent delivered upon exchange of the
         OP Units, when issued, sold and paid for pursuant to this Agreement and
         the Partnership Agreement, will be validly issued, fully-paid and
         nonassessable.

                       (xi) The REIT is organized and operates as a "real estate
         investment trust" under Sections 856 through 860 of the Code. The REIT
         has elected to be taxed as a "real estate 


<PAGE>


         investment trust" under the Code.

                      (xii) There is no existing, or, to the REIT's knowledge,
         threatened legal action or governmental proceedings of any kind
         involving the REIT, any of its assets or the operation of any of the
         foregoing, which, if determined adversely to the REIT or its assets,
         would have a material adverse effect on the financial condition,
         business or operations of the REIT or its assets and which would
         interfere with the REIT's ability to perform its obligations under the
         REIT Documents.

                  D. Acquiror represents and warrants to Contributor that, as of
the Closing, each of the representations and warranties set forth in Section 8C
above shall be true, complete and correct.

                  E. Except as hereinafter provided, all representations and
warranties made in this Section 8 by Contributor and/or the OP Unit Recipient
(collectively, the "Contributor Party") and by Acquiror shall survive the
Closing until the second (2nd) anniversary of the Closing Date and shall not
merge into any instrument of conveyance delivered at the Closing; provided,
however, that the foregoing limitation shall not apply to the extent any claim
for indemnification is made under this Agreement with respect to any
representation, warranty, covenant or agreement that would otherwise terminate
pursuant to this Section 8E and a notice for indemnification shall have been
timely given under Section 14 on or prior to such termination date, in which
case such survival period will be extended as it relates to such related claims
until the related claim for indemnification has been satisfied or otherwise
resolved as provided in Section 14. This Section shall not limit in any way the
survival and enforceability of any covenant or agreement of the parties hereto
which by its terms contemplates performance after the Closing Date, which shall
survive for the respective periods set forth herein. Notwithstanding the
foregoing, the representations and warranties contained in Section 8A(xv), (xvi)
and (xxv) shall survive until the expiration of the statute of limitations
applicable thereto.

                  F. Contributor shall provide to Acquiror and its auditors (i)
during the Inspection Period and following the Closing, access at all reasonable
times to all financial and other information relating to the Properties
necessary for Acquiror and its auditors to prepare audited, and if necessary,
pro forma, financial statements in conformity with Regulations S-X of the
Securities and Exchange Commission ("SEC") or other materials required for any
registration statement, report or other disclosure to be filed with the SEC or
necessary to comply with any SEC rule or regulation, and (ii) at the Closing (or
prior thereto if required by Acquiror's auditors) an executed representations
letter, in form and substance reasonably satisfactory to Acquiror, as required
by Generally Accepted Auditing Standards as promulgated by the Auditing
Standards Division of the American Institute of Public Accountants, which
representation is required to enable an independent public accountant to render
an opinion on such financial statements; provided, however, that Acquiror shall
pay for any actual reasonable costs incurred by Contributor in connection with
its obligations under this Section 8F. The obligation of Contributor to provide
such access and representation letter shall survive the Closing and Contributor
shall indemnify and hold Acquiror harmless from and against any losses, costs,
expenses (including, without limitation, reasonable attorneys' fees and
expenses) and liabilities arising from Contributor's failure to comply with
these obligations. This indemnity shall survive the Closing for a period of two
(2) years.

         9.       ACQUIROR'S INSPECTION OF THE PROPERTIES

                  Subject to the provisions of Section 15B, during the period
extending to and including the 45th day from the date of this Agreement (the
"Inspection Period"), Acquiror and Acquiror's agents, engineers, surveyors,
consultants, appraisers, auditors and other representatives (collectively,
"Representatives") will, upon reasonable advance notice, be given the right to
enter upon the Properties and perform nondestructive physical tests and to
conduct any and all necessary engineering, environmental and other surveys,
tests and inspections at the Properties and to examine and evaluate any books
and records, agreements and documents within the possession of Contributor or
subject to its control (whether or not located at the Properties), as Acquiror
or Acquiror's agents may reasonably request. Contributor shall cooperate fully
with the inspections hereunder by Acquiror and its Representatives, and shall
furnish to Acquiror and its Representatives all such books, records, information
(financial or otherwise), data and agreements that Acquiror or Acquiror's
Representatives may reasonably request in connection with the investigations
hereunder, including but not limited to, copies of all leases, Services
Contracts, insurance policies, environmental reports, working drawings, plan and
specifications, surveys, appraisals, engineering and architect reports, real
estate tax bills and receipts, operating statements and related documents.
Acquiror shall have the right to perform a Phase One environmental assessment of
each of the Properties. Upon Acquiror's receipt of any such Phase One
assessment, it shall provide a copy thereof to Contributor (at no cost to
Contributor). If such Phase One assessment should recommend further inspections
and testing at the Properties, Acquiror shall have the option, to be exercised
by written notice given to Contributor prior to the expiration of the Inspection
Period, to extend the Inspection Period for one (1) additional period of thirty
(30) days. Except as otherwise provided herein, Acquiror's obligations under
this Agreement shall be contingent, only during the Inspection Period, upon
Acquiror being satisfied in its sole discretion with the results of its
investigation and evaluation of the Properties (the "Inspection Condition"). In
the event the Inspection Condition is not so satisfied, Acquiror shall notify
Contributor in writing (the "Termination Notice") prior to the expiration of the
Inspection Period that it is terminating this Agreement. If Acquiror shall give
the Termination Notice to Contributor prior to the expiration of the Inspection
Period, the Earnest Money shall be promptly returned to Acquiror and all parties
hereto shall be released from all further obligations and liabilities hereunder,
except with respect to the indemnity set forth in Section 15B. In the event that
Acquiror does not give the Termination Notice to Contributor prior to the
expiration of the Inspection Period, Acquiror shall be deemed to have waived the
Inspection Condition and Acquiror's right to terminate this Agreement pursuant
to this Section 9 shall be deemed deleted from this Agreement.

         10.      SCHEDULES

                  Within three (3) business days after the date of this
Agreement, to the extent not previously delivered, Contributor shall furnish to
Acquiror:

                        (i) a true, correct and complete copy of each written
         Service Contract and a true, correct and complete summary of each oral
         Service Contract;

                        (ii) true, correct and complete copies of all of the
         Leases;

                      (iii) copies of all operating statements for the
         Properties that are in the possession or control of Contributor for any
         time during the period commencing with the first day of the second full
         calendar year preceding the date of this Agreement and ending on the
         date of this Agreement; and

                       (iv) copies of the most recent survey of and title policy
         or commitment for each of the Properties in the possession or control
         of Contributor.


<PAGE>


         11.      CONDITIONS PRECEDENT

                  A. Acquiror's obligation to acquire the Properties shall be
subject to and contingent upon the following conditions precedent, any or all of
which Acquiror may waive only by a notice delivered in accordance with Section
15H:

                        (i) The issuance to Acquiror at the Closing of the Title
         Policies in accordance with Section 5B(i).

                       (ii) Contributor shall have obtained and delivered to
         Acquiror original executed tenant estoppel certificates (the "Tenant
         Estoppel Certificates") in substantially the form of Exhibit L attached
         hereto, dated not more than thirty (30) days before Closing, and
         executed by tenants under Leases leasing not less than ninety-five
         percent (95%) of the total aggregate gross rental income for all of the
         Properties, including, without limitation, those particular tenants
         listed in Exhibit M attached hereto ("Required Estoppel Tenants").
         Contributor shall use its reasonable, good faith and diligent efforts
         to obtain the Tenant Estoppel Certificates. To the extent that the
         Tenant Estoppel Certificate obtained from a tenant contains less than
         all of the Exhibit L information, or to the extent that, after
         satisfying the above condition, Contributor is unable to obtain Tenant
         Estoppel Certificates from all of the remaining tenants, then, at
         Closing, Contributor shall execute a Tenant Estoppel Certificate with
         respect to those Leases for which no or an insufficient Tenant Estoppel
         Certificate has been obtained (provided that in the case of an
         insufficient Tenant Estoppel Certificate the certification from
         Contributor shall be limited to the insufficient matters). With respect
         to tenants who have signed Leases but not yet taken occupancy, the
         Tenant Estoppel Certificate shall appropriately identify the full and
         complete Lease but will omit certifications that are inappropriate.

                      (iii) The representations and warranties made by
         Contributor in this Agreement shall be true and correct in all material
         respects on the Closing Date as if made on the Closing Date.

                       (iv) The delivery by Contributor of all documents
         (executed by parties other than Acquiror, where required) required
         under Section 6B(i) (except for the recordation required under Section
         6B(i)(n)).

                        (v) The delivery of all necessary consents and approvals
         of lenders under Existing Indebtedness to be assumed by Acquiror, and
         the consents and approvals set forth on Schedule 11A(vi) to this
         Agreement.

                       (vi) Contributor not being otherwise in default of its
         obligations under this Agreement.

                      (vii) The Existing Indebtedness shall total no more than
         $8,500,000 of principal, with no accrued and unpaid interest or
         prepayment fees or related charges.

                     (viii) All conditions precedent set forth in Section 11A of
         the Columbia Contribution Agreement shall have been satisfied or, if
         permissible, waived.

                  If the condition precedent set forth in Section 11A(i) is not
satisfied or waived on or prior to the Closing Date, Acquiror shall have the
rights and remedies set forth in Section 5C. If any of the conditions precedent
set forth in Section 11A(ii) or Section 11A(viii) (to the extent a condition
under the Columbia Contribution Agreement is not satisfied or, if permissible,
waived which allows for a similar termination right without the right to receive
costs and expenses) is not satisfied or waived on or prior to the 


<PAGE>


Closing Date, Acquiror shall have the right to terminate this Agreement upon
written notice to Contributor, and in which event Escrowee shall immediately
return the Earnest Money to Acquiror and this Agreement, without further action
of the parties, shall become null and void and neither party shall have any
further rights or obligations under this Agreement except with respect to the
Surviving Indemnities. If any of the conditions precedent set forth in Sections
11A(iii), (iv), (v), (vi) or (vii) or Section (viii) (to the extent a condition
under the Columbia Contribution Agreement is not satisfied or, if permissible,
waived which allows for a similar termination right with the right to receive
costs and expenses) is not satisfied or waived on or prior to the Closing Date,
then Acquiror shall have the rights and remedies provided in Section 13B.

                  B. Contributor's obligation to contribute and convey the
Properties shall be subject to and contingent upon the following conditions
precedent, any or all of which Contributor may waive by a notice delivered in
accordance with Section 15H:

                        (i) The representations and warranties made by Acquiror
         in this Agreement shall be true and correct in all material respects on
         the Closing Date as if made on the Closing Date.

                       (ii) The delivery by Acquiror of all documents (executed
         by Acquiror, where required) required under Section 6B(ii).

                      (iii) Acquiror not being otherwise in default of its
         obligations under this Agreement.

                       (iv) All conditions precedent set forth in Section 11B of
         the Columbia Contribution Agreement shall have been satisfied or, if
         permissible, waived.

                  If any of the conditions precedent set forth in Section 11B is
not satisfied or waived on or prior to the Closing Date, then Contributor shall
have the rights and remedies provided in Section 13A.

         12.      BROKERAGE

                  Contributor and Acquiror represent and warrant to each other
that neither they nor their affiliates have dealt with any broker, finder or the
like in connection with the transaction contemplated by this Agreement. Acquiror
and Contributor each agrees to indemnify, defend and hold the other harmless
from and against all loss, expense (including reasonable attorneys' fees and
court costs), damage and liability resulting from the claims of any other broker
or finder (or anyone claiming to be a broker or finder) on account of any
services claimed to have been rendered to the indemnifying party in connection
with the transaction contemplated by this Agreement. The provisions of this
Section shall survive the Closing or the sooner termination of this Agreement.


<PAGE>


         13.      DEFAULT AND REMEDIES

                  A. If the Closing does not occur due to Acquiror's default
hereunder, or the breach of the representations, warranties, covenants or other
terms of this Agreement, and such default or breach is not cured or remedied
within ten (10) business days after receipt of written notice thereof given by
Contributor to Acquiror, or otherwise waived by Contributor, Contributor may
terminate this Agreement and, as its sole remedy, receive the Earnest Money from
the Escrowee, as liquidated damages, in which event this Agreement shall be
deemed null and void and the parties shall be released from all further
obligations and liabilities under this Agreement, except with respect to the
indemnity set forth in Section 15B. It is recognized by Contributor and Acquiror
that the damages Contributor will sustain by reason of Acquiror's default,
breach or failure will be substantial, but difficult, if not impossible, to
ascertain. The Earnest Money has been determined by the parties as a reasonable
sum for damages and is intended not as a penalty, but as full liquidated
damages.

                  B. If, prior to the Closing, Contributor is in default with
respect to, or breaches, or fails to perform one or more of the representations,
covenants, warranties or other terms of this Agreement, and such default, breach
or failure is not cured or remedied within ten (10) business days after receipt
of written notice thereof given by Acquiror to Contributor, or otherwise waived
by Acquiror, or if the consent of Fleet National Bank to the consummation of the
transactions contemplated hereby is not obtained within 30 days from the date of
this Agreement, Acquiror as its sole remedy may either (a) terminate this
Agreement, in which event the Earnest Money shall be returned by the Escrowee to
Acquiror and Contributor shall reimburse Acquiror for its reasonable
out-of-pocket expenses incurred by Acquiror (not to exceed $50,000 in the
aggregate) pursuant to this Agreement and, upon such return and reimbursement,
the parties shall be released from all further obligations and liabilities under
this Agreement, except with respect to the Surviving Indemnities, or (b) sue for
specific performance (except in such case where such default, breach or failure
to perform is the result of the good faith failure despite best efforts by
Contributor to obtain the consent of Fleet National Bank or the subdivision
approval described in Section 6B(i)(n)). In the event Acquiror elects the remedy
set forth in (a) above, Contributor shall reimburse Acquiror for such expenses
within fifteen (15) days after Contributor's receipt of written notice from
Acquiror accompanied by copies of invoices detailing such expenses or such other
documentation that reasonably substantiates such expenses.

         14.      INDEMNIFICATION

                  A. Indemnification by Contributor. Contributor agrees to
indemnify Acquiror and its respective shareholders, directors, employees,
agents, partners and affiliates in respect of, and hold each of them harmless
from and against, any and all losses, liabilities (including punitive or
exemplary damages, fines or penalties and interest thereon), expenses (including
fees and disbursements of counsel and expenses of investigation and defense),
claims or other obligations of any value whatsoever (collectively, "Losses")
suffered, incurred or sustained by any of them or to which any of them becomes
subject, resulting from, arising out of or relating to (i) any breach of or
inaccuracy in any representation or warranty, or nonfulfillment of or failure to
perform or breach of any covenant or agreement on the part of Contributor
contained in this Agreement, or (ii) any default or dispute set forth in
Schedule 8A(xiii) attached to this Agreement.

                  B. Indemnification by Acquiror. Acquiror agrees to indemnify
the Contributor and its shareholders, officers, directors, employees, agents and
affiliates in respect of, and hold each of them harmless from and against, any
and all Losses suffered, incurred or sustained by any of them or to which any of
them becomes subject, resulting from, arising out of or relating to any breach
of or inaccuracy in any representation or warranty, or nonfulfillment of or
failure to perform or breach of any covenant or 


<PAGE>


agreement on the part of Acquiror contained in this Agreement.

                  C. Method of Asserting Claims. All claims for indemnification
by any Indemnified Party under this Section 14 will be asserted and resolved as
follows:

                        (i) In the event any claim or demand in respect of which
an Indemnified Party might seek indemnity under this Section 14 is asserted
against or sought to be collected from such Indemnified Party by a person or
entity other than Contributor, Acquiror or any Affiliate of the Contributor or
Acquiror (a "Third Party Claim"), the Indemnified Party shall deliver a Claim
Notice (as defined below) with reasonable promptness to the Indemnifying Party.
If the Indemnified Party fails to provide the Claim Notice with reasonable
promptness after the Indemnified Party receives notice of such Third Party
Claim, the Indemnifying Party will not be obligated to indemnify the Indemnified
Party with respect to such Third Party Claim to the extent that the Indemnifying
Party's ability to defend has been irreparably prejudiced by such failure of the
Indemnified Party. The Indemnifying Party will notify the Indemnified Party as
soon as practicable within the Dispute Period (as defined below) whether the
Indemnifying Party disputes its liability to the Indemnified Party under this
Section 14 and whether the Indemnifying Party desires, at its sole cost and
expense, to defend the Indemnified Party against such Third Party Claim.

                        (a) If the Indemnifying Party notifies the Indemnified
         Party within the Dispute Period that the Indemnifying Party desires to
         defend the Indemnified Party with respect to the Third Party Claim
         pursuant to this Section 14C(i), then the Indemnifying Party will have
         the right to defend, with counsel reasonably satisfactory to the
         Indemnified Party, at the sole cost and expense of the Indemnifying
         Party, such Third Party Claim by all appropriate proceedings, which
         proceedings will be vigorously and diligently prosecuted by the
         Indemnifying Party to a final conclusion or will be settled at the
         discretion of the Indemnifying Party (but only with the consent of the
         Indemnified Party in the case of any settlement that provides for any
         relief other than the payment of monetary damages or that provides for
         the payment of monetary damages as to which the Indemnified Party will
         not be indemnified in full pursuant to this Section 14). The
         Indemnifying Party will have full control of such defense and
         proceedings, including any compromise or settlement thereof; provided,
         however, that the Indemnified Party, at the sole cost and expense of
         the Indemnified Party, at any time prior to the Indemnifying Party's
         delivery of the notice referred to in the first sentence of this clause
         (a), may file any motion, answer or other pleadings or take any other
         action that the Indemnified Party reasonably believes to be necessary
         or appropriate to protect its interests; and provided further, that if
         requested by the Indemnifying Party, the Indemnified Party, at the sole
         cost and expense of the Indemnifying Party, will provide reasonable
         cooperation to the Indemnifying Party in contesting any Third Party
         Claim that the Indemnifying Party elects to contest. The Indemnified
         Party may participate in, but not control, any defense or settlement of
         any Third Party Claim controlled by the Indemnifying Party pursuant to
         this clause (a), and except as provided in the preceding sentence, the
         Indemnified Party will bear its own costs and expenses with respect to
         such participation. Notwithstanding the foregoing, the Indemnified
         Party may take over the control of the defense or settlement of a Third
         Party Claim at any time if it irrevocably waives its right to indemnity
         under this Section 14 with respect to such Third Party Claim.

                        (b) If the Indemnifying Party fails to notify the
         Indemnified Party within the Dispute Period that the Indemnifying Party
         desires to defend the Third Party Claim pursuant to Section 14C(i), or
         if the Indemnifying Party gives such notice but fails to prosecute
         vigorously and diligently or settle the Third Party Claim, or if the
         Indemnifying Party fails to give any notice whatsoever within the
         Dispute Period, then the Indemnified Party will have the right to
         defend, at the sole cost and expense of the Indemnifying Party, the
         Third Party Claim by all appropriate proceedings, which proceedings
         will be prosecuted by the Indemnified Party in a reasonable manner and
         in good faith or will be settled at the discretion of the Indemnified
         Party (with the consent of the 


<PAGE>


         Indemnifying Party, which consent will not be unreasonably withheld).
         The Indemnified Party will have full control of such defense and
         proceedings, including any compromise or settlement thereof; provided,
         however, that if requested by the Indemnified Party, the Indemnifying
         Party will, at the sole cost and expense of the Indemnifying Party,
         provide reasonable cooperation to the Indemnified Party and its
         counsel in contesting any Third Party Claim which the Indemnified
         Party is contesting. Notwithstanding the foregoing provisions of this
         clause (b), if the Indemnifying Party has notified the Indemnified
         Party within the Dispute Period that the Indemnifying Party disputes
         its liability hereunder to the Indemnified Party with respect to such
         Third Party Claim and if such dispute is resolved in favor of the
         Indemnifying Party in the manner provided in clause (c) below, the
         Indemnifying Party will not be required to bear the costs and expenses
         of the Indemnified Party's defense pursuant to this clause (b) or of
         the Indemnifying Party's participation therein at the Indemnified
         Party's request, and the Indemnified Party will reimburse the
         Indemnifying Party in full for all reasonable costs and expenses
         incurred by the Indemnifying Party in connection with such litigation.
         The Indemnifying Party may participate in, but not control, any
         defense or settlement controlled by the Indemnified Party pursuant to
         this clause (b), and the Indemnifying Party will bear its own costs
         and expenses with respect to such participation.

                        (c) If the Indemnifying Party notifies the Indemnified
         Party that it does not dispute its liability to the Indemnified Party
         with respect to the Third Party Claim under this Section 14 or fails to
         notify the Indemnified Party within the Dispute Period whether the
         Indemnifying Party disputes its liability to the Indemnified Party with
         respect to such Third Party Claim, the Loss in the amount specified in
         the Claim Notice will be conclusively deemed a liability of the
         Indemnifying Party under this Section 14 and the Indemnifying Party
         shall pay the amount of such Loss to the Indemnified Party on demand.
         If the Indemnifying Party has timely disputed its liability with
         respect to such claim, the Indemnifying Party and the Indemnified Party
         will proceed in good faith to negotiate a resolution of such dispute,
         and if not resolved through negotiations within the Resolution Period,
         such dispute shall be resolved by arbitration in accordance with
         paragraph (iii) of this Section 14C.

                       (ii) In the event any Indemnified Party should have a
claim under this Section 14C against any Indemnifying Party that does not
involve a Third Party Claim, the Indemnified Party shall deliver an Indemnity
Notice (as defined below) with reasonable promptness to the Indemnifying Party.
The failure by any Indemnified Party to give the Indemnity Notice shall not
impair such party's rights hereunder except to the extent that an Indemnifying
Party demonstrates that it has been irreparably prejudiced thereby. If the
Indemnifying Party notifies the Indemnified Party that it does not dispute the
claim described in such Indemnity Notice or fails to notify the Indemnified
Party within the Dispute Period whether the Indemnifying Party disputes the
claim described in such Indemnity Notice, the Loss in the amount specified in
the Indemnity Notice will be conclusively deemed a liability of the Indemnifying
Party under this Section 14 and the Indemnifying Party shall pay the amount of
such Loss to the Indemnified Party on demand. If the Indemnifying Party has
timely disputed its liability with respect to such claim, the Indemnifying Party
and the Indemnified Party will proceed in good faith to negotiate a resolution
of such dispute, and if not resolved through negotiations within the Resolution
Period, such dispute shall be resolved by arbitration in accordance with
paragraph (iii) of this Section 14C.

                       (iii) Any dispute submitted to arbitration pursuant to
this Section 14C shall be finally and conclusively determined by the decision of
a board of arbitration consisting of three (3) members (hereinafter sometimes
called the "Board of Arbitration") selected as hereinafter provided. Each of the
Indemnified Party and the Indemnifying Party shall select one (1) member and the
third member shall be selected by mutual agreement of the other members, or if
the other members fail to reach agreement on a third member within twenty (20)
days after their selection, such third member shall thereafter be selected by
the American Arbitration Association upon application made to it for such
purpose by the Indemnified 


<PAGE>


Party. The Board of Arbitration shall meet in New York City, New York or such
other place as a majority of the members of the Board of Arbitration determines
more appropriate, and shall reach and render a decision in writing (concurred in
by a majority of the members of the Board of Arbitration) with respect to the
amount, if any, which the Indemnifying Party is required to pay to the
Indemnified Party in respect of a claim filed by the Indemnified Party. In
connection with rendering its decisions, the Board of Arbitration shall adopt
and follow such rules and procedures as a majority of the members of the Board
of Arbitration deems necessary or appropriate. To the extent practical,
decisions of the Board of Arbitration shall be rendered no more than thirty (30)
calendar days following commencement of proceedings with respect thereto. The
Board of Arbitration shall cause its written decision to be delivered to the
Indemnified Party and the Indemnifying Party. Any decision made by the Board of
Arbitration (either prior to or after the expiration of such thirty (30)
calendar day period) shall be final, binding and conclusive on the Indemnified
Party and the Indemnifying Party and entitled to be enforced to the fullest
extent permitted by law and entered in any court of competent jurisdiction. Each
party to any arbitration shall bear its own expense in relation thereto,
including but not limited to such party's attorneys' fees, if any, and the

Unless otherwise specified, notices shall be deemed given when received, but if

                  I. Contributor acknowledges that (i) the computation of
taxable income of Acquiror is crucial in the determination of the taxable income
of REIT, (ii) REIT needs to be able to prepare accurate estimates of its taxable
income in order to monitor compliance with the requirement that it distribute
95% of its taxable income to its shareholders, and (iii) the depreciation of the
Properties and the required depreciation allocations under Section 704(c) of the
Code will materially impact the computation of Acquiror's and REIT's taxable
income. Accordingly, Contributor agrees that (i) prior to the expiration of the
Inspection Period, Contributor shall provide Acquiror with tax basis
computations and historical tax depreciation schedules updated through the
Closing Date for each Property; and (ii) prior to the expiration of the
Inspection Period, Contributor shall provide Acquiror with all data required to
perform depreciation allocations (as contemplated by Section 704(c) of the Code)
with respect to each Property and the OP Unit Recipient. Such data shall include
the tax basis allocable to the OP Unit Recipient for each Property. In addition,
Contributor acknowledges that, in the event repayment of any Assumed
Indebtedness triggers discharge of indebtedness income under the Code (and
particularly Section 61(a)(12) thereof), the Acquiror's Partnership Agreement
shall be amended to specially allocate all such income to Contributor.

                  J. Except as otherwise required by law or the rules of any
applicable securities exchange or national market system, so long as this
Agreement is in effect, Contributor will not, and will not permit any of its
Representatives to, issue or cause the publication of any press release or make
any other public announcement with respect to the transactions contemplated by
this Agreement without the consent of Acquiror, which consent shall not be
unreasonably withheld. Acquiror and Contributor will cooperate with each other
in the development and distribution of all press releases and other public
announcements 


<PAGE>


with respect to this Agreement and the transactions contemplated hereby, and
will furnish the other with drafts of any such releases and announcements as far
in advance as practicable.

                  K. This Agreement may be executed in any number of identical
counterparts, any or all of which may contain the signatures of fewer than all
of the parties but all of which shall be taken together as a single instrument.
Execution copies of this Agreement may also be exchanged by facsimile, and
facsimile signatures shall be treated as originals.

                  L. When the context so requires, the singular number shall
include the plural and the plural the singular, and the use of any gender shall
include all genders.

                  M. This Agreement may not be modified, discharged or changed
in any respect whatsoever, except by a further agreement in writing duly
executed by Contributor and Acquiror. However, any consent, waiver, approval or
authorization shall be effective if signed by the party granting or making such
consent, waiver, approval or authorization.

                  N. The invalidation or unenforceability in any particular
circumstance of any of the provisions of this Agreement shall in no way affect
any of the other provisions hereof, which shall remain in full force and effect.

                  O. The Properties being acquired by Acquiror pursuant to this
Agreement shall be transferred and conveyed on an "AS-IS" and "WHERE-IS" basis,
and WITH ALL FAULTS, except as otherwise expressly set forth in this Agreement
or in any document delivered by Contributor at Closing. Except as expressly set
forth in this Agreement or in any document delivered by Contributor at Closing,
Contributor has not made any representation or warranty as to the present or
future physical condition, value, presence/absence of hazardous or toxic
materials, financing status, leasing, operations, use, tax status, income and
expense or any other matter pertaining to the Properties.

OP Units (as defined below) having an aggregate value (based upon a market price
of $16.50 per share for the common stock of the REIT) of the sum of the amounts
described in clauses (i) and (ii) below (the "Total OP Unit Value"):

                        (i) For the Columbia Properties, (a) Thirty-Three
         Million Six Hundred Fifty-Three Thousand One Hundred Ninety-Eight and
         00/100 Dollars ($33,653,198.00); minus (b) the sum of all of the
         indebtedness of Contributor relating to the Columbia Properties
         (including unpaid principal and interest and any prepayment fees and
         related charges), as of the Closing Date (as defined below), under
         those certain mortgage loans more particularly described in Exhibit F
         attached to this Agreement (the "Columbia Existing Indebtedness");
         minus (c) any prorations described in Section 6C ("Prorations") and
         credited, as of the Closing Date, to Acquiror; plus (d) any Prorations
         credited, as of the Closing Date, to Contributor.

                       (ii) For the Airline Property, (a) Six Million Four
         Hundred Ninety Thousand One Hundred Sixty One and 00/100 Dollars
         ($6,490,161.00), minus (b) the sum of all of the indebtedness of
         Contributor relating to the Airline Property (including unpaid
         principal and interest and any prepayment fees and related charges), as
         of the Closing Date, under those certain mortgage loans more
         particularly described in Exhibit F attached to this Agreement (the
         "Airline Existing Indebtedness," and together with the Columbia
         Existing Indebtedness, the "Existing Indebtedness"); minus (c) any
         Prorations credited, as of the Closing Date, to Acquiror; plus (d) any
         Prorations credited, as of the Closing Date, to Contributor.

                      (iii) Notwithstanding the foregoing clauses (i) and (ii),
         the number of OP Units to be paid by Acquiror, without giving effect to
         any adjustment for Prorations discussed in clauses (i)(c), (i)(d),
         (ii)(c) and (ii)(d) above, shall not exceed 797,892 OP Units. If the
         calculation of the Contribution Consideration in accordance with the
         foregoing provisions would result in a fraction of an OP Unit being
         delivered to Contributor, then such fraction shall be rounded to the
         nearest whole number. The Properties are to be contributed to Acquiror
         subject to the corresponding items of Existing Indebtedness, which will
         either be assumed, refinanced or paid off by Acquiror immediately
         following the Closing.

                  C. Issuance of OP Units. Units of limited partnership interest
in Acquiror (the "OP Units") shall be issued and delivered in the names of and
for distribution to those recipients set forth in Exhibit G attached hereto (the
"OP Unit Recipients"). After the first anniversary of the Closing the OP Units
shall be convertible at any time or from time to time for shares ("Conversion
Shares") of the common stock, par value $.001 per share, of the REIT ("Stock")
on a one-for-one basis, or for cash as provided in and subject to the conditions
and restrictions contained in the Acquiror's Amended and Restated Agreement of
Limited Partnership dated as of December 12, 1997 (the "Partnership Agreement");
provided, however, that notwithstanding the foregoing, the OP Units (together
with the OP Units issued pursuant to the Northeastern Contribution Agreement)
may not be converted into Conversion Shares that in the aggregate represent more
than 19.9% of the total number of shares of Stock that are issued and
outstanding on the date on which the 



                                       3
<PAGE>


OP Units are issued to the OP Unit Recipients until and unless the requisite
approval from the REIT's stockholders is obtained prior to such conversion.
Acquiror agrees that it will use its commercially reasonable efforts to cause
the REIT to seek such stockholder approval, including presenting the issue, with
management's endorsement, to the REIT's, stockholders at the next annual or
special meeting of stockholders following the Closing, and to present the issue
at the next subsequent meeting if the necessary stockholder approval is not
obtained.

                  D. Transfer Restrictions. Each OP Unit Recipient, by his
execution and delivery of this Agreement, agrees that he may only sell,
transfer, assign, pledge or encumber, or otherwise convey, any or all of the OP
Units issued and delivered to him in connection with this transaction and, if
applicable, any Conversion Shares (any of the foregoing, a "Transfer") in strict
compliance with this Agreement, the Partnership Agreement, the charter documents
of the REIT, the registration and other provisions of the Securities Act of
1933, as amended, and the rules and regulations promulgated thereunder (the
"Securities Act"), any state securities laws, and the rules of the AMEX, in each
case as may be applicable (collectively, the "Transfer Requirements"). Each OP
Unit Recipient shall have the registration rights with respect to the Conversion
Shares issuable in respect of its OP Units set forth in the OP Unit Recipient
Agreement (as defined below). The provisions of this paragraph shall survive the
Closing.

                  E. Lock-Up Period. Each OP Unit Recipient agrees that for a
period of twelve (12) months following the Closing (the "Lock-Up Period") he
shall not, nor shall he seek to, in any way or to any extent, directly or
indirectly exchange or convert (pursuant to the Partnership Agreement or
otherwise), offer, sell, offer or contract to sell, transfer, assign, grant any
option for the sale of, pledge (without Acquiror's consent which will not be
unreasonably withheld, and except for pledges to those pledgees listed in
Schedule 3E) or encumber, or otherwise transfer, convey, or dispose of, any or
all of the OP Units delivered to the OP Unit Recipient at the Closing or the
Conversion Shares in respect thereof; provided that transfers may be made,
subject to the restrictions hereof and under the Partnership Agreement, to
Permitted Transferees (as defined below) who shall remain subject to the
restrictions hereunder. In addition, each OP Unit Recipient further agrees that
following the expiration of the Lock-Up Period, not more than twenty-five
percent (25%) of the OP Units delivered to such OP Unit Recipient at the Closing
or Conversion Shares in respect thereof may be sold in the three-month period
following the initial Lock-Up Period, and an additional twenty-five percent
(25%) of such OP Units and Conversion Shares may be sold in each three-month
period thereafter (so that all OP Units and Conversion Shares may be sold after
the second (2nd) anniversary of the Closing Date). The term "Permitted
Transferee" with respect to any OP Unit Recipient shall mean any other OP Unit
Recipient or such recipient's spouse; a parent or lineal descendant (including
an adopted child) of a parent, or the spouse of a lineal descendant of a parent;
a trustee, guardian or custodian for, or an executor, administrator or other
legal representative of the estate of, such recipient, or a trustee, guardian or
custodian for a Permitted Transferee of such recipient; the trustee of a trust
(including a voting trust) for the benefit of such recipient; and a corporation,
partnership or other entity of which such recipient and Permitted Transferees of
such recipient are the beneficial owners of a majority in voting power of the
equity; but only in each of the foregoing cases, who (a) is an Accredited
Investor (as defined in Rule 501 under the Securities Act); and (b) agrees in
writing in an instrument reasonably acceptable to Acquiror to be bound by the
restrictions on transfer of the OP Units and Conversion Shares contained in this
Agreement and by the obligations contained in the indemnification provisions
contained in Section 14 of this Agreement. The provisions of this paragraph
shall survive the Closing. Each OP Unit Recipient shall execute and deliver to
Acquiror at Closing a letter to the effect of the foregoing, in form and
substance reasonably satisfactory to Acquiror.

                  F. Right of First Refusal/First Offer on Sale of OP Units.
Each OP Unit Recipient agrees that Acquiror shall have a right of first refusal
and a right of first offer with respect to OP Units that 



                                       4
<PAGE>


such OP Unit Recipient seeks to sell, as provided in an agreement to be
delivered by each OP Unit Recipient at Closing substantially in the form of
Exhibit H attached hereto (the "OP Unit Recipient Agreement").

                  G. Right of First Refusal/First Offer on Sale of Future
Development at Airline Drive.

                        (i) From and after the Closing Date and continuing up to
         and including the fifth (5th) anniversary thereof, Acquiror shall have
         a continuing right of first refusal to purchase any building(s)
         developed or acquired by Contributor and/or any of the OP Unit
         Recipients (collectively, "Owner") after the date hereof and located at
         Airline Drive, subject to Section 3G(iii) below, as follows: In the
         event Owner receives a bona fide third party offer to purchase (whether
         by transfer of fee simple interest, a ground lease, sale of an interest
         in Owner, an installment sale, or otherwise) one or more buildings and
         related land and facilities located at Airline Drive (the "First
         Refusal Buildings"), and Owner desires to accept such offer, Owner
         shall provide written notice to Acquiror within ten (10) days after
         Owner's receipt of such offer, including a copy of the offer and
         specifying the purchase price, terms of payment, identity of the First
         Refusal Building(s) and other material terms and conditions of such
         third party offer. Acquiror or its nominee shall be entitled for a
         period of fifteen (15) days after the date of receipt of such notice of
         a third party offer to exercise its right to purchase such First
         Refusal Building(s) in accordance with the terms and conditions
         specified in the offer as set forth in Owner's written notice to
         Acquiror. Acquiror shall not have the right of first refusal for less
         than all of the First Refusal Building(s) identified in a third party
         offer for two or more of the First Refusal Building(s) unless such
         third party offeror shall have alternative rights to purchase less than
         all of the First Refusal Building(s) identified in the offer at prices
         and pursuant to terms set forth in the offer, in which case, Acquiror's
         right of first refusal shall correspond to the third party offeror's
         alternative rights. Any elimination of First Refusal Buildings from the
         original offer or addition of one or more First Refusal Buildings to
         the original offer shall constitute a new offer for purposes of this
         paragraph, for which Acquiror shall have the corresponding right of
         first refusal, provided that the terms for such elimination or addition
         were not part of the original offer submitted to Acquiror for right of
         first refusal consideration. If Acquiror exercises its right to
         purchase the interest offered for sale, Owner and Acquiror shall
         consummate the purchase and sale within a period of ninety (90) days
         after the date Acquiror provides written notice to Owner exercising its
         right to purchase, unless such closing is delayed for reasons beyond
         the reasonable control of the parties. In the event Acquiror fails to
         exercise its right of first refusal as set forth in this paragraph,
         Owner shall be free to sell the First Refusal Building(s) to such third
         party offer pursuant to the terms and conditions of the offer;
         provided, however, that in the event a binding contract of sale for
         such First Refusal Building(s) is not executed between Owner and such
         third party offeror within 180 days after the expiration of Acquiror's
         fifteen-day right of first refusal period, or the purchase price is
         reduced by 3% or more or the other terms and conditions of such third
         party offer are modified in any other material respect, then Acquiror
         shall again have its right of first refusal to acquire such First
         Refusal Building(s) as set forth in this paragraph, and Owner and
         Acquiror shall again comply with the requirements hereof. For purposes
         of this paragraph, a bona fide third party offer shall include, without
         limitation an executed letter of intent so long as such letter of
         intent specifies the purchase price, terms of payment, identity of the
         First Refusal Building(s) and other material terms and conditions.

                       (ii) From and after the Closing Date and continuing up to
         and including the fifth (5th) anniversary thereof, Acquiror shall have
         a continuing right of first offer to purchase any building(s) developed
         or acquired by Owner after the date hereof and located at Airline
         Drive, subject to Section 3G(iii) below, as follows: In the event Owner
         desires to sell or seeks to sell 



                                       5
<PAGE>


         (whether by transfer of fee simple interest, a ground lease, sale of
         an interest in Owner, an installment sale, or otherwise) one or more
         buildings and related land and facilities located at Airline Drive
         (the "First Offer Buildings"), Owner shall provide written notice to
         Acquiror specifying the purchase price, terms of payment, identity of
         the First Offer Building(s) and other material terms and conditions of
         the offer or sale (the "Sale Notice"). Acquiror or its nominee shall
         have the option (the "Purchase Option"), to be exercised by written
         notice given to Owner within thirty (30) days after Acquiror's receipt
         of the Sale Notice (the "Exercise Period"), to purchase the First
         Offer Buildings from Owner on the terms specified in the Sale Notice.
         If Acquiror exercises its Purchase Option, Owner and Acquiror shall
         consummate the purchase and sale within a period of ninety (90) days
         after the date Acquiror provides written notice to Owner exercising
         its right to purchase, unless such closing is delayed for reasons
         beyond the reasonable control of the parties. In the event Acquiror
         fails to exercise its Purchase Option as set forth in this paragraph,
         Owner shall be free to sell the First Offer Building(s) to third
         parties pursuant to the terms and conditions of the offer to Acquiror;
         provided, however, that in the event a binding contract of sale for
         such First Offer Building(s) is not executed between Owner and such
         third party offeror within 180 days after the expiration of the
         Exercise Period, or the purchase price is reduced by 3% or more or the
         other terms and conditions of such third party offer are modified in
         any other material respect, then Acquiror shall again have its right
         of first offer to acquire such First Offer Building(s) as set forth in
         this paragraph, and Owner and Acquiror shall again comply with the
         requirements hereof. For purposes of this paragraph, a bona fide third
         party offer shall include, without limitation an executed letter of
         intent so long as such letter of intent specifies the purchase price,
         terms of payment, identity of the First Offer Building(s) and other
         material terms and conditions.

                      (iii) Notwithstanding the foregoing right of first refusal
         and right of first offer, such rights shall not apply to First Refusal
         Buildings or First Offer Buildings in instances where Owner either
         receives bona fide offers from, or proposes to sell to, potential
         purchasers or potential developers who would also be, or whose
         affiliate would be, the tenant in the building(s) proposed to be built
         on such land.

                  H. Tax Matters. During the period commencing on the Closing
Date and expiring on the first (1st) anniversary of the Closing Date, Acquiror
shall not sell or make any other voluntary disposition (other than through a
deed in lieu of foreclosure, a foreclosure action, or an act of eminent domain)
of any of the Properties. Thereafter, during the period expiring on the earlier
of (i) the seventh (7th) anniversary of the Closing Date, or (ii) the sale or
conversion by the OP Unit Recipients of OP Units representing in the aggregate
70% of all OP Units delivered to them at the Closing: in connection with the
sale of any or all of the Properties, Acquiror shall use commercially reasonable
efforts to enter into a transaction that will qualify for non-recognition of
gain under the Internal Revenue Code of 1986, as amended (the "Code"), whether
by means of an exchange contemplated under Code Sections 351, 354, 355, 368,
721, 1031, 1033 or otherwise. Notwithstanding the foregoing, in the event of
catastrophic damage to any or all of the Properties by an act of God (e.g.,
hurricane or tornado), Acquiror shall have the right to sell any or all of the
Properties affected thereby without regard to the foregoing. Pursuant to Section
5.4 of the Partnership Agreement, Acquiror shall elect to use the "traditional
method" set forth in Regulation Section 1.704-3(b) with respect to the
Properties.

                  I. Board Seat. Acquiror shall take all such actions necessary
to cause the nomination of Francesco Galesi for election to the Board of
Directors of the REIT, with an initial term of not less than two (2) years nor
more than three (3) years, at the REIT's next annual or special meeting of the
REIT's stockholders, such nominee to take office effective upon such election.



                                       6
<PAGE>


                  J. Allocation of Contribution Consideration. Prior to the
Closing and if requested by Acquiror, Acquiror and Contributor shall use
commercially reasonable efforts to agree in writing upon the allocation of the
Contribution Consideration among the Land, the Improvements and the tangible
Personal Property.

                  K. Further Assurances. Each party hereto will execute such
further documents and instruments and take such further actions as may be
reasonably requested by one or more of the others to consummate the transactions
contemplated hereby, to vest Acquiror with full right, title and interest in and
to the Properties or to effect the other purposes of this Agreement.

                  L. Notification if Representations and Warranties Untrue.
During the Inspection Period (as defined below), Acquiror shall notify
Contributor upon discovery that any representation or warranty of Contributor
contained in this Agreement is untrue or incorrect, and Contributor shall notify
Acquiror upon discovery that any representation or warranty of Acquiror
contained in this Agreement is untrue or incorrect.

         4.       OPERATION OF PROPERTIES THROUGH CLOSING

                  Through the Closing Date, Contributor shall:

                  A. Except as otherwise provided for in this Agreement, manage
and operate the Properties only in and shall not take any actions except in
accordance with Contributor's usual and ordinary course of business consistent
with past practices and keep the Land, the Improvements and the tangible
Personal Property in their current condition and repair, ordinary wear and tear
excepted.

                  B. Not extend or otherwise renew any Lease or Service Contract
without the prior written consent of Acquiror, which consent shall not be
unreasonably withheld.

                  C. Not cancel, modify or amend any Lease or Service Contact or
institute any rent increases without the prior written consent of Acquiror,
which consent shall not be unreasonably withheld.

                  D. Not enter into any new Lease or new Service Contract
without the prior written consent of Acquiror, which consent shall not be
unreasonably withheld.

                  E. Neither take any action nor omit to take any action that
would render or allow title to the Properties to be nonconforming to the
requirements of this Agreement.

                  F. Provide Acquiror, upon reasonable advance notice, with such
access to the Properties as is reasonably necessary for it to inspect same to
assure that Contributor is complying with the requirements of this Section 4.

                  G. Promptly deliver to Acquiror copies of any operating
statements for the Properties that come into the possession or control of
Contributor for any period(s) including the period between the date of this
Agreement and the Closing Date.



                                       7
<PAGE>


                  H. Not sell, lease, grant any security interest in, pledge,
encumber, dispose of, finance or refinance any indebtedness in respect of, any
of the Properties without the prior written consent of Acquiror, which consent
shall not be unreasonably withheld.

         5.       STATUS OF TITLE TO PROPERTIES

                  A. State of Title. Contributor shall convey the Properties to
Acquiror or Acquiror's designee subsidiary by bargain and sale deeds without
covenants against grantor's acts in recordable form (the "Deeds"), and title to
the Properties shall be free and clear of all liens and encumbrances and shall
be subject only to: (i) those covenants, conditions and restrictions of record
which are reviewed and approved by Acquiror within the Inspection Period, (ii)
rights of tenants under the Leases, as tenants only, (iii) general real estate
taxes for the year in which the Closing occurs and subsequent years, not yet
delinquent and (iv) those certain mortgages securing payment of the Existing
Indebtedness and more particularly described in Exhibit I attached to this
Agreement (the "Existing Mortgages") (the above enumerated exceptions being
hereinafter collectively referred to as the "Permitted Exceptions").

                  B. Preliminary Evidence of Title. As specified below,
Contributor shall furnish Acquiror with or Acquiror shall obtain at Acquiror's
expense the following documents to evidence the condition of Contributor's title
to the Properties:

                        (i) Acquiror shall obtain for each of the Properties, at
         Acquiror's expense, a commitment (the "Title Commitment") for an ALTA
         1992 Owner's Title Insurance Policy proposing to insure Acquiror or
         Acquiror's designee and committing to insure title to the Properties in
         such amounts as Acquiror deems appropriate, issued through a title
         insurer to be selected by Acquiror (the "Title Insurer"), and
         irrevocable for at least six (6) months. The Title Commitment shall
         show fee simple title to the Properties vested in Contributor. The
         Owner's Title Insurance Policy to be issued to Acquiror at the Closing
         pursuant to the corresponding Title Commitment shall be at regular
         rates and contain an extended coverage endorsement over the so-called
         general or standard exceptions that are a part of the printed form of
         the policy, an ALTA Form 103.7 access endorsement, coverage insuring
         any easements for utilities servicing the Properties that do not
         connect to the Properties from a public street, and such other
         endorsements as counsel for Acquiror shall reasonably deem appropriate.

                       (ii) Within fifteen (15) days after the date of this
         Agreement, Contributor shall furnish to Acquiror, at Acquiror's
         expense, written results of searches (the "UCC Searches") conducted by
         a private service reasonably acceptable to Acquiror of the records of
         the County Recorder of the County and Secretary of State of the State
         in which the Properties are located for Uniform Commercial Code
         Financing Statements, tax liens and the like in the name of
         Contributor, the Properties and any other name or location reasonably
         requested by Acquiror.

                      (iii) Acquiror shall obtain, at Acquiror's expense, a
         current "as-built" plat of survey (the "Survey") for each of the
         Properties dated after the date of this Agreement, certified to
         Acquiror, the REIT and the Title Insurer (and such other persons or
         entities as Acquiror may designate) by a surveyor registered in the
         State in which the Properties are located as having been prepared (i)
         in accordance with the "Minimum Standard Detail Requirements for
         ALTA/ACSM Land Title Surveys," jointly established and adopted by the
         American Land Title Association ("ALTA") and the American Congress on
         Surveying and Mapping ("ACSM") in 1992, and including items 1 through 5
         (excluding for Table A5 any information with respect to elevations),
         6-



                                       8
<PAGE>


         11 and 13 of Table A thereof, and (ii) pursuant to the Accuracy
         Standards (as adopted by ALTA and ACSM and in effect on the date of
         such certification) of an "Urban" Survey (as defined therein). Each
         Survey shall also contain the surveyor's certification that, among
         other things, the Properties are not located in any area designated by
         any governmental agency or authority as being a flood-prone or
         flood-risk area (whether pursuant to the Flood Disaster Act of 1973,
         as amended, or otherwise), and that the requirements of the National
         Flood Insurance Program are not applicable to the Properties.

                  C. Title Defects. If the Title Commitment, the UCC Searches or
any Survey (or any revision or update of any of them) discloses exceptions to
title other than Permitted Exceptions or any other title or survey matter which
does not conform to the requirements of this Agreement, Acquiror shall so notify
Contributor and Contributor shall have fifteen (15) days after the date of
Contributor's receipt of such notice to have each such unpermitted exception to
title removed or to correct each such other matter, in each case to the
reasonable satisfaction of Acquiror. If within the time specified Contributor
fails to have each such unpermitted exception removed or to correct each such
other matter as aforesaid, Acquiror may, at its option, which option must be
selected by Acquiror within ten (10) days after the expiration of Contributor's

                  Contributor;

                           (g) an assignment, in form and substance reasonably
                  satisfactory to Acquiror, pursuant to which Contributor

                  by the general partner or managing member, as the case may be,
                  of each Contributor, certifying to Acquiror that the
                  representations and warranties of Contributor contained in
                  this Agreement are true and correct as of the Closing Date;

                           (n) notices to parties to Service Contracts that are

                  limitation, the currently effective certificate(s) of
                  occupancy for the Properties, and such other governmental or
                  regulatory approvals issued to Contributor with respect to the
                  Properties).

                       (ii) Acquiror. Not less than five (5) business days prior
         to the Closing Date, Acquiror shall deliver to Contributor a copy of
         each of the following items (the original of each to be executed if
         necessary and delivered to Contributor at the Closing):

                           (a) the Assignment of Leases and the Assignment of

                  transaction contemplated hereby.

                      (iii) Form. Except to the extent attached to this

                  C.       Closing Prorations and Adjustments.

                        (i) A statement of prorations and adjustments shall be
         prepared by Acquiror in conformity with the provisions of this
         Agreement and submitted to Contributor for review not less than three
         (3) business days prior to the Closing Date. For purposes of
         prorations, Acquiror shall be deemed the owner of the Properties on the
         Closing Date. In addition to prorations and adjustments that may
         otherwise be provided for in this Agreement, the following items are to
         be prorated or adjusted (as the case requires) as of the Closing Date:

                           (a) the full amount of the security and other
                  deposits paid under the Leases, 



                                       11
<PAGE>


                  together with interest thereon if required by law or under
                  the Leases, shall be credited to Acquiror;

                           (b) To the extent such charges are not billed
                  directly to Tenants, water, electricity, sewer, gas, telephone
                  and other utility charges shall be prorated based, to the
                  extent practicable, on final meter readings and final
                  invoices, or, in the event final readings and invoices are not
                  available, based on the most currently available billing
                  information, and reprorated upon issuance of final utility
                  bills;

                           (c) Amounts paid or payable under any Service
                  Contracts being assigned to Acquiror shall be prorated based,
                  to the extent practicable, on final invoices or, in the event
                  final invoices are not available, based on the most currently
                  available billing information, and reprorated upon issuance of
                  final invoices;

                           (d) All real estate, personal property and ad valorem
                  taxes applicable to the Properties and levied with respect to
                  calendar year 1998 shall be prorated on an accrual basis, as
                  of the Closing Date, utilizing the actual final Tax Bills for
                  the Properties for 1997 (or 1998 if available) adjusted for
                  any announced changes in rates of taxation. Prior to or at
                  Closing, Contributor shall pay or have paid all Tax Bills that
                  are due and payable prior to or on the Closing Date and shall
                  furnish evidence of such payment to Acquiror and the Title
                  Company. Each party's respective obligations to reprorate real
                  estate taxes shall survive the Closing and shall not merge
                  into any instrument of conveyance delivered at Closing. The
                  taxes to be prorated (i.e., county, school, city) for each
                  Property and the billing and accrual schedule for each such
                  tax are set forth in Exhibit J;

                           (e) All assessments, general or special, shall be
                  prorated as of the Closing Date on a "due date" basis such
                  that the Contributor shall be responsible for any installments
                  of assessments which are first due or payable prior to the
                  Closing Date and Acquiror shall be responsible for any
                  installments of assessments which are first due or payable on
                  or after the Closing Date;

                           (f) Commissions of leasing and rental agents for any
                  Lease entered into as of or prior to the Closing Date that are
                  due and payable at or prior to the Closing Date, whether with
                  respect to base lease term, future expansions, renewals, or
                  otherwise, shall be paid in full at or prior to Closing by the
                  Contributor, without contribution or proration from Acquiror;

                           (g) All Base Rents (as defined below) and other
                  charges actually received, including, without limitation, all
                  Additional Rent (as defined below), shall be prorated at
                  Closing. At the time(s) of final calculation and collection
                  from tenants of Additional Rent for 1998, there shall be a
                  re-proration between Acquiror and the Contributor as to
                  Additional Rent adjustments, which re-proration shall be paid
                  upon Acquiror's presentation of its final accounting to the
                  Contributor, certified as to accuracy by Acquiror. The party's
                  respective obligations to reprorate Additional Rent shall
                  survive the Closing and shall not merge into any instrument of
                  conveyance delivered at Closing. At the Closing, no
                  "Delinquent Rents" (rents or other charges which are due and
                  owing as of the Closing) shall be prorated in favor of the
                  Contributor. Notwithstanding the foregoing, Acquiror shall use
                  reasonable efforts after the Closing Date to collect any
                  Delinquent Rents due to the Contributor from tenants. Further,
                  after the Closing Date, the Contributor shall 



                                       12
<PAGE>


                  continue to have the right, enforceable at its sole expense,
                  to pursue legal action against any tenant (and any
                  guarantors) who have defaulted, prior to the Closing Date,
                  under a Lease; provided, however, that the Contributor gives
                  Acquiror advance written notice of its intent to pursue such
                  action and further provided that the Contributor shall have
                  no right to terminate any Lease (or any right to dispossess
                  any tenant thereunder). All rents and other charges received
                  from any tenant after the Closing by and for the benefit of
                  Acquiror shall be applied, first, against current and past
                  due rental obligations owed to, or for the benefit of,
                  Acquiror with respect to those rental obligations accruing
                  subsequent to the Closing Date (including, but not limited
                  to, obligations to replenish any security deposit withdrawal
                  by the Contributor or Acquiror), or any obligations accruing
                  prior to the Closing Date that the Contributor does not pay
                  or for which Acquiror does not receive a credit at Closing,
                  and second, any excess shall be delivered to the
                  Contributor, but only to the extent of Delinquent Rents owed
                  to, and for the benefit of, the Contributor for the period
                  prior to the Closing Date (in no event, however, shall any
                  sums be paid to the Contributor to the extent it has been
                  previously reimbursed for such default out of any security
                  deposit);

                           (h) The Contributor and Acquiror acknowledge that
                  various of the Properties may contain certain vacancies as of
                  the date of this Agreement and all such current vacancies are
                  reflected on the Rent Roll (the "Vacancies"). If a new lease
                  for any such Vacancy ("Vacancy Lease") is executed prior to
                  Closing and the terms of such Vacancy Lease have been approved
                  by Acquiror, then the applicable Contributor and Acquiror
                  shall each bear a pro rata share, of the tenant improvement
                  costs and brokerage commission attributable to the Vacancy
                  Lease (the "Vacancy Lease Costs"). The Contributor's
                  proportionate share of the Vacancy Lease Costs shall be based
                  on that portion of the Vacancy Lease's term that elapses prior
                  to Closing and Acquiror's proportionate share shall be based
                  on that portion of the Vacancy Lease's term that remains
                  unexpired as of the Closing Date. The Contributor shall pay
                  all Vacancy Lease Costs and Acquiror shall reimburse the
                  Contributor for its proportionate share of such Vacancy Lease
                  Costs by way of an adjustment in the Contribution
                  Consideration. In the event that this Agreement is terminated
                  prior to Closing, then Acquiror shall have no liability or
                  obligation with respect to any Vacancy Lease or any Vacancy
                  Lease Costs.

                           (i) Such other items that are customarily prorated in
                  transactions of this nature shall be ratably prorated.

                       (ii) For purposes of calculating prorations, Acquiror
         shall be deemed to be in title to the Properties, and therefore
         entitled to the income therefrom and responsible for the expenses
         thereof, for the entire Closing Date. All such prorations shall be made
         on the basis of the actual number of days of the year and month that
         shall have elapsed as of the Closing Date. Except with respect to
         general real estate and personal property taxes that are to be
         reprorated as aforesaid, any proration which must be estimated at the
         Closing shall be reprorated and finally adjusted within ninety (90)
         days after the Closing Date; otherwise all prorations shall be final.
         The provisions of the foregoing sentence shall survive the Closing.

                  D. Closing Costs. All transfer taxes, documentary stamps,
intangible taxes and similar taxes or charges and cure expenses shall be paid by
Contributor. All title insurance premiums, search fees, survey costs and
recording charges shall be paid by Acquiror. Contributor and Acquiror shall each
pay for one-half (1/2) of the escrow fees charged by the Escrowee. Each party
shall pay its own attorney's fees and all of its other expenses, except as
otherwise expressly set forth herein.

                  E. Possession. Upon consummation of the Closing, Contributor
shall deliver to Acquiror full and complete possession of the Properties,
subject only to the Permitted Exceptions.

         7.       CASUALTY, LOSS AND CONDEMNATION

                  If, prior to the Closing, the Properties or any part thereof
shall be condemned, or destroyed or materially damaged by fire or other casualty
(that is, damage or destruction in excess of One Hundred Thousand and 00/100
Dollars $100,000.00), Contributor shall immediately so notify Acquiror and
Acquiror shall have the option either to terminate this Agreement upon written
notice to Contributor or to consummate the transaction contemplated by this
Agreement notwithstanding such condemnation, destruction or material damage. If
Acquiror elects to consummate the transaction contemplated by this Agreement,
Acquiror shall be entitled to receive the condemnation proceeds or settle the
loss under all policies of insurance applicable to the destruction or damage and
receive the proceeds of insurance applicable thereto, and Contributor shall, at
the Closing and thereafter as necessary, execute and deliver to Acquiror all
required proofs of loss, assignments of claims and other similar items. If
Acquiror elects to terminate this Agreement, the Earnest Money shall be returned
to Acquiror by Escrowee, in which event this Agreement shall, without further
action of the parties, become null and void and neither party shall have any
rights or obligations under this Agreement. If there is any other damage or
destruction (that is, damage or destruction of One Hundred Thousand and 00/100
Dollars $100,000.00 or less) to the Properties or any part thereof, Contributor
shall either repair such damage prior to the Closing or, at Acquiror's option,
assign all insurance claims pertaining to such damage or destruction to Acquiror
by executing and delivering to Acquiror at the Closing and thereafter as
necessary all required proofs of loss, assignments of claims and other similar
items. If Acquiror elects to take an assignment of all insurance claims as
aforesaid, Acquiror shall receive at the Closing a credit against the
Contribution Consideration in an amount equal to any deductible(s) applicable
thereto.

         8.       REPRESENTATIONS AND WARRANTIES

                  A. Each Contributor represents and warrants, jointly and
severally, to Acquiror that the following are true, complete and correct as of
the date of this Agreement:

                        (i) Each Contributor is a general partnership or limited
         liability company duly organized, validly existing and in good standing
         under the laws of the state of its formation and has all requisite
         power and authority to own, lease and operate its properties and assets
         as they are now owned, leased and operated and to carry on its business
         as now conducted and presently proposed to be conducted. Each
         Contributor is duly qualified, licensed or admitted to do business and
         is in good standing in those jurisdictions in which the ownership, use,
         or leasing of its assets and properties, or the conduct or nature of
         its business makes such qualification, licensing or admission
         necessary, except for failures to be so qualified, licensed or admitted
         and in good standing that individually or in the aggregate would not
         materially adversely affect the Properties, assets, business,
         operations or condition (financial or otherwise) of such Contributor or
         the ability of Contributor to perform its obligations under this
         Agreement (a "Contributor Material Adverse Effect").

                       (ii) Contributor has full partnership or limited
         liability company, as the case may be, power and authority and each OP
         Unit Recipient has full legal right, capacity and power to enter into,
         execute and deliver this Agreement and to perform fully its obligations
         hereunder. The execution, delivery and performance by Contributor of
         this Agreement and the other documents to 



                                       14
<PAGE>


         be delivered by Contributor at Closing, and the consummation by
         Contributor of the transactions contemplated hereby and thereby have
         been duly and validly authorized by all necessary partnership or
         limited liability company, as the case may be, action on the part of
         Contributor and no other proceedings on the part of Contributor,
         including of its partners or members, as the case may be, are
         necessary to authorize the execution, delivery and performance by
         Contributor of this Agreement and the other documents to be delivered
         by Contributor at Closing and the consummation by Contributor of the
         transactions contemplated hereby and thereby. This Agreement has been
         duly executed and delivered by Contributor and each OP Unit Recipient
         and is a valid and binding obligation of Contributor and each OP Unit
         Recipient, enforceable against Contributor and each OP Unit Recipient
         in accordance with its terms.

                      (iii) Neither the execution and delivery of this Agreement
         by Contributor nor the performance by Contributor or the OP Unit
         Recipients of the transactions contemplated hereby will: (a) violate or
         conflict with any of the provisions of the partnership agreement,
         operating agreement or similar governing documents of Contributor; (b)
         except as would not have a Contributor Material Adverse Effect,
         violate, result in a breach of, conflict with, result in the
         acceleration of, or entitle any party to accelerate the maturity or the
         cancellation of the performance of any obligation under, or result in
         the creation or imposition of any Lien (as defined below) in or upon
         any of the Properties or assets of Contributor or constitute a default
         (or an event which might, with the passage of time or the giving of
         notice, or both, constitute a default) under any mortgage, indenture,
         deed of trust, lease, contract (including any Service Contract), loan
         or credit agreement, license or other instrument to which Contributor
         is a party or by which it or any of its assets may be bound or
         affected; or (c) except as would not have a Contributor Material
         Adverse Effect, violate or conflict with any provision of any statute,
         law, rule, regulation, code or ordinance or any judgment, decree,
         order, writ, permit or license (collectively, "Laws or Orders")
         applicable to Contributor, the Properties or assets of Contributor.
         Other than those which have been obtained or made prior to the date
         hereof, or as set forth in Schedule 8A(iii) attached to this Agreement,
         no consent or approval or action of, filing with or notice to any
         Governmental or Regulatory Authority (as defined below), any creditor,
         investor, partner, shareholder, or tenant-in-common of Contributor, or
         other party is necessary or required for the execution, delivery and
         performance by Contributor of this Agreement, or the consummation of
         the transactions contemplated hereby, other than such consents,
         approvals, actions, filings and notices which the failure to obtain or
         make, individually or in the aggregate, would not reasonably be
         expected to have a Contributor Material Adverse Effect.

                       (iv) To the best of Contributor's knowledge, it is not
         (a) in violation of its partnership agreement or operating agreement,
         as the case may be, (b) in default, and no event has occurred which,
         with notice or lapse of time or both, would constitute such a default,
         in the due performance or observance of any obligation, agreement,
         covenant or condition contained in any indenture, mortgage, deed of
         trust, loan or credit agreement, lease, contract (including any Service
         Contract) or other material agreement or instrument to which it is a
         party or by which it is bound or to which any of its properties or
         assets is subject or by which it, or any of them, may be materially
         affected, or (c) in violation or in conflict with any provision of any
         Laws or Orders applicable to Contributor, the Properties or assets of
         Contributor, except in the case of clauses (b) and (c) for such
         defaults, violations or conflicts that individually or in the aggregate
         would not reasonably be expected to have a Contributor Material Adverse
         Effect. To the best of Contributor's knowledge, (x) it is not in
         default under any of the documents, recorded or unrecorded, referred to
         in the Title Commitments for the Properties, and (y) Contributor nor
         any of the Properties is in default under any certificates of
         occupancy, licenses, permits, authorizations and approvals required by
         law or by any Governmental or Regulatory Authority having jurisdiction
         thereof in respect of Contributor or 



                                       15
<PAGE>


         its assets, the Properties, occupancy of the Properties or any present
         use thereof, except in the case of clauses (x) and (y), for such
         defaults that individually or in the aggregate would not reasonably be
         expected to have a Contributor Material Adverse Effect.

                        (v) Contributor is or at Closing will be the sole owner
         of, and has or will have good and marketable title to, the Properties
         free and clear of all liens, encumbrances, pledges, claims, security
         interests, demands, easements, covenants, conditions, restrictions and
         encroachments of any kind or nature (collectively, "Liens") other than
         Permitted Exceptions and liens that will be discharged or otherwise
         provided for at or prior to the Closing. The Contributor has not
         received any notice alleging that it is in default in compliance with
         the terms and provisions of any of the covenants, conditions,
         restrictions, rights-of-way or easements constituting one or more of
         the Permitted Exceptions. There are no development or other rights
         associated with any Property which are not being transferred to
         Acquiror under this Agreement or the documents contemplated by this
         Agreement.

                       (vi) To the best of Contributor's knowledge, the
         Improvements were constructed in a good, workmanlike and substantial
         manner, and in conformity with all rules, regulations, laws and
         ordinances applicable at the time of construction. Contributor has
         obtained and paid for all permits and certificates (including, without
         limitation, permits and certificates for water, plumbing, sewers and
         sewage treatment, electric, heating, ventilating, air conditioning,
         drainage and occupancy) required under any Federal, state or local law,
         ordinance, rule or regulation or by any governmental or
         quasi-governmental agency having jurisdiction over the Properties, and
         all of the same are in good standing. To the best of Contributor's
         knowledge, except as set forth in Schedule 8A(vi) attached to this
         Agreement, the Improvements and the tangible Personal Property are free
         from material defects; and the Properties and each part thereof have
         adequate drainage and contain not less than the minimum number of
         parking spaces required under applicable law. Except as set forth in
         Schedule 8A(vi) attached to this Agreement, each of the Properties
         abuts a public right-of-way, and the rights of ingress and egress with
         respect thereto as they currently exist are not restricted or limited
         in any manner.

                      (vii) All of Contributor's insurance policies are in full
         force and effect and Contributor is not in default with respect to any
         material provisions contained in any such policy. Neither Contributor,
         nor to the best of Contributor's knowledge, any agent of Contributor,
         has received from any insurer any notice with respect to any defects or
         inadequacies affecting all or any part of the Properties, any notice of
         cancellation or non-renewal of any such policy, or any notice that any
         insurance premiums will be materially increased in the future or that
         any insurance coverage under such policies will not be available in the
         future on substantially the same terms as now in effect.

                     (viii) Except as set forth in Schedule 8A(viii) attached to
         this Agreement, there is no judicial, municipal or administrative
         action, suit, arbitration, proceeding or investigation pending or, to
         the best of Contributor's knowledge, threatened against, relating to or
         affecting Contributor, its assets, the Properties or any part thereof
         before any court or governmental department, commission, board, agency
         or instrumentality, of the United States or any state, county, city or
         other political subdivision (a "Governmental or Regulatory Authority"),
         including, without limitation, proceedings for or involving collections
         (other than collections in the ordinary course of business),
         condemnation, eminent domain, alleged building code or environmental or
         zoning violations, or personal injuries or property damage alleged to
         have occurred at any of the Properties or by reason of the condition,
         use of, or operations on, such Property. No attachments, execution



                                       16
<PAGE>


         proceedings, assignments for the benefit of creditors, insolvency,
         bankruptcy or other similar proceedings are pending or, to the best of
         Contributor's knowledge, threatened against Contributor or any of the
         OP Unit Recipients.

                       (ix) Except as set forth in Schedule 8A(ix) attached to
         this Agreement, Contributor has not received from any Governmental
         Authority any written notice of zoning, building, fire, health code,
         environmental or other violations of applicable laws, rules, ordinances
         codes and regulations with respect to the Properties, or any part
         thereof.

                        (x) The Service Contracts comprise every contract,
         agreement, relationship and commitment, oral or written, other than the
         Leases and the Existing Mortgages that affect the Properties or to
         which Contributor is a party or by which it is bound, including,
         without limitation, all agreements relating to the management,
         construction, operation, maintenance or repair of any Property, the
         purchase of materials, supplies, equipment, machinery parts, products
         and services, and the lease of any property, real or personal. The
         Service Contracts are in full force and effect and have not been
         modified, amended or altered, in writing or otherwise. Neither
         Contributor nor, to the best of Contributor's knowledge, any other
         party is in default under the terms of any Service Contract. Except as
         otherwise noted on Exhibit C, each Service Contact is cancelable by
         Contributor (or its assignees or successors) without payment of any
         penalty upon not more than thirty (30) days prior notice.

                       (xi) Contributor has no patents, trademarks, servicemarks
         or trade names used in connection with the Properties, except for the
         name "Columbia Circle". To the best of Contributor's knowledge, the use
         of such names does not conflict with any rights of others with respect
         thereto. There is no claim pending or, to the best of Contributor's
         knowledge, threatened against Contributor with respect to alleged
         infringement of any patent, trademark, servicemark or trade name
         related to the Properties.

                      (xii) Without limiting any other warranty or
         representation of Contributor:

                           (a) there is no proceeding, plan, study or effort by
                  any governmental authority or agency pending, or to the best
                  of Contributor's knowledge, threatened, which in any way
                  affects or would affect the present use, improvements on, size
                  or zoning of any of the Properties (and Contributor has
                  received no notice from any governmental authority of any such
                  plan, study or effort), and there is no existing, or to the
                  best of Contributor's knowledge, proposed or contemplated plan
                  to widen, modify or realign any street or highway or any
                  existing, or to the best of Contributor's knowledge, proposed
                  or contemplated eminent domain proceedings that would affect
                  any of the Properties in any way whatsoever (and Contributor
                  has received no notice from any governmental authority of any
                  such existing, proposed or contemplated plan or proceedings);

                           (b) all laws, ordinances, codes, rules and
                  regulations of any Governmental and Regulatory Authority,
                  bearing on the construction, maintenance, repair or operation
                  of each of the Properties have been complied with by
                  Contributor at its sole cost, except the non-compliance with
                  which would not reasonably be expected to have a Material
                  Adverse Effect; and

                           (c) none of the Properties is located in any area
                  designated by any governmental authority or agency as being a
                  flood prone or flood risk area (whether 



                                       17
<PAGE>


                  pursuant to the Flood Disaster Act of 1973, as amended, or
                  otherwise) and the requirements of the National Flood
                  Insurance Program are not applicable to the Properties or
                  any part thereof.

                     (xiii) Except as set forth in Schedule 8A(xiii) attached to
         this Agreement, Contributor is not in default in respect of any of its
         obligations or liabilities pertaining to the Properties (including,
         without limitation, Contributor's obligations under any of the Leases),
         and there is no state of facts or circumstances or condition or event
         which, after notice or lapse of time, or both, would constitute or
         result in any such default.

                      (xiv)         With respect to the Leases:

                           (a) Except as set forth on the Rent Roll, each of the
                  Leases is in full force and effect, and has not been modified,
                  amended, or altered, in writing or otherwise. Contributor has
                  not received any notice of any material claim of any sort that
                  has been asserted by anyone adverse to the rights of
                  Contributor under any of the Leases, or affecting or
                  questioning the rights of Contributor of the continued
                  possession of the leased or subleased premises under any such
                  Lease. Except as set forth on the Rent Roll, each tenant is
                  legally required to pay all sums and perform all of its
                  obligations set forth in the Lease, without concessions,
                  abatements, offsets or other bases for relief or adjustment;

                           (b) Except as set forth on the Rent Roll, all
                  material obligations of the lessor under the Leases that
                  accrue to the date of Closing have been performed, including,
                  but not limited to, all required tenant improvements, cash or
                  other inducements, rent abatements or moratoria, installations
                  and construction (for which payment in full has been made or
                  will be made prior to Closing, or subject to proration
                  hereunder in all cases), and, to the best of Contributor's
                  knowledge, each tenant has unconditionally accepted lessor's
                  performance of such obligations. Except as set forth on the
                  Rent Roll, no tenant has asserted any offsets, defenses or
                  claims available against rent payable by it or other
                  performance or obligations otherwise due from it under any
                  Lease, which assertion remains outstanding;

                           (c) Except as set forth on the Rent Roll, no tenant
                  is currently in default under or is in arrears (for more than
                  30 days) in the payment of any sums or in the performance of
                  any monetary obligations required of it under its Lease, and
                  Contributor has no knowledge of any other default under any
                  such Lease;

                           (d) Except as set forth in the Rent Roll, during the
                  12-month period immediately preceding the date hereof: (i) no
                  tenant has, at any time, been more than 30 days delinquent in
                  its respective payment of any and all sums due under the terms
                  of its respective Lease; (ii) no tenant has requested that
                  Contributor provide that tenant with any reduction in the
                  tenant's monetary obligations under its Lease; (iii) no tenant
                  has requested that Contributor, in its capacity as landlord,
                  permit the tenant to sublease its leased premises, or assign
                  its Lease, or terminate its Lease on an accelerated basis;
                  (iv) Contributor has not "written off" any delinquent sums
                  owed by any tenant to satisfy its obligation to contribute to
                  the payment of real estate taxes, common area maintenance
                  charges, and insurance premiums; and (v) Contributor has not
                  had (nor is it currently engaged in) any dispute (whether of a
                  formal or an informal nature) with any tenant concerning that
                  tenant's obligations to make payments under the terms of its
                  Lease toward real estate taxes, insurance premiums and common
                  area maintenance charges or other 



                                       18
<PAGE>


                  charges imposed under its Lease;

                           (e) Except as set forth on the Rent Roll, Contributor
                  has not received any written notice from any tenant stating
                  that a petition in bankruptcy has been filed or is threatened
                  to be filed by or against it;

                           (f) Except with respect to security deposits, neither
                  base rent ("Base Rent"), nor regularly payable estimated
                  tenant contributions or operating expenses, insurance
                  premiums, real estate taxes, common area charges, and similar
                  or other "pass through" or non-base rent items including,
                  without limitation, cost-of-living or so-called "C.P.I." or
                  other such adjustments (collectively, "Additional Rent"), nor
                  any other material item payable by any tenant under any Lease
                  has been heretofore prepaid for more than one month;

                           (g) Except as set forth in the Rent Roll, to the best
                  of Contributor's knowledge, no guarantor(s) of any Lease has
                  been released or discharged, partially or fully, voluntarily
                  or involuntarily, or by operation of law, from any obligation
                  under or in connection with any Lease or any transaction

                  no brokers' commissions, finders' fees, or other charges
                  payable or to become payable to any third party on behalf of
                  Contributor in connection with any Lease, including, but not
                  limited to, any exercised option(s) to expand or renew;

                           (i) Each security deposit set forth on the Rent Roll
                  shall be assigned to Acquiror at the Closing (or Acquiror
                  shall receive a credit therefor). Except as set forth on the
                  Rent Roll, (i) no tenant or any other party has asserted any
                  claim (other than for customary refund at the expiration of a
                  Lease) to all or any part of any security deposit and (ii)
                  Contributor has not applied any portion of any security
                  deposit to the payment of any sums due from any tenant under a
                  Lease;

                           (j) Contributor shall pay (or Acquiror shall receive
                  a credit therefor), and retains sole and exclusive

                  Date connected with or arising out of the negotiation,
                  execution and delivery of the Leases, including, without
                  limitation, brokers' commissions (including those applicable,
                  if any, to future expansions or renewals by a tenant), leasing
                  fees and recording fees (as well as the cost of all tenant
                  improvements not required to be paid for by tenants);

                           (k) Except as set forth on the Rent Roll, no tenant
                  has, by virtue of its Lease or any other agreement or
                  understanding, any purchase option with respect to any of the
                  Properties, or any portion thereof, or any right of first
                  refusal to purchase any of the Properties, or a portion
                  thereof, whether triggered by the transactions contemplated by
                  this Agreement or by a subsequent sale of any of the
                  Properties or a portion thereof. Except as set forth on the
                  Rent Roll, no tenant has, by virtue of its Lease or any other
                  agreement or understanding any of the following (i) the option
                  to terminate its Lease prior to the stated expiration date and
                  (ii) the option to reduce the rentable space at any of the
                  Properties that such tenant is currently occupying; and

                           (l) Except as set forth on the Rent Roll: (i) to the
                  best of Contributor's 



                                       19

                  knowledge, no tenant has sublet its leased premises; and
                  (ii) there are no outstanding requests from any tenant to
                  Contributor, requesting any consent to an assignment of the
                  tenant's Lease or to a sublease of all or some portion of a
                  tenant's leased premises.

                       (xv) Except as set forth in Schedule 8A(xv) attached to
         this Agreement, the Properties have been fully valued and assessed for
         property tax purposes. Except as set forth in Schedule 8A(xv) attached
         to this Agreement, there are no general or special assessments
         applicable to the Properties or any part thereof. The bill or bills
         issued for the years 1994, 1995, 1996 and 1997, for all real estate
         taxes and personal property taxes and copies of any and all notices
         pertaining to real estate taxes or assessments applicable to the
         Properties (the "Tax Bills") (and to Contributor's knowledge, the only
         real estate tax bills applicable to the Properties) have been delivered
         to Acquiror. Except as set forth in Schedule 8A(xv) attached to this
         Agreement, Contributor has not received any notice of any proposed or
         actual increase in the assessed valuation of or rate of taxation of any
         or all of the Properties from that reflected in the most recent Tax
         Bills. Except as set forth in Schedule 8A(xv) attached to this
         Agreement, there is not now pending, and Contributor agrees that it
         will not, without the prior written consent of Acquiror (which consent
         shall not be unreasonably withheld or delayed), institute prior to the
         Closing Date, any proceeding or application for a reduction in the real
         estate tax assessment of any of the Properties or any other relief for
         any tax year. Other than the amounts disclosed by the Tax Bills, no
         other real estate taxes have been, or to Contributor's knowledge, will
         be, assessed against the Properties, or any portion thereof, in respect
         of the year 1997 or any prior year, and no special assessments of any
         kind (special, bond or otherwise) are or have been levied against the
         Properties, or any portion thereof, that are outstanding or unpaid,
         and, to Contributor's knowledge, none will be levied prior to Closing.
         Contributor has not entered into any agreements with attorneys or,
         consultants or other parties with respect to real estate taxes
         applicable to any of the Properties that will be binding on Acquiror
         after the Closing.

                      (xvi) Contributor has prepared and timely filed all tax
         returns required to be filed on or before the date hereof with respect
         to the Properties, which tax returns are true, correct and complete in
         all material respects. Contributor has paid or made provision for the
         payment of all taxes with respect to the Properties that are due or
         claimed to be due from it on or before the date hereof by any
         governmental taxing authority. No federal, state, local or foreign
         taxing authority has asserted any tax deficiency, lien, interest or
         penalty or other assessment against the Properties or Contributor which
         has not been paid and there is no pending audit or inquiry from any
         federal, state, local or foreign tax authority relating to the
         Properties or Contributor that may be expected to result in a tax
         deficiency, lien interest or other assessment against the Properties.

                     (xvii) The Personal Property is all of the personal
         property owned by Contributor and used in the operation of the
         Properties. Except as set forth in Schedule 8A(xvii) attached to this
         Agreement, Contributor has or at Closing will have good title to the
         Personal Property, free and clear of any Liens. All such Personal
         Property is in good working condition, free of material defects, normal
         wear and tear excepted.

                    (xviii) This Agreement and all other documents and
         agreements executed by Contributor in connection with the transaction
         that is the subject of this Agreement (collectively, the "Contributor's
         Documents") are binding on Contributor and enforceable against
         Contributor in accordance with their respective terms, subject to
         bankruptcy and similar laws affecting the remedies or recourse of
         creditors generally and general principles of equity.

                      (xix) All financial information regarding the Properties
         furnished by Contributor to Acquiror is true, complete and correct; has
         been compiled in accordance with generally accepted accounting
         principles and accurately set forth in all material respects the
         results of the operations of the Properties for the periods covered.

                       (xx) Contributor has no employees. All management
         contracts pertaining to the Properties will be terminated as of the
         Closing.

                      (xxi) All utilities (including, without limitation, gas,
         electricity, telephone, water and sanitary and storm sewers) have been
         completed to the lot lines of the Land, are connected to the
         Improvements as necessary, and all connection, hook-up, tap fees and
         the like have been paid.

                     (xxii) The Existing Mortgages constitute all of the
         mortgages or deeds of trust presently encumbering the Properties or any
         portion thereof. Contributor has complied with (and, prior to Closing,
         shall continue to comply with) in all material respects the terms of,
         and all notices or correspondence received from the holder of, the
         promissory notes evidencing the loans secured by the Existing Mortgages
         (the "Existing Notes"). Contributor has paid (and, at all times prior
         to Closing, shall pay), when and as due, all sums due under the
         Existing Mortgages, the Existing Notes and all other loan documents
         securing the Existing Notes (the "Other Loan Documents"). The Existing
         Notes, the Existing Mortgages and the Other Loan Documents are in full
         force and effect, and Contributor has not received any notice of a
         default thereunder that remains outstanding. Contributor has delivered
         to Acquiror true, complete and accurate copies of the Existing Notes,
         the Existing Mortgages and the Other Loan Documents. Except as set
         forth in Schedule 8A(xxii) attached to this Agreement, the indebtedness
         evidenced by the Existing Notes may be prepaid, in full, on the Closing
         Date without imposition of any penalty or premium.

                    (xxiii) No representation or warranty made by Contributor in
         this Agreement, no exhibit attached hereto with respect to the
         Properties, and no schedule contained in this Agreement contains any
         untrue statement of a material fact, or omits to state a material fact
         necessary in order to make the statements contained therein not
         misleading. All items delivered by or on behalf of Contributor pursuant
         to this Agreement are true, accurate, correct and complete in all
         material respects, and fairly present the information set forth in a
         manner that is not misleading. The copies of all documents and other
         agreements delivered or furnished and made available by or on behalf of
         Contributor to Acquiror pursuant to this Agreement constitute all of
         and the only Leases and other agreements to which Contributor is
         presently a party relating to or affecting the ownership, leasing,
         management and operation of the Properties, there being no "side" or
         other agreements, written or oral, in force or effect, to which
         Contributor is a party or to which any Property is subject.

                     (xxiv) The OP Units are being acquired by each of the OP
         Unit Recipients with the present intention of holding the OP Units for
         purposes of investment and not with a view towards sale or any other
         distribution. Each of the OP Unit Recipients recognizes that he may be
         required to bear the economic risk of an investment in the OP Units for
         an indefinite period of time. Each OP Unit Recipient is an Accredited
         Investor. Each OP Unit Recipient has such knowledge and experience in
         financial and business matters so as to be fully capable of evaluating
         the merits and risks of an investment in the OP Units. Each OP Unit
         Recipient has received and reviewed the following documents: (A) the
         Form 10-K for the year ended December 31, 1996 for the REIT and
         Acquiror; (B) the annual proxy statement of the REIT for the 1997
         annual meeting and the proxy statement of the REIT for the special
         meeting of stockholders which was held on December 12, 1997; (C) the
         Form 10-Q for the REIT and Acquiror for the quarters ended March 31,
         1997, 



                                       21
<PAGE>


         June 30, 1997, and September 30, 1997, respectively; (D) the Form 8-Ks
         filed by the REIT and Acquiror since December 31, 1996 and (E) the
         Partnership Agreement. Each OP Unit Recipient has been afforded the
         opportunity to ask questions of those persons he considers appropriate
         and to obtain any additional information he desires in respect of the
         OP Units and the business, operations, conditions (financial and
         otherwise) and current prospects of Acquiror and the REIT. Each OP
         Unit Recipient has consulted his own financial, legal and tax advisors
         with respect to the economic, legal and tax consequences of delivery
         of the OP Units and has not relied on Acquiror, the REIT or any of
         their officers, directors, affiliates or professional advisors for
         such advice as to such consequences.

                      (xxv) Except as set forth in Schedule 8A(xxv) attached to
                  this Agreement:

                           (a) The Properties are owned and operated by
                  Contributor in compliance with all Environmental Laws, except
                  for instances of non-compliance as would not individually or
                  in the aggregate reasonably expected to have a Contributor
                  Material Adverse Effect.

                           (b) There have been no past and there are no pending
                  or, to the knowledge of Contributor, threatened (in writing)
                  claims, complaints, notices, correspondence or requests for
                  information received by Contributor with respect to any
                  violation or alleged violation of any Environmental Law or
                  Environmental Permit or with respect to any corrective or
                  remedial action for or cleanup of the Properties or any
                  portion thereof.

                           (c) There have been no Releases of a Hazardous
                  Material at, on, under, in or about any of the Properties or
                  any portion thereof during any period that Contributor owned
                  or leased such Property, or to the best of Contributor's
                  knowledge, prior thereto. None of the Properties is listed, or
                  to the best of Contributor's knowledge, proposed for listing,
                  on the National Priorities List promulgated pursuant to CERCLA
                  (the "NPL") or on any similar state or other list of sites
                  that require or may require corrective or remedial action.

                           (d) To the best of Contributor's knowledge, no
                  conditions exist at, on, under, in or about the Properties or
                  any portion thereof that, with the passage of time or the
                  giving of notice or both, would give rise to any claim,
                  liability or obligation under any Environmental Law or
                  Environmental Permit.

                           (e) Contributor has been issued all Environmental
                  Permits required for the operation of the Properties. All such
                  Environmental Permits are in full force and effect and
                  Contributor is in compliance in all material respects with the
                  terms and conditions of such Environmental Permits.

                           (f) The Properties are not listed, or to the
                  knowledge of Contributor, proposed or nominated for listing on
                  the NPL or on any other similar state or other list of sites
                  that require or may require corrective or remedial action.

                           (g) Contributor has not transported, disposed of or
                  treated, or arranged for the transportation, disposal or
                  treatment of, any Hazardous Material from the Properties or
                  any portion thereof to any location that is: (i) listed, or to
                  the best of Contributor's knowledge, proposed or nominated for
                  listing, on the NPL or on any other similar list or (ii) the
                  subject of any pending, or to the best of Contributor's
                  knowledge, threatened, Federal, state or local enforcement
                  action or other investigation under any Environmental Law.

                           (h) There are no underground storage tanks at, on or
                  under the Properties or any portion thereof. Contributor has
                  not removed, closed or abandoned any underground storage tanks
                  at any of the Properties, and Contributor has no knowledge of
                  the existence, abandonment, closure or removal of underground

                           (i) There have been no environmental investigations,
                  studies, audits, tests, reviews or other analyses conducted
                  by, or which are in the possession of, Contributor in relation
                  to any Property which have not been delivered to Acquiror

                  (4) "Release" means any spill, discharge, leak, migration,
         emission, escape, injection, dumping or other release or threatened
         release of any Hazardous Material into the environment, whether or not
         notification or reporting to any governmental authority was or is
         required. Release includes, without limitation, the meaning of Release
         as defined under CERCLA.

                  B. Contributor represents and warrants to Acquiror that, as of
the Closing, each of the representations and warranties set forth in Section 8A
above shall be true, complete and correct except for changes in the operation of
the Properties occurring prior to the Closing that are specifically permitted by
or pursuant to this Agreement.

                  C. Acquiror represents and warrants to Contributor that the
following are true, complete and correct as of the date of this Agreement:

                        (i) Acquiror is a limited partnership duly formed,
         validly existing and in good standing under the laws of the State of
         Delaware and has all requisite partnership power and authority to own,
         lease and operate its properties and assets as they are now owned,
         leased and operated and to carry on its business as now conducted and
         presently proposed to be conducted. Acquiror is duly qualified,
         licensed or admitted to do business and is in good standing in those
         jurisdictions in which the ownership, use, or leasing of its assets and
         properties, or the conduct or nature of its business makes such
         qualification, licensing or admission necessary, except for failures to
         be so qualified, licensed or admitted and in good standing that
         individually or in the aggregate would not materially adversely affect
         the assets, business, operations or condition (financial or otherwise)
         of Acquiror or the ability of Acquiror to perform its obligations under
         this Agreement (an "Acquiror Material Adverse Effect").

                       (ii) Acquiror has all partnership power and authority to
         enter into, execute and deliver this Agreement and to perform fully its
         obligations hereunder. The execution, delivery and performance by
         Contributor of this Agreement and the other documents to be delivered
         by Acquiror at Closing, and the consummation by Acquiror of the
         transactions contemplated hereby and thereby are permitted under the
         Partnership Agreement, and at Closing will have been duly and validly
         authorized by all necessary partnership action on the part of Acquiror.
         This Agreement has been duly executed and delivered by Acquiror and is
         a valid and binding obligation of Acquiror, enforceable against
         Acquiror in accordance with its terms.

                      (iii) To the best of Acquiror's knowledge, it is not (a)
         in violation of the Partnership Agreement, (b) in default, and no event
         has occurred which, with notice or lapse of time or both, would
         constitute such a default, in the due performance or observance of any
         obligation, agreement, covenant or condition contained in any material
         indenture, mortgage, deed of trust, loan or credit agreement, lease,
         contract or other material agreement or instrument to which it is a
         party or by which it is bound or to which any of its properties or
         assets is subject or by which it, or any of them, may be materially
         affected, or (c) in violation or in conflict with any provision of any
         Laws or Orders applicable to Acquiror or its assets, except in the case
         of clauses (b) and (c) for such defaults, violations or conflicts that
         individually or in the aggregate would not reasonably be expected to
         have an Acquiror Material Adverse Effect.

                       (iv) The Partnership Agreement is in full force and
         effect and has not been further amended or modified.



                                       24
<PAGE>


                        (v) The OP Units to be issued to the OP Unit Recipients,
         when issued, sold and paid for pursuant to this Agreement and the
         Partnership Agreement, will be duly authorized, validly issued, and
         fully-paid.

                       (vi) There is no existing or, to Acquiror's knowledge,
         threatened, legal action or governmental proceedings of any kind
         involving Acquiror, any of its assets or the operation of any of the
         foregoing, which, if determined adversely to Acquiror or its assets,
         would have an Acquiror Material Adverse Effect.

                      (vii) The REIT is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Maryland
         and has all requisite corporate power and authority to own, lease and
         operate its properties and assets as they are now owned, leased and
         operated and to carry on its business as now conducted and presently
         proposed to be conducted. The REIT is duly qualified, licensed or
         admitted to do business and is in good standing in those jurisdictions
         in which the ownership, use, or leasing of its assets and properties,
         or the conduct or nature of its business makes such qualification,
         licensing or admission necessary, except for failures to be so
         qualified, licensed or admitted and in good standing that individually
         or in the aggregate would not materially adversely affect the assets,
         business, operations or condition (financial or otherwise) of the REIT
         (a "REIT Material Adverse Effect"). The REIT is the sole general
         partner of the Acquiror.

                     (viii) The REIT has all requisite corporate power and
         authority to enter into, execute and deliver this Agreement in its
         capacity as general partner of Acquiror and to perform fully its
         obligations hereunder in its capacity as general partner of Acquiror.
         The execution, delivery and performance by the REIT of this Agreement
         and the other documents to be delivered by the REIT at Closing, and the
         consummation by the REIT of the transactions contemplated hereby and
         thereby at Closing will have been duly and validly authorized by all
         necessary corporate action on the part of the REIT. This Agreement has
         been duly executed and delivered by the REIT and is a valid and binding
         obligation of the REIT, enforceable against the REIT in accordance with
         its terms.

                       (ix) To the best of the REIT's knowledge, it is not (a)
         in violation of its Certificate of Incorporation or by-laws, (b) in
         default, and no event has occurred which, with notice or lapse of time
         or both, would constitute such a default, in the due performance or
         observance of any obligation, agreement, covenant or condition
         contained in any material indenture, mortgage, deed of trust, loan or
         credit agreement, lease, contract or other material agreement or
         instrument to which it is a party or by which it is bound or to which
         any of its properties or assets is subject or by which it, or any of
         them, may be materially affected, or (c) in violation or in conflict
         with any provision of any Laws or Orders applicable to the REIT or its
         assets, except in the case of clauses (b) and (c) for such defaults,
         violations or conflicts that individually or in the aggregate would not
         reasonably be expected to have a REIT Material Adverse Effect.

                        (x) The Conversion Shares will be duly authorized and
         reserved for issuance and, to the extent delivered upon exchange of the
         OP Units, when issued, sold and paid for pursuant to this Agreement and
         the Partnership Agreement, will be validly issued, fully-paid and
         nonassessable.

                       (xi) The REIT is organized and operates as a "real estate
         investment trust" under Sections 856 through 860 of the Code. The REIT
         has elected to be taxed as a "real estate 



                                       25
<PAGE>


         investment trust" under the Code.

                      (xii) There is no existing, or, to the REIT's knowledge,
         threatened legal action or governmental proceedings of any kind
         involving the REIT, any of its assets or the operation of any of the
         foregoing, which, if determined adversely to the REIT or its assets,
         would have a material adverse effect on the financial condition,
         business or operations of the REIT or its assets and which would
         interfere with the REIT's ability to perform its obligations under the
         REIT Documents.

                  D. Acquiror represents and warrants to Contributor that, as of
the Closing, each of the representations and warranties set forth in Section 8C
above shall be true, complete and correct.

                  E. Except as hereinafter provided, all representations and
warranties made in this Section 8 by Contributor and/or the OP Unit Recipient
(collectively, the "Contributor Party") and by Acquiror shall survive the
Closing until the second (2nd) anniversary of the Closing Date and shall not
merge into any instrument of conveyance delivered at the Closing; provided,
however, that the foregoing limitation shall not apply to the extent any claim
for indemnification is made under this Agreement with respect to any
representation, warranty, covenant or agreement that would otherwise terminate
pursuant to this Section 8E and a notice for indemnification shall have been
timely given under Section 14 on or prior to such termination date, in which
case such survival period will be extended as it relates to such related claims
until the related claim for indemnification has been satisfied or otherwise
resolved as provided in Section 14. This Section shall not limit in any way the
survival and enforceability of any covenant or agreement of the parties hereto
which by its terms contemplates performance after the Closing Date, which shall
survive for the respective periods set forth herein. Notwithstanding the
foregoing, the representations and warranties contained in Section 8A(xv), (xvi)
and (xxv) shall survive until the expiration of the statute of limitations
applicable thereto.

                  F. Contributor shall provide to Acquiror and its auditors (i)
during the Inspection Period and following the Closing, access at all reasonable
times to all financial and other information relating to the Properties
necessary for Acquiror and its auditors to prepare audited, and if necessary,
pro forma, financial statements in conformity with Regulations S-X of the
Securities and Exchange Commission ("SEC") or other materials required for any
registration statement, report or other disclosure to be filed with the SEC or
necessary to comply with any SEC rule or regulation, and (ii) at the Closing (or
prior thereto if required by Acquiror's auditors) an executed representations
letter, in form and substance reasonably satisfactory to Acquiror, as required
by Generally Accepted Auditing Standards as promulgated by the Auditing
Standards Division of the American Institute of Public Accountants, which
representation is required to enable an independent public accountant to render
an opinion on such financial statements; provided, however, that Acquiror shall
pay for any actual reasonable costs incurred by Contributor in connection with
its obligations under this Section 8F. The obligation of Contributor to provide
such access and representation letter shall survive the Closing and Contributor
shall indemnify and hold Acquiror harmless from and against any losses, costs,
expenses (including, without limitation, reasonable attorneys' fees and
expenses) and liabilities arising from Contributor's failure to comply with
these obligations. This indemnity shall survive the Closing for a period of two
(2) years.

         9.       ACQUIROR'S INSPECTION OF THE PROPERTIES

                  Subject to the provisions of Section 15B, during the period
extending to and including the 45th day from the date of this Agreement (the
"Inspection Period"), Acquiror and Acquiror's agents, engineers, surveyors,
consultants, appraisers, auditors and other representatives (collectively,
"Representatives") will, upon reasonable advance notice, be given the right to
enter upon the Properties and perform nondestructive physical tests and to
conduct any and all necessary engineering, environmental and other surveys,
tests and inspections at the Properties and to examine and evaluate any books
and records, agreements and documents within the possession of Contributor or
subject to its control (whether or not located at the Properties), as Acquiror
or Acquiror's agents may reasonably request. Contributor shall cooperate fully
with the inspections hereunder by Acquiror and its Representatives, and shall
furnish to Acquiror and its Representatives all such books, records, information
(financial or otherwise), data and agreements that Acquiror or Acquiror's
Representatives may reasonably request in connection with the investigations
hereunder, including but not limited to, copies of all leases, Services
Contracts, insurance policies, environmental reports, working drawings, plan and
specifications, surveys, appraisals, engineering and architect reports, real
estate tax bills and receipts, operating statements and related documents.
Acquiror shall have the right to perform a Phase One environmental assessment of
each of the Properties. Upon Acquiror's receipt of any such Phase One
assessment, it shall provide a copy thereof to Contributor (at no cost to
Contributor). If such Phase One assessment should recommend further inspections
and testing at the Properties, Acquiror shall have the option, to be exercised
by written notice given to Contributor prior to the expiration of the Inspection
Period, to extend the Inspection Period for one (1) additional period of thirty
(30) days. Except as otherwise provided herein, Acquiror's obligations under
this Agreement shall be contingent, only during the Inspection Period, upon
Acquiror being satisfied in its sole discretion with the results of its
investigation and evaluation of the Properties (the "Inspection Condition"). In
the event the Inspection Condition is not so satisfied, Acquiror shall notify
Contributor in writing (the "Termination Notice") prior to the expiration of the
Inspection Period that it is terminating this Agreement. If Acquiror shall give
the Termination Notice to Contributor prior to the expiration of the Inspection
Period, the Earnest Money shall be promptly returned to Acquiror and all parties
hereto shall be released from all further obligations and liabilities hereunder,
except with respect to the indemnity set forth in Section 15B. In the event that
Acquiror does not give the Termination Notice to Contributor prior to the
expiration of the Inspection Period, Acquiror shall be deemed to have waived the
Inspection Condition and Acquiror's right to terminate this Agreement pursuant
to this Section 9 shall be deemed deleted from this Agreement.

         10.      SCHEDULES

                  Within three (3) business days after the date of this
Agreement, to the extent not previously delivered, Contributor shall furnish to
Acquiror:

                        (i) a true, correct and complete copy of each written
         Service Contract and a true, correct and complete summary of each oral
         Service Contract;

                       (ii) true, correct and complete copies of all of the 
         Leases;

                      (iii) copies of all operating statements for the
         Properties that are in the possession or control of Contributor for any
         time during the period commencing with the first day of the second full
         calendar year preceding the date of this Agreement and ending on the
         date of this Agreement; and

                       (iv) copies of the most recent survey of and title policy
         or commitment for each 



                                       27
<PAGE>


         of the Properties in the possession or control of Contributor.

         11.      CONDITIONS PRECEDENT

                  A. Acquiror's obligation to acquire the Properties shall be
subject to and contingent upon the following conditions precedent, any or all of
which Acquiror may waive only by a notice delivered in accordance with Section
15H:

                        (i) The issuance to Acquiror at the Closing of the Title
         Policies in accordance with Section 5B(i).

                       (ii) Contributor shall have obtained and delivered to
         Acquiror original executed tenant estoppel certificates (the "Tenant
         Estoppel Certificates") in substantially the form of Exhibit K attached
         hereto, dated not more than thirty (30) days before Closing, and
         executed by tenants under Leases leasing not less than ninety-five
         percent (95%) of the total aggregate gross rental income for all of the
         Properties, including, without limitation, those particular tenants
         listed in Exhibit L attached hereto ("Required Estoppel Tenants").
         Contributor shall use its reasonable, good faith and diligent efforts
         to obtain the Tenant Estoppel Certificates. To the extent that the
         Tenant Estoppel Certificate obtained from a tenant contains less than
         all of the Exhibit K information, or to the extent that, after
         satisfying the above condition, Contributor is unable to obtain Tenant
         Estoppel Certificates from all of the remaining tenants, then, at
         Closing, Contributor shall execute a Tenant Estoppel Certificate with
         respect to those Leases for which no or an insufficient Tenant Estoppel
         Certificate has been obtained (provided that in the case of an
         insufficient Tenant Estoppel Certificate the certification from
         Contributor shall be limited to the insufficient matters). With respect
         to tenants who have signed Leases but not yet taken occupancy, the
         Tenant Estoppel Certificate shall appropriately identify the full and
         complete Lease but will omit certifications that are inappropriate.

                      (iii) The termination, on or before the Closing Date, of
         all of the Service Contracts that Acquiror has elected to terminate by
         written notice given to Contributor prior to the expiration of the
         Inspection Period.

                       (iv) The representations and warranties made by
         Contributor in this Agreement shall be true and correct in all material
         respects on the Closing Date as if made on the Closing Date.

                        (v) The delivery by Contributor of all documents
         (executed by parties other than Acquiror, where required) required
         under Section 6B(i).

                       (vi) The delivery of all necessary consents and approvals
         of lenders under Existing Indebtedness to be assumed by Acquiror, and
         the consents and approvals set forth on Schedule 11A(vi) to this
         Agreement.

                      (vii) Contributor not being otherwise in default of its
         obligations under this Agreement.

                     (viii) All conditions precedent set forth in Section 11A of
         the Northeastern Contribution Agreement shall have been satisfied or,
         if permissible, waived.

                  If the condition precedent set forth in Section 11A(i) is not
         satisfied or waived on or prior 



                                       28
<PAGE>


to the Closing Date, Acquiror shall have the rights and remedies set forth in
Section 5C. If any of the conditions precedent set forth in Section 11A(ii) or
Section 11A(viii) (to the extent a condition under the Northeastern Contribution
Agreement is not satisfied or, if permissible, waived which allows for a similar
termination right without the right to receive costs and expenses) is not
satisfied or waived on or prior to the Closing Date, Acquiror shall have the
right to terminate this Agreement upon written notice to Contributor, and in
which event Escrowee shall immediately return the Earnest Money to Acquiror and
this Agreement, without further action of the parties, shall become null and
void and neither party shall have any further rights or obligations under this
Agreement except with respect to the Surviving Indemnities. If any of the
conditions precedent set forth in Sections 11A(iii), (iv), (v), (vi) or (vii) or
Section 11A(viii) (to the extent a condition under the Northeastern Contribution
Agreement is not satisfied or, if permissible, waived which allows for a similar
termination right with the right to receive costs and expenses) is not satisfied
or waived on or prior to the Closing Date, then Acquiror shall have the rights
and remedies provided in Section 13B.

                  B. Contributor's obligation to contribute and convey the
Properties shall be subject to and contingent upon the following conditions
precedent, any or all of which Contributor may waive by a notice delivered in
accordance with Section 15H:

                        (i) The representations and warranties made by Acquiror
         in this Agreement shall be true and correct in all material respects on
         the Closing Date as if made on the Closing Date.

                       (ii) The delivery by Acquiror of all documents (executed
         by Acquiror, where required) required under Section 6B(ii).

                      (iii) Acquiror not being otherwise in default of its
         obligations under this Agreement.

                       (iv) All conditions precedent set forth in Section 11B of
         the Northeastern Contribution Agreement shall have been satisfied or,
         if permissible, waived.

                  If any of the conditions precedent set forth in Section 11B is
not satisfied or waived on or prior to the Closing Date, then Contributor shall
have the rights and remedies provided in Section 13A.

         12.      BROKERAGE

                  Contributor and Acquiror represent and warrant to each other
that neither they nor their affiliates have dealt with any broker, finder or the
like in connection with the transaction contemplated by this Agreement other
than John Blumberg (the "Broker"). At the Closing, Acquiror shall pay a
commission to the Broker pursuant to a separate agreement between Acquiror and
the Broker; provided, however, that no commission shall be deemed earned unless
and until the Closing shall have occurred as provided in this Agreement and
title to the Properties shall have been conveyed to Acquiror. Acquiror and
Contributor each agrees to indemnify, defend and hold the other harmless from
and against all loss, expense (including reasonable attorneys' fees and court
costs), damage and liability resulting from the claims of any other broker or
finder (or anyone claiming to be a broker or finder) on account of any services
claimed to have been rendered to the indemnifying party in connection with the
transaction contemplated by this Agreement. The provisions of this Section shall
survive the Closing or the sooner termination of this Agreement.



                                       29
<PAGE>


         13.      DEFAULT AND REMEDIES

                  A. If the Closing does not occur due to Acquiror's default
hereunder, or the breach of the representations, warranties, covenants or other
terms of this Agreement, and such default or breach is not cured or remedied
within ten (10) business days after receipt of written notice thereof given by
Contributor to Acquiror, or otherwise waived by Contributor, Contributor may
terminate this Agreement and, as its sole remedy, receive the Earnest Money from
the Escrowee, as liquidated damages, in which event this Agreement shall be
deemed null and void and the parties shall be released from all further
obligations and liabilities under this Agreement, except with respect to the
indemnity set forth in Section 15B. It is recognized by Contributor and Acquiror
that the damages Contributor will sustain by reason of Acquiror's default,
breach or failure will be substantial, but difficult, if not impossible, to
ascertain. The Earnest Money has been determined by the parties as a reasonable
sum for damages and is intended not as a penalty, but as full liquidated
damages.

                  B. If, prior to the Closing, Contributor is in default with
respect to, or breaches, or fails to perform one or more of the representations,
covenants, warranties or other terms of this Agreement, and such default, breach
or failure is not cured or remedied within ten (10) business days after receipt
of written notice thereof given by Acquiror to Contributor, or otherwise waived
by Acquiror, Acquiror as its sole remedy may either (a) terminate this
Agreement, in which event the Earnest Money shall be returned by the Escrowee to
Acquiror and Contributor shall reimburse Acquiror for its reasonable
out-of-pocket expenses incurred by Acquiror (not to exceed $50,000 in the
aggregate) pursuant to this Agreement and, upon such return and reimbursement,
the parties shall be released from all further obligations and liabilities under
this Agreement, except with respect to the Surviving Indemnities, or (b) sue for
specific performance (except in such case where such default, breach or failure
to perform is the result of the good faith failure despite best efforts by
Contributor to obtain the consent of Manufacturers, Traders & Trust Company and
Dorman & Wilson, Inc.). In the event Acquiror elects the remedy set forth in (a)
above, Contributor shall reimburse Acquiror for such expenses within fifteen
(15) days after Contributor's receipt of written notice from Acquiror
accompanied by copies of invoices detailing such expenses or such other
documentation that reasonably substantiates such expenses.

         14.      INDEMNIFICATION

                  A. Indemnification by Contributor. Contributor agrees to
indemnify Acquiror and its respective shareholders, directors, employees,
agents, partners and affiliates in respect of, and hold each of them harmless
from and against, any and all losses, liabilities (including punitive or
exemplary damages, fines or penalties and interest thereon), expenses (including
fees and disbursements of counsel and expenses of investigation and defense),
claims or other obligations of any value whatsoever (collectively, "Losses")
suffered, incurred or sustained by any of them or to which any of them becomes
subject, resulting from, arising out of or relating to (i) any breach of or
inaccuracy in any representation or warranty, or nonfulfillment of or failure to
perform or breach of any covenant or agreement on the part of Contributor
contained in this Agreement, or (ii) any default or dispute set forth in
Schedule 8A(iii) attached to this Agreement.

                  B. Indemnification by Acquiror. Acquiror agrees to indemnify
the Contributor and its shareholders, officers, directors, employees, agents,
partners, members and affiliates in respect of, and hold each of them harmless
from and against, any and all Losses suffered, incurred or sustained by any of
them or to which any of them becomes subject, resulting from, arising out of or
relating to any breach of or inaccuracy in any representation or warranty, or
nonfulfillment of or failure to perform or breach of any 



                                       30
<PAGE>


covenant or agreement on the part of Acquiror contained in this Agreement.

                  C. Method of Asserting Claims. All claims for indemnification
by any Indemnified Party under this Section 14 will be asserted and resolved as
follows:

                        (i) In the event any claim or demand in respect of which
an Indemnified Party might seek indemnity under this Section 14 is asserted
against or sought to be collected from such Indemnified Party by a person or
entity other than Contributor, Acquiror or any Affiliate of the Contributor or
Acquiror (a "Third Party Claim"), the Indemnified Party shall deliver a Claim
Notice (as defined below) with reasonable promptness to the Indemnifying Party.
If the Indemnified Party fails to provide the Claim Notice with reasonable
promptness after the Indemnified Party receives notice of such Third Party
Claim, the Indemnifying Party will not be obligated to indemnify the Indemnified
Party with respect to such Third Party Claim to the extent that the Indemnifying
Party's ability to defend has been irreparably prejudiced by such failure of the
Indemnified Party. The Indemnifying Party will notify the Indemnified Party as
soon as practicable within the Dispute Period (as defined below) whether the
Indemnifying Party disputes its liability to the Indemnified Party under this
Section 14 and whether the Indemnifying Party desires, at its sole cost and
expense, to defend the Indemnified Party against such Third Party Claim.

                        (a) If the Indemnifying Party notifies the Indemnified
         Party within the Dispute Period that the Indemnifying Party desires to
         defend the Indemnified Party with respect to the Third Party Claim
         pursuant to this Section 14C(i), then the Indemnifying Party will have
         the right to defend, with counsel reasonably satisfactory to the
         Indemnified Party, at the sole cost and expense of the Indemnifying
         Party, such Third Party Claim by all appropriate proceedings, which
         proceedings will be vigorously and diligently prosecuted by the
         Indemnifying Party to a final conclusion or will be settled at the
         discretion of the Indemnifying Party (but only with the consent of the
         Indemnified Party in the case of any settlement that provides for any
         relief other than the payment of monetary damages or that provides for
         the payment of monetary damages as to which the Indemnified Party will
         not be indemnified in full pursuant to this Section 14). The
         Indemnifying Party will have full control of such defense and
         proceedings, including any compromise or settlement thereof; provided,
         however, that the Indemnified Party, at the sole cost and expense of
         the Indemnified Party, at any time prior to the Indemnifying Party's
         delivery of the notice referred to in the first sentence of this clause
         (a), may file any motion, answer or other pleadings or take any other
         action that the Indemnified Party reasonably believes to be necessary
         or appropriate to protect its interests; and provided further, that if
         requested by the Indemnifying Party, the Indemnified Party, at the sole
         cost and expense of the Indemnifying Party, will provide reasonable
         cooperation to the Indemnifying Party in contesting any Third Party
         Claim that the Indemnifying Party elects to contest. The Indemnified
         Party may participate in, but not control, any defense or settlement of
         any Third Party Claim controlled by the Indemnifying Party pursuant to
         this clause (a), and except as provided in the preceding sentence, the
         Indemnified Party will bear its own costs and expenses with respect to
         such participation. Notwithstanding the foregoing, the Indemnified
         Party may take over the control of the defense or settlement of a Third
         Party Claim at any time if it irrevocably waives its right to indemnity
         under this Section 14 with respect to such Third Party Claim.

                        (b) If the Indemnifying Party fails to notify the
         Indemnified Party within the Dispute Period that the Indemnifying Party
         desires to defend the Third Party Claim pursuant to Section 14C(i), or
         if the Indemnifying Party gives such notice but fails to prosecute
         vigorously and diligently or settle the Third Party Claim, or if the
         Indemnifying Party fails to give any notice whatsoever within the
         Dispute Period, then the Indemnified Party will have the right to
         defend, at the sole cost and expense of the Indemnifying Party, the
         Third Party Claim by all appropriate 



                                       31
<PAGE>


         proceedings, which proceedings will be prosecuted by the Indemnified
         Party in a reasonable manner and in good faith or will be settled at
         the discretion of the Indemnified Party (with the consent of the
         Indemnifying Party, which consent will not be unreasonably withheld).
         The Indemnified Party will have full control of such defense and
         proceedings, including any compromise or settlement thereof; provided,
         however, that if requested by the Indemnified Party, the Indemnifying
         Party will, at the sole cost and expense of the Indemnifying Party,
         provide reasonable cooperation to the Indemnified Party and its
         counsel in contesting any Third Party Claim which the Indemnified
         Party is contesting. Notwithstanding the foregoing provisions of this
         clause (b), if the Indemnifying Party has notified the Indemnified
         Party within the Dispute Period that the Indemnifying Party disputes
         its liability hereunder to the Indemnified Party with respect to such
         Third Party Claim and if such dispute is resolved in favor of the
         Indemnifying Party in the manner provided in clause (c) below, the
         Indemnifying Party will not be required to bear the costs and expenses
         of the Indemnified Party's defense pursuant to this clause (b) or of
         the Indemnifying Party's participation therein at the Indemnified
         Party's request, and the Indemnified Party will reimburse the
         Indemnifying Party in full for all reasonable costs and expenses
         incurred by the Indemnifying Party in connection with such litigation.
         The Indemnifying Party may participate in, but not control, any
         defense or settlement controlled by the Indemnified Party pursuant to
         this clause (b), and the Indemnifying Party will bear its own costs
         and expenses with respect to such participation.

                        (c) If the Indemnifying Party notifies the Indemnified
         Party that it does not dispute its liability to the Indemnified Party
         with respect to the Third Party Claim under this Section 14 or fails to
         notify the Indemnified Party within the Dispute Period whether the
         Indemnifying Party disputes its liability to the Indemnified Party with
         respect to such Third Party Claim, the Loss in the amount specified in
         the Claim Notice will be conclusively deemed a liability of the
         Indemnifying Party under this Section 14 and the Indemnifying Party
         shall pay the amount of such Loss to the Indemnified Party on demand.
         If the Indemnifying Party has timely disputed its liability with
         respect to such claim, the Indemnifying Party and the Indemnified Party
         will proceed in good faith to negotiate a resolution of such dispute,
         and if not resolved through negotiations within the Resolution Period,
         such dispute shall be resolved by arbitration in accordance with
         paragraph (iii) of this Section 14C.

                       (ii) In the event any Indemnified Party should have a
claim under this Section 14C against any Indemnifying Party that does not
involve a Third Party Claim, the Indemnified Party shall deliver an Indemnity
Notice (as defined below) with reasonable promptness to the Indemnifying Party.
The failure by any Indemnified Party to give the Indemnity Notice shall not
impair such party's rights hereunder except to the extent that an Indemnifying
Party demonstrates that it has been irreparably prejudiced thereby. If the
Indemnifying Party notifies the Indemnified Party that it does not dispute the
claim described in such Indemnity Notice or fails to notify the Indemnified
Party within the Dispute Period whether the Indemnifying Party disputes the
claim described in such Indemnity Notice, the Loss in the amount specified in
the Indemnity Notice will be conclusively deemed a liability of the Indemnifying
Party under this Section 14 and the Indemnifying Party shall pay the amount of
such Loss to the Indemnified Party on demand. If the Indemnifying Party has
timely disputed its liability with respect to such claim, the Indemnifying Party
and the Indemnified Party will proceed in good faith to negotiate a resolution
of such dispute, and if not resolved through negotiations within the Resolution
Period, such dispute shall be resolved by arbitration in accordance with
paragraph (iii) of this Section 14C.

                       (iii) Any dispute submitted to arbitration pursuant to
this Section 14C shall be finally and conclusively determined by the decision of
a board of arbitration consisting of three (3) members (hereinafter sometimes
called the "Board of Arbitration") selected as hereinafter provided. Each of the



                                       32
<PAGE>


Indemnified Party and the Indemnifying Party shall select one (1) member and the
third member shall be selected by mutual agreement of the other members, or if
the other members fail to reach agreement on a third member within twenty (20)
days after their selection, such third member shall thereafter be selected by
the American Arbitration Association upon application made to it for such
purpose by the Indemnified Party. The Board of Arbitration shall meet in New
York City, New York or such other place as a majority of the members of the
Board of Arbitration determines more appropriate, and shall reach and render a
decision in writing (concurred in by a majority of the members of the Board of
Arbitration) with respect to the amount, if any, which the Indemnifying Party is
required to pay to the Indemnified Party in respect of a claim filed by the
Indemnified Party. In connection with rendering its decisions, the Board of
Arbitration shall adopt and follow such rules and procedures as a majority of
the members of the Board of Arbitration deems necessary or appropriate. To the
extent practical, decisions of the Board of Arbitration shall be rendered no
more than thirty (30) calendar days following commencement of proceedings with
respect thereto. The Board of Arbitration shall cause its written decision to be
delivered to the Indemnified Party and the Indemnifying Party. Any decision made
by the Board of Arbitration (either prior to or after the expiration of such
thirty (30) calendar day period) shall be final, binding and conclusive on the
Indemnified Party and the Indemnifying Party and entitled to be enforced to the
fullest extent permitted by law and entered in any court of competent
jurisdiction. Each party to any arbitration shall bear its own expense in
relation thereto, including but not limited to such party's attorneys' fees, if
any, and the expenses and fees of the member of the Board of Arbitration
appointed by such party, provided, however, that the expenses and fees of the
third member of the Board of Arbitration and any other expenses of the Board of
Arbitration not capable of being attributed to any one member shall be borne in
equal parts by the Indemnifying Party and the Indemnified Party.

notice thereof to Acquiror and allow Acquiror a reasonable opportunity to defend
same.

                  C. Neither this Agreement nor any interest hereunder shall be

Unless otherwise specified, notices shall be deemed given when received, but if
delivery is not accepted, on the earlier of the date delivery is refused or the

Either party hereto may change its address for receiving notices, requests,
demands or other communications by notice sent in accordance with the terms of
this Section 15H.

                  I. Contributor acknowledges that (i) the computation of
taxable income of Acquiror is crucial in the determination of the taxable income
of REIT, (ii) REIT needs to be able to prepare accurate estimates of its taxable
income in order to monitor compliance with the requirement that it distribute
95% of its taxable income to its shareholders, and (iii) the depreciation of the
Properties and the required depreciation allocations under Section 704(c) of the
Code will materially impact the computation of Acquiror's and REIT's taxable
income. Accordingly, Contributor agrees that (i) prior to the expiration of the
Inspection Period, Contributor shall provide Acquiror with tax basis
computations and historical tax 



                                       35
<PAGE>


depreciation schedules updated through the Closing Date for each Property; and
(ii) prior to the expiration of the Inspection Period, Contributor shall provide
Acquiror with all data required to perform depreciation allocations (as
contemplated by Section 704(c) of the Code) with respect to each Property and
the OP Unit Recipient. Such data shall include the tax basis allocable to the OP
Unit Recipient for each Property. In addition, Contributor acknowledges that, in
the event repayment of any Assumed Indebtedness triggers discharge of
indebtedness income under the Code (and particularly Section 61(a)(12) thereof),
the Acquiror's Partnership Agreement shall be amended to specially allocate all
such income to Contributor.

                  J. Except as otherwise required by law or the rules of any
applicable securities exchange or national market system, so long as this
Agreement is in effect, Contributor will not, and will not permit any of its
Representatives to, issue or cause the publication of any press release or make
any other public announcement with respect to the transactions contemplated by
this Agreement without the consent of Acquiror, which consent shall not be
unreasonably withheld. Acquiror and Contributor will cooperate with each other
in the development and distribution of all press releases and other public
announcements with respect to this Agreement and the transactions contemplated
hereby, and will furnish the other with drafts of any such releases and
announcements as far in advance as practicable.

                  K. This Agreement may be executed in any number of identical
counterparts, any or all of which may contain the signatures of fewer than all
of the parties but all of which shall be taken together as a single instrument.
Execution copies of this Agreement may also be exchanged by facsimile, and
facsimile signatures shall be treated as originals.

                  L. When the context so requires, the singular number shall
include the plural and the plural the singular, and the use of any gender shall
include all genders.

                  M. This Agreement may not be modified, discharged or changed
in any respect whatsoever, except by a further agreement in writing duly
executed by Contributor and Acquiror. However, any consent, waiver, approval or
authorization shall be effective if signed by the party granting or making such
consent, waiver, approval or authorization.

                  N. The invalidation or unenforceability in any particular
circumstance of any of the provisions of this Agreement shall in no way affect
any of the other provisions hereof, which shall remain in full force and effect.

                  O. The Properties being acquired by Acquiror pursuant to this
Agreement shall be transferred and conveyed on an "AS-IS" and "WHERE-IS" basis,
and WITH ALL FAULTS, except as otherwise expressly set forth in this Agreement
or in any document delivered by Contributor at Closing. Except as expressly set
forth in this Agreement or in any document delivered by Contributor at Closing,
Contributor has not made any representation or warranty as to the present or
future physical condition, value, presence/absence of hazardous or toxic
materials, financing status, leasing, operations, use, tax status, income and
expense or any other matter pertaining to the Properties.

Section 1(a) herein being collectively called the "Real Property").

      (b) All fixtures, attached or appurtenant to the Real Property; and all 
intangible personal property used in the ownership, operation or maintenance 
of the Real Property, which is not owned by the Tenants; including, without 
limitation, the items set forth on Exhibit B hereto (all of the foregoing 
items of property being herein collectively called the "Personal Property"). 
Certain Tenant leasehold improvements are owned by the respective Tenants, to 
the extent set forth in attachments to the Leases.

      (c) Property. The Urbana Land and the buildings and improvements 
thereon are sometimes herein called the "Urbana Real Property". The 
Marysville Land and the buildings and improvements thereon are sometimes

2. Purchase Price.

      (a) The purchase price (the "Purchase Price") for the Property, subject 
to adjustments and allocation as provided in this Agreement, shall be Twelve 
Million Dollars ($12,000,000), and shall be paid as follows:

         (i) One Hundred Thousand Dollars ($100,000) (such sum, plus all 
interest which accrues thereon, being herein called "the Deposit") shall be 
paid by Buyer to First American Title Insurance Company ("Title Company") on 
or prior to the third business day to occur after the date on which the 
Inspection Period (as defined below) ends. The Deposit shall be held by the 
Title Company in one or more federally-insured money market accounts 
acceptable to both Seller and Buyer, or in short-term United States 
Government obligations having a maturity date which is not later than the 
Closing Date (as defined below).

         (ii) The balance of the Purchase Price shall be paid at Closing by 
wire transfer of immediately available funds.

<PAGE>

Zanesville Real Property as follows (each of the following amounts is herein
called an "Allocation Amount"):

<TABLE>

                   <S>                       <C>
                   Urbana Property     -     $4,100,000
                   Marysville Property -     $2,800,000
                   Zanesville Property -     $5,100,000

</TABLE>

3. Disposition of Deposit; Defaults.

      (a) The Deposit shall be held in escrow and disbursed by the Title 
Company in accordance with the terms of this Agreement. Seller and Buyer each 
agrees, upon request, to execute the Title Company's customary form of escrow 
agreement with respect to the Deposit.

      (b) If Buyer, without the right to do so and in default of its 
obligations under this Agreement fails to complete Closing, Seller shall have 
the right to be paid the Deposit as liquidated damages and not as a penalty. 
Buyer and Seller acknowledge that the damages which may be incurred by Seller 
in the event of Buyer's default are difficult to quantify as of the date of 
this Agreement; the Deposit represents the parties' reasonable estimate of 
Seller's probable future damages in the event of Buyer's default; and that 
the Deposit represents fair and reasonable compensation to Seller in the 
event of Buyer's default. The right of Seller to be paid the Deposit shall be 
Seller's exclusive and sole remedy, and Seller waives any right to recover 
the balance of the Purchase Price, or any part thereof, and the right to 
pursue any other remedy permitted by law or in equity against Buyer.

      (c) If Seller, without the right to do so and in default of its 
obligations under this Agreement fails to complete Closing or otherwise 
defaults under or breaches this Agreement, Buyer shall have the right to be 
paid the Deposit, which right shall be in addition to all other rights and 
remedies of Buyer under this Agreement, at law or in equity, including 
without limitation the right to specific performance and injunctive relief.

      (d) If Closing is completed hereunder, the Title Company shall pay the 
Deposit to Seller on account of the Purchase Price.

      (e) Notwithstanding anything contained in this Section 3, if either 
party terminates this Agreement as a result of the other's default or 
pursuant to the exercise of any right of termination conferred by this 
Agreement, the Title Company shall not disburse the Deposit until the earlier 
to occur of: 


                                      -3-
<PAGE>

(i) receipt by the Title Company of written instructions from Seller and Buyer
or (ii) entry of a final adjudication determining which party is entitled to
receive the Deposit, as applicable, at which time the Deposit shall be
distributed in accordance with such written instructions or adjudication. In the
event of a dispute between the parties with respect to the Deposit, the Title
Company may deposit the Deposit with a court of proper jurisdiction and commence
an interpleader action. Upon notifying Seller and Buyer of the commencement of
such action, the Title Company shall be released of all liability with respect
to the Deposit, except to the extent of accounting for any monies previously
delivered by the Title Company out of escrow. The Title Company shall not be
liable to either Seller or Buyer other than for the performance of its duties
under this Agreement, its gross negligence or intentional wrongdoing.

4. Closing. The closing of this transaction ("Closing") shall take place at the
offices of Wolf, Block, Schorr and Solis-Cohen, Twelfth Floor Packard Building,
15th and Chestnut Streets, Philadelphia, Pennsylvania 19102. Closing shall
commence at 10:00 a.m. on Friday, May 29, 1998 (the "Closing Date"). This
transaction shall close in escrow, pursuant to the terms of the Exchange
Agreement attached hereto as Exhibit C.

5. Condition of Title.

      (a) (i) Title to the Property shall be good and marketable and free and 
clear of all liens, restrictions, easements, encumbrances, leases, tenancies 
and other title objections, except for the Permitted Encumbrances (as defined 
below), and shall be insurable as such and as provided in this Agreement at 
ordinary rates by the Title Company pursuant to an ALTA Owner's Policy of 
Title Insurance, 1970 Form B, amended October 17, 1970 and October 17, 1984 
(the "Owner's Policy of Title Insurance").

         (ii) The Owner's Policy of Title Insurance shall also contain 
endorsements insuring that the covenants, conditions and restrictions 
included in the Permitted Encumbrances have not been violated and that a 
future violation thereof will not cause a forfeiture or reversion of title.

         (iii) The premium (at ordinary rates) for the Owner's Policy of 
Title Insurance and such endorsements will be paid by Buyer.

      (b) If Seller is unable to convey title to the Urbana Property, the 
Marysville Property, and/or the Zanesville Property to Buyer at Closing in 
accordance with the requirements 


                                      -4-
<PAGE>

of this Agreement, Buyer shall have the options: (i) of taking such title to the
defective Property or defective Properties as Seller is able to convey with
abatement of the Purchase Price in the amount (fixed or ascertainable) of any
mortgages or other monetary liens on such defective Property or defective
Properties; or (ii) of terminating Buyer's obligations under this Agreement and
being repaid the Deposit; or (iii) of terminating Buyer's obligations under this
Agreement with respect only to any defective Property, and having this Agreement
continue in effect as to the Property or Properties with respect to which Buyer
did not terminate with a reduction of the Purchase Price in the amount of the
Allocated Amount for the defective Property (or defective Properties) as to
which Buyer has terminated. Upon payment to Buyer of the Deposit pursuant to
clause (ii) above, this Agreement shall be null and void and neither party shall
have any further obligations hereunder. If Buyer terminates this Agreement
pursuant to clause (ii) above, Seller and Buyer shall immediately deliver to the
Title Company written instructions to pay the Deposit to Buyer. Notwithstanding
the foregoing, if title to the Property is not as described in Section 5(a),
Buyer shall also be entitled to pursue all other remedies available to Buyer at
law or in equity.

      (c) Promptly after the execution of this Agreement, Buyer shall order 
from the Title Company a Commitment for Title Insurance ("Title Commitment") 
with respect to the Real Property. Buyer shall give to Seller Notice 
("Exception Notice") of any exceptions to title set forth in the Title 
Commitment which are not acceptable to Buyer ("Unacceptable Exceptions"). 
Seller shall, within five (5) days from the date of Seller's receipt of the 
Exception Notice, deliver to Buyer an endorsement to the Title Commitment 
issued by the Title Company stating which, if any, of the Unacceptable 
Exceptions the Title Company has or will commit to remove from the Title 
Commitment; and if the Title Company has not issued an endorsement to the 
Title Commitment removing (or committing to remove) all of the Unacceptable 
Exceptions from the Title Commitment within five (5) days from the date of 
Seller's receipt of the Exception Notice, Buyer shall have the right to 
terminate this Agreement. If Buyer does not terminate this Agreement pursuant 
to the provisions of this Section 5(c), then the exceptions remaining on 
Schedule B, Section 2 of the Title Commitment which are not liens securing 
payment of monetary sums ("Monetary Liens") shall be the "Permitted 
Encumbrances". Seller agrees to pay all Monetary Liens and cause all Monetary 
Liens to be released and satisfied of record prior to the completion of 
Closing.

6. Possession. Possession of the Property shall be given to Buyer at Closing,
subject only to the right of occupancy of 



                                      -5-
<PAGE>

the Tenants under the Tenant Leases, by delivery of Seller's Special Warranty
Deeds with covenants against the Grantor's acts (the "Deeds") and Bills of Sale
(the "Bills of Sale"), duly executed and acknowledged by Seller and in proper
form for recording, pursuant to the Exchange Agreement attached hereto as
Exhibit C. If Buyer causes surveys to be made of the Real Property, then at
Buyer's option, the descriptions of the Real Property contained in the Deeds
shall be based upon the surveys.

7. Apportionments; Transfer Taxes

      (a) (i) Real estate taxes (on the basis of the actual fiscal years for 
which such taxes are assessed) on the Real Property; personal property taxes 
on the Personal Property; minimum water and sewer charges; minimum rent and 
additional rent and other sums paid by the Tenants to the Seller prior to 
Closing under the Tenant Leases; and payments due under the Service 
Agreements (as defined below) which are to be assigned to Buyer, if any, 
shall be apportioned pro rata between Seller and Buyer on a per diem basis as 
of the Closing Date; provided, however, that there shall be no apportionment 
between Buyer and Seller at Closing with respect to real estate taxes, 
utility charges and other sums paid by the Tenants to the taxing authorities, 
utility companies or other third parties pursuant to the Tenant Leases for a 
period or periods of time from and after the Closing Date.

         (ii) If the Closing Date is not the first day of a calendar month 
and if as of the Closing Date any of the Tenants has not paid the monthly 
installment of minimum rent ("Delinquent Installment") due under its Tenant 
Lease with respect to the month in which Closing occurs, then at Closing 
Buyer shall receive a credit against the Purchase Price in an amount equal to 
the portion of the Delinquent Installment applicable to the period of time 
from and after the Closing Date and through the balance of the applicable 
month; and upon Buyer's receipt of the Delinquent Installment from the 
Tenant, Buyer shall pay the full amount thereof to Seller.

         (iii) If, at Closing, the Property is affected by an assessment 
which is payable in installments of which the first installment is then a 
charge or lien, or has been paid, then all unpaid installments of such 
assessments, including those which are to become due and payable after 
Closing, shall be deemed to be due and payable and to be a lien upon the 
Property and shall be paid and discharged by Seller at Closing.

      (b) Seller and Buyer shall, at Closing, split equally all transfer 
taxes, documentary taxes and all other 


                                      -6-
<PAGE>

taxes, assessments or charges imposed upon the Deeds and/or the conveyance of
the Real Property from Seller to Buyer.

      (c) The total sum of all Tenant security, utility, key and other 
deposits, together with all interest earned thereon as of the Closing Date 
which the Tenants are entitled to receive, shall be given to Buyer at Closing 
as a credit against the Purchase Price.

      (d) Seller shall obtain readings of the water, electric, gas and other 
utility meters servicing the Real Property (other than meters which 
exclusively measure utility consumption which is to be paid in full by any of 
the Tenants under Tenant Leases) to a date no more than five (5) days prior 
to the Closing Date. At or prior to Closing, Seller shall pay all charges 
based upon such meter readings, adjusted to include a reasonable estimate of 
the additional charges due for the period from the dates of the respective 
readings until the Closing Date. If Seller is unable to obtain readings of 
any meters prior to the Closing Date, Closing shall be completed without such 
readings and upon the obtaining thereof, Seller shall pay the charges 
incurred prior to the Closing Date as reasonably determined by Buyer based 
upon such readings, and at Closing, Seller shall deposit with the Title 
Company an amount reasonably estimated to represent the anticipated 
obligation of Seller under this sentence.

8. Representations and Warranties of Seller. Seller, to induce Buyer to enter
into this Agreement and to complete Closing, makes the following representations
and warranties to Buyer, which representations and warranties are true and
correct as of the date of this Agreement, and shall be true and correct at and
as of the Closing Date in all respects as though such representations and
warranties were made both at and as of the date of this Agreement, and at and as
of the Closing Date:

      (a) The only leases or other agreement with respect to rights of use 
and occupancy of the Property in effect are the leases ("Tenant Leases") 
listed on Schedule 1 hereto ("Rent Roll") with the tenants ("Tenants") 
designated on Schedule 1 hereto. The Tenant Lease originally entered into 
between Seller, as landlord, and Dow Brands, as tenant, as been assigned by 
Dow Brands to S.C. Johnson & Son, Inc. and Seller, as landlord, as executed 
an Agreement consenting to such assignment and S.C. Johnson & Son, Inc. has 
executed an Agreement assuming the obligations of the tenant under such 
Tenant Lease.

      (b) The Tenant Leases are valid and existing and in full force and 
effect; the Tenants are in actual possession of 


                                      -7-
<PAGE>

the Property; and neither the Tenants nor the Seller are in default of their
respective obligations under the Tenant Leases.

      (c) The copies of the Tenant Leases previously delivered by Seller to 
Buyer and initialed by Seller and Buyer for identification are true and 
complete copies of the Tenant Leases; the Tenant Leases have not been 
amended, modified, or supplemented; and the Tenants do not have any right to 
extend or renew the terms of the Tenant Leases except as expressly set forth 
in the Tenant Leases.

      (d) The Tenants have not asserted any claims which could adversely 
affect the right of the landlord to collect rent from the Tenants; and no

14(c) with respect to all of the Property, Seller and Buyer shall forthwith

not affect its interpretation.

      (b) Entire Agreement; Governing Law. This Agreement contains the entire 
understanding of the parties with respect to the subject matter hereof, 
supersedes all prior or other negotiations, representations, understandings 
and agreements (including, without limitation, the letter of intent between 
Seller and Buyer dated February 27, 1998) of, by or among the parties, 
express or implied, oral or written, which are fully merged herein. The 
express terms of this Agreement control and supersede any course of 
performance and/or customary practice inconsistent with any such terms. Any 
agreement hereafter made shall be ineffective to change, modify, discharge or 
effect an abandonment of this Agreement unless such agreement is in writing 
and signed by the party against whom enforcement of such change, 
modification, discharge or abandonment is sought. This Agreement shall be 
governed by and construed under the laws of the State of Ohio.

      (c) Provisions Separable. The provisions of this Agreement are 
independent of and separable from each other, and no provision shall be 
affected or rendered invalid or


                                      -26-
<PAGE>

unenforceable by virtue of the fact that for any reason any other provision may
be invalid or unenforceable in whole or in part.

      (d) Waiver of Tender of Deed and Purchase Monies. The tender of an 
executed Deed by Seller and the tender by Buyer of the Purchase Price are 
mutually waived, but nothing in this Agreement shall be construed as a waiver 
of Seller's obligation to deliver the Deed and/or of the concurrent 
obligation of Buyer to pay the portion of the Purchase Price payable at 
Closing.

      (e) Gender, etc. Words used in this Agreement, regardless of the number 
and gender specifically used, shall be deemed and construed to include any 
other number, singular or plural, and any other gender, masculine, feminine 
or neuter, as the context indicates is appropriate.

      (f) Counterparts. This Agreement may be executed in any number of 
counterparts, each of which shall be deemed to be an original as against any 
party whose signature appears thereon, and all of which shall together 
constitute one and the same instrument. This Agreement shall be binding when 
one or more counterparts hereof, individually or taken together, shall bear 
the signatures of all of the parties reflected on this Agreement as the 
signatories.

      (g) Exhibits. All exhibits attached to this Agreement are incorporated 
by reference into and made a part of this Agreement.

      (h) No Waiver. Neither the failure nor any delay on the part of either 
party to this Agreement to exercise any right, remedy, power or privilege 
under this Agreement shall operate as a waiver thereof, nor shall any single 
or partial exercise of any right, remedy, power or privilege preclude any 
other or further exercise of the same or of any other right, remedy, power or 
privilege, nor shall any waiver of any right, remedy, power or privilege with 
respect to any occurrence be construed as a waiver of any such right, remedy, 
power or privilege with respect to any other occurrence. No waiver shall be 
effective unless it is in writing and is signed by the party asserted to have 
granted such waiver.

         (i) Interpretation. No provision of this Agreement is to be 
interpreted for or against either party because that party or that party's 
legal representative or counsel drafted such provision.

      (j) Time. In computing the number of days for purposes of this 
Agreement, all days shall be counted, including 


                                      -27-
<PAGE>

Saturdays, Sundays and holidays; provided, however, that if the final day of any
time period provided in this Agreement shall end on a Saturday, Sunday or legal
holiday, then the final day shall extend to 5:00 p.m. of the next full business
day. For the purposes of this Section, the term "holiday" shall mean a day other
than a Saturday or Sunday on which banks in the State of Ohio are or may elect
to be closed.

      (k) Attorney's Fees. In connection with any litigation arising out of 
this Agreement, the prevailing party shall be entitled to recover all costs 
incurred, including reasonable attorney's fees. However, the provisions of 
this Section are expressly subject to the limitation on Buyer's liability 
specified in Section 3.

      (l) Buyer's Exercise of Right to Terminate. If Buyer desires to 
terminate its obligations under this Agreement pursuant to any of the 
provisions of this Agreement, Buyer shall do so by delivering written notice 
of termination to Seller. Upon any such termination with respect to the 
entire Property, the Deposit shall be paid to Buyer, and except as otherwise 
expressly provided herein, this Agreement shall be and become null and void 
and neither party shall have any further rights or obligations under this 
Agreement. Upon any such termination which does not apply to the entire 
Property, except as otherwise expressly provided herein, this Agreement shall 
be and become null and void with respect to the Property which Buyer 
terminated and neither party shall have any further rights or obligations 
under this Agreement with respect to such Property.

      (m) Survival. The representations, warranties and agreements of Seller 
set forth in Sections 8 and 9 of this Agreement shall survive a termination 
of this Agreement, or Closing for a period of 24 months, and thereafter shall 
survive to the extent that Buyer shall have given to Seller written notice of 
breach thereof. The obligations of Seller and Buyer pursuant to Sections 7, 
10, 16, 17, 20, 21, 22(k), 22(n), 23 and 24 of this Agreement shall survive 
Closing. Except as otherwise provided in the preceding two sentences of this 
Section 22(m), the agreements of Seller and Buyer set forth in this Agreement 
shall not survive Closing and shall merge into the delivery of the Deed at 
Closing.

      (n) Further Assurances. After Closing, each party shall execute, 
acknowledge and deliver, for no further consideration but at the cost of the 
requesting party, all documents and instruments as the other party may 
reasonably request to further evidence or effectuate the purposes of this 
Agreement.

23. Tax Free Exchange. Each of Seller and Buyer shall cooperate with the 
other in effecting an exchange described in Section 1031 of the Internal 
Revenue Code ("Tax Free Exchange"), provided, that: (a) the Tax Free Exchange 
shall not impose additional financial or legal obligations in addition to 
those set forth elsewhere in this Agreement; (b) neither Seller nor Buyer 
shall have any obligation to take title to any exchange property; (c) the 
exchanging party shall indemnify, defend and save and hold the other party 
harmless of an from all expenses, liabilities, claims, losses or actions as a 
result of participation in the Tax Free Exchange; and (d) the other party 
shall have no obligation to modify any of the provisions of this Agreement to 
effect the Tax Free Exchange. Buyer and Seller agree that Seller may 
substitute an intermediary ("Intermediary") to act in place of Seller as the 
seller of the Real Property. Intermediary shall be designated in writing by 
Seller. Upon designation of Intermediary and upon Intermediary's written 
assumption of Seller's obligations, Intermediary shall be substituted for 
Seller for the sale of the Real Property; provided, however, that Seller 
shall remain personally liable for all of the obligations of Seller pursuant 
to this Agreement. Subject to Seller remaining personally liable, Buyer 
agrees to accept the Real Property and all other required performance and any 
escrow instructions from Intermediary and to render its performance of all of 
its obligations to Intermediary. Buyer agrees that performance by 
Intermediary will be treated as performance by Seller, and Seller agrees that 
Buyer's performance to Intermediary will be treated as performance to Seller.

24. Reports. For the period of time commencing on the date of this Agreement 
and continuing through the first anniversary of the Closing Date, and without 
limitation of the other document production otherwise required of Seller 
hereunder, Seller shall, from time to time, upon reasonable advance written 
notice from Buyer, provide to Buyer and its representatives: (i) access to 
all financial and other information pertaining to the period of Seller's 
ownership and operation of the Property, which information is relevant and 
reasonably necessary, in the opinion of Buyer's outside, third party 
accountants ("Accountants") to enable Buyer and its Accountants to prepare 
financial statements in compliance with any and all of (a) Rule 3-05 or Rule 
3-14 of Regulation S-X of the Securities and Exchange Commission (the 
"Commission"), as applicable to Buyer; (b) any other rule issued by the 
Commission and applicable to Buyer; and (c) any registration statement, 
report or disclosure statement filed with the Commission by, or on behalf of 
Buyer; and (ii) a representation letter, in form specified by, or otherwise 
satisfactory to the Accountants, signed by the individual(s) responsible for

Division of the American Institute of Certified Public Accountants, which 
representation letter may be required by the Accountants in order to render 
an opinion concerning Seller's financial statements.

         Any payment of Gross Cash Receipts received from a tenant of a
Mortgaged Property which is delinquent shall be applied to the oldest
outstanding delinquencies relating to such tenant.

         If the Borrower, REA or a Guarantor shall receive cash by reason of
Insurance Proceeds, proceeds of rental loss or business interruption insurance

otherwise would have been due to the Borrower or a Guarantor from tenants of a
Mortgaged Property), title insurance, the forfeiting by tenants of security or
other deposits (except the forfeiting by tenants of security or other deposits
to pay rent), Condemnation Proceeds, Capital Event Proceeds, or any other items
of income which are extraordinary or of a non-recurring nature, such amounts
shall not be included in Gross Cash Receipts. Gross Cash Receipts for any
Determination Period shall include that portion of any payments made by tenants
prior to or during such Determination Period to cancel their Leases which is
equal to the rent that would have otherwise been payable during such
Determination Period under such Leases, provided that if the space vacated by
any such tenant is subsequently re-let for all or any portion of a Determination
Period, any rent paid by the new tenant during such period shall be deemed
included in Gross Cash Receipts for such Determination Period and a
corresponding portion of any lease cancellation payment attributable to such
period shall not be included in Gross Cash Receipts for such period. Gross Cash
Receipts shall not include any amounts payable by tenants holding over pursuant
to expired or terminated Leases. With respect to tenants which are occupying a
Mortgaged Property pursuant to a month-to-month Lease, Gross Cash Receipts from
such Leases shall not exceed five percent (5%) of the aggregate Gross Cash
Receipts in any Determination Period. In addition, Gross Cash Receipts for any
Determination Period shall be reduced by such amount as may be required by the
Agent as a result of negative factors affecting the occupancy of a Mortgaged
Property during such Determination Period and/or the fiscal quarter immediately
following such period as determined by the Agent in its good faith business
judgment, such as defaults by tenants under Leases, potential set-off against
rent, landlord concessions which become effective following a Determination
Period or anticipated or actual lease terminations or expirations. For example
(but without limiting the generality of the foregoing), in the event that a
Lease is scheduled to terminate in the fiscal quarter immediately following a
Determination Period, the Agent may exclude all Gross Cash Receipts received
pursuant to such Lease for such Determination Period. Any such reduction in
Gross Cash Receipts as a result of terminated or expired Leases, or Leases which
are due to terminate or expire, shall be offset by such amount as may be
approved by the Agent in its good faith business judgment as a result of
executed Leases for the premises covered by the terminated or expired Lease.


                                       9

Percentage. Each request for a Loan hereunder shall constitute a representation

or portion thereof commencing on the date hereof and ending on the Maturity

Total Commitment be reduced in such manner to an amount less than $75,000,000)
or to terminate entirely the unborrowed portion of the Commitments, whereupon
the Commitments of the Banks shall be reduced pro rata in accordance with their
respective Commitment Percentages of the amount specified in such notice or, as
the case may be, terminated, any such termination or reduction to be without
penalty except as otherwise set forth in Section 4.8; provided, however, that no
such termination or reduction shall be permitted if, after giving effect
thereto, the Outstanding Loans would exceed the Commitments of the Lenders as so
terminated or reduced. Promptly after receiving any notice from the Borrower
delivered pursuant to this Section 2.3, the Agent will notify the Lenders of the
substance thereof. Upon the effective date of any such reduction or termination,
the Borrower shall pay to the Agent for the respective accounts of the Lenders
the full amount of any facility fee under Section 2.2 then accrued on the amount
of the reduction. No reduction or termination of the Commitment may be
reinstated.

         Section 2.4 Notes. The Loans shall be evidenced by separate promissory
notes of the Borrower in substantially the form of Exhibit F hereto
(collectively, the "Notes"), dated the Closing Date (except as otherwise
provided in Section 18.3) and completed with appropriate insertions. One Note
shall be payable to the order of each Lender in the principal amount equal to
such Lender's Commitment or, if less, the outstanding amount of all Loans made
by such Lender, plus interest accrued thereon, as set forth below. The Borrower
irrevocably authorizes each Lender to


                                       20
<PAGE>

make or cause to be made, at or about the time of the Drawdown Date of any Loan
or the time of receipt of any payment of principal thereof, an appropriate
notation on such Lender's Record reflecting the making of such Loan or (as the
case may be) the receipt of such payment. The outstanding amount of the Loans
set forth on such Lender's Record shall be prima facie evidence of the principal
amount thereof owing and unpaid to such Lender, but the failure to record, or
any error in so recording, any such amount on such Lender's Record shall not
limit or otherwise affect the obligations of the Borrower hereunder or under any
Note to make payments of principal of or interest on any Note when due.

         Section 2.5 Interest on Loans. (a) Each Base Rate Loan shall bear
interest for the period commencing with the Drawdown Date thereof and ending on
the date on which such Base Rate Loan is repaid or converted to a Eurodollar
Rate Loan at the rate per annum equal to the Base Rate.

         (b) Each Eurodollar Loan shall bear interest for the period commencing
with the Drawdown Date thereof and ending on the last day of each Interest
Period with respect thereto at the rate per annum equal to the sum of the
Eurodollar Rate determined for such Interest Period plus one and six hundred
twenty five thousandths percent (1.625%).

         (c) The Borrower promises to pay interest on each Loan in arrears (i)
on each Interest Payment Date with respect thereto, (ii) upon any prepayment of
the Loans (to the extent accrued on the amount being prepaid to the date of
prepayment) and (iii) at maturity of the Loans.

         (d) Base Rate Loans and Eurodollar Loans may be converted to Loans of
the other Type as provided in Section 4.1.

         Section 2.6 Requests for Loans. The Borrower shall give to the Agent
written notice in the form of Exhibit G hereto (or telephonic notice confirmed
in writing in the form of Exhibit G hereto) of each Loan requested hereunder (a
"Loan Request") no less than one (1) Business Day prior to the proposed Drawdown
Date with respect to Base Rate Loans and three (3) Business Days prior to the
proposed Drawdown Date with respect to Eurodollar Rate Loans. Each such notice
shall specify with respect to the requested Loan the proposed principal amount
of such Loan, the Type of Loan, the initial Interest Period (if applicable) for
such Loan and the Drawdown Date. Each such notice shall also contain (i) a
general statement as to the purpose for which such advance shall be used (which
purpose shall be in accordance with the terms of Section 2.8), (ii) a
certification by the chief financial officer or chief accounting officer of the
Borrower that the Borrower, REA and the Guarantors are and will be in compliance
with all covenants under the Loan Documents after giving effect to the making of
such Loan, and (iii) a Compliance Certificate prepared using the financial
statements of REA most recently provided or required to be provided to the Agent
under Section 6.4 or Section 7.4 adjusted in the best good faith estimate of the
Borrower to give effect to the proposed advance. Promptly upon receipt of any
such notice, the Agent shall notify each of the Lenders thereof. Except as
provided in this Section 2.6, each such Loan Request shall be irrevocable and
binding on the Borrower and shall obligate the Borrower to accept the Loan
requested from the Lenders on the proposed Drawdown Date; provided that, in
addition to the Borrower's other remedies against any Lender which fails to
advance its proportionate share of a requested Loan, such Loan Request may be
revoked by the Borrower by


                                       21
<PAGE>

notice received by the Agent no later than the Drawdown Date if any Lender fails
to advance its proportionate share of the requested Loan in accordance with the
terms of this Agreement; and provided further that the Borrower shall be liable
in accordance with the terms of this Agreement to any Lender which is prepared
to advance its proportionate share of the requested Loan for any costs, expenses
or damages actually incurred by such Lender as a result of the Borrower's
election to revoke such Loan Request. Nothing herein shall prevent the Borrower
from seeking recourse against any Lender that fails to advance its proportionate
share of a requested Loan as required by this Agreement. Each Loan Request shall
be (a) for a Base Rate Loan in a minimum aggregate amount of $1,000,000 or an
integral multiple of $100,000 in excess thereof; or (b) for a Eurodollar Rate
Loan in a minimum aggregate amount of $2,000,000 or an integral multiple of
$100,000 in excess thereof; provided, however, that there shall be no more than
eight (8) Eurodollar Rate Loans outstanding at any one time.

         Section 2.7 Funds for Loans. (a) Not later than 11:00 a.m. (Boston
time) on the proposed Drawdown Date of any Loans, each of the Lenders will make
available to the Agent, at the Agent's Head Office, in immediately available
funds, the amount of such Lender's Commitment Percentage of the amount of the
requested Loans which may be disbursed pursuant to Section 2.1. Upon receipt
from each Lender of such amount, and upon receipt of the documents required by
Section 10 and Section 11 and the satisfaction of the other conditions set forth
therein, to the extent applicable, the Agent will make available to the Borrower
the aggregate amount of such Loans made available to the Agent by the Lenders by
crediting such amount to the account of the Borrower maintained at the Agent's
Head Office. The failure or refusal of any Lender to make available to the Agent
at the aforesaid time and place on any Drawdown Date the amount of its
Commitment Percentage of the requested Loans shall not relieve any other Lender
from its several obligation hereunder to make available to the Agent the amount
of such other Lender's Commitment Percentage of any requested Loans, including
any additional Loans that may be requested subject to the terms and conditions
hereof to provide funds to replace those not advanced by the Lender so failing
or refusing. In the event of any such failure or refusal, the Lenders not so
failing or refusing shall be entitled to a priority secured position as against
the Lender or Lenders so failing or refusing to make available to the Borrower
the amount of its or their Commitment Percentage for such Loans as provided in
Section 12.4.

         (b) Unless the Agent shall have been notified by any Lender prior to
the applicable Drawdown Date that such Lender will not make available to Agent
such Lender's pro rata share of a proposed Loan, the Agent may in its discretion
assume that such Lender has made such Loan available to Agent in accordance with
the provisions of this Agreement and the Agent may, if it chooses, in reliance
upon such assumption make such Loan available to the Borrower, and such Lender
shall be liable to the Agent for the amount of such advance.

         Section 2.8 Use of Proceeds. The Borrower will use the proceeds of the
Loans solely to provide financing (a) for the acquisition by the Borrower
pursuant to the terms thereof fee interests or leasehold interests in Real
Estate which (except as otherwise agreed by the Majority Lenders as referred to
in clause (c) of the definition of Eligible Real Estate) is utilized for office
and/or industrial purposes, (b) for Capital Improvement Projects for Real
Estate; (c) for working capital purposes (provided that the aggregate amount of
Loans outstanding for working capital


                                       22
<PAGE>

purposes shall not at any one time exceed $25,000,000), and (d) for such other
purposes as the Majority Lenders in their sole discretion from time to time may
agree in writing.

         Section 3 REPAYMENT OF THE LOANS.

         Section 3.1 Stated Maturity. The Borrower promises to pay on the
Maturity Date and there shall become absolutely due and payable on the Maturity
Date all of the Loans outstanding on such date, together with any and all
accrued and unpaid interest thereon.

         Section 3.2 Mandatory Prepayments. If at any time the aggregate
outstanding principal amount of the Loans exceeds the aggregate Commitments or
the Borrowing Base for the Loans, then the Borrower shall immediately pay the
amount of such excess to the Agent for the respective accounts of the Lenders
for application to such Loans. In the event there shall have occurred a casualty
with respect to any Mortgaged Property and the Borrower is required to repay the
Loans pursuant to Section 7.7 or a Taking and the Borrower is required to repay
the Loans pursuant to a Mortgage, the Borrower shall prepay the Loans
concurrently with the date of receipt by the Borrower or the Agent of any
Insurance Proceeds or Condemnation Proceeds in respect of such casualty or
Taking, as applicable, or as soon thereafter as is reasonably practicable, in
the amount required pursuant to the relevant provisions of Section 7.7 or such
Mortgage.

         Section 3.3 Optional Prepayments. The Borrower shall have the right, at
its election, to prepay the outstanding amount of the Loans, as a whole or in
part, at any time without penalty or premium; provided, that the full or partial
prepayment of the outstanding amount of any Eurodollar Rate Loans pursuant to
this Section 3.3 may be made only on the last day of the Interest Period
relating thereto except as otherwise required pursuant to Section 4.7. The
Borrower shall give the Agent, no later than 10:00 a.m., Boston time, at least
five (5) days prior written notice of any prepayment pursuant to this Section
3.3, in each case specifying the proposed date of prepayment of Loans and the
principal amount to be prepaid.

         Section 3.4 Partial Prepayments. Each partial prepayment of the Loans
under Section 3.3 shall be in a minimum amount of $1,000,000.00 or an integral
multiple of $100,000 in excess thereof, shall be accompanied by the payment of
accrued interest on the principal prepaid to the date of payment and shall be
applied, in the absence of instruction by the Borrower, first to the principal
of Base Rate Loans and then to the principal of Eurodollar Rate Loans.

         Section 3.5 Effect of Prepayments. Amounts of the Loans prepaid under
Section 3.2 and Section 3.3 prior to the Maturity Date may be reborrowed as
provided in Section 2.

         Section 3.6 Additional Payments. Each voluntary or mandatory prepayment
of the Loans pursuant to this Article shall be accompanied by the payment of (i)
accrued interest on the principal amount so prepaid to the date of prepayment,
and (ii) the amount, if any, required to be paid to the Lenders pursuant to
Section 4.8.

         Section 4 CERTAIN GENERAL PROVISIONS.

         Section 4.1 Conversion Options. (a) The Borrower may elect from time to
time to convert any of its outstanding Loans to a Loan of another Type and such
Loan shall thereafter bear


                                       23
<PAGE>

interest as a Base Rate Loan or a Eurodollar Rate Loan, as applicable; provided
that (i) with respect to any such conversion of a Eurodollar Rate Loan to a Base
Rate Loan, the Borrower shall give the Agent at least one (1) Business Day's
prior written notice of such election, and such conversion shall only be made on
the last day of the Interest Period with respect to such Eurodollar Rate Loan;
(ii) with respect to any such conversion of a Base Rate Loan to a Eurodollar
Rate Loan, the Borrower shall give the Agent at least three (3) Eurodollar
Business Days' prior written notice of such election and the Interest Period
requested for such Loan, the principal amount of the Loan so converted shall be
in a minimum aggregate amount of $2,000,000 or an integral multiple of $100,000
in excess thereof and, after giving effect to the making of such Loan, there
shall be no more than eight (8) Eurodollar Rate Loans outstanding at any one
time; and (iii) no Loan may be converted into a Eurodollar Rate Loan when any
Default or Event of Default has occurred and is continuing. All or any part of
the outstanding Loans of any Type may be converted as provided herein, provided
that no partial conversion shall result in a Base Rate Loan in a principal
amount of less than $1,000,000 or a Eurodollar Rate Loan in a principal amount
of less than $2,000,000 and that the principal amount of each Loan shall be in
an integral multiple of $100,000. On the date on which such conversion is being
made, each Lender shall take such action as is necessary to transfer its
Commitment Percentage of such Loans to its Domestic Lending Office or its
Eurodollar Lending Office, as the case may be. Each Conversion/Continuation
Request relating to the conversion of a Base Rate Loan to a Eurodollar Rate Loan
shall be irrevocable by the Borrower.

         (b) Any Eurodollar Rate Loan may be continued as such Type upon the
expiration of an Interest Period with respect thereto by compliance by the
Borrower with the terms of Section 4.1; provided that no Eurodollar Rate Loan
may be continued as such when any Default or Event of Default has occurred and
is continuing, but shall be automatically converted to a Base Rate Loan on the
last day of the Interest Period relating thereto ending during the continuance
of any Default or Event of Default.

         (c) In the event that the Borrower does not notify the Agent of its
election hereunder with respect to any Eurodollar Rate Loan, such Loan shall be
automatically converted to a Base Rate Loan at the end of the applicable
Interest Period.

         Section 4.2 Commitment Fee. The Borrower agrees to pay to BankBoston,
BancBoston Securities, Inc. and DLJ a commitment fee for services rendered or to
be rendered in connection with the Loans as provided pursuant to an Agreement
Regarding Fees dated as of even date herewith among the Borrower, REA,
BankBoston, BancBoston Securities, Inc. and DLJ. Such commitment fee shall be
solely for the account of BankBoston, BancBoston Securities, Inc. and DLJ as
provided in such Agreement Regarding Fees.

         Section 4.3 Agent's Fee. The Borrower shall pay to the Agent, for the
Agent's own account, an annual Agent's fee as provided in the Agreement
Regarding Fees. The Agent's fee shall be payable quarterly in arrears on the
first day of each calendar quarter for the immediately preceding calendar
quarter or portion thereof. The Agent's fee shall also be paid upon the Maturity
Date or earlier termination of the Commitments. The Agent's fee for any partial
quarter shall be prorated.


                                       24
<PAGE>

         Section 4.4 Funds for Payments. (a) All payments of principal,
interest, facility fees, closing fees and any other amounts due hereunder or
under any of the other Loan Documents shall be made to the Agent, for the
respective accounts of the Lenders and the Agent, as the case may be, at the
Agent's Head Office, not later than 1:00 p.m. (Boston time) on the day when due,
in each case in immediately available funds. The Agent is hereby authorized to
charge the accounts of the Borrower with BankBoston, on the dates when the
amount thereof shall become due and payable, with the amounts of the principal
of and interest on the Loans and all fees, charges, expenses and other amounts
owing to the Agent and/or the Lenders under the Loan Documents.

         (b) All payments by the Borrower hereunder and under any of the other
Loan Documents shall be made without setoff or counterclaim and free and clear
of and without deduction for any taxes (other than income or franchise taxes
imposed on any Lender), levies, imposts, duties, charges, fees, deductions,
withholdings, compulsory loans, restrictions or conditions of any nature now or
hereafter imposed or levied by any jurisdiction or any political subdivision
thereof or taxing or other authority therein unless the Borrower is compelled by
law to make such deduction or withholding; provided that no such payment shall
constitute a waiver of any rights that the Borrower may have hereunder. If any
such obligation is imposed upon the Borrower with respect to any amount payable
by it hereunder or under any of the other Loan Documents, the Borrower will pay
to the Agent, for the account of the Lenders or (as the case may be) the Agent,
on the date on which such amount is due and payable hereunder or under such
other Loan Document, such additional amount in Dollars as shall be necessary to
enable the Lenders or the Agent to receive the same net amount which the Lenders
or the Agent would have received on such due date had no such obligation been
imposed upon the Borrower. The Borrower will deliver promptly to the Agent
certificates or other valid vouchers for all taxes or other charges deducted
from or paid with respect to payments made by the Borrower hereunder or under
any other Loan Document.

         (c) Each Lender organized under the laws of a jurisdiction outside the
United States, if requested in writing by the Borrower (but only so long as such
Lender remains lawfully able to do so), shall provide the Borrower with such
duly executed form(s) or statement(s) which may, from time to time, be
prescribed by law and, which, pursuant to applicable provisions of (i) an income
tax treaty between the United States and the country of residence of such
Lender, (ii) the Code, or (iii) any applicable rules or regulations in effect
under (i) or (ii) above, indicates the withholding status of such Lender;
provided that nothing herein (including without limitation the failure or
inability to provide such form or statement) shall relieve the Borrower of its
obligations under Section 4.4(b). In the event that the Borrower shall have
delivered the certificates or vouchers described above for any payments made by
the Borrower and such Lender receives a refund of any taxes paid by the Borrower
pursuant to Section 4.4(b), such Lender will pay to the Borrower the amount of
such refund promptly upon receipt thereof; provided that if at any time
thereafter such Lender is required to return such refund, the Borrower shall
promptly repay to such Lender the amount of such refund.

         Section 4.5 Computations. All computations of interest on the Loans and
of other fees to the extent applicable shall be based on a 360-day year and paid
for the actual number of days elapsed. Except as otherwise provided in the
definition of the term "Interest Period" with respect to Eurodollar Rate Loans,
whenever a payment hereunder or under any of the other Loan



                                       25
<PAGE>

Documents becomes due on a day that is not a Business Day, the due date for such
payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension.

         Section 4.6 Inability to Determine Eurodollar Rate. In the event that,
prior to the commencement of any Interest Period relating to any Eurodollar Rate
Loan, the Agent shall determine that adequate and reasonable methods do not
exist for ascertaining the Eurodollar Rate for such Interest Period, the Agent
shall forthwith give notice of such determination (which shall be conclusive and
binding on the Borrower and the Lenders absent manifest error) to the Borrower
and the Lenders. In such event (a) any Loan Request with respect to a Eurodollar
Rate Loan shall be automatically withdrawn and shall be deemed a request for a
Base Rate Loan and (b) each Eurodollar Rate Loan will automatically, on the last
day of the then current Interest Period applicable thereto, become a Base Rate
Loan, and the obligations of the Lenders to make Eurodollar Rate Loans shall be
suspended until the Agent determines that the circumstances giving rise to such
suspension no longer exist, whereupon the Agent shall so notify the Borrower and
the Lenders.

         Section 4.7 Illegality. Notwithstanding any other provisions herein, if
any present or future law, regulation, treaty or directive or the interpretation
or application thereof shall make it unlawful, or any central bank or other
governmental authority having jurisdiction over a Lender or its Eurodollar
Lending Office shall assert that it is unlawful, for any Lender to make or
maintain Eurodollar Rate Loans, such Lender shall forthwith give notice of such
circumstances to the Agent and the Borrower and thereupon (a) the commitment of
the Lenders to make Eurodollar Rate Loans shall forthwith be suspended and (b)
the Eurodollar Rate Loans then outstanding shall be converted automatically to
Base Rate Loans on the last day of each Interest Period applicable to such
Eurodollar Rate Loans or within such earlier period as may be required by law.
Notwithstanding the foregoing, before giving such notice, the applicable Lender
shall designate a different lending office if such designation will void the
need for giving such notice and will not, in the judgment of such Lender, be
otherwise materially disadvantageous to such Lender.

         Section 4.8 Compensation. The Borrower shall compensate the Lenders,
upon the Agent's written request (which request shall set forth the basis for
requesting such compensation), for all reasonable losses, expenses and
liabilities (including, without limitation, any loss, expenses and liabilities
(incurred by reason of the liquidation or reemployment of deposits or other
funds required by the Lenders to fund Loans but excluding any loss of
anticipated profit with respect to such Loans) which the Lenders may sustain:
(i) if for any reason (other than a default by the Lenders) a borrowing of a
Loan does not occur on a date specified therefor in a notice of such borrowing
received from the Borrower (whether or not withdrawn by the Borrower or deemed
withdrawn pursuant to Section 4.6); (ii) if any repayment or prepayment of a
Eurodollar Rate Loan occurs on a date which is not the last day of an Interest
Period applicable thereto; (iii) if any prepayment of any Loan is not made on
any date specified in a notice of prepayment given by the Borrower; or (iv) as a
consequence of (x) any other Default by the Borrower to repay Loans when
required by the terms of this Agreement or (y) an election made pursuant to
Section 4.1.

         Section 4.9 Additional Costs, Etc. Notwithstanding anything herein to
the contrary, if any present or future applicable law, which expression, as used
herein, includes statutes, rules and regulations thereunder and interpretations
thereof by any competent court or by any governmental or other regulatory body
or official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Lender or the Agent by any
central bank or other fiscal, monetary or other authority (whether or not having
the force of law), shall:

                  (a) subject any Lender or the Agent to any tax, levy, impost,
         duty, charge, fee, deduction or withholding of any nature with respect
         to this Agreement, the other Loan Documents, such Lender's Commitment
         or the Loans (other than taxes based upon or measured by the income or
         profits of such Lender or the Agent or its franchise tax), or

                  (b) materially change the basis of taxation (except for
         changes in taxes on income or profits) of payments to any Lender of the
         principal of or the interest on any Loans or any other amounts payable
         to any Lender under this Agreement or the other Loan Documents, or

                  (c) impose or increase or render applicable any special
         deposit, reserve, assessment, liquidity, capital adequacy or other
         similar requirements (whether or not having the force of law and which
         are not already reflected in any amounts payable by Borrower hereunder)
         against assets held by, or deposits in or for the account of, or loans
         by, or commitments of an office of any Lender, or

                  (d) impose on any Lender or the Agent any other conditions or
         requirements with respect to this Agreement, the other Loan Documents,
         the Loans, such Lender's Commitment, or any class of loans or
         commitments of which any of the Loans or such Lender's Commitment forms
         a part;

and the result of any of the foregoing is:

                  (i) to increase the cost to any Lender of making, funding,
         issuing, renewing, extending or maintaining any of the Loans or such
         Lender's Commitment, or

                  (ii) to reduce the amount of principal, interest or other
         amount payable to any Lender or the Agent hereunder on account of such
         Lender's Commitment or any of the Loans, or

                  (iii) to require any Lender or the Agent to make any payment
         or to forego any interest or other sum payable hereunder, the amount of
         which payment or foregone interest or other sum is calculated by
         reference to the gross amount of any sum receivable or deemed received
         by such Lender or the Agent from the Borrower hereunder,



                                       27
<PAGE>

then, and in each such case, the Borrower will, within fifteen (15) days of
demand made by such Lender or (as the case may be) the Agent at any time and
from time to time and as often as the occasion therefor may arise, pay to such
Lender or the Agent such additional amounts as such Lender or the Agent shall
determine in good faith to be sufficient to compensate such Lender or the Agent
for such additional cost, reduction, payment or foregone interest or other sum.
Each Lender and the Agent in determining such amounts may use any reasonable
averaging and attribution methods generally applied by such Lender or the Agent.

         Section 4.10 Capital Adequacy. If after the date hereof any Lender
determines that (a) the adoption of or change in any law, rule, regulation or
guideline regarding capital requirements for banks or bank holding companies or
any change in the interpretation or application thereof by any governmental
authority charged with the administration thereof, or (b) compliance by such
Lender or its parent bank holding company with any guideline, request or
directive of any such entity regarding capital adequacy (whether or not having
the force of law), has the effect of reducing the return on such Lender's or
such holding company's capital as a consequence of such Lender's commitment to
make Loans hereunder to a level below that which such Lender or holding company
could have achieved but for such adoption, change or compliance (taking into
consideration such Lender's or such holding company's then existing policies
with respect to capital adequacy and assuming the full utilization of such
entity's capital) by any amount deemed by such Lender to be material, then such
Lender may notify the Borrower thereof. The Borrower agrees to pay to such
Lender the amount of such reduction in the return on capital as and when such
reduction is determined, upon presentation by such Lender of a statement of the
amount setting forth the Lender's calculation thereof. In determining such
amount, such Lender may use any reasonable averaging and attribution methods
generally applied by such Lender.

         Section 4.11 Intentionally omitted.

         Section 4.12 Interest on Overdue Amounts; Late Charge. Overdue
principal and (to the extent permitted by applicable law) overdue interest on
the Loans and all other overdue amounts payable hereunder or under any of the
other Loan Documents shall bear interest payable on demand at a rate per annum
equal to four percent (4.0%) above the Base Rate until such amount shall be paid
in full (after as well as before judgment). In addition, the Borrower shall pay
a late charge equal to three percent (3%) of any amount of interest and/or
principal payable on the Loans or any other amounts payable hereunder or under
the Loan Documents, which is not paid by the Borrower within ten (10) days of
the date when due.

         Section 4.13    Intentionally Omitted.

         Section 4.14 Certificate. A certificate setting forth any amounts
payable pursuant to Section 4.8, Section 4.9, Section 4.10, or Section 4.12 and
a reasonably detailed explanation of such amounts which are due, submitted by
any Lender or the Agent to the Borrower, shall be conclusive in the absence of
manifest error.

         Section 4.15 Limitation on Interest. Notwithstanding anything in this
Agreement or the other Loan Documents to the contrary, all agreements between or
among the Borrower, REA, the Guarantors, the Lenders and the Agent, whether now
existing or hereafter arising and whether



                                       28
<PAGE>

written or oral, are hereby limited so that in no contingency, whether by reason
of acceleration of the maturity of any of the Obligations or otherwise, shall
the interest contracted for, charged or received by the Lenders exceed the
maximum amount permissible under applicable law. If, from any circumstance
whatsoever, interest would otherwise be payable to the Lenders in excess of the
maximum lawful amount, the interest payable to the Lenders shall be reduced to
the maximum amount permitted under applicable law; and if from any circumstance
the Lenders shall ever receive anything of value deemed interest by applicable
law in excess of the maximum lawful amount, an amount equal to any excessive
interest shall be applied to the reduction of the principal balance of the
Obligations and to the payment of interest or, if such excessive interest
exceeds the unpaid balance of principal of the Obligations, such excess shall be
refunded to the Borrower. All interest paid or agreed to be paid to the Lenders
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread throughout the full period until payment in full of the
principal of the Obligations (including the period of any renewal or extension
thereof) so that the interest thereon for such full period shall not exceed the
maximum amount permitted by applicable law. This section shall control all
agreements between or among the Borrower, REA, the Guarantors, the Lenders and
the Agent.

         Section 5 COLLATERAL SECURITY.

         Section 5.1 Collateral. The Obligations shall be secured by (i) a
perfected first priority lien to be held by the Agent for the benefit of the
Lenders on the Mortgaged Properties, pursuant to the terms of the Mortgages,
(ii) a perfected first priority security interest to be held by the Agent for
the benefit of the Lenders in the Leases pursuant to the terms of the
Assignments of Leases and Rents and (iii) the Indemnity Agreements and the other
Security Documents.

         Section 5.2 Appraisals. (a) The Agent on behalf of the Lenders shall
require Appraisals of each of the Mortgaged Properties, which will be ordered by
the Agent and reviewed and approved by the appraisal department of the Agent
from time to time, in order to determine the current Appraised Value and
Borrowing Base of each Mortgaged Property, and the Borrower shall pay to the
Agent on demand all reasonable out-of-pocket costs of all such Appraisals
relating to the Mortgaged Properties (which costs shall include any reasonable
internal appraisal review fees of the Agent); provided, however, that so long as
no Default or Event of Default shall have occurred and be continuing and
regulatory requirements of any Lender generally applicable to real estate loans
of the category made under this Agreement as reasonably interpreted by such
Lender shall not require more frequent Appraisals, and except as otherwise
provided in Section 5.2(b) or Section 5.2(e), the Borrower shall not be required
to pay for an Appraisal for a particular Mortgaged Property more often than once
in any twenty-four (24) month period, with the result that, except as otherwise
provided in Section 5.2(b) or Section 5.2(e), the first Appraisal of a Mortgaged
Property for which the Borrower shall be financially responsible shall not be
required prior to the date which is twenty-four (24) months from the date of
initial Appraisal for such Mortgaged Property delivered to the Agent pursuant to
this Agreement.

         (b) Notwithstanding the provisions of Section 5.2(a), the Agent on
behalf of the Lenders may, for the purpose of determining the current Appraised
Value and Borrowing Base of a Mortgaged Property, obtain (and the Borrower shall
pay to the Agent on demand all reasonable out-of-pocket costs (which costs shall
include any reasonable internal appraisal review fees of the



                                       29

Agent) of an Appraisal (or an update of the existing Appraisal) of such
Mortgaged Property (i) at any time that the regulatory requirements of a Lender
generally applicable to real estate loans of the category made under this
Agreement as reasonably interpreted by such Lender shall require an Appraisal,
or (ii) at any time following: (x) a condemnation of or a casualty affecting
more than twenty five percent 25% of the Net Rentable Area of such Mortgaged
Property, (y) the termination or expiration of Leases affecting more than twenty
five percent (25%) of the Net Rentable Area of such Mortgaged Property or (z)
the occurrence of a material adverse change with respect to such Mortgaged
Property as determined by the Majority Lenders in the exercise of their good
faith business judgment. If an Appraisal (or an update of the existing
Appraisal) is being done in respect of a Mortgaged Property that has been
affected by a condemnation or casualty which is being restored in accordance
with the relevant provisions of Section 7.7 hereof or the Mortgage encumbering
such Mortgaged Property, such Appraisal (or an update of the existing Appraisal)
shall, at the election of the Agent on behalf of the Lenders, either (A) be
undertaken only following the completion of such restoration or (B) take into
account the fact that such restoration has not been completed and be prepared on
an "as-built" basis, based on the plans and specifications for such restoration;
and in either such case any such Appraisal (or an update of the existing
Appraisal) shall take into account any termination of any Leases that have
occurred as a result of such condemnation or casualty.

         (c) In the event that the Agent shall advise the Borrower, on the basis
of any Appraisal (or update of an existing Appraisal), that the Borrowing Base
is insufficient to comply with the requirements of Section 9.1, then until the
Borrowing Base is increased or the outstanding principal amount of the Loans is
reduced such that the Borrowing Base is in compliance with Section 9.1, the
Lenders shall not be required to make advances under Section 2.1.

         (d) The Borrower, REA and each Guarantor acknowledge that the Agent may
make changes or adjustments to the value set forth in any Appraisal (or update
of an existing Appraisal) at the time such Appraisal (or update of an existing
Appraisal) is received as may be required by the appraisal department of the
Agent in its good faith business judgment, and that the Lenders are not bound by
the value set forth in any Appraisal performed pursuant to this Agreement and do
not make any representations or warranties with respect to any such Appraisal.
The Borrower, REA and each Guarantor further agree that the Lenders shall have
no liability as a result of or in connection with any Appraisal (or update of an
existing Appraisal) for statements contained in such Appraisal (or update of an
existing Appraisal), including without limitation, the accuracy and completeness
of information, estimates, conclusions and opinions contained in such Appraisal
(or update of an existing Appraisal), or variance of such Appraisal (or update
of an existing Appraisal) from the fair value of the Mortgaged Property that is
the subject of such Appraisal (or update of an existing Appraisal) given by the
local tax assessor's office, or the Borrower's, REA's or each Guarantor's idea
of the value of the Mortgaged Property.

         (e) If requested to do so by the Borrower following the completion of a
Capital Improvement Project at a Mortgaged Property, the Agent shall obtain, at
the sole cost and expense of the Borrower, an Appraisal (or an update of the
existing Appraisal) of such Mortgaged Property, and the Appraised Value as
determined based on such new or updated Appraisal shall be used in order to
determine the Borrowing Base of such Mortgaged Property.

         Section 5.3 Replacement or Addition of Mortgaged Properties. After the
Closing Date, the Borrower shall have the right, subject to the consent of the
Majority Lenders and the satisfaction by the Borrower of the conditions set
forth in this Section 5.3, to add Potential Collateral to the Collateral or to
replace any Mortgaged Property which is Collateral with Potential Collateral.
Subject to Section 7.17, the Borrower from time to time after the Closing Date
may also request that certain Real Estate of one or more of its wholly-owned
Subsidiaries (collectively, the "Subsidiary Collateral") be included as a
Mortgaged Property for the purpose of increasing the Borrowing Base or replacing
existing Collateral. In the event the Borrower desires to replace Collateral or
add additional Potential Collateral or Subsidiary Collateral as aforesaid, the
Borrower shall provide written notice to the Agent of such request (which the
Agent shall promptly furnish to the Lenders), together with all documentation
and other information required to permit the Agent to determine whether such
Real Estate is Eligible Real Estate. Thereafter, the Agent shall have fifteen
(15) days from the date of the receipt of such documentation and other
information to advise the Borrower whether the Majority Lenders consent to the
acceptance of such Subsidiary Collateral or Potential Collateral.
Notwithstanding the foregoing, no Subsidiary Collateral or Potential Collateral
shall be included as Collateral unless and until the following conditions
precedent shall have been satisfied:

                  (i) such Subsidiary Collateral or Potential Collateral shall
         be Eligible Real Estate;

                  (ii) the owner or lessee of any Subsidiary Collateral shall
         have executed a Guaranty of the Obligations in form and substance
         satisfactory to the Agent, or, in the Agent's sole discretion, shall
         have been added as an additional Borrower hereunder pursuant to an
         amendment to this Agreement in form and substance satisfactory to the
         Agent and Agent's counsel;

                  (iii) the Borrower or the owner or lessee of the Subsidiary
         Collateral or Potential Collateral, as applicable, shall have executed
         and delivered to the Agent all Eligible Real Estate Qualification
         Documents, all of which instruments, documents or agreements shall be
         in form and substance satisfactory to the Agent in its sole discretion;
         and

                  (iv) after giving effect to the inclusion of such Subsidiary
         Collateral or Potential Collateral, each of the representations and
         warranties made by or on behalf of the Borrower, REA or the Guarantors
         or any of their respective Subsidiaries contained in this Agreement,
         the other Loan Documents or in any document or instrument delivered
         pursuant to or in connection with this Agreement shall be true in all
         material respects both as of the date as of which it was made and shall
         also be true as of the time of the replacement or addition of Mortgaged
         Properties, with the same effect as if made at and as of that time (it
         being understood and agreed that any representation or warranty which
         by its terms is made as of a specified date shall be required to be
         true and correct only as of such specified date), and no Default or
         Event of Default shall have occurred and be continuing, and each of the
         Lenders shall have received a certificate of the Borrower and REA
         signed by an authorized representative of the Borrower and REA to such
         effect.



                                       31
<PAGE>

         The Borrower acknowledges that the decision of the Majority Lenders to
grant or withhold their consent to the acceptance of Subsidiary Collateral or
Potential Collateral under this Section 5.3 shall be based entirely on such
factors as the Lenders deem relevant in their sole discretion, including,
without limitation, those enumerated in clauses (i) through (iv) hereinabove,
and such consent may be granted or withheld solely at the discretion of the
Majority Lenders.

         In connection with each such addition or substitution, the Borrower,
within fifteen (15) days of the Borrower's request to add such assets to the
Collateral, shall pay to the Agent for the account of the Lenders a review fee
of $7,500 for each asset to be added or replaced, which review fee shall be
split equally among the Lenders, without regard to their respective Commitment
Percentages.

         Section 5.4 Release of Mortgaged Property. Provided no Default or Event
of Default shall have occurred hereunder and be continuing (or would exist
immediately after giving effect to the transactions contemplated by this Section
5.4), the Agent shall release a Mortgaged Property from the lien or security
title of the Security Documents encumbering the same upon the request of the
Borrower subject to and upon the following terms and conditions:

                  (a) the Agent shall determine that the Mortgaged Properties
         remaining following such release (i) have a Borrowing Base of not less
         than $25,000,000 and (ii) are otherwise satisfactory to the Majority
         Lenders in their good faith business judgment;

                  (b) the Borrower shall deliver to the Agent written notice of
         its desire to obtain such release no later than fifteen (15) days prior
         to the date on which such release is to be effected;

                  (c) the Borrower shall submit to the Agent with such request a
         Compliance Certificate prepared using the financial statements of REA
         most recently provided or required to be provided to the Agent under
         Section 6.4 or Section 7.4 adjusted in the best good faith estimate of
         the Borrower to give effect to the proposed release and demonstrating
         that no Default or Event of Default with respect to the covenants
         referred to therein shall exist after giving effect to such release;

                  (d) all release documents to be executed by the Agent shall be
         in form and substance reasonably satisfactory to the Agent;

                  (e) the Borrower shall pay all reasonable costs and expenses
         of the Agent in connection with such release, including without
         limitation, reasonable attorney's fees;

                  (f) the Borrower shall pay to the Agent for the account of the
         Lenders a release price, which payment shall be applied to reduce the
         outstanding principal balance of the Loans in an amount equal to the
         amount which is necessary to



                                       32
<PAGE>

         reduce the outstanding principal balance of the Loans so that no
         Default or Event of Default shall exist under Section 9 following such
         release;

                  (g) at no time during the term of this Agreement shall there
         be less than five (5) Mortgaged Properties securing the Obligations;
         and

                  (h) any release of a Mortgaged Property after January 1, 1999
         will not cause the aggregate Borrowing Base of the remaining Mortgaged
         Properties which are located in any one Metropolitan Statistical Area
         to equal or exceed forty percent (40%) of the aggregate Borrowing Base
         of all of the Mortgaged Properties.

                  (d) Neither the Borrower, REA, any Guarantor, their respective
         Subsidiaries nor the Real Estate is subject to any applicable
         Environmental Law requiring the performance of Hazardous Substances
         site assessments, or the removal or remediation of Hazardous

         Section 6.21 Intentionally omitted.

         Section 6.22 Leases. The Borrower has delivered to the Agent true
copies of the Leases relating to each Mortgaged Property required to be
delivered as a part of the Eligible Real Estate Qualification Documents as of
the date hereof.

         Section 6.23 Intentionally omitted.

         Section 6.24 Mortgaged Property. The Borrower and REA make the
following representations and warranties concerning each of the Mortgaged
Properties:

                  (a) Off-Site Utilities. All water, sewer, electric, gas,
         telephone and other utilities necessary for the use and operation of
         the Mortgaged Property are installed to the property lines of the
         Mortgaged Property through dedicated public rights-of-way or through
         perpetual private easements approved by the Agent with respect to which
         the applicable Mortgage creates a valid and enforceable first lien or
         security title and, except in the case of drainage facilities, are
         connected to the Building located thereon with valid permits and are
         adequate to service the Building in compliance with applicable law.

                  (b) Access, Etc. The streets abutting the Mortgaged Property
         are dedicated and accepted public roads, to which the Mortgaged
         Property has direct access by trucks and other motor vehicles and by
         foot, or are perpetual private ways or easements (with direct access by
         trucks and other motor vehicles and by



                                       39
<PAGE>

         foot to public roads) to which the Mortgaged Property has direct access
         approved by the Agent and with respect to which the applicable Mortgage
         creates a valid and enforceable first lien or security title. All
         private ways or easements providing access to the Mortgaged Property
         are zoned in a manner which will permit access to the Building over
         such ways or easements by trucks and other commercial and industrial
         vehicles.

                  (c) Independent Building. The Building is fully independent in
         all respects including, without limitation, in respect of structural
         integrity, heating, ventilating and air conditioning, plumbing,
         mechanical and other operating and mechanical systems, and electrical,
         sanitation and water systems, all of which are connected directly to
         off-site utilities located in public streets or ways or through insured
         perpetual private easements approved by the Agent. The Building is
         located on a lot which is separately assessed for purposes of real
         estate tax assessment and payment. The Building, all Personal Property
         and all paved or landscaped areas related to or used in connection with
         the Building are located wholly within the perimeter lines of the lot
         or lots on which the Mortgaged Property is located, except as may be
         specifically shown on the Survey for such Mortgaged Property.

                  (d) Condition of Building. To the best of the knowledge and
         belief of the Borrower and REA, the Building is structurally sound, in
         good repair and free of defects in materials and workmanship. To the
         best of the knowledge and belief of the Borrower and REA, all major
         building systems located within the Building, including without
         limitation heating, ventilating and air conditioning, electrical,
         sprinkler, plumbing or other mechanical systems (but excluding any
         systems which are required to be maintained by tenants), are in good
         working order and condition. To the best of the knowledge and belief of
         the Borrower and REA, since the date of the property condition reports
         delivered to the Agent prior to the date hereof, there has been no
         materially adverse change to the physical condition of any of the
         Mortgaged Property, including as a result of any fire, explosion,
         accident, flood or other casualty.

                  (e) Building Compliance with Law. Neither the Borrower, REA
         nor any Guarantor has received any notice of, and has no knowledge of,
         any violation by the Building as presently constructed, used, occupied
         and operated any applicable federal or state law or governmental
         regulation, or any local ordinance, order or regulation, including but
         not limited to laws, regulations, or ordinances relating to zoning,
         building use and occupancy, subdivision control, fire protection,
         health, sanitation, safety, handicapped access, tidelands, wetlands and
         flood control (hereinafter referred to as the "Requirements"). The
         Building complies with applicable zoning laws and regulations and is
         not a so-called non-conforming use. The zoning laws permit use of the
         Building for its current use. There is such number of parking spaces on
         the lot or lots on which the Mortgaged Property is located as is
         adequate under the zoning laws and regulations to permit use of the
         Building for its current use. Each Mortgaged



                                       40
<PAGE>

         Property constitutes a separate parcel which has been properly
         subdivided in accordance with all applicable state and local laws,
         regulations and ordinances to the extent required thereby, and neither
         the execution and delivery of the Mortgages nor the exercise of any
         remedies thereunder by Agent shall violate any such law or regulation
         relating to the subdivision of real property.

                  (f) No Required Mortgaged Property Consents, Permits, Etc.
         Neither the Borrower, REA nor any Guarantor has received any notice of,
         and has no knowledge of, any approvals, consents, licenses, permits
         issued by any governmental or quasi-governmental authority, utility
         installations and connections (including, without limitation, drainage
         facilities), curb cuts and street openings, required by applicable
         laws, rules, ordinances or regulations or any agreement affecting the
         Mortgaged Property for the maintenance, operation, servicing and use of
         the Mortgaged Property or the Building for its current use (hereinafter
         referred to as the "Project Approvals") which have not been granted,
         effected, or performed and completed (as the case may be), or any fees
         or charges therefor which have not been fully paid, or which are no
         longer in full force and effect. No Project Approvals (including,
         without limitation, any railway siding agreements) will terminate, or
         become void or voidable or terminable on any foreclosure sale of the
         Mortgaged Property pursuant to the Mortgage. To the best knowledge of
         the Borrower and REA, there are no outstanding notices, suits, orders,
         decrees or judgments relating to zoning, building use and occupancy,
         fire, health, sanitation or other violations affecting, against, or
         with respect to, the Mortgaged Property or any part thereof.

                  (g) No Violations. Neither the Borrower, REA nor any Guarantor
         has received written notice of, nor has any knowledge of, any violation
         of any applicable Requirements, Project Approvals or any other
         restrictions or agreements by which the Borrower, Guarantor or the
         Mortgaged Property is bound.

                  (h) Insurance. Neither the Borrower, REA nor any Guarantor has
         received any written notice from any insurer or its agent requiring
         performance of any work with respect to the Mortgaged Property or
         canceling or threatening to cancel any policy of insurance, and the
         Mortgaged Property complies with the requirements of all of the
         relevant insurance carriers of the Borrower, REA and the Guarantors.

                  (i) Real Property and other Taxes; Special Assessments. There
         are no unpaid or outstanding real estate or other taxes or assessments
         on or against the Mortgaged Property or any part thereof which are
         payable by the Borrower, REA or any Guarantor (except real estate or
         other taxes or assessments that are not yet delinquent or subject to
         any penalties, interest or other late charges or which are being
         contested in good faith by appropriate proceedings and for which the
         Borrowers, REA or such Guarantor has set aside reserves adequate to pay
         same). There are no unpaid or outstanding gross receipts, rent or sales
         taxes payable by the Borrower, REA or any Guarantor with respect to the
         use and operation of the



                                       41
<PAGE>

         Mortgaged Property which are due and payable. The Borrower has
         delivered to the Agent true and correct copies of real estate tax bills
         for the Mortgaged Property for the past three fiscal tax years. No
         abatement proceedings are pending with reference to any real estate
         taxes assessed against the Mortgaged Property. To the best of the
         knowledge and belief of the Borrower and REA, there are no betterment
         assessments or other special assessments presently pending with respect
         to any portion of the Mortgaged Property, and neither the Borrower, REA
         nor any Guarantor has received any written notice of any such special
         assessment being contemplated.

                  (j) Historic Status. The Building is not a historic structure
         or landmark and neither the Building nor the Mortgaged Property is
         located within any historic district pursuant to any federal, state or
         local law or governmental regulation.

                  (k) Eminent Domain; Casualty. Except as set forth on Schedule
         6.24(k) hereto, there are no pending eminent domain proceedings against
         the Mortgaged Property or any part thereof, and, to the best of the
         knowledge and belief of the Borrower and REA no such proceedings are
         presently threatened or contemplated by any taking authority. Neither
         the Mortgaged Property, the Building nor any part thereof is now
         materially damaged or injured as a result of any fire, explosion,
         accident, flood or other casualty.

                  (l) Leases. An accurate and complete Rent Roll and Lease
         Summary as of the date of inclusion of each Mortgaged Property in the
         Collateral (or such other recent date as may be required by the Agent)
         with respect to all Leases of any portion of the Mortgaged Property has
         been provided to the Agent. The Leases reflected on such Rent Roll
         constitute as of the date thereof the sole agreements relating to
         leasing or licensing of space at such Mortgaged Property and in the
         Building relating thereto. None of the Leases has been modified,
         changed, altered, assigned, supplemented or amended in any respect,
         except as reflected on the Rent Roll, and no tenant is entitled to any
         free rent, partial rent, rebate of rent payments, credit, offset or
         deduction in rent, including, without limitation, lease support
         payments or lease buy-outs, except as reflected in the Rent Roll. There
         are no occupancies, rights, privileges or licenses in or to any
         Mortgaged Property or portion thereof other than pursuant to the Leases
         reflected in Rent Rolls previously furnished to the Agent for such
         Mortgaged Property. Except as set forth in each Rent Roll, the Leases
         reflected therein are in full force and effect in accordance with their
         respective terms, without any payment default or any other material
         default thereunder, nor are there any defenses, counterclaims, offsets,
         concessions or rebates available to any tenant thereunder, and neither
         the Borrower, REA nor any Guarantor has given or made, any notice of
         any payment or other material default, or any claim, which remains
         uncured or unsatisfied, with respect to any of the Leases, and to the
         best of the knowledge and belief of the Borrower and REA, there is no
         basis for any such claim or notice of default by any tenant. No
         property other than the Mortgaged Property which is



                                       42
<PAGE>

         the subject of the applicable Lease is necessary to comply with the
         requirements (including, without limitation, parking requirements)
         contained in such Lease. The Rent Rolls furnished to the Agent
         accurately and completely set forth all rents payable by and security,
         if any, deposited by tenants, no tenant having paid more than one
         month's rent in advance. Except as described in Schedule 6.24(l)
         attached hereto, all tenant improvements or work to be done, furnished
         or paid for by the Borrower, REA or any Guarantor, or credited or
         allowed to a tenant, for, or in connection with, the Building pursuant
         to any Lease has been completed and paid for or provided for in a
         manner satisfactory to the Agent, and, except as set forth on Schedule
         6.24(l), no material leasing, brokerage or like commissions, fees or
         payments are due from the Borrower in respect of the Leases.

                  (m) Management Agreement. On and as of the Closing Date, the
         Mortgaged Properties are self managed by the Borrower and no Management
         Agreements with any third party or Affiliate exist.

                  (n) Other Material Real Property Agreements; No Options. There
         are no material agreements pertaining to the Mortgaged Property, any
         Building thereon or the operation or maintenance of either thereof
         other than as described in this Agreement (including the Schedules
         hereto) or otherwise disclosed in writing to the Agent and the Lenders
         by the Borrower, REA or any Guarantor; and no person or entity has any
         right or option to acquire the Mortgaged Property or any Building
         thereon or any portion thereof or interest therein.

         Section 6.25 Brokers. Neither the Borrower, REA, any Guarantor nor any
of their respective Subsidiaries has engaged or otherwise dealt with any broker,
finder or similar entity in connection with this Agreement or the Loans
contemplated hereunder.

         Section 6.26 Ownership. REA is the sole general partner of the Borrower
and as of the date hereof owns a 50.7% partnership interest in the Borrower. All
of the limited partners of the Borrower as of the date hereof are set forth on
Schedule 6.26 hereto. All of the Subsidiaries of the Borrower, REA and the
Guarantors as of the date hereof are set forth on Schedule 6.26. The form and
jurisdiction of organization of, and the ownership interests of the Borrower,
REA and each Guarantor in, each of their respective Subsidiaries as of the date
hereof are set forth in said Schedule 6.26. As of the date hereof, neither the
Borrower, REA or any Guarantor owns any interest in any joint ventures or other
entities which are not Subsidiaries.

         Section 6.27 Other Debt. Neither the Borrower, REA, any Guarantor nor
any of their respective Subsidiaries is in default of the payment of any
Indebtedness or any other agreement, mortgage, deed of trust, security
agreement, financing agreement, indenture or lease to which any of them is a
party. Neither the Borrower, REA nor any Guarantor is a party to or bound by any
agreement, instrument or indenture that may require the subordination in right
or time or payment of any of the Obligations to any other indebtedness or
obligation of the Borrower, REA or any Guarantor. Schedule 6.27 hereto sets
forth all agreements, mortgages, deeds of trust, financing agreements or other
material agreements binding upon the Borrower, REA and each Guarantor or their
respective properties and entered into by the Borrower, REA and or such



                                       43
<PAGE>

Guarantor as of the date of this Agreement with respect to any Indebtedness of
the Borrower, REA or any Guarantor, and the Borrower has provided the Agent with
true, correct and complete copies thereof.

         Section 6.28 Solvency. As of the Closing Date and after giving effect
to the transactions contemplated by this Agreement and the other Loan Documents,
including all Loans made or to be made hereunder, neither the Borrower, REA nor
any Guarantor is insolvent on a balance sheet basis such that the sum of such
Person's assets exceeds the sum of such Person's liabilities, each of the
Borrower, REA and each Guarantor is able to pay its debts as they become due,
and each of the Borrower, REA and each Guarantor has sufficient capital to carry
on its business.

         Section 6.29 No Bankruptcy Filing. None of the Borrower, REA or any
Guarantor is contemplating either the filing of a petition by it under any state
or federal bankruptcy or insolvency laws or the liquidation of its assets or
property, and neither the Borrower nor REA has knowledge of any Person
contemplating the filing of any such petition against it or any Guarantor.

         Section 6.30 No Fraudulent Intent. Neither the execution and delivery
of this Agreement or any of the other Loan Documents nor the performance of any
actions required hereunder or thereunder is being undertaken by the Borrower,
REA or any Guarantor with or as a result of any actual intent by any of such
Persons to hinder, delay or defraud any entity to which any of such Persons is
now or will hereafter become indebted.

         Section 6.31 Transaction in Best Interests of Borrower; Consideration.
The transaction evidenced by this Agreement and the other Loan Documents is in
the best interests of the Borrower, REA and each Guarantor and the creditors of
such Persons. The direct and indirect benefits to inure to the Borrower, REA and
each Guarantor pursuant to this Agreement and the other Loan Documents
constitute substantially more than "reasonably equivalent value" (as such term
is used in Section 548 of the Bankruptcy Code) and "valuable consideration,"
"fair value," and "fair consideration," (as such terms are used in any
applicable state fraudulent conveyance law), in exchange for the benefits to be
provided by the Borrower, REA and each Guarantor pursuant to this Agreement and
the other Loan Documents, and but for the willingness of REA and each Guarantor
to guaranty the Loan, the Borrower would be unable to obtain the financing
contemplated hereunder which financing will enable the Borrower, REA, each
Guarantor and their respective Subsidiaries to have available financing to
conduct and expand their business.

         Section 7 AFFIRMATIVE COVENANTS.

         Each of the Borrower and REA covenants and agrees that, so long as any
Loan or Note is outstanding or any Lender has any obligation to make any Loans:

         Section 7.1 Punctual Payment. The Borrower will duly and punctually pay
or cause to be paid the principal and interest on the Loans and all interest and
fees provided for in this Agreement, all in accordance with the terms of this
Agreement and the Notes, as well as all other sums owing pursuant to the Loan
Documents.



                                       44

         Section 7.2 Maintenance of Office. The Borrower, REA and each Guarantor
will maintain its respective chief executive office at 620 West Germantown Pike,
Plymouth Meeting, Pennsylvania 19462, or at such other place in the United
States of America as the Borrower, REA or any Guarantor shall designate upon
thirty (30) days prior written notice to the Agent and the Lenders, where
notices, presentations and demands to or upon the Borrower, REA or such

Real Estate is located and having a rating in Best's Key Rating Guide of at
least "A" and a financial size category of at least "VIII".

         (d) Neither the Borrower, REA, any Guarantor nor any of their
respective Subsidiaries shall carry separate insurance, concurrent in kind or
form or contributing in the event of loss, with any insurance required under
this Agreement unless such insurance complies with the terms and provisions of
this Section 7.7.

         (e) In the event of any loss or damage to the Mortgaged Property, the
Borrower, REA or the applicable Guarantor shall give prompt written notice to
the insurance carrier and the Agent, and the Agent shall furnish a copy of such
notice promptly to each of the Lenders. Each of the Borrower, REA and the
Guarantors hereby irrevocably authorizes and empowers the Agent, at the Agent's
option and in the Agent's sole discretion or at the request of the Majority
Lenders in their sole discretion, as its attorney in fact, to make proof of such
loss, to adjust and compromise any claim under insurance policies, to appear in
and prosecute any action arising from such insurance policies, to collect and
receive Insurance Proceeds, and to deduct therefrom the Agent's expenses
incurred in the collection of such Insurance Proceeds; provided, however, that
so long as no Default or Event of Default has occurred and is continuing and so
long as the Borrower, REA or any Guarantor shall in good faith diligently pursue
such claim, the Borrower, REA or such Guarantor may make proof of loss and
appear in any proceedings or negotiations with respect to the adjustment of such
claim, except that the Borrower, REA or such Guarantor may not settle, adjust or
compromise any such claim without the prior written consent of the Agent, which
consent shall not be unreasonably withheld or delayed; provided, further, that
the Borrower, REA or such Guarantor may make proof of loss and adjust and
compromise any claim under casualty insurance policies which is in an amount
less than $500,000 so long as no Default or Event of Default has occurred and is
continuing and so long as the Borrower, REA or such Guarantor shall in good
faith diligently pursue such claim. The Borrower, REA and each Guarantor further
authorize the Agent, at the Agent's option, to (i) apply the balance of such
Insurance Proceeds to the payment of the Obligations whether or not then due, or
(ii) if the Agent shall require the reconstruction or repair of the Mortgaged
Property, to hold the balance of such proceeds as trustee to be used to pay
taxes, charges, sewer use fees, water rates and assessments which may be imposed
on the Mortgaged Property and the Obligations as they become due during the
course of reconstruction or repair of the Mortgaged Property and to reimburse
the Borrower, REA or such Guarantor, in accordance with such terms and
conditions as the Agent may prescribe, for the costs of reconstruction or repair
of the Mortgaged Property, and upon completion of such reconstruction or repair
to apply any excess to the payment of the Obligations. Notwithstanding the
foregoing, the Agent shall make such net Insurance Proceeds available to the
Borrower, REA or such Guarantor to reconstruct and repair the Mortgaged
Property, in accordance with such terms and conditions as the Agent may
prescribe in the Agent's discretion for the disbursement of the proceeds,
provided that (i) the cost of such reconstruction or repair is not estimated by
the Agent to exceed twenty five percent (25%) of the replacement cost of the
damaged Building (as reasonably estimated by the Agent), (ii) no Event of
Default shall have occurred and be continuing, (iii) the Borrower, REA or such
Guarantor shall have provided to the Agent additional cash security in an amount
equal to the amount reasonably estimated by the Agent to be the amount in excess
of such proceeds which will be required to complete such repair or restoration,
(iv) the Agent shall have approved the plans and



                                       53
<PAGE>

specifications, construction budget, construction contracts, and construction
schedule for such repair or restoration and reasonably determined that the
repaired or restored Mortgaged Property will provide the Agent with adequate
security for the Obligations (provided that the Agent shall not disapprove such
plans and specifications if the Building is to be restored to its condition
immediately prior to such damage), (v) the Borrower, REA or such Guarantor shall
have delivered to the Agent written agreements binding upon not less than
seventy-five percent (75%) of the tenants or other parties having present or
future rights to possession of any portion of the affected Mortgaged Property or
having any right to require repair, restoration or completion of the Mortgaged
Property or any portion thereof, agreeing upon a date for delivery of possession
of the Mortgaged Property or their respective portions thereof, to permit time
which is sufficient in the judgment of the Agent for such repair or restoration
and approving the plans and specifications for such repair or restoration, or
other evidence satisfactory to the Agent that none of such tenants or other
parties may terminate their Leases as a result of such casualty or as a result
of having a right to approve the plans and specifications for such repair or
restoration (it being agreed that the foregoing percentage of seventy-five
percent (75%) shall be determined by reference to those tenants in the aggregate
occupying or having rights to occupy not less than seventy-five percent (75%) of
the Net Rentable Area of the Building so damaged), (vi) the Agent shall
determine that such repair or reconstruction can be completed prior to the
Maturity Date, (vii) the Agent shall receive evidence reasonably satisfactory to
it that any such restoration, repair or rebuilding complies in all respects with
any and all applicable state, federal and local laws, ordinances and
regulations, including without limitation, zoning laws, ordinances and
regulations, and that all required permits, licenses and approvals relative
thereto have been or will be issued in a manner so as not to impede the progress
of restoration, and (viii) the Agent shall receive evidence reasonably
satisfactory to it that the insurer under such policies of fire or other
casualty insurance does not assert any defense to payment under such policies
against the Borrower, REA, any Guarantor or the Agent. Any excess Insurance
Proceeds shall be paid to the Borrower, or if an Event of Default has occurred
and is continuing, such proceeds shall be applied to the payment of the
Obligations, unless in either case by the terms of the applicable insurance
policy the excess proceeds are required to be returned to such insurer. In no
event shall the provisions of this Section be construed to extend the Maturity
Date or to limit in any way any right or remedy of the Agent upon the occurrence
of an Event of Default hereunder. If the Mortgaged Property is sold or the
Mortgaged Property is acquired by the Agent, all right, title and interest of
the Borrower, REA and any Guarantor in and to any insurance policies and
unearned premiums thereon and in and to the proceeds thereof resulting from loss
or damage to the Mortgaged Property prior to the sale or acquisition shall pass
to the Agent or any other successor in interest to the Borrower or purchaser of
the Mortgaged Property.

         (f) The Borrower, REA and each and Guarantor will require any general
contractor to obtain and maintain at all times during the construction of any
improvements to the Mortgaged Property the insurance required by the general
contractor's contract approved by the Agent and such other insurance as may be
reasonably required by the Agent (including, without limitation, commercial
general liability insurance, comprehensive automobile liability insurance,
all-risk contractor's equipment floater insurance, workmen's compensation
insurance and employer liability insurance). The Borrower, REA and each and
Guarantor will require its architect, engineer and any other design professional
providing design or engineering services in



                                       54
<PAGE>

connection with the construction of any improvements to the Mortgaged Property
to obtain and maintain professional liability insurance covering any claims
asserted with respect to the Mortgaged Property for such period of time as the
Agent may reasonably approve. All such insurance required by this paragraph
shall be in such amounts and form, to include such coverage and endorsements,
and to be issued by such insurers as shall be approved by the Agent, and to
contain the written agreement of the insurer to give the Agent thirty (30) days
prior written notice of cancellation, nonrenewal, modification or expiration.
The Borrower, REA and each Guarantor will provide or will cause its general
contractor or design professional to provide the Agent with certificates
evidencing such insurance upon the request of the Agent.

         (g) The Borrower, REA and the Guarantors will, and will cause each of
their respective Subsidiaries to, at their expense, procure and maintain
insurance covering the Real Estate other than the Collateral in such amounts and
against such risks and casualties as are customary for properties of similar
character and location, due regard being given to the type of improvements
thereon, their construction, location, use and occupancy.

         (h) The Borrower, REA and the Guarantors will provide to the Agent for
the benefit of the Lenders Title Policies for all of the Mortgaged Properties of
such Person. Each Title Policy shall also contain, to the extent available, a
tie-in endorsement aggregating the insurance coverage provided under all of the
policies issued by the same title insurance company relating to the Borrower,
REA and each Guarantor.

         Section 7.8 Taxes. The Borrower, REA and the Guarantors will, and will
cause their respective Subsidiaries to, duly pay and discharge, or cause to be
paid and discharged, before the same shall become overdue, all taxes,
assessments and other governmental charges imposed upon them or upon the
Mortgaged Properties or the other Real Estate, sales and activities, or any part
thereof, or upon the income or profits therefrom, provided that any such tax,
assessment, charge or levy or claim need not be paid if the validity or amount
thereof shall currently be contested in good faith by appropriate proceedings
which shall suspend the collection thereof with respect to such property,
neither such property nor any portion thereof or interest therein would be in
any danger of sale, forfeiture or loss by reason of such proceeding and the
Borrower, REA, any such Guarantor or any such Subsidiary shall have set aside on
its books adequate reserves in accordance with GAAP; and provided, further, that
forthwith upon the commencement of proceedings to foreclose any lien that may
have attached as security therefor, the Borrower, REA, any such Guarantor or any
such Subsidiary either (i) will provide a bond issued by a surety reasonably
acceptable to the Agent and sufficient to stay all such proceedings or (ii) if
no such bond is provided, will pay each such tax, assessment, charge or levy.

         Section 7.9 Inspection of Properties and Books. The Borrower, REA and
the Guarantors will, and will cause their respective Subsidiaries to, permit the
Lenders, through the Agent or any representative designated by the Agent, at the
Borrower's expense and upon reasonable prior notice to visit and inspect any of
the properties of the Borrower, REA, each Guarantor or any of their respective
Subsidiaries, to examine the books of account of the Borrower, REA, each
Guarantor and their respective Subsidiaries (and to make copies thereof and
extracts therefrom) and to discuss the affairs, finances and accounts of the
Borrower, REA, any Guarantor and their respective Subsidiaries with, and to be
advised as to the same by, their respective officers, all at



                                       55
<PAGE>

such reasonable times and intervals as the Agent or any Lender may reasonably
request. The Lenders shall use good faith efforts to coordinate such visits and
inspections so as to minimize the interference with and disruption to the normal
business operations of the Borrower, REA, the Guarantors and their respective
Subsidiaries.

         Section 7.10 Compliance with Laws, Contracts, Licenses, and Permits.
The Borrower, REA and the Guarantors will, and will cause each of their
respective Subsidiaries to, comply in all respects with (i) all applicable laws
and regulations now or hereafter in effect wherever its business is conducted,
including all Environmental Laws, (ii) the provisions of its corporate charter,
partnership agreement, limited liability company agreement or declaration of
trust, as the case may be, and other charter documents and bylaws, (iii) all
agreements and instruments in all material respects to which it is a party or by
which it or any of its properties may be bound, (iv) all applicable decrees,
orders, and judgments, and (v) all licenses and permits required by applicable
laws and regulations for the conduct of its business or the ownership, use or
operation of its properties. If any authorization, consent, approval, permit or
license from any officer, agency or instrumentality of any government shall
become necessary or required in order that the Borrower, REA, any Guarantor or
their respective Subsidiaries may fulfill any of its obligations hereunder, the
Borrower, REA, such Guarantor or such Subsidiary will immediately take or cause
to be taken all steps necessary to obtain such authorization, consent, approval,
permit or license and furnish the Agent and the Lenders with evidence thereof.

         Section 7.11 Further Assurances. The Borrower, REA and each Guarantor
will and will cause each of their respective Subsidiaries to, cooperate with the
Agent and the Lenders and execute such further instruments and documents as the
Lenders or the Agent shall reasonably request to carry out to their satisfaction
the transactions contemplated by this Agreement and the other Loan Documents.

         Section 7.12 Intentionally Omitted.

         Section 7.13 Management. (a) There shall not occur, without the prior
written consent of the Majority Lenders, any material change in any unaffiliated
third party management of the Mortgaged Properties (including, without
limitation, the hiring or termination of any unaffiliated third party property
manager).

         (b) Each of the Borrower, REA and each Guarantor shall have the right
to cause its Mortgaged Property to be managed pursuant to a Management Agreement
that (i) is with a property manager which is not an Affiliate and which has been
approved by the Agent, and (ii) contains provisions reasonably satisfactory to
the Agent, including with respect to compensation of the property manager,
subordination of management fees, termination rights and exercise by the Agent
of its remedies under the Loan Documents following an Event of Default. Neither
the Borrower, REA nor any Guarantor shall directly or indirectly enter into any
Management Agreement or similar agreement delegating to another Person which is
not an Affiliate substantial authority over the leasing, maintenance or
operation of any Mortgaged Property other than as aforesaid.

         Section 7.14 Leases of the Property. Neither the Borrower, REA nor any
Guarantor will lease all or any portion of a Mortgaged Property or amend,
supplement or otherwise modify, terminate or cancel, or accept the surrender of,
or consent to the assignment or subletting of, or grant any concessions to or
waive the performance of any obligations of any tenant, lessee or licensee
under, any now existing or future Lease without the prior written consent of the
Agent; provided, however, with respect to any Lease which covers less than the
lesser of 20,000 square feet or five percent (5%) of the aggregate Net Rentable
Area of the Mortgaged Properties, the Borrower, REA or any Guarantor may amend,
supplement or otherwise modify, terminate or cancel, or accept the surrender of,
or consent to the assignment or subletting of, or granting concessions to or
waive the performance of any obligations of any tenant, lessee or licensee under
any such Lease in the ordinary course of business consistent with sound leasing
and management practices for similar properties. The Borrower, at the Agent's
request, shall furnish the Agent with executed copies of all Leases hereafter
made. Within 30 days from the date hereof, the Borrower will submit to the Agent
a form lease for use for office properties and a form lease for industrial
properties (collectively, the "Form Lease") for the Mortgaged Properties, which
shall be reasonably satisfactory to the Agent and shall thereafter be utilized
in connection with all leasing of space at the Mortgaged Properties. Upon the
Agent's request, the Borrower, REA and each Guarantor shall make a separate and
distinct assignment to the Agent as additional security, of all Leases hereafter
made. Notwithstanding the foregoing, following the Agent's approval of the
"Leasing Parameters" (as hereinafter defined) for a Mortgaged Property, the
Borrower, REA or any Guarantor may, without the prior approval of the Agent,
enter into any Lease provided that the Lease covers less than the lesser of
20,000 square feet or five percent (5%) of the aggregate Net Rentable Area of
the Mortgaged Properties, is a bona fide arm's length lease entered into in the
ordinary course of business with a party which is not an Affiliate of the
Borrower, REA or any Guarantor, falls within the Leasing Parameters and is on
the Form Lease (without material modification or addition). Any Lease submitted
to the Agent for approval shall be deemed approved by the Agent unless the Agent
expressly disapproves the same by written notice delivered to the Borrower
(which shall state the reasons for disapproval) within five (5) Business Days
after the date of the delivery of such Lease to the Agent for approval and all
other information reasonably requested by the Agent in order to make such
determination. As used herein, "Leasing Parameters" means leasing parameters for
a Mortgaged Property approved by the Agent. Leasing Parameters shall include,
without limitation, the minimum and maximum term, the minimum rent, tax and
operating stops, tenant standard improvements, tenant allowances and other
tenant inducements and leasing commissions, and shall be approved by the Agent
prior to the commencement of each calendar year during the term of the Notes.
The Agent agrees to provide a Subordination, Attornment and Nondisturbance
Agreement for the tenant under any Lease that covers more than the lesser of
20,000 square feet or five (5%) of the aggregate Net Rentable Area of the
Mortgaged Properties as requested by the Borrower, provided that (a) such tenant
is not an Affiliate of the Borrower, REA or any Guarantor, (b) the Lease is on
the Form Lease (without modifications or additions), (c) the Lease falls within
the Leasing Parameters, and (d) the terms of the Subordination, Attornment and
Nondisturbance Agreement are otherwise acceptable to the Agent. The Agent shall
provide a Subordination, Attornment and Nondisturbance Agreement with respect to
each other Lease that is approved by the Agent provided that the terms of the
Subordination, Attornment and Nondisturbance Agreement are acceptable to the
Agent.

of the Agent, none of the Mortgaged Properties shall be owned or operated by the
Borrower, REA or any Guarantor under any registered or protected trademark,
tradename, servicemark or logo. Without limiting the foregoing, the Agent may
condition its consent to the use of any of the foregoing upon the granting to
the Agent for the benefit of the Lenders of a perfected first priority security
interest therein.

         Section 7.17 Ownership of Real Estate. All Real Estate and all
interests (whether direct or indirect) of REA, the Borrower, the Guarantors and

<PAGE>

restrictions contained in Section 8.3, the Borrower shall be permitted to own or

that: (i) REA will at all times (a) be the sole general partner of the Borrower,
(b)own the largest percentage interest of any partner in the Borrower which
percentage will be sufficient to permit the accounts of the Borrower and REA to
be determined on a consolidated basis in accordance with GAAP and (c) be
responsible for making all day-to-day operational and management decisions to be
made by the Borrower in the conduct of its business and (ii) each Guarantor will
be and remain a wholly owned subsidiary of the Borrower, except for Virginia
Street Associates Limited Partnership ("Virginia"), as to which a 0.1% limited
partnership interest may continue to be owned by Gail Mulvihill.

         Section 7.20    Intentionally Omitted.

         Section 7.21 REIT Status. Subject to the terms of Section 8.7, REA

removal of such lien by bonding or deposit with the country clerk or otherwise
or, at the Agent's option, promptly obtain insurance against, any such lien

any other item which may cause any such lien to be filed against any Mortgaged
Property or Collateral. The Borrower shall fully preserve the liens and the
priority of the Mortgages without cost or expense to the Agent.

         (b) If the Borrower fails to promptly discharge or remove any such lien
described in paragraph (a) of this Section 7.23 within thirty (30) days after
the receipt of written notice thereof, then the Agent may, but shall not be
required to, procure the release and discharge of such lien, and any judgment or

Collateral or any portion thereof, the Agent may, at the expense of the
Borrower, obtain an updated title and/or lien search regarding such Mortgaged
Property or Collateral; provided that if no such lien not otherwise permitted

quarter and (b) the establishment of reasonable reserves for the payment of
Operating Expenses not paid on at least a quarterly basis and capital

<PAGE>

         Lenders may engage their own Environmental Engineer to review the
         environmental assessments and the compliance with the covenants
         contained herein. Notwithstanding the foregoing, if any Release or
         disposal of Hazardous Substances shall occur or shall have occurred on
         the Real Estate (except any such Release or disposal occurring prior to
         the acquisition or leasing of such Real Estate by the Borrower, REA, a
         Guarantor or any such Subsidiary and disclosed in an environmental
         assessment delivered to the Agent prior to the inclusion of such Real
         Estate in the Collateral) and such Real Estate is a Mortgaged Property,
         the Agent shall have the right to require that the Borrower, in
         compliance with Section 9, provide to the Agent a substitute Mortgaged
         Property which is Eligible Real Estate within ninety (90) days of
         demand by the Agent in accordance with Section 5.3 or obtain the
         release of such Mortgaged Property pursuant to Section 5.4.

         At any time after an Event of Default shall have occurred hereunder,

Agent or the Majority Lenders shall have reasonable grounds to believe that a
Release or threatened Release of Hazardous Substances may have occurred,
relating to any Real Estate, or that any of the Real Estate is not in compliance
with Environmental Laws, the Agent may at its election (and will at the request
of the Majority Lenders) obtain such environmental assessments of such Real
Estate prepared by an Environmental Engineer as may be necessary or advisable
for the purpose of evaluating or confirming (i) whether any Hazardous Substances
are present in the soil or water at or adjacent to such Real Estate and (ii)
whether the use and operation of such Mortgaged Property comply with all
Environmental Laws. Environmental assessments may include detailed visual
inspections of such Real Estate including, without limitation, any and all
storage areas, storage tanks, drains, dry wells and leaching areas, and the
taking of soil samples, as well as such other investigations or analyses as are
necessary or appropriate for a complete determination of the compliance of such
Real Estate and the use and operation thereof with all applicable Environmental
Laws. All such environmental assessments shall be at the sole cost and expense
of the Borrower; except for those assessments required by the Agent at a time
when an Event of Default does not exist and which fail to reveal the existence
of a Release of Hazardous Substance and/or that the Real Estate is not in
compliance with Environmental Laws, which assessments shall be at the sole cost
and expense of the Lenders.

         Section 8.7 Distributions. Neither the Borrower, REA or the
Guarantors will, or will permit their respective Subsidiaries to, make any
Distributions which would violate any of the following covenants:

         its partners or shareholders the amount of which, when added to the
         amount of all other Distributions paid by it in the same fiscal quarter
         and the three immediately preceding fiscal quarters, would exceed one
         hundred percent (100%) of its Funds from Operations for such period;

                  (b) In the event that an Event of Default shall have occurred
         and be continuing, neither the Borrower nor REA shall make any
         Distributions other than the minimum Distributions required under the
         Code to maintain the REIT Status



                                       66
<PAGE>

         of REA, as evidenced by a certification of an authorized representative
         of each of the Borrower and REA containing calculations in reasonable
         detail satisfactory in form and substance to the Agent; and

                  (c) In the event that an Event of Default shall have occurred
         and be continuing and the maturity of the Obligations has been
         accelerated, neither the Borrower, REA, the Guarantors nor any of their
         respective Subsidiaries shall make any Distributions whatsoever, either

development of properties without the prior written consent of the Majority
Lenders in their sole discretion; provided that without the consent of the
Majority Lenders the Borrower, REA, the Guarantors or their respective
Subsidiaries may engage in the development of any number of properties to be
used principally for office and/or industrial purposes provided that the
aggregate cost (on a fully developed basis) of acquisition and development of
properties Under Development at any time shall not exceed twenty percent (20%)
of the Consolidated Total Assets of REA. Each of the Borrower, REA and the
Guarantors will, and will cause each of its respective Subsidiaries to, at all
times that it is engaging in any development as provided herein, maintain
available sources of capital equal to the total cost to acquire and complete
such developments and to purchase such properties, which sources of capital
shall be acceptable to the Agent in its reasonable discretion. Amounts available
to be disbursed for such purposes pursuant to this Agreement may be considered
as a source of capital for the purposes of this Section 8.9.

         Section 8.10 Restriction on Prepayment of Indebtedness. Neither the
Borrower, REA or the Guarantors will, or will permit their respective
Subsidiaries to, prepay after the occurrence of any Event of Default the
principal amount, in whole or in part, of any Indebtedness other than the
Obligations; provided, that this Section 8.10 shall not prohibit the prepayment
of Indebtedness which is financed solely from the proceeds of a new loan which
would otherwise be permitted by the terms of Section 8.1.

        Section 8.11 Zoning and Contract Changes and Compliance. Neither the
Borrower, REA nor any Guarantor shall initiate or consent to any zoning
reclassification of any of its Mortgaged Property or seek any variance under any

<PAGE>

         under any zoning ordinance or any other applicable land use law, rule
         or regulation. Neither the Borrower, REA, nor the Guarantors shall
         initiate or consent to any change in any laws, requirements of
         governmental authorities or obligations created by private contracts
         and Leases which now or hereafter may materially adversely affect the
         ownership, occupancy, use or operation of any Mortgaged Property.

         Section 8.12 Intentionally Omitted.

Borrower shall notify the Agent in writing as to whether or not it will attempt
to cure such Default by providing additional Collateral consisting of Potential
Collateral and/or reducing the outstanding principal amount of Loans made to it.
Any such notice (the "Cure Proposal Notice") from the Borrower to the Agent
shall describe in detail the cure which the Borrower proposes to make. In the
event that the Agent does not receive the Cure Proposal Notice from the Borrower
within such five (5) Business Day period, the Borrower's cure period shall end
and the Default under Section 12.1 A. (c) shall immediately become an Event of
Default without any further notice from or other action by the Agent or the
Lenders. In the event that the Agent receives the Cure Proposal Notice from the
Borrower within such five (5) Business Day period, the Agent shall promptly
deliver the same to the Lenders and the actions proposed to be taken by the
Borrower as specified therein shall be completed not later than fifteen (15)
days following the date on which the Borrower is notified by the Agent that the
Majority Lenders have approved the Borrower's proposed actions (or within thirty
(30) days in the event that the Borrower's proposed actions include the Borrower
providing additional Collateral consisting of Potential Collateral). Within five
(5) Business Days after their receipt of the Cure Proposal Notice, the Agent
shall advise the Borrower as to whether or not the Majority Lenders approve the
Borrower's proposed actions based on their good faith business judgment as to
whether the actions proposed by the Borrower are sufficient to cure the Default
under Section 12.1 A. (c) without the creation of any other Default. In the
event that the Agent notifies the Borrower of the disapproval by the Majority
Lenders of the Borrower's proposed actions based on the determination by the
Majority Lenders that in their good faith business judgment that the actions
proposed by the Borrower are insufficient to so cure such Default, the Borrower
may, within three (3) Business Days following its receipt of such notice, submit
to the Agent an alternative cure proposal or evidence establishing that the
Borrower's original cure proposal was so sufficient. Any such submission by the
Borrower shall be in writing and shall describe in detail the alternative
actions which the Borrower proposes to take or the evidence establishing that
the Borrower's original cure proposal was so sufficient. In the event that the
Agent does not receive such submission within such three (3) Business Day
period, the Borrower's cure period shall end and the Default under Section 12.1
A. (c) shall immediately become an Event of Default



                                       75
<PAGE>


without any further notice from or other action by the Agent or the Lenders. In
the event that the Agent receives such submission from the Borrower within such
three (3) Business Day period, the Agent shall promptly deliver the same to the
Lenders and the Agent shall, within five (5) Business Days following their
receipt of such submission, advise the Borrower as to whether in the Majority
Lenders' good faith business judgment such alternative cure proposal is
sufficient to cure such Default without the creation of any other Default
hereunder or the Borrower's original cure proposal is so sufficient. In the
event that the Majority Lenders determine that the original or alternative cure
proposal is so sufficient, the actions so approved by the Majority Lenders to be
taken by the Borrower shall be completed not later than fifteen (15) days
following the date on which the Borrower is notified by the Agent that the
Majority Lenders have approved such original or alternative proposal (or within
thirty (30) days in the event that the approved actions include the Borrower
providing additional Collateral consisting of Potential Collateral). In the
event that the Agent notifies the Borrower that the Majority Lenders have
determined that the original or alternative cure proposal is not so sufficient,
the Borrower's cure period shall end and the Default under Section 12.1 A. (c)
shall immediately become an Event of Default without any further notice from or
other actions by the Agent or the Lenders. During any period that a Default
exists under Section 12.1 A. (c), the Lenders shall have no obligation to make
any further Loans hereunder.

                  (b) In the event that the Borrower shall elect under
subsection 12.1B(a) to provide additional Collateral consisting of Potential
Collateral, the Real Estate to be added to the Collateral shall be Eligible Real
Estate and on or prior to the expiration of the 30-day period referred to in
subclause (a) above each of the Eligible Real Estate Qualification Documents
shall have been completed at the Borrower's expense and provided to the Agent
for the benefit of the Lenders.

                  (c) Within five (5) Business Days following its receipt of
notice from the Agent that a Default has occurred under Section 12.1A(f) with
respect to any representation and warranty to Mortgaged Property (including,
without limitation, the representations and warranties contained in Section 6.20
and Section 6.24), the Borrower shall notify the Agent in writing as to whether
or not it will attempt to cure such Default by substituting for such Mortgaged
Property additional Collateral consisting of Potential Collateral. The Cure
Proposal Notice from the Borrower to the Agent shall describe in detail the cure
which the Borrower proposes to make. In the event that the Agent does not
receive the Cure Proposal Notice from the Borrower within such five (5) Business
Day period, the Borrower's Cure period shall end and the Default under Section
12.1 A. (f) shall immediately become an Event of Default without any further
notice from or other action by the Agent or the Lenders. In the event that the
Agent receives the Cure Proposal Notice from the Borrower within such five (5)
Business Day period, the Agent shall promptly deliver the same to the Lenders
and the actions proposed to be taken by the Borrower as specified therein shall
be completed not later than thirty (30) days following the date on which the
Borrower is notified by the Agent that the Majority Lenders have approved the
Borrower's proposed actions. Within five (5) Business Days after their receipt
of the Cure Proposal Notice, the Agent shall advise the Borrower as to whether
or not the Majority Lenders approve the Borrower's proposed actions based on
their good faith business judgment as to whether the actions proposed by the
Borrower are sufficient to cure the Default under Section 12.1 A. (f) without
the creation of any other Default. In the event that the Agent notifies the
Borrower of the disapproval by the Majority Lenders of the



                                       76
<PAGE>


Borrower's proposed actions based on the determination by the Majority Lenders
that in their good faith business judgment the actions proposed by the Borrower
are insufficient to so cure such Default, the Borrower may, within three (3)
Business Days following its receipt of such notice, submit to the Agent an
alternative cure proposal or evidence establishing that the Borrower's original
cure proposal was so sufficient. Any such submission by the Borrower shall be in
writing and shall describe in detail the alternative actions which the Borrower
proposes to take or the evidence establishing that the Borrower's original cure
proposal was so sufficient. In the event that the Agent does not receive such
submission within such three (3) Business Day period, the Borrower's cure period
shall end and the Default under Section 12.1 A. (f) shall immediately become an
Event of Default without any further notice from or other action by the Agent or
the Lenders. In the event that the Agent receives such submission from the
Borrower within such three (3) Business Day period, the Agent shall promptly
deliver the same to the Lenders and the Agent shall, within five (5) Business
Days following their receipt of such submission, advise the Borrower as to
whether in the Majority Lenders' good faith business judgment such alternative
cure proposal is sufficient to cure such Default without the creation of any
other Default hereunder or the Borrower's original cure proposal is so
sufficient. In the event that the Majority Lenders determine that the original
or alternative cure proposal is so sufficient, the actions so approved by the
Majority Lenders to be taken by the Borrower shall be completed not later than
thirty (30) days following the date on which the Borrower is notified by the
Agent that the Majority Lenders have approved such original or alternative cure
proposal. In the event that the Agent notifies the Borrower that the Majority
Lenders have determined that the original or alternative cure proposal is not so
sufficient, the Borrower's cure period shall end and the Default under Section
12.1 A. (f) shall immediately become an Event of Default without any further
notice from or other actions by the Agent or the Lenders. During any period that
a Default exists under Section 12.1A. (f), the Lenders shall have no obligation
to make any further Loans hereunder.

         Section 12.2 Termination of Commitments. If any one or more Events of
Default specified in Section 12.1A.(h), Section 12.1A.(i) or Section 12.1A.(j)
shall occur, then immediately and without any action on the part of the Agent or
any Lender any unused portion of the credit hereunder shall terminate and the
Lenders shall be relieved of all obligations to make Loans to the Borrower. If
any other Event of Default shall have occurred, the Agent, upon the election of
the Majority Lenders, shall by notice to the Borrower terminate the obligation
to make Loans to the Borrower. No termination under this Section 12.2 shall
relieve the Borrower of its obligations to the Lenders arising under this
Agreement or the other Loan Documents.

         Section 12.3 Remedies. In case any one or more Events of Default shall
have occurred and be continuing, and whether or not the Lenders shall have
accelerated the maturity of the Loans pursuant to Section 12.1A., the Agent on
behalf of the Lenders may, with the consent of the Majority Lenders but not
otherwise, proceed to protect and enforce their rights and remedies under this
Agreement, the Notes and/or any of the other Loan Documents by suit in equity,
action at law or other appropriate proceeding, including to the full extent
permitted by applicable law the specific performance of any covenant or
agreement contained in this Agreement and the other Loan Documents, the
obtaining of the ex parte appointment of a receiver, and, if any amount shall
have become due, by declaration or otherwise, the enforcement of the payment
thereof. No remedy herein conferred upon the Agent or the holder of any Note is
intended to be exclusive of any



                                       77
<PAGE>


other remedy and each and every remedy shall be cumulative and shall be in
addition to every other remedy given hereunder or now or hereafter existing at
law or in equity or by statute or any other provision of law. In the event that
all or any portion of the Obligations is collected by or through an
attorney-at-law, the Borrower shall pay all costs of collection including, but
not limited to, reasonable attorney's fees.

         Section 12.4 Distribution of Collateral Proceeds. In the event that,
following the occurrence and during the continuance of any Event of Default, any
monies are received in connection with the enforcement of any of the Security
Documents, or otherwise with respect to the realization upon any of the
Collateral, such monies shall be distributed for application as follows:

                  (a) First, to the payment of, or (as the case may be) the
         reimbursement of the Agent for or in respect of, all reasonable costs,
         expenses, disbursements and losses which shall have been paid, incurred
         or sustained by the Agent to protect or preserve the Collateral or in
         connection with the collection of such monies by the Agent, for the
         exercise, protection or enforcement by the Agent of all or any of the
         rights, remedies, powers and privileges of the Agent or the Lenders
         under this Agreement or any of the other Loan Documents or in respect
         of the Collateral or in support of any provision of adequate indemnity
         to the Agent against any taxes or liens which by law shall have, or may
         have, priority over the rights of the Agent or the Lenders to such
         monies;

                  (b) Second, to all other Obligations in such order or
         preference as the Majority Lenders shall determine; provided, that (i)
         distributions in respect of such other Obligations shall include, on a
         pari passu basis, the Agent's fee payable pursuant to Section 4.3; (ii)
         in the event that any Lender shall have wrongfully failed or refused to
         make an advance under Section 2.7 and such failure or refusal shall be
         continuing, advances made by other Lenders during the pendency of such
         failure or refusal shall be entitled to be repaid as to principal and
         accrued interest in priority to the other Obligations described in this
         subsection (b), and (iii) except as otherwise provided in clause (ii),
         Obligations owing to the Lenders with respect to each type of
         Obligation such as interest, principal, fees and expenses shall be made
         among the Lenders pro rata; and provided, further that the Majority
         Lenders may in their discretion make proper allowance to take into
         account any Obligations not then due and payable; and

                  (c) Third, the excess, if any, shall be returned to the
         Borrower or to such other Persons as are entitled thereto.

         Section 13 SETOFF.

         Regardless of the adequacy of any Collateral, during the continuance of
any Event of Default, any deposits (general or specific, time or demand,
provisional or final, regardless of currency, maturity, or the branch where such
deposits are held) or other sums credited by or due from any Lender to the
Borrower, REA or the Guarantors and any securities or other property of the
Borrower , REA or the Guarantors in the possession of such Lender may be applied
to or set



                                       78
<PAGE>


off against the payment of Obligations and any and all other liabilities,
direct, or indirect, absolute or contingent, due or to become due, now existing
or hereafter arising, of the Borrower, REA or the Guarantors to such Lender.
Each of the Lenders agrees with each other Lender that if such Lender shall
receive from the Borrower, REA or the Guarantors, whether by voluntary payment,
exercise of the right of setoff, or otherwise, and shall retain and apply to the
payment of the Note or Notes held by such Lender any amount in excess of its
ratable portion of the payments received by all of the Lenders with respect to
the Notes held by all of the Lenders, such Lender will make such disposition and
arrangements with the other Lenders with respect to such excess, either by way
of distribution, pro tanto assignment of claims, subrogation or otherwise as
shall result in each Lender receiving in respect of the Notes held by it its
proportionate payment as contemplated by this Agreement; provided that if all or
any part of such excess payment is thereafter recovered from such Lender, such
disposition and arrangements shall be rescinded and the amount restored to the
extent of such recovery, but without interest.

         Section 14 THE AGENT.

         Section 14.1 Authorization. The Agent is authorized to take such action
on behalf of each of the Lenders and to exercise all such powers as are
hereunder and under any of the other Loan Documents and any related documents
delegated to the Agent, together with such powers as are reasonably incident
thereto, provided that no duties or responsibilities not expressly assumed
herein or therein shall be implied to have been assumed by the Agent. The
obligations of the Agent hereunder are primarily administrative in nature, and
nothing contained in this Agreement or any of the other Loan Documents shall be
construed to constitute the Agent as a trustee for any Lender or to create an
agency or fiduciary relationship. The Borrower and any other Person shall be
entitled to conclusively rely on a statement from the Agent that it has the
authority to act for and bind the Lenders pursuant to this Agreement and the
other Loan Documents.

         Section 14.2 Employees and Agents. The Agent may exercise its powers
and execute its duties by or through employees or agents and shall be entitled
to take, and to rely on, advice of counsel concerning all matters pertaining to
its rights and duties under this Agreement and the other Loan Documents. The
Agent may utilize the services of such Persons as the Agent may reasonably
determine, and all reasonable fees and expenses of any such Persons shall be
paid by the Borrower.

         Section 14.3 No Liability. Neither the Agent nor any of its
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent, or employee thereof, shall be liable to any
of the Lenders for any waiver, consent or approval given or any action taken, or
omitted to be taken, in good faith by it or them hereunder or under any of the
other Loan Documents, or in connection herewith or therewith, or be responsible
for the consequences of any oversight or error of judgment whatsoever, except
that the Agent or such other Person, as the case may be, shall be liable for
losses due to its willful misconduct or gross negligence.

         Section 14.4 No Representations. The Agent shall not be responsible for
the execution or validity or enforceability of this Agreement, the Notes, any of
the other Loan Documents or any instrument at any time constituting, or intended
to constitute, collateral security for the Notes, or for the value of any such
collateral security or for the validity, enforceability or collectibility of



                                       79
<PAGE>


any amounts owing with respect to the Notes, or for any recitals or statements,
warranties or representations made herein or in any of the other Loan Documents
or in any certificate or instrument hereafter furnished to it by or on behalf of
the Borrower, REA, the Guarantors or any of their respective Subsidiaries, or be
bound to ascertain or inquire as to the performance or observance of any of the
terms, conditions, covenants or agreements herein or in any of the other Loan
Documents. The Agent shall not be bound to ascertain whether any notice,
consent, waiver or request delivered to it by the Borrower, REA, the Guarantors
or any holder of any of the Notes shall have been duly authorized or is true,
accurate and complete. The Agent has not made nor does it now make any
representations or warranties, express or implied, nor does it assume any
liability to the Lenders, with respect to the creditworthiness or financial
condition of the Borrower, REA, the Guarantors, or any of their respective
Subsidiaries, or the value of the Collateral or any other assets of the
Borrower, REA or the Guarantors. Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender, and based
upon such information and documents as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent or
any other Lender, based upon such information and documents as it deems
appropriate at the time, continue to make its own credit analysis and decisions
in taking or not taking action under this Agreement and the other Loan
Documents.

         Section 14.5 Payments.

         (a) A payment by the Borrower, REA or any Guarantor to the Agent
hereunder or under any of the other Loan Documents for the account of any Lender
shall constitute a payment to such Lender. The Agent agrees to distribute to
each Lender not later than one Business Day after the Agent's receipt of good
funds, determined in accordance with the Agent's customary practices, such
Lender's pro rata share of payments received by the Agent for the account of the
Lenders except as otherwise expressly provided herein or in any of the other
Loan Documents.

         (b) If in the opinion of the Agent the distribution of any amount
received by it in such capacity hereunder, under the Notes or under any of the
other Loan Documents might involve it in liability, it may refrain from making
distribution until its right to make distribution shall have been adjudicated by
a court of competent jurisdiction. If a court of competent jurisdiction shall
adjudge that any amount received and distributed by the Agent is to be repaid,
each Person to whom any such distribution shall have been made shall either
repay to the Agent its proportionate share of the amount so adjudged to be
repaid or shall pay over the same in such manner and to such Persons as shall be
determined by such court.

         (c) Notwithstanding anything to the contrary contained in this
Agreement or any of the other Loan Documents, any Lender that fails (i) to make
available to the Agent its pro rata share of any Loan or (ii) to comply with the
provisions of Section 13 with respect to making dispositions and arrangements
with the other Lenders, where such Lender's share of any payment received,
whether by setoff or otherwise, is in excess of its pro rata share of such
payments due and payable to all of the Lenders, in each case as, when and to the
full extent required by the provisions of this Agreement, shall be deemed
delinquent (a "Delinquent Lender") and shall be deemed a Delinquent Lender until
such time as such delinquency is satisfied. A Delinquent Lender shall be deemed
to have assigned any and all payments due to it from the Borrower, REA



                                       80
<PAGE>


or the Guarantors, whether on account of outstanding Loans, interest, fees or
otherwise, to the remaining nondelinquent Lenders for application to, and
reduction of, their respective pro rata shares of all outstanding Loans. The
Delinquent Lender hereby authorizes the Agent to distribute such payments to the
nondelinquent Lenders in proportion to their respective pro rata shares of all
outstanding Loans. A Delinquent Lender shall be deemed to have satisfied in full
a delinquency when and if, as a result of application of the assigned payments
to all outstanding Loans of the nondelinquent Lenders or as a result of other
payments by the Delinquent Lenders to the nondelinquent Lenders, the Lenders'
respective pro rata shares of all outstanding Loans have returned to those in
effect immediately prior to such delinquency and without giving effect to the
nonpayment causing such delinquency.

         Section 14.6 Holders of Notes. Subject to the terms of Section 18, the
Agent may deem and treat the payee of any Note as the absolute owner or
purchaser thereof for all purposes hereof until it shall have been furnished in
writing with a different name by such payee or by a subsequent holder, assignee
or transferee.

         Section 14.7 Indemnity. The Lenders ratably agree hereby to indemnify
and hold harmless the Agent from and against any and all claims, actions and
suits (whether groundless or otherwise), losses, damages, costs, expenses
(including any expenses for which the Agent has not been reimbursed by the
Borrower as required by Section 15), and liabilities of every nature and
character arising out of or related to this Agreement, the Notes, or any of the
other Loan Documents or the transactions contemplated or evidenced hereby or
thereby, or the Agent's actions taken hereunder or thereunder, except to the
extent that any of the same shall be directly caused by the Agent's willful
misconduct or gross negligence.

         Section 14.8 Agent as Lender. In its individual capacity, BankBoston
shall have the same obligations and the same rights, powers and privileges in
respect to its Commitment and the Loans made by it, and as the holder of any of
the Notes as it would have were it not also the Agent.

         Section 14.9 Resignation. The Agent may resign at any time by giving 60
days' prior written notice thereof to the Lenders and the Borrower. Upon any
such resignation, the Majority Lenders (and so long as no Default or Event of
Default exists hereunder, after consultation with the Borrower) shall have the
right to appoint as a successor Agent any Lender or any financial institution
whose senior debt obligations are rated not less than "A" or its equivalent by
Moody's Investors Service, Inc. or not less than "A" or its equivalent by
Standard & Poor's corporation and which has a net worth of not less than
$500,000,000. Unless a Default or Event of Default shall have occurred and be
continuing, such successor Agent shall be reasonably acceptable to the Borrower.
If no successor Agent shall have been so appointed by the Majority Lenders and
shall have accepted such appointment within 30 days after the retiring Agent's
giving of notice of resignation, then the retiring Agent may, on behalf of the
Lenders, appoint a successor Agent, which shall be any Lender or any financial
institution whose senior debt obligations are rated not less than "A" or its
equivalent by Moody's Investors Service, Inc. or not less than "A" or its
equivalent by Standard & Poor's Corporation and which has a net worth of not
less than $500,000,000. Upon the acceptance of any appointment as Agent
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights,



                                       81
<PAGE>


powers, privileges and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations hereunder as Agent. After
any retiring Agent's resignation, the provisions of this Agreement and the other
Loan Documents shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Agent.

         Section 14.10 Duties in the Case of Enforcement. In case one or more
Events of Default have occurred and shall be continuing, and whether or not
acceleration of the Obligations shall have occurred, the Agent shall, if (a) so
requested by the Majority Lenders and (b) the Lenders have provided to the Agent
such additional indemnities and assurances against expenses and liabilities as
the Agent may reasonably request, proceed to enforce the provisions of the
Security Documents authorizing the sale or other disposition of all or any part
of the Collateral and exercise all or any such other legal and equitable and
other rights or remedies as it may have in respect of such Collateral. The
Majority Lenders may direct the Agent in writing as to the method and the extent
of any such sale or other disposition, the Lenders hereby agreeing to indemnify
and hold the Agent harmless from all liabilities incurred in respect of all
actions taken or omitted in accordance with such directions.

         Section 15 EXPENSES.

         The Borrower agrees to pay (a) the reasonable costs of reproducing this
Agreement, the other Loan Documents and the other agreements and instruments
mentioned herein, (b) any taxes (including any interest and penalties in respect
thereto) payable by the Agent or any of the Lenders (other than taxes based upon
the Agent's or any Lender's gross or net income, except that the Agent and the
Lenders shall be entitled to indemnification for any and all amounts paid by
them in respect of taxes based on income or other taxes assessed by any State in
which Mortgaged Property or other Collateral is located, such indemnification to
be limited to taxes due solely on account of the granting of Collateral under
the Security Documents and to be net of any credit allowed to the indemnified

by such indemnified party), including any recording, mortgage, documentary or
intangibles taxes in connection with the Mortgages and other Loan Documents, or

and disbursements of the counsel to the Agent and any local counsel to the Agent

or waivers hereto or hereunder, (d) all other reasonable out of pocket fees,
expenses and disbursements of the Agent actually incurred by the Agent in

rights under any of the Loan Documents against the Borrower, REA or the
Guarantors or the administration thereof after the occurrence of a Default or
Event of Default and (ii) any litigation, proceeding or dispute whether arising
hereunder or otherwise, in any way related to the Agent's or any of the Lenders'
relationship with the Borrower, REA or the Guarantors, (f) all reasonable fees,
expenses and disbursements of any Lender or the Agent incurred in connection
with UCC searches, UCC filings, title rundowns, title searches or mortgage

termination of the obligations of the Lenders hereunder.

         Section 16 INDEMNIFICATION.

         The Borrower agrees to indemnify and hold harmless the Agent and the
Lenders and each director, officer, employee, agent and Person who controls the
Agent or any Lender from and against any and all claims, actions and suits,
whether groundless or otherwise, and from and against any and all liabilities,

Mortgaged Property, in each case including, without limitation, the reasonable
fees and disbursements of counsel incurred in connection with any such
investigation, litigation or other proceeding; provided, however, that the
Borrower shall not be obligated under this Section 16 to indemnify any Person
for liabilities arising from such Person's own gross negligence or willful
misconduct. In litigation, or the preparation therefor, the Lenders and the
Agent shall be entitled to select a single law firm as their own counsel and, in
addition to the foregoing indemnity, the Borrower agrees to pay promptly the
reasonable fees and expenses of such counsel. If, and to the extent that the
obligations of the Borrower under this Section 16 are unenforceable for any
reason, the Borrower hereby agrees to make the maximum contribution to the
payment in satisfaction of such obligations which is permissible under
applicable law. The provisions of this Section 16 shall survive the repayment of
the Loans and the termination of the obligations of the Lenders hereunder.

in the Notes, in any of the other Loan Documents or in any documents or other
papers delivered by or on behalf of the Borrower, REA or the Guarantors or any
of their respective Subsidiaries pursuant hereto or thereto shall be deemed to
have been relied upon by the Lenders and the Agent, notwithstanding any
investigation heretofore or hereafter made by any of them, and shall survive the
making by the Lenders of any of the Loans, as herein contemplated, and shall
continue in full force and effect so long as any amount due under this Agreement
or the Notes or any of the other Loan Documents remains outstanding or any
Lender has any obligation to make any Loans. The indemnification obligations of
the Borrower provided herein and in the other Loan Documents shall survive the

         Section 18 ASSIGNMENT AND PARTICIPATION.

         Section 18.1 Conditions to Assignment by Lenders. Except as provided

portion of its interests, rights and obligations under this Agreement (including
all or a portion of its Commitment Percentage and Commitment and the same
portion of the Loans at the time owing to it and the Notes held by it); provided
that (a) the Agent and, so long as no Default or Event of Default exists
hereunder, the Borrower shall have each given its prior written consent to such
assignment, which consent shall not be unreasonably withheld or delayed
(provided that such consent shall not be required for any assignment to another
Lender, to a lender which is and remains under common control with the assigning
Lender or to a wholly-owned Subsidiary of such Lender, provided that such
assignee shall remain a wholly-owned Subsidiary of such Lender), (b) each such
assignment shall be of a constant, and not a varying, percentage of all the
assigning Lender's rights and obligations under this Agreement, (c) the parties
to such assignment shall execute and deliver to the Agent, for recording in the
Register (as hereinafter defined), a notice of such assignment, (d) in no event
shall any voting, consent or approval rights of a Lender be assigned to any
Person controlling, controlled by or under common control with, or which is not
otherwise free from influence or control by, the Borrower or REA, which rights
shall instead be allocated pro rata among the other remaining Lenders (e) such
assignee shall have a net worth as of the date of such assignment of not less
than $200,000,000, (f) such assignee shall acquire an interest in the Loans of
not less than $5,000,000 (or if less the remaining Loans of the assignor), and
(g) such assignment shall be of an equal percentage of such assignee's
Commitment Percentage. In addition, each Lender shall attempt (but shall not be
obligated) to assign its interests, rights and obligations under this Agreement
to a Person who shall be able to deliver to the Borrower the documentation
described in Section 4.4(c) evidencing no need to withhold or deduct amounts
from payments to be made such Person hereunder. Upon execution, delivery,
acceptance and recording of such notice of assignment, (i) the assignee
thereunder shall be a party hereto and all other Loan Documents executed by the
Lenders and have the rights and obligations of a Lender hereunder, (ii) the



                                       84
<PAGE>


assigning Lender shall, upon payment to the Agent of the registration fee
referred to in Section 18.2, be released from its obligations under this
Agreement arising after the effective date of such assignment with respect to
the assigned portion of its interests, rights and obligations under this
Agreement, and (iii) the Agent may unilaterally amend Schedule 1 to reflect such
assignment. In connection with each assignment, the assignee shall represent and
warrant to the Agent, the assignor and each other Lender as to whether such
assignee is controlling, controlled by, under common Control with or is not
otherwise free from influence or control by, the Borrower or REA.

         Section 18.2 Register. The Agent shall maintain on behalf of the
Borrower a copy of each assignment delivered to it and a register or similar
list (the "Register") for the recordation of the names and addresses of the
Lenders and the Commitment Percentages of and principal amount of the Loans
owing to the Lenders from time to time. The entries in the Register shall be
conclusive, in the absence of manifest error, and the Borrower, REA, the
Guarantors, the Agent and the Lenders may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes of this
Agreement. The Register shall be available for inspection by the Borrower and
the Lenders at any reasonable time and from time to time upon reasonable prior
notice. Upon each such recordation, the assigning Lender agrees to pay to the
Agent a registration fee in the sum of $2,000.

         Section 18.3 New Notes. Upon its receipt of an assignment executed by
the parties to such assignment, the Agent shall (a) record the information
contained therein in the Register, and (b) give prompt notice thereof to the
Borrower and the Lenders (other than the assigning Lender). The assigning Lender
shall deliver to the Agent each Note which is the subject of an assignment.
Within five (5) Business Days after receipt of confirmation from the Agent that
it has received each Note subject to such assignment, the Borrower, at its own
expense, shall execute and deliver to the Agent, in exchange for each
surrendered Note, a new Note to the order of such assignee in an amount equal to
the amount assigned to such assignee pursuant to such assignment and, if the
assigning Lender has retained some portion of its obligations hereunder, a new
Note to the order of the assigning Lender in an amount equal to the amount
retained by it hereunder. Such new Notes shall provide that they are
replacements for the surrendered Notes, shall be in an aggregate principal
amount equal to the aggregate principal amount of the surrendered Notes, shall
be dated the effective date of such assignment and shall otherwise be in
substantially the form of the assigned Notes. The surrendered Notes shall be
canceled and returned to the Borrower.

         Section 18.4 Participations. Each Lender may sell participations to one
or more Lenders or other entities in all or a portion of such Lender's rights
and obligations under this Agreement and the other Loan Documents; provided that
(a) any such sale or participation shall not affect the rights and duties of the
selling Lender hereunder, (b) such participation shall not entitle such
participant to any rights or privileges under this Agreement or any Loan
Documents, including without limitation, rights granted to the Lenders under
Section 4.8, Section 4.9 and Section 4.10, (c) such participation shall not
entitle the participant to the right to approve waivers, amendments or
modifications, (provided that the Lender granting the participation interest
shall not be prohibited from granting any participant (in the participation
agreement to be entered into between the Lender and such participant) the right
to approve waivers, amendments or modifications if any such waiver, amendment or
modification would (i) extend the Maturity Date or reduce the rate or



                                       85
<PAGE>


extend the time of payment of interest on the Loans or any fees payable in
respect thereof or reduce the principal amount thereof or increase the amount of
the participant's participation over the amount thereof then in effect (it being
understood that a waiver of any Default or Event of Default or of a mandatory
reduction in the Commitments or any amendment to the Borrowing Base shall not
constitute a change in the terms of such participation, and that an increase in
any Commitment or Loan shall be permitted without the consent of any participant
if the participant's participation is not increased as a result thereof) or (ii)
constitute a consent to the assignment or transfer by the Borrower of any of its
rights or obligations under this Agreement), (d) such participant shall have no
direct rights against the Borrower, (e) such sale is effected in accordance with
all applicable laws, and (f) such participant shall not be a Person Controlling,
Controlled by or under common Control with, or which is not otherwise free from
influence or control by any of the Borrower or REA.

any portion of its interest and rights under this Agreement (including all or
any portion of its Note) to any of the twelve Federal Reserve Lenders organized
under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such
pledge or the enforcement thereof shall release the pledgor Lender from its
obligations hereunder or under any of the other Loan Documents.

         Section 18.6 No Assignment by Borrower. The Borrower shall not assign
or transfer any of its rights or obligations under this Agreement without the
prior written consent of each of the Lenders.

disclosures made in accordance with standard banking practices any Lender may
disclose information obtained by such Lender pursuant to this Agreement to

or participants hereunder. The Agent and each Lender shall otherwise use
reasonable efforts to hold any confidential information which it may receive

disclosure to (i) legal counsel, accountants and other professional advisors to
the Agent, any Lender, any assignee, participant, potential assignee or
participant, (ii) regulatory officials having jurisdiction over Agent, any
Lender or any assignee, participant, potential assignee or participant, and
(iii) as required by law or legal process or in connection with any legal
proceeding to which the Agent, any Lender or any assignee, participant,
potential assignee or participant is a party. Confidential information shall not
include any information which is or subsequently becomes publicly available, or
prior to the delivery to the Agent or the Lenders hereunder is within the
possession of such party, or is disclosed with the prior written approval of the
Borrower.

         Section 18.8 Amendments to Mortgages. Upon any such assignment or
participation, the Borrower, REA and the Guarantors shall, upon the request of

         EACH OF THE BORROWER, REA, THE GUARANTORS, THE AGENT AND THE LENDERS
HEREBY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM
ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY NOTE OR ANY OF
THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER OR

PROHIBITED BY LAW, THE BORROWER, REA, AND THE GUARANTORS HEREBY WAIVE ANY RIGHT
THEY MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY,
PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO,
ACTUAL DAMAGES. THE BORROWER, REA, AND THE GUARANTORS (A) CERTIFY THAT NO

EXPRESSLY OR OTHERWISE, THAT SUCH LENDER OR THE AGENT WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGE THAT THE

         The Lenders and their Affiliates may accept deposits from, extend
credit to and generally engage in any kind of banking, trust or other business
with the Borrower, REA, the Guarantors and their respective Subsidiaries or any
of their Affiliates regardless of the capacity of the Lender hereunder.

         Section 27 CONSENTS, AMENDMENTS, WAIVERS, ETC.

         Except as otherwise expressly provided in this Agreement, any consent
or approval required or permitted by this Agreement may be given, and any term
of this Agreement or of any other instrument related hereto or mentioned herein
may be amended, and the performance or observance by the Borrower, REA or the
Guarantors of any terms of this Agreement or such other instrument or the
continuance of any Default or Event of Default may be waived (either generally
or in a particular instance and either retroactively or prospectively) with, but
only with, the written consent of the Majority Lenders. Notwithstanding the
foregoing, none of the



                                       90
<PAGE>


following may occur without the written consent of each Lender: a change in the
rate of interest on or the term of the Notes; a change in the amount of the
Commitments of the Lenders; a forgiveness, reduction or waiver of the principal
of any unpaid Loan or any interest thereon or fee payable under the Loan
Documents; a change in the amount of any fee payable to a Lender hereunder; the
postponement of any date fixed for any payment of principal of or interest on
the Loan; an extension of the Maturity Date; a change in the manner of
distribution of any payments to the Lenders or the Agent; the release of the
Borrower, REA, any Guarantor, or any Collateral except as otherwise provided

lesser number of Lenders to approve such action. The provisions of Section 14
may not be amended without the written consent of the Agent. No waiver shall
extend to or affect any obligation not expressly waived or impair any right
consequent thereon. No course of dealing or delay or omission on the part of the
Agent or any Lender in exercising any right shall operate as a waiver thereof or
otherwise be prejudicial thereto. No notice to or demand upon any of the
Borrower, REA or the Guarantors shall entitle the Borrower, REA or any Guarantor
to other or further notice or demand in similar or other circumstances.

         Section 28 SEVERABILITY.

         The provisions of this Agreement are severable, and if any one clause
or provision hereof shall be held invalid or unenforceable in whole or in part
in any jurisdiction, then such invalidity or unenforceability shall affect only
such clause or provision, or part thereof, in such jurisdiction, and shall not
in any manner affect such clause or provision in any other jurisdiction, or any
other clause or provision of this Agreement in any jurisdiction.

         Section 29 TIME OF THE ESSENCE.

         Time is of the essence with respect to each and every covenant,
agreement and obligation of the Borrower, REA and the Guarantors under this
Agreement and the other Loan Documents.

         Section 30 NO UNWRITTEN AGREEMENTS.

         THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES
AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN
THE PARTIES.

         Section 31 REMEDIES OF THE BORROWER.

         In the event that a claim is made that the Agent has, or the Lenders
have, acted unreasonably or unreasonably delayed acting in any case where by law
or under this Agreement or the other Loan Documents, the Agent has, or the
Lenders have an obligation to act reasonably



                                       91
<PAGE>


or promptly, each of the Borrower, REA and the Guarantors agrees to the extent
permitted by law, that neither the Agent nor the Lenders shall be liable for any
monetary damages, and the sole remedy of the Borrower, REA and the Guarantors
shall be limited to commencing an action seeking injunctive relief or
declaratory judgment. In any action or proceeding to determine whether the Agent
has, or the Lenders have, acted reasonably or promptly, each of the Borrower,
REA and the Guarantors agrees to the extent permitted by law, that neither the
Agent nor the Lenders nor their respective agents shall be liable for any
monetary damages, and the sole remedies of the Borrower, REA and the Guarantors
shall be limited to commencing an action seeking injunctive relief or
declaratory judgment. The parties hereto agree that any action or proceeding to
determine whether the Agent has, or the Lenders have, acted reasonably shall be
determined by an action seeking declaratory judgment.

         Section 32 REA Guaranty

         Section 32.1 The Guaranty. In order to induce the Lenders and the Agent
to enter into this Agreement and to extend credit hereunder and in recognition
of the direct benefits to be received by REA from the proceeds of the Loans, REA
hereby agrees with the Agent and each of the Lenders as follows: REA hereby
unconditionally and irrevocably guarantees as primary obligor and not merely as
surety the full and prompt payment and performance when due, whether upon
maturity, by acceleration or otherwise, of any and all of the Obligations. If
any or all of the Obligations becomes due and payable hereunder, REA
unconditionally promises to pay such indebtedness to the Lenders or order, on
written demand, together with any and all reasonable expenses which may be
incurred by the Lenders in collecting any of the Obligations, and until paid to
the Lenders, such sums shall bear interest at the interest rate payable on
overdue amounts set forth in Section 4.12.

         Section 32.2 Bankruptcy. Additionally, REA unconditionally and
irrevocably guarantees the payment and performance of any and all of the
Obligations to the Lenders and the Agent whether or not then due or payable by
the Borrower upon the occurrence in respect of the Borrower of any of the events
specified in Section 12.1A(h), (i) or (j), and unconditionally and irrevocably
promises to pay the Obligations to the Lenders, or order, on demand, in lawful
money of the United States.

          Section 32.3 Nature of Liability. The liability of REA hereunder is
exclusive and independent of any security for or other guaranty of the
Obligations whether executed by REA, any Guarantor or by any other party, and
the liability of REA hereunder shall not be affected or impaired by (a) any
direction as to application of payment by the Borrower or by any other party, or
(b) any other continuing or other guaranty, undertaking or maximum liability of
a Guarantor or of any other party as to the Obligations or (c) any payment on or
in reduction of any such other guaranty or undertaking, or (d) any dissolution,
termination or increase, decrease or change in personnel by the Borrower, or (e)
any payment made to any Lenders on the indebtedness which such Lenders repay the
Borrower pursuant to court order in any bankruptcy, reorganization, arrangement,
moratorium or other debtor relief proceeding, and REA waives any right to the
deferral or modification of its obligations hereunder by reason of any such
proceeding.

         Section 32.4 Independent Obligation. This is a guaranty of payment and
performance and not of collection. The obligations of REA hereunder are
independent of the obligations of any



                                       92
<PAGE>


Guarantor or the Borrower, and a separate action or actions may be brought and
prosecuted against REA whether or not action is brought against any Guarantor or
the Borrower and whether or not any Guarantor or the Borrower be joined in any
such action or actions. Any payment or performance by the Borrower or other
circumstance which operates to toll any statute of limitations as to the
Borrower shall operate to toll the statute of limitations as to REA.

         Section 32.5 Authorization. REA authorizes the Agent and each of the
Lenders without notice or demand (except as shall be required by applicable
statue and cannot be waived), and without affecting or impairing its liability
hereunder, from time to time to:

                  (e) change the manner, place or terms of payment or
         performance of, and/or change or extend the time of payment or
         performance of, renew, increase, accelerate or alter, any of the
         Obligations (including any increase or decrease in the rate of interest
         thereon), any security therefor, or any liability incurred directly or
         indirectly in respect thereof, and the guaranty herein made shall apply
         to the Obligations as so changed, extended, renewed or altered;

                  (f) take and hold security for the payment and performance of
         the Obligations and sell, exchange, release, surrender, realize upon or
         otherwise deal with in any manner and in any order any property by
         whomsoever at any time pledged or mortgaged to secure, or howsoever
         securing, the Obligations or any liabilities (including any of those
         hereunder) incurred directly or indirectly in respect thereof or
         hereof, and/or any offset thereagainst;

                  (g) exercise or refrain from exercising any rights against the
         Borrower, any Guarantor or any other Person or otherwise act or refrain
         from acting;

                  (h) release or substitute one or more of the Borrower, the
         Guarantors, endorsers, and guarantors or other obligors;

                  (i) settle or compromise any of the Obligations, any security
         therefor or any liability (including any of those hereunder) incurred
         directly or indirectly in respect thereof or hereof, and may
         subordinate the payment of all or any part thereof to the payment of
         any liability (whether due or not) of the Borrower to its creditors
         other than the Lenders;

                  (j) apply any sums by whomsoever paid or howsoever realized to
         any liability or liabilities of the Borrower to the Lenders regardless
         of what liability or liabilities of the Borrower remain unpaid;

                  (k) consent to or waive any breach of, or any act, omission or
         default under, this Agreement or any of the instruments or agreements
         referred to herein, or otherwise amend, modify or supplement this
         Agreement or any of such other instruments or agreements; and/or

                  (l) take any other lawful action which would, under otherwise
         applicable principles of common law, give rise to a legal or equitable
         discharge of REA from its liabilities under this Section 32.



                                       93
<PAGE>


         Section 32.6 Partial Invalidity. No invalidity, irregularity or
unenforceability of all or any part of the Obligations or of any security
therefore shall affect, impair or be a defense to this guaranty, and this
guaranty shall be primary, absolute, irrevocable and unconditional
notwithstanding the occurrence of any event or the existence of any other
circumstances which might constitute a legal or equitable discharge of a surety
or guarantor except payment in full of the Obligations.

         Section 32.7 Continuing Obligation. This guaranty is a continuing one
and all liabilities to which it applies or may apply under the terms hereof
shall be conclusively presumed to have been created in reliance hereon. No
failure or delay on the part of the Agent or any Lender in exercising any right,
power or privilege hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
any other or further exercise thereof or the exercise thereof or the exercies of
any other right, power or privilege. The rights and remedies herein expressly
specified are cumulative and not exclusive of any rights or remedies which the
Agent or any Lender would otherwise have. No notice to or demand on REA in any
case shall entitle REA to any other or further notice or demand in similar or
other circumstances or constitute a waiver of the rights of the Agent or any
Lender to any other or further action in any circumstances without notice or
demand. It is not necessary for the Agent or any Lender to inquire into the
capacity or powers of the Borrower or the officers, directors, partners or
agents acting or purporting to act on its behalf, and any indebtedness made or
created in reliance upon the professed exercised of such powers shall be
guaranteed hereunder.

         Section 32.8 Reliance. It is not necessary for the Agent or the other
Lenders to inquire into the capacity or powers of the Borrower or any Guarantor
or the officers, directors, partners or agents acting or purporting to act on
its behalf, and any Obligations made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

         Section 32.9 Subordination. Any indebtedness of the Borrower now or
hereafter owing to REA is hereby subordinated to the Obligations and if the
Agent so requests at a time when an Event of Default exists, all such
indebtedness of the Borrower to REA shall be collected, enforced and received by
REA for the benefit of the Lenders and be paid over to the Agent on behalf of
the Lenders on account of the Obligations but without affecting or impairing in
any manner the liability of REA under the other provisions of this guaranty.
Prior to the transfer by REA of any note or negotiable instrument evidencing any
of the indebtedness of the Borrower to REA, REA shall mark such note or
negotiable instrument with a legend that the same is subject to this
subordination. Without limiting the generality of the foregoing, REA hereby
agrees with the Lenders that it will not exercise any right of subrogation which
it may at any time otherwise have as a result of this guaranty (whether
contractual, under Section 509 of the Bankruptcy Code, or otherwise) until all
Obligations have been paid in full in cash (it being understood that REA is not
waiving any right of subrogation that it may otherwise have but is only waiving
the exercise thereof as provided above).

         Section 32.10 Waiver. (a) REA waives any right (except as shall be
required by applicable law and cannot be waived) to require the Agent or the
other Lenders to (i) proceed against the Borrower, any Guarantor or any other
Person, (ii) proceed against or exhaust any security held from the Borrower, any
Guarantor or any other Person or (iii) pursue any other remedy in the Agent's or
the other Lender's power whatsoever. REA waives (except as shall be required by



                                       94
<PAGE>


applicable law and cannot be waived) any defense to its obligations under this
Section 32 based on or arising out of any defense of the Borrower, any Guarantor
or any other Person, other than payment and performance in full of the
Obligations, based on or arising out of the disability of the Borrower, any
Guarantor or any other person, or the unenforceability of the Obligations or any
part thereof from any cause, or the cessation from any cause of the liability of
the Borrower other than payment and performance in full of the Obligations. The
Agent and the other Lenders may, at their selection, foreclose on any security
held by the Agent or the other Lenders by one or more judicial or nonjudicial
sales, whether or not every aspect of any such sale is commercially reasonable
(to the extent such sale is permitted by applicable law), or exercise any other
right or remedy the Agent and the other Lenders may have against the Borrower or
any other party, or any security, without affecting or impairing in any way the
liability of REA hereunder except to the extent the Obligations have been paid
or performed. REA waives any defense arising out of any such election by the
Agent and the other Lenders, even though such election operates to impair or
extinguish any right of reimbursement or subrogation or other right or remedy of
REA against the Borrower or any other party or any security.

         (b) REA waives, except as shall be required by applicable law and
cannot be waived, all presentments, demands for performance, protests and
notices, including without limitation notices of nonperformance, notices of
protest, notices of dishonor, notices of acceptance of this guaranty, and
notices of the existence, creation of incurring of new or additional
Obligations. REA assumes all responsibility for being and keeping itself
informed of the financial condition and assets of the Borrower, and of all other
circumstances bearing upon the risk of nonpayment of the Obligations and the
nature, scope and extent of the risks which REA assumes and incurs hereunder,
and agrees that the Agent and the other Lenders shall have no duty to advise REA
of information known to them regarding such circumstances or risks. REA warrants
and agrees that each of the waivers set forth above is made with full knowledge
of its significance and consequences and that if any of such waivers are
determined to be contrary to any applicable law or public policy, such waivers
shall be effective only to the maximum extent permitted by law.

         Section 32.11 Nature of Liability. It is the desire and intent of REA
and the Lenders that this guaranty shall be enforced against REA to the fullest
extent permissible under the laws and public policies applied in each
jurisdiction in which enforcement is sought. If, however, and to the extent
that, the obligations of REA under this guaranty shall be adjudicated to be
invalid or unenforceable for any reason (including, without limitation, because
of any applicable state or federal law relating to fraudulent conveyances or
transfers), then, solely for purposes of this Section 32 and without relieving
the Borrower or any Guarantor of liability for the Obligations, the amount of
the Obligations shall be deemed to be reduced and REA shall pay the maximum
amount of the Obligations which would be permissible under applicable law.

         Section 32.12 Rights in Bankruptcy. In the event of the business
failure of REA or if there shall be pending any bankruptcy or insolvency case or
proceeding with respect to REA under federal bankruptcy law or any other
applicable law or in connection with the insolvency of REA or if a liquidator,
receiver, or trustee shall have been appointed for REA or REA's properties or
assets, the Agent or the Lenders may file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Agent and the Lenders allowed in any proceedings relative to REA, or any of
REA's properties or assets, and, irrespective of



                                       95
<PAGE>


whether the Obligations of the Borrower guaranteed hereby shall then be due and
payable, by declaration or otherwise, the Agent or the Lenders shall be entitled
and empowered to file and prove a claim for the whole amount of any sum or sums
owing with respect to the Obligations of the Borrower guaranteed hereby, and to
collect and receive any moneys or other property payable or deliverable on any
such claim. REA covenants and agrees that upon the commencement of a voluntary
or involuntary bankruptcy proceeding by or against Borrower, REA shall not seek
a supplemental stay or otherwise pursuant to 11 U.S.C. Section 105 or any other
provision of the Bankrutpcy Reform Act of 1978, as amended, or any other debtor
relief law (whether statutory, common law, case law, or otherwise) of any
jurisdiction whatsoever, now or hereafter in effect, which may be or become
applicable, to stay, interdict, condition, reduce or inhibit the ability of the
Agent or the Lenders to enforce any rights of the Agent or the Lenders against
REA by virtue of this guaranty or otherwise.

         Section 32.13 Set-off. REA hereby grants to each Lender, as security
for the full and prompt payment and performance of REA's obligations hereunder,
a continuing lien on and security interest in any and all securities or other
property belonging to REA now or hereafter held by such Lender and in any and
all deposits (general or specific, time or demand, provisional or final,
regardless of currency, maturity, or the branch of such Lender where the
deposits are held) now or hereafter held by such Lender and other sums credited
by or due from such Lender to REA or subject to withdrawal by REA; and
regardless of the adequacy of any collateral or other means of obtaining
repayment of such obligations, during the continuance of any Event of Default
under the Notes or the other Loan Documents, each Lender may at any time and
without notice to REA set-off and apply the whole or any portion or portions of
any or all such deposits and other sums against amounts payable under this
guaranty, whether or not any other Person or Persons could withdraw money
therefrom. Any security now or hereafter held by or for REA and provided by the
Borrower, or by anyone on Borrower's behalf, in respect of liabilities of REA
hereunder shall be held in trust for the Lenders as security for the liabilities
of REA hereunder.

         Section 32.14 Assignment. This guaranty is assignable by any Lender in
whole or in part in conjunction with any assignment of the Notes or portions
thereof, and any assignment hereof or any transfer or assignment of the Notes or
portions thereof by such Lender shall operate to vest in any such assignee the
rights and powers, in whole or in part, as appropriate, herein conferred upon
and granted to such Lender.

                          REGISTRATION RIGHTS AGREEMENT


                  THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made
and entered into as of July 9, 1998 by and between American Real Estate
Investment Corporation, a Maryland corporation (the "Company"), and the holders
of shares of common stock listed on Schedule A attached hereto including their
respective successors, assigns and transferees (herein referred to individually
as a "Holder" and collectively as the "Holders").

                  WHEREAS, on the date hereof, each Holder is receiving such
number of shares of common stock, par value $.001 per share (the "Common
Stock"), of the Company set forth opposite such Holder's name on Schedule A
attached hereto (the "Registrable Securities");

                  WHEREAS, in connection therewith, the Company has agreed to
grant to Holders the Registration Rights (as defined in Section 1 hereof);

                  NOW, THEREFORE, the parties hereto, in consideration of the
foregoing, the mutual covenants and agreements hereinafter set forth, and other
good and valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, hereby agree as follows:

Section 1.        Registration Rights

                  Each Holder shall be entitled to offer for sale from time to
time pursuant to a shelf registration statement the Registrable Securities,
subject to the terms and conditions set forth herein (the "Registration
Rights").

                  1.1      Registration Rights.

                           (a) Registration Procedure. The Company will cause to
         be filed with the Securities and Exchange Commission (the "SEC") within
         ten (10) days of the date of this Agreement a shelf registration
         statement and related prospectus, including any preliminary prospectus
         and documents incorporated by reference (the "Shelf Registration
         Statement") that complies as to form in all material respects with
         applicable SEC rules providing for the sale by each of the Holders of
         such Holder's Registrable Securities, and agrees (subject to Section
         1.2 hereof) to use its commercially reasonable best efforts to cause
         such Shelf Registration Statement to be declared effective by the SEC
         as soon as practicable thereafter. Each Holder agrees to provide in a
         timely manner information regarding the proposed distribution by such
         Holder of the Registrable Securities and such other information
         reasonably requested by the Company in connection with the preparation
         of and for inclusion in the Shelf Registration Statement. The Company
         agrees (subject to Section 1.2 hereof) to use its commercially
         reasonable best efforts to keep the Registration Statement effective
         and free of material misstatements or omissions (including the
         preparation and filing of any amendments and supplements necessary for
         that purpose) until the earlier of (i) the first date on which all
         Holders have consummated the sale of all of such Holders' Registrable
         Securities registered under the Shelf Registration Statement, (ii) the
         date on which all of the Registrable Securities are eligible for sale
         pursuant to Rule 144(k) (or any successor provision) or in a single
         transaction pursuant to Rule 144(e) (or any successor provision) under
         the Securities Act of 1933, as amended (the "Securities Act") or (iii)
         the second anniversary of the date of this 



<PAGE>


         Agreement. The Company agrees to provide to each Holder a reasonable
         number of copies of the final Shelf Registration Statement and the
         related prospectus (including any preliminary prospectus) and any
         amendments or supplements thereto. The Company further agrees that it
         will use commercially reasonable efforts to obtain the withdrawal of
         any order suspending the effectiveness of the Shelf Registration
         Statement at the earliest possible moment.

                           (b) Offers and Sales. All offers and sales by each
         Holder under the Shelf Registration Statement referred to in this
         Section 1.1, if any, shall be completed within the period during which
         the Registration Statement is required to remain effective pursuant to
         Section 1.1(a), and, upon expiration of such period, no Holder will
         offer or sell any Registrable Securities under the Registration
         Statement. If directed by the Company, each Holder will return all
         undistributed copies of the Prospectus in its possession upon the
         expiration of such period. Each Holder shall promptly, but in any event
         no later than two (2) business days after a sale by such Holder of
         Registrable Securities, notify the Company of any sale or other
         transfer by such Holder of Registrable Securities and include in such
         notice the number of Registrable securities sold or transferred by
         Holder.

                           (c) Limitations. Each Holder agrees not to offer,
         sell, offer or contract to sell, transfer, assign, grant any option for
         the sale of, pledge or encumber, or otherwise convey any shares of
         Common Stock until the first business day after the first anniversary
         of this Agreement.

                  1.2      Suspension of Offering.

                           (a) If the Company determines in its good faith
         judgment that the filing of the Shelf Registration Statement under
         Section 1.1 hereof or the use of any prospectus would materially
         impede, delay or interfere with any pending material financing,
         acquisition or corporate reorganization or other material corporate
         development involving the Company or any of its subsidiaries, or
         require the disclosure of important information which the Company has a
         material business purpose for preserving as confidential or the
         disclosure of which would materially impede the Company's ability to
         consummate a significant transaction, upon written notice of such
         determination by the Company, the rights of each Holder to offer, sell
         or distribute any Registrable Securities pursuant to the Shelf
         Registration Statement or to require the Company to take action with
         respect to the registration or sale of any Registrable Securities
         pursuant to the Shelf Registration Statement (including any action
         contemplated by Section 1.1 hereof) will be suspended until the date
         upon which the Company notifies the Holders in writing that suspension
         of such rights for the grounds set forth in this Section 1.2(a) is no
         longer necessary, but, in any event, no such period shall extend for
         longer than 45 days; provided the Company may deliver only two such
         notices in any twelve month period.

                           (b) In the case of the registration of any
         underwritten public offering proposed by the Company (other than any
         registration by the Company on Form S-8, or a successor or
         substantially similar form, of (A) an employee stock option, stock
         purchase or compensation plan or of securities issued or issuable
         pursuant to any such plan or (B) a dividend reinvestment plan), each
         Holder agrees, if requested in writing by the managing underwriter or
         underwriters administering such offering, not to effect any
         underwritten offering for the resale of Registrable Securities (or any
         option or right to acquire Registrable Securities) during the period
         commencing on the 7th day prior to the expected effective date of the
         registration statement covering such underwritten public offering or
         the date on which the proposed offering is expected to commence (which
         date shall be stated in such notice) and ending on the date specified
         by such managing underwriter in such 



                                        2
<PAGE>


         written request to such Holder, which date shall not be later than 45
         days after such expected date of effectiveness or the commencement of
         the offering, as the case may be.

                  1.3 Expenses. The Company shall pay all expenses incident to
the performance by it of its registration obligations under this Section 1,
including (i) all stock exchange, SEC and state securities registration, listing
and filing fees, (ii) all expenses incurred in connection with the preparation,
printing and distributing of the Shelf Registration Statement and prospectus
(including all expenses incurred in connection with the delivery to any Holder
of such number of copies of any prospectus as such Holder may reasonably
request), and (iii) fees and disbursements of counsel for the Company and of the
independent public accountants of the Company. Each Holder shall be responsible
for the payment of any brokerage and sales commissions, fees and disbursements
of such Holder's counsel, and any transfer taxes relating to the sale or
disposition of the Registrable Securities by such Holder.

                  1.4 Qualification. The Company agrees to use its commercially
reasonable efforts to register or qualify the Registrable Securities by the time
the Shelf Registration Statement is declared effective by the SEC under all
applicable state securities or "blue sky" laws of such jurisdictions as any
Holder shall reasonably request in writing, to keep each such registration or
qualification effective during the period the Shelf Registration Statement is
required to be kept effective, and to do any and all other acts and things which
may be reasonably necessary or advisable to enable each Holder to consummate the
disposition in each such jurisdiction of the Registrable Securities owned by
such Holder; provided, however, that the Company shall not be required to (x)
qualify generally to do business in any jurisdiction or to register as a broker
or dealer in such jurisdiction where it would not otherwise be required to
qualify but for this Section 1.4, (y) subject itself to taxation in any such
jurisdiction, or (z) submit to the general service of process in any such
jurisdiction.

                  1.5 Notices to Holders. Subject to Section 1.1(a) hereof,
during the period that the Company is required to keep the Shelf Registration
Statement effective, the Company will advise the Holders within a reasonable
time (i) when the prospectus or any prospectus supplement or post-effective
amendment thereto has been filed, and when the same has become effective, (ii)
of any request by the SEC for any amendments to, or issuance by the SEC of any
stop order with respect to the Shelf Registration Statement or any prospectus or
amendment thereto, or (iii) that an amendment or supplement to the most recent
Prospectus or prospectus supplement, as the case may be, is necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

                  1.6 Listing. The Company agrees to use its reasonable efforts
to cause all Registrable Securities to be listed on any securities exchange on
which similar securities issued by the Company are listed.

Section 2.        Indemnification

                  2.1 Indemnification by the Company. The Company agrees to
indemnify and hold harmless each Holder and each person, if any, who controls
any Holder within the meaning of Section 15 of the Securities Act or Section 20
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as
follows:

                           (a) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of or based
         upon any untrue statement or alleged untrue statement of a material
         fact contained in any registration statement (or any amendment thereto)
         pursuant to which 



                                        2
<PAGE>


         the Registrable Securities were registered under the Securities Act,
         including all documents incorporated therein by reference, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of or based upon any untrue statement or
         alleged untrue statement of a material fact contained in any
         prospectus (or any amendment or supplement thereto), including all
         documents incorporated therein by reference, or the omission or
         alleged omission therefrom of a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading;

                           (b) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         the Company, which consent shall not be unreasonably withheld; and

                           (c) against any and all expense whatsoever, as
         incurred (including reasonable fees and disbursements of counsel),
         reasonably incurred in investigating, preparing or defending against
         any litigation, or investigation or proceeding by any governmental
         agency or body, commenced or threatened, in each case whether or not a
         party, or any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission, to the
         extent that any such expense is not paid under subparagraph (a) or (b)
         above;

provided, however, that the indemnity provided pursuant to this Section 2.1 does
not apply to any Holder with respect to any loss, liability, claim, damage or
expense to the extent arising out of (i) any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such Holder
expressly for use in the Shelf Registration Statement (or any amendment thereto)
or the related prospectus (or any amendment or supplement thereto), or (ii) such
Holder's failure to deliver an amended or supplemental Prospectus (provided such
Holder was notified in writing pursuant to Section 1.5, or otherwise, of the
need for an amended or supplemental Prospectus) if such loss, liability, claim,
damage or expense would not have arisen had such delivery occurred.

                  2.2 Indemnification by Holder. Each Holder (on a several and
not joint basis) agrees to indemnify and hold harmless the Company, and each of
its directors and officers (including each director and officer of the Company
who signed a Registration Statement), and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, as follows:

                           (a) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of or based
         upon any untrue statement or alleged untrue statement of a material
         fact contained in any registration statement (or any amendment thereto)
         pursuant to which the Registrable Securities were registered under the
         Securities Act, including all documents incorporated therein by
         reference, or the omission or alleged omission therefrom of a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading or arising out of or based upon any untrue
         statement or alleged untrue statement of a material fact contained in
         any prospectus (or any amendment or supplement thereto), including all
         documents incorporated therein by reference, or the omission or alleged
         omission therefrom of a material fact necessary in 



                                        3
<PAGE>


         order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                           (b) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         Holder, which consent shall not be unreasonably withheld; and

                           (c) against any and all expense whatsoever, as
         incurred (including reasonable fees and disbursements of counsel),
         reasonably incurred in investigating, preparing or defending against
         any litigation, or investigation or proceeding by any governmental
         agency or body, commenced or threatened, in each case whether or not a
         party, or any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission, to the
         extent that any such expense is not paid under subparagraph (a) or (b)
         above;

provided, however, that the indemnity provided pursuant to this Section 2.2
shall only apply with respect to any loss, liability, claim, damage or expense
to the extent arising out of (i) any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with
written information furnished to the Company by or on behalf of such Holder
expressly for use in the Registration Statement (or any amendment thereto) or
the related prospectus (or any amendment or supplement thereto), or (ii) such
Holder's failure to deliver an amended or supplemental prospectus (provided such
Holder was notified in writing pursuant to Section 1.5, or otherwise, of the
need for an amended or supplemental Prospectus) if such loss, liability, claim,
damage or expense would not have arisen had such delivery occurred.
Notwithstanding the provisions of this Section 2.2, no Holder shall be required
to indemnify the Company, its officers, directors or control persons with
respect to any amount in excess of the amount of the total proceeds to such
Holder from sales of the Registrable Securities of such Holder under the Shelf
Registration Statement (after deducting the amounts already paid to the Company
by such Holder or any person, if any, who controls such Holder pursuant to this
Section 2.2), and no Holder shall be liable under this Section 2.2 for any
statements or omissions of any other Holder.

                  2.3 Conduct of Indemnification Proceedings. The indemnified
party shall give reasonably prompt notice to the indemnifying party of any
action or proceeding commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify the indemnifying party (i) shall not
relieve it from any liability which it may have under the indemnity agreement
provided in Section 2.1 or 2.2 above, unless and to the extent it did not
otherwise learn of such action and the lack of notice by the indemnified party
results in the forfeiture by the indemnifying party of substantial rights or
defenses, and (ii) shall not, in any event, relieve the indemnifying party from
any obligations to the indemnified party other than the indemnification
obligation provided under Section 2.1 or 2.2 above. If the indemnifying party so
elects within a reasonable time after receipt of such notice, the indemnifying
party may assume the defense of such action or proceeding at such indemnifying
party's own expense with counsel chosen by the indemnifying party and approved
by the indemnified party, which approval shall not be unreasonably withheld;
provided, however, that the indemnifying party will not settle any such action
or proceeding without the written consent of the indemnified party unless, as a
condition to such settlement, the indemnifying party secures the unconditional
release of the indemnified party; and provided further, that if the indemnified
party reasonably determines that a conflict of interest exists where it is
advisable for the indemnified party to be represented by separate counsel or
that, upon advice of counsel, there may be legal 



                                       4
<PAGE>


defenses available to it which are different from or in addition to those
available to the indemnifying party, then the indemnifying party shall not be
entitled to assume such defense and the indemnified party shall be entitled to
separate counsel at the indemnifying party's expense. If the indemnifying party
is not entitled to assume the defense of such action or proceeding as a result
of the proviso to the preceding sentence, the indemnifying party's counsel shall
be entitled to conduct the indemnifying party's defense and counsel for the
indemnified party shall be entitled to conduct the defense of the indemnified
party, it being understood that both such counsel will cooperate with each other
to conduct the defense of such action or proceeding as efficiently as possible.
If the indemnifying party (i) is not so entitled to assume the defense of such
action, (ii) does not assume such defense, after having received the notice
referred to in the first sentence of this paragraph, or (iii) fails to employ
counsel that is reasonably satisfactory to the indemnified party, after having
received the notice referred to in the first sentence of this paragraph, the
indemnifying party will pay the reasonable fees and expenses of counsel for the
indemnified party. In such event, however, the indemnifying party will not be
liable for any settlement effected without the written consent of the
indemnifying party, which consent shall not be unreasonably withheld. If an
indemnifying party is entitled to assume, and assumes, the defense of such
action or proceeding in accordance with this paragraph, the indemnifying party
shall not be liable for any fees and expenses of counsel for the indemnified
party incurred thereafter in connection with such action or proceeding.

                  2.4 Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
this Section 2 is for any reason held to be unenforceable by the indemnified
party although applicable in accordance with its terms, the Company and the
applicable Holder shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Company and such Holder, (i) in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and
such Holder on the other hand, in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or expenses, or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative fault
of but also the relative benefits to the Company on the one hand and such Holder
on the other hand, from the purchase and sale of the Registrable Securities, in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits to the indemnifying party and
indemnified party shall be determined by reference to, among other things, the
total proceeds received by the indemnifying party and indemnified party in
connection with the offering to which such losses, claims, damages, liabilities
or expenses relate. The relative fault of the indemnifying party and indemnified
party shall be determined by reference to, among other things, whether the
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact, has been
made by, or relates to information supplied by, the indemnifying party or the
indemnified party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The obligations
of each Holder under this Section 2.4 are several and not joint.

                  The parties hereto agree that it would not be just or
equitable if contribution pursuant to this Section 2.4 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 2.4, no Holder shall
be required to contribute any amount in excess of the amount of the total
proceeds to that Holder from sales of the Registrable Securities of such Holder
under the Shelf Registration Statement.

                  Notwithstanding the foregoing, no person guilty of fraudulent
misrepresentation (within the 



                                       5
<PAGE>


meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 2.4, each person, if any, who
controls any Holder within the meaning of Section 15 of the Securities Act shall
have the same rights to contribution as such Holder, and each director of the
Company, each officer of the Company who signed a registration statement and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act shall have the same rights to contribution as the Company.

Section 3.        Rule 144 Compliance

                  The Company covenants that it will file the reports required
to be filed by the Company under the Securities Act and the Exchange Act so as
to enable each Holder to sell Registrable Securities, pursuant to Rule 144 under
the Securities Act. In connection with any sale, transfer or other disposition
by any Holder of any Registrable Securities pursuant to Rule 144 under the
Securities Act, the Company shall cooperate with such Holder to facilitate the
timely preparation and delivery of certificates representing Registrable
Securities to be sold and not bearing any Securities Act legend, and enable
certificates for such Registrable Securities to be for such number of shares and
registered in such names as such Holder may reasonably request at least five (5)
business days prior to any sale of Registrable Securities hereunder.

Section 4.        Miscellaneous

                  4.1 Integration; Amendment. This Agreement constitutes the
entire agreement among the parties hereto with respect to the matters set forth
herein and supersedes and renders of no force and effect all prior oral or
written agreements, commitments and understandings among the parties with
respect to the matters set forth herein. Except as otherwise expressly provided
in this Agreement, no amendment, modification or discharge of this Agreement
shall be valid or binding unless set forth in writing and duly executed by the
Company and the applicable Holder.

                  4.2 Waivers. No waiver by a party hereto shall be effective
unless made in a written instrument duly executed by the party against whom such
waiver is sought to be enforced, and only to the extent set forth in such
instrument. Neither the waiver by any of the parties hereto of a breach or a
default under any of the provisions of this Agreement, nor the failure of any of
the parties, on one or more occasions, to enforce any of the provisions of this
Agreement or to exercise any right or privilege hereunder shall thereafter be
construed as a waiver of any subsequent breach or default of a similar nature,
or as a waiver of any such provisions, rights or privileges hereunder.

                  4.3 Assignment. This Agreement shall inure to the benefit of
and be binding on the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders. If any successor, assignee or transferee of any
Holder shall acquire Registrable Securities, in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding Registrable Securities
such Person shall be conclusively deemed to have agreed to be bound by all of
the terms and provisions hereof.

                  4.4 Notices. All notices, payments, demands or other
communications given hereunder shall be deemed to have been duly given and
received (i) upon personal delivery, (ii) in the case of notices sent within,
and for delivery within, the United States, as of the date shown on the return
receipt after mailing by registered or certified mail, return receipt requested,
postage prepaid, or (iii) the second succeeding business day after deposit with
Federal Express or other equivalent air courier delivery service, 



                                       6
<PAGE>


unless the notice is held or retained by the customs service, in which case the
date shall be the fifth succeeding business day after such deposit.

                  4.5 Specific Performance. The parties hereto acknowledge that
the obligations undertaken by them hereunder are unique and that there would be
no adequate remedy at law if any party fails to perform any of its obligations
hereunder, and accordingly agree that each party, in addition to any other
remedy to which it may be entitled at law or in equity, shall be entitled to (i)
compel specific performance of the obligations, covenants and agreements of any
other party under this Agreement in accordance with the terms and conditions of
this Agreement and (ii) obtain preliminary injunctive relief to secure specific
performance and to prevent a breach or contemplated breach of this Agreement in
any court of the United States or any State thereof having jurisdiction.

                  4.6 Governing Law. This Agreement, the rights and obligations
of the parties hereto, and any claims or disputes relating thereto, shall be
governed by and construed in accordance with the laws of the State of New York,
without giving effect to the choice of law rules thereof. The parties agree that
all disputes between any of them arising out of, connected with, related to, or
incidental to the relationship established between them in connection with this
Agreement, and whether arising in law or in equity or otherwise, shall be
resolved by the federal or state courts located in New York, New York. Nothing
herein shall affect the right of any party to serve process in any other manner
permitted by law or to commence legal proceedings or otherwise proceed against
the other in any other jurisdiction. In addition, each of the parties hereto
consents to submit to the personal jurisdiction of any federal or state court
located in the state of New York in the event that any dispute arises out of
this Agreement. The parties, for themselves and their respective affiliates,
hereby irrevocably waive all right to a trial by jury in any action, proceeding
or counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to the actions of the parties or their respective affiliates pursuant
to this Agreement in the negotiation, administration, performance or enforcement
thereof.

                  4.7 Headings. Section and subsection headings contained in
this Agreement are inserted for convenience of reference only, shall not be
deemed to be a part of this Agreement for any purpose, and shall not in any way
define or affect the meaning, construction or scope of any of the provisions
hereof.

                  4.8 Pronouns. All pronouns and any variations thereof shall be
deemed to refer to the masculine, feminine, neuter, singular or plural, as the
identity of the person or entity may require.

                  4.9 Execution in Counterparts. To facilitate execution, this
Agreement may be executed in as many counterparts as may be required. It shall
not be necessary that the signature of or on behalf of each party appears on
each counterpart, but it shall be sufficient that the signature of or on behalf
of each party appears on one or more of the counterparts. All counterparts shall
collectively constitute a single agreement. It shall not be necessary in any
proof of this Agreement to produce or account for more than a number of
counterparts containing the respective signatures of or on behalf of all of the
parties hereto.

                  4.10 Severability. If fulfillment of any provision of this
Agreement, at the time such fulfillment shall be due, shall transcend the limit
of validity prescribed by law, then the obligation to be fulfilled shall be
reduced to the limit of such validity; and if any clause or provision contained
in this Agreement operates or would operate to invalidate this Agreement, in
whole or in part, then such clause or provision only shall be held ineffective,
as though not herein contained, and the remainder of this 



                                       7
<PAGE>


Agreement shall remain operative and in full force and effect.

                  IN WITNESS WHEREOF, each of the parties hereto has caused this
Agreement to be duly executed on its behalf as of the date first hereinabove set
forth.

                          REGISTRATION RIGHTS AGREEMENT


                  THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made
and entered into as of July 9, 1998 by and between American Real Estate
Investment Corporation, a Maryland corporation (the "Company"), and the holders
of shares of common stock listed on Schedule A attached hereto including their
respective successors, assigns and transferees (herein referred to individually
as a "Holder" and collectively as the "Holders").

                  WHEREAS, on the date hereof, each Holder is receiving such
number of shares of common stock, par value $.001 per share (the "Common
Stock"), of the Company set forth opposite such Holder's name on Schedule A
attached hereto (the "Registrable Securities");

                  WHEREAS, in connection therewith, the Company has agreed to
grant to Holders the Registration Rights (as defined in Section 1 hereof);

                  NOW, THEREFORE, the parties hereto, in consideration of the
foregoing, the mutual covenants and agreements hereinafter set forth, and other
good and valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, hereby agree as follows:

Section 1.        Registration Rights

                  Each Holder shall be entitled to offer for sale from time to
time pursuant to a shelf registration statement the Registrable Securities,
subject to the terms and conditions set forth herein (the "Registration
Rights").

                  1.1      Registration Rights.

                           (a) Registration Procedure. The Company will cause to
         be filed with the Securities and Exchange Commission (the "SEC") within
         ten (10) days of the date of this Agreement a shelf registration
         statement and related prospectus, including any preliminary prospectus
         and documents incorporated by reference (the "Shelf Registration
         Statement") that complies as to form in all material respects with
         applicable SEC rules providing for the sale by each of the Holders of
         such Holder's Registrable Securities, and agrees (subject to Section
         1.2 hereof) to use its commercially reasonable best efforts to cause
         such Shelf Registration Statement to be declared effective by the SEC
         as soon as practicable thereafter. Each Holder agrees to provide in a
         timely manner information regarding the proposed distribution by such
         Holder of the Registrable Securities and such other information
         reasonably requested by the Company in connection with the preparation
         of and for inclusion in the Shelf Registration Statement. The Company
         agrees (subject to Section 1.2 hereof) to use its commercially
         reasonable best efforts to keep the Registration Statement effective
         and free of material misstatements or omissions (including the
         preparation and filing of any amendments and supplements necessary for
         that purpose) until the earlier of (i) the first date on which all
         Holders have consummated the sale of all of such Holders' Registrable
         Securities registered under the Shelf Registration Statement, (ii) the
         date on which all of the Registrable Securities are eligible for sale
         pursuant to Rule 144(k) (or any successor provision) or in a single
         transaction pursuant to Rule 144(e) (or any successor provision) under
         the Securities Act of 1933, as amended (the "Securities Act") or (iii)
         the second anniversary of the date of this 


<PAGE>


         Agreement. The Company agrees to provide to each Holder a reasonable
         number of copies of the final Shelf Registration Statement and the
         related prospectus (including any preliminary prospectus) and any
         amendments or supplements thereto. The Company further agrees that it
         will use commercially reasonable efforts to obtain the withdrawal of
         any order suspending the effectiveness of the Shelf Registration
         Statement at the earliest possible moment.

                           (b) Offers and Sales. All offers and sales by each
         Holder under the Shelf Registration Statement referred to in this
         Section 1.1, if any, shall be completed within the period during which
         the Registration Statement is required to remain effective pursuant to
         Section 1.1(a), and, upon expiration of such period, no Holder will
         offer or sell any Registrable Securities under the Registration
         Statement. If directed by the Company, each Holder will return all
         undistributed copies of the Prospectus in its possession upon the
         expiration of such period. Each Holder shall promptly, but in any event
         no later than two (2) business days after a sale by such Holder of
         Registrable Securities, notify the Company of any sale or other
         transfer by such Holder of Registrable Securities and include in such
         notice the number of Registrable securities sold or transferred by
         Holder.

                           (c) Limitations. Each Holder agrees not to offer,
         sell, offer or contract to sell, transfer, assign, grant any option for
         the sale of, pledge or encumber, or otherwise convey any shares of
         Common Stock until the first business day after the first anniversary
         of this Agreement.

                  1.2      Suspension of Offering.

                           (a) If the Company determines in its good faith
         judgment that the filing of the Shelf Registration Statement under
         Section 1.1 hereof or the use of any prospectus would materially
         impede, delay or interfere with any pending material financing,
         acquisition or corporate reorganization or other material corporate
         development involving the Company or any of its subsidiaries, or
         require the disclosure of important information which the Company has a
         material business purpose for preserving as confidential or the
         disclosure of which would materially impede the Company's ability to
         consummate a significant transaction, upon written notice of such
         determination by the Company, the rights of each Holder to offer, sell
         or distribute any Registrable Securities pursuant to the Shelf
         Registration Statement or to require the Company to take action with
         respect to the registration or sale of any Registrable Securities
         pursuant to the Shelf Registration Statement (including any action
         contemplated by Section 1.1 hereof) will be suspended until the date
         upon which the Company notifies the Holders in writing that suspension
         of such rights for the grounds set forth in this Section 1.2(a) is no
         longer necessary, but, in any event, no such period shall extend for
         longer than 45 days; provided the Company may deliver only two such
         notices in any twelve month period.

                           (b) In the case of the registration of any
         underwritten public offering proposed by the Company (other than any
         registration by the Company on Form S-8, or a successor or
         substantially similar form, of (A) an employee stock option, stock
         purchase or compensation plan or of securities issued or issuable
         pursuant to any such plan or (B) a dividend reinvestment plan), each
         Holder agrees, if requested in writing by the managing underwriter or
         underwriters administering such offering, not to effect any
         underwritten offering for the resale of Registrable Securities (or any
         option or right to acquire Registrable Securities) during the period
         commencing on the 7th day prior to the expected effective date of the
         registration statement covering such underwritten public offering or
         the date on which the proposed offering is expected to commence (which
         date shall be stated in such notice) and ending on the date specified
         by such managing underwriter in such 



                                       2
<PAGE>


         written request to such Holder, which date shall not be later than 45
         days after such expected date of effectiveness or the commencement of
         the offering, as the case may be.

                  1.3 Expenses. The Company shall pay all expenses incident to
the performance by it of its registration obligations under this Section 1,
including (i) all stock exchange, SEC and state securities registration, listing
and filing fees, (ii) all expenses incurred in connection with the preparation,
printing and distributing of the Shelf Registration Statement and prospectus
(including all expenses incurred in connection with the delivery to any Holder
of such number of copies of any prospectus as such Holder may reasonably
request), and (iii) fees and disbursements of counsel for the Company and of the
independent public accountants of the Company. Each Holder shall be responsible
for the payment of any brokerage and sales commissions, fees and disbursements
of such Holder's counsel, and any transfer taxes relating to the sale or
disposition of the Registrable Securities by such Holder.

                  1.4 Qualification. The Company agrees to use its commercially
reasonable efforts to register or qualify the Registrable Securities by the time
the Shelf Registration Statement is declared effective by the SEC under all
applicable state securities or "blue sky" laws of such jurisdictions as any
Holder shall reasonably request in writing, to keep each such registration or
qualification effective during the period the Shelf Registration Statement is
required to be kept effective, and to do any and all other acts and things which
may be reasonably necessary or advisable to enable each Holder to consummate the
disposition in each such jurisdiction of the Registrable Securities owned by
such Holder; provided, however, that the Company shall not be required to (x)
qualify generally to do business in any jurisdiction or to register as a broker
or dealer in such jurisdiction where it would not otherwise be required to
qualify but for this Section 1.4, (y) subject itself to taxation in any such
jurisdiction, or (z) submit to the general service of process in any such
jurisdiction.

                  1.5 Notices to Holders. Subject to Section 1.1(a) hereof,
during the period that the Company is required to keep the Shelf Registration
Statement effective, the Company will advise the Holders within a reasonable
time (i) when the prospectus or any prospectus supplement or post-effective
amendment thereto has been filed, and when the same has become effective, (ii)
of any request by the SEC for any amendments to, or issuance by the SEC of any
stop order with respect to the Shelf Registration Statement or any prospectus or
amendment thereto, or (iii) that an amendment or supplement to the most recent
Prospectus or prospectus supplement, as the case may be, is necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

                  1.6 Listing. The Company agrees to use its reasonable efforts
to cause all Registrable Securities to be listed on any securities exchange on
which similar securities issued by the Company are listed.

Section 2.        Indemnification

                  2.1 Indemnification by the Company. The Company agrees to
indemnify and hold harmless each Holder and each person, if any, who controls
any Holder within the meaning of Section 15 of the Securities Act or Section 20
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as
follows:

                           (a) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of or based
         upon any untrue statement or alleged untrue statement of a material
         fact contained in any registration statement (or any amendment thereto)
         pursuant to which 



                                        3
<PAGE>


         the Registrable Securities were registered under the Securities Act,
         including all documents incorporated therein by reference, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of or based upon any untrue statement or
         alleged untrue statement of a material fact contained in any
         prospectus (or any amendment or supplement thereto), including all
         documents incorporated therein by reference, or the omission or
         alleged omission therefrom of a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading;

                           (b) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         the Company, which consent shall not be unreasonably withheld; and

                           (c) against any and all expense whatsoever, as
         incurred (including reasonable fees and disbursements of counsel),
         reasonably incurred in investigating, preparing or defending against
         any litigation, or investigation or proceeding by any governmental
         agency or body, commenced or threatened, in each case whether or not a
         party, or any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission, to the
         extent that any such expense is not paid under subparagraph (a) or (b)
         above;

provided, however, that the indemnity provided pursuant to this Section 2.1 does
not apply to any Holder with respect to any loss, liability, claim, damage or
expense to the extent arising out of (i) any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such Holder
expressly for use in the Shelf Registration Statement (or any amendment thereto)
or the related prospectus (or any amendment or supplement thereto), or (ii) such
Holder's failure to deliver an amended or supplemental Prospectus (provided such
Holder was notified in writing pursuant to Section 1.5, or otherwise, of the
need for an amended or supplemental Prospectus) if such loss, liability, claim,
damage or expense would not have arisen had such delivery occurred.

                  2.2 Indemnification by Holder. Each Holder (on a several and
not joint basis) agrees to indemnify and hold harmless the Company, and each of
its directors and officers (including each director and officer of the Company
who signed a Registration Statement), and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, as follows:

                           (a) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of or based
         upon any untrue statement or alleged untrue statement of a material
         fact contained in any registration statement (or any amendment thereto)
         pursuant to which the Registrable Securities were registered under the
         Securities Act, including all documents incorporated therein by
         reference, or the omission or alleged omission therefrom of a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading or arising out of or based upon any untrue
         statement or alleged untrue statement of a material fact contained in
         any prospectus (or any amendment or supplement thereto), including all
         documents incorporated therein by reference, or the omission or alleged
         omission therefrom of a material fact necessary in 



                                        4
<PAGE>


         order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                           (b) against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         Holder, which consent shall not be unreasonably withheld; and

                           (c) against any and all expense whatsoever, as
         incurred (including reasonable fees and disbursements of counsel),
         reasonably incurred in investigating, preparing or defending against
         any litigation, or investigation or proceeding by any governmental
         agency or body, commenced or threatened, in each case whether or not a
         party, or any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission, to the
         extent that any such expense is not paid under subparagraph (a) or (b)
         above;

provided, however, that the indemnity provided pursuant to this Section 2.2
shall only apply with respect to any loss, liability, claim, damage or expense
to the extent arising out of (i) any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with
written information furnished to the Company by or on behalf of such Holder
expressly for use in the Registration Statement (or any amendment thereto) or
the related prospectus (or any amendment or supplement thereto), or (ii) such
Holder's failure to deliver an amended or supplemental prospectus (provided such
Holder was notified in writing pursuant to Section 1.5, or otherwise, of the
need for an amended or supplemental Prospectus) if such loss, liability, claim,
damage or expense would not have arisen had such delivery occurred.
Notwithstanding the provisions of this Section 2.2, no Holder shall be required
to indemnify the Company, its officers, directors or control persons with
respect to any amount in excess of the amount of the total proceeds to such
Holder from sales of the Registrable Securities of such Holder under the Shelf
Registration Statement (after deducting the amounts already paid to the Company
by such Holder or any person, if any, who controls such Holder pursuant to this
Section 2.2), and no Holder shall be liable under this Section 2.2 for any
statements or omissions of any other Holder.

                  2.3 Conduct of Indemnification Proceedings. The indemnified
party shall give reasonably prompt notice to the indemnifying party of any
action or proceeding commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify the indemnifying party (i) shall not
relieve it from any liability which it may have under the indemnity agreement
provided in Section 2.1 or 2.2 above, unless and to the extent it did not
otherwise learn of such action and the lack of notice by the indemnified party
results in the forfeiture by the indemnifying party of substantial rights or
defenses, and (ii) shall not, in any event, relieve the indemnifying party from
any obligations to the indemnified party other than the indemnification
obligation provided under Section 2.1 or 2.2 above. If the indemnifying party so
elects within a reasonable time after receipt of such notice, the indemnifying
party may assume the defense of such action or proceeding at such indemnifying
party's own expense with counsel chosen by the indemnifying party and approved
by the indemnified party, which approval shall not be unreasonably withheld;
provided, however, that the indemnifying party will not settle any such action
or proceeding without the written consent of the indemnified party unless, as a
condition to such settlement, the indemnifying party secures the unconditional
release of the indemnified party; and provided further, that if the indemnified
party reasonably determines that a conflict of interest exists where it is
advisable for the indemnified party to be represented by separate counsel or
that, upon advice of counsel, there may be legal 



                                        5
<PAGE>


defenses available to it which are different from or in addition to those
available to the indemnifying party, then the indemnifying party shall not be
entitled to assume such defense and the indemnified party shall be entitled to
separate counsel at the indemnifying party's expense. If the indemnifying party
is not entitled to assume the defense of such action or proceeding as a result
of the proviso to the preceding sentence, the indemnifying party's counsel shall
be entitled to conduct the indemnifying party's defense and counsel for the
indemnified party shall be entitled to conduct the defense of the indemnified
party, it being understood that both such counsel will cooperate with each other
to conduct the defense of such action or proceeding as efficiently as possible.
If the indemnifying party (i) is not so entitled to assume the defense of such
action, (ii) does not assume such defense, after having received the notice
referred to in the first sentence of this paragraph, or (iii) fails to employ
counsel that is reasonably satisfactory to the indemnified party, after having
received the notice referred to in the first sentence of this paragraph, the
indemnifying party will pay the reasonable fees and expenses of counsel for the
indemnified party. In such event, however, the indemnifying party will not be
liable for any settlement effected without the written consent of the
indemnifying party, which consent shall not be unreasonably withheld. If an
indemnifying party is entitled to assume, and assumes, the defense of such
action or proceeding in accordance with this paragraph, the indemnifying party
shall not be liable for any fees and expenses of counsel for the indemnified
party incurred thereafter in connection with such action or proceeding.

                  2.4 Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
this Section 2 is for any reason held to be unenforceable by the indemnified
party although applicable in accordance with its terms, the Company and the
applicable Holder shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Company and such Holder, (i) in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and
such Holder on the other hand, in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or expenses, or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative fault
of but also the relative benefits to the Company on the one hand and such Holder
on the other hand, from the purchase and sale of the Registrable Securities, in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits to the indemnifying party and
indemnified party shall be determined by reference to, among other things, the
total proceeds received by the indemnifying party and indemnified party in
connection with the offering to which such losses, claims, damages, liabilities
or expenses relate. The relative fault of the indemnifying party and indemnified
party shall be determined by reference to, among other things, whether the
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact, has been
made by, or relates to information supplied by, the indemnifying party or the
indemnified party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The obligations
of each Holder under this Section 2.4 are several and not joint.

                  The parties hereto agree that it would not be just or
equitable if contribution pursuant to this Section 2.4 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 2.4, no Holder shall
be required to contribute any amount in excess of the amount of the total
proceeds to that Holder from sales of the Registrable Securities of such Holder
under the Shelf Registration Statement.

                  Notwithstanding the foregoing, no person guilty of fraudulent
misrepresentation (within the 



                                        6
<PAGE>


meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 2.4, each person, if any, who
controls any Holder within the meaning of Section 15 of the Securities Act shall
have the same rights to contribution as such Holder, and each director of the
Company, each officer of the Company who signed a registration statement and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act shall have the same rights to contribution as the Company.

Section 3.        Rule 144 Compliance

                  The Company covenants that it will file the reports required
to be filed by the Company under the Securities Act and the Exchange Act so as
to enable each Holder to sell Registrable Securities, pursuant to Rule 144 under
the Securities Act. In connection with any sale, transfer or other disposition
by any Holder of any Registrable Securities pursuant to Rule 144 under the
Securities Act, the Company shall cooperate with such Holder to facilitate the
timely preparation and delivery of certificates representing Registrable
Securities to be sold and not bearing any Securities Act legend, and enable
certificates for such Registrable Securities to be for such number of shares and
registered in such names as such Holder may reasonably request at least five (5)
business days prior to any sale of Registrable Securities hereunder.

Section 4.        Miscellaneous

                  4.1 Integration; Amendment. This Agreement constitutes the
entire agreement among the parties hereto with respect to the matters set forth
herein and supersedes and renders of no force and effect all prior oral or
written agreements, commitments and understandings among the parties with
respect to the matters set forth herein. Except as otherwise expressly provided
in this Agreement, no amendment, modification or discharge of this Agreement
shall be valid or binding unless set forth in writing and duly executed by the
Company and the applicable Holder.

                  4.2 Waivers. No waiver by a party hereto shall be effective
unless made in a written instrument duly executed by the party against whom such
waiver is sought to be enforced, and only to the extent set forth in such
instrument. Neither the waiver by any of the parties hereto of a breach or a
default under any of the provisions of this Agreement, nor the failure of any of
the parties, on one or more occasions, to enforce any of the provisions of this
Agreement or to exercise any right or privilege hereunder shall thereafter be
construed as a waiver of any subsequent breach or default of a similar nature,
or as a waiver of any such provisions, rights or privileges hereunder.

                  4.3 Assignment. This Agreement shall inure to the benefit of
and be binding on the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders. If any successor, assignee or transferee of any
Holder shall acquire Registrable Securities, in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding Registrable Securities
such Person shall be conclusively deemed to have agreed to be bound by all of
the terms and provisions hereof.

                  4.4 Notices. All notices, payments, demands or other
communications given hereunder shall be deemed to have been duly given and
received (i) upon personal delivery, (ii) in the case of notices sent within,
and for delivery within, the United States, as of the date shown on the return
receipt after mailing by registered or certified mail, return receipt requested,
postage prepaid, or (iii) the second succeeding business day after deposit with
Federal Express or other equivalent air courier delivery service, 



                                        7
<PAGE>


unless the notice is held or retained by the customs service, in which case 
the date shall be the fifth succeeding business day after such deposit.

                  4.5 Specific Performance. The parties hereto acknowledge that
the obligations undertaken by them hereunder are unique and that there would be
no adequate remedy at law if any party fails to perform any of its obligations
hereunder, and accordingly agree that each party, in addition to any other
remedy to which it may be entitled at law or in equity, shall be entitled to (i)
compel specific performance of the obligations, covenants and agreements of any

Ladies and Gentlemen:

         This Subscription Agreement (the "Agreement") is executed by the 
undersigned in connection with the offer by American Real Estate Investment 
Corporation, a Maryland corporation (the "Company"), to sell, and the 
subscription by the undersigned to buy, shares (the "Shares") of common 
stock, par value $.001 per share, of the Company (the "Common Stock").

                                   Section 1.

         1.1 Subscription. The undersigned hereby subscribes for the number 
of Shares indicated on the counterpart signature page hereof at a price of 
$16.50 per share of Common Stock (the "Purchase Price"). In respect of this 
subscription, the undersigned herewith delivers to the Company (i) two 
executed original signature pages of this Subscription Agreement, and (ii) a 
fully completed Investor Information Sheet, Account Information Sheet, if 
applicable, Purchaser Representative's Certificate, if applicable, and 
Accredited Investor Questionnaire attached as Exhibits A, B, C and D, 
respectively.

         1.2 Closing. The purchase and sale of the Shares shall take place at 
the offices of Rogers & Wells LLP, 200 Park Avenue, New York, New York, at 
10:00 a.m., on July 9, 1998, subject to satisfaction of the conditions set 
forth in Section 4 and Section 5, or at such other time and place as the 
Company and the undersigned mutually agree (the "Closing"). At the Closing 
the Company shall deliver to the undersigned a certificate representing the 
Shares that the undersigned is purchasing, registered in such name or names 
as the undersigned shall designate at least two (2) business days prior to 
the date of the Closing, against payment of the Purchase Price thereof by 
wire transfer in immediately available funds to an account designated by the 
Company at least two (2) business days prior to the date of the Closing.

         1.3 Purchase Price Adjustment. On the earlier of (i) the first 
business day after the first anniversary of the Closing and (ii) the first 
business day after a Liquidating Event (as defined below) has occurred (the 
"Settlement Date"), the Purchase Price shall be adjusted as follows:

                  (a) If the Average Price (as defined below) is below $15.50 
per share, the Company (or its successor) shall deliver to the undersigned on 
the Settlement Date cash in an amount equal to (i) the difference between 
$15.50 and the Average Price, multiplied by (ii) the number of Shares 
purchased by the undersigned at the Closing.

                  (b) If the Average Price is above $19.50 per share, the 
undersigned shall tender 


                                        1
<PAGE>


to the Company on the Settlement Date by delivery of a certificate, duly 
endorsed for transfer in blank, for cancellation of that number of shares of 
Common Stock equal to (i) the difference between the Average Price and 
$19.50, divided by (ii) the Average Price, multiplied by (iii) the number of 
Shares purchased by the undersigned at the Closing. The number of shares of 
Common Stock to be tendered by the undersigned pursuant to this Section 
1.3(b) shall be rounded to the nearest whole share. All such shares of Common 
Stock tendered to the Company by the undersigned shall no longer be 
outstanding and shall automatically be canceled and retired and shall revert 
to the status of authorized but unissued stock, and the Company shall, if 
necessary, deliver a replacement certificate representing the remaining 
Shares owned by the undersigned.

                  (c) The "Average Price" shall be equal to the arithmetic 
average of the "Sales Price" (as hereinafter defined) on each of the Trading 
Days (as hereinafter defined) during the 30-day period preceding the 
Settlement Date. The term "Sales Price" shall mean, on any Trading Day, the 
closing price of a share of Common Stock on the American Stock Exchange or, 
if the shares are no longer listed on the American Stock Exchange, such other 
exchange or automated interdealer quotation system upon which the shares are 
then listed or quoted, or, if not listed or quoted, the Sales Price on a 
Trading Day shall be determined by independent directors of the Company 
acting in good faith on the basis of such quotations and other information as 
it considers, in its reasonable judgment, appropriate. The term "Trading Day" 
shall mean any day on which securities are traded on the American Stock 
Exchange or such other national securities exchange or automated interdealer 
quotation system upon which the shares are then trading or quoted.

                  (d) A "Liquidating Event" shall occur if (i) the Company 
sells all or substantially all of its assets and uses such proceeds solely 
either to repay debt or other liabilities of the Company and/or to pay 
dividends to the holders of Common Stock or (ii) the Company merges with and 
into another entity where the Company is not the surviving corporation and 
the surviving corporation (a) is listed on the New York Stock Exchange Inc. 
or the American Stock Exchange Inc. or quoted on the National Association of 
Securities Dealers Automated Quotation System ("NASDAQ") or the National 
Market System of NASDAQ, and (b) has an outstanding float of publicly 
available common equity in excess of $300 million (not counting for purposes 
of determining the outstanding float of any company shares held by affiliates 
of such company).

                  (e) The record date for any distribution with respect to a 
Liquidating Event described in clause (i) of the definition thereof shall be 
no earlier than the second business day following the date the Liquidating 
Event occurred.

                  (f) Notwithstanding anything in clause 1.3(ii) to the 
contrary, any agreement to merge the Company with and into another entity 
where the Company is not the surviving corporation shall provide that for 
purposes of the calculation of the amount of cash and/or the number of 
securities to be distributed to holders of Common Stock, the undersigned 
shall be deemed to hold the number of shares of Common Stock held by the 
undersigned adjusted to give effect to Section 1.3(b) as though the 
transactions contemplated therein had taken place prior to the closing of the 
merger.

                                   Section 2.

         2. Investor Representations and Warranties. The undersigned hereby 
acknowledges, represents and warrants to, and agrees with, the Company as 
follows:

         2.1 Authorization. This Agreement constitutes a valid and legally 
binding obligation on the part of the undersigned, enforceable in accordance 
with its terms except as affected by (i) bankruptcy law, and (ii) equitable 
principles. The undersigned represents that he, she or it has full power and 
authority to enter into this Agreement.

         2.2 No Advertisement or Solicitation. The undersigned acknowledges 
that the offer and sale of the Shares to him, her or it has not been 
accomplished by any form of general solicitation or general advertising, 
including, but not limited to, (i) any advertisement, article, notice or 
other communication published in any newspaper, magazine or similar media, or 
broadcast over television or radio or (ii) any seminar or meeting whose 
attendees have been invited by any general solicitation or general 
advertising.

         2.3      Restrictions on Transfer.

                  (a) The undersigned understands and acknowledges that the 
Shares have not been registered under the Securities Act of 1933, as amended 
(the "Securities Act"), or applicable state securities laws, by reason of a 
specific exemption from the registration provisions thereof which exemption 
depends upon, among other things, the bona fide nature of the investment 
intent of the undersigned as expressed herein and the accuracy and 
completeness of the other representations of the undersigned set forth herein.

                  (b) The undersigned understands and acknowledges that, 
except as provided for by the Registration Rights Agreement attached hereto 
as Exhibit E (the "Registration Rights Agreement"), none of the Shares have 
been registered under the Securities Act or registered or qualified under the 
securities laws of any state and none may be sold, transferred, assigned, 
pledged or hypothecated (i) absent effective registration thereof under the 
Securities Act and applicable state securities laws, or (ii) absent an 
opinion of counsel, which opinion is satisfactory in form and substance to 
the Company and its counsel, in their respective reasonable discretion, to 
the effect that such registration is not required under the Securities Act or 
such state securities laws or that such transaction complies with the rules 
promulgated by the Securities and Exchange Commission (the "Commission") 
under the Securities Act or such state securities laws or (iii) except in a 
transaction in compliance with Rule 144 under the Securities Act. The 
undersigned understands and acknowledges that he, she or it must bear the 
economic risks of this investment resulting from such limitations.

                  (c) The undersigned is aware of the provisions of Rule 144 
promulgated under the Securities Act, pursuant to which the undersigned may 
be able to sell the Shares, subject to certain exceptions, one year after 
they receive such Shares so long as certain current public 


                                       3
<PAGE>


information is available about the Company, the sale is through a broker in 
an unsolicited "broker's transaction" and the undersigned does not sell, in 
any three-month period, more than the greater of 1% of the outstanding Common 
Stock or the average weekly trading volume of the Shares for the four-week 
period preceding the sale. The undersigned generally will be able to sell the 
Shares without regard to any volume or other limitations discussed above 
beginning two years after they receive the Shares, unless they are affiliates 
of the Company (i.e., a person controlling, controlled by or under common 
control with the Company). Affiliates of the Company will continue to be 
subject to the volume limitations on unregistered sales following the 
expiration of the two-year period. The preceding description is a general 
summary of the restrictions of Rule 144, and each of the undersigned should 
consult with his, her or its own legal advisor to ensure compliance with all 
of the requirements of applicable federal and state securities laws and 
regulations. In this connection, the undersigned understands Rule 144 may or 
may not be available for the resale of the Shares and the undersigned should 
consult an attorney with regard to the availability of Rule 144. The Company 
is subject to the reporting requirements under the Securities Exchange Act of 
1934, as amended (the "Exchange Act"). Upon notice of issuance, the Shares 
will be listed for trading on the American Stock Exchange. If not all of the 
requirements of Rule 144 are met, registration under the Securities Act or 
some other registration exemption will be required for any disposition of the 
Shares. The undersigned understands that although Rule 144 is not exclusive, 
the Commission has expressed its opinion that persons proposing to sell 
restricted securities received in an offering other than a registered 
offering or pursuant to Rule 144 will have a substantial burden of proof in 
establishing that an exemption from registration is available for such offers 
or sales that such persons and the brokers who participate in the 
transactions do so at their own risk.

         2.4 Disclosure of Information.The undersigned and/or the 
undersigned's purchaser representative or personal advisor, as the case may 
be:

                        (i) has been furnished with and has carefully read

investment in the Company to the extent the Company possesses such 
information or can acquire it without unreasonable effort or expense, and has 
not been furnished any other offering literature or prospectus on which they 
are entitled to rely except as mentioned herein;

                        (iv) understands that the materials or documents 
provided to the undersigned and/or the undersigned's purchaser representative 
or personal advisor, as the case may be, have not been prepared by, and the 
accuracy of such materials or documents have not been verified by, Donaldson, 
Lufkin & Jenrette Securities Corporation ("DLJ") which is acting as placement 
agent in connection with the purchase and sale of the Shares. DLJ makes no 
representations or warranties with respect to the materials or documents

an investment in the Shares. The undersigned has not utilized any person as 
his, her or its purchaser representative or professional advisor in 
connection with evaluating such risks and merits or, if the undersigned has 
utilized a person as his, her or its purchaser representative or personal 
advisor to assist in evaluating the risks and merits of an investment, the 
purchaser representative or personal advisor has executed the Purchaser 
Representative's Certificate attached as Exhibit C to this Agreement. The 
undersigned acknowledges that he, she or it has the financial ability to bear 
the economic risk of his, her or its investment in the Company (including 
his, her or its possible loss), has adequate means for providing for his, her 
or its current needs and personal contingencies and has no need for liquidity 
with respect to the investment in the Company. If other than an individual,

Date"), the Purchase Price shall be adjusted as follows:

                  (a) If the Average Price (as defined below) is below $15.50
per share, the Company shall deliver to the undersigned on the Settlement Date
cash in an amount equal to (i) the difference between $15.50 and the Average
Price, multiplied by (ii) the number of Shares purchased by the undersigned at
the Closing.

                                       1

<PAGE>

                  (b) If the Average Price is above $19.50 per share, each
Holder shall tender to the Company on the Settlement Date by delivery of a
certificate, duly endorsed for transfer in blank, for cancellation of that
number of shares of Common Stock equal to (i) the difference between the Average
Price and $19.50, divided by (ii) the Average Price, multiplied by (iii) the
number of Shares purchased by such Holder at the Closing. The number of shares
of Common Stock to be tendered by the undersigned pursuant to this Section
1.3(b) shall be rounded to the nearest whole share. All such shares of Common
Stock tendered to the Company by the undersigned shall no longer be outstanding
and shall automatically be canceled and retired and shall revert to the status
of authorized but unissued stock, and the Company shall, if necessary, deliver a
replacement certificate representing the remaining Shares owned by the
undersigned.

                  (c) The "Average Price" shall be equal to the arithmetic
average of the "Sales Price" (as hereinafter defined) on each of the Trading
Days (as hereinafter defined) during the 30-day period preceding the Settlement
Date. The term "Sales Price" shall mean, on any Trading Day, the closing price
of a share of Common Stock on the American Stock Exchange or, if the shares are
no longer listed on the American Stock Exchange, such other exchange or
automated inter-dealer quotation system upon which the shares are then listed or
quoted, or, if not listed or quoted, the Sales Price on a Trading Day shall be
determined by a majority of the independent directors of the Board of Directors
of the Company acting in good faith on the basis of such quotations and other
information as it considers, in its reasonable judgment, appropriate (such
amount being the "Determined Price"). The Company shall send notice of the
Determined Price, if applicable, to the undersigned. The Holders may object to
the Determined Price by notice to the Company within 10 days after receipt of
notice from the Company. If a majority of the Shares purchased hereunder and
held by the undersigned (the "Majority Holders") object to the Determined Price,
the Company shall select an independent investment bank or other expert in
valuation of securities to calculate the Determined Price. Such bank or expert
shall be subject to the reasonable approval of the Majority Holders. The
Determined Price calculated by the bank or expert so selected and approved shall
be final and binding on all parties hereto. All costs of such independent
investment bank or other expert shall be paid by the Company. The term "Trading
Day" shall mean any day on which securities are traded on the American Stock
Exchange or such other national securities exchange or automated inter-dealer
quotation system upon which the shares are then trading or quoted.

                  (d) A "Liquidating Event" shall occur if (i) the Company sells
all or substantially all of its assets and uses such proceeds solely either to
repay debt or other liabilities of the Company and/or to pay dividends to the
holders of Common Stock or (ii) the Company merges with and into another entity
where the Company is not the surviving corporation and the surviving corporation
(a) is listed on the New York Stock Exchange Inc. or the American Stock Exchange
Inc. or quoted on the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") or the National Market System of NASDAQ, and (b) has
an outstanding float of publicly available common equity in excess of $300
million (not counting for purposes of determining the outstanding float of any
company shares held by affiliates of such company).

                  (e) The record date for any distribution with respect to a
Liquidating Event described in clause (i) of the definition thereof shall be no
earlier than the second business day 

                                       2

<PAGE>

following the date the Liquidating Event occurred.

                  (f) Notwithstanding anything in clause 1.3(ii) to the
contrary, any agreement to merge the Company with and into another entity where
the Company is not the surviving corporation shall provide that for purposes of
the calculation of the amount of cash and/or the number of securities to be
distributed to holders of Common Stock, the undersigned shall be deemed to hold
the number of shares of Common Stock held by the undersigned adjusted to give
effect to Section 1.3(b) as though the transactions contemplated therein had
taken place prior to the closing of the merger.

                                   Section 2.

         2. Investor Representations and Warranties. The undersigned hereby
acknowledges, represents and warrants to, and agrees with, the Company as
follows:

         2.1 Authorization. This Agreement constitutes a valid and legally
binding obligation on the part of the undersigned, enforceable in accordance
with its terms except as affected by (i) bankruptcy law, and (ii) equitable
principles. The undersigned represents that he, she or it has full power and
authority to enter into this Agreement.

         2.2 No Advertisement or Solicitation. The undersigned acknowledges that
the offer and sale of the Shares to him, her or it has not been accomplished by
any form of general solicitation or general advertising, including, but not
limited to, (i) any advertisement, article, notice or other communication
published in any newspaper, magazine or similar media, or broadcast over
television or radio or (ii) any seminar or meeting whose attendees have been
invited by any general solicitation or general advertising.

         2.3      Restrictions on Transfer.

                  (a) The undersigned understands and acknowledges that the
Shares have not been registered under the Securities Act of 1933, as amended
(the "Securities Act"), or applicable state securities laws, by reason of a
specific exemption from the registration provisions thereof which exemption
depends upon, among other things, the bona fide nature of the investment intent
of the undersigned as expressed herein and the accuracy and completeness of the
other representations of the undersigned set forth herein.

                  (b) The undersigned understands and acknowledges that, except
as provided for by the Registration Rights Agreement attached hereto as Exhibit
E (the "Registration Rights Agreement"), none of the Shares have been registered
under the Securities Act or registered or qualified under the securities laws of
any state and none may be sold, transferred, assigned, pledged or hypothecated
(i) absent effective registration thereof under the Securities Act and
applicable state securities laws, or (ii) absent an opinion of counsel, which
opinion is satisfactory in form and substance to the Company and its counsel, in
their respective reasonable discretion, to the effect that such registration is
not required under the Securities Act or such state securities laws or that 

                                       3

<PAGE>

such transaction complies with the rules promulgated by the Securities and
Exchange Commission (the "Commission") under the Securities Act or such state
securities laws or (iii) except in a transaction in compliance with Rule 144
under the Securities Act. The undersigned understands and acknowledges that he,
she or it must bear the economic risks of this investment resulting from such
limitations.

                  (c) The undersigned is aware of the provisions of Rule 144
promulgated under the Securities Act, pursuant to which the undersigned may be
able to sell the Shares, subject to certain exceptions, one year after they
receive such Shares so long as certain current public information is available
about the Company, the sale is through a broker in an unsolicited "broker's
transaction" and the undersigned does not sell, in any three-month period, more
than the greater of 1% of the outstanding Common Stock or the average weekly
trading volume of the Shares for the four-week period preceding the sale. The
undersigned generally will be able to sell the Shares without regard to any
volume or other limitations discussed above beginning two years after they
receive the Shares, unless they are affiliates of the Company (i.e., a person
controlling, controlled by or under common control with the Company). Affiliates
of the Company will continue to be subject to the volume limitations on
unregistered sales following the expiration of the two-year period. The
preceding description is a general summary of the restrictions of Rule 144, and
each of the undersigned should consult with his, her or its own legal advisor to
ensure compliance with all of the requirements of applicable federal and state
securities laws and regulations. In this connection, the undersigned understands
Rule 144 may or may not be available for the resale of the Shares and the
undersigned should consult an attorney with regard to the availability of Rule
144. The Company is subject to the reporting requirements under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). Upon notice of issuance,
the Shares will be listed for trading on the American Stock Exchange. If not all
of the requirements of Rule 144 are met, registration under the Securities Act
or some other registration exemption will be required for any disposition of the
Shares. The undersigned understands that although Rule 144 is not exclusive, the
Commission has expressed its opinion that persons proposing to sell restricted
securities received in an offering other than a registered offering or pursuant
to Rule 144 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales that such
persons and the brokers who participate in the transactions do so at their own
risk.

         2.4 Disclosure of Information.The undersigned and/or the undersigned's
purchaser representative or personal advisor, as the case may be:

                        (i) has been furnished with and has carefully read and

information necessary to verify the accuracy of the materials or documents that
were provided in order for him, her or it to evaluate the merits and risks of an
investment in the Company to the extent the Company possesses such information
or can acquire it without unreasonable effort or expense, and has not been
furnished any other offering literature or prospectus on which they are entitled

investment and has obtained, in his, her or its judgment, alone, or together
with his, her or its purchaser representative or personal advisor sufficient
information from the Company to evaluate the merits and risks of an investment
in the Shares. The undersigned has not utilized any person as his, her or its
purchaser representative or professional advisor in connection with evaluating
such risks and merits or, if the undersigned has utilized a person as his, her
or its purchaser representative or personal advisor to assist in evaluating the
risks and merits of an investment, the purchaser representative or personal
advisor has executed the Purchaser Representative's Certificate attached as
Exhibit C to this Agreement. The undersigned acknowledges that he, she or it has
the financial ability to bear the economic risk of his, her or its investment in
the Company (including his, her or its possible loss), has adequate means for
providing for his, her or its current needs and personal contingencies and has
no need for liquidity with respect to the investment in the Company. If other

officers, directors and stockholders necessary for the adoption, authorization,
execution, filing (where applicable) and delivery of this Agreement and the
Registration Rights Agreement, the performance of all obligations of the Company

Company, enforceable in accordance with their terms, except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of
general application affecting enforcement of creditors' rights generally, (ii)
as limited by laws relating to the availability of specific performance,

herein, will be duly and validly issued, fully paid, and nonassessable, and,

laws. The issuance and sale of the Common Stock will not violate any preemptive
rights.

information that the undersigned has requested for deciding whether to purchase
the Shares. Subject to Section 3.7, the written information and certificates
provided to the undersigned pursuant to this Agreement or the Registration

made to the undersigned any representation or warranty other than as expressly
made by the Company in Section 3 hereof. Without limiting the generality of the
foregoing, and notwithstanding any otherwise express representations and
warranties made by the Company, in this Section 3, the Company makes no
representation or warranty to the undersigned with respect to any projections,
estimates or budgets heretofore delivered to or made available to the
undersigned of future revenues, expenses or expenditures or future results of
operations.

         3.8 Shelf Registration Statement. The Company will cause to be filed
with the Securities and Exchange Commission (the "SEC") within ten (10) days of
the Closing a shelf registration statement and related prospectus (the "Shelf
Registration Statement") that complies as to form in all material respects with
applicable SEC rules providing for the sale from time to time by the Holders of
the Shares, and agrees to use its commercially reasonable best efforts to cause
such Shelf Registration Statement to be declared effective by the SEC as soon as
practicable thereafter. If the Company fails to file the Shelf Registration
Statement with the SEC within ten (10) days of the Closing, the undersigned
shall have the right, upon the timely written notice (the "Put Notice") to the
Company (which notice must be received by the Company no more than thirty-five
(35) days from the date of the Closing), to require the Company to purchase the
Shares from the undersigned within thirty (30) days of the Company's receipt of
the Put Notice at a price of $16.50 per share plus any accrued but unpaid

<PAGE>

prior to the first anniversary of the Closing. If the Company fails to
consummate a Qualifying Offering on or prior to the second anniversary of the
Closing and if, at that time, the Holders own, in the aggregate, at least 25% of
the Shares purchased by them at the Closing, the Company shall, on the second
anniversary of the Closing, pay to each Holder, as a purchase price adjustment,
an amount equal to (i) the total number of outstanding shares of Common Stock of
the Company on such second anniversary times (ii) 2.5% times (iii) a fraction,
the numerator of which is the number of Shares purchased by such Holder pursuant
to this Subscription Agreement and the denominator of which is the number of
Shares purchased by all Holders pursuant to this Subscription Agreement times
(iv) the arithmetic average of the Sales Price on each of the Trading Days
during the 30-day period ending on the third business day prior to the second
anniversary of the Closing. For the purposes of this Section 3.9, a "Qualifying
Offering" shall mean either (i) the sale of Common Stock in one or more
offerings at a price of at least $16.50 per share, to at least fifteen (15)
investors in the aggregate (provided that none of investors may purchase more
than the greater of $15 million of Common Stock (based on the net proceeds to
the Company) or 10% of the aggregate number of shares of Common Stock sold in
the Qualifying Offering), which results in net proceeds to the Company of at
least $150 million or (ii) a Liquidating Event which results in a minimum
liquidation price to the holders of Common Stock of $16.50 per share plus any
accrued but unpaid dividends.

         3.10 Preemptive Rights. The Company shall provide each Holder with
written notice of any proposed issuance for cash of Common Stock no later than
30 days prior to the proposed issuance thereof. Such notice shall specify the
purchase price, the proposed issuance date and all other material terms of such
issuance. Upon delivery to the Company by any Holder no later than 10 days after
such notice by the Company of a notice stating that such Holder intends to
acquire a portion of the Common Stock to be issued, such Holder shall be
entitled, on the terms offered by the Company to other prospective purchasers of
the Common Stock to be issued, to purchase up to an amount of the securities
such that, upon consummation of the proposed issuance, the Holder would hold the
same percentage of the Common Stock as such Holder holds immediately prior to
such issuance. Any such notice from any Holder shall indicate the amount of
Common Stock it intends to purchase and shall constitute a binding contract to
acquire such Common Stock on the terms set forth in the notice delivered to such
Holder by the Company with respect to such issuance. Notwithstanding anything
herein to the contrary, the Company shall be entitled not to proceed with the
proposed issuance or to alter the terms thereof; provided that, in the event
that any material terms of the proposed issuance are altered, (i) any notice
delivered by a Holder to the Company pursuant to this Section 3.10 shall be
revoked automatically and (ii) such Holder shall be entitled to participate in
such proposed issuance on the revised terms in accordance with this Section
3.10. The provisions of this Section 3.10 shall no longer apply and shall be of
no further effect after the Company consummates a Qualifying Offering.

                                   Section 4.
